Item 2.   Acquisition or Disposition of Assets

The KCS Acquisition

     On August 13, 1998 (the "Closing Date"), Allin Communications Corporation
(the "Company") acquired all of the issued and outstanding capital stock of KCS
Computer Services, Inc., a Pennsylvania corporation ("KCS"), pursuant to a Stock
Purchase Agreement (the "KCS Stock Purchase Agreement") among the Company and
the stockholders of KCS (the "KCS Stockholders").  KCS provides information
technology professional services and offers its clients a complete portfolio of
consulting and custom development services for client/server and legacy systems
on either a project solution or staff supplement basis.  KCS' client services
are generally divided into three categories: Microsoft consulting services,
information technology services and bank consulting services.  Following the
acquisition (the "KCS Acquisition"), KCS became a wholly owned subsidiary of the
Company.  The Company intends to operate KCS as a sister entity to Kent
Consulting Group, Inc., another wholly owned subsidiary of the Company, in the
Company's Allin Consulting business unit.  The following summary does not
purport to be complete and is qualified in its entirety by reference to the
documents discussed which are filed as exhibits to this report.

     The KCS Stock Purchase Agreement provides for the payment of up to $16.0
million by the Company to the KCS Stockholders, consisting of:

          (a) at the time of closing of the KCS Acquisition (collectively, the
"Initial KCS Purchase Price"), (i) $2,443,061.28 in cash, (ii) an aggregate
number of shares (the "Initial Stock Consideration") of the Company's Common
Stock, par value $.01 per share (the "Common Stock") equal to the amount
obtained by dividing $3,547,687 by $4.406 (which was the average of the bid and
asked prices of the Company's Common Stock for the thirty-day period ending
August 7, 1998 (the "Average Bid and Asked Price")), (iii) a secured promissory
note in the original principal amount of $6,200,000 (the "$6.2M Note"), such
note bearing interest at the rate of 5% per annum, with $3,000,000 of the
principal being due and payable upon the earlier to occur of (a) the sale of a
wholly-owned subsidiary of the Company or the sale of substantially all of the
operating assets of such a subsidiary, and (b) December 31, 1998, and the other
$3,200,000 of the principal being due and payable upon the earlier to occur of
(x) the receipt of financing from a third party lender sufficient to refinance
the $3,200,000 portion of such promissory note, and (b) December 31, 1998, (iv)
a second secured promissory note in the original principal amount of $2,000,000
(the "$2M Note", and together with the $6.2M Note, the "Notes"), such $2M Note
bearing interest at the rate of 6% per annum and being due and payable in full
on the second anniversary of the Closing Date, and (v) the post-closing payment
by or on behalf of KCS of a $209,252 tax liability of KCS;

          (b)  up to $1.6 million in contingent payments, consisting of (i) a
maximum of $1,200,000 in cash and (ii) a maximum of $400,000 in shares of the
Company's Common Stock (the "Contingent
<PAGE>
 
Stock Consideration").  The amount of the contingent Earn-Out Payment (the
"Earn-Out Payment") will be determined on the basis of the Adjusted Operating
Profit (as defined) of KCS for the period beginning January 1, 1998 and ending
December 31, 1998 (the "Earn-Out Period").  If Adjusted Operating Profit for the
Earn-Out Period is at least $1,671,681, the KCS Shareholders will receive an
aggregate Earn-Out Payment equal to $4.67 for each dollar by which Adjusted
Operating Profit exceeds $1,671,681, with 75% of the Earn-Out Payment being made
in cash and 25% of the Earn-Out Payment being made in shares of the Company's
Common Stock, up to a maximum of $1.2 million in cash and $400,000 in shares of
the Company's Common Stock.  The number of shares of the Company's Common Stock
to be issued will be determined by dividing (i) a sum equal to 25% of the Earn-
Out Payment by (ii) the Average Bid and Asked Price.

     Only two KCS Shareholders, James S. Kelly, Jr. and Ronald J. Pearce,
received the Initial Stock Consideration and will receive the Contingent Stock
Consideration, if any.  The other two KCS Shareholders received or will receive
all cash.  James S. Kelly, Jr. is the sole recipient of the Notes.

     If the Company does not repay the $2M Note on or before the second
anniversary of the Closing Date, the $2M Note will automatically convert into
the number of shares of Common Stock equal to (a) the amount obtained by
dividing the then outstanding indebtedness evidenced by the $2M Note by the
Average Bid and Asked Price of $4.406, or (b) at the holder's option, the amount
obtained by dividing the then outstanding indebtedness evidenced by the $2M Note
by the average of the bid and asked prices of the Company's Common Stock for the
30 days preceding the second anniversary of the Closing Date, subject to a $2.00
minimum per share price (the "Maturity Formula").  The interest on the $2M Note
is to be paid in cash, subject to approval by any then senior lender to the
Company.  In the event of any default, including a payment default with respect
to interest, the holder of the $2M Note has the following options: (i) to take
no action, (ii) to accelerate the principal amount of the $2M Note and convert
such principal amount into Common Stock in accordance with the Maturity Formula
and seek payment from the Company of accrued and unpaid interest, if any,
through the date of conversion or (iii) to accelerate the principal amount of
the $2M Note and convert such principal amount as well as accrued and unpaid
interest through the date of conversion, if any, into Common Stock in accordance
with the Maturity Formula. In addition, if there is a payment default with
respect to interest payments, the holder may also elect to accelerate the
principal amount of the $2M Note and convert such principal amount into Common
Stock in accordance with the Maturity Formula and continue to receive quarterly
payments of interest until the Maturity Date as if the principal amount of the
$2M Note remained outstanding. It will not be a payment default if the Company's
then senior lender does not permit the payment of interest on the $2M Note.
However, no indebtedness evidenced by the $2M Note will be convertible into
Common Stock unless and until the holders of the Common Stock approve the
issuance of the Common Stock upon such conversion.

                                      -2-

     For purposes of the KCS Stock Purchase Agreement, the term "Adjusted
Operating Profit" means:

          (a) the net profit of KCS, determined on an accrual basis in
accordance with generally accepted accounting principles consistently applied,
before interest income or expense, loss or gain on the sale of assets, any prior
period adjustments and income taxes; plus

          (b) expenses related to the following items incurred from January 1,
1998 through the Closing Date:

              (i)   salary, wage taxes, benefits and other expenses associated
     with the employment of James S. Kelly, Jr., not to exceed $30,500 per
     month;

              (ii)  salaries, wage taxes and benefits associated with the
     elimination of the positions of administrative office manager and
     administrative support person which are not filled prior to December 31,
     1998, not to exceed $7,200 per month; and

              (iii) professional fees for investment bankers, attorneys and
     outside accountants incurred by KCS prior to June 19, 1998 in connection
     with the anticipated sale of the KCS Stock.

     James S. Kelly, Jr. and Ronald J. Pearce will have demand registration
rights (on no more than two occasions) and unlimited piggyback registration
rights with respect to the shares of the Company's Common Stock issued to them
as (a) the Initial Stock Consideration, and (b) Contingent Stock Consideration
(if any).

     As of the Closing Date, KCS had outstanding indebtedness to a financial
institution in the amount of $626,875.  Such indebtedness was repaid on the
Closing Date, which amount was in addition to the aggregate $14.4 million
Initial KCS Purchase Price and the aggregate $1.6 million Earn-Out Payment 
described above.

     At the closing of the KCS Acquisition, James S. Kelly, Jr., Ronald J.
Pearce, Joseph J. Kelly and Bradley C. Friedel, who are all of the KCS
Shareholders, received payments in the following amounts:

Additional Financing for the KCS Acquisition

     In connection with the KCS Acquisition, the Company sold 2,750 shares of a
newly designated series of preferred stock, Series B Redeemable Preferred Stock
(the "Series B Preferred Stock"), and related warrants (the "Warrants") to
purchase shares of Common Stock, at a purchase price of $1,000 per share of
Series B Preferred Stock, resulting in proceeds to the Company of $2,750,000
which were used to pay the cash portion of the Initial KCS Purchase Price.
Additional funds of approximately $323,000 from cash on hand were required for
the transaction.  A description of the terms of the Series B Preferred Stock
follows under Item 5. - Other Information.  Purchasers of the Series B Preferred
Stock received Warrants to purchase an aggregate of 647,059 shares of Common
Stock, which is the number of shares of Common Stock equal to the product of the
number of shares of Series B Preferred Stock purchased multiplied by 1,000,
divided by $4.25, the closing price of the Common Stock as reported by The
Nasdaq Stock Market ("Nasdaq") on the last trading day preceding the Closing
Date.  The per share exercise price under the Warrants will be $4.25.  Payment
of the exercise price may be made by delivery to the Company of shares of Series
A Convertible Redeemable Preferred Stock of the Company having an aggregate
liquidation value plus accrued and unpaid dividends, if any, equal to the
exercise price for the number of shares to be purchased upon exercise.  The
Warrants will expire on the earlier to occur of (a) December 31, 1998 if the
Company is required to redeem the outstanding shares of Series B Preferred Stock
as of such date or (b) the fifth anniversary of the Closing Date.  The Series B
Preferred Stock will not be convertible into Common Stock and the Warrants will
not be exercisable for shares of Common Stock unless and until the holders of
outstanding Common Stock approve the issuance of the Common Stock upon such
conversion or exercise.

     If the Company does issue shares of Common Stock upon conversion of the
Series B Preferred Stock or upon exercise of the Warrants (collectively, the
"Conversion Shares"), the holders of the Conversion Shares will have certain
rights to require the Company to register the Conversion Shares for resale under
the Securities Act.

     The Series B Preferred Stock and Warrants were offered and sold to certain
existing stockholders of the Company.  Richard Talarico, a director and
executive officer of the Company, purchased 300 shares, James Roddey and William
Kavan, directors of the Company, purchased 100 shares and 750 shares,
respectively, and Henry Posner, Jr. and Thomas D. Wright, stockholders of the
Company, purchased 1,400 and 200 shares, respectively.

     The Company intends to pursue refinancing and/or repayment of the $6.2M
Note through bank financing, the sale of operating assets or a combination of
the two.  However, the Company does not presently have any commitment in place
for bank financing or the sale of assets.

Changes in Management of the Company

     James S. Kelly, Jr., the founder and the President and Chief Executive 
Officer of KCS prior to its acquisition by the Company, was elected, effective
as of the closing of the KCS Acquisition, as a director of the Company to serve
in such capacity until the next annual meeting of stockholders of the Company.
Mr. Kelly has been involved in the information technology field for 25 years.
Mr. Kelly now owns 724,675 shares of Common Stock which represent approximately
12.10% of the Common Stock issued and outstanding. Mr. Kelly also received the
Notes in connection with the closing of the KCS Acquisition and may receive
additional shares of Common Stock if any Contingent Stock Consideration is paid.

     Ronald J. Pearce, an Executive Vice President and Chief Operating Officer
of KCS prior to its acquisition by the Company, will continue as Chief Operating
Officer of KCS following the KCS Acquisition.   Mr. Pearce joined KCS in 1990.

Item 5.  Other Information.

Description of Capital Stock

     The following is a description of certain provisions of the Company's
Certificate of Incorporation (the "Certificate"), Certificate of Designation
(the "Series A Designation") relating to the Company's Series A Convertible
Redeemable Preferred Stock, par value $.01 per share (the "Series A Preferred
Stock"), the Certificate of Designation (the "Series B Designation") for the
Series B Redeemable Preferred Stock (the "Series B Preferred Stock"), and By-
Laws (the "By-Laws").  Such summary does not purport to be complete and is
qualified in its entirety by reference to the terms of the foregoing documents.

     The Company is authorized to issue up to 20,000,000 shares of Common Stock,
par value $0.01 per share, and 100,000 shares of preferred stock, par value $.01

Common Stock

     Holders of Common Stock are entitled to one vote for each share held of
record on all matters to be submitted to a vote of the stockholders.  The
Certificate does not provide for cumulative voting for the election of
directors.  Subject to preferences that may be applicable to any outstanding
shares of Preferred Stock, holders of Common Stock are entitled to receive
ratably such dividends, if any, as may be declared from time to time by the
Board of Directors of the Company out of funds legally available therefor.  The
holders of Common Stock have no preemptive or other subscription rights, and
there are no conversion rights or redemption or sinking fund provisions with
respect to the Common Stock.  All outstanding shares of Common Stock are fully
paid and nonassessable.  In the event of any liquidation, dissolution or
winding-up of the affairs of the Company, holders of Common Stock will be
entitled to share ratably in the assets of the Company remaining after payment
or provision for payment of all of the Company's debts and obligations and
liquidation payments to holders of outstanding shares of Preferred Stock.

Series B Convertible Redeemable Preferred Stock

     The holders of Series B Preferred Stock are entitled to receive, when and
as declared by the Company's Board of Directors, cumulative quarterly dividends
at the rate of six percent per annum, from and including the date of issuance to
and including the date of payment in redemption (the "Redemption Date").  Such
dividends, to the extent declared by the Board of Directors, will be payable
quarterly in arrears on each October 31, January 31, April 30 and July 31.  The
holders of Series B Preferred Stock have no voting rights except as provided by
the Delaware General Corporation Law (the "DGCL") and except with respect to
actions which adversely affect the rights and preferences of the Series B
Preferred Stock set forth in the Series B Designation.  The Series B Preferred
Stock is senior in right of payment and on liquidation to the Common Stock and
the Series A Preferred Stock.

     Upon approval by the holders of the outstanding Common Stock, each holder
of the Series B Preferred Stock will have the right to convert all or a portion
of its shares of Series B Preferred Stock into Common Stock at any time prior to
the redemption date.  Until and including the first anniversary of the original
issuance of shares of Series B Preferred Stock, each share of Series B Preferred
Stock held by each holder may be converted into the number of shares of Common
Stock determined by (i) dividing 1,000 by $3.6125, which is 85% of the closing
price of the Common Stock as reported by Nasdaq on the date prior to the Closing
Date, or (ii) if it results in a greater number of shares of Common Stock,
dividing 1,000 by the greater of (A) 85% of the closing price of the Common
Stock as reported by Nasdaq on the trading date prior to the date of the
conversion or (B) $2.00.  After the first anniversary of the original issuance
of shares of Series B Preferred Stock, each share of Series B Preferred Stock
held by each holder may be converted into the number of shares of Common Stock
determined by (i) dividing 1,000 by $3.6125, which is 85% of the closing price
of the Common Stock as reported by Nasdaq on the date prior to the Closing Date,
or (ii) if it results in a greater number of shares of Common Stock, dividing
1,000 by 85% of

                                      -7-
<PAGE>
 
the closing price of the Common Stock as reported by Nasdaq on the first trading
date following the first anniversary of the Closing Date.  Holders of the Series
B Preferred Stock who exercise the foregoing conversion right shall have the
right to receive any accrued, but unpaid dividends.  No fractional shares of
Common Stock shall be issued; instead a cash payment will be made in lieu of the
issuance of any fractional shares of Common Stock.  Any shares of Series B
Preferred Stock which are not converted to Common Stock will remain outstanding
until so converted or until redeemed.

     In the event that the holders of the outstanding Common Stock have not
approved the issuance of Common Stock pursuant to the foregoing conversion
rights on or before December 31, 1998, the Company shall redeem all outstanding
shares of Series B Preferred Stock (subject to the legal availability of funds
therefor) at $1,000 per share of Series B Preferred Stock, plus accrued and
unpaid dividends, if any, on or before December 31, 1998.

     In the event that the Company consummates an Asset Sale prior to the
Maturity Redemption Date (as defined), at the option of the holders of the
Series B Preferred Stock, the Company is to redeem all outstanding shares of
Series B Preferred Stock (subject to the legal availability of funds therefor)
on or before the date which is five business days following consummation of the
Asset Sale.  "Asset Sale" means any sale, issuance, conveyance, transfer, lease
or other disposition (including, without limitation, by way of merger,
consolidation or sale and leaseback transaction) (collectively, a "Transfer") by
the Corporation or its subsidiaries, directly or indirectly, in one or a series
of related transactions, to any person other than the Corporation or any of its
subsidiaries, which Transfer results in net proceeds to the Corporation and its
subsidiaries in an aggregate amount sufficient to repay all then outstanding
debt of the Corporation and its subsidiaries and to pay the redemption price of
$1,000 per share of Series B Preferred Stock, plus accrued and unpaid dividends,
if any.  Unless earlier redeemed or converted into Common Stock, the outstanding
shares are to be redeemed by the Company (subject to the legal availability of
funds therefor) at $1,000 per share, plus accrued and unpaid dividends, if any,
on or before the fifth anniversary of the Closing Date (the "Maturity Redemption
Date").

     Holders of Series B Preferred Stock will have certain pro rata preemptive
rights for one year to subscribe for securities proposed to be issued in
connection with certain future equity financings by the Company, if any.

Series A Convertible Redeemable Preferred Stock

     The holders of Series A Preferred Stock are entitled to receive, when and
as declared by the Company's Board of Directors, cumulative compounded quarterly
dividends at the rate of eight percent of the liquidation value thereof per
annum.  The holders of Series A Preferred Stock have no voting rights except as
provided by the DGCL and except with respect to actions which affect adversely
the rights and preferences of the Series A Preferred

                                      -8-
<PAGE>
 
Stock set forth in the Series A Designation.  The Series A Preferred Stock is
senior in right of payment and on liquidation to the Common Stock.

     The Company has the right at any time prior to maturity, to redeem the
outstanding shares of Series A Preferred Stock at $100 per share, plus accrued
and unpaid dividends, if any.  Unless earlier redeemed, the outstanding shares
of Series A Preferred Stock are to be redeemed by the Company at $100 per share,
plus accrued and unpaid dividends, if any, on June 30, 2006.

