ITEM 5.  OTHER EVENTS.

        On January 14, 1999, NEXTLINK Communications, Inc. (the "Company") 
announced two transactions to acquire LMDS licenses granted by the  Federal 
Communications Commission (the "FCC").  The first transaction is the 
acquisition of WNP Communications, Inc. ("WNP") and the second is an 
agreement in principle with Nextel Communications, Inc. ("Nextel") to acquire 
the 50% interest in NEXTBAND, L.L.C. ("NEXTBAND") that the Company does not 
already own. Upon completion of the WNP merger, the Company will become the 
largest LMDS spectrum holder.  A copy of the press release announcing the 
agreement to acquire WNP and the agreement in principle with Nextel is 
attached hereto as Exhibit 99.1 and incorporated by reference herein.

        WNP COMMUNICATIONS, INC.  NEXTLINK Communications, Inc. (the 
"Company") and WNP Communications, Inc. ("WNP") entered into an Agreement and 
Plan of Merger, dated January 14, 1999 (the "Merger Agreement").  Pursuant to 
the Merger Agreement, WNP will be merged with and into a wholly-owned 
subsidiary of the Company (the "Merger").

        The total consideration to be paid by the Company will be $695 
million.  Of this amount, $152.9 million (representing the amount of the 
bidding credits claimed and utilized by WNP in the spectrum auction conducted 
by the FCC (the "LMDS Auction")) plus interest thereon will be paid to the 
FCC and the remainder will be paid to stockholders of WNP (the "Merger 
Consideration").  The Merger Consideration will consist of cash and, at the 
Company's election, shares of its Class A Common Stock ("Common Stock"), 
provided, however, that at least approximately $187 million of the Merger 
Consideration will be paid in cash.  If shares of Common Stock are issued in 
the Merger, holders of such shares will be entitled to certain demand and 
piggy-back registration rights following the Merger.

        Consummation of the Merger is subject to regulatory and other 
conditions, including without limitation, that (i) any waiting period (and 
any extension thereof) under the Hart-Scott-Rodino Act applicable to the 
Merger shall have expired or been terminated, (ii) the FCC shall have granted 
its consent and approval to the assignment of WNP's LMDS licenses to the 
Company, and  such approval shall be in full force and effect and shall have 
become final and (iii) the Securities and Exchange Commission shall have 
declared effective the Company's registration statement registering the 
shares of Common Stock to be issued as Merger Consideration, if any.  Certain 
conditions to consummation of the Merger may be waived by the Company or WNP.

        The foregoing summary of the Merger and the transactions contemplated 
in connection therewith does not purport to be complete and is qualified in 
its entirety by all of the terms and provisions of the Merger Agreement and a 
Registration Rights Agreement, copies of which are attached hereto as 
Exhibits 10.1 and 10.2 and incorporated by reference herein.  

        NEXTEL COMMUNICATIONS, INC.  In 1998, the Company and Nextel entered 
into a joint venture, NEXTBAND, with each of them holding a 50% interest.  On 
January 14, 1999, the Company announced an agreement in principle to acquire 
Nextel's interest in NEXTBAND.  The contemplated acquisition price for Nextel's
interest in NEXTBAND will be based on the same

value per megahertz per thousand POPs as was used to determine the value of 
the Merger Consideration in the WNP transaction.  No written agreements have 
been entered into between the Company and Nextel with respect to this 
transaction.

                  WHEREAS, the Consent and Indemnity Agreement of Stockholders
and the Consent and Indemnity Agreement of Preferred Stockholders each
constitute (i) an agreement to indemnify the Indemnified Parties pursuant to
Article VIII of this Agreement and (ii) an irrevocable power of attorney
designating Thomas H. Jones as the Stockholders' Representative hereunder, with
full power and authority (and exculpated from personal liability for all actions

contemplated by this Agreement and the Registration Rights Agreement on their 
behalf; and

                  WHEREAS, the Merger Consideration will consist of cash, and,
as Purchaser shall determine (the "PURCHASER SHARE ELECTION"), as provided
below, of shares of Purchaser's Class A Common Stock, $.02 par value ("PURCHASER
COMMON STOCK"), it being the intention of the parties, in the event that
Purchaser Common Stock forms part of the Merger Consideration, that the Merger
qualify for federal income tax purposes as a reorganization under the provisions
of Section 368(a)(2)(D) of the United States Internal Revenue Code of 1986 (the
"CODE"); and

                  WHEREAS, substantially all of the Company's assets consist of
cash and licenses granted by the United States Federal Communications Commission
(the "FCC") to use electromagnetic spectrum in the 28-31 GHz range ("LOCAL
MULTIPOINT DISTRIBUTION SERVICE" or "LMDS") purchased at a spectrum auction (the
"LMDS AUCTION") conducted by the FCC pursuant to its Second Report and Order
dated March 13, 1997 and its Orders on Reconsideration released on May 6, 1997,
September 12, 1997 and February 11, 1998 (such orders, together with other
applicable FCC rules, orders and policies, the "LMDS RULES"); and

                  WHEREAS, the Company, Purchaser and Merger Sub desire to make
certain agreements in connection with the transactions contemplated hereby.

                  NOW, THEREFORE, in consideration of the premises and of the
representations, warranties, covenants and agreements hereinafter set forth, the
parties hereto agree as follows:

                                   ARTICLE I.

                                   THE MERGER

                  1.1. THE MERGER. (a) At the Effective Time (as defined in
SECTION 1.2) and subject to and upon the terms and conditions of this Agreement
and the DGCL, the Company shall be merged with and into Merger Sub (the
"MERGER"), the separate corporate existence of the Company shall cease, and
Merger Sub shall continue as the surviving corporation (the "SURVIVING
CORPORATION").

                  (a)(b) The parties to the Merger shall file with the Secretary
of State of Delaware a certificate of merger substantially in the form attached
hereto as EXHIBIT C (the "CERTIFICATE OF MERGER") in order to comply in all
respects with the requirements of the DGCL and with the provisions of this
Agreement.

                  1.2. EFFECTIVE TIME. The Merger shall become effective at the
time of the filing of the Certificate of Merger


                                      -2-
<PAGE>

with the Secretary of State of Delaware in accordance with the applicable 
provisions of the DGCL. As soon as practicable after all of the conditions 
set forth in ARTICLE VI of this Agreement have been satisfied or waived by 
the party or parties entitled to the benefit of the same, the parties hereto 
shall cause the Merger to simultaneously become effective by making such 
filings at the closing of the Merger to be held at the offices of Purchaser's 
counsel in New York, New York (the "CLOSING"). Unless delayed by a Purchaser 
Blackout pursuant to Section 5.2(c), the Closing will occur on a date no 
later than the fifth Business Day following the date on which all the 
conditions contained in Sections 6.1 (a), (c) and (d) shall have been 
satisfied and Purchaser shall have been notified that the condition contained 
in Section 6.1(e) will be satisfied upon its written acceleration request 
(the "SCHEDULED CLOSING DATE"). The time when the Merger shall become 
effective is herein referred to as the "EFFECTIVE TIME", and the date on 
which the Effective Time occurs is herein referred to as the "CLOSING DATE."

                  1.3. EFFECT OF THE MERGER; CONVERSION OF SECURITIES. (a) At
the Effective Time, the effect of the Merger shall be as provided in the
Certificate of Merger and the applicable provisions of the DGCL. Without

and franchises of the Company and Merger Sub shall vest in the Surviving
Corporation and (ii) all debts, liabilities and duties of the Company and Merger
Sub (including, without limitation, the FCC Liability, as hereinafter defined)
shall become the debts, liabilities and duties of the Surviving Corporation.

                  (b) At the Effective Time, by virtue of the Merger and without
any action on the part of any holder of securities:

                           (i) each share of Company Preferred Stock shall be
                  converted in accordance with its terms into the right to
                  receive a portion of the Merger Consideration (defined below)
                  equal to its Preferred Liquidation Preference, PROVIDED that,
                  in the event of a Purchaser Share Election, subject to the
                  Stockholders' Election contemplated by Section 1.6, if the
                  amount of the aggregate Liquidation Preference exceeds the
                  aggregate cash portion of the Merger Consideration, such
                  excess shall be payable in shares of Purchaser Common Stock,
                  valued as provided below;

                           (ii) each share of Company Common Stock (other than
                  shares as to which appraisal rights shall have been perfected
                  under Section 262 of the DGCL ("Dissenting Shares")) shall be
                  converted into the right to receive (subject, in the event of
                  a Purchaser Share Election, to the Stockholders' Election
                  contemplated by Section 1.6) a pro rata portion of the 


                                      -3-
<PAGE>

                  Merger Consideration (other than the portion thereof 
                  attributed to the Preferred Stock, as provided in clause 
                  (i) above and other than the Escrowed Merger Consideration 
                  defined below), share for share, without any distinction 
                  between the two classes thereof; PROVIDED, HOWEVER, that 
                  (A) the Merger Consideration attributable to the Company 
                  Common Stock or Company Preferred Stock of any stockholder 
                  of the Company who does not execute and deliver the Consent 
                  and Indemnity Agreement of Stockholders and/or the Consent 
                  and Indemnity Agreement of Preferred Stockholders shall be 
                  placed into escrow (the "ESCROWED MERGER CONSIDERATION") 
                  pursuant to an Escrow Agreement in the form attached hereto 
                  as EXHIBIT D and (B) an amount in cash representing the 
                  amount of Merger Consideration into which the Dissenting 
                  Shares would have been converted had they not been 
                  Dissenting Shares shall be placed into the Dissenting 
                  Stockholder Escrow Account.

                           (iii) each share of Merger Sub Common Stock shall
                  thereafter remain outstanding as one validly issued, fully
                  paid and nonassessable share of common stock, $.0l par value,
                  of the Surviving Corporation;

                           (iv) each holder of a certificate representing any
                  shares of Company Common Stock or Company Preferred Stock
                  shall thereupon cease to have any rights with respect thereto,
                  except the right to receive Merger Consideration (whether upon
                  consummation of the Merger or upon release of the Escrowed
                  Merger Consideration); and

                           (v) the stock transfer books of the Company shall be
                  closed and there shall not be any further registration of
                  transfers of shares of any shares of capital stock thereafter
                  on the records of the Company.

                  1.4. CERTIFICATE OF INCORPORATION; BY-LAWS; DIRECTORS AND
OFFICERS. (a) Unless otherwise determined by Purchaser before the Effective
Time, at the Effective Time the Certificate of Incorporation of Merger Sub, as
in effect immediately prior to the Effective Time, shall be the Certificate of
Incorporation of the Surviving Corporation until thereafter amended as provided
by law and such Certificate of Incorporation.

                  (a)(b) The By-Laws of Merger Sub, as in effect immediately
prior to the Effective Time, shall be the By-Laws of the Surviving Corporation
until thereafter amended as provided by law, the Certificate of Incorporation of
the Surviving Corporation and such By-Laws.

                  (c) The directors of Merger Sub immediately prior to the
Effective Time will be the initial directors of the Surviving


                                      -4-
<PAGE>

Corporation, and the officers of Merger Sub immediately prior to the 
Effective Time will be the initial officers of the Surviving Corporation. If, 
at the Effective Time, a vacancy shall exist on the Board of Directors or in 
any office of the Surviving Corporation, such vacancy may thereafter be 
filled in any manner provided by law.

                  1.5. MERGER CONSIDERATION. (a) The merger consideration (the
"MERGER CONSIDERATION") will be equal to the excess of the sum of (w)
$695,000,000 and (x) any Positive Adjustments (as defined below) over the sum of
(y) the FCC Liability and (z) any Negative Adjustments (as defined below). The
cash portion of the Merger Consideration will be no less than $186,868,132
(inclusive of the amount of cash placed in the Dissenting Stockholders Escrow
Account pursuant to Section 5.5(b)), as adjusted by the net amount of the
Positive Adjustments and Negative Adjustments hereinafter defined. The Purchaser
may elect in its sole discretion, to pay all or any part of the remainder of the
Merger Consideration in shares of Purchaser Common Stock(a "PURCHASER SHARE
ELECTION") or in cash or, PROVIDED that Purchaser shall not make a Purchaser
Share Election unless (i) the value of shares of Purchaser Common Stock received
as Merger Consideration will constitute no less than 50% of the total value of
the Merger Consideration at the Effective Time and (ii) the Merger will
thereafter qualify for federal income tax purposes as a reorganization under the
provisions of Section 368(a)(2)(D) of the Code. For purposes of determining the
number of shares of Purchaser Common Stock to be issued in the Merger, each
share of Purchaser Common Stock will be deemed to have a value equal to its
Volume-Weighted Average Trading Price (as defined below) for the twenty trading
days preceding (but not including) (i) the Closing Date (the "CLOSING DATE
AVERAGE PRICE") or (ii) in the event of a Purchaser Blackout (as defined in
Section 5.2(c)), the Scheduled Closing Date (with appropriate adjustments for
any stock splits, stock dividends or the like that may occur during such
period). "Volume-Weighted Average Trading Price" means, for any period, (i) the
average of the daily prices for each trading day during such period, with each
daily price computed as the product of (x) the sale price times (y) the number
of Purchaser Shares sold at such price, divided by (ii) the total number of
Purchaser shares so traded during such trading day, all as reported by
Bloomberg, L.P.

                  (b) The "FCC LIABILITY" will be equal to the sum of (x)
$152,892,129 (representing the amount of the bidding credits claimed and
utilized by the Company in the LMDS Auction) plus (y) interest thereon owed to
the U.S. Government through and including the Closing Date or the date on which
the FCC Liability is paid, whichever is earlier, at the rate of interest
specified in the LMDS Rules.

                  (c)(i) The "POSITIVE ADJUSTMENTS" shall be the amount of cash,
accounts receivable and current assets shown on the


                                      -5-
<PAGE>

Final Closing Balance Sheet (as defined below) plus the amount of the 
Company's capital expenditures made through (but not including) the Closing 
Date to the extent contemplated by the Capital Expenditure Budget attached 
hereto as ANNEX A or otherwise approved in writing by Purchaser.

