ITEM 1.    BUSINESS

      This report contains forward-looking statements within the meaning of
Section 27A of the Securities Act of 1933 and Section   21E of the Securities
Exchange Act of 1934. Actual results could differ materially from those
projected in the forward-looking statements as a result of the changes in the
composition of applicable federal and state legislation appropriation
committees; federal and state appropriation changes for infrastructure spending;
the general state of the economy; competition and pricing pressures; state
referendums and initiatives; and other risks detailed from time to time in the
Company's filings with the Securities and Exchange Commission.

INTRODUCTION

      Granite Construction Incorporated, the "Company", is one of the largest
heavy civil construction contractors and is the largest transportation
contractor in the United States as ranked by Engineering News-Record magazine,
May 1997. Granite operates throughout the United States, focusing primarily in
the west, southwest and southeast and serves 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.

      Granite also owns and leases substantial aggregate reserves and owns 108
construction materials processing plants and 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.

      Granite Construction Incorporated was incorporated in Delaware in January
1990 as the holding company for Granite Construction Company, which was
incorporated in California in 1922. Granite operates primarily through its
wholly owned subsidiary, Granite Construction Company and has ten less
significant wholly-owned subsidiaries.

RECENT DEVELOPMENT

      During 1997, the Company completed the purchase of a 30% minority interest
in T.I.C. Holdings Inc. ("TIC") as part of its diversification strategy (See
Business Strategy). The transaction included a 10% ownership interest acquired
in 1996.

      TIC, founded in 1974, is one of the leading merit shop, general heavy
industrial contractors in the U.S., and is ranked in the Top 20 in both the
industrial and power marketplaces by Engineering News-Record Magazine. 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 revenues
of $420.5 million in 1997. By market sector, 57% of its 1997 revenue came from
industrial/petrochemical projects, 24% from water/sewer/wastewater projects, 12%
from power-related projects, and the remaining 7% derived from
transportation-related and other work.

OPERATING STRUCTURE

      The principal operating company, Granite Construction Company, is
organized into two operating divisions. 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 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.

      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


                                       3
<PAGE>   4
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 which
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.

      The Branch Division. In 1997, Branch Division contract revenue and sales
of aggregate products were $831.9 million (81% of Company revenue) as compared
with $715.6 million (77% of Company revenue) in 1996. 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 13 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 1997 these revenues ranged
from $33 million to $158 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. More than half of the aggregate products are used in the Company's
construction projects. The remainder is sold to unaffiliated parties and
accounted for $127.1 million of revenue in 1997, representing 12.4% of the
Company's total 1997 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 1997, revenue from HCD was $196.3 million
(19% of Company revenue) as compared with $213.2 million (23% of Company
revenue) in 1996. 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.


      The Division markets, estimates, bids and provides management overview of
its projects from its Watsonville headquarters and satellite estimating offices
in Texas, Georgia, Florida and Maryland. Project staffs located at job sites
have the managerial, technical, and clerical capacity to meet on-site project
management requirements. HCD


                                       4
<PAGE>   5
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 where it is desirable to share risk and resources. Joint ventures
provide independently prepared estimates, and shared financing, equipment and
expertise.

      Privatization as a new market sector for the Division emerged in 1995 as
the Company pioneered the use of public/private partnerships to fund the
construction of public infrastructure projects which are not supported by
traditional tax-based revenue sources. Two such projects have been successfully
completed in joint venture - in 1995, the SR91 congestion relieving toll lanes
project and, in 1996, the San Joaquin Hills Transportation Corridor. As an
investor in the SR91 project, the Company participates in the partnership that
will operate the toll road under a 35 year franchise agreement with the State of
California. Except for these initial significant successes, the pursuit by HCD
of additional contracts in this market has been frustrated by a public sector
which is not yet ready to mix public and private sources of financing to produce
needed transportation facilities. Granite has turned its attention to private
sector projects where there appears to be potential to develop, design and
build.

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 a minor 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: 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 by ensuring availability
      of these resources at favorable cost believes it has significant bidding
      advantages in many of its markets.

      Selective Bidding - Once Granite selects a job that meets our 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.

      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 effectively operates
      an internal leasing company, competing 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, by
      pursuing major infrastructure projects throughout the nation and expanding
      into other construction market segments through acquisitions.



                                       5
<PAGE>   6
      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 all parties 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.

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, Arizona, Nevada and Utah. In 1997, contracts with the California
Department of Transportation represented 13.5% 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, the State Departments of
Highways and Public Transportation in Texas, Georgia, Utah, Florida and New
Jersey, and the Metropolitan Water District of Southern California (See Note 2
of Notes to Consolidated Financial Statements).

      A breakdown of the Company's revenues for the last three years by market
sector is as follows (in thousands):

BACKLOG

      The Company's backlog (anticipated revenue from uncompleted portions of
existing contracts) was $909.8 million at December 31, 1997, up from $597.9
million at December 31, 1996. The Company's backlog was $590.1 million at the
end of 1995. Approximately $380 million of the December 31, 1997 backlog will
remain at December 31, 1998. 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 substantial 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, 1997(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 1997 and 1996, the Company spent
approximately $45.4 million and $43.0 million, respectively, for construction
equipment, plants and vehicles. The breakdown of the Company's construction
equipment, plants and vehicles at December 31, 1997 is as follows:

<TABLE>
<S>                                                                          <C>
      Heavy construction equipment.....................................      2,207  units
      Trucks, truck-tractors and trailers and vehicles.................      2,876  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, 1997, Granite employed 1,054 salaried employees, who work
in management, estimating and clerical capacities, and 2,446 hourly employees.
The total number of hourly personnel employed by the Company is subject to the
volume of construction in progress. During 1997, the number of hourly employees
ranged from 1,803 to 4,052 and averaged approximately 3,309. The 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 feeling of dedication to and pride in the
Company. Among salaried and non-union hourly employees, this dedication is
reinforced by 30% equity ownership through the Employee Stock Ownership Plan
("ESOP") and performance-based incentive compensation arrangements. The
Company's 367 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 generally requires its
subcontractors to furnish bonds guaranteeing their performance. Affirmative
action regulations require the Company to use its best efforts to employ certain
types of subcontractors for a specified portion (historically ranging up to 25%)
of contract work done for governmental agencies. 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 guaranteeing 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 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
355,600 square feet of office and shop space and leases, pursuant to leases
expiring in the year 2000, an additional 55,600 square feet of office and shop
space. The Company owns approximately 10,200 acres of land of which 1,300 acres
are un-permitted reserves available for future use and leases approximately
4,500 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 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 1998
to January 2038. 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, 1997.

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

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

         The following "Management's Discussion and Analysis of Financial
Condition and Results of Operations" section contains forward-looking statements
which are made in reliance on the safe harbor provisions of the Private
Securities Litigation Reform Act of 1995. Investors are cautioned that such
forward-looking statements involve risks and uncertainties, including, without
limitation, changes in the composition of applicable federal and state
legislation appropriation committees; federal and state appropriation changes
for infrastructure spending; the general state of the economy; competition and
pricing pressures; state referendums and initiatives; and other risks detailed
from time to time in the Company's filings with the Securities and Exchange
Commission.

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, 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.


         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. Backlog at December 31,
1997 includes 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 $320


                                       13
<PAGE>   14
million portion of the contract began during the second quarter of 1997 with 25%
completion for profit recognition not expected until mid 1998. Management
expects that approximately 58% of the work in the backlog at December 31, 1997
will be recognized as revenue during 1998. The Company believes its bidding
opportunities in its major marketplaces remain strong (see "Outlook").

         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 reflects 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 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 $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.

         OTHER INCOME (EXPENSES). Other income increased $1.7 million to $6.0
million in 1997. The increase was due 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.

         NEW ACCOUNTING PRONOUNCEMENTS. In June 1997 the Financial Accounting
Standards Board ("FASB") issued Statement of Financial Accounting Standards No.
130 ("SFAS 130"), "Reporting Comprehensive Income." SFAS 130 establishes
standards for the reporting and display of comprehensive income and its
components in a full set of general purpose financial statements. Comprehensive
income is defined as the change in equity of a business enterprise during a
period from transactions and other events and circumstances from nonowner
sources. SFAS 130 is effective for the Company in 1998 and its impact on
adoption is not expected to be significant.

         In June 1997 the FASB issued Statement of Financial Accounting
Standards No. 131 ("SFAS 131"), "Disclosures about Segments of an Enterprise and
Related Information." SFAS 131 requires publicly-held companies to report
financial and other information about key revenue-producing segments of the
entity for which such information is available and is utilized by the chief
operations decision maker. Specific information to be reported for individual
segments includes profit or loss, certain revenue and expense items and total
assets. A reconciliation of segment financial information to amounts reported in
the financial statements would be provided. SFAS 131 is effective for the
Company in 1998 and the impact of adoption has not been determined.

         OUTLOOK. This "Outlook" section contains forward-looking statements
which are made in reliance on the safe harbor provisions of the Private
Securities Litigation Reform Act of 1995. Investors are cautioned that such
forward-looking statements involve risks and uncertainties, including, without
limitation, changes in the composition of applicable federal and state
legislation appropriation committees; federal and state appropriation changes
for infrastructure spending; the general state of the economy; competition and
pricing pressures; state referendums and initiatives; and other risks detailed
from time to time in the Company's filings with the Securities and Exchange
Commission.

         Looking ahead, re-authorization of the federal transportation bill,
often referred to as the "ISTEA" bill, is one of the most important issues
facing Granite and its industry in 1998. Federal funding for needed repair and
improvement of the nation's highway system expires May 1, 1998. If Congress
fails to take action by then, new federal funding for roads, bridges and transit
programs will cease. Some states, such as California, are currently enjoying the
fruits of a healthy state economy, and have surplus highway building funds that
could potentially be used to bridge any gap created by the lack of a federal
program, at least for the next fiscal year. In most states, however, that is not
the case, and the absence of federal highway funding could jeopardize many state
highway projects in the short-term.

                  We are very encouraged, however, by the action taken most
recently by the U.S. Senate. In previous communications with our shareholders,
we had indicated that it appeared unlikely that any action on the highway bill
would occur before the federal budget had been approved. Surprisingly, the
Senate passed a six-year, $214 billion ISTEA re-authorization bill in March
1998, a 38% increase over the previous authorization. The leadership in the
House has indicated that a companion bill will reach the floor by April 1. The
House version calls for increases in funding to $217 billion and taking the
Highway Trust Funds off-budget. A vote on the increase is expected to take place
during the week of March 30,


                                       14
<PAGE>   15
1998. Taking the trust funds off-budget provides a mechanism to ensure that the
authorized funding is actually spent. In previous years Congress didn't always
appropriate funds to the same level as authorized under the earlier ISTEA. If
the House could pass its bill by April 1, it would greatly increase the chances
of a final bill being passed and signed by President Clinton near the May 1
deadline.

                  At the state level, our attention remains focused on the June
primary election and Proposition 224, the so-called contracting-out initiative.
The measure seeks to codify and expand a legal decision that precludes the
California Department of Transportation from contracting out to private
companies for design services at times when the agency does not have the
capacity internally to design highway projects. If this initiative passes, it
would decrease the throughput in the design process and offer contractors like
Granite fewer projects on which to bid.

                  We are pleased by the recent upswing in the private sector,
especially in California. According to the Construction Industry Research Board
(CIRB) private nonresidential building was the strongest construction sector in
1997. Moreover, residential building, as measured by new units in building
permits, was up 27.2% at year-end compared to the totals at December, 1996.
Another indicator of economic strength is job growth, and according to the CIRB,
non-farm job growth increased an estimated 3.3% in 1997, up from a 2.2% increase
in 1996.

                  Despite a still growing economy and the limited number of
construction workers, the labor market has been stable and labor costs have not
accelerated. We continue to expand our training and development efforts across
the country to attract and retain talented employees at both engineer and craft
levels.

                  We were very pleased with the 1997 return on our investment in
TIC Holdings, Inc.. The company had a very good year, and it enters 1998 with a
strong backlog and some excellent bidding opportunities. We were successful in
teaming with TIC and its subsidiary, Western Summit, on a large sewage treatment
plant in Atlanta and we continue to look for ways in which our two companies can
pursue joint venture opportunities.

                  The size and the quality of the backlog that we take into 1998
provide Granite with the opportunity to achieve continued success in the coming
year. We have some excellent bidding prospects this year to add to that backlog,
including the $1.8 billion Alameda Corridor Project in Southern California,
several large highway projects in the Southeastern U.S., and the San Francisco
Bay Area bridge retrofit projects. We are pleased with the progress of the
Interstate 15 project that we are building in joint venture in Salt Lake City,
Utah. The project is somewhat ahead of schedule, and we now expect it will reach
the 25% completion threshold, at which Granite recognizes earnings on a job, in
the third, perhaps even the second quarter of 1998, instead of the fourth
quarter, as previously estimated.

                  Based on strong economics in most of the regions in which it
operates, our Branch Division, coming off the best year in its history, is
expecting more of the same in 1998. The division is off to a good start, due
largely to the boost it is getting from El Nino-related emergency storm repair
projects.

                  In summary, we enter 1998 with a record backlog and have a
number of exciting bidding opportunities in front of us. We still have to
execute the work, but based on the strength of our backlog, increased public
works expenditures, and the emergence of the private sector, we feel very
confident that we can continue to grow our revenue and our earnings at the pace
we expect of ourselves and which our investors and other stakeholders have come
to expect.

PRIOR YEARS

                  REVENUE AND BACKLOG. 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 Branch Division revenue increased $39.6 million to
$715.6 million in 1996, from $676.0 million in 1995. Heavy Construction Division
revenue decreased $5.6 million to $213.2 million in 1996, from $218.8 million in
1995. The Company's revenue from private sector contracts increased $49.1
million to $178.1 million, and went from 14.4% of total revenue in 1995 to 19.2%
of total revenue in 1996. Revenue from public sector contracts decreased to
$657.2 million, or 70.7% of the Company's revenue in 1996, from $674.7 million,
or 75.4% in 1995.

                  During the year ended December 31, 1995, revenue increased
$201.4 million (29.0%) to $894.8 million. The increase in revenue reflected a
strong quality backlog, healthy Turn Business and the addition of the Company's
new branch in Utah.

                  The Company's backlog at December 31, 1996 was $597.9 million,
up $7.8 million, or 1.3% over the same period in 1995.



                                       15
<PAGE>   16
         GROSS PROFIT. For the year ended December 31, 1996, gross profit
reached $110.7 million, a $1.3 million decrease from 1995. As a percentage of
revenue, gross profit decreased in 1996 to 11.9% from 12.5% in 1995. Gross
profit as a percentage of revenue in 1995 decreased to 12.5% from 13.0% in 1994.

         GENERAL AND ADMINISTRATIVE EXPENSES. General and administrative
expenses increased from $69.6 million, or 7.8% of revenue in 1995, to $71.6
million, or 7.7% of revenue in 1996. The increase reflects a full year of Utah
Branch activity as well as an approximately $3.0 million increase to bad debt
expense relating to one project. General and administrative expenses increased
$8.8 million from 1994 primarily due to the addition of the Utah Branch and
higher incentive compensation and retirement plan contributions.

         OTHER INCOME (EXPENSES). Other income increased $1.4 million to $4.3
million in 1996. The increase was influenced by $2.0 million of gain on sales of
joint venture owned equipment which cannot be expected to be repeated in future
years. Other income decreased $0.3 million to $3.0 million in 1995.

         During 1997, cash provided from operations of $63.8 million was
primarily used to purchase $48.4 million of property and equipment, to repay
$16.5 million of long-term debt, to pay dividends of $6.6 million and repurchase
$3.1 million of common stock. Changes in cash provided by operating activities
primarily reflect 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, plants
and equipment increased $2.3 million from 1996 to 1997 and $10.1 million from
1995 to 1996. The increase in 1996 primarily reflected the Company's purchase of
the Utah Branch in 1995.

         During 1997, the Company increased its investment in T.I.C. Holdings,
Inc. by $12.2 million to approximately 30% from the 10% investment in 1996. The
investment was financed by borrowings under the Company's revolving line of
credit.

         In March of 1997, the Board of Directors authorized the Company to
repurchase at management's discretion up to 500,000 shares of its own common
stock on the open market. Future purchases are expected to be made using the
Company's own cash resources. Shares repurchased will be held in the corporate
treasury and will be used to cover contributions to the current Employee Stock
Ownership Plan or for other corporate purposes.


         The Company has budgeted $66.0 million for capital expenditures in
1998, 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 $32.4 million was available at December 31, 1997.

         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


                                       16
<PAGE>   17
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.

         Based on a recent assessment, the Company determined that it will not
be required to materially modify or replace its software in response to the Year
2000 Issue. The Company has begun communications with 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 Issue. 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 does not believe that the cost of addressing the impact on
its computer systems of the Year 2000 Issue will be material to its business,
results of operations, financial condition, liquidity or capital resources.

         SUBSEQUENT EVENTS. On January 23, 1998, the Board of Directors declared
a special dividend of $0.12 per share of common stock in addition to a $0.075
per share quarterly dividend, payable on April 17, 1998 to stockholders of
record as of March 31, 1998. The quarterly dividend represents a $0.015 per
share increase over the quarterly dividends paid in 1997 of $0.06 per share.

         On March 19, 1998 the Company issued long-term debt 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.
Proceeds of the notes will be used to retire a portion of existing debt and for
general corporate purposes.

                         INDEPENDENT ACCOUNTANTS' REPORT

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

                  We have audited the accompanying consolidated balance sheets
         of Granite Construction Incorporated and Subsidiaries as of December
         31, 1997 and 1996, and the related consolidated statements of income,
         stockholders' equity and cash flows for each of the three years in the
         period ended December 31, 1997. 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 in accordance with generally accepted
         auditing standards. Those standards require that we plan and perform
         the audits 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. An audit also includes
         assessing the accounting principles used and significant estimates made
         by management, as well as evaluating the overall financial statement
         presentation. We believe that our audits provide a reasonable basis for
         our opinion.

                  In our opinion, the financial statements referred to above
         present fairly, in all material respects, the consolidated financial
         position of Granite Construction Incorporated and Subsidiaries as of
         December 31, 1997 and 1996, and the consolidated results of their
         operations and their cash flows for each of the three years in the
         period ended December 31, 1997 in conformity with generally accepted
         accounting principles.

                 NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

                      (IN THOUSANDS, EXCEPT 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 market 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 market interest rates 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.

                 NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
                      (IN THOUSANDS, EXCEPT PER SHARE DATA)


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
         and 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: The Company has adopted the
         provisions of Statement of Financial Accounting Standards No. 128,
         "Earnings Per Share" ("SFAS 128"), effective December 31, 1997. SFAS
         128 requires the presentation of basic and diluted 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 and upon the vesting of restricted common
         stock. All prior period earnings per share amounts have been restated
         to reflect the adoption of SFAS 128.

                  RECLASSIFICATIONS: Certain financial statement items have been
         reclassified to conform to the current year's format.

                  NEW ACCOUNTING PRONOUNCEMENTS: In June 1997 the Financial
         Accounting Standards Board ("FASB") issued Statement of Financial
         Accounting Standards No. 130 ("SFAS 130"), "Reporting Comprehensive
         Income". SFAS 130 establishes standards for the reporting and display
         of comprehensive income and its components in a full set of general
         purpose financial statements. Comprehensive income is defined as the
         change in equity of a business enterprise during a period from
         transactions and other events and circumstances from nonowner sources.
         SFAS 130 is effective for the Company in 1998 and the impact of its
         adoption is not expected to be significant.

                  In June 1997 the FASB issued Statement of Financial Accounting
         Standards No. 131 ("SFAS 131"), "Disclosures about Segments of an
         Enterprise and Related Information". SFAS 131 requires publicly-held
         companies to report financial and other information about key
         revenue-producing segments of the entity for which such information is
         available and is utilized by the chief operations decision maker.
         Specific information to be reported for individual segments includes
         profit or loss, certain revenue and expense items and total assets. A
         reconciliation of segment financial information to amounts reported in
         the financial statements would be provided. SFAS 131 is effective for
         the Company in 1998 and the impact of adoption has not been determined.

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.

         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 twelve financial
         institutions. The Company invests with high credit quality financial
         institutions, and, by policy, limits the amount of credit exposure to
         any financial institution. Substantially all of the Company's labor
         force is subject to collective bargaining agreements. Collective
         bargaining agreements covering 27.5% of the Company's unionized labor
         force at December 31, 1997 will expire during 1998.

                  The Company operates in a single industry segment encompassing
         the construction of infrastructure assets and has no foreign
         operations. Revenue received from federal, state and local government
         agencies amounted to $726,657 (70.6%) in 1997, $657,247 (70.7%) in
         1996, and $674,640 (75.4%) in 1995. One customer, California Department
         of Transportation, represented $139,300 (13.5%) in 1997, $104,171
         (11.2%) in 1996, and $88,970 (9.9%) in 1995 of total revenue. At
         December 31, 1997, 1996 and 1995 the Company had significant amounts
         receivable from these agencies and customer. 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.

8.       LONG-TERM DEBT AND CREDIT ARRANGEMENTS, CONTINUED

                  Restrictive covenants under the terms of the 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 $188,000.

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

9.       EMPLOYEE BENEFIT AND COMPENSATION 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, 1997, the ESOP owned
         5,530,686 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, 1997, 1996
         and 1995 were approximately $1,812, $2,094 and $762, respectively.

                  PROFIT SHARING AND 401K PLAN: The Profit Sharing Plan is a
         defined contribution plan covering all employees not included in
         collective bargaining agreements. The plan receives annual
         contributions at the discretion of the Board of Directors. On January
         1, 1995, the Company amended the Profit Sharing Plan to create the
         Granite Construction Profit Sharing and 401K Plan, beginning for the
         year ended December 31, 1995. The amended plan is also a defined
         contribution plan covering all employees not included in collective
         bargaining agreements. Each employee can elect to have up to 3% 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, 1997, 1996 and 1995 were $4,706, $4,064 and
         $5,681, respectively. Included in the contributions were 401K matching
         contributions of $1,807, $1,647 and none in 1997, 1996 and 1995,
         respectively.

                  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.

                  Restricted shares outstanding under the Plan at December 31,
         1997 were 651,546 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, 1997,
         1996 and 1995 was $2,299, $1,968 and $1,549, respectively.

         options granted under the Stock Plan may not be less than 100% and 85%,
         respectively, of the fair market value at the date of the grant.
         Options granted will be exercisable at such times and be subject to

         committee, but no option shall be exercisable later than ten years from

                     (iii) Distribute all or a portion of the 401(k)
           Contributions made on behalf of a Highly Compensated Employee
           (together with any income attributable thereto) to him which are
           determined to be "excess contributions" within the meaning of Section
           1.40l(k)-1(g)(7) of the regulations. Such "excess contributions" are
           determined by reducing 401(k) Contributions made on behalf of Highly
           Compensated Employees in order of the actual deferral percentages
           beginning with the highest of such percentages. The actual deferral

           Compensated Employee with the next highest percentage. This process
           shall be repeated until one of the tests described in Section
           401(k)(3) of the Code and Section 1.401(k)-1(b) is passed. The amount
           of excess contributions to be distributed to Highly Compensated
           Employees under this Section 4(b)(3)(iii) shall be deemed
           attributable first to those Highly Compensated Employees who have the
           greatest dollar amount of 401(k) Contributions. Such excess
           contributions shall be reduced by any excess deferrals previously
           distributed under Section 4(b)(4) for the calendar year ending with
           the Plan Year.

           10. Section 4(c)(2) is amended by deleting the second sentence in the

           immediately following such birth or placement.

           13. Section 12(c) is restated to read as follows, effective as of

           shall occur not later than 60 days after the Allocation Date

           his Capital Accumulation shall occur 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.

           14. Section 15 is amended by adding the following sentence at the end

                                            percentage is the highest for that
                                            Plan Year. 401(k) Contributions made
                                            by key employees during a Plan Year
                                            shall be included in determining the
                                            "key employee" with the highest
                                            percentage for such Plan Year.

           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.

           12.        Section 12(b)(l) is amended by restating the first
sentence thereof, effective as of January 1, 1998:

           If the value of a Participant's Capital Accumulation is $5,000 or

           practicable after the date his Service terminates, upon the
           completion and processing of the applicable distribution forms.

           13.        Section 12(b)(2) is restated to read as follows, effective
as of January 1, 1998:

                      (2) If the value of a Participant's Capital Accumulation
           exceeds $5,000 and the Participant terminates Service (whether or not
           on account of Retirement or Disability), the Participant may elect to
           receive a distribution of his Capital Accumulation as soon as
           practicable after the date his Service terminates, upon the
           completion and processing of the applicable distribution forms.

           14.        Section 12(c) is restated to read as follows, effective as

                      (c) Distribution of a Participant's Capital Accumulation
           shall occur not later than 60 days after the Allocation Date
           coinciding with or next following his 65th birthday (or his
           termination of Service, if later). 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 lst of the next calendar year and must be made in
           accordance with the regulations under Section 40l(a)(9) of the Code,
           including Section 1.40l(a)(9)-2.

           Distributions must be made to any other Participant who attains age
           70 1/2 before January 1, 1999, only 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 occur 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.

           To record the adoption of this Amendment No. 5 to the amended and
restated Plan, Granite has caused it to be executed this 29th day of December ,

loan to the Company (each such loan, a "Term Loan") on the Closing Date in an
amount equal to the amount set forth opposite such Bank's name in Schedule

reduced pursuant to Section 2.05 or as a result of one or more assignments
pursuant to Section 11.07, the Bank's "Term Commitment"). Amounts borrowed as
Term Loans which are repaid or prepaid by the Company may not be reborrowed.

            (b)   The Revolving Credit. Each Bank severally agrees, on the terms
and conditions hereinafter set forth, to make Loans to the Company (each such
Loan, a "Revolving Loan") from time to time on any Business Day during the
period from the Closing Date to the Revolving Termination Date, in an aggregate
amount not to exceed at any time outstanding the amount set forth opposite the
Bank's name in Schedule 2.01(b) under the heading "Revolving Commitment" (such
amount as the same may be reduced pursuant to Section 2.05 or as a result of one
or more assignments pursuant to Section 11.07, the Bank's "Revolving
Commitment"); provided, however, that, after giving effect to any Borrowing of
Revolving Loans, the Effective Amount of all Revolving Loans and L/C Obligations
together shall not at any time exceed the Aggregate Revolving Commitment; and
provided further, that the sum of (i) the Effective Amount of the Revolving
Loans of any Bank, plus (ii) the participation of such Bank in the Effective
Amount of all L/C Obligations, shall not at any time exceed such Bank's
Revolving Commitment. Within the limits of each Bank's Revolving Commitment, and
subject to the other terms and conditions hereof, the Company may borrow under
this subsection 2.01(b), prepay pursuant to Section 2.06 and reborrow pursuant
to this subsection 2.01(b).

            (c)   Funding of Term Loans. Each Bank's obligation to fund its Term
Loan on the Closing Date shall be satisfied by deeming that each Bank's term
loan outstanding as of the Closing Date under the Prior Credit Agreement, which
loans aggregate $30,000,000 in principal amount, (the "Existing Term Loans")
shall be deemed to be its Term Loan hereunder.

Rate" in effect under and as defined in the Prior Credit Agreement with respect
to such loans (plus the Applicable Margin hereunder).

or more loan accounts maintained by such Bank in the ordinary course of
business. The loan accounts maintained by the Agent and each Bank shall be
rebuttable presumptive evidence of the amount of the Loans made by the Banks to
the Company and the interest and payments thereon. Any failure so to record or
any error in doing so shall not, however, limit or otherwise affect the
obligation of the Company hereunder to pay any amount owing with respect to the
Loans.

                        (C)   whether the Borrowing is to be comprised of
            Eurodollar Rate Loans, CD Rate Loans or Reference Rate Loans; and

                        (D)   with respect to Eurodollar Rate Loans and CD Rate
            Loans, the duration of the Interest Period applicable to such Loans
            included in such notice. If the Notice of Borrowing shall fail to
            specify the duration of the Interest Period for any Borrowing
            comprised of CD Rate Loans or Eurodollar Rate Loans, such Interest
            Period shall be 90 days or three months, respectively.

            (b)   Upon receipt of the Notice of Borrowing, the Agent will
promptly notify each Bank thereof of the amount of such Bank's Commitment
Percentage of the Borrowing.

            (c)   Each Bank will make the amount of its Commitment Percentage of
the Borrowing available to the Agent for the account of the Company at the
office specified by the Agent in Section 11.02 for payment by 10:00 a.m. (San
Francisco time), in the case of CD Rate Loans or Eurodollar Rate Loans, or 12:00
noon (San Francisco time), in the case of Reference Rate Loans, in each case on
the borrowing date requested by the Company in funds immediately available to
the Agent. Unless any applicable condition specified in Article V has not been
satisfied, the proceeds of all such Loans will then be made available to the
Company by the Agent at such office by crediting the account of the Company on
the books of BofA with the aggregate of the amounts made available to the Agent
by the Banks and in like funds as received by the Agent.

            (d)   After giving effect to any Borrowing, unless the Agent shall
otherwise consent, there may not be more than ten different Interest Periods in
effect.

      2.04  Conversion and Continuation Elections.

            (a)   The Company may upon irrevocable written notice to the Agent:

                  (i)   elect to convert on any Business Day, any Reference Rate
      Loans (or any part thereof in an amount not less than $3,000,000 or an
      integral multiple of $1,000,000 in excess thereof) into Eurodollar Rate
      Loans or CD Rate Loans;

                  (ii)  elect to convert on any Interest Payment Date, any CD
      Rate Loans or Eurodollar Rate Loans maturing on such Interest Payment Date
      (or any part thereof in an amount not less than (A) $3,000,000 or an
      integral multiple of $1,000,000 in excess thereof, in the case of a
      conversion into CD Rate Loans or Eurodollar Rate Loans, or (B) $1,000,000
      or an integral multiple of $1,000,000 in excess thereof, in the case of a
      conversion into Reference Rate Loans), in the case of CD Rate Loans, into
      Eurodollar Rate Loans or Reference Rate Loans, and in the case of
      Eurodollar Rate Loans, into CD Rate Loans or Reference Rate Loans; or

                  (iii) elect to continue, on any Interest Payment Date
      therefor, any CD Rate Loans or Eurodollar Rate Loans (or any part thereof
      in an amount not less than $3,000,000 or an integral multiple of
      $l,000,000);

provided, that if the aggregate amount of CD Rate Loans or Eurodollar Rate Loans
shall have been reduced by payment, prepayment, or conversion of part thereof to
be less than $3,000,000, the CD Rate Loans or Eurodollar Rate Loans shall
automatically convert into Reference Rate Loans, and on and after such date the
right of the Company to continue such Loans as Eurodollar Rate Loans or CD Rate
Loans, as the case may be, shall terminate.

            (b)   The Company shall deliver by telex, cable or facsimile,
confirmed immediately in an original writing, a Notice of
Conversion/Continuation to be received by the Agent not later than 9:00 a.m.
(San Francisco time) at least (i) three Business Days in advance of the
Conversion Date or continuation date, if the Loans are to be converted into or
continued as


                                       22
<PAGE>   32
Eurodollar Rate Loans; (ii) two Business Days in advance of the Conversion Date
or continuation date, if the Loans are to be converted into or continued as CD
Rate Loans; and (iii) on the Conversion Date or continuation date, if the Loans
are to be converted into Reference Rate Loans, specifying:

                        (A)   the proposed Conversion Date or continuation date;

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

                        (C)   the nature of the proposed conversion or
            continuation; and

                        (D)   the duration of the requested Interest Period, if
            applicable.

            (c)   If upon the expiration of any Interest Period applicable to CD
Rate Loans or Eurodollar Rate Loans, the Company has failed to select a new
Interest Period to be applicable to such CD Rate Loans or Eurodollar Rate Loans,
as the case may be, or if any Event of Default shall then exist, the Company
shall be deemed to have elected to convert such CD Rate Loans or Eurodollar Rate
Loans into Reference Rate Loans effective as of the expiration date of such
current Interest Period.

            (d)   Upon receipt of a Notice of Conversion/ Continuation, the
Agent will promptly notify each Bank thereof, or, if no timely notice is
provided, the Agent will promptly notify each Bank of the details of any
automatic conversion. All conversions and continuations shall be made pro rata
according to the respective outstanding principal amounts of the Loans with
respect to which the notice was given held by each Bank.

            (e)   After giving effect to any conversion or continuation of any
Loans, unless the Agent shall otherwise consent, there shall not be more than 10
different Interest Periods in effect.

      2.05  Voluntary Termination or Reduction of Commitments. The Company may,
upon not less than five Business Days' prior notice to the Agent, terminate the
Aggregate Revolving Commitment or permanently reduce the Aggregate Revolving
Commitment by an aggregate minimum amount of $5,000,000 or any multiple of $
1,000,000 in excess thereof, provided that no such reduction or termination
shall be permitted if the Effective Amount of all outstanding Revolving Loans
and L/C Obligations would exceed the Aggregate Revolving Commitment then in
effect, or (b) the Effective Amount of all L/C Obligations then outstanding
would exceed the Aggregate L/C Commitment then in effect; and, provided,
further, that once reduced in accordance with this Section 2.05, the Aggregate
Revolving Commitment and, if applicable the Aggregate L/C Commitment may not be
increased. Any reduction of the Aggregate Revolving Commitment shall be applied
to each Bank's Commitment in accordance with such Bank's Commitment Percentage.
If and to the extent specified by the Company in the notice to the Agent, some
or all of the reduction in the Aggregate Revolving Commitment shall be applied
to reduce the Aggregate L/C Commitment, subject to the first proviso of the
first sentence of this Section. If any of the Commitments are terminated in
their entirety, all accrued commitment fees


                                       23
<PAGE>   33
to the effective date of such termination shall be payable on the effective date
of such termination without any premium or penalty.

      2.06  Optional Prepayments. Subject to Section 4.04, the Company may, at
any time or from time to time, upon at least three Business Days' notice to the
Agent for CD Rate Loans or Eurodollar Rate Loans and one Business Days notice
for Reference Rate Loans, ratably prepay Loans in whole or in part, in amounts
of $2,000,000 or any multiple of $1,000,000 in excess thereof. Such notice of
prepayment shall specify the date and amount of such prepayment and whether such
prepayment is of Reference Rate Loans, CD Rate Loans or Eurodollar Rate Loans,
or any combination thereof. Such notice shall not thereafter be revocable by the
Company and the Agent will promptly notify each Bank thereof and of the amount
of such Bank's Commitment Percentage of such prepayment. If such notice is
given, the Company shall make such prepayment and the payment amount specified
in such notice shall be due and payable on the date specified therein, together
with accrued interest to each such date on the amount prepaid and the amounts
required pursuant to Section 4.04.

      2.07  Repayment.

            (a)   The Term Credit. The Company agrees to repay the principal
amount of the Term Loans in six (6) equal semi-annual installments of $5,000,000
each, beginning on December 31, 1997, and thereafter on the last Business Day of
each June and December of each year thereafter, through and including June 30,
2000 (the "Term Credit Maturity Date"), on which date the final installment
shall be due and payable.

            (b)   The Revolving Credit. The Company agrees to repay the
principal amount outstanding as of the Revolving Termination Date of the
Revolving Loans in ten equal semiannual installments (i) beginning on the last
Business Day in December, 1999 (as such date may be extended pursuant to the
terms of and subject to the conditions of subsection 2.15(b)), and (ii)
thereafter on the last Business Day of June and December of each year
thereafter, through and including the last Business Day in June, 2004 (as such
date may be extended pursuant to the terms of and subject to the conditions of
subsection 2.15(b)).

      2.08  Interest

            (a)   Subject to subsection 2.08(c), each Loan shall bear interest
on the outstanding principal amount thereof from the date when made until it
becomes due at a rate per annum equal to the CD Rate, the Eurodollar Rate or the
Reference Rate, as the case may be, plus the Applicable Margin.

            (b)   Interest on each Loan shall be payable in arrears on each
Interest Payment Date. Interest shall also be payable on the date of any
prepayment of Loans pursuant to Sections 2.05 and 2.06 for the portion of the
Loans so prepaid and upon payment (including prepayment) in full thereof and,
after the occurrence and during the continuance of any Event of Default,
interest shall be payable on demand.


                                       24
<PAGE>   34
            (c)   If any amount of principal of or interest on any Loan, or any
other amount payable hereunder or under any of the other Loan Documents is not
paid in full when due (whether at stated maturity, by acceleration, demand or
otherwise), the Company agrees to pay interest on such unpaid principal or other
amount, from the date such amount becomes due until the date such amount is paid
in full, payable on demand, at a fluctuating rate per annum equal to the
Reference Rate plus two percent.

      2.09  Fees.

            (a)   Agency Fee. The Company shall pay an agency fee to the Agent
for the Agent's own account, in the amounts and at the times as required by the
letter agreement dated as of May 30, 1997, between the Company and the Agent.

            (b)   Commitment Fees. The Company shall pay to the Agent for the
account of each Bank a commitment fee on the average daily unused portion of
such Bank's Revolving Commitment equal to 1.875% per annum. Such commitment fee
shall accrue from the Closing Date to the Revolving Termination Date and shall
be payable quarterly in arrears on the last Business Day of each calendar
quarter commencing on September 30, 1997, and on the Revolving Termination Date.
The Company shall also pay, on June 30, 1997, to the Agent for the account of
each Bank, any unpaid commitment fees due and owing under subsection 2.09(b) of
the Prior Credit Agreement through and including the Closing Date.

