         SECTION 5.05.  PURCHASE PRICE ADJUSTMENT.

                  (a)  As used in this Section 5.05, the following terms shall
have the meaning set forth below:

         "CURRENT ASSETS" means the following Purchased Assets: (i) customer
accounts receivable, including roaming accounts receivable (except any such
accounts receivable owed by either Seller or any Affiliate of either Seller),
excluding an allowance for uncollectible accounts receivable (not including
roaming accounts receivable), calculated as follows: 2% for subscriber
receivables that are less than or equal to 30 days past due, 5% for subscriber
receivables that are between 31 and 60 days past due, 20% for subscriber
receivables that are between 61 and 90 days past due and 100% for subscriber
receivables that are more than 90 days past due, (ii) inventory, including
cellular telephone handsets and ancillary equipment held for sale to
subscribers, valued in accordance with GAAP consistently applied, and (iii)
prepaid items relating to the Purchased Assets, including prepaid rent, property
taxes, utility charges, fees and deposits paid (but excluding prepaid
insurance), all determined as of 12:01 a.m. on the Closing Date in accordance
with GAAP consistently applied. A physical audit of each Seller's inventory will
be taken by representatives of Sellers and Purchaser during the afternoon or
evening prior to the Closing Date, the results of which shall be final and
binding upon the parties (i.e., the physical inventory count shall not be
reviewable by the Independent Accountant pursuant to Section 5.05(d) below) for
purposes of determining the number and type of inventory items existing as of
the Closing, which information shall be used to derive the value of the
inventory of Sellers included as Current Assets and reflected on the Closing
Certificate.

         "CURRENT LIABILITIES" shall mean all Assumed Liabilities (as defined in
Article III above) that are of a type determined to be "current liabilities" in
accordance with GAAP.

         "GAAP" means generally accepted accounting principles consistently
applied.

                  (b)  The Base Price shall be increased (or decreased) by the
amount by which Current Assets exceed (or are less than) Current Liabilities as
of the Closing Date (the "WORKING CAPITAL ADJUSTMENT").

                  (c)  In the event that as of the Closing, a Seller shall have
failed to obtain any consent that is necessary for such Seller to assign to
Purchaser any cell site lease or license that is included in the Purchased
Assets, the Base Price shall be decreased by $200,000 for each cell site lease
or license as to which such Seller failed to obtain the consent that is
necessary to assign to Purchaser such cell site lease or license (the "CELL SITE
LEASE ADJUSTMENT").

                  (d)  Sellers shall prepare and submit to Purchaser, not later
than 5 business days prior to the Closing Date, a written good faith estimate of
the amount of the Working Capital Adjustment and the Cell Site Lease Adjustment
(collectively the "ADJUSTMENTS") in accordance with this Section 5.05 and
Sellers' estimate of the Purchase Price resulting from the Adjustments
("SELLERS' ESTIMATE"). Sellers' Estimate shall be accompanied by supporting
documents, work papers, subscriber records and other data supporting the
Adjustments and

                                      -6-
<Page>

Sellers' Estimate. Sellers' Estimate shall be based upon the books and records
of the Seller Business. Sellers' Estimate shall be accompanied by a certificate
signed by an officer of Sellers certifying that the Sellers' Estimate was
calculated in good faith and in accordance with the provisions of this Section
5.05. After the delivery of Sellers' Estimate and prior to the Closing,
Purchaser and Sellers shall attempt to resolve any disputes between Sellers and
Purchaser with respect to Sellers' proposed Adjustments. In connection
therewith, Purchaser shall have full access to Sellers' records related to
Sellers' proposed Adjustments. Prior to Closing, Purchaser shall advise Sellers
in writing as to any dispute Purchaser has with Sellers' Estimate and provide to
Sellers Purchaser's calculation of the Adjustments and the Purchase Price,
accompanied by a certificate signed by a senior officer of Purchaser certifying
that Purchaser's calculation was made in good faith and supporting documents and
information, to the extent the same is available to Purchaser ("PURCHASER'S
ESTIMATE"). In the event Purchaser's Estimate of the Purchase Price is less than
$100,000 less than Sellers' Estimate, the Closing shall proceed with the
Purchase Price based upon Sellers' Estimate. In the event the Purchaser's
Estimate of the Purchase Price is more than $100,000 less than Sellers'
Estimate, then the mid-point between Sellers' Estimate and Purchaser's Estimate
shall be used as the Purchase Price for purposes of Closing.

                  (e)  Within 60 days after the Closing Date, Sellers shall
deliver to Purchaser a certificate (the "CLOSING CERTIFICATE") signed by a
senior officer of ACC Tennessee providing a compilation of the Working Capital
Adjustment to be made pursuant to this Section 5.05 including any changes in the
Working Capital Adjustment, used to determine the Purchase Price at Closing,
together with a copy of any supporting documents, work papers, subscriber
records and other data relating to such Closing Certificate and such other
supporting evidence as Purchaser may reasonably request either prior to or after
delivery thereof. If Purchaser shall conclude that the Closing Certificate does
not accurately reflect the adjustment to be made to the Base Price in accordance
with this Section 5.05, Purchaser shall, within 40 days after their receipt of
the Closing Certificate (such 40 day period being referred to as the "RESPONSE
PERIOD"), deliver to Sellers a written statement of any discrepancies believed
to exist. If Purchaser fails to so notify Sellers of any discrepancies, then the
calculation of the Purchase Price set forth in the Sellers' Closing Certificate
shall be controlling for all purposes hereof and Purchaser or Sellers, as the
case may be, shall on or before the fifth day following the expiration of the
Response Period pay to the other the amount which it is obligated to pay in
accordance with the Closing Certificate. On or before the fifth day following
the earlier to occur of the expiration of the Response Period and the date
Sellers receive Purchaser's statement of discrepancies, Purchaser or Sellers, as
the case may be, shall pay the other the amount, if any, as to which there is no
discrepancy. Purchaser and Sellers shall use good faith efforts to jointly
resolve their discrepancies within 15 days of Sellers' receipt of Purchaser's
written statement of discrepancies, which resolution, if achieved, shall be
binding upon all parties to this Agreement and not subject to further dispute or
review. If Purchaser and Sellers cannot resolve the discrepancies to their
mutual satisfaction within such 15-day period, then the matter shall be
submitted to KPMG, LLP (the "INDEPENDENT ACCOUNTANTS"). In submitting a dispute
to the Independent Accountants, each of the parties shall furnish, at its own
expense, the Independent Accountants and the other party with such documents and
information as the Independent Accountants may reasonable request. Each party
may also furnish to the Independent Accountants such other information and
documents as it deems relevant with the appropriate

                                      -7-
<Page>

copies and notification being given to the other party. The Independent
Accountants may conduct a conference concerning the disagreements between
Sellers and Purchaser at which conference each party shall have the right to
present additional documents, materials and other evidence and to have present
its or their advisors, accountants or counsel. The Independent Accountants shall
promptly render a decision on the issues presented, and such decision shall be
final and binding on the parties. Within 5 days of receipt of the Independent
Accountants' decision with respect to such dispute, if Purchaser is determined
to owe an amount to Sellers, Purchaser shall pay such amount thereof to ACC
Tennessee, and if Sellers are determined to owe an amount to Purchaser, ACC
Tennessee shall pay such amount thereof to Purchaser. All amounts owed by
Purchaser or Sellers in accordance with this Section 5.05(d) shall be paid by
wire transfer of immediately available funds and shall not bear any interest.

         SECTION 5.06. PRELIMINARY TAX CERTIFICATES. At or before the Closing,
each Seller will deliver to Purchaser a tax clearance certificate from the State
of Tennessee, for all periods through the last completed calendar month prior to
the Closing Date (provided that if the Closing Date shall occur during the first
twenty days of a calendar month, the certificate shall be for the period through
the next previous completed calendar month), indicating that all tax returns
required to have been filed by such Seller through and including such date have
been filed and that all Taxes required to be paid by such Seller, as shown on
such returns, have been paid (each, a "PRELIMINARY TAX CERTIFICATE"). If a
Seller is unable to deliver any Preliminary Tax Certificate because such Seller
has not paid all Taxes which it was required to pay to the applicable
jurisdiction, then Purchaser shall have the option of paying such Taxes on the
Closing Date on behalf of such Seller, and reducing the amount of the Sellers'
Closing Payment by the amount of such tax payment, which shall be treated for
purposes of this Agreement as a payment on account of the Purchase Price.
Purchaser shall furnish Sellers at Closing with appropriate evidence of any such
payment. If a Seller is a disregarded entity for purposes of any tax, such
Seller shall also deliver a Preliminary Tax Certificate of each entity in whose
tax returns are reported the tax liability which is attributable to such
Seller's operations (each, a "REGARDED ENTITY").

                                   ARTICLE VI
                                     CLOSING

         Subject to the terms and conditions hereof, the closing of the
transactions contemplated by this Agreement (the "CLOSING") shall take place at
the offices of Edwards & Angell, LLP, 2800 Financial Plaza, Providence, Rhode
Island 02903, on the date (the "CLOSING DATE") which is the latest of (a) the
2nd day after the date that the FCC's consent to the assignment of the Cellular
Authorizations from License Sub to the Purchaser becomes a Final Order (as
defined in Section 10.04), (b) the fifth (5th) day after the expiration or early
termination of the waiting period under the Hart-Scott-Rodino Antitrust
Improvements Act of 1976, as amended (the "HART-SCOTT-RODINO ACT") (if
applicable to the transactions contemplated by this Agreement) or (c) the date
on which all conditions to Closing set forth in Articles X and XI hereof have
been satisfied or waived; provided if such latest date is not a business day,
the Closing Date shall be the next following business day.

         Sellers hereby jointly and severally represent, warrant, covenant and
agree, as of the date hereof and also at and as of the Closing Date (except to
the extent that a representation or warranty is given as of a particular date in
which case such representation or warranty shall be made only as of such
particular date), which representations, warranties, covenants and agreements,
together with all other representations, warranties, covenants and agreements of
Sellers in this Agreement, shall survive the Closing as provided in Section

                       (xx)   any other material Contract not made in the
                  ordinary course of business consistent with past practice.

Sellers have heretofore delivered or made available to Purchaser true and
correct copies of the Assumed Contracts entered into as of the date hereof or
prior to the date hereof that are required to be set forth on SCHEDULE 7.06(a),
including all amendments, supplements and modifications thereto or waivers
currently in effect thereunder.

                  (b)  Except as disclosed on SCHEDULE 7.06(b), no Seller Party
is in Default in any material respect with respect to, nor to Sellers' knowledge
is there any Default in any material respect by the other parties to, any
Assumed Contracts. The Assumed Contracts are in full force and effect,
enforceable against each Seller Party, Affiliate of a Seller Party or AT&T that
is a party thereto in accordance with their terms.

                  (c)  As of July 31, 2001, there were approximately 24,498
subscribers of the Seller Business. SCHEDULE 7.06(c) sets forth the name of each
of the price plans presently in the process of being implemented or presently
covering the active subscribers of the Seller Business, together with the
approximate number of subscribers, as of July 31, 2001, under each such plan,

                                      -12-
<Page>

and the approximate number of such subscribers whose account balances have been
outstanding for more than 60 days.

                  (d)  To the knowledge of Sellers, no party to an Assumed
Contract (which party accounts for $50,000 or more annually in business with
Sellers) has informed any Seller Party of its intent to cancel or otherwise
modify in any material respect, other than in the ordinary course of its
relationship with Sellers or the Seller Business, or to decrease significantly
or limit significantly its purchases, services, supplies or materials under such
Assumed Contract.

                  (e)  Each roaming agreement between a Seller and any carrier
to which such Seller has paid roaming charges in the past 12 months contains
provisions requiring each party thereto to use a pre-call validation ("PV")
system in all markets covered by such roaming agreement and that any call
completed by the serving carrier under such roaming agreement shall be the sole
responsibility of such serving carrier if either (i) a PV request has determined
that the roamer placing such call is not a valid customer of the home carrier or
(ii) the call has been placed using an unauthorized ESN after entry to the
Industry Negative File has become effective. Notwithstanding the foregoing
sentence, in no event shall a Seller be liable for any point to point
validations where the carrier "assumes positive" (as such term is commonly
understood in the industry) at the switch level.

                  (f)  SCHEDULE 7.06(f) sets forth all products and services
that each Seller offers or provide to their subscribers of the Cellular System
in addition to voice cellular service.

         SECTION 7.07. GOVERNMENTAL LICENSES.

                  (a)  License Sub holds all FCC Authorizations and ACC
Tennessee holds those licenses, permits, certificates of public convenience and
necessity of any other governmental body having jurisdiction over the Seller
Business or any Purchased Assets, which are required in connection with the
ownership and operation of the Purchased Assets and the Seller Business as it is
presently being conducted (collectively referred to as the "AUTHORIZATIONS")
except for such licenses, consents, permits, approvals and authorizations for
which the failure to so hold would not be material. All FCC Authorizations are
in full force and effect. Each Seller Party has complied in all material
respects with the terms of the FCC Authorizations. True and correct copies of
the FCC Authorizations, and all amendments thereto to the date hereof, that are
Purchased Assets have been delivered or made available by Sellers to Purchaser.

                  (b)  To Sellers' knowledge, there are no existing
applications, petitions to deny or complaints or proceedings (other than
proceedings affecting the wireless industry generally) pending before the FCC or
any state public utility commission ("STATE PUC") having jurisdiction over the
Seller Business or any Purchased Assets relating to the FCC or State PUC
Authorizations or the Seller Business. No Seller Party has received any notice
of any claim of material Default with respect to any of the FCC and State PUC
Authorizations. None of the FCC Authorizations will be, or could be reasonably
expected to be, adversely affected by consummation of any action of Sellers
taken in connection with the transactions contemplated

                                      -13-
<Page>

hereby or by any other Transaction Document. License Sub is the sole holder of
the FCC Authorizations and ACC Tennessee is the sole holder of all non-FCC
Authorizations.

                  (c)  The map provided by Sellers and attached hereto as
SCHEDULE 7.07(c) is a true and accurate depiction of the current Cellular
Geographic Service Area and boundaries for the Cellular System in all material
respects, as such term is defined in Section 22.911 of the FCC's rules, 47
C.F.R. Section 22.911.

         SECTION 7.08. COMPLIANCE WITH LAWS. Except as set forth on SCHEDULE
7.08, each Seller Party is in material compliance with and there is no material
Default under any statute, law, ordinance, regulation, judgment, decree,
injunction, ruling, order or rule of any federal, state, local, foreign or other
governmental or quasi-governmental agency or body ("LAWS") applicable to the
Seller Business.

         SECTION 7.09. NO CONFLICTS; CONSENTS. Except for compliance with any
applicable requirements of the Hart-Scott-Rodino Act, consent by the FCC to the
assignment of the FCC Authorizations from License Sub to Purchaser and the
consents, authorizations and approvals identified on SCHEDULE 7.09
(collectively, the "REQUIRED CONSENTS") and the registrations, filings and
notices identified on SCHEDULE 7.09 ("REQUIRED NOTICES"), neither the execution
and delivery of this Agreement nor any of the other Transaction Documents by
either Seller nor the performance by any of them of the transactions
contemplated hereby or thereby will result in a Default under any term,
condition or provision of, or require the consent, authorization or approval of,
or any registrations or filings with or notices to, any Person or governmental
or regulatory official, body or authority under, (i) any Law to which any Seller
or any of the Purchased Assets or the Seller Business is subject, (ii) any
Assumed Contract listed on Schedule 7.06(a), or any Authorization to which
either Seller is a party or subject and by which any of the Purchased Assets or
the Seller Business is bound or affected, or (iii) the limited liability company
agreement of either Seller, except with respect to clause (i) above where such
Default or failure to gain a consent or file a notice would not be material.

         SECTION 7.10. LITIGATION AND LEGAL PROCEEDINGS. Except as set forth on

SCHEDULE 7.10, there is no outstanding judgment, order, writ, injunction, decree
or award of any court, arbitrator or governmental or regulatory official, body
or authority (including the FCC or any state body having jurisdiction over the
Seller Business or any Purchased Asset) against any Seller Party affecting the
Seller Business or the Purchased Assets or which questions the validity of any
action taken or to be taken pursuant to this Agreement or in which it is sought
to restrain or prohibit or to obtain damages or other relief in connection with
this Agreement. Except as set forth on SCHEDULE 7.10, there is no litigation,
arbitration, investigation or other proceeding of or before any court,
arbitrator or governmental or regulatory official, body or authority (including
the FCC or any state body having jurisdiction over the Seller Business or any
Purchased Asset) pending, or, to Sellers' knowledge, threatened, against any
Seller Party the result of which, alone or in the aggregate, could reasonably be
expected to adversely affect the Seller Business, the Purchased Assets or the
transactions contemplated by this Agreement, and Sellers have no knowledge of
any reasonably likely basis therefor.

         SECTION 7.11. SYSTEM EMPLOYEES. SCHEDULE 7.11 sets forth a true and
complete list of the names and base salaries of all employees of Dobson Cellular
Systems, Inc. ("DCS") primarily involved in the operation of the Seller Business
(the "SYSTEM EMPLOYEES"). No Person is employed by either Seller in the
operation of the Seller Business. Except as set forth on SCHEDULE 7.11, each
Seller Party and their Affiliates: (i) have in all material respects withheld
and reported all amounts required by law or by agreement to be withheld and
reported with respect to wages, salaries and other payments to System Employees;
(ii) are not liable for any material arrears of wages or any material taxes or
any material penalty for failure to comply with any of the foregoing; and (iii)
are not liable for any material payment to any trust or other fund governed by
or maintained by or on behalf of any court, arbitrator or governmental or
regulatory official, body or authority (including the FCC or any state body
having jurisdiction over the Seller Business or any Purchased Asset), with
respect to unemployment compensation benefits, social security or other benefits
or obligations for System Employees (other than routine payments to be made in
the normal course of business and consistent with past practice). There are no
material pending or to Sellers' knowledge threatened claims or actions against
any Seller Party under any worker's compensation policy or long-term disability
policy involving any System Employee. Except as set forth in SCHEDULE 7.11,
there are no actions, suits, claims or grievances pending, or, to the knowledge
of Sellers, threatened relating to any labor, safety or discrimination matters
involving any System Employee, including, charges of unfair labor practices or
discrimination complaints. No Seller Party nor any of their Affiliates have
engaged in any unfair labor practices within the meaning of the National Labor
Relations Act with respect to any System Employee or the Seller Business. Except
as set forth in SCHEDULE 7.11, no Seller Party nor any of their Affiliates are
presently, nor have they been in the past, a party to, or bound by, any
collective bargaining agreement or other labor union contract applicable to the
Seller Business and no such collective bargaining agreement is being negotiated
by any Seller, DCS or any Affiliate thereof. No consent of any union (or similar
group or organization) is required in connection with the consummation of the
transactions contemplated hereby. There are no pending, or, to Sellers'
knowledge, threatened (a) union representation petitions respecting the System
Employees, (b) efforts being made to organize any of the System Employees, or
(c) strikes, slow downs, work stoppages, or lockouts or threats affecting the
System Employees. No Seller Party has made any representation, warranty or
agreement with any of the System Employees or any other employees of any Seller
Party concerning employment with Purchaser after the Closing.

