                  MASTER SEPARATION AND DISTRIBUTION AGREEMENT

         This Master Separation and Distribution Agreement (this "AGREEMENT") is
entered into as of September 21, 2000, between Adaptec, Inc. ("ADAPTEC"), a
Delaware corporation, and Roxio, Inc. ("ROXIO"), a Delaware corporation.
Capitalized terms used herein and not otherwise defined shall have the meanings
ascribed to such terms in ARTICLE VII hereof. Adaptec and Roxio are sometimes
referred to herein individually as a "party" or collectively as the "parties."

                                    RECITALS

         WHEREAS, the Boards of Directors of each of Adaptec and Roxio have
determined that it is appropriate and desirable for Adaptec to contribute and
transfer to Roxio, and for Roxio to receive and assume, directly or indirectly,
substantially all of the assets and liabilities currently associated with the
Roxio Business and the stock, investments or similar interests currently held by
Adaptec in subsidiaries and other entities that conduct such business (the
"SEPARATION");

         WHEREAS, Adaptec has caused Roxio to be incorporated in order to effect
the Separation and Adaptec currently owns all of the issued and outstanding
capital stock of Roxio;

         WHEREAS, Adaptec and Roxio currently contemplate that, following the
contribution and assumption of assets and liabilities, Roxio will make an
initial public offering ("IPO") of an amount of its common stock pursuant to a
registration statement on Form S-1 pursuant to the Securities Act of 1933, as
amended (the "IPO REGISTRATION STATEMENT"), that will reduce Adaptec's ownership
of the issued and outstanding capital stock of Roxio to not less than 80.1%;

         WHEREAS, Adaptec currently contemplates that, several months following
the IPO, Adaptec will distribute to the holders of its common stock, $ 0.01 par
value, by means of a pro rata distribution, all of the shares of Roxio common
stock owned by Adaptec (the "DISTRIBUTION");

         WHEREAS, Adaptec and Roxio intend that the Separation and the
Distribution will qualify as a tax-free reorganization under Sections
368(a)(1)(D) and 355 of the Internal Revenue Code of 1986, as amended (the
"CODE"), and that this Agreement is intended to be, and is hereby adopted as, a
plan of reorganization under Section 368 of the Code; and

         WHEREAS, the parties intend in this Agreement, including the Exhibits
and Schedules hereto, to set forth the principal arrangements between them
regarding the separation of the Roxio Business.

         NOW, THEREFORE, in consideration of the foregoing and the covenants and
agreements set forth below, the parties hereto agree as follows:

qualify under Sections 355 and 368 of the Code as tax-free to Adaptec, Roxio and
Adaptec's stockholders shall, to the extent applicable as of the time of the
IPO, be satisfied. There shall be no event or condition that is likely to cause
any of such conditions not to be satisfied as of the time of the Distribution or
thereafter.

          (e) NO LEGAL RESTRAINTS. No order, injunction or decree issued by any

the other transactions contemplated by this Agreement shall be in effect.

          (f) SEPARATION. The Separation shall have become effective as

     SECTION 4.1 THE DISTRIBUTION.

          (a) DELIVERY OF SHARES FOR DISTRIBUTION. Subject to SECTION 4.4
hereof, on or prior to the date the Distribution is effective (the "DISTRIBUTION
DATE"), Adaptec will deliver to the distribution agent (the "DISTRIBUTION
AGENT") to be appointed by Adaptec to distribute to the stockholders of Adaptec
the shares of common stock of Roxio held by Adaptec pursuant to the Distribution
for the benefit of holders of record of common stock of Adaptec on the Record
Date, a single stock certificate, endorsed by Adaptec in blank, representing all
of the outstanding shares of common stock of Roxio then owned by Adaptec, and
shall cause the transfer agent for the shares of common stock of Adaptec to
instruct the Distribution Agent to distribute on the Distribution Date the
appropriate number of such shares of common stock of Roxio to each such holder
or designated transferee or transferees of such holder.

