                       FASTCOMM COMMUNICATIONS CORPORATION
                             1999 STOCK OPTION PLAN

                                   ARTICLE ONE

                               GENERAL PROVISIONS

     I.     PURPOSE OF THE PLAN

     This 1999 Stock Option Plan is intended to promote the interests of
FastComm Communications Corporation, a Virginia 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.

     This Plan shall supplement the authorized share reserve under the
Corporation's 1992 Qualified and Non-Qualified Stock Option Plans (the "1992
Plans"), and share issuances under this Plan shall not reduce or otherwise
affect the number of shares of the Corporation's common stock available for
issuance under the 1992 Plans. In addition, share issuances under the 1992 Stock
Plans shall not reduce or otherwise affect the number of shares of the
Corporation's common stock available for issuance under this Plan.

     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 three separate equity programs:

        (i) 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,

        (ii) 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), and

        (iii) the Automatic Option Grant Program under which Eligible
Directors shall automatically receive option grants at periodic intervals to
purchase shares of Common Stock.



                                      II-12

   2

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

     III.   ADMINISTRATION OF THE PLAN

     A. The Primary Committee shall have sole and exclusive authority to
administer the Discretionary Option Grant and Stock Issuance Programs with
respect to all Section 16 Insiders. 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.

     B. 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.

     C. 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 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 or Stock Issuance Program under its jurisdiction or
any option or stock issuance thereunder.

     D. 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.

     E. Administration of the Automatic Option Grant Program shall be
self-executing in accordance with the terms of that program, and no Plan
Administrator shall exercise any discretionary functions with respect to option
grants made thereunder.

     IV.    ELIGIBILITY

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



                                      II-13

   3

        (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. Each Plan Administrator shall, within the scope of its administrative
jurisdiction under the Plan, have full authority (subject to the provisions of
the Plan) 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 to be paid for such shares.

     C. 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.

     D. The individuals eligible to participate in the Automatic Option Grant
Program shall be limited to (i) those individuals who are first elected or
appointed as non-employee Board members after the Effective Date, whether
through appointment by the Board or election by the Corporation's shareholders,
and (ii) those individuals who continue to serve as non-employee Board members
after one or more Annual Stockholders Meetings, beginning with the 1999 Annual
Meeting. 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 who is, directly or
indirectly, a 5% Stockholder or who is otherwise affiliated with, or a
representative of, a 5% Stockholder be eligible to receive any option grants
under the Automatic 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
reserved for issuance over the term of the Plan shall not exceed 1,500,000
shares. Such share reserve



                                      II-14

   4

shall be in addition to the shares of Common Stock reserved for issuance under
the 1992 Plans and share issuances under the 1992 Plans shall have no effect
upon the number of shares of Common Stock which remain available issuance under
this Plan.

     B. Shares of Common Stock subject to outstanding options under this 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 or such option or stock issuance.

     C. 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/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 automatic option grants are to be
subsequently made per Eligible Director under the Automatic Option Grant Program
and (iv) the number and/or class of securities and the exercise price per share
in effect under each outstanding option in order to prevent the dilution or
enlargement of benefits thereunder. 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 Five 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 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 transaction.

     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.

     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) 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 with respect to any
shares in which the Optionee is not vested on the date of such cessation of
Service.

               (iv) 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.

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



                                     II-17

   7


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

     D.     Shareholder Rights

     The holder of an option shall have no shareholder 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 records 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.
Non-Statutory Options shall be subject to the same transfer restrictions, except
that 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-18

     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 Five 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.

     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 (1) 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 Corporation 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 for
any or all of those shares as fully-vested shares of Common Stock.

     B.     All outstanding repurchase rights shall terminate automatically, and
the shares of Common Stock subject to those terminated rights shall immediately
vest in full,



                                      II-19

   9

in the event of any Corporate Transaction.

     C.     Immediately following the consummation of the Corporate Transaction,
all outstanding options shall terminate and cease to be outstanding, except to
the extent covered by Section A or B above.

     D.     The Plan Administrator shall have the discretion, exercisable either
at the time the option is granted or at any time while the option remains
outstanding, to provide for the automatic acceleration of one or more
outstanding options (and the automatic termination of one or more outstanding
repurchase rights with the immediate vesting of the shares of Common Stock
subject to those rights) upon the Involuntary Termination of the Optionee's
Service within a specified period (not to exceed eighteen (18) months) following
the effective date of a Change in Control. Any options so accelerated shall
remain fully exercisable until the expiration or sooner termination of the
option term.

     E.     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.

     F.     The grant of options under the Discretionary 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.    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 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 option 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



                                      II-20

   10

               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 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 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 rejected by the Plan
               Administrator, then the Optionee shall retain whatever rights the
               Optionee had under the surrender 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 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 such 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) The grant of such limited stock appreciation right shall
               automatically constitute the pre-approval by the Plan
               Administrator of the any subsequent exercise of that right in
               accordance with the terms of this



                                      II-21

   11

               Paragraph C. Accordingly, no further approval of the Plan
               Administrator or the Board shall be required at the time of the
               actual surrender of such option and the cash distribution to
               which the optionee shall thereupon become entitled.

         (iv)  The balance of the option (if any) shall continue in full force
               and effect in accordance with the documents evidencing such
               option.

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



                                      II-23

   13

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 Participants
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 shareholder 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 shareholder 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 such surrendered shares.

