                         SOUND SOURCE INTERACTIVE, INC.
                           INDEMNIFICATION AGREEMENT


     This Indemnification Agreement ("Agreement") is effective as of April 27,
1998, by and between Sound Source Interactive, Inc., a Delaware corporation (the
"Company"), and Richard Azevedo ("Indemnitee").

     WHEREAS, the Company and Indemnitee recognize the increasing difficulty in
obtaining liability insurance for its officers and directors, the significant
increases in the cost of such insurance and the general reductions in the
coverage of such insurance; and

     WHEREAS, the Company and Indemnitee further recognize the substantial
increase in corporate litigation, subjecting officers and directors to expensive
litigation risks at the same time as the availability and coverage of liability
insurance has been severely limited; and

     WHEREAS, Indemnitee does not regard the current protection available as
adequate under the present circumstances, and the Indemnitee and other officers
and directors of the Company may not be willing to continue to serve in such
capacities without additional protection; and

     WHEREAS, the Company desires to attract and retain the ser  vices of highly
qualified individuals, such as Indemnitee, to serve the Company and, in part, in
order to induce Indemnitee to continue to provide services to the Company,
wishes to provide for the indemnification and advancing of expenses to
Indemnitee to the maximum extent permitted by law.

     NOW, THEREFORE, in consideration for Indemnitee's agreement to continue to
serve the company, the Company and Indemnitee hereby agree as follows:


     1.   Indemnification.
          --------------- 

          (a) Indemnification of Expenses.  The Company shall indemnify
              ---------------------------                              
Indemnitee to the fullest extent permitted by law if Indemnitee was or is or
becomes a party to or witness or other participant in, or is threatened to be
made a party to or witness or other participant in, any threatened, pending or
completed action, suit, proceeding or alternative dispute resolution mechanism,
or any hearing, inquiry or investigation that Indemnitee 
<PAGE>
 
in good faith believes might lead to the institution of any such action, suit,
proceeding or alternative dispute resolution mechanism, whether civil, criminal,
administrative, investigative or other (hereinafter a "Claim") by reason of (or
arising in part out of) any event or occurrence related to the fact that
Indemnitee is or was a director, officer, employee or agent of the Company, or
any subsidiary of the Company, or is or was serving at the request of the
Company as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise, or by reason of any
action or inaction on the part of Indemnitee while serving in such capacity
(hereinafter an "Indemnifiable Event") against any and all expenses (including
attorneys' fees and all other costs, expenses and obligations incurred in
connection with investigating, defending, being a witness in or participating in
(including an appeal), or preparing to defend, be a witness in or participate
in, any such action, suit, proceeding, alternative dispute resolution mechanism,
hearing, inquiry or investigation), judgments, fines, penalties and amounts paid
in settlement (if such settlement is; approved in advance by the Company, which
approval shall not be unreasonably withheld) of such Claim and any federal,
state, local or foreign taxes imposed on the Indemnitee as a result of the
actual or deemed receipt of any payments under this Agreement (collectively,
hereinafter ("Expenses"), including all interest, assessments and other charges
paid or payable in connection with or in respect of such Expenses. Such payment
of Expenses shall be made by the Company as soon as practicable but in any event
no later than five days after written demand by Indemnitee therefor is presented
to the Company.

          (b) Reviewing Party.  Notwithstanding the foregoing, (i) the
              ---------------                                         
obligation of the Company under Section 1(a) shall be subject to the condition
that the Reviewing Party (as described in Section 10(e) hereof) shall not have
determined (in a written opinion in any case in which the Independent Legal
Counsel referred to in section 1(c) hereof is involved) that Indemnitee would
not be permitted to be indemnified under applicable law, and (ii) the obligation
of the Company to make an advance payment of Expenses to Indemnitee pursuant to
Section 2(a) (an "Expense Advance") shall be subject to the condition that, if,
when and to the extent that the Reviewing Party shall have determined that
Indemnitee would not be permitted to be so indemnified under applicable law, the
Company shall be entitled to be reimbursed by Indemnitee (who hereby agrees to
reimburse the Company) for all such amounts theretofore paid; provided, however,
that if Indemnitee has commenced or thereafter commences legal proceedings in a
court of competent jurisdiction to secure a determination that Indemnitee should
be indemnified under applicable law, any determination made by the Reviewing
Party that Indemnitee would not be permitted to be indemnified under applicable
law shall not be binding and Indemnitee shall not be required to reimburse the
Company for any Expense Advance until a 
                                      
