                                      -3-


     4.  Administration of the Plan.
         --------------------------

         (a)   Administrator.  The Plan shall be administered by the Board or a
               -------------
Committee appointed by the Board, which Committee shall be constituted to comply
with Applicable Laws.

         (b)   Powers of the Administrator.  Subject to the provisions of the
               ---------------------------
Plan and, in the case of a Committee, the specific duties delegated by the Board
to such Committee, and subject to the approval of any relevant authorities, the
Administrator shall have the authority in its discretion:

               (i)    to determine the Fair Market Value;

               (ii)   to select the Service Providers to whom Options and Stock
Purchase Rights may from time to time be granted hereunder;

               (iii)  to determine the number of Shares to be covered by each
such award granted hereunder;

               (iv)   to approve forms of agreement for use under the Plan;

               (v)    to determine the terms and conditions of any Option or
Stock Purchase Right granted hereunder. Such terms and conditions include, but
are not limited to, the exercise price, the time or times when Options or Stock
Purchase Rights may be exercised (which may be based on performance criteria),
any vesting acceleration or waiver of forfeiture restrictions, and any
restriction or limitation regarding any Option or Stock Purchase Right or the
Common Stock relating thereto, based in each case on such factors as the
Administrator, in its sole discretion, shall determine;

               (vi)   to determine whether and under what circumstances an
Option may be settled in cash under subsection 9(e) instead of Common Stock;

               (vii)  to reduce the exercise price of any Option to the then
current Fair Market Value if the Fair Market Value of the Common Stock covered
by such Option has declined since the date the Option was granted;

               (viii) to initiate an Option Exchange Program;

               (ix)   to prescribe, amend and rescind rules and regulations
relating to the Plan, including rules and regulations relating to sub-plans
established for the purpose of qualifying for preferred tax treatment under
foreign tax laws;

               (x)    to allow Optionees to satisfy withholding tax obligations
by electing to have the Company withhold from the Shares to be issued upon
exercise of an Option or Stock Purchase Right that number of Shares having a
Fair Market Value equal to the amount required to be withheld. The Fair Market
Value of the Shares to be withheld shall be determined on the date that the
amount of tax to be withheld is to be determined. All elections by Optionees to
have Shares

                                      -4-


withheld for this purpose shall be made in such form and under such conditions
as the Administrator may deem necessary or advisable; and

               (xi)   to construe and interpret the terms of the Plan and awards
granted pursuant to the Plan.

          (c)  Effect of Administrator's Decision. All decisions, determinations
               ----------------------------------
and interpretations of the Administrator shall be final and binding on all
Optionees.

     5.   Eligibility.
          -----------

          (a)  Nonstatutory Stock Options and Stock Purchase Rights may be
granted to Service Providers. Incentive Stock Options may be granted only to
Employees.

          (b)  Each Option shall be designated in the Option Agreement as either
an Incentive Stock Option or a Nonstatutory Stock Option. However,
notwithstanding such designation, to the extent that the aggregate Fair Market
Value of the Shares with respect to which Incentive Stock Options are
exercisable for the first time by the Optionee during any calendar year (under
all plans of the Company and any Parent or Subsidiary) exceeds $100,000, such
Options shall be treated as Nonstatutory Stock Options. For purposes of this
Section 5(b), Incentive Stock Options shall be taken into account in the order
in which they were granted. The Fair Market Value of the Shares shall be
determined as of the time the Option with respect to such Shares is granted.

          (c)  Neither the Plan nor any Option or Stock Purchase Right shall
confer upon any Optionee any right with respect to continuing the Optionee's
relationship as a Service Provider with the Company, nor shall it interfere in
any way with his or her right or the Company's right to terminate such
relationship at any time, with or without cause.

     6.   Term of Plan. The Plan shall become effective upon its adoption by the
          ------------
Board. It shall continue in effect for a term of ten (10) years unless sooner
terminated under Section 14 of the Plan.

     7.   Term of Option.  The term of each Option shall be stated in the Option
          --------------
Agreement; provided, however, that the term shall be no more than ten (10) years
from the date of grant thereof.  In the case of an Incentive Stock Option
granted to an Optionee who, at the time the Option is granted, owns stock
representing more than ten percent (10%) of the voting power of all classes of
stock of the Company or any Parent or Subsidiary, the term of the Option shall
be five (5) years from the date of grant or such shorter term as may be provided
in the Option Agreement.

                                      -5-


     8.   Option Exercise Price and Consideration.
          ---------------------------------------

          (a)  The per share exercise price for the Shares to be issued upon
exercise of an Option shall be such price as is determined by the Administrator,
but shall be subject to the following:

               (i)    In the case of an Incentive Stock Option

                      (A)  granted to an Employee who, at the time of grant of
such Option, owns stock representing more than ten percent (10%) of the voting
power of all classes of stock of the Company or any Parent or Subsidiary, the
exercise price shall be no less than 110% of the Fair Market Value per Share on
the date of grant.

                      (B)  granted to any other Employee, the per Share exercise
price shall be no less than 100% of the Fair Market Value per Share on the date
of grant.

               (ii)   In the case of a Nonstatutory Stock Option

                      (A)  granted to a Service Provider who, at the time of
grant of such Option, owns stock representing more than ten percent (10%) of the
voting power of all classes of stock of the Company or any Parent or Subsidiary,
the exercise price shall be no less than 110% of the Fair Market Value per Share
on the date of grant.

                      (B)  granted to any other Service Provider, the per Share
exercise price shall be no less than 85% of the Fair Market Value per Share on
the date of grant.

               (iii)  Notwithstanding the foregoing, Options may be granted with
a per Share exercise price other than as required above pursuant to a merger or
other corporate transaction.

          (b)  The consideration to be paid for the Shares to be issued upon
exercise of an Option, including the method of payment, shall be determined by
the Administrator (and, in the case of an Incentive Stock Option, shall be
determined at the time of grant). Such consideration may consist of (1) cash,
(2) check, (3) promissory note, (4) other Shares which (x) in the case of Shares
acquired upon exercise of an Option, have been owned by the Optionee for more
than six months on the date of surrender, and (y) have a Fair Market Value on
the date of surrender equal to the aggregate exercise price of the Shares as to
which such Option shall be exercised, (5) consideration received by the Company
under a cashless exercise program implemented by the Company in connection with
the Plan, or (6) any combination of the foregoing methods of payment. In making
its determination as to the type of consideration to accept, the Administrator
shall consider if acceptance of such consideration may be reasonably expected to
benefit the Company.

                                      -6-


     9.   Exercise of Option.
          ------------------

          (a) Procedure for Exercise; Rights as a Stockholder. Any Option
              -----------------------------------------------
granted hereunder shall be exercisable according to the terms hereof at such
times and under such conditions as determined by the Administrator and set forth
in the Option Agreement.  Except in the case of Options granted to Officers,
Directors and Consultants, Options shall become exercisable at a rate of no less
than 20% per year over five (5) years from the date the Options are granted.
Unless the Administrator provides otherwise, vesting of Options granted
hereunder shall be tolled during any unpaid leave of absence.  An Option may not
be exercised for a fraction of a Share.

          An Option shall be deemed exercised when the Company receives: (i)
written or electronic notice of exercise (in accordance with the Option
Agreement) from the person entitled to exercise the Option, and (ii) full
payment for the Shares with respect to which the Option is exercised.  Full
payment may consist of any consideration and method of payment authorized by the
Administrator and permitted by the Option Agreement and the Plan.  Shares issued
upon exercise of an Option shall be issued in the name of the Optionee or, if
requested by the Optionee, in the name of the Optionee and his or her spouse.
Until the Shares are issued (as evidenced by the appropriate entry on the books
of the Company or of a duly authorized transfer agent of the Company), no right
to vote or receive dividends or any other rights as a stockholder shall exist
with respect to the Shares, notwithstanding the exercise of the Option.  The
Company shall issue (or cause to be issued) such Shares promptly after the
Option is exercised.  No adjustment will be made for a dividend or other right
for which the record date is prior to the date the Shares are issued, except as
provided in Section 12 of the Plan.

          Exercise of an Option in any manner shall result in a decrease in the
number of Shares thereafter available, both for purposes of the Plan and for
sale under the Option, by the number of Shares as to which the Option is
exercised.

          (b) Termination of Relationship as a Service Provider.  If an Optionee
              -------------------------------------------------
ceases to be a Service Provider, such Optionee may exercise his or her Option
within such period of time as is specified in the Option Agreement (of at least
thirty (30) days) to the extent that the Option is vested on the date of
termination (but in no event later than the expiration of the term of the Option
as set forth in the Option Agreement).  In the absence of a specified time in
the Option Agreement, the Option shall remain exercisable for three (3) months
following the Optionee's termination.  If, on the date of termination, the
Optionee is not vested as to his or her entire Option, the Shares covered by the
unvested portion of the Option shall revert to the Plan.  If, after termination,
the Optionee does not exercise his or her Option within the time specified by
the Administrator, the Option shall terminate, and the Shares covered by such
Option shall revert to the Plan.

          (c) Disability of Optionee.  If an Optionee ceases to be a Service
              ----------------------
Provider as a result of the Optionee's Disability, the Optionee may exercise his
or her Option within such period of time as is specified in the Option Agreement
(of at least six (6) months) to the extent the Option is vested on the date of
termination (but in no event later than the expiration of the term of such
Option as set forth in the Option Agreement).  In the absence of a specified
time in the Option Agreement,

                                      -7-


the Option shall remain exercisable for twelve (12) months following the
Optionee's termination. If, on the date of termination, the Optionee is not
vested as to his or her entire Option, the Shares covered by the unvested
portion of the Option shall revert to the Plan. If, after termination, the
Optionee does not exercise his or her Option within the time specified herein,
the Option shall terminate, and the Shares covered by such Option shall revert
to the Plan.

