is effective as of November___, 2000 (the "Effective Date"), between Adaptec,
Inc., a Delaware corporation ("Adaptec"), having an office 691 South Milpitas
Boulevard, Milpitas, CA 95035, and Roxio, Inc., a Delaware corporation
("Roxio"), having an office at 461 South Milpitas boulevard, Milpitas,

         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;

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.

(and their) right, title and interest in and to any and all causes of action

<PAGE>

all lawful and just acts, that may be or become necessary for prosecuting,
sustaining, obtaining continuations, continuations-in-part and divisionals
of, or reissuing or re-examining, said Assigned Patents and for evidencing,
maintaining, recording and perfecting Roxio's rights to said Assigned
Patents, including but not limited to execution and acknowledgement of (and
causing its Subsidiaries to execute and acknowledge) assignments and other
instruments in a form reasonably required by Roxio for each Patent
jurisdiction.

         2.2  PRIOR GRANTS. Roxio acknowledges and agrees that the foregoing
assignments are subject to any and all licenses or other rights that may have
been granted by Adaptec or its Subsidiaries with respect to the Assigned
Patents prior to the Effective Date. Adaptec shall respond to reasonable
inquiries from Roxio regarding any such prior grants.

         2.3  ASSIGNMENT DISCLAIMER. EACH PARTY ACKNOWLEDGES AND AGREES THAT
THE FOREGOING ASSIGNMENTS ARE MADE ON AN "AS-IS," QUITCLAIM BASIS AND THAT
NEITHER PARTY NOR ANY SUBSIDIARY OF SUCH PARTY HAS MADE OR WILL MAKE ANY
WARRANTY WHATSOEVER, EXPRESS, IMPLIED OR STATUTORY, INCLUDING WITHOUT
LIMITATION ANY IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A
PARTICULAR PURPOSE, TITLE, ENFORCEABILITY, NON-INFRINGEMENT, OR VALIDITY OF
PATENT CLAIMS (ISSUED OR PENDING).

                                    ARTICLE 3

                                 PATENT LICENSES

         3.1  LICENSE TO WILD FILE PATENTS. Roxio hereby grants to Adaptec a
nonexclusive, irrevocable, fully paid-up, worldwide license, without the
right to grant sublicenses, under the Wild File Patents to make (including
the right to practice methods, processes and procedures), have made, use,
lease, sell, offer for sale and import any products and services embodying or
made in accordance with any invention of the Wild File Patents, but excluding
products within the Restricted Field.

         3.2  TRANSFER OF PRODUCT BY ADAPTEC. If Adaptec shall transfer to a
third party (a "Transferee") a product licensed under the Wild File Patents
under Section 3.1 (a "Transferred Product"), as part of a transfer of assets,
stock or other rights in a product line, then, after Adaptec's notification
to Roxio of such transfer, Adaptec may transfer its license for the
Transferred Product to the Transferee on the condition that Adaptec becomes
unlicensed for the Transferred Product (as that term is defined in the
agreement transferring the product from Adaptec to the Transferee ("Product
Transfer Agreement")). The foregoing shall not affect Adaptec's license under
the Wild File Patents with respect to any other product.

            Roxio hereby grants Adaptec an option for a royalty free license
under the Wild File Patents of the same scope as the license transferred to
the Transferee, provided that the scope of the license in such option shall
be reduced to conform with such restrictions (including time restrictions),
if any, on Adaptec's ability to compete with the Transferred Product as may
be agreed to between Adaptec and the Transferee. Adaptec may exercise such
option, by giving written notice to Roxio after such transfer, during such
time as Roxio holds such Wild File Patents and subject to any such
restrictions, and, if any such restrictions have been agreed to, including
with such notice a copy of the relevant sections of the Product Transfer
Agreement or related agreement that sets forth such restrictions.