                                       2
<PAGE>
 
final judicial determination is made with respect thereto (as to which all
rights of appeal therefrom have been exhausted or lapsed). Indemnitee's
obligation to reimburse the Company for any Expense Advance shall be unsecured
and no interest shall be charged thereon. If there has not been a Change in
Control (as defined in Section 10(c) hereof), the Reviewing Party shall be
selected by the Board of Directors, and if there has been such a Change in
Control (other than a Change in Control which has been approved by a majority of
the Company's Board of Directors who were directors immediately prior to such
Change in Control), the Reviewing Party shall be the Independent Legal Counsel
referred to in Section 1(c) hereof. If there has been no determination by the
Reviewing Party or if the Reviewing Party determines that Indemnitee
substantively would not be permitted to be indemnified in whole or in part under
applicable law, Indemnitee shall have the right to commence litigation seeking
an initial determination by the court or challenging any such determination by
the Reviewing Party or any aspect thereof, including the legal or factual bases
therefor, and the Company hereby consents to service of process and to appear in
any such proceeding. Any determination by the Reviewing Party otherwise shall be
conclusive and binding on the Company and Indemnitee.

          (c) Change in Control.  The Company agrees that if there is a Change
              -----------------                                               
in Control of the Company (other than a Change in Control which has been
approved by a majority of the Company's Board of Directors who were directors
immediately prior to such Change in Control) then with respect to all matters
thereafter arising concerning the rights of Indemnitee to payments of Expenses
and Expense Advances under this Agreement or any other agreement or under the
Company's Certificate of Incorporation or Bylaws as now or hereafter in effect,
Independent Legal Counsel, (as defined in Section 10(d) hereof) shall be
selected by Indemnitee and approved by the Company (which approval shall not be
unreasonably withheld). Such counsel, among other things, shall render its
written opinion to the Company and Indemnitee as to whether and to what extent
Indemnitee would be permitted to be indemnified under applicable law and the
Company agrees to abide by such opinion.  The Company agrees to pay the
reasonable fees of the Independent Legal Counsel referred to above and to
indemnify fully such counsel against any and all expenses (including attorneys'
fees), claims, liabilities and damages arising out of or relating to this
Agreement or its engagement pursuant hereto.

          (d) Mandatory Payment of Expenses.  Notwithstanding any other
              -----------------------------                            
provision of this Agreement other than Section 9 hereof, to the extent that
Indemnitee has been successful on the merits or otherwise, including, without
limitation, the dismissal of an action without prejudice, in defense of any
action, suit, proceeding, inquiry or investigation referred to in Section 1(a)

                                       3
<PAGE>
 
hereof or in the defense of any claim, issue or matter therein, Indemnitee shall
be indemnified against all Expenses incurred by Indemnitee in connection
therewith.


     2.   Expenses; Indemnification Procedures.
          ------------------------------------ 

          (a) Advancement of Expenses.  The Company shall advance all expenses
              -----------------------                                         
incurred by Indemnitee.  The advances to be made hereunder shall be paid by the
Company to Indemnitee as soon as practicable but in any event no later than five
days after written demand by Indemnitee therefor to the Company.

          (b) Notice/Cooperation by Indemnitee.  Indemnitee shall, as a
              --------------------------------                         
condition precedent to Indemnitee's right to be indemnified under this
Agreement, give the Company notice in writing as soon as practicable of any
Claim made against Indemnitee for which indemnification will or could be sought
under this Agreement. Notice to the Company shall be directed to the Chief
Executive Officer of the Company at the address shown on the signature page of
this Agreement (or such other address as the Company shall designate in writing
to Indemnitee).  In addition, Indemnitee shall give the Company such information
and cooperation as it may reasonably require and as shall be within Indemnitee's
power.