         SECTION 7.12. SYSTEM EMPLOYEE BENEFITS. Except as set forth on SCHEDULE
7.12 attached hereto, no Seller Party maintains or sponsors any System Employee
Benefit Plans. For purposes of this Agreement, the term "SYSTEM EMPLOYEE BENEFIT
PLANS" means any material plan, program, policy, practice, contract, agreement
or other arrangement providing for compensation, severance, termination pay,
deferred compensation, performance awards, stock or stock-related awards, fringe
benefits or other employee benefits or remuneration of any kind, whether written
or unwritten or otherwise, funded or unfunded, including, each "employee benefit
plan," within the meaning of Section 3(3) of ERISA which is or has been
maintained, contributed to, or required to be contributed to, by any Seller
Party or any ERISA Affiliate (which means any Affiliate or any entity which is
required to be aggregated with any Seller Party under Section 414 of the Code)
for the benefit of any System Employee. Each System Employee Benefit Plan has

                                      -15-
<Page>

been established and administered in material compliance with its terms and the
applicable provisions of ERISA, the Code and other applicable Laws. None of the
System Employee Benefit Plans is subject to Title IV of ERISA (including any
multiemployer plan within the meaning of ERISA Section 3(37) or 4001(a)(3)). No
System Employee Benefit Plan provides, reflects or represents any liability to
provide retiree health to any person for any reason, except as may be required
by COBRA or other applicable statute, and no Seller Party nor any ERISA
Affiliate has represented, promised or contracted (whether in oral or written
form) to any System Employee (either individually or to System Employees as a
group) or any other person that such Employee(s) or other person would be
provided with retiree health, except to the extent required by statute. Except
as set forth on SCHEDULE 7.12, the execution of this Agreement and the
consummation of the transactions contemplated hereby will not (either alone or
upon the occurrence of any additional or subsequent events) constitute an event
under any System Employee Benefit Plan or employment agreement or under any
related trust or loan agreement that will or may result in any payment (whether
of severance pay or otherwise), acceleration, forgiveness of indebtedness,
vesting, distribution, increase in benefits or obligation to fund benefits with
respect to any current or former System Employee.

         SECTION 7.13. TAX MATTERS. Except as set forth on SCHEDULE 7.13
attached hereto, as relates to the Purchased Assets and the Seller Business,
Sellers and each Regarded Entity have timely filed all Tax returns and
statements which they were required to file, and Sellers and each Regarded
Entity have paid all Taxes due prior to the date hereof and will pay when due
(or contest in good faith by appropriate proceedings) all Taxes which may become
due on or before the Closing Date. Except as set forth on SCHEDULE 7.13, Sellers
and each Regarded Entity have not waived any statute of limitations in respect
of Taxes or agreed to an extension of time with respect to a Tax assessment or
deficiency related to the Purchased Assets or the Seller Business. After due
inquiry of each Regarded Entity, to Sellers' knowledge, there are no unresolved
claims raised by any Tax authority concerning the Tax liability of Sellers or
any Regarded Entity related to the Purchased Assets or the Seller Business. All
Taxes related to the Purchased Assets and the Seller Business which Sellers or
any Regarded Entity are required by law to withhold or to collect for payment
have been duly withheld and collected, and have been paid.

         SECTION 7.14.  FINANCIAL STATEMENTS; CHANGES.

                  (a)  Purchaser has heretofore been furnished with the
following information with respect to the Seller Business:

                       (i)  true and complete copies of unaudited statements of
income for the year ended December 31, 2000 (the "HISTORICAL FINANCIAL
STATEMENT"), such income statement being included in SCHEDULE 7.14(a)(i); and

                       (ii) true and complete copies of the unaudited balance
sheet at July 31, 2001 (the "BALANCE SHEET") and the related unaudited statement

income statement being included in SCHEDULE 7.14(a)(ii).

<Page>

                  (b)  Each of the Historical and Current Financial Statements
delivered under Section 7.14(a) above was prepared in accordance with GAAP
applied on a basis consistent with prior periods and past practices except as
otherwise stated therein and with respect to the Current Financial Statements,
subject to normal recurring year-end adjustments and except in each case for the
omission of certain footnotes and other presentation items required by GAAP with
respect to audited financial statements; the balance sheets included in such
Current Financial Statements fairly present the financial condition of the
Sellers with respect to the Cellular System, as of the close of business on the
date thereof and, except for the Excluded Assets, do not include any assets that
are not intended to constitute part of the Purchased Assets after giving effect
to the transactions contemplated hereby; and each of the statements of income
included in such Historical and Current Financial Statements fairly presents the
results of operations of Sellers with respect to the Cellular System for the
fiscal period then ended.

                  (c) Except as set forth on SCHEDULE 7.14(c) attached hereto,
with respect to the Purchased Assets, since July 31, 2001, neither Seller has:

                       (i)   sold, assigned, or transferred any of the material,
assets, properties or rights included in the Purchased Assets (except for the
Excluded Assets and except pursuant to existing Contracts disclosed on any
Schedule to this Agreement or inventory in the ordinary course of business
consistent with past practice);

                       (ii)  entered into any other material transaction
relating to the Seller Business other than in the ordinary course of business
consistent with past practices;

                       (iii)  suffered any material damage, destruction or
casualty loss with respect to the Purchased Assets not covered by insurance;

                       (iv)   suffered any events which, individually or in the
aggregate, have, or could be reasonably expected to, materially adversely affect
the Purchased Assets, the Seller Business or the transactions contemplated by
this Agreement; or

                       (v)    entered into any agreement or understanding to do
any of the foregoing.

         SECTION 7.15. INSURANCE. ACC Tennessee has maintained all policies of
title, liability, fire, worker's compensation and other forms of insurance
(including bonds) that relate to the Purchased Assets and which insure against
risks and liabilities to an extent and in a manner customary in the cellular
industry. All such insurance policies and binders are in full force and effect.
No Seller Party has received any notice of cancellation or non-renewal of any
such policy or binder. No insurance carrier has canceled or reduced any
insurance coverage for any Seller or has given any notice or other indication of
its intention to cancel or reduce any such coverage. ACC Tennessee and DCS have
complied in all material respects with each of such insurance policies and
binders, and have not failed to give any notice or present any claim thereunder
in a due and timely manner.

                                      -17-

         SECTION 7.16. BROKERS. Except for Daniels & Associates, L.P., no Seller
Party has engaged any agent, broker or other person acting pursuant to the
express or implied authority of any Seller Party which is or may be entitled to
a commission or broker or finder's fee in connection with the transactions

                  (b)  For purposes of this Agreement, the term "HAZARDOUS

Seller relating to the Seller Business as set forth on the Balance Sheet and all

this Agreement, including the Closing Certificate, are or will be valid and
genuine, have arisen or will arise solely out of bona fide sales and deliveries
of goods, performance of services and other business transactions in the
ordinary course of the Seller Business consistent with past practices, and the
allowance for collection losses on such balance sheets have been or will be
determined in accordance with GAAP and based upon Sellers' historical experience
in collecting accounts receivable. As of the date of this Agreement, to Sellers'
knowledge, there are no facts or circumstances that will or could reasonably be
expected to result in the allowances for collection losses on the Balance Sheet
being inadequate to cover expected collection losses.

                                  ARTICLE VIII
                           PURCHASER'S REPRESENTATIONS

         Purchaser hereby represents, warrants, covenants and agrees, as of the
date hereof and also at and as of the Closing Date, which representations,
warranties, covenants and agreements, together with all other representations,
warranties, covenants and agreements of Purchaser in this Agreement, shall
survive the Closing as provided in Section 13.06, that:

         SECTION 8.01. ORGANIZATION; QUALIFICATION. Purchaser is a general
partnership duly formed and validly existing under the laws of the state of its
organization. Purchaser has all necessary power and authority to (a) own and
operate its properties, (b) carry on its business as it is now being conducted,
and (c) carry out the transactions contemplated by this Agreement and to own and
operate the Purchased Assets and the Seller Business.

         SECTION 8.02. CONSENTS; AUTHORIZATION; EXECUTION AND DELIVERY OF
AGREEMENT. Except for compliance with any applicable requirements of the
Hart-Scott-Rodino Act and consent by the FCC to the assignment of the FCC
Authorizations from License Sub to Purchaser all necessary consents and
approvals have been obtained by Purchaser for the execution and delivery of this
Agreement. The execution, delivery and performance of this Agreement by
Purchaser has been duly and validly authorized and approved by all necessary
partnership action. This Agreement is a valid and binding obligation of
Purchaser, enforceable against it in accordance with its terms, subject to
bankruptcy, insolvency, reorganization, moratorium or similar laws now or
hereafter in effect affecting creditors' rights generally.

         SECTION 8.03. LITIGATION AND LEGAL PROCEEDINGS. There is no outstanding
judgment, order, writ, injunction, decree or award of any court, arbitrator, or
governmental or regulatory official, body or authority (including the FCC or any
state body having jurisdiction over the Purchaser) against Purchaser, and there
is no litigation, arbitration, investigation or other

                                      -19-
<Page>

proceeding of or before any court, arbitrator or governmental or regulatory
official, body or authority (including the FCC or any state body having
jurisdiction over the Purchaser) pending, or, to Purchaser's knowledge,
threatened, against Purchaser or its assets which individually or in the
aggregate, if adversely determined, could reasonably be expected to result in a
Purchaser Material Adverse Effect or which questions the validity of any action
taken or to be taken pursuant to or in connection with the provisions of this
Agreement or the consummation of the transactions contemplated hereby by the
Purchaser.

         SECTION 8.04. BROKERS. Purchaser has not engaged any agent, broker or
other person acting pursuant to the express or implied authority of Purchaser
which is or may be entitled to a commission or broker or finder's fee in
connection with the transactions contemplated by this Agreement or otherwise
with respect to the sale of the Purchased Assets.

         SECTION 8.05. COMPLIANCE WITH LAWS. Purchaser is in material compliance
with, and is not in material Default under, any Law applicable to its assets or
its business that could reasonably be expected to adversely affect its ability
to hold title to the Purchased Assets at Closing or to fulfill its obligations
under this Agreement and the Transaction Documents from and after Closing.

         SECTION 8.06. FCC MATTERS. Purchaser is fully qualified under the
Communications Act of 1934, as amended (the "COMMUNICATIONS ACT"), to be an FCC
licensee, and to be approved as the assignee of the FCC Authorizations.
Purchaser knows of no reason why the FCC will not grant its consent to the
assignment of the FCC Authorizations from License Sub to Purchaser.

         SECTION 8.07. FINANCIAL ABILITY TO CLOSE. Purchaser specifically
represents and warrants to Sellers that Purchaser at Closing will have the
financial ability to perform its obligations under this Agreement. Furthermore,
Purchaser specifically agrees with Sellers that the obligation of Purchaser to
consummate the transactions contemplated hereby is not subject to any financing
contingency.

         SECTION 8.08. ENVIRONMENTAL SITE ASSESSMENTS. Purchaser has delivered
to Sellers true and complete copies of all transaction screens (to the extent
any transaction screens were performed) and Phase I environmental site
assessment reports (as such terms are commonly understood in the industry) that
were ordered by Purchaser with respect to the Purchased Assets. Sellers
acknowledge that they are not entitled to rely on such reports (since the
consultants did not prepare them for the benefit of Sellers).

                                   ARTICLE IX
                       SELLERS' AND PURCHASER'S COVENANTS

         SECTION 9.01. FINANCIAL STATEMENTS AND CELLULAR SYSTEM INFORMATION. ACC
Tennessee covenants and agrees that from the date of execution of this Agreement
until the Closing, it shall provide Purchaser, as soon as they become available
and in any event within 45 days of the end of each calendar month, the unaudited
balance sheet, statement of income (including detailed revenue classifications),
as well as key operating statistics, including gross subscriber additions,

                                      -20-
<Page>

disconnects and end-of-period number of subscribers for such month, as they
relate to the Seller Business ("INTERIM FINANCIAL STATEMENTS").

         SECTION 9.02.  GOVERNMENTAL APPROVALS.

                  (a)  Purchaser and each Seller covenants and agrees that they
will fully cooperate with each other, and do all things reasonably necessary to
assist each other to obtain all consents and approvals and to file all notices
necessary for assignment to Purchaser of the Authorizations and applications
therefor that are Purchased Assets as soon as practicable after the date hereof.
Purchaser covenants and agrees that it will fully cooperate with each Seller,
and do all things reasonably necessary to assist Sellers to obtain all consents
and approvals and to file all notices necessary for assignment to Purchaser of
the Authorizations and applications therefor that are Purchased Assets,
including the furnishing of financial and other information specifically with
respect to Purchaser reasonably required by the Person whose consent or approval
is being sought. Each Seller covenants and agrees that it will fully cooperate
with Purchaser, and do all things reasonably necessary to assist Purchaser to
file all notices necessary for Purchaser's assumption of the Authorizations that
are Purchased Assets. Each party (the "NOTIFYING PARTY") shall use all
commercially reasonable efforts to provide adequate prior written notice to the
other of any meeting with governmental authorities the purpose of which is to
seek a consent or approval to the transactions contemplated hereby or resulting
from any notice being filed, and upon the Notifying Party's request the other
shall use all commercially reasonable efforts to furnish a representative to
attend meetings with appropriate government authorities for the purpose of
obtaining such consents or approvals and responding to issues resulting from the
filing of a notice. Purchaser and each Seller hereby agree to file the necessary
applications and other filings with the FCC seeking consent to the assignment of
the FCC Authorizations that are Purchased Assets to Purchaser and to diligently
pursue the processing of any such applications and filings and to file for all
other necessary regulatory approvals for the consummation of the transactions
contemplated by this Agreement within fifteen business days of the date of
execution of this Agreement to the extent any such filings have not been made
prior to the date of execution of this Agreement. Neither party shall take any
action or fail to take any action where such act or omission is likely to cause
the FCC not to grant its consent to the assignment of the FCC Authorizations.
Purchaser shall bear the expense of all filing fees in connection with any
filings pursuant to this Section 9.02(a).

                  (b)  Each Seller and Purchaser shall each cooperate and use
their commercially reasonable efforts to prepare and file with the Federal Trade
Commission ("FTC") and the United States Department of Justice ("DOJ") and other
regulatory authorities as promptly as possible, but in any event within fifteen
business days of the date of execution of this Agreement all requisite
applications and amendments thereto together with related information, data and
exhibits necessary to satisfy the requirements of the Hart-Scott-Rodino Act (if
applicable to the transactions contemplated by this Agreement). Purchaser shall
bear all the expense of all filing fees in connection with any filings pursuant
to this Section 9.02(b).

         SECTION 9.03.  THIRD PARTY CONSENTS; CLOSING CONDITIONS.

                                      -21-
<Page>

                  (a)  Each Seller will use commercially reasonable efforts to
obtain all Required Consents and give all Required Notices as promptly as
practicable. Purchaser and each Seller covenant and agree that each of them will
reasonably cooperate with each other, and Purchaser will do all things
reasonably necessary to assist Sellers, to obtain all Required Consents and give
all Required Notices, including the furnishing of financial and other
information specifically with respect to Purchaser, its Affiliates, or Sellers,
as the case may be, reasonably required by the Person whose consent or approval
is being sought. Notwithstanding the foregoing, to the extent that any Assumed
Contract to be sold, assigned, transferred or conveyed to Purchaser, or any
claim, right or benefit arising thereunder or resulting therefrom (individually,
an "INTEREST" and collectively, the "INTERESTS"), is not capable of being sold,
assigned, transferred or conveyed without the approval, consent or waiver of the
issuer thereof, the other party thereto, or any third Person (including a
government or governmental unit), and such approval, consent or waiver has not
been obtained, or if such sale, assignment, transfer or conveyance, or attempted
assignment, transfer or conveyance, of such Assumed Contract would constitute a
breach thereof, and such approval, consent or waiver has not been obtained, this
Agreement shall not constitute an agreement to sell, assign, transfer or convey
such Assumed Contract; provided each Seller shall comply with Section 18.01(b).
Purchaser and each Seller shall use all commercially reasonable efforts to
consummate the transactions contemplated hereby.

                  (b)  Purchaser and each Seller hereby covenant and agree to
use all commercially reasonable efforts to satisfy, or assist the other party in
satisfying, the closing conditions applicable to the Purchaser in Article X
hereof and the Sellers in Article XI hereof prior to the Closing Date.

         SECTION 9.04. CONDUCT OF BUSINESS. (a) From and after the date hereof
until the Closing Date, neither Seller shall, and shall cause DCS not to, engage
in any practice, take any action or enter into any transaction outside the
ordinary course of business without the prior approval of Purchaser, which
approval shall not be unreasonably withheld or delayed, and shall continue to
operate the Seller Business in the ordinary course consistent with past
practices. In furtherance and not in limitation of the foregoing, from and after
the date hereof, Sellers shall and shall cause DCS to:

                       (i)    operate the Seller Business in accordance with the
Authorizations, and comply in all material respects with all Laws applicable to
it, including the regulations of the FCC and any state body having jurisdiction
over the Seller Business or any Purchased Asset;

                       (ii)   except as disclosed on SCHEDULE 9.04(a)(ii), and
except for inventory sold, or retirements of assets, in
each case in the ordinary course of business, refrain from making any sale,
lease, transfer or other disposition of any of the Purchased Assets other than
in connection with replacements with assets of like use and value, or with the
prior written approval of Purchaser, which approval will not be unreasonably
withheld or delayed;

                       (iii)  refrain from amending in any material respect, or
terminating any of the Assumed Contracts, without Purchaser's prior written
approval, which approval will not be unreasonably withheld or delayed;

                                      -22-
<Page>

                       (iv)   maintain insurance on the Purchased Assets
comparable to that maintained prior to the date hereof;

                       (v)    maintain their books and records in accordance
with prior practice;

                       (vi)   take all actions necessary to maintain all of
their rights and interest in, and the validity of, the FCC Authorizations and
not permit any of the FCC Authorizations that are Purchased Assets to expire or
to be surrendered or voluntarily modified in a manner materially adverse to the
operation of the Cellular System, or take any action which would reasonably be
expected to cause the FCC or any other governmental authority to institute
proceedings for the suspension, revocation or limitation of rights under any of
the FCC Authorizations that are Purchased Assets; or fail to prosecute with
commercially reasonable due diligence any pending applications to any
governmental authority; and provide to Purchaser copies of all applications,
correspondence, pleadings and other documents furnished to or received from the
FCC relating to the Cellular System.

                       (vii)  notify Purchaser in writing promptly after
learning of the institution of any material action against either Seller
relating to the Cellular System in any court, or any action against either
Seller relating to the Cellular System before the FCC or any other governmental
agency, and notify Purchaser in writing promptly upon receipt of any
administrative or court order relating to the Purchased Assets or the Cellular
System;

                       (viii) maintain the Seller Business's equipment, systems
and other fixed assets as necessary to maintain the Seller Business's
reliability standards, footprint coverage and network capacity in accordance
with prior practice of each Seller;

                       (ix)   continue in accordance with past practice all
marketing and promotions relating to the maintenance and growth of subscribers
of the Seller Business;

                       (x)    maintain the relations with the suppliers,
customers and distributors of the Seller Business and any others having business
relations with the Seller Business; and

                       (xi)   not cause or permit to occur any of the events or
occurrences described in Section 7.14(c) hereof.

