                                PURCHASE AND SALE

         2.1. Excluded Service Agreements. Buyer shall have no obligation to
acquire any Service Agreement and pay for the subscribers served pursuant
thereto to the extent that (i) the Service Agreement is not in writing or has
expired as of the relevant Closing Date; (ii) the Service Agreement does not
grant the rights reasonably required by Buyer to install, maintain and operate
its cable television system on the premises of the MDU Property and/or provide
cable television services to the residents of the MDU Property; (iii) the
Service Agreement contains terms and conditions (financial or operational) that
are materially different than the terms and conditions of the forms of Service
Agreement attached as Exhibits A-1, A-2 and A-3 to this Agreement; (iv) either
Seller or the MDU Property owner which is party to the Service Agreement is in
material default of its obligations thereunder as of the relevant Closing Date;
(v) the MDU Property owner which is party to the Service Agreement is more than
60 days delinquent in payment for cable television services provided by Buyer;
or (vi) Buyer otherwise designates in writing to Seller before the First Closing
Date that it desires to exclude the Service Agreement from the transactions
contemplated by this Agreement; provided, that, Buyer shall have a period of at
least 30 days after it has received true and correct copies of the Service
Agreements in which to make such designation. Any Service Agreement that is
excluded by Buyer from the transactions contemplated by this Agreement pursuant
to this Section 2.1 is referred to in this Agreement as an "Excluded Service
Agreement."

         2.2. Covenant of Purchase and Sale; Assets. Subject to and in
accordance with the terms and conditions set forth in this Agreement, Seller
shall transfer to Buyer, and Buyer shall purchase from Seller, free and clear of
all Liens (except for Permitted Liens), all of Seller's right, title and
interest in and to the following described assets and properties, tangible and
intangible, relating to the MMDS Systems (collectively, the "Assets"):

                                       6
<PAGE>

                  2.2.1. the Service Agreements, subject to the provisions of
         Section 2.1;

                  2.2.2. the On-Premises Equipment directly related to each
         Service Agreement transferred to Buyer; and

                  2.2.3. Seller's customer information files relating to
         Seller's provision of video entertainment services at each MDU Property
         that is covered by a Service Agreement transferred to Buyer.

         2.3. Excluded Assets. Notwithstanding anything to the contrary in this
Agreement, the Assets shall not include the following, which shall be retained
by Seller (the "Excluded Assets"): (i) contracts or agreements, other than the
Service Agreements transferred to Buyer at a Closing, that are held or used by
Seller in connection with the MMDS Systems, including Excluded Service
Agreements, programming agreements, retransmission consent agreements, spectrum
leases, Franchises and pole attachment agreements; (ii) the Licenses, (iii)
insurance policies and rights and claims thereunder; (iv) bonds, letters of
credit, surety instruments, and other similar items; (v) cash and cash
equivalents, including deposits of subscribers of the MMDS Systems; (vi)
Seller's trademarks, trade names, service marks, service names, logos, and
similar proprietary rights; (vii) claims, rights and interests in and to any
refunds for Taxes or fees, including franchising and copyright fees, for periods
prior to the applicable Closing Date; (viii) rights of Seller under any contract
for subscriber billing services and any leased subscriber billing equipment;
(ix) employee benefit plans of any nature and their assets; (x) any interest in
owned or leased real estate (but not including any easement or property right
created under any MDU Agreement transferred to Buyer); (xi) vehicles; (xii)
antennas and set-top boxes used or usable in connection with Seller's video
entertainment services; (xiii) inventories of spare equipment or replacement
parts not located on-premise at an MDU Property that is subject to a MDU
Agreement transferred to Buyer; (xiv) antennas and towers comprising part of the
MMDS Systems, or used in connection with Seller's video entertainment services;
(xv) rights retained by Seller under Section 2.8(i); and (xvi) the rights,
assets and properties described on Schedule 2.3.

         2.4. Assumed Obligations and Liabilities. From and after the relevant
Closing Date with respect to each Service Agreement transferred to Buyer, Buyer
shall assume, and shall thereafter pay, discharge, and perform, as and when due,
the following (the "Assumed Obligations and Liabilities"): (i) those obligations
and liabilities arising from and after the Closing Date under such Service
Agreement; and (ii) all obligations and liabilities arising out of Buyer's
ownership or operation of the Assets related to such Service Agreement. All
obligations and liabilities other than the Assumed Obligations and Liabilities
shall remain and be the obligations and liabilities solely of Seller.

