EXHIBIT 10.4 - ------------ JONES LANG LASALLE Telephone +1 312 228 2391 March 19, 2004 Mr. Stuart L. Scott 200 East Randolph Drive, 43rd Floor Chicago, Illinois 60601 Dear Stuart: The Compensation Committee (the "Committee") of the Board of Directors of Jones Lang LaSalle Incorporated (the "Company") has authorized me to confirm to you in writing your compensation as interim President and Chief Executive Officer (the "Interim CEO") of the Company during the period in which a search is conducted to fill that position on a permanent basis (the "Permanent CEO"). Your duties in such position will be those contemplated for the Chief Executive Officer in the Company's By-Laws, provided that the Committee does acknowledge that approximately ten percent of your normal work schedule may be devoted to business and/or not-for- profit activities in which you have become involved outside of the Company. Retroactive to January 1, 2004, the Company will compensate you semi- monthly at the annualized base salary of $400,000 (the "Interim Base Salary"). You will be paid your Interim Base Salary until the date on which the Permanent CEO actually commences employment with the Company, after which date your compensation will revert to the amount of base compensation (and with the termination date) set forth in the previous letter to you from Thomas C. Theobald, a copy of which is attached (the "Previous Letter"). Your employment duties at that time will also revert to those set forth (and with the termination date) set forth in the Previous Letter. You are also eligible to receive an annualized target bonus for service rendered as Interim CEO during 2004 in the amount of $600,000 (the "CEO Target Bonus"), which shall be pro-rated for the number of whole weeks from January 1, 2004 through the date on which the Permanent CEO actually commences employment with the Company (the "New CEO Hire Date"). The determination of the actual amount of the CEO Target Bonus to be paid to you shall be within the sole discretion of the Committee. Factors included in considering individual bonus awards include, without limitation, (1) your performance against specific IPMP objective and subjective standards that have been developed with the Committee, (2) your performance against the responsibilities set forth in the Previous Letter, (3) the overall performance of the Company and (4) the subjective evaluation by the Committee. A consideration of these factors may lead to your receiving more than, or less than, the targeted amount set forth above. From the New CEO Hire Date through December 31, 2004, you will be eligible to receive an annualized target bonus, which shall be pro-rated for the number of whole weeks occurring during such period, of $80,000 as set forth in the Previous Letter and based upon the Committee's determination in its sole discretion of your performance of the roles outlined therein. As contemplated by the Previous Letter, you and the Committee have agreed that you will retire from all positions with the Company (except as Chairman of the Florida Office Fund and potentially with respect to certain other positions held with LaSalle Investment Management entities to be mutually agreed upon) and from your service on the Company's Board of Directors on December 31, 2004. To earn and be paid the bonuses contemplated above, you must not voluntarily terminate your employment prior to that date. Your bonuses will be determined and paid during 2005 at the same time as the Company generally makes its bonus determinations and payments for its employees. While you remain employed at the Company, you will continue to be eligible to receive benefits under the Company's policies and plans as in effect from time to time.
