                  INFORMATION REQUIRED IN THE REGISTRATION STATEMENT


Item 3.  INCORPORATION OF DOCUMENTS BY REFERENCE

    Advanced Fibre Communications, Inc. (the "Registrant") hereby incorporates
by reference into this Registration Statement the following documents previously
filed with the Securities and Exchange Commission (the "SEC"):

    (a)  The Registrant's Prospectus filed with the SEC pursuant to Rule 424(b)
         of the Securities Act of 1933, as amended (the "1933 Act"), in
         connection with Registration Statement No. 333-08921  on Form S-1,
         filed with the SEC on July 26, 1996, and the amendments thereto, in
         which there is set forth audited financial statements for the
         Registrant's fiscal year ended December 31, 1995; and

    (b)  The Registrant's Registration Statement No. 00-028734 on Form 8-A
         filed with the SEC on July 31, 1996 pursuant to Section 12 of the
         Securities Exchange Act of 1934, as amended (the "1934 Act"), in which
         there is described the terms, rights and provisions applicable to the
         Registrant's outstanding Common Stock.

    All reports and definitive proxy or information statements filed pursuant
to Section 13(a), 13(c), 14 or 15(d) of the 1934 Act after the date of this
Registration Statement and prior to the filing of a post-effective amendment
which indicates that all securities offered hereby have been sold or which
deregisters all securities then remaining unsold shall be deemed to be
incorporated by reference into this Registration Statement and to be a part
hereof from the date of filing of such documents.  Any statement contained in a
document incorporated or deemed to be incorporated by reference herein shall be
deemed to be modified or superseded for purposes of this Registration Statement
to the extent that a statement contained herein or in any subsequently filed
document which also is deemed to be incorporated by reference herein modifies or
supersedes such statement.  Any such statement so modified or superseded shall
not be deemed, except as so modified or superseded, to constitute a part of this
Registration Statement.


Item 4.  DESCRIPTION OF SECURITIES

         Not Applicable.


Item 5.  INTERESTS OF NAMED EXPERTS AND COUNSEL

         Not Applicable.


Item 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

         The Registrant's certificate of incorporation limits the liability of
directors to the maximum extent permitted by Delaware law.  This provision is
intended to allow the Registrant's directors the benefit of Delaware General
Corporation Law which provides that directors of Delaware corporations may be
relieved of monetary liability for breach of their fiduciary duties as
directors, except under certain circumstances, including breach of their duty of
loyalty, acts or omissions not in good faith or involving intentional misconduct
or a knowing violation of law, unlawful payments or dividends or unlawful stock
repurchases or redemptions or any transaction from which the director derived an
improper personal benefit.  As a result, the Registrant and its stockholders may
be unable to obtain monetary damages from a director for breach of conduct if
equitable remedies are not available.  In addition, the Registrant's bylaws
provide that the Registrant shall indemnify its executive officers and directors
to the fullest extent provided by Delaware law.  The bylaws also authorize the
use of indemnification agreements, and the Registrant has entered into such
agreements with each of its directors and executive officers.  Insofar as
indemnification for liabilities arising under the Securities Act may be provided
to the Registrant's executive officers and directors, the Registrant has been
advised that, in the opinion of the Securities and Exchange Commission, such
indemnification is against public policy as expressed in the Securities Act, and
is, therefore, unenforceable.

Item 9.   UNDERTAKINGS

     A.        The undersigned Registrant hereby undertakes:  (1) to file,
during any period in which offers or sales are being made, a post-effective
amendment to this Registration Statement (i) to include any prospectus required
by Section 10(a)(3) of the 1933 Act, (ii) to reflect in the prospectus any facts
or events arising after the effective date of this Registration Statement (or
the most recent post-effective amendment thereof) which, individually or in the
aggregate, represent a fundamental change in the information set forth in this
Registration Statement and (iii) to include any material information with
respect to the plan of distribution not previously disclosed in this
Registration Statement or any material change to such information in this
Registration Statement; PROVIDED, however, that clauses (1)(i) and (1)(ii) shall
not apply if the information required to be included in a post-effective
amendment by those paragraphs is contained in periodic reports filed by the
Registrant pursuant to Section 13 or Section 15(d) of the 1934 Act that are
incorporated by reference into this Registration Statement; (2) that for the
purpose of determining any liability under the 1933 Act each such post-effective
amendment shall be deemed to be a new registration statement relating to the
securities offered therein and the offering of such securities at that time
shall be deemed to be the initial bona fide offering thereof; and (3) to remove
from registration by means of a post-effective amendment any of the securities
being registered which remain unsold at the termination of the Registrant's 1996
Stock Incentive Plan and/or the Employee Stock Purchase Plan.


                                        II-2.

<PAGE>

     B.        The undersigned Registrant hereby undertakes that, for purposes
of determining any liability under the 1933 Act, each filing of the Registrant's
annual report pursuant to Section 13(a) or Section 15(d) of the 1934 Act that is
incorporated by reference into this Registration Statement shall be deemed to be
a new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

     C.        Insofar as indemnification for liabilities arising under the 1933
Act may be permitted to directors, officers, or controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that, in the opinion of the SEC, such indemnification is
against public policy as expressed in the 1933 Act, and is, therefore,
unenforceable.  In the event that a claim for indemnification against such
liabilities (other than the payment by the Registrant of expenses incurred or
paid by a director, officer, or controlling person of the Registrant in the
successful defense of any action, suit, or proceeding) is asserted by such
director, officer, or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the 1933 Act and will be governed by the final
adjudication of such issue.

amended, the Registrant certifies that it has reasonable grounds to believe that

this Registration Statement to be signed on its behalf by the undersigned,

                         ADVANCED FIBRE COMMUNICATIONS, INC.
                              1996 STOCK INCENTIVE PLAN

                  (all share numbers have been adjusted to reflect a
                   two-for-one stock split effected in August 1996)


                                     ARTICLE ONE

                                  GENERAL PROVISIONS

         I.   PURPOSE OF THE PLAN

         This 1996 Stock Incentive Plan is intended to promote the interests of
Advanced Fibre Communications, Inc., a Delaware corporation, by providing
eligible persons with the opportunity to acquire a proprietary interest, or
otherwise increase their proprietary interest, in the Corporation as an
incentive for them to remain in the service of the Corporation.

         Capitalized terms shall have the meanings assigned to such terms in
the attached Appendix.

  II.    STRUCTURE OF THE PLAN

         A.   The Plan shall be divided into five separate equity programs:

              -    the Discretionary Option Grant Program under which eligible
persons may, at the discretion of the Plan Administrator, be granted options to
purchase shares of Common Stock,

              -    the Salary Investment Option Grant Program under which
eligible employees may elect to have a portion of their base salary invested
each year in special below-market option grants,

              -    the Stock Issuance Program under which eligible persons may,
at the discretion of the Plan Administrator, be issued shares of Common Stock
directly, either through the immediate purchase of such shares or as a bonus for
services rendered the Corporation (or any Parent or Subsidiary),

              -    the Automatic Option Grant Program under which eligible
non-employee Board members shall automatically receive option grants at periodic
intervals to purchase shares of Common Stock, and

<PAGE>

              -    the Director Fee Option Grant Program under which
non-employee Board members may elect to have all or any portion of their annual
retainer fee otherwise payable in cash applied to a special below-market option
grant.

         B.   The provisions of Articles One and Seven shall apply to all
equity programs under the Plan and shall govern the interests of all persons
under the Plan.

 III.    ADMINISTRATION OF THE PLAN

         A.   Prior to the Section 12 Registration Date, the Discretionary
Option Grant and Stock Issuance Programs shall be administered by the Board.
Beginning with the Section 12 Registration Date, the Primary Committee shall
have sole and exclusive authority to administer the Discretionary Option Grant
and Stock Issuance Programs with respect to Section 16 Insiders and shall have
sole and exclusive authority to administer the Salary Investment Option Grant
Program with respect to all eligible individuals.

         B.   Administration of the Discretionary Option Grant and Stock
Issuance Programs with respect to all other persons eligible to participate in
those programs may, at the Board's discretion, be vested in the Primary
Committee or a Secondary Committee, or the Board may retain the power to
administer those programs with respect to all such persons.  The members of the
Secondary Committee may be Board members who are Employees eligible to receive
discretionary option grants or direct stock issuances under the Plan or any
other stock option, stock appreciation, stock bonus or other stock plan of the
Corporation (or any Parent or Subsidiary).

         C.   Members of the Primary Committee or any Secondary Committee shall
serve for such period of time as the Board may determine and may be removed by
the Board at any time.  The Board may also at any time terminate the functions
of any Secondary Committee and reassume all powers and authority previously
delegated to such committee.

         D.   Each Plan Administrator shall, within the scope of its
administrative functions under the Plan, have full power and authority (subject
to the provisions of the Plan) to establish such rules and regulations as it may
deem appropriate for proper administration of the Discretionary Option Grant,
Salary Investment Option Grant and Stock Issuance Programs and to make such
determinations under, and issue such interpretations of, the provisions of such
programs and any outstanding options or stock issuances thereunder as it may
deem necessary or advisable.  Decisions of the Plan Administrator within the
scope of its administrative functions under the Plan shall be final and binding
on all parties who have an interest in the Discretionary Option Grant, Salary
Investment Option Grant and Stock Issuance Programs under its jurisdiction or
any option or stock issuance thereunder.


                                          2.

<PAGE>

         E.   Service on the Primary Committee or the Secondary Committee shall
constitute service as a Board member, and members of each such committee shall
accordingly be entitled to full indemnification and reimbursement as Board
members for their service on such committee.  No member of the Primary Committee
or the Secondary Committee shall be liable for any act or omission made in good
faith with respect to the Plan or any option grants or stock issuances under the
Plan.

         F.   Administration of the Automatic Option Grant and Director Fee
Option Grant Programs shall be self-executing in accordance with the terms of
that program, and no Plan Administrator shall exercise any discretionary
functions with respect to any option grants or stock issuances made under those
programs.

  IV.    ELIGIBILITY

         A.   The persons eligible to participate in the Discretionary Option
Grant and Stock Issuance Programs are as follows:

                (i)     Employees,

               (ii)     non-employee members of the Board or the board of
    directors of any Parent or Subsidiary, and

              (iii)     consultants and other independent advisors who
    provide services to the Corporation (or any Parent or Subsidiary).

         B.   Only Section 16 Insiders and other highly compensated Employees
shall be eligible to participate in the Salary Investment Option Grant Program.

         C.   Each Plan Administrator shall, within the scope of its
administrative jurisdiction under the Plan, have full authority to determine,
(i) with respect to the option grants under the Discretionary Option Grant
Program, which eligible persons are to receive option grants, the time or times
when such option grants are to be made, the number of shares to be covered by
each such grant, the status of the granted option as either an Incentive Option
or a Non-Statutory Option, the time or times when each option is to become
exercisable, the vesting schedule (if any) applicable to the option shares and
the maximum term for which the option is to remain outstanding and (ii) with
respect to stock issuances under the Stock Issuance Program, which eligible
persons are to receive stock issuances, the time or times when such issuances
are to be made, the number of shares to be issued to each Participant, the
vesting schedule (if any) applicable to the issued shares and the consideration
for such shares.

         D.   The Plan Administrator shall have the absolute discretion either
to grant options in accordance with the Discretionary Option Grant Program or to
effect stock issuances in accordance with the Stock Issuance Program.


                                          3.

<PAGE>

         E.   The individuals who shall be eligible to participate in the
Automatic Option Grant Program shall be limited to (i) those individuals who
first become non-employee Board members after June 30, 1996, whether through
appointment by the Board or election by the Corporation's stockholders, and
(ii) those individuals who continue to serve as non-employee Board members at
one or more Annual Stockholders Meetings held after the Underwriting Date.  A
non-employee Board member who has previously been in the employ of the
Corporation (or any Parent or Subsidiary) shall not be eligible to receive an
option grant under the Automatic Option Grant Program at the time he or she
first becomes a non-employee Board member, but shall be eligible to receive
periodic option grants under the Automatic Option Grant Program while he or she
continues to serve as a non-employee Board member.

         F.   All non-employee Board members shall be eligible to participate
in the Director Fee Option Grant Program.

   V.    STOCK SUBJECT TO THE PLAN

         A.   The stock issuable under the Plan shall be shares of authorized
but unissued or reacquired Common Stock, including shares repurchased by the
Corporation on the open market.  The maximum number of shares of Common Stock
initially reserved for issuance over the term of the Plan shall not exceed
7,175,676 shares.  Such authorized share reserve is comprised of (i) the number
of shares which remain available for issuance, as of the Plan Effective Date,
under the Predecessor Plan as last approved by the Corporation's stockholders,
including the shares subject to the outstanding options to be incorporated into
the Plan and the additional shares which would otherwise be available for future
grant,(1) plus (ii) an additional increase of 1,000,000 shares authorized by the
Board but subject to stockholder approval prior to the Section 12 Registration
Date.

         B.   The number of shares of Common Stock available for issuance under
the Plan shall automatically increase on the first trading day of each calendar
year during the term of the Plan, beginning with the 1997 calendar year, by an
amount equal to three percent (3.0%) of the shares of Common Stock outstanding
on the last trading day of the immediately preceding calendar year. No Incentive
Options may be granted on the basis of the additional shares of Common Stock
resulting from such annual increases.

         C.   No one person participating in the Plan may receive options,
separately exercisable stock appreciation rights and direct stock issuances for
more than 400,000 shares of Common Stock in the aggregate per calendar year,
beginning with the 1996 calendar year.


- -----------------

(1) Estimated to be 6,175,676 shares of Common Stock as of June 30, 1996.


                                          4.

<PAGE>

         D.   Shares of Common Stock subject to outstanding options (including
options incorporated into this Plan from the Predecessor Plan) shall be
available for subsequent issuance under the Plan to the extent those options
expire or terminate for any reason prior to exercise in full.  Unvested shares
issued under the Plan and subsequently cancelled or repurchased by the
Corporation, at the original issue price paid per share, pursuant to the
Corporation's repurchase rights under the Plan shall be added back to the number
of shares of Common Stock reserved for issuance under the Plan and shall
accordingly be available for reissuance through one or more subsequent option
grants or direct stock issuances under the Plan.  However, should the exercise
price of an option under the Plan be paid with shares of Common Stock or should
shares of Common Stock otherwise issuable under the Plan be withheld by the
Corporation in satisfaction of the withholding taxes incurred in connection with
the exercise of an option or the vesting of a stock issuance under the Plan,
then the number of shares of Common Stock available for issuance under the Plan
shall be reduced by the gross number of shares for which the option is exercised
or which vest under the stock issuance, and not by the net number of shares of
Common Stock issued to the holder of such option or stock issuance.  Shares of
Common Stock underlying one or more stock appreciation rights exercised under
the Discretionary Option Grant Program shall not be available for subsequent
issuance under the Plan.

         E.   If any change is made to the Common Stock by reason of any stock
split, stock dividend, recapitalization, combination of shares, exchange of
shares or other change affecting the outstanding Common Stock as a class without
the Corporation's receipt of consideration, appropriate adjustments shall be
made to (i) the maximum number and/or class of securities issuable under the
Plan, (ii) the number and/or class of securities for which any one person may be
granted stock options, separately exercisable stock appreciation rights and
direct stock issuances under this Plan per calendar year, (iii) the number
and/or class of securities for which grants are subsequently to be made under
the Automatic Option Grant Program to new and continuing non-employee Board
members, (iv) the number and/or class of securities and the exercise price per
share in effect under each outstanding option under the Plan and (v) the number
and/or class of securities and price per share in effect under each outstanding
option incorporated into this Plan from the Predecessor Plan.  Such adjustments
to the outstanding options are to be effected in a manner which shall preclude
the enlargement or dilution of rights and benefits under such options. The
adjustments determined by the Plan Administrator shall be final, binding and
conclusive.

                          DISCRETIONARY OPTION GRANT PROGRAM


    I.   OPTION TERMS

         Each option shall be evidenced by one or more documents in the form
approved by the Plan Administrator; PROVIDED, however, that each such document
shall comply with the terms specified below.  Each document evidencing an
Incentive Option shall, in addition, be subject to the provisions of the Plan
applicable to such options.

         A.   EXERCISE PRICE.

              1.   The exercise price per share shall be fixed by the Plan
Administrator but shall not be less than eighty-five percent (85%) of the Fair
Market Value per share of Common Stock on the option grant date.

              2.   The exercise price shall become immediately due upon
exercise of the option and shall, subject to the provisions of Section I of
Article Six and the documents evidencing the option, be payable in one or more
of the forms specified below:

                (i)     cash or check made payable to the Corporation,

               (ii)     shares of Common Stock held for the requisite
    period necessary to avoid a charge to the Corporation's earnings for
    financial reporting purposes and valued at Fair Market Value on the
    Exercise Date, or

              (iii)     to the extent the option is exercised for vested
    shares, through a special sale and remittance procedure pursuant to
    which the Optionee shall concurrently provide irrevocable written
    instructions to (a) a Corporation-designated brokerage firm to effect
    the immediate sale of the purchased shares and remit to the
    Corporation, out of the sale proceeds available on the settlement
    date, sufficient funds to cover the aggregate exercise price payable
    for the purchased shares plus all applicable Federal, state and local
    income and employment taxes required to be withheld by the Corporation
    by reason of such exercise and (b) the Corporation to deliver the
    certificates for the purchased shares directly to such brokerage firm
    in order to complete the sale.

