            NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                 (UNAUDITED)

1.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     The accompanying interim condensed consolidated financial statements have
been prepared by management in accordance with the accounting policies described
in the Company's annual report for the year ended September 30, 1997.  The
condensed consolidated financial statements include the accounts of the Company
and its subsidiaries.  (See Note 3 regarding recent acquisitions).  All
significant intercompany balances and transactions have been eliminated in
consolidation.  The condensed consolidated financial statements have not been
audited by independent auditors.  Certain information and note disclosures
normally included in consolidated financial statements prepared in accordance
with generally accepted accounting principles have been omitted.  These
condensed consolidated financial statements should be read in conjunction with
the audited consolidated financial statements and related notes included in the
Company's Annual Report on Form 10-K for the year ended September 30, 1997.

     The condensed consolidated financial statements reflect all adjustments
which are, in the opinion of management, necessary to present fairly the
financial position of Analytical Surveys, Inc., at June 30, 1998 and its results
of operations for the three and nine months ended June 30, 1998 and 1997, and
its cash flows for the nine months ended June 30, 1998 and 1997.  All such
adjustments are of a normal recurring nature.

     The Company has adopted Statement of Financial Accounting Standards No. 128
"Earnings Per Share" ("SFAS 128").  SFAS 128 requires the restatement of all
prior-period earnings per share ("EPS") data.  SFAS 128 replaces the
presentation of primary EPS, with a presentation of basic EPS and diluted EPS. 
Under SFAS 128, basic EPS excludes dilution for common stock equivalents and is
computed by dividing income available to common shareholders by the weighted
average number of common shares outstanding for the period.  Diluted EPS
reflects the potential dilution that could occur if securities or other
contracts to issue common stock were exercised or converted into common stock or
resulted in the issuance of common stock that then shared in the earnings of the
Company.  The Company's diluted EPS for prior periods is the same as the primary
EPS previously reported while the Company's basic EPS will be greater than the
primary EPS previously reported.


2.   NOTES PAYABLE TO BANK

     On June 3, 1998, the Company replaced its existing lines of credit with a
three-year $11,000,000 secured line of credit and a $10,000,000 line of credit
for acquisitions (which is due in quarterly installments over a five-year
period), and the Company refinanced $16,000,000 of term debt.  Borrowings under
the new credit facilities bear interest at either LIBOR plus 1.25% to 2.25% or
the prime rate.

OVERVIEW
     
     ASI, a leading provider of data conversion and digital mapping services to
users of customized geographic information systems, was founded in 1981 by its
current Chief Technical Officer, John A. Thorpe. From 1981 to 1990, the Company
experienced steady growth in revenues with periodic fluctuations in financial
results. After the hiring of the Company's current Chief Executive Officer and
Chief Financial Officer in 1990, the Company implemented a controlled growth
strategy, including improving and standardizing operating controls and
procedures, investing in infrastructure, upgrading the Company's proprietary
software and establishing capital sources. 

     In 1995, the Company embarked on a more aggressive growth strategy,
including consolidation of the fragmented GIS services industry. The Company
acquired substantially all of the assets of Wisconsin-based Intelligraphics,
Inc. ("Intelligraphics") in December 1995 for $3.5 million in cash and 345,000
shares of restricted Common Stock valued at $891,000. Intelligraphics, with over
200 employees, significantly expanded the Company's capacity to perform large
projects, added utility industry expertise, and established ASI's presence in
the midwestern United States. The acquisition contributed over 25 new customers
and $12.3 million in "backlog," which represents the amount of revenue that has
not been recognized on signed contracts. 

     In July 1996, the Company expanded its services to state and local
governments by acquiring substantially all of the assets of Westinghouse
Landmark GIS, Inc. ("ASI Landmark") for $2.0 million in cash. Based in North

                                JUNE 30, 1998


Carolina, ASI Landmark's primary business is land base and cadastral mapping.
Prior to this acquisition, ASI had utilized subcontractors for certain of these
services. ASI Landmark also provided the Company with additional capacity for
photogrammetry, and a presence in the eastern and southeastern United States.
The acquisition contributed approximately 20 new customers, $9.1 million in
backlog and 105 employees to the Company. 

     The Company acquired MSE Corporation ("MSE") in July 1997 for $12.5 million
in cash and 925,000 shares of restricted Common Stock valued at $7.3 million.
The acquisition of Indiana-based MSE gave the Company greater capacity to serve
the utility market and further enhanced ASI's presence in the midwestern United
States. In addition, the acquisition of MSE contributed over 200 customers and
$43.0 million of backlog to the Company. Over 325 employees joined the ASI
workforce as a result of the MSE acquisition, including the Company's current
Chief Operations Officer and Chief Administrative Officer. 

     The Company acquired Texas-based Cartotech, Inc. ("Cartotech") in June 1998
for approximately $7.7 million in cash, net of cash acquired, and 354,167 shares
of restricted Common Stock valued at approximately $8.3 million, plus
acquisition costs of $359,000. The Cartotech acquisition extended ASI's presence
in the utility market, enhanced the Company's field inventory operations and
provided the Company with a strong presence in the southwestern United States.
The Cartotech acquisition contributed over 50 new customers and 270 employees to
the Company. One of Cartotech's customers, FirstEnergy Corp. (formerly known as
Ohio Edison), accounted for approximately 46.0% of Cartotech's revenues in
calendar 1997. 

     In conjunction with the above acquisitions, the Company has recorded
goodwill, which represents the excess of the purchase price over the fair value
of the net assets acquired in business combinations. As of June 30, 1998,
goodwill, net of accumulated amortization, was $25.5 million. The Company will
amortize the value of the intangible assets acquired in its recent business
acquisitions over a period of 15 years, representing the expected period of
benefit from the acquisitions. The Company believes this amortization period to
be appropriate based on the historical and forecasted operating results of the
acquired businesses. 

     The Company recognizes revenue using the percentage of completion method of
accounting on a cost-to-cost basis. For each contract, an estimate of total
production costs is determined. At each accounting period and for each of the
Company's contracts, the percentage of completion is based on production costs
incurred to date as a percentage of total estimated production costs. This
percentage is then multiplied by the contract's total value to calculate the
sales revenue to be recognized. 

     Production costs consist of internal costs, primarily salaries and wages,
and external costs, primarily subcontractor costs. Internal and external
production costs may vary considerably among projects and during the course of
completion of each project. As a result, the Company experiences yearly and
quarterly fluctuations in production costs, in salaries, wages and related
benefits and in subcontractor costs. These costs may vary as a percentage of
sales from period to period. Since 1995 the Company has relied less on
subcontractors and more on employees. The Company anticipates that, as a
percentage of sales, salaries, wages and related benefits will continue to
increase, with a corresponding decrease in subcontractor costs, due, in part, to
the Company's May 1998 purchase of Interra Technologies, an India-based company
that had been a provider of subcontractor services to the Company. The following
table illustrates the relationship of salaries, wages and related benefits and
subcontractor costs:

     The Company recognizes losses on contracts in the period such loss is
determined. From the beginning of fiscal 1995 through the nine-month period
ending June 30, 1998, the Company has recognized aggregate losses on contracts
of approximately $913,000. Over the same period, the Company recognized sales of
$137.2 million. Sales and marketing expenses associated with obtaining contracts
are expensed as incurred. 

     Backlog increases when new contracts are signed and decreases as revenue is
recognized. As of June 30, 1998, backlog was $113.6 million. Recently, the
number of large projects awarded to the Company has increased. Contracts for
larger projects generally increase the Company's risk due to inflation as well
as changes in customer expectations and funding availability. The Company's
contracts are generally terminable on short notice, and while in the Company's
experience such termination is rare, there is no assurance that the Company will
receive all of the revenue anticipated under signed contracts. 
     
     The Company engages in significant research and development activities. The
majority of these activities occur as the Company develops software or designs a
product for a particular contract, so that the costs of such efforts are
included as an integral part of the Company's services. Such custom-designed
software can often be applied to projects for other customers. These amounts
expended by the Company are not included in research and development expenses,
although the Company retains ownership of such proprietary software or products.
The Company, through its Advanced Technology Division, also engages in research
and development activities independently of the Company's work on particular
customer projects. For fiscal 1997 and for the nine months ended June 30, 1998,
the Company expended $275,000 and $190,000, respectively, on such independent
research and development activities.

                        QUARTERLY REPORT ON FORM 10-Q
                                JUNE 30, 1998


THREE MONTHS ENDED JUNE 30, 1998 AND 1997

     SALES.  The Company's sales consist of revenue recognized for services
performed. Sales increased $14.3 million or 168.2% to $22.8 million for the
three months ended June 30, 1998 from $8.5 million for the three months ended
June 30, 1997. This increase was due to an increase in the number and size of
customer contracts with the Company (including MSE) as well as the impact of the
acquisition of MSE in July 1997. Prior to its acquisition by the Company, MSE's
sales for the three months ended June 30, 1997 were $6.9 million. 

     SALARIES, WAGES AND RELATED BENEFITS.  Salaries, wages and related 
benefits include employee compensation for production, marketing, selling, 
administrative and executive employees. Salaries, wages and related benefits 
increased 165.0% to $10.6 million for the three months ended June 30, 1998 
from $4.0 million for the three months ended June 30, 1997. This increase was 
primarily due to the addition of over 325 employees as a result of the MSE 
acquisition in July 1997, as well as the hiring of additional employees to 
support the Company's increased business. As a percentage of sales, salaries, 
wages and related benefits decreased to 46.4% for the three months ended June 
30, 1998 from 46.9% for the three months ended June 30, 1997.  This decrease 
was primarily attributable to normal fluctuations in the mix of contracts 
worked. The Company anticipates that, as a percentage of sales, salaries, 
wages and related benefits will increase, with a corresponding decrease in 
subcontractor costs, due, in part, to the Company's May 1998 purchase of 
Interra Technologies, an India-based company that had been a provider of 
subcontractor services to the Company. 

     SUBCONTRACTOR COSTS.  Subcontractor costs include production costs 
incurred through the use of third parties for production tasks such as data 
conversion services to meet contract requirements, aerial photography and 
ground and airborne survey services. Subcontractor costs increased 169.6% to 
$3.8 million for the three months ended June 30, 1998 from $1.4 million for 
the three months ended June 30, 1997.  As a percentage of sales, however, sub 
contractor costs remained constant at 16.4% for both the three months ended 
June 30, 1998 and the three months ended June 30, 1997.

     OTHER GENERAL AND ADMINISTRATIVE COSTS.  Other general and 
administrative costs include rent, maintenance, travel, supplies, utilities, 
insurance and professional services. Such costs increased 184.4% to $3.9 
million for the three months ended June 30, 1998 from $1.4 million for the 
three months ended June 30, 1997, primarily due to greater supplies expense, 
increased travel, and employee recruiting and relocation expenses related to 
the integration of MSE. As a percentage of sales, other general and 
administrative costs increased to 17.3% for the three months ended June 30, 
1997 from 16.2% for the three months ended June 30, 1997. 

     DEPRECIATION AND AMORTIZATION.  Depreciation and amortization consists
primarily of amortization of goodwill incurred in connection with the Company's
acquisitions, as well as depreciation of certain of the Company's operating
assets. For the three months ended June 30, 1998, depreciation and amortization
increased 182.8% to $905,000 from $320,000 for the three months ended June 30,
1997. This increase was primarily attributable to the increased goodwill
recorded as a result of the MSE acquisition. As a percentage of sales,
depreciation and amortization increased slightly to 4.0% for the three months
ended June 30, 1998 from 3.8% for the three months ended June 30, 1997. The
Company expects amortization expense to increase substantially as a result of
the Cartotech acquisition.

                                JUNE 30, 1998


     OTHER EXPENSE, NET.  Other expense, net is comprised primarily of net
interest expense. Net interest expense increased 341.0% to $541,000 for the
three months ended June 30, 1998 from $123,000 for the three months ended June
30, 1997. This increase was primarily due to increased term debt incurred in
connection with the acquisition of MSE in July 1997 and increased utilization of
the Company's lines of credit for working capital. 

     INCOME TAX EXPENSE.  Income tax expense was $1.3 million for the three
months ended June 30, 1998 compared to $490,000 for the three months ended June
30, 1997. The Company's effective income tax rate for the three months ended
June 30, 1998 was 40.3%, an increase from 37.9% for the three months ended June
30, 1997, due to the change in the mix of state tax rates as a result of the MSE
acquisition. 

     NET EARNINGS.  Due to the factors discussed above, net earnings increased
135% to $1.9 million for the three months ended June 30, 1998 from $802,000 for
the three months ended June 30, 1997. 


NINE MONTHS ENDED JUNE 30, 1998 AND 1997

     SALES. Sales increased $35.5 million or 143.9% to $60.1 million for the
nine months ended June 30, 1998 from $24.6 million for the nine months ended
June 30, 1997. This increase was due to an increase in the number and size of
customer contracts with the Company (including MSE) as well as the impact of the
acquisition of MSE in July 1997. Prior to its acquisition by the Company, MSE's
sales for the nine months ended June 30, 1997 were $20.7 million. 

     SALARIES, WAGES AND RELATED BENEFITS. Salaries, wages and related benefits
increased 151.3% to $29.0 million for the nine months ended June 30, 1998 from
$11.5 million for the nine months ended June 30, 1997. This increase was
primarily due to the addition of over 325 employees as a result of the MSE
acquisition in July 1997, as well as the hiring of additional employees to
support the Company's increased business. As a percentage of sales, salaries,
wages and related benefits increased to 48.2% for the nine months ended June 30,
1998 from 46.8% for the nine months ended June 30, 1997. This increase, and the
corresponding decrease in subcontractor costs, was primarily attributable to the
Company's increased capability to perform more tasks internally as well as a
decrease in the number of projects which required subcontractor services. 
     
     SUBCONTRACTOR COSTS. Subcontractor costs increased 83.2% to $8.1 million
for the nine months ended June 30, 1998 from $4.4 million for the nine months
ended June 30, 1997, but decreased as a percentage of sales to 13.5% for the
nine months ended June 30, 1998 from 17.9% for the nine months ended June 30,
1997. 

     OTHER GENERAL AND ADMINISTRATIVE COSTS.  Other general and administrative
costs increased 161.4% to $10.5 million for the nine months ended June 30, 1998
from $4.0 million for the nine months ended June 30, 1997, primarily due to
greater supplies expenses, increased travel, and employee recruiting and
relocation expenses related to the integration of MSE. As a percentage of sales,
other general and administrative costs increased to 17.5% for the nine months
ended June 30, 1997 from 16.4% for the nine months ended June 30, 1997.

                                JUNE 30, 1998


     DEPRECIATION AND AMORTIZATION. For the nine months ended June 30, 1998,
depreciation and amortization increased 158.3% to $2.5 million from $973,000 for
the nine months ended June 30, 1997. This increase was primarily attributable to
the increased goodwill recorded as a result of the MSE acquisition. As a
percentage of sales, depreciation and amortization increased slightly to 4.2%
for the nine months ended June 30, 1998 from 3.9% for the nine months ended June
30, 1997. 
     
     OTHER EXPENSE, NET. Net interest expense increased 272.4% to $1.4 million
for the nine months ended June 30, 1998 from $382,000 for the nine months ended
June 30, 1997. This increase was primarily due to increased term debt incurred
in connection with the acquisition of MSE in July 1997 and increased utilization
of the Company's lines of credit for working capital. 

     INCOME TAX EXPENSE.  Income tax expense was $3.5 million for the nine
months ended June 30, 1998 compared to $1.3 million for the nine months ended
June 30, 1997. The Company's effective income tax rate for the nine months ended
June 30, 1998 was 39.7%, an increase from 38.1% for the nine months ended June
30, 1997, due to the change in the mix of state tax rates as a result of the MSE
acquisition. 

     NET EARNINGS.  Due to the factors discussed above, net earnings increased
154.8% to $5.2 million for the nine months ended June 30, 1998 from $2.1 million
for the nine months ended June 30, 1997. 


LIQUIDITY AND CAPITAL RESOURCES

     Historically, the Company's principal source of liquidity has consisted 
of cash flow from operations supplemented by secured lines of credit. On June 
3, 1998, the Company replaced its existing lines of credit with a three-year, 
$11.0 million secured working capital line of credit and a $10.0 million line 
of credit for acquisitions (which is due in quarterly installments over a 
five-year period), and the Company refinanced $16.0 million of term debt. 
Borrowings under the new credit facilities bear interest at a rate per annum 
equal to, at the Company's option, (i) the agent bank's prime rate or (ii) an 
adjusted London Interbank Offering Rate (LIBOR) plus a margin ranging from 
1.25% to 2.25%. The agent bank's prime rate was 8.25% on June 3, 1998. The 
Company borrowed approximately $8.9 million under the new acquisition line of 
credit to fund the cash portion of the acquisition of Cartotech, related 
transaction costs, retire existing Cartotech loans, and to provide working 
capital. As of June 30, 1998, the Company's outstanding balances on its 
working capital lines of credit were $7.4 million.

     On June 26, 1998, the Company filed a registration statement with the
United States Securities and Exchange Commission for an offering of 2,250,000
shares of common stock, 1,750,000 of which will be sold by the Company and the
remaining 500,000 shares of which will be sold by existing shareholders.  The
underwriters may exercise over allotment rights and increase the total offering
to 2,587,500 shares, of which 2,012,500 shares would be issued by the Company
and 575,000 shares would be sold by existing shareholders.  If the offering is
successfully completed, the Company expects to use a portion of the net proceeds
of the offering to repay substantially all of the outstanding term debt and line
of credit loans.

                        QUARTERLY REPORT ON FORM 10-Q
                                JUNE 30, 1998


     The Company's cash flow is significantly affected by three contract-related
accounts: accounts receivable; revenues in excess of billings; and billings in
excess of revenues. Under the percentage of completion method of accounting, an
"account receivable" is created when an amount becomes due from a customer,
which typically occurs when an event specified in the contract triggers a
billing. "Revenues in excess of billings" occur when the Company has performed
under a contract even though a billing event has not been triggered. "Billings
in excess of revenues" occur when the Company receives an advance or deposit
against work yet to be performed. These accounts, which represent a significant
investment by ASI in its business, affect the Company's cash flow as projects
are signed, performed, billed and collected. 

     Approximately $6.0 million in cash was used in operating activities for the
first nine months of fiscal 1998, compared to $2.7 million in cash generated for
the first nine months of fiscal 1997. The change in operating cash flows is
primarily attributable to normal fluctuations in the investment in
contract-related accounts. At June 30, 1998, the working capital in
contract-related accounts, excluding the newly acquired Cartotech balances, was
equivalent to 195 days sales outstanding, up from 189 days at March 31, 1998.
The Company believes that this level of investment is consistent with its normal
operating range of days sales outstanding. 

     For the nine months ended June 30, 1998, $11.0 million was used in
investing activities compared to $552,000 for the nine months ended June 30,
1997. Such investing activities principally consisted of payments for net assets
acquired in business combinations and purchases of equipment and leasehold
improvements. 

     For the nine months ended June 30, 1998, cash provided by financing
activities was $17.0 million compared to $748,000 in cash used for the nine
months ended June 30, 1997. Financing activities consisted primarily of net
borrowings and payments under lines of credit for working capital purposes and
net borrowings and payments of long-term debt used for business combinations and
the purchase of equipment and leasehold improvements. 

     The Company believes that funds available under its lines of credit and
cash flow from operations are adequate to finance its operations for at least
the next 18 months. 


RECENT ACCOUNTING PRONOUNCEMENTS

     The Company has adopted Statement of Financial Accounting Standards No. 128
"Earnings Per Share" ("SFAS 128"). SFAS 128 requires the restatement of all
prior-period earnings per share ("EPS") data. SFAS 128 replaces the presentation
of the primary EPS with a presentation of "basic EPS" and "diluted EPS." Under
SFAS 128, basic EPS excludes dilution for common stock equivalents and is
computed by dividing income available to common shareholders by the weighted
average number of common shares outstanding for the period. Diluted EPS reflects
the potential dilution that could occur if securities or other contracts to
issue common stock are exercised or converted into common stock or result in the
issuance of common stock that then share in the earnings of the entity. Under
SFAS 128, the Company's diluted EPS is the same as the income per share reported
by the Company prior to the adoption of SFAS 128, while the Company's basic EPS
is greater than the income per share as previously reported.

