ITEM 5.  OTHER EVENTS

Agreement to acquire US Xchange, Inc.

         On May 14, 2000, Choice One Communications Inc. (the "Company") entered
into an Agreement and Plan of Merger (the "Merger Agreement") with US Xchange,
Inc., a Delaware corporation ("US Xchange"), and the stockholder of US Xchange,
pursuant to which US Xchange will be merged with and into a newly formed wholly
owned subsidiary of the Company (the "Merger"). As a result of the Merger, the
separate corporate existence of US Xchange shall cease and the Company's
subsidiary shall continue as the surviving corporation and each share of US
Xchange's common stock will be converted into the right to receive cash and
shares of the Company's common stock. The amount of cash and the number of
shares of the Company's common stock into which each share of US Xchange's
common stock will be converted will be determined immediately prior to
consummation of the Merger in accordance with formulas specified in the Merger
Agreement. The Company estimates that it will be required to issue approximately
7.0 million shares of its common stock and to pay approximately $311 million in
net cash pursuant to the Merger, subject to adjustment. The above-referenced
cash payment includes approximately $279.2 million in US Xchange debt, together
with associated premiums, which will be paid off upon the consummation of the
Merger. The Company has agreed to provide certain registration rights to the
holders of the shares of its common stock to be issued in the Merger for the
registration of such shares under the Securities Act of 1933.

         Consummation of the Merger is subject to the satisfaction of certain
conditions, including (i) the Company obtaining financing on terms not
materially less favorable to the Company than those set forth in the executed
commitment letters received by the Company prior to the execution of the Merger
Agreement, (ii) the redemption of at least 80% of the outstanding principal
amount of the 15% Senior Notes due July 1, 2008 of US Xchange, L.L.C., having
properly authorized and approved an amendment to the Indenture, to take effect
on the redemption date, providing for the deletion of certain covenants and
other provisions thereof specified by the Company, (iii) the modification of
certain agreements relating to the operations of US Xchange, (iv) compliance
with all applicable provisions of the Hart-Scott-Rodino Antitrust Improvements
Act of 1976 and the expiration of all applicable waiting periods thereunder, (v)
receipt of specified regulatory approvals and (vi) certain other customary
conditions. Both the Company and US Xchange may terminate the Merger Agreement
if the Merger has not been consummated by November 14, 2000.

         In connection with the execution of the Merger Agreement, the Company
entered into a credit facility with US Xchange Finance Company, L.L.C. ("US
Xchange Finance Company"), a subsidiary of US Xchange, pursuant to which the
Company agreed to lend to US Xchange Finance Company up to $25 million on a
secured basis. The amount of such loans which was used to fund operating losses
of US Xchange and its subsidiaries will cause a reduction in the number of
shares of the Company's common stock to be issued at the closing of the Merger.

         The foregoing descriptions of the Merger Agreement and the transactions
contemplated thereby are intended to be a general summary and do not purport to
be complete.

         Attached as Exhibit 99.1 is a press release issued by the Company and
US Xchange, dated May 15, 2000, which is incorporated by reference herein.

CHOICE ONE SIGNS MERGER AGREEMENT WITH US XCHANGE; CHOICE ONE ALSO ANNOUNCES
$550 MILLION IN NEW FINANCING COMMITMENTS

o    MERGER CONSIDERATION INCLUDES APPROXIMATELY $311 MILLION IN NET CASH, PLUS
     7 MILLION SHARES OF CHOICE ONE STOCK, SUBJECT TO CLOSING ADJUSTMENTS
o    SIGNIFICANTLY ENLARGES CHOICE ONE'S TERRITORY; ACCELERATES EXPANSION OF
     ADDRESSABLE MARKET
o    ADDITIONAL FINANCING COMMITMENTS, INCLUDING $200 MILLION IN PREFERRED
     EQUITY, $200 MILLION IN ADDITIONAL SENIOR SECURED CREDIT AND $150 MILLION
     BRIDGE FACILITY FULLY FUND MERGER AND EXPANDED BUSINESS PLAN

Rochester, New York & Grand Rapids, Michigan - May 15, 2000 -- Choice One
Communications (NASDAQ: CWON), an Integrated Communications Provider offering
telecommunications services to small and medium-sized businesses in the
Northeast, announced today it has signed a definitive merger agreement with US
Xchange, a privately-held facility-based CLEC headquartered in Grand Rapids,
Michigan.

Founded in 1997, US Xchange offers a full suite of local and long distance voice
services to business and residential customers in second and third tier markets
located in Illinois, Indiana, Michigan and Wisconsin. With a principal focus
toward small and medium sized businesses, US Xchange currently serves
approximately 17,000 business and residential clients and has an installed base
of nearly 60,000 access lines. Based on unaudited first quarter 2000 results, US
Xchange has an annualized revenue run-rate of approximately $38 million. At
March 31, 2000, US Xchange had approximately $136 million in net property, plant
and equipment (without adjusting for fiber assets to be retained by an affiliate
of US Xchange) and a total of 476 colleagues.

                                    --MORE--

"This merger effectively doubles the size of our company and is an excellent
strategic fit that significantly accelerates our expansion into contiguous
markets," said Steve Dubnik, chairman and CEO of Choice One. "Choice One and US
Xchange share similar market philosophies, with a focus on small and medium
sized businesses in second and third tier markets, and our network and operating
systems are highly compatible. Importantly, this transaction adds many
experienced and knowledgeable telecommunications professionals to support the
combined companies' growth. Our recently announced first quarter results clearly
indicate we are executing on all facets of our business plan. We are excited
about this opportunity to rapidly extend the reach of our successes into new
markets through this merger." On May 8, Choice One reported first quarter
results exceeding analyst expectations for line growth, revenue and collocations
in service.

US Xchange's network is comprised of nine Lucent 5ESS switches, four Lucent
remote switching devices, 48 collocations and a 13 node data network. US Xchange
also has a network operations center (NOC) that provides after-hours alarm
surveillance and dispatching. The network infrastructure and many of US
Xchange's OSS elements, including their MetaSolv facility/order management
system, are both scalable and consistent with the technologies deployed by
Choice One. US Xchange's switching platforms are connected to the company's
soon-to-be-completed intra- and inter-city fiber network, which will be retained
by an affiliate of US Xchange. Prior to closing, Choice One and US Xchange will
finalize an agreement granting Choice One fiber access under a 20-year
indefeasible right to use (IRU) for no additional payments.

"With its extensive data network and growing base of business clients, US
Xchange is well positioned to market Choice One's suite of integrated data and
voice services. We believe this will result in substantial incremental revenue
growth for the combined companies in 2001 and beyond," stated Dubnik. "With a
contiguous service area that now extends from Wisconsin to Massachusetts, we are
well positioned to be the leading provider of voice and data communications in
second and third tier markets in the Northeast quadrant of the United States."

On a pro forma basis, the combined companies had $65 million in annualized first
quarter 2000 revenue. At March 31, 2000, the combined companies had
approximately $195 million in net property, plant and equipment, 226
collocations, more than 93,000 lines in service and nearly 1,000 total
colleagues. The combined companies expect to have nearly 4.5 million addressable
business lines via over 400 collocations in 26 markets by the end of this year.

"We are excited to join forces with Choice One--this transaction is a win for
all US Xchange colleagues and clients," commented Richard Postma, chairman and
CEO of US Xchange. "This combination will allow us to introduce new services to
our clients, including DSL and web services that complement our existing voice
services offerings. Choice One's access to capital will enable us to expand our
addressable market by making aggressive investments in our network collocations.
And most importantly, US Xchange colleagues will have exciting growth
opportunities as this new organization comes together." Mr. Postma is expected
to join Choice One's Board of Directors upon completion of the merger.

The companies expect to begin work immediately on transition plans to bring the
two organizations together. After closing, US Xchange plans to market products
and services under the name "US Xchange, A Choice One Communications Company".

SUMMARY OF TERMS OF THE MERGER AGREEMENT

The transaction has been approved by the Boards of Directors of US Xchange and
Choice One, by the sole shareholder of US Xchange and conditionally approved by
a majority of Choice One shareholders. Choice One was advised in the transaction
by UBS Warburg and First Union; US Xchange was advised by Morgan Stanley. Terms
of the agreement include:

o    Choice One will purchase the stock of US Xchange for approximately $311
     million in net cash and 7 million shares of newly issued Choice One common
     stock, subject to certain closing adjustments
o    Choice One does not expect to assume any US Xchange debt
o    Based on last Friday's closing price of $29.50 per share, the transaction
     is valued at approximately $518 million
o    Choice One will receive access to US Xchange's fiber via a 20-year IRU

The transaction is subject to certain conditions, including Hart-Scott-Rodino
clearance and other regulatory approvals. Additionally, US Xchange must
successfully cause bondholders to tender at least 80% of its high yield public
debt. As of Friday's close of business, holders of 100% of US Xchange's bonds
have agreed to tender their bonds. The transaction is expected to close before
the end of this year.

ADDITIONAL FINANCING COMMITMENTS

In connection with this agreement, Choice One announced that $550 million in
additional financing commitments have been secured to fund the transaction and
continued expansion of Choice One's business plan. These commitments are
expected to close coincident with the closing of the merger. The three
components of the financing package are:

o    $200 million in Series A Senior Cumulative Preferred stock. This
     non-convertible preferred stock has a 12-year maturity and provides for
     dividends of 14% payable in kind (PIK). The preferred shares will be placed
     with Morgan Stanley Dean Witter Capital Partners. In connection with the
     purchase of the preferred stock, the company will grant the purchaser
     warrants for 4.25% of the company's pro forma fully diluted common stock.
     The purchaser of the preferred stock and its affiliates currently own
     nearly 35% of Choice One's common stock.

o    $200 million in additional senior secured credit; Choice One's existing
     $150 million credit facility is to be replaced by a $350 million facility
     with similar terms and conditions. Importantly, the key lenders in the
     expanded facility, led by First Union Bank, were initial financial partners
     in Choice One's business plan.

o    $150 million senior unsecured bridge facility. Choice One plans to seek
     alternative permanent financing before the bridge facility is funded. If
     funded, the bridge notes will be placed with Morgan Stanley Senior Funding,
     Inc. and will have a term of up to one year. Upon maturity, the bridge
     facility may be replaced by a callable 9-year rollover facility.

                                    --MORE--
<PAGE>

Commenting on these financing commitments, Dubnik said, "Capital is a strategic
asset and our ability to secure this kind of financing from high-quality
partners is a testament to all that we have accomplished. It also speaks volumes
to the potential of our business plan going forward and we are proud that our
existing financial sponsors have "re-committed" with a financing structure that
is unique to a company like ours." Dubnik noted that the additional financing is
expected to provide Choice One with the capital necessary to complete the merger
with US Xchange, to expand US Xchange's collocation footprint, to deploy DSL
capability throughout the US Xchange markets and to fully fund Choice One's
existing 20-city business plan. "When this is completed, Choice One will have
over $700 million in total funding available and a very strong balance sheet."

"This transaction represents a significant step for Choice One's strategy of
providing data and voice services to second and third tier markets," said John
B. Ehrenkranz, Managing Director of Morgan Stanley Dean Witter Private Equity.
"We are very excited about our partnership with Choice One's impressive
management team and the company's strong industry position. As one of the
largest and most successful private equity investors in the telecommunications
industry, with over $5 billion of investment gains in companies including
Equant, Allegiance Telecom and First Telecom, we believe that Choice One is
representative of our philosophy of partnering with proven management teams to
build leading companies in this sector."

Completion of the financing is subject to certain conditions, including closing
of the proposed merger and other customary conditions.

         Upon the terms and subject to the conditions set forth in Article VII,

referred to as the "Closing Date."

         SECTION 1.03.  Effect of the Merger.

         At the Effective Time, the effect of the Merger shall be as provided in
the applicable provisions of Delaware Law. Without limiting the generality of

Acquiror Sub's certificate of incorporation shall be amended at the Effective
Time to read as follows: "The name of the corporation is US Xchange Inc."

         (b)      Unless otherwise determined by Acquiror prior to the Effective
Time, at the Effective Time the bylaws of Acquiror Sub shall continue unchanged
and shall be the bylaws of

qualified.

endorsed in blank in proper form for transfer and with all required stock
transfer stamps, if any, affixed;

         (c)      the certificates required to be delivered pursuant to Section

                   CONVERSION OF SECURITIES; FRACTIONAL SHARES

         SECTION 2.01.  Conversion of Securities.

         At the Effective Time, as provided in this Merger Agreement, by virtue
of the Merger and without any action on the part of Acquiror Sub, the Company or
the Company Stockholder:

<PAGE>
                                       -4-

         (a)      Conversion.

                  (i) Company Common Stock. Subject to the provisions of this
Section 2.01, each share of common stock, $.01 par value per share, of the
Company ("Company Common Stock") issued and outstanding immediately prior to the
Effective Time (other than any shares of Company Common Stock to be canceled
pursuant to Section 2.01(b)), shall be converted, subject to Section 2.02, into
the right to receive (A) the Common Stock Cash Amount (as defined in Article X),
and (B) one share of common stock, par value $.01 per share, of Acquiror
("Acquiror Common Stock") multiplied by the Common Stock Exchange Ratio (as
defined in Article X) (the "Stock Consideration" and, together with the Common
Stock Cash Amount, the "Merger Consideration").

                  At the Effective Time, all such shares of Company Common Stock
shall no longer be outstanding and shall automatically be canceled and retired
and shall cease to exist, and each certificate previously representing any such
shares shall thereafter represent the right to receive the Merger Consideration.
No fractional share of Acquiror Common Stock shall be issued, and, in lieu
thereof, a cash payment shall be made pursuant to Section 2.02 hereof.

                  (ii) Merger Consideration. If between the date of this Merger
Agreement and the Effective Time the outstanding shares of Acquiror Common Stock
or Company Common Stock shall have been changed into a different number of
shares or a different class, by reason of any stock dividend, subdivision,
reclassification, recapitalization, split, combination or exchange of shares,
the Merger Consideration shall be appropriately and correspondingly adjusted to
reflect such stock dividend, subdivision, reclassification, recapitalization,
split, combination or exchange of shares.

