Item 2.  Acquisition or Disposition of Assets

Acquisition of Norment Industries, Inc. Capital Stock.

     Pursuant to the terms of a certain Stock Purchase Agreement entered
into by and between CompuDyne Corporation ("the Company") and Apogee
Enterprises, Inc. (the "Seller"), dated as of November 10, 1998, and
amended as of November 28, 1998 the Company on December 3, 1998, 
consummated the acquisition, as of November 28, 1998, of all of the
capital stock of Norment Industries, Inc. ("Norment") and Norshield
Corporation ("Norshield") from the Seller.
 
     Norment and Norshield represent the two subsidiaries comprising
Apogee's Detention & Security business unit. Seller's Detention &
Security business unit is based in Montgomery, Alabama, and is a leader
in providing security products and related systems integration services
for prisons, courthouses and embassies.

     Norment is the leading systems integrator and manufacturer of
physical and electronic security systems for the corrections market and
consists of four divisions.  SESCO is the largest detention system
contractor in the United States.  Trentech is one of the leading
electronic security systems manufacturer and integrator serving the
corrections industry.  Airteq manufactures the most technologically
advanced lock product line in the corrections industry.  Engineered
Maximum Security Systems ("EMSS") is a leading detention system
contractor located on the West Coast.  Norshield is the world's largest
manufacturer and supplier of ballistic, attack and blast resistant
products.  

     The consideration  paid to the Seller for the stock of Norment and
Norshield was $22.5 million in immediately available funds, subject to
adjustment upon the completion of an audited closing date balance sheet. 

 
     The Company reviewed the recent financial performance of Norment
and Norshield, visited facilities, evaluated management, and considered
current backlog and future business potential in coming to the
determination of the consideration to be paid.  The Company also
considered the ability of Norment and Norshield business to complement
CompuDyne's other security-related business lines consistent with
CompuDyne's strategic direction.

     In order to provide the funds required to purchase the stock of
Norment and Norshield and provide working capital, the Company issued $9
million  in subordinated notes with warrants for 297,924 shares of
CompuDyne common stock and 1,075,507 shares of the corporation's common
stock for a purchase price of $3 million to William Blair Mazzanine

Working Capital (as defined below) estimated as of the opening of
business on the Closing Date (the "Estimated Net Working Capital").  The
Estimated Net Working Capital shall be calculated in accordance with

provided to Purchaser pursuant to Section 2.04 hereof (the "Working
Capital Balance Sheet"); provided that there shall be no reserve or
accrual for warranty claims related to any projects which are not
Transferred Projects or Customer Orders.  As used herein, the term "Net
Working Capital" shall mean an amount equal to the excess of total
current assets over total current liabilities of the Business calculated
in accordance with GAAP on a consistent basis with the Working Capital
Balance Sheet.
 
(b)  If the Estimated Net Working Capital is less than $16,352,196
("Minimum Target Net Working Capital"), then the Purchase Price payable
to Seller at Closing shall be reduced by an amount equal to the amount of
such deficit (the "Estimated Working Capital Deficit Adjustment").  If
the Estimated Net Working Capital is in excess of $19,180,349 (the
"Maximum Net Working Capital" Purchaser shall pay to Seller an amount
equal to the amount of such excess (the "Estimated Working Capital
Surplus Adjustment"). 
 
(c)  Within forty-five (45) days after the Closing Date, the Purchaser
will prepare and deliver to the Seller (i) a draft consolidated balance
sheet (the "Draft Closing Date Balance Sheet") for the Business as of the
Closing Date, including related schedules and work papers, (ii) a
computation and determination of the Net Working Capital as of the
Closing Date, and (iii) a computation and determination of the Adjusted
Purchase Price.
 
(d)  If Seller has any objections to the Draft Closing Date Balance
Sheet, it will deliver a detailed statement describing such objections to
the Purchaser within fifteen (15) days of receipt thereof.  Purchaser and
Seller will use reasonable efforts to resolve any such objections among
themselves.   If the parties do not obtain a final resolution within
thirty (30) days after Purchaser has received the statement of
objections, Purchaser and Seller will select an independent accounting
firm mutually acceptable to them to resolve any remaining objections. If  
Purchaser and Seller are unable to agree on the choice of an accounting
firm, they will select by lot a nationally-recognized accounting firm
which is not then currently and has not provided the principal outside
auditing services to any of the parties hereto or any of their Affiliates
within the past three (3) years, which shall be jointly instructed by the
Purchaser, on the one hand, and the Seller, on the other hand, to
determine the Net Working Capital and the Adjusted Purchase Price in
accordance with this Agreement. (The accounting firm selected by either
mutual agreement or lot is herein referred to as the "Accountant".)  The
Accountant shall deliver to each of Purchaser and Seller its
determinations within thirty (30) days after receiving the joint
instructions from Purchaser and Seller, and the determinations of the
Accountant will be set forth in writing and will be conclusive and
binding upon the parties.  The expenses of the Accountant shall be borne
equally by Purchaser and Seller in amounts determined in reverse
proportion to the net benefit derived by each from any modification
resulting from the Seller's objection to the Draft Closing Balance Sheet. 
The Purchaser will give the Seller the Draft Closing Date Balance Sheet   
revised to reflect the Accountant's determinations.   The "Closing Date
Balance Sheet" shall mean the Draft Closing Date Balance Sheet, together
with any revisions thereto pursuant to this Section 1.07, including the
determination of the Accountant.  The "Adjusted Purchase Price" shall
mean the Purchase Price, together with any revisions thereto pursuant to
this Section 1.07, including the determination of the Accountant.
 
(e)  For purposes of Seller's review of the Closing Date Balance Sheet
and the Adjusted Purchase Price, Purchaser will make reasonably available
to Seller and its accountants and other representatives the work papers
and backup materials used in preparing the Draft Closing Date Balance
Sheet at reasonable times and upon reasonable notice at any time during
(i) the preparation by Purchaser of the Draft Closing Date Balance Sheet,
(ii) the review by Seller of the Draft Closing Date Balance Sheet, and
(iii) the resolution by the parties of any objections thereto.
 
(f)  If the Net Working Capital as of the Closing Date is less than the
Minimum Net Working Capital by more than the Estimated Working Capital
Deficit Adjustment, Seller shall pay to Purchaser an amount equal to the
amount of such deficit over the Estimated Working Capital Deficit
Adjustment plus, if any, the Estimated Net Working Capital Surplus
Adjustment.  If the Net Working Capital as of the Closing Date is less
than the Minimum Net Working Capital by less than the Estimated Working
Capital Deficit Adjustment, Purchaser shall pay to Seller the difference
between such actual deficit and the Estimated Working Capital Deficit
Adjustment.  If Net Working Capital as of the Closing Date exceeds
Maximum Net Working Capital by more than the Estimated Working Capital
Surplus Adjustment, Purchaser shall pay to Seller an amount equal to the
amount of such excess over the Estimated Working Capital Surplus
Adjustment plus, if any, the Estimated Working Capital Deficit
Adjustment.  If Net Working Capital as of Closing Date exceeds the Target
Net Working Capital by less than the Estimated Working Capital Surplus
Adjustment, Seller shall pay to Purchaser an amount equal to the
difference between the Estimated Working Capital Surplus Adjustment and
such actual excess amount.  All payments to be made under this Section
1.07(f) shall be made no later than five (5) Business Days after the
earliest to occur of (i) the 30th day after the Draft Closing Date
Balance Sheet shall have been given by Purchaser to Seller, if Seller
shall not have objected to the Draft Closing Date Balance Sheet within
such period; (ii) the first business day after which the Purchaser and
Seller have resolved any objection raised by Seller; or (iii) the first
business day after the date on which the determination of the Accountant
referred to in Section 1.06(d) above is given to Purchaser and Seller.
       
1.08 Section 338(h)(10) Election and Allocation. Seller and Purchaser
agree to make a joint election under Section 338(h)(10) of the
Code to treat the sale of the  Shares as a sale of the assets of the
Companies to Purchaser.  The Adjusted Purchase Price under this Agreement
shall be allocated between each of the Companies based on the net book
value of each of the Companies as of the Closing Date and then allocated
in accordance with Schedule 1.08 hereto.  After the Closing, the parties
shall make consistent use of the allocation specified in Schedule 1.08
for all Tax purposes and in any and all filings, declarations and reports
with the IRS in respect thereof, including the reports required to be
filed under Section 1060 of the Code, if applicable, it being understood
that Purchaser shall prepare and deliver IRS Forms 8594 and 8023 to
Seller within forty-five (45) days after the Closing Date for Seller's
review and approval if such forms are required to be filed with the IRS. 
In any proceeding related to the determination of any Tax, neither
Purchaser nor Seller or their respective Affiliates shall contend or
represent that such allocation is not a correct allocation.



                                ARTICLE II
                 REPRESENTATIONS AND WARRANTIES OF SELLER


     Seller, as to itself and as to each of the Companies, hereby
represents and warrants to Purchaser (and with respect to Section
2.24(b), Purchaser acknowledges and agrees) as follows as of the date
hereof:

2.01 Organization and Good Standing.  

(a)  Seller is a corporation validly existing and in good standing under
the Laws of the State of Minnesota.  Each Company is a corporation
validly existing and in good standing under the laws of its jurisdiction
of incorporation, with full corporate power and authority to conduct it
business as it is now being conducted, to own or use the properties and
assets that it purports to own or use, and to perform all its obligations
under the Contracts included in the Acquired Assets.   Each Company is
duly qualified to do business as a foreign corporation and is in good
standing under the laws of each state or other jurisdiction in which
either the ownership or use of the properties owned or used by it, or the
nature of the activities conducted by it, requires such qualification,
except as disclosed on Schedule 2.01(a) and except for those
jurisdictions in which the failure to be qualified and in good standing
would not have, and would not reasonably be expected to have a Material
Adverse Effect on the Business.
  
(b)  The Company has no subsidiaries except as disclosed on Schedule
2.01(b), and does not own any shares of capital stock or other securities
of any other Person.

2.02 Enforceability; Authority; No Conflict.

(a)  This Agreement constitutes the legal, valid, and binding obligation
of Seller, enforceable against it in accordance with its terms.  Upon the
execution and delivery by Seller of the documents to be executed and
delivered by Seller at the Closing (collectively, the "Transaction
Documents"), each of the Transaction Documents will constitute the legal,
valid, and binding obligation of Seller, enforceable against Seller in
accordance with its terms.  Seller has the corporate power and authority
to execute and deliver this Agreement and the Transaction Documents to
which it is a party and to perform its obligations under this Agreement
and the Transaction Documents to which it is a party.
  
(b)  Except as set forth in and subject to the provisions of Schedule
2.02(b), neither the execution and delivery of this Agreement nor the
consummation or performance of any of the transactions contemplated
hereby will, directly or indirectly (with or without notice or lapse of
time):

(i)  contravene, conflict with, or result in a violation or breach of (A)
any provision of the organizational documents of Seller, or (B) any
resolution adopted by the board of directors or the shareholders of
Seller;
            
(ii) contravene, conflict with, or result in a violation or breach of, or
give any governmental body or other Person the right to challenge any of
the transactions contemplated hereby or to exercise any remedy or obtain
any relief under, any Law or any Order to which Seller or either Company,
or any of the assets of either Company, may be subject except where such
contraventions, conflicts, violations, breaches, and rights (A) would
not, or would not reasonably be expected to, in the aggregate have a
Material Adverse Effect on the Business, or (B) would occur as a result
of the identity or the legal or regulatory status of Purchaser or its
Affiliates;
            
(iii) contravene, conflict with, or result in a violation or breach of
any of the terms or requirements of, or give any Governmental Authority
the right to revoke, withdraw, suspend, cancel, terminate, or modify, any
Governmental Authorization that is held by either Company or that
otherwise relates to the assets or the business of either Company except
where such contraventions, conflicts, violations, breaches, and rights
(A) would not, or would not reasonably be expected to, in the aggregate
have a Material Adverse Effect on the Business; or (B) would occur as a
result of the identity or the legal or regulatory status of Purchaser or
its Affiliates;
            
(iv) contravene, conflict with, or result in a violation or breach of any
provision of, or give any Person the right to declare a default or
exercise any remedy under, or to accelerate the maturity or performance
of, or to cancel, terminate, or modify, any Contract included in the
Acquired Assets except where such contraventions, conflicts, violations,
breaches and rights would not, or would not reasonably be expected to, in
the aggregate have a Material Adverse Effect on the Business; or
            
(v)  result in the imposition or creation of any Lien upon or with
respect to any of the Acquired Assets, except for any imposition or
creation of any Lien imposed by any action of Purchaser or at Purchaser's
direction.

(c)  Except as set forth in Schedule 2.02(c), neither of the Companies
nor Seller is required to give any notice to or obtain any consent from
any Person in connection with the execution and delivery of this
Agreement or the consummation or performance of any of the transactions
contemplated hereby except where failure to give such notice or obtain
such consent would not, or would not reasonably be expected to, in the
aggregate have a Material Adverse Effect on the Business.
  
2.03 Capitalization.  The authorized equity securities of Norment consist
of 1,000 shares of common stock, par value $.01 per share, of which 100
shares are issued and outstanding.  The authorized equity securities of
Norshield consist of 10,000 shares of common stock, par value $.01 per
share, of which 1,000 shares are issued  and outstanding.  Seller is and
will be on the Closing Date the record and beneficial owner of all of the
shares of equity securities of each Company issued and outstanding, free
and clear of all Liens except for any Liens to be released at the
Closing.  All of the outstanding equity securities of each Company have

transfer of any equity securities or other securities of either Company. 
None of the securities of either Company was issued in violation of Law. 
Except as set forth in Schedule 2.01(b), neither Company  owns, or has
any right to acquire, any securities of any Person or any direct or    
indirect equity or ownership interest in any other business.

2.04 Financial Statements.  Prior to the execution of this Agreement,
Seller has delivered to Purchaser true and complete copies of the
following financial statements:

(a)  the unaudited, consolidating balance sheets of the Business dated as
of February 28, 1996, 1997 and 1998, May 31 1998, and August 29, 1998
(the latter of which is referred to herein as the "Balance Sheet"); and
  
(b)  the unaudited consolidating statements of income for the Business
for the year ended February 28, 1996, 1997 and 1998, and for the
quarterly periods ended May 31, 1998 and August 29, 1998.

Except as set forth on Schedule 2.04, all such financial statements were
prepared in accordance with GAAP applied on a consistent basis throughout
the periods and present fairly the financial condition and results of
operations of the Business, as of the respective dates thereof and for
the respective periods covered thereby except for the absence of
footnotes and normal year-end adjustments which an audit would reveal and
which will not have a Material Adverse Effect on the Business.

2.05 Books and Records.  The books of account and other financial records
of each Company, all of which have been made available to Purchaser, are
complete and correct in all material respects.  The minute books of each
Company are complete and accurate in all material respects, and contain
records of all meetings held (and consents in lieu of meetings executed
by) the shareholders and the board of directors of each Company.

2.06 Sufficiency of Assets. Except as set forth on Schedule 2.06, the
Acquired Assets constitute all of the assets, tangible and intangible, of
any nature whatsoever, required  to operate the Business as currently
operated by the Companies, except for such assets the absence of which
would not, or would not be reasonably expected to, result in a Material
Adverse Effect on the Business.

2.07 Description of Real Property.

(a)  Owned Real Property.  Schedule 2.07(a) contains a true and correct
legal description and common address of all tracts and parcels of land
owned by each Company or owned by an Affiliate of Seller and used in the
Business which will be owned by one of the Companies as of the Closing
Date (the "Real Property").
    
(b)  Leased Real Property.  Schedule 2.07(b) contains a true and correct
common address of all tracts and parcels of land leased by each Company
or leased by an Affiliate of Seller which, subject to the consent of the
lessor, if required, to the assignment of such lease by such Affiliate to
one of the Companies, will be leased by one of the Companies as of the
Closing Date, and a true and correct description (by subject property,
name of lessor and lease term) of all related leases (the "Leases").

2.08 Leases.  Except as disclosed on Schedule 2.08, each of the Leases is
a valid and binding obligation of the respective Company, is enforceable
against the respective Company in accordance with its terms and is, to
Seller's Knowledge, in full force and effect.  There are no offsets or
defenses by either of the Companies or, to Seller's Knowledge, the other
party thereto under the Leases.  There are no existing material defaults
by either of the Companies, and no events or circumstances have occurred
which, with or without notice or lapse of time or both, would constitute
material defaults by either of the Companies, under any of the  Leases. 
Except as described in Schedule 2.08, the sale of the Shares by Seller to
Purchaser hereunder will not (i) permit the lessor to accelerate the rent
or cause the terms of any of the Leases to be renegotiated, (ii)
constitute a default under any of the Leases or (iii) require the consent
of the lessor under the Leases.

2.09 Title to Assets and Existing Evidence of Title to Real Property. 

Each Company owns or will, as of the Closing Date, own good and
marketable title to all of the Real Property, and owns or will, as of the

case free and clear of any Liens, other than:

(a)  Permitted Liens and as described on Schedule 2.09(a); and
  
(b)  Liens described in Schedule 2.09(b), all of which will be removed at
or prior to the Closing.  

Seller has delivered to Purchaser true and complete copies of all deeds,
existing title insurance policies and surveys of or pertaining to the
Real Property in Seller's or the Companies' possession.

2.10 Condition of Facilities.  Except as disclosed on Schedule 2.10:

(a)  Real Property.  Use of the Real Property for the various purposes
for which it is presently being used is permitted as of right under all
material zoning laws and is not subject to "permitted non-conforming" use
or structure classifications.  The Improvements are in compliance with
all Laws in all material respects, including zoning and building laws. 
The  Improvements are in good repair and in good condition in all
material respects, ordinary wear and tear excepted and, to Seller's
Knowledge, are free from patent and latent defects.  To Seller's
Knowledge, no part of the Improvements encroaches on any real property
not included in the Real Property and there are no Improvements primarily
situated on adjoining property which encroach on any part of the Real
Property.  To Seller's Knowledge, there is no existing or proposed plan
to modify or realign any street or highway or any existing or proposed
eminent domain proceeding that would result in the taking of any material
part of any Facility or that would materially prevent or hinder the
continued use of any Facility as heretofore used in the conduct of the
Business.
  
(b)  Tangible Personal Property.  The Tangible Personal Property is in
good repair and good operating condition in all material respects,
ordinary wear and tear excepted, and, to Seller's Knowledge, is free from
material latent and patent defects.  All material Tangible Personal
Property is under the possession or control of the Companies and their
employees.

2.11 Accounts Receivable.  All accounts receivable that are reflected on
the Balance Sheet or on the accounting records of the Company as of the
Closing Date represent or will represent valid obligations arising from
sales actually made, to be made, or services actually performed or to be
performed by the Company in the Ordinary Course of Business except for
billing errors in the Ordinary Course of Business that will not have a
Material Adverse Effect on the Business.  No Inter- Company Receivables
are reflected on the Balance Sheet or any of the other financial
statements described in Section 2.04 above.  Schedule 2.11 contains a
complete and accurate list of all accounts receivable as of the date of
the Balance  Sheet, which list sets forth the aging of each such account
receivable.  Since the date of the Balance Sheet, the Company has not
changed its normal credit and collection  practices.

2.12 Inventories.  Inventories now on hand that were purchased subsequent
to the date of the Balance Sheet were purchased in the Ordinary Course of
Business of the  Company at a cost, to Seller's Knowledge, consistent
with market prices prevailing at the time of purchase.  


2.13 Taxes.  Subject to the disclosures on Schedule 2.13:

(a)  Each Company, Seller or one of Seller's Affiliates has duly filed or
caused to be filed (or obtained valid, currently effective extensions for
filing set forth on Schedule 2.13) all federal, state, local and foreign
income, franchise, excise, payroll, sales and use, property, provider,
withholding and other tax returns, reports, estimates and information and
other statements or returns which relate to the Business (including all
federal income tax returns for the consolidated group of which the
Companies are a part) and which are required to be filed by or on behalf
of it pursuant to Law ("Tax Returns").  All such Tax Returns were correct
in all material respects as filed and reflect in all material respects
the federal, state, local and foreign income, franchise, excise, payroll,
sales and use, property, provider, withholding and other taxes, duties,
fees, imposts and governmental charges (and charges in lieu of any
thereof), together with interest, and additions to tax and penalties
required to be paid or collected by (or allocable to) either Company
(collectively "Taxes").  Seller, one of Seller's Affiliates, or one of
the Companies (i) has paid or caused to be paid all Taxes as shown due on
the Tax Returns and on any assessment received by it with respect to the
Business, and (ii) has properly and fully recorded as accrued or deferred
liabilities all Taxes for any period from the date of the last reporting
period covered by such Tax Returns; provided, however, that any such
accrued or deferred liability shall be a Seller Liability in accordance
with Section 1.04(a).  Neither Company nor Seller has received any
written notice of any audit, or any dispute or claim being threatened by
any relevant taxing authority concerning any such Tax Return or liability
for such Taxes.
  
