INTRODUCTION

        Granite Construction Incorporated, the "Company" or "Granite," was
incorporated in Delaware in January 1990 as the holding company for Granite
Construction Company, which was incorporated in California in 1922. Therefore,
references herein to the "Company" or "Granite" in the context of operations
should be read to mean Granite Construction Company and Granite Construction
Incorporated's other subsidiaries.

        The Company is one of the largest heavy civil construction contractors
in the United States and operates nationwide. Its focus is primarily in the
west, southwest, and southeast serving both public and private sector clients.
Within the public sector, the Company concentrates on infrastructure projects;
including the construction of roads, highways, bridges, dams, tunnels, canals,
mass transit facilities and airports. Within the private sector, the Company
performs site preparation services for buildings, plants, subdivisions and other
facilities. Granite's participation in both the public and private sectors and
its diverse mix of project types and sizes have contributed to the Company's
revenue growth and profitability in various economic environments.

        The Company owns and leases substantial aggregate reserves and owns 108
construction materials processing plants. The Company also owns one of the
largest heavy construction contractor equipment fleets in the United States. The
Company believes that the ownership of these assets enables it to compete more
effectively by ensuring availability of these resources at a favorable cost.

OPERATING STRUCTURE

        The principal operating company, Granite Construction Company, is
organized into two business segments, the Branch Division and the Heavy
Construction Division. The Branch Division is comprised of branch offices which
serve local markets, while the Heavy Construction Division pursues major
infrastructure projects throughout the nation. The Heavy Construction Division
("HCD") generally builds large heavy civil projects with contract amounts in
excess of $15 million and contract durations greater than two years, while the
Branch Division projects are typically smaller in size and shorter in duration.





                                       3
<PAGE>   4


     The two divisions complement each other in a variety of ways. The Heavy
Construction Division is a major user of large construction equipment and
employs sophisticated techniques on complex projects. The branches draw on these
resources which are generally not available to smaller, local competitors.
Conversely, the Branch Division has greater knowledge of local markets and
provides the Heavy Construction Division with valuable information regarding
larger projects in the branches' areas. The two divisions sometimes jointly
perform projects when a project in a particular region exceeds the local
branch's capabilities.

     As decentralized profit centers, the branch offices and the Heavy
Construction Division independently estimate, bid and complete contracts. Both
divisions are supported by centralized functions, including finance, accounting,
tax, human resources, labor relations, safety, legal, insurance, surety and
management information services. The Company believes that centralized support
for decentralized profit centers results in a more market responsive business
with effective controls and reduced overhead.

     In addition to cost and profitability estimates, Granite considers the
availability of estimating and project building personnel as key factors when
determining whether to bid on a project. Other factors considered include the
client, the geographic location, Granite's competitive advantages and
disadvantages relative to likely competitors for the project, current and
projected workload, and the likelihood of follow-up work. Both operating
divisions use a proprietary computer-based project estimating system that
reflects Granite's significant accumulated experience. Granite believes that an
exhaustive, detailed approach to a project's estimate and bid is important in
order to best identify the project's risks and opportunities. The Company's
estimates are comprehensive in nature, sometimes totaling hundreds of pages of
analysis. Each project is broken into phases and line items, for which separate
labor, equipment and material estimates are made. Once a project begins, the
estimate provides Granite with a budget against which actual project cost is
regularly measured, enabling Granite to manage its projects more effectively.

     Information about the Company's business segments for the years ended
December 31, 1998, 1997 and 1996 is incorporated in Note 14 of the "Notes to the
Consolidated Financial Statements," located on page F-17 of this Annual Report
on Form 10K.

     The Branch Division. In 1998, Branch Division contract revenue and sales of
aggregate products were $945.9 million (77.1% of Company revenue) as compared
with $831.9 million (80.9% of Company revenue) in 1997. The Branch Division has
both public and private sector clients. Public sector activities include both
new construction and improvement of streets, roads, highways and bridges. For
example, the branches widen and re-pave roads and modify and replace bridges.
Major private sector contracts include site preparation for housing, including
excavation; grading and street paving; and installation of curbs, gutters,
sidewalks and underground utilities.

     The Company currently has 11 branch offices with 14 satellite operations.
The Company's branch offices in California are located in Bakersfield, Hanford
(Central Valley), Monterey Bay Area, Palm Springs (Southern California Region),
Sacramento, San Jose, Santa Barbara and Stockton. The Company's branch offices
outside of California are located in Arizona, Nevada and Utah. Each branch
effectively operates as a local or regional construction company and its
management is encouraged to participate actively in the local community. While
individual branch revenues vary from year to year, in 1998 these revenues ranged
from $41 million to $187 million.

     As part of the Company's strategy, many of Granite's branches mine
aggregates and operate plants which process aggregates into construction
materials for internal use and for sale to others. These activities provide both
a source of profits and a competitive advantage to the Company's construction
business. Close to half of the aggregate products are used in the Company's
construction projects. The remainder is sold to unaffiliated parties and
accounted for $141.7 million of revenue in 1998, representing 11.6% of the
Company's total 1998 revenue. The Company has significant aggregate reserves
which it has acquired by ownership in fee or through long-term leases. It is the
Company's objective to continue to own or lease adequate aggregate reserves.

     Heavy Construction Division. In 1998, revenue from HCD was $280.2 million
(22.9% of Company revenue) as compared with $196.3 million (19.1% of Company
revenue) in 1997. HCD projects are usually larger and more complex than those
performed by the Branch Division. The Division has completed projects throughout
the nation; including mass transit projects in the metropolitan areas of
Atlanta, Baltimore, Los Angeles, San Francisco and Washington, D.C., and 27
major dam and tunnel projects in eight states.

     HCD builds infrastructure projects; including major highways, large dams,
mass transit facilities, bridges, pipelines, canals, tunnels, waterway locks and
dams and airport runways, and has engaged in contract mine stripping and
reclamation and large site preparation. It also performs activities such as
demolition, clearing, excavation, de-watering, drainage, embankment fill,
structural concrete, concrete and asphalt paving, and tunneling.





                                       4
<PAGE>   5


     The Division markets, estimates, bids and provides management overview of
its projects from its Watsonville, California headquarters and satellite
estimating offices in Texas, Georgia, Florida and Maryland. Project staff
located at job sites have the managerial, technical, and clerical capacity to
meet on-site project management requirements. HCD has the ability, if
appropriate, to process locally sourced aggregates into construction materials
using its own portable crushing, concrete and asphalt processing plants.

     HCD participates in joint ventures with other large construction companies
from time to time. Joint ventures are used for large, technically complex
projects, including design/build projects, where it is desirable to share risk
and resources. Joint ventures provide independently prepared estimates, and
shared financing, equipment and expertise.

     Design/build projects have emerged as an expanding market for HCD. Unlike
traditional projects where owners first hire a design firm and then put the
plans out to bid to find a contractor, design/build projects provide the owner
with a single point of responsibility and a single contact. Past design/build
projects have included the SR-91 Tollway which was completed in 1995 and the San
Joaquin Hills Transportation Corridor which was completed in 1996. Ongoing
projects include the I-15 rebuild in Salt Lake City, Utah, the Atlantic
City/Brigantine Connector in New Jersey and a recently awarded I-17 rebuild
project in Phoenix, Arizona. Design/build projects have historically been bid
with the Company as part of a joint venture team. While design/build is being
used considerably more in the private sector, the public sector is expanding its
use.

INVESTMENT IN T.I.C. HOLDINGS, INC.

     The Company holds a 30% minority interest in T.I.C. Holdings, Inc. ("TIC")
as part of its diversification strategy (See Business Strategy). TIC, founded in
1974, is one of the leading merit shop general heavy industrial contractors in
the U.S. TIC performs all major disciplines including civil, structural steel
erection, heavy mechanical, process piping and electrical/instrumentation. TIC
has offices in Colorado, Georgia, California, Texas, Louisiana, Kansas, Nevada,
Oregon and Wyoming. TIC operates both nationally and internationally. TIC had
annual revenue of $534 million in 1998. By market sector 52% of its 1998 revenue
came from industrial/petrochemical projects, 26% from water/sewer/wastewater
projects, 18% from power-related projects and the remaining 4% from
transportation-related and other work.

BUSINESS STRATEGY

     Granite's fundamental objective is to increase long-term shareholder value
by focusing on consistent profitability from carefully managed revenue growth.
Shareholder value is measured by the appreciation of the value of Granite stock
over a period of years, and to some degree, a return from dividends. Further, it
is a specific measure of the Company's financial success to achieve a Return on
Net Assets ("RONA") greater than the cost of capital, creating "Granite Value
Added." To accomplish these objectives, Granite employs the following
strategies:

     Heavy/Highway Construction Focus - Granite concentrates its core
     competencies on this segment of the construction industry which includes
     the building of roads, highways, bridges, dams and tunnels, mass transit
     facilities and site preparation. This focus emphasizes the Company's
     specialized strengths which include earth moving, grading, paving and
     concrete structures.

     Vertical Integration of Aggregate Materials into Construction - Granite
     owns aggregate reserves and processing plants and thus, by ensuring
     availability of these resources at favorable cost, it believes it has
     significant bidding advantages in many of its markets.

     Selective Bidding - Once Granite selects a job that meets its bidding
     criteria, the project is estimated using a highly detailed method with a
     proprietary estimating system which applies both contingency cost and
     margin to achieve the appropriate profit margin for the risk assumed.

     Diversification - To mitigate the risks inherent in construction and
     general economic factors, Granite pursues projects (i) in both the public
     and private sectors; (ii) for a wide range of customers within each sector
     (from the federal government to small municipalities and from large
     corporations to individual homeowners); (iii) in diverse geographic
     markets; (iv) of various sizes, durations and complexity; and (v) in the
     heavy industrial market segment.




                                       5
<PAGE>   6

     Decentralized Profit Centers - Granite addresses each selected market with
     a highly customer responsive organization through its decentralized
     structure. Each of Granite's branches and the Heavy Construction Division
     are individual profit centers.

     Management Incentives - The Company compensates its profit center managers
     with lower-than-market fixed salaries coupled with a substantial variable
     cash and restricted stock incentive element based on the annual profit
     performance of their respective profit centers.

     Ownership of Construction Equipment - By owning and carefully maintaining a
     large fleet of heavy construction equipment, Granite essentially operates
     an internal leasing company and therefore competes more effectively by
     ensuring availability of these resources at favorable cost.

     Controlled Expansion - The Company intends to continue its geographic
     expansion by selectively adding branches in the western United States,
     pursuing major infrastructure projects throughout the nation and expanding
     into other construction market segments through acquisitions.

     Accident Prevention - Granite believes that the prevention of accidents is
     both a moral obligation and good business. By identifying and preventing
     potential accidents, the Company continues to significantly reduce the
     costs associated with accidents.

     Environmental Affairs - Granite believes it benefits everyone to maintain
     environmentally responsible operations. The Company is committed to
     effective air quality control measures and reclamation at its plant sites
     and to waste reduction and recycling of the environmentally sensitive
     products used in its operations.

     Quality and High Ethical Standards - Granite emphasizes the importance of
     performing high quality work and maintaining high ethical standards through
     an established code of conduct and an effective corporate compliance
     program.

CUSTOMERS

     The Company has customers in both the public and private sectors. The
Branch Division's principal customers are state departments of transportation in
California, Utah, Nevada, and Arizona and the US Army Corp. of Engineers. In
1998, contracts with the California Department of Transportation represented
11.6% of the Company's revenue. Other Branch Division clients include county and
city public works departments and developers and owners of industrial,
commercial and residential sites. The principal clients of the Heavy
Construction Division are in the public sector and currently include the U.S.
Bureau of Reclamation and the State Departments of Highways and Public
Transportation in Utah, Texas, Florida, and New Jersey. Total Company contracts
(including the Company's share of a construction joint venture) with the Utah
Department of Transportation represented 11.3% of the Company's revenue in 1998.
(See Note 2 of Notes to Consolidated Financial Statements).

existing contracts) was $901.6 million at December 31, 1998, down from $909.8
million at December 31, 1997, and was $597.9 million at December 31, 1996.
Approximately $260 million of the December 31, 1998 backlog is expected to
remain at December 31, 1999. The Company includes a construction project in its
backlog at such time as a contract is awarded or a firm letter of commitment is
obtained and funding is in place. (See "Management's Discussion and Analysis of
Financial Condition and Results of Operations.") The Company believes its
backlog figures are firm, subject only to the cancellation and modification
provisions contained in various contracts. Substantially all of the contracts in
the backlog may be canceled or modified at the election of the client. However,
the Company has not been materially adversely affected by contract cancellations
or modifications in the past. (See "Business-Contract Provisions and
Subcontracting.") A sizeable percentage of the Company's anticipated revenue in
any year is not reflected in its backlog at the start of the year due to the
short duration of smaller Branch Division projects that are initiated and
completed during such year ("Turn Business"). The following is a breakdown of
backlog as of December 31, 1998, 1997 and 1996 (in millions):

EQUIPMENT

     The Company purchases and maintains many pieces of equipment; including
cranes, bulldozers, scrapers, graders, loaders, trucks, pavers, rollers, and
construction materials processing plants. In 1998 and 1997, the Company spent
approximately $41.2 million and $45.4 million, respectively, for construction
equipment, plants and vehicles. The breakdown of the Company's construction
equipment, plants and vehicles at December 31, 1998 is as follows:

<TABLE>
<S>                                                            <C>        
     Heavy construction equipment ........................      2,349 units
     Trucks, truck-tractors and trailers and vehicles ....      2,965 units
     Aggregate crushing plants ...........................      38 plants
     Asphalt concrete plants .............................      43 plants
     Portland cement concrete batch plants ...............      25 plants
     Thermal Soil Remediation Plants .....................      2 plants
</TABLE>

     The Company believes that ownership of equipment is preferable to leasing
because ownership ensures the equipment is available as needed and normally
results in lower equipment costs. The Company attempts to keep its equipment as
fully utilized as possible by pooling equipment for use by both the Branch
Division and the Heavy Construction Division. From time to time, the Company
leases or rents equipment on a short-term basis.

EMPLOYEES

     On December 31, 1998, Granite employed 1,101 salaried employees, who work
in management, estimating and clerical capacities, and 2,760 hourly employees.
The total number of hourly personnel employed by the Company is subject to the
volume of construction in progress. During 1998, the number of hourly employees
ranged from 2,254 to 4,357 and averaged approximately 3,388. The Company's
wholly owned subsidiary, Granite Construction Company, is a party to craft
collective bargaining agreements in many areas in which it is working.

     The Company believes its employees are its most valuable resource and that
its workforce possesses a strong dedication to and pride in the Company. Among
salaried and non-union hourly employees, this dedication is reinforced by 32%
equity ownership through the Employee Stock Ownership Plan ("ESOP") and
performance-based incentive compensation arrangements. The Company's 371
managerial and supervisory personnel have an average of 11 years of service with
Granite.

COMPETITION

     Factors influencing the Company's competitiveness are price, reputation for
quality, the availability of aggregate materials, machinery and equipment,
financial strength, knowledge of local markets and conditions, and estimating
abilities. The Company believes that it competes favorably on the basis of the
foregoing factors. Branch Division competitors range from small local
construction companies to large regional construction companies. While the
market areas of these competitors overlap with several of the markets served by
the Company's branches, few, if any, compete in all of the Company's market
areas. The Heavy Construction Division normally competes with large regional and
national construction companies. Although the construction business is highly
competitive, particularly for competitively bid projects in the public sector,
the Company believes it is well positioned to compete effectively.

CONTRACT PROVISIONS AND SUBCONTRACTING

     The Company's revenue is substantially derived from contracts that are
"fixed unit price" contracts under which the Company is committed to provide
materials or services required by a project at fixed unit prices (for example,
dollars per cubic yard of concrete or cubic yards of earth excavated). While the
fixed unit price contract shifts the risk of estimating the quantity of units
required for a particular project to the customer; any increase in the Company's
unit cost over the unit price bid, whether due to inflation, inefficiency,
faulty estimates or other factors, is borne by the Company unless otherwise
provided in the contract. The Company's contracts are obtained primarily through
competitive bidding in response to advertisements by federal, state and local
government agencies and private parties.

     All federal government contracts and many of the Company's other contracts
provide for termination of the contract for the convenience of the party
contracting with the Company. In addition, many of the Company's contracts are
subject to certain completion schedule requirements with liquidated damages in
the event schedules are not met. The Company has not been materially adversely
affected by these provisions in the past.

     The Company acts as prime contractor on most of the construction projects
it undertakes. The Company accomplishes the majority of its projects with its
own resources and subcontracts specialized activities such as electrical and
mechanical work. As prime contractor the Company is responsible for the
performance of the entire contract, including subcontract work. Thus, the
Company is subject to increased costs associated with the failure of one or more
subcontractors to perform as anticipated. The Company's subcontractors generally
furnish bonds which provide an additional measure of security of their
performance. Disadvantaged business enterprise regulations require the Company
to use its best efforts to subcontract a specified portion (historically ranging
up to 25%) of contract work done for governmental agencies to certain types of
subcontractors. Some of these subcontractors may not be able to obtain surety
bonds. The Company has not incurred any material loss or liability on work
performed by subcontractors to date.

INSURANCE AND BONDING

     The Company maintains general and excess liability, construction equipment,
and workers' compensation insurance; all in amounts consistent with industry
practices. Management believes its insurance programs are adequate.

     In connection with its business, the Company generally is required to
provide various types of surety bonds which provide an additional measure of
security of its performance under certain public and private sector contracts.
The Company's ability to obtain surety bonds depends upon its capitalization,
working capital, past performance, management expertise and other factors.
Surety companies consider such factors in light of the amount of surety bonds
then outstanding for the Company and their current underwriting




                                       8
<PAGE>   9


standards, which may change from time to time. The Company has been bonded by
the same surety for more than 60 years and has never been refused a bond.

GOVERNMENT REGULATIONS

     The Company's operations are subject to compliance with regulatory
requirements of federal, state, and municipal agencies and authorities;
including regulations concerning labor relations, affirmative action and the
protection of the environment. While compliance with applicable regulatory
requirements has not adversely affected the Company's operations in the past
relative to its competitive position within its industry sector, there can be no
assurance that these requirements will not change and that compliance will not
adversely affect the Company's operations. In addition, the aggregate materials
operations of the Company require operating permits granted by governmental
agencies. The Company believes that tighter regulations for the protection of
the environment and other factors will make it increasingly difficult to obtain
new permits and renewal of existing permits may be subject to more restrictive
conditions than currently exist.

ITEM 2.  PROPERTIES

     The Company owns and leases real property for use in its construction and
aggregate mining and processing activities. The Company owns approximately
394,300 square feet of office and shop space and leases, pursuant to leases
expiring between January 1999 and April 2003, an additional 44,800 square feet
of office and shop space. The Company owns approximately 10,700 acres of land of
which 1,600 acres are un-permitted reserves available for future use and leases
approximately 4,636 additional acres of land at sites in California, Nevada,
Arizona and Utah. A majority of the land owned or leased by the Company is
intended to serve as aggregate reserves. There are no significant encumbrances
against owned property. The Company's leases for aggregate reserves generally
limit the Company's interest in the reserves to the right to mine the reserves.
These leases range from month-to-month leases to leases with expiration dates
ranging from January 1999 to January 2016. The Company considers its available
and future aggregate reserves adequate to meet operating needs. The Company
pursues a plan of acquiring new sources of aggregate reserves to replenish those
depleted and to assure future growth.


ITEM 3.  LEGAL PROCEEDINGS

     The Company is a party to a number of legal proceedings. The Company
believes that the nature and number of these proceedings are typical for a
construction firm of its size and scope and that none of these proceedings is
material to the Company's financial position.


ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

     The Company has not submitted any matters to a vote of security holders
during the fourth quarter of the year ended December 31, 1998.

ITEM 5. MARKET FOR THE REGISTRANT'S COMMON STOCK AND RELATED STOCKHOLDER MATTERS

     On April 25, 1997, the Company commenced trading its common stock on the
New York Stock Exchange under the ticker symbol GVA. The Company's move from
NASDAQ Stock Market to the New York Stock Exchange was intended to improve
trading efficiencies and liquidity in an effort to promote enhanced shareholder
value. See Quarterly Results in Item 7 for a two-year summary of quarterly
dividends and high and low sales prices of the Company's stock.

     The Company expects to pay a quarterly cash dividend of $0.07 plus a
special dividend of $0.12 per share of common stock to stockholders of record as
of March 31, 1999 payable on April 16, 1999 (See Note 15 of Notes to
Consolidated Financial Statements). Declaration and payment of dividends is
within the sole discretion of the Company's Board of Directors, subject to
limitations imposed by Delaware law, and will depend on the Company's earnings,

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS

GENERAL

        Granite is one of the largest heavy civil contractors in the United
States and is engaged in the construction of highways, dams, airports, mass
transit facilities and other infrastructure-related projects. The Company has
offices in California, Texas, Georgia, Nevada, Arizona, Florida, Oregon,
Maryland and Utah.

        The Company's contracts are obtained primarily through competitive
bidding in response to advertisements by federal, state and local agencies, and
private parties. The Company's bidding activity is affected by such factors as
backlog, current utilization of equipment and other resources, ability to obtain
necessary surety bonds and competitive considerations. Bidding activity, backlog
and revenue resulting from the award of new contracts to the Company may vary
significantly from period to period.

        Revenue from construction contracts including construction joint
ventures is recognized using the percentage-of-completion method of accounting,
based upon costs incurred and projected costs. Revenue in an amount equal to
cost incurred is recognized prior to contracts reaching 25% completion. The
related earnings are not recognized until the period in which such percentage
completion is attained. Cost of revenue consists of direct costs on contracts;
including labor and materials, amounts payable to subcontractors, direct
overhead costs, equipment expense (primarily depreciation, maintenance and
repairs) and insurance costs. Depreciation is provided using accelerated methods
for construction equipment. Contracts frequently extend over a period of more
than one year and revisions in cost and profit estimates during construction are
reflected in the accounting period in which the facts that require the revision
become known. Losses on contracts, if any, are provided in total when
determined, regardless of the degree of project completion. Claims for
additional contract revenue are recognized in the period when it is probable
that the claim will result in additional revenue and the amount can be reliably
estimated. The foregoing as well as weather, stage of completion, and mix of
contracts at different margins may cause fluctuations in gross profit between
periods.

        The Company's compensation strategy for selected management personnel is
to rely heavily on a variable cash and restricted stock performance-based
incentive element. Thus, the Company may experience an increase in general and
administrative expenses in a very profitable year and a decrease in less
profitable years. The Company's pension contribution in excess of the 401K
matching contributions is at the discretion of the Board of Directors based on
the Company reaching certain levels of profitability each year.

CURRENT YEAR

        REVENUE AND BACKLOG. During the year ended December 31, 1998, revenue
increased $197.9 million (19.2%) to $1.226 billion. The Branch Division revenue
increased $114.0 million to $945.9 million in 1998, from $831.9 million in 1997.
The Branch Division increase is due primarily to improved market conditions
(particularly in the private sector), and to a lesser extent, contributions made
from flood related emergency work caused by severe winter weather conditions.
Heavy Construction Division (HCD) revenue increased $83.9 million to $280.2
million in 1998, from $196.3 million in 1997 which reflects increased revenue
from HCD's portion of the Company's Interstate - 15 rebuild project in Utah and
various projects added to backlog in 1998. The Company's revenue from public
sector contracts increased to $836.0 million in 1998 from $726.6 million in 1997
while decreasing to 68.2% of the Company's total revenue in 1998 from 70.6% in
1997. Revenue from private sector contracts increased $73.9 million to $248.4
million or 20.2% of total revenue in 1998, from $174.5 million or 17.0% of total
revenue in 1997.

        The Company's backlog at December 31, 1998 was $901.6 million, down $8.2
million, or 0.9% from 1997. The relatively flat backlog in 1998 reflects new
awards which offset a reduction due to a full year's work on the Company's 23%
share of the I-15 Corridor Reconstruction project in Salt Lake City, Utah which
was awarded in the first quarter of 1997. Work on our $313 million portion of
the contract began during the second quarter of 1997 and was approximately 48%
complete at the end of 1998. Management believes that approximately 71% of the
work in the backlog at December 31, 1998 will be recognized as revenue during
1999. The Company believes its bidding opportunities in its major marketplaces
remain strong (see "Outlook").





                                       14
<PAGE>   15



        GROSS PROFIT. For the year ended December 31, 1998, gross profit reached
$153.1 million, a $41.4 million increase from 1997. As a percentage of revenue,
gross profit increased in 1998 to 12.5% from 10.9% in 1997. The increased gross
profit margin reflects the current favorable market conditions as well as the
Company's Interstate- 15 rebuild project which reached the 25% completion
threshold for profit recognition during the second quarter of 1998. Revenue in
an amount equal to cost incurred is recognized prior to contracts reaching 25%
completion.

        GENERAL AND ADMINISTRATIVE EXPENSES. General and administrative expenses
include salaries, incentive compensation, retirement plans, costs associated
with the Company's estimating and bidding activities, and other administrative
costs. General and administrative expenses increased from $73.6 million in 1997
to $83.8 million in 1998 and decreased from 7.2% of revenue in 1997, to 6.8% of
revenue in 1998. The dollar increase is primarily due to higher profit sharing,
incentive compensation and other costs resulting from the Company's increased
revenue and bidding activities partially offset by the collection of a
previously written-off bad debt. The decrease as a percent of revenue is due to
the fixed nature of certain expenses and higher revenue from non-sponsored joint
venture contracts which do not create a corresponding level of administrative
expense.

        OPERATING INCOME. The Branch Division's contribution to operating income
in 1998 increased over the 1997 contribution due primarily to improved market
conditions which increased both the volume of work and the profit margins the
Division was able to achieve. The Heavy Construction Division's contribution to
operating income also increased in 1998, primarily due to the impact of the I-15
project reaching the 25% completion threshold for profit recognition as
described above.

        OTHER INCOME (EXPENSES). Other income decreased $0.2 million to $5.8
million in 1998. The decrease was due to an increase in interest expense
resulting from additional borrowings under long-term debt agreements and lower
gain on sale of property and equipment which was partially offset by higher
interest income due to higher short-term investments and cash and cash
equivalents.

        OUTLOOK. As we enter 1999, the Company's fundamental business outlook
remains very favorable, based on record levels of public infrastructure funding
and healthy economic conditions in many of the Company's geographic
marketplaces.

        TEA-21, as we have noted in the past, is the federal transportation bill
that will act as a flywheel to drive the various state highway programs for the
next five plus years. According to the U.S. Department of Transportation,
California, the Company's largest market, is expected to see a 45.6% increase in
funding during this period over the previous authorizing legislation for surface
transportation. Moreover, Texas and Florida, two additional states where we are
actively bidding and building work, anticipate funding increases of 60.7% and
57.3% during this period, respectively, also according to the U.S. Department of
Transportation. We should caution investors, however, that the opportunities
that TEA-21 will provide for contractors such as Granite are just beginning to
emerge. Because the cycle for federal money to progress from planning to design
to actual construction bids takes time, we most likely will not see any
significant increase in bidding opportunities until mid-1999 at the earliest.
Therefore, considering that profits on a job are not recognized until it is 25%
complete, we would not anticipate any meaningful boost to our bottom line from
TEA-21-funded projects until the year 2000 and beyond. However we believe there
will be ample bidding opportunities in the first half of the year from other
sources.

        Increased public infrastructure funding is also getting renewed
attention in California, where leaders from both parties in both the Assembly
and the Senate have proposed a package of multi-billion-dollar bills ranging
from bond issues to dedicating a quarter cent of the existing sales tax toward
the renovation and construction of roads, bridges and other public facilities.
In fact, Governor Davis in early March appointed a select committee on
infrastructure, a major focus of which will be transportation.

        Aside from increased bidding opportunities, we believe increased public
highway funding will help advance the design-build segment of our industry.
Highway departments are increasingly sensitive to the public demand to complete
projects in the shortest time possible. Mega design-build projects like HCD's
I-15 reconstruction joint venture in Salt Lake City, Utah give clients many cost
and time advantages and in return offer us the opportunity to earn higher than
normal gross profit margins, if we execute the work successfully. A further
example of the benefit to the Company is the recent award of a design-build
project in Arizona which allowed that state to expedite the use of available
TEA-21 monies.

        Additionally, increased bidding opportunities fueled by additional
transportation dollars should give both of our divisions the increased latitude
to be more selective in targeting those bidding opportunities that meet the
Company's profitability objectives. Specifically, our Heavy Construction
Division has targeted several design-build projects to bid this year, including
a bridge replacement project in Florida, major wharf improvements in South
Carolina and a water storage project in Massachusetts. HCD will again be
actively bidding on transportation projects in its core markets of Texas and
Florida and plans to step up its bidding



                                       15
<PAGE>   16


efforts in new markets including Pennsylvania and the Carolinas. HCD and TIC,
our strategic industrial partner, plan to joint venture a number of
opportunities this year, including merchant power and wastewater treatment
projects.

        Looking ahead at the private component of our business, we are
encouraged by the underlying strength of California's economic base. According
to the Center for the Continuing Study of the California Economy, the state
added 400,000 new jobs in 1998. As a result, California's unemployment rate fell
to 5.7%, the lowest level since before the 1990 recession. Furthermore,
construction spending grew at double digit rates in 1998, the Center noted.
Housing markets continued to improve moderately in 1998, the economists noted,
although the 125,000 new units built in 1998 were still less than half of
mid-1980s building levels. To date, we have not seen any significant impact on
the California construction marketplace from the economic crisis afflicting Asia
and South America. We should remind investors that our business focus is the
domestic marketplace, thus we have no exposure to delays or cancellations of
overseas projects unlike some companies in our industry.

        A healthy private and public California marketplace should provide a
strong bidding climate for our Branch Division. The California Department of
Transportation expects increased funding from TEA-21 to impact its bidding
schedules beginning this summer. Arizona has already seen an impact from TEA-21
funding. Private and public markets are also expected to stay strong in Nevada
and Utah in 1999.

        We will not, however, benefit financially in 1999 from two separate
events that contributed to our success in 1998. Absent in 1999 will be a
one-time boost to earnings of the magnitude that the Company received when the
I-15 rebuild project in Utah reached the 25% completion threshold in the second
quarter of 1998. Secondly, the Company in 1999 will not benefit from emergency
work resulting from El Nino that helped the first and second quarters in 1998.

        Finally, the Company remains focused on growth both internally and
externally. We believe we are working to carry out a strategic plan that puts us
in the right place at the right time to capitalize on the exciting opportunities
ahead of us. We will continue to work our plan, focusing on profitable growth
through expanding internal operations and strategic acquisitions in an effort to
provide an optimal level of value to our stockholders.

