                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                   (UNAUDITED)

1. BUSINESS AND ORGANIZATION

     PentaStar Communications, Inc., a Delaware corporation ("PentaStar" or the
"Company"), was founded on March 15, 1999, to become a multi-regional company
that designs, sells and facilitates the installation and usage of communications
services for small and medium-size business customers. On October 26, 1999
PentaStar, through its wholly-owned subsidiaries, acquired the outstanding
capital stock and other equity interests of DMA Ventures, Inc., dba Access
Communications ("Access") and ICM Communications Integration, Inc. ("ICM") and
completed an initial public offering of its common stock (the "Offering").

     Upon closing of the acquisitions of Access, ICM and the Offering, PentaStar
commenced its business operations as a sales agent for communications services
including local access, long distance, wireless and internet services for voice
and data communications. PentaStar designs, procures and facilitates the
installation and use of communications services to best meet its customers'
specific needs. In the first quarter of fiscal 2000 the Company acquired four
communications services agents to expand its operations (see Note 5).

     The financial statements as of and for the three months ended March 31,
2000, are unaudited and prepared by the Company pursuant to the interim
reporting rules and regulations of the Securities and Exchange Commission;
however, the financial statements include all adjustments (consisting of normal
recurring adjustments) considered necessary by management for a fair
presentation of the financial position and results of operations for the period.
The results of operations for interim periods are not necessarily indicative of
the results that may be expected for the entire year. The accompanying
statements of operations and cash flows do not include a comparative period for
1999 as the Company had no operations in that period.

     In December 1999, the staff of the Securities and Exchange Commission
released Staff Accounting Bulletin ("SAB") No. 101 "Revenue Recognition". SAB
No. 101 provides interpretive guidance on the recognition, presentation and
disclosure of revenue in financial statements. The Company's accounting policies
are consistent with the guidance provided in SAB No. 101 and its implementation
in the second quarter of fiscal 2000 is not expected to have a significant
effect on the results of operations or financial position of the Company.

3. INVENTORIES

     Inventories consist of finished goods and refurbished and used equipment
held for resale in the ordinary course of business. Inventories are carried at
the lower of cost or market. Cost is determined on a FIFO (first-in, first-out)
basis.

4. EARNINGS PER SHARE

     The Company applies SFAS No. 128, "Earnings Per Share". SFAS No. 128
provides for the calculation of "Basic" and "Diluted" earnings or net income per
share. Basic net income per share includes no dilution and is computed by
dividing earnings available to common shareholders by the weighted average
number of common shares outstanding for the period. Diluted net income per share
reflects the potential dilution of stock options and warrants using the treasury
stock method. Outstanding options and warrants exercisable into 113,750 shares
of common stock have been excluded from the calculation of diluted loss per
share as they are antidilutive.

5. BUSINESS COMBINATIONS

     In the first quarter of fiscal 2000, PentaStar completed the acquisition of
four communications services agents. Following is a summary of the acquisitions.

     PentaStar, through a wholly-owned subsidiary, acquired the assets of
USTeleCenters, Inc. and Vermont Network Services Corporation (collectively
referred to as "UST"). UST, founded in 1986 and headquartered in Boston,
Massachusetts, is a full-service communications agent focusing on small business
customers located throughout Bell Atlantic's 13 state Northeast and Mid-Atlantic
region. UST has agency agreements with service providers including Bell
Atlantic, Bell South, Southwestern Bell and Sprint. The purchase consideration
consisted of $277 in cash including acquisition costs, the issuance of 5,980
shares of the Company's common stock with a fair market value of $100 and the
assumption of liabilities.

     PentaStar, through a wholly-owned subsidiary, acquired the assets of NCI
Communications, Inc. ("NCI"). NCI is primarily a long distance communications
services agent located in Seattle, Washington. NCI has agency agreements with
Qwest, AT&T and GST Telecom. NCI was owned by certain of the previous
shareholders of ICM, who, upon the Company's acquisition of ICM, became
shareholders of the Company. The purchase consideration consisted of $18 in cash
including acquisition costs and the cancellation of a $601 note receivable from
NCI to PentaStar.

     PentaStar acquired ParTel, Inc. ("ParTel") by merger. ParTel, founded in
1982, is a full-service communications agent based in Phoenix, Arizona primarily
servicing customers in the Phoenix and Tucson metropolitan markets. ParTel is an
agent of U S WEST and sells primarily high-end, data-oriented products. The
initial purchase consideration consisted of $606 in cash including acquisition
costs and the issuance of 30,310 shares of the Company's common stock with a
fair market value of $539. In addition, the agreement provides for additional
consideration in the form of cash and the Company's common stock if certain
operating performance criteria are met by ParTel for the year ending December
31, 2000.

     PentaStar, through a wholly-owned subsidiary, acquired Resource
Communications, Inc. ("Resource") by merger. Resource, based in Dublin,
California, is a full-service communications agent, which furnishes
communication solutions to customers in Northern California. Resource is one of
the largest Cable & Wireless long distance master agents and a significant
Pacific Bell authorized sales representative. The initial purchase consideration
consisted of $1,037 of cash including acquisition costs and the issuance of
81,250 shares of the Company's common stock. Of the 81,250 of issued shares,
50,000 shares with a fair market value of $919 were placed in an indemnification
escrow until March 31, 2001. The remaining 31,250 shares were placed in escrow
until March 15, 2001 to be released upon Resource attaining certain performance
criteria for the year ending December 31, 2000. As a result, the fair market
value of the 31,250 shares has not been reflected in the initial purchase
consideration. At the time the performance criteria is met, the additional
consideration will be treated as goodwill and recorded on the balance sheet. In
addition, the agreement provides for additional consideration in the form of
cash and the Company's common stock if certain operating performance criteria
are met by Resource for the period from January 1, 2000 to June 30, 2001.

     The acquisitions discussed above were recorded using the purchase method of
accounting by which the purchase consideration was allocated to the identifiable
assets and liabilities of the acquired companies and the excess of the purchase
consideration over the fair value of the net assets acquired was recorded as
goodwill. The allocation of the purchase consideration was as follows:



<TABLE>
<S>                                <C>
Purchase Consideration:
Cash .........................     $1,681
PentaStar common stock .......      1,558
Acquisition costs ............        257
                                   ------
                                   $3,496
                                   ======
</TABLE>

     Of the total purchase consideration of $3,496, $1,132 was allocated to
property and equipment, ($1,223) to net working


                                      F-6
<PAGE>   10


capital, ($166) to noncurrent liabilities and $3,753 to goodwill. The financial
statements reflect a preliminary allocation of the purchase price, to be
finalized upon evaluation of certain assets and liabilities acquired. Goodwill
will be amortized over a twenty year period. The difference between the results
of operations subsequent to the closing of each transaction and the results of
operations assuming each transaction was closed on January 1, 2000, is not
significant.

     In addition to the above acquisition terms, certain shareholders of the
acquired companies have entered into escrow and contingent stock agreements with
PentaStar upon closing of the acquisitions. These agreements adjust the final
consideration paid to those shareholders in return for their interest in their
acquired companies. Under these agreements, shares of PentaStar common stock
were placed into escrow. Based upon the earnings performance of an acquired
company relative to that of all other acquired companies for the 12-month period
prior to the earlier of a sale of substantially all of the assets or stock of
PentaStar or five years, the shareholder associated with that company will
receive back from escrow all, some or none of the shares placed in escrow. In
addition, based again upon the relative earnings performance of the acquired
company, that shareholder may receive additional shares of common stock from
PentaStar. The agreements are designed, however, so that there will be no net
change to the total number of shares of PentaStar common stock outstanding after
the combined adjustments are made for all of the acquired companies.

     In connection with the acquisition of ParTel, the Company advanced $500 to
Par.com, Inc. ("Par.com"). Par.com is a corporation controlled by the former
shareholders of ParTel. The promissory note bears interest at the prime rate
plus 1%. The principal and accrued interest is due on December 31, 2001, unless
the Company becomes obligated to make payment under the earnout provisions of
the ParTel acquisition agreement, at which time the required obligation would be
applied to payment on the promissory note. The promissory note is secured by a
security and pledge agreement whereby the assets of Par.com and the Company's
common stock issued in the acquisition are collateral to secure payment under
the promissory note. Certain former shareholders of ParTel have also personally
guaranteed payment.

6. SUBSEQUENT EVENTS

     In the first quarter of fiscal 2000, the Company signed a definitive
agreement to acquire the assets of Eastern Telecom, Inc. ("ETI"). ETI, founded
in 1992, is a full-service communications agent based in Warwick, Rhode Island
primarily servicing customers in Boston, New York, Albany, Providence and
Warwick. ETI is an authorized agent for Bell Atlantic and Bell South. The
acquisition of the assets of ETI is contingent upon receipt of the approval of
the shareholders of VSI Enterprises, Inc., which is the parent company of ETI.
Terms of the definitive agreement provide for a purchase price for the assets to
consist of approximately $2,100 in cash, the issuance of the Company's common
stock with a fair market value of $950 and the assumption of certain liabilities
at closing. In addition, there is a potential earnout payment based upon the
combined earnings of ETI and UST for the year ending December 31, 2000. The
acquisition is expected to close in May 2000.

     In the second quarter of fiscal 2000, PentaStar signed a definitive
agreement to acquire the Network Services Group of Telecomm Industries Corp.
("TCMM"). TCMM's Network Services Group is Ameritech's largest distributor of
voice and data services. TCMM is also an authorized distributor for BellSouth.
Under the terms of the purchase agreement, the consideration for the transaction
is approximately $7.1 million in the Company's common stock and cash, the
assumption of $6.2 million in debt and the assumption of certain operating
liabilities. Approximately $4.5 million of the debt assumed is secured by $6.2
million of the future commissions, due to PentaStar from the existing Ameritech
contracts, which will be realized over the next several years. In addition,
there are potential earnout payments to TCMM based upon certain operating
performance criteria during the period from April 1, 2000 through March 31,
2001.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS

     The following discussion and analysis of financial condition and results of
operations should be read in conjunction with the consolidated financial
statements and related notes as of and for the three months ended March 31,
2000. The statements of operations and cash flows for the three months ended
March 31, 2000 included in the financial statements do not include a comparative
period for 1999 as a result of PentaStar having no operations during the three
months ended March 31, 1999. Accordingly, the following discussion does not
include a comparison to a prior year period.

OVERVIEW

     PentaStar was incorporated on March 15, 1999 under Delaware law. Through
the acquisitions of existing communications services agents in major
metropolitan areas, we have become a leading communications services agent for
communications services including local access, long distance, wireless and
Internet services for voice and data communications. We design, procure and
facilitate the installation and use of communications services to best meet our
customers' needs. We currently act as a sales agent for Bell Atlantic, US WEST
Communications, Cable & Wireless, Pacific Bell, BellSouth, Southwestern Bell,
Sprint, Qwest, Epoch Internet and other communications services providers. We
plan to continue to acquire other communications services agents and to enter
into agency agreements with other communications services providers.

     Substantially all of our revenues are generated from the commissions we
receive from selling communications services as agents for communications
service providers. We are paid a commission by each service provider. Currently
we primarily sell advanced communications services and basic dial tone services
for the local access market to facilitate data, voice and video communications.
We expect that, over time, the percentage of advanced communications services
revenues will increase as a percentage of revenues because of increased demand
for, and availability of, these services. Basic dial tone services in general
are telephone connections, voice messaging and call management services.
Advanced communications services are all other voice and data communications
services, including:


                                       2
<PAGE>   12


     o    data transmission oriented services;

     o    dedicated high-capacity transmission services;

     o    high speed real time communications access, including digital
          subscriber line, or DSL;

     o    packet-based transmission for wide area networks, including frame
          relay service; and

     o    an advanced digital network for data, video, voice and Internet
          traffic, including ISDN.

     In addition to acting as a sales agent for local access, long distance,
wireless and Internet, we also offer, to a limited extent, products such as
telephone equipment and the related hardware installation.

     Salaries and commissions expenses consist principally of salary and
incentive compensation that our operating companies pay their sales and
marketing, operations and engineering support and administrative staff.

     Cost of product sales consists of the cost of the product sold and any
subcontract labor incurred in installing the equipment.

     Other general and administrative expenses include communications expenses,
office rent and utilities, travel and marketing for the operating companies.
These expenses also include the operations and staffing related to our corporate
office.

     We experience some seasonal variations in our businesses. Orders for
communications services tend to slow in the last quarter of the calendar year
due to customers' budgetary constraints. Generally, orders increase in the first
quarter of the following year. Because of the time lag between order and
installation, revenues in the first four months of each calendar year are
typically below the average of revenues for the remaining portion of the year.

Recent Acquisitions.

     In the first quarter of fiscal 2000, we completed the acquisition of or
signed definitive agreements to acquire six communications services agents.
Following is a summary of our acquisition activity.

     PentaStar, through a wholly-owned subsidiary, acquired the assets of
USTeleCenters, Inc. and Vermont Network Services Corporation (collectively
referred to as "UST"). UST, founded in 1986 and headquartered in Boston,
Massachusetts, is a full-service communications agent focusing on small business
customers located throughout Bell Atlantic's 13 state Northeast and Mid-Atlantic
region. UST has agency agreements with service providers including Bell
Atlantic, Bell South, Southwestern Bell and Sprint. The purchase consideration
consisted of $277,000 in cash including acquisition costs, the issuance of 5,980
shares of the Company's common stock with a fair market value of $100,000 and
the assumption of liabilities.

     PentaStar, through a wholly-owned subsidiary, acquired the assets of NCI
Communications, Inc. ("NCI"). NCI is primarily a long distance communications
services agent located in Seattle, Washington. NCI has agency agreements with
Qwest, AT&T and GST Telecom. NCI was owned by certain of the previous
shareholders of ICM, who, upon the Company's acquisition of ICM, became
shareholders of the Company. The purchase consideration consisted of $18,000 in
cash including acquisition costs and the cancellation of a $601,000 note
receivable from NCI to PentaStar.

     PentaStar acquired ParTel, Inc. ("ParTel") by merger. ParTel, founded in
1982, is a full-service communications agent based in Phoenix, Arizona primarily
servicing customers in the Phoenix and Tucson metropolitan markets. ParTel is an
agent of U S WEST and sells primarily high-end, data-oriented products. The
initial purchase consideration consisted of $606,000 in cash including
acquisition costs and the issuance of 30,310 shares of the Company's common
stock with a fair market value of $539,000. In addition, the agreement provides
for additional consideration in the form of cash and the Company's


                                       3
<PAGE>   13


common stock if certain operating performance criteria are met by ParTel for the
year ending December 31, 2000.

     PentaStar, through a wholly-owned subsidiary, acquired Resource
Communications, Inc. ("Resource") by merger. Resource, based in Dublin,
California, is a full-service communications agent, which furnishes
communication solutions to customers in Northern California. Resource is one of
the largest Cable & Wireless long distance master agents and a significant
Pacific Bell authorized sales representative. The initial purchase consideration
consisted of $1,037,000 of cash including acquisition costs and the issuance of
81,250 shares of the Company's common stock. Of the 81,250 of issued shares,
50,000 shares with a fair market value of $919,000 were placed in an
indemnification escrow until March 31, 2001. The remaining 31,250 shares were
placed in escrow until March 15, 2001 to be released upon Resource attaining
certain performance criteria for the year ending December 31, 2000. In addition,
the agreement provides for additional consideration in the form of cash and the
Company's common stock if certain operating performance criteria are met by
Resource for the period from January 1, 2000 to June 30, 2001.

     In the first quarter of fiscal 2000, PentaStar signed a definitive
agreement to acquire the assets of Eastern Telecom, Inc. ("ETI"). ETI, founded
in 1992, is a full-service communications agent based in Warwick, Rhode Island
primarily servicing customers in Boston, New York, Albany, Providence and
Warwick. ETI is an authorized agent for Bell Atlantic and Bell South. The
acquisition of the assets of ETI is contingent upon receipt of the approval of
the shareholders of VSI Enterprises, Inc., which is the parent company of ETI.
Terms of the definitive agreement provide for a purchase price for the assets to
consist of approximately $2,100,000 in cash, the issuance of the Company's
common stock with a fair market value of $950,000 and the assumption of certain
liabilities at closing. In addition, there is a potential earnout payment based
upon the combined earnings of ETI and UST for the year ending December 31, 2000.
The acquisition is expected to close in May 2000.

     In the second quarter of fiscal 2000, PentaStar signed a definitive
agreement to acquire the Network Services Group of Telecomm Industries Corp
("TCMM"). TCMM's Network Services Group is Ameritech's largest agent and a
distributor of voice and data services. TCMM is also an authorized distributor
for BellSouth. Under the terms of the purchase agreement, the consideration for
the transaction is approximately $7.1 million in the Company's common stock and
cash, the assumption of $6.2 million in debt and the assumption of certain
operating liabilities. Approximately $4.5 million of the debt assumed is secured
by $6.2 million of future commissions, due to PentaStar from the existing
Ameritech contracts, which will be realized over the next several years. In
addition, there are potential earnout payments to TCMM based upon certain
operating performance criteria during the period from April 1, 2000 through
March 31, 2001.


RESULTS OF OPERATIONS

FOR THE THREE MONTHS ENDED MARCH 31, 2000

     Revenues. Revenues consist principally of commissions from sales of
communications services as an agent for communications services providers. We
recorded revenue of $2,418,000 resulting from sales of advanced communications
services, $1,715,000 from sales of basic dial tone services and $307,000 from
product sales. The acquisitions of UST, NCI, ParTel and Resource contributed
significantly to the overall revenue levels. The acquisition of UST provided us
with a telemarketing sales division. The telemarketing group focuses on high
volume, lower revenue services, which accounts for the significant amount of
basic dial tone services revenues recorded in the three months ended March 31,
2000.

     Costs and expenses. Salaries and commissions expense of $3,875,000 consists
principally of costs of operations, sales, management and administrative
personnel at the operating companies. Cost of product sales of $131,000 consists
of the cost of the equipment and subcontract labor attributable to the product
sales. Other general and administrative expenses of $977,000 consists
principally of the overhead expenses of the operating companies such as rent,
telephone and supplies and the expenses applicable to our corporate office such
as personnel costs, travel, insurance and professional fees. Depreciation and
amortization expense of $295,000 consists of depreciation expense on the
property and equipment and the amortization of goodwill associated with the
acquisitions of the operating companies in fiscal 1999 and in the first quarter
of fiscal 2000.


                                       4
<PAGE>   14


     Loss from operations. A loss from operations of $838,000 was recognized for
the three months ended March 31, 2000.

     Other (income) expense, net. Other income, net, of $98,000 consists of
$103,000 of interest income earned on our invested cash. As we utilize
additional cash resources for operating needs and future acquisitions, we expect
interest income to decrease. Interest expense includes interest expense on
capital lease obligations assumed in the acquisition of UST.

     Income taxes. A benefit of $239,000 was recorded for the period
representing an effective tax rate of 32.3%. The difference between the federal
statutory rate of 34% and the effective rate is due to state income taxes offset
by nondeductible goodwill amortization.

     Net loss. A net loss of $501,000 was recognized for the three months ended
March 31, 2000.

LIQUIDITY AND CAPITAL RESOURCES

     Our operations used net cash of $860,000 for the three months ended March
31, 2000 which was primarily attributable to the net loss recognized during the
period and the payment of accounts payable and accrued liabilities. The
acquisition of UST included the assumption of approximately $2,441,000 in
current liabilities. This use of cash primarily represents the payment of these
assumed liabilities.

     We used cash of $2,351,000 in investing activities for the three months
ended March 31, 2000 as a result primarily of our acquisition activity, the
issuance of a promissory note and the purchase of property and equipment. We
used cash of $1,742,000 to fund the cash consideration used to acquire UST, NCI,
ParTel and Resource in the first quarter of fiscal 2000 and to also pay the
remaining amounts due to the shareholders of our 1999 acquisitions of DMA
Ventures, Inc. dba Access Communications and ICM Communications Integration,
Inc. In connection with the acquisition of ParTel, we issued a promissory note
in the amount of $500,000 to a corporation controlled by the former shareholders
of ParTel. The principal and accrued interest is due no later than December 31,
2001. Property and equipment of $101,000 was purchased for the three months
ended March 31, 2000.

     Our financing activities for the three months ended March 31, 2000 used
cash of $19,000 for payments on capital lease obligations.

     We intend to fund future acquisitions through the remaining proceeds of our
initial public offering, the issuance of common stock, internally generated cash
flow and future borrowings.

     As of March 31, 2000, we had no outstanding debt. We believe we will be
able to obtain a working capital line of credit or other debt financing,
however, we may not be able to obtain this financing, or, if available, the
terms of the financing may not be favorable to us or the shareholders without
substantial dilution of ownership rights.

     We believe that the net proceeds from the initial public offering, cash
flow from operations and future debt financing will be sufficient to satisfy our
anticipated cash requirements for the next twelve months. We will likely require
additional equity or debt financing beyond that period, and possibly sooner,
dependent upon the scope of the acquisition activity. We have not yet identified
any sources of long-term financing.

YEAR 2000 RISKS

     Many software applications and computer hardware and related equipment and
systems that use embedded technology, such as microprocessors, rely on two
digits rather than four to represent years in performing computations and
decision-making functions. These programs, hardware items and systems may fail
beginning on January 1, 2000, or earlier, because they misinterpret "00" as the
year 1900 rather than 2000. This problem is generally referred to as the "Year
2000" issue.


                                       5

<PAGE>   15


     As of May 8, 2000, there were no material Year 2000 issues noted with any
of our computer systems, or to our knowledge, to any third party that we do
business with. No costs are expected to be incurred or accrued relating to the
Year 2000 issue.

RECENT ACCOUNTING PRONOUNCEMENTS

     In December 1999, the staff of the Securities and Exchange Commission
released Staff Accounting Bulletin ("SAB") No. 101 "Revenue Recognition". SAB
No. 101 provides interpretive guidance on the recognition, presentation and
disclosure of revenue in financial statements. The Company's accounting policies
are consistent with the guidance provided in SAB No. 101 and its implementation
in the second quarter of fiscal 2000 is not expected to have a significant
effect on the results of operations or financial position of the Company.

ITEM 2.   CHANGES IN SECURITIES

          (c.) During the period from January 1, 2000 through March 31, 2000,
               PentaStar sold unregistered securities as follows:

               o    On February 18, 2000, PentaStar issued 5,980 shares of

Communications Integration, Inc., a Washington corporation (the "Company"), and
the Persons identified on the signature page hereto as Shareholders
(individually, a "Shareholder" and collectively, the "Shareholders").

                                    Recitals

          A.   The Shareholders own all of the issued and outstanding capital
stock of the Company.

          B.   The Acquiror is a newly-formed, wholly-owned subsidiary of
PentaStar. The Acquiror desires to acquire from the Company, and the Company
desires to sell to the Acquiror, substantially all of the Company's assets as
provided in this Agreement.

