                        TRANSPORTATION SERVICES AGREEMENT

         THIS TRANSPORTATION SERVICES AGREEMENT (this "Agreement") is entered
into as of December 18, 2003, by and between KANDERS AVIATION, LLC, a Delaware
limited liability company with offices at One Pickwick Plaza, Greenwich,

                                   WITNESSETH:

         WHEREAS, Kanders Aviation owns a fractional interest in, operates and
maintains certain aircraft (collectively, the "Aircraft"), to provide
transportation services for the use of, among others, Kanders Aviation and
certain of its direct or indirect affiliates; and

         WHEREAS, Clarus may, from time to time, desire to utilize such
transportation services from Kanders Aviation, and Kanders Aviation may, in its
discretion, elect to provide such services to Clarus, upon the terms and
conditions set forth herein.

         NOW, THEREFORE, in consideration of the premises and the mutual
covenants, representations and warranties contained herein, and for other good
and valuable consideration, the receipt and sufficiency of which is hereby
acknowledged, the parties hereto agree as follows:

         1. Services. Upon Clarus' request, Kanders Aviation may, in its sole

                    service provided as reasonably determined by Kanders
                    Aviation, but which will in no event exceed the NetJets'
                    published rates for such services, to the extent such
                    published rates are available, and

            (b)     any additional expenses incurred by Kanders Aviation in