         2.5. Purchase Price. Subject to the adjustments contemplated by Section
2.6 and determined pursuant to Section 2.7, and in consideration for the Assets
and the Non-Competition Covenant contemplated by Section 6.1.6, Buyer shall pay
to Seller, by wire

                                       7
<PAGE>

transfer of immediately available funds, an amount in cash to be determined and
paid as follows (the "Purchase Price"):

                  2.5.1. With respect to each bulk billed Service Agreement
         transferred to Buyer, the Purchase Price shall be equal to the lesser
         of (i) "***" for each Equivalent Basic Subscriber multiplied by the
         number of years (rounding down to the nearest whole year) remaining in
         the then current term of the Service Agreement, not to exceed "***",
         and (ii) the amount, if any, set forth in the Service Agreement which,
         if paid by the owner of the MDU Property, would result in the
         termination of the Service Agreement for such MDU Property prior to the
         expiration of its then current term (a "Buyout Provision"). For
         example, if Seller serves 100 Equivalent Basic Subscribers pursuant to
         a Service Agreement with 9.5 years of remaining term, and there is no
         Buyout Provision, then the Purchase Price for the Assets relating to
         the Service Agreement, including the Service Agreement, would be "***".
         If the remaining term of the Service Agreement were 6.5 years, the
         Purchase Price would be "***". If the remaining term of the Service
         Agreement were 6.5 years and there was a "***" Buyout Provision, then
         the Purchase Price would be "***". Buyer shall pay to Seller the
         aggregate Purchase Price determined pursuant to this Section 2.5.1 on
         the relevant Closing Date, subject to a hold back equal to "***" of
         such Purchase Price (the "Holdback Amount"), which together with
         interest earned thereon, shall be held by Buyer solely as security for
         any claims that may be made by Buyer against Sellers pursuant to
         Article 9 of this Agreement (collectively, "Claims"). Buyer shall pay
         to Seller the remainder of the Holdback Amount, together with accrued
         interest, less any amount required to cover pending Claims, on the
         first anniversary of the Final Closing Date. Sellers shall receive
         interest on the Holdback Amount from and after the relevant Closing
         Date, less any amount applied by Buyer to cover Claims, at the rate per
         annum publicly announced from time to time by the Bank of New York as
         its prime rate. Within 10 days after final reconciliation of any Claim
         that is pending as of the first anniversary of the Final Closing Date,
         Buyer shall pay to Seller the remaining Holdback Amount related to such
         Claim, less any amount applied by Buyer to cover such Claim, with
         interest as provided in the preceding sentence. Notwithstanding the
         foregoing, with respect to the bulk billed MDU Properties listed on
         Schedule 2.5, Buyer shall use commercially reasonable (which shall take
         into account the amount payable by Buyer to Seller pursuant to this
         Agreement) efforts during the term of this Agreement to negotiate and
         enter into a service agreement with respect to each such MDU Property
         (each, a "New Buyer Service Agreement"), and on the Closing Date next
         occurring after execution of any New Buyer Service Agreement, shall pay
         to Seller an amount equal to "***" for each Equivalent Basic Subscriber
         served by Seller at such MDU Property immediately prior to the
         effective date of such New Buyer Service Agreement. Except as set forth
         in the foregoing sentence, Buyer shall have no obligation to Seller
         with respect to the MDU Properties listed on Schedule 2.5.

<PAGE>

                  2.5.2. With respect to each individually billed Exclusive
         Service Agreement transferred to Buyer, the Purchase Price shall be
         equal to "***" for each Converted Subscriber served under such Service
         Agreement multiplied by the number of years (rounding down to the
         nearest whole year) remaining in the then current term of such Service
         Agreement, not to exceed eight years, but in no event exceeding, in the
         aggregate, the amount of any Buyout Provision in such Service Agreement
         (if such Service Agreement contains a Buyout Provision) and in no event
         less than, individually, "***" for each Converted Subscriber served
         pursuant to such Exclusive Service Agreement. Buyer shall pay to Seller
         the Purchase Price determined pursuant to this Section 2.5.2 for each
         Converted Subscriber on the first Closing Date occurring after the date
         such subscriber becomes a Converted Subscriber (provided that such
         subscriber remains a Converted Subscriber on such Closing Date).
         Notwithstanding the foregoing, with respect to the individually billed
         MDU Properties listed on Schedule 2.5, Buyer shall use commercially
         reasonable (which shall take into account the amount payable by Buyer
         to Seller pursuant to this Agreement) efforts during the term of this
         Agreement to negotiate and enter into a New Buyer Service Agreement
         with respect to each such MDU Property. Upon entering into any such New
         Buyer Service Agreement, Buyer shall pay to Seller an amount equal to
         "***" for each Converted Subscriber served by Buyer pursuant to such
         New Buyer Service Agreement. Buyer shall pay such amount to Seller for
         each Converted Subscriber on the first Closing Date occurring after the
         date such subscriber becomes a Converted Subscriber (provided that such
         subscriber remains a Converted Subscriber on such Closing Date). Except
         as set forth in the foregoing sentence, Buyer shall have no obligation
         to Seller with respect to the MDU Properties listed on Schedule 2.5.