                  (b)  The Purchaser hereby acknowledges and agrees that from
and after the date hereof, either Seller may take any actions determined by
Sellers to be appropriate with respect to the Excluded Assets, including selling
the Excluded Assets.

                  (c)  Each Seller shall use all commercially reasonable efforts
to keep available the services of the System Employees and of all agents of the
Seller Business.

         SECTION 9.05. ACCESS. Upon reasonable prior notice from Purchaser and
provided that significant disruption does not result, each Seller shall, and
shall cause DCS to, (a) give Purchaser and its authorized representatives
reasonable access during all reasonable times to such

                                      -23-
<Page>

Seller's books and records, facilities and assets comprising or relating to such
Seller or the Seller Business, (b) provide such financial and operating data and
other information with respect to each Seller or the Seller Business as
Purchaser may reasonably request, and (c) make their officers, agents and
Affiliates available to Purchaser.

         SECTION 9.06. SYSTEM EMPLOYEES. Upon reasonable notice, each Seller
shall, and shall cause DCS to, provide Purchaser with reasonable access to the
System Employees during normal business hours. Such access shall be in
accordance with applicable law and for the purpose of performing drug tests,
administering employment applications, interviewing employees, and informing
employees about Purchaser benefit plans. Requests for the necessary information
to perform background checks can be included in the employment applications. All
System Employee contact by Purchaser will be done on Sellers' premises and
Purchaser's representative(s) will be accompanied by DCS's Human Resource
representative(s). Purchaser shall have access to System Employees two weeks
before the Closing for the purpose of transition training, provided that such
training does not unreasonably interfere with Sellers' operation of the Seller
Business. At least 45 days prior to the Closing Date, Purchaser shall provide
written notice to Sellers identifying any System Employees to whom Purchaser
does not intend to extend offers of employment. Any medical plans offered by
Purchaser to System Employees hired by Purchaser shall contain no restrictions
or limitations with respect to pre-existing conditions, except to the extent any
such restrictions or limitations actually applied to the System Employees prior
to the Closing Date. Sellers shall, at their option, effective immediately prior
to Closing, cause DCS to terminate or retain the employment of any System
Employees not to be hired by Purchaser and, as soon as practicable after
Closing, shall provide to those terminated System Employees who have not been
employed by Purchaser severance benefits, if any, in accordance with the current
severance arrangements covering the System Employees. Sellers shall also cause
DCS to pay off all accrued vacation and sick time for all terminated System
Employees and all System Employees hired by Purchaser. As of the Closing Date,
all System Employees hired by Purchaser shall cease to participate as active
employees in or accrue benefits under System Employee Benefit Plans or any other
employee benefit plans that are sponsored by any Seller or DCS. From and after
the Closing Date, Purchaser shall cause each employee benefit plan, program,
agreement and arrangement maintained by Purchaser (including any 401(k) plans)
in which any System Employee hired by Purchaser participates to treat all
service accrued or deemed accrued prior to the Closing Date with any Seller or
DCS and their Affiliates and their respective predecessors, successors and
assigns as service rendered to Purchaser and its Affiliates for all purposes
under each such plan, program, agreement and arrangement of Purchaser, other
than for benefit accrual purposes under any defined benefit plan maintained or
sponsored by Purchaser. Purchaser shall take all appropriate action to permit
System Employees hired by Purchaser who were participants in any Seller's or
DCS's 401(k) plan and who received distributions of their account balances from
any Seller's or DCS's 401(k) plan in connection with the consummation of the
transactions contemplated hereby to make a direct rollover pursuant to Section
401(a)(31) of the Code to Purchaser's 401(k) plan. Nothing contained in this
Agreement shall confer upon any System Employee any right with respect to
continued employment by any Seller, DCS or Purchaser following the Closing Date.

         SECTION 9.07.  NON-SOLICITATION; NO SHOP.

                  (a)  From the date of this Agreement until one year from the
Closing Date, Purchaser agrees that it will not, except as expressly provided in
the next sentence, directly or indirectly through any Affiliate or
representative or otherwise, recruit or solicit any management employee of any
Seller, DCS or any of their Affiliates, to become an employee, independent
contractor or consultant of Purchaser or of any of its Affiliates. However,
Purchaser and its Affiliates shall not be prohibited from recruiting,
soliciting, offering to employ or employing any such management employee who (i)
contacts Purchaser or its subsidiaries on his or her own initiative without
solicitation directly or indirectly by Purchaser or its Affiliates or on
Purchaser's or its Affiliates behalf, or (ii) is solicited directly by Purchaser
or its Affiliates, provided that there was no direct or indirect communication
regarding any Seller or DCS or the solicited management employee between the
person making such solicitation and any of Purchaser's representatives who were
given access to Information (as defined in the NDA) of any Seller or DCS in
connection with the negotiation of this Agreement, or (iii) is identified as a
result of a search by Purchaser or its Affiliates for employees through the use
of one or more general advertisements in the media (including trade media) or
through the engagement of one or more firms to conduct searches that are not
targeted or focused on any Seller, DCS and their subsidiaries.

                  (b)  Prior to the Closing, neither any Seller Party nor any
Affiliate thereof shall, directly or indirectly, sell, agree to sell, solicit
inquiries or proposals or furnish any information with respect to, or initiate
or participate in any negotiations or discussions whatsoever concerning any
acquisition or purchase of, any or all of the Purchased Assets outside of the
ordinary course of the Seller Business. Each Seller shall instruct its officers,
trustees, beneficiaries, agents and Affiliates to refrain from doing any of the
above.

         SECTION 9.08. RESTRICTIONS ON CERTAIN ACTIONS. From the date hereof
until the earlier to occur of the Closing Date or the termination of this
Agreement, Purchaser and its Affiliates will not, in any manner, directly or
indirectly, solicit, initiate, encourage or participate in applications, bids,
purchases or negotiations with respect to the acquisition of any interest in an
FCC license, permit, approval or authorization that, if consummated, would have
the effect under the Communications Act of preventing or delaying Purchaser from
consummating the acquisition of the Purchased Assets as contemplated by this
Agreement.

         SECTION 9.09. SUPPLEMENTAL DISCLOSURE. Sellers shall have the right
from time to time prior to the Closing Date to supplement in writing the
Schedules hereto with respect to any event, matter, condition or circumstance
first arising after the date of this Agreement that, if existing or known as of
the date of this Agreement, would have been required to be set forth or
described in the Schedules hereto and that does not arise out of a breach by
either Seller of a covenant in Article IX (other than a breach of a covenant in
Article IX that was outside of such breaching Seller's control) (collectively,
the "UPDATES"). In conjunction with the Updates, Sellers shall also specify the
amount of Losses (as such term is defined in Section 13.01) reasonably expected
by Sellers to result from the Updates (the "EXPECTED LOSS AMOUNT"). In the event
that the aggregate Expected Loss Amount resulting from such Updates is less than
$4,040,000, Purchaser

                                      -25-
<Page>

shall be deemed to have waived its right to terminate this Agreement pursuant to
Section 15.02(c) as a result of such Updates and it shall be required to
consummate the transactions contemplated herein (subject to the satisfaction of
the conditions set forth in Article X), provided, however, that Purchaser shall
be entitled to seek indemnification for any Losses, including any Losses
suffered by Purchaser as a result of the Updates, pursuant to Article XIII. If,
however, the aggregate Expected Loss Amount equals or exceeds $4,040,000.00,
Purchaser shall be entitled to either (i) consummate the transactions
contemplated herein but upon doing so Purchaser shall have automatically and
irrevocably been deemed to have released Sellers and their Affiliates for all
Losses suffered by Purchaser as a result of such Updates in excess of
$4,040,000.00, provided, however, that Purchaser shall be entitled to seek
indemnification pursuant to Article XIII for all Losses suffered by Purchaser as
a result of such Updates up to $4,040,000.00 and for all other Losses not
related to the Updates, or (ii) terminate this Agreement pursuant to Section
15.02(c).

         SECTION 9.10. DISCLAIMER OF OTHER REPRESENTATIONS AND WARRANTIES.
Purchaser acknowledges and agrees that neither Seller makes, nor has made, any
representation or warranty relating to any Seller Party, the Seller Business or
the Purchased Assets other than the representations and warranties of each
Seller expressly set forth in this Agreement. In addition, Purchaser
acknowledges and agrees that neither Seller has made any implied warranties of
merchantability or fitness for a specific purpose with regard to either the
Purchased Assets or the Seller Business. Without limiting the generality of the
disclaimer set forth in the two preceding sentences, neither Seller makes, and
no Seller, their officers, employees, representatives and agents has made, and
shall not be deemed to have made any representations or warranties in the
Confidential Information Memorandum dated as of June, 2001 relating to the sale
of the Purchased Assets, and any supplements or addenda thereto (collectively,
the "OFFERING MEMORANDUM"), any presentation relating to either Seller, the
Seller Business or the Purchased Assets given in connection with the
transactions contemplated by this Agreement, in any filing made by or on behalf
of any Seller with any governmental agency or in any other information provided
to or made available to Purchaser, and no statement contained in the Offering
Memorandum, made in any such presentation, made in any such filing or contained
in any such other information shall be deemed to be a representation or warranty
of any Seller hereunder or otherwise. No Person has been authorized by a Seller
to make any representation or warranty in respect of a Seller, Sellers, the
Seller Business or the Purchased Assets in connection with the transactions
contemplated by this Agreement that is inconsistent with or in addition to the
representations and warranties of each Seller expressly set forth in this
Agreement.

         SECTION 9.11. TRANSITIONAL ARRANGEMENTS. Sellers shall cooperate, and
shall cause DCS to cooperate, with Purchaser in establishing network conversion
and switching conversion arrangements and implementing other transitional
arrangements as reasonably requested by Purchaser provided that such cooperation
shall not unreasonably disrupt Sellers' operation of the Seller Business and no
Seller Party shall be required to incur any out-of-pocket costs in connection
therewith.

         SECTION 9.12. FINAL TAX CLEARANCE CERTIFICATES. Sellers and, if
applicable, each Regarded Entity, shall deliver to Purchaser no later than 60
days after the Closing Date a tax clearance

                                      -26-
<Page>

certificate from the State of Tennessee, for all periods through the Closing
Date, indicating that all tax returns required to have been filed by Sellers
and, if applicable, each Regarded Entity, through and including such date have
been filed and that all Taxes required to be paid by Sellers and, if applicable,
each Regarded Entity, as shown on such returns, have been paid.

         SECTION 9.13. Intentionally omitted.

         SECTION 9.14. CELLULAR ONE CONTRACT. Sellers shall use, and shall cause
DCS to use, commercially reasonable efforts to have the term of the Cellular One
license agreement for the Cellular System (the "CELLULAR ONE AGREEMENT")
extended through the term of the Transition Services Agreement of even date
herewith by and between DCS and Purchaser (the "TRANSITION SERVICES AGREEMENT").
Sellers will in good faith request the approval of Cellular One to the

telecommunications industry), nor (b) any effects of competition resulting from
the offering of personal communication services or other wireless
telecommunications services, will constitute a Seller Material Adverse Effect.

at Closing all claims to insurance proceeds or other rights of Sellers against

name of Sellers.

                                 INDEMNIFICATION

         SECTION 13.01. INDEMNIFICATION BY SELLERS. Notwithstanding the Closing,
subject to the terms of this Article XIII, each Seller jointly and severally
agrees to indemnify and to hold Purchaser and its partners, officers, managers,
and employees (the "INDEMNIFIED PURCHASER PARTIES") harmless from and against
and in respect of any Liability (including consequential damages), action, suit,
demand, judgment, cost of investigation and reasonable attorney fees (but
excluding the Assumed Liabilities and any exemplary or punitive damages, other
than exemplary or punitive damages payable to third parties) (collectively,
"LOSSES"), sustained, incurred or paid by any Indemnified Purchaser Party in
connection with, resulting from or arising out of, directly or indirectly: (a)
any breach of a representation or warranty on the part of any Seller under this
Agreement, (b) any breach or nonfulfillment of any covenant on the part of any
Seller under this Agreement, (c) any Excluded Liability, (d) any Excluded Asset,
(e) the ownership, operation or control by any Seller Party of the Purchased
Assets or the Seller Business for the period prior to the Closing, or (f) any
and all Taxes (i) that are obligations of any Seller or any of their Affiliates
or (ii) which are Pre-closing Taxes (as defined below) that arise out of the
Seller Business or

                                      -32-
<Page>

Purchased Assets (including any such Taxes which become legal liabilities of
Purchaser as a transferee of the Seller Business or the Purchased Assets). For
purposes of this Agreement, the term "Pre-closing Taxes" shall mean (i) any Tax
that is due on or before the Closing Date, (ii) any Tax which is payable for a
Tax period that ends on or before the Closing Date and which is not due until
after the Closing Date, and (iii) with respect to a Tax which is payable for a
Tax period that includes (but does not end on) the Closing Date, the portion of
such Tax that is related to the portion of such Tax period ending on and
including the Closing Date, which portion of such Tax shall (A) in the case of
any Taxes other than gross receipts, sales or use Taxes and Taxes based upon or
related to income, be deemed to be the amount of such Tax for the entire Tax
period (which period, with respect to personal property, ad valorem and real
property Taxes, shall be the calendar year in which the assessment date for such
Tax falls) multiplied by a fraction the numerator of which is the number of days
in the Tax period ending on and including the Closing Date and the denominator
of which is the number of days in the entire Tax period, and (B) in the case of
any Taxes based upon or related to income and any gross receipts, sales or use
Taxes, be deemed equal to the amount which would be payable if the relevant Tax
period ended on and including the Closing Date.

         SECTION 13.02. INDEMNIFICATION BY PURCHASER. Notwithstanding the
Closing, subject to the terms of this Article XIII, Purchaser agrees to
indemnify and to hold each Seller, and their membership interest holders,
managers, officers, employees, representatives and agents (the "INDEMNIFIED
SELLER PARTIES") harmless from and against and in respect of any Losses
suffered, sustained, incurred or paid by any Indemnified Seller Party in
connection with, resulting from or arising out of, directly or indirectly: (a)
any breach of a representation or warranty on the part of Purchaser under this
Agreement, (b) any breach or nonfulfillment of any covenant on the part of
Purchaser under this Agreement, (c) Purchaser's ownership, operation or control
of the Purchased Assets or the Seller Business after the Closing, or (d) the
Assumed Liabilities.

         SECTION 13.03.  NOTICE OF CLAIMS; DEFENSE OF THIRD PARTY.

                  (a)  A party claiming indemnification under this Article XIII
(the "ASSERTING PARTY") must promptly notify (in writing and in reasonable
detail) the party from which indemnification is sought (the "DEFENDING PARTY")
of the nature and basis of such claim for indemnification not later than the end
of the applicable survival period set forth in Section 13.06. If such claim
relates to a claim, suit, litigation or other action by a third party against
the Asserting Party or any Liability to a third party (a "THIRD PARTY CLAIM"),
the Defending Party may elect to assume such Liability and control the defense
of the Third Party Claim at its own expense with counsel selected by the
Defending Party. Assumption of such Liability, as against the Asserting Party,
shall not be deemed an admission of liability as against any such third party.
If the Defending Party assumes liability for the Third Party Claim as against
the Asserting Party and assumes the defense and control of the Third Party Claim
pursuant to this Section 13.03, the Asserting Party may participate in the
defense of such Third Party Claim through counsel of its choosing, but the
Defending Party shall not be liable for any fees and expenses of counsel for the
Asserting Party incurred thereafter in connection with the Third Party Claim,
provided, however, that no Defending Party shall, without the prior written
consent of the Asserting Party, consent to the entry of any judgment against the
Defending Party or enter into any settlement or

                                      -33-
<Page>

compromise which (i) does not include, as an unconditional term thereof, the
giving by the claimant or plaintiff to the Asserting Party of a release, in form
and substance reasonably satisfactory to the Asserting Party from all liability
in respect of such claim or litigation, provided that this requirement shall be
deemed waived to the extent that the Asserting Party does not undertake to
provide and promptly execute and, concurrently with the delivery of any such
release, deliver a corresponding release of the third party claimant with
respect to such Third Party Claim, or (ii) includes terms and conditions that
adversely affect the Asserting Party; provided further, however, that in the
case of clause (ii), the Asserting Party may not unreasonably withhold such
consent.

                  (b) If the Defending Party does not assume liability for, and
the defense of, the Third Party Claim pursuant to this Section 13.03, the
Asserting Party shall have the right (a) to control the defense thereof, and (b)
if the Asserting Party shall have notified the Defending Party of the Asserting
Party's intention to negotiate a settlement of the Third Party Claim (at the
Defending Party's expense to the extent the matter is determined to be subject
to indemnification hereunder), which notice shall include the material terms of
any proposed settlement in reasonable detail, the Asserting Party may settle the
Third Party Claim (at the Defending Party's expense to the extent the matter is
determined to be subject to indemnification hereunder) on terms not materially
inconsistent with those set forth in such notice, unless the Defending Party
shall have notified the Asserting Party in writing of the Defending Party's
election to assume Liability for and the defense of the Third Party Claim
pursuant to this Section 13.03 within ten days after receipt of such notice, and
the Defending Party promptly thereafter shall have taken appropriate action to
implement such defense. The Asserting Party shall not be entitled to settle any
such Third Party Claim pursuant to the preceding sentence unless such settlement
includes an unconditional release of the Defending Party by the Third party
claimant on account thereof, PROVIDED that such requirement shall be deemed
waived to the extent that the Defending Party does not undertake to provide and
promptly execute and, concurrently with delivery of any such release, deliver a
corresponding release of the third party claimant with respect to such Third
Party Claim. The Asserting Party and the Defending Party shall use all
commercially reasonable efforts to cooperate fully with respect to the defense
and settlement of any Third Party Claim covered by this Article XIII.

                  (c) The failure of any Asserting Party to give an indemnifying
party a notice of claim shall not relieve the Defending Party from any liability
in respect of such claim, demand or action which it may have to such Asserting
Party on account of the indemnity agreement of such Defending Party contained in
this Article XIII, except to the extent such Defending Party can establish
actual prejudice and direct damages as a result thereof.

         SECTION 13.04. NON-RECOURSE TO SELLERS' AFFILIATES. Except as otherwise
contemplated by the qualified guarantee and joinder of American Cellular
Corporation contained at the end of this Agreement ("ACC QUALIFIED GUARANTEE"),
the obligations of each Seller to Purchaser under this Agreement and any related
agreements, instruments, documents or certificates are non-recourse to each
Seller's Affiliates and if any Seller is in default hereof or under such other
agreements, instruments, documents or certificates, Purchaser shall not have any
recourse to the

                                      -34-
<Page>

assets of any Affiliate of any Seller. Purchaser's recourse shall be limited
following Closing as provided in Section 13.05 below.

         SECTION 13.05.  LIMITATIONS.  The Defending Party's obligations to
indemnify the Asserting Party pursuant to this Article XIII shall be subject to
the following limitations:

                  (a)  No indemnification under Sections 13.01(a) or 13.02(a)
for any Losses shall be required to be made by the Defending Party until the
aggregate amount of the Asserting Party's Losses exceeds two percent (2%) of the
Purchase Price (the "BASKET"), and then indemnification shall only be required
to be made by the Defending Party to the extent of such Losses that exceed 50%
of the Basket, provided that the foregoing limitation shall not apply to any
intentional breach of a representation or warranty.