PRIOR YEARS

        REVENUE AND BACKLOG. During the year ended December 31, 1997, revenue
increased $99.4 million (10.7%) to $1.028 billion. The increase in revenue is
associated with higher levels of bidding opportunities and awards in our Branch
Division. The Branch Division revenue increased $116.3 million to $831.9 million
in 1997, from $715.6 million in 1996. Heavy Construction Division (HCD) revenue
decreased $16.9 million to $196.3 million in 1997, from $213.2 million in 1996.
The Company's revenue from public sector contracts increased to $726.6 million,
or 70.6% of the Company's revenue in 1997, from $657.2 million, or 70.7% in
1996. Revenue from private sector contracts decreased $3.6 million to $174.5
million in 1997, and decreased from 19.2% of total revenue in 1996 to 17.0% of
total revenue in 1997.

        During the year ended December 31, 1996 revenue increased $34.0 million
(3.8%) to $928.8 million due to higher levels of bidding opportunities and
awards in our Branch Division and a full year of Utah Branch activity in 1996.
The Company's backlog at December 31, 1997 was $909.8 million, up $311.9
million, or 52.2% over the same period in 1996.

        GROSS PROFIT. For the year ended December 31, 1997, gross profit reached
$111.7 million, a $1.0 million increase from 1996. As a percentage of revenue,
gross profit decreased in 1997 to 10.9% from 11.9% in 1996, due in part to an
increase in revenue recognized for contracts that had not reached the 25%
completion threshold. Additionally, gross profit in 1997 reflected the absence
of the San Joaquin Hills Toll Road Project completed in late 1996 which carried
a higher than average gross profit margin.

        GENERAL AND ADMINISTRATIVE EXPENSES. General and administrative expenses
increased from $71.6 million, or 7.7% of revenue in 1996, to $73.6 million, or
7.2% of revenue in 1997. The increase reflects a higher level of costs to
support the Company's increased revenue and bidding activities and increased
personnel to support the Company's expansion into the South/East marketplace.



                                       16
<PAGE>   17



        OPERATING INCOME. The Branch Division's contribution to operating income
in 1997 increased over the 1996 contribution due primarily to increased revenue
driven by higher levels of bidding opportunities and awards. The Heavy
Construction Division's contribution to operating income decreased in 1997 as
compared to 1996, due in part to an increase in revenue recognized for contracts
that had not reached the 25% completion threshold. Additionally, HCD's operating
income in 1997 reflects the absence of the San Joaquin Hills Toll Road Project
completed in late 1996 which carried a higher than average gross profit margin.

        OTHER INCOME (EXPENSES). Other income increased $1.7 million to $6.0
million in 1997. The increase was due to an increase in the Company's equity in
the earnings of its affiliates partially offset by higher interest expense
associated with higher debt levels and a decrease in gains on sales of property
and equipment.

        During 1998, cash provided from operations of $96.0 million was
primarily used to purchase $52.5 million of property and equipment, to purchase
short-term investments and to pay dividends of $7.7 million. Changes in cash
provided by operating activities primarily reflect profitability and normal
variations in the cash flow on contracts and payables.

        The Company's practice has been to replace and replenish its equipment
fleet with cash generated from operations. Cash purchases of property and
equipment increased $4.1 million from 1997 to 1998 and $2.3 million from 1996 to
1997.

        On March 19, 1998 the Company issued Senior Notes in the amount of $60
million to a group of institutional holders. The notes are due in nine equal
annual installments beginning in 2002 and bear interest at 6.54% per annum. The
Company used $39 million of the proceeds of the notes to retire its bank
revolving credit notes.

        On March 17, 1999, the Board of Directors authorized the Company to
repurchase, at management's discretion, up to $35 million of its common stock on
the open market, exclusive of repurchases related to employee benefit plans.
This authorization amends an authorization previously made in March of 1997.
Through March 26, 1999 581,050 shares have been repurchased for a total purchase
price of $13.7 million, including 561,400 shares repurchased subsequent to
December 31, 1998. The remaining amount authorized of $21.3 million equates to
919,178 shares using the closing market price of $23.13 on March 25, 1999.

        The Company has budgeted $58.0 million for capital expenditures in 1999,
which includes amounts for construction equipment, aggregate and asphalt plants,
buildings, leasehold improvements and the purchase of land and aggregate
reserves. The Company anticipates that cash generated internally and amounts
available under its existing credit facilities will be sufficient to meet its
capital and other requirements, including contributions to employee benefit
plans, for the foreseeable future. The Company currently has access to funds
under its revolving credit agreement which allow it to borrow up to $75.0
million, of which $71.5 million was available at December 31, 1998.

        SUBSEQUENT EVENTS. On March 17, 1999, the Board of Directors declared a
special dividend of $0.12 per share of common stock in addition to a $0.07 per
share quarterly dividend, payable on April 16, 1999 to stockholders of record as
of March 31, 1999. The quarterly dividend represents a $0.01 per share increase
over the dividends paid in the third and fourth quarter of 1998 of $0.06 per
share.

        IMPACT OF THE YEAR 2000 ISSUE. The Year 2000 issue is the result of
computer programs being written using two digits rather than four to define the
applicable year. The issue arises if date-sensitive software recognizes a date
using "00" as the year 1900 rather than the year 2000. This could result in a
system failure or miscalculations causing disruptions of operations, including,
among other things, a temporary inability to process transactions, send
invoices, or engage in similar normal business activities.

        The Company's information technology systems consist primarily of
hardware and software purchased from outside parties. The vendor for the
Company's enterprise-wide software has informed the Company that the version of
its software that the Company is currently utilizing is Year 2000 compliant and
the Company has substantially completed its testing to verify that this is the
case and will have its testing reviewed by a third party during the first half
of 1999. The Company is in the process of addressing the Year 2000 compliance of
other software and hardware, including embedded chips, being used in its
business. The Company is utilizing a seven step process in addressing compliance
of these other systems: (1) awareness; (2) inventory of all systems and
documentation; (3) assessment to identify any areas of noncompliance; (4)
remediation/renovation of any noncompliant systems; (5) verification of
compliance through testing and/or vendor certification; (6) implementation of
any necessary changes revealed during verifications; and (7) monitoring of the
results of implementation. The Company expects to have completed this process
for its non-enterprise software and hardware in mid 1999.

        The Company has begun the process of identifying and making inquiries of
its significant suppliers and large public and private sector customers to
determine the extent to which the Company is vulnerable to those third parties'
failure to solve their own Year 2000 issues. The Company expects that the
process of making inquiries to these significant suppliers and customers will be
ongoing through the end of 1999. However, there can be no guarantee that the
systems of other companies or public agencies with which the Company does
business will be timely converted, or that failure to convert by another company
or public agency would not have a material adverse effect on the Company.

        The Company's most reasonably likely worst case Year 2000 scenario would
be an interruption in work or cash flow resulting from unanticipated problems
encountered with the information systems of the Company, or of any of the
significant third parties with whom the Company does business. The Company
believes that the risk of significant business interruption due to unanticipated
problems with its own systems is low based on the progress of the Year 2000
project to date. If unforeseen internal disruptions occur, the Company believes
that its existing disaster recovery program, which includes the manual
processing of certain key transactions, would significantly mitigate the impact.
The Company's highest risk relates to significant suppliers or customers failing
to remediate their Year 2000 issues in a timely manner. Relating to its
suppliers, the Company has identified and will continue to identify alternative
suppliers. The Company's suppliers are generally locally or regionally based,
which tends to lessen the Company's exposure from the lack of readiness of any
single supplier. The risk relating to the Company's customers relates primarily
to any delay in receipt of payment due to a customer's unresolved Year 2000
issue. The Company's existing financial resources will help to mitigate such an
impact and the Company will continue to assess this risk as it receives
communications about the Year 2000 status of its customers.

        The Company estimates that costs to address the Year 2000 issue will
total approximately $500,000, including costs already incurred. These estimated
costs include consulting fees and costs to remediate or replace hardware and
software as well as non-incremental costs resulting from redeployment of
internal resources. To date, approximately $420,000 has been incurred and
expensed related to the Year 2000 issue. The Company's Year 2000 costs will be
funded from its operating cash flows. The Company does not expect its Year 2000
efforts to have any significant impact on other information technology projects.

ITEM 7A.    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

        The Company is exposed to financial market risks due primarily to
changes in interest rates which it manages primarily by managing the maturities
in its investment portfolio. The Company does not use derivatives to alter the
interest characteristics of its investment securities or its debt instruments.
The Company has no holdings of derivative or commodity instruments and does not
transact business in foreign currencies.

        The fair value of the Company's investment portfolio or related income
would not be significantly impacted by changes in interest rates since the
investment maturities are short and the interest rates are primarily fixed. The
Company's senior notes payable of $60.0 million at December 31, 1998 carry a
fixed interest rate of 6.54% per annum with principle payments due in nine equal
annual installments beginning in 2002. The Company's notes payable to bank of
$15.0 million carry a variable interest rate at primarily the IBOR rate plus
margin (5.91% at December 31, 1998) with principal payable semiannually through
June 2000.

        The table below presents principal amounts and related weighted average
interest rates by year for the Company's cash and cash equivalents, short-term
investments and significant debt obligations:

        The estimated fair value of the Company's cash, cash equivalents and
short-term investments approximate the principal amounts reflected above based
on the short maturities of these financial instruments. The estimated fair value
of the Company's debt obligations approximates the principal amounts reflected
above based on rates currently available for debt with similar terms and
remaining maturities.

                        REPORT OF INDEPENDENT ACCOUNTANTS



To the Stockholders and Board of Directors
Granite Construction Incorporated:
Watsonville, California


In our opinion, the accompanying consolidated balance sheets and the related
consolidated statements of income, stockholders' equity and of cash flows
present fairly, in all material respects, the financial position of Granite
Construction Incorporated and its subsidiaries at December 31, 1998 and 1997,
and the results of their operations and their cash flows for each of the three
years in the period ended December 31, 1998, in conformity with generally
accepted accounting principles. These financial statements are the
responsibility of the Company's management; our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these statements in accordance with generally accepted auditing
standards which require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for the opinion expressed above.

                        GRANITE CONSTRUCTION INCORPORATED
                 NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
                 (IN THOUSANDS, EXCEPT SHARE AND PER SHARE DATA)

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



1.         SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

                     DESCRIPTION OF BUSINESS: The Company is a heavy civil
           contractor engaged in the construction of highways, dams, airports,
           mass transit facilities, real estate site developments and other
           infrastructure related projects. The Company has offices in
           California, Texas, Georgia, Nevada, Arizona, Utah, Maryland and
           Florida.

                     PRINCIPLES OF CONSOLIDATION: The consolidated financial
           statements include the accounts of the Company and its wholly-owned
           subsidiaries. All significant intercompany transactions and accounts
           have been eliminated. The Company uses the equity method of
           accounting for companies where its ownership is between 20% and 50%
           and for other ventures and partnerships in which less than a
           controlling interest is held. The Company's proportionate share of
           construction joint venture revenue, cost of revenue and other income
           is included in the consolidated statements of income.

                     USE OF ESTIMATES IN THE PREPARATION OF FINANCIAL
           STATEMENTS: The preparation of financial statements in conformity
           with generally accepted accounting principles requires management to
           make estimates and assumptions that affect the reported amounts of
           assets and liabilities and disclosure of contingent assets and
           liabilities at the date of the financial statements and the reported
           amounts of revenues and expenses during the reporting period. Actual
           results could differ from those estimates.

                     CONSTRUCTION CONTRACTS: Earnings on construction contracts
           including construction joint ventures are recognized on the
           percentage of completion method in the ratio of costs incurred to
           estimated final costs. Revenue in an amount equal to cost incurred is
           recognized prior to contracts reaching 25% completion. The related
           earnings are not recognized until the period in which such percentage
           completion is attained. Revisions in contract revenue and cost
           estimates are reflected in the accounting period when known.
           Provision for the entire amount of estimated losses on uncompleted
           contracts is made in the period such losses are determined. Claims
           for additional contract revenue are recognized if it is probable that
           the claim will result in additional revenue and the amount can be
           reliably estimated.

                     BALANCE SHEET CLASSIFICATIONS: The Company includes in
           current assets and liabilities amounts receivable and payable under
           construction contracts which may extend beyond one year. A one-year
           time period is used as the basis for classifying all other current
           assets and liabilities.

                     CASH AND CASH EQUIVALENTS: Cash equivalents are securities
           held for cash management purposes having maturities of three months
           or less from the date of purchase.

                     SHORT-TERM INVESTMENTS: Short-term investments that are
           deemed by management to be held-to-maturity are reported at amortized
           cost. Short-term investments that are considered available-for-sale
           are carried at fair value. Unrealized gains and losses, if material,
           are reported net of tax as a separate component of stockholders'
           equity until realized. Realized gains and losses, if any, are
           determined using the specific identification method.

                     FINANCIAL INSTRUMENTS: The carrying value of short-term
           investments approximates their fair value as determined by market
           quotes. All significant debt obligations carry variable interest
           rates or interest rates that approximate market and their carrying
           value is considered to approximate fair value. The carrying value of
           receivables and other amounts arising out of normal contract
           activities, including retentions, which may be settled beyond one
           year, is estimated to approximate fair value.

                     INVENTORIES: Inventories consist primarily of quarry
           products valued at the lower of average cost or market.

1.         SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, CONTINUED

                     PROPERTY AND EQUIPMENT: Property and equipment are stated
           at cost. Depreciation is provided using accelerated methods over
           lives ranging from four to ten years for construction equipment and
           the straight-line method over lives from three to twenty years for
           the remaining depreciable assets. Depletion of quarry property is
           based on the usage of depletable reserves. The cost and accumulated
           depreciation or depletion of property sold or retired are removed
           from the accounts and gains or losses, if any, are reflected in
           earnings for the period.

                     INTANGIBLE ASSETS: Intangible assets consist primarily of
           covenants not to compete amortized on a straight-line basis over five
           years.

                     INCOME TAXES: Deferred taxes are provided on a liability
           method whereby deferred tax assets are recognized for deductible
           temporary differences and operating loss carryforwards and deferred
           tax liabilities are recognized for taxable temporary differences.
           Temporary differences are the differences between the reported
           amounts of assets and liabilities and their tax bases. Deferred tax
           assets are reduced by a valuation allowance when, in the opinion of
           management, it is more likely than not that some portion or all of
           the deferred tax assets will not be realized. Deferred tax assets and
           liabilities are adjusted for the effects of changes in tax laws and
           rates on the date of enactment.

                     COMPUTATION OF EARNINGS PER SHARE: Basic earnings per share
           is computed by dividing income available to common stockholders by
           the weighted average number of common shares outstanding, excluding
           restricted common stock. Diluted earnings per share is computed
           giving effect to all dilutive potential common shares that were
           outstanding during the period. Dilutive potential common shares
           consist of the incremental common shares issuable upon the exercise
           of stock options, warrants and upon the vesting of restricted common
           stock.

                     STOCK SPLIT: On July 6, 1998, the Company announced that
           its Board of Directors approved a three-for-two stock split in the
           form of a 50% stock dividend payable on August 7, 1998 to
           stockholders of record on July 17, 1998. All references in the
           financial statements to number of shares and per share amounts of the
           Company's common stock have been retroactively restated to reflect
           the increased number of shares outstanding.

                     RECLASSIFICATIONS: Certain financial statement items have
           been reclassified to conform to the current year's format. These
           reclassifications had no impact on previously reported net income.

                     COMPREHENSIVE INCOME: In the first quarter of 1998 the
           Company adopted Statement of Financial Accounting Standards No. 130,
           "Reporting Comprehensive Income," which specifies the computation,
           presentation and disclosure requirements for comprehensive income.
           There was no impact on the Company's financial position, results of
           operations or cash flows as a result of adoption. Comprehensive
           income and net income are the same.

2.         DISCLOSURE OF SIGNIFICANT RISKS AND UNCERTAINTIES

                     DISCLOSURE OF SIGNIFICANT ESTIMATES - REVENUE RECOGNITION:
           As outlined in the Summary of Significant Accounting Policies, the
           Company's construction revenue is recognized on the percentage of
           completion basis. Consequently, construction revenue and gross margin
           for each reporting period is determined on a contract by contract
           basis by reference to estimates by the Company's engineers of
           expected costs to be incurred to complete each project. These
           estimates include provisions for known and anticipated cost overruns,
           if any exist or are expected to occur. These estimates may be subject
           to revision in the normal course of business.

                     DISCLOSURE OF SIGNIFICANT ESTIMATES - LITIGATION: The
           Company has been named as a defendant in legal proceedings wherein
           substantial damages are claimed. Such proceedings are not uncommon in
           the Company's business and usually involve claims against multiple
           defendants who were involved in the project which is the subject of
           the proceeding. Historically, the Company has been successful in
           defending such actions or has settled them within insured limits.

                     CONCENTRATIONS: The Company maintains the majority of cash
           balances and all of its short-term investments with several financial
           institutions. The Company invests with high credit quality financial
           institutions, and, by policy, limits the amount of credit exposure to
           any financial institution. A significant portion of the Company's
           labor force is subject to collective bargaining agreements.
           Collective bargaining agreements covering 26.6% of the Company's
           unionized labor force at December 31, 1998 will expire during 1999.

                     Revenue received from federal, state and local government
           agencies amounted to $835,986 (68.2%) in 1998, $726,657 (70.6%) in
           1997, and $657,247 (70.7%) in 1996. California Department of
           Transportation represented $142,008 (11.6%) in 1998, $139,300 (13.5%)
           in 1997, and $104,171 (11.2%) in 1996 of total revenue. Utah
           Department of Transportation, including the Company's portion of a
           construction joint venture, represented $138,077 (11.3%) of total
           revenue in 1998. At December 31, 1998, 1997 and 1996 the Company had
           significant amounts receivable from these agencies. The Company
           performs ongoing credit evaluations of its customers and generally
           does not require collateral, although the law provides the Company
           the ability to file mechanics liens on real property improved for
           private customers in the event of non-payment by such customers. The
           Company maintains reserves for potential credit losses and such
           losses have been within management's expectations. The Company has no
           foreign operations.

           bear interest at 6.54% per annum. The Company used $39 million of the
           proceeds of the notes to retire its bank revolving credit notes.

                     Notes payable to bank are unsecured with principal payable
           semiannually and interest payable quarterly at primarily the IBOR
           rate plus margin (5.91% at December 31, 1998) through June 2000.

                     Restrictive covenants under the terms of debt agreements
           include the maintenance of certain levels of working capital and cash
           flow. Other covenants prohibit capital expenditures in excess of
           specified limits and require the maintenance of tangible net worth
           (as defined) of approximately $211,000.

                     Other notes payable are comprised primarily of notes
           incurred in connection with the purchase of property and equipment,
           and other assets. These notes are collateralized by the assets
           purchased and bear interest at 6.5% per annum with principal and
           interest payable in installments through 2007.

9.         EMPLOYEE BENEFIT PLANS

                     EMPLOYEE STOCK OWNERSHIP PLAN: The Company's Employee Stock
           Ownership Plan ("ESOP") covers all employees not included in
           collective bargaining agreements. As of December 31, 1998, the ESOP
           owned 7,641,422 shares of the Company's common stock. Dividends on
           shares held by the ESOP are charged to retained earnings and all
           shares held by the ESOP are treated as outstanding in computing the
           Company's earnings per share.

                     Contributions to the ESOP are at the discretion of the
           Board of Directors. Contributions for the years ended December 31,
           1998, 1997 and 1996 were approximately $1,957, $1,812 and $2,094,
           respectively.

                     PROFIT SHARING AND 401K PLAN: The Profit Sharing and 401k
           Plan is a defined contribution plan covering all employees not
           included in collective bargaining agreements. Each employee can elect
           to have up to 6% of gross pay contributed to the plan on a before-tax
           basis. The plan allows for Company matching and additional
           contributions at the discretion of the Board of Directors.

                     Contributions to the Profit Sharing and 401K Plan for the
           years ended December 31, 1998, 1997 and 1996 were $8,402, $4,706 and
           $4,064, respectively. Included in the contributions were 401K
           matching contributions of $1,990, $1,807 and 1,647, respectively.

                     OTHER: The Company`s wholly owned subsidiary, Granite
           Construction Company, also contributes to various multi-employer
           pension plans on behalf of union employees. Contributions to these
           plans for the years ended December 31, 1998, 1997 and 1996 were
           approximately $13,498, $11,972 and $10,406, respectively.

10.       STOCKHOLDERS' EQUITY

                     1990 OMNIBUS STOCK AND INCENTIVE PLAN: Under the Company's
          1990 Omnibus Stock and Incentive Plan (the "Stock Plan") a total of
          1,000,000 shares of the Company's common stock are reserved to grant
          key employees of the Company restricted common stock, incentive and
          nonqualified stock options, performance units and performance shares.
          Restricted common stock is issued for services to be rendered and may
          not be sold, transferred or pledged for such period as determined by
          the compensation committee.

          31, 1998 were 1,024,717 shares. Unearned compensation is amortized
          over the restriction periods of generally five years. Compensation
          expense related to restricted shares for the years ended December 31,
          1998, 1997 and 1996 was $3,286, $2,299 and $1,968, respectively.

          options granted under the Stock Plan may not be less than 100% and

          Options granted will be exercisable at such times and be subject to
          such restrictions and conditions as determined by the compensation
          committee, but no option shall be exercisable later than ten years
          from the date of grant. Options generally vest one third after 3 years
          of service from the date of grant and one third during each of the

14.       BUSINESS SEGMENT INFORMATION

                     The Company has two reportable segments: the Branch
          Division and the Heavy Construction Division (HCD). The Branch
          Division is comprised of branch offices that serve local markets,
          while HCD pursues major infrastructure projects throughout the nation.
          HCD generally has large heavy civil projects with contract amounts in
          excess of $15 million and contract durations greater than two years,
          while the Branch Division projects are typically smaller in size and
          shorter in duration. HCD has been the primary participant in the
          Company's construction joint ventures. Substantially all of the
          revenue from these joint ventures is included in HCD's revenues from
          external customers (Note 5).

                     The accounting policies of the segments are the same as
          those described in the summary of significant accounting policies
          (Note 1). The Company evaluates performance based on operating profit
          or loss which does not include income taxes, interest income, interest
          expense or other income (expense).

act or activity for which a corporation may be organized under the General
Corporation Law of Delaware.

        FOURTH:

               A.     Capitalization.  The total number of shares of all
classes of stock which the Corporation shall have authority to issue is
fifty-three million (53,000,000):

                      (1)  Three million (3,000,000) shares of Preferred Stock,
par value one cent ($0.01) per share (the "Preferred Stock"); and

                      (2)  Fifty million (50,000,000) shares of Common Stock,
par value one cent ($0.01) per share (the "Common Stock").

               B.     Series of Preferred Stock. The Board of Directors is
authorized, subject to any limitations prescribed by law, to provide for the
issuance of the shares of Preferred Stock in series, and by filing a certificate
pursuant to the applicable law of the State of Delaware, to establish from time
to time the number of shares to be included in each such series, and to fix the
designation, powers, preferences, and rights of the shares of each such series
and any qualifications, limitations or restrictions thereof.

        FIFTH:        The following provisions are inserted for the management
of the business and the conduct of the affairs of the Corporation, and for
further definition, limitation and regulation of the powers of the Corporation
and of its directors and stockholders:

               A.     Powers of Directors.  The business and affairs of the 
Corporation shall be managed by or under the direction of the Board of
Directors. In addition to the powers and

                                        1

<PAGE>   2
authority expressly conferred upon them by statute or by this Certificate of
Incorporation or the Bylaws of the Corporation, the directors are hereby
empowered to exercise all such powers and do all such acts and things as may be
exercised or done by the Corporation.

               B.     Ballot Unnecessary. The directors of the Corporation need
not be elected by written ballot unless the Bylaws so provide.

               C.     Stockholders Must Meet to Act. Any action required or
permitted to be taken by the stockholders of the Corporation must be effected at
a duly called annual or special meeting of stockholders of the Corporation and
may not be effected by any consent in writing by such stockholders.

               D.     Call of Special Meeting of Stockholders. Special meetings
of stockholders of the Corporation may be called only (1) by the Board of
Directors pursuant to a resolution adopted by a majority of the total number of
authorized directors (whether or not there exist any vacancies in previously
authorized directorships at the time any such resolution is presented to the
Board for adoption) or (2) by the holders of not less than ten percent (10%) of
all of the shares entitled to cast votes at the meeting. The procedure for
calling a special meeting of stockholders will be as set forth in this
Certificate of Incorporation or the Bylaws.

        SIXTH:

               A.     Classification of Directors. The directors shall be
divided into three classes, as nearly equal in number as reasonably possible,
with the term of office of the first class to expire at the 1991 annual meeting
of stockholders, the term of office of the second class to expire at the 1992
annual meeting of stockholders and the term of office of the third class to
expire at the 1993 annual meeting of stockholders. At each annual meeting of
stockholders following such initial classification and election, directors shall
be elected to succeed those directors whose terms expire for a term of office to
expire at the third succeeding annual meeting of stockholders after their
election. All directors shall hold office until the expiration of the term for
which elected, and until their respective successors are elected, except in the
case of the death, resignation, or removal of any director.

               B.     Filling Vacancies on the Board. Subject to the rights of
the holders of any series of Preferred Stock then outstanding, newly created
directorships resulting from any increase in the authorized number of directors
or any vacancies in the Board of Directors resulting from death, resignation,
retirement, removal from office, disqualification or other cause may be filled
only by a majority vote of the directors then in office, though less than a
quorum, and directors so chosen shall hold office for a term expiring at the
annual meeting of stockholders at which the term of office of the class to which
they have been elected expires.

               C.     Removal of Directors. Subject to the rights of the holders
of any series of Preferred Stock then outstanding, any directors, or the entire
Board of Directors, may be removed

                                        2

<PAGE>   3
from office at any time, but only for cause and only by the affirmative vote of
the holders of at least a majority of the voting power of all of the then
outstanding shares of capital stock of the Corporation entitled to vote
generally in the election of directors, voting together as a single class.

        SEVENTH:      Power to Amend Bylaws. The Board of Directors is expressly
empowered to adopt, amend or repeal Bylaws of the Corporation. Any adoption,
amendment or repeal of Bylaws of the Corporation by the Board of Directors shall
require the approval of a majority of the total number of authorized directors
(whether or not there exist any vacancies in previously authorized directorships
at the time any resolution providing for adoption, amendment or repeal is
presented to the Board). The stockholders shall also have power to adopt, amend
or repeal the Bylaws of the Corporation. In addition to any vote of the holders
of any class or series of stock of this Corporation required by law or by this
Certificate of Incorporation, the affirmative vote of the holders of at least
66-2/3 percent of the combined voting power of the outstanding shares of stock
of all classes and series of the Corporation entitled to vote generally in the
election of directors, voting together as a single class, shall be required to
adopt, amend or repeal any provision of the Bylaws of the Corporation.

        EIGHTH:       Vote Required for Certain Business Combinations. In 
addition to any affirmative vote required by law, any other provisions of this
Certificate of Incorporation or otherwise, none of the following transactions
shall be consummated unless and until such transaction shall have been approved
by the affirmative vote of the holders of at least 66-2/3 percent of the
combined voting power of the outstanding shares of stock of all classes and
series of the Corporation entitled to vote generally in the election of
directors:

                      (1)  any merger, reorganization or consolidation of or
share exchange made by the Corporation or any of its subsidiaries into or with
any other person, in each case irrespective of whether the Corporation or its
subsidiary is the surviving entity, provided, however, that the holders of a
majority of the combined voting power of the outstanding shares of all classes
and series of the Corporation entitled to vote generally in the election of
directors may approve any transaction, including a merger or consolidation, in
which the Corporation pays less than $20,000,000 in cash, assets or securities
(including securities of the Corporation) for the assets or securities of a
third party; or

                      (2) except in the ordinary course of business, any sale,
lease, exchange, mortgage, pledge, transfer or other disposition to or with any
other person (in a single transaction or a series of related transactions) of
all or a Substantial Part (as hereinafter defined) of the assets of the
Corporation (including without limitation any securities of a subsidiary); or

                      (3) except in the ordinary course of business, any sale,
lease, exchange, mortgage, pledge, transfer or other disposition to or with the
Corporation or to or with any of its subsidiaries (in a single transaction or
series of related transactions) of the assets or securities of any other person
if the fair market value of such assets or securities would constitute a

                                        3

<PAGE>   4
Substantial Part of the assets of the Corporation; or

                      (4) any agreement, contract or other arrangement providing
for any of the transactions described in this definition of Business
Combination. Anything in the foregoing to the contrary notwithstanding, the term
"Business Combination" shall not be deemed to include any of the transactions
contemplated by that certain Credit Agreement or that certain Business Loan
Agreement, both dated as of February 27, 1985, between the Corporation and Bank
of America N.T. & S.A., or any renewals, extensions or refundings thereof; or

                      (5) the adoption of any plan or proposal for the
liquidation or dissolution of the Corporation.

        The term "Substantial Part" shall mean more than 20% of the fair market
value of the total consolidated assets of the Corporation and its subsidiaries
taken as a whole, as determined by two-thirds of the members of the Board of
Directors of such person in good faith, as of the end of its most recent fiscal
year ending prior to the time the determination is being made.

        The terms "Business Combination" as used in this Article EIGHTH shall
mean any transaction or proposed transaction which is referred to in any one or
more of the foregoing subparagraphs (1) through (5) of this paragraph A of this

Board of Directors of the Corporation (the "Board"), when evaluating any offer
to another party (a) to make a tender or exchange offer for any capital stock of
the Corporation or (b) to effect any merger, consolidation, or sale of all or
substantially all of the assets of the Corporation, shall, in connection with
the exercise of its judgment in determining what is in the best interests of the
Corporation as a whole, be authorized to give due consideration to such factors
as the Board determines to be relevant, including, without limitation:

               (i)  the interests of the Corporation's stockholders;

               (ii) whether the proposed transaction might violate federal or
state laws;

               (iii) not only the consideration being offered in the proposed
transaction, in relation to the then current market price for the outstanding
capital stock of the Corporation, but also in relation to the market price for
the capital stock of the Corporation over a period of years, the estimated price
that will be achieved in a negotiated sale of the Corporation as a whole or in
part or through orderly liquidation, the premiums over market price for the
securities of other corporations in similar transactions, current political,
economic and other factors bearing on securities prices and the Corporation's
financial condition and future prospects; and

               (iv) the social, legal and economic effects upon employees,
suppliers, customers and others having similar relationships with the
Corporation, and the communities in which the

                                        4

<PAGE>   5


Corporation conducts its business.

        In connection with any such evaluation, the Board is authorized to
conduct such investigations and to engage in such legal proceedings as the Board
may determine.

        TENTH:        Elimination of Monetary Liability.  The liability of the
directors of the Corporation for monetary damages shall be eliminated to the
fullest extent permissible under Delaware law.

        Any repeal or modification of the foregoing provisions of this Article
TENTH by the stockholders of the Corporation shall not adversely affect any
right or protection of a director of the Corporation existing at the time of
such repeal or modification.

        ELEVENTH:     Future Amendments.  The Corporation reserves the right to
amend or repeal any provision contained in this Certificate of Incorporation in
the manner prescribed by the laws of the State of Delaware and all rights
conferred upon stockholders are granted subject to this reservation; provided,

the stock of this Corporation required by law or by this Certificate of
Incorporation, the affirmative vote of the holders of at least 66-2/3 percent of
the combined voting power of the outstanding shares of stock of all classes and
series of the Corporation entitled to vote generally in the election of
directors, voting together as a single class, shall be required to amend, repeal
or adopt any provision inconsistent with Article FIFTH (except Section D

                              GRANITE CONSTRUCTION

                          EMPLOYEE STOCK OWNERSHIP PLAN


                  As Amended and Restated as of January 1, 1998


Section 1.  Nature of the Plan.