                  2.5.3. With respect to each individually billed Non-Exclusive
         Service Agreement transferred to Buyer, the Purchase Price shall be
         equal to the lesser of (i) "***" for each Converted Subscriber served
         under such Service Agreement multiplied by the number of years
         (rounding down to the nearest whole year) remaining in the then current
         term of such Service Agreement, not to exceed eight years, and (ii)
         "***", for each Converted Subscriber served under such Service
         Agreement. Buyer shall pay to Seller the Purchase Price determined
         pursuant to this Section 2.5.3 for each Converted Subscriber on the
         first Closing Date occurring after the date such subscriber becomes a
         Converted Subscriber (provided that such subscriber remains a Converted
         Subscriber on such Closing Date). Notwithstanding the foregoing, in no
         event shall the aggregate Purchase Price for Converted Subscribers
         served pursuant to any Non-Exclusive Service Agreement exceed the
         amount of any Buyout Provision in such Service Agreement (if such
         Service Agreement contains a Buyout Provision) and in no event shall
         the individual Purchase Price for a Converted Subscriber served
         pursuant to any Non-Exclusive Service Agreement be less than "***".
         Notwithstanding the foregoing, with respect to the individually billed,
         non-exclusive MDU Properties listed on Schedule 2.5, Buyer shall use
         commercially

                                       9
<PAGE>

         reasonable (which shall take into account the amount payable by Buyer
         to Seller pursuant to this Agreement) efforts during the term of this
         Agreement to negotiate and enter into a New Buyer Service Agreement
         with respect to each such MDU Property. Upon entering into any such New
         Buyer Service Agreement, Buyer shall pay to Seller an amount equal to
         "***" for each Converted Subscriber served by Buyer pursuant to such
         New Buyer Service Agreement. Buyer shall pay such amount to Seller for
         each Converted Subscriber on the first Closing Date occurring after the
         date such subscriber becomes a Converted Subscriber (provided that such
         subscriber remains a Converted Subscriber on such Closing Date). Except
         as set forth in the foregoing sentence, Buyer shall have no obligation
         to Seller with respect to the MDU Properties listed on Schedule 2.5.

                  2.5.4. With respect to each individually billed Eligible
         Subscriber who is not served pursuant to a Service Agreement, Buyer
         shall pay to Seller a Purchase Price of "***" on the first Closing Date
         occurring after the date such Eligible Subscriber becomes a Converted
         Subscriber (provided that such subscriber remains a Converted
         Subscriber on such Closing Date); and provided, further, that Buyer
         shall have no obligation to pay to Seller a Purchase Price for more
         than an aggregate of "***" such Converted Subscribers. Buyer's only
         payment obligation to Seller with respect to each individually billed
         Eligible Subscriber who is not served pursuant to a Service Agreement
         is as set forth in this Section 2.5.4, and Buyer shall have no
         obligation to Seller with respect to any Eligible Subscriber who
         becomes a customer of Buyer, but does not become and remain a Converted
         Subscriber until the relevant Closing Date, or with respect to any
         payments received by Buyer from Eligible Subscribers or Converted
         Subscribers.