          (b) SHARES RECEIVED. Subject to SECTIONS 4.4 and 4.5, each holder of
common stock of Adaptec on the Record Date (or such holder's designated
transferee or transferees) will be entitled to receive in the Distribution a
number of shares of common stock of Roxio equal to the number of shares of
common stock of Adaptec held by such holder on the Record Date multiplied by a
fraction the numerator of which is the number of shares of common stock of Roxio
beneficially owned by Adaptec on the Record Date and the denominator of which is
the number of shares of common stock of Adaptec outstanding on the Record Date.

          (c) OBLIGATION TO PROVIDE INFORMATION. Roxio and Adaptec, as the case
may be, will provide to the Distribution Agent all share certificates and any
information required in order to complete the Distribution on the basis
specified above.

     SECTION 4.2 ACTIONS PRIOR TO THE DISTRIBUTION.

          (a) INFORMATION STATEMENT. Adaptec and Roxio shall prepare and mail,
prior to the Distribution Date, to the holders of common stock of Adaptec, such
information concerning Roxio and the Distribution and such other matters as
Adaptec and Roxio shall reasonably determine are necessary and as may be
required by law. Adaptec and Roxio will prepare, and Roxio will, to the extent
required under applicable law, file with the Commission any such documentation
which Adaptec and Roxio reasonably determine is necessary or desirable to
effectuate the Distribution, and Adaptec and Roxio shall each use its reasonable
commercial efforts to obtain all necessary approvals from the Commission with
respect thereto as soon as practicable.

          (b) BLUE SKY. Adaptec and Roxio shall take all such actions as may be
necessary or appropriate under the securities or blue sky laws of the United

          (c) NASDAQ LISTING. Roxio shall prepare and file, and shall use its
reasonable commercial efforts to have approved, an application for the listing
of the common stock of Roxio to be distributed in the Distribution on Nasdaq,
subject to official notice of distribution.

necessary and appropriate to cause the conditions set forth in SECTION 4.4 to be
satisfied and to effect the Distribution on the Distribution Date.

     SECTION 4.3 SOLE DISCRETION OF ADAPTEC. Adaptec currently intends,
following the consummation of the IPO, to complete the Distribution by June 30,
2001. Adaptec shall, in its sole and absolute discretion, determine the date of
the consummation of the Distribution and all terms of the Distribution,
including, without limitation, the form, structure and terms of any
transaction(s) and/or offering(s) to effect the Distribution and the timing of
and conditions to the consummation of the Distribution. In addition, Adaptec may
at any time and from time to time until the completion of the Distribution
modify or change the terms of the Distribution, including, without limitation,
by accelerating or delaying the timing of the consummation of all or part of the
Distribution. Roxio shall cooperate with Adaptec in all respects to accomplish
the Distribution and shall, at Adaptec's direction, promptly take any and all
actions necessary or desirable to effect the Distribution, including, without
limitation, the registration under the Securities Act of the common stock of
Roxio on an appropriate registration form or forms to be designated by Adaptec.
Adaptec shall select any investment banker(s) and manager(s) in connection with
the Distribution, as well as any financial printer, solicitation and/or exchange
agent and outside counsel for Adaptec; PROVIDED, HOWEVER, that nothing herein
shall prohibit Roxio from engaging (at its own expense) its own financial,
legal, accounting and other advisors in connection with the Distribution.

     SECTION 4.4 CONDITIONS TO DISTRIBUTION. The following are conditions to the
consummation of the Distribution. The conditions are for the sole benefit of
Adaptec and shall not give rise to or create any duty on the part of Adaptec or
the Adaptec Board of Directors to waive or not waive any such condition.

