     FOR VALUE RECEIVED, Exabyte Corporation, a Delaware corporation (the
"Company"), hereby promises to pay to the order of           ("Payee"), in the
manner and at the place hereinafter provided, the principal Face Amount of
          Dollars ($     ), on or before December 31, 2001 (the "Stated Maturity
Date"), subject to earlier satisfaction as provided in Section 1(c) and
extension as provided in Section 2(a). The Company also promises to pay interest
on the unpaid amount hereof at the rate and in the manner hereinafter provided.
This Note (the "Note") is issued as of            , 2001 (the "Original Issue
Date") pursuant to a Loan and Security Agreement, dated August 22, 2001, between
the Company, Payee and the other lenders named therein (the "Loan Agreement").
The Company's obligations evidenced by this Note are secured by the Collateral
(as defined in the Loan Agreement). The Holder of this Note shall be entitled to
the rights and privileges set forth herein and in the Loan Agreement. See
Section 7 of this Note for definitions used herein.

SECTION 1. Interest and Principal.

     (a) Payment.  The Company shall pay interest ("Interest") on the unpaid
principal Face Amount of this Note from the Original Issue Date at the rate (the
"Interest Rate") equal to 12.0% per annum (computed on the basis of a 360-day
year and the actual number of days elapsed), compounded quarterly. The Interest
Rate shall be subject to adjustment in accordance with Section 1(b) below.
Interest on this Note shall accrue from and after the Original Issue Date and,
except as provided in the immediately succeeding sentence, shall be payable on
the date which the principal of this Note becomes due and payable, whether at
the Stated Maturity Date or by declaration of acceleration, call for redemption,
acceleration pursuant to Section 6 or otherwise (collectively, "Maturity"). If
the Stated Maturity Date of the Note is extended pursuant to Section 2(a) hereof
upon termination of the Merger Agreement, accrued Interest on this Note shall be
payable quarterly on the last day of each March, June, September and December
(commencing at the end of the quarter during which the Merger Agreement was
terminated) and at Maturity. Principal and Interest shall be paid by wire
transfer of immediately available funds to the account designated by the Holder.
All payments hereunder shall be credited first to Interest.

     (b) Adjustments.  In addition to any other remedies it may have, in the
event that (i) any Event of Default (as defined in the Loan Agreement) shall
have occurred and be continuing or (ii) the Company shall at any time have
defaulted in any of its obligations under the Note, which default shall
constitute an

                                        1
<PAGE>   2

Event of Default under Section 5 hereof, then the Interest Rate shall be
increased by an additional 6.0% per annum, from the date such default occurred
until the date such default has been cured. The Interest Rate shall be further
increased by an additional 1.0% per annum for each 90-day period that the Event
of Default continues without cure. An increase in the Interest Rate pursuant to
this paragraph shall not be in lieu of any right or remedy of the Holder
regarding, or constitute a waiver of, any occurrence described in the first
sentence hereof.

     (c) Credit Against Series H Purchase Price.  On the Closing Date (as
defined in the Merger Agreement), the then outstanding principal amount of this
Note and all accrued and unpaid Interest (including Additional Interest) thereon
shall be credited against Payee's total purchase price for the shares of the
Company's Series H Preferred Stock which Payee is purchasing under the Merger
Agreement. Upon such credit against the purchase price and issuance of the
requisite number of shares of Series H Preferred Stock to Payee therefor,
principal and accrued Interest under this Note shall be deemed paid to the full
amount of such credit.

SECTION 2. Conversion or Extension.

     (a) Conversion Events.  Subject to the provisions hereinafter set forth,
all of the principal amount of this Note and accrued Interest thereon shall be
convertible at the option of the Holder thereof into fully paid and
nonassessable shares of Common Stock:

          (i) for a period of thirty (30) days following any termination by
     Ecrix Corporation ("Ecrix") of the Merger Agreement, for any reason other
     than the intentional breach of the Merger Agreement by the Company; or

          (ii) for a period of thirty (30) days following any termination of the
     Merger Agreement by the Company as a result of the intentional breach of
     the Merger Agreement by Ecrix.