          (d) Death of Optionee.  If an Optionee dies while a Service Provider,
              -----------------
the Option may be exercised within such period of time as is specified in the
Option Agreement (of at least six (6) months) to the extent that the Option is
vested on the date of death (but in no event later than the expiration of the
term of such Option as set forth in the Option Agreement) by the Optionee's
estate or by a person who acquires the right to exercise the Option by bequest
or inheritance.  In the absence of a specified time in the Option Agreement, the
Option shall remain exercisable for twelve (12) months following the Optionee's
termination.  If, at the time of death, the Optionee is not vested as to the
entire Option, the Shares covered by the unvested portion of the Option shall
immediately revert to the Plan.  If the Option is not so exercised within the
time specified herein, the Option shall terminate, and the Shares covered by
such Option shall revert to the Plan.

          (e) Buyout Provisions.  The Administrator may at any time offer to buy
              -----------------
out for a payment in cash or Shares, an Option previously granted, based on such
terms and conditions as the Administrator shall establish and communicate to the
Optionee at the time that such offer is made.

     10.  Non-Transferability of Options and Stock Purchase Rights.  The Options
          --------------------------------------------------------
and Stock Purchase Rights may not be sold, pledged, assigned, hypothecated,
transferred, or disposed of in any manner other than by will or by the laws of
descent or distribution and may be exercised, during the lifetime of the
Optionee, only by the Optionee.

     11.  Stock Purchase Rights.
          ---------------------

          (a) Rights to Purchase.  Stock Purchase Rights may be issued either
              ------------------
alone, in addition to, or in tandem with other awards granted under the Plan
and/or cash awards made outside of the Plan.  After the Administrator determines
that it will offer Stock Purchase Rights under the Plan, it shall advise the
offeree in writing or electronically of the terms, conditions and restrictions
related to the offer, including the number of Shares that such person shall be
entitled to purchase, the price to be paid, and the time within which such
person must accept such offer.  The terms of the offer shall comply in all
respects with Section 260.140.42 of Title 10 of the California Code of
Regulations.  The offer shall be accepted by execution of a Restricted Stock
purchase agreement in the form determined by the Administrator.

          (b) Repurchase Option.  Unless the Administrator determines otherwise,
              -----------------
the Restricted Stock purchase agreement shall grant the Company a repurchase
option exercisable upon the voluntary or involuntary termination of the
purchaser's service with the Company for any reason (including death or
disability).  The purchase price for Shares repurchased pursuant to the
Restricted Stock purchase agreement shall be the original price paid by the
purchaser and may be paid by cancellation of any indebtedness of the purchaser
to the Company.  The repurchase option shall lapse

                                      -8-


at such rate as the Administrator may determine. Except with respect to Shares
purchased by Officers, Directors and Consultants, the repurchase option shall in
no case lapse at a rate of less than 20% per year over five (5) years from the
date of purchase.

          (c) Other Provisions.  The Restricted Stock purchase agreement shall
              ----------------
contain such other terms, provisions and conditions not inconsistent with the
Plan as may be determined by the Administrator in its sole discretion.

          (d) Rights as a Stockholder.  Once the Stock Purchase Right is
              -----------------------
exercised, the purchaser shall have rights equivalent to those of a stockholder
and shall be a stockholder when his or her purchase is entered upon the records
of the duly authorized transfer agent of the Company.  No adjustment shall be
made for a dividend or other right for which the record date is prior to the
date the Stock Purchase Right is exercised, except as provided in Section 12 of
the Plan.

     12.  Adjustments Upon Changes in Capitalization, Merger or Asset Sale.
          ----------------------------------------------------------------

          (a) Changes in Capitalization.  Subject to any required action by the
              -------------------------
stockholders of the Company, the number of shares of Common Stock covered by
each outstanding Option or Stock Purchase Right, and the number of shares of
Common Stock which have been authorized for issuance under the Plan but as to
which no Options or Stock Purchase Rights have yet been granted or which have
been returned to the Plan upon cancellation or expiration of an Option or Stock
Purchase Right, as well as the price per share of Common Stock covered by each
such outstanding Option or Stock Purchase Right, shall be proportionately
adjusted for any increase or decrease in the number of issued shares of Common
Stock resulting from a stock split, reverse stock split, stock dividend,
combination or reclassification of the Common Stock, or any other increase or
decrease in the number of issued shares of Common Stock effected without receipt
of consideration by the Company.  The conversion of any convertible securities
of the Company shall not be deemed to have been "effected without receipt of
consideration."  Such adjustment shall be made by the Board, whose determination
in that respect shall be final, binding and conclusive.  Except as expressly
provided herein, no issuance by the Company of shares of stock of any class, or
securities convertible into shares of stock of any class, shall affect, and no
adjustment by reason thereof shall be made with respect to, the number or price
of shares of Common Stock subject to an Option or Stock Purchase Right.

          (b) Dissolution or Liquidation.  In the event of the proposed
              --------------------------
dissolution or liquidation of the Company, the Administrator shall notify each
Optionee as soon as practicable prior to the effective date of such proposed
transaction.  The Administrator in its discretion may provide for an Optionee to
have the right to exercise his or her Option or Stock Purchase Right until
fifteen (15) days prior to such transaction as to all of the Optioned Stock
covered thereby, including Shares as to which the Option or Stock Purchase Right
would not otherwise be exercisable.  In addition, the Administrator may provide
that any Company repurchase option applicable to any Shares purchased upon
exercise of an Option or Stock Purchase Right shall lapse as to all such Shares,
provided the proposed dissolution or liquidation takes place at the time and in
the manner contemplated.  To the

                                      -9-


extent it has not been previously exercised, an Option or Stock Purchase Right
will terminate immediately prior to the consummation of such proposed action.

          (c) Merger or Asset Sale.  In the event of a merger of the Company
              --------------------
with or into another corporation, or the sale of substantially all of the assets
of the Company, each outstanding Option and Stock Purchase Right shall be
assumed or an equivalent option or right substituted by the successor
corporation or a Parent or Subsidiary of the successor corporation. In the event
that the successor corporation refuses to assume or substitute for the Option or
Stock Purchase Right, the Optionee shall fully vest in and have the right to
exercise the Option or Stock Purchase Right as to all of the Optioned Stock,
including Shares as to which it would not otherwise be vested or exercisable. If
an Option or Stock Purchase Right becomes fully vested and exercisable in lieu
of assumption or substitution in the event of a merger or sale of assets, the
Administrator shall notify the Optionee in writing or electronically that the
Option or Stock Purchase Right shall be fully exercisable for a period of
fifteen (15) days from the date of such notice, and the Option or Stock Purchase
Right shall terminate upon the expiration of such period. For the purposes of
this paragraph, the Option or Stock Purchase Right shall be considered assumed
if, following the merger or sale of assets, the option or right confers the
right to purchase or receive, for each Share of Optioned Stock subject to the
Option or Stock Purchase Right immediately prior to the merger or sale of
assets, the consideration (whether stock, cash, or other securities or property)
received in the merger or sale of assets by holders of Common Stock for each
Share held on the effective date of the transaction (and if holders were offered
a choice of consideration, the type of consideration chosen by the holders of a
majority of the outstanding Shares); provided, however, that if such
consideration received in the merger or sale of assets is not solely common
stock of the successor corporation or its Parent, the Administrator may, with
the consent of the successor corporation, provide for the consideration to be
received upon the exercise of the Option or Stock Purchase Right, for each Share
of Optioned Stock subject to the Option or Stock Purchase Right, to be solely
common stock of the successor corporation or its Parent equal in fair market
value to the per share consideration received by holders of Common Stock in the
merger or sale of assets.

     13.  Time of Granting Options and Stock Purchase Rights.  The date of grant
          --------------------------------------------------
of an Option or Stock Purchase Right shall, for all purposes, be the date on
which the Administrator makes the determination granting such Option or Stock
Purchase Right, or such other date as is determined by the Administrator.
Notice of the determination shall be given to each Service Provider to whom an
Option or Stock Purchase Right is so granted within a reasonable time after the
date of such grant.

     14.  Amendment and Termination of the Plan.
          -------------------------------------

          (a) Amendment and Termination.  The Board may at any time amend,
              -------------------------
alter, suspend or terminate the Plan.

          (b) Stockholder Approval.  The Board shall obtain stockholder approval
              --------------------
of any Plan amendment to the extent necessary and desirable to comply with
Applicable Laws.

                                      -10-


          (c) Effect of Amendment or Termination.  No amendment, alteration,
              ----------------------------------
suspension or termination of the Plan shall impair the rights of any Optionee,
unless mutually agreed otherwise between the Optionee and the Administrator,
which agreement must be in writing and signed by the Optionee and the Company.
Termination of the Plan shall not affect the Administrator's ability to exercise
the powers granted to it hereunder with respect to Options granted under the
Plan prior to the date of such termination.

     15.  Conditions Upon Issuance of Shares.
          ----------------------------------

          (a) Legal Compliance.  Shares shall not be issued pursuant to the
              ----------------
exercise of an Option unless the exercise of such Option and the issuance and
delivery of such Shares shall comply with Applicable Laws and shall be further
subject to the approval of counsel for the Company with respect to such
compliance.

          (b) Investment Representations.  As a condition to the exercise of an
              --------------------------
Option, the Administrator may require the person exercising such Option to
represent and warrant at the time of any such exercise that the Shares are being
purchased only for investment and without any present intention to sell or
distribute such Shares if, in the opinion of counsel for the Company, such a
representation is required.

     16.  Inability to Obtain Authority.  The inability of the Company to obtain
          -----------------------------
authority from any regulatory body having jurisdiction, which authority is
deemed by the Company's counsel to be necessary to the lawful issuance and sale
of any Shares hereunder, shall relieve the Company of any liability in respect
of the failure to issue or sell such Shares as to which such requisite authority
shall not have been obtained.

     17.  Reservation of Shares.  The Company, during the term of this Plan,
          ---------------------
shall at all times reserve and keep available such number of Shares as shall be
sufficient to satisfy the requirements of the Plan.

