EXECUTION COPY

STOCK EXCHANGE AGREEMENT
(SERIES I)

ThisStock Exchange Agreement(this "Agreement") is made and entered into as of April 2, 2004, between Exabyte Corporation, a Delaware corporation (the "Company") and each of the owners of Series I preferred stock ("Series I") of the Company, named on Schedule 1 attached hereto and incorporated herein by reference, who have executed this Agreement (each a "Preferred Holder" and collectively, the "Preferred Holders").

Background

A.	The Preferred Holders wish to exchange their Series I shares for shares of a newly designated series of preferred stock of the Company to be sold in the Private Placement (as defined below), referred to as the "New Series." The Company currently contemplates that the New Series will be called Series AA preferred stock of the Company. However, this Agreement applies to the New Series whatever the final title of such New Series is.

B.	The Company has commenced steps for making and consummating a private placement of the New Series of preferred stock for a total purchase price of up to $20 million and with C.E. Unterberg, Towbin acting as the Company's exclusive financial advisor (the "Private Placement"). The parties acknowledge that this information is currently confidential.

1. EXCHANGE OF SHARES

1.1 Exchange

Subject to the terms and conditions hereof, at the Closing (defined below) each Preferred Holder agrees to exchange the number of Series I shares set forth opposite such Preferred Holder's name on Schedule 1 (the "Tendered Shares"), including any and all related rights, for that number of shares of the New Series (the "Exchange Shares") that is convertible into the same number of shares of Common Stock as the Tendered Shares, assuming for such purpose the accrual of all dividends on the Tendered Shares through December 31, 2004, and the Company agrees to issue the Exchange Shares to such Preferred Holder (the "Exchange"). In connection with the Exchange, the Preferred Holders will receive any warrants or other consideration received by the purchasers of the New Series in the Private Placement on an equal per-share basis. The parties acknowledge and agree that the final terms and conditions of the New Series shall be as set forth in the Certificate of Designation of preferences and terms concerning the New Series prepared and filed with the Delaware Secretary of State in connection with the Private Placement.

1.2 Surrender and Issuance

At or before the Exchange, the Preferred Holders shall surrender, at the offices of the Company as directed, any and all certificates for the Tendered Shares. At the Closing, the Company will issue to each Preferred Holder certificates representing the Exchange Shares issuable to such holder in the Exchange and bearing an appropriate legend referring to the fact that the Exchange Shares were exchanged in reliance upon exemptions from registration provided by the Securities Act of 1933, as amended (the "Securities Act") and rules and regulations promulgated under the Securities Act.

2. CLOSING

The closing of the Exchange (the "Closing") shall take place at the offices of the Company and shall be held (a) concurrently with the consummation of the Private Placement, or (b) if requested by the Company, as soon as practicable (but not more than one business day) after the consummation of the Private Placement. (The date on which the Closing occurs is referred to as the "Closing Date.")
