product purchases to enable GEI to achieve economies of scale and to meet
Customer's desired delivery schedule.

In consideration of the covenants and promises in the Agreement, Customer and

                  each item of Equipment, Software or Service ordered. All
                  purchase orders shall indicate that items are purchased or
                  licensed pursuant to the terms and conditions of this Volume
                  Purchase Agreement Contract #6706 dated September 29, 2000.

                           Exhibit E (Software License) which shall survive the
                           expiration of this Agreement and continue in effect
                           only for so long as the Software License associated
                           with the Capacity Enhancement Channels continues. The
                           marginal cost of additional capacity enhancement
                           channels will be ******; provided, however, Customer

                           license applies only to ****** provided to Customer
                           and that Customer shall pay hardware costs
                           (transmitters, receivers, etc.) and other software
                           charges (GL3000 subscriber upgrades, RFD node charges
                           etc.) for any additional charges associated with the
                           use of Capacity Enhancement Channels at prices to be
                           mutually agreed upon by the parties,

                              and

                  (2)      an Enterprise-wide license for Landing Strip Channels
                           pursuant to the terms of Exhibit E (Software License)
                           which shall survive the expiration of this Agreement
                           and continue in effect only for so long as the
                           Software License associated with the Landing Strip
                           Channels continues. Customer acknowledges and agrees
                           that this enterprise-wide license applies only to
                           ****** and that Customer shall pay hardware costs and
                           other software charges for any additional charges
                           associated with use of Landing Strip Channels at
                           prices to be mutually agreed upon by the parties.

                  ****** During the Term, Customer shall be allowed to purchase
                  additional licenses for the prices included in this Agreement.

         2.4.     For a fee agreed upon in advance, GEI, at Customer's request,
                  shall reconfigure the Equipment or Software.

         2.5.     Delay or Cancellation of Order and Early Shipments.

                  (a)      Delay of Order. At no charge to Customer, GEI shall
                           permit Customer to request a one time delay of all or
                           any part of a purchase order for Equipment, Software
                           or Services for no greater than 30 days from its
                           originally scheduled shipment date. If Customer
                           requests delay for the same Equipment, Services or
                           Software more than one time or the requested delay
                           date exceeds 30 days from its originally scheduled
                           shipment date, then the request shall be treated as a
                           cancellation and shall be subject to the terms and
                           conditions of Section 2.5(b). If Customer requests
                           such one-time delay, any associated shipment dates
                           for the items delayed, including those shipment dates
                           with penalties attached to them pursuant to Section
                           3.2 below, shall be extended to reflect the number of
                           days delayed.

                  (b)      Cancellation of Order.

                           (i)      Early Cancellation. At no charge to
                                    Customer, GEI shall permit Customer to
                                    cancel all or part of a purchase order for
                                    Equipment, Software or Services, provided
                                    (a) Customer requests such cancellation in
                                    writing, (b) GEI receives the written
                                    cancellation request at least ninety (90)
                                    days prior to the scheduled shipping date;
                                    and (c) GEI receives such written
                                    cancellation request by Customer no greater
                                    than thirty (30) days from the date GEI
                                    received the purchase order which is being
                                    partially or fully canceled by Customer's
                                    cancellation request.

                           (ii)     Late Cancellation. If Customer fails to
                                    comply with the requirements set forth in
                                    Subsection 2.5(b)(i), GEI shall charge and
                                    Customer agrees to pay a restocking fee of
                                    fifteen percent (15%) of the price of all
                                    Equipment, Services or Software that is
                                    canceled, plus all costs incurred by GEI due
                                    to GEI's return of (or inability to return)
                                    Equipment or Software supplied by third
                                    party vendors.

                  (c)      Early Shipments. Customer acknowledges and agrees
                           that GEI may ship an order up to ten (10) days in
                           advance of the proposed shipment date.

3.       SHIPMENT AND DELIVERY.

         3.1.     Shipment. GEI shall (a) arrange shipping and insurance and
                  shall bill Customer separately for the cost of such items and
                  (b) ship each item of the Equipment and Software FOB GEI's
                  location that supplied or assembled the Equipment or Software.
                  Delivery, for purposes of this Agreement, including, without
                  limitation, Section 3.2 below, shall be deemed to have
                  occurred when the Equipment or Software is received by the
                  carrier pursuant to the FOB terms of this Section 3.1.

         3.2.     Penalties. If GEI fails to deliver the Software items
                  identified in sections (a) or (d) of Exhibit G pursuant to the
                  dates established in those respective sections, then GEI shall
                  pay Customer penalties in the amount of one thousand dollars
                  ($1,000) per release (beta or commercial) per business day
                  that delivery is late, provided Customer has not caused the
                  delay. The total penalty for each Software item shall not
                  exceed ten percent (10%) of the purchase price for each
                  Software item. In no event shall the delivery of any other
                  Equipment or Software under this Agreement be subject to any
                  penalties. GEI shall pay penalties in the form of credits
                  applied against the amount owed by Customer for the purchase
                  of the Software giving rise to the penalty. These penalties
                  shall be Customer's sole and exclusive remedy as it relates to
                  GEI's obligations in this Section 3.2.