          C.   PentaStar, the Acquiror, the Company and the Shareholders desire
to make certain representations, warranties and agreements in connection with
such transaction and also desire to set forth various conditions precedent
thereto.

                                    Agreement

          NOW, THEREFORE, in consideration of the premises, the mutual
representations, warranties and covenants set forth herein and other good and
valuable consideration, the receipt and sufficiency of which are acknowledged,
the parties agree as follows:

1.   Definitions. The terms defined in Exhibit 1.1(a) shall have the meanings
designated therein.

2.   Purchase and Sale.

     2.1. Basic Transaction. Subject to the terms and conditions set forth in
this Agreement, the Acquiror agrees to purchase from the Company, and the
Company agrees to sell to the Acquiror, all the Acquired Assets free and clear
of any Encumbrance or Tax, for the consideration specified in Section 2.3. The
Acquiror will have no obligation under this Agreement to purchase less than all
of the Acquired Assets.

     2.2. Assumption of Certain Liabilities. Subject to the terms and conditions
set forth in this Agreement, the Acquiror agrees to assume and become
responsible at the Closing for all of the Assumed Liabilities. The Acquiror will
not assume or have any responsibility with respect to any other Liability not
expressly included within the definition of Assumed Liabilities.

     2.3. Purchase Price; Payment.

          (a)  The consideration payable by the Acquiror to the Company for the
Acquired Assets will be (i) cash in an amount of $10,000, (ii) the termination
as of the Closing Date (pursuant to Section 5.9) of the NCI Liabilities and
(iii) the assumption of the Assumed Liabilities (collectively the "Purchase
Price"). On the Closing the Acquiror will pay to the Company by wire transfer to
an account designated by the Company in cash the amount of the cash portion of

<PAGE>   6

          (b)  The allocation of the total consideration for the Acquired Assets
for Tax reporting purposes shall be as follows: (i) to cash and cash
equivalents, the amount thereof; (ii) to Closing Accounts Receivable, the amount
determined by the Acquiror from the Company's records, adjusted by the Acquiror
to conform to GAAP; (iii) to inventory, the amount determined by the Acquiror
from the Company's records, adjusted by the Acquiror to conform to GAAP; (iv) to
leasehold improvements, the greater of fair market value (determined by the
Acquiror from its historical experience, or in the Acquiror's sole discretion,
by independent appraisal) or the current book value thereof as reflected in the
Company's records, adjusted by the Acquiror to conform to GAAP; and (v) the
entire remaining balance of the consideration shall be allocated to the goodwill
of the Company's business or, at the Acquiror's sole discretion, to the other
intangible assets which are included in the Acquired Assets. The parties
acknowledge that such allocations for Tax reporting purposes were determined
pursuant to arm's length bargaining regarding the fair market values of the
Acquired Assets in accordance with the provisions of Code Section 1060. The
parties agree to be bound by these allocations for all federal, state and local
Tax reporting purposes, including for purposes of determining any income, gain,
loss, depreciation or other deductions in respect of such assets. The parties
further agree to prepare and file all Tax Returns (including Form 8594 under the
Code) in a manner consistent with such allocations. If the Acquiror makes
adjustments to conform to GAAP pursuant to clauses (ii), (iii) or (iv) above,
the Acquiror will bear any out-of-pocket expense of making such adjustments.

     2.4. Sales Taxes, Etc. The Company will pay all sales, use, transfer,
licensing and other Taxes, fees and charges payable in respect of or as a result
of the sale and transfer of the Acquired Assets to the Acquiror pursuant to this
Agreement.

     2.5. The Closing. The closing of the transactions contemplated by this
Agreement (the "Closing") shall take place at the offices of Sherman & Howard
L.L.C. at 10:00 a.m. Denver, Colorado time on January 7, 2000 or as soon
thereafter as possible. PentaStar may, at any time, waive any unsatisfied
closing conditions specified in Section 6.1 and, upon payment by the Acquiror of
the $10,000 cash portion of the Purchase Price and execution by the Acquiror of
the Assignment and Assumption Agreement, the Closing shall be deemed to have
occurred, and all of the Company's right, title and interest to the Acquired
Assets shall be deemed conveyed to the Acquiror. All transactions contemplated
by this Agreement will be effective at 12:00 a.m. local time in Seattle,
Washington on the day of the Closing (such effective time being the "Closing
Date").

deliver to PentaStar the various certificates, instruments and documents, and
take the actions, referred to in Section 6.1 and (b) PentaStar will deliver to
the Company the various certificates, instruments and documents, and take the
actions, referred to in Section 6.2.

The Company and the Shareholders each represent and warrant to PentaStar that
the statements contained in this Section 3.1 are correct and complete as of the

               (ii) As of the Closing, the Company will, after giving effect to
the assumption of the Assumed Liabilities and the termination of the NCI

          (e)  Absence of Certain Agreements, Changes or Events. The Company is
not, except as set forth on Exhibit 3.1(e)(i), a party to or otherwise bound by
any material contract or agreement (i) pursuant to which the Company is
obligated to furnish any services, product or equipment and (ii) that has been

amount of their respective normal annualized salaries due and payable during
such period); or (x) agreed to incur, take, enter into, make or permit any of
the matters described in clauses (i) through (ix).

          (f)  Tax Matters.

               (i)  The Company has filed all Tax Returns that it was required
to file. All such Tax Returns were correct and complete in all material
respects. To the best knowledge of the Company and the Shareholders, all
material Taxes due and owing by the Company (whether or not shown on any Tax
Return) have been paid. The Company is not currently the beneficiary of any
extension of time within which to file any Tax Return. No claim has ever been
made by an authority in a jurisdiction where the Company does not file Tax
Returns that it is or may be subject to taxation by that jurisdiction. There are
no Encumbrances on any of the assets of the Company that arose in connection
with any failure (or alleged failure) to pay any Tax.

               (ii) To the best knowledge of the Company and the Shareholders,
the Company has withheld and paid all Taxes required to have been withheld and
paid in connection with amounts paid or owing to any employee, independent
contractor, creditor, shareholder or other third party.

               (iii) To the best knowledge of the Company and the Shareholders,
there is no basis for any authority to assess any additional Taxes for any
period for which Tax Returns have been filed. There is no pending or threatened
dispute or claim concerning any Tax Liability of the Company. Exhibit
3.1(f)(iii) lists all federal, state, local and foreign income Tax Returns
(except federal payroll Tax Returns) filed with respect to the Company for
taxable periods ended on or after December 31, 1992, indicates those Tax Returns
that have been audited and indicates those Tax Returns that currently are the
subject of audit. To the best knowledge of the Company and the Shareholders, the
Shareholders have delivered to PentaStar correct and complete copies of all
federal income Tax Returns, examination reports, and statements of deficiencies
filed or assessed against or agreed to by the Company since December 31, 1992.

               (iv) The Company has not waived any statute of limitations in
respect of Taxes or agreed to any extension of time with respect to a Tax
assessment or deficiency.

               (v)  Neither the Company nor any of its shareholders has ever
filed (A) an election pursuant to Section 1362 of the Code that the Company be
taxed as an "S" corporation, except as set forth on Exhibit 3.1(f)(v), or (B) a
consent pursuant to Section 341(f) of the Code relating to collapsible
corporations. The Company has not made any payments, is not obligated to make
any payments and is not a party to any agreement that under certain
circumstances could obligate it to make any payments that will not be deductible
under Code Section 280G. The Company has not been a United States real property
holding corporation within the meaning of Code Section 897(c)(2) during the
applicable period specified in


                                      -5-
<PAGE>   10


Code Section 897(c)(1)(A)(ii). The Company has disclosed on its federal income
Tax Returns all positions taken therein that could give rise to a substantial
understatement of federal income Tax within the meaning of Code Section 6662.
The Company is not a party to any Tax allocation or sharing agreement. The
Company has not been a member of an Affiliated Group filing a consolidated
federal income Tax Return (other than a group the common parent of which was the
Company) and has no Liability for the Taxes of any Person (other than the
Company) under Treasury Regulation Section 1.1502-6 (or any similar provision of
state, local, or foreign law), as a transferee or successor, by contract or
otherwise.

               (vi) Exhibit 3.1(f)(vi) sets forth the following information with
respect to the Company as of the most recent practicable date: (A) the basis of
the Company in its assets; and (B) the amount of any net operating loss, net
capital loss, unused investment or other credit, unused foreign tax credit or
excess charitable contribution allocable to the Company.

          (g)  Assets and Properties.

               (i)  The Company has good and marketable title to, or a valid
leasehold interest or interest as a licensee in, the properties and assets used
or held for use by it, located on its Premises, or shown on the Latest Balance
Sheet or acquired after the date thereof. As of the Closing, all of the Acquired
Assets will be owned by the Company, free and clear of all Encumbrances except
for the Assumed Liabilities; provided, however, that PentaStar and the Acquiror
hereby acknowledge and agree that the Company has not trademarked its name or
"NCI" and has not performed or requested a trademark search. Accordingly, it is
possible some other Person has trademarked the Company name or "NCI" or some
form thereof and the Company does not warrant that there are no other Persons
using its name, except that the Company does represent and warrant that it has
not granted any Person the right to use the Company's name or "NCI" or any
deviation thereof. Since November 30, 1999, the Company has not entered into any
contract or made any commitment to sell all or any part of its assets. The
Acquired Assets constitute all of the real, personal and mixed assets and
property, both tangible and intangible, including Intellectual Property, which
are being used or held for use by the Company in the conduct of the business and
operations of the Company, consistent with historical and current practices. The
Company owns or leases all equipment and other tangible assets necessary for the
conduct of its business as presently conducted. Each such tangible asset
material to the Company's operations has been maintained in accordance with
normal industry practice and is in good operating condition and repair (subject
to normal wear and tear). All leases of real property between the Company and
any Shareholder, officer or director or any relative or affiliate thereof are on
fair market terms (including rent at fair market value). None of the
Shareholders, nor any relative or affiliate thereof, own any asset, tangible or
intangible, which is used in the business of the Company, other than real
property leased to the Company at fair market value, which leases are set forth
on Exhibit 3.1(h).

               (ii) The Company does not lease the Premises, but employees of
the Company occupy space in the premises of OC Mergerco 2, Inc. in Seattle,
Washington.

          (k)  Product Quality, Warranty and Liability. To the best knowledge of
the Company and the Shareholders, all services and products sold, leased,
provided or delivered by the Company to customers on or prior to the Closing
Date conform to applicable contractual commitments, express and implied
warranties, product and service specifications and quality standards, and there

accordance with good industry practice. All such insurance policies are valid,
in full force and effect and enforceable in accordance with their respective
terms and no party has repudiated any provision thereof. All such policies will
remain in full force and effect until the Closing Date. Neither the Company nor,
to the best knowledge of the Company and the Shareholders, any other party to
any such policy is in breach or default (including with respect to the payment
of premiums or the giving of notices) in the performance of any of their
respective obligations thereunder, and no event exists which, with the giving of
notice or the lapse of time or both, would constitute a breach, default or event
of default, or permit termination, modification or acceleration under any such
policy. There are no claims, actions, proceedings or suits arising out of or
based upon any of such policies nor, to the best knowledge of the Company and
the Shareholders, does any basis for any such claim, action, suit or proceeding
exist. All premiums have been paid on such policies as of the date of this
Agreement and will be paid on such policies through the Closing Date. The
Company has been covered since the inception of the Company by insurance in
scope and amount customary and reasonable for the businesses in which it has

failure of any pre-Closing or post-Closing distribution of benefits to employees

Requirements. Neither the Acquiror nor PentaStar will have any obligation to
employ any employee of the Company or to continue any Employee Benefit Plan, and

group health plan continuation coverage to which any employee, former employee
or dependent is entitled because of a qualifying event (as defined in Section
4980B(f)(3) of the Code) occurring through the Closing Date or as a result of
termination of employment with the Company because of the transactions
contemplated by this Agreement and any benefit or excise tax liability or
penalty or other costs arising from any failure by the Company to provide group
health plan continuation coverage. Except as set forth on Exhibit 3.1(m),
neither the Company nor any Affiliated Group which includes the Company (if any)
maintains, administers or contributes to, has maintained, administered or
contributed to, or has any Liability to contribute to, any Employee Benefit
Plan. Exhibit 3.1(m) lists each Employee Benefit Plan that is, or at any time
during the past six years was, maintained, administered, contributed to or
required to be contributed to by the Company or any Affiliated Group (if any)
which includes or has included the Company, and the date of termination of each
such Employee Benefit Plan (if any) which has been terminated. The Company has
no Liability (and there is no basis for the assertion of any Liability) as a
result of the Company's or any such Affiliated Group's maintenance,
administration or termination of, or contribution to, any Employee Benefit Plan.
Neither the Company nor any member of any Affiliated Group (if any) which
includes or has included the Company has ever been required to contribute to any
Multiemployer Plan (as defined in ERISA Section 3(37)) nor has incurred any
Liability under Title IV of ERISA.

          (n)  Employees and Labor. Except as set forth on Exhibit 3.1(n), the
Company has not received any notice, nor, to the best knowledge of the Company
and the Shareholders, is there any reason to believe that any executive or Key
Employee of the Company or any material group of employees of the Company has
any plans to terminate his, her or its employment with the Company. To the best
knowledge of the Company and the Shareholders, no executive or Key Employee is
subject to any agreement, obligation, Order or other legal hindrance that
impedes or might impede such executive or Key Employee from devoting his or her
full business time to the affairs of the Company prior to the Closing Date and,
if such person becomes an employee of the Acquiror or PentaStar, to the affairs
of the Acquiror or PentaStar after the Closing Date. The Company will not be
required to give any notice under the Worker Adjustment and Retraining
Notification Act, as amended (29 U.S.C.A. Section 2101, et. seq.), or any
similar Legal Requirement as a result of this Agreement, the Other Seller
Agreements or the transactions contemplated hereby or thereby. To the best
knowledge of the Company and the Shareholders, the Company does not have any
labor relations problems or disputes, nor has the Company experienced any
strikes, grievances, claims of unfair labor practices or other collective
bargaining disputes. The Company is not a party to or bound by any collective
bargaining agreement, there is no union or collective bargaining unit at the
Company's facilities, and, to the best knowledge of the Company and the
Shareholders, no union organization effort has been threatened, initiated or is
in progress with respect to any employees of the Company.

          (o)  Customer and Service Provider Relationships. Each customer that
individually or with its affiliates was, based on the Company's revenues during
the fiscal year ended December 31, 1998 or the eleven-month period ended
November 30, 1999, one of the Company's ten largest customers during such fiscal
year or period or accounted for 2% or more of the Company's revenues during such
fiscal year or period is referred to as a "Principal Customer." Each Person who
is a service provider to the Company as of the date of this Agreement is
referred to as a "Principal Provider." To the best knowledge of the Company and
the Shareholders, the Company has good commercial working relationships with its
Principal Customers and Principal Providers and since December 31, 1998, no
Principal Customer or Principal Provider has cancelled or otherwise terminated
its relationship with the Company, materially decreased its purchases from or
services supplied to the Company, or threatened to take any such action. The
Company and the Shareholders have no reasonable basis to anticipate any problems
with the Company's customer or service provider relationships. To the best
knowledge of the Company and the Shareholders, no Principal Customer or


                                      -10-
<PAGE>   15


Principal Provider has any plans to terminate their relationship with the
Company and the execution and delivery of this Agreement and the consummation of
the transactions contemplated hereby will not adversely affect the relationship
of the Company with any Principal Customer or Principal Provider prior to the
Closing Date or of the Acquiror or PentaStar with any Principal Customer or
Principal Provider after the Closing Date.

          (p)  Environmental Matters. To the best knowledge of the Company and
the Shareholders, the Company is conducting and at all times has conducted its
business and operations, and has occupied, used and operated the Premises and
all other real property and facilities presently or previously owned, occupied,
used or operated by the Company, in compliance with all Environmental
Obligations and so as not to give rise to Liability under any Environmental
Obligations or to any impact on the Company's business or activities. To the
best knowledge of the Company and the Shareholders, the Company has no Liability
under any Environmental Obligation, nor is there any basis for any such
Liability.

          (q)  Intellectual Property. To the best knowledge of the Company and
the Shareholders and with the proviso as to the Company name and tradename set
forth in Section 3.1(g)(i), the Company owns or has the legal right to use each
item of Intellectual Property required to be identified on Exhibit 3.1(h).
Except as provided on Exhibit 3.1(h) and with the proviso as to the Company name
and tradename set forth in Section 3.1(g)(i), to the best knowledge of the
Company and the Shareholders, the continued operation of the business of the
Company as currently conducted will not interfere with, infringe upon,
misappropriate or conflict with any Intellectual Property rights of another
Person. To the best knowledge of the Company and the Shareholders, no other
Person has interfered with, infringed upon, misappropriated or otherwise come
into conflict with any Intellectual Property rights of the Company or any
Intellectual Property included in the Acquired Assets. The Company has not
granted any license, sublicense or permission with respect to any Intellectual
Property owned or used in the Company's business. No claims are pending or, to
the knowledge of the Company and the Shareholders, threatened, that the Company
is infringing or otherwise adversely affecting the rights of any Person with
regard to any Intellectual Property. To the best knowledge of the Company and
the Shareholders and with the proviso as to the Company name and tradename set
forth in Section 3.1(g)(i), all of the Intellectual Property that is owned by
the Company is owned free and clear of all Encumbrances and was not
misappropriated from any Person, and all portions of the Intellectual Property

the consummation of the transactions contemplated by this Agreement will not
result in the loss or material diminution of any Intellectual Property or rights
in Intellectual Property.

          (r)  Year 2000 Warranty. To the best knowledge of the Company and the
Shareholders, the computer software owned by the Company and all other
Intellectual Property used or held for use by the Company in its business
accurately processes date/time data (including calculating, comparing, and
sequencing) from, into, and between the twentieth and twenty-first centuries,
and the years 1999 and 2000 and leap year calculations and the date September 9,
1999 when either (i) used as a standalone application, or (ii) integrated into
or otherwise used in conjunction with the third party hardware, software,
firmware and data over which the Shareholders and the Company have no control
("Third Party Products") with which such Company software or other Intellectual
Property was designated or intended to operate at the time such Company software
was (i) developed or (ii) first provided to the Company's customers, or tested
by the Company for such customers, whichever is later. Notwithstanding the
foregoing, the Company shall not be considered to be in breach of the
representation and warranty in the immediately preceding sentence if the failure
of such Company software to comply with such representation and warranty is
attributable solely to


                                      -11-
<PAGE>   16


(x) a failure by any Third Party Product to accurately process date/time data
(including but not limited to, calculating, comparing, and sequencing) from,
into, and between the twentieth and twenty-first centuries, and the years 1999
and 2000 and leap year calculations and the date September 9, 1999; or (y) any
modification of the Company software by any party other than the Company (unless
such modification was made at the direction of the Company).

          (s)  Brokers' Fees. Except as set forth on Exhibit 3.1(s), neither the
Company nor any Shareholder has, and will not have as a result of the
consummation of this Agreement, any Liability to pay any fees or commissions to
any broker, finder or agent with respect to the transactions contemplated by
this Agreement.

          (t)  Guaranties. The Company is not a guarantor or otherwise liable
for any Liability (including indebtedness for borrowed money) of any other
Person. Except as set forth on Exhibit 3.1(t), no Person is a guarantor or
otherwise liable for any Liability (including indebtedness for borrowed money)
of the Company.

          (u)  Disclosure. To the best knowledge of the Company and the
Shareholders, one of the documents or information provided to PentaStar by the
Company, any Shareholder or any agent or employee thereof in the course of
PentaStar's due diligence investigation and the negotiation of this Agreement
and Section 3.1 of this Agreement and the disclosure Exhibits referred to
therein, including the financial statements referred to above in Section 3.1,
contains any untrue statement of any material fact or omit to state a material
fact necessary in order to make the statements contained herein or therein not
misleading. To the best knowledge of the Company and the Shareholders, there is
no fact which materially adversely affects the business, condition, affairs or
operations of the Company or any of its properties or assets which has not been
set forth in this Agreement or such Exhibits, including such financial
statements.

          Nothing in the disclosure Exhibits referred to in Section 3.1 shall be
deemed adequate to disclose an exception to a representation or warranty made
herein unless the applicable disclosure Exhibit identifies the exception with
particularity and describes the relevant facts in reasonable detail. Without
limiting the generality of the foregoing, the mere listing (or inclusion of a
copy) of a document or other item shall not be deemed adequate to disclose an
exception to a representation or warranty made herein (unless the representation
or warranty has to do with the existence of the document or other item itself).
Each of the Company and the Shareholders acknowledge and agree that the fact
that they have made disclosures pursuant to Section 3.1 or otherwise of matters,
or did not have knowledge of matters, which result in Adverse Consequences to
PentaStar or the Acquiror shall not relieve the Company and the Shareholders of
their obligation pursuant to Section 7 of this Agreement to indemnify and hold
PentaStar and the Acquiror harmless from all Adverse Consequences, to the extent
provided in this Agreement.

     3.2. Representations and Warranties of PentaStar. PentaStar represents and
warrants to the Company and the Shareholders that the statements contained in
this Section 3.2 are correct and complete as of the date of this Agreement and
will be correct and complete as of the Closing Date (as though made then and as
though the Closing Date were substituted for the date of this Agreement
throughout this Section 3.2).

Acquiror are each corporations duly organized, validly existing and in good
standing under the laws of the State of Delaware. This Agreement and the Other
PentaStar Agreements and the transactions contemplated hereby and thereby have
been duly approved by all requisite corporate action. Each of PentaStar and the
Acquiror have full

the Other PentaStar Agreements to which it is a party, and this Agreement
constitutes, and the Other PentaStar Agreements will when executed and delivered
constitute, the legal, valid and binding obligations of PentaStar or the
Acquiror, as the case may be, and shall be enforceable in accordance with their
respective terms against PentaStar or the Acquiror, as the case may be.

          (b)  Capitalization. All of the issued and outstanding capital stock
of the Acquiror is owned by PentaStar.

          (c)  No Violation of Agreements, Etc. The execution, delivery and
performance of this Agreement and the Other PentaStar Agreements, and the
consummation of the transactions contemplated hereby and thereby will not (i)
violate any Legal Requirement to which PentaStar or the Acquiror is subject or
any provision of the certificate of incorporation or bylaws of PentaStar or the
Acquiror or (ii) violate, with or without the giving of notice or the lapse of
time or both, or conflict with or result in the breach or termination of any
provision of, or constitute a default under, or give any Person the right to

instrument or other arrangement to which PentaStar or the Acquiror is a party or
by which PentaStar or the Acquiror or any of their respective assets and
properties is bound or subject. Except for notices and consents that will be
given or obtained by PentaStar prior to the Closing, neither PentaStar nor the
Acquiror need to give any notice to, make any filing with or obtain any
authorization, consent or approval of any Governmental Authority or other Person
in order for the parties to consummate the transactions contemplated by this
Agreement.