         (b)      Cancellation of Treasury Stock. Any shares of capital stock of
the Company held in the treasury of the Company and any shares of capital stock
of the Company owned by Acquiror or any direct or indirect wholly owned
subsidiary of Acquiror or of the Company immediately prior to the Effective Time
shall be canceled and extinguished without any conversion thereof and no payment
or distribution shall be made with respect thereto.

         (d)      Acquiror Sub Common Stock. Each share of common stock, par
value $.01 per share, of Acquiror Sub issued and outstanding immediately prior
to the Effective Time shall continue to be one issued and outstanding share of
common stock, par value $.01 per share, of the Surviving Corporation, which
shall continue to be held by Acquiror.

         SECTION 2.02.  Fractional Shares.

         No fractional shares of Acquiror Common Stock shall be issued upon
surrender for exchange of the certificate or certificates evidencing Company
Common Stock which immediately prior to the Effective Time represented
outstanding shares of Company Common Stock (the "Certificate"), and any such
fractional share interests will not entitle the owner thereof to vote or to any
rights of a stockholder of Acquiror, but in lieu thereof the Company Stockholder
who would otherwise be entitled to receive a fraction of a share of Acquiror
Common Stock, after aggregating all Certificates delivered by him, and rounding
down to the nearest whole share, shall receive an amount in cash equal to the
Price Per Share multiplied by

<PAGE>
                                      -5-

the fraction of a share of Acquiror Common Stock to which such holder would
otherwise be entitled. Such payment in lieu of fractional shares shall be paid
in immediately available funds by the Acquiror on the Closing Date.

         SECTION 2.03.  Stock Transfer Books.

         At the Effective Time, the stock transfer books of the Company shall be
closed and there shall be no further registration of transfers of shares of
capital stock of the Company thereafter on the records of the Company. From and
after the Effective Time, the Company Stockholder shall cease to have any rights
with respect to such shares of capital stock of the Company except as otherwise
provided herein or by Law.

                                   ARTICLE III

                  REPRESENTATIONS AND WARRANTIES OF THE COMPANY

         Except as specifically set forth in (x) the Disclosure Schedule
delivered by the Company to Acquiror prior to the execution and delivery of this
Merger Agreement (the "Company Disclosure Schedule") (the contents of which
Company Disclosure Schedule may be updated, corrected or otherwise modified by
the Company up to five (5) days prior to the Closing Date in accordance with

Merger Agreement to require a specific reference in the Company Disclosure
Schedule to the Section of this Merger Agreement to which each such disclosure
applies, (ii) no disclosure to be deemed to apply with respect to any Section to
which it does not expressly refer and (iii) the Company having the right to
cross-reference the sections of the Company Disclosure Schedule as appropriate
with respect to disclosures that are reasonably related) and (y) the Subsidiary
SEC Reports (as defined in Section 3.08) filed prior to the date hereof, the

good standing under Delaware Law, and has the requisite corporate power and
authority to own, operate and lease its Assets (as defined in Article X), to
carry on its business as currently conducted, to execute and deliver this Merger
Agreement and to carry out the transactions contemplated hereby. The Company is
duly qualified to conduct business as a foreign corporation and is in good
standing in Michigan and in each jurisdiction where the nature of its business
or the ownership or leasing of its properties makes such qualification necessary
other than where the failure to be so qualified would not have a Company
Material Adverse Effect.

         SECTION 3.02.  Subsidiaries.

         Except as set forth in Section 3.02 of the Company Disclosure Schedule,
the Company has no Subsidiaries (as defined in Article X) and neither the
Company nor any Subsidiary has

<PAGE>
                                      -6-


any equity investment or other interest in, nor has the Company or any
Subsidiary made advances or loans to (other than intra-company transactions
between or among the Company and any Subsidiary and other than for customary
credit extended to customers of the Company in the Ordinary Course of Business

sets forth (a) the authorized capital stock or other equity interests of each
Subsidiary and the percentage of the outstanding capital stock or other equity
interests of each Subsidiary owned by the Company. All of such shares of capital
stock or other equity interests of the Subsidiaries have been duly authorized

the Company free and clear of all Encumbrances (as defined in Article X) other

state or jurisdiction of organization (as listed in Section 3.02 of the Company
Disclosure Schedule), and has the requisite corporate or limited liability
company power and authority to own, operate and lease its Assets and to carry on
its business as currently conducted. Each Subsidiary is duly qualified to
conduct business as a foreign Person and is in good standing in each
jurisdiction where the nature of its business or the ownership or leasing of its
properties makes such qualification necessary, other than where the failure to
be so qualified would not have a Company Material Adverse Effect.

         SECTION 3.03.  Certificate of Incorporation and Bylaws.

         The Company has furnished to Acquiror a true and complete copy of (i)
the certificate of incorporation and (ii) the organizational documents of the

secretary.

         SECTION 3.04.  Capitalization.

         The authorized capital stock of the Company consists of 20,000 shares
of Company Common Stock, of which: (i) 1,000 shares are issued and outstanding,
all of which are duly authorized, validly issued, fully paid and nonassessable
and owned of record by the Company Stockholder; and (ii) no shares are held in
the treasury of the Company. Except as described in this Section 3.04 or in
Section 3.04 of the Company Disclosure Schedule, no other shares of capital
stock of the Company have been reserved for any purpose. There are no
outstanding securities convertible into or exchangeable for Company Common
Stock, any other securities of the Company, or any capital stock or other
securities of any of the Subsidiaries and no outstanding options, rights
(preemptive or otherwise), or warrants to purchase or to subscribe for any
shares of such stock or other securities of the Company or any of the
Subsidiaries. Except as set forth in Section 3.04 of the Company Disclosure
Schedule, there are no outstanding Agreements (as defined in Article X)
affecting or relating to the voting, issuance, purchase, redemption,
registration, repurchase or transfer of Company Common Stock, any other
securities of the Company, or any capital stock or other securities of any
Subsidiary, except as contemplated hereunder. Each of the outstanding shares of
Company Common Stock and of capital stock of, or other equity interests in, the
Subsidiaries was issued in compliance with all

<PAGE>
                                      -7-

applicable federal and state Laws concerning the issuance of securities. There
are no obligations, contingent or otherwise, of the Company or any Subsidiary to
provide funds to, make any investment (in the form of a loan, capital
contribution or otherwise) in, or provide any guarantee with respect to, any
Person other than the Company or its wholly owned Subsidiaries. There are no
Agreements pursuant to which any Person (other than the Company or its wholly
owned Subsidiaries) is or may be entitled to receive any of the revenues or
earnings, or any payment based thereon or calculated in accordance therewith, of
the Company or any Subsidiary.

         SECTION 3.05.  Authority; Binding Obligation.

         The execution and delivery by the Company of this Merger Agreement, the
execution and delivery by the Company and the Subsidiaries of all other
agreements, documents, certificates or other instruments contemplated hereby,
and the consummation by the Company and the Subsidiaries of the transactions
contemplated hereby and thereby, have been duly authorized by all necessary
corporate and shareholder action, and no other corporate or shareholder
proceedings on the part of the Company or the Subsidiaries are necessary to
authorize this Merger Agreement and the other agreements, documents,
certificates or other instruments contemplated hereby, or to consummate the
transactions contemplated hereby and thereby (other than, with respect to the
Merger, the filings and recordation of appropriate merger documents as required
by Delaware Law). This Merger Agreement has been duly executed and delivered by
the Company and, assuming the due authorization, execution and delivery by
Acquiror, Acquiror Sub and the Company Stockholder, constitutes a legal, valid
and binding obligation of the Company, enforceable in accordance with its terms,
except as such enforceability may be subject to the effects of any applicable
bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium or
similar Laws affecting creditors' rights generally and subject to the effects of
general equitable principles (whether considered in a proceeding in equity or at
law); provided, however, that the Merger will not become effective until
Articles of Merger reflecting the Merger are filed with the office of the
Secretary of State of the State of Delaware.

         SECTION 3.06.  No Conflict; Required Filings and Consents.

         (a)      The execution, delivery and performance by the Company of this

the Subsidiaries of all other agreements, documents, certificates or other
instruments contemplated hereby, the fulfillment of and compliance with the
respective terms and provisions hereof and thereof, and the consummation by the

applicable to the Company or any Subsidiary, or any of their respective Assets;
(iii) subject to obtaining the consents and approvals set forth in Section
3.06(b) of the Company Disclosure Schedule, conflict with, result in any breach
of, or constitute a default (or an event that with

<PAGE>
                                      -8-

notice or lapse of time or both would become a default) under any Agreement to
which the Company or any Subsidiary is a party or by which the Company or any
Subsidiary, or any of their respective Assets, may be bound; or (iv) except as
disclosed in Section 3.06(b) of the Company Disclosure Schedule, result in or
require the creation or imposition of, or result in the acceleration of, any
indebtedness or any Encumbrance of any nature upon, or with respect to, the
Company or any Subsidiary or any of the Assets now owned or hereafter acquired
by the Company or any Subsidiary; except for any such conflict or violation
described in clause (ii), any such conflict, breach or default described in
clause (iii), or any such creation, imposition or acceleration described in
clause (iv) that would not have a Company Material Adverse Effect and that would
not prevent the Company from consummating the Merger on a timely basis.

         (b)      Except as set forth in Section 3.06(b) of the Company
Disclosure Schedule and for non-material Agreements allowing the installation,
maintenance or operation of the Company's or its Subsidiaries' fiber optic

the execution, delivery, performance by the Company and the Subsidiaries of all
other agreements, documents, certificates or other instruments contemplated
hereby, the fulfillment of and compliance with the respective terms and
provisions hereof and thereof, and the consummation by the Company and the
Subsidiaries of the transactions contemplated hereby and thereby, do not and
will not: (i) require any consent, approval, authorization or permit of, or
filing with or notification to, any Person not party to this Merger Agreement,
except (A) pursuant to the applicable requirements, if any, of the HSR Act, the
Communications Act, applicable state utility Laws and applicable municipal
franchise Laws and Laws of other Governmental Entities, (B) the filing and
recordation of the Articles of Merger as required by Delaware Law, (C) as may be
necessary as a result of facts or circumstances related solely to Acquiror or
Acquiror Sub and (D) where the failure to obtain any consent, approval,
authorization or permit or to make any filing or notification otherwise required
to be disclosed hereunder would not have a Company Material Adverse Effect; or
(ii) result in or give rise to any penalty, forfeiture, Agreement termination,
right of termination, amendment or cancellation, or restriction on business
operations of Acquiror, the Company, the Surviving Corporation or any Subsidiary
that would have a Company Material Adverse Effect.

         SECTION 3.07.  Licenses; Compliance.

         (a)      Each of the Company and each Subsidiary is in possession of
all Licenses (as defined in Article X) necessary for the Company or any
Subsidiary to own, lease and operate its Assets or to carry on its business as
it is now being conducted (the "Company Licenses"), except where the failure to
possess, or the suspension or cancellation of, any such Company License would
not have a Company Material Adverse Effect. All Company Licenses that are FCC
(as defined in Article X), or state utilities Licenses or municipal franchises,
and all other Company Licenses the loss of which would have a Company Material
Adverse Effect, are listed in Section 3.07(a) of the Company Disclosure
Schedule. All Company Licenses are valid and in full force and effect through
the respective dates indicated in such Company Licenses, except for any such
invalidity or failure to be in full force and effect that would not have a
Company Material Adverse Effect, and no suspension, cancellation, complaint,
proceeding, order or investigation of or with respect to any Company License (or
operations thereunder) the loss of which would not have a Company Material
Adverse Effect is pending or, to the knowledge of

<PAGE>
                                      -9-

the Company or any Subsidiary, threatened. The Company has indicated in Section
3.07 of the Company Disclosure Schedule those Company Licenses which expire by
their terms within 12 months from the date of this Merger Agreement. Neither the
Company nor any Subsidiary is in violation of or default under any Company
License, except for any such violation or default that would not have a Company
Material Adverse Effect. Except as set forth in Section 3.07(a) of the Company
Disclosure Schedule, since March 1, 1999, neither the Company nor any Subsidiary
has received written or, to the knowledge of the Company or any Subsidiary, oral
notice from any Governmental Entity or any other Person of any allegation of any
such violation or default under a Company License that would have a Company
Material Adverse Effect.

         (b)      Neither the Company nor any Subsidiary is in violation of or
default under, nor has it breached, (i) any term or provision of its certificate
or articles of incorporation, bylaws, operating agreement or certificate or
articles of formation or (ii) any Agreement or restriction to which the Company
or any Subsidiary is a party or by which the Company or any Subsidiary, or any
of their respective Assets, is bound or affected, except for any such violation,
default or breach described in clause (ii) that would not have a Company
Material Adverse Effect. The Company and the Subsidiaries have complied and are
in full compliance with all Laws, except where the failure to so comply would
not have a Company Material Adverse Effect.

         (c)      All returns, reports, statements and other documents required
to be filed by the Company or any Subsidiary with any Governmental Entity have
been filed and complied with and are true, correct and complete in all material
respects (and any related fees required to be paid have been paid in full)
except where the failure to so file, comply or to so pay such fees would not
have a Company Material Adverse Effect. Except as would not have a Company
Material Adverse Effect and to the knowledge of the Company and the
Subsidiaries, all records of every type and nature relating to the Company
Licenses or the business, operations or Assets of the Company or any Subsidiary
have been maintained in all respects in accordance with good business practices
and the rules of any Governmental Entity and are maintained at the Company or
the appropriate Subsidiary.

         (d)      Except as provided in Section 3.07(a) of the Company
Disclosure Schedule, neither the Company nor any Subsidiary has any interest in
any License (including both any Company License and any License held by third
parties in which the Company or any Subsidiary has an interest, if any) the loss
of which would have a Company Material Adverse Effect and that is subject to
restrictions on assignment or transfer based on the circumstances under which
the License was granted (such as eligibility or auction rules), the status of
construction and operation (such as rules restricting resale for a certain
period after construction), or any other restrictions other than an ordinary
course requirement for prior approval of transactions such as the Merger
contemplated herein.

