The Reporting Persons acquired the Shares based on the Reporting Persons’ belief that such Shares, when acquired, were undervalued and represented an attractive investment opportunity.

CUSIP No. 760273102

The Reporting Persons remain passive investors in the Issuer and are filing the Schedule 13D solely as a result of beneficially owning in excess of 20% of the outstanding Shares (see Explanatory Note above). The Reporting Persons have not acquired the Shares with a purpose or effect of changing or influencing control of the Issuer and no Reporting Person has any present plan or proposal which would relate to or result in any of the matters set forth in subparagraphs (a) - (j) of Item 4 of Schedule 13D.