         3.3.     Acceptance. Acceptance of the Equipment and Software shall not
                  be unreasonably withheld and shall be deemed to have taken
                  place on the earliest to occur of: (a) thirty (30) days, plus
                  an additional four (4) days for shipment of the Equipment or
                  Software to Customer, have elapsed since the date of delivery
                  of the Equipment and Software pursuant to Article 3, without
                  Customer having given to GEI a written notice of a defect, or
                  (b) Customer notifies GEI in writing that Customer accepts the
                  Software, or (c) immediately upon Customer's commercial use of
                  the Software and Equipment in a fashion whereby Customer is or
                  would be entitled to receive any revenue from such use. If
                  Customer rejects the Software during the thirty (30) day
                  period after delivery of the Equipment and Software, it shall
                  provide written notice to GEI of the Defect in sufficient
                  detail to permit GEI to replicate the Defect, whereupon GEI
                  shall have thirty (30) days within which to remedy the Defect
                  and resubmit the Equipment and Software. Customer shall have a
                  fifteen (15) day period commencing on the date of such
                  resubmission within which to accept or reject the Software in
                  accordance with the procedures set forth above. If GEI cannot
                  resubmit the equipment or software within a reasonable time,
                  or if GEI cannot remedy the Defect after repeated efforts over
                  a period of at least sixty (60) days after the Equipment or
                  Software is resubmitted to Customer, then either party may
                  terminate that purchase order and the Equipment and Software
                  shall be returned; provided, however, Customer shall be deemed
                  to have purchased such Equipment and Software for purposes of
                  calculating Customer's volume commitment in Section 5.1. GEI
                  shall, within sixty (60) days upon return of the Equipment or
                  Software, (1) credit Customer's account, in the amount of any
                  purchase price actually paid, previously to GEI by Customer,
                  if Customer has any amounts owed to GEI; and, (2) if no
                  outstanding amounts are owed, then reimburse Customer for any
                  purchase price paid with respect to such Equipment or Software
                  rejected by Customer in accordance with the terms of this
                  Section 3.3. Upon return of the Equipment or Software and
                  payment of any related reimbursement, neither party shall bear
                  any further liability or obligation for such Equipment or
                  Software.

                  (a)      Shortages. Customer shall make any claim for
                           shortages (items invoiced but not delivered) promptly
                           upon discovery. In no case shall Customer make such
                           claims later than thirty (30) days after the delivery
                           date.

                  (b)      Returns for Non-Defective Items. Customer may return
                           non-defective Equipment or Software only if (i) the
                           shipment does not correspond to Customer's purchase
                           order or (ii) Customer orders the wrong Equipment or
                           Software and GEI agrees to exchange the delivered
                           Equipment or Software for different GEI equipment or
                           software. To return Equipment or Software, Customer
                           shall first obtain a return authorization, including
                           a tracking number and return address. Each item of
                           Equipment or Software being returned by Customer
                           shall have affixed to it a label showing the tracking
                           number of the return authorization. Customer shall
                           not return Equipment and Software under this
                           Subsection 3.4(b) unless the returned items are in
                           undamaged condition, in the original configuration,
                           and where appropriate, in the original packing.
                           Customer shall return Equipment or Software
                           authorized for return under this Subsection 3.4(b)
                           within thirty (30) days after the item is delivered.
                           GEI shall be responsible for shipping, insurance and
                           other expenses incurred in returning Equipment or
                           Software not corresponding to Customer's purchase
                           order; otherwise, Customer shall be responsible for
                           such charges.

                  (c)      Credits. Provided Customer complies with the
                           requirements set forth in Subsection 3.4(b), GEI
                           shall issue credits for returned items by issuing

                           in the Warranty attached hereto as Exhibit F.

4.       PRICES AND PAYMENT TERMS.

         4.1.     License Fees. In consideration of the undertakings of GEI and
                  the licenses granted herein, GEI agrees to invoice Customer
                  and Customer agrees to pay to GEI the license fees for the
                  Software in the amounts and at the times specified in this
                  Agreement, unless other financing arrangements have been
                  agreed upon and signed in writing by GEI and Customer. The
                  current prices for Software licenses are indicated on Exhibit
                  B; however, subject to the provisions of Section 5.4 herein
                  GEI reserves the right to modify GEI's prices for such items
                  at any time and from time to time without notice. GEI will
                  provide Customer with the most current price book upon
                  request.

         4.2.     Equipment. In consideration of the sale of the Equipment (if
                  any) by GEI under this Agreement, GEI agrees to invoice
                  Customer and Customer agrees to pay to GEI the fees for the
                  Equipment determined in accordance with this Agreement, unless
                  other financing arrangements have been agreed upon and signed
                  in writing by GEI and Customer. The current prices for items
                  of Equipment are indicated in the Equipment and Software price
                  book; however, subject to the provisions of Section 5.4
                  herein, GEI reserves the right to modify GEI's prices for such
                  items at any time and from time to time without notice. GEI
                  will provide Customer with the most current price book upon
                  request.

         4.3.     Customization Fees. If Customer requests GEI to customize the
                  Equipment or Software, then Customer and GEI shall enter into
                  a separate agreement which sets forth the terms, conditions
                  and pricing related to such customization. Unless otherwise
                  provided in an agreement signed by a GEI officer, GEI shall
                  solely own all intellectual property rights to all
                  customization of the Equipment or Software, except, if
                  applicable, the customization shall be licensed in accordance
                  with the Software License. For avoidance of doubt, GEI shall
                  have no ownership interest in third party equipment as
                  provided to GEI by Customer.