     As the outstanding shares of Series A Preferred Stock were not converted to
Common Stock within the permitted time period, they will remain outstanding
until the earlier of the time such shares are redeemed by the Company or June
30, 2006.

Undesignated Preferred Stock

     The Board of Directors of the Company is authorized, without further action
of the stockholders, to issue up to 100,000 shares of Preferred Stock in one or
more classes or series and to fix the designations, powers, preferences and the
relative participating, optional or other special rights of the shares of each
series and any qualifications, limitations and restrictions thereon.  Of such
authorized shares, 40,000 shares have been designated as Series A Preferred
Stock and 5,000 shares have been designated as Series B Preferred Stock.  Any
Preferred Stock issued by the Company may rank prior to the Common Stock as to
dividend rights, liquidation preference or both, may have full or limited voting
rights and may be convertible into shares of Common Stock.

     The issuance of Preferred Stock could have the effect of making it more
difficult for a third party to acquire, or of discouraging a third party from
acquiring or seeking to acquire, a significant portion of the outstanding Common
Stock.

Certain Anti-Takeover Effects of Certificate and By-Laws Provisions

     Certain provisions of the Certificate and By-Laws summarized in the
following paragraphs may be deemed to have anti-takeover effects.  These
provisions may have the effect of discouraging a future takeover attempt which
is not approved by the Board of Directors but which individual Company
stockholders may deem to be in their best interests or in which stockholders may
receive a substantial premium for their shares over then-current market prices.
As a result, stockholders who might desire to participate in such a transaction
may not have an opportunity to do so.  Such provisions also render the removal
of the current Board of Directors more difficult.

     Number of Directors; Removal; Filling Vacancies.  The Certificate and By-
Laws provide that the number of directors will be fixed from time to time with
the consent of two-thirds of the Board of Directors.  Moreover, the Certificate
provides that directors may only be removed with cause by the affirmative vote
of the holders of at least a majority of the

                                      -9-
<PAGE>
 
outstanding shares of capital stock of the Company then entitled to vote at an
election of directors.  This provision prevents stockholders from removing any
incumbent director without cause and allows two-thirds of the incumbent
directors to add additional directors without approval of stockholders until the
next annual meeting of stockholders at which directors are elected.

     Advance Notice of Nominations and Stockholder Proposals.  The By-Laws
contain a provision requiring advance notice by a stockholder of a proposal or
director nomination that such stockholder desires to present at any annual or
special meeting of stockholders, which would prevent a stockholder from making a
proposal or a director nomination at a stockholder meeting without the Company
having advance notice of the proposal or director nomination.  This provision
could make a change in control more difficult by providing the directors of the
Company with more time to prepare an opposition to a proposed change in control.

     Vote Requirement for Calling Special Meeting.  The By-Laws also contain a
provision requiring the vote of the holders of two-thirds of the outstanding
Common Stock in order to call a special meeting of stockholders.  This provision
would prevent a stockholder with less than a two-thirds interest from calling a
special meeting to consider a merger unless such stockholder had first obtained
adequate support from a sufficient number of other stockholders.

     Statutory Business Combination Provision.  The Company is subject to the
provisions of Section 203 ("Section 203") of the DGCL.  Section 203 provides,
with certain exceptions, that a Delaware corporation may not engage in any of a
broad range of business combinations with a person, or an affiliate or associate
of such person, who is an "interested stockholder" for a period of three years
from the date that such person became an interested stockholder unless:  (i) the
transaction resulting in a person becoming an interested stockholder, or the
business combination, is approved by the board of directors of the corporation
before the person becomes an interested stockholder; (ii) the interested
stockholder acquired 85% or more of the outstanding voting stock of the
corporation in the same transaction that makes it an interested stockholder
(excluding shares owned by persons who are both officers and directors of the
corporation, and shares held by certain employee stock ownership plans); or
(iii) on or after the date the person becomes an interested stockholder, the
business combination is approved by the corporation's board of directors and by
the holders of at least 66 2/3% of the corporation's outstanding voting stock at
an annual or special meeting, excluding shares owned by the interested
stockholder.  Under Section 203, an "interested stockholder" is defined (with
certain limited exceptions) as any person that is (i) the owner of 15% or more
of the outstanding voting stock of the corporation or (ii) an affiliate or
associate of the corporation and was the owner of 15% or more of the outstanding
voting stock of the corporation at any time within the three-year period
immediately prior to the date on which it is sought to be determined whether
such person is an interested stockholder.

                                      -10-
<PAGE>
 
     A corporation may, at its option, exclude itself from the coverage of
Section 203 by amending its certificate of incorporation or by-laws by action of
its stockholders to exempt itself from coverage, provided that such by-law or
charter amendment does not become effective until 12 months after the date it is
adopted.  Neither the Certificate nor the By-Laws contains any such exclusion.

Limitations on Liability and Indemnification of Directors and Officers

     Limitations on Liabilities.  Consistent with the DGCL, the Certificate
contains a provision eliminating or limiting liability of directors to the
Company and its stockholders for monetary damages arising from acts or omissions
in the director's capacity as a director.  The provision does not, however,
eliminate or limit the personal liability of a director (i) for any breach of
such director's duty of loyalty to the Company or its stockholders, (ii) for
acts or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law, (iii) for unlawful dividends or unlawful stock
purchases or redemptions as provided in Section 174 of the DGCL or (iv) for any
transaction from which the director derived an improper personal benefit.  This
provision offers persons who serve on the Board of Directors of the Company
protection against awards of monetary damages resulting from breaches of their
duty of care, except as indicated above.  As a result of this provision, the
ability of the Company or a stockholder thereof to successfully prosecute an
action against a director for a breach of his duty of care is limited.  However,
the provision does not affect the availability of equitable remedies such as an
injunction or rescission based upon a director's breach of his duty of care.
The Commission has taken the position that the provision will have no effect on
claims arising under the federal securities laws.

     Indemnification.  The Certificate and By-Laws provide for mandatory
indemnification rights to the maximum extent permitted by applicable law,
subject to limited exceptions, to any director or officer of the Company who, by
reason of the fact that he is a director or officer of the Company, is involved
in a legal proceeding of any nature.  Such indemnification rights include
reimbursement for expenses incurred by such director or officer in advance of
the final disposition of such proceeding in accordance with the applicable
provisions of the DGCL.  The Company also maintains directors' and officers'
liability insurance.

     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers or persons controlling the Company
pursuant to the foregoing provisions, the Company has been informed that in the
opinion of the Commission such indemnification is against public policy as
expressed in the Securities Act and is therefore unenforceable.

                            STOCK PURCHASE AGREEMENT


          THIS STOCK PURCHASE AGREEMENT ("Agreement") is made and entered into

                                 ARTICLE II
                                 Purchase Price

          substantially in the form of Exhibit 2.1(a) hereto, which promissory
          note shall be secured in accordance with the terms of a security
          agreement substantially in the form of Exhibit 2.1(b) hereto (the
          "Security Agreement") and guaranteed in accordance with the terms of a
          guaranty and suretyship agreement substantially in the form of Exhibit
          2.1(c) hereto (the "Guaranty") and shall bear interest at the rate of
          5% per annum (the "6.2m Note"), with $3,000,000 of the principal to be
          due and payable no later than the earlier to occur of (a) the sale of
          a subsidiary of Purchaser or substantially all of the operating assets
          of a subsidiary of Purchaser, and (b) December 31, 1998, and with the
          other $3,200,000 of the principal to be due and payable no later than
          the earlier to occur of (x) the receipt by Purchaser or any affiliate
          of Purchaser of one or more loans from one or more third party lenders
          in amounts in the aggregate at least equal to $3,200,000 in connection
          with the refinancing of the $3,200,000 portion of the 6.2m Note, and
          (y) December 31, 1998; and

               (iii)  a promissory note in the original principal amount of
          $2,000,000 payable to the order of James S. Kelly, Jr. and
          substantially in the form of Exhibit 2.1(d) hereto, which promissory
          note shall be secured by the Security Agreement and guaranteed by the
          Guaranty and shall bear interest at the rate of 6% per annum (the "2m
          Note," and together with the 6.2m Note, the "Notes"), with the
          principal thereof to be due and payable in full on the second (2nd)
          anniversary of the Closing Date (the "Maturity Date"); provided that
          if all principal and accrued and unpaid interest (collectively, the
          "Unpaid Amount"), is not paid in full on the Maturity Date, then,
          subject to the receipt of approval of the shareholders of Purchaser,
          the Unpaid Amount shall

                                      -2-
<PAGE>
 
          automatically be converted to Purchaser Common Stock, the number of
          shares of Purchaser Common Stock to be issued to be determined by
          dividing the Unpaid Amount by (a) the average of the bid and asked
          prices of Purchaser Common Stock for the thirty (30) days preceding
          the earlier of (i) the date of public disclosure of this Agreement or
          (ii) the date which is two (2) business days prior to the Closing Date
          (the "Average Bid and Asked Price"), or (b) at the option of James S.
          Kelly, Jr., the average of the bid and asked prices of Purchaser
          Common Stock for the thirty (30) days preceding the Maturity Date (the
          "Alternate Average Bid and Asked Price"); provided, however, that if
          the Alternate Average Bid and Asked Price is less than $2.00 per share
          of Purchaser Common Stock, the Alternate Average Bid and Asked Price
          shall be deemed, for purposes of this Agreement, to be $2.00 per share
          of Purchaser Common Stock; and

               (iv) the issuance to James S. Kelly, Jr. of 724,675 shares of
          Purchaser Common Stock which is equal to $3,192,918.30 divided by the
          Average Bid and Asked Price of $4.406; and

               (v) the issuance to Ronald J. Pearce of 80,520 shares of
          Purchaser Common Stock, which is equal to $354,768.70 divided by the
          Average Bid and Asked Price of $4.406.

The cash portion of the Closing Payment will be made on the Closing Date by wire
transfer of immediately available funds to one or more accounts identified by
the Shareholders at least three (3) business days prior to the Closing,
Purchaser hereby acknowledging its timely receipt of all such wire transfer
instructions.  Purchaser acknowledges and agrees that the Closing Payment has
already been reduced by $209,252, which represents the total remaining unpaid
amount of the Company's liability for income taxes related to the Company's
change from the cash basis to the accrual basis of accounting (the "Tax
Liability"), and except as set forth in Section 2.2, no further adjustment to
the Purchase Price shall be made on account of the Tax Liability.  At the
Closing the Purchaser shall deliver to James S. Kelly, Jr. and Ronald J. Pearce
a certificate executed by the Chief Executive Officer of Purchaser certifying
the Average Bid and Asked Price.  The following chart summarizes the Closing
Payment described above:

          2.1.3 Adjusted Operating Profit.  The term "Adjusted Operating
Profit" means

               (a) the net profit of the Company, determined on an accrual basis
          in accordance with generally accepted accounting principles
          consistently applied ("GAAP") (Purchaser hereby acknowledges that the
          Company has made certain changes in its accounting methods, from the
          cash method to the accrual method, such changes being applied in
          respect of periods commencing on or after January 1, 1997), before
          interest income or expense, loss or gain on the sale of assets, any
          prior period adjustments and income taxes,

          plus

               (b) expenses related to the following items incurred from January
          1, 1998 through the Closing Date (the parties hereby acknowledging
          that while August 1, 1998 is the Accounting Effective Date, that they
          intend the following expenses to be determined through the Closing
          Date, not the Accounting Effective Date, as such term is defined in
          Section 3.1):

                    (i)   salary, wage taxes, benefits and other expenses
               associated with the employment of James S. Kelly, Jr., not to
               exceed $30,500 per month;

                    (ii)  salaries, wage taxes and benefits associated with the
               elimination of the positions of the Company's Administrative
               Office Manager and Administrative Support Person which are not
               filled prior to December 31, 1998, not to exceed $7,200 per
               month; and

                    (iii) Professional fees for investment bankers, attorneys
               and outside accountants incurred by Company prior to June 19,
               1998 in connection with the anticipated sale of the Shares.

          2.1.4  Accounting Procedures.

               (a) For calendar year 1998, Purchaser shall prepare a report
          containing a balance sheet of the Company, and a related statement of
          income for the twelve (12) months ending December 31, 1998, prepared
          in accordance with GAAP consistently applied (Purchaser hereby
          acknowledging that the Company has made certain changes in its
          accounting methods, from the cash method to the accrual method, such
          changes being applied in respect of periods commencing on or after
          January 1, 1997), together with a statement setting forth the Earn-out
          Payment (including the calculation of Adjusted Operating Profit) and
          all other adjustments required to be made to such financial statements
          in order to make the calculations required under Section

                                      -5-
<PAGE>
 
          2.1.2 (the "Earn-out Determination").  A copy of the Earn-out
          Determination shall be delivered to the Shareholders' Representative
          not later than February 28, 1999.

               (b) If the Shareholders' Representative does not agree that the
          Earn-out Determination delivered pursuant to clause (a) above
          correctly states the Earn-out Payment, the Shareholders'
          Representative shall promptly (but not later than 60 days after the
          delivery of such Earn-out Determination) give written notice to
          Purchaser of any exceptions thereto (in reasonable detail describing
          the nature of the disagreement asserted).  If the Shareholders'
          Representative and Purchaser reconcile their differences within twenty
          (20) days after Purchaser's receipt of such written notice, the Earn-
          out Determination shall be adjusted accordingly and shall thereupon
          become final and conclusive upon all of the parties hereto and
          enforceable in a court of law.  If the Shareholders' Representative
          and Purchaser are unable to reconcile their differences in writing
          within 20 days after written notice of exceptions is received by
          Purchaser, the Purchaser shall promptly, but not later than sixty (60)
          days after the end of such 20-day period deliver to the Shareholders'
          Representative, the financial statements described in Section 2.1.4(a)
          above, audited by Arthur Andersen or such other independent accounting
          firm then auditing the books of Purchaser (the "Accountants").  If
          within a period of thirty (30) additional days after receipt of such
          audited financial statements the Shareholders' Representative and the
          Purchaser are still unable to resolve or reconcile their differences,
          the items in dispute shall be submitted to the Pittsburgh office of
          Deloitte & Touche or its successors (the "Arbitrator") for final
          determination, and the Earn-out Determination shall be deemed adjusted
          in accordance with the determination of the Arbitrator and shall
          become final and conclusive upon all of the parties hereto and
          enforceable in a court of law.  For purposes of this Agreement, any
          item not accepted in writing by both Purchaser and the Shareholders'
          Representative shall be deemed to be in dispute.  Each of the
          Shareholders' Representative and Purchaser shall be entitled to submit
          items in dispute to the Arbitrator.  Both parties shall request in
          their initial submissions that the Arbitrator render its decision as
          to items in dispute as soon as possible, but in no event later than
          sixty (60) days following the initial submission.

               (c) In the event the Arbitrator shall have, at any time during
          the period it might be called upon to determine a dispute under this
          Section 2.1.4, performed auditing or other services for Purchaser or
          the Shareholders (other than as an arbitrator in other dispute
          proceedings), or for any other reason is unable or unwilling to
          perform the services required of it under this Section, then Purchaser
          and the Shareholders' Representative agree to select another
          accounting firm from among the six largest accounting firms in the
          United States in terms of gross revenues to perform the services to be
          performed

                                      -6-
<PAGE>
 
          under this Section 2.1.4 by the Arbitrator.  If the Purchaser and the
          Shareholders' Representative fail to select another accounting firm
          within 15 days after it is determined that the Arbitrator will not
          perform the services required, either Purchaser or the Shareholders'
          Representative may request the American Arbitration Association in
          Pittsburgh, Pennsylvania to appoint an independent firm of certified
          public accountants of recognized national standing to perform the
          services required under this Section 2.1.4 by the Arbitrator.  For
          purposes of this Agreement, the term "Arbitrator" shall include such
          other accounting firm chosen in accordance with this clause (c).

               (d) The fees and expenses of the Arbitrator shall be shared
          equally by Purchaser, on the one hand, and the Shareholders on the
          other hand.

               (e) The books and records of the Company shall be made available
          during normal business hours upon reasonable advance notice at the
          principal office of the Company, to Purchaser, the Shareholders and to
          the Arbitrator (or if applicable, such other accounting firm selected
          in accordance with Section (c) above).  Purchaser and the Shareholders
          shall use their best efforts to cause all information required by the
          Arbitrator to be submitted on a timely basis such that the Arbitrator
          will be able to render a decision within sixty (60) days after the
          initial submission of items in dispute.

               (f) The Earn-out Payment shall be paid within ten (10) days of
          the date the Earn-out Determination becomes final.  The date on which
          the Earn-out Payment is made shall be referred to herein as the "Earn-
          out Payment Date."

          2.2  Adjustment to Purchase Price.  The Closing Payment of $14,190,748
(in cash, Purchaser Common Stock and the Notes) is based on the assumption that
(a) at the Closing the Company will have no indebtedness other than (i) bank
indebtedness not to exceed $675,000, (ii) accounts payable in the ordinary
course of business, and (iii) capital lease obligations existing as of June 18,
1998, all of which are set forth on Schedule 4.5 (all of the foregoing,
collectively, the "Permitted Indebtedness"), and (b) that the Tax Liability
shall not exceed $209,252.  If (a) the Company on the Closing Date has
indebtedness other than $675,000 or less of bank indebtedness, accounts payable
other than in the ordinary course of business, or capital lease obligations in
excess of those set forth on Schedule 4.5, or (b) if the Tax Liability exceeds
                             ------------                                     
$209,252, the cash portion of the Closing Payment shall be reduced dollar for
dollar by the amount of the difference between such indebtedness and the
Permitted Indebtedness, or the difference between (i) the unpaid amount of the
Company's actual liability for income taxes related to the Company's change, as
of January 1, 1997, from the cash basis to the accrual basis of accounting and
(ii) $209,252, as the case may be.

