                  AGREEMENT AND PLAN OF MERGER, dated as of October 16, 2006
(this "Agreement"), among LEVEL 3 COMMUNICATIONS, INC., a Delaware corporation
("Parent"), LEVEL 3 SERVICES, LLC, a Delaware limited liability company and a
direct wholly owned Subsidiary of Parent ("Merger Sub"), LEVEL 3 COLORADO, INC.,
a Delaware corporation and a direct wholly owned Subsidiary of Parent ("Sister
Subsidiary"), and BROADWING CORPORATION, a Delaware corporation (the "Company").


                              W I T N E S S E T H:
                               - - - - - - - - - -

                  WHEREAS, the respective Boards of Directors of Parent and the
Company and the Board of Managers of Merger Sub have each approved and declared
advisable the merger of the Company with and into Merger Sub (the "Merger"),
upon the terms and subject to the conditions set forth in this Agreement,
pursuant to which each outstanding share of common stock, par value $0.01 per
share, of the Company ("Company Common Stock") issued and outstanding
immediately prior to the Effective Time, other than Dissenting Shares, will be
converted into the right to receive a combination of cash and shares of common
stock, par value $0.01 per share, of Parent ("Parent Common Stock");

                  WHEREAS, as a condition to Parent entering into this Agreement
and incurring the obligations set forth herein, concurrently with the execution
and delivery of this Agreement, Parent is entering into a Voting Agreement with
certain affiliated stockholders of the Company (the "Voting Agreement") pursuant
to which, among other things, each of those stockholders has agreed, subject to
the terms thereof, to vote all shares of Company Common Stock owned by such
stockholder in accordance with the terms of the Voting Agreement;

                  WHEREAS, Parent, Merger Sub and the Company desire to make
certain representations, warranties, covenants and agreements in connection with
the transactions contemplated hereby and also to prescribe various conditions to
the transactions contemplated hereby; and

                  WHEREAS, for federal income tax purposes, Parent, Merger Sub
and the Company intend that the merger shall qualify as a reorganization within
the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended
(the "Code"), and the regulations promulgated thereunder ("Treasury
Regulations"), and, by approving resolutions authorizing this Agreement, to
adopt this Agreement as a plan of reorganization within the meaning of Section
368(a) of the Code and the Treasury Regulations.

                  NOW, THEREFORE, in consideration of the foregoing and the
respective representations, warranties, covenants and agreements set forth
herein, and intending to be legally bound hereby, the parties hereto agree as
follows:


                                   ARTICLE I.

                                   THE MERGER

     Section 1.1.  The Merger. Upon the terms and subject to the conditions
hereof, at the Effective Time, the Company shall be merged with and into Merger
Sub and the separate existence of the Company shall thereupon cease, and Merger
Sub, as the surviving entity in the Merger (the "Surviving Company"), shall by
virtue of the Merger continue its existence under the laws of the State of
Delaware. If the Requisite Consent has not been obtained on or prior to the
Conversion Date, the "Merger" shall instead be a merger (upon the terms and
subject to the conditions set forth in this Agreement) of Merger Sub with and
into the Company at the Effective Time, in which case, the separate existence of
Merger Sub shall cease upon the Merger and the Company, as the surviving entity
in the Merger, shall continue as the Surviving Company. Such change to the terms
of the Merger on the Conversion Date in accordance with the prior sentence shall
be referred to as a "Conversion Event." If there is a Conversion Event, Parent
shall cause Merger Sub, prior to the Effective Time, to be converted into a
corporation pursuant to Section 265 of the DGCL.

     Section 1.2.  Subsequent Merger.

     (a) If there is a Conversion Event, (i) Parent, Merger Sub, Sister
Subsidiary and the Company shall, promptly after the Conversion Date, amend this
Agreement to include representations, warranties and covenants of Sister
Subsidiary which are substantially equivalent to the representations, warranties
and covenants of Merger Sub and such other changes to this Agreement as may be
reasonably necessary to effect the Merger following the Conversion Event and the
Subsequent Merger discussed below and (ii) immediately following the Effective
Time and in accordance with the DGCL, Parent shall cause the Surviving Company
to merge with and into Sister Subsidiary and the separate corporate existence of
the Surviving Company shall thereupon cease (the "Subsequent Merger") and Sister
Subsidiary, as the surviving corporation in the Subsequent Merger, shall by
virtue of the Subsequent Merger continue its existence under the laws of the
State of Delaware. At the effective time of the Subsequent Merger and without
any further action on the part of the Surviving Company, Parent, Sister
Subsidiary or any holder of any capital stock of the Surviving Company, Parent
or Sister Subsidiary, each share of common stock, par value $0.0001 per share,
of the Surviving Company issued and outstanding immediately prior to the
effective time of the Subsequent Merger shall be converted into one share of
common stock, par value $0.0001 per share, of Sister Subsidiary.

     (b) In the event of the Subsequent Merger, references herein to the
"Surviving Company" shall refer after the effective time of the Subsequent
Merger, to Sister Subsidiary.

     (c) If there is a Conversion Event, this Agreement is intended to
constitute a "plan of reorganization" with respect to the Merger and Subsequent
Merger, taken together, for United States federal income tax purposes pursuant
to which, for such purposes, the Merger and the Subsequent Merger, taken
together, are to be treated as a "reorganization" under Section 368(a) of the
Code (to which each of Parent, Sister Subsidiary and the Company are to be
parties under Section 368(b) of the Code) in which the Company is to be treated
as merging directly

                                       2


with and into Sister Subsidiary with the Company Common Stock converted in such
merger into the right to receive the consideration provided for hereunder.

     Section 1.3.  Closing. Unless this Agreement shall have been terminated
pursuant to the provisions of Section 9.1, the closing of the Merger (the
"Closing") will take place on the third Business Day after the satisfaction or
waiver (subject to applicable law) of the conditions (excluding conditions that,
by their terms, cannot be satisfied until the Closing Date, but subject to the
satisfaction or, where permitted, waiver of those conditions as of the Closing)
set forth in Article VIII, unless another time or date is agreed to in writing
by the parties hereto (the date of the Closing, the "Closing Date"). The Closing
shall be held at the offices of Willkie Farr & Gallagher LLP, 787 Seventh
Avenue, New York, New York 10019, unless another place is agreed to in writing
by the parties hereto.

     Section 1.4.  Effective Time. Upon the Closing, the parties shall file
with the Secretary of State of the State of Delaware a certificate of merger
(the "Certificate of Merger"). The Merger shall become effective at such time as
the Certificate of Merger is duly filed with the Secretary of State of the State
of Delaware or at such subsequent time as Parent and the Company shall agree and
as shall be specified in the Certificate of Merger (the date and time the Merger
becomes effective being the "Effective Time").

     Section 1.5.  Effects of the Merger. The Merger shall have the effects
set forth in the LLCA or, if there is a Conversion Event, the DGCL. Without
limiting the generality of the foregoing, and subject thereto, at the Effective
Time, all the property, rights, privileges, powers, and franchises of the
Company and Merger Sub shall vest in the Surviving Company, and all debts,
liabilities and duties of the Company and Merger Sub shall become the debts,
liabilities and duties of the Surviving Company.

