                    SWITCH PORT LEASE AND SERVICE AGREEMENT


      This Switch Port Lease and Service Agreement ("Agreement") is hereby
entered into as of this 7th [handwritten] day of August [handwritten], 1996 and

(hereinafter "Lessee") having its principal offices at 1520 Eastlake Ave., E,
Suite 205, Seattle, Washington 98102 (collectively "Parties").

      The Parties agree as follows:

      1. Lease of Ports. Subject to the terms and conditions contained herein,
         --------------
Lessor hereby leases to Lessee, and Lessee hereby leases from Lessor the
quantity of DS-1 ports (set forth in Exhibit "A") on a Northern Telecom DMS-250
Switch (the "Switch"), located at 625 So. Grand Avenue, 7th Floor #711, (1
Wilshire Bldg.), Los Angeles, California 90017 to receive, process, and output
voice grade telephone message traffic.

      2. Term. This Agreement and the services contemplated hereunder shall not
         ----                                                                   
become effective until Lessee pays to Lessor $[*] representing first months
rental payment. Unless sooner terminated as provided herein, this Agreement
shall have a initial term of six (6) months (the "Initial Service Term")
commencing on the date set forth above. After the initial Service Term, service
shall automatically continue on a month-to-month basis (each month period is
referred to as an "Extended Term"), unless terminated by either party at the end
of the Initial Service Term or an extended Term, by giving at least 60 days
written notice of intent to terminate prior to the end of such Term. All terms
set forth herein shall apply to any 'Extended Term' of this Agreement.

      3. Charges, Payment and Billing. 
         ----------------------------

provided pursuant to this Agreement. As of the execution date of this Port
Agreement, the charges which apply are set forth in Exhibit "A" attached hereto.
Charges for ports will be paid in advance each month. In-use port charges
commence when the ports are activated in accordance with Section 6. Ports placed
in In-Use during a partial calendar month shall still be charged at a rate equal
to the full monthly In-Use port rate.

         b. Payment. Lessee agrees to remit any payment due to Lessor pursuant
to this Agreement on the first of each month (the "Due Date") . Any payment

received more than thirty (30) days after the first of the month shall
constitute a late payment resulting in a late payment charge of 1.5% of the
total invoice amount per month of the maximum legal rate, whichever is less. If
the total amount due on any invoice is not received by Lessor within fifteen
(15) days of the Due Date, Lessor may send Lessee written notice that all
services may be temporarily suspended due to non-payment. Lessor shall have the
right after ten (10) days following such notice to discontinue services pursuant
to this Agreement unless or until the total amount due including late payment
charges is paid in full by Lessee.

         c. Disputes. In the event of any billing disputes, Lessee will provide
to Lessor, prior to Due Date, a detailed presentation in writing of any disputed
charges. Notwithstanding such dispute Lessee shall pay any undisputed portion of
the disputed invoice. Any dispute by Lessee must be raised within sixty (60)
days of the Due Date, or such disputed claim is hereby waived. Disputes will be
resolved in accordance with the procedures outlined in paragraph 14(j).

         d. Additional Charges. Any applicable federal, state, or local use,
excise, sales, or privilege taxes, duties, or similar liabilities, chargeable to

Routing Tables") in the Switch which directs the flow of traffic to Lessee's
ports. Such routing procedure is to be implemented after a mutually acceptable
initial routing procedure has been approved by both parties. Lessee shall

codes to be entered into the Initial Routing Tables and shall specify the output
port(s) to which each NPA-NXX or country code, Lessee agrees that traffic bound
for that NPA-NXX or country code will be intercepted by the Switch and treated
with an announcement, or routed to a trunk group designated by Lessee. When
input to the Initial Routing Tables has been completed, Lessor shall provide
Lessee with a paper printout of the Initial Routing Tables. Lessee agrees:

                i.    to review the Initial Routing Tables to verify their 
accuracy;

                ii.   to notify Lessor in writing with five (5) business days 
of receipt of the printout of any error; and

                iii.  to specify changes needed to the Initial Routing Tables 
to Lessor in writing.


