                     CHANGE-OF-CONTROL EMPLOYMENT AGREEMENT

         AGREEMENT by and between Smith International, Inc., a Delaware
corporation (the "Company") and MICHAEL D. PEARCE (the "Executive"), effective
as of the 15th day of May, 2005.

         The Board of Directors of the Company (the "Board"), has determined
that it is in the best interests of the Company and its shareholders to assure
that the Company will have the continued dedication of the Executive,
notwithstanding the possibility, threat or occurrence of a Change of Control (as
defined below) of the Company. The Board believes it is imperative to diminish
the inevitable distraction of the Executive by virtue of the personal
uncertainties and risks created by a pending or threatened Change of Control and
to encourage the Executive's full attention and dedication to the Company
currently and in the event of any threatened or pending Change of Control, and
to provide the Executive with compensation and benefits arrangements upon a
Change of Control which ensure that the compensation and benefits expectations
of the Executive will be satisfied and which are competitive with those of other
corporations. Therefore, in order to accomplish these objectives, the Board has
caused the Company to enter into this Agreement.

         NOW, THEREFORE, IT IS HEREBY AGREED AS FOLLOWS:

         1. Certain Definitions. (a) The "Effective Date", shall mean the first
date during the Change of Control Period (as defined in Section l (b)) on which
a Change of Control (as defined in Section 2) occurs. Anything in this Agreement
to the contrary notwithstanding, if a Change of Control occurs and if the
Executive's employment with the Company is terminated prior to the date on which
the Change of Control occurs, and if it is reasonably demonstrated by the
Executive that such termination of employment (i) was at the request of a third
party who has taken steps reasonably calculated to effect a Change of Control or
(ii) otherwise arose in connection with or anticipation of a Change of Control,
then for all purposes of this Agreement

                                       1
<PAGE>

the "Effective Date" shall mean the date immediately prior to the date of such
termination of employment.

         (b) The "Change of Control Period" shall mean the period commencing on
the date hereof and ending on the third anniversary of the date hereof;
provided, however, that commencing on the date one year after the date hereof,
and on each annual anniversary of such date (such date and each annual
anniversary thereof shall be hereinafter referred to as the "Renewal Date"),
unless previously terminated, the Change of Control Period shall be
automatically extended so as to terminate three years from such Renewal Date,
unless at least 60 days prior to the Renewal Date the Company shall give notice
to the Executive that the Change of Control Period shall not be so extended.

         2. Change of Control. For the purpose of this Agreement, a "Change of
Control" shall mean:

         (a) The acquisition by any individual, entity or group (within the
meaning of Section 13(d)(3) or 14(d)(2) of the Securities Exchange Act of 1934,
as amended (the "Exchange Act")) (a "Person") of beneficial ownership (within
the meaning of Rule 13d-3 promulgated under the Exchange Act) of 20% or more of
either (i) the then outstanding shares of common stock of the Company (the
"Outstanding Company Common Stock") or (ii) the combined voting power of the
then outstanding voting securities of the Company entitled to vote generally in
the election of directors (the "Outstanding Company Voting Securities");
provided, however, that for purposes of this subsection (a), the following
acquisitions shall not constitute a Change of Control: (i) any acquisition
directly from the Company, (ii) any acquisition by the Company, (iii) any
acquisition by any employee benefit plan (or related trust) sponsored or
maintained by the Company or any corporation controlled by the Company or (iv)
any acquisition by any corporation pursuant to a transaction which complies with
clauses (i), (ii) and (iii) of subsection (c) of this Section 2; or

         (b) Individuals who, as of the date hereof, constitute the Board (the
"Incumbent Board") cease for any reason to constitute at least a majority of the
Board; provided, however, that any individual becoming a director subsequent to
the date hereof whose election, or

                                       2
<PAGE>

nomination for election by the Company's shareholders, was approved by a vote of
at least a majority of the directors then comprising the Incumbent Board shall
be considered as though such individual were a member of the Incumbent Board,
but excluding, for this purpose, any such individual whose initial assumption of
office occurs as a result of an actual or threatened election contest with
respect to the election or removal of directors or other actual or threatened
solicitation of proxies or consents by or on behalf of a Person other than the
Board; or

         (c) Consummation of a reorganization, merger or consolidation or sale
or other disposition of all or substantially all of the assets of the Company (a
"Business Combination"), in each case, unless, following such Business
Combination, (i) all or substantially all of the individuals and entities who
were the beneficial owners, respectively, of the Outstanding Company Common
Stock and Outstanding Company Voting Securities immediately prior to such
Business Combination beneficially own, directly or indirectly, more than 60% of,
respectively, the then outstanding shares of common stock and the combined
voting power of the then outstanding voting securities entitled to vote
generally in the election of directors, as the case may be, of the corporation
resulting from such Business Combination (including, without limitation, a
corporation which as a result of such transaction owns the Company or all or
substantially all of the Company's assets either directly or through one or more
subsidiaries) in substantially the same proportions as their ownership,
immediately prior to such Business Combination of the Outstanding Company Common
Stock and Outstanding Company Voting Securities, as the case may be, (ii) no
Person (excluding any corporation resulting from such Business Combination or
any employee benefit plan (or related trust) of the Company or such corporation
resulting from such Business Combination) beneficially owns, directly or
indirectly, 20% or more of, respectively, the then outstanding shares of common
stock of the corporation resulting from such Business Combination or the
combined voting power of the then outstanding voting securities of such
corporation except to the extent that such ownership existed prior to the
Business Combination and (iii) at least a majority of the members of the board
of directors of the corporation resulting from such Business Combination were
members of the Incumbent Board at the time of the execution of the initial
agreement, or of the action of the Board, providing for such Business
Combination; or

                                       3
<PAGE>

         (d) Approval by the shareholders of the Company of a complete
liquidation or dissolution of the Company.

