Jeffrey T. Carr

RE: TERMS OF EMPLOYMENT

Dear Jeffrey,

     This letter will confirm the terms of your offer of employment with Taleo
Corp., a Delaware corporation ("Taleo"). Such terms are as follows:

          1. POSITION AND RESPONSIBILITIES. You will serve in the position of
Executive Vice President of Marketing and Chief Strategy Officer reporting
directly to the Chief Executive Officer. You will assume and discharge such
responsibilities as are commensurate with such position and as the Chief
Executive Officer may direct from time to time. During your employment with
Taleo, you shall devote your full time, skill and attention to your duties and
responsibilities and shall perform faithfully, diligently and competently. In
addition, you shall comply with and be bound by the operating policies,
procedures and practices of Taleo in effect from time to time during your
employment.

     While Taleo cannot commit to this promotion taking place, it is well
understood that your objective is to become COO of Taleo within six to twelve
(6-12) months of your employment start date. No later than June 30, 2005, a
formal review process will take place with the CEO with a goal to assess and
transition towards this goal. In the event you are promoted to COO, your
compensation will be adjusted to reflect a Base Salary, as defined below, of
$250,000 and Incentive Compensation, as defined below, of $250,000 at 100%
achievement of goal. Concurrently, Taleo will enter into a good faith discussion
and evaluation with you regarding an appropriate increase in your equity stake
in Taleo.

          2. AT-WILL EMPLOYMENT. You acknowledge that your employment with Taleo
is for an unspecified duration and constitutes at-will employment and that
either you or Taleo can terminate this relationship at any time, with or without
Cause and with or without notice.

          3. COMPENSATION.

               (a) In consideration of your services, you will be paid a salary
of $18,750 US per month (annualized base salary of $225,000.00 US) payable in
two monthly payments in accordance with Taleo's standard payroll practices
("Base Salary").

               (b) In addition to your base salary, you will be eligible for
incentive bonuses for each fiscal quarter or fiscal year of Taleo ("Incentive
Compensation"). The bonuses will be awarded based on criteria established by
Taleo's Chief Executive Officer and approved by Taleo's Board of Directors. The
aggregate amount of your target bonuses at 100% achievement of goal for a fiscal
year will be equal to 100% of your annual base salary. The bonus for a fiscal
quarter or fiscal year will be paid in accordance with Taleo's standard
practices for payment of bonuses. For fiscal year 2005, you will be eligible to
participate in the Incentive Compensation Plan attached hereto as Attachment A,
which will be deemed to meet the requirements of this Subsection (b) for 2005.
For the fourth quarter of fiscal year 2004 (i.e., October - December of 2004),
you shall be paid a bonus equal to the quarterly bonus specified in Attachment A
at 100% achievement of goal (i.e., $45,000), prorated for the number of days you
were employed by Taleo in the fourth quarter of fiscal year 2004.

               (c) If, prior to being promoted to the position of Chief
Operating Officer, Taleo terminates your employment for any reason other than
Cause or if you resign for Good Reason, then Taleo will continue to pay your
Base Salary at the rate in effect at the time of your resignation or termination
of your employment for a period of six (6) months from the date of your
resignation or termination of your employment and you shall continue to vest in
stock options in accordance with the schedule specified in Attachment C for a
period of six (6) months from the date of your resignation or termination of
your employment ("Vesting Period 1"). Such vested options shall expire ninety
(90) days after the expiration of Vesting Period 1. If, after you have been
promoted to the position of Chief Operating Officer, Taleo terminates your
employment for any reason other than Cause or if you resign for Good Reason,
then Taleo will continue to pay your Base Salary at the rate in effect at the
time of your resignation or termination of your employment for a period of six
(6) months from the date of your resignation or termination of your employment,
Taleo will pay your aggregate target bonuses under Subsection (b) above at 100%
achievement of goal for a period of six (6) months from the date of your
resignation or termination of your employment and you shall continue to vest in
stock options in accordance with the schedule specified in Attachment C for a
period of twelve (12) months from the date of your resignation or termination of
your employment ("Vesting Period 2"). Such vested options shall expire ninety
(90) days after the expiration of Vesting Period 2. If, within one (1) year
following a Change in Control (as defined in Attachment C), Taleo or the
successor corporation terminates your employment for any reason other than Cause
or if you resign for Good Reason, regardless of whether you have been promoted
to the position of Chief Operating Officer, then Taleo or the successor
corporation will continue to pay your Base Salary at the rate in effect at the
time of your resignation or termination of your employment for a period of
twelve (12) months from the date of your resignation or termination of your
employment and will pay your aggregate target bonuses under Subsection (b) above
at 100%

achievement of goal for a period of twelve (12) months from the date of
termination of your employment. Your severance benefit will be paid in
accordance with Taleo's standard payroll procedures.

