                                 VERISIGN, INC.
                                        

                        1998 DIRECTORS STOCK OPTION PLAN
                                        

                          As Adopted October 31, 1997



     1.  Purpose.  This 1998 Directors Stock Option Plan (this "Plan") is
established to provide equity incentives for certain nonemployee members of the
Board of Directors of VeriSign, Inc., (the "Company"), who are described in
Section 6.1 below, by granting such persons options to purchase shares of stock
of the Company.

     2.  Adoption and Stockholder Approval.  After this Plan is adopted by the
Board of Directors of the Company (the "Board"), this Plan will become effective
on the time and date (the "Effective Date") on which the registration statement
filed by the Company with the Securities and Exchange Commission ("SEC") under
the Securities Act of 1933, as amended (the "Securities Act"), to register the
initial public offering of the Company's Common Stock is declared effective by
the SEC.  This Plan shall be approved by the stockholders of the Company,
consistent with applicable laws, within twelve (12) months after the date this
Plan is adopted by the Board.

     3.  Types of Options and Shares.  Options granted under this Plan shall be
non-qualified stock options ("NQSOs").  The shares of stock that may be
purchased upon exercise of Options granted under this Plan (the "Shares") are
shares of the Common Stock of the Company.

     4.  Number of Shares.  The maximum number of Shares that may be issued
pursuant to Options granted under this Plan (the "Maximum Number") is 125,000
Shares, subject to adjustment as provided in this Plan.  If any Option is
terminated for any reason without being exercised in whole or in part, the
Shares thereby released from such Option shall be available for purchase under
other Options subsequently granted under this Plan.  At all times during the
term of this Plan, the Company shall reserve and keep available such number of
Shares as shall be required to satisfy the requirements of outstanding Options
granted under this Plan; provided, however that if the aggregate number of
Shares subject to outstanding Options granted under this Plan plus the aggregate
number of Shares previously issued by the Company pursuant to the exercise of
Options granted under this Plan equals or exceeds the Maximum Number, then
notwithstanding anything herein to the contrary, no further Options may be
granted under this Plan until the Maximum Number is increased or the aggregate
number of Shares subject to outstanding Options granted under this Plan plus the
aggregate number of Shares previously issued by the Company pursuant to the
exercise of Options granted under this Plan is less than the Maximum Number.

     5.  Administration.  This Plan shall be administered by the Board or by a
committee of not less than two members of the Board appointed to administer this
Plan (the "Committee").  As used in this Plan, references to the Committee shall
mean either such Committee or the Board if no Committee has been established.
The interpretation by the Committee of any of the provisions of this Plan or any
Option granted under this Plan shall be final and binding upon the Company and
all persons having an interest in any Option or any Shares purchased pursuant to
an Option.

     6.  Eligibility and Award Formula.

         6.1  Eligibility.  Options shall be granted only to directors of the
              -----------                                                    
Company who are not employees of the Company or any Parent, Subsidiary or
Affiliate of the Company, as those terms are defined in Section 18 below (each
such person referred to as an "Optionee").

         6.2  Initial Grant.  Each Optionee who on or after the Effective Date
              -------------
first becomes a member of the Board will automatically be granted an Option for
15,000 Shares (an "Initial Grant") on the date such Optionee becomes a member of
the Board.

 
         6.3  Succeeding Grants.  On each annual anniversary of an Optionee's
              -----------------                                              
Initial Grant (or previous grant from the Company outside this Plan if such
Optionee was ineligible to receive an Initial Grant) provided the Optionee is a
member of the Board on such anniversary date and has served continuously as a
member of the Board since the date of such Optionee's Initial Grant or previous
grant, as the case may be, the Optionee will automatically be granted an Option
for 7,500 Shares (a "Succeeding Grant").

     7.  Terms and Conditions of Options.  Subject to the following and to
Section 6 above:

         7.1  Form of Option Grant.  Each Option granted under this Plan shall
              --------------------
be evidenced by a written Stock Option Grant ("Grant") in such form (which need
not be the same for each Optionee) as the Committee shall from time to time
approve, which Grant shall comply with and be subject to the terms and
conditions of this Plan.

         7.2  Vesting.  The date an Optionee receives an Initial Grant or a
              -------                                                      
Succeeding Grant is referred to in this Plan as the "Start Date" for such
Option.

              (a) Initial Grants.  Each Initial Grant will vest as to six and
                  --------------
one-fourth percent (6.25%) of the Shares on each three-month anniversary of the
Start Date for such Initial Grant, so long as the Optionee continuously remains
a director or, as determined by the Board in the Initial Grant or the Succeeding
Grant, a consultant of the Company.

