                          AGREEMENT AND PLAN OF MERGER

         This Agreement and Plan of Merger (this "AGREEMENT") is made and
entered into as of August 22, 2001, by and among Exabyte Corporation, a Delaware
corporation ("PARENT"), Bronco Acquisition, Inc., a Delaware corporation and a
wholly owned subsidiary of Parent ("MERGER SUB"), Ecrix Corporation, a Delaware
corporation (the "COMPANY"), the investors listed on the signature page of this
Agreement (the "INVESTORS") and the lenders listed on the signature pages of
this Agreement (the "LENDERS").

                                    RECITALS

         A.       The Company, Parent and Merger Sub believe it advisable and in
their respective best interests to effect a merger of the Company and Merger Sub
pursuant to this Agreement (the "MERGER").

         B.       The Board of Directors of the Company has approved this
Agreement and the Merger as required by applicable law, and will submit this
Agreement to the Company's stockholders for their approval.

         C.       The Boards of Directors of Parent and Merger Sub and the sole
stockholder of Merger Sub have approved this Agreement and the Merger as
required by applicable law.

                                    AGREEMENT

         In consideration of the terms of this Agreement, the parties hereto
agree as follows:

                                    ARTICLE I
                                   THE MERGER

         1.1      THE MERGER

         Upon the terms and subject to the conditions of this Agreement, at the
Effective Time (as defined in SECTION 1.3) the separate existence of Merger Sub
shall cease and Merger Sub shall be merged with and into the Company, and the
Company shall continue as the surviving corporation in the Merger and a wholly
owned subsidiary of Parent (the Company as the surviving corporation after the
Merger is sometimes referred to herein as the "SURVIVING CORPORATION").

         1.2      THE CLOSING

         Upon the terms and subject to the conditions of this Agreement, the
closing of the Merger (the "Closing") shall take place on the earliest
practicable business day (the "CLOSING DATE"), but not later than the fifth
business day, after the satisfaction or


                                       1
<Page>

waiver of the conditions set forth in ARTICLES VII AND VIII at 10 a.m. local
time at the offices of Holland & Hart LLP, Suite 500, 1050 Walnut Street,
Boulder, CO 80302, or such other date, time or location as Parent and the
Company shall agree.

         1.3      EFFECTIVE DATE AND TIME

         On the Closing Date and upon the terms and subject to the conditions of
this Agreement, the Company and Merger Sub shall cause the appropriate
certificate (the "CERTIFICATE OF MERGER") substantially in the form attached as
EXHIBIT 1.3 complying with the applicable provisions of the Delaware General
Corporate Law ("DGCL") to be properly executed and filed with the Secretary of
State of the State of Delaware (the "DELAWARE SECRETARY OF STATE"). The Merger
shall become effective on the date (the "EFFECTIVE DATE") and at the time (the
"EFFECTIVE TIME") of filing of the Certificate of Merger or at such other time
as may be specified in the Certificate of Merger as filed. If the Delaware
Secretary of State requires any changes in the Certificate of Merger as a
condition to filing or to issuing its certificate to the effect that the Merger
is effective, Parent, Merger Sub and the Company will execute any necessary
revisions incorporating such changes, provided such changes are not materially
inconsistent with and do not result in any material change in the terms of this
Agreement.

         1.4      CERTIFICATE OF INCORPORATION OF THE SURVIVING CORPORATION

         At the Effective Time, the Certificate of Incorporation of Merger Sub
as in effect immediately prior to the Effective Time shall become the
Certificate of Incorporation of the Surviving Corporation, except that the name
of the corporation shall set forth therein shall be changed to the name of the
Company. Thereafter, the Certificate of Incorporation of the Surviving
Corporation may be amended in accordance with its terms and as provided by law.

         1.5      BYLAWS OF THE SURVIVING CORPORATION

         At the Effective Time, the Bylaws of Merger Sub as in effect
immediately prior to the Effective Time shall become the Bylaws of the Surviving
Corporation, except that the name of the corporation set forth therein shall be
changed to the name of the Company. Thereafter, the Bylaws may be amended or
repealed in accordance with their terms and the Certificate of Incorporation of
the Surviving Corporation and as provided by law.

         1.6      EFFECTS OF MERGER

         The Surviving Corporation shall, by virtue of the Merger and in
accordance with the DGCL, possess all the properties and rights and be subject
to all the liabilities of the Company and Merger Sub. From and after the
Effective Time, the Merger shall have all effects provided by applicable law.

         1.7      DIRECTORS AND OFFICERS

         At the Effective Time, the directors of Merger Sub shall continue in
office as the directors of the Surviving Corporation and the officers of the
Merger Sub shall continue in office as the officers of the Surviving
Corporation, and such directors and officers shall hold office in accordance
with and subject to the Certificate of Incorporation and Bylaws of the Surviving
Corporation. At the Effective Time,(i) the number of members of the Board of
Directors of Parent (the "Board") shall be increased to seven (7), (ii) Parent
shall remove or accept the resignations of two members of the Board, and (iii)
the resulting vacancies on the Board shall be filled by the election of G.
Jackson Tankersley, Jr., William J. Almon, Sr. and Juan A. Rodriguez ("COMPANY
DESIGNEES") as directors of Parent, each to serve until the next annual meeting
of stockholders of Parent at which such directorship is up for reelection and
until their successors are elected and qualified. These directors shall be
placed in one or more classes of directors whose staggered terms expire at the
2002, 2003 and 2004 Annual Meetings of stockholders of Parent, respectively.
Except as provided in the last sentence of this Section 1.7 the Parent agrees to
take all action necessary such that the Parent's Board of Directors shall at all
times include three directors (or such greater number of directors as shall
constitute the maximum number of members that represent a numerical minority of
the Board) who are nominated by the Company Designees and included in the slate
of proposed directors put forth by the Parent to its stockholders and
recommended for election in the proxy solicitation materials disseminated by the
Parent. Upon the death, resignation or removal of any Company Designee, Parent
will cause the vacancy to be filled by a subsequent designee recommended by the
remaining Company Designees then serving on the Board. The Company Designees
shall be covered by any directors' and officers' liability insurance maintained
from time to time on the same terms as the other members of the Board and shall
be entitled to the benefit of any indemnification arrangements applicable to
other members of the Board. The Company Designees shall have the right to
receive all fees paid and options and other awards granted and expenses
reimbursed to non-employee directors generally, except that in the event that
any Company Designee shall also be an employee of Parent, such Company Designee
shall only be entitled to receive compensation for his service on the Board of
Directors consistent with the policies of Parent's Board of Directors governing
the compensation of employee directors generally. If at any time, the Investors
shall beneficially own (within the meaning of Rule 13d-3 under the Securities
Exchange Act of 1934, as currently in effect) less than 30% of the then
outstanding voting power of all classes of the Parent's voting securities, the
number of directors that Parent shall be obligated to include on the Board of
Directors pursuant to the fourth sentence of this Section 1.7 shall be reduced
so that the number of Company Designees expressed as a percentage of the entire
Board of Directors is approximately equal to the percentage of the outstanding
voting power then beneficially owned by the Investors rounded to the nearest
whole directorship but in any event not a majority; provided, however that if
the Investors shall beneficially own less than 10% of the outstanding voting
power of all classes of the Parent's voting securities, the number of Company
Designees shall be zero.