     18.  Stockholder Approval.  The Plan shall be subject to approval by the
          --------------------
stockholders of the Company within twelve (12) months after the date the Plan is
adopted.  Such stockholder approval shall be obtained in the degree and manner
required under Applicable Laws.

     19.  Information to Optionees and Purchasers.  The Company shall provide to
          ---------------------------------------
each Optionee and to each individual who acquires Shares pursuant to the Plan,
not less frequently than annually during the period such Optionee or purchaser
has one or more Options or Stock Purchase Rights outstanding, and, in the case
of an individual who acquires Shares pursuant to the Plan, during the period
such individual owns such Shares, copies of annual financial statements.  The
Company shall not be required to provide such statements to key employees whose
duties in connection with the Company assure their access to equivalent
information.

"Company"), hereby grants to the Optionee named in the Notice of Grant (the
"Optionee"), an option (the "Option") to purchase a total number of shares of

to the terms, definitions and provisions of the 1993 Stock Option Plan (the
"Plan") adopted by the Company, which is incorporated herein by reference.
Unless otherwise defined herein, the terms defined in the Plan shall have the
same defined meanings in this Option Agreement.

     If designated in the Notice of Grant as an Incentive Stock Option, this
Option is intended to qualify as an Incentive Stock Option as defined in Section
422 of the Code.  However, if this Option is intended to be an Incentive Stock
Option, to the extent that it exceeds the $100,000 rule of Code Section 422(d)
it shall be treated as a Nonstatutory Stock Option.

     (b)   Exercise of Option.  This Option shall be exercisable during its term
           ------------------
in accordance with the Exercise Schedule set out in the Notice of Grant and with
the provisions of Section 9 of the Plan as follows:

     (c)   Right to Exercise.
           -----------------

     (i)   This Option may not be exercised for a fraction of a share.

     (ii)  In the event of Optionee's death, disability or other termination of
employment, the exercisability of the Option is governed by Sections 6, 7 and 8
below, subject to the limitation contained in subsection 2(i)(c).

     (iii) In no event may this Option be exercised after the date of expiration
of the term of this Option as set forth in the Notice of Grant.

     (d)   Method of Exercise. This Option shall be exercisable by written
           ------------------
notice (in the form attached as Exhibit A) which shall state the election to
exercise the Option, the number of Shares in respect of which the Option is
being exercised, and such other representations and agreements as to the
holder's investment intent with respect to such shares of Common Stock as may be
required by the Company pursuant to the provisions of the Plan. Such written
notice shall be signed by the Optionee and shall be delivered in person or by
certified mail to the Secretary of the Company. The written notice shall be
accompanied by payment of the Exercise Price. This Option shall be deemed

                                      -2-


to be exercised upon receipt by the Company of such written notice accompanied
by the Exercise Price.

     No Shares will be issued pursuant to the exercise of an Option unless such
issuance and such exercise shall comply with all relevant provisions of law and
the requirements of any stock exchange upon which the Shares may then be listed.
Assuming such compliance, for income tax purposes the Shares shall be considered
transferred to the Optionee on the date on which the Option is exercised with
respect to such Shares.

     3. OPTIONEE'S REPRESENTATIONS.  In the event the Shares purchasable
pursuant to the exercise of this Option have not been registered under the
Securities Act of 1933, as amended ("1933 Act"), at the time this Option is
exercised, Optionee shall, if required by the Company, concurrently with the
exercise of all or any portion of this Option, deliver to the Company his
Investment Representation Statement in the form attached hereto as Exhibit B.

     4. METHOD OF PAYMENT.  Payment of the Exercise Price shall be by any of the
following, or a combination thereof, at the election of the Optionee:

     (a)cash; or

     (b)check; or

     (c)surrender of other shares of Common Stock of the Company which (A) in
the case of Shares acquired pursuant to the exercise of a Company option, have
been owned by the Optionee for more than six (6) months on the date of
surrender, and (B) have a fair market value on the date of surrender equal to
the Exercise Price of the Shares as to which the Option is being exercised; or

     (d)delivery of a properly executed exercise notice together with such other
documentation as the Administrator and the broker, if applicable, shall require
to effect an exercise of the Option and delivery to the Company of the sale or
loan proceeds required to pay the exercise price.

     5. RESTRICTIONS ON EXERCISE.  This Option may not be exercised until such
time as the Plan has been approved by the shareholders of the Company, or if the
issuance of such Shares upon such exercise or the method of payment of
consideration for such shares would constitute a violation of any applicable
federal or state securities or other law or regulation, including any rule under
Part 207 of Title 12 of the Code of Federal Regulations ("Regulation G") as
promulgated by the Federal Reserve Board.  As a condition to the exercise of
this Option, the Company may require Optionee to make any representation and
warranty to the Company as may be required by any applicable law or regulation.

     6. TERMINATION OF RELATIONSHIP. In the event an Optionee's Continuous
Status as an Employee or Consultant terminates, Optionee may, to the extent
otherwise so entitled at the date of such termination (the "Termination Date"),
exercise this Option during the Termination Period set out in the Notice of
Grant. To the extent that Optionee was not entitled to exercise this

                                      -3-


Option at the date of such termination, or if Optionee does not exercise this
Option within the time specified herein, the Option shall terminate.

     7.   DISABILITY OF OPTIONEE.  Notwithstanding the provisions of Section 6
above, in the event of termination of an Optionee's consulting relationship or
Continuous Status as an Employee as a result of his or her disability, Optionee
may, but only within 180 days from the date of such termination (and in no event
later than the expiration date of the term of such Option as set forth in the
Option Agreement), exercise the Option to the extent otherwise entitled to
exercise it at the date of such termination; provided, however, that if such
disability is not a "disability" as such term is defined in Section 22(e)(3) of
the Code, in the case of an Incentive Stock Option such Incentive Stock Option
shall automatically convert to a Nonstatutory Stock Option on the day three
months and one day following such termination.  To the extent that Optionee was
not entitled to exercise the Option at the date of termination, or if Optionee
does not exercise such Option to the extent so entitled within the time
specified herein, the Option shall terminate, and the Shares covered by such
Option shall revert to the Plan.

     8.   DEATH OF OPTIONEE. In the event of termination of Optionee's
Continuous Status as an Employee or Consultant as a result of the death of
Optionee, the Option may be exercised at any time within 180 days following the
date of death (but in no event later than the date of expiration of the term of
this Option as set forth in Section 10 below), by Optionee's estate or by a
person who acquired the right to exercise the Option by bequest or inheritance,
but only to the extent the Optionee could exercise the Option at the date of
death.

     9.   NON-TRANSFERABILITY OF OPTION.  This Option may not be transferred in
any manner otherwise than by will or by the laws of descent or distribution and
may be exercised during the lifetime of Optionee only by him.  The terms of this
Option shall be binding upon the executors, administrators, heirs, successors
and assigns of the Optionee.

     10.  TERM OF OPTION.  This Option may be exercised only within the term set
out in the Notice of Grant, and may be exercised during such term only in
accordance with the Plan and the terms of this Option.  The limitations set out
in Section 7 of the Plan regarding Options designated as Incentive Stock Options
and Options granted to more than ten percent (10%) shareholders shall apply to
this Option.

     11.  TAXATION UPON EXERCISE OF OPTION.  Optionee understands that, upon
exercising a nonstatutory Option, he or she will recognize income for tax
purposes in an amount equal to the excess of the then fair market value of the
Shares over the exercise price.  However, the timing of this income recognition
may be deferred for up to six months if Optionee is subject to Section 16 of the
Securities Exchange Act of 1934, as amended (the "Exchange Act").  If the
Optionee is an employee, the Company will be required to withhold from
Optionee's compensation, or collect from Optionee and pay to the applicable
taxing authorities an amount equal to a percentage of this compensation income.
Additionally, the Optionee may at some point be required to satisfy tax
withholding obligations with respect to the disqualifying disposition of an
Incentive Stock Option.

                                      -4-


The Optionee shall satisfy his or her tax withholding obligation arising upon
the exercise of this Option out of Optionee's compensation or by payment to the
Company.

     12. "MARKET STAND-OFF" AGREEMENT.  Optionee hereby agrees, if requested by
the Company and an underwriter of Common Stock (or other equity securities) of
the Company, not to sell or otherwise transfer or dispose of any Common Stock
(or other equity securities) of the Company held by the Optionee during the 180
day period following the date of the final prospectus of the Company, filed
under the 1993 Act; provided that such agreement will only apply to the first
registration statement of the Company, including any such registration statement
registering shares to be sold on Optionee's behalf to the public in an
underwritten offering.  The Company may impose "stop transfer" instructions with
respect to any shares held by Optionee subject to the foregoing restriction
until the end of such 180 day period.

     13. TAX CONSEQUENCES.  Set forth below is a brief summary as of the date of
this Option of some of the federal and Delaware State tax consequences of
exercise of this Option and disposition of the Shares.  THIS SUMMARY IS
NECESSARILY INCOMPLETE, AND THE TAX LAWS AND REGULATIONS ARE SUBJECT TO CHANGE.
OPTIONEE SHOULD CONSULT A TAX ADVISER BEFORE EXERCISING THIS OPTION OR DISPOSING
OF THE SHARES.

     (a) Exercise of ISO.  If this Option qualifies as an ISO, there will be no
         ---------------
regular federal income tax liability or Delaware State income tax liability upon
the exercise of the Option, although the excess, if any, of the fair market
value of the Shares on the date of exercise over the Exercise Price will be
treated as an adjustment to the alternative minimum tax for federal tax purposes
and may subject the Optionee to the alternative minimum tax in the year of
exercise.

     (b) Exercise of ISO following Disability.  If the Optionee's Continuous
         ------------------------------------
Status as an Employee or Consultant terminates as a result of disability that is
not total and permanent disability as defined in Section 22(e)(3) of the Code,
to the extent permitted on the date of termination, the Optionee must exercise
an ISO within 90 days of such termination for the ISO to be qualified as an ISO.