         3. Employment Period. The Company hereby agrees to continue the
Executive in its employ, and the Executive hereby agrees to remain in the employ
of the Company subject to the terms and conditions of this Agreement, for the
period commencing on the Effective Date and ending on the third anniversary of
such date (the "Employment Period").

         4. Terms of Employment. (a) Position and Duties. (i) During the
Employment Period, (A) the Executive's position (including status, offices,
titles and reporting requirements), authority, duties and responsibilities shall
be at least commensurate in all material respects with the most significant of
those held, exercised and assigned at any time during the 120-day period
immediately preceding the Effective Date and (B) the Executive's services shall
be performed at the location where the Executive was employed immediately
preceding the Effective Date or any office or location less than 35 miles from
such location.

         (ii) During the Employment Period, and excluding any periods of
vacation and sick leave to which the Executive is entitled, the Executive agrees
to devote reasonable attention and time during normal business hours to the
business and affairs of the Company and, to the extent necessary to discharge
the responsibilities assigned to the Executive hereunder, to use the Executive's
reasonable best efforts to perform faithfully and efficiently such
responsibilities. During the Employment Period it shall not be a violation of
this Agreement for the Executive to (A) serve on corporate, civic or charitable
boards or committees, (B) deliver lectures, fulfill speaking engagements or
teach at educational institutions and (C) manage personal investments, so long
as such activities do not significantly interfere with the performance of the
Executive's responsibilities as an employee of the Company in accordance with
this Agreement. It is expressly understood and agreed that to the extent that
any such activities have been conducted by the Executive prior to the Effective
Date, the continued conduct of such activities (or the conduct of activities
similar in nature and scope thereto) subsequent to the Effective Date shall not
thereafter be deemed to interfere with the performance of the Executive's
responsibilities to the Company.

                                       4

         (b) Compensation. (i) Base Salary. During the Employment Period, the
Executive shall receive an annual base salary ("Annual Base Salary"), which
shall be paid at a monthly rate, at least equal to twelve times the highest
monthly base salary paid or payable, including any base salary which has been
earned but deferred, to the Executive by the Company and its affiliated
companies in respect of the twelve-month period immediately preceding the month
in which the Effective Date occurs. During the Employment Period, the Annual
Base Salary shall be reviewed no more than 12 months after the last salary
increase awarded to the Executive prior to the Effective Date and thereafter at
least annually. Any increase in Annual Base Salary shall not serve to limit or
reduce any other obligation to the Executive under this Agreement. Annual Base
Salary shall not be reduced after any such increase and the term Annual Base
Salary as utilized in this Agreement shall refer to Annual Base Salary as so
increased. As used in this Agreement, the term "affiliated companies" shall
include any company controlled by, controlling or under common control with the
Company.

         (ii) Annual Bonus. In addition to Annual Base Salary, the Executive
shall be awarded, for each fiscal year ending during the Employment Period, an
annual bonus (the "Annual Bonus") in cash (i) under the Company's Annual
Incentive Plan based upon meeting the targets in the Annual Incentive Plan,
provided that the Executive's target bonus percentage shall be at least equal to
the Executive's target bonus percentage for the fiscal year prior to the
Effective Date or equal to an increase in the target bonus percentage given to
any similarly situated executive after the Effective Date, or, if higher, (ii)
under any annual incentive plan or discretionary award by the Company to
similarly situated executives which is enacted or approved after the Effective
Date. Each such Annual Bonus shall be paid no later than the end of the third
month of the fiscal year next following the fiscal year for which the Annual
Bonus is awarded, unless the Executive shall elect to defer the receipt of such
Annual Bonus.

         (iii) Incentive, Savings and Retirement Plans. During the Employment
Period, the Executive shall be entitled to participate in all incentive, savings
and retirement plans, practices, policies and programs applicable generally to
other peer executives of the Company and its affiliated companies, but in no
event shall such plans, practices, policies and programs provide

                                       5
<PAGE>

the Executive with incentive opportunities (measured with respect to both
regular and special incentive opportunities, to the extent, it any, that such
distinction is applicable), savings opportunities and retirement benefit
opportunities, in each case, less favorable, in the aggregate, than the most
favorable of those provided by the Company and its affiliated companies for the
Executive under such plans, practices, policies and programs as in effect at any
time during the 120-day period immediately preceding the Effective Date or if
more favorable to the Executive, those provided generally at any time after the
Effective Date to other peer executives of the Company and its affiliated
companies.

         (iv) Welfare Benefit Plans. During the Employment Period, the Executive
and/or the Executive's-family, as the case may be, shall be eligible for
participation in and shall receive all benefits under welfare benefit plans,
practices, policies and programs provided by the Company and its affiliated
companies (including, without limitation, medical, prescription, dental,
disability, employee life, group life, accidental death and travel accident
insurance plans and programs) to the extent applicable generally to other peer
executives of the Company and its affiliated companies, but in no event shall
such plans, practices, policies and programs provide the Executive with benefits
which are less favorable, in the aggregate, than the most favorable of such
plans, practices, policies and programs in effect for the Executive at any time
during the 120-day period immediately preceding the Effective Date or, if more
favorable to the Executive, those provided generally at any time after the
Effective Date to other peer executives of the Company and its affiliated
companies.

