and has determined that the merger is in your best interests. Accordingly, the
Bowlin board recommends that you vote for adoption of the merger agreement at

                      QUESTIONS & ANSWERS ABOUT THE MERGER

Q:   WHAT DO I NEED TO DO NOW?

A:   Carefully read and consider the information contained in this proxy
     statement/prospectus. Then, please complete, sign and date your proxy and
     return it as soon as possible so that your shares may be represented at the
     special meeting. If you sign and send in your proxy, your shares will be
     voted as you indicate in your proxy. If you sign and send in your proxy,
     but do not indicate how you want to vote, we will count the shares
     represented by your proxy as a vote FOR adoption of the merger agreement.
     If you abstain from voting or do not vote, it will have the effect of a
     vote against the merger agreement.

Q:   CAN I CHANGE MY VOTE AFTER I HAVE MAILED MY SIGNED PROXY?

A:   Yes. You can change your vote at any time before your proxy is voted. You
     can do this in one of three ways. First, you can send a written notice
     stating that you are revoking your proxy. Second, you can complete and
     submit a new proxy dated after the date of your original proxy. If you
     choose either of these two methods, you must submit your notice of
     revocation or your new proxy to the Secretary of Bowlin at 150 Louisiana
     NE, Albuquerque, New Mexico 87108. Third, you can attend the special
     meeting and vote in person. Simply attending the meeting, however, will not
     revoke your proxy; you must also vote at the special meeting.

Q:   IF MY SHARES ARE HELD IN "STREET NAME" BY MY BROKER, WILL MY BROKER VOTE MY
     SHARES FOR ME?

A:   Your broker generally will vote your shares only if you provide
     instructions on how to vote. Follow the information provided to you by your
     broker. If your broker does not vote your shares, it will have the effect
     of a vote against the merger.

Q:   WHAT WILL I RECEIVE IN EXCHANGE FOR MY BOWLIN STOCK IN THE MERGER?

A:   You will receive shares of Class A common stock of Lamar. Assuming the
     exercise of all outstanding Bowlin options, the number of shares of Class A
     common stock of Lamar that you will receive will equal the number of Bowlin
     shares that you own multiplied by .15818.

Q:   WHAT IS THE DIFFERENCE BETWEEN THE LAMAR CLASS A COMMON STOCK THAT I WILL
     RECEIVE IN EXCHANGE FOR MY BOWLIN STOCK IN THE MERGER AND LAMAR'S CLASS B
     COMMON STOCK?

A:   The Class A common stock and the Class B common stock have the same rights
     and powers, except that a share of Class A common stock entitles the holder
     to one vote and a share of Class B common stock entitles the holder to ten
     votes.

Q:   SHOULD I SEND IN MY BOWLIN STOCK CERTIFICATES NOW?

A:   No. After the merger is completed, you will receive written instructions
     for exchanging your stock certificates. Please do not send in your stock
     certificates with your proxy.

Q:   WHEN DO YOU EXPECT THE MERGER TO BE COMPLETED?

A:   We are working toward completing the merger as quickly as possible. If
     approved by the Bowlin stockholders, we expect to complete the merger
     during the first quarter of 2001.

Q:   WHOM SHOULD I CALL WITH QUESTIONS?

A:   You can call Bowlin Investor Relations at (505) 266-5985 with questions
     about the merger.

                                    SUMMARY

     This summary highlights what we believe is the most important information
about the merger. Nonetheless, to fully understand the transaction, you should
read this entire proxy statement/prospectus, including the materials attached as
annexes, as well as the other documents to which we have referred you. See
"Where You Can Find More Information" on page 64 . The page references in
parentheses will direct you to a more detailed description of the topics
presented in this summary.

                                 THE COMPANIES

LAMAR (SEE PAGE 20)

     Lamar is one of the largest and most experienced owners and operators of
outdoor advertising structures in the United States. Lamar also operates the
largest logo sign business in the United States. Lamar has a holding company
structure, in which Lamar Advertising Company and its direct wholly-owned
subsidiary, Lamar Media Corp., serve as holding companies for Lamar's indirect
subsidiaries.

     The principal executive offices of Lamar, a Delaware corporation, are
located at 5551 Corporate Boulevard, Baton Rouge, LA 70808 and its telephone
number at these offices is (225) 926-1000.

BOWLIN (SEE PAGE 20)

     Bowlin is a regional leader in the operation of travel centers and outdoor
advertising displays dedicated to serving the traveling public in rural and
smaller metropolitan areas of the Southwestern United States. The travel center
assets are being "spun off," or transferred, to a separate entity and will not
be a part of Bowlin at the time of the merger.

     The principal offices of Bowlin, a Nevada corporation, are located at 150
Louisiana NE, Albuquerque, New Mexico 87108 and its telephone number at these
offices is (505) 266-5985.

                                   THE MERGER

SUMMARY OF THE TRANSACTIONS (SEE PAGE 38)

     In the proposed merger, Lamar Southwest Acquisition Corporation, a Nevada
corporation and a wholly owned subsidiary of Lamar, will be merged into Bowlin.
Bowlin will be the surviving corporation and its name will be changed to Lamar
Southwest, Inc. On November 1, 2000, Bowlin and its subsidiary, Bowlin Travel
Centers, Inc., entered into a contribution agreement. The contribution agreement
provides that certain assets and liabilities related to Bowlin's travel centers
line of business will be contributed to Bowlin Travel. Bowlin will then
distribute the shares of Bowlin Travel to the Bowlin stockholders immediately
prior to completion of the merger. The business, assets and liabilities of the
travel centers line of business will not, therefore, be acquired by Lamar in the
merger with Bowlin. The shares of Bowlin Travel must be distributed to the
stockholders of Bowlin prior to the consummation of the merger. Also, as part of
the contribution agreement, Bowlin and Bowlin Travel entered into a tax
agreement that provides Bowlin Travel will be responsible for any taxes
resulting from the contribution of the travel centers assets to Bowlin Travel
and the distribution of the shares of Bowlin Travel to the stockholders of
Bowlin.

     The proposed merger will occur following adoption of the merger agreement
by the Bowlin stockholders and satisfaction or waiver of all other conditions to
the merger. The merger agreement is attached as Annex A. We encourage you to
read it because it is the legal document that governs the merger.

                                        2
<PAGE>   8

WHAT THE HOLDERS OF BOWLIN COMMON STOCK WILL RECEIVE IN THE MERGER (SEE PAGE 39)

     In the proposed merger, Bowlin common stockholders will receive Lamar Class
A common stock, which is referred to in this proxy statement/prospectus as
"Lamar stock." When we complete the merger, all of the outstanding shares of
Bowlin common stock, which is referred to in this proxy statement/ prospectus as
"Bowlin stock," will be exchanged for 725,000 shares of Lamar stock. Assuming
the exercise of all outstanding options, each outstanding share of Bowlin stock
will convert into a right to receive .15818 of a share of Lamar stock. Lamar
will not issue any fractional shares of Lamar stock in the merger. Instead,
Bowlin stockholders will receive cash for fractional shares.

