                  subsidiaries.

Awards granted under the Plan may be Options, Restricted Stock or Restricted
Stock Units as determined by the Administrator at the time of grant. The Plan is
being established to permit Awards to Employees of Convedia following the
acquisition of Convedia by the Company pursuant to the Arrangement. The Plan is
intended to comply with the National Association of Securities Dealers, Inc.'s
("NASD") Marketplace Rule 4350 which provides an exception to the NASD
stockholder approval requirement for the issuance of securities with regard to
grants to new Employees of the Company, including grants to transferred
Employees in connection with a merger or other acquisition.

Plan is equal to 365,000 Shares. Any Shares subject to an Award shall be counted
against the numerical limits of this Section 3 as one Share for every Share
subject thereto.

      The Shares may be authorized, but unissued, or reacquired Common Stock.

      If an Award expires or becomes unexercisable without having been exercised
in full, or, with respect to Restricted Stock or Restricted Stock Units, is
forfeited to or repurchased by the Company, the unpurchased Shares (or for
Awards other than Options, the forfeited or repurchased Shares) which were
subject thereto shall become available for future grant or sale under the Plan
(unless the Plan has terminated). Shares that have actually been issued under
the Plan under any Award shall not be returned to the Plan and shall not become
available for future distribution under the Plan; provided, however, if unvested
Shares of Restricted Stock are repurchased by the Company or are forfeited to
the Company, such Shares shall become available for future grant under the Plan.
Shares used to pay the exercise price of an Option shall become available for
future grant or sale under the Plan. However, Shares used to satisfy tax
withholding obligations shall not become available for future grant or sale
under the Plan.

      4. ADMINISTRATION OF THE PLAN.

      (a) Powers of the Administrator. Subject to the provisions of the Plan and

      accordance with Section 2(q) of the Plan;

                                     - 3 -
<PAGE>

            (ii) to select the Employees to whom Awards may be granted
      hereunder;

            (iii) to determine whether and to what extent Awards or any
      combination thereof, are granted hereunder;

            (iv) to determine the number of Shares to be covered by each Award
      granted hereunder;

            (v) to approve forms of agreement for use under the Plan;

            (vi) to determine the terms and conditions, not inconsistent with
      the terms of the Plan, of any Award granted hereunder. Such terms and
      conditions include, but are not limited to, the exercise price, the time
      or times when Options may be exercised or other Awards vest (which may be
      based on performance criteria), any vesting acceleration or waiver of
      forfeiture restrictions, and any restriction or limitation regarding any
      Award or the shares of Common Stock relating thereto, based in each case
      on such factors as the Administrator, in its sole discretion, shall
      determine;

            (vii) to construe and interpret the terms of the Plan and Awards;

            (viii) to prescribe, amend and rescind rules and regulations
      relating to the Plan, including rules and regulations relating to
      sub-plans established for the purpose of qualifying for preferred tax
      treatment under foreign tax laws;

            (ix) to modify or amend each Award (subject to Section 8(c) and
      Section 15(b) of the Plan), including the discretionary authority to
      extend the post-termination exercisability period of Options longer than
      is otherwise provided for in the Plan;

            (x) to authorize any person to execute on behalf of the Company any
      instrument required to effect the grant of an Award previously granted by
      the Administrator;

            (xi) to allow Participants to satisfy all or part of their
      withholding tax obligations by electing to have the Company or Convedia,
      as the case may be, withhold from the Shares or cash to be issued upon
      exercise or vesting of an Award that number of Shares or cash having a
      Fair Market Value equal to the minimum amount required to be withheld (but
      no more). The Fair Market Value of any Shares to be withheld shall be
      determined on the date that the amount of tax to be withheld is to be
      determined. All elections by a Participant to have Shares or cash withheld
      for this purpose shall be made in such form and under such conditions as
      the Administrator may deem necessary or advisable;

            (xii) to determine the terms and restrictions applicable to Awards;

            (xiii) to impose such restrictions, conditions or limitations as it
      determines appropriate as to the timing and manner of any resales by a
      Participant or other subsequent transfers by a Participant of any Shares
      issued as a result of or under an Award, including without limitation, (A)
      restrictions under an insider trading policy, and (B) restrictions as to
      the use of a specified brokerage firm for such resales or other transfers;
      and

            (xiv) to make all other determinations deemed necessary or advisable
      for administering the Plan.