     3.3. Survival of Representations. The representations and warranties
contained in Sections 3.1 and 3.2 and the Liabilities of the parties with
respect thereto shall survive any investigation thereof by the parties and shall
survive the Closing for 30 months, except that the Liabilities of the
Shareholders with respect to the representations and warranties set forth in
Sections 3.1(a), 3.1(b), 3.1(c), 3.1(f), 3.1(m) and 3.1(p) and the Liabilities
of PentaStar with respect to the representations and warranties set forth in
Sections 3.2(a) and 3.2(b), shall survive without termination.

     3.4. Representations as to Knowledge. The representations and warranties
contained in Article 3 hereof will in each and every case where an exercise of
discretion or a statement to the "best knowledge," "best of knowledge" or
"knowledge" is required on behalf of any party to this Agreement be deemed to
require that such exercise of discretion or statement be in good faith after
reasonable investigation (including, in the case of the Company and the
Shareholders, inquiry of the applicable employees of the Company), with due
diligence, to the best efforts of such party and be exercised always in a
reasonable manner and within reasonable times.

4.   Pre-Closing Covenants. The parties agree as follows with respect to the

business; provided, however, that in no event will any action be taken or fail
to be taken or any transaction be entered into which would result in a breach of
any representation, warranty or covenant of the Company or any Shareholder. The
Company will, and the Shareholders will cause the Company to, keep its business
and properties, including its current operations, physical facilities, working
conditions and relationships with customers, service providers, lessors,
licensors and employees, intact.

     4.3. Full Access. The Company will, and the Shareholders will cause the

     4.4. Notice of Developments. The Company and the Shareholders will give
prompt written notice to PentaStar of any material development which occurs
after the date of this Agreement and before the Closing and affects the
business, assets, Liabilities, financial condition, operations, results of

misrepresentation, breach of warranty or breach of covenant.

     4.5. Exclusivity. Neither the Company nor any Shareholder will, and the
Shareholders will not cause or permit the Company to, (a) solicit, initiate or

consolidation or share exchange) or (b) participate in any discussions or
negotiations regarding, furnish any information with respect to, assist or
participate in or facilitate in any other manner any effort or attempt by any
Person to do or seek any of the foregoing. No Shareholder will vote shares of
the Company's stock in favor of any such transaction. The Company and the
Shareholders will notify PentaStar immediately if any Person makes any proposal,
offer, inquiry or contact with respect to any of the foregoing.

     4.6. Announcements; Securities Law Restrictions. Prior to the Closing,
neither any Shareholder nor the Company shall disclose to any Person, nor issue
any press release or make any public announcement concerning, the existence,
terms or subject matter of this Agreement without the prior written approval of
PentaStar, except (and only to the extent) previously publicly announced by
PentaStar. Further, neither any Shareholder nor the Company shall violate the
United States securities laws which restrict each Shareholder and the Company,
as Persons with material non-public information concerning PentaStar obtained
directly or indirectly from PentaStar, from purchasing or selling securities of
PentaStar or from communicating such information to any other Person under any
circumstances in which it is reasonably foreseeable that such Person is likely
to purchase or sell such securities.

transfer law and any other similar law of any applicable jurisdiction in respect

period following the Closing.

     5.1. Further Assurances. In case at any time after the Closing any further
action is necessary or desirable to carry out the purposes of this Agreement,
each of the parties will take such further action (including the execution and
delivery of such further instruments and documents) as any other party
reasonably may request, all at the sole cost and expense of the requesting party
(unless the requesting party is entitled to indemnification therefor under
Section 7).

     5.2. Transition. No Shareholder will knowingly take any action at any time
that is designed or intended to have the effect of discouraging any customer,
supplier, lessor, licensor or other business associate of the Company from
establishing or continuing a business relationship with PentaStar after the

     5.3. Cooperation. In the event and for so long as any party actively is
contesting or defending against any action, suit, proceeding, hearing,
investigation, charge, complaint, claim or demand in connection with (a) any
transaction contemplated by this Agreement or (b) any fact, situation,
circumstance, status, condition, activity, practice, plan, occurrence, event,
incident, action, failure to act or transaction on or prior to the Closing Date
involving any of the Acquired Assets or the Company's business, each of the
other parties will cooperate with such party and its counsel in the contest or
defense, make available their personnel, and provide such testimony as shall be
reasonably necessary in connection with the contest or defense, all at the sole
cost and expense of the contesting or defending party (unless the contesting or
defending party is entitled to indemnification therefor under Section 7).

     5.4. Confidentiality. The Company and the Shareholders will treat and hold
as confidential all Confidential Information concerning PentaStar, the Company's
business or the Acquired Assets, refrain from using any such Confidential
Information and deliver promptly to PentaStar or destroy, at the request and
option of PentaStar, all of such Confidential Information in its or their
possession.

     5.5. Post-Closing Announcements. Following the Closing, no Shareholder will
issue any press release or make any public announcement relating to the subject
matter of this Agreement without the prior written approval of PentaStar.

     5.6. Financial Statements. The Company and the Shareholders will, upon
request of PentaStar, cooperate with PentaStar and render such assistance to
PentaStar and its accountants as may be required to produce such historical and
on-going financial statements and audits as PentaStar may request, all at the
sole cost and expense of PentaStar, but without additional consideration to the
Shareholders. The Shareholders acknowledge that PentaStar may be required by
applicable law to include audited financial statements with respect to the
business of the Company in reports filed with governmental agencies and that the
inability to audit the financial statements as of the Closing Date promptly
after the Closing could have a material adverse effect on PentaStar.

     5.7. Satisfaction of Liabilities.

          (a)  The Company and the Shareholders will pay and perform, as and
when due, all Liabilities (other than the Assumed Liabilities) relating to the
Company, the business of the Company and


                                      -15-
<PAGE>   20


the Acquired Assets, including without limitation, all Taxes attributable to the
transactions contemplated by this Agreement.

          (b)  The Company and the Shareholders, at their expense, promptly will
take or cause to be taken any action necessary to remedy any failure of the
Premises or the acquired business to comply at the Closing Date with any Legal
Requirement, upon receipt of notice from PentaStar at any time.

          (c)  The Acquiror will pay and perform, as and when due (except to the
extent the validity thereof or the Liability therefor is being contested by the
Acquiror), the Assumed Liabilities.

     5.8. Repurchase of Unpaid Receivables. The Company and the Shareholders
guarantee that the Closing Accounts Receivable in the amount set forth in the
footnote to the balance sheet attached as Exhibit 5.8 will be fully paid to the
Acquiror in accordance with their terms at their recorded amounts not later than
180 days from the Closing Date. Upon demand by PentaStar at any time after 180
days from the Closing Date, the Company and the Shareholders shall pay to the
Acquiror the full amount of any unpaid Closing Accounts Receivable which is the
subject of such demand; provided, however, that no Shareholder shall be required
to pay more than 150% of the Shareholder's Pro Rata Amount. Upon such payment to
PentaStar, the Closing Accounts Receivable which are so paid for by the
Shareholders shall, without further action of any party, become the property of
the Shareholders. From the Closing until 180 days after the Closing Date,
PentaStar (through the Acquiror) will apply its standard accounts receivable
collection procedures to the Closing Accounts Receivable; provided, however,
neither the Acquiror nor PentaStar will not be required to institute suit,
utilize third-party collection agencies or other agents or take other
extraordinary collection actions with respect to the Closing Accounts
Receivable; and, provided further, that any failure of any collection activities
of the Acquiror, PentaStar or any such collection agency or other agent will not
relieve the Shareholders from their guarantee of the Closing Accounts Receivable
as described in this Section 5.8. With respect to the foregoing, all collections
for Closing Accounts Receivable shall be applied to the invoice to which such
collection relates; provided that if such invoice cannot be reasonably
identified by the Acquiror, such collections will be applied on a "first in,
first out" or FIFO basis, with the specific exception that a payment made by a
customer will not be applied against the oldest outstanding invoice for such
customer if such invoice has been disputed by the customer.

     5.9. Termination of Obligations. Effective as of the Closing Date, but only
if the Closing occurs, (a) the Mutual Acknowledgement and Agreement, the
Commissions Agreement and the sublease described in the definition of "NCI
Liabilities" and (b) any instruments, contracts or agreements (other than this
Agreement) pursuant to which PentaStar or OC Mergerco 2, Inc. may have Liability
to the Company are terminated.

any Shareholder breaches any of the representations or warranties of the Company
or any Shareholder contained herein and PentaStar gives notice thereof to the
Shareholders' Agent within the Survival Period, or if the Company or any
Shareholder breaches any covenants of the Company or any Shareholder contained
herein or any representations, warranties or covenants of the Company or any
Shareholder contained in any Other Seller Agreement and PentaStar gives notice
thereof to the Shareholders' Agent, then, subject to Section 7.6, the Company
and each Shareholder agree to indemnify and hold harmless PentaStar and the
Acquiror from and against any Adverse Consequences PentaStar or the Acquiror may
suffer resulting from, arising out of, relating to or caused by any of the
foregoing regardless of whether the Adverse Consequences are suffered during or
after the Survival Period, up to, but in no event to exceed, 150% of the sum of
all Shareholder's Pro Rata Amounts. In determining for all purposes under this
Agreement (including this Section 7 and Section 8) whether there has been a
breach of any representation or warranty contained in Section 3.1 and in
determining for purposes of the preceding sentence the amount of Adverse
Consequences suffered by PentaStar or the Acquiror, such representations and
warranties shall not be qualified (other than by (A) the reference to
"knowledge" set forth in the last sentence of Section 3.1(o) and (B) the
references to "material" set forth in Section 3.1(u)) by "material,"
"materiality," "in all material respects," "best knowledge," "best of knowledge"
or "knowledge" or words of similar import, or by any phrase using any such terms
or words. Each Majority Shareholder also agrees to indemnify and hold harmless
PentaStar and the Acquiror from and against any Adverse Consequences PentaStar
or the Acquiror may suffer, up to, but in no event to exceed, 150% of the
Shareholder's Pro Rata Amount of such Majority Shareholder, and each Minority
Shareholder agrees to indemnify and hold harmless PentaStar and the Acquiror
from and against any Adverse Consequences PentaStar or the Acquiror may suffer,
but in no event to exceed 100% of the Shareholder's Pro


                                      -18-
<PAGE>   23


Rata Amount of such Minority Shareholder, which result from, arise out of,
relate to or are caused by (i) any Liability of the Company or any Shareholder
not included in the Assumed Liabilities or (ii) any condition, circumstance or
activity existing prior to the Closing Date which relates to any Legal
Requirement or any act or omission of the Company or any Shareholder or any
predecessor with respect to, or any event or circumstance related to, the
Company's, any Shareholder's or any predecessor's ownership, use or operation of
any of the Acquired Assets, the Premises or any other assets or properties or
the conduct of its or their business, regardless, in the case of (i) or (ii), of
(A) whether or not such Liability, act, omission, event, circumstance or matter
was known or disclosed to PentaStar, was disclosed on any Exhibit hereto or is a
matter with respect to which the Company or any Shareholder did or did not have
knowledge, (B) when such Liability, act, omission, event, circumstance or matter
occurred, existed, occurs or exists and (C) whether a claim with respect thereto
was asserted before or is asserted after the Closing Date and (iii) any
Liability resulting from any failure of the parties to comply with any
applicable bulk sales or transfer Legal Requirement in connection with the
transactions contemplated by this Agreement. If any dispute arises concerning
whether any indemnification is owing which cannot be resolved by negotiation
among the parties within 30 days of notice of claim for indemnification from the
party claiming indemnification to the party against whom such claim is asserted,
the dispute will be resolved by arbitration pursuant to this Agreement.
Notwithstanding the foregoing, the Liability of the Shareholders to indemnify
PentaStar and the Acquiror in the aggregate under this Section 7.1 shall not
exceed the sum of all Shareholder's Pro Rata Amounts. The date of any notice of
any claim for indemnification given by PentaStar to the Shareholders' Agent
shall be referred to as a "Notice Date."

     7.2. Indemnification Provisions for Benefit of the Company and the
Shareholders. If PentaStar breaches (or if any Person other than the Company or
a Shareholder alleges facts that, if true, would mean PentaStar has breached)
any of its representations or warranties contained herein and the Shareholders'
Agent gives notice of a claim for indemnification against PentaStar within the
Survival Period, or if PentaStar breaches any of its covenants contained herein
or any of its representations, warranties or covenants contained in any Other
PentaStar Agreement and the Shareholders' Agent gives notice thereof to
PentaStar, then PentaStar agrees to indemnify and hold harmless the Company and
the Shareholders from and against any Adverse Consequences the Company and the
Shareholders may suffer which result from, arise out of, relate to, or are
caused by the breach or alleged breach, regardless of whether the Adverse
Consequences are suffered during or after the Survival Period. In determining
whether there has been a breach of any representation or warranty contained in
Section 3.3 and in determining the amount of Adverse Consequences suffered by
the Company and the Shareholders for purposes of this Section 7.2, such
representations and warranties shall not be qualified by "material,"
"materiality," "in all material respects," "best knowledge," "best of knowledge"
or "knowledge" or words of similar import, or by any phrase using any such terms
or words. If any dispute arises concerning whether any indemnification is owing
which cannot be resolved by negotiation among the parties within 30 days of
notice of claim for indemnification from the party claiming indemnification to
the party against whom such claim is asserted, the dispute will be resolved by
arbitration pursuant to this Agreement.

     7.3. Matters Involving Third Parties.

          (a)  If any Person not a party to this Agreement (including, without
limitation, any Governmental Authority) notifies any party (the "Indemnified
Party") with respect to any matter (a "Third Party Claim") which may give rise
to a claim for indemnification against any other party (the "Indemnifying
Party"), then the Indemnified Party will notify each Indemnifying Party thereof
in writing within 15 days after receiving such notice. No delay on the part of
the Indemnified Party in notifying any Indemnifying Party will


                                      -19-
<PAGE>   24


relieve the Indemnifying Party from any obligation hereunder unless (and then
solely to the extent) the Indemnifying Party thereby is prejudiced.

          (b)  Any Indemnifying Party will have the right, at its sole cost and
expense, to defend the Indemnified Party against the Third Party Claim with
counsel of its choice satisfactory to the Indemnified Party so long as (i) the
Indemnifying Party notifies the Indemnified Party in writing within 10 days
after the Indemnified Party has given notice of the Third Party Claim that the
Indemnifying Party will indemnify the Indemnified Party from and against the
entirety of any Adverse Consequences the Indemnified Party may suffer resulting
from, arising out of, relating to or caused by the Third Party Claim, (ii) the
Indemnifying Party provides the Indemnified Party with evidence reasonably
acceptable to the Indemnified Party that the Indemnifying Party will have the
financial resources to defend against the Third Party Claim and fulfill its
indemnification obligations hereunder, (iii) the Third Party Claim involves only
money damages and does not seek an injunction or other equitable relief, (iv)
settlement of, or an adverse judgment with respect to, the Third Party Claim is
not, in the good faith judgment of the Indemnified Party, likely to establish a
precedential custom or practice materially adverse to the continuing business
interests of the Indemnified Party, and (v) the Indemnifying Party conducts the
defense of the Third Party Claim actively and diligently. If the Indemnifying
Party does not assume control of the defense or settlement of any Third Party
Claim in the manner described above, it will be bound by the results obtained by
the Indemnified Party with respect to the Third Party Claim.

          (c)  So long as the Indemnifying Party is conducting the defense of
the Third Party Claim in accordance with Section 7.3(b) above, (i) the
Indemnified Party may retain separate co-counsel at its sole cost and expense
and participate in the defense of the Third Party Claim, (ii) the Indemnified
Party will not consent to the entry of any judgment or enter into any settlement
with respect to the Third Party Claim without the prior written consent of the
Indemnifying Party (not to be withheld unreasonably), and (iii) the Indemnifying
Party will not consent to the entry of any judgment or enter into any settlement
with respect to the Third Party Claim without the prior written consent of the
Indemnified Party (not to be withheld unreasonably).

          (d)  In the event any of the conditions in Section 7.3(b) above is or
becomes unsatisfied, however, (i) the Indemnified Party may defend against, and
consent to the entry of any judgment or enter into any settlement with respect
to, the Third Party Claim in any manner it reasonably may deem appropriate (and
the Indemnified Party need not consult with, or obtain any consent from, any
Indemnifying Party in connection therewith), (ii) the Indemnifying Parties will
reimburse the Indemnified Party promptly and periodically for the costs of
defending against the Third Party Claim (including reasonable attorneys' fees
and expenses), and (iii) the Indemnifying Parties will remain responsible for
any Adverse Consequences the Indemnified Party may suffer resulting from,
arising out of, relating to or caused by the Third Party Claim to the fullest
extent provided in this Section 7.

     7.4. Other Remedies. The foregoing indemnification provisions are in
addition to, and not in derogation of, any statutory, equitable or common law
remedy any party may have.

     7.5. Basket. Notwithstanding anything to the contrary in this Section 7,
the Company and the Shareholders will not have any obligation to indemnify
PentaStar or the Acquiror from and against any Adverse Consequences resulting
from, arising out of, relating to, in the nature of, or caused by the breach of
any representation or warranty of the Company or the Shareholders set forth in
Section 3.1 until PentaStar and the Acquiror have suffered Adverse Consequences
by reason of any or of all such breaches in excess of


                                      -20-

Ten Thousand Dollars ($10,000) in the aggregate, after which point the Company
and the Shareholders will be obligated to indemnify PentaStar and the Acquiror
from and against the entirety of any such Adverse Consequences exceeding Ten
Thousand Dollars ($10,000).

to the Shareholders' Agent at any time prior to the Closing (i) in the event the
Company or any Shareholder has breached any representation, warranty or covenant
contained in this Agreement in any material way, PentaStar has notified the
Shareholders' Agent of the breach, and the breach has not been cured within 10
days after the notice of breach or (ii) if the Closing has not occurred on or
before January 15, 2000 because of the failure of any condition precedent to
PentaStar's obligations to consummate the Closing (unless the failure results
primarily from PentaStar breaching any representation, warranty or covenant
contained in this Agreement in any material way); or

          (c)  the Shareholders' Agent may terminate this Agreement by giving
written notice to PentaStar at any time prior to the Closing (i) if PentaStar

because of the failure of any condition precedent to the Company's and the
Shareholders' obligations to consummate the Closing (unless the failure results
primarily from the Company or any Shareholder breaching any representation,
warranty or covenant contained in this Agreement in any material way).

     8.2. Effect of Termination. Neither the Company and the Shareholders, on
the one hand, nor PentaStar and the Acquiror, on the other hand, will have any
liability or obligation to the other upon termination of this Agreement for any
reason whatsoever, unless the termination is directly based on or arising from a
material breach of any representations, warranties or covenants contained in
this Agreement of the Company and the Shareholders, on the one hand, or
PentaStar and the Acquiror, on the other hand, and such breach results in,
relates to or concerns an item, fact or circumstance that is materially adverse
to the Company, on the one hand, or PentaStar or the Acquiror, on the other
hand, as applicable. In the case of such a breach, the Company and the
Shareholders, on the one hand, or PentaStar and the Acquiror, on the other hand,
shall be entitled to seek all relief to which it or they are entitled under
applicable law from PentaStar and the Acquiror, on the one hand, and the
Company, on the other hand, as applicable, but not from any Shareholder.
Notwithstanding anything herein in this Agreement to the contrary, no
Shareholders shall have any liability to PentaStar or the Acquiror upon the
termination of this Agreement for any reason whatsoever.

     8.3. Confidentiality. If this Agreement is terminated, each party will
treat and hold as confidential all Confidential Information concerning the other
parties which it acquired from such other parties in connection with this
Agreement and the transactions contemplated hereby.

federal and state arbitration statutes, and shall not be the subject of

Colorado selected by PentaStar and the Shareholders' Agent or, if they cannot

                                      -23-
<PAGE>   28


Arbitration Association. EACH PARTY, BY SIGNING THIS AGREEMENT, VOLUNTARILY,
KNOWINGLY AND INTELLIGENTLY WAIVES ANY RIGHTS SUCH PARTY MAY OTHERWISE HAVE TO
SEEK REMEDIES IN COURT OR OTHER FORUMS, INCLUDING THE RIGHT TO JURY TRIAL. The
arbitrator shall have full authority to order specific performance and other
equitable relief and award damages and other relief available under this
Agreement or applicable law, but shall have no authority to add to, detract
from, change or amend the terms of this Agreement or existing law. All
arbitration proceedings, including settlements and awards, shall be
confidential. The decision of the arbitrators will be final and binding, and
judgment on the award by the arbitrators may be entered in any court of
competent jurisdiction. THIS SUBMISSION AND AGREEMENT TO ARBITRATE WILL BE
SPECIFICALLY ENFORCEABLE. The prevailing party or parties in any such
arbitration or in any action to enforce this Agreement will be entitled to
recover, in addition to any other relief awarded by the arbitrator, all
reasonable costs and expenses, including fees and expenses of the arbitrators
and attorneys, incurred in connection therewith. If each party prevails on
specific issues in the arbitration, the arbitrator may allocate the costs
incurred by all parties on a basis the arbitrator deems appropriate.

     9.12. Construction. The parties have participated jointly in the
negotiation and drafting of this Agreement. In the event an ambiguity or
question of intent or interpretation arises, this Agreement will be construed as
if drafted jointly by the parties and no presumption or burden of proof will
arise favoring or disfavoring any party by virtue of the authorship of any of
the provisions of this Agreement. The word "including" will mean including
without limitation. The parties intend that each representation, warranty and
covenant contained herein will have independent significance. If any party
breaches any representation, warranty or covenant contained herein in any
respect, the fact that there exists another representation, warranty or covenant
relating to the same subject matter (regardless of the relative levels of
specificity) which the party has not breached will not detract from or mitigate
the fact that the party is in breach of the first representation, warranty or
covenant.

     9.13. Incorporation of Exhibits. The Exhibits identified in this Agreement
are incorporated herein by reference and made a part hereof.

     9.14. Shareholders' Agent. The Company and each Shareholder hereby
authorize and appoint the Shareholders' Agent as its, his or her exclusive agent
and attorney-in-fact to act on behalf of each of them with respect to all
matters which are the subject of this Agreement, including, without limitation,
(a) receiving or giving all notices, instructions, other communications,
consents or agreements that may be necessary, required or given hereunder and
(b) asserting, settling, compromising, or defending, or determining not to
assert, settle, compromise or defend, (i) any claims which the Company or any
Shareholder may assert, or have the right to assert, against PentaStar, or (ii)
any claims which PentaStar or the Acquiror may assert, or have the right to
assert, against the Company or any Shareholder. The Shareholders' Agent hereby
accepts such authorization and appointment. Upon the receipt of written evidence
satisfactory to PentaStar to the effect that the Shareholders' Agent has been
substituted as agent of the Company and the Shareholders by reason of his death,
disability or resignation, PentaStar shall be entitled to rely on such
substituted agent to the same extent as they were theretofore entitled to rely
upon the Shareholders' Agent with respect to the matters covered by this Section
9.14. Neither the Company nor any Shareholder shall act with respect to any of
the matters which are the subject of this Agreement except through the
Shareholders' Agent. The Company and the Shareholders acknowledge and agree that
PentaStar may deal exclusively with the Shareholders' Agent in respect of such
matters, that the enforceability of this Section 9.14 is material to PentaStar,
and that PentaStar has relied upon the enforceability of this Section 9.14 in
entering into this Agreement.

