February 13, 2003



Mr. Bob Ariniello
Vice President - Media
Exabyte Corporation
1685 38th Street
Boulder, CO 80301

Dear Bob:

This letter will confirm the mutual agreement between Exabyte Corporation ("Exabyte") and the Media and Application Solutions of Sony Electronics Inc. ("Sony) to extend the term of the April 1, 1995 Purchase Agreement ("Purchase Agreement") through September 30, 2003. The "Extension Term" shall refer to the period between 1/1/03 and 9/30/03.

Buffer Inventory

Exabyte has requested that Sony establish a "buffer" inventory of Exabyte-branded Product ("Buffer Inventory"). Sony is willing to do so, subject to the following conditions:

1)       Sony owns all right and title to the Buffer Inventory until same is transferred to Exabyte in accordance 
                  with the Purchase Agreement;

2)       Sony and Exabyte will mutually determine, the quantities and product mixof the Buffer Inventory;

3)       In the event that Exabyte defaults under the Agreement or any Sony credit requirements and suchdefault 
                  is not cured within [...***...] days or Exabyte otherwise indicates that it is unable or unwilling to 
                  purchase the Buffer Inventory within a reasonable timeframe, Sony shall have the right to sell the Buffer 
                  Inventory or otherwise dispose of it as it sees fit. In such case, Exabyte shall remain liable to the 
                  purchaser for any warranties that may be extended by Exabyte with the Product; Sony shall remain liable 
                  to Exabyte per any applicable warranty provision of the Purchase Agreement.

4)       Exabyte agrees to provide Sony with immediate notice in the event it determines that it will not be able to 
                  purchase the Buffer Inventory or that the Buffer Inventory should be decreased.

5)       In the event that Sony exercises its right to sell the Buffer Inventory, Sony shall credit against Exabyte's 
                  Accounts Receivables, the difference between the amount it collects for the Buffer Inventory ([...***...]) 
                  less [...***...] percent ([...***...]%) for freight and administration, less Sony's then-current price to 
                  Exabyte.

Supply of M-2

Sony agrees to purchase and Exabyte agrees to supply a maximum of [...***...] units per month of Sony-branded M-2 media at a cost of $[...***...]/unit, subject to the execution of an appropriate, mutually agreed upon, Supply Agreement. The Supply Agreement shall contain, among other things, a right of offset for Sony and a provision that said purchases shall be paid by credit memo issued to Exabyte's Accounts Receivable account, to the extent there is an outstanding Accounts Receivables balance. Notwithstanding the foregoing, Sony shall have up to [...***...] days from the date of invoice payment for any such purchases.

VXA Format

Exabyte and Sony acknowledge and reconfirm the April 1998 MOU between Ecrix Corporation and Sony Corporation as further clarified by subsequent letter agreements between those parties as joint owners of the VXA format. In addition, Exabyte agrees to work in good faith towards timely qualification of Sony- produced VXA-2 media for inclusion in the OEM Private Label Sales Agreement discussed below. Exabyte will assist Sony to determine optimal timing to introduction of Sony-branded VXA-1 and VXA-2 media.

The August 1, 1998 OEM Private Label Sales Agreement between Sony Electronics Inc. and Ecrix Corporation is acknowledged and incorporated herein by reference with the following amendments:

1.   The "Seller" shall mean Sony and the "Buyer" shall mean Exabyte.

2.   In Section 1(d), the second sentence is replaced with "[...***...]"

3.   In Section 16, the first sentence is replaced with "The Term of this Agreement shall be from August 
                        1, 2002 through September 30, 2003".

Credit Matters

Sony will continue to examine Exabyte's financial condition as quarterly financial results are released. Sony will adjust the terms of Exabyte's credit line at its discretion in accordance with its ordinary and customary credit policies and procedures. I believe this letter accurately reflects the conversations we've had on these topics. Please indicate Exabyte's agreement by signing below.

Thank you for your assistance.

Best Regards

FOR VALUE RECEIVED, the undersigned, Exabyte Corporation (hereinafter "Debtor") having its principal office at 1685 38th St. Boulder, Co 80301, promises to pay to the order of Sony Electronics Inc.

(b)       the filing by or against Debtor or any proceeding under any bankruptcy, reorganization, arrangement of debt,

(f)       the dissolution, merger, consolidation or reorganization of Debtor;

then, in any such event, the holder hereof may declare the entire principal amount hereof, together with accrued and unpaid interest thereon, immediately due and payable and the same shall forthwith become due and payable without presentment, demand, protest or other notice of any kind, all of which are expressly waived. In addition to any other interest or principal amount due hereunder, interest on the indebtedness evidenced by this Note on any overdue amount or after default or maturity shall be due and payable at the rate of [...***...]% per month until fully paid. In no event shall said rate be greater than the maximum rate of interest permissible under applicable law.

The Debtor irrevocably authorizes and empowers any prothonotary, clerk or attorney of any court of record to appear and to waive the issuance and service of process and to confess and enter judgment for all sums which may be owed from time to time to Sony by the Debtor, after default hereunder, against such Debtor in favor of Sony at any time for all or any part of the total amount of the obligation then due hereunder, with or without declaration, without stay of execution, with costs of suit and attorneys' fees. The authority hereinabove granted shall not be exhausted by one exercise hereof, but judgment may be confessed as aforesaid from time to time and as often as any sum or sums shall be due hereunder.
