11. AGREEMENT

     1.   Grant of Option. Avistar Systems Corporation, a Nevada corporation
(the "Company"), hereby grants to the Optionee named in the Notice of Grant (the
"Optionee"), an option (the "Option") to purchase the total number of shares of
Common Stock (the "Shares") set forth in the Notice of Grant, at the exercise
price per share set forth in the Notice of Grant (the "Exercise Price") subject
to the terms, definitions and provisions of the 1997 Stock Option Plan (the
"Plan") adopted by the Company, which is incorporated herein by reference.
Unless otherwise defined herein, the terms defined in the Plan shall have the
same defined meanings in this Option.

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

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

          (i)  Right to Exercise.

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

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

               (c)  In no event may this Option be exercised after the date of
expiration of the term of this Option as set forth in the Notice of Grant, Part
I above.

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


                                      -2-
<PAGE>   3
to be exercised upon receipt by the Company of such written notice accompanied
by the Exercise Price.

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

     3.   Optionee's Representations. In the event the Shares purchasable
pursuant to the exercise of this Option have not been registered under the
Securities Act of 1933, as amended, at the time this Option is exercised,
Optionee shall, if required by the Company, concurrently with the exercise of
all or any portion of this Option, deliver to the Company his or her investment
representations as set forth in Section 4 of the Exercise Notice attached hereto
as Exhibit A.

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

          (i)  cash; or

         (ii)  check; or

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

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

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

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


                                      -3-
<PAGE>   4
of such termination, or if Optionee does not exercise this Option within the
time specified herein, the Option shall terminate.

     7.   Disability of Optionee. Notwithstanding the provisions of Section 6
above, in the event of termination of an Optionee's consulting relationship or
Continuous Status as an Employee as a result of his or her disability, Optionee
may, but only within sixty (60) days from the date of such termination (and in
no event later than the expiration date of the term of such Option as set forth
in the Option Agreement), exercise the Option to the extent otherwise entitled
to exercise it at the date of such termination; provided, however, that if such
disability is not a "disability" as such term is defined in Section 22(e)(3) of
the Code, in the case of an Incentive Stock Option such Incentive Stock Option
shall automatically convert to a Nonstatutory Stock Option on the day three
months and one day following such termination. To the extent that Optionee was
not entitled to exercise the Option at the date of termination, or if Optionee
does not exercise such Option to the extent so entitled within the time
specified herein, the Option shall terminate, and the Shares covered by such
Option shall revert to the Plan.

     8.   Death of Optionee. In the event of termination of Optionee's
Continuous Status as an Employee or Consultant as a result of the death of
Optionee, the Option may be exercised at any time within six (6) months
following the date of death (but in no event later than the date of expiration
of the term of this Option as set forth in Section 10 below), by Optionee's
estate or by a person who acquired the right to exercise the Option by bequest
or inheritance, but only to the extent the Optionee could exercise the Option at
the date of death.

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

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

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

                                      -4-

<PAGE>   5
Optionee shall satisfy his or her tax withholding obligation arising upon the
exercise of this Option out of Optionee's compensation or by payment to the
Company.

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

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

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

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

          (iv) Disposition of Shares. In the case of an NSO, if Shares are held
for at least eighteen months, any gain realized on disposition of the Shares
will be treated as long-term capital gain for federal and state income tax
purposes. In the case of an ISO, if Shares transferred pursuant to the Option
are held for at least one year after exercise and are disposed of at least two
years after the Date of Grant, any gain realized on disposition of the Shares
will also be treated as long-term capital gain for federal and state income tax
purposes. If Shares purchased under an ISO are disposed of within such one-year
period or within two years after the Date of Grant, any gain realized on such
disposition will be treated as compensation income (taxable at ordinary income
rates) to the extent of the difference between the Exercise Price and the
lesser of (1) the Fair Market Value of the Shares on the date of exercise, or
(2) the sale price of the Shares.

          (v)  Notice of Disqualifying Disposition of ISO Shares. If the Option
granted to Optionee herein is an ISO, and if Optionee sells or otherwise
disposes of any of the Shares acquired



                                      -5-
<PAGE>   6
pursuant to the ISO on or before the later of (1) the date two years after the
Date of Grant, or (2) the date one year after the date of exercise, the Optionee
shall immediately notify the Company in writing of such disposition. Optionee
agrees that Optionee may be subject to income tax withholding by the Company on
the compensation income recognized by the Optionee.

     13.  Entire Agreement; Governing Law. The Plan is incorporated herein by
reference. The Plan and this Option Agreement constitute the entire agreement of
the parties with respect to the subject matter hereof and supersede in their
entirety all prior undertakings and agreements of the Company and Optionee with
respect to the subject matter hereof, and may not be modified adversely to the
Optionee's interest except by means of a writing signed by the Company and
Optionee. This agreement is governed by Nevada law except for that body of law
pertaining to conflict of laws.

CAUSE.