               (d) If Taleo terminates your employment for any reason other than
Cause or if you resign for Good Reason, then Taleo will pay you your incentive
bonus under Subsection (b) above for the fiscal year and/or quarter in which
your resignation or the termination of your employment occurs, prorated to
reflect the actual number of days of your employment in that fiscal year and/or
quarter.

               (e) If Taleo terminates your employment for any reason other than
Cause or if you resign for Good Reason, and if you elect to continue your health
insurance coverage under the Consolidated Omnibus Budget Reconciliation Act
("COBRA") following the termination of your employment, then Taleo will pay the
same portion of your monthly premium under COBRA as it pays for active employees
until the earliest of (i) the close of the 12-month period following the
termination of your employment, (ii) the expiration of your continuation
coverage under COBRA or (iii) the date when you become eligible for
substantially equivalent health insurance coverage in connection with new
employment or self-employment.

               (f) If your employment is terminated by Taleo with Cause, or if
you resign your employment voluntarily without Good Reason, no compensation or
other payments will be paid or provided to you that would have, or might have,
become payable to you in periods following the date when such a termination of
employment is effective. Any rights you may have under any Taleo plan regarding
Benefits, as defined below, shall be determined under the provisions of those
plans. If your employment terminates as a result of your death or disability, no
compensation or payments will be made to you other than those to which you may
otherwise be entitled under any Taleo plan regarding Benefits.

               (g) For purposes of this Section 3, "Cause" means (i) any act of
personal dishonesty taken by you in connection with your responsibilities under
this agreement that is intended to result in your personal enrichment, (ii) your
conviction of a felony, (iii) any act by you that constitutes material
misconduct and is injurious to Taleo or (iv) substantial violations of
employment duties, responsibilities or obligations to Taleo that are
demonstrably willful and deliberate.

               (h) For purposes of this Section 3, "Good Reason" means (i)
without your consent, a significant reduction of your duties, position or
responsibilities relative to your duties, position or responsibilities in effect
immediately prior to such reduction other than a reduction where you are asked
to assume substantially similar duties and responsibilities as the head of a
division of a larger entity or as a Section 16 officer of the parent company of
which Taleo becomes a part due to a Change in Control, (ii) without your
consent, a substantial reduction of the facilities and perquisites (including
office space and location) available to you immediately prior to such reduction,
(iii) without your consent, a reduction by Taleo of your base salary as in
effect immediately prior to such reduction, (iv) without your consent, a
material reduction by Taleo in the kind or level of employee benefits to which
you are entitled
<PAGE>
Mr. Jeffrey T.Carr
November 17, 2004
Page 4


immediately prior to such reduction, with the result that your
overall benefits package is significantly reduced, (v) without your consent,
your relocation to a facility or a location outside the San Francisco Bay Area
or (vi) any purported termination of you other than for Cause.

          4. OTHER BENEFITS. You will be eligible to receive the standard
employee benefits made available by Taleo to its employees from time to time
during the term of your employment to the extent of your eligibility therefore
("Benefits"). You shall earn paid vacation at the rate of three weeks per year
of employment (which shall be consistent with Taleo's vacation policy and which
shall not accrue in excess of that allowable under the policy). In the event you
are promoted to Chief Operating Officer, you shall earn paid vacation at the
rate of four weeks per year of employment (which shall be consistent with
Taleo's vacation policy and which shall not accrue in excess of that allowable
under the policy). During your employment, you shall be permitted, to the extent
eligible, to participate in any group medical, dental, life insurance and
disability insurance plans, or similar benefit plan of Taleo that is available
to employees generally. You should note that Taleo may modify salary and
benefits from time to time as deemed necessary. Base Salary and Incentive
Compensation are not considered Benefits as that term is used in this agreement.

     Taleo shall reimburse you for all reasonable business expenses actually
incurred or paid by you in the performance of your services on behalf of Taleo,
upon prior authorization and approval and upon submission of appropriate
documentation in accordance with Taleo's expense reimbursement policy.