         4.5      Payment Dispute Process. If Customer disputes any invoice
                  amount in good faith, then Customer shall do the following
                  ("PAYMENT DISPUTE PROCEDURE") within thirty (30) days of
                  Customer's receipt of such invoice: (a) pay GEI the undisputed
                  amount of the invoice; and (b) provide GEI's Credit Department
                  a detailed written description of the disputed amount and the
                  basis for Customer's dispute with such amount. GEI may charge
                  a service fee equal to the lesser of (i) one and one half
                  percent (1-1/2%) per month or (ii) the highest interest rate
                  legally permitted on any unpaid amounts, unless such amounts
                  are ultimately determined not due in accordance with the
                  Payment Dispute Procedure. Customer shall cooperate with GEI
                  in resolving disputed invoice amounts and then promptly paying
                  amounts due, if any. Customer shall reimburse GEI for all
                  reasonable collection expenses. If Customer fails to follow
                  the Payment Dispute Process as set forth in this Section 4.5
                  for any invoice, then such invoice shall be considered an
                  undisputed invoice.

         4.6      Taxes. Prices represented herein and on all notifications
                  issued by GEI pursuant to this Agreement are exclusive of all
                  government excise, sales, service, use, occupational, or like
                  taxes and, accordingly, are subject to an increase equal in
                  amount to any tax GEI may be required to collect or pay upon
                  the licensing, delivery or installation of the Equipment,
                  Software or Services provided hereunder. Unless Customer
                  provides GEI with a valid resale exemption certificate prior
                  to shipment of the Equipment or Software or the performance of
                  the Service, Customer is responsible for payment of any taxes
                  resulting from or imposed upon this Agreement, the Software or
                  the Equipment delivered hereunder, except taxes based on GEI's
                  net income.

         4.7      Security Interest. Intentionally Deleted.

         4.8      Credit Facility. The Parties agree that only the Purchase
                  Orders received by GEI after June 13, 2000 and before August
                  1, 2000, which indicated that payment terms were subject to
                  this Agreement, shall be financed under the Promissory Note
                  and Security Agreement between the parties (dated March 21,
                  1997) ("Promissory Note"). In no event shall the aggregate
                  amount of the Purchase Orders to be financed pursuant to the
                  Promissory Note exceed ten million dollars ($10,000,000).

5.       PRICING AND COMMITMENTS.

         5.1      Volume Commitment. Customer agrees to purchase or license from
                  GEI a minimum amount of Equipment and Software in the
                  quantities and time frame as detailed in the table below:

                  ******

         5.2      Volume Purchase Discount. Provided Customer is not delinquent
                  on any of its obligations under the Agreement at the time of
                  shipping an order, unless in dispute pursuant to Section 4.5
                  (Payment Dispute Process) herein, GEI shall give Customer a
                  discount off the price of GEI-manufactured infrastructure
                  Equipment and GEI-owned Software. For the 2001 calendar year
                  (January 1, 2001 - December 31, 2001), . For the 2001 calendar
                  year (January 1, 2001 - December 31, 2001), the amount of the
                  discount shall be determined based upon the ******. Beginning
                  January 1, 2002(and on January 1st for each renewal year
                  thereafter), the amount of the discount offered to Customer
                  for the subsequent calendar year shall be based upon Customer
                  submitting to GEI a twelve-month "good faith" forecast of
                  purchase volume for that year for purchases of all GEI
                  manufactured or distributed equipment or software by Customer.
                  After an evaluation by both Parties of the probable purchase
                  volumes forecast by Customer, GEI shall provide the applicable
                  discount rate to Customer per the chart below. Additionally,
                  on or before the first working day of each calendar quarter,
                  Customer shall provide GEI with a "good faith" forecast of
                  purchase volume during the next six-month period. Customer
                  shall promptly provide GEI with revised "good faith" forecasts
                  upon the reasonable conclusion by either party that
                  adjustments are necessary to the prior forecast provided to
                  GEI. Promptly at the end of each

                  calendar year or the Term (if applicable) (but within thirty
                  (30) days after the end of the calendar year, the parties
                  shall "settle up" with each other. If Customer did not
                  purchase and pay at the purchase volume levels forecast for
                  that preceding calendar year which would have resulted in
                  Customer obtaining a lesser discount level, Customer shall owe
                  to GEI a Recapture Amount, which shall be equal to the
                  difference between the prices charged by GEI to Customer based
                  on Customer's forecast and the prices GEI would have charged
                  Customer based on actual purchase volume for the year. If
                  Customer purchases and pays for more than the purchase volume
                  forecast for the year and Customer would have been eligible
                  for a higher discount level, GEI shall owe to Customer a
                  Volume Credit, which shall be equal to the difference between
                  the prices Customer was charged and the applicable higher
                  discount level.. GEI shall pay the Volume Credit to Customer,
                  or Customer shall pay the Recapture Amount to GEI, as the case
                  may be, by adjusting the current year's discount level (based
                  on the forecast in accordance with the process described
                  above) by applying the highest discount level (if GEI owes
                  Customer a Volume Credit) or the lowest discount level (if
                  Customer owes GEI a Recapture Amount) provided for in the
                  Purchase Discount level listed in the table below, until GEI
                  has been paid the entire Recapture Amount or has paid the
                  entire Volume Credit, as the case may be. Customer shall be
                  responsible for issuing purchase orders or amending
                  previously-issued purchase orders to reflect the Recapture
                  Amount or Volume Credit adjustments discussed in the preceding
                  sentence. For avoidance of doubt, the party owing the
                  Recapture Amount or Volume Credit payable under this
                  Agreement, as the case may be, shall immediately pay in full
                  to the other party such amount upon the termination or
                  expiration of this Agreement; provided, however, GEI may set
                  off against any other monies owed by Customer to GEI.

