           --------------------------------------
           from employment with the Company, no further installments of this
           option shall become exercisable and this option shall terminate after
           the passage of 90 days from the date employment ceases, but in no
           event later than the scheduled expiration date. In such a case, the
           Employee's only rights hereunder shall be those which are properly
           exercised before the termination of this option. If the Employee
           ceases to be employed by the Company, other than by reason of

           later than the scheduled expiration date. In such a case, the
           Employee's only rights hereunder shall be those which are properly
           exercised before the termination of this option.

     5.    Death. If the Employee dies while in the employ of the Company, this
           -----
           option may be exercised, to the extent of the number of shares with

           his death, by his estate, personal representative or beneficiary to
           whom this option has been assigned pursuant to Article 10, at any
           time within 180 days after the date of death, but not later than the

           date, whichever is the earlier, this option shall terminate and the
           only rights hereunder shall be those as to which the option was
           properly exercised before such termination.

           ----------------
           stated may be made in part at any time and from time to time within
           the above limits, except that this option may not be exercised for a
           fraction of a share unless such exercise is with respect to the final
           installment of stock subject to this option and a fractional share
           (or cash in lieu thereof) must be issued to permit the Employee to
           exercise completely such final installment.

     7.    Payment of Price. The option price is payable in United States
           ----------------

           ------------------------------------
           the Employee agrees that a purchase of shares under this option will
           not be made with a view to their distribution, as that term is used
           in the Securities Act of 1933, as amended, unless in the opinion of
           counsel to the Company such distribution is in compliance with or
           exempt from the registration and prospectus requirements of that Act,
           and the Employee agrees to sign a certificate to such effect at the
           time of exercising this option and agrees that the certificate for
           the shares so purchased may be inscribed with a legend to ensure
           compliance with that Act.

     9.    Method of Exercising Option. Subject to the terms and conditions of
           ---------------------------
           this Agreement, this option may be exercised by written notice to the
           Company, at the principal executive office of the Company, or to such
           transfer agent as the Company shall designate. Such notice shall
           state the election to exercise this option and the number of shares
           in respect of which it is being exercised and shall be signed by the
           person or persons so exercising this option. Such notice shall be
           accompanied by payment of the full purchase price of such shares, and
           the Company shall deliver a certificate or certificates representing
           such shares as soon as practicable after the notice shall be
           received. The certificate or certificates for the shares as to which
           this option shall have been so exercised shall be registered in the
           name of the person or persons so exercising this option (or, if this
           option shall be exercised by the Employee and if the Employee shall
           so request in the notice exercising this option, shall be registered
           in the name of the Employee and another person jointly, with right of
           survivorship) and shall be delivered as provided above to or upon the
           written order of the person or persons exercising this option. In the
           event this option shall be exercised, pursuant to Article 5 hereof,
           by any person or persons other than the Employee, such notice shall
           be accompanied by appropriate proof of the right of such person or
           persons to exercise this option. All shares that shall be purchased
           upon the exercise of this option as provided herein shall be fully
           paid and non-assessable.

     10.   Option Not Transferable. This option is not transferable or
           -----------------------
           assignable except by will or by the laws of descent and distribution.
           During the Employee's lifetime only the Employee can exercise this
           option.

     11.   No Obligation to Exercise Option. The grant and acceptance of this
           --------------------------------
           option imposes no obligation on the Employee to exercise it.

     12.   No Obligation to Continue Employment. The Company and any Related
           ------------------------------------
           Corporations are not by the Plan or this option obligated to continue
           the Employee in employment.

     13.   No Rights as Stockholder until Exercise. The Employee shall have no
           ---------------------------------------
           rights as a stockholder with respect to shares subject to this
           Agreement until a stock certificate therefor has been issued to the
           Employee and is fully paid for. Except as is expressly provided in
           the Plan with respect to certain changes in the capitalization of the
           Company, no adjustment shall be made for dividends or similar rights
           for which the record date is prior to the date such stock certificate
           is issued.

     14.   Capital Changes and Business Successions. It is the purpose of this
           ----------------------------------------
           option to encourage the Employee to work for the best interests of
           the Company and its stockholders. Since, for example, that might
           require the issuance of a stock dividend or a merger with another
           corporation, the purpose of this option would not be served if such a
           stock dividend, merger or similar occurrence would cause

                                      -4-
<PAGE>
 
           the Employee's rights hereunder to be diluted or terminated and thus
           be contrary to the Employee's interest. The Plan contains extensive
           provisions designed to preserve options at full value in a number of
           contingencies. Therefore, provisions in the Plan for adjustment with
           respect to stock subject to options and the related provisions with
           respect to successors to the business of the Company are hereby made
           applicable hereunder and are incorporated herein by reference. In
           particular, without affecting the generality of the foregoing, it is
           understood that for the purposes of Articles 3 through 5 hereof, both
           inclusive, employment by the Company includes employment by a Related
           Corporation as defined in the Plan.

     15.   Early  Disposition.  The Employee  agrees to notify the Company of 
           ------------------
           any disposition of any shares of Common Stock acquired on the
           exercise of this option within the two-year period beginning on the
           date of grant or within one year after the date of the transfer of
           such shares to the Employee. The Employee also agrees to provide the
           Company with any information which it shall request concerning any
           such disposition. Employees who receive incentive stock options will
           be disqualified under Section 422A of the Code from receiving the
           favorable income tax treatment otherwise available with respect to
           the exercise of such an option if they dispose of the stock received
           on exercise of the option within either of the one or two-year
           periods described in the preceding sentence.

     16.   Governing Law. This Agreement shall be governed by and interpreted in
           -------------
           accordance with the internal laws of Delaware.

IN WITNESS WHEREOF the Company and the Employee have caused this instrument to
be executed, and the Employee whose signature appears below acknowledges receipt
