Dkfm. Fritz Froehlich, (c) Judith B. Keyes Trust, (d) Jonathan M. Keyes Trust,

Bleyleben, (1) Salomon Smith Barney Custodian FBO Brian E. Boyle IRA (67665812)
and (m) Torrence C. Harder, more fully described on Annex A hereto
(collectively, the "Notes") and (ii) the Fourth Amended and Restated Credit
Agreement (as amended, the "Credit Agreement"), made as of August 22, 2000, by
and among Leasecomm Corporation, a Massachusetts corporation (the "Borrower"),
Fleet National Bank, a national banking association ("Fleet"), the other
financial institutions from time to time party thereto (together with Fleet, the
"Lenders") and Fleet, as agent for the Lenders (the "Agent"). Each capitalized
term used herein without definition and defined in the Notes shall have the same
meaning herein as set forth in the Notes.

     2.   Pursuant to that certain Fourth Amended and Restated Guaranty, dated
as of August 22, 2000 (the "Guaranty"), the Company has guaranteed all of the
Obligations (as defined in the Credit Agreement) of the Borrower under the
Credit Agreement and other Loan Documents (as defined in the Credit Agreement)
(the obligations of the Company under the Guaranty referred to herein as the
"Guaranteed Obligations").

     3.   In order to induce the Lenders to enter into the Second Amendment to
the Credit Agreement, the Company and each of the undersigned holders of the
Notes hereby confirms, acknowledges and agrees as follows (it being understood
that each holder is so confirming, acknowledging and agreeing only as to itself
and the Note(s) held by such holder):

          (a)  The Guaranteed Obligations, whether contingent or liquidated,
     constitute "Senior Indebtedness" under the Notes and the Agent and the
     Lenders shall be entitled to the benefit of the subordination provisions
     contained in the Notes.




          (b)  Notwithstanding anything to the contrary contained in the Notes,
     no payment of principal shall be made with respect to any of the Notes
     until all of the Obligations (as defined in the Credit Agreement) have been
     paid in full, in cash.

          (c)  In addition to and without limiting the Section in each of the
     Notes entitled "Permitted Payments of Note", if prior to the time of any
     regularly scheduled payment under any of the Notes, the Agent has delivered
     to the Company written notice of any Event of Default (as defined the
     Credit Agreement) under the Credit Agreement or any of the other Loan
     Documents (as defined in the Credit Agreement), other than with respect to
     a payment default referred to in the Section in each of the Notes entitled
     "Permitted Payments of Note", no regularly scheduled payments under the
     Notes shall be made commencing on the date of such notice and ending 180
     days thereafter.

          (d)  The Note held by each holder as indicated on Annex A hereto has
     not been amended or modified since the date of the issuance thereof. Each
     holder of a Note will not consent to any amendment or modification of its
     Note, will not sell or transfer such Note and will not consent to or accept
     any prepayment, redemption or purchase of such Note by the Company, in each
     case, without the prior written consent of the Agent.
