         Subordinated Notes (the "12% Notes"). The proceeds from the offering
         will be utilized to refinance the 12% Notes which mature in November
         1998. Approximately $3.4 million of the 12% Notes and cash has been
         received by the Company. Therefore, this portion of the 12% Notes has
         been classified as long-term debt at September 30, 1998.

         On November 6, 1998, the Company entered into a new Senior Credit
         Agreement with Bank One, Arizona, N.A. and Imperial Bank, Arizona. This
         new agreement replaces the Company's previous senior credit agreement
         and provides for an increase in capacity to a total of $30 million and
         can be expanded to encompass additional facilities. This agreement
         initially provides for a $20 million revolving line of credit, a $5
         million term note to refinance existing term debt secured by equipment
         and a $5 million term note to refinance certain existing subordinated
         debt. The Company will initially use approximately $2.3 million of the
         second term note to repay the remaining balance of the 12% Notes when
         they become due in November 1998. Therefore, this portion of the 12%
         Notes has been classified as long-term debt at September 30, 1998.

NOTE 4 - COMPREHENSIVE INCOME:

         The Company adopted Financial Accounting Standards No. 130, Reporting
         Comprehensive Income, on January 1, 1998. Comprehensive loss includes
         adjustments made for foreign currency translation. Comprehensive loss
         was ($444,160) and ($2,497,875) for the three months ended September
         30, 1998 and 1997, respectively, and ($6,464,283) and ($3,042,535) for
         the nine months ended September 30, 1998 and 1997, respectively.

NOTE 5 - EARNINGS PER SHARE:

         The following is a reconciliation of the numerators and denominators of
         basic and diluted per share computations. For the three months ended
         September 30, 1998 and 1997 and the nine months ended September 30,
         1997, earnings per share amounts are calculated using only weighted
         average outstanding shares. Options to purchase common stock and shares
         to be issued upon conversion of the Company's 8% Senior Subordinated
         Convertible Notes (the "8% Notes") and the Series C 10% Senior
         Subordinated Convertible Notes (the "10% Notes") of 4,308,111,
         4,468,980, and 4,525,616, respectively, for these periods were not used
         for computing dilutive earnings per share because the result would be
         anti-dilutive. For the nine month period ended September 30, 1998, the
         effects of 2,253,390 total shares to be issued upon conversion of the
         8% Notes and the 10% Notes were not used for computing dilutive
         earnings per share because the result would be anti-dilutive.

               NOTES TO INTERIM CONSOLIDATED FINANCIAL STATEMENTS

NOTE 6 - DISCONTINUED OPERATIONS:

         In 1998, the Company's board of directors adopted a plan to dispose of
         its rail and mass transit seating operations. Accordingly, the
         operating results of these rail and mass transit operations, including
         a provision for estimated loss upon disposition, have been segregated
         from continuing operations and are reported as discontinued operations.
         Interest expense has been allocated to discontinued operations based on
         the ratio of the discontinued operations' net assets to consolidated
         net assets. General corporate administrative expenses are not allocated
         to discontinued operations. Due to the subjective nature of estimated
         future operations and incremental costs of disposal, it is reasonably
         possible that these estimates may change in the future. Future changes
         in estimates will be included in the consolidated statement of
         operations in the reporting period determined. Revenues for the rail
         and mass transit operations were $4,360,279 and $5,202,258, for the
         three months ended September 30, 1998 and 1997, respectively, and
         $13,093,611 and $18,775,839 for the nine months ended September 30,
         1998 and 1997, respectively.

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

GENERAL - The following discussion and analysis provides information that
management of Simula, Inc. (the "Company") believes is relevant to an assessment
and understanding of the Company's results of operations and financial condition
for the three and nine month periods ended September 30, 1998 compared to the
same periods in 1997. This discussion should be read in conjunction with the
Interim Consolidated Financial Statements and the Notes thereto included
elsewhere in this Form 10-Q. This Form 10-Q contains certain forward-looking
statements and information. The cautionary statements contained below should be
read as being applicable to all related forward-looking statements wherever they
appear. See "Forward Looking Information and Risks of the Business."

OVERVIEW

         The Company designs and manufactures occupant safety systems and
devices engineered to safeguard human life in a wide range of air, ground, and
sea transportation vehicles. Utilizing its substantial proprietary technology in
energy-absorbing seating, inflatable restraints, and composite materials, the
Company focuses on reducing injury and increasing survivability in vehicle and
aircraft crashes.

         Since its founding in 1975, the Company's historic business has been as
a government and defense contractor. Additionally, commencing with acquisitions
and commercial products development since 1993, the Company has become the
largest North American-based supplier of seating systems for rail and other mass
transit vehicles and a successful new entrant in the manufacture of new
commercial airliner seating and inflatable restraints for automobiles. Utilizing
its proprietary safety technology, the Company has introduced crashworthy
systems for a variety of vehicles and aircraft including its 16g commercial
airliner passenger seat ("16g Seat") and various inflatable restraint systems
for automobiles including the Inflatable Tubular Structure ("ITS") (TM).

         In 1994, the Company made a strategic decision to enter the inflatable
restraint market for automobiles utilizing its proprietary technology, the ITS.
Through 1996, the Company completed its development of this technology and
start-up of its manufacturing facilities. In 1997, the Company began
manufacturing the ITS for sale to BMW, a major European automobile manufacturer,
which began including it in certain models of its automobiles in 1997.

         In 1993, the Company made a strategic decision to enter the commercial
aircraft seating market to bring its proprietary energy-absorbing technologies
to a new industry and take advantage of positive industry trends. To implement
its decision, the Company completed three acquisitions that allowed it to
develop the necessary infrastructure to support future growth. In 1993, the
Company acquired Airline Interiors, Inc. (the "Airline Acquisition"), which was
primarily involved with the refurbishment, reupholstery, reconditioning, and
reconfiguring of existing passenger seats. The Airline Acquisition provided
certain FAA certifications, enhanced the Company's management team and customer
base, and provided substantial assembly capacity. During 1994, the Company
acquired Coach and Car Equipment Corporation ("Coach and Car") and Artcraft
Industries Corp. ("Artcraft"). Coach and Car, and Artcraft's existing operations
included providing a majority of all manufacturing and refurbishment of rail and
mass transit seating systems in North America. These operations provided the
Company with the substantial large-scale manufacturing capacity and business
volume that were needed to establish the Company as a viable supplier of
commercial airliner seating systems.

         To continue it's strategic plan, in 1998 the Company adopted a plan to
sell its rail and mass transit seating operations at Coach and Car and Artcraft.
Because the Company's commercial airliner seating operation moved into a new
significantly larger facility in July 1998 and has established substantial
production, the rail operations are no longer required to demonstrate the
Company's production capabilities to current and potential airliner seating
customers. The Company believes the sale of these businesses will provide a
significant amount of cash that will be used to repay outstanding indebtedness
and reinvest in its other businesses that have higher current and projected
growth rates and financial returns. In addition, the sale will allow senior
Company management to focus on its other businesses. The Company has initiated
an active marketing plan and anticipates it will sell these operations as
ongoing businesses within twelve months. These companies will continue their
marketing, sales and manufacturing activities as the Company prepares them for
sale. The Company's rail and mass transit seating operations are reported as
discontinued operations.

         The Company is a holding company for wholly-owned subsidiaries, which
operate in three primary business segments. The Commercial Airline Seating
segment includes operations that primarily manufacture and refurbish seating
systems for domestic and foreign passenger airlines. The Government and Defense
segment includes operations that design and manufacture crash resistant
components, energy absorbing devices, ballistic armor and composites principally
for sale to branches of the United States armed forces. The Automobile Safety
Systems segment includes operations encompassing inflatable restraints,
principally the ITS, and related technologies for automobiles. In addition, the
Company maintains general corporate operations. The Company's rail and mass
transit seating operations are reported as discontinued operations.

         The Company's revenue has historically been derived principally from
sales of Company manufactured products. A substantial portion of its current
revenue is generated from long-term production contracts, which are accounted
for under the percentage of completion method of accounting. Under this method,
revenue is recorded as production progresses so that revenue less costs incurred
to date yields the percentage of gross margin estimated for each contract.
Overall gross margin percentages can increase or decrease based upon changes in
estimated gross margin percentages over the lives of individual contracts.

RESULTS FROM CONTINUING OPERATIONS

Three and nine Months Ended September 30, 1998 Compared to 1997:

         Revenue for the three months ended September 30, 1998 increased 28% to
$23.7 million from $18.4 million for the comparable period in 1997. Revenue for
the nine months ended September 30, 1998 increased 68% to $72.0 million from
$42.8 million for the comparable period in 1997. For the three months ended
September 30, 1998, the increase in revenue is primarily due to increased sales
of the ITS and increased Government and Defense revenue offset by a decrease in
16g Seat revenues. The decrease in 16g Seat revenues was due to the adverse
impact resulting from the complexity of new seat programs initiated in the third
quarter, and down time associated with the move into new production facilities
in July. For the nine months ended September 30, 1998, the increase in revenue
is due to increases in all of the Company's segments, the majority of which is
due to increased sales of the ITS and 16g Seats.

         Gross margin for the three months ended September 30, 1998 increased
139% to $5.5 million from $2.3 million for the comparable period in 1997. For
the nine months ended September 30, 1998, gross margin increased 73% to $18.1
million from $10.4 million for the comparable period in 1997. The increase in
gross margin was due to the increase in revenue noted above. As a percent of
sales, gross margin for the three months ended September 30, 1998 increased to
23% from 12%. For the nine months ended September 30, 1998, gross margin as a
percent of sales increased to 25% from 24%, for the comparable period in 1997.
These increases in gross margin percentages are principally due to significant
improvement in the gross margin percentage for the ITS. Revenue from the ITS in
1998 has increased substantially over 1997 and now provides significant
incremental margins over fixed production costs. In addition to realizing lower
revenue from the ITS in 1997, the Company was also incurring pre-contract costs
related to the final pre-production development of the ITS and start-up costs
related to its manufacturing facilities in Arizona and the United Kingdom during
this period. The increase in gross margin percentage from the ITS was partially
offset by lower margins in the Commercial Airline Seating segment. The high
concentration and complexity of new 16g Seat programs negatively impacted 16g
Seat margins in this segment in the third quarter of 1998 by resulting in lower
revenues and higher production costs. In addition, the introduction of new
manufacturing systems and procedures for production of 16g Seats is taking
longer to implement than was previously estimated and the estimated cost savings
have not yet been realized.

         Administrative expenses for the three months ended September 30, 1998
increased 8% to $5.1 million from $4.8 million for the comparable period in
1997. Administrative expenses for the nine months ended September 30, 1998
increased 10% to $14.2 million from $13.0 million for the comparable period in
1997. These increases were primarily attributable to the expansion of the
corporate and sales infrastructure related to the commercial introduction of the
ITS, including resources being utilized for sales and administration versus
pre-contract activities, research and development related to the expansion of
ITS technologies, and legal expenses.

<PAGE>   12
                                  SIMULA, INC.

         Interest expense decreased 3% to $1.3 million for the three months
ended September 30, 1998 from $1.4 million for the comparable period in 1997.
Interest expense for the nine months ended September 30, 1998 increased 11% to
$3.7 million from $3.4 million for the comparable period in 1997. This increase
was principally due the issuance of $34.5 million of the 8% Senior Subordinated
Convertible Notes (the "8% Notes") in April 1997 and to increased borrowings on
the Company's line of credit. These borrowings were made to fund the Company's
growth in working capital and fixed assets necessary to support the anticipated
growth in revenues for 1997 and subsequent years. These increases in interest
expense were partially offset by the conversion during the third quarter of 1997
of $9.6 million of the Series C 10% Senior Subordinated Convertible Notes (the
"10% Notes") into common stock of the Company.

         Interest income for the three and nine months ended September 30, 1998
represents income from the investment by the Company of available cash in high
quality government and short-term investment grade, interest bearing securities.

         The effective income tax rate for the three and nine month periods
ended September 30, 1998 and 1997 approximated the Company's combined statutory
rate of 40%.

DISCONTINUED OPERATIONS

         The net loss from discontinued operations was ($6.8) million for the
nine months ended September 30, 1998. Included in this amount is a net loss from
operations of the discontinued segment of ($2.1) million primarily resulting
from unabsorbed overhead costs principally due to production delays. The
remainder of the loss from discontinued operations of ($4.7) million represents
the write-down of the remaining net assets of these businesses to their net
realizable value based upon an independent valuation. This write-down was
principally comprised of the write-off of intangible assets and represented a
non-cash charge. Estimated costs of disposal and projected operating results
have been included in determining the net realizable value of these businesses.
Therefore, the Company does not anticipate that these operations will have any
significant impact on future results of operations during the period prior to
their sale. Due to the subjective nature of estimated future operations and
incremental costs of disposal, it is reasonably possible that these estimates
may change in the future. Future changes in estimates will be included in the
consolidated statement of operations in the reporting period determined.

LIQUIDITY AND CAPITAL RESOURCES

         The Company's liquidity is greatly impacted by the nature of the
billing provisions under its contracts. Generally, in the early period of
contracts, cash expenditures and accrued profits are greater than allowed
billings while contract completion results in billing previously unbilled costs
and profits. Contract and trade receivables, net of advances on contracts,
increased approximately $5.8 million for the nine months ended September 30,
1998 due principally to the throughput on certain Government and Defense
contracts and increased receivables from 16g Seat and ITS sales.

         Operating activities required the use of $13.1 million of cash during
the nine months ended September 30, 1998, compared to the use of $13.5 million
of cash during the same period in 1997. Cash used by operating activities in the
1998 period was primarily used to increase inventories $9.7 million and increase
contract and trade receivables as noted above. The increase in inventories was
primarily due to an increase in 16g Seat inventory necessary to support
anticipated future deliveries. In addition, delays in deliveries of 16g Seats
during the third quarter of 1998 resulted in an additional buildup of inventory.

         Investing activities required the use of $4.9 million of cash during
the nine months ended September 30, 1998, primarily for the purchase of property
and equipment. These purchases included manufacturing equipment for the ITS
located at the Company's facilities in Arizona and the United Kingdom, certain

         Financing activities provided $9.7 million of cash during the nine
months ended September 30, 1998 from $10.6 million in net borrowings under the
Company's line of credit and proceeds from the issuance of common stock
partially offset by principal payments under other debt arrangements for
scheduled maturities.

During the third quarter of 1998, the Company commenced a private offering of up
to $5.7 million principal amount of 9-1/2% Senior Subordinated Notes due
September 2003 (the "9-1/2% Notes"). This offering is being made pursuant to the
exemption from registration contained in Regulation D under the Securities Act
of 1933, as amended. Under the terms of this offering, purchases of the 9-1/2%
Notes may be made in cash or by tender for exchange of the Company's 12% Senior
Subordinated Notes (the "12% Notes"). The proceeds from the offering will be
utilized to refinance the 12% Notes which mature in November 1998. Approximately
$3.4 million of the 12% Notes and cash has been received by the Company.
Therefore, this portion of the 12% Notes has been classified as long-term debt
at September 30, 1998.

         On November 6, 1998, the Company entered into a new Senior Credit
Agreement with Bank One, Arizona, N.A. and Imperial Bank, Arizona. This new
agreement replaces the Company's previous senior credit agreement and provides
for an increase in capacity to a total of $30 million and can be expanded to
encompass additional facilities. This agreement initially provides for a $20
million revolving line of credit, a $5 million term note to refinance existing
term debt secured by equipment and a $5 million term note to refinance certain
existing subordinated debt. The Company will initially use approximately $2.3
million of the second term note to repay the remaining balance of the 12% Notes
when they become due in November 1998. Therefore, this portion of the 12% Notes
has been classified as long-term debt at September 30, 1998.

         The Company believes it has sufficient manufacturing capacity in place
at September 30, 1998 to meet its foreseeable delivery requirements. The Company
anticipates cash on hand, cash provided by operating activities once 16g Seat
production stabilizes, cash to be generated from the sale of its rail and mass
transit operations and the availability under its bank credit facilities will be
sufficient to meet its current and foreseeable working capital requirements. The
Company is also pursuing expansion of both its domestic and foreign senior debt
facilities and the sale of certain assets to increase its credit availability.
The Company may also, however, seek to obtain additional capital should demand
for its products exceed current capacity. The raising of additional capital in
public markets will be primarily dependent upon prevailing market conditions and
demand for the Company's technologies and products.

INFLATION

         The Company does not believe that it is significantly impacted by
inflation.

RESEARCH AND DEVELOPMENT

         The Company's research and development occurs under fixed-price,
government-funded contracts and Company-sponsored efforts. Historically,
research and development efforts have fluctuated based upon available
government-funded contracts and available Company funding. The Company
anticipates that future fluctuations may also occur as a result of efforts to
expand its inflatable restraint, commercial airliner and helicopter seating, and
other technologies.

SEASONALITY

         The Company does not believe that it is currently significantly
impacted by seasonal factors.

YEAR 2000 MATTERS

Background

         The Year 2000 issue is the result of computer programs being written
using two digits rather than four to define an applicable year. Any computer
programs or equipment that have time-sensitive software or embedded chips may
recognize a date using "00" as the year 1900 rather than the year 2000. This
could result in a system failure or miscalculations causing disruptions in
commerce, including among other things, a temporary inability to process
transactions, send invoices, or engage in similar normal business activities.

         The Company employs a number of information technology ("IT") systems
in its operations, including computer networking systems, hardware and software,
financial systems, and other similar systems. The Company also employs a number
of non-IT devices such as building security and safety devices, and other
devices containing embedded electronic circuits. Both IT systems and non-IT
devices are subject to potential failure due to the Year 2000 issue.

The Company's Year 2000 Plan

         In 1996, the Company initiated a plan for the conversion from existing
accounting software to new state-of-the-art, Year 2000-compliant, manufacturing
and accounting systems at each of its operating companies. That conversion is
part of an overall plan (the "Year 2000 Plan") the Company has developed to
achieve Year 2000 readiness. The Year 2000 Plan is intended to remediate the
Year 2000 issue in all categories of systems and electronic devices in use by
the Company, including IT and non-IT devices, so that the Company may continue
its operations without interruption or with minimal disruption. The Year 2000
Plan also includes communication with critical third parties such as customers,
vendors and other business partners to determine the expected degree of Year
2000 compliance of those parties and to monitor their progress toward Year 2000
readiness. The Year 2000 Plan includes the following phases: 1) assessment, 2)
remediation, 3) testing, and 4) implementation.

         The Company is in the "assessment" phase with regard to its state of
readiness relative to non-IT devices containing embedded circuitry. The Company
is also in the "assessment" phase with regard to third parties with which the
Company has a material relationship. In connection with this assessment, the
Company has made written inquiries of its significant customers and suppliers.
While the Company has not been made aware of any problems that would materially
impact the Company's operations, there can be no assurance that one or more
material third parties will not have Year 2000 problems that materially impact
the Company's business in some fashion. Various agencies of the U.S. government
and military branches of the U.S. armed forces are significant customers of the
Company. As of the date of this report, the Company has received conflicting
data as to the state of any of such customers' Year 2000 readiness. Therefore,
the Company is unsure at this time the extent, if any, that any entity of the
U.S. government with whom the Company has a material relationship will have
internal Year 2000 issues which may materially impact the Company's business.

         The Company is in the "remediation" phase with regard to its IT
systems. As of September 30, 1998, the Company has three subsidiaries using
accounting and manufacturing systems significantly affected by the Year 2000
issue: Simula Safety Systems, Inc., Coach and Car Equipment Corporation, and
Artcraft Industries Corp. The remediation of these systems is approximately 50%
complete and the Company estimates it will complete the conversion to new, Year
2000-compliant, manufacturing and accounting software by December 31, 1998 at
Artcraft Industries Corp., February 28, 1999 at Simula Safety Systems, Inc., and
May 31, 1999 at Coach and Car Equipment Corporation.

         In addition to the internal assessment and remediation efforts being
conducted by the Company pursuant to the Year 2000 Plan as described above, the
Company has engaged the services of a third party consultant to review Year 2000
matters on a subsidiary-by-subsidiary basis. It is anticipated that the
consultant will commence work during the fourth quarter of 1998.

Costs

         The Company has incurred significant costs in connection with its
conversion, beginning in 1996, to the state-of-the-art manufacturing and
accounting systems discussed above. An incidental benefit of this conversion is
that such systems are Year 2000-compliant.

         In addition to the foregoing, the costs associated with the Company's
Year 2000 Plan, including the on-going systems conversions described above, are
expensed as incurred and to date have not been, and are not anticipated to be,
material to the Company's financial position or results of operations.

Risks of Year 2000 Failure

         The failure on any party's part to correct a material Year 2000 problem
could result in an interruption in, or a failure of, certain normal business
activities or operations. Such failures could materially and adversely affect
the Company's results of operations, liquidity and financial condition. The
Company does not yet have a completed contingency plan in the event of a
particular system not being Year 2000 compliant. It is anticipated that a broad
contingency plan, defining areas where detailed contingency plans must be
created, will be completed by December 31, 1998.

         Due to the general uncertainty inherent in the Year 2000 issue,
resulting in large part from the uncertainty of the Year 2000 readiness of
material third party suppliers and customers, the Company is unsure at this time
the extent, if any, that it might be materially adversely impacted by Year 2000
issues.

         Readers are cautioned that forward-looking statements contained in this
Year 2000 discussion should be read in conjunction with the Company's
disclosures under the heading "Forward Looking Information and Risks of the
Business" below.

FORWARD LOOKING INFORMATION AND RISKS OF THE BUSINESS

         Commencing in fiscal 1997, the Company entered large scale production
of the ITS and 16g Seat. Significant investments to transition to high volume
manufacturing for these products were also made in 1997, which affected
earnings. The Company began to realize significant revenues from the
introduction of these products in 1997, which has continued in 1998 and is
anticipated to continue in 1999. The Company's current focus is on controlling
costs and eliminating inefficiencies resulting from the faster than anticipated
rate of growth in its new product lines, principally the 16g Seat, and this
focus should result in a positive impact on earnings.