      2.10  Computation of Fees and Interest.

            (a)   All computations of interest payable in respect of Reference
Rate Loans shall be made on the basis of a year of 365 or 366 days, as the case
may be, and actual days elapsed. All other computations of fees and interest
under this Agreement shall be made on the basis of a 360 day year and actual
days elapsed, which results in more interest being paid than if computed on the
basis of a 365-day year. Interest and fees shall accrue during each period
during which interest or such fees are computed from the first day thereof to
the last day thereof.

            (b)   The Agent will, with reasonable promptness, notify the Company
and the Banks of each determination of a Eurodollar Rate or of a CD Rate,
provided that any failure to so shall not relieve the Company of any liability
hereunder. Any change in the interest rate on a Loan resulting from a change in
the Reserve Percentage, Eurocurrency Reserve Percentage, or the Assessment Rate
shall become effective as of the opening of business on the day on which such
change in the Reserve Percentage, Eurocurrency Reserve Percentage, or the
Assessment Rate becomes effective. The Agent will with reasonable promptness
notify the Company and the Banks of the effective date and the amount of each
such change, provided that any failure to do so shall not relieve the Company of
any liability hereunder.

            (c)   Each determination of an interest rate by the Agent pursuant
to any provision of this Agreement shall be conclusive and binding on the
Company and the Banks in the absence of manifest error.

      2.11  Payments by the Company.

            (a)   All payments (including prepayments) to be made by the Company
on account of principal, interest and fees shall be made without set-off or
counterclaim and shall be made to the Agent, for the account of the Banks
(except as otherwise provided in subsection 2.12(b) and Sections 4.01, 4.03,
4.04 and 4.06), at the Agent's office referenced in Section 11.02, in dollars
and in immediately available funds no later than 12:00 noon (San Francisco
time). The Agent will promptly distribute to each Bank the amount of its
Commitment Percentage of such principal, interest, fees or other amounts, in
like funds as received. Any payment which is received by the Agent later than
12:00 noon (San Francisco time) shall be deemed to have been received on the
immediately succeeding Business Day.

            (b)   Whenever any payment hereunder shall be stated to be due on a
day other than a Business Day, such payment shall be made on the next succeeding
Business Day, and such extension of time shall in such case be included in the
computation of interest or fees, as the case may be; subject to the provisions
set forth in the definition of "Interest Period" herein.

            (c)   Unless the Agent shall have received notice from the Company
prior to the date on which any payment is due to the Banks hereunder that the
Company will not make such payment in full, the Agent may assume that the
Company has made such payment in full to the Agent on such date and the Agent
may (but shall not be so required), in reliance upon such assumption, cause to
be distributed to each Bank on such due date an amount equal to the amount then
due such Bank. If and to the extent the Company shall not have made such payment
in full to the Agent, each Bank shall repay to the Agent on demand such amount
distributed to such Bank, together with interest thereon for each day from the
date such amount is distributed to such Bank until the date such Bank repays
such amount to the Agent, at the Federal Funds Rate as in effect on such date.

      2.12  Payments by the Banks to the Agent.

            (a)   Each Bank shall make available to the Agent in immediately
available funds for the account of the Company an amount equal to the product of
(i) its Commitment Percentage times (ii) the amount of any Borrowing.

            (b)   Unless the Agent shall have received notice from a Bank on or
prior to the Closing Date or, with respect to each Borrowing after the Closing
Date, at least one Business Day prior to the date of any proposed Borrowing,
that such Bank will not make available to the Agent for the account of the
Company the amount of that Bank's Commitment Percentage of the Borrowing, the
Agent may assume that each Bank has made such amount available to the Agent on
the borrowing date and the Agent may (but shall not be so required), in reliance
upon such assumption, make available to the Company on such date a corresponding
amount. If and to the extent any Bank shall not have made its full amount
available to the Agent and the Agent in such circumstances has made available to
the Company such amount, that Bank shall within two Business Days following the
date of such Borrowing make such amount available to the Agent, together with
interest at the Federal Funds Rate for each day during such period. A
certificate of


                                       26
<PAGE>   36
the Agent submitted to any Bank with respect to amounts owing under this
subsection 2.12(b) shall be conclusive, absent manifest error. If such amount is
so made available, such payment to the Agent shall constitute such Bank's Loan
on the date of Borrowing for all purposes of this Agreement. If such amount is
not made available to the Agent within two Business Days following the date of
such Borrowing, the Agent shall notify the Company of such failure to fund and,
upon demand by the Agent, the Company shall pay such amount to the Agent for the
Agent's account, together with interest thereon for each day elapsed since the
date of such Borrowing, at a rate per annum equal to the interest rate
applicable at the time to the Loans comprising such Borrowing; provided,
however, that the Company shall not be obligated to pay any amounts pursuant to
Section 4.04 as a result of such payment.

            (c)   The failure of any Bank to make any Loan on any date of
Borrowing shall not relieve any other Bank of any obligation hereunder to make a
Loan on the date of such Borrowing, but no Bank shall be responsible for the
failure of any other Bank to make the Loan to be made by such other Bank on the
date of any Borrowing.

      2.13  Sharing of Payments, Etc. If, other than as provided in Section
4.01, 4.03, 4.04 or 4.06, any Bank shall obtain on account of the Loans made by
it, any payment (whether voluntary, involuntary, through the exercise of any
right of set-off, or otherwise) in excess of its Commitment Percentage of
payments on account of the Loans obtained by all the Banks, such Bank shall
forthwith (a) notify the Agent of such fact, and (b) purchase from the other
Banks such participations in the Loans made by them as shall be necessary to
cause such purchasing Bank to share the excess payment ratably with each of
them; provided, however, that if all or any portion of such excess payment is
thereafter recovered from the purchasing Bank, such purchase shall to that
extent be rescinded and each other Bank shall repay to the purchasing Bank the
purchase price paid thereto together with an amount equal to such paying Bank's
Commitment Percentage (according to the proportion of (i) the amount of such
paying Bank's required repayment to (ii) the total amount so recovered from the
purchasing Bank) of any interest or other amount paid or payable by the
purchasing Bank in respect of the total amount so recovered. The Company agrees
that any Bank so purchasing a participation from another Bank pursuant to this
Section 2.13 may, to the fullest extent permitted by law, exercise all its
rights of payment (including the right of set-off, but subject to Section
11.08(a)) with respect to such participation as fully as if such Bank were the
direct creditor of the Company in the amount of such participation. The Agent
shall keep records (which shall be conclusive and binding in the absence of
manifest error), of participations purchased pursuant to this Section 2.13 and
shall in each case notify the Banks following any such purchases.

      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 Person becomes a 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 Subsidiary to
execute and deliver to the Agent and the Banks a guaranty of the Obligations in
substantially the form of the Guaranty, along with such other items as
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.

      2.15  Extension of Revolving Termination Date. (a) Not earlier than April
30, 1998 and not later than April 30, 1999, 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.

            (b)   In each instance that the Revolving Termination Date shall
have been extended pursuant to subsection (a) of this Section, the date on which
the first installment of principal is due under clause (i) of subsection 2.07(b)
shall be extended to the last Business Day of the year in which the Revolving
Termination Date (as so extended) occurs (such last Business Day, the "First
Principal Payment Date"), and the date on which the last installment of
principal is due under clause (ii) of subsection 2.07(b) shall be extended to
the last Business Day in June of the year which is five years after the year in
which the First Principal Payment Date occurs.


                                   ARTICLE III

(i) the Issuing Bank agrees prior to the Revolving Termination Date (A) to issue
Letters of Credit for the account of the Company or its Subsidiaries (it being

exceed) the Aggregate L/C Commitment. Within the foregoing limits, and subject
to the other terms and conditions hereof, the Company's ability to obtain

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

                  (ii)  the Issuing Bank has received written notice from any

                  (iii) the expiry date of any requested Letter of Credit, other
      than a Retention Letter of Credit, is (x) more than one year after the
      date of issuance, unless the Issuing Bank and the Majority Banks have
      approved such expiry date in writing, or (y) after the Revolving
      Termination Date, unless all the Banks have approved such expiry date in
      writing; or the expiry date of any requested Retention Letter of Credit is

      drafts, or is not otherwise in form and substance acceptable to the
      Issuing Bank;

                  (v)   such Letter of Credit, other than a Retention Letter of
      Credit, is to be used for any purpose other than to support the Company's
      workers' compensation program, unless the Issuing Bank and the Majority
      Banks have approved such other purpose in


                                       29
<PAGE>   39
      writing; or such Retention Letter of Credit is to be used for any purpose
      other than to provide security in lieu of retention under any construction
      contract entered into by the Company, unless the Issuing Bank and the
      Majority Banks have approved such other purpose in writing; or

                  (vi)  the face amount of any requested Retention Letter of
      Credit is less than $ 1,000,000.

      3.02  Issuance and Amendment of Letters of Credit.

            (a)   Each Letter of Credit shall be Issued upon the irrevocable
written request of the Company received by the Issuing Bank (with a copy sent by
the Company to the Agent) at least ten days (or such shorter time as the Issuing
Bank may agree in a particular instance in its sole discretion) prior to the
proposed date of issuance. Each such request for issuance of a Letter of Credit
shall be by telecopy, telex or cable, confirmed immediately in an original
writing, in substantially the form of Exhibit C, or an application form for
issuances of standby letters of credit as shall at any time be in use at the
applicable Issuing Bank, as such Issuing Bank shall request ("Letter of Credit
Application") and shall specify in form and detail satisfactory to the Issuing
Bank: (i) the proposed date of issuance of the Letter of Credit (which shall be
a Business Day); (ii) the face amount of the Letter of Credit (provided that
the face amount of any Retention Letter of Credit shall not be less than 
$1,000,000); (iii) the expiry date of the Letter of Credit; (iv) the name and
address of the beneficiary thereof; (v) the documents to be presented by the
beneficiary of the Letter of Credit in case of any drawing thereunder; (vi) the
full text of any certificate to be presented by the beneficiary in case of any
drawing thereunder; and (vii) such other matters as the Issuing Bank may
require. This Agreement shall control in the event of any conflict with a Letter
of Credit Application.

            (b)   At least two Business Days prior to the Issuance of any Letter
of Credit or any amendment of any Letter of Credit, the Issuing Bank will
confirm with the Agent (by telephone or in writing) that the Agent has received
a copy of the Letter of Credit Application or Amendment Application from the
Company and, if not, the Issuing Bank will provide the Agent with a copy of
same. Unless the Issuing Bank has received notice on or before the Business Day
immediately preceding the date the Issuing Bank is to Issue a requested Letter
of Credit (A) from the Agent directing the Issuing Bank not to issue additional
Letters of Credit because (x) the available Revolving Commitments equal zero, or
the aggregate amount of all L/C Obligations equals or exceeds the Aggregate L/C
Commitment; or (y) the stated amount of the Letter of Credit the Issuing Bank is
being requested to issue exceeds the available Revolving Commitments or would
cause the Effective Amount of the L/C Obligations to exceed the Aggregate L/C
Commitment; or (B) from the Agent or any Bank that one or more conditions
specified in Article V are not then satisfied; then subject to the terms and
conditions hereof, the Issuing Bank will, on the requested date, Issue a Letter
of Credit for the account of the Company or amend or reinstate a Letter of
Credit, as the case may be, in accordance with the Issuing Bank's usual and
customary business practices.

            (c)   From time to time while a Letter of Credit is outstanding and
prior to the Revolving Termination Date, the Issuing Bank will, upon the written
request of the Company in form and substance satisfactory to the Issuing Bank
(an "Amendment Application"), with a copy sent by the Company to the Agent,
amend any Letter of Credit Issued by it; provided that the Issuing Bank shall be
under no obligation to amend any Letter of Credit if:

                  (i)   the Issuing Bank would have no obligation at such time
      to Issue such Letter of Credit in its amended form at such time under the
      terms of this Agreement; or

                  (ii)  the beneficiary of any such Letter of Credit does not
      accept the Letter of Credit as amended.

            (d)   From time to time while a Letter of Credit is outstanding
after the Revolving Termination Date (subject to clause (iii) of subsection
3.01(b)), the Issuing Bank will, upon submission to the Issuing Bank of an
Amendment Application in form and substance satisfactory to the Issuing Bank,
with a copy sent by the Company to the Agent, amend any Letter of Credit Issued
by it; provided that the Issuing Bank shall be under no obligation to amend any
Letter of Credit after the Revolving Termination Date if:

                  (i)   such Letter of Credit in its amended form would have an
      expiry date subsequent to that of the Letter of Credit as to which the
      Amendment Application has been submitted;

                  (ii)  such Letter of Credit in is amended form would have an
      amount available for drawing in excess of that of the Letter of Credit as
      to which the Amendment Application has been submitted;

                  (iii) a Default or Event of Default has occurred and is
      continuing as of the date of the Amendment Application; or

                  (iv)  the beneficiary of any such Letter of Credit does not
      accept the Letter of Credit as amended.

            (e)   The Agent will promptly notify the Banks of the receipt by it
of any Letter of Credit Application or Amendment Application.

            (f)   The Issuing Bank may, at its election (or as required by the
Agent at the direction of the Majority Banks), deliver any notices of
termination or other communications to any Letter of Credit (other than a
Retention Letter of Credit) beneficiary or transferee, or take any other action
as necessary or appropriate, at any time and from time to time, in order to
cause the expiry date of such Letter of Credit (other than a Retention Letter of
Credit) to be a date not later than the Revolving Termination Date.

      3.03  Participations, Drawings and Reimbursements.

            (a)   As of the Closing Date, the Existing Letters of Credit will be
deemed for all purposes Letters of Credit Issued and outstanding under this
Article III, and will be governed by applications and agreements pertaining
thereto and by this Agreement (which shall control in the event of a conflict).
Each Bank (other than the Issuing Bank) shall be deemed to, and hereby
irrevocably and unconditionally agrees to, purchase from the Issuing Bank on the
Closing Date a participation in such Letters of Credit and each drawing
thereunder in an amount equal to the product of (i) the Commitment Percentage of
the Bank, times (ii) the face amount of such Letters of Credit. For purposes of
subsection 3.01 (a), the Existing Letters of Credit shall be deemed to utilize
the Revolving Commitment of each Bank (other than the Issuing Bank) by an amount
equal to the amount of such participation and to utilize the Revolving
Commitment of the Issuing Bank by an amount equal to the face amount of such
Letters of Credit less the aggregate amount of such participations.

            (b)   Immediately upon the Issuance of each Letter of Credit in
addition to that described in subparagraph (a), each Bank (other than the
applicable Issuing Bank) shall be deemed to, and hereby irrevocably and
unconditionally agrees to, purchase from the Issuing Bank a participation in
such Letter of Credit and each drawing thereunder in an amount equal to the
product of (i) the Commitment Percentage of the Bank, times (ii) the face amount
of such Letter of Credit. For purposes of subsection 3.01(a), each Issuance of a
Letter of Credit shall be deemed to utilize the Revolving Commitment of each
Bank (other than the applicable Issuing Bank) by an amount equal to the amount
of such participation and to utilize the Revolving Commitment of the Issuing
Bank by an amount equal to the face amount of such Letter of Credit less the
aggregate amount of such participations.

            (c)   In the event of any request for a drawing under a Letter of
Credit by the beneficiary or transferee thereof, the applicable Issuing Bank
will promptly notify the Company. The Company shall reimburse the Issuing Bank
prior to 11:00 a.m. (San Francisco time), on each date that any amount is paid
by the Issuing Bank under any Letter of Credit, in an amount equal to the amount
so paid by the Issuing Bank. In the event the Company shall fail to reimburse
the Issuing Bank the full amount of any drawing under any Letter of Credit by
11:00 a.m. (San Francisco time) on the same date such drawing is honored by the
Issuing Bank, the Issuing Bank will promptly notify the Agent and the Agent will
promptly notify each Bank thereof, and, if such drawing occurs before the
Revolving Termination Date, the Company shall be deemed to have requested that
Reference Rate Loans be made by the Banks to be disbursed on the date of payment
by the Issuing Bank under the Letter of Credit, subject to the amount of the
unutilized portion of the Revolving Commitment and subject to the conditions set
forth in Section 5.02. If such drawing on any Letter of Credit occurs on or
after the Revolving Termination Date, the Company shall be deemed to have
incurred from the Issuing Bank a L/C Borrowing in the amount of such drawing,
which shall be due and payable and shall bear interest in accordance with the
terms of subsection 3.03(e) hereof. Any notice given by the Issuing Bank or the
Agent pursuant hereto may be oral if immediately confirmed in writing (including
by facsimile); provided that the lack of such an immediate confirmation shall
not affect the conclusiveness or binding effect of such notice.


                                       32
<PAGE>   42
            (d)   Each Bank will upon receipt of any notice pursuant to
subsection 3.03(c) make available to the Agent for the account of the Issuing
Bank an amount in immediately available funds equal to its Commitment Percentage
of the amount of the drawing, whereupon the participating Banks shall (subject
to subsection 3.03(e)) each be deemed to have made a Revolving Loan consisting
of a Reference Rate Loan to the Company in that amount. If any Bank so notified
shall fail to make available to the Agent for the account of the Issuing Bank
the amount of such Bank's Commitment Percentage of the amount of the drawing by
no later than 12:00 noon (San Francisco time) on the date such drawing was
honored by the Issuing Bank (the "Participation Date"), then interest shall
accrue on such Bank's obligation to make such payment, from the Participation
Date to the date such Bank makes such payment at a rate per annum equal to the
Federal Funds Rate in effect from time to time. The Agent will promptly give
notice of the occurrence of the Participation Date, but failure of the Agent to
give any such notice on the Participation Date or in sufficient time to enable
any Bank to effect such payment on such date shall not relieve such Bank from
its obligations under this Section 3.03.

            (e)   With respect to any unreimbursed drawing which is not
converted into Revolving Loans consisting of Reference Rate Loans to the Company
in whole or in part, because of the Company's failure to satisfied the
conditions set forth in Section 5.02, because the drawing on any Letter of
Credit occurred on or after the Revolving Termination Date, or for any other
reason, the Company shall be deemed to have incurred from the Issuing Bank a L/C
Borrowing in the amount of such drawing, which L/C Borrowing shall be due and
payable on demand (together with interest) and shall bear interest until such
demand at a rate per annum equal to the Reference Rate plus two percent, and
each Bank's payment to the Issuing Bank pursuant to subsection 3.03(d) shall be
deemed a L/C Advance in satisfaction of its participation obligation under this
Section 3.03.

      3.04  Repayment of Participations.

            (a)   Upon (and only upon) receipt by the Agent for the account of
the Issuing Bank of funds from the Company (i) in reimbursement of any payment
made by the Issuing Bank under any Letter of Credit with respect to which any
Bank has theretofore paid the Agent for the account of the Issuing Bank for such
Bank's participation in such Letter of Credit pursuant to Section 3.03, or (ii)
in payment of interest thereon; the Agent will pay to each Bank, in the same
funds as those received by the Agent for the account of the Issuing Bank, the
amount of such Bank's Commitment Percentage of such funds, and the Issuing Bank
shall receive the amount of the Commitment Percentage of such funds of any Bank
that did not so pay the Agent for the account of the Issuing Bank.

            (b)   If the Agent or the Issuing Bank is required at any time to
return to the Company or to a trustee, receiver, liquidator, custodian, or any
official in any Insolvency Proceeding, any portion of the payments made by the
Company to the Agent for the account of the Issuing Bank pursuant to subsection
3.04(a) in reimbursement of a payment made under any Letter of Credit or
interest thereon, each Bank shall, on demand of the Agent, forthwith return to
the Agent or the Issuing Bank the amount of its Commitment Percentage of any
amounts so returned by the Agent or the Issuing Bank plus interest thereon from
the date such demand is


                                       33
<PAGE>   43
made to the date such amounts are returned by such Bank to the Agent or the
Issuing Bank, at a rate per annum equal to the Federal Funds Rate in effect from
time to time.

      3.05  Role of the Issuing Bank.

            (a)   Each Bank agrees that, in paying any drawing under a Letter of
Credit, the Issuing Bank shall not have any responsibility to obtain any
document (other than any sight draft and certificates expressly required by the
Letter of Credit) or to ascertain or inquire as to the validity or accuracy of
any such document or the authority of the Person executing or delivering any
such document. Neither the Issuing Bank nor any of its Affiliates,
correspondents, participants or assignees, or any of their respective officers,
directors or employees, shall be liable to any Bank for:

                  (i)   any action taken or omitted in connection herewith at
      the request or with the approval of the Banks (including the Majority
      Banks, as applicable);

                  (ii)  any action taken or omitted in the absence of gross
      negligence or wilful misconduct; or

                  (iii) the due execution, effectiveness, validity or
      enforceability of any L/C-Related Document.

            (b)   The Company hereby assumes all risks of the acts or omissions
of any beneficiary or transferee with respect to its use of any Letter of
Credit; provided, however, that this assumption is not intended to, and shall
not, preclude the Company's pursuing such rights and remedies as it may have
against the beneficiary or transferee at law or under any other agreement.
Neither the Issuing Bank, nor any of its Affiliates, correspondents,
participants or assignees, or any of their respective officers, directors or
employees, shall be liable or responsible for any of the matters described in
paragraphs (i) through (vii) of Section 3.06; provided, however, anything in
such clauses to the contrary notwithstanding, that the Company may have a claim
against the Issuing Bank, and the Issuing Bank may be liable to the Company, to
the extent, but only to the extent, of any direct, as opposed to consequential
or exemplary, damages suffered by the Company which the Company proves were
caused by (i) the Issuing Bank's willful misconduct or gross negligence or (ii)
the Issuing Bank's willful failure to pay under any Letter of Credit after the
presentation to it by the beneficiary of a sight draft and certificate both
strictly complying with the terms and conditions of a Letter of Credit. In
furtherance and not in limitation of the foregoing, the Issuing Bank may accept
documents that appear on their face to be in order, without responsibility for
further investigation, regardless of any notice or information to the contrary.

      3.06  Obligations Absolute. The obligations of the Company under this
Agreement and any L/C-Related Document to reimburse the Issuing Bank, and to
repay L/C Borrowings and L/C Borrowings converted into Revolving Loans, shall be
unconditional and irrevocable, and shall be paid strictly in accordance with the
terms of this Agreement and such other L/C-Related Document under all
circumstances, including the following:


                                       34
<PAGE>   44
                  (i)   any lack of validity or enforceability of this
      Agreement, any Letter of Credit or any other L/C-Related Document;

                  (ii)  any change in the time, manner or place of payment of,
      or in any other term of, all or any of the obligations of the Company in
      respect of any Letter of Credit or any other amendment or waiver of or any
      consent to departure from all or any of the L/C-Related Documents;

                  (iii) the existence of any claim, set-off, defense or other
      right that the Company may have at any time against any beneficiary or any
      transferee of any Letter of Credit (or any Person for whom any such
      beneficiary or any such transferee may be acting), the Issuing Bank or any
      other Person, whether in connection with this Agreement, the transactions
      contemplated hereby or by the L/C-Related Documents or any unrelated
      transaction;

                  (iv)  any certificate or other document presented under any
      Letter of Credit proving to be forged, fraudulent, invalid or insufficient
      in any respect or any statement therein being untrue or inaccurate in any
      respect;

                  (v)   any payment by the Issuing Bank under any Letter of
      Credit against presentation of a draft or certificate that does not
      strictly comply with the terms of any Letter of Credit; or any payment is
      made by the Issuing Bank under any Letter of Credit to any Person
      purporting to be a trustee in bankruptcy, debtor-in-possession, assignee
      for the benefit of creditors, liquidator, receiver or other representative
      of or successor to any beneficiary or any transferee of any Letter of
      Credit, including any arising in connection with any Insolvency
      Proceeding;

                  (vi)  any exchange, release or non-perfection of any
      collateral, or any release or amendment or waiver of or consent to
      departure from any other guarantee, for all or any of the obligations of
      the Company in respect of any Letter of Credit; or

                  (vii) any other circumstance or happening whatsoever, whether
      or not similar to any of the foregoing, including any other circumstance
      that might otherwise constitute a defense available to, or a discharge of,
      the Company or a guarantor.

      3.07  Cash Collateral Pledge. Upon the request of Agent, (i) if the
Issuing Bank has honored any full or partial drawing request on any Letter of
Credit or (ii) if, as of the Revolving Termination Date, any Letters of Credit
(other than any Retention Letters of Credit) may for any reason remain
outstanding and partially or wholly undrawn, or (iii) if, after the Revolving
Termination Date, any Retention Letters of Credit remain outstanding and
partially or wholly undrawn and there shall occur a Default or Event of Default,
the Company shall immediately pay over, pledge and deliver, pursuant to a
security agreement in form and substance acceptable to the Agent, cash in an
amount equal to the maximum amount available for drawing under any outstanding
Letters of Credit, to the Agent for the benefit of the Banks as collateral.


                                       35
<PAGE>   45
      3.08  Letter of Credit Fees. The Company shall pay to the Agent for the
benefit of the Banks letter of credit fees equal to (i) 0.500% per annum, in
each case of the face amount of outstanding Letters of Credit other than
Retention Letters of Credit, and (ii) 0.325% per annum, in each case of the face
amount of outstanding Retention Letters of Credit. Such fees shall be payable
quarterly in arrears on the last day of each calendar quarter. The Company shall
pay BofA, in its capacity as Issuing Bank, a letter of credit fronting fee in
the amount and at the times as set forth in a letter agreement between the
Company and BofA, as Issuing Bank, dated as of May 30, 1997, and shall pay any
other Issuing Bank a letter of credit fronting fee as agreed to from time to
time by the Company and such Issuing Bank.

      3.09  Additional Issuing Bank. If BofA as Issuing Bank declines to Issue a
requested Letter of Credit due to the circumstances set forth in clause (i) of
subsection 3.01(b), then the Company shall have the right to designate an
additional Bank as an Issuing Bank hereunder, provided that such Issuing Bank
shall have notified the Agent in writing prior to the Issuance of any Letter of
Credit by it that it is an Issuing Bank hereunder with respect to Letters of
Credit and upon receipt by Agent of such notice, the definition of 'Issuing
Bank' hereunder shall be deemed to be amended thereby.


                                   ARTICLE IV

                     TAXES, YIELD PROTECTION AND ILLEGALITY

      4.01  Taxes.

            (a)   Subject to subsection 4.01(g), any and all payments by the
Company to each Bank or the Agent under this Agreement shall be made free and
clear of, and without deduction or withholding for, any and all present or
future taxes, levies, imposts, deductions, charges or withholdings, and all
liabilities with respect thereto, excluding, in the case of each Bank and the
Agent, such taxes (including income taxes or franchise taxes) as are imposed on
or measured by each Bank's net income by the jurisdiction under the laws of
which such Bank or the Agent, as the case may be, is organized or maintains a
Lending Office or any political subdivision thereof (all such non-excluded
taxes, levies, imposts, deductions, charges, withholdings and liabilities being
hereinafter referred to as "Taxes").

            (b)   In addition, the Company shall pay any present or future stamp
or documentary taxes or any other excise or property taxes, charges or similar
levies which arise from any payment made hereunder or from the execution,
delivery or registration of, or otherwise with respect to, this Agreement or any
other Loan Documents (hereinafter referred to as "Other Taxes").

            (c)   Subject to subsection 4.01(g), the Company shall indemnify and
hold harmless each Bank and the Agent for the fall amount of Taxes or Other
Taxes (including without limitation, any Taxes or Other Taxes imposed by any
jurisdiction on amounts payable under this Section 4.01) paid by the Bank or the
Agent in the amount that the respective Bank


                                       36
<PAGE>   46
specifies as necessary to preserve the after-tax yield the Bank would have
received if such Taxes or Other Taxes had not been imposed, and any liability
(including penalties, interest, additions to tax and expenses) arising therefrom
or with respect thereto, whether or not such Taxes or Other Taxes were correctly
or legally asserted and any liability (including penalties, interest, additions
to tax and expenses) arising therefrom or with respect thereto, whether or not
such Taxes or Other Taxes were correctly or legally asserted. Payment under this
indemnification shall be made within 30 days from the date the Bank or the Agent
makes written demand therefor. Should the Agent or a Bank determine in its sole
discretion to seek a refund or rebate of some or all of the amount of Taxes,
Other Taxes or other liability paid by it and for which it was indemnified by
the Company and should it receive some or all of the refund or rebate which it
sought, it shall return to the Company the difference between the amount of such
refund or rebate and its reasonable costs and expenses of counsel (and the
allocated cost of internal counsel) incurred by it in procuring such refund or
rebate.

            (d)   If the Company shall be required by law to deduct or withhold
any Taxes or Other Taxes from or in respect of any sum payable hereunder to any
Bank or the Agent; then, subject to subsection 4.01(g):

                  (i)   the sum payable shall be increased as necessary so that
      after making all required deductions (including deductions applicable to
      additional sums payable under this Section 4.01) such Bank or the Agent,
      as the case may be, receives an amount equal to the sum it would have
      received had no such deductions been made;

                  (ii)  the Company shall make such deductions; and

                  (iii) the Company shall pay the full amount deducted to the
      relevant taxation authority or other authority in accordance with
      applicable law.

            (e)   Within 30 days after the date of any payment by the Company of
Taxes or Other Taxes, the Company shall furnish to the Agent the original or a
certified copy of a receipt evidencing payment thereof, or other evidence of
payment satisfactory to the Agent.

            (f)   Each Bank which is a foreign person (i.e., a person other than
a United States person for United States Federal income tax purposes) agrees
that:

                  (i)   it shall, no later than the Closing Date (or, in the
      case of a Bank which becomes a part hereto pursuant to Section 11.07 after
      the Closing Date, the date upon which the Bank becomes a part hereto)
      deliver to the Company through the Agent:

                        (A)   if any Lending Office is located in the United
            States, two accurate and complete signed originals of Internal
            Revenue Service Form 4224 or any successor thereto ("Form 4224"),
            and

                        (B)   if any Lending Office is located outside the
            United States, two accurate and complete signed originals of
            Internal Revenue Service Form 1001


                                       37
<PAGE>   47
            or any successor thereto ("Form 1001"), in each case indicating that
            the Bank is on the date of delivery thereof entitled to receive
            payments of principal, interest and fees for the account of such
            Lending Office or Offices under this Agreement free from withholding
            of United States Federal income tax;

                  (ii)  if at any time the Bank changes its Lending Office or
      Offices or selects an additional Lending Office as herein provided, it
      shall with reasonable promptness deliver to the Company through the Agent
      in replacement for, or in addition to, the forms previously delivered by
      it hereunder:

                        (A)   if such changed or additional Lending Office is
            located in the United States, two accurate and complete signed
            originals of Form 4224; or

                        (B)   otherwise, two accurate and complete signed
            originals of Form 1001,

      in each case indicating that the Bank is on the date of delivery thereof
      entitled to receive payments of principal, interest and fees for the
      account of such changed or additional Lending Office under this Agreement
      free from withholding of United States federal income tax;

                  (iii) it shall, before or promptly after the occurrence of
        any event (including the passing of time but excluding any event
        mentioned in (ii) above) requiring a change in the most recent Form 4224
        or Form 1001 previously delivered by such Bank and if the delivery of
        the same be lawful, deliver to the Company through the Agent two
        accurate and complete original signed copies of Form 4224 or Form 1001
        in replacement for the forms previously delivered by the Bank; and

                  (iv)  it shall, promptly upon the Company's reasonable request
      to that effect, deliver to the Company such other forms or similar
      documentation as may be required from time to time by any applicable law,
      treaty, rule or regulation in order to establish such Bank's tax status
      for withholding purposes.

            (g)   The Company will not be required to pay any additional amounts
in respect of United States federal income tax pursuant to subsection 4.01(d) to
any Bank for the account of any Lending Office of such Bank:

                  (i)   if the obligation to pay such additional amounts would
      not have arisen but for a failure by such Bank to comply with its
      obligations under subsection 4.01(f) in respect of such Lending Office;

                  (ii)  if such Bank shall have delivered to the Company a Form
      4224 in respect of such Lending Office pursuant to subsection
      4.01(f)(i)(A), and such Bank shall not at any time be entitled to
      exemption from deduction or withholding of United States federal income
      tax in respect of payments by the Company hereunder for the account of


                                       38
<PAGE>   48
      such Lending Office for any reason other than a change in United States
      law or regulations or in the official interpretation of such law or
      regulations by any governmental authority charged with the interpretation
      or administration thereof (whether or not having the force of law) after
      the date of delivery of such Form 4224; or

                  (iii) if the Bank shall have delivered to the Company a Form
      1001 in respect of such Lending Office pursuant to Section 4.01(f)(i)(B),
      and such Bank shall not at any time be entitled to exemption from
      deduction or withholding of United States Federal income tax in respect of
      payments by the Company hereunder for the account of such Lending Office
      for any reason other than a change in United States law or regulations or
      any applicable tax treaty or regulations or in the official interpretation
      of any such law, treaty or regulations by any governmental authority
      charged with the interpretation or administration thereof (whether or not
      having the force of law) after the date of delivery of such Form 1001.

            (h)   If the Company is required to pay additional amounts to any
Bank or the Agent pursuant to subsection 4.01(d), then such Bank shall use its
reasonable best efforts (consistent with legal and regulatory restrictions) to
change the jurisdiction of its Lending Office so as to eliminate any such
additional payment by the Company which may thereafter accrue if such change in
the judgment of such Bank is not otherwise disadvantageous to such Bank.

      4.02  Illegality.

            (a)   If any Bank shall determine that the introduction of any
Requirement of Law or any change in or in the interpretation or administration
thereof has made it unlawful, or that any central bank or other Governmental
Authority has asserted that it is unlawful, for any Bank or its Lending Office
to make Eurodollar Rate Loans, then, on notice thereof by the Bank to the
Company through the Agent, the obligation of the Bank to make Eurodollar Rate
Loans shall be suspended until the Bank shall have notified the Agent and the
Company that the circumstances giving rise to such determination no longer
exists.

            (b)   If a Bank shall determine that it is unlawful to maintain any
Eurodollar Rate Loan, the Company shall prepay in full all Eurodollar Rate Loans
of the Bank then outstanding, together with interest accrued thereon, either on
the last day of the Interest Period thereof if the Bank may lawfully continue to
maintain such Eurodollar Rate Loans to such day, or immediately, if the Bank may
not lawfully continue to maintain such Eurodollar Rate Loans. The Company may in
such event borrow one or more Reference Rate Loans or CD Rate Loans in
accordance with Article II hereof.

            (c)   If the obligation of any Bank to make or maintain Eurodollar
Rate Loans has been terminated, the Company may elect, by giving notice to the
Bank through the Agent, that all Loans requested by it which would otherwise be
made by the Bank as Eurodollar Rate Loans shall be instead Reference Rate Loans.


                                       39
<PAGE>   49
            (d)   Before giving any notice to the Agent pursuant to this Section
4.02, the affected Bank shall designate a different Lending Office with respect
to its Eurodollar Rate Loans if such designation will avoid the need for giving
such notice or making such demand and will not, in the judgment of the Bank, be
illegal or otherwise significantly disadvantageous to the Bank.

      4.03  Increased Costs and Reduction of Return.

            (a)   If any Bank shall determine that, due to either (i) the
introduction of or any change (other than any change by way of imposition of or
increase in reserve requirements included in the calculation of the CD Rate or
the Eurodollar Rate or in respect of the assessment rate payable by any Bank to
the FDIC for insuring U.S. Deposits) in or in the interpretation of any law or
regulation or (ii) the compliance with any guideline or request from any central
bank or other Governmental Authority (whether or not having the force of law),
there shall be any increase in the cost to such Bank or any corporation
controlling such Bank of agreeing to make or making, funding or maintaining any
Eurodollar Rate Loans or CD Rate Loans or participating in Letters of Credit,
or, in the case of the Issuing Bank, any increase in the cost to the Issuing
Bank of agreeing to issue, issuing or maintaining any Letter of Credit or of
agreeing to make or making, funding or maintaining any unpaid drawing under any
Letter of Credit, then the Company shall be liable for, and shall from time to
time, upon demand therefor by such Bank (with a copy of such demand to the
Agent), pay to the Agent for the account of such Bank, additional amounts as are
sufficient to compensate such Bank for such increased costs.

            (b)   If any Bank shall have determined that the introduction of any
applicable law, rule, regulation or guideline regarding capital adequacy, or any
change therein or any change in the interpretation or administration thereof by
any central bank or other Governmental Authority charged with the interpretation
or administration thereof, or compliance by the Bank (or its Lending Office) or
any corporation controlling the Bank, with any request, guideline or directive
regarding capital adequacy (whether or not having the force of law) of any such
central bank or other authority, affects or would affect the amount of capital
required or expected to be maintained by the Bank or any corporation controlling
the Bank and (taking into consideration such Bank's or such corporation's
policies with respect to capital adequacy and such Bank's desired return on
capital) determines that the amount of such capital is increased as at
consequence of its Commitments, loans, credits or obligations under this
Agreement, then, upon demand of such Bank (with a copy of such demand to the
Agent), the Company shall immediately pay to the Bank, from time to time as
specified by the Bank, additional amounts sufficient to compensate the Bank for
such increase. In determining any amount due under subsection (a) or (b) of this
Section, the affected Bank may use any reasonable averaging and attribution
methods. No Bank shall be able to recover any amounts under this Section where
such amounts were incurred or accrued more than 180 days prior to the date
demand for such amounts is given to the Company.