         2.6. Current Items Amount. As soon as practicable after the Final
Closing Date, Buyer or Seller, as appropriate, shall pay to the other the net
amount of the prorations determined pursuant to this Section 2.6 with respect to
the Assets transferred by Seller to Buyer pursuant to this Agreement (the
"Current Items Amount"). As of the relevant Closing Date, the following expenses
shall be prorated, in accordance with generally accepted accounting principles
consistently applied in the United States ("GAAP") with respect to each Service
Agreement (and directly related Assets) transferred to Buyer at such Closing
Date, so that the following expenses for periods prior to and including the
relevant Closing Date shall be for the account of Seller, and the following
expenses for periods after the relevant Closing Date shall be for the account of
Buyer:

                  2.6.1. all payments and charges payable by Seller under the
         Service Agreements;

                  2.6.2. general property Taxes, special assessments, and ad
         valorem Taxes levied or assessed against any of the Assets;

                                       10
<PAGE>

                  2.6.3. sales and use Taxes, if any, payable with respect to
         video entertainment service and related sales under the Service
         Agreements transferred to Buyer;

                  2.6.4. copyright expenses; and

                  2.6.5. all other items of expense relating to the Assets
         during the period prior to the relevant Closing Date;

         provided, however, that Seller and Buyer shall not prorate any items of
         expense payable under any Excluded Assets, all of which shall remain
         and be solely for the account of Seller.

         2.7. Current Items Amounts Calculated. Buyer and Seller shall use good
faith efforts to determine the Current Items Amount within 60 days after the
Final Closing Date. If Buyer and Seller are unable to agree on the Current Items
Amount within the period provided herein, the disputed portion of the Current
Items Amount shall be determined by a partner in a major accounting firm with
substantial audit experience with multichannel video entertainment system
operators, but which is not an auditor of either Buyer or Seller (the "Qualified
Auditor"), and the determination of the Qualified Auditor shall be final and
binding upon the parties. If Buyer and Seller cannot agree with respect to
selection of the Qualified Auditor, Buyer and Seller shall each select an
auditor and those two auditors shall select the Qualified Auditor whose
determination shall be final and binding upon the parties. Buyer shall bear 50%
and Seller shall bear 50% of the expenses arising in connection with the
determination of the Qualified Auditor. Not later than 15 days after Seller and
Buyer shall have finally agreed upon the Current Items Amount, or the actual
Current Items Amount is determined by the Qualified Auditor, Seller or Buyer, as
appropriate, shall pay to the other the Current Items Amount.

         2.8. Accounts Receivable, Deposits and Advance Payments.
Notwithstanding the provisions of Section 2.6 or anything else in this Agreement
to the contrary: (i) Seller shall retain all accounts receivable (and the right
to collect such accounts receivable in the ordinary course) with respect to the
operation of the MMDS Systems; (ii) Seller shall, promptly after the relevant
Closing, issue a credit to each Converted Subscriber or MDU Property owner, as
applicable, in the amount of that portion of any advance payment made to Seller
for Seller's video services which relates to periods after such Closing; and
(iii) Seller shall, promptly after the relevant Closing, refund any deposit made
by a Converted Subscriber or MDU Property owner, as applicable, in connection
with the video services received from the MMDS Systems, to the extent that
Seller is not entitled to retain such deposit under its applicable agreement
with the Converted Subscriber or MDU Property owner, as applicable.

         advisers and lenders, in each case, whose knowledge thereof is

         than from the other party), and (ii) to the extent that such party may,
         in the reasonable judgment of its counsel, be compelled by Legal
         Requirements to disclose any of such information, such party may
         disclose such information if it has used commercially reasonable
         efforts, and has afforded the other the opportunity, to obtain an
         appropriate protective order, or other satisfactory assurance of
         confidential treatment, for the information compelled to be disclosed
         (except with respect to information required to be disclosed under
         applicable federal and state securities laws, which shall be governed
         by Section 5.11.2 below). The non-disclosing party shall reasonably
         cooperate with the disclosing party in obtaining any protective order

to transfer any rights it has in existing wiring, antennas, converter boxes, and
other Excluded Assets to Eligible Subscribers who did not become Converted
Subscribers and to other customers of Seller located in one of the Zip Codes who

         5.14. Service Agreements. Buyer shall have the right to seek a renewal,
extension or replacement (which shall not take effect in any event until and
unless Closing occurs with respect to a Service Agreement, and which shall not
affect the calculation of the Purchase Price with respect to the Service
Agreement) of each Service Agreement (other than Excluded Service Agreements)
that may expire prior to December 31, 2002, in accordance with its terms;
provided, however, that Buyer shall not seek any renewal, extension or
replacement of any such Service Agreement which requires a Consent until such

include the right to contact the owner (or its representative) of the MDU
Property to which the Service Agreement relates, and to negotiate such terms
with respect to the extension, renewal or replacement agreement as Buyer shall
determine in its sole discretion.