         (e)      Neither the Company nor any Subsidiary is aware of any fact or
circumstance related to them that would reasonably be expected to cause the
filing of any objection to any application for any Governmental consent required
hereunder, lead to any delay in processing such application, or require any
waiver of any Governmental rule, policy or other applicable Law.

         (a)      The Company has delivered to the Acquiror a true and complete
copy of an audited consolidated balance sheet of the Company and the
Subsidiaries as of the end of the fiscal year ended December 31, 1999 (the
"Audited Balance Sheet") and the related audited consolidated statements of

flows of the Company and the Subsidiaries for the one-month periods then ended
(the Unaudited Balance Sheets and such statements of income and cash flows are

with the Audited Statements, as the "Pre-Signing Financial Statements").

         (b)      The Pre-Signing Financial Statements, including, without
limitation, the notes thereto, (i) are complete and correct in all material
respects, (ii) have been prepared in accordance with the books and records of
the Company and the Subsidiaries, and (iii) present fairly, in all material

accordance with GAAP applied on a basis consistent with past practices of the
Company, except as noted thereon and subject to, in the case of the Unaudited

adjustments which were not material in amount. All changes in accounting methods
(for financial accounting purposes) made, agreed to, requested or required with
respect to the Company or any of the Subsidiaries since January 1, 2000 and
prior to the date hereof are reflected in the Pre-Signing Financial Statements.

         (c)      Except as set forth in Section 3.08(c) of the Company
Disclosure Schedule, US Xchange, L.L.C., a Michigan limited liability company
(the "Reporting Subsidiary") has filed with the SEC all forms, reports,
schedules, registration statements, definitive proxy statements, information
statements and other filings (the "Subsidiary SEC Reports") required to be filed
by it with the SEC since March 1, 1998. As of their respective dates, the
Subsidiary SEC Reports complied as to form in all material respects with the
requirements of the Exchange Act or the Securities Act, as the case may be, and
the rules and regulations of the SEC thereunder applicable to such Subsidiary
SEC Reports. As of their respective dates and as of the date any information
from such Subsidiary SEC Reports has been incorporated by reference, the
Subsidiary SEC Reports did not contain any untrue statement of a material fact
or omit to state a material fact required to be stated therein or necessary to
make the statements therein, in light of the circumstances under which they were
made, not misleading.

         SECTION 3.09.  Absence of Undisclosed Liabilities.

payable, for or with respect to the applicable period, and for which the Company
or any Subsidiary may be liable in its own right (including, without limitation,
by reason of being a member of the same affiliated group) or as a transferee of
the Assets of, or successor to, any Person.

         (b)      Neither the Company nor any Subsidiary, either in its own
right (including, without limitation, by reason of being a member of the same
affiliated group) or as a transferee, has or at the Closing Date will have any

matters is currently in force.

copies of all Company Tax Returns and all material written communications with
any Governmental Entity relating to any such Company Tax Returns or to any
deficiency or claim proposed or asserted, irrespective of the outcome of such
matter, but only to the extent such items relate to Tax years (i) which are
subject to an audit, investigation, examination or other proceeding currently
pending, or (ii) with respect to which the statute of limitations for the
assessment of Tax has not expired.

         (e)      Neither the Company nor any Subsidiary (i) is or has ever been
a member of an affiliated group of corporations filing consolidated federal

rules and regulations relating to the withholding of Taxes.

         (g)      The Company has had in effect a valid "S" election for federal
and state income tax purposes for a period commencing on the date of its
incorporation and at all times during this period through the Closing has been
taxable as an S corporation for federal income tax purposes and the Company has
also been fully recognized and taxable as an "S" Corporation (or similar entity
entitled to special tax treatment) by each state, locality or other jurisdiction
in which it conducts any business. No written claim has ever been made by a
Governmental Entity in which the Company does not file Company Tax Returns that
the Company may be subject to taxation by that jurisdiction.

         To the knowledge of Acquiror, neither Acquiror, Acquiror Sub nor any of

within the meaning of Section 368(a) or Section 368(a)(2)(D) of the Code.

         SECTION 4.12.  Compliance; Litigation.

         Neither Acquiror nor Acquiror Sub is aware of any fact or circumstance

nature required by GAAP to be reflected, or reserved against, in the Acquiror
Financial Statements and that are not so reflected, or reserved against, in the
Acquiror Financial Statements, except for those that may have been incurred
after January 1, 2000 in the Ordinary Course of Business and that are not
material in amount either individually or collectively.

         SECTION 4.14.  Intellectual Property.

Property of any third party.

         (b)      Except as would have an Acquiror Material Adverse Effect, no
claim has been asserted to Acquiror that the conduct of the business of Acquiror

Property in the continued operation of its respective business in accordance
with the terms of the license agreement governing such Acquiror Licensed

         (e)      To the Knowledge of the Acquiror and except as would not have
an Acquiror Material Adverse Effect, the Acquiror Owned Intellectual Property is
valid and enforceable, and has not been adjudged invalid or unenforceable in
whole or in part.

         (f)      To the Knowledge of Acquiror and except as would not have an

                                      -41-


         (a)      The Company shall, and shall cause its directors, officers,

such inquiries or to obtain a Competing Transaction, or agree to or endorse any

instruct and use its or their reasonable best efforts to cause the directors,
officers, employees, agents and representatives of the Company and the
Subsidiaries (including, without limitation, any investment banker, financial
advisor, attorney or accountant retained by the Company or any Subsidiary) not

promptly notify Acquiror if any such inquiries or proposals are received by the

respective directors, officers, employees, agents, investment bankers, financial
advisors, attorneys, accountants or other representatives, and the Company or
the Company Stockholder shall promptly inform Acquiror as to the material terms

delivered to Acquiror a copy of such inquiry or proposal, and the Company or the
Company Stockholder shall keep Acquiror informed, on a current basis, of the

contemplated by this Merger Agreement): (i) any merger, consolidation, share
exchange, business combination, or other similar transaction; (ii) any sale,
lease, exchange, mortgage, pledge, transfer or other disposition of ten percent

the right to acquire beneficial ownership of, ten percent (10%) or more of the
then outstanding shares of capital stock of the Company or any Subsidiary; or

                                      -42-


or propose to approve or recommend, any Competing Transaction or (ii) enter into
any Agreement with respect to any Competing Transaction.

         SECTION 5.06.  Confidentiality.

         Each of the parties hereto has disclosed and delivered and will
disclose and deliver to the other party certain information about its
properties, employees, finances, businesses and operations (such party when
disclosing such information being the "Disclosing Party" and such party when
receiving such information being the "Receiving Party"). All such information
furnished by the Disclosing Party or its Representatives (as defined below),
whether furnished before or after the date hereof, whether oral or written, and
regardless of the manner in which it is furnished, is referred to in this
Agreement as "Proprietary Information." Proprietary Information does not
include, however, information which (a) is or becomes generally available to the
public other than as a result of a disclosure by the Receiving Party or its
Representatives, (b) was available to the Receiving Party on a nonconfidential
basis prior to its disclosure by the Disclosing Party or its Representatives,
(c) becomes available to the Receiving Party on a nonconfidential basis from a
Person other than the Disclosing Party or its Representatives who is not
otherwise bound by a confidentiality agreement with the Disclosing Party or any
of its Representatives, or is otherwise not under an obligation to the
Disclosing Party or any of its Representatives not to transmit the information
to the Receiving Party or (d) which is disclosed in accordance with Section
6.05. As used in this Agreement, the term "Representative" means, as to any
Person, such Person's Affiliates and its and their directors, officers,
employees, agents, advisors (including, without limitation, financial advisors,
counsel and accountants) and controlling Persons.

                  (i) Subject to clause (ii) below, unless otherwise agreed to
in writing by the Disclosing Party, the Receiving Party agrees (a) except as
required by Law, to keep all Proprietary Information confidential and not to
disclose or reveal any Proprietary Information to any Person other than its
Representatives who are actively and directly participating in the consummation
of the transactions contemplated hereby or who otherwise need to know the
Proprietary Information in connection with the transactions contemplated hereby
and to cause those Persons to observe the terms of this Merger Agreement and (b)
not to use Proprietary Information for any purpose other than in connection with
the transactions contemplated hereby. The Receiving Party will be responsible
for any breach of the terms of this Section 5.06 by the Receiving Party or any
of its Representatives when acting in such capacity.

                  (ii) In the event that the Receiving Party is requested
pursuant to, or required by, Law or stock exchange rule or by legal process to
disclose any Proprietary Information or any other information concerning the
Disclosing Party, the Receiving Party agrees that it will provide the Disclosing
Party with prompt notice of such request or requirement in order to enable the
Disclosing Party to seek an appropriate protective order or other remedy, to
consult with the Receiving Party with respect to the Disclosing Party taking
steps to resist or narrow the scope of such request or legal process, or to
waive compliance, in whole or in part, with the terms of this Section 5.06. In
the event that no such protective order or other remedy is obtained or that the
Disclosing Party waives compliance with the terms of this Section 5.06 the
Receiving Party will furnish only that portion of any Proprietary Information
which the Receiving Party is



<PAGE>
                                      -43-

advised by counsel is legally required and will exercise all reasonable efforts
to obtain reliable assurance that confidential treatment will be accorded any
Proprietary Information.

                  (iii) If this Merger Agreement is terminated, each party will
promptly return to the other party all copies of Proprietary Information in its
possession or in the possession of any of its Representatives and will not
retain any copies or other reproductions in whole or in part of such material.
All other documents, memoranda, notes, summaries, analyses, extracts,
compilations, studies or other material whatsoever prepared by it or any of its
Representatives based on the Proprietary Information will be destroyed, and such
destruction will be certified in writing to the other party by an authorized
officer supervising such destruction. Any oral Proprietary Information will
continue to be the subject of this Section 5.06.

                  (iii) Without prejudice to the rights and remedies otherwise
available to each of the parties hereto, each such party shall be entitled to
equitable relief by way of injunction or otherwise if the other party or any of
its Representatives breaches or threatens to breach any of the provisions of
this Section 5.06.

                                   ARTICLE VI

                              ADDITIONAL AGREEMENTS

         SECTION 6.01.  Registration Rights.

         (a)      If on any occasion after the Exercise Date one or more of the
Holders of Registrable Securities having an aggregate proposed market price of
not less than $25,000,000 shall notify Acquiror in writing that he or they
intend to offer or cause to be offered for public sale all or any portion of his
or their Registrable Securities, Acquiror will notify all of the Holders of
Registrable Securities of its receipt of such notification from such Holder or
Holders. Upon the written request of any such Holder delivered to Acquiror
within 15 days after receipt from the Company of such notification, Acquiror
will use its best efforts to cause such of the Registrable Securities as may be
requested by any Holders (including the Holder or Holders giving the initial
notice of intent to register hereunder) to be registered under the Securities
Act within 90 days of the notification by the Holders, in accordance with the
terms of this Section 6.01(a); provided, however that unless such registration
becomes effective, the Holders of the Registrable Securities shall be entitled
to require an additional registration pursuant to this Section 6.01(a). All
expenses of such registration and offerings incurred by Acquiror (which shall in
no event include underwriting discounts or commissions attributable to the sale
of Registrable Securities), and the reasonable fees and expenses of one
independent counsel for the Holders shall be borne by Acquiror, provided,
however, that Acquiror shall have no liability for such expenses if such
registration does not become effective due solely to the action or failure to
act of any Holder requiring such registration. Notwithstanding any other
provision of this Section 6.01, with respect to any registration statement
filed, or to be filed, pursuant to this Section 6.01(a), if Acquiror shall
furnish to the Holders of Registrable Securities that have made such request a
certified resolution of Acquiror's Board of Directors stating that in the
Board's good faith judgment it would (because of the existence of, or in
anticipation of, any acquisition or other material event or transaction the
public disclosure of which at the time would be

<PAGE>
                                      -44-

materially prejudicial to Acquiror) be significantly disadvantageous (a
"Disadvantageous Condition") to Acquiror for such a registration statement to be
maintained effective, or to be filed and become effective, or for sales of
Registrable Securities under such registration statement to be permitted, or for
the disclosure thereunder to remain current, and setting forth in reasonable
detail the general reasons for such judgment, Acquiror shall be entitled to
cause such registration statement to be withdrawn and the effectiveness of such
registration statement terminated or such sales under such registration
statement to be prohibited, or, in the event no registration statement has yet
been filed, shall be entitled not to file any such registration statement, until
such Disadvantageous Condition no longer exists (written notice of which
Acquiror shall promptly deliver to such Holders) (any such time period during
which such registration statement is withdrawn, the effectiveness of such
registration statement is terminated, the filing of such registration statement
is delayed or any sales under such registration statement are prohibited is
referred to herein as the "Blackout Period"). Upon receipt of any such
certification of a Disadvantageous Condition, such Holders shall forthwith
discontinue use of the prospectus contained in such registration statement and,
if so directed by Acquiror, each such Holder will deliver to Acquiror all
copies, other than permanent file copies then in such Holder's possession, of
the prospectus then covering such Registrable Securities current at the time of
receipt of such notice; provided that, notwithstanding anything else contained
in this Agreement, (i) neither the filing nor the effectiveness of any such
registration statement may be delayed nor sales thereunder be prohibited for a
period in excess of 90 days due to the occurrence of any particular
Disadvantageous Condition and (ii) in connection with any registration request
under Section 6.01(a) or in any 12-month period, Acquiror may only exercise its
right to impose a Blackout Period for any purpose under this Section 6.01(a) on
one (1) occasion for not more than 90 days and on one (1) additional occasion
for not more than 30 days (but, with respect to such additional occasion, only
to prohibit sales of Registrable Securities under a Shelf Registration
Statement). If so requested by the requesting Holder(s), Acquiror shall, if any
registration statement shall have been withdrawn, at such time as it is possible
or, if earlier, at the end of the 90-day period following such withdrawal, file
a new registration statement covering the Registrable Securities that were
covered by such withdrawn registration and maintain the effectiveness thereof
for such time as is required under this Agreement. The Holders may collectively
exercise their rights under this Section 6.01(a) on not more than two occasions
with respect to registration statements on Form S-1 and on not more than three
occasions with respect to registration statements on Form S-3; provided,
however, if the Holders do not exercise their rights under this Section 6.01(a)
with respect to the registration statements on Form S-1, the Holders may
exercise their rights under this Section 6.01(a) on not more than five (5)
occasions with respect to registration statements on Form S-3. At Acquiror's
option, Acquiror may elect to include in such registration on Form S-3,
securities to be issued by Acquiror and, if required in order to effect the
registration of such securities, cause the registration to be made pursuant to a
registration statement on Form S-1 or S-2, which shall count as one of the three
registration statements on Form S-3 to be filed pursuant to this Section
6.01(a). Holders of Registrable Securities will not be permitted to require
Acquiror to file a registration statement on Form S-1 or Form S-2 pursuant to
this Section 6.01(a) more frequently than once every 12 months. The registration
rights provided by this Section 6.01(a) shall expire upon the earlier to occur
of (i) such time when the Holders in the aggregate beneficially own Registrable
Securities representing less than 25% of the number of shares of Acquiror Common
Stock held by such Holders immediately following the Effective Time or