      4.04  Funding Losses. The Company agrees to reimburse each Bank and to
hold each Bank harmless from any loss or expense which the Bank may sustain or
incur as a consequence of:


                                       40
<PAGE>   50
            (a)   the failure of the Company to make any payment (when due) or
prepayment of principal of any Eurodollar Rate Loan or CD Rate Loan (including
payments made after any acceleration thereof in accordance with Section 9.02);

            (b)   the failure of the Company to borrow, continue or convert a
Loan after the Company has given (or is deemed to have given) a Notice of
Borrowing or a Notice of Conversion/ Continuation (other than as a result of
Section 4.05);

            (c)   the failure of the Company to make any prepayment after the
Company has given a notice in accordance with Section 2.06; or

            (d)   the prepayment of a Eurodollar Rate Loan or a CD Rate Loan on
a day which is not the last day of the Interest Period with respect thereto
(other than as a result of an event requiring prepayment by the Company under
subsection 2.12(b));

including any such loss or expense arising from the liquidation or reemployment
of funds obtained by it to maintain its Eurodollar Rate Loans or CD Rate Loans
hereunder or from fees payable to terminate the deposits from which such funds
were obtained. For purposes of calculating amounts payable by the Company to the
Banks under this Section and under subsection 4.03(a), each Eurodollar Rate Loan
and CD Rate Loan made by a Bank (and each related reserve, special deposit or
similar requirement) shall be conclusively deemed to have been funded at the
IBOR used in determining the Eurodollar Rate for such Eurodollar Rate Loan or at
the Certificate of Deposit Rate used in determining the CD Rate for such CD Rate
Loan, as applicable, by a matching deposit or other borrowing in the interbank
eurodollar market, or dollar certificates of deposit, as applicable, for a
comparable amount and for a comparable period, whether or not such Eurodollar
Rate Loan or CD Rate Loan is in fact so funded.

      4.05  Inability to Determine Rates. If the Agent shall have determined
that for any reason adequate and reasonable means do not exist for ascertaining
the Eurodollar Rate or the CD Rate for any requested Interest Period with
respect to a proposed Eurodollar Rate Loan or CD Rate Loan or if the Majority
Banks shall have determined that for any reason the Eurodollar Rate or the CD
Rate applicable pursuant to subsection 2.08(a) for any requested Interest Period
with respect to a proposed Eurodollar Rate Loan or CD Rate Loan does not
adequately and fairly reflect the cost to such Banks of funding such Loan, the
Agent will forthwith give notice of such determination to the Company and each
Bank. Thereafter, the obligation of the Banks to make or maintain CD Rate Loans
or Eurodollar Rate Loans, as the case may be, hereunder shall be suspended until
the Agent revokes such notice in writing. Upon receipt of such notice, the
Company may revoke any Notice of Borrowing or Notice of Conversion/ Continuation
then submitted by it; provided, however, that the Company shall not be obligated
to pay any amounts pursuant to Section 4.04 as a result of such revocation of
notice. If the Company does not revoke such notice, the Banks shall make,
convert or continue the Loans, as proposed by the Company, in the amount
specified in the applicable notice submitted by the Company, but such Loans
shall be made, converted or continued as Reference Rate Loans instead of CD Rate
Loans or Eurodollar Rate Loans, as the case may be.

<PAGE>   51
      4.06  Certificates of Banks. Any Bank claiming reimbursement or
compensation pursuant to this Article IV shall deliver to the Company (with a
copy to the Agent) a certificate setting forth in reasonable detail the amount
payable to the Bank hereunder and such certificate shall be conclusive and
binding on the Company in the absence of manifest error.

      4.07  Survival. The agreements and obligations of the Company in this
Article IV shall survive the payment of all other Obligations.

good record and marketable title in fee simple to or valid leasehold interests

decree shall be rendered against the Company or any of its Subsidiaries which
does have or is reasonably likely to have a Material Adverse Effect, and either
(i) enforcement proceedings shall have been commenced by any Person upon such
judgment or order or (ii) there shall be any period of ten consecutive days
during which a stay of enforcement of such judgment or order, by reason of a
pending appeal or otherwise, shall not be in effect; or

            (j)   Adverse Change. There shall occur a Material Adverse Effect;
or

            (k)   Guarantor Defaults. Any Guarantor shall fail in any material
respect to perform or observe any term, covenant or agreement in the Guaranty to
which it is a party; or any Guaranty shall for any reason be partially
(including with respect to future advances) or wholly revoked or invalidated, or
otherwise cease to be in full force and effect (except in accordance


                                       66
<PAGE>   76
with its terms), or any Guarantor or any other Person shall contest in any
manner the validity or enforceability thereof or deny that it has any further
liability or obligation thereunder.

      9.02  Remedies. If any Event of Default occurs, the Agent shall, at the
request of, or may, with the consent of, the Majority Banks, (a) declare the
Commitments of each Bank to make Loans and any obligation of the Issuing Bank to
Issue Letters of Credit to be terminated, whereupon such Commitments and
obligation shall forthwith be terminated; (b) declare an amount equal to the
maximum aggregate amount that is or at any time thereafter may become available
for drawing under any outstanding Letters of Credit (whether or not any
beneficiary shall have presented, or shall be entitled at such time to present,
the drafts or other documents required to draw under such Letters of Credit) to
be immediately due and payable, and declare the unpaid principal amount of all
outstanding Loans, all interest accrued and unpaid thereon and all other amounts
payable hereunder to be immediately due and payable, without presentment,
demand, protest or other notice of any kind, all of which are hereby expressly
waived by the Company; (c) exercise all rights and remedies available to it
under the Loan Documents or applicable law; provided, however, that upon the
occurrence of any event specified in subsections 9.01(e) or (f) above (in the
case of such subsection 9.01(f) upon the expiration of the 60 day period
mentioned therein), the obligation of each Bank to make Loans and any obligation
of the Issuing Bank to Issue Letters of Credit shall automatically terminate and
the unpaid principal amount of all outstanding Loans and all interest and other
amounts as aforesaid shall automatically become due and payable without further
act of the Agent or any Bank.

      9.03  Rights Not Exclusive. The rights provided for in this Agreement and
the other Loan Documents are cumulative and are not exclusive of any other
rights, powers, privileges or remedies provided by law or in equity, or under
any other instrument, document or agreement.

                                    ARTICLE X

                                    THE AGENT

      10.01 Appointment and Authorization; "Agent." (a) Each Bank hereby
irrevocably appoints, designates and authorizes the Agent to take such action on
its behalf under the provisions of this Agreement and each other Loan Document
and to exercise such powers and perform such duties as are expressly delegated
to it by the terms of this Agreement or any other Loan Document, together with
such powers as are reasonably incidental thereto. Notwithstanding any provision
to the contrary contained elsewhere in this Agreement or in any other Loan
Document, the Agent shall not have any duties or responsibilities, except those
expressly set forth herein, or any fiduciary relationship with any Bank, and no
implied covenants, functions, responsibilities, duties, obligations or
liabilities shall be read into this Agreement or any other Loan Document or
otherwise exist against the Agent.

            (b)   The Issuing Bank shall act on behalf of the Banks with respect
to any Letters of Credit Issued by it and the documents associated therewith
until such time and except for so long as the Agent may agree at the request of
the Majority Banks to act for such Issuing


                                       67
<PAGE>   77
Bank with respect thereto; provided, however, that the Issuing Bank shall have
all of the benefits and immunities (i) provided to the Agent in this Article X
with respect to any acts taken or omissions suffered by the Issuing Bank in
connection with Letters of Credit Issued by it or proposed to be Issued by it
and the application and agreements for letters of credit pertaining to the
Letters of Credit as fully as if the term "Agent," as used in this Article X,
included the Issuing Bank with respect to such acts or omissions, and (ii) as
additionally provided in this Agreement with respect to the Issuing Bank.

            (c)   Without limiting the generality of the foregoing subsections
and notwithstanding any other provisions herein, the use of the term "agent" or
"Agent" in this Agreement with reference to the Agent is not intended to connote
any fiduciary or other implied (or express) obligations arising under agency
doctrine of any applicable law. Instead, such term is used merely as a matter of
market custom, and is intended to create or reflect only an administrative
relationship between independent contracting parties.

            (d)   The provisions of this Article X shall survive the payment of
all Obligations hereunder and inure to the benefit of BofA, including after its
resignation or replacement as the Agent, as to any actions taken or omitted to
be taken by such BofA while it was the Agent.

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

      10.03 Liability of Agent. None of the Agent, its Affiliates, or any of
their respective officers, directors, employees, agents, or attorneys-in-fact
(collectively, the "Agent-Related Persons") shall (i) be liable for any action
taken or omitted to be taken by any of them under or in connection with this
Agreement or any other Loan Document or the transactions contemplated hereby
(except for its own gross negligence or willful misconduct) or (ii) be
responsible in any manner to any of the Banks for any recital, statement,
representation or warranty made by the Company or any Subsidiary or Affiliate of
the Company or any officer thereof contained in this Agreement or in any other
Loan Document, or in any certificate, report, statement or other document
referred to or provided for in, or received by the Agent under or in connection
with, this Agreement or any other Loan Document, or the validity, effectiveness,
genuineness, enforceability or sufficiency of this Agreement or any other Loan
Document, or for any failure of the Company or any other party to any Loan
Document to perform its obligations hereunder or thereunder. No Agent-Related
Person shall be under any obligation to any Bank to ascertain or to inquire as
to the observance or performance of any of the agreements contained in, or
conditions of, this Agreement or any other Loan Document, or to inspect the
properties, books or records of the Company or any of its Subsidiaries or
Affiliates.

      10.04 Reliance by Agent.

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

            (b)   For purposes of determining compliance with the conditions
specified in Sections 5.01 and 5.02, each Bank shall be deemed to have consented
to, approved or accepted or to be satisfied with each document or other matter
required thereunder to be consented to or approved by or acceptable or
satisfactory to the Bank unless an officer of the Agent responsible for the
transactions contemplated by the Loan Documents shall have received notice from
the Bank prior to the Borrowing specifying its objection thereto and either such
objection shall not have been withdrawn by notice to the Agent to that effect or
the Bank shall not have made available to the Agent the Bank's ratable portion
of such Borrowing.

      10.05 Notice of Default. The Agent shall not be deemed to have knowledge
or notice of the occurrence of any Default or Event of Default, except with
respect to defaults in the payment of principal, interest and fees payable to
the Agent for the account of the Banks, unless the Agent shall have received
written notice from a Bank or the Company referring to this Agreement,
describing such Default or Event of Default and stating that such notice is a
"notice of default." In the event that the Agent receives such a notice, the
Agent shall give notice thereof to the Banks. The Agent shall take such action
with respect to such Default or Event of Default as shall be requested by the
Majority Banks in accordance with Article IX; provided, however, that unless and
until the Agent shall have received any such request, the Agent may (but shall
not be obligated to) take such action, or refrain from taking such action, with
respect to such Default or Event of Default as it shall deem advisable in the
best interests of the Banks.

      10.06 Credit Decision. Each Bank expressly acknowledges that none of the
Agent Related Persons has made any representation or warranty to it and that no
act by the Agent hereinafter taken, including any review of the affairs of the
Company and its Subsidiaries, shall be deemed to constitute any representation
or warranty by the Agent to any Bank. Each Bank represents to the Agent that it
has, independently and without reliance upon the Agent and based on such
documents and information as it has deemed appropriate, made its own appraisal
of and investigation into the business, prospects, operations, property,
financial and other condition and


                                       69
<PAGE>   79
creditworthiness of the Company and its Subsidiaries and made its own decision
to enter into this Agreement and extend credit to the Company hereunder. Each
Bank also represents that it will, independently and without reliance upon the
Agent and based on such documents and information as it shall deem appropriate
at the time, continue to make its own credit analysis, appraisals and decisions
in taking or not taking action under this Agreement and the other Loan
Documents, and to make such investigations as it deems necessary to inform
itself as to the business, prospects, operations, property, financial and other
condition and creditworthiness of the Company. Except for notices, reports and
other documents expressly required to be furnished to the Banks by the Agent
hereunder, the Agent shall not have any duty or responsibility to provide any
Bank with any credit or other information concerning the business, prospects,
operations, property, financial and other condition or creditworthiness of the
Company which may come into the possession of any of the Agent-Related Persons.

      10.07 Indemnification. The Banks agree to indemnify the Agent-Related
Persons (to the extent not reimbursed by or on behalf of the Company and without
limiting the obligation of the Company to do so), ratably according to the
respective amounts of their outstanding Loans, or, if no Loans are outstanding,
their Commitments, from and against any and all liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses and
disbursements of any kind whatsoever which may at any time (including at any
time following the repayment of the Loans) be imposed on, incurred by or
asserted against any such person in any way relating to or arising out of this
Agreement or any document contemplated by or referred to herein or therein or
the transactions contemplated hereby or thereby or any action taken or omitted
by any such person under or in connection with any of the foregoing; provided,
however, that no Bank shall be liable for the payment to any Agent-Related
Person of any portion of such liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements resulting
from such person's gross negligence or willful misconduct. Without limitation of
the foregoing, each Bank shall reimburse the Agent promptly upon demand for its
ratable share of any costs or out-of-pocket expenses (including fees and
expenses of counsel and the allocated cost of in-house counsel) incurred by the
Agent in connection with the preparation, execution, delivery, administration,
modification, amendment or enforcement (whether through negotiations, legal
proceedings or otherwise) of, or legal advice in respect of rights or
responsibilities under, this Agreement, any other Loan Document, or any document
contemplated by or referred to herein to the extent that the Agent is not
reimbursed for such expenses by or on behalf of the Company.

      10.08 Agent in Individual Capacity. BofA and its Affiliates may make loans
to, issue letters of credit for the account of, accept deposits from, acquire
equity interests in and generally engage in any kind of banking, trust,
financial advisory, underwriting or other business with the Company and its
Subsidiaries and Affiliates as though BofA were not the Agent or the Issuing
Bank hereunder and without notice to or consent of the Banks. The Banks
acknowledge that, pursuant to such activities, BofA or is Affiliates may receive
information regarding the Company or its Affiliates (including information that
may be subject to confidentiality obligations in favor of the Company or such
Subsidiary) and acknowledge that the Agent shall be under no obligation to
provide such information to them. With respect to its Loans, BofA shall


                                       70
<PAGE>   80
have the same rights and powers under this Agreement as any other Bank and may
exercise the same as though it were not the Agent or the Issuing Bank.

      10.09 Successor Agent. The Agent may, and at the request of the Majority
Banks shall, reign as Agent upon 30 days' notice to the Banks. If the Agent
shall resign as Agent under this Agreement, the Majority Banks, after consulting
with the Company, shall appoint from among the Banks a successor agent for the
Banks. If no successor Agent is appointed prior to the effective date of the
resignation of the Agent, the Agent shall appoint, after consulting with the
Banks and the Company, a successor agent from among the Banks. Upon the
acceptance of its appointment as successor agent hereunder, such successor agent
shall succeed to all the rights, powers and duties of the retiring Agent and the
term "Agent" shall mean such successor agent and the retiring Agent's rights,
powers and duties as Agent shall be terminated. After any retiring Agent's
resignation hereunder as Agent, the provisions of this Article X and Sections
11.04 and 11.05 shall inure to its benefit as to any actions taken or omitted to
be taken by it while it was Agent under this Agreement. Notwithstanding the
foregoing, however, BofA may not be removed as the Agent at the request of the
Majority Banks unless BofA shall also simultaneously be replaced as "Issuing
Bank" hereunder pursuant to, documentation in form and substance reasonably
satisfactory to BofA.

                                   ARTICLE XI

                                  MISCELLANEOUS

      11.01 Amendments and Waivers. No amendment or waiver of any provision of
this Agreement or any other Loan Document and no consent with respect to any
departure by the Company therefrom, shall be effective unless the same shall be
in writing and signed by the Majority Banks, and then such waiver shall be
effective only in the specific instance and for the specific purpose for which
given; provided, however, that no such waiver, amendment, or consent shall,
unless in writing and signed by all the Banks do any of the following:

            (a)   increase the Commitment of any Bank or subject any Bank to any
additional obligations;

            (b)   postpone or delay any date fixed for any payment of principal,
interest or (subject to clause (iii) below) fees or other amounts due hereunder
or under any Loan Document;

            (c)   reduce the principal of, or the rate of interest specified
herein on any Loan, or (subject to clause (iii) below) of any fees or other
amounts payable hereunder or under any Loan Document;

            (d)   change the percentage of the Commitments or of the aggregate
unpaid principal amount of the Loans which shall be required for the Banks or
any of them to take any action hereunder; or

            (e)   release any Guarantor from its obligations under its Guaranty;
or


                                       71
<PAGE>   81
            (f)   amend this Section 11.01 or Section 2.13;

and, provided further, that (i) no amendment, waiver or consent shall, unless in
writing and signed by the Issuing Bank in addition to the Majority Banks or all
the Banks, as the case may be, affect the rights or duties of the Issuing Bank
under this Agreement or any L/C-Related Document relating to any Letter of
Credit issued or to be issued by it, (ii) no amendment, waiver or consent shall,
unless in writing and signed by the Agent in addition to the Majority Banks,
affect the rights or duties of the Agent under this Agreement, and (iii) the Fee
Letter may be amended, or rights or privileges thereunder waived, in a writing
executed by the parties thereto.

      11.02 Notices.

            (a)   All notices, requests and other communications provided for
hereunder shall be in writing (including telegraphic, telex, facsimile
transmission or cable communication) and mailed, telegraphed, telexed or
delivered, if to the Company to its address specified on Schedule 11.02 hereof;
if to any Bank, to its Domestic Lending Office set forth on Schedule 11.02; and
if to the Agent, to its address specified on Schedule 11.02 hereof; or, as to
the Company or the Agent, to such other address as shall be designated by such
party in a written notice to the other parties, and as to each other party at
such other address as shall be designated by such party in a written notice to

"Issuing Bank" on the applicable signature page hereof.

            (b)   Any agreement of the Agent or the Banks to receive certain
notices by telephone or facsimile is solely for the convenience and at the
request of the Company. The Agent and the Banks shall be entitled to rely on the
authority of any Person purporting to be a Person authorized by the Company to
give such notice and the Agent and the Banks shall not have any liability to the
Company or other Person on account of any action taken or not taken by the Agent
or any Bank in reliance upon such telephonic or facsimile notice. The obligation
of the Company to repay the Loans and L/C Obligations shall not be affected in
any way or to any extent by any failure by the Agent or any Bank to receive
written confirmation of any telephonic or facsimile notice or the receipt by the
Agent and the Banks of a confirmation which is at variance with the terms
understood by the Agent and the Banks to be contained in the telephonic or
facsimile notice.

      11.03 No Waiver; Cumulative Remedies. No failure to exercise and no delay
in exercising, on the part of any Agent or any Bank, any right, remedy, power or
privilege hereunder, shall operate as a waiver thereof; nor shall any single or
partial exercise of any right, remedy, power or privilege hereunder preclude any
other or further exercise thereof or the exercise of any other right, remedy,
power or privilege.


                                       72

            (a)   pay or reimburse the Agent on demand for all reasonable costs
and expenses incurred in connection with the development, preparation, delivery,
administration and execution of, and any amendment, supplement, waiver or
modification to, this Agreement, any Loan Document and any other documents
prepared in connection herewith or therewith, and the consummation of the
transactions contemplated hereby and thereby, including the reasonable costs and
expenses of counsel to the Agent (and the allocated cost of internal counsel)
with respect thereto;

            (b)   pay or reimburse each Bank and the Agent on demand for all
costs and expenses incurred by them in connection with the enforcement or
preservation of any rights (including in connection with any "workout" or
restructuring regarding the Loans) under this Agreement, any Loan Document, and
any such other documents, including fees and out-of-pocket expenses of counsel
(and the allocated cost of internal counsel) to the Agent and to each of the
Banks; and

            (c)   pay or reimburse the Agent on demand for all appraisal, audit,

Agent-Related Persons, and each Bank and each of their respective officers,
directors, employees, counsel, agents and attorneys-in-fact (each, an
"Indemnified Person") harmless from and against any and all liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
charges, expenses or disbursements (including reasonable fees and expenses of
counsel and allocated costs of internal counsel) of any kind or nature
whatsoever which may at any time be imposed on, incurred by or asserted against
any such Indemnified Person in any way relating to or arising out of this
Agreement or any document contemplated by or referred to herein, or the
transactions contemplated hereby, or any action taken or omitted by any such
Indemnified Person under or in connection with any of the foregoing, including
with respect to any investigation, litigation or proceeding related to this
Agreement or the Loans or the Letters of Credit or the use of the proceeds
thereof (whether or not any Indemnified Person is a party thereto) (all the
foregoing, collectively, the "Indemnified Liabilities"); provided, that the
Company shall have no obligation hereunder to any Indemnified Person with
respect to Indemnified Liabilities arising from the gross negligence or willful
misconduct of such Indemnified Person. The agreements in this section shall
survive payment of all other Obligations.

      11.06 Successors and Assigns. The provisions of this Agreement shall be
binding upon and inure to the benefit of the parties hereto and their respective
successors and assigns, subject to Section 11.07, except that the Company may

                                       73
<PAGE>   83
      11.07 Assignments, Participations etc.

            (a)   Any Bank may, with the written consent of the Company and the
Agent and the Issuing Bank, which consents shall not be unreasonably withheld,
at any time assign and delegate to one or more Eligible Assignees (each an
"Assignee") all or any ratable part of the Aggregate Commitment and of the
entire Aggregate Revolving Commitment, Aggregate Term Commitment and Aggregate
L/C Commitment or any other rights or obligations of such Bank hereunder in a
minimum amount of $10,000,000 or, if less, 100% of such Bank's Commitments;
provided, however, that with the consent of the Agent and the Issuing Bank
(which shall not be unreasonably withheld) but without the consent of the
Company, any Bank may assign all or any ratable part of the Aggregate Commitment
and of the entire Aggregate Revolving Commitment, Aggregate Term Commitment and
Aggregate L/C Commitment or any other rights or obligations of such Bank
hereunder in a minimum amount of $10,000,000, or, if less 100% of such Bank's
Commitments, to any entity described in subsection (iii) of the definition of
Eligible Assignee (together with the foregoing defined Assignees, "Assignees");
provided further, however, that the Company, the Issuing Bank and the Agent may
continue to deal solely and directly with such Bank in connection with the
interests so assigned to an Assignee until (i) written notice of such
assignment, together with payment instructions, addresses and related
information with respect to the Assignee, shall have been given to the Company
and the Agent by such Bank and the Assignee, (ii) such Bank and its Assignee
shall have delivered to the Company, the Issuing Bank and the Agent an
Assignment and Acceptance in the form of Exhibit G ("Assignment and Acceptance")
and (iii) the processing fee of $3,500 shall have been paid to the Agent.

            (b)   From and after the date that the Agent notifies the assignor
Bank that it has received the Assignment and Acceptance, (i) the Assignee
thereunder shall be a party hereto and, to the extent that rights and
obligations hereunder have been assigned to it pursuant to such Assignment and
Acceptance, shall have the rights and obligations of a Bank under the Loan
Documents and (ii) the assignor Bank shall, to the extent that rights and
obligations hereunder have been assigned by it pursuant to such Assignment and
Acceptance, relinquish its rights and be released from its obligations under the
Loan Documents.

            (c)   Immediately upon each Assignee's making its payment under the
Assignment and Acceptance, this Agreement, shall be deemed to be amended to the
extent, but only to the extent, necessary to reflect the addition of the
Assignee and the resulting adjustment of the Commitments arising therefrom. The
Commitment allocated to each Assignee shall reduce such Commitments of the
assigning Bank pro tanto.

            (d)   Any Bank may at any time sell to one or more banks or other
entities (a "Participant") participating interests in all or any ratable part of
the Loans and the entire Commitment of that Bank or any other interest of that
Bank hereunder; provided, however, that (i) the Bank's obligations under this
Agreement shall remain unchanged, (ii) the Bank shall remain solely responsible
for the performance of such obligations, (iii) the Company and the Agent shall
continue to deal solely and directly with the Bank in connection with the Bank's
rights and obligations under this Agreement, and (iv) no Bank shall transfer or
grant any participating interest under which the Participant shall have rights
to approve any amendment to,


                                       74
<PAGE>   84
or any consent or waiver with respect to this Agreement except to the extent
such amendment, consent or waiver would require unanimous consent as described
in the first proviso to Section 11.01. In the case of any such participation,
the Participant shall not have any rights under this Agreement, or any of the
other Loan Documents, and all amounts payable by the Company hereunder shall be
determined as if such Bank had not sold such participation, except that if
amounts outstanding under this Agreement are due and unpaid, or shall have been
declared or shall have become due and payable upon the occurrence of an Event of
Default, each Participant shall be deemed to have the right of set-off in
respect of its participating interest in amounts owing under this Agreement to
the same extent as if the amount of its participating interest were owing
directly to it as a Bank under this Agreement.

            (e)   Notwithstanding any other provision in this Agreement, any
Bank may at any time create a security interest in, or pledge, all or any
portion of its rights under and interest in this Agreement in favor of any
Federal Reserve Bank in accordance with Regulation A of the FRB or U.S. Treasury
Regulation 31 CFR Section 203.14, and such Federal Reserve Bank may enforce such
pledge or security interest in any manner permitted under applicable law.

      11.08 Set-off; Payments Set Aside.

            (a)   In addition to any rights and remedies of the Banks provided
by law, if an Event of Default exists, each Bank is authorized at any time and
from time to time, without prior notice to the Company, any such notice being
waived by the Company to the fullest extent permitted by law, to set-off and
apply any and all deposits (general or special, time or demand, provisional or
final) at any time held and other indebtedness at any time owing by such Bank to
or for the credit or the account of the Company against any and all obligations
of the Company now or hereafter existing under this Agreement or any other Loan
Document and any Loan held by such Bank irrespective of whether or not the Agent
or such Bank shall have made demand under this Agreement or any Loan Document
and although such obligations may be contingent or unmatured. Each Bank agrees
promptly to notify the Company and the Agent after any such set-off and
application made by such Bank; provided, however, that the failure to give such
notice shall not affect the validity of such set-off and application. The rights
of each Bank under this Section 11.08(a) are in addition to the other rights and
remedies (including without limitation, other rights of set-off) which the Bank
may have.

            (b)   To the extent that the Company or any Guarantor makes a
payment to the Agent or the Banks, or the Agent or any Bank exercises its right
of set-off, and such payment or the proceeds of such set-off or any part thereof
are subsequently invalidated, declared to be fraudulent or preferential, set
aside or required (including pursuant to any settlement entered into by the
Agent or such Bank in its discretion) to be repaid to a trustee, receiver or any
other party, in connection with any Insolvency Proceeding or otherwise, then (i)

survives the termination of the "Aggregate Commitments" or repayment of other
"Obligations" under the Prior Credit Agreement, including the Company's
obligations (if any) under Articles IV and X and Sections 11.04 and 11.05, shall
survive the execution and effectiveness of this Agreement.

ENVIRONMENTAL

Granite Construction in the normal course of business utilizes petroleum
(hydrocarbon) products which by definition are considered hazardous materials.
The utilization of these asphalt products, diesel, and gasoline over the years
of operations have 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.

cash while maintaining liquidity and working funds for the present and future
operations.

In order to provide control of all investments and cash, this policy shall limit
investment activities to: first, preserve principal; second, meet liquidity
needs; third, avoid inappropriate concentration of investments; and fourth,
deliver good yield in relationship to these GUIDELINES and market conditions.

DURATION

Cash investments are restricted to the average duration of one (1) year from
date of settlement. Any investments with longer maturity than one year must be
invested in instruments issued by, guaranteed by, or insured by the U.S.
Government or any of its agencies. The average portfolio duration of escrows and
deposit agreements shall not exceed five (5) years. Short term investments shall
be defined as instruments maturing in ninety-one (91) days or more.

LIQUIDITY

The duration of the portfolio including escrows & deposits shall be consistent
with the cash needs as determined by the cash forecast. The portfolio will be
constructed in order to provide funds that will enable the company to meet its
day to day requirements and short term needs. Any excess cash above the
aforementioned requirements may be invested in instruments with longer maturity.

MARKETABILITY

Holdings should be of sufficient size and held in issues which are traded
actively (except time deposits, loan participation, and master notes) to
facilitate transactions at a minimum cost and accurate market valuation.

OBJECTIVES

The assets are liquidity and working funds for the present and future operations
of the firm. It is essential that the assets be invested in a high quality
portfolio which: first, preserve principal; second, meet liquidity needs; third,
delivers good yield in relationship to these guidelines and market conditions;
fourth, avoids inappropriate concentrations of investments; and fifth, provides
fiduciary control of all investments and cash by the firm's appointed custodian.

DURATION

The portfolio's average duration shall not exceed two (2) years from date of
settlement. Short term investments shall be defined as instruments maturing in
ninety-one (91) days or more.

LIQUIDITY

The portfolio will be constructed so that it can provide $ 1,000,000.00 in 30
days and the remainder shall be consistent with the cash needs of the Company as
determined by the cash forecast, and be so constructed that it can provide funds
to match the Company's cash requirements.

MARKETABILITY

Holdings should be of sufficient size and held in issues which are traded
actively (except time deposits, loan participation, and master notes) to
facilitate transactions at a minimum cost and accurate market valuation.

TRADING

All purchases and sales will be executed at the best net price with the
principal dealers and banks in the particular securities. All securities
purchased will be in the name of client.

B.      AGREEMENT

        In consideration of Bank issuing for the account of Customer the Letter
of Credit, Customer agrees to the following:

        1. Customer shall pay Bank, on demand, all amounts paid by Bank under or
in respect of the Letter of Credit.

        2. On each fee payment date, so long as any undrawn amount of the Letter
of Credit remains available, Customer shall pay Bank a Letter of Credit fee. The
fee payment dates shall be the dates as Customer and Bank may agree, or in the
absence of such agreement, the fee payment date shall be the date on which the
Bank issues such Letter of Credit. The fee shall be at such rate per annum as
Customer and Bank may agree, or in the absence of such agreement, at the rate
customarily charged by Bank at the time such fee is payable. The applicable
Letter of Credit fee shall be calculated and payable on the undrawn amount of
the Letter of Credit as of such fee payment date, and shall be for the period
commencing on such fee payment date and ending on the day preceding the next fee
payment date (or the expiration date of the Letter of Credit, as the case may
be), both dates inclusive. The Letter of Credit fee will be computed on the
basis of a 365 day year and actual days elapsed. Bank shall not be required to
refund any portion of the Letter of Credit fee paid for any period during which
(a) the Letter of Credit expires of otherwise terminates, or (b) the undrawn
amount of the Letter of Credit is reduced by drawings or by amendment.

        3. Customer shall pay Bank, on demand, commissions and fees for
amendments to the Letter of Credit, payments under the Letter of Credit,
extensions of the Letter of Credit, cancellation of the Letter of Credit, and
other services in the amounts Customer and Bank may agree, or, in the absence of
such agreement, in the amounts customarily charged by Bank on the date of Bank's
demand.

        4. All payments and deposits by Customer under this Application and
Agreement shall be made at the branch or office Bank may designate from time to
time. Bank shall have no obligation to pay Customer interest on any deposit made
by Customer under this Application and Agreement.

        5. (a) All payments and deposits by Customer under this Application and
Agreement shall be in the currency in which the Letter of Credit is payable
except that Bank may, at its option, require payments and deposits by Customer
under this Application and Agreement to be made in U.S. Dollars if the Letter of
Credit is payable in a foreign currency.

            (b) The amount of each payment and each deposit by Customer under
this Application and Agreement in U.S. Dollars for a Letter of Credit payable in
a foreign currency shall be determined by converting the relevant amount to U.S.
Dollars at the Conversion Rate in effect:

                 (i) with respect to each payment under Paragraph B.1., on the
date the payment is made by Bank under or in respect of the Letter of Credit;
and

                 (ii) with respect to each payment not falling under the
preceding clause (i) and each deposit, on the date of Bank's demand for such
payment or deposit.

            (c) If a U.S. Dollar deposit by Customer under this Application and
Agreement for a Letter of Credit payable in a foreign currency becomes less than
the U.S. Dollar equivalent of the undrawn amount of the Letter of Credit because
of any variation in rates of exchange, Customer shall deposit with Bank, on
demand, additional amounts in U.S. Dollars so that the total amount deposited by
Customer under this Application and Agreement is not less than the U.S. Dollar
equivalent of the undrawn amount of the Letter of Credit, determined by using
the Conversion Rate on the date of Bank's latest demand.

            (d) "Conversion Rate" means the rate quoted by Bank in San
Francisco, California for the purchase from Bank of the relevant foreign
currency with U.S. Dollars.

        6. Customer shall reimburse or compensate Bank, on demand, for all costs
incurred, losses suffered and payments made by Bank which are applied or
allocated by Bank to the Letter of Credit (as determined by Bank) by reason of
any and all present or future reserve, deposit, assessment or similar
requirements against (or against any class of or change in or in the amount of )
assets or liabilities of, or commitments or extensions of credit by, Bank.

        7. If Bank determines that any law, rule, regulation or guideline
regarding capital adequacy affects or would affect the amount of capital
required to be maintained by Bank or any corporation controlling Bank and that
(taking into consideration Bank's policies with respect to capital adequacy and
Bank's desired return on capital) the amount of required capital is increased as
a result of Bank's obligations under the Letter of Credit, then, on demand,
Customer shall pay Bank additional amounts sufficient as specified by Bank to
compensate Bank for such increase.

        8. Upon the occurrence of any of the following events, Customer shall
deposit with Bank, on demand and as cash security for Customer's obligations to
Bank under this Application and Agreement, an amount equal to the undrawn amount
of the Letter of Credit:

            (a) Customer defaults under any provision of this Application and
Agreement;

            (b) Any bankruptcy or similar proceeding is commenced with respect
to Customer;

            (c) Any default occurs under any other agreement involving the
borrowing of money or the extension of credit under which Customer may be
obligated as borrower, instalment purchaser or guarantor, if such default
consists of the failure to pay any indebtedness when due or if such default
permits or causes the acceleration of any indebtedness or the termination of any
commitment to lend or to extend credit;

            (d) Customer defaults on any other obligation to Bank;

            (e) In the opinion of Bank, any material adverse change occurs in
Customer's business, operations, financial condition or ability to perform its
obligations under this Applications and Agreement;

            (f) Any court order, injunction or other legal process is issued
restraining or seeking to restrain drawing or payment under the Letter of
Credit,

            (g) Any person other than Beneficiary attempts, or in any way claims
any right, to draw under the Letter of Credit, including, without limitation,
any debtor in possession, custodian, receiver, trustee, assignee for benefit of
creditors, personal representative or other successor.

        9. Customer shall pay interest, on demand, on any amount not paid when
due under this Application and Agreement from the due date until payment in full
at a rate per annum equal to the rate of interest publicly announced from time
to time by Bank in San Francisco, California, as its reference rate plus three
percentage points. The reference rate is set by Bank based on various factors
including Bank's costs and desired return, general economic conditions and other
factors, and is used as a reference point for pricing some credits. Bank may
price credit at, above or below the reference rate. Any change in Bank's
reference rate shall take effect at the opening of business on the day specified
in Bank's public announcement of change in Bank's reference rate. Interest will
be computed on the basis of a 365 day year and actual days elapsed.

        10. Customer authorizes Bank to charge any of Customer's accounts with
Bank for all amounts then due and payable to Bank under this Application and
Agreement.

        11. Customer shall pay, on demand, all costs, expenses and attorney's
fees (including allocated costs for in-house legal services) incurred by Bank in
connection with (a) any dispute concerning the Letter of Credit or this
Application and Agreement, or (b) the enforcement of this Application and
Agreement.

        12. If any arbitration award, judgment or orders is given or made for
the payment of any amount due under this Application and Agreement and such
arbitration award, judgment or order is expressed in a currency other than the
currency required under this Application and Agreement, Customer shall indemnify
Bank against and hold Bank harmless from all lost and damage incurred by Bank as
a result of any variation in rates of exchange between the date of such
arbitration award, judgment or order and the date of payment (or ii) the case of
partial payments, the date of each partial payment) thereof. This indemnity
shall constitute an obligation separate and independent from the other
obligations contained in this Applications and Agreement, shall give rise to a
separate and independent cause of action, shall apply irrespective of any
indulgence granted by Bank form time to time, and shall continue in full force
and effect notwithstanding any arbitration award, judgment or order for a
liquidated sum respect of an amount due under this Application and Agreement.

        13. The word "Customer" in this Application and Agreement refers to each
signer (other than Bank) of this Application and Agreement. If this Application
and Agreement is signed by more than one Customer, their obligations under this
Application and Agreement shall be joint and several.

        14. Subject to the laws, customs and practices of the trade in the area
where the beneficiary is located, the Letter of Credit will be subject to, and
performance under the Letter of Credit by Bank, its correspondents, and the
beneficiary will be governed by, the "Uniform Customs and Practice for
Documentary Credits (1993 Revision), International Chamber of Commerce,
Publication No. 500", or by later Uniform Customs and Practice fixed by later
Congresses of the International Chamber of Commerce as in effect on the date the
Letter of Credit is issued.

        15. This Application and Agreement shall be governed by and construed
under the laws of the State of California, to the jurisdiction of which the
parties hereto submit.

