owned by you to the interests in such Competitor owned by such entity); (iii)
directly or indirectly soliciting, diverting, taking away, appropriating or
otherwise interfering with any of the customers or suppliers of the Company or

publish or make any disparaging statements about you, any Wilson Affiliates
controlled by you or any of their directors, officers or employees, or (b)

Terms And Conditions    
  

Section 1.    Scope and Service Description  

        This service is a Data Conference Service ("AT&T WebMeeting Service") that must be established as a Service within the family of AT&T TeleConference Services.
AT&T WebMeeting Service can be used in conjunction with other AT&T TeleConference Services to enable Customers to present, collaborate, share files/applications and modify documents via the Internet.
Specific Web Meeting Services Feature Descriptions are as set forth in Section 2 herein. 

2.    Feature Description  

        The following primary features are currently available for this service, as may be modified from time to time: 

        (a)  Presentation Mode.    This is targeted at "one to many" applications, and facilitates one-way transmission of
documents such as spreadsheets and slide presentations. For example, Keynote addresses, shareholder meetings, press conferences, and virtual classrooms can all be conducted in a "broadcast" mode. 

        (b)  Collaboration Mode.    This is targeted at applications involving smaller groups where participants can share
applications, exchange information, and transfer files. 

        (c)  Application Sharing.    A user can share a program or application running on one computer with other
participants in the conference. Participants can review the same data or information, and see the actions of the host (for example, editing a customer contract or browsing a web site.) Participants
can share Windows- based applications transparently without any special knowledge of the application capabilities. The person sharing the application can choose to collaborate with other people in a
call, and they can take turns editing or controlling the application. Only the person sharing the program needs to have the given application, e.g., Microsoft PowerPoint©, Installed on
their computer. 

        (d)  Online Polling.    Polling allows the host to create a survey prior to a conference or on an ad hoc basis as
the meeting progresses. Results can be tabulated immediately and if desired, shared with the entire audience. 

        (e)  File Transfer.    With this capability, a user can send a file in the background to one or all of the people on
the current call. A file can be sent to individual participants or to the group as a whole. Each person can then accept or decline receipt. The file transfer occurs in the background as everyone
continues sharing an application, using the whiteboard or chatting. 

        (f)    Whiteboard.    The whiteboard program is a multi-page, multi- user drawing application that enables users to
sketch diagrams, organization charts, or display other graphic information with people on a call. A remote pointer or highlighting tool can be utilized to point out specific contents or sections of
shared pages. This capability extends the application sharing feature by supporting ad hoc collaboration on a common drawing surface. 

        (g)  Chat.    Participants can type and transmit text messages to share common ideas or topics with other people, or
record meeting notes and action items as part of a collaborative process. Chat and its aspects are Host controlled options. There are three types: Chat to All, Private Chat to any other meeting
attendee, and Chat only to Host. 

        AT&T
reserves the right to modify features from time to time. Consult your AT&T Sales Representative for updates on feature modifications and enhancements. 

3.    Charges  

        AT&T reserves the right to modify charges for AT&T Web Meeting Service. Should AT&T elect to modify rates, AT&T and Customer will attempt to negotiate a revised
Web Meeting Service Order Attachment, which reflects the new Web Meeting Service rate, based on mutual agreement. Notwithstanding, anything contained herein to the contrary if Customer and AT&T are
unable to reach 

agreement on a modified rate for Web Meeting Services, AT&T will have no further obligation to provide service at the rates contained in this Attachment. 

        Charges
for AT&T Web Meeting Service are in addition to applicable charges for other AT&T TeleConference Service, which can be used in conjunction with Web Meeting Service. If
teleconference charges retire an AT&T minimum annual revenue commitment, then AT&T WebMeeting Service usage charges will contribute toward retirement of a minimum revenue commitment in any
TeleConference
specific Term Plan, TeleConference Service Order Attachment, in an AT&T Service Order Attachment, or other agreements. 

        There
are two, billing options available; details are as set forth in Section 6 herein. 

4.    Term  

        There is no term associated with this attachment. 

5.    Payment  

        Charges are billed and payable in U.S. Dollars. 

6.    Web Meeting Service Rates and Charges  

        There are two WebMeeting Service billing options: Cost Per Minute or Seat License billing. A checked box below indicates the agreed option: 

Schedule I

    ý Cost Per Minute  

        Web Meeting usage charges are $.33 cents per minute multiplied by the number of ports used in a WebMeetlng conference to determine the total usage minutes. Total
usage minutes are calculated for each WebMeeting conference. Charges for AT&T Web Meeting Service are in addition to applicable charges for AT&T TeleConference Service, which can be used in
conjunction with Web Meeting Service. 