<PAGE>
                                      -45-

     (ii) five (5) years after the Exercise Date. If so requested by any Holder
in connection with a registration under this Section 6.01(a), Acquiror shall
take such steps as are required to register such Holder's Registrable Securities
for sale on a delayed or continuous basis under Rule 415, and also take such
steps as are required to keep any registration effective until the earlier to
occur of such time when (i) all of such Holder's Registrable Securities
registered thereunder are sold or (ii) 90 days after the effective date of the
registration statement; provided that such period shall be extended by an
additional 90-day period if, during the initial 90-day period, as a result of
materially adverse market conditions during such initial 90-day period, such
Holder has sold not more than the lesser of (x) 15% of the aggregate amount of
the Registrable Securities and (y) 50% of the Registrable Securities registered
by such Holder pursuant to the registration statement used during the initial
90-day period; provided, further, if any Blackout Period is imposed by the
Acquiror pursuant to this Section 6.01(a), such 180 day period or 90 day period,
as the case may be, relating to such registration statement shall be extended
for a period equal to such Blackout Period. Notwithstanding the foregoing, a
registration requested by a Holder of Registrable Securities pursuant to this
Section 6.01(a) shall not be deemed to have been effected (and, therefore, not
requested (and rights of a Holder shall be deemed not to have been exercised)
for purposes of this Section 6.01(a)), (i) unless it has become effective, (ii)
if after it has become effective such registration is interfered with by any
stop order, injunction or other order or requirement of the SEC or any
Governmental Entity other than a misrepresentation or an omission by such
Holder, and as a result thereof, the Registrable Securities requested to be
registered cannot be completely distributed in accordance with the plan of
distribution set forth in the related registration statement or (iii) if the
conditions to closing specified in the underwriting agreement entered into in
connection with such registration are not satisfied or waived other than solely
by reason of some act or omission by such Holder of Registrable Securities. In
the event that any registration pursuant to this Section 6.01(a) shall involve,
in whole or in part, an underwritten offering, the Holders will have the right
to select Acquiror's lead underwriter of such underwritten offering; provided,
however, that if Acquiror is required to select MSCP or an Affiliate thereof as
the lead underwriter for any underwritten offering by Acquiror pursuant to that
certain Registration Rights Agreement dated as of July 8, 1998, by and among
Acquiror, MSCP and certain other parties thereto (the "MSCP Agreement"), a copy
of which was provided to the Holders on the date hereof, the Holders shall
choose MSCP or such Affiliate thereof as the lead underwriter for any
underwritten offering pursuant to this Section 6.01(a) during the term of the
MSCP Agreement. The Holders of Registrable Securities shall not have the right
to exercise any registration rights under this Section 6.01(a) until after the
earlier to occur of (x) the completion of a sale of Acquiror Common Stock
pursuant to at least one (1) demand registration by the holders of Founder
Securities pursuant to Section 2.01 of the MSCP Agreement, or (y) two (2) years
after the Closing (the date when the Holders may exercise any registration
rights under this Section 6.01(a) being referred to herein as the "Exercise
Date") Notwithstanding anything else contained herein, any registration under
this Section 6.01 may not be used by the Holders for any transaction or
structure (whether or not including a trust or other intermediary) involving a
derivative, forward sale, short selling or similar transactions (except for
transactions (a) involving solely private sales in the over-the-counter market
and (b) which do not in any way involve the registration of any security other
than Acquiror Common Stock (such exception, the "Permitted Derivative
Transactions")) and may only be used by the Holders to effect direct transfers,
underwritten sales or the Permitted Derivative Transactions.

<PAGE>
                                      -46-

         (b)      If on any occasion at least 180 days after Closing, Acquiror
proposes to register any of its common stock, any other of its equity securities
or securities convertible into or exchangeable for its equity securities
(collectively, including common stock, "Other Securities") under the Securities
Act, whether or not for sale for its own account, in a manner that would permit
registration of Registrable Securities for sale for cash to the public under the
Securities Act, it shall prior to such time as all Holders in the aggregate
beneficially own less than 15% of the number of shares of Acquiror Common Stock
held by such Holders immediately following the Effective Time, give prompt
written notice to each Holder of Registrable Securities of its intention to do
so and of the rights of such Holder under this paragraph. Subject to the terms
and conditions hereof, such notice shall offer each such Holder the opportunity
to include in such registration statement such number of Registrable Securities
as such Holder may request. Upon the written request of any such Holder made
within 15 days after the receipt of Acquiror's notice (which request shall
specify the number of Registrable Securities intended to be disposed of and the
intended method of disposition thereof), Acquiror shall use its best efforts to
effect, in connection with the registration of the Other Securities, the
registration under the Securities Act of all Registrable Securities which
Acquiror has been so requested to register, to the extent required to permit the
disposition (in accordance with such intended methods thereof) of the
Registrable Securities so requested to be registered; provided, that:

                  (i) if, at any time after giving such written notice of its
         intention to register any Other Securities and prior to the effective
         date of the registration statement filed in connection with such
         registration, Acquiror shall determine for any reason not to register
         the Other Securities, Acquiror may, at its election, give written
         notice of such determination to such Holders and thereupon Acquiror
         shall be relieved of its obligation to register such Registrable
         Securities in connection with the registration of such Other
         Securities, without prejudice, however, to the rights of the Holders of
         Registrable Securities immediately to request that such registration be
         effected as a registration under Section 6.01(a) to the extent
         permitted thereunder;

                  (ii) if the registration referred to in the first sentence of
         this paragraph is to be an underwritten registration on behalf of
         Acquiror, and a nationally recognized investment banking firm selected
         by Acquiror advises Acquiror in writing that, in such firm's good faith
         view, the inclusion of all or a part of such Registrable Securities in
         such registration would be likely to have an adverse effect upon the
         price, timing or distribution of the offering and sale of the Other
         Securities then contemplated, Acquiror shall include in such
         registration: (A) first, all Other Securities Acquiror proposes to sell
         for its own account ("Acquiror Securities"), (B) second, up to the full
         number of Acquiror securities held by any Persons holding registration
         rights pursuant to MSCP Agreement that have requested to be included in
         such registration ("Founder Securities"), (C) third, up to the full
         number of Registerable Securities held by Holders of Registerable
         Securities that are requested to be included in such registration in
         excess of the number of Acquiror Securities and Founder Securities to
         be sold in such offering which, in the good faith view of such
         investment banking firm, can be so sold without so adversely affecting
         such offering (and (x) if such number is less than the full number of
         such Registrable Securities, such number shall be allocated pro rata
         among such Holders on the basis of the relative number of Registrable
         Securities then held by each such Holder (provided that any number in
         excess of a Holder's request may be reallocated among the requesting

<PAGE>
                                      -47-

         Holders in a like manner) and (y) in the event that such investment
         banking firm advises Acquiror in writing pursuant to this subclause
         (ii) that less than all of such Registrable Securities should be
         included in such offering, such Holders may withdraw their request for
         registration of their Registrable Securities under this Section 6.01(b)
         and request that 90 days subsequent to the effective date of the
         registration statement for the registration of such Other Securities
         such registration of Registrable Securities be effected as a
         registration under Section 6.01(a) to the extent permitted thereunder),
         and (D) fourth, up to the full number of the Other Securities (other
         than Acquiror Securities), if any, in excess of the number of Acquiror
         Securities, Founder Securities and Registrable Securities to be sold in
         such offering which, in the good faith view of such investment banking
         firm, can be so sold without so adversely affecting such offering (and,
         if such number is less than the full number of such Other Securities,
         such number shall be allocated pro rata among the holders of such Other
         Securities (other than Acquiror Securities) on the basis of the number
         of securities requested to be included therein by each such holder);

                  (iii) Acquiror shall not be required to effect any
         registration of Registrable Securities under this Section 6.01(b)
         incidental to the registration of any of its securities in connection
         with mergers, acquisitions, exchange offers, subscription offers,
         dividend reinvestment plans or stock option or other executive or
         employee benefit or compensation plans; and

                  (iv) no registration of Registrable Securities effected under
         this Section 6.01(b) shall relieve Acquiror of its obligation to effect
         a registration of Registrable Securities pursuant to Section 6.01(a).

         (c)      For the purposes of this Section 6.01, the term "Registrable
Securities" shall mean any shares of common stock of Acquiror acquired hereunder
and any securities issued directly or indirectly with respect to such common
stock by way of a split, dividend, or other division of securities, or in
connection with a combination of securities, recapitalization, merger,
consolidation, or other reorganization. As to any particular Registrable
Securities, such Registrable Securities shall cease to be Registrable Securities
when they (i) have been effectively registered under the Securities Act and
disposed of in accordance with the registration statement covering them or (ii)
repurchased by Acquiror or otherwise have ceased to be outstanding.

         (d)      Whenever under the preceding paragraphs of this Section 6.01
Acquiror is required hereunder to register any Registrable Securities, it agrees
that it shall as promptly as practicable also do the following:

                  (i) Prepare, file and use its reasonable best efforts to cause
         to become effective a registration statement under the Securities Act
         relating to the Registrable Securities to be offered in accordance with
         the intended method of disposition thereof;

                  (ii) Prepare and file with the SEC such amendments and
         supplements to such registration statement and the prospectus used in
         connection therewith as may be necessary to keep such registration
         statement effective and to comply with the provisions of the Securities
         Act with respect to the disposition of all Registrable Securities until
         such

<PAGE>
                                      -48-

         time as all of such Registrable Securities have been disposed of in
         accordance with the intended methods of disposition set forth in such
         registration statement; provided that the Acquiror will, at least five
         (5) business days prior to filing a registration statement or
         prospectus or any amendment or supplement thereto, furnish to each
         selling Holder copies of such registration statement or prospectus (or
         amendment or supplement) as proposed to be filed (including, upon the
         request of such Holder, documents to be incorporated by reference
         therein) which documents will be subject to the reasonable review and
         comments of such Holder (and its attorneys) during such 5-business-day
         period and the Acquiror will not file any registration statement, any
         prospectus or any amendment or supplement thereto (or any such
         documents incorporated by reference) containing any statements with
         respect to such Holder to which such Holder shall reasonably object in
         writing;

                  (iii) Furnish to the Holders of Registrable Securities and to
         any underwriter of such Registrable Securities such number of conformed
         copies of such registration statement and of each such amendment and
         supplement thereto (in each case including all exhibits), such number
         of copies of the prospectus included in such registration statement
         (including each preliminary prospectus and any summary prospectus), in
         conformity with the requirements of the Securities Act, such documents
         incorporated by reference in such registration statement or prospectus,
         and such other documents, as the selling Holders or such underwriter
         may reasonably request, and a copy of any and all transmittal letters
         or other correspondence to or received from, the SEC or any other
         governmental agency or self-regulatory body or other body having
         jurisdiction (including any domestic or foreign securities exchange)
         relating to such offering;

                  (iv) After the filing of the registration statement, promptly
         notify each selling Holder in writing of the effectiveness thereof and
         of any stop order issued or threatened by the SEC and take all
         reasonable actions required to prevent the entry of such stop order or
         to promptly remove it if entered and promptly notify such selling
         Holder of such lifting or withdrawal of such order;

                  (v) Use its reasonable best efforts to cause all Registrable
         Securities covered by such registration statement to be registered with
         or approved by such other governmental agencies or authorities as may
         be necessary to enable the selling Holders to consummate the
         disposition of such Registrable Securities;

                  (vi)     Enter into any reasonable underwriting agreement
         required by the proposed underwriter for the selling Holders, if any;

                  (vii) Use its reasonable best efforts to register or qualify
         all Registrable Securities covered by said registration statement under
         the securities or "blue-sky" laws of such jurisdictions as any selling
         Holder or any underwriter may request and use its reasonable best
         efforts to obtain all appropriate registrations, permits and consents
         in connection therewith, and do any and all other acts and things which
         may be necessary or advisable to enable the Holders of Registrable
         Securities or any such underwriter to consummate the disposition in
         such jurisdictions of its Registrable Securities covered by such
         registration statement; provided that Acquiror shall not be required to
         register or

<PAGE>
                                      -49-

         qualify the securities in any jurisdictions which require it to qualify
         to do business or subject itself to taxation or general service of
         process therein;