         As of the Effective Time, by virtue of the Merger and without any
action on the part of the Company, Merger Sub, Parent or any of their respective
stockholders:

                  (a)      All shares of any class of capital stock of the
Company held by the Parent, Merger Sub or any other subsidiary of the Parent or
held by the Company as treasury shares shall be canceled.

                  (b)      The outstanding shares of preferred stock of the
Company (the "COMPANY PREFERRED STOCK"), other than shares of Company Preferred
Stock for which dissenters' rights are perfected and shares canceled pursuant to
paragraph (a) above, shall be converted into the right to receive up to
9,000,000 shares of Parent's common stock, $0.001 par value per share ("PARENT
COMMON STOCK"), with the exchange ratio for each series of Company Preferred
Stock to be as follows (each, a "COMPANY PREFERRED STOCK EXCHANGE RATIO"):

                           (i)      Each issued and outstanding share of the
         Company's Series D-1 Preferred Stock (other than dissenters shares)
         shall be converted into the right to receive .82400 shares of Parent
         Common Stock (the "SERIES D-1 PREFERRED STOCK EXCHANGE RATIO").

                           (ii)     Each issued and outstanding share of the
         Company's Series D Preferred Stock (other than dissenters shares) shall
         be converted into the right to receive .04857 shares of Parent Common
         Stock.

                           (iii)    Each issued and outstanding share of the

         Stock.

                           (iv)     Each issued and outstanding share of the
         Company's Series B Preferred Stock (other than dissenters shares) shall
         be converted into the right to receive .02371 shares of Parent Common
         Stock.

                           (v)      Each issued and outstanding share of the
         Company's Series A Preferred Stock (other than dissenters shares) shall
         be converted into the right to receive .00952 shares of Parent Common
         Stock.

                  (c)      The outstanding shares of common stock of the Company
(the "COMPANY COMMON STOCK" and together with the Company Preferred Stock, the
"COMPANY CAPITAL STOCK"), other than shares of Company Common Stock for which
dissenters' rights are perfected and shares that are canceled pursuant to
paragraph 1.8.1(a) above, shall be converted into the right to receive a total
of 1,000,000 shares of Parent Common Stock, with each outstanding share of
Company Common Stock


                                       4
<Page>

converted into the right to receive a number of shares of Parent Common Stock
equal to (i) 1,000,000 divided by (ii) the total number of shares of Company
Common Stock outstanding immediately prior to the Effective Time (the "COMPANY
COMMON STOCK EXCHANGE RATIO") provided that the 1,000,000 shares of Parent
Common Stock issuable to holders of the Company Common Stock shall be reduced by
the number of shares of Parent Common Stock attributable to shares of Company
Common Stock for which dissenters' rights have been properly exercised under the
DGCL.

                  (d)      In the event there is any change after the date of
this Agreement to the number of shares of Company Preferred Stock to be
exchanged as a result of the Merger, the applicable Company Preferred Stock
Exchange Ratio shall be appropriately adjusted so that the aggregate number of
shares of Parent Common Stock issuable as a result of the Merger upon conversion
of the Company Preferred Stock shall not exceed 9,000,000 shares (less any
shares otherwise issuable to holders of Company Preferred Stock that have
properly exercised dissenters' rights under the DGCL). The number of shares of
Parent Common Stock shall be appropriately adjusted in the event of a stock
split, stock combination or other similar change in the Parent's Capital Stock
effected prior to Closing.

                  (e)      Each issued and outstanding share of capital stock of
Merger Sub shall be converted into one share of common stock of the Surviving
Corporation.

                  (f)      Each outstanding Option to purchase shares of Company
Common Stock (the "OPTIONS") issued pursuant to the Company's 1998 Incentive
Stock Option Plan and Equity Incentive Plan (the "COMPANY OPTION PLANS"), and
each warrant to purchase shares of the Company's Series B Preferred Stock (the
"WARRANTS"), whether or not vested or exercisable, shall, unless such Option of
Warrant shall have been exercised prior to consummation of the Merger, terminate
by its terms in connection with the Merger. The Board of Directors of the
Company shall take such action or make such determinations as necessary to
terminate the Options and Warrants at the Effective Time of the Merger.
Notwithstanding the foregoing, to the extent any B Warrants are exercised prior
to the Effective Time, the shares of the Company's Series B Preferred Stock
issued upon such exercise shall be converted into shares of Parent Common Stock
in accordance with the applicable Company Preferred Stock Exchange Ratio;
provided, however, that such Company Preferred Stock Exchange Ratio shall be
adjusted to the product of the applicable Company Preferred Stock Exchange Ratio
multiplied by a fraction, (i) the numerator of which shall be the aggregate
number of shares of the Company's Series B Preferred Stock outstanding as of the
date of this Agreement and (ii) the denominator of which shall be the aggregate
number of shares of the Company's Series B Preferred Stock outstanding
immediately prior to the Effective Time. Notwithstanding the foregoing, to the
extent any D-2 Warrants are exercised prior to the Effective Time, the shares of
the Company's Series D-2 Preferred Stock issued upon such exercise shall be
converted into shares of Parent Common Stock in accordance with the Series D-1
Preferred Stock Exchange Ratio; provided, however, that such Series D-1
Preferred Stock Exchange Ratio shall be adjusted to the product of


                                       5
<Page>

the Series D-1 Preferred Stock Exchange Ratio multiplied by a fraction, (i) the
numerator of which shall be the aggregate number of shares of the Company's
Series D-1 Preferred Stock outstanding as of the date of this Agreement and (ii)
the denominator of which shall be the aggregate number of shares of the
Company's Series D-1 Preferred Stock and Series D-2 Preferred Stock outstanding
immediately prior to the Effective Time.