MATERIAL FEDERAL INCOME TAX CONSEQUENCES (SEE PAGE 41)

     We intend that the merger qualify as a reorganization within the meaning of
Section 368 of the Internal Revenue Code. If the merger does qualify as a
reorganization, no gain or loss will be recognized by Bowlin, Lamar or the
merger subsidiary by reason of the merger. In addition, you will not recognize
gain or loss on the exchange of your shares of Bowlin stock for shares of Lamar
stock, except for any cash you receive instead of fractional shares.

     BECAUSE THE TAX CONSEQUENCES OF THE MERGER MAY VARY DEPENDING UPON EACH
     BOWLIN STOCKHOLDER'S PARTICULAR CIRCUMSTANCES, WE URGE YOU TO CONSULT YOUR
     OWN TAX ADVISORS ABOUT THE FEDERAL, STATE, LOCAL OR FOREIGN TAX
     CONSEQUENCES TO YOU OF THE MERGER.

APPRAISAL OR DISSENTERS' RIGHTS (SEE PAGE 47)

     Bowlin stockholders do not have appraisal or dissenters' rights in
connection with the merger.

BOWLIN'S REASONS FOR THE MERGER (SEE PAGE 29)

     The Bowlin board concluded that the separation of its two business
segments, the distribution to the Bowlin stockholders of Bowlin Travel stock,
and the merger were in the best interests of Bowlin and its stockholders. In
reaching its decision, the board considered, among other things, its belief
that:

     - the separation of Bowlin into two separate entities, one to operate the
       travel centers business, and the other to operate the outdoor advertising
       business, would improve the travel centers business, and would improve
       the ability of investors to value each business and as a result increase
       stockholder value; and

     - a merger with Lamar Advertising Company would further increase
       stockholder value by giving Bowlin stockholders the opportunity to hold
       shares in a much larger outdoor advertising company with greater
       financial resources and opportunities for growth than Bowlin, as well as
       a more liquid trading market for its shares.

FAIRNESS OPINION OF SANDERS MORRIS HARRIS INC. (SEE PAGE 31)

     In deciding to approve the merger, the Bowlin board considered an opinion
from its financial advisor, Sanders Morris Harris Inc. On October 2, 2000,
Sanders Morris Harris Inc. delivered its written opinion to the Bowlin board
that as of that date and based on and subject to the matters set forth in the
opinion, the consideration pursuant to the merger agreement was fair, from a
financial point of view, to Bowlin stockholders. The full text of this written
opinion is attached as Annex C to this proxy statement/ prospectus. We encourage
you to read this opinion carefully in its entirety. The opinion of Sanders
Morris Harris Inc. is directed to the Bowlin board and is not a recommendation
to any stockholder on how to vote on the merger agreement.

     On that date, there were 4,573,348 shares of Bowlin stock outstanding.
Bowlin stockholders will have one vote at the meeting for each share of common
stock they owned on the record date.

QUORUM; REQUIRED VOTES (SEE PAGE 19)

     The holders of a majority of the outstanding shares of Bowlin stock must be
present, in person or by proxy, at the Bowlin special meeting for there to be a
quorum. To approve the merger, holders of a majority of the outstanding shares
of Bowlin stock must vote to adopt the merger agreement. If you fail to vote or
abstain from voting, it will have the effect of a vote against the merger. A
broker who holds Bowlin stock as your nominee generally will not have authority
to vote your shares unless you provide the broker with voting instructions.

     On the record date, directors and officers of Lamar as a group owned no
shares of Bowlin stock, and directors and officers of Bowlin as a group owned
approximately 58.8% of the outstanding shares of Bowlin stock.

RECOMMENDATION OF THE BOWLIN BOARD (SEE PAGE 29)

     BOWLIN'S BOARD OF DIRECTORS BELIEVES THAT THE MERGER IS IN THE BEST
INTEREST OF BOWLIN STOCKHOLDERS AND RECOMMENDS THAT YOU VOTE "FOR" ADOPTION OF
THE MERGER AGREEMENT.

                           OTHER SELECTED INFORMATION

TREATMENT OF STOCK OPTIONS (SEE PAGE 40)

     Any options for Bowlin stock, other than options to purchase 10,000 shares
of Bowlin stock held by HD Brous & Co., Inc., that had not been exercised by
November 17, 2000, were cancelled and ceased to represent the right to receive
either Bowlin stock or Lamar stock.

EMPLOYEE MATTERS (SEE PAGE 40)

     The Bowlin employees who become employed by Lamar will be eligible to
participate in Lamar's 401(k) plan and any assets held in their respective
accounts of Bowlin's plan will be transferred to Lamar's plan.

ACCOUNTING TREATMENT (SEE PAGE 41)

     Lamar will account for the merger under the purchase method of accounting,
which means the assets and liabilities of Bowlin, including its intangible
assets, will be recorded on Lamar's books at their fair market values. The
results of operations and cash flows of Bowlin will be included in Lamar's
financial statements prospectively as of the closing of the merger.

REGULATORY APPROVALS (SEE PAGE 48)

     United States antitrust laws prohibit Lamar and Bowlin from completing the
merger until we have furnished information and materials about the companies and
the merger to the Antitrust Division of the Department of Justice and the
Federal Trade Commission and the required waiting period has expired. Lamar and
Bowlin have filed the required forms with these government agencies and the
appropriate waiting period has expired. We are not aware of any other
governmental or regulatory approvals required for closing the merger other than
compliance with federal securities laws.

CONDITIONS TO THE MERGER (SEE PAGE 45)

     We must satisfy the following conditions before completing the merger:

     - Bowlin stockholders must adopt the merger agreement; and

     - the registration statement of which this proxy statement/prospectus is a
       part must have been declared effective by the SEC and must not be the
       subject of any stop order or related proceeding.

TERMINATION OF THE MERGER AGREEMENT (SEE PAGE 46)

     We can mutually terminate the merger agreement without completing the
merger. Either Lamar or Bowlin may terminate the agreement if the merger is not
completed by March 31, 2001, and under other circumstances, including failure to
obtain required stockholder approval. Bowlin may terminate the agreement if the
average closing share price of Lamar stock for the 30 trading days ending on the
last trading day immediately prior to the closing of the merger is below $40.00.

TERMINATION FEES AND EXPENSES (SEE PAGE 46)

     If we do not complete the merger, each party generally will pay its own
expenses. If we complete the merger, Lamar will pay all of Bowlin's
merger-related expenses up to $1,250,000. Bowlin Travel will assume any costs
incurred by Bowlin in excess of $1,250,000. Bowlin has agreed to pay Lamar a
termination fee of $580,000 if either party terminates the merger agreement
because Bowlin's stockholders fail to adopt the merger agreement.

COMPARATIVE STOCKHOLDER RIGHTS (SEE PAGE 53)

     When we complete the merger, Bowlin stockholders will hold shares of Lamar
stock. Their rights will thus be governed by Lamar's charter, by-laws and the
Delaware General Corporation Law.