                  The following tables sets forth the volume purchase levels and
                  the applicable discounts available depending on the year in
                  which the Equipment is invoiced:

                  For Equipment invoiced on or before 12/31/2000, the discount
                  shall be as follows:

                  ******

                  For Equipment shipped on or after 01/01/2001 the Volume
                  discount shall be as follows:

6.       TRAINING AND SUPPORT.

                  requested by Customer at a mutually agreeable location and
                  time. Training classes and pricing are attached as Exhibit "C"
                  to this Agreement. Training class fee paid by Customer to GEI,
                  including, without limitation, those fees paid by Customer to
                  GEI related to the Trainer Qualification Program, shall
                  contribute to the Volume Purchase requirements of Customer.

         6.2      Maintenance and Support.

                  a)       GEI will provide Customer with warranty Defect
                           support, subject to and in accordance with the terms
                           and procedures set forth in Exhibit F (Warranty) for
                           the Warranty Period. If Customer desires additional
                           support, Customer shall enter into GEI's standard
                           maintenance agreement, as in effect from time to time
                           (the "MAINTENANCE AGREEMENT"). Customer acknowledges
                           that if the parties are unable to reach accord on the
                           terms and provisions of the Maintenance Agreement,
                           then Customer shall be responsible for all such
                           maintenance and support except as set forth
                           specifically in this Agreement for warranty Defects.

                  either taken by itself or themselves together be adjudged to
                  go beyond what is reasonable in all the circumstances but
                  would be adjudged reasonable if any particular restriction or
                  restrictions were deleted or if any parts of the working
                  thereof were deleted, restricted or limited in a particular
                  manner then the said restrictions shall apply with such
                  deletions, restrictions or limitations as the case may be.

8.       INDEMNIFICATION.

         8.1      Infringement.

                  (a)      Defense. In the event of any claim or allegation
                           against Customer of infringement or misappropriation
                           of United States patent, copyright, trade secret, or
                           mask work rights by reason of the use by Customer of
                           the GEI-manufactured Equipment or GEI-owned Software
                           as permitted hereunder and provided that Customer
                           provides GEI prompt and timely written notice of the
                           claim or allegation, GEI will, at its expense, defend
                           such claim, and pay any costs, expenses and damages
                           actually awarded in connection therewith, including
                           the fees and expenses of the attorneys engaged by GEI
                           for such defense. GEI shall have the sole and
                           exclusive authority to defend and/or settle any such
                           claim or action. For purposes of Sections 8.1 (and
                           all subsections) and 8.2 (and all subsections)
                           herein, "GEI-manufactured Equipment" and "GEI-owned
                           Software" specifically excludes any third party
                           Equipment or Software. However, GEI agrees to
                           cooperate and assist Customer in defending third
                           party infringement claims against Customer that may
                           arise under this Agreement, but Customer shall be
                           solely responsible for its own defense costs and any
                           damages awarded or incurred as a result of such third
                           party infringement claims.

                  (b)      Certain Actions in Response to Infringement. Upon
                           GEI's sole determination, or if use of any
                           GEI-manufactured Equipment or GEI-owned Software is
                           prohibited, GEI, at its election shall, at its own
                           cost and expense, either (a) procure for Customer the
                           right to continue the use of such GEI-manufactured
                           Equipment or GEI-owned Software; (b) modify the
                           GEI-manufactured Equipment or GEI-owned Software, in
                           such a way that the use thereof does not infringe
                           upon the rights of third parties; but has similar
                           functionality; or (c) terminate this Agreement by
                           notice to Customer and refund to Customer the a
                           pro-rata amount of the license fees paid by Customer
                           for the infringing (or potentially infringing)
                           GEI-manufactured Equipment or GEI-owned Software,
                           based on a 5-year amortization schedule.

         8.2      LIMITATION OF INDEMNIFICATION FOR GEI.

                  (a)      No Liability. GEI shall have no liability or
                           obligation hereunder with respect to any infringement
                           claim (or defense thereof) if such infringement is
                           caused by (i) compliance with designs, guidelines,
                           plans or specifications of Customer or any third
                           party (including, without limitation, any customized
                           version GEI-manufactured Equipment or GEI-owned
                           Software); (ii) a modification made by any party
                           other than GEI; (iii) use of GEI-manufactured
                           Equipment or GEI-owned Software in an application or
                           environment other than as specified in the
                           Documentation; (iv) use of a non-current version if
                           the current version is non-infringing; or (v) the
                           combination, operation or use of any GEI-manufactured
                           Equipment or GEI-owned Software with other product(s)
                           not supplied by GEI. Customer agrees to indemnify and
                           hold harmless GEI from and against all liabilities,
                           obligations, costs, expenses and judgments, including
                           court costs, reasonable

                           BE LIMITED BY THE TERMS OF ARTICLE 7 HEREUNDER.

         8.3      By Customer. Except where GEI is obligated to indemnify
                  Customer under Section 8.1, and without limiting any other
                  obligation of Customer to indemnify GEI hereunder, (i)
                  Customer shall indemnify, defend and hold GEI harmless from

         10.1     Confidentiality. Customer and GEI shall each safeguard the
                  other's Confidential Information in the same manner as it

                  parties each agree that the amount of license or other fees
                  payable hereunder, and the payment terms, shall be deemed
                  Confidential Information for purposes of this Article 10. Each
                  party acknowledges that the disclosing party's Confidential
                  Information constitutes such party's valuable Confidential
                  Information and trade secrets. Each party expressly agrees and
                  acknowledges that it is entering into this Agreement, and

                  party's Confidential Information in whole or in part, except
                  as provided herein, without the prior express written
                  authorization of the disclosing party.

                  and non-use of Confidential Information of the disclosing
                  party shall not apply to any such information which (a) is
                  already known to the receiving party when received; (b) is or

                  unauthorized persons from having access thereto.