(b)  There is no Tax sharing or allocation agreement that will require
any payment by either Company after the Closing Date except as provided
in Section 1.02(f) with respect to refunds of Taxes.  Neither Company is
nor within the five years immediately preceding the Closing Date has been
an "S" corporation under the Code.

2.14 Employee Benefits.  Seller and Purchaser acknowledge and agree that,
except for any multi-employer pension plan to which contributions are
made for union employees in the Business pursuant to a collective
bargaining agreement, all of the Employee Plans are Seller's plans and
will be retained by Seller after Closing so that after Closing such
Employee Plans shall not be applicable to the Transferred Employees and
Purchaser will need to implement its own employee benefit plans.

(a)  Set forth on Schedule 2.14(a) is a complete and correct list of all
"employee benefit plans" as defined by Section 3(3) of ERISA, all
specified fringe benefit plans as defined in Section 6039D of the Code,
and all other bonus, incentive compensation, deferred compensation,
profit sharing, stock option, stock appreciation right, stock bonus,
stock purchase, employee stock ownership, savings, severance,
supplemental unemployment, layoff, salary continuation, retirement,
pension, health, life insurance, disability, accident, group insurance,
vacation, holiday, sick leave, fringe benefit or welfare plan, and any
other employee compensation or benefit plan, agreement, policy, practice,
commitment, contract, or understanding (whether qualified or
nonqualified, currently effective or terminated, written or unwritten),
and any trust, escrow or other agreement related thereto, that (i) is
maintained or contributed to by either Company or any other corporation
or trade or business controlled by, controlling, or under common control
with either Company (within the meaning of Section 414 of the Code or
Section 4001(a)(14) or 4001(b) of ERISA) ("ERISA Affiliate") and relating
to employees of the Business, and (ii) provides benefits, or describes
policies or procedures applicable to any current employee of either
Company or the dependents of any thereof, regardless of whether funded
(the "Employee Plans"). 
  
(b) Seller has made available to Purchaser true, accurate and complete
copies of (i) the documents comprising each Employee Plan(or, with
respect to any Employee Plan which is unwritten, a detailed written
description of eligibility, participation, benefits, funding
arrangements, assets and any other matters which relate to the
obligations of the Company or any ERISA Affiliate), (ii) all collective
bargaining agreements pursuant to which contributions are currently made
or obligations incurred (including both pension and welfare benefits) by
either Company or with respect to the employees of the Business, and
(iii) all current summary plan descriptions and employee handbooks
regarding the Employee Plans.
  
(c)  Full payment has been made of all amounts which are required under
the terms of each Employee Plan to be paid as contributions by the
Companies, Seller or Seller's Affiliates with respect to the last day of
the most recent fiscal year of such Employee Plan ended on or before the
date of this Agreement.  No accumulated funding deficiency (as defined in
Section 302 of ERISA and Section 412 of the Code) has been incurred with
respect to such Employee Plan, whether or not waived provided that no
representations are made as to the accumulated deficiency status of any
multi-employer plan as defined in Section 3(37) of ERISA (the
"Multi-Employer Plan").  Neither Company is required to provide security
to an Employee Plan under Section 401(a)(29) of the Code.  Each Company,
Seller or an Affiliate of Seller has paid in full all required insurance
premiums, subject only to normal retrospective adjustments in the
ordinary course, with regard to the Employee Plans for policy years or
other applicable policy periods ending on or before the Closing Date.  To
the extent any such retrospective adjustment results in a refund with
respect to any period ending on or prior to the Closing, such refund
shall be an Excluded Asset and to the extent such adjustment shall result
in an obligation with respect to any period ending on or prior to the
Closing, such obligation shall be a Seller Liability.
  
(d)  Except as disclosed in Schedule 2.14(d), no Employee Plan, if
subject to Title IV of ERISA, has been completely or partially
terminated.  The Pension Benefit Guaranty Corporation ("PBGC") has not
instituted or, to Seller's Knowledge, threatened a proceeding to
terminate any of the Employee Plans pursuant to Subtitle 1 of Title IV of
ERISA.  To Seller's Knowledge, none of the Employee Plans has been the
subject of a reportable event (as defined in Section 4043 of ERISA) as to
which a notice would be required to be filed with the PBGC.  Each
Company, Seller or an Affiliate of Seller has paid in full all insurance
premiums due to the PBGC with regard to the Employee Plans for all
applicable periods ending on or before the Closing Date.
  
(e)  To Seller's Knowledge, the transactions contemplated hereby will not
result in any liability, (i) for the termination of or withdrawal from
any Employee Plan under Sections 4062, 4063, or 4064 of ERISA, (ii) for
any lien imposed under Section 302(f) of ERISA or Section 412(n) of the
Code, (iii) for any interest payments required under Section 302(e) of
ERISA or Section 412(m) of the Code, (iv) for any excise tax imposed by
Section 4971 of the Code, (v) for any minimum funding contributions under
Section 302(c)(11) of ERISA or Section 412(c)(11) of the Code, or (vi)
for withdrawal from any Multi- Employer Plan under Section 4201 of ERISA.
  
(f)  Except as disclosed on Schedule 2.14(f), each Company has complied
with the continuation coverage provisions of the Consolidated Omnibus
Budget Reconciliation Act of 1985 ("COBRA"), as amended, with respect to
all current employees and former employees of the Business and other
"qualified beneficiaries" (as defined in Code Section 4980B(g)(1) and
ERISA Section 607(3)).  To Seller's Knowledge, all current and former
Employee Plans that are "group health plans," as defined in Section
5000(b) of the Code, have been operated in conformance with the Medicare
as Secondary Payer provisions of the Social Security Act, and no person
is subject to liability under Section 5000(a) of the Code with respect to
any such Employee Plan.
  

(g)  The forms of all Employee Plans are in compliance with the
applicable terms of ERISA, the Code, and any other applicable laws,
including the Americans with Disabilities Act and the Family Medical
Leave Act, and such plans have been operated in compliance with such laws
and the written Employee Plan documents, except where such failures would
not have, and would not reasonably be expected to have, in the aggregate
a Material Adverse Effect on the Business.  Neither of the Companies nor,
to Seller's Knowledge, any fiduciary of an Employee Plan has violated the
requirements of Section 404 of ERISA. All required reports and
descriptions of the Employee Plans (including Internal Revenue Service
Form 5500 Annual Reports, Summary Annual Reports and Summary Plan
Descriptions) have been timely filed with the IRS, the United States
Labor Department, or any other state or federal agency and distributed,
and all notices required by ERISA or the Code or any other state or
federal law or any ruling or regulation of any state or federal
administrative agency with respect to the Employee Plans have been
appropriately given, except where such failures would not have, and would
not reasonably be expected to have, in the aggregate a Material Adverse
Effect on the Business.
  
(h)  Each Employee Plan which is intended to be qualified under Section
401(a) of the Code has received a favorable determination letter from the
IRS, except that no representation is given as to any Multi-Employer
Plans.  Each trust created under any Employee Plan has been determined to
be exempt from taxation under Section 501(a) of the Code.  Each of the
Employee Plans that is an Employee Welfare Benefit Plan (as defined in
Section 3(1) of ERISA) that utilizes a funding vehicle described in
Section 501(c)(9) of the Code or is subject to the provisions of Section
505 of the Code has been the subject of a notification by the IRS that
such funding vehicle qualifies for tax- exempt status under Section
501(c)(9) of the Code and/or that the plan complies with Section 505 of
the Code, unless the IRS does not as a matter of policy issue such
notification with respect to the particular type of plan, except that no
representation is given as to any Multi-Employer Plans.  With respect to
each Employee Plan, to Seller's Knowledge, no event has occurred which
will give rise to a loss of any intended tax consequence or to any tax
under Section 511 of the Code, except that no representation is given as
to any Multi- Employer Plans.
  
(i)  There is no material pending or, to Seller's Knowledge, threatened
Proceeding relating to any Employee Plan.  Neither of the Companies nor,
to Seller's Knowledge, any fiduciary of an Employee Plan has engaged in a
transaction with respect to any Employee Plan that, assuming the taxable
period of such transaction expired as of the date hereof, would subject
either Company or Purchaser to a tax or penalty imposed by either Section
4975 of the Code or Section 502(l) of ERISA or a violation of Section 406
of ERISA.  The transactions contemplated hereby will not result in the
potential assessment of a tax or penalty under Section 4975 of the Code
or Section 502(l) of ERISA nor result in a violation of Section 406 of
ERISA.
  
(j)  Each Company, Seller or an Affiliate of Seller has maintained
workers' compensation coverage on the Employees as required by applicable
state law for at least 30 days prior to the execution of this Agreement.
  
(k)  Except as required by Laws and as disclosed on Schedule 2.14(k), the
consummation of the Transactions contemplated hereby will not accelerate
the time of vesting or the time of payment, or increase the amount, of
compensation due to any Transferred Employee.  There are no contracts or
arrangements providing for payments that would subject either Company or
Purchaser to liability for tax under Section 4999 of the Code.
  
(l)  Except for the continuation coverage requirements of COBRA, neither
Company has obligations or potential liability for benefits to employees
following termination of employment or retirement under any of the
Employee Plans that are Employee Welfare Benefit Plans.

2.15 Compliance with Laws; Governmental Authorizations.

(a)  Except as set forth in Schedule 2.15(a):

(i)  Each Company is in compliance with each Law that is applicable to it
or to the conduct or operation of the Business or the ownership or use of
any of its assets included in the Acquired Assets, except any instances
of noncompliance that would not have, and would not reasonably be
expected to have, in the aggregate a Material Adverse Effect on the
Business;
            
(ii) To the Knowledge of Seller, neither Company has received any notice
or other communication (whether oral or written) from any Governmental
Authority or any other Person regarding (A) any actual, alleged,
possible, or potential violation of, or failure to comply with, any Law,
or (B) any actual, alleged, possible, or potential obligation on the part
of the Company to undertake, or to bear all or any portion of the cost
of, any remedial action of any nature, except in cases with respect to
which notice or communication either (x) has been resolved without any
liability resulting from such resolution being included in the Closing
Balance Sheet, or (y) will be retained by Seller as a Seller Liability
(and no amount will be accrued therefor in the Closing Balance Sheet).


(b)  Schedule 2.15(b) contains a complete and accurate list of each
Governmental Authorization that is held by each Company or that otherwise
relates to the Business or the Acquired Assets.  Schedule 2.15(b)
identifies the holder of each Governmental Authorization not held by
either Company that is used in the Business.  Each Governmental
Authorization listed or required to be listed in Schedule 2.15(b) is
valid and in full force and effect, except where the invalidity or
failure to be in full force and effect would not have, and would not
reasonably be expected to have, in the aggregate a Material Adverse
Effect on the Business.  Except as set forth in Schedule 2.15(b):

(i)  Each Company is in compliance with all of the terms and requirements
of each Governmental Authorization identified or required to be
identified in Schedule 2.15(b), except where such failure would not have,
and would not reasonably be expected to have, in the aggregate a Material
Adverse Effect on the Business.
            
(ii) To Seller's Knowledge, neither Company has received any notice or
other communication (whether oral or written) from any Governmental
Authority or any other Person regarding (A) any actual, alleged,
possible, or potential violation of or failure to comply with any term or
requirement of any Governmental Authorization, or (B) any actual,
proposed, possible, or potential revocation, withdrawal, suspension,
cancellation  termination of, or modification to any Governmental
Authorization, in each case which notice or communication has not been
resolved; and
            
(iii) all applications required to have been filed for the renewal of the
Governmental Authorizations listed or required to be listed in Schedule
2.15(b)  have been duly filed on a timely basis with the appropriate
Governmental Authorities, and all other filings required to have been
made with respect to such Governmental Authorizations have been duly made
on a timely basis with the appropriate Governmental Bodies, except where
the failure to make such filings would not and would not reasonably be
expected to have, in the aggregate a Material Adverse Effect on the
Business.

Except as disclosed in Schedule 2.15(a), the Governmental Authorizations
listed in Schedule 2.15(b) collectively constitute all of the
Governmental Authorizations necessary to permit the Companies to lawfully
conduct and operate the Business as of the date hereof and to permit the
Companies to own and use its assets in the manner in which it owns and
uses such assets as of the date hereof, except for such omissions that
would not have, and would not reasonably be expected to have, in the
aggregate, a Material Adverse Effect on the Business.

2.16 Legal Proceedings; Orders.

(a)  Except as set forth in Schedule 2.16(a) there is no pending or, to
Seller's Knowledge, threatened Proceeding:

(i)  by or against either Company or that otherwise relates to or would
reasonably be expected to affect the Business or any of the Acquired
Assets, except such Proceedings that would not reasonably be expected to
have a Material Adverse Effect on the Business; or
            
(ii) that challenges, or that will or could reasonably be expected to
prevent, delay, make illegal, or otherwise interfere with, any of the
transactions contemplated hereby.

(ii) to the Knowledge of Seller, no employee or agent of either Company,
who, in the case of an employee, is a Transferred Employee and, in the
case of an agent, is a party to a contract that is a Company Liability,
is subject to any Order that prohibits such employee or agent from
engaging in or continuing any conduct, activity, or practice relating to
the Business in any material respect.

4.05 Notice of Developments.  Seller will give prompt written notice
to Purchaser of any material adverse development affecting the Business
and any breach of its representations and warranties contained in Article
II hereof.

4.06 Exclusivity.  Seller will not solicit, initiate, encourage or accept
any proposal or offer from any Person relating to the acquisition of the
Shares or any of the Acquired Assets (including any acquisition
structured as a merger, consolidation, or share exchange) other than in
the Ordinary Course of Business and neither Seller, its officers or any
other representatives of Seller shall participate in any discussions or
negotiations regarding, furnish any information with respect to, assist
or participate in, or facilitate in any other manner any effort or
attempt by any person to do or seek any of the foregoing.

4.07 New Transferred Projects and Bids.  After the date hereof until
the Closing Date, Seller will promptly notify Purchaser of (a) any bid
made by Seller that would be a Transferred Project if such bid was
accepted and (b) the acceptance or award of any bid made by Seller which
shall become a Transferred Project.  To the extent that Purchaser is not
also making a bid on any project, Seller will cause the Companies to
consult with Purchaser on any such bid in advance of submitting such bid
if the respective bid represents work or services to be provided by the
Companies (excluding subcontracted work or services provided by a third
party) of more than One Million Dollars ($1,000,000).

4.08 Establishment of Relationships.  Upon the request of Purchaser,
Seller will cause the Companies, at Purchaser's expense, to use their
reasonable efforts to assist the Purchaser in establishing relationships
with representatives and agents in foreign countries comparable to those
to which the Companies are currently parties and which relate to the
Business.

4.09 Updating Representations and Warranties. From time to time prior to
the Closing, Seller shall promptly supplement or amend any of its
representations and warranties under Article II which apply to the period
after the date hereof by delivering an updated Schedule to Purchaser with
respect to any change in fact occurring hereafter or event arising
hereafter which would render any such representation or warranty, if made
after the date of this Agreement, inaccurate or incomplete.  Such
supplement or amendment to Seller's representations and warranties
contained in an updated schedule shall be deemed to modify the
representations and warranties of Seller, and no such supplement or
amendment, or the information contained in an updated Schedule, shall
constitute a breach of a representation or warranty of Seller.  If the
information in such supplement or amendment, together with the
information in any or all of the supplements or amendments previously
provided by Seller or otherwise in the possession of Purchaser indicates
to Purchaser that the Business has suffered or is reasonably likely to
suffer a Material Adverse Effect, Purchaser may terminate this Agreement
within fifteen (15) days after the receipt of such supplement or
amendment, provided that if it appears to Purchaser that the Material
Adverse Effect may be cured within thirty (30) days from the date the
Purchaser received such supplement or amendment (the "Cure Period") and
the cure is promptly commenced by the Seller, Purchaser may not terminate
this Agreement under this Section until the day after the Cure Period
expires.

4.10 Hedge Contract.  Seller has a hedge contract with Harris Bank &
Trust Company (the "Bank") with respect to the South African currency. 
The Bank has advised Seller that it will not permit the assignment of
these contracts to Norment or Purchaser.  Within ten (10) Business Days
after the Closing, Seller and Purchaser shall reasonably cooperate with
each other to effect a close out all of its hedge contracts with respect
to the South African currency in the most efficient manner reasonably
possible, and either (i) Seller will pay Purchaser the net profit (after
taking into account the costs and expenses incurred by Seller in
connection with such hedge contracts), or (ii) Purchaser will pay Seller
the net loss (after taking into account the costs and expenses incurred
by Seller in connection with such hedge contracts).

4.11 Covenant Not to Compete; Non-Solicitation of Transferred
Employees.  

(a)  For a period of five (5) years after the Closing Date, neither
Seller nor any Affiliate of Seller shall directly or indirectly, own,
manage, operate, control, act as consultant or advisor to, render any
services for, have any financial interest (other than as a creditor) in,
or otherwise be connected in any manner with the ownership, management,
operation, or control of any Person, firm, partnership, corporation, or
other entity (a "Competitor") that is engaged in any business that
directly competes with the Business; provided that, notwithstanding any
of the foregoing, nothing contained in this Section 4.11 shall (i)
restrict the ability of Seller and its Affiliates to manufacture,
fabricate, install or service glass products, including the sale of
bullet resistant glass for or to a Competitor or any customer of the      
Business, (ii) impose any restriction on any party that may acquire       
assets, properties or a business from Seller or its Affiliates, or (iii)
prevent Seller or any Affiliate from acquiring or holding equity
securities of any publicly traded company if the amount of such
securities represents less than 1% of the outstanding capital stock of
such company.  All of the foregoing provisions are reasonable and are
necessary to protect and preserve the value of the Shares to be acquired
by Purchaser under this Agreement and to prevent any unfair advantage
being conferred on Seller or its Affiliates.  For a period of two (2)
years after the Closing Date, neither Seller nor any Affiliate of Seller
shall make any direct sales to the U. S. Department of State for use and
installation in embassies of fabricated and finished window or door
systems using bullet resistant glass, excluding field constructed
curtainwall.
                    
(b)  Prior to Closing, Seller shall not, and shall cause its Affiliates
other than the Companies not to directly or indirectly solicit any of the
Transferred Employees to be hired or employed by Seller or such
Affiliates other than in the Business prior to the Closing.  For the two
(2) years after the Closing Date, Seller shall not, and Seller shall
cause its Affiliates not to, directly or indirectly solicit or hire any
of the Transferred Employees so long as they are employed by the
Companies or Purchaser.  Upon Closing, the Transferred Employees shall be
deemed employees of the Companies.

4.12 Administrative Services.  At the Closing, Seller will cause its
Affiliate, Harmon Ltd., to enter into the administrative services
agreement in form and substance substantially identical to Exhibit B
attached hereto (the "Administrative Services Agreement") with the
Companies, and the Purchaser shall cause the Companies to enter into the
Administrative Services Agreement at Closing.

4.13 Vesting of Benefits under Certain Employee Plans.  Seller will
cause to vest on the Closing Date all contributions to the Apogee
Enterprises, Inc. Retirement Plan (Plan No. 001) and Apogee Enterprises,
Inc. Tax Relief Investment Plan (Plan No. 005) with respect to each
Transferred Employee, which contributions have been accrued as of the
Closing Date and will make payment of all such contributions to such
Employee Plans on or promptly after the Closing Date.

                                ARTICLE V
                          COVENANTS OF PURCHASER

      Purchaser covenants and agrees with Seller that, at all times from
and after the date hereof until the Closing with respect to Sections 5.01
through 5.04 hereof, and as of the Closing and thereafter with respect to
Sections 5.05 through 5.10 hereof, Purchaser will comply with all
covenants and provisions of this Article V, except to the extent Seller
may otherwise consent or waive in writing. 

5.01 Hart-Scott-Rodino Act.  As soon as practicable after the date
of this Agreement, Purchaser agrees to make any filings required under
the Hart-Scott-Rodino Act.  Purchaser will furnish to Seller such
necessary information and reasonable assistance as Seller may reasonably
request in connection with its preparation of any additional necessary
filings or submissions to any governmental agency, including, without
limitation, any additional filings necessary under the Hart-Scott-Rodino
Act. 

5.02 Notice of Developments.  Purchaser will give prompt written notice
to Seller of any material adverse development affecting Purchaser or any
breach of any of its representations and warranties in Article III
hereof.

5.03 Fulfillment of Conditions.  Purchaser covenants and agrees with
Seller that, at all times from and after the date hereof until the
Closing, Purchaser will proceed diligently and in good faith to (a)
satisfy each condition to the obligations of Purchaser contained in this
Agreement, (b) obtain the financing contemplated by the Financing
Commitment and the bonding contemplated by the Bonding Commitment, and
(c) obtain all security clearances and other licenses (including
construction licenses) necessary for performance of the Contracts for the
Transferred Projects (or the subcontract thereof) to Purchaser as
contemplated by this Agreement, and will not take or fail to take any
action that is reasonably be expected to (or the omission of which would
be reasonably expected to) result in the nonfulfillment of any such
condition.

5.04 Payment and Performance Bonds.  Purchaser shall use reasonable
commercial efforts to provide the individual standard subcontract payment
and performance bonds as provided in Schedule 5.04 hereto (the "Bonding
Condition").

5.05 Offer of Employment to Employees.  Purchaser shall, as of the
Closing Date, offer to employ (on substantially similar terms as such
Employees are currently employed in the Business) all of the Employees
listed on Schedule 2.20 who are employed in the Business as of the
Closing and such other persons who are hired in the ordinary course of
business after August 29, 1998 and are employed in the Business as of the
Closing Date, including Employees who are on sick leave, military leave
or other duly authorized leave of absence.  Each Employee who accepts
Purchaser's offer of employment is herein referred to as a "Transferred
Employee" and all such employees are herein referred to as "Transferred
Employees;" provided, however, the persons listed on Schedule 2.20 as
remaining with Seller or its Affiliates shall not be Transferred
Employees.  Purchaser shall not terminate a Transferred Employee (except
for cause) for a period of sixty (60) days after employment of such
Transferred Employee.  To effect the foregoing transition, upon Closing
the Transferred Employees shall be deemed employees of the Companies.

5.06 Employee Benefits.  Purchaser will  provide the Transferred
Employees hired by Purchaser under Section 5.05 with substantially the
same employee benefits as provided to its other employees which shall be
reasonably comparable to the Employee Plans.  Purchaser will insure that,
to the extent permitted by law, such benefits provided to the Transferred
Employees treat employment with the Companies or Seller's Affiliates
prior to the Closing Date the same as employment with Purchaser from and
after the Closing Date for purposes of eligibility, vesting and benefit
accrual under such benefit plans.  

5.07 Warranty and Other Work. For a period of five (5) years after
Closing and upon the request of Seller, Purchaser agrees to perform
warranty work or repairs on any project of the Business that is not a
Transferred Project.  Purchaser will promptly and diligently perform any
such warranty work or repairs requested by Seller.  Purchaser will charge
Seller and Seller will pay Purchaser for any such warranty work or
repairs performed by Purchaser the actual cost (under Purchaser's
customary costing formula) incurred by Purchaser to perform such work or
repairs plus 5% thereof. In the event that Purchaser receives a claim
from any customer of a breach of contractual warranty with respect to
work performed prior to Closing other than with respect to any
Transferred Project, Purchaser shall promptly notify Seller.  In the
event Seller and such customer do not resolve such claim within a
reasonable period after its submission, a responsible officer of Seller
and Purchaser will confer in good faith to reach a mutually acceptable
resolution of the claim.  In the event Seller and Purchaser fail to reach
a mutually acceptable resolution within thirty (30) days after such
representatives first meet, then either party may request that the extent
of Seller's responsibility be determined by binding arbitration in the
manner contemplated by Section 8.04(b).

5.08 Access to Books and Records; Personnel.  For a period of seven
(7) years after the Closing Date, Purchaser shall, upon the request of
Seller, provide Seller or its Representatives reasonable access to the
Books and Records of the Companies for any period prior to the Closing
Date and permit the taking of copies therefrom.  So long as Seller has a
right of access under this Section 5.08, Purchaser will provide Seller at
least thirty (30) days prior written notice before destroying such Books
and Records or otherwise make such Books and Records not readily
accessible by Seller so that Seller may elect to receive such Books and
Records.  For a period of seven (7) years after the Closing, Purchaser
shall make personnel of the Companies reasonably available to Seller to
provide information relating to any of the Seller Liabilities.   Seller
shall reimburse Purchaser its reasonable out of pocket costs to provide
such assistance.

5.09 Multi-Employer Plan.  At Closing and after Closing, Purchaser shall,
and Purchaser shall cause the Companies to, execute and deliver such
agreement or agreements consistent with ERISA Section4204 and take all
actions as may be required by such agreements and by ERISA Section 4204 
to the extent that executing such agreements and taking such reasonable 
actions would prevent the Seller (or any Affiliate of the Seller) from 
incurring any partial or complete withdrawal liability to any 
Multiemployer Plan as a result of the transactions contemplated by 
this Agreement if such transactions were to be deemed to constitute 
an asset sale rather than a stock purchase.  Purchaser and Companies 
shall indemnify Seller (and Affiliates of the Seller) from any 
withdrawal liability that may arise to the extent that such withdrawal 
liability is the result of Purchaser's and/or Companies' failure to 
execute and deliver such agreement or agreements consistent with 
ERISA Section4204 and take such reasonable actions
as may be required by such agreements and by ERISA Section4204.

5.10 Voice Track.  After Closing, Purchaser shall, and shall cause
the Companies to, (a) promptly transfer to Seller all amounts received by
Purchaser or either of the Companies in respect to accounts receivable
for the Voice Track business of Norment which are Excluded Assets, and
(b) provide Seller reasonable assistance in billing and collecting the
accounts receivable for the Voice Track business of Norment, provided
that neither Purchaser nor either of the Companies shall be required to
commence any Proceeding to effect such collections.

adjustments provided for in Section 8.02(c), Seller will indemnify and
hold harmless the Purchaser and its representatives, shareholders,
subsidiaries and Affiliates (collectively, the "Purchaser Indemnified
Parties") and will reimburse the Purchaser Indemnified Parties for any
loss, liability, claim, damage, expense (including reasonable costs of
investigation and defense and reasonable attorneys fees and expenses to
the extent defense is not provided by Seller and, with respect to matters
arising out of Contracts that neither constitute Company Liabilities nor
relate to Transferred Projects, the reasonable time charges for
participation in the defense of such matters by Purchaser's personnel) or
diminution of value, whether or not involving a third party claim     
(collectively, "Losses"), arising from or in connection with:
                      
(i) any breach of any representation or warranty made by Seller in

commissions or similar payments based upon any agreement or understanding
alleged to have been made by any such Person with Seller or either of the
Companies (or any Person acting on their behalf) in connection with any
of the transactions contemplated by this Agreement;

(iv) any product or component thereof sold and delivered by or any
services provided by, the Companies, prior to the Closing Date other than
in connection with the Transferred Projects and subject to the provisions
of Section 5.07 hereof;

(v)  all Seller Liabilities; and
                                      
(vi) any claims or threatened claims arising out of the actions or
inactions of either of the Companies, Seller or its other Affiliates with
respect to the Business prior to the Closing Date, excluding however, any
claims arising or resulting from or related to the Transferred Projects

either of the Companies, Seller or its other Affiliates taken or failed
to be taken prior to the Closing Date or from actions or inactions of     
the Companies, Purchaser or its Affiliates taken or failed to be taken on
or after the Closing Date.

The Losses described in clauses (i) and (ii)(A) above are collectively    
referred to herein as "Purchaser Losses".

(b)  Seller shall be liable to the Purchaser Indemnified Parties for any
Purchaser Losses only if the aggregate amount of all Purchaser Losses
exceeds $500,000 (the "Deductible"), in which case Seller shall only be
obligated to indemnify Purchaser for Purchaser Losses in excess of the
Deductible and, then, only to the extent indemnification payable by
Seller with respect to Purchaser Losses under this Section 8.02 does not
in the aggregate exceed $5,000,000.
      
(c)  Notwithstanding anything contained herein to the contrary, the
amount for which a Purchaser Indemnified Party is entitled to  
indemnification hereunder for Purchaser's Losses shall be reduced by

insurance policies, insurance loss funds or insurance deposits (net     
of deductibles and incidental expenses) and further reduced by     
recovery of any setoffs or counterclaims realized by the Purchaser     
Indemnified Party that are measurable in dollars with reasonable
certainty (net of cost and expenses of recovering such amounts).
      
(d)  For the purposes of determining Purchaser Losses, the Seller's
representations and warranties in Article II hereof, shall be deemed to
be made without reference to any materiality qualifications, including,
without limitation Material Adverse Effect qualifications.

(e)  Any indemnification payable by Seller under this Section 8.02 shall
be, to the extent permitted by law, an adjustment to Purchase Price.

8.03 Indemnification by Purchaser.  Purchaser will indemnify and hold
harmless Seller and its officers, directors, employees, agents,
shareholders and Affiliates (collectively the "Seller Indemnified
Parties") and will reimburse the Seller Indemnified Parties for any loss,
liability, claim, damage, expense (including reasonable costs of
investigation and defense and reasonable attorneys fees and expenses to
the extent defense is not provided by Purchaser and, with respect to
matters arising out of Contracts that either constitute Company
Liabilities or relate to Transferred Projects, the reasonable time
charges for participation in the defense of such matters by Seller's
personnel) or diminution of value, whether or not involving a third party
claim, arising from or in connection with:
                      
(a) any breach of any representation or warranty made by Purchaser in
Article III of this Agreement;
      
(b) any breach of any covenant or obligation of Purchaser in this
Agreement;

or similar payments based upon any agreement or understanding alleged to
have been made by any such Person with Purchaser (or any Person acting on
its behalf) in connection with any of the transactions contemplated by
this Agreement;

(d) any product or component thereof sold and delivered, or any services
provided by, the Companies, on or after the Closing Date;

(e) all Company Liabilities;
                                          
(f)  any claims or threatened claims arising out of the actions or
inactions of either of the Companies, Purchaser or its other Affiliates
with respect to the Business on or after the Closing Date, and 
                 
(g)  any claims arising or resulting from or related to the Transferred
Projects regardless of whether such claims result from actions or
inactions of either of the Companies, Seller or its other Affiliates
taken or failed to be taken prior to the Closing Date, from consummation
of the transactions contemplated by this Agreement, from actions taken by
Seller or any of its Affiliates after Closing pursuant to Purchaser's
request under Section 1.01(a), or from actions or inactions of the
Companies, Purchaser or its other Affiliates  taken or failed to be taken
on or after the Closing Date.
                 
At Closing, Purchaser will cause the Companies to provide an
indemnification agreement in form and substance substantially identical
to Exhibit C attached hereto with joint and several liability for the
Companies containing the terms of this Article VIII and covering the
matters set forth in clauses (d) through (g) above.

8.04 Method of Asserting Claims.  As used herein, an "Indemnified Party"
shall refer to a Purchaser Indemnified Party or a Seller Indemnified
Party, as applicable; the "Notifying Party" shall refer to the party
hereto whose Indemnified Parties are entitled to indemnification
hereunder; and the "Indemnifying Party" shall refer to the party hereto
obligated to indemnify such Notifying Party's Indemnified Parties.

(a) In the event that any of the Indemnified Parties is made a defendant
in or party to any action or proceeding, judicial or administrative,
instituted by any third party for the liability or the costs or expenses
of which are Losses (any such third party action or proceeding being
referred to as a "Claim"), the Notifying Party shall give the
Indemnifying Party prompt notice thereof.  The failure to give such
notice shall not affect any Indemnified Party's ability to seek
reimbursement unless such failure has materially and adversely affected
the Indemnifying Party's ability to defend successfully a Claim.  The
Indemnifying Party shall be entitled to contest and defend such Claim;
provided, that the Indemnifying Party (i) has a reasonable basis for
concluding that such defense may be successful and (ii) diligently
contests and defends such Claim.  Notice of the intention so to contest
and defend shall be given by the Indemnifying Party to the Notifying
Party within 20 Business Days after the Notifying Party's notice of such
Claim (but, in all events, at least five Business Days prior to the date
that an answer to such Claim is due to be filed).  Such contest and
defense shall be conducted by reputable attorneys engaged by the
Indemnifying Party.  The Notifying Party shall be entitled at any time,
at its own cost and expense (which expense shall not constitute a Loss    
unless the Notifying Party reasonably determines that the Indemnifying
Party is not adequately representing or, because of a conflict of
interest, may not adequately represent, any interests of the Indemnified
Parties, and only to the extent that such expenses are reasonable) to
participate in such contest and defense and to be represented by
attorneys of its or their own choosing.  If the Notifying Party elects to
participate in such defense, the Notifying Party will cooperate with the
Indemnifying Party in the conduct of such defense.  Neither the Notifying
Party nor the Indemnifying Party may concede, settle or compromise any
Claim without the consent of the other party, which consents will not be
unreasonably withheld. Notwithstanding the foregoing, (i) if a Claim
seeks equitable relief or (ii) if the subject matter of a Claim relates
to the ongoing business of any of the Indemnified Parties, which Claim,   
if decided against any of the Indemnified Parties, would materially     
and adversely affect the ongoing business or reputation of any of the
Indemnified Parties, then, in each such case, the Indemnified Parties
alone shall be entitled to contest, defend and settle such Claim in the
first instance and, if the Indemnified Parties do not contest, defend or
settle such Claim, the Indemnifying Party shall then have the right to
contest and defend (but not settle) such Claim.

(b)  In the event any Indemnified Party shall have a claim against any
Indemnifying Party that does not involve a Claim, the Notifying Party
shall deliver a notice of such claim with reasonable promptness to the
Indemnifying Party.  If the Indemnifying Party notifies the Notifying
Party that it does not dispute the claim described in such notice or
fails to notify the Notifying Party within 30 days after delivery of such
notice by the Notifying Party whether the Indemnifying Party disputes the
claim described in such notice, the Loss in the amount specified in the
Notifying Party's notice will be conclusively deemed a liability of the
Indemnifying Party and the Indemnifying Party shall pay the amount of
such Loss to the Indemnified Party on demand.  If the Indemnifying Party
has timely disputed its Liability with respect to such claim, the chief
executive officers of each of the Indemnifying Party and the Notifying
Party will proceed in good faith to negotiate a resolution of such
dispute, and if not resolved through the negotiations of such Chief
Executive Officers within 60 days after the delivery of the Notifying
Party's notice of such claim, such dispute shall be resolved fully and
finally in Minneapolis, Minnesota by an arbitrator selected pursuant to,
and an arbitration governed by, the Commercial Arbitration Rules of the   
American Arbitration Association.  The arbitrator shall resolve the     
dispute within 30 days after selection and judgment upon the award
rendered by such arbitrator may be entered in any court of competent     
jurisdiction.

(c)  After the Closing, the rights set forth in this Article VIII shall
be each party's sole and exclusive remedies against the other party
hereto for misrepresentations or breaches of covenants contained in this
Agreement.  Notwithstanding the foregoing, nothing herein shall prevent
any of the Indemnified Parties from bringing an action based upon actual
and knowing fraud or other intentional breach of an obligation of or with
respect to either party in connection with this Agreement and the Related
Documents.  In the event such action is brought, the prevailing party's
attorneys' fees and costs shall be paid by the nonprevailing party.

                            ESCROW AGREEMENT


      This Escrow Agreement (this "Agreement") is made and entered into
as of November 10, 1998 by and among APOGEE ENTERPRISES, INC., a
Minnesota corporation ("Seller"), COMPUDYNE CORPORATION, a Nevada
corporation ("Purchaser"), and THE BANK OF NEW YORK, as escrow agent
("Escrow Agent").

                          STATEMENT OF PURPOSE
                                    
      WHEREAS, Purchaser and Seller are entering into this Agreement
pursuant to the terms of that Stock Purchase Agreement dated as of
November 10, 1998 (the "Purchase Agreement").

      WHEREAS, pursuant to the Purchase Agreement, Purchaser is required
to deposit certain funds into escrow pursuant to this Agreement.

                               AGREEMENT

      Now, therefore, in consideration of the premises and the mutual
promises herein made, and in consideration of other good and valuable
consideration, the receipt and sufficiency whereof is hereby
acknowledged, the parties hereby agree as follows:

1.   Definition of Terms.  Terms not otherwise defined herein shall have
the meaning ascribed to such terms in the Purchase Agreement.  The Escrow
Agent shall not be responsible for any other provisions of the Purchase
Agreement.

2.  Appointment and Acceptance.  Purchaser and Seller hereby appoint
Escrow Agent as escrow agent for the purposes and upon the terms and
conditions set forth in this Agreement.  Escrow Agent hereby accepts such
appointment and agrees to act as escrow agent hereunder and to hold,
invest and dispose of any funds received by it hereunder in accordance
with the terms and conditions set forth in this Agreement.

3.  Deposit of Escrowed Funds.  On the date hereof, Purchaser shall,
as partial payment of the Purchase Price, deliver to Escrow Agent for
deposit in escrow pursuant to the provisions of this Agreement, a wire
transfer of immediately available funds in the amount of $250,000 (the
"Escrowed Funds").

4.  Delivery of Escrow Funds upon Termination relating to Financing
or Bonding Contingencies.  In accordance with paragraph 6 below, the
Escrow Agent shall deliver to Purchaser the Escrowed Funds upon receipt
of notice from Seller to the Escrow Agent and Purchaser that the Purchase
Agreement has been terminated due to a failure to satisfy the Financing
Condition or the bonding Condition under the Purchase Agreement.

5.   Delivery of Escrowed Funds in Other Circumstances.  In accordance
with paragraph 6 below, the Escrow Agent shall deliver to Purchaser the
Escrowed Funds upon receipt of notice from Purchaser to the Escrow Agent
and Seller that the Purchase Agreement has been terminated for reasons
other than due to a failure to satisfy the Financing Condition or the
Bonding Condition under the Purchase Agreement.

6.   Contest of a Claim to Escrow Funds.  

(a)  If, at any time Seller or Purchaser shall claim that it is entitled
to payment of all or a portion of the Escrowed Funds (a "Right of
Payment"), such party shall give notice of such Right of Payment (the
"Notice of Payment") to the other party and the Escrow Agent.  The Notice
of Payment shall be an affidavit describing the event or circumstances
giving rise to the Right of Payment, specifying the amount of the
Escrowed Funds requested and certifying that the Notice of Payment is
being submitted in good faith.

(b)  If Escrow Agent shall have received a Notice of Payment, Escrow
Agent shall promptly deliver a copy thereof to the other party hereto. 
Within ten (10) Business Days ("Dispute Period") after delivery by Escrow
Agent of a copy of such Notice of Payment to such other party, such other
party may deliver to Escrow Agent a written notice (the "Notice of
Dispute") disputing the request for payment of Escrowed Funds stated in
the Notice of Payment.  The Notice of Dispute shall be an affidavit
specifying the amount being disputed (the "Disputed Amount"), describing
in reasonable detail the reasons for such dispute and certifying that the
Notice of Dispute is being submitted in good faith.  If Escrow Agent has
not received a Notice of Dispute prior to the expiration of Dispute
Period referred to above, then Escrow Agent shall immediately pay to such
requesting party, by check or wire transfer of immediately available
funds, the full amount of the Escrowed Funds requested in the Notice of
Payment. If Escrow Agent has received a Notice of Dispute during the
Dispute Period which disputes in part the request for payment of Escrowed
Funds stated in the Notice of Payment, then Escrow Agent shall, following
receipt of such Notice of Dispute, immediately pay to such requesting
party, by check or wire transfer of immediately available funds, the
amount, if any, of Escrowed Funds requested in the Notice of Payment
which is in excess of the Disputed Amount. 

(c)  If Escrow Agent receives a Notice of Dispute, Escrow Agent shall
promptly deliver a copy of the Notice of Dispute to the other party
hereto, and shall not deliver the Disputed Amount until Escrow Agent
shall have received one of the following:

(i)  A certified copy of an order, decree or judgment issued or rendered
by a court of competent jurisdiction, which order, decree or judgment has
been finally affirmed on appeal or which by lapse of time or otherwise is
no longer subject to appeal (a "Final Decision")directing the
distribution of the Escrow Funds; or

(ii) A joint written direction executed by Purchaser and Seller directing
the distribution of the Escrowed Funds.

Upon receipt of either (i) or (ii) above, Escrow Agent shall immediately
deliver the Escrowed Funds to the proper party in accordance therewith.

7.   Investment of Escrowed Funds.  Escrow Agent shall invest the
Escrowed Funds, from time to time, in 30-day United States Treasury
obligations or certificates of daily deposit having a maturity not to
exceed 30 days, any governmental mutual funds, or such other investments
mutually designated by Purchaser and Seller.  The proceeds of all
investments made hereunder shall be distributed in accordance with this
Agreement.  Escrow Agent shall deliver monthly statements to Purchaser
and Seller in accordance with Escrow Agent's regular practice; the
parties hereby agree that, except for the foregoing, Escrow Agent shall
have no obligations to monitor, or advise the parties with respect to,
such investments.  All interest or other income earned on the Escrow
Funds shall become and be retained and disbursed as part of the Escrow
Funds.  The party hereunder that receives the interest or other income
shall be responsible for filing all necessary tax returns for any
interest or other income paid or attributed to it hereunder and shall pay
any taxes thereon.

8.   Termination of Escrow.  On the Closing Date, Purchaser and Seller
shall direct the Escrow Agent to pay Seller the Escrow Funds and, upon
such payment, the escrow under this Agreement shall terminate.  In the
event of a termination of the Purchase Agreement, Escrow Agent shall
disburse the Escrowed Funds in accordance with the provisions of
paragraphs 4 through 6 hereof, whereupon the escrow under this Agreement
shall terminate. 

9.   No Liens on Escrowed Funds.  During the term of this Agreement,
each of Purchaser and Seller agree to keep the Escrowed Funds free and
clear of all liens, claims, encumbrances, levies, garnishments or other
attachments arising with respect to it.

10.  Notices.  Any notices or other communication required to be sent
or given hereunder by any of the parties shall in every case be in
writing and shall be deemed properly served if (a) delivered personally,

writing by both Purchaser and Seller, provided that Escrow Agent shall
first be indemnified to its satisfaction with respect to any of its costs
or expenses which might be involved.

14.  Resignation of Escrow Agent.  Escrow Agent, or any successor,
may resign at any time upon giving written notice, thirty (30) days
before such resignation shall take effect, to Purchaser and Seller.  In
the event Escrow Agent shall resign or be unable to serve, it shall be
succeeded by such bank or trust company as Purchaser and Seller shall
appoint, or if no appointment is made, by a bank or trust company
appointed by a court of competent jurisdiction.  In the absence of a
successor so appointed by Purchaser and Seller, Escrow Agent may petition

upon any court order, or the delivery thereof shall be stayed or enjoined
by an order of court, or any order, judgement or decree shall be made or
entered by any court order affecting the property deposited under this
Agreement, or any part thereof, Escrow Agent is hereby expressly
authorized in its sole direction, to obey and comply with all writs,
orders or decrees so entered or issued, which it is advised by legal
counsel of its own choosing is binding upon it, whether with or without
jurisdiction, and in case Escrow Agent obeys or complies with any such
writ, order or decree it shall not be liable to any of the parties hereto
or to any other person, firm or corporation, by reason of such compliance
notwithstanding such writ, order or decree be subsequently reversed,
modified, annulled, set aside or vacated.

(c)  In case said Escrow Agent becomes involved in litigation on account
of this deposit or of this Agreement, it shall have the right to retain
counsel and shall have a lien on the property deposited hereunder for any
and all costs, attorneys' fees, charges, disbursements, and expenses in

parties hereto jointly and severally agree to pay to said Escrow Agent on
demand, its reasonable charges, counsel and attorneys' fees,
disbursements, and expenses in connection with such litigation.

this escrow until such time as said conflicting demands shall have been
withdrawn or the rights of the respective parties shall have been settled
by court adjudication, arbitration, joint order or otherwise.

herein.

19.  Amendment.  This Agreement cannot be terminated, altered or amended
except pursuant to an instrument in writing signed by Purchaser, Seller
and Escrow Agent.

20.  Enforceability.  If any provision of the Agreement shall be held
invalid or unenforceable, such invalidity or unenforceability shall
attach only to such provision and shall not in any manner affect or
render invalid or unenforceable any other provision of this Escrow
Agreement, and the Agreement shall be carried out as if any such invalid
or unenforceable provision were not contained herein.

21.  Counterparts.  This Agreement may be executed in any number of
counterparts, each of which shall be deemed on original and all of which

issuance of a final, non-appealable order or judgment by a court of
competent jurisdiction, the prevailing party's legal fees and related
expenses shall be paid by the non-prevailing party.  The determination of

Companies, or (ii) September 1, 1999 (the "Termination Date").

3.   Extension or Sale.  If the Companies still require the Services
after September 1. 1999, and the hardware, software, manuals and other
items used in providing those services are still being utilized within

services are not being utilized within the Provider, the Companies may
purchase the hardware, software, manuals and other items used in

limitation, breach of contract, breach of warranty, negligence, strict
liability, misrepresentations and other torts.

2.1.1  Revolving Loan Commitment.  Each Bank will make loans on a
revolving basis ("Revolving Loans") from time to time until the

as the Company may request from all Banks; provided that the Revolving
Outstandings will not at any time exceed the lesser of (x) the Revolving
Commitment Amount and (y) the Borrowing Base.

2.1.2  Term Loan Commitment.  Each Bank agrees to make a loan to the
Company (each such loan, a "Term Loan") on the Closing Date in such
Bank's Pro Rata Share of $11,500,000.  The commitments of the Banks to

2.2  Loan Procedures.

2.2.1  Various Types of Loans.  Each Revolving Loan shall be, and each
Term Loan may be divided into tranches which are, either a Base Rate
Loan or a Eurodollar Loan (each a "type" of Loan), as the Company shall
specify in the related notice of borrowing or conversion pursuant to
Section 2.2.2 or 2.2.3.  Eurodollar Loans having the same Interest Period
are sometimes called a "Group" or collectively "Groups".  Base Rate Loans
and Eurodollar Loans may be outstanding at the same time, provided that
not more than five different Groups of Eurodollar Loans shall be
outstanding at any one time.  All borrowings, conversions and repayments
of Revolving Loans shall be effected so that each Bank will have a pro
rata share (according to its Pro Rata Share) of all types and Groups of
Loans. 

2.2.2  Borrowing Procedures. (a) The Company shall give written notice or
telephonic notice (followed immediately by written confirmation thereof)
to the Agent of each proposed borrowing not later than (a) in the case of
a Base Rate borrowing, 11:00 A.M., Chicago time, on the proposed date of
such borrowing, and (b) in the case of a Eurodollar borrowing, 11:00
A.M., Chicago time, at least three Business Days prior to the proposed
date of such borrowing.  Each such notice shall be effective upon receipt
by the Agent, shall be irrevocable, and shall specify the date, amount
and type of borrowing and, in the case of a Eurodollar borrowing, the
initial Interest Period therefor.  Promptly upon receipt of such notice,
the Agent shall advise each Bank thereof. Not later than 1:00 P.M.,
Chicago time, on the date of a proposed borrowing, each Bank shall
provide the Agent at the office specified by the Agent with immediately
available funds covering such Bank's Pro Rata Share of such borrowing
and, so long as the Agent has not received written notice that the
conditions precedent set forth in Section 11 with respect to such
borrowing have not been satisfied, the Agent shall pay over the funds
received by the Agent to the Company on the requested borrowing date. 
Each borrowing shall be on a Business Day.  Each Base Rate borrowing
shall be in an aggregate amount of at least $50,000 and an integral
multiple of $50,000, and each Eurodollar borrowing shall be in an
aggregate amount of at least $300,000 and an integral multiple of
at least $100,000. 

(b)  Each Subsidiary Borrower hereby designates Compudyne as its
representative and agent on its behalf for the purposes of issuing
notices of borrowing and conversion notices, giving instructions with
respect to the disbursement of proceeds of the Loans, selecting interest
rate options, requesting Letters of Credit, giving and receiving all
other notices and consents hereunder or under any of the other Loan
Documents and taking all other actions (including in respect of
compliance with covenants and with respect to any agreement for any
amendments, modifications, consents and waivers regarding this Agreement
or any other Loan Document) on behalf of any Subsidiary Borrower under
the Loan Documents.  Compudyne hereby accepts such appointment.  The
Agent and each Bank may regard any notice or other communication pursuant
to any Loan Document from Compudyne as a notice or communication from all
of the Companies, and may give any notice or communication required to be
given to any Subsidiary Borrower hereunder to Compudyne on behalf of such
Subsidiary Borrower.  Each Subsidiary Borrower agrees that each notice,
election, representation, warranty, covenant, agreement and undertaking
made on its behalf by Compudyne shall be deemed for all purposes to have
been made by such Subsidiary Borrower and shall be binding upon and
enforceable against such Subsidiary Borrower to the same extent as if the
same had been made directly by such Subsidiary Borrower.

2.2.3 Conversion and Continuation Procedures.  (a) Subject to Section
2.2.1, the Company may, upon irrevocable written notice to the Agent in
accordance with clause (b) below:

(i)  elect, as of any Business Day, to convert any Loans(or any part
thereof in an aggregate amount not less than $300,000 or a higher
integral multiple of $100,000) into Loans of the other type; or

(ii)  elect, as of the last day of the applicable Interest Period, to
continue any Eurodollar Loans having Interest Periods expiring on such
day (or any part thereof in an aggregate amount not less than $300,000 or
a higher integral multiple of $100,000) for a new Interest Period;
provided that after giving effect to any prepayment, conversion or
continuation, the aggregate principal amount of each Group of Eurodollar
Loans shall be at least $300,000 and an integral multiple of $100,000.

(b)  The Company shall give written or telephonic (followed immediately
by written confirmation thereof) notice to the Agent of each proposed
conversion or continuation not later than (i) in the case of conversion
into Base Rate Loans, 11:00 A.M., Chicago time, on the proposed date of
such conversion and (ii) in the case of conversion into or continuation
of Eurodollar Loans, 11:00 A.M., Chicago time, at least three Business
Days prior to the proposed date of such conversion or continuation,
specifying in each case: 

(i)  the proposed date of conversion or continuation;

(ii)  the aggregate amount of Loans to be converted or continued;

(iii) the type of Loans resulting from the proposed conversion or
continuation; and

(iv)  in the case of conversion into, or continuation of, Eurodollar
Loans, the duration of the requested Interest Period therefor.

(c)  If upon the expiration of any Interest Period applicable to
Eurodollar Loans, the Company has failed to select timely a new
Interest Period to be applicable to such Eurodollar Loans, the Company
shall be deemed to have elected to convert such Eurodollar Loans into
Base Rate Loans effective on the last day of such Interest Period.

(d)  The Agent will promptly notify each Bank of its receipt of a notice
of conversion or continuation pursuant to this Section 2.2.3 or, if no
timely notice is provided by the Company, of the details of any automatic
conversion.

(e)  Any conversion of a Eurodollar Loan on a day other than the last day
of an Interest Period therefor shall be subject to Section 8.4.

2.3  Letter of Credit Procedures.

2.3.1  L/C Applications.  The Company shall give notice to the Agent
and the Issuing Bank of the proposed issuance of each Letter of Credit on
a Business Day which is at least three Business Days (or such lesser
number of days as the Agent and the Issuing Bank shall agree in any
particular instance in their sole discretion) prior to the proposed date
of issuance of such Letter of Credit.  Each such notice shall be
accompanied by an L/C Application, duly executed by the Company and in
all respects satisfactory to the Agent and the Issuing Bank, together
with such other documentation as the Agent or the Issuing Bank may
request in support thereof, it being understood that each L/C Application
shall specify, among other things, the date on which the proposed Letter
of Credit is to be issued, the expiration date of such Letter of Credit
(which shall not be later than the earlier to occur of (x) one year after
the date of issuance thereof (provided that a Letter of Credit with a
one-year tenor may be automatically renewable annually upon notice to the
Agent so long as, after giving effect to any renewal, the expiration date
of such Letter of Credit shall not extend beyond the date referred to in
clause (y)) and (y) thirty days prior to the scheduled Termination Date)
and whether such Letter of Credit is to be transferable in whole or in
part.  So long as the Issuing Bank has not received written notice that
the conditions precedent set forth in Section 11 with respect to the
issuance of such Letter of Credit have not been satisfied, the Issuing
Bank shall issue such Letter of Credit on the requested issuance date. 
The Issuing Bank shall promptly advise the Agent of the issuance of each
Letter of Credit and of any amendment thereto, extension thereof or event
or circumstance changing the amount available for drawing thereunder.  In
the event of any inconsistency between the terms of any L/C Application
and the terms of this Agreement, the terms of this Agreement shall
control.

2.3.2  Participations in Letters of Credit.  Concurrently with the
issuance of each Letter of Credit, the Issuing Bank shall be deemed to
have sold and transferred to each other Bank, and each other Bank shall
be deemed irrevocably and unconditionally to have purchased and received
from the Issuing Bank, without recourse or warranty, an undivided
interest and participation, to the extent of such other Bank's Pro Rata
Share, in such Letter of Credit and the Company's reimbursement
obligations with respect thereto.  For the purposes of this Agreement,
the unparticipated portion of each Letter of Credit shall be deemed to be
the Issuing Bank's "participation" therein.  The Issuing Bank hereby
agrees, upon request of the Agent or any Bank, to deliver to the Agent or
such Bank a list of all outstanding Letters of Credit issued by the
Issuing Bank, together with such information related thereto as the Agent
or such Bank may reasonably request.

2.3.3  Reimbursement Obligations.  The Company hereby unconditionally and
irrevocably agrees to reimburse the Issuing Bank for each payment or
disbursement made by the Issuing Bank under any Letter of Credit honoring
any demand for payment made by the beneficiary thereunder, in each case
on the date that such payment or disbursement is made.  Any amount not
reimbursed on the date of such payment or disbursement shall bear
interest from the date of such payment or disbursement to the date that
the Issuing Bank is reimbursed by the Company therefor, payable on
demand, at a rate per annum equal to the Base Rate from time to time in
effect plus the Base Rate Margin from time to time in effect plus,
beginning on the third Business Day after receipt of notice from the
Issuing Bank of such payment or disbursement, 2%.  The Issuing Bank shall
notify the Company and the Agent whenever any demand for payment is made
under any Letter of Credit by the beneficiary thereunder; provided that
the failure of the Issuing Bank to so notify the Company shall not affect
the rights of the Issuing Bank or the Banks in any manner whatsoever.

2.3.4  Limitation on Obligations of Issuing Bank.  In determining whether
to pay under any Letter of Credit, the Issuing Bank shall not have any
obligation to the Company or any Bank other than to confirm that any
documents required to be delivered under such Letter of Credit appear
to have been delivered and appear to comply on their face with the
requirements of such Letter of Credit.  Any action taken or omitted to be
taken by the Issuing Bank under or in connection with any Letter of
Credit, if taken or omitted in the absence of gross negligence and
willful misconduct, shall not impose upon the Issuing Bank any liability
to the Company or any Bank and shall not reduce or impair the Company's
reimbursement obligations set forth in Section 2.3.3 or the obligations
of the Banks pursuant to Section 2.3.5.

2.3.5  Funding by Banks to Issuing Bank.  If the Issuing Bank makes any
payment or disbursement under any Letter of Credit and the Company has
not reimbursed the Issuing Bank in full for such payment or disbursement
by 11:00 A.M., Chicago time, on the date of such payment or disbursement,
or if any reimbursement received by the Issuing Bank from the Company is
or must be returned or rescinded upon or during any bankruptcy or
reorganization of the Company or otherwise, each other Bank shall be
obligated to pay to the Agent for the account of the Issuing Bank, in
full or partial payment of the purchase price of its participation in
such Letter of Credit, its Pro Rata Share of such payment or disbursement
(but no such payment shall diminish the obligations of the Company under
Section 2.3.3), and, upon notice from the Issuing Bank, the Agent shall
promptly notify each other Bank thereof.  Each other Bank irrevocably and
unconditionally agrees to so pay to the Agent in immediately available
funds for the Issuing Bank's account the amount of such other Bank's
Percentage of such payment or disbursement.  If and to the extent any
Bank shall not have made such amount available to the Agent by 2:00 P.M.,
Chicago time, on the Business Day on which such Bank receives notice from
the Agent of such payment or disbursement (it being understood that any
such notice received after noon, Chicago time, on any Business Day shall
be deemed to have been received on the next following Business Day), such
Bank agrees to pay interest on such amount to the Agent for the Issuing
Bank's account forthwith on demand, for each day from the date such
amount was to have been delivered to the Agent to the date such amount is
paid, at a rate per annum equal to (a) for the first three days after
demand, the Federal Funds Rate from time to time in effect and (b)
thereafter, the Base Rate from time to time in effect.  Any Bank's
failure to make available to the Agent its Pro Rata Share of any such
payment or disbursement shall not relieve any other Bank of its
obligation hereunder to make available to the Agent such other Bank's Pro
Rata Share of such payment, but no Bank shall be responsible for the
failure of any other Bank to make available to the Agent such other
Bank's Pro Rata Share of any such payment or disbursement.

2.4  Commitments Several.  The failure of any Bank to make a requested
Loan on any date shall not relieve any other Bank of its obligation (if
any) to make a Loan on such date, but no Bank shall be responsible for
the failure of any other Bank to make any Loan to be made by such other
Bank. 

2.5  Certain Conditions.  Notwithstanding any other provision of this
Agreement, no Bank shall have an obligation to make any Loan, or to
permit the continuation of or any conversion into any Eurodollar Loan,
and the Issuing Bank shall not have any obligation to issue any Letter of
Credit, if an Event of Default or Unmatured Event of Default exists.

SECTION 3 NOTES EVIDENCING LOANS.

3.1  Notes.  The Loans of each Bank shall be evidenced by a promissory
note (each a "Note") substantially in the form set forth in Exhibit A,
with appropriate insertions, payable to the order of such Bank in a face
principal amount equal to the sum of such Bank's Pro Rata Share of the
Revolving Commitment Amount plus the principal amount of such Bank's Term
Loan, as follows:

(a)  each Revolving Loan of such Bank shall be paid in full on the
Termination Date; and

(b)  the Term Loan of such Bank shall be paid in installments equal to
such Bank's Pro Rata Share of the aggregate principal amount of the
installments of the Term Loans as set forth on Schedule 3.1.

3.2  Recordkeeping.  Each Bank shall record in its records, or at its
option on the schedule attached to its Note, the date and amount of
each Loan made by such Bank, each repayment or conversion thereof and, in
the case of each Eurodollar Loan, the dates on which each Interest Period
for such Loan shall begin and end.  The aggregate unpaid principal amount
so recorded shall be rebuttable presumptive evidence of the principal
amount owing and unpaid on such Note.  The failure to so record any such
amount or any error in so recording any such amount shall not, however,
limit or otherwise affect the obligations of the Company hereunder or
under any Note to repay the principal amount of the Loans evidenced by
such Note together with all interest accruing thereon.

SECTION 4  INTEREST.

4.1  Interest Rates.  Each of the Companies promises to pay, on a joint
and several basis, interest on the unpaid principal amount of each Loan
for the period commencing on the date of such Loan until such Loan is
paid in full as follows:

annum equal to the sum of the Base Rate from time to time in effect plus
the Base Rate Margin from time to time in effect; and

annum equal to the sum of the Eurodollar Rate (Reserve Adjusted)

Required Banks, the interest rate applicable to each Loan shall be
increased by 2%.

shall be payable in arrears on the last day of each calendar quarter
and at maturity.  Accrued interest on each Eurodollar Loan shall be
payable on the last day of each Interest Period relating to such Loan
(and, in the case of a Eurodollar Loan with a six-month Interest Period,
on the three-month anniversary of the first day of such Interest Period)
and at maturity.  After maturity, accrued interest on all Loans shall be
payable on demand.

4.3  Setting and Notice of Eurodollar Rates.  The applicable Eurodollar
Rate for each Interest Period shall be determined by the Agent, and
notice thereof shall be given by the Agent promptly to the Company and
each Bank.  Each determination of the applicable Eurodollar Rate by the
Agent shall be conclusive and binding upon the parties hereto, in the
absence of demonstrable error.  The Agent shall, upon written request of
the Company or any Bank, deliver to the Company or such Bank a statement
showing the computations used by the Agent in determining any applicable
Eurodollar Rate hereunder.

4.4  Computation of Interest.  Interest shall be computed for the actual

Share (as adjusted from time to time) of the unused amount of the
Revolving Commitment Amount.  For purposes of calculating usage under
this Section, the Revolving Commitment Amount shall be deemed used to the
extent of the aggregate principal amount of all outstanding Revolving
Loans plus the Stated Amount of all Letters of Credit.  Such non-use fee
shall be payable in arrears on the last day of each calendar quarter and
on the Termination Date for any period then ending for which such non-use
fee shall not have previously been paid.  The non-use fee shall be
computed for the actual number of days elapsed on the basis of a year of
360 days.

5.2  Letter of Credit Fees.  (a) Each of the Companies agrees to pay, on
a joint and several basis, to the Agent for the account of each Bank a
letter of credit fee for each Letter of Credit equal to the LC Fee Rate

from time to time) of the undrawn amount of such Letter of Credit
(computed for the actual number of days elapsed on the basis of a year of
360 days); provided that, if requested by the Required Banks, the rate
applicable to each Letter of Credit shall be increased by 2% at any time
that an Event of Default exists.  Such letter of credit fee shall be
payable in arrears on the last day of each calendar quarter and on the
Termination Date (or such later date on which such Letter of Credit
expires or is terminated) for the period from the date of the issuance of
each Letter of Credit (or the last day on which the letter of credit fee
was paid with respect thereto) to the date such payment is due or, if
earlier, the date on which such Letter of Credit expired or was
terminated.

(b)  In addition, with respect to each Letter of Credit, each of the

10.7), in an amount equal to 100% of such Net Cash Proceeds.

(iv) Within 90 days after the end of each Fiscal Year(commencing with
Fiscal Year 1999), in an amount equal to 75% of Excess Cash Flow for such
Fiscal Year, or, if for any Fiscal Year (commencing with Fiscal Year
1999) the Senior Debt to EBITDA Ratio shall be equal to or less than
1.50, 50% of Excess Cash Flow for such Fiscal Year.

(b)  If on any day the Revolving Outstandings exceed the Borrowing Base,
the Company shall immediately prepay Revolving Loans and/or Cash
Collateralize the outstanding Letters of Credit, or do a combination of
the foregoing, in an amount sufficient to eliminate such excess.

6.3  All Prepayments.  Each voluntary partial prepayment shall be in a
principal amount of $50,000 or a higher integral multiple of $50,000. Any
partial prepayment of a Group of Eurodollar Loans shall be subject to the
proviso to Section 2.2.3(a).  Any prepayment of a Eurodollar Loan on a
day other than the last day of an Interest Period therefor shall include
interest on the principal amount being repaid and shall be subject to
Section 8.4.  All prepayments of Term Loans shall be applied pro rata to
the remaining installments thereof.


SECTION 7  MAKING AND PRORATION OF PAYMENTS; SETOFF; TAXES.

7.1  Making of Payments. All payments of principal of or interest on the
Notes, and of all fees, shall be made by the Company to the Agent in
immediately available funds at the office specified by the Agent not
later than noon, Chicago time, on the date due; and funds received after
that hour shall be deemed to have been received by the Agent on the
following Business Day.  The Agent shall promptly remit to each Bank its
share of all such payments received in collected funds by the Agent for
the account of such Bank.  All payments under Section 8.1 shall be made
by the Company directly to the Bank entitled thereto.

7.2  Application of Certain Payments.  Each payment of principal shall be
applied to such Loans as the Company shall direct by notice to be
received by the Agent on or before the date of such payment or, in the
absence of such notice, as the Agent shall determine in its discretion. 
Concurrently with each remittance to any Bank of its share of any such
payment, the Agent shall advise such Bank as to the application of such
payment.

7.3  Due Date Extension.  If any payment of principal or interest with
respect to any of the Loans, or of any fees, falls due on a day which is
not a Business Day, then such due date shall be extended to the
immediately following Business Day (unless, in the case of a Eurodollar
Loan, such immediately following Business Day is the first Business Day
of a calendar month, in which case such due date shall be the immediately
preceding Business Day) and, in the case of principal, additional
interest shall accrue and be payable for the period of any such
extension.

7.4  Setoff.  The Company agrees that the Agent and each Bank have all
rights of set-off and bankers' lien provided by applicable law, and in
addition thereto, the Company agrees that at any time any Event of
Default exists, the Agent and each Bank may apply to the payment of any
obligations of the Company hereunder, whether or not then due, any and
all balances, credits, deposits, accounts or moneys of the Company then
or thereafter with the Agent or such Bank.

7.5  Proration of Payments.  If any Bank shall obtain any payment or
other recovery (whether voluntary, involuntary, by application of offset
or otherwise, but excluding any payment pursuant to Section 8.7 or 14.9
and payments of interest on any Affected Loan) on account of principal of
or interest on any Loan (or on account of its participation in any Letter
of Credit) in excess of its pro rata share of payments and other
recoveries obtained by all Banks on account of principal of and interest
on the Loans (or such participation) then held by them, such Bank shall
purchase from the other Banks such participations in the Loans (or sub-
participations in Letters of Credit) held by them as shall be necessary
to cause such purchasing Bank to share the excess payment or other
recovery ratably with each of them; provided that if all or any portion
of the excess payment or other recovery is thereafter recovered from such
purchasing Bank, the purchase shall be rescinded and the purchase price
restored to the extent of such recovery.

7.6  Taxes.  All payments of principal of, and interest on, the Loans and
all other amounts payable hereunder shall be made free and clear of and
without deduction for any present or future income, excise, stamp or
franchise taxes and other taxes, fees, duties, withholdings or other
charges of any nature whatsoever imposed by any taxing authority,
excluding franchise taxes and taxes imposed on or measured by any Bank's
net income or receipts (all non-excluded items being called "Taxes").  If
any withholding or deduction from any payment to be made by the Company
hereunder is required in respect of any Taxes pursuant to any applicable
law, rule or regulation, then the Company will:

(a)  pay directly to the relevant authority the full amount required to
be so withheld or deducted;

(b)  promptly forward to the Agent an official receipt or other      
documentation satisfactory to the Agent evidencing such payment to such
authority; and 

(c)  pay to the Agent for the account of the Banks such additional amount
or amounts as is necessary to ensure that the net amount actually
received by each Bank will equal the full amount such Bank would have
received had no such withholding or deduction been required.

Moreover, if any Taxes are directly asserted against the Agent or any
Bank with respect to any payment received by the Agent or such Bank
hereunder, the Agent or such Bank may pay such Taxes and the Company will
promptly pay such additional amounts (including any penalty, interest or
expense) as is necessary in order that the net amount received by such
Person after the payment of such Taxes (including any Taxes on such
additional amount) shall equal the amount such Person would have received
had such Taxes not been asserted.

      If the Company fails to pay any Taxes when due to the appropriate
taxing authority or fails to remit to the Agent, for the account of the
respective Banks, the required receipts or other required documentary
evidence, the Company shall indemnify the Banks for any incremental
Taxes, interest or penalties that may become payable by any Bank as a
result of any such failure.  For purposes of this Section 7.6, a
distribution hereunder by the Agent or any Bank to or for the account of
any Bank shall be deemed a payment by the Company.

      Each Bank that (a) is organized under the laws of a jurisdiction
other than the United States of America and (b)(i) is a party hereto on
the Closing Date or (ii) becomes an assignee of an interest under this
Agreement under Section 14.9.1 after the Closing Date (unless such Bank
was already a Bank hereunder immediately prior to such assignment) shall
execute and deliver to the Company and the Agent one or more (as the
Company or the Agent may reasonably request) United States Internal
Revenue Service Forms 4224 or Forms 1001 or such other forms or
documents, appropriately completed, as may be applicable to establish
that such Bank is exempt from withholding or deduction of Taxes.  The
Company shall not be required to pay additional amounts to any Bank
pursuant to this Section 7.6 to the extent that the obligation to pay
such additional amounts would not have arisen but for the failure of such
Bank to comply with this paragraph.

SECTION 8  INCREASED COSTS; SPECIAL PROVISIONS FOR EURODOLLAR LOANS.

      8.1  Increased Costs.  (a)  If, after the date hereof, the adoption
of, or any change in, any applicable law, rule or regulation, or any
change in the interpretation or administration of any applicable law,
rule or regulation by any governmental authority, central bank or
comparable agency charged with the interpretation or administration
thereof, or compliance by any Bank (or any Eurodollar Office of such
Bank) with any request or directive (whether or not having the force of
law) of any such authority, central bank or comparable agency

(i)  shall subject any Bank (or any Eurodollar Office of such Bank) to
any tax, duty or other charge with respect to its Eurodollar Loans, its
Note or its obligation to make Eurodollar Loans, or shall change the
basis of taxation of payments to any Bank of the principal of or interest
on its Eurodollar Loans or any other amounts due under this Agreement in
respect of its Eurodollar Loans or its obligation to make Eurodollar
Loans (except for changes in the rate of tax on the overall net income of
such Bank or its Eurodollar Office imposed by the jurisdiction in which
such Bank's principal executive office or Eurodollar Office is located);

(ii)  shall impose, modify or deem applicable any reserve (including any
reserve imposed by the FRB, but excluding any reserve included in the
determination of interest rates pursuant to Section 4), special deposit
or similar requirement against assets of, deposits with or for the
account of, or credit extended by any Bank(or any Eurodollar Office of
such Bank); or

(iii)  shall impose on any Bank (or its Eurodollar Office) any other
condition affecting its Eurodollar Loans, its Note or its obligation to
make Eurodollar Loans;

and the result of any of the foregoing is to increase the cost to (or to
impose a cost on) such Bank (or any Eurodollar Office of such Bank) of
making or maintaining any Eurodollar Loan, or to reduce the amount of any
sum received or receivable by such Bank (or its Eurodollar Office) under
this Agreement or under its Note with respect thereto, then upon demand
by such Bank (which demand shall be accompanied by a statement setting
forth the basis for such demand and a calculation of the amount thereof
in reasonable detail, a copy of which shall be furnished to the Agent),
the Company shall pay directly to such Bank such additional amount as
will compensate such Bank for such increased cost or such reduction.

(b)  If any Bank shall reasonably determine that any change in, the
adoption or phase-in of, any applicable law, rule or regulation regarding
capital adequacy, or any change in the interpretation or administration
thereof by any governmental authority, central bank or comparable agency
charged with the interpretation or administration thereof, or compliance
by any Bank or any Person controlling such Bank with any request or
directive regarding capital adequacy (whether or not having the force of
law) of any such authority, central bank or comparable agency, has or
would have the effect of reducing the rate of return on such Bank's or
such controlling Person's capital as a consequence of such Bank's
obligations hereunder or under any Letter of Credit to a level below that
which such Bank or such controlling Person could have achieved but for
such change, adoption, phase-in or compliance (taking into consideration
such Bank's or such controlling Person's policies with respect to capital
adequacy) by an amount deemed by such Bank or such controlling Person to
be material, then from time to time, upon demand by such Bank (which
demand shall be accompanied by a statement setting forth the basis for
such demand and a calculation of the amount thereof in reasonable detail,
a copy of which shall be furnished to the Agent), the Company shall pay
to such Bank such additional amount as will compensate such Bank or such
controlling Person for such reduction.

8.2  Basis for Determining Interest Rate Inadequate or Unfair.  If with
respect to any Interest Period:

(a)  deposits in Dollars (in the applicable amounts) are not being
offered to the Agent in the interbank eurodollar market for such Interest
Period, or the Agent otherwise reasonably determines (which determination
shall be binding and conclusive on the Company) that by reason of
circumstances affecting the interbank eurodollar market adequate and
reasonable means do not exist for ascertaining the applicable Eurodollar
Rate; or

(b)  Banks having aggregate Pro Rata Shares of 40% or more advise the
Agent that the Eurodollar Rate (Reserve Adjusted) as determined by the
Agent will not adequately and fairly reflect the cost to such Banks of
maintaining or funding Eurodollar Loans for such Interest Period (taking
into account any amount to which such Banks may be entitled under Section
8.1) or that the making or funding of Eurodollar Loans has become
impracticable as a result of an event occurring after the date of this
Agreement which in the opinion of such Banks materially affects such
Loans;

then the Agent shall promptly notify the other parties thereof and, so
long as such circumstances shall continue, (i) no Bank shall be under any
obligation to make or convert into Eurodollar Loans and (ii) on the last
day of the current Interest Period for each Eurodollar Loan, such Loan
shall, unless then repaid in full, automatically convert to a Base Rate
Loan.

8.3  Changes in Law Rendering Eurodollar Loans Unlawful.  If any change
in, or the adoption of any new, law or regulation, or any change in the
interpretation of any applicable law or regulation by any governmental or
other regulatory body charged with the administration thereof, should
make it (or in the good faith judgment of any Bank cause a substantial
question as to whether it is) unlawful for any Bank to make, maintain or
fund Eurodollar Loans, then such Bank shall promptly notify each of the
other parties hereto and, so long as such circumstances shall continue,
(a) such Bank shall have no obligation to make or convert into Eurodollar
Loans (but shall make Base Rate Loans concurrently with the making of or
conversion into Eurodollar Loans by the Banks which are not so affected,
in each case in an amount equal to the amount of Eurodollar Loans which
would be made or converted into by such Bank at such time in the absence
of such circumstances) and (b) on the last day of the current Interest
Period for each Eurodollar Loan of such Bank (or, in any event,  on such
earlier date as may be required by the relevant law, regulation or
interpretation), such Eurodollar Loan shall, unless then repaid in full,
automatically convert to a Base Rate Loan.  Each Base Rate Loan made by a
Bank which, but for the circumstances described in the foregoing
sentence, would be a Eurodollar Loan (an "Affected Loan") shall remain
outstanding for the same period as the Group of Eurodollar Loans of which
such Affected Loan would be a part absent such circumstances.

8.4  Funding Losses.  The Company hereby agrees that upon demand by any
Bank (which demand shall be accompanied by a statement setting forth
the basis for the amount being claimed, a copy of which shall be
furnished to the Agent), the Company will indemnify such Bank against any
net loss or expense which such Bank may sustain or incur (including any
net loss or expense incurred by reason of the liquidation or reemployment
of deposits or other funds acquired by such Bank to fund or maintain any
Eurodollar Loan), as reasonably determined by such Bank, as a result of
(a) any payment, prepayment or conversion of any Eurodollar Loan of such
Bank on a date other than the last day of an Interest Period for such
Loan (including any conversion pursuant to Section 8.3) or (b) any
failure of the Company to borrow, convert or continue any Loan on a date
specified therefor in a notice of borrowing, conversion or continuation
pursuant to this Agreement.  For this purpose, all notices to the Agent
pursuant to this Agreement shall be deemed to be irrevocable.

8.5  Right of Banks to Fund through Other Offices.  Each Bank may, if it
so elects, fulfill its commitment as to any Eurodollar Loan by causing a
foreign branch or Affiliate of such Bank to make such Loan; provided that
in such event for the purposes of this Agreement such Loan shall be
deemed to have been made by such Bank and the obligation of the Company
to repay such Loan shall nevertheless be to such Bank and shall be deemed
held by it, to the extent of such Loan, for the account of such branch or
Affiliate.

8.6  Discretion of Banks as to Manner of Funding.  Notwithstanding any
provision of this Agreement to the contrary, each Bank shall be entitled
to fund and maintain its funding of all or any part of its Loans in any
manner it sees fit, it being understood, however, that for the purposes
of this Agreement all determinations hereunder shall be made as if such
Bank had actually funded and maintained each Eurodollar Loan during each
Interest Period for such Loan through the purchase of deposits having a
maturity corresponding to such Interest Period and bearing an interest
rate equal to the Eurodollar Rate for such Interest Period.

8.7  Mitigation of Circumstances; Replacement of Banks.  (a) Each Bank
shall promptly notify the Company and the Agent of any event of which it
has knowledge which will result in, and will use reasonable commercial
efforts available to it (and not, in such Bank's sole judgment, otherwise
disadvantageous to such Bank) to mitigate or avoid, (i) any obligation by
the Company to pay any amount pursuant to Section 7.6 or 8.1 or (ii) the
occurrence of any circumstances described in Section 8.2 or 8.3 (and, if
any Bank has given notice of any such event described in clause (i) or
(ii) above and thereafter such event ceases to exist, such Bank shall
promptly so notify the Company and the Agent). Without limiting the
foregoing, each Bank will designate a different funding office if such
designation will avoid (or reduce the cost to the Company of) any event
described in clause (i) or (ii) of the preceding sentence and such
designation will not, in such Bank's sole judgment, be otherwise
disadvantageous to such Bank.

(b)  If the Company becomes obligated to pay additional amounts to any
Bank pursuant to Section 7.6 or 8.1, or any Bank gives notice of the
occurrence of any circumstances described in Section 8.2 or 8.3, the
Company may designate another bank which is acceptable to the Agent and
the Issuing Bank in their reasonable discretion (such other bank being
called a "Replacement Bank") to purchase the Loans of such Bank and such
Bank's rights hereunder, without recourse to or warranty by, or expense
to, such Bank, for a purchase price equal to the outstanding principal
amount of the Loans payable to such Bank plus any accrued but unpaid
interest on such Loans and all accrued but unpaid fees owed to such Bank
and any other amounts payable to such Bank under this Agreement, and to
assume all the obligations of such Bank hereunder, and, upon such
purchase and assumption (pursuant to an Assignment Agreement), such Bank
shall no longer be a party hereto or have any rights hereunder (other
than rights with respect to indemnities and similar rights applicable to
such Bank prior to the date of such purchase and assumption) and shall be
relieved from all obligations to the Company hereunder, and the
Replacement Bank shall succeed to the rights and obligations of such Bank
hereunder. 

8.8  Conclusiveness of Statements; Survival of Provisions. Determinations
and statements of any Bank pursuant to Section 8.1, 8.2, 8.3 or 8.4 shall
be conclusive absent demonstrable error.  Banks may use reasonable
averaging and attribution methods in determining compensation under
Sections 8.1 and 8.4, and the provisions of such Sections shall survive
repayment of the Loans, cancellation of the Notes, expiration or
termination of the Letters of Credit and termination of this Agreement.

SECTION 9  WARRANTIES.

      To induce the Agent and the Banks to enter into this Agreement and
to induce the Banks to make Loans and issue and participate in Letters of
Credit hereunder, each of the Companies warrants, jointly and severally,
to the Agent and the Banks that:

9.1  Organization.  Each of the Companies is a corporation validly
existing and in good standing under the laws of the State of its
incorporation; each Subsidiary is validly existing and in good standing
under the laws of the jurisdiction of its organization; and each of the
Companies and each Subsidiary is duly qualified to do business in each
jurisdiction where, because of the nature of its activities or
properties, such qualification is required, except for such jurisdictions
where the failure to so qualify would not have a Material Adverse Effect. 

9.2  Authorization; No Conflict.  Each of the Companies and each other
Loan Party is duly authorized to execute and deliver each Loan Document
to which it is a party, each of the Companies is duly authorized to
borrow monies hereunder and each of the Companies and each other Loan
Party is duly authorized to perform its obligations under each Loan
Document to which it is a party.  The execution, delivery and performance
by each of the Companies of this Agreement and by each of the Companies
and each other Loan Party of each Loan Document to which it is a party,
and the borrowings by the Companies hereunder, do not and will not (a)
require any consent or approval of any governmental agency or authority
(other than any consent or approval which has been obtained and is in
full force and effect), (b) conflict with (i) any provision of law, (ii)
the charter, by-laws or other organizational documents of the Companies
or any other Loan Party or (iii) any material agreement, indenture,
instrument or other document, or any judgment, order or decree, which is
binding upon any of the Companies or any other Loan Party or any of their
respective properties or (c) require, or result in, the creation or
imposition of any Lien on any asset of any of the Companies, any
Subsidiary or any other Loan Party (other than Liens in favor of the
Agent created pursuant to the Collateral Documents).

9.3  Validity and Binding Nature.  Each of this Agreement and each other
Loan Document to which any of the Companies or any other Loan Party is a
party is the legal, valid and binding obligation of such Person,
enforceable against such Person in accordance with its terms, subject to
bankruptcy, insolvency and similar laws affecting the enforceability of
creditors' rights generally and to general principles of equity.

9.4  Financial Statements and Projections.  (a) Schedule 9.4 contains a
complete and correct copy of the audited consolidated balance sheets of
Compudyne as of December 31, 1995, December 31, 1996 and December 31,

results of operations of Compudyne as of the dates thereof and for the
periods then ended.  Schedule 9.4 also contains unaudited balance sheets
of Norment and Norshield as of February 29, 1996, February 28, 1997 and
February 28, 1998 and unaudited statements of income and cash flow for

periods, and fairly present in all material respects the pro forma
financial condition and pro forma results of operations of the Company
(including Norment and Norshield) as of the date thereof and for the
period then ended, subject to normal year-end adjustments and the absence
of footnotes.  

(c) The financial projections attached as Schedule 9.4(c) (the
"Projections") have been prepared by Compudyne in light of the past
operations of its business and in good faith, subject to the
uncertainties inherent in estimating Compudyne's future performance and
the limited familiarity of Compudyne with respect to Norment and
Norshield.  The Projections are based on assumptions that, as of the
respective dates thereof, were reasonable in light of the information
available to Compudyne on or prior to the date hereof.

9.5  No Material Adverse Change.  Since September 30, 1998 there has
been no material adverse change in the financial condition, operations,
assets, business, properties or prospects of any of the Companies and
their Subsidiaries taken as a whole.

9.6  Litigation and Contingent Liabilities.  No litigation (including
derivative actions), arbitration proceeding or governmental investigation
or proceeding is pending or, to the Companies' knowledge, threatened
against any of the Companies or any Subsidiary which might reasonably be
expected to have a Material Adverse Effect, except as set forth in
Schedule 9.6.  Other than any liability incident to such litigation or
proceedings, none of the Companies or any Subsidiary has any material
contingent liabilities not listed on Schedule 9.6 or permitted by Section
10.7.

9.7  Ownership of Properties; Liens.  Each of the Companies and each
Subsidiary owns good and, in the case of real property, marketable title

charges and claims (including infringement claims with respect to
patents, trademarks, service marks, copyrights and the like) except as
permitted by Section 10.8.

9.8  Subsidiaries.  As of the Closing Date, the Companies have no
Subsidiaries other than those listed on Schedule 9.8.  Neither Compudyne,
Inc. nor Compudyne Corp. of Maryland own, or will own, any assets or
engage, or will engage, in any business during the term hereof.  

9.9  Pension Plans. (a)  During the twelve-consecutive-month period prior
to the date of the execution and delivery of this Agreement or the making
of any Loan or the issuance of any Letter of Credit, (i) no steps have
been taken to terminate any Pension Plan and (ii) no contribution failure
has occurred with respect to any Pension Plan sufficient to give rise to
a Lien under Section 302(f) of ERISA.  No condition exists or event or
transaction has occurred with respect to any Pension Plan which could
result in the incurrence by any of the Companies of any material
liability, fine or penalty. 

(b)  All contributions (if any) have been made to any Multiemployer
Pension Plan that are required to be made by any of the Companies or any
other member of the Controlled Group under the terms of the plan or of
any collective bargaining agreement or by applicable law; none of the

partially withdrawn from any Multiemployer Pension Plan, incurred any
withdrawal liability with respect to any such plan or received notice of
any claim or demand for withdrawal liability or partial withdrawal
liability from any such plan, and no condition has occurred which, if
continued, might result in a withdrawal or partial withdrawal from any
such plan; and none of the Companies or any member of the Controlled
Group has received any notice that any Multiemployer Pension Plan is in
reorganization, that increased contributions may be required to avoid a
reduction in plan benefits or the imposition of any excise tax, that any
such plan is or has been funded at a rate less than that required under
Section 412 of the Code, that any such plan is or may be terminated, or
that any such plan is or may become insolvent.

9.10  Investment Company Act.  None of the Companies or any Subsidiary is
an "investment company" or a company "controlled" by an "investment
company", within the meaning of the Investment Company Act of 1940.

9.11  Public Utility Holding Company Act.  None of the Companies or any
Subsidiary is a "holding company", or a "subsidiary company" of a
"holding company", or an "affiliate" of a "holding company" or of a

9.13  Taxes.  Each of the Companies and each Subsidiary has filed all tax
returns and reports required by law to have been filed by it and has paid
all taxes and governmental charges thereby shown to be owing, except any
such taxes or charges which are being diligently contested in good faith
by appropriate proceedings and for which adequate reserves in accordance
with GAAP shall have been set aside on its books.

9.14  Solvency, etc.  On the Closing Date, and immediately prior to and
after giving effect to the issuance of each Letter of Credit and each
borrowing hereunder, the issuance of subordinated debt pursuant to the
Subordinated Debt Documents and the use of the proceeds thereof to fund
the Purchase and for other purposes permitted hereunder, (a) each of the
Companies' and each other Loan Party's assets will exceed its liabilities
and (b) each of the Companies and each other Loan Party will be solvent,
will be able to pay its debts as they mature, will own property with fair
saleable value greater than the amount required to pay its debts and will
have capital sufficient to carry on its business as then constituted.

9.15  Environmental Matters.

(a)  No Violations. Except as set forth on Schedule 9.15, none of the
Companies or any Subsidiary, or, to the best knowledge of the Company,
any operator of the Companies' or any Subsidiary's properties, is in
violation, or alleged violation, of any judgment, decree, order, law,
permit, license, rule or regulation pertaining to environmental matters,
including those arising under the Resource Conservation and Recovery Act
("RCRA"), the Comprehensive Environmental Response, Compensation and
Liability Act of 1980 ("CERCLA"), the Superfund Amendments and
Reauthorization Act of 1986 or any other Environmental Law which (i) in
any single case, requires expenditures in any three-year period of
$100,000 or more by such Company and its Subsidiaries in penalties and/or
for investigative, removal or remedial actions or (ii) individually or in
the aggregate otherwise might reasonably be expected to have a Material
Adverse Effect.

(b)  Notices.  Except as set forth on Schedule 9.15 and for matters
arising after the Closing Date, in each case none of which could singly
or in the aggregate be expected to have a Material Adverse Effect, none
of the Companies or any Subsidiary has received notice from any third
party, including any Federal, state or local governmental authority:  (a)
that any one of them has been identified by the U.S. Environmental
Protection Agency as a potentially responsible party under CERCLA with
respect to a site listed on the National Priorities List, 40 C.F.R. Part
300 Appendix B; (b) that any hazardous waste, as defined by 42 U.S.C.
Section 6903(5), any hazardous substance as defined by 42 U.S.C. Section
601(14), any pollutant or contaminant as defined by 42 U.S.C. Section
9601(33) or any toxic substance, oil or hazardous material or other
chemical or substance regulated by any Environmental Law (all of the
foregoing, "Hazardous Substances") which any one of them has generated,
transported or disposed of has been found at any site at which a Federal,
state or local agency or other third party has conducted a remedial
investigation, removal or other response action pursuant to any
Environmental Law; (c) that any of the Companies or any Subsidiary must

Claim.

(c)  Handling of Hazardous Substances.  Except as set forth on Schedule
9.15, (i) no portion of the real property or other assets of the
Companies or any Subsidiary has been used for the handling, processing,
storage or disposal of Hazardous Substances except in accordance in all
material respects with applicable Environmental Laws; and no underground
tank or other underground storage receptacle for Hazardous Substances is
located on such properties; (ii) in the course of any activities
conducted by the Companies, any Subsidiary or, to the best knowledge of
the Company, the operators of any real property of the Companies or any
Subsidiary, no Hazardous Substances have been generated or are being used
on such properties except in accordance in all material respects with
applicable Environmental Laws; (iii) there have been no Releases or
threatened Releases of Hazardous Substances on, upon, into or from any
real property or other assets of any of the Companies or any Subsidiary,
which Releases singly or in the aggregate might reasonably be expected to
have a material adverse effect on the value of such real property or
assets; (iv) there have been no Releases on, upon, from or into any real
property in the vicinity of the real property or other assets of the
Companies or any Subsidiary which, through soil or groundwater
contamination, may have come to be located on, and which might reasonably
be expected to have a material adverse effect on the value of, the real
property or other assets of any of the Companies or any Subsidiary; and
(v) to the best knowledge of the Company, any Hazardous Substances

12.1.13 Material Adverse Effect. The occurrence of any event having a
Material Adverse Effect.

12.2  Effect of Event of Default. If any Event of Default described in
Section 12.1.4 shall occur, the Commitments (if they have not theretofore
terminated) shall immediately terminate and the Loans and all other
obligations hereunder shall become immediately due and payable and the
Company shall become immediately obligated to Cash Collateralize all
Letters of Credit, all without presentment, demand, protest or notice of
any kind; and, if any other Event of Default shall occur and be
continuing, the Agent (upon written request of the Required Banks) shall
declare the Commitments (if they have not theretofore terminated) to be
terminated and/or declare all Loans and all other obligations hereunder
to be due and payable and/or demand that the Company immediately Cash
Collateralize all Letters of Credit, whereupon the Commitments (if they
have not theretofore terminated) shall immediately terminate and/or all
Loans and all other obligations hereunder shall become immediately due
and payable and/or the Company shall immediately become obligated to Cash
Collateralize all Letters of Credit, all without presentment, demand,
protest or notice of any kind.  The Agent shall promptly advise the
Company of any such declaration, but failure to do so shall not impair
the effect of such declaration.  Notwithstanding the foregoing, the
effect as an Event of Default of any event described in Section 12.1.1 or
Section 12.1.4 may be waived by the written concurrence of all of the
Banks, and the effect as an Event of Default of any other event described
in this Section 12 may be waived by the written concurrence of the
Required Banks.  Any cash collateral delivered hereunder shall be held by
the Agent (without liability for interest thereon) and applied to
obligations arising in connection with any drawing under a Letter of
Credit.  After the expiration or termination of all Letters of Credit,
such cash collateral shall be applied by the Agent to any remaining
obligations hereunder and any excess shall be delivered to the Company or
as a court of competent jurisdiction may elect.

SECTION 13  THE AGENT.

13.1  Appointment and Authorization. (a) Each Bank hereby irrevocably
(subject to Section 13.9) appoints, designates and authorizes the Agent
to take such action on its behalf under the provisions of this Agreement
and each other Loan Document and to exercise such powers and perform such
duties as are expressly delegated to it by the terms of this Agreement or
any other Loan Document, together with such powers as are reasonably
incidental thereto.  Notwithstanding any provision to the contrary
contained elsewhere in this Agreement or in any other Loan Document, the
Agent shall not have any duty or responsibility except those expressly
set forth herein, nor shall the Agent have or be deemed to have any
fiduciary relationship with any Bank, and no implied covenants,
functions, responsibilities, duties, obligations or liabilities shall be
read into this Agreement or any other Loan Document or otherwise exist
against the Agent.

(b)  The Issuing Bank shall act on behalf of the Banks with respect to
any Letters of Credit issued by it and the documents associated
therewith.  The Issuing Bank shall have all of the benefits and
immunities (i) provided to the Agent in this Section 13 with respect to
any acts taken or omissions suffered by the Issuing Bank in connection
with Letters of Credit issued by it or proposed to be issued by it and
the applications and agreements for letters of credit pertaining to such
Letters of Credit as fully as if the term "Agent", as used in this
Section 13, included the Issuing Bank with respect to such acts or
omissions and (ii) as additionally provided in this Agreement with
respect to the Issuing Bank.

13.2  Delegation of Duties. The Agent may execute any of its duties under
this Agreement or any other Loan Document by or through agents, employees
or attorneys-in-fact and shall be entitled to advice of counsel
concerning all matters pertaining to such duties.  The Agent shall not be
responsible for the negligence or misconduct of any agent or
attorney-in-fact that it selects with reasonable care.

13.3  Liability of Agent.  None of the Agent nor any of its directors,
officers, employees or agents shall (i) be liable for any action taken or
omitted to be taken by any of them under or in connection with this
Agreement or any other Loan Document or the transactions contemplated
hereby (except for its own gross negligence or willful misconduct), or
(ii) be responsible in any manner to any of the Banks for any recital,
statement, representation or warranty made by the Company or any
Subsidiary or Affiliate of the Company, or any officer thereof, contained
in this Agreement or in any other Loan Document, or in any certificate,
report, statement or other document referred to or provided for in, or
received by the Agent under or in connection with, this Agreement or any
other Loan Document, or the validity, effectiveness, genuineness,
enforceability or sufficiency of this Agreement or any other Loan
Document, or for any failure of the Company or any other party to any
Loan Document to perform its obligations hereunder or thereunder. The
Agent shall not be under any obligation to any Bank to ascertain or to
inquire as to the observance or performance of any of the agreements
contained in, or conditions of, this Agreement or any other Loan
Document, or to inspect the properties, books or records of the Company
or any of the Company's Subsidiaries or Affiliates.

13.4  Reliance by Agent.  The Agent shall be entitled to rely, and shall
be fully protected in relying, upon any writing, resolution, notice,
consent, certificate, affidavit, letter, telegram, facsimile, telex or
telephone message, statement or other document or conversation believed
by it to be genuine and correct and to have been signed, sent or made by
the proper Person or Persons, and upon advice and statements of legal
counsel (including counsel to the Company), independent accountants and
other experts selected by the Agent.  The Agent shall be fully justified
in failing or refusing to take any action under this Agreement or any
other Loan Document unless it shall first receive such advice or
concurrence of the Required Banks as it deems appropriate and, if it so
requests, confirmation from the Banks of their obligation to indemnify
the Agent against any and all liability and expense which may be incurred
by it by reason of taking or continuing to take any such action.  The
Agent shall in all cases be fully protected in acting, or in refraining
from acting, under this Agreement or any other Loan Document in
accordance with a request or consent of the Required Banks and such
request and any action taken or failure to act pursuant thereto shall be
binding upon all of the Banks.

13.5  Notice of Default.  The Agent shall not be deemed to have knowledge
or notice of the occurrence of any Event of Default or Unmatured Event of
Default except with respect to defaults in the payment of principal,
interest and fees required to be paid to the Agent for the account of the
Banks, unless the Agent shall have received written notice from a Bank or
the Company referring to this Agreement, describing such Event of Default
or Unmatured Event of Default and stating that such notice is a "notice
of default".  The Agent will notify the Banks of its receipt of any such
notice.  The Agent shall take such action with respect to such Event of
Default or Unmatured Event of Default as may be requested by the Required
Banks in accordance with Section 12; provided that unless and until the
Agent has received any such request, the Agent may (but shall not be
obligated to) take such action, or refrain from taking such action, with
respect to such Event of Default or Unmatured Event of Default as it
shall deem advisable or in the best interest of the Banks.

13.6  Credit Decision.  Each Bank acknowledges that the Agent has not
made any representation or warranty to it, and that no act by the Agent
hereafter taken, including any review of the affairs of the Company and
its Subsidiaries, shall be deemed to constitute any representation or
warranty by the Agent to any Bank.  Each Bank represents to the Agent
that it has, independently and without reliance upon the Agent and based
on such documents and information as it has deemed appropriate, made its
own appraisal of and investigation into the business, prospects,
operations, property, financial and other condition and creditworthiness
of the Company and its Subsidiaries, and made its own decision to enter
into this Agreement and to extend credit to the Company hereunder.  Each
Bank also represents that it will, independently and without reliance
upon the Agent and based on such documents and information as it shall
deem appropriate at the time, continue to make its own credit analysis,
appraisals and decisions in taking or not taking action under this
Agreement and the other Loan Documents, and to make such investigations
as it deems necessary to inform itself as to the business, prospects,
operations, property, financial and other condition and creditworthiness
of the Company.  Except for notices, reports and other documents
expressly herein required to be furnished to the Banks by the Agent, the
Agent shall not have any duty or responsibility to provide any Bank with
any credit or other information concerning the business, prospects,
operations, property, financial or other condition or creditworthiness of
the Company which may come into the possession of the Agent.

13.7  Indemnification.  Whether or not the transactions contemplated
hereby are consummated, the Banks shall indemnify upon demand the Agent
and its directors, officers, employees and agents (to the extent not
reimbursed by or on behalf of the Company and without limiting the
obligation of the Company to do so), pro rata, from and against any and
all Indemnified Liabilities; provided that no Bank shall be liable for
any payment to any such Person of any portion of the Indemnified
Liabilities resulting from such Person's gross negligence or willful
misconduct.  Without limitation of the foregoing, each Bank shall
reimburse the Agent upon demand for its ratable share of any costs or
out-of-pocket expenses (including Attorney Costs) incurred by the Agent
in connection with the preparation, execution, delivery, administration,
modification, amendment or enforcement (whether through negotiations,
legal proceedings or otherwise) of, or legal advice in respect of rights
or responsibilities under, this Agreement, any other Loan Document, or
any document contemplated by or referred to herein, to the extent that
the Agent is not reimbursed for such expenses by or on behalf of the
Company.  The undertaking in this Section shall survive repayment of the
Loans, cancellation of the Notes, expiration or termination of the
Letters of Credit, any foreclosure under, or modification, release or
discharge of, any or all of the Collateral Documents, termination of this
Agreement and the resignation or replacement of the Agent.

13.8  Agent in Individual Capacity.  LaSalle and its Affiliates may make
loans to, issue letters of credit for the account of, accept deposits
from, acquire equity interests in and generally engage in any kind of
banking, trust, financial advisory, underwriting or other business with
the Company and its Subsidiaries and Affiliates as though LaSalle were
not the Agent or the Issuing Bank hereunder and without notice to or
consent of the Banks.  The Banks acknowledge that, pursuant to such
activities, LaSalle or its Affiliates may receive information regarding
the Company or its Affiliates (including information that may be subject
to confidentiality obligations in favor of the Company or such Affiliate)
and acknowledge that the Agent shall be under no obligation to provide
such information to them.  With respect to their Loans (if any), LaSalle
and its Affiliates shall have the same rights and powers under this
Agreement as any other Bank and may exercise the same as though LaSalle
were not the Agent and the Issuing Bank, and the terms "Bank" and "Banks"
include LaSalle and its Affiliates, to the extent applicable, in their
individual capacities.

13.9  Successor Agent.  The Agent may resign as Agent upon 30 days'
notice to the Banks.  If the Agent resigns under this Agreement, the
Required Banks shall, with (so long as no Event of Default exists) the
consent of the Company (which shall not be unreasonably withheld or
delayed), appoint from among the Banks a successor agent for the Banks. 
If no successor agent is appointed prior to the effective date of the
resignation of the Agent, the Agent may appoint, after consulting with
the Banks and the Company, a successor agent from among the Banks.  Upon
the acceptance of its appointment as successor agent hereunder, such
successor agent shall succeed to all the rights, powers and duties of the
retiring Agent and the term "Agent" shall mean such successor agent, and
the retiring Agent's appointment, powers and duties as Agent shall be
terminated. After any retiring Agent's resignation hereunder as Agent,
the provisions of this Section 13 and Sections 14.6 and 14.13 shall inure
to its benefit as to any actions taken or omitted to be taken by it while
it was Agent under this Agreement.  If no successor agent has accepted
appointment as Agent by the date which is 30 days following a retiring
Agent's notice of resignation, the retiring Agent's resignation shall
nevertheless thereupon become effective and the Banks shall perform all
of the duties of the Agent hereunder until such time, if any, as the
Required Banks appoint a successor agent as provided for above.

13.10  Collateral Matters.  The Banks irrevocably authorize the Agent, at
its option and in its discretion, (a) to release any Lien granted to or
held by the Agent under any Collateral Document (i) upon termination of
the Commitments and payment in full of all Loans and all other
obligations of the Company hereunder and the expiration or termination of
all Letters of Credit; (ii) constituting property sold or to be sold or
disposed of as part of or in connection with any disposition permitted
hereunder; or (iii) subject to Section 14.1, if approved, authorized or
ratified in writing by the Required Banks; or (b) to subordinate its
interest in any collateral to any holder of a Lien on such collateral
which is permitted by clause (d)(i) or (d)(iii) of Section 10.8 (it being
understood that the Agent may conclusively rely on a certificate from the
Company in determining whether the Debt secured by any such Lien is
permitted by Section 10.7(b)).  Upon request by the Agent at any time,
the Banks will confirm in writing the Agent's authority to release, or
subordinate its interest in, particular types or items of collateral
pursuant to this Section 13.10.

SECTION 14  GENERAL.

14.1  Waiver; Amendments.  No delay on the part of the Agent or any Bank
in the exercise of any right, power or remedy shall operate as a waiver
thereof, nor shall any single or partial exercise by any of them of any
right, power or remedy preclude other or further exercise thereof, or the
exercise of any other right, power or remedy.  No amendment, modification
or waiver of, or consent with respect to, any provision of this Agreement
or the Notes shall in any event be effective unless the same shall be in
writing and signed and delivered by Banks having an aggregate Pro Rata
Share of not less than the aggregate Pro Rata Share expressly designated
herein with respect thereto or, in the absence of such designation as to
any provision of this Agreement or the Notes, by the Required Banks, and
then any such amendment, modification, waiver or consent shall be
effective only in the specific instance and for the specific purpose for
which given.  No amendment, modification, waiver or consent shall change
the Pro Rata Share of any Bank without the consent of such Bank.  No
amendment, modification, waiver or consent shall (i) increase the
Revolving Commitment Amount, (ii) extend the date for payment of any
principal of or interest on the Loans or any fees payable hereunder,
(iii) reduce the principal amount of any Loan, the rate of interest
thereon or any fees payable hereunder, (iv) release the Guaranty or all
or any substantial part of the collateral granted under the Collateral
Documents or (v) reduce the aggregate Pro Rata Share required to effect
an amendment, modification, waiver or consent without, in each case, the
consent of all Banks.  No provision of Section 13 or other provision of
this Agreement affecting the Agent in its capacity as such shall be
amended, modified or waived without the consent of the Agent.  No
provision of this Agreement relating to the rights or duties of the
Issuing Bank in its capacity as such shall be amended, modified or waived
without the consent of the Issuing Bank.

14.2  Confirmations.  The Company and each holder of a Note agree from
time to time, upon written request received by it from the other, to
confirm to the other in writing (with a copy of each such confirmation to
the Agent) the aggregate unpaid principal amount of the Loans then
outstanding under such Note.

14.3  Notices.  Except as otherwise provided in Sections 2.2.2 and 2.2.3,
all notices hereunder shall be in writing (including facsimile
transmission) and shall be sent to the applicable party at its address
shown on Schedule 14.3 or at such other address as such party may, by
written notice received by the other parties, have designated as its
address for such purpose.  Notices sent by facsimile transmission shall
be deemed to have been given when sent; notices sent by mail shall be
deemed to have been given three Business Days after the date when sent by
registered or certified mail, postage prepaid; and notices sent by hand
delivery or overnight courier service shall be deemed to have been given
when received.  For purposes of Sections 2.2.2 and 2.2.3, the Agent shall
be entitled to rely on telephonic instructions from any person that the
Agent in good faith believes is an authorized officer or employee of the
Company, and the Company shall hold the Agent and each other Bank
harmless from any loss, cost or expense resulting from any such reliance.

14.4  Computations.  Where the character or amount of any asset or
liability or item of income or expense is required to be determined, or
any consolidation or other accounting computation is required to be made,
for the purpose of this Agreement, such determination or calculation
shall, to the extent applicable and except as otherwise specified in this
Agreement, be made in accordance with GAAP, consistently applied;
provided that if the Company notifies the Agent that the Company wishes
to amend any covenant in Section 10 to eliminate or to take into account
the effect of any change in GAAP on the operation of such covenant (or if
the Agent notifies the Company that the Required Banks wish to amend
Section 10 for such purpose), then the Company's compliance with such
covenant shall be determined on the basis of GAAP in effect immediately
before the relevant change in GAAP became effective, until either such
notice is withdrawn or such covenant is amended in a manner satisfactory
to the Company and the Required Banks.

14.5  Regulation U.  Each Bank represents that it in good faith is not
relying, either directly or indirectly, upon any Margin Stock as
collateral security for the extension or maintenance by it of any credit
provided for in this Agreement.

14.6  Costs, Expenses and Taxes.  The Company agrees to pay on demand all
reasonable out-of-pocket costs and expenses of the Agent (including
Attorney Costs) in connection with the preparation, execution,
syndication, delivery and administration of this Agreement, the other
Loan Documents and all other documents provided for herein or delivered
or to be delivered hereunder or in connection herewith (including any
amendment, supplement or waiver to any Loan Document), and all reasonable
out-of-pocket costs and expenses (including Attorney Costs) incurred by
the Agent and each Bank after an Event of Default in connection with the
enforcement of this Agreement, the other Loan Documents or any such other
documents.  In addition, the Company agrees to pay, and to save the Agent
and the Banks harmless from all liability for, (a) any stamp or other
taxes (excluding income taxes and franchise taxes based on net income)
which may be payable in connection with the execution and delivery of
this Agreement, the borrowings hereunder, the issuance of the Notes or
the execution and delivery of any other Loan Document or any other
document provided for herein or delivered or to be delivered hereunder or
in connection herewith and (b) any fees of the Company's auditors in
connection with any reasonable exercise by the Agent and the Banks of
their rights pursuant to Section 10.2.  All obligations provided for in
this Section 14.6 shall survive repayment of the Loans, cancellation of
the Notes, expiration or termination of the Letters of Credit and
termination of this Agreement.

14.7  Subsidiary References.  The provisions of this Agreement relating
to Subsidiaries shall apply only during such times as the Company has one
or more Subsidiaries.

14.8  Captions.  Section captions used in this Agreement are for
convenience only and shall not affect the construction of this Agreement.

14.9  Assignments; Participations. 

14.9.1  Assignments.  Any Bank may, with the prior written consents of
the Issuing Bank and the Agent and (so long as no Event of Default
exists) the Company (which consents shall not be unreasonably delayed or
withheld and, in any event, shall not be required for an assignment by a
Bank to one of its Affiliates), at any time assign and delegate to one or
more commercial banks or other Persons (any Person to whom such an
assignment and delegation is to be made being herein called an
"Assignee") all or any fraction of such Bank's Loans and Commitment
(which assignment and delegation shall be of a constant, and not a
varying, percentage of all the assigning Bank's Loans and Commitment) in
a minimum aggregate amount equal to the lesser of (i) the amount of the
assigning Bank's Pro Rata Share of the Revolving Commitment Amount plus
the unpaid amount of such Bank's Term Loan and (ii) $5,000,000; provided
that (a) no assignment and delegation may be made to any Person if, at
the time of such assignment and delegation, the Company would be
obligated to pay any greater amount under Section 7.6 or Section 8 to the
Assignee than the Company is then obligated to pay to the assigning Bank
under such Sections (and if any assignment is made in violation of the
foregoing, the Company will not be required to pay the incremental
amounts) and (b) the Company and the Agent shall be entitled to continue
to deal solely and directly with such Bank in connection with the
interests so assigned and delegated to an Assignee until the date when
all of the following conditions shall have been met:

(x)  five Business Days (or such lesser period of time as the Agent and
the assigning Bank shall agree) shall have passed after written notice of
such assignment and delegation, together with payment instructions,
addresses and related information with respect  to such Assignee, shall
have been given to the Company and the Agent by such assigning Bank and
the Assignee,

(y)  the assigning Bank and the Assignee shall have executed and
delivered to the Company and the Agent an assignment agreement in form
and substance satifactory to the Agent (an "Assignment Agreement"),
together with any documents required to be delivered thereunder, which
Assignment Agreement shall have been accepted by the Agent, and

(z) except in the case of an assignment by a Bank to one of its
Affiliates, the assigning Bank or the Assignee shall have paid the Agent
a processing fee of $3,500. 

From and after the date on which the conditions described above have been
met, (x) such Assignee shall be deemed automatically to have become a
party hereto and, to the extent that rights and obligations hereunder
have been assigned and delegated to such Assignee pursuant to such
Assignment Agreement, shall have the rights and obligations of a Bank
hereunder and (y) the assigning Bank, to the extent that rights and
obligations hereunder have been assigned and delegated by it pursuant to
such Assignment Agreement, shall be released from its obligations
hereunder.  Within five Business Days after effectiveness of any
assignment and delegation, the Company shall execute and deliver to the
Agent (for delivery to the Assignee and the Assignor, as applicable) a
new Note in the principal amount of the Assignee's Pro Rata Share of the
Revolving Commitment Amount plus the principal amount of the Assignee's
Term Loan and, if the assigning Bank has retained a Commitment hereunder,
a replacement Note in the principal amount of the Pro Rata Share of the
Revolving Commitment Amount retained by the assigning Bank plus the
principal amount of the Term Loan retained by the assigning Bank (such
Note to be in exchange for, but not in payment of, the predecessor Note
held by such assigning Bank).  Each such Note shall be dated the
effective date of such assignment.  The assigning Bank shall mark the
predecessor Note "exchanged" and deliver it to the Company.  Accrued
interest on that part of the predecessor Note being assigned shall be
paid as provided in the Assignment Agreement.  Accrued interest and fees
on that part of the predecessor Note not being assigned shall be paid to
the assigning Bank.  Accrued interest and accrued fees shall be paid at
the same time or times provided in the predecessor Note and in this
Agreement.  Any attempted assignment and delegation not made in
accordance with this Section 14.9.1 shall be null and void.

Notwithstanding the foregoing provisions of this Section 14.9.1 or any
other provision of this Agreement, any Bank may at any time assign all or
any portion of its Loans and its Note to a Federal Reserve Bank (but no
such assignment shall release any Bank from any of its obligations
hereunder).

14.9.2  Participations.  Any Bank may at any time sell to one or more
commercial banks or other Persons participating interests in any Loan
owing to such Bank, the Note held by such Bank, the Commitment of such
Bank, the direct or participation interest of such Bank in any Letter of
Credit or any other interest of such Bank hereunder (any Person
purchasing any such participating interest being herein called a
"Participant").  In the event of a sale by a Bank of a participating
interest to a Participant, (x) such Bank shall remain the holder of its
Note for all purposes of this Agreement, (y) the Company and the Agent
shall continue to deal solely and directly with such Bank in connection
with such Bank's rights and obligations hereunder and (z) all amounts
payable by the Company shall be determined as if such Bank had not sold
such participation and shall be paid directly to such Bank.  No
Participant shall have any direct or indirect voting rights hereunder
except with respect to any of the events described in the fourth sentence
of Section 14.1.  Each Bank agrees to incorporate the requirements of the
preceding sentence into each participation agreement which such Bank
enters into with any Participant.  The Company agrees that if amounts
outstanding under this Agreement and the Notes are due and payable (as a
result of acceleration or otherwise), each Participant shall be deemed to
have the right of setoff in respect of its participating interest in
amounts owing under this Agreement, any Note and with respect to any
Letter of Credit to the same extent as if the amount of its participating
interest were owing directly to it as a Bank under this Agreement or such
Note; provided that such right of setoff shall be subject to the
obligation of each Participant to share with the Banks, and the Banks
agree to share with each Participant, as provided in Section 7.5.  The
Company also agrees that each Participant shall be entitled to the
benefits of Section 7.6 and Section 8 as if it were a Bank (provided that
no Participant shall receive any greater compensation pursuant to Section
7.6 or Section 8 than would have been paid to the participating Bank if
no participation had been sold).

14.10  Governing Law.  This Agreement and each Note shall be a contract
made under and governed by the internal laws of the State of Illinois
applicable to contracts made and to be performed entirely within such
State.  Whenever possible each provision of this Agreement shall be
interpreted in such manner as to be effective and valid under applicable
law, but if any provision of this Agreement shall be prohibited by or
invalid under applicable law, such provision shall be ineffective to the
extent of such prohibition or invalidity, without invalidating the
remainder of such provision or the remaining provisions of this
Agreement.  All obligations of the Company and rights of the Agent and
the Banks expressed herein or in any other Loan Document shall be in
addition to and not in limitation of those provided by applicable law.

14.11  Counterparts.  This Agreement may be executed in any number of
counterparts and by the different parties hereto on separate counterparts
and each such counterpart shall be deemed to be an original, but all such
counterparts shall together constitute but one and the same Agreement.

14.12  Successors and Assigns.  This Agreement shall be binding upon
the Company, the Banks and the Agent and their respective successors and
assigns, and shall inure to the benefit of the Company, the Banks and the
Agent and the successors and assigns of the Banks and the Agent.

14.13  Indemnification by the Company.  In consideration of the execution
and delivery of this Agreement by the Agent and the Banks and the
agreement to extend the Commitments provided hereunder, the Company
hereby agrees to indemnify, exonerate and hold the Agent, each Bank and
each of the officers, directors, employees, Affiliates and agents of the
Agent and each Bank (each a "Bank Party") free and harmless from and
against any and all actions, causes of action, suits, losses,
liabilities, damages and expenses, including Attorney Costs
(collectively, the "Indemnified Liabilities"), incurred by the Bank
Parties or any of them as a result of, or arising out of, or relating to
(i) any tender offer, merger, purchase of stock, purchase of assets
(including the Purchase) or other similar transaction financed or
proposed to be financed in whole or in part, directly or indirectly, with
the proceeds of any of the Loans, (ii) the use, handling, release,
emission, discharge, transportation, storage, treatment or disposal of
any hazardous substance at any property owned or leased by the Company or
any Subsidiary, (iii) any violation of any Environmental Laws with
respect to conditions at any property owned or leased by the Company or
any Subsidiary or the operations conducted thereon, (iv) the
investigation, cleanup or remediation of offsite locations at which the
Company or any Subsidiary or their respective predecessors are alleged to
have directly or indirectly disposed of hazardous substances or (v) the
execution, delivery, performance or enforcement of this Agreement or any
other Loan Document by any of the Bank Parties, except for any such
Indemnified Liabilities arising on account of the applicable Bank Party's
gross negligence or willful misconduct.  If and to the extent that the
foregoing undertaking may be unenforceable for any reason, the Company
hereby agrees to make the maximum contribution to the payment and
satisfaction of each of the Indemnified Liabilities which is permissible
under applicable law.  All obligations provided for in this Section 14.13
shall survive repayment of the Loans, cancellation of the Notes,
expiration or termination of the Letters of Credit, any foreclosure
under, or any modification, release or discharge of, any or all of the
Collateral Documents and termination of this Agreement.

14.14  Nonliability of Lenders.  The relationship between the Company on
the one hand and the Banks and the Agent on the other hand shall be
solely that of borrower and lender.  Neither the Agent nor any Bank shall
have any fiduciary responsibility to the Company.  Neither the Agent nor
any Bank undertakes any responsibility to the Company to review or inform
the Company or any matter in connection with any phase of the Company's
business or operations.  The Company agrees that neither the Agent nor
any Bank shall have liability to the Company (whether sounding in tort,
contract or otherwise) for losses suffered by the Company in connection
with, arising out of, or in any way related to the transactions
contemplated and the relationship established by the Loan Documents, or
any act, omission or event occurring in connection therewith, unless it
is determined in a final non-appealable judgment by a court of competent
jurisdiction that such losses resulted from the gross negligence or
willful misconduct of the party from which recovery is sought.  Neither
the Agent nor any Bank shall have any liability with respect to, and the
Company hereby waives, releases and agrees not to sue for, any special,
indirect or consequential damages suffered by the Company in connection
with, arising out of, or in any way related to the Loan Documents or the
transactions contemplated thereby. 

14.15  Forum Selection and Consent to Jurisdiction.  ANY LITIGATION
BASED HEREON, OR ARISING OUT OF, UNDER, OR IN CONNECTION WITH THIS
AGREEMENT OR ANY OTHER LOAN DOCUMENT, SHALL BE BROUGHT AND MAINTAINED
EXCLUSIVELY IN THE COURTS OF THE STATE OF ILLINOIS OR IN THE UNITED

THAT ANY SUIT SEEKING ENFORCEMENT AGAINST ANY COLLATERAL OR OTHER

              SUBORDINATED LOAN AND INVESTMENT AGREEMENT
                                    


     THIS SUBORDINATED LOAN AND INVESTMENT AGREEMENT (the
"Agreement") is made and entered into as of November 30, 1998 by
and between COMPUDYNE CORPORATION, a Nevada corporation (the
"Company"), and WILLIAM BLAIR MEZZANINE CAPITAL FUND II, L.P., an
Illinois limited partnership (the "Lender").

                                RECITALS

A.   The Company desires to obtain a senior subordinated loan
from the Lender and the Lender is willing to make such senior
subordinated loan on the terms and conditions provided below.

B.   The Company desires to issue and sell, and the Lender is
willing to purchase, common stock and a warrant to purchase
additional common stock on the terms and conditions provided
below.

                               AGREEMENTS

     In consideration of the recitals and the mutual agreements
which follow, the parties agree:

1.   Purchase and Sale of the Note, Common Stock and Warrant.  

(a)  Subject to the terms, covenants and conditions of this
Agreement, on the Closing Date (as defined in section 3), the
Company will issue and sell, and the Lender shall buy a
$9,000,000 Senior Subordinated Note (the "Note") evidencing a
term loan in the principal amount of $9,000,000 (the "Loan"). 
The Note shall be dated as of the Closing Date, shall be subject
to the terms and conditions of this Agreement, and shall be in
the form of Appendix 1.  The consideration to be paid by the
Lender for the Note is $9,000,000 and shall be paid by the Lender
at Closing, by wire transfer of same day funds to the Company's
account, upon receipt by the Lender of the Note, duly executed
and in proper form.  The Company and the Lender agree that the
value of the Note at Closing is $9,000,000, and all tax and other
reporting by either of them shall reflect such initial value.

(b)  Subject to the terms, covenants and conditions of this
Agreement, on the Closing Date the Company will issue and sell,
and the Lender shall buy, the below-described securities
(sometimes collectively referred to as the "Equity Securities"),
consisting in the aggregate of 1,075,507 shares (the "Shares") of
the Company's Common Stock (the "Common Stock") and a warrant
("Warrant") to purchase an additional 297,924 shares of the
Company's Common Stock for an initial exercise price of $3.25 per
share.  

     The consideration to be paid by the Lender at the Closing
for the Equity Securities issued to and purchased by it at the
Closing is: (a) for the Shares an aggregate of $2,999,000; and
(b) for the Warrant an aggregate further consideration of $1,000. 
The consideration to be paid by the Lender for the Equity
Securities, in the aggregate amount of $3,000,000, will be paid
at the Closing, by wire transfer of same day funds to the
Company's account, upon receipt by the Lender of a certificate or
certificates for the Shares and the Warrant, in each case duly
executed and in proper form.

2.   Credit Terms.

2.1  Repayment of Principal. Subject to sections 2.3 and 7.3
hereof, the Company shall repay the principal balance of the Loan
in consecutive quarterly installments of $500,000 each on March
31, 2004, June 30, 2004, September 30, 2004, December 31, 2004,
March 31, 2005, June 30, 2005, September 30, 2005, and a final
payment of all unpaid principal on December 31, 2005.

2.2  Interest.  So long as no Event of Default (as defined in
section 7.1) has occurred, the Loan shall bear interest from the
Closing Date until the Loan is paid in full at a fixed annual
rate of 13.15%, computed on the basis of a 360-day year and the
actual number of days elapsed in the period during which interest
accrues.

(a)  Periodic Interest Payments. Accrued interest on the Loan
shall be due and payable quarterly in arrears on the last day of
December, March, June and September (each, a "Quarterly Payment
Date") beginning on December 31, 1998.  In addition, all accrued
and unpaid interest shall be paid upon the payment in full of the
entire outstanding principal amount of the Loan and, if payment
in full is not paid when due, thereafter on demand.
  
(b)  Default Interest Rate.  After the occurrence of any Event of
Default specified in section 7.1 of this Agreement, the
outstanding principal amount of the Loan, all accrued interest
and all other amounts, fees and obligations payable hereunder and
under the Note shall bear interest at the fixed rate of 15.15%
per annum, computed on the basis of a 360-day year and the actual
number of days elapsed in the period during which interest
accrues, and such interest shall be payable on demand, subject to
the final sentence of Section 7.3.


(c)  Saving Clause.  Notwithstanding any other provision
contained in this Agreement, the aggregate annual interest rate
charged with respect to the Loan (including all charges and fees
deemed to be interest pursuant to applicable law) shall not
exceed the maximum annual rate permitted by applicable law.  In
the event that the aggregate annual interest rate payable with
respect to the Loan (including all charges and fees deemed to be
interest under applicable laws) exceeds the maximum legal rate,
the Company shall only pay the Lender interest at the maximum
permitted rate, and the Company shall continue to make such
interest payments at the maximum permitted rate until all
amounts, fees and obligations payable hereunder and under the
Note have been paid in full.

2.3  Prepayments.  Except as provided in section 7 and section
2.3(a), the Loan may not be prepaid, in whole or in part, prior
to December 31, 2001.  Thereafter, the Loan may be prepaid as
provided in section 2.3(b).