          (a) IRS RULING. Adaptec shall have obtained a private letter ruling
from the Internal Revenue Service in form and substance satisfactory to Adaptec
(in its sole discretion), and such ruling shall remain in effect as of the
Distribution Date, to the effect that (i) the transfer by the Adaptec Group to
the Roxio Group of the property, subject to liabilities, of the Roxio Business
in exchange for the issuance to Adaptec of the stock of Roxio, and Roxio's
assumption of liabilities, followed by the distribution by Adaptec of all of its
Roxio stock to the stockholders of Adaptec, will qualify as a reorganization
under Sections 368(a)(1)(D) and 355 of the Code; (ii) no gain or loss will be
recognized by Adaptec on its transfer of the property of the Roxio Business to
Roxio in exchange for Roxio common stock; (iii) no gain or loss will be
recognized by Roxio on its receipt of the property of the Roxio Business from
Adaptec in exchange for the issuance of Roxio common stock; and (iv) no gain or
loss will be recognized by (and no amount will otherwise be included in the
income of) the stockholders of Adaptec upon their receipt of Roxio common stock
pursuant to the Distribution.

          (b) GOVERNMENT APPROVALS. Any material governmental approvals and
consents necessary to consummate the Distribution shall have been obtained and
be in full force and effect;


                                      -7-
<PAGE>

          (c) NO LEGAL RESTRAINTS. No order, injunction or decree issued by any
court or agency of competent jurisdiction or other legal restraint or
prohibition preventing the consummation of the Distribution shall be in effect
and no other event outside the control of Adaptec shall have occurred or failed
to occur that prevents the consummation of the Distribution; and

          (d) NO MATERIAL ADVERSE EFFECT. No other events or developments shall
have occurred subsequent to the IPO Closing Date that, in the judgment of the
Board of Directors of Adaptec, would result in the Distribution having a
material adverse effect on Adaptec or on the stockholders of Adaptec.

     SECTION 4.5 FRACTIONAL SHARES. As soon as practicable after the
Distribution Date, Adaptec shall direct the Distribution Agent to determine the
number of whole shares and fractional shares of common stock of Roxio allocable
to each holder of record or beneficial owner of common stock of Adaptec as of
the Record Date, to aggregate all such fractional shares and sell the whole
shares obtained thereby at the direction of Adaptec, in open market
transactions, at then prevailing trading prices, and to cause to be distributed
to each such holder or for the benefit of each such beneficial owner to which a
fractional share shall be allocable such holder's or owner's ratable share of
the proceeds of such sale, after making appropriate deductions of the amount
required to be withheld for federal income tax purposes and after deducting an
amount equal to all brokerage charges, commissions and transfer taxes attributed
to such sale. Adaptec and the Distribution Agent shall use their reasonable
commercial efforts to aggregate the shares of common stock of Adaptec that may
be held by any beneficial owner thereof through more than one account in
determining the fractional share allocable to such beneficial owner.

                                   ARTICLE V

                           COVENANTS AND OTHER MATTERS

     SECTION 5.1 OTHER AGREEMENTS. In addition to the specific agreements,
documents and instruments that are Exhibits to this Agreement, Adaptec and Roxio
agree to execute or cause to be executed by the appropriate parties and deliver,
as appropriate, such other agreements, instruments and other documents as may be
necessary or desirable in order to effect the purposes of this Agreement and the
Ancillary Agreements.

     SECTION 5.2 FURTHER INSTRUMENTS. At the request of Roxio and without
further consideration, Adaptec will execute and deliver, and will cause its
applicable Subsidiaries to execute and deliver, to Roxio and its Subsidiaries
such other instruments of transfer, conveyance, assignment, substitution and
confirmation and take such action as Roxio may reasonably deem necessary or
desirable in order more effectively to transfer, convey and assign to Roxio and
its Subsidiaries and confirm Roxio's and its Subsidiaries' title to all of the
assets, rights and other things of value contemplated to be transferred to Roxio
and its Subsidiaries pursuant to this Agreement, the Ancillary Agreements, and
any documents referred to therein, to put Roxio and its Subsidiaries in actual
possession and operating control thereof and to permit Roxio and its
Subsidiaries to exercise all rights with respect thereto (including, without
limitation, rights under contracts and other arrangements as to which the
consent of any third party to the transfer thereof shall not have