                  (viii) Immediately notify each selling Holder in writing, (i)
         at any time when a prospectus relating to his, her or its Registrable
         Securities is required to be delivered under the Securities Act, of the
         happening of any event as a result of which such prospectus contains an
         untrue statement of a material fact or omits to state any material fact
         required to be stated therein or necessary to make the statements
         therein not misleading, and (ii) of any request by the SEC or any other
         regulatory body having jurisdiction for any amendment or supplement to
         any registration statement or other document relating to such offering,
         and in either such case, at the request of any such selling Holder,
         prepare and furnish a supplement or amendment to such prospectus so
         that, as thereafter delivered to the purchasers of such Registrable
         Securities, such prospectus will not contain any untrue statement of a
         material fact or omit to state any material fact required to be stated
         therein or necessary to make the statements therein not misleading;

                  (ix) Use its reasonable best efforts to cause all such
         Registrable Securities to be listed on or included in each securities
         exchange or quotation system on which similar securities issued by
         Acquiror are then listed;

                  (x) Otherwise use its reasonable best efforts to comply with
         all applicable rules and regulations of the SEC and make generally
         available to its security holders, in each case as soon as practicable,
         but not later than 30 days after the close of the period covered
         thereby an earnings statement of Acquiror which will satisfy the
         provisions of Section 11(a) of the Securities Act;

                  (xi) (A) Use its reasonable best efforts to furnish to each
         selling Holder and to any underwriter of such Registrable Securities an
         opinion of counsel for the Acquiror addressed to each selling Holder
         and dated the date of the closing under the underwriting agreement (if
         any) (or if such offering is not underwritten, dated the effective date
         of the registration statement), and (B) use its reasonable best efforts
         to furnish to each selling Holder a "cold comfort" letter addressed to
         each selling Holder and signed by the independent public accountants
         who have audited the financial statements of the Acquiror included in
         such registration statement, in each such case covering substantially
         the same matters with respect to such registration statement (and the
         prospectus included therein) as are customarily covered in opinions of
         issuer's counsel and in accountants' letters delivered to underwriters
         in connection with the consummation of underwritten public offerings of
         securities and such other matters as the selling Holders may reasonably
         request and, in the case of such accountants' letter, with respect to
         events subsequent to the date of such financial statements;

                  (xii) Send appropriate officers of the Acquiror to attend any
         "road shows" and rating agency, analyst and investor presentations
         scheduled in connection with any such registration and use its
         reasonable best efforts to cooperate as reasonably requested by the
         Holders in the marketing of the Registrable Securities, and all
         reasonable out-of-pocket

<PAGE>
                                      -50-

         costs and expenses incurred by the Acquiror or such officers in
         connection with such attendance or co-operation shall be paid by the
         Acquiror; and

                  (xiii) Furnish for delivery in connection with the closing of
         any offering of Registrable Securities pursuant to a registration
         effected pursuant to Section 6.01(a) or (b) unlegended certificates
         representing ownership of the Registrable Securities being sold in such
         denominations as shall be requested by the selling Holders or the
         underwriters.

                  (xiv) Choose the auditors, Acquiror legal counsel and
         financial printer to be engaged by Acquiror in any such registration.

         (e)      Incident to any registration statement referred to in this
Section 6.01, and subject to applicable law, Acquiror will indemnify and hold
harmless each underwriter, each Holder of Registrable Securities (including its
respective partners, directors, officers, employees and agents) so registered,
and each person who controls any of them within the meaning of Section 15 of the
Securities Act or Section 20 of the Exchange Act, from and against any and all
losses, claims, damages, expenses and liabilities, joint or several (including
any investigation, legal and other expenses incurred in connection with, and any
amount paid in settlement of, any action, suit or proceeding or any claim
asserted), to which they, or any of them, may become subject under the
Securities Act, the Exchange Act or other federal or state statutory law or
regulation, at common law or otherwise, insofar as such losses, claims, damages
or liabilities arise out of or are based on (i) any untrue statement or alleged
untrue statement of a material fact contained in such registration statement
(including any related preliminary or definitive prospectus, or any amendment or
supplement to such registration statement or prospectus), (ii) any omission or
alleged omission to state in such document a material fact required to be stated
in it or necessary to make the statements in it not misleading, or (iii) any
violation by Acquiror of the Securities Act, any state securities or "blue sky"
laws or any rule or regulation thereunder in connection with such registration,
provided that Acquiror will not be liable to the extent that such loss, claim,
damage, expense or liability (x) arises from and is based on an untrue statement
or omission or alleged untrue statement or omission made in reliance on and in
conformity with information furnished in writing to Acquiror by such
underwriter, Holder or controlling person expressly for use in such registration
statement or (y) arises from the failure of any Holder or underwriter to comply
with such prospectus delivery requirements as are applicable to it. With respect
to such untrue statement or omission or alleged untrue statement or omission in
the information furnished in writing to Acquiror by such Holder expressly for
use in such registration statement or such failure to comply with such
prospectus delivery requirements, such Holder will indemnify and hold harmless
each underwriter, Acquiror (including its directors, officers, employees and
agents), each other Holder of Registrable Securities (including its respective
partners directors, officers, employees and agents) so registered, and each
person who controls any of them within the meaning of Section 15 of the
Securities Act or Section 20 of the Exchange Act, from and against any and all
losses, claims, damages, expenses and liabilities, joint or several, to which
they, or any of them, may become subject under the Securities Act, the Exchange
Act or other federal or state statutory law or regulation, at common law or
otherwise to the same extent provided in the immediately preceding sentence. In
no event, however, shall the liability of a Holder for indemnification under
this paragraph exceed the net proceeds received by such Holder from its sale of
Registrable Securities under such registration statement. Each

<PAGE>
                                      -51-

Holder's obligation to indemnify pursuant to this Section is several in the
proportion that the net proceeds of the offering received by such holder bear to
the total proceeds of the offerings received by all Holders and not joint.

         (f)      Each party indemnified under Section 6.01(e) above shall,
promptly after receipt of notice of a claim or action against such indemnified
party in respect of which indemnity may be sought hereunder, notify the
indemnifying party in writing of the claim or action and the indemnifying party
shall assume the defense thereof, including the employment of counsel reasonably
satisfactory to such indemnified party, and shall assume the payment of all fees
and expenses; provided that the failure of any indemnified party so to notify
the indemnifying party shall not relieve the indemnifying party of its
obligations hereunder except to the extent that the indemnifying party is
materially prejudiced by such failure to notify. In any such action, any
indemnified party shall have the right to retain its own counsel, but the fees
and expenses of such counsel shall be at the sole expense of such indemnified
party unless (i) the indemnifying party and the indemnified party shall have
mutually agreed to the retention of such counsel or (ii) in the reasonable
judgment of such indemnified party representation of both parties by the same
counsel would be inappropriate due to actual or potential differing interests
between them, in which case the fees and expenses of such counsel shall be at
the sole expense of the indemnifying party. It is understood that the
indemnifying party shall not, in connection with any claim or action or related
proceeding in the same jurisdiction, be liable for the reasonable fees and
expenses of more than one separate firm of attorneys (in addition to any local
counsel) at any time for all such indemnified parties, and that all such fees
and expenses shall be reimbursed as they are incurred. In the case of any such
separate firm for the Holders as indemnified parties, such firm shall be
designated in writing by the indemnified party that had the largest number of
Registrable Securities included in such registration. The indemnifying party
shall not be liable for any settlement of any claim or action effected without
its written consent, which consent shall not be unreasonably withheld or
delayed, but if settled with such consent, or if there be a final judgment for
the plaintiff, the indemnifying party shall indemnify and hold harmless such
indemnified parties from and against any loss or liability (to the extent stated
above) by reason of such settlement or judgment. No indemnifying party shall,
without the prior written consent of the indemnified party, effect any
settlement of any pending or threatened claim or action in respect of which any
indemnified party is or could have been a party and indemnity could have been
sought hereunder by such indemnified party, unless such settlement includes an
unconditional release of such indemnified party from all liability arising out
of such proceeding.

         (g)      If the indemnification provided for in this Section 6.01 shall
for any reason be unavailable (other than in accordance with its terms) to an
indemnified party in respect of any loss, liability, cost, claim or damage
referred to therein, then each indemnifying party shall, in lieu of indemnifying
such indemnified party, contribute to the amount paid or payable by such
indemnified party as a result of such loss, liability, cost, claim or damage (A)
as between the Acquiror and the underwriters, (i) in such proportion as is
appropriate to reflect the relative benefits received by the Acquiror on the one
hand and the underwriters on the other hand from the offering of the Registrable
Securities or (ii) if the allocation provided by clause (i) above is not
permitted by applicable law, in such proportion as is appropriate to reflect not
only the relative benefits referred to in clause (i) above but also the relative
fault of the indemnifying party or parties on the one hand and of the
indemnified party or parties on the other hand in

<PAGE>
                                      -52-

connection with the statements or omissions that resulted in such losses,
claims, damages or liabilities, as well as any other relevant equitable
considerations, and (B) as between (x) the Acquiror and the selling Holders, or
(y) the selling Holders and the underwriters, in such proportion as is
appropriate to reflect the relative fault of the indemnifying party or parties
on the one hand and of the indemnified party or parties on the other hand in
connection with the statements or omissions that resulted in such losses,
claims, damages or liabilities, as well as any other relevant equitable
considerations. The relative benefits received by the Acquiror on the one hand
and the underwriters on the other hand in connection with the offering of the
Registrable Securities shall be deemed to be in the same respective proportions
as the net proceeds from the offering of the Registrable Securities (before
deducting expenses) (as if, for purposes of this Section 6.01(g), the Acquiror
had received the proceeds of any secondary offering) and the total underwriting
discounts and commissions received by the underwriters, in each case as set
forth in the table on the cover of a prospectus, bear to the aggregate public
offering price of the Registrable Securities. The relative fault of the
Acquiror, the selling Holders and the underwriters shall be determined by
reference to, among other things, whether the untrue or alleged untrue statement
of a material fact or the omission or alleged omission to state a material fact
relates to information supplied by the Acquiror, by a selling Holder or by the
underwriters and the parties' relative intent, knowledge, access to information
and opportunity to correct or prevent such statement or omission. The amount
paid or payable by an indemnified party as a result of the loss, cost, claim,
damage or liability, or action in respect thereof, referred to above in this
Section 6.01(g) shall be deemed to include, for purposes of this Section
6.01(g), any legal or other costs, fees and expenses reasonably incurred by such
indemnified party in connection with investigating or defending any such action
or claim. The Acquiror and the selling Holders agree that it would not be just
and equitable if contribution pursuant to this Section 6.01 were determined by
pro rata allocation (even if the underwriters were treated as one entity for
such purpose) or by any other method of allocation which does not take account
of the equitable considerations referred to in this Section 6.01(g).
Notwithstanding any other provision of this Section 6.01, no selling Holder
shall be required to contribute any amount in excess of the amount by which the
net proceeds of the offering received by such selling Holder exceed the amount
of any damages which such selling Holder has otherwise been required to pay by
reason of such untrue or alleged untrue statement or omission or alleged
omission. Each selling Holder's obligations to contribute pursuant to this
Section are several in the proportion that the net proceeds of the offering
received by such selling Holder bears to the total net proceeds of the offering
received by all the selling Holders and not joint. No person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation.

         (h)      Indemnification and contribution similar to that specified in
the preceding subsections of this Section 6.01 (with appropriate modifications)
shall be given by the Acquiror, the selling Holders and the underwriters with
respect to any required registration or other qualification of securities under
any state law or regulation or governmental authority.

         (i)      With a view to making available the benefits of certain rules
and regulations of the SEC which may permit the sale of the Registrable
Securities to the public without registration, Acquiror agrees to: (i) make and
keep public information available as those terms are understood and defined in
Rule 144 under the Securities Act (and any successor rule to Rule 144); (ii)
file with the SEC in a timely manner all reports and other documents required of

<PAGE>
                                      -53-

Acquiror under the Securities Act and the Exchange Act; (iii) furnish to each
Holder as promptly as possible upon its request a written statement by Acquiror
confirming its compliance with the reporting requirements of Rule 144 (at any
time from and after May 16, 2000), and of the Securities Act and the Exchange
Act, a copy of the most recent annual or quarterly report of Acquiror, and any
other reports and documents so filed as a holder may reasonably request in
availing itself of any rule or regulation of the SEC allowing a holder to sell
any such securities without registration; and (iv) promptly upon request of any
Holder, use its reasonable best efforts to comply, in connection with any
resales by the Investors, pursuant to Rule 144A, with the informational
requirements of Rule 144A(d)(4) (and any successor rule to Rule 144A(d)(4)).

         (j)      If requested by the underwriters for any underwritten offering
of Registrable Securities pursuant to a registration requested under this
Section 6.01, the Acquiror shall enter into an underwriting agreement with such
underwriters for such offering, which agreement will contain such
representations and warranties and covenants by the Acquiror and such other
terms and provisions as are customarily contained in underwriting agreements
with respect to secondary distributions, including, without limitation,
indemnification and contribution provisions substantially to the effect and to
the extent provided in Section 6.01, and agreements as to the provision of
opinions of counsel and accountants' letters to the effect and to the extent
provided in Section 6.01(d)(xi). The selling Holders on whose behalf the
Registrable Securities are to be distributed by such underwriters shall be
parties to any such underwriting agreement and the representations and
warranties by, and the other agreements on the part of, the Acquiror to and for
the benefit of such underwriters, shall also be made to and for the benefit of
such selling Holders. Such underwriting agreement shall also contain such
representations and warranties by such selling Holders and such other terms and
provisions as are customarily contained in underwriting agreements with respect
to secondary distributions on the part of selling shareholders, including,
without limitation, indemnification and contribution provisions substantially to
the effect and to the extent provided in Section 6.01.

         (k)      In connection with the preparation and filing of each
registration statement registering Registrable Securities under the Securities
Act pursuant to this Section 6.01, the Acquiror shall give the Holders of such
Registrable Securities and the underwriters, if any, and their respective
counsel and accountants, such reasonable and customary access to its books,
records and properties and such opportunities to discuss the business and
affairs of the Acquiror with its officers and the independent public accountants
who have certified the financial statements of the Acquiror as shall be
necessary, in the opinion of such Holders and such underwriters or their
respective counsel, to conduct a reasonable investigation within the meaning of
the Securities Act; provided, that such Holders and the underwriters and their
respective counsel and accountants shall use their reasonable best efforts to
coordinate any such investigation of the books, records and properties of the
Acquiror and any such discussions with the Acquiror's officers and accountants
so that all such investigations occur at the same time and all such discussions
occur at the same time.

