      This First Amended and Restated Master Separation and Distribution
Agreement (this "AGREEMENT") is entered into as of February 28, 2001, between

      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

pro rata distribution following the Separation, 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, Adaptec and Roxio previously entered into a Master Separation and
Distribution Agreement dated September 21, 2000 (the "PRIOR AGREEMENT"), which,
among other things, contemplated that prior to the Distribution Roxio would
effect a registered initial public offering of its Common Stock ( the "IPO");

      WHEREAS, the Board of Directors of each of Adaptec and Roxio no longer
desire Roxio to effect the IPO;

      WHEREAS, Adaptec and Roxio desire to terminate in all respects the Prior
Agreement and enter into this Agreement; 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.

      SECTION 3.1 TRANSACTIONS PRIOR TO THE DISTRIBUTION. Subject to the
conditions specified in SECTION 3.4, Adaptec and Roxio shall use their
reasonable commercial efforts to consummate the Distribution. Such efforts shall
include, but not necessarily be limited to, those specified in this SECTION 3.1

            (a)   REGISTRATION STATEMENT. Roxio, with the cooperation and
assistance of Adaptec, shall register its common stock under Section 12 of the
Securities Exchange Act of 1934 (the "EXCHANGE ACT") by filing a Form 10
Registration Statement, and such amendments or supplements thereto, as may be
necessary in order to cause the same to become and remain effective as required
by law, including, but not limited to, filing such amendments to the Form 10
Registration Statement as may be required by the Securities and Exchange
Commission (the "COMMISSION") or federal, state or foreign securities laws.
Adaptec and Roxio shall also cooperate in preparing and filing with the
Commission any registration statements or amendments thereof which are required
to reflect the establishment of, or amendments to, any employee benefit and
other plans necessary or appropriate in connection with the Separation, the
Distribution or the other transactions contemplated by this Agreement.

            (b)   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.

            (c)   OTHER MATTERS. Adaptec and Roxio shall consult with each other
and their financial advisors regarding the timing, pricing and other material
matters with respect to the Distribution.

            (d)   BLUE SKY. Adaptec and Roxio shall take all such actions as may

                                                                             -4-

            (e)   NASDAQ LISTING. Roxio shall prepare, file and use reasonable

      SECTION 3.2 THE DISTRIBUTION.

            (a)   DELIVERY OF SHARES FOR DISTRIBUTION. Subject to SECTION 3.3
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 3.3 and 3.5, 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.

necessary and appropriate to cause the conditions set forth in SECTION 3.3 to be
satisfied and to effect the Distribution on the Distribution Date.


      SECTION 3.3 CONDITIONS TO DISTRIBUTION. The parties hereto shall use their
reasonable commercial efforts to effect the Distribution prior to April 30,
2001, or as soon thereafter as practicable. The obligations of the parties to
consummate the Distribution shall be conditioned on the satisfaction, or written
waiver by Adaptec, of the following conditions:

            (a)   IRS RULING. Adaptec shall have received an opinion from
PricewaterhouseCoopers, LLP in form and substance satisfactory to Adaptec (in
its sole discretion), 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


                                                                             -5-

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

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

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

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.

possession and operating control thereof and to permit Roxio and its

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 4.3 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 4.3 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 4.3 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. 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.


                                                                             -8-


<Page>


            (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 4.3 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 4.3(C).

            (e)   OTHER AGREEMENTS PROVIDING FOR EXCHANGE OF INFORMATION. The
rights and obligations granted under this SECTION 4.3 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 4.7 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 4.4 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 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


                                                                             -9-


<Page>


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.

            (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


                                                                            -10-


<Page>


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 4.3
and 4.4 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 4.3 AND 4.4 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 4.5 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 4.6 PAYMENT OF EXPENSES. Except as otherwise provided in this
Agreement, the Ancillary Agreements or any other agreement between the parties
relating to the Separation or the Distribution, all costs and expenses of the
parties hereto in connection with the Separation and Distribution (excluding
internal costs and expenses of Roxio) shall be paid by Adaptec.

      SECTION 4.7 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 4.7.

            (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 4.7(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 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.


                                                                            -11-


<Page>


            (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 4.7(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 4.7 with
respect to all matters not subject to such dispute, controversy or claim.

      SECTION 4.8 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 4.9 REPRESENTATIONS AND WARRANTIES . Adaptec hereby represents and
warrants as follows:

            (a)   ORGANIZATION, GOOD STANDING AND QUALIFICATION. Adaptec,
Adaptec MFG(S) PTE LTD, a Singapore corporation ("AMS"), 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, AMS 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.

            (b)   CORPORATE POWER. Each of Adaptec, and AMS, 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.

            (c)   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;

                  (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


                                                                            -12-



<Page>


                  (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.

            (d)   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 4.10 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 4.10 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 4.11 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 4.12 ASSET TRANSFERS IN CONNECTION WITH SEPARATION. Adaptec shall
use its best efforts to have AMS transfer to Roxio CI Ltd., a Cayman Island
corporation, prior to the Separation Date, all of AMS's interest in any
intellectual property relating to the Roxio Business owned by AMS and AMS's
ownership of CG1 Gmbh, a German corporation, pursuant to the International
Transfer of Assets Agreement substantially in the form attached hereto as
EXHIBIT L.


                                                                            -13-