     Section 1.6.  Certificate of Formation. Unless there is a Conversion
Event, the certificate of formation of Merger Sub shall be the certificate of
formation of the Surviving Company after the Effective Time, and thereafter may
be amended as provided therein or by law, except that the certificate of
formation of the Surviving Company shall be amended to provide that the name of
the Surviving Company is "Broadwing LLC." If there is a Conversion Event, the
certificate of incorporation of Merger Sub shall be the certificate of
incorporation of the Surviving Company after the Effective Time, and thereafter
may be amended as provided therein or by law, except that the certificate of
incorporation of the Surviving Company shall be amended to provide that the name
of the Surviving Company is "Broadwing Corporation."

     Section 1.7.  Operating Agreement. Unless there is a Conversion Event,
the operating agreement of Merger Sub as in effect at the Effective Time shall
be the operating agreement of the Surviving Company, and thereafter may be
amended as provided therein or by law. If there is a Conversion Event, the
bylaws of Merger Sub as in effect at the Effective Time shall be the bylaws of
the Surviving Company, and thereafter may be amended as provided therein or by
law.

     Section 1.8.  Managers; Officers. Unless there is a Conversion Event,
the managers and officers of Merger Sub immediately prior to the Effective Time
shall be the managers and officers of the Surviving Company until their
respective successors are duly

                                       3


elected and qualified or until their death, resignation or removal in accordance
with the LLCA and the certificate of formation and operating agreement of the
Surviving Company. If there is a Conversion Event, the directors and officers of
Merger Sub immediately prior to the Effective Time shall be the directors and
officers of the Surviving Company until their respective successors are duly
elected and qualified or until their death, resignation or removal in accordance
with the DGCL and the certificate of incorporation and bylaws of the Surviving
Company.

     Section 1.9.  Effect on Capital Stock. At the Effective Time by virtue
of the Merger and without any action on the part of the holder thereof:

     (a) Each share of Company Common Stock issued and outstanding immediately
prior to the Effective Time (other than any Dissenting Shares), shall be
converted into the right to receive (i) 1.3411 (the "Exchange Ratio") fully paid
and nonassessable shares of Parent Common Stock, subject to Section 2.5 with
respect to fractional shares (the "Stock Consideration"), and (ii) $8.18 in cash
(the "Cash Consideration" and, together with the Stock Consideration, the
"Merger Consideration").

     (b) All shares of Company Common Stock (other than shares referred to in
Section 1.9(d)) shall cease to be outstanding and shall be canceled and retired
and shall cease to exist, and each holder of a certificate which immediately
prior to the Effective Time represented any such shares of Company Common Stock
(a "Certificate") shall thereafter cease to have any rights with respect to such
shares of Company Common Stock, except the right to receive the applicable
Merger Consideration and any dividends or other distributions to which holders
become entitled all in accordance with Article II upon the surrender of such
Certificate.

     (c) Unless there is a Conversion Event, each membership interest of Merger
Sub issued and outstanding immediately prior to the Effective Time shall remain
issued, outstanding and unchanged as a membership interest of the Surviving
Company. If there is a Conversion Event, each share of common stock, par value
$0.0001 per share, of Merger Sub issued and outstanding immediately prior to the
Effective Time shall be converted into one share of common stock, par value
$0.0001 per share, of the Surviving Company.

     (d) Notwithstanding anything in this Agreement to the contrary, shares of
Company Common Stock that are issued and outstanding immediately prior to the
Effective Time and that are owned by stockholders that have properly perfected
their rights of appraisal within the meaning of Section 262 of the DGCL (the
"Dissenting Shares") shall not be converted into the right to receive the Merger
Consideration, unless and until such stockholders shall have failed to perfect
any available right of appraisal under applicable law, but, instead, the holders
thereof shall be entitled to payment of the appraised value of such Dissenting
Shares in accordance with Section 262 of the DGCL. If any such holder shall have
failed to perfect or shall have effectively withdrawn or lost such right of
appraisal, the shares of Company Common Stock held by such stockholder shall not
be deemed Dissenting Shares for purposes of this Agreement and shall thereupon
be deemed to have been converted into the Merger Consideration at the Effective
Time in accordance with Section 1.9(a). The Company shall give Parent (A) prompt
notice of any demands for appraisal filed pursuant to Section 262 of the DGCL
received by the Company, withdrawals of such demands and any other instruments
served or delivered in

                                       4


connection with such demands pursuant to the DGCL and received by the Company
and (B) the opportunity to participate in all negotiations and proceedings with
respect to demands made pursuant to Section 262 of the DGCL. The Company shall
not, except with the prior written consent of Parent, (x) make any payment with
respect to any such demand, (y) offer to settle or settle any such demand or (z)
waive any failure to timely deliver a written demand for appraisal or timely
take any other action to perfect appraisal rights in accordance with the DGCL.

     (e) If prior to the Effective Time, Parent or the Company, as the case may
be, should split, combine or otherwise reclassify the Parent Common Stock or the
Company Common Stock, or pay a stock dividend or other stock distribution in
Parent Common Stock or Company Common Stock, as applicable, or otherwise change
the Parent Common Stock or Company Common Stock into any other securities, or
make any other such stock dividend or distribution in capital stock of Parent or
the Company in respect of the Parent Common Stock or the Company Common Stock,
respectively, then any number or amount contained herein which is based upon the
price of the Parent Common Stock or the number of shares of Company Common Stock
or Parent Common Stock, as the case may be, will be appropriately adjusted to
reflect such split, combination, dividend or other distribution or change.

     Section 1.10.  Treatment of Options, Warrants and Other Stock Awards.

     (a) The Company shall take all actions necessary and appropriate to provide
that upon the Effective Time, each outstanding employee, director or consultant
stock option to purchase Company Common Stock (collectively, "Company Options")
granted under any Company Stock Plan whether or not then exercisable or vested,
shall be cancelled and, in exchange therefor, each holder of such Company Option
shall receive: (i) an amount in cash in respect thereof, if any, equal to the
product of (x) the Cash Percentage, (y) the excess, if any, of the Deemed Value
of Merger Consideration over the per share exercise price thereof and (z) the
number of shares of Company Common Stock subject to such Company Option (such
cash payment to be net of applicable withholding taxes); and (ii) a number of
shares of Parent Common Stock in respect thereof, if any, equal to the quotient
of (A) the product of (x) the Stock Percentage, (y) the excess, if any, of the
Deemed Value of Merger Consideration over the per share exercise price thereof
and (z) the number of shares of Company Common Stock subject to such Company
Option divided by (B) the Parent Common Stock Price, provided, that any
fractional shares that would otherwise be issuable pursuant to this Section
1.10(a) shall be rounded up to the nearest whole number.

     (b) All shares of restricted Company Common Stock granted under the Company
Stock Plans (and any other shares of Company Common Stock subject to vesting or
future issuance under the Company Stock Plans) (collectively, "Other Stock
Awards") outstanding immediately prior to the Effective Time, whether or not
then vested, shall be treated in the same manner as all other shares of Company
Common Stock outstanding immediately prior to the Effective Time pursuant to
Section 1.9 of this Agreement and all such Other Stock Awards shall be fully
vested as of the Effective Time.