         Except to the extent such sale and remittance procedure is utilized,
payment of the exercise price for the purchased shares must be made on the
Exercise Date.


                                          6.

<PAGE>

         B.   EXERCISE AND TERM OF OPTIONS.  Each option shall be exercisable
at such time or times, during such period and for such number of shares as shall
be determined by the Plan Administrator and set forth in the documents
evidencing the option.  However, no option shall have a term in excess of ten
(10) years measured from the option grant date.

         C.   EFFECT OF TERMINATION OF SERVICE.

              1.   The following provisions shall govern the exercise of any
options held by the Optionee at the time of cessation of Service or death:

                (i)     Any option outstanding at the time of the
    Optionee's cessation of Service for any reason shall remain
    exercisable for such period of time thereafter as shall be determined
    by the Plan Administrator and set forth in the documents evidencing
    the option, but no such option shall be exercisable after the
    expiration of the option term.

               (ii)     Any option exercisable in whole or in part by the
    Optionee at the time of death may be subsequently exercised by the
    personal representative of the Optionee's estate or by the person or
    persons to whom the option is transferred pursuant to the Optionee's
    will or in accordance with the laws of descent and distribution.

              (iii)     Should the Optionee's Service be terminated for
    Misconduct, then all outstanding options held by the Optionee shall
    terminate immediately and cease to be outstanding.

               (iv)     During the applicable post-Service exercise
    period, the option may not be exercised in the aggregate for more than
    the number of vested shares for which the option is exercisable on the
    date of the Optionee's cessation of Service.  Upon the expiration of
    the applicable exercise period or (if earlier) upon the expiration of
    the option term, the option shall terminate and cease to be
    outstanding for any vested shares for which the option has not been
    exercised.  However, the option shall, immediately upon the Optionee's
    cessation of Service, terminate and cease to be outstanding to the
    extent the option is not otherwise at that time exercisable for vested
    shares.

              2.   The Plan Administrator shall have complete discretion,
exercisable either at the time an option is granted or at any time while the
option remains outstanding, to:

               (i)      extend the period of time for which the option is
    to remain exercisable following the Optionee's cessation of Service
    from the limited exercise period otherwise in effect for that option
    to such greater


                                          7.

<PAGE>

    period of time as the Plan Administrator shall deem appropriate, but in no
    event beyond the expiration of the option term, and/or

               (ii)     permit the option to be exercised, during the
    applicable post-Service exercise period, not only with respect to the
    number of vested shares of Common Stock for which such option is
    exercisable at the time of the Optionee's cessation of Service but
    also with respect to one or more additional installments in which the
    Optionee would have vested had the Optionee continued in Service.

         D.   STOCKHOLDER RIGHTS.  The holder of an option shall have no
stockholder rights with respect to the shares subject to the option until such
person shall have exercised the option, paid the exercise price and become a
holder of record of the purchased shares.

         E.   REPURCHASE RIGHTS.  The Plan Administrator shall have the
discretion to grant options which are exercisable for unvested shares of Common
Stock.  Should the Optionee cease Service while holding such unvested shares,
the Corporation shall have the right to repurchase, at the exercise price paid
per share, any or all of those unvested shares.  The terms upon which such
repurchase right shall be exercisable (including the period and procedure for
exercise and the appropriate vesting schedule for the purchased shares) shall be
established by the Plan Administrator and set forth in the document evidencing
such repurchase right.

         F.   LIMITED TRANSFERABILITY OF OPTIONS.  During the lifetime of the
Optionee, Incentive Options shall be exercisable only by the Optionee and shall
not be assignable or transferable other than by will or by the laws of descent
and distribution following the Optionee's death.  However, a Non-Statutory
Option may, in connection with the Optionee's estate plan, be assigned in whole
or in part during the Optionee's lifetime to one or more members of the
Optionee's immediate family or to a trust established exclusively for one or
more such family members.  The assigned portion may only be exercised by the
person or persons who acquire a proprietary interest in the option pursuant to
the assignment. The terms applicable to the assigned portion shall be the same
as those in effect for the option immediately prior to such assignment and shall
be set forth in such documents issued to the assignee as the Plan Administrator
may deem appropriate.

  II.    INCENTIVE OPTIONS

         The terms specified below shall be applicable to all Incentive
Options.  Except as modified by the provisions of this Section II, all the
provisions of Articles One, Two and Seven shall be applicable to Incentive
Options.  Options which are specifically designated as Non-Statutory Options
when issued under the Plan shall NOT be subject to the terms of this Section II.

         A.   ELIGIBILITY.  Incentive Options may only be granted to Employees.


                                          8.

<PAGE>

         B.   EXERCISE PRICE.  The exercise price per share shall not be less
than one hundred percent (100%) of the Fair Market Value per share of Common
Stock on the option grant date.

         C.   DOLLAR LIMITATION.  The aggregate Fair Market Value of the shares
of Common Stock (determined as of the respective date or dates of grant) for
which one or more options granted to any Employee under the Plan (or any other
option plan of the Corporation or any Parent or Subsidiary) may for the first
time become exercisable as Incentive Options during any one calendar year shall
not exceed the sum of One Hundred Thousand Dollars ($100,000).  To the extent
the Employee holds two (2) or more such options which become exercisable for the
first time in the same calendar year, the foregoing limitation on the
exercisability of such options as Incentive Options shall be applied on the
basis of the order in which such options are granted.

         D.   10% STOCKHOLDER.  If any Employee to whom an Incentive Option is
granted is a 10% Stockholder, then the exercise price per share shall not be
less than one hundred ten percent (110%) of the Fair Market Value per share of
Common Stock on the option grant date, and the option term shall not exceed five
(5) years measured from the option grant date.

 III.    CORPORATE TRANSACTION/CHANGE IN CONTROL

         A.   In the event of any Corporate Transaction, each outstanding
option shall automatically accelerate so that each such option shall,
immediately prior to the effective date of the Corporate Transaction, become
fully exercisable with respect to the total number of shares of Common Stock at
the time subject to such option and may be exercised for any or all of those
shares as fully-vested shares of Common Stock.  However, an outstanding option
shall not so accelerate if and to the extent:  (i) such option is, in connection
with the Corporate Transaction, either to be assumed by the successor
corporation (or parent thereof) or to be replaced with a comparable option to
purchase shares of the capital stock of the successor corporation (or parent
thereof), (ii) such option is to be replaced with a cash incentive program of
the successor corporation which preserves the spread existing on the unvested
option shares at the time of the Corporate Transaction and provides for
subsequent payout in accordance with the same vesting schedule applicable to
those option shares or (iii) the acceleration of such option is subject to other
limitations imposed by the Plan Administrator at the time of the option grant.
The determination of option comparability under clause (i) above shall be made
by the Plan Administrator, and its determination shall be final, binding and
conclusive.

         B.   All outstanding repurchase rights shall also terminate
automatically, and the shares of Common Stock subject to those terminated rights
shall immediately vest in full, in the event of any Corporate Transaction,
except to the extent: (i) those repurchase rights are to be assigned to the
successor corporation (or parent thereof) in connection with such


                                          9.

<PAGE>

Corporate Transaction or (ii) such accelerated vesting is precluded by other
limitations imposed by the Plan Administrator at the time the repurchase right
is issued.

         C.   Immediately following the consummation of the Corporate
Transaction, all outstanding options shall terminate and cease to be
outstanding, except to the extent assumed by the successor corporation (or
parent thereof).

         D.   Each option which is assumed in connection with a Corporate
Transaction shall be appropriately adjusted, immediately after such Corporate
Transaction, to apply to the number and class of securities which would have
been issuable to the Optionee in consummation of such Corporate Transaction had
the option been exercised immediately prior to such Corporate Transaction.
Appropriate adjustments to reflect such Corporate Transaction shall also be made
to (i) the exercise price payable per share under each outstanding option,
PROVIDED the aggregate exercise price payable for such securities shall remain
the same, (ii) the maximum number and/or class of securities available for
issuance over the remaining term of the Plan and (iii) the maximum number and/or
class of securities for which any one person may be granted stock options,
separately exercisable stock appreciation rights and direct stock issuances
under the Plan per calendar year.

         E.   The Plan Administrator shall have full power and authority to
grant options under the Discretionary Option Grant Program which will
automatically accelerate in the event the Optionee's Service subsequently
terminates by reason of an Involuntary Termination within a designated period
(not to exceed eighteen (18) months) following the effective date of any
Corporate Transaction in which those options are assumed or replaced and do not
otherwise accelerate.  Any options so accelerated shall remain exercisable for
fully-vested shares until the EARLIER of (i) the expiration of the option term
or (ii) the expiration of the one (1)-year period measured from the effective
date of the Involuntary Termination.  In addition, the Plan Administrator may
provide that one or more of the Corporation's outstanding repurchase rights with
respect to shares held by the Optionee at the time of such Involuntary
Termination shall immediately terminate, and the shares subject to those
terminated repurchase rights shall accordingly vest in full.

         F.   The Plan Administrator shall have full power and authority to
grant options under the Discretionary Option Grant Program which will
automatically accelerate in the event the Optionee's Service subsequently
terminates by reason of an Involuntary Termination within a designated period
(not to exceed eighteen (18) months) following the effective date of any Change
in Control.  Each option so accelerated shall remain exercisable for
fully-vested shares until the EARLIER of (i) the expiration of the option term
or (ii) the expiration of the one (1)-year period measured from the effective
date of the Involuntary Termination.  In addition, the Plan Administrator may
provide that one or more of the Corporation's outstanding repurchase rights with
respect to shares held by the Optionee at the time of such Involuntary
Termination shall immediately terminate, and the shares subject to those
terminated repurchase rights shall accordingly vest in full.


                                         10.

<PAGE>

         G.   The portion of any Incentive Option accelerated in connection
with a Corporate Transaction or Change in Control shall remain exercisable as an
Incentive Option only to the extent the applicable One Hundred Thousand Dollar
limitation is not exceeded.  To the extent such dollar limitation is exceeded,
the accelerated portion of such option shall be exercisable as a Non-Statutory
Option under the Federal tax laws.

         H.   The outstanding options shall in no way affect the right of the
Corporation to adjust, reclassify, reorganize or otherwise change its capital or
business structure or to merge, consolidate, dissolve, liquidate or sell or
transfer all or any part of its business or assets.

  IV.    CANCELLATION AND REGRANT OF OPTIONS

         The Plan Administrator shall have the authority to effect, at any time
and from time to time, with the consent of the affected option holders, the
cancellation of any or all outstanding options under the Discretionary Option
Grant Program (including outstanding options incorporated from the Predecessor
Plan) and to grant in substitution new options covering the same or different
number of shares of Common Stock but with an exercise price per share based on
the Fair Market Value per share of Common Stock on the new grant date.

   V.    STOCK APPRECIATION RIGHTS

         A.   The Plan Administrator shall have full power and authority to
grant to selected Optionees tandem stock appreciation rights and/or limited
stock appreciation rights.

         B.   The following terms shall govern the grant and exercise of tandem
stock appreciation rights:

                (i)     One or more Optionees may be granted the right,
    exercisable upon such terms as the Plan Administrator may establish,
    to elect between the exercise of the underlying option for shares of
    Common Stock and the surrender of that option in exchange for a
    distribution from the Corporation in an amount equal to the excess of
    (a) the Fair Market Value (on the option surrender date) of the number
    of shares in which the Optionee is at the time vested under the
    surrendered option (or surrendered portion thereof) over (b) the
    aggregate exercise price payable for such shares.

               (ii)     No such option surrender shall be effective unless
    it is approved by the Plan Administrator, either at the time of the
    actual option surrender or at any earlier time.  If the surrender is
    so approved, then the distribution to which the Optionee shall be
    entitled may be made in shares of Common Stock valued at Fair Market
    Value on the option


                                         11.

<PAGE>

    surrender date, in cash, or partly in shares and partly in cash, as the
    Plan Administrator shall in its sole discretion deem appropriate.

              (iii)     If the surrender of an option is not approved by
    the Plan Administrator, then the Optionee shall retain whatever rights
    the Optionee had under the surrendered option (or surrendered portion
    thereof) on the option surrender date and may exercise such rights at
    any time prior to the LATER of (a) five (5) business days after the
    receipt of the rejection notice or (b) the last day on which the
    option is otherwise exercisable in accordance with the terms of the
    documents evidencing such option, but in no event may such rights be
    exercised more than ten (10) years after the option grant date.

         C.   The following terms shall govern the grant and exercise of
limited stock appreciation rights:

                (i)     One or more Section 16 Insiders may be granted
    limited stock appreciation rights with respect to their outstanding
    options.

               (ii)     Upon the occurrence of a Hostile Take-Over, each
    individual holding one or more options with such a limited stock
    appreciation right shall have the unconditional right (exercisable for
    a thirty (30)-day period following such Hostile Take-Over) to
    surrender each such option to the Corporation, to the extent the
    option is at the time exercisable for vested shares of Common Stock.
    In return for the surrendered option, the Optionee shall receive a
    cash distribution from the Corporation in an amount equal to the
    excess of (A) the Take-Over Price of the shares of Common Stock which
    are at the time vested under each surrendered option (or surrendered
    portion thereof) over (B) the aggregate exercise price payable for
    such shares.  Such cash distribution shall be paid within five (5)
    days following the option surrender date.

              (iii)     Neither the approval of the Plan Administrator nor
    the consent of the Board shall be required in connection with such
    option surrender and cash distribution.

               (iv)     The balance of the option (if any) shall remaining
    outstanding and exercisable in accordance with the documents
    evidencing such option.

         D.   The shares of Common Stock underlying any stock appreciation
rights exercised under this Section V shall NOT be available for subsequent
issuance under the Plan.

                        SALARY INVESTMENT OPTION GRANT PROGRAM


         I.   OPTION GRANTS

         The Primary Committee shall have the sole and exclusive authority to
determine the calendar year or years (if any) for which the Salary Investment
Option Grant Program is to be in effect and to select the Section 16 Insiders
and other highly compensated Employees eligible to participate in the Salary
Investment Option Grant Program for those calendar year or years.  Each selected
individual who elects to participate in the Salary Investment Option Grant
Program must, prior to the start of each calendar year of participation, file
with the Plan Administrator (or its designate) an irrevocable authorization
directing the Corporation to reduce his or her base salary for that calendar
year by an amount not less than Ten Thousand Dollars ($10,000.00) nor more than
Fifty Thousand Dollars ($50,000.00).  The Primary Committee shall have complete
discretion to determine whether or not to approve the filed authorization in
whole or in part.  To the extent the Primary Committee approves the
authorization, the individual who filed that authorization shall be granted an
option under the Salary Investment Grant Program on or before the last trading
day in January of the calendar year for which the salary reduction is to be in
effect.  All grants under the Salary Investment Option Grant Program shall be at
the sole discretion of the Primary Committee.

  II.    OPTION TERMS

         Each option shall be a Non-Statutory Option evidenced by one or more
documents in the form approved by the Plan Administrator; PROVIDED, however,
that each such document shall comply with the terms specified below.

         A.   EXERCISE PRICE.

              1.   The exercise price per share shall be thirty-three and
one-third percent (33-1/3%) of the Fair Market Value per share of Common Stock
on the option grant date.

              2.   The exercise price shall become immediately due upon
exercise of the option and shall be payable in one or more of the alternative
forms authorized under the Discretionary Option Grant Program.  Except to the
extent the sale and remittance procedure specified thereunder is utilized,
payment of the exercise price for the purchased shares must be made on the
Exercise Date.


                                         13.

<PAGE>

         B.   NUMBER OF OPTION SHARES.  The number of shares of Common Stock
subject to the option shall be determined pursuant to the following formula
(rounded down to the nearest whole number):

              X = A DIVIDED BY (B x 66-2/3%), where

              X is the number of option shares,

              A is the dollar amount of the approved reduction in the
              Optionee's base salary for the calendar year, and

              B is the Fair Market Value per share of Common Stock on the
              option grant date.

         C.   EXERCISE AND TERM OF OPTIONS.  The option shall become
exercisable in a series of twelve (12) successive equal monthly installments
upon the Optionee's completion of each calendar month of Service in the calendar
year for which the salary reduction is in effect.  Each option shall have a
maximum term of ten (10) years measured from the option grant date.

