                                   ARTICLE 2

                                MCP-1 AGREEMENT

            research and/or development of MCP-1 inhibitors with Kyowa Hakko
            Kogyo Co., Ltd., a Japan corporation ("Kyowa"), and its Affiliates."

            (b)  SECTION 4.1. The fifth, sixth and seventh sentences of SECTION
            4.1 of the MCP-1 Agreement (beginning "Forty-five (45) days after

            following: "If Warner exercises marketing rights for a Development
            Candidate within the stated period, the Development Candidate shall
            become a "Warner Product". The parties acknowledge that although
            many references to "Warner-LeukoSite Products" remain in the MCP-1
            Agreement, the effect of this SECTION 2.1(b) is to remove the
            possibility of a Development Candidate from becoming a
            "Warner-LeukoSite Product" and, therefore, unless LeukoSite's
            co-promotion rights are reinstated pursuant to SECTION 2.2 of this
            Global Amendment such references have no effect.

            (c)  SECTION 5.3(a). SECTION 5.3(a) of the MCP-1 Agreement is hereby
            amended by deleting the phrase "and/or" before the number "(iv)",

            development, marketing, sale and/or manufacture of compounds with
            Kyowa and/or its Affiliates".

            (d)  SECTION 5.5(c). SECTION 5.5(c) of the MCP-1 Agreement is hereby
            amended by adding the following immediately before the end of such
            Section: ", and may also take into consideration Warner's
            relationships with third parties (such as Kyowa)".

            (e)  SECTION 5.6(a). SECTION 5.6(a) of the MCP-1 Agreement is hereby
            deleted in its entirety and replaced by the following: "For each
            Warner Product, Warner will pay LeukoSite ***of worldwide, annual
            Net Sales up to **********, *** of worldwide, annual Net Sales
            above *********** and up to *********, and *** of worldwide,
            annual Net Sales above ***********."

      2.2   REINSTATEMENT OF CO-PROMOTION RIGHTS. Warner may at any time, in
its sole discretion, terminate SECTIONS 2.1(b) and 2.1(e) of this Global

notice to Warner. Thereafter, the parties will proceed as follows:   

                                      2
   3
            (a)  REMAIN A WARNER PRODUCT. If LeukoSite does not elect to convert
            such Warner Product to a Warner-LeukoSite Product, LeukoSite and
            Warner will estimate in good faith the designated share of
            Development Costs that LeukoSite would have paid under SECTION 4.2
            of the MCP-1 Agreement for the periods set forth in SUBSECTION
            5.6(a)(i), (ii), or (iii) of the MCP-1 Agreement. Before the end of
            the 45 day period, LeukoSite will pay Warner the Development Costs
            referred to in SUBSECTION 5.6(a)(i), (ii), or (iii), and thereafter
            LeukoSite will be entitled to receive the royalty rates referred to
            in such Subsection. If Warner terminates SECTION 2.1(b) and 2.1(e)
            of this Global Amendment prior to completion of all Phase II
            clinical studies reasonably deemed necessary by the Management
            Committee for regulatory approval to market the Product in the
            United States of America, LeukoSite may elect to pay the designated
            share of Development Costs that LeukoSite would have paid under
            SECTION 4.2 of the MCP-1 Agreement up to and including the time that
            Warner terminates such SECTION 2.1(b) and 2.1(e), and thereafter
            LeukoSite may continue to pay its designated share of Development
            Costs as they become due in order to preserve its rights to a
            greater royalty under SECTION 5.6(a) of the MCP-1 Agreement.

            (b)  CONVERT TO A WARNER-LEUKOSITE PRODUCT. If LeukoSite does elect
            to convert such Warner Product to a Warner-LeukoSite Product,
            LeukoSite and Warner will estimate in good faith the designated
            share of Development Costs that LeukoSite would have paid under
            SECTION 4.2 of the MCP-1 Agreement up to and including the earlier
            of (i) the time of such election and (ii) NDA approval in the United
            States. Thereafter, if such election occurs prior to such NDA
            approval, LeukoSite will continue to pay its designated share of
            Development Costs as they become due up to and including such NDA
            approval in order to keep such Warner-LeukoSite Product from
            reverting to a Warner Product.