         (v) Expenses. During the Employment Period, the Executive shall be
entitled to receive prompt reimbursement for all reasonable expenses incurred by
the Executive in accordance with the most favorable policies, practices and
procedures of the Company and its affiliated companies in effect for the
Executive at any time during the 120-day period immediately preceding the
Effective Date or, if more favorable to the Executive, as in effect generally at
any time thereafter with respect to other peer executives of the Company and its
affiliated companies.

                                       6
<PAGE>

         (vi) Fringe Benefits. During the Employment Period, the Executive shall
be entitled to fringe benefits, including, without limitation, tax and financial
planning services, payment of club dues, and, if applicable, use of an
automobile and payment of related expenses, in accordance with the most
favorable plans, practices, programs and policies of the Company and its
affiliated companies in effect for the Executive at any time during the 120-day
period immediately preceding the Effective Date or, if more favorable to the
Executive, as in effect generally at any time thereafter with respect to other
peer executives of the Company and its affiliated companies.

         (vii) Office and Support Staff. During the Employment Period, the
Executive shall be entitled to an office or offices of a size and with
furnishings and other appointments, and to exclusive personal secretarial and
other assistance, at least equal to the most favorable of the foregoing provided
to the Executive by the Company and its affiliated companies at any time during
the 120-day period immediately preceding the Effective Date or, if more
favorable to the Executive, as provided generally at any time thereafter with
respect to other peer executives of the Company and its affiliated companies.

         (viii) Vacation. During the Employment Period, the Executive shall be
entitled to paid vacation in accordance with the most favorable plans, policies,
programs and practices of the Company and its affiliated companies as in effect
for the Executive at any time during the 120-day period immediately preceding
the Effective Date or, if more favorable to the Executive, as in effect
generally at any time thereafter with respect to other peer executives of the
Company and its affiliated companies.

         5. Termination of Employment. (a) Death or Disability. The Executive's
employment shall terminate automatically upon the Executive's death during the
Employment Period. If the Company determines in good faith that the Disability
of the Executive has occurred during the Employment Period (pursuant to the
definition of Disability set forth below), it may give to the Executive written
notice in accordance with Section 12(b) of this Agreement of its intention to
terminate the Executive's employment. In such event, the Executive's employment
with the Company shall terminate effective on the 30th day after receipt of such
notice by the

                                       7
<PAGE>

Executive (the "Disability Effective Date"), provided that, within the 30 days
after such receipt, the Executive shall not have returned to full-time
performance of the Executive's duties. For purposes of this Agreement,
"Disability" shall mean the absence of the Executive from the Executive's duties
with the Company on a full-time basis for 180 consecutive business days as a
result of incapacity due to mental or physical illness which is determined to be
total and permanent by a physician selected by the Company or its insurers and
acceptable to the Executive or the Executive's legal representative.

         (b) Cause. The Company may terminate the Executive's employment during
the Employment Period for Cause. For purposes of this Agreement, "Cause" shall
mean:

         (i) the willful and continued failure of the Executive to perform
         substantially the Executive's duties with the Company or one of its
         affiliates (other than any such failure resulting from incapacity due
         to physical or mental illness), after a written demand for substantial
         performance is delivered to the Executive by the Board or the Chief
         Executive Officer of the Company which specifically identifies the
         manner in which the Board or Chief Executive Officer believes that the
         Executive has not substantially performed the Executive's duties, or

         (ii) the willful engaging by the Executive in illegal conduct or gross
         misconduct which is materially and demonstrably injurious to the
         Company.

         For purposes of this provision, no act or failure to act, on the part
of the Executive, shall be considered "willful" unless it is done, or omitted to
be done, by the Executive in bad faith or without reasonable belief that the
Executive's action or omission was in the best interests of the Company. Any
act, or failure to act, based upon authority given pursuant to a resolution duly
adopted by the Board or upon the instructions of the Chief Executive Officer or
a senior officer of the Company or based upon the advice of counsel for the
Company shall be conclusively presumed to be done, or omitted to be done, by the
Executive in good faith and in the best interests of the Company. The cessation
of employment of the Executive shall not be deemed to be for Cause unless and
until there shall have been delivered to the Executive a copy of a

                                       8
<PAGE>

resolution duly adopted by the affirmative vote of not less than three-quarters
of the entire membership of the Board at a meeting of the Board called and held
for such purpose (after reasonable notice is provided to the Executive and the
Executive is given an opportunity, together with counsel, to be heard before the
Board), finding that, in the good faith opinion of the Board, the Executive is
guilty of the conduct described in subparagraph (i) or (ii) above, and
specifying the particulars thereof in detail.

         (c) Good Reason. The Executive's employment may be terminated by the
Executive for Good Reason. For purposes of this Agreement, "Good Reason" shall
mean:

         (i) the assignment to the Executive of any duties inconsistent in any
         respect with the Executive's position (including status, offices,
         titles and reporting requirements), authority, duties or
         responsibilities as contemplated by Section 4(a) of this Agreement, or
         any other action by the Company which results in a diminution in such
         position, authority, duties or responsibilities, excluding for this
         purpose an isolated, insubstantial and inadvertent action not taken in
         bad faith and which is remedied by the Company promptly after receipt
         of notice thereof given by the Executive;

         (ii) any failure by the Company to comply with any of the provisions of
         Section 4(b) of this Agreement, other than an isolated, insubstantial
         and inadvertent failure not occurring in bad faith and which is
         remedied by the Company promptly after receipt of notice thereof given
         by the Executive;

         (iii) the Company's requiring the Executive to be based at any office
         or location other than as provided in Section 4(a)(i)(B) hereof or the
         Company's requiring the Executive to travel on Company business to a
         substantially greater extent than required immediately prior to the
         Effective Date;

         (iv) any purported termination by the Company of the Executive's
         employment otherwise than as expressly permitted by this Agreement; or

                                       9
<PAGE>

         (v) any failure by the Company to comply with and satisfy Section 11(c)
of this Agreement.