         D.   EFFECT OF TERMINATION OF SERVICE.  Should the Optionee cease
Service for any reason while holding one or more options under this Article
Three, then each such option shall remain exercisable, for any or all of the
shares for which the option is exercisable at the time of such cessation of
Service, until the EARLIER of (i) the expiration of the ten (10)-year option
term or (ii) the expiration of the three (3)-year period measured from the date
of such cessation of Service.  Should the Optionee die while holding one or more
options under this Article Three, then each such option may be exercised, for
any or all of the shares for which the option is exercisable at the time of the
Optionee's cessation of Service (less any shares subsequently purchased by
Optionee prior to death), by the personal representative of the Optionee's
estate or by the person or persons to whom the option is transferred pursuant to
the Optionee's will or in accordance with the laws of descent and distribution.
Such right of exercise shall lapse, and the option shall terminate, upon the
EARLIER of (i) the expiration of the ten (10)-year option term or (ii) the three
(3)-year period measured from the date of the Optionee's cessation of Service.
However, the option shall, immediately upon the Optionee's cessation of Service
for any reason, terminate and cease to remain outstanding with respect to any
and all shares of Common Stock for which the option is not otherwise at that
time exercisable.

 III.    CORPORATE TRANSACTION/CHANGE IN CONTROL

         A.   In the event of any Corporate Transaction while the Optionee
remains in Service, each outstanding option held by such Optionee under this
Salary Investment Option Grant Program shall automatically accelerate so that
each such option shall, immediately prior to the effective date of the Corporate
Transaction, become fully


                                         14.

<PAGE>

exercisable with respect to the total number of shares of Common Stock at the
time subject to such option and may be exercised for any or all of those shares
as fully-vested shares of Common Stock.  Each such outstanding option shall be
assumed by the successor corporation (or parent thereof) in the Corporate
Transaction and shall remain exercisable for the fully-vested shares until the
EARLIER of (i) the expiration of the ten (10)-year option term or (ii) the
expiration of the three (3)-year period measured from the date of the Optionee's
cessation of Service.

         B.   In the event of a Change in Control while the Optionee remains in
Service, each outstanding option held by such Optionee under this Salary
Investment Option Grant Program shall automatically accelerate so that each such
option shall immediately become fully exercisable with respect to the total
number of shares of Common Stock at the time subject to such option and may be
exercised for any or all of those shares as fully-vested shares of Common Stock.
The option shall remain so exercisable until the EARLIER or (i) the expiration
of the ten (10)-year option term or (ii) the expiration of the three (3)-year
period measured from the date of the Optionee's cessation of Service.

         C.   The grant of options under the Salary Investment Option Grant
Program shall in no way affect the right of the Corporation to adjust,
reclassify, reorganize or otherwise change its capital or business structure or
to merge, consolidate, dissolve, liquidate or sell or transfer all or any part
of its business or assets.

 III.    REMAINING TERMS

         The remaining terms of each option granted under the Salary Investment
Option Grant Program shall be the same as the terms in effect for option grants
made under the Discretionary Option Grant Program.

                                STOCK ISSUANCE PROGRAM


    I.   STOCK ISSUANCE TERMS

         Shares of Common Stock may be issued under the Stock Issuance Program
through direct and immediate issuances without any intervening option grants.
Each such stock issuance shall be evidenced by a Stock Issuance Agreement which
complies with the terms specified below.

         A.   PURCHASE PRICE.

              1.   The purchase price per share shall be fixed by the Plan
Administrator, but shall not be less than one hundred percent (100%) of the Fair
Market Value per share of Common Stock on the issuance date.

              2.   Subject to the provisions of Section I of Article Seven,
shares of Common Stock may be issued under the Stock Issuance Program for any of
the following items of consideration which the Plan Administrator may deem
appropriate in each individual instance:

                (i)     cash or check made payable to the Corporation, or

               (ii)     past services rendered to the Corporation (or any
    Parent or Subsidiary).

         B.   VESTING PROVISIONS.

              1.   Shares of Common Stock issued under the Stock Issuance
Program may, in the discretion of the Plan Administrator, be fully and
immediately vested upon issuance or may vest in one or more installments over
the Participant's period of Service or upon attainment of specified performance
objectives.  The elements of the vesting schedule applicable to any unvested
shares of Common Stock issued under the Stock Issuance Program, namely:

                (i)     the Service period to be completed by the
    Participant or the performance objectives to be attained,

               (ii)     the number of installments in which the shares are
    to vest,


                                         16.

<PAGE>

              (iii)     the interval or intervals (if any) which are to
    lapse between installments, and

               (iv)     the effect which death, Permanent Disability or
    other event designated by the Plan Administrator is to have upon the
    vesting schedule,

shall be determined by the Plan Administrator and incorporated into the Stock
Issuance Agreement.

              2.   Any new, substituted or additional securities or other
property (including money paid other than as a regular cash dividend) which the
Participant may have the right to receive with respect to the Participant's
unvested shares of Common Stock by reason of any stock dividend, stock split,
recapitalization, combination of shares, exchange of shares or other change
affecting the outstanding Common Stock as a class without the Corporation's
receipt of consideration shall be issued subject to (i) the same vesting
requirements applicable to the Participant's unvested shares of Common Stock and
(ii) such escrow arrangements as the Plan Administrator shall deem appropriate.

              3.   The Participant shall have full stockholder rights with
respect to any shares of Common Stock issued to the Participant under the Stock
Issuance Program, whether or not the Participant's interest in those shares is
vested.  Accordingly, the Participant shall have the right to vote such shares
and to receive any regular cash dividends paid on such shares.

              4.   Should the Participant cease to remain in Service while
holding one or more unvested shares of Common Stock issued under the Stock
Issuance Program or should the performance objectives not be attained with
respect to one or more such unvested shares of Common Stock, then those shares
shall be immediately surrendered to the Corporation for cancellation, and the
Participant shall have no further stockholder rights with respect to those
shares.  To the extent the surrendered shares were previously issued to the
Participant for consideration paid in cash or cash equivalent (including the
Participant's purchase-money indebtedness), the Corporation shall repay to the
Participant the cash consideration paid for the surrendered shares and shall
cancel the unpaid principal balance of any outstanding purchase-money note of
the Participant attributable to the surrendered shares.

              5.   The Plan Administrator may in its discretion waive the
surrender and cancellation of one or more unvested shares of Common Stock which
would otherwise occur upon the cessation of the Participant's Service or the
non-attainment of the performance objectives applicable to those shares.  Such
waiver shall result in the immediate


                                         17.

<PAGE>

vesting of the Participant's interest in the shares as to which the waiver
applies.  Such waiver may be effected at any time, whether before or after the
Participant's cessation of Service or the attainment or non-attainment of the
applicable performance objectives.

  II.    CORPORATE TRANSACTION/CHANGE IN CONTROL

         A.   All of the Corporation's outstanding repurchase/cancellation
rights under the Stock Issuance Program shall terminate automatically, and all
the shares of Common Stock subject to those terminated rights shall immediately
vest in full, in the event of any Corporate Transaction, except to the extent
(i) those repurchase/cancellation rights are to be assigned to the successor
corporation (or parent thereof) in connection with such Corporate Transaction or
(ii) such accelerated vesting is precluded by other limitations imposed in the
Stock Issuance Agreement.

         B.   The Plan Administrator shall have the discretionary authority,
exercisable either at the time the unvested shares are issued or any time while
the Corporation's repurchase/cancellation rights remain outstanding under the
Stock Issuance Program, to provide that those rights shall automatically
terminate in whole or in part, and the shares of Common Stock subject to those
terminated rights shall immediately vest, in the event the Participant's Service
should subsequently terminate by reason of an Involuntary Termination within a
designated period (not to exceed eighteen (18) months) following the effective
date of any Corporate Transaction in which those repurchase/cancellation rights
are assigned to the successor corporation (or parent thereof).

         C.   The Plan Administrator shall have the discretionary authority,
exercisable either at the time the unvested shares are issued or any time while
the Corporation's repurchase/cancellation rights remain outstanding under the
Stock Issuance Program, to provide that those rights shall automatically
terminate in whole or in part, and the shares of Common Stock subject to those
terminated rights shall immediately vest, in the event the Participant's Service
should subsequently terminate by reason of an Involuntary Termination within a
designated period (not to exceed eighteen (18) months) following the effective
date of any Change in Control.

 III.    SHARE ESCROW/LEGENDS

         Unvested shares may, in the Plan Administrator's discretion, be held
in escrow by the Corporation until the Participant's interest in such shares
vests or may be issued directly to the Participant with restrictive legends on
the certificates evidencing those unvested shares.

                            AUTOMATIC OPTION GRANT PROGRAM


   I.    OPTION TERMS

         A.   GRANT DATES.  Option grants shall be made on the dates specified
below:

              1.   Each individual who is first elected or appointed as a
non-employee Board member at any time after June 30, 1996 shall automatically be
granted, on the date of such initial election or appointment, a Non-Statutory
Option to purchase 20,000 shares of Common Stock, provided that individual has
not previously been in the employ of the Corporation or any Parent or
Subsidiary.

              2.   On the date of each Annual Stockholders Meeting held after
the Underwriting Date, each individual who is to continue to serve as an
Eligible Director, whether or not that individual is standing for re-election to
the Board at that particular Annual Meeting, shall automatically be granted a
Non-Statutory Option to purchase 6,000  shares of Common Stock, provided such
individual has served as a non-employee Board member for at least six (6)
months.  There shall be no limit on the number of such 6,000-share option grants
any one Eligible Director may receive over his or her period of Board service,
and non-employee Board members who have previously been in the employ of the
Corporation (or any Parent or Subsidiary) or who first joined the Board prior to
July 1, 1996 shall be eligible to receive one or more such annual option grants
over their period of continued Board service.

         B.   EXERCISE PRICE.

              1.   The exercise price per share shall be equal to one hundred
percent (100%) of the Fair Market Value per share of Common Stock on the option
grant date.

              2.   The exercise price shall be payable in one or more of the
alternative forms authorized under the Discretionary Option Grant Program.
Except to the extent the sale and remittance procedure specified thereunder is
utilized, payment of the exercise price for the purchased shares must be made on
the Exercise Date.

         C.   OPTION TERM.  Each option shall have a term of ten (10) years
measured from the option grant date.


                                         19.

<PAGE>

         D.   EXERCISE AND VESTING OF OPTIONS.  Each option shall be
immediately exercisable for any or all of the option shares.  However, any
shares purchased under the option shall be subject to repurchase by the
Corporation, at the exercise price paid per share, upon the Optionee's cessation
of Board service prior to vesting in those shares.  Each grant shall vest, and
the Corporation's repurchase right shall lapse, as follows:  (i) one-third of
the option shares shall vest upon the Optionee's completion of one (1) year of
Board service measured from the option grant date and (ii) the balance of the
option shares shall vest in a series of twenty-four (24) successive equal
monthly installments upon the Optionee's completion of each additional month of
Board service over the twenty-four (24)-month period measured from the first
anniversary of such grant date.

         E.   TERMINATION OF BOARD SERVICE.  The following provisions shall
govern the exercise of any options held by the Optionee at the time the Optionee
ceases to serve as a Board member:

                (i)     The Optionee (or, in the event of Optionee's
    death, the personal representative of the Optionee's estate or the
    person or persons to whom the option is transferred pursuant to the
    Optionee's will or in accordance with the laws of descent and
    distribution) shall have a twelve (12)-month period following the date
    of such cessation of Board service in which to exercise each such
    option.

               (ii)     During the twelve (12)-month exercise period, the
    option may not be exercised in the aggregate for more than the number
    of vested shares of Common Stock for which the option is exercisable
    at the time of the Optionee's cessation of Board service.

              (iii)     Should the Optionee cease to serve as a Board
    member by reason of death or Permanent Disability, then all shares at
    the time subject to the option shall immediately vest so that such
    option may, during the twelve (12)-month exercise period following
    such cessation of Board service, be exercised for all or any portion
    of those shares as fully-vested shares of Common Stock.

               (iv)     In no event shall the option remain exercisable
    after the expiration of the option term.  Upon the expiration of the
    twelve (12)-month exercise period or (if earlier) upon the expiration
    of the option term, the option shall terminate and cease to be
    outstanding for any vested shares for which the option has not been
    exercised.  However, the option shall, immediately upon the Optionee's
    cessation of Board service for any reason other than death or
    Permanent Disability, terminate and cease to be outstanding to the
    extent the option is not otherwise at that time exercisable for vested
    shares.


                                         20.

<PAGE>

  II.    SPECIAL CORPORATE EVENTS

         A.   In the event of any Corporate Transaction, the shares of Common
Stock at the time subject to each outstanding option but not otherwise vested
shall automatically vest in full so that each such option shall, immediately
prior to the effective date of the Corporate Transaction, become fully
exercisable for all of the shares of Common Stock at the time subject to such
option and may be exercised for all or any portion of those shares as
fully-vested shares of Common Stock.  Immediately following the consummation of
the Corporate Transaction, each automatic option grant shall terminate and cease
to be outstanding, except to the extent assumed by the successor corporation (or
parent thereof).

         B.   In connection with any Change in Control, the shares of Common
Stock at the time subject to each outstanding option but not otherwise vested
shall automatically vest in full so that each such option shall, immediately
prior to the effective date of the Change in Control, become fully exercisable
for all of the shares of Common Stock at the time subject to such option and may
be exercised for all or any portion of those shares as fully-vested shares of
Common Stock.  Each such option shall remain exercisable for such fully-vested
option shares until the expiration or sooner termination of the option term or
the surrender of the option in connection with a Hostile Take-Over.

         C.   Upon the occurrence of a Hostile Take-Over, the Optionee shall
have a thirty (30)-day period in which to surrender to the Corporation each of
his or her outstanding automatic option grants.  The Optionee shall in return be
entitled to a cash distribution from the Corporation in an amount equal to the
excess of (i) the Take-Over Price of the shares of Common Stock at the time
subject to each surrendered option (whether or not the Optionee is otherwise at
the time vested in those shares) over (ii) the aggregate exercise price payable
for such shares.  Such cash distribution shall be paid within five (5) days
following the surrender of the option to the Corporation.  No approval or
consent of the Board or any Plan Administrator shall be required in connection
with such option surrender and cash distribution.

         D.   Each option which is assumed in connection with a Corporate
Transaction shall be appropriately adjusted, immediately after such Corporate
Transaction, to apply to the number and class of securities which would have
been issuable to the Optionee in consummation of such Corporate Transaction had
the option been exercised immediately prior to such Corporate Transaction.
Appropriate adjustments shall also be made to the exercise price payable per
share under each outstanding option, PROVIDED the aggregate exercise price
payable for such securities shall remain the same.

         E.   The grant of options under the Automatic Option Grant Program
shall in no way affect the right of the Corporation to adjust, reclassify,
reorganize or otherwise change its capital or business structure or to merge,
consolidate, dissolve, liquidate or sell or transfer all or any part of its
business or assets.

                          DIRECTOR FEE OPTION GRANT PROGRAM

         I.   OPTION GRANTS

         Each non-employee Board member may elect to apply all or any portion
of the annual retainer fee otherwise payable in cash for his or her service on
the Board to the acquisition of a special option grant under this Director Fee
Option Grant Program.  Such election must be filed with the Corporation's Chief
Financial Officer prior to the first day of the calendar year for which the
annual retainer fee which is the subject of that election is otherwise payable.
Each non-employee Board member who files such a timely election shall
automatically be granted an option under this Director Fee Option Grant Program
on the first trading day in January in the calendar year for which the annual
retainer fee which is the subject of that election would otherwise be payable.

  II.    OPTION TERMS

         Each option shall be a Non-Statutory Option governed by the terms and
conditions specified below.

         A.   EXERCISE PRICE.

              1.   The exercise price per share shall be thirty-three and
one-third percent (33-1/3%) of the Fair Market Value per share of Common Stock
on the option grant date.

              2.   The exercise price shall become immediately due upon
exercise of the option and shall be payable in one or more of the alternative
forms authorized under the Discretionary Option Grant Program.  Except to the
extent the sale and remittance procedure specified thereunder is utilized,
payment of the exercise price for the purchased shares must be made on the
Exercise Date.

         B.   NUMBER OF OPTION SHARES.  The number of shares of Common Stock
subject to the option shall be determined pursuant to the following formula
(rounded down to the nearest whole number):

              X = A DIVIDED BY (B x 66-2/3%), where

              X is the number of option shares,

              A is the portion of the annual retainer fee subject to the
              non-employee Board member's election, and


                                         23.

<PAGE>

              B is the Fair Market Value per share of Common Stock on the
              option grant date.

         C.   EXERCISE AND TERM OF OPTIONS.  The option shall become
exercisable for fifty percent (50%) of the option shares upon the Optionee's
completion of six (6) months of Board service in the calendar year for which his
or her election under this Director Fee Option Grant Program is in effect, and
the balance of the option shares shall become exercisable in a series of six (6)
successive equal monthly installments upon the Optionee's completion of each
additional month of Board service during that calendar year.  Each option shall
have a maximum term of ten (10) years measured from the option grant date.

         D.   TERMINATION OF BOARD SERVICE.  Should the Optionee cease Board
service for any reason (other than death or Permanent Disability) while holding
one or more options under this Director Fee Option Grant Program, then each such
option shall remain exercisable, for any or all of the shares for which the
option is exercisable at the time of such cessation of Board service, until the
EARLIER of (i) the expiration of the ten (10)-year option term or (ii) the
expiration of the three (3)-year period measured from the date of such cessation
of Board service.  However, each option held by the Optionee under this Director
Fee Option Grant Program at the time of his or her cessation of Board service
shall immediately terminate and cease to remain outstanding with respect to any
and all shares of Common Stock for which the option is not otherwise at that
time exercisable.