                  (ii) The "NEGATIVE ADJUSTMENTS" shall be the sum, without
duplication, of (w) the amount of total liabilities (other than the FCC
Liability) of the Company as of the Closing Date, whether matured, unmatured,
contingent or otherwise, with all contractual liabilities of the Company
determined as though all such contracts were terminated immediately prior to the
Closing, with all costs or expenses that would be incurred in connection with
any such termination were treated as liabilities of the Company as of the
Closing Date, PROVIDED that any unmatured or contingent liability shall be
valued net of the value of any current asset, not otherwise accounted for as a
Positive Adjustment, that would become an asset of the Company upon the
maturation of such liability or the occurrence of such contingency, as the case
may be, (x) the amount required to retire all of the Company's outstanding stock
options pursuant to Section 1.8, and (y) any Loss occurring prior to the Closing
to the extent indemnified pursuant to Article VIII.

                  (iii) Commencing promptly after the date hereof, and updated
at regular intervals thereafter (and on a daily basis during the week prior to
the anticipated Closing Date), the Company shall prepare and deliver to
Purchaser a detailed estimated balance sheet of the Company as of the Closing
Date immediately prior to the Effective Time prepared in accordance with
generally accepted accounting principles (the "INITIAL CLOSING BALANCE SHEET")
and including, in addition, as footnotes, any additional liabilities of the
Company as of the Closing Date determined in accordance with clause (ii)(w)
above. Upon Purchaser's request, the Company shall make available to Purchaser
and its accountants and other representatives the work papers and back-up
materials used in preparing the Initial Closing Balance Sheet and such other
documents as Purchaser may reasonably request in connection with its review of
the Initial Closing Balance Sheet. In the event Purchaser states any objections
to the Initial Closing Balance Sheet or asserts any Loss indemnified pursuant to
Article VIII, Purchaser and the Company shall cooperate fully with each other in
making such adjustments to the Initial Closing Balance Sheet as the parties may
agree, and the Initial Closing Balance Sheet, as so adjusted shall be the "FINAL
CLOSING BALANCE SHEET," which shall be determinative of all Positive Adjustments
and Negative Adjustments for purposes of proceeding with the Closing. Any
objections or Claims that remain unresolved on the Closing Date will be resolved
following the Closing in accordance with Section 8.5 as if the dispute were a
claim for reimbursement under Article VIII.


                                      -6-
<PAGE>

                  (d) At any time prior to the Closing, Purchaser will inform
the Company as to whether and to what extent it will make a Purchaser Share
Election. At the Closing (i) Purchaser will deliver to the Stockholders'
Representative or as the Stockholders' Representative shall direct an amount of
cash and/or shares of Purchaser Common Stock having a value equal to the Merger
Consideration and (ii) the Stockholders' Representative will deliver, on behalf
of the Company's stockholders, certificates, representing all outstanding shares
of Company Common Stock and Company Preferred Stock together with duly executed
letters of transmittal or affidavits of loss with full indemnification from a
financially responsible entity (to the extent such items have been received by
the Stockholders' Representative).

                  1.6. STOCKHOLDERS' ELECTION. The Company will use reasonable
efforts to ascertain the preferences, if any, of the holders of Company Common
Stock and Company Preferred Stock to receive Merger Consideration in the form of
cash or stock in the event Purchaser makes a Purchaser Share Election. On the
Closing Date, the Stockholder's Representative (with the consent of those
holders of Company Common Stock and Company Preferred Stock entitled to receive
a majority of the Merger Consideration) will allocate the cash and stock
portions of the Merger Consideration among the holders of Company Common Stock
and Company Preferred Stock, accommodating their expressed preferences to the
greatest practicable extent (and subject to the right of the holders of Company
Preferred Stock to receive cash to the maximum extent available), such
allocation to be without liability to the Stockholders' Representative and,
absent manifest error, conclusive.

                  1.7. ADDITIONAL ACTIONS. If, at any time after the Effective
Time, the Surviving Corporation shall consider or be advised that any deeds,
bills of sale, assignments, assurances or any other actions or things are
necessary or desirable to vest, perfect or confirm of record or otherwise in the
Surviving Corporation its right, title or interest in, to or under any of the
rights, properties or assets of Merger Sub or the Company or otherwise to carry
out this Agreement, the officers and directors of the Surviving Corporation
shall be authorized to execute and deliver, in the name and on behalf of Merger
Sub or the Company, all such deeds, bills of sale, assignments and assurances
and to take and do, in the name and on behalf of Merger Sub or the Company, all
such other actions and things as may be necessary or desirable to vest, perfect
or confirm any and all right, title and interest in, to and under such rights,
properties or assets in the Surviving Corporation or otherwise to carry out this
Agreement, provided that no such additional actions shall create or increase
recourse of any kind to former officers, directors or stockholders of the
Company, except as otherwise provided in this Agreement.


                                      -7-

                  1.8. OPTIONS; STOCK PLANS. Each option to acquire shares held
by an employee of the Company that is outstanding immediately prior to the
Merger, whether or not then vested or exercisable, shall, simultaneously with
the Merger, be canceled in exchange for a prompt payment of a single lump sum
cash payment equal to the product of (1) the number of Shares subject to such
Company Stock Option and (2) the excess, if any, of the Merger Consideration per
share over the exercise price per share of such Company Stock Option. The
Company will use its reasonable best efforts to obtain any agreement of
optionholders necessary to effectuate the foregoing, it being understood and
agreed that the cost to liquidate any such agreements with nonconsenting
optionholders will be accounted for as a Negative Adjustment.

                                   ARTICLE II.

                  REPRESENTATIONS AND WARRANTIES OF THE COMPANY

                  The Company represents and warrants to Purchaser and Merger
Sub as follows, subject in each case to the exceptions and qualifications set
forth on the Company Disclosure Schedule delivered herewith (the "Disclosure
Schedule"):

                  2.1. ORGANIZATION AND GOOD STANDING. The Company is a
corporation duly organized, validly existing and in good standing under the laws
of the State of Delaware and has all requisite corporate power and authority to
own, lease and operate its properties and to carry on its business as now being
conducted. The Company is duly qualified or licensed and in good standing to do
business in each jurisdiction in which the character of the property owned,
leased or operated by it or the nature of the business conducted by it makes
such qualification or licensing necessary except where the failure to be so
qualified or licensed would not be reasonably likely to have a Company Material
Adverse Effect. The Company has heretofore made available to Purchaser accurate
and complete copies of its Certificate of Incorporation and Bylaws, as currently
in effect. In this Agreement, any adverse effect on the business, assets,
condition (financial or other), results of operations or prospects of the
Company is referred to as a "COMPANY ADVERSE EFFECT", and a Company Adverse
Effect that is material to the business, assets, condition (financial or other),
results of operations or prospects of the Company and its subsidiaries (if any)
taken as a whole is referred to as a "Company Material Adverse Effect."

                  2.2. CAPITALIZATION. As of the date hereof, the authorized
capital stock of the Company consists of (i) 2,000 shares of Voting Common

<PAGE>

which 192,020.997 shares are issued and outstanding (collectively, the 
"SHARES"), and as of the Closing Date, the Company will have outstanding no 
shares of capital stock of any class other than the classes to which the 
Shares belong. As of the date hereof, no other capital stock of the Company 
is authorized or issued, including without limitation any treasury shares. 
All issued and outstanding Shares are duly authorized, validly issued, fully 
paid and non-assessable. As of the date hereof, except set forth in Section 
2.2 of the Disclosure Schedule, there are no outstanding rights, 
subscriptions, warrants, puts, calls, preemptive rights, options or other 
agreements of any similar kind relating to any of the outstanding, authorized 
but unissued, unauthorized or treasury shares of the Company or any other 
security of the Company, and there is no authorized or outstanding security 
of any kind convertible into or exchangeable for any such stock or other 
security.

                  2.3.  STOCKHOLDERS; NO SUBSIDIARIES; LIMITED BUSINESS.  (a) 
Section 2.3 of the Disclosure Schedule lists all of the issued and 
outstanding Shares of the Company's capital stock and the record ownership 
thereof as of the date hereof.  To the knowledge of the Company, except as 
set forth on such Schedule, no other Person has any right to or interest of 
record in any of such shares.

                  (a)(b) The Company has no Subsidiaries or ownership interests
of any kind in any Person (other than short-term investment vehicles).

                  (c) From the date of its formation through the date hereof,
the Company has engaged in no business other than bidding for and obtaining its
LMDS licenses, obtaining the requisite financing therefor, engaging in RF design
and evaluation of equipment (through equipment trials and otherwise), engaging
in strategic discussions regarding business relationships, marketing studies and
similar development stage activities and implementing its business plan for LMDS
and related telecommunications services.

                  2.4. AUTHORIZATION; BINDING AGREEMENT. The Company has all
requisite corporate power and authority to execute and deliver this Agreement
and to consummate the transactions contemplated hereby. The execution and
delivery of this Agreement and the consummation of the transactions contemplated
hereby, including, but not limited to, the Merger, have been duly and validly
authorized by the Board of Directors of the Company and have been approved and
adopted by the stockholders of the Company in accordance with the DGCL. No other
corporate proceedings on the part of the Company are necessary to authorize the
execution and delivery of this Agreement or the consummation of the transactions
contemplated hereby. This Agreement has been duly and validly executed and
delivered by the Company and


                                      -9-

constitutes the legal, valid and binding agreement of the Company, 
enforceable against the Company in accordance with its terms, except to the 
extent that enforceability thereof may be limited by applicable bankruptcy, 
insolvency, reorganization or other similar laws affecting the enforcement of 
creditors' rights generally and by principles of equity regarding the 
availability of remedies ("ENFORCEABILITY EXCEPTIONS").

                  2.5. GOVERNMENTAL APPROVALS. No consent, approval, waiver or
authorization of, or notice to or declaration or filing with ("CONSENT"), any
government, any political subdivision, any governmental or regulatory authority,
agency, department, board, commission, administration or instrumentality or any
court, tribunal, arbitrator or self-regulatory organization ("GOVERNMENTAL
AUTHORITY") on the part of the Company is required in connection with the
execution or delivery by the Company of this Agreement or the consummation by
the Company of the transactions contemplated hereby other than (i) the filing of
the Certificate of Merger with the Secretary of State of Delaware in accordance
with the DGCL, (ii) FCC approval of the LMDS license assignment application
contemplated hereby and (iii) expiration or early termination of the waiting
period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 (the
"H-S-R ACT").

                  2.6. NO VIOLATIONS; CONSENTS. The execution and delivery of
this Agreement, the consummation of the transactions contemplated hereby and
compliance by each of the Company and the stockholders of the Company with the
provisions hereof do not and will not (i) conflict with or result in any breach
of any provision of the Certificate of Incorporation or Bylaws of the Company,
(ii) require any consent, approval or action of, or notice to be given to, any
corporation, person or firm, or result in a violation or breach of, or
constitute (with or without notice or lapse of time or both) a default (or give
rise to any right of termination, cancellation or acceleration) under any of the
terms, conditions or provisions of any contract or agreement to which the
Company is a party, (iii) result in the creation or imposition of any lien or
encumbrance of any kind upon any of the assets of the Company or (iv) subject to
obtaining the Consents referred to in Section 2.5, contravene any applicable
provision of any statute, law, rule or regulation or any order, decision,
injunction, judgment, award or decree ("LAW") to which the Company or its assets
or properties are subject.

                  2.7. COMPANY FINANCIAL STATEMENTS. The unaudited financial
statements of the Company (the "COMPANY FINANCIAL STATEMENTS"), as of November
30, 1998 (the "BALANCE SHEET DATE") in the form attached hereto as ANNEX B, have
been prepared in good faith from, and are consistent with, the books and records
of the Company. The Company has not yet finalized its accounting principles, and
believes that certain adjustments to the Company Financial Statements will be
required to bring them into accord with generally accepted accounting
principles. Such adjustments


                                      -10-
<PAGE>

may include, without limitation, adjustments to reflect capitalization and 
depreciation policies, provisions for income taxes and normal recurring 
accrual adjustments, but such adjustments will not, in the aggregate, be 
material.

                  2.8. ABSENCE OF CERTAIN CHANGES OR EVENTS. Since the Balance

adverse effect on the business, assets, condition (financial or other),
prospects or results of operations of Purchaser and its subsidiaries taken as a
whole (a "PURCHASER MATERIAL ADVERSE EFFECT"). Purchaser has heretofore made
available to the Stockholders and the Company accurate and complete copies of

not (i) conflict with or result in any breach of any provision of the
Certificate or Articles of Incorporation or Bylaws or other governing
instruments of Purchaser or Merger Sub, (ii) require any Consent under or result
in a violation or breach of, or constitute (with or without notice or lapse of
time or both) a default (or give rise to any right of termination, cancellation
or acceleration) under any of the terms, conditions or provisions of any
Purchaser Material Contract (as hereinafter defined), (iii) result in the
creation or imposition of any lien or encumbrance of any kind upon any of the
assets of Purchaser or Merger Sub or (iv) subject to obtaining the Consents from
Governmental Authorities referred to in SECTION 3.4 hereof, contravene any Law
to which Purchaser or Merger Sub or its or any of their respective assets or
properties are subject, except, in the case of clauses (ii), (iii) and (iv)

likely to have a Purchaser Material Adverse Effect.

in the notes thereto) and present fairly, in all material respects, the
financial position of Purchaser and its subsidiaries as at the dates thereof and
the results of their operations and cash flows for the periods then ended

Governmental Authority in connection with the transactions contemplated by this
Agreement; or (iii) the commencement of any Litigation involving or affecting

subsidiaries which, if pending on the date hereof, would have been required

of the Merger. In addition, Purchaser shall give prompt written notice to the 
Company of the occurrence of any event which would be reasonably likely to 
have a Purchaser Material Adverse Effect and the Company shall give prompt 
written notice to Purchaser of the occurrence of any event which would be 
reasonably likely to have a Company Material Adverse Effect.

