                               ANDREW CORPORATION

                                       and

                                 PATH TEL, INC.

                                                    Path Tel. Inc. - 16 May 1995


                               PURCHASE AGREEMENT
                                     between
                               ANDREW CORPORATION
                                       and
                                 PATH TEL, INC.

This Agreement is made this 1st day of July 1995, by and between Andrew
Corporation, a Delaware corporation, with its offices located at 10500 West
153rd Street, Orland Park, Illinois 60462, hereinafter referred to as "Seller",
and Path Tel, Inc., with its offices located at 6715 Kenilworth Avenue,
Riverdale, Maryland 20737, hereinafter referred to as "Buyer".

Buyer is engaged in the business of providing turnkey negotiation and relocation
services to operators ("Incumbents") of microwave facilities on certain radio
frequency bands referred to as the "2 GHz Band". Seller is in the business of
manufacturing and selling certain telecommunications products that Buyer would
like to purchase on a "reseller type" basis. Buyer would issue Purchase Orders
to Seller for products to be delivered to various Incumbent sites around the
United States. These Purchase Orders would be governed by the terms and
conditions contained in this Agreement. In addition, Seller agrees to sell
certain telecommunications products to Incumbent's when these products
(specially coded or otherwise readily identifiable) have been specifically
recommended by Buyer. These purchases, while not a part of this Agreement, will
be considered part of the Buyer's net volume of orders when determining the
discount levels in this Agreement.

1.    DEFINITIONS

      A.    Products. The "Products" to be purchased and sold pursuant to this
            Agreement are the HELIAX(R) cable, connectors, accessories,
            HELIAX(R) elliptical waveguide, Microwave Antennas, Pressurization
            Products, Towers and Shelters Products, identified in Andrew Catalog
            36, or in such subsequent version of the Catalog as may be published
            during the term of this Agreement. All Seller's Products will be new
            and unused. No refurbished, reconditioned or reused Products will be
            provided without the prior written consent of Buyer. Seller reserves
            the right to add, delete or revise any Product offered herein upon
            sixty (60) days prior written notice to Buyer. Any purchase order
            for deleted or revised Products accepted by Seller during this 60
            day notice period shall be completed in accordance with all order
            requirements, provided such order is scheduled to ship within 60
            days after order placement.

      B.    Preconfigured/Coded Products. In order to simplify Product design,
            order entry, and the aggregate order volume tracking of orders by
            Incumbents to determine Buyer discount levels, the parties shall
            jointly develop coding for standard products packaged in kits
            ("Kit") and preconfigured non-standard Products. Kits are packages
            of standard products that will encompass a complete antenna system
            including waveguide and accessories as listed in Exhibit A-3.
            Preconfigured nonstandard Products can be added to Exhibit A-3 as
            they are developed. Seller may offer Kits and these other jointly
            developed products only to Buyer and Incumbents.

      C.    Ship to Address. The "Ship to Address" shall mean any location
            designated by Buyer for the delivery of Products in accordance with
            the terms and conditions in this Agreement.

      D.    Site. The "Site" shall mean Incumbent's installation site.

                                                    Path Tel, Inc. - 16 May 1995

2.    EXCLUSIVITY

      Buyer will exclusively recommend Seller's Products. Buyer will reengineer
      each Incumbent's microwave link with a replacement system utilizing the
      Seller's Products, unless another manufacturer's products are specified by
      the Incumbent.

3.    PRODUCT PRICING

      A.    Standard Products. The purchase price of all standard Products sold
            under this Agreement are the prices set forth in the then-current
            Andrew U.S. and International Price List attached hereto as Exhibit
            A-1, less the applicable discount set forth in the Discount Schedule
            in Exhibit B except for VALULINE(R) Antennas which are shown at net
            prices in Exhibit A-2. The initial discount is based on a forecast
            of the total "Net Volume" of Product orders projected to be issued
            by Buyer plus Kits and other specially preconfigured or otherwise
            readily identifiable products ordered by Incumbents, and accepted
            and paid for during an average year during the first three years of
            this Agreement. "Net Volume" shall mean the total price of standard
            and non-standard Product orders, less freight charges, taxes and
            insurance costs, that Buyer purchases from Seller including any Kits
            and other specially preconfigured or otherwise readily identifiable
            Products that Incumbents purchase from Seller.

            The initial discount for the two option years of this Agreement will
            be based upon a projection of the average annual net volume of
            orders to be placed and paid for during these two years. This
            forecast shall be prepared six months prior to the commencement of
            this two year period.

            The three year and the two year forecasts shall be broken down into
            semi-annual periods. These forecasts shall be updated semi-annually
            in a separate letter signed by a corporate officer of Buyer and
            shall be reviewed with the Seller. In the event Seller makes a
            reasonable determination that projected volumes will not be
            achieved, Seller shall have the right, upon sixty (60) days written
            notice to Buyer, to adjust the Discount Schedule accordingly.