                   LAMAR ADVERTISING COMPANY AND SUBSIDIARIES
                   SELECTED HISTORICAL FINANCIAL INFORMATION

     Lamar is providing the following information to aid you in your analysis of
the financial aspects of the merger. The table below represents selected
historical consolidated statement of operations and balance sheet data of Lamar
and its subsidiaries. Lamar derived this information from audited financial
statements for the years ended October 31, 1995 through October 31, 1996 and
December 31, 1997 through December 31, 1999 and from unaudited financial
statements for the nine months ended September 30, 1999 and September 30, 2000.
Effective January 1, 1997, Lamar changed its fiscal year from a twelve-month
period ending October 31 to a twelve-month period ending December 31.

     In Lamar's opinion, the information for the nine months ended September 30,
1999 and 2000 reflects all adjustments, consisting only of normal recurring
adjustments, necessary to fairly present the results of operations and financial
condition. Results from interim periods should not be considered indicative of
results for any other periods or for the year. This information is only a
summary. You should read it in conjunction with Lamar's historical financial
statements and related notes and the "Management's Discussion and Analysis of
Financial Condition and Results of Operations," which are incorporated by
reference into this proxy statement/prospectus.

    B common stock effective in February 1998.

(2) "EBITDA" is defined as operating income before depreciation and
    amortization. It represents a measure which management believes is
    customarily used to evaluate the financial performance of companies in the
    media industry. However, EBITDA is not a measure of financial performance
    under generally accepted accounting principles and should not be considered
    an alternative to operating income or net earnings as an indicator of
    Lamar's operating performance or to net cash provided by operating
    activities as a measure of its liquidity.

(3) Cash flows from operating, investing and financing activities are obtained
    from the Company's consolidated statements of cash flows prepared in
    accordance with generally accepted accounting principles.

                           COMPARATIVE PER SHARE DATA

     We are providing the following comparative per share information to aid you
in your analysis of the financial aspects of the merger. You should read this
information in conjunction with each of our historical financial statements and
unaudited pro forma consolidated financial statements and the related notes that
are included elsewhere in this proxy statement/prospectus or incorporated into
this proxy statement/ prospectus by reference. The unaudited pro forma
consolidated per share data presented below reflects the purchase method of
accounting for business combinations. The results may have been different if our
companies had always been consolidated. In addition, the per share data of
Bowlin does not reflect the effect of the anticipated spin-off of Bowlin Travel.

     Lamar's fiscal year ends on December 31 and Bowlin's fiscal year ends on
January 31. For purposes of pro forma information (a) Lamar's nine month ended
September 30, 2000 was combined with Bowlin's three month period ended January
31, 2000 and six month period ended July 31, 2000, (b) Lamar's year ended
December 31, 1999 was combined with Bowlin's year ended January 31, 2000 and (c)
Lamar's balance sheet as of September 30, 2000 was combined with Bowlin's
balance sheet as of July 31, 2000. The Bowlin pro forma equivalent per share
data equals the exchange ratio, assuming the exercise of all outstanding
options, of .15818 multiplied by the Lamar pro forma consolidated per share
data. The pro forma per share data are not necessarily indicative of the results
that would have occurred if the merger had been completed on the dates indicated
or the results that will occur after the merger.

                                  RISK FACTORS

     In addition to the other information included in this proxy
statement/prospectus, you should consider carefully the risk factors described
below in deciding how to vote on the merger proposal. It is especially important
that you keep these risk factors in mind when you read forward-looking
statements.

                          RISKS RELATING TO THE MERGER

THE NUMBER OF SHARES OF LAMAR STOCK THAT WILL BE EXCHANGED FOR BOWLIN STOCK IS
FIXED AND WILL NOT BE ADJUSTED IF THERE IS ANY CHANGE IN THE PRICE OF LAMAR
STOCK.

     Assuming the exercise of all outstanding Bowlin stock options, in the
merger, each share of Bowlin stock will be exchanged for .15818 of a share of
Lamar stock. This exchange ratio is based upon the exchange of 725,000 shares of
Lamar stock upon conversion of the Bowlin stock and will not be adjusted as a
result of any change in the price of Lamar stock. The market value of Lamar
stock on and after the closing date of the merger may vary significantly from
the prices on the date of execution of the merger agreement, the date of this
proxy statement/prospectus or the date on which you vote on the merger. Any
change in the price of Lamar stock will affect the value of the consideration
that Bowlin stockholders receive in the merger. On October 3, 2000, the date of
the execution of the merger, the closing price of Lamar stock was $37.44 per
share. On November 29, 2000, the date preceding the filing of this proxy
statement/prospectus, the closing price of Lamar stock was $38.94 per share. We
encourage you to obtain current market quotations for Lamar stock.

LAMAR FACES DIFFERENT MARKET RISKS FROM THOSE FACED BY BOWLIN, AND THESE RISKS
MAY CAUSE THE VALUE OF THE SHARES OF LAMAR STOCK ISSUED TO YOU TO DECLINE.

     In the merger you will receive shares of Lamar stock. The business,
strategy and financial condition of Lamar are somewhat different from that of
Bowlin. Lamar's results of operations, as well as the price of Lamar stock, will
be affected by various factors different from those affecting Bowlin's results
of operations and its common stock price. Future events that may not have
affected the price of Bowlin stock may cause the price of Lamar stock to fall.

OFFICERS AND DIRECTORS OF BOWLIN HAVE CONFLICTS OF INTEREST THAT MAY HAVE
INFLUENCED THEIR DECISIONS REGARDING THE MERGER.

     You should be aware of potential conflicts of interest, and the benefits
available to officers and directors of Bowlin when considering the Bowlin
board's recommendation of the merger. The officers and directors of Bowlin have
interests in the merger that are in addition to, or different from, their
interests as Bowlin stockholders. The Bowlin board was aware of these conflicts
of interest when it approved the merger. These interests include the right of
Bowlin's officers and directors to:

     - exercise options to purchase Bowlin stock at an exercise price that is
       less than the current trading price; and

     - indemnification and insurance coverage with respect to acts and omissions
       in their capacities as officers and directors of Bowlin. For a more
       detailed discussion of potential conflicts of interests of Bowlin
       management, see "Background and Reasons for the Merger -- Potential
       Conflicts of Interests of Bowlin Management in the Merger" on page 37 of
       this proxy statement/prospectus.

                            RISKS RELATING TO LAMAR

LAMAR'S DEBT AGREEMENTS AND THOSE OF ITS WHOLLY-OWNED, DIRECT SUBSIDIARY LAMAR
MEDIA CORP. CONTAIN COVENANTS AND RESTRICTIONS THAT CREATE THE POTENTIAL FOR
DEFAULTS.

     The terms of the indenture relating to Lamar's outstanding notes, Lamar
Media Corp.'s bank credit facility and the indentures relating to Lamar Media's
outstanding notes restrict, among other things, the ability of Lamar and Lamar
Media to:

     - dispose of assets;

     - incur or repay debt;

     - create liens; and

     - make investments.