                  5.2. REASONABLE BEST EFFORTS; INTENDED TAX TREATMENT. Subject
to the terms and conditions herein provided, Purchaser and the Company agree to
use all reasonable best efforts to take, or cause to be taken, all actions and
to do, or cause to be done, all things necessary, proper or advisable to
consummate and make effective as promptly as practicable the transactions
contemplated by this Agreement, including, but not limited to:

                  (a) making all necessary applications and/or filings with the

and will use its respective reasonable best efforts to have the Registration
Statement cleared by the SEC staff as promptly as practicable after such filing
so that it may be made effective on the Scheduled Closing Date, PROVIDED,
HOWEVER, that the Purchaser shall have the right to delay the effectiveness of
the Registration Statement for up to 30 days following the Scheduled Closing
Date if such registration or sale, as applicable, would, in the judgment of the
Purchaser as reflected in an officer's certificate delivered to the Company,
require disclosures that would not be in the Purchaser's best interest to make
at such time (a "Purchaser Blackout"); and

                   (d) in the event of a Purchaser Share Election, causing the

                                      -20-
<PAGE>

necessary to satisfy the other conditions of the Closing set forth herein, 
PROVIDED that nothing contained in this Agreement shall be construed to 
require Purchaser to accept any term or condition or restriction required or 
imposed by any Government Authority in connection with the governmental 
approvals being sought for the transactions contemplated hereby (other than 
the FCC Liability), except for any terms, conditions or restrictions that are 
of an administrative or ministerial nature or otherwise fully compensated by 
the adjustment mechanisms contemplated by Sections 1.5 and 7.1(e). In 
addition, each of Purchaser and the Company will notify the other promptly 
upon the receipt of any comments from the SEC or its staff or any other 
government officials and of any request by the SEC or its staff or any other 
government officials for amendments or supplements to the Registration 
Statement or any other regulatory filing or for additional information and 
will promptly supply the other with copies of all correspondence between such 
party or any of its representatives, on the one hand, and the SEC, or its 
staff or any other government officials, on the other hand, with respect to 
the Registration Statement or any other regulatory filing. Purchaser will not 
take any action that would cause the last sentence of Section 3.4 to be 
untrue at any time prior to the Closing, unless such action would not (i) 
result in an adverse effect on Purchaser's qualifications to be a holder of 
the LMDS Licenses or (ii) otherwise adversely affect the consummation of the 
transactions contemplated hereby. Without limitation, Purchaser will promptly 
notify the Company upon its receipt of Purchaser any notification from the 
SEC that the condition contained in Section 6.1(e) will be satisfied upon its 
written acceleration request.

                  5.3. PUBLIC ANNOUNCEMENTS. So long as this Agreement is in
effect, the Company shall not issue or cause the publication of any press
release or of any other announcement with respect to the Merger or the

are, as of the date of this Agreement, "affiliates" of the Company for purposes

stockholders pursuant to Section 262(d)(2) of the DGCL, and shall thereafter

Purchaser agrees to create an escrow account on terms reasonably satisfactory to
the Company to be funded on the Closing Date with the value of the Merger

Dissenting Stockholders under Section 262 of the DGCL, all amounts remaining in
the Dissenting Stockholders Escrow Account shall be released to the
Stockholders' Representative for distribution to former holders of Company
Common Stock.

after the date hereof and on or prior to the Closing Date (or, in the event of a
Purchaser Blackout, on or prior to the Scheduled Closing Date) any event that
would be reasonably likely to have a Company Material Adverse Effect, PROVIDED
that in the event that the Company shall have given a notice as contemplated by

have occurred, Purchaser shall not be entitled to rely on any fact which both

the date of such notice.

                  (b) PERFORMANCE BY THE COMPANY. The Company shall have
performed and complied with all the covenants and agreements in all material

shall not be deemed breached as a result of any fact which both (i) was
described in detail in such notice and (ii) had already occurred as of the date
of such notice) except to the extent that any such representation and warranty
had by its terms been made as of the date hereof or another specific date, in
which case such representation and warranty shall have been true and correct as
of the date hereof or such specific date, as the case may be), except, in all
instances, where the failure to be so true and correct shall not result,
individually or in the aggregate, in a Company Material Adverse Effect; and
Purchaser shall have received a certificate signed on behalf of the Company by

                  (e) NO CONDITIONS. No Governmental Authority having

                                   TERMINATION

     (a) by the mutual written consent of Purchaser and the Company, by action
of their respective Boards of Directors; or

Date (or within 30 days thereafter, in the event of a Purchaser Blackout) any
condition to the Merger has not been satisfied or waived by the party or parties
entitled to the benefit of the same; PROVIDED, HOWEVER, that the right to
terminate this Agreement pursuant to this Section 7.1(b) shall not be available
to any party whose failure to perform any of its obligations under this
Agreement results in the failure of any such other condition to be satisfied; or

                  (c) by Purchaser or the Company if the Closing shall not have
occurred on or before January 14, 2000; PROVIDED, HOWEVER, that the right to
terminate this Agreement pursuant to this Section 7.1(c) shall not be available

Agreement results in the failure of the Closing to occur by such date; or

                  (d) by Purchaser or the Company if any court of competent
jurisdiction or other Governmental Authority has issued an order, decree or
ruling or taken any other action restraining, enjoining or otherwise prohibiting
the Merger and such order, decree, ruling or other action shall have become
final and nonappealable; or

                  (e) by Purchaser or the Company if the FCC shall have imposed
any payment in excess of the FCC Liability in connection with the transactions
contemplated hereby, unless the party to this Agreement not seeking termination
pursuant to this Section 7.1(e) agrees in writing to bear such excess expense,
in which


                                      -26-
<PAGE>

event the adjustment provisions of Section 1.5 shall be construed to so

                  (f) by either Purchaser or the Company upon written notice to
the other if the terminating party is not in material breach of its obligations
under this Agreement and if the other party or its subsidiary shall have
materially breached this Agreement and such breach shall not have been cured in
all material respects or waived prior to the earlier to occur of the Closing
Date or thirty (30) days following the date the terminating party shall have
given the other party written notice of such breach setting forth the nature
thereof in reasonable detail; or

                  (g) by Purchaser, within 20 days of its receipt of written
notice from the Company acknowledging the occurrence of an event that would be
reasonably likely to have a Company Material Adverse Effect and describing in
detail the facts giving rise to such occurrence.

                  7.2. EFFECT OF TERMINATION.  In the event of the 
termination of this Agreement pursuant to Section 7.1, this Agreement shall 
forthwith become void and have no effect, without any liability on the part 
of any party or its directors, officers or stockholders, except for the

                        INDEMNIFICATION AND REIMBURSEMENT

                  8.1. INDEMNIFICATION BY STOCKHOLDERS. (a) In order to induce
Purchaser to enter into this Agreement and to consummate the transactions
contemplated hereby, each holder of Company Common Stock and/or Company
Preferred Stock, by virtue of its execution of the Consent and Indemnity
Agreement of Stockholders and/or the Consent and Indemnity Agreement of
Preferred 


                                      -27-
<PAGE>

Stockholders (an "INDEMNIFYING PARTY"), agrees, subject to the further 
provisions of this Article VIII, severally to indemnify Purchaser and, 
without duplication, its stockholders, directors, officers and employees 
(collectively, the "INDEMNIFIED PARTIES") and shall hold the Indemnified 
Parties harmless against and with respect to any "Loss" which for purposes of 
this Agreement shall include any and all actual liabilities, costs, losses, 
damages and expenses (whether or not arising out of third party claims), 
including without limitation reasonable attorneys' fees (after giving effect 
to any offsetting benefit actually received or receivable), incurred by the 
Indemnified Parties and arising out of or resulting from:

                  (i)  any misrepresentation or breach of warranty by the 
        Company of any of its representations or warranties set forth in this 
        Agreement or any Annex, Schedule or Exhibit hereto;

                  (ii) any breach or nonfulfillment by the Company of any of 
        its covenants, agreements or other obligations set forth in this 
        Agreement or any Annex, Schedule or Exhibit hereto; and

                  (iii) any amounts owed to Dissenting Stockholders in excess of
        the amount of cash held in the Dissenting Stockholders Escrow Account.

                  (b) Entitlement to indemnification pursuant to this Section 
8.1 shall be conditioned upon claims in respect thereof being submitted in 
writing with detailed specification showing the basis of such claim, 
including the provision of this Agreement breached, and a reasonably detailed 
calculation of the amount of such claim, if at all, by Purchaser to the 
Indemnifying Parties no later than twelve (12) months after the Effective 
Time.

                  (c) Notwithstanding anything to the contrary in this 
Section 8.1, the right to indemnity in respect of matters provided for in 
paragraphs (a)(i) and (ii) of this Section 8.1 shall not be barred on the 
basis that the amount of the claim has not been ascertained, liquidated or 
reduced to final judgment on or before the expiration of the aforesaid 
period, provided that such claim is identified in writing with detailed 
specification showing the basis of such claim, including the provision of 
this Agreement breached, and a reasonable estimate of the amount of such 
claim.

                  (d) Notwithstanding anything in this Agreement to the
contrary, with respect to any amounts payable under this Agreement, (i) no
Indemnifying Party shall be liable for more than its Pro Rata Share of any Loss
and (ii) the maximum amount of liability of any Indemnifying Party shall in no
event exceed the amount of the Merger Consideration received by such
Indemnifying Party. For purposes of this Agreement, "PRO RATA


                                      -28-
<PAGE>

SHARE" shall mean a fraction the numerator of which is the amount of the 
Merger Consideration received by such Indemnifying Party and the denominator 
of which is the aggregate Merger Consideration. The remedies provided in this 
Article VIII and in Section 9.12 shall be Purchaser's sole remedies hereunder 
for breach of this Agreement, except in the case of fraud.

                  8.2. CLAIMS FOR REIMBURSEMENT. In the event that any
Indemnified Party suffers any Loss (as hereinabove defined) with respect to any
liability or claim to which the foregoing indemnities relate, such Person shall
give the Indemnifying Parties prompt written notice of the nature and amount of
such Loss and the Indemnified Party's claim for reimbursement therefor and if
such Loss is with respect to a third party claim, accompanied by a copy of the
written notice from the third party claimant. The Indemnifying Parties shall
have 30 days from the date of said notice to investigate and dispute the nature,
validity or amount of any such claim. During said 30-day period, representatives
of one law firm and one accounting firm designated by a majority in interest (as
measured by aggregate potential liability) of the Indemnifying Parties shall
have reasonable access, during normal business hours, to the books and records
of the Indemnified Party for the purpose of such investigation. In the event
that any Indemnifying Party disputes the nature, validity or amount of said
claim, such Indemnifying Party shall give the Indemnified Party written notice
of such dispute within said 30-day period, and the parties shall attempt in good
faith to resolve such dispute. If such dispute is not resolved within 10 days
following receipt of said notice of dispute by the Indemnified Party, the
provisions of Section 8.5 hereof shall apply to such dispute.

                  In the absence of a dispute, each Indemnifying Party shall
promptly (but not later than the expiration of said 30-day period) reimburse the
Indemnified Party for its Pro Rata Share of any such Loss. In the event that the
Stockholders' Representative disputes only the amount of the claim, each
Indemnifying Party shall, concurrently with the delivery of the Stockholders'
Representative's notice of dispute, pay to the Indemnified Party its Pro Rata
Share of the undisputed portion of such claim and the provisions of Section 8.5
hereof shall apply to the disputed portion of such claim.

                  All payments by an Indemnifying Party hereunder shall be in
cash to the extent of the cash received (on an after-tax basis) by such
Indemnifying Party as Merger Consideration or upon sale of shares of Purchaser
Common Stock received as Merger Consideration. Any additional payments required
of an Indemnifying Party may be paid in cash, if the Indemnifying Party so
elects, and may, under the circumstances described below, be paid in shares of
Purchaser Common Stock. Any Indemnifying Party wishing to satisfy an
acknowledged liability hereunder in shares of Purchaser Common Stock shall so
notify Purchaser at the time


                                      -29-
<PAGE>

such payment is due, such notice to be accompanied by such Indemnifying 
Party's agreement to permit Purchaser to elect whether to accept such payment 
directly (with the shares valued at their Volume-Weighted Average Trading 
Price for the twenty trading day period ending on the date prior to the 
delivery of such shares to Purchaser) or to arrange for an underwritten 
offering of such shares and other shares of Purchaser Common Stock, in which 
case the shares will be valued at the net proceeds received therefor in such 
offering. The terms of the Registration Rights Agreement applicable to 
incidental registrations will apply, mutatis mutandis, to any such offering.

                  8.3. REIMBURSEMENT FROM ESCROWED MERGER CONSIDERATION. In the
event that one or more holders of Company Common Stock and/or Company Preferred
Stock does not become an Indemnifying Party, and there is, therefore, Escrowed
Merger Consideration, then in the event that the Indemnifying Parties are
required to make an indemnification payment pursuant to Section 8.2, the Escrow
Agent shall promptly release Escrowed Merger Consideration to the Indemnified
Party in an amount equal to the product of (a) any such Loss (or undisputed
portion thereof) multiplied by (b) a fraction the numerator of which is the
amount of the Escrowed Merger Consideration and the denominator of which is the
aggregate Merger Consideration (an "ESCROW LOSS Reimbursement"). Escrow Loss
Reimbursements shall be made only in cash, provided that in the event that the
cash portion of the Escrowed Merger Consideration is less than the amount of the
Escrow Loss Reimbursement, the Escrow Agent shall sell, to the extent permitted
by applicable law, an amount of Purchaser Common Stock in brokers transactions
on the Nasdaq National Market equal in value to such cash deficiency. In the
event that the Escrow Agent is not permitted by applicable to sell shares of
Purchaser Common Stock, such cash deficiency shall be satisfied with shares of
Purchaser Common Stock valued at their Volume-Weighted Average Trading Price for
the twenty trading day period prior to the date on which the Indemnifying
Parties are required to make an indemnification payment pursuant to Section 8.2.