         In 1997 and the first half of 1998, the Company experienced some parts
and raw materials shortages, vendor delays and quality problems that caused
delays in production and deliveries. The Company has addressed these issues and
believes that it has established an adequate multiple source supplier base that
is industry standard. However, certain components of the Company's products are
proprietary or highly regulated, including certain types of foam, hydrolocks and
woven materials, and shortages of these items could cause disruptions of
production from time to time. In 1998, the Company continues to focus on further
broadening it vendor base and reliability.

         In mid 1998, the Company's 16g Seat operation completed its move into a
new facility and began implementation of new manufacturing procedures and
systems under the guidance of outside experts in the field. While the Company
believes that the new facility and manufacturing procedures will provide the
long-term capabilities needed, the introduction of these new manufacturing
systems is taking longer to implement than was previously estimated and the
estimated cost savings have not yet been realized. The Company believes that
these new systems will properly position these operations to efficiently handle
its growing production volume.


                                       14
<PAGE>   16
                                  SIMULA, INC.

         The complexity of introducing a significant number of new airliner seat
programs into the production flow, and the design and certification issues
related to them has had a negative impact on the Company's 16g Seat operations
and the industry at large. The introduction of these programs in the fourth
quarter of 1998 and in 1999 will continue to impact the efficiency and operating
margins in this segment. The Company believes that when these designs are
completed and introduced into the normal production flow, they will build the
basis for continued strong growth and the achievement of anticipated operating
margins.

         Projected operating results and capital needs will be affected by a
wide variety of factors which could adversely impact revenues, profitability and
cash flows, many of which are beyond the control of the Company. Factors and
risks that may affect results include those described in the Company's
registration statements and periodic reports filed with the U.S. Securities and
Exchange Commission. In addition, other factors include, but are not limited to,
the ultimate realizable value of assets held for sale; manufacturing capacity
and yield; costs of labor, raw materials, supplies, and equipment; reliability
of vendor base; contract mix and shifting production and delivery schedules;
amount of resources committed to independent research and development from time
to time; success in building strategic alliances with large prime contractors
and first tier suppliers to OEMs; the level of orders which are received and can
be shipped and invoiced in a quarter; customer order patterns and seasonality;
the cyclical nature of the industries and markets addressed by the Company's
products; the level and makeup of military expenditures; technological changes;
increased costs attributable to changes in government regulations and
certifications for transport vehicles; competition and competitive pressures on
pricing; and economic conditions in the United States and worldwide markets
served by the Company. The Company's products are incorporated into a variety of
transportation vehicles. A slowdown in demand for new transportation vehicles or
modifications services to transportation vehicles as a result of economic or
other conditions in the United States or worldwide markets served by the Company
and its customers or other broad-based factors could adversely affect the
Company's operating results or financial condition.

PART II - OTHER INFORMATION

ITEM 1.  LEGAL PROCEEDINGS

         On November 3, 1998, the Company filed a complaint in the United States
District Court for the District of Delaware against Autoliv, Inc. seeking
injunctive relief and damages for patent infringement. The Company's complaint
alleges that Autoliv developed, offered, and sold a side impact head protection
device in the United States that infringes the patent that Simula owns for its
Inflatable Tubular Structure ("ITS")(TM). The Company became aware of the
potential infringement in early October 1998 as Autoliv introduced this device
into production automobiles being offered for the first time in the United
States.

         The Company had previously filed a separate lawsuit against Autoliv in
February 1998. This lawsuit alleges certain anti-competitive acts and practices
by Autoliv. This lawsuit is based on unrelated facts and facts arising at an
earlier date than the patent litigation described above. This litigation is
pending.

ITEM 5.  OTHER - STOCK REPURCHASE PLAN

         On November 4, 1998, the Company's Board of Directors approved a Stock
Repurchase Program (the "Program"). Subject to arranging appropriate financing,
the Program is anticipated to become effective during the fourth quarter of 1998
and will extend for one year. Under the Program, the Company may make open
market or negotiated block purchases of the Company's Common Stock up to a
maximum of $5 million in aggregate amount. Shares may be purchased from time to
time depending on market conditions. As of November 9, 1998, the Company was
finalizing negotiations for financing the Program.

Stock Options, at the discretion of the Committee. The type of options granted

Option exercise, the Shares not issued to the Optionee covered by such Option
shall, unless the Plan shall have been terminated, be available for future
grants of Options.


      Subject to the provisions of Section 11 of the Plan, no Employee shall be

      4. Administration of the Plan.


            (a)   Procedure.


                  i) The Plan shall be administered by a Committee of the Board
            consisting solely of two or more outside directors (the
            "Committee"). No member of the Committee shall, during service as an
            administrator, be granted or awarded options, rights, or equity
            securities under the Plan or under any other plan of the Company or
            its affiliates except as permitted under Section 8(d) of the Plan or
            Rule 16b-3 ("Rule 16b-3") under the Securities Exchange Act of 1934,
            as amended (the "Exchange Act"). A quorum of such Committee shall
            consist of a majority of the members of such Committee, or as may be
            otherwise provided in the Company's bylaws. The Plan shall be
            administered by the Committee in accordance with Rule 16b-3.


                  ii) The Committee shall continue to serve until otherwise
            directed by the Board. From time to time the Board may increase the
            size of the Committee and appoint additional members thereof, remove
            members (with or without cause), appoint new members in substitution
            therefor, and fill vacancies however caused; provided, however, that
            at no time may any person serve on the Committee if that person's
            membership would cause the Committee not to satisfy the
            "disinterested administration" requirements of Rule 16b-3.


            (b) Powers of the Committee. Subject to the provisions of the Plan,
      the Committee shall have the authority, in its discretion: (i) to grant
      Incentive Stock Options and Non-Statutory Stock Options in their
      discretion, or pursuant to one or more formulae; (ii) to determine, upon
      review of relevant information and in accordance with Section 2 of the
      Plan, the Fair Market Value of the Common Stock; (iii) to determine the
      exercise price per Share of Options to be granted, which exercise price
      shall be determined in accordance with Section 8(a) of the Plan; (iv) to
      determine the Employees and others to whom, and the time or times at
      which, Options shall be granted and the number of Shares to be represented
      by each Option; (v) to interpret the Plan; (vi) to amend the Plan to the
      extent that such amendment does not require the approval of Shareholders
      and to prescribe, amend and rescind rules and regulations relating to the
      Plan, including modifications to conform the Plan to the requirements of
      the Code and state and federal securities laws, as the same may be amended
      from time to time; (vii) to determine the terms and provisions of each
      Option granted (which need not be identical), including pursuant to
      Section 8(d) and, with the consent of the Optionee thereof, modify or
      amend each Option; (viii) to accelerate or defer (with the consent of the
      Optionee) the exercise date of any Option; (ix) to authorize any person to
      execute on behalf of the Company any instrument required to effectuate the
      grant of an Option previously granted by the Committee; (x) to accept or
      reject the election made by an Optionee pursuant to Section 17 of the
      Plan; and (xi) to make all other determinations deemed necessary or
      advisable for the administration of the Plan.

           (c) Effect of Committee's Decision. All decisions, determinations
      and interpretations of the Committee shall be final and binding on all
      Optionees and any other holders of any Options granted under the Plan.


      5. Eligibility.


           (a) Consistent with the Plan's purposes, Options may be granted only
      to persons as determined by the Committee or executive officers of the
      Company on behalf of the Committee. An individual who has been granted an
      Option may, if he is otherwise eligible, be granted additional Options.
      Incentive Stock Options may be granted only to those Employees who meet
      the requirements applicable under Section 422 of the Code.

           (b) Incentive Stock Options and Non-Statutory Stock Options
      granted to Employees of the Company under the Plan, unless specifically
      provided otherwise in the Stock Option Agreement, will be subject to
      forfeiture until such time as the Optionee has been continuously employed
      by the Company for one year after the date of the grant of the Options,
      and may not be exercised prior to such time. Reload Options will be
      subject to forfeiture until such time as the Optionee has been
      continuously employed by the Company for six (6) months after the date of
      the grant of the Reload Options, or such greater period specified in the
      Stock Option Agreement, and may not be exercised prior to such time. At
      such time as the Optionee has been continuously employed or engaged by the
      Company for the applicable period, the foregoing restrictions shall lapse
      and the Optionee may exercise the Options at any time otherwise consistent
      with the Plan and the Stock Option Agreement. Notwithstanding the
      foregoing, Employees of the Company who become disabled, as described in
      Section 9(c), or who die while employed by the Company or within three (3)
      months thereof, may exercise immediately upon such disability or death
      themselves or through their estates or heirs.

           (c) To the extent that the aggregate Fair Market Value of
      Shares with respect to which Incentive Stock Options granted under the
      Plan and all other plans of the Company and the Parents and Subsidiaries
      of the Company are exercisable for the first time by an Optionee during
      any calendar year exceeds one hundred thousand dollars ($100,000), such
      Options shall be treated for federal income tax purposes as Non-Statutory
      Stock Options.

      6. Shareholder Approval and Effective Date. This Plan was adopted
and became effective on February 26,1992 and grants may be made hereunder as of
the adoption of the Plan. No Option may be granted under the Plan after February
26, 2002 (ten (10) years from the adoption of the Plan); provided, however that
the Plan and all outstanding Options shall remain in effect until such Options
have expired or until such Options are canceled. 

      7. Term of Option. Unless otherwise provided in the Stock Option
Agreement, the term of each Option shall be ten (10) years from the date of
grant thereof. In no case shall the term of any Option exceed ten (10) years
from the date of grant thereof. Notwithstanding the above, in the case of an
Incentive Stock Option granted to an Employee who, at the time the Incentive
Stock Option is granted, owns ten percent (10%) or more of the Common Stock as
such amount is calculated under Section 422(b)(6) of the Code ("Ten Percent
Shareholder"), the term 



                                       4
<PAGE>   5
of the Incentive Stock Option shall be five (5) years from the date of grant
thereof or such shorter time as may be provided in the Stock Option Agreement.

      8. Terms and Conditions.

            (a) Exercise Price. The per Share exercise price for the Shares to
       be issued pursuant to exercise of an Option shall be determined by the
       Committee, but in the case of an Incentive Stock Option shall be no less
       than one hundred percent (100%) of the Fair Market Value per share on the
       date of grant, and in the case of a Non-Statutory Stock Option shall be
       no less than eighty-five percent (85%) of the Fair Market Value per share
       on the date of grant. Notwithstanding the foregoing, in the case of an
       Incentive Stock Option granted to an Employee who, at the time of the
       grant of such Incentive Stock Option, is a Ten Percent Shareholder, the
       per Share exercise price shall be no less than one hundred ten percent
       (110%) of the Fair Market Value per Share on the date of grant.

            (b) Payment. The price of an exercised Option and the Employee's
       portion of any taxes attributable to the delivery of Common Stock under
       the Plan, or portion thereof, shall be paid:

                i) In United States dollars in cash or by check, bank draft or
           money order payable to the order of the Company; or

               ii) At the discretion of the Committee, through the delivery of
           shares of Common Stock with an aggregate Fair Market Value equal to
           the option price and withholding taxes, if any; provided, however,
           that such shares tendered shall have been held by the Optionee a
           minimum of six (6) months; or

              iii) In accordance with applicable Company procedures regarding
           customary "broker" or "cashless" exercises, by directing a third
           party to sell Shares acquired upon exercise of the Option and to
           remit to the Company a sufficient portion of the sale proceeds to pay
           the entire exercise price; or

               iv) In accordance with applicable Company procedures, by
           reducing the number of Shares issuable upon such exercise based on
           the Fair Market Value on the date preceding the date of exercise; or


                v) At the election of the Optionee pursuant to Section 17 and
            with the consent of the Committee pursuant to Section 4(b)(x), by
            the Company's retention of such number of shares of Common Stock
            subject to the exercised Option which have an aggregate Fair Market
            Value on the exercise date equal to the Employee's portion of the
            Company's aggregate federal, state, local and foreign tax
            withholding and FICA and FUTA obligations with respect to income
            generated by the exercise of the Option by Optionee;


               vi) At the election of the Optionee and with the consent of
            the Committee, by the Company's retention of such number of shares
            of Common Stock subject to the exercised Option which have an
            aggregate Fair Market Value 




                                       5
<PAGE>   6
            on the exercise date equal to the Optionee's expected aggregate
            federal, state, local and foreign tax liability, as determined by
            the Optionee and approved by the Committee, with respect to income
            generated by the exercise of the Option by the Optionee;


                vii) By a combination of (i), (ii), (iii), (iv), (v) and (vi)
           above; or


               viii) In the manner provided in subsection (c) below.


            The Committee shall determine acceptable methods for tendering
      Common Stock as payment upon exercise of an Option and may impose such
      limitations and prohibitions on the use of Common Stock to exercise an
      Option as it deems appropriate.


            (c) Financial Assistance to Optionees. The Committee may assist
      Optionees in paying the exercise price of Options granted under this Plan
      in the following manner:


                  i) The extension of a loan to the Optionee by the Company; or


                 ii) Payment by the Optionee of the exercise price in
           installments; or


                iii) A guaranty by the Company of a loan obtained by the
           Optionee from a third party.


            The terms of any loans, installment payments or guarantees,
      including the interest rate and terms of repayment, and collateral
      requirements, if any, shall be determined by the Committee, in its sole
      discretion. Subject to applicable margin requirements, any loans,
      installment payments or guarantees authorized by the Committee pursuant to
      the Plan may be granted without security, but the maximum credit available
      shall not exceed the exercise price for the Shares for which the Option is
      to be exercised, plus any federal and state income tax liability incurred
      in connection with the exercise of the Option.


      9.    Exercise of Option.


            (a) Procedure for Exercise; Rights as a Shareholder. Any Option
      granted hereunder shall be exercisable at such times and under such
      conditions as determined by the Committee, including performance criteria
      with respect to the Company and/or the Optionee, and as shall be
      permissible under the terms of the Plan. Unless otherwise determined by
      the Committee at the time of grant, an Option may be exercised in whole or
      in part. An Option may not be exercised for a fraction of a Share.


            An Option shall be deemed to be exercised when written notice of
      such exercise has been given to the Company in accordance with the terms
      of the Option by the person entitled to exercise the Option and full
      payment for the Shares with respect to which the Option is exercised has
      been received by the company. Full payment may, as authorized by the
      Committee, consist of any consideration and method of payment allowable
      under Section 8(b) of the Plan. Until the issuance (as evidenced by the
      appropriate entry on the books of the Company or of a duly authorized
      transfer agent of the Company) of the 



                                       6
<PAGE>   7
      stock certificate evidencing such Shares, no right to vote or receive
      dividends or any other rights as a stockholder shall exist with respect to
      the Optioned Stock, notwithstanding the exercise of the Option. No
      adjustment will be made for a dividend or other right for which the record
      date is prior to the date the stock certificate is issued, except as
      provided in Section 11 of the Plan.


            Except with respect to Shares not issued to an Optionee pursuant to
      Section 8(b)(iv), the exercise of an Option in any manner shall result in
      a decrease in the number of Shares which thereafter may be available, both
      for purposes of the Plan and for sale under the Option, by the number of
      Shares to which the Option is exercised.


            (b) Termination of Status as an Employee. If an Employee's
      employment by the Company is terminated for cause, then any Option held by
      the Employee shall be immediately canceled upon termination of employment
      and the Employee shall have no further rights with respect to such Option.
      Unless otherwise provided in the Stock Option Agreement (which may reduce
      but not increase the time period described below), if an Employee's
      employment by the Company is terminated for reasons other than cause, and
      does not occur due to death or disability, then the Employee may, with the
      consent of the Board, but only within ten (10) days after the date he
      ceases to be an Employee of the Company, exercise his Option to the extent
      that he was entitled to exercise it at the date of such termination. To
      the extent that he was not entitled to exercise it at the date of such
      termination, or if he does not exercise such Option (which he was entitled
      to exercise) within the time specified herein, the Option shall terminate.


            (c) Disability. Unless otherwise provided in the Stock Option
      Agreement (which may reduce but not increase the time period described
      below), notwithstanding the provisions of Section 9(b) above, in the event
      an Employee is unable to continue his employment with the Company as a
      result of his permanent and total disability (as defined in Section
      22(e)(3) of the Code), he may, but only within twelve (12) months from the
      date of termination, exercise his Option to the extent he was entitled to
      exercise it at the date of such termination. To the extent that he was not
      entitled to exercise the Option at the date of termination, or if he does
      not exercise such Option (which he was entitled to exercise) within the
      time specified herein, the Option shall terminate.


            (d) Death. Unless otherwise provided in the Stock Option Agreement
      (which may reduce but not increase the time period described below), if an
      Employee dies during the term of the Option and is at the time of his
      death an Employee of the Company who shall have been in continuous status
      as an Employee since the date of grant of the Option, the Option may be
      exercised at any time within twelve (12) months following the date of
      death (or such other period of time as is determined by the Board) by the
      Employee's estate or by a person who acquired the right to exercise the
      Option by bequest or inheritance, but only to the extent that an Employee
      was entitled to exercise the Option on the date of death. To the extent
      the Employee was not entitled to exercise the Option on the date of death,
      or if the Employee's estate, or person who acquired the right to exercise
      the Option by bequest or inheritance, does not exercise such Option (which
      he was entitled to exercise) within the time specified herein, the Option
      shall terminate.




                                       7
<PAGE>   8
            (e) Reload Options. Pursuant to applicable Company procedures, if an
      Employee exercises an Option and pays all or a portion of the exercise
      price pursuant to Section 8(b)(ii), (iii) or (iv), such Employee (either
      pursuant to the terms of a Stock Option Agreement or pursuant to the
      exercise of Committee discretion) may be granted a new Option to purchase
      additional Shares equal to the number of Shares retained by the Company or
      Shares not issued to the Optionee pursuant to Section 8(b)(iii) in such
      payment. Such new Option: (i) shall have an exercise price equal to the
      Fair Market Value per Share on the date it is granted; (ii) shall first be
      exercisable six (6) months from its date of grant; and (iii) shall
      terminate on the same date as the termination date of the Options so
      exercised.



      10. Non-Transferability of Options. Unless otherwise specifically provided
in a Stock Option Agreement, an Option may not be sold, pledged, assigned,
hypothecated, transferred or disposed of in any manner other than by will or by
the laws of descent or distribution, and may be exercised, during the lifetime
of the Optionee, only by the Optionee.



      11. Adjustments upon Changes in Capitalization or Merger. Subject to any
required action by the stockholders of the Company, the number of Shares covered
by each outstanding Option, the Section 162(m) Grant Limit, and the number of
Shares which have been authorized for issuance under the Plan but as to which no
Options have yet been granted or which have been returned to the Plan upon
cancellation or expiration of an Option, as well as the price per Share covered
by each such outstanding Option, shall be proportionately adjusted for any
increase or decrease in the number of issued Shares resulting from a stock
split, reverse stock split, stock dividend, combination or reclassification of
the Common Stock, or any other increase or decrease in the number of issued
Shares effected without receipt of consideration by the Company; provided,
however, that conversion of any convertible securities of the Company shall not
be deemed to have been "effected without receipt of consideration." Such
adjustment shall be made by the Committee, whose determination in that respect
shall be final, binding and conclusive. Except as expressly provided herein, no
issuance by the Company of shares of stock of any class, or securities
convertible into shares of stock of any class, shall affect, and no adjustment
by reason thereof shall be made, with respect to the number or price of Shares
subject to an Option.


      In the event of the proposed dissolution or liquidation of the Company,
the Option will terminate immediately prior to the consummation of such proposed
action, unless otherwise provided by the Committee. The Committee may, in the
exercise of its sole discretion in such instances, declare that any Option shall
terminate as of a date fixed by the Committee and give each Optionee the right
to exercise his Option as to all or any part of the Optioned Stock, including
Shares as to which the Option would not otherwise be exercisable.


      In the event of a proposed sale of all or substantially all of the assets
of the Company, or the merger of the Company with or into another corporation,
the Option shall be assumed or an equivalent option shall be substituted by such
successor corporation or a parent or subsidiary of such successor corporation,
unless the Committee determines, in the exercise of its sole discretion and in
lieu of such assumption or substitution, that the Optionee shall have the right
to exercise the option as to all of the Optioned Stock, including Shares as to
which the Option would not otherwise be exercisable.




                                       8

      If the Committee makes an Option fully exercisable in lieu of assumption
or substitution in the event of a merger of sale of assets, the Committee shall
notify the Optionee that the Option shall be fully exercisable for a period of
sixty (60) days from the date of such notice (but not later than the expiration
of the term of the Option under the Option Agreement), and the Option will
terminate upon the expiration of such period.


      12. Time of Granting Options. The date of grant of an Option shall, for
all purposes, be the date on which the Committee (or the executive office
administrator) makes the determination granting such Option. Notice of the
determination shall be given to each Employee to whom an Option is so granted
within a reasonable time after the date of such grant.


      13. Amendment and Termination of the Plan.


            (a) Amendment and Termination. The Committee may amend or terminate
      the Plan from time to time in such respects as the Committee may deem
      advisable; provided, however, that without further shareholder approval,
      the Committee's authority hereunder shall be subject to such restrictions
      as may be required to comply with Section 16(b) of the Exchange Act and
      Section 162(m) of the Code; provided further that the following revisions
      or amendments shall require approval of the Shareholders of the Company,
      to the extent required by law, rule or regulation:


                  i) Any material increase in the number of Shares subject to
            the Plan, other than in connection with an adjustment under Section
            11 of the Plan; or


                  ii) Any material change in the designation of the Employees
            eligible to be granted Options.


