                            (a Delaware corporation)

                                    ARTICLE I

The name of its registered agent at such address is The Corporation Trust

         1.2      OTHER OFFICES

         The board of directors may at any time establish other offices at any
place or places where the corporation is qualified to do business.

                                   ARTICLE II

                            MEETINGS OF STOCKHOLDERS

         2.1      PLACE OF MEETINGS

         Meetings of stockholders shall be held at any place, within or outside
the State of Delaware, designated by the board of directors. In the absence of
any such designation, stockholders' meetings shall be held at the registered
office of the corporation.

         2.2      ANNUAL MEETING

         The annual meeting of stockholders shall be held each year on a date
and at a time designated by the board of directors. At the meeting, directors
shall be elected and any other proper business may be transacted.

         2.3      SPECIAL MEETING

         A special meeting of the stockholders may be called at any time by the
board of directors, or by the chairman of the board, or by the president.

<PAGE>

         2.4      NOTICE OF STOCKHOLDERS' MEETINGS

         All notices of meetings with stockholders shall be in writing and shall
be sent or otherwise given in accordance with Section 2.5 of these bylaws not
less than ten (10) nor more than ninety (90) days before the date of the meeting
to each stockholder entitled to vote at such meeting. The notice shall specify
the place, date, and hour of the meeting, and, in the case of a special meeting,
the purpose or purposes for which the meeting is called.

         2.5      MANNER OF GIVING NOTICE; AFFIDAVIT OF NOTICE

         Written notice of any meeting of stockholders, if mailed, is given when
deposited in the United States mail, postage prepaid, directed to the
stockholder at his address as it appears on the records of the corporation. An
affidavit of the secretary or an assistant secretary or of the transfer agent of
the corporation that the notice has been given shall, in the absence of fraud,
be prima facie evidence of the facts stated therein.

         2.6      QUORUM

         The holders of a majority of the stock issued and outstanding and
entitled to vote thereat, present in person or represented by proxy, shall
constitute a quorum at all meetings of the stockholders for the transaction of
business except as otherwise provided by statute or by the certificate of
incorporation. If, however, such quorum is not present or represented at any
meeting of the stockholders, then the stockholders entitled to vote thereat,
present in person or represented by proxy, shall have power to adjourn the
meeting from time to time, without notice other than announcement at the
meeting, until a quorum is present or represented. At such adjourned meeting at
which a quorum is present or represented, any business may be transacted that
might have been transacted at the meeting as originally noticed.

         2.7      ADJOURNED MEETING; NOTICE

         When a meeting is adjourned to another time or place, unless these
bylaws otherwise require, notice need not be given of the adjourned meeting if
the time and place thereof are announced at the meeting at which the adjournment
is taken. At the adjourned meeting the corporation may transact any business
that might have been transacted at the original meeting. If the adjournment is
for more than thirty (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.

         2.8      VOTING

         The stockholders entitled to vote at any meeting of stockholders shall
be determined in accordance with the provisions of Section 2.10 of these bylaws,
subject to the provisions of Sections 217 and 218 of the General Corporation Law
of Delaware (relating to voting rights of fiduciaries, pledgors and joint owners
of stock and to voting trusts and other voting agreements).

                                       -2-
<PAGE>

         Except as may be otherwise provided in the certificate of incorporation
or these bylaws, each stockholder shall be entitled to one vote for each share
of capital stock held by such stockholder and stockholders shall not be entitled
to cumulate their votes in the election of directors or with respect to any
matter submitted to a vote of the stockholders.

         2.9      WAIVER OF NOTICE

         Whenever notice is required to be given under any provision of the
General Corporation Law of Delaware or of the certificate of incorporation or
these bylaws, a written waiver thereof, signed 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 a 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. Neither the
business to be transacted at, nor the purpose of, any regular or special meeting
of the stockholders need be specified in any written waiver of notice unless so
required by the certificate of incorporation or these bylaws.

         2.10     RECORD DATE FOR STOCKHOLDER NOTICE; VOTING

         For the purpose of determining the stockholders entitled to notice of
or to vote at any meeting of stockholders or any adjournment thereof, or
entitled to receive payment of any dividend or other distribution or the
allotment of any rights, or entitled to exercise any rights in respect of any
change, conversion, or exchange of stock, or other lawful purpose (other than
the expression of consent to corporate action in writing without a meeting) the
directors may fix, in advance, a record date, which, in the case of a meeting of
stockholders, shall not be more than 60 days nor less than 10 days before the
date of such meeting. If no record date is fixed, the record date for
determining stockholders entitled to notice of or to vote at a meeting of
stockholders shall be at the close of business on the day next preceding the day
on which notice is given, or, if notice is waived, at the close of business on
the day next preceding the day on which the meeting is held and the record date
for determining stockholders for any other purpose pursuant to this Section 2.10
shall be at the close of business on the day on which the board of directors
adopts the resolution relating thereto. A determination of stockholders of
record entitled to notice of or to vote at any meeting of stockholders shall
apply to any adjournment of the meeting; provided, however, that the board of
directors may fix a new record date for the adjourned meeting.

         2.11     PROXIES

         Each stockholder entitled to vote at a meeting of stockholders or to
express consent or dissent to corporate action in writing without a meeting may
authorize another person or persons to act for him by a written proxy, signed
by the stockholder and filed with the secretary of the corporation, but no such
proxy shall be voted or acted upon after three (3) years from its date, unless
the proxy provides for a longer period. A proxy shall be deemed signed if the
stockholder's name is placed on the proxy (whether by manual signature,
typewriting, telegraphic transmission or otherwise) by the

                                       -3-
<PAGE>

stockholder or the stockholder's attorney-in-fact. The revocability of a proxy
that states on its face that it is irrevocable shall be governed by the
provisions of Section 212(e) of the General Corporation Law of Delaware.

         2.12     LIST OF STOCKHOLDERS ENTITLED TO VOTE

         The officer who has charge of the stock ledger of the corporation shall
prepare and make, at least ten (10) days before every meeting of stockholders, a
complete list of the stockholders entitled to vote at the meeting, arranged in
alphabetical order, and showing the address of each stockholder and the number
of shares registered in the name of each stockholder. Such list shall be open to
the examination of any stockholder, for any purpose germane to the meeting,
during ordinary business hours, for a period of at least ten (10) days prior to
the meeting, either at a place within the city where the meeting is to be held,
which place shall be specified in the notice of the meeting, or, if not so
specified, at the place where the meeting is to be held. The list shall also 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.