action, investigation, suit or proceeding against either party that could delay,
prevent or make illegal the consummation of any transactions contemplated by
this Agreement, the parties will use their commercially reasonable efforts to
(a) respond as promptly as reasonably practicable to any inquiries or requests
received from such Governmental Authority for information or documentation in
connection with such matter and (b) overcome any objections that may be raised
by such Governmental Authority to the transactions contemplated by this
Agreement. Notwithstanding the foregoing, if Buyer

                                       20
<PAGE>

determines in its reasonable discretion that (i) the inquiries or requests for
information and documentation by such Governmental Authority are unduly
burdensome to it, (ii) compliance with such inquiries or requests would result
in the transactions contemplated by this Agreement not being consummated by the
Final Closing Date, or (iii) such action, investigation, suit or proceeding
could result in the imposition by the Governmental Authority of conditions that
would be unduly burdensome to Buyer or would materially change the terms,
conditions or character of the transactions contemplated by this Agreement, then
Buyer may terminate this Agreement by so notifying Seller; provided, that such
termination shall not relieve Buyer of its obligations to Seller with respect to
Converted Subscribers as of the date of termination (including payment of the
Purchase Price for Converted Subscribers), subject to the satisfaction of the
conditions set forth in Section 6.1, and in the event of such termination, and
except as provided in this Section 5.16 and Section 8.2, Buyer and Seller shall
have no further liability or obligation to the other party under this Agreement,
including any Non-Competition Covenant executed by Seller in connection
herewith.

         5.17. Marketing to Eligible Subscribers.

         to Eligible Subscribers who are not served pursuant to a Service
         Agreement, and from and after the relevant Closing Date with respect to
         Eligible Subscribers who are served pursuant to a Service Agreement
         transferred to Buyer, Buyer shall use commercially reasonable efforts
         to market its cable television services to each Eligible Subscriber and
         to maximize the number of Converted Subscribers. Except as provided in
         Section 5.17.2, "commercially reasonable efforts" shall not require
         Buyer to offer an Eligible Subscriber any discounts or other economic
         incentives to become a Converted Subscriber, nor shall it require Buyer
         to advertise or promote its cable television services outside of the
         ordinary course of business.

                  5.17.2. With respect to Eligible Subscribers who reside in
         single family dwelling units and commercial accounts, Buyer shall make,
         within 30 days after Buyer receives a complete and accurate list of
         names and addresses of such Eligible Subscribers, a written offer, in a
         form mutually agreed upon by Buyer and Seller (Seller not to
         unreasonably withhold or delay its consent to Buyer's proposed offer),
         to each Eligible Subscriber soliciting such Eligible Subscriber to
         subscribe to Buyer's cable television service. Such written offer shall
         include free installation, as well as any other promotion that Buyer is
         then offering to similarly situated potential customers in the market
         in which such Eligible Subscriber resides. The written offer shall
         expire four months from the date it is made.

         MDU Property, Buyer shall make a written offer in accordance with the
         provisions of

                                       21

         the Service Agreement that relates to such MDU Property.

date of this Agreement, Seller shall not (i) market its MMDS video entertainment
services, including the ITFS Programming, to, (ii) accept new orders for its
MMDS video entertainment services, including the ITFS Programming, from, and
(iii) resell any video entertainment services provided by others (including DBS

any MDU Property. Except as provided in Section 5.16, the obligations under this
Section 5.18 shall survive the Final Closing Date for a period of five years.

ability to (a) offer, market, sell, provide or otherwise deploy Non-Video
Services (as defined in the Non-Competition Covenant); (b) after the Final
Closing Date, offer and provide the ITFS Programming at no charge to any
Eligible Subscriber who did not become a Converted Subscriber and to any other
customer of Seller located in one of the Zip Codes who was not an Eligible
Subscriber, to the extent such Eligible Subscriber or customer signs an