         For purposes of this Section 5(c), any good faith determination of
"Good Reason" made by the Executive shall be conclusive. Anything in this
Agreement to the contrary notwithstanding, a termination by the Executive for
any reason during the 30-day period immediately following the first anniversary
of the Effective Date shall be deemed to be a termination for Good Reason for
all purposes of this Agreement.

         (d) Notice of Termination. Any termination by the Company for Cause, or
by the Executive for Good Reason, shall be communicated by Notice of Termination
to the other party hereto given in accordance with Section 12(b) of this
Agreement. For purposes of this Agreement, a "Notice of Termination" means a
written notice which indicates the specific termination provision in this
Agreement relied upon, (ii) to the extent applicable, sets forth in reasonable
detail the facts and circumstances claimed to provide a basis for termination of
the Executive's employment under the provision so indicated and (iii) if the
Date of Termination (as defined below) is other than the date of receipt of such
notice, specifies the termination date (which date shall be not more than thirty
days after the giving of such notice). The failure by the Executive or the
Company to set forth in the Notice of Termination any fact or circumstance which
contributes to a showing of Good Reason or Cause shall not waive any right of
the Executive or the Company, respectively, hereunder or preclude the Executive
or the Company, respectively, from asserting such fact or circumstance in
enforcing the Executive's or the Company's rights hereunder.

         (e) Date of Termination. "Date of Termination" means (i) if the
Executive's employment is terminated by the Company for Cause, or by the
Executive for Good Reason, the date of receipt of the Notice of Termination or
any later date specified therein, as the case may be, (ii) if the Executive's
employment is terminated by the Company other than for Cause or Disability, the
Date of Termination shall be the date on which the Company notifies the
Executive of such termination and (iii) if the Executive's employment is
terminated by reason of

                                       10
<PAGE>

death or Disability, the Date of Termination shall be the date of death of the
Executive or the Disability Effective Date, as the case may be.

         6. Obligations of the Company upon Termination. (a) Good Reason; Other
Than for Cause, Death or Disability. If, during the Employment Period, the
Company shall terminate the Executive's employment other than for Cause or
Disability or the Executive shall terminate employment for Good Reason:

         (i) the Company shall pay to the Executive in a lump sum in cash within
         30 days after the Date of Termination the aggregate of the following
         amounts:

                   A. the sum of (1) the Executive's Annual Base Salary through
         the Date of Termination to the extent not theretofore paid, (2) the
         product of (x) the higher of (I) the highest Annual Bonus paid to the
         Executive for the last three full fiscal years prior to the Effective
         Date and (II) the Annual Bonus paid or payable, including any bonus or
         portion thereof which has been earned but deferred (and annualized for
         any fiscal year consisting of less than twelve full months or during
         which the Executive was employed for less than twelve full months), for
         the most recently completed fiscal year during the Employment Period,
         if any (such higher amount being referred to as the "Highest Annual
         Bonus") and (y) a fraction, the numerator of which is the number of
         days in the current fiscal year through the Date of Termination, and
         the denominator of which is 365 and (3) any compensation previously
         deferred by the Executive (together with any accrued interest or
         earnings thereon) and any accrued vacation pay, in each case to the
         extent not theretofore paid (the sum of the amounts described in
         clauses (1), (2), and (3) shall be hereinafter referred to as the
         "Accrued Obligations"); and

                   B. the amount equal to the product of (1) three and (2) the
         sum of (x) the Executive's Annual Base Salary and (y) the Highest
         Annual Bonus; and

                                       11
<PAGE>

                   C. an amount equal to the excess of (a) the actuarial
         equivalent of the benefit under any excess or supplemental retirement
         plan in which the Executive participates (the "SERP") which the
         Executive would receive if the Executive's employment continued for
         three years after the Date of Termination assuming for this purpose
         that all accrued benefits are fully vested, and, assuming that the
         Executive's compensation in each of the three years is that required by
         Section 4(b)(i) and Section 4(b)(ii), over (b) the actuarial equivalent
         of the Executive's actual benefit (paid or payable), if any, under the
         SERP as of the Date of Termination;

         (ii) for three years after the Executive's Date of Termination, or such
         longer period as may be provided by the terms of the appropriate plan,
         program, practice or policy, the Company shall continue benefits to the
         Executive and/or the Executive's family at least equal to those which
         would have been provided to them in accordance with the plans,
         programs, practices and policies described in Section 4(b)(iv) of this
         Agreement if the Executive's employment had not been terminated or, if
         more favorable to the Executive, as in effect generally at any time
         thereafter with respect to other peer executives of the Company and its
         affiliated companies and their families, provided, however, that if the
         Executive becomes reemployed with another employer and is eligible to
         receive medical or other welfare benefits under another employer
         provided plan, the medical and other welfare benefits described herein
         shall be secondary to those provided under such other plan during such
         applicable period of eligibility. For purposes of determining
         eligibility (but not the time of commencement of benefits) of the
         Executive for retiree benefits pursuant to such plans, practices,
         programs and policies, the Executive shall be considered to have
         remained employed until three years after the Date of Termination and
         to have retired on the last day of such period;

         (iii) the Company shall, at its sole expense as incurred, provide the
         Executive with outplacement services the scope and provider of which
         shall be selected by the Executive in his sole discretion; and

         (iv) to the extent not theretofore paid or provided, the Company shall
         timely pay or provide to the Executive any other amounts or benefits
         required to be paid or provided or which the Executive is eligible to
         receive under any plan, program, policy or practice or

                                       12
<PAGE>

         contract or agreement of the Company and its affiliated companies (such
         other amounts and benefits shall be hereinafter referred to as the
         "Other Benefits").