                  (g)      Holders of shares of Company Capital Stock who have
complied with all the requirements for perfecting dissenters' rights, as
required under the DGCL, shall be entitled to their rights under the DGCL with
respect to such shares (the "DISSENTING SHARES"). Notwithstanding the foregoing,
if any holder of Dissenting Shares shall effectively withdraw or lose (through
failure to perfect or otherwise) the right to dissent, then, as of the later of
the Effective Time and the occurrence of such event, such holder's shares shall
automatically be converted into and represent only the right to receive the
shares of Parent Common Stock to which such holder is then entitled under this
Agreement and the DGCL, without interest thereon and upon surrender of the
certificate or certificates representing such shares. Notwithstanding any
provision of this Agreement to the contrary, any Dissenting Shares held by a
stockholder who has perfected dissenter's rights for such shares in accordance
with the DGCL shall not be converted into Parent Common Stock pursuant to this
SECTION 1.8.1.

                  (h)      If, prior to the Effective Time, Parent or the
Company effects a subdivision of its outstanding shares into a greater number of
shares, or a combination of its outstanding shares into a lesser number of
shares, or reorganizes, reclassifies or otherwise changes its outstanding shares
into the same or a different number of shares or other classes, or declares a
dividend on its outstanding shares payable in shares of its capital stock or
securities convertible into shares of its capital stock, then the Company Common
Stock Exchange Ratio and the Company Preferred Stock Exchange Ratios will be
adjusted appropriately so as to maintain the relative proportionate interests of
the holders of shares of Company Capital Stock and the holders of shares of
Parent Common Stock.

                  1.8.2    Exchange of Certificates

                  (a)      As promptly as practicable after the Effective Time,
Parent shall make available to BankBoston, N.A., the "EXCHANGE AGENT," the
certificates representing the whole shares of Parent Common Stock issued
pursuant to Section 1.8.1 in exchange for outstanding shares of Company Capital
Stock.

                  (b)      The Exchange Agent shall mail on or prior to the
Closing Date to each holder of record as of the date 10 business days prior to
the Closing Date of a certificate or certificates which immediately prior to the
Effective Time represented outstanding shares of Company Capital Stock (and as
soon as practicable to stockholders that became holders of Company Capital Stock
subsequent to such date), other than shares to be canceled in accordance with
Section 1.8.1(a), (i) a letter of


                                       6
<Page>

transmittal (the "LETTER OF TRANSMITTAL") in customary form and (ii)
instructions for effecting the surrender of the certificates in exchange for
certificates representing Parent Common Stock. Upon surrender of a certificate
for cancellation to the Exchange Agent or to such other agent or agents as may
be appointed by Parent, together with such Letter of Transmittal, duly executed,
and such other documents as may reasonably be required by the Exchange Agent,
the holder of such certificate shall be entitled to receive in exchange
therefor, by the later of (a) ten business days following the Effective Time and
(b) ten business days following the surrender of such certificate, a certificate
representing that number of whole shares of Parent Common Stock which such
holder has the right to receive pursuant to the provisions of SECTION 1.8.1, and
the certificate so surrendered shall forthwith be canceled.

                  (c)      In the event that any certificates representing
shares of Company Capital Stock shall have been lost, stolen or destroyed, upon
the making of an affidavit of that fact by the stockholder claiming such
certificate to be lost, stolen or destroyed, Parent shall issue in exchange for
such lost, stolen or destroyed certificate the shares of Parent Common Stock
that such stockholder is entitled to receive pursuant to SECTION 1.8.1;
provided, however, that Parent may, in its discretion and as a condition
precedent to the issuance thereof, require such stockholder to provide Parent
with a reasonable and customary indemnity agreement against any claim that may
be made against Parent with respect to the certificate alleged to have been
lost, stolen or destroyed.

                  (d)      The shares of Parent Common Stock that each
stockholder of the Company shall be entitled to receive pursuant to the Merger
shall be deemed to have been issued at the Effective Time. If the Merger
Consideration (or any portion thereof) is to be delivered to any person other
than the person in whose name the certificate or certificates representing
shares of Company Capital Stock surrendered in exchange therefor are registered,
it shall be a condition to such exchange that the person requesting such
exchange pay to Parent any transfer or other taxes required by reason of the
payment of the Merger Consideration to a person other than the registered holder
of the certificate or certificates so surrendered, or shall establish to the
satisfaction of Parent that such tax has been paid or is not applicable.
Notwithstanding anything to the contrary, neither Parent nor any other party
hereto shall be liable to a holder of shares of Company Capital Stock for any
Merger Consideration delivered to a public official pursuant to applicable law,
including abandoned property, escheat and similar laws to the extent required
under law to be so delivered.

                  (e)      Parent or the Exchange Agent will be entitled to
deduct and withhold from the Merger Consideration such amounts as Parent or the
Exchange Agent are required to deduct and withhold with respect to the making of
such payment under the Code, or any provision of state, local or foreign tax
law. To the extent that amounts are so withheld, such amounts will be treated
for all purposes of this Agreement as having been paid to the former holder of
the Company Capital Stock in respect of whom such deduction and withholding were
made by Parent or the Exchange Agent.