         E.   DEATH OR PERMANENT DISABILITY.  Should the Optionee's service as
a Board member cease by reason of death or Permanent Disability, then each
option held by such Optionee under this Director Fee Option Grant Program shall
immediately become exercisable for all the shares of Common Stock at the time
subject to that option, and the option may be exercised for any or all of those
shares as fully-vested shares until the EARLIER of (i) the expiration of the ten
(10)-year option term or (ii) the expiration of the three (3)-year period
measured from the date of such cessation of Board service.

         Should the Optionee die after cessation of Board service but while
holding one or more options under this Director Fee Option Grant Program, then
each such option may be exercised, for any or all of the shares for which the
option is exercisable at the time of the Optionee's cessation of Board service
(less any shares subsequently purchased by Optionee prior to death), by the
personal representative of the Optionee's estate or by the person or persons to
whom the option is transferred pursuant to the Optionee's will or in accordance
with the laws of descent and distribution.  Such right of exercise shall lapse,
and the option shall terminate, upon the EARLIER of (i) the expiration of the
ten (10)-year option term or (ii) the three (3)-year period measured from the
date of the Optionee's cessation of Board service.


                                         24.

 III.    CORPORATE TRANSACTION/CHANGE IN CONTROL

         A.   In the event of any Corporate Transaction while the Optionee
remains a Board member, each outstanding option held by such Optionee under this
Director Fee Option Grant Program shall automatically accelerate so that each
such option shall, immediately prior to the effective date of the Corporate
Transaction, become fully exercisable with respect to the total number of shares
of Common Stock at the time subject to such option and may be exercised for any
or all of those shares as fully-vested shares of Common Stock.  Each such
outstanding option shall be assumed by the successor corporation (or parent
thereof) in the Corporate Transaction and shall remain exercisable for the
fully-vested shares until the EARLIER of (i) the expiration of the ten (10)-year
option term or (ii) the expiration of the three (3)-year period measured from
the date of the Optionee's cessation of Board service.

         B.   In the event of a Change in Control while the Optionee remains in
Service, each outstanding option held by such Optionee under this Director Fee
Option Grant Program shall automatically accelerate so that each such option
shall immediately become fully exercisable with respect to the total number of
shares of Common Stock at the time subject to such option and may be exercised
for any or all of those shares as fully-vested shares of Common Stock.  The
option shall remain so exercisable until the EARLIER or (i) the expiration of
the ten (10)-year option term or (ii) the expiration of the three (3)-year
period measured from the date of the Optionee's cessation of Service.

         C.   Upon the occurrence of a Hostile Take-Over, the Optionee shall
have a thirty (30)-day period in which to surrender to the Corporation each of
his or her outstanding automatic option grants.  The Optionee shall in return be
entitled to a cash distribution from the Corporation in an amount equal to the
excess of (i) the Take-Over Price of the shares of Common Stock at the time
subject to each surrendered option (whether or not the Optionee is otherwise at
the time vested in those shares) over (ii) the aggregate exercise price payable
for such shares.  Such cash distribution shall be paid within five (5) days
following the surrender of the option to the Corporation.  No approval or
consent of the Board or any Plan Administrator shall be required in connection
with such option surrender and cash distribution.

         D.   The grant of options under the Director Fee Option Grant Program
shall in no way affect the right of the Corporation to adjust, reclassify,
reorganize or otherwise change its capital or business structure or to merge,
consolidate, dissolve, liquidate or sell or transfer all or any part of its
business or assets.

  IV.    REMAINING TERMS

         The remaining terms of each option granted under this Director Fee
Option Grant Program shall be the same as the terms in effect for option grants

                                    MISCELLANEOUS


   I.    FINANCING

         The Plan Administrator may permit any Optionee or Participant to pay
the option exercise price under the Discretionary Option Grant Program or the
purchase price of shares issued under the Stock Issuance Program by delivering a
full-recourse, interest bearing promissory note payable in one or more
installments.  The terms of any such promissory note (including the interest
rate and the terms of repayment) shall be established by the Plan Administrator
in its sole discretion.  In no event may the maximum credit available to the
Optionee or Participant exceed the sum of (i) the aggregate option exercise
price or purchase price payable for the purchased shares plus (ii) any Federal,
state and local income and employment tax liability incurred by the Optionee or
the Participant in connection with the option exercise or share purchase.

  II.    TAX WITHHOLDING

         A.   The Corporation's obligation to deliver shares of Common Stock
upon the exercise of options or the issuance or vesting of such shares under the
Plan shall be subject to the satisfaction of all applicable Federal, state and
local income and employment tax withholding requirements.

         B.   The Plan Administrator may, in its discretion, provide any or all
holders of Non-Statutory Options or unvested shares of Common Stock under the
Plan (other than the options granted or the shares issued under the Automatic
Option Grant or Director Fee Option Grant Program) with the right to use shares
of Common Stock in satisfaction of all or part of the Taxes incurred by such
holders in connection with the exercise of their options or the vesting of their
shares.  Such right may be provided to any such holder in either or both of the
following formats:

              STOCK WITHHOLDING:  The election to have the Corporation
withhold, from the shares of Common Stock otherwise issuable upon the exercise
of such Non-Statutory Option or the vesting of such shares, a portion of those
shares with an aggregate Fair Market Value equal to the percentage of the Taxes
(not to exceed one hundred percent (100%)) designated by the holder.

              STOCK DELIVERY:  The election to deliver to the Corporation, at
the time the Non-Statutory Option is exercised or the shares vest, one or more
shares of Common Stock previously acquired by such holder (other than in
connection with the option exercise


                                         26.

<PAGE>

or share vesting triggering the Taxes) with an aggregate Fair Market Value equal
to the percentage of the Taxes (not to exceed one hundred percent (100%))
designated by the holder.

 III.    EFFECTIVE DATE AND TERM OF THE PLAN

         A.   The Plan shall become effective immediately upon the Plan
Effective Date.   However, the Salary Investment Option Grant Program shall not
be implemented until such time as the Primary Committee may deem appropriate.
Options may be granted under the Discretionary Option Grant or Automatic Option
Grant Program at any time on or after the Plan Effective Date.  However, no
options granted under the Plan may be exercised, and no shares shall be issued
under the Plan, until the Plan is approved by the Corporation's stockholders.
If such stockholder approval is not obtained within twelve (12) months after the
Plan Effective Date, then all options previously granted under this Plan shall
terminate and cease to be outstanding, and no further options shall be granted
and no shares shall be issued under the Plan.

         B.   The Plan shall serve as the successor to the Predecessor Plan,
and no further option grants or direct stock issuances shall be made under the
Predecessor Plan after the Section 12(g) Registration Date.   All options
outstanding under the Predecessor Plan on the Section 12(g) Registration Date
shall be incorporated into the Plan at that time and shall be treated as
outstanding options under the Plan.  However, each outstanding option so
incorporated shall continue to be governed solely by the terms of the documents
evidencing such option, and no provision of the Plan shall be deemed to affect
or otherwise modify the rights or obligations of the holders of such
incorporated options with respect to their acquisition of shares of Common
Stock.

         C.   One or more provisions of the Plan, including (without
limitation) the option/vesting acceleration provisions of Article Two relating
to Corporate Transactions and Changes in Control, may, in the Plan
Administrator's discretion, be extended to one or more options incorporated from
the Predecessor Plan which do not otherwise contain such provisions.

         D.   The Plan shall terminate upon the EARLIEST of (i) June 30, 2006,
(ii) the date on which all shares available for issuance under the Plan shall
have been issued as fully-vested shares or (iii) the termination of all
outstanding options in connection with a Corporate Transaction.  Upon such plan
termination, all outstanding option grants and unvested stock issuances shall
thereafter continue to have force and effect in accordance with the provisions
of the documents evidencing such grants or issuances.


                                         27.

<PAGE>

  IV.    AMENDMENT OF THE PLAN

         A.   The Board shall have complete and exclusive power and authority
to amend or modify the Plan in any or all respects.  However, no such amendment
or modification shall adversely affect the rights and obligations with respect
to stock options or unvested stock issuances at the time outstanding under the
Plan unless the Optionee or the Participant consents to such amendment or
modification. In addition, certain amendments may require stockholder approval
pursuant to applicable laws or regulations.

         B.   Options to purchase shares of Common Stock may be granted under
the Discretionary Option Grant and Salary Investment Option Grant Programs
and shares of Common Stock may be issued under the Stock Issuance Program that
are in each instance in excess of the number of shares then available for
issuance under the Plan, provided any excess shares actually issued under those
programs shall be held in escrow until there is obtained stockholder approval of
an amendment sufficiently increasing the number of shares of Common Stock
available for issuance under the Plan.  If such stockholder approval is not
obtained within twelve (12) months after the date the first such excess
issuances are made, then (i) any unexercised options granted on the basis of
such excess shares shall terminate and cease to be outstanding and (ii) the
Corporation shall promptly refund to the Optionees and the Participants the
exercise or purchase price paid for any excess shares issued under the Plan and
held in escrow, together with interest (at the applicable Short Term Federal
Rate) for the period the shares were held in escrow, and such shares shall
thereupon be automatically cancelled and cease to be outstanding.

   V.    USE OF PROCEEDS

         Any cash proceeds received by the Corporation from the sale of shares
of Common Stock under the Plan shall be used for general corporate purposes.

  VI.    REGULATORY APPROVALS

         A.   The implementation of the Plan, the granting of any stock option
under the Plan and the issuance of any shares of Common Stock (i) upon the
exercise of any granted option or (ii) under the Stock Issuance Program shall be
subject to the Corporation's procurement of all approvals and permits required
by regulatory authorities having jurisdiction over the Plan, the stock options
granted under it and the shares of Common Stock issued pursuant to it.

         B.   No shares of Common Stock or other assets shall be issued or
delivered under the Plan unless and until there shall have been compliance with
all applicable requirements of Federal and state securities laws, including the
filing and effectiveness of


                                         28.

the Form S-8 registration statement for the shares of Common Stock issuable
under the Plan, and all applicable listing requirements of any stock exchange
(or the Nasdaq National Market, if applicable) on which Common Stock is then
listed for trading.

 VII.    NO EMPLOYMENT/SERVICE RIGHTS

         Nothing in the Plan shall confer upon the Optionee or the Participant
any right to continue in Service for any period of specific duration or
interfere with or otherwise restrict in any way the rights of the Corporation
(or any Parent or Subsidiary employing or retaining such person) or of the
Optionee or the Participant, which rights are hereby expressly reserved by each,
to terminate such person's Service at any time for any reason, with or without
cause.

                         ADVANCED FIBRE COMMUNICATIONS, INC.
                                STOCK OPTION AGREEMENT



RECITALS


    A.   The Board has adopted the Plan for the purpose of retaining the
services of selected Employees, non-employee members of the Board or of the
board of directors of any Parent or Subsidiary and consultants and other
independent advisors who provide services to the Corporation (or any Parent or
Subsidiary).

    B.   Optionee is to render valuable services to the Corporation (or a
Parent or Subsidiary), and this Agreement is executed pursuant to, and is
intended to carry out the purposes of, the Plan in connection with the
Corporation's grant of an option to Optionee.

    C.   All capitalized terms in this Agreement shall have the meaning
assigned to them in the attached Appendix.

         NOW, THEREFORE, it is hereby agreed as follows:

         1.   GRANT OF OPTION.  The Corporation hereby grants to Optionee, as
of the Grant Date, an option to purchase up to the number of Option Shares
specified in the Grant Notice.  The Option Shares shall be purchasable from time
to time during the option term specified in Paragraph 2 at the Exercise Price.

         2.   OPTION TERM.  This option shall have a term of ten (10) years
measured from the Grant Date and shall accordingly expire at the close of
business on the Expiration Date, unless sooner terminated in accordance with
Paragraph 5 or 6.

         3.   LIMITED TRANSFERABILITY.  This option shall be neither
transferable nor assignable by Optionee other than by will or by the laws of
descent and distribution following Optionee's death and may be exercised, during
Optionee's lifetime, only by Optionee.  However, if this option is designated a
Non-Statutory Option in the Grant Notice, then this option may, in connection
with the Optionee's estate plan, be assigned in whole or in part during
Optionee's lifetime to one or more members of the Optionee's immediate family or
to a trust established for the exclusive benefit of one or more such family
members.  The assigned portion shall be exercisable only by the person or
persons who acquire a proprietary interest in the option pursuant to such
assignment.  The terms applicable to the assigned portion shall be the same as
those in effect for this option immediately prior to such assignment and shall
be set forth in such documents issued to the assignee as the Plan Administrator
may deem appropriate.


<PAGE>

         4.   DATES OF EXERCISE.  This option shall become exercisable for the
Option Shares in one or more installments as specified in the Grant Notice.  As
the option becomes exercisable for such installments, those installments shall
accumulate and the option shall remain exercisable for the accumulated
installments until the Expiration Date or sooner termination of the option term
under Paragraph 5 or 6.

         5.   CESSATION OF SERVICE.  The option term specified in Paragraph 2
shall terminate (and this option shall cease to be outstanding) prior to the
Expiration Date should any of the following provisions become applicable:

                (i)     Should Optionee cease to remain in Service for any
    reason (other than death, Permanent Disability or Misconduct) while
    this option is outstanding, then Optionee shall have a period of three
    (3) months (commencing with the date of such cessation of Service)
    during which to exercise this option, but in no event shall this
    option be exercisable at any time after the Expiration Date.

               (ii)     Should Optionee die while this option is outstanding,
    then the personal representative of Optionee's estate or the person or
    persons to whom the option is transferred pursuant to Optionee's will or in
    accordance with the laws of descent and distribution shall have the right
    to exercise this option.  Such right shall lapse, and this option shall
    cease to be outstanding, upon the EARLIER of (A) the expiration of the
    twelve (12)- month period measured from the date of Optionee's death or (B)
    the Expiration Date.

              (iii)     Should Optionee cease Service by reason of Permanent
    Disability while this option is outstanding, then Optionee shall have a
    period of twelve (12) months (commencing with the date of such cessation of
    Service) during which to exercise this option.  In no event shall this
    option be exercisable at any time after the Expiration Date.

               (iv)     During the limited period of post-Service
    exercisability, this option may not be exercised in the aggregate for more
    than the number of vested Option Shares for which the option is exercisable
    at the time of Optionee's cessation of Service.  Upon the expiration of
    such limited exercise period or (if earlier) upon the Expiration Date, this
    option shall terminate and cease to be outstanding for any vested Option
    Shares for which the option has not been exercised.  However, this option
    shall, immediately upon Optionee's cessation of Service for any reason,
    terminate and cease to be outstanding with respect to any Option Shares in
    which Optionee is not otherwise at that time vested or for which this
    option is not otherwise at that time exercisable.


                                          2.

<PAGE>

                (v)     Should Optionee's Service be terminated for Misconduct,
    then this option shall terminate immediately and cease to remain
    outstanding.

         6.   SPECIAL ACCELERATION OF OPTION.

              (a)  This option, to the extent outstanding at the time of a
Corporate Transaction but not otherwise fully exercisable, shall automatically
accelerate so that this option shall, immediately prior to the effective date of
the Corporate Transaction, become exercisable for all of the Option Shares at
the time subject to this option and may be exercised for any or all of those
Option Shares as fully-vested shares of Common Stock.  No such acceleration of
this option, however, shall occur if and to the extent: (i) this option is, in
connection with the Corporate Transaction, either to be assumed by the successor
corporation (or parent thereof) or to be replaced with a comparable option to
purchase shares of the capital stock of the successor corporation (or parent
thereof) or (ii) this option is to be replaced with a cash incentive program of
the successor corporation which preserves the spread existing on the unvested
Option Shares at the time of the Corporate Transaction (the excess of the Fair
Market Value of those Option Shares over the aggregate Exercise Price payable
for such shares) and provides for subsequent pay-out in accordance with the
option exercise/vesting schedule set forth in the Grant Notice.  The
determination of option comparability under clause (i) shall be made by the Plan
Administrator, and such determination shall be final, binding and conclusive.

              (b)  Immediately following the Corporate Transaction, this option
shall terminate and cease to be outstanding, except  to the extent assumed by
the successor corporation (or parent thereof) in connection with the Corporate
Transaction.

              (c)  If this option is assumed in connection with a Corporate
Transaction, then this option shall be appropriately adjusted, immediately after
such Corporate Transaction, to apply to the number and class of securities which
would have been issuable to Optionee in consummation of such Corporate
Transaction had the option been exercised immediately prior to such Corporate
Transaction, and appropriate adjustments shall also be made to the Exercise
Price, PROVIDED the aggregate Exercise Price shall remain the same.

              (d)  This Agreement shall not in any way affect the right of the
Corporation to adjust, reclassify, reorganize or otherwise change its capital or
business structure or to merge, consolidate, dissolve, liquidate or sell or
transfer all or any part of its business or assets.