          (c)  No Presumptions; Burden of Proof.  For purposes of this
               --------------------------------                       
Agreement, the termination of any Claim by Judgment, order, settlement (whether
with or without court approval) or conviction, or upon a plea of nolo
                                                                 ----
contendere, or its equivalent, shall not create a presumption that indemnitee
----------
did not meet any particular standard of conduct or have any particular belief or
that a court has determined that indemnification is not permitted by applicable
law.  In addition, neither the failure of the Reviewing Party to have made a
determination as to whether Indemnitee has not any particular standard of
conduct or had any particular belief, nor an actual determination by the
Reviewing Party that Indemnitee has not met such standard of conduct or did not
have such belief, prior to the commencement of legal proceedings by Indemnitee
to secure a judicial determination that Indemnitee should be indemnified under
applicable law, shall be a defense to Indemnitee's claim or create a presumption
that Indemnitee has not met any particular standard of conduct or did not have
any particular belief.  In connection with any determination by the Reviewing
Party or otherwise as to whether the Indemnitee is entitled to be indemnified
hereunder, the burden of proof shall be on the Company to establish that
Indemnitee is not so entitled.

          (d) Notice to Insurers.  If, at the time of the receipt by the
              ------------------                                        
Company, of a notice of a Claim pursuant to Section 2(b) hereof, the Company has
liability insurance in effect which may 

                                       4
<PAGE>
 
cover such claim, the Company shall give prompt notice of the commencement of
such Claim to the insurers in accordance with the procedures set forth in the
respective policies. The Company shall thereafter take all necessary or
desirable action to cause such insurers to pay, on behalf of the Indemnitee, all
amounts payable as a result of such action, suit, proceeding, inquiry or
investigation in accordance with the terms of such policies.

          (e) Selection of Counsel. In the event the Company shall be obligated
              --------------------                                             
hereunder to pay the Expenses of any Claim, the Company, if appropriate, shall
be entitled to assume the defense of such Claim with counsel approved by
Indemnitee, upon the delivery to Indemnitee of written notice of its election so
to do.  After delivery of such notice, approval of such counsel by Indemnitee
and the retention of such counsel by the Company, the Company will not be liable
to Indemnitee under this Agreement for any fees of counsel subsequently incurred
by Indemnitee with respect to the same Claim; provided that, (i) Indemnitee
shall have the right to employ Indemnitee's counsel in any such Claim at
Indemnitee's expense and (ii) if (A) the employment of counsel by Indemnitee has
been previously authorized by the Company, (B) Indemnitee shall have reasonably
concluded that there may be a conflict of interest between the Company and
Indemnitee in the conduct of any such defense, or (C) the Company shall not
continue to retain such counsel to defend such Claim, then the reasonable fees
and expenses of Indemnitee's counsel shall be at the expense of the Company.


     3.   Additional Indemnification Rights; Nonexclusivity.
          ------------------------------------------------- 

          (a) Scope.  Notwithstanding any other provision of this Agreement, the
              -----                                                             
Company hereby agrees to indemnify the Indemnitee to the fullest extent
permitted by law, notwithstanding that such indemnification is not specifically
authorized by the other provisions of this Agreement, the Company's Certificate
of Incorporation, the Company's Bylaws or by statute.  In the event of any
change after the date of this Agreement in any applicable law, statute or rule
which expands the right of a Delaware corporation to indemnify a member of its
Board of Directors or an officer, such changes shall be, ipso facto, within the
                                                         ---- -----            
purview of an Indemnitee's rights, and the Company's obligations, under this
Agreement.  In the event of any change in any applicable law, statute or rule
which narrows the right of a Delaware corporation to indemnify a member of its
Board of Directors or an officer, such changes, to the extent not otherwise
required by such law, statute or rule to be applied to this Agreement, shall
have no effect on this Agreement or the parties' rights and obligations
hereunder.

                                       5
<PAGE>
 
          (b) Nonexclusivity.  The indemnification provided by this Agreement
              --------------                                                 
shall not be deemed exclusive of any rights to which an Indemnitee may be
entitled under the Company's Certificate of Incorporation, the Company's Bylaws,
any agreement, any vote of stockholders or disinterested Directors, the General
Corporation Law of the State of Delaware, or otherwise, both as to action in
Indemnitee's official capacity and as to action in another capacity while
holding such office.  The indemnification provided under this Agreement shall
continue as to Indemnitee for any action taken or not taken while serving in an
indemnified capacity even though Indemnitee may have ceased to serve in such
capacity at the time of any action, suit or other covered proceeding.