         2.13     NOMINATIONS AND PROPOSALS

         Subject to the rights of holders of any class or series of stock having
a preference over the Common Stock as to dividends or upon liquidation,

                  (a)     nominations for the election of directors, and

                  (b)     business proposed to be brought before any
                          stockholder meeting

may be made by the board of directors or proxy committee appointed by the board
of directors or by any stockholder entitled to vote in the election of
directors generally if such nomination or business proposed is otherwise proper
business before such meeting. However, any such stockholder may nominate one or
more persons for election as directors at a meeting or propose business to be
brought before a meeting, or both, only if such stockholder has given timely
notice in proper written form of their intent to make such nomination or
nominations or to propose such business. To be timely, such stockholder's
notice must be delivered to or mailed and received at the principal executive
offices of the corporation not less than one hundred twenty (120) calendar days
in advance of the date specified in the corporation's proxy statement released
to stockholders in connection with the previous year's annual meeting of
stockholders; provided, however, that in the event that no annual meeting was
held in the previous year or the date of the annual meeting has been changed by
more than thirty (30) days from the date contemplated at the time of the
previous year's proxy statement, notice by the stockholder to be timely must be
so received a reasonable time before the solicitation is made. To be in proper
form, a stockholder's notice to the secretary shall set forth:

                                       -4-

<PAGE>

                    (i) the name and address of the stockholder who intends
to make the nominations or propose the business and, as the case may be, of
the person or persons to be nominated or of the business to be proposed;

                    (ii) a representation that the stockholder is a holder of
record of stock of the corporation entitled to vote at such meeting and, if
applicable, intends to appear in person or by proxy at the meeting to
nominate the person or persons specified in the notice;

                    (iii) if applicable, a description of all arrangements or
understandings between the stockholder and each nominee and any other person
or persons (naming such person or persons) pursuant to which the nomination
or nominations are to be made by the stockholder;

                    (iv) such other information regarding each nominee or
each matter of business to be proposed by such stockholder as would be
required to be included in a proxy statement filed pursuant to the proxy
rules of the Securities and Exchange Commission had the nominee been
nominated, or intended to be nominated, or the matter been proposed, or
intended to be proposed by the board of directors; and

                    (v) if applicable, the consent of each nominee to serve
as director of the corporation if so elected.

         The chairman of the meeting shall refuse to acknowledge the
nomination of any person or the proposal of any business not made in
compliance with the foregoing procedure.

         2.14     INSPECTORS OF ELECTION

         Before any meeting of stockholders, the board of directors may
appoint an inspector or inspectors of election to act at the meeting or its
adjournment. If no inspector of election is so appointed, then the chairman
of the meeting may, and on the request of any stockholder or a stockholder's
proxy shall, appoint an inspector or inspectors of election to act at the
meeting. The number of inspectors shall be either one (1) or three (3). If
inspectors are appointed at a meeting pursuant to the request of one (1) or
more stockholders or proxies, then the holders of a majority of shares or
their proxies present at the meeting shall determine whether one (1) or three
(3) inspectors are to be appointed. If any person appointed as inspector
fails to appear or fails or refuses to act, then the chairman of the meeting
may, and upon the request of any stockholder or a stockholder's proxy shall,
appoint a person to fill that vacancy.

         Such inspectors shall:

                  (a)      determine the number of shares outstanding and the
voting power of each, the number of shares represented at the meeting, the
existence of a quorum, and the authenticity, validity, and effect of proxies;

                  (b)      receive votes, ballots or consents;

                                     -5-
<PAGE>

                  (c)      hear and determine all challenges and questions in
any way arising in connection with the right to vote;

                  (d)      count and tabulate all votes or consents;

                  (e)      determine when the polls shall close;

                  (f)      determine the result; and

                  (g)      do any other acts that may be proper to conduct
the election or vote with fairness to all stockholders.

                                   ARTICLE III

                                    DIRECTORS

         3.1      POWERS

         Subject to the provisions of the General Corporation Law of Delaware
and any limitations in the certificate of incorporation or these bylaws
relating to action required to be approved by the stockholders or by the
outstanding shares, the business and affairs of the corporation shall be
managed and all corporate powers shall be exercised by or under the direction
of the board of directors.

         3.2      NUMBER OF DIRECTORS

         The authorized number of directors shall be seven (7). This number
may be changed by a duly adopted amendment to the certificate of
incorporation or by an amendment to this bylaw adopted by the vote or written
consent of the holders of a majority of the stock issued and outstanding and
entitled to vote or by resolution of a majority of the board of directors.

         No reduction of the authorized number of directors shall have the
effect of removing any director before that director's term of office expires.

         3.3      ELECTION, QUALIFICATION AND TERM OF OFFICE OF DIRECTORS

         Except as provided in the certificate of incorporation and Section 3.4
of these bylaws, directors shall be elected at each annual meeting of
stockholders to hold office until the next annual meeting. Directors need not be
stockholders unless so required by the certificate of incorporation or these
bylaws, wherein other qualifications for directors may be prescribed. Each
director, including a director elected to fill a vacancy, shall hold office
until his successor is elected and qualified or until his earlier resignation or
removal.

         Elections of directors need not be by written ballot.

                                     -6-
<PAGE>

         3.4      RESIGNATION AND VACANCIES

         Any director may resign at any time upon written notice to the
corporation. When one or more directors so resigns and the resignation is
effective at a future date, a majority of the directors then in office,
including those who have so resigned, shall have 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 this section in the filling of other vacancies.

         Unless otherwise provided in the certificate of incorporation or
these bylaws:

                               (i)  Vacancies and newly created directorships
resulting from any increase in the authorized number of directors elected by
all of the stockholders having the right to vote as a single class may be
filled by a majority of the directors then in office, although less than a
quorum, or by a sole remaining director.

                               (ii) Whenever the holders of any class or
classes of stock or series thereof are entitled to elect one or more
directors by the provisions of the certificate of incorporation, vacancies
and newly created directorships of such class or classes or series may be
filled by a majority of the directors elected by such class or classes or
series thereof then in office, or by a sole remaining director so elected.

