                                                                  EXECUTION COPY

                              RETENTION AGREEMENT

        This Retention Agreement (the "Agreement") is made by and between MTS,
Incorporated ("MTS") and Keith Cahoon ("Director"). Director is currently
employed by Tower Records, K.K. (the "Company"), a wholly-owned subsidiary of
MTS, as its Representative Director, Senior Vice President and Director of Asian
Operations. Director is a key contributor to the Company's success, and thus it
is now MTS's desire to incent Director to remain employed with the Company. As a
result, Director and MTS agree as set forth below.

        1. Loyalty. Director agrees that during the remainder of his employment
with the Company, he will devote his full business time and attention to his
position, refrain from engaging in any activity that is detrimental to the best
interests of the Company, perform his assignments and duties for the Company in
a professional and competent manner to the reasonable satisfaction of the
Company, and, if the occasion arises, cooperate in the orderly transition of the
Company to new ownership or management.

        2. Retention. In exchange for the agreements set forth in this
Agreement, Director agrees to remain employed by the Company (or any successor
to the Company) unless otherwise directed in writing by the Company until the
earliest of: (i) 6 months after the closing of any transaction described in
Paragraph 3 below, (ii) December 31, 2002 or (iii) death of Director.

        3. Success Fee. Provided that Director has not materially breached his
agreements contained in this Agreement, Director shall earn additional
compensation in the event of a Change of Control (as defined below) of the
Company occurs on or before March 31, 2003. In the event of a Change of Control
of the Company occurs on or before March 31, 2003, a "Success Fee" equal to
95,480,000 Japanese yen shall be payable by MTS to Director. Half of the Success
Fee will be paid by MTS immediately upon such Change of Control. The remaining
amount of the Success Fee will be paid by MTS six (6) months after such Change
of Control, provided such Change of Control occurs on or before March 31, 2003,
unless Director is earlier terminated by the Company without cause, in which
case payment of such remaining amount shall be made within five (5) days of such
termination. Payment of the Success Fee will be subject to applicable
withholding taxes. Notwithstanding anything to the contrary herein (but subject
to Director not materially breaching the agreements contained in this
Agreement), Director shall be entitled to receive the Success Fee in the event
that during the period from the date hereof until the earlier of (x) the Change
of Control of the Company and (y) March 31, 2003, (i) the Company terminates
employment of Director without cause or (ii) MTS removes Director from the
office of a director of the Company without cause or does not reappoint Director
to the office of a director of the Company without cause. For purposes of
Paragraph 3, "Change of Control" shall mean any of the following: (i) the direct
or indirect sale or exchange in a single or series of related transactions of
more than fifty percent (50%) of the voting stock of the Company; (ii) a merger
or consolidation with an unrelated third party in which the Company is a party;
or (iii) the sale, exchange or transfer of all or substantially all of the
assets of the Company, wherein MTS shall no longer retain immediately after such
transaction direct or indirect beneficial ownership of at least fifty percent
(50%) of the total combined voting power of the outstanding voting stock of the
Company or the corporation or corporations to which the assets of the Company
were transferred, as the case may be.

        4. Release of Claims. (a) As additional consideration for the agreements
set forth in this Agreement, Director agrees to execute and deliver on the date
of execution of this

<PAGE>

Agreement a general release of known and unknown claims, effective through the
date of this Agreement, in a form satisfactory to the Company and MTS, which
release shall be substantially similar to Exhibit "A" attached hereto.

               (b) Each payment of a portion of the Success Fee to Director is
conditioned upon Director's execution and delivery to MTS of a general release
of known and unknown claims, effective through the date of the payment providing
the consideration for the release, in a form satisfactory to MTS, which release
shall be substantially similar to Exhibit "B" attached hereto.

        5. Proprietary Rights/Assignment of Inventions. As part of Director's
responsibilities for the Company, he is entrusted with sensitive information of
a confidential nature concerning the business of the Company and/or its parent
MTS and their respective affiliates (referred to collectively and with their
successors as the "Company Group"). As additional consideration for the promises
regarding the payment of the Success Fee, Director agrees as follows:

               (a) Proprietary Information. "Proprietary Information" includes
any information (i) applicable to the business of the Company Group; or (ii)
applicable to the business of any client or customer of the Company Group, which
may be made known to Director by the Company Group or by any client or customer
of the Company Group, or learned by Director in such context during the period
of his employment. By way of illustration, but not limitation, Proprietary
Information includes any and all technical and non-technical information in
written, oral, electronic or other form, concerning research, experimental work,
development, design details and specifications, engineering, techniques,
sketches, drawings, models, Inventions (defined below), know-how, processes,
apparatus, equipment, algorithms, software programs, software source documents,
and formulae related to the current, future and proposed products and services,
financial information, tax records, personnel history or actions, computer
passwords, procurement requirements, purchasing, manufacturing, customer lists,
business forecasts, sales and merchandising and marketing plans and information.
"Proprietary Information" also includes any abstract or summary of Proprietary
Information. "Proprietary Information" also includes all materials (including
without limitation, documents, drawings, models, apparatus, sketches, designs,
lists, and all other tangible media of expression) that the Company Group or any
officers or directors of entities within the Company Group provides Director.
Notwithstanding the foregoing, Proprietary Information shall not include
information that is generally known in the trade or industry not as a result of
a breach of this Agreement and Director's own skill, knowledge, know-how and
experience.

