RE:      EMPLOYMENT TERMS

Dear Mr. Kaplan:

First Virtual Communications, Inc. (the "Company") is pleased to offer you the
position of Vice President of Finance and Chief Financial Officer, pursuant to
the terms of this letter agreement ("Agreement"), subject to the satisfactory
review of your references. Please respond to me by 5:00 p.m., West Coast time,
on December 20, 2002, at which time this offer will expire.

1.       DUTIES

You will be expected to perform various duties consistent with your position.
Upon acceptance of this offer, you will be an executive officer of the Company.
On the date that you are confirmed as a Section 16 Officer by action of the
Company's Board of Directors, you shall be covered by the Company's Executive
Officers' Change of Control Plan. As a Section 16 officer, you will report to
the Company's Chief Executive Officer, unless otherwise assigned by the Company.
Additionally you will be expected to achieve certain performance targets and
Company goals related to your specific job function ("ANNUAL PERFORMANCE
TARGETS"). Such Performance Targets shall be set and measured at the sole
discretion of the Company's President and Chief Executive Officer ("CEO").

2.       COMPENSATION

Your annual base salary will be $180,000 per year through December 31, 2003,
less payroll deductions and all required withholdings.  Upon achieving 100% of
your 2003 sales quota as established by the CEO, your target commissions
("Annual Target Commissions") will total $120,000, for an annual total target
compensation package of $300,000 for the calendar year 2003. Beginning January
1, 2004, your annual base salary will be reduced to $150,000. Your Annual
Target Commissions for 2004, upon achieving 100% of your sales quota for that
year, will be $150,000 for a total cash compensation target of $300,000 for
calendar year 2004.

You will be paid bi-weekly and you will be eligible for the following standard
Company benefits: medical insurance, paid time off, and holidays.  Details
about these benefit plans are available for your review in the Total Rewards
benefit guide delivered to you with this Agreement.  The Company may modify its
benefits and compensation packages from time to time, in its sole discretion,
as it deems necessary.

3.       STOCK OPTIONS

Upon commencement of employment and subject to approval of the Company's Board
of

<PAGE>

Directors, you will be granted a Stock Option under the Company's 1997 Equity
Incentive Plan to purchase 400,000 shares of the Company's Common Stock (the
"STOCK OPTION"). The Stock Option will be governed by and granted pursuant to a
separate Stock Option Agreement. The exercise price per share of the Stock
Option will be equal to the fair market value of the Common Stock established on
the date of grant, subject to approval by the Board of Directors. The Stock
Option will be subject to vesting so long as you continue to be employed with
the Company, according to the following schedule: twelve and one-half percent
(12 1/2%) of the shares subject to the Stock Option will vest on the last day of
the sixth full calendar month of your employment after the date of grant and the
remaining shares subject to the Stock Option will vest in equal installments at
the end of each monthly period thereafter.

If you have questions regarding the tax implications of the Stock Option or any
part of your compensation package, please consult with your own tax advisor.

4.       TERMINATION

Employment at First Virtual Communications is "at will." The Company may
terminate your employment at any time and for any or no reason, with or without
Cause or advance notice, by giving you written notice of such termination.
Similarly, you may terminate your employment with the Company at any time at
your election, in your sole discretion, for any or no reason upon written notice
to the Company. The term of your employment relationship may not be modified
except by a written agreement signed by the Chief Executive Officer or President
of the Company.

In the event that the Company terminates your employment without Cause (as
defined below), and upon your furnishing to the Company an executed release and
waiver of claims, you shall be entitled to receive severance payments in the
form of (i) a continuation of your base salary for a period of four months after
your date of termination, at the rate in effect on your date of termination, and
(ii) During the severance period, assuming that you are eligible for COBRA, you
shall be entitled to receive medical benefits for yourself and eligible
dependents paid for by the Company until the earlier of (a) three (3) months
after your date of termination, or (b) the date that you become eligible to

defined below) and (ii) the Company has a Change of Control, as defined in the
Company's Executive Officers' Change of Control Plan (the "Plan"), within sixty
(60) days following your termination date, then you shall be entitled to the
severance benefits set forth in Section 5 of the Plan, subject to all of the
other provisions of the Plan.

"CAUSE" means your: (i) gross negligence or willful misconduct in connection
with the performance of your duties to the Company that in the written
determination of a majority of the Board has not been cured within thirty (30)
days following receipt by you of written notice from

                                        2.

this Offer Letter and Employment Agreement, Proprietary Information and
Inventions Agreement or Indemnification Agreement by and between you and the
Company, which material breach has not been cured within thirty (30) days
following receipt by you of written notice from the Board identifying such
material breach.

If your employment is terminated for Cause, or you voluntarily terminate your
employment from the Company for any reason, all compensation and benefits will
cease immediately and you will receive no additional payment from the Company
other than your accrued base salary and accrued and unused vacation benefits
earned through your date of termination.

information, among other things.

In your work for the Company, you will be expected not to use or disclose any