        16. Any controversy among the parties arising out of or relating to this
Application and Agreement or the Letter of Credit shall at the request of any
party be determined by arbitration. The arbitration shall be conducted in San
Francisco, California, under the United States Arbitration Act (Title 9, U.S.
Code), notwithstanding any choice of law provision in this Application and
Agreement or the Letter of Credit, and pursuant to the Commercial Rules of the
American Arbitration Association. The arbitrator shall give effect to statutes
of limitation in determining any claim. Any controversy concerning whether an
issue is arbitrable shall be determined by the arbitrator. Judgment upon the
arbitration award may be entered in any court having jurisdiction. This
Paragraph shall not limit the right of any party to this Application and
Agreement or the Letter of Credit to exercise lawful self-help remedies or to
obtain provisional or ancillary remedies from a court of competent jurisdiction
before, during, or after the pendency of any arbitration. The seeking, obtaining
or exercising of such a remedy does not waive the right of any party, including
the party who sought such remedy, to resort to arbitration. Notwithstanding the
foregoing, no controversy shall be submitted to arbitration under this Paragraph
without the consent of all parties if, at the time of the proposed submission,
such controversy arises from or relates to an obligation to Bank which is
secured by real property collateral.

        17. Customer represents and warrants to Bank that Customer has obtained
all import and export licenses and other governmental approvals required for the
goods and the documents described in the Letter of Credit. Without limiting the
generality of the foregoing, Customer further expressly represents and warrants
to Bank that the transactions underlying the Letter of Credit are not prohibited
under the Foreign Assets Control Regulations of the United States Treasury
Department.

This Application and Agreement is executed by Customer on______________, 19___.

Bank of America National Trust and Savings Association, 
     for itself and as Agent 
     for the Banks from time to time
     party to the Credit Agreement, referred to below
555 California Street, 41st Floor
Credit Products 3838
San Francisco, CA 94104

Ladies and Gentlemen:

      I have acted as counsel for Granite Construction Incorporated, a Delaware
corporation ("Borrower"), in connection with that certain Credit Agreement dated
as of June 30, 1997 including Exhibits and Schedules (the "Credit Agreement"),
by and among Borrower, the several financial institutions parties to the Credit
Agreement (the "Banks") and Bank of America National Trust and Savings
Association as agent for the Banks (the "Agent") and as issuing bank. I have
also represented each of Granite Construction Company, a California corporation
("GCC"), Granite SR91 Corporation, a California corporation ("SR91"), Wilcott
Corporation, a Colorado corporation ("Wilcott"), Desert Aggregates, Inc., a
California corporation ("Desert"), G.G. & R., Inc., a Utah corporation ("G.G. &
R."), Intermountain Slurry Seal, Inc., a Utah corporation ("Intermountain"),
Bear River Contractors, a Wyoming corporation ("Bear River"), Pozzolan Products
Company ("P.P.C."), a Utah corporation ("Pozzolan"), GTC, Inc., a Texas
corporation ("GTC"), GILC, L.P., a California limited partnership ("GILC,
L.P."), SR91, L.P., a California limited partnership ("SR91, L.P.") and GILC
Incorporated, a California corporation ("GILC", and together with GCC SR91,
Desert, Wilcott, G.G. & R., Intermountain, Bear River, GILC, L.P., SR91, L.P.,
Pozzolan and GTC, the "Subsidiaries"), each of which is a direct or indirect
wholly owned subsidiary of Borrower, in connection with the Guaranty given by
each of the Subsidiaries in favor of the Agent for the benefit of Banks
guaranteeing the obligations of Borrower under the Credit

Bank of America National Trust and Savings Association,

Agreement. I am rendering this opinion pursuant to subsection 5.01 (c) of the
Credit Agreement. Except as otherwise defined herein, capitalized terms used but
not defined herein shall have the meanings given to them in the Credit
Agreement.

        As used herein, the term "Loan Documents" shall mean the Credit
Agreement and the Guaranty.

        I am admitted to practice law only in the State of California, and I
express no opinion concerning any law other than the law of the State of
California, the Delaware General Corporation law, the law of the United States
of America, and, to the extent necessary to render my opinion in paragraphs
1(b), 1(d), 1(e), l(f), the second sentence of paragraph 3 and paragraphs 5(d),
6 and 8, the Colorado Corporations Code, the Utah Revised Business Corporations
Act, the Wyoming Business Corporations Act and the Texas Business Corporation
Act. In so far as the opinions contained herein purport to relate to the
Delaware General Corporation Law, the Colorado Corporations Code, the Utah
Revised Business Corporations Act, the Wyoming Business Corporations Act and the
Texas Business Corporation Act (collectively, the "Laws"), I have relied on such
Laws as reported in standard compilations.

        In rendering this Opinion, I have assumed the genuineness and
authenticity of all signatures (other than that of Borrower and each Subsidiary)
on original documents; the authenticity of all documents submitted to me as
originals; the conformity of originals to all documents submitted to me as
copies; the accuracy, completeness and authenticity of certificates of public
officials; the due authorization, execution and delivery of all documents
(except the due authorization, execution and delivery by Borrower of the Credit
Agreement and by each Subsidiary of the Guaranty) where authorization,
execution and delivery are prerequisites to the effectiveness of such documents;
the power and authority of the Banks to enter into and perform their obligations
under the Loan Documents; that the Banks are duly qualified in the State of
California to do business of the type contemplated by the Loan Documents; that
each of the Banks qualifies for the exemption from the otherwise applicable
interest rate limitations of California law for loans or forbearances by, as the
case may be, (i) national banks provided by Article XV, Section 1 of the
California Constitution or (ii) certain "foreign (other nation) banks" provided
by California Financial Code Section 1716 or (iii) state banks provided by
Article XV, Section 1 of the California Constitution; that all loans under me
Credit Agreement will be made by the Banks for their own accounts or for the
account of another person or entity that qualifies for an exemption hunk me
interest rate limitations of California law, and there is no present agreement
or plan, express or implied, on the part of the Banks to sell participations or
any other interest in the loans to be made under the Credit Agreement to any
person or entity other than a person or entity that also qualifies for an
exemption. From the interest rate limitations of California law; and with


<PAGE>   134
Bank of America National Trust and Savings Association, 
for itself and as Agent 
June 30, 1997
Page 3

respect to matters of fact (as distinguished from matters of law), I also have
relied upon and assumed that the representations of the Borrower and each
Subsidiary and the other parties set forth in the Loan Documents and any other
certificates, instruments or agreements executed in connection therewith or
delivered to me are true, correct, complete and not misleading, although to my
knowledge the representations of the Borrower and each Subsidiary set forth in
the Loan Documents and any such other certificates, instruments and agreements
ant true, correct, complete and not misleading. I have also assumed that all
individuals executing and delivering documents on behalf of the Banks and Agent
had the legal capacity to so execute and deliver and that the Loan Documents are
obligations binding upon Banks and Agent.

        With respect to my opinions in paragraph 4(c) and 5(c) below, I have
relied solely upon copies, supplied to me by the Borrower or a Subsidiary, of
each undertaking, contract, indenture, mortgage, deed. of trust or other
instrument document or agreement listed in Exhibit A, (i) of the Borrower listed
on the Index to Form 10K Exhibits to the Borrower's Annual Report on Form 10K
for the fiscal year ending December 31, 1996 and (ii) of the Borrower involving
amounts in excess of $50,000,000 to which Borrower or any Subsidiary is a party
or by which Borrower or any Subsidiary is bound.

        In rendering my opinion in paragraph 6, I have relied solely on a
certificate of good standing from each of the Secretary of State's office of
each of the states listed below the Borrower's and each Subsidiary's name on
Exhibit B.

        Where I render an opinion "to the best of my knowledge" or concerning an
item "known to me" or my opinion otherwise refers to my "knowledge," it is
intended to indicate that during the course of my representation of Borrower and
the Subsidiaries, no information that would give me current actual knowledge of
the inaccuracy of such statement has come to my attention in rendering legal
services to Borrower or the Subsidiaries.

        On the basis of the foregoing, in reliance thereon, and with the
foregoing qualifications, I am of the opinion that:

        1. (a) Borrower is a corporation, duly incorporated and validly existing
under the laws of Delaware and has the requisite corporate power and authority
to own its property and to conduct the business in which it is currently
engaged. (b) Wilcott is a corporation duly incorporated and validly existing
under the laws of Colorado and has the requisite corporate power and authority
to own its property and to conduct the business in which it is currently
engaged. (c) Each of GCC, SR91, GILC and Desert is a corporation duly
incorporated and



<PAGE>   135
Bank of America National Trust and Savings Association, 
for itself and as Agent 
June 30, 1997
Page 4


validly existing under the laws of California and has the requisite corporate
power and authority to own its property and to conduct the business in which it
is currently engaged. (d) Each of G.G. & R., Intermountain, and Pozzolan is a
corporation duly incorporated and validly existing under the laws of Utah and
has the requisite corporate power and authority to own its property and to
conduct the business in which it is currently engaged. (e) Bear River is a
corporation duly incorporated and validly existing under the laws of Wyoming and
has the requisite corporate power and authority to own its property and to
conduct the business in which it is currently engaged. (f) GTC is a corporation
duly incorporated and validly existing under the laws of Texas and has the
requisite corporate power and authority to own its property and to conduct the
business in which it is currently engaged. (g) GILC, L.P. and SR91, L.P. are
California limited partnerships validly existing under the laws of California
and each has the requisite partnership power and authority to own its property
and to conduct the business in which it is currently engaged.

        2. Borrower (a) has taken all necessary and appropriate corporate action
to authorize the execution, delivery and performance of the Credit Agreement,
and (b) has the corporate power and authority to execute, deliver and perform
the Credit Agreement. Each Subsidiary (a) has taken all necessary and
appropriate corporate action or partnership action, as applicable, to authorize
the execution, delivery and performance of the Guaranty, and (b) has the
corporate power or partnership power, as applicable, and authority to execute,
deliver and perform the Guaranty.

        3. The Credit Agreement has been duly executed and delivered by the
Borrower. The Guaranty has been duly executed and delivered by each of the
Subsidiaries. The Credit Agreement constitutes a legal, valid and binding
obligation of Borrower, enforceable against Borrower in accordance with its
terms. The Guaranty constitutes a legal, valid and binding obligation of each
Subsidiary, enforceable against each Subsidiary in accordance with its terms.

        4. The execution, delivery and performance by Borrower of the Credit
Agreement do not (a) violate or contravene any injunction, order, writ,
judgment, decree, determination or award of any United States or California
Governmental Authority as presently in effect applicable to Borrower; (b)
conflict with or result in a breach of or constitute a default under the
certificate of incorporation and bylaws of Borrower; (c) violate or result in a
breach of or constitute any default under any agreements of Borrower set forth

order, decree or undertaking as presently in effect or any such agreements of

        5. The execution, delivery and performance by each Subsidiary of the
Guaranty do not (a) violate or contravene any injunction, order, writ judgment,
decree, determination or award of any United States or California Governmental
Authority as presently in effect applicable to each Subsidiary; (b) conflict
with or result in a breach of or constitute a default under the
articles/certificates of incorporation and bylaws or partnership agreement, as
applicable, of each Subsidiary; (c) violate or result in a breach of or
constitute any default under any agreements of each Subsidiary set forth in
Exhibit A, and do not result in or require the creation or imposition of any
lien on any Subsidiary's its properties or revenues pursuant to any injunction,
order, decree or undertaking as presently in effect or any such agreements of
each Subsidiary; or (d) result in or require the creation or imposition of any
lien on any of its properties or revenues pursuant to any provision of any law,
rule or regulation as presently in effect.

        6. Each of Borrower, and the Subsidiaries is duly qualified to do
business and is in good standing in the states listed below its name on Exhibit
B hereto.

        7. No authorization, consent, approval, license, qualification or formal
exemption from, nor notice to, nor any filing, recordation, declaration or
registration with, any United States or California Governmental Authority, or to
my knowledge any other Governmental Authority, is necessary or required on the
part of Borrower in connection with the execution, delivery, or performance by
Borrower of the Credit Agreement.

        8. No authorization, consent, approval, license, qualification or formal
exemption from, nor notice to, nor any filing, recordation, declaration or
registration with any United States or California Governmental Authority, or to
my knowledge any other Governmental Authority, is necessary or required on the
part of each Subsidiary in connection with the execution, delivery, or
performance by each Subsidiary of the Guaranty.

        9. To the best of my knowledge, there is no claim, dispute, injunction,
temporary restraining order, action, litigation, investigation or proceeding
pending or threatened against Borrower before any court, arbitrator,
administrative agency or Governmental Authority of any kind (a) with respect to
the Credit Agreement or (b) which, if adversely determined, would have a
Material Adverse Effect.

        10. To the best of my knowledge, there is no claim, dispute, injunction,
temporary restraining order, action, litigation, investigation or proceeding
pending or threatened against any Subsidiary before any court, arbitrator,
administrative agency or Governmental Authority of any kind (a) with respect to
the Guaranty or (b) which, if adversely determined, would have a Material

        11. Neither the Borrower nor any Subsidiary is an "investment company"
or a company "controlled" by an "investment company," within the meaning of the
Investment Company Act of 1940, as amended. Neither the Borrower nor any
Subsidiary is subject to regulation under the Public Utility Holding Company Act
of 1935, the Interstate Commerce Act (49 U.S.C Sections 10101 et seq. (Supp.
1992) or the Federal Power Act which would limit its ability to incur
Indebtedness.

        12. Neither the Borrower nor any Subsidiary is generally engaged in the
business of purchasing or selling Margin Stock or extending credit for the
purpose of purchasing or carrying Margin Stock. The aggregate value of all
Margin Stock directly or indirectly owned by the Borrower and its Subsidiaries
is less than 25% of the aggregate value of the consolidated assets of the
Borrower and its Subsidiaries.

        13. The only subsidiaries of Borrower are the Subsidiaries and Granite
SR91 L.P. a limited partnership, of which Granite SR91 Corporation is the
general partner and the Borrower is the sole limited partner.

        The opinions expressed in this letter are qualified to the extent that
the validity, binding nature or enforceability of any provisions of the Loan
Documents may be limited or otherwise affected by:

        a. The effects of bankruptcy, insolvency, reorganization, fraudulent
conveyance, moratorium, or other similar laws now or hereafter in effect
limiting the validity or enforceability of creditor's rights and remedies
generally;

        b. General principles of equity, regardless of whether considered in
proceedings in equity or at law;

        c. The covenant of good faith and fair dealing implied in every 
agreement under common law (and to similar provisions of federal law, where
applicable); and

        d. The effect of any law or legal principle which provides that a court
may refuse to enforce, or may limit the application of; a contract or any clause
thereof which the court finds as a matter of law to have been unconscionable at
the time it was made.

        e. The opinions expressed in this letter are further qualified to the 
extent that the validity, binding nature or enforceability of any provisions of
the Loan Documents may be limited or otherwise affected by:

               i. The unenforceability under certain circumstances under
California or


<PAGE>   138
Bank of America National Trust and Savings Association, 
for itself and as Agent 
June 30, 1997
Page 7


federal law or court decisions of provisions (i) releasing a party against
liability for wrongful or negligent acts, (ii) indemnifying a party to the
extent that the events giving rise to the indemnity arise in whole or in part
from the wrongful or negligent acts of the indemnitee, or (iii) where such
release or indemnification is contrary to public policy, including but not
limited to indemnification and/or releases relating to any issues of securities
laws;

               ii. The effect of California Civil Code Section 1717 and other
applicable statutes and judicial decisions which provide, among other things,
that a court may limit the granting of attorneys' fees to those attorneys' fees
which are determined by the court to be reasonable and that attorneys' fees may
be granted only to a prevailing party and that a contractual provision for
attorneys' fees is deemed to extend to both parties (notwithstanding that such
provision by its express terms benefits only one party);

               iii. The assumption that if the Agent or the Banks enforce their
remedies, they will do so in a commercially reasonable manner;

               iv. The effect of California court decisions invoking statutes or
principles of equity which have held that certain covenants and provisions of
agreements are unenforceable where (i) the breach of such covenants or
provisions imposes restrictions or burdens upon the debtor, including the
acceleration of indebtedness due under debt instruments, and it cannot be
demonstrated that the enforceability of such restrictions or burdens is
reasonably necessary for the protection of the creditors, or (ii) the creditor's
enforcement of such covenants or provisions under the circumstances would
violate the creditor's implied covenants of good faith and fair dealing;

               v. The unenforceability under certain circumstances of
contractual provisions self-help or summary remedies; and

               vi. Decisions by California courts admitting evidence extrinsic
to a written agreement between the parties thereto that the parties intended a
meaning contrary to that expressed by the parties in writing.

        The foregoing opinions are also subject to the following additional
assumptions, limitations, qualifications and exceptions:

        a. Provisions in the Loan Documents requiring Borrower or any Subsidiary
to execute, in the future, additional instruments and documents may be
unenforceable.

        b. Any provision contained in the Loan Documents that purports to
require that any action or decision of Agent or Banks is conclusively binding
upon Borrower or any


<PAGE>   139
Bank of America National Trust and Savings Association, 
for itself and as Agent 
June 30, 1997
Page 8


Subsidiary may be unenforceable.

        c. You are advised that any provision in the Loan Documents purporting
to waive, limit or restrict the right of Borrower or Subsidiary to offset
against obligations owing under the Loan Documents may not be enforceable.

        d. Those provisions in the Loan Documents imposing late charges
(interest or otherwise) and/or additional interest in the event of default are
governed by the rules relating to "liquidated damages" as set forth in
California Civil Code Sections 1671 et seq., and relevant case law (see, e.g.,
Garrett v. Coast and Southern Federal Savings & Loan, 9 Cal.3d 731 (1973)). I
express no opinion as to the effect of judicial decisions and statutes limiting
the enforceability of provisions imposing penalties, forfeitures, late payment
charges, an increase in interest rate, or payment of other additional
consideration, (i) upon prepayment, late payment, maturity, default or a
lender's election to accelerate a loan, particularly in cases where the
occurrence of a default or waiving the benefit of a statutory right bears no
reasonable relation to the damage suffered by the lender or is otherwise held to
be a penalty; or (ii) as a consequence of costs incurred by the lender or
imposition of governmental charges, taxes, levies or requirements upon a lender.

        e. Those provisions in the Loan Documents requiring the consent of Agent
and Banks or allowing Agent or Banks to take certain actions may be interpreted
by a court to contain an implied covenant of reasonableness and/or fair dealing
(see, e.g., Kendall v. Pestana, 40 Cal.3d 488 (1985); Cohen v. Ratinoff, 147
Cal.App.3d 321 (1983)).

        f. You should be aware of the unenforceability, under certain
circumstances, of provisions waiving broadly or vaguely stated rights or unknown
future rights, or rights which may not be waived on statutory or public policy
grounds, or provisions stating that rights or remedies are not exclusive, that
every right or remedy is cumulative and may be exercised in addition to or with
any other right or remedy or that the election of some particular remedy or
remedies does not preclude recourse to one or more others.

        g. You should be aware of limitations based on public policy on
provisions stating that a borrower's obligations are unaffected by reason of any
default or failure on the part of a lender to perform or comply with the terms
of the subject loan documents.

        h. I express no opinion as to the enforceability of the consent to
service, jurisdiction or forum of any claim, demand, action or cause of action
arising under or related to the Loan Documents or the transactions contemplated
therein.

        i. I express no opinion as to the enforceability of any right of any 
creditor to


<PAGE>   140
Bank of America National Trust and Savings Association, 
for itself and as Agent 
June 30, 1997
Page 9


collect any payment due under the Loan Documents to the extent that such payment
constitutes a penalty or forfeiture.

        j. I express no opinion as to the enforceability of provisions in the
Loan Documents creating presumptions or creating rights of set-off.

        k. I express no opinion on the accuracy of any representations or
warranties of Borrower or any Subsidiary. Furthermore I express no opinion as to
the survivability of any warranties, indemnities or other obligations.

        l. I express no opinion as to the enforceability of those provisions in
the Loan Documents purporting to appoint the Agent or Banks as attorney-in-fact
for Borrower or to grant an irrevocable power of attorney to Agent or Banks.

        m. I express no opinion as to the enforceability of provisions in the
Loan Documents purporting to provide that any approval, consent, authorization
or satisfaction required of Agent or Banks or any notice given by or other
action taken by Agent or Banks under the Loan Documents shall be presumed to be
reasonable.

        n. I express no opinion as to the effect of laws and judicial decisions
that provide that in certain circumstances a surety may be exonerated if the
creditor materially alters the original obligation of the principal without the
surety's consent, or otherwise takes any action without notifying the surety
that materially prejudices the surety.

        o. I express no opinion as to any securities, anti-trust, tax, land use,
safety, environmental, hazardous materials, insurance company or banking laws,
rules or regulations, or laws, rules or regulations applicable to Agent or
Banks.

        p. I express no opinion as to any provision providing for the exclusive
jurisdiction of a particular court or purporting to waive rights to trial by
jury, service of process or objections to the laying of venue or to forum on the
basis of forum non conveniens in connection with any litigation arising out of
or pertaining to the Loan Documents.

        q. I express no opinion as to the effect of California Civil Code 
Section 1698 and similar statutes and federal laws and judicial decisions (a)
providing that oral modifications to a contract or waivers of contractual
provisions may be enforceable, if the modification was performed,
notwithstanding any express provision in the agreement that the agreement may 
only be modified or an obligation thereunder waived in writing, or (b) creating
an implied agreement from trade practices or course of conduct.

Page 10


        r. I express no opinion as to the effect of certain rights, remedies and
waivers contained in the Loan Documents being limited or rendered ineffective by
applicable statutory law or judicial decisions governing such provisions, but
such laws and judicial decisions do not render the Loan Documents unenforceable
as a whole, and there exists, in the Loan Documents and pursuant to applicable
law, legally adequate remedies for realization of the principal benefits
purported to be afforded by the Loan Documents.

        s. With respect to my opinions expressed in paragraphs 4(d), 5(d), 7 and
8, I have not conducted any special investigation of statutes laws, rules or
regulations and my opinion with respect thereto are limited to such Laws that to
my knowledge and as in my experience are of general application to transactions
of the sort contemplated by the Loan Documents.

        I further advise you that:

        a. The enforceability of the Guaranty against a Subsidiary may be
subject to California statutory provisions and case law to the effect that a
guarantor may be exonerated if the beneficiary of the guaranty alters the
original obligation of the principal, fair to inform the guarantor of material
information pertinent to the principal or any collateral, elects remedies that
may impair the subrogation rights of the guarantor against the principal or that
may impair the value of the collateral, fails to accord the guarantor the
protections afforded a debtor under the Uniform Commercial Code or otherwise
takes any action that materially prejudices the guarantor unless, in any such
case, the guarantor validly waives such rights or the consequences of any such
action. See, e.g., California Civil Code Section 2799 through Section 2855;
Sumitomo Bank of California v. Iwasaki, 70 Cal. 2d 81, 73 Cal. Rptr. 564 (1968);
Union Bank v. Gradsky, 265 Cal. App. 2d 40, 71 Cal, Rptr 64 (1968); Connolly v.
Bank of Sonoma County., 184 Cal. App. 3d II 19, 229 Cal Rptr. 396 (1986); C.I.T.
Corp. v. Anwright Corp., 191 Cal. App. 3d 1420, 237 Cal. Rptr, 108 (1987);
American National Bank v. Perma-Tile Roof Co., 200 Cal. App. 3d 889, 246 Cal
Rptr. 381 (1988); In re Kirkland, 915 F.2d 1236 (9th Cir. 1990); and Cathay
Bank. v. Lee, 18 Cal. Rptr. 2d 420 (1993). While express and specific waivers of
a guarantor's right to be exonerated, such as those contained hi the Guaranty
are generally enforceable under California law we express no opinion as to
whether the Guaranty contains an express and specific waiver of each exoneration
defense a guarantor might assert or as to whether each of the waivers contained
in the Guaranty is fully enforceable.

        b. It could be contended that the Guaranty has not been given for a fair
or reasonably equivalent consideration, that a Subsidiary is, or, by entering
into the Guaranty may become, insolvent, and that die Guaranty may be voidable
by creditors of a Subsidiary or by a trustee or receiver of a Subsidiary in
bankruptcy or similar proceedings pursuant to

                   FORM OF ASSIGNMENT AND ASSUMPTION AGREEMENT

               This ASSIGNMENT AND ASSUMPTION AGREEMENT (this "Agreement") dated
as of __________ is made between _________________________ (the "Assignor") and
_____________________________ (the "Assignee").

                                    RECITALS

               WHEREAS, the Assignor is party to that certain Restated Credit
Agreement dated as of June 30, 1997 (as amended, amended and restated, modified,
supplemented or renewed, the "Credit Agreement") among Granite Construction
Incorporated, a Delaware corporation (the "Company"), the several financial
institutions from time to time party thereto (including the Assignor, the
"Banks"), and Bank of America National Trust and Savings Association, as letter
of credit issuing bank ("Issuing Bank") and as agent for the Banks (the
"Agent"). Any terms defined in the Credit Agreement and not defined in this
Agreement are used herein as defined in the Credit Agreement;

               WHEREAS, as provided under the Credit Agreement, the Assignor has
committed to make term loans and revolving loans (the "Loans") to the Company
and to issue or participate in standby letters of credit ("Letters of Credit")
issued for the account of the Company or its Subsidiaries in an aggregate amount
not to exceed $_______ (the "Commitment");

               WHEREAS, [the Assignor has made Loans in the aggregate principal
amount of $________ to the Company] [no Loans are outstanding under the Credit
Agreement];

               WHEREAS, [the Assignor has acquired a participation in the
Issuing Bank's liability under Letters of Credit in an aggregate principal
amount of $_________ (the "L/C Obligations")] [no Letters of Credit are
outstanding under the Credit Agreement]; and

               WHEREAS, the Assignor wishes to assign to the Assignee [part of
the] [all] rights and obligations of the Assignor under the Credit Agreement in
respect of its Commitment, [together with a corresponding portion of each of its
outstanding Loans and L/C Obligations,] in an amount equal to $_________ (the
"Assigned Amount") on the terms and subject to the conditions set forth herein
and the Assignee wishes to accept assignment of such rights and to assume such
obligations from the Assignor on such terms and subject to such conditions;

               NOW, THEREFORE, in consideration of the foregoing and the mutual
agreements contained herein, the parties hereto agree as follows:

        1. Assignment and Assumption.

               (a) Subject to the terms and conditions of this Agreement,
(i) the Assignor hereby sells, transfers and assigns to the Assignee, and (ii)
the Assignee hereby purchases,

                                       G-1


<PAGE>   147
assumes and undertakes from the Assignor, without recourse and without
representation or warranty (except as provided in this Agreement) _% (the
"Assignee's Percentage Share") of (A) the Commitment [and the Loans and the L/C
Obligations] of the Assignor and (B) all related rights, benefits, obligations,
liabilities and indemnities of the Assignor under and in connection with the
Credit Agreement and the Loan Documents.

               [If appropriate, add paragraph specifying payment to Assignor by

amount equal to the Assigned Amount. The Assignee agrees that it will perform in
accordance with their terms all of the obligations which by the terms of the
Credit Agreement are required to be performed by it as a Bank. It is the intent
of the parties hereto that the Commitment of the Assignor shall, as of the
Effective Date, be reduced by an amount equal to the Assigned Amount and the
Assignor shall relinquish its rights and be released from its obligations under
the Credit Agreement to the extent such obligations have been assumed by the
Assignee; provided, however, the Assignor shall not relinquish its rights under
Sections 11.4 and 11.5 of the Credit Agreement to the extent such rights relate
to the time prior to the Effective Date.

               (c) After giving effect to the assignment and assumption set
forth herein, on the Effective Date the Assignee's Commitment will be
$__________.

               (b) The [Assignor] [Assignee] further agrees to pay to the Agent
a processing fee in the amount specified in Section 11.07(a) of the Credit
Agreement.

        3. Reallocation of Payments.

        Any interest, fees and other payments accrued to the Effective Date with
respect to the Commitment[,] [and] Loans [and L/C Obligations] shall be for the
account of the Assignor. Any interest, fees and other payments accrued on and
after the Effective Date with respect to the Assigned Amount shall be for the
account of the Assignee. Each of the Assignor and the


                                       G-2


<PAGE>   148
Assignee agrees that it will hold in trust for the other party any interest,
fees and other amounts which it may receive to which the other party is entitled

which it may receive promptly upon receipt.

        4. Independent Credit Decision.

Agreement and the Schedules and Exhibits thereto, together with copies of the

Assignor and the Assignee;

                      (ii) the consent of the Company, the Issuing Bank and the
Agent required for an effective assignment of the Assigned Amount by the
Assignor to the Assignee under Section 11.07(a) of the Credit Agreement shall
have been duly obtained and shall be in full force and effect as of the
Effective Date;

                      (iii) the Assignee shall pay to the Assignor all amounts
due to the Assignor under this Agreement;

                      (iv) the Assignee shall have complied with Section 4.01(f)
of the Credit Agreement (if applicable); and

<PAGE>   149
        6. Agent.

               (a) The Assignee hereby appoints and authorizes the Agent to take
such action as agent on its behalf and to exercise such powers under the Credit
Agreement as are delegated to the Agent by the Banks pursuant to the terms of
the Credit Agreement.

               [(b) [INCLUDE ONLY IF ASSIGNOR IS AGENT] The Assignee shall
assume no duties or obligations held by the Assignor in its capacity as Agent
under the Credit Agreement.]

        7. Withholding Tax.

        The Assignee (a) represents and warrants to the Agent and the Company
that under applicable law and treaties no tax will be required to be withheld by
the Agent with respect to any payments to be made to the Assignee hereunder, (b)
agrees to furnish (if it is organized under the laws of any jurisdiction other

                                FORM OF GUARANTY

               This Guaranty is entered into as of June 30, 1997, jointly and
severally by each of the parties set forth under the caption "GUARANTORS" on the
signature pages hereto (each, a "Guarantor"), in favor of each Lender Party (as
defined below).

                                    Recitals

               A. Pursuant to a Credit Agreement, dated as of June 30, 1997
(together with all amendments and other modifications, supplements, restatements
and extensions, if any, from time to time thereafter made thereto, the "Credit
Agreement"), among Granite Construction Incorporated, a Delaware corporation
(the "Company"), the various financial institutions (individually, a "Bank" and
collectively, the "Banks") as are, or may from time to time become, parties
thereto, and Bank of America National Trust and Savings Association, as the
agent for such Banks (together with any successors) thereto in such capacities,
the "Agent"), the Banks have provided the Commitments and agreed to make Loans
to the Company and to participate in Letters of Credit issued by the Issuing
Bank for the account of the Company or its Subsidiaries.

               B. One of the conditions precedent to the effectiveness of the
Credit Agreement is the execution and delivery of this Guaranty by each
Guarantor.

               C. Each Guarantor has duly authorized the execution, delivery and
performance by it of this Guaranty.

               D. It is in the best interests of each Guarantor to execute this
Guaranty inasmuch as such Guarantor will derive substantial direct and indirect
benefits from the Loans made and the Letters of Credit issued from time to time
pursuant to the Credit Agreement.

               NOW THEREFORE, for good and valuable consideration, the receipt
and sufficiency of which is hereby acknowledged, and in order to induce (i) the
Banks to make Loans (including the initial Loans) to the Company, (ii) the
Issuing Bank to issue and the Banks to participate in Letters of Credit issued
by the Issuing Bank for the account of the Company or its Subsidiaries, all
pursuant to the Credit Agreement, each Guarantor jointly and several agrees, for
the benefit of each Lender Party, as follows:

1.      Definitions.  Unless otherwise defined herein, capitalized terms used in
this Guaranty have the meanings given to them in the Credit Agreement, and as
used herein, "Lender Party" means, as the context may require, any Bank, the
Issuing Bank or the Agent and each of its successors, transferees and assigns.


                                       H-1


<PAGE>   157
2.      Guaranty.

        2.1 Guaranty. Each Guarantor hereby jointly and severally
unconditionally guarantees and promises to pay to the Lender Parties or order,
on demand, any and all Obligations of the Company to the Lender Parties from
time to time outstanding under or in respect to the Credit Agreement or any
other Loan Document (the "Obligations"); provided, however, that each Guarantor
shall be jointly and severally liable under this Guaranty for the maximum amount
of such liability that can be hereby incurred by such Guarantor without
rendering this Guaranty, as it relates to such Guarantor, void or voidable under
applicable law relating to fraudulent conveyance, fraudulent transfer or similar
law (including the California Uniform Fraudulent Transfer Act and Sections 544
and 548 of the Federal Bankruptcy Reform Act of 1978, as amended (11 U.S.C.
Section 101, et seq.) (the "Bankruptcy Code")) and not for any greater amount,
and the Lender Parties by their acceptance hereof accept such limitation to the
extent needed to make this Guaranty fully enforceable and nonavoidable. Any
Lender Party may permit the indebtedness of the Company to such Lender Party to
include indebtedness other than the Obligations, and may apply any amounts
received from any source, other than from any Guarantor, to that portion of
Company's indebtedness to such Lender Party which is not a part of the
0bligations.

        2.2 Obligations Independent. The obligations hereunder are joint and
several, and independent of the obligations of the Company, and a separate
action or actions may be brought and prosecuted against any Guarantor whether
action is brought against the Company or any other Guarantor or guarantor or
whether the Company or any other Guarantor or guarantor be joined in any such
action or actions. Each Guarantor waives the benefit of any statute of
limitations affecting its liability hereunder. Each Guarantor acknowledges that
in providing benefits to the Company, the Lender Parties are relying upon the
enforceability of this Guaranty and the Obligations as separate and distinct
indebtedness, obligations and liabilities of each Guarantor.

        2.3 Authorization of Renewals, Etc. Each Guarantor authorizes each
Lender Party, without notice or demand and without affecting its liability
hereunder, from time to time to:

               (a) renew, compromise, extend, accelerate or otherwise change the
time for payment, or otherwise change the terms, of the Obligations, including
increase or decrease of the rate of interest thereon, or otherwise change the
terms of the Credit Agreement or any other Loan Document;

               (b) receive and hold security for the payment of this Guaranty or
the Obligations and exchange, enforce, waive, release, fail to perfect, sell, or
otherwise dispose of any such security;

               (c) apply such security and direct the order or manner of sale
thereof as any Lender Party in its or their discretion may determine; and

               (d) release or substitute any one or more of any endorsers or
guarantors of the Obligations.


                                       H-2


<PAGE>   158
Further, the performance or occurrence of any of the acts or events described in
clauses (a), (b), (c), and (d) above with respect to indebtedness of the
Company, other than the Obligations, to any Lender Party shall not affect the
liability of any Guarantor hereunder.

        2.4 Waiver of Certain Rights. Each Guarantor waives any right to require
any Lender Party to:

               (a) proceed against the Company or any other Guarantor or
guarantor;

               (b) proceed against or exhaust any security or other guaranty for
the Obligations or any other indebtedness of the Company to any Lender Party; or

               (c) pursue any other remedy in the Lender Parties' power
whatsoever.

        2.5 Waiver of Certain Defenses. Each Guarantor waives any defense
arising by reason of any disability, lack of corporate authority or other
defense of the Company, or the cessation from any cause whatsoever of the
liability of the Company, or any claim that such Guarantor's obligations exceed
or are more burdensome than those of the Company. Each Guarantor waives all
rights and defenses arising out of an election of remedies by the Lender
Parties, even though that election of remedies, such as a nonjudicial
foreclosure with respect to security for the Obligations, has destroyed the
Guarantor's rights of subrogation and reimbursement against the Company by
operation of Section 580d of the California Code of Civil Procedure or
otherwise, and all rights or defenses the Guarantor may have by reason of
protection afforded to the Company with respect to the Obligations pursuant to
the antideficiency laws or other laws of the state of California limiting or
discharging the Obligations. Each Guarantor waives any benefit of, and any right
to participate in, any security or other guaranty now or hereafter held by the
Lender Parties securing the Obligations. Each Guarantor waives, to the fullest
extent permitted by law, any defenses or benefits that may be derived from or
afforded by applicable law limiting the liability of or exonerating guarantors
or sureties, or which may conflict with the terms of this Guaranty, including
any and all benefits that otherwise might be available to any Guarantor under
California Civil Code Sections 1432, 2810, 2815, 2819, 2845, 2848, 2849, 2850,
2899 and 3433 and California Code of Civil Procedure Sections 580a, 580b, 580d
and 726.

        2.6 Subrogation, etc. At any time that a payment is made by any
Guarantor with respect to the Obligations, such Guarantor shall have a right of
contribution against the Company and each other Person (other than any Lender
Party) obligated under, or otherwise a party to, any Loan Document (each, an
"Obligor") and each other Obligor shall have an obligation to indemnify such
Guarantor in me maximum amount permitted by applicable law, which right of
contribution and indemnity shall be subject to adjustment at the time of any
subsequent payment with respect to the Obligations; provided, however, that the
maximum aggregate liability of any Guarantor shall not exceed the maximum amount
of liability that such Guarantor can incur without rendering such contribution
and indemnity rights void or voidable under applicable law relating to
fraudulent conveyance or fraudulent transfers or similar law, and not for any
greater amount; provided, further, however, that no Guarantor will exercise any
rights which it may acquire by reason of any payment made hereunder, whether by
way of rights of subrogation,


                                       H-3


<PAGE>   159
reimbursement or otherwise, until the prior payment, in full and in cash, of all
Obligations of the Company and each other Obligor and the termination of the
Commitments and the expiry of the Letters of Credit. Any amount paid to any
Guarantor on account of any payment made hereunder prior to the payment in full
of all Obligations of the Company and each other Obligor shall be held in trust
for the benefit of the Lender Parties and shall immediately be paid to the Agent
and credited and applied against the Obligations of the Company and each other
Obligor, whether matured or unmatured, in accordance with the terms of the
Credit Agreement; provided, however, that if

               (a) any Guarantor has made payment to the Lender Parties of all
or any part of the Obligations of the Company or any other Obligor, and

               (b) all Obligations of the Company and each other Obligor have
been paid in full and all Commitments and Letters of Credit have expired or been
permanently terminated, at such Guarantor's request, the Agent, on behalf of the
Lender Parties, will execute and deliver to such Guarantor appropriate documents
(without recourse and without representation or warranty) necessary to evidence
the transfer by subrogation to such Guarantor of an interest in the Obligations
of the Company and each other Obligor resulting from such payment by such
Guarantor. In furtherance of the foregoing, for so long as any Obligations,
Letters of Credit or Commitments remain outstanding, each Guarantor shall
refrain from taking any action or commencing any proceeding against the Company
or any other Obligor (or its successors or assigns, whether in connection with a
bankruptcy proceeding or otherwise) to recover any amounts in respect of
payments made under this Guaranty to any Lender Party.