         If at any time, by reason of death or resignation or other cause,
the corporation should have no directors in office, then any officer or any
stockholder or an executor, administrator, trustee or guardian of a
stockholder, or other fiduciary entrusted with like responsibility for the
person or estate of a stockholder, may call a special meeting of stockholders
in accordance with the provisions of the certificate of incorporation or
these bylaws, or may apply to the Court of Chancery for a decree summarily
ordering an election as provided in Section 211 of the General Corporation
Law of Delaware.

         If, at the time of filling any vacancy or any newly created
directorship, the directors then in office constitute less than a majority of

the Court of Chancery may, upon application of any stockholder or
stockholders holding at least ten (10) percent of the total number of the
shares at the time outstanding having the right to vote for such directors,
summarily order an election to be held to fill any such vacancies or newly
created directorships, or to replace the directors chosen by the directors

         At all meetings of the board of directors, a majority of the
authorized number of directors shall constitute a quorum for the transaction
of business and the act of a majority of the directors present at any meeting
at which there is a quorum shall be the act of the board of directors, except
as may be otherwise specifically provided by statute or by the certificate of
incorporation. If a quorum is not present at any meeting of the board of
directors, then the directors present thereat may adjourn the meeting from
time to time, without notice other than announcement at the meeting, until a

         3.9      WAIVER OF NOTICE

         Whenever notice is required to be given under any provision of the
General Corporation Law of Delaware or of the certificate of incorporation or

                                     -8-

equivalent to notice. Attendance of a person at a meeting shall constitute a
waiver of notice of such meeting, except when the person attends a 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. Neither the business to be transacted at, nor the purpose of, any
regular or special meeting of the directors, or members of a committee of
directors, need be specified in any written waiver of notice unless so
required by the certificate of incorporation or these bylaws.

         3.10     ADJOURNED MEETING; NOTICE

such loan, guaranty or assistance may reasonably be expected to benefit the
corporation. The loan, guaranty or other assistance may be with or without
interest and may be unsecured, or secured in such manner as the board of
directors shall approve, including, without limitation, a pledge of shares of
stock of the corporation. Nothing contained in this section shall be deemed
to deny, limit or restrict the powers of guaranty or warranty of the
corporation at common law or under any statute.

place of any such absent or disqualified member. Any such committee, to the
extent provided in the resolution of the board of directors or in the bylaws
of the corporation, shall have and may exercise all the powers and 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 that may require it; but no such committee shall have the power
or authority to (i) amend the certificate of incorporation (except that a
committee may, to the extent authorized in the resolution or resolutions
providing for the issuance of shares of stock adopted by the board of
directors as provided in Section 151(a) of the General Corporation Law of
Delaware, fix any of the preferences or rights of such shares relating to
dividends, redemption, dissolution, any distribution of assets of the
corporation or the conversion into, or the exchange of such shares for,
shares of any other class or classes or any other series of the

                                     -10-

authorize the issuance of stock, or to adopt a certificate of ownership and
merger pursuant to Section 253 of the General Corporation Law of Delaware.

         4.2      COMMITTEE MINUTES

(quorum), Section 3.9 (waiver of notice), Section 3.10 (adjournment and
notice of adjournment), and Section 3.11 (action without a meeting), with
such changes in the context of those bylaws as are necessary to substitute
the committee and its members for the board of directors and its members;
provided, however, that the time of regular meetings of committees may also
be called by resolution of the board of directors and that notice of special
meetings of committees shall also be given to all alternate members, who
shall have the right to attend all meetings of the committee. The board of

permitted by the General Corporation Law of Delaware, indemnify each of its
directors and officers against expenses (including attorneys' fees), judgments,
fines, settlements, and other amounts actually and reasonably incurred in
connection with any proceeding, arising by reason of the fact that such person

"director" or "officer" of the corporation includes any person (i) who is or was
a director or officer of the corporation, (ii) who is or was serving at the
request of the corporation as a director or officer of another corporation,
partnership, joint venture, trust or other enterprise, or (iii) who was a

         The corporation shall have the power, to the extent and in the manner
permitted by the General Corporation Law of Delaware, to indemnify each of its

in any such capacity, or arising out of his status as such, whether or not the
corporation would have the power to indemnify him against such liability under
the provisions of the General Corporation Law of Delaware.

shall, upon written demand under oath stating the purpose thereof, have the
right during the usual hours for business to inspect for any proper purpose the
corporation's stock ledger, a list of its stockholders, and its other books and
records and to make copies or extracts therefrom. A proper purpose shall mean a
purpose reasonably related to such person's interest as a stockholder. In every
instance where an attorney or other agent is the person who seeks the right to
inspection, the demand under oath shall be accompanied by a power of attorney or
such other writing that authorizes the attorney or other agent to so act on
behalf of the stockholder. The demand under oath shall be directed to the
corporation at its registered office in Delaware or at its principal place of
business.

         7.2      INSPECTION BY DIRECTORS

is hereby vested with the exclusive jurisdiction to determine whether a director
is entitled to the inspection sought. The Court may summarily order the
corporation to permit the director to inspect any and all books and records, the
stock ledger, and the stock list and to make copies or extracts therefrom. The
Court may, in its discretion, prescribe any limitations or conditions with
reference to the inspection, or award such other and further relief as the Court
may deem just and proper.

in the name of this corporation. The authority granted herein may be exercised
either by such person directly or by any other person authorized to do so by

         8.1      CHECKS

         From time to time, the board of directors shall determine by resolution

shall sign or endorse those instruments.

         8.2      EXECUTION OF CORPORATE CONTRACTS AND INSTRUMENTS

         The board of directors, except as otherwise provided in these bylaws,
may authorize any officer or officers, or agent or agents, to enter into any

corporation; such authority may be general or confined to specific instances.
Unless so authorized or ratified by the board of directors or within the agency
power of an officer, no officer, agent or employee shall have any power or
authority to bind the corporation by any contract or engagement or to pledge its
credit or to render it liable for any purpose or for any amount.