              (b) Succeeding Grants.  Each Succeeding Grant will vest as to six
                  -----------------
and one-fourth percent (6.25%) of the Shares on each three-month anniversary of
the Start Date for such Succeeding Grant, so long as the Optionee continuously
remains a director or, as determined by the Board in the Initial Grant or the
Succeeding Grant, a consultant of the Company.

         7.3  Exercise Price.  The exercise price of an Option shall be the Fair
              --------------                                                    
Market Value (as defined in Section 18.4) of the Shares, at the time that the
Option is granted.

         7.4  Termination of Option.  Except as provided below in this Section,
              ---------------------
each Option shall expire ten (10) years after its Start Date (the "Expiration
Date"). The Option shall cease to vest when the Optionee ceases to be a member
of the Board or, as determined by the Board in the Initial Grant or the
Succeeding Grant, a consultant of the Company provided, however that if the
Optionee ceases to be a member of the Board or, as determined by the Board in
the Initial Grant or the Succeeding Grant, a consultant of the Company due to
death or total and permanent disability, the vesting of each Option shall
accelerate with respect to the number of shares that would have been vested on
the anniversary of the date of grant next following the Optionee's termination
date. The date on which the Optionee ceases to be a member of the Board or, as
determined by the Board in the Initial Grant or the Succeeding Grant, a
consultant of the Company shall be referred to as the "Termination Date". An
Option may be exercised after the Termination Date only as set forth below:

              (a) Termination Generally.  If the Optionee ceases to be a member
                  ---------------------
of the Board or, as determined by the Board in the Initial Grant or the
Succeeding Grant, a consultant of the Company for any reason except death of the
Optionee or disability of the Optionee (whether temporary or permanent, partial
or total, as determined by the Committee), then each Option then held by such
Optionee, to the extent (and only to the extent) that it would have been
exercisable by the Optionee on the Termination Date, may be exercised by the
Optionee no later than seven (7) months after the Termination Date, but in no
event later than the Expiration Date.

              (b) Death or Disability.  If the Optionee ceases to be a member of
                  -------------------
the Board or, as determined by the Board in the Initial Grant or the Succeeding
Grant, a consultant of the Company because of the death of the Optionee or the
disability of the Optionee (whether temporary or permanent, partial or total, as
determined by the Committee), then each Option then held by such Optionee to the
extent (and only to the extent) that it would have been exercisable by the
Optionee on the Termination Date, may be exercised by the Optionee (or 

                                      -2-

 
the Optionee's legal representative) no later than twelve (12) months after the
Termination Date, but in no event later than the Expiration Date.

     8.  Exercise of Options.


         8.1  Exercise Period.  Subject to the provisions of Section 8.5 below,
              ---------------                                                  
Options shall be exercisable as they vest.

         8.2  Notice.  Options may be exercised only by delivery to the Company
              ------
of an exercise agreement in a form approved by the Committee stating the number
of Shares being purchased, the restrictions imposed on the Shares and such
representations and agreements regarding the Optionee's investment intent and
access to information as may be required by the Company to comply with
applicable securities laws, together with payment in full of the exercise price
for the number of Shares being purchased.

         8.3  Payment.  Payment for the Shares purchased upon exercise of an
              -------
Option may be made (a) in cash or by check; (b) by surrender of shares of Common
Stock of the Company that have been owned by the Optionee for more than six (6)
months (and which have been paid for within the meaning of SEC Rule 144 and, if
such shares were purchased from the Company by use of a promissory note, such
note has been fully paid with respect to such shares) or were obtained by the
Optionee in the open public market, having a Fair Market Value equal to the
exercise price of the Option; (c) by waiver of compensation due or accrued to
the Optionee for services rendered; (d) provided that a public market for the
Company's stock exists, through a "same day sale" commitment from the Optionee
and a broker-dealer that is a member of the National Association of Securities
Dealers (an "NASD Dealer") whereby the Optionee irrevocably elects to exercise
the Option and to sell a portion of the Shares so purchased to pay for the
exercise price and whereby the NASD Dealer irrevocably commits upon receipt of
such Shares to forward the exercise price directly to the Company; (e) provided
that a public market for the Company's stock exists, through a "margin"
commitment from the Optionee and an NASD Dealer whereby the Optionee irrevocably
elects to exercise the Option and to pledge the Shares so purchased to the NASD
Dealer in a margin account as security for a loan from the NASD Dealer in the
amount of the exercise price, and whereby the NASD Dealer irrevocably commits
upon receipt of such Shares to forward the exercise price directly to the
Company; or (f) by any combination of the foregoing.