     The events set forth in Sections 2(a)(i) and (ii) are defined as
     "Conversion Events." The number of shares of Common Stock to be issued upon
     conversion of the Note (the "Conversion Shares") shall be equal to one (1)
     share of Common Stock for each $.80 in principal amount of the Note and
     accrued Interest thereon being converted (the "Conversion Amount"), subject
     to adjustment from time to time pursuant to paragraph (f) of this Section
     2. If Holder does not elect to convert the Note into Common Stock as
     provided herein within thirty (30) days after the occurrence of a
     Conversion Event, then the Stated Maturity Date shall be automatically
     extended to August 22, 2002 and the Interest Rate on the Note shall
     increase to 15% as of the termination date of the Merger Agreement and
     shall continue to increase by an additional 1.0% per annum for each 90-day
     period until the Maturity Date. If both (x) the Merger has not been
     consummated by December 31, 2001 and (y) the Merger Agreement has not been
     terminated on or prior to that date, then the Stated Maturity Date shall be
     automatically extended to the earlier to occur of (I) the date the Merger
     is consummated or (II) the date the Merger Agreement is terminated.

     (b) Procedures.  Conversion of this Note may be effected by the Holder upon
the surrender to the Company at the principal office of the Company or at the
office of any agent or agents of the Company, as may be designated by the
Company, of the Note to be converted accompanied by a written notice stating
that such Holder elects to convert the entire Face Amount of such Note in
accordance with the provisions of this Section 2 and specifying the name or
names in which such Holder wishes the certificate or certificates for Common
Stock to be issued. In case such notice shall specify a name or names other than
that of such Holder, such notice shall be accompanied by payment of all transfer
Taxes payable upon the issuance of Common Stock in such name or names and an
opinion of counsel satisfactory to the Company that the transfer of the Note may
be made without registration under the Securities Act or any applicable state
securities laws. Other than such Taxes for transfers to other Persons, the
Company will pay any and all issue and other Taxes (other than Taxes based on
income) that may be payable in respect of any issue or delivery of Common Stock
on conversion of the Note pursuant hereto. As promptly as practicable, after the
surrender of such Note and the receipt of such notice relating thereto and, if
applicable, payment of all transfer Taxes for transfers to other Persons (or the
demonstration to the satisfaction of the Company that
                                        2
<PAGE>   3

such Taxes have been paid), the Company shall deliver or cause to be delivered
certificates representing the number of validly issued, fully paid and
nonassessable Common Stock to which the Holder of the Note being converted shall
be entitled as the Conversion Amount. Such conversion shall be deemed to have
been made at the close of business on the date of giving such notice and of such
surrender of the Note to be converted so that the rights of the Holder thereof
as to the amount being converted shall cease except for the right to receive
shares of Common Stock in accordance herewith, and the Person entitled to
receive the Common Stock shall be treated for all purposes as having become the
record holder of such Common Stock at such time. The Company shall not be
required to convert, and no surrender of the Note shall be effective for that
purpose, while the transfer books of the Company for the Common Stock are closed
for any purpose (but not for any period in excess of ten calendar days); but the
surrender of the Note for conversion during any period while such books are so
closed shall become effective for conversion immediately upon the reopening of
such books, as if the conversion had been made on the date such Note was
surrendered, and at the Conversion Ratio in effect on the date of such
surrender.

     (c) Fractional Shares.  No fractional shares shall be issued upon any
conversion of the Note. In lieu thereof, the Company shall round up any
fractional share of its Common Stock to which the Holder shall be entitled to
receive pursuant to this Note to the next highest whole share.

     (d) Reservation of Common Stock.  The Company shall at all times reserve
and keep available for issuance upon the conversion of the Note, free from any
preemptive rights, such number of its authorized but unissued shares of Common
Stock as will from time to time be sufficient to permit the conversion of any
portion of the Note remaining outstanding, and shall take all action required to
increase the authorized number of shares of Common Stock if necessary to permit
the conversion of the Note.

     (e) Anti-dilution Adjustments.  The Conversion Amount will be subject to
adjustment from time to time as follows:

          (1) In case the Company shall at any time or from time to time after
     the Original Issue Date (A) pay a dividend, or make a distribution, on the
     outstanding Common Stock in shares of Common Stock, (B) subdivide the
     outstanding Common Stock, (C) combine the outstanding Common Stock into a
     smaller number of shares or (D) issue by reclassification of the Common
     Stock any shares of Capital Stock of the Company, then, and in each such
     case, the Conversion Amount in effect immediately prior to such event or
     the record date therefor, whichever is earlier, shall be adjusted so that
     the Holder of any Notes thereafter surrendered for conversion shall be
     entitled to receive the number of shares of Common Stock or other
     securities of the Company which such Holder would have owned or have been
     entitled to receive after the happening of any of the events described
     above, had such Notes been surrendered for conversion immediately prior to
     the happening of such event or the record date therefor, whichever is
     earlier. An adjustment made pursuant to this clause (1) shall become
     effective (x) in the case of any such dividend or distribution, immediately
     after the close of business on the record date for the determination of
     holders of Common Stock entitled to receive such dividend or distribution,
     or (y) in the case of such subdivision, reclassification or combination,
     immediately after the close of business on the day upon which such
     corporate action becomes effective.