            The purpose of this Plan is to enable participating Employees to
share in the growth and prosperity of Granite Construction Incorporated (the
"Company") and to provide Participants with an opportunity to accumulate capital
for their future economic security. The Plan is intended to do this without any
deductions from Participants' paychecks and without requiring them to invest
their personal savings. The primary purpose of the Plan is to enable
Participants to acquire stock ownership interests in the Company. Therefore, the
Trust established under the Plan is designed to invest primarily in Stock.

            The Plan is also designed to be available as a technique of
corporate finance to the Company. Accordingly, it may be used to accomplish the
following objectives:

        (a)     To meet general financing requirements of the Company, including
                capital growth and transfers in the ownership of Stock;

        (b)     To provide Participants with beneficial ownership of Stock,
                substantially in proportion to their relative Compensation,
                without requiring any cash outlay, any reduction in pay or other
                personal investment on the part of Participants; and

        (c)     To receive loans (or other extensions of credit) to finance the
                acquisition of Stock, with such loans to be repaid by Employer
                Contributions to the Trust and dividends received on such Stock.

            The Plan (originally adopted as the Granite Construction Company
Employee Stock Ownership Plan effective as of January 1, 1984, and subsequently
amended and restated 

<PAGE>   4

effective as of January 1, 1987, and April 20, 1990) is hereby amended and
restated as of January 1, 1998. The Plan is a stock bonus plan under Section
401(a) of the Internal Revenue Code of 1986, as amended (the "Code"), and an
employee stock ownership plan under Section 4975(e)(7) of the Code. To satisfy
applicable requirements of the Code, as amended by the Small Business Job
Protection Act of 1996, the fourth sentence of Section 3(c) is amended effective
as of December 12, 1994, and the definitions of "Compensation" and "Highly
Compensated Employee" in Section 2 and the second and third sentences of Section
12(c) are amended effective as of January 1, 1997.

            All Trust Assets held under the Plan will be administered,
distributed, forfeited and otherwise governed by the provisions of this Plan and
the related Trust Agreement. The Plan is administered by an Administrative
Committee for the exclusive benefit of Participants (and their Beneficiaries).

Section 2.  Definitions.

            In this Plan, whenever the context so indicates, the singular or
plural number and the masculine, feminine or neuter gender shall be deemed to
include the other, the terms "he," "his" and "him" shall refer to a Participant,

provided that he is still an Employee on such June 30th or December 31st. For
this purpose, the eligibility computation period for determining the 1,000 Hours
of Service requirement in the preceding sentence shall initially be the period
of 12 consecutive months beginning on the Employee's initial date of Service and
thereafter shall be the period of 12 consecutive months beginning on the
anniversary date of the Employee's initial date of Service.

            Employees whose terms of employment are covered by a collective
bargaining agreement shall not be eligible to participate in the Plan unless the
collective bargaining agreement specifically provides for such Employees to
participate in the Plan. Employees who are nonresident aliens who receive no
earned income from the Company or an Affiliate that constitutes income from
sources within the United States shall not be eligible to participate in the
Plan. An Employee who ceases to be ineligible to participate in the Plan shall
become a 



                                      -8-

Participant as of the later of the date he ceases to be ineligible or
the date described in the preceding paragraph.

            (b) A Participant is entitled to share in the allocation of Employer
Contributions and Forfeitures under Section 6(a) for each Plan Year in which he
is credited with at least 1000 Hours of Service and in which he is an Employee
on the Allocation Date. A Participant is also entitled to share in the
allocation of Employer Contributions and Forfeitures for the Plan Year of his
Retirement, Disability or death.

            (c) A former Participant who is reemployed by an Employer shall
become a Participant as of the date of his reemployment. A former Employee who
is reemployed by an Employer and who previously satisfied the service
requirement described in Section 3(a) shall become a Participant as of the later
of the date of his reemployment or the date described in Section 3(a).
Notwithstanding any provision of the Plan to the contrary, contributions,
benefits and service credit with respect to qualified military service will be
provided in accordance with Section 414(u) of the Code.

            (d) Hours of Service - For purposes of determining the Hours of
Service to be credited to an Employee under the Plan, the following rules shall
be applied:

                        (1)         Hours of Service shall include each hour of
                                    Service for which an Employee is paid (or
                                    entitled to payment) for the performance of
                                    duties; each hour of Service for which an
                                    Employee is paid (or entitled to payment)
                                    for a period during which no duties are
                                    performed (irrespective of whether Service
                                    has terminated) due to vacation, holiday,
                                    illness, incapacity (including Disability),
                                    layoff, jury duty, military duty or paid
                                    leave of absence; and each additional hour
                                    of Service for which back pay is either
                                    awarded or agreed to (irrespective of
                                    mitigation of damages); provided, however,
                                    that not more than 501 Hours of Service
                                    shall be credited for a single continuous
                                    period during which an Employee does 

                                      -9-
<PAGE>   12

                            not perform any duties (whether or not such
                            period occurs in a single Plan Year or 12 month
                            period, with respect to an Employee's initial
                            eligibility computation period).

                (2)         The crediting of Hours of Service shall be
                            determined in accordance with the rules set
                            forth in paragraphs (b) and (c) of Section
                            2530.200b-2 of the regulations prescribed by
                            the Department of Labor, which rules shall
                            be consistently applied with respect to all
                            Employees within the same job
                            classification.

                (3)         Hours of Service shall not be credited to an
                            Employee for a period during which no duties
                            are performed if payment is made or due
                            under a plan maintained solely for the
                            purpose of complying with applicable
                            worker's compensation, unemployment
                            compensation or disability insurance laws,
                            and Hours of Service shall not be credited
                            on account of any payment made or due an
                            Employee solely in reimbursement of medical
                            or medically-related expenses.

                (4)         Hours of Service that are credited for the
                            performance of duties shall be determined
                            from records maintained by the Employer;
                            provided, however, that, in the case of an
                            Employee whose Compensation is not
                            determined on the basis of certain amounts
                            for each hour worked and whose hours are not
                            required to be counted and recorded by any
                            Federal law (such as the Fair Labor
                            Standards Act), such Employee's Hours of
                            Service need not be determined from
                            employment records, and such Employee shall
                            be credited with ten Hours of Service for
                            each day in which he would be credited with
                            any Hours of Service. Hours of Service that
                            are credited for periods during which no
                            duties are performed or for back pay shall
                            be credited on the basis of 40 Hours of
                            Service for each week or eight Hours of
                            Service for each day.

Section 4.  Employer Contributions.

            (a) Employer Contributions shall be paid to the Trustee for each
Plan Year in such amounts (or under such formula) as may be determined by the
Board of Directors; provided, however, that the amount of Employer Contributions
must be at least sufficient to enable the Plan to make payments of principal
and/or interest on an outstanding Loan and that Employer 


                                      -10-
<PAGE>   13

Contributions shall not be made for any Plan Year in amounts which can be
allocated to no Participant's Accounts by reason of the allocation limitation
described in Section 7(a) or in amounts which are not deductible under Section
404(a) of the Code.

            (b) Employer Contributions for each Plan Year shall be paid to the
Trustee not later than the due date (including extensions) for filing the
Company's Federal income tax return for that Plan Year. Employer Contributions
may be paid in cash and/or in shares of Stock, as determined by the Board of
Directors; provided, however, that the Board of Directors may determine that
Employer Contributions may be paid as provided in Section 5(c) with notice to
the Committee and the Trustee. The amount of any Employer Contributions that are
paid in the form of shares of Stock shall be based upon Fair Market Value as of
the date such shares are issued to the Trust.

            (c) Any Employer Contributions which are not deductible under
Section 404(a) of the Code may be returned to the Employer by the Trustee (upon
the direction of the Company) within one year after the deduction is disallowed
or after it is determined that the deduction is not available. In the event that
Employer Contributions are paid to the Trust by reason of a mistake of fact,
such Employer Contributions may be returned to the Employer by the Trustee (upon
the direction of the Company) within one year after the payment to the Trust.

            (d) No Participant shall be required or permitted to make
contributions to the Trust.

Section 5.  Investment of Trust Assets.

            (a) In General - Trust Assets will be invested by the Trustee
primarily (or exclusively) in Stock in accordance with directions from the
Committee. Employer Contributions (and other Trust Assets) may be used to
acquire shares of Stock through open-market purchases, from any Company
shareholder in a privately-negotiated transaction or from the Company. The
Trustee may also invest Trust Assets in such other prudent investments as the
Committee deems to be desirable for the Trust, or Trust Assets may be held
temporarily in cash. All purchases of Stock by the Trustee shall be made only as
directed by the Committee and all purchases from a party in interest (as defined
in ERISA) shall be made only at prices which do not exceed Fair Market Value.
The Committee may direct the Trustee to invest and hold up to 100% of the Trust
Assets in Stock. 

            (b) Loans - With the approval of the Board of Directors, the
Committee may direct the Trustee to incur Loans from time to time to finance the
acquisition of Stock (Financed Shares) or to repay a prior Loan. An installment
obligation incurred in connection with the purchase of Stock shall be treated as
a Loan, and all indebtedness incurred in connection with a single acquisition of
Stock shall be treated as one Loan. A Loan shall be for a specific term, shall
bear a reasonable rate of interest and shall not be payable on demand except in
the event of default. A Loan may be secured by a pledge of the Financed Shares
so acquired (or acquired with the proceeds of a prior Loan which is being
refinanced). No other Trust Assets may be pledged as collateral for a Loan, and
no lender shall have recourse against Trust Assets except for Financed Shares
remaining pledged to the lender. Any pledge of Financed Shares must provide for
the release of the shares so pledged as payments on the Loan are made by the


                                      -12-
<PAGE>   15

Trustee and such Financed Shares are allocated to Participants' Stock Accounts
under Section 6(b). If the lender is a party in interest (as defined in ERISA),
any pledge of Financed Shares must provide for a transfer of Trust Assets to the
lender on default only upon and to the extent of the failure of the Trust to
meet the payment schedule of the Loan. 

        (c) Loan Payments - Payments of principal and/or interest on any Loan
shall be made by the Trustee (as directed by the Committee) only from Employer
Contributions paid in cash to enable the Trust to repay such Loan, from earnings
attributable to such Employer Contributions and from any cash dividends received
by the Trust on the Financed Shares (whether allocated or unallocated) purchased
with the proceeds of such Loan; and the payments made with respect to a Loan for
a Plan Year must not exceed the sum of such Employer Contributions, earnings and
dividends for that Plan Year (and prior Plan Years), less the amount of such
payments for prior Plan Years. If the Company is the lender with respect to a
Loan, Employer Contributions may be paid in the form of cancellation of
indebtedness under the Loan. If the Company is not the lender with respect to a
Loan, the Company may elect to make payments on the Loan directly to the lender
and to treat such payments as Employer Contributions. 

        (d) Sales of Stock - Subject to the approval of the Board of Directors
or except as otherwise provided in Section 8(b), the Committee may direct the
Trustee to sell shares of Stock to any person (including the Company), provided
that any such sale must be made at a price not less favorable to the Plan than
Fair Market Value as of the date of the sale and may be made only in compliance
with Federal and state securities laws. Notwithstanding the provisions of
Section 5(c), the Committee may direct the Trustee to apply the proceeds from
the sale of 


                                      -13-
<PAGE>   16

unallocated Financed Shares (in the Loan Suspense Account described in Section
6(b)) to repay the Loan (incurred to finance the purchase of such Financed
Shares) in the event of the merger, consolidation or sale of all or
substantially all of the assets of the Company or sale of all or substantially
all of the Stock of the Company or the termination of the Plan or if the Plan
ceases to be an employee stock ownership plan under Section 4975(e)(7) of the
Code. Any decision by the Committee to direct the Trustee to sell Stock under
this Section 5(d) must comply with the fiduciary duties applicable Section
404(a)(1) of ERISA and with the primary benefit rule of Section 408(b)(3)(A) of
EPISA and Section 4975(d)(3)(A) of the Code, if applicable.

Section 6.  Allocations to Participants' Accounts.

            A Stock Account and a Nonstock Account shall be maintained to
reflect the interest of each Participant under the Plan.

            Stock Account - The Stock Account maintained for each Participant
will be credited annually with his allocable share of Stock (including
fractional shares) purchased and paid for by the Trust or contributed in kind to
the Trust as an Employer Contribution, with any Forfeitures of Stock and with
any stock dividends on Stock allocated to his Stock Account.

            Nonstock Account - The Nonstock Account maintained for each
Participant will be credited annually with his allocable share of Employer
Contributions that are not in the form of Stock, with any Forfeitures from
Nonstock Accounts, with any cash dividends on Stock allocated to his Stock
Account (other than currently distributed dividends) and any net income (or
loss) of the Trust. Such Account will be debited for the Participant's share of
any cash 

                                      -14-
<PAGE>   17

payments made by the Trustee for the acquisition of Stock or for the
payment of any principal and/or interest on a Loan.

            The allocations to Participants' Accounts for each Plan Year will be
made as follows:

            (a) Employer Contributions and Forfeitures - Employer Contributions
under Section 4(a) and Forfeitures under Section 10(b) for each Plan Year shall
be allocated as of the Allocation Date among the Accounts of Participants so
entitled under Section 3(b) in the ratio that the Compensation of each such
Participant bears to the total Compensation of all such Participants, subject to
the allocation limitations described in Section 7.

            (b) Financed Shares - Any Financed Shares acquired by the Trust
shall initially be credited to a "Loan Suspense Account" and will be allocated
to the Stock Accounts of Participants only as payments on the Loan are made by
the Trustee. The number of Financed Shares to be released from the Loan Suspense
Account for allocation to Participants' Stock Accounts for each Plan Year shall
be determined by the Committee (as of each Allocation Date) as follows:

                        (1) Principal/Interest Method - The number of Financed 
Shares held in the Loan Suspense Account immediately before the release for the
current Plan Year shall be multiplied by a fraction. The numerator of the
fraction shall be the amount of principal and/or interest paid on the Loan for
that Plan Year. The denominator of the fraction shall be the sum of the
numerator plus the total payments of principal and interest on that Loan
projected to be paid for all future Plan Years. For this purpose, the interest
to be paid in future years is to be computed by using the interest rate in
effect as of the current Allocation Date.


                                      -15-
<PAGE>   18

                        (2) Principal Only Method - The Committee may elect (as 
to each Loan) or the provisions of the Loan may provide for the release of
Financed Shares from the Loan Suspense Account based solely on the ratio that
the payments of principal for each Plan Year bear to the total principal amount
of the Loan. This method may be used only to the extent that: (A) the Loan
provides for annual payments of principal and interest at a cumulative rate that
is not less rapid at any time than level annual payments of such amounts for ten
years; (B) interest included in any payment on the Loan is disregarded only to
the extent that it would be determined to be interest under standard loan
amortization tables; and (C) the entire duration of the Loan repayment period
does not exceed ten years, even in the event of a renewal, extension or
refinancing of the Loan.

            In each Plan Year in which Trust Assets are applied to make payments
on a Loan, the Financed Shares released from the Loan Suspense Account in
accordance with the provisions of this Section 6(b) shall be allocated among the
Stock Accounts of Participants in the manner determined by the Committee based
upon the source of funds (Employer Contributions, earnings attributable to such
Employer Contributions and cash dividends on Financed Shares allocated to
Participants' Stock Accounts or cash dividends on Financed Shares credited to
the Loan Suspense Account) used to make the payments on the Loan. If cash
dividends on Financed Shares allocated to a Participant's Stock Account are used
for payments on a Loan, Financed Shares (representing that portion of such
payments and whose Fair Market Value is at least equal to the amount of such
dividends) released from the Loan Suspense Account shall be allocated to that
Participant's Stock Account. 

                                      -16-
<PAGE>   19

        (c) Net Income (or Loss) of the Trust - The net income (or loss) of the
Trust for each Plan Year will be determined as of the Valuation Date. Prior to
the allocation of Employer Contributions and Forfeitures for the Plan Year, each
Participant's share of any net income (or loss) will be allocated to his
Nonstock Account in the ratio that the balance of his Nonstock Account on the
preceding Valuation Date (reduced by any distribution of Capital Accumulation
from such Account since the preceding Valuation Date) bears to the sum of such
Account balances for all Participants as of that date. The net income (or loss)
of the Trust includes the increase (or decrease) in the fair market value of
Trust Assets (other than Stock), interest income, dividends and other income and
gains (or losses) attributable to Trust Assets (other than any dividends on
allocated Stock) since the preceding Valuation Date, reduced by any expenses
charged to the Trust Assets since the preceding Valuation Date. The
determination of the net income (or loss) of the Trust shall not take into
account any interest paid by the Trust under a Loan.

        (d) Dividends on Stock - Any cash dividends received on shares of Stock
allocated to Participants' Stock Accounts will be allocated to the respective
Nonstock Accounts of such Participants. Any cash dividends received on
unallocated shares of Stock (including any Financed Shares credited to the Loan
Suspense Account) shall be included in the computation of the net income (or
loss) of the Trust. Any stock dividends received on Stock shall be credited to
the Accounts (including the Loan Suspense Account) to which such Stock was
allocated. Any cash dividends which are currently distributed to Participants
(or their Beneficiaries) under Section 13(a) shall not be credited to their
Nonstock Accounts.

                                      -17-
<PAGE>   20

        (e) Accounting for Allocations - The Committee shall establish
accounting procedures for the purpose of making the allocations to Participants'
Accounts provided for in this Section 6. The Committee shall maintain adequate
records of the aggregate cost basis of Stock allocated to each Participant's
Stock Account. The Committee shall also keep separate records of Financed Shares
acquired with the proceeds of each Loan and of Employer Contributions (and any
earnings thereon) made for the purpose of enabling the Trust to repay any Loan.
From time to time, the Committee may modify the accounting procedures for the
purposes of achieving equitable and nondiscriminatory allocations among the
Accounts of Participants in accordance with the general concepts of the Plan,
the provisions of this Section 6 and the requirements of the Code and ERISA.

Section 7.  Allocation Limitations.

            (a) Limitation on Annual Additions - The Annual Additions for each
Plan Year with respect to any Participant may not exceed the lesser of:

                        (1)         25% of his Statutory Compensation; or

                        (2)         $30,000, as may be adjusted for increases in
                                    the cost of living pursuant to Section
                                    4l5(d)(l)(C) of the Code.

For this purpose, "Annual Additions" shall be the total of the Employer
Contributions and Forfeitures (including any income attributable to Forfeitures)
allocated to the Accounts of a Participant for the Plan Year, excluding any
Employer Contributions which are used by the Trust (not later than the due date,
including extensions, for filing the Company's Federal income 


                                      -18-
<PAGE>   21

tax return for that Plan Year) to pay interest on a Loan and any Financed Shares
which are allocated as Forfeitures, plus any employer contributions (including
401(k) contributions) and forfeitures allocated to him under the Profit Sharing
Plan for the Plan Year. In determining such Annual Additions, Forfeitures of
Stock shall be included at the Fair Market Value as of the Allocation Date and
Employer Contributions in the form of Stock shall be included at the Fair Market
Value as of the date such shares are issued to the Trust.

            If the aggregate amount that would be allocated to the accounts of a
Participant under this Plan and the Profit Sharing Plan in the absence of this
limitation would exceed the amount set forth in this limitation, then, to the
extent necessary, the Participant's Annual Additions for the Plan Year shall be
reduced and reallocated to the Accounts of Participants not affected by this
limitation for the Plan Year in the following order: (1) any profit sharing
contributions under the Profit Sharing Plan made on the Participant's behalf for
the Plan Year shall be reduced, (2) any "additional 401(k) contributions" made
on a Participant's behalf for the Plan Year under the Profit Sharing Plan shall
be returned to the Participant as Compensation (together with any income
attributable thereto), (3) any 401(k) contributions (other than "additional
401(k) contributions") under the Profit Sharing Plan made on the Participant's
behalf for the Plan Year shall be returned to the Participant as Compensation
(together with any income attributable thereto), (4) any matching contributions
under the Profit Sharing Plan made on the Participant's behalf for the Plan Year
shall be reduced and (5) any Employer Contributions under this Plan made on the
Participant's behalf for the Plan Year shall be reduced.

                                      -19-
<PAGE>   22

            If, after such reductions, there are any Forfeitures which can be
allocated to no Participant's Accounts by reason of this limitation, such
Forfeitures shall be credited to a "Forfeiture Suspense Account" and allocated
as Forfeitures under Section 6(a) for the next succeeding Plan Year (prior to
the allocation of Employer Contributions for such succeeding Plan Year).

            (b) Limitations on Highly Compensated Employees - Not more than
one-third of the Employer Contributions for the Plan Year applied to pay
principal and/or interest on a Loan may be allocated to Participants who are
Highly Compensated Employees. The Committee shall reallocate Employer
Contributions to the extent necessary to satisfy this special rule. The Annual
Additions under Section 7(a) with respect to Financed Shares released from the
Loan Suspense Account (by reason of Employer Contributions used for payments on
a Loan) and allocated to Participants' Stock Accounts shall be based upon the
lesser of (A) the amount of such Employer Contributions (as determined after
application of the preceding sentence); or (B) the Fair Market Value of such
allocated Financed Shares as of the Allocation Date. Annual Additions shall not
include any allocation attributable to proceeds from the sale of Financed Shares
by the Trust or to appreciation (realized or unrealized) in the Fair Market
Value of Stock.

            (c) Limitation on Electing Shareholder - If a shareholder of Granite
Construction Company sold stock of Granite Construction Company to the Trust on
or before October 22, 1986, and elected nonrecognition of gain under Section
1042 of the Code, no portion of the stock purchased in any such transaction (or
any dividends or other income attributable thereto) may be allocated to the
Accounts of:

                 (1)         any Participant who has made an election 
                             under Section 1042 of the Code;

                 (2)         any Participant who is such selling
                             shareholder's spouse, brother or sister
                             (whether by the whole or half blood),
                             ancestor or lineal descendant (except as to
                             certain lineal descendants, to the extent
                             provided in Section 409(n)(3)(A) of the Code),
                             or any other person who bears a relationship to
                             such selling shareholder that is described in
                             Section 267(b) of the Code; or

                 (3)         any Participant owning (as determined under 
                             Section 318(a) of the Code)
                             more than 25% in value of such stock.

            To the extent that a Participant is subject to the allocation
limitation described in this Section 7(c) for a Plan Year, he shall not share in
the allocation of Employer Contributions and Forfeitures.

Section 8.  Voting or Tender of Stock.

            (a) Voting Stock - All shares of Stock held by the Trust shall be
voted by the Trustee only in accordance with the provisions of this Section
8(a). Each Participant (or Beneficiary) will be entitled to direct the Trustee
as to the manner in which shares of Stock then allocated to his Stock Account
will be voted. Each Participant (or Beneficiary) will also be entitled to
separately direct the Trustee as to the manner in which a portion of the shares
of Stock not then allocated to Participants' Stock Accounts will be voted. The
portion of the unallocated shares of Stock with respect to which a Participant
(or Beneficiary) may give voting instructions to the Trustee shall be the total
number of unallocated shares of Stock held by the Trust multiplied by a
fraction, the numerator of which is the number of shares of Stock then allocated
to his Stock Account and the denominator of which is the total number of shares
allocated to Participants' 

                                      -21-
<PAGE>   24

Stock Accounts. Each Participant (or Beneficiary) who is entitled to direct the
Trustee as to the manner in which shares of Stock will be voted shall be
provided with the proxy statement and other materials provided to Company
shareholders in connection with each shareholder meeting, together with a form
or forms upon which the Participant (or Beneficiary) shall have the right to
give confidential voting instructions to the Trustee separately for the
allocated and the unallocated shares. A Participant (or Beneficiary) who does
not give instructions to the Trustee shall be treated as having authorized the
Committee to direct the Trustee as to the voting of his shares.

            (b) Tender Offer - In the event that there should be a tender or
exchange offer for Stock, the response to such offer by the Trustee shall be
only in accordance with the provisions of this Section 8(b). Each Participant
(or Beneficiary) will be entitled to direct the Trustee as to the manner in
which to respond to such offer with respect to shares of Stock then allocated to
his Stock Account. Each Participant (or Beneficiary) will also be entitled to
separately direct the Trustee as to the manner in which to respond to such offer
with respect to a portion of the shares of Stock not then allocated to
Participants' Stock Accounts. The portion of the unallocated shares of Stock
with respect to which a Participant (or Beneficiary) may give instructions to
the Trustee shall be the total number of unallocated shares of Stock held by the
Trust multiplied by a fraction, the numerator of which is the number of shares
of Stock then allocated to his Stock Account and the denominator of which is the
total number of shares allocated to Participants' Stock Accounts. Each
Participant (or Beneficiary) who is entitled to direct the Trustee as to the
manner in which the Trustee will respond to any such offer shall be provided
with the tender offer materials and the Participant (or Beneficiary) shall have
the right 

                                      -22-
<PAGE>   25

to provide confidential instructions to the Trustee as to the manner
in which to respond to such offer with respect to the shares of Stock then
allocated to his Stock Account and separately with respect to a portion of the
shares of Stock not then allocated to Participants' Stock Accounts. A
Participant (or Beneficiary) who does not give instructions to the Trustee shall
be treated as having directed the Trustee not to tender.

            (c) Participant as Named Fiduciary - Each Participant (or
Beneficiary) shall be a named fiduciary of the Plan for the purpose of providing
directions as to the voting of the shares of Stock allocated to his Stock
Account and a portion of the shares of Stock not then allocated to Participants'
Stock Accounts pursuant to Section 8(a) and as to the tendering of such shares
of Stock pursuant to Section 8(b).

Section 9.  Disclosure to Participants.

            (a) Summary Plan Description - Each Participant shall be furnished
with the summary plan description of the Plan required by Sections 102(a)(l) and
104(b)(l) of ERISA. Such summary plan description shall be updated from time to
time as required under ERISA and Department of Labor regulations thereunder.

            (b) Summary Annual Report - Within two months after the due date for
filing the annual return/report (Form 5500) for the Plan with the Internal
Revenue Service, each Participant shall be furnished with the summary annual
report of the Plan required by Section 104(b)(3) of ERISA, in the form
prescribed in regulations of the U. S. Department of Labor.

                                      -23-
<PAGE>   26

            (c) Annual Statement - Following each Allocation Date, each
Participant shall be furnished with a statement reflecting the following
information:

                (1)         The balances (if any) in his Accounts as of 
                            the beginning of the Plan Year.

                (2)         The amount of Employer Contributions and
                            Forfeitures allocated to his Accounts for
                            that Plan Year.

                (3)         The adjustments to his Accounts to reflect
                            his share of dividends (if any) on Stock and
                            any net income (or loss) of the Trust for
                            that Plan Year.

                (4)         The new balances in his Accounts, including
                            the number of shares of Stock allocated to
                            his Stock Account and the Fair Market Value
                            as of that Allocation Date.

                (5)         His number of Years of Vesting Service and
                            his vested percentage in his Account
                            balances (under Sections 10 and 11) as of
                            that Allocation Date.

            (d) Additional Disclosure - The Company shall make available for
examination by any Participant copies of the Plan, the Trust Agreement and the
latest annual report of the Plan filed (on Form 5500) with the Internal Revenue
Service. Upon written request of any Participant, the Company shall furnish
copies of such documents and may make a reasonable charge to cover the cost of
furnishing such copies, as provided in regulations of the U. S. Department of
Labor.

Section 10.  Vesting and Forfeitures.

            (a) Vesting - A Participant's interest in his Accounts shall become
100% vested and nonforfeitable without regard to his Years of Vesting Service if
he (A) is eligible for Retirement 



                                      -24-
<PAGE>   27

(whether or not he actually terminates Service), (B) terminates Service by
reason of Disability, (C) dies while employed by the Company or an Affiliate, or
(0) completes five Years of Vesting Service.

            (b) Forfeitures - Any portion of the final balances in a
Participant's Accounts which is not vested (and does not become part of his
Capital Accumulation) will become a Forfeiture as of the Allocation Date of the
Plan Year in which he incurs a five-consecutive-year Break in Service (or in
which he dies, if earlier). Forfeitures shall first be charged against a
Participant's Nonstock Account, with any balance charged against his Stock
Account (at Fair Market Value). Financed Shares shall be forfeited only after
other shares of Stock have been forfeited. All Forfeitures will be reallocated
to the Accounts of remaining Participants, as provided in Section 6(a), as of
the Allocation Date of the Plan Year in which a five-consecutive-year Break in
Service occurs (or in which the Participant dies, if earlier).

Section 11.  Years of Vesting Service and Break in Service.

            (a) Years of Vesting Service - An Employee's Years of Vesting
Service shall be the number of Plan Years in which he is credited with at least
1000 Hours of Service. Years of Vesting Service shall include such Service with
the Company or any Affiliate.

            (b) Break in Service - A one-year Break in Service shall occur in a
Plan Year in which an Employee is not credited with more than 500 Hours of
Service as a result of his termination of Service. A five-consecutive-year Break
in Service shall be five consecutive one-year Breaks in Service.

                                      -25-
<PAGE>   28

            For purposes of determining whether a Break in Service has occurred,
if an Employee begins a maternity/paternity absence described in Section
411(a)(6)(E)(i) of the Code or a leave covered under the Family and Medical
Leave Act of 1993, the computation of his Hours of Service shall include the
Hours of Service that would have been credited if they had not been so absent
(or eight Hours of Service for each normal work day of such absence if the
actual Hours of Service cannot be determined). For purposes of this Section
11(b), a maternity/paternity absence means an absence from work (i) by reason of
the pregnancy of the Employee, (ii) by reason of the birth of a child of the
Employee, (iii) by reason of the placement of a child with the Employee in
connection with the adoption of such child by the Employee, or (iv) for purposes
of caring for such child for a period beginning immediately following such birth
or placement. An Employee shall be credited for such Hours of Service (up to a
maximum of 501 Hours of Service) in the Plan Year in which such absence begins
(if such crediting will prevent him from incurring a Break in Service in such
Plan Year) or in the next following Plan Year.

            In addition, if an Employee is eligible for and is granted leave
pursuant to the Company's family care leave plan, a Break in Service shall not
occur if the Employee returns to Service with an Employer, without any
intervening employment with another employer, immediately following the
expiration of such leave and remains employed for a period of 90 days
thereafter. The Employee shall be credited with the Hours of Service that would
have been credited if he had not been so absent (or eight Hours of Service for
each normal work day of such absence if the actual Hours of Service cannot be
determined) up to a maximum of 501 Hours of Service for each Plan Year during
the period of such absence (if such crediting will prevent him from incurring a
Break in Service for any such Plan Year).

<PAGE>   29

            (c) Reemployment - If a former Employee is reemployed after a
one-year Break in Service, the following special rules shall apply in
determining his Years of Vesting Service:

                        (1)         New Accounts may be established to reflect
                                    his interest in the Plan attributable to
                                    Service after the Break in Service.