                                     CLOSING

         7.1. Closings; Time and Place. The closing of the transactions
contemplated by this Agreement shall occur periodically (each, a "Closing"),
upon the satisfaction or waiver of all of the conditions set forth in Sections
6.1 and 6.2, and shall take place at a time and location and in the manner
mutually determined by Buyer and Seller. Except as otherwise agreed by the
parties, the first Closing shall occur on the first business day of the calendar
month immediately following the month in which the condition set forth in
Section 6.1.11 is satisfied (the "First Closing Date"), unless such condition is
satisfied during the last five business days of the calendar month, in which
case the First Closing Date shall be the first business day of the second
calendar month following the month in which such condition is satisfied. Except
as otherwise agreed by the parties, subsequent Closings shall occur on the first
business day of each calendar month following the First Closing Date for a
period of five months (the date of the last such Closing being the "Final
Closing Date"). Subject to the provisions of Section 2.1, it is the intent of
the parties that a Closing occur with respect to each Service Agreement and the
Assets relating thereto, on the first Closing Date following the satisfaction or
waiver of all conditions set forth in Section 6.1 and 6.2 with respect to such
Service Agreement and related Assets. Similarly, it is the intention of the
parties that a Closing occur with respect to each Converted Subscriber on the
first Closing Date following the date on which such Eligible Subscriber became a
Converted Subscriber. Buyer shall have no obligation to pay Seller for any
Eligible Subscriber who is not a Converted Subscriber prior to the Final Closing
Date, notwithstanding that such Eligible Subscriber is or becomes a subscriber
of Buyer's cable television service.

         7.2. Guarantee. If Closings do not occur with respect to Service
Agreements and Converted Subscribers (excluding New Buyer Service Agreements and
Converted Subscribers served pursuant to New Buyer Service Agreements), in the
aggregate, comprising at least "***" of the Base Number of Subscribers (the
"Guaranteed Number"), then Buyer shall pay to Seller, on the Final Closing Date,
an amount equal to "***" multiplied by the excess of the Guaranteed Number over
the actual number of Equivalent Basic Subscribers and Converted Subscribers for
which (i) a Closing has occurred or will occur on the Final Closing Date and
(ii) the Purchase Price has been paid or will be paid on the Final Closing Date
to Seller.

         For purposes of this Section 7.2, the "Base Number of Subscribers" is
the sum of (a) the Equivalent Basic Subscribers served pursuant to all bulk
Service Agreements (excluding any Service Agreements that (1) are not in writing
or have expired as of the Final Closing Date (including those bulk Service
Agreement relating to the MDU

                                       25

Properties listed on Schedule 2.5), (2) do not grant the rights reasonably
required by Buyer to install, maintain and operate its cable television system
on the premises of the MDU Property and/or provide cable television services to
the residents of the MDU Property, (3) contain terms and conditions (financial
or operational) that are materially different than the terms and conditions of
the forms of Service Agreement attached as Exhibits A-1, A-2 and A-3 to this
Agreement, (4) with respect to which, either Seller or the MDU Property owner
which is party to the Service Agreement is in material default of its
obligations thereunder as of the Final Closing Date, or (5) with respect to
which, the MDU Property owner is more than 60 days delinquent in payment for
cable television services previously provided by Buyer), and (b) the lesser of
(y) 5,690 and (z) the aggregate number of Eligible Subscribers.

         7.3. Seller's Obligations. At each Closing, Seller shall deliver or
cause to be delivered to Buyer, with respect to the Service Agreements and
related Assets that are the subject of such Closing, the following:

                  7.3.1. Assignment and Bill of Sale. An Assignment and Bill of
         Sale in the form of Exhibit E transferring the relevant Assets from
         Seller to Buyer.

                  7.3.2. Officer's Certificate. A certificate executed by an
         officer of Seller, dated as of Closing, reasonably satisfactory in form
         and substance to Buyer, certifying that the conditions specified in
         Sections 6.1.1 and 6.1.2 have been satisfied.

                  7.3.3. Books and Records. To the extent not previously
         delivered, copies of all MDU Agreements, customer and subscriber lists,
         and other files and records relating to the transferred Assets.

                  7.3.4. Other. Such other documents and instruments as shall be
         necessary to effect the intent of this Agreement and consummate the
         transactions contemplated hereby.

         7.4. Buyer's Obligations. At each Closing, Buyer shall deliver or cause
to be delivered to Seller, with respect to the Service Agreements and related
Assets that are the subject of such Closing, the following:

                  7.4.1. Purchase Price. The Purchase Price for the relevant
         Assets transferred at Closing and for each new Converted Subscriber as
         of such Closing Date, as determined pursuant to Section 2.5.