                                      -7-
<PAGE>
 
          2.3  Retained Liabilities of Shareholders.  Notwithstanding anything
in this Agreement to the contrary, Shareholders shall retain all liability for
(a) all sales and use tax obligations of the Company through the Closing Date to
the extent not reserved for on the Company's Financial Statements (as defined in
Section 4.4), (b) severance obligations payable to the Company's Administrative
Office Manager and Administrative Support Person and (c) any Tax Liability in
excess of $209,252 which is not deducted from the Purchase Price as provided in
Section 2.2 ("Retained Liabilities").

          2.4  Closing Payment Adjustment Mechanism.  Not fewer than two
business days before the Closing Date, the Shareholders and the Company will
prepare and deliver to Purchaser a balance sheet (together with notes thereto
and any related schedules) of the Company (the "Closing Balance Sheet")
reflecting, among other things, the Shareholders' best estimate of the
indebtedness of the Company (which for purposes of this Section 2.4 shall mean
indebtedness of the types described in clause (a) of Section 2.2 hereof) as of
11:59 p.m. on the Accounting Effective Date.  Based on the foregoing, the
Shareholders and the Company shall prepare and deliver a certificate
("Shareholders' Balance Sheet Certificate") to Purchaser certifying that, to the
best knowledge of the Shareholders and the Company, the Closing Balance Sheet
fairly sets forth the indebtedness of the Company estimated as of 11:59 p.m. on
the Accounting Effective Date in accordance with GAAP applied in a manner
consistent with the Last Balance Sheet (as defined in Section 4.4 hereof).  In
the event Purchaser disagrees with any item on the Shareholders' Balance Sheet
Certificate and Purchaser and the Shareholders' Representative are unable to
resolve such disagreement within thirty (30) days after the Closing, then
Purchaser shall have the right to cause Arthur Andersen (the "Auditor"), within
60 days after the Closing, to audit the Closing Balance Sheet in accordance with
GAAP applied in a manner consistent with the Last Balance Sheet and make any
adjustments thereto that are necessary, in the Auditor's professional opinion,
to render the Closing Balance Sheet as fairly representing the indebtedness of
the Company as of 11:59 p.m. on the Accounting Effective Date (the Closing
Balance Sheet, as so adjusted by the Auditor, the "Adjusted Closing Balance
Sheet.")  If Purchaser elects to have the Auditor audit the Closing Balance
Sheet, the Auditor shall, within 60 days after the Closing Date, deliver to
Purchaser and the Shareholders the Adjusted Closing Balance Sheet, notes thereto
and auditor's report thereon.  Within 60 days of receipt of the Adjusted Closing
Balance Sheet, the Shareholders will either accept the Adjusted Closing Balance
Sheet or provide Purchaser with written objections thereto.  If the Shareholders
accept the Adjusted Closing Balance Sheet as presented or fail to object within
the 60-day period, then the Adjusted Closing Balance Sheet and the indebtedness
of the Company reflected therein will be deemed to be final and binding on the
parties.  In such event, if the indebtedness of the Company as of 11:59 p.m. on
the Accounting Effective Date reflected on the Adjusted Closing Balance Sheet
exceeds the Permitted Indebtedness, then the Shareholders shall, within 30 days
after the acceptance by the Shareholders of the Adjusted Closing Balance Sheet
or the expiration without objection thereto within such 60-day period, as the
case may be, pay by wire transfer to the Purchaser, any amounts needed to adjust
the Closing Payment as provided in Section 2.2 hereof in order to reflect the
changes made from the estimated indebtedness of the Company set forth in the
Shareholders' Balance Sheet Certificate caused

                                      -8-
<PAGE>
 
by the Adjusted Closing Balance Sheet as so audited by the Auditor.  Any
disagreement between the Purchaser and the Shareholders that cannot be resolved
within 30 days after receipt of the Shareholders' written objections will be
resolved by the Shareholders selecting a firm of certified public accountants of
national reputation to resolve the dispute.  If the Auditor and the
Shareholders' accountants cannot resolve the dispute within 30 days after
submission to them, then the Auditor and the Shareholders' accountants shall
select a third firm of certified public accountants of national reputation and
the amount of indebtedness of the Company as of 11:59 p.m. on the Accounting
Effective Date shall be the average of (a) the median of the three
determinations of indebtedness and (b) whichever of the remaining two
determinations is closest to such median, and such amount shall be binding on
the parties and subject to judicial enforcement, and the Shareholders shall,
within 30 days after the expiration of such 30-day period, pay by wire transfer
to the Purchaser, any amounts needed to adjust the Closing Payment as provided
in Section 2.2 hereof in order to reflect the changes made from the estimated
indebtedness of the Company set forth in the Shareholders' Balance Sheet
Certificate caused by the Adjusted Closing Balance Sheet as so determined.
Purchaser, on the one hand, and the Shareholders, on the other hand, shall bear
all costs of its or their own accountants and one-half of the cost of the third
accounting firm, if any.

or waiver of the conditions set forth in Articles IX and X or on such other date
and at such other time and place as the parties may agree, but in any event on
or before August 14, 1998.  In this Agreement, such event is referred to as the
"Closing" and such date and time are referred to as the "Closing Date."  The
Closing shall be effective at 12:01 a.m., prevailing time on the Closing Date;
provided, however, that for accounting purposes only, the Closing shall be
effective as of 12:01 a.m., prevailing time, on August 1, 1998 (the "Accounting
Effective Date"), so that all revenues and expenses of the Company for the
period from August 1, 1998 until the Closing Date shall be for the account of
Purchaser.

                         Representations and Warranties
                      of the Company and the Shareholders

the transactions contemplated hereby, the Company and the Shareholders jointly

     Date, or by the Company or any Affiliate of the Company of which such
     Shareholder is consciously aware during the Restricted Period; (a) provided
     that the prohibition contained in this Section 11.3.1.1 shall not apply to
     any activity in which the Company for a period of more than 180 consecutive
     days ceases to be engaged, (b) provided that the ownership, beneficially or
     of record, of less than five percent (5%) of the outstanding shares of any
     class of stock of any issuer listed on a national securities exchange shall
     not be a breach of this Agreement and (c) provided that neither the
     ownership of shares of Purchaser Common Stock to be issued to James S.
     Kelly, Jr. and Ronald J. Pearce pursuant to this Agreement, nor any
     activities of James S. Kelly, Jr. conducted by him on behalf of Purchaser
     (whether as a member of Purchaser's Board of Directors or otherwise) or the
     Company from and after the Closing shall be a breach of this Agreement.

               11.3.1.2  Unless required by law or unless the use thereof is
     necessary or appropriate in connection with any claim made for
     indemnification under this Agreement, no Shareholder shall, directly or
     indirectly, at any time following the Closing Date, divulge, communicate,
     use to the detriment of Company or any Affiliates of Company, or for the
     benefit of any other business, firm, person, partnership, limited liability
     company or corporation, the confidential information, data, intellectual
     property or trade secrets of Company, including but not limited to those
     items identified on Schedule 4.11, and the business records, financial
     information and the customer, supplier and personnel information of
     Company.

               11.3.1.3  No Shareholder shall, directly or indirectly, for a
     period of five years following the Closing Date: (i) induce any customer of
     Company at the Closing Date to patronize any business (other than the
     Company) similar to any of those described in Section 11.3.1.1; (ii)
     canvass, solicit or accept from any customer of Company at the Closing Date
     any business similar to any of those described in Section 11.3.1.1 other
     than on behalf of the Company; or (iii) request or advise any individual or
     entity which is a customer of Company at the Closing Date to withdraw,
     curtail or cancel any such customer's business with the Company.

               11.3.1.4  No Shareholder shall, directly or indirectly, for a
     period of five years following the Closing Date, solicit (or employ or
     cause to be employed other than by the Company) employees of Company or any
     Affiliate or subsidiary of Company of which such Shareholder is consciously
     aware, directly or indirectly, for the purpose of enticing them to leave
     their employment with Company, or any such Affiliate or subsidiary of
     Company.

               11.3.1.5  No Shareholder shall, directly or indirectly, for a
     period of five years following the Closing Date, request or advise any
     individual or entity

                                      -35-
<PAGE>
 
     which is a supplier or vendor of Company at the Closing Date to withdraw,
     curtail or cancel any such supplier's or vendor's business with Company.

          11.3.2  The Shareholders agree and acknowledge that the restrictions
     contained in Section 11.3.1 have been specifically negotiated by
     sophisticated parties and agree that all such provisions are reasonable and
     necessary in territorial scope and in duration to adequately protect
     Purchaser and the Company after the Closing.  If, however, any provision of
     Section 11.3.1, as applied to any party or to any circumstances, is
     adjudged by a court of competent jurisdiction to be invalid or
     unenforceable, the same will in no way affect any other provision of
     Section 11.3 or any other part of this Agreement, the application of such
     provision in any other circumstances or the validity or enforceability of
     this Agreement.  If any such provision, or any part thereof, is held to be
     unenforceable because of the duration of such provision or the area covered
     thereby, the parties agree that the court making such determination will
     have the power to modify the duration and/or area of such provision, and/or
     to delete specific words or phrases, and in its modified form such
     provision will then be enforceable and will be enforced.  It is further
     agreed that a breach or violation of any provision of Section 11.3.1 will
     result in immediate and irreparable injury to Purchaser and the Company and
     that money damages will be an inadequate remedy.  Accordingly, in addition
     to such damages as Purchaser and the Company can demonstrate they have
     sustained by reason of such breach or violation, and in addition to any
     other remedy that Purchaser or the Company may have, Purchaser and the
     Company shall each be entitled to both temporary and permanent injunctive
     relief to enforce the specific performance of this Section 11.3.

          11.3.3  The period of time during which a Shareholder is prohibited
     from engaging in certain activities pursuant to the terms of this Section
     11.3 shall be extended by the length of time during which such Shareholder
     is in breach of the terms of this Section 11.3.

          11.3.4  Notwithstanding the foregoing, neither Joseph J. Kelly nor
     Bradley C. Friedel shall be bound by the terms of Section 11.3.1.3 hereof
     at any time after the employment of such Shareholder by the Company is
     terminated by the Company or Purchaser after the Closing.

          11.4    Conduct of Business During Earn-Out Period.  At all times
during the Earn-Out Period, except as otherwise provided by the prior written
consent of the Shareholders' Representative, which consent shall not be
unreasonably withheld, delayed or conditioned, Purchaser agrees on behalf of
itself and the Company that:

          11.4.1  The Company will in all material respects, as a separate
     corporation and with no consolidation of its business or operations (or the
     results thereof) with those of Purchaser or any other entity, and with no
     charge to the Company for any corporate overhead or other operating
     expenses of Purchaser or any other entity other

                                      -36-
<PAGE>
 
     than such charges as are solely attributable to the Company and its
     business and operations (or if any such charge to the Company is made in
     respect of expenses of Purchaser or any other entity, all such charges are
     to be completely disregarded for purposes of the calculation of the Earn-
     Out Payment), conduct its business and operations in the manner in which
     the same have heretofore been conducted, including without limitation,
     ordinary course (a) collection of accounts receivable, (b) maintenance of
     inventory levels, (c) payment of accounts payable, and (d) payment of other
     indebtedness, including bank indebtedness.  The Company will use all
     commercially reasonable efforts to (i) preserve its business organization
     intact; (ii) keep available to the Company the services of its officers,
     employees, agents and distributors; (iii) preserve its relationships with
     customers, suppliers and others having dealings with the Company; and (iv)
     maintain in all material respects the quantity, quality and condition of
     the Company's assets and the quality of the Company's services to customers
     in accordance with past practices; and

          11.4.2  The Company will maintain all of its properties in customary
     repair, order and condition, reasonable wear and use and damage by
     unavoidable casualty excepted, and will maintain insurance of such types
     and in such amounts upon all of its properties and with respect to the
     conduct of its business as are in effect on the Closing Date; and

          11.4.3  The Company will not (i) authorize or issue any shares of its
     capital stock (including any held in its treasury) or any other securities,
     or take any other action which would dilute the percentages of Purchaser
     Common Stock to be respectively held by James S. Kelly, Jr. and Ronald J.
     Pearce pursuant to this Agreement; (ii) declare or pay any dividend or make
     any other distribution of or with respect to its shares of capital stock or
     other securities or purchase or redeem any shares of its capital stock or
     other securities; (iii) pay any bonus or increase the rate of compensation
     of, any of its employees except as may be contractually required or
     consistent with the Company's past employment practices as of the Closing
     Date, or other than as may be required in connection with the conduct of
     the Company's business, enter into any new employment agreement or amend
     any existing employment agreement to increase any bonus or rate of
     compensation payable by the Company thereunder; (iv) employ or otherwise
     retain any person to serve as the Chief Executive Officer, President,
     Administrative Office Manager or Administrative Support Person of the
     Company, or any position analogous thereto; (v) sell or transfer any of its
     assets or acquire assets, other than in the ordinary course of business
     (including, without limitation, sales of inventory made in the ordinary
     course); (vi) make or obligate itself to make capital expenditures
     aggregating more than $50,000; (vii) incur any material obligations or
     liabilities or enter into any material transaction in excess of $100,000;
     or (viii) waive any rights of material value.

          11.5    Other Matters During Earn-Out Period.  At all times during the
Earn-Out Period, except as otherwise provided by the prior written consent of
the

                                      -37-
<PAGE>
 
Shareholders' Representative, which consent shall not be unreasonably withheld,
delayed or conditioned, Purchaser will not (a) except in connection with the
financing of the cash portion of the Closing Payment, authorize or issue any
shares of its capital stock (including any held in its treasury), (b) declare or
pay any dividend payable in shares of its capital stock or undergo any stock
split or recapitalization, or purchase or redeem any shares of its capital
stock, (c) merge or consolidate with any other entity, or enter into any other
business combination with any other entity, in which Purchaser is not the entity
surviving such merger, consolidation or business combination; or (d) or enter
into any division.

          11.6 Access to Records.  For a period of seven years following the
Closing, and for so long thereafter as any one or more of the Shareholders is
contesting or defending against any action, suit, proceeding, hearing,
investigation, charge, complaint, claim or demand in connection with any
indemnification claim made against such Shareholders as set forth in Section
12.1 hereof, neither Purchaser nor the Company, nor any successor to Purchaser
or the Company, shall discard, destroy or otherwise dispose of any records,
documents or data relating to the Company without first making such records,
documents and data available to each Shareholder for inspection and copying.

          12.1.2  The Company and the Purchaser each agree to give prompt
     written notice to the Shareholders of any claim against the Company or the
     Purchaser which might give rise to a claim by the Company or the Purchaser
     against the Shareholders based on the indemnity agreement set forth in
     Section 12.1 hereof, stating the nature and basis of the first-mentioned
     claim and the amount thereof. Subject to the last sentence of this Section

     proceeding. The parties agree to render to each other such assistance as
     may reasonably be requested in order to insure the proper and adequate
     defense of any such dispute, action, suit or proceeding. Notwithstanding
     the foregoing, the Shareholders may compromise and settle any claim, action
     or suit for which they must indemnify the Company and/or the Purchaser
     hereunder, provided that they give the Company and/or the Purchaser, as the
     case may be, advance notice of any proposed compromise or settlement and
     shall obtain the consent of the Company and/or the Purchaser, as the case

     Agreement, or (ii) resulting from any breach of the covenants or agreements
     of the Purchaser in this Agreement.

          12.2.2  The Shareholders each agree to give prompt written notice to
     the Company and the Purchaser of any claim against the Shareholders, or any
     of the Shareholders, which might give rise to a claim by the Shareholders
     against the Company and the Purchaser based on the indemnity agreement set
     forth in Section 12.2 hereof, stating the nature and basis of the first-
     mentioned claim and the amount thereof.  Subject to the last sentence of

     dispute, action, suit or proceeding subject to indemnification by the
     Company and the Purchaser hereunder, including, without limitation, the

     proceeding.  The parties agree to render to each other such assistance as
     may reasonably be requested in order to insure the proper and adequate
     defense of any such dispute, action, suit or proceeding.  Notwithstanding
     the foregoing, the Company and the Purchaser may compromise and settle any
     claim, action or suit for which they must indemnify the Shareholders
     hereunder, provided that they give the Shareholders advance notice of any
     proposed compromise or settlement and shall obtain the consent of the
     Shareholders to such proposed compromise or settlement, which consent shall
     not be unreasonably withheld, delayed or conditioned.

          12.3 Right of Set Off.  Without limiting all other remedies available
to Purchaser, Purchaser shall have the right to set off Indemnifiable Damages
actually sustained by Purchaser or the Company against the Earn-out Payment (but
in no event against amounts due under the Notes).

          12.4 Limitations on Indemnification Obligations.  Any claim for
indemnification made under this Article XII, whether such claim is made by the
Company and/or Purchaser in respect of Indemnifiable Damages, or by the
Shareholders in respect of Losses, must be brought within a period of twenty-
four (24) months after the Closing Date.  In addition, neither the Shareholders
nor the Company and/or Purchaser shall be liable for any Indemnifiable Damages
or Losses, as applicable, until the aggregate amount thereof exceeds $100,000,
but the indemnifying party shall be liable for the entire excess up to the
amount of the Cap.