        2.7 Waiver of Presentments, Etc. Each Guarantor waives all presentments,
demands for performance, notices of nonperformance, protests, notices of
protest, notices of dishonor, and notices of acceptance of this Guaranty and of
the existence, creation, extension or incurring of the Obligations or any new or
additional Obligations or any other indebtedness of Company to any of the Lender
Parties, or the reliance by any Lender Party upon this Guaranty, or the exercise
of any right, power or privilege hereunder.

        2.8 Information Relating to Company. Each Guarantor acknowledges and
agrees that it shall have the sole responsibility for obtaining from the Company
such information concerning the Company's financial condition or business
operations as such Guarantor may require, and that no Lender Party has any duty
at any time to disclose to any Guarantor any information relating to the
business operations or financial condition of the Company.

        2.9 Right of Setoff. In addition to any rights and remedies of the
Lender Parties provided by law, if an Event of Default exists, each Lender Party
is authorized at any time and from time to time, without prior notice to any
Guarantor, any such notice being waived by each Guarantor to the fullest extent
permitted by law, to set-off and apply any and all deposits (general or special,
time or demand, provisional or final) at any time held and other indebtedness at
any time owing by such Lender Party to or for the credit or the account of any
Guarantor against any and all obligations of such Guarantor now or hereafter
existing under this Guaranty or any other Loan


                                       H-4

Document, irrespective of whether or not the Lender Party shall have made demand
under this Guaranty or any other Loan Document and although such obligations may
be contingent or unmatured. Each Lender Party agrees promptly to notify the
applicable Guarantor and the Agent after any such set-off and application made
by such Lender Party; provided, however, that the failure to give such notice
shall not affect the validity of such set-off and application. The rights of
each Lender Party under this Section 2.9 are in addition to the other rights and
remedies (including without limitation, other rights of set-off) which such
Lender Party may have.

        2.10 Subordination. Any obligations of the Company to any Guarantor, now
or hereafter existing, including but not limited to any obligations to any
Guarantor as subrogee of any Lender Party or resulting from any Guarantor's
performance under this Guaranty, are hereby subordinated to the Obligations and
all other indebtedness (including any interest that would accrue pursuant to the
terms of the Loan Documents or other agreements after commencement of any
Insolvency Proceeding, whether or not allowed as a claim) of the Company to the
Lender Parties. Such obligations of the Company to any Guarantor if the Majority
Banks so request shall be enforced and performance received by such Guarantor as
trustee for the Lender Parties and the proceeds thereof shall be paid over to
the Lender Parties on account of the Obligations, but without reducing or
affecting in any manner the liability of any Guarantor under the other
provisions of this Guaranty. The Lender Parties shall be entitled to enforce all
of such Guarantor's rights with respect to such obligations of the Company to
such Guarantor, including in any Insolvency Proceeding. Any amounts received by
any Guarantor in contravention of this Section 2.10 shall be held in trust for
the benefit of the Lender Parties and shall be paid over or delivered to the
Agent for application to the payment of all Obligations or held as cash
collateral to the extent necessary to give effect to this Guaranty.

        2.11 Reinstatement of Guaranty. If this Guaranty is returned or
canceled, and subsequently any payment or transfer of any interest in property
by the Company to the any Lender Party in fulfillment of any Obligation is
rescinded or must be returned by the Lender Party to the Company, this Guaranty
shall be reinstated with respect to any such payment or transfer, regardless of
any such prior return or cancellation.

        2.12 Powers. It is not necessary for the any Lender Party to inquire
into the powers of the Company or of the officers, directors, partners or agents
acting or purporting to act on its behalf, and any Obligations made or created
in reliance upon the professed exercise of such powers shall be guaranteed
hereunder.

2.13    Taxes.

               (a) Subject to subsection 2.13(g), any and all payments by any
Guarantor to each Lender Party under this Guaranty or any other Loan Documents
shall be made free and clear of, and without deduction or withholding for, any
and all present or future taxes, levies, imposts, deductions, charges or
withholdings, and all liabilities with respect thereto, excluding, in the case
of each Lender Party, such taxes (including income taxes or franchise taxes) as
are imposed on or measured by each Lender Party's net income by the jurisdiction
under the laws of which such Lender Party is organized or maintains a Lending
Office or any political subdivision thereof (all



                                       H-5



<PAGE>   161
such non-excluded taxes, levies, imposts, deductions, charges, withholdings and
liabilities being hereinafter referred to as "Taxes").

               (b) In addition, each Guarantor shall pay any present or future
stamp or documentary taxes or any other excise or property taxes, charges or
similar levies which arise from any payment made hereunder or from the
execution, delivery or registration of, or otherwise with respect to, this
Guaranty or any other Loan Documents (hereinafter referred to as "Other Taxes").

               (c) Subject to subsection 2.13(g), each Guarantor shall indemnify
and hold harmless each Lender Party for the full amount of Taxes or Other Taxes
(including without limitation, any Taxes or Other Taxes imposed by any
jurisdiction on amounts payable under this Section 2.13) paid by the Lender
Party and any liability (including penalties, interest, additions to tax and
expenses) arising therefrom or with respect thereto, in the amount necessary to
preserve the after-tax yield such Lender Party would have received if such Taxes
or Other Taxes had not been imposed, whether or not such Taxes or Other Taxes
were correctly or legally asserted. Payment under this indemnification shall be
made within 30 days from the date the Lender Party makes written demand
therefor. Should such Lender Party determine in its sole discretion to seek a
refund or rebate of some or all of the amount of Taxes, Other Taxes or other
liability paid by it and for which it was indemnified by a Guarantor and should
it receive some or all of the refund or rebate which it sought, it shall return
to such Guarantor the difference between the amount of such refund or rebate and
its reasonable costs and expenses of counsel (and the allocated cost of internal
counsel) incurred by it in procuring such refund or rebate.

               (d) If any Guarantor shall be required by law to deduct or
withhold any Taxes or Other Taxes from or in respect of any sum payable
hereunder to any Lender Party, then, subject to subsection 2.13(g):

                             (i) the sum payable shall be increased as 
        necessary so that after making all required deductions (including
        deductions applicable to additional sums payable under this Section
        2.13) such Lender Party receives an amount equal to the sum it would
        have received had no such deductions been made;

                             (ii) such Guarantor shall make such deductions; and

                             (iii) such Guarantor shall pay the full amount
        deducted to the relevant taxation authority or other authority in
        accordance with applicable law.

               (e) Within 30 days after the date of any payment by any Guarantor
of Taxes or Other Taxes, such Guarantor shall furnish to the affected Lender
Party the original or a certified copy of a receipt evidencing payment thereof
or other evidence of payment satisfactory to such Lender Party

               (f) Each Lender Party which is a foreign person (i.e., a person
other than a United States person for United States Federal income tax purposes)
agrees that:



                                       H-6


<PAGE>   162
                      (i) it shall, no later than the Closing Date (or, in the
case of a Bank which becomes a Lender Party pursuant to Section 4.1 after the
Closing Date, the date upon which such Bank becomes a Lender Party) deliver to
the Guarantor through the Agent:

               (A) if any Lending Office is located in the United States, two
        accurate and complete signed originals of Internal Revenue Service Form
        4224 or any successor thereto ("Form 4224"), and

               (B) if any Lending Office is located outside the United States,
        two accurate and complete signed originals of Internal Revenue Service
        Form 1001 or any successor thereto ("Form 1001"), in each case
        indicating that such Bank is on the date of delivery thereof entitled to
        receive payments of principal, interest and fees for the account of such
        Lending Office or Offices under this Guaranty free from withholding of
        United States Federal income tax;

                      (ii) if at any time any Bank changes its Lending Office or
Offices or selects an additional Lending Office as herein provided, it shall
with reasonable promptness deliver to the Guarantor through the Agent in
replacement for, or in addition to, the forms previously delivered by it
hereunder:

               (A) if such changed or additional Lending Office is located in
        the United States, two accurate and complete signed originals of Form
        4224; or

               (B) otherwise, two accurate and complete signed originals of 
        Form 1001, in each case indicating that such Bank is on the date of
        delivery thereof entitled to receive payments of principal, interest and
        fees for the account of such changed or additional Lending Office under
        this Guaranty free from withholding of United States federal income tax;

                      (iii) it shall, before or promptly after the occurrence of
any event (including the passing of time but excluding any event mentioned in
(ii) above) requiring a change in the most recent Form 4224 or Form 1001
previously delivered by such Bank and if the delivery of the same be lawful,
deliver to the Guarantor through the Agent two accurate and complete original
signed copies of Form 4224 or Form 1001 in replacement for the forms previously
delivered by the Bank; and

                      (iv) it shall, promptly upon any Guarantor's reasonable
request to that effect, deliver to such Guarantor such other forms or similar
documentation as may be required from time to time by any applicable law,
treaty, rule or regulation in order to establish such Bank's tax status for
withholding purposes.

<PAGE>   163
               (g) No Guarantor will be required to pay any additional amounts
in respect of United States federal income tax pursuant to subsection 2.13(d) to
any Bank for the account of any Lending Office of such Bank:

                      (i) if the obligation to pay such additional amounts would
        not have arisen but for a failure by such Bank to comply with its
        obligations under subsection 2.13(f) in respect of such Lending Office;

                      (ii) if such Bank shall have delivered to such Guarantor a
        Form 4224 in respect of such Lending Office pursuant to subsection
        2.13(f)(i)(A), and such Bank shall not at any time be entitled to
        exemption from deduction or withholding of United States federal income
        tax in respect of payments by such Guarantor hereunder for the account
        of such Lending Office for any reason other than a change in United
        States law or regulations or in the official interpretation of such law
        or regulations by any governmental authority charged with the
        interpretation or administration thereof (whether or not having the
        force of law) after the date of delivery of such Form 4224; or

                      (iii) if the Bank shall have delivered to such Guarantor a
        Form 1001 in respect of such Lending Office pursuant to subsection
        2.13(f)(i)(B), and such Bank shall not at any time be entitled to
        exemption from deduction or withholding of United States Federal income
        tax in respect of payments by such Guarantor hereunder for the account
        of such Lending Office for any reason other than a change in United
        States law or regulations or any applicable tax treaty or regulations or
        in the official interpretation of any such law, treaty or regulations by
        any governmental authority charged with the interpretation or
        administration thereof (whether or not having the force of law) after
        the date of delivery of such Form 1001.

               (h) If any Guarantor is required to pay additional amounts to any
Lender Party pursuant to subsection 2.13(d), then such Lender Party shall use
its reasonable best efforts (consistent with legal and regulatory restrictions)
to change the jurisdiction of its Lending Office so as to eliminate any such
additional payment by such Guarantor which may thereafter accrue if such change
in the judgment of such Lender Party is not otherwise significantly
disadvantageous to such Lender Party.

               (i) The agreements and obligations of each Guarantor contained in
this Section 2.13 shall survive the payment in full of all other Obligations.

        2.14 Continuing Guaranty. This Guaranty is a continuing guaranty and
agreement of subordination and shall continue in effect and be binding upon each
Guarantor until termination of the Commitments, existing of the Letters of
Credit and payment and performance in full of the Obligations which may exist or
which may arise from time to time under successive transactions, and each
Guarantor expressly acknowledges that this Guaranty shall remain in full force
and effect notwithstanding that there may be periods in which no Obligations
exist. This Guaranty supersedes all prior guaranties executed from time to time
by any of the Guarantors in connection with the Second Amended and Restated
Credit Agreement dated as of June 15, 1995, as amended


                                       H-8


<PAGE>   164
from time to time, among the Company, the financial institutions party thereto
as "Banks" and Bank of America NT & SA as the Agent for the Banks.

        2.15 Substantial Benefits. The funds that have been borrowed from the
Banks by the Company and the Issuance of any Letter of Credit by the Issuing
Bank have been and are to be contemporaneously used for the benefit of the
Company and the Guarantors. The Company and the Guarantors have derived and will
derive significant and substantial benefits from the accommodations that have
been made by the Banks and the Issuing Bank under the Loan Documents. The
Guarantors have received at least "reasonably equivalent value" (as such phrase
is used in Section 548 of the Bankruptcy Code, in Section 3439.04 of the
California Uniform Fraudulent Transfer Act and in comparable provisions of other
applicable law) and more than sufficient consideration to support its
obligations hereunder in respect of the Obligations and under any of the Loan
Documents to which it is a party.

3. Representations and Warranties. Each Guarantor represents and warrants to the
Lender Parties that (a) such Guarantor and the Company are distinct and separate
entities operating independently; (b) such Guarantor has received copies of the
Credit Agreement and the other Loan Documents and is familiar with and fully
understands of all their respective terms and conditions; (c) no Lender Party
has made any representations or warranties to such Guarantor regarding the
creditworthiness of the Company or the prospects of repayment from sources other
than the Company; (d) this Guaranty is executed at the request of the Company;
(e) such Guarantor has established adequate means of obtaining from the Company
on a continuing basis financial and other information pertaining to the business
of the Company; and (f) such Guarantor is Solvent (both before and after giving
effect to this Guaranty, taking into account such Guarantor's rights of
contribution and indemnity as provided in Section 2.6).

2. Miscellaneous

        4.1 Participations; Novations. Any Lender Party may from time to time,
without notice to any Guarantor and without affecting any Guarantor's
obligations hereunder, transfer its interest in the Obligations to Participants
and Assignees (each as defined in the Credit Agreement) as provided in the
Credit Agreement. Each Guarantor agrees that each such transfer will give rise
to a direct obligation of such Guarantor to each such Participant and Assignee
and that each such Participant and Assignee shall have the same rights and
benefits under this Guaranty as it would have if it were a Bank party to the
Credit Agreement and this Guaranty. Each Lender Party agrees to maintain the
confidentiality of all non-public information provided to it by any Guarantor or
by the Agent on such Guarantor's behalf to the same extent and with the same
exceptions as provided in the Credit Agreement. Notwithstanding the foregoing,
each Guarantor authorizes the Agent and each other Lender Party to disclose to
any prospective Participant and Assignee and any Participant and Assignee any
and all confidential information in the Agent's and such Lender Party's
possession concerning the Guarantor, this Guaranty and any security for this
Guaranty; provided, however, that such Participant or Assignee or such
prospective Participant or Assignee agrees in writing to the Agent or such
Lender Party, as the case may be, to keep such information confidential to the
same extent required by the Lender Parties under the Credit Agreement.

<PAGE>   165
        4.2 Merger. In the event that (i) one or more Guarantors is merged into
the Company or another Guarantor or (ii) one or more of the Guarantors is sold
or liquidated, subject, in each case, to the provisions of the Credit Agreement,
such Guarantor shall cease to be a Guarantor hereunder without the necessity to
amend or re-issue this Guaranty, and each Guarantor agrees that its obligations
hereunder shall continue in full force and effect hereunder and shall not be
affected by any such merger, sale or liquidation.

        4.3 Waivers; Writing Required. No delay or omission by any Lender Party
to exercise any right under this Guaranty shall impair any such right, nor shall
it be construed to be a waiver thereof. No waiver of any single breach or 
default under this Guaranty shall be deemed a waiver of any other breach or
default. Any amendment or waiver of any provision of this Guaranty must be in
writing to be effective.

        4.4 Remedies. All rights and remedies provided in this Guaranty and any
instrument or agreement referred to herein are cumulative and are not exclusive
of any rights or remedies otherwise provided by law. Any single or partial
exercise of any right or remedy shall not preclude the further exercise thereof
or the exercise of any other right or remedy..

        4.5 Costs and Expenses. Each Guarantor agrees to pay to each Lender
Party on demand all costs, expenses and attorneys' fees (including allocated
costs for in-house legal services) incurred by each such Lender Party in
connection with the enforcement of this Guaranty.

        4.6 Section Headings. Interpretation. Section headings are for reference
only, and shall not affect the interpretation or meaning of any provision of
this Guaranty. Unless otherwise provided, references to Articles, Sections and
Exhibits shall be deemed references to Articles, Sections and Exhibits of this
Guaranty. All references to the word "Guarantor" or "the Guarantors" shall mean
all and any one or more of them, as the context shall require.

        4.7 Severability. The illegality or unenforceability of any provision of
this Guaranty or any instrument or agreement referred to herein shall not in any
way affect or impair the legality or enforceability of the remaining provisions
of this Guaranty or any instrument or agreement referred to herein.

        4.8 Governing, Law and Jurisdiction.

               (a) THIS GUARANTY SHALL BE GOVERNED BY, AND CONSTRUED IN
ACCORDANCE WITH, THE LAW OF THE STATE OF CALIFORNIA.

               (b) ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THIS GUARANTY
AND ANY OTHER LOAN DOCUMENTS MAY BE BROUGHT IN THE COURTS OF THE STATE OF
CALIFORNIA OR OF THE UNITED STATES FOR THE NORTHERN DISTRICT OF CALIFORNIA, AND
BY EXECUTION AND DELIVERY OF THIS GUARANTY, EACH GUARANTOR AND EACH LENDER PARTY
CONSENTS, FOR ITSELF AND IN RESPECT OF ITS PROPERTY, TO THE JURISDICTION OF
THOSE COURTS. EACH GUARANTOR AND EACH LENDER PARTY IRREVOCABLY WAIVES



                                      H-10



<PAGE>   166
ANY OBJECTION, INCLUDING ANY OBJECTION TO THE LAYING OF VENUE OR BASED ON THE
GROUNDS OF FORUM NON CONVENIENS, WHICH IT MAY NOW OR HEREAFTER HAVE TO THE
BRINGING OF ANY ACTION OR PROCEEDING IN SUCH JURISDICTION IN RESPECT OF THIS
GUARANTY OR ANY DOCUMENT RELATED HERETO. EACH GUARANTOR AND EACH LENDER PARTY
EACH WAIVE PERSONAL SERVICE OF ANY SUMMONS, COMPLAINT OR OTHER PROCESS, WHICH
MAY BE MADE BY ANY OTHER MEANS PERMITTED BY CALIFORNIA LAW.

        4.9 Separate Obligations. This Guaranty creates separate obligations of
each Guarantor in favor of the Lender Parties. The fact that such obligations
are set forth in this one Guaranty rather than in a separate guaranty document
for each Guarantor is for the convenience of the Company and the Guarantors and
shall in no way impair or adversely affect the rights or benefits of any of the
Lender Parties hereunder. Each Guarantor agrees to execute and deliver a
separate agreement, immediately upon request at any time of the Majority Banks,
evidencing such Guarantor's obligations under this Guaranty.

        4.10 Entire Agreement. This Guaranty and any instrument, agreement or
document attached hereto or referred to herein (a) integrate all the terms and
conditions mentioned herein or incidental hereto, (b) supersede all oral
negotiations and prior writings with respect to the subject matter hereof, and
(c) are intended by the parties as the final expression of the agreement with
respect to the terms and conditions set forth in this Guaranty and any such
instrument, agreement and document and as the complete and exclusive statement
of the terms agreed to by the parties. In the event of any conflict between the
terms, conditions and provisions of this Guaranty and any such instrument,
agreement or document, the terms, conditions and provisions of this Guaranty
shall prevail.

                                    GUARANTY


            This Guaranty is entered into as of June 30, 1997, jointly and
severally by each of the parties set forth under the caption "GUARANTORS" on the
signature pages hereto (each, a "Guarantor"), in favor of each Lender Party (as
defined below).

                                    Recitals

            A. Pursuant to a Credit Agreement, dated as of June 30, 1997
(together with all amendments and other modifications, supplements, restatements
and extensions, if any, from time to time thereafter made thereto, the "Credit
Agreement"), among Granite Construction Incorporated, a Delaware corporation
(the "Company"), the various financial institutions (individually, a "Bank" and
collectively, the "Banks") as are, or may from time to time become, parties
thereto, and Bank of America National Trust and Savings Association, as the
agent for such Banks (together with any successor(s) thereto in such capacities,
the "Agent"), the Banks have provided the Commitments and agreed to make Loans
to the Company and to participate in Letters of Credit issued by the Issuing
Bank for the account of the Company or its Subsidiaries.

            B. One of the conditions precedent to the effectiveness of the
Credit Agreement is the execution and delivery of this Guaranty by each
Guarantor.

            C. Each Guarantor has duly authorized the execution, delivery and
performance by it of this Guaranty.

            D. It is in the best interests of each Guarantor to execute this
Guaranty inasmuch as such Guarantor will derive substantial direct and indirect
benefits from the Loans made and the Letters of Credit issued from time to time
pursuant to the Credit Agreement.

            NOW THEREFORE, for good and valuable consideration, the receipt and
sufficiency of which is hereby acknowledged, and in order to induce (i) the
Banks to make Loans (including the initial Loans) to the Company, (ii) the
Issuing Bank to issue and the Banks to participate in Letters of Credit issued
by the Issuing Bank for the account of the Company or its Subsidiaries, all
pursuant to the Credit Agreement, each Guarantor jointly and several agrees, for
the benefit of each Lender Party, as follows:

1. Definitions. Unless otherwise defined herein, capitalized terms used in this
Guaranty have the meanings given to them in the Credit Agreement, and as used
herein, "Lender Party" means, as the context may require, any Bank, the Issuing
Bank or the Agent and each of its successors, transferees and assigns.

2.    Guaranty.

      2.1 Guaranty. Each Guarantor hereby jointly and severally unconditionally
guarantees and promises to pay to the Lender Parties or order, on demand, any
and all Obligations of the Company to the Lender Parties from time to time
outstanding under or in respect to the Credit Agreement or any other Loan
Document (the "Obligations"); provided, however, that each Guarantor shall be
jointly and severally liable under this Guaranty for the maximum amount of such
liability that can be hereby incurred by such Guarantor without rendering this
Guaranty, as it relates to such Guarantor, void or voidable under applicable law
relating to fraudulent conveyance, fraudulent transfer or similar law (including
the California Uniform Fraudulent Transfer Act and Sections 544 and 548 of the
Federal Bankruptcy Reform Act of 1978, as amended (11 U.S.C. Section 101, et
seq.). (the "Bankruptcy Code")), and not for any greater amount, and the Lender
Parties by their acceptance hereof accept such limitation to the extent needed
to make this Guaranty fully enforceable and nonavoidable. Any Lender Party may
permit the indebtedness of the Company to such Lender Party to include
indebtedness other than the Obligations, and may apply any amounts received from
any source, other than from any Guarantor, to that portion of Company's
indebtedness to such Lender Party which is not a part of the Obligations.

      2.2 Obligations Independent. The obligations hereunder are joint and
several, and independent of the obligations of the Company, and a separate
action or actions may be brought and prosecuted against any Guarantor whether
action is brought against the Company or any other Guarantor or guarantor or
whether the Company or any other Guarantor or guarantor be joined in any such
action or actions. Each Guarantor waives the benefit of any statute of
limitations affecting its liability hereunder. Each Guarantor acknowledges that
in providing benefits to the Company, the Lender Parties are relying upon the
enforceability of this Guaranty and the Obligations as separate and distinct
indebtedness, obligations and liabilities of each Guarantor.

      2.3 Authorization of Renewals, Etc. Each Guarantor authorizes each Lender
Party, without notice or demand and without affecting its liability hereunder,
from time to time to:

            (a) renew, compromise, extend, accelerate or otherwise change the
time for payment, or otherwise change the terms, of the Obligations, including
increase or decrease of the rate of interest thereon, or otherwise change the
terms of the Credit Agreement or any other Loan Document;

            (b) receive and hold security for the payment of this Guaranty or
the Obligations and exchange, enforce, waive, release, fail to perfect, sell, or
otherwise dispose of any such security;

            (c) apply such security and direct the order or manner of sale
thereof as any Lender Party in its or their discretion may determine; and


                                        2


<PAGE>   182
            (d) release or substitute any one or more of any endorsers or
guarantors of the Obligations.

Further, the performance or occurrence of any of the acts or events described in
clauses (a), (b), (c), and (d) above with respect to indebtedness of the
Company, other than the Obligations, to any Lender Party shall not affect the
liability of any Guarantor hereunder.

      2.4 Waiver of Certain Rights. Each Guarantor waives any right to require
any Lender Party to:

            (a) proceed against the Company or any other Guarantor or guarantor;

            (b) proceed against or exhaust any security or other guaranty for
the Obligations or any other indebtedness of the Company to any Lender Party; or

            (c) pursue any other remedy in the Lender Parties' power whatsoever.

      2.5 Waiver of Certain Defenses. Each Guarantor waives any defense arising
by reason of any disability, lack of corporate authority or other defense of the
Company, or the cessation from any cause whatsoever of the liability of the
Company, or any claim that such Guarantor's obligations exceed or are more
burdensome than those of the Company. Each Guarantor waives all rights and
defenses arising out of an election of remedies by the Lender Parties, even
though that election of remedies, such as a nonjudicial foreclosure with respect
to security for the Obligations, has destroyed the Guarantor's rights of
subrogation and reimbursement against the Company by operation of Section 580d
of the California Code of Civil Procedure or otherwise, and all rights or
defenses the Guarantor may have by reason of protection afforded to the Company
with respect to the Obligations pursuant to the antideficiency laws or other
laws of the state of California limiting or discharging the Obligations. Each
Guarantor waives any benefit of, and any right to participate in, any security
or other guaranty now or hereafter held by the Lender Parties securing the
Obligations. Each Guarantor waives, to the fullest extent permitted by law, any
defenses or benefits that may be derived from or afforded by applicable law
limiting the liability of or exonerating guarantors or sureties, or which may
conflict with the terms of this Guaranty, including any and all benefits that
otherwise might be available to any Guarantor under California Civil Code
Sections 1432, 2810, 2815, 2819, 2845, 2848, 2849, 2850, 2899 and 3433 and
California Code of Civil Procedure Sections 580a, 580b, 580d and 726.

      2.6 Subrogation, etc.. At any time that a payment is made by any Guarantor
with respect to the Obligations, such Guarantor shall have a right of
contribution against the Company and each other Person (other than any Lender
Party) obligated under, or otherwise a party to, any Loan Document (each, an
"Obligor") and each other Obligor shall have an obligation to indemnify such
Guarantor in the maximum amount permitted by applicable law, which right of
contribution and indemnity shall be subject to adjustment at the time of any
subsequent payment with respect to the Obligations; provided, however, that the
maximum aggregate liability of any Guarantor shall not exceed the maximum amount
of liability that such Guarantor can incur


                                        3


<PAGE>   183
without rendering such contribution and indemnity rights void or voidable under
applicable law relating to fraudulent conveyance or fraudulent transfers or
similar law, and not for any greater amount; provided, further, however, that no
Guarantor will exercise any rights which it may acquire by reason of any payment
made hereunder, whether by way of rights of subrogation, reimbursement or
otherwise, until the prior payment, in full and in cash, of all Obligations of
the Company and each other Obligor and the termination of the Commitments and
the expiry of the Letters of Credit. Any amount paid to any Guarantor on account
of any payment made hereunder prior to the payment in full of all Obligations of
the Company and each other Obligor shall be held in trust for the benefit of the
Lender Parties and shall immediately be paid to the Agent and credited and
applied against the Obligations of the Company and each other Obligor, whether
matured or unmatured, in accordance with the terms of the Credit Agreement;
provided, however, that if

            (a) any Guarantor has made payment to the Lender Parties of all or
any part of the Obligations of the Company or any other Obligor, and

            (b) all Obligations of the Company and each other Obligor have been
paid in full and all Commitments and Letters of Credit have expired or been
permanently terminated,

at such Guarantor's request, the Agent, on behalf of the Lender Parties, will
execute and deliver to such Guarantor appropriate documents (without recourse
and without representation or warranty) necessary to evidence the transfer by
subrogation to such Guarantor of an interest in the Obligations of the Company
and each other Obligor resulting from such payment by such Guarantor. In
furtherance of the foregoing, for so long as any Obligations, Letters of Credit
or Commitments remain outstanding, each Guarantor shall refrain from taking any
action or commencing any proceeding against the Company or any other Obligor (or
its successors or assigns, whether in connection with a bankruptcy proceeding or
otherwise) to recover any amounts in respect of payments made under this
Guaranty to any Lender Party.

      2.7 Waiver of Presentments, Etc. Each Guarantor waives all presentments,
demands for performance, notices of nonperformance, protests, notices of
protest, notices of dishonor, and notices of acceptance of this Guaranty and of
the existence, creation, extension or incurring of the Obligations or any new or
additional Obligations or any other indebtedness of Company to any of the Lender
Parties, or the reliance by any Lender Party upon this Guaranty, or the exercise
of any right, power or privilege hereunder.

      2.8 Information Relating to Company. Each Guarantor acknowledges and
agrees that it shall have the sole responsibility for obtaining from the Company
such information concerning the Company's financial condition or business
operations as such Guarantor may require, and that no Lender Party has any duty
at any time to disclose to any Guarantor any information relating to the
business operations or financial condition of the Company.

      2.9 Right of Setoff. In addition to any rights and remedies of the Lender
Parties provided by law, if an Event of Default exists, each Lender Party is
authorized at any time and


                                        4


<PAGE>   184
from time to time, without prior notice to any Guarantor, any such notice being
waived by each Guarantor to the fullest extent permitted by law, to set-off and
apply any and all deposits (general or special, time or demand, provisional or
final) at any time held and other indebtedness at any time owing by such Lender
Party to or for the credit or the account of any Guarantor against any and all
obligations of such Guarantor now or hereafter existing under this Guaranty or
any other Loan Document, irrespective of whether or not the Lender Party shall
have made demand under this Guaranty or any other Loan Document and although
such obligations may be contingent or unmatured. Each Lender Party agrees
promptly to notify the applicable Guarantor and the Agent after any such set-off
and application made by such Lender Party; provided, however, that the failure
to give such notice shall not affect the validity of such set-off and
application. The rights of each Lender Party under this Section 2.9 are in
addition to the other rights and remedies (including without limitation, other
rights of set-off) which such Lender Party may have.

      2.10 Subordination. Any obligations of the Company to any Guarantor, now
or hereafter existing, including but not limited to any obligations to any
Guarantor as subrogee of any Lender Party or resulting from any Guarantor's
performance under this Guaranty, are hereby subordinated to the Obligations and
all other indebtedness (including any interest that would accrue pursuant to the
terms of the Loan Documents or other agreements after commencement of any
Insolvency Proceeding, whether or not allowed as a claim) of the Company to the
Lender Parties. Such obligations of the Company to any Guarantor if the Majority
Banks so request shall be enforced and performance received by such Guarantor as
trustee for the Lender Parties and the proceeds thereof shall be paid over to
the Lender Parties on account of the Obligations, but without reducing or
affecting in any manner the liability of any Guarantor under the other
provisions of this Guaranty. The Lender Parties shall be entitled to enforce all
of such Guarantor's rights with respect to such obligations of the Company to
such Guarantor, including in any Insolvency Proceeding. Any amounts received by
any Guarantor in contravention of this Section 2.10 shall be held in trust for
the benefit of the Lender Parties and shall be paid over or delivered to the
Agent for application to the payment of all Obligations or held as cash
collateral to the extent necessary to give effect to this Guaranty.

      2.11 Reinstatement of Guaranty. If this Guaranty is returned or canceled,
and subsequently any payment or transfer of any interest in property by the
Company to the any Lender Party in fulfillment of any Obligation is rescinded or
must be returned by the Lender Party to the Company, this Guaranty shall be
reinstated with respect to any such payment or transfer, regardless of any such
prior return or cancellation.

      2.12 Powers. It is not necessary for the any Lender Party to inquire into
the powers of the Company or of the officers, directors, partners or agents
acting or purporting to act on its behalf, and any Obligations made or created
in reliance upon the professed exercise of such powers shall be guaranteed
hereunder.

      2.13  Taxes.

            (a) Subject to subsection 2.13(g), any and all payments by any
Guarantor to each Lender Party under this Guaranty or any other Loan Documents
shall be made free and clear of, and without deduction or withholding for, any
and all present or future taxes, levies, imposts, deductions, charges or
withholdings, and all liabilities with respect thereto, excluding, in the case
of each Lender Party, such taxes (including income taxes or franchise taxes) as
are imposed on or measured by each Lender Party's net income by the jurisdiction
under the laws of which such Lender Party is organized or maintains a Lending
Office or any political subdivision thereof (all such non-excluded taxes,
levies, imposts, deductions, charges, withholdings and liabilities being,
hereinafter referred to as "Taxes").

            (b) In addition, each Guarantor shall pay any present or future
stamp or documentary taxes or any other excise or property taxes, charges or
similar levies which arise from any payment made hereunder or from the
execution, delivery or registration of, or otherwise with respect to, this
Guaranty or any other Loan Documents (hereinafter referred to as "Other Taxes").

            (c) Subject to subsection 2.13(g), each Guarantor shall indemnify
and hold harmless each Lender Party for the full amount of Taxes or Other Taxes
(including without limitation, any Taxes or Other Taxes imposed by any
jurisdiction on amounts payable under this Section 2.13) paid by the Lender
Party and any liability (including penalties, interest, additions to tax and
expenses) arising therefrom or with respect thereto, in the amount necessary to
preserve the after-tax yield such Lender Party would have received if such Taxes
or Other Taxes had not been imposed, whether or not such Taxes or Other Taxes
were correctly or legally asserted. Payment under this indemnification shall be
made within 30 days from the date the Lender Party makes written demand
therefor. Should such Lender Party determine in its sole discretion to seek a
refund or rebate of some or all of the amount of Taxes, Other Taxes or other
liability paid by it and for which it was indemnified by a Guarantor and should
it receive some or all of the refund or rebate which it sought, it shall return
to such Guarantor the difference between the amount of such refund or rebate and
its reasonable costs and expenses of counsel (and the allocated cost of internal
counsel) incurred by it in procuring such refund or rebate.

            (d) If any Guarantor shall be required by law to deduct or withhold
any Taxes or Other Taxes from or in respect of any sum payable hereunder to any
Lender Party, then, subject to subsection 2.13(g):

                  (i) the sum payable shall be increased as necessary so that
      after making all required deductions (including deductions applicable to
      additional sums payable under this Section 2.13) such Lender Party
      receives an amount equal to the sum it would have received had no such
      deductions been made;

                  (ii) such Guarantor shall make such deductions; and


                                        6


<PAGE>   186
                  (iii) such Guarantor shall pay the full amount deducted to the
      relevant taxation authority or other authority in accordance with
      applicable law.

            (e) Within 30 days after the date of any payment by any Guarantor of
Taxes or Other Taxes, such Guarantor shall furnish to the affected Lender Party
the original or a certified copy of a receipt evidencing payment thereof, or
other evidence of payment satisfactory to such Lender Party

            (f) Each Lender Party which is a foreign person (i.e., a person
other than a United States person for United States Federal income tax purposes)
agrees that:

                        (i) it shall, no later than the Closing Date (or, in the
      case of a Bank which becomes a Lender Party pursuant to Section 4.1 after
      the Closing Date, the date upon which such Bank becomes a Lender Party)
      deliver to the Guarantor through the Agent:

                  (A) if any Lending Office is located in the United States, two
            accurate and complete signed originals of Internal Revenue Service
            Form 4224 or any successor thereto ("Form 4224"), and

                  (B) if any Lending Office is located outside the United
            States, two accurate and complete signed originals of Internal
            Revenue Service Form 1001 or any successor thereto ("Form 1001"), in
            each case indicating that such Bank is on the date of delivery
            thereof entitled to receive payments of principal, interest and fees
            for the account of such Lending Office or Offices under this
            Guaranty free from withholding of United States Federal income tax;

                        (ii) if at any time any Bank changes its Lending Office
      or Offices or selects an additional Lending Office as herein provided, it
      shall with reasonable promptness deliver to the Guarantor through the
      Agent in replacement for, or in addition to, the forms previously
      delivered by it hereunder:

                  (A) if such changed or additional Lending Office is located in
            the United States, two accurate and complete signed originals of
            Form 4224; or

                  (B) otherwise, two accurate and complete signed originals of
            Form 1001,

in each case indicating that such Bank is on the date of delivery thereof
entitled to receive payments of principal, interest and fees for the account of
such changed or additional Lending Office under this Guaranty free from
withholding of United States federal income tax;


                                        7


<PAGE>   187
                        (iii) it shall, before or promptly after the occurrence
      of any event (including the passing of time but excluding any event
      mentioned in (ii) above) requiring a change in the most recent Form 4224
      or Form 1001 previously delivered by such Bank and if the delivery of the
      same be lawful, deliver to the Guarantor through the Agent two accurate
      and complete original signed copies of Form 4224 or Form 1001 in
      replacement for the forms previously delivered by the Bank; and

                        (iv) it shall, promptly upon any Guarantor's reasonable
      request to that effect, deliver to such Guarantor such other forms or
      similar documentation as may be required from time to time by any
      applicable law, treaty, rule or regulation in order to establish such
      Bank's tax status for withholding purposes.

            (g) No Guarantor will be required to pay any additional amounts in
respect of United States federal income tax pursuant to subsection 2.13(d) to
any Bank for the account of any Lending Office of such Bank:

                        (i) if the obligation to pay such additional amounts
      would not have arisen but for a failure by such Bank to comply with its
      obligations under subsection 2.13(f) in respect of such Lending Office;

                        (ii) if such Bank shall have delivered to such Guarantor
      a Form 4224 in respect of such Lending Office pursuant to subsection
      2.13(f)(i)(A), and such Bank shall not at any time be entitled to
      exemption from deduction or withholding of United States federal income
      tax in respect of payments by such Guarantor hereunder for the account of
      such Lending Office for any reason other than a change in United States
      law or regulations or in the official interpretation of such law or
      regulations by any governmental authority charged with the interpretation
      or administration thereof (whether or not having the force of law) after
      the date of delivery of such Form 4224; or

                        (iii) if the Bank shall have delivered to such Guarantor
      a Form 1001 in respect of such Lending Office pursuant to subsection
      2.13(f)(i)(B), and such Bank shall not at any time be entitled to
      exemption from deduction or withholding of United States Federal income
      tax in respect of payments by such Guarantor hereunder for the account of
      such Lending Office for any reason other than a change in United States
      law or regulations or any applicable tax treaty or regulations or in the
      official interpretation of any such law, treaty or regulations by any
      governmental authority charged with the interpretation or administration
      thereof (whether or not having the force of law) after the date of
      delivery of such Form 1001.

            (h) If any Guarantor is required to pay additional amounts to any
Lender Party pursuant to subsection 2.13(d), then such Lender Party shall use
its reasonable best efforts (consistent with legal and regulatory restrictions)
to change the jurisdiction of its Lending Office so as to eliminate any such
additional payment by such Guarantor which may thereafter accrue if


                                        8


<PAGE>   188
such change in the judgment of such Lender Party is not otherwise significantly
disadvantageous to such Lender Party.

                  (i) The agreements and obligations of each Guarantor contained
in this Section 2.13 shall survive the payment in full of all other Obligations.

      2.14 Continuing Guaranty. This Guaranty is a continuing guaranty and
agreement of subordination and shall continue in effect and be binding upon each
Guarantor until termination of the Commitments, existing of the Letters of
Credit and payment and performance in full of the Obligations which may exist or
which may arise from time to time under successive transactions, and each
Guarantor expressly acknowledges that this Guaranty shall remain in full force
and effect notwithstanding that there may be periods in which no Obligations
exist. This Guaranty supersedes all prior guaranties executed from time to time
by any of the Guarantors in connection with the Second Amended and Restated
Credit Agreement dated as of June 15, 1995, as amended from time to time, among
the Company, the financial institutions party thereto as "Banks" and Bank of
America NT & SA as the Agent for the Banks.

      2.15 Substantial Benefits. The funds that have been borrowed from the
Banks by the Company and the Issuance of any Letter of Credit by the Issuing
Bank have been and are to be contemporaneously used for the benefit of the
Company and the Guarantors. The Company and the Guarantors have derived and will
derive significant and substantial benefits from the accommodations that have
been made by the Banks and the Issuing Bank under the Loan Documents. The
Guarantors have received at least "reasonably equivalent value" (as such phrase
is used in Section 548 of the Bankruptcy Code, in Section 3439.04 of the
California Uniform Fraudulent Transfer Act and in comparable provisions of other
applicable law) and more than sufficient consideration to support its
obligations hereunder in respect of the Obligations and under any of the Loan
Documents to which it is a party.

3. Representations and Warranties. Each Guarantor represents and warrants to the
Lender Parties that (a) such Guarantor and the Company are distinct and separate
entities operating independently; (b) such Guarantor has received copies of the
Credit Agreement and the other Loan Documents and is familiar with and fully
understands of all their respective terms and conditions; (c) no Lender Party
has made any representations or warranties to such Guarantor regarding the
creditworthiness of the Company or the prospects of repayment from sources other
than the Company; (d) this Guaranty is executed at the request of the Company;
(e) such Guarantor has established adequate means of obtaining from the Company
on a continuing basis financial and other information pertaining to the business
of the Company; and (f) such Guarantor is Solvent (both before and after giving
effect to this Guaranty, taking into account such Guarantor's rights of
contribution and indemnity as provided in Section 2.6).

4.     Miscellaneous

      4.1 Participations; Novations. Any Lender Party may from time to time,
without notice to any Guarantor and without affecting any Guarantor's
obligations hereunder, transfer its interest


                                        9


<PAGE>   189
in the Obligations to Participants and Assignees (each as defined in the Credit
Agreement) as provided in the Credit Agreement. Each Guarantor agrees that each
such transfer will give rise to a direct obligation of such Guarantor to each
such Participant and Assignee and that each such Participant and Assignee shall
have the same rights and benefits under this Guaranty as it would have if it
were a Bank party to the Credit Agreement and this Guaranty. Each Lender Party
agrees to maintain the confidentiality of all non-public information provided to
it by any Guarantor or by the Agent on such Guarantor's behalf to the same
extent and with the same exceptions as provided in the Credit Agreement.
Notwithstanding the foregoing, each Guarantor authorizes the Agent and each
other Lender Party to disclose to any prospective Participant and Assignee and
any Participant and Assignee any and all confidential information in the Agent's
and such Lender Party's possession concerning the Guarantor, this Guaranty and
any security for this Guaranty; provided, however, that such Participant or
Assignee or such prospective Participant or Assignee agrees in writing to the
Agent or such Lender Party, as the case may be, to keep such information
confidential to the same extent required by the Lender Parties under the Credit
Agreement.

      4.2 Merger. In the event that (i) one or more Guarantors is merged into
the Company or another Guarantor or (ii) one or more of the Guarantors is sold
or liquidated, subject, in each case, to the provisions of the Credit Agreement,
such Guarantor shall cease to be a Guarantor hereunder without the necessity to
amend or re-issue this Guaranty, and each Guarantor agrees that its obligations
hereunder shall continue in full force and effect hereunder and shall not be
affected by any such merger, sale or liquidation.

      4.3 Waivers, Writing Required. No delay or omission by any Lender Party to
exercise any right under this Guaranty shall impair any such right, nor shall it
be construed to be a waiver thereof. No waiver of any single breach or default
under this Guaranty shall be deemed a waiver of any other breach or default. Any
amendment or waiver of any provision of this Guaranty must be in writing to be
effective.

      4.4 Remedies. All rights and remedies provided in this Guaranty and any
instrument or agreement referred to herein are cumulative and are not exclusive
of any rights or remedies otherwise provided by law. Any single or partial
exercise of any right or remedy shall not preclude the further exercise thereof
or the exercise of any other right or remedy.

      4.5 Costs and Expenses. Each Guarantor agrees to pay to each Lender Party
on demand all costs, expenses and attorneys' fees (including allocated costs for
in-house legal services) incurred by each such Lender Party in connection with
the enforcement of this Guaranty.

      4.6 Section Headings, Interpretation. Section headings are for reference
only, and shall not affect the interpretation or meaning of any provision of
this Guaranty. Unless otherwise provided, references to Articles, Sections and
Exhibits shall be deemed references to Articles, Sections and Exhibits of this
Guaranty. All references to the word "Guarantor" or "the Guarantors" shall mean
all and any one or more of them, as the context shall require.


                                       10


<PAGE>   190
      4.7 Severability. The illegality or unenforceability of any provision of
this Guaranty or any instrument or agreement referred to herein shall not in any
way affect or impair the legality or enforceability of the remaining provisions
of this Guaranty or any instrument or agreement referred to herein.

      4.8   Governing Law and Jurisdiction.

            (a) THIS GUARANTY SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE
WITH, THE LAW OF THE STATE OF CALIFORNIA.

            (b) ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THIS GUARANTY AND
ANY OTHER LOAN DOCUMENTS MAY BE BROUGHT IN THE COURTS OF THE STATE OF CALIFORNIA
OR OF THE UNITED STATES FOR THE NORTHERN DISTRICT OF CALIFORNIA, AND BY
EXECUTION AND DELIVERY OF THIS GUARANTY, EACH GUARANTOR AND EACH LENDER PARTY
CONSENTS, FOR ITSELF AND IN RESPECT OF ITS PROPERTY, TO THE JURISDICTION OF
THOSE COURTS. EACH GUARANTOR AND EACH LENDER PARTY IRREVOCABLY WAIVES ANY
OBJECTION, INCLUDING ANY OBJECTION TO THE LAYING OF VENUE OR BASED ON THE
GROUNDS OF FORUM NON CONVENIENS, WHICH IT MAY NOW OR HEREAFTER HAVE TO THE
BRINGING OF ANY ACTION OR PROCEEDING IN SUCH JURISDICTION IN RESPECT OF THIS
GUARANTY OR ANY DOCUMENT RELATED HERETO. EACH GUARANTOR AND EACH LENDER PARTY
EACH WAIVE PERSONAL SERVICE OF ANY SUMMONS, COMPLAINT OR OTHER PROCESS, WHICH
MAY BE MADE BY ANY OTHER MEANS PERMITTED BY CALIFORNIA LAW.

      4.9 Separate Obligations. This Guaranty creates separate obligations of
each Guarantor in favor of the Lender Parties. The fact that such obligations
are set forth in this one Guaranty rather than in a separate guaranty document
for each Guarantor is for the convenience of the Company and the Guarantors and
shall in no way impair or adversely affect the rights or benefits of any of the
Lender Parties hereunder. Each Guarantor agrees to execute and deliver a
separate agreement, immediately upon request at any time of the Majority Banks,
evidencing such Guarantor's obligations under this Guaranty.

      4.10 Entire Agreement. This Guaranty and any instrument, agreement or
document attached hereto or referred to herein (a) integrate all the terms and
conditions mentioned herein or incidental hereto, (b) supersede all oral
negotiations and prior writings with respect to the subject matter hereof, and
(c) are intended by the parties as the final expression of the agreement with
respect to the terms and conditions set forth in this Guaranty and any such
instrument, agreement and document and as the complete and exclusive statement
of the terms agreed to by the parties. In the event of any conflict between the
terms, conditions and provisions of this Guaranty and any such instrument,
agreement or document, the terms, conditions and provisions of this Guaranty
shall prevail.

Agreement. I am rendering this opinion pursuant to subsection 5.01 (c) of the
Credit Agreement. Except as otherwise defined herein, capitalized terms used but
not defined herein shall have the meanings given to them in the Credit
Agreement.

      As used herein, the term "Loan Documents" shall mean the Credit Agreement
and the Guaranty.

      I am admitted to practice law only in the State of California, and I
express no opinion concerning any law other than the law of the State of
California, the Delaware General Corporation law, the law of the United States
of America, and, to the extent necessary to render my opinion in paragraphs
l(b), l(d), l(e), l(f), the second sentence of paragraph 3 and paragraphs 5(d),
6 and 8, the Colorado Corporations Code, the Utah Revised Business Corporations
Act, the Wyoming Business Corporations Act and the Texas Business Corporation
Act. In so far as the opinions contained herein purport to relate to the
Delaware General Corporation Law, the Colorado Corporations Code, the Utah
Revised Business Corporations Act, the Wyoming Business Corporations Act and the
Texas Business Corporation Act (collectively, the "Laws"), I have relied on such
Laws as reported in standard compilations.

      In rendering this Opinion, I have assumed the genuineness and authenticity
of all signatures (other than that of Borrower and each Subsidiary) on original
documents; the authenticity of all documents submitted to me as originals; the
conformity of originals to all documents submitted to me as copies; the
accuracy, completeness and authenticity of certificates of public officials; the
due authorization, execution and delivery of all documents (except the due
authorization, execution and delivery by Borrower of the Credit Agreement and by
each Subsidiary of the Guaranty) where authorization, execution and delivery are
prerequisites to the effectiveness of such documents; the power and authority of
the Banks to enter into and perform their obligations under the Loan Documents;
that the Banks are duly qualified in the State of California to do business of
the type contemplated by the Loan Documents; that each of the Banks qualifies
for the exemption from the otherwise applicable interest rate limitations of
California law for loans or forbearances by, as the case may be, (i) national
banks provided by Article XV, Section 1 of the California Constitution or (ii)
certain "foreign (other nation) banks" provided by California Financial Code
Section 1716 or (iii) state banks provided by Article XV, Section 1 of the
California Constitution; that all loans under the Credit Agreement will be made
by the Banks for their own accounts or for the account of another person or
entity that qualifies for an exemption from the interest rate limitations of
California law, and there is no present agreement or plan, express or implied,
on the part of the Banks to sell participations or any other interest in the
loans to be made under the Credit Agreement to any person or entity other than a
person or entity that also qualifies for an exemption from the interest rate
limitations of California law; and with

respect to matters of fact (as distinguished from matters of law), I also have
relied upon and assumed that the representations of the Borrower and each
Subsidiary and the other parties set forth in the Loan Documents and any other
certificates, instruments or agreements executed in connection therewith or
delivered to me are true, correct, complete and not misleading, although to my
knowledge the representations of the Borrower and each Subsidiary set forth in
the Loan Documents and any such other certificates, instruments and agreements
are true, correct, complete and not misleading. I have also assumed that all
individuals executing and delivering documents on behalf of the Banks and Agent
had the legal capacity to so execute and deliver and that the Loan Documents are
obligations binding upon Banks and Agent.

      With respect to my opinions in paragraph 4(c) and 5(c) below, I have
relied solely upon copies, supplied to me by the Borrower or a Subsidiary, of
each undertaking, contract, indenture, mortgage, deed of trust or other
instrument, document or agreement listed in Exhibit A, (i) of the Borrower
listed on the Index to Form 10K Exhibits to the Borrower's Annual Report on Form
10K for the fiscal year ending December 31, 1996 and (ii) of the Borrower
involving amounts in excess of $50,000,000 to which Borrower or any Subsidiary
is a party or by which Borrower or any Subsidiary is bound.

      In rendering my opinion in paragraph 6, I have relied solely on a
certificate of good standing from each of the Secretary of State's office of
each of the states listed below the Borrower's and each Subsidiary's name on
Exhibit B.

      Where I render an opinion "to the best of my knowledge" or concerning an
item "known to me" or my opinion otherwise refers to my "knowledge," it is
intended to indicate that during the course of my representation of Borrower and
the Subsidiaries, no information that would give me current actual knowledge of
the inaccuracy of such statement has come to my attention in rendering legal
services to Borrower or the Subsidiaries.

      On the basis of the foregoing, in reliance thereon, and with the foregoing
qualifications, I am of the opinion that:

      1. (a) Borrower is a corporation, duly incorporated and validly existing
under the laws of Delaware and has the requisite corporate power and authority
to own its property and to conduct the business in which it is currently
engaged. (b) Wilcott is a corporation duly incorporated and validly existing
under the laws of Colorado and has the requisite corporate power and authority
to own its property and to conduct the business in which it is currently
engaged. (c) Each of GCC, SR91, GILC and Desert is a corporation duly
incorporated and


<PAGE>   240
Bank of America National Trust and Savings Association,
for itself and as Agent
June 30, 1997
Page 4


validly existing under the laws of California and has the requisite corporate
power and authority to own its property and to conduct the business in which it
is currently engaged. (d) Each of G.G. & R., Intermountain, and Pozzolan is a
corporation duly incorporated and validly existing under the laws of Utah and
has the requisite corporate power and authority to own its property and to
conduct the business in which it is currently engaged. (e) Bear River is a
corporation duly incorporated and validly existing under the laws of Wyoming and
has the requisite corporate power and authority to own its property and to
conduct the business in which it is currently engaged. (f) GTC is a corporation
duly incorporated and validly existing under the laws of Texas and has the
requisite corporate power and authority to own its property and to conduct the
business in which it is currently engaged. (g) GILC, L.P. and SR91, L.P. are
California limited partnerships validly existing under the laws of California
and each has the requisite partnership power and authority to own its property
and to conduct the business in which it is currently engaged.

      2. Borrower (a) has taken all necessary and appropriate corporate action
to authorize the execution, delivery and performance of the Credit Agreement,
and (b) has the corporate power and authority to execute, deliver and perform
the Credit Agreement. Each Subsidiary (a) has taken all necessary and
appropriate corporate action or partnership action, as applicable, to authorize
the execution, delivery and performance of the Guaranty, and (b) has the
corporate power or partnership power, as applicable, and authority to execute,
deliver and perform the Guaranty.

      3. The Credit Agreement has been duly executed and delivered by the
Borrower. The Guaranty has been duly executed and delivered by each of the
Subsidiaries. The Credit Agreement constitutes a legal, valid and binding
obligation of Borrower, enforceable against Borrower in accordance with its
terms. The Guaranty constitutes a legal, valid and binding obligation of each
Subsidiary, enforceable against each Subsidiary in accordance with its terms.

      4. The execution, delivery and performance by Borrower of the Credit
Agreement do not (a) violate or contravene any injunction, order, writ,
judgment, decree, determination or award of any United States or California
Governmental Authority as presently in effect applicable to Borrower; (b)
conflict with or result in a breach of or constitute a default under the
certificate of incorporation and bylaws of Borrower; (c) violate or result in a
breach of or constitute any default under any agreements of Borrower set forth
in Exhibit A, and, do not result in or require the creation or imposition of any
lien on any of Borrower's properties or revenues pursuant to any injunction,
order, decree or undertaking as presently in effect or any such agreements of
Borrower set forth in Exhibit A; or (d) result in or require the creation or
imposition of any lien on any of its properties or revenues pursuant to any
provision of any law, rule or regulation as presently in effect.

      5. The execution, delivery and performance by each Subsidiary of the
Guaranty do not (a) violate or contravene any injunction, order, writ judgment,
decree, determination or award of any United States or California Governmental
Authority as presently in effect applicable to each Subsidiary; (b) conflict
with or result in a breach of or constitute a default under the
articles/certificates of incorporation and bylaws or partnership agreement, as
applicable, of each Subsidiary: (c) violate or result in a breach of or
constitute any default under any agreements of each Subsidiary set forth in
Exhibit A, and do not result in or require the creation or imposition of any
lien on any Subsidiary's its properties or revenues pursuant to any injunction,
order, decree or undertaking as presently in effect or any such agreements of
each Subsidiary; or (d) result in or require the creation or imposition of any
lien on any of its properties or revenues pursuant to any provision of any law,
rule or regulation as presently in effect.

      6. Each of Borrower, and the Subsidiaries is duly qualified to do business
and is in good standing in the states listed below its name on Exhibit B hereto.

      7. No authorization, consent, approval, license, qualification or formal
exemption from, nor notice to, nor any filing, recordation, declaration or
registration with, any United States or California Governmental Authority, or to
my knowledge any other Governmental Authority, is necessary or required on the
part of Borrower in connection with the execution, delivery, or performance by
Borrower of the Credit Agreement.

      8. No authorization, consent, approval, license, qualification or formal
exemption from, nor notice to, nor any filing, recordation, declaration or
registration with any United States or California Governmental Authority, or to
my knowledge any other Governmental Authority, is necessary or required on the
part of each Subsidiary in connection with the execution, delivery, or
performance by each Subsidiary of the Guaranty.

      9. To the best of my knowledge, there is no claim, dispute, injunction,
temporary restraining order, action, litigation, investigation or proceeding
pending or threatened against Borrower before any court, arbitrator,
administrative agency or Governmental Authority of any kind (a) with respect to
the Credit Agreement or (b) which, if adversely determined, would have a
Material Adverse Effect.

      10. To the best of my knowledge, there is no claim, dispute, injunction,
temporary restraining order, action, litigation, investigation or proceeding
pending or threatened against any Subsidiary before any court, arbitrator,
administrative agency or Governmental Authority of any kind (a) with respect to
the Guaranty or (b) which, if adversely determined, would have a Material
Adverse Effect.

      11. Neither the Borrower nor any Subsidiary is an "investment company" or
a company "controlled" by an "investment company," within the meaning of the
Investment Company Act of 1940, as amended. Neither the Borrower nor any
Subsidiary is subject to regulation under the Public Utility Holding Company Act
of 1935, the Interstate Commerce Act (49 U.S.C Sections 10101 et seq. (Supp.
1992) or the Federal Power Act which would limit its ability to incur
Indebtedness.

      12. Neither the Borrower nor any Subsidiary is generally engaged in the
business of purchasing or selling Margin Stock or extending credit for the
purpose of purchasing or carrying Margin Stock. The aggregate value of all
Margin Stock directly or indirectly owned by the Borrower and its Subsidiaries
is less than 25% of the aggregate value of the consolidated assets of the
Borrower and its Subsidiaries.

      13. The only subsidiaries of Borrower are the Subsidiaries and Granite
SR91 L.P., a limited partnership, of which Granite SR91 Corporation is the
general partner and the Borrower is the sole limited partner.

      The opinions expressed in this letter are qualified to the extent that the
validity, binding nature or enforceability of any provisions of the Loan
Documents may be limited or otherwise affected by:

      a. The effects of bankruptcy, insolvency, reorganization, fraudulent
conveyance, moratorium, or other similar laws now or hereafter in effect
limiting the validity or enforceability of creditor's rights and remedies
generally;

      b. General principles of equity, regardless of whether considered in
proceedings in equity or at law;

      c. The covenant of good faith and fair dealing implied in every agreement
under common law (and to similar provisions of federal law, where applicable);
and

      d. The effect of any law or legal principle which provides that a court
may refuse to enforce, or may limit the application of; a contract or any clause
thereof which the court finds as a matter of law to have been unconscionable at
the time it was made.

      e. The opinions expressed in this letter are further qualified to the
extent that the validity, binding nature or enforceability of any provisions of
the Loan Documents may be limited or otherwise affected by:

            i. The unenforceability under certain circumstances under California
or


<PAGE>   243
Bank of America National Trust and Savings Association,
for itself and as Agent
June 30, 1997
Page 7


federal law or court decisions of provisions (i) releasing a party against
liability for wrongful or negligent acts, (ii) indemnifying a party to the
extent that the events giving rise to the indemnity arise in whole or in part
from the wrongful or negligent acts of the indemnitee, or (iii) where such
release or indemnification is contrary to public policy, including but not
limited to indemnification and/or releases relating to any issues of securities
laws;

            ii. The effect of California Civil Code Section 1717 and other
applicable statutes and judicial decisions which provide, among other things,
that a court may limit the granting of attorneys' fees to those attorneys' fees
which are determined by the court to be reasonable and that attorneys' fees may
be granted only to a prevailing party and that a contractual provision for
attorneys' fees is deemed to extend to both parties (notwithstanding that such
provision by its express terms benefits only one party);

            iii. The assumption that if the Agent or the Banks enforce their
remedies, they will do so in a commercially reasonable manner;

            iv. The effect of California court decisions invoking statutes or
principles of equity which have held that certain covenants and provisions of
agreements are unenforceable where (i) the breach of such covenants or
provisions imposes restrictions or burdens upon the debtor, including the
acceleration of indebtedness due under debt instruments, and it cannot be
demonstrated that the enforceability of such restrictions or burdens is
reasonably necessary for the protection of the creditors, or (ii) the creditor's
enforcement of such covenants or provisions under the circumstances would
violate the creditor's implied covenants of good faith and fair dealing;

            v. The unenforceability under certain circumstances of contractual
provisions self-help or summary remedies; and

            vi. Decisions by California courts admitting evidence extrinsic to a
written agreement between the parties thereto that the parties intended a
meaning contrary to that expressed by the parties in writing.

      The foregoing opinions are also subject to the following additional
assumptions, limitations, qualifications and exceptions:

      a. Provisions in the Loan Documents requiring Borrower or any Subsidiary
to execute, in the future, additional instruments and documents may be
unenforceable.

      b. Any provision contained in the Loan Documents that purports to require
that any action or decision of Agent or Banks is conclusively binding upon
Borrower or any


<PAGE>   244
Bank of America National Trust and Savings Association,
for itself and as Agent
June 30, 1997
Page 8


Subsidiary may be unenforceable.

      c. You are advised that any provision in the Loan Documents purporting to
waive, limit or restrict the right of Borrower or Subsidiary to offset against
obligations owing under the Loan Documents may not be enforceable.

      d. Those provisions in the Loan Documents imposing late charges (interest
or otherwise) and/or additional interest in the event of default are governed by
the rules relating to "liquidated damages" as set forth in California Civil Code
Sections 1671 et seq., and relevant case law (see, e.g., Garrett v. Coast and
Southern Federal Savings & Loan, 9 Cal.3d 731 (1973)). I express no opinion as
to the effect of judicial decisions and statutes limiting the enforceability of
provisions imposing penalties, forfeitures, late payment charges, an increase in
interest rate, or payment of other additional consideration, (i) upon
prepayment, late payment, maturity, default or a lender's election to accelerate
a loan, particularly in cases where the occurrence of a default or waiving the
benefit of a statutory right bears no reasonable relation to the damage suffered
by the lender or is otherwise held to be a penalty; or (ii) as a consequence of
costs incurred by the lender or imposition of governmental charges, taxes,
levies or requirements upon a lender.

      e. Those provisions in the Loan Documents requiring the consent of Agent
and Banks or allowing Agent or Banks to take certain actions may be interpreted
by a court to contain an implied covenant of reasonableness and/or fair dealing
(see, e.g., Kendall v. Pestana, 40 Cal.3d 488 (1985); Cohen v. Ratinoff, 147
Cal.App.3d 321 (1983)).

      f. You should be aware of the unenforceability, under certain
circumstances, of provisions waiving broadly or vaguely stated rights or unknown
future rights, or rights which may not be waived on statutory or public policy
grounds, or provisions stating that rights or remedies are not exclusive, that
every right or remedy is cumulative and may be exercised in addition to or with
any other right or remedy or that the election of some particular remedy or
remedies does not preclude recourse to one or more others.

      g. You should be aware of limitations based on public policy on provisions
stating that a borrower's obligations are unaffected by reason of any default or
failure on the part of a lender to perform or comply with the terms of the
subject loan documents.

      h. I express no opinion as to the enforceability of the consent to
service, jurisdiction or forum of any claim, demand, action or cause of action
arising under or related to the Loan Documents or the transactions contemplated
therein.

      i. I express no opinion as to the enforceability of any right of any
creditor to


<PAGE>   245
Bank of America National Trust and Savings Association,
for itself and as Agent
June 30, 1997
Page 9


collect any payment due under the Loan Documents to the extent that such payment
constitutes a penalty or forfeiture.

      j. I express no opinion as to the enforceability of provisions in the Loan
Documents creating presumptions or creating rights of set-off.

      k. I express no opinion on the accuracy of any representations or
warranties of Borrower or any Subsidiary. Furthermore I express no opinion as to
the survivability of any warranties, indemnities or other obligations.

      l. I express no opinion as to the enforceability of those provisions in
the Loan Documents purporting to appoint the Agent or Banks as attorney-in-fact
for Borrower or to grant an irrevocable power of attorney to Agent or Banks.

      m. I express no opinion as to the enforceability of provisions in the Loan
Documents purporting to provide that any approval, consent, authorization or
satisfaction required of Agent or Banks or any notice given by or other action
taken by Agent or Banks under the Loan Documents shall be presumed to be
reasonable.

      n. I express no opinion as to the effect of laws and judicial decisions
that provide that in certain circumstances a surety may be exonerated if the
creditor materially alters the original obligation of the principal without the
surety's consent, or otherwise takes any action without notifying the surety
that materially prejudices the surety.

      o. I express no opinion as to any securities, anti-trust, tax, land use,
safety, environmental, hazardous materials, insurance company or banking laws,
rules or regulations, or laws, rules or regulations applicable to Agent or
Banks.

      p. I express no opinion as to any provision providing for the exclusive
jurisdiction of a particular court or purporting to waive rights to trial by
jury, service of process or objections to the laying of venue or to forum on the
basis of forum non conveniens in connection with any litigation arising out of
or pertaining to the Loan Documents.

      q. I express no opinion as to the effect of California Civil Code Section
1698 and similar statutes and federal laws and judicial decisions (a) providing
that oral modifications to a contract or waivers of contractual provisions may
be enforceable, if the modification was performed, notwithstanding any express
provision in the agreement that the agreement may only be modified or an
obligation thereunder waived in writing, or (b) creating an implied agreement
from trade practices or course of conduct.

      r. I express no opinion as to the effect of certain rights, remedies and
waivers contained in the Loan Documents being limited or rendered ineffective by
applicable statutory law or judicial decisions governing such provisions, but
such laws and judicial decisions do not render the Loan Documents unenforceable
as a whole, and there exists, in the Loan Documents and pursuant to applicable
law, legally adequate remedies for realization of the principal benefits
purported to be afforded by the Loan Documents.

      s. With respect to my opinions expressed in paragraphs 4(d), 5(d), 7 and
8, I have not conducted any special investigation of statutes laws, rules or
regulations and my opinion with respect thereto are limited to such Laws that to
my knowledge and as in my experience are of general application to transactions
of the sort contemplated by the Loan Documents.

      I further advise you that:

      a. The enforceability of the Guaranty against a Subsidiary may be subject
to California statutory provisions and case law to the effect that a guarantor
may be exonerated if the beneficiary of the guaranty alters the original
obligation of the principal, fails to inform the guarantor of material
information pertinent to the principal or any collateral, elects remedies that
may impair the subrogation rights of the guarantor against the principal or that
may impair the value of the collateral, fails to accord the guarantor the
protections afforded a debtor under the Uniform Commercial Code or otherwise
takes any action that materially prejudices the guarantor unless, in any such
case, the guarantor validly waives such rights or the consequences of any such
action. See e.g., California Civil Code Section 2799 through Section 2855;
Sumitomo Bank of California v. Iwasaki, 70 Cal. 2d 81, 73 Cal. Rptr. 564 (1968);
Union Bank v. Gradsky, 265 Cal. App. 2d 40, 71 Cal. Rptr 64 (1968); Connolly v.
Bank of Sonoma County, 184 Cal. App. 3d 1119, 229 Cal Rptr. 396 (1986); C.I.T.
Corp. v. Anwright Corp., 191 Cal. App. 3d 1420, 237 Cal. Rptr. 108 (1987);
American National Bank v. Perma-Tile Roof Co., 200 Cal. App. 3d 889, 246 Cal
Rptr. 381 (1988); In re Kirkland, 915 F.2d 1236 (9th Cir. 1990); and Cathay Bank
v. Lee, 18 Cal. Rptr. 2d 420 (1993). While express and specific waivers of a
guarantor's right to be exonerated, such as those contained in the Guaranty, are
generally enforceable under California law, we express no opinion as to whether
the Guaranty contains an express and specific waiver of each exoneration defense
a guarantor might assert or as to whether each of the waivers contained in the
Guaranty is fully enforceable.

b. It could be contended that the Guaranty has not been given for a fair or
reasonably equivalent consideration, that a Subsidiary is, or, by entering into
the Guaranty may become, insolvent, and that the Guaranty may be voidable by
creditors of a Subsidiary or by a trustee or receiver of a Subsidiary in
bankruptcy or similar proceedings pursuant to


<PAGE>   247
Bank of America National Trust and Savings Association,
for itself and as Agent
June 30, 1997
Page 11


applicable bankruptcy, fraudulent conveyance or similar laws. Because of these
possible contentions, my opinions are further limited by and subject to the
effect of such laws.

      This opinion is intended solely for the benefit of the Agent, and the
Banks and their Assignees and Participants, as defined in Section 11.07 of the
Credit Agreement, and is not to be made available to or relied upon by any other
person, firm, or entity, other than regulatory authorities in connection with
bank examinations, without our prior written consent.


                                Very truly yours,

                     FIRST AMENDMENT TO THE CREDIT AGREEMENT

           THIS FIRST AMENDMENT TO THE CREDIT AGREEMENT (this "Amendment"), is
entered into as of January 16,1998, by and among GRANITE CONSTRUCTION
INCORPORATED, a Delaware corporation, (the "Company"), the Banks signatory
hereto and BANK OF AMERICA NATIONAL TRUST AND SAVINGS ASSOCIATION, as Issuing
Bank and as agent for itself and the Banks (in such capacity, the "Agent").


                                    RECITALS


       A.     The Company, the several financial institutions named as "Banks"
therein, the Issuing Bank and the Agent are parties to a Credit Agreement dated
as of June 30, 1997 (the "Prior Credit Agreement"). The Prior Credit Agreement,
as amended by this Amendment, is herein referred to as the "Credit Agreement."
Unless otherwise defined herein, all capitalized terms used in this Amendment
shall have the respective meanings assigned to them in the Credit Agreement.

       B.     Pursuant to the Prior Credit Agreement, the Banks have extended
and are continuing to extend certain credit facilities to the Company.

       C.     The Company has informed the Agent and the Banks that the Company
and certain of its Subsidiaries propose to issue in one or more private
placements unsecured notes (collectively, the "Private Placement Notes"). Any
Private Placement Notes issued by the Company may be unconditionally guaranteed
by Subsidiaries of the Company. The proceeds of the Private Placement Notes are
to be used for general corporate purposes.

       D.     The Company has requested that the Majority Banks and the Agent
agree to amend the Prior Credit Agreement to permit the Company and its
Subsidiaries to incur up to $100,000,000 in additional Indebtedness and to
permit the Subsidiaries of the Company to guaranty up to $100,000,000 of such
Indebtedness incurred by the Company. The Majority Banks and the Agent are
willing to agree to such request, but only on the terms, conditions and
understandings as set forth herein.

                                    AGREEMENT

       THEREFORE, for valuable consideration, the receipt and adequacy of which
are hereby acknowledged, the parties hereto agree as follows:

       1.     Amendments to Prior Credit Agreement. The Prior Credit Agreement
is hereby amended as follows:

              (a)    Section 8.06 of the Prior Credit Agreement is hereby
amended by deleting "or" where it appears at the end of subsection (h) thereof,
by deleting "." where it appears at the end of subsection (I) thereof and
substituting in its place "; or" and by inserting immediately after subsection
(I) thereof the following:

                     (i)    guaranties by one or more Subsidiaries of the
              Company of obligations of the Company in an aggregate amount
              outstanding not to exceed $100,000,000.


<PAGE>   2

              (b)    Section 8.18 of the Prior Credit Agreement is hereby
amended by deleting "and" where it appears at the end of subsection (g) thereof,
by deleting "." where it appears at the end of subsection (h) thereof and
substituting in its place "; and" and by inserting immediately after subsection
(h) thereof the following:

                     (i)    Indebtedness (including Guaranty Obligations
              permitted pursuant to subsection 8.06(j)) in an aggregate amount
              outstanding not to exceed $100,000,000.

       2.     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 exists.

              (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 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 business judgment, without reliance upon the Agent, any Bank or any
other Person.

       3.     Effective Date. This Amendment will become effective as of the
date first written above (the "Effective Date"), provided that each of the
following conditions precedent has been and remains satisfied on such date:

              (a)    The Agent has received in sufficient number for each Bank,
duly executed originals (or an executed facsimile copy, to be followed promptly
by delivery of executed originals):

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

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

              (b)    all representations and warranties contained (or
       incorporated by reference) herein are true and correct as of the
       Effective Date.

       4.     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 to the 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)    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.

              (f)    The execution and delivery by the Agent and the Banks of
this Amendment shall not be deemed to 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.

              (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)    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.

              (i)    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.

                               SIXTH AMENDMENT TO

                                       THE

                         GIBBONS COMPANY PROFIT SHARING

                               AND RETIREMENT PLAN


           This Sixth Amendment to the Gibbons Company Profit Sharing and
Retirement Plan (the "Plan") is made and entered into this 30th day of May ,
1997, 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; and

           WHEREAS, the Internal Revenue Service has requested that certain
technical amendments be made to the Plan as a condition for the issuance of a
favorable determination letter relating to the qualified status of the Plan
under the Internal Revenue Code of 1986, as amended, and the regulations
thereunder.

           NOW, THEREFORE, in consideration of the foregoing premises, GG&R
amends the following Sections of the Plan (or portions thereof) generally
effective as of January 1, 1989, unless otherwise noted therein:


                     2.30 "K-TEST AVERAGE CONTRIBUTION PERCENTAGE" shall mean
           the average (expressed as a percentage) of the K-Test Contribution
           Percentages of the Participants in a group.





                                        1

<PAGE>   2

                     2.31 "K-TEST CONTRIBUTION PERCENTAGE" shall mean the ratio
           (expressed as a percentage) of a Participant's K-Test Contributions
           for a Plan Year to the Participant's Compensation for the Plan Year.
           The K-Test Contribution Percentage for a Participant who is a Highly
           Compensated Employee shall be determined by combining all cash or
           deferred arrangements under which the Highly Compensated Employee is
           eligible to participate (other than those which may not be
           permissively aggregated) with this Plan as though they were a single
           arrangement. If a Highly Compensated Employee is eligible to
           participate in this Plan and the family aggregation rules in Section
           2.22 apply, then the K-Test Contribution shall be determined by
           combining the K-Test Contributions and compensation of all eligible
           Family Members. For this purpose, Compensation is defined as in
           Section 7.01(b) of the Plan. The K-Test Contribution Percentage for a
           Participant who has made no Elective Deferral contributions and who
           is not credited with any K-Test Contributions for the Plan Year shall
           be zero (0).