         10.4     Proprietary Legends. Customer shall not remove any copyright
                  notice or other proprietary or restrictive notice or legend
                  contained or included in any material provided by GEI, and

         14.1     Representations. Each party hereto represents and warrants
                  that this Agreement is valid and legally binding upon it and
                  enforceable in accordance with its terms. By submitting a
                  purchase order to GEI, Customer represents and warrants that
                  it (a) has the financial capability to pay the price and all
                  related charges for all items ordered and (b) shall maintain
                  that financial capability until that amount is fully paid. For
                  this purpose, "financial capability" means sufficient assets,
                  after deducting liabilities, to pay that amount without
                  becoming insolvent (as defined under any applicable law).

         14.2     Termination of Existing VPA. The Parties hereby expressly
                  terminate the Volume Purchase Agreement between the Parties
                  with an effective date of December 31, 1997. All purchase
                  orders received by GEI on or after June 1, 2000, shall be
                  deemed to be controlled by the terms and conditions herein
                  this Agreement.

         14.3     Force Majeure. Neither party shall be responsible for delays
                  or failures in performance resulting from causes beyond the
                  control of such party, including without limitation, any act
                  of God, fire, casualty, delay or disruption in transportation,
                  flood, earthquake, war, strike, lockout, epidemic, destruction
                  or shut-down of production facilities, shortage or
                  curtailment, riot, insurrection, governmental acts or
                  directives, or financial requirements or manufacturing
                  limitations imposed by third-party manufacturers, suppliers,
                  or vendors.

         14.4     Dispute Settlement. Except as otherwise provided in Section
                  14.3, if there is a dispute arising out of or related to this
                  Agreement, the parties shall (a) agree to negotiate in good
                  faith to settle the dispute in an amicable manner and (b) if
                  the parties are unable to agree within sixty (60) days of
                  dispute settlement discussions, the disputes arising out of or
                  in connection with this Agreement shall be referred to and
                  finally resolved by arbitration under the rules of the
                  American Arbitration Association in Atlanta, Georgia. The
                  language of arbitration shall be in English. The number of
                  arbitrators shall be one. Notwithstanding the preceding,
                  nothing herein in Section 14.3 shall restrict the right of
                  either party to apply to a court of competent jurisdiction for
                  a temporary restraining order, preliminary injunction, or
                  other equitable relief to preserve the status quo or prevent
                  irreparable harm, and for the right of GEI to bring suit in
                  federal court regarding violation of its copyright or other
                  proprietary rights.

         14.5     Permits and Authorizations. Each party is solely responsible
                  for obtaining any government licenses and authorizations
                  required to operate its business and for complying with the
                  rules and regulations of the government and regulatory
                  agencies. Neither GEI nor any of its employees or agents are
                  an agent for, nor a representative of Customer in matters
                  pertaining to the rules and regulations of any such
                  governmental agency.

         14.6     Export Provisions. Customer shall comply with all export laws
                  of the United States and Canada and agrees to not, whether

                  export or re-export any Equipment, Software, Documentation or
                  other GEI Confidential Information to any country in violation
                  of the laws of the United States or Canada. Customer agrees to
                  indemnify GEI against any liability incurred by GEI due to
                  Customer's violation of this Section 14.6.

         14.7     Publicity. Each party shall obtain the other party's prior
                  written consent before issuing any press release or otherwise
                  making any public announcement concerning this Agreement.

         14.8     Assignment. This Agreement shall not be assigned by either
                  party without the other party's advance written consent. This
                  Agreement shall be binding upon and inure to the benefit of
                  the parties, their successors and permitted assigns.

         14.9     Survival. After expiration or termination of this Agreement,
                  all provisions relating to payment shall survive until
                  completion of required payments. In addition to those
                  provisions which specifically provide for survival beyond
                  expiration or termination, all provisions contained in this
                  Article 14 and all provisions, if any, regarding ownership,
                  indemnification, warranty, liability and limits thereon, and
                  confidentiality and/or protection of proprietary rights and
                  trade secrets shall survive indefinitely or until the
                  expiration of any time period specified elsewhere in this
                  Agreement with respect to the provision in question.

         14.10    No Amendments. No amendment to this Agreement shall be
                  effective unless it is in a writing signed by a duly
                  authorized representative of each party. The term "Agreement",
                  as used herein, includes any future written amendments,
                  modifications, or supplements made in accordance herewith.

         14.11    No Nuclear, Aircraft or Life-Support Applications. None of the
                  items supplied by GEI are designed or intended for use as a
                  component in the maintenance or operation of a nuclear
                  facility, aircraft or air traffic system or a life-support or

                  any of the GEI-supplied items in such an application, the
                  Customer agrees to indemnify and hold GEI harmless against any
                  claim arising out of that application.

         14.12    Waiver. No term or provision hereof shall be deemed waived and
                  no breach excused, unless such waiver or consent shall be in
                  writing and signed by the party claimed to have waived or
                  consented. Any consent by any party to, or waiver of, a breach
                  by the other, whether express or implied, shall not constitute
                  a consent to, waiver of, or excuse for any other different or
                  subsequent breach.