        If
CUSTOMER utilizes the Multliocation Billing option from AT&T TeleConference Services, all locations are affected by this WebMeeting billing option. WebMeeting Cost Per Minute charges
can appear at applicable specific locatIon(s). 

        A
No Show fee will apply if zero ports are used after 30 minutes from the reserved start time of a WebMeeting. The fee is calculated by multiplying the cost per minute rate by the amount
of ports by 30 minutes. 

Schedule II

    o Seat License  

        Web Meeting usage charges are based on a calendar month subscription to Seat Licenses. Seat Licenses equate to concurrent CUSTOMER ports in use at any time and
provide unlimited usage to less than or equal to the total amount of Seat Licenses subscribed to for all concurrent WebMeeting conferences. Seats are available to all CUSTOMER users. The Web Meeting
charges are $         per Seat. CUSTOMER must subscribe to a minimum of             Seats. Initially, CUSTOMER will subscribe
to            Seats. CUSTOMER's monthly Seat
License rate equates to the amount of subscribed Seats multiplied by the amount per Seat. 

        If
concurrent CUSTOMER users exceed the amount of Seat Licenses, $1.00 per minute for each port in excess of the current amount of Seats subscribed to for the duration each
excessive port is used until total users equate to or are less than the amount of seats subscribed to. 

        CUSTOMER
changes to the amount of subscribed Seats must be provided with 15 days written notice to your AT&T TeleConference Account Executive. While the amount of Seats subscribed to can
increase or decrease, CUSTOMER cannot subscribe to less than the minimum number of Seats. 

        If
CUSTOMER utilizes Multilocation Billing option from AT&T TeleConference Services, all locations are affected by this WebMeeting billing option. All locations can use WebMeeting Seat
Licenses and all locations will contribute to the amount of concurrent users but all WebMeeting charges and credits are billed to the Headquarters location.

TERM PLAN TERMS AND CONDITIONS  

	•
	Rates
for Call Options are stabilized for the Term of the Agreement.

	•
	Regardless
of any stabilization of rates that may appear in this Attachment for the Services Provided, AT&T reserves the right to increase charges as a
result of expenses incurred by AT&T relating to regulatory assessments stemming from an order, rule or regulation of the Federal Communications Commission or other regulatory authority or court
having competent jurisdiction (including but not limited to payphone, PICC and USF related charges). 

Discontinuance Without Liability  

        This plan may be discontinued prior to the expiration of the specified term without liability under the following conditions: 

	•
	New
Plan:    "Customer" orders a new plan from AT&T with a revenue commitment and term equal to, or exceeding, the original commitment.
Discontinuance of the former plan and subscription to the new plan must be done concurrently. Subscription to the New Plan will supersede the existing agreement at any time during the life of the
current agreement. Entering into a new agreement with an equal to or higher revenue commitment does not imply that a customer has exercised the First Year Termination Without Liability clause. A new
plan may include; but is not limited to: a new standalone agreement for AT&T TeleConference Services, or inclusion inside an AT&T Network Agreement. 

	•
	First
Year Termination Without Liability:    "Customer" may, at any time during the first year, discontinue this plan without liability, provided
the "Customer": (1) has not discontinued another AT&T TeleConference Term Plan, or AT&T TeleConference Service with a revenue, volume and term commitment without liability in conjunction with
its order of this term plan; and (2) notified AT&T in writing at least 30 days prior to the anniversary of the term plan of its intent to discontinue the term plan. 

Discontinuance With Liability  

        A "Customer" who has ordered a plan, but discontinues service before the expiration of the term plan, is subject to the appropriate shortfall penalty for the
current year and any remaining years in the term plan upon discontinuance of the term plan. If the "Customer" has exercised the First Year Termination Without Liability Clause listed above, then this
clause would not apply. 

Expiration of the Term  

        The Customer's obligation to AT&T automatically expires when the term plan ends. Unless the Customer notifies AT&T at least 90 days prior to the expiration of the
term, service thereafter will be provided at the Volume Discounts Plan III rates as specified in AT&T Business Service Guide (formerly Tariff FCC No. 1). 

Shortfall Penalty  

        If the "Customer" does not meet the Annual Revenue Commitment in any one year, the "Customer" will be billed the difference between the minimum annual revenue
commitment and the actual billed usage. In the event the customer has exercised the 'Discontinuance Clause With Out Liability during the first year", the shortfall penalty would not apply to the
current or remaining years. If the customer exercised the "New Plan" agreement, the new plan would supersede the previous agreement, and no shortfall penalty would apply for the previous agreement.
However, the terms and conditions do begin again with the new agreement and short fail penalties could apply as stated above.