          5. PARACHUTE EXCISE TAX GROSS-UP.

               (a) GROSS-UP PAYMENT. If it is determined that any payment or
distribution of any type to you or for your benefit by Taleo, any of its
affiliates, any person who acquires ownership or effective control of Taleo or
ownership of a substantial portion of Taleo's assets (within the meaning of
section 280G of the Internal Revenue Code of 1986, as amended (the "Code"), and
the regulations thereunder) or any affiliate of such person, whether paid or
payable or distributed or distributable pursuant to the terms of this offer
letter or otherwise (the "Total Payments"), would be subject to the excise tax
imposed by section 4999 of the Code or any interest or penalties with respect to
such excise tax (such excise tax and any such interest or penalties are
collectively referred to as the "Excise Tax"), then you will be entitled to
receive an additional payment (a "Gross-Up Payment") in an amount calculated to
ensure that after you pay all taxes (and any interest or penalties imposed with
respect to such taxes), including any Excise Tax, imposed upon the Gross-Up
Payment, you retain an amount of the Gross-Up Payment equal to the Excise Tax
imposed upon the Total Payments, subject to Section 5(e) below.

               (b) DETERMINATION BY ACCOUNTANT. All determinations and
calculations required to be made under this Section 5 will be made by an
independent accounting firm selected by you from among the largest four
accounting firms in the United States (the "Accounting Firm"). The Accounting
Firm will provide its determination (the "Determination"), together with
detailed supporting calculations regarding the amount of any Gross-Up Payment
and any other relevant matter, to you and Taleo not less than forty-five (45)
days before the date
<PAGE>
Mr. Jeffrey T.Carr
November 17, 2004
Page 5


any such Excise Tax is due (if you reasonably believe that any of the Total
Payments may be subject to the Excise Tax). If the Accounting Firm determines
that no Excise Tax is payable by you, it will furnish you with a written
statement that it has concluded that no Excise Tax is payable (including the
reasons therefor) and that you have substantial authority not to report any
Excise Tax on your federal income tax return. If a Gross-Up Payment is
determined to be payable, it will be paid to you not less than thirty (30) days
before any such Excise Tax is due. Any determination by the Accounting Firm will
be binding upon Taleo and you, absent manifest error.

               (c) OVER- AND UNDERPAYMENTS. As a result of 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 not made
by Taleo should have been made ("Underpayment") or that Gross-Up Payments will
have been made by Taleo that should not have been made ("Overpayment"). In
either event, the Accounting Firm will determine the amount of the Underpayment
or Overpayment that has occurred. In the case of an Underpayment, the amount of
such Underpayment will promptly be paid by Taleo to you or for your benefit. In
the case of an Overpayment, you will, at the direction and expense of Taleo,
take such steps as are reasonably necessary (including the filing of returns and
claims for refund), follow reasonable instructions from, and procedures
established by, Taleo, and otherwise reasonably cooperate with Taleo to correct
such Overpayment, provided, however, that (i) you will in no event be obligated
to return to Taleo an amount greater than the net after-tax portion of the
Overpayment that you have retained or have recovered as a refund from the
applicable taxing authorities and (ii) this provision will be interpreted in a
manner consistent with the intent of Subsection (a) above, which is to make you
whole, on an after-tax basis, from the application of the Excise Tax, subject to
Section 5(e) below, it being understood that the correction of an Overpayment
may result in your repaying to Taleo an amount that is less than the
Overpayment.

               (d) STOCKHOLDER APPROVAL. If no stock of Taleo is readily
tradable and the stockholder approval exemption described in section
280G(b)(5)(A)(ii) of the Code may be available for one or more payments or
distributions to you or for your benefit, then you and Taleo will use their best
efforts to seek such approval in accordance with the regulations under section
280G of the Code and to cause such exemption to apply.

               (e) GROSS-UP PAYMENT CAP. Notwithstanding the foregoing or
anything in this Section 5, the total amount paid to you by Taleo as Gross-Up
Payments will not exceed $200,000.

          6. CONFLICTING EMPLOYMENT. During the term of your employment with
Taleo, you will not engage in any other employment, occupation, consulting, or
other business activity directly related to the business in which Taleo is now
involved or becomes involved during the term of your employment, nor will you
engage in any other activities that conflict with your obligations to Taleo.
This provision does not preclude you from serving on the boards of directors
and/or advisory boards of companies that are not competitors of Taleo.
