                                  ARTICLE III

                OTHER OBLIGATIONS OF THE LICENSOR AND LICENSEE
                ----------------------------------------------


     Section 3.01 - Use of Licensed Trademarks
     -----------------------------------------

     The Licensed Trademarks have acquired a reputation for high quality among
professionals and consumers around the world. The performance capability of the
Dolby Digital AC-3 audio system is such that LICENSOR is willing, by virtue of
this Agreement, to allow the use of the Licensed Trademarks on Licensed Products
or on the user interface to Licensed Products and in connection with their
advertising and marketing to indicate that the quality of such products conforms
with the general reputation for high quality associated with the Licensed
Trademarks. LICENSEE's use of the Licensed Trademarks shall be subject to the
obligations of this Agreement as well as detailed regulations issued from time
to time by LICENSOR. LICENSEE shall comply with the requirements of the body of
this Agreement and such additional regulations as LICENSOR may issue and shall
ensure that its subsidiaries, agents, distributors, and dealers throughout the
world comply with such requirements (in the case of any inconsistencies among
the body of this Agreement, the Dolby Digital Licensee Information Manual of
Appendix D and any additional regulations, the body of this Agreement shall
govern):

     (1)  LICENSEE shall prominently mark the Licensed Product or the user
interface to the Licensed Product in the following way:


                                 [LOGO] DOLBY
                                 D I G I T A L


     (2)  The mark specified in subsection (1) of this Section 3.01, shall also
be used at least once in a prominent manner in all advertising and promotions
for such Licensed Product; such usages shall be no less prominent and in the
same relative size as the most prominent third party other trademark(s)
appearing on such Licensed Product or in the advertising and promotion thereof.

     (3)  LICENSEE may not use the Licensed Trademarks in advertising and
promotion of a product not marked in accordance with subsection (1) of this
Section 3.01.
<PAGE>
 
     (4)  In every use of a Licensed Trademark, except on the main control
surface of a Licensed Product, LICENSEE shall give notice to the public that
such Licensed Trademark is a trademark by using the superscript letters "TM"
after the respective trademark, or by use of the trademark registration symbol
"(R)" (the capital letter R enclosed in a circle) as a superscript after the
respective trademark. LICENSOR shall inform LICENSEE as to which notice form is
to be used.

     (5)  LICENSEE shall use its best efforts to ensure that the appropriate
trademark notices, as set forth in subsection (3) above, appear in advertising
for such Licensed Products at the retail level.

     (6)  LICENSOR's ownership of Licensed Trademarks shall be indicated
whenever used by LICENSEE, whether use is on a product or on descriptive,
instructional, advertising, or promotional material, by the most relevant of the
following acknowledgments: "'Dolby' is a trademark of Dolby Laboratories", "The
'Double-D' symbol is a trademark of Dolby Laboratories", or "'Dolby' and the
'Double-D' symbol are trademarks of Dolby Laboratories." On Licensed Products
such words shall be used on an exposed surface, such as the back or the bottom.
LICENSEE shall use its best efforts to ensure that such an acknowledgment
appears in advertising at the retail level.

     (7)  Licensed Trademarks shall always be used in accordance with
established United States practices for the protection of trademark and service
mark rights, unless the requirements in the country or jurisdiction in which the
product will be sold are more stringent, in which case the practice of such
country or jurisdiction shall be followed. In no event shall any Licensed
Trademark be used in any way that suggests or connotes that it is a common,
descriptive or generic designation. Whenever the word "Dolby" is used, the
letter D shall be upper-case. The word "Dolby" shall be used only as an
adjective referring to a digital audio product, never as a noun or in any other
usage which may contribute to a generic meaning thereof. ln descriptive,
instructional, advertising, or promotional material or media relating to
Licensed Products, LICENSEE must use the Licensed Trademarks and expressions
which include the Licensed Trademark "Dolby" with an appropriate generic or
descriptive term (e.g. "Dolby Digital encoder", "Dolby Digital audio circuit",
"Dolby AC-3 transmission" etc.), with reference to Licensed Products and their
use.

     (8)  All uses of the Licensed Trademarks are subject to approval by
LICENSOR. LICENSOR reserves the right to require LICENSEE to submit proposed
uses to LICENSOR for written approval prior to actual use. Upon request of
LICENSOR, LICENSEE shall submit to LICENSOR samples of its own
<PAGE>
 
usage of the Licensed Trademarks and usage of the Licensed Trademarks by its
subsidiaries, agents, distributors, and dealers.

     (9)  Licensed Trademarks shall be used in a manner that distinguishes them
from other trademarks, service marks, symbols or trade names, including
LICENSEE's Trade Name and Trademarks.

     (10) LICENSEE may not use the Licensed Trademarks on and in connection with
products that do not meet LICENSOR's quality standards.

     (11) LICENSEE may not use the Licensed Trademarks on and in connection with
products other than Licensed Products.