     (c) At the Effective Time, each unexercised warrant to purchase shares of
Company Common Stock (the "Company Warrants") then outstanding will be assumed
by Parent, in accordance with the terms of such Company Warrants. Each such
outstanding

                                       5


Company Warrant so assumed by Parent under this Agreement will continue to have,
and be subject to, the same terms and conditions set forth in such Company
Warrants immediately prior to the Effective Time, except as modified as a result
of the Merger pursuant to the terms of such Company Warrants.

     (d) With respect to the Company's Employee Stock Purchase Plan (the
"ESPP"), the Company shall take all actions necessary to (i) cause the current
Offering Period (within the meaning of the ESPP) to terminate at the Effective
Time (if the Effective Time is earlier than the date the current Offering Period
would otherwise terminate); (ii) prevent any further contributions to the
current Offering Period after the date hereof, and (iii) refrain from commencing
any new Offering Periods under the ESPP thereafter.

     (e) Unless there is a Conversion Event, the Surviving Company shall, upon
the Effective Time, succeed to and be substituted for the Company under the
Indenture. Following the Effective Time, the Convertible Debentures will
thereafter be convertible upon the terms and subject to the conditions set forth
in the Indenture after giving effect to the Merger and any notice delivered by
the Company pursuant to Section 5.4 of this Agreement.

     (f) The Company and Parent shall take all such steps as may be required to
cause the transactions contemplated by this Section 1.10 and any other
dispositions of Company equity securities (including derivative securities) or
acquisitions of Parent equity securities (including derivative securities) in
connection with this Agreement by each individual who (i) is a director or
officer of the Company or (ii) at the Effective Time will become a director or

Exchange Act.

                               ARTICLE II.

                            EXCHANGE OF CERTIFICATES

     Section 2.1.  Exchange Fund. At or prior to the Effective Time, Parent
shall deposit with Wells Fargo Bank, N.A. or such other bank or trust company as
Parent shall determine and who shall be reasonably satisfactory to the Company
(the "Exchange Agent"), in trust for the benefit of holders of shares of Company
Common Stock, for exchange in accordance with Section 1.9, (i) certificates
representing the number of shares of Parent Common Stock sufficient to deliver,
and Parent shall instruct the Exchange Agent to timely deliver, in accordance
with the terms of Section 2.2 of this Agreement, the aggregate Stock
Consideration, and (ii) immediately available funds equal to the aggregate Cash
Consideration and Parent shall instruct the Exchange Agent to timely pay the
Cash Consideration subject to and in accordance with the terms of Section 2.2 of
this Agreement. Parent agrees to make available to the Exchange Agent from time
to time as needed, cash sufficient to pay any dividends and other distributions
pursuant to Section 2.3. Any cash and certificates of Parent Common Stock
deposited with the Exchange Agent shall hereinafter be referred to as the
"Exchange Fund."

     Section 2.2.  Exchange Procedures. As promptly as practicable after the
Effective Time, the Exchange Agent will send to each record holder of a
Certificate other than Certificates in respect of Dissenting Shares, (i) a
letter of transmittal (which shall specify that delivery shall be effected, and
risk of loss and title to the Certificates shall pass, only upon

                                       6


delivery of the Certificates to the Exchange Agent and shall be in a form and
have such other provisions as Parent may reasonably specify) and (ii)
instructions for use in effecting the surrender of the Certificates in exchange
for the Merger Consideration. As soon as reasonably practicable after the
Effective Time, each holder of a Certificate, upon surrender of a Certificate to
the Exchange Agent together with such letter of transmittal, duly executed, and
such other documents as may reasonably be required by the Exchange Agent, shall
be entitled to receive in exchange therefor a certificate or certificates
representing the number of full shares of Parent Common Stock and the amount of
cash (including amounts to be paid pursuant to Section 1.9(a) and in respect of
any dividends or other distributions to which holders are entitled pursuant to
Section 2.3, if any), into which the aggregate number of shares of Company
Common Stock previously represented by such Certificate shall have been
converted pursuant to this Agreement. The Exchange Agent shall accept such
Certificates upon compliance with such reasonable terms and conditions as the
Exchange Agent may impose to effect an orderly exchange thereof in accordance
with normal exchange practices. No interest will be paid or will accrue on any
cash payable pursuant to Section 1.9(a) or 2.3. In the event of a transfer of
ownership of Company Common Stock which is not registered in the transfer
records of the Company, one or more shares of Parent Common Stock evidencing, in
the aggregate, the proper number of shares of Parent Common Stock, a check in
the proper amount of cash pursuant to Section 1.9(a) and any dividends or other
distributions to which such holder is entitled pursuant to Section 2.3, may be
issued with respect to such Company Common Stock to such a transferee only if
the Certificate representing such shares of Company Common Stock is presented to
the Exchange Agent, accompanied by all documents required to evidence and effect
such transfer and to evidence that any applicable stock transfer taxes have been
paid.

     Section 2.3.  Distributions with Respect to Unexchanged Shares. No
dividends or other distributions declared or made with respect to shares of
Parent Common Stock with a record date after the Effective Time shall be paid to
the holder of any unsurrendered Certificate with respect to the shares of Parent
Common Stock that such holder would be entitled to receive upon surrender of
such Certificate. Subject to the effect of applicable laws, following surrender
of any such Certificate, there shall be paid to such holder of shares of Parent
Common Stock issuable in exchange therefor, without interest, (a) promptly after
the time of such surrender, the amount of dividends or other distributions with
a record date after the Effective Time theretofore paid with respect to such
whole shares of Parent Common Stock, and (b) at the appropriate payment date,
the amount of dividends or other distributions with a record date after the
Effective Time but prior to such surrender and a payment date subsequent to such
surrender payable with respect to such shares of Parent Common Stock.

     Section 2.4.  No Further Ownership Rights in Company Common Stock. All
shares of Parent Common Stock issued and cash paid upon conversion of shares of
Company Common Stock in accordance with the terms of Article I and this Article
II (including any cash paid pursuant to Section 2.3) shall be deemed to have
been issued or paid in full satisfaction of all rights pertaining to the shares
of Company Common Stock.

     Section 2.5.  No Fractional Shares of Parent Common Stock. No
certificates or scrip representing less than one share of Parent Common Stock
shall be issued upon the surrender for exchange of Certificates representing
Company Common Stock pursuant to Section

                                       7


1.9 hereof. Any fractional shares that would otherwise be issuable pursuant to
Section 1.9 hereof shall be rounded up to the nearest whole number.

     Section 2.6.  Termination of Exchange Fund. Any portion of the Exchange
Fund which remains undistributed to the holders of Certificates for six months
after the Effective Time shall be delivered to the Surviving Company or
otherwise on the instruction of the Surviving Company, and any holders of
Certificates who have not theretofore complied with this Article II shall
thereafter look only to the Surviving Company and Parent (subject to abandoned
property, escheat or other similar laws) for the Merger Consideration with
respect to the shares of Company Common Stock formerly represented thereby to
which such holders are entitled pursuant to Section 1.9 and any dividends or
distributions with respect to shares of Parent Common Stock to which such
holders are entitled pursuant to Section 2.3.

     Section 2.7.  No Liability. None of Parent, Merger Sub, the Company,
the Surviving Company or the Exchange Agent shall be liable to any Person in
respect of any Merger Consideration from the Exchange Fund delivered to a public
official pursuant to any applicable abandoned property, escheat or similar law.