          (2) If at any time, as a result of: (i) a capital reorganization or
     reclassification or (ii) a merger or consolidation of the Company with
     another corporation (whether or not the Company is the surviving
     corporation), the Common Stock issuable upon the conversion of this Note
     shall be changed into or exchanged for the same or a different number of
     shares of any class or classes of stock of the Company or any other
     corporation, or other securities convertible into such shares, then, as a
     part of such reorganization, reclassification, merger or consolidation,
     appropriate adjustments shall be made in the conversion rights of this
     Note, so that: (A) the holder of this Note shall thereafter be entitled to
     receive, upon conversion of this Note, the kind and amount of shares of
     stock, other securities, money and property which such holder would have
     received at the time of such capital reorganization, reclassification,
     merger, or consolidation, if this Note had been converted immediately prior
     to such capital reorganization, reclassification, merger, or consolidation,
     and (B) the conversion rights of this

                                        3
<PAGE>   4

     Note shall thereafter be adjusted on terms as nearly equivalent as may be
     practicable to the adjustments theretofore provided in this Note.

          (3) The Conversion Amount shall be proportionally adjusted upon any
     transfer, assignment or subdivision permitted hereunder of less than all of
     the Face Amount of this Note such that upon the occurrence of any
     Conversion Event, the number of fully paid and nonassessable shares of
     Common Stock issuable upon the conversion of any resulting note or notes
     shall be equal to the Conversion Amount in effect immediately prior to such
     transfer, assignment or subdivision multiplied by the ratio that the
     principal face amount of such resulting note or notes bears to the Face
     Amount.

          (4) Anything in this paragraph (e) to the contrary notwithstanding,
     the Company shall not be required to give effect to any adjustment in the
     Conversion Amount unless and until the net effect of one or more
     adjustments (each of which shall be carried forward), determined as above
     provided, shall have resulted in a change of the Conversion Amount by at
     least one one-hundredth of one share of Common Stock, and when the
     cumulative net effect of more than one adjustment so determined shall be to
     change the Conversion Amount by a least one one-hundredth of one share of
     Common Stock, such change in Conversion Amount shall thereupon be given
     effect.

          (5) If the Company shall take a record of the holders of its Common
     Stock for the purpose of entitling them to receive a dividend or other
     distribution, and shall thereafter and before the distribution to
     stockholders thereof legally abandon its plan to pay or deliver such
     dividend or distribution, then thereafter no adjustment in the number of
     shares of Common Stock issuable upon exercise of the right of conversion
     granted by this paragraph (e) or in the Conversion Ratio then in effect
     shall be required by reason of the taking of such record.

     (f) Notice of Certain Events.  In case at any time or from time to time the
Company shall pay any dividend or make any other distribution to the holders of
its Common Stock, or shall offer for subscription pro rata to the holders of its
Common Stock any additional shares of stock of any class or any other right, or
there shall be any capital reorganization or reclassification of the Common
Stock of the Company or merger of the Company with or into another corporation,
or any sale or conveyance to another corporation of the property of the Company
as an entirety or substantially as an entirety, or there shall be contemplated
or proposed by the Company or its Board of Directors, or there shall be a
voluntary or involuntary dissolution, liquidation or winding up of the Company,
then, in any one or more of said cases the Company shall give at least twenty
days prior written notice (five days after the date of mailing of such notice
shall be deemed to be the time of giving thereof) to the registered Holder of
the Note at the address(es) as shown on the books of the Company as of the date
on which (i) the books of the Company shall close or a record shall be taken for
such stock dividend, distribution or subscription rights (ii) such
reorganization, reclassification, merger, sale or conveyance, dissolution,
liquidation or winding up shall take place, as the case may be. Such notice
shall also specify the date as of which the holders of the Common Stock of
record shall participate in said dividend, distribution or subscription rights
or shall be entitled to exchange their Common Stock for securities or other
property deliverable upon such reorganization, reclassification, merger, sale or
conveyance or participate in such dissolution, liquidation or winding up, as the
case may be, or the latest date on which the Holder of the Note may elect to
convert this Note into Common Stock pursuant to the provisions of this Section
2.

