assertion in the Letter to MRC Stockholders: "MRC is likely to
                                                        generate hundreds of
millions of dollars in the next few years..." Statements regarding
                                                        future value may
violate Rule 14a-9, absent sufficient support and specificity. See the
                                                        Note to Rule 14a-9.
Revise to express as an opinion, to specify what is meant by "the next
                                                        few years," and to
explain the basis for your belief and whether you are referring to
                                                        profits, revenues, etc.
Alternatively, please delete.

more specific.