         (b) Death. If the Executive's employment is terminated by reason of the
Executive's death during the Employment Period, this Agreement shall terminate
without further obligations to the Executive's legal representatives under this
Agreement, other than for payment of Accrued Obligations and the timely payment
or provision of Other Benefits. Accrued Obligations shall be paid to the
Executive's estate or beneficiary, as applicable, in a lump sum in cash within
30 days of the Date of Termination. With respect to the provision of Other
Benefits, the term Other Benefits as utilized in this Section 6(b) shall
include, without limitation, and the Executive's estate and/or beneficiaries
shall be entitled to receive, benefits at least equal to the most favorable
benefits provided by the Company and affiliated companies to the estates and
beneficiaries of peer executives of the Company and such affiliated companies
under such plans, programs, practices and policies relating to death benefits,
if any, as in effect with respect to other peer executives and their
beneficiaries at any time during the 120-day period immediately preceding the
Effective Date or, if more-favorable to the Executive's estate and/or the
Executive's beneficiaries, as in effect on the date of the Executive's death
with respect to other peer executives of the Company and its affiliated
companies and their beneficiaries.

         (c) Disability. If the Executive's employment is terminated by reason
of the Executive's Disability during the Employment Period, this Agreement shall
terminate without further obligations to the Executive, other than for payment
of Accrued Obligations and the timely payment or provision of Other Benefits.
Accrued Obligations shall be paid to the Executive in a lump sum in cash within
30 days of the Date of Termination. With respect to the provision of Other
Benefits, the term Other Benefits as utilized in this Section 6(c) shall
include, and the Executive shall be entitled after the Disability Effective Date
to receive, disability and other benefits at least equal to the most favorable
of those generally provided by the Company and its affiliated companies to
disabled executives and/or their families in accordance with such plans,
programs, practices and policies relating to disability, if any, as in effect
generally with respect to other peer executives and their families at any time
during the 120-day period immediately preceding the Effective Date or, if more
favorable to the Executive and/or the

                                       13
<PAGE>

Executive's family, as in effect at any time thereafter generally with respect
to other peer executives of the Company and its affiliated companies and their
families.

         (d) Cause; Other than for Good Reason. If the Executive's employment
shall be terminated for Cause during the Employment Period, this Agreement shall
terminate without further obligations to the Executive other than the obligation
to pay to the Executive (x) his Annual Base Salary through the Date of
Termination, (y) the amount of any compensation previously deferred by the
Executive, and (z) Other Benefits, in each case to the extent theretofore
unpaid. If the Executive voluntarily terminates employment during the Employment
Period, excluding a termination for Good Reason, this Agreement shall terminate
without further obligations to the Executive, other than for Accrued Obligations
and the timely payment or provision of Other Benefits. In such case, all Accrued
Obligations shall be paid to the Executive in a lump sum in cash within 30 days
of the Date of Termination.

         7. Non-exclusivity of Rights. Nothing in this Agreement shall prevent
or limit the Executive's continuing or future participation in any plan,
program, policy or practice provided by the Company or any of its affiliated
companies and for which the Executive may qualify, nor, subject to Section
12(f), shall anything herein limit or otherwise affect such rights as the
Executive may have under any contract or agreement with the Company or any of
its affiliated companies. Amounts which are vested benefits or which the
Executive is otherwise entitled to receive under any plan, policy, practice or
program of or any contract or agreement with the Company or any of its
affiliated companies at or subsequent to the Date of Termination shall be
payable in accordance with such plan, policy, practice or program or contract or
agreement except as explicitly modified by this Agreement.

         8. Full Settlement. The Company's obligation to make the payments
provided for in this Agreement and otherwise to perform its obligations
hereunder shall not be affected by any setoff, counterclaim, recoupment, defense
or other claim, right or action which the Company may have against the Executive
or others. In no event shall the Executive be obligated to seek other employment
or take any other action by way of mitigation of the amounts payable to the
Executive under any of the provisions of this Agreement and such amounts shall
not be reduced

                                       14
<PAGE>

whether or not the Executive obtains other employment. The Company agrees to pay
as incurred, to the full extent permitted by law, all legal fees and expenses
which the Executive may reasonably incur as a result of any contest (regardless
of the outcome thereof) by the Company, the Executive or others of the validity
or enforceability of, or liability under, any provision of this Agreement or any
guarantee of performance thereof (including as a result of any contest by the
Executive about the amount of any payment pursuant to this Agreement), plus in
each case interest on any delayed payment at the applicable Federal rate
provided for in Section 7872(f)(2)(A) of the Internal Revenue Code of 1986, as
amended (the "Code").