                  1.8.3    Fractional Shares

                  No Parent Common Stock representing a fraction of Parent
Common Stock or book-entry credit of the same will be issued pursuant to the
Merger, but in lieu thereof each former holder of Company Capital Stock
otherwise entitled to receive a fractional interest in Parent Common Stock will
be entitled to receive in accordance with the provisions of this Section 1.8.3 a
cash payment in lieu of that fractional interest representing the holder's
proportionate interest in the net proceeds from the sale by the Exchange Agent
on behalf of all holders otherwise entitled to fractional interests in shares of
Parent Common Stock (the "EXCESS SHARES"). The sale of the Excess Shares by the
Exchange Agent shall be executed through the Parent's Trading Market. Until the
net proceeds of the sale of the Excess Shares have been distributed to the
former holders of Company Capital Stock, the Exchange Agent will hold the
proceeds in trust for those former holders (the "EXCESS SHARES TRUST").
Commissions, transfer taxes and other out-of-pocket transaction costs, including
the expenses and compensation, of the Exchange Agent incurred in connection with
the sale of the Excess Shares shall be paid from cash held in the Excess Shares
Trust. The Exchange Agent shall determine the portion of the Excess Shares Trust
to which each former holder of Common Stock shall be entitled, if any, by
multiplying the amount of the aggregate net proceeds comprising the Excess
Shares Trust by a fraction the numerator of which shall be the fractional
interest of Parent Common Stock to which such former holder would otherwise be
entitled and the denominator of which is the aggregate amount of fractional
interests in Parent Common Stock to which all former holders of Company Capital
Stock would otherwise be entitled. As soon as practicable after the
determination of the amount of cash, if any, to be paid to former holders of
Company Capital Stock in lieu of fractional interests in Parent Common Stock,
the Exchange Agent shall make available those amounts to the former holders
without interest.

                  1.8.4    No Further Transfers; No Further Ownership Rights In
Company Capital Stock; No Dividends or Other Distributions

         All shares of Parent Common Stock issued upon the surrender for
exchange of shares of Company Capital Stock in accordance with the terms hereof
shall be deemed to have been issued in full satisfaction of all rights
pertaining to such shares of Company Capital Stock, and there shall be no
further registration of transfers on the records of the Surviving Corporation of
shares of Company Capital Stock that were outstanding immediately prior to the
Effective Time. If, after the Effective Time, certificates formerly representing
shares of Company Capital Stock are presented to the Surviving Corporation, they
shall be forwarded to Parent and shall be canceled and exchanged in accordance
with this SECTION 1.8, unless such certificates for Parent Common Stock have
already been issued in respect of such shares in reliance upon an affidavit of
loss or otherwise, in any case subject to applicable law in the case of
Dissenting Shares. No dividends or other distributions payable with respect to
Parent Common Stock shall be paid to the holder of any unsurrendered
certificates evidencing Company Capital Stock until such certificates are
surrendered and exchanged for shares of Parent Common Stock in accordance with
this Agreement.

paid by certified check or wire transfer of funds to a designated account of
Parent, provided that in the event of a wire transfer, wire transfer
instructions are delivered to the Investors at least one business day prior to
the Closing.

                  3.1.5    If prior to the Effective Time, Parent effects a
subdivision of its outstanding shares into a greater number of shares, or a
combination of its outstanding shares into a lesser number of shares, or
reorganizes, reclassifies or otherwise changes its outstanding shares into the

assets, financial condition or results of operations of the Company; provided,
however, that Company Material Adverse Effect shall not include any change,

registration rights granted by the Company with respect to the Company Capital
Stock or Stock Purchase Rights of the Company are described on Schedule 4.3(e)
to the Disclosure Memorandum.

                  (f)      All Options have been granted at the price determined

employees, such agreements are substantially in the Company's standard forms and
also assign to the Company all Intellectual Property Rights relating to the
Company's business that are developed by the employee in the course of his or
her activities for the Company or are developed during working hours using the
resources of the Company. With respect to contractors and consultants, the

of such source code or other Company Intellectual Property from such escrows or
arrangements.

RIGHTS

of the Company entered into in the ordinary course of business (accurate and
complete copies of which have been made available to Parent by the Company), the
Company has not entered into any agreement or offered to indemnify any Person
against any charge of infringement, violation, misappropriation or misuse of
Intellectual Property Rights.

and warrants to Parent as follows:

         5.1      REQUISITE POWER AND AUTHORITY

         Such Investor and Lender has all necessary power and authority under
all applicable provisions of law to execute and deliver this Agreement and to
carry out its provisions. All actions on such Investor's and Lender's part
required for the lawful execution and delivery of this Agreement have been or
will be effectively taken prior to the Closing

         5.2      INVESTMENT REPRESENTATIONS

         Such Investor and Lender understands that neither the H Shares, the
Notes nor the shares of Parent Common Stock into which such H Shares and Notes
are convertible (the "CONVERSION SHARES") have been registered under the
Securities Act of 1933, as amended (the "SECURITIES ACT"). Such Investor and
Lender also understands that the H Shares and Notes, respectively, are being
offered and sold pursuant to an exemption from registration contained in the
Securities Act based in part upon the Investor's representations contained in
this Agreement.

         5.3      INVESTOR BEARS ECONOMIC RISK

         Such Investor and Lender has substantial experience in evaluating and
investing in private placement transactions of securities in companies similar
to Parent so that it is capable of evaluating the merits and risks of its
investment in Parent and has the capacity to protect its own interests. Such
Investor and Lender must bear the economic risk of this investment indefinitely
unless the H Shares or the Notes, respectively (or, in the case of each, the
Conversion Shares) are registered pursuant to the Securities Act, or an
exemption from registration is available. Such Investor and Lender understands
that until the H Shares or the Notes, as the case may be, or the Conversion
Shares are registered, there is no assurance that any exemption from
registration under the Securities Act will be available and that, even if
available, such exemption may not allow such Investor to transfer all or any
portion of the H Shares or Notes, as the case may be, or the Conversion Shares
under the circumstances, in the amounts or at the times such Investor might
propose.

         5.4      ACQUISITION FOR OWN ACCOUNT

         Such Investor and Lender is acquiring the H Shares and Notes,
respectively, and will acquire the Conversion Shares for its own account for
investment only, and not with a view towards their distribution in violation of
applicable securities laws.

management's business or financial experience, such Investor and Lender has the
capacity to protect its own interests in connection with the transactions
contemplated in this Agreement. Further, such Investor and Lender is aware of no
publication of any advertisement in connection with the transactions
contemplated by the Agreement.

         5.6      ACCREDITED INVESTOR

         Such Investor and Lender represents that it is an accredited investor
within the meaning of Regulation D under the Securities Act.

         5.7      PARENT INFORMATION

         Such Investor and Lender has had an opportunity to discuss Parent's
business, management and financial affairs with directors, officers and
management of Parent. Such Investor and Lender has also had the opportunity to
ask questions of, and receive answers from, Parent and its management regarding
the terms and conditions of this investment.