            (b) Effect of Amendment or Termination. Any such amendment or
      termination of the Plan shall confer the terms and benefits of the
      amendment on Options already granted; provided that any termination or
      amendment adverse to holders of previously granted Options under the Plan
      shall not affect such previously granted Options, and such Options shall
      remain in full force and effect as if this Plan had not been amended or
      terminated; provided further that (i) any amendment constituting a
      "modification, extension or renewal" under Section 424(h) of the Code and
      the regulations promulgated thereunder shall not apply to Incentive Stock
      Options previously granted that have an exercise price less than the Fair
      Market Value of the Common Stock of the Company on the date of such
      amendment, (ii) any amendment entailing a new measurement date for
      financial accounting purposes shall not apply to Options previously
      granted that have an exercise price less than the Fair Market Value of the
      Common Stock of the Company on the date of such amendment, and (iii) such
      Options shall continue to be governed by the Plan as in effect prior to
      such amendment.


      14. Conditions Upon Issuance of Shares. Shares shall not be issued
pursuant to the exercise of an Option unless the exercise of such Option and the
issuance and delivery of such Shares pursuant thereto shall comply with all
relevant provisions of law, including, without limitation, the Securities Act of
1933, as amended, the Exchange Act, the rules and regulations 



                                       9
<PAGE>   10
promulgated thereunder, and the requirements of any stock exchange upon which
the Shares may then be listed, and shall be further subject to the approval of
counsel for the Company with respect to such compliance.


      As a condition to the exercise of an Option, the Company may require the
person exercising such Option to represent and warrant at the time of any such
exercise that the Shares are being purchased only for investment and without any
present intention to sell or distribute such Shares if, in the opinion of
counsel for the company, such a representation is required by any of the
aforementioned relevant provisions of law.


      Inability of the Company to obtain authority from any regulatory body
having jurisdiction, which authority is deemed by the Company's counsel to be
necessary to the lawful issuance and sale of any Shares hereunder, shall relieve
the Company of any liability in respect of the failure to issue or sell such
Shares as to which such requisite authority shall not have been obtained.

      In the case of an Incentive Stock Option, any Optionee who disposes of
Shares of Common Stock acquired upon the exercise of an Option by sale or
exchange (a) either within two (2) years after the date of the grant of the
Option under which the Common Stock was acquired or (b) within one (1) year
after the acquisition of such Shares of Common Stock shall notify the Company of
such disposition and of the amount realized upon such disposition.

      15. Reservation of Shares. The Company will at all times reserve and keep
available such number of Shares as shall be sufficient to satisfy the
requirements of the Plan.

      16. Option Agreement. Options shall be evidenced by Stock Option
Agreements in such form as the Committee shall approve.

      17. Withholding Taxes. The Committee, or Company executives on behalf of
the Committee, may, in its discretion, condition an Optionee's exercise of an
Option on the Optionee's payment to the Company of the Company's federal, state,
local and foreign tax withholding obligations and FICA and FUTA obligations with
respect to the exercise of such Option by the Optionee (the "Company's
Withholding Obligations"). Subject to Section 4(b)(x) of the Plan and prior to
the Tax Date, the Optionee may make an irrevocable election to have the Company
withhold from those Shares that would otherwise be received upon the exercise of
any Option, a number of Shares having a Fair Market Value equal to the minimum
amount necessary to satisfy the Company's Withholding Obligations.

      An Optionee who is also an officer of the Company must make the above
described election:

            (a) at least six months after the date of grant of the Option
      (except in the event of death or disability); and 

            (b) either:

                        i) six months prior to the Tax Date, or 



                                       10
<PAGE>   11
                ii) prior to the Tax Date and during the period beginning on the
           third business day following the date the Company releases its
           quarterly or annual statement of sales and earnings and ending on the
           twelfth business day following such date.

            18.   Miscellaneous Provisions.

            (a) Plan Expense. Any expense of administering this Plan shall be
      borne by the Company.

            (b) Use of Exercise Proceeds. The payment received from Optionees
      from the exercise of Options shall be used for the general corporate
      purposes of the Company.

            (c) Construction of Plan. The place of administration of the Plan
      shall be in the State of Arizona, and the validity, construction,
      interpretation, administration and effect of the Plan and of its rules and
      regulations, and rights relating to the Plan, shall be determined in
      accordance with the laws of the State of Arizona without regard to
      conflict of law principles and, where applicable, in accordance with the
      Code.

            (d) Taxes. The Company shall be entitled if necessary or desirable
      to pay or withhold the amount of any tax attributable to the delivery of
      Common Stock under the Plan from other amounts payable to the Employee
      after giving the person entitled to receive such Common Stock notice as
      far in advance as practical, and the Company may defer making delivery of
      such Common Stock if any such tax may be pending unless and until
      indemnified to its satisfaction.

            (e) Indemnification. In addition to such other rights of
      indemnification as they may have as members of the Board, the members of
      the Committee shall be indemnified by the Company against all costs and
      expenses reasonably incurred by them in connection with any action, suit
      or proceeding to which they or any of them may be party by reason of any
      action taken or failure to act under or in connection with the Plan or any
      Option, and against all amounts paid by them in settlement thereof
      (provided such settlement is approved by independent legal counsel
      selected by the Company) or paid by them in satisfaction of a judgment in
      any such action, suite or proceeding, except a judgment based upon a
      finding of bad faith; provided that upon the institution of any such
      action, suit or proceeding a Committee member shall, in writing, give the
      Company notice thereof and an opportunity, at its own expense, to handle
      and defend the same before such Committee member undertakes to handle and
      defend it on her or his own behalf.

            (f) Gender. For purposes of this Plan, words used in the masculine
      gender shall include the feminine and neuter, and the singular shall
      include the plural and vice versa, as appropriate.

            (g) No Employment Agreement. The Plan shall not confer upon any
      Optionee any right with respect to continuation of employment with the
      Company, nor 



                                       11
<PAGE>   12
      shall it interfere in any way with his right or the Company's
      right to terminate his employment at any time.

by the Company and held in treasury.

having been exercised in full, or if an exercise pursuant to Section 8(b)(iv)
results in the issuance of a reduced number of Shares in satisfaction of an
Option exercise, the Shares not issued to the Optionee covered by such Option
shall, unless the Plan shall have been terminated, be available for future
grants of Options.

      Subject to the provisions of Section 11 of the Plan, no Employee shall be

      4. Administration of the Plan.

            (a)   Procedure.

                  i) The Plan shall be administered by a Committee of the Board
            consisting solely of two or more outside directors (the
            "Committee"). No member of the Committee shall, during service as an
            administrator, be granted or awarded options, rights, or equity
            securities under the Plan or under any other plan of the Company or
            its affiliates except as permitted under Section 8(d) of the Plan or
            Rule 16b-3 ("Rule 16b-3") under the Securities Exchange Act of 1934,
            as amended (the "Exchange Act"). A quorum of such Committee shall
            consist of a majority of the members of such Committee, or as may be
            otherwise provided in the Company's bylaws. The Plan shall be
            administered by the Committee in accordance with Rule 16b-3.

                  ii) The Committee shall continue to serve until otherwise
            directed by the Board. From time to time the Board may increase the
            size of the Committee and appoint additional members thereof, remove
            members (with or without cause), appoint new members in substitution
            therefor, and fill vacancies however caused; provided, however, that
            at no time may any person serve on the Committee if that person's
            membership would cause the Committee not to satisfy the
            "disinterested administration" requirements of Rule 16b-3.

            (b) Powers of the Committee. Subject to the provisions of the Plan,
      the Committee shall have the authority, in its discretion: (i) to grant
      Incentive Stock Options and Non-Statutory Stock Options in their
      discretion, or pursuant to one or more formulae; (ii) to determine, upon
      review of relevant information and in accordance with Section 2 of the
      Plan, the Fair Market Value of the Common Stock; (iii) to determine the
      exercise price per Share of Options to be granted, which exercise price
      shall be determined in accordance with Section 8(a) of the Plan; (iv) to
      determine the Employees and others to whom, and the time or times at
      which, Options shall be granted and the number of Shares to be represented
      by each Option; (v) to interpret the Plan; (vi) to amend the Plan to the
      extent that such amendment does not require the approval of Shareholders
      and to prescribe, amend and rescind rules and regulations relating to the
      Plan, including modifications to conform the Plan to the requirements of
      the Code and state and federal securities laws, as the same may be amended
      from time to time; (vii) to determine the terms and provisions of each
      Option granted (which need not be identical), including pursuant to
      Section 8(d) and, with the consent of the Optionee thereof, modify or
      amend each Option; (viii) to accelerate or defer (with the consent of the
      Optionee) the exercise date of any Option; (ix) to authorize any person to
      execute on behalf of the Company any instrument required to effectuate the
      grant of an Option previously granted by the Committee; (x) to accept or
      reject the election made by an Optionee pursuant to Section 17 of the
      Plan; and (xi) to make all other determinations deemed necessary or
      advisable for the administration of the Plan.



                                       3
<PAGE>   4
            (c) Effect of Committee's Decision. All decisions, determinations
      and interpretations of the Committee shall be final and binding on all
      Optionees and any other holders of any Options granted under the Plan.

      5.    Eligibility.

            (a) Consistent with the Plan's purposes, Options may be granted only
      to persons as determined by the Committee or executive officers of the
      Company on behalf of the Committee. An individual who has been granted an
      Option may, if he is otherwise eligible, be granted additional Options.
      Incentive Stock Options may be granted only to those Employees who meet
      the requirements applicable under Section 422 of the Code.

            (b) Incentive Stock Options and Non-Statutory Stock Options granted
      to Employees and outside directors of the Company under the Plan, unless
      specifically provided otherwise in the Stock Option Agreement, will be
      subject to forfeiture until such time as the Optionee has been
      continuously employed by the Company for one year after the date of the
      grant of the Options (or in the case of an outside director, served one
      year thereafter), and may not be exercised prior to such time. Reload
      Options will be subject to forfeiture until such time as the Optionee has
      been continuously employed by the Company for six (6) months after the
      date of the grant of the Reload Options (or in the case of an outside
      director, served six (6) months thereafter), or such greater period
      specified in the Stock Option Agreement, and may not be exercised prior to
      such time. At such time as the Optionee has been continuously employed or
      engaged by the Company for the applicable period, the foregoing
      restrictions shall lapse and the Optionee may exercise the Options at any
      time otherwise consistent with the Plan and the Stock Option Agreement.
      Notwithstanding the foregoing, Employees or outside directors of the
      Company who become disabled, as described in Section 9(c), or who die
      while employed by the Company or within three (3) months thereof, may
      exercise immediately upon such disability or death themselves or through
      their estates or heirs.

            (c) To the extent that the aggregate Fair Market Value of Shares
      with respect to which Incentive Stock Options granted under the Plan and
      all other plans of the Company and the Parents and Subsidiaries of the
      Company are exercisable for the first time by an Optionee during any
      calendar year exceeds one hundred thousand dollars ($100,000), such
      Options shall be treated for federal income tax purposes as Non-Statutory
      Stock Options.

      6. Shareholder Approval and Effective Date. This Plan was first
adopted in June of 1994 and was last materially amended by Company shareholders
on June 12, 1997, and grants may be made hereunder as of the initial adoption of
the Plan. No Option may be granted under the Plan after June 12, 2007 (ten (10)
years from the last shareholder approval of a material amendment to the Plan);
provided, however that the Plan and all outstanding Options shall remain in
effect until such Options have expired or until such Options are canceled.

      7. Term of Option. Unless otherwise provided in the Stock Option
Agreement, the term of each Option shall be ten (10) years from the date of
grant thereof. In no case shall the term of any Option exceed ten (10) years
from the date of grant thereof. Notwithstanding the



                                       4
<PAGE>   5
above, in the case of an Incentive Stock Option granted to an Employee who, at
the time the Incentive Stock Option is granted, owns ten percent (10%) or more
of the Common Stock as such amount is calculated under Section 422(b)(6) of the
Code ("Ten Percent Shareholder"), the term of the Incentive Stock Option shall
be five (5) years from the date of grant thereof or such shorter time as may be
provided in the Stock Option Agreement.

      8. Terms and Conditions.

                  (a) Exercise Price. The per Share exercise price for the
      Shares to be issued pursuant to exercise of an Option shall be determined
      by the Committee, but in the case of an Incentive Stock Option shall be no
      less than one hundred percent (100%) of the Fair Market Value per share on
      the date of grant, and in the case of a Non-Statutory Stock Option shall
      be no less than eighty-five percent (85%) of the Fair Market Value per
      share on the date of grant. Notwithstanding the foregoing, in the case of
      an Incentive Stock Option granted to an Employee who, at the time of the
      grant of such Incentive Stock Option, is a Ten Percent Shareholder, the
      per Share exercise price shall be no less than one hundred ten percent
      (110%) of the Fair Market Value per Share on the date of grant.

                  (b) Payment. The price of an exercised Option and the
      Employee's portion of any taxes attributable to the delivery of Common
      Stock under the Plan, or portion thereof, shall be paid:

                        i) In United States dollars in cash or by check, bank
            draft or money order payable to the order of the Company; or

                        ii) At the discretion of the Committee, through the
            delivery of shares of Common Stock with an aggregate Fair Market
            Value equal to the option price and withholding taxes, if any;
            provided, however, that such shares tendered shall have been held by
            the Optionee a minimum of six (6) months; or

                        iii) In accordance with applicable Company procedures
            regarding customary "broker" or "cashless" exercises, by directing a
            third party to sell Shares acquired upon exercise of the Option and
            to remit to the Company a sufficient portion of the sale proceeds to
            pay the entire exercise price; or

                        iv) In accordance with applicable Company procedures, by
            reducing the number of Shares issuable upon such exercise based on
            the Fair Market Value on the date preceding the date of exercise; or

                        v) At the election of the Optionee pursuant to Section
            17 and with the consent of the Committee pursuant to Section
            4(b)(x), by the Company's retention of such number of shares of
            Common Stock subject to the exercised Option which have an aggregate
            Fair Market Value on the exercise date equal to the Employee's
            portion of the Company's aggregate federal, state, local and foreign
            tax withholding and FICA and FUTA obligations with respect to income
            generated by the exercise of the Option by Optionee;




                                       5
<PAGE>   6
                  vi) At the election of the Optionee and with the consent of
            the Committee, by the Company's retention of such number of shares
            of Common Stock subject to the exercised Option which have an
            aggregate Fair Market Value on the exercise date equal to the
            Optionee's expected aggregate federal, state, local and foreign tax
            liability, as determined by the Optionee and approved by the
            Committee, with respect to income generated by the exercise of the
            Option by the Optionee;

                  vii) By a combination of (i), (ii), (iii), (iv), (v) and
            (vi) above; or

                  viii) In the manner provided in subsection (c) below.

            The Committee shall determine acceptable methods for tendering
      Common Stock as payment upon exercise of an Option and may impose such
      limitations and prohibitions on the use of Common Stock to exercise an
      Option as it deems appropriate.

            (c) Financial Assistance to Optionees. The Committee may assist
      Optionees in paying the exercise price of Options granted under this Plan
      in the following manner:

                  i) The extension of a loan to the Optionee by the Company; or

                  ii) Payment by the Optionee of the exercise price in
            installments; or

                  iii) A guaranty by the Company of a loan obtained by the
            Optionee from a third party.

            The terms of any loans, installment payments or guarantees,
      including the interest rate and terms of repayment, and collateral
      requirements, if any, shall be determined by the Committee, in its sole
      discretion. Subject to applicable margin requirements, any loans,
      installment payments or guarantees authorized by the Committee pursuant to
      the Plan may be granted without security, but the maximum credit available
      shall not exceed the exercise price for the Shares for which the Option is
      to be exercised, plus any federal and state income tax liability incurred
      in connection with the exercise of the Option.

            (d) Outside Directors Options. Each outside director of the Company
      (that is, each director who is not also an Employee of the Company and is
      not affiliated with any entity directly or indirectly owning five percent
      (5%) or more of any class of stock of the Company) shall be automatically
      granted Non-Statutory Stock Options for (i) fifteen thousand (15,000)
      Shares as of the effective date of this Plan (or, as of the date of their
      appointment or election to the Board for individuals that are not members
      as of the effective date of the Plan) and, (ii) one thousand five hundred
      (1,500) Shares on or about the date of each successive Annual Meeting of
      the Shareholders of the Company, commencing with the Annual Meeting in
      1996. Such initial and annually awarded Options shall be granted on the
      terms and conditions and limitations applicable generally to the grant of
      Non-Statutory Options under this Plan. The exercise price of such Options
      shall be one hundred percent (100%) of the Fair Market Value on the date
      of grant. The provisions of this Plan regarding formula awards to outside
      directors shall not be



                                       6
<PAGE>   7
      amended more than once every six (6) months, other then to comport with
      changes in the Internal Revenue Code, the Employee Retirement Income
      Security Act, or the rules thereunder.

      9.    Exercise of Option.

            (a) Procedure for Exercise; Rights as a Shareholder. Any Option
      granted hereunder shall be exercisable at such times and under such
      conditions as determined by the Committee, including performance criteria
      with respect to the Company and/or the Optionee, and as shall be
      permissible under the terms of the Plan. Unless otherwise determined by
      the Committee at the time of grant, an Option may be exercised in whole or
      in part. An Option may not be exercised for a fraction of a Share.

            An Option shall be deemed to be exercised when written notice of
      such exercise has been given to the Company in accordance with the terms
      of the Option by the person entitled to exercise the Option and full
      payment for the Shares with respect to which the Option is exercised has
      been received by the company. Full payment may, as authorized by the
      Committee, consist of any consideration and method of payment allowable
      under Section 8(b) of the Plan. Until the issuance (as evidenced by the
      appropriate entry on the books of the Company or of a duly authorized
      transfer agent of the Company) of the stock certificate evidencing such
      Shares, no right to vote or receive dividends or any other rights as a
      stockholder shall exist with respect to the Optioned Stock,
      notwithstanding the exercise of the Option. No adjustment will be made for
      a dividend or other right for which the record date is prior to the date
      the stock certificate is issued, except as provided in Section 11 of the
      Plan.

            Except with respect to Shares not issued to an Optionee pursuant to
      Section 8(b)(iv), the exercise of an Option in any manner shall result in
      a decrease in the number of Shares which thereafter may be available, both
      for purposes of the Plan and for sale under the Option, by the number of
      Shares to which the Option is exercised.

            (b) Termination of Status as an Employee. If an Employee's
      employment by the Company is terminated for cause, then any Option held by
      the Employee shall be immediately canceled upon termination of employment
      and the Employee shall have no further rights with respect to such Option.
      Unless otherwise provided in the Stock Option Agreement, if an Employee's
      employment by the Company is terminated for reasons other than cause, and
      does not occur due to death or disability, then the Employee may exercise
      his Option at any time during the term of the Option to the extent that he
      was entitled to exercise it at the date of such termination, provided that
      any exercise of an Incentive Stock Option after the period ending three
      (3) months following an Employee's termination shall be treated as the
      exercise of a Non-Statutory Stock Option. To the extent that he was not
      entitled to exercise the Option at the date of such termination, the
      Option shall terminate.

            (c) Disability. In the event an Employee is unable to continue his
      employment with the Company as a result of his permanent and total
      disability (as defined in Section 22(e)(3) of the Code), he may exercise
      his Option at any time during the term


                                       7
<PAGE>   8
      of the Option to the extent he was entitled to exercise it at the date of
      such termination, provided that any exercise of an Incentive Stock Option
      after the period ending one (1) year following an Employee's termination
      shall be treated as the exercise of a Non-Statutory Stock Option. To the
      extent that he was not entitled to exercise the Option at the date of
      termination, the Option shall terminate.

             (d) Death. If an Employee dies during the term of the Option, the
      Option may be exercised at any time following the date of death during the
      term of the Option by the Employee's estate or by a person who acquired
      the right to exercise the Option by bequest or inheritance, but only to
      the extent that an Employee was entitled to exercise the Option on the
      date of death. To the extent the Employee was not entitled to exercise the
      Option on the date of death, the Option shall terminate.

            (e) Reload Options. Pursuant to applicable Company procedures, if an
      Employee exercises an Option and pays all or a portion of the exercise
      price pursuant to Section 8(b)(ii), (iii) or (iv), such Employee (either
      pursuant to the terms of a Stock Option Agreement or pursuant to the
      exercise of Committee discretion) may be granted a new Option to purchase
      additional Shares equal to the number of Shares retained by the Company or
      Shares not issued to the Optionee pursuant to Section 8(b)(iii) in such
      payment. Such new Option: (i) shall have an exercise price equal to the
      Fair Market Value per Share on the date it is granted; (ii) shall first be
      exercisable six (6) months from its date of grant; and (iii) shall
      terminate on the same date as the termination date of the Options so
      exercised.

      10. Non-Transferability of Options. Unless otherwise specifically provided
in a Stock Option Agreement, an Option may not be sold, pledged, assigned,
hypothecated, transferred or disposed of in any manner other than by will or by
the laws of descent or distribution, and may be exercised, during the lifetime
of the Optionee, only by the Optionee.

      11. Adjustments upon Changes in Capitalization or Merger. Subject to any
required action by the stockholders of the Company, the number of Shares covered
by each outstanding Option, the Section 162(m) Grant Limit, and the number of
Shares which have been authorized for issuance under the Plan but as to which no
Options have yet been granted or which have been returned to the Plan upon
cancellation or expiration of an Option, as well as the price per Share covered
by each such outstanding Option, shall be proportionately adjusted for any
increase or decrease in the number of issued Shares resulting from a stock
split, reverse stock split, stock dividend, combination or reclassification of
the Common Stock, or any other increase or decrease in the number of issued
Shares effected without receipt of consideration by the Company; provided,
however, that conversion of any convertible securities of the Company shall not
be deemed to have been "effected without receipt of consideration." Such
adjustment shall be made by the Committee, whose determination in that respect
shall be final, binding and conclusive. Except as expressly provided herein, no
issuance by the Company of shares of stock of any class, or securities
convertible into shares of stock of any class, shall affect, and no adjustment
by reason thereof shall be made, with respect to the number or price of Shares
subject to an Option.