         14.13    Severability. If any provision of this Agreement is held
                  illegal, void or unenforceable, to any extent, in whole or in
                  part, as to any situation or person, the balance shall remain
                  in effect and the provision in question shall remain in effect
                  as to all other persons or situations, as the case may be.

         14.14    Governing Law. This Agreement shall be deemed to have been
                  made in the State of Georgia and shall be governed by and
                  construed in accordance with the laws of the State of Georgia
                  exclusive of its rules governing choice of law and conflict of
                  laws.

         14.15    Entire Agreement. The Agreement and all schedules and exhibits
                  hereto and Amendment #1 (which is attached hereto for
                  reference as Exhibit H) constitutes the entire agreement
                  between the parties hereto concerning the subject matter of
                  the Agreement and supersedes and replaces all prior and
                  contemporaneous agreements and representations between such
                  parties concerning such subject matter. No person is
                  authorized for either party to make any agreement or
                  representation not expressly contained in the Agreement. No
                  change, termination, modification, or waiver of any term or
                  condition of the Agreement shall be valid unless in a writing
                  signed by each party hereto. The section headings contained in
                  the Agreement are for convenience of reference and shall not
                  in any way affect the meaning or interpretation of the
                  Agreement. This Agreement shall not create any rights in, or
                  be enforceable by, persons other than the parties hereto,
                  their successors and permitted assigns. If there is a conflict
                  between the General Terms and Conditions and the terms and
                  conditions of any Exhibit, the General Terms and Conditions
                  shall control, except that terms applicable to Third Party
                  Software shall control with respect to such Third Party
                  Software (including, without limitation, Section 10 of the
                  Software License). However, to the extent possible, the
                  General Terms and Conditions and the Exhibits shall be
                  construed as complementary to each other. The Agreement may be
                  executed in one or more counterparts, each of which shall be
                  deemed an original, but all of which together shall constitute
                  the same instrument.

IN WITNESS WHEREOF, each party has caused this Agreement to be executed by its
duly authorized representative, effective as of the Effective Date.

                                    EXHIBIT A

                                   DEFINITIONS

1.       DEFINITIONS. In addition to terms elsewhere defined in this Agreement,
         the following terms shall have the following meanings:

         1.1.     "Advanced Background Scanning" means support for
                  make-before-break sub-zone hand-off, registration flow control
                  in puddle sub-zones, robust pager state management in multiple
                  sub-zones, and fault-tolerant retry algorithm utilizing the
                  inherent redundancy in RF coverage.

         1.2.     "Ancillary Equipment" means any equipment ancillary or
                  peripheral to the Equipment, including antennae system
                  products, system consoles, remote system consoles, printers,
                  video screens and modems, that are either (i) not manufactured
                  by GEI or (ii) manufactured by GEI but listed in the Price
                  Book as a non-discountable item.

         1.3.     "Basic Background Scanning" ability to specify the location of
                  SCI frame pairs, the local scan list, signal strength
                  measurement parameters, and zone and sub-zone priorities as
                  defined in ReFLEX 2.7.

         1.4.     "Capacity Enhancement Channels (ReFLEX 25 2.7)" means a set of
                  features that can be enabled on a zone-by-zone basis to
                  enhance the capacity in large zones without a massive
                  build-out of transmitters and receivers, and without
                  degradation in the subscriber's experience. These features
                  include reverse channel hot spots, basic background scanning,
                  and advanced background scanning for ReFLEX25 version 2.7.

         1.5.     "Confidential Information" means the confidential and valuable
                  information of the respective parties which the parties desire
                  to protect against disclosure or competitive use and which is
                  in written or tangible form and designated either orally or in
                  writing as proprietary or confidential or is disclosed
                  visually or orally and is designated either orally or in
                  writing as being proprietary or confidential. GEI's
                  Confidential Information includes, without limitation, the
                  Software and Documentation.

         1.6.     "Data Unit Coasting" means the ability to schedule inbound
                  data units on the reverse channel during those frames when the
                  transmitters in the sub-zone are not transmitting ReFLEX
                  frames. Pagers that are scheduled to send such data units are
                  expected to have internal clocks that can "coast" through a
                  period with no forward channel activity while still
                  maintaining synchronization with the network.

         1.7.     "Defect" means any material error, problem, or defect in the
                  Equipment or Software which renders the Licensed Programs
                  inoperable or causes the Equipment or Software to fail to
                  perform substantially in accordance with the Specifications.

         1.8.     "Documentation" means the Specifications, drawings, user
                  manuals and other documents pertaining to the Software or
                  Equipment.

         1.9.     "Enterprise-wide license" is a pricing structure for only
                  Capacity Enhancing Channels and Landing Strip Channels in
                  which the respective software license is purchased whereby
                  instead of paying for each individual channel license, the
                  Customer pays one fee which covers the purchase of as many
                  channels as is needed for Customer's paging services.

         1.10.    "Equipment" means OEM Hardware, GEI-Manufactured Hardware and
                  other hardware components supplied by GEI to Customer pursuant
                  to this Agreement.

                  remainder of the Term.

         1.13.    "Forward Channel" means a database entry in the GL3100 that
                  represents a control or data channel within a ReFLEX sub-zone.
                  Each forward channel carries up to 6400 bits/second of data
                  from the network to paging devices.

         1.14.    "GEI-Manufactured Hardware" means GEI-manufactured hardware

                  that specifies the timing, content, and network address of
                  landing-strip re-director frames for a sub-zone. These frames
                  have the effect of re-directing pagers to their designated
                  control channels. A different landing-strip channel must be
                  configured for each sub-zone.