         3.3  ADAPTEC LICENSE TO ROXIO FOR CURRENT PRODUCTS. Adaptec hereby
grants to Roxio a nonexclusive, irrevocable, fully paid-up, worldwide
license, without the right to grant sublicenses, under the Adaptec Patents to
make (including the right to practice methods, processes and procedures),
have made, use, lease, sell, offer for sale and import any products and
services that are commercially released by Roxio prior to or on the
Separation Date that embody or are made in accordance with any invention of
the Adaptec Patents ("Current Roxio Licensed Products").

         3.4  ROXIO LICENSE TO ADAPTEC FOR CURRENT PRODUCTS. Roxio hereby
grants to Adaptec a nonexclusive, irrevocable, fully paid-up, worldwide
license, without the right to grant sublicenses, under the Assigned Patents
to make (including the right to practice methods, processes and procedures),
have made, use, lease, sell, offer for sale and import any products and
services that are commercially released by Adaptec prior to or on the
Separation Date that embody or are made in accordance with any invention of
the Assigned Patents ("Current Adaptec Licensed Products").

         3.5  ADAPTEC LICENSE TO ROXIO FOR SUBSEQUENT PRODUCTS. Adaptec
hereby grants to Roxio a nonexclusive, irrevocable, fully paid-up, worldwide
license, without the right to grant sublicenses, under the Adaptec Patents to
make (including the right to practice methods, processes and procedures),
have made, use, lease, sell, offer for sale and import products or services
containing functionality (a) embodied in a Current Roxio Licensed Product,
and (b) embodying or made in accordance with any invention(s) of the Adaptec
Patents. Such license shall not extend to any functionality or feature of the
product or service not embodied in a Current Roxio Licensed Product.

         3.6  ROXIO LICENSE TO ADAPTEC FOR SUBSEQUENT PRODUCTS. Roxio hereby
grants to Adaptec a nonexclusive, irrevocable, fully paid-up, worldwide
license, without the right to grant sublicenses, under the Assigned Patents
to make (including the right to practice methods, processes and procedures),
have made, use, lease, sell, offer for sale and import products or services
containing functionality (a) embodied in a Current Adaptec Licensed Product,
and (b) embodying or made in accordance with any invention(s) of the Assigned
Patents. Such license shall not extend to any functionality or feature of the
product or service not embodied in a Current Adaptec Licensed Product.

         3.7  NO LICENSE GRANTED UNDER EXCLUSIVELY LICENSED PATENTS. Not
withstanding any other statement in this Agreement, no license is granted by
Roxio to Adaptec under any Patent to the extent such Patent was exclusively
licensed or exclusively optioned to a third party by Adaptec before the
Separation Date.

                                       -6-

<PAGE>

         3.8  EXTENSION OF LICENSES TO SUBSIDIARIES. Notwithstanding any
prohibition on sublicenses set forth in this Article 3, the licenses granted
in this Agreement shall include the right of the parties hereto to sublicense
their respective Subsidiaries. Each sublicensed Subsidiary shall be bound by
the terms and conditions of this Agreement as if it were named herein in the
place of the party with whom the sublicense originated. If a sublicensed
Subsidiary ceases to be a Subsidiary and holds any patents or patent
applications under which a party hereto is licensed, such license will
continue for the life of such patents or patent applications. Any sublicense
granted to a Subsidiary shall terminate on the date such Subsidiary ceases to
be a Subsidiary.

         3.9  LICENSE RIGHTS AS TO CERTAIN OTHER PATENTS. If Adaptec holds
rights under any patent that would qualify as one of the Adaptec Patents
solely but for the requirement of payment of royalties for the granting of
licenses thereunder ("Royalty Bearing Patent"), Adaptec agrees, within a
reasonable time of Roxio's written request, to grant Roxio a license under
the Royalty Bearing Patent ("Royalty Bearing Patent License"). Such Royalty
Bearing Patent License shall be granted under the terms and conditions of
licenses granted to Roxio herein under the Adaptec Patents, but only during
such time as Adaptec holds such rights under the Royalty Bearing Patent and
at the royalty rate which Adaptec is obligated to pay for the grant of such