     4.   No Duplication of Payments.  The Company shall not be liable under
          --------------------------                                        
this Agreement to make any payment in connection with any Claim made against
Indemnitee to the extent Indemnitee has otherwise actually received payment
(under any insurance policy, Certificate of Incorporation, Bylaw or otherwise)
of the amounts otherwise indemnifiable hereunder.


     5.   Partial Indemnification.  If Indemnitee is entitled under any
          -----------------------                                      
provision of this Agreement to indemnification by the Company for some or a
portion of Expenses incurred by him in connection with any Claim, but not,
however, for the total amount thereof, the Company shall nevertheless indemnify
Indemnitee for the portion of such Expenses to which Indemnitee is entitled.


     6.   Mutual Acknowledgment.  Both the Company and Indemnitee acknowledge
          ---------------------                                              
that in certain instances, Federal law or applicable public policy may override
Delaware law and prohibit the Company from indemnifying its directors and
officers under this Agreement or otherwise.  For example, the Company and
Indemnitee acknowledge that the Securities and Exchange Commission has taken the
position that indemnification is not permissible for liabilities arising under
certain federal securities laws, and federal legislation pro  hibits
indemnification for certain ERISA violations.  Indemnitee understands and
acknowledges that the Company has undertaken or may be required in the future to
undertake with the Securities and Exchange Commission to submit the question of
indemnification to a court in certain circumstances for a determination of the
Company's right under public policy to indemnify Indemnitee.


     7.   Officer and Director Liability.  The Company shall, from time to time,
          ------------------------------                                        
make the good faith determination whether or not it is practicable for the
Company to obtain and maintain a policy or policies of insurance with reputable
insurance companies providing 

                                       6
<PAGE>
 
the officers and directors of the Company with coverage for losses from wrongful
acts, or to ensure the Company's performance of its indemnification obligations
under this Agreement. Among other considerations, the Company will weigh the
costs of obtaining such insurance coverage against the protection afforded by
such coverage. In all policies of director and officer liability insurance,
Indemnitee shall be named as an insured in such a manner as to provide
Indemnitee the same rights and benefits as are accorded to the most favorably
insured of the Company's directors, if the Indemnitee is a director; or of the
Company's officers, if the Indemnitee is not a director of the Company but is an
officer; or of the Company's key employees, if Indemnitee is not an officer or
director but is a key employee. Notwithstanding the foregoing, the Company shall
have no obligation to obtain or maintain such insurance if the Company
determines in good faith that such insurance is not reasonably available, the
premium costs for such insurance are disproportionate to the amount of coverage
provided, the coverage provided by such insurance is limited by exclusions so as
to provide an insufficient benefit, or Indemnitee is covered by a similar
insurance maintained by a subsidiary or parent of the Company.


     8.   Exceptions.  Any other provision herein to the contrary
          ----------                                             
notwithstanding, the Company shall not be obligated pursuant to the terms of
this Agreement:

          (a) Excluded Action or Omissions.  To indemnify Indemnitee for acts,
              ----------------------------                                    
omissions or transactions from which Indemnitee may not be relieved of liability
under applicable law;

          (b) Claims Initiated by Indemnitee.  To indemnify or advance expenses
              ------------------------------                                   
to Indemnitee with respect to Claims initiated or brought voluntarily by
Indemnitee and not by way of defense, except (i) with respect to actions or
proceedings brought to establish or enforce a right to indemnification under
this Agreement or any other agreement or insurance policy or under the Company's
Certificate of Incorporation or Bylaws now or hereafter in effect relating to
Claims for Indemnifiable Events, (ii) in specific cases if the Board of
Directors has approved the initiation or bringing of such Claim, or (iii) as
otherwise required under Section 145 of the Delaware General Corporation Law,
regardless of whether Indemnitee ultimately is determined to be entitled to such
indemnification, advance expense payment or insurance recovery, as the case may
be;

          (c) Lack of Good Faith. To indemnify Indemnitee for any expenses
              ------------------                                          
incurred by the Indemnitee with respect to any proceeding instituted by
Indemnitee to enforce or interpret this Agreement, if a court of intent
jurisdiction determines that each of the material 

                                       7
<PAGE>
 
assertions made by the Indemnitee in such proceeding was not made in good faith
or was frivolous;