                  (b)  The aggregate liability of the Defending Party under
Section 13.01(a) or 13.02(a), as applicable, shall not exceed (i) thirty percent
(30%) of the Purchase Price for the first twelve months after the Closing Date,
and (ii) twenty percent (20%) of the Purchase Price thereafter, provided that
the foregoing limitation shall not apply to any intentional breach of a
representation or warranty.

                  (c)  The indemnification obligation of a Defending Party shall
be reduced to the extent of any available insurance proceeds payable to the
Asserting Party, net of any increased insurance premiums becoming payable by the
Asserting Party to the extent such increase is a direct result of such insurance
proceeds becoming available. The Defending Party shall pay its indemnification
obligations as and when required by this Article XIII and the Asserting Party
shall refund to the Defending Party any such amounts determined to be in excess
of the Defending Party's obligations due to reductions pursuant to this Section
13.05(c). Additionally, the Asserting Party shall refund promptly to the
Defending Party any amount of the Asserting Party's Losses that are subsequently
recovered by the Asserting Party pursuant to a settlement or otherwise.

                  (d)  Notwithstanding anything to the contrary set forth in
this Agreement, Section 13.05(a) through (c) shall not apply to Purchaser's
obligation to pay to ACC Tennessee the Purchase Price in accordance with Article
V.

                  (e)  From and after the Closing Date, the indemnification
rights contained in this Article XIII shall constitute the sole and exclusive
remedies of the parties hereunder and shall supersede and displace all other
rights that either party may have under Law.

         SECTION 13.06. SURVIVAL OF REPRESENTATIONS AND WARRANTIES. All
representations and warranties made by the parties in this Agreement or in any
certificate, schedule, statement, document or instrument furnished hereunder or
in connection with the execution and performance of this Agreement shall survive
for a period lasting eighteen months after Closing, except that (a) any
intentional breach or misrepresentation or fraud shall survive Closing
indefinitely, (b) Section 7.17 shall survive for a period lasting three years
after Closing, and (c) Section 7.13, (i) with respect to federal and state
Taxes, shall survive for a period lasting two years after Closing, and (ii) with
respect to local, municipal and county Taxes, shall survive until

                                      -35-
<Page>

the expiration of the 15-day period commencing on the expiration date of the
relevant statute of limitations period (including any applicable extensions
thereof), if longer than the two-year period previously specified, unless in
each case survival is governed by the preceding clause (a). Any claim by a party
based upon breach of any such representation or warranty made pursuant to
Article XIII or otherwise must be submitted to the other party prior to or at
the expiration of the applicable survival period. In the case of any claim
submitted within such time period, the right of the party submitting the claim
to recover from the other party with respect to such claim shall not be
dependent on the claim being resolved or the losses being incurred within such
time period. Subject to the provisions of Section 9.09, the right to
indemnification hereunder shall not be affected by any investigation or audit
conducted before or after the Closing Date or the actual or constructive
knowledge of any party and each party shall be entitled to rely upon the
representations and warranties set forth herein regardless of any such
investigation or knowledge. The waiver of any condition regarding the accuracy
of any representation or warranty, or regarding the performance of or compliance
with any covenant or obligation, will not affect the right of indemnification or
any other remedy of the waiving party after Closing based on the inaccuracy of
such representation or warranty or the nonperformance of or noncompliance with
such covenant or obligation.

         SECTION 13.07.  PAYMENT.

                  (a)  Upon a determination of Liability under this Article
XIII, the appropriate party shall pay the indemnified party the amount so
determined within 10 business days after the date of such determination. If
there should be a dispute as to the amount or manner of determination of any
indemnity obligation owed under this Agreement the party from which
indemnification is due shall nevertheless pay when due such portion, if any, of
the obligation as shall not be subject to dispute. The difference, if any,
between the amount of the obligation ultimately determined as properly payable
under this Agreement and the portion, if any, theretofore paid shall bear
interest as provided below in Section 13.07(c).

                  (b)  Any items as to which any Indemnified Purchaser Party is
entitled to payment under this Agreement shall first be paid to the Indemnified
Purchaser Party pursuant to the terms of the Escrow Agreement, to the extent
that the then outstanding amount of escrowed funds is sufficient to pay such
items. If the then outstanding amount of the escrowed funds is insufficient to
pay any such item in full (including if all escrowed funds have been released),
the payment of such item as to which the Indemnified Purchaser Party is entitled
to payment under this Agreement and which is not able to be paid from the
escrowed funds shall be the obligation of Sellers and Sellers shall make full
payment of any and all such items to the Indemnified Purchaser Party within 30
calendar days after the date of determination of Liability. If Sellers fail to
make full payment of any item within such period (the "PAYMENT PERIOD"), then
payment of the remaining balance of such item ("UNSATISFIED CLAIMS") shall be
satisfied pursuant to the provisions of the ACC Qualified Guarantee.

                  (c)  If all or part of any indemnification obligation under
this Agreement is not paid when due, then the indemnifying party shall pay the
indemnified party interest on the unpaid amount of the obligation for each day
from the date the amount became due until

                                      -36-
<Page>

payment in full, payable on demand, at the fluctuating rate per annum which at
all times shall be two percentage points in excess of the "Prime Rate" published
from time to time in the "Money Rates" table of the Eastern Edition of The Wall
Street Journal.

                                   ARTICLE XIV
                       CONFIDENTIALITY AND PRESS RELEASES

         SECTION 14.01. CONFIDENTIALITY. The Non-Disclosure Agreement dated
August 31, 2000 between DCS and Purchaser (the "NDA") shall remain in effect in
accordance with its terms, except that it may only be terminated upon
termination of this Agreement, and except that the provisions of Section 7
thereof shall be subject to the provisions of Section 9.07 of this Agreement.
The obligations of Purchaser under the NDA and under this Article XIV shall
terminate as of the Closing, except with respect to Information (as defined in
the NDA) of DCS and of each Seller that does not relate to the Seller Business
that Purchaser is required by the NDA to keep confidential.

         SECTION 14.02. PRESS RELEASES. No press release or public disclosure or
disclosure to any third party, either written or oral, of the existence or terms
of this Agreement shall be made by either Purchaser or Sellers without the
consent of the other subject to the provisions of Section 14.03, and Purchaser
and Sellers shall each furnish to the other advance copies of any release which
they propose to make public concerning this Agreement or the transactions
contemplated hereby and the date upon which Purchaser or Sellers, as the case
may be, propose to make such press release.

         SECTION 14.03. DISCLOSURES REQUIRED BY LAW. This Article XIV shall not,
however, be construed to prohibit any party from making any disclosures to any
governmental authority that it is required to make by Law or from filing this
Agreement with, or disclosing the terms of this Agreement to, any institutional
lender to such party, or prohibit Sellers, Purchaser or any of their Affiliates
from disclosing to its investors, partners, accountants, auditors, attorneys,
parent company and broker/dealers such terms of this transaction as are
customarily disclosed to them in connection with the sale or acquisition of a
cellular telephone system; PROVIDED, HOWEVER, that any such party shall be
informed of the confidential nature of such information and shall agree to keep
such information confidential in accordance with the terms of Section 14.01
hereof; and PROVIDED, HOWEVER, that each party shall provide to the other
reasonable advance copies of any public release except where the provision of
such advance notice is not permissible.

                                   ARTICLE XV
                                   TERMINATION

         SECTION 15.01. BREACHES AND DEFAULTS; OPPORTUNITY TO CURE. Prior to the
exercise by a party of any termination rights afforded under this Agreement, if
either party (the "NON-BREACHING PARTY") believes the other (the "BREACHING
PARTY") to be in breach hereunder, the Non-Breaching Party shall provide the
Breaching Party with written notice specifying in reasonable detail the nature
of such breach, whereupon if such breach is curable the Breaching Party shall
have sixty (60) days from the receipt of such notice to cure such breach to the
reasonable satisfaction of the Non-Breaching Party; PROVIDED, HOWEVER, that if
such breach is

                                      -37-
<Page>

curable but is not capable of being cured within such period and if the
Breaching Party shall have commenced action to cure such breach within such
period and is diligently attempting to cure such breach, then the Breaching
Party shall be afforded an additional sixty (60) days to cure such breach;
PROVIDED, HOWEVER, Purchaser shall have no opportunity to cure the breach of its
obligations to deliver any required portion of the Purchase Price to be
delivered at Closing; and PROVIDED, FURTHER, HOWEVER, that the cure period for a
breach shall in no event extend beyond the Outside Date (as defined in Section
15.02(e)). If the breach is not cured within such time period, then the
Breaching Party shall be in default hereunder and the Non-Breaching Party shall
be entitled to terminate this Agreement (as provided in Section 15.02). This
right of termination shall be in addition to, and not in lieu of, any rights of
the Non-Breaching Party under Article XIII of this Agreement. Notwithstanding
anything to the contrary set forth in this Section 15.01, the provisions of this
Section 15.01 shall not apply in the event Purchaser fails to deliver the
Purchase Price even though all of the closing conditions set forth in Article X
have been satisfied.

         SECTION 15.02.  TERMINATION.  This Agreement may be terminated and the
transactions contemplated herein may be abandoned, by written notice given to
the other party hereto, at any time prior to the Closing:

                  (a)  by mutual written consent of Sellers and Purchaser;

                  (b)  by either Purchaser or Sellers, if any court of competent
jurisdiction in the United States or other United States governmental body shall
have issued an order, decree or ruling or taken any other action permanently
restraining, enjoining or otherwise permanently prohibiting the sale of the
Purchased Assets to Purchaser (which Sellers and Purchaser shall have used all
commercially reasonable efforts to have lifted or reversed) and such order,
decree, ruling or other action shall have become final and nonappealable;

                  (c)  subject to Section 15.01, by Purchaser, if, as of any
date, Sellers shall have breached any of their representations, warranties or
covenants such that the condition set forth in Section 10.01 shall not be
satisfied as of such date;

                  (d)  subject to Section 15.01, by Sellers, if, as of any date,
Purchaser shall have materially breached any of its representations, warranties
or covenants such that the condition set forth in Section 11.01 shall not be
satisfied as of such date; or

                  (e)  by either Sellers or Purchaser if the Closing shall not
have occurred on or before the date that is nine months after the date of this
Agreement (the "OUTSIDE DATE"), unless the failure to have the Closing shall be
due to the failure of the party seeking to terminate this Agreement to perform
in any material respect its obligations under this Agreement required to be
performed by it at or prior to the Closing.

                                   ARTICLE XVI
                                  BROKERS' FEES

         Each party represents and warrants to the other that it shall be solely
responsible for the payment of any fee or commission due to any broker or finder
it has engaged with respect to this transaction and the other party hereto shall
be indemnified for any liability with respect thereto pursuant to Article XIII
hereof.

                                  ARTICLE XVII
                                   ARBITRATION

         Any controversy, dispute or claim (collectively, a "DISPUTE") between
the parties arising out of or relating to this Agreement, or the breach,
termination or validity thereof, shall be finally settled by arbitration in
accordance with the commercial arbitration rules of the American Arbitration
Association ("AAA") then pertaining. However, in all events, these arbitration
provisions shall govern over any conflicting rules that may now or hereafter be
contained in the AAA rules. The arbitration shall be held in the State of New
York unless the parties mutually agree to have the arbitration held elsewhere,
and judgment upon the award made therein may be entered by any court having
jurisdiction in the State of New York; provided however, that nothing contained
in this Article XVII shall be construed to limit or preclude a party from
bringing any action in any court of competent jurisdiction for injunctive or
other provisional relief to compel another party to comply with its obligations
under this Agreement during the pendency of the arbitration proceedings. Any
judgment upon the award rendered by the arbitrators may be entered in any court
having jurisdiction over the subject matter hereof. The arbitrator shall have
the authority to grant any equitable and legal remedies that would be available
in any judicial proceeding instituted to resolve any claim hereunder.

         Any such arbitration will be conducted before a single arbitrator who
shall be chosen by agreement of the parties, or, if the parties cannot agree, in
accordance with the rules of the AAA. The arbitrator shall permit such discovery
as he shall determine is appropriate in the circumstances, taking into account
the needs of the parties and the desirability of making discovery expeditious
and cost-effective. Any such discovery shall be limited to information directly
related to the controversy or claim in arbitration and shall be concluded within
sixty (60) days after appointment of the third arbitrator.

         The substantially prevailing party in any arbitration hereunder, as
determined by the arbitrator, shall be entitled to an award of a percentage of
its reasonable costs incurred in connection therewith, including attorneys'
fees, determined by dividing the amount actually awarded to the prevailing party
by the amount claimed by the prevailing party.

         For any Dispute submitted to arbitration, the burden of proof will be
as it would be if the claim were litigated in a judicial proceeding.

         Upon the conclusion of any arbitration proceedings hereunder, the
arbitrator will render findings of fact and conclusions of law and a written
opinion setting forth the basis and reasons

                                      -39-
<Page>

for any decision reached and will deliver such documents to each party to this
Agreement along with a signed copy of the award.

         The arbitrator chosen in accordance with these provisions will not have
the power to alter, amend or otherwise affect the terms of these arbitration
provisions or the provisions of this Agreement and shall make his decision based
on and in accordance with the provisions of this Agreement.

                                  ARTICLE XVIII
                                  MISCELLANEOUS

         SECTION 18.01.  ADDITIONAL INSTRUMENTS OF TRANSFER.

                  (a)  From time to time after the Closing, each party shall,
if requested by another party, make, execute and deliver such additional
assignments, bills of sale, deeds and other instruments, as may be reasonably
necessary or proper to carry out the specific provisions of this Agreement,
including transfer to Purchaser of all of Sellers' right, title and interest in
and to the Purchased Assets and any right, title or interest that DCS or any
Affiliate of Sellers or DCS may have in any asset used primarily in the Seller
Business, other than an Excluded Asset. Such efforts and assistance shall be at
the cost of the requesting party.

                  (b)  Anything in this Agreement to the contrary
notwithstanding, neither of the Sellers are obligated to sell, assign, transfer
or convey to Purchaser any of their rights and obligations in and to any
Interest without first obtaining all necessary approvals, consents or waivers.
To the extent any Required Consents have not been obtained by Sellers as of the
Closing and Purchaser elects to proceed with the Closing, Sellers shall, for a
period equal to the shorter of twelve months after the Closing, or the remaining
term of such Interest, (i) except with regard to cell site leases or licenses,
use all commercially reasonable efforts to obtain the consent of any such third
party; (ii) cooperate with Purchaser in any reasonable and lawful arrangements
designed to provide the benefits (including the payment to Purchaser of any
monies received by Sellers in connection therewith and including cooperation
with Purchaser's efforts to obtain the consent of the third party to any such
cell site lease or license regarding the assignment of such cell site lease or
license to Purchaser) of such Interest to Purchaser so long as Purchaser
performs all obligations with respect to the Interest (and the payment of all
expenses in connection therewith); and (iii) enforce, at the request of
Purchaser and at the expense and for the account of Purchaser, any rights of
Sellers arising from such Interest against such issuer thereof or the other
party or parties thereto (including the right to elect to terminate any such
Interest in accordance with the terms thereof upon the request of Purchaser);
provided, however, that none of Purchaser or Sellers shall be obligated to pay
any consideration or other sums therefor (except for filing fees and other
ordinary administrative charges and except as set forth above) to the third
party from whom such approval, consent or waiver is requested.

                  (c)  In the event that at any time between the date hereof and
the first anniversary of the Closing Date Purchaser becomes aware of the
existence of any Contract that was not identified on SCHEDULE 7.06(a) in breach
of the provisions of Section 7.06(a) (an "UNDISCLOSED CONTRACT"), Purchaser may
elect to have such Undisclosed Contract included as

                                      -40-
<Page>

an "Assumed Contract" for all purposes of this Agreement by giving written
notice of such election (an "INCLUSION NOTICE") to Sellers within 90 days after
Purchaser has actual knowledge of the existence of such Undisclosed Contract;
provided, however, that if at least seven (7) days prior to Closing, Sellers
give Purchaser written notice of any Undisclosed Contract of which Sellers have
become aware after the date hereof and deliver a copy of such Undisclosed
Contract to Purchasers, then by the earlier of (x) fifteen (15) days after
Purchaser's receipt of such notice (and the copy of such Undisclosed Contract)
or (y) two (2) days before Closing, Purchaser shall deliver to Sellers an
Inclusion Notice or written confirmation that it has elected not to have such
Undisclosed Contract included as an Assumed Contract.

                       If an Inclusion Notice is given before the Closing, then
SCHEDULE 7.06(A) shall be deemed to be updated to include the Undisclosed
Contract identified in the Inclusion Notice. In addition, SCHEDULE 7.09 shall be
deemed to be updated if necessary to include as a Required Notice or a Required
Consent hereunder any notice or consent required in connection with the
assignment of such Undisclosed Contract. Such updates shall be deemed not to
modify Sellers' representations and warranties hereunder for purposes of Article
XIII hereof.

                       If an Inclusion Notice is given after the Closing, then
Sellers (or, if appropriate, their Affiliate) and Purchaser shall make, execute
and deliver an instrument of transfer, in form and substance reasonably
satisfactory to both parties, pursuant to which Sellers (or their Affiliate)
shall assign their respective rights under such Undisclosed Contract to
Purchaser and Purchaser shall assume certain liabilities thereunder to the same
extent as such rights and liabilities would have been assigned and assumed if
such Undisclosed Contract had been an Assumed Contract on the Closing Date.
Prior to the execution of such instrument of transfer, Sellers shall give any
advance notice required to assign such Undisclosed Contract. Notwithstanding the
foregoing, if a consent is required in connection with such assignment, then
until such time (if any) as such consent is obtained and such instrument of
transfer can be executed, the provisions of Section 18.01(b) shall be
applicable; provided, however, that "twelve months after the Closing" shall be
replaced by "twelve months after the date of the Inclusion Notice."

         SECTION 18.02. NOTICES. All notices and other communications required
or permitted to be given hereunder shall be in writing and shall be deemed to
have been duly given if delivered, sent by telecopier, recognized overnight

costs, including the fees of any corporate or FCC attorney retained by it,
incurred in connection with the preparation of this Agreement and the
consummation of the transactions contemplated hereby; provided that Purchaser
shall bear the expense of all FCC, Hart-Scott-Rodino Act (if applicable) and
other governmental filing fees.

         SECTION 18.04. TRANSFER TAXES. Purchaser on the one hand and Sellers on
the other hand shall bear equally the expense of all use, sales, transfer and
other similar transaction taxes, if any, which are imposed solely and directly
by reason of the sale and delivery of the Purchased Assets from Sellers to
Purchaser under this Agreement. Notwithstanding anything else to the contrary
set forth in this Section 18.04, Purchaser shall in no event be responsible in
any manner for the payment of any taxes on any gross or net income, gross or net
receipts or gain which Sellers or

                                      -42-
<Page>

any Regarded Entity may realize as a result of the sale of the Purchased Assets
or otherwise related to the transactions contemplated by this Agreement.