Ronald J. Pearce represents and warrants that:

             (a) he is an "Accredited Investor" as that term is defined in
         Regulation D under the Securities Act of 1933, as amended (the

             (b) the Purchaser Common Stock, and in the case of James S. Kelly,
         Jr. only, the Notes, are being acquired and will be acquired for his
         own account and will not be sold or otherwise disposed of except
         pursuant to (i) an exemption or exclusion from the registration
         requirements under the Securities Act, which does not require the
         filing by Purchaser with the Securities and Exchange Commission
         ("Commission") of any registration statement, offering circular or
         other document, in which case such Shareholder shall first supply to
         Purchaser an opinion of counsel (which opinion of counsel shall be
         satisfactory to Purchaser) that such exemption or exclusion is
         available or (ii) a registration statement filed by Purchaser with the
         Commission under the Securities Act;

         not be sold, transferred or otherwise disposed of by the holder without
         an effective registration statement being filed under and pursuant to
         said Act or receipt of an opinion of counsel in form and substance
         satisfactory to the [issuer] [maker] that an exemption from
         registration is available.

and Purchaser may, unless (a) an exemption or exclusion from the registration
requirements of the Securities Act is available and Purchaser has received a
satisfactory opinion of counsel with respect thereto, or (b) a registration
statement covering such shares is in effect, place stop transfer orders with its
transfer agents with respect to such certificates.

         13.3  Registration Rights for Purchaser Common Stock.

         13.3.1  Demand Registration Rights.

                 13.3.1.1  Purchaser Common Stock Issued at Closing.  At any
         time following the Closing Date and prior to the Earn-out Payment Date,
         and on one occasion only, Purchaser shall, as soon as practicable but
         in any event within ninety (90) days following a written request from
         the Shareholders' Representative to register the shares of Purchaser
         Common Stock held by James S. Kelly, Jr. and Ronald J. Pearce, file a
         registration statement with the Commission with respect to the shares
         of Purchaser Common Stock issued pursuant to Section 2.1.1.

                 13.3.1.2  Earn-out Common Stock.  At any time following the
         Earn-out Payment Date, and on one occasion only, Purchaser shall as
         soon as practicable but in any event within ninety (90) days following
         a written request from the Shareholders' Representative to register the
         shares of Purchaser Common Stock held by James S. Kelly, Jr. and Ronald
         J. Pearce (whether received at the Closing or on the Earn-out Payment
         Date), file a registration statement with the Commission with respect
         to the shares of Purchaser Common Stock held by such Shareholders.
         Notwithstanding anything in this Agreement to the contrary, if such
         Shareholders have not exercised the demand registration right provided
         in Section 13.3.1.1 as of the Earn-out Payment Date, such demand
         registration right shall

                                      -42-
<PAGE>
 
         terminate on the Earn-out Payment Date and Shareholders shall have only
         the demand registration right described in this Section 13.3.1.2 and
         the piggyback registration rights described in Section 13.3.2.

         13.3.2  Piggyback Registration Rights.  At any time following the
    Closing Date, whenever Purchaser proposes to register any Purchaser Common
    Stock for its own or others' account under the Securities Act, other than
    registrations relating to Plans, Purchaser shall give the Shareholders'
    Representative prompt written notice of its intent to do so.  Upon the
    written request of James S. Kelly, Jr. and Ronald J. Pearce given by the
    Shareholders' Representative within 30 days after receipt of such notice,
    Purchaser shall cause to be included in such registration all of the
    Purchaser Common Stock issued to such Shareholders pursuant to this
    Agreement which any such Shareholder requests, provided that, if Purchaser
    is advised in writing in good faith by any managing underwriter of an
    underwritten offering of the securities being offered pursuant to any
    registration statement under this Section 13.3.2 that the number of shares
    to be sold by persons other than Purchaser is greater than the number of
    such shares which can be offered without adversely affecting the offering,
    Purchaser may reduce pro rata the number of shares offered for the accounts
    of such persons (other than Purchaser) (based upon the number of shares
    proposed to be sold by each such person) to a number deemed satisfactory by
    such managing underwriter.

         13.3.3  Registration Procedures.  All expenses incurred in connection
    with a registration of Purchaser Common Stock held by James S. Kelly, Jr.
    and Ronald J. Pearce under Section 13.3.1 (including all registration,
    filing, qualification, legal, printer and accounting fees, and underwriting
    commissions and discounts with respect to any Purchaser Common Stock sold on
    behalf of such Shareholders ("Expenses")), shall be borne by James S. Kelly,
    Jr. and Ronald J. Pearce, provided, however, that such Shareholders shall
    not be responsible for Expenses in excess of $30,000, and all Expenses in
    excess of such amount shall be borne by Purchaser.  All Expenses incurred in
    connection with a registration statement under Section 13.3.2 shall be borne
    pro rata by James S. Kelly, Jr. and Ronald J. Pearce in the proportion that
    the number of shares of Purchaser Common Stock being registered on behalf of
    such Shareholders bears to the total number of shares of Purchaser Common
    Stock included in such registration statement.  Furthermore, in the event
    that the Purchaser Common Stock held by such Shareholders is registered
    together with shares of Purchaser Common Stock held by third parties
    (whether in a piggyback registration or a demand registration), the terms
    under which such Shareholders and such other holders of Purchaser Common
    Stock reimburse Purchaser for the Expenses associated with such registration
    shall be consistent.  In connection with registrations under Section 13.3,
    Purchaser shall (i) use its best efforts to cause each such registration
    statement, after filing, to promptly become and remain effective for a
    period of at least 120 days (or such shorter period during which James S.
    Kelly, Jr. and Ronald J. Pearce shall have sold all Purchaser Common Stock
    which they requested to be registered); (ii) use its best efforts to
    register and qualify the Purchaser Common Stock covered by such registration
    statement under applicable state

                                      -43-
<PAGE>
 
    securities laws as such Shareholders shall reasonably request for the
    distribution of the Purchaser Common Stock; (iii) take all actions necessary
    to have the Purchaser Common Stock covered by such registration listed or
    quoted on the exchange or automated quotation system on which the Purchaser
    Common Stock trades at the time of registration; and (iv) take such other
    actions as are reasonable and necessary to comply with the requirements of
    the Securities Act and the regulations thereunder.

         13.3.4  Underwriting Agreement.  In connection with each registration
    pursuant to Section 13.3 covering an underwritten registered public
    offering, Purchaser and James S. Kelly, Jr. and Ronald J. Pearce agree to
    enter into a written agreement with the managing underwriters in such form
    and containing such provisions as are reasonably acceptable to James S.
    Kelly, Jr. and Ronald J. Pearce and customary in the securities business for
    such an arrangement between such managing underwriters and companies of
    Company's size and investment stature, provided that the indemnification
    provisions thereof shall be limited to provide that James S. Kelly, Jr. and
    Ronald J. Pearce shall not indemnify such managing underwriters for any
    liability resulting from, or arising out of, or in connection with, any
    misrepresentation by the Purchaser to the underwriters or in any
    registration statement or prospectus.

         13.3.5  Availability of Rule 144.  Purchaser shall not be obligated to
    register shares of Purchaser Common Stock held by James S. Kelly, Jr. or
    Ronald J. Pearce at any time when the resale provisions of Rule 144(k) (or
    any successor provision) promulgated under the Securities Act are available
    to James S. Kelly, Jr. or Ronald J. Pearce for such shares.

         13.3.6  Market Standoff.  In consideration of the granting to James S.
    Kelly, Jr. and Ronald J. Pearce of the registration rights under this
    Section 13.3, such Shareholders agree that they will not sell, transfer or
    otherwise dispose of, including without limitation through put or short sale
    arrangements, shares of Purchaser Common Stock in the 10 days prior to the
    effectiveness of any registration of Purchaser Common Stock for sale to the
    public and for up to 180 days following the effectiveness of such
    registration; provided, however, that during the 180-day period following
    the effectiveness of such registration the Shareholders shall be entitled to
    sell, transfer or otherwise dispose of any or all of their shares of
    Purchaser Common Stock that are registered pursuant to such registration.

         14.1  Transaction Expenses; Brokers' Fees.  Each party shall bear its
own expenses including without limitation legal, accounting and other
transaction expenses incurred in connection with the transactions contemplated

                                      -44-
<PAGE>
 
connection with the transactions contemplated hereby.  The parties hereto
expressly acknowledge and agree that the Company, and not the Shareholders,
shall bear the fees and expenses of the Company's accountants Grossman Yanak &
Ford, LLP in respect of such accountants' review of the preparation of the
Company's financial statements for the period ended June 30, 1998.  The
Purchaser will indemnify and hold harmless the Shareholders from the commission,
fee or claim of any person or entity employed or retained or claiming to be
employed or retained by the Purchaser to bring about, or to represent it in, the
transactions contemplated hereby.  The Shareholders will indemnify and hold
harmless the Purchaser from the commission, fee or claim of any person or entity
employed or retained or claiming to be employed or retained by the Company or
the Shareholders to bring about, or to represent any of them in, the
transactions contemplated hereby, including without limitation, any claims of
Penn/Thatcher Group or Richard W. Thatcher, Jr.

         14.2  Amendment and Modification.  The parties hereto may amend, modify
and supplement this Agreement in such manner as may be agreed upon by them in
writing.

         14.3  Termination.

         14.3.1  Anything to the contrary herein notwithstanding, this Agreement
    may be terminated and the transactions contemplated hereby may be abandoned:

                 (a) by the mutual written consent of all of the parties hereto 
         at any time prior to the Closing Date;

                 (b) by the Purchaser at any time prior to the Closing Date if
         there shall be a pending action or proceeding by or before any court or
         other governmental body which shall seek to restrain, prohibit or
         invalidate the sale of the Shares to the Purchaser or any other
         transaction contemplated hereby, or which if adversely determined would
         reasonably be expected to affect the right of the Purchaser to own,
         operate in their entirety or control the Shares and the properties and
         assets of the Company and which, in the reasonable judgment of the
         Purchaser, makes it inadvisable to proceed with the transactions
         contemplated by this Agreement;

                 (c) by Purchaser in the event of the material breach by Company
         or any Shareholder of any provision of this Agreement, which breach is
         not remedied by the breaching party within 30 days after receipt of
         written notice of such breach from the Purchaser;

                 (d) by the Shareholders' Representative (on behalf of himself,
         the other Shareholders and the Company) in the event of a material
         breach by Purchaser of any provision of this Agreement, which breach is
         not remedied by Purchaser within thirty (30) days after receipt of
         written notice of such breach from the Shareholders' Representative;

                                      -45-
<PAGE>
 
                 (e) by the Shareholders' Representative (on behalf of himself,
         the other Shareholders and Company) at any time prior to the Closing
         Date if there shall be a pending action or proceeding by or before any
         court or other governmental body which shall seek to restrain, prohibit
         or invalidate the sale of the Shares to the Purchaser or any other
         transaction contemplated hereby, or which if adversely determined would
         reasonably be expected to affect the right or ability of the
         Shareholders to sell the Shares and which, in the reasonable judgment
         of the Shareholders' Representative, makes it inadvisable to proceed
         with the transactions contemplated by this Agreement; or

                 (f) by the Purchaser or the Shareholders' Representative (on
         behalf of himself, the other Shareholders and the Company), if for any
         reason or no reason the transactions contemplated by this Agreement
         have not been consummated on or before August 14, 1998.

    If this Agreement is terminated pursuant to clause (a), (b), (e) or (f) of
    this paragraph 14.3.1, no party shall have any liability for any costs or
    expenses, or any further obligation for breach of warranty or otherwise to
    any other party to this Agreement.  Any termination of this Agreement
    pursuant to clause (c) or (d) of this paragraph 14.3.1 shall be without
    prejudice to any other rights or remedies of the respective parties.  Within
    ten days after any termination of this Agreement, Purchaser shall return to
    the Company and the Shareholders all documents and other written information
    (and all copies thereof, regardless of medium) received by Purchaser, its
    legal counsel, accountants or other representatives in respect of the
    Company, whether received from the Company, any Shareholder or the Company's
    legal counsel, accountants or other representative, and Purchaser shall not
    use or disclose any such information for any purpose at any time after such
    termination.

         14.3.2  The risk of any loss to the properties or assets of the Company
    and all liability with respect to injury and damage occurring in connection
    therewith shall be the sole responsibility of the Company and the
    Shareholders until the completion of the Closing.  If any material part of
    said properties and assets shall be damaged by fire or other casualty prior
    to the completion of the Closing hereunder, the Company and the Shareholders
    shall so notify the Purchaser and the Purchaser shall have the right and
    option:

               (a) to terminate this Agreement, without liability to any party
         hereto; or

               (b) to proceed with the Closing hereunder, in which event such
         casualty shall not constitute a breach by the Company or the
         Shareholders of any representation, warranty or covenant in this
         Agreement, and the Purchaser shall be entitled to receive and retain
         the insurance proceeds arising from such casualty.

                        ALLIN COMMUNICATIONS CORPORATION


                 _____________________________________________

     Allin Communications Corporation, a corporation organized and existing by
virtue of the laws of the State of Delaware (the "Corporation"), does hereby
certify that the following resolutions were duly adopted by the Board of
Directors of the Corporation on August 6, 1998.

     RESOLVED THAT, pursuant to the authority expressly granted to and vested in
the Board of Directors of the Corporation by the provisions of the Certificate
of Incorporation of the Corporation (the "Certificate of Incorporation"), the
Board of Directors hereby creates, from the shares of Preferred Stock (the
"Preferred Stock") of the Corporation authorized to be issued pursuant to the
Certificate of Incorporation, a series of the Preferred Stock designated Series
B Redeemable Preferred Stock, and hereby fixes the voting powers, designations,
preferences and relative participating, optional or other rights, and the
qualifications, limitations or restrictions thereof, of the shares of such
Series as follows:

     1.   Designation.  Five thousand (5,000) shares of the Preferred Stock are
          -----------                                                          
hereby designated Series B Redeemable Preferred Stock with a par value of $.01
per share (the "Series B Preferred Stock").

     2.   Rank.  The Series B Preferred Stock shall rank senior to the Common
          ----                                                               
Stock and the Series A Convertible Redeemable Preferred Stock.

     3.   Dividends.
          --------- 

          (a) The holders of shares of Series B Preferred Stock shall be
entitled to receive, when and as declared out of funds legally available for the
payment of dividends by the Board of Directors, cash dividends on each share of
the Series B Preferred Stock (referred to as a "Share") at a rate per annum of
6% of the Liquidation Value thereof, from
<PAGE>
 
and including the date of issuance of such Share to and including the date on
which the Redemption Price of such Share is paid.

          Such dividends, to the extent declared by the Board of Directors, will
be payable quarterly in arrears on each October 31, January 31, April 30 and
July 31 (hereinafter referred to as "Dividend Payment Dates").  To the extent
that dividends are not paid on a particular Dividend Payment Date, all such
dividends will accrue and compound on a quarterly basis and will be paid on or
before the Redemption Date.

          (b) So long as any shares of the Series B Preferred Stock are
outstanding, the Corporation will not declare or pay or set apart for payment
any dividends (other than a dividend in common stock or in any other class of
stock ranking junior to the Series B Preferred Stock as to dividends and upon
liquidation) or make any other distribution on any class of stock of the
Corporation ranking junior to the Series B Preferred Stock either as to
dividends or upon liquidation (collectively, "Junior Securities") and will not
redeem, purchase or otherwise acquire for value, or set apart money for any
sinking or other analogous fund for the redemption or purchase of any shares of
any Junior Securities (in any such case, a "Junior Payment"), unless all
dividends on the Series B Preferred Stock for the Dividend Payment Date
immediately prior to or concurrent with the payment with respect to any such
dividend, distribution, redemption, purchase or acquisition as to such Junior
Securities shall have been paid, or declared and a sum sufficient for the
payment thereof set aside by the Corporation separate and apart from its other
funds.

     4.   Liquidation.
          ----------- 

          (a) In the event of any voluntary or involuntary liquidation,
dissolution or winding up of the Corporation, before any payment or distribution
of the assets of the Corporation (whether capital, surplus or earnings) or
proceeds therefrom shall be made to or set apart for the holders of shares of
any Junior Securities, the holders of shares of Series B Preferred Stock shall
be entitled to receive payment of $1,000 per share (the "Liquidation Value")
held by them, plus an amount equal to all dividends accrued and compounded and
unpaid on such shares to the date of such payment.

          (b) If upon any liquidation, dissolution or winding up of the
Corporation, the Corporation's assets to be distributed among the holders of the
Series B Preferred Stock are insufficient to permit payment to such holders of
the aggregate amount which they are entitled to be paid, then the entire assets
to be distributed will be distributed ratably among such holders based upon the
aggregate Liquidation Value of the Series B Preferred Stock held by each such
holder.  The Corporation will mail written notice of such liquidation,
dissolution or winding up, not less than sixty (60) days prior to the payment
date stated therein, to each record holder of Series B Preferred Stock.  Neither
the consolidation nor merger of the Corporation into or with any other
corporation or corporations, nor the sale or transfer by the Corporation of all
or any part of its assets, nor the reduction of the capital

                                      -2-
<PAGE>
 
stock of the Corporation, will be deemed to be a liquidation, dissolution or
winding up of the Corporation within the meaning of this paragraph.

     5.   Redemption.
          ---------- 

          (a) Mandatory Redemption at December 31, 1998.  In the event that the
              -----------------------------------------                        
holders of the Corporation's common stock have not approved the issuance of
common stock pursuant to the conversion rights set forth in paragraph 7 hereof

shares of Series B Preferred Stock (subject to the legal availability of funds
therefor) on or before December 31, 1998.

          (b) Mandatory Redemption after Five Years.  In the event that the
              -------------------------------------                        
holders of the Corporation's common stock have approved the issuance of common
stock pursuant to the conversion rights set forth in paragraph 7 hereof on or

Series B Preferred Stock (subject to the legal availability of funds therefor)
on or before the fifth anniversary of the date of original issuance of the
Series B Preferred Stock (the "Maturity Redemption Date").