     (g) Notice of Adjustments.  Upon any adjustment of the Conversion Amount
then in effect and any increase or decrease in the number of shares of Common
Stock issuable upon the operation of the conversion provisions set forth in
Section 2 hereof, then, and in each such case, the Company shall promptly
deliver to the transfer agent of the Common Stock, if any, a certificate signed
by the President and by the Treasurer or an Assistant Treasurer or the Secretary
or an Assistant Secretary of the Company setting forth in reasonable detail the
event requiring the adjustment and the method by which such adjustment was
calculated and specifying the Conversion Amount then in effect following such
adjustment and the increased or decreased number of shares issuable upon the
conversion set forth in Section 2 hereof. The Company shall also promptly after
the making of such adjustment give written notice to the registered Holders of
the Notes at the address of each Holder as shown on the books of the Company,

                                        4
<PAGE>   5

which notice shall state the Conversion Amount then in effect, as adjusted, and
the increased or decreased number of shares issuable upon the exercise of the
right of conversion granted by Section 2 hereof, and shall set forth in
reasonable detail the method of calculation of each and a brief statement of the
facts requiring such adjustment. Where appropriate, such notice to Holders of
the Notes may be given in advance and included as part of the notice required
under the provisions of Section 2(f) hereof.

     (h) Further Actions.  The Company will not, through any reorganization,
transfer of assets, consolidation, merger, dissolution, issue or sale of
securities or any other action, avoid or seek to avoid or fail to observe or
perform any of the terms to be observed or performed hereunder by the Company,
but will at all times in good faith assist in the carrying out of all the
provisions of this Section 2 and in the taking of all such action as may be
necessary or appropriate in order to protect the conversion rights of the Holder
of the Note against impairment.

SECTION 3. Seniority; Subordination.

     (a) Senior Debt.  Anything in this Note to the contrary notwithstanding,
the Company covenants and agrees, and Payee and, by its acceptance of this Note,

Additional Interest) on this Note as and when the same shall become due in
accordance with its terms, or is intended to or shall affect the relative rights
against the Company of Payee or such subsequent Holder and creditors of the
Company. The failure to make a payment on account of this Note by reason of any
provision of this Section 3 shall not be construed as preventing the occurrence
of an Event of Default, nor shall anything herein prevent Payee or any
subsequent Holder from exercising all remedies otherwise permitted by applicable
law upon default under this Note.

     (c) Subordination.  This Note shall be subject to the subordination
provisions set forth in that certain Subordination and Intercreditor Agreement
dated as of August 22, 2001 among Congress Financial Corporation, the Company,

that it may lawfully do so) that it shall not at any time insist upon, plead, or
in any manner whatsoever claim or take the benefit or advantage of, any stay,
extension or usury law or other laws which would prohibit or forgive the Company
from paying all or any portion of the principal of or Interest (including any
Additional Interest) on the Note as contemplated herein, wherever enacted, now
or at any time hereafter in force, or which may affect the covenants or the
performance of the Note.

     (c) Maintenance of Office or Agency.  The Company shall maintain in
Boulder, Colorado an office or agency where Notes may be presented or
surrendered for payment, where Notes may be surrendered for registration of
transfer or exchange, where Notes may be surrendered for conversion and where
notices and demands to or upon the Company in respect of the Notes may be
served. The Company shall give prompt written notice to the Holder of the
location, and any change in the location, of such office or agency. The Company
may also from time to time designate one or more other offices or agencies (in
or outside Boulder, Colorado) where the Notes may be presented or surrendered
for any or all such purposes and may from time to time rescind such
designations; provided, however, that no such designation or rescission shall in
any manner relieve the Company of its obligation to maintain an office or agency
in the United

                                        5
<PAGE>   6

discretion provided that such amount does not exceed $2,000,000 of Class C
Preferred Stock (the "Class C Stock") of Ecrix on the same terms and conditions
and with such other rights and privileges as may be negotiated by the parties
purchasing a majority of the Class C Stock. It is anticipated that the closing
of the Class C Stock round will occur on or before November 1, 1997, or within
90 days thereafter.

parties or by one party using any Confidential Information of the other party,
the rights shall be jointly owned by the parties, subject to the limitations set
forth in this Agreement. The parties agree to cooperate with each other to file
applications for patents or other intellectual property rights arising out of
such work. All expenses and charges necessary for the filing and prosecution of
such applications, issuance and maintenance fees for such rights shall be
equally borne by the parties.

XIII. MUTUAL LICENSE

     Each party grants to the other party a non-exclusive and paid-up license
under its intellectual property rights (including pre-existing rights) to
conduct the activities under the terms of and during the term of this Agreement.

