EXHIBIT A

REPLACEMENT REVOLVING CREDIT NOTE

FOR VALUE RECEIVED, the undersigned, MOD-PAC CORP., a New York corporation (“Borrower”) hereby unconditionally promises to pay, on or before the Revolving Credit Maturity Date, to the order of MANUFACTURERS AND TRADERS TRUST COMPANY (“Lender”) at Lender’s office at One Fountain Plaza, Buffalo, New York 14203, or at the holder’s option, at such other place as may be designated by the holder, in lawful money of the United States of America, a principal sum equal to the lesser of THREE MILLION AND 00/100 DOLLARS ($3,000,000.00) or the aggregate unpaid principal amount of all Revolving Loans made by Lender to the Borrower from time to time under a Revolving Credit Agreement, dated as of June 9, 2010, between the Borrower and the Lender, as the same may from time to time be amended, supplemented or otherwise modified (“Revolving Credit Agreement”) as evidenced by the inscriptions made on the schedule attached hereto, or any continuation thereof (“Schedule”). The Borrower further promise to pay interest on the unpaid principal amount hereof from time to time at the rates and on the dates determined in accordance with the Revolving Credit Agreement. All capitalized terms used herein and not otherwise defined herein shall have the meanings specified in the Revolving Credit Agreement.

The Lender and each holder of this Note are authorized to inscribe on the Schedule the type of Revolving Loan, the date of the making of each Revolving Loan, the amount of each Revolving Loan, all payments on account of principal and the aggregate outstanding principal balance of this Note from time to time unpaid. Each entry set forth on the Schedule shall be prima facie evidence of the facts so set forth. No failure by the Lender or any holder of this Note to make, and no error in making, any inscriptions on the Schedule shall affect Borrower’s obligation to repay the full principal amount loaned to or for the account of the Borrower, or the Borrower’s obligation to pay interest thereon at the agreed upon rate.

If any payment on this Note becomes due and payable on a day other than a Business Day, the maturity thereof shall be extended to the next succeeding Business Day, and the Borrower will pay interest thereon at the then applicable rate until the date of actual receipt of such installment by the holder of this Note.

No failure by the holder to exercise, and no delay in exercising, any right or power hereunder shall operate as a waiver thereof, nor shall any single or partial exercise by the holder of any right or powers hereunder preclude any other or further exercise thereof or the exercise of any other right or power. The rights and remedies of the holder as herein specified are cumulative and not exclusive of any other rights or remedies which the holder may otherwise have.

No modification, rescission, waiver, release or amendment of any provision of this Note shall be made except by a written agreement subscribed by duly authorized officer of the Borrower and the holder hereof.

Borrower waives diligence, presentment, protest and demand, and also notice of protest, demand, dishonor and nonpayment of this Note.

This Note evidences a borrowing under the Revolving Credit Agreement to which reference is hereby made with respect to collateral, interest rate options and periods, mandatory and voluntary prepayments, and rights of acceleration of the principal hereof on the occurrence of certain events.

Borrower agrees to pay on demand all reasonable costs and expenses incurred by the holder in enforcing this Note or in collecting the indebtedness evidenced hereby, including, without limitation, if the holder retains counsel for any such purpose, reasonable attorneys’ fees and expenses.

This Note shall be construed under, and governed by, the internal laws of the State of New York without regard to principles of conflicts of laws.

The Borrower acknowledges, agrees and understands that this Note is given in replacement of and in substitution for, but not in payment of, a Revolving Credit Note dated June 9, 2010 in the original principal amount of $3,000,000.00 issued by Borrower to the Lender (or its predecessor in interest), as the same may have been amended or modified from time to time (the “Prior Note”), and further, that: (a) the obligations of the Borrower as evidenced by the Prior Note shall continue in full force and effect, as amended and restated by this Note, all of such obligations being hereby ratified and confirmed by the Borrower; (b) any and all liens, pledges, assignments and security interests securing the Borrower’s obligations under the Prior Note shall continue in full force and effect, are hereby ratified and confirmed by the Borrower, and are hereby acknowledged by the Borrower to secure, among other things, all of the Borrower’s obligations to the Lender under this Note, with the same priority, operation and effect as that relating to the obligations under the Prior Note; and (c) nothing herein contained shall be construed to extinguish, release, or discharge, or constitute, create, or effect a novation of, or an agreement to extinguish, the obligations of the Borrower with respect to the indebtedness originally described in the Prior Note or any of the liens, pledges, assignments and security interests securing such obligations.