     2.3. Purchase Price; Payment.

         (a) The consideration payable by the Acquiror to the Company for the
Acquired Assets will consist of (i) cash in an amount of $2,100,000; (ii) such
number of PentaStar Shares (rounded to the nearest whole share) as have an
aggregate Fair Market Value as of the date of this Agreement of $950,000 (such
number of shares being referred to as the "Closing Shares"); (iii) the
assumption of the Assumed Liabilities; and (iv) the Earn-Out Amount payable
pursuant to Section 2.3(b) (collectively the "Purchase Price"). At the Closing,
the Acquiror will (i) pay to the Company by wire transfer to an account
designated by the Company $1,600,000 of the cash portion of the Purchase Price,
(ii) deposit the remaining $500,000 of the cash portion of the Purchase Price
(such $500,000 is referred to as the "Accounts Receivable Escrow Fund") and the
stock certificates representing the Closing Shares into the Escrow Account with
the Escrow Agent (which Closing Shares shall be issued by PentaStar in the name
of the Company and contributed by PentaStar to the Acquiror immediately prior to
the Closing) and (iii) assume the Assumed Liabilities. The Accounts Receivable
Escrow Fund, the Closing Shares and the other property held in the Escrow
Account shall be held and disbursed according to this Agreement and the Escrow
Agreement.

         (b) In addition to the cash portion of the Purchase Price and the
Closing Shares payable and issuable at the Closing pursuant to Section 2.3(a),
the Company shall be entitled to receive the Earn-Out Amount determined and
payable as provided in this Section 2.3(b).

             (i) PentaStar agrees that, during the Earn-Out Period, the Acquiror
will conduct the operations represented by the Acquired Assets in the ETI Region
as a separate subsidiary of PentaStar with no other operations. PentaStar agrees
that, during the Earn-Out Period, it will not allocate any corporate expense or
otherwise cause the ETI Region to incur any corporate or other expense not
specifically related to the business of the ETI Region.

             (ii) As soon as reasonably practicable after the end of the
Earn-Out Period, and in any event by March 31, 2001, PentaStar will cause the
independent auditors who audit its financial statements for the year 2000 to
prepare an audited income statement of the Acquiror for the Earn-Out Period and
a written calculation of the Earn-Out Amount (collectively, the "Earn-Out
Financial Statements"). PentaStar will promptly provide a copy of the Earn-Out
Financial Statements to the Company. Within 20 days after receipt of the
Earn-Out Financial Statements, each of PentaStar and the Company will, in a
written notice to the other, either accept the Earn-Out Financial Statements or
object to them by describing in reasonably specific detail any proposed
adjustments to the Earn-Out Financial Statements and the estimated amounts of
and reasons for such proposed adjustments. The failure by PentaStar or the
Company to object to the Earn-Out Financial Statements within such 20-day period
will be deemed to be an acceptance by such Person of the Earn-Out Financial
Statements. If any adjustments to the Earn-Out Financial Statements are proposed
by PentaStar or the Company within such 20-day period, the dispute shall be
resolved as provided in Section 2.3(b)(v). The reasonable fees and expenses of
the independent auditors for the preparation of the Earn-Out Financial
Statements, other than those associated with the normal year-end audit of
PentaStar or the Acquiror, shall be paid 50% by PentaStar and 50% by the
Company.

             (iii) Within 10 Business Days after the later of the acceptance of
the Earn-Out Financial Statements by PentaStar and the Company or the resolution
of any disputes under Section 2.3(b)(v), as the case may be, the Acquiror shall
pay the Earn-Out Amount, if any, to the Company. The Earn-Out Amount shall be
paid, in PentaStar's sole discretion, in cash or PentaStar Common Stock, or any
combination thereof. If any portion of the Earn-Out Amount is paid in PentaStar
Common Stock, the number of shares

                                       -2-

<PAGE>   7



of PentaStar Common Stock to be issued (which shall be rounded to the nearest
whole share) will be determined by dividing (A) the Earn-Out Amount that is
being paid in PentaStar Common Stock by (B) a per share value of PentaStar
Common Stock that is equal to 90% of the Fair Market Value as of the date such
Earn-Out Amount is paid, and such shares shall be issued by PentaStar in the
name of the Company or Brian S. Rowley, as the case may be, in the amounts
determined as set forth below, and contributed by PentaStar to the Acquiror
immediately prior to the delivery of such shares by the Acquiror. If any shares
of PentaStar Common Stock are issued in the name of the Company pursuant to this
Section 2.3(b)(iii), the Acquiror shall deposit the stock certificates
representing such shares into the Escrow Account with the Escrow Agent. If the
Earn-Out Amount becomes payable by the Acquiror, the Company shall pay to Mr.
Rowley (however delivery may be delayed if such shares are in escrow) the amount
determined pursuant to Exhibit 2.3(b)(iii) (and if the Earn-Out Amount is
comprised of a combination of cash and PentaStar Common Stock, then Mr. Rowley
shall receive cash and PentaStar Common Stock from the Company in the same
proportions as the cash and PentaStar Common Stock comprising the Earn-Out
Amount (the shares of PentaStar Common Stock, if any, issued in the name of Mr.
Rowley are referred to as the "Rowley Shares")). The cash portion of the
Earn-Out Amount shall be paid by wire transfer to an account designated by the
Company.

             (iv) In the event that PentaStar sells the operations conducted by
the Acquiror prior to the end of the Earn-Out Period, PentaStar shall require
the purchaser to continue to account for such operations separately and agree to
assume the obligation of the Acquiror to pay the Earn-Out Amount as provided in
this Section 2.3(b), including the obligation to comply with the provisions of
Section 2.3(b)(i).

             (v) If any adjustments to the Earn-Out Financial Statements are
proposed by PentaStar or the Company pursuant to Section 2.3(b)(ii), PentaStar
and the Company will negotiate in good faith to resolve any dispute, provided
that if the dispute is not resolved within 10 days following the receipt of the
proposed adjustments then PentaStar and the Company will retain the Boston,
Massachusetts office of (or office most geographically proximate to Boston,
Massachusetts) BDO Seidman LLC to resolve such dispute, which resolution will be
final and binding. The fees and expenses of BDO Seidman LLC will be paid 50% by
PentaStar and 50% by the Company, and BDO Seidman LLC will be retained under a
retention letter executed by the parties that specifies that the determination
by said firm of any such disputes will be resolved in accordance with this
Agreement (including the definitions of "Earn-Out Amount," "Earn-Out Period,"
"Earn-Out Period EBITA" and "EBITA" set forth in this Agreement), by choosing

intangible assets which are included in the Acquired Assets. The parties
acknowledge that such allocations for Tax reporting purposes were determined

in a jurisdiction where the Company, UST or VNS does not file Tax Returns that
it is or may be subject to taxation by that jurisdiction. There are no

that arose in connection with any failure (or alleged failure) to pay any Tax.

Encumbrances (other than the Permitted Encumbrances in the event that, subject

Corporation as of the Closing). Neither the Company, UST nor VNS has entered
into any contract or made any commitment to sell all or any part of its assets,

or commitment to sell assets. The Company Acquired Assets constitute all of the
real, personal and mixed assets and property, both tangible and intangible,
including Intellectual Property, which are being used or held for use by the
Company in the conduct of the business and operations of the Company, consistent
with historical and current practices. The UST/VNS Assets constitute all of the
real, personal and mixed assets and property, both tangible and intangible,
including Intellectual Property, which are being used or held for use by UST or
VNS in the conduct of their respective business and operations, consistent with
historical and current practices. Each of the Company, UST and VNS owns or

business as presently conducted and as presently proposed to be conducted. Each
such tangible asset material to the Company's, UST's or VNS's operations is in
good operating condition and repair. There are no leases of real property
between the Company, UST or VNS and any shareholder, officer or director or any

tangible or intangible, which is used in the business of the Company, UST or
VNS, as the case may be, other than assets which will be included in the

of any Legal Requirement or Permit relating to its operations or its owned or
leased properties.

             (iii) No party to any lease with respect to any Premises has

remain in full force and effect until the Closing. Neither the Company nor any
other party to any such policy is in breach or default (including with respect
to the payment of premiums or the giving of notices) in the performance of any
of their respective obligations thereunder, and no event exists which, with the
giving of notice or the lapse of time or both, would constitute a breach,
default or event of default, or permit termination, modification or acceleration
under any such policy. There are no claims, actions, proceedings or suits
arising out of or based upon any of such policies nor, to the best knowledge of
the Company and the Shareholder, does any basis for any such claim, action, suit
or proceeding exist. All premiums have been paid on such policies as of the date
of this Agreement and will be paid on such policies through the Closing. Each of
the Company, UST and VNS has been covered during the three years prior to the

and any benefit or excise tax liability or penalty or other costs arising from

basis for the assertion of any Liability) as a result of the Company's, UST's or

of, or contribution to, any Employee Benefit Plan. Neither the Company nor any
member of any Affiliated Group (if any) which includes or has included the

believe that any Key Employee of the Company, UST or VNS or any group of
employees of the Company, UST or VNS has made plans to terminate his, her or its
employment with the Company, UST or VNS, as the case may be. To the best
knowledge of the Company and the Shareholder, no Key Employee is subject to any
agreement, obligation, Order or other legal hindrance that impedes or might
impede such Key Employee from devoting his or her full business time to the
affairs of the Company, UST or VNS, as the case may be, prior to the Closing
and, if such person becomes an employee of the Acquiror or PentaStar, to the
affairs of the Acquiror or PentaStar after the Closing. None of the Company, UST
or VNS will be required to give any notice under the Worker Adjustment and

bound by any collective bargaining agreement, there is no union or collective
bargaining unit at the Company's, UST's or VNS's facilities, and no union
organization effort has been threatened, initiated or is in progress with
respect to any employees of the Company, UST or VNS.

         (o) Customer and Service Provider Relationships. The customers listed
on Exhibit 3.1(o)(i) (the "Large Customers"), individually or with their
respective affiliates, accounted for the respective revenues of the Company, UST
and VNS during the fiscal year ended December 31, 1998 or the fiscal year ended
December 31, 1999, the revenues of the Company, UST or VNS set forth opposite

ledgers. Exhibit 3.1(o)(ii) lists each Person who was a service provider to the
customers of the Company, UST or VNS as of December 31, 1999 or as of the date

1999 no Large Customer (except as set forth on Exhibit 3.1(o)(iii)) or Principal
Provider has canceled or otherwise terminated its relationship with the Company,
UST or VNS, as the case may be, materially decreased its services supplied to
the Company, UST or VNS, as the case may be, or threatened to take any such
action. The Company and the Shareholder have no basis to anticipate any problems
with the Company's, UST's or VNS's customer or service provider relationships.
To the best knowledge of the Company and the Shareholder (and the Company and
the Shareholder have no obligation in making this representation to make inquiry
of any Large Customer or Principal Provider as to such Large Customer's or
Principal Provider's plans), no Large Customer (except as set forth on Exhibit
3.1(o)(iii)) or Principal Provider has any plans to terminate its relationship
with the Company, UST or VNS and the execution and delivery of this Agreement
and of the UST/VNS Acquisition Agreement and the consummation of the
transactions contemplated hereby and thereby will not adversely affect the
relationship of the Company, UST or VNS with any Large Customer or Principal
Provider prior to the Closing (or in the case of the UST/VNS Acquisition

Customer or Principal Provider after the Closing (or in the case of the UST/VNS
Acquisition Agreement, the closing thereunder).

conducting and at all times has conducted its business and operations, and has
occupied, used and operated its Premises and all other real property and
facilities presently or previously owned, occupied, used or operated by it, in

Liability under any Environmental Obligations or to any impact on the Company's,
UST's or VNS's business or activities. None of the Company, UST or VNS has any
Liability under any Environmental Obligation, nor is there any basis for any
such Liability.

         (q) Intellectual Property. The Company owns or has, or will upon the
closing under the UST/VNS Acquisition Agreement own or have, the legal right to
use each item of Intellectual Property required to be identified on Exhibit

The continued operation of the business of the Company, UST or VNS as currently
conducted will not interfere with, infringe upon, misappropriate or conflict
with any Intellectual Property rights of another Person. To the best knowledge
of the Company and the Shareholder, no other Person has interfered with,
infringed upon, misappropriated or otherwise come into conflict with any
Intellectual Property rights of the Company, UST or VNS or any Intellectual
Property included in the Acquired Assets. Neither the Company, UST or VNS nor
any owner of any Intellectual Property included in the Acquired Assets has
granted any license, sublicense or permission with respect to any Intellectual
Property owned or used in the Company's, UST's or VNS's business. No claims are
pending or, to the knowledge of the Company and the Shareholder, threatened,
that the Company, UST or VNS is infringing or otherwise adversely affecting the
rights of any

                                      -13-

<PAGE>   18



Person with regard to any Intellectual Property. To the best knowledge of the

the Company, UST or VNS is owned free and clear of all Encumbrances and was not
misappropriated from any Person, and all portions of the Intellectual Property

Shareholder, the computer software owned by the Company, UST or VNS and all
other Intellectual Property used or held for use by the Company, UST or VNS in
its business accurately processes date/time data (including calculating,
comparing, and sequencing) from, into, and between the twentieth and
twenty-first centuries, and the years 1999 and 2000 and leap year calculations
and the date September 9, 1999 when either (i) used as a standalone application,
or (ii) integrated into or otherwise used in conjunction with the third party
hardware, software, firmware and data over which the Shareholder, the Company,

or VNS software or other Intellectual Property was designated or intended to
operate at the time such Company, UST or VNS software was (A) developed or (B)
first provided to the Company's, UST's or VNS's customers, or tested by the
Company, UST or VNS for such customers, whichever is later. Notwithstanding the
foregoing, the Company, UST or VNS shall not be considered to be in breach of
the representation and warranty in the immediately preceding sentence if the
failure of such Company, UST or VNS software to comply with such representation
and warranty is attributable solely to (x) a failure by any Third Party Product
to accurately process date/time data (including but not limited to, calculating,
comparing, and sequencing) from, into, and between the twentieth and
twenty-first centuries, and the years 1999 and 2000 and leap year calculations
and the date September 9, 1999; or (y) any modification of the Company, UST or
VNS software by any party other than the Company, UST or VNS (unless such

set forth in clause (i) of the first sentence of this Section 3.1(r); provided,
however, that such computers have been networked together to allow the Company
to operate the telecenter business in a manner consistent with past practice
without loss of material data.

     4.3. Full Access. The Company will, and the Shareholder will cause the
Company to, permit PentaStar and its agents to have full access at all
reasonable times, and in a manner so as not to interfere with the normal
business operations of the Company, to all premises, properties, personnel,
books, records (including Tax records), contracts and documents of or pertaining
to the Company, UST or VNS.

     4.4. Notice of Developments. The Company and the Shareholder will give
prompt written notice to PentaStar of any material development which occurs
after the date of this Agreement and before the Closing and affects the
business, assets, Liabilities, financial condition, operations, results of
operations, future prospects, representations, warranties, covenants or
disclosure Exhibits of the Company, UST or VNS. No such written notice, however,
will be deemed to amend or supplement any disclosure Exhibit or to prevent or
cure any misrepresentation, breach of warranty or breach of covenant.

     4.5. Exclusivity. Neither the Company nor the Shareholder will, and the
Shareholder will not cause or permit the Company to, (a) solicit, initiate or
encourage the submission of any proposal or offer from any Person relating to

of the assets of, the Company (including any acquisition structured as a merger,
consolidation or share exchange) or (b) participate in any discussions or
negotiations regarding, furnish any information with respect to, assist or
participate in or facilitate in any other manner any effort or attempt by any
Person to do or seek any of the foregoing. The Shareholder will not vote shares
of the Company's stock in favor of any such transaction. The Company and the
Shareholder will notify PentaStar immediately if any Person makes any proposal,
offer, inquiry or contact with respect to any of the foregoing.

     4.6. Announcements; Securities Law Restrictions. Prior to the Closing,
neither the Shareholder nor the Company shall disclose to any Person, nor issue
any press release or make any public announcement concerning, the existence,
terms or subject matter of this Agreement without the prior written approval of
PentaStar, except (and only to the extent) previously publicly announced by
PentaStar and the Shareholder shall coordinate its initial release with respect
to this Agreement with PentaStar. Further, neither the

                                      -18-

<PAGE>   23



Shareholder nor the Company shall violate the United States securities laws
which restrict the Shareholder and the Company, as Persons with material
non-public information concerning PentaStar obtained directly or indirectly from
PentaStar, from purchasing or selling securities of PentaStar or from
communicating such information to any other Person under any circumstances in
which it is reasonably foreseeable that such Person is likely to purchase or
sell such securities.

     4.7. Bulk Sales Laws. In reliance upon its indemnification rights set forth
in Section 7, the Acquiror waives compliance by the Company with the bulk
transfer law and any other similar law of any applicable jurisdiction in respect
to the transactions contemplated by this Agreement.

     4.8 Shareholders' Meeting.

         (a) The Shareholder, acting through its board of directors, shall, in
accordance with applicable Legal Requirements and the Shareholder's articles or
certificate of incorporation and bylaws, duly call, give notice of, convene and
hold a meeting (including any adjournment or postponement thereof, the
"Meeting") of its shareholders as soon as practicable following the date of this
Agreement, but in any event no later than 20 days after the mailing of the Proxy
Statement for the purpose of considering and taking action upon the approval of
the sale of the Acquired Assets to the Acquiror pursuant to this Agreement (the
"Transaction"). The Shareholder shall cause the Meeting to be held, and such
vote shall be taken not, later than May 31, 2000. The board of directors shall
recommend such approval by the shareholders and shall take all reasonable,
lawful action to solicit such approval by the shareholders of the Shareholder.

         (b) The Shareholder shall (i) as promptly as practicable following the
date of this Agreement, prepare and file with the SEC and use its best efforts
to have cleared by the SEC and thereafter mail to its shareholders as promptly
as practicable, a proxy statement and a form of proxy in connection with the
vote at the Meeting of its shareholders with respect to the Transaction (such
proxy statement, together with any amendments thereof or supplements thereto, in
each case in the form or forms mailed to the shareholders, is the "Proxy
Statement") and (ii) otherwise comply with all Legal Requirements applicable to
the Meeting. PentaStar shall be permitted to review drafts of such Proxy
Statement. The Shareholder will include in the Proxy Statement the
recommendation of its board of directors that shareholders of the Shareholder
vote in favor of the approval of the Transaction. The Shareholder shall notify
PentaStar promptly of the receipt of any comments of the SEC or its staff and of
any request by the SEC or its staff or any other governmental officials for
amendments or supplements to the Proxy Statement or for additional information,
and will supply PentaStar with copies of all correspondence between the
Shareholder and any of its representatives, on the one hand, and the SEC or its
staff or any other governmental officials, on the other hand, with respect to
the Proxy Statement. The Proxy Statement shall comply with all applicable Legal
Requirements.

         (c) The Shareholder shall cause each of its affiliates to vote at the
Meeting all shares of the capital stock of the Shareholder that each owns in
favor of the Transaction.

     4.9 Specified Consents. As of the date of this Agreement, the Company have
delivered to the Acquiror the third-party consents set forth on Exhibit 4.9(a)
which are satisfactory to the Acquiror. As of the date of this Agreement, all
other third-party consents delivered to the Acquiror are not satisfactory to the
Acquiror. Prior to the date the Required Vote is obtained, the Company and the
Shareholder shall obtain and deliver to the Acquiror the material third-party
consents set forth on Exhibit 4.9(b), any additional material third-party
consents required under agreements entered into by the Company after the date
hereof (the

                                      -19-

<PAGE>   24



"Specified Consents"). The documents described in Section 6.1(l) shall be for
the benefit of the Acquiror on forms previously provided to the Company by the
Acquiror, and the other Specified Consents shall be in the name of the Acquiror
as assignee, be effective upon the Closing and comply in wording with the
concept set forth in clause (a) of the definition of Assumed Liabilities on a
form to be provided by the Acquiror.

     4.10 Termination Expenses. The Company shall pay any "early termination
fee" required to terminate the Receivables Sales Agreement dated as of October
8, 1998 between the Company and RFC Capital Corporation, and all other fees,
expenses, costs and amounts necessary to deliver the Acquired Assets at the
Closing as set forth in Section 2.1 and this Agreement.

5. Post-Closing Covenants. The parties agree as follows with respect to the
period following the Closing.

     5.1. Further Assurances. In case at any time after the Closing any further
action is necessary or desirable to carry out the purposes of this Agreement,
each of the parties will take such further action (including the execution and
delivery of such further instruments and documents) as any other party
reasonably may request, all at the sole cost and expense of the requesting party
(unless the requesting party is entitled to indemnification therefor under
Section 7).

     5.2. Transition. Neither the Company nor the Shareholder will take any
action at any time that is designed or intended to have the effect of
discouraging any customer, supplier, lessor, licensor or other business
associate of the Company, UST or VNS from establishing or continuing a business
relationship with the Acquiror or PentaStar after the Closing.

     5.3. Cooperation. In the event and for so long as any party actively is
contesting or defending against any action, suit, proceeding, hearing,
investigation, charge, complaint, claim or demand in connection with (a) any
transaction contemplated by this Agreement or (b) any fact, situation,
circumstance, status, condition, activity, practice, plan, occurrence, event,
incident, action, failure to act or transaction on or prior to the Closing
involving any of the Acquired Assets or the Company's business, each of the
other parties will cooperate with such party and its counsel in the contest or
defense, make available their personnel, and provide such testimony and access
to their books and records as shall be reasonably necessary in connection with
the contest or defense, all at the sole cost and expense of the contesting or
defending party (unless the contesting or defending party is entitled to
indemnification therefor under Section 7).

     5.4. Confidentiality. The Company and the Shareholder will treat and hold
as confidential all Confidential Information concerning PentaStar, the Company's
business, the business represented by the UST Assets and the VNS Assets or the
Acquired Assets, refrain from using any such Confidential Information and
deliver promptly to PentaStar or destroy, at the request and option of
PentaStar, all of such Confidential Information in its or their possession.