                             ADDITIONAL OBLIGATIONS

         4.1  ADDITIONAL OBLIGATIONS WITH REGARD TO ASSIGNED PATENTS

              (a) The parties will cooperate to effect a smooth transfer of
the responsibility for prosecution, maintenance and enforcement of the
Assigned Patents and Wild File Patents from Adaptec or any Subsidiary to
Roxio. Until such transfer has been effected, Adaptec agrees to continue the
prosecution and maintenance of, and ongoing litigation (if any) with respect
to, the Assigned Patents and Wild File Patents (including payment of
maintenance fees), and to maintain its files and records relating to the
Assigned Patents and Wild File Patents using the same standard of care and
diligence that it uses with respect to Adaptec's Patents. Roxio will
reimburse Adaptec for all actual and reasonable expenses (excluding the value
of the time of Adaptec employees) to continue to prosecute and maintain the
Assigned Patents and Wild File Patents after the Effective Date until the
transfer of responsibility for the Assigned Patents and Wild File Patents has
been completed and to continue any such ongoing litigation. The parties shall
agree on a case by case basis on compensation, if any, of Adaptec for the
value of time of Adaptec's employees as reasonably required in connection
with any such litigation. Adaptec will provide Roxio with the originals or
copies of its files relating to the Assigned Patents and Wild File Patents
upon such transfer or at such earlier time as the parties may agree.

              (b) Adaptec shall provide continuing reasonable support to
Roxio with respect to the Assigned Patents and Wild File Patents, including
by way of example the following:

                                       -7-

<PAGE>

                  (i)  executing all documents prepared by Roxio necessary
for prosecution, maintenance, and litigation of the Assigned Patents and Wild
File Patents,

                  (ii) making available to Roxio or its counsel, inventors
and other persons employed by Adaptec for interviews and/or testimony to
assist in good faith in further prosecution, maintenance or litigation of the
Assigned Patents and Wild File Patents, including the signing of documents
related thereto,

                  (iii) forwarding copies of all correspondence sent and
received concerning the Assigned Patents and Wild File Patents within a
reasonable period of time after receipt by Adaptec, and

                  (iv) making all relevant documents in the possession or
control of Adaptec and corresponding to the Assigned Patents and Wild File
Patents, or any licenses thereunder, available to Roxio or its counsel.

Any actual and reasonable out-of-pocket expenses associated with any such
assistance shall be borne by Roxio, expressly excluding the value of the time of
such Adaptec employees; provided, however, that in the case of assistance with
litigation, the parties shall agree on a case by case basis on compensation, if
any, of Adaptec for the value of the time of Adaptec's employees as reasonably
required in connection with such litigation.

         4.2  RECORDATION OF LICENSES

              (a) For any country, now or in the future, that requires the
express consent of all inventors or their assignees to the grant of licenses
or rights under Patents issued in such countries for Assigned Patents, Wild
File Patents or Adaptec Patents:

                  (i) each party shall give such consent, or shall obtain
such consent from its employees, its Subsidiaries or employees of any of its
Subsidiaries, as required to make full and effective any such licenses and
rights respecting any Patent license granted to a grantee hereunder by such
party; and

                  (ii) each party shall take steps that are reasonable under
the circumstances to obtain from Third Parties whatever other consents are
necessary to make full and effective such licenses and rights respecting any
Patent license purported to be granted by it hereunder. If, in spite of such
reasonable steps, such party is unable to obtain the requisite consents from
such Third Parties, the resulting inability of such party to make full and
effective its purported grant of such licenses and rights shall not be
considered to be a breach of this Agreement.

              (b) Each party agrees, without demanding any further
consideration, to execute (and to cause its Subsidiaries to execute) all
documents reasonably requested by the other party to effect recordation of
the license relationship between the parties created by this Agreement.