     5. The Plan Administrator may in its discretion waive the surrender and
cancellation of one or more unvested shares of Common Stock (or other assets
attributable thereto) which would otherwise occur upon the cessation of the
Participant's Service or the non-completion of the vesting schedule applicable
to such shares. Such waiver shall result in the immediate vesting of the
Participant's interest in the shares of Common Stock 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 of non- attainment of the
applicable performance objectives.

the time the unvested shares are issued or at any time while the Corporation's
repurchase right remains outstanding, to provide for the automatic termination
of one or more outstanding repurchase rights and the immediate vesting of the
shares of Common Stock subject to those rights upon the Involuntary Termination
of the Participant's Service within a specified period (not to exceed eighteen
(18) months) following the effective date of any Change in Control.

     III.   SHARE ESCROW/LEGENDS

                         AUTOMATIC OPTION GRANT PROGRAM

     I.     OPTION TERMS

     A. SUCCESSOR PROGRAM. Shareholder approval of this Plan at the 1999 Annual
Meeting shall also constitute approval of all option grants made to Eligible
Directors pursuant to the provisions of this Automatic Option Grant Program.

     B. GRANT DATES. Option grants shall be made under the Plan on the dates
specified below:

        1. Each Eligible Director who is first elected or appointed as a
non-employee Board member after the Effective Date shall automatically be
granted, on the date of such initial election or appointment, a Non-Statutory
Option to purchase 30,000 shares of Common Stock.

        2. On the date of each Annual Shareholder Meeting, beginning with the
1999 Annual Meeting, each individual who is to continue to serve as an Eligible
Director after such meeting, shall automatically be granted, whether or not such
individual is standing for re-election as a Board member at that Annual Meeting,
a Non-Statutory Option to purchase an additional 30,000 shares of Common Stock,
provided such individual has served as a non-employee Board member for at least
six (6) months prior to the date of such Annual Meeting. There shall be no limit
on the number of such 30,000 share option



                                      II-25

   15

grants any one Eligible Director may receive over his or her period of Board
service.

     C.     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.

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

     E.     EXERCISE AND VESTING OF OPTIONS. Each option shall be exercisable
for one third of the options granted annually, commencing one year after the
date of grant. 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. The
shares subject to each initial grant shall vest, in a series of three (3)
successive equal annual installments over the Optionee's period of continued
service as a Board member, with the first such installment to vest upon the
Optionee's completion of one (1) year of Board service measured from the option
grant date. The shares subject to each annual grant shall vest, and the
Corporation's repurchase right with respect to those shares shall lapse, on the
day immediately preceding the date of the next Annual Shareholders Meeting
following the grant date, provided the Optionee continues in Board service
through such day.

     F.     EFFECT OF 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



                                      II-26

   16

following such cessation of Board service, be exercised for all or any portion
of such 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, terminate and cease to be
outstanding with respect to any shares in which the Optionee is not bested on
the date of such cessation of Board service.

     II.    CORPORATE TRANSACTION/CHANGE IN CONTROL/HOSTILE TAKE-0VER

     A. In the event of any Corporate Transaction, the shares of Common Stock at
the time subject to each outstanding option under the Automatic Option Grant
Program 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 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 such
shares as fully-vested shares of Common Stock.

     B. In the event of 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 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 such shares as fully-vested shares of Common Stock.

     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 option
grant held by him or her under this Automatic Option Grant Program. 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 the 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.
Such surrender right shall form a part of each option grant made under this
Automatic Option Grant Program, and shareholder approval of this Plan shall
constitute pre-approval of this Paragraph C. Accordingly, no approval of the
Board or the Plan Administrator shall be required at the time of the actual
option surrender and the cash distribution to which the optionee shall thereupon
become entitled.

     D. 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.

                                  MISCELLANEOUS

     A. 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 for shares issued under the Stock Issuance Program by delivering
a 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. Promissory
notes may be authorized with or without security or collateral. In all events,
the maximum credit available to the Optionee or Participant may not 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.

     B. The Plan Administrator may, in its discretion, determine that one or
more such promissory notes shall be subject to forgiveness by the Corporation in
whole or in part upon such terms as the Plan Administrator may deem appropriate.

     II.    TAX WITHHOLDING

     A. The Corporation's obligation to deliver shares of Common Stock upon the
exercise of options or stock appreciation rights or upon 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 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:

        (i) Stock Withholding: The election to have the Corporation withhold,
     from the shares of Common Stock otherwise issuable upon the exercise of



                                      II-28

   18

     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.

        (ii) 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 or shares 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 became effective on the 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 shareholders. If such
shareholder approval is not obtained within twelve (12) months after the
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 was adopted by the Board on July 26, 1999 subject to

the date on which all shares available for issuance under the Plan shall have
been issued as vested shares pursuant to the exercise of options or the issuance
of shares under the Plan or (iii) the termination of all outstanding options in
connection with a Corporate Transaction. Should this Plan terminate on October
29, 2009, then all options and unvested stock issuances outstanding on such date
shall thereafter continue to have force and effect in accordance with the
provisions of the documents evidencing such options or issuances.

     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, stock appreciation rights 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
shareholder approval pursuant to applicable law or regulations.

     B. Options to purchase shares of Common Stock may be granted under the
Discretionary Option Grant Program 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 are held in escrow until there is
obtained shareholder approval of



                                      II-29

   19

an amendment sufficiently increasing the number of shares of Common Stock
available for issuance under the Plan. If such shareholder 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.

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 option or stock
appreciation right under the Plan and the issuance of any shares of Common Stock

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 options and stock appreciation rights granted under it and
the shares of Common Stock issued pursuant to it.

     B. No shares of Common Stock or 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 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