      In the event of the proposed dissolution or liquidation of the Company,
the Option will terminate immediately prior to the consummation of such proposed
action, unless otherwise



                                       8
<PAGE>   9
provided by the Committee. The Committee may, in the exercise of its sole
discretion in such instances, declare that any Option shall terminate as of a
date fixed by the Committee and give each Optionee the right to exercise his
Option as to all or any part of the Optioned Stock, including Shares as to which
the Option would not otherwise be exercisable.

      In the event of a proposed sale of all or substantially all of the assets
of the Company, or the merger of the Company with or into another corporation,
the Option shall be assumed or an equivalent option shall be substituted by such
successor corporation or a parent or subsidiary of such successor corporation,
unless the Committee determines, in the exercise of its sole discretion and in
lieu of such assumption or substitution, that the Optionee shall have the right
to exercise the option as to all of the Optioned Stock, including Shares as to
which the Option would not otherwise be exercisable.

      If the Committee makes an Option fully exercisable in lieu of assumption
or substitution in the event of a merger of sale of assets, the Committee shall
notify the Optionee that the Option shall be fully exercisable for a period of
sixty (60) days from the date of such notice (but not later than the expiration
of the term of the Option under the Option Agreement), and the Option will
terminate upon the expiration of such period.

      12. Time of Granting Options. The date of grant of an Option shall, for
all purposes, be the date on which the Committee (or the executive office
administrator) makes the determination granting such Option. Notice of the
determination shall be given to each Employee to whom an Option is so granted
within a reasonable time after the date of such grant.

      13. Amendment and Termination of the Plan.

            (a) Amendment and Termination. The Committee may amend or terminate
      the Plan from time to time in such respects as the Committee may deem
      advisable; provided, however, that without further shareholder approval,
      the Committee's authority hereunder shall be subject to such restrictions
      as may be required to comply with Section 16(b) of the Exchange Act and
      Section 162(m) of the Code; provided further that the following revisions
      or amendments shall require approval of the Shareholders of the Company,
      to the extent required by law, rule or regulation:

                  i) Any material increase in the number of Shares subject to
            the Plan, other than in connection with an adjustment under Section
            11 of the Plan; or

                  ii) Any material change in the designation of the Employees
            eligible to be granted Options.

            (b) Effect of Amendment or Termination. Any such amendment or
      termination of the Plan shall confer the terms and benefits of the
      amendment on Options already granted, provided that any termination or
      amendment adverse to holders of previously granted Options under the Plan
      shall not affect such previously granted Options, and such Options shall
      remain in full force and effect as if this Plan had not been amended or
      terminated; provided further that (i) any amendment constituting a



                                       9
<PAGE>   10
      "modification, extension or renewal" under Section 424(h) of the Code and
      the regulations promulgated thereunder shall not apply to Incentive Stock
      Options previously granted that have an exercise price less than the Fair
      Market Value of the Common Stock of the Company on the date of such
      amendment, (ii) any amendment entailing a new measurement date for
      financial accounting purposes shall not apply to Options previously
      granted that have an exercise price less than the Fair Market Value of the
      Common Stock of the Company on the date of such amendment, and (iii) such
      Options shall continue to be governed by the Plan as in effect prior to
      such amendment.

      14. Conditions Upon Issuance of Shares. Shares shall not be issued
pursuant to the exercise of an Option unless the exercise of such Option and the
issuance and delivery of such Shares pursuant thereto shall comply with all
relevant provisions of law, including, without limitation, the Securities Act of
1933, as amended, the Exchange Act, the rules and regulations promulgated
thereunder, and the requirements of any stock exchange upon which the Shares may
then be listed, and shall be further subject to the approval of counsel for the
Company with respect to such compliance.

      As a condition to the exercise of an Option, the Company may require the
person exercising such Option to represent and warrant at the time of any such
exercise that the Shares are being purchased only for investment and without any
present intention to sell or distribute such Shares if, in the opinion of
counsel for the company, such a representation is required by any of the
aforementioned relevant provisions of law.

      Inability of the Company to obtain authority from any regulatory body
having jurisdiction, which authority is deemed by the Company's counsel to be
necessary to the lawful issuance and sale of any Shares hereunder, shall relieve
the Company of any liability in respect of the failure to issue or sell such
Shares as to which such requisite authority shall not have been obtained.

      In the case of an Incentive Stock Option, any Optionee who disposes of
Shares of Common Stock acquired upon the exercise of an Option by sale or
exchange (a) either within two (2) years after the date of the grant of the
Option under which the Common Stock was acquired or (b) within one (1) year
after the acquisition of such Shares of Common Stock shall notify the Company of
such disposition and of the amount realized upon such disposition.

      15. Reservation of Shares. The Company will at all times reserve and keep
available such number of Shares as shall be sufficient to satisfy the
requirements of the Plan.

      16. Option Agreement. Options shall be evidenced by Stock Option
Agreements in such form as the Committee shall approve.

      17. Withholding Taxes. The Committee, or Company executives on behalf of
the Committee, may, in its discretion, condition an Optionee's exercise of an
Option on the Optionee's payment to the Company of the Company's federal, state,
local and foreign tax withholding obligations and FICA and FUTA obligations with
respect to the exercise of such Option by the Optionee (the "Company's
Withholding Obligations"). Subject to Section 4(b)(x) of the Plan and prior to
the Tax Date, the Optionee may make an irrevocable election to have the



                                       10
<PAGE>   11
Company withhold from those Shares that would otherwise be received upon the
exercise of any Option, a number of Shares having a Fair Market Value equal to
the minimum amount necessary to satisfy the Company's Withholding Obligations.

      An Optionee who is also an officer of the Company must make the above
described election:

            (a) at least six months after the date of grant of the Option
      (except in the event of death or disability); and

            (b) either:

                        i) six months prior to the Tax Date, or

                        ii) prior to the Tax Date and during the period
            beginning on the third business day following the date the Company
            releases its quarterly or annual statement of sales and earnings and
            ending on the twelfth business day following such date.

            18.   Miscellaneous Provisions.

            (a) Plan Expense. Any expense of administering this Plan shall be
      borne by the Company.

            (b) Use of Exercise Proceeds. The payment received from Optionees
      from the exercise of Options shall be used for the general corporate
      purposes of the Company.

            (c) Construction of Plan. The place of administration of the Plan
      shall be in the State of Arizona, and the validity, construction,
      interpretation, administration and effect of the Plan and of its rules and
      regulations, and rights relating to the Plan, shall be determined in
      accordance with the laws of the State of Arizona without regard to
      conflict of law principles and, where applicable, in accordance with the
      Code.

            (d) Taxes. The Company shall be entitled if necessary or desirable
      to pay or withhold the amount of any tax attributable to the delivery of
      Common Stock under the Plan from other amounts payable to the Employee
      after giving the person entitled to receive such Common Stock notice as
      far in advance as practical, and the Company may defer making delivery of
      such Common Stock if any such tax may be pending unless and until
      indemnified to its satisfaction.

            (e) Indemnification. In addition to such other rights of
      indemnification as they may have as members of the Board, the members of
      the Committee shall be indemnified by the Company against all costs and
      expenses reasonably incurred by them in connection with any action, suit
      or proceeding to which they or any of them may be party by reason of any
      action taken or failure to act under or in connection with the Plan or any
      Option, and against all amounts paid by them in settlement thereof
      (provided such settlement is approved by independent legal counsel
      selected by the Company) or paid by



                                       11
<PAGE>   12
      them in satisfaction of a judgment in any such action, suite or
      proceeding, except a judgment based upon a finding of bad faith; provided
      that upon the institution of any such action, suit or proceeding a
      Committee member shall, in writing, give the Company notice thereof and an
      opportunity, at its own expense, to handle and defend the same before such
      Committee member undertakes to handle and defend it on her or his own
      behalf.

            (f) Gender. For purposes of this Plan, words used in the masculine
      gender shall include the feminine and neuter, and the singular shall
      include the plural and vice versa, as appropriate.

            (g) No Employment Agreement. The Plan shall not confer upon any
      Optionee any right with respect to continuation of employment with the
      Company, nor shall it interfere in any way with his right or the Company's
      right to terminate his employment at any time.

                                   ARTICLE 2.

                                     THE RLC

         2.1 RLC Commitment. Each Bank agrees, severally but not jointly, to
loan to or for the benefit of Borrower, and Borrower shall be entitled to draw
upon and borrow, in the manner and upon the terms and conditions contained in
this Senior Credit Agreement, an amount that shall not exceed that Bank's Pro
Rata Share of the RLC Commitment.

         2.2 Revolving Line.

                  (a) Subject to the terms and conditions set forth in this
         Senior Credit Agreement, each Bank shall provide to Borrower a
         revolving line of credit (each, a "RLC"), against which a Bank shall
         fund its Pro Rata Share of each RLC Advance to be made to Borrower,
         repaid by Borrower, and readvanced to Borrower, as Borrower may
         request, and the Issuing Bank shall issue such Letters of Credit as
         Borrower shall request, which may be terminated or repaid by Borrower
         and reissued provided that (i) there is no Event of Default under any
         provision of this Senior Credit Agreement, (ii) no RLC Advance shall be
         made or Letter of Credit issued that would cause the RLC Balance to
         exceed the RLC Commitment, (iii) no Bank shall be obligated under any
         circumstances to fund an RLC Advance in excess of that Bank's Pro Rata
         Share of the requested RLC Advance, (iv) the aggregate amount of a
         Bank's funding of the RLC Balance at any one time outstanding shall not
         exceed its Pro Rata Share of the RLC Commitment, and (v) no Letter of
         Credit shall be issued with a Stated Expiry Date later than the RLC
         Maturity Date. The Banks shall not be obligated to fund their Pro Rata
         Share of any RLC Advance if, after giving effect thereto, any of the
         foregoing limitations would be exceeded.

                  (b) The failure of any Bank to fund its Pro Rata Share of an
         RLC Advance in accordance with its Pro Rata Share of the RLC Commitment
         shall not relieve any other Bank of its several obligations hereunder,
         but no Bank shall be liable with respect to the obligation of any other
         Bank hereunder.

                  (c) RLC Advances may be made for the purpose of providing to
         Borrower working capital financing or in connection with a Disbursement
         under a Letter of Credit.

         2.3 RLC Notes. The RLC of each Bank shall be evidenced by an RLC Note
and shall bear interest and be payable to the order of such Bank upon the terms
and conditions contained therein. The aggregate amount funded by a Bank under
its RLC Note less all repayments of principal thereof shall be the principal
amount owing and unpaid on its RLC Note and its RLC. The principal amount funded
by a Bank and all principal payments and prepayments thereof may be noted by
such Bank on a schedule attached to its RLC Note and shall be entered by the
Bank


                                      -18-
<PAGE>   25

on its ledgers and computer records; provided that the failure of the Bank to
make such notations or entries shall not affect the principal amount owing and
unpaid on its RLC Note. The entries made in the ordinary course of business by a
Bank on its ledgers and computer records and any notations made in the ordinary
course of business by a Bank on any such schedule annexed to its RLC Note shall
be presumed to be accurate until the contrary is established. If requested,
Borrower shall confirm in writing to the Administrative Agent each RLC Advance.

         2.4 RLC. The RLC shall bear interest and be payable to the Banks upon
the terms and conditions contained therein, which include the following
provisions:

                  (a) Interest shall accrue:

                           (i) Except to the extent that an RLC Advance bears
                  interest at the LIBOR Based Rate, on the unpaid principal of
                  each RLC Advance at the Variable Rate.

                           (ii) To the extent Borrower shall elect and to the
                  extent not otherwise provided herein, on the unpaid principal
                  of an RLC Advance at the LIBOR Based Rate.

                  (b) All interest shall be computed on the basis of a 360-day
         year and accrue on a daily basis for the actual number of days elapsed.
         All accrued interest shall be due and payable on each Payment Date.

                  (c) The entire unpaid principal balance, all accrued and
         unpaid interest, and all other amounts payable under the RLC Note shall
         be due and payable in full on the RLC Maturity Date.

                  (d) Each request for an RLC Advance shall, in addition to
         complying with the other requirements in this Senior Credit Agreement,
         (i) specify the date and amount of the requested RLC Advance, (ii)
         specify whether the RLC Advance shall be an RLC Advance that bears
         interest at the Variable Rate or shall be an RLC Advance that bears
         interest at the LIBOR Based Rate, and (iii), if the RLC Advance is to
         bear interest at the LIBOR Based Rate, (A) specify the Interest Period,
         (B) be delivered to Administrative Agent before 9:00 a.m. (Phoenix,
         Arizona local time) at least two (2) Business Days prior to the date of
         the requested RLC Advance, and (C) be in a minimum amount of
         $1,000,000.00 with integral multiples of $500,000.00 in excess thereof.
         Any RLC Advance not complying with the foregoing requirements for an
         RLC Advance bearing interest at the LIBOR Based Rate shall bear
         interest at the Variable Rate.

                  (e) After receiving a request for an RLC Advance in the manner
         provided herein, the Administrative Agent shall promptly, before 11:30
         a.m. (Phoenix, Arizona local time) on the date an RLC Advance is
         requested, notify


                                      -19-
<PAGE>   26

         each Bank by telephone (confirmed promptly in writing), telefacsimile
         or cable of the terms of such request and such Bank's Pro Rata Share of
         the requested RLC Advance. Each Bank shall, before 1:00 p.m. (Phoenix,
         Arizona local time) on the date an RLC Advance is to be made as
         specified in a request for an RLC Advance, deposit with the
         Administrative Agent such Bank's Pro Rata Share of the requested RLC
         Advance in immediately available funds. Upon fulfillment of all
         applicable conditions set forth herein and after receipt by the
         Administrative Agent of such funds, the Administrative Agent shall pay
         or deliver all funds so received to the order of Borrower at the
         principal office of the Administrative Agent. The failure of any Bank
         to fund its Pro Rata Share of any RLC Advance required of it hereunder
         shall not relieve any other Bank of its obligation to fund its Pro Rata
         Share of any RLC Advance hereunder. If any Bank fails to fund its Pro
         Rata Share of the requested RLC Advance and if all conditions to such
         RLC Advance have apparently been satisfied, the Administrative Agent
         will make available to Borrower the funds received by it from the other
         Bank. Neither the Administrative Agent nor any Bank shall be
         responsible for the performance by any other Bank of its obligations
         hereunder.

                  Unless the Administrative Agent shall have received notice
         from a Bank prior to the date of any RLC Advance that such Bank will
         not make available to the Administrative Agent such Bank's Pro Rata
         Share of the requested RLC Advance, the Administrative Agent may assume
         that such Bank has made such amount available to the Administrative
         Agent on the date of such RLC Advance in accordance with this Section
         and the Administrative Agent may, in reliance upon such assumption,
         make available a corresponding amount to or on behalf of Borrower on
         such date. If and to the extent any Bank shall not have so made its Pro
         Rata Share of the requested RLC Advance available to the Administrative
         Agent (the "Principal Shortfall Amount"), Borrower agrees to repay the
         Principal Shortfall Amount to the Administrative Agent forthwith on
         demand, together with interest thereon for each day from (and
         including) the date such amount is made available to or on behalf of
         Borrower to (but excluding) the date such amount is repaid to the
         Administrative Agent, at the rate per annum equal to the rate otherwise
         applicable to the RLC Advance in question.

                  (f) If Borrower desires that a LIBOR Based Rate RLC Advance
         continue to bear interest at the LIBOR Based Rate after the end of an
         existing Interest Period, Borrower shall deliver to the Administrative
         Agent a notice making such election and specifying the new Interest
         Period. If Borrower does not deliver such notice within such time, then
         after the existing Interest Period the LIBOR Based Rate RLC Advance
         shall become a Variable Rate RLC Advance and shall bear interest at the
         Variable Rate.

                  (g) Borrower may upon written notice to and received by the
         Administrative Agent not later than 9:00 a.m. (Phoenix, Arizona local
         time) (i) on


                                      -20-
<PAGE>   27

         the second Business Day, in the case of any conversion of a Variable
         Rate RLC Advance into a LIBOR Based Rate RLC Advance and (ii) on the
         first Business Day in the case of any conversion of a LIBOR Based Rate
         RLC Advance into a Variable Rate RLC Advance, prior to the date of the
         proposed conversion, convert any RLC Advance of one type into an RLC
         Advance of the other type, provided, however, that any conversion of a
         LIBOR Based Rate RLC Advance (A) shall only be made on the last day of
         the applicable Interest Period except as otherwise provided herein, and
         (B) shall be made only as to an RLC Advance in a minimum amount of
         $1,000,000.00 with integral multiples of $500,000.00 in excess thereof.
         Each such notice of a conversion shall specify the date of such
         conversion and the RLC Advance(s) to be converted. After receiving any
         such notice, the Administrative Agent shall promptly notify each Bank
         by telephone, telefacsimile or cable and deliver a copy thereof to each
         Bank.

                  (h) Each request for an RLC Advance as well as each election
         by the Borrower that an RLC Advance continue to bear interest at the
         LIBOR Based Rate after the end of an existing Interest Period and each
         conversion request shall be irrevocable and binding on Borrower once
         the request is received by the Administrative Agent and the
         Administrative Agent notifies the Banks of the request. Prior to the
         Administrative Agent's notice of the request to the Banks, Borrower may
         revoke the request. Borrower shall indemnify each Bank against any
         cost, loss or expense incurred by any Bank as a result of Borrower's
         failure to fulfill, on or before the date specified for an RLC Advance
         in any request for an RLC Advance, the conditions to such RLC Advance
         set forth herein, including any cost, loss or expense incurred by
         reason of the liquidation or reemployment of deposits or other funds
         acquired by a Bank to fund such RLC Advance when such RLC Advance, as a
         result of such failure, is not made on the date so specified.

                  (i) No RLC Advance shall be requested by Borrower to bear a
         LIBOR Based Rate, whether pursuant to a request for an RLC Advance or a
         conversion hereunder, so long as there shall have occurred an Event of
         Default and such Event of Default is continuing.

                  (j) Nothing herein shall be deemed to relieve any Bank from
         its obligation to fulfill its Pro Rata Share of the RLC Commitment
         hereunder or to prejudice any right which the Administrative Agent or
         the Borrower may have against any Bank as a result of any default by
         such Bank hereunder.

                  (k) Upon an Event of Default, including failure to pay upon
         final maturity, the Banks, at their option, may also, if permitted
         under applicable law, do one or both of the following: (a) increase the
         applicable interest rate to the Default Rate, and/or (b) add any unpaid
         accrued interest to principal and such sum will bear interest therefrom
         until paid at the rate provided herein (including any


                                      -21-
<PAGE>   28

         increased rate). The interest rate will not exceed the maximum rate
         permitted by applicable law.

         2.5 Excess Balance Repayment. There shall be due and payable from
Borrower to the Banks, and Borrower shall immediately repay to the Banks,
without notice or demand, from time to time, any amount by which the RLC Balance
exceeds the RLC Commitment.

         2.6 Reduction of RLC Commitment. Borrower shall have the right at any
time upon at least seven days' prior written notice to the Administrative Agent
to reduce the aggregate amount of the RLC Commitment; provided, that the amount
of each such reduction shall be in a minimum aggregate amount of $1,000,000.00
or an integral aggregate multiple of $100,000.00 in excess thereof and that no
such reduction shall reduce (i) the amount of the RLC Commitment to less than
the RLC Balance, or (ii) the amount of a Bank's Pro Rata Share of the RLC
Commitment to less than the amount of the RLC Balance funded by such Bank. Any
reduction in the aggregate amount of the RLC Commitment shall reduce each Bank's
share of the RLC Commitment by its Pro Rata Share of the aggregate amount of
such reduction. The Administrative Agent shall promptly notify each Bank of any
such notice of reduction received from the Borrower. Any reduction in the RLC
Commitment may not be reinstated without the mutual prior consent of the
Borrower and the Banks.

         2.7 Conditions. The Banks shall have no obligation to fund their Pro
Rata Shares of any RLC Advance unless and until all of the conditions and
requirements of this Senior Credit Agreement are fully satisfied. However, the
Banks in their sole and absolute discretion may elect to make one or more RLC
Advances prior to full satisfaction of one or more such conditions and/or
requirements. Notwithstanding that such an RLC Advance or RLC Advances are made,
such unsatisfied conditions and/or requirements shall not be waived or released
thereby. Borrower shall be and continue to be obligated to fully satisfy such
conditions and requirements, and the Banks, at any time, in their sole and
absolute discretion, may stop making RLC Advances until all conditions and
requirements are fully satisfied.

         2.8 Other RLC Advances. The Administrative Agent, at the direction of
the Banks, after giving written notice to Borrower, from time to time, may make
RLC Advances in any amount in payment of (i) insurance premiums, taxes,
assessments, liens or encumbrances existing against Borrower's property, (ii)
interest accrued and payable upon the RLC, (iii) any indebtedness, charges and
expenses that are the obligation of Borrower under this Senior Credit Agreement,
and (iv) any charges or matters necessary to cure any Event of Default.

         2.9 Assignment. Borrower shall have no right to any RLC Advance other
than to have the same disbursed by the Administrative Agent in accordance with
the disbursement provisions contained in this Senior Credit Agreement. Any
assignment or transfer, voluntary or involuntary, of this Senior Credit
Agreement or any right hereunder shall not be binding upon or in any way affect
the Banks without their written consent; the Administrative Agent, at the
direction of the Banks may make RLC Advances under the disbursement provisions
herein, notwithstanding any such assignment or transfer.

         2.10 Issuance of Letters of Credit.

         Agreement, (i) the Issuing Bank agrees from time to time before the RLC
         Maturity Date to issue Letters of Credit for the account of the
         Borrower either to credit enhance Bonds or for normal business
         purposes; and (ii) the Banks severally agree to participate in Letters
         of Credit issued for the account of the Borrower, subject to the prior
         approval by each Bank of the provisions of each Letter of Credit. Each
         reference in this Senior Credit Agreement to the "issue" or "issuance"
         or other forms of such words in relation to Letters of Credit shall be
         deemed to include any extension or renewal of a Letter of Credit.