         1.16.    "Latency Enhancement Features" means a set of features that
                  can be enabled on a sub-zone-by-sub-zone basis to enhance
                  message latency. These features include time-of-day sub-zone
                  configuration, optimized forward channel work-ahead, reduced
                  inbound paging protocol delay, data in partially filled
                  control frames, pager class support for latency reduction,
                  auto collapse support as defined in ReFLEX 2.7, and priority
                  differentiation.

         1.17.    "Licensed Programs" means the object code (i.e.,
                  machine-readable) form of the Software programs developed and
                  owned by GEI for use in its paging systems, but excludes Third

      SOFTWARE PRICING FOR CAPACITY ENHANCEMENT ON WEBLINK'S REFLEX NETWORK

         ******

         Assumptions:

o        At least two capacity enhancement feature licenses are needed to
         activate capacity enhancement features in a sub-zone, one for the
         forward channel and the other for the reverse channel. Additional
         licenses are needed if there is more than one forward channel or more
         than one reverse channel in the sub-zone.

o        If there are multiple sub-zones in a zone, capacity enhancement
         features must be enabled in all or none of the sub-zones.

o        It is understood that capacity enhancement features are not necessary
         in order to operate a fully functioning landing-strip system.
         Conversely, it is also understood that landing strip is not necessary
         to operate the capacity enhancement features. The enterprise license
         shall include the features identified in the Definitions section above.

o        Pricing for the interference-based reverse channel reuse feature will
         be provided in a subsequent proposal.

     GEI a non-exclusive right to use computer software in object code form
     only, to practice inventions protected by issued patents or pending
     applications, and to use materials, subject to the provisions of this
     License Agreement. The Software Licenses, the User Material Licenses and

     referred to collectively as the "Licenses".

LICENSE FEES

2.1  The purchase price of the Equipment includes the fees for the Licenses (the
     "License Fees").

SOFTWARE LICENSES

3.1  GEI grants to the Customer a non-exclusive license or sublicense to use, in
     object code form only, the Software (the "Software Licenses"). The
     "Software" collectively means the software owned by GEI and itemized in
     GEI's Quotation/Sales Order Acknowledgment or contained in the equipment
     listed in GEI's Quotation/Sales Order Acknowledgment (the "Equipment") and

     software Licenses do not include any rights with respect to the source code
     form of the Software.

USER MATERIAL LICENSES

4.1  GEI may provide the Customer with materials, including drawings, diagrams,
     specifications, documentation, training manuals and user manuals, for the
     use and servicing of the Equipment and the Software (the "User Materials").
     GEI licenses or sublicenses the Customer the non-exclusive right to use the
     GEI owned User Materials and any third party owned User Materials in
     conjunction with the use and servicing of Equipment and Software (the "User
     Material Licenses"). GEI and the third parties reserve all rights in their
     respective User Materials.

NO TRANSFER OF SOFTWARE OR USER MATERIALS

5.1  The Customer shall not assign, transfer or sublicense the Software or the
     User Materials, whether separately or as part of a sale of the Equipment,
     without the prior written consent of GEI, which will not be unreasonably
     withheld.

ACKNOWLEDGMENT OF PATENT RIGHTS

6.1  The Customer acknowledges that various components of the Equipment and
     Software are the subject of one or more GEI patents or pending patent
     applications, or third party patents or pending patent applications under
     which GEI is licensed.

LIMITED, NON-EXCLUSIVE LICENSE UNDER PATENTS

7.1  GEI grants the Customer a non-exclusive right (the "Patent License") to
     practice the inventions protected by GEI's patents or pending patent
     applications or third party patents or pending patent applications that are
     embodied in either the Equipment or Software.

7.2  If any improvements to the Equipment or Software are claimed in any
     patents, or any patents issuing from any pending patent applications, owned
     by or licensed to the Customer, the Customer shall grant GEI a
     royalty-free, transferable license to make, use or sell, and to grant
     sublicenses to make, use or sell the Equipment, Software and improvements.
     The provisions of this Paragraph 7.2 shall survive the termination of this
     License Agreement.

TERMINATION OF LICENSES

8.1  The Licenses shall terminate if:

     (a)  the Equipment or Software is moved by the Customer outside of the
          country in which the Equipment and Software were first installed;

     (b)  the Equipment is sold, except as provided in Paragraph 8.2; or

     (c)  the Software is no longer used in connection with the Equipment.

     generally known to those outside the third party.

9.2  The Customer acknowledges that:

     (a)  the Software and all materials supplied in connection with the
          Software, including flow charts, object code and input data formats,
          contained Proprietary Information that has been developed by GEI or
          third parties at great expense and considerable effort of skilled
          professions, and is entrusted by GEI to the Customer under this
          License Agreement for use only as specifically set out in this License
          Agreement;

          Software, and all materials supplied or produced in connection with
          the Software, as an unpublished copyrighted work.