         SECTION 18.05. COLLECTION PROCEDURES. From and after the Closing,
Purchaser shall have the right and authority, at its expense, to collect for its

any such items.

         SECTION 18.06. GOVERNING LAW. This Agreement shall be governed by and
construed in accordance with the laws of the State of New York (without
application of principles of conflicts of law). In connection with any
controversy arising out of or related to this Agreement, Sellers and Purchaser
hereby irrevocably consent to the jurisdiction of the United States District
Court for the District of New York, if a basis for federal court jurisdiction is
present, and, otherwise, in the state courts of the State of New York. Sellers
and Purchaser each irrevocably consents to service of process out of the
aforementioned courts and waives any objection which it may now or hereafter
have to the laying of venue of any action or proceeding arising out of or in
connection with this Agreement brought in the aforementioned courts.

         SECTION 18.07. ASSIGNMENT. Neither this Agreement nor any of the

into in connection with this transaction shall be binding upon and inure to the
benefit of the parties hereto, their successors and permitted assigns.

         SECTION 18.09. AMENDMENTS; WAIVERS. No alteration, modification or
change of this Agreement shall be valid except by an agreement in writing
executed by the parties hereto. Except as otherwise expressly set forth herein,
no failure or delay by any party hereto in exercising any right, power or
privilege hereunder (and no course of dealing between or among any of the
parties) shall operate as a waiver of any such right, power or privilege. No
waiver of any default on any one occasion shall constitute a waiver of any
subsequent or other default. No single or partial exercise of any such right,
power or privilege shall preclude the further or full exercise thereof.

         SECTION 18.10. ENTIRE AGREEMENT. Except for the NDA, this Agreement
merges all previous negotiations and agreements between the parties hereto,
either verbal or written, and constitutes the entire agreement and understanding
between the parties with respect to the subject matter of this Agreement.

         SECTION 18.11. COUNTERPARTS. This Agreement may be executed in one or
more counterparts, each of which when so executed shall be an original, but all
of which together shall constitute one agreement. Facsimile signatures shall be
deemed original signatures.

         SECTION 18.12. SEVERABILITY. If any provision of this Agreement or the
application thereof to any person or circumstance shall be invalid or
unenforceable to any extent, the remainder of

                                      -43-
<Page>

this Agreement and the application of such provision to other persons or
circumstances shall not be affected thereby and shall be enforced to the
greatest extent permitted by law, but only as long as the continued validity,
legality and enforceability of such provision or application does not materially
(a) alter the terms of this Agreement, (b) diminish the benefits of this
Agreement or (c) increase the burdens of this Agreement, for any person.

         SECTION 18.13. SECTION HEADINGS. The section headings contained in this
Agreement are solely for the purpose of reference, are not part of the agreement
of the parties and shall not in any way affect the meaning or interpretation of
this Agreement.

         SECTION 18.14. INTERPRETATION. As both parties have participated in the
drafting of this Agreement, any ambiguity shall not be construed against either
party as the drafter. Unless the context of this Agreement clearly requires
otherwise, (a) "or" has the inclusive meaning frequently identified with the
phrase "and/or," (b) "including" has the inclusive meaning frequently identified
with the phrase "including, but not limited to" and (c) references to "hereof,"
"hereunder" or "herein" or words of similar import relate to this Agreement.

         SECTION 18.15. FURTHER ASSURANCES. For a period of six (6) months after
Closing, each Seller agrees to, and shall cause DCS to, provide to Purchaser
from time to time any information that such Seller or DCS possesses with respect
to the operation of the Purchased Assets prior to the Closing which the
Purchaser reasonably requests in the future in connection with the Purchaser's
financing efforts now or in the future or in connection with any FCC or other
regulatory filing.

         SECTION 18.16. THIRD PARTIES. Nothing herein, expressed or implied, is
intended to or shall confer on any person other than the parties hereto any
rights, remedies, obligations or liabilities under or by reason of this
Agreement.

         SECTION 18.17. REMEDIES. The parties acknowledge and agree that the
material Purchased Assets, including the FCC Authorizations, are unique and that
remedies at law, including monetary damages, will be inadequate in the event of
a breach by Sellers in the performance of their obligations under this
Agreement. Accordingly, the parties agree that in the event of any such breach
by Sellers prior to the Closing, Purchaser shall be entitled, among other
remedies, to a decree of specific performance.

         SECTION 18.18. CERTAIN DEFINED TERMS. For purposes of this Agreement
(including the Schedules hereto) the terms defined in this Agreement shall have
the respective meanings specified herein, and, in addition, the following terms
shall have the following meanings:

         "Affiliate" means, as to any Person, any other Person which, directly
or indirectly, is in control of, is controlled by, or is under common control
with, such Person. The term "CONTROL" (including, with correlative meanings, the
terms "CONTROLLED BY" and "UNDER COMMON CONTROL WITH"), as applied to any

SECTION 2. GRANT OF DISTRIBUTION RIGHTS

     2.1 APPOINTMENT. Subject to the rights retained by BTI with respect to
PRODUCT under this AGREEMENT, BTI hereby appoints DISTRIBUTOR and its AFFILIATES
as the exclusive distributor and marketer of DISPOSABLE PRODUCTS alone and not
in combination with other products as well as EQUIPMENT for use with DISPOSABLE
PRODUCTS in the FIELD in the TERRITORY. All rights not expressly granted herein
are expressly reserved by BTI. The distribution rights granted hereunder shall
be non-transferable.

          (a) DISTRIBUTOR'S sole compensation under this Agreement shall be the
     profit it may realize from the resale of the PRODUCTS. If a customer in the
     TERRITORY is required by law to receive PRODUCTS directly from the
     manufacturer, DISTRIBUTOR may request that BTI invoice and ship PRODUCTS
     directly to such customer and BTI will do so if DISTRIBUTOR is not
     otherwise in breach of its obligations hereunder. In that event BTI shall
     pay to DISTRIBUTOR a commission of [**] of the [**] received by BTI for
     DISPOSABLE PRODUCTS, [**]; provided however if the customer in question
     fails to pay BTI for the PRODUCTS shipped when such payment is due, then
     DISTRIBUTOR will make such payment after deduction for the commission set
     forth above. DISTRIBUTOR waives any termination limitations or privileges
     including, but not limited to, compensation which might be afforded by law
     in any jurisdiction which deems such a commission to create a protected
     commercial agency relationship.

          (b) DISTRIBUTOR shall be fully responsible for the acts and conduct of
     its employees and its AFFILIATES and SUBDISTRIBUTORS and shall indemnify
     and hold BTI harmless from all claims, liabilities and damages arising out
     of any activities or conduct of such entities which are in breach of this
     Agreement as set forth in Section 11 of this Agreement.

                                       5

<PAGE>

          (c) DISTRIBUTOR shall have no authority to enter into any contracts or
     binding commitments, or to alter any of BTI's warranties, in BTI's name or
     on behalf of BTI. DISTRIBUTOR shall not sign BTI's name to any commercial
     paper or contract or other document.

          (d) DISTRIBUTOR acknowledges that the name and reputation of BTI and
     of the PRODUCTS constitute valuable assets of BTI and shall use its best
     efforts to maintain and enhance the reputation and acceptance of BTI's name
     and the PRODUCTS in dealing with THIRD PARTIES.

          (e) BTI will advise DISTRIBUTOR of inquiries which BTI receives from
     potential customers for the PRODUCTS within the TERRITORY. DISTRIBUTOR
     agrees not to advertise or otherwise seek customers for the PRODUCTS or to
     sell PRODUCTS or otherwise place PRODUCTS with an END USER outside the
     TERRITORY without BTI's prior written consent, and shall not establish any
     branch or maintain any distribution facility for purposes of promoting or
     facilitating sale of the PRODUCTS outside the TERRITORY except as permitted
     by this Agreement. Nevertheless, DISTRIBUTOR will advise BTI of inquiries
     which DISTRIBUTOR receives from potential customers for the PRODUCTS
     outside the TERRITORY.

          (f) In the event any person or entity to whom DISTRIBUTOR sells
     PRODUCT attempts to resell such PRODUCT outside the TERRITORY, then at the
     request of BTI, DISTRIBUTOR shall take appropriate action to attempt to
     prevent such resales of PRODUCT.

     2.2 COMPETITIVE PRODUCTS. During the term of this AGREEMENT, DISTRIBUTOR
agrees that DISTRIBUTOR will not develop or manufacture for, or clinically test,
market or distribute in, any country of the TERRITORY in which it at that time
retains distribution rights under this AGREEMENT any product(s) or combinations
thereof which is/are competitive with the PRODUCT. This restriction shall not
apply to products for use in the treatment of inflammatory conditions such as
sepsis, shock, multiple organ failure or post-surgical complications; or to stem
cells used to produce tissue cells such as renal, hepatocyte and islets.

                                       6

<PAGE>

Notwithstanding the foregoing this provision shall only be applicable in the EU
for the first five years of this AGREEMENT; provided, however, that in the event
that DISTRIBUTOR elects to market or distribute competitive products in the EU
as set forth above after the applicable five year period, DISTRIBUTOR'S
appointment under Section 2.1(a) in the EU shall become non-exclusive for the
remainder of the term of this AGREEMENT.

     2.3 LIMITATIONS ON DISTRIBUTOR.

          (a) DISTRIBUTOR agrees that DISTRIBUTOR (I) will sell and distribute
     PRODUCT only in countries of the TERRITORY for which DISTRIBUTOR retains
     distribution rights under this AGREEMENT; and (II) will sell PRODUCT in the
     TERRITORY only under the TRADEMARK.

          (b) DISTRIBUTOR agrees to distribute PRODUCT only in accordance with
     the terms, conditions and purposes of this AGREEMENT.

     2.4 SUBDISTRIBUTORS. DISTRIBUTOR intends to sell PRODUCT through its
AFFILIATES in countries where DISTRIBUTOR has AFFILIATES in the TERRITORY.
DISTRIBUTOR is authorized to sell product in the TERRITORY through existing and
new SUBDISTRIBUTORS who sell a broad line of DISTRIBUTOR'S products; provided
that DISTRIBUTOR may not sell through SUBDISTRIBUTORS who sell only the BTI line
of PRODUCTS without the written consent of BTI, which shall not be unreasonably
withheld; and provided further that the terms agreed upon with such
SUBDISTRIBUTOR shall also be subject to the approval of BTI and the terms under
which all other SUBDISTRIBUTORS sell BTI PRODUCTS shall be provided to BTI. Any
additional costs associated with the use of SUBDISTRIBUTORS will be borne by
DISTRIBUTOR. DISTRIBUTOR agrees that during the term of this AGREEMENT sales to
SUBDISTRIBUTORS shall amount to no more than [**] percent of total sales of
PRODUCTS made by DISTRIBUTOR. DISTRIBUTOR also agrees that its discount schedule
to SUBDISTRIBUTORS will not unfairly favor DISTRIBUTOR's products over the
PRODUCTS.

     2.5 OTHER DISTRIBUTOR DUTIES. DISTRIBUTOR shall have the following
additional duties:

                                       7

     obtain necessary government approvals (other than the CE mark) to sell
     PRODUCTS throughout the TERRITORY and thereafter to market and sell the

     including arranging for and funding MARKETING STUDIES and any necessary
     registration trials for PRODUCTS in the TERRITORY and paying to BTI at
     DISTRIBUTOR's non-creditable cost in accordance with Section 7.2(b) [**]
     the TRANSFER PRICE set forth in this AGREEMENT for PRODUCTS used for such
     trials. DISTRIBUTOR will keep BTI regularly advised concerning its progress
     and activities relative to obtaining necessary government approvals.

          (b) Maintain and utilize such personnel, organization and facilities
     as will be competent and adequate to (1) meet the market demand for sales,
     clinical support, technical support, scientific resources, logistics and
     quality assurance for PRODUCTS throughout the TERRITORY and (2) generate
     market demand for PRODUCTS through diligent advertising and promotion,
     customer awareness and education programs, commissioning and conduct of
     MARKETING STUDIES and necessary registration trials, and securing
     government, private insurance coverage and/or hospital allowance and
     reimbursement, if any for PRODUCT sales throughout the TERRITORY.

          (c) Furnish quarterly reports as set forth in Section 5.3 herein which
     are intended to provide BTI and the JCs with sufficient market information
     to enable BTI to meet its duties as a manufacturer and developer of medical
     device products under the Medical Device Directives. It is understood that
     BTI has no control over final prices charged by DISTRIBUTOR.

          (d) Not modify or alter the PRODUCTS or labeling in any way without
     the prior written approval of BTI.

          (e) Provide full traceability of the PRODUCTS to its customers by
     PRODUCT code number and by PRODUCT serial number or PRODUCT lot number as
     appropriate to each PRODUCT.

          (f) Provide BTI with information on complaints about the PRODUCTS as
     such information is received. A complaint is considered to be any oral or
     written expression of dissatisfaction with the identity, quality,
     durability, reliability, safety, effectiveness or performance of a PRODUCT.
     Any complaint involving injury or death will be immediately reported to
     BTI.

                                       8

<PAGE>

          (g) Assume full responsibility for its own sales, and all credit risks
     including those sales required to be made by BTI under Section 2.1(a).

          (h) Assume responsibility for development, translation and printing of
     all promotional literature in the TERRITORY, provided that DISTRIBUTOR
     shall provide BTI with timely opportunity to review and approve all such
     promotional literature to ensure consistency with regulatory approvals in
     the TERRITORY and other areas of the world; provided that BTI shall be
     responsible for the development of a standard, global sales brochure for
     each PRODUCT, including text and layout excepting DISTRIBUTOR'S identity,
     with printing, stocking and distribution costs to be borne by DISTRIBUTOR.

          (i) Bear the cost of shipment and installation of PRODUCTS at customer

     manner to BTI, and if BTI determines that such parts are defective, it
     shall credit the EQUIPMENT TRANSFER PRICE for such parts against future
     invoices to DISTRIBUTOR.

          (j) Provide PRODUCT service to customers, excluding parts under
     WARRANTY from BTI, at no cost to such customers for the first twelve (12)

     twenty four (24) hours in all countries of the EU REGION except in Italy
     and Spain where such guarantee shall be within forty eight (48) hours and
     in accordance with DISTRIBUTOR's standard practice in all other parts of
     the TERRITORY.

          (k) Be responsible for the cost of installing any upgrades to customer
     software developed by DISTRIBUTOR or BTI and necessary as determined by the
     JC to enhance functionality or increase versatility of the PRODUCT.

     quality system documents for all PRODUCTS to be sold in the EU and provide
     such technical support and documentation as DISTRIBUTOR may reasonably
     require in order to obtain government approvals to sell the PRODUCTS
     throughout the TERRITORY.

          (e) Have the right, but not the obligation to co-promote the PRODUCTS
     in any REGION of the TERRITORY, including the right, with or without
     DISTRIBUTOR representatives present, to call on customers, exhibit PRODUCTS
     at trade shows, participate in grand rounds and medical conferences, and to
     provide information about the PRODUCTS to potential customers; provided
     that BTI shall inform DISTRIBUTOR in a timely fashion of any resultant
     sales leads or related revenue opportunities for PRODUCTS arising from such
     activities. BTI shall also have the right to participate, at its own
     expense, in any sales calls by DISTRIBUTOR or educational or promotional
     meetings sponsored or controlled by DISTRIBUTOR. Notwithstanding this
     right, the parties shall seek to coordinate such activities of BTI staff
     through the activities of the JC. To the extent that BTI employees in the
     EU are engaged in support activities for PRODUCTS, at any time within
     twelve (12) months from the EFFECTIVE DATE, BTI agrees to discuss with
     DISTRIBUTOR the transfer of such employees to DISTRIBUTOR'S payroll;
     provided that BTI reserves the right to maintain its own employees in the
     TERRITORY during the term of this AGREEMENT.

          (f) Nothing herein shall be deemed to prevent BTI from selling any
     other products in the TERRITORY, including any products related to high
     density microparticle technology which are not listed in Exhibit A, as
     amended from time to time by mutual

                                       10

     combination with other products and products similar to or substantially
     identical to the DISPOSABLE PRODUCTS included in Exhibit A but which are
     indicated for use or sale in combination with other therapeutic products
     are to be reserved for the benefit of BTI.

          (g) Provide DISTRIBUTOR'S service personnel with reasonable technical
     training for the proper use and maintenance of PRODUCTS, at a mutually
     agreed upon location and at mutually agreeable dates. For this purpose BTI
     will pay for the expenses of its personnel and DISTRIBUTOR will pay for all
     other expenses.

          (h) Provide reasonable marketing and sales training and PRODUCT
     information to DISTRIBUTOR'S sales personnel at a mutually agreed upon

     with the formatted text of any standard product information in the English
     language and other advertising material, sales literature and instructions,
     also in the English language, which BTI may have developed and as BTI and
     DISTRIBUTOR deem appropriate to assist DISTRIBUTOR in the promotion, sale
     and service of the PRODUCTS in the TERRITORY. Quantities of such printed
     materials as may be available from BTI may be purchased from BTI at BTI's
     cost. BTI shall also supply with each set of equipment sold by DISTRIBUTOR
     pursuant to this AGREEMENT one copy of an END USER'S manual intended for
     use by the customer, which shall be translated by BTI into up to five
     European languages (the specific languages to be determined at the JCs'
     discretion) and shall also provide DISTRIBUTOR with up to five total sets
     of PRODUCT service materials in English, including appropriate diagrams and
     schematics, to enable DISTRIBUTOR to carry out service at one or more
     centralized facilities. DISTRIBUTOR shall have the right, at its expense,
     to translate any or all of BTI's sales, promotional, PRODUCT use
     instructions or PRODUCT service materials into the various languages
     appropriate to support marketing efforts in the TERRITORY and shall have
     responsibility for ensuring the accuracy of any translation; however BTI
     shall own the rights to the translated materials including, but not
     limited, to any copyrights therein and shall be provided with

                                       11

<PAGE>

     timely opportunity to review and shall have the right to approve all
     marketing and PRODUCT service materials and information developed and used
     by DISTRIBUTOR in the marketing of PRODUCTS. All such rights shall be
     assigned by DISTRIBUTOR to BTI. Unless otherwise agreed, any other
     advertising and promotional expenses shall be paid by DISTRIBUTOR.

          (j) Be responsible for the cost of installing any revisions to
     customer software developed by BTI or DISTRIBUTOR and necessary as
     determined by the JC to improve the reliability (i.e., to assure consistent
     performance to design specifications) of the PRODUCT.

SECTION 3. JOINT COMMITTEE AND OVERSIGHT COMMITTEE

     3.1 JOINT COMMITTEE.

          (a) Promptly after the EFFECTIVE DATE, DISTRIBUTOR and BTI shall
     assemble two (2) Joint Committees, one for a REGION encompassing all
     countries of Europe and a second for a REGION encompassing all other
     countries in the TERRITORY, with each consisting of appropriate personnel
     from both companies to oversee the market development of the PRODUCT in
     those REGIONS, including regulatory approval, clinical development,
     marketing and selling.

          (b) Each JC shall consist of at least four (4) members, two (2) of
     whom shall be appointed by each party hereto. The presence of at least two
     (2) members, one (1) of whom shall have been selected by each party, shall
     constitute a quorum for purposes of action by the JC. Each JC will meet at
     least once each QUARTER and at such other times during the term as shall be
     mutually agreed.