     (c) Exercise of Nonstatutory Stock Option.  There may be a regular federal
         -------------------------------------
income tax liability and Delaware State income tax liability upon the exercise
of a Nonstatutory Stock Option. The Optionee will be treated as having received
compensation income (taxable at ordinary income tax rates) equal to the excess,
if any, of the fair market value of the Shares on the date of exercise over the
Exercise Price. If Optionee is an employee, the Company will be required to
withhold from Optionee's compensation or collect from Optionee and pay to the
applicable taxing authorities an amount equal to a percentage of this
compensation income at the time of exercise.

     (d) Disposition of Shares.  In the case of an ISO, if Shares are held for
         ---------------------
at least one year, any gain realized on disposition of the Shares will be
treated as long-term capital gain for federal and Delaware State income tax
purposes.  In the case of an ISO, if Shares transferred pursuant to the Option
are held for at least one year after exercise and are disposed of at least two
years after the Date of Grant, any gain realized on disposition of the Shares
will also be treated as long-term capital gain for federal and [state] income
tax purposes.  If Shares purchased under an ISO are disposed of

                                      -5-


within such one-year period or within two years after the Date of Grant, any
gain realized on such disposition will be treated as compensation income
(taxable at ordinary income rates) to the extent of the difference between the
Exercise Price and the lesser of (1) the fair market value of the Shares on the
date of exercise, or (2) the sale price of the Shares.

     (e) Notice of Disqualifying Disposition of ISO Shares.  If the Option
         -------------------------------------------------
granted to Optionee herein is an ISO, and if Optionee sells or otherwise
disposes of any of the Shares acquired pursuant to the ISO on or before the
later of (1) the date two years after the Date of Grant, or (2) the date one
year after the date of exercise, the Optionee shall immediately notify the
Company in writing of such disposition.  Optionee agrees that Optionee may be
subject to income tax withholding by the Company on the compensation income
recognized by the Optionee.

     16. RIGHTS AS SHAREHOLDER.  Until the stock certificate evidencing such
Shares is issued (as evidenced by the appropriate entry on the books of the
Company or of a duly authorized transfer agent of the Company), no right to vote
or receive dividends or any other rights as a shareholder shall exist with
respect to the optioned Stock, notwithstanding the exercise of the Option.  The
Company shall issue (or cause to be issued) such stock certificate promptly
after the Option is exercised.  No adjustment will be made for a dividend or
other right for which the record date is prior to the date the stock certificate
is issued, except as provided in Section 12 of the Plan.

     Optionee shall enjoy rights as a shareholder until such time as Optionee
disposes of the Shares or the Company and/or its assignee(s) exercises the Right
of First Refusal hereunder.  Upon such exercise, Optionee shall have no further
rights as a holder of the Shares so purchased except the right to receive
payment for the Shares so purchased in accordance with the provisions of this
Agreement, and Optionee shall forthwith cause the certificate(s) evidencing the
Shares so purchased to be surrendered to the Company for transfer or
cancellation.

     17. COMPANY'S RIGHT OF FIRST REFUSAL.  Before any Shares held by Optionee
or any transferee (either being sometimes referred to herein as the "Holder")
may be sold or otherwise transferred (including transfer by gift or operation of
law), the Company or its assignee(s) shall have a right of first refusal to
purchase the Shares on the terms and conditions set forth in this Section (the
"Right of First Refusal").


                                      -8-



     (a) Notice of Proposed Transfer.  The Holder of the Shares shall deliver to

intention to sell or otherwise transfer such Shares; (ii) the name of each
proposed purchaser or other transferee ("Proposed Transferee"); (iii) the number

     (b) Exercise of Right of First Refusal.  At any time within thirty (30)
         ----------------------------------
days after receipt of the Notice, the Company and/or its assignee(s) may, by

all, of the Shares proposed to be transferred to any one or more of the Proposed
Transferees, at the purchase price determined in accordance with subsection (c)
below.

     (c) Purchase Price.  The purchase price ("Purchase Price") for the Shares
         --------------
purchased by the Company or its assignee(s) under this Section shall be the
Offered Price.  If the Offered Price includes consideration other than cash, the
cash equivalent value of the non-cash consideration shall be determined by the
Board of Directors of the Company in good faith.

     (d) Payment.  Payment of the Purchase Price shall be made, at the option of
         -------
the Company or its assignee(s), in cash (by check), by cancellation of all or a
portion of any outstanding indebtedness of the Holder to the Company (or, in the
case of repurchase by an assignee, to the assignee), or by any combination
thereof within 30 days after receipt of the Notice or in the manner and at the
times set forth in the Notice.

     (e) Holder's Right to Transfer.  If all of the Shares proposed in the
         --------------------------
Notice to be transferred to a given Proposed Transferee are not purchased by the
Company and/or its assignee(s) as provided in this Section, then the Holder may
sell or otherwise transfer such Shares to that Proposed Transferee at the
Offered Price or at a higher price, provided that such sale or other transfer is
consummated within 120 days after the date of the Notice and provided further
that any such sale or other transfer is effected in accordance with any
applicable securities laws and the Proposed Transferee agrees in writing that
the provisions of this Section shall continue to apply to the Shares in the
hands of such Proposed Transferee.  If the Shares described in the Notice are
not transferred to the Proposed Transferee within such period, a new Notice
shall be given to the Company, and the Company and/or its assignees shall again
be offered the Right of First Refusal before any Shares held by the Holder may
be sold or otherwise transferred.

     (f) Exception for Certain Family Transfers.  Anything to the contrary
         --------------------------------------
contained in this Section notwithstanding, the transfer of any or all of the
Shares during the Optionee's lifetime or on the Optionee's death by will or
intestacy to the Optionee's immediate family or a trust for the benefit of the
Optionee's immediate family shall be exempt from the provisions of this Section.
"Immediate Family" as used herein shall mean spouse, lineal descendant or
antecedent, father, mother, brother or sister.  In such case, the transferee or
other recipient shall receive and hold the Shares so transferred subject to the
provisions of this Section, and there shall be no further transfer of such
Shares except in accordance with the terms of this Section.

Stock of the Company to the general public pursuant to a registration statement
filed with and declared effective by the Securities and Exchange Commission
under the 1933 Act.

     (h)  Tax Consultation.  Optionee understands that Optionee may suffer
          ----------------
adverse tax consequences as a result of Optionee's purchase or disposition of
the Shares.  Optionee represents that Optionee has consulted with any tax
consultants Optionee deems advisable in connection with the purchase or
disposition of the Shares and that Optionee is not relying on the Company for

                      INVESTMENT REPRESENTATION STATEMENT

     OPTIONEE:

     COMPANY: SONIC INNOVATIONS, INC.

     SECURITY: Common Stock

     AMOUNT:

     DATE:

     In connection with the purchase of the above-listed Securities, the
undersigned Optionee represents to the Company the following:

     (a)  Optionee is aware of the Company's business affairs and financial
condition and has acquired sufficient information about the Company to reach an
informed and knowledgeable decision to acquire the securities.  Optionee is
acquiring these securities for investment for Optionee's own account only and
not with a view to, or for resale in connection with, any "distribution" thereof
within the meaning of the Securities Act of 1933, as amended (the "1933 Act").

     (b)  Optionee acknowledges and understands that the securities constitute
"restricted securities" under the 1933 Act and have not been registered under
the 1933 Act in reliance upon a specific exemption therefrom, which exemption
depends upon, among other things, the bona fide nature of Optionee's investment
intent as expressed herein.  In this connection, Optionee understands that, in
the view of the Securities and Exchange Commission, the statutory basis for such
exemption may be unavailable if Optionee's representation was predicated solely
upon a present intention to hold these Securities for the minimum capital gains
period specified under tax statutes, for a deferred sale, for or until an
increase or decrease in the market price of the Securities, or for a period of
one year or any other fixed period in the future.  Optionee further understands
that the Securities must be held indefinitely unless they are subsequently
registered under the 1933 Act or an exemption from such registration is
available.  Optionee further acknowledges and understands that the Company is
under no obligation to register the securities.  Optionee understands that the
certificate evidencing the securities will be imprinted with a legend which
prohibits the transfer of the Securities unless they are

                                     -12-


registered or such registration is not required under federal and applicable
state securities laws, in the opinion of counsel satisfactory to the Company.

     (c)  Optionee is familiar with the provisions of Rule 701 and Rule 144,
each promulgated under the 1933 Act, which, in substance, permit limited public
resale of "restricted securities" acquired, directly or indirectly from the
issuer thereof, in a non-public offering subject to the satisfaction of certain
conditions. Rule 701 provides that if the issuer qualifies under Rule 701 at the
time of the grant of the Option to the Optionee, the exercise will be exempt
from registration under the 1933 Act. In the event the Company becomes subject
to the reporting requirements of Section 13 or 15(d) of the Securities Exchange
Act of 1934, ninety (90) days thereafter (or such longer period as any market
stand-off agreement may require) the securities exempt under Rule 701 may be
resold, subject to the satisfaction of certain of the conditions specified by
Rule 144, including: (1) the resale being made through a broker in an
unsolicited "broker's transaction" or in transactions directly with a market
maker (as said term is defined under the Securities Exchange Act of 1934); and,
in the case of an affiliate, (2) the availability of certain public information
about the Company, (3) the amount of securities being sold during any three
month period not exceeding the limitations specified in Rule 144(e), and (4) the
timely filing of a Form 144, if applicable.

     In the event that the Company does not qualify under Rule 701 at the time
of grant of the Option, then the securities may be resold in certain limited
circumstances subject to the provisions of Rule 144, which requires the resale
to occur not less than two years after the party has purchased, and made full
payment for, within the meaning of Rule 144, the securities to be sold; and, in
the case of an affiliate, or of a non-affiliate who has held the securities less
than three years, the satisfaction of the conditions set forth in sections (1),
(2), (3) and (4) of the paragraph immediately above.

