Mr. Jeffrey J. Kaplan

Grandview, NY  10960

Dear Jeffrey:

        We are pleased to offer to you the full time, regular position of
Executive Vice President and Chief Financial Officer with Viewpoint Corporation
(the "Company"). You will work in our New York City headquarters and will report
to and work under the direction of Robert E. Rice, Chief Executive Officer.

        1.      Term. The initial term of your employment will commence on or
before February 15, 2001 (the "Commencement Date") and, unless earlier
terminated in accordance with this letter agreement, will continue until the
close of business on the day immediately preceding the third anniversary of the
Commencement Date. The term of your employment will automatically be extended
for successive one-year periods if neither party notifies the other in writing
at least 3 months prior to the then current term of employment that such term of
employment will not be extended for an additional one year term. In the event
that the Company elects not to renew this Agreement for an additional one-year
term to begin upon the third anniversary of your employment, or any subsequent
anniversary if the term has been extended, the Company will pay to you a
one-time severance payment equal to your then-current Base Salary (as defined
below).

        2.      Compensation. (a) Salary. You will be an exempt, salaried
employee. Your base salary will be $250,000 per year, earned and payable
according to the Company's standard payroll practices and subject to annual
review ("Base Salary").

                (b)     Annual Bonus. You will also participate in the Company's
Executive Incentive Compensation Plan as it exists from time to time. You will
receive at least $100,000 under the Company's Executive Incentive Compensation
Plan at the end of your first year of employment.

                (c)     Signing Bonus. In addition to the Base Salary and the
annual bonus, the Company will pay you a one-time signing bonus of $50,000 upon
commencement of employment.

        3.      Benefits. All benefits which the Company may now or hereafter
make available to employees of comparable status to you, will be made available
to you as well, on all of the same terms and conditions. You shall be entitled
to four weeks of paid vacation per annum.

        4.      Stock Option. You will be granted a stock option entitling you
to purchase 500,000 shares of Company common stock at an exercise price per
share equal to the closing price of Company common stock on the business day
immediately prior to your first day of employment (the "Stock Option").
Twenty-five percent of the shares subject to the Stock Option will vest on the
first anniversary of your hire date and, thereafter, the balance will vest at
the rate of 1/36th per month. The options shall expire 10 years from the date of
grant (the "Stock Option Expiration Date"). The Stock Option will be subject to
the Viewpoint Corporation 1996 Nonstatutory Stock Option Plan. Upon (a) a Change
in Control of the Company, (b) termination of your employment by the Company
without Cause, or (c) termination of your employment by you with Good Reason,
the shares subject to the Stock Option will become fully vested and will remain
exercisable until the earlier of five (5) years from the date of such event and
the Stock Option Expiration Date.

        5.      Certain Defined Terms. In addition to certain terms defined
elsewhere in this letter agreement, the following terms have the following
respective meanings:

                        "Change in Control of the Company" means and includes
                each of the following: (i) the acquisition, in one or more
                transactions, of beneficial ownership (within the meaning of

                (the "Exchange Act")) by any person or any group of persons who
                constitute a group (within the meaning of Section 13d-3 of the
                Exchange Act) of any securities of the Company such that, as a
                result of such acquisition, such person or group beneficially
                owns (within the meaning of Rule 13d-3 of the Exchange Act),
                directly or indirectly, more than fifty percent (50%) of the

                regular basis for a majority of the members of the Board; (ii) a
                change in the composition of the Board such that, during any

                (other than death) to constitute the majority of the Board;
                provided, however that any director who was not a director at
                the beginning of such period shall be deemed to be an Incumbent
                Director if such director was nominated for election or elected
                to the Board with the affirmative vote of a majority of the
                directors who then qualified as Incumbent Directors; (iii) the
                consummation of any merger or

                any other business combination (in one or more transactions,
                including, but not limited to a sale of all or substantially all
                of the assets) of the Company other than a transaction
                immediately following which the shareholders of the Company who
                own shares immediately prior to the transaction own, by virtue
                of their prior ownership of Company shares, at least 50% of the

                you to follow lawful directives of the Chief Executive Officer
                or Board of Directors of the Company, (b) conduct that is
                intentional and known by you to be harmful to the Company's best
                interests, or (c) your conviction for a felony or any crime
                involving dishonesty.

                        "Good Reason" means a breach by the Company of its
                obligations under this letter agreement, including any effective
                diminution of your duties

        6.      Loans/Special Bonus. (a) Date of Issuance; Interest Rates;
Security; Recourse. The Company will provide you with a loan in the amount of

of the Commencement Date (the "Second Loan"). Each loan will bear interest at
the Applicable Federal Rate under Section 1274(d) of the Internal Revenue Code
on the date the loan is made. The First Loan and the Second Loan will be secured
solely by the net, after-tax proceeds from the sale of the shares subject to the
Stock Option and any subsequent options to purchase Company common stock or
stock of any subsidiary or affiliate of the Company that may be granted to you
in the future. Unless you resign without Good Reason or are terminated by the
Company for Cause during the term of this letter agreement, the Company's
recourse to repayment of the First Loan and the Second Loan will be limited to
the Stock Option and any subsequent options that may be granted to you in the

                (b) Maturity Dates. The entire principal and interest of the
First Loan will be due on the fourth anniversary of the date the First Loan is
made. The entire principal and interest of the Second Loan will be due on the
fourth anniversary of the date the Second Loan is made.

                (c) Forgiveness. The Company will forgive repayment of the First
Loan and the Second Loan if, during the initial term or any additional term, (a)
there is a Change in Control of the Company, (b) the Company completes a
Qualifying Equity Financing (as defined below), or

(c) the Company completes a Qualifying Acquisition (as defined below). In the
event that, before the date that the Second Loan is disbursed, (a) there is a
Change in Control of the Company, (b) the Company completes a Qualifying Equity
Financing, or (c) the Company completes a Qualifying Acquisition, the Company
will not extend the Second Loan to you but will instead provide you with a
one-time special bonus of $375,000. In the Event any loans have been repaid and
(a), (b) or (c) occur during the initial term or any additional term, then a
special bonus equal to the repayment amount will be paid to you. For purposes of
this letter agreement, "Qualifying Equity Financing" means private or public
offerings of capital stock and/or securities convertible into capital stock of
the Company that result in greater than $25 million in aggregate gross proceeds

Commencement Date shall not be included in calculating the amount of proceeds
received by the Company. "Qualifying Acquisition" means an acquisition by the
Company of the business and operations of another company in which the aggregate

        7.      Consequences of a Change in Control. Upon a Change in Control of
the Company during the initial term or any additional term of this letter
agreement, the Company will (a) pay to you a lump sum payment equal to two times
your then current Base Salary, (b) the Stock Option will become fully vested and
exercisable until the earlier of five (5) years from the date of such Change in
Control and the Stock Option Expiration Date, (c) the First Loan and the Second
Loan (if made before such Change in Control) will be forgiven, and (d) if the
Second Loan had not been made before such Change in Control, the Company will
pay to you a one-time special bonus payment of $375,000.

        8.      Termination Without Cause or For Good Reason. If your employment
is terminated by the Company without Cause or terminated by you for Good Reason
before the expiration of the initial term or any additional term of this letter
agreement, (a) the Company will pay to you a lump sum payment equal to two times
your then current Base Salary, (b) the Stock Option will become fully vested and
exercisable until the earlier of five (5) years from the date of such
termination and the Stock Option Expiration Date, (c) the First Loan and the