         7.   ADJUSTMENT IN OPTION SHARES.  Should any change be made to the
Common Stock by reason of any stock split, stock dividend, recapitalization,
combination of shares, exchange of shares or other change affecting the
outstanding Common Stock as a class without the Corporation's receipt of
consideration, appropriate adjustments shall be


                                          3.

<PAGE>

made to (i) the total number and/or class of securities subject to this option
and (ii) the Exercise Price in order to reflect such change and thereby preclude
a dilution or enlargement of benefits hereunder.

         8.   STOCKHOLDER RIGHTS.  The holder of this option shall not have any
stockholder rights with respect to the Option Shares until such person shall
have exercised the option, paid the Exercise Price and become a holder of record
of the purchased shares.

         9.   MANNER OF EXERCISING OPTION.

              (a)  In order to exercise this option with respect to all or any
part of the Option Shares for which this option is at the time exercisable,
Optionee (or any other person or persons exercising the option) must take the
following actions:

                     (i)     Execute and deliver to the Corporation a Notice of
    Exercise for the Option Shares for which the option is exercised.

                    (ii)     Pay the aggregate Exercise Price for the purchased
    shares in one or more of the following forms:

                        (A)  cash or check made payable to the Corporation;

                        (B)  a promissory note payable to the Corporation, but
         only to the extent authorized by the Plan Administrator in accordance
         with Paragraph 13;

                        (C)  shares of Common Stock held by Optionee (or any
         other person or persons exercising the option) for the requisite
         period necessary to avoid a charge to the Corporation's earnings for
         financial reporting purposes and valued at Fair Market Value on the
         Exercise Date; or

                        (D)  to the extent the option is exercised for vested
         Option Shares, through a special sale and remittance procedure
         pursuant to which Optionee (or any other person or persons exercising
         the option) shall concurrently provide irrevocable written
         instructions (I) to a Corporation-designated brokerage firm to effect
         the immediate sale of the purchased shares and remit to the
         Corporation, out of the sale proceeds available on the settlement
         date, sufficient funds to cover the aggregate Exercise Price payable
         for the purchased shares plus all applicable Federal, state and local
         income and employment taxes


                                          4.

<PAGE>

         required to be withheld by the Corporation by reason of such exercise
         and (II) to the Corporation to deliver the certificates for the
         purchased shares directly to such brokerage firm in order to complete
         the sale transaction.

              Except to the extent the sale and remittance procedure is
         utilized in connection with the option exercise, payment of the
         Exercise Price must accompany the Notice of Exercise delivered to the
         Corporation in connection with the option exercise.

                   (iii)     Furnish to the Corporation appropriate
    documentation that the person or persons exercising the option (if other
    than Optionee) have the right to exercise this option.

                    (iv)     Make appropriate arrangements with the Corporation
    (or Parent or Subsidiary employing or retaining Optionee) for the
    satisfaction of all Federal, state and local income and employment tax
    withholding requirements applicable to the option exercise.

              (b)  As soon as practical after the Exercise Date, the
Corporation shall issue to or on behalf of Optionee (or any other person or
persons exercising this option) a certificate for the purchased Option Shares,
with the appropriate legends affixed thereto.

              (c)  In no event may this option be exercised for any fractional
shares.

         10.  COMPLIANCE WITH LAWS AND REGULATIONS.

              (a)  The exercise of this option and the issuance of the Option
Shares upon such exercise shall be subject to compliance by the Corporation and
Optionee with all applicable requirements of law relating thereto and with all
applicable regulations of any stock exchange (or the Nasdaq National Market, if
applicable) on which the Common Stock may be listed for trading at the time of
such exercise and issuance.

              (b)  The inability of the Corporation to obtain approval from any
regulatory body having authority deemed by the Corporation to be necessary to
the lawful issuance and sale of any Common Stock pursuant to this option shall
relieve the Corporation of any liability with respect to the non-issuance or
sale of the Common Stock as to which such approval shall not have been obtained.
The Corporation, however, shall use its best efforts to obtain all such
approvals.


                                          5.

<PAGE>

         11.  SUCCESSORS AND ASSIGNS.  Except to the extent otherwise provided
in Paragraphs 3 and 6, the provisions of this Agreement shall inure to the
benefit of, and be binding upon, the Corporation and its successors and assigns
and Optionee, Optionee's assigns and the legal representatives, heirs and
legatees of Optionee's estate.

         12.  NOTICES.  Any notice required to be given or delivered to the
Corporation under the terms of this Agreement shall be in writing and addressed
to the Corporation at its principal corporate offices.  Any notice required to
be given or delivered to Optionee shall be in writing and addressed to Optionee
at the address indicated below Optionee's signature line on the Grant Notice. 
All notices shall be deemed effective upon personal delivery or upon deposit in
the U.S. mail, postage prepaid and properly addressed to the party to be
notified.

         13.  FINANCING.  The Plan Administrator may, in its absolute
discretion and without any obligation to do so, permit Optionee to pay the
Exercise Price for the purchased Option Shares by delivering a full-recourse
promissory note payable to the Corporation.  The terms of any such promissory
note (including the interest rate, the requirements for collateral and the terms
of repayment) shall be established by the Plan Administrator in its sole
discretion.

         14.  CONSTRUCTION.  This Agreement and the option evidenced hereby are
made and granted pursuant to the Plan and are in all respects limited by and
subject to the terms of the Plan.  All decisions of the Plan Administrator with
respect to any question or issue arising under the Plan or this Agreement shall
be conclusive and binding on all persons having an interest in this option.

         15.  GOVERNING LAW.  The interpretation, performance and enforcement
of this Agreement shall be governed by the laws of the State of Delaware without
resort to that State's conflict-of-laws rules.

         16.  EXCESS SHARES.  If the Option Shares covered by this Agreement
exceed, as of the Grant Date, the number of shares of Common Stock which may
without stockholder approval be issued under the Plan, then this option shall be
void with respect to those excess shares, unless stockholder approval of an
amendment sufficiently increasing the number of shares of Common Stock issuable
under the Plan is obtained in accordance with the provisions of the Plan.

         17.  ADDITIONAL TERMS APPLICABLE TO AN INCENTIVE OPTION.  In the event
this option is designated an Incentive Option in the Grant Notice, the following
terms and conditions shall also apply to the grant:

              -    This option shall cease to qualify for favorable tax
    treatment as an Incentive Option if (and to the extent) this option is
    exercised for one or more Option Shares: (A) more than three (3) months
    after the


                                          6.

<PAGE>

    date Optionee ceases to be an Employee for any reason other than death or
    Permanent Disability or (B) more than twelve (12) months after the date
    Optionee ceases to be an Employee by reason of Permanent Disability.

              -    No installment under this option shall qualify for favorable
    tax treatment as an Incentive Option if (and to the extent) the aggregate
    Fair Market Value (determined at the Grant Date) of the Common Stock for
    which such installment first becomes exercisable hereunder would, when
    added to the aggregate value (determined as of the respective date or dates
    of grant) of the Common Stock or other securities for which this option or
    any other Incentive Options granted to Optionee prior to the Grant Date
    (whether under the Plan or any other option plan of the Corporation or any
    Parent or Subsidiary) first become exercisable during the same calendar
    year, exceed One Hundred Thousand Dollars ($100,000) in the aggregate. 
    Should such One Hundred Thousand Dollar ($100,000) limitation be exceeded
    in any calendar year, this option shall nevertheless become exercisable for
    the excess shares in such calendar year as a Non-Statutory Option.

              -    Should the exercisability of this option be accelerated upon
    a Corporate Transaction, then this option shall qualify for favorable tax
    treatment as an Incentive Option only to the extent the aggregate Fair
    Market Value (determined at the Grant Date) of the Common Stock for which
    this option first becomes exercisable in the calendar year in which the
    Corporate Transaction occurs does not, when added to the aggregate value
    (determined as of the respective date or dates of grant) of the Common
    Stock or other securities for which this option or one or more other
    Incentive Options granted to Optionee prior to the Grant Date (whether
    under the Plan or any other option plan of the Corporation or any Parent or
    Subsidiary) first become exercisable during the same calendar year, exceed
    One Hundred Thousand Dollars ($100,000) in the aggregate.  Should the
    applicable One Hundred Thousand Dollar ($100,000) limitation be exceeded in
    the calendar year of such Corporate Transaction, the option may
    nevertheless be exercised for the excess shares in such calendar year as a
    Non-Statutory Option.

              -    Should Optionee hold, in addition to this option, one or
    more other options to purchase Common Stock which become exercisable for
    the first time in the same calendar year as this option, then the foregoing
    limitations on the exercisability of such options as Incentive Options
    shall be applied on the basis of the order in which such options are
    granted.

         18.  LEAVE OF ABSENCE.  The following provisions shall apply upon the
Optionee's commencement of an authorized leave of absence:


                                          7.

<PAGE>

              (a)  The exercise schedule in effect under the Grant Notice shall
    be frozen as of the first day of the authorized leave, and this option
    shall not become exercisable for any additional installments of the Option
    Shares during the period Optionee remains on such leave.

              (b)  Should Optionee resume active Employee status within sixty
    (60) days after the start date of the authorized leave, Optionee shall, for
    purposes of the exercise schedule set forth in the Grant Notice, receive
    Service credit for the entire period of such leave.  If Optionee does not
    resume active Employee status within such sixty (60)-day period, then no
    Service credit shall be given for the period of such leave.

              (c)  If the option is designated as an Incentive Option in the
    Grant Notice, then the following additional provision shall apply:

                   -    If the leave of absence continues for more than ninety
         (90) days, then this option shall automatically convert to a
         Non-Statutory Option under the Federal tax laws on the ninety-first
         (91st) day of such leave, unless the Optionee's reemployment rights
         are guaranteed by statute or by written agreement.  Following any such
         conversion of the option, all subsequent exercises of such option,
         whether effected before or after Optionee's return to active Employee
         status, shall result in an immediate taxable event, and the
         Corporation shall be required to collect from Optionee the Federal,
         state and local income and employment withholding taxes applicable to
         such exercise.

              (d)  In no event shall this option become exercisable for any
    additional Option Shares or otherwise remain outstanding if Optionee does
    not resume Employee status prior to the Expiration Date of the option term.

                                       ADDENDUM
                                          TO
                                STOCK OPTION AGREEMENT


         The following provisions are hereby incorporated into, and are hereby
made a part of, that certain Stock Option Agreement (the "Option Agreement") by
and between Advanced Fibre Communications, Inc. (the "Corporation") and
__________________ ("Optionee") evidencing the stock option (the "Option")
granted on __________________, 199_ to Optionee under the terms of the
Corporation's 1996 Stock Incentive Plan, and such provisions shall be effective
immediately.  All capitalized terms in this Addendum, to the extent not
otherwise defined herein, shall have the meanings assigned to them in the Option
Agreement.

                           LIMITED STOCK APPRECIATION RIGHT

         1.   Optionee is hereby granted a limited stock appreciation right
exercisable upon the following terms and conditions:

              -    Optionee shall have the unconditional right (exercisable at
any time during the thirty (30)-day period immediately following a Hostile
Take-Over) to surrender the Option to the Corporation, to the extent the Option
is at the time exercisable for vested shares of Common Stock.  In return for the
surrendered Option, Optionee shall receive a cash distribution from the
Corporation in an amount equal to the excess of (A) the Take-Over Price of the
shares of Common Stock which are at the time vested under the surrendered Option
(or surrendered portion) over (B) the aggregate Exercise Price payable for such
shares.

         -    To exercise this limited stock appreciation right, Optionee must,
during the applicable thirty (30)-day exercise period, provide the Corporation
with written notice of the option surrender in which there is specified the
number of Option Shares as to which the Option is being surrendered.  Such
notice must be accompanied by the return of Optionee's copy of the Option
Agreement, together with any written amendments to such Agreement.  The cash
distribution shall be paid to Optionee within five (5) days following such
delivery date.  The exercise of the limited stock appreciation right in
accordance with the terms of this Addendum is hereby approved by the Plan
Administrator in advance of such exercise.  No further approval of the Plan
Administrator shall be required at the time of the actual option surrender and
cash distribution.  Upon receipt of such cash distribution, the Option shall be
cancelled with respect to the Option Shares for which the Option has been
surrendered, and Optionee shall cease to have any further right to acquire those
Option Shares under the Option Agreement.  The Option shall, however, remain
outstanding and exercisable for the balance of the Option Shares (if any) in
accordance with the terms of the Option Agreement, and the Corporation shall
issue a new stock option

<PAGE>

agreement (substantially in the same form of the surrendered Option Agreement)
for those remaining Option Shares.

         -    In no event may this limited stock appreciation right be
exercised when there is not a positive spread between the Fair Market Value of
the Option Shares and the aggregate Exercise Price payable for such shares.
This limited stock appreciation right shall in all events terminate upon the
expiration or sooner termination of the option term and may not be assigned or
transferred by Optionee.

         2.   For purposes of this Addendum, the following definitions shall be
in effect:

             -      A HOSTILE TAKE-OVER shall be deemed to occur in the
    event any person or related group of persons (other than the
    Corporation or a person that directly or indirectly controls, is
    controlled by, or is under common control with, the Corporation)
    directly or indirectly acquires beneficial ownership (within the
    meaning of Rule 13d-3 of the Securities Exchange Act of 1934, as
    amended) of securities possessing more than fifty percent (50%) of the
    total combined voting power of the Corporation's outstanding
    securities pursuant to a tender or exchange offer made directly to the
    Corporation's stockholders which the Board does not recommend such
    stockholders to accept.

             -     The TAKE-OVER PRICE per share shall be deemed to be
    equal to the GREATER of (A) the Fair Market Value per Option Share on
    the option surrender date or (B) the highest reported price per share
    of Common Stock paid by the tender offeror in effecting the Hostile
    Take-Over.  However, if the surrendered Option is designated as an
    Incentive Option in the Grant Notice, then the Take-Over Price shall
    not exceed the clause (A) price per share.


                                          2.

                                          TO

         The following provisions are hereby incorporated into, and are hereby
made a part of, that certain Stock Option Agreement (the "Option Agreement") by
and between Advanced Fibre Communications, Inc. (the "Corporation") and
____________________ ("Optionee") evidencing the stock option (the "Option")
granted on _____________________, 199__ to Optionee under the terms of the

otherwise defined herein, shall have the meanings assigned to them in the Option
Agreement.

                          INVOLUNTARY TERMINATION FOLLOWING
                                  CHANGE IN CONTROL

         1.   The Option shall not accelerate upon the occurrence of a Change
in Control, and the Option shall, over Optionee's continued period of Service
after the Change in Control, continue to become exercisable for the Option
Shares in accordance with the provisions of the Option Agreement.  However,
immediately upon an Involuntary Termination of Optionee's Service within
eighteen (18) months following the Change in Control, the Option, to the extent
outstanding at the time but not otherwise fully exercisable, shall automatically
accelerate so that the Option shall become immediately exercisable for all the
Option Shares at the time subject to the Option and may be exercised for any or
all of those Option Shares as fully vested shares.  The Option shall remain so
exercisable until the EARLIER of (i) the Expiration Date or (ii) the expiration
of the one (1)-year period measured from the date of the Involuntary
Termination.

         2.   For purposes of this Addendum, a CHANGE IN CONTROL shall be
deemed to occur in the event of a change in ownership or control of the
Corporation effected through either of the following transactions:

            (i)    the acquisition, directly or indirectly, by any person or
    related group of persons (other than the Corporation or a person that
    directly or indirectly controls, is controlled by, or is under common
    control with, the Corporation) of beneficial ownership (within the meaning
    of Rule 13d-3 of the Securities Exchange Act of 1934, as amended) of
    securities possessing more than fifty percent (50%) of the total combined
    voting power of the Corporation's outstanding securities pursuant to a
    tender or exchange offer made directly to the Corporation's stockholders
    which the Board does not recommend such stockholders to accept, or

           (ii)    a change in the composition of the Board over a period of
    thirty-six (36) consecutive months or less such that a majority of the
    Board members ceases, by reason of one or more contested elections for
    Board membership, to be

<PAGE>

    comprised of individuals who either (A) have been Board members
    continuously since the beginning of such period or (B) have been elected or
    nominated for election as Board members during such period by at least a
    majority of the Board members described in clause (A) who were still in
    office at the time such election or nomination was approved by the Board.

         3.   For purposes of this Addendum, an INVOLUNTARY TERMINATION shall
mean the termination of Optionee's Service by reason of:

            (i)    Optionee's involuntary dismissal or discharge by the
    Corporation for reasons other than Misconduct, or

           (ii)    Optionee's voluntary resignation following (A) a change in
    Optionee's position with the Corporation (or Parent or Subsidiary employing
    Optionee) which materially reduces Optionee's level of responsibility, (B)
    a reduction in Optionee's level of compensation (including base salary,
    fringe benefits and participation in any corporate-performance based bonus
    or incentive programs) by more than fifteen percent (15%) or (C) a
    relocation of Optionee's place of employment by more than fifty (50) miles,
    provided and only if such change, reduction or relocation is effected by
    the Corporation without Optionee's consent.