                        (2)         If he is reemployed after the occurrence of
                                    a five-consecutive-year Break in Service,
                                    Years of Vesting Service after the Break in
                                    Service will not increase his vested
                                    interest in his Accounts attributable to
                                    Service prior to the Break in Service.

                        (3)         After he completes one Year of Vesting
                                    Service following reemployment, his Years of
                                    Vesting Service will include his Years of
                                    Vesting Service accumulated prior to the
                                    Break in Service.


Section 12.  When Capital Accumulation Will Be Distributed.

            (a) Except as otherwise provided in Sections 12(c) and 13, a
Participant's Capital Accumulation will be distributed following his termination
of Service, but only at the time and in the manner determined by the Committee.
If the value of a Participant's Capital Accumulation at the time distribution
would otherwise commence under this Section 12 exceeds $5,000, no portion of his
Capital Accumulation may be distributed to him before he attains age 65 without
his written consent.

            (b) In the event of a Participant's Retirement, Disability or death,
distribution of his Capital Accumulation shall occur during the Plan Year
following the Plan Year in which his Retirement, Disability or death occurs. If
a Participant's Service terminates for any other reason, distribution of his
Capital Accumulation shall occur during the Plan Year in which the third
anniversary of his termination of Service occurs (or, if earlier, during the
Plan Year following 

                                      -27-
<PAGE>   30

the Plan Year in which he would be eligible for Retirement (as a result of
attaining the requisite age and having previously completed the requisite number
of Years of Vesting Service), incurs a Disability or dies).

            (c) Distribution of a Participant's Capital Accumulation shall
commence not later than 60 days after the Allocation Date coinciding with or
next following the latest of (l) the date of his 65th birthday, (2) the l0th
anniversary of the date he became a Participant, or (3) the date he terminates
Service. The distribution of the Capital Accumulation of any Participant who
attains age 70 1/2 in a calendar year and either has (1) terminated Service or
(2) is a "5% owner" (as defined in Section 416(i)(l)(B)(i) of the Code) must
occur not later than April 1st of the next calendar year and must be made in
accordance with the regulations under Section 401(a)(9) of the Code, including
Section 1.40l(a)(9)-2. Distributions shall be offered to any other Participant
who attains age 70 1/2 before January 1, 1999, to the extent required under
Sections 401(a)(9) and 41l(d)(6) of the Code and the regulations issued
thereunder. If the amount of a Participant's Capital Accumulation cannot be
determined (by the Committee) by the date on which a distribution is to occur,
or if the Participant cannot be located, distribution of his Capital
Accumulation shall commence within 60 days after the date on which his Capital
Accumulation can be determined or after the date on which the Committee locates
the Participant.

            (d) If a Participant's Capital Accumulation is retained in the Trust
after his Service ends, his Accounts will continue to be treated as described in
Section 6. However, except as otherwise provided in Section 3(b), such Accounts
shall not be credited with any additional Employer Contributions and
Forfeitures. If the distribution of a Participant's Capital 


                                      -28-
<PAGE>   31

Accumulation does not occur during the Plan Year following the Plan Year in
which his Service terminates, his entire Capital Accumulation may be segregated
and invested in assets other than Stock (as determined by the Committee).

            (e) Notwithstanding any other provision of this Plan, all or a
portion of a Participant's Capital Accumulation may be distributed at any time
to the Participant's former spouse or other alternate payee, even prior to the
Participant's "earliest retirement age" (as defined in Section 414(p) of the
Code), if such distribution is made pursuant to and in accordance with the terms
of a "qualified domestic relations order" ("QDRO"), including QDROs which were
received prior to January 1, 1999. Such distribution will occur in a single lump
sum in the manner described in Section 14(a) as soon as practicable following
the date that the Committee determines that the order constitutes a QDRO. If the
value of a Participant's Capital Accumulation exceeds $5,000 (at the time a
distribution to the Participant's former spouse or other alternate payee would
otherwise be available under this Section 12(e)), no portion of such Capital
Accumulation may be distributed to his former spouse or other alternate payee,
without the written consent of such former spouse or other alternate payee.


Section 13.  In-Service Distributions.

            (a) Cash Dividends - If so determined by the Board of Directors, any
cash dividends payable on Stock allocated to the Stock Accounts of Participants
may be paid currently (or within 90 days after the end of the Plan Year in which
the dividends are paid to the Trust) in cash by the Trustee to such Participants
(or their Beneficiaries) on a nondiscriminatory basis, or the Company may pay
such dividends directly to the Participants (or Beneficiaries). Such


                                      -29-
<PAGE>   32

distribution (if any) of cash dividends may be limited to Participants who are
still Employees, may be limited to dividends on shares of Stock which are then
vested or may be applicable to cash dividends on all shares allocated to
Participants' Stock Accounts.

            (b) Withdrawals - A Participant who has attained age 55 and
completed at least ten Years of Participation in the Plan shall be notified of
his right to elect to (1) withdraw in cash a portion of the balance in his Stock
Account attributable to shares of Stock acquired by the Trust after December 31,
1986, or (2) have a portion of his Stock Account transferred to the Profit
Sharing Plan, as provided in Section 401(a)(28)(B) of the Code. An election to
make a withdrawal or transfer must be made on the prescribed form and filed with
the Committee within the 90-day period immediately following the Allocation Date
of a Plan Year in the Election Period. For purposes of this Section 13(b),
"Years of Participation" includes only those Plan Years in which the Participant
is eligible to receive an allocation of Employer Contributions and Forfeitures
pursuant to Section 3(b), and the "Election Period" means the period of six
consecutive Plan Years beginning with the Plan Year in which the Participant
first becomes eligible to make a withdrawal or transfer.

            For each of the first five Plan Years in the Election Period, the
Participant may elect to withdraw or transfer an amount which does not exceed
25% of the number of shares of Stock allocated to his Stock Account, less all
amounts previously withdrawn or transferred under this Section 13(b). In the
case of the sixth Plan Year in the Election Period, the Participant may elect to
withdraw or transfer an amount which does not exceed 50% of the number of shares
of Stock allocated to his Stock Account, less all amounts previously withdrawn
or transferred under this Section 13(b). No election shall be permitted if the
balance in a Participant's Stock 

                                      -30-
<PAGE>   33
Account as of the Allocation Date of the first Plan Year in the Election Period
has a Fair Market Value of $500 or less, unless and until the balance in his
Stock Account as of a subsequent Allocation Date in the Election Period exceeds
$500. Any withdrawal or transfer under this Section 13(b) shall be made within
90 days after the 90-day period in which the election may be made. A withdrawal
shall be treated as a distribution which is subject to the provisions of
Sections 14(c) and (e).

            (c) Hardship Withdrawals -

               (1) A Participant who is an Employee and who is not subject to 
the provisions of Section 16 of the Securities Exchange Act of 1934, as amended,
may request a hardship withdrawal of a portion of his Capital Accumulation if he
needs funds for the following reasons:

                     (i)         costs directly related to the purchase of a
                                 principal residence for the
                                 Participant (excluding mortgage payments);

                     (ii)        reimbursement of tuition and
                                 related educational fees,
                                 including room and board and the
                                 cost of textbooks, for
                                 post-secondary education of the
                                 Participant, his spouse, his
                                 children or his dependents (as
                                 defined in Section 152 of the
                                 Code); or

                     (iii)       payments necessary to prevent
                                 the eviction of the Participant
                                 from his principal residence or
                                 foreclosure on the mortgage on
                                 that residence.

            (2) A withdrawal of less than $1,000 will not be permitted, and no
more than two withdrawals will be permitted in each Plan Year. The determination
of the amount of funds needed by the Participant may include any amounts
necessary to pay any Federal, state or local income taxes or penalties
reasonably anticipated to result from the withdrawal. The maximum 


                                      -31-
<PAGE>   34

aggregate amount that may be withdrawn under this Section 13(c) is the lesser of
(l) 40% of the Participant's Capital Accumulation or (2) $200,000 (less any
amount withdrawn under the Profit Sharing Plan). A withdrawal shall be disbursed
proportionately from the Participant's Stock Account and Nonstock Account and,
within the Participant's Stock Account, proportionately from shares of Stock
acquired by the Trust prior to January 1, 1987, and shares of Stock acquired by
the Trust after December 31, 1986. Any withdrawal under this Section 13(c) shall
be requested and effected in accordance with such rules and procedures as may be
established from time to time by the Committee.

Section 14.  How Capital Accumulation Will Be Distributed.

            (a) The Trustee will make distributions from the Trust only as
directed by the Committee. Distribution of a Participant's Capital Accumulation
will be made in a single lump sum in whole shares of Stock, cash or a
combination of both, as determined by the Committee; provided, however, that
(except as provided in Section 13(b)), the Committee shall notify the
Participant of his right to demand distribution of his Capital Accumulation
entirely in whole shares of Stock (with only the value of any fractional share
paid in cash).

            (b) Distribution of a Participant's Capital Accumulation will be
made to the Participant if living, and if not, to his Beneficiary. In the event
of a Participant's death, his Beneficiary shall be his surviving spouse, or if
none, his estate. A Participant (with the written consent of his spouse, if any,
acknowledging the effect of the consent and witnessed by a notary public or Plan
representative) may designate a different Beneficiary (and contingent
Beneficiaries) from time to time by filing a written designation with the
Committee. A 


                                      -32-
<PAGE>   35

deceased Participant's entire Capital Accumulation shall be distributed to his
Beneficiary in a single lump sum as soon as practicable (but in no event later
than the December 3 1st of the calendar year that includes the fifth anniversary
of his death), whether or not such distribution has previously commenced.

            (c) The Company shall furnish the recipient of a distribution with
the tax consequences explanation required by Section 402(f) of the Code and
shall comply with the withholding requirements of Section 3405 of the Code and
of any applicable state law with respect to distributions from the Trust (other
than any dividend distributions under Section 13(a)). If the Committee so elects
for a Plan Year, distributions to Participants may commence less than 30 days
after the notice required under Section 1.411(a)-11(c) of the regulations under
the Code is given; provided, however, that no such distribution to a Participant
shall be made unless (1) the Participant is informed that he has the right for a
period of at least 30 days after receiving the notice to consider whether or not
to consent to a distribution (or a particular distribution option), and (2) the
Participant affirmatively elects to receive a distribution after receiving the
notice.
            (d) All shares of Stock distributed under the Plan will be readily
tradable on an established market; provided, however, that shares of Stock held
or distributed by the Plan may include such legend restrictions on
transferability as the Company may reasonably require in order to assure
compliance with applicable Federal and state securities laws. Except as
otherwise provided in this Section 14(d), no shares of Stock held or distributed
by the Trustee may be subject to a put, call or other option, or buy-sell or
similar arrangement. The provisions 



                                      -33-
<PAGE>   36

of this Section 14(d) shall continue to be applicable to Stock even if the Plan
ceases to be an employee stock ownership plan under Section 4975(e)(7) of the 
Code.

            (e) If a distribution of a Participant's Capital Accumulation is not
the minimum amount required to be distributed pursuant to the second and third
sentences of Section 12(c), the Committee shall notify the Participant (or any
spouse or former spouse who is his alternate payee under a "qualified domestic
relations order" (as defined in Section 414(p) of the Code)) of his right to
elect to have the "eligible rollover distribution" paid directly to an "eligible
retirement plan" (within the meaning of Section 401(a)(31) of the Code) that is
an individual retirement account described in Section 408(a) of the Code, an
individual retirement annuity described in Section 408(b) of the Code, a
qualified trust described in Section 401(a) of the Code or a qualified annuity
plan described in Section 403(a) of the Code that accepts "eligible rollover
distributions." If such an "eligible rollover distribution" is to be made to the
Participant's surviving spouse, the Committee shall notify the surviving spouse
of his right to elect to have the distribution paid directly to an "eligible
retirement plan" that is either an individual retirement account described in
Section 408(a) of the Code or an individual retirement annuity described in
Section 408(b) of the Code. Any election under this Section 14(e) shall be made
and effected in accordance with such rules and procedures as may be established
from time to time by the Committee in order to comply with Section 401(a)(31) of
the Code.

Section 15.  No Assignment of Benefits.

            A Participant's Capital Accumulation may not be anticipated,
assigned (either at law or in equity), alienated or subject to attachment,
garnishment, levy, execution or other legal or equitable process, except in
accordance with a "qualified domestic relations order" (as defined in Section
414(p) of the Code).

Section 16.  Administration.

            (a) Administrative Committee - The Plan will be administered by an
Administrative Committee composed of not fewer than three individuals appointed
by the Board of Directors to serve at its pleasure and without compensation. The
members of the Committee shall be the named fiduciaries with authority to
control and manage the operation and administration of the Plan. Members of the
Committee need not be Employees or Participants. Any Committee member may
resign by giving notice, in writing, to the Board of Directors.

            (b) Committee Action - Committee action will be by vote of a
majority of the members at a meeting or in writing by all the members without a
meeting. A Committee member who is a Participant shall not vote on any question
relating specifically to himself.

            The Committee shall choose from its members a Chairman and a
Secretary. The Chairman or the Secretary of the Committee shall be authorized to
execute any certificate or other written direction on behalf of the Committee.
The Secretary shall keep a record of the Committee's proceedings and of all
dates, records and documents pertaining to the administration of the Plan.

                              to be paid;

                  (4)         authorizing and directing all disbursements

                  (5)         establishing procedures in accordance with
                              Section 414(p) of the Code to determine the

                              orders and to administer distributions under
                              such qualified orders;

                  (6)         engaging any administrative, legal,
                              accounting, clerical or other services that
                              it may deem appropriate;

                  (7)         construing and interpreting the Plan and the
                              Trust Agreement and adopting rules for

                              documents and of ERISA and the Code;

                  (8)         compiling and maintaining all records it
                              determines to be necessary, appropriate or

                  (9)         reviewing the performance of the Trustee

                              duties, responsibilities and obligations
                              under the Plan and Trust Agreement; and

                  (10)        executing agreements and other documents on behalf

<PAGE>   39


            The Committee shall be responsible for directing the Trustee as to
the investment of Trust Assets. The Committee may delegate to the Trustee the
responsibility for investing Trust Assets other than Stock. The Committee shall
establish a funding policy and method for directing the Trustee to acquire Stock
(and for otherwise investing the Trust Assets) in a manner that is consistent
with the objectives of the Plan and the requirements of ERISA.

            The Committee shall perform its duties under the Plan and the Trust
Agreement solely in the interests of the Participants (and their Beneficiaries).
Any discretion granted to the Committee under any of the provisions of the Plan
or the Trust Agreement shall be exercised only in accordance with rules and
policies established by the Committee which shall be applicable on a
nondiscriminatory basis. The Committee shall have the full and exclusive
discretion to interpret and administer the Plan. All actions, interpretations
and decisions of the Committee are conclusive and binding on all persons, and
shall be given the maximum possible deference allowed by law.

            (d) Expenses - All reasonable expenses of administering the Plan and
Trust shall be charged to and paid out of the Trust Assets. The Company may,
however, pay all or any portion of such expenses directly, and payment of
expenses by the Company shall not be deemed to be Employer Contributions.

            (e) Information to be Submitted to the Committee - To enable the
Committee to perform its functions, the Company shall supply full and timely
information to the Committee on all matters as the Committee may require, and
shall maintain such other records as the Committee may determine are necessary
or appropriate in order to determine the benefits due or which may become due to
Participants (or Beneficiaries) under the Plan.

                                      -37-
<PAGE>   40

            (f) Delegation of Fiduciary Responsibility - The Committee from time
to time may allocate to one or more of its members and/or may delegate to any
other persons or organizations any of its rights, powers, duties and
responsibilities with respect to the operation and administration of the Plan
that are permitted to be so delegated under ERISA; provided, however, that
responsibility for investment of the Trust Assets may not be allocated or
delegated other than as provided in Section 16(c). Any such allocation or
delegation shall be made in writing, shall be reviewed periodically by the 
Committee and shall be terminable upon such notice as the Committee in its 
discretion deems reasonable and proper under the circumstances.

            (g) Bonding, Insurance and Indemnity - To the extent required under
Section 412 of ERISA, the Company shall secure fidelity bonding for the
fiduciaries of the Plan.

            The Company (in its discretion) or the Trustee (as directed by the
Committee) may obtain a policy or policies of insurance for the Committee (and
other fiduciaries of the Plan) to cover liability or loss occurring by reason of
the act or omission of a fiduciary. If such insurance is purchased with Trust
Assets, the policy must permit recourse by the insurer against the fiduciary in
the case of a breach of a fiduciary obligation by such fiduciary. The Company
hereby agrees, to the maximum extent permitted by law, to indemnify and hold
harmless the Committee and each of its designees under Section 16(f), who is an
officer, director or employee of any Employer, against any and all claims, loss,
damages, liability, expenses, including legal fees, costs, judgments, fines,
settlements and other amounts actually and reasonably incurred, including in
connection with any proceeding, arising by reason of the fact that such person
is or was acting in such capacity.

<PAGE>   41

            (h) Notices, Statements and Reports - The Company shall be the "Plan
Administrator" (as defined in Section 3(16)(A) of ERISA and Section 414(g) of
the Code) for purposes of the reporting and disclosure requirements of ERISA and
the Code. The Committee shall assist the Company, as requested, in complying
with such reporting and disclosure requirements. The Company shall be the
designated agent of the Plan for the service of legal process.

Section 17.  Claims Procedure.

            A Participant (or Beneficiary) who does not receive a distribution
of benefits to which he believes he is entitled may present a claim to the
Committee. The claim for benefits must be in writing and addressed to the
Committee or to the Company. If the claim for benefits is denied, the Committee
shall notify the Participant (or Beneficiary) in writing within 90 days after
the Committee initially received the benefit claim. If there are special
circumstances which require an extension of time for processing the claim for
benefits, the Committee's decision shall be rendered not later than 180 days
after receipt of a claim. Any notice of a denial of benefits shall advise the
Participant (or Beneficiary) of the basis for the denial, any additional
material or information necessary for the Participant (or Beneficiary) to
perfect his claim and the steps which the Participant (or Beneficiary)
must take to have his claim for benefits reviewed.

            Each Participant (or Beneficiary) whose claim for benefits has been
denied may file a written request for a review of his claim by the Committee.
The request for review must be filed by the Participant (or Beneficiary) within
60 days after he receives the written notice denying his claim. The decision of
the Committee will be made within 60 days after receipt of a 



                                      -39-
<PAGE>   42

request for review and shall be communicated in writing to the claimant. Such
written notice shall set forth the basis for the Committee's decision. If there
are special circumstances (such as the need to hold a hearing) which require an
extension of time for completing the review, the Committee's decision shall be
rendered not later than 120 days after receipt of a request for review. All
decisions and interpretations of the Committee under this Section 17 shall be
conclusive and binding upon all persons with an interest in the Plan and shall
be given the greatest deference permitted by law.

Section 18.  Limitation on Participants' Rights.

            A Participant's Capital Accumulation will be based solely upon his
vested interest in his Accounts and will be paid only from the Trust Assets. An
Employer, the Committee or the Trustee shall not have any duty or liability to
furnish the Trust with any funds, securities or other assets, except as
expressly provided in the Plan.

            The adoption and maintenance of the Plan shall not be deemed to
constitute a contract of employment or otherwise between an Employer and any
Employee, or to be a consideration for, or an inducement or condition of, any
employment. Nothing contained in this Plan shall be deemed to give an Employee
the right to be retained in the Service of an Employer or to interfere with the
right of an Employer to discharge, with or without cause, any Employee at any
time.

                                      -40-

Section 19.  Future of the Plan.

            The Company reserves the right to amend or terminate the Plan (in
whole or in part) and the Trust Agreement at any time, by action of the Board of
Directors. Neither amendment nor termination of the Plan shall retroactively
reduce the vested rights of Participants or permit any part of the Trust Assets
to be diverted to or used for any purpose other than for the exclusive benefit
of the Participants (and their Beneficiaries).

            The Company specifically reserves the right to amend the Plan and 
the Trust Agreement retroactively in order to satisfy any applicable 
requirements of the Code and ERISA.

            If the Plan is terminated (or partially terminated), participation
of Participants affected by the termination will end. If Employer Contributions
are not replaced by contributions to a comparable plan which satisfies the
requirements of Section 401(a) of the Code, the Accounts of only those
Participants who are Employees on the effective date of termination will become
nonforfeitable as of that date. A complete discontinuance of Employer
Contributions shall be deemed to be a termination of the Plan for this purpose.
The Capital Accumulation of those Participants whose Service terminated prior to
the effective date of Plan termination will continue to be determined pursuant
to Section 10(a); and, to the extent that such Participants are not vested, the
nonvested balances in their Accounts will become Forfeitures to be reallocated
as of the effective date of Plan termination (even if they have not incurred a
five-consecutive-year Break in Service).

            After termination of the Plan, the Trust will be maintained until
the Capital Accumulations of all Participants have been distributed. Capital
Accumulations may be 

                                      -41-
<PAGE>   44

distributed following termination of the Plan or
distributions may be deferred as provided in Section 12, as the Company shall
determine.

            In the event of the merger or consolidation of this Plan with
another plan, or the transfer of Trust Assets (or liabilities) to another plan,
the Account balances of each Participant immediately after such merger,
consolidation or transfer must be at least as great as immediately before such
merger, consolidation or transfer (as if the Plan had then terminated).

Section 20.  "Top-Heavy" Contingency Provisions.

            (a) The provisions of this Section 20 are included in the Plan
pursuant to Section 401(a)(10)(B)(ii) of the Code and shall become applicable
only if the Plan becomes a "top-heavy plan" under Section 416(g) of the Code for
any Plan Year.

            (b) The determination as to whether the Plan becomes "top-heavy" for
any Plan Year shall be made as of the Allocation Date of the immediately
preceding Plan Year by considering the Plan together with the Profit Sharing
Plan and any other tax-qualified plan maintained by an Affiliate in which a "key
employee" participates. The Plan and the Profit Sharing Plan (and any other plan
required to be aggregated with the Plan) shall be "top-heavy" only if the total
of the account balances under the Plan and the Profit Sharing Plan and such
other plan for "key employees" as of the determination date exceeds 60% of the
total of the account balances for all Participants. For such purpose, account
balances shall be computed and adjusted pursuant to Section 416(g) of the Code.
"Key employees" shall be certain Participants (who are officers or shareholders
of the Company) and Beneficiaries described in Section 416(i)(1) or (5) of the
Code.

                                      -42-
<PAGE>   45

            (c) For any Plan Year in which the Plan is "top-heavy," each
Participant who is an Employee on the Allocation Date (and who is not a "key
employee") shall receive a minimum allocation of Employer Contributions and
Forfeitures which is equal to the lesser of:

                        (1)         3% of his Statutory Compensation; or

                        (2)         the same percentage of his Statutory
                                    Compensation as the allocation to the "key
                                    employee" for whom the percentage is the
                                    highest for that Plan Year. 401(k)
                                    Contributions under the Profit Sharing Plan
                                    made by key employees during a Plan Year
                                    shall be included in determining the "key
                                    employee" with the highest percentage for
                                    such Plan Year.

For this purpose, Statutory Compensation of each Employee shall not take into
account any amount in excess of $160,000 (as adjusted periodically after 1998
for increases in the cost of living).

            (d) As of the first day of any Plan Year in which the Plan has
become "top-heavy," the applicable vesting schedule in Section 10(a)(2) shall be
amended (with respect to any Employee who is credited with at least one Hour of
Service after the Plan has become "top-heavy") to provide for vesting upon
completion of at least three Years of Vesting Service; provided, however, that
such vesting schedule described in this Section 20(d) is more favorable than the
applicable schedule described in Section 10(a)(2) with respect to such affected
Employee.

            If the Plan ceases to be "top-heavy," the Capital Accumulation of a
Participant who, at that time, has less than three years of Service shall
thereafter be determined under the applicable vesting schedule in Section
10(a)(2), instead of the vesting schedule in this Section 20(d), except that his
nonforfeitable percentage shall not be reduced below the nonforfeitable


                                      -43-
<PAGE>   46

percentage that he had at the time the Plan ceased to be "top-heavy." If the
Plan ceases to be "top-heavy," the Capital Accumulation of a Participant who, at
that time, has three or more years of Service shall continue to be determined
under the vesting schedule in this Section 20(d).

Section 21.  Governing Law.

            The provisions of this Plan and the Trust Agreement shall be
construed, administered and enforced in accordance with the laws of the State of
California, to the extent such laws are not superseded by ERISA.

Section 22.  Execution.

            To record this amendment and restatement of the Plan, the Company
has caused this document to be executed on this _____ day of________________ 199

                              GRANITE CONSTRUCTION

                         PROFIT SHARING AND 401(k) PLAN


                  Amendment No. 6 to Amended and Restated Plan


     WHEREAS, Granite Construction, Incorporated ("Granite") maintains the
Granite Construction Profit Sharing and 401(k) Plan (the "Plan") for the benefit
of the eligible employees of Granite and its subsidiaries;

     WHEREAS, it is desirable to amend the Plan to provide for the transfer of
certain "elective deferral accounts" from the Gibbons Company Profit Sharing and
Retirement Plan (the "Gibbons Plan") into the Plan, effective as of April 1,
1998; and

     WHEREAS, in connection with the termination of the Gibbons Plan, effective
as of March 31, 1998, it is desirable to amend the Plan to provide for the
transfer of the remaining portion of affected participants' benefits from the
Gibbons Plan into this Plan, in the event that such affected participants fail
to consent to distributions from the Gibbons Plan;

     NOW, THEREFORE, the Plan is hereby amended by adding Appendix A thereto,
effective as of April 1, 1998:

<PAGE>   2

                                   Appendix A
                          Frozen Gibbons Plan Accounts

     This Appendix A shall apply to "elective deferral accounts" transferred
from the Gibbons Company Profit Sharing and Retirement Plan (the "Gibbons Plan")
to the Plan on April 1, 1998, for the benefit of individuals who became
Employees upon the Company's acquisition of the Gibbons Company and its
affiliates ("Gibbons Employees"). This Appendix A shall also apply to the other
accounts of Gibbons Employees that are transferred from the Gibbons Plan to the
Plan because Gibbons Employees failed to consent to distributions of those
accounts upon the termination of the Gibbons Plan. Except as specifically noted
in this Appendix A, the Plan will be administered in accordance with the other
provisions of the Plan. 

     (a)  Transferred Accounts.

          (1)  Frozen Elective Deferral Account. The balance in a Gibbons
Employee's "elective deferral account" under the Gibbons Plan as of March 31,
1998, will be transferred to this Plan, effective as of April 1, 1998, and will
be maintained as his Frozen Elective Deferral Account. The interest of each
Gibbons Employee in his Frozen Elective Deferral Account shall be fully vested
at all times. 

          (2)  Frozen General Account. A Frozen General Account shall be
maintained for a Gibbons Employee in this Plan in the event that he fails to
consent to a distribution of his "rollover account", "employer matching
contribution account," "employer profit-sharing contribution account" and
"Davis-Bacon account" under the 


                                      -2-
<PAGE>   3

Gibbons Plan after its termination and within the 30-day period after being
informed that distributions are available. A Gibbons Employee's Frozen General
Account shall be credited initially with his balance in the Gibbons Plan prior
to the date of the transfer which is attributable to his "rollover account",
"employer matching contribution account," "employer profit-sharing contribution
account" and "Davis-Bacon account;" provided, however, that the after-tax
voluntary contributions made by a Gibbons Employee to the Gibbons Plan prior
January 1, 1987, and earnings thereon, shall be held in the Gibbons Employee's
Frozen Voluntary Account. The interest of each Gibbons Employee in his Frozen
General Account shall be fully vested at all times. 

          (3)  Frozen Voluntary Account. A Frozen Voluntary Account shall be
maintained for a Gibbons Employee in this Plan in the event that he fails to
consent to a distribution of his "voluntary account" from the Gibbons Plan after
its termination and within the 30-day period after being informed that
distributions are available. A Gibbons Employee's Frozen Voluntary Account shall
be credited initially with the balance in his (i) "voluntary account" under the
Gibbons Plan prior to the date of the transfer, and (ii) the subaccount of his
"employer profit-sharing contribution account" that held the after-tax voluntary
contributions that he made to the Gibbons Plan prior January 1, 1987, and
earnings thereon. The interest of each Gibbons Employee in his Frozen Voluntary
Account shall be fully vested at all times. 

     (b)  Distributions. All distributions from a Gibbons Employee's Frozen
Elective Deferral Account, Frozen General Account and Frozen Voluntary Account
(collectively referred to as "Frozen Accounts") shall be subject to the
provisions of 


                                      -3-
<PAGE>   4

Section 12, except as otherwise provided in this Appendix A. For purposes of
Section 12(c), distribution to a Gibbons Employee from his Frozen Accounts shall
commence no later than the date provided in the first sentence in Section 12,
unless a Gibbons Employee elects to maintain his Frozen Accounts in the Plan
until they are required to be distributed under the second and third sentences
of Section 12(c). For this purpose, failure to submit a claim for a distribution
shall be deemed such an election. A Gibbons Employee may elect to receive his
Frozen Accounts in one or a combination of the following forms:

               (i)  A single lump sum cash payment.

               (ii) Substantially equal monthly, quarterly or annual cash
                    installments over a period not exceeding the life expectancy
                    of the Gibbons Employee and the Gibbons Employee's spouse.
                    The minimum installment amount, regardless of the periodic
                    method chosen, must be at least $100.00.


If a Gibbons Employee fails to elect to a form of payment, payment shall be made
as a single lump sum cash payment. 

     (c)  In-Service Withdrawals. 

          (1)  Frozen General Account and Frozen Voluntary Account. Each Gibbons
Employee may request a withdrawal of all or a portion of his Frozen General
Account and Frozen Voluntary Account at any time in accordance with such rules
as may be prescribed by the Committee. A Gibbons Employee is entitled to make
only one 


                                      -4-

such withdrawal from such Frozen Accounts in any Plan Year. Such withdrawals
shall be distributed in the manner described in Appendix A(b).

          (2)  Frozen Elective Deferral Account. Each Gibbons Employee may
request a withdrawal of all or a portion of his Frozen Elective Deferral Account
at any time after he attains age 59 1/2 in accordance with such rules as may be
prescribed by the Committee. A Gibbons Employee is entitled to make only one
such withdrawal from his Frozen Elective Deferral Account in any Plan Year. Such
withdrawals shall be distributed in the manner described in Appendix A(b).

     To record the adoption of this Amendment No. 6 to the amended and restated
Plan, Granite has caused it to be executed this 30 day of March, 1998.

                     recent annual or quarterly financial statements of the
                     Company and its Subsidiaries.

              (b)    Section 1.01 of the Prior Credit Agreement shall be amended
by adding the following defined term in appropriate alphabetical order:

                            "Non-Guarantor Subsidiary" has the meaning specified

                     calendar quarter and the date on which the final payment of

                     Rate Loan exceeds 90 days or three months, respectively,
                     "Interest Payment Date" with respect to such Loans shall
                     include the date which falls 90 days or three months after
                     the beginning of such Interest Period, respectively.