9.3  The Customer acknowledges the Proprietary Information has substantial value
     and that any use or disclosure of Proprietary Information by the Customer
     or its personnel in a manner not authorized by this License Agreement would
     likely cause GEI and the third parties irreparable damage that could not be
     fully remedied by monetary damages. So, the customer:

     (a)  shall maintain all Proprietary Information in strict confidence and
          shall neither use, copy or disclose, nor permit any Customer personnel
          to use, copy or disclose, the Proprietary Information for any purpose
          not specifically authorized under this License Agreement;

     (b)  shall ensure that the Software and all copies of it and User
          Materials, when not in use, are kept in a secure place, subject to
          restricted access only by those persons authorized to use and maintain
          the Equipment and Software;

     (c)  shall not decode, reverse engineer, reprint, transcribe or reproduce,
          in whole or in part, the Software and User Materials without the prior
          written consent of GEI;

     (d)  shall not in any way modify or enhance the Software without the prior
          written consent of GEI;

     (e)  shall not assign, timeshare or rent the Software; and

<PAGE>   22

****** ASTERISK REPRESENTS CONFIDENTIAL INFORMATION THAT HAS BEEN REDACTED

     (f)  grants to GEI the right to seek injunctive or other equitable relief
          from a court of competent jurisdiction to prevent unauthorized or
          unlawful action.

9.4  The Customer may make a reasonable number of copies of the object code
     version of the Software for backup purposes only.

9.5  The Customer's rights under this License Agreement shall terminate upon
     breach of any of the provisions set out in Section 9. The provisions of
     Paragraph 9.3 shall survive termination of this License Agreement. The
     Customer shall promptly return all copies of the Proprietary Information,
     including the Software and all User Materials provided for the Software,
     if:

     (a)  this License Agreement is terminated for any reason; or

     (b)  the Customer ceases control, possession or use of the Equipment, the
          Software or the User Materials.

9.6  To assist GEI in the protection of the proprietary rights of GEI and the
     third parties, and upon thirty (30) days written notice to Customer, the
     Customer shall permit representatives of GEI to enter the Customer's
     premises and inspect the Equipment and Software at any reasonable time.

REVISED VERSIONS OF THE SOFTWARE

10.1 The Customer agrees that if GEI provides revised versions of the Software
     to use in the Equipment, the revised versions shall be covered by the
     provisions of this License Agreement.

CERTAIN THIRD PARTY LICENSED PROGRAMS AND TERMS.

11.1 The Customer acknowledges that the items supplied by GEI may be or contain
     Software owned by third parties ("Third Party Software"). The Customer's
     continuing right to use Third Party Software and associated documentation
     is conditioned upon the Customer's agreement to abide by: (a) shrink
     wrapped or other agreements between the Third Party Software vendor and the
     Customer; (b) specifically indicated terms and conditions in this
     Agreement; and (c) terms and conditions that may from time to time be
     supplied by the Third Party Software vendors or GEI; provided, however,
     except as necessary to comply with applicable law, no subsequent change in
     the terms and conditions applicable to Third Party Software shall affect
     the Customer's license to use the Third Party Software previously supplied
     to the Customer by GEI if the Third Party Software is not thereafter
     updated or otherwise modified (including any new version or release level).

         -    Notwithstanding anything to the contrary in the VPA, GEI shall
              bear no responsibility for shipment delays due to Weblink
              Wireless' failure to comply timely with its obligations set forth
              in this letter agreement.

This understanding, which replaces the last sentence of Section 4.4(a) of the
VPA and modifies Section 4.5, may be changed at any time by the authorized
officers signing a mutually agreed-upon written agreement by WebLink Wireless
and GEI. The terms of this letter do not amend the terms of the VPA except as
explicitly stated herein. All the other terms of the VPA remain in full force
and effect. GEI agrees that WebLink Wireless' failure to meet the terms set
forth herein will not by itself constitute a default under that portion of
Section 8.1(f) of the Promissory Note that pertains to Weblink Wireless' default
of any agreement between Weblink Wireless and GEI. For avoidance of doubt, the
parties agree that the preceding sentence should not be construed, and shall not
in any way modify, the rights and remedies available to GEI associated with
Weblink Wireless' default in its performance of its obligations with any other
lender as set forth in Section 8.1 (f) (e.g., if Weblink Wireless' failure to
comply with its obligations hereunder causes Weblink Wireless to be in default
with its agreement with such other lender, then such would constitute an Event
of Default under the Promissory Note). Furthermore, except as explicitly
provided and then only to the extent provided herein, nothing herein shall
restrict or otherwise limit GEI's right to pursue any and all remedies available
at law or equity to enforce its rights under this letter agreement, the
Promissory Note and/or the VPA.

          The term "Commitment" contained in Section 9 of the Note is hereby
          deleted in its entirety and the following definition is inserted in
          lieu thereof:

               "'Commitment' means $10,000,000."

3.   MISCELLANEOUS.

     (a)  Reaffirmation. Except as modified herein, the Note remains in full
          force and effect, and Maker hereby expressly represents and warrants

         (i)  Power and Authority; Enforceability. Maker has the power and
              authority to execute and deliver this Amendment #3 and to perform
              the terms and conditions of the Note, as amended by this Amendment
              #3. The execution and delivery of this Amendment #3 by Maker and
              the performance of the Note, as amended by this Amendment #3, do
              not and will not violate any law, rule or regulations or
              constitute a breach of the articles, bylaws or corporate
              resolutions of Maker or any agreement to which Maker is a party or
              by which its assets are bound. The Note, as amended by this
              Amendment #3, constitutes a legal, valid and binding obligation of
              Maker enforceable in accordance with its terms.

        (ii)  No Default or Event of Default. There is no Default or Event of
              Default under the Note, as amended by this Amendment #3, and Maker
              is not in default in the performance, observance or fulfillment of
              any of the obligations, covenants or conditions contained in any
              other document or instrument executed or delivered in connection
              herewith or therewith.

IN WITNESS WHEREOF, Glenayre and Maker have caused this Amendment #3 to be duly
executed and delivered under seal by their duly authorized officers, all as of