                                      -8-
<PAGE>

previously been obtained). At the request of Adaptec and without further
consideration, Roxio will execute and deliver, and will cause its applicable
Subsidiaries to execute and deliver, to Adaptec and its Subsidiaries all
instruments, assumptions, novations, undertakings, substitutions or other
documents and take such other action as Adaptec may reasonably deem necessary or
desirable in order to have Roxio fully and unconditionally assume and discharge
the liabilities contemplated to be assumed by Roxio under this Agreement or any
document in connection herewith and to relieve the Adaptec Group of any
liability or obligation with respect thereto and evidence the same to third
parties. Neither Adaptec nor Roxio shall be obligated, in connection with the
foregoing, to expend money other than reasonable out-of-pocket expenses,
attorneys' fees and recording or similar fees. Furthermore, each party, at the
request of another party hereto, shall execute and deliver such other
instruments and do and perform such other acts and things as may be necessary or
desirable for effecting completely the consummation of the transactions
contemplated hereby.

     SECTION 5.3 AGREEMENT FOR EXCHANGE OF INFORMATION. Each of Adaptec and
Roxio agrees to provide, or cause to be provided, to each other, at any time
before or after the Distribution Date, as soon as reasonably practicable after
written request therefor, any Information in the possession or under the control
of such party that the requesting party reasonably needs (i) to comply with
reporting, disclosure, filing or other requirements imposed on the requesting
party (including under applicable securities laws) by a Governmental Authority
having jurisdiction over the requesting party, (ii) for use in any other
judicial, regulatory, administrative or other proceeding or in order to satisfy
audit, accounting, claims, regulatory, litigation or other similar requirements,
(iii) to comply with its obligations under this Agreement or any Ancillary
Agreement or (iv) in connection with the ongoing businesses of Adaptec or Roxio,
as the case may be; PROVIDED, HOWEVER, that in the event that any party
determines that any such provision of Information could be commercially
detrimental, violate any law or agreement, or waive any attorney-client
privilege, the parties shall take all reasonable measures to permit the
compliance with such obligations in a manner that avoids any such harm or
consequence.

          (a) INTERNAL ACCOUNTING CONTROLS; FINANCIAL INFORMATION. Until the
seventh anniversary of the Separation Date, (i) each party shall maintain in
effect at its own cost and expense adequate systems and controls for its
business to the extent necessary to enable the other party to satisfy its
reporting, accounting, audit and other obligations, and (ii) each party shall
provide, or cause to be provided, to the other party and its Subsidiaries in
such form as such requesting party shall request, at no charge to the requesting
party, all financial and other data and information as the requesting party
determines necessary or advisable in order to prepare its financial statements
and reports or filings with any Governmental Authority.

          (b) OWNERSHIP OF INFORMATION. Any Information owned by a party that is
provided to a requesting party pursuant to this SECTION 5.3 shall be deemed to
remain the property of the providing party. Unless specifically set forth
herein, nothing contained in this Agreement shall be construed as granting or
conferring rights of license or otherwise in any such Information.

          (c) RECORD RETENTION. To facilitate the possible exchange of
Information pursuant to this SECTION 5.3 and other provisions of this Agreement
after the Distribution Date, each party agrees to use its reasonable commercial
efforts to retain all tax, employee and financial Information in their
respective possession or control on the Distribution Date for seven years after
the Distribution Date.


                                      -9-
<PAGE>

No party will destroy, or permit any of its Subsidiaries to destroy, any
Information that exists on the Separation Date (other than Information that is
permitted to be destroyed under the current record retention policy of such
party) without first using its reasonable commercial efforts to notify the other
party of the proposed destruction and giving the other party the opportunity to
take possession of such Information prior to such destruction.