         5.8      RULE 144

         Such Investor and Lender acknowledges and agrees that the H Shares and
Notes, respectively, and the Conversion Shares must be held indefinitely unless
they are subsequently registered under the Securities Act or an exemption from
such registration is available. Such Investor and Lender has been advised or is
aware of the provisions of Rule 144 promulgated under the Securities Act, which
permits limited resale of shares purchased in a private placement subject to the
satisfaction of certain conditions, including, among other things: the
availability of certain current public information about Parent, the resale
occurring not less than one year after a party has purchased and paid for the
security to be sold, the sale being through an unsolicited "broker's
transaction" or in transactions directly with a market maker (as said term is
defined under the Securities Exchange Act of 1934, as amended) and the number of
shares being sold during any three-month period not exceeding specified
limitations.

         5.9      INFORMATION FURNISHED BY INVESTORS AND LENDERS

         Each Investor and each Lender, as to itself or himself only, represents
and warrants the matters set forth in this Section 5.9. None of the information
supplied or to be supplied by the Investor or the Lender in connection with the
transactions contemplated by this Agreement, at the date on which such
information is given or on the Closing Date, contains or will contain any untrue

misleading; provided, however, that the Investor or the Lender

related to any party other than the Investors or the Lenders. None of the

                    6.17.6    NO INFRINGEMENT BY PARENT

         Parent Intellectual Property and the conduct of Parent's business as
currently conducted and as currently proposed to be conducted do not infringe,
violate, misappropriate or otherwise misuse any third party Intellectual
Property Rights, and Parent has not received any complaint, claim or notice
alleging any such infringement, violation, misappropriation or misuse or any act
of unfair competition by Parent. To the best knowledge of Parent, no goods,
services, or other products which are sold, licensed or otherwise supplied, used
or employed by Parent infringe, violate, misappropriate or otherwise misuse any
third party Intellectual Property Rights, and Parent has not received any
complaint, claim or notice alleging any such infringement, violation,
misappropriation or misuse. Nothing has come to the attention of Parent to the
effect that the name of Parent or any business name, trade mark, service mark or
domain name used or owned by Parent is the same as, or is confusingly or
deceptively similar to, the name of any other company or business, trade name or
domain name or to the trade mark or service mark owned or used by any other
person. No litigation is now or, within the five (5) years prior to the date of
this Agreement, was pending and, to the knowledge of Parent, no notice or other
claim in writing has been received by Parent (i) alleging that Parent has
engaged in any activity or conduct that infringes, violates, misappropriates or
otherwise misuses the Intellectual Property Rights of any third party or (ii)
challenging the ownership, use, validity or enforceability of any Parent
Intellectual Property.

                    6.17.7    NO INFRINGEMENT BY THIRD PARTIES

         To Parent's knowledge, no third party is infringing, violating,
misappropriating or misusing any Parent Intellectual Property that is owned or
exclusively licensed to Parent, or committing any act of unfair competition with
respect to Parent, and no such claims have been brought against any third party
by Parent. Parent has not entered into any agreement granting any Person the
right to bring any action with respect to, or otherwise to enforce, any Parent
Intellectual Property.

                    6.17.8    PROTECTION OF INTELLECTUAL PROPERTY RIGHTS

         Parent has taken reasonable steps to protect Parent Intellectual
Property. Without limiting the generality of the foregoing, Parent enforces a
policy of requiring each employee, consultant and contractor of Parent to
execute agreements that contain provisions designed to prevent unauthorized
disclosure of Parent Intellectual Property. With respect to employees, such
agreements are substantially in Parent's standard forms and also assign to
Parent all Intellectual Property Rights relating to Parent's business that are
developed by the employee in the course of his or her activities for Parent or
are developed during working hours using the resources of Parent. With respect
to contractors and consultants, the agreements either assign all Intellectual
Property Rights developed pursuant to the agreement or license such rights on
agreed-upon terms. Except under confidentiality obligations, to the knowledge of
Parent, there has been no


                                       60
<Page>

disclosure by Parent of material confidential information or trade secrets.
Parent has not disclosed any source code to any software to any person or entity
other than an employee of Parent who is under a written nondisclosure agreement;
and, except as described in Schedule 6.17.8, neither Parent nor any escrow agent
is under any contractual or other obligation to disclose any source code or
other Parent Intellectual Property. If, as disclosed on Schedule 6.17.8, Parent
has deposited any source code or other Parent Intellectual Property into source
code escrows or similar arrangements, no event has occurred that has or could
reasonably form the basis for a release of such source code or other Parent
Intellectual Property from such escrows or arrangements.

                    6.17.9    INDEMNIFICATION FOR USE OF INTELLECTUAL PROPERTY
RIGHTS

         Other than pursuant to standard agreements with customers or supppliers
of Parent entered into in the ordinary course of business (accurate and complete
copies of which have been made available to the Company by Parent), Parent has
not entered into any agreement or offered to indemnify any Person against any
charge of infringement, violation, misappropriation or misuse of Intellectual
Property Rights.

                    6.17.10   ASSIGNMENT; CHANGE OF CONTROL

         The execution, delivery and performance by Parent of this Agreement,
and the consummation of the transactions contemplated hereby, will not result in
the loss or impairment of, or give rise to any right of any third party to
terminate or alter, any of the Parent Intellectual Property or Parent's rights
under any Parent Inbound License Agreement or Parent Outbound License Agreement,
nor require any consent in respect of any Parent Intellectual Property, nor
require any disclosure or release of any source code or other Parent
Intellectual Property from any escrows or other arrangements.

         6.18     ACCOUNTS RECEIVABLE

         All accounts receivable of Parent reflected in the Parent Balance Sheet

sets forth the value of all raw materials and work in progress as of July 31,

reflect in all material respects the events of and actions taken at such
meetings.

         6.21     LICENSES, PERMITS, AUTHORIZATIONS, ETC.

         Parent has received all required Permits, except where the failure to

expiration dates, if any. Parent is in material compliance with the terms of all
Permits, and all Permits are valid and in full force and effect, and no
proceeding is pending or, to Parent's knowledge, threatened, the object of which
is to revoke, limit or otherwise affect any Permit. Parent has not received any
notifications of any asserted failure to obtain any Permit or any past and
unremedied failure to obtain any Permit.

         6.22     COMPLIANCE WITH LAWS

commissions or any similar charges in connection with the Merger, this Agreement
or any transactions contemplated hereby.