     Lamar Media's ability to make distributions to Lamar is also restricted
under the terms of these agreements.

     Under Lamar Media's bank credit facility Lamar must maintain specified
financial ratios and levels including:

     - interest coverage;

     - fixed charges ratio;

     - senior debt ratios; and

     - total debt ratios.

     If Lamar fails to comply with these tests, the lenders have the right to
cause all amounts outstanding under the bank credit facility to become
immediately due. If this were to occur and the lenders decide to exercise their
right to accelerate the indebtedness, it would create serious financial problems
for Lamar. Lamar's ability to comply with these restrictions, and any similar
restrictions in future agreements, depends on its operating performance. Because
Lamar's performance is subject to prevailing economic, financial and business
conditions and other factors that are beyond its control, Lamar may be unable to
comply with these restrictions in the future.

BECAUSE LAMAR HAS SIGNIFICANT FIXED PAYMENTS ON ITS DEBT, LAMAR MAY LACK
SUFFICIENT CASH FLOW TO OPERATE ITS BUSINESS AS IT HAS IN THE PAST AND MAY NEED
TO BORROW MONEY IN THE FUTURE TO MAKE THESE PAYMENTS AND OPERATE ITS BUSINESS.

     Lamar has borrowed substantial amounts of money in the past and may borrow
more money in the future. At September 30, 2000, Lamar had approximately $288
million of convertible notes outstanding. At September 30, 2000, Lamar Media had
approximately $1,588 million of debt outstanding consisting of approximately
$1,037 million in bank debt, $541 million in various series of senior
subordinated notes of Lamar Media and $10 million in various other short-term
and long-term debt of Lamar Media.

     A large part of Lamar's cash flow from operations must be used to make
principal and interest payments on its debt. If Lamar's operations make less
money in the future, it may need to borrow to make these payments. In addition,
Lamar finances most of its acquisitions through borrowings under Lamar Media's
bank credit facility which presently has a total committed amount of $1.25
billion in term and revolving credit loans. At September 30, 2000, there was
approximately $212 million available to borrow under this bank credit facility.
Since Lamar's borrowing capacity under Lamar Media's bank credit facility is
limited, Lamar may not be able to continue to finance future acquisitions at
Lamar's historical rates with borrowings under this bank credit facility. Lamar
may need to borrow additional amounts or seek other sources of financing to fund
future acquisitions. Lamar cannot guarantee that additional financing

                                       13
<PAGE>   19

will be available or available on favorable terms. Lamar also may need the
consent of the banks under Lamar Media's bank credit facility, or the holders of
other indebtedness, to borrow additional money.

LAMAR'S BUSINESS COULD BE HURT BY CHANGES IN ECONOMIC AND ADVERTISING TRENDS.

     Lamar sells advertising space to generate revenues. A decrease in demand
for advertising space could adversely affect Lamar's business. General economic
conditions and trends in the advertising industry affect the amount of
advertising space purchased. A reduction in money spent on Lamar's displays
could result from:

     - a general decline in economic conditions;

     - a decline in economic conditions in particular markets where Lamar
       conducts business;

     - a reallocation of advertising expenditures to other available media by
       significant users of Lamar's displays; or

     - a decline in the amount spent on advertising in general.

LAMAR'S OPERATIONS ARE IMPACTED BY THE REGULATION OF OUTDOOR ADVERTISING.

     Lamar's operations are significantly impacted by federal, state and local
government regulation of the outdoor advertising business.

     The federal government conditions federal highway assistance on states
imposing location restrictions on the placement of billboards on primary and
interstate highways. Federal laws also impose size, spacing and other
limitations on billboards. Some states have adopted standards more restrictive
than the federal requirements. Local governments generally control billboards as
part of their zoning regulations. Some local governments have enacted ordinances
which require removal of billboards by a future date. Others prohibit the
construction of new billboards and the reconstruction of significantly damaged
billboards, or allow new construction only to replace existing structures.

     Local laws which mandate removal of billboards at a future date often do
not provide for payment to the owner for the loss of structures that are
required to be removed. Some federal and state laws require payment of
compensation in such circumstances. Local laws that require the removal of a
billboard without compensation have been challenged in state and federal courts
with conflicting results. Accordingly, Lamar may not be successful in
negotiating acceptable arrangements when its displays have been subject to
removal under these types of local laws.

     Additional regulations may be imposed on outdoor advertising in the future.
Legislation regulating the content of billboard advertisements has been
introduced in Congress from time to time in the past. Additional regulations or
changes in the current laws regulating and affecting outdoor advertising at the
federal, state or local level may have a material adverse effect on Lamar's
results of operations.

LAMAR'S CONTINUED GROWTH THROUGH ACQUISITIONS MAY BECOME MORE DIFFICULT AND
INVOLVES COSTS AND UNCERTAINTIES.

     Lamar has substantially increased its inventory of advertising displays
through acquisitions. Lamar's operating strategy involves making purchases in
markets where it currently competes as well as in new markets. However, the
following factors may affect Lamar's ability to continue to pursue this strategy
effectively:

     - The outdoor advertising market has been consolidating, and this may
       adversely affect Lamar's ability to find suitable candidates for
       purchase.

     - Lamar is also likely to face increased competition from other outdoor
       advertising companies for the companies or assets that Lamar wishes to
       purchase. Increased competition may lead to higher prices for outdoor
       advertising companies and assets and decrease those that Lamar is able to
       purchase.

                                       14
<PAGE>   20

     - Lamar does not know if it will have sufficient capital resources to make
       purchases, obtain any required consents from its lenders, or find
       acquisition opportunities with acceptable terms.

     - Lamar must integrate newly acquired assets and businesses into its
       existing operations. From January 1, 2000 to September 30, 2000, Lamar
       completed 71 transactions involving the purchase of complementary outdoor
       advertising assets. The process of integrating these acquisitions may
       result in unforeseen difficulties and could require significant time and
       attention from Lamar's management that would otherwise be directed at
       developing its existing business. Further, Lamar cannot be certain that
       the benefits and cost savings that it anticipates from these purchases
       will develop.

LAMAR FACES COMPETITION FROM LARGER AND MORE DIVERSIFIED OUTDOOR ADVERTISERS AND
OTHER FORMS OF ADVERTISING THAT COULD HURT ITS PERFORMANCE.

     Lamar cannot be sure that in the future it will compete successfully
against the current and future forms of outdoor advertising and other media. The
competitive pressure that Lamar faces could adversely affect its profitability
or financial performance. Although Lamar is the largest company focusing
exclusively on outdoor advertising, it faces competition from larger companies
with more diversified operations which also include radio and other broadcast
media. Lamar also faces competition from other forms of media, including
television, radio, newspapers and direct mail advertising. Lamar must also
compete with an increasing variety of other out-of-home advertising media that
include advertising displays in shopping centers, malls, airports, stadiums,
movie theaters and supermarkets, and on taxis, trains and buses.

     In Lamar's logo sign business, it currently faces competition for
state-awarded service contracts from two other logo sign providers as well as
local companies. Initially, Lamar competes for state-awarded service contracts
as they are privatized. Because these contracts expire after a limited time,
Lamar must compete to keep its existing contracts each time they are up for
renewal.