                                JUNE 30, 1998


     In June 1997, the FASB issued Statement of Financial Accounting Standards
No. 130, "Reporting Comprehensive Income." This statement requires that changes
in comprehensive income be shown in a financial statement that is displayed with
the same prominence as other financial statements. The statement will be
effective for fiscal years beginning after December 15, 1997 (the Company's
fiscal year beginning October 1, 1998). Reclassification for earlier periods is
required for comparative purposes. The Company is currently evaluating the
impact this statement will have on its financial statements; however, because
the statement requires only additional disclosure, the Company does not expect
the statement to have a material impact on its financial position or results of
operations. 

     In June 1997, the FASB issued Statement of Financial Accounting Standards
No. 131, "Disclosures About Segments of an Enterprise and Related Information."
This statement supersedes Statement of Financial Accounting Standards No. 14,
"Financial Reporting for Segments of a Business Enterprise." This statement
includes requirements to report selected segment information quarterly and
entity-wide disclosures about products and services, major customers, and the
material countries in which the entity holds assets and reports revenues. The
statement will be effective for fiscal years beginning after December 15, 1997
(the Company's fiscal year beginning October 1, 1998). Reclassification for
earlier periods is required, unless impracticable, for comparative purposes. The
Company is currently evaluating the impact this statement will have on its
financial statements; however, because the statement requires only additional
disclosure, the Company does not expect the statement to have a material impact
on its financial position or results of operations.


YEAR 2000 ISSUES

     The "Year 2000" issue concerns the potential exposures related to the
automated generation of business and financial misinformation resulting from the
application of computer programs that have been written using two digits, rather
than four, to define the applicable year. The Company and the third parties with
which it does business rely on numerous computer programs in their daily
operations. The Company has assessed its internal exposure to this issue and is
in the process of upgrading or replacing systems where necessary. The Company
does not believe that the costs to upgrade or replace such systems will be
material, and such costs will be expensed as incurred. The Company's customers
specify database designs, including date fields, and the Company's delivery of
data conforms to such specifications. Accordingly, the Company has not formally
evaluated the Year 2000 issue as it relates to the computer systems used by its
customers and potential customers. 



PART II OTHER INFORMATION

Item 2. Legal Proceedings
     
     The Company is not a party to any material pending legal proceeding nor 
is its property the subject of a pending legal proceeding. The Company is 
involved in routine litigation from time to time, which is incidental to the 
business and the outcome of which is not expected to have a material effect 
on the Company.

<PAGE>

          will make available to the Agent, at its address referred to in

          the aggregate amount of such Revolving Loan or Acquisition Loan

          Revolving Loan or Acquisition Loan shall not relieve any other Bank 
          from its several obligation hereunder to make available to the

          make available to the Borrower a corresponding amount. If any
          Bank makes available to the Agent such amount on a date after
          such day of Advance, such Bank shall pay to the Agent on demand
          an amount equal to the product of (i) the Federal Funds Rate each

          Loan or Acquisition Loan shall become immediately available to
          the Agent, and the denominator of which is 360.  A statement of
          the Agent submitted to such Bank with respect to any amounts

<PAGE>

               (ii) After the Acquisition Loans Draw Date, twenty (20)
               consecutive quarterly principal payments on the last
               Business Day of each Fiscal Quarter in equal amounts, plus
               interest payable in accordance with SECTION 2.10.

          (d)  MANDATORY REPAYMENT.
 
               (i)  The Borrower will repay the Loans in full on demand
               upon the acceleration of the due date of any of the Loans by
               the Agent pursuant to ARTICLE VI hereof.

               (ii) The Borrower shall pay to the Agent Net Proceeds
               within not more than five (5) Business Days after the
               Borrower shall receive Net Proceeds from(x) Dispositions,
               (y) any equity securities issuance or sale or (z) insurance
               recoveries and condemnation and eminent domain awards.
               Collateral shall be released from the liens of the
               Collateral Documents upon any Disposition of such
               Collateral, provided that (i) no Event of Default has
               occurred and (ii) the Borrower shall have made the mandatory
               repayment required under the terms of this SECTION 2.6.

          (e)  APPLICATION OF REPAYMENTS.  All voluntary Loan repayments
          received by the Agent from the Borrower will be applied to the
          Revolving Loans, Acquisition Loans and Term Loans as the Borrower
          shall instruct the Agent in writing concurrently with the
          payment, and in the absence of such written instructions, will be
          applied first to the Revolving Loans until they are repaid in
          full, then to the Acquisition Loans until they are repaid in full
          and finally to the Term Loan.  All mandatory Loan repayments will
          be applied first to reduce the Term Loan until the Term Loan is
          paid in full, then to the repayment of the Acquisition Loans
          until they are paid in full and finally to the repayment of the
          Revolving Loans.  All repayments of the Term Loan and Acquisition
          Loans will be applied to the principal payments due with respect
          to the such Loans in inverse order of maturity.

     SECTION 2.7   DISTRIBUTION OF PAYMENTS BY THE AGENT.

     The Agent shall promptly distribute to each Bank its Pro Rata Share of
each payment received by the Agent under the Loan 



                                      -28-
<PAGE>

Instruments for the account of the Banks by credit to an account of such Bank 
at the Agent's Bank identified at SECTION 8.2 or by wire transfer to an 
account of such Bank.

     Unless the Agent shall have received notice from the Borrower prior to
the date on which any payment is due to the Banks under the Loan
Instruments that the Borrower will not make such payment in full, the Agent
may assume that the Borrower has made such payment in full to the Agent on
such date and the Agent in its sole discretion may, in reliance upon such
assumption, cause to be distributed to each Bank on such due date a
corresponding amount with respect to the amount then due such Bank.  If and
to the extent the Borrower shall not have so made such payment in full to
the Agent and the Agent shall have so distributed to any Bank a
corresponding amount, such Bank shall, on demand, repay to the Agent the
amount so distributed together with interest thereon, for each day from the
date such amount is distributed to such Bank until the date such Bank
repays such amount to the Agent at the Prime Rate.

     SECTION 2.8   PROMISSORY NOTES.

          (a)  THE REVOLVING NOTES.  The Revolving Loans shall be evidenced
          by promissory notes of the Borrower in substantially the form of
          EXHIBIT A-1 hereto (each a "REVOLVING NOTE"), dated as of the
          Effective Date and completed with appropriate insertions.  One
          Revolving Note shall be payable to the order of each Bank in a
          principal amount equal to such Bank's Revolving Loans Commitment
          or, if different, the outstanding amount of all Revolving Loans
          made (or held) by such Bank, plus interest accrued thereon, as
          set forth below.  The Borrower irrevocably authorizes each Bank
          to make or cause to be made, at or about the time of an Advance
          of any Revolving Loan or at the time of receipt of any payment of
          principal on such Bank's Revolving Note, an appropriate notation
          on such Revolving Note Record reflecting the making of such
          Revolving Loan or (as the case may be) the receipt of such
          payment.  The outstanding amount of the Revolving Loans set forth
          on such Bank's Revolving Note Record shall be PRIMA FACIE
          evidence of the principal amount thereof owing and unpaid to such
          Bank absent manifest error, but the failure to record, or any
          error in so recording, any such amount shall not affect the
          obligation of the Borrower hereunder or under any Revolving Note
          to make payments of principal of or interest on any Revolving
          Note when due. 


                                     -29-
<PAGE>

          (b)  TERM NOTES.  The Term Loans shall be evidenced by promissory
          notes of the Borrower in substantially the form of EXHIBIT A-2
          hereto (each a "TERM NOTE"), dated the Effective Date and
          completed with appropriate insertions.  One Term Note shall be
          payable to the order of each Bank in a principal amount equal to
          such Bank's Term Loan Commitment and representing the obligation
          of the Borrower to pay to such Bank such principal amount or, if
          less, the outstanding amount of such Bank's Term Loan Commitment,
          plus interest accrued thereon, as set forth below.  The Borrower
          irrevocably authorizes each Bank to make or cause to be made a
          notation on such Bank's Term Note Record reflecting the original
          principal amount of such Bank's Term Loan Commitment and, at or
          about the time of such Banks' receipt of any principal payment on
          such Bank's Term Note, an appropriate notation on such Bank's
          Term Note Record reflecting such payment.  The aggregate unpaid
          amount set forth on such Bank's Term Note Record shall be PRIMA
          FACIE evidence of the principal amount thereof owing and unpaid
          to such Bank absent manifest error, but the failure to record, or
          any error in so recording, any such amount on such Bank's Term
          Note Record shall not affect the obligation of the Borrower
          hereunder or under any Term Note to make payments of principal of
          and interest on any Term Note when due.

          (c)  ACQUISITION LOAN NOTE. The Acquisition Loans shall be
          evidenced by promissory notes of the Borrower in substantially
          the form of EXHIBIT A-3 hereto (each a "ACQUISITION LOAN NOTE"),
          dated as of the Effective Date and completed with appropriate
          insertions.  One Acquisition Loan Note shall be payable to the
          order of each Bank in a principal amount equal to such Bank's
          Acquisition Loan Commitment or, if different, the outstanding
          amount of all Acquisition Loans made (or held) by such Bank, plus
          interest accrued thereon, as set forth below.  The Borrower
          irrevocably authorizes each Bank to make or cause to be made, at
          or about the time of an Advance of any Acquisition Loan or at the
          time of receipt of any payment of principal on such Bank's
          Acquisition Loan Note, an appropriate notation on such
          Acquisition Loan Note Record reflecting the making of such
          Acquisition Loan or (as the case may be) the receipt of such
          payment.  The outstanding amount of the Acquisition Loans set
          forth on such Bank's Acquisition Loan Record shall be PRIMA FACIE
          evidence 


                                      -30-
<PAGE>

          of the principal amount thereof owing and unpaid to such
          Bank absent manifest error, but the failure to record, or any
          error in so recording, any such amount on such Bank's Acquisition
          Loan Note Record shall not affect the obligation of the Borrower
          hereunder or under any Acquisition Loan Note to make payments of
          principal and interest on any Acquisition Loan Note when due. 

     SECTION 2.9   PRO RATA TREATMENT.  Except to the extent otherwise
provided herein, (a) Loans shall be made by the Banks pro rata in
accordance with their respective Commitments, (b) Loans of the Banks shall
be Converted and continued pro rata in accordance with their respective
amounts and Type and, in the case of LIBOR Rate Loans, having the Interest
Period being so Converted or continued, (c) each reduction in the Revolving
Loans Commitment, Acquisition Loan Commitment and the Term Loan Commitment
shall be made pro rata in accordance with the respective amounts thereof
and (d) each payment of the principal of or interest on the Loans shall be
made for the account of the Banks pro rata in accordance with their
respective amounts thereof then due and payable.

     SECTION 2.10  INTEREST.  The Borrower shall pay interest on the
unpaid principal amount of each Loan from the date of the Advance thereof
comprising such Loan until (but not including) the date such principal
amount has been repaid in full, at the following rates per annum:

          (a)  PRIME RATE LOANS.  During such periods as such Loan is a
          Prime Rate Loan, at a rate per annum equal at all times to the
          Prime Rate PLUS Applicable Margin or the Default Rate, whichever
          is applicable.  Prime Rate interest PLUS the Applicable Margin
          shall be payable quarterly in arrears, on the first day of each
          Fiscal Quarter.  Interest accruing at the Default Rate shall be
          payable on demand.

          (b)  LIBOR RATE LOANS.  During such periods as such Loan is a
          LIBOR Rate Loan, at a rate per annum during the Interest Period
          for such Loan equal to the LIBOR Rate or the Default Rate,
          whichever is applicable.  LIBOR Rate interest will be payable on
          termination of the Interest Period applicable to the Loan, and,
          if such Interest Period is longer than 3 months, then every 3
          months.  Interest accruing at the Default Rate shall be payable
          on demand.

                                     -31-
<PAGE>

          (c)  DEFAULT RATE INTEREST.  Subject to the provisions of
          SECTION 6.2, all outstanding Loans will bear interest at the
          Default Rate during all periods when an Event of Default has
          occurred and is continuing.

          (d)  INTEREST CALCULATIONS.  Interest on the Loans shall be
          computed on a 365/360 simple interest basis, by applying the
          ratio of the applicable annual interest rate over a year of 360
          days, multiplied by the outstanding principal balance, multiplied
          by the actual number of days the principal balance is
          outstanding.

     SECTION 2.11  YIELD PROTECTION.  In order to protect the yield of the
Banks in connection with the Advances to be made hereunder, the Borrower
agrees as follows.

          (a)  INCREASED COSTS.  If, due to either (i) the introduction of
          or any change in or in the interpretation of any law or
          regulation, or (ii) the compliance with any guideline or request
          from any central bank or other Governmental Authority (whether or
          not having the force of law), there shall be any increase in the
          cost to the Banks of agreeing to make or making, funding or
          maintaining LIBOR Rate Loans, then the Borrower shall from time
          to time, upon demand by a Bank through the Agent, pay to such
          Bank additional amounts sufficient to compensate the Bank for
          such increased cost.  A certificate as to the amount of such
          increased cost, shall be submitted to the Borrower by the Agent. 
          Such certificate shall show in reasonable detail the Bank's
          computations of its increased costs.  Notwithstanding the
          foregoing, there shall be no duplication of costs to the Borrower
          as the result of the application of SECTION 2.11(b).  Such
          certificate of increased costs shall be conclusive and binding
          for all purposes, absent manifest error.

          (b)  ADDITIONAL INTEREST.  The Borrower shall pay to the Banks,
          so long as the Banks shall be required under regulations of the
          Board of Governors of the Federal Reserve System to maintain
          reserves with respect to liabilities or assets consisting of or
          including Eurocurrency liabilities (as such term is defined in
          Regulation D of the Board of Governors of the Federal Reserve
          System, as in effect from time to time), additional interest on
          the unpaid principal amount of each LIBOR Rate Loan, from the
          date of the Advance thereof until the principal amount thereof is
          paid in 

                                      -32-
<PAGE>

          full, at an interest rate per annum equal at all times to
          the remainder obtained by subtracting (i) the LIBOR Rate for the
          Interest Period for such Loan from (ii) the rate obtained by
          dividing such LIBOR Rate by a percentage equal to 100% minus the
          reserve percentage applicable during such Interest Period (or if
          more than one such percentage shall be so applicable, the daily
          average of such percentages for those days in such Interest
          Period during which any such percentage shall be so applicable)
          under regulations issued from time to time by the Board of
          Governors of the Federal Reserve System (or any successor) for
          determining the maximum Reserve Requirement (including, without
          limitation, any emergency, supplemental or other marginal reserve
          requirement) for the Banks with respect to liabilities or assets
          consisting of or including Eurocurrency liabilities having a term
          equal to such Interest Period, payable on each date on which
          interest is payable on such Loan.  Such additional interest shall
          be determined by the Agent and a certificate as to the amount
          shall be submitted to the Borrower.  Such certificate shall show
          in reasonable detail the Agent's computations.  Such certificate
          of additional interest shall be conclusive and binding for all
          purposes, absent manifest error.  

          (c)  INCREASED CAPITAL.  If a Bank determines that compliance
          with any law or regulation or any guideline or request from any
          central bank or other Governmental Authority (whether or not
          having the force of law) affects or would affect the amount of
          capital required or expected to be maintained by the Bank or any
          corporation controlling the Bank and that the amount of such
          capital is increased by or based upon the existence of the Bank's
          commitment to lend hereunder and other commitments of this type,
          then, upon demand by the Bank through the Agent, the Borrower
          shall immediately pay to the Bank, from time to time as specified
          by the Bank, additional amounts sufficient to compensate the Bank
          or such corporation in the light of such circumstances, to the
          extent that the Bank reasonably determines such increase in
          capital to be allocable to the existence of the Bank's commitment
          to lend hereunder.  A certificate as to such amounts submitted to
          the Borrower by the Agent or a Bank, shall be conclusive and
          binding for all purposes, absent manifest error.  Such
          certificate shall show in 


                                      -33-
<PAGE>

          reasonable detail the Agent's or the Bank's computations.

          (d)  BREAKAGE COSTS.  If any payment of principal of any LIBOR
          Rate Loan is made other than on the last day of the Interest
          Period for such Loan as a result of  acceleration of the maturity
          of the Loans and the Notes pursuant to SECTION 6.2, or for any
          other reason, the Borrower shall, upon demand by the Agent, hold
          the Banks harmless and pay to the Banks, through the Agent, any
          amounts required to compensate the Banks for additional losses,
          costs or expenses which they may incur as a result of such
          payment, including, without limitation, any loss, cost or expense
          incurred by reason of the liquidation or reemployment of deposits
          or other funds acquired by the Banks to fund or maintain such
          Advance provided, however, that such loss or expense shall not
          include loss of Applicable Margin.  Such payment shall be
          calculated as though the Banks funded the principal amount
          prepaid through the purchase of Dollar deposits in the London,
          England interbank market having a maturity corresponding to such
          Interest Period and bearing an interest rate equal to the LIBOR
          Rate less the Applicable Margin for such Interest Period, whether
          in fact that is the case or not.  The Agent's determination of
          the amount of such payment shall be conclusive in the absence of
          manifest error.

     SECTION 2.12  CONVERSION OF LOANS; CHANGE OF INTEREST PERIODS.  At
any time, with respect to Prime Rate Loans, and at any time not less than
three (3) Business Days prior to the end of the then current Interest
Period for any LIBOR Rate Loan, the Borrower may elect, by delivery to the
Bank of an Interest Period/Conversion Notice in the form of EXHIBIT B-3
duly executed by an Authorized Signatory, to Convert the Type of Advance
or, with respect to LIBOR Rate Loans, to select an Interest Period for such
Advance as permitted herein.  If the Borrower fails to select the duration
of any Interest Period for any LIBOR Rate Loan in the foregoing manner,
such Advance will, unless paid in full on the last day of such Interest
Period, automatically, on the last day of the then existing Interest Period
therefor, Convert into a Prime Rate Loan.

     SECTION 2.13  ILLEGALITY, ETC.

          (a)  Notwithstanding any other provision of this Agreement, if
          the Agent or a Bank shall notify the


                                      -34-
<PAGE>
          Borrower that the introduction of or any change in or in the 
          interpretation of any law or regulation makes it unlawful, or any 
          central bank or other Governmental Authority asserts that it is 
          unlawful, for a Bank to perform its obligations hereunder to make 
          LIBOR Rate Loans or to fund LIBOR Rate Loans hereunder, (i) the 
          obligation of the Bank to make, or to Convert Loans into LIBOR Rate 
          Loans shall be suspended until the Bank shall notify the Borrower 
          that the circumstances causing such suspension no longer exist and 
          (ii) the Borrower shall prepay in full all LIBOR Rate Loans of the 
          Bank then outstanding, together with interest accrued thereon, either 
          on the last day of the Interest Period thereof if the Banks may 
          lawfully continue to maintain LIBOR Rate Loans to such day, or 
          immediately, if the Banks may not lawfully continue to maintain LIBOR 
          Rate Loan, unless the Borrower, within five (5) Business Days of 
          notice from the Bank, Converts all LIBOR Rate Loans of the Bank then 
          outstanding into Prime Rate Loans in accordance with SECTION 2.12.

          (b)  If, with respect to any LIBOR Rate Loan, a Bank notifies the
          Borrower that the LIBOR Rate for any Interest Period for such
          Advance will not adequately reflect the cost to the Bank, in the
          Bank's reasonable judgement, of making, funding or maintaining
          such LIBOR Rate Loan for such Interest Period, such LIBOR Rate
          Loan will automatically, on the last day of the then existing
          Interest Period therefor, Convert into a Prime Rate Loan, and the
          obligation of the Bank to make, or to Convert Advances into,
          LIBOR Rate Loans shall be suspended until the Bank shall notify
          the Borrower that the circumstances causing such suspension no
          longer exist.  Upon receipt of such notice, the Borrower may
          revoke any Request for Advance or Interest Period/Conversion
          Notice then submitted by it.  If the Borrower does not revoke
          such request or notice, the Bank shall make, Convert or continue
          the Loan, as proposed by the Borrower, in the amount specified in
          the applicable request or notice submitted by the Borrower, but
          such Loan shall be made, Converted or continued as a Prime Rate
          Loan instead of a LIBOR Rate Loan.

     SECTION 2.14  PAYMENTS AND COMPUTATIONS.

          (a)  The Borrower shall make each payment under any Loan Instrument 
          not later than 12:00 noon (Denver,


                                     -35-

<PAGE>

          Colorado time) on the day when due in Dollars to the Agent at its 
          address referred to in SECTION 8.2 in same day funds.