                  8.4. DEFENSE OF THIRD-PARTY CLAIMS. If any lawsuit or
enforcement action is filed, or claim asserted against an Indemnified Party by a
third party and the Indemnified Party is entitled to indemnification pursuant to
this Agreement, written notice thereof shall be given to the Indemnifying Party
as promptly as practicable (and in any event no later than 30 days after the
service of the citation or summons or receipt of other written notice of such
claim); the failure of any Indemnified Party to give timely notice shall limit
the rights to indemnification hereunder only if and to the extent that (i) such
failure to give timely notice materially affects the ability or right of the
Indemnifying Party to participate in the defense of such lawsuit or enforcement
action or claim, (ii) actual notice is not given to the Indemnifying Party
within a reasonable time, or (iii) to the extent that such failure to give
timely notice


                                      -30-
<PAGE>

causes the Indemnifying Party to incur additional expense with respect to 
such lawsuit or enforcement action, the Indemnified Party fails to promptly 
reimburse the Indemnifying Party for such additional expense.

                  The Indemnifying Party shall be entitled, if it so elects, to
take control of the defense and investigation of such lawsuit, action or claim,
and to employ and engage attorneys of its own choice to handle and defend the
same, at the Indemnifying Party's cost, risk and expense; and such Indemnified
Party shall cooperate in all reasonable respects, at its cost, risk and expense,
with the Indemnifying Party and such attorneys in the investigation, trial and
defense of such lawsuit or action and any appeal arising therefrom; PROVIDED,
HOWEVER, that the Indemnified Party may, at its own cost, participate in (but
not control) such investigation, trial and defense of such lawsuit or action and
any appeal arising therefrom.

                  If the Indemnifying Party does not elect to take control of
the defense and investigation of said lawsuit or action, then the Indemnified
Party shall remain in control thereof in such manner as it deems appropriate.

                  Neither party shall enter into any settlement, adjustment or
compromise of any lawsuit or action without the prior written consent of the
other party which consent will not be unreasonably withheld.

                  8.5. RESOLUTION OF DISPUTES. (a) In the event of any dispute
between Purchaser and the Indemnifying Parties over any claim for reimbursement
with respect to any matter to which the foregoing indemnities relate, such
dispute will be finally determined by the Accounting Firm (as defined below) in
the manner set forth in Section 8.5(b), and any Loss so determined will be
promptly reimbursed to Purchaser by the Indemnifying Parties.

                  (b) Any dispute pursuant to Section 8.5(a) will be resolved
by a member of the Washington, D.C. office of PricewaterhouseCoopers LLP (the
"ACCOUNTING FIRM"). The Accounting Firm shall be instructed to use all
reasonable efforts to resolve such disputes within thirty (30) days. The
resolution of disputes by the Accounting Firm so selected will be set forth in
writing and will be conclusive and binding upon all parties to such dispute and
the amount of the reimbursement payable as so resolved will become final and
binding upon the date of such resolution. The fees and expenses of the
Accounting Firm shall be paid by the unsuccessful party, if all the disputes are
resolved against such party, and in other cases shall be pro rated among the
parties as the Accounting Firm sees fit based on the relative success of the
parties in indicating their respective positions.

                  8.6. INDEMNIFYING PARTIES' DECISIONS Any decision with respect
to any matter under this Article VIII (including, without limitation, the
settlement, resolution or defense of claims) shall be binding upon all

                                  MISCELLANEOUS

                  9.1. CONFIDENTIALITY. In the event the transactions 
contemplated by this Agreement are not consummated, each party shall return 
to the other any documents furnished by the other and all copies thereof any 
of them may have made and will hold in absolute confidence any information 
obtained from the other party except to the extent (i) such party is required 
to disclose such information by Law or such disclosure is necessary or 
desirable in connection with the pursuit or defense of a claim, (ii) such 
information was known by such party prior to such disclosure or was 
thereafter developed or obtained by such party independent of such disclosure 
or (iii) such information becomes generally available to the public other 
than by breach of this SECTION 9.1.

                  9.2. AMENDMENT AND MODIFICATION. This Agreement may be 
amended, modified or supplemented only by a written agreement among each of 
the parties hereto or, following the Closing, by agreement of Purchaser and a 
Majority of Indemnifying Parties.

                  9.3. WAIVER; CONSENTS. Any failure of the Stockholders or the
Company on the one hand, or Purchaser or the Merger Sub on the other hand, to
comply with any obligation, covenant, agreement or condition herein may be
waived by Purchaser, on the one hand, or the Company (or, following the Closing,
by a Majority of Indemnifying Parties), on the other hand, only by a written
instrument signed by the party granting such waiver, but such waiver or failure
to insist upon strict compliance with such obligation, covenant, agreement or
condition shall not operate as a waiver of, or estoppel with respect to, any
subsequent or other failure. Whenever this Agreement requires or permits consent
by or on behalf of any party hereto, such consent shall be given in writing in a
manner consistent with the requirements for a waiver of compliance as set forth
in this SECTION 9.3. The Closing shall not be deemed to be a waiver of any claim
in respect of any Loss, known or unknown, occurring prior to the Closing Date,
resulting from breach, whether material or not, of any representation, warranty
of covenant contained in this Agreement.

                  9.11. ENTIRE AGREEMENT. This Agreement and the documents or
instruments referred to herein including, but not limited to, the Annex(es),
Schedules and Exhibits attached hereto, which Annex(es) are incorporated herein
by reference, embody the entire agreement and understanding of the parties
hereto in respect of the subject matter contained herein, provided that the
forms of agreements attached hereto as Exhibits shall be superseded by the
agreements executed and delivered by the respective parties thereto, the
execution and delivery of such documents by the parties thereto to be conclusive
evidence of such parties' approval of any change or modification therein. There
are no restrictions, promises, representations, warranties, covenants, or
undertakings, other than those expressly set forth or referred to herein. This
Agreement supersedes all prior agreements and the understandings between the
parties with respect to such subject matter.

                  9.12. SPECIFIC PERFORMANCE. The parties hereto agree that
irreparable damage would occur in the event that any of the provisions of this
Agreement were not performed in accordance with their specific terms or were
otherwise breached. Accordingly, the parties further agree that each party shall
be entitled to an injunction or restraining order to prevent breaches of this
Agreement and to enforce specifically the terms and provisions hereof in any
court of the United States or any state having jurisdiction, this being in
addition to any other right or remedy to which such party may be entitled under
this Agreement, at law or in equity.

                  9.13. THIRD PARTIES. Nothing contained in this Agreement or in
any instrument or document executed by any party in connection with the
transactions contemplated hereby shall create any rights in, or be deemed to
have been executed for the benefit of, any person that is not a party hereto or
thereto or a successor or permitted assign of such a party, except to the extent
that the Stockholders become third party beneficiaries hereof through their
execution and delivery of the ancillary agreements contemplated hereby.

                  9.14. STOCKHOLDERS' REPRESENTATIVE. (a) Following the 
Closing, the Stockholders' Representative shall have the right of reasonable 
access to the Company's and Merger Sub's books and records to the extent 
reasonably requested for purposes of tax matters, claims and any other proper 
purpose.

                  (b) The Stockholders' Representative agrees to act as such in
accordance with the terms and provisions of this Agreement, but may resign from
such duties at any time by written notice to the Company and each of the
Stockholders. A Majority of Indemnifying Parties (as such term is defined in
Section 8.6) may relieve the Stockholders' Representative of such duties at any
time by written notice to the Stockholders' Representative and the Company. Any
successor Stockholders' Representative


                                      -35-
<PAGE>

shall execute and deliver an instrument accepting such appointment and he 
shall, without further acts, be vested with all the rights, powers and duties 
of the predecessor Stockholders' Representative as if originally named as 
Stockholders' Representative. The Stockholders' Representative will have no 
liability for any action taken in good faith or with the consent of a 
Majority of Indemnifying Parties. The Stockholders' Representative may 
consult with, and obtain advice from, legal counsel in the event of any 
question as to any of the provisions hereof or the duties hereunder, and he 
shall incur no liability and shall be fully protected in acting in good faith 
in accordance with the opinion and instructions of such counsel. Each of the 
Stockholders, by virtue of its execution and delivery of the Consent and 
Indemnity Agreement of Stockholders, or the Consent and Indemnity Agreement 
of Preferred Stockholders, as the case may be, will be deemed to have agreed, 
severally and not jointly, to indemnify and hold the Stockholders' 
Representative harmless from and against such Stockholder's Pro Rata Share of 
any Loss incurred in connection with his duties as such, except with respect 
to actions not taken in good faith. Purchaser and the Company agree that the 
Stockholders' Representative does not assume any responsibility for the 
failure of any other party to perform in accordance with the Merger Agreement 
or this Agreement. The acceptance by the Stockholders' Representative of his 
responsibilities hereunder is subject to the following terms and conditions, 
which the other parties hereto agree shall govern and control with respect to 
the Stockholders' Representative's rights, duties, liabilities and immunities:

                  The Stockholders' Representative may conclusively rely, and
shall be protected in acting or refraining from acting upon, any written notice,
certification, request, waiver, consent, receipt or other paper or document
furnished to him not only as to its due execution and validity and effectiveness
of its provisions but also as to the truth and accuracy of any information
therein contained which the Stockholders' Representative reasonably believes to
be genuine and to have been signed and presented by the proper party or parties.
Should it be necessary for the Stockholders' Representative to act upon any
instructions, directions, documents or instruments issued or signed by or on
behalf of any corporation, fiduciary, or individual acting on behalf of another
party hereto, it shall not be necessary for the Stockholders' Representative to
inquire into such corporation's, fiduciary's or individual's authority,
capacity, existence or identity. The Stockholders' Representative is also
relieved from the necessity of satisfying himself as to the authority of the
persons executing this Agreement in a representative capacity.

                  The Stockholders' Representative shall have no duties except
those which are expressly set forth in this Agreement and in the Registration
Rights Agreement.

<PAGE>

                  Upon termination of all indemnification obligations under this
Agreement and all registration obligations under the Registration Rights
Agreement, the Stockholders' Representative shall thereafter be discharged from
any further obligations hereunder. The Stockholders' Representative is hereby
authorized, in any and all events, to comply with and obey any and all final
judgments, orders and decrees (not subject to appeal) of any court of competent
jurisdiction which may be filed, entered or issued, and, if it shall so comply
or obey, it shall not be liable to any other person by reason of such compliance
or obedience.

                  The Stockholders' Representative shall not have any
responsibility or liability for the completeness, correctness or accuracy of any
transactions between Purchaser, on the one hand, and the Company or its
stockholders, on the other hand.

                  In the event that the Stockholders' Representative shall be
uncertain as to his duties or rights hereunder or shall receive instructions
with respect to such duties which, in his sole opinion, are in conflict with
either other instructions received by him or any provision of this Agreement, he
shall without liability of any kind, be entitled to take no action pending the
resolution of such uncertainty to the Stockholders' Representative's sole
satisfaction, by final judgment of a court or courts of competent jurisdiction
or otherwise.

economic position enjoyed by each party as close as possible to that under 
the provision rendered unenforceable. In the event that the parties cannot 
reach a mutually agreeable and enforceable replacement for such provision, 
then (i) such provision shall be excluded from this Agreement, (ii) the 
balance of this Agreement shall be interpreted as if such provision were so 
excluded and (iii) the balance of this Agreement shall be enforceable in 
accordance with its terms.

                  5.10.  ATTORNEYS' FEES. Should suit be brought to enforce or
interpret any part of this Agreement, the prevailing party will be entitled to
recover, as an element of the costs of suit and not as damages, reasonable
attorneys' fees to be fixed by the court (including without limitation, costs,
expenses and fees on any appeal). The prevailing party will be entitled to
recover its costs of suit proceeds to final judgment.

                  5.11. SPECIFIC PERFORMANCE; INJUNCTIVE RELIEF. The parties
hereto acknowledge and agree that NEXTLINK will be irreparably harmed and that
there will be no adequate remedy at law for a violation of any of the covenants
or agreements of Holder set forth herein. Therefore, the parties acknowledge and
agree that, in addition to any other remedies that may be available to NEXTLINK
upon any such violation, NEXTLINK shall have the right to enforce such covenants
and agreements by specific performance, injunctive relief or by any other means
available to NEXTLINK at law or in equity.

                  NOW, THEREFORE, in consideration of the mutual covenants
contained herein and other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties to this Agreement
hereby agree as follows:

         1.       APPOINTMENT OF ESCROW AGENT; ESCROW DEPOSIT.

escrow agent under this Agreement, and the Escrow Agent accepts such appointment
according to the terms and conditions set forth herein. On the Closing Date,
Purchaser will deposit with the Escrow Agent pursuant to Section 1.3(b) of the

manage, administer, distribute and dispose of the Cash Escrow Deposit in
accordance with the terms and conditions of this Agreement. The Escrow Agent
shall not transfer, sell, pledge or otherwise dispose of or encumber the Stock

         2. INVESTMENT OF CASH ESCROW DEPOSIT. Until the termination of this
Agreement, the Cash Escrow Deposit, together with any interest earned thereon,
shall be invested (as directed in written instructions to the Escrow Agent from
time to time by Purchaser) solely in one or more of the investments referred to
below:

                  (a)  interest bearing time deposits with maturity dates of
30 days or less of any bank located within the United States of America;
PROVIDED that any amount held on deposit in any bank not having unsecured,
non-subordinated indebtedness outstanding that is rated as "investment grade" by
a nationally recognized rating agency shall be so invested only if such amount
is fully insured by the Federal Deposit Insurance Corporation ("FDIC");

                  (b)  certificates of deposit with maturity dates of 30
days or less issued by the commercial banking department of any bank located in
the United States of America, PROVIDED, HOWEVER,


                                     -2-
<PAGE>

that either (A) any such bank shall have unsecured, non-subordinated 
indebtedness outstanding that is rated as "investment grade" by a nationally 
recognized rating agency, or (B) the full amount of each and every 
certificate of deposit issued by any such bank to the Escrow Agent hereunder 
shall be fully insured by the FDIC;

                  (c)  direct obligations of, or obligations guaranteed as
to all principal and interest by, the United States of America, in each case
with maturity dates of 30 days or less;

                  (d)  repurchase agreements with maturity dates of 30 days

In the absence of any written instructions from Purchaser to the contrary, the
Escrow Agent is hereby authorized and directed to invest and reinvest the Cash
Escrow Deposit in interest bearing time deposits.