         9. Certain Additional Payments by the Company.

         (a) Anything in this Agreement to the contrary notwithstanding and
except as set forth below, in the event it shall be determined that any payment
or distribution by the Company or its affiliates to or for the benefit of the
Executive (whether paid or payable or distributed or distributable pursuant to
the terms of this Agreement or otherwise, but determined without regard to any
additional payments required under this Section 9) (a "Payment") would be
subject to excise or other similar tax, or federal income tax above the rate
ordinarily applicable to wages and salaries paid in the ordinary course of
business, whether as a result of the provisions of Sections 280G and 4999 of the
Code, any similar or analogous provisions of any statute or regulation adopted
subsequent to the date hereof, or otherwise, or any interest or penalties are
incurred by the Executive with respect to such tax (such excise tax, other
similar tax or federal income tax, together with any such interest and
penalties, are hereinafter collectively referred to as the "Excise Tax"), then
the Executive shall be entitled to receive an additional payment (a "Gross-Up
Payment") in an amount such that after payment by the Executive of all taxes
(including any interest or penalties imposed with respect to such taxes),
including, without limitation, any income taxes (and any interest and penalties
imposed with respect thereto) and Excise Tax imposed upon the Gross-Up Payment,
the Executive retains an amount of the Gross-Up Payment equal to the Excise Tax
imposed upon the Payments. Notwithstanding the foregoing provisions of this
Section 9(a), if it shall be determined that the Executive is entitled to a
Gross-Up Payment, but that the Payments do not exceed 110% of the greatest
amount (the "Reduced Amount") that could be paid to the Executive such that the
receipt of Payments would

                                       15
<PAGE>

not give rise to any Excise Tax, then no Gross-Up Payment shall be made to the
Executive and the Payments, in the aggregate, shall be reduced to the Reduced
Amount.

         (b) Subject to the provisions of Section 9(c), all determinations
required to be made under this Section 9, including whether and when a Gross-Up
Payment is required and the amount of such Gross-Up Payment and the assumptions
to be utilized in arriving at such determination, shall be made by a certified
public accounting firm as may be designated by the Executive (the "Accounting
Firm") which shall provide detailed supporting calculations both to the Company
and the Executive within 15 business days of the receipt of notice from the
Executive that there has been a Payment, or such earlier time as is requested by
the Company. In the event that the Accounting Firm is serving as accountant or
auditor for the individual, entity or group effecting the Change of Control, the
Executive shall appoint another nationally recognized accounting firm to make
the determinations required hereunder (which accounting firm shall then be
referred to as the Accounting Firm hereunder). All fees and expenses of the
Accounting Firm shall be borne solely by the Company. Any Gross-Up Payment, as
determined pursuant to this Section 9, shall be paid by the Company to the
Executive within five days of the receipt of the Accounting Firm's
determination. Any determination by the Accounting Firm shall be binding upon
the Company and the Executive. As a result of the uncertainty in the application
of Section 4999 of the Code at the time of the initial determination by the
Accounting Firm hereunder, it is possible that Gross-Up Payments which will not
have been made by the Company should have been made ("Underpayment"), consistent
with the calculations required to be made hereunder. In the event that the
Company exhausts its remedies pursuant to Section 9(c) and the Executive
thereafter is required to make a payment of any Excise Tax, the Accounting Firm
shall determine the amount of the Underpayment that has occurred and any such
Underpayment shall be promptly paid by the Company to or for the benefit of the
Executive.

         (c) The Executive shall notify the Company in writing of any claim by
the Internal Revenue Service that, if successful, would require the payment by
the Company of the Gross-Up Payment. Such notification shall be given as soon as
practicable but no later than ten business days after the Executive is informed
in writing of such claim and shall apprise the Company of

                                       16
<PAGE>

the nature of such claim and the date on which such claim is requested to be
paid. The Executive shall not pay such claim prior to the expiration of the
30-day period following the date on which it gives such notice to the Company
(or such shorter period ending on the date that any payment of taxes with
respect to such claim is due). If the Company notifies the Executive in writing
prior to the expiration of such period that it desires to contest such claim,
the Executive shall:

         (i) give the Company any information reasonably requested by the
         Company relating to such claim,

         (ii) take such action in connection with contesting such claim as the
         Company shall reasonably request in writing from time to time,
         including, without limitation, accepting legal representation with
         respect to such claim by an. attorney reasonably selected by the
         Company,

         (iii) cooperate with the Company in good faith in order effectively to
         contest such claim, and

         (iv) permit the Company to participate in any proceedings relating to
         such claim;

provided, however, that the Company shall bear and pay directly all costs and
expenses (including additional interest and penalties) incurred in connection
with such contest and shall indemnify and hold the Executive harmless, on an
after-tax basis, for any Excise Tax or income tax (including interest and
penalties with respect thereto) imposed as a result of such representation and
payment of costs and expenses. Without limitation on the foregoing provisions of
this Section 9(c), the Company shall control all proceedings taken in connection
with such contest and, at its sole option, may pursue or forgo any and all
administrative appeals, proceedings, hearings and conferences with the taxing
authority in respect of such claim and may, at its sole option, either direct
the Executive to pay the tax claimed and sue for a refund or contest the claim
in any permissible manner, and the Executive agrees to prosecute such contest to
a determination before any administrative tribunal, in a court of initial
jurisdiction and in one or more appellate courts, as the Company shall
determine; provided, however, that if the

                                       17
<PAGE>

Company directs the Executive to pay such claim and sue for a refund, the
Company shall advance the amount of such payment to the Executive, on an
interest-free basis and shall indemnify and hold the Executive harmless, on an
after-tax basis, from any Excise Tax or income tax (including interest or
penalties with respect thereto) imposed with respect to such advance or with
respect to any imputed income with respect to such advance; and further provided
that any extension of the statute of limitations relating to payment of taxes
for the taxable year of the Executive with respect to which such contested
amount is claimed to be due is limited solely to such contested amount.
Furthermore, the Company's control of the contest shall be limited to issues
with respect to which a Gross-Up Payment would be payable hereunder and the
Executive shall be entitled to settle or contest, as the case may be, any other
issue raised by the Internal Revenue Service or any other taxing authority.