          (b)  The Borrower hereby authorizes the Agent, if and to the extent 
          payment is not made when due, subject to the expiration of applicable 
          grace periods, under any Loan Instrument, to charge from time to time 
          against the Borrower's Account or any or all other accounts of the 
          Borrower with the Agent any amount so due.

          (c)  All computations of interest and of Fees shall be made by the 
          Agent on the basis of a year of 360 days, in each case for the actual 
          number of days (including the first day but excluding the last day) 
          occurring in the period for which such interest or Commitment Fees 
          are payable.  Each determination by the Agent of an interest rate 
          hereunder shall be conclusive and binding for all purposes, absent 
          manifest error, on the Borrower and the Banks.

          (d)  Whenever any payment under any Loan Instrument shall be stated 
          to be due on a day other than a Business Day, such payment shall be 
          made on the next succeeding Business Day, and such extension of time 
          shall in such case be included in the computation of payment of 
          interest or the Commitment Fee, as the case may be; PROVIDED, 
          HOWEVER, if such extension would cause payment of interest on or 
          principal of LIBOR Rate Loans to be made in the next following 
          calendar month, such payment shall be made on the next preceding 
          Business Day.

                                  ARTICLE III

                             CONDITIONS OF LENDING


     SECTION 3.1   CONDITIONS PRECEDENT TO INITIAL ADVANCE.  The obligation 
of the Banks to make the initial Advance of the Loans is subject to the 
satisfaction (or waiver by the Banks in their sole discretion) of the

          there is no pending, or to the Borrower's knowledge, threatened
          action or proceeding affecting the Borrower or any of its
          properties or business activities or any of the Guarantors or
          their respective properties or business activities, before any
          court, governmental agency or arbitrator, in which there is a
          reasonable possibility of a Material Adverse Effect or which
          purports to affect the legality, validity or enforceability of
          this Agreement or any Loan Instrument to which the Borrower or
          any Guarantor will be a party.

          (h)  FEDERAL RESERVE REGULATIONS.  None of the Advances to be
          provided to the Borrower hereunder will be used in violation of
          Regulations T, U or X.  The Borrower is not engaged in the
          business of extending credit for the purpose, whether immediate,
          incidental or ultimate, of buying or carrying Margin Stock
          (within the meaning of Regulations T, U and X).  No part of the
          proceeds of any extension of credit hereunder, whether directly
          or indirectly, and whether immediately, incidentally or
          ultimately, will be used (i) to purchase or carry Margin Stock or
          to extend credit to others for the purpose of purchasing or
          carrying Margin Stock or to refund indebtedness originally
          incurred for such purpose, or (ii) for any purpose which entails
          a violation of, or which is inconsistent with, the provisions of
          the Regulations of the Board of governors of the Federal Reserve
          system, including Regulations T, U or X.

          (i)  INVESTMENT COMPANY ACT.  The Borrower is not an "investment
          company' or a company "controlled" by an "investment company"
          within the meaning of the Investment Company Act of 1940, as
          amended.

          (j)  ERISA.

               (i)      The Borrower and Guarantors neither maintain nor
               contribute to any Employee Benefit Plan or Multiemployer
               Plan other than those specified in SCHEDULE 4.1(j).

               (ii)     The Borrower and the Guarantors are in compliance in 
               all material respects with all applicable provisions of ERISA 
               and the Code with


                                    -44-

<PAGE>


               respect to all Employee Benefit Plans.  Each Employee Benefit 
               Plan that is intended to be qualified under Section 401(a) of 
               the Code has been determined by the Internal Revenue Service 
               to be so qualified, and each trust related to such Plan has 
               been determined to be exempt from federal income tax under 
               Section 501(a) of the Code.  The actuarial present value of 
               all accumulated benefit obligations under each Plan, as 
               disclosed in the most recent actuarial report with respect to 
               such Plan, do not exceed the fair market value of the assets 
               of such Plan.  No material liability has been incurred by the 
               Borrower, any Guarantor or any of their ERISA Affiliates which 
               remains unsatisfied for any taxes, penalties or other amount 
               (other than contributions in the ordinary course) with respect 
               to any Employee Benefit Plan or any Multiemployer Plan, and to 
               the best knowledge of the Borrower no such material liability 
               is expected to be incurred.

               (iii) The Borrower and the Guarantors have not
               (a) engaged in a nonexempt prohibited transaction described

               (i)   The Borrower and each Guarantor:  (a) has filed all

               other sureties as required by law have been posted by the
               Borrower or Guarantor.

               (ii)  The Borrower and each Guarantor is current in its

          (p)  FINANCIAL CONDITION.  Neither the Borrower nor any Guarantor
          is entering into the arrangements contemplated by this Agreement
          and the other Loan Instruments with actual intent to hinder,
          delay or defraud either present or future creditors of the
          Borrower or any Guarantor.  On and as of the date of execution
          hereof by the Borrower, and on and as of the date of each Advance
          hereunder by the Banks, on a pro-forma basis 


                                 -47-
<PAGE>


          after giving effect to the transactions contemplated by the Loan 
          Instruments and to all indebtedness (including Debt) incurred or 
          to be created in connection herewith:

               (i)   the present fair saleable value of the assets of the
               Borrower and each Guarantor, respectively, (on a going
               concern basis) will exceed the probable liability of the
               Borrower and each Guarantor, respectively, on its
               indebtedness (including Debt and contingent obligations);

               (ii)  the Borrower and each Guarantor, respectively, has
               not incurred, nor does Borrower intend to or believe it will
               incur, nor will Borrower permit any Guarantor to incur
               indebtedness (including Debt and contingent obligations)
               beyond its ability to pay such indebtedness as such
               indebtedness matures (taking into account the timing and
               amounts of cash to be received from any source, and of
               amounts to be payable on or in respect of such
               indebtedness); and the amount of cash available to the
               Borrower and Guarantors after taking into account all other
               anticipated uses of funds is anticipated to be sufficient to
               pay all such amounts on or in respect of its respective
               indebtedness (including Debt and contingent liabilities)
               when such amounts are required to be paid; and

               (iii) the Borrower and each Guarantor will have sufficient 
               capital with which to conduct its present and proposed 
               business, and the assets of the Borrower and each Guarantor, 
               respectively, do not constitute unreasonably small capital 
               with which to conduct its present or proposed business.

          (q)  INSURANCE.  The Borrower and each of the Guarantors
          currently maintains with financially sound and reputable insurers
          insurance concerning its assets and business, with such
          deductibles and retentions and having coverages against risks,
          losses or damages as are customarily carried by reputable
          companies in the same or similar businesses, such insurance being
          in amounts no less than those amounts which are customary for
          such companies under similar circumstances, which third-party
          insurance coverages are identified in SCHEDULE 4.1(q).

          (r)  FULL DISCLOSURE.  No representation or warranty contained in
          this Agreement or in any other Loan Instrument to which the
          Borrower is a party, or in any other document furnished from time
          to time by the Borrower to the Bank pursuant to this Agreement,
          contains any untrue statement of a material fact or omits to
          state any material fact necessary to make the statements herein
          or therein not misleading in any material respect as of the date
          made or deemed to be made.  Except as may be set forth herein or
          in any of the Schedules hereto or in the certificates and
          information furnished pursuant to SECTION 5.1(b), there is no
          fact known to the Borrower which has had, or is reasonably
          expected to have, a Material Adverse Effect.

          (s)  NO DEFAULT.  No Default or Event of Default has occurred and
          is continuing.

          (t)  STATUS OF LOANS AS SENIOR DEBT.  All Debt of the Borrower to
          the Banks and the Agent in respect of the Loans constitutes
          "Senior Debt" or "Senior Indebtedness" (or the analogous term
          used therein) under the terms of any instrument evidencing or
          pursuant to which there is issued indebtedness which purports to
          be Debt of the Borrower.

          (u)  SWAP OBLIGATIONS.  Neither the Borrower nor any of its
          Subsidiaries has incurred any outstanding obligations under any
          Swap Contracts, other than Permitted Swap Obligations.  The
          Borrower has undertaken its own independent assessment of its
          consolidated assets, liabilities and commitments and has
          considered appropriate means of mitigating and managing risks
          associated with such matters and has not relied on any swap
          counterparty or any Affiliate of any swap counterparty in
          determining whether on not to enter into any Swap Contract.

          (v)  FRANCHISES, PATENTS, COPYRIGHTS, ETC.  The Borrower and the
          Subsidiaries possess all franchises, patents, copyrights,
          trademarks, trade names, licenses and permits, and rights in
          respect of the foregoing, adequate for the conduct of their
          business as now conducted without known conflict with any rights
          of others.

               such Fiscal Year, setting forth in comparative form the
               corresponding consolidated figures for such Fiscal Year and
               the prior Fiscal Year, each accompanied by a report of the

               of any condition or event which constitutes a Default or Event 
               of Default hereunder, or if such auditors have obtained 
               knowledge of any such condition or event, specifying in such 
               report each such condition or event of which they have 
               knowledge and the nature and status thereof; PROVIDED, 
               HOWEVER, that such auditors shall not be liable to the Banks 
               by reason of any failure to obtain knowledge of any condition 
               or event which constitutes a Default or Event of Default that

          manner adverse to the Bank; or amend, modify, cancel, terminate,
          waive any default under or breach of, in any manner any Material
          Agreement other than in the ordinary course of business or permit
          any Guarantor to do any of the foregoing; or enter into any new
          agreement that is inconsistent with the obligations of the
          Borrower or Guarantor under any Loan Instrument to which such
          Person is a party, without the prior written consent of the
          Required Banks, which consent shall not be unreasonably withheld. 
          The Borrower further agrees that it will not be in default under,
          or otherwise fail to perform and will not permit any Guarantor to
          be in default under or


                                      -62-
<PAGE>


          otherwise fail to perform all of its material obligations under
          any of the Material Agreements to which any such Person is a
          party.

          (j)  DIVIDENDS.  Declare or pay or permit any Guarantor to
          declare or pay cash or stock dividends or other distributions
          with respect to the Borrower's stock or Guarantor's stock, except
          that () any Guarantor may declare and pay dividends and make
          distributions to the Borrower and (ii) the Borrower may declare
          and pay a dividend payable solely in the capital stock of the
          Borrower.

          (k)  ACCOUNTING.  Change, or permit any Guarantor to change its
          respective Fiscal Years or accounting methods or practices
          (except to conform to changes in GAAP).  If any preparation of
          the financial statements referred to in SECTION 4.1(f), hereafter
          occasioned by the promulgation of rules, regulations,
          pronouncements and opinions by or required by the Financial
          Accounting Standards Board or the American Institute of Certified
          Public Accountants (or successors thereto or agencies with
          similar functions) result in a material change in the method of
          calculation of financial covenants, standards or terms found in
          this Agreement, the Borrower will, and will cause each Guarantor
          to, enter into good faith negotiations with the Bank in order to
          amend such provisions so as to equitably reflect such changes
          with the desired result that the criteria for evaluating the
          Borrower's consolidated financial condition shall be the same
          after such changes as if such changes had not been made.  Unless
          and until such provisions have been so amended, the provisions of
          this agreement shall govern and the financial covenants hereunder
          shall be calculated using GAAP as in effect prior to such
          changes.

          (l)  CHANGE OF ADDRESS; BUSINESS NAME(S).  Except upon not less
          than 30 days prior written notice to the Agent, change or permit
          any Guarantor to change the address at which the Borrower or such
          Guarantor maintains its chief executive offices and principal
          place of business; nor conduct its business activities under any
          names other than those set forth SCHEDULE 4.1(b) hereto unless
          the Borrower notifies the Agent of any such new name not less
          than 30 days prior to beginning use of such new name, except that
          no more than seven days notice shall be required in the case of


                                    -63-
<PAGE>


          a new name resulting from an acquisition of a business or assets by
          the Borrower.

          (c)  OTHER LOAN INSTRUMENT OBLIGATIONS.  (i) The Borrower shall
          fail to perform or observe any term, covenant or agreement
          contained in SECTION 5.2, or (ii) the Borrower shall fail to
          perform or observe any term, covenant or agreement contained in
          any Loan Instrument to which it is a party (other than any such
          failures addressed by SUBSECTIONS (a), (b) and (c)(i) above in
          this SECTION 6.1) and such failure continues unremedied for a
          period of 15 days after the Borrower receives notice or otherwise
          has actual knowledge thereof, or (iii) any Guarantor shall fail

          any Debt which is outstanding in a principal amount of at least 
          $1,000,000 in the aggregate (but excluding Debt evidenced by the 
          Notes) of such Person, when the same becomes due and payable 
          (whether by scheduled maturity, required prepayment, acceleration, 
          demand or otherwise), and such failure shall continue after the 
          applicable grace period, if any, specified in the agreement or 
          instrument relating to such Debt; or any other event shall occur or 
          condition shall exist under any agreement or instrument relating to 
          any such Debt and shall continue after the applicable grace period, 
          if any, specified in such agreement or instrument, if the effect of 
          such event or condition is to accelerate, or to permit the 
          acceleration of, the maturity of such Debt; or any such Debt shall 
          be declared to be due and payable, or required to be prepaid (other 
          than by a regularly scheduled required prepayment), redeemed,

          insolvent, or seeking liquidation, winding up, reorganization,
          arrangement, adjustment, protection, relief, or composition of it
          or its debts under any law relating to bankruptcy, insolvency or

          order for relief or the appointment of a receiver, trustee,
          custodian or other similar official for it or for any substantial
          part of its property and, in the case of any such proceeding
          instituted against it (but not instituted by it), either such
          proceeding shall remain undismissed or unstayed for a period of
          45 days, or any of the actions sought in such proceeding
          (including, without limitation, the entry of an order for relief
          against, or the appointment of a receiver, trustee, custodian or
          other similar official for, it or for any substantial part of its
          property) shall occur; or Borrower or any Guarantor shall take

          been commenced by any creditor upon such judgment or order or
          (ii) there shall be any period of thirty (30) consecutive days

          this Agreement, the Notes, or any of the Collateral Documents
          shall for any reason cease to be valid and binding on the
          Borrower or Guarantors (as the case may be), or the Borrower or
          any of the Guarantors shall so state in writing.

          (h)  COLLATERAL LIENS.  The Deeds of Trust, Security Agreements,
          Pledge Agreement or Collateral Assignment of Leases shall, after

accrued interest on the Loans and all other amounts payable under this
Agreement, the Notes and any other Loan Instrument to be forthwith due and
payable, whereupon the Notes, all such interest and all such amounts shall
become and be forthwith due and payable, without presentment, demand,
protest, or further notice of any kind, all of which are hereby expressly
waived by the Borrower, and (iii) may exercise the Banks rights and
remedies under the Loan Instruments and such other rights and remedies as
may be available to the Banks at law or in equity; PROVIDED, HOWEVER, that
in the event of an actual or deemed entry of an order for relief with
respect to the Borrower or any of the Guarantors 

                                     -66-

                                   ARTICLE VII

                                    THE AGENT

     SECTION 7.1   APPOINTMENT AND POWERS.  Each Bank hereby irrevocably 
appoints and authorizes Bank One, Colorado, N.A., and Bank One, Colorado, 
N.A. hereby agrees, to act as the agent for and representative (within the 
meaning of Section 9-105(m) of the Uniform Commercial Code) of such Bank 
under the Loan Instruments with such powers as are delegated to the Agent and 
the Secured Party by the terms thereof, together with such other powers as 
are reasonably incidental thereto.  The Agent's duties shall be purely 
ministerial and it shall have no duties or responsibilities except those 
expressly set forth in the Loan Instruments.  The Agent shall not be required 
under any circumstances to take any action that, in its judgment, (a) is 
contrary to any provision of the Loan Instruments or Applicable Law or (b) 
would expose it to any Liability or expense against which it has not been 
indemnified to its satisfaction.  The Agent shall not, by reason of its 
serving as the Agent, be a trustee or other fiduciary for any Bank. 

     SECTION 7.2   LIMITATION ON AGENT'S LIABILITY.  Neither the Agent nor 
any of its directors, officers, employees or agents shall be liable or 
responsible for any action taken or omitted to be taken by it or them under 
or in connection with the Loan Instruments, except for its or their own gross 
negligence, willful misconduct or knowing violations of law.  The Agent shall 
not be responsible to any Bank for (a) any recitals, statements, 
representations or warranties contained in the Loan Instruments or in any 
certificate or other document referred to or provided for in, or received by 
any of the Banks under, the Loan Instruments, (b) the validity, effectiveness 
or enforceability of the Loan Instruments or any such certificate or other 
document, (c) the value or sufficiency of the Collateral or (d) any failure 
by the Borrower or other parties to the Loan Instruments to perform any of 
their obligations under the Loan Instruments. The Agent may employ agents and 
attorneys-in-fact and shall not be responsible for the negligence or 
misconduct of any such agents or attorneys-in-fact so long as the Agent was 
not grossly 

                                    -67-

<PAGE>

negligent in selecting or directing such agents or attorneys-in-fact.  The 
Agent shall be entitled to rely upon any certification, notice or other 
communication (including any thereof by telephone, telex, telecopier, 
telegram or cable) believed by it to be genuine and correct and to have been 
signed or given by or on behalf of the proper Person or Persons, and upon 
advice and statements of legal counsel, independent accountants and other 
experts selected by the Agent.  As to any matters not expressly provided for 
by the Loan Instruments, the Agent shall in all cases be fully protected in 
acting, or in refraining from acting, under the Loan Instruments in 
accordance with instructions signed by the Required Banks, and such 
instructions of the Required Banks and any action taken or failure to act 
pursuant thereto shall be binding on all of the Banks.

     SECTION 7.3   DEFAULTS.  The Agent shall not be deemed to have
knowledge of the occurrence of a Default (other than the non-payment to it
of principal of or interest on Loans or fees) unless the Agent has received
notice from a Bank or the Borrower specifying such Default and stating that
such notice is a "Notice of Default."  In the event that the Agent has
knowledge of such a non-payment or receives such a notice of the occurrence
of a Default, the Agent shall give prompt notice thereof to the Banks.  In
the event of any Default, the Agent shall (a) in the case of a Default that
constitutes an Event of Default, take any or all of the actions referred to
in SECTION 6.2 if so directed by the Required Banks and (b) in the case of
any Default, take such other action with respect to such Default as shall
be reasonably directed by the Required Banks.  Unless and until the Agent
shall have received such directions, in the event of any Default, the Agent
may (but shall not be obligated to) take such action, or refrain from
taking such action, with respect to such Default as it shall deem advisable
in the best interests of the Banks.

     SECTION 7.4   RIGHTS AS A BANK.  Each Person acting as the Agent that
is also a Bank shall, in its capacity as a Bank, have the same rights and
powers under the Loan Instruments as any other Bank and may exercise the
same as though it were not acting as the Agent, and the term "Bank" or
"Banks" shall include such Person in its individual capacity.  Each Person
acting as the Agent (whether or not such Person is a Bank) and its
Affiliates may (without having to account therefor to any Bank) accept
deposits from, lend money to and generally engage in any kind of banking,
trust or other business with the Borrower and other parties to the Loan
Instruments and their Affiliates as if it were not acting as the Agent, and
such Person and its Affiliates may accept fees and other consideration from
the Borrower and 

                                    -68-

<PAGE>

other parties to the Loan Instruments and their Affiliates for services in 
connection with the Loan Instruments or otherwise without having to account 
for the same to the Banks.

     SECTION 7.5   INDEMNIFICATION.  The Banks agree to indemnify the
Agent (to the extent not reimbursed by the Borrower and other parties to
the Loan Instruments under the Loan Instruments), ratably on the basis of
the respective principal amounts of the Loans outstanding made by the Banks
(or, if no Loans are at the time outstanding, ratably on the basis of their
respective Commitments), for any and all Liabilities, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements of
any kind and nature whatsoever that may be imposed on, incurred by or
asserted against the Agent (including the costs and expenses that the
Borrower and other parties to the Loan Instruments are obligated to pay
under the Loan Instruments) in any way relating to or arising out of the
Loan Instruments or any other documents contemplated thereby or referred to
therein or the transactions contemplated thereby or the enforcement of any
of the terms thereof or of any such other documents, provided that no Bank
shall be liable for any of the foregoing to the extent they arise from
gross negligence, willful misconduct or knowing violations of law by the
Agent.