              (d)    Section 1.01 of the Prior Credit Agreement shall be amended

                     "Revolving Termination Date" shall be deemed to refer to
                     any such Revolving Termination Date as extended from time
                     to time pursuant to, and subject to the conditions of,

       conditions of subsection 2.15(b)), and (ii) thereafter on the last
       Business Day of June and December of each year thereafter, through and

                        (j) Section 2.14 of the Prior Credit Agreement shall be
amended and restated in its entirety to read as follows:

                                    2.14  Guaranty of Obligations.  The
Obligations shall be jointly and severally guaranteed by the Guarantors pursuant
to one or more Guaranties. Promptly after the date that any Subsidiary or other
Person becomes a Material Subsidiary of the Company, and, in any event, within
ten Business Days following receipt by the Company from the Agent of a request
therefor, the Company will cause such Material Subsidiary to execute and deliver
to the Agent and the Banks a guaranty of the Obligations in substantially the
form of the Guaranty. In addition, promptly after any date that the total
revenues or total assets of all Subsidiaries which are not Guarantors (each, a
"Non-Guarantor Subsidiary") together exceed 20% of the total revenues or total
assets, as the case may be, of the Company and its Subsidiaries measured on a


                                       3
<PAGE>   4
       consolidated basis, and, in any event, within ten Business Days following
       receipt by the Company from the Agent of a request therefor, the Company
       will cause one or more Non-Guarantor Subsidiaries to execute and deliver
       to the Agent and the Banks a guaranty or guarantees of the Obligations in
       substantially the form of the Guaranty, such that after delivery of such
       guaranty or guarantees, the total revenues or total assets of all
       remaining Non-Guarantor Subsidiaries together are less than 20% of the
       total revenues or total assets, as the case may be, of the Company and
       its Subsidiaries measured on a consolidated basis. The Company shall in
       each case deliver or cause to be delivered such other items as may be
       reasonably requested by the Agent, at the request of any Bank, in
       connection with the foregoing, including resolutions, incumbency and
       officers certificates and opinions of counsel.

                        (k) Subsection 2.15(a) of the Prior Credit Agreement
shall be amended and restated in its entirety to read as follows:

                                         (a) Not earlier than April 30, 1999 and
not later than April 28, 2000, and, if the Revolving Termination Date has
previously been extended pursuant to this Section 2.15, not earlier than the
April 30 of the year immediately prior to the year in which the Revolving
Termination Date then occurs, and not later than the April 30 of the year in
which the Revolving Termination Date then occurs, the Company may, at its
option, request that all the Banks extend the Revolving Termination Date by one
year by means of a letter, addressed to the Agent and each Bank, substantially
in the form of Exhibit I; provided, however, that notwithstanding the foregoing,
the Revolving Termination Date shall occur on the date that the Commitments
terminate pursuant to Section 9.02 or the Revolving Commitments are terminated
pursuant to Section 2.05. The Revolving Termination Date shall be extended by
one year if all of the Banks consent (in each Bank's sole and absolute
discretion) to such extension, such consent to be given by executing and
delivering to the Agent, no later than 15 Business Days after its receipt of
such letter, a counterpart of such letter; provided, that, if, one or more Banks
decline to consent to the extension of the Revolving Termination Date, any
Bank's consent to such extension shall be nullified, and the Revolving
Termination Date shall not be extended. If any Bank fails to execute and deliver
such letter on or before the expiration of the aforesaid 15 Business Day period,
such Bank shall be deemed to have declined to consent to extend the Revolving
Termination Date, and the Revolving Termination Date shall not be extended.

                        (1) Subsection 7.03(i) of the Prior Credit Agreement
shall be amended and restated in its entirety to read as follows:

                                         (i)  within three Business Days after 
the date of such occurrence, if (A) any Person shall become a Subsidiary of the
Company, (B) any Subsidiary or other Person shall become a Material Subsidiary
of the Company, or (C) the total revenues or total assets of all Non-Guarantor
Subsidiaries shall at any time together exceed 20% of the total revenues or
total assets, as the case may be of the Company and its Subsidiaries measured on
a consolidated basis; and

                 3. Representations and Warranties. The Company hereby
represents and warrants to the Agent and the Banks as follows:

                        (a) Both before and after giving effect to this
Amendment, no Default or Event of Default has occurred and is continuing.

                        (b) The execution, delivery and performance by the
Company of this Amendment and by the Guarantors of their acknowledgment and
consent to this Amendment have been duly authorized by all necessary corporate,
partnership and other action and do not and will not require any registration
with, consent or approval of, notice to or action by, any Person (including any
Governmental Approvals) in order to be effective and enforceable. Each of the
Prior Credit Agreement as amended by this Amendment, the Guaranty and the other
Loan Documents to which the Company or any of its Subsidiaries is a party
constitutes and continues to constitute the legal, valid and binding obligations
of the Company and such Subsidiary party thereto, enforceable against the
Company and such Subsidiaries in accordance with their respective terms, without
defense, counterclaim or offset.

                        (c) All representations and warranties of the Company
contained in the Prior Credit Agreement are true and correct and will be true
and correct on the Effective Date.

                        (d) The Company is entering into this Amendment on the
basis of its own investigation and for its own reasons, without reliance upon
the Agent and the Banks or any other Person.

                 4. Effective Date. This Amendment will become effective the
date first above written (the "Effective Date"), provided that each of the
following conditions precedent is satisfied:

                        (a) The Agent has received in sufficient number for each
Bank, duly executed originals (or, if elected by the Agent, an executed
facsimile copy):

                                    (i)  of this Amendment, executed by the
                                         Company and each of the Banks; and

                                    (ii) of the Guarantors' Acknowledgment and
                                         Consent in the form attached hereto,
                                         executed by each Guarantor; and

                        (b) The Agent has received from the Company and each
Guarantor a copy of a resolution passed by the board of directors (or similar
governing body) of each such Person or its general partner, certified by the
Secretary or an Assistant Secretary of such corporation as being in full force
and effect on the date hereof, authorizing the execution, delivery and
performance of this Amendment or the Guarantors' Acknowledgment and Consent, as
applicable.

            5. Reservation of Rights. The Company acknowledges and agrees that
the execution and delivery by the Agent and the Banks of this Amendment shall
not be deemed to 



                                       5
<PAGE>   6
create a course of dealing or otherwise obligate the Agent or
the Banks to execute similar amendments under the same or similar circumstances
in the future.

          6.   Miscellaneous.

               (a)  Except as herein expressly amended, all terms, covenants and
provisions of the Prior Credit Agreement are and shall remain in full force and
effect and all references therein and in the other Loan Documents to such Credit
Agreement shall henceforth refer to the Prior Credit Agreement as amended by
this Amendment. This Amendment shall be deemed incorporated into, and a part of,
the Credit Agreement. This Amendment is one of the Loan Documents.

               (b)  This Amendment shall be binding upon and inure to the
benefit of the parties hereto and thereto and their respective successors and
assigns. No third party beneficiaries are intended in connection with this
Amendment.

               (c)  This Amendment shall be governed by and construed in
accordance with the law of the State of California.

               (d)  This Amendment may be executed in any number of
counterparts, each of which shall be deemed an original, but all such
counterparts together shall constitute but one and the same instrument. Each of
the parties hereto understands and agrees that this document (and any other
document required herein) may be delivered by any party thereto either in the
form of an executed original or an executed original sent by facsimile
transmission to be followed promptly by delivery of a hard copy original, and
that receipt by the Agent of a facsimile transmitted document purportedly
bearing the signature of a Bank or the Company or any Guarantor shall bind such
Bank, the Company, or such Guarantor, respectively, with the same force and
effect as the delivery of a hard copy original. Any failure by the Agent to
receive the hard copy executed original of such document shall not diminish the
binding effect of receipt of the facsimile transmitted executed original of such
document of the party whose hard copy page was not received by the Agent.

               (e)  This Amendment, together with the Credit Agreement, contains
the entire and exclusive agreement of the parties hereto with reference to the
matters discussed herein and therein. This Amendment supersedes all prior drafts
and communications with respect thereto. This Amendment may not be amended
except in accordance with the provisions of Section 11.01 of the Credit
Agreement.

               (f)  If any term or provision of this Amendment shall be deemed
prohibited by or invalid under any applicable law, such provision shall be
invalidated without affecting the remaining provisions of this Amendment or the
Prior Credit Agreement, respectively.

               (g)  Each of the provisions set forth in Article XI of the Prior
Credit Agreement is incorporated herein by this reference and made applicable to
this Amendment.

               (h)   The Company covenants to pay to or reimburse the Agent,
upon demand, for all costs and expenses (including allocated costs of in-house
counsel) incurred in connection with the development, preparation, negotiation,
execution and delivery of this Amendment.


          IN WITNESS WHEREOF, the parties hereto have executed and delivered
this Amendment as of the date first above written.

                              SEVENTH AMENDMENT TO
                       THE GIBBONS COMPANY PROFIT SHARING
                               AND RETIREMENT PLAN

                  This Seventh Amendment to the Gibbons Company Profit Sharing
and Retirement Plan (the "Plan") is made and entered into this 27th day of
February, 1998, by G.G.&R., Inc.
("GG&R"), the Sponsoring Employer of the Plan.

                                   WITNESSETH:

                  WHEREAS, GG&R has heretofore established the Plan (which Plan
has been amended and restated in its entirety effective for all Plan Years
commencing on or after January 1, 1989);

                  WHEREAS, GG&R has reserved the right to amend the Plan in
whole or in part;

                  WHEREAS, it is desirable to amend the Plan to transfer
participants' Elective Deferral Accounts to the Granite Construction Profit
Sharing and 401(k) Plan, effective as of April 1, 1998;

                  WHEREAS, GG&R previously amended the Plan to cease all
Employer Davis-Bacon Contributions (for any period beginning after May 31, 1995)
and all Elective Deferrals, Matching Contributions and rollover contributions
(for plan years beginning after December 31, 1995); and


<PAGE>   2

                  WHEREAS, GG&R desires to amend the Plan to terminate all
portions of the Plan (other than the portion attributable to participants'
Elective Deferral Accounts), effective as of March 31, 1998, and amend the Plan
to incorporate the applicable provisions of the Internal Revenue Code of 1986,
in effect as of the date of termination, as amended by the Small Business Job
Protection Act of 1996 and the Taxpayer Relief Act of 1997.

                  NOW, THEREFORE, in consideration of the foregoing premises,
GG&R amends the following Sections of the Plan (or portions thereof) as follows:

                  1. Section 2.07 is amended by deleting the last paragraph from
the definition of "Compensation" thereof effective as of January 1, 1997.

                  2. Section 2 is amended by deleting the definition of "Family
Member" in Section 2.23, effective as of January 1, 1997.

                  3. Section 2.27 is restated to read as follows, effective as 
of January 1, 1997:

                                    2.27 "HIGHLY COMPENSATED EMPLOYEE" shall
                  mean, for any Plan Year, an Employee, other than a
                  non-resident alien receiving no earned income from the
                  Employer from sources within the United States, who, during
                  such year or the preceding year (a) was at any time a Five
                  Percent Owner (as defined in Section 19.02(c)); or (b)
                  received Compensation from the Employer in excess of eighty
                  thousand dollars ($80,000) in the preceding Plan Year and was
                  in the group consisting of the top twenty percent (20%) of the
                  Employees when ranked on the basis of Compensation paid during
                  such Plan Year.

                                      -2-
<PAGE>   3

                  A former Employee who was a Highly Compensated Employee upon
                  separation from service or at any time after attaining age
                  fifty-five (55) shall be treated as a Highly Compensated
                  Employee.

                  For purposes of the above, Compensation is defined as in
                  Section 7.01(b) of this Plan, but shall include contributions
                  made by the Employer to a plan of deferred compensation
                  otherwise excluded in Section 7.01(b). The dollar amount in
                  (b) above shall be adjusted at the same time and in the same
                  manner as the benefit limitation for defined benefit plans
                  under Code Section 415(b)(l)(A).

                  For purposes of determining the number of Employees in the
                  top-paid group in (b) above, the following shall be excluded:
                  Employees who have not completed six (6) months of service;
                  Employees who normally work less than seventeen and one-half
                  (17-1/2) hours per week; Employees who normally work not more
                  than six (6) months per year; Employees who have not attained
                  age twenty-one (21); and Employees described in Section
                  2.22(a), except as provided in Regulations issued under Code
                  Section 414(q).

                  4. Section 2.33 is amended by restating the first sentence in
the first paragraph thereof effective as of January 1, 1997:

                  "LEASED EMPLOYEE" shall mean any person, who, pursuant to an
                  agreement between the Gibbons Employer and any other person or
                  organization (leasing organization), has performed services
                  for the Employer (or for the Gibbons Employer and related
                  persons) determined in accordance with Code Section 414(n)(6))
                  on a substantially full time basis for a period of at least
                  one (1) year and such services are performed under the primary
                  direction or control by the Gibbons Employer.

                  5. Section 2.41 is restated to read as follows, effective as
of January 1, 1997:

                                    2.41 "NON-HIGHLY COMPENSATED EMPLOYEE" shall
                  mean an Employee who is not a Highly Compensated Employee.

                  6. Section 3.04(e) is restated to read as follows, effective
as of August 5, 1993:

                  (e) For Plan Years beginning after December 31,
                      1984, in the case of an Employee who is
                      absent from work for any period:

                      (1)  By reason of the pregnancy of the Employee;

                      (2)  By reason of the birth of a child of the Employee;

                      (3)  By reason of the placement of a child with the 
                           Employee in connection with the adoption of such 
                           child by such Employee;

                      (4)  For purposes of caring for such child for a period 
                           beginning immediately following such birth or 
                           placement; or

                      (5)  By reason of any unpaid leave covered by the Family 
                           and Medical Leave Act of 1993 ("FMLA").

                      Hours of Service shall include the Hours of Service which
                      otherwise would normally have been credited to such
                      Employee but for such absence; or in any case in which the
                      Plan is unable to determine the Hours of Service to be
                      credited, eight (8) Hours of Service for each regularly
                      scheduled work day of such absence. The total number of
                      hours treated as Hours of Service under this Section by
                      reason of any pregnancy, placement or unpaid leave covered
                      by FMLA shall not exceed five hundred and one (501) hours
                      less the number of Hours of Service credited to an
                      Employee pursuant to Subsections (a) through (d) above,
                      for an absence described in this Subsection (e). The hours
                      described in this Subsection (e) shall be treated as Hours
                      of Service only in the computation period in which the
                      absence from work begins, if an Employee would be
                      prevented from incurring a One-Year Break in Service in
                      such computation period solely because the period of
                      absence is treated as Hours of Service as provided herein;
                      or in any other case, in the immediately following
                      computation period. Notwithstanding the foregoing, no
                      credit will be given pursuant to this Subsection (e)
                      unless the Employee furnishes to the Plan Administrator
                      such timely information as the Plan Administrator may
                      reasonably require to establish that the absence from work
                      is for reasons referred to herein, and the number of days
                      for which there was such an absence.

        7. Section 3.05(c) is amended by adding the following sentence at the
end thereof, effective as of December 12, 1994:

           Notwithstanding any provision of the Plan to the contrary,

        prior distribution, the benefit shall be paid as a single lump sum
        payment as soon as administratively feasible following the end of the

        distributed to the Participant (consistent with the Participant's
        election and the requirements of Section 9.03):

                (a) In the form of a cash lump sum payment; or

        13. Section 9.06(b) is amended by restating the second paragraph
thereof, effective as of January 1, 1997:

                  shall be provided within a reasonable period before the
                  Annuity Starting Date (or after such date, if so elected by
                  the Plan Administrator, provided, however, that such period
                  shall not end before the 30th day following the date on which
                  the notification was provided to a Participant). If the
                  Participant requests a specific written explanation of all or
                  any portion of the notification, the explanation shall be
                  provided within thirty (30) days of the Participant's request.
                  The Plan Administrator need not comply with more than one such

        14. Section 9.06(b) is further amended by restating the third paragraph
thereof, effective as of January 1, 1997:

                  During the Joint and Survivor Election Period, as hereinafter
                  defined, a Participant eligible to make the election to waive
                  the Automatic Qualified Joint and Survivor Annuity of
                  Subsection (a) shall be eligible to elect to receive his
                  benefits as provided in Section 9.03. The election shall be in
                  writing and may be revoked at any time during the Joint and
                  Survivor Election Period. New elections and revocations may be
                  made any number of times during the Joint and Survivor
                  Election Period after a previous election or revocation. For
                  purposes of this paragraph, the term "Joint and Survivor
                  Election Period" shall mean the ninety (90) day period ending
                  on the Annuity Starting Date (or ending after such date, if so
                  elected by the Plan Administrator, provided such period shall
                  not end before the 30th day following the date on which the
                  notification described in this Section 9.06(b) was provided to

                  Plan Year, payment to a Participant of that the portion of his
                  benefit which is

                attributable to his Annuity Eligible Accrued Benefit may
                commence less than 30 days after notification described in this
                Section 9.06(b) is given, provided that the following conditions
                are satisfied:

        (i)     The Plan Administrator clearly informs the Participant that he
                has the right to a period of at least 30 days after receiving
                the notification described in this Section 9.06(b) to consider
                the election to waive the Qualified Joint and Survivor Annuity
                form of payment;

                9.06(b); and

        (iv)    Payments are made after the end of the revocation period
                described in Subsection (iii) above.

        the second paragraph thereof to read as follows, effective as of

                  If the lump sum benefit otherwise payable to the Beneficiary
                  is not more than five thousand dollars ($5,000) and payment of
                  benefits to the deceased Participant has not previously
                  commenced, the benefit shall be paid as a single lump sum
                  payment.

                        spouse is less than five thousand dollars ($5,000), such
                        benefit shall be paid as a single lump sum payment.

                18. Section 11.02 is amended by restating the last sentence in
        the second paragraph thereof to read as follows, effective as of

                  However, if the lump sum amount that would be payable to a
                  Participant is not more than five thousand dollars ($5,000)
                  and the amount in the Participant's Account has never exceeded
                  that amount at the time of any prior distribution, then the
                  benefit shall be paid as a single lump sum payment, subject to
                  the limitations of this Section 11.02, as though the
                  Participant had elected immediate distribution.

                19. Section 16.05 is amended by adding the following sentence at
        the end of the first paragraph thereof effective as of April 1, 1998:

                  The Trustee will transfer the balance in a Participant's (or

                  contribution plan under Code Section 401(a), effective as of
                  April 1, 1998. Any optional forms of distribution or other
                  rights with respect to such assets which are required to be
                  preserved under Section 17.03 of the Plan and Code Section
                  411(d)(6) shall be provided under the 401(k) Plan.

                20. Section 17.01 is amended by adding the following sentence at
        the end thereof effective as of March 31, 1998:

                  The Plan is terminated effective as of March 31, 1998, with

                  Deferral Accounts will be transferred to the 401(k) Plan on
                  April 1, 1998, in the manner described in Section 16.05.

                        GRANITE CONSTRUCTION INCORPORATED

                    KEY MANAGEMENT DEFERRED COMPENSATION PLAN


     1.   Introduction. The Company hereby amends and restates the Plan,
effective as of January 1, 1998. The purpose of the Plan is to provide deferred
compensation to a select group of executive employees of the Company in
recognition of their contributions to the Company and its subsidiaries. This
document constitutes the written instrument under which the Plan is maintained.

     2.   Definitions.

          (a)  "Account" means as to any Participant the separate account
established and maintained by the Company in order to reflect his or her
interest in the Plan. Each Participant's Account will reflect the allocations
and earnings credited (or debited) thereto in accordance with Section 5.

          (b)  "Code" means the Internal Revenue Code of 1986, as amended.

          (c)  "Committee" means the Compensation Committee of the Company's
Board of Directors.

          (d)  "Company" means Granite Construction Incorporated, a Delaware
corporation, and any other affiliated entity that is designated from time to
time by the board of directors of Granite Construction Incorporated. As to a
particular Participant, "Company" refers to the corporate entity which is his or
her employer. For purposes of Sections 2(c), 5 and 10, "Company" refers only to
Granite Construction Incorporated.

          (e)  "Compensation" means "compensation" (as defined in the Company's
tax-qualified retirement plans) in excess of$150,000 (as indexed under section
401(a)(17) of the Code) but not in excess of $250,000 (as indexed from time to
time by the Committee).

          (f)  "ERISA" means the Employee Retirement Income Security Act of
1974, as amended.

          (g)  "Participant" means each employee of the Company who is
designated as such from time to time by the Committee.

          (h)  "Plan" means the Granite Construction Incorporated Key Management
Deferred Compensation Plan, as set forth in this instrument and as hereafter
amended.

          (i)  "Plan Year" means the calendar year.


<PAGE>   3

     3.   Eligibility To Participate. The Committee will, from time to time,
designate Company employees to be Participants. Each Participant selected by the
Committee must belong to a select group of management and highly compensated
employees of the Company.

     4.   Vesting. Each Participant will always be 100% vested in his or her
Account; provided, however, that if a Participant is terminated "for cause" (as
such term is defined in the Company's Ethics Policy Statement), the Participant
will forfeit all amounts other than his or her own Compensation deferrals.

     5.   Additions To Accounts.

          (a)  Participant Compensation Deferrals. Each Participant may annually
elect to defer the receipt of a whole percentage (up to 3% or such other
percentage as may be determined by the Company's board of directors) of his or
her Compensation.

          (b)  Dividend Switchback Deferrals. Under rules established by the
Committee, each Participant may elect to defer an additional portion of the
Participant's Compensation equal to the full amount of the quarterly cash
dividends that are paid to the Participant under Section 13(a) of the Granite
Construction Employee Stock Ownership Plan.

          (c)  Company Matching Contributions. The Company will annually credit
each Participant's Account with an amount equal to a percentage of the
Compensation deferred by the Participant under Section 5(a), which percentage
will equal the matching contribution percentage determined under the Granite
Construction Profit Sharing and 401(k) Plan for such Plan Year.

          (d)  Discretionary Contributions. Each Plan Year the Company will
credit each Participant's Account with an amount equal to a percentage of the
Participant's Compensation that is equal to the total discretionary contribution
percentage determined by the Company's board of directors with respect to such
year for the Granite Construction Profit Sharing and 401(k) Plan and the Granite
Construction Employee Stock Ownership Plan.

          (e)  Hypothetical Investment Experience. For each Plan Year, the
balance of each Participant's Account will be credited quarterly with
hypothetical earnings equal to one-quarter of the sum of the 30-day average of
the Lehman Brothers long term bond index (as published in the Wall Street
Journal) determined as of the December 1 of the prior Plan Year, plus 100 basis
points, or as determined by the Committee.

     6.   Deferral Elections. Each Participant must complete a deferral form for
each Plan Year with respect to which he or she wishes to defer the receipt of
Compensation. To be effective, each such deferral form must satisfy the
following rules:


                                      -2-
<PAGE>   4

          (a)  Content And Form Requirements. The deferral form must be signed
and dated by the Participant, and must specify the method for distribution of
the Participant's Account. A Participant's election to defer Compensation will
be irrevocable and cannot be modified or amended by the Participant.

          (b)  Timing Of Deferral Forms. In general, a Participant's deferral
form must be received by the Committee before the beginning of the Plan Year for
which the Compensation is payable. However, in the case of Compensation payable
with respect to the initial Plan Year, the deferral form must be received by the
Committee both (i) within 30 days of the later of the date that the Company
adopts the Plan or the date on which the employee is notified of his or her
eligibility to participate, and (ii) before the date on which the Compensation
subject to the deferral election would otherwise be paid.

     7.   Distribution Of Accounts.

          (a)  Form Of Distributions. Subject to Sections 7(b), 7(d), 7(g) and
10, each Participant will receive a distribution of the balance of his or her
Account in the form specified in the Participant's election form, which may be a
lump sum cash payment, or annual installments of substantially equal amounts
payable over a period of years certain not to exceed ten.

          (b)  Rules For Installment Distributions. If, at any time after
installment distributions have begun, the amount of any installment would be
less than $1,000, the remainder of the Participant's Account will he distributed
in a lump sum. The Committee may, in its sole discretion, accelerate the
installment distribution of any Account for any reason. Participant Accounts
will continue to be credited with hypothetical earnings under Section 5(e) while
they are in pay status.

          (c)  Timing Of Distributions. Subject to Sections 7(d), 7(g) and 10,
the distribution of the balance of a Participant's Account will be made or begin
as soon as practicable following the earliest of the following events:

          o    The Participant's disability, as determined under the Company's
               Long Term Disability Plan;

          o    The Participant's "retirement" under the Company's tax-qualified
               retirement plans; or

          o    The Participant's death.

          (d)  Special Rule for "For Cause" Terminations. If a Participant is
terminated "for cause" (as such term is defined in the Company's Ethics Policy
Statement), and the Participant forfeits all amounts other than his or her own
Compensation deferrals, then notwithstanding Sections 6, 7(a) or 7(c),
distribution of the vested portion of such Participant's 



                                      -3-
<PAGE>   5
\
Account will be made in a lump sum cash payment as soon as practicable following
his or her termination of Company employment.

          (e)  Timing Of Distribution To A Beneficiary. If a Participant dies
before receiving the distribution of his or her Account, the distribution of
such Account to his or her beneficiary will made as previously elected by the
Participant.

          (f)  Beneficiary Designation. Each Participant must designate a
beneficiary to receive a distribution of his or her Account if the Participant
dies before it is distributed to him or her. A beneficiary designation form must
be signed, dated and delivered to the Committee to become effective. In the
absence of a valid or effective beneficiary designation, the Participant's
surviving spouse will be his or her beneficiary or, if there is no surviving
spouse, the Participant's estate will be his or her beneficiary.

          (g)  Hardship Distributions. In the event of an unforeseeable
emergency, a Participant may apply to the Committee for a distribution of part
or all of his or her Account prior to the date that it would otherwise be
distributed under this Section 7. If the Committee approves such an application,
it will make such distribution as a lump sum cash payment.

     8.   Withholding. The Company will withhold from any Plan distribution all
required federal, state, local and other taxes and any other payroll deductions
required. Each Participant agrees as a condition of participation in the Plan to
have withheld annually from his or her salary such amounts as are necessary to
satisfy his or her FICA withholding requirements.

     9.   Administration. The Plan is administered and interpreted by the
Committee. The Committee has delegated to the Company's Vice President and
Director of Human Resources its responsibilities under the Plan. The Committee
(and its delegatee) have the full and exclusive discretion to interpret and
administer the Plan. All actions, interpretations and decisions of the Committee
(and its delegatee) are conclusive and binding on all persons, and will be given
the maximum possible deference allowed by law. The Company agrees to indemnify
and hold harmless the members of the Committee and any employee to whom the
Committee delegates any responsibility under the Plan.

     10.  Amendment Or Termination. The Company reserves the right, in its sole
and unlimited discretion, to amend or terminate the Plan at any time, without
prior notice to any Participant or beneficiary. Upon Plan termination, the
Account of each Participant will be distributed as a lump sum cash payment as
soon as practicable, without regard to Section 7 or the Participant's deferral
election.

     11.  Claims Procedure. Any person who believes that he or she is entitled
to any payment under the Plan may submit a claim in writing to the Committee. If
the claim is denied (either in full or in part), the claimant will be provided a
written notice explaining the specific reasons for the denial and referring to
the provisions of the Plan on which the denial is based. 


                                      -4-
<PAGE>   6

The notice will describe any additional information needed to support the claim.
The denial notice will be provided within 90 days after the claim is received.
If special circumstances require an extension of time (up to 90 days), written
notice of the extension will be given within the initial 90-day period.

     12.  Appeal Procedure. If a claimant's claim is denied, the claimant (or
his or her authorized representative) may apply in writing to the Committee for
a review of the decision denying the claim. The claimant (or representative)
then has the right to review pertinent documents and to submit issues and
comments in writing. The Committee will provide written notice of its decision
on review within 60 days after it receives a review request. If additional time
(up to 60 days) is needed to review the request, the claimant will be given
written notice of the reason for the delay.

     13.  Source Of Payments.

          (a)  No Plan Assets. Subject to Section 13(b), all payments under the
Plan will be paid in cash from the general funds of the Company, no separate
fund will be established under the Plan, and the Plan will have no assets. Any
right of any person to receive any payment under the Plan is no greater than the
right of any other unsecured creditor of the Company. The Plan constitutes a
mere promise by the Company to pay benefit payments in the future and is
unfunded for purposes of both Title I of ERISA and the Code.

          (b)  Rabbi Trust. The Company will (i) establish a trust, (ii) fund
such trust in the event that it determines that a "change in control" (as
defined in the trust agreement) is imminent, and (iii) arrange to have such
trust assume its obligations to pay benefits under the Plan. Any trust created
by the Company to assist it in meeting its obligations under the Plan will
conform to the terms of the model trust as described in Revenue Ruling 92-64.

     14.  Inalienability. A Participant's rights to benefits under the Plan are
not subject in any manner to anticipation, alienation, sale, transfer,
assignment, pledge, encumbrance, attachment, or garnishment by creditors of the
Participant or the Participant's beneficiary.

     15.  Applicable Law. The provisions of the Plan will be construed,
administered and enforced in accordance with ERISA and, to the extent
applicable, the laws of the State of California.

     16.  Severability. If any provision of the Plan is held invalid or
unenforceable, its invalidity or unenforceability will not affect any other
provision of the Plan, and the Plan will be construed and enforced as if such
provision had not been included.

     17.  No Employment Rights. Neither the adoption or maintenance of the Plan
will be deemed to constitute a contract of employment between the Company and
any employee, or to be a consideration for, or an inducement or condition of,
any employment. Nothing contained 


                                      -5-
<PAGE>   7

in this Plan will be deemed to give an employee the right to be retained in the
service of the Company or to interfere with the right of the Company to
discharge, with or without cause, any employee at any time.

     18.  Status Of Plan As ERISA "Top Hat" Plan. The Plan is intended to be an
unfunded plan maintained primarily for the purpose of providing deferred
compensation for a select group of management and highly compensated employees
and will be administered and construed to effectuate this intent. Accordingly,
the Plan is subject to Title I of ERISA, but is exempt from Parts 2, 3 and 4 of
such Title.

               KEY MANAGEMENT DEFERRED INCENTIVE COMPENSATION PLAN



<PAGE>   2
                        GRANITE CONSTRUCTION INCORPORATED

               KEY MANAGEMENT DEFERRED INCENTIVE COMPENSATION PLAN


            1. Introduction. The Company hereby amends and restates the Plan,
effective as of January 1, 1998. The purpose of the Plan is to provide deferred
compensation to a select group of executive employees of the Company in
recognition of their contributions to the Company and its subsidiaries. This
document constitutes the written instrument under which the Plan is maintained.

            2. Definitions.

               (a) "Account" means as to any Participant the separate account
established and maintained by the Company in order to reflect his or her
interest in the Plan. Each Participant's Account will reflect the allocations
and earnings credited (or debited) thereto in accordance with Section 5.

               (b) "Code" means the Internal Revenue Code of 1986, as amended.

               (c) "Committee" means the Compensation Committee of the Company's
Board of Directors.