      B.    Non-Standard Products. Prices for non-standard Products, including,
            but not limited to, towers and shelters, shall be quoted in writing
            by Seller, based on the Product specifications requested by Buyer.
            Quoted prices for such non-standard Products shall remain valid for
            a period of sixty (60) days after the quotation date, unless
            otherwise agreed to in writing by Seller.

      C.    Preconfigured/Coded Products. Net prices for Kits shall be
            determined by the then current Andrew U.S. Price List for the
            specific standard products comprising the Kit less the applicable
            discount shown in Exhibit B. Standard and Non-standard products that
            are specially preconfigured shall be coded, described and priced at
            net as set forth in Exhibit A-3. Seller reserves the right to offer
            these Products at the net prices in Exhibit A-3 only to Incumbents
            which agree to mutually acceptable terms and conditions within a
            reasonable period of time.

      D.    Product Support. Seller will provide the following product support
            to assist Buyer in familiarizing Incumbents in use of Seller's
            Products when appropriate:

                                                    Path Tel, Inc. - 16 May 1995

            1.    Telephone support from the Seller's Technical Services
                  Departments.

            2.    Seller's literature, publications and catalogs.

      E.    Price List. Seller agrees to notify Buyer in writing of any change,
            modification or revision to the Price List at least sixty (60) days
            prior to the effective date of the price change. Buyer orders
            accepted by Seller during this 60 day notice period shall be exempt
            from the price change, provided such orders are scheduled to ship no
            later than 90 days after the effective date of the price change.

      F.    Taxes. Product prices do not include sales, use, privilege, excise
            or any other tax, duty, tariff or assessment that may arise from the
            sale of the Products pursuant to this Agreement. In the event Seller
            becomes liable to pay or bear the burden of any such tax, the amount
            shall be added to the purchase price of the Products and shall be
            paid for by Buyer. All applicable taxes charged to Buyer shall be
            listed as a separate line item on Seller's invoice. A request for
            sales tax exemption must be accompanied by a tax exemption
            certificate prior to Product shipment.

4.    INVOICING AND PAYMENT TERMS

      A.    Invoicing. Seller shall invoice Buyer for Products upon shipment.
            Seller agrees that all invoices shall be submitted in duplicate to
            the address designated by Buyer on its purchase order. Each invoice
            shall include: (i) Buyer's purchase order number; (ii) Seller's
            invoice number; (iii) the quantity and price of Products shipped;
            (iv) applicable sales or other tax; (v) applicable freight charges;
            and (vi) the total invoice cost.

      B.    Net Payment Terms. Payment for Products purchased under this
            Agreement shall be due within thirty (30) days after date of
            Seller's invoice. If Seller deems necessary in its sole discretion,
            Seller may require a reasonable down payment concurrent with the
            issuance of Buyer's Purchase Orders.

      C.    Credit Limit. Seller reserves the right in its sole discretion to
            establish a credit limit based on financial information provided by
            Buyer, as well as other information. This credit limit will place a
            ceiling on the amount of the Seller's outstanding order backlog with
            Buyer and the amount of payments due from Buyer. In such event,
            Seller shall notify Buyer in writing of the amount of the credit
            limit. Credit limits may be changed from time to time to reflect
            changes in Buyer's financial status.

      D.    Late Payment Fees. Undisputed invoices that are more than 30 days
            past due shall be assessed a service charge of 1.5% per month or the
            maximum legal rate permitted by Illinois law, whichever is lower.
            Seller reserves the right to reject Buyer's purchase orders or to
            withhold shipment of Products if Buyer's account is in arrears, and
            Buyer fails to issue payment to bring its account current and/or in
            compliance with its credit limits within five (5) days after
            Seller's written request for payment. Buyer acknowledges that Seller
            retains full security interest in all Products until Buyer renders
            payment in full, and upon request, agrees to execute any documents
            necessary to perfect Seller's security interest.

                                                    Path Tel, Inc. - 16 May 1995

            by Buyer.

      B.    Acceptance. Seller shall notify Buyer in writing of its acceptance,
            rejection or proposed modification of an order within ten (10) days

            No preprinted term or condition stated on any Buyer purchase order

            order, unless expressly agreed to in writing by an authorized
            representative of Seller.

      D.    Change Orders. When any change order causes an increase or decrease
            in the purchase order price or the time required for the performance
            of any obligation, Seller and Buyer shall negotiate as soon as
            possible an equitable adjustment in the purchase order price and/or
            delivery schedule. Buyer change orders shall be in writing and
            signed by its authorized representative.