     (d)  Optionee further understands that in the event all of the applicable
requirements of Rule 701 or 144 are not satisfied, registration under the 1933
Act, compliance with Regulation A, or some other registration exemption will be
required; and that, notwithstanding the fact that Rules 144 and 701 are not
exclusive, the Staff of the Securities and Exchange Commission has expressed its
opinion that persons proposing to sell private placement securities other than
in a registered offering and otherwise than pursuant to Rules 144 or 701 will
have a substantial burden of proof in establishing that an exemption from
registration is available for such offers or sales, and that such persons and
their respective brokers who participate in such transactions do so at their own
risk.  Optionee understands that no assurances can be given that any such other
registration exemption will be available in such event.

     Signature of Optionee:

     Unless otherwise defined herein, the terms defined in the Amended and
Restated 1993 Stock Plan shall have the same defined meanings in this Stock

     I.  NOTICE OF STOCK OPTION GRANT
         ----------------------------

     [Optionee's Name and Address]
     -----------------------------


     You have been granted an option to purchase Common Stock of the Company,

                                        ____  Nonstatutory Stock Option

     Term/Expiration Date:              __________________________________

     Exercise and Vesting Schedule:
     -----------------------------

     This Option shall be exercisable in whole or in part, and shall vest
according to the following vesting schedule:

     1/24th of the Shares subject to the Option shall vest each month after the
Vesting Commencement Date, subject to Optionee's continuing to be a Service
Provider on such dates.

     Termination Period:
     ------------------

                                     -14-


     This Option may be exercised, to the extent it is then vested, for three
months after Optionee ceases to be a Service Provider.  Upon death or Disability
of the Optionee, this Option may be exercised, to the extent it is then vested,
for one year after Optionee ceases to be Service Provider.  In no event shall
this Option be exercised later than the Term/Expiration Date as provided above.

     II.  AGREEMENT
          ---------

     1.   Grant of Option. The Administrator of the Company hereby grants to the
          ---------------
Optionee named in the Notice of Grant (the "Optionee"), an option (the "Option")
to purchase the number of Shares set forth in the Notice of Grant, at the
exercise price per Share set forth in the Notice of Grant (the "Exercise
Price"), and subject to the terms and conditions of the Plan, which is
incorporated herein by reference.  Subject to Section 14(c) of the Plan, in the
event of a conflict between the terms and conditions of the Plan and this Option
Agreement, the terms and conditions of the Plan shall prevail.

          If designated in the Notice of Grant as an Incentive Stock Option
("ISO"), this Option is intended to qualify as an Incentive Stock Option as
defined in Section 422 of the Code.  Nevertheless, to the extent that it exceeds
the $100,000 rule of Code Section 422(d), this Option shall be treated as a
Nonstatutory Stock Option ("NSO").

     2.   Exercise of Option.  This Option shall be exercisable during its term
          ------------------
in accordance with the provisions of Section 9 of the Plan as follows:

          (a)  Right to Exercise.
               -----------------

               (i)   Subject to subsections 2(a)(ii) and 2(a)(iii) below, this
Option shall be exercisable cumulatively according to the vesting schedule set
forth in the Notice of Grant. Alternatively, at the election of the Optionee,
this Option may be exercised in whole or in part at any time as to Shares which
have not yet vested. Vested Shares shall not be subject to the Company's
repurchase right (as set forth in the Restricted Stock Purchase Agreement,
attached hereto as Exhibit C-1).
                   -----------

               (ii)  As a condition to exercising this Option for unvested
Shares, the Optionee shall execute the Restricted Stock Purchase Agreement.

               (iii) This Option may not be exercised for a fraction of a Share.

          (b)  Method of Exercise.  This Option shall be exercisable by delivery
               ------------------
of an exercise notice in the form attached as Exhibit A (the "Exercise Notice")
                                              ---------
which shall state the election to exercise the Option, the number of Shares with
respect to which the Option is being exercised, and such other representations
and agreements as may be required by the Company.  The Exercise Notice shall be
accompanied by payment of the aggregate Exercise Price as to all Exercised
Shares.  This

                                     -15-


Option shall be deemed to be exercised upon receipt by the Company of such fully
executed Exercise Notice accompanied by the aggregate Exercise Price.

          No Shares shall be issued pursuant to the exercise of an Option unless
such issuance and such exercise complies with Applicable Laws.  Assuming such
compliance, for income tax purposes the Shares shall be considered transferred
to the Optionee on the date on which the Option is exercised with respect to
such Shares.

     3.   Optionee's Representations.  In the event the Shares to be issued upon
          --------------------------
exercise of an Option have not been registered under the Securities Act of 1933,
as amended, at the time this Option is exercised, the Optionee shall, if
required by the Company, concurrently with the exercise of all or any portion of
this Option, deliver to the Company his or her Investment Representation
Statement in the form attached hereto as Exhibit B.
                                         ---------

     4.   Lock-Up Period.  Optionee hereby agrees that, if so requested by the
          --------------
Company or any representative of the underwriters (the "Managing Underwriter")
in connection with any registration of the offering of any securities of the
Company under the Securities Act, Optionee shall not sell or otherwise transfer
any Shares or other securities of the Company during the 180-day period (or such
shorter period as may be requested in writing by the Managing Underwriter and
agreed to in writing by the Company) (the "Market Standoff Period") following
the date of the final Prospectus contained in a registration statement of the
Company filed under the Securities Act.  Such restriction shall apply only  to
the first registration statement of the Company to become effective under the
Securities Act that includes securities to be sold on behalf of the Company to
the public in an underwritten public offering under the Securities Act.  The
Company may impose stop-transfer instructions with respect to securities subject
to the foregoing restrictions until the end of such Market Standoff Period.

     5.   Method of Payment.  Payment of the aggregate Exercise Price shall be
          -----------------
by any of the following, or a combination thereof, at the election of the
Optionee:

          (a)  cash;

          (b)  check;

          (c)  consideration received by the Company under a formal cashless
exercise program adopted by the Company in connection with the Plan; or

          (d)  surrender of other Shares which, (i) in the case of Shares
acquired upon exercise of an option, have been owned by the Optionee for more
than six (6) months on the date of surrender, and (ii) have a Fair Market Value
on the date of surrender equal to the aggregate Exercise Price of the Exercised
Shares.

     6.   Restrictions on Exercise.  This Option may not be exercised until such
          ------------------------
time as the Plan has been approved by the stockholders of the Company, or if the
issuance of such Shares upon such

                                     -16-


exercise or the method of payment of consideration for such shares would
constitute a violation of any Applicable Law.

     7.   Non-Transferability of Option.  This Option may not be transferred in
          -----------------------------
any manner otherwise than by will or by the laws of descent or distribution and
may be exercised during the lifetime of Optionee only by Optionee.  The terms of
the Plan and this Option Agreement shall be binding upon the executors,
administrators, heirs, successors and assigns of the Optionee.

     8.   Term of Option.  This Option may be exercised only within the term set
          --------------
out in the Notice of Grant, and may be exercised during such term only in
accordance with the Plan and the terms of this Option.

     9.   Tax Consequences.  Set forth below is a brief summary as of the date
          ----------------
of this Option of some of the federal tax consequences of exercise of this
Option and disposition of the Shares.  THIS SUMMARY IS NECESSARILY INCOMPLETE,
AND THE TAX LAWS AND REGULATIONS ARE SUBJECT TO CHANGE.  THE OPTIONEE SHOULD
CONSULT A TAX ADVISER BEFORE EXERCISING THIS OPTION OR DISPOSING OF THE SHARES.

          (a)  Exercise of NSO.  There may be a regular federal income tax
               ---------------
liability upon the exercise of an NSO.  The Optionee will be treated as having
received compensation income (taxable at ordinary income tax rates) equal to the
excess, if any, of the Fair Market Value of the Exercised Shares on the date of
exercise over the Exercise Price.  If Optionee is an Employee or a former
Employee, the Company will be required to withhold from Optionee's compensation
or collect from Optionee and pay to the applicable taxing authorities an amount
in cash equal to a percentage of this compensation income at the time of
exercise, and may refuse to honor the exercise and refuse to deliver Shares if
such withholding amounts are not delivered at the time of exercise.

          (b)  Exercise of ISO.  If this Option qualifies as an ISO, there will
               ---------------
be no regular federal income tax liability upon the exercise of the Option,
although the excess, if any, of the Fair Market Value of the Exercised Shares on
the date of exercise over the Exercise Price will be treated as an adjustment to
the alternative minimum tax for federal tax purposes and may subject the
Optionee to the alternative minimum tax in the year of exercise.

          (c)  Exercise of ISO Following Disability.  If the Optionee ceases to
               ------------------------------------
be an Employee as a result of a disability that is not a total and permanent
disability as defined in Section 22(e)(3) of the Code, to the extent permitted
on the date of termination, the Optionee must exercise an ISO within three
months of such termination for the ISO to be qualified as an ISO.

          (d)  Disposition of Shares.  In the case of an NSO, if Shares are held
               ---------------------
for at least one year, any gain realized on disposition of the Shares will be
treated as long-term capital gain for federal income tax purposes.  In the case
of an ISO, if Shares transferred pursuant to the Option are held for at least
one year after exercise and at least two years after the Date of Grant, any gain
realized on

                                     -17-


disposition of the Shares will also be treated as long-term capital gain for
federal income tax purposes. If Shares purchased under an ISO are disposed of
within one year after exercise or two years after the Date of Grant, any gain
realized on such disposition will be treated as compensation income (taxable at
ordinary income rates) to the extent of the difference between the Exercise
Price of the Exercised Shares and the lesser of (i) the Fair Market Value of the
Exercised Shares on the date of exercise, or (ii) the sale price of the
Exercised Shares. Different rules may apply if the Shares are subject to a
substantial risk of forfeiture (within the meaning of Section 83 of the Code) at
the time of purchase. Any additional gain will be taxed as capital gain, short-
term depending on the period that the ISO Shares were held.