THE REQUIRED DISPOSITION OF SHARES OF LAMAR STOCK CURRENTLY HELD BY CLEAR
CHANNEL COMMUNICATIONS, INC. COULD CAUSE THE MARKET PRICE OF THE LAMAR STOCK TO
DECLINE.

     A wholly-owned subsidiary of Clear Channel Communications, Inc. currently
holds approximately 26 million shares of Lamar stock. These shares represent
approximately 34.8% of Lamar's outstanding Lamar Class A common stock and 28.4%
of all of Lamar's outstanding common stock as of September 30, 2000. Clear
Channel must dispose of all of these shares prior to January 1, 2003 under the
terms of a consent decree with the Department of Justice. The consent decree was
issued in connection with the merger of AMFM Inc. with Clear Channel, which was
subject to review and clearance by the Federal Trade Commission and U.S.
Department of Justice under the Hart-Scott-Rodino Antitrust Improvements Act of
1976, because Clear Channel is also in the outdoor advertising business. These
shares were originally issued to a subsidiary of AMFM Inc. in connection with
Lamar's acquisition of the Chancellor outdoor advertising business. This
required disposition could adversely affect the market price of Lamar stock.

IF LAMAR'S CONTINGENCY PLANS RELATING TO HURRICANES FAIL, THE RESULTING LOSSES
COULD HURT LAMAR'S BUSINESS.

     Although Lamar has developed contingency plans designed to deal with the
threat posed to its advertising structures by hurricanes, Lamar cannot guarantee
that these plans will work. If these plans fail, significant losses could
result.

     A significant portion of Lamar's structures is located in the Mid-Atlantic
and Gulf Coast regions of the United States. These areas are highly susceptible
to hurricanes during the late summer and early fall. In the past, Lamar has
incurred significant losses due to severe storms. These losses resulted from
structural damage, overtime compensation, loss of billboards that could not be
replaced under applicable laws and reduced occupancy because billboards were out
of service.

     Lamar has determined that it is not economical to obtain insurance against
losses from hurricanes and other storms. Instead, Lamar has developed
contingency plans to deal with the threat of hurricanes. For

                                       15
<PAGE>   21

example, Lamar attempts to remove the advertising faces on billboards at the
onset of a storm, when possible, which permits the structures to better
withstand high winds during a storm. Lamar then replaces these advertising faces
after the storm has passed. However, these plans may not be effective in the
future and, if they are not, significant losses may result.

LAMAR'S LOGO SIGN CONTRACTS ARE SUBJECT TO STATE AWARD AND RENEWAL.

     A portion of Lamar's revenues and operating income come from state-awarded
service contracts for logo signs. Lamar cannot predict what remaining states, if
any, will start logo sign programs or convert state-run logo sign programs to
privately operated programs. Lamar competed with many other parties for new
state-awarded service contracts for logo signs. Even when Lamar is awarded a
contract, the award may be challenged under state contract bidding requirements.
If an award is challenged, Lamar may incur delays and litigation costs.

     Generally, state-awarded logo sign contracts have a term, including renewal
options, of ten to twenty years. States may terminate a contract early, but in
most cases must pay compensation to the logo sign provider for early
termination. Typically, at the end of the term of the contract, ownership of the
structures is transferred to the state without compensation to the logo sign
provider. Of Lamar's 20 logo sign contracts in place at September 30, 2000, two
are subject to renewal in January and February 2001. Lamar cannot guarantee that
it will be able to obtain new logo sign contracts or renew its existing
contracts. In addition, after Lamar receives a new state-awarded logo contract,
it generally incurs significant start-up costs. Lamar cannot guarantee that it
will continue to have access to the capital necessary to finance those costs.

LAMAR'S OPERATIONS COULD BE AFFECTED BY THE LOSS OF KEY EXECUTIVES.

     Lamar's success depends to a significant extent upon the continued services
of its executive officers and other key management and sales personnel. Kevin P.
Reilly, Jr., Lamar's Chief Executive Officer, its nine regional managers and the
manager of its logo sign business, in particular, are essential to Lamar's
continued success. Although Lamar has designed its incentive and compensation
programs to retain key employees, Lamar has no employment contracts with any of
its employees and none of its executive officers have signed non-compete
agreements. Lamar does not maintain key man insurance on its executives. If any
of Lamar's executive officers or other key management and sales personnel
stopped working with Lamar in the future, it could have an adverse effect on
Lamar's business.

LAMAR HAS A CONTROLLING STOCKHOLDER THAT CAN CONTROL ANY VOTES TO EXCLUSION OF
THE OTHER HOLDERS OF LAMAR STOCK.

     Recipients of Lamar stock under this prospectus will have no control over
the management or business practices of the company.

     Kevin P. Reilly, Jr., Chief Executive Officer of Lamar, is the managing
general partner of the Reilly Family Limited Partnership. On September 30, 2000
this partnership beneficially owned all of the outstanding shares of Class B
common stock, which shares represented approximately 69% total voting power of
the Lamar common stock as of September 30, 2000. As a result, Mr. Reilly, or his
successor as managing general partner, controls the outcome of matters requiring
a stockholder vote. These matters include electing directors, amending Lamar's
certificate of incorporation or by-laws, adopting or preventing certain mergers
or other similar transactions, such as a sale of substantially all of Lamar's
assets. Mr. Reilly would also decide the outcome of transactions that could give
the holders of Lamar common stock the opportunity to realize a premium over the
then-prevailing market price for their shares.

     Further, subject to contractual restrictions and general fiduciary
obligations, Lamar is not prohibited from engaging in transactions with
management or its principal stockholders or with entities in which members of
management or Lamar's principal stockholders have an interest. Lamar's
certificate of incorporation does not provide for cumulative voting in the
election of directors and, consequently, the Reilly Family Limited Partnership
can elect all the directors.

                                       16
<PAGE>   22

LAMAR'S BY-LAWS AND CERTIFICATE OF INCORPORATION CONTAIN CERTAIN ANTI-TAKEOVER
PROVISIONS THAT MAY MAKE IT HARDER TO REALIZE A PREMIUM OVER THE COMMON STOCK'S
MARKET PRICE OR MAY AFFECT THE MARKET PRICE OF LAMAR STOCK.

     Provisions of Lamar's certificate of incorporation and by-laws may
discourage a third party from offering to purchase Lamar. These provisions,
therefore, inhibit actions that would result in a change in control of Lamar.
Some of these actions would otherwise give the holders of Lamar stock the
opportunity to realize a premium over the then-prevailing market price of the
stock.

     These provisions may also adversely affect the market price of Lamar stock.
For example, under Lamar's certificate of incorporation Lamar can issue "blank
check" preferred stock with such designations, rights and preferences as Lamar's
board of directors determines from time to time. If issued, this type of
preferred stock could be used as a method of discouraging, delaying or
preventing a change in control of Lamar. In addition, if Lamar issues preferred
stock, it may adversely affect the voting and dividend rights, rights upon
liquidation and other rights that holders of the common stock currently hold.
Lamar does not currently intend to issue any shares of this type of preferred
stock, but retains the right to do so in the future.