                  (b) Each Letter of Credit shall (i) by its terms be issued in
         a Stated Amount; (ii) have a Stated Expiry Date no later than the RLC
         Maturity Date; (iii) expire or be terminated by the beneficiary
         thereunder on or before its Stated Expiry Date; (iv) not cause the RLC
         Balance after the issuance of said Letter of Credit to exceed the RLC
         Commitment; and (v) not cause the Outstanding LC Balance after the
         issuance of said Letter of Credit to exceed the Maximum LC Commitment.

                  (c) In addition to the conditions otherwise specified in this
         Section, the obligation of the Issuing Bank to issue a Letter of Credit
         shall be subject to the further condition precedent that the following
         statements shall be correct, and each of the application for such
         Letter of Credit and the issuance of such Letter of Credit shall
         constitute a representation and warranty by Borrower that on the date
         of the issuance of such Letter of Credit such statements are correct:

                           (i) The representations and warranties in Article 6
                  are correct on and as of the date of the issuance of such
                  Letter of Credit, before and after giving effect to such
                  issuance, as though made on and as of such date;

                           (ii) No Event of Default has occurred and is
                  continuing; and

                           (iii) The conditions in Section 2.2(a) are satisfied
                  as of the date of issuance of the Letter of Credit, before and
                  after giving effect to such issuance.

                  (d) In addition to the conditions otherwise specified in this
         Section, the obligations of the Issuing Bank to issue a Letter of
         Credit that is a Bond Letter of Credit shall be subject to the
         satisfaction of the following conditions precedent as determined by
         Lender in its reasonable discretion:


                                      -23-
<PAGE>   30

                           (i) The terms and provisions of the related Bond
                  Documents shall be reasonably acceptable to the Banks, which
                  shall provide among other things that all disbursements of
                  proceeds of the related Bonds shall be subject to the Banks'
                  written consent.

                           (ii) Borrower shall have delivered to the Banks an
                  executed Pledged Bond Agreement with respect to the related
                  Bonds.

                           (iii) The Banks shall have received executed copies
                  of the Bond Documents together with copies of written opinions
                  of counsel as to the tax exemption of the related Bonds and
                  reliance letters addressed to the Banks, allowing the Banks to
                  rely on such opinions.

                           (iv) Borrower shall have delivered to the Banks such
                  documents, executed by Borrower, as the Banks may reasonably
                  require, granting the Banks a security interest in all
                  property, personal or real, financed with the proceeds of said
                  Bonds, as well as in any accounts established with respect
                  thereto, together with financing statements, an environmental
                  indemnity agreement, contract assignments, a lender's ALTA
                  extended coverage title insurance policy as to the Banks'
                  security interest in any real property, and a project budget.

         2.11 Issuance Procedure for Letters of Credit. By delivery to the
Issuing Bank of an Issuance Request on or before 9:00 a.m. (Phoenix, Arizona
time) three (3) Business Days prior to the requested Issuance Date, and the
execution of such applications and agreements as the Issuing Bank may reasonably
request, Borrower may request the issuance of a Letter of Credit in such form as
Borrower may reasonably request. Each Issuance Request shall include the form of
the Letter of Credit, the amount and other terms thereof. Subject to the terms
and conditions of this Senior Credit Agreement, the Issuing Bank will issue such
Letter of Credit on the Issuance Date specified in the Issuance Request
submitted in connection therewith. The Issuing Bank and Borrower agree that all
Letters of Credit issued pursuant to the terms of this Article shall be subject
to the terms and conditions and entitled to the benefits of this Senior Credit
Agreement and the other Credit Documents.

         2.12 Letter of Credit Fees. Borrower agrees to pay to the
Administrative Agent, for distribution to the Banks pursuant to Section 9A.8
hereof, a non-refundable Letter of Credit fee (the "Letter of Credit Fee") equal
to the LIBOR Based Rate Factor then in effect per annum on the Stated Amount of
each Letter of Credit, computed on a daily basis, from and including the
Issuance Date of such Letter of Credit to the Stated Expiry Date ("Outstanding
Period"). The Letter of Credit Fee shall be payable in advance upon the issuance
of a Letter of Credit, except as to a Bond Letter of Credit for which it shall
be payable quarterly in arrears until such Bond


                                      -24-
<PAGE>   31

Letter of Credit's Stated Expiry Date. Upon an Event of Default, the Letter of
Credit Fee shall be equal to three hundred basis points (3.0%) above the LIBOR
Based Rate Factor. Borrower further agrees to pay to the Issuing Bank a charge
for all reasonable administrative expenses of the Issuing Bank in connection
with the issuance, amendment or modification (if any) and administration of the
Letter of Credit upon demand from time to time, which charge shall not exceed
$150.00 per draw, transfer or transaction.

         2.13 Disbursements. The Issuing Bank will notify Borrower of the
presentment for payment of a Letter of Credit by any beneficiary thereto,
together with notice of the date (the "Disbursement Date") such payment shall be
made. Subject to the terms and provisions of the Letter of Credit, the Issuing
Bank shall make such payment (a "Disbursement") to the beneficiary of the Letter
of Credit. Each such Disbursement shall be deemed to be an RLC Advance
hereunder.

         2.14 Reimbursement Obligations of Borrower. Borrower's obligation under
Section 2.13 to reimburse the Banks with respect to each Disbursement (including
interest thereon) in respect of any Letter of Credit shall be absolute and
unconditional under any and all circumstances and irrespective of any setoff,
counterclaim, or defense to payment which Borrower may have or have had against
the Banks, the Issuing Bank, the Administrative Agent or the beneficiary
thereof, including any defense based upon the occurrence of any Event of
Default, any draft, demand or certificate or other document presented under the
Letter of Credit proving to be forged, fraudulent, invalid or insufficient, the
failure of any Disbursement to conform to the terms of the Letter of Credit (if,
in Issuing Bank's good faith opinion, such Disbursement is determined to be
appropriate) or any non-application or misapplication by the beneficiary of the
proceeds of such Disbursement, or the legality, validity, form, regularity or
enforceability of the Letter of Credit; provided, however, that nothing herein
shall adversely affect the right of Borrower to commence any proceeding against
Issuing Bank for any wrongful Disbursement made by Issuing Bank under the Letter
of Credit as a result of acts or omissions constituting gross negligence or
wilful misconduct on the part of Issuing Bank.

         2.15 Nature of Reimbursement Obligations. Borrower shall assume all
risks of the acts, omissions or misuse of any Letter of Credit by the
beneficiary thereof. Neither the Banks nor the Issuing Bank (except to the
extent of its own gross negligence or wilful misconduct) shall be responsible
for:

                  (a) the form, validity, sufficiency, accuracy, genuineness or
         legal effect of any Letter of Credit or any document submitted by any
         party in connection with the issuance of any Letter of Credit, even if
         such document should in fact prove to be in any or all respects
         invalid, insufficient, inaccurate, fraudulent or forged;

                  (b) the form, validity, sufficiency, accuracy, genuineness or
         legal effect of any instrument transferring or assigning or purporting
         to transfer or assign any Letter of Credit;


                                      -25-
<PAGE>   32

                  (c) failure of any beneficiary of any Letter of Credit to
         comply fully with conditions required in order to demand payment under
         a Letter of Credit;

                  (d) errors, omissions, interruption or delays in transmission
         or delivery of any messages, by mail, cable, telegraph, telex or
         otherwise; or

                  (e) any loss or delay in the transmission or otherwise of any
         document or draft required by or from a beneficiary of a Letter of
         Credit in order to make a Disbursement under a Letter of Credit or of
         the proceeds thereof.

None of the foregoing shall affect, impair or prevent the vesting of any of the
rights or powers granted the Banks or the Issuing Bank hereunder. In furtherance
and extension, and not in limitation or derogation of any of the foregoing, any
action taken or omitted to be taken by the Banks or the Issuing Bank in good
faith shall be binding upon the Borrower and shall not put the Banks or the
Issuing Bank under any resulting liability to Borrower.

         2.16 Banks Obligation. Nothing herein shall be deemed to relieve any
Bank from its obligations to fulfill its Pro Rata Share of the RLC Commitment
hereunder or to prejudice any right which the Administrative Agent or the
Borrower may have against any Bank as a result of any default by such Bank
hereunder.

         2.17 Certain Requirements. The Issuing Bank is under no obligation to
Issue any Letter of Credit if:

                           (i) any order, judgment or decree of any Governmental
         Authority or arbitrator shall by its terms purport to enjoin or
         restrain the Issuing Bank from Issuing such Letter of Credit, or any
         requirement of law applicable to the Issuing Bank or any request or
         directive (with which it is customary for banks in the relevant
         jurisdiction to comply whether or not having the force of law) from any
         Governmental Authority with jurisdiction over the Issuing Bank shall
         prohibit, or request that the Issuing Bank refrain from, the Issuance
         of letters of credit generally or such Letter of Credit in particular
         or shall impose upon the Issuing Bank with respect to such Letter of
         Credit any restriction, reserve, or capital requirement (for which the
         Issuing Bank is not otherwise compensated hereunder) not in effect on
         the Closing Date, or shall impose upon the Issuing Bank any
         unreimbursed loss, cost, or expense which was not applicable on the
         Closing Date and which the Issuing Bank in good faith deems material to
         it;

                           (ii) the Issuing Bank has received written notice
         from any Bank, the Administrative Agent or Borrower, on or prior to the
         Business Day prior to the requested date of Issuance of such Letter of
         Credit, that one or more of the applicable conditions contained in
         Article 5 is not then satisfied;


                                      -26-
<PAGE>   33

                           (iii) the Stated Expiry Date of any requested Letter
         of Credit is not in accord with the requirements of Section 2.10(b),
         unless all of the Banks have approved such Stated Expiry Date;

                           (iv) any requested Letter of Credit does not provide
         for drafts, or is not otherwise in form and substance acceptable to the
         Issuing Bank, or the Issuance of a Letter of Credit shall violate any
         applicable policies of the Issuing Bank; or

                           (v) such Letter of Credit is to be used for a purpose
         other than as provided herein or denominated in a currency other than
         Dollars.

         2.18 Risk Participations, Drawings, and Reimbursements.

                  (a) Immediately upon the Issuance of each Letter of Credit,
each Bank shall be deemed to, and hereby irrevocably and unconditionally agrees
to, purchase from the Issuing Bank a participation in such Letter of Credit and
each drawing thereunder in an amount equal to the product of (i) the Pro Rata
Share of such Bank, times (ii) the maximum amount available to be drawn under
such Letter of Credit and the amount of any drawing, respectively. For purposes
of the applicable Commitment, each Issuance of a Letter of Credit shall be
deemed to utilize each Bank's Pro Rata Share of said Commitment by an amount
equal to the amount of such participation.

                  (b) In the event of any request for a drawing under a Letter
of Credit by the beneficiary or transferee thereof, the Issuing Bank will
promptly notify the Borrower. The Issuing Bank shall honor any Disbursement
request under any Letter of Credit only if (i) such request is delivered to the
Issuing Bank by the beneficiary of such Letter of Credit, and (ii) such request
is accompanied by the original documents required by the Letter of Credit for
any Disbursement. Except as otherwise provided herein, the Borrower shall
reimburse the Issuing Bank prior to 11:00 a.m. (Phoenix, Arizona local time) on
each date that any amount is paid by the Issuing Bank under any Letter of Credit
(each such date, an "Honor Date"), in an amount equal to the amount so paid by
the Issuing Bank. In the event the Borrower is required but fails to reimburse
the Issuing Bank for the full amount of any drawing under any Letter of Credit
by 11:00 a.m. (Phoenix, Arizona local time) on the Honor Date, the Issuing Bank
will promptly notify the Administrative Agent and the Administrative Agent will
promptly notify each Bank thereof. Any notice given by the Issuing Bank or the
Administrative Agent pursuant to this Section may be oral if immediately
confirmed in writing (including by facsimile); provided that the lack of such an
immediate confirmation shall not affect the conclusiveness or binding effect of
such notice.

                  (c) Each Bank shall upon any notice pursuant to this Section
make available to the Administrative Agent for the account of the Issuing Bank
an amount in Dollars and in immediately available funds equal to its Pro Rata
Share of the amount of the drawing, whereupon the Banks shall (subject to
paragraph (d)) each be deemed to have made a Variable Rate RLC Advance to the
Borrower in that amount. If any Bank so notified fails to make available to the


                                      -27-
<PAGE>   34

Administrative Agent for the account of the Issuing Bank the amount of such
Bank's Pro Rata Share of the amount of the drawing by no later than 3:00 p.m.
(Phoenix, Arizona local time) on the Honor Date, then interest shall accrue on
such Bank's obligation to make such payment, from the Honor Date to the date
such Bank makes such payment, at a rate per annum equal to the Federal Funds
Rate in effect from time to time during such period and such amount and interest
shall be immediately due and payable to the Administrative Agent; the obligation
of such Bank to make such payment to the Administrative Agent shall not be
waived by the Administrative Agent without the prior written consent of the
Borrower. The Administrative Agent will promptly give notice of the occurrence
of the Honor Date, but failure of the Administrative Agent to give any such
notice on the Honor Date or in sufficient time to enable any Bank to effect such
payment on such date shall not relieve such Bank from its obligations under this
Section.

                  (d) With respect to any unreimbursed drawing, the Borrower
shall be deemed to have incurred from the Issuing Bank a Variable Rate RLC
Advance in the amount of such drawing.

                  (e) Each Bank's obligation in accordance with this Senior
Credit Agreement to make the Variable Rate Advance, as contemplated by this
Section, as a result of a drawing under a Letter of Credit, shall be absolute
and unconditional and without recourse to the Issuing Bank and shall not be
affected by any circumstance, including (i) any set-off, counterclaim,
recoupment, defense, or other right which such Bank may have against the Issuing
Bank, the Borrower, or any other Person for any reason whatsoever, (ii) the
occurrence or continuance of a default, an Event of Default, or a Material
Adverse Effect, or (iii) any other circumstance, happening, or event whatsoever,
whether or not similar to any of the foregoing.

         2.19 Repayment of Participations.

                  (a) Upon (and only upon) receipt by the Administrative Agent
for the account of the Issuing Bank of immediately available funds from the
Borrower (i) in reimbursement of any payment made by the Issuing Bank under a
Letter of Credit with respect to which any Bank has paid the Administrative
Agent for the account of the Issuing Bank for such Bank's participation in such
Letter of Credit pursuant to Section 2.18, or (ii) in payment of interest
thereon, the Administrative Agent will pay to each Bank, in the same funds as
those received by the Administrative Agent for the account of the Issuing Bank,
the amount of such Bank's Pro Rata Share of such funds, and the Issuing Bank
shall receive the amount of the Pro Rata Share of such funds of any Bank that
did not so pay the Administrative Agent for the account of the Issuing Bank.

                  (b) If the Administrative Agent or the Issuing Bank is
required at any time to return to the Borrower, or to a trustee, receiver,
liquidator, custodian, or any official in any Insolvency Proceeding, any portion
of the payments made by the Borrower to the Administrative Agent for the account
of the Issuing Bank pursuant to paragraph (a) in reimbursement of a payment made
under a Letter of Credit or interest or fee thereon, each Bank shall, on demand
of the Administrative Agent, forthwith return to the Administrative Agent or the
Issuing Bank the


                                      -28-

<PAGE>   35



amount of its Pro Rata Share of any amounts so returned by the Administrative
Agent or the Issuing Bank plus interest thereon from the date such demand is
made to the date such amounts are returned by such Bank to the Administrative
Agent or the Issuing Bank, at a rate per annum equal to the Federal Funds Rate
in effect from time to time.

         2.20 Role of the Issuing Bank.

                  (a) Each Bank and Borrower agree that, in paying any drawing
under a Letter of Credit, the Issuing Bank shall not have any responsibility to
obtain any document (other than any sight draft and certificates expressly
required by the Letter of Credit) or to ascertain or inquire as to the validity
or accuracy of any such document or the authority of the Person executing or
delivering any such document.

                  (b) No Administrative Agent-related Person nor any of the
respective correspondents, participants or assignees of the Issuing Bank shall
be liable to any Bank for: (i) any action taken or omitted in connection
herewith at the request or with the approval of the Banks or (ii) any action
taken or omitted in the absence of gross negligence or willful misconduct.

                                 THE TERM A LOAN

         2A.1 Term A Loan Commitment.

                  (a) Subject to the conditions set forth herein, each Bank,
from time to time, shall fund, severally but not jointly, its Pro Rata Share of
such Term A Loan Advances as Borrower may request, provided that (a) the Term A
Loan Balance at any one time outstanding shall not exceed the Term A Loan
Commitment, and (b) the aggregate amount of a Bank's funding of the Term A Loan
Balance at any one time outstanding shall not exceed its Pro Rata Share of the
Term A Loan Commitment. The loan of each Bank shall be a single-advance term
loan, against which a Bank shall fund its Pro Rata Share of each Term A Loan
Advance to be made to Borrower provided that (i) there is no Event of Default
under any provision of this Senior Credit Agreement, (ii) no Term A Loan Advance
shall be made that would cause the Term A Loan Balance to exceed the Term A Loan
Commitment, and (iii) no Bank shall be obligated under any circumstances to fund
a Term A Loan Advance in excess of that Bank's Pro Rata Share of the requested
Term A Loan Advance. The Banks shall not be obligated to fund their Pro Rata
Share of any Term A Loan Advance if, after giving effect thereto, any of the
foregoing limitations would be exceeded.

                  (b) The failure of any Bank to fund its Pro Rata Share of a
Term A Loan Advance in accordance with its Pro Rata Share of the Term A Loan
Commitment shall not relieve any other Bank of its several obligations
hereunder, but no Bank shall be liable with respect to the obligation of any
other Bank hereunder.

         2A.2 Term A Notes. The Term A Loan of each Bank shall be evidenced by a
Term A Note, and shall bear interest and be payable to the order of each Bank
upon the terms and conditions contained therein. The aggregate amount funded by
a Bank under its Term A Loan Note shall be the principal amount owing and unpaid
on its Term A Note and its Term A Loan. The principal amount funded by a Bank
and all principal payments and prepayments thereof may be noted by such Bank on
a schedule attached to its Term A Note and shall be entered by the Bank on its
ledgers and computer records; provided that the failure of the Bank to make such
notations or entries shall not affect the principal amount owing and unpaid on
its Term A Note. The entries made in the ordinary course of business by a Bank
on its ledgers and computer records and any notations made in the ordinary
course of business by a Bank on any such schedule annexed to its Term A Note
shall be presumed to be accurate until the contrary is established. If
requested, Borrower shall confirm in writing to the Administrative Agent each
Term A Loan Advance.

         2A.3 Term A Loan. The Term A Loan shall bear interest and be payable to
the Banks upon the terms and conditions contained therein, which include the
following provisions:


                                      -30-
<PAGE>   37

                  (a) Interest shall accrue:

                           (i) Except to the extent that a portion of the Term A
                  Loan bears interest at the LIBOR Based Rate, on the unpaid
                  principal of the Term A Loan at the Variable Rate.

                           (ii) To the extent Borrower shall elect and to the
                  extent not otherwise provided herein, on the unpaid principal
                  of the Term A Loan at the LIBOR Based Rate.

                  (b) Principal shall be due and payable on the Payment Date in
         consecutive monthly installments equal to the Principal Payment,
         together with interest until the Term A Maturity Date.

                  (c) All interest shall be computed on the basis of a 360-day
         year and accrue on a daily basis for the actual number of days elapsed.
         No Interest Period shall begin on any day other than a Payment Date.

                  (d) The entire unpaid principal balance, all accrued and
         unpaid interest, and all other amounts payable under the Term A Note
         shall be due and payable in full on the Term A Maturity Date.

                  (e) The proceeds of the Term A Loan shall be disbursed in a
         single Term A Loan Advance.

                  (f) Borrower may, upon written notice to and received by the
         Administrative Agent not later than 9:00 a.m. (Phoenix, Arizona local
         time) (i) on the second Business Day, in the case of any conversion of
         a Variable Rate Term Portion into a LIBOR Based Rate Term Portion and
         (ii) on the first Business Day in the case of any conversion of a LIBOR
         Based Rate Term Portion into a Variable Rate Term Portion, prior to the
         date of the proposed conversion, convert any Term Portion of one type
         into a Term Portion of the other type, provided, however, that any
         conversion of a LIBOR Based Rate Term Portion (A) shall only be made on
         the last day of the applicable Interest Period except as otherwise
         provided herein, and (B) shall be made only as to a Term Portion in a
         minimum amount of $1,000,000.00 with integral multiples of $500,000.00
         in excess thereof. Each such notice of a conversion shall specify the
         date of such conversion and the Term Portion(s) to be converted. After
         receiving any such notice, the Administrative Agent shall promptly
         notify each Bank by telephone, telefacsimile or cable and deliver a
         copy thereof to each Bank.

                  (g) Each request for a Term A Loan Advance as well as each
         election by the Borrower that a Term A Loan Advance continue to bear
         interest at the LIBOR Based Rate after the end of an existing Interest
         Period and each conversion


                                      -31-
<PAGE>   38

         request shall be irrevocable and binding on Borrower once the request
         is received by the Agent and the Agent notifies the Banks of the
         request. Prior to the Agent's notice of the request to the Banks,
         Borrower may revoke the request. Borrower shall indemnify each Bank
         against any cost, loss or expense incurred by any Bank as a result of
         Borrower's failure to fulfill, on or before the date specified for a
         Term A Loan Advance in any request for a Term A Loan Advance, the
         conditions to such Term A Loan Advance set forth herein, including any
         cost, loss or expense incurred by reason of the liquidation or
         reemployment of deposits or other funds acquired by a Bank to fund such
         Term A Loan Advance when such Term A Loan Advance, as a result of such
         failure, is not made on the date so specified.

                  (h) No Term A Loan Advance shall be requested by Borrower to
         bear a LIBOR Based Rate, whether pursuant to a request for a Term A
         Loan Advance or a conversion hereunder, so long as there shall have
         occurred an Event of Default and such Event of Default is continuing.