         (d) If, after the receipt by the Executive of an amount advanced by the
Company pursuant to Section 9(c), the Executive becomes entitled to receive any
refund with respect to such claim, the Executive shall (subject to the Company's
complying with the requirements of Section 9(c)) promptly pay to the Company the
amount of such refund (together with any interest paid or credited thereon after
taxes applicable thereto). If, after the receipt by the Executive of an amount
advanced by the Company pursuant to Section 9(c), a determination is made that
the Executive shall not be entitled to any refund with respect to such claim and
the Company does not notify the Executive in writing of its intent to contest
such denial of refund prior to the expiration of 30 days after such
determination, then such advance shall be forgiven and shall not be required to
be repaid and the amount of such advance shall offset, to the extent thereof,
the amount of Gross-Up Payment required to be paid.

         10. Confidential Information. The Executive shall hold in a fiduciary
capacity for the benefit of the Company all secret or confidential information,
knowledge or data relating to the Company or any of its affiliated companies,
and their respective businesses, which shall have been obtained by the Executive
during the Executive's employment by the Company or any of its affiliated
companies and which shall not be or become public knowledge (other than by acts
by the Executive or representatives of the Executive in violation of this
Agreement). After termination of the Executive's employment with the Company,
the Executive shall not, without

                                       18
<PAGE>

the prior written consent of the Company or as may otherwise be required by law
or legal process, communicate or divulge any such information, knowledge or data
to anyone other than the Company and those designated by it. In no event shall
an asserted violation of the provisions of this Section 10 constitute a basis
for deferring or withholding any amounts otherwise payable to the Executive
under this Agreement.

         11. Successors. (a) This Agreement is personal to the Executive and
without the prior written consent of the Company shall not be assignable by the
Executive otherwise than by will or the laws of descent and distribution. This
Agreement shall inure to the benefit of and be enforceable by the Executive's
legal representatives.

         (b) This Agreement shall inure to the benefit of and be binding upon
the Company and its successors and assigns.

         (c) The Company will require any successor (whether direct or indirect,
by purchase, merger, consolidation or otherwise) to all or substantially all of
the business and/or assets of the Company to assume expressly and agree to
perform this Agreement in the same manner and to the same extent that the
Company would be required to perform it if no such succession had taken place.
As used in this Agreement, "Company" shall mean the Company as hereinbefore
defined and any successor to its business and/or assets as aforesaid which
assumes and agrees to perform this Agreement by operation of law, or otherwise.

         12. Miscellaneous. (a) This Agreement shall be governed by and
construed in accordance with the laws of the State of Texas, without reference
to principles of conflict of laws. The captions of this Agreement are not part
of the provisions hereof and shall have no force or effect. This Agreement may
not be amended or modified otherwise than by a written agreement executed by the
parties hereto or their respective successors and legal representatives.

         (b) All notices and other communications hereunder shall be in writing
and shall be given by hand delivery to the other party or by registered or
certified mail, return receipt requested, postage prepaid, addressed as follows:

Agreement may not be terminated by the Company if it is reasonably demonstrated
by the Executive that such termination (i) was at the request of a third party
who has taken steps reasonably calculated to effect a Change of Control or (ii)
otherwise arose in connection with or anticipation of a Change of Control. From
and after the Effective Date this Agreement shall supersede any other agreement
between the parties with respect to the subject matter hereof.

EXHIBIT 10.1

Ixia

2005 Employee Bonus Plan

(United States)

The 2005 Employee Bonus Plan (“2005 Bonus Plan”) is designed to motivate employees of Ixia (“Ixia”
or the “Company”) and any U.S. subsidiaries and to reward them for their continuing contributions
to the Company’s business if Ixia achieves certain financial results in 2005. The Company believes
that the achievement of these results is essential for the Company’s success and for the continued
growth in shareholder value.

2005 Bonus Plan:

Each Eligible Employee (as defined below) who earns a bonus by virtue of his or her continuing
employment with Ixia will be eligible to receive a quarterly bonus (“Quarterly Bonus”) based on the
Company’s financial performance as measured by the degree of the Company’s attainment of a pre-set,
Board of Directors’ approved, operating income after consideration of the bonus goal for each
calendar quarter during 2005. The impact of acquisitions during the year will be excluded for
bonus calculation purposes.

The quarterly bonuses attributable to an Eligible Employee under the 2005 Bonus Plan for purposes
of the bonus pool in which the Eligible Employee participates will be calculated as a percentage of
such employee’s actual paid year to date earnings, excluding certain compensation and payments
(e.g., reimbursement for moving expenses, bonus payments received for prior period, stock option
compensation, disability benefits, sign-on bonuses, vacation cash-outs, on call pay, and similar
payments).

Eligible Employees:

All full-time and part-time employees of Ixia and any subsidiaries, other than Excluded Employees
(as defined below), are Eligible Employees for purposes of the 2005 Bonus Plan. The following
employees of the Company and any U.S. subsidiaries are Excluded Employees for purposes of the 2005
Bonus Plan:

	 	1.  	Commissioned employees;
	 
	 	2.  	Employees who are expressly covered by any other Ixia 2005 bonus plan (e.g.,
employees of the Company’s Romanian and Indian subsidiaries); and
	 
	 	3.  	Casual, co-op or temporary employees

In order to earn and be eligible to receive a Quarterly Bonus, a person must be employed by Ixia or
one of its subsidiaries as an Eligible Employee (i) during the calendar quarter for which the bonus
is payable; and (ii) on the date on which such bonuses are paid, unless such requirement(s) is
waived in writing by the Chief Executive Officer of the Company (the “CEO”), in his sole
discretion. An employee’s eligibility under the 2005 Bonus Plan shall be determined on a
quarter-by-quarter basis. An employee who is on an approved leave of absence from the Company
during a calendar quarter will, for purposes of determining eligibility under the 2005 Bonus Plan,
may be treated as being employed by the Company during such leave of absence if so determined by
the CEO, in his sole discretion.