     5.5. Financial Statements. Upon request of PentaStar, the Company and the
Shareholder will, and will use commercially reasonable efforts to cause UST and
VNS to, cooperate with PentaStar and render such assistance to PentaStar and its
accountants as may be required to produce such historical and on-going financial
statements and audits as PentaStar may request, including, without limitation,
signing (or in the case of UST and VNS using commercially reasonable efforts to
cause to be signed) management representation letters reasonably requested by
PentaStar's auditors, all at the sole cost and expense of PentaStar, but without
additional consideration to the Company, UST, VNS or the Shareholder. The
Company and the Shareholder

                                      -20-

<PAGE>   25



acknowledge that PentaStar may be required by applicable law to include audited
financial statements with respect to the business of the Company, UST and VNS in
reports filed with governmental agencies and that the inability to audit the
financial statements as of the Effective Date promptly after the Closing could
have a material adverse effect on PentaStar.

     5.6. Satisfaction of Liabilities. The Company and the Shareholder will pay
and perform, as and when due, all Liabilities (other than the Assumed
Liabilities) relating to the Company, the business of the Company and the
Acquired Assets, including without limitation, all Taxes attributable to the
transactions contemplated by this Agreement and all accrued vacation and other
accrued employee benefits. Further, the Company and the Shareholder, at their
expense, promptly will take or cause to be taken any action necessary to remedy
any failure of the Premises or the acquired business to comply at the Closing
with any Legal Requirement, upon receipt of notice from PentaStar at any time.
The Acquiror will pay and perform, as and when due (except to the extent the
validity thereof or the liability therefor is being contested by the Acquiror),
the Assumed Liabilities.

     5.7. Repurchase of Unpaid Receivables. The Company and the Shareholder
jointly and severally guarantee that Closing Accounts Receivable in at least the
aggregate net amount set forth on Exhibit 1.1(e) (the "Aggregate Net Amount")
will be paid to the Acquiror not later than 180 days from the Closing Date. Upon
demand (the "Payment Demand") by PentaStar at any time after 180 days from the
Closing Date, the Company and the Shareholder shall jointly and severally pay to
the Acquiror the amount of any shortfall (a "Shortfall Payment") between the
Aggregate Net Amount and the aggregate payments received by the Acquiror from
account obligors in respect of the Closing Accounts Receivable. Payments
received by the Acquiror from such account obligors will be applied to the
Closing Accounts Receivable specified by the account obligors in connection with
such payment. If the Acquiror receives a Shortfall Payment from the Company or
the Shareholder and the Acquiror thereafter receives payment from an account
obligor in respect of a Closing Account Receivable (a "Post-Indemnification
Payment") in respect of which such Shortfall Payment was made, the Acquiror will
promptly deliver the amount of such Post-Indemnification Payment to the Company;
provided, however, that the aggregate amount of all Post-Indemnification
Payments made by the Acquiror to the Company will not exceed the amount of the
Shortfall Payment. Upon delivery of the Shortfall Payment to the Acquiror, the
Closing Accounts Receivable identified by PentaStar in the Payment Demand (and
PentaStar shall so identify the oldest Closing Accounts Receivable first) shall,
without further action of any party, become the property of the Company and the
Shareholder, who may pursue collection thereof; provided, however, that the
Shareholder and the Company shall notify the account obligor that such
collection efforts are not being undertaken on behalf of the Acquiror. From the
Closing until 180 days after the Closing Date, PentaStar (through the Acquiror)
will apply the Company's standard accounts receivable collection procedures to
the Closing Accounts Receivable; provided, however, neither the Acquiror nor
PentaStar will not be required to institute suit, utilize third-party collection
agencies or other agents or take other extraordinary collection actions with
respect to the Closing Accounts Receivable; and, provided further, that any
failure of any collection activities of the Acquiror, PentaStar or any such
collection agency or other agent will not relieve the Company or the Shareholder
from their guarantee of the Closing Accounts Receivable as described in this
Section 5.7. The Acquiror will make available to the Company and the
Shareholder, during normal business hours as reasonably requested by the
Company, such of the Acquiror's books and records as are necessary to allow the
Company and the Shareholder, at their expense, to confirm the amount of the
Shortfall Payment demanded by PentaStar and the existence of any
Post-Indemnification Payment received by the Acquiror from an account obligor in
respect of such account obligor's Closing Account Receivable.

     5.8. Transfer Restrictions. Unless otherwise agreed by PentaStar, except
for the transfer of the Rowley Shares to Brian S. Rowley pursuant to Section
2.3(b)(iii), the Company will not sell, assign, exchange, transfer, pledge or
otherwise dispose of at any time prior to the date which is 18 months after the
Closing any of the PentaStar Shares received by the Company as part of the
Purchase Price, whether such shares are Closing Shares or are issued pursuant to
Section 2.3(b)(iii). Thereafter, up to 33.33% of the Total VSIN Shares may be
resold at any time, and an additional 33.33% of the Total VSIN Shares may be
resold beginning 24 months after the Closing. Any remaining Total VSIN Shares
may not be sold until the earlier to occur of (x) sale of all or substantially
all of the assets or outstanding shares of PentaStar or (y) 30 months after the
Closing. Certificates for the PentaStar Shares issued to the Company pursuant to
the Agreement will bear a legend substantially in the form set forth below as
long as applicable:

THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO THAT CERTAIN PURCHASE
AGREEMENT DATED AS OF FEBRUARY __, 2000 (THE "AGREEMENT"), BY AND AMONG THE
ISSUER, OC MERGERCO 4, INC., VSI NETWORK SOLUTIONS, INC. AND SHAREHOLDER OF VSI
NETWORK SOLUTIONS, INC. PRIOR TO THE EXPIRATION OF THE HOLDING PERIOD SET FORTH
IN THE AGREEMENT, SUCH SHARES MAY NOT BE SOLD, ASSIGNED, EXCHANGED, TRANSFERRED,
PLEDGED OR OTHERWISE DISPOSED OF WITHOUT THE WRITTEN CONSENT OF THE ISSUER, AND
THE ISSUER SHALL NOT BE REQUIRED TO GIVE EFFECT TO ANY ATTEMPTED SALE,
ASSIGNMENT, EXCHANGE, TRANSFER, PLEDGE OR OTHER DISPOSITION WHICH VIOLATES THE
AGREEMENT. UPON THE WRITTEN REQUEST OF THE HOLDER OF THIS CERTIFICATE, THE
ISSUER AGREES TO REMOVE THIS RESTRICTIVE LEGEND (AND ANY STOP ORDER RELATING TO
THIS RESTRICTIVE LEGEND PLACED WITH THE TRANSFER AGENT) WHEN THE APPLICABLE
HOLDING PERIOD HAS EXPIRED.

     PentaStar shall issue separate certificates to the Company representing the
shares of PentaStar Shares subject to each of the three periods of restriction
contemplated by this Section 5.8.

     The restrictions set forth along in this Section 5.8 shall be in addition
to any restrictions on transfer imposed by the Securities Act and applicable
state securities laws. The Company also agrees to comply with such restrictions.

     5.9 Certain Provider Matters. Notwithstanding any other provision of this
Agreement, if during the period ending on June 30, 2000, any Person who is a
service provider to the Acquiror at any time during the period ending June 30,
2000 (who was also a service provider to the Company, UST or VNS prior to the
Closing) changes or terminates its relationship with the Acquiror, and such
change or termination results in Adverse Consequences to the Acquiror or
PentaStar, then the Company and the Shareholder agree to jointly and severally
indemnify the Acquiror and PentaStar from such Adverse Consequences. The
Shareholder's Agent shall be entitled to participate in PentaStar's strategy
sessions and PentaStar's negotiating sessions with such service provider in an
effort to minimize or eliminate the Adverse Consequence, subject to PentaStar's
ultimate control with respect to such strategy sessions and negotiating
sessions.

     5.10 Claims Against UST/VNS/View Tech. If PentaStar or the Acquiror asserts
a claim for indemnification against the Company or the Shareholder with respect
to a matter concerning UST, VNS or the UST/VNS Assets, then the Company and the
Shareholder (through the Shareholder's Representative) shall be entitled,
subject to PentaStar's control, to participate in any efforts PentaStar or the
Acquiror may undertake to pursue indemnification from UST, VNS or View Tech;
provided, however, that nothing in this Section 5.10 shall be deemed to
supersede or modify in any way the obligations of the Company and the

                                      -22-

Shareholder under Section 7 or to condition their obligations under Section 7 on

7.   Remedies for Breaches of This Agreement.

     7.1. Indemnification Provisions for Benefit of PentaStar.

         (a) If the Company or the Shareholder breaches (or if any Person other
than PentaStar or the Acquiror alleges facts that, if true, would mean the
Company or the Shareholder has breached) any of the representations or
warranties of the Company or the Shareholder contained herein and PentaStar
gives notice thereof to the Shareholder's Agent within the Survival Period, or
if the Company or the Shareholder breaches (or if any Person other than
PentaStar or the Acquiror alleges facts that, if true, would mean the Company or
the Shareholder has breached) any covenants of the Company or the Shareholder
contained herein or any representations, warranties or covenants of the Company
or the Shareholder contained in any Other Seller Agreement and PentaStar gives
notice thereof to the Shareholder's Agent, or if UST, VNS or View Tech breaches
any of their covenants (including, without limitation, covenants regarding
indemnification) set forth in the UST/VNS Acquisition Agreement and PentaStar
gives notice thereof to the Shareholder's Agent, then the Company and the
Shareholder agree to jointly and severally indemnify and hold harmless PentaStar
and the Acquiror from and against any Adverse Consequences PentaStar or the
Acquiror may suffer resulting from, arising out of, relating to or caused by any
of the foregoing regardless of whether the Adverse Consequences are suffered
during or after the Survival Period. In determining whether there has been a
breach of any representation or warranty contained in Section 3.1 and in
determining for purposes of the preceding sentence the amount of Adverse
Consequences suffered by PentaStar or the Acquiror, such representations and
warranties shall not be qualified (other than by the reference to "knowledge"
set forth in the last sentence of Section 3.1(o)) by "material," "materiality,"
"in all material respects," "best knowledge," "best of knowledge" or "knowledge"
or words of similar import, or by any phrase using any such terms or words. The
Company and the Shareholder also agree to jointly and severally indemnify and
hold harmless PentaStar and the Acquiror from and against any Adverse
Consequences PentaStar or the Acquiror may suffer which result from, arise out
of, relate to or are caused by (i) any Liability of the Company, UST, VNS or the
Shareholder not included in the Assumed Liabilities, or (ii) any condition,
circumstance or activity existing prior to the Closing which relates to any
Legal Requirement or any act or omission of the Company, UST, VNS, or any
current or former shareholder of the Company or any predecessor with respect to,
or any event or circumstance related to, the Company's, UST's, VNS's, any
current or former shareholder's or any predecessor's ownership, use or operation
of any of the Acquired Assets, the Premises or any other assets or properties or
the conduct of its or their business, regardless, in the case of (i) or (ii), of
(A) whether or not such Liability, act, omission, event, circumstance or matter
was known or disclosed to PentaStar, was disclosed on any Exhibit hereto or is a
matter with respect to which the Company or the Shareholder did or did not have
knowledge, (B) when such Liability, act, omission, event, circumstance or matter
occurred, existed, occurs or exists and (C) whether a claim with respect thereto
was asserted before or is asserted after the Closing and (iii) any Liability
resulting from any failure of the parties to comply with any applicable bulk
sales or transfer Legal Requirement in connection with the transactions
contemplated by this Agreement. The Company and the Shareholder acknowledge and
agree that the fact that they have made disclosures pursuant to Section 3.1 or
otherwise of matters, or did not have knowledge of matters, which result in
Adverse Consequences to PentaStar or the Acquiror shall not relieve the Company
and the Shareholder of their obligation pursuant to this Section 7 to indemnify
and hold PentaStar and the Acquiror harmless from

                                      -25-

<PAGE>   30



all Adverse Consequences. Matters disclosed on an Exhibit referenced in Section
3.1 are deemed to be part of the corresponding representation for purposes of
determining the breach or non-breach of such representation, but such disclosure
shall not relieve the Company and the Shareholder from their obligation to
indemnify PentaStar and the Acquiror pursuant to the preceding provisions of
Section 7.1(a) from the matter disclosed except to the extent such matter
constitutes an Assumed Liability. If any dispute arises concerning whether any
indemnification is owing which cannot be resolved by negotiation among the
parties within 30 days of notice of claim for indemnification from the party
claiming indemnification to the party against whom such claim is asserted, the
dispute will be resolved by arbitration pursuant to this Agreement.

         (b) (i) Amounts needed to satisfy the obligations of the Company and
the Shareholder under Section 5.7 during the Escrow Period shall be paid to the
Acquiror first out of the Accounts Receivable Escrow Fund, then by the Company
and the Shareholder. The Company and the Shareholder shall have joint and
several Liability for any additional amounts needed to cover such obligations,
which amounts shall be paid directly to the Acquiror. At the end of the Escrow
Period, amounts of the Accounts Receivable Escrow Fund which may be needed to
cover pending indemnification claims with respect to Section 5.7 made by
PentaStar (such amounts to be determined by PentaStar in accordance with Section
5.7) shall be retained in the Accounts Receivable Escrow Fund until such claims
are resolved, and any excess of the Accounts Receivable Escrow Fund shall be
paid to the Company.

             (ii) Except as provided in Section 7.1(b)(i), amounts needed to
cover any indemnification claims resolved in favor of PentaStar or the Acquiror
against the Company or the Shareholder during the Escrow Period shall be paid to
PentaStar first out of the cash portion of the Purchase Price from the Company
and the Shareholder and then out of the Escrow Deposit, along with interest from
the date the party seeking indemnification gives notice thereof to the
indemnifying party at the rate equal to two percentage points above the prime
rate quoted by PentaStar's principal lender from time to time if such interest
rate amount is not already included in the indemnification claim pursuant to the
definition of Adverse Consequences. The Company and the Shareholder shall have
joint and several Liability for any amounts of cash needed to cover such claims,
which amounts shall be paid directly to PentaStar. At the end of the Escrow
Period, amounts of the Escrow Deposit which may be needed to cover pending
indemnification claims made by PentaStar (such amounts to be determined by
PentaStar based upon the reasonable exercise of its business judgment) shall be
retained in the Escrow Account until such claims are resolved, and any excess of
the Escrow Deposit shall be paid to the Company. For purposes of indemnification
claims, each of the Total VSIN Shares shall be valued at the per share price at
which it was issued pursuant to Section 2.3(a) or 2.3(b)(iii), as applicable,
and the Closing Shares shall be deemed to be the first shares subject to such
claims for purposes of such calculation. Subject to Section 7.1(b)(i), the
Escrow Deposit shall also be available to satisfy the obligations of the Company
and the Shareholder under Section 5.7.

             (iii) Nothing in this Section 7.1(b) shall be construed to limit
PentaStar's or the Acquiror's right to indemnification to amounts on deposit in
the Accounts Receivable Escrow Fund or the Escrow Account. PentaStar and the
Shareholder's Agent shall jointly give instructions to the Escrow Agent to carry
out the intent of this Section 7.1(b). Any disputes concerning the escrowed
property shall be settled by arbitration as provided in this Agreement.
PentaStar, on the one hand, and the Company and the Shareholder jointly and
severally, on the other hand, shall each be responsible for one-half of the
fees, charges and expenses payable to the Escrow Agent pursuant to paragraph a.
of Article 2 of the Escrow Agreement and, except as otherwise determined
pursuant to Section 9.11 of this Agreement, one-half of any amounts payable
pursuant to paragraph b. of such Article 2.

             (c) PentaStar and the Acquiror shall not assert a claim for
indemnification against the Company or the Shareholder until the aggregate
amount of all Adverse Consequences previously suffered by PentaStar or the
Acquiror in respect of all matters indemnifiable under Section 7.1(a) exceeds
$25,000, at which point PentaStar and the Acquiror shall be entitled to be
indemnified in full, including for all matters comprising the initial $25,000 of
Adverse Consequences not previously asserted. The aggregate indemnification
obligation of the Company and the Shareholder pursuant to Section 7.1(a) shall
be limited to the Purchase Price.

     7.2. Indemnification Provisions for Benefit of the Company and the
Shareholder.

         (a) If PentaStar breaches (or if any Person other than the Company or
the Shareholder alleges facts that, if true, would mean PentaStar has breached)
any of its representations or warranties contained herein and the Shareholder's
Agent gives notice of a claim for indemnification against PentaStar within the
Survival Period, or if PentaStar breaches (or if any Person other than the
Company or the Shareholder alleges facts that, if true, would mean PentaStar has
breached) any of its covenants contained herein or any of its representations,
warranties or covenants contained in any Other PentaStar Agreement and the
Shareholder's Agent gives notice thereof to PentaStar, then PentaStar agrees to
indemnify and hold harmless the Company and the Shareholder from and against any
Adverse Consequences the Company and the Shareholder may suffer which result
from, arise out of, relate to, or are caused by the breach or alleged breach,
regardless of whether the Adverse Consequences are suffered during or after the
Survival Period. In determining whether there has been a breach of any
representation or warranty contained in Section 3.2 and in determining the
amount of Adverse Consequences suffered by the Company and the Shareholder for
purposes of this Section 7.2, such representations and warranties shall not be
qualified by "material," "materiality," "in all material respects," "best
knowledge," "best of knowledge" or "knowledge" or words of similar import, or by
any phrase using any such terms or words. Matters disclosed on an Exhibit
referenced in Section 3.2 are deemed to be part of the corresponding
representation for purposes of determining the breach or non-breach of such
representation. If any dispute arises concerning whether any indemnification is
owing which cannot be resolved by negotiation among the parties within 30 days
of notice of claim for indemnification from the party claiming indemnification
to the party against whom such claim is asserted, the dispute will be resolved
by arbitration pursuant to this Agreement.

         (b) The Company and the Shareholder shall not assert a claim for
indemnification against PentaStar until the aggregate amount of all Adverse
Consequences previously suffered by the Company and the Shareholder in respect
of all matters indemnifiable under Section 7.2(a) exceeds $25,000 (exclusive of
amounts which are part of the Purchase Price), at which point the Company and
the Shareholder shall be entitled to be indemnified in full, including for all
matters comprising the initial $25,000 of Adverse Consequences not previously
asserted. The aggregate indemnification obligation of PentaStar pursuant to
Section 7.1(a) shall be limited to the Purchase Price.

     7.3. Matters Involving Third Parties.

         (a) If any Person not a party to this Agreement (including, without
limitation, any Governmental Authority) notifies any party (the "Indemnified
Party") with respect to any matter (a "Third Party Claim") which may give rise
to a claim for indemnification against any other party (the "Indemnifying
Party"), then the Indemnified Party will notify each Indemnifying Party thereof
in writing within 15 days after receiving such notice. No delay on the part of
the Indemnified Party in notifying any Indemnifying Party will relieve the
Indemnifying Party from any obligation hereunder unless (and then solely to the
extent) the Indemnifying Party thereby is prejudiced.

         (b) Any Indemnifying Party will have the right, at its sole cost and
expense, to defend the Indemnified Party against the Third Party Claim with
counsel of its choice satisfactory to the Indemnified Party so long as (i) the
Indemnifying Party notifies the Indemnified Party in writing within 10 days
after the Indemnified Party has given notice of the Third Party Claim that the
Indemnifying Party will indemnify the Indemnified Party from and against the
entirety of any Adverse Consequences the Indemnified Party may suffer resulting
from, arising out of, relating to or caused by the Third Party Claim, (ii) the
Indemnifying Party provides the Indemnified Party with evidence reasonably
acceptable to the Indemnified Party that the Indemnifying Party will have the
financial resources to defend against the Third Party Claim and fulfill its
indemnification obligations hereunder (subject to the limitations set forth in
Section 7.1(c) and 7.2(b)), (iii) the Third Party Claim involves only money
damages and does not seek an injunction or other equitable relief, (iv)
settlement of, or an adverse judgment with respect to, the Third Party Claim is
not, in the good faith judgment of the Indemnified Party, likely to establish a
precedential custom or practice materially adverse to the continuing business
interests of the Indemnified Party, and (v) the Indemnifying Party conducts the
defense of the Third Party Claim actively and diligently. If the Indemnifying
Party does not assume control of the defense or settlement of any Third Party
Claim in the manner described above, it will be bound by the results obtained by
the Indemnified Party with respect to the Third Party Claim.

         (c) So long as the Indemnifying Party is conducting the defense of the
Third Party Claim in accordance with Section 7.3(b) above, (i) the Indemnified
Party may retain separate co-counsel at its sole cost and expense and
participate in the defense of the Third Party Claim, (ii) the Indemnified Party
will not consent to the entry of any judgment or enter into any settlement with
respect to the Third Party Claim without the prior written consent of the
Indemnifying Party (not to be withheld unreasonably), and (iii) the Indemnifying
Party will not consent to the entry of any judgment or enter into any settlement
with respect to the Third Party Claim without the prior written consent of the
Indemnified Party (not to be withheld unreasonably).

         (d) In the event any of the conditions in Section 7.3(b) above is or
becomes unsatisfied, however, (i) the Indemnified Party may defend against, and
consent to the entry of any judgment or enter into any settlement with respect
to, the Third Party Claim in any manner it reasonably may deem appropriate (and
the Indemnified Party need not consult with, or obtain any consent from, any
Indemnifying Party in connection therewith), (ii) the Indemnifying Parties will
reimburse the Indemnified Party promptly and periodically for the costs of
defending against the Third Party Claim (including reasonable attorneys' fees
and expenses), and (iii) the Indemnifying Parties will remain responsible for
any Adverse Consequences the Indemnified Party may suffer resulting from,
arising out of, relating to or caused by the Third Party Claim to the fullest
extent provided in this Section 7.

     7.4. Right of Offset. PentaStar and the Acquiror will have the right to
offset any Adverse Consequences either of them may suffer against any amounts
payable (including amounts payable in the form of PentaStar Common Stock)
pursuant to this Agreement or any Other Seller Agreement to the Company, the
Shareholder or any relative or affiliate of the Company or the Shareholder at or
after the Closing.

     7.5. Other Remedies. The foregoing indemnification provisions are in
addition to, and not in derogation of, any statutory, equitable or common law
remedy any party may have.

8.   Termination.

     8.1. Termination of Agreement. The parties may terminate this Agreement as
provided below:

         (a) PentaStar and the Shareholder's Agent may terminate this Agreement
by mutual written consent at any time prior to the Closing; or

         (b) PentaStar may terminate this Agreement by giving written notice to
the Shareholder's Agent at any time prior to the Closing (i) in the event the
Company or the Shareholder has breached any representation (given as of the date
of this Agreement), warranty or covenant contained in this Agreement in any
material way, PentaStar has notified the Shareholder's Agent of the breach, and
the breach has not been cured within 10 days after the notice of breach or (ii)
if the Closing has not occurred on or before May 31, 2000 because of the failure
of any condition precedent to PentaStar's obligations to consummate the Closing
(unless the failure results primarily from PentaStar breaching any
representation, warranty or covenant contained in this Agreement in any material
way).

     8.2. Effect of Termination. The termination of this Agreement by a party
pursuant to Section 8.1 will in no way limit any obligation or liability of any
other party based on or arising from a breach or default by such other party
with respect to any of its representations, warranties, covenants or agreements
contained in this Agreement, and the terminating party will be entitled to seek
all relief to which it is entitled under applicable law.