                                 CONFIDENTIALITY

         The terms of the Master Confidential Disclosure Agreement between the
parties shall apply to any Confidential Information which is the subject matter
of this Agreement.

                                    ARTICLE 6

                              TERM AND TERMINATION

         6.1  TERM OF AGREEMENT. The term of this Agreement shall be from the
Effective Date until the last to expire of the Assigned Patents and the Wild
File Patents.

         6.2  VOLUNTARY TERMINATION. By written notice to the other party,
either party may voluntarily terminate all or a specified portion of the
licenses and rights granted to it hereunder by the other party. Such notice
shall specify the effective date of such termination and shall clearly
specify any affected Patent, Patent application, Invention Disclosure,
product or service.

         6.3  SURVIVAL. Any voluntary termination of licenses and rights of a
party under Section 6.2 shall not affect such party's licenses and rights
with respect to any licensed product made or service furnished prior to such
termination, and shall not affect the licenses and rights granted to such
party hereunder.

         6.4  NO OTHER TERMINATION. Each party acknowledges and agrees that
its remedy for breach by the other party of the licenses granted to it
hereunder or of any other provision hereof, shall be, subject to the
requirements of Article 7, to bring a claim to recover damages and to seek
any other appropriate equitable relief.

                                    ARTICLE 7

                               DISPUTE RESOLUTION

         Resolution of any and all Disputes arising from or in connection
with this Agreement shall be exclusively governed by and settled in
accordance with the provisions of this Article 7.

         7.1  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
of a Dispute 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

                                       -9-

<PAGE>

prior to pursuing other available remedies. During the course of negotiations
under this Section 7.1, 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 7.2, 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.

         7.2  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 7.1, while such court
action is pending.

         7.3  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 Article 7
with respect to all matters not subject to such dispute, controversy or claim.

                                    ARTICLE 8

                             LIMITATION OF LIABILITY

         IN NO EVENT SHALL EITHER PARTY OR ITS SUBSIDIARIES BE LIABLE TO THE
OTHER PARTY OR ITS SUBSIDIARIES FOR ANY SPECIAL, CONSEQUENTIAL, INDIRECT,
INCIDENTAL OR PUNITIVE DAMAGES OR LOST PROFITS, HOWEVER CAUSED AND ON ANY THEORY
OF LIABILITY (INCLUDING NEGLIGENCE) ARISING IN ANY WAY OUT OF THIS AGREEMENT,
WHETHER OR NOT SUCH PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES;
PROVIDED, HOWEVER, THAT THE FOREGOING LIMITATIONS SHALL NOT LIMIT DAMAGES FOR
INFRINGEMENT OF ANY INTELLECTUAL PROPERTY RIGHTS TO THE EXTENT NOT LICENSED OR
COVENANTED HEREIN; PROVIDED FURTHER THAT THE FOREGOING LIMITATIONS SHALL NOT
LIMIT EACH PARTY'S INDEMNIFICATION OBLIGATIONS FOR LIABILITIES TO THIRD PARTIES
AS SET FORTH IN THE INDEMNIFICATION AND INSURANCE MATTERS AGREEMENT.

sale or sale of any product or service will be free from infringement of any
Patent or other intellectual property right of any Third Party.

         10.2 NO IMPLIED LICENSES. Nothing contained in this Agreement shall
be construed as conferring any rights by implication, estoppel or otherwise,
under any intellectual property right, other than the rights expressly
granted in this Agreement with respect to the Assigned Patents, Wild File
Patents and Adaptec Patents. Neither party is required hereunder to furnish
or disclose to the other any technical or other information except as
specifically provided herein.

         10.3 INFRINGEMENT SUITS. Neither party shall have any obligation
hereunder to institute any action or suit against Third Parties for
infringement of any Patent or to defend any action or suit brought by a Third
Party which challenges or concerns the validity of any Patent. Unless the
parties otherwise agree in writing, neither party shall have any right to
institute any action or suit against Third Parties for infringement of any
Patent owned by the other party.