          (d) LIMITATION OF LIABILITY. No party shall have any liability to any
other party in the event that any Information exchanged or provided pursuant to
this SECTION 5.3 is found to be inaccurate, in the absence of willful misconduct
by the party providing such Information. No party shall have any liability to
any other party if any Information is destroyed or lost after reasonable
commercial efforts by such party to comply with the provisions of SECTION
5.3(c).

          (e) OTHER AGREEMENTS PROVIDING FOR EXCHANGE OF INFORMATION. The rights
and obligations granted under this SECTION 5.3 are subject to any specific
limitations, qualifications or additional provisions on the sharing, exchange or
confidential treatment of Information set forth in this Agreement and any
Ancillary Agreement.

          (f) PRODUCTION OF WITNESSES; RECORDS; COOPERATION. After the
Distribution Date, except in the case of a legal or other proceeding by one
party against another party (which shall be governed by such discovery rules as
may be applicable under SECTION 5.7 or otherwise), each party hereto shall use
its reasonable commercial efforts to make available to each other party, upon
written request, the former, current and future directors, officers, employees,
other personnel and agents of such party as witnesses and any books, records or
other documents within its control or which it otherwise has the ability to make
available, to the extent that any such person (giving consideration to business
demands of such directors, officers, employees, other personnel and agents) or
books, records or other documents may reasonably be required in connection with
any legal, administrative or other proceeding in which the requesting party may
from time to time be involved, regardless of whether such legal, administrative
or other proceeding is a matter with respect to which indemnification may be
sought hereunder. The requesting party shall bear all costs and expenses in
connection therewith.

     SECTION 5.4 AUDITORS AND AUDITS; ANNUAL AND QUARTERLY STATEMENTS AND
ACCOUNTING. Each party agrees that, for so long as Adaptec is required in
accordance with GAAP to consolidate Roxio's results of operations and financial
position in Adaptec's financial statements:

          (a) SELECTION OF AUDITORS. Roxio shall not select a different
accounting firm than PricewaterhouseCoopers, LLP to serve as its (and its
Subsidiaries') independent certified public accountants ("ROXIO'S AUDITORS") for
purposes of providing an opinion on its consolidated financial statements
without Adaptec's prior written consent (which shall not be unreasonably
withheld).

          (b) DATE OF AUDITORS' OPINION AND QUARTERLY REVIEWS. Roxio shall use
its reasonable commercial efforts to enable the Roxio Auditors to complete their
audit such that they will date their opinion on Roxio's audited annual financial
statements on the same date that Adaptec's independent certified public
accountants ("ADAPTEC'S AUDITORS") date their opinion on Adaptec's audited
annual financial statements, and to enable Adaptec to meet its timetable for the
printing, filing and public dissemination of Adaptec's annual financial
statements. Roxio shall use its reasonable commercial


                                      -10-
<PAGE>

efforts to enable the Roxio Auditors to complete their quarterly review
procedures such that they will provide clearance on Roxio's quarterly financial
statements on the same date that Adaptec's Auditors provide clearance on
Adaptec's quarterly financial statements.

          (c) ANNUAL AND QUARTERLY FINANCIAL STATEMENTS. Roxio shall provide to
Adaptec on a timely basis all Information that Adaptec reasonably requires to
meet its schedule for the preparation, printing, filing, and public
dissemination of Adaptec's annual and quarterly financial statements. Without
limiting the generality of the foregoing, Roxio will provide all required
financial Information with respect to Roxio and its Subsidiaries to Roxio's
Auditors in a sufficient and reasonable time and in sufficient detail to permit
Roxio's Auditors to take all steps and perform all reviews necessary to provide
sufficient assistance to Adaptec's Auditors with respect to Information to be
included or contained in Adaptec's annual and quarterly financial statements.
Similarly, Adaptec shall provide to Roxio on a timely basis all Information that
Roxio reasonably requires to meet its schedule for the preparation, printing,
filing, and public dissemination of Roxio's annual and quarterly financial
statements. Without limiting the generality of the foregoing, Adaptec will
provide all required financial Information with respect to Adaptec and its
Subsidiaries to Adaptec's Auditors in a sufficient and reasonable time and in
sufficient detail to permit Adaptec's Auditors to take all steps and perform all
reviews necessary to provide sufficient assistance to Roxio's Auditors with
respect to Information to be included or contained in Roxio's annual and
quarterly financial statements.

