                           CALCULATION OF FILING FEE


                                       
      Transaction Valuation* $52,021,113  Amount Of Filing Fee $10,405


   *Estimated for purposes of calculating the amount of the filing fee only.
   This amount assumes the purchase of 4,523,575 shares of common stock, par
   value $.01 per share (the "Shares"), of Robertson-Ceco Corporation, a
   Delaware Corporation (the "Company"), at the tender price of $11.50 per
   share net to the seller in cash, without interest thereon. Pursuant to the
   Agreement and Plan of Merger, dated as of April 20, 2000, between RHH
   Acquisition Corp. ("Purchaser") and the Company, the Company represented
   that as of such date, it had 16,096,550 shares outstanding. Purchaser
   already beneficially owns 11,572,975 shares which will not be tendered.
   Based on the foregoing, the transaction value is equal to the product of
   (i) (A) 16,096,550 shares (the number of shares outstanding), minus (b)
   11,572,975 (the number of shares beneficially owned by Purchaser),
   multiplied by (ii) $11.50. The amount of the filing fee, calculated in
   accordance with Rule 0-11 Under the Securities Exchange Act of 1934, as
   amended, equals 1/50 of one percent of the aggregate of the cash offered by
   the Purchaser.