      Input to all tables will be considered correct and accepted by Lessee
unless Lessor is notified within five (5) business days otherwise.

         b. Routing Changes. Lessee may request changes to the Initial Routing
Tables resulting in revised routing tables (the "Revised Routing Tables"), which
may also be changed at the request of the Lessee.

      Lessor agrees to make requested changes at an extra charge to be paid in
advance by Lessee in accordance with the procedures and time-lines specified in
Exhibit "B," 

                                       4

 
attached hereto and made a part hereof. Lessee agrees to comply with the 
routing procedures specified in Exhibit B.

      8. Service Outage Recovery. Lessor agrees to work with Lessee to develop a
         ----------------------- 
mutually acceptable plan for alternative routing of Lessee traffic to mitigate
the outage in the event of a disaster or major Switch outage.

      9. Defaults and Remedies. It shall be a default under this Port Agreement,
         ---------------------

herein, Lessee shall give Lessor written notice of the breach. If such
deficiency or breach is not cured in five (5) days, Lessee shall have the right
to cancel this Agreement effectively immediately.

      10. Required Termination. Either party shall also have the right, whether
          --------------------
or not a default shall have occurred, to terminate this Agreement prior to the
expiration of the Initial Service Term or any Extended Term, upon no less than
thirty (30) days prior written notice to the other party if either party is
prohibited from furnishing any service related solely to this Agreement by order
of any court, the Federal Communications Commissions, or any other government
authority having jurisdiction as a result of any change in circumstance
occurring after creation of this Agreement; and in the event of early
termination under the paragraph, neither party shall have any continuing
obligation or liability to the other, except for such obligations or liabilities
for payment which existed at, or in respect of, services rendered through the

                                   EXHIBIT B

                    Routing Table Change Request Procedure

      Both parties to this Port Agreement dated 8/7, 1996,
                                                ---
understand that procedures should be established and followed to assure that
required routing changes are executed accurately and in a timely and cost
efficient manner. Lessor agrees to work with Lessee to customize the basic
procedures set forth below in ways which are mutually acceptable for achieving
these goals.

      1. Submitting Requests. Change requests must be made in writing and must
         -------------------
indicate exactly how the Routing Table data is to appear after the change.
Lessee may submit changes to Lessor via first-class mail, recognized courier or
facsimile transmission. In order to expedite processing, Lessor may request that
changes be sent to the attention of a particular individual or department and/or
that a particular form or format be used. Lessee shall pay for all changes
within 10 days of receipt of an invoice from Lessor.

      2. Acknowledging Receipt. Lessor shall acknowledge receipt of change
         --------------------- 
requests by facsimile transmission on the next business day after receipt of
Lessee's written request. If Lessor fails to acknowledge receipt of a change
request within one business day, Lessee should call Lessor to confirm receipt or
resubmit the request. Change requests will not be deemed received unless
acknowledged by Lessor.

      3. Timing of Input. Lessor shall review all change requests and contact
         ---------------
Lessee for clarification of the request, if applicable, within a reasonable
period of time after acknowledging receipt. A reasonable period of time for
reviewing the request generally will not exceed the next business day after the
receipt of the request. The change request will generally be completed within
the next business day following acknowledgment of Lessor's receipt of written
clarifications, if any from Lessee. Should Lessee request that any routing
change be completed by Lessor in less than the time interval specified above,
Lessor will use its best efforts to comply with Lessee's requests at an extra
charge. Lessee will always attempt to limit expedited changes to emergency
situations.

      4. Acknowledging Input. Within 1 business day following completion of
         -------------------
input, Lessor will send Lessee, via first-class mail, recognized courier or
facsimile transmission, a hard copy of print out of the changed routing tables
showing the contents before and after changes were made. Lessee shall review the
input to verify its accuracy. Completed changes will be considered correct and
accepted by Lessee unless Lessor is 

                                       12

 
notified otherwise within the next business day after the information was
received or five (5) days after it is sent, whichever is less.

      5. Data Base Management. Lessee shall be allowed direct input control via
         --------------------
password protected software of the routing, management, and authorization code
data base on the switch under a mutually acceptable procedure for security and
implementation. Any other user of the switch shall coordinate their input
process in conjunction with the Lessor procedures. However, such input control
and access does not allow Lessee to make changes to any data base or routing