         The parties acknowledge that the Escrow Agent shall not be responsible
for any diminution in the Cash Escrow Deposit due to losses resulting from
investments made pursuant to this Agreement. The parties further acknowledge
that the Nonconsenting Holders shall not suffer any loss resulting from
investments made pursuant to this Agreement.

         3.       PAYMENTS FROM ESCROW; TERMINATION.  The Escrow Agent shall 
hold the Escrow Deposit in escrow in accordance with this Agreement and shall 
make payments from the Escrow Deposit only as follows:

                  (a)  In the event that the Indemnifying Parties are
required to make any payments in respect of any Loss pursuant to Section 8.2 of
the Merger Agreement, the Escrow Agent shall promptly release Escrowed Merger
Consideration to the Indemnified Party in an amount equal to the product of (a)
any such Loss (or undisputed portion thereof) multiplied by (b) a fraction, the
numerator of which is the amount of the Escrowed Merger Consideration, and the
denominator of which is the aggregate Merger Consideration (an "ESCROW LOSS
REIMBURSEMENT"). Escrow Loss Reimbursements shall be made only in cash, PROVIDED
that in the event that the cash portion of the Escrow Deposit is less than the
amount of the Escrow Loss Reimbursement, the Escrow Agent shall sell, to the
extent permitted by law, an amount of

<PAGE>

Purchaser Common Stock in brokers transactions on the Nasdaq National Market 
equal in value to such cash deficiency. In the event the Escrow Agent is not 
permitted by applicable law to sell shares of Purchaser Common Stock, such 
cash deficiency shall be satisfied with shares of Purchaser Common Stock 
valued at their Volume-Weighted Average Trading Price for the twenty trading 
day period prior to the date on which the Indemnifying Parties are required 
to make an indemnification payment pursuant to Section 8.2 of the Merger 
Agreement.

                  (b)  (i) In the event any Nonconsenting Holder executes
either the Consent and Indemnity Agreement of Stockholders or the Consent and
Indemnity Agreement of Preferred Stockholders, as the case may be, and delivers
a copy thereof to the Escrow Agent and Purchaser and at such time there is no
disputed or unsatisfied Loss, Purchaser shall instruct the Escrow Agent to
release to such Nonconsenting Holder its Pro Rata Share (as set forth opposite
the name of such Nonconsenting Holder on Schedule I or Schedule II hereto) of
the Escrow Deposit, less the amount of any payments from the Escrow Deposit
theretofore made on such holder's behalf pursuant to this Agreement.

                    (ii) In the event any Nonconsenting Holder executes
either the Consent and Indemnity Agreement of Stockholders or the Consent and
Indemnity Agreement of Preferred Stockholders, as the case may be, and delivers
a copy thereof to the Escrow Agent and Purchaser and at such time there is a
disputed or unsatisfied Loss, Purchaser shall instruct the Escrow Agent to
release to such Nonconsenting Holder its Pro Rata Share (as set forth opposite
the name of such Nonconsenting Holder on Schedule I or Schedule II hereto) of
the Escrow Deposit, less (A) the amount of any payments from the Escrow Deposit
theretofore made on such holder's behalf pursuant to this Agreement and (B) its
Pro Rata share of the disputed or unsatisfied portion of such Loss.

                    (iii) Should any Nonconsenting Holder execute and
deliver to Purchaser either the Consent and Indemnity Agreement of Stockholders
or the Consent and Indemnity Agreement of Preferred Stockholders, as the case
may be, at a time when there is no disputed or unsatisfied Loss, it shall cease
to be a Nonconsenting Holder.

                  (c)  If the Escrow Deposit shall not be fully drawn
pursuant to subsection (a) and (b) of this Section 3 by the later of (i) the
first anniversary of the Closing and (ii) the date on which any and all disputes
with respect to claimed Losses that are pending on that date have been resolved
and satisfied, the Escrow Agent shall release to each Nonconsenting Holder its
Pro Rata Share of the Cash Escrow Deposit and the Stock Escrow Deposit, PROVIDED
that amounts in the Cash Escrow Deposit shall be used FIRST to pay each
Nonconsenting Preferred Stockholder all of its Pro Rata Share of the Escrow
Deposit in cash, and SECOND,


                                     -4-
<PAGE>

to the extent any amounts remain in such Cash Escrow Deposit, to 
Nonconsenting Common Stockholders.

         4. CONDITIONS TO ESCROW. The Escrow Agent agrees to hold the Escrow
Deposit and to perform in accordance with the terms and provisions of this
Agreement. Purchaser agrees that the Escrow Agent does not assume any
responsibility for the failure of Purchaser to perform in accordance with the
Merger Agreement or this Agreement. The acceptance by the Escrow Agent of its
responsibilities hereunder is subject to the following terms and conditions,
which the parties hereto agree shall govern and control with respect to the
Escrow Agent's rights, duties, liabilities and immunities:

                  (a)  The Escrow Agent may conclusively rely, and shall be
protected in acting or refraining from acting upon, any written notice,
certification, request, waiver, consent, receipt or other paper or document
furnished to it, not only as to its due execution and validity and effectiveness
of its provisions but also as to the truth and accuracy of any information
therein contained which the Escrow Agent reasonably believes to be genuine and
to have been signed and presented by the proper party or parties. Should it be
necessary for the Escrow Agent to act upon any instructions, directions,
documents or instruments issued or signed by or on behalf of any corporation,
fiduciary, or individual acting on behalf of another party hereto, it shall not
be necessary for the Escrow Agent to inquire into such corporation's,
fiduciary's or individual's authority, capacity, existence or identity. The
Escrow Agent is also relieved from the necessity of satisfying itself as to the
authority of the persons executing this Agreement in a representative capacity.

                  (b)  The Escrow Agent may consult with, and obtain advice
from, legal counsel in the event of any question as to any of the provisions
hereof or the duties hereunder, and it shall incur no liability and shall be
fully protected in acting in good faith in accordance with the opinion and
instructions of such counsel.

                  (c)  The Escrow Agent shall have no duties except those
which are expressly set forth herein and it shall not be bound by (i) the Merger
Agreement or any agreement of the other parties hereto (whether or not it has
any knowledge thereof) or by any notice of a claim, or demand with respect
thereto, or (ii) any waiver, modification, amendment, termination or rescission
of this Agreement unless the Escrow Agent agrees thereto in writing.

                  (d)  The Escrow Agent may resign and be discharged from
its duties and obligations hereunder by giving notice in writing of such
resignation specifying a date (no earlier than 30 days following the date of
such notice) when such resignation will take effect, PROVIDED, HOWEVER, that
until a successor escrow agent is appointed by Purchaser, the Escrow Agent shall
continue to hold the Escrow Deposit and otherwise comply with the terms of


                                     -5-
<PAGE>

this Agreement; PROVIDED further that if no such successor escrow agent shall 
be appointed within 30 days of the Escrow Agent providing its notice, the 
Escrow Agent may, at the expense of Purchaser, (i) appoint a successor escrow 
agent which shall be a national or state-chartered banking, trust or savings 
association, (ii) petition any court of competent jurisdiction for the 
appointment of a successor escrow agent or (iii) may deposit the Escrow 
Deposit with the Clerk of the United States District Court for the Southern 
District of New York, or with the office of the clerk of registry of any 
other court of competent jurisdiction, at which time the Escrow Agent's 
duties hereunder shall terminate. Any successor escrow agent shall execute 
and deliver an instrument accepting such appointment and it shall, without 
further acts, be vested with all the estates, properties, rights, powers and 
duties of the predecessor escrow agent as if originally named as escrow 
agent. The resigning Escrow Agent shall thereupon be discharged from any 
further obligations under this Escrow Agreement.

                  (e)  Upon delivery of all of the entire Escrow Deposit
then remaining pursuant to the terms of Section 3 above or to a successor escrow
agent, the Escrow Agent shall thereafter be discharged from any further
obligations hereunder. The Escrow Agent is hereby authorized, in any and all
events, to comply with and obey any and all final judgments, orders and decrees
(not subject to appeal) of any court of competent jurisdiction which may be
filed, entered or issued, and, if it shall so comply or obey, it shall not be
liable to any other person by reason of such compliance or obedience.

                  (f)  The Escrow Agent shall not have any responsibility or
liability for the completeness, correctness or accuracy of any transactions
between Purchaser, on the one hand, and Sellers, on the other hand.

                  (g)  In the event that the Escrow Agent shall be uncertain
as to its duties or rights hereunder or shall receive instructions with respect
to the Escrow Deposit which, in its sole opinion, are in conflict with either
other instructions received by it or any provision of this Agreement, it shall
without liability of any kind, be entitled to hold the Escrow Deposit pending
the resolution of such uncertainty to the Escrow Agent's sole satisfaction, by
final judgment of a court or courts of competent jurisdiction or otherwise, or
the Escrow Agent, at its option, may, in final satisfaction of its duties
hereunder, deposit the Escrow Deposit with the Clerk of the United States
District Court for the Southern District of New York or with the office of the
clerk of registry of any other court of competent jurisdiction.

         5.  LOSS, LIABILITY OR EXPENSES OF ESCROW AGENT. Any loss, liability or
expense (including, without limitation, all expenses reasonably incurred in its
investigation and defense and costs and expenses reasonably incurred in
enforcing this right of


                                     -6-
<PAGE>

indemnification) incurred by the Escrow Agent without gross negligence or 
willful misconduct on the part of the Escrow Agent arising out of or in 
connection with this Agreement shall be satisfied from the Escrow Deposit.

         6.  BANKING DAYS.  If any date on which the Escrow Agent is required 
to make an investment or a delivery pursuant to the provisions hereof is not 
a banking day, then the Escrow Agent shall make such investment or delivery 
on the next succeeding banking day.

         7.  ESCROW COSTS; NO RIGHT OF SET-OFF.  Any fees charged by the 
Escrow Agent in the performance of Escrow Agent's services hereunder shall be 
satisfied from the Escrow Deposit.

             The Escrow Agent acknowledges and agrees that it is holding the 
Escrow Deposit in its capacity as escrow agent and that it has no right to 
apply amounts in the Escrow Deposit against any obligations of (a) Purchaser, 
(b) the Nonconsenting Holders, or (c) the Company owed to the Escrow Agent 
that were not incurred in connection with the transactions contemplated by 
this Agreement.

         8.  NOTICES.

             (a) All communications under this Agreement shall be in
writing and shall be delivered by hand or mailed by overnight courier or by

                                                   Exhibit F to Merger Agreement


                    [Form of Opinion of Purchaser's counsel]

                  The following opinions are to be provided by counsel for 
Purchaser, subject to customary assumptions, limitations and qualifications. 
All capitalized terms used herein without definition shall have the meanings 
set forth in the Merger Agreement.

         1. Purchaser is a corporation duly organized, validly existing and 
in good standing under the laws of the State of Delaware and has all 
requisite corporate power and authority to own, lease and operate its 
properties and to carry on its business as now being conducted. Merger Sub is 
a corporation duly organized, validly existing and in good standing under the 
laws of the State of Delaware and has all requisite corporate power and 
authority to own, lease and operate its properties and to carry on its 
business as now being conducted.

         2. The shares of Purchaser Common Stock to be issued in the Merger 
are duly authorized, and, when issued and delivered in accordance with the 
provisions of the Merger Agreement (a) will be validly issued, fully paid and 
nonassessable and free of liens, encumbrances or preemptive or similar rights 
and (b) will not be subject to any restrictions on resale under the 
Securities Act other than restrictions imposed by Rule 145 promulgated under 
the Securities Act.

         3. The authorized capital stock of Purchaser as of the date hereof 
consists of _______ shares of Purchaser Common Stock, _______ shares of Class 
B Common Stock, par value $.02 per share and _______ shares of Purchaser 
Preferred Stock. As of the date hereof, (a) _______ shares of Purchaser 
Common Stock were issued and outstanding, (b) _______ shares of Class B 
Common Stock were issued and outstanding, (c) _______ shares of Purchaser 
Preferred Stock were issued and outstanding and (d) no shares of Purchaser 
Common Stock were issued and held in the treasury of Purchaser. No other 
capital stock of Purchaser is authorized or issued. All issued and 
outstanding shares of Purchaser Common Stock are duly authorized, validly 
issued, fully paid and non-assessable. Purchaser is the record and beneficial 
owner of 100% of the issued and outstanding capital stock of Merger Sub.

         4. Each of Purchaser and Merger Sub has all requisite corporate 
power and authority to execute and deliver the Merger Agreement, the 
Registration Rights Agreement and the Escrow Agreement (each a "Transaction 
Document") and to consummate the transactions contemplated thereby, 
including, without limitation, the due authorization and approval for 
issuance of the Purchaser Common Stock issuable in the Merger. The execution 
and delivery of the Transaction Documents and the consummation of the 


                                     
<PAGE>

transactions contemplated thereby, including, but not limited to, the Merger, 
have been duly and validly authorized by each of the respective Boards of 
Directors of Purchaser and Merger Sub, as appropriate, and no other corporate 
proceedings on the part of Purchaser or Merger Sub are necessary to authorize 
the execution and delivery of the Transaction Documents or to consummate the 
transactions contemplated thereby. Each Transaction Document has been duly 
and validly executed and delivered by each of Purchaser and Merger Sub and 
constitutes the legal, valid and binding agreements of each of Purchaser and 
Merger Sub, enforceable against each of Purchaser and Merger Sub in 
accordance with its terms, subject to the Enforceability Exceptions.

         5. To the best of our knowledge, no Consent from or with any 
Governmental Authority on the part of either Purchaser or Merger Sub is 
required in connection with the execution or delivery by either Purchaser or 
Merger Sub of the Transaction Documents or the consummation by either 
Purchaser or Merger Sub of the transactions contemplated thereby other than 
(i) filings with the SEC, state securities laws administrators and the 
National Association of Securities Dealers, Inc., (ii) the filing of the 
Certificate of Merger with the Secretary of State of the State of Delaware in 
accordance with the DGCL, (iii) such filings as may be required in any 
jurisdiction where Merger Sub is qualified or authorized to do business as a 
foreign corporation in order to maintain such qualification or authorization, 
(iv) such other Consents as have been obtained and (v) those Consents that, 
if they were not obtained or made, would not be reasonably likely to have a 
Purchaser Material Adverse Effect.