                                     - 4 -
<PAGE>

      (b) Effect of Administrator's Decision. The Administrator's decisions,
determinations and interpretations shall be final and binding on all
Participants and any other holders of Awards.

      5. ELIGIBILITY. Options, Restricted Stock and Restricted Stock Units may
be granted only to Employees.

      6. NO EMPLOYMENT RIGHTS. Neither the Plan nor any Award shall confer upon
a Participant any right with respect to continuing the Participant's employment
with the Company or its subsidiaries, nor shall they interfere in any way with
the Participant's right or the Company's or subsidiary's right, as the case may
be, to terminate such employment at any time, with or without cause or notice.

      7. TERM OF PLAN. The Plan shall become effective on the Closing Date and
shall continue in effect for a term of 10 years after such date.

      8. STOCK OPTIONS.

      (a) Term. The term of each Option shall be stated in the Notice of Grant;
provided, however, that the term shall be no longer than 10 years from the date
of grant.

      (b) Option Exercise Price. The per share exercise price for the Shares to
be issued pursuant to exercise of an Option shall be determined by the
Administrator and shall be no less than 100% of the Fair Market Value per Share
on the date of grant.

      (c) No Repricing. The exercise price for an Option may not be reduced.
This shall include, without limitation, a repricing of the Option as well as an
Option exchange program whereby the Participant agrees to cancel an existing
Option in exchange for an Option or other Award.

      (d) Waiting Period and Exercise Dates. At the time an Option is granted,
the Administrator shall fix the period within which the Option may be exercised
and shall determine any conditions which must be satisfied before the Option may
be exercised. In so doing, the Administrator may specify that an Option may not
be exercised until the completion of a service period or until performance
milestones are satisfied.

      (e) Form of Consideration. The Administrator shall determine the
acceptable form of consideration for exercising an Option, including the method
of payment. Subject to Applicable Laws, such consideration may consist entirely
of:

            (i) cash;

            (ii) check;

            (iii) other Shares which (A) in the case of Shares acquired upon
      exercise of an Option, have been owned by the Participant for more than
      six months on the date of surrender, and (B) have a Fair Market Value on
      the date of surrender equal to the aggregate exercise price of the Shares
      as to which said Option shall be exercised;

            (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 proceeds required to pay the exercise price;

                                     - 5 -
<PAGE>

            (v) a reduction in the amount of any Company liability to the
      Participant, including any liability attributable to the Participant's
      participation in any Company-sponsored deferred compensation program or
      arrangement;

            (vi) any combination of the foregoing methods of payment; or

            (vii) such other consideration and method of payment for the
      issuance of Shares to the extent permitted by Applicable Law; provided,
      however, that in no case will loans be permitted as consideration for
      exercising an Option hereunder.

      (f) Exercise of Option; Rights as a Stockholder. Any Option granted
hereunder shall be exercisable according to the terms of the Plan and at such
times and under such conditions as determined by the Administrator and set forth
in the Option Agreement.

      An Option shall be deemed exercised when the Company receives: (i) written
or electronic notice of exercise (in accordance with the Option Agreement) from
the person entitled to exercise the Option, and (ii) full payment for the Shares
with respect to which the Option is exercised. Full payment may consist of any
consideration and method of payment authorized by the Administrator and
permitted by the Option Agreement and the Plan. Shares issued upon exercise of
an Option shall be issued in the name of the Participant. Until the stock
certificate evidencing such Shares is issued (as evidenced by the appropriate
entry on the books of the Company or of a duly authorized transfer agent of the
Company), no right to vote or receive dividends or any other rights as a
stockholder shall exist with respect to the optioned stock, notwithstanding the
exercise of the Option. The Company shall issue (or cause to be issued) such
stock certificate promptly after the Option is exercised. No adjustment will be
made for a dividend or other right for which the record date is prior to the
date the stock certificate is issued, except as provided in Section 13 of the
Plan.

      Exercising an Option in any manner shall decrease the number of Shares
thereafter available for sale under the Option, by the number of Shares as to
which the Option is exercised.