          (c) Decisions of a JC shall be by unanimous approval, with an equal
     number of representatives of both DISTRIBUTOR and BTI voting on the matter;
     provided, however, if a JC cannot reach agreement on a matter, an OVERSIGHT
     COMMITTEE consisting of the two most senior executive officers of each
     party, each with overall responsibility for the PRODUCT, is established and
     the dispute shall be referred to such committee, who shall meet promptly
     and enter into good faith negotiations for a period of time reasonable to
     the circumstances to resolve the dispute.

                                       12

<PAGE>

          (d) In the event the OVERSIGHT COMMITTEE is unable to reach agreement
     on a matter, unless otherwise specifically provided herein the issue shall
     be referred to alternative dispute resolution in accordance with Section 16
     of this AGREEMENT.

     3.2 MARKETING

          (a) By no later than October 1 of each calendar year, DISTRIBUTOR
     shall prepare and submit to each JC proposed detailed marketing plans for
     the applicable REGION and for each country of such REGION, such plans to
     include plans related to the pre-launch, launch, post-launch, and
     associated promotion and sale of PRODUCT. In support of such plan
     DISTRIBUTOR agrees that its commission structure for its sales and
     marketing force will not unfairly favor DISTRIBUTOR's products over the
     PRODUCTS.

          Each JC shall discuss such plan, including any proposed amendments
     and/or additions thereto, and shall decide upon a final plan by November 1
     of the YEAR in which the plan is submitted. The final plan for PRODUCT
     approved by a JC is the MARKET DEVELOPMENT PLAN (MDP) for the following
     YEAR. The approved MDP shall provide for

          o    a national selling effort,

          o    inclusion in DISTRIBUTOR'S annual action plan and in
               DISTRIBUTOR's sales training plan,

          o    the price to END USERS and SUBDISTRIBUTORS as determined solely
               by DISTRIBUTOR for each PRODUCT in each country,

          o    estimates of PRODUCT to be ordered for the YEAR taking into
               account Section 3.3(c),

          o    a budget for selling, marketing and other expenses for the
               PRODUCT for the YEAR,

          o    a staffing plan for all countries in the TERRITORY,

          o    an outline of marketing and detail strategies and tactics,

          o    MARKETING STUDIES, and other post regulatory approval studies, if
               any, for PRODUCT, including a delineation of the roles and
               responsibilities of the field personnel of both parties,

                                       13

<PAGE>

          o    and any other information reasonably requested by a member of the
               applicable JC.

          Once approved, an MDP for a YEAR can be amended only by a decision of
     the applicable JC. Each JC shall make reasonable amendments to the MDP as
     required by a change in circumstances warranting such change, such as, for
     example, unanticipated changes in the market for or availability of
     PRODUCT.

          In addition to approval of the MDP, each JC shall discuss, review and
     monitor marketing of PRODUCT in accordance with the MDP therefor, discuss
     future planning for the marketing of PRODUCT, and coordinate and implement
     any required recall of PRODUCT. It is specifically understood, however,
     that the management and direction of marketing and sales activities and the
     implementation of the MDP shall be managed by DISTRIBUTOR rather than the
     JC.

          (b) Any claim, message or other material part of promotional
     materials, samples, advertising, package inserts, labels and materials for
     training sales representatives with respect to PRODUCT, which has not
     previously been approved by BTI, shall be submitted to BTI for its review
     and approval prior to use by DISTRIBUTOR.

          (c) DISTRIBUTOR shall be responsible for providing advice to BTI and
     the appropriate JC with respect to obtaining regulatory approval, where BTI
     has responsibility for obtaining such approval and with respect to
     regulatory compliance of PRODUCT in the TERRITORY.

     3.3 DISTRIBUTOR COMMERCIALIZATION.

          (a) DISTRIBUTOR shall launch the PRODUCT(S) in each REGION within
     ninety (90) days after such PRODUCT has received CE marking and is made
     available by BTI; provided that DISTRIBUTOR shall launch the B Cell-HDM
     PRODUCTS and accompanying EQUIPMENT in the EU within thirty (30) days of
     the EFFECTIVE DATE of this Agreement. For the avoidance of doubt, in
     countries where regulatory approval and/or pricing approval is required,
     DISTRIBUTOR shall launch PRODUCT within ninety (90) days after such
     regulatory approval and pricing approval (as applicable) is obtained.

          (b) After launch of PRODUCT in a country, DISTRIBUTOR agrees to devote
     its best efforts to market and optimize sales of PRODUCT in such country as
     provided for

                                       14

<PAGE>

     in Section 2.5. In the event BTI believes in good faith that DISTRIBUTOR
     has failed to meet its obligations in this Section 3.3 or in Section 2.5(a)
     in any REGION, BTI shall notify DISTRIBUTOR of the nature of such failure.
     If within sixty (60) days after such notice DISTRIBUTOR has not undertaken
     actions which BTI agrees would cure such failure in a commercially
     reasonable period of time, BTI shall have the option to terminate this
     AGREEMENT with respect to such REGION.

          (c) In addition to DISTRIBUTORS obligations under Section 3.3(b) for
     each REGION, (i) at least six (6) months prior to expected approval of
     PRODUCT for sale in such country, and thereafter (ii) no later than October
     1 prior to the start of each applicable YEAR, the JC for the applicable
     REGION shall meet and agree to the minimum number of units of PRODUCTS to
     be purchased by DISTRIBUTOR for each YEAR in each country of a REGION in
     which registration approval of PRODUCT has been obtained, which shall be
     [**] of the estimate for the YEAR as established in accordance with section
     3.2(a). In the event the JC for a particular REGION is unable to agree on
     the estimate for the YEAR, DISTRIBUTOR shall purchase sufficient units of
     PRODUCTS in the aggregate equivalent to [**] of the sales volume of such
     PRODUCTS sold during the previous YEAR times the following multipliers
     (weighting each PRODUCT based on the YEAR of its approval):

          o    for the second full YEAR after the approval of a PRODUCT, [**];

          o    for the third full YEAR after the approval of a PRODUCT, [**];

          o    thereafter, [**].

          It is understood that there shall be [**]

          (d) In the event that DISTRIBUTOR meets DISTRIBUTOR'S obligations
     under Section 3.3(b) but still does not meet the minimum requirements
     determined in accordance with Section 3.3(c) in a REGION for any [**]
     consecutive YEARS then BTI shall have the option to terminate this
     AGREEMENT with respect to such REGION upon sixty (60) days written notice.

                                       15

SECTION 4. PRODUCT SUPPLY AND DISTRIBUTION

     4.1 PURCHASE OF PRODUCT.

          (a) Subject to Sections 4.2(b) and 4.5, BTI shall sell and DISTRIBUTOR
     shall purchase an amount of PRODUCT equal to DISTRIBUTOR'S requirements in
     the TERRITORY, but in no event shall DISTRIBUTOR purchase less than the
     minimum number of units of PRODUCT provided in Section 3.3. The PRODUCT
     shall be purchased and delivered as finished PRODUCT except in such case as
     BTI shall ship PRODUCT to DISTRIBUTOR prior to QA release with written
     notice to DISTRIBUTOR to quarantine such PRODUCT pending notification of
     final QA release by BTI. In that case, DISTRIBUTOR agrees that it will
     quarantine such PRODUCT and not ship it to END USERS until DISTRIBUTOR
     receives written release from BTI..

          (b) Subject to availability of PRODUCT from BTI, DISTRIBUTOR shall
     maintain sufficient inventories of PRODUCT to enable DISTRIBUTOR to
     effectively satisfy demand for PRODUCT in the TERRITORY.

     4.2 FORECASTS.

          (a) DISTRIBUTOR shall provide BTI and the JC with the best available
     information regarding PRODUCT sales and inventory, as well as a [**]
     by PRODUCT code on the fifteenth business day of each QUARTER with the
     amount specified for each month of the next QUARTER being a binding order
     for that month. This forecast must be approved by the JC and shall be
     consistent with the estimate for the YEAR as determined pursuant to
     Section 3.2(a). The amount specified for each month that is a binding
     order for that month pursuant to this Section 4.2 shall not differ
     (increase or decrease) by more than [**] from the amount specified in the
     rolling forecast for that month that is provided in the QUARTER that
     immediately precedes the rolling forecast for the QUARTER in which the
     order becomes binding. PRODUCT ordered as a binding order for a month shall
     be delivered as soon as reasonably practical; provided that no more than
     [**] of the YEAR'S estimate shall be a binding order for any one month. In
     the event DISTRIBUTOR's order exceeds such amount, BTI will use reasonable
     commercial efforts to accommodate any such order.

                                       16

<PAGE>

          (b) BTI shall not be required to sell or deliver an amount of PRODUCT
     in a month greater than [**] of the binding order for the month or [**] of
     the binding order at such time as DISTRIBUTOR's minimums are calculated in
     accordance with the default formula set forth in Section 3.3(c), but shall
     use reasonable commercial efforts to accommodate any such order.

     4.3 FORM OF ORDER. DISTRIBUTOR'S orders shall be made pursuant to a
purchase order which is in a form mutually acceptable to the parties. BTI shall
use all reasonable efforts to notify DISTRIBUTOR within ten (10) days from
receipt of an order of its ability to fill any amounts of such order in excess
of the quantities that BTI is obligated to supply. No terms contained in any
purchase order, acknowledgment or similar standardized form shall be construed
to amend or modify the terms of this AGREEMENT and in the event of any conflict,
this AGREEMENT shall control unless expressly agreed in writing.

     4.4 PRODUCT REJECTION. If inspection by DISTRIBUTOR reveals that the
PRODUCT supplied by BTI under this AGREEMENT is damaged goods or in any other
regard fails to conform to the applicable SPECIFICATIONS or to the provisions of
Section 4.8 of this AGREEMENT, or in the event such non-conformity is determined
by the END USER promptly after receipt or use by such END USER (except that the
END USER's reason for rejection may not be based on expiration of a PRODUCT if
the PRODUCT had a reasonable remaining shelf life at the time the PRODUCT was
delivered to DISTRIBUTOR), DISTRIBUTOR shall notify BTI no later than fifteen
(15) days after DISTRIBUTOR's receipt of PRODUCT or after notice from such END
USER, as the case may be, and DISTRIBUTOR shall present reasonable evidence to
BTI of such nonconformity or damages. If BTI does not receive such notification
within fifteen (15) days such PRODUCT shall be deemed acceptable and accepted.
BTI shall replace, at no additional expense to DISTRIBUTOR, such non-conforming
PRODUCT with new PRODUCT which does conform within fifteen (15) days after
receipt of DISTRIBUTOR'S notification under this Section. BTI may analyze any
unit of PRODUCT rejected by DISTRIBUTOR for nonconformity and if it is
objectively established that the PRODUCT was conforming, then DISTRIBUTOR shall
be responsible for payment for any such units of PRODUCT. If the parties do not
agree, then the parties shall commission a mutually acceptable qualified
independent

                                       17

<PAGE>

laboratory to resolve the matter. BTI shall give DISTRIBUTOR written
instructions as to how DISTRIBUTOR should dispose of any non-conforming material
at BTI's expense, and such instructions shall comply with all appropriate
governmental requirements.

     4.5 SHORTAGE OF SUPPLY. DISTRIBUTOR acknowledges that BTI is manufacturing
PRODUCT through subcontractors and if at any time BTI becomes unable to supply
worldwide requirements for the PRODUCT, or becomes aware that it will be unable
to supply, it shall promptly notify DISTRIBUTOR in writing. In such event, the
OVERSIGHT COMMITTEE shall immediately meet to address the problem, including
locating alternative suppliers and facilities to increase production and
identifying other actions necessary to resolve the problem. BTI shall take all
reasonable actions to alleviate the shortage and, if applicable, shall
reasonably allocate any PRODUCT during any shortage.

     4.6 SPECIFICATIONS AND REMEDIES. With respect to PRODUCT sold to
DISTRIBUTOR, the PRODUCT will comply with the SPECIFICATIONS and be produced in
accordance with the applicable rules and regulations of the regulatory
authorities in the respective country of the TERRITORY, where the PRODUCT is
produced. DISTRIBUTOR'S sole and exclusive remedy, and BTI's exclusive
liability, for breach of this Section 4.6 and Section 4.4 is recovery of the
price paid for PRODUCT (if BTI is unable to replace said PRODUCT) plus any out
of pocket expenses incurred by DISTRIBUTOR or its AFFILIATE in recovering,
testing and returning or disposing of non-conforming PRODUCT. EXCEPT AS
OTHERWISE EXPRESSLY SET FORTH IN THIS AGREEMENT, BTI MAKES NO REPRESENTATIONS
AND EXTENDS NO WARRANTIES OF ANY KIND, EITHER EXPRESS OR IMPLIED, WITH RESPECT
TO PRODUCTS INCLUDING, BUT NOT LIMITED TO, WARRANTIES OF MERCHANTABILITY, OR
FITNESS FOR A PARTICULAR PURPOSE OR NON-INFRINGEMENT OF THE INTELLECTUAL
PROPERTY RIGHTS OF THIRD PARTIES.

     4.7 TITLE AND RISK OF LOSS. All sales of PRODUCT shall be F.O.B. the
production facility designated by BTI, including BTI's own or contracted
facilities.. Title and risk of loss or damage to PRODUCT shall pass to
DISTRIBUTOR upon delivery of PRODUCT to the carrier designated by the
DISTRIBUTOR. DISTRIBUTOR shall pay the cost and expense of

                                       18

<PAGE>

transportation and insurance directly to the carrier. The cost for all necessary
consular and similar documents and approvals shall be borne by DISTRIBUTOR.
DISTRIBUTOR expressly releases BTI for any loss or damage arising from delays in
delivery of PRODUCTS by the carrier designated by DISTRIBUTOR.

     4.8 PACKAGING AND SHIPPING: PRODUCTS will be packed for shipping in
packaging appropriate to maintain the necessary temperature during shipping
and any anticipated storage period under PRODUCT SPECIFICATIONS. BTI will use
commercially reasonable efforts to ensure that, at the time of delivery to
the carrier, the PRODUCTS will have a remaining shelf life of [**] PRODUCT
life but no less than (i) [**] during the first [**] this AGREEMENT is in
effect; (ii) [**] during the next [**] period; and (iii) [**] thereafter. If
during the first [**] after the EFFECTIVE DATE BTI has shipped PRODUCT with a
shelf life of less than [**] and DISTRIBUTOR is unable to sell such PRODUCT
prior to its expiration, BTI will replace such expired PRODUCT at a price
which equals BTI's actual cost to manufacture.

SECTION 5. PRICE FOR PRODUCTS

     5.1 PRICE.

          (a) BTI shall sell and DISTRIBUTOR shall purchase PRODUCTS at a price
     payable in U.S. dollars equal to the EQUIPMENT TRANSFER PRICE and the
     DISPOSABLE TRANSFER PRICE in effect at the time of the sale.

          (b) Additionally, DISTRIBUTOR shall pay to BTI, on a REGION by REGION
     basis, the difference, if any, between the DISPOSABLE TRANSFER PRICE of
     PRODUCTS and [**] of the NET SALES of such PRODUCTS sold by DISTRIBUTOR
     during each QUARTER.

          After a DISPOSABLE PRODUCT has been commercially available for [**],
     either party may request that the JC approve an adjustment in the TRANSFER
     PRICE of such PRODUCT and thereafter may request an adjustment [**] so
     long as this AGREEMENT remains in effect if the following conditions
     exist.

                                       19

<PAGE>

               (i) BTI may request that the JC approve an increase in the
          DISPOSABLE TRANSFER PRICE and/or the EQUIPMENT TRANSFER PRICE (so long
          as after such increase the DISPOSABLE TRANSFER PRICE of PRODUCTS will
          not be greater than [**] of the NET SALES for such PRODUCTS during the
          previous six (6) month period) if the cost of components for PRODUCTS
          increases by more than [**] from the cost as of the EFFECTIVE DATE or
          the most recent increase in the TRANSFER PRICE for PRODUCTS included
          in Exhibit B.

               (ii) DISTRIBUTOR may request that the JC decrease the DISPOSABLE
          TRANSFER PRICE up to [**] of the then applicable DISPOSABLE TRANSFER
          PRICE for the next twelve (12) month period but DISTRIBUTOR may not
          receive more than [**] price reductions of [**] (as calculated above)
          during the term of this AGREEMENT. To be eligible for any such price
          decrease, DISTRIBUTOR must demonstrate that, based on DISPOSABLE
          PRODUCT NET SALES during the most recent six (6) month period, the
          DISPOSABLE TRANSFER PRICE was greater than [**] of the NET SALES of
          such PRODUCTS to END USERS.

     Upon approval of any request to modify the DISPOSABLE TRANSFER PRICE and/or
     the EQUIPMENT TRANSFER PRICE, Exhibit B shall be amended to include the new
     TRANSFER PRICES for PRODUCTS.

     5.2 PAYMENT FOR PRODUCTS. The portion of the price for PRODUCTS set forth
in Section 5.1(a) shall be due and payable within forty five (45) days of the
later of shipment or BTI's invoice of the PRODUCT. The portion of the price for
PRODUCT set forth in Section 5.1(b) shall be paid within forty-five (45) days
after the QUARTER in which PRODUCT is sold by DISTRIBUTOR or its AFFILIATES or
its or their SUBDISTRIBUTORS. In the event DISTRIBUTOR fails to make any payment
when due, in addition to any other remedies BTI may have, DISTRIBUTOR shall pay
the lesser of one and one-half percent (1 1/2%) interest per month, or the
highest rate permitted by applicablE law. BTI shall not be deemed to be in
breach of this Agreement or any purchase order issued hereunder by failing to
ship PRODUCTS if

                                       20

<PAGE>

DISTRIBUTOR has a past due balance owed to BTI and DISTRIBUTOR shall pay BTI for
any costs incurred in collecting such past due unpaid balance.

     5.3 DELIVERY OF ACCOUNTING.

          (a) Within forty-five (45) days after the end of each CALENDAR
     QUARTER, DISTRIBUTOR shall deliver to BTI a full and accurate written
     accounting with respect to PRODUCT sold in the TERRITORY on a REGION by

          discounts or amortization relative to EQUIPMENT.

               (ii) Gross sales (by country and customer) in the same local

          Section 5.1(a).

               (vii) Calculation of total net compensation payable to BTI under
          Section 5.1(b).

               (viii) Any other information reasonably requested by BTI and in

     5.4 BTI AUDIT RIGHTS. DISTRIBUTOR shall keep, and shall cause its
AFFILIATES and its and their SUBDISTRIBUTORS to keep, complete and accurate
records of the accounting items of 5.3(a)(i) through 5.3(a)(viii), such records
to be in a form required under U.S. Generally Accepted Accounting Principles
(GAAP) (or IAS if applicable), consistently applied. BTI shall have the right at
its expense on reasonable advance notice to examine such records, in Lakewood,
Colorado USA or such other location where such records are maintained in the
usual course of business, through a certified public accountant or other
representative reasonably acceptable to DISTRIBUTOR during regular business
hours during the life of this AGREEMENT and for one (1) year after its
termination; provided, however, that such examination shall not take place more
often than twice a year and shall not cover such records for more than the
preceding three (3) years and provided further that such accountant shall report
to BTI only as to the accuracy of the records and details with respect thereto.
In the event that such inspection reveals that, for the applicable period, the
amounts paid to BTI, pursuant to Sections 5.1(a) and (b) is less than the
amounts that should have been paid to BTI, DISTRIBUTOR shall pay such deficiency
to BTI plus interest as provided in Section 5.2, and if such payments are at
least ten percent (10%) less than the payments that should have been made, then
DISTRIBUTOR shall also pay the reasonable cost of such inspection.