               (d) "Company" means Granite Construction Incorporated, a Delaware
corporation, and any other affiliated entity that is designated from time to
time by the board of directors of Granite Construction Incorporated. As to a
particular Participant, "Company" refers to the corporate entity which is his or
her employer. For purposes of Sections 2(c) and 10, "Company" refers only to
Granite Construction Incorporated.

               (e) "Compensation" means the annual cash incentive compensation
payable to a Participant.

               (f) "ERISA" means the Employee Retirement Income Security Act of
1974, as amended.

               (g) "Participant" means each employee of the Company who is
designated as such from time to time by the Committee.

               (h) "Plan" means the Granite Construction Incorporated Key
Management Deferred Incentive Compensation Plan, as set forth in this instrument
and as hereafter amended.

               (i) "Plan Year" means the calendar year.

<PAGE>   3
               
               3. Eligibility To Participate. The Committee will, from time to
time, designate Company employees to be Participants. Each Participant selected
by the Committee must belong to a select group of management and highly
compensated employees of the Company.

               4. Vesting. Each Participant will always be 100% vested in his or
her Account; provided, however, that if a Participant is terminated "for cause"
(as such term is defined in the Company's Ethics Policy Statement), the
Participant will forfeit all amounts other than his or her own Compensation
deferrals.

               5. Additions To Accounts.

               (a) Participant Compensation Deferrals. Each Participant may
annually elect to defer the receipt of up to and including 100% of his or her
Compensation.

               (b) Hypothetical Investment Experience. For each Plan Year, the
balance of each Participant's Account will be credited quarterly with
hypothetical earnings equal to one-quarter of the sum of the 30-day average of
the Lehman Brothers long term bond index (as published in the Wall Street
Journal) determined as of the December 1 of the prior Plan Year, plus 100 basis
points, or as determined by the Committee.

          6. Deferral Elections. Each Participant must complete a deferral form
for each Plan Year with respect to which he or she wishes to defer the receipt
of Compensation. To be effective, each such deferral form must satisfy the
following rules:

               (a) Content And Form Requirements. The deferral form must be
signed and dated by the Participant, and must specify the payment date and
method for distribution of the Participant's Account. Each annual deferral must
be for a minimum amount of at least $1,000, and must be for a period of at least
five years. A Participant may extend (but not reduce) the length of his or her
deferral period for one-year periods, so long as such extensions are made at
least 12 months prior to an otherwise scheduled distribution date. A
Participant's election to defer Compensation will be irrevocable and cannot be
modified or amended by the Participant.

               (b) Timing Of Deferral Forms. In general, a Participant's
deferral form must be received by the Committee before the beginning of the Plan
Year in which the Compensation is payable. However, in the case of Compensation
payable with respect to the initial Plan Year, the deferral form must be
received by the Committee both (i) within 30 days of the later of the date that
the Company adopts the Plan or the date on which the employee is notified of his
or her eligibility to participate, and (ii) before the date on which the
Compensation subject to the deferral election would otherwise be paid.


                                      -2-
<PAGE>   4

          7. Distribution Of Accounts.

               (a) Form Of Distributions. Subject to Sections 7(b), 7(d), 7(g)
and 10, each Participant will receive a distribution of the balance of his or
her Account in the form specified in the Participant's election form, which may
be a lump sum cash payment, or annual installments of substantially equal
amounts payable over a period of years certain not to exceed ten years.

               (b) Rules For Installment Distributions. If, at any time after
installment distributions have begun, the amount of any installment would be
less than $1,000, the remainder of the Participant's Account will be distributed
in a lump sum. The Committee may, in its sole discretion, accelerate the
installment distribution of any Account for any reason. Participant Accounts
will continue to be credited with hypothetical earnings under Section 5(b) while
they are in pay status.

               (c) Timing Of Distributions. Subject to Sections 7(d), 7(f) and
10, the distribution of the balance of a Participant's Account will be made or
begin as soon as practicable following the earliest of the following events:

               -    Occurrence of the date set forth in the Participant's
                    deferral form;

               -    The Participant's disability, as determined under the
                    Company's Long Term Disability Plan;

               -    The Participant's "retirement" under the Company's
                    tax-qualified retirement plans; or

               -    The Participant's death.

               (d) Special Rule for "For Cause" Terminations. If a Participant
is terminated "for cause" (as such term is defined in the Company's Ethics
Policy Statement), and the Participant forfeits all amounts other than his or
her own Compensation deferrals, then notwithstanding Sections 6, 7(a) or 7(c),
distribution of the vested portion of such Participant's Account will be made as
a lump sum cash payment as soon as practicable following his or her termination
of Company employment.

               (e) Timing Of Distribution To A Beneficiary. If a Participant
dies before receiving the distribution of his or her Account, the distribution
of such Account to his or her beneficiary will made as previously elected by the
Participant.

               (f) Beneficiary Designation. Each Participant must designate a
beneficiary to receive a distribution of his or her Account if the Participant
dies before it is distributed to him or her. A beneficiary designation form must
be signed, dated and delivered to the 



                                      -3-
<PAGE>   5

Committee to become effective. In the absence of a valid or effective
beneficiary designation, the Participant's surviving spouse will be his or her
beneficiary or, if there is no surviving spouse, the Participant's estate will
be his or her beneficiary.

               (g) Hardship Distributions. In the event of an unforeseeable
emergency, a Participant may apply to the Committee for a distribution of part
or all of his or her Account prior to the date that it would otherwise be
distributed under this Section 7. If the Committee approves such an application,
it will make such distribution as a lump sum cash payment.

            8. Withholding. The Company will withhold from any Plan distribution
all required federal, state, local and other taxes and any other payroll
deductions required. Each Participant agrees as a condition of participation in
the Plan to have withheld annually from his or her salary such amounts as are
necessary to satisfy his or her FICA withholding requirements.

            9. Administration. The Plan is administered and interpreted by the
Committee. The Committee has delegated to the Company's Vice President and
Director of Human Resources its delegable responsibilities under the Plan. The
Committee (and its delegatee) have the full and exclusive discretion to
interpret and administer the Plan. All actions, interpretations and decisions of
the Committee (and its delegatee) are conclusive and binding on all persons, and
will be given the maximum possible deference allowed by law. The Company agrees
to indemnify and hold harmless the members of the Committee and any employee to
whom the Committee delegates any responsibility under the Plan.

            10. Amendment Or Termination. The Company reserves the right, in its
sole and unlimited discretion, to amend or terminate the Plan at any time,
without prior notice to any Participant or beneficiary. Upon Plan termination,
the Account of each Participant will be distributed as a lump sum cash payment
as soon as practicable, without regard to Section 7 or the Participant's
deferral election.

            11. Claims Procedure. Any person who believes that he or she is
entitled to any payment under the Plan may submit a claim in writing to the
Committee. If the claim is denied (either in full or in part), the claimant will
be provided a written notice explaining the specific reasons for the denial and
referring to the provisions of the Plan on which the denial is based. The notice
will describe any additional information needed to support the claim. The denial
notice will be provided within 90 days after the claim is received. If special
circumstances require an extension of time (up to 90 days), written notice of
the extension will be given within the initial 90-day period.

            12. Appeal Procedure. If a claimant's claim is denied, the claimant
(or his or her authorized representative) may apply in writing to the Committee
for a review of the decision denying the claim. The claimant (or representative)
then has the right to review pertinent documents and to submit issues and
comments in writing. The Committee will provide written notice of its decision
on review within 60 days after it receives a review request. If additional 

                                      -4-
<PAGE>   6

time (up to 60 days) is needed to review the request, the claimant will be given
written notice of the reason for the delay.

            13. Source Of Payments.

               (a) No Plan Assets. All payments under the Plan will be paid in
cash from the general funds of the Company, no separate fund will be established
under the Plan, and the Plan will have no assets. Any right of any person to
receive any payment under the Plan is no greater than the right of any other
unsecured creditor of the Company. The Plan constitutes a mere promise by the
Company to pay benefit payments in the future and is unfunded for purposes of
both Title I of ERISA and the Code.

               (b) Rabbi Trust. The Company will (i) establish a trust, (ii)
fund such trust in the event that it determines that a "change in control" (as
defined in the trust agreement) is imminent, and (iii) arrange to have such
trust assume its obligations to pay benefits under the Plan. Any trust created
by the Company to assist it in meeting its obligations under the Plan will
conform to the terms of the model trust as described in Revenue Ruling 92-64.

            14. Inalienability. A Participant's rights to benefits under the
Plan are not subject in any manner to anticipation, alienation, sale, transfer,
assignment, pledge, encumbrance, attachment, or garnishment by creditors of the
Participant or the Participant's beneficiary.

            15. Applicable Law. The provisions of the Plan will be construed,
administered and enforced in accordance with ERISA and, to the extent
applicable, the laws of the State of California.

            16. Severability. If any provision of the Plan is held invalid or
unenforceable, its invalidity or unenforceability will not affect any other
provision of the Plan, and the Plan will be construed and enforced as if such
provision had not been included.

            17. No Employment Rights. Neither the adoption or maintenance of the
Plan will be deemed to constitute a contract of employment between the Company
and any employee, or to be a consideration for, or an inducement or condition
of, any employment. Nothing contained in this Plan will be deemed to give an
employee the right to be retained in the service of the Company or to interfere
with the right of the Company to discharge, with or without cause, any employee
at any time.

            18. Status Of Plan As ERISA "Top Hat" Plan. The Plan is intended to
be an unfunded plan maintained primarily for the purpose of providing deferred
compensation for a select group of management and highly compensated employees
and will be administered and construed to effectuate this intent. Accordingly,
the Plan is subject to Title I of ERISA, but is exempt from Parts 2, 3 and 4 of
such Title.

SECTION 5. REPRESENTATIONS AND WARRANTIES OF THE COMPANY.

            The Company represents and warrants to each Purchaser that:

            Section 5.1. Organization; Power and Authority. The Company is a
corporation duly organized, validly existing and in good standing under the laws
of its jurisdiction of incorporation, and is duly qualified as a foreign
corporation and is in good standing in each jurisdiction in which such
qualification is required by law, other than those jurisdictions as to which the
failure to be so qualified or in good standing could not, individually or in the
aggregate, reasonably be expected to have a Material Adverse Effect. The Company
has the corporate power and authority to own or hold under lease the properties
it purports to own or hold under lease, to transact the business it transacts
and proposes to transact, to execute and deliver this Agreement and the Notes
and to perform the provisions hereof and thereof.

            Section 5.2. Authorization, Etc. This Agreement and the Notes have
been duly authorized by all necessary corporate action on the part of the
Company, and this Agreement constitutes, and upon execution and delivery thereof
each Note will constitute, a legal, valid and binding obligation of the Company
enforceable against the Company in accordance with its terms, except as such
enforceability may be limited by (a) applicable bankruptcy, insolvency,
reorganization, moratorium or other similar laws affecting the enforcement of
creditors' rights generally and (b) general principles of equity (regardless of
whether such enforceability is considered in a proceeding in equity or at law).

            Section 5.3. Disclosure. The Company, through its agent, BancAmerica
Robertson Stephens, has delivered to each Purchaser a copy of a Private
Placement Memorandum, dated January 1998 (the "Memorandum"), relating to the
transactions contemplated hereby. The Memorandum fairly describes, in all
material respects, the general nature of the business and principal properties
of the Company and its Subsidiaries. This Agreement, the Memorandum, the
documents, certificates or other writings identified in Schedule 5.3 and the
financial statements listed in Schedule 5.5, taken as a whole, do not contain
any untrue statement of a material fact or omit to state any material fact
necessary to make the statements therein not misleading in light of the
circumstances under which they were made. Except as disclosed in the Memorandum
or as expressly described in Schedule 5.3, or in one of the documents,
certificates or other writings identified therein, or in the financial
statements listed in Schedule 5.5, since December 31, 1996, there has been no
adverse Material change in the financial condition, operations, business,
properties or prospects of the Company or any of its Subsidiaries, taken as a
whole.

            Section 5.4. Organization and Ownership of Shares of Subsidiaries;
Affiliates. (a) Schedule 5.4 contains (except as noted therein) complete and
correct lists (1) of the Company's Subsidiaries, showing, as to each Subsidiary,
the correct name thereof, the jurisdiction of its organization, and the
percentage of shares of each class of its capital stock or similar equity
interests outstanding owned by the Company and each other Subsidiary, (2) of the
Company's Affiliates, other than Subsidiaries and (3) of the Company's directors
and senior officers.

                                      -5-
<PAGE>   12

            (b) All of the outstanding shares of capital stock or similar equity
interests of each Restricted Subsidiary shown in Schedule 5.4 as being owned by
the Company and its Subsidiaries have been validly issued, are fully paid and
nonassessable and are owned by the Company or another Subsidiary free and clear
of any Lien (except as otherwise disclosed in Schedule 5.4).

            (c) Each Restricted Subsidiary identified in Schedule 5.4 is a
corporation or other legal entity duly organized, validly existing and in good
standing under the laws of its jurisdiction of organization, and is duly
qualified as a foreign corporation or other legal entity and is in good standing
in each jurisdiction in which such qualification is required by law, other than
those jurisdictions as to which the failure to be so qualified or in good
standing could not, individually or in the aggregate, reasonably be expected to
have a Material Adverse Effect. Each such Restricted Subsidiary has the
corporate or other power and authority to own or hold under lease the properties
it purports to own or hold under lease and to transact the business it transacts
and proposes to transact.

            (d) No Restricted Subsidiary is a party to, or otherwise subject to,
any legal restriction or any agreement or instrument (other than this Agreement,
the agreements listed on Schedule 5.4 and customary limitations imposed by
corporate law statutes) restricting the ability of such Restricted Subsidiary to
pay dividends out of profits or make any other similar distributions of profits
to the Company or any of its Restricted Subsidiaries that own outstanding shares
of capital stock or similar equity interests of such Restricted Subsidiary.

            Section 5.5. Financial Statements. The Company has delivered to each
Purchaser copies of the financial statements of the Company and its Subsidiaries
listed on Schedule 5.5. All of said financial statements (including in each case
the related schedules and notes) fairly present in all material respects the
consolidated financial position of the Company and its Subsidiaries as of the
respective dates specified in such financial statements and the consolidated
results of their operations and cash flows for the respective periods so
specified and have been prepared in accordance with GAAP consistently applied
throughout the periods involved except as set forth in the notes thereto
(subject, in the case of any interim financial statements, to normal year-end
adjustments).

            Section 5.6. Compliance with Laws, Other instruments, Etc. The
execution, delivery and performance by the Company of this Agreement and the
Notes will not (a) contravene, result in any breach of, or constitute a default
under, or result in the creation of any Lien in respect of any property of the
Company or any Restricted Subsidiary under, any indenture, mortgage, deed of
trust, loan, purchase or credit agreement, lease, corporate charter or by-laws,
or any other agreement or instrument to which the Company or any Restricted
Subsidiary is bound or by which the Company or any Restricted Subsidiary or any
of their respective properties may be bound or affected, (b) conflict with or
result in a breach of any of the terms, conditions or provisions of any order,
judgment, decree, or ruling of any court, arbitrator or Governmental Authority
applicable to the Company or any Restricted Subsidiary or (c) violate any
provision of any statute or other rule or regulation of any Governmental
Authority applicable to the Company or any Restricted Subsidiary.


                                      -6-
<PAGE>   13

            Section 5.7. Governmental Authorizations, Etc. No consent, approval
or authorization of, or registration, filing or declaration with, any
Governmental Authority is required in connection with the execution, delivery or
performance by the Company of this Agreement or the Notes.

            Section 5.8. Litigation; Observance of agreements, Statutes and
Orders. (a) Except as disclosed in Schedule 5.8, there are no actions, suits or
proceedings pending or, to the knowledge of the Company, threatened against or
affecting the Company or any Restricted Subsidiary or any property of the
Company or any Restricted Subsidiary in any court or before any arbitrator of
any kind or before or by any Governmental Authority that, individually or in the
aggregate, could reasonably be expected to have a Material Adverse Effect.

            (b) Neither the Company nor any Subsidiary is in default under any
term of any agreement or instrument to which it is a party or by which it is
bound, or any order, judgment, decree or ruling of any court, arbitrator or
Governmental Authority or is in violation of any applicable law, ordinance, Rule
or regulation (including without limitation Environmental Laws) of any
Governmental Authority, which default or violation, individually or in the
aggregate, could reasonably be expected to have a Material Adverse Effect.

            Section 5.9. Taxes. The Company and its Subsidiaries have filed all
income tax returns that are required to have been filed in any jurisdiction, and
have paid all taxes shown to be due and payable on such returns and all other
taxes and assessments payable by them, to the extent such taxes and assessments
have become due and payable and before they have become delinquent, except for
any taxes and assessments (a) the amount of which is not individually or in the
aggregate Material or (b) the amount, applicability or validity of which is
currently being contested in good faith by appropriate proceedings and with
respect to which the Company or a Subsidiary, as the case may be, has
established adequate reserves in accordance with GAAP. The Company knows of no
basis for any other tax or assessment that could reasonably be expected to have
a Material Adverse Effect. The charges, accruals and reserves on the books of
the Company and its Subsidiaries in respect of Federal, state or other taxes for
all fiscal periods are adequate. The Federal income tax liabilities of the
Company and its Subsidiaries have been determined by the Internal Revenue
Service and paid for all fiscal years up to and including the fiscal year ended
December 31, 1991.

            Section 5.10. Title to Property; Leases. The Company and its
Restricted Subsidiaries have good and sufficient title to their respective
properties that individually or in the aggregate are Material, including all
such properties reflected in the most recent audited balance sheet referred to
in Section 5.5 or purported to have been acquired by the Company or any
Restricted Subsidiary after said date (except as sold or otherwise disposed of
in the ordinary course of business), in each case free and clear of Liens
prohibited by this Agreement. All leases that individually or in the aggregate
are Material are valid and subsisting and are in full force and effect in all
material respects.

            Section 5.11. Licenses, Permits, Etc. Except as disclosed in
Schedule 5.11,

            (a) the Company and its Restricted Subsidiaries own or possess all
Material licenses, permits, franchises, authorizations, patents, copyrights,
service marks, trademarks and trade names, or rights thereto;

            (b) to the best knowledge of the Company, no product of the Company
or any Restricted Subsidiary infringes in any material respect any license,
permit, franchise, authorization, patent, copyright, service mark, trademark,
trade name or other right with respect thereto owned by any other Person; and

            (c) to the best knowledge of the Company, there is no Material
violation by any Person of any right of the Company or any of its Restricted
Subsidiaries with respect to any patent, copyright, service mark, trademark,
trade name or other right with respect thereto owned or used by the Company or
any of its Restricted Subsidiaries.

            Section 5.12. Compliance with ERISA. (a) The Company and each ERISA

applicable laws in all material respects. Neither the Company nor any ERISA
Affiliate has incurred any Material liability pursuant to Title I or IV of ERISA
or the penalty or excise tax provisions of the Code relating to employee benefit
plans (as defined in Section 3 of ERISA), and no event, transaction or condition
has occurred or exists that could reasonably be expected to result in the
Incurrence of any such Material liability by the Company or any ERISA Affiliate,
or in the imposition of any Material Lien on any of the rights, properties or
assets of the Company or any ERISA Affiliate, in either case pursuant to Title I
or IV of ERISA or to such penalty or excise tax provisions or to Section
401(a)(29) or 412 of the Code.

            (b) The present value of the aggregate benefit liabilities under
each of the Plans (other than Multiemployer Plans), determined as of the end of
such Plan's most recently ended plan year on the basis of the actuarial
assumptions specified for funding purposes in such Plan's most recent actuarial
valuation report, did not exceed the aggregate current value of the assets of
such Plan allocable to such benefit liabilities by more than $5,000,000 in the
aggregate for all Plans. The term "benefit liabilities" has the meaning
specified in Section 4001 of ERISA and the terms "current value" and "present
value" have the meanings specified in Section 3 of ERISA.

            (c) The Company and its ERISA Affiliates have not incurred Material
withdrawal liabilities (and are not subject to Material contingent withdrawal
liabilities) under Section 4201 or 4204 of ERISA in respect of Multiemployer
Plans.

            (d) The expected postretirement benefit obligation (determined as of

liabilities attributable to continuation coverage mandated by Section 4980B of
the Code) of the Company and its Restricted Subsidiaries is not Material.

            (e) The execution and delivery of this Agreement and the issuance
and sale of the Notes hereunder will not involve any transaction that is subject
to the prohibitions of Section 406 of ERISA or in connection with which a tax
could be imposed pursuant to Section 4975(c)(1)(A)-(D) of the Code. The
representation by the Company in the first sentence of this Section 5.12(e) is

Person other than the Purchasers and not more than 41 other Institutional
Investors, each of which has been offered the Notes and the Guaranty Agreement
at a private sale for investment pursuant to an exemption from the registration

its behalf has taken, or will take, any action that would subject the issuance
or sale of the Notes or the delivery of the Guaranty Agreement to the
registration requirements of Section 5 of the Securities Act.

            Section 5.14. Use of Proceeds; Margin Regulations. The Company will

any margin stock; provided, however, that, pursuant to the Bank Credit
Agreement, the Company may acquire margin stock in an amount not to exceed 25%
of the value of the consolidated assets of the Company and its Subsidiaries. As
used in this Section, the terms "margin stock" and "purpose of buying or
carrying" shall have the meanings assigned to them in said Regulation G.

Company and its Restricted Subsidiaries as of December 31, 1997, since which
date there has been no Material change in the amounts, interest rates, sinking

Subsidiaries. Neither the Company nor any Restricted Subsidiary is in default
and no waiver of default is currently in effect, in the payment of any principal
or interest on any Debt of the Company or such Restricted Subsidiary and no
event or condition exists with respect to any Debt of the Company or any
Restricted Subsidiary that would permit (or that with notice or the lapse of
time, or both, would permit) one or more Persons to cause such Debt to become
due and payable before its stated maturity or before its regularly scheduled
dates of payment.

                        (a) neither the Company nor any Restricted Subsidiary

            Laws or damage to the environment emanating from, occurring on or in
            any way related to real properties now or formerly owned, leased or

            by a "qualified professional asset manager" or "QPAM" (within the
            meaning of Part V of the QPAM Exemption), no employee benefit plan's
            assets that are included in such investment fund, when combined with
            the assets of all other employee benefit plans established or

            benefit plans, each of which has been identified to the Company in
            writing pursuant to this paragraph (e); or

                        (f) the Source does not include assets of any employee
            benefit plan, other than a plan exempt from the coverage of ERISA.

            If any Purchaser or any subsequent transferee of the Notes indicates

SECTION 8. PREPAYMENT OF THE NOTES.

            Section 8.1. Required Prepayments. On March 15, 2002 and on each
March 15 thereafter to and including March 15, 2009 the Company will prepay
$6,666,666 principal amount (or such lesser principal amount as shall then be
outstanding) of the Notes at par and without payment of the Make-Whole Amount or
any premium, provided that upon any partial prepayment of the Notes pursuant to
Section 8.2 or purchase of the Notes permitted by Section 8.5 the principal
amount of each required prepayment of the Notes becoming due under this Section
8.1 on and after the date of such prepayment or purchase shall be reduced in the
same proportion as the aggregate unpaid principal amount of the Notes is reduced
as a result of such prepayment or purchase.

            Section 8.2. Optional Prepayments with Make-Whole Amount. The
Company may, at its option, upon notice as provided below, prepay at any time
all, or from time to time any part of, the Notes, in an amount not less than
$1,000,000 in the case of a partial prepayment, at 100% of the principal amount
so prepaid, together with interest accrued thereon to the date of such
prepayment, plus the Make-Whole Amount determined for the prepayment date with
respect to such 



                                      -16-
<PAGE>   23

principal amount. The Company will give each holder of Notes written notice of
each optional prepayment under this Section 8.2 not less than 30 days and not
more than 60 days prior to the date fixed for such prepayment. Each such notice
shall specify such date, the aggregate principal amount of the Notes to be
prepaid on such date, the principal amount of each Note held by such holder to
be prepaid (determined in accordance with Section 8.3), and the interest to be
paid on the prepayment date with respect to such principal amount being prepaid,
and shall be accompanied by a certificate of a Senior Financial Officer as to
the estimated Make-Whole Amount due in connection with such prepayment
(calculated as if the date of such notice were the date of the prepayment),
setting forth the details of such computation. Five Business Days prior to such
prepayment, the Company shall deliver to each holder of Notes a certificate of a
Senior Financial Officer (the "Make-Whole Amount Calculation Certificate")
specifying the method of computation and the calculation of such Make-Whole
Amount in respect of such holder's Notes as of the specified prepayment date.
The method of computation of the Make-Whole Amount in respect of the Notes set
forth in the Make-Whole Amount Calculation Certificate shall be subject to the
review and approval of the holders of the Notes and, in the case of any
disagreement between the Required Holders and the Company with respect to such
method of computation, the conclusion of the Required Holders shall, in the
absence of manifest error, be deemed binding and conclusive. The calculation of
the Make-Whole Amount in respect of the Note or Notes set forth in a Make-Whole
Amount Calculation Certificate shall also be subject to the review and approval
of the holder of such Note or Notes and, in the case of any disagreement between
such holder and the Company with respect to such calculation, the conclusion of
such holder shall, in the absence of manifest error, be deemed binding and
conclusive. It is understood and agreed that the failure of any holder to
respond to the Make-Whole Amount Calculation Certificate in respect of its Notes
by the date fixed for prepayment shall be deemed to be a concurrence by such
holder to the method of computation and the calculation of the Make-Whole Amount
in respect of such Notes.

            Section 8.3. Allocation of Partial Prepayments. In the case of each
partial prepayment of the Notes, the principal amount of the Notes to be prepaid
shall be allocated among all of the Notes at the time outstanding in proportion,
as nearly as practicable, to the respective unpaid principal amounts thereof not
theretofore called for prepayment.

            Section 8.4. Maturity; Surrender, Etc. In the case of each
prepayment of Notes pursuant to this Section 8, the principal amount of each
Note to be prepaid shall mature and become due and payable on the date fixed for
such prepayment, together with interest on such principal amount accrued to such
date and the applicable Make-Whole Amount, if any. From and after such date,
unless the Company shall fail to pay such principal amount when so due and
payable, together with the interest and Make-Whole Amount, if any, as aforesaid,
interest on such principal amount shall cease to accrue. Any Note paid or
prepaid in full shall be surrendered to the Company and canceled and shall not
be reissued, and no Note shall be issued in lieu of any prepaid principal amount
of any Note.

            Section 8.5. Purchase of Notes. The Company will not and will not
permit any Affiliate to purchase, redeem, prepay or otherwise acquire, directly
or indirectly, any of the outstanding Notes except (a) upon the payment or
prepayment of the Notes in accordance with the terms of this Agreement and the
Notes or (b) pursuant to an offer to purchase made by the Company or an
Affiliate pro rata to the holders of all Notes at the time outstanding upon the
same terms and conditions. Any such offer shall provide each holder with
sufficient information to enable it to make an informed decision with respect to
such offer, and shall remain open for at least 30 Business Days. If the holders
of more than 10% of the principal amount of the Notes then outstanding accept
such offer, the Company shall 



                                      -17-
<PAGE>   24

promptly notify the remaining holders of such fact and the expiration date for
the acceptance by holders of Notes of such offer shall be extended by the number
of days necessary to give each such remaining holder at least 30 Business Days
from its receipt of such notice to accept such offer. The Company will promptly
cancel all Notes acquired by it or any Affiliate pursuant to any payment,
prepayment or purchase of Notes pursuant to any provision of this Agreement and
no Notes may be issued in substitution or exchange for any such Notes.

            Section 8.6. Make-Whole Amount. The term "Make-Whole Amount" means,
with respect to any Note, an amount equal to the excess, if any, of the
Discounted Value of the Remaining Scheduled Payments with respect to the Called
Principal of such Note over the amount of such Called Principal, provided that
the Make-Whole Amount may in no event be less than zero. For the purposes of
determining the Make-Whole Amount, the following terms have the following
meanings:

                        "Called Principal" shall mean, with respect to any Note,
            the principal of such Note that is to be prepaid pursuant to Section
            8.2 or has become or is declared to be immediately due and payable
            pursuant to Section 12.1, as the context requires.

                        "Discounted Value" shall mean, with respect to the
            Called Principal of any Note, the amount obtained by discounting all
            Remaining Scheduled Payments with respect to such Called Principal
            from their respective scheduled due dates to the Settlement Date
            with respect to such Called Principal, in accordance with accepted
            financial practice and at a discount factor (applied on the same
            periodic basis as that on which interest on the Notes is payable)
            equal to the Reinvestment Yield with respect to such Called
            Principal.

                        "Reinvestment Yield" shall mean, with respect to the
            Called Principal of any Note, 50% over the yield to maturity implied
            by (a) the yields reported, as of 10:00 a.m. (New York City time) on
            the fifth Business Day preceding the Settlement Date with respect to
            such Called Principal, on the applicable "PX" page of the Bloomberg
            Financial Market Service's Screen (or such other page as may replace
            the applicable PX page of the Bloomberg Financial Market Service's
            Screen) for actively traded U.S. Treasury Securities having a
            maturity equal to the Remaining Average Life of such Called
            Principal as of such Settlement Date, or (b) if such yields are not
            reported as of such time or the yields reported as of such time are
            not ascertainable, the Treasury Constant Maturity Series Yields
            reported, for the latest day for which such yields have been so
            reported as of the fifth Business Day preceding the Settlement Date
            with respect to such Called Principal, in Federal Reserve
            Statistical Release H.15 (519) (or any comparable successor
            publication) for actively traded U.S. Treasury Securities having a
            constant maturity equal to the Remaining Average Life of such Called
            Principal as of such Settlement Date. Such implied yield in clauses
            (a) and (b) above will be determined, if necessary, by (1)
            converting U.S. Treasury bill quotations to bond-equivalent yields
            in accordance with accepted financial practice and (2) interpolating
            linearly between (i) the actively traded U.S. Treasury Security with
            the maturity closest to and greater than the Remaining Average Life
            and (2) the 



                                      -18-
<PAGE>   25

            actively traded U.S. Treasury Security with the maturity closest to
            and less than the Remaining Average Life.

                        "Remaining Average Life" shall mean, with respect to any
            Called Principal, the number of years (calculated to the nearest
            one-twelfth year) obtained by dividing (a) such Called Principal
            into (b) the sum of the products obtained by multiplying (1) the
            principal component of each Remaining Scheduled Payment with respect
            to such Called Principal by (2) the number of years (calculated to
            the nearest one-twelfth year) that will elapse between the
            Settlement Date with respect to such Called Principal and the
            scheduled due date of such Remaining Scheduled Payment.

                        "Remaining Scheduled Payments" shall mean, with respect
            to the Called Principal of any Note, all payments of such Called
            Principal and interest thereon that would be due after the
            Settlement Date with respect to such Called Principal if no payment
            of such Called Principal were made prior to its scheduled due date,
            provided that if such Settlement Date is not a date on which
            interest payments are due to be made under the terms of the Notes,
            then the amount of the next succeeding scheduled interest payment
            will be reduced by the amount of interest accrued to such Settlement
            Date and required to be paid on such Settlement Date pursuant to
            Section 8.2 or 12.1.

                        "Settlement Date" shall mean, with respect to the Called
            Principal of any Note, the date on which such Called Principal is to
            be prepaid pursuant to Section 8.2 or has become or is declared to
            be immediately due and payable pursuant to Section 12.1, as the
            context requires.

SECTION 9. AFFIRMATIVE COVENANTS.

            The Company covenants that so long as any of the Notes are
outstanding:

            Section 9.1. Compliance with Law. The Company will, and will cause
each of its Subsidiaries to, comply with all laws, ordinances or governmental
rules or regulations to which each of them is subject, including, without
limitation, Environmental Laws, and will obtain and maintain in effect all
licenses, certificates, permits, franchises and other governmental
authorizations necessary to the ownership of their respective properties or to
the conduct of their respective businesses, in each case to the extent necessary
to ensure that non-compliance with such laws, ordinances or governmental rules
or regulations or failures to obtain or maintain in effect such licenses,
certificates, permits, franchises and other governmental authorizations could
not reasonably be expected, individually or in the aggregate, to have a Material
Adverse Effect.

            Section 9.2. Insurance. The Company will, and will cause each of its
Restricted Subsidiaries to, maintain, with financially sound and reputable
insurers, insurance with respect to their respective properties and businesses
against such casualties and contingencies, of such types, on such terms and in
such amounts (including deductibles, co-insurance and self-insurance, if
adequate reserves are maintained with respect thereto) as is customary in 



                                      -19-
<PAGE>   26

the case of entities of established reputations engaged in the same or a similar
business and similarly situated.

            Section 9.3. Maintenance of Properties. The Company will, and will
cause each of its Restricted Subsidiaries to, maintain and keep, or cause to be
maintained and kept, their respective properties in good repair, working order
and condition (other than ordinary wear and tear), so that the business carried
on in connection therewith may be properly conducted at all times, provided that
this Section shall not prevent the Company or any Restricted Subsidiary from
discontinuing the operation and the maintenance of any of its properties if such
discontinuance is desirable in the conduct of its business and the Company has
concluded that such discontinuance could not reasonably be expected,
individually or in the aggregate, to have a Material Adverse Effect.

            Section 9.4. Payment of Taxes and Claims. The Company will, and will
cause each of its Subsidiaries to, file all tax returns required to be filed in
any jurisdiction and to pay and discharge all taxes shown to be due and payable
on such returns and all other taxes, assessments, governmental charges, or
levies imposed on them or any of their properties, assets, income or franchises,
to the extent such taxes and assessments have become due and payable and before
they have become delinquent and all claims for which sums have become due and
payable that have or might become a Lien on properties or assets of the Company
or any Subsidiary, provided that neither the Company nor any Subsidiary need pay
any such tax or assessment or claims if (a) the amount, applicability or
validity thereof is contested by the Company or such Subsidiary on a timely
basis in good faith and in appropriate proceedings, and the Company or a
Subsidiary has established adequate reserves therefor in accordance with GAAP on
the books of the Company or such Subsidiary or (b) the nonpayment of any such
taxes or assessments could not reasonably be expected, individually or in the
aggregate, to have a Material Adverse Effect.

            Section 9.5. Corporate Existence, Etc. The Company will at all times
preserve and keep in full force and effect its corporate existence. Subject to
Sections 10.7, 10.8 and 10.9, the Company will at all times preserve and keep in
full force and effect the corporate existence of each of its Subsidiaries
(unless merged into the Company or a Wholly-Owned Restricted Subsidiary) and all
rights and franchises of the Company and its Subsidiaries unless, in the good
faith judgment of the Company, the termination of or failure to preserve and
keep in full force and effect such corporate existence, right or franchise would
not, individually or in the aggregate, have a Material Adverse Effect.

            Section 9.6. Additional Guarantors. (a) The Company shall promptly,
and in any event within three Business Days after (1) a Subsidiary becomes a
Material Subsidiary, (2) the formation or acquisition of a new Subsidiary that
is a Material Subsidiary or (3) the occurrence of any other event creating a new
Subsidiary that is a Material Subsidiary, cause such Material Subsidiary to
execute and deliver a supplement to the Guaranty Agreement in the form of
Exhibit A to the Guaranty Agreement.

            (b) Concurrently with the execution and delivery by a Material
Subsidiary of a supplement to the Guaranty Agreement, the Company shall cause
such Material Subsidiary to 



                                      -20-

deliver to each holder of Notes (1) such documents and evidence with respect to
such Material Subsidiary as any holder may reasonably request in order to
establish the existence and good standing of such Material Subsidiary and
evidence that the Board of Directors of such Material Subsidiary has adopted
resolutions authorizing the execution and delivery of a supplement to the
Guaranty Agreement, (2) evidence of compliance with such Material Subsidiary's
outstanding debt instruments in the form of (i) a compliance certificate from

            Section 12.1. Acceleration. (a) If an Event of Default with respect
to the Company described in paragraph (g) or (h) of Section 11 (other than an
Event of Default described in clause (1) of paragraph (g) or described in clause
(6) of paragraph (g) by virtue of the fact that such clause encompasses clause
(1) of paragraph (g)) exists, all the Notes then outstanding shall automatically
become immediately due and payable.

            (b) If any other Event of Default exists, any holder or holders of
more than 25% in principal amount of the Notes at the time outstanding may at
any time at its or their option, by notice or notices to the Company, declare
all the Notes then outstanding to be immediately due and payable.

            (c) If any Event of Default described in paragraph (a) or (b) of
Section 11 exists, any holder or holders of Notes at the time outstanding

protest or further notice, all of which are hereby waived. The Company

right to maintain its investment in the Notes free from repayment by the Company
(except as herein specifically provided for) and that the provision for payment
of a Make-Whole Amount by the Company in the event that the Notes are prepaid or
are accelerated as a result of an Event of Default, is intended to provide
compensation for the deprivation of such right under such circumstances.

            Section 12.2. Other Remedies. If any Event of Default exists, and
irrespective of whether any Notes have become or have been declared immediately
due and payable under Section 12.1, the holder of any Note at the time
outstanding may proceed to protect and enforce the rights of such holder by an
action at law, suit in equity or other appropriate proceeding, whether for the
specific performance of any agreement contained herein or in any Note, or for an
injunction against a violation of any of the terms hereof or thereof, or in aid
of the exercise of any power granted hereby or thereby or by law or otherwise.

            Section 12.3. Rescission. At any time after any Notes have been
declared due and payable pursuant to clause (b) or (c) of Section 12.1, the
holders of not less than 76% in principal amount of the Notes then outstanding,
by written notice to the Company, may rescind and annul any such declaration and
its consequences if (a) the Company has paid all overdue interest on the Notes,
all principal of and Make-Whole Amount, if any, on any Notes that are due and
payable and are unpaid other than by reason of such declaration, and all
interest on such overdue principal and Make-Whole Amount, if any, and (to the
extent 


                                      -31-
<PAGE>   38

permitted by applicable law) any overdue interest in respect of the Notes, at
the Default Rate, (b) all Events of Default and Defaults, other than non-payment
of amounts that have become due solely by reason of such declaration, have been
cured or have been waived pursuant to Section 17, and (c) no judgment or decree
has been entered for the payment of any monies due pursuant hereto or to the
Notes. No rescission and annulment under this Section 12.3 will extend to or
affect any subsequent Event of Default or Default or impair any right consequent
thereon.

            Section 12.4. No Waivers or Election of Remedies, Expenses, Etc. No
course of dealing and no delay on the part of any holder of any Note in
exercising any right, power or remedy shall operate as a waiver thereof or
otherwise prejudice such holder's rights, powers or remedies. No right, power or
remedy conferred by this Agreement or by any Note upon any holder thereof shall
be exclusive of any other right, power or remedy referred to herein or therein
or now or hereafter available at law. in equity, by statute or otherwise.

the payment of any Note, and may be relied upon by any subsequent holder of a
Note, regardless of any investigation made at any time by or on behalf of such
Purchaser or any other holder of a Note. All statements contained in any
certificate or other instrument delivered by or on behalf of the Company
pursuant to this Agreement shall be deemed representations and warranties of the
Company under this Agreement. Subject to the preceding sentence, this Agreement
and the Notes embody the entire agreement and understanding between each
Purchaser and the Company and supersede all prior agreements and understandings
relating to the subject matter hereof.

SECTION 17. AMENDMENT AND WAVIER.

            Section 17.1. Requirements. This Agreement and the Notes may be
amended, and the observance of any term hereof or of the Notes may be waived
(either retroactively or prospectively), with (and only with) the written
consent of the Company and the Required Holders, except that (a) no amendment or
waiver of any of the provisions of Section 1, 2, 3, 4, 5, 6 or 21 hereof, or any
defined term (as it is used therein), will be effective as to any Purchaser
unless consented to by such Purchaser in writing, and (b) no such amendment or
waiver may, without the written consent of the holder of each Note at the time
outstanding affected thereby, (1) subject to the provisions of Section 12
relating to acceleration or rescission, change the amount or time of any
prepayment or payment of principal of, or reduce the rate or change the time of
payment or method of computation of interest or of the Make-Whole Amount on, the
Notes, (2) change the percentage of the principal amount of the Notes the
holders of which are required to consent to any such amendment or waiver, or (3)
amend any of Sections 8, 11(a), 11(b), 12, 17 or 20.

            Section 17.2.  Solicitation of Holders of Notes.

            (a) Solicitation. The Company will provide each holder of the Notes
(irrespective of the amount of Notes then owned by it) with sufficient
information, sufficiently far in advance of the date a decision is required, to
enable such holder to make an informed and considered decision with respect to
any proposed amendment, waiver or consent in respect of any of the provisions
hereof or of the Notes. The Company will deliver executed or true and correct
copies of each amendment, waiver or consent effected pursuant to the provisions
of this Section 17 to each holder of outstanding Notes promptly following the
date on which it is executed and delivered by, or receives the consent or
approval of, the requisite holders of Notes.

                                      -35-
<PAGE>   42

            (b) Payment. The Company will not directly or indirectly pay or
cause to be paid any remuneration, whether by way of supplemental or additional
interest, fee or otherwise, or grant any security, to any holder of Notes as
consideration for or as an inducement to the entering into by any holder of
Notes of any waiver or amendment of any of the terms and provisions hereof
unless such remuneration is concurrently paid, or security is concurrently
granted, on the same terms, ratably to each holder of Notes then outstanding
even if such holder did not consent to such waiver or amendment.

            Section 17.3. Binding Effect, Etc. Any amendment or waiver consented
to as provided in this Section 17 applies equally to all holders of Notes and is
binding upon them and upon each future holder of any Note and upon the Company
without regard to whether such Note has been marked to indicate such amendment
or waiver. No such amendment or waiver will extend to or affect any obligation,
covenant, agreement, Default or Event of Default not expressly amended or waived
or impair any right consequent thereon. No course of dealing between the Company
and the holder of any Note nor any delay in exercising any rights hereunder or
under any Note shall operate as a waiver of any rights of any holder of such
Note. As used herein, the term "this Agreement" and references thereto shall
mean this Agreement as it may from time to time be amended or supplemented.

            Section 17.4. Notes Held by Company, Etc. Solely for the purpose of
determining whether the holders of the requisite percentage of the aggregate
principal amount of Notes then outstanding approved or consented to any
amendment, waiver or consent to be given under this Agreement or the Notes, or
have directed the taking of any action provided herein or in the Notes to be
taken upon the direction of the holders of a specified percentage of the
aggregate principal amount of Notes then outstanding, Notes directly or
indirectly owned by the Company or any of its Affiliates shall be deemed not to
be outstanding.

SECTION 18.   NOTICES.

            All notices and communications provided for hereunder shall be in
writing and sent (a) by telefacsimile if the sender on the same day sends a
confirming copy of such notice by a recognized overnight delivery service
(charges prepaid), or (b) by registered or certified mail with return receipt
requested (postage prepaid), or (c) by a recognized overnight delivery service
(with charges prepaid). Any such notice must be sent:

                        (1) if to a Purchaser or such Purchaser's nominee, to
            such Purchaser or such Purchaser's nominee at the address specified
            for such communications below such Purchaser's signature at the foot
            of this Agreement, or at such other address as such Purchaser or
            such Purchaser's nominee shall have specified to the Company in
            writing,

                        (2) if to any other holder of any Note, to such holder
            at such address as such other holder shall have specified to the
            Company in writing, or

                                      -36-
<PAGE>   43

                        (3) if to the Company, to the Company at its address set
            forth at the beginning hereof to the attention of Chief Financial
            Officer, or at such other address as the Company shall have
            specified to the holder of each Note in writing.

Notices under this Section 18 will be deemed given only when actually received.

SECTION 19.  REPRODUCTION OF DOCUMENTS.

            This Agreement and all documents relating hereto, including, without
limitation, (a) consents, waivers and modifications that may hereafter be
executed, (b) documents received by each Purchaser at the Closing (except the
Notes themselves), and (c) financial statements, certificates and other
information previously or hereafter furnished to each Purchaser, may be
reproduced by such Purchaser by any photographic, photostatic, microfilm,
microcard, miniature photographic or other similar process and such Purchaser
may destroy any original document so reproduced. The Company agrees and
stipulates that, to the extent permitted by applicable law, any such
reproduction shall be admissible in evidence as the original itself in any
judicial or administrative proceeding (whether or not the original is in
existence and whether or not such reproduction was made by such Purchaser in the
regular course of business) and any enlargement, facsimile or further
reproduction of such reproduction shall likewise be admissible in evidence. This
Section 19 shall not prohibit the Company or any other holder of Notes from
contesting any such reproduction to the same extent that it could contest the
original, or from introducing evidence to demonstrate the inaccuracy of any such
reproduction.

SECTION 20. CONFIDENTIAL INFORMATION.

            For the purposes of this Section 20, "Confidential Information"
means information delivered to any Purchaser by or on behalf of the Company or
any Subsidiary in connection with the transactions contemplated by or otherwise
pursuant to this Agreement that is proprietary in nature and that was clearly
marked or labeled or otherwise adequately identified when received by such
Purchaser as being confidential information of the Company or such Subsidiary,
provided that such term does not include information that (a) was publicly known
or otherwise known to such Purchaser prior to the time of such disclosure, (b)
subsequently becomes publicly known through no act or omission by such Purchaser
or any Person acting on such Purchaser' s behalf, (c) otherwise becomes known to
such Purchaser other than through disclosure by the Company or any Subsidiary or
(d) constitutes financial statements delivered to such Purchaser under Section
7.1 that are otherwise publicly available. Each Purchaser will maintain the
confidentiality of such Confidential Information in accordance with procedures
adopted by such Purchaser in good faith to protect confidential information of
third parties delivered to such Purchaser, provided that such Purchaser may
deliver or disclose Confidential Information to (1) such Purchaser's directors,
trustees, officers, employees, agents, attorneys and affiliates (to the extent
such disclosure reasonably relates to the administration of the investment
represented by such Purchaser's Notes), (2) such Purchaser's financial advisors
and other professional advisors who agree to hold confidential the Confidential
Information substantially in 



                                      -37-
<PAGE>   44

accordance with the terms of this Section 20, (3) any other holder of any Note,
(4) any Institutional Investor to which such Purchaser sells or offers to sell
such Note or any part thereof or any participation therein (if such Person has
agreed in writing prior to its receipt of such Confidential Information to be
bound by the provisions of this Section 20), (5) any Person from which such
Purchaser offers to purchase any Security of the Company (if such Person has
agreed in writing prior to its receipt of such Confidential Information to be
bound by the provisions of this Section 20), (6) any Federal or state regulatory
authority having jurisdiction over such Purchaser, (7) the National Association
of Insurance Commissioners or any similar organization, or any nationally
recognized rating agency that requires access to information about such
Purchaser' s investment portfolio, or (8) any other Person to which such
delivery or disclosure may be necessary or appropriate (i) to effect compliance
with any law, Rule, regulation or order applicable to such Purchaser, (ii) in
response to any subpoena or other legal process, (iii) in connection with any
litigation to which such Purchaser is a party or (iv) if an Event of Default has
occurred and is continuing, to the extent such Purchaser may reasonably
determine such delivery and disclosure to be necessary or appropriate in the
enforcement or for the protection of the rights and remedies under such
Purchaser's Notes and this Agreement. Each holder of a Note, by its acceptance
of a Note, will be deemed to have agreed to be bound by and to be entitled to
the benefits of this Section 20 as though it were a party to this Agreement. On
reasonable request by the Company in connection with the delivery to any holder
of a Note of information required to be delivered to such holder under this
Agreement or requested by such holder (other than a holder that is a party to
this Agreement or its nominee), such holder will enter into an agreement with
the Company embodying the provisions of this Section 20.

SECTION 21. SUBSTITUTION OF A PURCHASER.

            Each Purchaser shall have the right to substitute any one of such
Purchaser's Affiliates as the purchaser of the Notes that such Purchaser has
agreed to purchase hereunder, by written notice to the Company, which notice
shall be signed by both such Purchaser and such Purchaser's Affiliate, shall
contain such Affiliate's agreement to be bound by this Agreement and shall
contain a confirmation by such Affiliate of the accuracy with respect to it of
the representations set forth in Section 6. Upon receipt of such notice,
wherever the word "Purchaser" is used in this Agreement (other than in this
Section 21), such word shall be deemed to refer to such Affiliate in lieu of
such Purchaser. In the event that such Affiliate is so substituted as a
purchaser hereunder and such Affiliate thereafter transfers to such Purchaser
all of the Notes then held by such Affiliate, upon receipt by the Company of
notice of such transfer, wherever the word "Purchaser" is used in this Agreement
(other than in this Section 21), such word shall no longer be deemed to refer to
such Affiliate, but shall refer to such Purchaser, and such Purchaser shall have
all the rights of an original holder of the Notes under this Agreement.

SECTION 22. MISCELLANEOUS.

            Section 22.1. Successors and Assigns. All covenants and other
agreements contained in this Agreement by or on behalf of any of the parties
hereto bind and inure to the benefit of their respective successors and assigns
(including, without limitation, any subsequent holder of a Note) whether so
expressed or not.

            Section 22.2. Payments Due on Non-Business Days. Anything in this
Agreement or the Notes to the contrary notwithstanding, any payment of principal
of or Make-Whole Amount or interest on any Note that is due on a date other than
a Business Day shall be made on the next succeeding Business Day without
including the additional days elapsed in the computation of the interest payable
on such next succeeding Business Day.

            Section 22.3. Severability. Any provision of this Agreement that is
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall (to the full extent permitted by law)
not invalidate or render unenforceable such provision in any other jurisdiction.

            Section 22.4. Construction. Each covenant contained herein shall be
construed (absent express provision to the contrary) as being independent of
each other covenant contained herein, so that compliance with any one covenant
shall not (absent such an express contrary provision) be deemed to excuse
compliance with any other covenant. Where any provision herein refers to action
to be taken by any Person, or which such Person is prohibited from taking, such
provision shall be applicable whether such action is taken directly or
indirectly by such Person.

            Where the character or amount of any asset or liability or item of
income or expense is required to be determined or any consolidation or other
accounting computation is required to be made for the purposes of this
Agreement, the same shall be done in accordance with GAAP, to the extent
applicable, except where such principles are inconsistent with the requirements
of this Agreement.

            Section 22.5. Counterparts. This Agreement may be executed in any
number of counterparts, each of which shall be an original but all of which
together shall constitute one instrument. Each counterpart may consist of a
number of copies hereof, each signed by less than all, but together signed by
all, of the parties hereto.

            Section 22.6. Governing Law. This Agreement shall be construed and
enforced in accordance with, and the rights of the parties shall be governed by,
the law of the State of Illinois excluding choice-of-law principles of the law
of such State that would require the application of the laws of a jurisdiction
other than such State.

            The execution hereof by the Purchasers shall constitute a contract
among the Company and the Purchasers for the uses and purposes hereinabove set
forth. This Agreement may be executed in any number of counterparts, each
executed counterpart constituting an original but all together only one
agreement.

                                            Very truly yours,

quarter, and in making such determination, if any agreement relating to such
Swap provides for the netting of amounts payable by and to such Person
thereunder or if any such agreement provides for the simultaneous payment of
amounts by and to such Person, then in each such case, the amount of such
obligation shall be the net amount so determined. For purposes of this
Agreement, any such interest rate swap, currency swap, or other similar
obligation which is or will be entered into and is being or will be used by such
Person in the ordinary course of its business to hedge an existing or future
risk or exposure of such Person in respect of its liabilities or assets (and not

            "Transfer" shall mean, with respect to any Person, any transaction
in which such Person sells, conveys, transfers or leases (as lessor) any of its
property, including, without limitation, Subsidiary Stock. or purposes of
determining the application of the Net Proceeds Amount in respect of any
Transfer, the Company may designate any Transfer as one or more separate
Transfers each yielding a separate Net Proceeds Amount. n any such case, (a) the
Disposition Value of any property subject to each such separate Transfer and (b)
the amount of Consolidated Total Assets attributable to any property subject to
each such separate Transfer shall be determined by ratably allocating the
aggregate Disposition Value of, and the aggregate Consolidated Total Assets
attributable to, all property subject to all such separate Transfers to each
such separate Transfer on a proportionate basis.

            "Unrestricted Subsidiary" shall mean any Subsidiary which is not a
Restricted Subsidiary.

            "Wholly-Owned" when used in connection with any Subsidiary shall
mean, at any time, any Subsidiary one hundred percent (100%) of all of the
equity interests (except directors' qualifying shares) and voting interests of

                              ENVIRONMENTAL MATTERS


Granite Construction in the normal course of business utilizes petroleum
(hydrocarbon) products which may be considered hazardous materials when
encountered at regulatory levels established by the Federal EPA or the Regional
State EPA. The utilization of these asphalt products, diesel, and gasoline over
the years has the potential of creating exposure to environmental clean up
requirements. All underground tanks meet current requirements. There is no
pending governmental ordered clean up. However, the following represents
estimates based on construction industry housekeeping practices as encountered
during our normal course of business. Except as indicated with an "*", these
costs do not represent actual identified exposures.

exists, the principal of this Note may be declared or otherwise become due and
payable in the manner, at the price (including any applicable Make-Whole Amount)

the rights of the parties shall be governed by, the law of the State of
Illinois, excluding choice-of-law principles of the law of such State that would

                       FORM OF OPINION OF SPECIAL COUNSEL
                        TO THE COMPANY AND THE GUARANTORS


            The closing opinion of Gray Cary Ware & Freidenrich, special counsel
for the Company and the Guarantors, which is called for by Section 4.5(a) of the
Agreement, shall be dated the date of the Closing and addressed to each
Purchaser, shall be satisfactory in scope and form to each Purchaser and shall
be to the effect that:

                        1. The Company is a corporation, duly incorporated,
            validly existing and in good standing under the laws of the State of
            Delaware, has the corporate power and the corporate authority to
            execute and perform the Agreement and to issue the Notes and has the
            full corporate power and the corporate authority to conduct the
            activities in which it is now engaged and is duly licensed or
            qualified and is in good standing as a foreign corporation in each
            jurisdiction in which the character of the properties owned or
            leased by it or the nature of the business transacted by it makes
            such licensing or qualification necessary.

                        2. Each Restricted Subsidiary is a corporation or other
            business entity duly organized, validly existing and in good
            standing under the laws of its jurisdiction of organization and is
            duly licensed or qualified and is in good standing in each
            jurisdiction in which the character of the properties owned or
            leased by it or the nature of the business transacted by it makes
            such licensing or qualification necessary and all of the issued and
            outstanding shares of capital stock or other equity interests of
            each such Restricted Subsidiary have been duly issued, are fully
            paid and non-assessable and are owned by the Company, by one or more
            Subsidiaries, or by the Company and one or more Subsidiaries.

                        3. The Agreement has been duly authorized by all
            necessary corporate action on the part of the Company, has been duly
            executed and delivered by the Company and constitutes the legal,
            valid and binding contract of the Company enforceable in accordance
            with its terms, subject to bankruptcy, insolvency, fraudulent
            conveyance and similar laws affecting creditors' rights generally,
            and general principles of equity (regardless of whether the
            application of such principles is considered in a proceeding in
            equity or at law).

                        4. The Notes have been duly authorized by all necessary
            corporate action on the part of the Company, have been duly executed
            and delivered by the Company and constitute the legal, valid and
            binding obligations of the Company enforceable in accordance with
            their terms, subject to bankruptcy, insolvency, fraudulent
            conveyance and similar laws affecting creditors' rights generally,
            and general principles of equity (regardless of whether the
            application of such principles is considered in a proceeding in
            equity or at law).

                        5. No approval, consent or withholding of objection on
            the part of, or filing, registration or qualification with, any
            governmental body, Federal or state, is



                                 EXHIBIT 4.5(a)
                          (to Note Purchase Agreement)


<PAGE>   92



            necessary in connection with the execution and delivery by the
            Company of the Agreement or the Notes.

                        6. The issuance and sale of the Notes and the execution,
            delivery and performance by the Company of the Agreement do not
            conflict with or result in any breach of any of the provisions of or
            constitute a default under or result in the creation or imposition
            of any Lien upon any of the property of the Company pursuant to the
            provisions of the Certificate of Incorporation or By-laws of the
            Company or any agreement or other instrument known to such counsel
            to which the Company is a party or by which the Company may be
            bound.

                        7. Each Guarantor has the power and the authority to
            execute, deliver and perform the Guaranty Agreement and has the full
            power and the authority to conduct the activities in which it is now
            engaged.

                        8. The Guaranty Agreement has been duly authorized by
            all necessary action on the part of each Guarantor, has been duly
            executed and delivered by each Guarantor and constitutes the legal,
            valid and binding contract of each Guarantor enforceable in
            accordance with its terms, subject to bankruptcy, insolvency,
            fraudulent conveyance and similar laws affecting creditors' rights
            generally, and general principles of equity (regardless of whether
            the application of such principles is considered in a proceeding in
            equity or at law).

                        9. No approval, consent or withholding of objection on
            the part of, or filing, registration or qualification with, any
            governmental body, Federal or state, is necessary in connection with
            the execution and delivery by any Guarantor of the Guaranty
            Agreement.

                        10. The execution, delivery and performance by each
            Guarantor of the Guaranty Agreement do not conflict with or result
            in any breach of any of the provisions of or constitute a default
            under or result in the creation or imposition of any Lien upon any
            of the property of such Guarantor pursuant to the provisions of the
            charter documents or by-laws of such Guarantor or any agreement or
            other instrument known to such counsel to which such Guarantor is a
            party or by which such Guarantor may be bound.

                        11. The issuance, sale and delivery of the Notes and the
            issuance and delivery of the Guaranty Agreement under the
            circumstances contemplated by the Agreement do not, under existing
            law, require the registration of the Notes or the Guaranty Agreement
            under the Securities Act or the qualification of an indenture under
            the Trust Indenture Act of 1939, as amended.

            The opinion of Gray Cary Ware & Freidenrich shall cover such other
matters relating to the sale of the Notes as any Purchaser may reasonably
request. With respect to matters of fact on which such opinion is based, such
counsel shall be entitled to rely on appropriate certificates of public
officials and officers of the Company and the Guarantors.

                        1. The Company is a corporation, validly existing and in
            good standing under the laws of the State of Delaware and has the
            corporate power and the corporate authority to execute and deliver
            the Agreement and to issue the Notes.

                        2. The Agreement has been duly authorized by all
            necessary corporate action on the part of the Company, has been duly
            executed and delivered by the Company and constitutes the legal,
            valid and binding contract of the Company enforceable in accordance
            with its terms, subject to bankruptcy, insolvency, fraudulent
            conveyance and similar laws affecting creditors' rights generally,
            and general principles of equity (regardless of whether the
            application of such principles is considered in a proceeding in
            equity or at law).

                        3. The Notes have been duly authorized by all necessary
            corporate action on the part of the Company, and the Notes being
            delivered on the date hereof have been duly executed and delivered
            by the Company and constitute the legal, valid and binding
            obligations of the Company enforceable in accordance with their
            terms, subject to bankruptcy, insolvency, fraudulent conveyance and
            similar laws affecting creditors' rights generally, and general
            principles of equity (regardless of whether the application of such
            principles is considered in a proceeding in equity or at law).

                        4. The issuance, sale and delivery of the Notes under
            the circumstances contemplated by the Agreement do not, under
            existing law, require the registration of the Notes under the
            Securities Act or the qualification of an indenture under the Trust
            Indenture Act of 1939, as amended.

            The opinion of Chapman and Cutler shall also state that the opinion
of Gray Cary Ware & Freidenrich is satisfactory in scope and form to Chapman and
Cutler and that, in their opinion, the Purchasers are justified in relying
thereon.

            In rendering the opinion set forth in paragraph 1 above, Chapman and
Cutler may rely, as to matters referred to in paragraph 1, solely upon an
examination of the Certificate of Incorporation certified by, and a certificate
of good standing of the Company from, the Secretary of State of the State of
Delaware, the By-laws of the Company and the general business corporation law of
the State of Delaware. The opinion of Chapman and Cutler is limited to the
laws of the State of Illinois, the general business corporation law of the State
of Delaware and the Federal laws of the United States.

            With respect to matters of fact upon which such opinion is based,
Chapman and Cutler may rely on appropriate certificates of public officials and
officers of the Company and upon representations of the Company and the
Purchasers delivered in connection with the issuance and sale of the Notes.

                          SUBSIDIARY GUARANTY AGREEMENT


           Re:            $60,000,000 6.54% Senior Notes
                               Due March 15, 2010
                                       of
                        Granite Construction Incorporated
                   -------------------------------------------

     This SUBSIDIARY GUARANTY AGREEMENT dated as of March 1, 1998 (the or this
"Guaranty") is entered into on a joint and several basis by each of the
undersigned, together with any entity which may become a party hereto by
execution and delivery of a Subsidiary Guaranty Supplement in substantially the
form set forth as Exhibit A hereto (a "Guaranty Supplement") (which parties are
hereinafter referred to individually as a "Guarantor" and collectively as the
"Guarantors").

                                    RECITALS

     A.   Each Guarantor is a subsidiary of Granite Construction Incorporated, a
Delaware corporation (the "Company"), and a Material Subsidiary (as defined in
the hereinafter defined Note Agreement).

     B.   In order to refinance existing Debt (as defined in the Note Agreement)
and for general corporate purposes, the Company has entered into that certain
Note Purchase Agreement dated as of March 1, 1998 (the "Note Agreement") between
the Company and each of the purchasers named on Schedule A attached to said Note
Agreement (the "Initial Note Purchasers," together with their successors and
assigns, the "Holders"), providing for, among other things, the issue and sale
by the Company to the Initial Note Purchasers of the Company's 6.54% Senior
Notes, due March 15, 2010 in the aggregate principal amount of $60,000,000 (the
"Notes").