          (d) Insured Claims.  To indemnify indemnitee for expenses or
              --------------                                          
liabilities of any type whatsoever (including, but not limited to, Judgments,
fines ERISA excise taxes or Penalties, and amounts paid in settlement) which
have been paid directly to Indemnitee by an insurance carrier under a policy of
officers' and directors' liability insurance maintained by the Company or any
parent or subsidiary of the Company; or

          (e) Claims Under Section 16(b).  To indemnify Indemnitee for expenses
              --------------------------                                       
or the payment of profits arising from the purchase and sale by Indemnitee of
securities in violation of Section 16(b) of the Securities Exchange Act of 1934,
as amended, or any similar successor statute.


     9.   Period of Limitation.  No legal action shall be brought and no cause
          --------------------                                                
of action shall be asserted by or in the right of the Company against
Indemnitee, Indemnitee's estate, spouse, heirs, executors or personal or legal
representatives after the expiration of two years from the date of accrual of
such cause of action, and any claim or cause of action of the Company shall be
extinguished and deemed released unless asserted by the timely filing of a legal
action within such two-year period; provided, that if any shorter period of
limitations is otherwise applicable to any such cause of action, such shorter
period shall govern.


     10.  Construction of Certain Phrases.
          ------------------------------- 

          (a)  For purposes of this Agreement, references to the "Company" shall
include, in addition to the resulting corporation, any constituent corporation
(including any constituent of a constituent) absorbed in a consolidation or
merger which, if its separate existence had continued, would have had power and
authority to indemnify its officers and directors, so that if Indemnitee is or
was an officer or director of such constituent corporation, or is or was serving
at the request of such constituent corporation as a director, officer, employee
or agent of another corporation, partnership, joint venture, employee benefit
plan, trust or other enterprise, Indemnitee shall stand in the same position
under the provisions of this Agreement with respect to the resulting or
surviving corporation as Indemnitee would have with respect to such constituent
corporation if its separate existence had continued.

                                       8
<PAGE>
 
          (b) For purposes of this Agreement, references to "other enterprises"

and references to "serving at the request of the Company" shall include any
service as an officer or director of the Company which imposes duties on, or
involves services by, such officer or director with respect to an employee
benefit plan, its participants or its beneficiaries and if Indemnitee acted in
good faith and in a manner Indemnitee reasonably believed to be in the interest
of the participants and beneficiaries of an employee benefit plan, Indemnitee
shall be deemed to have acted in a manner "not opposed to the best interests of
the Company" as referred to in this Agreement.

          (c) For purposes of this Agreement a "Change in Control" shall be
deemed to have occurred if (i) any "person" (as such term is used in Sections
13(d) and 14(d) of the Securities Exchange Act of 1934, as amended), other than
a trustee or other fiduciary hold  ing securities under an employee benefit plan
of the Company or a corporation owned directly or indirectly by the stockholders
of the company in substantially the same proportions as their ownership of stock
of the Company, (A) who is or becomes the beneficial owner, directly or

combined voting power of the Company's then outstanding Voting Securities,
increases his beneficial ownership of such securities by 5% or more over the
percentage so owned by such person, or (B) becomes the "beneficial owner" (as
defined in Rule 13d-3 under said Act), directly or indirectly, of securities of
the Company representing more than 20% of the total voting power represented by
the Company's then outstanding Voting Securities, (ii) during any period of two
consecutive years, individuals who at the beginning of such period constitute
the Board of Directors of the Company and any new director whose election by the
Board of Directors or nomination for election by the Company's stockholders was
approved by a vote of at least two-thirds of the directors then still in office
who either were directors at the beginning of the period or whose election or
nomination or election was previously so approved, cease for any reason to
constitute a majority thereof, or (iii) the stockholders of the Company approve
a merger or consolidation of the Company with any other corporation other than a
merger or consolidation which would result in the Voting Securities of the
Company outstanding immediately prior thereto continuing to represent (either by
remaining outstanding or by being converted into Voting Securities of the
surviving entity) at least 80% of the total voting power represented by the
Voting Securities of the company or such surviving entity outstanding
immediately after such merger or consolidation, or the stockholders of the
company approve a plan of complete liquidation of the Company or an agreement
for the sale or disposition by the Company