SECTION 6. PAYMENTS

     6.1 U.S. DOLLARS. All sums due under this AGREEMENT shall be payable in
U.S. dollars. Monetary conversion from the currency of a foreign country, in
which PRODUCT is sold, into United States currency shall be calculated as
follows:

          (a) From the EFFECTIVE DATE through December 31, 2001, the actual
     exchange rate as published by Reuters for each month during such period;

          (b) For the YEAR 2002 and each YEAR thereafter, as determined by BTI
     during the final quarter of the previous YEAR, either in accordance with
     the standard method used internally by DISTRIBUTOR for making such
     conversions or the actual exchange rate as published by Reuters for each
     month during the relevant YEAR.

                                       22

     6.2 FEES. DISTRIBUTOR shall:

          (a) Pay to BTI an initial fee of four Million Dollars ($4,000,000) on
     the EFFECTIVE DATE of this Agreement, in consideration of which fees
     DISTRIBUTOR has been granted the rights set forth herein in the TERRITORY.

          (b) At such time as BTI notifies DISTRIBUTOR in writing that any
     DISPOSABLE PRODUCT listed in Exhibit A has been granted the CE Mark and is
     ready for delivery, DISTRIBUTOR shall pay BTI an additional fee of [**] per
     PRODUCT. The parties acknowledge that CE mark approval has been obtained
     for the first such PRODUCT and that the fee set forth herein is payable on
     the EFFECTIVE DATE with respect to such PRODUCT.

          (c) An additional fee of [**] will also be paid by DISTRIBUTOR for
     the BrCa-HDM breast tumor PRODUCT listed in Exhibit A upon any [**]
     for [**] based on [**] from a [**] commitment to diligently develop the
     BrCa-HDM breast tumor PRODUCT.

          (d) In the event that during the term of this AGREEMENT BTI determines
     to develop or release additional products in the FIELD, BTI shall notify
     DISTRIBUTOR and DISTRIBUTOR shall have an option to add such products to
     this AGREEMENT in the TERRITORY upon payment of an additional fee of [**]
     per product line, payable upon exercise of DISTRIBUTOR'S option, and an
     additional fee upon the granting of the CE mark for any such PRODUCT of
     [**] of the cumulative [**] year revenue forecast for such PRODUCTS in the
     TERRITORY (as determined by the JCs in good faith). In the event
     DISTRIBUTOR fails to exercise its option hereunder within sixty (60) days
     after notification by BTI, the option will expire and BTI shall be free to
     offer or grant such rights to a THIRD PARTY on whatever terms it chooses or
     to commercialize such products itself. The additional fee for a new use of
     an antibody used in a DISPOSABLE PRODUCT already listed in Exhibit A shall
     be determined by the parties in good faith at the time BTI determines to
     develop or release a product for such new use. In the event that the number
     of bone marrow transplants for the treatment of breast cancer reach [**]
     in Europe within [**] of the EFFECTIVE DATE of this

                                       23
<PAGE>

     AGREEMENT as determined by the European Bone Marrow Transplant Group
     Registry, adjusted upward to reflect the percentage, as specified by the
     EBMT Registry of non-reporting transplant groups, then DISTRIBUTOR shall
     within thirty (30) days of publication of such determination pay BTI the
     sum of [**]; provided, however, that BTI will refund such payment if BTI
     has not received a CE mark for the breast cancer PRODUCT within [**]
     after the EFFECTIVE DATE.

          (e) All of the sums payable hereunder shall be payable by DISTRIBUTOR
     from its principal place of business in the United States and DISTRIBUTOR
     acknowledges that none of such payments are subject to withholding taxes
     and therefore shall be paid in full when due.

SECTION 7. DEVELOPMENT

     7.1 PRODUCT DEVELOPMENT. During the term of the AGREEMENT, BTI shall use
commercially reasonable efforts to achieve CE mark approval of PRODUCT from the
appropriate agency permitting sale under the Medical Device Directives in the EU
and shall keep the JC reasonably informed of its activities. In the event such
approval is not obtained , the sole and exclusive remedy shall be deletion of
the PRODUCT in question from this AGREEMENT.

     7.2 REGULATORY COST IN THE TERRITORY.

          (a) BTI shall be responsible for the entire cost and expense of
     performing pre-clinical studies and providing quality system documents
     necessary to obtain CE mark approval for PRODUCTS requiring such approval
     from the EC in Europe.

          (b) If the JC decides to conduct any additional post regulatory
     approval studies in the EU or any such study is required for PRODUCT
     registration or reimbursement in a sub-region of the TERRITORY, then on an
     ongoing basis, DISTRIBUTOR shall pay the entire cost and expense of such
     studies. DISTRIBUTOR shall have the right to credit [**] of any amounts
     paid by DISTRIBUTOR under this Section 7.2(b) with respect to PRODUCT for
     a country against the next quarterly payment pursuant to Section 5.1(b)
     and, if not fully credited, then against any amounts due from DISTRIBUTOR
     to

                                       24

<PAGE>

     BTI thereafter. DISTRIBUTOR will provide such PRODUCTS free of charge to
     END USERS for use in the study and will not sell such PRODUCTS directly or
     indirectly.

          (c) Any studies for which BTI has contracted as of the EFFECTIVE DATE
     shall be deemed approved by the JC and subject to DISTRIBUTOR sharing [**]
     the cost of PRODUCT to be used in such studies after the EFFECTIVE
     DATE. DISTRIBUTOR shall manage such studies, but shall not be responsible
     for any other costs or funding associated with such studies.

          (d) If clinical studies are required for CE mark approval in the EU
     due to changes in the laws or regulations of any sub-region, the JC will
     determine in good faith how the costs of such studies should be shared by
     BTI and DISTRIBUTOR.

     7.3 PRICING/REIMBURSEMENT. DISTRIBUTOR will pursue at its cost and expense
pricing approval and/or reimbursement from the appropriate governmental
(national and state and/or local) authorities in any countries where required.
DISTRIBUTOR agrees to keep the JC reasonably informed as to the status of such
applications, approvals and/or denials.

     7.4 BTI ASSISTANCE. BTI shall, at DISTRIBUTOR'S non-creditable expense,
provide any and all assistance reasonably required by DISTRIBUTOR to obtain
regulatory approval of PRODUCT in countries of the TERRITORY.

SECTION 8. PATENT INFRINGEMENT

     8.1 INFRINGEMENT BY PRODUCT.

          (a) In the event either party becomes aware of any potential patent or
     trademark infringement, or in the event of the institution of any suit by a
     THIRD PARTY against DISTRIBUTOR or BTI for patent or trademark infringement
     involving the use, sale, distribution or marketing of PRODUCT that is being
     distributed by DISTRIBUTOR, its AFFILIATES or their SUBDISTRIBUTORS under
     this AGREEMENT anywhere in the TERRITORY, either party shall promptly
     notify the other in writing. With respect to any such action, BTI shall
     bear, and shall hold DISTRIBUTOR harmless from, the costs of

                                       25

<PAGE>

     defense and of any compensatory damages awarded against either of them. BTI
     shall have the sole right to control the defense, settlement and compromise
     of any such action.

          (b) If a court of competent jurisdiction determines that a third party
     has a superior right in the technology relating to the PRODUCTS, or if BTI
     voluntarily abandons its rights as part of a settlement with a third party
     claiming superior rights, BTI will use its best efforts to obtain, at BTI's
     expense, a commercially reasonable license for DISTRIBUTOR to continue to
     sell the PRODUCTS.

     8.2 THIRD PARTY INFRINGEMENT. In the event that BTI or DISTRIBUTOR becomes
aware of actual or threatened infringement of a patent or trademark owned by BTI
anywhere in the TERRITORY related to PRODUCTS, that party shall promptly notify
the other party in writing and actively consult and co-operate in responding to
such event. BTI shall have the first right but not the obligation to bring, at
its own expense, an infringement action against such THIRD PARTY. If BTI does
not commence a particular infringement suit within thirty (30) days of receipt
of a request by DISTRIBUTOR to do so, then DISTRIBUTOR, after notifying BTI in
writing and obtaining BTI's consent, which shall not be unreasonably withheld,
shall be entitled to bring such infringement action at DISTRIBUTOR'S expense and
to include BTI as a nominal party plaintiff. Subject to Section 8.4, the party
conducting such action shall have full control over its conduct. Subject to
Section 8.3 regardless of which party brings such action, the other party hereby
agrees to cooperate reasonably in any such effort at its expense. The party not
bringing the action shall have the right, but not the duty, to participate in
such action at its own expense with its own counsel.

     8.3 RECOVERY. BTI and DISTRIBUTOR shall first recover their respective
actual out-of-pocket expenses (including reasonable attorney fees), or equitable
proportions thereof, associated with any litigation against infringers
undertaken pursuant to Section 8.2 above or settlement thereof from any
resulting recovery made by any party. Any excess amount of such a recovery shall
be shared between DISTRIBUTOR and BTI, with each party receiving in proportion
to its economic interest in the infringed property: [**] to BTI and [**] to
DISTRIBUTOR. In the event that the party not bringing the action is willing to
waive its right to participate in the recovery obtained from the THIRD PARTY,
then the party instituting the

                                       26

<PAGE>

lawsuit shall be responsible for all costs and expenses of the non-participating
party in cooperating with the party instituting the lawsuit.

     8.4 STATUS OF ACTIVITIES AND SETTLEMENT. The parties shall keep one another
informed of the status of their respective activities regarding any litigation
or settlement thereof concerning PRODUCT in the TERRITORY; provided however that
no settlement or consent judgment or other voluntary final disposition of any
suit defended or action brought by a party pursuant to this Section 8 may be
entered into without the consent of the other party if such settlement would
require the other party to be subject to an injunction or to make a monetary
payment or would otherwise adversely affect the other party's rights under this
AGREEMENT. In addition, DISTRIBUTOR shall not have the right to settle or enter
into a consent judgment or a voluntary disposition if it will adversely affect
any patent owned by BTI or BTI's interest therein.

     8.5 ABANDONMENT RIGHTS. BTI, in its sole discretion, may elect to abandon
its rights to patents or trademarks in any country of the TERRITORY without any
liability to DISTRIBUTOR and DISTRIBUTOR'S sales of PRODUCTS in those countries
will continue to be covered under the terms of this AGREEMENT

SECTION 9. OPTIONS

     9.1 UNITED STATES AND CANADA. DISTRIBUTOR shall have an option to
negotiate with BTI to obtain the exclusive right to distribute PRODUCTS in
the United States and/or Canada, which option may be exercised by giving BTI
written notice at any time during the [**] period which commences one (1)
month following the EFFECTIVE DATE. If DISTRIBUTOR provides notice that it
wishes to exercise its option with respect to the United States and/or
Canada, it shall pay BTI at the time it provides such notice a non-refundable
fee of [**] for the United States. The parties will then enter into
negotiations for up to [**] to endeavor to agree upon the terms of a separate
agreement with respect to these rights. In the event an agreement cannot be
reached by the end of the [**] period BTI shall be free to offer such rights
to a THIRD PARTY on such terms as it may determine not more favorable than
those offered to DISTRIBUTOR; provided however that until DISTRIBUTOR'S
option expires BTI

                                       27

<PAGE>

will not offer any such rights to any THIRD PARTY to distribute PRODUCTS in
the United States or Canada. Notwithstanding the foregoing, in the event
DISTRIBUTOR notifies BTI that it wishes to exercise its option hereunder but
does not pay the fee as aforesaid BTI will enter into negotiations with
DISTRIBUTOR on a non-exclusive basis for the earlier of [**] following
commencement of negotiations, or until BTI in its sole discretion determines
to grant such rights to a THIRD PARTY.

     9.2 JAPAN. In the event BTI determines it is ready to commence
discussions with THIRD PARTIES relative to commercialization of PRODUCTS for
sales in Japan, BTI shall first notify DISTRIBUTOR of the opportunity to
obtain such rights under a separate agreement. In the event DISTRIBUTOR
wishes to obtain such rights DISTRIBUTOR shall notify BTI within thirty(30)
days of such notification by BTI. In the event DISTRIBUTOR so notifies BTI,
the parties shall negotiate in good faith for [**] with respect to an
agreement for such rights. If no agreement is reached within that time BTI
shall be free to offer such rights to a THIRD PARTY on whatever terms it
deems appropriate.

SECTION 10. TRADEMARK

     10.1 TRADEMARK SELECTION. BTI and DISTRIBUTOR shall jointly select a
trademark under which PRODUCT will be distributed by DISTRIBUTOR. If BTI and
DISTRIBUTOR cannot agree on such a trademark, then BTI shall have the right to
select such trademark. The trademark selected jointly or by BTI is the
TRADEMARK.

     10.2 BTI OWNERSHIP OF TRADEMARK. BTI shall own all right, title and
interest in and to the TRADEMARK, and DISTRIBUTOR acknowledges and agrees that
any and all uses of the TRADEMARK by DISTRIBUTOR, its AFFILIATES and its and
their SUBDISTRIBUTORS shall be for and inure to the benefit of BTI. The costs of
registration and maintenance shall be borne by BTI.

     10.3 PROMOTIONAL MATERIALS. DISTRIBUTOR shall submit representative samples
of all promotional materials using the TRADEMARK(S) to BTI for BTI's reasonable
approval prior

                                       28

<PAGE>

to their first use and prior to any subsequent significant or substantial change
or addition to such promotional materials provided that if BTI has not responded
within four (4) weeks after such submissions, BTI's approval will be deemed to
have been received. DISTRIBUTOR shall acknowledge BTI's interest in the
TRADEMARK in all materials that use the TRADEMARK.

     10.4 USE OF TRADEMARK.

          (a) DISTRIBUTOR agrees that it will use the TRADEMARK only on PRODUCT
     and related promotional materials distributed by DISTRIBUTOR in accordance
     with the terms and conditions of this Agreement.

          (b) DISTRIBUTOR agrees that it will not use the TRADEMARK in any
     manner that adversely affects the TRADEMARK and/or BTI's interest therein.

          (c) BTI may conduct an audit or inspection of DISTRIBUTOR'S use of the
     TRADEMARK to determine DISTRIBUTOR'S compliance with this provision and
     DISTRIBUTOR will cooperate with BTI in this regard.

          (d) Use of the TRADEMARK on any printed material shall always be
     accompanied by an appropriate legend agreed to by BTI, denoting BTI as the
     owner of the TRADEMARK.

          (e) The parties will cooperate with each other to register
     DISTRIBUTOR'S use of the TRADEMARK in any country where required.

          (f) DISTRIBUTOR will cease use of the TRADEMARK in all countries upon
     termination of this AGREEMENT; or in any country in which DISTRIBUTOR'S
     rights under this AGREEMENT have been terminated.

          (g) DISTRIBUTOR will not register any domain names which incorporate
     the TRADEMARK or marks that are confusingly similar to the TRADEMARK or any
     part of BTI's tradename.

SECTION 11. INDEMNITY AND INSURANCE

     11.1 INDEMNIFICATION BY DISTRIBUTOR. Notwithstanding any other provision of
this Agreement, DISTRIBUTOR shall defend, indemnify and hold harmless BTI, its
officers, directors, shareholders, employees, agents, successors and assigns (a
"BTI Indemnified Party") from any loss, damage, or liability, including
reasonable attorney's fees, resulting from any THIRD PARTY claim, complaint,
suit, proceeding or cause of action against any of them of any nature
(individually and collectively "BTI Loss(es)"), resulting from or arising out of
(i) the negligence or willful misconduct of DISTRIBUTOR, its AFFILIATES, or its
or their SUBDISTRIBUTORS (as to SUBDISTRIBUTORS as such conduct relates to their
performance under this Agreement) or any of their respective officers,
directors, employees or agents (individually and collectively a "DISTRIBUTOR
ACTOR"), or (ii) any violation of approved labeling by a DISTRIBUTOR ACTOR, or
(iii) the marketing of the PRODUCT, or any other action of a DISTRIBUTOR ACTOR,
with respect to PRODUCT in each case which is not in compliance with applicable
law, rules or regulation, or (iv) from any claim, warranty or representation of
a DISTRIBUTOR ACTOR with respect to PRODUCT that is inconsistent with approved
labeling, or (v) any damages or changes to the PRODUCT made by a DISTRIBUTOR
ACTOR.

     11.2 INDEMNIFICATION BY BTI. Notwithstanding any other provision of this
Agreement, BTI shall defend, indemnify and hold harmless DISTRIBUTOR, or its
AFFILIATES and their respective officers, directors, shareholders, employees,
successors and assigns ("DISTRIBUTOR INDEMNIFIED PARTY") from any THIRD PARTY
claim, complaint, suit, proceeding or cause of action against any of them of any
nature (individually and collectively "DISTRIBUTOR Loss(es)"), resulting from or
arising out of (i) the negligence or willful misconduct of BTI or its
AFFILIATES, or its subcontractors (as to subcontractors as such conduct relates
to the PRODUCT), or their respective officers, directors, employees or agents
(individually and collectively a "BTI ACTOR"); or (ii) DISTRIBUTOR Losses that
are determined to result from a PRODUCT not conforming to the SPECIFICATIONS for
the PRODUCT or (iii) DISTRIBUTOR Losses that are determined to result from
manufacturing defect with respect to PRODUCT provided to DISTRIBUTOR by BTI,
which manufacturing defect was not known to a

                                       30

<PAGE>

DISTRIBUTOR INDEMNIFIED PARTY; or (iv) any action of a BTI ACTOR, with respect
to PRODUCT which is not in compliance with applicable law, rules or regulation.

     11.3 PROCEDURE FOR INDEMNIFICATION. A person or entity that intends to
claim indemnification under this Section 11 (the "Indemnitee") shall promptly
notify the other party (the "Indemnitor") of any loss in respect of which the
Indemnitee intends to claim such indemnification. The indemnity agreement in
this Section 11 shall not apply to amounts paid in settlement of any loss,
claim, damage, liability or action if such settlement is effected without the
consent of the Indemnitor, which consent shall not be withheld or delayed
unreasonably. The failure to deliver notice to the Indemnitor within a
reasonable time after the commencement of any such action, only if prejudicial
to its ability to defend such action, shall relieve such Indemnitor of any
liability to the Indemnitee under this Section 11, but the omission so to
deliver notice to the Indemnitor will not relieve it of any liability that it
may have to any Indemnitee otherwise than under this Section 11. The Indemnitee
under this Section 11, its employees and agents, shall cooperate fully with the
Indemnitor and its legal representatives in the investigations of any action,
claim or liability covered by this indemnification. An Indemnitee shall have the
right to participate in the defense of any such claim, complaint, suit,
proceeding or cause of action utilizing attorneys of its choice, at its own
expense, provided, however, that, the Indemnitor shall have full authority and
control to handle any such claim, complaint, suit, proceeding or cause of
action, including any settlement or other disposition thereof, for which the
Indemnitor agrees to provide full indemnification under this Section 11.