                  (i) Nothing herein shall be deemed to relieve any Bank from
         its obligations to fulfill its Pro Rata Share of the Term A Loan
         Commitment hereunder or to prejudice any right which the Agent or the
         Borrower may have against any Bank as a result of any default by such
         Bank hereunder.

                  (j) Upon default, including failure to pay upon final
         maturity, the Banks, at their option, may also, if permitted under
         applicable law, do one or both of the following: (a) increase the
         applicable interest rate to the Default Rate, and/or (b) add any unpaid
         accrued interest to principal and such sum will bear interest therefrom
         until paid at the rate provided herein (including any increased rate).
         The interest rate will not exceed the maximum rate permitted by
         applicable law.

         2A.4 Notice of Term A Loan Advances. Term A Loan Advances shall be made
by the Banks to Borrower upon oral, telephonic or written notice from an
Authorized Officer to the Administrative Agent specifying the date and amount of
the requested Term A Loan Advance, provided that such oral or telephonic notice
shall be forthwith confirmed by an Authorized Officer in writing. Term A Loan
Advances may only be made to repay existing term Indebtedness of Borrower or for
such other purposes as the Banks shall permit in their sole and absolute
discretion. Notwithstanding anything herein to the contrary, the proceeds of the
Term A Loan shall be disbursed in a single Term A Loan Advance at the closing of
the Loans.

         2A.5 Conditions. The Banks shall have no obligation to make a Term A
Loan Advance unless and until all of the conditions and requirements of this
Senior Credit Agreement are fully satisfied. However, the Banks in their sole
and absolute discretion may elect to make a Term A Loan Advance prior to full
satisfaction of one or more such conditions and/or requirements. Notwithstanding
that a Term A Loan Advance is made, such unsatisfied conditions and/or


                                      -32-
<PAGE>   39

requirements shall not be waived or released thereby. Borrower shall be and
continue to be obligated to fully satisfy such conditions and requirements.

         2A.6 Assignment. Borrower shall have no right to a Term A Loan Advance
other than to have the same made by the Banks in accordance with the provisions
contained in this Senior Credit Agreement. Any assignment or transfer, voluntary
or involuntary, of this Senior Credit Agreement or any right hereunder shall not
be binding upon or in any way affect the Banks without their written consent;
the Banks may make a Term A Loan Advance under the provisions herein,
notwithstanding any such assignment or transfer.

                                 THE TERM B LOAN

         2B.1 Term B Loan Commitment.

                  (a) Subject to the conditions set forth herein, each Bank,
from time to time, shall fund, severally but not jointly, its Pro Rata Share of
such Term B Loan Advances as Borrower may request, provided that (a) the Term B
Loan Balance at any one time outstanding shall not exceed the Term B Loan
Commitment, and (b) the aggregate amount of a Bank's funding of the Term B Loan
Balance at any one time outstanding shall not exceed its Pro Rata Share of the
Term B Loan Commitment. The loan of each Bank shall be a multiple-advance line
of credit, against which a Bank shall fund its Pro Rata Share of each Term B
Loan Advance to be made to Borrower provided that (i) there is no Event of
Default under any provision of this Senior Credit Agreement, (ii) no Term B Loan
Advance shall be made that would cause the Term B Loan Balance to exceed the
Term B Loan Commitment, and (iii) no Bank shall be obligated under any
circumstances to fund a Term B Loan Advance in excess of that Bank's Pro Rata
Share of the requested Term B Loan Advance. The Banks shall not be obligated to
fund their Pro Rata Share of any Term B Loan Advance if, after giving effect
thereto, any of the foregoing limitations would be exceeded.

                  (b) The failure of any Bank to fund its Pro Rata Share of a
Term B Loan Advance in accordance with its Pro Rata Share of the Term B Loan
Commitment shall not relieve any other Bank of its several obligations
hereunder, but no Bank shall be liable with respect to the obligation of any
other Bank hereunder.

         2B.2 Term B Notes. The Term B Loan of each Bank shall be evidenced by a
Term B Note, and shall bear interest and be payable to the order of each Bank
upon the terms and conditions contained therein. The aggregate amount funded by
a Bank under its Term A Note shall be the principal amount owing and unpaid on
its Term B Note and its Term B Loan. The principal amount funded by a Bank and
all principal payments and prepayments thereof may be noted by such Bank on a
schedule attached to its Term B Note and shall be entered by the Bank on its
ledgers and computer records; provided that the failure of the Bank to make such
notations or entries shall not affect the principal amount owing and unpaid on
its Term B Note. The entries made in the ordinary course of business by a Bank
on its ledgers and computer records and any notations made in the ordinary
course of business by a Bank on any such schedule annexed to its Term B Note
shall be presumed to be accurate until the contrary is established. If
requested, Borrower shall confirm in writing to the Administrative Agent each
Term B Loan Advance.

         2B.3 Term B Loan. The Term B Loan shall be evidenced by the Term B
Note, and shall bear interest and be payable to the Banks upon the terms and
conditions contained therein, which include the following provisions:

                  (a)      Interest shall accrue:

                           (i) Except to the extent that a portion of the Term B
                  Loan bears interest at the LIBOR Based Rate, on the unpaid
                  principal of the Term B Loan at the Variable Rate.

                           (ii) To the extent Borrower shall elect and to the
                  extent not otherwise provided herein, on the unpaid principal
                  of the Term B Loan at the LIBOR Based Rate.

                  (b) Principal shall be due and payable on the Payment Date in
         consecutive monthly installments equal to the Principal Payment,
         together with interest until the Term B Maturity Date.

                  (c) All interest shall be computed on the basis of a 360-day
         year and accrue on a daily basis for the actual number of days elapsed.
         No Interest Period shall begin on any day other than a Payment Date.

                  (d) The entire unpaid principal balance, all accrued and
         unpaid interest, and all other amounts payable under the Term B Note
         shall be due and payable in full on the Term B Maturity Date.

                  (e) Each request for a Term B Loan Advance shall, in addition
         to complying with the other requirements in this Senior Credit
         Agreement, (i) specify the date and amount of the requested Term B Loan
         Advance, (ii) specify whether the Term B Loan Advance shall be a Term B
         Loan Advance that bears interest at the Variable Rate or shall be a
         Term B Loan Advance that bears interest at the LIBOR Based Rate, and
         (iii), if the Term B Loan Advance is to bear interest at the LIBOR
         Based Rate, (A) specify the Interest Period, (B) be delivered to
         Administrative Agent before 9:00 a.m. (Phoenix, Arizona local time) at
         least two (2) Business Days prior to the date of the requested Term B
         Loan Advance, and (C) be in a minimum amount of $1,000,000.00 with
         integral multiples of $500,000.00 in excess thereof. Any Term B Loan
         Advance not complying with the foregoing requirements for a Term B Loan
         Advance bearing interest at the LIBOR Based Rate shall bear interest at
         the Variable Rate.

                  (f) After receiving a request for a Term B Loan Advance in the
         manner provided herein, the Administrative Agent shall promptly, before
         11:30 a.m. (Phoenix, Arizona local time) on the date a Term B Loan
         Advance is requested, notify each Bank by telephone (confirmed promptly
         in writing), telefacsimile or cable of the terms of such request and
         such Bank's Pro Rata Share of the requested Term B Loan Advance. Each
         Bank shall, before 1:00 p.m. (Phoenix, Arizona local time) on the date
         a Term B Loan Advance is to be made as specified in a request for a
         Term B Loan Advance, deposit with the Administrative Agent such




                                      -35-

<PAGE>   42



         Bank's Pro Rata Share of the requested Term B Loan Advance in
         immediately available funds. Upon fulfillment of all applicable
         conditions set forth herein and after receipt by the Administrative
         Agent of such funds, the Administrative Agent shall pay or deliver all
         funds so received to the order of Borrower at the principal office of
         the Administrative Agent. The failure of any Bank to fund its Pro Rata
         Share of any Term B Loan Advance required of it hereunder shall not
         relieve any other Bank of its obligation to fund its Pro Rata Share of
         any Term B Loan Advance hereunder. If any Bank fails to fund its Pro
         Rata Share of the requested Term B Loan Advance and if all conditions
         to such Term B Loan Advance have apparently been satisfied, the
         Administrative Agent will make available to Borrower the funds received
         by it from the other Bank. Neither the Administrative Agent nor any
         Bank shall be responsible for the performance by any other Bank of its
         obligations hereunder.

                  Unless the Administrative Agent shall have received notice
         from a Bank prior to the date of any Term B Loan Advance that such Bank
         will not make available to the Administrative Agent such Bank's Pro
         Rata Share of the requested Term B Loan Advance, the Administrative
         Agent may assume that such Bank has made such amount available to the
         Administrative Agent on the date of such Term B Loan Advance in
         accordance with this Section and the Administrative Agent may, in
         reliance upon such assumption, make available a corresponding amount to
         or on behalf of Borrower on such date. If and to the extent any Bank
         shall not have so made its Pro Rata Share of the requested Term B Loan
         Advance available to the Administrative Agent (the "Term Principal
         Shortfall Amount"), Borrower agrees to repay the Term Principal
         Shortfall Amount to the Administrative Agent forthwith on demand,
         together with interest thereon for each day from (and including) the
         date such amount is made available to or on behalf of Borrower to (but
         excluding) the date such amount is repaid to the Administrative Agent,
         at the rate per annum equal to the rate otherwise applicable to the
         Term B Loan Advance in question.

                  (g) If Borrower desires that a LIBOR Based Rate Term Portion
         continue to bear interest at a LIBOR Based Rate after the end of an
         existing Interest Period, Borrower shall deliver to the Administrative
         Agent a notice making such election and specifying the new Interest
         Period. If Borrower does not deliver such notice within such time, then
         after the existing Interest Period the LIBOR Based Rate Term Portion
         shall become a Variable Rate Term Portion and shall bear interest at
         the Variable Rate.

                  (h) Borrower may, upon written notice to and received by the
         Administrative Agent not later than 9:00 a.m. (Phoenix, Arizona local
         time) (i) on the second Business Day, in the case of any conversion of
         a Variable Rate Term Portion into a LIBOR Based Rate Term Portion and
         (ii) on the first Business Day in the case of any conversion of a LIBOR
         Based Rate Term Portion into a Variable




                                      -36-

<PAGE>   43



         Rate Term Portion, prior to the date of the proposed conversion,
         convert any Term Portion of one type into a Term Portion of the other
         type, provided, however, that any conversion of a LIBOR Based Rate Term
         Portion (A) shall only be made on the last day of the applicable
         Interest Period except as otherwise provided herein, and (B) shall be
         made only as to a Term Portion in a minimum amount of $1,000,000.00
         with integral multiples of $500,000.00 in excess thereof. Each such
         notice of a conversion shall specify the date of such conversion and
         the Term Portion(s) to be converted. After receiving any such notice,
         the Administrative Agent shall promptly notify each Bank by telephone,
         telefacsimile or cable and deliver a copy thereof to each Bank.

                  (i) Each request for a Term B Loan Advance as well as each
         election by the Borrower that a Term B Loan Advance continue to bear
         interest at the LIBOR Based Rate after the end of an existing Interest
         Period and each conversion request shall be irrevocable and binding on
         Borrower once the request is received by the Agent and the Agent
         notifies the Banks of the request. Prior to the Agent's notice of the
         request to the Banks, Borrower may revoke the request. Borrower shall
         indemnify each Bank against any cost, loss or expense incurred by any
         Bank as a result of Borrower's failure to fulfill, on or before the
         date specified for a Term B Loan Advance in any request for a Term B
         Loan Advance, the conditions to such Term B Loan Advance set forth
         herein, including any cost, loss or expense incurred by reason of the
         liquidation or reemployment of deposits or other funds acquired by a
         Bank to fund such Term B Loan Advance when such Term B Loan Advance, as
         a result of such failure, is not made on the date so specified.

                  (j) No Term B Loan Advance shall be requested by Borrower to
         bear a LIBOR Based Rate, whether pursuant to a request for a Term B
         Loan Advance or a conversion hereunder, so long as there shall have
         occurred an Event of Default and such Event of Default is continuing.

                  (k) Nothing herein shall be deemed to relieve any Bank from
         its obligations to fulfill its Pro Rata Share of the Term Loan
         Commitment hereunder or to prejudice any right which the Agent or the
         Borrower may have against any Bank as a result of any default by such
         Bank hereunder.

                  (l) Upon default, including failure to pay upon final
         maturity, the Banks at their option, may also, if permitted under
         applicable law, do one or both of the following: (a) increase the
         applicable interest rate to the Default Rate, and/or (b) add any unpaid
         accrued interest to principal and such sum will bear interest therefrom
         until paid at the rate provided herein (including any increased rate).
         The interest rate will not exceed the maximum rate permitted by
         applicable law.

         2B.4 Notice of Term B Loan Advances. Term B Loan Advances shall be made
by the Banks to Borrower upon oral, telephonic or written notice from an
Authorized Officer to the




                                      -37-

<PAGE>   44



Administrative Agent specifying the date and amount of the requested Term B Loan
Advance, provided that such oral or telephonic notice shall be forthwith
confirmed by an Authorized Officer in writing. Term B Loan Advances may only be
made to repay Existing Subordinated Debt of Borrower prior to the Term B Loan
Expiration Date. No Term B Loan Advance shall be made after the Term B Loan
Expiration Date.

         2B.5 Conditions. The Banks shall have no obligation to make a Term B
Loan Advance unless and until all of the conditions and requirements of this
Senior Credit Agreement are fully satisfied. However, the Banks in their sole
and absolute discretion may elect to make a Term B Loan Advance prior to full
satisfaction of one or more such conditions and/or requirements. Notwithstanding
that a Term B Loan Advance is made, such unsatisfied conditions and/or
requirements shall not be waived or released thereby. Borrower shall be and
continue to be obligated to fully satisfy such conditions and requirements.

         2B.6 Assignment. Borrower shall have no right to a Term B Loan Advance
other than to have the same made by the Banks in accordance with the provisions
contained in this Senior Credit Agreement. Any assignment or transfer, voluntary
or involuntary, of this Senior Credit Agreement or any right hereunder shall not
be binding upon or in any way affect the Banks without their written consent;
the Banks may make a Term B Loan Advance under the provisions herein,
notwithstanding any such assignment or transfer.

                                   ARTICLE 3.

                    PAYMENTS, FEES AND EURODOLLAR PROVISIONS

         3.1      Payments.

                  (a) All payments and prepayments by the Borrower of principal
         of and interest on the Notes and all fees, expenses and any other
         Obligation payable to the Administrative Agent or the Banks in
         connection with the Loans shall be nonrefundable and made in Dollars or
         immediately available funds to the Banks not later than 11:00 a.m.
         (Phoenix, Arizona local time) on the dates called for under this Senior
         Credit Agreement, at the main office of the Administrative Agent (or
         the Issuing Bank, if the payment is governed by Section 3.11(b) hereof)
         in Phoenix, Arizona. Funds received after such hour shall be deemed to
         have been received by the Administrative Agent (or the Issuing Bank, if
         applicable) on the next Business Day. Payment to the Administrative
         Agent as aforesaid shall be deemed payment to the Banks as well,
         regardless of whether the Administrative Agent makes the distributions
         contemplated by Section 9A.8(a) hereof.

                  (b) Unless otherwise required by applicable law, payments will
         be applied first to accrued, unpaid interest, then to principal, and
         any remaining amount to any unpaid collection costs, late charges and
         other charges; provided, however, upon delinquency or other default,
         the Banks reserve the right to apply payments among principal,
         interest, late charges, collection costs and other charges at its
         discretion.

                  (c) Interest shall be due and payable on each Loan on each
         Payment Date and on each applicable Maturity Date.

                  (d) Whenever any payment to be made hereunder shall be stated
         to be due on a day which is not 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 interest,
         commission or fee, as the case may be.

         3.2      Fees.

                  (a) RLC Non-Use Fee. Borrower agrees to pay the Administrative
         agent for distribution to the Banks pursuant to Section 9A.8 hereof a
         quarterly fee (the "RLC Non-Use Fee") in an annualized amount equal to
         one-half percent (0.5%) of the average daily undrawn balance of the RLC
         Commitment during the prior calendar quarterly period. For purposes of
         calculating the RLC Non-Use Fee, the Outstanding LC Balance on any date
         shall be deemed to have been drawn. The RLC Non-Use Fee shall initially
         accrue from the Closing Date and shall be due




                                      -39-

<PAGE>   46



         and payable in arrears within three (3) Business Days after written
         notice of such amount due by the Administrative Agent to Borrower and
         shall be non-refundable.

                  (b) Term B Loan Non-Use Fee. Borrower agrees to pay
         Administrative agent for distribution to the Banks pursuant to Section
         9A.8 hereof a quarterly fee (the "Term B Loan Non-Use Fee") in an
         annualized amount equal to one-half percent (0.5%) of the average daily
         undrawn balance of the Term B Loan Commitment during the prior calendar
         quarterly period. The Term B Loan Non-Use Fee shall accrue from the
         Closing Date until the Term B Loan Expiration Date and shall be due and
         payable in arrears within three (3) Business Days after written notice
         of such amount due by the Administrative Agent to Borrower and shall be
         non-refundable.

                  (c) Termination Fee. Borrower agrees to pay Administrative
         agent for distribution to the Banks pursuant to Section 9A.8 hereof a
         termination fee (the "Termination Fee") in an amount equal to one
         percent (1.0%) of the RLC Commitment and the aggregate outstanding
         balances of the Term Loans in the event that the Loans are cancelled or
         prepaid due to a sale or merger of Borrower's business.

                  (d)  Letter of Credit Fee.  See Section 2.12.

         3.3 Computations. All fees and interest on each Note shall be computed
on the basis of a year of 360-days/year and accrue on a daily basis for the
actual number of days elapsed.

         3.4 Maintenance of Accounts. The Banks shall maintain, in accordance
with their usual practice, an account or accounts evidencing the indebtedness of
the Borrower and the amounts payable and paid from time to time hereunder. In
any legal action or proceeding in respect of this Senior Credit Agreement, the
entries made in the ordinary course of business in such account or accounts
shall be presumptive, absent manifest error, evidence of the existence and
amounts of the obligations of the Borrower therein recorded. The failure to
record any such amount shall not, however, limit or otherwise affect the
obligations of the Borrower hereunder to repay all amounts owed hereunder,
together with all interest accrued thereon as provided in the Notes.

         3.5      Certain Contingencies.

                  (a) If the contingency contemplated by Section 3.6, 3.7(b) or
         3.7(c) should occur, the Borrower may at any time after receipt of such
         notice, and as long as the circumstances giving rise to the relevant
         claim continue, require the Banks to terminate upon not less than
         thirty days' notice the participation agreement with such participant,
         unless such participant has waived any claim to payment under those
         provisions.



                                      -40-

<PAGE>   47



                  (b) If circumstances arise which would (or would upon the
         giving of notice) entitle a Bank to receive additional payments
         pursuant to Section 3.6, 3.7(b) or 3.7(c), then the Bank shall
         promptly, upon becoming aware of such circumstances, notify the
         Borrower and, to the extent that it can legally do so without material
         prejudice to its own position, the Bank shall take such reasonable
         steps as may be available to it to mitigate the effects of such
         circumstances.

         3.6 Increased Capital Requirements. In the event that, as a result of
any Regulatory Change, compliance by any Bank with any applicable law or
governmental rule, requirement, regulation, guideline or order (with which it is
customary for banks in the relevant jurisdiction to comply whether or not having
the force of law) has or would have the effect of reducing the rate of return on
the capital of the Bank or any institution controlling the Bank as a consequence
of or with reference to any Commitment, the issuance of a Letter of Credit or
amounts outstanding under the Notes to a level below that which the Bank or such
other corporation could have achieved but for such change or compliance (taking
into consideration the policies of the Bank or such other corporation with
respect to capital), then from time to time the Borrower shall pay to such Bank
such additional amount or amounts as will compensate the Bank for such
reduction. The Bank will notify the Borrower of any Regulatory Change that will
entitle the Bank to compensation pursuant to this Section as promptly as
practicable, but in any event within ninety (90) days after the Bank obtains
knowledge thereof; provided, however, that if the Bank fails to give such notice
within ninety (90) days after it obtains knowledge of such a Regulatory Change,
the Bank shall, with respect to compensation payable in respect of any costs
resulting from such Regulatory Change, only be entitled to payment for costs
incurred from and after the date that the Bank does give such notice. Such Bank
shall deliver to the Borrower a written certificate which states the additional
amount(s) due and payable, showing in reasonable detail the calculation of such
amount and provide evidence to substantiate the Bank's claim for such amount(s).

         3.7      Special Provisions for LIBOR Based Rate Advances.

                  (a) Funding: Notwithstanding any provision of the Credit
         Documents to the contrary, the Banks shall be entitled to fund and
         maintain their funding of all or any part of any Advance in any manner
         they see fit, provided, however, that for the purposes of the Notes,
         all determinations thereunder shall be made as if the Banks had
         actually funded and maintained each Advance bearing interest at the
         LIBOR Based Rate during the Interest Period therefor through the
         purchase of deposits having a maturity corresponding to the last day of
         the Interest Period and bearing an interest rate equal to the LIBOR
         Based Rate for such Interest Period.