7.    CANCELLATION OF ORDERS

      Buyer may cancel orders for standard Products without penalty, provided
      Buyer notifies Seller not less than thirty (30) days prior to the
      scheduled delivery date. Orders for standard Products canceled by Buyer
      within 30 days of the scheduled delivery date shall be subject to a 20%

      order prior to receipt of the cancellation notice, plus a reasonable

                                                    Path Tel, Inc. - 16 May 1995

            commercial practices. Products shall be shipped F.O.B. Seller's
            plant, Freight Prepaid and Billed. All transportation charges shall
            be billed to Buyer at actual cost and shall be listed as a separate
            line item on Seller's invoice. Buyer agrees to pay all such
            transportation costs. Title to and risk of loss of the Products sold
            to Buyer under Buyer's purchase order shall pass to Buyer upon
            delivery of the Products to the common carrier at Seller's plant.
            (Title to and risk of loss of products, including Kits, sold to
            Incumbents and Clients under their purchase orders shall pass to
            them as stated in the Seller's contract with such Incumbents or
            Clients.) Adequate access to the Ship to Address and proper
            facilities for offloading, staging, moving and handling of items
            shall be the responsibility of the Buyer.

      B.    Delivery Dates. Buyer will endeavor to minimize the different types
            of Antennas used. This will allow Andrew to produce larger volumes
            of similar antennas that will enhance their availability and
            delivery dates. Seller shall make every reasonable effort to comply
            with the delivery dates specified in Buyer's purchase orders.

      C.    Buyer Delayed Shipments. Any request by Buyer to delay shipment of a
            completed order for more than thirty (30) days shall result in the
            assessment of a storage charge of 1.5% of the invoice price per
            month. In addition, on the 31st day of a delayed shipment, title to
            the completed Products shall automatically pass to Buyer and Seller
            shall invoice Buyer in full for the completed order. Buyer agrees to
            pay the invoice in accordance with the payment terms set forth in
            Section 4 of this Agreement. Seller shall insure the Products
            against risk of loss until the Products are delivered to the Ship to
            Address.

9.    FORCE MAJEURE

      Seller shall not be liable for any delivery delays due to causes beyond
      its reasonable control, including, but not limited to, acts of God, acts
      of the public enemy, fires, floods, acts of any government, strikes,
      embargoes, acts of Buyer, its employees or agents, unusually severe
      weather conditions, inability to obtain raw products used in the Products
      or any other condition beyond the control and without the fault of Seller.
      In the event of any such contingency, Seller shall be given a reasonable
      period of time in which to complete the performance of its obligations. If
      such contingency continues in effect for a period in excess of ninety (90)
      days, either party may cancel the purchase order, or any undelivered
      portion thereof, without liability to the other party.

10.   FINAL ACCEPTANCE

      Buyer shall inspect the Products within thirty (30) days after delivery
      and shall notify Seller in writing of any nonconforming Products. Buyer's
      failure to notify Seller within this time period or its use of the
      Products shall constitute final acceptance of the Products and shall

                                                    Path Tel, Inc. - 16 May 1995

      Product in a prompt and reasonable time period and shall pay all
      transportation charges to ship the Product replacement to Buyer at the
      Site location.

      infringement of the Product and any part of it.

13.   LIMITATION OF LIABILITY

                                  Amendment One
                          To Purchase Agreement between

                                  Amendment Two
                          To Purchase Agreement between
                      Andrew Corporation and Path Tel, Inc.
                                Dated 1 July 1995

Whereas, Andrew Corporation and Path Tel, Inc. entered into a Purchase Agreement
on 1 July 1995; and

Whereas, Andrew Corporation and Path Tel, Inc. desire to amend such Agreement by
revising the Discount Schedule, Exhibit B of the Agreement;

Now, Therefore, Andrew Corporation and Path Tel, Inc. agree as follows:

1. Replace Section 3A of the Agreement with the following effective July 1,
1997. The purchase price of all standard Products sold under this Agreement are
the prices set forth in the then-current Andrew Price List attached hereto as
Exhibit A-l, less the applicable discount set forth in the Discount Schedule in
Exhibit B. The initial discount is based on a forecast of the total "Net Volume"
of Product orders projected to be issued by Buyer plus Kits and other specially
preconfigured or otherwise readily identifiable products ordered by Incumbents,
and accepted and paid for during an average year during the next three years of
this Agreement beginning 1 July 1997 (assumes that Agreement shall be extended
two additional years by Buyer according to Section 14). "Net Volume" shall mean
the total price of standard and non-standard Product orders, less freight
charges, taxes and insurance costs, that Buyer purchases from Seller including
any Kits and other specially preconfigured or otherwise readily identifiable
Products that Incumbents purchase from Seller.

The three year forecast shall be broken down into semi-annual periods. This
forecast shall be updated semi-annually in a separate letter signed by a
corporate officer of Buyer and shall be reviewed with the Seller. In the event
Seller makes a reasonable determination that the three year forecast will not be
achieved, Seller shall have the right, upon sixty (60) days written notice to
Buyer, to adjust the Discount Schedule accordingly.

2. Replace the Discount Schedule, Exhibit B of the Agreement, with the attached
Discount Schedule, effective 1 July 1997, whenever products are purchased for 2
Ghz relocation projects.

3. Delete the old ValuLine(R) Antenna Price List, Exhibit A-2. It is now
included in Exhibit A-l.

4. All other items of the Agreement remain unchanged.

In witness whereof, the parties hereto have executed this Amendment One as of
the date indicated below.