         8.3      STOCK CERTIFICATES; PARTLY PAID SHARES

         The shares of the corporation shall be represented by certificates,
provided that the board of directors of the corporation may provide by
resolution or resolutions that some or all of any or all classes or series of
its stock shall be uncertificated shares. Any such resolution shall not apply to
shares represented by a certificate until such certificate is surrendered to the
corporation. Notwithstanding the adoption of such a resolution by the board of
directors, every holder of stock represented by certificates and upon request
every holder of uncertificated shares shall be entitled to have a certificate
signed by, or in the name of the corporation by the chairman or vice-chairman of
the board of directors, or the president or vice-president, and by the treasurer
or an assistant treasurer, or the secretary or an assistant secretary of such
corporation representing the number of shares registered in certificate form.
Any or all of the signatures on the certificate may be a facsimile. In case any
officer, transfer agent or registrar who has signed or whose facsimile signature
has been placed upon a certificate has ceased to be such officer, transfer agent
or registrar before such certificate is issued, it may be issued by the
corporation with the same effect as if he were such officer, transfer agent or
registrar at the date of issue.

         The corporation may issue the whole or any part of its shares as partly
paid and subject to call for the remainder of the consideration to be paid
therefor. Upon the face or back of each stock certificate issued to represent

the case of uncertificated partly paid shares, the total amount of the
consideration to be paid therefor and the amount paid thereon shall be stated.
Upon the declaration of any dividend on fully paid shares, the corporation shall
declare a dividend upon partly paid shares of the same class, but only upon the
basis of the percentage of the consideration actually paid thereon.

         8.4      SPECIAL DESIGNATION ON CERTIFICATES

         If the corporation is authorized to issue more than one class of stock
or more than one series of any class, then the powers, the designations, the
preferences, and the relative, participating, optional or other special rights
of each class of stock or series thereof and the qualifications, limitations or
restrictions of such preferences and/or rights shall be set forth in full or
summarized on the face or back of the certificate that the corporation shall
issue to represent such class or series of stock; provided, however, that,
except as otherwise provided in Section 202 of the General Corporation Law of
Delaware, in lieu of the foregoing requirements there may be set forth on the
face or back of the certificate that the corporation shall issue to represent
such class or series of stock a statement that the corporation will furnish
without charge to each stockholder who so requests the powers, the designations,
the preferences, and the relative, participating, optional or other special
rights of each class of stock or series thereof and the qualifications,
limitations or restrictions of such preferences and/or rights.

         8.5      LOST CERTIFICATES

         Except as provided in this Section 8.5, no new certificates for shares
shall be issued to replace a previously issued certificate unless the latter is
surrendered to the corporation and cancelled at the same time. The corporation
may issue a new certificate of stock or uncertificated shares in the place of
any certificate theretofore issued by it, alleged to have been lost, stolen or
destroyed, and the corporation may require the owner of the lost, stolen or
destroyed certificate, or his legal representative, to give the corporation a
bond sufficient to indemnify it against any claim that may be made against it on
account of the alleged loss, theft or destruction of any such certificate or the
issuance of such new certificate or uncertificated shares.

construction, and definitions in the Delaware General Corporation Law shall

the singular, and the term "person" includes both a corporation and a natural
person.

directors of the corporation that the corporation should be dissolved, the
board, after the adoption of a resolution to that effect by a majority of the

Corporation Law of Delaware. Upon such consent's becoming effective in
accordance with Section 103 of the General Corporation Law of Delaware, the
corporation shall be dissolved. If the consent is signed by an attorney, then
the original power of attorney or a photocopy thereof shall be attached to and
filed with the consent. The consent filed with the Secretary of State shall have
attached to it the affidavit of the secretary or some other officer of the
corporation stating that the consent has been signed by or on behalf of all the
stockholders entitled to vote on a dissolution; in addition, there shall be
attached to the consent a certification by the secretary or some other officer
of the corporation setting forth the names and residences of the directors and

                  (a)      at any meeting held for the election of directors the
stockholders are so divided that they have failed to elect successors to
directors whose terms have expired or would have expired upon qualification of
their successors; or

                  (b)      the business of the corporation is suffering or is
threatened with irreparable injury because the directors are so divided
respecting the management of the affairs of the corporation that the required
vote for action by the board of directors cannot be obtained and the
stockholders are unable to terminate this division; or

                  (c)      the corporation has abandoned its business and has
failed within a reasonable time to take steps to dissolve, liquidate or
distribute its assets.

         11.2     DUTIES OF CUSTODIAN

         The custodian shall have all the powers and title of a receiver
appointed under Section 291 of the General Corporation Law of Delaware, but the
authority of the custodian shall be to continue the business of the corporation
and not to liquidate its affairs and distribute its assets, except when the
Court of Chancery otherwise orders and except in cases arising under Sections
226(a)(3) or 352(a)(2) of the General Corporation Law of Delaware.

                        INTEGRATED TELECOM EXPRESS, INC.

                             (Subject to Adjustment)

         THIS CERTIFIES THAT, for value received, Intel Corporation, a

entitled, subject to the terms and conditions of this Warrant, including the

thousand two hundred eighty-six (714,286) shares of Warrant Stock of the
Company at a price per share of three dollars and fifty cents ($3.50) (the

that certain Series A Preferred Stock and Warrant Purchase Agreement, dated

days ending immediately prior to the applicable date of valuation and (ii)
the number of shares of Common Stock into which each of shares of Series A
Preferred is convertible at the time of such exercise;

                                       1

<PAGE>

                  (b)      If the Common Stock is actively traded
over-the-counter, the Fair Market Value shall be deemed to be the product of:
(i) the average of the closing bid and asked prices of the Common Stock over
the ten (10) trading-day period ending immediately prior to the applicable
date of valuation and (ii) the number of shares of Common Stock into which
each of shares of Series A Preferred is convertible at the time of such
exercise;

                  (c)      If there is no active public market for the Common
Stock, the Fair Market Value shall be the value thereof, as agreed upon by
the Company and the Holder; PROVIDED, HOWEVER, that if the Company and the
Holder cannot agree on such value, such value shall be determined by an
independent valuation firm experienced in valuing businesses such as the
Company and jointly selected in good faith by the Company and the Holder.
Fees and expenses of the valuation firm shall be paid by the Company.

any other securities at any time receivable or issuable upon exercise of this
Warrant.