                  7.4.2. Assumption Agreement. A fully executed Assumption
         Agreement in the form of Exhibit F pursuant to which Buyer shall
         assume, effective as of the Closing Date, the Assumed Obligations and
         Liabilities with respect to the Assets transferred on such Closing
         Date.

         herein;

                  8.1.3. at any time after the Final Closing Date, upon written

                                    ARTICLE 9
                                 INDEMNIFICATION

         9.1. Indemnification by Seller. From and after the First Closing Date,
and regardless of any investigation made at any time by or on behalf of Buyer or
any information Buyer may have, Seller shall defend, indemnify and hold harmless
Buyer, its affiliates, partners, officers, directors, employees, agents, and
representatives, and any third party claiming by or through any of them, as the
case may be, from and against any and all Losses arising out of or resulting
from:

                  9.1.1. any representations and warranties made by Seller in
         this Agreement or in any Transaction Document not being true and
         accurate when made or when required by this Agreement or such
         Transaction Document to be true and accurate;

                  9.1.2. any failure by Seller to perform any of its material

         9.2. Indemnification by Buyer. From and after the First Closing Date,
Buyer shall defend, indemnify and hold harmless Seller, its affiliates,
shareholders, officers, directors, employees, agents, and representatives, and
any third party claiming by or through any of them, as the case may be, from and
against any and all Losses arising out of or resulting from:

                  9.2.1. any representations and warranties made by Buyer in
         this Agreement or in any Transaction Document not being true and
         accurate when made or when required by this Agreement or such
         Transaction Document to be true and accurate;

                  9.2.2. any failure by Buyer to perform any of its covenants,

         9.3. Claims for Indemnity; Third Party Claims.

                  9.3.1. Whenever a claim for Losses shall arise for which one
         party ("Indemnitee") shall be entitled to indemnification under this
         Article 9, Indemnitee shall notify the indemnifying party
         ("Indemnitor") in writing promptly after the first receipt of notice of
         such claim, and in any event within such period as may be necessary for
         Indemnitor to take appropriate action to resist such claim. Such notice
         shall specify all facts known to Indemnitee giving rise to such
         indemnification rights. The right of Indemnitee for indemnification, as
         set forth in the notice, shall be deemed agreed to by Indemnitor
         unless, within 30 days after receipt of such notice, Indemnitor shall
         notify Indemnitee in writing that it disputes the right of Indemnitee
         to indemnification. If Indemnitee shall be duly notified of such
         dispute, the parties shall attempt to settle and compromise the same
         first by referring such matters to an executive officer of each party
         prior to commencing any Litigation to interpret the terms of this
         Agreement.

                  9.3.2. Upon receipt by Indemnitor of a notice from Indemnitee
         with respect to any claim of a third party against Indemnitee, and
         acknowledgment by Indemnitor (whether after resolution of a dispute or
         otherwise) of Indemnitee's right to indemnification hereunder with
         respect to such claim, Indemnitor shall assume the defense of such
         claim with counsel reasonably satisfactory to Indemnitee and Indemnitee
         shall cooperate to the extent reasonably requested by Indemnitor in
         defense or prosecution thereof and shall furnish such records,
         information and testimony and attend all such conferences, discovery
         proceedings, hearings, trials and appeals as may be reasonably
         requested by Indemnitor in connection therewith. If Indemnitor shall
         acknowledge Indemnitee's right to indemnification and elect to assume
         the defense of such claim, Indemnitee shall have the right to employ
         its own counsel in any such case, but the fees and expenses of such
         counsel shall be at the expense of Indemnitee. If Indemnitor has
         assumed the defense of any claim against

                                       29
<PAGE>

         Indemnitee, Indemnitor shall have the right to settle any claim for
         which indemnification has been sought and is available hereunder;
         provided that, to the extent that such settlement requires Indemnitee
         to take, or prohibits Indemnitee from taking, any action or purports to
         obligate Indemnitee, then Indemnitor shall not settle such claim
         without the prior written consent of Indemnitee, such consent not to be
         unreasonably withheld. If Indemnitor does not assume the defense of a
         third party claim or disputes Indemnitee's right to indemnification,
         Indemnitee shall have the right to defend against such claim until
         Indemnitor's obligation to indemnify is established pursuant to this
         Section 9.3, and Indemnitor shall have the right to participate in the
         defense of such claim through counsel of its choice, at Indemnitor's
         expense, but Indemnitee shall have control over the defense and
         authority to resolve such claim subject to this Section 9.3.

         9.4. Survival of Representations and Warranties and Covenants. Unless
specified otherwise in this Agreement, the representations and warranties of
Seller and Buyer in this Agreement shall survive the Final Closing Date for a
period of 12 months, except for (i) those contained in Sections 3.1, 3.2, 3.3,
the first sentence of Section 3.5, and Sections 3.12, 4.1, 4.2 and 4.3, which
shall survive indefinitely, and (ii) those contained in Sections 3.8, 3.9 and
3.10, which shall survive for 30 days after the expiration of the applicable
statute of limitations. Seller and Buyer shall have no liability under Sections
9.1.1 and 9.2.1, respectively, unless a claim for Losses for which
indemnification is sought thereunder is asserted by Buyer or Seller, as the case
may be, within the applicable survival period. Unless specified otherwise in
this Agreement, the covenants of the parties shall survive the Final Closing
Date indefinitely.