         6. The execution and delivery of the Transaction Documents, the 
consummation of the transactions contemplated thereby and compliance by 
Purchaser and Merger Sub with any of the provisions thereof (i) will not 
conflict with or result in any breach of any provision of the Certificate or 
Articles of Incorporation or Bylaws of Purchaser or Merger Sub or (ii) to 
such counsel's knowledge, contravene any Law to which Purchaser or Merger Sub 
or any of their respective assets or properties are subject except where such 
contravention would not be reasonably likely to have a Purchaser Material 
Adverse Effect.

         7. To our knowledge, the Registration Statement and all 
post-effective amendments, if any, filed by Purchaser with the SEC have 
become effective under the Act and to such counsel's knowledge, no stop order 
suspending the effectiveness of the Registration Statement has been issued 
and, to our knowledge, no proceedings for that purpose have been instituted 
or are pending or are threatened by the SEC.

                   [Form of Opinion of the Company's counsel]

                  The following opinions are to be provided by counsel for the
Company (allocated between corporate counsel and FCC counsel as appropriate),
subject to customary assumptions, limitations and qualifications. All
capitalized terms used herein without definition shall have the meanings set
forth in the Merger Agreement.

         1. The Company is a corporation duly organized, validly existing and in

_______ shares are issued and outstanding and (iii) _______ shares of preferred
stock, of which _______ are designated Series A Preferred Stock, and of which
______ shares are issued and outstanding. No other capital stock of the Company
is authorized or issued, including without limitation any treasury shares. All
issued and outstanding Shares are duly authorized, validly issued, and, assuming
that the Company has received the consideration it agreed to accept therefor,
are fully paid and non-assessable. Except set forth in Section 2.2 of the
Disclosure Schedule, there are no outstanding rights, subscriptions, warrants,
puts, calls, preemptive rights, options or other agreements of any similar kind
relating to any of the outstanding, authorized but unissued, unauthorized or
treasury shares of the Company or any other security of the Company, and there
is no authorized or outstanding security of any kind convertible into or
exchangeable for any such stock or other security.

         3. Section 2.3 of the Disclosure Schedule lists all of the issued and
outstanding Shares of the Company's capital stock and the record ownership
thereof as of the date thereof. To the knowledge of such counsel, except as set
forth on such Schedule, no other Person has any right to or interest in any of
such Shares. The Company has no Subsidiaries or ownership interests of any kind
in any Person.

         4. The Company has all requisite corporate power and authority to
execute and deliver the Merger Agreement and to consummate the transactions
contemplated thereby. The execution and delivery of the Merger Agreement and the
consummation of the transactions contemplated thereby, including, but not
limited to, the Merger, have been duly and validly authorized by the Board of


                                     
<PAGE>

Directors of the Company and have been approved and adopted by the stockholders
of the Company in accordance with the DGCL. No other corporate proceedings on
the part of the Company are necessary to authorize the execution and delivery of
the Merger Agreement or the consummation of the transactions contemplated
thereby. The Merger Agreement has been duly and validly executed and delivered
by the Company and constitutes the legal, valid and binding agreement of the
Company, enforceable against the Company and in accordance with its terms, ,
subject to the Enforceability Exceptions.

         5. To the best of such counsel's knowledge, no Consent of any
Governmental Authority is required to be obtained by the Company in connection
with the execution or delivery by the Company of the Merger Agreement or the
consummation by the Company of the transactions contemplated thereby other than
(i) the filing of the Certificate of Merger with the Secretary of State of
Delaware in accordance with the DGCL, (ii) such other Consents as have been
obtained and (iii) those Consents that, if they were not obtained and made,
would not be reasonably likely to have a Company Material Adverse Effect.

         6. The execution and delivery of the Merger Agreement, the consummation
of the transactions contemplated thereby and compliance by each of the Company
and the stockholders of the Company with the provisions thereof (i) will not
conflict with or result in any breach of any provision of the Certificate or
Articles of Incorporation or Bylaws of the Company or (ii) to such counsel's
knowledge, contravene any Law to which the Company or any of its respective
assets or properties are subject, except where such contravention would not be
reasonably likely to have a Company Material Adverse Effect.

         7. The Company's LMDS licenses (the "LMDS LICENSES") as of the date
hereof are listed on Schedule 2.10. The grant of the LMDS Licenses has become
effective, no stay of effectiveness of the grant of the LMDS Licenses has been
issued by the FCC, and the LMDS Licenses have not been invalidated by any
subsequent published FCC action. To such counsel's knowledge, no petition for
reconsideration or review of the grant of the LMDS Licenses has been filed with
the FCC. The time provided by Law within which a party in interest may seek
administrative reconsideration or review of the grant of the LMDS Licenses or
for the FCC to give public notice of review of such grant on its own motion has
expired. To such counsel's knowledge, and except for those affecting the
industry generally, as of the date hereof, there are no proceedings pending or
threatened in writing under applicable law against the Company by or before the
FCC which seek the revocation, non-renewal, or material adverse modification of
any of the LMDS Licenses. The Company otherwise has all permits, certificates,
licenses, approvals and other authorizations required in connection with the
operation of its businesses as they are presently being, and have formerly been,


                                     -2-
<PAGE>

operated, except those the absence of which will not be reasonably likely to
have a Company Material Adverse Effect.

                  The FCC's approval of the assignment to Purchaser of the LMDS
Licenses became final on _____, 1999, 40 calendar days following the FCC's
initial public notice of _________, 1999 notifying the public of the FCC's
approval of the assignment to Purchaser of the LMDS Licenses.

10. To the our knowledge, there is no suit, action or proceeding pending or, to
the Company's knowledge, threatened against the Company, nor is there any
judgment, decree, injunction, rule or order of any Governmental Authority
outstanding against the Company.

         shall not include underwriting discounts and commissions.

         (j) "REQUISITE HOLDERS" means Holders holding Registrable Securities
         having a fair market value at the time of no less than $30,000,000.

         (k) "SECURITIES ACT" means the Securities Act of 1933, as amended, or

2.       REGISTRATION.

         (a) RESALE AT CLOSING. The Company will use reasonable best efforts to
         have shares of Common Stock issued to the Holders at the Closing having
         an aggregate market value of approximately $175 million registered
         under the Securities Act for resale by the Holders in an underwritten
         offering (the "Initial Offering") pursuant to a registration statement
         (the "Initial Registration Statement") that has been declared effective
         by the Commission within 30 days following the Closing, which
         registration statement shall be kept effective by the Company until the
         earlier of such time as the Initial Offering is completed or the
         expiration of 60 days following the effectiveness of the Initial


                                      - 2 -

<PAGE>

         Registration Statement. Each Holder shall be entitled to sell its PRO
         RATA share of the shares of Common Stock it receives in the Merger in
         the Initial Offering; PROVIDED, HOWEVER, that any Holder not wishing to
         sell some or all of its PRO RATA portion of shares may elect not to
         participate in the Initial Offering or may elect to sell in such
         offering less than its PRO RATA portion of shares by written notice
         delivered to the Company at least two business days prior to the
         Closing, in which case the aggregate number of shares permitted to be
         sold by all other participating Holders will be increased PRO RATA by
         the number of shares that would otherwise have been allotted to
         non-participating or partially participating Holders. Each Holder
         acknowledges and agrees that the Company may elect to include
         additional shares of Common Stock having an aggregate market value of
         approximately $165 million ($115 million for the Company's account and
         $50 million for the account of a third party) in the Initial
         Registration Statement and the Initial Offering, and may be required to
         include additional shares pursuant to registration rights agreements
         heretofore furnished to WNP. All shares offered in the Initial Offering
         shall be subject to the provisions of subdivision (g) below.

         (b) DEMAND REGISTRATION. At any time and from time to time after 180
         days following the commencement of the Initial Offering, upon written
         request by the Requisite Holders that the Company effect the
         registration under the Securities Act of all or part of the Registrable
         Securities (a "Demand Request"), the Company will use reasonable best
         efforts to register the Registrable Securities which the Company has
         been so requested to register by the Holders under the Securities Act
         for resale by the Holders in an underwritten offering (a "Subsequent
         Offering") pursuant to a registration statement (the "Subsequent
         Registration Statement") that has been declared effective by the
         Commission, which registration statement shall be kept effective by the
         Company until the earlier of such time as the Subsequent Offering is
         completed or the expiration of 60 days following the effectiveness of
         the Subsequent Registration Statement. The Company will use reasonable
         best efforts to have each Subsequent Registration Statement declared
         effective by the Commission within ninety (90) days after receipt of
         such request or within sixty (60) days after receipt of such request if
         the Company is qualified to file a registration statement on Commission
         Form S-3, S-2 or any successor or similar short-form registration
         statement (collectively, "Commission Form S-3"). Subject to subdivision
         (g), the Company may include in such Subsequent Registration Statement
         and Subsequent Offering other securities of the Company for sale, for
         the Company's account or for the account of any other person. Upon
         receipt of a Demand Request, the Company shall promptly give written
         notice of such request to all Holders, and all Holders shall be
         afforded the opportunity to participate in such request as follows:
         subject to subdivision (g), the Company will include in each Subsequent
         Registration Statement and Subsequent Offering such number of
         Registrable Securities of any Holder joining in such request as are
         specified in a written request by the Holder received by the Company
         within 20 days after receipt of such written notice from the Company.

         (c) INCIDENTAL REGISTRATION. For so long as Registrable Securities are
         outstanding, if the Company for itself or any of its security holders
         shall at any time or times after the date hereof determine to register
         under the Securities Act any shares of its capital stock or 


                                      - 3 -

<PAGE>

         other securities (other than: (i) the registration of an offer, sale 
         or other disposition of securities solely to employees of, or other 
         persons providing services to, the Company, or any subsidiary 
         pursuant to an employee or similar benefit plan; or (ii) the 
         issuance of securities in a merger, acquisition or other transaction 
         of the type described in Rule 145 under the Securities Act or a 
         comparable or successor rule, registered on Form S-4 or similar or 
         successor forms), on each such occasion the Company will notify each 
         Holder of Registrable Securities of such determination at least 
         thirty (30) days prior to the filing of such registration statement, 
         and upon the request of any Holder given in writing within twenty 
         (20) days after the receipt of such notice, the Company will cause 
         any of the Registrable Securities specified by any such Holder to be 
         included in such registration statement to the extent such 
         registration is permissible under the Securities Act and subject to 
         the conditions of the Securities Act and subdivision (g) (an 
         "Incidental Registration").

         (d) REGISTRATION STATEMENT FORM. The Company shall, if permitted by
         law, effect any registration requested under Section 2 by the filing of
         a registration statement on Commission Form S-3.

         (e) EXPENSES. The Company shall pay all Registration Expenses incurred
         in connection with the Initial Registration Statement, any Subsequent
         Registration Statement and any Incidental Registration Statement. Those
         Holders of Registrable Securities participating in the Initial
         Offering, any Subsequent Offering and any Incidental Registration shall
         bear their respective PRO RATA share of any applicable underwriting
         discounts and commissions; such participating Holders agree that the
         proceeds received by them upon consummation of any such offering shall
         be net of any and all such discounts and commissions.

         (f) EFFECTIVE REGISTRATION STATEMENT. Neither the Initial Registration
         Statement, a Subsequent Registration Statement, nor an Incidental
         Registration requested pursuant to this Section 2 shall be deemed to
         have been effected until it has become effective with the Commission.
         Notwithstanding the foregoing, a registration statement will not be
         deemed to have been effected if: (i) after it has become effective with
         the Commission, such registration is interfered with by any stop order,
         injunction, or other order or requirement of the Commission or other
         governmental agency or any court proceeding for any reason other than a
         misrepresentation or omission by any Holder; or (ii) the conditions to
         consummation of the Initial Offering or any Subsequent Offering
         contained in the underwriting agreement entered into in connection with
         such registration are not satisfied, other than solely by reason of
         some act or omission by any Holder.

         (G) PRIORITY IN UNDERWRITTEN REGISTRATIONS. If a registration is an
         underwritten registration and the managing underwriters shall give
         written advice to the Company and the Persons requesting such
         registration that, in their opinion, market conditions dictate that no
         more than a specified maximum number of securities could successfully
         be included in such registration, then the maximum number of securities
         included in such registration statement shall be limited to such
         specified number, and the rights of the 


                                      - 4 -

<PAGE>

         Holders to participate in such registration shall be subject to the 
         following cutback provisions:

                  (i) In the case of the Initial Offering, the securities
                  sought to be included in such offering by the Holders shall be
                  excluded on a PRO RATA basis with the securities sought to be
                  included in the Initial Offering by the Company and all other
                  Persons seeking inclusion of securities in such offering
                  (including pursuant to so-called piggyback registration
                  rights), based upon the Holder's, the Company's and the other
                  Persons' relative number of securities sought to be so
                  included until the aggregate market value of the securities
                  sought to be included in such offering by the Holders has been
                  reduced to approximately $125 million, after which any
                  additional securities required to be excluded from such
                  offering in order to comply with the advice of the managing
                  underwriter shall be securities that were to have been offered
                  for the Company's account until the offering includes no such
                  securities, after which the securities sought to be included
                  in such offering by the Holders shall be excluded on a PRO
                  rata basis with the securities sought to be included in the
                  Initial Offering by all other Persons seeking inclusion of
                  securities in such offering (including pursuant to so-called
                  piggyback registration rights), based upon the Holder's and
                  the other Persons' relative number of securities sought to be
                  so included;

                  (ii) In the case of any Subsequent Offering, (a) the
                  securities sought to be included in such offering by the
                  Company for its own account shall have priority for inclusion
                  over any Registrable Securities held by the Holders and (b)
                  Registrable Securities held by the Holders may be excluded on
                  a PRO RATA basis with all other Persons seeking inclusion of
                  securities in such offering pursuant to the exercise of
                  so-called piggyback registration rights, based upon such
                  Holder's and other Persons' relative number of securities
                  sought to be so included; and

                  (iii) If the registration is an Incidental Registration, (a)
                  the securities sought to be registered by the Company for its
                  own account shall have priority for inclusion, (b) the
                  securities sought to be registered for the account of other
                  Persons exercising demand registration rights shall have
                  priority for inclusion to the extent such rights require such
                  priority and (c) Registrable Securities held by the Holders
                  may be excluded on a PRO RATA basis with all other Persons
                  seeking inclusion of securities in such registration pursuant
                  to the exercise of so-called piggyback registration rights,
                  based upon such Holder's and other Persons' relative number of
                  securities sought to be so included.