          (c) Mandatory Redemption upon Sale of Assets.  In the event that the
              ----------------------------------------                        
Corporation consummates an Asset Sale prior to the Maturity Redemption Date, at
the option of the holders of the Series B Preferred Stock, the Corporation shall
redeem all outstanding shares of Series B Preferred Stock (subject to the legal
availability of funds therefor) on or before the date which is five (5) business
days following consummation of the Asset Sale.  For purposes of this paragraph
"Asset Sale" shall mean any sale, issuance, conveyance, transfer, lease or other
disposition (including, without limitation, by way of merger, consolidation or
sale and leaseback transaction) (collectively, a "Transfer") by the Corporation
or its subsidiaries, directly or indirectly, in one or a series of related
transactions, to any person other than the Corporation or any of its
subsidiaries, which Transfer results in net proceeds to the Corporation and its
subsidiaries in an aggregate amount sufficient to repay all then outstanding
debt of the Corporation and its subsidiaries and to pay the Redemption Price.

          (d) Redemption Price.  The redemption price for shares of Series B
              ----------------                                              
Preferred Stock shall be One Thousand Dollars ($1,000) per Share, plus an amount
equal to all accrued and compounded and unpaid dividends to the date of
redemption (the "Redemption Price").

          (e) Redemption Procedure.  Unless default is made in the payment of
              --------------------                                           
the Redemption Price, all rights of the holders of such Shares as stockholders
of the Corporation by reason of the ownership of the respective Shares shall
cease at the close of business on the Redemption Date ("Redemption Date"),
except the right to receive payment in full of the Redemption Price of such
Shares on presentation and surrender of the certificate or certificates for such
Shares, and after the Redemption Date such Shares shall not be deemed to be
outstanding.  In case less than all the Shares represented by any such
certificate are

                                      -3-
<PAGE>
 
redeemed, a new certificate shall be issued representing the unredeemed Shares
without cost to the holder thereof.

          At its option, the Corporation may, on or prior to the Redemption
Date, deposit an amount equal to the aggregate Redemption Price of the Shares of
the Series B Preferred Stock to be redeemed with a bank or trust company (the
"Depositary"), having its principal office in the City of Pittsburgh,
Commonwealth of Pennsylvania, and designated by the Board of Directors, to be
held in trust by the Depositary, for the sole benefit of the holders of the
Series B Preferred Stock, for payment to the holders of such Shares then to be
redeemed.  If such deposit is made and the funds so deposited are made
immediately available to the holders of the Shares of the Series B Preferred
Stock to be redeemed, the Corporation shall thereupon be released and discharged
(subject to the provisions of the next paragraph of this Section) from its
obligation to make payment of the Redemption Price of the Shares of Series B
Preferred Stock to be redeemed, and the holders of such Shares shall look only
to the Depositary for such payment.

          Any funds deposited with the Depositary as aforesaid with respect to
payment of the Redemption Price of Shares of the Series B Preferred Stock
remaining unclaimed at the end of five (5) years from and after the Redemption
Date in respect of which such funds were deposited, shall be returned to the
Corporation forthwith; and thereafter the holders of Shares of the Series B
Preferred Stock redeemed on such Redemption Date shall look only to the
Corporation for the payment of the Redemption Price thereof.  Any interest
accrued on any funds deposited with the Depositary shall belong to the
Corporation and shall be paid to it by the Depositary from time to time on
demand.

          On or after the Redemption Date, the holders of Shares of Series B
Preferred Stock which have been redeemed shall surrender their certificates
representing such Shares to the Corporation at its principal place of business
or as otherwise notified, and thereupon the Redemption Price of such Shares
shall be paid to the order of the holder of record of the Shares represented by
such certificate or certificates and each surrendered certificate shall be
cancelled, and such Shares shall be retired and shall not be reissued.

     6.   Voting.  Except as otherwise provided by the Delaware General
          ------                                                       
Corporation Law and in this Section, the holders of Series B Preferred Stock
shall have no voting rights whatsoever.  Without the consent of the holders of
at least a majority of the number of shares of Series B Preferred Stock at the
time outstanding and eligible to vote, given in person or by proxy, either in
writing or at a meeting called for the purpose at which the holders of Series B
Preferred Stock shall vote as a class, neither the Certificate of Incorporation
nor the Certificate of Designation relating to the Series B Preferred Stock
shall be changed, nor shall the Board of Directors take any action, so as to
affect adversely the rights and preferences of the Series B Preferred Stock as
set forth herein.

     7.   Conversion.
          ---------- 

          (a) Conversion Rights.  Upon approval by the holders of the
              -----------------                                       
Corporation's common stock of the issuance of shares of common stock in
accordance with this paragraph 7, each holder of the Series B Preferred Stock
will have the right to convert all or a portion of its Shares of Series B
Preferred Stock into common stock of the Corporation in accordance with this

first anniversary of the original issuance of shares of Series B Preferred
Stock, each share of Series B Preferred Stock held by each holder may be
converted into the number of common shares, rounded to the ninth decimal place,
determined by (i) dividing 1,000 by 85% of the closing price of the common stock
as reported by The Nasdaq Stock Market on the trading date immediately preceding
the date of original issuance of shares of Series B Preferred Stock, or (ii) if
it results in a greater number of shares of common stock, dividing 1,000 by the
greater of (A) 85% of the closing price of the common stock as reported by The
Nasdaq Stock Market on the trading date prior to the date of the conversion or
(B) $2.00.  After the first anniversary of the original issuance of shares of
Series B Preferred Stock, each share of Series B Preferred Stock held by each
holder may be converted into the number of common shares, rounded to the ninth
decimal place, determined by (i) dividing 1,000 by 85% of the closing price of
the common stock as reported by The Nasdaq Stock Market on the trading date
immediately preceding the date of original issuance of shares of Series B
Preferred Stock, or (ii) if it results in a greater number of shares of common

Holders of the Series B Preferred Stock who exercise the foregoing conversion
right shall have the right to receive any accrued, but unpaid dividends.  No
fractional shares of common stock shall be issued; instead a cash payment will
be made in lieu of the issuance of any fractional shares of common stock.  Any
shares of Series B Preferred Stock which are not converted to common stock will
remain outstanding until so converted or until redeemed by the Corporation.  In
the event that the number of shares of outstanding common stock is changed by
any stock dividend, stock split or combination of shares at any time shares of
Series B Preferred Stock are outstanding, the number of shares of common stock
that may be acquired upon conversion of such outstanding Series B Preferred
Stock in accordance with the foregoing shall be proportionately adjusted.

          (b) Conversion Procedures.  Any holder of Series B Preferred Stock
              ---------------------                                         
wishing to exercise the foregoing conversion right shall give written notice
thereof to the Corporation (the "Conversion Notice").  Upon receipt of the
Conversion Notice, the Corporation shall set a date for the conversion of the
Series B Preferred Stock, which date shall be not more than thirty (30) days
from the date of the Conversion Notice (the "Conversion Date").  All rights of a
holder of the Series B Preferred Stock as a preferred stockholder of the
Corporation by reason of the ownership of Series B Preferred Shares being
converted shall cease at the close of business on the Conversion Date, except
the right to receive, on presentation and surrender of the certificate or
certificates for the Series B Preferred Stock being converted, the shares of
common stock into which the Series B

for each share of common stock held by such holder or that such holder is
entitled to receive upon presentation and surrender of certificates for shares
of Series B Preferred Stock as provided for in the preceding sentence, but such

                                       OF
                        ALLIN COMMUNICATIONS CORPORATION

     It is hereby certified that:

     1.  The name of the corporation (hereinafter called the "corporation") is
Allin Communications Corporation.

     2.  The Certificate of Designations of the Series B Redeemable Preferred
Stock of the Corporation, which was filed with the Secretary of State of
Delaware on August 12, 1998, is hereby corrected.

     3.  The defect to be corrected in said instrument is as follows:

          The description of the conversion formula to be used after the first
          anniversary of the original issuance of shares of Series B Preferred
          Stock omits the words "85% of" in the clause reading "or (ii) if it
          results in a greater number of shares of common stock, dividing 1,000
          by the closing price of the common stock as reported by The Nasdaq
          Stock Market on the first trading date following the first anniversary
          of the original issuance of shares of Series B Preferred Stock."

          The foregoing phrase should read as follows: "or (ii) if it results in
          a greater number of shares of common stock, dividing 1,000 by 85% of
          the closing price of the common stock as reported by The Nasdaq Stock
          Market on the first trading date following the first anniversary of
          the original issuance of shares of Series B Preferred Stock."

     4.   Section 7(a) of the Certificate of Designations of the Series B
Redeemable Preferred Stock of the Corporation is as follows:

          (a) Conversion Rights.  Upon approval by the holders of the
              -----------------                                       
          Corporation's common stock of the issuance of shares of common stock
          in accordance with this paragraph 7, each holder of the Series B
          Preferred Stock will have the right to convert all or a portion of its
          Shares of Series B Preferred Stock into common stock of the
          Corporation in accordance with this paragraph 7 at any time prior to
          the Redemption Date.  Until and including the first anniversary of the
          original issuance of shares of Series B Preferred Stock, each share of
          Series B Preferred Stock held by each holder may be converted into the
          number of common shares, rounded to the ninth decimal place,
          determined by (i) dividing 1,000 by 85% of the closing price of
<PAGE>
 
          the common stock as reported by The Nasdaq Stock Market on the trading
          date immediately preceding the date of original issuance of shares of
          Series B Preferred Stock, or (ii) if it results in a greater number of
          shares of common stock, dividing 1,000 by the greater of (A) 85% of
          the closing price of the common stock as reported by The Nasdaq Stock
          Market on the trading date prior to the date of the conversion or (B)
          $2.00.  After the first anniversary of the original issuance of shares
          of Series B Preferred Stock, each share of Series B Preferred Stock
          held by each holder may be converted into the number of common shares,
          rounded to the ninth decimal place, determined by (i) dividing 1,000
          by 85% of the closing price of the common stock as reported by The
          Nasdaq Stock Market on the trading date immediately preceding the date
          of original issuance of shares of Series B Preferred Stock, or (ii) if
          it results in a greater number of shares of common stock, dividing
          1,000 by 85% of the closing price of the common stock as reported by
          The Nasdaq Stock Market on the first trading date following the first
          anniversary of the original issuance of shares of Series B Preferred
          Stock.  Holders of the Series B Preferred Stock who exercise the
          foregoing conversion right shall have the right to receive any
          accrued, but unpaid dividends.  No fractional shares of common stock
          shall be issued; instead a cash payment will be made in lieu of the
          issuance of any fractional shares of common stock.  Any shares of
          Series B Preferred Stock which are not converted to common stock will
          remain outstanding until so converted or until redeemed by the
          Corporation.  In the event that the number of shares of outstanding
          common stock is changed by any stock dividend, stock split or
          combination of shares at any time shares of Series B Preferred Stock
          are outstanding, the number of shares of common stock that may be
          acquired upon conversion of such outstanding Series B Preferred Stock
          in accordance with the foregoing shall be proportionately adjusted.

     Signed on August 13, 1998.

                                   ARTICLE II
                               PREEMPTIVE RIGHTS

          2.1  Grant of Rights.  If at any time following the date hereof the
Company proposes to sell any shares of Capital Stock or Capital Stock
Equivalents, the Company will first offer to each Subscriber the right to
purchase up to the number of shares of Capital Stock (or in the case of a sale
of Capital Stock Equivalents, such Capital Stock Equivalents whose Underlying
Shares are) equal to the product of (a) the number of shares of Capital Stock
(or Underlying Shares with respect to the Capital Stock Equivalents) proposed to
be sold by the Company multiplied by (b) a fraction, the numerator of which is
the number of shares of Series B Preferred Stock purchased by the Subscriber on
the date hereof and the denominator of which is the total number of shares of
Series B Preferred Stock issued as of the date hereof, for the same price and on
the same economic terms as the securities are being offered in such transaction.
If noncash consideration is proposed to be received for the securities, the
price for purposes of the preceding sentence shall be the sum of any cash to be
received plus the fair market value of the noncash property to be received, as
determined in good faith by the Board.

          2.2  Notice to Subscribers.  The Company will cause to be given to
each Subscriber a written notice directed to each Subscriber setting forth a
description of the securities being offered, the price and other economic terms
at which the Subscriber may purchase such securities and the calculation made as
to the number of securities that the Subscriber has the right to purchase,
whereupon the Subscriber shall have a period of two (2) business days from the
date such notice is given to give written notice to the Company that he or it
desires to exercise his or its right to purchase the securities.  Capital Stock
or any Capital Stock Equivalents which have been offered in accordance with this
Article II to each Subscriber and with respect to which, within the applicable
period specified above, a Subscriber has not given notice to the Company that he
or it desires to exercise its right to purchase, may thereafter, for a period
not exceeding three months following the expiration of such period, be issued,
sold or subjected to rights or options to any other Person at a price not less
than that at which they were offered to the declining Subscriber.  Any such
securities not so issued, sold or subjected to rights or options to others
during such three-month period will thereafter again be subject to the first
refusal rights provided for in this Article II.

          2.3  Exceptions.  Anything in this Agreement to the contrary
notwithstanding, the provisions of this Article II shall not be applicable to
(i) the granting of options or the issuance of Capital Stock pursuant to an
Approved Stock Plan, (ii) the issuance of the Series B Preferred Stock and the
Warrants pursuant the Subscription Agreements, (iii) the issuance of Capital
Stock pursuant to the declaration or payment of any dividend on the Capital
Stock payable in shares of Capital Stock, (iv) the issuance of Capital Stock to
a seller as consideration for the purchase of equity interests or assets of an
entity unaffiliated with the Company whether pursuant to a merger or otherwise,
(v) the issuance of Underlying Shares or (vi) securities offered to all holders
of a particular class of outstanding Capital Stock on a pro rata basis whether
pursuant to an exchange offer or otherwise.

          2.4  Termination of Preemptive Rights.  Anything in this Agreement to
the contrary notwithstanding, the provisions of this Article II shall terminate
and be of no force or effect on the earliest of (i) the first anniversary of the
date hereof or (ii) with respect to any particular Subscriber, such time as such
Subscriber shall have declined to exercise his or its preemptive rights in
connection with two separate and distinct proposed sales, with respect to which
(a) the Subscriber received notices in accordance with Section 2.2 and (b) the
Company actually sold securities to other Persons in accordance with the terms
set forth in such notices and in accordance with this Article II.


                                  ARTICLE III

THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 OR

VOID AFTER 5:00 p.m., Pittsburgh, Pennsylvania Time, on the earlier of December
31, 1998 if all outstanding shares of Series B Preferred Stock of Allin

                                 Warrant to Purchase __________
                                 Shares of Common Stock


                        WARRANT TO PURCHASE COMMON STOCK

                                       OF

                        ALLIN COMMUNICATIONS CORPORATION


         This is to certify that, for valuable consideration, receipt of which
is hereby acknowledged, ________________________________________________ (the
"Holder"), is entitled to purchase, subject to the provisions of this Warrant,
from ALLIN COMMUNICATIONS CORPORATION, a Delaware corporation (the "Company"),
__________ fully paid and nonassessable shares of the Common Stock, $.01 par
value per share, of the Company (the "Stock"), subject to adjustment as
hereinafter set forth, at such price, during such period and subject to such
terms as hereinafter set forth.  Unless the context otherwise requires, the term
"Warrant" or "Warrants" as used herein includes this Warrant and any other
Warrant or Warrants which may be issued pursuant to the provisions of this
Warrant, whether upon transfer, assignment, partial exercise, divisions,
combinations, exchange or otherwise, and the term "Holder" includes any
transferee or transferees or assignee or assignees of the Holder named above,
all of whom shall be subject to the provisions of this Warrant, and, when used
with reference to shares of Stock, means the holder or holders of such shares of
Stock.  This Warrant is issued pursuant to the terms of
<PAGE>
 
that certain Subscription Agreement dated as of August __, 1998 between the
original Holder and the Company.

         Section 1. Exercise Price.  Subject to the provisions with respect to
adjustment in Section 7, the purchase price for each share of Stock purchasable
pursuant hereto shall be $4.25 per share (hereinafter, as adjusted from time to
time as herein required, the "Exercise Price").

         Section 2. Exercise of Warrant.

         (a) This Warrant may only be exercised pursuant to this Section 2 from
and after the date on which the holders of the outstanding Stock approve the
issuance of Stock upon exercise pursuant to this Section 2.

         (b) This Warrant may be exercised, in whole or in part at any time or
from time to time, on or prior to 5:00 p.m., Pittsburgh, Pennsylvania time, on
the earlier to occur of (i) December 31, 1998 if all outstanding shares of
Series B Preferred Stock of the Company are required to be redeemed by the
Company as of such date or (ii) August 13, 2003, or if such date is a day on
which federal or state chartered banking institutions located in the
Commonwealth of Pennsylvania are authorized by law to close, then on the next
succeeding day which shall not be such a day, by presentation and surrender to
the Company at its principal office in Pennsylvania of this Warrant and the
purchase form annexed hereto duly executed and accompanied by payment, in cash,
certified or cashier's check payable to the order of the Company or shares of
Series A Convertible Redeemable Preferred Stock of the Company ("Series A
Preferred Stock"), of the Exercise Price for the number of shares of Stock to be
purchased upon exercise of the Warrant.  If payment is made by delivery of
shares of Series A Preferred Stock, the number of shares of Series A Preferred
Stock so delivered must have an aggregate liquidation value plus accrued and
unpaid dividends, if any, equal to the exercise price for the number of shares
of Stock to be purchased upon exercise of the Warrant.  If this Warrant is
exercised in part only, the Company shall, promptly after presentation of this
Warrant upon such exercise, execute and deliver a new Warrant evidencing the
rights of the Holder hereof to purchase the unexercised balance of this Warrant.
Upon and as of such receipt of this Warrant and the purchase form by the Company
at its principal office in Pennsylvania, in proper form for exercise and
accompanied by payment as herein provided, the Holder shall be deemed to be the
holder of record of the shares of Stock issuable upon such exercise,
notwithstanding that the stock transfer books of the Company shall then be
closed or that certificates representing such shares of Stock shall not then be
actually delivered to the Holder.

         Section 3. Covenants of Company.  The Company represents, warrants,
covenants and agrees as follows:

         (a) All Shares which may be issued upon the exercise of the rights
represented by this Warrant will, upon issuance in accordance with the
provisions of this

                                      -2-
<PAGE>
 
Warrant, be duly and validly issued, fully paid and nonassessable and free from
all taxes, liens and charges with respect to the issuance thereof (other than
taxes in respect of any transfer occurring contemporaneously with such
issuance).

         (b) The Company will at all times until expiration of this Warrant
reserve and keep available, free from preemptive rights, out of its authorized
but unissued capital stock (or capital stock held in treasury), a number of
shares of Stock equal to the total number of shares of Stock issuable upon
exercise of this Warrant.

         (c) The Company acknowledges and agrees that, pursuant to a
Registration Rights Agreement dated the date hereof among the Company, the
Holder and other holders of warrants, the Holder has certain registration rights
with respect to the shares of Stock issuable upon exercise of this Warrant.

         Section 4. Fractional Shares.  No fractional shares of Stock or scrip
representing fractional shares shall be issued upon the exercise of this
Warrant.  In lieu of any fractional shares to which the Holder would otherwise
be entitled upon exercise hereof, the Company shall pay to the Holder an amount
in cash equal to such fraction multiplied by the Exercise Price.

         Section 5. Transfer, Exchange, Assignment or Loss of Warrant.

         5.1   This Warrant may not be assigned or transferred except as
provided in this Section 5 and in accordance with and subject to the provisions
of the Securities Act of 1933, as amended, and the Rules and Regulations
promulgated thereunder (said Act and such Rules and Regulations being
hereinafter collectively referred to as the "Act").  Any purported transfer or
assignment made other than in accordance with this Section 5 shall be null and
void and of no force and effect.

         5.2   Prior to any transfer of this Warrant, other than in an offering
registered under the Act, the Holder shall notify the Company in writing of its
intention to effect such transfer, indicating the circumstances of the proposed
transfer and furnish the Company with an opinion of its counsel, which counsel
and opinion shall be reasonably satisfactory to the Company, to the effect that
the proposed transfer may be made without registration under the Act or
registration or qualification under any applicable state securities laws.  The
Company will promptly notify the Holder if the opinion of counsel furnished to
the Company is reasonably satisfactory to the Company.  Unless the Company
notifies the Holder within 10 business days after its receipt of such opinion
that such opinion is not reasonably satisfactory to counsel for the Company, the
Holder may proceed to effect the transfer.

         5.3   Each certificate for shares of Stock or for any other security
issued or issuable upon exercise of this Warrant shall contain the following
legend (unless the

                                      -3-
<PAGE>
 
Company shall have received an opinion of counsel reasonably satisfactory to it
that such legend is not required to assure compliance with the Act):

         THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
         1933 OR SECURITIES LAWS OF ANY STATE, HAVE BEEN ACQUIRED FOR INVESTMENT
         AND NOT WITH A VIEW TO OR FOR SALE IN CONNECTION WITH ANY DISTRIBUTION
         AND MAY NOT BE SOLD OR OTHERWISE TRANSFERRED UNLESS REGISTERED PURSUANT
         TO APPLICABLE PROVISIONS OF FEDERAL AND STATE SECURITIES LAWS OR EXEMPT
         FROM THE REGISTRATION REQUIREMENTS THEREOF.

         The Holder, by accepting this Warrant, agrees and represents that,
unless the shares of Stock to be issued to such Holder upon exercise hereof
shall have been registered under the Act prior to the delivery thereof to such
Holder, it will acquire such shares for investment and not with a view to their
distribution.

         5.4   Any assignment permitted hereunder shall be made by surrender of
this Warrant to the Company at its principal office in Pennsylvania with the
assignment form annexed hereto duly completed and executed.  In such event the
Company shall, without charge for any issuance or transfer tax or other costs
incurred by the Company with respect to such transfer, execute and deliver a new
Warrant in the name of the assignee named in such instrument of assignment and
this Warrant shall promptly be cancelled.  This Warrant may be divided or
combined with other Warrants which carry the same rights upon presentation
thereof at the principal office of the Company in Pennsylvania together with a
written notice signed by the Holder thereof, specifying the names and
denominations in which new Warrants are to be issued.

         5.5   Upon receipt by the Company of evidence satisfactory to it of the
loss, theft, destruction or mutilation of this Warrant (provided that an
affidavit of the Holder shall be satisfactory for such purpose), and of
indemnity satisfactory to it and upon surrender and cancellation of this
Warrant, if mutilated, the Company will execute and deliver a new Warrant of
like tenor and date and any such lost, stolen or destroyed Warrant shall
thereupon become void.

         Section 6. Rights of Holder.  Any Holder of this Warrant shall not, by
virtue hereof, be entitled to any rights of a stockholder in the Company, either
at law or in equity, and the rights of any such Holder are limited to those
expressed in this Warrant and are not enforceable against the Company except to
the extent set forth herein.

         Section 7.  Adjustment in the Number of Warrant Shares Purchasable and
Exercise Price.

         7.1   The number of shares of Stock or other securities or property for
which this Warrant may be exercised and the Exercise Price shall be subject to
adjustments as follows:

         (a) If the Company, at any time or from time to time, effects a
subdivision or combination, by stock split, reverse stock split or otherwise, of
its outstanding shares of Stock into a larger or smaller number of shares of
Stock, the number of shares of Stock for which this Warrant may be exercised
immediately prior to such subdivision or combination shall be increased or
reduced in the same proportion as the increase or decrease in the outstanding
shares of Stock and the then applicable Exercise Price shall be adjusted by
multiplying such Exercise Price by a fraction, the numerator of which shall be
the number of shares of Stock purchasable upon exercise hereof immediately prior
to such subdivision or combination and the denominator of which shall be the
number of shares of Stock purchasable immediately following such subdivision or
combination.  Any adjustment under this Paragraph (a) shall become effective at
the close of business on the date the subdivision or combination becomes
effective.

         (b) If the Company, at any time or from time to time, declares a
dividend on Stock payable in Stock or securities convertible into Stock the
number of shares of Stock for which this Warrant may be exercised shall be
increased, as of the close of business on the record date for determining which
holders of Stock shall be entitled to receive such dividend, in proportion to
the increase in the number of outstanding shares of Stock as a result of such
dividend (treating for this purpose any securities convertible into Stock as so
converted) and the then applicable Exercise Price shall be adjusted by
multiplying such Exercise Price by a fraction, the numerator of which shall be
the number of shares of Stock purchasable upon exercise hereof immediately prior
to the record date for such dividend and the denominator of which shall be the
number of shares of Stock purchasable immediately following the record date for
such dividend (treating for this purpose any securities convertible into Stock
as so converted).

         (c) If the Company at any time or from time to time makes, or fixes a
record date for the determination of holders of Stock entitled to receive, a
dividend or other distribution payable in securities of the Company other than
shares of Stock or securities convertible into Stock, then and in each such
event provision shall be made so that the Holder shall receive upon exercise
hereof, in addition to the number of shares of Stock receivable thereupon, the
amount of securities of the Company which it would have received had this
Warrant been exercised on the date of such event and had it thereafter, during
the period from the date of such event to and including the date of exercise,
retained such securities receivable by it as aforesaid during such period,
subject to all other adjustments called for during such period under this
Section 7 with respect to the right of the Holder.

                                      -5-
<PAGE>
 
         (d) If the Stock issuable upon the exercise of this Warrant is changed
into the same or a different number of shares of any class or classes of stock
of the Company or property, whether by recapitalization, reclassification or
other exchange (other than a subdivision or combination of shares, or a stock
dividend, or a reorganization, merger, consolidation or sale of assets provided
for elsewhere in this Section 7), then and any in such event the Holder shall
have the right thereafter to purchase the kind and amount of stock and other
securities and property receivable upon such recapitalization, reclassification
or other exchange by holders of the number of shares of Stock with respect to
which this Warrant might have been exercised immediately prior to such
recapitalization, reclassification or other exchange, all subject to further
adjustments as provided herein.

         (e) If at any time or from time to time there is a capital
reorganization of the Stock (other than a subdivision or combination of shares
or a stock dividend or recapitalization, reclassification or exchange of shares
provided for elsewhere in this Section 7) or a consolidation or merger of the
Company with or into another entity or the sale of all or substantially all of
the Company's assets to another person, then, as part of such capital
reorganization, consolidation, merger or sale, provision shall be made so that
the Holder shall thereafter be entitled to receive upon exercise of this Warrant
the same kind and number of shares of Stock and other securities, cash or other
property as would have been distributed to the Holder upon such reorganization,
reclassification, consolidation, merger or sale had the Holder exercised this
Warrant immediately prior to such reorganization, reclassification,
consolidation, merger or sale.  The Holder shall pay upon such exercise the
Exercise Price that otherwise would have been payable pursuant to the terms of
this Warrant.  Appropriate adjustment shall be made in the application of the
provisions of this Section 7 with respect to the rights of the Holder after the
reorganization, consolidation, merger or sale to the end that the provisions of
this Section 7 (including adjustment of the Exercise Price then in effect and
the number of shares or securities deliverable upon exercise of this Warrant)
shall be applicable after that event and shall be nearly equivalent to the
provisions hereof as may be practicable.  If any such reorganization,
reclassification, consolidation, merger or sale results in a cash distribution
in excess of the Exercise Price provided by this Warrant, the Holder may, at the
Holder's option, exercise this Warrant without making payment of the Exercise
Price, and in such case the Company shall, upon distribution to the Holder,
consider the Exercise Price to have been paid in full, and in making settlement
to the Holder, shall deduct an amount equal to the Exercise Price from the
amount payable to the Holder.

         7.2   If the Company shall, other than as provided in Paragraph (e) of
Section 7.1, dissolve, liquidate or wind up its affairs, the Holder shall
thereafter have the right to receive upon proper exercise of this Warrant, in
lieu of the shares of Stock of the Company that the Holder otherwise would have
been entitled to receive, the same kind and amount of securities or assets as
would have been issued, distributed or paid to the Holder upon any such
dissolution, liquidation or winding up with respect to such shares of Stock of
the Company had the Holder been the holder of record of such shares of Stock
receivable

                                      -6-
<PAGE>
 
upon exercise of this Warrant on the date for determining those entitled to
receive any such distribution.

         7.3   In each case of an adjustment or readjustment of the Exercise
Price or the number of shares of Stock or other securities issuable upon
exercise of this Warrant, the Company, at its expense, shall promptly cause
independent public accountants of recognized standing selected by the Company
(who may be the independent public accountants then auditing the books of the
Company) to compute such adjustment or readjustment in accordance with the
provisions hereof and prepare a certificate showing such adjustment or
readjustment, and shall promptly mail such certificate, by first class mail,
postage prepaid, to the Holder at the Holder's address as shown in the Company's
books.  The certificate shall set forth such adjustment or readjustment, showing

$2,000,000.00                                                    August 13, 1998

          FOR VALUE RECEIVED, the undersigned, ALLIN COMMUNICATIONS CORPORATION,
a Delaware corporation, its successors and assigns ("Maker"), hereby promises to
pay to the order of James S. Kelly, Jr., his heirs and assigns ("Lender"), on
the Maturity Date (as such term is defined below), if not sooner paid, the
principal sum of Two Million and 00/100 Dollars ($2,000,000.00) owed to Lender
by the Maker pursuant to that certain Stock Purchase Agreement dated as of the
date of this Note by and among Lender, Maker, KCS Computer Services, Inc.,
Ronald J. Pearce, Joseph J. Kelly and Bradley C. Friedel (the "Agreement"),
together with interest thereon as provided hereinafter.

          Capitalized terms used herein and not otherwise defined herein shall
have the meaning given to such terms in the Agreement.  The unpaid principal
balance hereof shall bear interest for each day until due at the rate of six
percent (6%) per annum and shall accrue and compound quarterly commencing on the
date hereof.  Subject to approval required by a Senior Lender (as hereunder
defined), Maker shall pay such accrued interest to Lender quarterly commencing
on October 1, 1998 and on the first day of each quarter thereafter until such
time as all unpaid principal, accrued interest and all other sums and costs have
been paid in full.  If not sooner paid, all unpaid principal, accrued interest
and all other sums and costs incurred by the Lender (the "Unpaid Amount") shall
be due and payable on the second anniversary of the Closing Date (the "Maturity
Date") without notice, presentment or demand; provided, however, that in the
event that all approvals necessary to convert the Unpaid Amount to Purchaser
Common Stock (as more particularly described in Section 2.1.1(iii) of the
Agreement) have been received by the Maturity Date, the Unpaid Amount
automatically shall convert to Purchaser Common Stock on the Maturity Date on
the terms and conditions set forth in Section 2.1.1(iii) of the Agreement.  In
such event, Maker shall cause the number of shares of Purchaser Common Stock as
required under Section 2.1.1(iii) of the Agreement to be issued to Lender on the
Maturity Date.

          Notwithstanding anything contained herein to the contrary, the payment
of interest and principal hereunder shall be subordinated to, and subject to the
permission of any Lender (the "Senior Lender") which provides (or refinances)
senior financing all or part of which is used initially to pay off (by itself or
combined with funds of Maker) $3,200,000 of indebtedness to Lender evidenced by
that certain Promissory Note in the principal amount of $6,200,000 dated of even
date herewith from Maker to Lender. Maker shall request, but does not guarantee
that it will be able to obtain, a
<PAGE>
 
provision in the documents evidencing such senior financing (the "Senior Loan
Documents") that permits Maker to pay interest hereunder as long as Maker is not
in default under the Senior Loan Documents.

          Principal and interest shall be made payable to Lender and forwarded
to Lender at 100 Trotwood Drive, Monroeville, Pennsylvania 15146, or such other
place as the holder hereof shall designate.

          All payments to be made in respect of principal, interest or other
amounts due from Maker under this Note shall be payable on the day when due
without presentation, demand, protest or notice of any kind, all of which are
hereby expressly waived, and an action therefor shall immediately accrue.

          In connection with this Note, Maker has delivered, or has caused to be
delivered, to Lender the Agreement, that certain Security Agreement of Maker in
favor of Lender dated as of the date of this Note (the "Security Agreement"),
that certain Promissory Note from Maker to Lender dated as of the date of this
Note in the principal sum of $6,200,000 (the "$6,200,000 Note") and that certain
Guaranty and Suretyship Agreement of each of the Guarantors (as defined in the
Security Agreement) in favor of Lender dated the date of this Note (the
"Guaranty", and together with this Note, the Security Agreement, the $6,200,000
Note and all other agreements, documents and instruments in connection
therewith, as each of the foregoing may be amended, modified or supplemented
from time to time, the "Loan Documents").  This Note is secured by, and is
entitled to the benefits of, the Loan Documents.

          Maker shall be in default under this Note upon the occurrence of any
of the following (the "Events of Default"):

          (a) Maker fails to pay any principal or interest due on this Note or
any other amount due and payable under this Note as and when due;

          (b) Maker or Guarantor fails to perform or observe in any material
respect any other material covenant, agreement or duty contained or referred to
herein or in any Loan Document or in Section 2.1.1 (iii) of the Agreement and
such failure continues for a period of thirty (30) consecutive days;

          (c) any material warranty, representation or statement made or
furnished to Lender by or on behalf of Maker in the Stock Purchase Agreement or
any Loan Document proves to have been false or misleading in any material
respect when made or furnished;

          (d) there occurs an Event of Default under the $6,200,000 Note;

                                       2.
<PAGE>
 
          (e) there occurs dissolution, termination of existence, charter
revocation or forfeiture, insolvency, liquidation, reorganization, arrangement,
adjustment, compensation or other similar relief, business failure, assignment
for the benefit of creditors, or the commencement of proceedings under any law
relating to bankruptcy, insolvency, relief of debtors or protection of
creditors, termination of legal entities or any other similar law now or in the
future in effect, or a proceeding shall be instituted in respect of Maker
seeking appointment of a receiver, trustee, custodian, liquidator, assignee,
sequestrator or other similar official for the Maker or for all or any
substantial part of its property by or against Maker or any surety of any of the
obligations of Maker; or

          (f) the Maker shall become insolvent, shall become generally unable to
pay its debts as they become due, shall voluntarily suspend transaction of its
business, shall make a general assignment for the benefit of creditors, shall
institute a proceeding described above or shall consent to any order for relief,
declaration, finding or relief described in (e) above, shall institute a
proceeding described in (e) above or shall consent to the appointment or to the
taking of possession by any such official of all or any substantial part of its
property whether or not any proceeding is instituted, dissolves, winds-up or
liquidates itself or any substantial part of its property, or shall take any
action in furtherance of any of the foregoing.

          Upon the occurrence of any of the Events of Default described in
clauses (a) through (d) above, Lender may declare all liabilities and
obligations of Maker to Lender under the Loan Documents, including those
evidenced by the Note, immediately due and payable and the same shall thereupon
become immediately due and payable without any further action on part of Lender;
provided, however, that if such Event of Default occurs after the Approval Date,
then Lender's sole recourse hereunder shall be (1) to accelerate and immediately
convert the unpaid principal to Purchaser Common Stock, whereupon Maker shall
immediately cause to be issued to Lender such Purchaser Common Stock; (2) to
exercise one of the following options:

          (i)   to accelerate and immediately convert all accrued but unpaid
                interest hereunder as of the conversion date to Purchaser Common
                Stock; or

          (ii)  subject to any required consent of a Senior Lender, to receive
                in cash the amount of the accrued but unpaid interest hereunder
                as of the conversion date; or

          (iii) only in the case of an Event of Default described in clause (a)
                and subject to any required consent of a Senior Lender, to
                receive an amount equal to the amount of interest which would
                have been payable to Lender hereunder if no Event of Default had
                occurred prior to the Maturity Date; such amount to be payable
                quarterly in the same fashion as interest otherwise would have
                been payable hereunder, less all interest actually paid through
                the date of the Event of Default.

Lender shall notify Maker in writing as to which option Lender elects.  Upon the
occurrence of any event of default described in clauses (e) and (f) hereof, all
liabilities and obligations of

                                       3.
<PAGE>
 
Maker to Lender under the Loan Documents, including those evidenced by the Note,
shall immediately become due and payable without any action upon the part of
Lender; provided, however, that if such Event of Default occurs after the
Approval Date, Lender's sole recourse hereunder shall be to (3) accelerate and
immediately convert the unpaid principal to Purchaser Common Stock, whereupon
Maker shall immediately cause to be issued to Lender such Purchaser Common
Stock; and (4) to exercise one of the following options:

          (i)   to accelerate and immediately convert all accrued but unpaid
                interest hereunder as of the conversion date to Purchaser Common
                Stock; or

          (ii)  subject to any required consent of a Senior Lender, to receive
                in cash the amount of the accrued but unpaid interest hereunder
                as of the conversion date; or

          (iii) only in case of an Event of Default described in clause (a) and
                subject to any required consent of a Senior Lender, to receive
                an amount equal to the amount of interest which would have been
                payable to Lender hereunder if no Event of Default had occurred
                prior to the Maturity Date; such amount to be payable quarterly
                in the same fashion as interest otherwise would have been
                payable hereunder, less all interest actually paid through the
                date of the Event of Default.

Lender shall notify Maker in writing as to which option Lender elects.

          Subject to any required consent of any Senior Lender, Maker hereby
consents and agrees that Lender may do any of the following, upon the occurrence
of an Event of Default prior to the Approval Date, as many times as Lender may
agree, desire or permit, without in any way impairing, reducing, limiting,
terminating, or releasing, in whole or in part, the unlimited and continuing
liability of Maker hereunder, without any notice to Maker (all of which notices
are hereby waived by Maker), without incurring any responsibility to Maker, and
without the endorsement or execution by Maker of any additional consent or
waiver.

               (a) settle, compound, collect, liquidate, purchase, postpone,
     compromise, accept partial payment on, or release any Collateral (as
     defined in the Security Agreement) in any manner or subordinate the payment
     of all or any part thereof to the payment of any liability (whether due or
     not) of Maker to its creditors;

               (b) exercise or refrain from exercising any rights, claims or
     demands against, and release or discharge, any maker, endorser, surety,
     guarantor or any other person or entity directly, indirectly, or otherwise
     obligated, including any persons or entities against whom the undersigned 
     may have a right of recourse, regardless of whether rights are 
     specifically reserved against any person or entity not released or 
     discharged; and

                                       4.
<PAGE>
 

               (c) generally act and deal with Maker and the Collateral in any
     manner that Lender may see fit, without notice to any of the undersigned.

          Time is of the essence with respect to the payment of this Note.

          After the principal amount of any part of the loan evidenced by this
Note (the "Loan") shall have become due (at maturity, by acceleration or
otherwise) and before and after judgment, or upon the occurrence of one or more
of the Events of Default, as compensation to the Lender for the increased cost
of administering the Loan, the Loan will bear interest for each day until paid
(before and after judgment) at a rate which will be equal to 10% per annum.

          Interest on the unpaid principal amount hereof shall be computed on
the basis of a 360 day year and the actual number of days elapsed in the period
during which it accrues.

          In the event the rates of interest provided for herein or any of them
are finally determined by any governmental authority to exceed the maximum rate
of interest permitted by applicable usury or similar laws, their or its
application will be suspended and there will be charged instead the maximum rate
of interest permitted by such laws.

          Interest on the Loan will be due and payable on the first day of each
quarter in arrears.  After maturity of any part of the Loan (at maturity, by
acceleration or otherwise), interest on such part of the Loan will be due and
payable on demand.

          All payments to be made in respect of principal, interest, fees or
other amounts due under this Note are payable at 12:00 noon, Pittsburgh time, on
the day when due, without presentment, demand, protest or notice of any kind,
all of which are expressly waived, and an action for the payments will accrue
immediately.  All such payments must be made to the Lender in U.S. dollars and
in funds immediately available, without setoff, counterclaim or other deduction
of any nature.  All such payments shall be applied at the option of the Lender
to late charges, accrued and unpaid interest, outstanding principal and other
sums due under this Note in such order as the Lender, in its sole discretion,
shall elect.

          Maker may prepay any amounts due under this Note, at any time without
premium or penalty.  Payments made hereunder shall be credited first to late
charges, then to lawful charges then accrued and the remainder to principal.

          If this Note is not paid when due and is placed with an attorney for
collection, and whether or not suit is entered hereon or judgment confessed
against the undersigned, the Maker further agrees to pay the holder hereof, in
addition to the principal and accrued interest, the costs of suit and reasonable
attorney's fees.

               ------------ 

          (a)  Shelf Registration.
               ------------------ 

               (i) At any time from the date on which any Conversion Shares may
          be issued until the fifth anniversary of the initial issuance of the
          Series B Preferred Stock and the Warrants, one or more Qualified
          Holders holding in the

                                      -3-
<PAGE>
 
          aggregate at least the number of Conversion Shares equal to ten
          percent of the Conversion Shares that may or have been issued (as
          adjusted for stock splits, stock dividends, reverse stock splits or
          any other combination or division of the Conversion Shares) will be
          entitled to deliver to the Company, on one occasion, a written notice
          (a "Demand") requesting a Shelf Registration.  Upon receipt of a
          Demand, the Company will deliver to each Qualified Holder a written
          notice (the "Notice of Demand") which shall include a copy of the
          Demand together with a statement to the effect that the Company will
          include all Registrable Securities in a Shelf Registration pursuant to
          this Section 2.1(a) unless the Company receives, by a date specified
          in the Notice of Demand (which shall be no less than 20 days following
          the delivery of such Notice of Demand), a notice from a Qualified
          Holder to exclude all or a portion of such Qualified Holder's
          Registrable Securities from such Shelf Registration.  Following
          receipt of a Demand, the Company shall, as expeditiously as reasonably
          possible, use its best efforts to effect a Shelf Registration of all
          Registrable Securities except those which a Qualified Holder has on a
          timely basis requested to be excluded from such Shelf Registration and
          those of any Qualified Holder who does not provide information
          reasonably requested by the Company in connection with the Shelf
          Registration Statement.  The Company may, at its option, include in
          such Shelf Registration Statement shares held by any shareholder other
          than the Qualified Holders having rights similar to those contained in
          this Section 2.1(a).

               (ii) The Company agrees to use its best efforts to keep the Shelf
          Registration Statement continuously effective for a period of two
          years following the date on which such Shelf Registration Statement is
          initially declared effective or such shorter period which will
          terminate when all of the Registrable Securities covered by the Shelf
          Registration Statement have been sold pursuant to the Shelf
          Registration Statement.  The Company further agrees, if necessary, to
          supplement or amend the Shelf Registration Statement, if required by
          the rules, regulations or instructions applicable to the registration
          form used by the Company for such Shelf Registration Statement or by
          the Securities Act or by any other rules and regulations thereunder
          for shelf registration.

               (iii)  On one occasion, the Majority Holders of the Registrable
          Securities covered by a Shelf Registration Statement may elect to have
          such Registrable Securities sold in an Underwritten Offering.  In such
          event, the Company shall be entitled to engage an investment banking
          firm selected by the Company to serve as Underwriter.

          (b)  Piggy-back Registration.
               ----------------------- 

               (i) If the Company at any time prior to the seventh anniversary
          of the original issuance of the Series B Preferred Stock and the
          Warrants proposes to register any of its securities for an
          Underwritten Offering under the Securities Act (other than pursuant to
          a Shelf Registration), whether or not for sale for its own account,
          and if the registration form proposed to be used may be used for the
          registration of Registrable Securities, the Company will each such
          time give prompt written notice to all Qualified Holders of its
          intention to do so.  Upon the written request of any such Qualified
          Holder made within 30 days after the receipt of any such notice (which
          request shall specify the Registrable Securities intended to be
          disposed of by such Qualified Holder), the Company will use its best
          efforts to cause all such Registrable Securities as to which Qualified
          Holders requested registration to be registered under the Securities
          Act (with the securities which the Company at the time proposes to
          register), so as to permit the sale or other disposition by such
          Qualified Holders of such Registrable Securities.

               (ii) No registration effected pursuant to this Section 2.1(b)
          shall be deemed to have been effected pursuant to Section 2.1(a)
          hereof.

               (iii)  Notwithstanding anything to the contrary in this Section
          2.1(b), the Company shall have the right to discontinue any Piggy-back
          Registration at any time prior to the effective date of such Piggy-
          back Registration if the registration of other securities giving rise
          to such Piggy-back Registration is discontinued; but no such
          discontinuation shall preclude an immediate or subsequent request for
          a Shelf Registration.

          (c) Registration Procedures.  If the Company is required by the
              -----------------------                                    
     provisions of this Section 2.1 to use its best efforts to effect or cause
     the registration of any Registrable Securities under the Securities Act as
     provided in this Section, the Company will, as expeditiously as possible:

               (i) prepare and file with the SEC a Registration Statement with
          respect to such Registrable Securities and use its best efforts to
          cause such registration statement to become and remain effective
          during the Applicable Period; in the case of a Shelf Registration
          Statement, such Registration Statement shall be (A) reasonably
          acceptable to special counsel for the Qualified Holders and (B)
          available for the sale of Registrable Securities in accordance with
          the intended method or methods of distribution of the selling
          Qualified Holders (subject to the limitation set forth in Section
          2.1(a)(iii) hereof);

               (ii) prepare and file with the SEC such amendments and
          supplements to such Registration Statement as may be necessary to keep
          such Registration Statement effective for the Applicable Period and to
          comply with the provisions

                                      -5-
<PAGE>
 
          of the Securities Act with respect to the sale or other disposition of
          all securities covered by such Registration Statement during the
          Applicable Period in accordance with the intended methods of
          disposition by the seller or sellers thereof set forth in such
          Registration Statement;

               (iii)  furnish to each seller of such Registrable Securities and,
          in the case of an Underwritten Offering, each Underwriter of the
          securities being sold by such seller, such number of copies of such
          Registration Statement, such number of copies of the Prospectus
          included in such Registration Statement and such other documents as
          such seller and Underwriter may reasonably request in order to
          facilitate the public sale or other disposition of the Registrable
          Securities owned by such seller (including any Prospectus amended or
          supplemented as set forth in Section 2.1(c)(vi));

               (iv) use its best efforts to register or qualify such Registrable
          Securities covered by such Registration Statement under such other
          securities or blue sky laws of such jurisdictions as any seller and
          each Underwriter of the securities being sold by such seller shall
          reasonably request, and do any and all other acts and things which may
          be necessary or advisable to enable such seller and underwriter to
          consummate the disposition in such jurisdictions of such Registrable
          Securities owned by such seller; provided, the Company shall not for
          any such purpose be required to (A) qualify generally to do business
          as a foreign corporation in any jurisdiction wherein it would not but
          for the requirements of this Section 2.1(c)(iv) be obligated to be
          qualified, (B) subject itself to taxation in any such jurisdiction,
          (C) to consent to general service of process in any such
          jurisdictions, or (D) register or qualify such Registrable Securities
          in more than ten states;

               (v) use its best efforts to cause such Registrable Securities
          covered by such registration statement to be registered with or
          approved by such other governmental agencies or authorities as may be
          necessary to enable the seller or sellers thereof to consummate the
          disposition of such Registrable Securities;

               (vi) notify each seller of any such Registrable Securities
          covered by such Registration Statement (i) of the issuance by the SEC
          or any state securities authority of any stop order suspending the
          effectiveness of such Registration Statement or the initiation of any
          proceedings for that purpose, (ii) of receipt of notification with
          respect to the suspension of the qualification of the Registrable
          Securities for offer or sale in any jurisdiction or the initiation of
          any proceeding for such purpose, (iii) at any time when a Prospectus
          relating thereto is required to be delivered under the Securities Act,
          of the Company's becoming aware that the Prospectus included in such
          Registration Statement, as then in effect, includes an untrue
          statement of a material fact or omits to state any material fact
          required to be stated therein or necessary to make the statements
          therein not misleading in

                                      -6-
<PAGE>
 
          the light of the circumstances then existing (other than a fact
          relating to such seller), and promptly use its best efforts to prepare
          a Prospectus supplemented or amended so that, as thereafter delivered
          to the purchasers of such Registrable Securities, such Prospectus
          shall not include an untrue statement of a material fact or omit to
          state a material fact required to be stated therein or necessary to
          make the statements therein not misleading in the light of the
          circumstances then existing;

               (vii)  otherwise use its best efforts to comply with federal and
          state laws and all applicable rules and regulations of the SEC, and
          make available to its security holders, as soon as reasonably
          practicable, an earnings statement which shall satisfy the provisions
          of Section 11(a) of the Securities Act;

               (viii)  use its best efforts (A) to cause all such Registrable
          Securities covered by such Registration Statement to be listed on each
          securities exchange on which similar securities issued by the Company
          are then listed, if the listing of such Registrable Securities is then
          permitted under the rules of such exchange or (B) to secure
          designation of all such Registrable Securities covered by such
          registration statement as a NASDAQ "national market system security"
          within the meaning of Rule 11Aa2-1 under the Exchange Act or, failing
          that, to secure NASDAQ authorization for such Registrable Securities
          and, without limiting the generality of the foregoing, to arrange for
          at least two market makers to register as such with respect to such
          Registrable Securities with the National Association of Securities
          Dealers;

               (ix) provide a transfer agent and registrar for all such
          Registrable Securities covered by such registration statement not
          later than the effective date of such registration statement;

               (x) in the case of an Underwritten Offering, enter into an
          underwriting agreement in customary form and take such other actions
          as Majority Holders shall reasonably request in order to expedite or
          facilitate the disposition of such Registrable Securities;

               (xi) in the case of an Underwritten Offering, use its best
          efforts to obtain an opinion from the Company's counsel and a "cold
          comfort" letter from the Company's independent public accountants in
          customary form and covering such matters of the type customarily
          covered by such opinions and "cold comfort" letters;

               (xii)  make available for inspection by any seller of such
          Registrable Securities covered by such Registration Statement, by any
          Underwriter participating in any disposition to be effected pursuant
          to such Registration Statement and by any attorney, accountant or
          other agent retained by any such

                                      -7-
<PAGE>
 
          seller or any such Underwriter, all pertinent financial and other
          records, pertinent corporate documents and properties of the Company,
          and cause all of the Company's officers, directors and employees to
          supply all information reasonably requested by any such seller,
          underwriter, attorney, accountant or agent in connection with such
          registration statement; provided, however, that all such persons shall
          agree to standard confidentiality provisions regarding all such
          records, documents and information; and

               (xiii)  permit any holder of Registrable Securities which holder,
          in the sole and exclusive judgment, exercised in good faith, of such
          holder, might be deemed to be a controlling person of the Company, to
          participate in the preparation of such registration or comparable
          statement.

     Each Qualified Holder shall be deemed to have agreed by including
     Registrable Securities in a Registration Statement that upon receipt of any
     notice from the Company of the happening of any event of the kind described
     in Section 2.1(c)(vi) hereof, such Qualified Holder will forthwith
     discontinue such Qualified Holder's disposition of Registrable Securities
     pursuant to the Registration Statement covering such Registrable Securities
     until such Qualified Holder's receipt of the copies of the supplemented or
     amended prospectus contemplated by Section 2.1(c)(vi) hereof and, if so
     directed by the Company, will deliver to the Company (at the Company's
     expense) all copies, other than permanent file copies, then in such
     Qualified Holder's possession of the Prospectus covering such Registrable
     Securities current at the time of receipt of such notice.  In the event the
     Company shall give any such notice, the Applicable Period shall be extended
     by the number of days during the period from and including the date of the
     giving of such notice to and including the date when each seller of any
     Registrable Securities covered by such registration statement shall have
     received the copies of the supplemented or amended prospectus contemplated
     by Section 2.1(c)(vi) hereof.

          If any Registration Statement, Prospectus or comparable statement
     refers to any holder by name or otherwise as the holder of any securities
     of the Company, then (whether or not, in the sole and exclusive judgment,
     exercised in good faith, of such holder, such holder is or might be deemed
     to be a controlling person of the Company) such holder shall have the right
     to require (i) the insertion therein of language, in form and substance
     reasonably satisfactory to such holder and presented to the Company in
     writing, to the effect that the holding of such holder of such securities
     is not to be construed as a recommendation by such holder of the investment
     quality of the Company's securities covered thereby and that such holding
     does not imply that such holder will assist in meeting any future financial
     requirements of the Company, or (ii) in the event that such reference to
     such holder by name or otherwise is not required by the Securities Act or
     any similar federal or state statute then in force, the deletion of the
     reference to such holder.  Each seller shall provide to the Company in
     writing information concerning itself required by law to be included in any
     Registration Statement registering shares held by such seller.