         (l)      The rights described in this Section 6.01 shall be
transferable only to Affiliates of the Company Stockholder or members of his
immediate family, spouses, lineal descendants and members of the Company
Stockholder's immediate family or trusts for their benefit or upon the Company
Stockholder's death, his executor, administrator, testamentary trustee,
legatees, heirs or beneficiaries (collectively, the "Permitted Transferees" and
each, a "Permitted Transferee").

<PAGE>
                                      -54-

Only the Company Stockholder and his Permitted Transferees shall be deemed to be
to be a "Holder" for purposes of this Section 6.01.

         (m)      Notwithstanding anything to the contrary, for purposes of

hold harmless Acquiror, the Surviving Corporation and their respective officers
and directors, and each Person, if any, who controls or may control Acquiror or
the Surviving Corporation within the meaning of the Securities Act (all such
persons hereinafter are referred to individually as an "Indemnified Person" and
collectively as "Indemnified Persons," but in no event shall any stockholder of
the Company be such an Indemnified Person), from and against any and all losses,
costs, damages, liabilities and expenses, including reasonable attorneys' fees
and expenses ("Damages") actually suffered by them and arising out of the breach
of the representations, warranties, covenants and agreements given or made by
the Company in this Merger Agreement, in the Articles of Merger or in the
Exhibits or Schedules hereto or in any certificate delivered by or on behalf of
the Company pursuant hereto; provided however, that the Company Stockholder
shall have no

<PAGE>
                                      -59-

liability under this Section 6.10(a) to the extent claims for Damages hereunder
do not exceed an aggregate of $500,000 and that if such Damages exceed an
aggregate of $500,000 then the indemnification provided for hereunder shall
apply only to Damages to the extent exceeding $500,000. Notwithstanding anything
to the contrary contained in this Merger Agreement, the maximum amount of
indemnifiable Damages which may be recovered from the Company Stockholder
arising out of or resulting from the causes enumerated in this Section 6.10(a)
and Section 6.10(b) shall be $125 million; provided, however, that such
limitation on the indemnification obligations of the Company Stockholder shall
not apply to any claim or claims for indemnification to the extent such claim or
claims are based on common law fraud. It shall be a condition of the right of
each Indemnified Person to indemnification pursuant to this Section 6.10(a) that
such Indemnified Person shall deliver to the Company Stockholder a written claim
for such indemnification, setting forth in reasonable detail the basis therefor
and setting forth the amount of damages sought, on or prior to the date that the
particular representation, warranty, covenant or agreement for the breach of
which the indemnification is being sought, expires under the terms of this
Merger Agreement.

         (b)      In addition to the indemnification provided by the Company
Stockholder as set forth in Section 6.10(a), the Company Stockholder shall
indemnify and hold harmless the Indemnified Persons for Damages actually
suffered by them and arising out of the breach of the representations,
warranties, covenants and agreements given or made by the Company Stockholder in
this Merger Agreement or in its Exhibits or Schedules thereto or in any
certificate delivered by or on behalf of the Company Stockholder pursuant
hereto.

         (c)      Any payment to be made to an Indemnified Person by the Company
Stockholder under this Section 6.10 may be made in cash or, in whole or in part,
in Acquiror Common Stock having a value per share equal to the Price Per Share.
The Company Stockholder and Acquiror agree that any payment required to be made
by the Company Stockholder shall first be made pursuant to the terms of and from
the escrow established under the Escrow Agreement attached as Exhibit C.

         (d)      After the Effective Time, indemnification pursuant to this
Section 6.10 shall be the sole and exclusive remedy of Acquiror and the
Surviving Corporation under or in connection with this Merger Agreement or any
of the transactions contemplated herein, except that Acquiror and the Surviving
Corporation shall be entitled to obtain specific performance or injunctive
relief in connection with the enforcement of any of the covenants set forth
herein which by their terms continue after the Effective Time.

         SECTION 6.11.  Procedures; Conditions of Indemnification.

         With respect to any indemnification provided pursuant to this Merger
Agreement, the Indemnified Person agrees to give prompt written notice to the
Company Stockholder of any claim or other assertion of liability by third
parties (hereinafter called collectively "Claims"), it being understood that the
failure to give such notice shall not affect the Indemnified Person's right to
indemnification and the indemnifying party's obligation to indemnify as set
forth in this Merger Agreement, unless the Company Stockholder's rights with
respect to such Claim are thereby materially prejudiced.

<PAGE>
                                      -60-

         The obligations and liabilities of the parties hereto with respect to
any indemnification by the Company Stockholder pursuant to this Merger Agreement
resulting from any Claim shall be subject to the following terms and conditions:

         (a)      The Company Stockholder shall have the right to undertake, by
counsel or other representatives of his own choosing, the defense of such Claim.

         (b)      In the event that the Company Stockholder shall elect not to
undertake such defense, or within a reasonable time after notice of any such
Claim from the Indemnified Person shall fail to defend, the Indemnified Person
(upon further written notice to the Company Stockholder) shall have the right to
undertake the defense, compromise or settlement of such Claim, by counsel or
other representatives of its own choosing, on behalf of and for the account and
risk of the Company Stockholder (subject to the right of the Company
Stockholder, to assume defense of such Claim at any time prior to settlement,
compromise or final determination thereof); provided however, that no settlement
or compromise of such Claim shall be made without the written consent of the
Company Stockholder which consent shall not be unreasonably withheld.

         (c)      Anything in this Section 6.11 to the contrary notwithstanding,
(i) if the Indemnified Person notifies the Company Stockholder that the
Indemnified Person has concluded that a Claim may materially and adversely
affect the Indemnified Person other than as a result of money damages or other
money payments, the Indemnified Person shall have the right, at its own cost and
expense, to participate in the defense, compromise or settlement of the Claim;
provided, however, that the Indemnified Person shall not have the right to
participate with respect to a Claim relating to Taxes if the Claim relates to
Taxes of the Company or any Subsidiary for taxable years or taxable periods
ending on or prior to the Closing Date, (ii) the Company Stockholder shall not,
without the Indemnified Person's written consent, settle or compromise any Claim
or consent to entry of any judgment that does not include as an unconditional
term thereof the giving by the claimant or the plaintiff to the Indemnified
Person of a release from all liability in respect of such Claim, and (iii) in
the event that the Company Stockholder undertakes defense of any Claim, the
Indemnified Person, by counsel or other representative of its own choosing and
at its sole cost and expense, shall have the right to consult with the Company
Stockholder and his counsel or other representatives concerning such Claim and
the Company Stockholder and the Indemnified Person and their respective counsel
or other representatives shall cooperate with respect to such Claim.

         (d)      Notwithstanding any other provision of this Section 6.11 and
with the exception of any Claim relating to Taxes as provided above, the
Indemnified Person may at any time assume full control over the responsibility
for any Claim (other than a Claim against the Company Stockholder, by written
notice to the Company Stockholder releasing the Company Stockholder from any
further indemnity obligation pursuant to this Merger Agreement with respect to
said Claim.

         (e)      Each of (A) Company Stockholder and (B) Acquiror, for itself
and on behalf of its Affiliates, agrees that, with respect to each
indemnification obligation contained in this Merger Agreement, (i) each such
obligation shall be calculated after reduction for any actual Tax benefit to the
Indemnified Person (including the Company, the Subsidiaries or any Affiliate of
the

<PAGE>
                                      -61-

Indemnified Person) that arises in connection with the payment of the Damage or
otherwise with respect to the underlying claims giving rise to such Damage and
which is utilized by the Indemnified Person in the taxable year in which the
Claim is paid; (ii) all Damages shall be net of (x) any third-party insurance
proceeds actually received by the Indemnified Person from its own or its
Affiliates' insurance policies in connection with the facts giving rise to the
right of indemnification and (y) all premiums paid by Acquiror or its Affiliates
under such policies; and (iii) all Damages paid pursuant to Section 6.10 shall
be calculated so as to take into account all increases in actual Tax liability
payable by the Indemnified Person with respect to the taxable year in which the
Damages are paid as a result of the receipt of such payment; provided, however,
that each of (x) the Company Stockholder and (y) the Acquiror, for itself and on
behalf of its Affiliates, agrees to report each payment of Damages hereunder as
an adjustment to the Merger Consideration for federal income tax purposes unless
the Indemnified Person determines in good faith that such reporting position
cannot be supported on a more likely than not basis (it being understood that if
any such reporting position is later disallowed in any administrative or court
proceeding, Company Stockholder shall indemnify the Indemnified Person for the
effects of such disallowance). If a payment is made by the Company Stockholder
in accordance with Section 6.10 and Section 6.11, and if in a subsequent taxable
year a Tax benefit described in the previous sentence is utilized by Acquiror,
then Acquiror promptly shall pay to the Company Stockholder, at the time of such
utilization, the amount of such Tax benefit to the extent that such amount would
have resulted in a reduction in the indemnification obligations of the Company
Stockholder under Section 6.10 and Section 6.11 if the Tax benefit had been
utilized by Acquiror in the taxable year that the Company Stockholder made such
indemnification payment.

         (f)      Acquiror and the Company Stockholder acknowledge and agree
that anything herein to the contrary notwithstanding, no breach of any
representation, warranty, covenant or agreement contained herein shall give rise
to any right on the part of Acquiror or the Company Stockholder, after the
consummation of the Merger contemplated by this Agreement, to rescind this
Agreement or any of the transactions contemplated hereby.

         SECTION 6.12.  Tax Returns.

         To the extent permitted under applicable Tax Laws, the Merger shall be
reported as a "reorganization" within the meaning of Section 368(a) and Section
368(a)(2)(D) of the Code in all federal, state and local Tax Returns filed after
the Effective Time. To the extent permitted under applicable Tax Laws, no party
to this Merger Agreement shall take any position inconsistent with the foregoing
on any Tax Return, in any audits or proceeding or otherwise. Notwithstanding any
other provision of this Merger Agreement, the obligations set forth in this
Section 6.12(a) shall survive the Effective Time without limitation as to time
or in any other respect.

         SECTION 6.13.  Reorganization.

         During the period from the date of this Merger Agreement through the
Effective Time, unless Acquiror and the Company shall otherwise agree in
writing, Acquiror and the Company shall not, and shall cause their respective
subsidiaries not to, and the Company Stockholder shall

<PAGE>
                                      -62-

not, knowingly take or fail to take any action which action or failure would
jeopardize the qualification of the Merger as a reorganization within the
meaning of Section 368(a) of the Code.

         SECTION 6.14.  Acquiror's Financing.

         Acquiror shall use its reasonable best efforts to cause the Buyer
Financing to be obtained substantially on the terms set forth in the Buyer
Financing Letters or to obtain alternative financing on terms not materially
less favorable to Acquiror than the terms of the Buyer Financing Letters. The
Company agrees to provide, and will cause the Company, the Subsidiaries and its
and their respective officers, managers, employees and advisors to provide,
reasonable cooperation in connection with the arrangement of the Buyer
Financing; provided that the terms and conditions of such financing may not
require, prior to the Effective Time, the payment of any commitment or similar
fees by the Company, or the incurrence of any liabilities by the Company.

         SECTION 6.15.  Obligations of Acquiror Sub.

         Acquiror shall take all action necessary to cause Acquiror Sub to
perform its obligations under this Merger Agreement and to consummate the Merger
on the terms and conditions set forth in this Merger Agreement and hereby
unconditionally guarantees to the Company that Acquiror Sub will perform all of
its obligations under this Merger Agreement.

         SECTION 6.16.  Loan Agreement.

         Concurrently with the execution of this Merger Agreement, US Xchange
Finance shall execute a Promissory Note in the form attached hereto as Exhibit A
(the "Promissory Note"), pursuant to which the Acquiror shall make available to
US Xchange Finance a loan (the "Credit Facility") on the terms and subject to
the conditions set forth therein. Acquiror's obligation to execute the
Promissory Note is subject to and conditioned upon Acquiror's receipt of (i) a
security agreement executed by US Xchange Finance and its Subsidiaries, pursuant
to which such Persons will grant to Acquiror a security interest in Assets to
secure US Xchange Finance's obligations under the Credit Facility, in
substantially the form of Exhibit A to the Promissory Note; and (ii) a personal
guarantee of Ronald H. VanderPol, in substantially the form attached as Exhibit
B to the Promissory Note.

         SECTION 6.17.  Transfer of Fiber Business; IRU and Maintenance
Agreement.

         (a)      Prior to the Closing, the Company will transfer all of its
fiber business (the "Fiber Business") to a company wholly-owned by the Company
Stockholder ("Barter Fiber") pursuant to an asset transfer agreement in form and
substance reasonably satisfactory to Acquiror, provided, however, that such
agreement shall provide: (i) that with respect to any employee engaged in the
conduct of both the Fiber Business and any other business of the Company and the
Subsidiaries, the Acquiror shall have the right to retain such employee upon the
Closing and (ii) that with respect to any asset which is used in both the Fiber
Business and any other business of the Company and the Subsidiaries, the
Acquiror shall have the right to retain ownership of such asset upon the Closing
but shall make such asset available to Barter Fiber at cost plus allocable
overhead to the extent that such asset is used in the Fiber Business; provided,
however, that with respect to any asset which is at least 66% used in the Fiber
Business, such asset will be


<PAGE>

assigned to Barter Fiber and Barter Fiber shall make such asset available to
Acquiror at cost plus allocable overhead to the extent such asset is used in any
other business of the Company and the Subsidiaries, and (iii) that the Acquiror
shall provide access to Barter Fiber to the central offices where fiber is

         (b)      Acquiror Sub shall execute and deliver at Closing, and the
Company Stockholder agrees to cause Barter Fiber to execute and deliver at
Closing, the IRU and Maintenance Agreement in substantially the form attached
hereto as Exhibit D (the "IRU and Maintenance Agreement").