     Section 3.02 - Ownership of the Licensed Trademarks
     ---------------------------------------------------

     LICENSEE acknowledges the validity and exclusive ownership by LICENSOR of
the Licensed Trademarks.

     LICENSEE further acknowledges that it owns no rights in the Licensed
Trademarks nor in the tradename "Dolby Laboratories." LICENSEE acknowledges and
agrees that all rights that it may accrue in the Licensed Trademarks and in the
tradenames "Dolby Laboratories" will inure to the benefit of the owner thereof,
LICENSOR or LICENSOR's parent Dolby Laboratories, Inc.

     LICENSEE further agrees that it will not file any application for
registration of the Licensed Trademarks or "Dolby Laboratories" in any country,
region, or under any arrangement or treaty. LICENSEE also agrees that it will
not use nor will it file any application to register in any country, region, or
under any arrangement or treaty any mark, symbol or phrase, in any language,
which is confusingly similar to the Licensed Trademarks or "Dolby Laboratories"

     Section 3.03 - Maintenance of Trademark Rights
     ----------------------------------------------

     The expense of obtaining and maintaining Licensed Trademark registrations
shall be borne by LICENSOR. LICENSOR, as it deems necessary, will advise
LICENSEE of the grant of registration of such trademarks. As LICENSOR deems
necessary, LICENSEE and LICENSOR will comply with applicable laws and practices
of the country of registration, including, without limiting the foregoing, the
marking with notice of registration and the recording of LICENSEE as a

     Section 4.01 - Initial Payment

     LICENSEE shall pay a premium of One Hundred Thirty Dollars ($130.00) on
every Licensed Device used, leased, sold or otherwise disposed of. LICENSEE

to the normal royalties due on Licensed Devices used, leased, sold, or otherwise
disposed of in that quarter, as specified in Section 4.02. The premium is not
subject to adjustment according to the change in the U.S. Consumer Price Index.
When the total number of Licensed Devices which have been used, leased, sold, or
otherwise disposed of by LICENSEE exceeds Three Hundred and Eight (308), the
Initial Payment specified on the title page of this agreement shall be paid in
full and LICENSEE shall stop paying the premium, but shall continue paying

     Subject to the provisions of Section 4.05, LICENSEE shall pay to LICENSOR

disposed of by LICENSEE, except for Licensed Products returned to LICENSEE by
customers of LICENSEE, other than in exchange for an upgraded product, on which
a credit has been allowed by LiCENSEE to said customers. The royalty payable
shall be based on the number of Licensed Products, which are used, sold, leased
or otherwise disposed of by
<PAGE>
 
LICENSEE in successive calendar quarters from the effective date hereof, as
detailed in the schedule given in Appendix E of this Agreement. Subject to the
provisions of Section 4.05, LICENSEE shall pay to LICENSOR royalties on Licensed
Devices manufactured by or for LICENSEE and incorporated in Licensed Products
which are used, sold, leased, or otherwise disposed of by LICENSEE, except for
Licensed Devices incorporated in Licensed Products returned to LICENSEE by
customers of LICENSEE, other than in exchange for an upgraded product, on which
a credit has been allowed by LICENSEE to said customers. The royalty payable
shall be based on the number of Licensed Devices, hereinbefore defined,
contained in Licensed Products, which are used, sold, leased or otherwise
disposed of by LICENSEE in successive calendar quarters from the effective date
hereof, based on the schedule given in Appendix E of this Agreement.

          On the Effective Date of this Agreement, and annually thereafter on
first day of each calendar year, the rate at which the royalties are calculated
shall be adjusted in accordance with the Consumer Price Index. The adjustment
shall be made by multiplying the royalties calculated as specified above by the
ratio between the Consumer Price Index for the last month of the year preceding
the year in which the adjustment takes place and the Consumer Price Index for
the month of December 1993. LICENSOR will, during the first quarter of each
calendar year, or as soon as such information is known, if later, inform
LICENSEE of the adjustment ratio to be applied to royalties due in that year.
The first adjustment to royalty rates shall be made in the quarter commencing
January 1, 1995.

liabilities.

     Each quarterly report shall:

     (a)  state the number of each model type of Licensed Products leased, sold,
or otherwise disposed of by LICENSEE during the calendar quarter with respect to
which the report is due; and

     (4)  LICENSEE shall deliver a final report and payment of royalties to

world. Such a final report shall include a report of all royalties due with
respect to Licensed Products not previously reported to LICENSOR. Such final
report shall be supplemented at the end of the next and subsequent quarters, in
the same manner as provided for during the Life of the Agreement, in the event
that LICENSEE learns of any additional royalties due.

     (5)  LICENSEE shall pay interest to LICENSOR from the due date to the date
payment is made of any overdue royalties or fees, including the Initial Payment,
at the rate of 2% above the prime rate as is in effect from time to time at the
bank identified on the cover page of this Agreement, or another major bank
agreed to by the LICENSOR and LICENSEE in the event that the identified bank

(b) becomes known to LICENSOR from sources other than directly or indirectly
