This Article V constitutes a present assignment effective as of the Effective Date, but in the event that the Mortgagee should elect not to exercise immediately its right to receive Hydrocarbons or Proceeds, then the purchasers or other persons obligated to make such payment may continue to make payment to Mortgagor until such time as written demand has been made upon them by the Mortgagee that payment be made directly to the Mortgagee. Such failure to notify shall not in any way waive the right of the Mortgagee to receive any payments not theretofore paid out to the Mortgagor before the giving of written notice. In the event payments are made directly to the Mortgagee, and then, at the request of the Mortgagee, payments are for a period or periods of time paid to the Mortgagor, the Mortgagee shall nevertheless have the continuing right, effective upon written notice, to require that future payments be again made to the Mortgagee. The Mortgagor and the Mortgagee agree, and it is the intention of the Mortgagor and the Mortgagee, that in no event will any reduction in the Loan Obligations or the other Secured Indebtedness be measured by the fair market value of the Hydrocarbons, other minerals, proceeds, or other rents, profits, or income assigned to the Mortgagee under this instrument.