         (h) BLACKOUT AND POSTPONEMENT. Notwithstanding anything in paragraphs
         (a), (b), and (c) of this Section 2, the Company shall have the right
         (i) to delay any registration of Registrable Securities requested
         pursuant to paragraph (a), (b) or (c) of this Section 2 or (ii) upon
         written notice to the Holders, to prohibit the Holders from selling
         Registrable Securities under the Initial Registration Statement, any
         Subsequent Registration Statement, or any Incidental Registration, in
         any case for up to 120 days if such 


                                      - 5 -

<PAGE>

         registration or sale, as applicable, would, in the judgment of the 
         Company as reflected in an officer's certificate delivered to the 
         Holders, require disclosures that would not be in the Company's best 
         interest to make at such time, as applicable; PROVIDED, HOWEVER, 
         that (i) the Initial Registration Statement and the Initial Offering 
         shall not be delayed or blacked-out for more than 120 days in the 
         aggregate and (ii) registrations other than the Initial Registration 
         Statement shall not be delayed and/or sale prohibitions relating to 
         offerings other than the Initial Offering shall not be in effect 
         pursuant to the provisions of this paragraph (h) for more than 270 
         days during any period of 365 days. The time period during which any 
         sale prohibition relating to the Initial Registration Statement or a 
         Subsequent Registration Statement is in effect under this Section 
         2(h) shall be added to the time period for which the Initial 
         Registration Statement or a Subsequent Registration Statement, as 
         the case may be, is otherwise required to remain effective under 
         this Agreement.

3.       REGISTRATION PROCEDURES.

         (a) If and whenever the Company is required to effect the registration
         of any Registrable Securities under the Securities Act as provided in
         Section 2, the Company, as expeditiously as possible and subject to the
         terms and conditions of Section 2, will:

                  (i) prepare and file with the Commission the requisite
                  registration statement to effect such registration and use its
                  best efforts to cause such registration to become and remain
                  effective;

                  (ii) permit any Holder which, in the reasonable judgment of
                  the Holder, might be deemed to be an underwriter or a
                  controlling person of the Company, to participate in the
                  preparation of such registration statement and to require the
                  insertion therein of material, furnished to the Company in
                  writing, which in the reasonable judgment of such Holder and
                  its counsel should be included and which is not reasonably
                  objected to by the Company and its counsel;

                  (iii) prepare and file with the Commission such amendments
                  and supplements to such registration statement and the
                  prospectus used in connection therewith as may be necessary to
                  keep such registration statement effective and to comply with
                  the provisions of the Securities Act with respect to the
                  disposition of all securities covered by such registration
                  statement until the earlier of such time as all of such
                  securities have been disposed of in accordance with the
                  intended methods of disposition by the seller or sellers
                  thereof set forth in such registration statement or the
                  expiration of 60 days after such registration statement
                  becomes effective (in the case of the Initial Registration
                  Statement or a Subsequent Registration Statement);

                  (iv) furnish to the Holders such number of conformed copies
                  of such registration statement and of each such amendment and
                  supplement thereto (in each case including all exhibits), such
                  number of copies of the prospectus contained in such
                  registration statement (including each preliminary prospectus


                                      - 6 -

<PAGE>

                  and any summary prospectus) and any other prospectus filed
                  under Rule 424 under the Securities Act, in conformity with
                  the requirements of the Securities Act, and such other
                  documents, as the purchaser or any Holder of Registrable
                  Securities to be sold under such registration statement may
                  reasonably request in order to facilitate the distribution of
                  such Registrable Securities;

                  (v) use its best efforts to register or qualify all
                  Registrable Securities covered by such registration statement
                  under such other United States state securities or blue sky
                  laws of such jurisdictions as any Holder of Registrable
                  Securities to be sold under registration statement shall
                  reasonably request, to keep such registration or qualification
                  in effect for so long as such registration remains in effect,
                  and take any other action which may be customary in similar
                  offerings to enable the Holder of Registrable Securities to be
                  sold under such registration statement to consummate the
                  disposition in such jurisdictions of the securities owned by
                  such Holder, except that the Company shall not for any such
                  purpose be required to (a) qualify generally to do business as
                  a foreign corporation in any jurisdiction wherein it would not
                  but for the requirements of this subdivision (v) be obligated
                  to be so qualified, or (b) subject itself to taxation in any
                  such jurisdiction.

                  (vi) use its best efforts to cause all Registrable Securities
                  covered by such registration statement to be registered with
                  or approved by such other United States state governmental
                  agencies or authorities as may be necessary to enable the
                  Holder of Registrable Securities to be sold under such
                  registration statement to consummate the intended disposition
                  of such Registrable Securities;

                  (vii) in the event of the issuance of any stop order
                  suspending the effectiveness of the registration statement, or
                  of any order suspending or preventing the use of any related
                  prospectus or suspending the qualification of any Registrable
                  Securities included in such registration statement for sale in
                  any jurisdiction, the Company shall use its best efforts
                  promptly to obtain the withdrawal of such order;

                  (viii) furnish to the Holders of Registrable Securities to be
                  sold under such registration statement an opinion, dated the
                  effective date of the registration statement, of the
                  independent counsel representing the Company for the purposes
                  of such registration, addressed to the underwriters, if any,
                  and to the Holders making such request, stating that such
                  registration statement has become effective under the
                  Securities Act and that (i) to the best knowledge of such
                  counsel, no stop order suspending the effectiveness thereof
                  has been issued and no proceedings for that purpose have been
                  instituted or are pending or contemplated under the Securities
                  Act; (ii) the registration statement, the related prospectus,
                  and each amendment or supplement thereto, comply as to form in
                  all material respects with the requirements of the Securities
                  Act and the applicable rules and regulations of the Commission
                  thereunder (except that such counsel need express 


                                      - 7 -

<PAGE>

                  no opinion as to financial statements and related schedules 
                  and other projected financial or statistical data contained 
                  therein); (iii) the descriptions in the registration 
                  statement or the prospectus, or any amendment or supplement 
                  thereto, of all legal and governmental matters and 
                  contracts and other legal documents or instruments are 
                  accurate and fairly present the information required to be 
                  shown; and (v) such counsel does not know of any legal or 
                  governmental proceedings, pending or contemplated, required 
                  to be described in the registration statement or 
                  prospectus, or any amendment or supplement thereto, which 
                  are not described as required nor of any contracts or 
                  documents or instruments of a character required to be 
                  described in the registration statement or prospectus, or 
                  any amendment or supplement thereto or to be filed as 
                  exhibits to the registration statement which are not 
                  described and filed as required. Such counsel shall also 
                  opine that, in the course of assisting the Company in 
                  preparing the Registration Statement, nothing has come to 
                  their attention that would cause them to believe that the 
                  Registration Statement (excluding the financial and 
                  statistical information contained therein) contains any 
                  untrue statement of a material fact or omits a material 
                  fact necessary to make the statements therein, in light of 
                  the circumstances under which they were made not misleading.

                  (ix) furnish to the Holders of Registrable Securities to be
                  sold under the Registration Statement a letter, dated the
                  effective date of the registration statement, from the
                  independent certified public accountants of the Company,
                  addressed to the underwriters, if any, and to the Holders
                  making such request, stating that they are independent
                  certified public accountants within the meaning of the
                  Securities Act and that in the opinion of such accountants,
                  the financial statements and other financial data of the
                  Company included in the registration statement or the
                  prospectus, or any amendment or supplement thereto, comply as
                  to form in all material respects with the applicable
                  accounting requirements of the Securities Act. Such letter
                  from the independent certified public accountants shall
                  additionally cover such other financial matters (including
                  information as to the period ending not more than five
                  business days prior to the date of such letter) with respect
                  to the registration in respect of which such letter is being
                  given as the Holders may reasonably request.

                  (x) immediately notify the Holders of Registrable Securities
                  included in such registration statement at any time when a
                  prospectus relating thereto is required to be delivered under
                  the Securities Act, of the happening of any event as a result
                  of which the prospectus included in such registration
                  statement, as then in effect, includes an untrue statement of
                  material fact or omits to state any material fact required to
                  be stated therein or necessary to make the statements therein
                  not misleading in the light of the circumstances under which
                  they were made, and at the request of the Holders promptly
                  prepare and furnish to the Holders a reasonable number of
                  copies of a supplement to or an amendment of such prospectus
                  as may be necessary so that, as thereafter delivered to the
                  purchasers of such securities, such prospectus shall not
                  include an untrue statement of a material 


                                      - 8 -

<PAGE>

                  fact or omit to state a material fact required to be stated 
                  therein or necessary to make the statements therein not 
                  misleading in the light of the circumstances under which 
                  they were made;

                  (xi) otherwise use all reasonable best efforts to comply with
                  all applicable rules and regulations of the Commission, and
                  make available to its security holders, as soon as reasonably
                  practicable, an earnings statement covering the period of at
                  least twelve months, but not more than eighteen months,
                  beginning with the first full calendar month after the
                  effective date of such registration statement, which earnings
                  statement shall satisfy the provisions of Section 11(a) of the
                  Securities Act and Rule 158 thereunder, and not file any
                  amendment or supplement to such registration statement or
                  prospectus to which any Holder shall have reasonably objected
                  in writing on the grounds that such amendment or supplement
                  does not comply in all material respects with the requirements
                  of the Securities Act or of the rules or regulations
                  thereunder, having been furnished with a copy thereof at least
                  two business days prior to the filing thereof to the extent
                  reasonably possible;

                  (xii) provide a transfer agent for all Registrable Securities
                  covered by such registration statement not later than the
                  effective date of such registration statement;

                  (xiii) use all reasonable best efforts to cause to be quoted
                  or listed all Registrable Securities covered by such
                  registration statement on NASDAQ and any securities exchange
                  on which any of the Registrable Securities are then quoted or
                  listed;

                  (xiv) confer with the Stockholders' Representative as to
                  mutually beneficial and appropriate time to schedule the
                  Initial Offering and the first Subsequent Offering and make
                  available the Company's management to participate in roadshow
                  presentations and conference calls with respect to such
                  offerings; and

                  (xv) confer with the Stockholders' Representative as to
                  mutually beneficial and appropriate time to schedule any other
                  underwritten offerings of Company Common Stock that will
                  include Registrable Securities and use all reasonable best
                  efforts to work with the Stockholders' Representative to
                  schedule such offerings so that the Company's management will
                  be able to participate in roadshow presentations and
                  conference calls with respect to any additional Subsequent
                  Offerings in excess of $100 million, the availability of its
                  senior management, however, being subject to conflicting
                  business necessities.

         (b) As a condition to the Company's obligation under this Section with
         respect to any Holder, the Company may require such Holder of
         Registrable Securities to be sold under such registration statement, at
         the Company's expense, to furnish the Company with such information and
         undertakings as it may reasonably request regarding such Holder and the


                                      - 9 -

<PAGE>

         distribution of such securities as the Company may from time to time
         reasonably request in writing.

         (c) Each Holder, by execution of this Agreement, agrees (A) that upon
         receipt of any notice of the Company of the happening of any event of
         the kind described in subdivision (a)(x) of this Section 3, such Holder
         will forthwith discontinue its disposition of Registrable Securities
         pursuant to the registration statement relating to such Registrable
         Securities until the receipt by such Holder of the copies of the
         supplemented or amended prospectus contemplated by subdivision (a)(x)
         of this Section 3 and, if so directed by the Company, will deliver to
         the Company all copies (other than permanent file copies), then in
         possession of the Holders of the prospectus relating to such
         Registrable Securities current at the time of receipt of such notice
         and (B) that it will immediately notify the Company, at any time when a
         prospectus relating to the registration of such Registrable Securities
         is required to be delivered under the Securities Act, of the happening
         of any event as a result of which information previously furnished in
         writing by such Holder to the Company for inclusion in such prospectus
         contains an untrue statement of a material fact or omits to state any
         material fact required to be stated therein or necessary to make the
         statements therein not misleading in the light of the circumstances
         under which they were made. In the event the Company or any such Holder
         shall give any such notice, the period referred to in subdivision
         (a)(iii) of this Section 3 shall be extended by a number of days equal
         to the number of days during the period from and including the giving
         of notice pursuant to subdivision (a)(x) of this Section 3 to and
         including the date when such Holder shall have received the copies of
         the supplemented or amended prospectus contemplated by subdivision
         (a)(x) of this Section 3.

4.       UNDERWRITTEN OFFERINGS.

         (a) UNDERWRITTEN OFFERING. In connection with any underwritten
         offering pursuant to a registration under Section 2, the Company will
         enter into an underwriting agreement with the underwriters for such
         offering, such agreement to be in form and substance reasonably
         satisfactory to all Holders requesting such registration and such
         underwriters in their reasonable judgment and to contain such
         representations and warranties by the Company and such other terms as
         are customarily contained in agreements of that type, including,
         without limitation, indemnities to the effect and to the extent
         provided in Section 6. Each such Holder shall be a party to such
         underwriting agreement and may, at its option, require that any or all
         of the representations and warranties by, and the other agreements on
         the part of, the Company to and for the benefit of such underwriters
         shall also be made to and for the benefit of each such Holder and that
         any or all of the conditions precedent to the obligations of such
         underwriters under such underwriting agreement be conditions precedent
         to the obligations of each such Holder. No Holder shall be required to
         make any representations or warranties to or agreements with the
         Company or the underwriters other than representations, warranties or
         agreements regarding such Holder and its intended method of
         distribution and any other representation required by law.