     Section 2.8.  Investment of the Exchange Fund. Any funds included in
the Exchange Fund may be invested by the Exchange Agent, as directed by Parent;
provided that such investments shall be in obligations of or guaranteed by the
United States of America and backed by the full faith and credit of the United
States of America or in commercial paper obligations rated A-1 or P-1 or better
by Moody's Investors Services, Inc. or Standard & Poor's Corporation,
respectively. Any interest and other income resulting from such investments
shall promptly be paid to Parent.

     Section 2.9.  Lost Certificates. If any Certificate shall have been
lost, stolen or destroyed, upon the making of an affidavit of that fact by the
Person claiming such Certificate to be lost, stolen or destroyed and, if
required by the Surviving Company, the posting by such Person of a bond in such
reasonable amount as the Surviving Company may direct as indemnity against any
claim that may be made against it with respect to such Certificate, the Exchange
Agent will deliver in exchange for such lost, stolen or destroyed Certificate
the applicable Merger Consideration with respect to the shares of Company Common
Stock formerly represented thereby, and any unpaid dividends and distributions
on shares of Parent Common Stock deliverable in respect thereof, pursuant to
this Agreement.

     Section 2.10.  Withholding Rights. Each of the Surviving Company and
Parent shall be entitled to deduct and withhold from the consideration otherwise
payable pursuant to this Agreement to any holder of shares of Company Common
Stock and any holder of Company Options such amounts as it is required to deduct
and withhold with respect to the making of such payment under the Code and the
rules and regulations promulgated thereunder, or any provision of state, local
or foreign tax law. To the extent that amounts are so withheld by the Surviving
Company or Parent, as the case may be, such withheld amounts shall be treated
for all purposes of this Agreement as having been paid to the holder of the
shares of Company Common Stock in respect of which such deduction and
withholding was made by the Surviving Company or Parent, as the case may be.

                                       8


     Section 2.11.  Further Assurances. At and after the Effective Time, the
officers and directors of the Surviving Company will be authorized to execute
and deliver, in the name and on behalf of the Company or Merger Sub, any deeds,
bills of sale, assignments or assurances and to take and do, in the name and on
behalf of the Company or Merger Sub, any other actions and things to vest,
perfect or confirm of record or otherwise in the Surviving Company any and all
right, title and interest in, to and under any of the rights, properties or
assets acquired or to be acquired by the Surviving Company as a result of, or in
connection with, the Merger.

     Section 2.12.  Stock Transfer Books. At the close of business, New York
time, on the day the Effective Time occurs, the stock transfer books of the
Company shall be closed and there shall be no further registration of transfers
of shares of Company Common Stock thereafter on the records of the Company. From
and after the Effective Time, the holders of Certificates shall cease to have
any rights with respect to such shares of Company Common Stock formerly
represented thereby, except as otherwise provided herein or by law. On or after
the Effective Time, any Certificates presented to the Exchange Agent or Parent
for any reason shall be converted into the Merger Consideration with respect to
the shares of Company Common Stock formerly represented thereby, and any
dividends or other distributions to which the holders thereof are entitled
pursuant to Section 2.3.

                                  ARTICLE III.

                  REPRESENTATIONS AND WARRANTIES OF THE COMPANY

     Except as disclosed in the Company SEC Reports filed since January 1, 2006
and prior to the date hereof (but excluding matters disclosed in the sections of

defaults that would not, individually or in the aggregate, have a Company
Material Adverse Effect.

or approval of any Governmental Entity, and no declaration or notice to or
filing or registration with any Governmental Entity, is required in connection
with the execution and delivery of this Agreement by the Company or the
performance by the Company or its Subsidiaries of their obligations hereunder or

obligations hereunder and the consummation of the transactions contemplated
hereby have been duly authorized by the Board of Directors of the Company and
all other necessary corporate action on the part of the Company, other than the
adoption of this Agreement by the stockholders of the Company, and no other
corporate proceedings on the part of the Company are necessary to authorize this
Agreement and the transactions contemplated hereby. This Agreement has been duly

                       COVENANTS OF PARENT AND MERGER SUB.

     Section 6.1.  Employee Benefits.

     (a) For a period of one year following the Effective Time, Parent shall, or
shall cause the Surviving Company to maintain, without interruption, employee
benefit plans, programs and policies and fringe benefits (other than severance
or similar benefits, which shall be provided in accordance with subsection (c)
below) that will provide benefits to the employees of the Company and its
Subsidiaries who continue their employment with the Surviving Company or who
become employees of Parent or any Subsidiary of Parent ("Continuing Employees")
that are, in the aggregate, not less favorable than those currently provided to
such employees by the Company and its Subsidiaries. Continuing Employees shall
be given credit for all service with the Company and its Subsidiaries (and their
respective predecessors) (or service credited by the Company and its
Subsidiaries for similar plans, programs or policies) under all employee benefit
and fringe benefit plans, programs and policies of the Parent or its affiliates
in which they become participants for purposes of eligibility, vesting and level
of benefits (except to the extent such service credit will result in benefit
accrual under any defined benefit pension plans or otherwise result in a
duplication of benefits).

     (b) If a Continuing Employee becomes eligible to participate in any
medical, dental or health plan of the Parent or any of its affiliates, Parent
shall cause such plan to (A) waive any preexisting condition limitations for
conditions covered under the applicable medical, health or dental plans of the
Company (the "Company Welfare Plans") and (B) honor any deductible and
out-of-pocket expenses incurred by such employee and his or her beneficiaries
under the Company Welfare Plans during the portion of the applicable plan year
preceding the Closing. If such Continuing Employee becomes eligible to
participate in a group term life insurance plan maintained by Parent or any of
its affiliates, Parent shall cause such plan to waive any medical certification
for such employee in order to provide benefits that do not exceed the benefits
under Parent's group term life insurance plan.

     (c) For a period of one year following the Effective Time, Parent shall, or
shall cause the Surviving Company, to provide severance and COBRA benefits to
the Continuing Employees, other than those Continuing Employees who are subject
to the agreements set forth on Schedule 3.9(b)(viii), as set forth on Schedule
6.1(c).

     (d) Following the date of this Agreement and until the Effective Time, the
Company shall operate the Company's 2006 Bonus Plan (the "2006 Bonus Plan") in
accordance with the terms and conditions of the 2006 Bonus Plan. If the bonuses
under the 2006 Bonus Plan are not paid by the Company prior to Effective Time,
following the Effective Time and on or prior to February 28, 2007 (or if the
Closing has not occurred on or prior to February 28, 2007, within ten Business
Days of Closing), Parent shall cause the Surviving Company to pay (i) to the
participants in the 2006 Bonus Plan in accordance with the terms of such plan as
set forth on

                                       37


Schedule 6.1(d), (ii) in an aggregate amount determined in accordance with the
2006 Bonus Plan as set forth on Schedule 6.1(d) and (iii) to each participant in
such specific amount as communicated in writing by management of the Company
prior to the Effective Time; provided, however, that notwithstanding the terms
of the 2006 Bonus Plan, all participants otherwise entitled to receive a bonus
in the 2006 Bonus Plan who are employed on the earlier of December 31, 2006 and
the Closing shall be paid their bonuses under the 2006 Bonus Plan, unless the
participant's employment with the Company or its Subsidiaries (or, if
applicable, the Surviving Company or its Subsidiaries) has terminated prior to
the payment date either (i) for "cause" (as defined in such participant's
employment agreement, severance agreement or offer letter or if the participant
does not have an employment agreement, severance agreement or offer letter that
defines "cause", the Company's 2000 Long Term Incentive Plan as of the date of
this Agreement) or (ii) the participant voluntarily terminates such
participant's employment, except where the participant terminated his or her
employment for "Good Reason" or as a result of a "Constructive Termination" (as
defined in such participant's employment agreement, severance agreement or offer
letter or if the participant does not have an employment agreement, severance
agreement or offer letter that defines "Good Reason" or "Constructive
Termination," the Company's 2000 Long Term Incentive Plan as of the date of this
Agreement). Notwithstanding anything to the contrary in the foregoing, Parent
shall not be required to cause the Surviving Company to pay any amounts under
the 2006 Bonus Plan unless, as of September 30, 2006, the Company had accrued an
aggregate liability with respect to its obligations under the 2006 Bonus Plan as
set forth on Schedule 3.20(l).