          (e)  Notice of Disqualifying Disposition of ISO Shares.  If the Option
               -------------------------------------------------
granted to Optionee herein is an ISO, and if Optionee sells or otherwise
disposes of any of the Shares acquired pursuant to the ISO on or before the
later of (i) the date two years after the Date of Grant, or (ii) the date one
year after the date of exercise, the Optionee shall immediately notify the
Company in writing of such disposition.  Optionee agrees that Optionee may be
subject to income tax withholding by the Company on the compensation income
recognized by the Optionee.

          (f)  Section 83(b) Election for Unvested Shares Purchased Pursuant to
               ----------------------------------------------------------------
Options.  With respect to the exercise of an Option for unvested Shares, an
- -------
election (the "Election") may be filed by the Optionee with the Internal Revenue
Service, within 30 days of the purchase of the Shares, electing pursuant to
         --------------
Section 83(b) of the Code to be taxed currently on any difference between the
purchase price of the Shares and their Fair Market Value on the date of
purchase.  In the case of an NSO, this will result in a recognition of taxable
income to the Optionee on the date of exercise, measured by the excess, if any,
of the Fair Market Value of the Exercised Shares, at the time the Option is
exercised over the purchase price for the Exercised Shares.  Absent such an
election, taxable income will be measured and recognized by Optionee at the time
or times on which the Company's Repurchase Option lapses.  In the case of an
ISO, such an election will result in a recognition of income to the Optionee for
alternative minimum tax purposes on the date of exercise, measured by the
excess, if any, of the Fair Market Value of the Exercised Shares, at the time
the Option is exercised, over the purchase price for the Exercised Shares.
Absent such an election, alternative minimum taxable income will be measured and
recognized by Optionee at the time or times on which the Company's Repurchase
Option lapses.   Optionee is strongly encouraged to seek the advice of his or
her own tax consultants in connection with the purchase of the Shares and the
advisability of filing of the Election under Section 83(b) of the Code.  A form
of Election under Section 83(b) is attached hereto as Exhibit C-5 for reference.
                                                      -----------

      OPTIONEE ACKNOWLEDGES THAT IT IS OPTIONEE'S SOLE RESPONSIBILITY AND NOT
THE COMPANY'S TO FILE TIMELY THE ELECTION UNDER SECTION 83(b), EVEN IF OPTIONEE
REQUESTS THE COMPANY OR ITS REPRESENTATIVE TO MAKE THIS FILING ON OPTIONEE'S
BEHALF.

                                     -18-


     10.  Entire Agreement; Governing Law.  The Plan is incorporated herein by
          -------------------------------
reference.  The Plan and this Option Agreement constitute the entire agreement
of the parties with respect to the subject matter hereof and supersede in their
entirety all prior undertakings and agreements of the Company and Optionee with
respect to the subject matter hereof, and may not be modified adversely to the
Optionee's interest except by means of a writing signed by the Company and
Optionee.  This Option Agreement is governed by the internal substantive laws
but not the choice of law rules of Utah.

     11.  No Guarantee of Continued Service.  OPTIONEE ACKNOWLEDGES AND AGREES
          ---------------------------------
THAT THE VESTING OF SHARES PURSUANT TO THE VESTING SCHEDULE HEREOF IS EARNED
ONLY BY CONTINUING AS A SERVICE PROVIDER AT THE WILL OF THE COMPANY (NOT THROUGH
THE ACT OF BEING HIRED, BEING GRANTED THIS OPTION OR ACQUIRING SHARES
HEREUNDER).  OPTIONEE FURTHER ACKNOWLEDGES AND AGREES THAT THIS AGREEMENT, THE
TRANSACTIONS CONTEMPLATED HEREUNDER AND THE VESTING SCHEDULE SET FORTH HEREIN DO
NOT CONSTITUTE AN EXPRESS OR IMPLIED PROMISE OF CONTINUED ENGAGEMENT AS A
SERVICE PROVIDER FOR THE VESTING PERIOD, FOR ANY PERIOD, OR AT ALL, AND SHALL
NOT INTERFERE IN ANY WAY WITH OPTIONEE'S RIGHT OR THE COMPANY'S RIGHT TO
TERMINATE OPTIONEE'S RELATIONSHIP AS A SERVICE PROVIDER AT ANY TIME, WITH OR
WITHOUT CAUSE.

     Optionee acknowledges receipt of a copy of the Plan and represents that he
or she is familiar with the terms and provisions thereof, and hereby accepts
this Option subject to all of the terms and provisions thereof.  Optionee has
reviewed the Plan and this Option in their entirety, has had an opportunity to
obtain the advice of counsel prior to executing this Option and fully
understands all provisions of the Option.  Optionee hereby agrees to accept as
binding, conclusive and final all decisions or interpretations of the
Administrator upon any questions arising under the Plan or this Option.
Optionee further agrees to notify the Company upon any change in the residence
address indicated below.

     2.  Delivery of Payment.  Purchaser herewith delivers to the Company the
         -------------------
full purchase price of the Shares, as set forth in the Option Agreement.

     3.  Representations of Optionee.  Optionee acknowledges that Optionee has
         ---------------------------
received, read and understood the Plan and the Option Agreement and agrees to
abide by and be bound by their terms and conditions.

     4.  Rights as Stockholder.  Until the issuance of the Shares (as evidenced
         ---------------------
by the appropriate entry on the books of the Company or of a duly authorized
transfer agent of the Company), no right to vote or receive dividends or any
other rights as a stockholder shall exist with respect to the optioned stock,
notwithstanding the exercise of the Option.  The Shares shall be issued to the
Optionee as soon as practicable after the Option is exercised.  No adjustment
shall be made for a dividend or other right for which the record date is prior
to the date of issuance except as provided in Section 12 of the Plan.

     5.  Company's Right of First Refusal.  Before any Shares held by Optionee
         --------------------------------
or any transferee (either being sometimes referred to herein as the "Holder")
may be sold or otherwise transferred (including transfer by gift or operation of
law), the Company or its assignee(s) shall have a right of first refusal to
purchase the Shares on the terms and conditions set forth in this Section (the
"Right of First Refusal").

                                     -20-


          (a)  Notice of Proposed Transfer.  The Holder of the Shares shall
               ---------------------------
deliver to the Company a written notice (the "Notice") stating:  (i) the
Holder's bona fide intention to sell or otherwise transfer such Shares; (ii) the
name of each proposed purchaser or other transferee ("Proposed Transferee");
(iii) the number of Shares to be transferred to each Proposed Transferee; and
(iv) the bona fide cash price or other consideration for which the Holder
proposes to transfer the Shares (the "Offered Price"), and the Holder shall
offer the Shares at the Offered Price to the Company or its assignee(s).

          (b)  Exercise of Right of First Refusal.  At any time within thirty
               ----------------------------------
(30) days after receipt of the Notice, the Company and/or its assignee(s) may,
by giving written notice to the Holder, elect to purchase all, but not less than
all, of the Shares proposed to be transferred to any one or more of the Proposed
Transferees, at the purchase price determined in accordance with subsection (c)
below.

          (c)  Purchase Price.  The purchase price ("Purchase Price") for the
               --------------
Shares purchased by the Company or its assignee(s) under this Section shall be
the Offered Price.  If the Offered Price includes consideration other than cash,
the cash equivalent value of the non-cash consideration shall be determined by
the Board of Directors of the Company in good faith.

          (d)  Payment.  Payment of the Purchase Price shall be made, at the
               -------
option of the Company or its assignee(s), in cash (by check), by cancellation of
all or a portion of any outstanding indebtedness of the Holder to the Company
(or, in the case of repurchase by an assignee, to the assignee), or by any
combination thereof within 30 days after receipt of the Notice or in the manner
and at the times set forth in the Notice.

          (e)  Holder's Right to Transfer.  If all of the Shares proposed in the
               --------------------------
Notice to be transferred to a given Proposed Transferee are not purchased by the
Company and/or its assignee(s) as provided in this Section, then the Holder may
sell or otherwise transfer such Shares to that Proposed Transferee at the
Offered Price or at a higher price, provided that such sale or other transfer is
consummated within 120 days after the date of the Notice, that any such sale or
other transfer is effected in accordance with any applicable securities laws and
that the Proposed Transferee agrees in writing that the provisions of this
Section shall continue to apply to the Shares in the hands of such Proposed
Transferee.  If the Shares described in the Notice are not transferred to the
Proposed Transferee within such period, a new Notice shall be given to the
Company, and the Company and/or its assignees shall again be offered the Right
of First Refusal before any Shares held by the Holder may be sold or otherwise
transferred.

          (f)  Exception for Certain Family Transfers.  Anything to the contrary
               --------------------------------------
contained in this Section notwithstanding, the transfer of any or all of the
Shares during the Optionee's lifetime or on the Optionee's death by will or
intestacy to the Optionee's immediate family or a trust for the benefit of the
Optionee's immediate family shall be exempt from the provisions of this Section.
"Immediate Family" as used herein shall mean spouse, lineal descendant or
antecedent, father, mother,

                                     -21-


brother or sister. In such case, the transferee or other recipient shall receive
and hold the Shares so transferred subject to the provisions of this Section,
and there shall be no further transfer of such Shares except in accordance with
the terms of this Section.

          (g)  Termination of Right of First Refusal. The Right of First Refusal
               -------------------------------------
shall terminate as to any Shares upon the first sale of Common Stock of the
Company to the general public pursuant to a registration statement filed with
and declared effective by the Securities and Exchange Commission under the
Securities Act of 1933, as amended.

     6.   Tax Consultation.  Optionee understands that Optionee may suffer
          ----------------
adverse tax consequences as a result of Optionee's purchase or disposition of
the Shares.  Optionee represents that Optionee has consulted with any tax
consultants Optionee deems advisable in connection with the purchase or
disposition of the Shares and that Optionee is not relying on the Company for
any tax advice.