         4.   The provisions of Paragraph 1 of this Addendum shall govern the
period for which the Option is to remain exercisable following the Involuntary
Termination of Optionee's Service within eighteen (18) months after the Change
in Control and shall supersede any provisions to the contrary in Paragraph 5 of
the Option Agreement.

                                CORPORATE TRANSACTION

         1.   To the extent the Option is, in connection with a Corporate
Transaction, to be assumed or replaced with a comparable option in accordance
with Paragraph 6 of the Option Agreement, the Option shall not accelerate upon
the occurrence of that Corporate Transaction, and the Option shall accordingly
continue, over Optionee's period of Service after the Corporate Transaction, to
become exercisable for the Option Shares in one or more installments in
accordance with the provisions of the Option Agreement.  However, immediately
upon an Involuntary Termination of Optionee's Service within eighteen (18)
months following such Corporate Transaction, the Option (or any replacement
grant), to the extent outstanding at the time but not otherwise fully
exercisable, shall automatically accelerate so that the Option shall become

Option and may be exercised for any or all of those Option Shares as fully
vested shares.  The Option shall remain so exercisable until the EARLIER of (i)
the Expiration Date or (ii) the expiration of the one (1)-year period measured

    in Optionee's position with the Corporation (or Parent or Subsidiary
    employing Optionee) which materially reduces Optionee's level of

    (including base salary, fringe benefits and participation in any
    corporate-performance

<PAGE>

    based bonus or incentive programs) by more than fifteen percent (15%) or
    (C) a relocation of Optionee's place of employment by more than fifty (50)
    miles, provided and only if such change, reduction or relocation is
    effected by the Corporation without Optionee's consent.

         3.   The provisions of Paragraph 1 of this Addendum shall govern the
period for which the Option is to remain exercisable following the Involuntary
Termination of Optionee's Service within eighteen (18) months after the
Corporate Transaction and shall supersede any provisions to the contrary in
Paragraph 5 of the Option Agreement.

                         ADVANCED FIBRE COMMUNICATIONS, INC.
                           AUTOMATIC STOCK OPTION AGREEMENT



RECITALS

    A.   The Corporation has implemented an automatic option grant program 
under the Corporation's 1996 Stock Incentive Plan pursuant to which eligible 
non-employee members of the Corporation's Board will automatically receive 
special option grants at designated intervals over their period of Board 
service in order to provide such individuals with a meaningful incentive to 
continue to serve as a member of the Board. 

    B.   Optionee is an eligible non-employee Board member, and this Agreement
is executed pursuant to, and is intended to carry out the purposes of, the Plan
in connection with the automatic grant of a stock option to purchase shares of
the Corporation's Common Stock under the Plan.

    C.   The granted option is intended to be a non-statutory option which does
NOT meet the requirements of Section 422 of the Internal Revenue Code.

    D.   All capitalized terms in this Agreement, to the extent not otherwise
defined in the Agreement, shall have the meaning assigned to them in the
attached Appendix.

         NOW, THEREFORE, it is hereby agreed as follows:

         1.   GRANT OF OPTION.  The Corporation hereby grants to Optionee, as
of the Grant Date, a Non-Statutory Option to purchase up to the number of Option
Shares specified in the Grant Notice.  The Option Shares shall be purchasable
from time to time during the option term specified in Paragraph 2 at the
Exercise Price.

         2.   OPTION TERM.  This option shall have a maximum term of ten (10)
years measured from the Grant Date and shall accordingly expire at the close of
business on the Expiration Date, unless sooner terminated in accordance with
Paragraph 5, 6 or 7.

         3.   LIMITED TRANSFERABILITY.  This option may, in connection with the
Optionee's estate plan, be assigned in whole or in part during Optionee's
lifetime to one or more members of the Optionee's immediate family or to a trust
established for the exclusive benefit of one or more such family members. The
assigned portion shall be exercisable only by the person or persons who acquire
a proprietary interest in the option pursuant to such assignment. The terms
applicable to the assigned portion shall be the same as those in effect for this
option immediately prior to such assignment and shall be set forth in such
documents issued to the assignee as the Corporation may deem appropriate. Should
the

<PAGE>

Optionee die while holding this option, then this option shall be
transferred in accordance with Optionee's will or the laws of descent and
distribution. 

         4.   EXERCISABILITY/VESTING.

              (a)  This option shall be immediately exercisable for any or all
of the Option Shares, whether or not the Option Shares are vested in accordance
with the Vesting Schedule set forth in the Grant Notice, and shall remain so
exercisable until the Expiration Date or the sooner termination of the option
term under Paragraph 5, 6 or 7.

              (b)  Optionee shall, in accordance with the Vesting Schedule set
forth in the Grant Notice, vest in the Option Shares in a series of installments
over his or her period of Board service.  Vesting in the Option Shares may be
accelerated pursuant to the provisions of Paragraph 5, 6 or 7.  In no event,
however, shall any additional Option Shares vest following Optionee's cessation
of service as a Board member.

         5.   CESSATION OF BOARD SERVICE.  Should Optionee's service as a Board
member cease while this option remains outstanding, then the option term
specified in Paragraph 2 shall terminate (and this option shall cease to be
outstanding) prior to the Expiration Date in accordance with the following
provisions: 

                (i)     Should Optionee cease to serve as a Board member for
    any reason (other than death or Permanent Disability) while holding this
    option, then the period for exercising this option shall be reduced to a
    twelve (12)-month period commencing with the date of such cessation of
    Board service, but in no event shall this option be exercisable at any time
    after the Expiration Date.  During such limited period of exercisability,
    this option may not be exercised in the aggregate for more than the number
    of Option Shares (if any) in which Optionee is vested on the date of his or
    her cessation of Board service.  Upon the EARLIER of (i) the expiration of
    such twelve (12)-month period or (ii) the specified Expiration Date, the
    option shall terminate and cease to be exercisable with respect to any
    vested Option Shares for which the option has not been exercised.     

               (ii)     Should Optionee die during the twelve (12)-month period
    following his or her cessation of Board service, then the personal
    representative of Optionee's estate or the person or persons to whom the
    option is transferred pursuant to Optionee's will or in accordance with the
    laws of descent and distribution shall have the right to exercise this
    option for any or all of the Option Shares in which Optionee is vested at
    the time of Optionee's cessation of Board service (less any Option Shares
    purchased by Optionee after such cessation of Board service but prior to
    death).  Such right of exercise shall terminate, and this option shall
    accordingly cease to be exercisable for such vested Option Shares, upon the
    EARLIER of (i) the expiration of the twelve (12)-month period measured from
    the date of

                                       2.
<PAGE>

    Optionee's cessation of Board service or (ii) the specified
    Expiration Date of the option term. 

              (iii)     Should Optionee cease service as a Board member by
    reason of death or Permanent Disability, then all Option Shares at the time
    subject to this option but not otherwise vested shall immediately vest in
    full so that Optionee (or the personal representative of Optionee's estate
    or the person or persons to whom the option is transferred upon Optionee's
    death) shall have the right to exercise this option for any or all of the
    Option Shares as fully-vested shares of Common Stock at any time prior to
    the EARLIER of (i) the expiration of the twelve (12)-month period measured
    from the date of Optionee's cessation of Board service or (ii) the
    specified Expiration Date. 

               (iv)     Upon Optionee's cessation of Board service for any
    reason other than death or Permanent Disability, this option shall
    immediately terminate and cease to be outstanding with respect to any and
    all Option Shares in which Optionee is not otherwise at that time vested in
    accordance with the normal Vesting Schedule set forth in the Grant Notice
    or the special vesting acceleration provisions of Paragraph 6 or 7 below.

         6.   CORPORATE TRANSACTION.

              (a)  In the event of a Corporate Transaction, all Option Shares
at the time subject to this option but not otherwise vested shall automatically
vest so that this option shall, immediately prior to the specified effective
date for the Corporate Transaction, become fully exercisable for all of the
Option Shares at the time subject to this option and may be exercised for all or
any portion of such shares as fully-vested shares of Common Stock.  Immediately
following the consummation of the Corporate Transaction, this option shall
terminate and cease to be outstanding except to the extent assumed by the
successor corporation or its parent company.

              (b)  If this option is assumed in connection with a Corporate
Transaction, then this option shall be appropriately adjusted, immediately after
such Corporate Transaction, to apply to the number and class of securities which
would have been issuable to Optionee in consummation of such Corporate
Transaction had the option been exercised immediately prior to such Corporate
Transaction, and appropriate adjustments shall also be made to the Exercise
Price, PROVIDED the aggregate Exercise Price shall remain the same.

         7.   CHANGE IN CONTROL/HOSTILE TAKE-OVER.

              (a)  All Option Shares subject to this option at the time of a
Change in Control but not otherwise vested shall automatically vest so that this
option shall, immediately prior to the effective date of such Change in Control,
become fully exercisable

                                       3.
<PAGE>

for all of the Option Shares at the time subject to this option and may be 
exercised for all or any portion of such shares as fully-vested shares of 
Common Stock.  This option shall remain exercisable for such fully-vested 
Option Shares until the EARLIEST to occur of (i) the specified Expiration 
Date, (ii) the sooner termination of this option in accordance with Paragraph 
5 or 6 or (iii) the surrender of this option under Paragraph 7(b). 

              (b)  Optionee shall have an unconditional right (exercisable
during the thirty (30)-day period immediately following the consummation of a
Hostile Take-Over) to surrender this option to the Corporation in exchange for a
cash distribution from the Corporation in an amount equal to the excess of (i)
the Take-Over Price of the Option Shares at the time subject to the surrendered
option (whether or not those Option Shares are otherwise at the time vested)
over (ii) the aggregate Exercise Price payable for such shares.  This Paragraph
7(b) limited stock appreciation right shall in all events terminate upon the
expiration or sooner termination of the option term and may not be assigned or
transferred by Optionee.

              (c)  To exercise the Paragraph 7(b) limited stock appreciation
right, Optionee must, during the applicable thirty (30)-day exercise period,
provide the Corporation with written notice of the option surrender in which
there is specified the number of Option Shares as to which the option is being
surrendered.  Such notice must be accompanied by the return of Optionee's copy
of this Agreement, together with any written amendments to such Agreement.  The
cash distribution shall be paid to Optionee within five (5) days following such
delivery date, and neither the approval of the Plan Administrator nor the
consent of the Board shall be required in connection with such option surrender
and cash distribution.  Upon receipt of such cash distribution, this option
shall be cancelled with respect to the shares subject to the surrendered option
(or the surrendered portion), and Optionee shall cease to have any further right
to acquire those Option Shares under this Agreement.  The option shall, however,
remain outstanding for the balance of the Option Shares (if any) in accordance
with the terms and provisions of this Agreement, and the Corporation shall
accordingly issue a new stock option agreement (substantially in the same form
as this Agreement) for those remaining Option Shares. 

         8.   ADJUSTMENT IN OPTION SHARES.  Should any change be made to the
Common Stock by reason of any stock split, stock dividend, recapitalization,
combination of shares, exchange of shares or other change affecting the
outstanding Common Stock as a class without the Corporation's receipt of
consideration, appropriate adjustments shall be made to (i) the total number
and/or class of securities subject to this option and (ii) the Exercise Price in
order to reflect such change and thereby preclude a dilution or enlargement of
benefits hereunder; provided, however, that the aggregate Exercise Price shall
remain the same.

         9.   STOCKHOLDER RIGHTS.  The holder of this option shall not have any
stockholder rights with respect to the Option Shares until such person shall
have exercised the option, paid the Exercise Price and become a holder of record
of the purchased shares.

                                       4.
<PAGE>

         10.  MANNER OF EXERCISING OPTION.

              (a)  In order to exercise this option for all or any part of the
Option Shares for which the option is at the time exercisable, Optionee or, in
the case of exercise after Optionee's death, Optionee's executor, administrator,
heir or legatee, as the case may be, must take the following actions:

                     (i)     To the extent the option is exercised for
    vested Option Shares, the Secretary of the Corporation shall be
    provided with written notice of the option exercise (the "Exercise
    Notice") in substantially the form of Exhibit I attached hereto, in
    which there is specified the number of vested Option Shares to be
    purchased under the exercised option.  To the extent that the option
    is exercised for one or more unvested Option Shares, Optionee (or
    other person exercising the option) shall deliver to the Secretary of
    the Corporation a Purchase Agreement for those unvested Option Shares.

                    (ii)     The Exercise Price for the purchased shares
    shall be paid in one or more of the following alternative forms:

                        -    cash or check made payable to the
         Corporation's order; or

                        -    shares of Common Stock held by Optionee (or
         any other person or persons exercising the option) for the
         requisite period necessary to avoid a charge to the Corporation's
         earnings for financial reporting purposes and valued at Fair
         Market Value on the Exercise Date; or 

                        -    to the extent the option is exercised for
         vested Option Shares, through a special sale and remittance
         procedure pursuant to which Optionee shall provide irrevocable
         written instructions (A) to a Corporation-designated brokerage
         firm to effect the immediate sale of the vested shares purchased
         under the option and remit to the Corporation, out of the sale
         proceeds available on the settlement date, sufficient funds to
         cover the aggregate Exercise Price payable for those shares plus
         the applicable Federal, state and local income taxes required to
         be withheld by the Corporation by reason of such exercise and (B)
         to the Corporation to deliver the certificates for the purchased
         shares directly to such brokerage firm in order to complete the
         sale. 

                                       5.
<PAGE>

                   (iii)     Appropriate documentation evidencing the
    right to exercise this option shall be furnished the Corporation if
    the person or persons exercising the option is other than Optionee.

                    (iv)     Appropriate arrangement must be made with the
    Corporation for the satisfaction of all Federal, state and local
    income tax withholding requirements applicable to the option exercise.

              (b)  Except to the extent the sale and remittance procedure
specified above is utilized in connection with the exercise of the option for
vested Option Shares, payment of the Exercise Price for the purchased shares
must accompany the Exercise Notice or Purchase Agreement delivered to the
Corporation in connection with the option exercise.

              (c)  As soon as practical after the Exercise Date, the
Corporation shall issue to or on behalf of Optionee (or any other person or
persons exercising this option) a certificate or certificates representing the
purchased Option Shares.  To the extent any such Option Shares are unvested, the
certificates for those Option Shares shall be endorsed with an appropriate
legend evidencing the Corporation's repurchase rights and may be held in escrow
with the Corporation until such shares vest.

              (d)  In no event may this option be exercised for fractional
shares.

         11.  NO IMPAIRMENT OF RIGHTS.  This Agreement shall not in any way
affect the right of the Corporation to adjust, reclassify, reorganize or
otherwise make changes in its capital or business structure or to merge,
consolidate, dissolve, liquidate or sell or transfer all or any part of its
business or assets.  Nor shall this Agreement in any way be construed or
interpreted so as to affect adversely or otherwise impair the right of the
Corporation or the stockholders to remove Optionee from the Board at any time in
accordance with the provisions of applicable law.

         12.  COMPLIANCE WITH LAWS AND REGULATIONS.  

              (a)  The exercise of this option and the issuance of the Option
Shares upon such exercise shall be subject to compliance by the Corporation and
Optionee with all applicable requirements of law relating thereto and with all
applicable regulations of any stock exchange (or the Nasdaq National Market, if
applicable) on which the Common Stock may be listed for trading at the time of
such exercise and issuance.

              (b)  The inability of the Corporation to obtain approval from 
any regulatory body having authority deemed by the Corporation to be 
necessary to the lawful issuance and sale of any Common Stock pursuant to 
this option shall relieve the Corporation of any liability with respect to 
the non-issuance or sale of the Common Stock as to which such approval shall 
not have been obtained. However, the Corporation shall use its best efforts 
to obtain all such applicable approvals.

                                       6.
<PAGE>

         13.  SUCCESSORS AND ASSIGNS.  Except to the extent otherwise provided
in Paragraph 3 or 6, the provisions of this Agreement shall inure to the benefit
of, and be binding upon, the Corporation and its successors and assigns and
Optionee, Optionee's assigns and the legal representatives, heirs and legatees
of Optionee's estate.

         14.  CONSTRUCTION/GOVERNING LAW.  This Agreement and the option
evidenced hereby are made and granted pursuant to the automatic option grant
program in effect under the Plan and are in all respects limited by and subject
to the express terms and provisions of that program.  The interpretation,
performance, and enforcement of this Agreement shall be governed by the laws of
the State of Delaware without resort to that State's conflict-of-laws rules.

         15.  NOTICES.  Any notice required to be given or delivered to the
Corporation under the terms of this Agreement shall be in writing and addressed
to the Corporation at its principal corporate offices.  Any notice required to
be given or delivered to Optionee shall be in writing and addressed to Optionee
at the address indicated below Optionee's signature line on the Grant Notice. 
All notices shall be deemed effective upon personal delivery or upon deposit in
the U.S. mail, postage prepaid and properly addressed to the party to be
notified.

                               STOCK ISSUANCE AGREEMENT



         AGREEMENT made as of this _____ day of ________________ 19___, by
and between Advanced Fibre Communications, Inc., a Delaware corporation, and
________________________________, a Participant in the Corporation's 1996 Stock
Incentive Plan.