         10.12    NO SOLICITATION, ETC.

                  (a) Each of the Company and Parent (the "Agreeing Party")
agrees that it shall not, nor shall it permit any of its subsidiaries to, nor
shall it authorize any officer, director or employee or any investment banker,
attorney, accountant, agent or other advisor or representative or any of its
subsidiaries to (i) solicit, initiate or knowingly encourage the submission of
any Takeover Proposal (as hereinafter defined), (ii) enter into any agreement
with respect to a Takeover Proposal or (iii) participate in any discussions or
negotiations regarding, or furnish to any person any information with respect
to, any inquiries or the making of any proposal that constitutes, or may
reasonably be expected to lead to, any Takeover Proposal; PROVIDED, HOWEVER,
that to the extent required by the fiduciary obligations of the Board of
Directors of the Agreeing Party, as determined in good faith by a majority of
the members thereof (after consultation with outside legal counsel), the
Agreeing Party may, in response to unsolicited requests therefor, participate in
discussions or negotiations with, or furnish information pursuant to a
confidentiality agreement no less favorable to such party in all material
respects than the Confidentiality Agreement to, any person who indicates a
willingness to make a Superior Proposal (as hereinafter defined). For all
purposes of this Agreement, "TAKEOVER PROPOSAL" means any proposal for a merger,
consolidation, share exchange, business combination or other similar transaction
involving the Agreeing Party or any of its Significant Subsidiaries (as
hereinafter defined), or any proposal or offer to acquire, directly or
indirectly, 25% or more of any class of equity securities in, 25% or more of any
voting securities of, or 25% or more of the assets of, the Agreeing Party or any
of its Significant Subsidiaries, as the case may be. The Agreeing Party shall

any persons conducted heretofore with respect to, or that could reasonably be
expected to lead to, any Takeover Proposal. As used herein, a "SIGNIFICANT
SUBSIDIARY" means any subsidiary of the Agreeing Party that would constitute a
"SIGNIFICANT SUBSIDIARY" within the meaning of Rule 1-02 of Regulation S-X of
the SEC.

                  (b) Except to the extent permitted below, neither the Board of
Directors of the Agreeing Party nor any committee thereof shall (i) withdraw or
modify, in a manner adverse to the other party (either the Company or Parent),
the approval or recommendation by the Board of Directors of the Agreeing Party
or any such committee


                                       83
<Page>

of this Agreement or the Merger or (ii) approve or recommend, or propose to
approve or recommend, any Takeover Proposal. Notwithstanding the foregoing, (i)
the Board of Directors of the Agreeing Party, to the extent required by its
fiduciary obligations and subject to Section 11.2 hereof, as determined in good
faith by a majority of the members thereof (after consultation with outside
legal counsel), may approve or recommend a Superior Proposal (and, in connection
therewith, withdraw or modify its approval or recommendation of this Agreement
or the Merger) and (ii) nothing contained in this Agreement shall prevent the
Board of Directors of the Agreeing Party from complying with Rule 14d-9 and Rule
14e-2 promulgated under the Exchange Act with regard to a Takeover Proposal, if
applicable. For all purposes of this Agreement, "SUPERIOR PROPOSAL" means a bona
fide written proposal made by a third party to acquire the Agreeing Party
pursuant to a tender or exchange offer, a merger or other business combination,
a share exchange, a sale of all or substantially all its assets or otherwise on

Party determines in good faith (taking into account the advice of any
independent financial advisors) to be more favorable to the Agreeing Party and
its stockholders than the Merger (and any revised proposal made by the other
party) and for which financing, to the extent required, is then fully committed
or reasonably determined to be likely to be available by the Board of Directors
of the Agreeing Party.

                  (c) The Agreeing Party shall notify the other party (either
the Company or Parent) promptly (but in no event later than the next business
day) after receipt by the Agreeing Party (or its advisors) of any Takeover
Proposal or any request for nonpublic information in connection with a Takeover
Proposal or for access to the properties, books or records of the Company by any
person or entity that informs the Company or its advisors that it is considering
making, or has made, a Takeover Proposal. Such notice shall indicate the
identity of the person making the Takeover Proposal, inquiry or contact, and the
material terms and conditions of the Takeover Proposal, inquiry or contact and
shall include copies of any written materials received by the Agreeing Party or
its representatives in connection with such proposal, discussion, negotiation or
inquiry.

         10.13    REGULATORY AND OTHER APPROVALS.

                  10.13.1 Subject to the terms and conditions of this Agreement
and the other Operative Documents, each of the Company and Parent will use
commercially reasonable efforts to do, or cause to be done, all things
necessary, proper or advisable to, as promptly as practicable, obtain all
consents, approvals or actions of, make all filings with and give all notices to
any court, tribunal or administrative, governmental or regulatory body, agency,
commission, division, department, public body or other authority, whether
federal, state, local or foreign (each a "GOVERNMENTAL ENTITY") or any other
public or private third parties required of the Company, Parent or the Merger
Sub to consummate the Merger and provide such other information and
communications to such Governmental Entities or other public or private third
parties as the other party hereto or such Governmental Entities or other public
or private third parties may


                                       84
<Page>

reasonably request. In addition to and not in limitation of the foregoing, each
of the parties will (x) take promptly all actions necessary to make the filings
required of Parent and the Company or their affiliates under the
Hart-Scott-Rodino Act and under comparable merger notification or competition
laws of non-U.S. jurisdictions, (y) comply at the earliest practicable date with
any request for additional information received by such party or its affiliates
from the Federal Trade Commission (the "FTC") or the Antitrust Division of the
Department of Justice (the "Antitrust Division") pursuant to the
Hart-Scott-Rodino Act or the authorities of such other jurisdictions, and (z)
cooperate with the other party in connection with such party's filings under the
Hart-Scott-Rodino Act and in connection with resolving any investigation or
other inquiry concerning the Merger or the other matters contemplated by this
Agreement commenced by the FTC, the Antitrust Division, state attorneys general
or any other Governmental Entity.

                  10.13.2 In furtherance and not in limitation of the covenants
in Section 10.5, Parent and the Company shall each use all reasonable efforts to
resolve such objections, if any, as may be asserted with respect to any
transactions contemplated by this Agreement by any Governmental Entity. If any
administrative, judicial or legislative action or proceeding is threatened to be
instituted by any such authority challenging any of the transactions
contemplated by this Agreement, Parent and the Company will each cooperate to
contest and resist the institution of any such action or proceeding.