XIV. EXCHANGE OF TECHNICAL INFORMATION; MODIFICATIONS; RELATED PRODUCT
     DEVELOPMENT; COMMUNICATION AND LIAISON; REPORTING

     A. Each party acknowledges that the purpose of this Agreement is to
establish a long-term, mutually beneficial working relationship in the joint

the Product may involve technical challenges. As such, each party agrees to (i)
provide the other with reasonable consultation services with regard to the
design and development of the components for which it has responsibility as set
forth in Sections IV and V above; and (ii) to make all reasonable efforts to
improve, enhance and modify the Product.

     B. The parties recognize that either Ecrix or AIWA may develop additional
products for which a joint development effort would also be mutually beneficial.
In

<PAGE>   6

particular, the parties have begun initial discussions about the development of
an autoloader which would be designed to operate with the Product. The parties
agree to negotiate in good faith appropriate addenda to incorporate such
additional products under this Agreement.

     C. In order to assure a smooth and optimal joint development between the
parties, each party will, from time to time during the term of this Agreement,
upon the written request of the other party and with the least possible delay,
provide the other party with technical assistance and disclose specific
information with respect to the development, design, manufacture and assembly of
the Product, as required for each party's responsibilities as described in
Sections IV and V above, based on their mutual competencies and in full
compliance with the terms of Exhibit D (Non-Disclosure Agreement) attached
hereto. Such assistance will include but not be limited to, factory visits,
consultation, problem solving meetings and disclosure of technical information
applicable to each party's responsibilities. Each party will provide the other
party with the appropriate expertise, without any charge to the other, in a
timely manner, at the facility site so requested.

     D. Each party shall, from time to time during the term of this Agreement,
dispatch its pertinent engineer(s) to an agreed place, subject to the prior
consent of the other party, to conduct meetings for the purpose of expediting

of the Product. Each party hereto shall bear to its own costs and expenses for
such meetings. Each party further agrees to submit to the other party any
interim reports in English from time to time during the period of joint
development as and when the submitting party considers such reports as
appropriate and conducive for the purpose of the joint development.

XV. CONFIDENTIALITY

     A. Ecrix and AIWA have entered into a Non-Disclosure Agreement dated August
7, 1996, a copy of which is attached as Exhibit D. The parties agree that the
purpose of the parties' disclosures under that Non-Disclosure Agreement is
hereby expanded to include all activities of both parties contemplated by this
Agreement and that the provisions of that Non-Disclosure Agreement shall be
applicable to all Confidential Information disclosed by either party in
connection with such activities.

Exhibits attached hereto, all of which are incorporated herein by reference.

     G. This Agreement is deemed entered into and shall in all respects be
governed by and construed under the laws of Colorado. The parties shall use
their best efforts to settle any matters not expressed in this document by
amicable agreement. If any dispute or difference shall arise between the parties
concerning the construction of this Agreement or the rights or obligations of
either party, the parties shall strive to settle the same amicably, but if they
are unable to do so, the dispute or difference shall be finally settled by
arbitration pursuant to the Japan-American Trade Arbitration Agreement of
September 16, 1952, by which each party agrees to be bound, and the award of the
arbitration shall be final. The place of arbitration shall be determined by the
identity of the party demanding arbitration. If AIWA demands arbitration, the
place of arbitration shall be Boulder, Colorado, U.S.A. If Ecrix demands
arbitration, the place shall be Tokyo, Japan. On all matters and procedures
concerned with arbitration other than selection of the place of arbitration, as
agreed above, the provisions of the Japan-American Trade Arbitration Agreement
of September 16, 1952 shall apply. The award of the arbitration shall be final
and may be entered into and enforced by any court having jurisdiction. The cost
of the arbitration proceeding and attorneys' fees and expenses of the parties
shall be allocated as directed by the arbitrators.

     H. The parties hereto are independent contractors and nothing contained in
this Agreement shall be deemed or construed to create a partnership, joint
venture, employment, franchise, or agency relationship between the parties.
Ecrix and AIWA acknowledge and agree that they do not have the authority to make
any representation to any third party, directly or indirectly, indicating that
they have the authority to act for or on behalf of the other party or to
obligate the other party in any manner whatever.

     I. The parties agree to comply with all applicable Japanese, United States
Federal and State laws and regulations related to the export of technical data
under this Agreement, and obtain all required governmental approvals prior to
export.

     IN WITNESS WHEREOF, the parties hereto have executed this Agreement as of
the date and year first above written.
