Ladies and Gentlemen:

         Reference is made to that certain Note Purchase Agreement dated as of
January 21, 1998 (as amended from time to time, the "NOTE AGREEMENT") between
Corrpro Companies, Inc., an Ohio corporation (the "COMPANY") and The Prudential
Insurance Company of America ("PRUDENTIAL"), pursuant to which the Company
issued and sold its 7.60% Senior Notes due January 15, 2008 in the original
aggregate principal amount of $30,000,000 (the "Notes"). Capitalized terms used
herein and not otherwise defined herein shall have the meanings assigned to such
terms in the Note Agreement.

         Pursuant to the request of the Company and in accordance with the
provisions of paragraph 11C of the Note Agreement, the Company and the
undersigned holders of the Notes executing this letter agree as follows:

         SECTION 1. AMENDMENTS TO NOTE AGREEMENT. From and after the date this
letter becomes effective, the Note Agreement is amended as follows:

         1.1 Paragraph 4B of the Note Agreement is amended by (a) renumbering
the existing paragraph 4B as "4B(1)" and (b) adding a new paragraph 4B(2)
thereto which shall read as follows:

         "4B(2).   OPTIONAL PREPAYMENT WITHOUT YIELD MAINTENANCE AMOUNT.
         (a) In addition to all other payments required hereunder, the Company
         shall prepay the Aggregate Total Outstandings and the aggregate unpaid
         principal amount of the Notes, on a pro rata basis, by an amount equal
         to (a) 100% of the Net Cash Proceeds of any Subordinated Indebtedness
         or similar obligation incurred at any time by the Company or any
         Guarantor, and (b) 100% of the Net Cash Proceeds of any capital
         contribution to the Company or any of its Subsidiaries (other than a
         capital contribution by the Company or any Subsidiary) or issuance of
         any capital stock of the Company (other than any issuance by the
         Company in connection with any employee stock purchase plans or any
         stock option plans).

         (b)  The Company shall give Prudential written notice of the receipt of
              any Net Cash Proceeds described in subparagraph (a) above within
              five Business Days of such receipt. Such notice shall contain and
              constitute an offer to prepay, without Yield Maintenance Amount,
              to each holder of the Notes the amounts described in paragraph (a)
              above. Prudential may accept the offer to prepay pursuant to this
              paragraph 4B(2) by causing a notice of such acceptance to be
              delivered to the Company within ten (10) Business Days after
              receipt of the notice described in the preceding sentence. A
              failure by Prudential to so respond to an offer to prepay made
              pursuant to this paragraph 4B(2) shall be deemed to constitute a
              rejection of such offer by Prudential. Prepayments by the Company
              pursuant to this paragraph 4B(2) shall be made within three (3)
              Business Days of the date of Prudential's acceptance of the offer
              to prepay hereunder."

         1.2 Paragraphs 4D and 4E of the Agreement are amended to delete the
phrase "4A or 4B" and replace each such phrase with "4A, 4B(1) or 4B(2)".

         before March 31, 2001, and (iii) 3.25 to 1.00 at any time after March
         31, 2001."

         1.5 Paragraph 6A(4) of the Note Agreement is amended in its entirety
to read as follows:
