ITEM 2.  DISPOSITION OF ASSETS.

     On October 27, 1998, Alvey Systems, Inc., a Delaware corporation 
("Alvey" or the "Company"), completed the spin-off (the "Initial Spin-Off") 
of its wholly-owned subsidiary, McHugh Software International, Inc. 
("McHugh"), to Alvey's parent, Pinnacle Automation, Inc. ("Pinnacle"). 
Pinnacle, in turn, completed the spin-off of McHugh (the "Subsequent 
Spin-Off," and with the Initial Spin-Off, the "Spin-Off") to Pinnacle's 
common stockholders on the same date, by means of a pro rata distribution of 
the shares of McHugh common stock. The Distribution Agreement among Pinnacle, 
Alvey and McHugh, which sets forth the terms of the Spin-Off and certain 
obligations of the parties after the Spin-Off, is filed herewith as Exhibit 
10.3.  The Tax Sharing Agreement among those same parties, which sets forth 
the obligations of the parties with respect to taxes after the Spin-Off, is 
filed herewith as Exhibit 10.4.

     Together with its wholly-owned subsidiaries, Weseley Software 
Development Corp., Software Architects, Inc. and Gagnon & Associates, Inc., 
McHugh develops, markets, implements and supports open architecture, 
client/server planning and execution software products for warehouse and 
transportation management (the "McHugh Business").  Following the Spin-Off, 
Alvey will continue to own and operate its business as a leading provider of 
automated materials handling systems for manufacturing plants, distribution 
centers and warehouses (the "Systems Business"), and McHugh will continue to 
own and operate the McHugh Business.  By separating businesses with 
distinctive needs relative to capital investment, growth, financing, 
management and human resources, the boards and management of Pinnacle, Alvey 
and McHugh believe the Spin-Off will improve capital-raising efficiency and 
strategic focus at both the Systems and McHugh Businesses.

     Immediately after the consummation of the Spin-Off, also on October 27, 
1998, McHugh consummated the sale to affiliates of Advent International 
Corporation of a minority interest in McHugh for $49.5 million in cash (the 
"Advent Investment").  Upon consummation of the Advent Investment, Alvey 
received a cash payment from McHugh in the amount of $36,643,258, 
representing payment in full of intercompany indebtedness owing from McHugh 
to Alvey on the distribution date ($35,921,538) and a tax-free dividend of a 
portion of Alvey's tax basis in McHugh ($721,720).

     In order to consummate the Spin-Off and the Advent Investment, among 
other things, the receipt of consents from holders of a majority in aggregate 
principal amount of Alvey's $100,000,000 of 11-3/8% Senior Subordinated Notes 
Due 2003 (the "Notes") was required.  On September 30, 1998, Alvey received 
and accepted the requisite consents in order to amend the Indenture governing 
the Notes to permit the Spin-Off and to provide for certain other matters.  
On September 30, 1998, the First Supplemental Indenture was entered into 
between Alvey and The Bank of New York, as trustee (the "Trustee"), a copy of 
which is filed herewith as Exhibit 10.1.  To obtain the consent of its 
bondholders, Alvey agreed, among other things, to (i) pay a consent premium 
(the "Consent Premium") of $46.00 in cash for each $1,000 principal amount of 
Notes for which a consent was properly delivered prior to the expiration of 
the consent solicitation and (ii) immediately after the consummation of the 
Spin-Off, to commence an offer to all of its bondholders, on a pro rata 
basis, to purchase up to $30 million in aggregate principal 

                                       2


<PAGE>

amount of the Notes at a cash purchase price (the "Spin-Off Offer Purchase 
Price") equal to 113% of the principal amount thereof plus accrued and unpaid 
interest thereon, if any, to the date of purchase (the "Spin-Off Offer").  
Consents of holders of more than 99% of the Notes were delivered and accepted 
prior to the expiration of the consent solicitation.  Alvey commenced the 
Spin-Off Offer on October 27, 1998 and set November 24, 1998 as the 
expiration date, with the repurchase of Notes to be made on November 25, 
1998.  Upon receipt of the funds from McHugh in payment of intercompany 
indebtedness and Alvey's tax basis in McHugh, Alvey transmitted to the 
Trustee an amount of cash sufficient to fund both the payment of the Consent 
Premium (approximately $4.6 million) and the repurchase of Notes pursuant to 
the Spin-Off Offer (approximately $33.9 million).

     In addition, in order to consummate the Spin-Off, an amendment to 
Alvey's credit agreement was necessary to permit Alvey to spin-off McHugh, a 
formerly restricted subsidiary, and to release the lenders' security 
interests in McHugh's assets and capital stock.  On October 26, 1998, Alvey, 
certain of its subsidiaries (as guarantors) and NationsBank, N.A., as agent, 
entered into the Fourth Amendment, Consent Waiver and Release, a copy of 
which is filed herewith as Exhibit 10.2 (the "Bank Amendment").  Among other 
things, the Bank Amendment permits the Spin-Off and the repurchase of Notes, 
releases security interests in McHugh's assets and capital stock and amends 
certain financial covenants to reflect Alvey's corporate structure on a 
post-Spin-Off basis.  In addition, within 60 days of the Spin-Off, subject to 
compliance with certain covenants, Alvey may elect to increase availability 
under the credit facility from its current level of $30 million to $40 
million.

     Further details regarding the transactions discussed above can be found 
in the agreements and press releases filed as exhibits herewith.  In 
addition, reference is made to Alvey's pro forma financial statements filed 
herewith which present Alvey's financial information as if the Spin-Off and 
the Notes repurchase occurred on prior dates.

- -----------------
(1)  Amounts reflect the exclusion of the McHugh Business from the consolidated
     financial results, giving effect to the Spin-Off.  In addition, amounts
     give effect to the other Spin-Off-related adjustments detailed below.  The
     following Spin-Off-related expenses have not been reflected in the
     accompanying pro forma unaudited consolidated statement of operations as
     they represent nonrecurring items:  (i) $4.6 million of Consent Premium;
     (ii) $3.9 million of 

                                       6

<PAGE>

     repurchase fee on repurchased Notes; (iii) $4.5 million of estimated 
     transaction costs related to the Spin-Off, the solicitation of 
     bondholder consents (the "Solicitation"), amending and repurchasing a 
     portion of the Notes and amending Alvey's revolving credit facility; and 
     (iv) the effect of the write-off of unamortized debt issuance costs 
     relating to the Notes and Alvey's revolving credit facility. Items (i), 
     (ii), (iv) and $1.3 million of (iii) will be reflected as an 
     extraordinary charge, net of taxes, in the fourth quarter of 1998. 
     Additionally, the effects of elimination of Alvey's investment in McHugh 
     at the time of the Spin-Off and balance sheet items that do not impact 
     the statements of operations have been excluded.  Amounts for the year 
     ended December 31, 1997 also exclude the impacts of (x) nonrecurring 
     restructuring charges of $11.3 million recorded in the second quarter of 
     1997 to discontinue offering certain proprietary systems software 
     products at a Systems Business subsidiary and to recognize and 
     streamline the size of the organizational structure (collectively, the 
     "2Q 1997 Restructuring Expense") and (y) legal, accounting and other 
     nonrecurring charges of $470,000 related to a discontinued initial 
     public offering of McHugh's common stock and other strategic initiatives 
     as the Company decided in the fourth quarter of 1997 not to proceed with 
     the initial public offering and such initiatives (the "Discontinued 
     McHugh IPO").  Because of the nonrecurring nature of such charges, they 
     have been eliminated from the pro forma statements of continuing 
     operations.

(2)  Pro forma adjustments reflected in this amount include (i) a $3.4 million
     reduction in interest expense due to the repurchase of $30.0 million
     principal amount of the Notes, (ii) a $2.2 million increase to interest
     expense because, upon consummation of the Spin-Off, interest on long-term
     debt will no longer be allocated in part to McHugh and (iii) a $563,000
     increase in interest expense due to expected higher borrowing levels under
     Alvey's revolving credit facility as a result of the Spin-Off.

(3)  Pro forma adjustments reflected in this amount include (i) a $1.7 million
     reduction in interest expense due to the repurchase of $30.0 million
     principal amount of the Notes, (ii) a $1.4 million increase in interest
     expense because, upon consummation of the Spin-Off, interest on long-term
     debt will no longer be allocated in part to McHugh and (iii) a $286,000
     increase in interest expense to reflect expected higher borrowing levels
     under Alvey's revolving credit facility as a result of the Spin-Off.

(4)  Pro forma adjustments reflected in this amount include a decrease of
     approximately $480,000 for the twelve months ended December 31, 1997 and
     $240,000 for the six months ended June 30, 1998 in the amortization of debt
     issuance costs resulting from amending and repurchasing a portion of the
     Notes and amending Alvey's revolving credit facility.

(5)  Pro forma totals include adjustments to reflect the estimated income tax
     effect of the Spin-Off-related pro forma adjustments described in footnotes
     (2) through (4).

(6)  Performance measures such as EBITDA (discussed further in note (7) below)
     should not be construed as alternatives to operating income or net income
     calculated in accordance with generally accepted accounting principles
     ("GAAP") or as indicators of operating performance or liquidity.  However,
     the Company believes such non-GAAP performance measures are commonly used
     to evaluate a company's ability to service debt.

(7)  EBITDA consists of earnings before interest, income taxes and depreciation
     and amortization expense.  In 1997, EBITDA excluded the 2Q 1997
     Restructuring Expense and costs related to the Discontinued McHugh IPO.

(8)  For purposes of this computation, interest expense consists of interest on
     indebtedness, net of interest income, and does not include amortization of
     deferred financing fees charged to interest expense for such period.

(9)  This ratio is intended to compare amounts on a full-year basis; as such,
     the ratio is not presented for the six months ended June 30, 1998.

(10) Net long-term debt represents long-term debt less cash and cash
     equivalents.

     subsequent issuance or transfer of Equity Interests that results in
     any such Indebtedness being held by a Person other than a Wholly Owned
     Subsidiary of the Company and (ii) any sale or other transfer of any
     such Indebtedness to a Person that is not either the Company or a

     SECTION 120.  SECTION 11.02 OF THE INDENTURE IS AMENDED BY DELETING SUCH
SECTION THEREFROM IN ITS ENTIRETY AND REPLACING SUCH SECTION WITH THE FOLLOWING:

               SECTION 11.02.  NOTICES.  Any notice or communication shall
     be in writing and delivered in person or mailed by first class mail,
     postage prepaid, addressed as follows:  if to the Company:  9301 Olive
     Boulevard, St. Louis, Missouri  63132, Attention:  Chief Financial

     affect its sufficiency with respect to other Holders.  If a notice or
     communication is mailed to the Company, the Trustee or a Holder in the
     manner provided above, it is duly given, whether or not the addressee
     receives it.  In case by reason of the suspension of regular mail
     service or by reason or any other cause it shall be impracticable to
     give notice by mail to Holders, then such notification as shall be
     made with the approval of the Trustee shall constitute a sufficient
     notification for every purpose hereunder.

     to an amount less than the aggregate principal amount of outstanding
     Revolving Loans PLUS LOC Obligations outstanding.  

          (b)  MANDATORY REDUCTIONS.  Upon the occurrence of an Asset
     Disposition Prepayment Event, the Revolving Committed Amount automatically

<PAGE>

     not applied (or caused to be applied) by the Borrower and its Subsidiaries
     during the related Application Period to acquire Eligible Assets as
     contemplated by the terms of Section 8.4(b)

          (c)  TERMINATION DATE.  The Commitments of the Lenders and the Issuing
     Lender shall automatically terminate on the Termination Date.  The Agent
     shall promptly notify each of the Lenders of receipt by the Agent of any
     notice from the Borrower pursuant to this Section 3.4.

     period following the consummation of the Spin-Off, the Borrower shall have
     the right upon written notice to the Agent to increase the Revolving
     Committed Amount by up to $10,000,000, SUBJECT, HOWEVER, in any such case,
     to satisfaction of the following conditions precedent:
          
          (A)  no Default or Event of Default has occurred and is continuing on
     the date on which such Revolving Committed Amount increase is to become
     effective;
          
          (B)  the representations and warranties set forth in Section 6 of this
     Credit Agreement shall be true and correct in all material respects on and
     as of the date on which such Revolving Committed Amount increase is to
     become effective;
          
          (C)  on or before the date on which such Revolving Committed Amount
     increase is to become effective, the Agent shall have received, for its own
     account, the mutually acceptable fees and expenses required by separate
     agreement of the Borrower and the Agent to be paid in connection with such
     increase;
          
          (D)  such Revolving Committed Amount increase shall be an integral
     multiple of $500,000 and shall in no event be less than $2,500,000; and
          
          (E)  such requested Commitment increase shall be effective on such
     date only to the extent that, on or before such date, (A) the Agent shall
     have received and accepted a corresponding amount of Additional
     Commitment(s) pursuant to a commitment letter(s) acceptable to the Agent
     from one or more Lenders acceptable to the Agent and, with respect to any
     Lender that is not at such time a Lender hereunder, the Borrower and (B)
     each such Lender has executed an agreement in the form of SCHEDULE 3.4(D)
     hereto (each such agreement a "NEW COMMITMENT AGREEMENT"), accepted in
     writing therein by the Agent and, with respect to any Lender that is not at
     such time a Lender hereunder, the Borrower, with respect to the Additional
     Commitment of such Lender.

     7.   A new Section 6.17 is added to the Credit Agreement to read as
follows:


     6.17 YEAR 2000 COMPLIANCE.

customers with respect to the "year 2000 problem"

                                       7

<PAGE>

(that is, the risk that computer applications may not be able to properly
perform date-sensitive functions after December 31, 1999) and, based on that
review and inquiry, the Credit Parties believe that the year 2000 problem will
not result in a material adverse change in its business condition (financial
or otherwise), operations, business, assets, liabilities or prospects of the
Credit Parties taken as a whole, or on the ability of any Credit Party to
perform any material obligation under the Credit Documents to which it is
a party.

Class C Common Stock, and that Alvey subsequently distribute to Pinnacle      
such shares of McHugh Class B Common Stock and McHugh Class C Common      
Stock, whereafter Pinnacle will exchange substantially all of such

when held by the transferor; or (vi) that would be exempt from the registration
requirements of Section 5 of the Securities Act by virtue of the exemption
provided by Section 4(2) of the Securities Act if the transferor were the issuer
of the shares of McHugh Common Stock, provided that the transferee is an
"accredited investor" within the meaning of Rule 501(a) under the Securities Act
and the shares of McHugh Common Stock in the hands of such transferee remain
subject to the same restrictions on transfer as such shares were subject when
held by the transferor, or a transfer pursuant to an effective registration

equal to McHugh's then current fully absorbed rate per hour for applicable 
engineers multiplied by 200%.

that it will continue to provide software support to National Beef Packing
Company, L.P. ("NBP") in connection with the Systems and Maintenance Support

support services to NBP in connection with the NBP Agreement during the one-year
period beginning November 1, 2000 and ending October 31, 2001, Alvey shall pay
McHugh, on a time and material basis, at the rate of $150 per hour, not to
exceed $75,000 in the aggregate for such one-year period, upon the rendering of
workman-like services by McHugh and presentment by McHugh of sufficiently
detailed invoices for such services indicating the number of engineer hours
rendered.

<PAGE>

involving Mitchell J. Weseley and those certain guarantees by Alvey (and 
Pinnacle, as noted) of the obligations of each of McHugh and its wholly owned 
subsidiary, Weseley Software Development Corp. ("Weseley"), under leases of 
real property occupied by McHugh and/or Weseley at the date of this Agreement 
at: 20700 Swenson Drive, Suite 400, Waukesha, WI 53186 (guaranteed by McHugh 
and Pinnacle); 1000 Bridgeport Avenue, Shelton, CT 06484; and 5520 Dillard 
Drive, Suite 200, Cary, NC 27511, and under Master Lease No. 155056 of 
computer equipment from Computer Sales International, Inc., dated as of July 
13, 1998 and (ii) any and all lawsuits, actions or proceedings to enforce 
this indemnity.

     3.3    NOTIFICATION OF CLAIMS.  For the purpose of this Article III, the
term "Indemnifying Party" shall mean the party having an obligation hereunder to
indemnify the other party pursuant to this Article III, and the term
"Indemnified Party" shall mean the party having the right to be indemnified
pursuant to this Article III.  Whenever any claim shall arise for
indemnification under this Article III, including any claim related to a
Distribution Action, the Indemnified Party shall promptly notify the
Indemnifying Party in writing of such claim and, when known, the facts
constituting the basis for such claim (in reasonable detail).  Failure by the
Indemnified Party to so notify the Indemnifying Party shall not relieve the
Indemnifying Party of any liability hereunder except to the extent that such
failure materially prejudices the Indemnifying Party.

     3.4    INDEMNIFICATION PROCEDURES.

     (a)    For all claims other than Distribution Actions:

            (i)     After the notice required by Section 3.3 is received by the
Indemnifying Party, if the Indemnifying Party undertakes to defend any such
claim, then the Indemnifying Party shall be entitled, if it so elects, to take
control of the defense and investigation with respect to such claim and to
employ and engage attorneys of its own choice to handle and defend the same, at
the Indemnifying Party's cost, risk and expense, upon written notice to the
Indemnified Party of such election, which notice acknowledges the Indemnifying
Party's obligation to provide indemnification hereunder.  The Indemnifying Party
shall not settle any third-party claim that is the subject of indemnification
without the written consent of the Indemnified Party, which consent shall not be
unreasonably withheld; provided, however, that the Indemnifying Party may settle
a claim without the Indemnified Party's consent if such settlement (x) makes no
admission or acknowledgment of liability or culpability with respect to the
Indemnified Party, (y) includes a complete release of the Indemnified Party and
(z) does not require the Indemnified Party to make any payment or forego or take
any action.  The Indemnified Party may, at its own cost, participate in any
investigation, trial and defense of such lawsuit, action or proceeding
controlled by the Indemnifying Party and any appeal arising therefrom.  If there
are one or more legal defenses available to the Indemnified Party that conflict
with those available to the Indemnifying Party, the Indemnified Party shall have
the right, at the expense of the Indemnifying Party, to assume the defense of
the lawsuit, action or proceeding; PROVIDED, HOWEVER, that the Indemnified Party
may not settle such lawsuit, action or proceeding without the consent of the
Indemnifying Party, which consent shall not be unreasonably withheld.

            (ii)    If, after receipt of a claim notice pursuant to Section 3.3,
the Indemnifying Party does not undertake to defend any such claim, the
Indemnified Party may, at the Indemnifying 

                                       9

<PAGE>

Party's expense, but shall have no obligation to, contest any lawsuit, action 
or proceeding with respect to such claim and the Indemnifying Party shall be 
bound by the result obtained with respect thereto by the Indemnified Party 
(including, without limitation, the settlement thereof without the consent of 
the Indemnifying Party). 

            (iii)   At any time after the commencement of defense of any
lawsuit, action or proceeding, the Indemnifying Party may request the
Indemnified Party to agree in writing to the abandonment of such contest or to
the payment or compromise by the Indemnifying Party of such claim, whereupon
such action shall be taken unless the Indemnified Party determines that the
contest should be continued and so notifies the Indemnifying Party in writing
within 15 days of such request from the Indemnifying Party.  If the Indemnified
Party determines that the contest should be continued, the Indemnifying Party
shall be liable hereunder only to the extent of the lesser of (y) the amount
which the other party(ies) to the contested claim had agreed to accept in
payment or compromise as of the time the Indemnifying Party made its request
therefor to the Indemnified Party or (z) such amount for which the Indemnifying
Party may be liable with respect to such claim by reason of the provisions
hereof.

     (b)    Pinnacle and Alvey shall have responsibility to defend against any
Distribution Actions, PROVIDED, HOWEVER, that (i) if Pinnacle and Alvey shall
elect not to assume the defense of such Actions or (ii) if McHugh reasonably
determines that there may be a conflict between the positions of Pinnacle and
Alvey, on the one hand, and of McHugh, on the other hand, in defending such
claim or action, then separate counsel shall be entitled to participate in and
conduct the defense, and Pinnacle and Alvey shall be liable for any legal or
other expenses reasonably incurred by McHugh in connection with the defense. 
Pinnacle and Alvey shall not be liable for any settlement of any action, suit,
claim or proceeding effected without its written consent; PROVIDED, HOWEVER,
that Pinnacle shall not unreasonably withhold, delay or condition its consent.
Pinnacle and Alvey further agree that they will not, without McHugh's prior
written consent, settle or compromise any claim or consent to entry of any
judgment in respect thereof in any pending or threatened action, suit, claim or
proceeding in respect of which indemnification may be sought hereunder (whether
or not McHugh is an actual or potential party to such action, suit, claim or
proceeding) unless such settlement or compromise includes an unconditional
release of McHugh from all liability arising out of such action, suit, claim or
proceeding..

     (c)    With respect to all claims, including any Distribution Actions, the
Indemnified Party shall cooperate in all reasonable respects with the
Indemnifying Party and its attorneys in the investigation, trial and defense of
any lawsuit, action or proceeding with respect to such claim and any appeal
arising therefrom (including the filing in the Indemnified Party's name of
appropriate cross claims and counterclaims).

     3.5    INDEMNIFICATION OF INSURED LOSS.  

     (a)    The amount of any Loss for which indemnification is provided under
this Article III shall be net of any amounts recovered or recoverable by the
Indemnified Party under insurance policies covering such Loss.  It is the
express intention of the parties hereto that no transaction contemplated by this
Agreement eliminate or reduce insurance coverage available to any party hereto
with respect to a Loss.

     (b)    If the Indemnified Party  makes any payment under this Article III
in respect of any Loss, the Indemnifying Party shall be subrogated, to the
extent of such payment, to the rights of the Indemnified Party against any
insurer or third party with respect to such Loss.  The Indemnified Party shall
execute any required documents or instruments, serve as a named plaintiff or
take any other similar steps necessary to effectuate such subrogation.

     3.6    SURVIVAL OF INDEMNIFICATION.  The obligations to indemnify and hold
harmless a party hereto shall survive with respect to any claim until any
applicable statute of limitations with respect to such claim expires; PROVIDED
that prior to the expiration of the applicable statute of limitations period the
Indemnified Party shall have delivered a claim notice in accordance with
Section 3.3 hereof to the Indemnifying Person.

                                    ARBITRATION

     4.1    IN GENERAL.  Any controversy, dispute or disagreement between the
parties hereto arising out of or relating to this Agreement, which controversy,
dispute or disagreement is not settled in writing within 30 days after the date
on which a party subject to this Agreement gives written notice to the other
party(ies) that a controversy, dispute or disagreement exists, shall be
submitted to binding arbitration pursuant to this Article IV, which shall
constitute the exclusive remedy for the settlement of any controversy, dispute
or disagreement between the parties concerning this Agreement, including whether
such controversy, dispute or disagreement is subject to arbitration pursuant to
this Article IV.

     4.2    SELECTION OF ARBITRATORS.  Within 45 days after the date on which a
party hereto gives written notice to the other party(ies) that a controversy,
dispute or disagreement exists arising out of or relating to this Agreement, the
parties agree to each select one arbitrator to hear and decide such matters. 
The two arbitrators so chosen shall then select a third arbitrator.  Each of the
arbitrators chosen shall be impartial and independent of all parties to this
Agreement and shall be a retired judge or lawyer experienced in corporate law
matters.  If either of the parties fails to select an arbitrator within 20 days
after the end of such 45-day period, or if the arbitrators chosen fail to select
a third arbitrator within such 20 days, then any party may in writing request
the judge of the United States District Court for the Southern District of New
York senior in term of service to appoint the arbitrator or arbitrators.

     4.3    CONDUCT OF PROCEEDINGS.  Each arbitration hearing shall be held at
a place in New York City, New York acceptable to a majority of the arbitrators. 
The arbitration shall be conducted 

                                       11

<PAGE>

in accordance with the Commercial Arbitration Rules of the American 
Arbitration Association to the extent such rules do not conflict with the 
terms of this Section.  The decision of a majority of the arbitrators shall 
be reduced to writing and shall be binding on the parties. Judgment upon the 
award(s) rendered by a majority of the arbitrators may be entered and 
execution had in any court of competent jurisdiction or application may be 
made to such court for a judicial acceptance of the award and an order of 
enforcement.  The charges and expenses of the arbitrators and all costs of 
arbitration shall be paid by the non-prevailing party as determined by a 
majority of the arbitrators.  The arbitration shall commence within 10 days 
after the arbitrators are selected.  In fulfilling their duties with respect 
to determining the amount of any loss or claim, the arbitrators may consider 
such matters as, in the opinion of the arbitrators, are necessary or helpful 
to make a proper determination.  The arbitrators may consult with and engage 
disinterested third parties to advise the arbitrators.  If any of the 
arbitrators selected hereunder should die, resign or be unable to perform his 
or her duties hereunder, the remaining arbitrators or such senior judge (or 
such judge's successor) shall select a replacement arbitrator.  The procedure 
set forth herein for selecting the arbitrators shall be followed from time to 
time as necessary.

Party") with written notice of any claim or of the commencement of any 
proceeding against the Indemnified Party that may result in any 
indemnification hereunder, and shall provide the Indemnifying Party with 
notice of and an opportunity to attend any meeting with taxing authorities 
regarding the claim or proceeding.  The Indemnified Party shall not (unless 
otherwise required by a proper notice of assessment of levy) pay, settle, 
compromise or concede any portion of the claim or issue relating thereto

Indemnifying Party's sole cost (including any reasonable out-of-pocket costs

Neither the Pinnacle Companies nor the McHugh Companies shall, without the

compromise any Tax claim or dispute with a Taxing authority if the effect of
such settlement or compromise would be a material increase in the Tax Liability
of the other group.

FOR IMMEDIATE RELEASE
                                          
                   PINNACLE AUTOMATION AND ALVEY SYSTEMS ANNOUNCE
                           COMPLETION OF McHUGH SPIN-OFF

     ST. LOUIS, OCTOBER 30, 1998   Pinnacle Automation, Inc., parent company of
Alvey Systems, Inc. and a leading provider of materials flow and information
flow technology, announced the spin-off of Alvey's wholly-owned subsidiary
McHugh Software International, Inc. The companies announced that private equity
firm Advent International, along with GE Capital, purchased a significant
minority equity position in McHugh, establishing McHugh as an independent
company with its own board of directors, shareholders and capital structure.

     McHugh is the industry's leading provider of logistics execution systems
for transportation, warehousing and labor management.

     "The completion of the spin-off creates two separate, but stronger,
independent companies," said Stephen J. O'Neill, Pinnacle president and chief
executive officer. "This separation will provide the management and capital
structure necessary for McHugh to realize its full potential, and allow Pinnacle
to focus its resources and efforts on its systems business."

     Pinnacle will continue to deliver integrated materials and information flow
systems, and has agreed with McHugh to implement McHugh's software into
Pinnacle's comprehensive supply chain management solutions.

     As a result of this transaction, Pinnacle emerges as a financially stronger
company:  long-term debt decreased by $30 million; $18.6 million of preferred
stock was redeemed; and annual interest expense decreased by approximately $3
million. Pinnacle's improved capital structure provides the basis to support the
company's continued growth.

     Pinnacle Automation, Inc. is a leading provider of materials flow and
information flow capabilities, providing customers with solutions to meet all
their supply chain needs. The five companies comprising Pinnacle produce
equipment and related software and controls that enable manufacturers,
distributors and retailers to operate their manufacturing plants, distribution
centers and warehouses more efficiently.