         10.14    COMPANY EMPLOYEES

                  10.14.1 From and after the Effective Time, Parent and the
Surviving Corporation will honor and assume (and Parent guarantees the
obligations of Surviving Corporation hereunder), in accordance with their terms,
all indemnification obligations of the Company under the Company's Certificate
of Incorporation and Bylaws, each as in effect as of the date of this Agreement
to any officer, director, agent or employee of the Company for acts and
omissions prior to the Closing. Parent shall cause all employees of the
Surviving Corporation immediately after the Effective Time to be eligible to
participate in the "employee welfare benefit plans" and "employee pension plans"
(within the meaning of Section 3(1) and Section 3(2) of ERISA, respectively) of
Parent in which similarly situated employees of Parent are generally eligible to
participate (or, alternatively, may choose in their discretion to continue
certain or all of the benefit plans currently provided by Company to its
employees or otherwise to provide benefits comparable to some or all of such
plans); provided that nothing herein shall prevent Merger Sub or Parent from
terminating the employment of any such employee or modifying or terminating such
plans from time to time. For purposes of any length of service requirements,
waiting periods, vesting periods or differential benefits based on length of
service in any such plan for which an employee may be eligible after the
Effective Time, Merger Sub or Parent shall ensure that service by such employee
with the Company shall be deemed to have been service with Merger Sub or Parent,
as applicable, including with respect to existing options held by employees of
the Company: provided that options granted by Parent to employees of the
Surviving Corporation

                                       85

<Page>

immediately following the Effective Time to effect the intent of this
paragraph shall be vested no more than to the same extent that they would
have been vested had they been granted pursuant to the customary terms of
Parent's stock option grants (which currently vest in equal monthly
increments over a four year period) and had such employee been hired upon the
later of (i) two years prior to such date of grant or (ii) the date that such
employee commenced full-time employment at the Company as though such grant
had been made on such deemed date of hire, and in no event shall such options
be vested on the date of grant by Parent as to more than 50% of the shares
subject to such option and the Company and Parent agree to cooperate
reasonably to implement this provision on a case by case basis.

                  10.14.2 Parent confirms that it is Parent's intention that,
subject to applicable law, Parent and the Surviving Corporation will provide
salary and benefits to employees of the Company who continue to be employed by
the Surviving Corporation after the Effective Time, including participation in
the stock option and other compensatory plans of Parent, which will, in the
aggregate, be substantially equivalent, to those currently provided by Parent
to its similarly situated employees. Notwithstanding the foregoing, nothing in
this Agreement shall otherwise limit the Surviving Corporation's right to
amend, modify or terminate any employee benefit plan or arrangement. Parent
agrees that any person employed by the Company at the Effective Time whose
employment is terminated by the Surviving Corporation on or prior to the first
anniversary of the Effective Time shall be provided severance benefits pursuant
to any written severance agreement, substantially as described on the Company's
Disclosure Memorandum or substantially similar to that provided to similarly
situated employees of Parent at the time of termination.

         10.15    RIGHTS AGREEMENT.

         Parent will not take any action to revoke, amend or nullify the
amendment to the Rights Agreement referred to in Section 6.5(b), (the "Rights
Amendment"); provided, however that Parent may amend the Rights Amendment (i)
solely for the purpose of including in the definition of "Acquiring Person"
Meritage and its Affiliates and Associates in the event that they
beneficially hold 20% or more of the Common Shares then outstanding and (ii)
with the prior written consent of Meritage.

                                   ARTICLE XI
                        TERMINATION, AMENDMENT AND WAIVER

         11.1     TERMINATION

         This Agreement may be terminated and the Merger may be abandoned at any
time prior to the Effective Time (notwithstanding any approval of this Agreement
by the stockholders of the Company):

                  (a) by mutual written consent of the Company and Parent;

                  (b) by either the Company or Parent, if the Merger has not
been consummated by December 31, 2001; provided, however, that (x) the right to
terminate this Agreement under this subsection (b) shall not be available to any
party whose failure to fulfill any obligation under this Agreement has been the
cause of, or resulted in, the failure of the Effective Time to occur on or
before such date and (y) such date shall be extended by one day for each day
following 14 days after the execution of this Agreement that the Company has not
provided to Parent the information referred to in


                                       86
<Page>

the last sentence of Section 10.6.2 in the form for inclusion in the
Proxy/Registration Statement;

                  (c) by either the Company or Parent, if there shall be any law
or regulation that makes consummation of the Merger illegal or if any judgment,
injunction, order or decree enjoining Parent, Merger Sub or the Company from
consummating the Merger is entered and such judgment, injunction, order or
decree shall become final, binding and nonappealable; provided, however, that
the party seeking to terminate this Agreement pursuant to this subsection (c)
shall have used all reasonable efforts to remove such judgment, injunction,
order or decree;

                  (d) by the Company, in the event of a breach by Parent of any
representation, warranty or agreement contained herein that has not been cured,
or as to which best efforts are not being employed to cure within 30 days after
notice thereof is given to Parent and such breach has resulted in a Parent
Material Adverse Effect or if the conditions to the Company's obligations in
Article VIII become incapable of satisfaction through no fault of the Company;

                  (e) by Parent, in the event of a breach by the Company of any
representation, warranty or agreement contained herein that has not been cured
or as to which best efforts are not being employed to cure within 30 days after
notice thereof is given to the Company and such breach has resulted in a Company
Material Adverse Effect or if the conditions to Parent's obligations in Article
VII become incapable of satisfaction through no fault of Parent;

                  (f) by Parent or the Company in connection with entering into
a definitive agreement permitted by Section 10.12; provided that the terminating
party has complied with all provisions thereof, including the notice provisions
therein and the payment of amounts pursuant to Section 11.2;

                  (g) by Parent if the votes required by the holders of the
Company Capital Stock in order to approve the Merger and the transactions
contemplated by this Agreement and the other Operative Documents are not
received on or before the Closing Date by written consent or at a duly held
meeting of the holders of the Company Capital Stock after such a meeting has
been held; or

                  (h) by the Company if the votes required by the holders of the
Parent Capital Stock in order to approve the Merger and the transactions
contemplated by this Agreement and the other Operative Documents are not
received on or before the Closing Date at a duly held meeting of the holders of
the Parent Capital Stock after such a meeting has been held.