     11.4 INSURANCE.

          (a) Each of the Parties shall maintain in effect at all times during
     the term of this Agreement insurance with a company with an A.M. Best
     rating of B+XII or better. Such insurance shall include, without
     limitation, the following: (i) workers' compensation coverage in statutory
     amounts and in compliance with the laws and regulations where the party
     conducts its business; (ii) employer's liability coverage with minimum
     limits of $1 million bodily injury for each accident, $1 million bodily
     injury disease aggregate, and $1 million bodily injury by disease for each
     employee; (iii) comprehensive general liability ("CGL") with minimum limits
     of $5 million combined single limits per occurrence for

                                       31

<PAGE>

     bodily injury and property damage and $5.0 million general aggregate
     written on an occurrence basis. The CGL insurance shall contain, but not be
     limited to, personal injury liability and contractual liability, which
     insures the party's indemnification obligations under this Agreement. Each
     Party shall be designated as an additional insured to the CGL insurance of
     the other Party.

          (b) Each of the Parties shall maintain a minimum of $5 million per
     claim and in the aggregate of product liability and completed operations
     insurance, which will be on an occurrence basis, and if such policy is
     claims-made, shall be maintained for a minimum of three (3) years following
     the expiration or any termination of this AGREEMENT; or, in the
     alternative, a tail policy purchased for such three year period.

          (c) All insurance maintained by either Party shall be primary coverage
     without any right of contribution from the other Party. On or before the
     first use of the PRODUCT in humans, and thereafter upon request by the
     other Party, each Party shall provide the other Party with certificates
     which evidence the insurance required to be maintained under this
     Agreement. The certificates of insurance required hereunder shall state
     that the other Party shall be provided a minimum of thirty (30) calendar
     days' prior written notice of any proposed cancellation, material change in
     coverage, or expiration without renewal. BTI shall also maintain in its
     files evidence of all contractors' and subcontractors' insurance coverage
     and shall provide proof of such coverage to DISTRIBUTOR upon DISTRIBUTOR'S
     request. The terms of this Section shall not be deemed to limit the
     liability of either party hereunder.

     11.5 LIMIT OF LIABILITY. Notwithstanding anything in this AGREEMENT to the
contrary BTI shall have no liability for indirect, consequential or special
damages, including, but not limited to, damages for lost profits and BTI's
liability for any and all losses or damages to DISTRIBUTOR resulting from
defective PRODUCTS or from any other cause shall be limited to the proceeds from
liability insurance maintained by BTI or its parent corporation plus an amount
up to the total of all fees and PRODUCT costs paid by DISTRIBUTOR to BTI under
this AGREEMENT.

SECTION 12. ADVERSE EXPERIENCES, RECALLS AND CONFIDENTIALITY

     12.1 ADVERSE EXPERIENCES.

          (a) With respect to any adverse experiences relating to the PRODUCT,
     the parties shall report to each other and the appropriate regulatory
     authorities in the countries in which the PRODUCT is being developed or
     commercialized, in accordance with the appropriate laws and regulations of
     the relevant countries and authorities. Such reporting activities within
     the TERRITORY shall be coordinated by the JC. If the manufacturer of a
     PRODUCT is obligated in any jurisdiction to be the sole reporter of adverse
     events, including MDRs and vigilance reports, then BTI shall be solely
     responsible for such filing.

          (b) Promptly following the execution of this AGREEMENT the parties
     agree to (i) enter into a standard operating procedure to govern
     collection, investigation and reporting to regulatory authorities of
     PRODUCT-related adverse experience reports, quality reports, and complaint
     reports, and (ii) establish criteria for Medical Device Reporting (MDR)
     such that all of the parties can comply with their legal obligations
     worldwide. The standard operating procedure and/or reporting criteria will
     be promptly amended as changes in legal obligations require.

     12.2 AGENCY ACTION. The parties agree to notify each other as soon as
possible of any information received by a party regarding any threatened or
pending action by a regulatory authority which may affect the safety or efficacy
claims of PRODUCT or the continued marketing of such PRODUCT.

     12.3 RECALLS.

          (a) If any governmental authority having jurisdiction requires or
     reasonably requests any party to recall any PRODUCT due to a defect in the
     manufacture, processing, packaging or labeling of PRODUCT or for any other
     reason whatsoever, such party shall immediately notify in writing the other
     party to this AGREEMENT. BTI shall also have the right to initiate this
     recall procedure absent a request from a governmental authority after
     consultation with the DISTRIBUTOR. All costs of any recall shall be borne
     by BTI to the extent such recall is the result of the negligence or willful
     misconduct of BTI or

                                       33

     manufacturer or is based on nonconformity with the SPECIFICATIONS for the
     PRODUCT and/or a defect, error or omission in regard to the manufacture of
     the PRODUCT. Costs of any recall shall be borne by DISTRIBUTOR to the
     extent such recall is the result of the negligence or willful misconduct of
     DISTRIBUTOR or SUBDISTRIBUTOR or is based on the storage, handling or
     promotional activities controlled by DISTRIBUTOR OR SUBDISTRIBUTOR.

          (b) Prior to commencing any recall, DISTRIBUTOR shall review with BTI
     the proposed manner in which the recall is to be carried out. DISTRIBUTOR
     agrees to follow any reasonable advice of BTI as to the manner of
     completing the recall, so long as such advice is not inconsistent with the
     requirements of the governmental authority involved, if any.

          DISTRIBUTOR shall carry out the recall in the manner agreed upon
     between BTI and DISTRIBUTOR in as expeditious a manner as possible and in
     such a way as to cause the least disruption to the sales of the PRODUCT and
     to preserve the goodwill and reputation attached to the PRODUCT and to the
     names of DISTRIBUTOR and BTI.

          PARTY having a lawful right to make such disclosure, and who is not
          under an obligation of confidentiality to the disclosing party or is
          developed by the receiving party independently of the disclosure of
          the disclosing party;

               (iv) is required by law or BONA FIDE legal process to be

          companies), customers, healthcare professionals, consumers or
          regulatory agencies as part of its routine advertising or promotional
          activities or medical education, professional services, adverse event
          investigation and reporting, or PRODUCT quality or complaint

          to market and sell PRODUCT in their respective countries of the
          TERRITORY as permitted by this AGREEMENT (provided that such
          AFFILIATES and SUBDISTRIBUTORS agree to be bound by the
          confidentiality obligations set forth in this Section).

          (b) Upon termination or expiration of this AGREEMENT, each party shall
     return to the other party all tangible forms of Confidential Information
     furnished by the other party, including all copies thereof and all
     memoranda of oral disclosure, except that each party may retain one copy in
     its files to ensure compliance with any legal obligations.

          (c) This Section shall survive until the tenth anniversary of the
     termination or expiration of this AGREEMENT.

     12.5 TERMS OF AGREEMENT. No public announcement or other public disclosure
concerning the terms of this AGREEMENT shall be made, either directly or
indirectly, by any party to this AGREEMENT, except in connection with a merger
or acquisition of a party or as

                                       35

<PAGE>

first obtaining the written approval of the other party and agreement upon the
nature and text of such announcement or disclosure. The party desiring to make
any such public announcement or other disclosure shall provide the other party
with a copy of the proposed announcement or disclosure for review and comment in
reasonably sufficient time prior to public release. Each party agrees that it

or regulatory agencies, including requests for confidential treatment of
proprietary information of either party included in any such disclosure. In
addition, each party agrees not to disclose the terms of this AGREEMENT to THIRD
PARTIES, except to professional advisors and financing sources in connection
with a due diligence investigation by a potential lender, investor or purchaser
of the BTI business, or under conditions that reasonably protect the
confidentiality thereof. The parties will mutually agree upon the contents of a
press release (and accompanying Q&:A) which may be issued upon the Effective
Date, and thereafter the parties may publicly disclose information contained in
such press release or Q&A without further approvals.

submission by a THIRD PARTY or customer for written or oral publication any
manuscript, abstract or the like which includes data or other information

SECTION 14. TERM AND TERMINATION

     14.1 EXPIRATION. Unless otherwise specified in this AGREEMENT, upon written
notice from one party to the other at least ninety (90) days prior to the
specified date, the rights and obligations of the parties under this AGREEMENT
shall terminate seven (7) years from the EFFECTIVE DATE of this Agreement. Six
(6) months prior to the expiration of this AGREEMENT and for thirty (30) days
thereafter, either party may request that this AGREEMENT be extended. If such a
request is made by the DISTRIBUTOR, DISTRIBUTOR will provide BTI with a proposal
setting forth the terms upon which the AGREEMENT should be extended and in
either case, the parties will negotiate with respect to such extension to
determine if such an extension can be agreed upon and the terms for such an
extension all of which must be mutually agreed upon.

     14.2 BREACH. This AGREEMENT may be terminated by either party if: (i) the
other party fails to observe, perform or otherwise breaches any of its material
covenants, agreements or obligations under this AGREEMENT in any material
respect and (ii) such failure continues for a period of thirty (30) days after
receipt by the other party of notice thereof from the party

                                       38

<PAGE>

specifying such failure. In the event of a non-monetary breach, if the breach is
not reasonably capable of being cured within the thirty (30) day period, and the
breaching party is making a good faith effort to cure the breach, the notifying
party may not terminate this AGREEMENT pursuant to this Section without a
further sixty (60) days elapsing from the original notice of breach without the
breach having been cured.

     14.3 TERMINATION FOR BANKRUPTCY. Because each party acknowledges that the
services to be rendered by the other are special i.e. personal in nature
inasmuch as the respective capabilities of the parties hereto are uniquely
valuable and that the determination to enter into this AGREEMENT was based upon
the unique ability of the other party to fulfill its respective obligations
hereunder, a party shall have the right to immediately terminate this AGREEMENT,
if (i) the other party shall make an assignment of substantially all of its
assets for the benefit of creditors, file a petition in bankruptcy, petition or
apply to any tribunal for the appointment of a custodian, receiver or any
trustee for such party or substantially all of such party's assets, or shall
commence any proceeding under any bankruptcy, reorganization in bankruptcy or
the equivalent, dissolution or liquidation law or statute of any jurisdiction
(provided that no entity succeeds to the business of such party following such
dissolution or liquidation) whether now or hereafter in effect; or (ii) there
shall have been filed any such petition or application against the other party,
or any such proceeding shall have been commenced against the other party, in
which an order for relief is entered or which remains undismissed for a period

failure to act shall indicate the other party's consent to, approval of or
acquiescence in, any such petition, application or proceeding or order for

suffer any such custodianship, receivership or trusteeship to continue
undischarged for a period of ninety (90) days or more or (iv) the other party is
insolvent.

SECTION 15. RIGHTS AND DUTIES UPON TERMINATION

     15.1 PAYMENT. Upon termination or expiration of this AGREEMENT other than

sums which might then be due hereunder.

                                       39

<PAGE>

     15.2 SALE OF REMAINING INVENTORY. Upon termination or expiration of this
AGREEMENT, DISTRIBUTOR shall notify BTI of the amount of PRODUCT DISTRIBUTOR and
its AFFILIATES and its and their SUBDISTRIBUTORS then have on hand. DISTRIBUTOR
and its SUBDISTRIBUTORS shall be permitted to sell that amount of PRODUCT for a
period of ninety (90) days following such termination.

          (a) Any inventory of DISPOSABLE PRODUCTS remaining after such 90 day
     period shall either be returned to BTI for repurchase (less BTI's standard
     restocking fee) if the PRODUCT has a remaining shelf life as specified in
     section 4.8 or be destroyed.

          (b) If any EQUIPMENT purchased by DISTRIBUTOR has been loaned to an
     END USER at no charge and this AGREEMENT merely expires or is terminated
     through no fault of DISTRIBUTOR, BTI will reimburse DISTRIBUTOR in the
     amount of DISTRIBUTOR's net book value (assuming a three year straight line
     depreciation) for any such EQUIPMENT which is in good and marketable
     condition, paying such net book value in equal installments within the
     first fifteen (15) days of the QUARTER during the remaining portion of the
     three year useful life. If this AGREEMENT is terminated for DISTRIBUTOR's
     uncured default, BTI shall have the right but not the duty to make such
     reimbursement. Upon tender of the final payment for such EQUIPMENT,
     DISTRIBUTOR will transfer title to such EQUIPMENT to BTI.

          (c) If any EQUIPMENT purchased by DISTRIBUTOR has been sold to an END
     USER subject to financing, either on a "cost-per-treatment" basis or other
     financing arrangement, and this AGREEMENT merely expires or is terminated
     through no fault of DISTRIBUTOR, BTI will reimburse DISTRIBUTOR in the
     amount of DISTRIBUTOR's net book value (assuming a three year straight line
     depreciation) for any such EQUIPMENT which is in good and marketable
     condition, paying such net book value in equal installments within the
     first fifteen (15) days of the QUARTER during the remaining portion of the
     three year useful life. If this AGREEMENT is terminated for DISTRIBUTOR's
     uncured default, BTI shall have the right but not the duty to make such
     reimbursement. Upon BTI's agreeing to make such reimbursement and tendering
     the first

                                       40

<PAGE>

     payment for such EQUIPMENT, DISTRIBUTOR will assign to BTI all
     DISTRIBUTOR's rights to receive payment from the END USER for such
     EQUIPMENT.

     15.3 SURVIVAL. Upon expiration or termination of this AGREEMENT, all rights
and obligations of the parties under this AGREEMENT shall terminate except those
described in Sections 2.1(b), 4.6, 5.3, 8.3, 5.4, 10.2, 12.4, 15.1, 15.2, 15.3,
15.5,17.3 and Sections 11, and 16. Any monies owing to the parties (whether as
credits or offsets against future payments) shall be reconciled and paid within
sixty (60) days of expiration or termination.

     It is understood that termination or expiration of this AGREEMENT shall not
relieve a party from any liability which, at the time of such termination or
expiration, has already accrued to the other party or which is attributable to a
period prior to such termination. Termination or expiration of the AGREEMENT in
accordance with the provisions hereof shall not limit remedies which may be
otherwise available in law or equity with respect to a breach hereof that
occurred prior to such termination except to the extent expressly stated herein.

     15.4 WAIVER OF BREACH. The failure of either party at any time or times to
require performance of any provision hereof shall in no manner affect its rights
at a later time to enforce the same. No waiver by either party of any condition
or term in any one or more instances shall be construed as a further or
continuing waiver of such condition or term or of another condition or term.

     15.5 TERMINATION OF PRODUCT SALES. Upon termination of this AGREEMENT,
subject to Section 15.2, DISTRIBUTOR agrees not to market or sell PRODUCT in the
TERRITORY after termination of this AGREEMENT, or in such country(ies) in which
DISTRIBUTOR'S rights have been terminated, as the case may be.

SECTION 16. ARBITRATION

     In the event of any dispute, claim or controversy (a "Claim") arising out
of or relating to this Agreement or the purchase of Products hereunder, the
parties agree to submit the Claim to the JCs for their members to make a good
faith attempt to negotiate an amicable resolution to any and all

                                       41

<PAGE>

such Claims. If any Claim is not resolved by the JCs within thirty (30) days
after delivery of written notice thereof from one party to the other party, the
Claim shall be referred to the OVERSIGHT COMMITTEE in accordance with Section
3.1(d) of this AGREEMENT. If the OVERSIGHT COMMITTEE is unable resolve the Claim
within thirty (30) days after the JC refers the matter, the resolution will be
determined through binding arbitration in accordance with the Commercial Rules
of Arbitration of the American Arbitration Association. The site of the
arbitration shall be Chicago, Illinois or such other neutral location as the
OVERSIGHT COMMITTEE may select.

     The arbitration panel shall be comprised of three (3) arbitrators. The
parties will seek arbitrators who are experienced in the area of sales and
marketing of products similar to PRODUCTS, but such arbitrators need not be
lawyers or judges. Each party shall be entitled to appoint one arbitrator. The
parties shall appoint their respective arbitrators within thirty (30) days after
submission for arbitration. If either party shall fail to make timely
appointment of its arbitrator, the arbitration shall be heard and decided by the
sole arbitrator duly appointed by the other party. Where both parties have
timely appointed their respective arbitrators, the two arbitrators so appointed
shall agree on the appointment of the third arbitrator from the list of
arbitrators maintained by the American Arbitration Association. If the parties'
appointed arbitrators shall fail to agree on the identity of the third
arbitrator within thirty (30) days from the date both parties' arbitrators have
been appointed, then such arbitrator shall be appointed by the appropriate
administrative body of the American Arbitration Association.

     Within ten (10) days of appointment of the full arbitration panel, the
parties shall exchange their final proposed positions with respect to the
matters to be arbitrated, which shall approximate as closely as possible the
closest positions of the parties previously taken in the negotiations. Within
thirty (30) days of appointment of the arbitration Panel, each party shall
submit to the arbitrators a copy of the proposed position which it previously
delivered to the other party, together with a brief or other written memorandum
supporting the merits of its proposed position. The parties may include with
such memorandum whatever documentary evidence they deem appropriate to support
their position, provided that all pages of the memorandum and attachments will
not exceed one hundred pages. The arbitration panel shall promptly convene a
hearing, at which time each party shall have four (4) hours to argue in support
of its proposed position. The

                                       42

<PAGE>

parties may present witnesses in support of their arguments so long as such
testimony does not exceed the four hour limit.

     In making their selection, the arbitrators shall consider the terms and
conditions of this AGREEMENT, the relative merits of the proposed position and
the written and oral arguments of the parties. In the event the arbitrators seek
the guidance of the law of any jurisdiction, the law of the Commonwealth of
Massachusetts shall govern.

     The arbitrators shall make their decision known to the parties as quickly
as possible by delivering written notice of their decision to both parties. Such
written notice need not justify their decision. The parties will execute any and
all papers necessary to obligate the parties to the position selected by the
arbitration panel within five (5) days of receipt of notice of such selection.
The decision of the arbitrators shall be final and binding on the parties, and
specific performance may be ordered by any court of competent jurisdiction.

     The parties will bear their own costs in preparing for the arbitration. The
costs of the arbitrators will be equally divided between the parties. If a party
is required to initiate proceedings to enforce the decision of the arbitrators,
the prevailing party shall be entitled to recover its costs and attorneys' fees
associated with such action.

SECTION 17. GENERAL PROVISIONS

     17.1 AFFILIATES AND SUBDISTRIBUTORS. DISTRIBUTOR may perform its
obligations and exercise its rights under this AGREEMENT personally or through

AFFILIATES to commit any act (including any act of omission) which DISTRIBUTOR
is prohibited hereunder from committing directly. Subject to Section 2.4,

excused from such performance to the extent of such prevention, restriction,
interference or delay, provided that the affected party shall use its reasonable
efforts to avoid or remove such causes of non-performance and shall continue

adversely affected by such holding may terminate this AGREEMENT by sixty (60)
days' prior notice to the other party.

     17.5 ENTIRE AGREEMENT. This AGREEMENT, entered into as of the date written
above, constitutes the entire agreement between the parties relating to the
subject matter hereof and supersedes all previous writings and understandings
with respect thereto. No terms or provisions of this AGREEMENT shall be varied