     (e) After the date hereof, the Company shall adopt a special bonus plan
(the "Special Bonus Plan") under which management of the Company, in its sole
discretion, shall allocate an aggregate amount not to exceed $5.0 million for
special bonuses to the employees of the Company or its Subsidiaries. The special
bonuses shall be paid out to each employee designated to participate in the
Special Bonus Plan as set forth on Schedule 6.1(e) (each, a "Participant") as to
2/3rds of the Participant's total special bonus on the three (3) month
anniversary of the Effective Time and as to the remaining 1/3rd of the total
special bonus on the six (6) month anniversary of the Effective Time. Such
payments shall be made whether or not the Participant is an employee of the
Company as of the applicable payments dates, unless the Participant's employment
with the Company (or, if applicable, the Surviving Company) has terminated prior
to the applicable payment date either (i) for "cause" (as defined in such
Participant's employment agreement, severance agreement or offer letter or if
the Participant does not have an employment agreement, severance agreement or
offer letter that defines "cause", the Company's 2000 Long Term Incentive Plan
as of immediately prior to the Effective Time) or (ii) the Participant
voluntarily terminates Participant's employment, except where the Participant
terminates employment for "Good Reason" or as a result of a "Constructive
Termination" (as defined in such Participant's employment agreement, severance
agreement or offer letter or if the Participant does not have an employment
agreement, severance agreement or offer letter that defines "Good Reason" or
"Constructive Termination," the Company's 2000 Long Term Incentive Plan as of
the date of this Agreement).

     (f) Except as provided in this Section 6.1, nothing in this Agreement shall
limit or restrict the right of Parent or any of its Subsidiaries to modify,
amend, terminate or establish employee benefit plans or arrangements, in whole
or in part, at any time after the Effective Time.

                                       38


     (g) No provision of this Section 6.1 shall create any third party
beneficiary rights in any Continuing Employee or any current or former director
or consultant of the Company or its Subsidiaries located in the United States in
respect of continued employment (or resumed employment) or any other matter.

     Section 6.2.  Indemnification Continuation.

     (a) For purposes of this Section 6.2, (i) "Indemnified Person" shall mean
any person who is now, or has been at any time prior to the Effective Time, an
officer or director of the Company or who was serving at the request of the
Company as an officer or director of another corporation, joint venture or other
enterprise, and can provide evidence thereof to Parent acceptable to Parent in
its sole discretion (which such discretion shall be reasonably applied) and (ii)
"Proceeding" shall mean any claim, action, suit, proceeding or investigation,
whether or not such claim, proceeding or investigation results in a formal civil
or criminal litigation or regulatory action.

     (b) From and after the Effective Time, Parent shall, or Parent shall cause
the Surviving Company to, provide indemnification (including, but not limited
to, attorneys' fees and other defense costs) to each Indemnified Person to the
same extent and under similar conditions and procedures as such Indemnified
Person is entitled on the date hereof, under the Company Organizational
Documents, in connection with any Proceeding based directly or indirectly (in
whole or in part) on, or arising directly or indirectly (in whole or in part)
out of, the fact that such Indemnified Person is or was an officer or director
of the Company, or is or was serving at the request of the Company as an officer
or director of another corporation, joint venture or other enterprise or general
partner of any partnership or a trustee of any trust, whether pertaining to any
matter arising before or after the Effective Time (including, but not limited
to, any acts or omissions in connection with this Agreement and the consummation
of the transactions contemplated hereby). Any right of indemnification of an
Indemnified Person pursuant to this Section 6.2(b) shall not be amended,
repealed or otherwise modified at any time in a manner that would adversely
affect the rights of such Indemnified Person as provided herein.

     (c) Parent shall cause the Surviving Company to, and the Surviving Company
shall, maintain in effect for six years from the Effective Time the Company's
current directors' and officers' liability insurance policies covering acts or
omissions occurring at or prior to the Effective Time with respect to
Indemnified Persons ("D&O Insurance") (provided that the Surviving Company may
substitute therefor policies with reputable carriers of at least the same
coverage containing terms and conditions that are not materially less favorable
to the Indemnified Persons); provided, however, that in no event shall the
Surviving Company be required to expend pursuant to this Section 6.2(c) more
than an amount per year equal to 200% of current annual premiums paid by the
Company for such insurance. In the event that, but for the proviso to the
immediately preceding sentence, the Surviving Company would be required to
expend more than 200% of current annual premiums, the Surviving Company shall
obtain the maximum amount of such insurance obtainable by payment of annual
premiums equal to 200% of current annual premiums. In lieu of the foregoing, the
Company may purchase, prior to the Effective Time, a six-year "tail" prepaid
officers' and directors' liability insurance policy in respect of acts or
omissions occurring prior to the Effective Time covering each such Indemnified
Person.

                                       39


     (d) The provisions of this Section 6.2 shall survive the consummation of
the Merger for a period of six years and are expressly intended to benefit each
of the Indemnified Persons and their respective heirs and representatives;
provided, however, that in the event that any claim or claims for
indemnification set forth in Section 6.2 are asserted or made within such
six-year period, all rights to indemnification in respect of any such claim or
claims shall continue until disposition of any and all such claims. If Parent
and/or Surviving Company, or any of their respective successors or assigns (i)
consolidates with or merges into any other Person, or (ii) transfers or conveys
all or substantially all of their businesses or assets to any other Person,
then, in each such case, to the extent necessary, a proper provision shall be
made so that the successors and assigns of Parent and/or Surviving Company, as
the case may be, shall assume the obligations of Parent and Surviving Company
set forth in this Section 6.2.

     Section 6.3.  Notice of Breach. From and after the date hereof and
until the earlier to occur of the Closing Date or the termination of this
Agreement pursuant to Article IX hereof, Parent shall promptly give written
notice with particularity upon having knowledge of any matter that may
constitute a breach by Parent of any representation, warranty, agreement or
covenant contained in this Agreement.

                                  ARTICLE VII.

                      ADDITIONAL COVENANTS OF THE PARTIES.

     Section 7.1.  Preparation of Proxy Statement and Registration
Statement; Company Stockholders Meeting.