         9.5. Threshold; Limitation on Indemnification. An Indemnitor shall not
be liable for indemnification pursuant to Section 9.1.1 or 9.2.1, as applicable,
unless the amount of such Losses for which the Indemnitor, but for the
provisions of this Section 9.5, would be liable exceeds, on an aggregate basis,
$10,000 (the "Threshold Amount"), provided that the Threshold Amount shall not
apply to Buyer's obligation to pay the Purchase Price pursuant to the terms of
this Agreement. If the Threshold Amount is exceeded, the Indemnitor shall be

                               MADISON OIL COMPANY

                              [MADISON LETTERHEAD]

Dear Mike:

         As we have discussed since various management changes have been put
into effect at Madison Oil Company, you and the other senior employees have been
and remain an important part of the Madison team. So that you know where you
stand as we address the challenges and opportunities facing us, the company
wishes to clarify the following.

TITLE AND DUTIES

         Your title is Vice-President, Exploration and Operations. In this
capacity, you are in charge of directing and supervising exploration and
operational personnel to ensure that your and their responsibilities are carried
out effectively and in accordance with Company goals, objectives, strategies,
policies and procedures. Later you will be asked to provide a formal job
description since changes in the assets or corporate structure of Madison may
bring about increased duties and responsibilities.

REMUNERATION

         In remuneration for your services, the Company shall pay you a base
gross annual salary of US $185,000, which will be paid in 12 equal installments,

TERMINATION OF EMPLOYMENT

         In the event that your employment with Madison is terminated for any
reason other than a dismissal for cause or a voluntary resignation on your part,
you will be entitled to the following:

         o The Company would pay you an amount equal to your monthly salary for
         twelve months following the termination date (less applicable
         withholding and deductions). The first of such monthly payments would
         be mailed to you on the first business day of the month following the
         termination date.

         o In addition, one-half of your unvested stock options of Company stock
         would vest on the termination date. You would have one year from the
         date of your termination to exercise these and your other vested stock
         options.

<PAGE>

         Such termination benefits will only be paid or given to you, however,
if you sign a standard termination agreement at the time of your departure
releasing the company from any liability, agreeing not to use confidential
company information for another employer, and also agreeing not to hire away
other Madison personnel for a reasonable period of time.

LEGAL CONTRACT

         This letter is not written in legal language. However, it is meant to
bind the company as to what we would do in the event of a termination of your
employment. Given the questions you and the other senior employees have asked
about their status, the company wanted you to be aware of the job security that
you have here without waiting for lawyers to draw up formal contracts. If it is
determined that such contracts are an appropriate adjunct to this letter, we
will in due course have documents drawn up.

         At such time, or at any other time, please feel free to raise questions
or make comments of concern to you. We value your services to Madison and want
you to feel comfortable as we all work together to move the company to the next
phase.

                                        Sincerely,

                                        /s/ Herbert L. Brewer
                                        Herbert L. Brewer
                                        Chairman & CEO
                                        Date: 09/10/2001

Accepted:

                                   ATTACHMENT

This Attachment shall be deemed a part of the Employee Letter Agreement (the
"Letter Agreement") executed by and between Madison Oil Company (the "Company")
and Michael J. FitzGerald ("Employee").

         1)       The "standard termination agreement" referred to in the
                  "Termination of Employment" section of the Letter Agreement
                  shall not impose on Employee any obligations or restrictions
                  other than those mentioned in that section of the Letter
                  Agreement.

         2)       In the "Termination of Employment" section of the Letter
                  Agreement, "dismissal for cause" is intended to mean actions
                  of fraud, gross negligence or malfeasance by Employee.

         3)       It is agreed between the Company and Employee that any
                  significant decrease in Employee's position, responsibilities
                  or compensation shall constitute constructive dismissal which,
                  unless accepted by Employee, will enable Employee to the
                  termination benefits provided in the Letter Agreement

         4)       It is further understood that Employee shall receive a $50,000
                  bonus upon the consummation of a business combination with
                  Toreador Resources Corporation. If such combination is not
                  consummated, Employee's stock option price shall be reduced to
                  $0.65 US per share.