     SECTION 7.6   NON-RELIANCE ON AGENT AND OTHER BANKS.  Each Bank
agrees that it has made and will continue to make, independently and
without reliance on the Agent or any other Bank, and based on such
documents and information as it deems appropriate, its own credit analysis
of the Borrower, its own evaluation of the Collateral and its own decision
to enter into the Loan Instruments and to take or refrain from taking any
action in connection therewith.  The Agent shall not be required to keep
itself informed as to the performance or observance by the Borrower or
other parties to the Loan Instruments of the Loan Instruments or any other
document referred to or provided for therein or to inspect the properties
or books of the Borrower or any Subsidiary thereof or the Collateral. 
Except for notices, reports and other documents and information expressly
required to be furnished to the Banks by the Agent under the Loan
Instruments, the Agent shall have no obligation to provide any Bank with
any information concerning the business, status or condition of the
Borrower or any other party to the Loan Instruments or any Subsidiary
thereof, the Loan Instruments or the Collateral that may come into the
possession of the Agent or any of its Affiliates.

     SECTION 7.7   EXECUTION AND AMENDMENT OF LOAN INSTRUMENTS ON BEHALF
OF THE BANKS.  Each Bank hereby authorizes the Agent to 

                                    -69-

<PAGE>

(a) execute and deliver, in the name of and on behalf of such Bank, (i) the 
Security Agreements, the Guaranty Agreements, the Deeds of Trust and the 
Pledge Agreement, (ii) all Uniform Commercial Code financing and continuation 
statements and other documents the filing or recordation of which are, in the 
determination of the Agent, necessary or appropriate to create, perfect or 
maintain the existence or perfected status of the Security Interest, (iii) 
subordination agreements, subordinating the lien of the Banks to the lien of 
Banc One Leasing Corporation with respect to capital equipment leased by the 
Borrower or Guarantors in an aggregate principal amount not to exceed 
$3,000,000 and (iv) any other Loan Instrument requiring execution by or on 
behalf of such Bank, (b) release Collateral from the Security Interest to the 
extent that such Collateral has been disposed of in accordance with SECTION 
5.2(g).  The Agent shall consent to any amendment of any term, covenant, 
agreement or condition of the Security Agreements, the Guaranty Agreements, 
the Deeds of Trust and the Pledge Agreement, or to any waiver of any right 
thereunder, if, but only if, the Agent is directed to do so in writing by the 
Required Banks; PROVIDED, HOWEVER, that (i) the Agent shall not be required 
to consent to any such amendment or waiver that affects its rights or duties 
and (ii) the Agent shall not, unless directed to do so in writing by each 
Bank, (A) consent to any assignment by any Bank of any of its rights or 
obligations under any such agreement or (B) release any Collateral from the 
Security Interest, except as specified in clause (b) above.

     SECTION 7.8   RESIGNATION OF THE AGENT.  The Agent may at any time
give notice of its resignation to the Banks and the Borrower.  Upon receipt
of any such notice of resignation, the Required Banks may, with the consent
of the Borrower which shall not be unreasonably withheld, appoint a
successor Agent.  If no successor Agent shall have been so appointed by the
Required Banks and shall have accepted such appointment within 30 days
after the resigning Agent's giving of notice of resignation, then the
resigning Agent may, on behalf of the Banks and after consultation with the
Borrower, appoint a successor Agent.  Upon the acceptance by any Person of
its appointment as a successor Agent, (a) such Person shall thereupon
succeed to and become vested with all the rights, powers, privileges,
duties and obligations of the resigning Agent and the resigning Agent shall
be discharged from its duties and obligations as Agent under the Loan
Instruments and (b) the resigning Agent shall promptly transfer all
Collateral within its possession or control to the possession or control of
the successor Agent and shall execute and deliver such notices,
instructions and assignments as may be necessary or desirable to transfer
the rights of the Agent with 

                                     -70-

<PAGE>

respect to the Collateral to the successor Agent.  After any resigning 
Agent's resignation as Agent, the provisions of this ARTICLE VII shall 
continue in effect for its benefit in respect of any actions taken or omitted 
to be taken by it while it was acting as the Agent.

                                  ARTICLE VIII

                                  MISCELLANEOUS


     SECTION 8.1   AMENDMENTS; WAIVERS.  Any term, covenant, agreement or
condition of the Loan Instruments may be amended, and any right under the
Loan Instruments may be waived, if, but only if, such amendment or waiver
is in writing and is signed by (a) in the case of an amendment or waiver
with respect to the Loan Instruments referred to in SECTION 7.7(a), the
Agent, (b) in the case of an amendment or waiver with respect to any other
Loan Instrument, the Required Banks and, if the amendment or waiver would
affect the rights and duties of the Agent, by the Agent, and(c) in the case
of an amendment with respect to any Loan Instrument, by the Borrower;
PROVIDED, HOWEVER, that no amendment or waiver shall be effective, unless
in writing and signed by each Bank affected thereby, to the extent it
(i) changes the amount of such Bank's Commitment, (ii) reduces the
principal of or the rate of interest on such Bank's Loans or Note, or any
fees payable to such Bank hereunder, (iii) postpones any date fixed for any
reduction of the Revolving Loan Commitments or any payment of principal of
or interest on such Bank's Loans, Note or any fees payable to such Bank
hereunder, (iv) except as provided in this Agreement or any other Loan
Instrument, releases any Collateral from the Security Interest, or
(v) amends SECTION 2.9, this SECTION 8.1, the definition of "Required
Banks" contained in SECTION 1.1 or any other provision of this Agreement
requiring the consent or other action of all of the Banks.  Unless
otherwise specified in such waiver, a waiver of any right under the Loan
Instruments shall be effective only in the specific instance and for the
specific purpose for which given.  No election not to exercise, failure to
exercise or delay in exercising any right, nor any course of dealing or
performance, shall operate as a waiver of any right of the Agent or any
Bank under the Loan Instruments or Applicable Law, nor shall any single or
partial exercise of any such right preclude any other or further exercise
thereof or the exercise of any other right of the Agent or any Bank under
the Loan Instruments or Applicable Law.

hereafter existing under any Loan Instrument, whether or not the Banks shall 
have made any demand under such Loan Instrument and although such obligations

by the Borrower of the proceeds of any extensions of credit hereunder or the 
past, present or future business activities of the Borrower including, 
without limitation, the fees and disbursements of counsel incurred in 
connection with any such investigation or litigation or other proceedings 
(but excluding any such losses, liabilities, claims, damages or expenses that 
are determined pursuant to a final, non-appealable order of a court of 
competent jurisdiction to have resulted solely from the gross negligence or 
willful misconduct of the Person to be indemnified).

     SECTION 8.13  SHARING OF RECOVERIES.  Each Bank agrees that, if, for any 
reason, including as a result of (a) the exercise of any right of 
counterclaim, set-off, banker's lien or similar right, (b) its claim in any 
applicable bankruptcy, insolvency or other similar law being deemed secured 
by a Debt owed by it to the Borrower and any Guarantor, including a claim 
deemed secured under Section 506 of the Bankruptcy Code, or (c) the 
allocation of payments by the Agent or the Borrower or any Guarantor in a 
manner contrary to the provisions of SECTION 2.9, such Bank shall receive 
payment of a proportion of the aggregate amount due and payable to it 
hereunder as principal of or interest on the Loans or fees that is greater 
than the proportion received by any other Bank in respect of the aggregate of 
such amounts due and payable to such other Bank hereunder, then the Bank 
receiving such proportionately greater payment shall purchase participations 
(which it shall be deemed to have done simultaneously upon the receipt of 
such payment) in the rights of the other Banks hereunder so that all such 
recoveries with respect to such amounts due and payable hereunder (net of 
costs of collection) shall be pro rata; PROVIDED that if all or part of such 
proportionately greater payment received by the purchasing Bank is thereafter 
recovered by or on behalf of the Borrower or any Guarantor from such Bank, 
such purchases shall be rescinded and the purchase prices paid for such 
participations shall be returned to such Bank to the extent of such recovery, 
but without interest (unless the purchasing Bank is required to pay interest 
on the amount recovered to the Person recovering such amount, in which case 
the selling Bank shall be required to pay interest at a like rate).  The 
Borrower expressly consents to the foregoing arrangements and agrees that any 
holder of a participation in any rights hereunder so purchased or acquired 
pursuant to this SECTION 8.13 shall, with respect to such participation, be 
entitled to all of the rights of a Bank under SECTIONS 2.9, 7.4, 7.5 AND 7.7 
(subject to any condition imposed on a Bank hereunder with respect thereto) 
and may exercise any and all rights of set-off with respect to such 
participation as fully as though the Borrower were directly indebted to the 
holder 


                                      -77-
<PAGE>

of such participation for Loans in the amount of such participation.

          (a)  ASSIGNMENTS.

               (i)  The Borrower may not assign any of its rights or 
               obligations under the Loan Instruments without the prior 
               written consent of (A) in the case of the Loan Instruments 
               referred to in SECTION 7.7(a), the Agent and (B) in the case 
               of any of the other Loan Instruments, each Bank, and no 
               assignment of any such obligation shall release such Borrower 
               therefrom unless the Agent and each Bank, as applicable, 
               shall have consented to such release in a writing 
               specifically referring to the obligation from which such 
               Borrower is to be released.
               
               (ii) Each Bank may from time to time assign any or all 
               of its rights and obligations under the Loan Instruments to 
               one or more Persons; PROVIDED that, except in the case of the 
               grant of a security interest to a Federal Reserve Bank (which 
               may be made without condition or restriction), no such 
               assignment shall be effective unless (A) the assignment is 
               consented to by the Borrower (unless an Event of Default 
               exists) and the Agent, such consents not to be unreasonably 
               withheld, (B) in the case of a partial assignment, the 
               assignment shall involve the assignment of not less than 
               $5,000,000 of the assignor Bank's Commitment and there shall 
               at no time be more than three Banks and the assignment is 
               consented to by the Borrower, such consent not to be 
               unreasonably withheld, (C) a Notice of Assignment in the form 
               of EXHIBIT I with respect to the assignment, duly executed by 
               the assignor and the assignee, shall have been given to the 
               Borrower and the Agent, (D) except in the case of an 
               assignment by the Bank that is the Agent, the Agent shall 
               have been paid an assignment fee of $3,500, (E) unless 
               otherwise agreed to by each of the Banks, such assignment is 
               made on or after the earlier of the date that is 90 days 
               following the Effective Date and the date on which the 
               general syndication of the credit facility provided for 
               herein is completed, as specified by the Agent and (F) in 


                                      -78-
<PAGE>

               the case of an assignment of any Revolving Loan, Revolving 
               Loan Commitment, Term Loan, Acquisition Loan or Acquisition 
               Loan Commitment to any assignee, the assignment shall include 
               a PRO RATA portion of all of the Revolving Loans, Revolving 
               Loan Commitments, Term Loan, Acquisition Loans, and 
               Acquisition Loan Commitments of the assignor Bank.  Upon any 
               effective assignment, the assignor shall be released from the 
               obligations so assigned and, in the case of an assignment of 
               all of its Loans and Commitment, shall cease to be a Bank.  
               In the event of any effective assignment by a Bank, the 
               Borrower shall issue new Notes to the assignee Bank (against, 
               other than in the case of a partial assignment, receipt of 
               the existing Note of the assignor Bank).  Nothing in this 
               SECTION 8.14 shall limit the right of any Bank to assign its 
               interest in the Loans and its Notes to a Federal Reserve Bank 
               as collateral security under Regulation A of the Board of 
               Governors of the Federal Reserve System, but no such 
               assignment shall release such Bank from it obligations 
               hereunder.

          (b)  PARTICIPATIONS.  Each Bank may from time to time sell or
          otherwise grant participations in any or all of its rights and
          obligations under the Borrower Loan Instruments.  In the event of
          any such grant by a Bank of a participation, such Bank's
          obligations under the Loan Instruments to the other parties
          thereto shall remain unchanged, such Bank shall remain solely
          responsible for the performance thereof, and the Borrower, the
          Agent and the other Banks may continue to deal solely and
          directly with such Bank in connection with such Bank's rights and
          obligations thereunder.  A Bank may not grant to any holder of a
          participation the right to require such Bank to take or omit to
          take any action under the Loan Instruments, except that a Bank
          may grant to any such holder the right to require such holder's
          consent to (i) reduce the principal of or the rate of interest on
          such Bank's Loans, Note or any fees payable to such Bank
          hereunder, (ii) postpone any date fixed for any  payment of
          principal of or interest on such Bank's Loans, Note or any fees
          payable to such Bank hereunder, (iii) permit any Loan Party to
          assign any of its obligations under the Loan Instruments to any
          other Person or (iv) release any Collateral from the Security
          Interest except as required or 


                                      -79-
<PAGE>

          contemplated by the Loan Instruments.  Each holder of a 
          participation in any rights under the Borrower Loan Instruments, if 
          and to the extent the applicable participation agreement so 
          provides, shall, with respect to such participation, be entitled to 
          all of the rights of a Bank as fully as though it were a Bank under 
          SECTIONS 2.9, 2.11, 8.1 AND 8.7 (subject to any conditions imposed 
          on a Bank hereunder with respect thereto) and may exercise any and 
          all rights of set-off with respect to such participation as fully 
          as though the Borrower were directly indebted to the holder of such 
          participation for Loans in the amount of such participation; 
          PROVIDED, HOWEVER, that no holder of a participation shall be 
          entitled to any amounts that would otherwise be payable to it with 
          respect to its participation under SECTION 2.9 OR 2.11 unless (x) 
          such amounts are payable in respect of Regulatory Changes that are 
          enacted, adopted or issued after the date the applicable 
          participation agreement was executed or (y) such amounts would have 
          been payable to the Bank that granted such participation if such 
          participation had not been granted.

     SECTION 8.15  SURVIVAL OF REPRESENTATIONS AND WARRANTIES.  All 
representations and warranties of the Borrower contained in this Agreement or 
of any of its subsidiaries contained in any other Loan Instrument shall 
survive delivery of the Notes and the making of the Loans.

     SECTION 8.16  TERMINATION OF EXISTING LOAN AGREEMENT. Upon payment in 
full of all of Borrower's and MSE Corporation's obligations under the 
Existing Loan Agreement, the Agent will deliver to the Borrower the 
promissory notes listed in the definition of Existing Loan Agreement in 
SECTION 1.1.

     SECTION 8.17  CONFIDENTIALITY. Each Bank agrees to exercise normal and 
reasonable precautions and to exercise due care to keep confidential all 
information of a confidential nature received by it from the Borrower or any 
of its Affiliates pursuant to any Loan Instrument; PROVIDED, HOWEVER, that 
such information may be disclosed: (i) to directors, officers, employees, 
agents, representatives or outside counsel of such Bank or such Bank's 
Affiliates, (ii) to any auditor, examiner or Governmental Authorities, (iii) 
pursuant to any subpoena or other court order or otherwise as may be required 
by Applicable Law, (iv) to the extent reasonably 


                                      -80-
<PAGE>

required in connection with any litigation or proceeding to which the Agent, 
any Bank or their respective Affiliates may be party, (v) to the extent 
reasonably required in connection with the exercise of any remedy hereunder 
or under any other Loan Instrument, (vi) to any assignee of or participant 
in, or prospective assignee of or participant in, any Bank's Loans or its 
Commitment, or any part thereof, who, in each case, agrees in writing to be 
bound by the terms of this provision, and PROVIDED, FURTHER, that no 
confidentiality obligation shall attach to any information which (a) is or 
becomes publicly known, through no wrongful act on the part of any person who 
shall have received such information, (b) is rightfully received by such 
person from a third party, (c) is independently developed by such person or 
(d) is explicitly approved for release by the Borrower or any of its 
Affiliates.

     SECTION 8.18  SEVERABILITY. Any provision in any Loan Instrument that is 
held to be inoperative, unenforceable or invalid in any jurisdiction shall, 
as to that jurisdiction, be inoperative, unenforceable or invalid without 
affecting the remaining provisions in that jurisdiction or the operation, 
enforceability or validity of that provision in any other jurisdiction, and 
to this end the provisions of all Loan Instruments are declared to be 
severable.

     SECTION 8.19  ENTIRE AGREEMENT, COMMITMENT LETTER SUPERSEDED.  This 
Agreement, together with the other Loan Instruments, embodies the entire 
agreement and understanding among the Borrower, the Banks and the Agent, and 
supersedes all prior or contemporaneous agreements and understandings of such 
Persons, verbal or written, relating to the subject matter hereof and 
thereof.  The Commitment Letter between the Borrower and the Agent dated May 
4, 1998 is superseded by this Agreement and the Loan Instruments. Nothing 
herein shall in any manner effect the validity of the Fee Letter executed in 
connection with the Commitment Letter.

     SECTION 8.20  COUNTERPARTS.  This Agreement and any amendment hereof may 
be executed in several counterparts and by each party on a separate 
counterpart, each of which when executed and delivered shall be an original, 
and all of which together shall constitute one instrument.  In proving the 
Agreement it shall not be necessary to produce or account for more than one 
such counterpart signed by the party against whom enforcement is sought.

                                  ARTICLE II

                              GUARANTY OF PAYMENT

     SECTION 2.1  GUARANTY.  The Guarantor hereby irrevocably, absolutely and 
unconditionally: (a) guarantees the due and punctual payment and performance 
when due, whether at stated maturity, by acceleration or otherwise, of the 
Obligations; and (b) agrees to pay any and all expenses (including reasonable 
attorneys' fees and disbursements) which may be paid or incurred by the Agent 
in enforcing any rights with respect to, or collecting, any or all of the 
Obligations and/or enforcing any rights with respect to, or collecting 
against, the Guarantor under this Guaranty.

     SECTION 2.2  GUARANTY OF PAYMENT AND NOT OF COLLECTION.  This Guaranty 
is a guarantee of payment, and not of collection, and a debt of the Guarantor 
for its own account.  Accordingly, the Agent shall not be obligated or 
required before enforcing this Guaranty against Guarantor: (a) to pursue any 
right or remedy the Agent may have against the Borrower or any other 
guarantor of the Obligations in any court, tribunal or otherwise; (b) to make 
any claim in a liquidation or bankruptcy of the Borrower, or any other 
guarantor of the Obligations; (c) to make demand of the Borrower, or any 
other guarantor of the Obligations; or (d) to enforce or seek to enforce or 
realize upon any Collateral or other security held by the Agent or any other 
party which may secure any of the 


                                       4
<PAGE>

Obligations.  In this connection, the Guarantor hereby waives any right it 
may have to require the Agent to take action against the Borrower or any 
other guarantor of the Obligations.

     SECTION 2.3  CONTINUING GUARANTY.  The Guarantor agrees that:  (a) this 
is an open and continuing guaranty of payment and satisfaction, whether the 
Obligations are now or hereafter existing, acquired or created, and 
irrespective of the fact that from time to time under the terms and 
provisions of the Loan Instruments, monies may be advanced, repaid and 
readvanced and the outstanding balance of the Loans may be zero; and (b) the 
Obligations shall not be deemed to have been otherwise fully paid and 
satisfied so long as the Notes, or any other evidence of indebtedness shall 
have any continuing force or effect.  This Guaranty of payment and 
satisfaction will not be discharged until payment in full of all of the 
Obligations, and the Banks' Commitments under the Credit Agreement have been 
terminated.  No payment or payments made by any other person in payment of 
the Obligations shall be deemed to modify, reduce, release or otherwise 
affect the liability or limitations of the Guarantor hereunder until the 
Obligations are indefeasibly paid in full and the Banks' Commitments under 
the Credit Agreement have been terminated.

     SECTION 2.4  GUARANTY ABSOLUTE, SURVIVAL OF REPRESENTATIONS, ETC.  The 
Guarantor covenants and agrees that all of the representations, warranties, 
covenants and other agreements and obligations of Guarantor under this 
Guaranty and the other Loan Instruments: 

          (a)  shall be absolute and unconditional irrespective of the 
validity, legality, binding effect or enforceability of any of the terms and 
provisions of any of the Loan Instruments; 

          (b)  shall survive the execution and delivery of this Guaranty and 
the other Loan Instruments and the advance, repayment and readvance of any or 
all of the monies to be lent thereunder;

          (c)  shall remain and continue in full force and effect without 
regard to any waiver, modification, extension, renewal, consolidation, 
spreading, amendment or restatement of any other term or provision of any 
Loan Instrument (including without limitation any increase in the 
Obligations), to any full, partial or non-exercise of any of the Agent's 
rights, powers, privileges, remedies and interests under any Loan Instrument, 
against any person or with respect to any Collateral, to any release or 
subordination of all or any part of any Collateral, to any statute of 
limitations or similar time constraint under any applicable law, to any 
investigation, analysis or evaluation by the Agent or its designees of the 
assets, business, operations, properties or condition (financial or 
otherwise) of the Guarantor, the Borrower or any other person, to any act or 
omission on the part of the Agent or any other person, or to any other event 
that otherwise might constitute a legal or equitable counterclaim, defense or 
discharge of a surety or guarantor; 


                                       5
<PAGE>

          (d)  shall not be subject to any defense, counterclaim, set-off, 
right of recoupment, abatement, reduction or other claim or determination 
that the Guarantor or the Borrower may have against the Agent, the Banks, or 
any other person;
 
          (e)  shall not be diminished or qualified by the death, disability, 
dissolution, reorganization, insolvency, bankruptcy, custodianship or 
receivership of the Guarantor, the Borrower or any other guarantor, surety or 
pledgor or any other person, or the inability of any of them to pay their 
debts or perform or otherwise satisfy their obligations as they become due 
for any reason whatsoever; and

          (f)  shall remain and continue in full force and effect regardless 
of any other circumstance which might otherwise constitute a defense 
available to, or a discharge of, the Guarantor; it being agreed that the 
obligations of the Guarantor under this Guaranty shall not be satisfied or 
discharged except as expressly provided in this Guaranty.


                                 ARTICLE III

                             CONSENTS AND WAIVERS

     SECTION 3.1  CONSENT.  Without limiting the generality of the foregoing 
Sections or any other term or provision of this Guaranty, the Guarantor  
agrees and consents that, without notice to the Guarantor, at any time, and 
from time to time:

          (a)  the amount of the Loans, the rates of interest thereon or any 
other Obligations may be increased or otherwise changed;

          (b)  the time, manner, place and other terms and provisions of 
payment or performance of the Obligations may be extended, modified, amended,

          (c)  any partial or late payment or any payment during the 
continuance of any default under the Loan Instruments may be accepted in 
whole or in part or rejected;

          (d)  any Collateral securing or intended to secure any obligations 
under any Loan Instrument may be sold, conveyed, assigned or otherwise 
realized upon, dealt with or disposed of in whole or in part;

          (e)  any mortgage or other security interest in any such Collateral 
may be held without due recordation or other perfection (whether 
intentionally or otherwise), may be recorded or otherwise perfected, or may 
be assigned, released, subordinated or otherwise impaired, dealt with or 
disposed of in whole or in part;


                                       6
<PAGE>

          (f)  any one or more payments, distributions and proceeds received 
from or in respect of the Guarantor, the Borrower, any other guarantor, 
surety or pledgor or any other person or any such Collateral may be applied 
to any of the Obligations, or if not designated therefore, or otherwise 
restricted thereto, may be applied to other indebtedness of the Guarantor, 
the Borrower, or any such other guarantor, surety, pledgor or other person 
owed to the Agent or any of its affiliates;

          (g)  the liability of the Guarantor, the Borrower, any other 
guarantor, surety or pledgor or any other person to pay any and all of the 
Obligations may be settled, or compromised or released, in whole or in part;

          (h)  the rights of set-off of the Agent may be exercised as 
provided under this Guaranty, any other Loan Instrument or applicable law 
against any of the deposits, assets, properties and indebtedness subject 
thereto, without any demand on or notice to the Guarantor or the Borrower, 
without regard to the frequency of exercise thereof, and whether or not the 
relevant Obligations shall then be matured;

          (i)  any representation, warranty, covenant or other term or 
provision of any Loan Instrument, or any part thereof, may be a subject of 
one or more waivers of applicability or consents to nonperformance, 
noncompliance or nonobservance, whether or not constituting defaults, or may 
be otherwise not exercised or enforced (whether intentionally or otherwise);

          (j)  any one or more of this Guaranty, the Notes and any other Loan 
Instrument, or any one or more of the rights, powers, privileges, remedies 
and interests of the Agent herein or therein, may be sold, conveyed, assigned 
or otherwise transferred in whole or part (including participations or other 
undivided interests) to any other person; and/or

          (k)  any other right, power, privilege, remedy or interest of the 
Agent under the Guaranty, the Notes, any other Loan Instrument or applicable 
law may be exercised or enforced by the Agent or its designee, which exercise 
or enforcement may be delayed, discontinued or otherwise not pursued or 
exhausted for any or no reason whatsoever, or any such right, power, 
privilege, remedy or interest may be waived, omitted or otherwise not 
exercised or enforced (whether intentionally or otherwise), in the sole and 
absolute discretion of the Agent.

     SECTION 3.2  WAIVER.  The Guarantor, to the fullest extent permitted by 
law, hereby irrevocably waives each of the following:

          (a)  any duty on the part of the Agent to disclose to the Guarantor 
any matter, fact or thing relating to the business, operation or condition of 
the Borrower, or its assets now known or hereafter known by the Agent;


                                       7
<PAGE>

          (b)  any and all notice of:  (i) acceptance of this Guaranty; (ii) 
any action taken or omitted in reliance hereon; and (iii) any default in the 
payment of any sums due pursuant to the Obligations, or any Loan Instrument 
or otherwise;

          (c)  presentment, demand for payment, protest or notice of protest 
relating to this Guaranty, the Obligations and/or any of the Loan Instruments;

          (d)  any and all notice of the occurrence or continuance of any 
Default, Event of Default or any event that (with the giving of notice or the 
passage of time or both) could constitute a Default, under any of the Loan 
Instruments, or of any other material or adverse event or Material Adverse 
Effect;

          (e)  any and all notice of the terms, time, and place of any public 
or private sale of any of the Collateral whether required by the Code or 
otherwise;

          (f)  any "one action" or anti-deficiency law or any other law which 
may prevent the Agent from bringing any action, including a claim for 
deficiency, against the Guarantor, before or after the Agent's commencement 
or completion of any foreclosure action, either judicially or by exercise of 
a power of sale;

          (g)  any election of remedies by the Agent which destroys or 
otherwise adversely affects the Guarantor's subrogation rights or the 
Guarantor's rights to proceed against the Borrower for reimbursement, 
including without limitation, any loss of right the Guarantor may suffer by 
reason of any law limiting, qualifying, or discharging the Obligations;

          (h)  any disability or other defense of the Borrower or any other 
guarantor, or of any other person, or by reason of the cessation of the 
liability of the Borrower from any cause whatsoever, other than payment in 
full in legal tender, of the Obligations;

          (i)  any right to claim discharge of the Obligations on the basis 
of unjustified impairment of any Collateral;

          (j)  any statute of limitations, if at any time any action or suit 
brought by the Agent against the Guarantor is commenced there is outstanding 
any of the Obligations which are not barred by any applicable statute of 
limitations;

          (k)  any defenses given to guarantors at law or in equity other 
than actual payment and performance of the Obligations including all 
defenses based upon suretyship or impairment of collateral pursuant to C.R.S.
Section 4-3-603;


                                       8
<PAGE>

          (l)  any and all right, if any, to require the Agent to:  (i) 
continue lending money or to extend other credit to the Borrower; (ii) 
proceed directly against, marshall or exhaust any of the Collateral; (iii) 
pursue any remedy within the Agent's power; or (iv) commit any act or 
omission of any kind, at any time, with respect to any matter whatsoever; and

          (m)  any other proof, notice or demand of any kind whatsoever with 
respect to any or all of the Obligations or promptness in making any claim or 
demand under this Guaranty or any of the Loan Instruments.  No act or 
omission of any kind in connection with any of the foregoing shall in any way 
impair or otherwise affect the legality, validity, binding effect or 
enforceability of any term or provision of this Guaranty or any of the 
obligations of the Guarantor hereunder.

     SECTION 3.3  WAIVER OF SUBROGATION.  The Guarantor hereby irrevocably 
waives any and all claims and other rights that it now has or may hereafter 
acquire against the Borrower, or any other guarantor, that arise from the 
existence, payment, performance or enforcement of this Guaranty or any other 
Loan Instruments, including any right of subrogation, reimbursement, 
exoneration, contribution or indemnification and any right to participate in 
any claim or remedy of the Agent against the Borrower, any other guarantor or 
any Collateral that the Guarantor now has or hereafter acquires, whether or 
not such claim, remedy or right arises in equity or under contract, statute 
or common law, including the right to take or receive from the Borrower, 
directly or indirectly, in cash or other property, by set-off or in any other 
manner, payment or security on account of any such claim or other right.  If 
any amount is paid to the Guarantor in violation of the preceding sentence 
and the Obligations have not been paid in full, such amounts shall be deemed 
to have been paid to the Guarantor for the benefit of, and held in trust for 
the benefit of, the Agent and shall be forthwith paid to the Agent to be 
credited and applied to the Obligations, whether matured or unmatured, in 
accordance with the terms of the Loan Instruments.  This waiver of 
subrogation is for the benefit of the Agent and the foregoing waiver may not 
be revoked by the Guarantor without the prior written consent of the Agent.

     SECTION 3.4  ACKNOWLEDGMENT OF BENEFIT.  The Guarantor acknowledges that 
it has received and will receive direct and indirect benefits from the 
financing arrangements contemplated by the Loan Instruments and that the 
consents and waivers set forth in this Article are knowingly made in 
contemplation of such benefits.  

     SECTION 3.5  MISCELLANEOUS.  The Guarantor understands and agrees that 
the foregoing waivers and the other waivers, consents, releases and 
agreements contained in this Guaranty will, among other things, adversely and 
materially effect, and under certain circumstances may eliminate entirely, 
the Guarantor's rights or ability to collect monies from the Borrower that 
the Guarantor may have paid to the Borrower and defenses that the Guarantor 
might have to payment of the Obligations.  This result may occur because of 
the actions of the Agent or the Borrower, such as electing certain remedies 
and foregoing or delaying others, releasing security, or modifying the 
Obligations, all without notice to or consent from the Guarantor.  The 
Guarantor agrees that the foregoing waivers 


                                       9
<PAGE>

and the other waivers, consents, releases and agreements contained in this 
Guaranty are made with the Guarantor's full knowledge of their significance 
and consequences and that, under the circumstances, the waivers are 
reasonable and not contrary to public policy or law.  If any such waiver is 
determined to be contrary to any applicable law or public policy, such waiver 
shall be effective only to the extent permitted by law or public policy.


                                   ARTICLE IV

                          SUBORDINATION OF INDEBTEDNESS

     SECTION 4.1  SUBORDINATION OF INDEBTEDNESS.  The Guarantor covenants and 
agrees that until all of the Obligations have been fully paid and satisfied, 
all indebtedness of the Borrower together with interest thereon, owed 
directly or indirectly to the Guarantor, whether now or hereafter existing, 
acquired or created, whether as a result of any payment made by the Guarantor 
or otherwise, shall be subordinate, junior and inferior in dignity and 
deferred as to payment to the full payment and satisfaction of all of the 
Obligations.  The Guarantor shall not seek any payment or exercise or enforce 
any right, power, privilege, remedy or interest that it may have with respect 
to any such indebtedness except with the prior written consent of the Agent 
and except in connection with a bankruptcy of the Borrower, in which case the 
Guarantor may file any claims it may have against the Borrower, subject to 
the provisions of Section 4.3 below to pay over any amounts received to the 
Agent.  Any payment, asset or property delivered to or for the benefit of the 
Guarantor in respect of any such indebtedness shall be accepted in trust for 
the benefit of the Agent and shall be promptly paid or delivered to the Agent 
to be credited and applied to the payment and satisfaction of the 
Obligations, whether matured or unmatured, or to be held by the Agent as 
additional Collateral.  The Guarantor agrees to execute such additional 
documents as the Agent may reasonably request to evidence the subordination 
provided in this Section.

     SECTION 4.2  SECURITY INTEREST IN INDEBTEDNESS.  The Guarantor hereby 
assigns and grants to the Agent a continuing security interest in and to all 
indebtedness owing from the Borrower to the Guarantor, whether or not 
hereafter existing, acquired or created, together with the proceeds thereof, 
all payments and other distributions with respect thereto and any and all 
renewals, substitutions, modifications and extensions of any and all of the 
foregoing, as security for the timely and full payment and satisfaction of 
the Obligations as and when due.  The Guarantor shall endorse and deliver to 
the Agent such instruments representing that indebtedness and shall execute 
and deliver to the Agent such financing statements and other documents as the 
Agent may deem necessary or desirable to evidence, confirm or perfect the 
foregoing security interest (which financing statements may be signed by the 
Agent on behalf and in the name of  the Guarantor if the Guarantor does not 
promptly sign and return the same).  In addition to the rights, powers, 
privileges, remedies and interest afforded to the Agent by this Guaranty and 
applicable law, if an Event of Default has occurred, the Agent may exercise 
any voting, consent, enforcement or other right, power, privilege, 


                                      10
<PAGE>

remedy or interest pertaining to any item of such collateral to the same 
extent as if the Agent were the outright owner thereof. The Agent is hereby 
authorized, in the name of the Guarantor, from time to time to execute and 
file financing statements and continuation statements and to execute such 
other documents and to take such other actions as the Agent deems necessary 
or appropriate to perfect, preserve and enforce its rights under this 
Guaranty.

     SECTION 4.3  BANKRUPTCY.  In the event of insolvency, reorganization, or 
liquidation of the assets of the Borrower through bankruptcy, by an 
assignment for the benefit of creditors, by voluntary liquidation, or 
otherwise, the assets of the Borrower applicable to the payment of the claims 
of both the Agent and the Guarantor shall be paid to the Agent and shall, 
subject to Applicable Law, be applied by the Agent to the Obligations in such 
order and manner as the Agent may determine.  The Guarantor does hereby 
assign to the Agent all claims which it may have or acquire against the 
Borrower or against any assignee or trustee in bankruptcy of the Borrower; 
provided, however, that such assignment shall be effective only for the 
purpose of assuring to the Agent full payment in legal tender of all 
Obligations.


                                  ARTICLE V

                               RIGHT OF SET-OFF

     SECTION 5.1  RIGHT OF SET-OFF, ETC.  Upon the occurrence and during the 
continuance of any Event of Default, the Agent hereby is authorized at any 
time and from time to time, without notice to the Guarantor (any such notice 
being hereby expressly waived by the Guarantor), to set-off and apply, 
directly or through any of its affiliates, custodians, participants and 
designees, any and all deposits (whether general or special, time or demand, 
provisional or final, or individual or joint) and other assets and properties 
at any time held in the possession, custody or control of the Agent and any 
of its affiliates, custodians, participants and designees, and any 
indebtedness or other amount at any time held in the possession, custody or 
control of the Agent and any of its affiliates, custodians, participants and 
designees, and any indebtedness or other amount at any time owing by the 
Agent or any of its affiliates or participants, to or for the credit, account 
or benefit of the Guarantor against any and all of the Obligations now or 
hereafter existing under this Guaranty, whether or not the Agent shall have 
declared a Default, accelerated the Obligations or made any demand or taken 
any other action under this Guaranty, and although such Obligations may be 
unmatured.  The Guarantor hereby grants to the Agent a security interest in 
and to, among other things, all such deposits, assets, properties and 
indebtedness in the possession of the Agent's affiliates, custodians, 
participants and designees, and the Guarantor hereby authorizes any such 
person to so set-off and apply such amounts at such times and in such manner 
as the Agent may direct pursuant to this Section.  The Agent shall notify the 
Guarantor subject to such set-off after any such set-off and application; 
provided, however, that the failure to give such notice shall not affect the 
validity of such set-off and application.  In debiting any such account, the 
Obligations shall be 


                                      11
<PAGE>

deemed to have been paid or repaid only to the extent of the funds actually 
available in the account notwithstanding any internal procedure of the Agent 
or any of its affiliates, custodians, participants and designees to the 
contrary.  The rights of the Agent under this Section are in addition to and 
without limitation of any other rights, powers, privileges, remedies and 
other interests (including, without limitation, other rights of set-off and 
security interests) that the Agent may have under this Guaranty and 
applicable law.


                                  ARTICLE VI

                           REPRESENTATIONS, WARRANTIES,
                             AGREEMENTS AND COVENANTS

     SECTION 6.1  GENERAL REPRESENTATIONS, WARRANTIES AND AGREEMENTS.  So 
long as any of the Obligations remain outstanding, the Guarantor hereby 
represents and warrants to, and agrees with, the Agent that:

          (a)  LEGAL CAPACITY.  The Guarantor has the legal capacity and 
power to execute and deliver this Guaranty.

          (b)  VALID AND BINDING.  This Guaranty, when executed and delivered 
by the Guarantor, will be a legal, valid and binding obligation of the 
Guarantor enforceable in accordance with the terms and provisions of this 
Guaranty, except as enforceability may be limited by applicable bankruptcy, 
insolvency or Applicable Laws affecting the enforcement and creditors' rights 
generally or by equitable principles relating to enforceability.

          (c)  NO VIOLATION OF LAW OR CONTRACT.  The execution and delivery 
of this Guaranty and the performance by the Guarantor of the obligations 
hereunder: (i) will not violate or be in conflict with (A) any provision of 
applicable law, or (B) any judgment, order, writ, injunction, decree or 
consent of any court or other judicial authority, and (ii) will not violate, 
be in conflict with, result in a breach of or constitute a default under, any 
material instrument, indenture, agreement or obligation of the Guarantor.

          (d)  NO OTHER CONDITIONS PRECEDENT.  There are no conditions 
precedent to the effectiveness of this Guaranty that have not been satisfied 
or waived.

          (e)  INDEPENDENT INVESTIGATION.  The Guarantor has, independently 
and without reliance upon the Agent and based on documents and information as 
it has deemed appropriate, made its own credit analysis and decision to enter 
into this Guaranty.


                                      12
<PAGE>

          (f)  FINANCIAL STATEMENTS. The audited consolidated balance sheets 
of the Borrower and the Guarantors (for purposes of this Section 6.1(f), as 
"Guarantors" is defined in the Credit Agreement) at March 31, 1998, and the 
related consolidated statements of income and retained earnings of the 
Borrower and the Guarantors for the fiscal year then ended, and the related 
consolidated statements of income and retained earnings of the Borrower and 
Guarantors for the fiscal year ended March 31, 1998, copies of which have 
been furnished to the Banks, fairly present the financial condition of the 
Borrower and the Guarantors as at such date and the results of the operations 
of the Borrower and the Guarantors for the period ended on such date, all in 
accordance with Regulation S-X promulgated under the Securities Exchange Act 
of 1934, and since March 31, 1998, there has been no material adverse change 
in such condition or operations except as disclosed in SCHEDULE 4.1(f) of the 
Credit Agreement.

          (g)  LITIGATION.  Except as set forth in SCHEDULE 4.1(g) of the 
Credit Agreement, the Guarantor represents and warrants that there is no 
pending, or to the Guarantor's knowledge, threatened action or proceeding 
affecting the Guarantor or its properties or business activities, before any 
court, governmental agency or arbitrator, in which there is a reasonable 
possibility of a Material Adverse Effect or which purports to affect the 
legality, validity or enforceability of this Agreement or any Loan Instrument 
to which the Guarantor will be a party.

          (h)  SOLVENCY.   As of the date hereof, after giving effect to the 
direct and indirect indebtedness and other liabilities of the Guarantor 
arising under this Guaranty, the Guarantor:  (i) is solvent (I.E., the 
aggregate fair value of its assets exceeds the sum of its liabilities); (ii) 
has adequate capital; and (iii) is able to pay its debts as they mature.  Any 
term or provision of this Guaranty to the contrary notwithstanding, the 
aggregate amount of the Obligations guaranteed hereunder shall be reduced to 
the minimum extent necessary to prevent this Guaranty from violating or 
becoming voidable under applicable law relating to fraudulent conveyance or 
fraudulent transfer or similar laws affecting the rights of creditors 
generally.

          (i)  REVIEW OF CREDIT AGREEMENTS.  The Guarantor has reviewed and 
understands the Credit Agreement.

          (j)  NO MATERIAL MISREPRESENTATIONS OF OMISSIONS.  No 
representation, warranty, agreement or covenant of the Guarantor made or 
contained in this Guaranty and no report, statement, certificate, schedule or 
other document or information furnished by the Guarantor in connection with 
the transactions contemplated by this Guaranty contains or will contain a 
misstatement of a material fact or omits or will omit to state a material 
fact required to be stated therein in order to make it, in the light of the 
circumstances under which made, not misleading in any material respect as of 
the date made or deemed made.

     SECTION 6.2  AFFIRMATIVE COVENANTS.  So long as any of the Obligations 
remain outstanding, the Guarantor hereby covenants and agrees that, unless 
the Agent shall consent otherwise in writing:

          (a)  NOTICE OF CERTAIN CHANGES.  Upon receipt of knowledge thereof, 
the Guarantor shall give, or cause to be given, immediate written notice to

otherwise be restored or returned by the Agent upon the insolvency,

have any duty to advise the Guarantor of information known to it or any Bank 
regarding such circumstances or risks.

     SECTION 8.6  FURTHER ASSURANCES.  The Guarantor agrees to do such

and correct and to have been signed, sent or made by the proper person or 
persons, and upon opinions and advice of legal counsel (including counsel for 
the Guarantor), independent public accountants and other experts selected by 
the Agent.  The Agent shall be entitled to rely, and in entering into this

any part of the assets, business, operations, properties or condition 
(financial or otherwise) of the Guarantor.

     SECTION 8.8  EXCULPATION.  The Agent, the Banks and their designees, and 
their respective directors, officers, employees, attorneys and agents, shall 
not incur any liability (other than for a person's own acts or omissions

willful misconduct as finally determined pursuant to applicable law by a 
governmental authority having jurisdiction) for acts and omissions arising 
out of or related directly or indirectly to this Guaranty or any of the Loan 
Instruments; and the Guarantor hereby expressly waives any and all claims and 
actions (other than those attributable to a person's own acts or omissions 
breaching a duty owed to a Guarantor and amounting to gross negligence or 
willful misconduct as finally determined pursuant to applicable law by a 
governmental authority having jurisdiction) against the Agent, the Banks and 
their designees, and their respective directors, officers, employees, 
attorneys and agents, arising out of or related directly or indirectly to any 
and all of the foregoing acts, omissions and circumstances.

     SECTION 8.9  INDEMNIFICATION.  The Agent, the Banks and their designees, 
and their respective directors, officers, employees, attorneys and agents, 
shall be indemnified, reimbursed, held harmless and, at the request of the 
Agent, defended by the Guarantor from and against any and all claims, 
liabilities, losses and expenses (including, without limitation, the 
reasonable disbursements, expenses and fees of their respective attorneys) 
that may be imposed upon, incurred by, or asserted against any of them, or 
any of their respective directors, officers, employees, attorneys and agents, 
arising out of or related directly or indirectly to this Guaranty or any of 
the Loan Instruments, except such as are occasioned by the indemnified 
person's own acts or omissions breaching a duty owed to a Guarantor or 
amounting to gross negligence or willful misconduct as finally determined 
pursuant to applicable law by a governmental authority having jurisdiction.

     SECTION 8.10  INTERPRETATION.  The parties acknowledge and agree that: 
each party and its counsel have reviewed and negotiated the terms and 
provisions of this Guaranty and have contributed to its revision; the normal 
rule of construction, to the effect that any ambiguities are resolved against 
the drafting party, shall not be employed in the interpretation of it; and 
its terms and provisions shall be construed fairly to all parties hereto and 
not in favor of or against any party, regardless of which party was generally 
responsible for the preparation of this Guaranty.

     SECTION 8.11  WAIVER AND MODIFICATION.  This Guaranty constitutes the 
entire agreement and understanding of the parties as to matters set forth in 
this Guaranty.  This Guaranty and the provisions hereof may be waived, 
amended, modified, changed, discharged or terminated only by an instrument in 
writing and signed by the Guarantor and the Agent.  No delay or omission on 
the part of the Agent in exercising any right under this Guaranty shall 
operate as a waiver of such right or any other right.  A waiver by the Agent 
of a provision of this Guaranty shall not prejudice or constitute a waiver of 
the Agent's right otherwise to demand strict compliance with that provision 
or any other provision of this Guaranty.  No prior waiver by the Agent, nor 
any course of dealing between the Agent and the Guarantor, shall constitute a 
waiver of any of the Agent's rights or any of the Guarantor's obligations as 
to any future transactions.  Whenever the consent of the Agent is 

                                      18

<PAGE>

required under this Guaranty, the granting of such consent by the Agent in 
any instance shall not constitute continuing consent to subsequent instances 
where such consent is required and, unless otherwise provided herein, such 
consent may be granted or withheld in the sole and absolute discretion of the 
Agent.

     SECTION 8.12  BINDING AGREEMENT.  This Guaranty shall be binding upon

delegate its duties hereunder without the Agent's prior written consent. 
However, the Agent may assign or otherwise transfer any rights under this

such other person or entity shall thereupon become vested with all the 
benefits in respect thereof granted to the Agent herein or otherwise.

            (ii)   Pledgor has full power and lawful authority to enter into
     this Pledge and Security Agreement and to pledge, assign and transfer the
     Pledged Collateral to Agent and to grant to Agent a first and prior
     security interest therein as herein provided, all of which have been duly
     authorized by all necessary corporate action;

            (iii)  the execution and delivery and the performance hereof are not
     in contravention of any charter, article of incorporation or by-law
     provision, or of any indenture, agreement or undertaking to which Pledgor
     is a party or by which Pledgor or its property is bound;

            (iv)   this Pledge and Security Agreement constitutes the valid and
     legally binding obligation of Pledgor enforceable in accordance with its
     terms, subject, as to enforcement, to bankruptcy, insolvency,
     reorganization, moratorium and other laws of general applicability relating
     to or affecting creditors' rights and to general equity principles; and

            (v)    Pledgor will defend the Pledged Collateral against all claims
     and demands of all persons at any time claiming the same or any interest
     therein.  Any officer, agent or representative acting for or on behalf of
     Pledgor in connection with this Pledge and Security Agreement or any aspect
     hereof, or entering into or executing this Pledge and Security Agreement on
     behalf of Pledgor, has been duly authorized to do so, and is fully
     empowered to act for and represent Pledgor in connection with this Pledge
     and Security Agreement and all matters related thereto or in connection
     therewith.

     (c) (i)  Pledgor has not heretofore signed any financing statement or 
security agreement which covers any of the Pledged Collateral, and no such 
financing statement or security agreement is now on file in any public office.

             (ii)  As long as any amount remains unpaid on any of the
     Obligations or under any agreements entered into in connection with the
     Obligations, except as expressly permitted by any such agreements,
     (A) Pledgor will not enter into or execute any security agreement or
     financing statement covering the Pledged Collateral, other than those
     security agreements and financing statements in favor of Agent hereunder,
     and further (B) there will not be on file in any public office any
     financing statement or statements (or any documents or papers filed as
     such) covering the Pledged Collateral, other than financing statements in
     favor of Agent hereunder, unless in any case the prior written consent of
     Agent shall have been obtained.

            (iii)  At the request of Agent, Pledgor will join Agent in
     executing such documents as Agent may determine from time to time to be
     necessary or desirable under provisions of any applicable laws in effect
     where the Pledged Collateral is 


                                       -3-

<PAGE>

     located or where Pledgor conducts business; without limiting the 
     generality of the foregoing, Pledgor agrees to join Agent, at Agent's 
     request, in executing one or more financing statements or other 
     instruments in form satisfactory to Agent, and Pledgor will pay the 
     costs of filing or recording the same, or of filing or recording this 
     Pledge Agreement, in all public offices at any time and from time to 
     time whenever filing or recording of any such financing statement or of 
     this Pledge Agreement is deemed by Agent to be necessary or desirable.  
     In connection with the foregoing, it is agreed and understood between 
     the parties hereto (and Agent is hereby authorized to carry out and 
     implement this agreement and understandings, and Pledgor hereby agrees 
     to pay the costs thereof) that Agent may, at any time or times, file as 
     a financing statement any counterpart, copy or reproduction of this 
     Pledge Agreement.

     (d) In the event that Pledgor receives any promissory notes or 
evidences of indebtedness of any Subsidiary Issuer, Pledgor shall hold the 
same in trust as property of the Banks and forthwith assign, pledge and 
deliver the same to Agent for the ratable benefit of the Banks.

     5.  RIGHTS OF AGENT AND PLEDGOR RELATED TO PLEDGED COLLATERAL.

     Agent may from time to time following the occurrence of an Event of 
Default, as defined in SECTION 7 hereof:

     (a) Transfer any of the Pledged Collateral into the name of Agent or 
its nominee.

     (b) Notify parties obligated on any of the Pledged Collateral to make 
payment to Agent of any amounts due or to become due thereunder.

     (c) Enforce collection of any of the Pledged Collateral by suit or 
otherwise; surrender, release or exchange all or any part thereof, or 
compromise or extend or renew for any period (whether or not longer than the 
original period) any obligation of any nature of any party with respect 
thereto; and exercise all other rights of Pledgor in any of the Pledged 
Collateral, except as hereinafter provided with respect to income from or 
interest on the Pledged Collateral and except that, prior to an Event of 
Default, Pledgor may exercise its voting and consensual rights with respect 
to any Pledged Collateral constituting voting securities.

     (d) Take possession or control of any proceeds of the Pledged 
Collateral.

     Until the occurrence of an Event of Default, Pledgor shall have the 
right to receive all income from or interest on the Pledged Collateral, and 
if Agent receives any such income or interest prior to the occurrence of an 
Event of Default, Agent shall pay the same promptly to Pledgor, except that 
in the case of securities or other property distributed by way of a dividend 
or otherwise with respect to the Pledged Collateral, such securities or other 
property (other than cash) shall be promptly delivered to Agent to be held as 
Pledged Stock or other Pledged Collateral hereunder.  Upon the occurrence of 
an Event of Default, Pledgor will not demand or receive any income from or 
interest on the Pledged Collateral, and if Pledgor receives any such income 
or interest without any demand by it, the same shall be held by Pledgor in 
trust for Agent in the same medium in which received, shall not be commingled 
with any assets of Pledgor and shall be delivered to Agent in the 


                                       -4-

<PAGE>

form received, properly endorsed to permit collection, not later than the 
next business day following the day of its receipt.  Agent shall promptly 
apply the net cash received from such income or interest to payment of any of 
the Obligations, provided that Agent shall account for and pay over to 
Pledgor any such income or interest remaining after payment in full of the 
Obligations then outstanding.

     So long as no Event of Default or event which, with the giving of notice 
or the lapse of time, or both, would become an Event of Default shall have 
occurred and be continuing:

          (i)   Pledgor shall be entitled to exercise any and all voting and
     other consensual rights pertaining to the Pledged Collateral or any part
     thereof for any purpose not inconsistent with the terms of this Pledge
     Agreement or the Credit Agreement; PROVIDED, HOWEVER, that Pledgor shall
     not exercise or refrain from exercising any such right if, in Agent's
     judgment, such action would have a material adverse effect on the value of
     the Pledged Collateral or any part thereof; and, PROVIDED, FURTHER, that
     upon the request of Agent, Pledgor shall give Agent at least five days'
     written notice of the manner in which it intends to exercise, or the
     reasons for refraining from exercising, any such rights; and

          (ii)  Agent shall execute and deliver (or cause to be executed and
     delivered) to Pledgor all such proxies and other instruments as Pledgor may
     reasonably request for the purpose of enabling Pledgor to exercise the
     voting and other rights which it is entitled to exercise pursuant to
     PARAGRAPH (i) above.

     Agent shall never be under any obligation to collect, attempt to 
collect, protect or enforce the Pledged Collateral or any security therefor, 
which Pledgor agrees and undertakes to do at Pledgor's expense, but Agent may 
do so in its discretion at any time after the occurrence of an Event of 
Default and at such time Agent shall have the right to take any steps by 
judicial process or otherwise as it may deem proper to effect the collection 
of all or any portion of the Pledged Collateral or to protect or to enforce 
the Pledged Collateral or any security therefor.  All reasonable expenses 
(including, without limitation, reasonable attorneys' fees and expenses) 
incurred or paid by Agent in connection with any such collection or attempt 
to collect the Pledged Collateral or actions to protect or enforce the 
Pledged Collateral or any security therefor shall be borne by Pledgor or 
reimbursed by Pledgor to Agent upon demand.  The proceeds received by Agent 
as a result of any such actions in collecting or enforcing or protecting the 
Pledged Collateral shall be held by Agent without liability for interest 
thereon and shall be promptly applied by Agent as Agent may deem appropriate 
toward payment of any of the Obligations secured hereby in such order or 
manner as Agent may elect.

     In the event Agent shall pay any taxes, assessments, interests, costs, 
penalties or expenses incident to or in connection with the collection of the 
Pledged Collateral or protection or enforcement of the Pledged Collateral or 
any security therefor, Pledgor, upon demand of Agent, shall pay to Agent the 
full amount thereof with interest at a rate per annum (based on a 360-day 
year for the actual number of days involved) from the date expended by Agent 
until repaid equal to the sum of three percent (3%) plus the Prime Rate in 
effect under and defined by the Credit Agreement.  So long as Agent shall be 
entitled to any such payment, this Pledge Agreement shall operate as security 
therefor as fully and to the same extent as it operates as security for 
payment of the other Obligations 


                                       -5-

<PAGE>

secured hereunder, and for the enforcement of such repayment, Agent shall 
have every right and remedy provided hereunder for enforcement of payment of 
the Obligations.

     6.  FURTHER ASSURANCES; AGENT AS AGENT.

     Pledgor agrees to take such actions and to execute such stock or bond 
powers and such other or different writings as Agent may request (and 
irrevocably authorizes Agent to execute such writings as Pledgor's agent and 
attorney-in-fact) further to perfect, confirm and assure Agent's security 
interest in the Pledged Collateral and to assist Agent's realization thereon 
including, without limitation, the right to receive, indorse, and collect all 
instruments made payable to Pledgor representing any dividend, interest 
payment or other distribution in respect of the Pledged Collateral or any 
part thereof except to the extent Pledgor is entitled to receive any cash 
dividend pursuant to Section 5.

     7.  EVENT OF DEFAULT.

     The occurrence of any of the following shall constitute an "Event of 
Default" hereunder:

     (a) Failure of Pledgor to pay any Obligation (including any installment 
of principal or interest thereon) when due and payable (after the expiration 
of any grace period provided by the applicable Loan Instruments), whether at 
maturity, by notice of intention to prepay or otherwise;

     (b) Default in the timely performance by Pledgor of any obligation or 
covenant contained herein or an Event of Default under the Credit Agreement 
or any other Collateral Document to which Pledgor is a party, which default 
shall not have been cured during any applicable grace period;

     (c) Any representation or warranty made by Pledgor herein or in any 
other agreement with or instrument delivered to Agent, or any statement or 
representation made in any certificate, report or opinion delivered in 
connection herewith or in connection with any such other agreement or 
instrument that proves to be false or misleading in any material respect when 
made; or

     (d) The insolvency of Pledgor, the admission by Pledgor of its 
inability to pay its debts as they become due, the commencement of any case 
by or against Pledgor under any bankruptcy or insolvency law (and, in the 
event such case is not instituted by Pledgor, it shall remain undismissed or 
unstayed for a period of 45 days or any of the actions sought in such 
proceeding shall occur), or the making by Pledgor of any assignment for the 
benefit of creditors.

     8.  RIGHTS AND REMEDIES OF AGENT UPON DEFAULT.

     If an Event of Default shall have occurred:


                                       -6-

<PAGE>

     (a)  Agent shall have and may exercise with reference to the Pledged 
Collateral and the Obligations any or all of the rights and remedies of a 
secured party under the Uniform Commercial Code ("UCC"), as applicable, and 
as otherwise granted herein or under any other applicable law or under any 
other agreement now or hereafter in effect executed by Pledgor, including, 
without limitation, the right and power to sell, at public or private sale or 
sales, or otherwise dispose of, or otherwise utilize the Pledged Collateral 
and any part or parts thereof in any manner authorized or permitted under 
said UCC after default by a debtor, and to apply the proceeds thereof toward 
payment of any costs and expenses and attorneys' fees and expenses thereby 
incurred by Agent and toward payment of the Obligations in such order or 
manner as Agent may elect.  Specifically and without limiting the foregoing, 
Agent shall have the right to take possession of all or any part of the 
Pledged Collateral or any security thereof and of all books, records, papers 
and documents of Pledgor or in Pledgor's possession or control relating to 
the Pledged Collateral which are not already in Agent's possession, and for 
such purpose may enter upon any premises upon which any of the Pledged 
Collateral or any security therefor or any of said books, records, papers and 
documents are situated and remove the same therefrom without any liability 
for trespass or damages thereby occasioned. To the extent permitted by law, 
Pledgor expressly waives any notice of sale or other disposition of the 
Pledged Collateral and all other rights or remedies of Pledgor or formalities 
prescribed by law relative to sale or disposition of the Pledged Collateral 
or exercise of any other right or remedy of Agent existing after default 
hereunder; and to the extent any such notice is required and cannot be 
waived, Pledgor agrees that if such notice is given in the manner provided in 
SECTION 14 hereof at least ten days before the time of the sale or 
disposition, such notice shall be deemed reasonable and shall fully satisfy 
any requirement for giving of said notice.  Agent shall not be obligated to 
make any sale of Pledged Collateral regardless of notice of sale having been 
given. Agent may adjourn any public or private sale from time to time by 
announcement at the time and place fixed thereof, and such sale may, without 
further notice, be made at the time and place to which it was so adjourned.

     (b)  Upon notice by Agent to Pledgor, Agent or its nominee or nominees 
shall have the sole and exclusive right to exercise all voting and consensual 
powers pertaining to the Pledged Collateral or any part thereof and may 
exercise such powers in such manner as Agent may elect.

     (c)  All dividends, payments of interest and other distributions of 
every character made upon or in respect of the Pledged Collateral or any part 
thereof shall be deemed to be Pledged Collateral and shall be paid directly 
to and shall be held by Agent as additional Pledged Collateral pledged under 
and subject to this Pledge Agreement.

     (d)  All rights to marshaling of assets of Pledgor, including any such 
right with respect to the Pledged Collateral, are hereby waived by Pledgor.

     (e)  All recitals in any instrument of assignment or any other 
instrument executed by Agent incident to sale, lease, transfer, assignment or 
other disposition, lease or utilization of the Pledged Collateral or any part 
thereof hereunder shall be full proof of the matters stated therein and no 
other proof shall be requisite to establish full legal propriety of the sale 
or other action taken by Agent or of any fact, condition or thing incident 
thereto, and all requisites of such sale or other action or of any fact, 
condition or thing incident thereto shall be presumed conclusively to have 
been performed or to have occurred.

     9.   SPECIAL PROVISIONS FOR PLEDGED STOCK.

     Pledgor hereby acknowledges that the sale by Agent of any of the Pledged 
Stock pursuant to the terms hereof in compliance with applicable federal or 
state securities laws (as now in effect or as hereafter amended, or any 
similar statute hereafter adopted with similar purpose or effect, the 
"Securities Laws") may require strict limitations as to the manner in which 
Agent or any subsequent transferee of the Pledged Stock may dispose of such 
securities.  Pledgor understands that in order to protect Agent's interest it 
may be necessary to sell the Pledged Stock at a price less than the maximum 
price attainable if a sale were delayed or were made in another manner, such 
as a public offering requested under the Securities Laws.  Pledgor has no 
objection to a sale in such a manner.

     10.  APPLICATION OF PROCEEDS BY AGENT.

     In the event Agent sells or otherwise disposes of the Pledged Collateral 
in the course of exercising the remedies provided for in SECTION 8 hereof, 
any amounts held, realized or received by Agent pursuant to the provisions 
hereof, including the proceeds of the sale of any of the Pledged Collateral 
or any part thereof, shall be applied by Agent first toward the payment of 
any costs and expenses incurred by Agent in enforcing this Pledge Agreement, 
in realizing on or protecting any Pledged Collateral and in enforcing or 
collecting any Obligations or any guaranty thereof, including, without 
limitation, the reasonable, actual attorneys' fees and expenses incurred by 
Agent (all of which costs and expenses are secured by the Pledged 
Collateral), all of which costs and expenses Pledgor agrees to pay, and then 
as provided in the Credit Agreement.  Any amounts and any Pledged Collateral 
remaining after such application and after payment to the Banks of all of the 
Obligations in full shall be paid or delivered to Pledgor, its successor or 
assigns, or as a court of competent jurisdiction may direct.