Quarterly Bonuses:

While the bonuses will be paid quarterly, they will be calculated on a year to date basis in order
to balance uneven results from quarter to quarter. The financial measure for calculating the

 

 

Quarterly Bonuses will be the Company’s year to date GAAP operating income calculated on a
consolidated basis (“Target”). The amount of bonus allocated as a Quarterly Bonus to the bonus
pool in which an Eligible Employee participates will be calculated by multiplying (i) the Eligible
Employee’s actual year to date earnings by (ii) the Bonus Percentage determined under the “Bonus
Participation Levels” formula described below (examples of Bonus Percentages are listed below in
Table 1) and by (iii) the applicable Cumulative Weighting Factor for such quarter as listed in
Table 2, less any Quarterly Bonuses paid for previous quarters during the year.

Stated mathematically, the amount of a Quarterly Bonus equals (AxBxC)-D, where A = an Eligible
Employee’s actual earnings paid year to date; B = the applicable Bonus Percentage (examples of
which are listed in Table 1 below) based on actual financial results; C = the Cumulative Weighting
Factor listed in Table 2 below; and D = Bonuses paid previously during the year.

All bonuses so calculated for each quarter will be pooled by functional department (e.g.,
Application Development, Customer Support, Finance, etc.), provided that executive officers (other
than the CEO who shall not be part of any pool) and non-executive Vice Presidents shall be in a
separate bonus pool (the “Officer Pool”). The Vice Presidents of each department will then
allocate these bonus pools to individual employees based on their assessment of an employee’s
performance for the quarter; provided, however, that Quarterly Bonuses for any Vice President who
is an executive officer of the Company may only be allocated in an amount that differs from the
amount determined in accordance with the mathematical calculation described in the preceding two
paragraphs (each, a “Formula Amount”) if such allocation is approved by the Compensation Committee
of the Company’s Board of Directors (the “Compensation Committee”). The bonuses for Vice
Presidents who are not executive officers will be allocated from the Officer Pool by the CEO.

Review of Bonus Amounts:

Before payment of the quarterly bonuses, Human Resources and Finance will review the bonus
allocations for all employees, except for those payable to the CEO and Vice Presidents, for
reasonableness. The CEO will then give final approval for all bonuses except for his own and
except for those payable to an executive officer of the Company in the event that the CEO
recommends to the Compensation Committee that the bonus for such executive officer be in an amount
other than a Formula Amount. The Compensation Committee will approve the CEO’s bonus payment on a
quarterly basis and, in the event that the CEO recommends bonus payments for executive officers
that differ from the applicable Formula Amounts, will also approve such bonus payments on a
quarterly basis.

Bonus Participation Levels:

For each calendar quarter, the bonus rate is determined by reference to the formula set forth in
this paragraph. The baseline bonus rate where 100% of Target is met is set forth in Table 1 below.
No bonus is payable below 75% of Target. The baseline bonus rates (for 100% of Target) and
illustrative bonus rates (for varying levels of Target achievement) are shown in the following
matrix. Between 90% to 120% of the Target, the bonus rate increases or decreases from the baseline
bonus rate by the ratio of actual GAAP operating income divided by Budgeted GAAP Operating Income.
The bonus rate is adjusted downward by a factor of 2x for performance below 90% of Target. Above
120% of the target, the bonus increases by a factor of 1.5x for that portion above 120%. For
results between the listed values or above 130% of Target, the Bonus Percentage should be
interpolated or extrapolated ratably.

2

 

By way of example only, if the Company were to achieve 82% of Target, the bonus rate for the CEO
would be:

	 	a.  	85% (i.e., the baseline bonus rate at 100% of Target) multiplied by 82% (i.e., ratio of
achieved operating income to Target) = 69.7%, less
	 
	 	b.  	85% multiplied by (90% — 82%) (i.e., to double the downward adjustment for performance
under 90%) = 6.8%
	 
	 	c.  	Bonus rate = 69.7% — 6.8% = 62.9%

For performance above Target on an annual basis, the Board shall have the discretion to increase
the yearend bonus payout for employees of the Company, and the Compensation Committee will have the
discretion to increase the year-end bonus payout for the CEO and other executive officers of the
Company.

Weighting Factor:

To recognize the fact that Operating Income is not earned evenly over the year, the Cumulative
Weighting Factor as determined in accordance with Table 2 will be applied when calculating bonuses
payable for a given quarter.

Discretionary Bonuses:

Discretionary bonuses may also be paid under the 2005 Bonus Plan but only if, in Management’s view,
the Company is able to pay a discretionary bonus without materially adversely affecting the
Company’s financial results and special circumstances exist. Consideration for such bonuses may be
given for special circumstances or achievements by a division, group or individual, or the Company.
The Chief Executive Officer of the Company has the authority to award discretionary bonuses to
Eligible Employees other than executive officers, and the Compensation Committee has the authority
to award discretionary bonuses to Eligible Employees who are executive officers, including the CEO.
