In accordance with Revenue Ruling 95-74, 1995-2, C.B. 36, payments made by Cendant, Realogy or Wyndham for or in respect of liabilities Assumed pursuant to this Agreement that, but for such Assumption by Cendant, Realogy or Wyndham, as the case may be, would have been deductible under Section 162 of the Code (and applicable provisions of state and local Law) or capitalized under Section 263 of the Code (and applicable provisions of state and local Law) or otherwise, as the case may be, by the original obligor pursuant to applicable principles of Tax Law, shall be treated for Tax purposes as payments actually made by Cendant, Realogy or Wyndham, as applicable, to Taxing Authorities that are deductible to Cendant, Realogy or Wyndham, as applicable, under Section 162(a) of the Code (and applicable provisions of state and local Law) or capitalized under Section 263 of the Code or otherwise, as the case may be; and