     Furthermore, Lamar is subject to Section 203 of the Delaware General
Corporation Law, which may discourage takeover attempts. Section 203 generally
prohibits a publicly held Delaware corporation from engaging in a business
combination with an "interested stockholder" for a period of three years after
the date of the transaction in which the person became an interested
stockholder.

YOU MAY NOT RECEIVE ANY CASH DIVIDENDS ON THE LAMAR STOCK.

     Lamar has never paid cash dividends on its Class A common stock and does
not plan to do so in the foreseeable future.

                           THE BOWLIN SPECIAL MEETING

INTRODUCTION

     This proxy statement/prospectus is being furnished to the stockholders of
Bowlin Outdoor Advertising and Travel Centers in connection with the special
meeting of stockholders of Bowlin to be held on January 19, 2001, and any
postponement or adjournment of that meeting. The approximate date this proxy
statement/prospectus is first being sent to Bowlin stockholders is December 14,
2000.

ACTION TO BE TAKEN AT THE BOWLIN SPECIAL MEETING

     At the special meeting, holders of common stock, $.001 par value, of Bowlin
will be asked to consider and vote on a proposal to adopt the merger agreement
and to transact any other business that properly comes before the meeting. The
merger agreement is attached as Annex A to this proxy statement/ prospectus and
is incorporated herein by reference.

VOTING AT THE BOWLIN SPECIAL MEETING

     Only stockholders of record at the close of business on December 11, 2000
will be entitled to vote at the special meeting. As of the close of business on
December 11, 2000, 4,573,348 shares of Bowlin stock were outstanding and
entitled to vote at the special meeting.

     Any person giving a proxy in the form accompanying this proxy
statement/prospectus has the power to revoke it at any time before its exercise.
The proxy may be revoked by filing with the Secretary of Bowlin an instrument of
revocation or a duly executed proxy bearing a later date. The proxy also may be
revoked by affirmatively electing to vote in person while attending the special
meeting. A stockholder who attends the meeting, however, need not revoke the
proxy and vote in person unless the stockholder wishes to do so. All valid,
unrevoked proxies will be voted at the special meeting in accordance with the
instructions given. IF THE SIGNED PROXY IS RETURNED WITHOUT INSTRUCTIONS, IT
WILL BE VOTED FOR ADOPTION OF THE MERGER AGREEMENT. A majority of the shares of
the Bowlin stock entitled to vote, present in person or represented by proxy,
will constitute a quorum at the special meeting. The affirmative vote of the
holders of a majority of the shares of outstanding Bowlin stock is required to
adopt the merger agreement. Abstentions have the same effect as "no" votes in
determining whether the proposal is approved. Broker non-votes are counted for
purposes of determining whether a quorum exists at the special meeting and have
the same effect as "no" votes in determining whether the proposal is approved.
Although the Notice of Special Meeting of Bowlin Outdoor Advertising and Travel
Centers Stockholders provides for transaction of any other business as may
properly come before the meeting, the board of directors of Bowlin has no
knowledge of any matters to be presented at the meeting other than those
referred to herein. The accompanying proxy, however, gives discretionary
authority to the proxy holders to vote in accordance with the recommendation of
management if any other matters are presented.

SOLICITATION OF PROXIES

     The accompanying proxy is being solicited on behalf of the board of
directors of Bowlin. The expense of preparing, printing, and mailing the form of
proxy and the material used in the solicitation thereof will be borne by Lamar
Advertising Company. See "Termination Fees and Expenses." In addition to the use
of the mails, proxies may be solicited by personal interview, telephone, and
telegram by directors, officers, and employees of Bowlin. Arrangements have also
been made with brokerage houses, banks, and other custodians, nominees, and
fiduciaries for the forwarding of solicitation materials to the beneficial
owners of Bowlin stock held of record by such person, and Bowlin will reimburse
them for reasonable out-of-pocket expenses they incur.

                               BUSINESS OF LAMAR

     Lamar is one of the largest and most experienced owners and operators of
outdoor advertising structures in the United States. Lamar conducts a business
that has operated under the Lamar name since 1902. As of September 30, 2000,
Lamar operated approximately 130,600 displays in 43 states. Lamar also operates
the largest logo sign business in the United States. Logo signs are signs
located near highway exits which deliver brand name information on available
gas, food, lodging and camping services. As of September 30, 2000, Lamar
maintained over 89,000 logo sign displays in 20 states. Lamar also operates
transit advertising displays on bus shelters, bus benches and buses in several
markets.

                              RECENT DEVELOPMENTS

COMPLETED ACQUISITIONS

     From January 1, 2000 to September 30, 2000, Lamar completed 71 acquisitions
of complementary outdoor advertising assets, for an aggregate price of
approximately $488 million. These acquisitions included approximately 15,400
displays. Lamar expects that these acquisitions will allow it to take advantage
of operating efficiencies and cross-market sales opportunities.

PENDING ACQUISITIONS

     As of September 30, 2000, Lamar had entered into agreements relating to
several other acquisitions which are pending, including the acquisition of
Bowlin that is the subject of this proxy statement/ prospectus. If Lamar
completes all of these acquisitions, it will acquire approximately 6,200 outdoor
advertising displays for an aggregate purchase price of approximately $119
million. These acquisitions are subject to various conditions including the
satisfaction of customary closing conditions. Lamar cannot be sure whether or
when these acquisitions will be completed.

                               BUSINESS OF BOWLIN

     For the most current description of Bowlin Outdoor Advertising and Travel
Centers business, please see Bowlin's annual report on Form 10-K for the fiscal

       BOWLIN MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                           AND RESULTS OF OPERATIONS

OVERVIEW

     The following is a discussion of the consolidated financial condition and
results of operations of Bowlin as of and for the periods ended July 31, 2000
and 1999. This discussion should be read in conjunction with the Consolidated
Financial Statements of Bowlin and the related notes included in Bowlin's Form
10-K for the fiscal year ended January 31, 2000, which is enclosed with this
proxy statement/prospectus as Annex D.

     Bowlin operates in two industry segments: outdoor advertising and travel
centers. In order to perform a meaningful evaluation of Bowlin's performance in
each of its operating segments, Bowlin has presented selected operating data
which separately sets forth the revenue, expenses and operating income
attributable to each segment, and also separately sets forth the corporate
expenses of Bowlin which management does not allocate to either of Bowlin's
segments for purposes of determining their respective operating income. The
discussion of results of operations which follows compares such selected
operating data and corporate expense data for the interim periods presented.

RESULTS OF OPERATIONS

     The following table presents certain income and expense items derived from
the Consolidated Statements of Income for the six and three months ended July 31
(unaudited and amounts in thousands):

(1) EBITDA is defined as operating income before depreciation and amortization.
    It represents a measure which management believes is customarily used to
    evaluate the financial performance of companies in the media industry.
    However, EBITDA is not a measure of financial performance under generally
    accepted accounting principals and should not be considered an alternative
    to operating income or net income as an indicator of Bowlin's operating
    performance or to net cash provided by operating activities as a measure of
    its liquidity.