      (g) Termination of Employment. If a Participant's employment with the
Company and its subsidiaries terminates, other than upon the Participant's death
or Disability, the Participant may exercise his or her Option within such period
of time as is specified in the Option Agreement to the extent that the Option is
vested on the date of termination (but in no event later than the expiration of
the term of such Option as set forth in the Option Agreement). In the absence of
a specified time in the Option Agreement, the vested portion of the Option shall
remain exercisable for three months following the Participant's termination. If,
on the date of termination, the Participant is not vested as to his or her
entire Option, the Shares covered by the unvested portion of the Option shall
revert to the Plan. If, after termination, the Participant does not exercise the
vested portion of his or her Option within the time specified by the
Administrator, the Option shall terminate, and the Shares covered by such Option
shall revert to the Plan.

      (h) Disability. If a Participant terminates employment with the Company
and its subsidiaries as a result of the Participant's Disability, the
Participant may exercise the vested portion of his or her Option for 12 months
following the Participant's termination (but in no event may the Option be
exercised later than the expiration of the term of such Option as set forth in
the Option Agreement). If, on the date of termination, the Participant is not
vested as to his or her entire Option, the Shares covered by the unvested
portion of the Option shall revert to the Plan. If, after termination, the
Participant does not exercise the vested portion of his or her Option within the
time specified herein, the Option shall terminate, and the Shares covered by
such Option shall revert to the Plan.

                                     - 6 -
<PAGE>

      (i) Death of Participant. If a Participant dies while employed by the
Company or any of its subsidiaries, the vested portion of the Option may be
exercised for 12 months following the Participant's death (but in no event may
the Option be exercised later than the expiration of the term of such Option as
set forth in the Option Agreement), by the Participant's designated beneficiary,
provided such beneficiary has been designated prior to the Participant's death
in a form acceptable to the Administrator. If no such beneficiary has been
designated by the Participant, then the vested portion of such Option may be
exercised by the personal representative of the Participant's estate or by the
person(s) to whom the Option is transferred pursuant to the Participant's will
or in accordance with the laws of descent and distribution. If the vested
portion of the Option is not so exercised within the time specified herein, the
Option shall terminate, and the Shares covered by such Option shall revert to
the Plan.

      9. RESTRICTED STOCK.

      (a) Grant of Restricted Stock. Subject to the terms and conditions of the
Plan, Restricted Stock may be granted to Participants at any time as shall be
determined by the Administrator, in its sole discretion. The Administrator shall
have complete discretion to determine (i) the number of Shares subject to a
Restricted Stock Award granted to any Participant, and (ii) the conditions that
must be satisfied, which typically will be based on continued provision of
services but may include a performance-based component, upon which is
conditioned the grant, vesting or issuance of Restricted Stock.

      (b) Other Terms. The Administrator, subject to the provisions of the Plan,
shall have complete discretion to determine the terms and conditions of
Restricted Stock granted under the Plan. Restricted Stock grants shall be
subject to the terms, conditions, and restrictions determined by the
Administrator at the time the stock is awarded. Any certificates representing
the Shares of Restricted Stock awarded shall bear such legends as shall be
determined by the Administrator.

      (c) Restricted Stock Award Agreement. Each Restricted Stock grant shall be
evidenced by an agreement that shall specify the purchase price (if any) and
such other terms and conditions as the Administrator, in its sole discretion,
shall determine; provided, however, if the Restricted Stock grant has a purchase
price, such purchase price must be paid no more than 10 years following the date
of grant.

      10. RESTRICTED STOCK UNITS.

      (a) Grant of Restricted Stock Units. Subject to the terms and conditions
of the Plan, Restricted Stock Units may be granted to Participants at any time
as shall be determined by the Administrator, in its sole discretion. The
Administrator shall have complete discretion to determine (i) the number of
Shares subject to a Restricted Stock Unit Award granted to any Participant, and
(ii) the conditions that must be satisfied, which typically will be based on
continued provision of services but may include a performance-based component,
upon which is conditioned the grant or vesting of Restricted Stock Units. Under
Restricted Stock Units, the Company will issue Shares to the Participant only if
certain vesting conditions are satisfied. Until the Shares are issued, a
Participant receiving Restricted Stock Units shall have no rights as a
stockholder of the Company.

      (b) Other Terms. The Administrator, subject to the provisions of the Plan,
shall have complete discretion to determine the terms and conditions of
Restricted Stock Units granted under the Plan. Restricted Stock Unit grants
shall be subject to the terms, conditions, and restrictions determined by the
Administrator at the time the Restricted Stock Unit is awarded.