     7.   Restrictive Legends and Stop-Transfer Orders.
          --------------------------------------------

          (a)  Legends.  Optionee understands and agrees that the Company shall
               -------
cause the legends set forth below or legends substantially equivalent thereto,
to be placed upon any certificate(s) evidencing ownership of the Shares together

          TRANSFEREES OF THESE SHARES.


                                     -22-


          (b)  Stop-Transfer Notices.  Optionee agrees that, in order to ensure
               ---------------------
compliance with the restrictions referred to herein, the Company may issue

                                   ---------

                      INVESTMENT REPRESENTATION STATEMENT

OPTIONEE              :

COMPANY               :       SONIC INNOVATIONS, INC.

SECURITY              :       COMMON STOCK

AMOUNT                :

DATE                          :

     In connection with the purchase of the above-listed Securities, the
undersigned Optionee represents to the Company the following:

          (a)  Optionee is aware of the Company's business affairs and financial
condition and has acquired sufficient information about the Company to reach an
informed and knowledgeable decision to acquire the Securities.  Optionee is
acquiring these Securities for investment for Optionee's own account only and
not with a view to, or for resale in connection with, any "distribution" thereof
within the meaning of the Securities Act of 1933, as amended (the "Securities
Act").

          (b)  Optionee acknowledges and understands that the Securities
constitute "restricted securities" under the Securities Act and have not been
registered under the Securities Act in reliance upon a specific exemption
therefrom, which exemption depends upon, among other things, the bona fide
nature of Optionee's investment intent as expressed herein. In this connection,
Optionee understands that, in the view of the Securities and Exchange
Commission, the statutory basis for such exemption may be unavailable if
Optionee's representation was predicated solely upon a present intention to hold
these Securities for the minimum capital gains period specified under tax
statutes, for a deferred sale, for or until an increase or decrease in the
market price of the Securities, or for a period of one year or any other fixed
period in the future. Optionee further understands that the Securities must be
held indefinitely unless they are subsequently registered under the Securities
Act or an exemption from such registration is available. Optionee further
acknowledges and understands that the Company is under no obligation to register
the Securities. Optionee understands that the certificate evidencing the
Securities will be imprinted with a legend which prohibits the transfer of the
Securities unless they are registered or such registration is not required in
the opinion of counsel satisfactory to the Company, and with any other legend
required under applicable state securities laws.

                                     -25-


          (c)  Optionee is familiar with the provisions of Rule 701 and Rule
144, each promulgated under the Securities Act, which, in substance, permit
limited public resale of "restricted securities" acquired, directly or
indirectly from the issuer thereof, in a non-public offering subject to the
satisfaction of certain conditions. Rule 701 provides that if the issuer
qualifies under Rule 701 at the time of the grant of the Option to the Optionee,
the exercise will be exempt from registration under the Securities Act. In the
event the Company becomes subject to the reporting requirements of Section 13 or
15(d) of the Securities Exchange Act of 1934, ninety (90) days thereafter (or
such longer period as any market stand-off agreement may require) the Securities
exempt under Rule 701 may be resold, subject to the satisfaction of certain of
the conditions specified by Rule 144, including: (1) the resale being made
through a broker in an unsolicited "broker's transaction" or in transactions
directly with a market maker (as said term is defined under the Securities
Exchange Act of 1934); and, in the case of an affiliate, (2) the availability of
certain public information about the Company, (3) the amount of Securities being
sold during any three month period not exceeding the limitations specified in
Rule 144(e), and (4) the timely filing of a Form 144, if applicable.

     In the event that the Company does not qualify under Rule 701 at the time
of grant of the Option, then the Securities may be resold in certain limited
circumstances subject to the provisions of Rule 144, which requires the resale
to occur not less than one year after the later of the date the Securities were
sold by the Company or the date the Securities were sold by an affiliate of the
Company, within the meaning of Rule 144; and, in the case of acquisition of the
Securities by an affiliate, or by a non-affiliate who subsequently holds the
Securities less than two years, the satisfaction of the conditions set forth in
sections (1), (2), (3) and (4) of the paragraph immediately above.

          (d)  Optionee further understands that in the event all of the
applicable requirements of Rule 701 or 144 are not satisfied, registration under
the Securities Act, compliance with Regulation A, or some other registration
exemption will be required; and that, notwithstanding the fact that Rules 144
and 701 are not exclusive, the Staff of the Securities and Exchange Commission
has expressed its opinion that persons proposing to sell private placement
securities other than in a registered offering and otherwise than pursuant to
Rules 144 or 701 will have a substantial burden of proof in establishing that an
exemption from registration is available for such offers or sales, and that such
persons and their respective brokers who participate in such transactions do so
at their own risk.  Optionee understands that no assurances can be given that
any such other registration exemption will be available in such event.

                                    Signature of Optionee:

                                    ___________________________________

                     AMENDED AND RESTATED 1993 STOCK PLAN
                      RESTRICTED STOCK PURCHASE AGREEMENT

     THIS AGREEMENT is made between ____________________________________ (the
"Purchaser") and Sonic Innovations, Inc. (the "Company") as of_________________,
199__.

     Unless otherwise defined herein, the terms defined in the Amended and
Restated 1993 Stock Plan shall have the same defined meanings in this Agreement.

                                   RECITALS
                                   --------

     A.   Pursuant to the exercise of the option (grant number ____) granted to
Purchaser under the Plan and pursuant to the Option Agreement dated ___________
by and between the Company and Purchaser with respect to such grant (the
"Option"), which Plan and Option Agreement are hereby incorporated by reference,
Purchaser has elected to purchase _________ of those shares of Common Stock
which have not become vested under the vesting schedule set forth in the Option
Agreement ("Unvested Shares").  The Unvested Shares and the shares subject to
the Option Agreement which have become vested are sometimes collectively
referred to herein as the "Shares".

     B.   As required by the Option Agreement, as a condition to Purchaser's
election to exercise the option, Purchaser must execute this Agreement, which
sets forth the rights and obligations of the parties with respect to Shares
acquired upon exercise of the Option.

     1.   Repurchase Option.
          -----------------

          (a)  If Purchaser's status as a Service Provider is terminated for any
reason, including for cause, death, and Disability, the Company shall have the
right and option to purchase from Purchaser, or Purchaser's personal
representative, as the case may be, all of the Purchaser's Unvested Shares as of
the date of such termination at the price paid by the Purchaser for such Shares
(the "Repurchase Option").

          (b)  Upon the occurrence of such termination, the Company may exercise
its Repurchase Option by delivering personally or by registered mail, to
Purchaser (or his transferee or legal representative, as the case may be),
within ninety (90) days of the termination, a notice in writing indicating the
Company's intention to exercise the Repurchase Option and setting forth a date
for closing not later than thirty (30) days from the mailing of such notice. The
closing shall take place at the Company's office. At the closing, the holder of
the certificates for the Unvested Shares being transferred shall deliver the
stock certificate

                                      -3-


or certificates evidencing the Unvested Shares, and the Company shall deliver
the purchase price therefor.

          (c)  At its option, the Company may elect to make payment for the
Unvested Shares to a bank selected by the Company. The Company shall avail
itself of this option by a notice in writing to Purchaser stating the name and
address of the bank, date of closing, and waiving the closing at the Company's
office.

          (d)  If the Company does not elect to exercise the Repurchase Option
conferred above by giving the requisite notice within ninety (90) days following
the termination, the Repurchase Option shall terminate.

          (e)  The Repurchase Option shall terminate in accordance with the
vesting schedule contained in Optionee's Option Agreement.

     2.   Transferability of the Shares; Escrow.
          -------------------------------------

          (a)  Purchaser hereby authorizes and directs the Secretary of the
Company, or such other person designated by the Company, to transfer the
Unvested Shares as to which the Repurchase Option has been exercised from
Purchaser to the Company.

          (b)  To insure the availability for delivery of Purchaser's Unvested
Shares upon repurchase by the Company pursuant to the Repurchase Option under
Section 1, Purchaser hereby appoints the Secretary, or any other person
designated by the Company as escrow agent, as its attorney-in-fact to sell,
assign and transfer unto the Company, such Unvested Shares, if any, repurchased
by the Company pursuant to the Repurchase Option and shall, upon execution of
this Agreement, deliver and deposit with the Secretary of the Company, or such
other person designated by the Company, the share certificates representing the
Unvested Shares, together with the stock assignment duly endorsed in blank,
attached hereto as Exhibit C-2. The Unvested Shares and stock assignment shall
                   -----------
be held by the secretary in escrow, pursuant to the Joint Escrow Instructions of
the Company and Purchaser attached as Exhibit C-3 hereto, until the Company
                                      -----------
exercises its Repurchase Option, until such Unvested Shares are vested, or until
such time as this Agreement no longer is in effect. As a further condition to
the Company's obligations under this Agreement, the spouse of the Purchaser, if
any, shall execute and deliver to the Company the Consent of Spouse attached
hereto as Exhibit C-4. Upon vesting of the Unvested Shares, the escrow agent
          -----------
shall promptly deliver to the Purchaser the certificate or certificates
representing such Shares in the escrow agent's possession belonging to the
Purchaser, and the escrow agent shall be discharged of all further obligations
hereunder; provided, however, that the escrow agent shall nevertheless retain
such certificate or certificates as escrow agent if so required pursuant to
other restrictions imposed pursuant to this Agreement.

                                      -4-


          (c)  The Company, or its designee, shall not be liable for any act it
may do or omit to do with respect to holding the Shares in escrow and while
acting in good faith and in the exercise of its judgment.

          (d)  Transfer or sale of the Shares is subject to restrictions on
transfer imposed by any applicable state and federal securities laws. Any
transferee shall hold such Shares subject to all the provisions hereof and the
Exercise Notice executed by the Purchaser with respect to any Unvested Shares
purchased by Purchaser and shall acknowledge the same by signing a copy of this
Agreement.

