                           upon anything contained in a Floating Rate Note, the
                           Description of Debt Securities, the Description of
                           the Medium-Term Notes or one or more Prospectus
                           Supplements.

                           10. (A) The Issuer agrees to notify the Calculation
                  Agent at least five London Business Days prior to the issuance
                  of any LIBOR Note. The Calculation Agent agrees to select four
                  Reference Banks prior to the issuance of the first LIBOR Note
                  by the Issuer; to make all appropriate arrangements for such
                  banks to act as Reference Banks; and to notify the Issuer, the
                  Trustee and each of the Agents as to the names and addresses
                  of such Reference Banks. The Calculation Agent covenants that,
                  for so long as it is required so to do in accordance with the
                  applicable Description of the Medium-Term Notes, it shall
                  ensure that there shall at all times be four Reference Banks.
                  Forthwith upon any change in the identity of the Reference
                  Banks, the Calculation Agent shall notify the Issuer, the
                  Trustee and the Agents of such change. If fewer than two
                  Reference Banks are quoting, the Calculation Agent agrees to
                  select three major banks in The City of New York in accordance
                  with the applicable Description of the Medium-Term Notes. The
                  Calculation Agent shall not be responsible to the Issuer or
                  any third party for any failure of the Reference Banks to
                  fulfill their duties or meet their obligations as Reference
                  Banks or as a result of the Calculation Agent having acted
                  (except in the event of negligence, wilful default or bad
                  faith) on any certificate given by any Reference Bank which
                  subsequently may be found to be incorrect.

                           (B) If necessary, in accordance with the provisions
                  set forth in the Prospectus Supplement relating to the Notes
                  dated December 5, 2001, under the Heading "Description of the
                  Medium-Term Notes--Floating Rate Notes--Prime Rate", the
                  Calculation Agent agrees to select a substitute major bank or
                  trust company (meeting the requirements specified under such
                  heading). The Calculation Agent shall not be responsible to
                  the Issuer or any third party for the failure of such bank or
                  trust company to fulfill any duty or obligation contemplated
                  under such heading.

                           (C) Except as provided below, the Calculation Agent
                  may at any time resign as Calculation Agent by giving written
                  notice to the Issuer and the Trustee of such intention on its
                  part, specifying the date on which its desired resignation
                  shall become effective, provided that such notice shall be
                  given not less than two months prior to the said effective
                  date unless the Issuer and the Trustee otherwise agree in

                           appointment to the holders of the Notes, provided
                           that if the Calculation Agent fails duly to establish
                           the amount of interest for any interest period, such
                           removal will take effect immediately upon such
                           appointment of, and acceptance thereof by, a
                           successor Calculation Agent approved by the Trustee
                           and qualified as aforesaid, in which event notice of
                           such appointment shall be given to the holders of the
                           Notes as soon as practicable thereafter. Upon its
                           resignation or removal becoming effective, the
                           retiring Calculation Agent shall be entitled to the

                           (D) If at any time the Calculation Agent shall resign
                  or be removed, or shall become incapable of acting or shall be
                  adjudged bankrupt or insolvent, or liquidated or dissolved, or
                  an order is made or an effective resolution is passed to wind

                   (TO BE SIGNED ONLY UPON EXERCISE OF OPTION)

TO:      GRAND ENTERPRISES, INC.

         The Optionee, holder of the attached option, hereby irrevocable elects
to exercise the purchase rights represented by the option for, and to purchase
thereunder, ________________________________ shares of common stock of GRAND
ENTERPRISES, INC., and herewith makes payment therefor, and requests that the
certificate(s) for such shares be delivered to the Optionee at:

______________________________________________________________________________

______________________________________________________________________________

______________________________________________________________________________

         If acquired without registration under the Securities Act of 1933, as
amended ("Securities Act"), the Optionee represents that the Common Stock is
being acquired without a view to, or for, resale in connection with any
distribution thereof without registration or other compliance under the
Securities Act and applicable state statutes, and that the Optionee has no
direct or indirect participation in any such undertaking or in the underwriting
of such an undertaking. The Optionee understands that the Common Stock has not
been registered, but is being acquired by reason of a specific exemption under
the Securities Act as well as under certain state statutes for transactions by
an issuer not involving any public offering and that any disposition of the
Common Stock may, under certain circumstances, be inconsistent with these
exemptions. The Optionee acknowledges that the Common Stock must be held and may
not be sold, transferred, or otherwise disposed of for value unless subsequently
registered under the Securities Act or an exemption from such registration is
available. The Company is under no obligation to register the Common Stock under
the Securities Act, except as provided in the Agreement for the option. The
certificates representing the Common Stock will bear a legend restricting
transfer, except in compliance with applicable federal and state securities
statutes.

         The Optionee agrees and acknowledges that this purported exercise of
the option is conditioned on, and subject to, any compliance with requirements
of applicable federal and state securities laws deemed necessary by the Company.