                     2.32 "K-TEST CONTRIBUTIONS" shall mean, for any Plan Year,
           a Participant's Elective Deferrals, plus, if so elected by the
           Employer, part or all of the Qualified Non-Elective Contributions and
           Qualified Matching Contributions allocated to the Participant for
           such year, provided that, any Qualified Non-Elective Contributions
           included as K-Test Contributions shall not increase the difference
           between the K-Test Average Contribution Percentage for Highly
           Compensated Employees and the K-Test Average Contribution Percentage
           for Non-Highly Compensated Employees; and, further provided that, no
           Qualified Non-Elective Contributions or Qualified Matching
           Contributions included as K-Test Contributions shall be included as
           M-Test Contributions. In determining the amount of a Participant's
           Elective Deferrals under this Section, the Plan Administrator shall
           take into account elective deferrals made by the Participant under
           any other plan which is aggregated with this Plan for purposes of
           Code Section 401(a)(4) or Code Section 410(b) (other than Code
           Section 410(b)(2)(A)(ii)) and any other plan satisfying Code
           Section 401(k)(3) and Reg. Section 1.401(k)-1(b)(3) which the 
           Employer elects to permissively aggregate with this Plan, by 
           treating all such plans and this Plan as a single plan.

                     2.35 "M-TEST AVERAGE CONTRIBUTION PERCENTAGE" shall mean
           the average (expressed as a percentage) of the M-Test Contribution
           Percentages of the Participants in a group.

                     2.36 "M-TEST CONTRIBUTION PERCENTAGE" shall mean the ratio
           (expressed as a percentage) of a Participant's M-Test Contributions
           for a Plan Year to the Participant's Compensation for the Plan Year.
           The M-Test Contribution Percentage for a Participant who is a Highly
           Compensated Employee shall be determined by combining all plans
           subject to Code Section 401(m) under which the Highly Compensated
           Employee is eligible to participate (other than those which may not
           be permissively aggregated) with this Plan as though they were a
           single plan. If a Highly Compensated Employee is eligible to



                                        2

<PAGE>   3

           participate in this Plan and the family aggregation rules in Section
           2.22 apply, then the M-Test Contribution Percentage shall be
           determined by combining the M-Test Contributions and compensation of
           all eligible Family Members. For this purpose, Compensation is
           defined as in Section 7.01(b) of the Plan. The M-Test Contribution
           Percentage for a Participant who has made no Elective Deferral
           contributions and who is not credited with any M-Test Contributions
           for the Plan Year shall be zero (0).

                     2.37 "M-TEST CONTRIBUTIONS" shall mean for any Plan Year
           Matching Contributions made pursuant to Section 5.06 less any of the
           Participant's Qualified Matching Contributions included as K-Test

           provided that, no Qualified Non-Elective Contributions included as

           contributions made by the Participant and all matching contributions
           made by the Employer under any other plan which is aggregated with
           this Plan for purposes of Code Section 401(a)(4) or Code Section 
           410(b) (other than Code Section 410(b)(2)(A)(ii) and any other plan
           satisfying Code Section 401(k)(3) and Reg. Section 1.401(k)-1(b)(3)
           which the Employer elects to permissively aggregate with this Plan,
           by treating all such plans and this Plan as a single plan.

           deemed to be a Participant in the Plan for purposes of any applicable
           non-discrimination test, including the K-Test and M-Test defined in
           this Plan, without regard to whether he has executed a Salary
           Reduction Agreement and agreed to have contributions made to this
           Plan through Elective Deferrals. Effective July 1, 1993, a
           Participant who is not also a Davis-Bacon Employee or a Salaried
           Employee may nevertheless be considered "active or inactive"
           depending on whether he has signed a Salary Reduction Agreement.

           contributed to the Plan and (if treated as K-Test Contributions) the
           requirements of

           (c) are met or (if treated as M-Test Contributions) the requirements
           of Reg. Section 1.401(m)-1(b)(5) are met.

                                 (A). For this purpose, a Participant's Elective

                     -  -  -

                      (d)        EXCESS COMBINED-TEST CONTRIBUTIONS (K-TEST):
                                 With respect to any Plan Year, the excess of
                                 the aggregate amount of the K-Test
                                 Contributions actually made on behalf of Highly
                                 Compensated Employees for such Plan Year over
                                 the maximum amount of such contributions
                                 permitted under Section 5.12(d), provided that
                                 M-Test Contributions are not reduced. The
                                 Excess Combined-Test Contributions of an
                                 individual Highly Compensated Employee shall be
                                 determined in the same manner as Excess K-Test

                                 disregarding the provision for taking into

                                 individual Highly Compensated Employee shall be
                                 determined in the same manner as Excess M-Test
                                 Contributions under (c) above.

                     5.14 CORRECTION OF EXCESS CONTRIBUTIONS: For Plan Years
           commencing after December 31, 1986, the Plan provides the following
           methods for correcting excess contributions as described in Section
           5.09:

                      -  -  -

                      (b)        EXCESS K-TEST CONTRIBUTIONS: The Plan
                                 Administrator shall direct the Trustee to
                                 distribute to a Participant his Excess K-Test
                                 Contribution plus income, if any, allocable
                                 thereto. Such distribution shall be designated
                                 by the Plan Administrator as a distribution of
                                 an excess contribution and shall be made after
                                 the end of the Plan Year in which the excess
                                 contribution arose and within twelve (12)
                                 months after the end of such Plan Year.

                                 If the Employer has made a Matching
                                 Contribution attributable to any portion of the
                                 Participant's Excess K-Test Contribution
                                 distributed to the Participant pursuant to the
                                 above, the Plan Administrator shall treat such
                                 Matching Contribution in the same manner as an
                                 Excess M-Test Contribution in accordance with
                                 (C) below. For the Plan Year commencing on
                                 January 1, 1994, if the Employer has made a
                                 Matching Contribution attributable to any
                                 portion of the Participant's Excess K-Test
                                 Contribution distributed to the Participant
                                 pursuant to the above, the Plan Administrator
                                 shall treat such Matching Contribution as a
                                 forfeiture. The forfeited amount shall be used
                                 to reduce the Employer's Matching Contribution
                                 otherwise required for the Plan Year.

                      (c)        EXCESS M-TEST CONTRIBUTIONS: The Plan
                                 Administrator shall direct the Trustee to
                                 distribute to a Participant any portion of the
                                 Participant's Excess M-Test Contribution, plus
                                 income, if any, allocable thereto. Such
                                 distribution shall be designated by the Plan
                                 Administrator as a distribution of excess
                                 contributions and shall be made after the end
                                 of the Plan Year in which the excess
                                 contribution arose and within twelve (12)
                                 months after the end of such Plan Year.

                      (d)        EXCESS COMBINED-TEST CONTRIBUTIONS: The Plan
                                 Administrator shall correct the Excess
                                 Combined-Test Contributions (K-Test or M-Test)
                                 in the same manner as for Excess K-Test and
                                 M-Test Contributions in (b) and (c) above. In
                                 order to satisfy the Combined Test Limitations
                                 the Plan Administrator shall reduce K-Test
                                 Contributions, M-Test Contributions or both for
                                 all affected Highly Compensated Employees. The
                                 Plan

                                 Administrator shall make reductions which
                                 result in the least amount of contributions
                                 returned.

           For purposes of the above, income shall include realized and
           unrealized gains and losses and shall be allocated to excess
           contributions in accordance with Regulations issued by the Secretary.
           Distributions pursuant to the above shall be made without regard to
           any consent by the Participant or Spouse otherwise required under
           this Plan.

                     19.03     TOP-HEAVY MINIMUM REQUIRED ALLOCATION:  For any
           Plan Year in which the Plan is Top-Heavy, but not Super Top-Heavy:

                     -  -  -

                      (2)        In the case where the Employer has no defined
                                 benefit plan which designates this Plan to
                                 satisfy Code Section401 and 416(c), the largest
                                 percentage of Employer contributions and
                                 forfeitures, as a percentage of the first two
                                 hundred thousand dollars ($200,000), (or such
                                 large amount as may be prescribed by the
                                 Secretary of Treasury or his delegate) of the
                                 Key Employee's top-Heavy Compensation,
                                 allocated on behalf of any Key Employee for
                                 that year. In calculating this percentage all
                                 amounts contributed by the Employer to the Key
                                 Employee's Elective Deferral Account pursuant
                                 to a Salary Reduction Agreement shall be
                                 treated as Employer contributions. For Plan
                                 Years beginning after December 31, 1993, the
                                 Plan shall substitute the amount "one hundred
                                 fifty thousand dollars ($150,000)" for the
                                 amount "two hundred thousand dollars
                                 ($200,000)" wherever it appears in this
                                 Section. The one hundred fifty thousand dollar
                                 amount shall be adjusted each Plan Year as
                                 provided in Code Section40l(a)(17(B).

<PAGE>   23
title insurance policies, opinions, abstracts, and surveys in the possession of
the Company or the Associated Companies and relating to such property or
interests. The Associated Companies own (with good and marketable title in the
case of real property, subject only to the matters permitted by the following
sentence) all the properties and assets (whether real, personal, or mixed and
whether tangible or intangible) which the Company purports to own on Part 3.7 of
the Disclosure Schedule and reflected as owned in the books and records of the
Associated Companies, including all of the properties and assets reflected in
the 1996 Balance Sheet (except for assets held under Material capitalized leases
disclosed or not required to be disclosed in Part 3.7 of the Disclosure Letter
and personal property sold since the date of the 1996 Balance Sheet, as the case
may be, in the Ordinary Course of Business), and all of the properties and
assets purchased or otherwise acquired by the Associated Companies since the

use restrictions, variances, reservations or limitations of any nature except,
with respect to all such properties and assets, (a) mortgages or security
interests shown on the Balance Sheet (and/or described in the notes thereto) as
securing specified liabilities or obligations, with respect to which no default
(or event that, with notice or lapse of time or both, would constitute a
default) exists, (b) mortgages or security interests incurred in connection with
the purchase of property or assets after the date of the Balance Sheet (such
mortgages and security interests being limited to the property or assets so
acquired), with respect to which no default (or event that, with notice or lapse
of time or both, would constitute a default) exists, (c) liens for current taxes
not yet due, and (d) with respect to real property, (i) minor imperfections of
title, if any, none of which is Material or impairs the use of the property
subject thereto, or impairs the operations of any Associated Company and (ii)
zoning laws and other land use restrictions that do not impair the present or
anticipated use of the property subject thereto. All buildings, plants and
structures owned by the Associated Companies lie wholly within the boundaries of
the real property owned by the Associated Companies and do not encroach upon the
property of, or otherwise conflict with the property rights of, any other
Person.

            3.8 Condition and Sufficiency of Assets. In all Material respects,

repair, subject to ordinary wear and tear, and are adequate for the uses to

<PAGE>   24
Companies as of the date set forth in Part 3.8 of the Disclosure Letter and all
equipment held under operating leases as of such dates are described in Part 3.8
of the Disclosure Letter. The building, plants, structures and equipment of the
Associated Companies are sufficient for the continued conduct of the Associated
Companies' businesses after the Closing in substantially the same manner and

Companies that are reflected on the 1996 Balance Sheet or on the accounting
records of the Associated Companies as of the Closing Date (collectively, the
"Accounts Receivable") represent or will represent valid obligations arising
from sales actually made or services actually performed in the Ordinary Course
of Business. Unless paid prior to the Closing Date, the Accounts Receivable are
or will be as of the Closing Date current and collectible net of the respective
reserves shown on the 1996 Balance Sheet or on the accounting records of the
Acquired Companies as of the Closing Date (which reserves are adequate and
calculated consistent with past practice and, in the case of the reserve as of
the Closing Date, will not represent a greater percentage of the Accounts
Receivable as of the Closing Date than the reserve reflected in the 1996 Balance
Sheet represented of the Accounts Receivable reflected therein and will not
represent a Material adverse change in the composition of such Accounts
Receivable in terms of aging). Except as noted in Part 3.9 of the Disclosure
Letter, subject to such reserves, each of the Accounts Receivable either has
been or will be collected in full, without any set-off, within ninety days after
the day on which it first becomes due and payable. Except as set forth in Part
3.9 of the Disclosure Schedule, there is no Material contest or claim other than
returns in the Ordinary Course of Business, under any Applicable Contract with
any maker of an Accounts Receivable relating to the amount or validity of, such
Accounts Receivable. Part 3.9 of the Disclosure Letter contains a complete and

                                       28
<PAGE>   38
            4.2  Authority; No Conflict.

                 (a) This Agreement constitutes the legal, valid and binding
obligation of Buyer, enforceable against Buyer in accordance with its terms.
Upon the execution and delivery by Buyer of this Agreement and the Rights
Agreement (collectively, the "Buyer's Closing Documents"), the Buyer's Closing
Documents will constitute the legal, valid, and binding obligations of Buyer,
enforceable against Buyer in accordance with their respective terms except as
such enforcement may be limited by applicable bankruptcy, insolvency,
reorganization, fraudulent conveyance, moratorium or other laws affecting
creditor's rights generally. Buyer has the absolute and unrestricted right,
power, and authority to execute and deliver this Agreement and the Rights
Agreement and to perform its obligations under this Agreement and the Rights
Agreement.

                 (b) Neither the execution and delivery of this Agreement by
Buyer nor the consummation or performance of any of the Contemplated
Transactions by Buyer will give any Person the right to prevent, delay, or
otherwise interfere with any of the Contemplated Transactions pursuant to:

                     (i)   any provision of Buyer's Organizational Documents;

                     (ii)  any resolution adopted by the board of directors or
the stockholders of Buyer;

                     (iii) any Legal Requirement or Order to which Buyer may be
subject; or

                     (iv)  any Contract to which Buyer is a party or by which
Buyer may be bound.

      Other than as required by the HSR Act with regard to the Tendered Shares
to be acquired at the Second Closing, Buyer is not and will not be required to
obtain any Consent from any Person in connection with the execution and delivery
of this Agreement or the consummation or performance of any of the Contemplated
Transactions.

             4.3 Investment Intent; Investigation.

                 (a) Buyer is familiar with the business and financial
condition, properties, operations and prospects of the Company. Buyer has been
given full access to all Material information concerning the condition,
properties, operations and prospects of the Company and its subsidiaries. Buyer
has had an opportunity to ask questions of, and to receive information from, the
Company and persons acting on its behalf concerning the terms and conditions of
Buyer's investment in the Shares, and to obtain any additional information
necessary to verify and accuracy of the


                                       29
<PAGE>   39
information and data received by Buyer. The Buyer has had an opportunity to
discuss with Company the financial statements delivered to the Buyer.

                 (b) Buyer has made such independent investigation of the
Company and its subsidiaries, its management, and related matters as the
undersigned deems to be necessary or advisable in connection with this
investment; and the undersigned has received all information and data which the
undersigned has requested from the Company and which Buyer believes to be
necessary in order to reach an informed decision as to the advisability of
investing in the Shares.

                 (c) Buyer understands that the purchase of the Shares involves
various risks, including those outlined in this Agreement. Among other risks,
Buyer understands that it is unlikely that any market will exist for any resale
of the Shares and that the Shares will be subject to restrictions on transfer as
set forth in the Company's Third Restated Articles of Incorporation.

                 (d) THE BUYER IS ACQUIRING THE SHARES SOLELY FOR ITS OWN
BENEFICIAL ACCOUNT, FOR INVESTMENT PURPOSES, AND NOT WITH A VIEW TO, OR FOR
RESALE IN CONNECTION WITH, ANY DISTRIBUTION OF THE SHARES. The Buyer
understands that the Shares have not been registered under the Securities Act,
or the securities laws of any state (collectively referred to as "State
Securities Laws") by reason of specific exemptions under the provisions thereof
which depend in part upon the investment intent of the undersigned and of the
other representations made by the undersigned in this Agreement. Buyer
understands that the Company is relying upon the representations and agreements
contained in this Agreement (and any supplemental information) for the purpose
of determining whether this transaction meets requirements for such exemptions.

                 (e) Buyer understands that the Shares are "restricted
securities" under the Securities Act and that the Securities Act and the rules
of the Securities and Exchange Commission (the "Commission") provide in
substance that the undersigned may dispose of the Shares only pursuant to an
effective registration statement under the Securities Act or an exemption
therefrom, and understands that the Company has no obligation or intention to
register any of the Shares thereunder, or to take action so as to permit sales
pursuant to the Securities Act. Accordingly, Buyer understands that under the
Commission's rules the undersigned may dispose of the Shares principally only in
"private placements" which are exempt from registration under the Securities
Act, in which event the transferee will acquire "restricted securities" subject
to the same limitations as in the hands of the undersigned. As a consequence,
Buyer understands that it must bear the economic risks of the investment in the
Shares for an indefinite period of time.

                 (f) Buyer is a corporation with total assets in excess of
$5,000,000.


                                       30
<PAGE>   40
             4.4 Certain Proceedings. There is no pending Proceeding that has
been commenced against Buyer and that challenges, or may have the effect of
preventing, delaying, making illegal, or otherwise interfering with, any of the
Contemplated Transactions. To the Buyer's Knowledge, no such Proceeding has been
threatened.

             4.5 Brokers or Finders. Buyer has incurred no obligation or
liability, contingent or otherwise, for brokerage or finders' fees or agents'
commission or other similar payment or connection with this Agreement.

             4.6 Consent. Buyer hereby consents to the Company granting stock
options, stock bonuses and similar rights to purchase shares of the common stock
of the Company in excess of the number of shares of common stock of the Company
which is equal to 30% of the outstanding shares of common stock of the Company.

        5.   Covenants of the Company Prior and Subsequent to First Closing
Date.

(c) furnish Buyer and Buyer's Advisors with copies of all such contracts, books

             5.2 Operation of the Business of the Company. Between the date of

to resolve the dispute amicably. If the parties cannot agree upon a resolution
within thirty days of either party requesting a meeting for resolution of a
dispute, then the matter will promptly be submitted to binding arbitration in
accordance with this Section 11.5.

                  (a) Arbitration will be held in Denver, Colorado, in
accordance with the rules and regulations of the American Arbitration
Association. The number of arbitrators will be one (1) for disputes less than
$200,000 and three (3) for all other disputes and will be selected in accordance
with the rules and regulations of the American Arbitration Association. The
determination of the arbitrator will be conclusive and binding upon the parties,
and any determination by the arbitrator of an award may be filed with the clerk
of a court of competent jurisdiction as a final adjudication of the claim
involved, or application may be made to such court for judicial acceptance of
the award and an order of enforcement, as the case may be. Except to the extent
otherwise directed by the arbitrator, each party will bear its own expenses,
including legal and accounting fees, if any, with respect to the


                                       40
<PAGE>   50
arbitration, and one-half of the costs of the arbitrator and of the fees imposed
by the American Arbitration Association.

                  (b) In any arbitration hereunder, the demand for arbitration
shall specifically delineate the claims asserted and the Material issues with
respect thereto. Within thirty days after filing a demand for arbitration,
claimant shall provide to respondent a list of all fact witnesses known to
claimants the names and curriculum vitae of each expert witness anticipated to
be called by claimant, and a copy of relevant documents. Within thirty days
after receipt of the foregoing information, respondent shall provide to claimant
a list of all fact witnesses known to respondent, the names and curriculum vitae
of each, expert witness anticipated to be called by respondent, and a copy of
relevant documents known to respondent. Within ten days after discovery has been
closed by the arbitrator (but in no event later than sixty days prior to the
arbitration hearing), claimant shall present to respondent a list of all fact
and expert witnesses anticipated to be called by claimant, a summary of the
substance of each such witness' testimony, and a list of all documents
anticipated to be introduced by claimant (and a copy of such documents if not
previously provided to respondent). Within thirty days after receipt of the
foregoing information, respondent shall present to claimant a list of all fact
and expert witnesses anticipated to be called by respondent, a summary of the
substance of each such witness' testimony and a list of all documents
anticipated to be introduced by respondent (and a copy of such documents if not
previously provided to claimant). Any award by the arbitrator shall be subject
to all dollar and other limitations set forth in this Agreement.

                  (c) A demand for arbitration may be served on Buyer or the

intent of this Agreement and the documents referred to in this Agreement.

Agreement are cumulative and not alternative. Neither the failure nor any delay
by any party in exercising any right, power or privilege under this Agreement or
the documents referred to in this Agreement will operate as a waiver of such
right, power, or privilege, and no single or partial exercise of any such right,
power, or privilege will preclude any other or further exercise of such right,
power, or privilege or the exercise of any other right, power, or privilege. To
the maximum extent permitted by applicable law, (a) no claim or right arising
out of this Agreement or the documents referred to in this Agreement can be
discharged by one party, in whole or in part, by a waiver or renunciation of the
claim or right unless in writing signed by the other party; (b) no waiver that
may be given by a party will be applicable except


                                       41
<PAGE>   51
in the specific instance for which it is given and (c) no notice to or demand on
one party will be deemed to be a waiver of any obligation of such party or of
the right of the party giving such notice or demand to take further action
without notice or demand as provided in this Agreement or the documents referred
to in this Agreement.

             11.8 Indemnification. To the fullest extent permitted by law, the
Company shall indemnify, defend with counsel reasonably satisfactory to Buyer
and hold harmless Buyer, its officers, directors, employees and agents (each an
"Indemnified Party"), from and against (i) any and all claims, demands, causes

                        COOPERATION AND RIGHTS AGREEMENT

      This Cooperation and Rights Agreement (this "Agreement") is entered into
as of December 23, 1996 (the "Effective Date"), by and among Granite
Construction Incorporated, a Delaware corporation ("Granite"), TIC Holdings,
Inc., a Colorado corporation (the "Company") and the shareholders of the Company
listed on Exhibit A hereto (the "Holders"). Unless otherwise indicated,
capitalized terms have the meanings ascribed to them in that certain Stock
Purchase Agreement of even date herewith between Granite and the Company (the
"Purchase Agreement"). Granite, the Company and the Holders are collectively
referred to herein as the "Parties".

                                    RECITALS

      A. As of September 30, 1996 the Company had authorized 5,000,000 shares of
stock, of which 2,000,000 shares have been classified as Preferred Stock, none
of which are outstanding, 2,500,000 shares have been classified as Class A
Common Stock, of which 771,379 shares were outstanding as of September 30, 1996,
and 500,000 shares have been classified as Class B Common Stock, none of which
are outstanding. Immediately prior to the First Closing under the Purchase
Agreement, the Holders hold 291,133 shares of the Company's outstanding Class A
Common Stock. Class A common stock, Class B common stock, Preferred Stock and
all other classes of stock authorized and issued by the Company (consistent with
Section 5 of this Agreement) (all section references are to the sections of this
Cooperation and Rights Agreement, unless otherwise indicated) are collectively
referred to herein as "Stock".

      B. Granite is purchasing from the Company and from shareholders of the
Company 257,126 shares of the Company's Class A Common Stock ("Granite Shares")
pursuant to the Purchase Agreement.

      C. The Company, the Holders and Granite desire to set forth certain rights
and obligations of the Parties as set forth herein.

                                    AGREEMENT

      NOW, THEREFORE, in consideration of the foregoing and of the mutual
promises and covenants contained herein, the parties agree as follows:

      1.    Right of Maintenance; Right to Acquire 51%; Standstill.

            1.1 The Right to Purchase Adjustment Stock and Majority Stock. The
Company hereby grants to Granite the right to purchase from the Company all or
any part of the Adjustment Stock (as defined in Section 1.2), if any, within
thirty (30) days after October 31 of each year during the five years after the
Effective Date and in addition, the right to purchase from the Company the
Majority Stock (as defined in Section 1.2) within the one month period
commencing on the sixth anniversary of the Effective Date, provided that neither
the Company nor Granite has exercised their rights pursuant to Sections 6.1 or


                                        1
<PAGE>   55
6.2 of this Agreement (or given notice of their intent to exercise such rights)
as of the date of any purchase of Adjustment Stock or Majority Stock. The
purchase price per share for each share of Adjustment Stock and Majority Stock
shall equal the Designated Purchase Price (as defined in Article VI.A. of the
Company's Third Restated Articles of Incorporation (the "Restated Articles"))
used to transfer shares under Article VI of the Restated Articles as of the date
of each respective purchase of Adjustment Stock or Majority Stock by Granite
hereunder and shall be paid to the Company by wire transfer on or before the
applicable date that Granite's right to purchase such shares under this Section
1.1 expires, if and to the extent Granite elects to purchase such shares.

            1.2 Adjustment Stock and Majority Stock. "Adjustment Stock" shall
mean that number of shares of the Company's Class A Common Stock (rounded to the
nearest whole share) which, when issued and sold to Granite, will result in
Granite owning 30% of the total number of outstanding shares of the Company's
Stock entitled to vote ("Voting Stock") immediately after Granite purchases such
Voting Stock based upon the Voting Stock outstanding as of October 31 of such
year. "Majority Stock" shall mean that number of shares of the Company's Class A
Common Stock (rounded to the nearest whole share) which, when issued and sold to
Granite, will result in Granite owning 51% of the Voting Stock immediately after
Granite purchases such Voting Stock based upon the Voting Stock outstanding as
of October 31, 2002.

            1.3 Notice. Between October 31 and November 10 of each year,
beginning in the year after the Effective Date, the Company shall provide
Granite with written notice as to the number of shares of Adjustment Stock or
Majority Stock, as the case may be, that may be purchased by Granite in such
year, together with the basis for such calculation and the then effective
Designated Purchase Price.

            1.4 Standstill. Notwithstanding any other provision herein to the
contrary, other than upon the exercise of its rights pursuant to Section 2
below, pursuant to Section VI.C.2 of the Restated Articles or upon receipt of
the prior written consent of the Company, Granite agrees not to acquire more
than 49.9% of the Voting Stock of the Company that is issued and outstanding
during the five year period commencing on the Effective Date.

            1.5 Contingent Waiver of Rights. The Parties do not intend to
qualify as a "Controlled Group of Corporations" under Section 1563 of the
Internal Revenue Code of 1986, as amended (the "Code"). In furtherance of this
stated intent:

                (a) Company Waiver. The Company hereby waives its rights under
Article VI of the Restated Articles to purchase the Stock held by the
shareholders of the Company listed on Exhibit B attached hereto (the "Waiver
Shareholders"), if and to the extent such waiver is necessary to avoid Granite
and the Company Qualifying as a "Controlled Group of Corporations" under Section
1563 of the Code. This waiver shall be irrevocable as to each Waiver Shareholder
without the prior written consent of such Waiver Shareholder and Granite.


                                        2
<PAGE>   56
                (b) Granite Waiver. Granite hereby waives its rights, if any,
under Article VI of the Restated Articles to purchase the Stock from the Waiver
Shareholders, if and to the extent such waiver is necessary to avoid Granite and
the Company qualifying as a "Controlled Group of Corporations" under Section
1563 of the Code. This waiver shall be irrevocable as to each Waiver Shareholder
without the prior written consent of such Waiver Shareholder and the Company.

                (c) To the extent the waivers described in Sections 1.5(a) and
1.5(b), above, are collectively insufficient to avoid Granite and the Company
qualifying as a Controlled Group of Corporations, the Company hereby waives its
rights under Article VI of the Restated Articles and Granite hereby waives its
rights, if any, under Article VI of the Restated Articles to purchase Stock from
any of the Shareholders of the Company who are also employees of the Company,
other than the Waiver Shareholders (the "Employee Shareholders"), as specified
hereafter. The maximum number of shares of Stock to which this waiver applies
shall be the minimum number of shares of Stock held by Employee Shareholders as
may be necessary to avoid Granite and the Company qualifying as a Controlled
Group of Corporations under Section 1563 of the Code. The number of shares of
Stock held by any Employee Shareholder which is subject to the waiver shall be
the total number of shares of Stock held by such Employee Shareholder multiplied
by a fraction, the numerator of which is the total number of shares of Stock
subject to this waiver and the denominator of which is the total number of
shares of Stock owned by the Employee Shareholders. This waiver provided in this
Section 1.5(c) shall apply only in the event that the waivers described in
Sections 1.5(a) and 1.5(b), above, are collectively insufficient to avoid
Granite and the Company qualifying as a Controlled Group of Corporations and, in
such event, this waiver shall be in addition to the waivers set forth in Section
1.5(a) and 1.5(b), above. The waiver contained in this Section 1.5(c) shall be
irrevocable.

                (d) The provisions of this Section 1.5 shall be interpreted in
such a manner as to be consistent with the objective of Granite and the Company
not qualifying as a Controlled Group within the meaning of Section 1563 of the
Code.

            1.6 Company Undertaking. At all times that Granite holds less than
51% of the issued and outstanding shares of the voting stock of the Company, the
Company agrees that it shall not, without Granite's prior written consent,
redeem or repurchase shares of its voting stock, if upon the completion of such
redemption or repurchase Granite would own or be considered to own for purposes
of Code Section 1563, eighty percent (80%) or more of the Company's voting
stock.

      2.    Right of First Offer in the Event of a Proposed Sale to Third
Parties.

            (a) For as long as (i) Granite holds at least fifteen percent (15%)
of the Voting Stock of the Company, but less than 75% of the Voting Stock of the
Company and (ii) neither the Company nor Granite has exercised their rights
pursuant to Sections 6.1 or 6.2 of this Agreement (or given notice of their
intent to exercise such rights), the Company hereby grants to Granite, subject
to Section 2(b)(i)(B) below, the right to purchase: (A) any


                                       3
<PAGE>   57
Stock or any securities evidencing an ownership interest in the Company, or any
securities convertible into, exchangeable for or exercisable for Stock or any
securities issuable pursuant to any agreement or commitment to issue Stock (the
"Securities") or (B) the assets ("Assets") offered for sale in connection with
the sale of all or substantially all of the assets of the Company, which
Securities or Assets the Company may, from time to time, propose to issue or
sell to persons or entities other than Granite ("Third Parties"), whether in an
effort to raise capital through the issuance of new Securities or pursuant to a
sale of the Company by reason of merger, reorganization to avoid bankruptcy,
acquisition or asset sale. If Granite exercises the right to purchase described
herein, the purchase price and all other transaction terms shall be equivalent
to those proposed to be offered to the Third Parties.

            (b) Procedure.

                (i)  Each time the Company proposes to offer Securities or
Assets to a Third Party, the Company shall first make an offering of such
Securities or Assets to Granite in accordance with the following provisions:

                     (A) The Company shall deliver a notice ("Notice") to
Granite stating (i) its bona fide intention to offer such Securities or Assets
to a Third Party, (ii) the description of Securities or Assets to be offered and
(iii) the price and terms, if any, upon which it proposes to offer such
Securities or Assets.

                     (B) Within 20 calendar days after receipt of the Notice,
Granite may elect to purchase or obtain, at the price and on the terms specified
in the Notice, all of the Securities or Assets offered by delivery of written
notice of such election to the Company, provided however, that if the proposed
sale is of Securities for purposes of raising capital for the Company, Granite
may elect to purchase either (i) all of such Securities, or (ii) up to 30% of
such Securities if the Third Parties continue to be willing to purchase the
remainder of the offering.

                (ii) If Granite does not timely elect to purchase all of the
Securities or Assets which Granite is entitled to obtain pursuant to Section
2(b)(i) above, the Company may, during the 180-day period following the
expiration of the period provided in subsection (i) hereof, offer the remaining
unsubscribed portion of such Securities or Assets to any person or persons at a
price not less than, and upon terms no more favorable to the offeree than, those
specified in the Notice. If the Company does not enter into an agreement for the
sale of the Securities or Assets within such 180 day period, or if such
agreement is not consummated within 90 days of the execution thereof, the right
provided hereunder shall be deemed to be revived and such Securities or Assets
shall not be offered unless first re-offered to Granite in accordance with the
terms of this Section 2.

            (c) Granite Transferees. In addition to any limitations or
restrictions contained in the Restated Articles, any person or entity acquiring
Stock from or through Granite will be subject to all the obligations,
restrictions, limitations and other duties of Granite contained in this
Agreement. No transfer of any Stock held by Granite shall serve


                                        4
<PAGE>   58
to terminate, cancel, alter, amend, diminish or otherwise affect the rights of
the Company, the Holders or the shareholders of the Company other than Granite
(the "Non-Granite Shareholders") referenced in this Agreement.

            (d) Stock Rights of Holders. No part of this Agreement (including,
but not limited to this Section 2) shall preclude the Company from issuing stock
options or stock bonuses and/or from selling Stock to its employees (and the
employees of the Associated Companies) subject to approval by the Board of
Directors and consistent with the past practices of the Company and any such
issuance shall not be subject to Granite's Right of First Offer set forth in
this Section 2.

      3.    Voting Rights.

            3.1 Election of Members of the Board of Directors. Provided neither
the Company nor Granite has exercised their rights (or given notice of their
intent to exercise their rights) pursuant to Section 6.1 or 6.2 of this
Agreement, with respect to any proposal concerning the election of directors of
the Company, the Parties agree as follows:

                (a) Representatives of Granite. At all times following Granite's
purchase of the Granite Shares in accordance with the Purchase Agreement, the
Company and the Holders agree to cause to be nominated, and each of the Holders
agrees to vote all shares of the Company's Voting Stock then owned by such
Holder to elect the nominees of Granite to the Board of Directors of the
Company; provided, however, that the Company and the Holders shall not be
required to nominate and no Holder shall be required to vote such Holder's
shares for more than that number of Granite designees equal to the total number
of directors then authorized and serving multiplied by the percentage of shares
of Voting Stock of the Company then held by Granite or its affiliates, rounded
to the nearest whole number. Granite designates David H. Watts, William E.
Barton, William G. Dorey and Patrick H. Costanzo as its initial designees and
the Holders and the Company shall cause such persons to be elected by the
current Board of Directors effective upon the First Closing of Granite's
purchase of the Granite Shares in accordance with the terms of the Purchase
Agreement.

                (b) Non-Granite Representatives. At all times following
Granite's purchase of the Granite Shares in accordance with the Purchase
Agreement, Granite agrees to vote all shares of the Company's Voting Stock then
owned by Granite to elect the nominees designated by a majority of the members
of the Board not previously designated or nominated by Granite ("Non-Granite
Board Members") and if such Non-Granite Board Members fail to so designate, the
nominees designated by a majority of the Non-Granite Shareholders; provided,
however, that Granite shall not be required to vote its shares for more than
that number of Non-Granite designees equal to the total number of directors then
authorized and serving multiplied by the percentage of shares of Voting Stock of
the Company then held by Non-Granite Shareholders, rounded to the nearest whole
number.

                (c) Authorized Number of Directors. The authorized number of
directors shall be determined in accordance with the Bylaws of the Company.
Granite


                                        5
<PAGE>   59
agrees to vote all of its votes on the Board with the majority decision of the
Non-Granite Board Members in all proposed actions to fix or modify the
authorized number of members of the Board.

      4.    Approval of Certain Changes.

            (a) The Company covenants and agrees that it shall not, without the
approval of a majority of the Board, including at least one director designated
by Granite and elected as set forth in Section 3 above, take any of the
following actions:

                (i)    Change the salary structure, incentive compensation
plans, or other compensation programs that would have the effect of
significantly increasing the Company's salaried employee compensation levels as
a percentage of the Company's total revenue or as a percentage of the Company's
total profits.

                (ii)   Except to the extent of those dividends necessary to
maintain the Cross Purchase Insurance Trust (the "Trust") (i.e. the PS-58
dividend) and an equivalent dividend to those shareholders, including Granite,
that do not participate in the Trust, declare any dividend to the Company's
shareholders that would negatively impact the share of profits or equity
increase that would otherwise accrue to Granite or declare any dividend in
excess of fifteen percent (15%) of after-tax profits not in accordance with past
practice of the Company.

                (iii)  Change the Company's capital structure in a manner that
would disproportionately impact Granite's participation in profits or equity.

                (iv)   Conclude an initial public offering of the Company.

                (v)    File for voluntary bankruptcy or a dissolution of the
Company.

                (vi)   Enter any extraordinary borrowing arrangements
inconsistent with past practice of the Company.

                (vii)  Approve an acquisition by the Company of any entity:

                      (A) Competitive with Granite;

                      (B) At a purchase price in excess of ten percent (10%) of
stockholders' equity as shown on the Company's most recent financial statements;
or

                      (C) Outside the Company's traditional line of business.

                (viii) Excluding contractual joint ventures, consortiums or
other similar arrangements in which the Company (or any of its subsidiaries) is
or may become a party, acquire equity interests in projects or minority
interests in other companies in


                                        6
<PAGE>   60
excess of twenty percent (20%) of the Company's total stockholders' equity when
such acquisition or investment is cumulated with other similar investments.

                (ix) Excluding the issuance of stock options or stock bonuses
consistent with the past practices of the Company, authorize and issue any new
classes of stock of the Company.

                (x)  Enter into a transaction that would cause it to fail to
maintain the following ratios: (A) Consolidated liabilities less permitted
subordinated debt to consolidated tangible equity plus permitted subordinated
debt in a ratio of no more than two to one; and (B) cash flow coverage ratio
defined as net income plus depreciation and amortization divided by current
maturities of long term debt in a ratio of no less than 1.75 to one.

            (b) The foregoing provisions notwithstanding, any and/or all of the
foregoing actions may be taken by the Company without the approval of any Board
member designated by Granite where such actions are taken pursuant to the
exercise of the Company's rights provided in Section 6.1 or to fulfill the
Company's obligations pursuant to the exercise of Granite's rights provided in
Section 6.2.