     (a) As promptly as practicable, the Company shall prepare and file the
Proxy Statement with the SEC, and Parent shall prepare and file the Registration
Statement (in which the Proxy Statement will be included) with the SEC. Parent
and the Company shall use their reasonable best efforts to cause the
Registration Statement to become effective under the Securities Act as soon
after such filing as practicable and to keep the Registration Statement
effective as long as is necessary to consummate the Merger. The Proxy Statement
shall include the recommendation of the Board of Directors of the Company in
favor of approval and adoption of this Agreement and the Merger, except to the
extent the Board of Directors of the Company shall have withdrawn or modified
its approval or recommendation of this Agreement to the extent such action is
permitted by Section 7.5. The Company shall use its reasonable best efforts to
cause the Proxy Statement to be mailed to its stockholders as promptly as
practicable after the Registration Statement becomes effective. The parties
shall promptly provide copies, consult with each other and prepare written
responses with respect to any written comments received from the SEC with
respect to the Proxy Statement and the Registration Statement and advise one
another of any oral comments received from the SEC. The Registration Statement
and the Proxy Statement shall comply as to form in all material respects with
the rules and regulations promulgated by the SEC under the Securities Act and
the Exchange Act, respectively.

     (b) Parent and the Company shall make all necessary filings with respect to
the Merger and the transactions contemplated thereby under the Securities Act
and the Exchange Act and applicable "blue sky" laws and the rules and
regulations thereunder. Each party will advise the other, promptly after it
receives notice thereof, of the time when the Registration

                                       40


Statement has become effective or any supplement or amendment has been filed,
the issuance of any stop order, the suspension of the qualification of the
Parent Common Stock issuable in connection with the Merger for offering or sale
in any jurisdiction, or any request by the SEC for amendment of the Proxy
Statement or the Registration Statement or comments thereon and responses
thereto or requests by the SEC for additional information. No amendment or
supplement to the Proxy Statement or the Registration Statement shall be filed
without the approval of both parties hereto, which approval shall not be
unreasonably withheld, conditioned or delayed. If at any time prior to the
Effective Time, any information relating to Parent or the Company, or any of
their respective Affiliates, officers or directors, should be discovered by
Parent or the Company that should be set forth in an amendment or supplement to
the Registration Statement or the Proxy Statement, so that such documents would
not include any misstatement of a material fact or omit to state any material
fact necessary to make the statements therein, in light of the circumstances
under which they were made, not misleading, the party which discovers such
information shall promptly notify the other parties hereto and an appropriate
amendment or supplement describing such information shall be promptly filed with
the SEC and, to the extent required by law, disseminated to the stockholders of
the Company.

     (c) The Company shall cause the Company Stockholders Meeting to be duly
called and held as soon as reasonably practicable for the purpose of obtaining
the Required Company Vote. In connection with such meeting, the Company will (i)
subject to Section 7.5(b), use its commercially reasonable best efforts to
obtain the Required Company Vote and (ii) otherwise comply with all legal
requirements applicable to such meeting.

     Section 7.2.  Access to Information.

     Upon reasonable notice, the Company shall (and shall cause its Subsidiaries
to) afford to Parent and its representatives reasonable access during normal
business hours, during the period prior to the Effective Time, to all its
officers, employees, properties, offices, plants and other facilities and to all
books and records and, during such period, the Company shall (and shall cause
its Subsidiaries to) furnish promptly to Parent and its representatives,
consistent with its legal obligations, all other information concerning its
business, properties and personnel as Parent may reasonably request; provided,
however, that the Company may restrict the foregoing access to the extent that,
in the Company's reasonable judgment, (i) providing such access would result in
the disclosure of any trade secrets of third parties or violate any of its
obligations with respect to confidentiality if the Company shall have used all
reasonable efforts to obtain the consent of such third party to such access, or
(ii) any law, treaty, rule or regulation of any Governmental Entity applicable
to the Company requires the Company or its Subsidiaries to preclude Parent and
its representatives from gaining access to any properties or information. Parent
will hold any such information that is non-public in confidence to the extent
required by, and in accordance with, the provisions of that certain
Confidentiality Agreement, dated December 8, 2003 (the "Confidentiality
Agreement"), between the Company and Parent.

     Section 7.3.  HSR Act and Regulatory Matters.

     (a) Subject to the terms and conditions of this Agreement, each party will
use its commercially reasonable efforts to take, or cause to be taken, all
actions and to do, or cause to be done, all things necessary, proper or
advisable under applicable laws and regulations to

                                       41


consummate the Merger and the other transactions contemplated by this Agreement
as soon as practicable after the date hereof. In furtherance and not in
limitation of the foregoing, each party hereto agrees to make an appropriate
filing of a Notification and Report Form pursuant to the HSR Act with respect to
the transactions contemplated hereby as promptly as practicable, and in any
event within ten (10) Business Days after the execution of this Agreement, and
to supply as promptly as practicable any additional information and documentary
material that may be requested pursuant to the HSR Act and to take all other
actions necessary to cause the expiration or termination of the applicable
waiting periods under the HSR Act as soon as practicable.

     (b) Each of Parent and the Company shall, in connection with the efforts
referenced in Section 7.3(a) to obtain all requisite approvals and
authorizations for the transactions contemplated by this Agreement under the HSR
Act, the FCC Act or any other Regulatory Law (as defined below), use its
commercially reasonable best efforts to (i) cooperate in all respects with each
other in connection with any filing or submission and in connection with any
investigation or other inquiry, including any proceeding initiated by a private
party; (ii) promptly inform the other party of any communication received by
such party from, or given by such party to, the Antitrust Division of the
Department of Justice (the "DOJ"), the Federal Trade Commission (the "FTC") or
any other governmental authority and of any material communication received or
given in connection with any proceeding by a private party, in each case
regarding any of the transactions contemplated hereby, and (iii) permit the
other party to review any communication given by it to, and consult with each
other in advance of any meeting or conference with, the DOJ, the FTC, the FCC or
any such other governmental authority or, in connection with any proceeding by a
private party, with any other Person, and to the extent permitted by the DOJ,
the FTC, the FCC or such other applicable governmental authority or other
Person, give the other party the opportunity to attend and participate in such
meetings and conferences. For purposes of this Agreement, "Regulatory Law" means
the Sherman Act, as amended, the Clayton Act, as amended, the HSR Act, the
Federal Trade Commission Act, as amended, the Communications Act of 1934, as
amended by the Telecommunications Act of 1996, and all other federal, state and
foreign, if any, statutes, rules, regulations, orders, decrees, administrative
and judicial doctrines and other laws that are designed or intended to prohibit,
restrict or regulate actions having the purpose or effect of monopolization or
restraint of trade or lessening of competition through merger or acquisition. In
furtherance and not in limitation of the covenants of the parties contained in
Section 7.3(a) and this Section 7.3(b), each party hereto shall use its
reasonable best efforts to resolve objections, if any, as may be asserted with
respect to the transactions contemplated by this Agreement under any Regulatory
Law. Notwithstanding anything to the contrary contained in this Agreement,
Parent shall not be required to agree to any terms, conditions, modifications
with respect to obtaining any consents, permits, waivers, approvals,
authorizations or orders in connection with the Merger or the consummation of
the transactions contemplated by this Agreement that would result in, or would
reasonably likely to result in, either individually or in the aggregate, (i) a
material adverse effect on the business or operations of the Company and its
Subsidiaries, taken as a whole, or Parent and its Subsidiaries, taken as a whole
(assuming Parent is the size of the Company and its Subsidiaries, taken as a
whole), or (ii) Parent, the Company or any of their respective Subsidiaries
having to cease, sell or otherwise dispose of any assets or business (including
the requirement that any such assets or businesses be held separate).