         (d) Registration Expenses.  The Company shall, whether or not any Shelf
             ---------------------                                              
     Registration or Piggy-back Registration shall become effective, pay all
     expenses incident to its performance of or compliance with this Section in
     connection with a Shelf Registration or Piggy-back Registration, including
     without limitation all registration and filing fees, fees and expenses of
     compliance with securities or blue sky laws (subject to the limitation set
     forth in Section 2.1(c)(iv) hereof), printing expenses, messenger and
     delivery expenses, fees and disbursements of counsel for the Company and
     all independent public accountants (including the expenses of any audit
     and/or "cold comfort" letter) and other persons retained by the Company and
     reasonable fees and disbursements of one counsel or firm of counsel chosen
     by the Majority Holders, and any fees and disbursements of underwriters
     customarily paid by issuers or sellers of securities (excluding
     underwriting commissions and discounts).  In all cases, any allocation of
     Company personnel or other general overhead expenses of the Company or
     other expenses for the preparation of financial statements or other data
     normally prepared by the Company in the ordinary course of its business
     shall be borne by the Company.

         (e) Indemnification and Contribution.  The Company hereby indemnifies,
             --------------------------------                                  
     to the extent permitted by law, each Qualified Holder, its officers and
     directors, if any, and each Person, if any, who controls such Qualified
     Holder within the meaning of Section 15 of the Securities Act, against all
     losses, claims, damages, liabilities (or proceedings in respect thereof)
     and expenses (under the Securities Act or common law or otherwise), joint
     or several, caused by any untrue statement or alleged untrue statement of a
     material fact contained in any Registration Statement or Prospectus (as
     amended or supplemented if the Company shall have furnished any amendments
     or supplements thereto) or caused by any omission or alleged omission to
     state therein a material fact required to be stated therein or necessary to
     make the statements therein not misleading, except insofar as such losses,
     claims, damages, liabilities (or proceedings in respect thereof) or
     expenses are caused by any untrue statement or alleged untrue statement
     contained in or by any omission or alleged omission from information
     respecting such Qualified Holder furnished in writing to the Company by
     such Qualified Holder expressly for use therein.  If the offering pursuant
     to any Registration Statement provided for under this Section is made
     through Underwriters, the Company agrees to enter into an underwriting
     agreement in customary form with such Underwriters and to indemnify such
     Underwriters, their officers and directors, if any, and each Person, if
     any, who controls such Underwriters within the meaning of Section 15 of the
     Securities Act, against all losses, claims, damages, liabilities (or
     proceedings in respect thereof) and expenses (under the Securities Act or
     common law or otherwise), joint or several, caused by any untrue statement
     or alleged untrue statement of a material fact contained in any
     Registration Statement or Prospectus (as amended or supplemented if the
     Company shall have furnished any amendments or supplements thereto) or
     caused by any omission or alleged omission to state therein a material fact
     required to be stated therein or necessary to make the statements therein
     not misleading, except insofar as such losses, claims, damages, liabilities
     (or proceedings in respect thereof) or expenses are caused by any untrue
     statement or alleged untrue statement contained in or by any omission or
     alleged omission

                                      -9-
<PAGE>
 
     from information respecting such Underwriters or the participating
     Qualified Holders furnished in writing to the Company by such Underwriters
     or the participating Qualified Holders expressly for use therein.  In
     connection with any Registration Statement with respect to Registrable
     Securities held by a Qualified Holder, each such Qualified Holder will
     furnish to the Company in writing such information respecting such
     Qualified Holder as shall be reasonably requested by the Company for use in
     any such Registration Statement or Prospectus and will indemnify, to the
     extent permitted by law, the Company, its officers and directors and each
     Person, if any, who controls the Company within the meaning of Section 15
     of the Securities Act, against any losses, claims, damages, liabilities (or
     proceedings in respect thereof) and expenses resulting from any untrue
     statement or alleged untrue statement of a material fact or any omission or
     alleged omission of a material fact required to be stated in the
     Registration Statement or Prospectus or necessary to make the statements
     therein not misleading, but only to the extent that such untrue statement
     is contained in or such omission is from information so furnished in
     writing by such Qualified Holder expressly for use therein.  If the
     offering pursuant to any such Registration Statement is made through
     Underwriters, each such Qualified Holder agrees to enter into an
     underwriting agreement in customary form with such Underwriters, and to
     indemnify such Underwriters, their officers and directors, if any, and each
     Person, if any, who controls such Underwriters within the meaning of
     Section 15 of the Securities Act to the same extent as hereinbefore
     provided with respect to indemnification by such Qualified Holder of the
     Company.  Any Person entitled to indemnification under the provisions of
     this Section 2.1(e) shall (i) give prompt notice to the indemnifying party
     of any claim with respect to which it seeks indemnification and (ii) unless
     in such indemnified party's reasonable judgment a conflict of interest
     between such indemnified and indemnifying parties may exist in respect of
     such claim, permit such indemnifying party to assume the defense of such
     claim, with counsel reasonably satisfactory to the indemnified party; and
     if such defense is so assumed, such indemnifying party shall not enter into
     any settlement without the consent of the indemnified party if such
     settlement attributes liability to the indemnified party and such
     indemnifying party shall not be subject to any liability for any such
     settlement made without its consent (which consent shall not be
     unreasonably withheld); and any underwriting agreement entered into with
     respect to any Registration Statement provided for under this Section shall
     so provide.  In the event an indemnifying party shall not be entitled, or
     elects not, to assume the defense of a claim, such indemnifying party shall
     not be obligated to pay the fees and expenses of more than one counsel or
     firm of counsel for all parties indemnified by such indemnifying party in
     respect of such claim, unless in the reasonable judgment of any such
     indemnified party a conflict of interest may exist between such indemnified
     party and any other of such indemnified parties in respect to such claim.
     Such indemnity shall remain in full force and effect regardless of any
     investigation made by or on behalf of a participating Qualified Holder, its
     officers, directors or any Person, if any, who controls such Qualified
     Holder as aforesaid, and shall survive the transfer of such securities by
     such Qualified Holder.

                                      -10-
<PAGE>
 
     If for any reason the foregoing indemnity is unavailable, or is
     insufficient to hold harmless an indemnified party, then the indemnifying
     party shall contribute to the amount paid or payable by the indemnified
     party as a result of such losses, claims, damages, liabilities or expenses
     (x) in such proportion as is appropriate to reflect the relative benefits
     received by the indemnifying party on the one hand and the indemnified
     party on the other or (y) if the allocation provided by clause (x) above is
     not permitted by applicable law or provides a lesser sum to the indemnified
     party than the amount hereinafter calculated, in such proportion as is
     appropriate to reflect not only the relative benefits received by the
     indemnifying party on the one hand and the indemnified party on the other
     but also the relative fault of the indemnifying party and the indemnified
     party as well as any other relevant equitable considerations.
     Contributions required to be made by an Underwriter, if any, shall be
     governed by the terms of the underwriting agreement.  Notwithstanding the
     foregoing, no person guilty of fraudulent misrepresentation (within the
     meaning of Section 11(f) of the Securities Act) shall be entitled to
     contribution from any person who was not guilty of such fraudulent
     misrepresentation.

          (f) Certain Limitations on Registration Rights.
              ------------------------------------------ 

               (i) In the case of an Underwritten Offering under a Shelf
          Registration, if the Majority Holders determine to enter into an
          underwriting agreement in connection therewith, or, in the case of a
          Piggy-back Registration, if the Company or holders of securities
          initially requesting or demanding such registration have determined to
          enter into an underwriting agreement in connection therewith, all
          Registrable Securities to be included in such registration shall be
          subject to such underwriting agreement, and no Person may participate
          in such registration unless such Person agrees to sell such Person's
          securities on the basis provided in the underwriting arrangements
          approved by the Company or such holders and completes and/or executes
          all questionnaires, powers of attorney, indemnities, underwriting
          agreements and other reasonable documents which must be executed under
          the terms of such underwriting arrangements.

               (ii) Notwithstanding anything to the contrary in this Section
          2.1, if the Company shall previously have received a request for
          registration under this or any other registration rights agreement,
          and if such previous registrations shall not have been withdrawn or
          abandoned, the Company will not effect any registration of any of its
          securities under the Securities Act (other than a registration on Form
          S-4 or S-8 (or any similar form) or other publicly registered offering
          pursuant to the Securities Act pertaining to the issuance of
          securities under any benefit plan, employee compensation plan, or
          employee or director stock purchase plan or in connection with an
          offer of securities solely to existing security holders) whether or
          not for sale for its own account, until a period of three months shall
          have elapsed from the effective date of such previous

                                      -11-
<PAGE>
 
          registration; and the Company shall so provide in any registration
          rights agreements hereafter entered into with respect to any of its
          securities.

          (g) Allocation of Securities Included in Registration Statement.  In
              -----------------------------------------------------------     
     the case of an Underwritten Offering, if the Company's managing Underwriter
     shall advise the Company and the Qualified Holders in writing that the
     inclusion in any registration pursuant to this Section of some or all of
     the Registrable Securities sought to be registered by the holders
     requesting such registration creates a substantial risk that the proceeds
     or price per unit the Sellers (as defined below) will derive from such
     registration will be reduced or that the number of securities to be
     registered (including those sought to be registered at the instance of the
     Company and any other party entitled to participate in such registration as
     well as those sought to be registered by the Qualified Holders) is too
     large a number to be reasonably sold, then the number of Registrable
     Securities sought to be registered by each Seller shall be reduced pro rata
     in proportion to the number of securities sought to be registered by all
     Sellers to the extent necessary to reduce the number of securities to be
     registered to the number recommended by the managing underwriter.

          For purposes of this Section 2.1(g) the term "Seller" shall mean and
     include the Company and each holder of securities (including, but not
     limited to, Registrable Securities) entitled to participate in the subject
     registration.

          (h) Limitations on Sale or Distribution of Other Securities.  Each
              -------------------------------------------------------       
     holder of Registrable Securities shall be deemed to have agreed by the
     inclusion of Registrable Securities in a Registration Statement not to
     effect any public sale or distribution, including (if requested by the
     Underwriter) any sale pursuant to Rule 144 under the Securities Act, of any
     Registrable Securities, and to use such holder's best efforts not to effect
     any public sale or distribution of any other equity security of the Company
     or of any security convertible into or exchangeable or exercisable for any
     equity security of the Company (other than as part of such underwritten
     public offering) within 7 days before or 90 days (or such other period to
     which the Underwriters of such offering may consent) after the effective
     date of any Registration Statement filed by the Company pursuant to this
     Article II or other agreement providing for registration rights.

          2.2  Rule 144.  The Company covenants that it will timely file the
               --------                                                     
reports required to be filed by it under the Securities Act or the Exchange Act
(including but not limited to the reports under Sections 13 and 15(d) of the
Exchange Act referred to in subparagraph (c)(l) of Rule 144 adopted by the SEC
under the Securities Act) and the rules and regulations adopted by the SEC
thereunder (or, if the Company is not required to file such reports, will, upon
the request of any Qualified Holder, make publicly available such information),
and will take such further action as any Qualified Holder may reasonably
request, all to the extent required from time to time to enable such Qualified
Holder to sell Registrable Securities without registration under the Securities
Act within the limitation of the exemptions provided by (i) Rule 144 under the
Securities Act, as such Rule may be amended from time to time, or (ii) any
similar rule or

                                      -12-
<PAGE>
 
regulation hereafter adopted by the SEC.  Upon the request of any Qualified
Holder, the Company will deliver to such Qualified Holder a written statement as
to whether it has complied with such requirements.

respective representatives, administrators, heirs, successors and assigns, as
applicable, including, without limitation and without the need for an express
assignment, subsequent Qualified Holders.  If any successor, assignee or

manner, whether by operation of law or otherwise, such Registrable Securities
shall be held subject to all of the terms of this Agreement, and by taking and
holding such Registrable Securities such Person shall be entitled to receive the
benefits hereof and shall be conclusively deemed to have agreed to be bound by

                                ---------------


$6,200,000.00                                                    August 13, 1998


          FOR VALUE RECEIVED, the undersigned, ALLIN COMMUNICATIONS CORPORATION,
a Delaware corporation, its successors and assigns ("Maker"), hereby promises to
pay to the order of James S. Kelly, Jr., his heirs and assigns ("Lender"), on
the Maturity Date (as such term is defined below), if not sooner paid, the
principal sum of Six Million Two Hundred Thousand and 00/100 Dollars
($6,200,000.00) owed to Lender by the Maker pursuant to that certain Stock

additional financing thereof (up to $3,200,000) to Lender to be applied against
the accrued costs, interest and principal (in such order) then outstanding under
this Note.  In addition, in the event that Maker sells a subsidiary or
substantially all of the operating assets of a subsidiary of Maker, Maker shall
prepay to Lender, on the date that the first proceeds of such sale are received
by Maker, the proceeds of such sale (a "Subsidiary Sale") to Lender to be
applied against the accrued costs, interest and principal (in such order) then
outstanding under this Note.  If not sooner paid, all unpaid principal, accrued
interest and all other sums and costs incurred by the Lender shall be due and
payable on December 31, 1998 (the "Maturity Date") without notice, presentment
or demand.

          Principal and interest shall be made payable to Lender and forwarded

                                       3.

Maker (all of which notices are hereby waived by Maker), without incurring any
responsibility to Maker, and without the endorsement or execution by Maker of
any additional consent or waiver:

               (a) settle, compound, collect, liquidate, purchase, postpone,
     compromise, accept partial payment on, or release any Collateral (as

     may have a right of recourse, regardless of whether rights are specifically
     reserved against any person or entity not released or discharged; and

               (c) generally act and deal with Maker and the Collateral in any
     manner that Lender may see fit, without notice to any of the undersigned.

Note (the "Loan") shall have become due (at maturity, by acceleration or
otherwise) and before and after judgment, or upon the occurrence of one or more
of the Events of Default, as compensation to the Lender for the increased cost
of administering the Loan, the Loan will bear interest for each day until paid
(before and after judgment) at a rate which will be equal to 10% per annum.

          Interest on the unpaid principal amount hereof shall be computed on
the basis of a 360 day year and the actual number of days elapsed in the period
during which it accrues.

          In the event the rates of interest provided for herein or any of them
are finally determined by any governmental authority to exceed the maximum rate
of interest permitted by applicable usury or similar laws, their or its
application will be suspended and there will be charged instead the maximum rate
of interest permitted by such laws.

          Interest on the Loan shall accrue until maturity.  After maturity of
any part of the Loan (at maturity, by acceleration or otherwise), interest on
such part of the Loan will be due and payable on demand.

against the undersigned, the Maker further agrees to pay the holder hereof, in

              Allin Communications Acquires KCS Computer Services

 Allin Takes First Step Under Expansion Strategy to Acquire Regionally Dominant
                          Microsoft Solution Partners
                                        
Thursday, August 13, 1998
For Release at 4:30 pm EDT

     Pittsburgh, PA: Allin Communications Corporation (NASDAQ: ALLN) announced
today that it has acquired KCS Computer Services, Inc. ("KCS"), a Microsoft
Solutions Provider Partner headquartered in Pittsburgh with offices in
Cleveland, Ohio and Erie, Pennsylvania. A privately held firm, KCS provides
technology services nationwide through 123 information technology professionals.
The acquisition represents an important step in Allin's previously announced
strategy to expand the geographic scope of the company's consulting services
business through acquisitions.  Allin's acquisition strategy will continue to
focus on Microsoft Solution Provider Partners, or quality Microsoft Solution
Providers who can quickly be upgraded to Partner status.

     Under the terms of the acquisition, valued at approximately $16 million,
Allin has acquired all of the outstanding stock of KCS. The acquisition combines
KCS with Allin's Kent Consulting Group, a Microsoft Solutions Partner based in
the San Francisco Bay Area. Both organizations will operate under the Allin
Consulting Services banner. Microsoft Solutions Provider Partners are an elite
group of organizations who provide support for Microsoft products and who have
met Microsoft's stringent requirements relating to training and marketing.
Microsoft and its Partners also jointly develop formal yearly business plans to
address their clients' needs.  Additionally, Microsoft and its Partners conduct
joint marketing calls, strategy sessions and quarterly reviews of these business
plans.

     KCS's chief operating officer, Ron Pearce, who is responsible for day-to-
day operations, will remain with KCS in the same capacity and will report to Les
Kent, Allin's president. Jim Kelly, KCS's president, will join Allin's board of
directors but, consistent with KCS's present structure, will not be involved in
the day-to-day operations of the company.

     "KCS is a well run company with depth in the management ranks, a
concentration in Microsoft solutions, and a presence in one of the primary
markets we have targeted to expand our consulting services business," said Rich
Talarico, chairman and CEO of Allin. "Ron Pearce brings to Allin a strong
background in sales, recruiting and management in the IT services industry and
will strengthen our management team as we pursue our growth strategy. Les Kent
will be responsible for integrating the organizations and ensuring that Allin
Consulting's best practices are instituted across the organization as we meld
KCS and any other additional organizations into the Allin family."
<PAGE>
 
     Les Kent commented, "The addition of KCS to Allin Consulting is a first
step in fulfilling our vision of a network of regionally dominant Microsoft
Solution Partners. We believe that it will become increasingly difficult for the
smaller independents to gain access to the capital necessary to grow their
business and still meet Microsoft's rising standards for qualifying as a
Solutions Provider Partner. At the same time, we expect Microsoft's Windows NT
operating system to continue its explosive growth through the year 2000 and
beyond, which should intensify demand for the high-end consulting services that
Microsoft Solution Provider Partners can provide. A major component of our
growth strategy is to acquire well run organizations who will benefit from our
experience in the market and our access to capital."

     Jim Kelly explained, "My decision to consummate the sale with Allin was
driven by the desire that Rich, Les and I share, to create a national
information technology firm comprised of Microsoft Solution Provider Partners.
I am looking forward to participating in this acquisition strategy from the
board level and as an investor in the Company."

     The company will hold a conference call for securities analysts and
investors to discuss the acquisition on Friday, August 14, 1998 at 8:30 am EDT.
To join the call, dial 800/611-1148 and inform the operator that you are calling