2.                EXERCISE OF WARRANT.

         2.1.     PAYMENT. Subject to compliance with the terms and
conditions of this Warrant and applicable securities laws, this Warrant may
be exercised, in whole or in part at any time or from time to time, on or
before the Expiration Date by the delivery (including, without limitation,
delivery by facsimile) of the form of Notice of Exercise attached hereto as
EXHIBIT 1 (the "NOTICE OF EXERCISE") duly executed by the Holder, at the
principal office of the Company, surrendering:

                  (a) this Warrant at the principal office of the Company, and

                                       2

<PAGE>

                  (b) payment, (i) in cash, by check or by wire transfer,
(ii) by cancellation by the Holder of any indebtedness of the Company to the
Holder or (iii) by any combination of (i) and (ii), of an amount equal to the
product obtained by multiplying the number of shares of Warrant Stock being
purchased upon such exercise by the then effective Purchase Price (the
"EXERCISE AMOUNT"), except that if the Holder is subject to HSR Act
Restrictions (as defined in Section 2.5 below), the Exercise Amount shall be
paid to the Company within five (5) business days after the termination of
all HSR Act Restrictions.

         2.2.     NET ISSUE EXERCISE. In lieu of the payment methods set
forth in Section 2.1(b) above, the Holder may elect to exchange all or some
of the Warrant for shares of Warrant Stock equal to the value of the amount
of the Warrant being exchanged on the date of exchange. If the Holder elects
to exchange this Warrant as provided in this Section 2.2, the Holder shall
tender to the Company the Warrant for the amount being exchanged, along with
written notice of the Holder's election to exchange some or all of the
Warrant, and the Company shall issue to the Holder the number of shares of
the Warrant Stock computed using the following formula:

                  X = Y (A-B)
                      -------
                         A

                  Where:

                  X = the number of shares of Warrant Stock to be issued to the
                  Holder;

                  Y = the number of shares of Warrant Stock purchasable under
                  the amount of the Warrant being exchanged (as adjusted to the
                  date of such calculation);

                  A = the Fair Market Value of one share of Warrant Stock; and

                  B = the Purchase Price (as adjusted to the date of such
                  calculation).

                  All references herein to an "exercise" of the Warrant shall
include an exchange pursuant to this Section 2.2. Upon receipt of a written
notice of the Company's intention to raise capital by selling shares of
Common Stock in an IPO (the "IPO NOTICE"), which notice shall be delivered to
the Holder at least thirty (30) days before the anticipated date of the
filing with the SEC, the Holder shall promptly notify the Company whether or
not the Holder will exercise this Warrant pursuant to this Section 2.2 prior
to consummation of the IPO. Notwithstanding whether or not an IPO Notice has
been delivered to the Holder or any other provision of this Warrant to the
contrary, if the Holder decides to exercise this Warrant while a registration
statement is on file with the SEC in connection with the IPO, this Warrant
shall be deemed exercised on the consummation of the IPO and the Fair Market
Value of a share of Warrant Stock will be the price at which one share of
Common Stock was sold to the public in the IPO. If the Holder has elected to
exercise this Warrant pursuant to this Section 2.2 while a registration
statement is on file with the SEC in connection with an IPO and the IPO is
not consummated, then the Holder's exercise of this Warrant shall not be
effective unless the Holder confirms in writing the Holder's intention to go
forward with the exercise of this Warrant.

<PAGE>

         2.3.     "EASY SALE" EXERCISE. In lieu of the payment methods set
forth in Section 2.1(b) above, when permitted by law and applicable
regulations (including Nasdaq and NASD rules), the Holder may pay the
Purchase Price through a "same day sale" commitment from the Holder (and if
applicable a broker-dealer that is a member of the National Association of
Securities Dealers (an "NASD Dealer")), whereby the Holder irrevocably elects
to exercise this Warrant and to convert the Warrant Shares receivable into
shares of Common Stock and to sell a portion of the shares of Common Stock so
purchased to pay for the Purchase Price and the Holder (or, if applicable,
the NASD Dealer) commits upon sale (or, in the case of the NASD Dealer, upon
receipt) of such shares to forward the Purchase Price directly to the Company.

         2.4.     STOCK CERTIFICATES; FRACTIONAL SHARES. As soon as
practicable on or after any date of exercise of this Warrant pursuant to this
Section 2, the Company shall issue and deliver to the Person or Persons
entitled to receive the same a certificate or certificates for the number of
whole shares of Warrant Stock issuable upon such exercise, together with cash
in lieu of any fraction of a share equal to such fraction of the current Fair
Market Value of one whole share of Common Stock as of the date of exercise of
this Warrant. No fractional shares or scrip representing fractional shares
shall be issued upon an exercise of this Warrant.

         2.5.     HSR ACT. The Company hereby acknowledges that exercise of
this Warrant by the Holder may subject the Company or the Holder to the
filing requirements of the HSR Act and that the Holder may be prevented from
exercising this Warrant until the expiration or early termination of all
waiting periods imposed by the HSR Act ("HSR ACT RESTRICTIONS"). If on or
before the Expiration Date the Holder has sent a Notice of Exercise to the
Company and the Holder has not been able to complete the exercise of this
Warrant prior to the Expiration Date because of HSR Act Restrictions, the
Holder shall be entitled to complete the process of exercising this Warrant
in accordance with the procedures contained herein within five (5) business
days following termination of the HSR Act Restrictions.

         2.6.     PARTIAL EXERCISE; EFFECTIVE DATE OF EXERCISE. In case of
any partial exercise of this Warrant, the Company shall cancel this Warrant
upon surrender hereof and shall execute and deliver a new Warrant of like
tenor and date for the balance of the shares of Warrant Stock purchasable
hereunder. The partial exercise of this Warrant shall be exercisable in units
of a minimum of 100,000 shares. This Warrant shall be deemed to have been
exercised immediately prior to the close of business on the date of its
surrender for exercise as provided above. However, if the Holder is subject
to HSR Act filing requirements, this Warrant shall be deemed to have been
exercised on the date immediately following the date of the expiration of all
HSR Act Restrictions. The Person entitled to receive the shares of Warrant
Stock issuable upon exercise of this Warrant shall be treated for all
purposes as the holder of record of such shares as of the close of business
on the date the Holder is deemed to have exercised this Warrant.