         SECTION 6.18.  Noncompetition Covenants.

         For a period of three (3) years commencing on the Closing Date, the
Company Stockholder will not:

         (i)      Directly or indirectly, engage in, own, control, or make a
significant non-controlling investment in, any business that competes directly
with the integrated communications provider business of Acquiror and/or the
Surviving Corporation (including any of the Subsidiaries) within the "Restricted
Area", provided that nothing in this Section 6.18 shall prohibit the Company
Stockholder or any of his Affiliates from (A) selling Dark Fiber or rights to
use Dark Fiber to any Person, (B) selling fiber, other than Dark Fiber, or
rights to use such fiber to wholesale carriers (which term, "wholesale
carriers," shall not include retail customers or other end users of such fiber),
or (C) conducting the directory business conducted by US Xchange Directory LLC.
For purposes of this Section 6.18, the term "Restricted Area" will mean the

Connecticut, New York, New Jersey, Pennsylvania, Michigan, Ohio, Wisconsin,
Indiana, Illinois, Virginia and Maryland and the District of Columbia;

         (ii)     Accept employment with any person or entity that competes
directly with the business of Acquiror and/or the Surviving Corporation
(including any of the Subsidiaries) within the Restricted Area as of the date
hereof;

         (iii)    Directly or indirectly solicit or employ any person who at
such time provides services for or is otherwise employed by Acquiror and/or the
Surviving Corporation (including any of the Subsidiaries), or encourage or
induce any employee of Acquiror and/or the Surviving Corporation (including any
of the Subsidiaries) to leave such employment, other than the Fiber Business
Employees set forth on Section 6.18 of the Company Disclosure Schedule; or

         (iv)     Directly or indirectly, divert or attempt to divert from the
Acquiror and/or the Surviving Corporation (including any of the Subsidiaries),
the business conducted in the Restricted Area of any customer, supplier or
client of Acquiror and/or the Surviving Corporation (including any of the
Subsidiaries).

         SECTION 6.19.  Representation on Acquiror's Board of Directors.

<PAGE>
                                      -64-

         Acquiror agrees to cause its Transaction Agreement, dated as of July 8,
1998, as amended, among Acquiror and certain of its institutional shareholders
and management shareholders, to be amended (the "Transaction Agreement
Amendment") to provide that the parties to such Transaction Agreement Amendment
will vote their shares of Acquiror which are subject to the terms thereof in
favor of the election of Richard Postma (or other designee of the Company
Stockholder approved by the Board of Directors, which approval shall not be
unreasonably withheld) to the Board of Directors of Acquiror so long as the
Company Stockholder owns at least 4,500,000 shares of Acquiror Common Stock.

         SECTION 6.20.  Restriction on Transfer of Acquiror Stock.

         The Company Stockholder shall not, during the period commencing on the
Closing Date and ending 180 days after the Closing Date, offer, sell, contract
to sell, grant any option, right or warrant to purchase, or otherwise gift,
assign, convey, transfer or dispose of, directly or indirectly, any shares of
Acquiror Stock; provided that the foregoing shall not apply to any transfer or
disposition of Acquiror Stock to a Permitted Holder (as hereinafter defined)
who, as a condition to any proposed transfer or disposition, shall agree in
writing with Acquiror to be bound by all of the provisions of this Section 6.20
to the same extent as if such transferee were a Company Stockholder. A
"Permitted Holder" shall mean: (i) any Permitted Transferee or any charitable
organization designated by any Permitted Transferee; (ii) any organization
described in Section 501(c)(3) of the Code; (iii) Barter Fiber; or (iv) any of
the Persons listed on Section 6.20 of the Company Disclosure Schedule. The stock
certificates issued by Acquiror pursuant to this Agreement shall be stamped or
imprinted with a legend in substantially the following form (in addition to any
legend required under applicable Federal or state securities laws): "Until
[insert date 180 days after the Closing Date], the securities represented by
this certificate may not be transferred, sold or assigned without obtaining the
prior written consent of the Corporation."

         SECTION 6.21.  Trademark License.

         The Acquiror Sub shall grant to US Xchange Directory LLC the right to
use the name "US Xchange" either alone or in connection with other words, for
its directory business, pursuant to the Trademark License Agreement in
substantially the form attached hereto as Exhibit E.

         SECTION 6.22.  Employee Benefits.

         (a)      For a period of at least two years following the Effective
Time, Acquiror shall provide or shall cause the Surviving Corporation and each
Subsidiary to provide benefits to any employee of the Surviving Corporation and
each Subsidiary which are not less favorable in the aggregate than the benefits
provided to similarly situated employees of the Acquiror and Acquiror
Subsidiaries or the benefits provided to similarly situated employees of the
Company of the Company's Subsidiaries immediately prior to the Effective Time.
From and after the Effective Time, solely for purposes of determining an
employee's vesting and eligibility rights under an employee benefit plan and not
for purposes of benefit accruals, Acquiror shall grant all employees of the
Surviving Corporation and any Subsidiaries credit for all service (to the same
extent as service with Acquiror or any Acquiror Subsidiary is taken into account
with respect to similarly situated employees of Acquiror and Acquiror
Subsidiaries) with the Company and any

<PAGE>
                                      -65-

Subsidiary and their respective predecessors prior to the Effective Time (but
only to the extent that the Company and its Subsidiaries granted credit for such
service) as if such service with the Company or any Subsidiary was service with
Acquiror or any Acquiror Subsidiary. Following the Effective Time, all employees
of the Surviving Corporation and any Subsidiaries shall be eligible to
participate in the Acquiror Stock Option Plan, and, in the discretion of the
Acquiror's Board of Directors, to receive grants of stock options under the
Acquiror Stock Option Plan. With respect to any new medical or dental benefit
plan established as of the Effective Time (if any), Acquiror shall waive any
pre-existing condition exclusions and actively at work requirements (provided,
however, that no such waiver shall apply to a pre-existing condition of any
employee of the Surviving Corporation or any Subsidiary who was, as of the
Effective Time, excluded from participation in a Plan by virtue of such
pre-existing condition or actively at work requirement) and provide that any
covered expenses incurred on or before the Effective Time by an employee or an
employee's covered dependent shall be taken into account for purposes of
satisfying applicable deductible, coinsurance and maximum out-of-pocket
provisions of any new medical or dental benefit plan established as of the
Effective Time (if any).

         (b)      The Company shall amend the Plans and take such necessary
actions prior to the Closing Date, consistent with applicable Laws, so that only
the Company's and the Subsidiaries' eligible current and former employees, and
their eligible spouses, former spouses, dependents or beneficiaries, shall
participate in the Plans as of the Effective Time. Such actions shall include,
but not be limited to, spinning off the assets and liabilities of that portion
of the Company's 401(k) Savings and Retirement Plan and its Flexible Benefit
Plan that are attributable to current or former employees of entities other than
the Company or the Subsidiaries to new plans established by the Company
Stockholder or an entity controlled by the Company Stockholder. Such spin-off
shall comply with all applicable Laws, including but not limited to Section
414(l) of the Code.

         SECTION 6.23.  Directors' and Officers' Indemnification.

         (a)      Acquiror and Acquiror Sub agree that all rights to
indemnification, including provisions relating to advances of expenses incurred
in defense of any claim, action, suit, proceeding or investigation (a "D&O
Claim") existing in favor of the D&O Indemnified Parties as provided in the
Company's Certificate of Incorporation or By-laws, as in effect as of April 11,
2000, with respect to matters occurring through the Effective Time, shall
survive the Merger and shall continue in full force and effect for a period six
(6) years from the Effective Time; provided, however, that all rights to
indemnification in respect of any D&O Claim asserted or made within such period
shall continue until the disposition of such D&O Claim.


         (b)      Without limiting the foregoing, in the event any D&O Claim is
brought against any D&O Indemnified Party after the Effective Time arising our
of or pertaining to any action, omission or alleged action or omission occurring
on or prior to the Effective Time in his or her capacity as director or officer
(i) the Acquiror shall retain counsel reasonably satisfactory to D&O Indemnified
Parties and (ii) Acquiror and the Surviving Corporation will use all reasonable
efforts to assist in the vigorous defense of any such matter, provided that
neither Acquiror nor the Surviving Corporation shall be liable for any
settlement of any D&O Claim effected without its written consent, which consent,
however, shall not be unreasonably withheld. Any D&O Indemnified Party wishing
to claim indemnification under this Section 6.23, upon learning of

<PAGE>
                                      -66-

any such D&O Claim, shall notify Acquiror (but the failure so to notify Acquiror
shall not relieve Acquiror from any liability that Acquiror may have under this
Section 6.23 except to the extent such failure materially prejudices Acquiror),
and shall deliver to Acquiror the undertaking contemplated by Section 145(e) of
the Delaware Law. The D&O Indemnified Parties as a group may retain only one law
firm to represent them with respect to each such matter unless there is, under
applicable standards of professional conduct, a conflict on any significant
issue between the positions of any two or more D&O Indemnified Parties.

         SECTION 6.24. Adjustment of Common Stock Exchange Ratio.

         The Common Stock Exchange Ratio shall be subject to adjustment on the
Closing Date as specified in this Section 6.24:

         (a)      At least five Business Days prior to the scheduled Closing
Date, the Company will deliver to Acquiror an unaudited pro forma consolidated
balance sheet, as of the Closing Date (the "Pro Forma Balance Sheet"), prepared
in conformity with GAAP applied on a basis consistent with the preparation of
the Reference Balance Sheet. At the Closing, a Common Stock Exchange Ratio
adjustment shall be made as set forth in the definition of Common Stock Exchange
Ratio. In the event that the Net Receivables Position reflected on the Reference
Balance Sheet exceeds the Net Receivables Position reflected on the Pro Forma
Balance Sheet by at least the Designated Amount, then the amount equal to the
full amount of such change without taking into account the Designated Amount is
defined as the "Deficiency." In the event that the Net Receivables Position
reflected on the Pro Forma Balance Sheet exceeds the Net Receivables Position
reflected on the Reference Balance Sheet by at least the Designated Amount, then
the amount of such change without taking into account the Designated Amount is
defined as the "Surplus."

         SECTION 6.25.  Adjustment of Common Stock Cash Amount.


         The Common Stock Cash Amount shall be subject to adjustment after the
Closing as specified in this Section 6.25:

         (a)      As promptly as practicable, but in any event within sixty
calendar days following the Closing Date, the Company Stockholder shall deliver
to Acquiror the Closing Balance Sheet, together with an unqualified report
thereon of the Company Stockholder's Accountants stating that the Closing
Balance Sheet fairly presents in all material respects the consolidated
financial position of the Company at the Closing Date in conformity with GAAP
applied on a basis consistent with the preparation of the Reference Balance
Sheet. During the preparation of the Closing Balance Sheet by the Company
Stockholder and the periods of any dispute provided for in Section 6.25(b),
Acquiror shall provide the Company Stockholder and the Company Stockholder's
Accountants reasonable access to the books, records, facilities and employees of
the Company, and Acquiror shall cooperate reasonably with the Company
Stockholder's Accountants, in each case to the extent required by the Company
Stockholder and the Company Stockholder's Accountants in order to prepare the
Closing Balance Sheet and to investigate the basis for any such dispute.

<PAGE>
                                      -68-


         (b) (i) Subject to clause (ii) of this Section 6.25(b), the Closing
Balance Sheet delivered by the Company Stockholder to Acquiror shall be deemed
to be and shall be final, binding and conclusive on the parties hereto.

                  (ii) Acquiror may dispute any amounts reflected on the Closing
     Balance Sheet to the extent the net effect of such disputed amounts in the
     aggregate would affect the Net Receivables Position reflected on the
     Closing Balance Sheet by more than the Designated Amount, but only on the
     basis that the amounts reflected on the Closing Balance Sheet were not
     arrived at in accordance with GAAP applied on a basis consistent with the
     preparation of the Reference Balance Sheet; provided, however, that
     Acquiror shall have notified the Company Stockholder and the Company
     Stockholder's Accountants in writing of each disputed item, specifying the
     amount thereof in dispute and setting forth, in reasonable detail, the
     basis for such dispute, within 20 Business Days of the Company
     Stockholder's delivery of the Closing Balance Sheet to Acquiror. In the
     event of such a dispute, Acquiror's Accountants and the Company
     Stockholder's Accountants shall attempt to reconcile their differences, and
     any written resolution by them as to any disputed amounts shall be final,
     binding and conclusive on the parties hereto. If any such resolution by
     Acquiror's Accountants and the Company Stockholder's Accountants leaves in
     dispute amounts the net effect of which in the aggregate would not affect
     the Net Receivables Position reflected on the Closing Balance Sheet by more
     than the Designated Amount, all such amounts remaining in dispute shall
     then be deemed to have been resolved in favor of the Closing Balance Sheet
     delivered by the Company Stockholder to Acquiror. If the Company
     Stockholder's Accountants and Acquiror's Accountants are unable to reach a
     resolution with such effect within 20 Business Days after receipt by the
     Company Stockholder and the Company Stockholder's Accountants of Acquiror's
     written notice of dispute and the items remaining in dispute are such that
     the Common Stock Cash Amount would be adjusted by at least the Designated
     Amount, the Company Stockholder's Accountants and Acquiror's Accountants
     shall submit the items remaining in dispute for resolution to an
     independent accounting firm of international reputation mutually acceptable
     to the Company Stockholder and Acquiror ( such accounting firm being
     referred to herein as the "Independent Accounting Firm"), which shall,
     within thirty Business Days after such submission, determine and report to
     the Company Stockholder and Acquiror upon such remaining disputed items,
     and such written report shall be final, binding and conclusive on the
     Company Stockholder and Acquiror. The fees and disbursements of the
     Independent Accounting Firm shall be allocated between the Company
     Stockholder and Acquiror in the same proportion that the aggregate amount
     of such remaining disputed items so submitted to the Independent Accounting
     Firm that is unsuccessfully disputed by each such party (as finally
     determined by the Independent Accounting Firm) bears to the total amount of
     such remaining disputed items so submitted.