         (b) SELECTION OF UNDERWRITERS. The Company shall select its customary
         underwriter or, alternatively, an underwriting firm of national
         reputation, with expertise in comparable offerings by companies engaged
         in businesses similar to that of the Company that is reasonably
         satisfactory to the Stockholders' Representative, for the Initial
         Offering, any Subsequent Offering and any underwritten offering
         pursuant to an Incidental Registration.

         (c) HOLDBACK AGREEMENTS. Each Holder agrees, if required by the
         managing underwriter in any offering, not to effect any public sale or
         distribution of Registrable Securities (other than sales pursuant to
         the Initial Registration Statement), any sale or distribution thereof
         pursuant to Rule 144 or 145 under the Securities Act, or any short sale
         thereof or any transaction or series of transactions having a
         substantially similar economic effect during the period beginning, in
         the case of the Initial Registration Statement, on the date hereof and
         ,in the case of each Subsequent and Incidental Registration, beginning
         seven days prior to the effective date of such registration statement,
         and ending on the date 180 days after the Initial Registration
         Statement, any Subsequent Registration Statement or any Incidental
         Registration Statement shall have been declared effective, PROVIDED
         that in the event the Initial Registration Statement shall not have
         been declared effective within 30 days following the Closing Date and a
         majority-in-interest of the Holders participating in the Initial
         Offering shall have voted to be released, in whole or in part, from
         such restrictions, all of the Holders shall be released, in whole or in
         part, as so determined, from such restrictions with respect to the
         Initial Offering. In addition, if (i) the gross proceeds to the Holders
         in the Initial Offering are less than $150 million and a
         majority-in-interest of the Holders participating in such offering vote
         to be released, in whole or in part, from the restrictions contained in
         the preceding sentence or (ii) the gross proceeds to the Holders in any
         Subsequent Offering are less than $30 million and a
         majority-in-interest of all Holders of Registrable Securities vote to
         be released, in whole or in part, from the restrictions contained in
         the preceding sentence then all Holders shall be released from the
         restrictions contained in the preceding sentence with respect to such
         offering, in whole or in part, as so determined.

5.       PREPARATION, REASONABLE INVESTIGATION.

                  In connection with the preparation and filing of each
         registration statement under the Securities Act, the Company will give
         the Stockholders' Representative, the underwriters, if any, and their
         respective counsel and accountants, drafts and final copies of such
         registration statement, each prospectus included therein or filed with
         the Commission and each amendment thereof or supplement thereto, at
         least 5 business days prior to the filing thereof with the Commission,
         and will give each of them such access to its books and records and
         such opportunities to discuss the business of the Company with its
         officers and the independent public accountants who have certified its
         financial statements as shall be necessary, in the opinion of such
         Holders' and such underwriters' respective counsel, to conduct a
         reasonable investigation within the meaning of the 


                                      - 11 -

<PAGE>

         Securities Act.

6.       INDEMNIFICATION AND CONTRIBUTION.

         (a) INDEMNIFICATION BY THE COMPANY. In the event of any registration
         under the Securities Act pursuant to Section 2 of any Registrable
         Securities covered by such registration, the Company will, and hereby
         does, indemnify and hold harmless each Holder of Registrable Securities
         to be sold under such registration statement, each such Holder's legal
         counsel, each other person who participates as an underwriter in the
         offering or sale of such securities (if so required by such underwriter
         as a condition to including the Registrable Securities of the Holders
         in such registration) and each other person, if any, who controls any
         such Holder or any such underwriter within the meaning of the
         Securities Act (collectively, the "Indemnified Parties"), against any
         losses, claims, damages or liabilities, joint or several, to which the
         Holders or underwriter or controlling person may become subject under
         the Securities Act or otherwise, insofar as such losses, claims,
         damages or liabilities (or actions or proceedings, whether commenced or
         threatened, in respect thereof) arise out of or are based upon any
         untrue statement or alleged untrue statement of any material fact
         contained in any registration statement under which such securities
         were registered under the Securities Act, any preliminary prospectus,
         final prospectus or summary prospectus contained therein or any
         document incorporated therein by reference, or any amendment or
         supplement thereto, or any omission or alleged omission to state
         therein a material fact required to be stated therein or necessary to
         make the statements therein not misleading, or arise out of any
         violation by the Company of any rule or regulation promulgated under
         the Securities Act or state securities law applicable to the Company
         and relating to action or inaction required of the Company in
         connection with any such registration, and the Company will reimburse
         the Indemnified Parties for any legal or any other expenses reasonably
         incurred by them in connection with investigating or defending any such
         loss, claim, liability, action or proceeding; PROVIDED, HOWEVER, that
         the Company shall not be liable to any Indemnified Party in any such
         case to the extent that any such loss, claim, damage, liability (or
         action or proceeding in respect thereof) or expense arises out of or is
         based upon any untrue statement or alleged untrue statement or omission
         or alleged omission made in such registration statement, any such
         preliminary prospectus, final prospectus, summary prospectus, amendment
         or supplement in reliance upon and in conformity with written
         information furnished to the Company by such Indemnified Party
         specifically for use therein.

         (b) INDEMNIFICATION BY THE HOLDERS. The Company may require, as a
         condition to including any Registrable Securities of any Holder in any
         registration statement filed pursuant to Section 2, that the Company
         shall have received an undertaking reasonably satisfactory to it from
         such Holder to indemnify and hold harmless (in the same manner and to
         the same extent as set forth in subdivision (a) of this Section 6) the
         Company, each director of the Company, each officer of the Company and
         each other person, if any, who controls the Company within the meaning
         of the Securities Act, with respect to any 


                                      - 12 -

<PAGE>

         statement or alleged statement in or omission or alleged omission 
         from such registration statement, any preliminary prospectus, final 
         prospectus or summary prospectus contained therein, or any amendment 
         or supplement thereto, if, and only if, and only to the extent that, 
         such statement or alleged statement or omission or alleged omission 
         was made in reliance upon and in conformity with information 
         furnished in writing to the Company directly by such Holder 
         specifically for use therein; provided, however, that the obligation 
         of any Holder hereunder shall be limited to an amount equal to the 
         net proceeds received by such Holder upon the sale of Registrable 
         Securities sold in the offering covered by such registration.

         (c) NOTICES OF CLAIMS, ETC. Promptly after receipt by an Indemnified
         Party of notice of the commencement of any action or proceeding
         involving a claim referred to in the preceding subdivisions of this
         Section 6, such Indemnified Party will, if a claim in respect thereof
         is to be made against a party required to provide indemnification (an
         "Indemnifying Party"), give written notice to the latter of the
         commencement of such action, PROVIDED, HOWEVER, that the failure of any
         Indemnified Party to give notice as provided herein shall not relieve
         the Indemnifying Party of its obligation under the preceding
         subdivisions of this Section 6, except to the extent that the
         Indemnifying Party is actually prejudiced by such failure to give
         notice. In case any such action is brought against an Indemnified
         Party, unless in such Indemnified Party's reasonable judgment a
         conflict of interest between such Indemnified and indemnifying parties
         may exist in respect of such claim, the Indemnifying Party shall be
         entitled to participate in and to assume the defense thereof, jointly
         with any other Indemnifying Party similarly notified to the extent that
         it may wish, with counsel reasonably satisfactory to such Indemnified
         Party, and after notice from the Indemnifying Party to such Indemnified
         Party of its election so to assume the defense thereof, the
         Indemnifying Party shall not be liable to such Indemnified Party for
         any legal or other expenses subsequently incurred by the latter in
         connection with the defense thereof other than reasonable costs of
         investigation. No Indemnifying Party shall consent to entry of any
         judgment or enter into any settlement without the consent of the
         Indemnified Party which does not include as an unconditional term
         thereof the giving by the claimant or plaintiff to such Indemnified
         Party of a release from all liability in respect to such claim or
         litigation.

         (d) OTHER INDEMNIFICATION. Indemnification substantially equivalent to
         that specified in the preceding subdivisions of this Section 6 (with
         appropriate modifications) shall be given by the Company and each
         Holder of Registrable Securities included in any registration statement
         with respect to any required registration or other qualification of
         securities under any Federal or state law or regulation of any
         governmental authority, other than the Securities Act.

         (e) INDEMNIFICATION PAYMENT. The indemnification required by this
         Section 6 shall be made by periodic payments of the amount thereof
         during the course of the investigation or defense, as and when bills
         are received or expense, loss, damage or liability is incurred.

         (f) SURVIVAL OF OBLIGATIONS. The obligations of the Company and of the
         Holders under this Section 6 shall survive the completion of any
         offering of Registrable Securities under this Agreement.

         (g) CONTRIBUTION. If the indemnification provided for in this Section
         6 is unavailable or insufficient to hold harmless an Indemnified Party,
         then each Indemnifying Party shall contribute to the amount paid or
         payable to such Indemnified Party as a result of the losses, claims,
         damages or liabilities referred to in this Section 6 an amount or
         additional amount, as the case may be, in such proportion as is
         appropriate to reflect the relative fault of the Indemnifying Party or
         parties on the one hand and the Indemnified Party on the other in
         connection with the statements or omissions which resulted in such
         losses, claims, demands or liabilities as well as any other relevant
         equitable considerations. The relative fault shall be determined by
         reference to, among other things, whether the untrue or alleged untrue
         statement of a material fact or the omission or alleged omission to
         state a material fact relates to information supplied by the
         Indemnifying Party or parties on the one hand or the Indemnified Party
         on the other and the parties' relative, intent, knowledge, access to
         information and opportunity to correct or prevent such untrue statement
         or omission. The amount paid to an Indemnified Party as a result of the
         losses, claims, damages or liabilities referred to in the first
         sentence of this Section 6(g) shall be deemed to include any legal or
         other expenses reasonably incurred by such Indemnified Party in
         connection with investigating or defending any action or claim which is
         the subject of this Section 6. No person guilty of fraudulent
         misrepresentation within the meaning of Section 11(f) of the Securities
         Act shall be entitled to contribution from any Person who was not
         guilty of such fraudulent misrepresentation.

FOR IMMEDIATE RELEASE:

NEXTLINK COMMUNICATIONS TO ACQUIRE WNP COMMUNICATIONS FOR $695 MILLION

- --NEXTLINK to Become Largest Holder of LMDS Wireless Spectrum in North America,
Covering Approximately 95 Percent of the POPs in the United States' Top 30
Markets --

Bellevue, Wash., January 14, 1999 --NEXTLINK Communications, Inc. (Nasdaq:
NXLK), one of the nation's leading providers of competitive telecommunications
services, announced today it reached an agreement to acquire WNP Communications,
Inc. for $695 million, payable in cash and stock. NEXTLINK will pay
approximately 542.1 million to WNP and $152.9 million in license charges to the
Federal Communications Commission. The agreement is subject to Federal
regulatory approvals.

NEXTLINK will receive WNP's 39 A block LMDS (local multipoint distribution
service) wireless licenses covering 98 million POPs and one B block LMDS
wireless license covering 16 million POPs. LMDS is a fixed wireless transmission
technology that provides integrated, two-way digital distribution of multimedia
services using a combination of large, high-quality bandwidth similar to fiber
optic cable, yet delivered wireless via a small rooftop antenna. The company
will use the licenses to build fixed wireless extensions to its local fiber
optic networks planned to cover most major cities in the United States.

NEXTLINK also announced a broad agreement in principle to acquire Nextel
Communications, Inc.'s 50 percent interest in NEXTBAND, a joint venture of
Nextel and NEXTLINK that owns 13 A block LMDS licenses and 29 B block LMDS
licenses for approximately $137.7 million. The acquisition price for Nextel's
interest in NEXTBAND will be based on the same value per megahertz per thousand
POPs as used in the WNP transaction. Nextel will continue to focus on its
successful core business of mobile wireless communications for business.

"This is a very important strategic announcement for NEXTLINK and will allow us
to rapidly extend our local networks to a much broader target audience and
advance our goal of becoming a complete facilities-based, end-to-end provider of
telecommunications services," said Wayne Perry, NEXTLINK's chief executive
officer. "Fixed wireless will give us another important transport and access
capability to complement our local and inter-city fiber networks that are being
developed throughout the United States."

After combining the wireless licenses acquired through WNP with those owned
through its investment in NEXTBAND, NEXTLINK will become the largest owner of
LMDS wireless spectrum in North America, covering approximately 95 percent of
the top 30 markets in the United States.

The company intends to use the wireless licenses to extend and complement its
local fiber networks as well as the company's 16,000 mile inter-city long haul
fiber network called INTERNEXT, which is currently under development and planned
to be completed in 2001. By the end of the year 2000, NEXTLINK expects to have
networks in most of the top 30 markets in the United States. Already, NEXTLINK
operates fiber networks in many of those top markets including Los Angeles, San
Francisco, Dallas, Denver, Miami, Chicago, Atlanta, Philadelphia, Cleveland and
New York City.

"By using fixed wireless as an alternative means to reach our customers, we can
further reduce our reliance on the ILEC, thereby relieving our provisioning
bottleneck, accelerating our installation time, and increasing the number of
on-net buildings we serve," said George Tronsrue, NEXTLINK's president and chief
operating officer. "Our wireless solution will serve as spurs from our SONET
fiber rings in major cities. Since the wireless building antennas are portable,
the combination of fiber and fixed wireless will give us tremendous flexibility
to design our networks with maximum capital efficiency."

"We will have the capability of running the equivalent of up to eight OC-3's per
hub site over our wireless transmission, giving a building significant
telecommunications capacity for voice and data services," continued Tronsrue.
"We can choose the best transmission solution for each customer, giving us cost
and service quality advantages over both the wired-only and wireless-only local
service providers. It's a matter of having all the right tools and then choosing
the best one for the job."

NEXTLINK is currently working with equipment vendors who are developing fixed
wireless technology for the LMDS spectrum and expects to begin testing the
service early this year and begin offering commercial service in limited areas
by the end of the year.

NEXTLINK Communications, Inc. was founded by Craig McCaw in 1994 to provide
local, long distance and enhanced communications services to commercial
customers and is one of the fastest growing competitive telecommunications
providers in the nation. Headquartered in Bellevue, Wash., NEXTLINK currently
operates 22 facilities-based networks providing switched local and long distance
services in 36 markets in 14 states.