          (d) IDENTITY OF PERSONNEL PERFORMING THE ANNUAL AUDIT AND QUARTERLY
REVIEWS. Roxio shall authorize Roxio's Auditors to make available to Adaptec's
Auditors both the personnel who performed or are performing the annual audits
and quarterly reviews of Roxio and work papers related to the annual audits and
quarterly reviews of Roxio, in all cases within a reasonable time prior to
Roxio's Auditors' opinion date, so that Adaptec's Auditors are able to perform
the procedures they consider necessary to take responsibility for the work of
Roxio's Auditors as it relates to Adaptec's Auditors' report on Adaptec's
financial statements, all within sufficient time to enable Adaptec to meet its
timetable for the printing, filing and public dissemination of Adaptec's annual
and quarterly statements. Similarly, Adaptec shall authorize Adaptec's Auditors
to make available to Roxio's Auditors both the personnel who performed or are
performing the annual audits and quarterly reviews of Adaptec and work papers
related to the annual audits and quarterly reviews of Adaptec, in all cases
within a reasonable time prior to Adaptec's Auditors' opinion date, so that
Roxio's Auditors are able to perform the procedures they consider necessary to
take responsibility for the work of Adaptec's Auditors as it relates to Roxio's
Auditors' report on Roxio's statements, all within sufficient time to enable
Roxio to meet its timetable for the printing, filing and public dissemination of
Roxio's annual and quarterly financial statements.

          (e) ACCESS TO BOOKS AND RECORDS. Roxio shall provide Adaptec's
internal auditors and their designees access to Roxio's and its Subsidiaries'
books and records so that Adaptec may conduct reasonable audits relating to the
financial statements provided by Roxio pursuant hereto as well as to the
internal accounting controls and operations of Roxio and its Subsidiaries.
Similarly, Adaptec shall provide Roxio's internal auditors and their designees
access to Adaptec's and its Subsidiaries' books and records so that Roxio may
conduct reasonable audits relating to the financial statements provided by
Adaptec pursuant hereto as well as to the internal accounting controls and
operations of Adaptec and its Subsidiaries.


                                      -11-
<PAGE>

          (f) NOTICE OF CHANGE IN ACCOUNTING PRINCIPLES. Roxio shall give
Adaptec as much prior notice as reasonably practical of any proposed
determination of, or any significant changes in, its accounting estimates or
accounting principles from those in effect on the Separation Date. Roxio will
consult with Adaptec and, if requested by Adaptec, Roxio will consult with
Adaptec's independent public accountants with respect thereto. Adaptec shall
give Roxio as much prior notice as reasonably practical of any proposed
determination of, or any significant changes in, its accounting estimates or
accounting principles from those in effect on the Separation Date.

          (g) CONFLICT WITH THIRD-PARTY AGREEMENTS. Nothing in SECTIONS 5.3 and
5.4 shall require Roxio to violate any agreement with any third parties
regarding the confidentiality of confidential and proprietary Information
relating to that third party or its business; PROVIDED, HOWEVER, that in the
event that Roxio is required under SECTIONS 5.3 AND 5.4 to disclose any such
Information, Roxio shall use all commercially reasonable efforts to seek to
obtain such customer's consent to the disclosure of such Information.