3.       VALID ISSUANCE; TAXES. All shares of Warrant Stock issued upon the
exercise of this Warrant shall be validly issued, fully paid and
non-assessable, and the Company shall pay all taxes and other governmental
charges that may be imposed in respect of the issue or delivery thereof;
provided, however, that the Company shall not be required to pay any tax or
other charge imposed in connection with any transfer involved in the issuance
of any certificate for shares of Warrant Stock in any name other than that of
the Registered Holder of this Warrant,

                                       4

<PAGE>

and in such case the Company shall not be required to issue or deliver any
stock certificate or security until such tax or other charge has been paid,
or it has been established to the Company's reasonable satisfaction that no
tax or other charge is due.

4.       ADJUSTMENT OF PURCHASE PRICE AND NUMBER OF SHARES. The number of
shares of Warrant Stock issuable upon exercise of this Warrant (or any shares
of stock or other securities or property receivable or issuable upon exercise
of this Warrant) and the Purchase Price are subject to adjustment upon
occurrence of any of the following events:

         4.1.     ADJUSTMENT FOR STOCK SPLITS, STOCK SUBDIVISIONS OR
COMBINATIONS OF SHARES. The Purchase Price shall be proportionally decreased
and the number of shares of Warrant Stock issuable upon exercise of this
Warrant (or any shares of stock or other securities at the time issuable upon
exercise of this Warrant) shall be proportionally increased to reflect any
stock split or subdivision of the Warrant Stock or Common Stock. The Purchase
Price of this Warrant shall be proportionally increased and the number of
shares of Warrant Stock issuable upon exercise of this Warrant (or any shares
of stock or other securities at the time issuable upon exercise of this
Warrant) shall be proportionally decreased to reflect any combination of the
Warrant Stock or Common Stock.

         4.2.     ADJUSTMENT FOR DIVIDENDS OR DISTRIBUTIONS OF STOCK OR OTHER
SECURITIES OR PROPERTY. If the Company shall make or issue, or shall fix a
record date for the determination of eligible holders entitled to receive, a
dividend or other distribution with respect to the Warrant Stock (or any
shares of stock or other securities at the time issuable upon exercise of the
Warrant) or Common Stock payable in (a) securities of the Company or (b)
assets (excluding cash dividends paid or payable solely out of retained
earnings), then, in each such case, the Holder of this Warrant on exercise
hereof at any time after the consummation, effective date or record date of
such dividend or other distribution, shall receive, in addition to the shares
of Warrant Stock (or such other stock or securities) issuable on such
exercise prior to such date, and without the payment of additional
consideration therefor, the securities or such other assets of the Company to
which such Holder would have been entitled upon such date if such Holder had
exercised this Warrant on the date hereof and had thereafter, during the
period from the date hereof to and including the date of such exercise,
retained such shares or all other additional stock available by it as
aforesaid during such period giving effect to all adjustments called for by
this Section 4.

         4.3.     RECLASSIFICATION. If the Company, by reclassification of
securities or otherwise, shall change any of the securities as to which
purchase rights under this Warrant exist into the same or a different number
of securities of any other class or classes, this Warrant shall thereafter
represent the right to acquire such number and kind of securities as would
have been issuable as the result of such change with respect to the
securities that were subject to the purchase rights under this Warrant
immediately prior to such reclassification or other change and the Purchase
Price therefor shall be appropriately adjusted, all subject to further
adjustment as provided in this Section 3. No adjustment shall be made
pursuant to this Section 3.3 upon any conversion or redemption of the Warrant
Stock which is the subject of Section 3.5.

                                       5

<PAGE>

         4.4.     ADJUSTMENT FOR CAPITAL REORGANIZATION, MERGER OR
CONSOLIDATION. In case of any reorganization of the capital stock of the
Company (other than a combination, reclassification, exchange or subdivision
of shares otherwise provided for herein), or any merger or consolidation of
the Company with or into another Person, or the sale of all or substantially
all the assets of the Company then, and in each such case, as a part of such
reorganization, merger, consolidation, sale or transfer, lawful provision
shall be made so that the Holder of this Warrant shall thereafter be entitled
to receive upon exercise of this Warrant, during the period specified herein
and upon payment of the Purchase Price then in effect, the number of shares
of stock or other securities or property of the successor Person resulting
from such reorganization, merger, consolidation, sale or transfer that a
holder of the shares deliverable upon exercise of this Warrant (assuming
conversion of all Warrant Stock to Common Stock) would have been entitled to
receive in such reorganization, consolidation, merger, sale or transfer if
this Warrant (and the Warrant Stock receivable had been converted to Common
Stock) had been exercised immediately before such reorganization, merger,
consolidation, sale or transfer, all subject to further adjustment as
provided in this Section 3. The foregoing provisions of this Section 3.4
shall similarly apply to successive reorganizations, consolidations, mergers,
sales and transfers and to the stock or securities of any other Person that
are at the time receivable upon the exercise of this Warrant. If the
per-share consideration payable to the Holder hereof for shares in connection
with any such transaction is in a form other than cash or marketable
securities, then the value of such consideration shall be determined in good
faith by the Company's Board of Directors. In all events, appropriate
adjustment (as determined in good faith by the Company's Board of Directors)
shall be made in the application of the provisions of this Warrant with
respect to the rights and interests of the Holder after the transaction, to
the end that the provisions of this Warrant shall be applicable after that
event, as near as reasonably may be, in relation to any shares or other
property deliverable after that event upon exercise of this Warrant.

         4.5.     CONVERSION OF WARRANT STOCK. If all or any portion of the
authorized and outstanding shares of Warrant Stock are redeemed or converted
or reclassified into other securities or property pursuant to the Company's
Articles of Incorporation or otherwise, or the Warrant Stock otherwise ceases
to exist, then, in such case, the Holder of this Warrant, upon exercise
hereof at any time after the date on which the Warrant Stock is so redeemed
or converted, reclassified or ceases to exist (the "TERMINATION DATE"), shall
receive, in lieu of the number of shares of Warrant Stock that would have
been issuable upon such exercise immediately prior to the Termination Date,
the shares of Common Stock that would have been received if this Warrant had
been exercised in full and the Warrant Stock received thereupon had been
simultaneously converted immediately prior to the Termination Date, all
subject to further adjustment as provided in this Warrant. Additionally, the
Purchase Price shall be immediately adjusted to equal the quotient obtained
by dividing (a) the aggregate Purchase Price of the maximum number of shares
of Warrant Stock for which this Warrant was exercisable immediately prior to
the Termination Date by (b) the number of shares of Common Stock for which
this Warrant is exercisable immediately after the Termination Date, all
subject to further adjustment as provided herein.