                                       42


     (c) The Company shall use its commercially reasonable efforts to obtain all
consents, waivers, authorizations and approvals of all third parties, including
Governmental Entities, necessary, proper or advisable for the consummation of
the transactions contemplated by this Agreement; provided that, without the
prior written consent of Parent, the Company shall not incur any significant
expense or liability or agree to any significant modification to any contractual
arrangement to obtain such consents or certificates, and to provide any notices
to third parties required to be provided prior to the Effective Time.

     Section 7.4.  Reorganization.

     (a) The parties intend that the Merger or, if there is a Conversion Event,
the Merger and the Subsequent Merger, taken together, qualify as a
reorganization within the meaning of Section 368(a) of the Code and will report
it as such for federal, state and local income tax purposes. None of the parties
will knowingly take any action or fail to take any action, which action or
failure to act would cause the Merger to fail to qualify as a reorganization
within the meaning of Section 368(a) of the Code and the regulations promulgated
thereunder.

     (b) Each of the Company and Parent shall use its reasonable best efforts to
provide the officers' certificates and to obtain the opinions referred to in
Section 8.2(c) and Section 8.3(c) hereto, respectively.

     (c) Unless there is a Conversion Event, the parties agree that Merger Sub
shall be treated as a disregarded entity for U.S. federal income tax purposes
and agree not to take any action that would be inconsistent with such treatment.

     Section 7.5.  Acquisition Proposals.

     (a) None of the Company or any of its Subsidiaries shall (whether directly
or indirectly through Affiliates, directors, officers, representatives or other
intermediaries), nor shall (directly or indirectly) the Company authorize or
permit any of its or their officers, directors, representatives or other
intermediaries or Subsidiaries to, (i) solicit, initiate or take any action to
facilitate or encourage the submission of inquiries, proposals or offers from
any Person (other than Parent) relating to any Acquisition Proposal, or agree to
or endorse any Acquisition Proposal; (ii) enter into any agreement to (x)
facilitate or consummate, any Acquisition Proposal, (y) approve or endorse any
Acquisition Proposal or (z) in connection with any Acquisition Proposal, require
it to abandon, terminate or fail to consummate the Merger; (iii) enter into or
participate in any discussions or negotiations in connection with any
Acquisition Proposal or inquiry with respect to any Acquisition Proposal, or
furnish to any Person any information with respect to its business, properties
or assets in connection with any Acquisition Proposal or inquiry with respect to
any Acquisition Proposal; or (iv) agree to resolve or take any of the actions
prohibited by clause (i), (ii) or (iii) of this sentence. The Company shall
immediately cease, and cause its representatives and other intermediaries to
immediately cease, any and all existing activities, discussions or negotiations
with any parties conducted heretofore with respect to any of the foregoing and
shall demand the return or destruction of any information previously provided
with respect to such activities, discussion, or negotiations. For purposes of
this Section 7.5, the term "Person" means any person, corporation, entity or
"group," as defined in Section 13(d) of the Exchange Act, other than Parent or
any Subsidiaries of Parent.

                                       43


     "Acquisition Proposal" means any offer or proposal for a merger,
reorganization, recapitalization, consolidation, share exchange, business
combination or other similar transaction involving the Company or any of the
Subsidiaries or any proposal or offer to acquire, directly or indirectly,
securities representing more than 20% of the voting power of the Company or more
than 20% of the assets of the Company and the Subsidiaries taken as a whole,
other than the Merger contemplated by this Agreement.

     (b) Notwithstanding the foregoing, the Board of Directors of the Company,
directly or indirectly through representatives or other intermediaries, may (i)
comply with Rule 14d-9 and Rule 14e-2 promulgated under the Exchange Act with
regard to any Acquisition Proposal, so long as any such compliance rejects any
Acquisition Proposal and reaffirms its recommendation of the transactions
contemplated by this Agreement, except to the extent such action is permitted by
clause (iv) of this Section 7.5(b), (ii) engage in negotiations or discussions
with any Person that has made an unsolicited bona fide written Acquisition
Proposal not resulting from or arising out of a breach of Section 7.5(a), (iii)
furnish to such Person nonpublic information relating to the Company or any of
the Subsidiaries pursuant to a confidentiality and standstill agreement with
terms that are substantially similar to, and no less favorable in any material
respect to, the Company than those contained in the Confidentiality Agreement
and in the confidentiality agreement, dated August 5, 2002, between Parent and
the Company (it being understood that the standstill provision contained in such
confidentiality and standstill agreement may permit such Person to convey
confidentially an Acquisition Proposal to the Board of Directors of the Company
under circumstances in which the Company is permitted under this Section 7.5 to
participate in discussions regarding an Acquisition Proposal) and/or (iv) if
prior to the Company Stockholders Meeting, withdraw or modify or change in a
manner adverse to Parent its approval or recommendation of this Agreement or the
Merger; provided that the Board of Directors of the Company shall be permitted
to take an action described in the foregoing clauses (i), (ii), (iii) or (iv)
if, and only if, prior to taking such particular action, the Board of Directors
of the Company has determined in good faith by a majority vote that (x) such
Acquisition Proposal would result in, or would reasonably be expected to result
in, a Superior Proposal, in the case of any of the foregoing clauses (i), (ii)
or (iii), or constitutes a Superior Proposal, in the case of the foregoing
clause (iv), and (y) (in consultation with outside legal counsel) taking such
action would be reasonably likely to be required by its fiduciary duties under
the DGCL.

     "Superior Proposal" means any proposal (on its most recently amended or
modified terms, if amended or modified) made by a third party to enter into any
transaction involving an Acquisition Proposal that the Board of Directors of the
Company determines in its good faith judgment (after consultation with its
independent financial advisors and outside legal counsel) to be more favorable
to the Company's stockholders than this Agreement and the Merger, taking into
account all terms and conditions of such transaction (including any break-up
fees, expense reimbursement provision and financial terms, the anticipated
timing, conditions and prospects for completion of such transaction, including
the prospects for obtaining regulatory approvals and financing, and any third
party approvals), except that the reference to "20%" in the definition of
"Acquisition Proposal" shall be deemed to be a reference to "50%". Reference to
"this Agreement" and "the Merger" in this paragraph shall be deemed to include
any proposed alteration of the terms of this Agreement or the Merger that are
agreed to by Parent

                                       44


after it receives written notice from the Company pursuant to Section 7.5(d) of
the existence of, the identity of the Person making, and the terms and
conditions of, any Acquisition Proposal.