  Comparison of the Six Months Ended July 31, 2000 and July 31, 1999

     OUTDOOR ADVERTISING.  Gross sales from Bowlin's outdoor advertising
increased 11.1% to $4.261 million for the six months ended July 31, 2000, from
$3.836 million for the six months ended July 31, 1999. The increase was
primarily attributable to the continual assimilation of Bowlin's acquisitions,
internal development, increased usage of available sign inventory, and increases
in rates.

     Direct operating expenses related to outdoor advertising consist of rental
payments to property owners for the use of land on which advertising displays
are located, production expenses and selling expenses. Selling expenses consist
primarily of salaries and commissions for salespersons and travel related to
sales. Direct operating costs increased 14.8% to $1.967 million for the six
months ended July 31, 2000, from $1.713 million for the six months ended July
31, 1999. The increase is principally due to increases in salaries, sign
repairs, cost of production and utilities. Direct operating expenses as a
percentage of gross revenues for the six months ended July 31, 2000 was 46.2%
compared to 44.7% for the six months ended July 31, 1999.

six months ended July 31, 2000, from $846,000 for the six months ended July 31,
1999. The increase is attributable to scheduled depreciation of advertising
display structures as well as the amortization of goodwill and non-compete
covenants.

     The above factors contributed to the increase in outdoor advertising
operating income of 2.0% to $778,000 for the six months ended July 31, 2000,
from $763,000 for the six months ended July 31, 1999.

months ended July 31, 2000, from $291,000 for the six months ended July 31,

insurance proceeds in fiscal year 2000 not present in fiscal year 2001.

     Income before income taxes decreased 25.4% to $572,000 for the six months

million for the six months ended July 31, 1999. At July 31, 2000 and 1999,
financing activities were primarily a result of borrowings and payments on debt.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

     The principal market risks Bowlin is exposed to are interest rates on
Bowlin's debt. Bowlin's interest sensitive liabilities are its debt instruments.
Variable interest on the majority of Bowlin's debt equals LIBOR plus an
applicable margin. Because rates may increase or decrease at any time, Bowlin is
exposed to market risk as a result of the impact that changes in these base
rates may have on the interest rate applicable to Bowlin's borrowings.
Management does not, however, believe that any risk inherent in the variable
rate nature of its debt is likely to have a material effect on Bowlin's
financial position, results of operations or liquidity.

                     BACKGROUND AND REASONS FOR THE MERGER

BACKGROUND

     The terms and conditions of the merger were determined through arm's length
negotiations between the senior managements, boards of directors and financial
advisors of Lamar and Bowlin. In determining the form of the transaction and the
form and amount of the consideration, numerous factors were reviewed by the
senior managements and boards of directors of Lamar and Bowlin. The following is
a brief discussion of the contacts and negotiations that have occurred between
Lamar and Bowlin.

     Prior to the beginning of the year, the board of directors and senior
management of Bowlin and Rudy R. Miller, Chairman, President and CEO of Miller
Capital Corporation, Bowlin's financial advisor, discussed structuring the
company so as to maximize stockholder value. Because Bowlin operated two very
separate and distinct businesses (outdoor advertising and travel centers), it
was uncertain that the trading price of Bowlin's common stock was capturing the
value of each of the business operations.

     In mid January 2000, after consultation with, and at the request of, the
board of directors of Bowlin, Miller Capital contacted REGENT Communications,
Inc.; Eller Outdoor, a part of Clear Channel; Outdoor Systems, a part of
Infinity Broadcasting; and Lamar Advertising Company, to discuss a possible
transaction. At that time, Miller Capital mailed public information to REGENT,
Outdoor Systems and Lamar. Of the companies contacted, Lamar was the only
company that expressed an interest in pursuing negotiations with Bowlin.

     On March 27, 2000, a meeting was held in Baton Rouge, Louisiana where Lamar
is headquartered. Attending the meeting were:

         Kevin Reilly, Chairman of the Board, President and CEO, Lamar

         Sean Reilly, Board member and Vice President/Director of Acquisitions,
         Lamar

         Rod Rackley, Vice President Real Estate, Lamar

         Mike Bowlin, Chairman, President and CEO, Bowlin

         Chris Bess, Executive Vice President and COO, Bowlin

         Rudy Miller, Chairman, President and CEO, Miller Capital

At this meeting Lamar provided a list of additional information they required to
evaluate a potential transaction. Bowlin assembled the requested diligence
materials on or about May 10, 2000.

     On April 13, 2000, Bowlin announced its fiscal year financial results. In
that announcement, Michael Bowlin, Chairman, President and Chief Executive
Officer of Bowlin stated that the company believed that its stock remained
"undervalued when applying an analysis of Bowlin's assets as compared to other
outdoor related companies with a standard industry multiple of EBITDA." Mr.
Bowlin also stated that the company continued to analyze strategies that
included both the outdoor advertising business and the travel centers business
that might enhance stockholder value.

     On May 5, 2000, the board of directors of Bowlin held a meeting to discuss
further a plan to enhance stockholder value. The board discussed separating its
two business segments into separate entities, contributing all of the travel
center assets and liabilities to a new travel center entity, and pursuing a
separate transaction or disposition of the outdoor advertising business.

     Negotiations between Lamar and Bowlin continued. Throughout the process,
all communications between Lamar and Bowlin were mediated through Miller
Capital.

     On June 8, 2000, Bowlin announced its financial results for the quarter
ended April 30, 2000. In that press release, Mr. Bowlin stated that the company
was actively pursuing transactions to accomplish the separation of the outdoor
advertising company and the travel centers business to enhance stockholder
value.

                                       28
<PAGE>   34

     On June 15, 2000, Lamar submitted a letter of intent to Bowlin, indicating
that it was interested in pursuing an acquisition of the outdoor advertising
business.

     On June 22, 2000, Mike Bowlin signed the letter of intent.

     At that time Bowlin brought in their outside counsel, Squire, Sanders &
Dempsey, and in concert with Miller Capital and Bowlin's senior management,
began working on a definitive agreement for the transaction.

     On September 11, 2000, Bowlin retained Sanders Morris Harris Inc., Houston,
Texas, a registered broker/dealer to review all aspects of the transaction and
to prepare and issue a fairness opinion to Bowlin.

     On September 13, 2000, Bowlin announced its financial results for the
quarter ended July 31, 2000. In that press release Mr. Bowlin stated that the
company was moving forward with the previously announced plan to divide the
company into two separate operating entities and that it expected to announce
the details and time frame of the process within the next 30 days.

     On September 14, 2000, the board of directors of Bowlin met, along with
Miller Capital and Squire, Sanders & Dempsey, to discuss the potential
transaction with Lamar. The board discussed in detail the acquisition by Lamar,
the contribution of assets and liabilities to a newly formed subsidiary, Bowlin
Travel Centers, Inc., the registration of the shares of Bowlin Travel Centers,
and the anticipated spin-off of the shares of Bowlin Travel Centers to the
stockholders of Bowlin.