               (b) Ownership of Proprietary Information. The Company Group (or,
as applicable, its assigns, and its clients or customers) owns all right, title
and interest (including all patent, trademark, copyright, trade secret, and
other intellectual property rights) in the Proprietary Information.

               (c) Nondisclosure of Proprietary Information. Director's
employment creates a relationship of confidence and trust between the Company
and Director with respect to any Proprietary Information. Director will keep in
confidence and trust all Proprietary Information, and will not use or disclose
any Proprietary Information or anything directly relating to it without the
prior written consent of MTS, except to the extent necessary to perform
Director's authorized duties for the Company, provided that Director takes
reasonable and appropriate precautions to prevent the unauthorized or further
use or disclosure of Proprietary Information.

                                       2
<PAGE>

               (d) Return of Materials. Upon termination of Director's
employment or at any time at the request of the Company before termination,
Director will deliver to the Company all written and tangible material in his
possession that incorporate any Proprietary Information or relates to the
Company Group's business, or the business of the Company Group's present, past
or prospective clients or customers.

               (e) Inventions. The term "Inventions" means any and all new or
useful art, discovery, improvement, technical development, idea, or invention
whether or not patentable, and all related know-how, designs, maskworks,
trademarks, formulae, processes, manufacturing techniques, trade secrets, ideas,
artwork, software or other copyrightable or patentable works.

               (f) Ownership of Company Inventions. Director will promptly
disclose to and describe to the Company, and hereby assigns and agrees to assign
to the Company or its designee, Director's entire right, title, and interest in
and to all Inventions (and any associated patent, trademark, copyright, trade
secret, and other intellectual property rights) that he may solely or jointly
make, develop or reduce to practice during the period of his employment
(including, since the beginning of his employment) with the Company (a) that
related at the time of conception or reduction to practice to the Company's
business or actual or demonstrably anticipated research or development, or (b)
that were developed on any amount of the Company's time or with the use of any
of the Company Group's equipment, supplies, facilities or trade secret
information, or (c) that resulted from any work Director performed for the
Company Group ("Company Inventions"). Notwithstanding anything contrary herein,
MTS acknowledges and agrees and shall cause the Company to acknowledge that
Director shall retain all rights, title and interest in articles and columns
which Director has published or will publish in trade or other magazines during
his employment with the Company, whether or not such articles or columns were
created with the use of any of the Company Group's equipment, supplies or
facilities.

               (g) Cooperation in Perfecting Rights to Inventions. Director
agrees to perform, during and after his employment, all reasonable acts that the
Company Group deems necessary or desirable to permit and assist the Company
Group, at its expense, in obtaining and enforcing the full benefits, enjoyment,
rights and title throughout the world in the Inventions hereby assigned to the
Company. Such acts may include, but are not limited to, execution of documents
and assistance or cooperation in the registration and enforcement of applicable
patents, copyrights, maskworks or other legal proceedings.

               (h) Survival. The obligations in this Paragraph 5 (h) shall
survive the termination of Director's employment with the Company for any
reason, (ii) inure to the benefit of successors and assigns of the Company
Group, and (iii) are binding upon Director's heirs and legal representatives.

        6. Non-solicitation covenant. During his employment with the Company,
and for a period of one (1) year following the termination of his employment for
any reason, Director shall not directly or indirectly recruit, solicit, or
induce any person who is, or who subsequently becomes, an employee, contractor
or consultant of the Company Group, to terminate his or her relationship with
the Company Group.

        7. Cooperation. During and after his employment, Director agrees to make
himself available upon reasonable request of the Company or MTS to furnish
information, provide

                                       3
<PAGE>

truthful testimony, speak with the Company's and/or MTS' attorneys or otherwise
assist the Company and/or MTS in the prosecution or defense of any legal action
in which the Company, MTS, and/or any of their affiliates, employees, officers
or directors are a party and that relates to Director's employment with the
Company or about which Director has relevant knowledge. Director will be
reimbursed for all reasonable expenses incurred in providing assistance
requested by the Company unless Director is a defendant in the action, in which
case the Board will determine whether reimbursement, if lawful, is appropriate.