     SECTION 5.5 CONSISTENCY WITH PAST PRACTICES. At all times prior to the
Separation Date, Adaptec will cause the Roxio Business to continue to ship
products, invoice customers, make payments, maintain properties, manage
distribution channels and otherwise conduct business in the ordinary course,
consistent with past practices.

     SECTION 5.6 PAYMENT OF EXPENSES. Except as otherwise provided in this
Agreement, the Ancillary Agreements or any other agreement between the parties
relating to the Separation, the IPO or the Distribution, all costs and expenses
of the parties hereto in connection with the IPO (including underwriting
discounts and commissions but excluding internal costs, fees and expenses of
Adaptec) shall be paid by Roxio and all costs and expenses of the parties hereto
in connection with the Separation and Distribution (excluding internal costs,
fees and expenses of Roxio) shall be paid by Adaptec.

     SECTION 5.7 DISPUTE RESOLUTION. Resolution of any and all disputes, claims
and causes of action of any nature whatsoever (collectively, "DISPUTES"),
arising from or in connection with this Agreement, shall be exclusively governed
by and settled in accordance with the provisions of this SECTION 5.7.

          (a) NEGOTIATION. The parties shall make a good faith attempt to
resolve any Dispute arising out of or relating to this Agreement through
informal negotiation between appropriate representatives from each of Adaptec
and Roxio. If at any time either party feels that such negotiations are not
leading to a resolution of the Dispute, such party may send a notice to the
other party describing the Dispute and requesting a meeting of the senior
executives from each party. Within ten (10) business days after such notice is
given, each party shall select appropriate senior executives (e.g., director or
V.P. level) of each party who shall have the authority to resolve the matter and
shall meet to attempt in good faith to negotiate a resolution of the Dispute
prior to pursuing other available remedies. During the course of negotiations
under this SECTION 5.7(a), all reasonable requests made by one party to the
other for information, including requests for copies of relevant documents, will
be honored. The specific format for such negotiations will be left to the
discretion of the designated negotiating senior executives but may include the
preparation of agreed upon statements of fact or written statements of position
furnished to the other party. In the event


                                      -12-
<PAGE>

that any Dispute arising out of or related to this Agreement is not settled by
the parties within thirty (30) days after the first meeting of the negotiating
senior executives, either party may commence litigation with respect to the
Dispute. However, except as provided below in SECTION 5.7(b), neither party
shall commence litigation against the other party to resolve the Dispute (i)
until the parties try in good faith to settle the Dispute by negotiation for at
least thirty (30) days after the first meeting of the negotiating senior
executives or (ii) until forty (40) days after notice of a Dispute is given by
either party to the other party, whichever occurs first.

          (b) PROCEEDINGS. Any Dispute regarding the following is not required
to be negotiated prior to seeking relief from a court of competent jurisdiction:
breach of any obligation of confidentiality; infringement, misappropriation, or
misuse of any intellectual property right; or any other claim where interim
relief from the court is sought to prevent serious and irreparable injury to a
party. However, the parties shall make a good faith effort to negotiate such
Dispute, according to SECTION 5.7(a), while such court action is pending.

          (c) CONTINUITY OF SERVICE AND PERFORMANCE. Unless otherwise agreed in
writing, the parties will continue to provide service and honor all other
commitments under this Agreement and each Ancillary Agreement during the course
of dispute resolution pursuant to the provisions of this SECTION 5.7 with
respect to all matters not subject to such dispute, controversy or claim.

     SECTION 5.8 GOVERNMENTAL APPROVALS. To the extent that the Separation
requires any Governmental Approvals, the parties will use their reasonable
commercial efforts to obtain any such Governmental Approvals.