     Agent shall be deemed to have exercised reasonable care in the custody 
and preservation of the Pledged Collateral in its possession if the Pledged 
Collateral is accorded treatment substantially equal to that which Agent 
accords its own property, it being understood that Agent shall not have any 
responsibility for (x) ascertaining or taking action with respect to calls, 
conversions, exchanges, maturities, tenders or other matters relative to any 
Pledged Collateral, whether or not Agent has or is deemed to have knowledge 
of such matters or (y) taking any necessary steps to preserve rights against 
any parties with respect to any Pledged Collateral.

     11.  ABSOLUTE INTEREST.

     (a)  So long as any Obligations are unsatisfied, all rights of Agent 
hereunder, and all obligations of Pledgor hereunder, shall be absolute and 
unconditional irrespective of (i) any lack of validity or enforceability of 
any provision of the Credit Agreement, any agreement with respect to the 
Obligations or any other agreement or instrument relating to any of the 
foregoing, (ii) any change in the time, manner or place of payment of, or in 
any other term of, all or any of the Obligations, or any other amendment or 
waiver of or any consent to any departure from the Credit Agreement or any 
other agreement or instrument, (iii) any exchange, release or non-perfection 
of any Pledged Collateral, or any release or amendment or waiver of or any 
consent to or departure from any guarantee, for all or any of the Obligations 
or (iv) any other circumstance which might constitute 


                                       -8-

<PAGE>

a defense available to, or a discharge of, Pledgor in respect of the 
Obligations or this Pledge Agreement.

     (b)  This Pledge Agreement shall not be construed as relieving Pledgor 
from full liability on the Obligations and any and all future and other 
indebtedness secured hereby and for any deficiency thereon.

     (c)  Agent is hereby subrogated to all of Pledgor's interests, rights 
and remedies in respect to the Pledged Collateral and all security now or 
hereafter existing with respect thereto and all guaranties and endorsements 
thereof and with respect thereto.

     12.  TERMINATION.

     This Pledge Agreement and the security interests created hereunder shall 
terminate when all the Obligations have been indefeasibly paid in full and 
when Agent has no further obligation to extend credit under the Credit 
Agreement, at which time Agent shall execute and deliver to Pledgor all 
documents which Pledgor shall reasonably request to evidence termination of 
such security interest and shall return physical possession of any Pledged 
Collateral then held by Agent to Pledgor; PROVIDED, HOWEVER, that all 
indemnities of Pledgor contained in this Pledge Agreement shall survive, and 
remain in full force and effect regardless of the termination of the security 
interest of this Pledge Agreement.

     13.  ADDITIONAL INFORMATION.

     Pledgor agrees to furnish Agent from time to time such additional 
information and copies of such documents relating to this Pledge Agreement, 
the Pledged Collateral, the Obligations and Pledgor's financial condition to 
the extent and at such times as provided under Section 5.1(h) of the Credit 
Agreement as Agent may reasonably request.

     14.  NOTICES.

     Any communication, notice or demand to be given hereunder shall be in 
writing (including  telex  and  facsimile  communication)  and  mailed,  sent 
by  facsimile,  or  delivered,

     15.  INDEMNITY AND EXPENSES.

     The Pledgor agrees to indemnify Agent from and against any and all 
claims, losses and liabilities growing out of or resulting from this Pledge 
Agreement (including, without limitation, enforcement of this Pledge 
Agreement and other Collateral Documents, and all claims and demands of all 
persons at any time claiming the Pledged Collateral or any interest therein), 
except claims, losses or liabilities resulting from Agent's gross negligence 
or willful misconduct. Pledgor agrees to pay on demand all out-of-pocket 
expenses of the Agent (including the reasonable fees and expenses of Agent's 
attorneys, experts and agents) in any way relating to the enforcement or 
protection of the rights of the Banks hereunder and further agrees that the 
Pledged Collateral secures such payment.

     16.  NO WAIVER; CUMULATIVE RIGHTS.

     No failure on the part of Agent to exercise, and no delay in exercising, 
any right, remedy or power hereunder shall operate as a waiver thereof, nor 
shall any single or partial exercise by Agent of any right, remedy or power 
hereunder preclude any other or future exercise of any other right, remedy or 
power.  Each and every right, remedy and power hereby granted to Agent or 
allowed it by law or other agreement shall be cumulative and not exclusive of 
any other and may be exercised by Agent from time to time.

     17.  GOVERNING LAW; CONSENT TO JURISDICTION.

     THIS AGREEMENT AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES HEREUNDER, 
SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE 
OF COLORADO, WITHOUT, HOWEVER, GIVING EFFECT TO THE CONFLICTS OF LAW 
PROVISIONS THEREOF.  PLEDGOR, FOR ITSELF AND ITS SUCCESSORS AND ASSIGNS,

PROCEEDING AGAINST PLEDGOR ARISING OUT OF OR RELATING TO THIS AGREEMENT, THE 
TRANSACTIONS CONTEMPLATED HEREBY OR THE SUBJECT MATTER HEREOF MAY BE

     18.  JURY TRIAL.

     PLEDGOR HEREBY KNOWINGLY, VOLUNTARILY, INTENTIONALLY, IRREVOCABLY AND

                         PROVISIONS CONCERNING ACCOUNTS

     SECTION 3.1    Office and Records of Debtor.  Debtor's chief executive 
office is located at:  1903 North Harrison Avenue, Cary, North Carolina 
27513. Debtor maintains all of its records with respect to its Accounts in

with respect to its Accounts at any other location except after thirty (30) 
days prior written notice to the Agent.

     SECTION 3.2    Representations.  Debtor represents and warrants that 
each Account of the Debtor at the time of its assignment to Agent (a) will be 
owned solely by Debtor; (b) will be for a liquidated amount maturing as 
stated in Debtor's Books; (c) will be a bona fide existing obligation created 
by the final sale and delivery of goods or the rendition of services to 
Account Debtors by Debtor in the ordinary course of its business; and (d)

privilege, or other condition, except as reflected on Debtor's Books.

     SECTION 3.3    Shipment Arrangements.  After two (2) weeks notice, 
unless an Event of Default has occurred then promptly upon the request of the 
Agent, Debtor shall deliver to Agent, as Agent may request no more often than 
annually, so long as an Event of Default has not occurred, copies of delivery 
receipts, customer purchase orders, shipping instructions, bills of lading, 
and other documentation respecting shipment arrangements.  Absent such a 
request by Agent, copies of all such documentation shall be held by Debtor as 
custodian for Agent.

     SECTION 3.4    Agent's Rights.  Upon and after the occurrence of an 
Event of Default and at any time Agent reasonably believes an Event of 
Default has occurred or is likely to occur with the passage of time, any 
officer, employee, or agent of Agent shall have the right, at any time or 
times hereafter, in the name of Agent or its nominee (including Debtor), to 
verify the validity, amount, or any other matter relating to any Accounts by 
mail, telephone, or otherwise; and all reasonable costs thereof shall be 
payable by Debtor to Agent.  At such time, Agent or its designee may at any 
time notify customers or Account Debtors that Accounts have been assigned to 
Agent or of Agent's security interest therein and collect the same directly

hereunder, no discount, credit, or allowance shall be granted by Debtor to any
Account Debtor and no return of merchandise shall be accepted by Debtor without

net amounts received by Agent in payment of such disputed Accounts, after
deducting all Agent Expenses incurred in connection therewith.

                        PROVISIONS CONCERNING INVENTORY

     SECTION 4.1    Locations.  SCHEDULE 4.1(o) of the Credit Agreement is a
true and correct list showing all states where inventory is located (except for
Inventory in transit), including, without limitation, facilities leased and
operated by Debtor and locations neither owned nor leased by Debtor, and showing
all such places where Inventory of Debtor has been located in the past four
months.  Such list indicates whether the premises are those of a warehouseman or
other party.  No Inventory will be removed from states set forth in such
Schedule except for the purpose of sale in the ordinary course of Debtor's
business provided that Inventory may be moved from one location set forth in
such Schedule to another in the ordinary course of Debtor's business.  Debtor
will promptly notify Agent of any new Inventory location.

     SECTION 4.2    Inventory, Books and Records.  Debtor shall keep all
Inventory in good order and condition and shall maintain full, accurate, and
complete books and records with respect to Inventory at all times.

business hours and consistent with SECTION 5.1(m) of the Credit Agreement,
inspect and examine the Inventory and check and test the same as to quality,
quantity, value, and condition.

     SECTION 4.4    Sales of Inventory.  Subject to the rights of Agent upon the
occurrence of an Event of Default, Debtor may sell Inventory in the ordinary
course of its business (which does not include a transfer in full or partial
satisfaction of indebtedness or a transfer for less than fair equivalent value).

     SECTION 4.5    Warehouses and Landlords.  Except as set forth on
SCHEDULE 4.1(o) of the Credit Agreement, Inventory is not now and shall not at
any time hereafter be stored with a bailee, warehouse, or similar party without

     SECTION 5.1    Maintenance and Repair.  Debtor shall keep and maintain

that is not a fixture to become a fixture to real estate or an accession to
other property without the prior written consent of Agent, and the Equipment is
now and shall at all times remain personal property except with Agent's prior
written consent.  If any of the Collateral is or will be attached to real estate
in such a manner as to become a fixture under applicable state law and if such
real estate is encumbered and such encumbrance attaches to such Collateral,
Debtor will obtain from the holder of each Lien or encumbrance a written consent
and subordination to the security interest hereby granted, or a written
disclaimer of any interest in the Collateral, in a form acceptable to Agent in
its reasonable judgment.

     SECTION 5.3    Additional Acquisitions.  Debtor shall promptly notify Agent
in writing of its acquisition, by purchase, lease, or otherwise, of any material
after-acquired Equipment, including a description of the Equipment and of its

warrants that all of the General Intangibles assigned to Agent or in which

     (a)  A true and complete schedule setting forth all patents, federal and/or
state trademarks, service marks, trade name or brand name registrations and
copyright registrations, and all pending applications and applications (other
than intent to use applications) to be filed therefore, owned or controlled by
Debtor or licensed to Debtor is contained in SCHEDULE 2.1(d)(x) hereto.  No
licenses, sublicenses, covenants, or agreements have been entered into by Debtor
in respect of any of such items, and each such item is in full force and effect,
free and clear of all Liens and encumbrances of every nature, is not currently
being challenged in any way, and is not involved in any pending (or, to the
knowledge of Debtor, threatened) interference proceeding.

     (b)  Concurrently with its execution and delivery of this Security
Agreement and Assignment, Debtor shall execute and deliver to Agent collateral
assignments of all registered


                                     -9-

<PAGE>

patents, trademarks, trade names, copyrights, and applications (other than 
intent to use applications) for any of them, in a form satisfactory to Agent 
and suitable for recording in the records of the registering authority.

     SECTION 6.3    Contracts and Leases.

     (a)  SCHEDULE 4.1(o) and SCHEDULE 4.1(n) of the Credit Agreement are,
respectively, true and complete lists (i) of all leases of real property and
(ii) of all Material Agreements to which Debtor is a party.  Debtor represents
and warrants that each of the leases, contracts, and other agreements listed on
such Schedules is in full force and effect; that neither Debtor nor, to Debtor's
knowledge, any other party thereto is in default under or in breach of the terms
or conditions of any such lease, contract, or other agreement; and that there
has not occurred any event of default or event that, after the giving of notice
or the lapse of time or both, would constitute a default under or breach of any
such lease.

     (b)  Debtor shall not amend, modify or supplement any Material Agreement or
waive any provision thereof other than in the ordinary course of business,
without the prior written consent of the Agent, which consent will not be
unreasonably withheld.

     (c)  Debtor shall remain liable to perform all of its duties and
obligations under any leases, contracts, and agreements included in the
Collateral to the same extent as if this Security Agreement and Assignment had
not been executed, and Agent shall not have any obligation or liability under

Assignment or otherwise.

                                      Section 7

                        OTHER PROVISIONS CONCERNING COLLATERAL

     SECTION 7.1    Title.  Debtor has good title to the Collateral, and the
Liens granted to Agent pursuant to this Security Agreement and Assignment are
fully perfected first priority Liens in and to the Collateral with priority over
the rights of every person in the Collateral other than the rights of Debtor and
other than Permitted Liens, and the Collateral is free, clear, and unencumbered
by any Liens in favor of any person other than Agent except for Permitted Liens.

     SECTION 7.2    Further Assurances.  Debtor shall execute and deliver to
Agent, concurrent with Debtor's execution of this Security Agreement and
Assignment and at any time or times hereafter at the request of Agent, all
financing statements, continuation financing statements, fixture filings,
security agreements, chattel mortgages, assignments, endorsements of
certificates of title, applications for titles, affidavits, reports, notices,
schedules of accounts, letters of authority, and all other documents Agent may
reasonably request, in form satisfactory to Agent, to perfect and


                                    -10-

<PAGE>

maintain perfected Agent's Liens in the Collateral and in order to consummate 
fully all of the transactions contemplated under the Loan Documents.  Debtor 
hereby irrevocably makes, constitutes, and appoints Agent (and any of Agent's 
officers, employees, or agents designated by Agent) as Debtor's true and 
lawful attorney with power to sign the name of Debtor on any of the 
above-described documents or on any other similar documents that need to be 
executed, recorded, and/or filed in order to perfect or continue perfected 
Agent's Liens in the Collateral.  The appointment of Agent as Debtor's 
attorney is irrevocable as long as any Secured Obligations are outstanding.  
Any person dealing with Agent shall be entitled to rely conclusively on any 
written or oral statement of Agent that this power of attorney is in effect.

     SECTION 7.3    Transfer of Collateral.  Debtor shall not sell, lease,
license, transfer, or otherwise dispose of any interest in any Collateral except
for sales of Inventory in the ordinary course of its business (sales of
Inventory in full or partial satisfaction of existing obligations of Debtor are
not considered to be sales in the ordinary course of business) and except for
sales, transfers or other dispositions permitted by SECTION 5.2(g) of the Credit
Agreement.

     SECTION 7.4    Agent's Duty of Care.  Agent shall have no duty of care with
respect to the Collateral except that Agent shall exercise reasonable care with
respect to the Collateral in Agent's custody.  Agent shall be deemed to have
exercised reasonable care if such property is accorded treatment substantially
equal to that which Agent accords its own property or if Agent takes such action
with respect to the Collateral as the Debtor shall request or agree to in
writing, provided that no failure to comply with any such request nor any
omission to do any such act requested by the Debtor shall be deemed a failure to
exercise reasonable care.  Agent's failure to take steps to preserve rights
against any parties or property shall not be deemed to be failure to exercise
reasonable care with respect to the Collateral in Agent's custody.  All risk of
loss, damage, or destruction of the Collateral shall be borne by Debtor.

     SECTION 7.5    Debtor's Contracts.  Debtor shall remain liable to perform
its obligations under any contracts and agreements included in the Collateral to
the same extent as though this Security Agreement and Assignment had not been
entered into, and Agent shall not have any obligation or liability under such
contracts and agreements by reason of this Security Agreement and Assignment or
otherwise.

     SECTION 7.6    Reinstatement of Liens.  If at any time after payment in
full of all Secured Obligations and termination of Agent's Liens, any payment on
Secured Obligations previously made must be disgorged by Agent for any reason
whatsoever (including, without limitation, the insolvency, bankruptcy, or
reorganization of Debtor or any Guarantor), this Security Agreement and
Assignment and Agent's Liens granted hereunder shall be reinstated as to all
disgorged payments as though such payments had not been made, and Debtor shall
sign and deliver to Agent all documents and things necessary to reperfect all
terminated Liens.


                                    -11-

<PAGE>

     SECTION 7.7    Agent Expenses.  If Debtor fails to pay any moneys (whether
taxes, assessments, insurance premiums, or otherwise) due to third persons or
entities, fails to make any deposits or furnish any required proof of payment or
deposit, or fails to discharge any Lien prohibited hereby, all as required under
the terms of this Security Agreement and Assignment, then Agent may, to the
extent that it determines that such failure by Debtor could have a material
adverse effect on Agent's interests in the Collateral, in its discretion and
with three (3) days prior notice to Debtor, make payment of the same or any part
thereof.  Any amounts paid or deposited by Agent shall constitute Agent
Expenses, shall become part of the Secured Obligations and shall be secured by
the Collateral.  Any payments made by Agent shall not constitute (a) an
agreement by Agent to make similar payments in the future or (b) a waiver by
Agent of any Event of Default under this Security Agreement and Assignment. 
Agent need not inquire as to, or contest the validity of, any such expense, tax,
security interest, encumbrance, or Line, and the receipt of the usual official
notice for the payment of moneys to a governmental entity shall be conclusive
evidence that the same was validly due and owing.

     Debtor shall immediately and without demand reimburse Agent for all sums
expended by Agent that constitute Agent Expenses, and Debtor hereby authorizes
and approves all advances and payments by Agent for items constituting Agent
Expenses.

     SECTION 7.8    Inspection of Collateral and Records.  Subject to and
consistent with the provisions of SECTIONS 5.1(h) and 5.1(m) of the Credit
Agreement, during Debtor's usual business hours, Agent may inspect and examine
the Collateral and check and test the same as to quality, quantity, value and
condition.  Agent shall also have the right at any time or times hereafter,
during Debtor's usual business hours or during the usual business hours of any
third party having control over the records of Debtor, to inspect and verify
Debtor's Books in order to verify the amount or condition of, or any other
matter relating to, the Collateral and Debtor's financial condition and to copy
and make extracts therefrom.  Debtor waives the right to assert a confidential
relationship.  If any, it may have with any accounting firm and/or service
bureau in connection with any information requested by Agent pursuant to this
Security Agreement and Assignment and agrees that Agent may directly contact any
such accounting firm and/or service bureau in order to obtain such information.

                                      COVENANTS

     SECTION 8.1    Encumbrance of Assets.  Debtor shall not create, incur,
assume, or permit to exist any Lien on any asset now owned or hereafter acquired
by Debtor, except for Liens to Agent and Permitted Liens or as otherwise
provided by SECTION 5.2(c).


                                    -12-

     SECTION 8.2    Condition and Repair.  Debtor shall maintain in good repair
and working order all properties used in its business and from time to time
shall make all appropriate repairs and replacements thereof.

     SECTION 8.3    Insurance.  Debtor shall maintain, with financially sound
and reputable insurers, insurance with respect to the Collateral against loss or
damage of the kinds and in the amounts customarily insured against by
corporations of established reputation engaged in the same or similar
businesses.  Each such policy shall name Agent as an additional insured and,
where applicable, as loss payee under a lender loss payable endorsement
satisfactory to Agent and shall provide for thirty (30) days' written notice to
Agent before such policy is altered or canceled.  Debtor shall provide evidence
satisfactory to Agent that all such coverages are in full force and effect.

                                      Section 9

                                  EVENTS OF DEFAULT

     Any of the following events shall be deemed an Event of Default or a
default hereunder:

     (a)  if default shall be made in payment or performance of any Secured
Obligations as and when the same shall become due and payable after the
expiration of the applicable grace period, if any; or

     (b)  if Debtor fails to perform or observe any other term, provision,
covenant or agreement of this Security Agreement and Assignment (within 15 days
of Debtor's receipt of written notice or actual knowledge thereof) or in any of
the Loan Instruments to which it is a party, and Debtor shall not cure such
failure within the applicable grace period, if any; or

     (c)  if there occurs an event of default under the Credit Agreement or any
other Loan Instrument; or

     (d)  if any warranty, representation, certification, financial statement or
other information made or furnished at any time pursuant to the terms of this
Security Agreement and Assignment, by Debtor or any Guarantor, shall prove to be
materially false as of the date made.

                                      Section 10

                                       REMEDIES

     SECTION 10.1   General Remedies.  Upon the occurrence of any Event of
Default, in addition to all other rights, powers and remedies conferred herein,
in the Credit Agreement or by law, the Agent may declare the Secured Obligations
immediately due, payable and performable, including


                                    -13-

<PAGE>

all principal and interest remaining unpaid on the Debtor's Notes and all 
other amounts secured hereby, all without demand, presentment or notice, all 
of which are expressly waived.  The Agent shall also have, in addition to all 
other rights provided herein, in the Credit Agreement, or by law, the rights 
and remedies of Agent under the Code and applicable common law (regardless of 
whether the Code is the law of the jurisdiction where the rights or remedies 
are asserted and regardless of whether the Code applies to the affected 
Collateral), and further, but not by way of limitation, the Agent may take 
(and/or may cause one or more of its designees to take) any or all of the 
following actions upon the occurrence of any Event of Default:

     (a)  Notify other parties with respect to or interested in any item of the
Collateral of the Agent's interest therein or of any action proposed to be taken
with respect thereto, and direct one or more of those parties to make all
payments, distributions and proceeds otherwise payable to the Debtor with
respect thereto directly to the Agent or its order until notified by the Agent
that all the Secured Obligations have been fully paid and satisfied.