        8. Taxes. Director agrees that he shall bear full responsibility for
complying with all applicable requirements of any relevant taxing authority(ies)
concerning any payment made under this Agreement, including the payment of any
additional tax liability that may arise with respect to any Success Fee paid by
the Company. Director agrees that he shall indemnify and defend and hold the
Company Group harmless from any and all such tax liability of Director,
including, but not limited to, taxes, penalties, attorneys' fees and/or interest
that may be assessed by any taxing authority in connection with any payment made
under this Agreement.

        9. Confidentiality. Director agrees that he shall not directly or
indirectly disclose any of the terms of this Agreement, including the amount of
the payments referred to Paragraph 3 above, to anyone other than his spouse or
counsel, except as such disclosure may be required for accounting or tax
reporting purposes or as otherwise may be required by law or to carry out the
terms of this Agreement, and provided that anyone to whom terms of this
Agreement are disclosed similarly agrees to maintain them in confidence subject
to this paragraph.

        10. Injunctive Relief. A breach of any of the promises or agreements
contained in Paragraphs 5, 6, 7 or 9 of this Agreement will result in
irreparable and continuing damage to the Company or Company Group for which
there will be no adequate remedy at law, and the Company or Company Group, as
applicable, shall be entitled to injunctive relief and/or a decree for specific
performance, and such other relief as may be proper (including monetary damages
if appropriate).

        11. Arbitration. The parties to this Agreement shall use their best
efforts to settle amicably any disagreement, dispute, controversy or claim
arising out of or relating to the relationship between the parties or the
termination of that relationship, this Agreement or the interpretation hereof or
any arrangements relating hereto or contemplated herein or the breach,
termination or invalidity hereof (each such disagreement, dispute, controversy
or claim shall be referred to as a "Dispute"). If a Dispute is not settled
amicably within ninety (90) days after receipt by one party of the other party's
request for amicable settlement, either party may at any time after the
expiration of such 90-day period submit such Dispute to arbitration pursuant to
the rules of arbitration of the Japan Commercial Arbitration Association. Such
arbitration shall be the exclusive means of final settlement of any Dispute. The
place of arbitration shall be Tokyo, Japan. The language used in the arbitration
shall be the English language. Any decision or award of the arbitral tribunal
shall be final and binding upon the parties to the arbitration. The parties to
this Agreement hereby waive to the extent permitted by law any rights to appeal
or to review of such award by any court or tribunal and agree that the arbitral
award may be enforced against the parties to the arbitration or their assets
wherever they may be found and that a judgment upon the arbitral award may be
entered in any court having jurisdiction thereof. Provided, however, that this
arbitration agreement will not preclude either party from seeking, before or
after commencement of such 90-day period, from any court with jurisdiction to
issue preliminary injunction, attachment or other form of provisional remedy in
aid of arbitration. In

                                       4
<PAGE>

addition to the authority conferred on an arbitral tribunal by the rules of
arbitration specified above, such arbitral tribunal shall also have the
authority to grant injunctive relief and/or specific performance, and such other
relief as may be proper (including monetary damages if appropriate).

        12. Miscellaneous Provisions.

               (a) Waiver. No waiver by either party of any breach of, or of
compliance with, any condition or provision of this Agreement by the other party
shall be considered a waiver of any other condition or provision or of the same
condition or provision at another time.

               (b) Choice of Law. The laws of Japan shall govern the validity,
interpretation, construction and performance of this Agreement.

               (c) Severability. If any provision of this Agreement is found to
be unenforceable by an arbitrator or a court of competent jurisdiction, this
shall not affect the validity or enforceability of the other provisions hereof,
which shall remain in full force and effect.

               (d) Counterparts. This Agreement may be executed in counterparts,
each of which shall be deemed an original, but all of which together will
constitute one and the same instrument.

               (e) Successor and Assigns. Director shall have no right to assign
any of his obligations or duties under this Agreement to any other person or
entity. Subject to the foregoing, this Agreement shall be binding upon the
parties hereto and their successors and assigns and shall inure to the benefit
of the parties hereto and their successors and assigns. All rights of Director
hereunder shall inure to the benefit of, and be enforceable by Director's
personal or legal representatives, executors, administrators, successors, heirs,
distributees, devisees and legatees.

        13. Attorney Consultation. Director acknowledges that he has sought the
advice of independent legal counsel of his own choice during the negotiation of
this Agreement and that he has executed this Agreement after consultation with
such independent legal counsel. The language of this Agreement shall be
construed as a whole according to its fair meaning and not strictly for or
against any of the parties. Upon receipt of appropriate supporting
documentation, the Company shall reimburse Director for one-half of his
reasonable legal fees actually incurred in reviewing and negotiating the terms
of this Agreement, up to a maximum reimbursement of $5,000.00.

