Dear David:

This letter will serve as a first amendment to and restatement of your May 28,

We are pleased to confirm your continued employment with Heidrick & Struggles,
Inc. and want to set forth our understanding as follows:

     continue to be employed with our Company (based in Dallas, Texas) as
     President and Chief Executive Officer, Heidrick & Struggles Executive
     Search Division, and be responsible for the general management of the
     affairs of the Executive Search Division. You will report to the Chairman
     and President - Chief Executive Officer of Heidrick & Struggles
     International, Inc.

     Effective January 1, 2001, your monthly base salary shall be $50,000.00
     (which is $600,000.00 annually). Thereafter, your base salary will be
     reviewed on at least an annual basis for possible merit increases.

2.   Effective for the calendar years 2001 and 2002 you will have the
     opportunity to receive a performance-based incentive bonus which will be
     determined by the Compensation Committee of the Board of Directors

     The bonus component of your compensation will be paid on normal bonus
     payment dates which are currently in December and the following March.
     Your total compensation may include participation in our GlobalShare
     Program, so that your bonus may be partially paid in equity in accordance

          Company or its affiliates by you, the conviction of, or the entrance
          of a plea of guilty or nolo contendere by, you to a felony which has
          the potential to have a negative impact upon the Company's reputation
          or otherwise bring the Company, any of its affiliates, or the CEO into
          disrepute, or the termination of your employment with the Company
          pursuant to the Company's Harassment Policy; or gross neglect or
          willful misconduct by you in carrying out your duties under this

     to you arising from such termination and you shall not be entitled to
     receive any other payment arising from or respecting your employment or its
     termination except for payments to you of any benefits under the written
     terms and conditions of written benefit plan documents.

7.   If the Company terminates your employment other than for "Cause," as
     defined in this Agreement, or in the event there is a Constructive
     Termination Without Cause as defined in this Agreement, at any time on or
     before December 31, 2002, we shall pay you your (a) base salary through the
     date of termination to the extent not theretofore paid; (b) a lump sum
     amount equal to the product of one (1) times your base salary in effect on

     prior three years, payable promptly following the date of termination. In
     addition, all outstanding options or equity instruments shall immediately
     become exercisable and shall remain exercisable for the remainder of their
     originally scheduled terms.

     "Constructive Termination Without Cause" shall mean termination of your
     employment at your initiative within 30 days following the occurrence of
     any of the following events without your consent:

     (i)    a reduction in your then current base salary or target bonus
            opportunity;

     (ii)   a reduction in the aggregate value of the benefits provided to you
            under the Company's medical, health, accident, disability, life
            insurance, thrift and retirement plans, other than any reduction
            that occurs as a result of a modification or termination of such
            plans and programs which affects all participants in such plans or
            programs;

     (iii)  your removal from the position described in Section 1 above;

     (iv)   a material diminution in your duties as described in Section 1
            above; or

            its obligation to perform this Agreement by any successor to all or
            substantially all of the assets of the Company within 15 days after
            a merger, consolidation, sale or similar transaction.

     Following written notice from you of any of the events described above, the
     Company shall have 30 calendar days in which to cure.  If the Company fails
     to cure, your termination shall become effective on the 31st calendar day
     following the written notice.

8.   If you voluntarily terminate your employment, we will pay you your base
     salary through the date of the termination; and all outstanding options
     which are not then exercisable shall be forfeited; exercisable options
     shall remain exercisable until the earlier of the 30th day after the
     date of termination or the originally scheduled expiration date of the
     options unless the Compensation Committee determines otherwise.

9.   In the event that your employment is terminated due to your death or
     disability, you or your estate or your beneficiaries, as the case may be,
     shall be entitled to: (a) receive your base salary through the date of
     termination, to the extent not theretofore paid; (b) a "Pro Rata" annual
     incentive award for the calendar year in which your death or disability
     occurs, based on the higher of (1) the cash bonus for the prior year or (2)
     the average of the cash bonuses for the prior three years, payable in a
     single installment promptly after your death; and all outstanding options
     or equity instruments, whether or not then exercisable, shall become
     exercisable and shall remain exercisable for the remainder of their
     originally scheduled terms.

     For purposes of this section "Pro Rata" shall mean a fraction, the
     numerator of which is the number of days that you were employed in the
     calendar year and the denominator of which shall be the number of days in
     the calendar year.

10.  At the expiration of this Agreement, at your option and with the consent of
     the Board, you may have a paid leave of absence of up to six months (the
     "LOA Period"). The Board's consent may not be unreasonably withheld and
     should be given provided that the Company and its affiliates are doing
     well, and there is no pressing business reason to postpone or shorten the
     LOA Period. During the LOA Period you will receive your then current
     monthly base salary for each month during the LOA Period. During the LOA
     Period, it is our expectation and desire that you will continue to maintain
     business development-related activities to retain your business contacts
     and relationships. You will be reimbursed for your reasonable business
     development expenses upon receipt of the customary expense report.

11.  You acknowledge that the Confidentiality Letter Agreement dated June 3,
     1992 (the "Confidentiality Agreement") between you and the Company remains
     in full force and effect. Any breach of the Confidentiality Agreement shall
     constitute a material breach of this Agreement.

12.  In consideration of your continued employment and the new employment terms
     set forth in this Agreement, you agree that you will not, at any time
     during the term of your employment under this Agreement and for a period of
     twelve months after any termination of your employment with the Company for
     any reason (other than death or disability), directly or indirectly, acting
     with others or alone, manage, operate or control, engage or become
     interested in as an owner (other than as an owner of less than 5% of the
     stock of a publicly owned company), stockholder, partner, director,
     officer, employee (in an executive capacity), consultant or otherwise in
     any business that is a "Competitive Business" with the Company in any
     geographic location in which the Company conducts its business. For
     purposes of this Section, a business operation shall be considered a
     "Competitive Business" with the Company or its affiliates if such business
     operation provides services in the executive search business. You
     acknowledge that the amounts payable to you by the Company in the event of
     your termination of employment by the Company without Cause is intended to
     provide additional consideration for this noncompetition Agreement.