         8.4  Withholding Taxes.  Prior to issuance of the Shares upon exercise
              -----------------
of an Option, the Optionee shall pay or make adequate provision for any federal
or state withholding obligations of the Company, if applicable.

         8.5  Limitations on Exercise.  Notwithstanding the exercise periods set
              -----------------------                                           
forth in the Grant, exercise of an Option shall always be subject to the
following limitations:

              (a) An Option shall not be exercisable unless such exercise is in
compliance with the Securities Act and all applicable state securities laws, as
they are in effect on the date of exercise.

              (b) The Committee may specify a reasonable minimum number of
Shares that may be purchased upon any exercise of an Option, provided that such
minimum number will not prevent the Optionee from exercising the full number of
Shares as to which the Option is then exercisable.

     9.  Nontransferability of Options.  During the lifetime of the Optionee, an
Option shall be exercisable only by the Optionee or by the Optionee's guardian
or legal representative, unless otherwise determined by the Committee.  No
Option may be sold, pledged, assigned, hypothecated, transferred or disposed of
in any manner other than by will or by the laws of descent and distribution,
unless otherwise determined by the Committee.

     10. Privileges of Stock Ownership.  No Optionee shall have any of the
rights of a stockholder with respect to any Shares subject to an Option until
the Option has been validly exercised.  No adjustment shall be made for
dividends or distributions or other rights for which the record date is prior to
the date of exercise, except as 

                                      -3-

 
provided in this Plan. The Company shall provide to each Optionee a copy of the
annual financial statements of the Company at such time after the close of each
fiscal year of the Company as they are released by the Company to its
stockholders.

     11. Adjustment of Option Shares.  In the event that the number of
outstanding shares of Common Stock of the Company is changed by a stock
dividend, stock split, reverse stock split, combination, reclassification or
similar change in the capital structure of the Company without consideration,
the number of Shares available under this Plan and the number of Shares subject
to outstanding Options and the exercise price per share of such outstanding
Options shall be proportionately adjusted, subject to any required action by the
Board or stockholders of the Company and compliance with applicable securities
laws; provided, however, that no fractional shares shall be issued upon exercise
of any Option and any resulting fractions of a Share shall be rounded up to the
nearest whole Share.

     12. No Obligation to Continue as Director.  Nothing in this Plan or any
Option granted under this Plan shall confer on any Optionee any right to
continue as a director of the Company.

     13. Compliance With Laws.  The grant of Options and the issuance of Shares
upon exercise of any Options shall be subject to and conditioned upon compliance
with all applicable requirements of law, including without limitation compliance
with the Securities Act, compliance with all other applicable state securities
laws and compliance with the requirements of any stock exchange or national
market system on which the Shares may be listed.  The Company shall be under no
obligation to register the Shares with the SEC or to effect compliance with the
registration or qualification requirement of any state securities laws, stock
exchange or national market system.

     14. Acceleration of Options on Certain Corporate Transactions.  In the
event of (a) a dissolution or liquidation of the Company, (b) a merger or
consolidation in which the Company is not the surviving corporation (other than
a merger or consolidation with a wholly-owned subsidiary, a reincorporation of
the Company in a different jurisdiction, or other transaction in which there is
no substantial change in the stockholders of the Company or their relative stock
holdings and the Options granted under this Plan are assumed, converted or
replaced by the successor corporation, which assumption, conversion or
replacement will be binding on all Optionees), (c) a merger in which the Company
is the surviving corporation but after which the stockholders of the Company
(other than any stockholder which merges (or which owns or controls another
corporation which merges) with the Company in such merger) cease to own their
shares or other equity interests in the Company, (d) the sale of substantially
all of the assets of the Company, or (e) the acquisition, sale or transfer of
more than 50% of the outstanding shares of the Company by tender offer or
similar transaction, the vesting of all options granted pursuant to this Plan
will accelerate and the options will become exercisable in full prior to the
consummation of such event at such times and on such conditions as the Committee
determines, and must be exercised, if at all, within six months of the
consummation of said event.  Any options not exercised within such six-month
period shall expire.

     15. Amendment or Termination of Plan.  The Board may at any time terminate
or amend this Plan or any outstanding option, provided that the Board may not
terminate or amend the terms of any outstanding option without the consent of
the Optionee.  In any case, no amendment of this Plan may adversely affect any
then outstanding Options or any unexercised portions thereof without the written
consent of the Optionee.

     16. Term of Plan.  Options may be granted pursuant to this Plan from time
to time within a period of ten (10) years from the Effective Date.

     17. Certain Definitions.  As used in this Plan, the following terms shall
have the following meanings:

         17.1 "Parent" means any corporation (other than the Company) in an
unbroken chain of corporations ending with the Company if each of such