     (b)  Require the Debtor to, and the Debtor hereby agrees that it shall at
its expense and upon request of the Agent forthwith, assemble all or part of the
Collateral as directed by the Agent and make it available to the Agent at a
place to be designated by the Agent reasonably convenient to both parties.

     (c)  Receive and retain all payments, distributions and proceeds of any
kind with respect to any and all of the Collateral.

     (d)  Enter any premises where any item of Collateral may be located, with
or without permission or process of law but without breach of the peace, and
seize and remove such Collateral or remain upon such premises and use or dispose
of such Collateral as contemplated under this Security Agreement and Assignment.

     (e)  Request the judicial appointment of a receiver respecting the
Collateral or any portion thereof in any action, suit or proceeding in which
claims are asserted against the Collateral by the Agent or its designee,
irrespective of the solvency of the Debtor or any other person or the adequacy
of any Collateral, and without notice to or the approval of the Debtor, which
receiver shall have the power to manufacture, operate, sell, lease or rent such
items of Collateral pending the sale of all of the Collateral and to collect the
rent, issues and profits therefrom, together with such other powers as may have
been requested by the Agent and shall apply the amounts received (net of all
proper charges and expenses) to the Obligations as provided in this Security
Agreement and Assignment.  Such a receiver may serve without bond or under such
minimal bond as may be required by applicable law.

     (f)  Reduce its claim to judgment or foreclose or otherwise enforce, in
whole or in part, the security interest created hereby by any available judicial
procedure.


                                    -14-

<PAGE>

     (g)  Take any action with respect to the offer, sale, lease or other
disposition, and delivery of the whole of, or from time to time any one or more
items of, the Collateral, including, without limitation:  to sell, assign, lease
or otherwise dispose of the whole of, or from time to time any part of, the
Collateral, or offer or agree to do so, in any established market or at any
broker's board, private sale or public auction or sale (with or without demand
on the Debtor or any advertisement or other notice of the time, place or terms
of sale, except such reasonable notice of the time and place of any public sale
or the time after which a private sale or other disposition may be made as may
be required by the Code) for cash, credit or any other asset or property, for
immediate or future delivery, and for such consideration and upon such terms and
subject to such conditions as the Agent in its sole and absolute discretion may
determine.  The requirements of reasonable notice shall be met if such notice is
mailed or delivered to the Debtor at the address designated at SECTION 12.4 at
least ten (10) days before the time of the sale or disposition.  The Agent may
purchase (the consideration for which may consist in whole or in part of
cancellation of indebtedness) or any other person may purchase the whole or any
one or more items of the Collateral so sold free and clear of any and all
rights, powers, privileges, remedies and interests of the Debtor (which the
Debtor has expressly waived); to postpone or adjourn any such auction, sale or
other disposition or cause the same to be postponed or adjourned from time to
time to a subsequent time and place, or to abandon or cause the abandonment of
the same, all without any advertisement or other notice thereof; and to carry
out any agreement to sell any item or items of the Collateral in accordance with
the terms and provisions of such agreement, notwithstanding that, after the
Agent shall have entered into such an agreement, all the Obligations may have
been paid and satisfied in full.  Agent may dispose of the Collateral in its
then existing condition or, at its election, may take such measures as it deems
necessary or advisable to refurbish, repair, improve, process, finish, operate,
demonstrate, and prepare for sale the Collateral and may store, ship, reclaim,
recover, protect, advertise for sale or lease, and insure the Collateral.

     (h)  Pay, purchase, contest, or compromise any encumbrance, charge, or Lien
that, in the opinion of Agent, appears to be prior or superior to its Lien and
pay all expenses incurred in connection therewith.

     (i)  Agent may (i) notify Account Debtors to make payment on Accounts, and
General Intangibles directly to Agent; (ii) settle, adjust, compromise, extend,
or renew Accounts, or General Intangibles, either before or after legal
proceedings to collect such Accounts, or General Intangibles have commenced;
(iii) prepare and file any bankruptcy proofs of claim or similar documents
against any Account Debtor; (iv) prepare and file any notice, assignment,
satisfaction, or release of Lien, UCC termination statement, or any similar
document; (v) sell or assign Accounts, and General Intangibles, individually or
in bulk, upon such terms, for such amounts, and at such time or times as Agent
deems advisable; and (vi) complete the performance required of Debtor under any
contract or agreement to which Debtor is a party and out of which Accounts, or
General Intangibles arise or may arise.  Agent may use and operate Debtor's
Equipment for all such purposes.


                                    -15-

<PAGE>

     (j)  Agent may (i) endorse Debtor's name on all checks, notes, drafts,
money orders, or other forms of payment of or security for Accounts or other
Collateral; (ii) sign Debtor's name on drafts drawn on Account Debtors or
issuers of letters of credit; and (iii) notify the postal authorities in
Debtor's name to change the address for delivery of Debtor's mail to an address
designated by Agent, receive and open all Mail addressed to Debtor, copy all
mail, retain copies of all mail relating to Collateral, and hold all mail
available for pickup by Debtor.

     (k)  Exercise any voting, consent, enforcement or other right, power,
privilege, remedy or interest of the Debtor pertaining to any item of Collateral
to the same extent as if the Agent were the outright owner thereof.

     (l)  Take possession of and thereafter deal with or use from time to time
all or any part of the Collateral in all respects as if the Agent were the
outright owner thereof.

     (m)  At the Agent's sole and absolute discretion, retain the Collateral or
any part thereof in satisfaction of the Secured Obligations.

     (n)  Transfer or cause the transfer of the ownership of all or any part of
the Collateral to its own name and have such transfer recorded in any
jurisdiction(s) and publicized in any manner deemed appropriate by the Agent.

     SECTION 10.2   Non-Judicial Remedies.  In granting to the Agent the power
to enforce its rights hereunder without prior judicial process or judicial
hearing, the Debtor expressly waives, renounces and knowingly relinquishes any
legal right which might otherwise require the Agent to enforce its rights by
judicial process.  In so providing for non-judicial remedies, the Debtor
recognizes and concedes that such remedies are consistent with the usage of
trade, are responsive to commercial necessity, and are the result of a bargain
at arm's length.  Nothing herein is intended to prevent the Agent from resorting
to judicial process at its option.

     SECTION 10.3   Proceeds.  The Agent shall collect the cash and non-cash
proceeds received from any sale or other disposition or from any other source
contemplated by SECTION 10.1, and, after deducting all reasonable costs and
expenses incurred by the Agent and any person designated by the Agent to take
any of the action enumerated in this Security Agreement and Assignment in
connection with such collection and sale or disposition (including reasonable
attorneys' disbursements, expenses and reasonable fees and the reasonable fees
and expenses of any appraisers or consultants employed by Agent), the Agent in
its discretion may retain the same as additional or substitute Collateral or may
apply the same in accordance with the terms and provisions of this Security
Agreement and Assignment.  In the event any funds remain after satisfaction in
full of the Secured Obligations, then the remainder shall be returned to the
Debtor, subject, however, to any other rights or interests the Agent may have
therein under any other instrument, agreement or document or applicable law.

     SECTION 10.4   Application of Proceeds.  Any funds received from or on
behalf of the Debtor (whether pursuant to the terms and provisions of this
Security Agreement and Assignment or otherwise) by the Agent shall be applied to
the following items in such manner and order as the Agent may determine in its
sole and absolute discretion.

     (a)  The payment to or reimbursement for any fees and expenses for which
the Agent is entitled to be paid or reimbursed pursuant to any of the provisions
of this Security Agreement and Assignment.

     (b)  The payment of accrued and unpaid interest on the Secured Obligations.

     (c)  The payment of the outstanding principal on the Secured Obligations.

     (d)  The payment in full of all other Obligations under this Security
Agreement and Assignment.

All advances and payments made pursuant to this Security Agreement and
Assignment may be recorded by the Agent on its books and records, and such books
and records shall be conclusive absent manifest error as to the existence and
amounts thereof.

     SECTION 10.5   Deficiency.  If the amount of all proceeds received with
respect to and in liquidation of the Collateral that shall be applied to payment
of the Secured Obligations shall be insufficient to pay and satisfy all of the
Secured Obligations in full, the Debtor acknowledges that it shall remain liable
for any deficiency, together with interest thereon and costs of collection
thereof (including attorneys' disbursements, expenses and reasonable fees and
the reasonable fees of any appraisers or consultants employed by Agent), and in
accordance with the terms and provisions of this Security Agreement and
Assignment.

     SECTION 10.6   Other Recourse.  The Debtor waives any right to require the
Agent to proceed against any other person, exhaust or marshal any Collateral or
other security for the Secured Obligations, or pursue any other remedy in the
Agent's power.  Until all of the Secured Obligations shall have been paid in
full, the Debtor shall have no right to subrogation and the Debtor waives the
right to enforce any remedy which the Agent has or may hereafter have against
any other party liable for the Secured Obligations, and waives any benefit of
and any right to participate in any other security whatsoever now or hereafter
held by the Agent.

     SECTION 10.7   Remedies Not Exclusive.  All rights, powers and remedies
conferred in this SECTION 10 are cumulative, and not exclusive, of:  (i) any and
all other rights and remedies herein conferred or provided for; (ii) any and all
other rights, powers and remedies conferred or provided for in the Credit
Agreement or in any other Loan Document; and (iii) any and all rights, powers
and remedies conferred, provided for or existing at law or in equity, and the
Agent shall, in addition to


                                    -17-

<PAGE>

the rights, powers and remedies herein conferred or provided for, be entitled 
to avail itself of all such other rights, powers and remedies as may now or 
hereafter exist at law or in equity for the collection of and enforcement of 
the Secured Obligations and the enforcement of the representations, 
warranties, agreements, covenants and indemnities contained in this Security 
Agreement and Assignment, the Credit Agreement and in any other Loan 
Document.  The Agent, in its sole discretion, may proceed to exercise or 
enforce any right, power, privilege, remedy or interest that the Agent may 
have under this Security Agreement and Assignment, the Credit Agreement any 
other Loan Document, or applicable law, without notice except as otherwise 
expressly provided herein; without pursuing, exhausting or otherwise 
exercising or enforcing any other right, power, privilege, remedy or interest 
that the Agent may have against or in respect of the Debtor or the 
Collateral, or other person or thing, and without regard to any act or 
omission of the Agent or any other person.  The Agent may institute separate 
proceedings with respect to this Security Agreement and Assignment in such 
order and at such times as the Agent may elect in its sole and absolute 
discretion.  This Security Agreement and Assignment may be enforced without 
possession of any Note or its production in any action, suit or proceeding.

     SECTION 10.8   Equitable Relief.  The Debtor acknowledges that it will be
impossible to measure in money the damage to the Agent in the event of a breach
of any of the terms and provisions of this Security Agreement and Assignment,
and the Debtor agrees that, in the event of any such breach, the Agent will not
have an adequate remedy at law, although the foregoing shall not constitute a
waiver of any of the Agent's rights, powers, privileges and remedies against or
in respect of a breaching party, any Collateral or any other person or thing
under this Security Agreement and Assignment or applicable law.  It is therefore
agreed that the Agent, in addition to all other such rights, powers, privileges
and remedies that it may have, shall be entitled to injunctive relief, specific
performance or such other equitable relief as the Agent may request to exercise
or otherwise enforce any of the terms and provisions of this Security Agreement
and Assignment and to enjoin or otherwise restrain any act prohibited thereby,
and the Debtor will not urge and hereby waives any defense that there is an
adequate remedy of law.

     SECTION 10.9   License.  Agent is hereby granted a license or other right
to use, without charge, Debtor's patents, copyrights, trade secrets, technical
processes, rights of use of any name, trade names, trademarks, labels, and
advertising matter, or any property of a similar nature, as it pertains to the
Collateral, in completing production of, advertising for sale, and selling any
Collateral, and Debtor's rights under all licenses and shall inure to Agent's
benefit.

     SECTION 10.10  Power of Attorney.  Debtor hereby appoints Agent (and any of
Agent's officers, employees, nominees, designees or agents designated by Agent)
as Debtor's attorney, with power after the occurrence of an Event of Default and
at any time Agent reasonably believes an Event of Default has occurred or is
likely to occur with the passage of time, with respect to the various assets and
properties included in the Collateral, and in addition to any other powers of
attorney contained herein:  (a) to take possession of and endorse (to Agent or
otherwise) Debtor's


                                    -18-

<PAGE>

name on any checks, bills of exchange, notes, acceptances, money orders, 
drafts, or other documents, forms of payment or security received in payment 
for or on account of those assets and properties; (b) demand, collect and 
receive any monies due on account of those assets and properties and give 
receipts and acquittances in connection therewith; (c) negotiate and 
compromise any claim, and commence, prosecute, defense, settle or withdraw 
and claims, suits or proceedings pertaining to or arising out of those assets 
and properties; (d) pay any indebtedness or other liability or perform any 
other Secured Obligation required to be paid or performed under this Security 
Agreement and Assignment or the Credit Agreement by the Debtor; (e) prepare 
and execute on behalf of the Debtor any mortgage, financing statement or 
other evidence of a security interest contemplated by this Security Agreement 
and Assignment, or any modification, refiling, continuation or extension 
thereof; (f) to sign Debtor's name on drafts against Account Debtors, on 
schedules and assignments of Accounts, on verifications of Accounts, and on 
notices to Account Debtors; (g) to notify the post office authorities to 
change the address for delivery of Debtor's mail to an address designated by 
Agent, to receive and open all mail addressed to Debtor, and to retain copies 
of all mail relating to the Collateral and hold all mail available for pick 
up by Debtor; (h) to send requests for verification of Accounts; (i) take any 
other action contemplated by this Security Agreement and Assignment or the 
Credit Agreement; (j) sign, execute, acknowledge, swear to, verify, deliver, 
file, record and publish any one or more of the foregoing; and (k) to do all 
things necessary to carry out this Security Agreement and Assignment.  The 
appointment of Agent as Debtor's attorney and each and every one of Agent's 
rights and powers, being coupled with an interest, are irrevocable as long as 
any Secured Obligations are outstanding. Any person dealing with Agent shall 
be entitled to rely conclusively on any written or oral statement of Agent 
that this power of attorney is in effect. This Power of Attorney shall 
survive the dissolution, reorganization or bankruptcy of the Debtor and shall 
extend to and be binding upon the Debtor's successors, assigns, heirs and 
legal representatives.  To the extent permitted by applicable law, the Debtor 
hereby ratifies and approves all acts of any such attorney and agrees that 
neither the Agent nor any such attorney will be liable for any acts or 
omissions nor for any error of judgment or mistake of fact or law other than 
their gross negligence, willful misconduct or unlawful misconduct.  Agent may 
also use Debtor's stationary  solely in connection with exercising its rights 
and remedies hereunder and performing the Obligations of Debtor.

     SECTION 10.11  Expenses Secured.  The Debtor agrees to pay on demand all
reasonable costs and expenses, if any (including reasonable counsel, consultant
and appraiser fees and expenses), in connection with the exercise and
enforcement (whether through negotiations, legal proceedings or otherwise) of
Agent's rights and remedies provided by this Security Agreement and Assignment,
the Credit Agreement or any other Loan Document, or which by law shall be
payable by the Debtor, expressly including all such costs and expenses incurred
by the Agent in connection with or during the pendency of any bankruptcy or
insolvency proceedings involving the Debtor or any Guarantor.  All such expenses
shall be part of the Secured Obligations, and shall be secured by the
Collateral.


                                    -19-

<PAGE>

     SECTION 10.12  Miscellaneous.  The Debtor acknowledges and agrees that the
rights, powers, privileges, remedies and interests conferred upon the Agent in
respect of the Collateral by this Security Agreement and Assignment and
applicable law are solely to enable the Agent to protect and preserve the
Collateral, as well as to realize upon it in accordance with this Security
Agreement and Assignment, all in such manner as the Agent in its discretion may
elect, and shall not impose upon the Agent any duty or other obligation to
exercise or enforce any such right, power, privilege, remedy or interest.  Any
exercise or other enforcement of any such right, power, privilege, remedy or
interest, if undertaken by the Agent in its discretion, may be delayed,
discontinued or otherwise not pursued or exhausted for any reason whatsoever
(whether intentionally or otherwise).  Without limiting the generality of the
foregoing, the Agent shall be under no duty or obligation to protect or preserve
any of the Collateral, perform any obligation or duty of the Debtor under any of
the Collateral, or take any action to mitigate or otherwise reduce any damage or
other loss or to otherwise collect, exercise or enforce any claim, right or
other interest arising under or with respect to the Collateral, except as
specifically provided in this Security Agreement and Assignment.

                                      Section 11

                                   RIGHT OF SET-OFF

     SECTION 11.1   Right of Set-Off.  Upon the occurrence and during the
continuance of any Event of Default, the Agent hereby is authorized at any time
and from time to time, without notice to the Debtor (any such notice being
hereby expressly waived by the Debtor), to set-off and apply, directly or
through any of its affiliates, custodians, participants and designees, any and
all deposits (whether general or special, time or demand, provisional or final,
or individual or joint) and other assets and properties at any time held in the
possession, custody or control of the Agent and any of its affiliates,
custodians, participants and designees, and any indebtedness or other amount at
any time held in the possession, custody or control of the Agent and any of its
affiliates, custodians, participants and designees, and any indebtedness or
other amount at any time owing by the Agent or any of its
affiliates or participants, to or for the credit, account or benefit of the 
Debtor against any and all of the Secured Obligations now or hereafter 
existing, whether or not the Agent shall have declared a default, accelerated 
the Secured Obligations or made any demand or taken any other action under 
this Security Agreement and Assignment, and although such Secured Obligations 
may be unmatured.  The Debtor acknowledges that pursuant to SECTION 2.1(f) 
hereof it granted to the Agent a senior security interest in and to, among 
other things, all such deposits, assets, properties and indebtedness in the 
possession of the Agent's affiliates, custodians, participants and designees, 
and the Debtor hereby authorizes any such person to so set-off and apply such 
amounts at such times and in such manner as the Agent may direct pursuant to 
this SECTION 11.1.  The Agent shall notify the Debtor after any such set-off 
and application; provided, however, that the failure to give such notice 
shall not affect the validity of such set-off and application.  In debiting 
any such account, the Secured Obligations shall be deemed to have been paid 
or repaid only to the extent of the funds actually available in the account 
notwithstanding any internal procedure of the Agent or any of its


                                    -20-

<PAGE>

affiliates, custodians, participants and designees to the contrary.  The 
rights of the Agent under this Section are in addition to and without 
limitation of any other rights, powers, privileges, remedies and other 
interests (including, without limitation, other rights of set-off and 
security interests) that the Agent may have under this Security Agreement and 
Assignment and applicable law.

                                      Section 12

                               MISCELLANEOUS PROVISIONS

     SECTION 12.1   Delay and Waiver.  No delay or omission to exercise any
right shall impair any such right or be a waiver thereof, but any such right may
be exercised from time to time and as often as may be deemed expedient.  A
waiver on one occasion shall be limited to that particular occasion.

     SECTION 12.2   Severability; Headings.  If any part of this Security
Agreement and Assignment or the application thereof to any person or
circumstance is held invalid, the remainder of this Security Agreement and
Assignment shall not be affected thereby.  The section headings herein are
included for convenience only and shall not be deemed to be a part of this
Security Agreement and Assignment.

     SECTION 12.3   Binding Effect.  This Security Agreement and Assignment
shall be binding upon and inure to the benefit of the respective legal
representatives, successors, and assigns of the parties hereto; however, Debtor
may not assign any of its rights or delegate any of its obligations hereunder. 
Agent (and any subsequent assignee) may transfer and assign this Security
Agreement and Assignment and deliver the Collateral to the assignee, who shall
thereupon have all of the rights of Agent; and Agent (or such subsequent
assignee who in turn assigns as aforesaid) shall then be relieved and discharged
of any responsibility or liability with respect to this Security Agreement and
Assignment and said Collateral.

     SECTION 12.4   Notices.  Any notices under or pursuant to this Security
Agreement and Assignment shall be deemed duly sent when delivered in hand or