Ms. Stephanie W. Abramson

New York, NY 10023

Dear Stephanie:

On behalf of Heidrick & Struggles, Inc., I am pleased to confirm our offer of
employment to you as Chief Legal and Corporate Development Officer and Corporate
Secretary reporting to the Chief Executive Officer of Heidrick & Struggles
International, Inc (the "Company"). You will also have the internal title of
Senior Partner. You will serve as Secretary of the Board of Directors of the
Company, and as such, will be expected to attend all Board meetings. You will
also be a member of the "Office of the CEO" and will be asked to participate in
our Heidrick Ventures division. Initially and until otherwise specified within
mid-town Manhattan, you will be located in our 245 Park Avenue, New York office.
Attached to this letter, for reference purposes, is a copy of my November 30,
2000, memorandum to you which outlines my view of your initial responsibilities.

I look forward to seeing you on February 12, 2001, your first day of employment.
Your monthly base salary is $45,833.34, which equals $550,000.00 annually.
Currently, salaries are reviewed annually in November/December, so you can
expect your first salary review in November/December 2001.

Your annual bonus target for 2001 is 100% of base salary of which $300,000 is
guaranteed to be paid when bonuses are paid in December of 2001 and March of
2002.  Following 2001, you will participate in the regular bonus program then in
effect for employees at your level.  Bonuses are discretionary and are not
earned until approved by the Compensation Committee and/or the Board of
Directors of the Company and, subject to the paragraph below relating to
termination without Cause including resignation for Good Reason and Change in
Control, will be payable only if you are in the Company's employ on the regular
bonus payment dates.   Your total cash compensation will be subject to the
Heidrick & Struggles GlobalShare Program.  As such, any bonus you receive may be
partially paid in equity in accordance with the GlobalShare Program.

You will receive a stock option grant to purchase 25,000 shares of Heidrick &
Struggles International, Inc. common stock.  The options will be granted to you
within 30 days of your employment start date. The options will be issued at Fair
Market Value on the date of grant, will vest in increments of 25% on the first,
second, third and fourth anniversaries of the date of grant, and will have a
five-year term, except to the extent that vesting will be accelerated pursuant
to the terms of the plan under which they are granted or in connection with a
Change in Control.

In addition, within 30 days following your employment start date, the Company
will loan you $925,000.00 to be evidenced by a non-interest bearing Promissory
Note ("Note") payable on December 31, 2004, except that, unless your employment
is terminated by the Company without Cause or you have resigned for Good Reason,
if you cease to be in the Company's employ, then the entire principal balance of
the Note then remaining due shall, without demand or notice of any kind, be and
become immediately due and payable within 30 days.

The Note will be forgiven if you are in the Company's employ (unless the Company
has terminated your employment without Cause or you have resigned for Good
Reason) on the following forgiveness dates:  $462,500.00 on December 31, 2002;
$231,250.00 on December 31, 2003; and $231,250.00 on December 31, 2004.  The
income arising from the loan principal forgiveness will be subject to personal
income tax withholding attributable to the forgiveness income when due.  The
Company is authorized to deduct the amounts required to be withheld from your
cash bonus(es), or, if the bonus amount is less than the withholding, you will,
immediately within 10 days, reimburse the Company for withholding payments made
to the extent not covered by your bonus.  The Company will reimburse you on a
grossed-up basis for any income tax arising out of the interest-free nature of
the loan.

In the event the Company terminates your employment without Cause or you resign
for Good Reason prior to March 31, 2002, you shall be entitled to receive as
severance pay, in a lump sum as soon as administratively feasible after the date
of termination or resignation for Good Reason, an amount equal to twelve months
of base salary plus the full amount of your target bonus for the year in which
the termination occurs.  Thereafter, except in connection with a Change in
Control as set forth below, in the event the Company terminates your employment
without Cause, you shall be entitled to receive as severance pay an amount
consistent with the Company's then existing policy for corporate management.

In the event the Company terminates your employment without Cause or you resign
for Good Reason within one year following a Change in Control, you shall be
entitled to receive as severance pay, in a lump sum as soon as administratively
feasible after the date of termination or resignation for Good Reason, an amount
equal to (i) twelve months of base salary plus twelve months of target bonus and
(ii) the prorated portion of your target bonus for the year in which the
termination occurs based on the number of months worked in such year.  You shall
also be entitled to either continuing participation in disability coverage or
the reimbursement on a gross-up basis for the premium costs for disability
coverage, until the first anniversary of termination of employment or
resignation for Good Reason or such time as you are covered by comparable
programs of a subsequent employer.  The Company shall also reimburse you for
costs attributable to your participation in COBRA.  In addition, all outstanding
options or other equity instruments may become immediately exercisable in
accordance with the terms of the 1998 Heidrick & Struggles GlobalShare Program
I, as amended from time-to-time, and the terms of any successor equity programs.
In the event that a Change of Control payment to you is required, the Company
agrees to reimburse you for the excise tax, if any, incurred by you under
Internal Revenue Code (S) 280G.

          for stock options or other incentive programs unless such diminution
          is consistent with other employees at your level; (ii) the elimination
          of your position or a diminution of responsibilities associated with

     compensation at any time with or without Cause or notice, except for such
     period of notice as may be expressly provided in writing under written

     any way, prohibit your joining our firm or performing your work with us.