         11.2     EFFECT OF TERMINATION.

                  11.2.1 In the event of termination of this Agreement by either
the Company or Parent as provided in Section 11.1, written notice thereof shall
be given as


                                       87
<Page>

promptly as possible to the other party hereto, and this Agreement shall
forthwith become null and void and there shall be no liability or obligation on
the part of either the Company or Parent (or any of their respective
Representatives or affiliates), except (i) that the provisions of Sections 10.3
and 10.5, this Section 11.2 and Article XII will continue to apply following any
such termination, (ii) that nothing contained herein shall relieve any party
hereto from liability for breach of its representations, warranties, covenants
or agreements contained in this Agreement, and (iii) as provided in Section
11.2.2 below.

                  11.2.2 If either party terminates this Agreement pursuant to
Section 11.1(f), the terminating party shall pay to the non-terminating party by
wire transfer in immediately available funds to an account specified in writing
by the non-terminating party immediately upon notice of such termination, a
termination fee of One Million US Dollars (US$1,000,000) and, if the Parent is
the non-terminating party, the Parent shall immediately repay the Notes in full
in accordance with their terms.

                  11.2.3 The parties acknowledge that the agreements in Section
11.2.2 are an integral part of the transactions contemplated by this Agreement,
and that, without these agreements, they each would not enter into this
Agreement; accordingly, if either party fails to pay in a timely manner the
amounts due pursuant to Section 11.2.2 and, in order to obtain such payment, the
non-terminating party makes a claim that results in a judgment against the other
party for the amounts set forth in Section 11.2.2, the terminating party shall
pay to the non- terminating party its reasonable costs and expenses (including
reasonable attorneys' fees and expenses) in connection with such suit, together
with interest on the amounts set forth in Section 11.2.2 from the date of demand
to the date of payment at the rate published as the "prime rate" daily in THE
WALL STREET JOURNAL in effect on the date such payment was required to be made.

                  11.2.4 If any provision of this Section 11.2 shall be void
under applicable law, or if the performance by any party of its obligations
hereunder is prohibited by applicable law, but such provision or action would be
permissible if some part or all of Section 11.2 were deleted, then such
modification as may be necessary to make such provision or action permissible
shall be deemed to have taken place.

         11.3     AMENDMENT

         This Agreement may be amended by the parties hereto at any time before
or after approval of Parent's or Company's stockholders; after such approval,
however, no amendment will be made that by applicable law requires the further
approval of Parent's or Company's stockholders without obtaining such further
approval.

         11.4     WAIVER

         At any time prior to the Effective Time, any party hereto may (a)
extend the time for the performance of any obligation or other act of any other
party hereto, (b) waive any inaccuracy in the representations and warranties
contained herein or in any


                                       88
<Page>

document delivered pursuant hereto, or (c) waive compliance with any agreement
or condition contained herein. Any such extension or waiver shall be valid only
if set forth in an instrument in writing signed by the party or parties to be
bound thereby.

                                  ARTICLE XII
                                     GENERAL

         12.1     NO SURVIVAL OF REPRESENTATIONS AND WARRANTIES

                  None of the representations and warranties in this Agreement
or in any instrument or document delivered pursuant to this Agreement shall
survive the Effective Time. THIS SECTION 12.1 shall not limit any covenant or
agreement of the parties which by its terms contemplates performance after the
Effective Time.

         12.2     EXPENSES

         Regardless of whether the transactions contemplated by this Agreement
are consummated, each party shall pay its own fees and expenses incident to the
negotiation, preparation and execution of this Agreement and the other Operative
Documents (including investment banking, legal and accounting fees and
expenses),

         12.3     NOTICES

         Any notice, request or demand desired or required to be given hereunder
shall be in writing given by personal delivery, confirmed facsimile transmission
or overnight courier service, in each case addressed as respectively set forth
below or to such other address as any party shall have previously designated by
such a notice. The effective date of any notice, request or demand shall be the
date of personal delivery, the date on which successful facsimile transmission
is confirmed or the date actually delivered by a reputable overnight courier
service, as the case may be, in each case properly addressed as provided herein
and with all charges prepaid.

         12.4     SEVERABILITY

         If any term or other provision of this Agreement is invalid, illegal or
incapable of being enforced by any rule of law, or public policy, all other
conditions and provisions of this Agreement shall nevertheless remain in full
force and effect so long as the economic or legal substance of the transactions
contemplated hereby is not affected in any manner adverse to any party. Upon
such determination that any term or other provision is invalid, illegal or
incapable of being enforced, the parties hereto shall negotiate in good faith to
modify this Agreement so as to effect the original intent of the parties as

respect to the subject matter hereof and thereof.

         12.6     ASSIGNMENT

         This Agreement shall not be assigned by operation of law or otherwise;
provided, however, that Merger Sub's rights and obligations may be assigned to
and assumed by Parent or any other corporation wholly owned (directly or through
intermediate wholly owned subsidiaries) by Parent, provided that in such event
Parent shall unconditionally guarantee the full payment and performance of all
obligations of such assignee.

         12.7     PARTIES IN INTEREST

         This Agreement shall be binding on and inure solely to the benefit of

court located in the State of Colorado or any federal or state court located in
the State of Delaware. Each of the parties hereto (a) consents to submit itself

or the State of Delaware, as the case may be, in the event any dispute arises
out of or relates to this Agreement or any of the transactions contemplated by
this Agreement, (b) agrees that it will not attempt to deny or defeat such
personal jurisdiction by motion or other request for leave from any such court,
including, without limitation, a motion to dismiss on the grounds of forum non
conveniens, (c) agrees that it will not bring any action arising out of or
relating to this Agreement or any of the transactions contemplated by this
Agreement in any court other than a federal court sitting in the State of
Delaware or the State of Colorado or a Delaware state court, (d) agrees that a
final judgment in any such action or proceeding shall be conclusive and may be
enforced in other jurisdictions by suit on the judgment or in any other manner
specified by law, and (e) waives any right to a trial by jury with respect to

         The terms and provisions of this Agreement are intended solely for the
benefit of each party hereto and their respective successors or permitted
assigns, and, except as provided in Sections 10.14.1 and 10.14.2, it is not the
intention of the parties to confer third-party beneficiary rights under any
other person.

         This Agreement may be executed and delivered (including by facsimile
transmission) in one or more counterparts, and by the different parties hereto
in separate counterparts, each of which when executed and delivered shall be
deemed to be an original but all of which taken together shall constitute one