      5.    Understandings Regarding Granite's Role in TIC.

            5.1 The Parties acknowledge that Granite's acquiring the Granite
Shares is a possible first step toward establishing a long term relationship
with the Company for the strategic and financial benefit of shareholders of both
Granite and the Company. This Agreement has been structured to enable Granite
and the Company to avoid making irrevocable long term commitments until
officers, employees and directors of each company have had a three year
opportunity to decide whether such a closer long term relationship is in their
mutual interest.

            5.2 At all times that Granite is a shareholder of the Company,
Granite and the Directors of the Company who Granite designates shall be mindful
of the best interests of the Non-Granite Shareholders, of the Company's
corporate culture and Core Values and of the Company's history and reputation in
its marketplace.

            5.3 In the event Granite does acquire fifty-one percent (51%) or
more of the Voting Stock, Granite will exercise its fiduciary duty to protect
the rights of the Non-Granite Shareholders in accordance with applicable law and
consistent with this Agreement. Specifically, and without limitation of the
foregoing, Granite will maintain equity incentive plans generally consistent
with the past practices of the Company and a Stock repurchase policy for
employees and shareholders of the Company and the Associated Companies. Such
Stock repurchase policy will include a mechanism for the sale of such Stock into
the public market, to Granite and/or to the Company. Such programs shall be
maintained by the Board and/or the Board of Granite and shall provide for the
repurchase of Stock by the Company and/or Granite consistent with the past
practice of the Company as to eligibility. Such repurchases of Stock shall be
made, to the


                                        7
<PAGE>   61
extent of shareholders desiring to sell, in an amount at least equal to one
hundred and twenty percent (120%) of the average level of funds available for
repurchases using the formula established by the Company's bank covenants for
fiscal year 1997 as specified in the Second Amendment to First Amended and
Restated Loan Agreement by and among TIC Holdings, Inc. and its subsidiaries,
Norwest Bank Colorado, National Association, Bank One, Arizona, N.A. and Harris
Trust and Savings Bank dated July 1, 1996 for the six (6) year period prior to
the time Granite becomes entitled to acquire the Majority Stock, provided either
Granite or the Company have the financial ability to make such repurchases on
the repurchase date.

      6.    Repurchase of Granite's Shares by the Company.

            6.1 The Company's Call Right.

                (a) The Right. The Company shall have the right, upon providing
thirty (30) days prior written notice to Granite, to repurchase all or any part
of the Granite Shares and any or all other shares of the Company then held by
Granite, upon any of the following events or dates:

                    (i)   any proposed transfer of all or any part of the
Granite Shares and other shares of the Company then held by Granite to a third
party, excluding for such purposes transfers by Granite to Granite Construction
Company ("Granite Company");

                    (ii)  the closing of any merger or consolidation or exchange
of stock of Granite and/or Granite Company, if the Granite Shares or any other
shares of the Company have been transferred to Granite Company, with any other
corporation or entity after which any party or group of related parties acquires
more than 50% of the voting stock of the resulting entity.

                    (iii) the acquisition of the majority of the issued and
outstanding voting stock of Granite and/or Granite Company, if the Granite
Shares or any other shares of the Company have been transferred to Granite
Company, by a person or entity not a Granite shareholder as of the Effective
Date;

                    (iv)  Granite's total stockholder's equity, as indicated in
any public annual or quarterly financial statement of Granite, is less than
$50,000,000; or

                    (v)   during the one month period commencing three years
after the Effective Date.

                (b) Amount and Delivery of Repurchase Price. The price per share
and payment terms for any purchase pursuant to this Section 6.1 shall be
determined as follows:


                                        8
<PAGE>   62
                    (i)   For repurchases described in Section 6.1(a)(i), the
purchase price per share and terms shall be the price per share and proposed
terms of the proposed transfer. Each time that Granite proposes to offer Stock
to a party that is not a shareholder of the Company ("Granite Offeree"), Granite
shall first deliver a notice ("Notice") to the Company stating (i) its bona fide
intention to offer such Stock to a Granite Offeree and the name of the Granite
Offeree, (ii) the description of Stock to be offered and (iii) the price and
terms, if any, upon which it proposes to offer such Stock. Within 20 calendar
days after receipt of the Notice, the Company may exercise its rights under
Section 6.1(a), at the price and on the terms specified in the Notice. If the
Company does not timely elect to obtain all of the Stock which Granite proposes
to sell within the 20 day period specified herein, Granite may, during the
180-day period following the expiration of the 20 day period, offer the Stock to
the person or persons specified in Granite's Notice at a price not less than,
and upon terms no more favorable to the Granite Offeree than, those specified in
the Notice. If Granite does not enter into an agreement for the sale of the
Stock consistent with its Notice within such 180 day period or if such agreement
is not consummated within 90 days of the execution thereof, the Company's right
hereunder shall be deemed to be revived and such Stock shall not be offered to a
third party unless first re-offered to the Company in accordance with the terms
of this Section 6.

                    (ii)  For repurchases described in Section 6.1(a)(ii), (iii)
or (iv) and in Section 6.2, the purchase price per share shall be equal to the
Designated Purchase Price (as defined in Article VI.A. of the Restated Articles)
as of the date of notice of the repurchase. Granite shall give the Company
written notice of the occurrence of any of the events described in Section
6.1(a)(ii), (iii) or (iv) within 20 business days of the happening of such
event. Payment of the purchase price to Granite shall be made by five year
promissory note secured by the assets of the Company (subject to all then
existing security interests and bonding obligations of the Company and execution
of any normal and customary subordination agreements required by the Company's
primary lender) bearing interest at the 60 day reference rate charged by Bank of
America NT&SA providing for five annual installments of principal with accrued
interest, with the first installment due one year following the date of notice
of repurchase.

                    (iii) For repurchases described in Section 6.1(a)(v), the
purchase price per share shall be equal to the greater of: (A) the purchase
price determined according to Section 6.1(b)(ii); or (B) the original
acquisition price per share paid by Granite for the Granite Shares plus
interest, compounded annually, from the date the shares were paid for by Granite
calculated at one percent (1%) above the 60-day reference rate charged by Bank
of America NT&SA. The purchase price shall be payable at any time as the Company
shall elect prior to the second anniversary of the date of notice delivered
pursuant to Section 6.1(a)(v).

            6.2 Granite's Put Right. Granite shall have the option to cause the
Company to repurchase all or any part of the Granite Shares and other shares of
the Company then held by Granite by giving written notice to the Company during
the one week period commencing three years after the Effective Date. The
purchase price shall be calculated and paid as set forth in Section 6.1(b)(ii).

acquisition of any industrial construction firm and to seek a cooperative method
of making any such acquisition.

            7.2 Certain Limitations. At all times consistent with Section 5 of
this Agreement, Granite's involvement with the Company shall be limited to

patterns of profitability and viability. In addition, the Company shall maintain
its identity and the integrity of its systems and financial structure so long as
it is able to maintain historical patterns of profitability and viability.
Notwithstanding the foregoing, it is specifically agreed and understood that
neither the foregoing language nor any other provision of this Agreement shall

Directors from exercising its best business judgment, normal corporate rights
and/or the statutory duties of corporate governance.

      8.    Stock Legends. (a) All certificates representing shares of capital

COOPERATION AND RIGHTS AGREEMENT AMONG THE CORPORATION, THE HOLDER HEREOF AND

                (ii) THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT
BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT") OR
REGISTERED OR QUALIFIED UNDER ANY APPLICABLE STATE SECURITIES LAWS AND ARE
"RESTRICTED SECURITIES" AS DEFINED IN RULE 144 PROMULGATED UNDER THE ACT. THE

      9.    Miscellaneous.

            9.1 Notices. All notices, consents, waivers, and other
communications under this Agreement must be in writing and will be deemed to
have been duly given when (a) delivered by hand (with written confirmation of
receipt), (b) sent by facsimile (with written confirmation of receipt), provided
that a copy is mailed within three business days by registered mail, return
receipt requested, (c) when received by the addressee, if sent by a nationally
recognized overnight delivery service (receipt requested) or (d) three business
days after being sent by registered or certified mail, return receipt requested,
in each case to the appropriate addresses and facsimile numbers set forth under
the signature of the party (or to such other addresses and facsimile numbers as
a party may designate by notice to the other parties).

            9.2 Binding Arbitration. In the event of a dispute between the
Parties related to or arising out of this Agreement, representatives of the
Parties will meet promptly in an effort to resolve the dispute amicably. If the
Parties cannot agree upon a resolution within thirty days of either Party
requesting a meeting for resolution of a dispute, then the matter will promptly
be submitted to binding arbitration in accordance with the arbitration
provisions contained in the Purchase Agreement.

            9.3 Further Assurances. The Parties agree (a) to furnish upon
request to each other such further information, (b) to execute and deliver to
each other such other documents and (c) to do such other acts and things, all as
the other Party may reasonably request for the purpose of carrying out the
intent of this Agreement and the documents referred to in this Agreement.

            9.4 Waiver. The rights and remedies of the Parties hereunder are
cumulative and not alternative. Neither the failure nor any delay by any Party
in exercising any right, power or privilege under this Agreement or the
documents referred to in this Agreement will operate as a waiver of such right,
power, or privilege, and no single or partial exercise of any such right, power,
or privilege will preclude any other or further exercise of such right, power,
or privilege or the exercise of any other right, power, or privilege. To the
maximum extent permitted by applicable law, (a) no claim or right arising out of
this Agreement or the documents referred to in this Agreement can be discharged
by one Party, in whole or in part, by a waiver or renunciation of the claim or
right unless in writing signed by the other Party; (b) no waiver that may be
given by a Party will be applicable except in the specific instance for which it
is given and (c) no notice to or demand on one Party will be deemed to be a
waiver of any obligation of such Party or of the right of the Party giving such
notice or demand to take further action without notice or demand as provided in
this Agreement or the documents referred to in this Agreement.

            9.5 Entire Agreement and Modification. This Agreement supersedes all
prior agreements between the Parties with respect to its subject matter
(including the Draft Summary of Terms of Proposed Investment by Granite
Construction, Inc. ("Granite") in TIC Holdings, Inc. ("TIC")) and constitutes a
complete and exclusive statement of the terms


                                       12
<PAGE>   66
of the agreement between the Parties with respect to its subject matter. This
Agreement may not be amended except by a written agreement executed by Granite
and the Company, unless such change affects the Holders, in which case it must
also be executed by Holders holding a majority of the shares of Voting Stock of
the Company then held by the Holders as a group.

            9.6  Assignments, Successors and No Third Party Rights. Neither
Party may assign any of its rights under this Agreement without the prior
consent of the other Party, which will not be unreasonably withheld if such
rights are of a purely financial nature without strategic implications except
that Granite may assign any of its rights under this Agreement to Granite
Construction Company, but Granite will not be relieved of its obligations
hereunder as a result of such assignment. Subject to the preceding sentence,
this Agreement will apply to, be binding in all respects upon, and inure to the
benefit of the successors and permitted assigns of the Parties. Nothing
expressed or referred to in this Agreement will be construed to give any person
other than the Parties (and with regard to Sections 5 and 7, shareholders of the
Company) any legal or equitable right, remedy or claim under or with respect to
this Agreement or any provision of this Agreement. This Agreement and all of its
provisions and conditions are for the sole and exclusive benefit of the Parties
to this Agreement (and with regard to Sections 5 and 7, shareholders of the
Company) and their successors and assigns.

            9.7  Severability. If any provision of this Agreement is held
invalid or unenforceable by any court of competent jurisdiction, the other
provisions of this Agreement will remain in full force and effect. Any provision
of this Agreement held invalid or unenforceable only in part or degree will
remain in full force and effect to the extent not held invalid or unenforceable.

            9.8  Time of Essence. With regard to all dates and time periods set
forth or referred to in this Agreement, time is of the essence.

            9.9  Governing Law. This Agreement will be governed by and construed
under the laws of the State of Colorado without regard to conflicts of laws
principles.

            9.10 Counterparts. This Agreement may be executed in one or more
counterparts, each of which will be deemed to be an original copy of this
Agreement and all of which, when taken together, will be deemed to constitute
one and the same agreement.


                                       13

                              Officer's Certificate


      The undersigned officer of TIC Holdings, Inc., a Colorado corporation
("TIC")(1), in connection with the rendering by Gray Cary Ware & Freidenrich
("GCWF") of the opinion with respect to the Stock Purchase Agreement and the
Cooperation and Rights Agreement (the "Rights Agreement") by and between Granite
Construction Incorporated, a Delaware corporation ("Granite"), and TIC, and
recognizing that GCWF will rely on this Certificate in rendering such opinion,
hereby certifies as follows:

      1. On September 30, 1996, a total of 771,379 shares of Class A Common
Stock of TIC Holdings, Inc. ("Common Stock") was outstanding. This number of
outstanding shares of Common Stock does not include any shares of Common Stock
held as Treasury Stock by TIC, nor does this number include any authorized but
unissued shares of Preferred Stock and/or Class B Common Stock.

      2. No voting rights are associated with shares of Class B Common Stock,
and the voting rights of Preferred Stock are to be determined by the Board of
Directors of TIC (the "Board") upon the issuance of any shares of Preferred
Stock. As of the Effective Date of the Rights Agreement and immediately prior
thereto, there are no outstanding shares of Class B Common Stock or Preferred
Stock.

      3. On September 30, 1996, the 771,379 shares of outstanding Common Stock

                               December 30, 1996



To TIC Holdings, Inc.,
a Colorado corporation:

      We are legal counsel to Granite Construction Incorporated, a Delaware
corporation (the "Buyer") and we are rendering this opinion pursuant to Section
8.4 of the Stock Purchase Agreement dated December 23, 1996 between the TIC
Holdings. Inc., a Colorado corporation (the "Company") and Buyer (the "Stock
Purchase Agreement") and the Cooperation and Rights Agreement dated December 23,
1996 between the Company, Buyer and certain shareholders of the Company (the
"Rights Agreement") in connection with the purchase by Buyer of up to 257,126
shares of the Company's Class A Common Stock (the "Shares"). Capitalized terms
used in this opinion, unless specifically defined herein, have the meanings
assigned them in the Stock Purchase Agreement. The Stock Purchase Agreement and
the Rights Agreement may collectively be referenced to herein as the
"Agreements."

      In connection with this opinion, we have reviewed only the documents of
Buyer listed on Exhibit A hereto. As to factual matters, we have relied solely
upon, and assumed the accuracy, completeness, and genuineness of, a certificate
of an officer of the Buyer (the "Certificate"), certificates of public officials
and oral and written representations made to us by officers of Buyer. We have
made no independent investigation of any of the facts stated in any such
certificate or representation; however, nothing has come to our attention which
would lead us to believe that such facts are inaccurate. With respect to our
opinion in Paragraph 3 hereof regarding material agreements of Buyer, we have
relied solely upon our review of agreements filed as exhibits to Buyer's filings
with the Securities and Exchange Commission ("SEC"). With respect to our opinion
in Paragraph 3 regarding judgments, decrees and orders, we have relied solely
upon a representation made to us in the Certificate to the effect that except as
may otherwise be set forth in the Agreements and the Exhibits thereto, there are
no judgments, decrees or orders binding upon Buyer. We are not aware of any
judgment, decree or order binding upon Buyer.

      In those instances in which our opinion is "to our knowledge," it is based
solely upon an inquiry of attorneys within our firm who perform legal services
for the Company, review of the Certificate and such additional review as is
specified above.

      In addition, we have assumed that the representations and warranties as to
factual matters made by the Company and Buyer in Sections 3 and 4, respectively,
of the Stock
<PAGE>   77
Page 2



Purchase Agreement are true and correct. We have also assumed the genuineness
and authenticity of all documents submitted to us as originals, the conformity
to originals of all documents submitted to us as copies, the due execution and
delivery of the Agreements and all other documents referenced therein by any
party other than the Buyer when due execution and delivery are a prerequisite to
the effectiveness thereof, that you have received all of the documents that you
were required to receive under the Agreements, and that the Agreements and all
other documents referenced therein are binding obligations of the Company.

      We are admitted to practice law only in the State of California, and we
express no opinion concerning any law other than the law of the State of
California, the corporation laws of the State of Delaware ("Delaware Law") and
the federal law of the United States. As to matters of Delaware Law, we have
based our opinion solely upon our examination of such laws and the rules and
regulations of the authorities administering such laws, all as reported in
standard, unofficial compilations. Opinions of counsel licensed to practice law
in states or jurisdictions other than the State of California have not been
obtained. We call your attention to the fact that the Agreements state that they
are governed by the laws of the State of Colorado and that we are not rendering
any opinion with respect to Colorado laws. We have not examined the question of
what law would govern the interpretation or enforcement of the Agreements and
our opinion is based on the assumption that the internal laws of the State of
California and federal law would govern the provisions of the Agreements and the
transactions contemplated thereby. We note that if the Agreements are not, in
fact, legal, valid, binding and enforceable under the laws of the State of
Colorado, the Agreements may not be enforced by a California court under
applicable conflicts of law principles. We express no opinion with respect to
any questions of choice of law, choice of venue or conflict of laws.

      We express no opinion with respect to (i) the availability of equitable
remedies, including specific performance, (ii) the enforceability of the
Agreement under Section 1670.5 of the California Civil Code.

      Subject to the foregoing, it is our opinion that as of the date hereof.

      1. The Buyer is a corporation duly organized, validly existing and in good
standing under the laws of the State of Delaware. The Buyer has all requisite
corporate power to own and operate its properties and assets, and to carry on
its business as presently conducted.

      2. The Company has all requisite corporate power to enter into the
Agreements, to purchase the Shares and the Tendered Shares, and to carry out and
perform its obligations under the terms thereof. The Agreements have been duly
authorized by all necessary corporate action on the part of Buyer and have been
duly executed and delivered by Buyer. The Agreements are valid and binding
obligations of Buyer, enforceable in accordance with their terms, except as
limited by applicable
<PAGE>   78
Page 3



bankruptcy, insolvency, reorganization, moratorium or other laws of general
application affecting the enforcement of creditors' rights.

      3. The execution, delivery or performance of the Agreements will not
violate any term of Buyer's Certificate of Incorporation or By-Laws; and, to our
knowledge, such transactions will not, in any material respect, violate or
conflict with or constitute a default under the provisions of any material
agreement, judgment, decree or order binding upon the Buyer.

      4. To our knowledge, except as described or disclosed in the Agreements or
in exhibits thereto, no action, suit, proceeding or investigation is pending or
threatened against Buyer or its properties, which would prevent Buyer from
carrying out its obligations under the Agreements.

      5. As of the date of the First Closing, all consents, approvals and
authorizations of and filings with any federal or California governmental
authority required on the part of Buyer, if any, in connection with the valid
execution and delivery of the Agreements or the consummation of the transactions
contemplated thereby have been obtained or made, except filings to be made under
the HSR Act which filing is required prior to the Second Closing.

      The foregoing opinion is intended solely for your benefit and is not to be
made available to or be relied upon by any other person, firm, or entity without
our express prior written consent.


                                                Very truly yours,

Granite Construction Incorporated
585 West Beach Street
Watsonville, CA 95076

Ladies and Gentlemen:

      This opinion is provided in connection with the Stock Purchase Agreement
between Granite Construction Incorporated, a Delaware corporation ("Granite")
and TIC Holdings, Inc., a Colorado corporation ("TIC") and in connection with
the Cooperation and Rights Agreement (the "Rights Agreement") between Granite
and TIC.

      Pursuant to the Stock Purchase Agreement, TIC is issuing and selling to
Granite 102,850 shares of TIC's Class A Common Stock and Granite is buying an
additional 154,276 shares of TIC's Class A Common Stock directly from TIC
shareholders. Pursuant to the Rights Agreement, TIC is granting Granite the
right to purchase up to 30% of the total number of outstanding shares of TIC
voting stock during each of the five years after the Effective Date of the
Rights Agreement as well as the right, for a one-month period commencing on the
sixth anniversary of the Effective Date of the Rights Agreement, to acquire
additional shares as will enable it to own 51% of TIC voting stock.
Additionally, Granite will have a right of first purchase in the event TIC
proposes to issue and sell TIC voting stock to third parties. The Rights
Agreement further provides that Granite shall not acquire more than 49.9% of the
outstanding shares of TIC voting stock during the five-year period following the
Effective Date of the Rights Agreement (the "Standstill") except pursuant to its
exercise of its right of first purchase pursuant to the Rights Agreement or its
purchase of TIC stock pursuant to the terms of the Restated Articles of
Incorporation of TIC (the "Restated Articles"). Pursuant to the terms of the
Rights Agreement, TIC reserves the right (the "Call Right") to repurchase all or
any part of the TIC stock owned by Granite upon the occurrence of certain events
(such as a proposed sale of TIC stock by Granite), upon 30 days prior written
notice, and during the one-month period commencing three years after the
Effective Date of the Rights Agreement. If TIC should exercise its Call Right,
Granite's right to purchase 51% of the TIC voting stock will terminate. The
Rights Agreement further provides for the irrevocable waiver by TIC and Granite
of certain repurchase rights they hold pursuant to the terms of the Restated
Articles (the "Waiver").

      Except as otherwise provided, capitalized terms referred to herein have
the meanings set forth in the Stock Purchase Agreement and Rights Agreement, as
appropriate. All section references, unless otherwise indicated, are to the
Internal Revenue Code of 1986, as amended (the "Code").

      In our capacity as legal counsel to Granite in connection with the Stock
Purchase Agreement and Rights Agreement and for the purpose of rendering this
opinion, we have examined and are relying upon (without any independent
investigation or review thereof) the truth and accuracy, at all relevant times,
of the statements, covenants, representations and warranties contained in the
following documents (including all schedules and exhibits thereto): (1) the
Stock Purchase Agreement; (2) the Rights Agreement; (3) Article VI of the
Restated Articles; (4) a certificate from TIC (the "TIC Certificate") that
contains representations with respect to the number of shares of TIC stock
outstanding, the number of shares held by employees that are subject to a right
of first purchase and the number of shares subject to the Waiver; (5) an opinion
of counsel from Otten, Johnson, Robinson, Neff & Rogonetti, P.C. to (the "Otten
Opinion") to the effect that the Rights Agreement, and in particular the Waiver,
is fully enforceable in accordance with its terms, and (6) such other
instruments and documents related to the transactions contemplated by the
parties as we have deemed necessary or appropriate.

      In connection with rendering this opinion, we have assumed or obtained
representations (and are relying thereon, without any independent investigation
or review thereof) that:

            1. Original documents (including signatures) are authentic,
documents submitted to us as copies conform to the original documents, and there
has been (or will be by the Effective Date of the Stock Purchase Agreement and
the Rights Agreement) due execution and delivery of all documents where due
execution and delivery are prerequisites to effectiveness thereof.

            2. Granite's purchase of TIC voting stock will be consummated
pursuant to the terms of the Stock Purchase Agreement and Rights Agreement and
will be effective under the applicable state law.

            3. Any representation or statement made "to the best of knowledge"
or similarly qualified is correct without such qualification. As to all matters
in which a person or entity making a representation referred to above has
represented that such person or entity either is not a party to, does not have,
or is not aware of, any plan or intention, understanding or agreement, there is
in fact no such plan, intention, understanding or agreement.

            4. Granite shall at no time own, acquire or obtain options to
acquire eighty percent (80%) or more of the shares of TIC voting stock.

            5. The Waiver is enforceable according to its terms.
<PAGE>   84
December 30, 1996
Page Three


            6. The Otten Opinion has been delivered and not withdrawn.

            In addition to the assumptions set forth above, this opinion is
subject to the exceptions, limitations and qualifications set forth below.

            Based on our examination of the foregoing items and subject to the
assumptions, exceptions, limitations and qualifications set forth herein, we are
of the opinion that the execution of the Stock Purchase Agreement and the Rights
Agreement by Granite and the consummation of the actions contemplated thereunder
will not render TIC and Granite members of the same "controlled group of
corporations," as that term is defined in Sections 414(b) and 1563 of the Code,
provided that Granite does not subsequently acquire or own or obtain an option
to acquire eighty percent (80%) or more of the shares of TIC voting stock,
regardless of whether such eighty percent (80%) acquisition or ownership by
Granite results from the purchase of additional shares of TIC voting stock by
Granite or the repurchase or redemption by TIC of shares of its voting stock
owned by shareholders other than Granite.

      This opinion represents and is based upon our best judgment regarding the
application of federal income tax laws arising under the Code, existing judicial
decisions, administrative regulations and published rulings and procedures. Our
opinion is not binding upon the Internal Revenue Service ("IRS"), the Department
of Labor ("DOL") or the courts, and the IRS is not precluded from successfully
asserting a contrary position. Furthermore, no assurance can be given that
future legislative, judicial or administrative changes, on either a prospective
or retroactive basis, would not adversely affect the accuracy of the conclusions
stated herein. Nevertheless, we undertake no responsibility to advise you of any
new developments in the application or interpretation of federal tax laws or in
the application or interpretation of the Employee Retirement Income Security Act
of 1974, as amended.

      Our opinion in this letter is based solely upon existing federal law and
federal regulatory and judicial interpretations thereunder that pertain to
controlled group status. We express no opinion as to the enforceability or
validity of the Waiver under federal or Colorado state law. We are not admitted
to practice law in any state or jurisdictions other than the State of
California. Therefore, we are relying solely on the Otten opinion for its
interpretation of federal law and the laws, regulations, and rules of the State
of Colorado with respect to the enforceability of the Waiver.

      This opinion addresses only the classification of TIC and Granite as
members of the same controlled group of corporations under Sections 414(b) and
1563 of the Code. No opinion is expressed as to any other matter or any other
transaction (including any transaction undertaken in connection with these
agreements) under any foreign, federal, state, or local law.

      No opinion is expressed as to any other matter or to any matter whatsoever
if all the terms of the Stock Purchase Agreement and the Rights Agreement are
not carried out in accordance
<PAGE>   85
December 30, 1996
Page Four


with the terms of such Agreements and without waiver or breach of any material
provision thereof or if all of the representations, warranties, statements and
assumptions upon which we relied are not true and accurate at all relevant
times. In the event any one of the statements, representations, warranties or
assumptions upon which we have relied to issue this opinion is incorrect, our
opinion might be adversely affected and may not be relied upon.

      This opinion is intended solely for your benefit and may not be relied
upon by any other person or entity, and may not be made available to any other
person or entity without our prior written consent.


                                                Very truly yours,

P.O. Box 50085
Watsonville, CA 95077

Ladies and Gentlemen:

I am in-house legal counsel to TIC Holdings, Inc., a Colorado corporation
("TIC"). This opinion is delivered to you at the request of TIC pursuant to
paragraph 7.5(a) of that certain Stock Purchase Agreement dated December 23,
1996 (the "Agreement") by and between TIC and Granite Construction Incorporated,
a Delaware corporation ("Buyer"). Unless otherwise defined herein, terms defined
in the Agreement are used herein as therein defined.

In connection with this opinion, I have examined the Agreement and all schedules
and exhibits thereto, and that certain Cooperation and Rights Agreement by and
among TIC, Buyer, and certain shareholders of TIC (the "Rights Agreement"), and
such other records of TIC, certificates and other documents, as I have deemed
necessary or appropriate as a basis for the opinions hereinafter expressed.

This opinion is rendered only with respect to Colorado law and applicable
federal law.

Based upon the foregoing and upon such investigation as I have deemed necessary,
I am of the opinion that:

      (1) The Agreement and the Rights Agreement have been duly executed and
delivered by TIC; and

      (2) As of December 30, 1996, the authorized capital stock of the Company
consists of 2,000,000 shares of preferred stock, par value $1.00 per share, none
of which are issued and outstanding, 2,500,000 shares of Class A Common Stock,
par value of $.10 per share, of which 770,771 shares are issued and outstanding
(not counting the Granite Shares), and 500,000 Shares of Class B Common Stock,
par value of $.10 per share, none of which are issued and outstanding. All such
issued and outstanding shares have been duly authorized and are validly issued,
fully paid and nonassessable. To the best of my knowledge, except as described
in the Disclosure Letter, there are no outstanding rights, options, warrants,
conversion rights or agreements for the purchase or acquisition from the Company
of any shares of its capital stock.

undertaking or obligation to advise Buyer of changes which may hereafter be
brought to my attention.

This opinion has been prepared solely for the use of Buyer and may not be quoted
in whole or in part or otherwise referred to in any financial statement, or
filed with or furnished to any governmental agency or other party, without my
prior written consent. Notwithstanding the foregoing, the law firm of Otten,

                                December 30, 1996


Granite Construction Incorporated
P.O. Box 50085
Watsonville, California 95077


Ladies and Gentlemen:


         We have acted as special counsel to TIC Holdings, Inc., a Colorado
corporation (the "Company") in connection with that certain Stock Purchase
Agreement dated December 23, 1996 (the "Agreement"), by and between the Company
and Granite Construction Incorporated, a Delaware corporation ("Buyer"). This
opinion letter is provided to you at the request of the Company pursuant to
Section 7.5(a) of the Agreement. Except as otherwise indicated herein,
capitalized terms used herein are defined as set forth in the Agreement.

         As special counsel for the Company in connection with this opinion
letter, we have examined the following documents:

         1.       The Agreement.

         2.       That certain Cooperation and Rights Agreement by and among the
                  Company, Buyer and certain shareholders of the Company dated
                  December 23, 1996 (the "Rights Agreement").

         3.       The Articles of Incorporation of the Company, and all
                  amendments thereto which have been duly filed with the
                  Colorado Secretary of State and the bylaws of the Company, as
                  amended to date (the "Organization Documents").

We have also examined such corporate records and other documents and have made
such examination of law as we have deemed necessary in connection with this
opinion letter.

         In rendering this opinion letter, as to questions of fact material to
this opinion letter we have relied, to the extent we have deemed such reliance
appropriate, without investigation, on certificates and other communications
from public officials and others and from directors, officers and employees of
the Company and on representations of the Company set forth in the Agreement.

         Wherever we indicate that our opinion with respect to the existance or
absence of facts is based on our knowledge, our opinion is based solely on the
current actual knowledge of the attorneys in this firm who are representing the
Company in connection with the transactions contemplated by the Agreement
(collectively, the "Contemplated Transactions"), and we have conducted no
special investigation of factual matters in connection with this opinion letter.
With respect to opinions which are qualified by reference to materiality, we
have relied upon the opinions of officers and representatives of the Company.

         In connection with this opinion letter, we have assumed the accuracy
and completeness of all documents and records that we have reviewed, the
genuineness of all signatures, the authenticity of the documents submitted to us
as originals and the conformity to authentic original documents of all documents
submitted to us as certified, conformed or reproduced copies. We have further
assumed that:

                  (i)      Granite has legal existence;

                 (ii)      The Contemplated Transactions have been duly
                           authorized by all necessary corporate or other action
                           on the part of Granite;

                (iii)      All of Granite's representations contained in Section
                           4.3 of the Agreement are true and correct;

                 (iv)      Persons acting on behalf of Granite were duly
                           authorized so to act;

                  (v)      Granite has complied with all legal requirements
                           applicable to it that affect the Contemplated
                           Transactions;

                 (vi)      The Agreement and the Rights Agreement have been duly
                           executed and delivered by Granite;

                (vii)      There has not been any mutual mistake of fact or
                           misunderstanding, fraud, duress or undue influence;
                           and

               (viii)      The Contemplated Transactions comply with any test of
                           good faith or fairness required by law.


         Based upon and subject to the foregoing and subject to the
qualifications and exceptions hereinafter set forth, it is our opinion that:
<PAGE>   95
Granite Construction Incorporated
December 30, 1996
Page 3

         (1)      The Company is a corporation duly organized, validly existing
                  and in good standing under the laws of the State of Colorado.

         (2)      The Company has corporate power and authority to enter into
                  the Agreement and the Rights Agreement and to perform its
                  obligations thereunder. The execution and delivery of the
                  Agreement and the Rights Agreement and the consummation of the
                  Contemplated Transactions have been duly authorised by all
                  necessary corporate action on the part of the Company.

         (3)      Based upon the legal opinion of Michael A. Ross of even date
                  herewith, a copy of which is attached hereto as Exhibit A (the
                  "Ross Opinion"), opining that the Agreement and the Rights
                  Agreement have been duly executed by the Company, such
                  agreements constitute the legal, valid and binding obligation
                  of the Company, enforceable against the Company in accordance
                  with their terms. The provisions set forth in Sections 1.5 and
                  1.6 in the Rights Agreement are valid and binding against the
                  Company and Granite and are fully enforceable in accordance
                  with their terms.

         (4)      The execution and delivery by the Company of the Agreement and
                  the Rights Agreement and the performance of the Company's
                  obligations under such documents, do not violate applicable
                  provisions of statutory law or regulation, subject to
                  compliance with those filing and consent requirements set
                  forth in paragraph (7) below.

         (5)      The execution and delivery of the Agreement and the Rights
                  Agreement and the performance of any of the Contemplated
                  Transactions by the Company will not violate any provision of
                  its Organization Documents, or to our knowledge, based solely
                  on inquiry of officers of the Company, any covenant, indenture
                  or agreement binding upon or affecting the Company or its
                  property or assets, except that under the Company's primary
                  loan facility, the Company will be required to obtain the
                  consent of the lenders prior to granting any security interest
                  in its assets, if and when required by Section 6.1 of the
                  Rights Agreement.

         (6)      The Shares, when issued in compliance with the provisions of
                  the Agreement, including, but not limited to, payment of the
                  Purchase Price by Granite, will be duly authorized, validly
                  issued, fully paid and nonassessable. Except as described in
                  the Agreement (and the Disclosure Letter delivered pursuant
                  thereto) and in the Organisation Documents, the issuance of
                  the Shares is not subject to any preemptive rights or, to our
                  knowledge, rights of first refusal created by the Company.

         (7)      To our knowledge, the Company has obtained all Consents
                  required to be obtained from any person in connection with the
                  execution and delivery of the Agreement or the Rights
                  Agreement or the consummation performance of nay of the
                  Contemplated Transactions, except for (i) the Notification and
                  Report Form which is required to be filed with the Federal
                  Trade Commission and the United States Department of Justice
                  pursuant to the Hart-Scott-Rodino Antitrust Improvements Act
                  of 1976 and the rules and regulations promulgated thereunder,
                  and (ii) the Consent of the Company's primary lenders
                  described in paragraph (5) above; and (iii) such other
                  consents, authorizations, filings, approvals and registrations
                  which if not obtained or made would not have a material
                  adverse effect on the Company.

         (8)      Except as disclosed in the Disclosure Letter, to our
                  knowledge, there is no action, arbitration, hearing,
                  litigation or suit involving any Governmental Authority
                  pending or threatened against the Company, nor is there any
                  Order outstanding against the Company, that, individually or
                  in the aggregate, would reasonably be expected to be Material
                  to the Company.

         (9)      Based solely upon the Ross Opinion (i) the authorized capital
                  stock of the Company consists of 2,000,00 shares of preferred
                  stock, par value $1.00 per share, none of which are issued and
                  outstanding, 2,500,000 shares of Class A Common Stock, par
                  value of $.10 per share, of which 770,771 shares are issued
                  and outstanding, and 500,000 shares of Class B Common Stock,
                  par value $.10 per share, none of which are issued and
<PAGE>   97
Granite Construction Incorporated

Page 5


                  outstanding; (ii) all such issued and outstanding shares have
                  been duly authorized and are validly issued, fully paid and
                  nonassessable; and (iii) except as described in the Disclosure
                  Letter, there are no outstanding rights, options, warrants,
                  conversion rights or agreements for the purchase or
                  acquisition from the Company of any shares of its capital
                  stock.

         We express no opinion to the enforceability of any provisions of the
Agreement or Rights Agreement: (i) that provide that any waivers or amendments
may only be in writing; (ii) which purport to assign or in any way delegate the
fiduciary obligations of members of the board of directors of the Company; (iii)
contained in Section 5 of the Rights Agreement; (iv) which requires the Company
to redeem or repurchase capital stock of the Company at a time in which the
Company has inadequate liquidity and/or assets as prescribed by C.R.S. Section
7-106-401; or (v) as such agreements may be limited by applicable bankruptcy,
insolvency, reorganization, moratorium or other laws of general application
affecting the enforcement of creditors' rights. In addition, Section 4 of the
Rights Agreement, which requires that certain actions be approved by at lease
one of the directors designated by Granite, may not be enforceable based upon
C.R.S. Section 7-108-205 which requires that increased voting requirements be
set forth in the bylaws of the Company. However, the Company has amended its
bylaws to require that at least 73% of the directors in office approve those
actions set forth in Section 4 of the Rights Agreement, therefore, so long as,
Granite designates at lease 30% of the total directors in office, at least one
of the directors designated by Granite will have to vote in favor of such action
in order for the board of directors of the Company to approve such action,
therefore the intended affect of Section 4 should be achieved.

         Our opinions expressed above are limited to the laws of the State of
Colorado and the laws of the United States of America, and we do not express any
opinion herein concerning any other state laws or any ordinances, administrative
decisions, rules or regulations of any county, town, municipality or special
political subdivision (whether created or enabled through legislative action at
the federal, state or regional level). This opinion letter is given as of the
date hereof and we assume no obligation to advise you of changes that may
hereafter be brought to our attention. This opinion letter is solely for the
information of the addressee hereof and is not to be quoted in whole or in part
or otherwise referred to, nor is it to be filed with any governmental agency or
any other person, without our prior written consent. No one other than the
addressee hereof is entitled to rely on this opinion

letter. This opinion letter is rendered solely for purposed of the Contemplated
Transactions and should not be relied upon for any other purpose.