     C.   The Initial Note Purchasers have required as a condition of their
purchase of the Notes that the Company cause each of the undersigned to enter
into this Guaranty and to cause each from time to time Material Subsidiary to
enter into a Guaranty Supplement, in each case as security for the Notes, and
the Company has agreed to cause each of the undersigned to execute this Guaranty
and to cause each from time to time Material Subsidiary to execute a Guaranty
Supplement, in each case in order to induce the Initial Note Purchasers to
purchase the Notes and thereby benefit the Company and its Subsidiaries (as
defined in the Note Agreement) by providing funds to enable the Company to
refinance existing Debt and to enable the Company and its Subsidiaries to have
funds available for general corporate purposes.

     Now, THEREFORE, as required by Section 4.4 of the Note Agreement and in
consideration of the premises and other good and valuable consideration, the
receipt and sufficiency whereof are hereby acknowledged, each Guarantor does
hereby covenant and agree, jointly and severally, as follows:

<PAGE>   4

SECTION 1.   DEFINITIONS.

     Capitalized terms used herein shall have the meanings set forth in the Note
Agreement unless herein defined or the context shall otherwise require.

SECTION 2.   GUARANTY OF NOTES AND NOTE AGREEMENT.

     (a)  Each Guarantor jointly and severally does hereby irrevocably,
absolutely and unconditionally guarantee unto the Holders: (1) the full and
prompt payment of the principal of, premium, if any, and interest on the Notes
from time to time outstanding, as and when such payments shall become due and
payable whether by lapse of time, upon redemption or prepayment, by extension or
by acceleration or declaration or otherwise (including (to the extent legally
enforceable) interest due on overdue payments of principal, premium, if any, or
interest at the rate set forth in the Notes) in Federal or other immediately
available funds of the United States of America which at the time of payment or
demand therefor shall be legal tender for the payment of public and private
debts, (2) the full and prompt performance and observance by the Company of each
and all of the obligations, covenants and agreements required to be performed or
owed by the Company under the terms of the Notes and the Note Agreement and (3)
the full and prompt payment, upon demand by any Holder of all costs and
expenses, legal or otherwise (including reasonable attorneys' fees), if any, as
shall have been expended or incurred in the protection or enforcement of any
rights, privileges or liabilities in favor of the Holders under or in respect of
the Notes, the Note Agreement or under this Guaranty or in any consultation or
action in connection therewith or herewith.

     (b)  The liability of each Guarantor under this Guaranty shall not exceed
an amount equal to a maximum amount as will, after giving effect to such maximum
amount and all other liabilities of such Guarantor, contingent or otherwise,
result in the obligations of such Guarantor hereunder not constituting a
fraudulent transfer, obligation or conveyance.

SECTION 3.   GUARANTY OF PAYMENT AND PERFORMANCE.

     This is a guarantee of payment and performance and each Guarantor hereby
waives, to the fullest extent permitted by law, any right to require that any
action on or in respect of any Note or the Note Agreement be brought against the
Company or any other Person or that resort be had to any direct or indirect
security for the Notes or for this Guaranty or any other remedy. Any Holder may,
at its option, proceed hereunder against any Guarantor in the first instance to
collect monies when due, the payment of which is guaranteed hereby, without
first proceeding against the Company or any other Person and without first
resorting to any direct or indirect security for the Notes or for this Guaranty
or any other remedy. The liability of each Guarantor hereunder shall in no way
be affected or impaired by any acceptance by any Holder of any direct or
indirect security for, or other guaranties of, any Debt, liability or obligation
of the Company or any other Person to any Holder or by any failure, delay,
neglect or omission by any Holder to realize upon or protect any such
guarantees, Debt, liability or obligation or any notes or other instruments 
evidencing the 


                                      -2-
<PAGE>   5

same or any direct or indirect security therefor or by any approval, consent,
waiver, or other action taken, or omitted to be taken by any such Holder.

     The covenants and agreements on the part of the Guarantors herein contained
shall take effect as joint and several covenants and agreements, and references
to the Guarantors shall take effect as references to each of them and none of
them shall be released from liability hereunder by reason of the guarantee
ceasing to be binding as a continuing security on any other of them.

SECTION 4.   GENERAL PROVISIONS RELATING TO THE GUARANTY.

     (a)  Each Guarantor hereby consents and agrees that any Holder or Holders
from time to time, with or without any further notice to or assent from any
other Guarantor may, without in any manner affecting the liability of any
Guarantor under this Guaranty, and upon such terms and conditions as any such
Holder or Holders may deem advisable:

          (1)  extend in whole or in part (by renewal or otherwise), modify,
     change, compromise, release or extend the duration of the time for the
     performance or payment of any Debt, liability or obligation of the Company
     or of any other Person secondarily or otherwise liable for any Debt,
     liability or obligations of the Company on the Notes, or waive any Default
     with respect thereto, or waive, modify, amend or change any provision of
     any other agreement or waive this Guaranty; or

          (2)  sell, release, surrender, modify, impair, exchange or substitute
     any and all property, of any nature and from whomsoever received, held by,
     or for the benefit of, any such Holder as direct or indirect security for
     the payment or performance of any Debt, liability or obligation of the
     Company or of any other Person secondarily or otherwise liable for any
     Debt, liability or obligation of the Company on the Notes; or

          (3)  settle, adjust or compromise any claim of the Company against any
     other Person secondarily or otherwise liable for any Debt, liability or
     obligation of the Company on the Notes.

     Each Guarantor hereby ratifies and confirms any such extension, renewal,
change, sale, release, waiver, surrender, exchange, modification, amendment,
impairment, substitution, settlement, adjustment or compromise and that the same
shall be binding upon it, and hereby waives, to the fullest extent permitted by
law, any and all defenses, counterclaims or offsets which it might or could have
by reason thereof, it being understood that such Guarantor shall at all times be
bound by this Guaranty and remain liable hereunder.

     (b)  Each Guarantor hereby waives, to the fullest extent permitted by law:

          (1)  notice of acceptance of this Guaranty by the Holders or of the
     creation, renewal or accrual of any liability of the Company, present or
     future, or of the 


                                      -3-
<PAGE>   6

     reliance of such Holders upon this Guaranty (it being understood that every
     Debt, liability and obligation described in Section 2 hereof shall
     conclusively be presumed to have been created, contracted or incurred in
     reliance upon the execution of this Guaranty);

          (2)  demand of payment by any Holder from the Company or any other
     Person indebted in any manner on or for any of the Debt, liabilities or
     obligations hereby guaranteed; and

          (3)  presentment for the payment by any Holder or any other Person of
     the Notes or any other instrument, protest thereof and notice of its
     dishonor to any party thereto and to such Guarantor.

     The obligations of each Guarantor under this Guaranty and the rights of any
Holder to enforce such obligations by any proceedings, whether by action at law,
suit in equity or otherwise, shall not be subject to any reduction, limitation,
impairment or termination, whether by reason of any claim of any character
whatsoever or otherwise and shall not be subject to any defense, set-off,
counterclaim (other than any compulsory counterclaim), recoupment or termination
whatsoever.

     (c)  The obligations of the Guarantors hereunder shall be binding upon the
Guarantors and their successors and assigns, and shall remain in full force and
effect irrespective of:

          (1)  the genuineness, validity, regularity or enforceability of the
     Notes, the Note Agreement or any other agreement or any of the terms of any
     thereof, the continuance of any obligation on the part of the Company or
     any other Person on or in respect of the Notes or under the Note Agreement
     or any other agreement or the power or authority or the lack of power or
     authority of the Company to issue the Notes or the Company to execute and
     deliver the Note Agreement or any other agreement or of any Guarantor to
     execute and deliver this Guaranty or to perform any of its obligations
     hereunder or the existence or continuance of the Company or any other
     Person as a legal entity; or

          (2)  any default, failure or delay, willful or otherwise, in the
     performance by the Company, any Guarantor or any other Person of any
     obligations of any kind or character whatsoever under the Notes, the Note
     Agreement, this Guaranty or any other agreement; or

          (3)  any creditors' rights, bankruptcy, receivership or other
     insolvency proceeding of the Company, any Guarantor or any other Person or
     in respect of the property of the Company, any Guarantor or any other
     Person or any merger, consolidation, reorganization, dissolution,
     liquidation, the sale of all or substantially all of the assets of or
     winding up of the Company, any Guarantor or any other Person; or

     Company, any Guarantor or any other Person of its obligations under the
     Notes, the Note Agreement, this Guaranty or any other agreements; or

     circumstances, whether or not foreseen or foreseeable, whether or not
     imputable to the Company or any other Person, or other impossibility of

     source, by reason of any taxes, assessments, expenses, Debt, obligations or

     unforeseen, incurred by the Company, any Guarantor or any other Person, or
     against any sums payable in respect of the Notes or under the Note
     Agreement or this Guaranty, so that such sums would be rendered inadequate

     advance of additional money to the Company or any other Person, the renewal
     or extension of the Notes or amendments, modifications, consents or waivers
     with respect to the Notes, the Note Agreement or any other agreement, or

          (12) any defense whatsoever that: (i) the Company or any other Person
     might have to the payment of the Notes (principal, premium, if any, or
     interest), other than payment thereof in Federal or other immediately
     available funds, or (ii) the Company or any other Person might have to the
     performance or observance of any of the provisions of the Notes, the Note
     Agreement or any other agreement, whether through the satisfaction or
     purported satisfaction by the Company or any other Person of its debts due
     to any cause such as bankruptcy, insolvency, receivership, merger,
     consolidation, reorganization, dissolution, liquidation, winding-up or
     otherwise; or

          (13) any act or failure to act with regard to the Notes, the Note
     Agreement, this Guaranty or any other agreement or anything which might
     vary the risk of any Guarantor or any other Person; or

          (14) any other circumstance which might otherwise constitute a defense
     available to, or a discharge of, any Guarantor or any other Person in
     respect of the obligations of any Guarantor or other Person under this
     Guaranty or any other agreement;

provided that the specific enumeration of the above-mentioned acts, failures or
omissions shall not be deemed to exclude any other acts, failures or omissions,
though not specifically mentioned above, it being the purpose and intent of this
Guaranty and the parties hereto that the obligations of each Guarantor shall be
absolute and unconditional and shall not be discharged, impaired or varied
except by the payment of the principal of, premium, if any, and interest on the
Notes in accordance with their respective terms whenever the same shall become
due and payable as in the Notes provided, at the place specified in and all in
the manner and with the effect provided in the Notes and the Note Agreement, as
each may be amended or modified from time to time. Without limiting the
foregoing, it is understood that repeated and successive demands may be made and
recoveries may be had hereunder as and when, from time to time, the Company
shall default under or in respect of the terms of the Notes or the Note
Agreement and that notwithstanding recovery hereunder for or in respect of any
given default or defaults by the Company under the Notes or the Note Agreement,
this Guaranty shall remain in full force and effect and shall apply to each and
every subsequent default.


                                      -6-
<PAGE>   9

     (d)  All rights of any Holder may be transferred or assigned at any time
and shall be considered to be transferred or assigned at any time or from time
to time upon the transfer of such Note whether with or without the consent of or
notice to the Guarantors under this Guaranty or to the Company.

     (e)  To the extent of any payments made under this Guaranty, the Guarantors
shall be subrogated to the rights of the Holder or Holders upon whose Notes such
payment was made, but each Guarantor covenants and agrees that such right of
subrogation shall be junior and subordinate in right of payment to the prior
indefeasible final payment in cash in full of all amounts due and owing by the
Company with respect to the Notes and the Note Agreement and by the Guarantors
under this Guaranty, and the Guarantors shall not take any action to enforce
such right of subrogation, and the Guarantors shall not accept any payment in
respect of such right of subrogation, until all amounts due and owing by the
Company under or in respect of the Notes and the Note Agreement and all amounts
due and owing by the Guarantors hereunder have indefeasibly been finally paid in
cash in full. If any amount shall be paid to any Guarantor in violation of the
preceding sentence at any time prior to the later of the indefeasible payment in
cash in full of the Notes and all other amounts payable under the Notes, the
Note Agreement and this Guaranty, such amount shall be held in trust for the
benefit of the Holders and shall forthwith be paid to the Holders to be credited
and applied to the amounts due or to become due with respect to the Notes and
all other amounts payable under the Note Agreement and this Guaranty, whether
matured or unmatured.

     (f)  Each Guarantor agrees that to the extent the Company or any other
Person makes any payment on any Note, which payment or any part thereof is
subsequently invalidated, voided, declared to be fraudulent or preferential, set
aside, recovered, rescinded or is required to be retained by or repaid to a
trustee, receiver, or any other Person under any bankruptcy code, common law, or
equitable cause, then and to the extent of such payment, the obligation or the
part thereof intended to be satisfied shall be revived and continued in full
force and effect with respect to the Guarantors' obligations hereunder, as if
said payment had not been made. The liability of the Guarantors hereunder shall
not be reduced or discharged, in whole or in part, by any payment to any Holder
from any source that is thereafter paid, returned or refunded in whole or in
part by reason of the assertion of a claim of any kind relating thereto,
including, but not limited to, any claim for breach of contract, breach of
warranty, preference, illegality, invalidity, or fraud asserted by any account
debtor or by any other Person.

     (g)  No Holder shall be under any obligation: (1) to marshall any assets in
favor of the Guarantors or in payment of any or all of the liabilities of the
Company under or in respect of the Notes or the obligations of the Guarantors
hereunder or (2) to pursue any other remedy that the Guarantors may or may not
be able to pursue themselves and that may lighten the Guarantors' burden, any
right to which each Guarantor hereby expressly waives.

SECTION 5.   REPRESENTATIONS AND WARRANTIES OF THE GUARANTORS.

     Each Guarantor represents and warrants to each Holder that:

     (a)  Such Guarantor is a corporation or other legal entity duly organized,
validly existing and in good standing under the laws of its jurisdiction of
organization, and is duly qualified as a foreign corporation or other legal
entity and is in good standing in each jurisdiction in which such qualification
is required by law, other than those jurisdictions as to which the failure to be
so qualified or in good standing could not, individually or in the aggregate,
reasonably be expected to have a material adverse effect on (1) the business,
operations, affairs, financial condition, assets, properties or prospects of
such Guarantor and its subsidiaries, taken as a whole, or (2) the ability of
such Guarantor to perform its obligations under this Guaranty, or (3) the
validity or enforceability of this Guaranty (herein in this Section 5, a
"Material Adverse Effect"). Such Guarantor has the power and authority to own or
hold under lease the properties it purports to own or hold under lease, to
transact the business it transacts and proposes to transact, to execute and
deliver this Guaranty and to perform the provisions hereof.

     (b)  Each subsidiary of such Guarantor is a corporation or other legal
entity duly organized, validly existing and in good standing under the laws of
its jurisdiction of organization, and is duly qualified as a foreign corporation
or other legal entity and is in good standing in each jurisdiction in which such
qualification is required by law, other than those jurisdictions as to which the
failure to be so qualified or in good standing could not, individually or in the
aggregate, reasonably be expected to have a Material Adverse Effect. Each
subsidiary of such Guarantor has the power and authority to own or hold under
lease the properties it purports to own or hold under lease and to transact the
business it transacts and proposes to transact.

     (c)  This Guaranty has been duly authorized by all necessary action on the
part of such Guarantor, and this Guaranty constitutes a legal, valid and binding
obligation of such Guarantor enforceable against such Guarantor in accordance
with its terms, except as such enforceability may be limited by (1) applicable
bankruptcy, insolvency, reorganization, moratorium or other similar laws
affecting the enforcement of creditors' rights generally and (2) general
principles of equity (regardless of whether such enforceability is considered in
a proceeding in equity or at law).

     (d)  This Guaranty, the documents, certificates or other writings
identified in Schedule 5.3 to the Note Agreement and the financial statements
listed in Schedule 5.5 to the Note Agreement, taken as a whole, do not contain
any untrue statement of a material fact or omit to state any material fact
necessary to make the statements therein not misleading in light of the
circumstances under which they were made. Except as disclosed in the Memorandum
or as expressly described in Schedule 5.3 to the Note Agreement, or in one of
the documents, certificates or other writings identified therein, or in the
financial statements listed in Schedule 5.5 to the Note Agreement, since
December 31, 1996, there has been no adverse Material change in the financial
condition, operations, business, properties or prospects of such Guarantor or
any of its subsidiaries, taken as a whole.

     (e)  The execution, delivery and performance by such Guarantor of this
Guaranty will not (1) contravene, result in any breach of, or constitute a
default under, or result in the creation of any Lien in respect of any property
of such Guarantor or any of its subsidiaries under any indenture, mortgage, deed
of trust, loan, purchase or credit agreement, lease, charter document or by-law,
or any other agreement or instrument to which such Guarantor or any of its
subsidiaries is bound or by which such Guarantor or any of its subsidiaries or
any of their respective properties may be bound or affected, (2) conflict with
or result in a breach of any of the terms, conditions or provisions of any
order, judgment, decree, or ruling of any court, arbitrator or Governmental
Authority applicable to such Guarantor or any of its subsidiaries or (3) violate
any provision of any statute or other rule or regulation of any Governmental
Authority applicable to the such Guarantor or any of its subsidiaries.

     (f)  No consent, approval or authorization of, or registration, filing or
declaration with, any Governmental Authority is required in connection with the
execution, delivery or performance by such Guarantor of this Guaranty.

     (g)  (1) Except as disclosed in Schedule 5.8 to the Note Agreement, there
are no actions, suits or proceedings pending or, to the knowledge of such
Guarantor, threatened against or affecting such Guarantor or any of its
subsidiaries or any property of such Guarantor or any of its subsidiaries in any
court or before any arbitrator of any kind or before or by any Governmental
Authority that, individually or in the aggregate, could reasonably be expected
to have a Material Adverse Effect.

          (2)  Neither such Guarantor nor any of its subsidiaries is in default
under any term of any agreement or instrument to which it is a party or by which
it is bound, or any order, judgment, decree or ruling of any court, arbitrator
or Governmental Authority or is in violation of any applicable law, ordinance,
Rule or regulation (including without limitation Environmental Laws) of any
Governmental Authority, which default or violation, individually or in the
aggregate, could reasonably be expected to have a Material Adverse Effect.

     (h)  Such Guarantor and its subsidiaries have filed all income tax returns
that are required to have been filed in any jurisdiction, and have paid all
taxes shown to be due and payable on such returns and all other taxes and
assessments payable by them, to the extent such taxes and assessments have
become due and payable and before they have become delinquent, except for any
taxes and assessments (1) the amount of which is not individually or in the
aggregate material to the business, operations, affairs, financial condition,
assets, properties or prospects of such Guarantor and its subsidiaries taken as
a whole (herein in this Section 5, "Material") or (2) the amount, applicability
or validity of which is currently being contested in good faith by appropriate
proceedings and with respect to which such Guarantor or one of its subsidiaries,
as the case may be, has established adequate reserves in accordance with GAAP.
Such Guarantor knows of no basis for any other tax or assessment that could
reasonably be expected to have a Material Adverse Effect. The charges, accruals
and reserves on the books of such Guarantor and its subsidiaries in respect of 
Federal, state or other taxes for all fiscal periods are adequate. The Federal 
income tax liabilities of such


                                      -9-
<PAGE>   12

Guarantor and its subsidiaries have been determined by the Internal Revenue
Service and paid for all fiscal years up to and including the fiscal year ended
December 31, 1992.

     (i)  Such Guarantor and its subsidiaries have good and sufficient title to
their respective properties that individually or in the aggregate are Material,
including all such properties reflected in the most recent audited balance sheet
referred to in Section 5.5 of the Note Agreement or purported to have been
acquired by such Guarantor or any of its subsidiaries after said date (except as
sold or otherwise disposed of in the ordinary course of business), in each case
free and clear of Liens prohibited by the Note Agreement. All leases that
individually or in the aggregate are Material are valid and subsisting and are
in full force and effect in all material respects.

     (j)  Except as disclosed in Schedule 5.11 to the Note Agreement,

          (1)  such Guarantor and its subsidiaries own or possess all Material
licenses, permits, franchises, authorizations, patents, copyrights, service
marks, trademarks and trade names, or rights thereto;

          (2)  to the best knowledge of such Guarantor, no product of such
Guarantor or any of its subsidiaries infringes in any material respect any
license, permit, franchise, authorization, patent, copyright, service mark,
trademark, trade name or other right with respect thereto owned by any other
Person; and

          (3)  to the best knowledge of such Guarantor, there is no Material
violation by any Person of any right of such Guarantor or any of its
subsidiaries with respect to any patent, copyright, service mark, trademark,
trade name or other right with respect thereto owned or used by such Guarantor
or any of its subsidiaries.

     (k)  (1) Such Guarantor and each ERISA Affiliate have operated and
administered each Plan in compliance with all applicable laws in all material
respects. Neither such Guarantor nor any ERISA Affiliate has incurred any
Material liability pursuant to Title I or IV of ERISA or the penalty or excise
tax provisions of the Code relating to employee benefit plans (as defined in
Section 3 of ERISA), and no event, transaction or condition has occurred or
exists that could reasonably be expected to result in the incurrence of any such
Material liability by such Guarantor or any ERISA Affiliate, or in the
imposition of any Material Lien on any of the rights, properties or assets of
such Guarantor or any ERISA Affiliate, in either case pursuant to Title I or IV
of ERISA or to such penalty or excise tax provisions or to Section 401(a)(29) or
412 of the Code.

          (2)  The present value of the aggregate benefit liabilities under each
of the Plans (other than Multiemployer Plans), determined as of the end of such
Plan's most recently ended plan year on the basis of the actuarial assumptions 
specified for funding purposes in such Plan's most recent actuarial valuation 
report, did not exceed the aggregate current value of the assets of such Plan 
allocable to such benefit liabilities by more than $5,000,000 in the aggregate 
for all Plans. The term "benefit liabilities" has the meaning 


                                      -10-
<PAGE>   13

specified in Section 4001 of ERISA and the terms "current value" and "present 
value" have the meanings specified in Section 3 of ERISA.

          (3)  Such Guarantor and its ERISA Affiliates have not incurred
Material withdrawal liabilities (and are not subject to Material contingent
withdrawal liabilities) under Section 4201 or 4204 of ERISA in respect of
Multiemployer Plans.

          (4)  The expected postretirement benefit obligation (determined as of
the last day of such Guarantor's most recently ended fiscal year in accordance
with Financial Accounting Standards Board Statement No. 106, without regard to
liabilities attributable to continuation coverage mandated by Section 4980B of
the Code) of such Guarantor and its subsidiaries is not Material.

          (5)  The execution and delivery of this Guaranty will not involve any
transaction that is subject to the prohibitions of Section 406 of ERISA or in
connection with which a tax could be imposed pursuant to Section
4975(c)(l)(A)-(D) of the Code. The representation by such Guarantor in the first
sentence of this Section 5(k)(5) is made in reliance upon and subject to the
accuracy of each Holder's representation in Section 6.2 of the Note Agreement as
to the source of the funds to be used to pay the purchase price of the Notes to
be purchased by such Holder.

     (l)  Neither such Guarantor nor any of its subsidiaries is an "investment
company" registered or required to be registered under the Investment Company
Act of 1940, as amended, or is subject to regulation under the Public Utility
Holding Company Act of 1935, as amended, the ICC Termination Act of 1995, as
amended, or the Federal Power Act, as amended.

     (m)  Neither such Guarantor nor any of its subsidiaries has knowledge of
any Material claim or has received any notice of any Material claim, and no
proceeding has been instituted raising any Material claim against such Guarantor
or any of its subsidiaries or any of their respective real properties now or
formerly owned, leased or operated by any of them or other assets, alleging any
damage to the environment or violation of any Environmental Laws. Except as
otherwise disclosed in Schedule 5.18 to the Note Agreement:

          (1)  neither such Guarantor nor any of its subsidiaries has knowledge
     of any facts which would give rise to any Material claim, public or
     private, or Material violation of Environmental Laws or damage to the
     environment emanating from, occurring on or in any way related to real
     properties now or formerly owned, leased or operated by any of them or to
     other assets or their use;

          (2)  neither the Company nor any of its subsidiaries (i) has stored
     any Hazardous Materials on real properties now or formerly owned, leased or
     operated by any of them or (ii) has disposed of any Hazardous Materials in
     a manner contrary to any Environmental Laws; in each case in any manner
     that could reasonably be expected to result in a Material Adverse Effect;
     and


                                      -11-
<PAGE>   14

          (3)  all buildings on all real properties now owned, leased or
     operated by such Guarantor or any of its subsidiaries are in material
     compliance with applicable Environmental Laws.

     (n)  Such Guarantor, when viewed on a consolidated basis with the Company
and its other Subsidiaries, is solvent, has capital not unreasonably small in
relation to its business or any contemplated or undertaken transaction and has
assets having a value both at fair valuation and at present fair salable value
greater than the amount required to pay its debts as they become due and greater
than the amount that will be required to pay its probable liability on its
existing debts as they become absolute and matured. Such Guarantor does not
intend to incur, or believe or should have believed that it will incur, debts
beyond its ability to pay such debts as they become due. Such Guarantor, when
viewed on a consolidated basis with the Company and its other Subsidiaries, will
not be rendered insolvent by the execution and delivery of, and performance of
its obligations under, this Guaranty. Such Guarantor does not intend to hinder,
delay or defraud its creditors by or through the execution and delivery of, or
performance of its obligations under, this Guaranty.

SECTION 6.   AMENDMENTS, WAIVERS AND CONSENTS.

     (a)  This Guaranty may be amended, and the observance of any term hereof
may be waived (either retroactively or prospectively), with (and only with) the
written consent of each Guarantor and the Required Holders, except that (1) no
amendment or waiver of any of the provisions of Sections 3, 4 or 5, or any
defined term (as it is used therein), will be effective as to any Holder unless
consented to by such Holder in writing, and (2) no such amendment or waiver may,
without the written consent of each Holder, (i) change the percentage of the
principal amount of the Notes the Holders of which are required to consent to
any such amendment or waiver, or (ii) amend Section 2 or this Section 6.

     (b)  The Guarantors will provide each Holder (irrespective of the amount of
Notes then owned by it) with sufficient information, sufficiently far in advance
of the date a decision is required, to enable such Holder to make an informed
and considered decision with respect to any proposed amendment, waiver or
consent in respect of any of the provisions hereof. The Guarantors will deliver
executed or true and correct copies of each amendment, waiver or consent
effected pursuant to the provisions of this Section 6 to each Holder promptly
following the date on which it is executed and delivered by, or receives the
consent or approval of, the requisite Holders.

     (c)  The Company will not directly or indirectly pay or cause to be paid
any remuneration, whether by way of fee or otherwise, or grant any security, to
any Holder as consideration for or as an inducement to the entering into by any
Holder of any waiver or amendment of any of the terms and provisions hereof
unless such remuneration is concurrently paid, or security is concurrently
granted, on the same terms, ratably to each Holder even if such Holder did not
consent to such waiver or amendment.

     (d)  Any amendment or waiver consented to as provided in this Section 6
applies equally to all Holders and is binding upon them and upon each future
holder and upon the 


                                      -12-
<PAGE>   15

Guarantors. No such amendment or waiver will extend to or affect any obligation,
covenant or agreement not expressly amended or waived or impair any right
consequent thereon. No course of dealing between the Guarantors and any Holder
nor any delay in exercising any rights hereunder shall operate as a waiver of
any rights of any Holder. As used herein, the term "this Guaranty" and
references thereto shall mean this Guaranty as it may from time to time be
amended or supplemented.

     (e)  Solely for the purpose of determining whether the Holders of the
requisite percentage of the aggregate principal amount of Notes then outstanding
approved or consented to any amendment, waiver or consent to be given under this
Guaranty, Notes directly or indirectly owned by any Guarantor, the Company or
any of their respective subsidiaries or Affiliates shall be deemed not to be
outstanding.

SECTION 7.   NOTICES.

     All notices and communications provided for hereunder shall be in writing
and sent (a) by telefacsimile if the sender on the same day sends a confirming
copy of such notice by a recognized overnight delivery service (charges
prepaid), or (b) by registered or certified mail with return receipt requested
(postage prepaid), or (c) by a recognized overnight delivery service (with
charges prepaid). Any such notice must be sent:

          (1)  if to an Initial Note Purchaser or such Initial Note Purchaser's
     nominee, to such Initial Note Purchaser or such Initial Note Purchaser's
     nominee at the address specified for such communications below such Initial
     Note Purchaser's signature at the foot of the Note Agreement, or at such
     other address as such Initial Note Purchaser or such Initial Note
     Purchaser's nominee shall have specified to any Guarantor or the Company in
     writing,

          (2)  if to any other Holder, to such Holder at such address as such
     Holder shall have specified to any Guarantor or the Company in writing, or

          (3)  if to any Guarantor, to such Guarantor c/o the Company at its
     address set forth at the beginning of the Note Agreement to the attention
     of Chief Financial Officer, or at such other address as such Guarantor
     shall have specified to the Holders in writing.

Notices under this Section 7 will be deemed given only when actually received.

SECTION 8.   MISCELLANEOUS.

     (a)  No remedy herein conferred upon or reserved to any Holder is intended
to be exclusive of any other available remedy or remedies, but each and every
such remedy shall be cumulative and shall be in addition to every other remedy
given under this Guaranty now or hereafter existing at law or in equity. No
delay or omission to exercise any right or power accruing upon any default,
omission or failure of performance hereunder shall 


                                      -13-
<PAGE>   16

impair any such right or power or shall be construed to be a waiver thereof but
any such right or power may be exercised from time to time and as often as may
be deemed expedient. In order to entitle any Holder to exercise any remedy
reserved to it under the Guaranty, it shall not be necessary for such Holder to
physically produce its Note in any proceedings instituted by it or to give any
notice, other than such notice as may be herein expressly required.

     (b)  The Guarantors will pay all sums becoming due under this Guaranty by
the method and at the address specified for such purpose below each Holder's
signature at the foot of the Note Agreement, or by such other method or at such
other address as any Holder shall have from time to time specified to the
Guarantors in writing for such purpose, without the presentation or surrender of
this Guaranty or any Note.

     (c)  Any provision of this Guaranty that is prohibited or unenforceable in
any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of
such prohibition or unenforceability without invalidating the remaining
provisions hereof, and any such prohibition or unenforceability in any
jurisdiction shall (to the full extent permitted by law) not invalidate or
render unenforceable such provision in any other jurisdiction.

     (d)  If the whole or any part of this Guaranty shall be now or hereafter
become unenforceable against any one or more of the Guarantors for any reason
whatsoever or if it is not executed by any one or more of the Guarantors, this
Guaranty shall nevertheless be and remain fully binding upon and enforceable
against each other Guarantor as if it had been made and delivered only by such
other Guarantors.

     (e)  This Guaranty shall be binding upon each Guarantor and its successors
and assigns and shall inure to the benefit of each Holder and its successors and
assigns so long as its Notes remain outstanding and unpaid.

     (f)  This Guaranty may be executed in any number of counterparts, each of
which shall be an original but all of which together shall constitute one
instrument. Each counterpart may consist of a number of copies hereof, each
signed by less than all, but together signed by all, of the parties hereto.

     (g)  This Guaranty shall be construed and enforced in accordance with, and
the rights of the parties shall be governed by, the law of the State of Illinois
excluding choice-of-law principles of the law of such State that would require
the application of the laws of a jurisdiction other than such State.