     8.3. Confidentiality. If this Agreement is terminated, each party will
treat and hold as confidential all Confidential Information concerning the other
parties which it acquired from such other parties in connection with this
Agreement and the transactions contemplated hereby.

rights or remedies upon any Person other than the parties and their respective
successors and permitted assigns.

herein) constitutes the entire agreement among the parties and supersedes any

hereof.

     9.3. Succession and Assignment. This Agreement will be binding upon and
inure to the benefit of the parties and their respective successors and
permitted assigns. Neither the Company nor the Shareholder may assign this
Agreement or any of its, his or her rights, interests or obligations hereunder
without the prior written approval of PentaStar. PentaStar and the Acquiror may
assign their respective rights and obligations hereunder as permitted by law,
including, without limitation, to any debt or equity financing source.

performance or other equitable relief, will be submitted to binding arbitration
in Denver, Colorado before the Judicial Arbiter Group, but under the Commercial
Arbitration Rules of the American Arbitration Association under the authority of
federal and state arbitration statutes, and shall not be the subject of
litigation in any forum. If the Judicial Arbiter Group is unavailable to conduct
the arbitration or is unsatisfactory to a party in its good faith judgment, then
it shall be before another arbitral body in Denver, Colorado selected by
PentaStar and the Shareholder's Agent or, if they cannot agree on another
arbitral body, the American Arbitration Association. EACH PARTY, BY SIGNING THIS
AGREEMENT, VOLUNTARILY, KNOWINGLY AND INTELLIGENTLY WAIVES ANY RIGHTS SUCH PARTY

Requirement. The decision of the arbitrators will be final and binding, and
judgment on the award by the arbitrators may be entered in any court of
competent jurisdiction. THIS SUBMISSION AND AGREEMENT TO ARBITRATE WILL BE

arbitration or in any action to enforce this Agreement will be entitled to

and attorneys, incurred in connection therewith. If each party prevails on
specific issues in the arbitration, the arbitrator may allocate the costs
incurred by all parties on a basis the arbitrator deems appropriate.

     9.12. Construction. The parties have participated jointly in the
negotiation and drafting of this Agreement. In the event an ambiguity or
question of intent or interpretation arises, this Agreement will be construed as
if drafted jointly by the parties and no presumption or burden of proof will
arise favoring or disfavoring any party by virtue of the authorship of any of
the provisions of this Agreement. The word "including" will mean including
without limitation. The parties intend that each representation, warranty and
covenant contained herein will have independent significance. If any party
breaches any representation,

                                      -31-

<PAGE>   36



warranty or covenant contained herein in any respect, the fact that there exists
another representation, warranty or covenant relating to the same subject matter
(regardless of the relative levels of specificity) which the party has not
breached will not detract from or mitigate the fact that the party is in breach
of the first representation, warranty or covenant.

     9.13. Incorporation of Exhibits. The Exhibits identified in this Agreement
are incorporated herein by reference and made a part hereof.

     9.14. Shareholder's Agent. The Company and the Shareholder hereby authorize
and appoint the Shareholder's Agent as its exclusive agent and attorney-in-fact
to act on behalf of each of them with respect to all matters which are the
subject of this Agreement or any Other Seller Agreement, including, without
limitation, (a) receiving or giving all notices, instructions, other
communications, consents or agreements that may be necessary, required or given
hereunder and (b) asserting, settling, compromising, or defending, or
determining not to assert, settle, compromise or defend, (i) any claims which
the Company or the Shareholder may assert, or have the right to assert, against
PentaStar or the Acquiror, or (ii) any claims which PentaStar or the Acquiror
may assert, or have the right to assert, against the Company or the Shareholder.
The Shareholder's Agent hereby accepts such authorization and appointment. Upon
the receipt of written evidence satisfactory to PentaStar to the effect that the
Shareholder's Agent has been substituted as agent of the Company and the
Shareholder by reason of his death, disability or resignation, PentaStar shall
be entitled to rely on such substituted agent to the same extent as they were
theretofore entitled to rely upon the Shareholder's Agent with respect to the
matters covered by this Section 9.14. Neither the Company nor the Shareholder
shall act with respect to any of the matters which are the subject of this
Agreement or any Other Seller Agreement except through the Shareholder's Agent.
The Company and the Shareholder acknowledge and agree that PentaStar and the
Acquiror may deal exclusively with the Shareholder's Agent in respect of such
matters, that the enforceability of this Section 9.14 is material to PentaStar
and the Acquiror, and that PentaStar and the Acquiror have relied upon the
enforceability of this Section 9.14 in entering into this Agreement.

                  (b) Certificate of Incorporation. At the Closing Date, the
Certificate of Incorporation of PentaStar, as in effect immediately prior to the

                  (c) Bylaws. At the Closing Date, the Bylaws of PentaStar, as

Law.

                  (d) Directors. At the Closing Date, the directors of PentaStar
immediately prior to the Closing Date will continue to be the directors of the
Surviving Corporation, each to hold office in accordance with the Certificate of
Incorporation and Bylaws of the Surviving Corporation and the Delaware General

his or her successor is duly elected and qualified, as the case may be.

                  (e) Officers. At the Closing Date, the officers of PentaStar
immediately prior to the Closing Date will continue to be the officers of the
Surviving Corporation, each to hold office in accordance with the Certificate of
Incorporation and Bylaws of the Surviving Corporation and the Delaware General

the Excluded Liabilities pursuant to Sections 4.7 and 4.8, all the properties,
rights, privileges, powers, and franchises of the Company as of that date will
vest in the Surviving Corporation, and all debts, liabilities, and duties of the
Company will become the debts, liabilities, and duties of the Surviving
Corporation.

                  (g) Documents. Subject to the terms and conditions in this
Agreement, the parties shall prepare, sign, and acknowledge, in accordance with
the Delaware General Corporation Law and the corporate laws of the State of
Arizona, a certificate of merger (the "Certificate of Merger") and the plan and
articles of merger (the "Plan and Articles of Merger") and deliver the
Certificate of Merger to the Secretary of State of the State of Delaware for
filing pursuant to the Delaware General Corporation Law on the Closing Date and
the Plan and Articles of Merger to the Corporation Commission of the State of
Arizona for filing pursuant to the Arizona Revised Statutes on the Closing Date,
with subsequent publication and filing of an affidavit of publication in
accordance with the terms of Arizona Revised Statutes Section 10-1105. The
Merger shall be completed upon the filing of the Certificate of Merger with the
Secretary of State of the State of Delaware and of the Articles of Merger with
the Corporation Commission of the State of Arizona, subject to publication and
filing of an affidavit of publication, but shall be effective for economic and
accounting purposes as of January 1, 2000. PentaStar agrees to file such
documents with the Secretary of State of the State of Delaware and the Arizona
Corporation Commission and thereafter to publish notice of the Merger and file
an affidavit of publication with the Arizona Corporation Commission as required
by Arizona law.

                  (h) Share Conversion. At the Closing Date, by virtue of the
Merger and without any action on the part of the holder of any shares of capital
stock of any corporation, each issued and outstanding share of capital stock of
the Company will be converted into the right to receive a portion of the
consideration


                                     - 2 -
<PAGE>   8

payable pursuant to Section 2.1(k) determined by dividing the aggregate
consideration so payable by the number of shares of capital stock of the Company
outstanding at the Closing Date; provided, however, that each issued and
outstanding share of the capital stock of the Company owned directly or
indirectly by the Company as treasury stock, if any, will be cancelled and
retired, and no cash, PentaStar Shares or other consideration shall be delivered
or payable in exchange therefor. Each share of the capital stock of PentaStar
issued and outstanding immediately prior to the Closing Date will remain issued
and outstanding.

                  (i) No Fractional Shares. No certificates or scrip
representing fractional shares of any class of PentaStar Shares will be issued
pursuant to the Merger. Such fractional share interests shall not entitle the
owner thereof to any rights as a security holder of PentaStar. In lieu of any
such fractional shares of any class of PentaStar Shares each Shareholder
entitled to receive PentaStar Shares in the Merger pursuant to this Agreement
will be entitled to receive an amount in cash (without interest), rounded to the
nearest cent, determined by multiplying the value of a PentaStar Share issuable
pursuant to this Agreement (as set forth in Section 2.1(k) or, in the case of
PentaStar Shares issued as part of the Earn-Out Amount, as determined pursuant
to Section 2.1(n)) by the fractional interest in such PentaStar Shares to which
such Person would otherwise be entitled.

                  (j) Certain Information. Attached as Exhibit 2.1(j) is a
schedule of (A) expenses incurred by the Company (determined in accordance with
GAAP) in connection with the Retained Operations during the period from the
Effective Date to the Closing Date that have actually been paid prior to the
Closing Date (estimated to the extent necessary), (B) sales commissions paid by
the Company during such period in respect of cash received by the Company during
such period relating to the Retained Operations, (C) cash receipts of the
Company during such period relating to the Retained Operations (estimated to the
extent necessary) and (D) a calculation of the estimated Net Cash Adjustment
based on the information described in (A) through (C) above.

                  (k) Consideration. Subject to adjustment as provided in
Section 2.1(m), the aggregate consideration payable to the Shareholders pursuant
to the Merger will be as follows: (a) cash in the amount of (1) $500,000, plus
or minus (2) 50% of the estimated Net Cash Adjustment set forth on Exhibit
2.1(j) (the amount described in this clause (a) being referred to as the "Cash
Portion" of the Purchase Price); plus (b) a number of shares of PentaStar Common
Stock (rounded to the nearest whole share) determined by dividing (1) the sum of
$500,000 plus or minus 50% of the estimated Net Cash Adjustment set forth on
Exhibit 2.1(j) by (2) the Fair Market Value of the PentaStar Common Stock as of
the Closing Date (the "Closing Shares"); plus (c) the Earn-Out Amount payable
pursuant to Section 2.1(n) (collectively the "Purchase Price"). The Purchase
Price will be adjusted in accordance with Section 2.1(m), and will be payable
and issuable to the Shareholders in accordance with the following percentages:

On the Closing Date PentaStar will (i) pay to the Shareholders by wire transfer
to an account or accounts designated by the Shareholders (in accordance with the
percentages set forth above) the Cash Portion of the Purchase Price; and (ii)
issue the Closing Shares to the Shareholders (in the percentages set forth
above). On the Closing Date, the Shareholders will deposit the Closing Shares
with the Escrow Agent pursuant to the Escrow Agreement. In addition, on the
Closing Date, each Shareholder shall designate a number of Closing Shares, not
less than 25% nor more than 50% of the total Closing Shares received by such
Shareholder, to be subject to the Principal Shareholder's Escrow Agreement. The
Principal Shareholder's Escrow Agreement provides that upon the occurrence of
certain conditions, a Shareholder may receive a greater or lesser number of
shares of PentaStar Common Stock than the number initially deposited with
PentaStar pursuant to the Principal Shareholder's Escrow Agreement. The parties
agree that any adjustment in the number of such shares will be treated as an
adjustment to the Purchase Price. Because the Closing Shares will be held by the
Escrow Agent pursuant to the Escrow Agreement, they will initially not be
available for delivery to PentaStar as contemplated by the Principal
Shareholder's Escrow Agreement. However, as soon as any such Closing Shares are
released from the Escrow Agreement for delivery to any Shareholder, they shall
be delivered to PentaStar until the number of Closing Shares so delivered for
each Shareholder equals the number of Closing Shares designated by that
Shareholder to be subject to the Principal Shareholder's Escrow Agreement. In
the event that any such Closing Shares are delivered to PentaStar in
satisfaction of the indemnification obligations of the Shareholders under this
Agreement, or in satisfaction of any other obligation to PentaStar secured by
such shares, the number of shares subject to the Principal Shareholder's Escrow
Agreement for each Shareholder shall be proportionately reduced. The number of
shares subject to the Principal Shareholder's Escrow Agreement for each
Shareholder following such reduction shall be determined by multiplying the
number of Closing Shares originally designated by such Shareholder to be subject
to the Principal Shareholder's Escrow Agreement by a fraction, the numerator of
which is the total number of Closing Shares owned by such Shareholder that
remain in the Escrow Deposit after such delivery (plus any Closing Shares
previously released from the Escrow Deposit for delivery to such Shareholder)
and the denominator of which is the total number of Closing Shares issued to
such Shareholder.

                  (l) Adjustment Financial Statements. Within 60 days after the
Closing Date an audited balance sheet for the Company will be prepared as of
December 31, 1999 (the "Audited Effective Date Balance Sheet") and delivered to
PentaStar and the Shareholders. The Audited Effective Date Balance Sheet will be
prepared by Arthur Andersen LLP in accordance with GAAP on a basis consistent
with the historical accounting practices of PentaStar. The Audited Effective
Date Balance Sheet will set forth, in addition to other items required by GAAP,
a detailed listing of the liabilities of the Company as of the Effective Date.
Within 60 days after the Closing Date, PentaStar shall also prepare (or cause
Arthur Andersen LLP to prepare) and deliver to the Shareholders a schedule of
expenses incurred by the Company (determined in accordance with GAAP) in
connection with the Retained Operations during the period from the Effective
Date to the Closing Date that were actually paid prior to the Closing Date,
sales commissions paid by the Company during such period in respect of cash
received by the Company during such period relating to the Retained Operations,
and cash receipts of the Company during such period relating to the Retained
Operations, together with a calculation of the Net Cash Adjustment. The Audited
Effective Date Balance Sheet and such schedule are referred to collectively as
the "Adjustment Financial Statements." PentaStar will pay the fees and expenses
of Arthur Andersen LLP incurred in connection with the preparation of the
Adjustment Financial Statements. Within 20 days after receipt of the Adjustment
Financial Statements, each of PentaStar and the Shareholders will, in a written
notice to the other either accept the Adjustment Financial Statements or object
to them by describing in reasonably specific detail any proposed adjustments to
the Adjustment Financial Statements and the estimated amounts of and reasons for
such proposed adjustments.


                                     - 4 -
<PAGE>   10

PentaStar shall make the books of the Company available to the Shareholders'
Agent for purposes of reviewing and verifying the Adjustment Financial
Statements. The failure by PentaStar or the Shareholders to object to the
Adjustment Financial Statements within such 20-day period will be deemed to be
an acceptance by such Person of the Adjustment Financial Statements. If any
adjustments to the Adjustment Financial Statements are proposed by PentaStar or
the Shareholders within such 20-day period, the dispute shall be resolved as
provided in Section 2.1(p).

                  (m) Post-Closing Adjustments to the Purchase Price.

                           (i) Within 10 Business Days after the later of the
acceptance of the Adjustment Financial Statements by PentaStar and the
Shareholders or the resolution of any disputes under Section 2.1(p), as the case
may be, the Purchase Price will be redetermined as provided in Section 2.1(k)
based on the Net Cash Adjustment reflected in the Adjustment Financial
Statements. An appropriate adjusting payment shall be made by PentaStar to the
Shareholders or by the Shareholders to PentaStar, as the case may be, so that
the Purchase Price actually paid by PentaStar equals the Purchase Price as so
redetermined. Any such adjusting payment shall be made 50% in cash and 50% in
PentaStar Common Stock, and for that purpose the PentaStar Common Stock shall be
valued at its Fair Market Value as of the Closing Date. If an adjusting payment
is due from PentaStar, the shares of PentaStar Common Stock included in the
payment shall be delivered to the Shareholders and by the Shareholders to the
Escrow Agent for addition to the Escrow Deposit. If an adjusting payment is due
from the Shareholders, PentaStar and the Shareholders' Agent shall execute joint
written instructions to the Escrow Agent to deliver the shares of PentaStar
Common Stock included in such payment to PentaStar from the Escrow Deposit. If
the Audited Effective Date Balance Sheet reflects Excluded Liabilities that
existed as of the Effective Date (other than rent not then due and payable under
the Premises Lease) that have not previously been paid by the Shareholders, such
Excluded Liabilities shall be paid at the time the adjusting payment is made
under this Section 2.1(m)(i), either by PentaStar out of the cash portion of any
adjusting payment due from it hereunder or, if no such payment is due or if the
cash portion of such payment is less than the unpaid Excluded Liabilities, by
the Shareholders. If PentaStar has previously paid any such Excluded Liability,
it shall be reimbursed for such payment at the time the adjusting payment is
made under this Section 2.1(m)(i), either by offset against the cash portion of
any adjusting payment due hereunder or, if no such payment is due or if the cash
portion of such payment is less than the reimbursement amount, by the
Shareholders.

                           (ii) As among themselves, the Shareholders will be
liable for all amounts payable by the Shareholders under this Section 2.1(m) in
proportion to their ownership of Company Shares prior to the Closing. As between
the Shareholders and PentaStar, the Shareholders will be jointly and severally
liable for any amounts payable by the Shareholders under this Section 2.1(m).
Any adjustment in the Purchase Price made under this Section 2.1(m) will be
allocated as an adjustment to the consideration paid for the Company Shares.

                  (n) Earn-Out. In addition to the Cash Portion of the Purchase
Price and the Closing Shares payable and issuable at the Closing pursuant to
this Section 2.1, the Shareholders shall be entitled to receive the Earn-Out
Amount determined and payable as provided in this Section 2.1(n).

                           (i) PentaStar agrees that, during the Earn-Out
Period, it will conduct the Retained Operations in the Phoenix and Tucson,
Arizona metropolitan area as a separate division of PentaStar with


                                     - 5 -
<PAGE>   11

no other operations (the "Partel Division"). The operations of the Partel
Division will be conducted in accordance with the cost structure set forth in
Exhibit 2.1(n) to this Agreement.

                           (ii) As soon as reasonably practicable after the end
of the Earn-Out Period, and in any event by April 30, 2001, PentaStar will cause
the independent auditors who audit its financial statements for the year 2000 to
prepare a separate income statement of the Partel Division for the Earn-Out
Period (which need not be audited) in accordance with GAAP on a basis consistent
with the historical accounting practices of PentaStar, and a written calculation
of the Earn-Out Amount (collectively, the "Earn-Out Financial Statements").
PentaStar will promptly provide a copy of the Earn-Out Financial Statements to
the Shareholders. Within 20 days after receipt of the Earn-Out Financial
Statements, each of PentaStar and the Shareholders will, in a written notice to
the other, either accept the Earn-Out Financial Statements or object to them by
describing in reasonably specific detail any proposed adjustments to the
Earn-Out Financial Statements and the estimated amounts of and reasons for such
proposed adjustments. PentaStar shall make the books of the Partel Division
(and, to the extent relevant, the books of PentaStar) available to the
Shareholders' Agent for purposes of reviewing and verifying the Earn-Out
Financial Statements. The failure by PentaStar or the Shareholders to object to
the Earn-Out Financial Statements within such 20-day period will be deemed to be
an acceptance by such Person of the Earn-Out Financial Statements. If any
adjustments to the Earn-Out Financial Statements are proposed by PentaStar or
the Shareholders within such 20-day period, the dispute shall be resolved as
provided in Section 2.1(p). The fees and expenses of the independent auditors
for the preparation of the Earn-Out Financial Statements will be paid 50% by
PentaStar and 50% by the Shareholders. Such fees and expenses shall not include
any portion of the work done by PentaStar's auditors in connection with its
annual audit.

                           (iii) Within 10 Business Days after the later of the
acceptance of the Earn-Out Financial Statements by PentaStar and the
Shareholders or the resolution of any disputes under Section 2.1(p), as the case
may be, PentaStar will pay the Earn-Out Amount, if any, to the Shareholders. The
Earn-Out Amount shall be payable in PentaStar's sole discretion, in cash or
PentaStar Common Stock, or any combination thereof; provided, however, that (A)
at least 50% of the first $1,000,000 of the Earn-Out Amount shall be paid in
cash and (B) the total amount of cash included in the payment of the Earn-Out
Amount shall not be such as to cause the Purchase Price, taken as a whole, not
to comply with the continuity of interest test for a tax-free reorganization
under Section 368 of the Code, as determined in good faith by PentaStar based on
the advice of counsel. The per share value of the PentaStar Common Stock for
that purpose shall be the remainder of (A) the Fair Market Value of the
PentaStar Common Stock as of the date that the Earn-Out Amount is paid minus (B)
the Company Increase. The cash portion of the Earn-Out Amount shall be paid by
wire transfer to an account or accounts designated by the Shareholders. The
certificates representing the shares of PentaStar Common Stock issued in payment
of the Earn-Out Amount will be mailed to the Shareholders at their addresses for
notice purposes under this Agreement.

                           (iv) In the event that PentaStar sells the operations
conducted by the Partel Division (whether separately or as part of the sale of
all of the assets or operations of PentaStar, and whether in a sale of assets,
by merger or otherwise) prior to the end of the Earn-Out Period, PentaStar shall
require the purchaser to continue to account for such operations separately and
agree to assume the obligations of PentaStar to pay the Earn-Out Amount as
provided in this Section 2.1(n). In that event, the purchaser may pay the
Earn-Out Amount in a combination of cash and such purchaser's common equity
securities based on the fair market value of such securities on the relevant
date as provided in this Section 2.1(n).


                                     - 6 -

                  (o) Post-March Revenues. If PentaStar recognizes revenues
(based on installation) after March 31, 2001 and prior to a PentaStar "valuation
event" (as defined below) in respect of contracts entered into on or after
November 1, 1999 and on or before October 31, 2000, PentaStar will pay to the
Shareholders, as additional consideration for the Company Shares, an amount
equal to four times the remainder of (i) the revenues so recognized minus (ii)
all variable expenses (such as sales commissions) associated with such revenues.
Amounts payable under this Section 2.1(o) shall be paid within 60 days after the
end of the calendar quarter in which the related revenues are recognized by
PentaStar. Each such payment shall be made, in PentaStar's sole discretion, in
cash or PentaStar Common Stock, or any combination thereof; provided, however,
that the amount of cash included in such payments shall not be such as to cause
the Purchase Price, taken as a whole, not to comply with the continuity of
interest test for a tax-free reorganization under Section 368 of the Code, as
determined in good faith by PentaStar based on the advice of counsel. The per
share value of the PentaStar Common Stock for that purpose shall be determined
as provided in Section 2.1(n)(iii), calculated as of the date that the Earn-Out
Amount was paid (or if no Earn-Out Amount was paid, as of April 30, 2001) rather
than the date that such payment is made under this Section 2.1(o). For purposes
of this Section 2.1(o), a PentaStar "valuation event" means the first to occur
of (i) the sale of all or substantially all of the assets or of all of the
outstanding stock of PentaStar, either by way of merger, acquisition or other
method, or (ii) October 26, 2004. In no event shall the total amounts payable
under Section 2.1(n) and this Section 2.1(o) exceed the amount that would have
been payable under Section 2.1(n) if the revenues and expenses described in this
Section 2.1(o) had been included in Earn-Out Period EBITA. If PentaStar sells
all or substantially all of the assets and operations of the Partel Division
prior to a PentaStar valuation event, PentaStar shall require the purchaser to
agree to assume the obligations of PentaStar to pay any amounts that may become
due under this Section 2.1(o). In that event, the purchaser may pay such amount
in a combination of cash and such purchaser's common equity securities based on
the fair market value of such securities on the relevant dates as provided in
this Section 2.1(o).