(a)  Prepayments From Proceeds of Lender-Approved Transaction. 
"Lender-Approved Transaction" shall mean any of the following
transactions if the Lender has approved such transaction in
writing prior to its consummation:  (i) a sale, transfer or other
disposition of all or substantially all of the assets of the
Company; (ii) a merger of the Company with or into any other
person, or any transaction or series of related transactions,
that results in a change of ownership of 50% or more of the
voting power or equity of the Company.  If, at any time, the
Company consummates a Lender-Approved Transaction, the Company
may, at its option, prepay the Loan, in whole but not in part. 
In the event of any prepayment of the Loan in connection with a
Lender-Approved Transaction, the Company shall pay all accrued
interest and all other fees, expenses and amounts payable by
the Company to the Lender, plus the Prepayment Fee (as defined
below).  If the Lender notifies the Company, within 30 days after
the consummation of the Lender-Approved Transaction, that the
Lender desires the Loan to be repaid, the Company shall, within
five days after such notification, prepay the Loan in full,
including all accrued interest and all other fees, expenses and

the unaudited pro forma consolidated balance sheet of the Company

the other parties thereto (subject only to bankruptcy,
reorganization, insolvency or other similar laws or any
applicable rules of equity).  All such contracts are in full
force and effect and have been approved by all third parties
whose approval is required.  The consummation of the transactions
contemplated hereby (including, but not limited to the

passage of time or the giving of notice or both would constitute
a default under or breach of any of such contracts by the Company
or, to the Company's knowledge, by any other party thereto.

4.13 Compliance with Laws, Instruments, Etc.  

(a)  Generally.  The Company is not in violation of its
Articles of Incorporation or By-Laws, as amended, or in violation
in any material respect of any applicable law, statute or
regulation of any federal, state, municipal or other governmental
or quasi-governmental agency, board, bureau or body relating to

respects with all applicable federal, state, local and foreign
laws, statutes, rules, regulations, ordinances and other
requirements, including, without limitation, permits issued

and contractual obligations concerning public health and safety,
worker health and environmental contamination of any type
whatsoever, including, without limitation, all such standards of
conduct and obligations relating to the presence, use,
production, generation, handling, transport, treatment, storage,

discharge, release, threatened release, control or cleanup of any
hazardous, toxic or otherwise dangerous chemical, material,
substance or waste, or mixture, pesticide, petroleum product or
byproduct, asbestos, polychlorinated biphenyls, noise or
radiation.  Except as disclosed in the Environmental Reports,
there are no claims, demands, and/or governmental or third party
investigations, pending or, to the Company's knowledge,
threatened, relating to any hazardous materials (collectively
called "Environmental Claims") against the Company or relating to
any real property currently or formerly owned or leased by the
Company, or operated by the Company.  Except as disclosed in the
Environmental Reports, there are no lawsuits, judgments, consent
decrees, administrative orders and/or administrative proceedings
(collectively called "Environmental Litigation") pending, or to
the Company's knowledge, threatened against the Company or any
real property presently or formerly owned by the Company,
relating to any hazardous materials treated, stored, used and/or
disposed of by the Company.  Except as disclosed in the
Environmental Reports, to the Company's knowledge, no other
person has caused, discharged, permitted or arranged for any
hazardous material to be used, generated, reclaimed, transported,
released, treated, stored, recycled, refined or disposed of in a
manner which is likely to form the basis for an Environmental
Claim or Environmental Litigation against the Company.  Except as
disclosed on Schedule 4.13, in connection with the Acquisition,
Apogee has assumed liability for all loss, damages, costs or
expenses that may arise with respect to the properties or
operations of Norment and Norshield relating to the period prior
to the Closing Date.  The Company has not assumed any liability

required capital expenditures in connection with any
Environmental Claim or Environmental Litigation.  Except as
described in the Environmental Reports: (i) there are no
underground storage tanks or surface impoundments that are or
were located, on real property currently owned or leased by the
Company or on adjacent parcels of real property; and (ii) no part
of such currently owned, leased and operated real property, and
no part of parcels adjacent to such real property, including the
groundwater located thereon, is presently contaminated by
hazardous materials in violation of any applicable environmental
law.

4.14 Securities Laws.  The sale and delivery of the Note and
the Equity Securities issued to the Lender are (assuming the
accuracy of the Lender's representations in section 8), exempt
from the requirement of registration under the Securities Act of
1933, as amended ("Securities Act") and applicable state "Blue
Sky" laws.

4.15 Brokers.  The Company has not incurred any liability for
any finders' fees, brokerage fees or similar fees or expenses in
connection with entering into this transaction with the Lender
except as fully described on Schedule 4.15.

4.16 Taxes.  The Company has timely filed, or obtained valid
extensions of time for filing (which extensions have not
expired), all federal, state, local and other tax returns and
reports required to be filed by the Company.  All such tax
returns are true and correct in all material respects.  No claim
has been made by any taxing authority in any jurisdiction where
the Company did not file tax returns that the Company is or may
be subject to taxation by that jurisdiction.  Except as disclosed
on Schedule 4.16, in connection with the Acquisition, Apogee has
assumed liability for all loss, damages, costs or expenses that
may arise with respect to the properties or operations of Norment
and Norshield relating to the period prior to the Closing
Date.  Except as disclosed in Schedule 4.16:

(a)  The Company has paid all taxes (including all deficiency
assessments, additions to taxes, penalties and interest, of which
notice has been received) to the extent that such amounts have
become due or are claimed to be due from any federal, state,
local or foreign taxing authorities.

(b)  Adequate provisions have been made in the balance sheet of
the Company as of December 31, 1997 and in the Balance Sheet for
the payment of all then accrued and unpaid federal, state, local
and other taxes, whether or not then due and payable and whether
or not disputed.

(c)  There are no tax liens (other than liens for taxes which are
not yet due and payable) on any property of the Company.

(d)  There are no pending or, to the Company's knowledge,
threatened tax return examinations against the Company.

(e)  There are no tax deficiencies asserted by any jurisdiction
against the Company.

(f)  The Company has not granted any extensions of limitation
periods applicable to tax claims that are currently open.

4.17 Insurance.  Schedule 4.17 contains a correct schedule of
all policies of insurance carried by the Company (including all
policies of which the Company is a beneficiary, is the owner or
pays the premiums with respect thereto) showing material facts as
to coverage.  The insurance it carries is reasonably adequate in
kind and amount to cover insurable risks normally insured against
by companies similarly situated, is subject to the deductibles
and self-insurance  programs disclosed on Schedule 4.17, and all
premiums thereon have been paid as and when due.  All such
policies are in full force and effect.  No notice of cancellation
or termination has been received with respect to any such policy. 
Such policies are valid, outstanding and enforceable policies and
will not in any way be affected by, or terminate or lapse by
reason of, the transactions contemplated by this Agreement.  The
liability insurance coverage to which the Company was a party
throughout the five years preceding the Closing was comparable
(considering inflation during such period) to the coverage
currently in effect and was adequate considering the nature of
its businesses.  During such five year period the Company
suffered no material insurable loss for which a claim was not
made.  The Company has not been refused any insurance with
respect to any material assets or operations, nor has its
coverage been limited in any respect material to its operations,
by any insurance carrier to which it has applied for any such
insurance or with which it has carried insurance during the last
five years.  The bonding facility described in section 3.13 is
adequate in scope and amount for the Company's current and
projected business.

4.18 Products Liability and Product Warranty.  Schedule 4.18
sets forth all cash expenses, non-cash charges and reserve
activity with respect to the Company's products liability
lawsuits, claims and settlements during the past five years. 
Schedule 4.18 sets forth all cash expenses and non-cash charges
related to warranties of the Company in connection with the sale
of products by the Company during the past three years.  All 
products sold by the Company are in all material respects
manufactured in conformity with all applicable contractual
commitments and all express or implied warranties.  Except as
disclosed on Schedule 4.18, in connection with the Acquisition,
Apogee has assumed liability for all loss, damages, costs or
expenses that may arise with respect to the properties or
operations of Norment and Norshield relating to the period prior
to the Closing Date.

purposes hereof, "control" shall mean the direction of management
or policies (whether through ownership of securities, by contract
or otherwise), provided that any person which owns directly or
indirectly 5% or more of the securities of any other person
having ordinary voting power for the election of directors shall

is the recipient of income from any source other than the Company

organization other than the Company requiring such person to
assign any interest in any invention or trade secrets or to keep
confidential any trade secrets or other proprietary information
or containing any prohibition or restriction on competition or

transaction for which the property remaining with the Company is
an unreasonably small capital.  After giving effect to the

saleable value, in the aggregate, is greater than the amount
required to pay all its indebtedness.

so long as the Company is indebted to the Lender (with respect to

materially relating to the conduct of its business and
maintenance and operation of its respective properties (except

Event of Default is continuing, the Lender, at its option and
without presentment, demand, protest or notice of any kind (all
of which the Company hereby expressly waives), may declare the
Note to be due and payable in full, and it shall thereupon become
immediately due and payable.  From the date of any Event of
Default specified in section 7.1(a), (f), (g),  (i) or (j), and
from the date of Lender's written notice thereof to the Company
after any other Event of Default, all unpaid principal of the
Note held by the Lender shall bear interest at the rate specified
in section 2.2(b) until the Note is paid in full.  

7.4  Expenses.  The Company agrees to pay to the Lender all
reasonable costs and expenses incurred by the Lender (including
reasonable attorneys' fees) in connection with the collection of
the Note or the enforcement or amendment of any provisions of
this Agreement.

7.5  Remedies Cumulative.  The remedies provided in this section
7 are in addition to, and not in limitation of, any other rights
and rmedies the Lender may have upon an Event of Default.  The
Lender may exercise any or all of the remedies provided by this
section 7.

8.   Representations and Warranties of Lender.  The Lender
represents and warrants to the Company that the statements
contained in this section 8 are true, accurate and complete with
respect to the Lender.

8.1  Capacity.  The Lender has such knowledge and experience
in financial and business matters as to be capable of evaluating
the merits and risks of and to protect its own interest in
connection with the acquisition of the Note and the Equity
Securities.

8.2  Accredited Lender.  The Lender is an "accredited investor"
as defined in Regulation D promulgated under the Securities Act.

8.3  Investment Purpose.  The Lender is making this investment
for its own account and not for the account of others and not
with a view to the distribution of the Note or the Equity
Securities, and has no present intention of reselling or dividing
the Note or the Equity Securities, it being understood that
neither the Note nor the Equity Securities (subject to the
Lender's rights under the Registration Agreement) will be
registered under the Securities Act and that the Note and the
Equity Securities will have a legend affixed thereto describing
the restrictions on transferability.

8.4  Disclosure.  The Lender has received copies of the annual
reports on Form 10-K, annual reports to shareholders, quarterly
reports on Form 10-Q, current reports on Form 8-K, and proxy
statements filed by the Company with the Securities and Exchange
Commission during the past three years in compliance with the
rules under the Securities Exchange Act of 1934, as amended.  In
addition, the Lender has had the opportunity to ask questions and
receive written answers concerning the Company and the
Acquisition.

9.   Transfer of Note; Transfer of Equity Securities;
Participation.

9.1  Successor and Assigns in General.  This Agreement shall
be binding upon and, subject to section 9.2 hereof, inure to the
benefit of the parties hereto and their respective successors and
assigns, except that the Company may not assign or transfer its
rights hereunder or any interest herein or delegate its duties
hereunder without the prior written consent of the Lender.  The
Lender shall give the Company prompt written notice of any
assignment of or participation in the Loan hereunder.  Except in
connection with an assignment of its entire interest in the Note
and the Equity Securities, the Lender will continue to act as the
sole agent for purposes of this Agreement on behalf of all
holders of or participants in the Note and/or Equity Securities. 
The Company shall maintain a book-entry system (which shall
include, without limitation, a record of ownership that
identifies each owner of an interest in the Loan or the Note) for
registration as to the rights to principal and stated interest on
the Loan and the Note, and shall promptly register any such
assignment of or participation in the Loan or the Note upon
receipt of such notice.

9.2  Conditions.  The Lender or any Assignee may assign all or
any portion of its interest in and rights under this Agreement,
the Note and the Equity Securities to another person (an
"Assignee"), or grant a participating or beneficial interest in
this Agreement and the Loan to another person (a "Participant"),
subject to the following conditions:

(a)  Securities Laws.  Such assignment or participation shall not
be made under such circumstances as may constitute a violation of
federal securities laws or any applicable state securities laws
or regulations or (unless the transaction has been registered
under the Securities Act) render the Lender an underwriter, as
defined in the Securities Act.  Any proposed assignee or
participant shall be required, as a condition to such assignment
or participation, to provide the Company with written
representations and warranties substantially in the form
contained in section 8.

(b)  Payments; Set Off.  Any payments to or recoveries by the
Lender or any Assignee or Participant under this Agreement or
under any instrument or agreement delivered in connection
herewith shall be for the account of the Lender, and all
Assignees and Participants, in proportion to the amount of each
such person's interest in the Loan.  Rights of setoff and
banker's lien (if any) may be exercised by each such person only
after ten days' prior notice to the Company, and amounts and
property so set off or covered by such Lien may be applied to all
or any of the obligations incurred by the Company under this
Agreement, and all other amounts payable by the Company under
this Agreement which may be due or unpaid as determined by the
Lender, Assignees or Participants to the end that the property
and credit balances of the Company with each such person shall be
security for, and may be applied to the payment of, all or any of
the obligation incurred by the Company under this Agreement, and
such other amounts as though such rights were exercised, and such
amounts were recovered, by the Lender.

(c)  Registration.  The Company shall have registered any such
assignment or grant of a participating or beneficial interest in
the book-entry system maintained by the Company pursuant to
section 9.1 hereof.

(d)  Further Assurance.  The Company shall, from time to time at
the request of the Lender, execute and deliver to the Lender or
to such party or parties as the Lender may designate, any and all
further instruments as may in the reasonable opinion of the
Lender be necessary or advisable to give full force and effect to
any transfer contemplated by this section 9.

10.  Additional Provisions.

10.1 Expenses.  The Company agrees upon demand to pay or
reimburse the Lender for all of its reasonable out-of-pocket
expenses, including, without limitation, all travel, legal,
consulting, accounting and independent analyst fees and expenses,
from time to time (a) arising in connection with (i) the
preparation and execution of this Agreement and all other
documents, agreements, certificates and instruments to be
delivered thereunder and (ii) the legal and financial
investigation and review of the Company, (b) relating to any
amendments, waivers or consents pursuant to the provisions hereof
or thereof, (c) arising in connection with the enforcement of
this Agreement and all other agreements to be delivered hereunder
or collection of the Note, and (d) relating to the attendance of
the Lender's representatives at meetings of the Company's Board
of Directors and the Lender's exercise of its inspection and
visitation rights under section 5.7.  The Company agrees to
pay and save the Lender harmless from all liability for any stamp
or other similar taxes which may be payable in connection with
this Agreement and the other Loan or Equity Securities documents
or the performance of any transactions contemplated hereby or
thereby.

10.2 Survival of Representations and Warranties.  All
representations and warranties contained herein or made by or on
behalf of the Company in writing in connection with the

the Closing and shall survive the consummation of the
transactions contemplated hereby for so long as the Lender (or
its Assignees) hold the Note or Equity Securities issued pursuant
to this Agreement.

for herein or made hereunder shall be delivered, or mailed first

exercise of any other right, power or privilege.  The rights and
remedies provided in this Agreement are cumulative and are in
addition to all rights or remedies which the Lender and such
other holders otherwise may have in law or in equity or by

writing and signed by the Lender and the Company.

10.6 Divisibility and Replacement of Note and Equity Securities. 
Any instrument representing the Loan or any of the Equity
Securities may be divided into multiple notes or certificates in
such denominations as the Lender may request upon surrender of
such instrument at the principal office of the Company.  In case
any instrument evidencing the Loan or any of the Equity
Securities issued to the Lender hereunder shall be mutilated,
lost, stolen, or destroyed, the Company shall issue and deliver

mutilated instrument or in lieu of and substitution for the
instrument lost, stolen or destroyed, a new note or other
document of like tenor and representing an equivalent right or
interest, but only upon receipt of evidence satisfactory to
the Company of such loss, theft or destruction; the affidavit of
the holder, without bond but with promise of indemnity, shall be
satisfactory.  

10.7 Integration.  This Agreement, the appendices and exhibits
annexed hereto and documents, schedules and certificates referred
to herein contain the entire agreement between the Company and
the Lender with respect to the transactions contemplated herein;
and none of the parties shall be bound by nor shall be deemed to
have made any representations and/or warranties except those
contained herein and therein.

10.8 Separability.  If any provision of this Agreement is held
for any reason to be unenforceable by a court of competent
jurisdiction, the remainder of this Agreement shall,
nevertheless, remain in full force and effect in such
jurisdiction.

10.9 Headings.  The headings in this Agreement are intended
solely for convenience of reference and shall be given no effect
in the construction or interpretation of this Agreement.

(a)  General.  In addition to all of the Company's other
obligations under this Agreement, the Company agrees to defend,
protect, indemnify and hold harmless the Lender, its Assignees
and Participants, and all of their respective officers,
directors, shareholders, partners, employees, consultants and
agents (including, without limitation, those retained in
connection with the satisfaction or attempted satisfaction of any
of the conditions set forth in this Agreement) (collectively, the
"Indemnitees") from and against any and all losses, damages,
liabilities, obligations, penalties, fees, costs and expenses
(including, without limitation, reasonable attorneys' and
paralegals' fees, costs and expenses) incurred by such 
Indemnitees, whether prior to or from and after the date of this
Agreement, whether direct, indirect or consequential, as a result
of or arising from or relating to any suit, investigation, action
or proceeding by any person, either threatened or initiated,
asserting a claim for any legal or equitable remedy against any
person under any statute or regulation (other than suits or other
actions by the Company against an Indemnitee where the Company is
successful on the merits), regardless of whether the Indemnitee
seeking indemnification is a party to the action or proceeding
for which indemnification is sought, including, without
limitation, any federal or state securities or labor laws,
or under any environmental and safety requirements or common law
principles arising from or in connection with any of the
following: (A) the negotiation, preparation, execution or
performance of the documents, agreements, certificates or
instruments executed or delivered in connection with the Loan
or the Equity Securities, (B) the Lender's furnishing of funds to
the Company under this Agreement or under the Note or the Equity
Securities or (C) any matter relating to the financing
transactions contemplated by this Agreement or by any document,
agreement, certificate or instrument executed or delivered in
connection with the transactions contemplated hereby (including,
without limitation, any transaction financed or to be financed in
whole or in part, directly or indirectly, with the proceeds of
the Loan or the Equity Securities) (collectively, "Indemnified
Matters").  The Company's indemnification obligation under this
section 10.11(a) shall be reduced by the amount of any insurance
proceeds actually received by the Indemnitee, or any cash benefit
actually received by Indemnitee through the exercise by
Indemnitee of any set-off rights or from the Indemnitee's
assertion of any counterclaim in connection with such suit,
investigation, action or proceeding.  In no event shall the
Lender be liable to the Company or any of its affiliates for
indirect, special, consequential or punitive damages.  To the
extent that this undertaking to indemnify, pay and hold harmless
set forth in this section may be unenforceable for any reason,
the Company shall contribute the maximum portion which it is
permitted to pay and satisfy under applicable law, to the payment
and satisfaction of all Indemnified Matters incurred by
Indemnitees.

(b)  Environmental Liabilities.  Without limiting the generality
of the indemnity set forth in section 10.11(a) hereof, the
Company hereby further indemnifies and agrees to hold harmless
the Lender and all Indemnitees from and against any and all
losses, liabilities, damages, obligations, penalties, injuries,
costs, fees (including, without limitation, attorneys',
paralegals' and expert witnesses' fees, costs and expenses)
expenses and claims of any and every kind whatsoever paid,
incurred or suffered by, or asserted against, the Lender or any
Indemnitee for, with respect to, or as a direct or indirect
result of, the past, present or future activities or operations
of, or the past, present or future condition of any property
owned, operated or otherwise used by the Company, its
predecessors or successors, or any off-site hazardous substance
or waste treatment, storage or disposal facility associated
therewith (the "Properties"), including, without limitation, the
presence on or under, or the escape, seepage, leakage, spillage,
discharge, emission, release, or threatened release into, onto or
from the Properties of any toxic, hazardous or otherwise
dangerous chemical, substance, material or waste, including,
without limitation, any losses, liabilities, damages, injuries,
costs, expenses or claims asserted or arising under any
environmental and safety requirement (including, without
limitation, the Comprehensive Environmental Response,
Compensation and Liability Act), regardless of whether caused by,
or within the control of, the Company.  

(c)  Survival.  All obligations provided for in this section
10.11 shall survive the repayment of the Note and the termination
of this Agreement.