        14. Entire Agreement/Modification. This Agreement constitutes the entire
agreement between Director and the Company regarding the Success Fee, and it
supersedes all previous negotiations, representations and agreements between the
parties regarding those subjects. This Agreement may not be modified except by a
supplemental written agreement signed by Director and an authorized officer of
the Company.

        1. In exchange for agreements set forth in the Retention Agreement
between MTS, Incorporated ("MTS") and Keith Cahoon ("Director") of October 11,

Tower Records, K.K. (the "Company") and MTS and each of their respective
subsidiaries, affiliates, shareholders, investors, directors, officers,
employees, agents, attorneys, insurers, legal predecessors, successors and
assigns of and from any and all claims, actions and causes of action, whether
now known or unknown, which Director now has, or at any other time had, or shall
or may have against those released parties relating to or arising out of their
employment relationship, the termination of their employment relationship, or
any other matter, cause, fact, thing, act or omission whatsoever occurring or
existing at any time up to and including the date of execution of this General
Release, including, but not limited to, any claims of breach of contract, breach
of fiduciary duty, wrongful termination, retaliation, fraud, defamation,

orientation, disability or other discrimination or harassment (collectively
referred to as the "Released Matters").

        2. In executing this General Release and receiving the consideration
mentioned above, Director affirms that he intends to release all known and
unknown claims that he has or may have against the parties listed above.
Director warrants and represents that he is the sole and lawful owner of all

assigned or transferred or purported to assign or transfer to any other person
or entity any Released Matter or any part or portion thereof. Director further
represents and warrants that he has no claims of any kind pending against any of
the parties listed above. Director agrees not to commence any action, charge,
claim or other proceeding against any of the parties listed above based on any

        3. Notwithstanding anything to the contrary herein, Director does not
release nor discharge (i) the Company from its obligations to pay all wages and
benefits, including without limitation, retirement allowance for directors, that
he earned until and including the date of execution of this General Release; and
(ii) MTS from Director's right to enforce the terms of the Retention Agreement.

        4. Director agrees that he will not make, repeat or authorize any
statements, comments, remarks or publications of any type that would disparage
or tend to disparage the reputation of the Company, MTS or their respective
current or former parent, subsidiaries, affiliates, officers, directors,
employees or shareholders at any time; provided, however, that this provision
shall not prevent Director from responding truthfully to a subpoena or as
otherwise compelled by law.

        5. This General Release shall be governed by and construed in accordance
with the laws of Japan.

        6. If an arbitrator or a court of competent jurisdiction finds any
provision of this General Release to be unenforceable for any reason, the
remainder of this General Release shall continue in full force and effect.

or shall or may have against those released parties relating to or arising out
of their employment relationship, the termination of their employment
relationship, or any other matter, cause, fact, thing, act or omission
whatsoever occurring or existing at any time up to and including the date of
execution of this General Release, including, but not limited to, any claims of
breach of contract, breach of fiduciary duty, wrongful termination, retaliation,
fraud, defamation, infliction of emotional distress or national origin, race,
age, sex, sexual orientation, disability or other discrimination or harassment
(collectively referred to as the "Released Matters").

        2. In executing this General Release and receiving the consideration
mentioned above, Director affirms that he intends to release all known and
unknown claims that he has or may have against the parties listed above.
Director warrants and represents that he is the sole and lawful owner of all
right, title and interest in and to all of the respective Released Matters and
that he has not heretofore voluntarily, by operation of law or otherwise,
assigned or transferred or purported to assign or transfer to any other person
or entity any Released Matter or any part or portion thereof. Director further
represents and warrants that he has no claims of any kind pending against any of
the parties listed above. Director agrees not to commence any action, charge,
claim or other proceeding against any of the parties listed above based on any
of the Released Matters, to the fullest extent permitted by law.

        3. Notwithstanding anything to the contrary herein, Director does not
release nor discharge (i) the Company from its obligations to pay all wages and
benefits, including without limitation, retirement allowance for directors, that
he earned until and including the date of execution of this General Release; and
(ii) MTS from Director's right to enforce the terms of the Retention Agreement.

        4. Director agrees that he will not make, repeat or authorize any
statements, comments, remarks or publications of any type that would disparage
or tend to disparage the reputation of the Company, MTS or their respective
current or former parent, subsidiaries, affiliates, officers, directors,
employees or shareholders at any time; provided, however, that this provision
shall not prevent Director from responding truthfully to a subpoena or as
otherwise compelled by law.

        5. This General Release shall be governed by and construed in accordance
with the laws of Japan.

        6. If an arbitrator or a court of competent jurisdiction finds any
provision of this General Release to be unenforceable for any reason, the
remainder of this General Release shall continue in full force and effect.