      (c) Restricted Stock Unit Award Agreement. Each Restricted Stock Unit
grant shall be evidenced by an agreement that shall specify such terms and
conditions as the Administrator, in its sole discretion, shall determine.

      11. LEAVES OF ABSENCE. Unless the Administrator provides otherwise or
except as otherwise required by Applicable Laws, vesting of Awards granted
hereunder shall continue during a medical, family or military leave of absence
whether paid or unpaid, or during any other leave of absence approved by the
Administrator.

      12. NON-TRANSFERABILITY OF AWARDS. Unless determined otherwise by the
Administrator, an Award may not be sold, pledged, assigned, hypothecated,
transferred, or disposed of in any manner other than by will or by the laws of
descent or distribution and may be exercised, during the lifetime of the
recipient, only by the recipient. If the Administrator makes an Award
transferable, such Award shall contain such additional terms and conditions as
the Administrator deems appropriate; provided, however, no Option shall in any
event be transferable for value.

      13. ADJUSTMENTS UPON CHANGES IN CAPITALIZATION.

      (a) Adjustments. Except to the extent that such adjustments would require
action by the stockholders of the Company, the number of shares of Common Stock
covered by each outstanding Award, the number of shares of Common Stock which
have been authorized for issuance under the Plan but as to which no Awards have
yet been granted or which have been returned to the Plan upon cancellation or
expiration of an Award, as well as the price per share of Common Stock covered
by each such outstanding Award shall be proportionately adjusted for any
increase or decrease in the number of issued Shares resulting from a stock
split, reverse stock split, stock dividend, combination or reclassification of
the Common Stock, or any other increase or decrease in the number of issued
Shares effected without receipt of consideration by the Company; provided,
however, that conversion of any convertible securities of the Company shall not
be deemed to have been "effected without receipt of consideration." Such
adjustment shall be made by the Administrator, whose determination in that
respect shall be final, binding and conclusive. Except as expressly provided
herein, no issuance by the Company of shares of stock of any class, or
securities convertible into shares of stock of any class, shall affect, and no
adjustment by reason thereof shall be made with respect to, the number or price
of shares of Common Stock subject to an Award.

      (b) Dissolution or Liquidation. In the event of the proposed dissolution
or liquidation of the Company, the Administrator shall notify each Participant
as soon as practicable prior to the effective date of such proposed transaction.
The Administrator in its discretion may provide for a Participant to have the
right to exercise his or her Option until 10 days prior to such transaction as
to all of the Awarded Stock covered thereby, including Shares as to which the
Award would not otherwise be exercisable. In addition, the Administrator may
provide that any Company repurchase option or forfeiture rights applicable to
any Award shall lapse 100%, and that any Award vesting shall accelerate 100%,
provided the proposed dissolution or liquidation takes place at the time and in
the manner contemplated. To the extent it has not been previously exercised
(with respect to Options) or vested (with respect to other Awards), an Award
will terminate immediately prior to the consummation of such proposed action.

      (c) Mergers, Reorganizations, Etc. In the event of a merger,
consolidation, plan of exchange, acquisition of property or stock, separation,
reorganization or liquidation to which the Company or a subsidiary is a party or
a sale of all or substantially all of the Company's assets (each, a
"Transaction"), the Committee shall, in its sole discretion and to the extent
possible under the structure of the Transaction, select one of the following
alternatives for treating outstanding Awards under the Plan:

                                     - 8 -
<PAGE>

            (i) Outstanding Awards shall remain in effect in accordance with
      their terms.

            (ii) Each outstanding Award shall be assumed or an equivalent Award
      shall be substituted by the successor corporation or a parent or
      subsidiary of the successor corporation. The amount, type of securities
      subject thereto and, if applicable, exercise price of the assumed or
      substituted Awards shall be determined by the Committee, taking into
      account the relative values of the companies involved in the Transaction
      and the exchange ratio, if any, used in determining shares of the
      successor corporation, or parent or subsidiary thereof, to be issued to
      holders of Shares. Unless otherwise determined by the Committee, the
      assumed or substituted Awards shall be vested only to the extent that the
      vesting requirements relating to Awards granted hereunder have been
      satisfied.