                  (b) Inadequacy of Eurodollar Pricing: If, due to any
         Regulatory Change, there shall be any increase in the cost to a Bank of
         agreeing to make or making, funding, or maintaining Advances bearing
         interest at the LIBOR Based Rate (including, without limitation, any
         increase in any applicable reserve requirement), then the Borrower
         shall from time to time, upon demand by the Bank, pay to the Bank such
         amounts as the Bank may reasonably determine to be necessary to




                                      -41-

<PAGE>   48



         compensate the Bank for any additional costs that the Bank reasonably
         determines are attributable to such Regulatory Change. The Bank will
         notify the Borrower of any Regulatory Change that will entitle the Bank
         to compensation pursuant to this paragraph as promptly as practicable,
         but in any event within ninety (90) days after the Bank obtains
         knowledge thereof; provided, however, that if the Bank fails to give
         such notice within ninety (90) days after it obtains knowledge of such
         a Regulatory Change, the Bank shall, with respect to compensation
         payable in respect of any costs resulting from such Regulatory Change,
         only be entitled to payment for costs incurred from and after the date
         that the Bank does give such notice. The Bank will furnish to the
         Borrower a certificate setting forth in reasonable detail the basis for
         the amount of each request by the Bank for compensation under this
         paragraph. Determinations by the Bank of the amounts required to
         compensate the Bank shall be conclusive, absent manifest error. The
         Bank shall be entitled to compensation in connection with any
         Regulatory Change only for costs actually incurred by the Bank.

                  (c) Illegality: Notwithstanding any provision of the Credit
         Documents, if a Bank shall notify the Borrower that as a result of a
         Regulatory Change it is unlawful for the Bank to make Advances at the
         LIBOR Based Rate, or to fund or maintain Advances bearing interest at
         the LIBOR Based Rate , (i) the obligations of the Bank to make Advances
         at the LIBOR Based Rate and to convert Advances to the LIBOR Based Rate
         shall be suspended until the Bank shall notify the Borrower that the
         circumstances causing such suspension no longer exist, and (ii) in the
         event such Regulatory Change makes the maintenance of Advances at the
         LIBOR Based Rate unlawful, the Borrower shall forthwith prepay in full
         all Advances bearing interest at the LIBOR Based Rate then outstanding,
         together with interest accrued thereon and all amounts in connection
         with such prepayment specified herein, unless the Borrower, within five
         (5) Business Days of notice from the Bank, converts all Advances
         bearing interest at the LIBOR Based Rate then outstanding into Advances
         bearing interest at the Variable Rate pursuant to the conversion
         procedures herein and pays all amounts in connection with such
         prepayments or conversions specified herein.

                  (d) Market Disruption: Notwithstanding any other provision of
         the Credit Documents, if prior to the commencement of any Interest
         Period, the Banks shall determine (i) that United States dollar
         deposits in the amount of any Advance bearing interest at the LIBOR
         Based Rate to be outstanding during such Interest Period are not
         readily available to the Banks in the London interbank market, or (ii)
         by reason of circumstances affecting the London interbank market,
         adequate and reasonable means do not exist for ascertaining the LIBOR
         Based Rate for such Interest Period in the manner prescribed in the
         definition of "LIBOR Based Rate," then the Administrative Agent shall
         promptly give notice thereof to the Borrower and the obligation of the
         Banks to create, continue, or effect by conversion any Advance bearing
         interest at the LIBOR Based Rate in such amount and for such




                                      -42-

<PAGE>   49



         Interest Period shall terminate until United States dollar deposits in
         such amount and for the Interest Period shall again be readily
         available in the London interbank market and adequate and reasonable
         means exist for ascertaining the LIBOR Based Rate.

                  (e) Prepayment: Borrower may, upon at least two (2) Business
         Days' notice in the case of LIBOR Based Rate Advances and one (1)
         Business Day's notice in the case of Variable Rate Advances to the
         Administrative Agent stating the proposed date and aggregate principal
         amount of the prepayment, and if such notice is given Borrower shall,
         prepay the outstanding principal balance of the Loan in whole or in
         part at any time prior to the applicable Maturity Date as stated in
         such notice by Borrower. With any prepayment of a LIBOR Based Rate
         Advance or with any conversion of a LIBOR Based Rate Advance to a
         Variable Rate Advance, in either case other than on the last Business
         Day of the Interest Period for such LIBOR Based Rate Advance (including
         any such prepayment made voluntarily or involuntarily as a result of
         the acceleration of maturity upon a default or otherwise), Borrower
         shall pay all accrued interest on the principal amount prepaid with
         such prepayment and, on demand, shall reimburse the Banks and hold the
         Banks harmless from all losses and expenses incurred by the Banks as a
         result of such prepayment, including, without limitation, any losses
         and expenses arising from the liquidation or reemployment of deposits
         acquired to fund or maintain the principal amount prepaid. Such
         reimbursement shall be calculated as though the Banks funded the
         principal amount prepaid through the purchase of U.S. 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
         Based Rate for such Interest Period, whether in fact that is the case
         or not. The Banks' determination of the amount of such reimbursement
         shall be conclusive in the absence of manifest error.

                         REPRESENTATIONS AND WARRANTIES

         To induce the Banks to make the Loans, Company and each Co-Borrower to
the extent applicable represents and warrants to the Banks that:

         6.1 Organization and Good Standing. It is duly organized under the laws
of the state of its organization, is validly existing and is in good standing,
to the extent required by law, in each state in which it is doing business. It
has the legal power and authority to own its properties and assets and to
transact the business in which it is engaged and is or will be qualified in
those states wherein the nature of its proposed business and property will make
such qualifications necessary or appropriate in the future.

         6.2 Authorization and Power. It has the corporate power and requisite
authority to execute, deliver and perform this Senior Credit Agreement, the
Notes and the other Credit Documents to be executed by it; it is duly authorized
to, and has taken all action, corporate or otherwise, necessary to authorize it
to, execute, deliver and perform this Senior Credit Agreement, the Notes and
such other Credit Documents and is and will continue to be duly authorized to
perform this Senior Credit Agreement, the Notes and such other Credit Documents.

         6.3 No Conflicts or Consents. Neither the execution and delivery of
this Senior Credit Agreement, the Notes or the other Credit Documents to which
it is a party, nor the consummation of any of the transactions herein or therein
contemplated, nor compliance with the terms and provisions hereof or with the
terms and provisions thereof, (a) will contravene or conflict with: (i) any
provision of law, statute or regulation to which it is subject, (ii) any
judgment, license, order or permit applicable to it, (iii) any indenture, loan
agreement, mortgage, deed of trust, or other agreement or instrument to which it
is a party or by which it may be bound, or to which it may be subject, or (b)
will violate any provision of its organizational documents. No consent,
approval, authorization or order of any court or Governmental Authority or other
Person is required in connection with the execution and delivery by it of the
Credit Documents or to consummate the transactions contemplated hereby or
thereby, or if required, such consent, approval, authorization or order shall
have been obtained.

         6.4 Enforceable Obligations. This Senior Credit Agreement, the Notes
and the other Credit Documents are the legal, valid and binding obligations of
Borrower, enforceable against Borrower in accordance with their respective
terms, except as limited by bankruptcy, insolvency or other laws or equitable
principles of general application relating to the enforcement of creditors'
rights.

         6.5 Financial Condition. Company has delivered to the Banks copies of
the Company's audited consolidated financial statements as most recently filed
with the SEC. Such financial statements, in all material respects, fairly
present the financial position of Borrower as of such date and have been
prepared in accordance with GAAP. Since the date thereof, Company has not




                                      -48-

<PAGE>   55



discovered any obligations, liabilities or indebtedness (including contingent
and indirect liabilities and obligations or unusual forward or long-term
commitments) which in the aggregate are material and adverse to the financial
position or business of Company that should have been but were not reflected in
such financial statements. No changes having a Material Adverse Effect have
occurred in the financial condition or business of Company since its most recent
filings with the SEC.

         6.6 Full Disclosure. There is no material fact that it has not
disclosed to the Banks that would have a Material Adverse Effect. No certificate
or statement delivered herewith or heretofore by it to the Banks in connection
with negotiations of this Senior Credit Agreement, contains any untrue statement
of a material fact or omits to state any material fact necessary to keep the
statements contained herein or therein from being misleading.

         6.7 No Default. No event or condition has occurred and is continuing
that constitutes an Event of Default.

         6.8 Significant Debt Agreements. It is not in default in any material
respect under any Significant Debt Agreement.

         6.9 No Litigation. There are no actions, suits or legal, equitable,
arbitration or administrative proceedings pending, or to its actual knowledge
overtly threatened, against Borrower that would, if adversely determined, have a
Material Adverse Effect.

         6.10 Taxes. It has filed or caused to be filed all returns and reports
which are required to be filed by any jurisdiction, and has paid or made
provision for the payment of all taxes, assessments, fees or other governmental
charges imposed upon its properties, income or franchises, as to which the
failure to file or pay would have a Material Adverse Effect, except such
assessments or taxes, if any, which are being contested in good faith by
appropriate proceedings.


         6.11 ERISA. (a) No Reportable Event has occurred and is continuing with
respect to any Plan; (b) PBGC has not instituted proceedings to terminate any
Plan; (c) neither the Borrower, any member of the Controlled Group, nor any
duly-appointed administrator of a Plan (i) has incurred any liability to PBGC
with respect to any Plan other than for premiums not yet due or payable or (ii)
has instituted or intends to institute proceedings to terminate any Plan under
Section 4041 or 4041A of ERISA; and (d) each Plan of Borrower has been
maintained and funded in all material respects in accordance with its terms and
in all material respects in accordance with all provisions of ERISA applicable
thereto. Neither the Borrower nor any of its Subsidiaries participates in, or is
required to make contributions to, any Multi-employer Plan (as that term is
defined in Section 3(37) of ERISA).

         6.12 Compliance with Law. It is in substantial compliance with all
laws, rules, regulations, orders and decrees that are applicable to it, or its
properties, noncompliance with which would have a Material Adverse Effect.

         6.13 Survival of Representations, Etc. All representations and
warranties by Borrower herein shall survive the making of the Loans and the
execution and delivery of the Notes; any investigation at any time made by or on
behalf of the Banks shall not diminish the Banks' right to rely on the
representations and warranties herein.

Senior Credit Agreement are true and correct.

         6.15     No Stock Purchase.

                  (a) No part of the proceeds of any financial accommodation
         made by the Banks in connection with this Senior Credit Agreement will
         be used to purchase or carry "margin stock," as that term is defined in
         Regulation U, or to extend credit to others for the purpose of
         purchasing or carrying such margin stock.

                  (b) No portion of any Advance or Loan made hereunder shall be
         used directly or indirectly to purchase ineligible securities, as
         defined by applicable regulations of the Federal Reserve Board,
         underwritten by any affiliate of Banc One Corporation during the
         underwriting period and for 30 days thereafter.

         6.16 Solvent. It (both before and after giving effect to the Loans
contemplated hereby) is solvent, has assets having a fair value in excess of the
amount required to pay its probable liabilities on its existing debts as they
become absolute and matured, and has, and will have, access to adequate capital
for the conduct of its business and the ability to pay its debts from time to
time incurred in connection therewith as such debts mature.

         6.17 Advances. Each request for an Advance or for the extension of any
financial accommodation by the Banks whatsoever shall constitute an affirmation
that the representations and warranties contained herein are, true and correct
as of the time of such request. All representations and warranties made herein
shall survive the execution of this Senior Credit Agreement, all advances of
proceeds of the Loans and the execution and delivery of all other documents and
instruments in connection with the Loans and/or this Senior Credit Agreement, so
long as any Bank has any commitment to lend hereunder and until the Loans have
been paid in full and all of Borrower's obligations under this Senior Credit
Agreement and the Notes been fully discharged.

on Schedule 6.18, Borrower has no existing direct or indirect Subsidiary that

         presently conducted and as contemplated to be conducted in the future
         are Year 2000 Compliant or will be Year 2000 Compliant within a period
         of time calculated to result in no material disruption of any of
         Borrower's business operations. For purposes of these provisions, "Year
         2000 Compliant" means that such Systems are designed to be used prior
         to, during and after the Gregorian calendar year 2000 A.D. and will
         operate during each such time period without error relating to date
         data, specifically including any error relating to, or the product of,
         date data which represents or references different centuries or more
         than one century.

                  (b) Borrower has: (1) undertaken a detailed inventory, review,
         and assessment of all areas within its business and operations that
         could be adversely affected by the failure of Borrower to be Year 2000
         Compliant on a timely basis; (2) developed a detailed plan and time
         line for becoming Year 2000 Compliant on a timely basis, and (3) to
         date, implemented that plan in accordance with that timetable in all
         material respects.

         6.20 Existing Subordinated Debt. The Obligation and the Loans are
senior in right of payment to the Existing Subordinated Debt.

         properties.

         period of sixty (60) days;

                  (k) Any of the following events shall occur with respect to
         any Multi-Employer Pension Plan (as that term is defined in Section
         4001(a)(3) of ERISA) to which Borrower contributes or contributed on
         behalf of its employees and the Banks determine in good faith that the
         aggregate liability likely to be incurred by Borrower, as a result of
         any of the events specified in Subsections (i), (ii) and (iii) below,
         will have an effect in excess of $250,000.00; (i) Borrower incurs a

                  (l) The occurrence of a Change in Control or a material change
         in the management of the Company without the written consent of the

         the financial condition of Borrower or a material change in the
         management of Borrower, in either case that results in a Material

         prospect of payment or performance of the Obligation is impaired.

         9.2 Remedies Upon Event of Default. If an Event of Default shall have
occurred and be continuing, then the Administrative Agent, at the request of the
Required Banks may, at their sole option, exercise any one or more of the
following rights and remedies, and any other remedies provided in any of the
Credit Documents, as the Required Banks in their sole discretion may deem
necessary or appropriate, all of which remedies shall be deemed cumulative, and
not alternative:

                  accommodations in any form to or for the benefit of Borrower

                                      -63-

<PAGE>   70



                  declare the principal of, and all interest then accrued on,
                  the Notes and any other liabilities hereunder to be forthwith
                  due and payable, whereupon the same shall become immediately
                  due and payable without presentment, demand, protest, notice
                  of default, notice of acceleration or of intention to
                  accelerate or other notice of any kind all of which Borrower
                  hereby expressly waives, anything contained herein or in the
                  Notes to the contrary notwithstanding;

                           (ii)  Reduce any claim to judgment;

                           (iii) Without notice of default or demand, pursue and
                  enforce any of the Banks' and the Administrative Agent's
                  rights and remedies under the Credit Documents, or otherwise
                  provided under or pursuant to any applicable law or agreement;

                           (iv)  Notify the respective Trustee of any Bonds for
                 which a Bond Letter of Credit is outstanding of such Event of
                 Default and direct such Trustee to take such action or actions
                 as permitted under the related Indenture; and/or

                           (v)   Require the Borrower to deposit with the
                 Administrative Agent cash in an amount equal to the Outstanding
                 LC Balance;

provided, however, that if any Event of Default specified in Sections 9.1(g) and
9.1(h) shall occur, the principal of, and all interest on, the Notes and other
liabilities hereunder shall thereupon become due and payable concurrently
therewith, without any further action by the Banks and without presentment,
demand, protest, notice of default, notice of acceleration or of intention to
accelerate or other notice of any kind, all of which Borrower hereby expressly
waives.

         Upon the occurrence and during the continuance of any Event of Default,
the Administrative Agent on behalf of the Banks, at the request of the Required
Banks is hereby authorized at any time and from time to time, without notice to
Borrower (any such notice being expressly waived by Borrower), to set off and
apply any and all moneys, securities or other property of Borrower and the
proceeds therefrom, now or hereafter held or received by or in transit to the
Banks or their agents, from or for the account of Borrower, whether for safe
keeping, custody, pledge, transmission, collection or otherwise, and also upon
any and all deposits (general or special) and credits of Borrower, and any and
all claims of Borrower against the Banks at any time existing. The Banks agree
to notify Borrower promptly after any such setoff and application, provided that
the failure to give such notice shall not affect the validity of such setoff and
application. The rights of the Banks under this Section are in addition to other
rights and remedies (including, without limitation, other rights of setoff)
which the Banks may have.





                                      -64-

<PAGE>   71



         Upon the occurrence and during the continuance of any Event of Default,
the Banks are also authorized to notify each Trustee of such Event of Default
and direct that each Trustee accelerate the maturity of all applicable Bonds
then outstanding and provide a copy of such notice to the Borrower and the
Issuer and/or request the Trustee to redeem the applicable Bonds in whole or in
part or to cause a mandatory tender thereof.

         9.3 Performance by the Banks. Should Borrower fail to perform any
covenant, duty or agreement with respect to the payment of taxes, obtaining
licenses or permits, or any other requirement contained herein or in any of the
Credit Documents within the period provided herein, if any, for correction of
such failure, the Banks may, at their option, perform or attempt to perform such
covenant, duty or agreement on behalf of Borrower. In such event, Borrower
shall, at the request of the Required Banks, promptly pay any amount expended by
the Banks and/or the Administrative Agent in such performance or attempted
performance to the Administrative Agent at its main office in Phoenix, Arizona,
together with interest thereon at the Default Rate, from the date of such
expenditure until paid. Notwithstanding the foregoing, it is expressly
understood that neither the Banks nor the Administrative Agent assume any
liability or responsibility for the performance of any duties of Borrower
hereunder or under any of the Credit Documents or other control over the
management and affairs of Borrower.

                                   ARTICLE 9A

                              ADMINISTRATIVE AGENT

         9A.1 Appointment and Authorization. Each Bank hereby irrevocably
appoints and authorizes the Administrative Agent to act on behalf of such Bank
to the extent provided herein or in any of the Credit Documents or any other
document or instrument delivered hereunder or in connection herewith, and to
take such other action as may be reasonably incidental thereto as determined by
Administrative Agent.

         9A.2 Exculpation. Administrative Agent shall be entitled to rely upon
advice of counsel concerning legal matters, and upon this Senior Credit
Agreement, any Credit Documents and any schedule, certificate, statement,
report, notice or other writing which it believes to be genuine or to have been
presented by a proper person. Neither Administrative Agent nor any of its
directors, officers, employees, or agents shall (a) be responsible for any
recitals, representations or warranties contained in, or for the execution,
validity, genuineness, effectiveness or enforceability of, this Senior Credit
Agreement, any Credit Documents or any other instrument or document delivered
hereunder or in connection herewith, (b) be under any duty to inquire into or
pass upon any of the foregoing matters, or to make any inquiry concerning the
performance by the Borrower or any other obligor of its obligations, or (c) in
any event, be liable as such for any action taken or omitted by it or them,
except for its or their own gross negligence or wilful misconduct. The agency
hereby created shall in no way impair or affect any of the rights and powers of,
or impose any duties or obligations upon, Administrative Agent in its individual
capacity.

         9A.3 Administrative Agent and Affiliates. Administrative Agent has the
same rights and powers hereunder and under the Credit Documents as any other
Bank and may exercise the same as though it were not the Administrative Agent.
Administrative Agent and its Affiliates may accept deposits from, lend money to,
and generally engage in any kind of banking, trust or other business with
Borrower and any Affiliate of Borrower, as if it were not the Administrative
Agent and without any duty to account therefor to the Banks. Administrative
Agent need not account to any other Bank for any monies received by it for
reimbursement of its costs and expenses as Administrative Agent hereunder, or
for any monies received by it in its capacity as a Bank hereunder, except as
otherwise provided herein.

         9A.4 Banks' Credit Decisions. Each Bank has made, and shall continue to
make, its own independent investigation or evaluation of the operations,
business, property and condition, financial and otherwise, of the Borrower, in
connection with the making of its respective Commitment, and each has made its
own appraisal of the creditworthiness of the Borrower. Except as explicitly
provided herein, the Administrative Agent has no duty or responsibility, either
initially or on a continuing basis, to provide any Bank with any credit or other
information with respect to such operations, business, property, condition or
creditworthiness, whether such information comes into its possession on or
before an Event of Default or at any time thereafter. Each Bank agrees and
acknowledges that Administrative Agent makes no representations or




                                      -66-

<PAGE>   73



warranties about the creditworthiness of the Borrower or with respect to the
legality, validity, sufficiency or enforceability of this Senior Credit
Agreement or any of the Credit Documents.

         9A.5 Indemnification. Each Bank agrees to indemnify, hold harmless and
defend the Administrative Agent (to the extent not reimbursed by the Borrower),
ratably according to its Pro Rata Share, from and against any and all
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements of any kind or nature whatsoever which may be
imposed on, incurred by or asserted against the Administrative Agent in any way
relating to or arising out of this Senior Credit Agreement or the Credit
Documents or any action taken or omitted by the Administrative Agent under the
Senior Credit Agreement or Credit Documents; provided, that no Bank shall be
liable for any portion of such liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements resulting
from the Administrative Agent's gross negligence or wilful misconduct. Without
limitation of the foregoing, each Bank agrees to reimburse the Administrative
Agent promptly upon demand for its Pro Rata Share of any out-of-pocket expenses
(including, without limitation, attorney's fees and expenses) incurred by the
Administrative Agent in connection with the preparation, execution, delivery,
administration, modification, amendment or enforcement (whether through
negotiations, legal proceedings or otherwise) of, or legal advice in respective
rights or responsibilities under, this Senior Credit Agreement and the Credit
Documents to the extent that the Administrative Agent is not reimbursed for such
expenses by the Borrower; provided, that no Bank shall be liable for any portion
of any such expenses resulting from the Administrative Agent's gross negligence
or wilful misconduct.

         9A.6     Administration.

                  (a) Administrative Agent shall administer and manage the Loans
in the ordinary course of its business and in accordance with its usual
practices and that degree of care it would use in administering, managing, and
servicing facilities of similar size and type for its own account. Each Bank
expressly agrees that, except as expressly otherwise provided herein,
Administrative Agent shall, in accordance with such practices and degree of
care, make any and all decisions and is hereby authorized to do or cause to be
done any and all acts regarding the administration of the facilities in
accordance with its sole and absolute discretion.

                  (b) Unless in each case consented to in writing by all the
Banks, the Administrative Agent shall not (i) agree to the modification or
waiver of any of the terms of any of the Credit Documents, or (ii) consent to
any act or omission by the Borrower, or (iii) exercise any rights which the
Administrative Agent may have with respect to the Loans, the Notes, or any of
the other Credit Documents, if any such agreement, consent or exercise would:

                           (i) change or modify the interest rate and repayment
                  provisions set forth in the Credit Documents;

                           (ii) increase the RLC Commitment;





                                      -67-

<PAGE>   74



                           (iii) extend the maturity date of the Loans;

                           (iv) postpone any date for payment or forgive the
                  payment of principal of, or interest on, the Loans or the
                  payment of any other sum due under the Credit Documents;

                           (v) change or modify or waive any Financial Covenant;

                           (vi) waive any Event of Default; or

                           (vii) allow any assignment by Borrower of any right
                  or interest in the Credit Documents.

