         To simplify the transactions contemplated by the Merger Agreement, the

result of these assignments, Benchmark will, prior to and at the Effective Time

partnership interests in each of Fund IX, Fund X and Fund XI.

         The parties agree that the definition of Assignment of New Fund

this Agreement should be found invalid, illegal or unenforceable in any
respect, the validity, legality, and enforceability of the remaining provisions
contained herein shall not in any way be affected or impaired thereby. Any
