Section 5.4 Permitted Investments. The Company and BNU shall discuss and agree on the type of investments in which the Company may, from time to time, invest any and all of the Cash Deposit (including any accrued interest thereon), provided that (a) the investment rights are assigned to BNU by way of pledge or endorsement and subject to the terms of this Agreement, (b) BNU shall not unreasonably withhold its approval on any investments proposed by the Company and (c) such investments shall be limited to those that are Permitted Investments.