                  (c) Other than upon the occurrence of an Event of Default
hereunder, any decision or consent required hereunder shall be made jointly by
the Banks and the Administrative Agent instructed accordingly. Upon the
occurrence of an Event of Default hereunder, the Banks shall consult with each
other and determine whether, and in what manner and to what extent, any and all
rights hereunder and under the Credit Documents shall be exercised. The course
of action so agreed upon shall set forth what matters, if any, shall require the
further consent of the Banks and shall be carried out by Administrative Agent in
its name on behalf of the Banks.

                  (d) As to any matters which are subject to the consent of all
of the Banks, the Administrative Agent shall not be permitted or required to
exercise any discretion or take any action except with such consent. The
Administrative Agent shall be fully protected by the Banks severally and in
accordance with their respective Pro Rata Share in so acting or in so refraining
from action, but in no event shall the Administrative Agent be required to take
any action which exposes the Administrative Agent to personal liability which is
contrary to this Senior Credit Agreement or the Credit Documents or applicable
law.

                  (e) All communications from the Administrative Agent to the
Banks requesting the Banks' determination, consent, approval or disapproval
shall be given in the form of a written notice to each Bank containing (i) a
reasonably detailed description of the matter or thing as to which such
determination, approval, consent or disapproval is requested, accompanied by
such information in Administrative Agent's possession which, in Administrative
Agent's opinion, is reasonably relevant to such determination, approval, consent
or disapproval, and (ii) the course of action and determination recommended by
the Administrative Agent in respect thereof. Each Bank shall reply within ten
(10) Business Days after such written notice is given by Administrative Agent,
and, if such reply is not so given by a Bank, such course of action shall be
deemed to have been approved by such Bank.

         9A.7 Default by a Bank. In the event that any Bank (the "Defaulting
Bank") fails to make timely payment to Administrative Agent of any sum due under
this Senior Credit Agreement, including without limitation, such Bank's Pro Rata
Share of any Advance, Disbursement or liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, 




                                      -68-

<PAGE>   75


costs and expenses or any other expenses or amounts due Administrative Agent,
the non-defaulting Bank may, but shall not be required to, advance such amount
and recover such amount on demand from the Defaulting Bank, together with
interest thereon at the Federal Funds Rate commencing on the date such amount
was made available to Administrative Agent and ending on the date Administrative
Agent recovers such amount. Until the full repayment is made to Administrative
Agent of such amount funded on behalf of the Defaulting Bank together with
interest thereon from the date advanced to the date repaid by the Defaulting
Bank at the Federal Funds Rate, the right of the Defaulting Bank to participate
in decisions or consents hereunder shall be suspended and the entire interest in
the Loans of the Defaulting Bank shall be subordinated to the interest of the
non-defaulting Bank and all payments or recoveries on the Loans received by
Administrative Agent from any source whatsoever that would otherwise be credited
by Administrative Agent to the Defaulting Bank shall instead be credited to the
non-defaulting Bank until full repayment is made to the non-defaulting Bank. In
addition, Administrative Agent shall be entitled to exercise any and all
remedies available to it at law or in equity against the Defaulting Bank.

         9A.8 Collections; Sharing of Payments.

                  (a) Administrative Agent, upon receipt, shall promptly
         distribute in like funds as received to each Bank its Pro Rata Share of
         all payments of principal, interest and fees (including without
         limitation any Letter of Credit Fees) received by Administrative Agent
         on or with respect to the Loans, whether collected from Borrower, or
         any security for the Loans, or otherwise, after first deducting any
         costs, fees or other charges due Administrative Agent hereunder or
         under the Credit Documents, with the exception of (i) the RLC "Non-Use
         Fee" of which Imperial shall receive one-half of its Pro Rata Share,
         (ii) the Termination Fee of which Imperial shall receive a share based
         on its share of the Total Commitment, and (iii) any charge for the
         administrative expenses of the Issuing Bank in connection with the
         Letters of Credit paid by Borrower pursuant to Section 2.12, which
         amounts shall be paid to the Issuing Bank.

                  (b) If any Bank shall receive and retain any payment, whether
         by set off, application of deposit balance or security, or otherwise,
         in respect of the obligations of Borrower hereunder in excess of such
         Bank's Pro Rata Share, then such Bank shall purchase from the other
         Bank (for cash and at face value and without recourse) such
         participation in the Loans held by it as shall be necessary to cause
         such excess payment to be shared ratably as aforesaid with the other
         Banks; provided, that if such excess payment or part thereof is
         thereafter recovered from such purchasing Bank, the related purchases
         from the other Bank shall be rescinded ratably and the purchase price
         restored as to the portion of such excess payments so recovered, but
         without interest.

         9A.9 Successor Administrative Agent. The Administrative Agent may
resign at any time by giving written notice thereof to the Banks and the
Borrower. Borrower and the Banks agree




                                      -69-

<PAGE>   76



to execute and deliver to such successor Administrative Agent such documents and
agreements as such successor Administrative Agent may require to carry out the
succession contemplated herein.

         9A.10 Issuing Bank. The Issuing Bank shall act on behalf of the Banks
with respect to any Letters of Credit Issued by it and the documents associated
therewith until such time and except for so long as the Administrative Agent may
agree at the request of all the Banks to act for such Issuing Bank with respect
thereto; provided, however, that the Issuing Bank shall have all of the benefits
and immunities (i) provided to the Administrative Agent in this Article 9A with
respect to any acts taken or omissions suffered by the Issuing Bank in
connection with Letters of Credit Issued by it or proposed to be Issued by it
and the application and agreements for letters of credit pertaining to the
Letters of Credit as fully as if the term "Administrative Agent," as used in
this Article 9A, included the Issuing Bank with respect to such acts or
omissions, and (ii) as additionally provided in this Senior Credit Agreement
with respect to the Issuing Bank.

of any provision of any Credit Document, or consent to any departure by Borrower
therefrom, shall be effective only if the same shall be in writing and accepted
by the Required Banks.

         10.2 Waiver. No failure to exercise, and no delay in exercising, on the
part of the Banks, any right hereunder shall operate as a waiver thereof, nor
shall any single or partial exercise thereof preclude any other further exercise
thereof or the exercise of any other right. The rights of the Banks and
Administrative Agent hereunder and under the Credit Documents shall be in
addition to all other rights provided by law. No modification or waiver of any
provision of this Senior Credit Agreement, the Notes or any Credit Documents,
nor consent to departure therefrom, shall be effective unless in writing and no
such consent or waiver shall extend beyond the particular case and purpose
involved. No notice or demand given in any case shall constitute a waiver of the

notice or demand.

the Banks and the Administrative Agent (including, without limitation,

enforcement of rights of the Banks and the Administrative Agent under this

however, that notwithstanding the aforesaid, with respect to any legal action
between the parties hereto that is pursued to judgment the prevailing party only

without limitation, reasonable attorneys' fees and costs) incurred in connection
with the preservation and enforcement of its rights under this Senior Credit
Agreement, the Notes and/or other Credit Documents. In addition, Borrower shall
pay all costs and expenses of the Banks and the Administrative Agent in

invalid or unenforceable provision or by its severance from such Credit
Document. Furthermore, in lieu of each such illegal, invalid or unenforceable
provision there shall be added as part of such Credit Document a provision
mutually agreeable to Borrower and the Banks as similar in terms to such
illegal, invalid or unenforceable provision as may be possible and be legal,
valid and enforceable.

         10.7 Binding Effect. The Credit Documents shall be binding upon and
inure to the benefit of Borrower, the Banks and the Administrative Agent and
their respective successors, assigns and legal representatives; provided,
however, that Borrower may not, without the prior written consent of the Banks,
assign any rights, powers, duties or obligations thereunder.

         10.8 Entirety. The Credit Documents embody the entire agreement between
the parties and supersede all prior agreements and understandings, if any,
relating to the subject matter hereof and thereof.

         10.9 Relationship of the Banks and Borrower. The Banks and Borrower
each have separate and independent rights and obligations under this Senior
Credit Agreement. Nothing




                                      -72-

contained herein shall be construed as creating, forming or constituting any
partnership, joint venture, merger or consolidation of Borrower and the Banks
for any purpose or in any respect.

         10.10 Time of the Essence. Time is expressly made of the essence of
this Senior Credit Agreement.

         10.11 Good Faith Standard. Except where governed by a specific
provision of this Senior Credit Agreement for a specific purpose, whenever the
approval or consent of the Banks is required hereunder, the Banks shall consider
the request for approval or consent on a timely basis, but the Banks shall have
such time as may be reasonably necessary to review and consider such request, as
determined in their sole judgment, and the Banks shall have the right to not
give their approval or consent or to impose such conditions or additional
requirements with respect to their approval or consent as the Banks in their
sole judgment shall determine. Approvals or consents by the Banks shall be
effective only when given in writing, except when otherwise specifically
provided herein. The standard by which the Banks shall be governed with respect
to a request for approval or consent shall be "good faith" as that term is
defined in the Arizona Uniform Commercial Code.

         10.12 Assignments and Participations; Transferees.

                  (a) This Senior Credit Agreement shall be binding upon and
         inure to the benefit of the parties hereto and their respective
         successors and assigns, except that the Borrower may not assign its
         rights or obligations hereunder, under any Note or under any other
         Credit Document without the prior written consent of all of the Banks.

                  (b) Each Bank may at any time grant participations in any
         portion of the Loans and Credit Documents owned by it to an Affiliate
         of such Bank without the consent of the other Banks. Otherwise each
         Bank may sell, assign, transfer or otherwise dispose of any portion of
         its interest therein (each such grant of a participation or interest so
         sold, assigned, transferred or disposed of being herein called a
         "Transferred Interest") to other financial institutions ("Transferees")
         only with the consent of the other Banks. In addition, each Bank may
         pledge any portion of its Notes for security purposes to any Federal
         Reserve Bank. Without in any way limiting the rights of Transferees
         hereunder, the Borrower agrees that each Transferee shall be entitled
         to the benefits of the Credit Documents to the extent of its
         Transferred Interest as if it were the "Bank" in an aggregate amount
         equal to such Transferred Interest, and that each Transferee may
         exercise any and all rights of banker's lien, setoff and counterclaim
         available pursuant to law with respect to its Transferred Interest as
         fully as if such Transferee were a direct lender to the Borrower.
         Borrower shall not be obligated to deal with or communicate with any
         such participant.

                  (c) As to any such assignment to a Transferee, (i) each such
         assignment shall be of a constant, and not a varying, percentage of all
         the assigning Bank's rights and obligations under this Senior Credit
         Agreement, (ii) the amount of the Commitment of the assigning Bank
         subject to each such assignment (determined as of the date the
         Assignment and Acceptance with respect to such assignment is delivered
         to the Administrative Agent) shall not be less than $1,000,000.00,
         (iii) the amount of the Commitment retained by the assigning Bank,
         unless the Assignment and Acceptance covers all or the remaining
         portion of the assigning Bank's interest, rights and obligations under
         this Senior Credit Agreement, after each such assignment shall not be
         less than $1,000,000.00, (iv) the parties to each such assignment shall
         execute and deliver to the Administrative Agent an Assignment and
         Acceptance, together with the Note or Notes subject to such assignment,
         and (v) the Transferee, if it shall not be a Bank, shall deliver to the
         Administrative Agent an Administrative Questionnaire. Upon acceptance
         and recording pursuant to paragraph (f) of this Section, from and after
         the effective date specified in each Assignment and Acceptance, (A) the
         Transferee thereunder shall be a party hereto and shall become a "Bank"
         hereunder, and, to the extent of the interest assigned by such
         Assignment and Acceptance, have all the rights and obligations of a
         Bank under this Senior Credit Agreement (including the obligation to
         arbitrate all controversies and claims, as required by Section 10.17
         hereof) and (B) the assigning Bank thereunder shall, to the extent of
         the interest assigned by such Assignment and Acceptance, be released
         from its obligations under this Senior Credit Agreement (and, in the
         case of an Assignment and Acceptance covering all or the remaining
         portion of an assigning Bank's rights and obligations under this Senior
         Credit Agreement, such Bank shall cease to be a party hereto (but shall
         continue to be entitled to the benefits of Sections 3.6, 3.7(b) and
         10.3).

                  (d) By executing and delivering an Assignment and Acceptance,
         the assigning Bank thereunder and the Transferee thereunder shall be
         deemed to confirm to and agree with each other and the other parties
         hereto as follows: (i) such assigning Bank warrants that it is the
         legal and beneficial owner of the interest being assigned thereby free
         and clear of any adverse claim and that its Commitment and the
         outstanding balances of its Loans, without giving effect to assignments
         thereof which have not become effective, are as set forth in such
         Assignment and Acceptance, (ii) except as set forth in (i) above, such
         assigning Bank makes no representation or warranty and assumes no
         responsibility with respect to any statements, warranties or
         representations made in or in connection with this Senior Credit
         Agreement, or the execution, legality, validity, enforceability,
         genuineness, sufficiency or value of this Senior Credit Agreement, any
         other Credit Document or any other instrument or document furnished
         pursuant hereto or the financial condition of the Borrower or the
         performance or observance by the Borrower of any of its obligations
         under this Senior Credit Agreement, any other Credit Document or any
         other instrument or document furnished pursuant hereto; (iii) such
         Transferee represents and warrants that it is 




                                      -74-

<PAGE>   81


         legally authorized to enter into such Assignment and Acceptance; (iv)
         such Transferee confirms that it has received a copy of this Senior
         Credit Agreement, together with copies of the most recent financial
         statements delivered pursuant to Section 7.1 and such other documents
         and information as it has deemed appropriate to make its own credit
         analysis and decision to enter into such Assignment and Acceptance; (v)
         such Transferee will independently and without reliance upon the
         Administrative Agent, such assigning Bank or any other Bank and based
         on such documents and information as it shall deem appropriate at the
         time, continue to make its own credit decisions in taking or not taking
         action under this Senior Credit Agreement; (vi) such Transferee
         appoints and authorizes the Administrative Agent to take such action as
         agent on its behalf and to exercise such powers under this Senior
         Credit Agreement as are delegated to the Administrative Agent by the
         terms hereof, together with such powers as are reasonably incidental
         thereto; and (vii) such Transferee agrees that it will perform in
         accordance with their terms all the obligations which by the terms of
         this Senior Credit Agreement are required to be performed by it as a
         Bank (including the obligation to arbitrate all controversies and
         claims, as required by Section 10.17 hereof).

                  (e) The Administrative Agent shall maintain at one of its
         offices in Phoenix, Arizona, a copy of each Assignment and Acceptance
         delivered to it and a register for the recordation of the names and
         addresses of the Banks, and the Commitment of, and principal amount of
         the Loans owing to, each Bank pursuant to the terms hereof from time to
         time (the "Register"). The entries in the Register shall be conclusive
         in the absence of manifest error and the Borrower, the Administrative
         Agent and the Banks may treat each Person whose name is recorded in the
         Register pursuant to the terms hereof as a Bank hereunder for all
         purposes of this Senior Credit Agreement. The Register shall be
         available for inspection by the Borrower and any Bank, at any
         reasonable time and from time to time upon reasonable prior notice.

                  (f) Upon its receipt of a duly completed Assignment and
         Acceptance executed by an assigning Bank and an Transferee together
         with the Note or Notes subject to such assignment, an Administrative
         Questionnaire completed in respect of the Transferee (unless the
         Transferee shall already be a Bank hereunder), the Administrative Agent
         shall (i) accept such Assignment and Acceptance, (ii) record the
         information contained therein in the Register, and (iii) give prompt
         notice thereof to the Banks. Within five Business Days after receipt of
         notice, the Borrower, as applicable, shall execute and deliver to the
         Administrative Agent, in exchange for the surrendered Note or Notes, a
         new Note or Notes to the order of such assigning Bank in a principal
         amount equal to the applicable Commitment retained by it. Such new Note
         or Notes shall be in an aggregate principal amount equal to the
         aggregate principal amount of such surrendered Note or Notes; such new
         Notes shall be dated the date of the surrendered Notes which they
         replace and shall otherwise be in substantially the applicable form of
         Exhibit "D" hereto.

         10.13 Headings. Section headings are for convenience of reference only
and shall in no way affect the interpretation of this Senior Credit Agreement.

         10.14 Survival. All representations and warranties made by Borrower
herein shall survive delivery of the Notes and the making of the Loans.

         10.15 No Third Party Beneficiary. The parties do not intend the
benefits of this Senior Credit Agreement to inure to any third party, nor shall
this Senior Credit Agreement be construed to make or render the Banks and the
Administrative Agent liable to any materialman, supplier, contractor,
subcontractor, purchaser or lessee of any property owned by Borrower, or for
debts or claims accruing to any such persons against Borrower. Notwithstanding
anything contained herein or in the Notes, or in any other Credit Document, or
any conduct or course of conduct by any or all of the parties hereto, before or
after signing this Senior Credit Agreement or any of the other Credit Documents,
neither this Senior Credit Agreement nor any other Credit Document shall be
construed as creating any right, claim or cause of action against the Banks and
the Administrative Agent, or any of their officers, directors, agents or
employees, in favor of any materialman, supplier, contractor, subcontractor,
purchaser or lessee of any property owned by Borrower, nor to any other person
or entity other than Borrower.

         10.16 Schedules and Exhibits Incorporated. All schedules and exhibits
attached hereto are hereby incorporated into this Senior Credit Agreement by
each reference thereto as if fully set forth at each such reference.

         10.17 Setoff. The Banks are hereby authorized at any time and from time
to time, without prior notice to Borrower (any such notice being expressly
waived by the Borrower), to set off and apply any and all deposits (general or
special, time or demand, provisional or final) at any time held by the Banks, or
any branch, subsidiary, or affiliate of the Banks, and other indebtedness at any
time owing by the Banks, or any branch, subsidiary, or affiliate of the Banks,
to or for the credit or the account of Borrower, against any and all of the
obligations of Borrower now or hereafter existing under the Credit Documents,
irrespective of (i) whether or not the Banks shall have made any demand under
the Credit Documents and (ii) whether such obligations are contingent, matured,
or unmatured. The Banks agree promptly to notify Borrower after any such setoff
and application, provided that the failure to give such notice shall not affect
the validity or such setoff and application. The rights of the Banks under this
Section are in addition to other rights and remedies (including, without
limitation, other rights of setoff) which the Banks may have.

         10.18 Arbitration. The Banks, the Administrative Agent and Borrower
agree that upon the written demand of either party, whether made before or after
the institution of any legal proceedings, but prior to the rendering of any
judgment in that proceeding, all disputes, claims and controversies between
them, whether individual, joint, or class in nature, arising from this Senior
Credit Agreement, any Credit Document or otherwise, including without limitation
contract disputes and tort claims, shall be resolved by binding arbitration
pursuant to the Commercial Rules of the American Arbitration Association
("AAA"). Any arbitration proceeding held



                                      -76-

<PAGE>   83


pursuant to this arbitration provision shall be conducted in the city nearest
the Borrower's address having an AAA regional office, or at any other place
selected by mutual agreement of the parties. No act to take or dispose of any
property shall constitute a waiver of this arbitration agreement or be
prohibited by this arbitration agreement. This arbitration provision shall not
limit the right of either party during any dispute, claim or controversy to
seek, use, and employ ancillary, or preliminary rights and/or remedies, judicial
or otherwise, for the purposes of realizing upon, preserving, protecting,
foreclosing upon or proceeding under forcible entry and detainer for possession
of, any real or personal property, and any such action shall not be deemed an
election of remedies. Such remedies include, without limitation, obtaining
injunctive relief or a temporary restraining order, invoking a power of sale
under any deed of trust or mortgage, obtaining a writ of attachment or
imposition of a receivership, or exercising any rights relating to personal
property, including exercising the right of set-off, or taking or disposing of
such property with or without judicial process pursuant to the Uniform
Commercial Code. Any disputes, claims or controversies concerning the lawfulness
or reasonableness of an act, or exercise of any right or remedy concerning any
property, including any claim to rescind, reform, or otherwise modify any
agreement relating to the property, shall also be arbitrated; provided, however
that no arbitrator shall have the right or the power to enjoin or restrain any
act of either party. Judgment upon any award rendered by any arbitrator may be
entered in any court having jurisdiction. The statute of limitations, estoppel,
waiver, laches and similar doctrines which would otherwise be applicable in an
action brought by a party shall be applicable in any arbitration proceeding, and
the commencement of an arbitration proceeding shall be deemed the commencement
of any action for these purposes. The Federal Arbitration Act (Title 9 of the
United States Code) shall apply to the construction, interpretation, and
enforcement of this arbitration provision.

         10.19 JURY WAIVER. THE BORROWER, THE BANKS AND THE ADMINISTRATIVE AGENT
HEREBY VOLUNTARILY, KNOWINGLY, IRREVOCABLY AND UNCONDITIONALLY WAIVE ANY RIGHT
TO HAVE A JURY PARTICIPATE IN RESOLVING ANY DISPUTE (WHETHER BASED UPON
CONTRACT, TORT OR OTHERWISE) BETWEEN OR AMONG THE BORROWER AND THE BANKS AND THE
ADMINISTRATIVE AGENT ARISING OUT OF OR IN ANY WAY RELATED TO THIS DOCUMENT, ANY
OTHER CREDIT DOCUMENT, OR ANY RELATIONSHIP BETWEEN THE BANKS, THE ADMINISTRATIVE
AGENT AND THE BORROWER. THIS PROVISION IS A MATERIAL INDUCEMENT TO THE BANKS TO
PROVIDE THE FINANCING DESCRIBED HEREIN OR IN THE OTHER CREDIT DOCUMENTS.