     (c) Notwithstanding anything in this Section 7.5 to the contrary, if, at
any time prior to the Company Stockholders Meeting, the Company's Board of
Directors determines (i) in good faith, in response to an Acquisition Proposal
that was unsolicited and that did not otherwise result from a breach of Section
7.5(a), that such proposal is a Superior Proposal, and (ii) (in consultation
with outside legal counsel) that taking such action would be reasonably likely
to be required by its fiduciary duties under the DGCL, the Company or its Board
of Directors may, subject to complying with Section 9.2(c), accept such Superior
Proposal and withdraw, modify or amend its recommendation of the Merger;
provided, however, that prior to any such withdrawal, modification or amendment
to the recommendation of the Company's Board of Directors, the Company shall
have given Parent five (5) Business Days' written notice (it being understood
and agreed that any amendment to the amount or form of consideration of the
Superior Proposal shall require a new notice and a new five (5) Business Day
period) advising Parent that the Company's Board of Directors intends to cause
the Company to accept such Superior Proposal, specifying the material terms and
conditions of the Superior Proposal and that the Company shall, during such five
(5) Business Day period, negotiate in good faith with Parent to make such
adjustments to the Merger Consideration and other terms and conditions of this
Agreement such that such Acquisition Proposal would no longer constitute a
Superior Proposal.

     (d) The Company shall notify Parent promptly (but in any event within 24
hours) after receipt or occurrence of (i) any Acquisition Proposal, (ii) any
request for information with respect to any Acquisition Proposal, (iii) any
inquiry, proposal, discussions or negotiation with respect to any Acquisition
Proposal, and (iv) the material terms and conditions of any such Acquisition
Proposal, request for information, inquiry, proposal, discussion or negotiation
and the identity of the Person making any such Acquisition Proposal, request for
information, inquiry or proposal or with whom discussions or negotiations are
taking place. In addition, the Company shall promptly (but in any event within
24 hours) after the receipt thereof, provide to Parent copies of any written
documentation material to understanding such Acquisition Proposal, request for
information, inquiry, proposal, discussion or negotiation ("Other Acquisition
Documentation") which is received by the Company from the Person (or from any
representatives or agents of such Person) making such Acquisition Proposal,
request for information, inquiry or proposal or with whom such discussions or
negotiations are taking place. The Company shall not, and shall cause each of
its Subsidiaries not to, terminate, waive, amend or modify any provision of any
existing standstill or confidentiality agreement to which it or any of its
Subsidiaries is a party, and the Company shall, and shall cause its Subsidiaries
to, enforce the provisions of any such agreement; provided, however, that, the
Company may waive any such provision in response to an Acquisition Proposal to
the Board of Directors of the Company made confidentially under circumstances in
which the Company is permitted under this Section 7.5 to participate in
discussions regarding an Acquisition Proposal, but only to the extent necessary
to allow it to respond to such Acquisition Proposal as permitted under this
Section 7.5. The Company shall keep Parent fully informed of the status and
details (including any amendments or proposed amendments) of any such
Acquisition Proposal or request for information and keep Parent fully informed
as to the material details of any information requested of or provided by the
Company and as to the material details of all discussions or

                                       45


negotiations with respect to any such Acquisition Proposal, request for
information, inquiry or proposal and shall provide to Parent within one Business
Day after receipt thereof all copies of any additional Other Acquisition
Documentation received by the Company from the Person (or from any
representatives or agents of such Person) making such Acquisition Proposal,
request for information, inquiry or proposal or with whom such discussions or
negotiations are taking place. The Company shall promptly provide to Parent any
non-public information concerning the Company provided to any other Person in
connection with any Acquisition Proposal that was not previously provided to
Parent. Any such non-public information shall be held by Parent subject to the
terms of the Confidentiality Agreement. The Board of Directors of the Company
shall promptly consider in good faith (in consultation with its outside legal
counsel and financial advisors) any proposed alteration of the terms of this
Agreement or the Merger proposed by Parent in response to any Acquisition
Proposal.

     Section 7.6.  Stockholder Litigation. The Company shall keep Parent
informed of, and cooperate with Parent in connection with, any stockholder
litigation or claim against the Company and/or its directors or officers
relating to the Merger or the other transactions contemplated by this Agreement;
provided, however, that no settlement in connection with such stockholder
litigation shall be agreed to without Parent's prior written consent, which
consent shall not be unreasonably withheld, conditioned or delayed.

     Section 7.7.  Maintenance of Insurance. The Company will use reasonable
best efforts to maintain in full force and effect through the Closing Date all
material insurance policies applicable to the Company and its Subsidiaries and
their respective properties and assets in effect on the date hereof. If and as
requested by Parent, the Company will use commercially reasonable best efforts
to cause the Company's insurers to waive any provisions in such insurance
policies that would allow the insurer to terminate or adversely modify coverage
upon consummation of the Merger.

     Section 7.8.  Public Announcements. Each of the Company, Parent and
Merger Sub agrees that no public release or announcement concerning the
transactions contemplated hereby shall be issued by any party without the prior
written consent of the Company and Parent (which consent shall not be
unreasonably withheld, conditioned or delayed), except as such release or
announcement may be required by law or the rules or regulations of any
applicable United States securities exchange, in which case the party required
to make the release or announcement shall use its reasonable best efforts to
allow each other party reasonable time to comment on such release or
announcement in advance of such issuance, it being understood that the final
form and content of any such release or announcement, to the extent so required,
shall be at the final discretion of the disclosing party.

     Section 7.9.  No Shareholder Rights Plan. From the date hereof through
the earlier of termination of this Agreement and the Effective Time, the Company
will not adopt, approve, or agree to adopt, a shareholder rights plan.

     Section 7.10.  Stock Exchange Listing. Parent shall use its commercially
reasonable efforts to cause the shares of Parent Common Stock to be issued in
connection with the Merger to be approved for quotation on Nasdaq, subject to
official notice of issuance.

                                       46

Merger illegal or otherwise prohibiting consummation of the Merger; provided,
however, that the provisions of this Section 8.1(b) shall not be available to

perform constitutes a breach of this Agreement;

     (c) By either the Company or Parent if any Governmental Entity shall have
issued an order, decree or ruling or taken any other action permanently

     (d) By either the Company or Parent if the approval by the stockholders of
the Company required for the consummation of the Merger shall not have been

of the failure to obtain the Required Company Vote at the Company Stockholders
Meeting (or any adjournment or postponement thereof);

the Company has complied with Section 9.2(c);

     (g) By the Company if there shall have been a breach of any representation,
warranty, covenant or agreement on the part of Parent or Merger Sub contained in
this Agreement such that the conditions set forth in Sections 8.3(a) or 8.3(b)
would not be satisfied and (A) such breach is not reasonably capable of being
cured or (B) in the case of a breach of a covenant or agreement, if such breach
is reasonably capable of being cured, such breach shall not have been cured
prior to the earlier of (I) 30 days following notice of such breach and (II) the

Agreement such that the conditions set forth in Sections 8.2(a) or 8.2(b) would

this Agreement pursuant to this Section 9.1(h) if Parent or Merger Sub is then
in material breach of any of its representations, warranties, covenants or

Parent as provided in Section 9.1, this Agreement shall forthwith become void
and there shall be no liability or obligation on the part of Parent or the
Company or their respective officers or directors except with respect to this

not relieve any party from any liability for any willful breach of any covenant
or agreement or willful breach of any representation or warranty in this
Agreement occurring prior to termination.

                                       50

immediately available funds to an account designated by Parent.

     (g) The Company acknowledges that the agreements contained in this Section

are not a penalty, and that, without these agreements, Parent would not enter
into this Agreement. If the Company fails to pay promptly the fee due pursuant

costs and expenses (including legal fees and expenses) in connection with any
action, including the filing of any lawsuit or other legal action, taken to