5.       CERTIFICATE AS TO ADJUSTMENTS. In each case of any adjustment in the
Purchase Price, or number or type of shares issuable upon exercise of this
Warrant, the Chief Financial Officer or Controller of the Company shall
compute such adjustment in accordance

                                       6

<PAGE>

with the terms of this Warrant and prepare a certificate setting forth such
adjustment and showing in detail the facts upon which such adjustment is
based, including a statement of the adjusted Purchase Price. The Company
shall promptly send (by facsimile and by either first class mail, postage
prepaid or overnight delivery) a copy of each such certificate to the Holder.

6.       LOSS OR MUTILATION. Upon receipt of evidence reasonably satisfactory
to the Company of the ownership of and the loss, theft, destruction or
mutilation of this Warrant, and of indemnity reasonably satisfactory to it,
and (in the case of mutilation) upon surrender and cancellation of this
Warrant, the Company shall execute and deliver in lieu thereof a new Warrant
of like tenor as the lost, stolen, destroyed or mutilated Warrant.

7.       RESERVATION OF WARRANT STOCK. The Company hereby covenants that at
all times there shall be reserved for issuance and delivery upon exercise of
this Warrant such number of shares of Warrant Stock, Common Stock or other
shares of capital stock of the Company as are from time to time issuable upon
exercise of this Warrant, and, from time to time, will take all steps
necessary to amend its Articles of Incorporation to provide sufficient
reserves of shares of Warrant Stock issuable upon exercise of this Warrant
and Common Stock issuable upon conversion of the Warrant Stock. All such
shares shall be duly authorized, and when issued upon such exercise, shall be
validly issued, fully paid and non-assessable, free and clear of all liens,
security interests, charges and other encumbrances or restrictions on sale
and free and clear of all preemptive rights, except encumbrances or
restrictions arising under federal or state securities laws. Issuance of this
Warrant shall constitute full authority to the Company's officers who are
charged with the duty of executing stock certificates to execute and issue
the necessary certificates for shares of Warrant Stock upon the exercise of
this Warrant and for shares of Common Stock upon conversion of Warrant Stock.

8.       TRANSFER AND EXCHANGE. Subject to the terms and conditions of this
Warrant and compliance with all applicable securities laws, this Warrant and
all rights hereunder may be transferred, to any individual, corporation,
partnership, trust, unincorporated organization or any other entity or
organization not in direct competition with the Company, in whole or in part,
on the books of the Company maintained for such purpose at the principal
office of the Company referred to above, by the Registered Holder hereof in
person, or by duly authorized attorney, upon surrender of this Warrant
properly endorsed and upon payment of any necessary transfer tax or other
governmental charge imposed upon such transfer. Whether or not a proposed
transferee is a direct competitor of the Company will be determined in good
faith by the Board of Directors. Upon any permitted partial transfer, the
Company will issue and deliver to the Registered Holder a new Warrant or
Warrants with respect to the shares of Warrant Stock not so transferred. Each
taker and holder of this Warrant, by taking or holding the same, consents and
agrees that when this Warrant shall have been so endorsed, the Person in
possession of this Warrant may be treated by the Company, and all other
Persons dealing with this Warrant, as the absolute owner hereof for any
purpose and as the Person entitled to exercise the rights represented hereby,
any notice to the contrary notwithstanding; PROVIDED, HOWEVER, that until a
transfer of this Warrant is duly registered on the books of the Company, the
Company may treat the Registered Holder hereof as the owner for all purposes.

9.       RESTRICTIONS ON TRANSFER. The Holder, by acceptance hereof, agrees
that, absent an effective registration statement filed with the SEC under the
Securities Act of 1933, as amended (the "1933 ACT"), covering the disposition
or sale of this Warrant or the Warrant Stock issued or issuable upon exercise
hereof or the Common Stock issuable upon conversion of Warrant Stock, as the
case may be, and registration or qualification under applicable state
securities laws, such Holder will not sell, transfer, pledge, or hypothecate
any or all such Warrants, Warrant Stock, or Common Stock, as the case may be,
unless either (a) the Company has received an opinion of counsel, in form and
substance reasonably satisfactory to the Company, to the effect that such
registration is not required in connection with such disposition or (b) the
sale of such securities is made pursuant to SEC Rule 144.

10.      COMPLIANCE WITH SECURITIES LAWS. By acceptance of this Warrant, the
Holder hereby represents, warrants and covenants: (a) that any shares of
stock purchased upon exercise of this Warrant shall be acquired for
investment only and not with a view to, or for sale in connection with, any
distribution thereof; (b) that the Holder has had such opportunity as such
Holder has deemed adequate to obtain from representatives of the Company such
information as is necessary to permit the Holder to evaluate the merits and
risks of its investment in the Company; (c) that the Holder is able to bear
the economic risk of holding such shares as may be acquired pursuant to the
exercise of this Warrant for an indefinite period; (d) that the Holder has
such knowledge and experience in financial and business matters that it is
capable of evaluating the merits and risks of the purchase of this Warrant
and the shares purchasable pursuant to the terms of this Warrant and of
protecting its interests in connection therewith; (e) that the Holder is an
accredited investor within the meaning of Rule 501 of Regulation D,
promulgated under the 1933 Act, as presently in effect; (f) that the Holder
understands that the shares of stock acquired pursuant to the exercise of
this Warrant will not be registered under the 1933 Act (unless otherwise
required pursuant to exercise by the Holder of the registration rights, if
any, previously granted to the Registered Holder) and will be "restricted
securities" within the meaning of SEC Rule 144 and that the exemption from
registration under Rule 144 will not be available for at least one year from
the date of exercise of this Warrant, subject to any special treatment by the
SEC for exercise of this Warrant pursuant to Section 2.2, and even then will
not be available unless a public market then exists for the stock, adequate
information concerning the Company is then available to the public, and other
terms and conditions of Rule 144 are complied with; and (g) that all stock
certificates representing shares of stock issued to the Holder upon exercise
of this Warrant or upon conversion of such shares may have affixed thereto a
legend substantially in the following form:

         THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE
         SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), OR UNDER THE SECURITIES
         LAWS OF ANY STATE. THESE SECURITIES ARE SUBJECT TO RESTRICTIONS ON
         TRANSFERABILITY AND RESALE AND MAY NOT BE TRANSFERRED OR RESOLD EXCEPT
         AS PERMITTED UNDER THE ACT AND THE APPLICABLE STATE SECURITIES LAWS,
         PURSUANT TO REGISTRATION OR EXEMPTION THEREFROM. INVESTORS SHOULD BE
         AWARE THAT THEY MAY BE REQUIRED TO BEAR THE FINANCIAL RISKS OF THIS
         INVESTMENT FOR AN INDEFINITE PERIOD OF TIME. THE ISSUER OF THESE
         SECURITIES MAY REQUIRE AN OPINION OF COUNSEL IN FORM AND SUBSTANCE
         SATISFACTORY TO THE ISSUER TO THE EFFECT THAT ANY PROPOSED TRANSFER OR
         RESALE IS IN COMPLIANCE WITH THE ACT AND ANY APPLICABLE STATE
         SECURITIES LAWS.

11.      NO RIGHTS OR LIABILITIES AS SHAREHOLDERS. This Warrant shall not
entitle the Holder to any voting rights or other rights as a shareholder of
the Company. In the absence of affirmative action by such Holder to purchase
Warrant Stock by exercise of this Warrant or Common Stock upon conversion
thereof, no provisions of this Warrant, and no enumeration herein of the
rights or privileges of the Holder hereof shall cause such Holder hereof to
be a shareholder of the Company for any purpose.

12.      REGISTRATION RIGHTS. All shares of Common Stock issuable upon
conversion of the shares of Warrant Stock issuable upon exercise of this
Warrant shall be "Registrable Securities" or such other definition of
securities entitled to registration rights pursuant to the Shareholders'
Agreement, dated as of the date hereof, between the Company and the investors
listed on Schedule A thereto, and are entitled, subject to the terms and
conditions of that agreement, to all registration rights granted to holders
of Registrable Securities thereunder.

13.      NOTICES. All notices and other communications from the Company to
the Holder shall be given in accordance with the Purchase Agreement.

convenience in reference only, and shall not be deemed to constitute a part
hereof.

15.      LAW GOVERNING. This Warrant shall be construed and enforced in
accordance with, and governed by, the laws of the State of California.

16.      NO IMPAIRMENT. The Company will not, by amendment of its Articles of
Incorporation or Bylaws, or through reorganization, consolidation, merger,
dissolution, issue or sale of securities, sale of assets or any other
voluntary action, avoid or seek to avoid the observance or performance of any
of the terms of this Warrant, but will at all times in good faith assist in
the carrying out of all such terms and in the taking of all such action as
may be necessary or appropriate in order to protect the rights of the
Registered Holder of this Warrant against impairment. Without limiting the
generality of the foregoing, the Company: (a) will not increase the par value
of any shares of stock issuable upon the exercise of this Warrant above the
amount payable therefor upon such exercise and (b) will take all such action
as may be necessary or appropriate in order that the Company may validly and
legally issue fully paid and non-assessable shares of Warrant Stock upon
exercise of this Warrant.

17.      NOTICES OF RECORD DATE. In case:

         17.1.    the Company shall take a record of the holders of its
Warrant Stock, Common Stock (or other stock or securities at the time
receivable upon the exercise of this Warrant or conversion of Warrant Stock),
for the purpose of entitling them to receive any dividend or other

                                       9

<PAGE>

distribution, or any right to subscribe for or purchase any shares of stock
of any class or any other securities or to receive any other right; or

         17.2.    of any consolidation or merger of the Company with or into
another Person, any capital reorganization of the Company, any
reclassification of the capital stock of the Company, or any conveyance of
all or substantially all of the assets of the Company to another Person in
which holders of the Company's stock are to receive stock, securities or
property of another Person; or

         17.3.    of any voluntary dissolution, liquidation or winding-up of
the Company; or

         17.4.    of any redemption or conversion of all outstanding Common
Stock or Warrant Stock;

then, and in each such case, the Company will mail or cause to be mailed to
the Registered Holder of this Warrant a notice specifying, as the case may
be, (a) the date on which a record is to be taken for the purpose of such
dividend, distribution or right or (b) the date on which such reorganization,
reclassification, consolidation, merger, conveyance, dissolution,
liquidation, winding-up, redemption or conversion is to take place, and the
time, if any is to be fixed, as of which the holders of record of Warrant
Stock, Common Stock (or other stock or securities as at the time are
receivable upon the exercise of this Warrant or conversion of the Warrant
Stock), shall be entitled to exchange their shares of Warrant Stock, Common
Stock (or such other stock or securities), for securities or other property
deliverable upon such reorganization, reclassification, consolidation,
merger, conveyance, dissolution, liquidation or winding-up. Such notice shall
be delivered at least thirty (30) days prior to the date therein specified.

this Warrant is held by a court of competent jurisdiction to be invalid, void
or unenforceable, the remainder of the terms, provisions, covenants and
restrictions of this Warrant shall remain in full force and effect and shall
in no way be affected, impaired or invalidated.

19.      COUNTERPARTS. For the convenience of the parties, any number of
counterparts of this Warrant may be executed by the parties hereto and each
such executed counterpart shall be, and shall be deemed to be, an original
instrument.

20.      SUCCESSORS OR ASSIGNS. The terms of this Warrant shall be binding
upon and shall inure to the benefit of any successors or assigns of the
Company and of the holder or holders hereof and of the Warrant Stock issued
or issuable upon the exercise hereof.

21.      ENTIRE AGREEMENT. This Warrant and the other documents delivered
pursuant hereto constitute the full and entire understanding and agreement
between the parties with regard to the subjects hereof and thereof.

22.      NO INCONSISTENT AGREEMENTS. The Company will not on or after the
date of this Warrant enter into any agreement with respect to its securities
which is inconsistent with the rights granted to the Holder of this Warrant
or otherwise conflicts with the provisions hereof. The rights granted to the
Holder hereunder do not in any way conflict with and are not

                                      10

<PAGE>

inconsistent with the rights granted to holders of the Company's securities
under any other agreements, except rights that have been waived.

23.      SATURDAYS, SUNDAYS AND HOLIDAYS. If the Expiration Date falls on a
Saturday, Sunday or legal holiday, the Expiration Date shall automatically be