                  (p) Resolution of Disputes. If any adjustments to the
Adjustment Financial Statements or the Earn-Out Financial Statements are
proposed by PentaStar or the Shareholders pursuant to Section 2.1(l) or 2.1(n),
PentaStar and the Shareholders will negotiate in good faith to resolve any
dispute, provided that if the dispute is not resolved within 10 days following
the receipt of the proposed adjustments then PentaStar and the Shareholders will
retain the Denver, Colorado office of BDO Seidman LLC to resolve such dispute,
which resolution will be final and binding. The fees and expenses of BDO Seidman
LLC will be paid 50% by PentaStar and 50% jointly and severally by the
Shareholders, and BDO Seidman LLC will be retained under a retention letter
executed by the parties that specifies that the determination by said firm of
any such disputes will be resolved in accordance with GAAP on a basis consistent
with the historical accounting practices of PentaStar, by choosing the position
taken in the Adjustment Financial Statements or the Earn-Out Financial
Statements, as the case may be, on the one hand, or the position of the
objecting party under Section 2.1(l) or 2.1(n), on the other hand, without
change, within 30 days of the expiration of the 20-day period described in
Section 2.1(l) or 2.1(n)(ii), as the case may be.

                  (q) Sublease. At the Closing, PentaStar, as sublessee, and
Par.com, Inc., as sublessor, shall enter into the Sublease Agreement attached
hereto as Exhibit 2.1(q) (the "Sublease"), whereunder PentaStar will sublease
from Par.com, Inc. 25% of the Premises for a period of one year after the
Closing Date. The Shareholders shall cause Par.com, Inc. to enter into the
sublease at the Closing and shall make all necessary arrangements with the owner
of the Premises to have the Premises Lease assigned to Par.com, Inc.


                                     - 7 -
<PAGE>   13

                  (r) Limitation on Shares. In no event shall the number of
Shares of PentaStar Common Stock issued as part of the Purchase Price exceed 20%
of the number of shares outstanding immediately prior to the Closing Date.

         2.2. The Closing. The closing of the transactions contemplated by this
Agreement (the "Closing") shall take place at the offices of Sherman & Howard
L.L.C. at 9:00 a.m. Denver, Colorado time on March 17, 2000, or as soon
thereafter as the conditions to closing set forth in Section 6 are satisfied
(the date upon which the Closing actually occurs being referred to as the
"Closing Date"). At the Closing, (i) the Shareholders will deliver to PentaStar
the various certificates, instruments and documents referred to in Section 6.1
and (ii) PentaStar will deliver to the Shareholders the various certificates,
instruments and documents referred to in Section 6.2.

3. Representations and Warranties.

         3.1. Representations and Warranties of the Shareholders. The
Shareholders jointly and severally represent and warrant to PentaStar that the
statements contained in this Section 3.1 are correct and complete as of the date
of this Agreement and will be correct and complete as of the Closing Date (as
though made then and as though the Closing Date were then substituted for the
date of this Agreement throughout this Section 3.1).

                  (a) Organization, Good Standing, Etc. The Company is a
corporation duly organized, validly existing and in good standing under the laws
of the State of Arizona, and is not required to be qualified to do business as a
foreign corporation in any jurisdiction. The Company has all requisite corporate
power and authority to own, lease and operate its properties and to carry on its
business as now being conducted. The copies of the articles of incorporation
(certified by the Corporation Commission of the State of Arizona) and the bylaws
of the Company, both as amended to date, which have been delivered to PentaStar
by the Shareholders and are attached as Exhibits 3.1(a)(i) and 3.1(a)(ii),
respectively, are complete and correct, and the Company is not in default under
or in violation of any provision of its articles of incorporation or bylaws. The
minute books (which contain the records of all meetings of or actions by the
shareholders, the board of directors, and any committees of the board of
directors) and the stock certificate books and the stock record books of the
Company, copies of which have been delivered to PentaStar by the Shareholders,

                           (ii) Each Company Welfare Plan has been maintained
and administered in substantial compliance with its terms and with all
applicable Legal Requirements.

                           (iii) Exhibit 3.1(m)(iii) lists each employment,
severance or other similar contract, arrangement or policy and each plan or

insurance, compensation or other benefits that: (A) is not an Employee Benefit
Plan; (B) is entered into, maintained or contributed to, by the Company; and (C)

Such contracts, plans and arrangements as are described in this Section

Arrangements." Copies and descriptions (including descriptions of the number and
employment classifications of employees covered by each such Benefit
Arrangement) have been delivered by the Shareholders to PentaStar and attached
hereto as part of Exhibit 3.1(m)(iii). Each Benefit Arrangement has been

                           (iv) No Company Welfare Plan is maintained in
connection with any trust described in Section 501(c)(9) of the Code.

                           (v) There have been no prohibited transactions with
respect to any Company Welfare Plan. No "Fiduciary" (as defined in Section 3(21)
of ERISA) has any Liability for breach of fiduciary duty or any other failure to
act or comply in connection with the administration or investment of the assets
of any such Company Welfare Plan. No action, suit, proceeding, hearing or
investigation with respect to the administration or the investment of the assets
of any Company Welfare Plan (other than routine claims for benefits) is pending
or, to the best knowledge of the Shareholders is threatened. None of the
Shareholders has any knowledge of any basis for any such action, suit,
proceeding, hearing or investigation.

                           (vi) The Company does not maintain and has never
maintained nor contributes, or ever has contributed, or ever has been required
to contribute, to any Company Welfare Plan providing health or medical benefits
for current or future retired or terminated employees, their spouses or their
dependents (other than in accordance with Code Section 4980B). No condition
exists that would prevent the Company from amending or terminating any Company
Welfare Plan or Benefit Arrangement providing health or medical benefits in
respect of any active or retired employees of the Company.

health plan" (as defined in Code Section 5000(b)(l)) has been administered in
accordance with the requirements of Part 6 of Subtitle B of Title I of ERISA and
Code Section 4980B and nothing done or omitted to be done in connection with the

                           (viii) There is no contract, agreement, plan or
arrangement covering any employee or former employee of the Company that,
individually or collectively, could give rise to the payment of any amount that

the Code.

                           (ix) The Company has made, before the date of this
Agreement, all required contributions and premium payments under each Company

                  (n) Employees and Labor.

                           (i) The Company has not received any notice, nor, to
the best knowledge of the Shareholders, is there any reason to believe that any
Key Employee of the Company or any group of employees of the Company has any
plans to terminate his, her or its employment with the Company. To the best
knowledge of the Shareholders, no Key Employee is subject to any agreement,
obligation, Order or other legal hindrance that impedes or might impede such
executive or key employee from devoting his or her full business time to the
affairs of the Company prior to the Closing Date and, if such person becomes an
employee of PentaStar, to the affairs of PentaStar after the Closing Date. The
Company will not be required to give any notice under the Worker Adjustment and
Retraining Notification Act, as amended, or any similar Legal Requirement as a
result of this Agreement, the Other Seller Agreements or the transactions
contemplated hereby or thereby. Except as described on Exhibit 3.1(n)(i), the
Company does not have any labor relations problems or disputes, nor has the
Company experienced any strikes, grievances, claims of unfair labor practices or
other collective bargaining disputes. The Company is not a party to or bound by
any collective bargaining agreement, there is no union or collective bargaining
unit at the Company's facilities, and no union organization effort has been
threatened, initiated or is in progress with respect to any employees of the
Company.

                           (ii) Exhibit 3.1(n)(ii) lists (A) the name of each
salesperson (whether such salesperson was an employee or independent contractor)
of the Company who has left the employment of the Company in the twelve-month
period prior to the date of this Agreement, (B) the date such salesperson left
the employment of the Company and (C) the dollar amount of orders booked by the
Company during the twelve-month period prior to the date such salesperson left
the employment of the Company which were attributable to such salesperson or for
which such salesperson was responsible.

                  (o) Customer and Service Provider Relationships. Exhibit
3.1(o)(i)(A) lists each customer that individually or with its affiliates was,
based on the Company's revenues during the fiscal year ended December 31, 1999,
one of the Company's ten largest customers during such fiscal year or accounted
for 2% or more of the Company's revenues during such fiscal year (the "Principal
Customers").


                                     - 17 -
<PAGE>   23

Exhibit 3.1(o)(i)(B) lists each Person who is a service provider to the
Company's customers as of the date of this Agreement (the "Principal
Providers"). The Company has good commercial working relationships with its
Principal Customers and Principal Providers and since December 31, 1999, no
Principal Customer or Principal Provider has cancelled or otherwise terminated
its relationship with the Company, materially decreased its purchases from or
services supplied to the Company's customers, or, to the knowledge of the
Shareholders, threatened to take any such action. The Shareholders have no basis
to anticipate any problems with the Company's relationships with its Principal
Customers or Principal Service Providers. To the best knowledge of the
Shareholders, no Principal Customer or Principal Provider has any plans to
terminate their relationship with the Company and the execution and delivery of
this Agreement and the consummation of the transactions contemplated hereby will
not adversely affect the relationship of the Company with any Principal Customer
or Principal Provider prior to the Closing Date or of PentaStar with any
Principal Customer or Principal Provider after the Closing Date.

                  (p) Environmental Matters. The Company is conducting and at
all times has conducted its business and operations, and has occupied, used and
operated the Premises and all other real property and facilities presently or
previously owned, occupied, used or operated by the Company, in compliance with
all Environmental Obligations and so as not to give rise to Liability under any
Environmental Obligations or to any impact on the Company's business or
activities. To the best knowledge of the Shareholders, the Company has no
Liability under any Environmental Obligation, nor is there any basis for any
such Liability.

                  (q) Intellectual Property. The Company owns or has the legal
right to use each item of Intellectual Property required to be identified on
Exhibit 3.1(h). To the best knowledge of the Shareholders, (i) the continued
operation of the business of the Company as currently conducted will not
interfere with, infringe upon, misappropriate or conflict with any Intellectual
Property rights of another Person and (ii) no other Person has interfered with,
infringed upon, misappropriated or otherwise come into conflict with any
Intellectual Property rights of the Company or any Intellectual Property
included in the Acquired Assets. Neither the Company nor, to the best knowledge
of the Shareholders, any owner of any Intellectual Property included in the
Acquired Assets has granted any license, sublicense or permission with respect
to any Intellectual Property owned or used in the Company's business. No claims
are pending or, to the knowledge of the Shareholders, threatened, that the
Company is infringing or otherwise adversely affecting the rights of any Person
with regard to any Intellectual Property. To the best knowledge of the
Shareholders, all of the Intellectual Property that is owned by the Company and
is included in the Acquired Assets is owned free and clear of all Encumbrances
and was not misappropriated from any Person, and all portions of the
Intellectual Property that are licensed by the Company are licensed pursuant to
valid and existing license agreements. The consummation of the transactions
contemplated by this Agreement will not result in the loss or material
diminution of any Intellectual Property or rights in Intellectual Property.

                  (r) Year 2000 Warranty. To the best knowledge of the
Shareholders, the computer software owned by the Company and all other
Intellectual Property used or held for use by the Company in its business
accurately processes date/time data (including calculating, comparing, and
sequencing) from, into, and between the twentieth and twenty-first centuries,
and the years 1999 and 2000 and leap year calculations and the date September 9,
1999 when either (i) used as a standalone application, or (ii) integrated into
or otherwise used in conjunction with the third party hardware, software,
firmware and data over which the Shareholders and the Company have no control
("Third Party Products") with which such Company software or other Intellectual
Property was designated or intended to operate at the time such Company software
was (i) developed or (ii) first provided to the Company's customers, or tested
by the Company for


                                     - 18 -
<PAGE>   24

such customers, whichever is later. Notwithstanding the foregoing, the Company
shall not be considered to be in breach of the representation and warranty in
the immediately preceding sentence if the failure of such Company software to
comply with such representation and warranty is attributable solely to (x) a
failure by any Third Party Product to accurately process date/time data
(including but not limited to, calculating, comparing, and sequencing) from,
into, and between the twentieth and twenty-first centuries, and the years 1999
and 2000 and leap year calculations and the date September 9, 1999; or (y) any
modification of the Company software by any party other than the Company (unless
such modification was made at the direction of the Company).

                  (s) Brokers' Fees. Except as set forth on Exhibit 3.1(s), the
Company does not have, and will not have as a result of the consummation of this
Agreement, any Liability to pay any fees or commissions to any broker, finder or
agent with respect to the transactions contemplated by this Agreement.

                  (t) Guaranties. The Company is not a guarantor or otherwise
liable for any Liability (including indebtedness for borrowed money) of any
other Person. Except as set forth on Exhibit 3.1(t), no Person is a guarantor or
otherwise liable for any Liability (including indebtedness for borrowed money)
of the Company.

                  (u) Disclosure. None of the documents or information provided
to PentaStar by the Company, any Shareholder or any agent or employee thereof in
the course of PentaStar's due diligence investigation and the negotiation of
this Agreement and Sections 3.1 and 3.2 of this Agreement and the disclosure
Exhibits referred to therein, including the financial statements referred to
above in Section 3.1, contains any untrue statement of any material fact or omit
to state a material fact necessary in order to make the statements contained
herein or therein not misleading. There is no fact which materially adversely
affects the business, condition, affairs or operations of the Company or any of
its properties or assets which has not been set forth in this Agreement or such
Exhibits, including such financial statements.

                  Nothing in the disclosure Exhibits referred to in Section 3.1
shall be deemed adequate to disclose an exception to a representation or
warranty made herein unless the applicable disclosure Exhibit identifies the
exception with particularity and describes the relevant facts in reasonable
detail. Without limiting the generality of the foregoing, the mere listing (or
inclusion of a copy) of a document or other item shall not be deemed adequate to
disclose an exception to a representation or warranty made herein (unless the
representation or warranty has to do with the existence of the document or other
item itself). The Shareholders acknowledge and agree that the fact that they
have made disclosures pursuant to Section 3.1 or 3.2 or otherwise of matters, or
did not have knowledge of matters, which result in Adverse Consequences to
PentaStar shall not relieve the Shareholders of their obligation pursuant to
Section 7 of this Agreement to indemnify and hold PentaStar harmless from all
Adverse Consequences.

         3.2. Representations, Warranties and Agreements of Each Shareholder.

                  (a) Investment Representations. Each Shareholder, severally

Agreement, each of the parties will take such further action (including the
execution and delivery of such further instruments and documents) as any other
party reasonably may request, all at the sole cost and expense of the requesting
party (unless the requesting party is entitled to indemnification therefor under
Section 7).

         5.2. Transition. No Shareholder will take any action at any time that
is designed or intended to have the effect of discouraging any customer,
supplier, lessor, licensor or other business associate of the Company in the
Retained Operations from establishing or continuing a business relationship with
PentaStar after the Closing.

         5.3. Cooperation. In the event and for so long as any party actively is
contesting or defending against any action, suit, proceeding, hearing,
investigation, charge, complaint, claim or demand in connection with (a) any
transaction contemplated by this Agreement or (b) any fact, situation,
circumstance, status, condition, activity, practice, plan, occurrence, event,
incident, action, failure to act or transaction on or prior to the Closing
involving any of the Acquired Assets or the Company's business, each of the
other parties will cooperate with such party and its counsel in the contest or
defense, make available their personnel, and provide such testimony as shall be
reasonably necessary in connection with the contest or defense, all at the sole
cost and expense of the contesting or defending party (unless the contesting or
defending party is entitled to indemnification therefor under Section 7).

         5.4. Confidentiality. The Shareholders will treat and hold as
confidential all Confidential Information concerning PentaStar, the Company's
business or the Acquired Assets, refrain from using any such Confidential
Information and deliver promptly to PentaStar or destroy, at the request and
option of PentaStar, all of such Confidential Information in its or their
possession. PentaStar will treat and hold as confidential all Confidential
Information concerning the Excluded Operations, refrain from using any such
Confidential Information and deliver promptly to the Shareholders or destroy, at
the request and option of the Shareholders, all of such Confidential Information
in its or their possession.

         5.5. Post-Closing Announcements. Following the Closing, no Shareholder
will issue any press release or make any public announcement relating to the
subject matter of this Agreement without the prior written approval of
PentaStar.

         5.6. Financial Statements. The Shareholders will, upon request of
PentaStar, cooperate with PentaStar and render such assistance to PentaStar and
its accountants as may be required to produce such historical and on-going
financial statements and audits as PentaStar may request, including, without


                                     - 24 -

limitation, signing management representation letters reasonably requested by
PentaStar's auditors, all at the sole cost and expense of PentaStar, but without
additional consideration to the Shareholders. The Shareholders acknowledge that
PentaStar may be required by applicable law to include audited financial
statements with respect to the business of the Company in reports filed with
governmental agencies and that the inability to audit the financial statements
as of the Closing Date promptly after the Closing could have a material adverse
effect on PentaStar.

         5.7. Satisfaction of Liabilities.

                  (a) Following the Closing, the Shareholders will pay promptly
when due any Excluded Liabilities not previously paid and any Taxes attributable
to the transactions contemplated by this Agreement.

                  (b) The Shareholders, at their expense, promptly will take or
cause to be taken any action necessary to remedy any failure of the Premises or
the acquired business to comply at the Closing Date with any Legal Requirement,
upon receipt of notice from PentaStar at any time.

                  (c) PentaStar will pay and perform, as and when due (except to
the extent the validity thereof or the liability therefor is being contested by
PentaStar), the Retained Liabilities.

         5.8. Termination of Obligations. Effective as of the Closing Date,
PentaStar shall not have any Liability to any Shareholder or any relative or
affiliate thereof or of the Company, except as otherwise provided in this
Agreement or in an Other Seller Agreement or in any other written agreement
entered into on or after the Closing Date. Effective as of the Closing Date, the
Shareholders shall not have any Liability to PentaStar, except as otherwise
provided in this Agreement, in an Other Seller Agreement or in any other written
agreement entered into on or after the Closing Date.

         5.9. Transfer Restrictions. Unless otherwise agreed by PentaStar,
except for transfers by a Shareholder to (a) immediate family members of such
Shareholder who agree to be bound by the restrictions set forth in this Section
5.9 (and a copy of such agreement is furnished to PentaStar prior to the
transfer), (b) trusts, limited partnerships or other estate planning entities
for the benefit of such Shareholder or family members of such Shareholder, the
trustees, partners or other persons having authority to bind the trust, limited
partnership or other estate planning entity of which agree to be bound by such
restrictions (and a copy of such agreement is furnished to PentaStar prior to
the transfer), or (c) any charitable organization that qualifies for receipt of
charitable contributions under Section 170(c) of the Code and such organization
agrees to be bound by such restrictions (and a copy of such agreement is
furnished to PentaStar prior to the transfer), each Shareholder agrees that such
Shareholder will not sell, assign, exchange, transfer, pledge or otherwise
dispose of at any time prior to the date which is 18 months after the Closing
any of the PentaStar Shares received by such Shareholder as part of the Purchase
Price. Thereafter, up to 33.33% of the PentaStar Shares received as part of the
Purchase Price by such Shareholder may be resold at any time, and an additional
16.67% of the PentaStar Shares received as part of the Purchase Price by the
Shareholder may be resold by the Shareholder beginning 24 months after the
Closing. Any remaining PentaStar Shares may not be sold until the earlier to
occur of (x) sale of all or substantially all of the assets or outstanding
shares of PentaStar, whether by way of merger, acquisition or other method
(except a merger or consolidation immediately after which the Persons who were
shareholders of PentaStar before the transaction own a majority of the
outstanding equity securities of the surviving or resulting entity) or (y)
October 26, 2004. Certificates for the PentaStar Shares delivered to the
Shareholder pursuant to the Agreement will bear a legend substantially in the
form set forth below as long as applicable:


                                     - 25 -

THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO THAT CERTAIN AGREEMENT
AND PLAN OF MERGER DATED AS OF JANUARY 1, 2000 (THE "AGREEMENT"), BY AND AMONG
THE ISSUER, THE SHAREHOLDERS OF PARTEL, INC. AND PARTEL, INC. PRIOR TO THE
EXPIRATION OF THE HOLDING PERIOD SET FORTH IN THE AGREEMENT, SUCH SHARES MAY NOT
BE SOLD, ASSIGNED, EXCHANGED, TRANSFERRED, PLEDGED OR OTHERWISE DISPOSED OF
WITHOUT THE WRITTEN CONSENT OF THE ISSUER, AND THE ISSUER SHALL NOT BE REQUIRED
TO GIVE EFFECT TO ANY ATTEMPTED SALE, ASSIGNMENT, EXCHANGE, TRANSFER, PLEDGE OR
OTHER DISPOSITION WHICH VIOLATES THE AGREEMENT. UPON THE WRITTEN REQUEST OF THE
HOLDER OF THIS CERTIFICATE, THE ISSUER AGREES TO REMOVE THIS RESTRICTIVE LEGEND
(AND ANY STOP ORDER RELATING TO THIS RESTRICTIVE LEGEND PLACED WITH THE TRANSFER
AGENT) WHEN THE APPLICABLE HOLDING PERIOD HAS EXPIRED.

         PentaStar shall issue separate certificates to the Shareholder
representing the shares of PentaStar Shares subject to each of the three periods
of restriction contemplated by this Section 5.9.

         The restrictions set forth along in this Section 5.9 shall be in
addition to any restrictions on transfer imposed by the Securities Act and
applicable state securities laws set forth in Section 3.2 and otherwise required
by law. Each Shareholder also agrees to comply with such restrictions.

         5.10. Collection of Excluded Receivables. The Excluded Assets include
all payments received by the Company or PentaStar on or after the Effective Date
in respect of Effective Date Orders, to the extent and only to the extent that
the total amount of such payments received by the Company or PentaStar on or
after the Effective Date exceeds $750,000 (such excess, the "Excluded
Receivables"). From and after the Closing Date, PentaStar shall continue to bill
and collect the Excluded Receivables on behalf of the Shareholders in accordance
with its normal billing and collection practices, but shall not be required to
institute any suit or other proceeding to collect any Excluded Receivables.
PentaStar shall have no liability to the Shareholders if any Excluded Receivable
is not collected. Upon receipt of any payment in respect of an Excluded
Receivable, PentaStar shall pay, on behalf of the Shareholders, any commission
due from such payment and shall remit to the Shareholders' Agent 80% of the
amount remaining after such commission is paid. The other 20% shall be retained
by PentaStar as a fee for the billing and collection services provided under
this Section 5.10. Payments to the Shareholders hereunder shall be made within
60 days after the end of each calendar quarter in respect of payments received
during the quarter and shall be accompanied by a written calculation of the
amount due to the Shareholders. PentaStar shall be entitled to be reimbursed for
any costs it incurs in collecting any Excluded Receivables or in fulfilling any
condition to the right to receive payment of any Excluded Receivable and may
offset such costs against any amount owing to the Shareholders.