                  (iii) In acting under this Agreement, the Company
     Stockholder's Accountants, Acquiror's Accountants and the Independent
     Accounting Firm shall be entitled to the privileges and immunities of
     arbitrators.

                  (iv) No adjustment to the Common Stock Cash Amount pursuant to
     Section 6.25(c) shall be made with respect to amounts disputed by Acquiror
     pursuant to this Section 6.25(b), unless the net effect of the amounts
     successfully disputed by Acquiror in the aggregate is to decrease the Net
     Receivables Position reflected on the Closing Balance Sheet


<PAGE>
                                      -68-


     by at least the Designated Amount, in which case such adjustment shall be
     made in an amount equal to the full amount successfully disputed.

         (c) The Closing Balance Sheet shall be deemed final for the purposes of
this Section 6.25 upon the earliest of (A) the failure of Acquiror to notify the
Company Stockholder of a dispute within 20 Business Days of the Company
Stockholder's delivery of the Closing Balance Sheet to Acquiror, (B) the written
resolution of all disputes, pursuant to Section 6.25(b)(ii), by the Company
Stockholder's Accountants and Acquiror's Accountants and (C) the written
resolution of all disputes, pursuant to Section 6.25(b)(ii), by the Independent
Accounting Firm. Subject to the limitation set forth in Section 6.25(b)(iv),
within three Business Days of the Closing Balance Sheet being deemed final, a
Common Stock Cash Amount adjustment shall be made as follows:

                  (i) in the event that the Net Receivables Position reflected
     on the Pro Forma Balance Sheet exceeds the Net Receivables Position
     reflected on the Closing Balance Sheet by at least the Designated Amount,
     then the Common Stock Cash Amount shall be adjusted downward in an amount
     equal to the full amount of such change without taking into account the
     Designated Amount, and the Company Stockholder shall, within three Business
     Days of such determination, pay such amount to Acquiror by wire transfer in
     immediately available funds; and

                  (ii) in the event that the Net Receivables Position reflected
     on the Closing Balance Sheet exceeds the Net Receivables Position reflected
     on the Pro Forma Balance Sheet by at least the Designated Amount, then the
     Common Stock Cash Amount shall be adjusted upward in an amount equal to the
     full amount of such change without taking into account the Designated
     Amount and Acquiror shall, within three Business Days of such
     determination, pay the amount of such excess to the Company Stockholder by
     wire transfer in immediately available funds.

         (d) Any payments required to be made by the Company Stockholder or
Acquiror pursuant to Section 6.25(c) shall bear interest from the Closing Date
through the date of payment at the rate of interest publicly announced by
Citibank, N.A. or any successor thereto in New York, New York from time to time
as its prime rate from the Closing Date to the date of such payment.

                                   ARTICLE VII

                              CONDITIONS PRECEDENT

         SECTION 7.01.  Conditions to Obligations of Each Party Under
This Merger Agreement.

         The respective obligations of each party to effect the Merger and the
other transactions contemplated herein shall be subject to the satisfaction at
or prior to the Effective Time of the following conditions, any or all of which
may be waived by agreement of Acquiror and the Company, in whole or in part, to
the extent permitted by applicable Law:

<PAGE>
                                      -69-

         (a) No Order. No Governmental Entity or federal or state court of
competent jurisdiction shall have enacted, issued, promulgated, enforced or
entered any statute, rule, regulation, executive order, decree, judgment,
injunction or other order (whether temporary, preliminary or permanent), in any
case which is in effect and which prevents or prohibits consummation of the
Merger; provided, however, that each of the parties shall use its reasonable
best efforts to cause any such decree, judgment, injunction or other order to be
vacated or lifted and provided further, that the failure to obtain a required
consent or approval of a Governmental Entity (other than those specified in
Section 7.01(b) and Section 7.01(c)) shall not form the basis for an assertion
that this condition is not satisfied.

         (b) HSR Act. The applicable waiting period with respect to the Merger
and the other transactions contemplated hereby, together with any extensions
thereof, under the HSR Act shall have expired or been terminated.

         (c) Certain Governmental Approvals. All consents, waivers, approvals
and authorizations required to be obtained, and all filings or notices required
to be made, by Acquiror or the Company prior to consummation of the transactions
contemplated in this Merger Agreement (other than the filing of the Articles of
Merger in accordance with Delaware Law) shall have been obtained from and made
with the FCC and each of the public utility commissions of the states of
Indiana, Illinois, Wisconsin and Michigan.

         (d) Company Securities. Other than 1,000 shares of Company Common
Stock, there shall be no other securities of the Company outstanding that are
securities convertible into or exchangeable for Company Common Stock or any
other equity securities of the Company and no outstanding options, rights
(preemptive or otherwise), or warrants to purchase or to subscribe for any
shares of such stock or other equity securities of the Company.

         (e) Acquiror's Financing. Acquiror shall have received the Buyer
Financing substantially on the terms contemplated by the Buyer Financing Letters
or alternative financing on terms not materially less favorable to Acquiror than
those set forth in the Buyer Financing Letters.

         SECTION 7.02.  Additional Conditions to Obligations of Acquiror and
Acquiror Sub.

         The obligations of Acquiror and Acquiror Sub to effect the Merger and
the other transactions contemplated herein are also subject to the satisfaction
at or prior to the Effective Time of the following conditions, any or all of
which may be waived by Acquiror, in whole or in part, to the extent permitted by
applicable Law:

         (a) Representations and Warranties. Each and all of the representations
and warranties of the Company and the Company Stockholder contained in this
Merger Agreement shall be true and correct in all material respects as of the
Closing Date as though made as of the Closing Date, except where the failure to
be so true and correct would not have a Company Material Adverse Effect,
considered in the aggregate, except that those representations and warranties
which address matters only as of a particular date shall be true and correct in
all material respects as of such date, except where the failure to be so true
and correct would not have a Company Material Adverse Effect, considered in the
aggregate, and except, in each case,

<PAGE>
                                      -70-

for changes permitted by or consistent with this Merger Agreement; provided,
however, that if any portion of any representation or warranty is already
qualified by the words Company Material Adverse Effect, for purposes of
determining whether this Section 7.02(a) has been satisfied with respect to such
portion of such representation or warranty, such portion of such representation
or warranty as so qualified must be true and correct in all respects. Acquiror
shall have received a certificate of the chief executive officer or chief
financial officer of the Company, on behalf of the Company, to that effect.

         (b) Updated Company Disclosure Schedule. The revised versions of the
Company Disclosure Schedules delivered to Acquiror pursuant to Section 6.04
shall not disclose any Company Material Adverse Effect as compared to such
Sections of the Company Disclosure Schedule as of the date of this Merger
Agreement.

         (c) Agreements and Covenants. The Company and the Company Stockholder
shall have performed or complied in all respects with all agreements and
covenants required by this Merger Agreement to be performed or complied with by
them on or prior to the Effective Time except for such noncompliance that does
not have a Company Material Adverse Effect. Acquiror shall have received a
certificate of the Company Stockholder and the chief executive officer or chief
financial officer of the Company (as to the Company and on its behalf) to that
effect.

         (d) At least 80% of the outstanding principal amount of the Senior
Notes shall have been acquired by the Company or the Reporting Subsidiary, and
the holders of such Senior Notes and the Trustee shall have properly authorized
and approved an amendment to the Indenture, to take effect on the redemption
date, providing for the deletion of certain covenants and other provisions
thereof specified, in writing, by the Acquiror.

         (e) No Challenge. There shall not be pending any enforcement action or
similar proceeding by any Government Entity that is likely to place limitations
on the ownership of shares of Company Common Stock (or shares of common stock of
the Surviving Corporation) by Acquiror or Acquiror Sub such that consummation of
the Merger would violate any provisions of Acquiror's indentures relating to its
outstanding public indebtedness. There shall not be pending any enforcement
action or similar proceeding by any state or federal Governmental Entity that is
likely to have a Company Material Adverse Effect or, if such action arises in
connection with the transactions contemplated hereby, an Acquiror Material
Adverse Effect.

         (f) Company Material Adverse Effect. Since December 31, 1999, there
shall not have occurred a Company Material Adverse Effect (or any development
that, insofar as reasonably can be foreseen, is reasonably likely to result in
any Company Material Adverse Effect) not disclosed in the Company Disclosure
Schedule.

         (g) Ancillary Agreements. Acquiror shall have received, after the date
of this Merger Agreement and on or prior to the Closing Date, (i) an executed
Executive Employment Agreement from at least 80% of the Company Executives; and
(ii) an executed IRU and Maintenance Agreement from Barter Fiber.

Exhibit C (the "Escrow Agreement"), the Company Stockholder shall have agreed to
deposit with the Escrow Agent, such number of shares of Acquiror Common Stock
equal to $25 million divided by the Price Per Share, to be received by him
pursuant to this Agreement, such shares to be held and disposed of as therein
provided.

         (i) Accountants Consent. BDO Seidman, LLP shall have furnished to
Acquiror an undertaking to consent to the use and inclusion of financial
statements relating to the Company and the Subsidiaries audited by it in filings
made by Acquiror subsequent to the Effective Time with the SEC, NASD and state
securities authorities.

         (j) Amendment or Termination of Agreements. The following agreements
shall have been amended or terminated, as appropriate: (i) the Expense Sharing
Agreement dated February 1, 1997 between the Reporting Subsidiary and RVP
Development shall be terminated without liability; (ii) the Corporate Aircraft
Lease between the Reporting Subsidiary and RVP Leasing Company, Inc. shall be

of control with respect to the Reporting Subsidiary and (z) to amend Section 22
of such Lease to provide the Tenant (as defined therein) the right to sublease
all or any part of the Leased Premises (as defined therein) after a change of
control with the permission of the Landlord (as defined therein) which
permission shall not be unreasonably withheld or delayed; (iv) the Equipment
Lease dated October 1, 1999, by and between the Reporting Subsidiary and RVP
Development Corporation shall be modified in the following manner: (y) to amend
such Equipment Lease to provide for an attachment consisting of an itemized list
of all of the Leased Equipment (as defined therein), and (z) to amend Section 11
of such Equipment Lease to include a dollar amount that the Company reasonably
determines will represent the fair market value of the Leased Equipment at the
expiration of the term of such Equipment Lease; and (v) RVP Development, Inc.
shall assign to Acquiror its entire right, title and interest in each Memorandum
of Agreement with Engineering Protection Systems, Inc. referenced in Section
3.14 of the Company Disclosure Schedules or, at the election of Acquiror, each
such Memorandum of Agreement shall be terminated without liability and
Engineering Protection Systems, Inc. shall agree to enter into a new Agreement

         (a) Representations and Warranties. Each and all of the representations
and warranties of Acquiror and Acquiror Sub contained in this Merger Agreement
shall be true and correct as of the date of this Merger Agreement and shall be
true and correct in all material respects as of the Closing Date as though made
as of the Closing Date, except where the failure to be so true and correct would
not have an Acquiror Material Adverse Effect, considered in the aggregate,
except that those representations and warranties which address matters only as
of a particular date shall be true and correct as of such date, except where the
failure to be so true and correct would not have an Acquiror Material Adverse
Effect, considered in the aggregate, and except, in each case, for changes
permitted by or consistent with this Merger Agreement; provided, however, that
if any portion of any representation or warranty is already qualified by the
words Acquiror Material Adverse Effect, for purposes of determining whether this
Section 7.03(a) has been satisfied with respect to such portion of such
representation or warranty, such portion of such representation or warranty as
so qualified must be true and correct in all respects. The Company shall have
received a certificate of the chief executive officer or chief financial officer
of Acquiror, on behalf of Acquiror, to that effect.

         (b) Agreements and Covenants. Acquiror and Acquiror Sub shall have
performed or complied in all respects with all agreements and covenants required
by this Merger Agreement to be performed or complied with by them on or prior to
the Effective Time except for such noncompliance that does not have an Acquiror
Material Adverse Effect. The Company shall have received a certificate of the
chief executive officer or chief financial officer of Acquiror and Acquiror Sub,
on behalf of Acquiror and Acquiror Sub, to that effect.

         (c) Acquiror Material Adverse Effect. Since December 31, 1999, there
shall not have occurred an Acquiror Material Adverse Effect (or any development
that, insofar as reasonably can be foreseen, is reasonably likely to result in
any Acquiror Material Adverse Effect) not disclosed in the Acquiror Disclosure
Schedule.

         (d) No Challenge. There shall not be pending any enforcement action or
similar proceeding by any Government Entity that is likely to place limitations
on the ownership of shares of Company Common Stock (or shares of common stock of
the Surviving Corporation) by Acquiror or Acquiror Sub such that consummation of
the Merger would violate any provisions of Acquiror's indentures relating to its
outstanding public indebtedness. There shall not be pending any enforcement
action or similar proceeding by any state or federal Governmental Entity that is
likely to have an Acquiror Material Adverse Effect or, if such action arises in
connection with the transactions contemplated hereby, a Company Material Adverse
Effect.

         (e) Ancillary Agreements.  The Company Stockholder shall have received,
on or prior to the Closing Date, copies of (i) an executed IRU and Maintenance

to terminate this Merger Agreement under this Section 8.01(d) shall not be
available to (i) Acquiror, where Acquiror's willful failure to fulfill any
obligation under this Merger Agreement has been the cause of, or resulted in,
the failure of the Effective Time to occur on or before such date, or (ii) the
Company, where the Company's willful failure to fulfill any obligation under
this Merger Agreement has been the cause of, or resulted in, the failure of the
Effective Time to occur on or before such date; or

August 12, 2000 and Acquiror, in its sole discretion, elects not to fund any
further operating losses of the Company and the Subsidiaries; provided that
Acquiror may not exercise its rights under this clause (e) if the Company
notifies Acquiror in writing prior to August 12, 2000 that the Company
Stockholder will fund any such operating losses of the Company between August
12, 2000 and the earlier of the Closing Date or the termination of this Merger