            (iii) The Committee shall provide a 30-day period prior to the
      consummation of the Transaction during which outstanding Options may be
      exercised to the extent then exercisable, and upon the expiration of such
      30-day period, all unexercised Options shall immediately terminate. The
      Committee may, in its sole discretion, accelerate the exercisability of
      Options so that they are exercisable in full during such 30-day period.
      The Committee may also, in its sole discretion, accelerate the vesting of
      Restricted Stock or Restricted Stock Unit Awards.

      14. DATE OF GRANT. The date of grant of an Award shall be, for all
purposes, the date on which the Administrator makes the determination granting
such Award, or such other later date as is determined by the Administrator;
provided, however, the date of grant of an Option shall be the date when the
Option is granted and its exercise price is set, consistent with Applicable Laws
and applicable financial accounting rules. Notice of the determination shall be
provided to each Participant within a reasonable time after the date of such
grant.

      15. AMENDMENT AND TERMINATION OF THE PLAN.

      (a) Amendment and Termination. The Board may at any time amend, alter,
suspend or terminate the Plan; provided, however, that the Board itself may not
make any amendment that would require approval by the Company's stockholders
under Applicable Law, regulation or rule or by the rules of any stock exchange,
including, without limitation, the rules of the Nasdaq System, on which the
Company's Common Stock is traded.

      (b) Effect of Amendment or Termination. No amendment, alteration,
suspension or termination of the Plan shall impair the rights of any
Participant, unless mutually agreed otherwise between the Participant and the
Administrator, which agreement must be in writing (or electronic format) and
signed by the Participant and the Company.

      (c) 409A Savings Clause. Notwithstanding any other provision of this Plan
or any Award Agreement to the contrary, the Board or the Committee may, in good
faith, amend the Plan or any outstanding Award Agreement without Participant
consent to the extent necessary, appropriate or desirable to comply with the
requirements under Section 409A of the Code or to prevent the Participant from
being subject to any additional tax or penalty under Section 409A of the Code,
while maintaining to the maximum extent practicable the original intent of the
Plan and the Award Agreement. Notwithstanding the foregoing, neither the Company
nor any subsidiary of the Company, nor the Committee, shall be liable to any
Employee or Participant if an Award is subject to Section 409A of the Code, or
the Participant otherwise is subject to any additional tax or penalty under
Section 409A of the Code.

      16. CONDITIONS UPON ISSUANCE OF SHARES.

      (a) Legal Compliance. Shares shall not be issued pursuant to the exercise
of an Award unless the exercise of the Award or the issuance and delivery of
such Shares shall comply with Applicable Laws and shall be further subject to
the approval of counsel for the Company with respect to such compliance.

      (b) Investment Representations. As a condition to the exercise or receipt
of an Award, the Company may require the person exercising or receiving such
Award to represent and warrant at the time of any such exercise or receipt that
the Shares are being purchased only for investment and without any present
intention to sell or distribute such Shares if, in the opinion of counsel for
the Company, such a representation is required.

      17. WITHHOLDING. The Company's obligations hereunder in connection with
any Award shall be subject to applicable U.S., federal, state and local
withholding tax requirements and the applicable withholding tax requirements of
any other country or jurisdiction.

      18. NO FRACTIONAL SHARES. No fractional Shares shall be issued or
delivered pursuant to the Plan or any Award, including on account of any action
under Section 13 of the Plan. In the case of Awards to Participants, the
Committee shall determine, in its discretion, whether cash shall be paid in lieu
of such fractional Shares or whether such fractional Shares or any rights
thereto shall be forfeited or otherwise eliminated.

      19. LIABILITY OF COMPANY.

      (a) Inability to Obtain Authority. The inability of the Company to obtain
authority from any regulatory body having jurisdiction, which authority is
deemed by the Company's counsel to be necessary to the lawful issuance and sale
of any Shares hereunder, shall relieve the Company of any liability in respect
of the failure to issue or sell such Shares as to which such requisite authority
shall not have been obtained.

      (b) Grants Exceeding Allocated Shares. If the Awarded Stock covered by an
Award exceeds, as of the date of grant, the number of Shares which may be issued
under the Plan, such Award shall be void with respect to such excess Awarded
Stock.

      20. RESERVATION OF SHARES. The Company, during the term of the Plan, will
at all times reserve and keep available such number of Shares as shall be
sufficient to satisfy the requirements of the Plan.