         All capitalized terms in this Agreement shall have the meaning
assigned to them in this Agreement or in the attached Appendix.

    A.   PURCHASE OF SHARES

         1.   PURCHASE.  Participant hereby purchases _________ shares of
Common Stock (the "Purchased Shares") pursuant to the provisions of the Stock
Issuance Program at the purchase price of $______ per share (the "Purchase
Price").

         2.   PAYMENT.  Concurrently with the delivery of this Agreement to the
Corporation,  Participant shall pay the Purchase Price for the Purchased Shares
in cash or check payable to the Corporation and shall deliver a duly-executed
blank Assignment Separate from Certificate (in the form attached hereto as
Exhibit I) with respect to the Purchased Shares.

         3.   STOCKHOLDER RIGHTS.  Until such time as the Corporation exercises
the Repurchase Right, Participant (or any successor in interest) shall have all
the rights of a stockholder (including voting, dividend and liquidation rights)
with respect to the Purchased Shares, subject, however, to the transfer
restrictions of this Agreement.

         4.   ESCROW.  The Corporation shall have the right to hold the
Purchased Shares in escrow until those shares have vested in accordance with the
Vesting Schedule.

         5.   COMPLIANCE WITH LAW.  Under no circumstances shall shares of
Common Stock or other assets be issued or delivered to Participant pursuant to
the provisions of this Agreement unless, in the opinion of counsel for the
Corporation or its successors, there shall have been compliance with all
applicable requirements of Federal and state securities laws, all applicable
listing requirements of any stock exchange (or the Nasdaq National Market, if
applicable) on which the Common Stock is at the time listed for trading and all
other requirements of law or of any regulatory bodies having jurisdiction over
such issuance and delivery.

<PAGE>

    B.   TRANSFER RESTRICTIONS

         1.   RESTRICTION ON TRANSFER.  Except for any Permitted Transfer,
Participant shall not transfer, assign, encumber or otherwise dispose of any of
the Purchased Shares which are subject to the Repurchase Right. 

         2.   RESTRICTIVE LEGEND.  The stock certificate for the Purchased
Shares shall be endorsed with the following restrictive legend:

              "The shares represented by this certificate are unvested and
    subject to certain repurchase rights granted to the Corporation and
    accordingly may not be sold, assigned, transferred, encumbered, or in any
    manner disposed of except in conformity with the terms of a written
    agreement dated _______________, 199__ between the Corporation and the
    registered holder of the shares (or the predecessor in interest to the
    shares).  A copy of such agreement is maintained at the Corporation's
    principal corporate offices."

         3.   TRANSFEREE OBLIGATIONS.  Each person (other than the Corporation)
to whom the Purchased Shares are transferred by means of a Permitted Transfer
must, as a condition precedent to the validity of such transfer, acknowledge in
writing to the Corporation that such person is bound by the provisions of this
Agreement and that the transferred shares are subject to the Repurchase Right to
the same extent such shares would be so subject if retained by Participant.

    C.   REPURCHASE RIGHT

         1.   GRANT.  The Corporation is hereby granted the right (the
"Repurchase Right"), exercisable at any time during the ninety (90)-day period
following the date Participant ceases for any reason to remain in Service, to
repurchase at the Purchase Price all or any portion of the Purchased Shares in
which Participant is not, at the time of his or her cessation of Service, vested
in accordance with the Vesting Schedule (such shares to be hereinafter referred
to as the "Unvested Shares").

         2.   EXERCISE OF THE REPURCHASE RIGHT.  The Repurchase Right shall be
exercisable by written notice delivered to each Owner of the Unvested Shares
prior to the expiration of the ninety (90)-day exercise period.  The notice
shall indicate the number of Unvested Shares to be repurchased and the date on
which the repurchase is to be effected, such date to be not more than thirty
(30) days after the date of such notice.  The certificates representing the
Unvested Shares to be repurchased shall be delivered to the Corporation prior to
the close of business on the date specified for the repurchase.  Concurrently
with the receipt of such stock certificates, the Corporation shall pay to Owner,
in cash or cash

                                       2.
<PAGE>

equivalent (including the cancellation of any purchase-money indebtedness), 
an amount equal to the Purchase Price previously paid for the Unvested Shares 
to be repurchased from Owner.

         3.   TERMINATION OF THE REPURCHASE RIGHT.  The Repurchase Right shall
terminate with respect to any Unvested Shares for which it is not timely
exercised under Paragraph C.2.  In addition, the Repurchase Right shall
terminate and cease to be exercisable with respect to any and all Purchased
Shares in which Participant vests in accordance with the following Vesting
Schedule:

            (i)    Upon Participant's completion of one (1) year of
    Service measured from ______________, 199__, Participant shall acquire
    a vested interest in, and the Repurchase Right shall lapse with
    respect to, twenty-five percent (25%) of the Purchased Shares.

           (ii)    Participant shall acquire a vested interest in, and the
    Repurchase Right shall lapse with respect to, the remaining Purchased
    Shares in a series of thirty six (36) successive equal monthly
    installments upon Participant's completion of each additional month of
    Service over the thirty-six (36)-month period measured from the
    initial vesting date under subparagraph (i) above.

         4.   RECAPITALIZATION.  Any new, substituted or additional securities
or other property (including cash paid other than as a regular cash dividend)
which is by reason of any Recapitalization distributed with respect to the
Purchased Shares shall be immediately subject to the Repurchase Right, but only
to the extent the Purchased Shares are at the time covered by such right. 
Appropriate adjustments to reflect such distribution shall be made to the number
and/or class of securities subject to this Agreement and to the price per share
to be paid upon the exercise of the Repurchase Right in order to reflect the
effect of any such Recapitalization upon the Corporation's capital structure;
PROVIDED, however, that the aggregate purchase price shall remain the same.

         5.   CORPORATE TRANSACTION.

              (a)  Immediately prior to the consummation of any Corporate
Transaction, the Repurchase Right shall automatically lapse in its entirety and
the Purchased Shares shall vest in full, except to the extent the Repurchase
Right is to be assigned to the successor corporation (or parent thereof) in
connection with the Corporate Transaction.

              (b)  To the extent the Repurchase Right remains in effect
following a Corporate Transaction, such right shall apply to the new capital
stock or other property (including any cash payments) received in exchange for
the Purchased Shares in consummation of the Corporate Transaction, but only to
the extent the Purchased Shares

                                       3.

<PAGE>

are at the time covered by such right. Appropriate adjustments shall be made 
to the price per share payable upon exercise of the Repurchase Right to 
reflect the effect of the Corporate Transaction upon the Corporation's 
capital structure; PROVIDED, however, that the aggregate purchase price shall 
remain the same.  The new securities or other property (including cash 
payments) issued or distributed with respect to the Purchased Shares in 
consummation of the Corporate Transaction shall immediately be deposited in 
escrow with the Corporation (or the successor entity) and shall not be 
released from escrow until Participant vests in such securities or other 
property in accordance with the same Vesting Schedule in effect for the 
Purchased Shares.

              (c)  The Repurchase Right may also be subject to termination in
whole or in part on an accelerated basis, and the Purchased Shares subject to
immediate vesting, in accordance with the terms of any special Addendum attached
to this Agreement.

    D.   SPECIAL TAX ELECTION

         1.   SECTION 83(b) ELECTION .  Under Code Section 83, the excess of
the fair market value of the Purchased Shares on the date any forfeiture
restrictions applicable to such shares lapse over the Purchase Price paid for
such shares will be reportable as ordinary income on the lapse date.  For this
purpose, the term "forfeiture restrictions" includes the right of the
Corporation to repurchase the Purchased Shares pursuant to the Repurchase Right.
Participant may elect under Code Section 83(b) to be taxed at the time the
Purchased Shares are acquired, rather than when and as such Purchased Shares
cease to be subject to such forfeiture restrictions.  Such election must be
filed with the Internal Revenue Service within thirty (30) days after the date
of this Agreement.  Even if the fair market value of the Purchased Shares on the
date of this Agreement equals the Purchase Price paid (and thus no tax is
payable), the election must be made to avoid adverse tax consequences in the
future.  THE FORM FOR MAKING THIS ELECTION IS ATTACHED AS EXHIBIT II HERETO. 
PARTICIPANT UNDERSTANDS THAT FAILURE TO MAKE THIS FILING WITHIN THE APPLICABLE
THIRTY (30)-DAY PERIOD WILL RESULT IN THE RECOGNITION OF ORDINARY INCOME AS THE
FORFEITURE RESTRICTIONS LAPSE.

         2.   FILING RESPONSIBILITY.  PARTICIPANT ACKNOWLEDGES THAT IT IS
PARTICIPANT'S SOLE RESPONSIBILITY, AND NOT THE CORPORATION'S, TO FILE A TIMELY
ELECTION UNDER CODE SECTION 83(b), EVEN IF PARTICIPANT REQUESTS THE CORPORATION
OR ITS REPRESENTATIVES TO MAKE THIS FILING ON HIS OR HER BEHALF.


    E.   GENERAL PROVISIONS

                                       4.

<PAGE>

         1.   ASSIGNMENT.  The Corporation may assign the Repurchase Right to
any person or entity selected by the Board, including (without limitation) one
or more stockholders of the Corporation.

         2.   NO EMPLOYMENT OR SERVICE CONTRACT.  Nothing in this Agreement or
in the Plan shall confer upon Participant any right to continue in Service for
any period of specific duration or interfere with or otherwise restrict in any
way the rights of the Corporation (or any Parent or Subsidiary employing or
retaining Participant) or of Participant, which rights are hereby expressly
reserved by each, to terminate Participant's Service at any time for any reason,
with or without cause.

         3.   NOTICES.  Any notice required to be given under this Agreement
shall be in writing and shall be deemed effective upon personal delivery or upon

addressed to the party entitled to such notice at the address indicated below
such party's signature line on this Agreement or at such other address as such
party may designate by ten (10) days advance written notice under this paragraph
to all other parties to this Agreement.

         4.   NO WAIVER.  The failure of the Corporation in any instance to
exercise the Repurchase Right shall not constitute a waiver of any other
repurchase rights that may subsequently arise under the provisions of this
Agreement or any other agreement between the Corporation and Participant.  No
waiver of any breach or condition of this Agreement shall be deemed to be a
waiver of any other or subsequent breach or condition, whether of like or
different nature.

         5.   CANCELLATION OF SHARES.  If the Corporation shall make available,
at the time and place and in the amount and form provided in this Agreement, the
consideration for the Purchased Shares to be repurchased in accordance with the
provisions of this Agreement, then from and after such time, the person from
whom such shares are to be repurchased shall no longer have any rights as a
holder of such shares (other than the right to receive payment of such
consideration in accordance with this Agreement).  Such shares shall be deemed
purchased in accordance with the applicable provisions hereof, and the
Corporation shall be deemed the owner and holder of such shares, whether or not
the certificates therefor have been delivered as required by this Agreement.

         6.   PARTICIPANT UNDERTAKING.  Participant hereby agrees to take
whatever additional action and execute whatever additional documents the
Corporation may deem necessary or advisable in order to carry out or effect one
or more of the obligations or restrictions imposed on either Participant or the
Purchased Shares pursuant to the provisions of this Agreement.

         7.   AGREEMENT IS ENTIRE CONTRACT.  This Agreement constitutes the
entire contract between the parties hereto with regard to the subject matter
hereof.  This

                                       5.

<PAGE>

Agreement is made pursuant to the provisions of the Plan and shall
in all respects be construed in conformity with the terms of the Plan.

         8.   GOVERNING LAW.  This Agreement shall be governed by, and
construed in accordance with, the laws of the State of Delaware without resort
to that State's conflict-of-laws rules.

         9.   COUNTERPARTS.  This Agreement may be executed in counterparts,
each of which shall be deemed to be an original, but all of which together shall
constitute one and the same instrument.

         10.  SUCCESSORS AND ASSIGNS.  The provisions of this Agreement shall
inure to the benefit of, and be binding upon, the Corporation and its successors
and assigns and upon Participant, Participant's assigns and the legal
representatives, heirs and legatees of Participant's estate, whether or not any
such person shall have become a party to this Agreement and have agreed in
writing to join herein and be bound by the terms hereof.

         IN WITNESS WHEREOF, the parties have executed this Agreement on the
day and year first indicated above.

                         ADVANCED FIBRE COMMUNICATIONS, INC.
                             EMPLOYEE STOCK PURCHASE PLAN
                  (all share numbers have been adjusted to reflect 
                  a two-for-one stock split effected in August 1996)


    I.   PURPOSE OF THE PLAN

         This Employee Stock Purchase Plan is intended to promote the interests
of Advanced Fibre Communications, Inc. by providing eligible employees with the
opportunity to acquire a proprietary interest in the Corporation through
participation in a payroll-deduction based employee stock purchase plan designed
to qualify under Section 423 of the Code.

         Capitalized terms herein shall have the meanings assigned to such
terms in the attached Appendix.

 II.     ADMINISTRATION OF THE PLAN

         The Plan Administrator shall have full authority to interpret and
construe any provision of the Plan and to adopt such rules and regulations for
administering the Plan as it may deem necessary in order to comply with the
requirements of Code Section 423.  Decisions of the Plan Administrator shall be
final and binding on all parties having an interest in the Plan.

III.     STOCK SUBJECT TO PLAN

         A.   The stock purchasable under the Plan shall be shares of
authorized but unissued or reacquired Common Stock, including shares of Common
Stock purchased on the open market.  The maximum number of shares of Common
Stock which may be issued over the term of the Plan shall not exceed One Million
Five Hundred Thousand (1,500,000) shares.

         B.   Should any change be made to the Common Stock by reason of any
stock split, stock dividend, recapitalization, combination of shares, exchange
of shares or other change affecting the outstanding Common Stock as a class
without the Corporation's receipt of consideration, appropriate adjustments
shall be made to (i) the maximum number and class of securities issuable under
the Plan, (ii) the maximum number and class of securities purchasable per
Participant on any one Purchase Date and (iii) the number and class of
securities and the price per share in effect under each outstanding purchase
right in order to prevent the dilution or enlargement of benefits thereunder.

<PAGE>

 IV.     OFFERING PERIODS

         A.   Shares of Common Stock shall be offered for purchase under the
Plan through a series of successive offering periods until such time as (i) the
maximum number of shares of Common Stock available for issuance under the Plan
shall have been purchased or (ii) the Plan shall have been sooner terminated.

         B.   Each offering period shall be of such duration (not to exceed
twenty-four (24) months) as determined by the Plan Administrator prior to the
start date.  The initial offering period shall commence at the Effective Time
and terminate on the last business day in July 1998.  The next offering period
shall commence on the first business day in August 1998, and subsequent offering
periods shall commence as designated by the Plan Administrator.

         C.   Each offering period shall be comprised of a series of one or
more successive Purchase Intervals.  Purchase Intervals shall run from the first
business day in February each year to the last business day in July of the same
year and from the first business day in August each year to the last business
day in January of the following year.  However, the initial Purchase Interval in
effect under the initial offering period shall commence at the Effective Time
and terminate on the last business day in January 1997.

         D.   Should the Fair Market Value per share of Common Stock on any
Purchase Date within an offering period be less than the Fair Market Value per
share of Common Stock on the start date of that offering period, then that
offering period shall automatically terminate with the purchase of shares of
Common Stock on such Purchase Date, and a new offering period shall commence on
the next business day.  The new offering period shall have a duration of twenty
four (24) months, unless a shorter duration is established by the Plan
Administrator within five (5) business days following the start date of that
offering period.

  V.     ELIGIBILITY

         A.   Each individual who is an Eligible Employee on the start date of
any offering period under the Plan may enter that offering period on such start
date or on any subsequent Semi-Annual Entry Date within that offering period,
provided he or she remains an Eligible Employee.

         B.   Each individual who first becomes an Eligible Employee after the
start date of an offering period may enter that offering period on any
subsequent Semi-Annual Entry Date within that offering period on which he or she
is an Eligible Employee.

         C.   The date an individual enters an offering period shall be
designated his or her Entry Date for purposes of that offering period.

                                       2.
<PAGE>

         D.   To participate in the Plan for a particular offering period, the
Eligible Employee must complete the enrollment forms prescribed by the Plan
Administrator (including a stock purchase agreement and a payroll deduction
authorization) and file such forms with the Plan Administrator (or its
designate) on or before his or her scheduled Entry Date.

 VI.     PAYROLL DEDUCTIONS

         A.   The payroll deduction authorized by the Participant for purposes
of acquiring shares of Common Stock during an offering period may be any
multiple of one percent (1%) of the Cash Earnings paid to the Participant during
each Purchase Interval within that offering period, up to a maximum of ten
percent (10%).  The deduction rate so authorized shall continue in effect
throughout the offering period, except to the extent such rate is changed in
accordance with the following guidelines:

                (i)     The Participant may, at any time during the
    offering period, reduce his or her rate of payroll deduction to become
    effective as soon as possible after filing the appropriate form with
    the Plan Administrator.  The Participant may not, however, effect more
    than one (1) such reduction per Purchase Interval.