     SECTION 5.9 REPRESENTATIONS AND WARRANTIES. Adaptec hereby represents and
warrants as follows:

          (a) ORGANIZATION, GOOD STANDING AND QUALIFICATION. Adaptec, Adaptec
Manufacturing Singapore and each of the Transferred Subsidiaries are
corporations duly organized, validly existing and in good standing under the
laws of the respective jurisdictions under which they are incorporated and have
all requisite corporate power and authority to carry on their business as
currently conducted. Adaptec, Adaptec Manufacturing Singapore and each of the
Transferred Subsidiaries are duly qualified to transact business and are in good
standing in each jurisdiction in which the failure to so qualify would have a
material adverse effect on the Roxio Business.

          (c) CORPORATE POWER. Each of Adaptec, and Adaptec Manufacturing
Singapore, as applicable, has all requisite legal and corporate power to (i)
execute and deliver this Agreement, the Ancillary Agreements and all applicable
exhibits and schedules attached hereto and thereto at such times as are
contemplated by this Agreement and the Ancillary Agreements; and (ii) perform
its obligations hereunder and thereunder.

          (d) NO OTHER REPRESENTATIONS OR WARRANTIES. Adaptec does not, in this
Agreement or any other agreement, instrument or document contemplated by this
Agreement, make any representation as to, warranty of or covenant with respect
to:

               (i) the value of any asset or thing of value to be transferred to
Roxio;


                                      -13-
<PAGE>

               (ii) the freedom from encumbrance of any asset or thing of value
to be transferred to Roxio;

               (iii) the absence of defenses or freedom from counterclaims with
respect to any claim to be transferred to Roxio; or

               (iv) the legal sufficiency of any assignment, document or
instrument delivered hereunder to convey title to any asset or thing of value
upon its execution, delivery and filing.

          (e) RISK ASSOCIATED WITH TRANSFERRED ASSETS. Except as may expressly
be set forth herein or in any Ancillary Agreement, all assets to be transferred
to Roxio shall be transferred "AS IS, WHERE IS" and Roxio shall bear the
economic and legal risk that any conveyance shall prove to be insufficient to
vest in Roxio good and marketable title, free and clear of any lien, claim,
equity or other encumbrance.

     SECTION 5.10 COOPERATION IN OBTAINING NEW AGREEMENTS. Adaptec understands
that, prior to the Separation Date, Roxio has derived benefits under certain
agreements between Adaptec and third parties, which agreements are not being
assigned to Roxio in connection with the Separation. Upon the request of Roxio,
Adaptec agrees to make introductions to appropriate Roxio personnel to Adaptec's
contacts at such third parties, and agrees to provide reasonable assistance to
Roxio, at Adaptec's own expense, so that Roxio may obtain agreements from such
third parties under substantially equivalent terms and conditions, including
financial terms and conditions, that apply to Adaptec. Such assistance may
include, but is not limited to, (i) requesting and encouraging such third
parties to enter into such agreements with Roxio, (ii) attending meetings and
negotiating sessions with Roxio and such third parties, and (iii) participating
in buying consortiums with Roxio. Adaptec also understands that there are
certain agreements between Adaptec and third parties, which agreements are being
assigned to Roxio in connection with the Separation but which may require the
consent of the applicable third party. Upon the request of Roxio, Adaptec agrees
to assist Roxio in seeking and obtaining the consent of such third parties to
such assignment. The parties expect that the activities contemplated by this
SECTION 5.10 will be substantially completed by the Distribution Date, but in no
event will Adaptec have any obligations hereunder after the first anniversary of
the Distribution Date.

     SECTION 5.11 PROPERTY DAMAGE TO ROXIO ASSETS PRIOR TO THE SEPARATION DATE.
In the event of any property damage to any Roxio Assets prior to the Separation
Date, Adaptec shall repair or otherwise address such damage in the ordinary
course of business consistent with past practices; PROVIDED, HOWEVER, that
nothing in this clause shall restrict Adaptec from disposing of any Assets in
the ordinary course of business consistent with past practices.

     SECTION 5.12 ASSET TRANSFERS IN CONNECTION WITH SEPARATION. Adaptec
shall use its best efforts to have Adaptec Mfg (S) Pte Ltd. ("AMS"), a