         5.11. Tax Returns. The Shareholders shall be responsible for the timely
filing of the Company's tax returns for the 1999 tax year and the short tax year
from the Effective Date through the Closing Date and for the timely payment of
all income or other taxes relating to those periods. PentaStar will make the
books and records of the Company available to the Shareholders as required for
the preparation of such returns or for any subsequent audit or examination of
any tax return of the Company for any period ending with or prior to the Closing
Date. PentaStar shall notify the Shareholders' Agent of any inquiry, audit or
examination of which PentaStar receives notice relating to the Company's tax
returns for any period ending with or prior to the Closing Date and the
Shareholders' Agent shall have the right to control the defense and settlement
of


                                     - 26 -
<PAGE>   32
any such inquiry, audit or examination. PentaStar shall not file any amended
return for the Company for any period ending with or prior to the Closing Date
without the consent of the Shareholders' Agent, unless required to do so by
applicable law. The Shareholders shall afford PentaStar a reasonable opportunity
to review any new or amended tax return for the Company filed by them hereunder
and shall not make any election or take any other action on any such return that
would increase the tax liability of the Company for periods after the Closing
Date.

         5.12. Defense of Litigation. The pending litigation disclosed on
Exhibit 3.1(i)(i) is included in the Excluded Liabilities. In addition to paying
any liability that may be incurred in those suits, the Shareholders shall
conduct the defense of those suits and pay all of the costs of the defense.
PentaStar shall cooperate with the Shareholders in defending those suits in such
reasonable respects as the Shareholders may request, but the Shareholders shall
reimburse PentaStar for all expenses incurred in connection therewith.

7. Remedies for Breaches of This Agreement.

         7.1. Indemnification Provisions for Benefit of PentaStar.

                  (a If any Shareholder breaches (or if any Person other than
PentaStar alleges facts that, if true, would mean any Shareholder has breached)
any of the representations or warranties of any Shareholder contained herein and
PentaStar gives notice thereof to the Shareholders' Agent within the Survival
Period, or if any Shareholder breaches (or if any Person other than PentaStar
alleges facts that, if true, would mean any Shareholder has breached) any
covenants of any Shareholder contained herein or any representations, warranties
or covenants of any Shareholder contained in any Other Seller Agreement and
PentaStar gives notice thereof to the Shareholders' Agent, then the Shareholders
agree to jointly and severally (except that each Shareholder's Liability with
respect to Section 3.2 only shall be several and not joint) indemnify and hold
harmless PentaStar from and against any Adverse Consequences PentaStar may
suffer resulting from, arising out of, relating to or caused by any of the
foregoing regardless of whether the Adverse Consequences are suffered during or
after the Survival Period. In determining whether there has been a breach of any
representation or warranty contained in Section 3.1 or 3.2 and in determining
for purposes of the preceding sentence the amount of Adverse Consequences
suffered by PentaStar, such representations and warranties shall not be
qualified (other than by the reference to "knowledge" set forth in the last
sentence of Section 3.1(o)) by "material," "materiality," "in all material
respects," "best knowledge," "best of knowledge" or "knowledge" or words of
similar import, or by any phrase using any such terms or words. The Shareholders
also agree to jointly and severally indemnify and hold harmless PentaStar from
and against any Adverse Consequences PentaStar may suffer which result from,
arise out of, relate to or are caused by (i) any Liability of the Company or any
Shareholder not included in the Retained Liabilities or (ii) any condition,
circumstance or activity existing prior to the Closing Date which relates to any
Legal Requirement or any act or omission of the Company or any Shareholder or
any predecessor with respect to, or any event or circumstance related to, the
Company's, any Shareholder's or any predecessor's ownership, use or operation of
any of the Acquired Assets, the Excluded Assets, the Premises or any other
assets or properties or the conduct of its or their business, regardless, in the
case of (i) or (ii), of (A) whether or not such Liability, act, omission, event,
circumstance or matter was known or disclosed to PentaStar, was disclosed on any
Exhibit hereto or is a matter with respect to which any Shareholder did or did
not have knowledge, (B) when such Liability, act, omission, event, circumstance
or matter occurred, existed, occurs or exists (provided that the obligation of
the Shareholders to indemnify against Adverse Consequences arising from the
ownership, use or operation of the Excluded Assets shall apply only to such
ownership, use or operation prior to the Closing Date, including any failure
after the Closing Date to perform any obligation or commitment entered into
prior to the Closing Date) and (C) whether a claim with respect thereto was
asserted before or is asserted after the Closing Date. If any dispute arises
concerning whether any indemnification is owing which cannot be resolved by
negotiation among the parties within 30 days of notice of claim for
indemnification from the party claiming indemnification to the party against
whom such claim is asserted, the dispute will be resolved by arbitration
pursuant to this Agreement; provided, however, that if PentaStar is sued in an
action relating in whole or in part to a claim against which it is or may be
entitled to indemnification hereunder, it may, at its option, join the
Shareholders in that action and have its right to indemnification adjudicated by
the court.

                  (b Amounts needed to cover any indemnification claims by
PentaStar against any Shareholder during the Escrow Period may be taken by
PentaStar out of the Escrow Deposit. At the end of the Escrow Period, amounts of
the Escrow Deposit which may reasonably be needed to cover pending
indemnification claims made by PentaStar (such amounts to be determined by
PentaStar based upon the good


                                     - 30 -
<PAGE>   36

faith exercise of its business judgment) shall be retained in the Escrow Account
until such claims are resolved, and any excess amount of the Escrow Deposit
shall be paid to the Shareholders. For purposes of indemnification claims, each
of the shares of PentaStar Common Stock shall be valued at its Fair Market Value
as of the date that it is delivered from the Escrow Account. PentaStar and the
Shareholders' Agent shall jointly give instructions to the Escrow Agent to carry
out the intent of this Section 7.1(b). Any disputes concerning the escrowed
property shall be settled by arbitration as provided in this Agreement.
PentaStar, on the one hand, and the Shareholders jointly and severally, on the
other hand, shall each be responsible for one-half of the fees, charges and
expenses payable to the Escrow Agent pursuant to the Escrow Agreement. Nothing
in this Section 7.1(b) shall be construed to limit PentaStar's right to
indemnification to amounts on deposit in the Escrow Account or to require that
the Escrow Account first be exhausted before PentaStar may resort to any other
remedy available under this Agreement or otherwise. The Shareholders shall have
joint and several Liability for all amounts needed to cover indemnification
claims, which amounts shall be paid directly to PentaStar.

                  (c During the time that any PentaStar Shares are held in the
Escrow Deposit, the Shareholder who deposited such shares shall have the right
to vote such shares and shall have the economic benefit of any dividends paid on
such shares. All such dividends shall be retained in the Escrow Deposit and
shall be available for the payment of indemnification claims under Section
7.1(b). In the event that PentaStar proposes to take any shares from the Escrow
Deposit to satisfy an indemnification claim, the Shareholders shall have the
right, in their sole discretion, to pay to the Escrow Agent an amount of cash
equal to the Fair Market Value of the shares proposed to be taken, determined as
of the date such payment is made, and receive from the Escrow Agent certificates
representing such shares. If the Shareholders exercise that right, PentaStar and
the Shareholders' Agent shall execute joint written instructions to the Escrow
Agent to deliver the cash so paid to PentaStar and to transfer the appropriate
number of shares of PentaStar Common Stock to the Shareholders. If the
Shareholders do not exercise that right, PentaStar may nonetheless require the
Shareholders to substitute cash for the shares to be taken from the Escrow
Deposit if, in the good faith opinion of PentaStar, based on advice of counsel,
the taking of shares from the Escrow Deposit would cause the Purchase Price,
taken as a whole, not to comply with the continuity of interest test for a
tax-free reorganization under Section 368 of the Code. For that purpose, the
parties agree that, under current law, such continuity of interest test would
not require that the PentaStar Shares constitute more than half of the total
Purchase Price, after all adjustments, and taking into account the distribution
of the Excluded Assets, the assumption of the Excluded Liabilities and any
re-acquisition by PentaStar of any of the PentaStar Shares.

                  (d Notwithstanding any other provision of this Agreement, the
Shareholders shall not be liable for any tax assessed as a result of PentaStar
transactions occurring on or after the Closing Date or for any failure by
PentaStar to publish notice of the Merger or file an affidavit of such
publication as required by Arizona law.

                                     - 31 -

         7.2. Indemnification Provisions for Benefit of the Shareholders. If
PentaStar breaches (or if any Person other than a Shareholder alleges facts
that, if true, would mean PentaStar has breached) any of its representations or
warranties contained herein and the Shareholders' Agent gives notice of a claim
for indemnification against PentaStar within the Survival Period, or if
PentaStar breaches (or if any Person other than a Shareholder alleges facts
that, if true, would mean PentaStar has breached) any of its covenants contained
herein or any of its representations, warranties or covenants contained in any
Other PentaStar Agreement and the Shareholders' Agent gives notice thereof to
PentaStar, then PentaStar agrees to indemnify and hold harmless the Shareholders
from and against any Adverse Consequences the Shareholders may suffer which
result from, arise out of, relate to, or are caused by the breach or alleged
breach, regardless of whether the Adverse Consequences are suffered during or
after the Survival Period. In determining whether there has been a breach of any
representation or warranty contained in Section 3.3 and in determining the
amount of Adverse Consequences suffered by the Shareholders for purposes of this
Section 7.2, such representations and warranties shall not be qualified by
"material," "materiality," "in all material respects," "best knowledge," "best
of knowledge" or "knowledge" or words of similar import, or by any phrase using
any such terms or words. PentaStar also agrees to indemnify and hold harmless
the Shareholders from and against any Adverse Consequences they may suffer which
result from, arise out of, relate to or are caused by (i) any of the Retained
Liabilities or (ii) any act or omission of PentaStar with respect to, or any
event or circumstance related to, PentaStar's ownership, use or operation of the
Acquired Assets or the conduct of the Retained Operations after the Closing
Date; provided, however, that such Adverse Consequences shall not include any
decline in value of the PentaStar Shares, any failure to achieve all or any
portion of an Earn-Out Amount that the Shareholders may anticipate at the time
this Agreement is entered into or any failure by any Shareholder to earn any
bonus or other compensation under any employment arrangement with PentaStar. If
any dispute arises concerning whether any indemnification is owing which cannot
be resolved by negotiation among the parties within 30 days of notice of claim
for indemnification from the party claiming indemnification to the party against
whom such claim is asserted, the dispute will be resolved by arbitration
pursuant to this Agreement; provided, however, that any Shareholder is sued in
an action relating in whole or in part to a claim against which he or she is or
may be entitled to indemnification hereunder, he or she may, at its option, join
PentaStar in that action and have his or her right to indemnification
adjudicated by the court.

         7.3. Matters Involving Third Parties.

                  (a If any Person not a party to this Agreement (including,
without limitation, any Governmental Authority) notifies any party (the
"Indemnified Party") with respect to any matter (a "Third Party Claim") which
may give rise to a claim for indemnification against any other party (the
"Indemnifying Party"), then the Indemnified Party will notify each Indemnifying
Party thereof in writing within 15 days after receiving such notice. No delay on
the part of the Indemnified Party in notifying any Indemnifying Party will
relieve the Indemnifying Party from any obligation hereunder unless (and then
solely to the extent) the Indemnifying Party thereby is prejudiced.

                  (b Any Indemnifying Party will have the right, at its sole
cost and expense, to defend the Indemnified Party against the Third Party Claim
with counsel of its choice satisfactory to the Indemnified Party so long as (i)
the Indemnifying Party notifies the Indemnified Party in writing within 10 days
after the Indemnified Party has given notice of the Third Party Claim that the
Indemnifying Party will indemnify the Indemnified Party from and against the
entirety of any Adverse Consequences the Indemnified Party may suffer resulting
from, arising out of, relating to or caused by the Third Party Claim, (ii) the
Indemnifying Party provides the Indemnified Party with evidence reasonably
acceptable to the Indemnified Party that the


                                     - 32 -
<PAGE>   38

Indemnifying Party will have the financial resources to defend against the Third
Party Claim and fulfill its indemnification obligations hereunder, (iii) the
Third Party Claim involves only money damages and does not seek an injunction or
other equitable relief, (iv) settlement of, or an adverse judgment with respect
to, the Third Party Claim is not, in the good faith judgment of the Indemnified
Party, likely to establish a precedential custom or practice materially adverse
to the continuing business interests of the Indemnified Party, and (v) the
Indemnifying Party conducts the defense of the Third Party Claim actively and
diligently. If the Indemnifying Party does not assume control of the defense or
settlement of any Third Party Claim in the manner described above, it will be
bound by the results obtained by the Indemnified Party with respect to the Third
Party Claim.

                  (c So long as the Indemnifying Party is conducting the defense
of the Third Party Claim in accordance with Section 7.3(b) above, (i) the
Indemnified Party may retain separate co-counsel at its sole cost and expense
and participate in the defense of the Third Party Claim, (ii) the Indemnified
Party will not consent to the entry of any judgment or enter into any settlement
with respect to the Third Party Claim without the prior written consent of the
Indemnifying Party (not to be withheld unreasonably), and (iii) the Indemnifying
Party will not consent to the entry of any judgment or enter into any settlement
with respect to the Third Party Claim without the prior written consent of the
Indemnified Party (not to be withheld unreasonably).

                  (d In the event any of the conditions in Section 7.3(b) above
is or becomes unsatisfied, however, (i) the Indemnified Party may defend

Colorado or any other jurisdiction) that would cause the application of the laws

         9.10. Expenses. Except as otherwise provided in Section 8.2 (a)
PentaStar shall bear its own costs and expenses (including, without limitation,

         9.11. Arbitration. Except as provided in Sections 7.1(a) and 7.2(a),
any disputes arising under or in connection with this Agreement, including,
without limitation, those involving claims for specific performance or other
equitable relief, will be submitted to binding arbitration in Denver, Colorado
before the Judicial Arbiter Group, but under the Commercial Arbitration Rules of
the American Arbitration Association under the authority of federal and state
arbitration statutes, and shall not be the subject of litigation in any forum.
If the Judicial Arbiter Group is unavailable to conduct the arbitration, then it
shall be before another arbitral body in Denver, Colorado selected by PentaStar
and the Shareholders' Agent or, if they cannot agree on another arbitral body,
the American Arbitration Association. EACH PARTY, BY SIGNING THIS AGREEMENT,
VOLUNTARILY, KNOWINGLY AND INTELLIGENTLY WAIVES ANY RIGHTS SUCH PARTY MAY
OTHERWISE HAVE TO SEEK REMEDIES IN COURT OR OTHER FORUMS, INCLUDING THE RIGHT TO
JURY TRIAL. The arbitrator shall have full authority to order specific
performance and other equitable relief and award damages and other relief
available under this Agreement or applicable law, but shall have no authority to
add to, detract from, change or amend the terms of this Agreement or existing
law. All arbitration proceedings, including settlements and awards, shall be
confidential. The decision of the arbitrators will be final and binding, and
judgment on the award by the arbitrators may be entered in any court of
competent jurisdiction. THIS SUBMISSION AND AGREEMENT TO ARBITRATE WILL BE
SPECIFICALLY ENFORCEABLE. The prevailing party or parties in any such
arbitration or in any action to enforce this Agreement will be entitled to
recover, in addition to any other relief awarded by the arbitrator, all
reasonable costs and expenses, including fees and expenses of the arbitrators
and attorneys, incurred in connection therewith. If each party prevails on
specific issues in the arbitration or action, the arbitrator or court may
allocate the costs incurred by all parties on a basis it deems appropriate.

         9.12. Construction. The parties have participated jointly in the
negotiation and drafting of this Agreement. In the event an ambiguity or
question of intent or interpretation arises, this Agreement will be construed as
if drafted jointly by the parties and no presumption or burden of proof will
arise favoring or


                                     - 36 -
<PAGE>   42

disfavoring any party by virtue of the authorship of any of the provisions of
this Agreement. The word "including" will mean including without limitation. The
parties intend that each representation, warranty and covenant contained herein
will have independent significance. If any party breaches any representation,
warranty or covenant contained herein in any respect, the fact that there exists
another representation, warranty or covenant relating to the same subject matter
(regardless of the relative levels of specificity) which the party has not
breached will not detract from or mitigate the fact that the party is in breach
of the first representation, warranty or covenant.

         9.13. Incorporation of Exhibits. The Exhibits identified in this
Agreement are incorporated herein by reference and made a part hereof.

         9.14. Shareholders' Agent. Each Shareholder hereby authorizes and
appoints the Shareholders' Agent as its, his or her exclusive agent and
attorney-in-fact to act on behalf of each of them with respect to all matters
which are the subject of this Agreement, including, without limitation, (a)
receiving or giving all notices, instructions, other communications, consents or
agreements that may be necessary, required or given hereunder and (b) asserting,
settling, compromising, or defending, or determining not to assert, settle,
compromise or defend, (i) any claims which any Shareholder may assert, or have
the right to assert, against PentaStar, or (ii) any claims which PentaStar may
assert, or have the right to assert, against any Shareholder. The Shareholders'
Agent hereby accepts such authorization and appointment. Upon the receipt of
written evidence satisfactory to PentaStar to the effect that the Shareholders'
Agent has been substituted as agent of the Shareholders by reason of his death,
disability or resignation, PentaStar shall be entitled to rely on such
substituted agent to the same extent as they were theretofore entitled to rely
upon the Shareholders' Agent with respect to the matters covered by this Section
9.14. No Shareholder shall act with respect to any of the matters which are the
subject of this Agreement except through the Shareholders' Agent. The
Shareholders acknowledge and agree that PentaStar may deal exclusively with the
Shareholders' Agent in respect of such matters, that the enforceability of this
Section 9.14 is material to PentaStar, and that PentaStar has relied upon the
enforceability of this Section 9.14 in entering into this Agreement.

XI.      GENERAL PROVISIONS

1.  ARBITRATION AND CHOICE OF FORUM

Any controversy or claim arising out of or relating to this contract, or the
breach thereof, shall be settled by arbitration administered by the American
Arbitration Association under its Commercial Arbitration Rules in the City of
New York, and judgment on the award rendered by the arbitrator(s) may be entered
in any court having jurisdiction thereof.

The parties acknowledge that any breach of this Agreement to arbitrate may cause
irreparable injury, and accordingly consent to the jurisdiction of the State and
Federal Courts located in the City of New York for any application to compel
specific performance of this Agreement to arbitrate.

In the event that any claim is found not to be arbitrable due to, inter alia, a
statutory policy precluding the arbitration of such claim, the parties consent
to the exclusive jurisdiction of the State and Federal Courts in the City of New
York for the adjudication of such claim.

2.  ASSIGNMENT

Agent shall not assign any right or interest under this Agreement (except for
monies due or to become due) nor delegate any activity or other obligation to be
performed or owed by Agent under this Agreement without the prior written
consent of BANSI. Agent shall advise BANSI as soon as possible if a change of
ownership of Agent is contemplated during the term of this Agreement. In the
event of an ownership change, BANSI reserves the right to terminate the existing
Agreement and at BANSI's sole discretion enter into a new Agreement with the new
ownership. Any attempted assignment or delegation in contravention of the above
shall be void and ineffective. Any assignment of monies shall be void and
ineffective to the extent that: (a) Agent shall not have given BANSI at least
thirty (30) days prior written notice of such assignment; or (b) such assignment
attempts to impose upon BANSI obligations to the assignee additional to payments
of such monies or to preclude BANSI from dealing solely and directly with Agent
in all matters pertaining to the Agreement. This Agreement may be assigned by
BANSI at any time without Agent's consent to any parent, subsidiary or affiliate
of BANSI.

3.  CHOICE OF LAW

The construction, interpretation and performance of this Agreement shall be
governed by and construed in accordance with the domestic laws of the State of

                               AMENDMENT NO. 2 TO
                       THE BELL ATLANTIC AUTHORIZED AGENT

                      NETWORK SERVICES MARKETING AGREEMENT

          This Amendment No. 2 to the Bell Atlantic Authorized Agent Network
Services Marketing Agreement ("Agreement") is made this first day of January,
1999, by and between USTeleCenters, a Delaware corporation with principal
offices located at 745 Atlantic Avenue, Boston, MA 02111-2626 (hereinafter
referred to as "Agent"), and Bell Atlantic Network Services, Inc., a Delaware
corporation with principal offices located at 1310 North Court House Road,
Arlington, Virginia 2220l (hereinafter referred to as "BANSI").

          WHEREAS, BANSI and Agent are parties to the Agreement which authorizes
Agent to act as BANSI's non-exclusive agent for the marketing of Telephone
Company Services; and

          WHEREAS, BANSI and Agent intend for Agent to serve as both a
telemarketing agent as well as a premises agent for the states of Delaware, New
Jersey, Maryland, Pennsylvania, Virginia, Washington DC, West Virginia, New
York, New Hampshire, Massachusetts, Maine, Rhode Island and Vermont
("Telemarketing Area");

NOW, THEREFORE, THE PARTIES AGREE AS FOLLOWS:

          1. In the Telemarketing Area, Agent is authorized to make sales both
          through telemarketing and customer premises visits. Unless otherwise
          authorized in writing, Agent may not telemarket outside of the
          Telemarketing Area.

          2. When Agent is acting as a telemarketer, Agent shall proactively
          contact Customers over the telephone for purposes of closing a sale
          over the phone.

          3. When Agent is acting as a telemarketer, Agent shall comply with all
          guidelines, rules and principles established by BANSI, including,
          without limitation, the following:

          (a) Agent shall have the capability and all necessary equipment to
          provide, and shall provide, in-house and remote telephone monitoring
          (as specified by BANSI) of sales and marketing calls handled by Agent.
          BANSI shall have the right to monitor any calls remotely or otherwise
          without prior written notice to Agent.

          (b) Agent shall have the necessary technology to block, and shall
          block within forty-eight (48) hours of receiving a Do Not Contact List
          from BANSI, all telephone numbers included on that list which shall
          set forth the names and/or numbers of Customers who are not to be
          contacted by Agent for the marketing and sale of Services.

          (c) As prescribed by BANSI, Agent shall tape record and verify each
          sale or, in the alternative at BANSI's discretion, Agent shall provide
          a letter of authorization from a Customer authorizing Agent to place
          an order for purchase of Services on behalf of that Customer.

          (d) Agent shall submit to BANSI, for BANSI's prior approval, all call
          scripts and guides to be used by Agent in marketing or selling the
          Services.

          (e) Agent shall limit and manage the number of contacts with potential
          or actual Customers per year or quarter as instructed by BANSI, and
          shall report detailed calling activity hereunder to BANSI upon BANSI's
          request.

          IN WITNESS WHEREOF, each party has caused this Amendment No. 2 to the
Agreement to be executed by its duly authorized representative as of the date