               (ii)     The Participant may, prior to the commencement of
    any new Purchase Interval within the offering period, increase the
    rate of his or her payroll deduction by filing the appropriate form
    with the Plan Administrator.  The new rate (which may not exceed the
    ten percent (10%) maximum) shall become effective on the start date of
    the first Purchase Interval following the filing of such form.

         B.   Payroll deductions shall begin on the first pay day following the
Participant's Entry Date into the offering period and shall (unless sooner
terminated by the Participant) continue through the pay day ending with or
immediately prior to the last day of that offering period.  The amounts so
collected shall be credited to the Participant's book account under the Plan,
but no interest shall be paid on the balance from time to time outstanding in
such account.  The amounts collected from the Participant shall not be held in
any segregated account or trust fund and may be commingled with the general
assets of the Corporation and used for general corporate purposes.

         C.   Payroll deductions shall automatically cease upon the termination
of the Participant's purchase right in accordance with the provisions of the
Plan.

         D.   The Participant's acquisition of Common Stock under the Plan on
any Purchase Date shall neither limit nor require the Participant's acquisition
of Common Stock on any subsequent Purchase Date, whether within the same or a
different offering period.

                                       3.
<PAGE>

 VII.    PURCHASE RIGHTS

         A.   GRANT OF PURCHASE RIGHT.  A Participant shall be granted a
separate purchase right for each offering period in which he or she
participates.  The purchase right shall be granted on the Participant's Entry
Date into the offering period and shall provide the Participant with the right
to purchase shares of Common Stock, in a series of successive installments over
the remainder of such offering period, upon the terms set forth below.  The
Participant shall execute a stock purchase agreement embodying such terms and
such other provisions (not inconsistent with the Plan) as the Plan Administrator
may deem advisable.

         Under no circumstances shall purchase rights be granted under the Plan
to any Eligible Employee if such individual would, immediately after the grant,
own (within the meaning of Code Section 424(d)) or hold outstanding options or
other rights to purchase, stock possessing five percent (5%) or more of the
total combined voting power or value of all classes of stock of the Corporation
or any Corporate Affiliate.

         B.   EXERCISE OF THE PURCHASE RIGHT.  Each purchase right shall be
automatically exercised in installments on each successive Purchase Date within
the offering period, and shares of Common Stock shall accordingly be purchased
on behalf of each Participant (other than Participants whose payroll deductions
have previously been refunded pursuant to the Termination of Purchase Right
provisions below) on each such Purchase Date.  The purchase shall be effected by
applying the Participant's payroll deductions for the Purchase Interval ending
on such Purchase Date to the purchase of whole shares of Common Stock at the
purchase price in effect for the Participant for that Purchase Date.

         C.   PURCHASE PRICE.  The purchase price per share at which Common
Stock will be purchased on the Participant's behalf on each Purchase Date within
the offering period shall be equal to eighty-five percent (85%) of the LOWER of
(i) the Fair Market Value per share of Common Stock on the Participant's Entry
Date into that offering period or (ii) the Fair Market Value per share of Common
Stock on that Purchase Date.  

         D.   NUMBER OF PURCHASABLE SHARES.  The number of shares of Common
Stock purchasable by a Participant on each Purchase Date during the offering
period shall be the number of whole shares obtained by dividing the amount
collected from the Participant through payroll deductions during the Purchase
Interval ending with that Purchase Date by the purchase price in effect for the
Participant for that Purchase Date.  However, the maximum number of shares of
Common Stock purchasable per Participant on any one Purchase Date shall not
exceed One Thousand Five Hundred (1,500) shares, subject to periodic adjustments
in the event of certain changes in the Corporation's capitalization.

         E.   EXCESS PAYROLL DEDUCTIONS.  Any payroll deductions not applied to
the  purchase of shares of Common Stock on any Purchase Date because they are
not sufficient

                                       4.
<PAGE>

to purchase a whole share of Common Stock shall be held for the
purchase of Common Stock on the next Purchase Date.  However, any payroll
deductions not applied to the purchase of Common Stock by reason of the
limitation on the maximum number of shares purchasable by the Participant on the
Purchase Date shall be promptly refunded.

         F.   TERMINATION OF PURCHASE RIGHT.  The following provisions shall
govern the termination of outstanding purchase rights:

                (i)     A Participant may, at any time prior to the next
    scheduled Purchase Date in the offering period, terminate his or her
    outstanding purchase right by filing the appropriate form with the
    Plan Administrator (or its designate), and no further payroll
    deductions shall be collected from the Participant with respect to the
    terminated purchase right.  Any payroll deductions collected during
    the Purchase Interval in which such termination occurs shall, at the
    Participant's election, be immediately refunded or held for the
    purchase of shares on the next Purchase Date.  If no such election is
    made at the time such purchase right is terminated, then the payroll
    deductions collected with respect to the terminated right shall be
    refunded as soon as possible.

               (ii)     The termination of such purchase right shall be
    irrevocable, and the Participant may not subsequently rejoin the
    offering period for which the terminated purchase right was granted. 
    In order to resume participation in any subsequent offering period,
    such individual must re-enroll in the Plan (by making a timely filing
    of the prescribed enrollment forms) on or before his or her scheduled
    Entry Date into that offering period.

              (iii)     Should the Participant cease to remain an Eligible
    Employee for any reason (including death, disability or change in
    status) while his or her purchase right remains outstanding, then that
    purchase right shall immediately terminate, and all of the
    Participant's payroll deductions for the Purchase Interval in which
    the purchase right so terminates shall be immediately refunded. 
    However, should the Participant cease to remain in active service by
    reason of an approved unpaid leave of absence, then the Participant
    shall have the right, exercisable up until the last business day of
    the Purchase Interval in which such leave commences, to (a) withdraw
    all the payroll deductions collected to date on his or her behalf for
    that Purchase Interval or (b) have such funds held for the purchase of
    shares on his or her behalf on the next scheduled Purchase Date.  In
    no event, however, shall any further payroll deductions be collected
    on the Participant's behalf during such leave.  Upon the Participant's
    return to active service, his or her payroll deductions under the Plan
    shall automatically resume at the rate in effect at the time the leave
    began, unless the Participant withdraws from the Plan prior to his or
    her return.

                                       5.
<PAGE>

         G.   CORPORATE TRANSACTION.  Each outstanding purchase right shall
automatically be exercised, immediately prior to the effective date of any
Corporate Transaction, by applying the payroll deductions of each Participant
for the Purchase Interval in which such Corporate Transaction occurs to the
purchase of whole shares of Common Stock at a purchase price per share equal to
eighty-five percent (85%) of the LOWER of (i) the Fair Market Value per share of
Common Stock on the Participant's Entry Date into the offering period in which
such Corporate Transaction occurs or (ii) the Fair Market Value per share of
Common Stock immediately prior to the effective date of such Corporate
Transaction.  However, the applicable limitation on the number of shares of
Common Stock purchasable per Participant shall continue to apply to any such
purchase. 

         The Corporation shall use its best efforts to provide at least ten
(10)-days prior written notice of the occurrence of any Corporate Transaction,
and Participants shall, following the receipt of such notice, have the right to
terminate their outstanding purchase rights prior to the effective date of the
Corporate Transaction.

         H.   PRORATION OF PURCHASE RIGHTS.  Should the total number of shares
of Common Stock to be purchased pursuant to outstanding purchase rights on any
particular date exceed the number of shares then available for issuance under
the Plan, the Plan Administrator shall make a pro-rata allocation of the
available shares on a uniform and nondiscriminatory basis, and the payroll
deductions of each Participant, to the extent in excess of the aggregate
purchase price payable for the Common Stock pro-rated to such individual, shall
be refunded.

         I.   ASSIGNABILITY.  The purchase right shall be exercisable only by
the Participant and shall not be assignable or transferable by the Participant.

         J.   STOCKHOLDER RIGHTS.  A Participant shall have no stockholder
rights with respect to the shares subject to his or her outstanding purchase
right until the shares are purchased on the Participant's behalf in accordance
with the provisions of the Plan and the Participant has become a holder of
record of the purchased shares.

VIII.    ACCRUAL LIMITATIONS

         A.   No Participant shall be entitled to accrue rights to acquire
Common Stock pursuant to any purchase right outstanding under this Plan if and
to the extent such accrual, when aggregated with (i) rights to purchase Common
Stock accrued under any other purchase right granted under this Plan and (ii)
similar rights accrued under other employee stock purchase plans (within the
meaning of Code Section 423) of the Corporation or any Corporate Affiliate,
would otherwise permit such Participant to purchase more than Twenty-Five
Thousand Dollars ($25,000) worth of stock of the Corporation or any Corporate
Affiliate (determined on the basis of the Fair Market Value per share on the
date or dates such rights are granted) for each calendar year such rights are at
any time outstanding.

                                       6.
<PAGE>

         B.   For purposes of applying such accrual limitations to the purchase
rights granted under the Plan, the following provisions shall be in effect:

                (i)     The right to acquire Common Stock under each
    outstanding purchase right shall accrue in a series of installments on
    each successive Purchase Date during the offering period on which such
    right remains outstanding.

               (ii)     No right to acquire Common Stock under any
    outstanding purchase right shall accrue to the extent the Participant
    has already accrued in the same calendar year the right to acquire
    Common Stock under one (1) or more other purchase rights at a rate
    equal to Twenty-Five Thousand Dollars ($25,000) worth of Common Stock
    (determined on the basis of the Fair Market Value per share on the
    date or dates of grant) for each calendar year such rights were at any
    time outstanding.

         C.   If by reason of such accrual limitations, any purchase right of a
Participant does not accrue for a particular Purchase Interval, then the payroll
deductions which the Participant made during that Purchase Interval with respect
to such purchase right shall be promptly refunded.

         D.   In the event there is any conflict between the provisions of this
Article and one or more provisions of the Plan or any instrument issued
thereunder, the provisions of this Article shall be controlling.

  IX.    EFFECTIVE DATE AND TERM OF THE PLAN

         A.   The Plan was adopted by the Board on July 12, 1996 and shall
become effective at the Effective Time, PROVIDED no purchase rights granted
under the Plan shall be exercised, and no shares of Common Stock shall be issued
hereunder, until (i) the Plan shall have been approved by the stockholders of
the Corporation and (ii) the Corporation shall have complied with all applicable
requirements of the 1933 Act (including the registration of the shares of Common
Stock issuable under the Plan on a Form S-8 registration statement filed with
the Securities and Exchange Commission), all applicable listing requirements of
any stock exchange (or the Nasdaq National Market, if applicable) on which the
Common Stock is listed for trading and all other applicable requirements
established by law or regulation.  In the event such stockholder approval is not
obtained, or such compliance is not effected, within twelve (12) months after
the date on which the Plan is adopted by the Board, the Plan shall terminate and
have no further force or effect, and all sums collected from Participants during
the initial offering period hereunder shall be refunded.

                                       7.
<PAGE>

         B.   Unless sooner terminated by the Board, the Plan shall terminate
upon the EARLIEST of (i) the last business day in July 2006, (ii) the date on
which all shares available for issuance under the Plan shall have been sold
pursuant to purchase rights exercised under the Plan or (iii) the date on which
all purchase rights are exercised in connection with a Corporate Transaction. 
No further purchase rights shall be granted or exercised, and no further payroll
deductions shall be collected, under the Plan following such termination.

   X.    AMENDMENT OF THE PLAN

         The Board may alter, amend, suspend or discontinue the Plan at any
time to become effective immediately following the close of any Purchase
Interval.  However, the Board may not, without the approval of the Corporation's
stockholders, (i) increase the number of shares of Common Stock issuable under
the Plan or the maximum number of shares purchasable per Participant on any one
Purchase Date, except for permissible adjustments in the event of certain
changes in the Corporation's capitalization, (ii) alter the purchase price
formula so as to reduce the purchase price payable for the shares of Common
Stock purchasable under the Plan or (iii) modify the eligibility requirements
for participation in the Plan.

    XI.  GENERAL PROVISIONS

         A.   All costs and expenses incurred in the administration of the Plan
shall be paid by the Corporation; however, each Plan Participant shall bear all
costs and expenses incurred by such individual in the sale or other disposition
of any shares purchased under the Plan.

         B.   Nothing in the Plan shall confer upon the Participant any right
to continue in the employ of the Corporation or any Corporate Affiliate for any
period of specific duration or interfere with or otherwise restrict in any way
the rights of the Corporation (or any Corporate Affiliate employing such person)
or of the Participant, which rights are hereby expressly reserved by each, to
terminate such person's employment  at any time for any reason, with or without
cause.

         C.   The provisions of the Plan shall be governed by the laws of the
State of Delaware without resort to that State's conflict-of-laws rules.

<PAGE>

                                                                 EXHIBIT 99.15

                         ADVANCED FIBRE COMMUNICATIONS, INC.
                               STOCK PURCHASE AGREEMENT


    I hereby elect to participate in the Employee Stock Purchase Plan (the
"ESPP") effective with the Entry Date specified below, and I hereby subscribe to
purchase shares of Common Stock of Advanced Fibre Communications, Inc. (the
"Corporation") in accordance with the provisions of this Agreement and the ESPP.
I hereby authorize payroll deductions from each of my paychecks following my
entry into the ESPP in the 1% multiple of my earnings (not to exceed a maximum
of 10%) specified in my attached Enrollment Form.

    Each offering period is divided into a series of successive purchase
intervals.  The initial purchase interval is to begin at the time of the initial
public offering of the Common Stock and end on January 31, 1997.  Subsequent
purchase intervals will each be of six (6) months duration and will run from the
first business day of February to the last business day of July each year and
from the first business day of August each year until the last business of
January in the following year.  My participation will automatically remain in
effect from one offering period to the next in accordance with this Agreement
and my payroll deduction authorization, unless I withdraw from the ESPP or
change the rate of my payroll deduction or unless my employment status changes. 
I may reduce the rate of my payroll deductions on one occasion per purchase
interval, and I may increase my rate of payroll deduction to become effective at
the beginning of any subsequent purchase interval within the offering period.

    My payroll deductions will be converted into U.S. Dollars on the last U.S.
business day of each month.  My payroll deductions as so converted will be
accumulated for the purchase of shares of the Corporation's Common Stock on the
last U.S. business day of each purchase interval within the offering period. 
The purchase price per share will be equal to 85% of the LOWER of (i) the fair
market value per share of Common Stock on my entry date into the offering period
or (ii) the fair market value per share on the semi-annual purchase date.  I
will also be subject to ESPP restrictions (i) limiting the maximum number of
shares which I may purchase on any one purchase date to 1,500 shares and (ii)
prohibiting me from purchasing more than U.S.$25,000 worth of Common Stock for
each calendar year my purchase right remains outstanding.

    I may withdraw from the ESPP at any time prior to the last business day of
a purchase interval and elect either to have the Corporation refund all my
payroll deductions for that purchase interval or to have those payroll
deductions applied to the purchase of shares of the Corporation's Common Stock
at the end of such interval.  However, I may not rejoin that particular offering
period at any later date.  Upon the termination of my employment for any reason,
including death or disability, or my loss of eligible employee status, my
participation in the ESPP will immediately cease and all my payroll deductions
for the purchase interval in which my employment terminates or my loss of
eligibility occurs will automatically be refunded.

    If I take an unpaid leave of absence, my payroll deductions will
immediately cease, and any payroll deductions for the purchase interval in which
my leave begins will, at my election, either be refunded or applied to the
purchase of shares of Common Stock at the end of that purchase interval. Upon my
return to active service, my payroll deductions will automatically resume at the
rate in effect when my leave began. 

    A stock certificate for the shares purchased on my behalf at the end of
each purchase interval will automatically be deposited into a brokerage account
which the Corporation will open on my behalf.  I will notify the Corporation of
any sale or disposition of my ESPP shares, and I will satisfy all applicable
income and employment tax withholding requirements at the time of such sale or
disposition.

    The Corporation has the right, exercisable in its sole discretion, to amend
or terminate the ESPP at any time, with such amendment or termination to become
effective immediately following the exercise of outstanding purchase rights at
the end of any current purchase interval.  Should the Corporation elect to
terminate the ESPP, I will have no further rights to purchase shares of Common
Stock pursuant to this Agreement.

    I have received a copy of the official Plan Prospectus summarizing the
major features of the ESPP.  I have read this Agreement and the Prospectus and
hereby agree to be bound by the terms of both this Agreement and the ESPP.  The
effectiveness of this Agreement is dependent upon my eligibility to participate
in the ESPP.

    I acknowledge that I have received and may continue to receive the
opportunity to purchase stock under the ESPP.  I understand that the grant of a
purchase right in one year or at one time does not in any way obligate the
Corporation or AFTEK-HK to make a grant or award in any future year or in any
given amount.  I acknowledge and understand that the ESPP is wholly
discretionary in nature and is not to be considered part of my normal or
expected compensation subject to severance, resignation, redundancy or similar
pay.

    I hereby authorize and direct AFTEK-HK to disclose to the Corporation or
any of its subsidiaries such information regarding my employment, the nature and