     3.   Ownership, Voting Rights, Duties. This Agreement shall not affect in
          --------------------------------
any way the ownership, voting rights or other rights or duties of Purchaser,
except as specifically provided herein.

     4.   Legends.  The share certificate evidencing the Shares issued hereunder
          -------
shall be endorsed with the following legend (in addition to any legend required
under applicable federal and state securities laws):

     THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN
RESTRICTIONS UPON TRANSFER AND RIGHTS OF REPURCHASE AS SET FORTH IN AN AGREEMENT
BETWEEN THE COMPANY AND THE STOCKHOLDER, A COPY OF WHICH IS ON FILE WITH THE
SECRETARY OF THE COMPANY.

     5.   Adjustment for Stock Split. All references to the number of Shares and
          --------------------------
the purchase price of the Shares in this Agreement shall be appropriately
adjusted to reflect any stock split, stock dividend or other change in the
Shares which may be made by the Company pursuant to Section 12 of the Plan after
the date of this Agreement.

     6.   Notices.  Notices required hereunder shall be given in person or by
          -------
registered mail to the address of Purchaser shown on the records of the Company,
and to the Company at their respective principal executive offices.

     7.   Survival of Terms. This Agreement shall apply to and bind Purchaser
          -----------------
and the Company and their respective permitted assignees and transferees, heirs,
legatees, executors, administrators and legal successors.


     8.   Section 83(b) Election. Purchaser hereby acknowledges that he or she
has been informed that, with respect to the exercise of an Option for Unvested
Shares, an election (the "Election") may be filed by the Purchaser with the
Internal Revenue Service, within 30 days of the purchase of the exercised
                          --------------
Shares, electing pursuant to Section 83(b) of the Code to be taxed

                                      -5-


currently on any difference between the purchase price of the exercised Shares
and their Fair Market Value on the date of purchase. In the case of a
Nonstatutory Stock Option, this will result in a recognition of taxable income
to the Purchaser on the date of exercise, measured by the excess, if any, of the
Fair Market Value of the exercised Shares, at the time the Option is exercised
over the purchase price for the exercised Shares. Absent such an Election,
taxable income will be measured and recognized by Purchaser at the time or times
on which the Company's Repurchase Option lapses. In the case of an Incentive
Stock Option, such an Election will result in a recognition of income to the
Purchaser for alternative minimum tax purposes on the date of exercise, measured
by the excess, if any, of the Fair Market Value of the exercised Shares, at the
time the option is exercised, over the purchase price for the exercised Shares.
Absent such an Election, alternative minimum taxable income will be measured and
recognized by Purchaser at the time or times on which the Company's Repurchase
Option lapses. Purchaser is strongly encouraged to seek the advice of his or her
own tax consultants in connection with the purchase of the Shares and the
advisability of filing of the Election under Section 83(b) of the Code. A form
of Election under Section 83(b) is attached hereto as Exhibit C-5 for reference.
                                                      -----------

     PURCHASER ACKNOWLEDGES THAT IT IS PURCHASER'S SOLE RESPONSIBILITY AND NOT
THE COMPANY'S TO FILE TIMELY THE ELECTION UNDER SECTION 83(b) OF THE CODE, EVEN
IF PURCHASER REQUESTS THE COMPANY OR ITS REPRESENTATIVE TO MAKE THIS FILING ON
PURCHASER'S BEHALF.

     9.   Representations.  Purchaser has reviewed with his own tax advisors the
          ---------------
federal, state, local and foreign tax consequences of this investment and the
transactions contemplated by this Agreement.  Purchaser is relying solely on
such advisors and not on any statements or representations of the Company or any
of its agents.  Purchaser understands that he (and not the Company) shall be
responsible for his own tax liability that may arise as a result of this
investment or the transactions contemplated by this Agreement.

     10   Governing Law.  This Agreement shall be governed by the internal
          -------------
substantive laws, but not the choice of law rules, of Utah.

     Purchaser represents that he has read this Agreement and is familiar with
its terms and provisions. Purchaser hereby agrees to accept as binding,
conclusive and final all decisions or interpretations of the Board upon any

Attention:  Secretary

Dear _________________:

          As Escrow Agent for both Sonic Innovations, Inc. (the "Company"), and
the undersigned purchaser of stock of the Company (the "Purchaser"), you are
hereby authorized and directed to hold the documents delivered to you pursuant
to the terms of that certain Restricted Stock Purchase Agreement ("Agreement")
between the Company and the undersigned, in accordance with the following
instructions:

          1    In the event the Company and/or any assignee of the Company
(referred to collectively for convenience herein as the "Company") exercises the
Company's repurchase option set forth in the Agreement, the Company shall give
to Purchaser and you a written notice specifying the number of shares of stock
to be purchased, the purchase price, and the time for a closing hereunder at the
principal office of the Company. Purchaser and the Company hereby irrevocably
authorize and direct you to close the transaction contemplated by such notice in
accordance with the terms of said notice.

          2    At the closing, you are directed (a) to date the stock
assignments necessary for the transfer in question, (b) to fill in the number of
shares being transferred, and (c) to deliver the stock assignments, together
with the certificate evidencing the shares of stock to be transferred, to the
Company or its assignee, against the simultaneous delivery to you of the
purchase price (by cash, a check, or some combination thereof) for the number of
shares of stock being purchased pursuant to the exercise of the Company's
repurchase option.


          3    Purchaser irrevocably authorizes the Company to deposit with you
any certificates evidencing shares of stock to be held by you hereunder and any
additions and substitutions to said shares as defined in the Agreement.
Purchaser does hereby irrevocably constitute and appoint you as Purchaser's
attorney-in-fact and agent for the term of this escrow to execute with respect
to such securities all documents necessary or appropriate to make such
securities negotiable and to complete any transaction herein contemplated,
including but not limited to the filing with any applicable state blue sky
authority of any required applications for consent to, or notice of transfer of,
the securities. Subject to the provisions of this paragraph 3, Purchaser shall
exercise all rights and privileges of a stockholder of the Company while the
stock is held by you.

          4    Upon written request of the Purchaser, but no more than once per
calendar year, unless the Company's repurchase option has been exercised, you
will deliver to Purchaser a certificate or certificates representing so many
shares of stock as are not then subject to the Company's repurchase option.
Within 120 days after cessation of Purchaser's continuous employment by or
services to the Company, or any parent or subsidiary of the Company, you will
deliver to Purchaser a certificate or certificates representing the aggregate
number of shares held or issued pursuant to the Agreement and not purchased by
the Company or its assignees pursuant to exercise of the Company's repurchase
option.

          5    If at the time of termination of this escrow you should have in
your possession any documents, securities, or other property belonging to
Purchaser, you shall deliver all of the same to Purchaser and shall be
discharged of all further obligations hereunder.

          6    Your duties hereunder may be altered, amended, modified or
revoked only by a writing signed by all of the parties hereto.

          7    You shall be obligated only for the performance of such duties as
are specifically set forth herein and may rely and shall be protected in relying
or refraining from acting on any instrument reasonably believed by you to be
genuine and to have been signed or presented by the proper party or parties. You
shall not be personally liable for any act you may do or omit to do hereunder as
Escrow Agent or as attorney-in-fact for Purchaser while acting in good faith,
and any act done or omitted by you pursuant to the advice of your own attorneys
shall be conclusive evidence of such good faith.

          8    You are hereby expressly authorized to disregard any and all
warnings given by any of the parties hereto or by any other person or
corporation, excepting only orders or process of courts of law and are hereby
expressly authorized to comply with and obey orders, judgments or decrees of any
court. In case you obey or comply with any such order, judgment or decree, you
shall not be liable to any of the parties hereto or to any other person, firm or
corporation by reason of such compliance, notwithstanding any such order,
judgment or decree being subsequently reversed, modified, annulled, set aside,
vacated or found to have been entered without jurisdiction.

                                      -2-


          9    You shall not be liable in any respect on account of the
identity, authorities or rights of the parties executing or delivering or
purporting to execute or deliver the Agreement or any documents or papers
deposited or called for hereunder.

          10   You shall not be liable for the outlawing of any rights under the
Statute of Limitations with respect to these Joint Escrow Instructions or any
documents deposited with you.

          11   You shall be entitled to employ such legal counsel and other
experts as you may deem necessary properly to advise you in connection with your
obligations hereunder, may rely upon the advice of such counsel, and may pay
such counsel reasonable compensation therefor.

          12   Your responsibilities as Escrow Agent hereunder shall terminate
if you shall cease to be an officer or agent of the Company or if you shall
resign by written notice to each party. In the event of any such termination,
the Company shall appoint a successor Escrow Agent.

          13   If you reasonably require other or further instruments in
connection with these Joint Escrow Instructions or obligations in respect
hereto, the necessary parties hereto shall join in furnishing such instruments.

          14   It is understood and agreed that should any dispute arise with
respect to the delivery and/or ownership or right of possession of the
securities held by you hereunder, you are authorized and directed to retain in
your possession without liability to anyone all or any part of said securities
until such disputes shall have been settled either by mutual written agreement
of the parties concerned or by a final order, decree or judgment of a court of
competent jurisdiction after the time for appeal has expired and no appeal has
been perfected, but you shall be under no duty whatsoever to institute or defend
any such proceedings.

          15   Any notice required or permitted hereunder shall be given in
writing and shall be deemed effectively given upon personal delivery or upon
deposit in the United States Post Office, by registered or certified mail with
postage and fees prepaid, addressed to each of the other parties thereunto
entitled at the following addresses or at such other addresses as a party may
designate by ten days' advance written notice to each of the other parties
hereto.

          16   By signing these Joint Escrow Instructions, you become a party
hereto only for the purpose of said Joint Escrow Instructions; you do not become
a party to the Agreement.

          17   This instrument shall be binding upon and inure to the benefit of
the parties hereto, and their respective successors and permitted assigns.

                                      -3-


          18   These Joint Escrow Instructions shall be governed by the internal
substantive laws, but not the choice of law rules, of Utah.