     On September 29, 2000, Bowlin held another special board meeting, which
included Sanders Morris Harris Inc., Miller Capital and Squire Sanders as
meeting guests, to discuss the fairness opinion issued by Sanders Morris Harris
Inc. This meeting provided board members another opportunity to ask additional
questions from all the outside professionals invited to participate in the
meeting. At this meeting, the board concluded that the transaction was fair to
the stockholders from a financial point of view and in the best interest of
Bowlin and its stockholders and approved the definitive agreement in
substantially the form presented to the board at that meeting.

     On October 3, 2000, a definitive agreement was signed by Lamar and Bowlin.

     Directors and officers of Bowlin have interests in the merger different
from the interests of other Bowlin stockholders. See "Potential Conflicts of
Interest of Bowlin Management in the Merger."

BOWLIN'S REASONS FOR THE MERGER

     The following discussion of Bowlin's reasons for the merger contains a
number of forward-looking statements that reflect the current views of Bowlin
with respect to future events that may have an effect on their future financial
performance. These forward-looking statements include statements regarding the
markets for Lamar's, Bowlin's and the combined company's services, their planned
response to the demands of their markets, their business strategies, and certain
potential technological and operating synergies intended to be achieved by the
merger. These forward-looking statements are subject to various risks and
uncertainties that could cause actual results of Lamar, Bowlin and the combined
company to differ materially from those currently anticipated, including the
ability of Lamar and Bowlin to successfully integrate their operations and
achieve expected synergies; the ability of Bowlin to retain key employees
following announcement of the merger; changes in business conditions and growth
trends affecting Lamar's and Bowlin's markets, the outdoor advertising industry
and the economy in general; and a variety of other competitive factors. These
and other factors that could cause actual results to differ materially are
described under "Risk Factors" and elsewhere in this proxy statement/prospectus.

     The Bowlin board believes that the terms of the merger are fair to, and in
the best interests of, Bowlin and its stockholders. ACCORDINGLY THE BOWLIN BOARD
HAS APPROVED THE PROPOSED MERGER AND RECOMMENDS THAT BOWLIN STOCKHOLDERS VOTE
FOR ADOPTION OF THE MERGER AGREEMENT. In reaching their

                                       29
<PAGE>   35

decision, the directors considered, with the assistance of management and its
legal and financial advisors, the following factors:

     - the financial and other terms and conditions of the merger agreement,
       including the 725,000 shares of Lamar stock being offered to the
       stockholders of Bowlin in exchange for their Bowlin stock;

     - the fact that Bowlin's obligation to consummate the merger is conditioned
       upon the approval of Bowlin's stockholders and other conditions as set
       forth in the merger agreement;

     - the historical market price of, and recent trading activity in, the Lamar
       stock;

     - the opportunity for Bowlin stockholders to participate in the long-term
       growth and appreciation of Bowlin's business through their ownership
       interest in Lamar;

     - the strategic fit between the outdoor advertising businesses of Bowlin
       and Lamar;

     - anticipated cost savings resulting from the merger, including (a) the
       consolidation of corporate, administrative and support functions, and (b)
       the elimination of public reporting obligations of Bowlin (the Bowlin
       board did not consider any quantified amount of such cost savings in
       reaching its decision to engage in the merger);

     - the opinion of Sanders Morris Harris Inc. that, as of October 2, 2000,
       the consideration to be paid in the transaction is fair, from a financial
       point of view, to the Bowlin stockholders (See "Fairness Opinion of
       Bowlin's Financial Advisor");

     - the financial presentation and analysis of Sanders Morris Harris Inc.
       prepared in connection with its fairness opinion;

     - the familiarity of the board with the business, results of operations,
       properties and financial condition of Bowlin and the nature of the
       industry in which it operates;

     - the Bowlin board considered the financial and other terms of the merger,
       including the fact that Bowlin's board is prevented from seeking out
       alternative transactions under the merger agreement; notwithstanding this
       restriction, the Bowlin board may provide information to or enter into
       discussions or negotiations with other persons if it determines that it
       is necessary to fulfill the directors' fiduciary duties to Bowlin's
       stockholders;

     - publicly available information with respect to the financial condition
       and business of Lamar, including, among other things, Lamar's recent
       operating performance and future prospects;

     - the capital structure of Lamar;

     - reports from management and legal advisors on specific terms of the
       merger agreement;

     - information received concerning the financial performance, condition,
       business operations and prospects of each of Bowlin and Lamar; and

     - the proposed terms, timing and structure of the merger.

     The Bowlin board also considered a number of risks associated with the
merger, including:

     - the possibility of management disruption associated with the merger and
       the risk that, despite the efforts of the combined company, key
       management personnel of Bowlin might not continue their employment with
       the combined company;

     - the possibility that certain of the operating economies of scale such as
       the elimination of redundant administrative costs sought to be achieved
       as a result of the merger might not be realized; and

     - the possibility of Bowlin's failure to be successfully integrated into
       Lamar.

     On balance, however, the Bowlin board determined that the benefits of the
merger outweighed the potential risks and approved the merger.

     The foregoing discussion of information and factors considered by the
Bowlin board is not intended to be exhaustive but is intended to include the
material factors considered. In view of the wide variety of factors considered,
the Bowlin board did not find it practical to, and did not, quantify or
otherwise assign relative weight to the specific factors considered and
individual directors may have given different weights to different factors.

OPINION OF FINANCIAL ADVISOR TO BOWLIN'S BOARD OF DIRECTORS

     The Bowlin board retained Sanders Morris Harris Inc., who we refer to as
SMH, to act as its financial advisor in connection with the proposed transaction
and to render an opinion as to the fairness, from a financial point of view, to
the stockholders of Bowlin of the consideration to be received in the proposed
transaction. SMH is an independent investment banking firm that has no ownership
interest in Bowlin and that is not an affiliate of Bowlin. On October 2, 2000,
SMH rendered its opinion to the board of directors of Bowlin to the effect that,
as of such date and based upon and subject to the various considerations
described in the opinion, the consideration was fair, from a financial point of
view, to the stockholders of Bowlin.

     The full text of SMH's written opinion dated as of October 2, 2000 which
sets forth, among other things, the assumptions made, matters considered, and
scope and limitations on the review undertaken, is attached as Annex C hereto
and is incorporated by reference. Stockholders are urged to, and should, read
SMH's opinion carefully and in its entirety. SMH's opinion was prepared for the
use of the board of directors in connection with the transaction and does not
address the relative merits of the proposed transaction or constitute a
recommendation to the stockholders as to how they should vote in connection with
the transaction. In addition, the opinion addresses only the financial fairness
of the terms of the transaction to the stockholders and does not address the
relative merits of the transaction or any alternatives, the underlying decision
of the board to engage in the transaction or any other aspect of the
transaction. The summary of SMH's opinion set forth below is qualified in its
entirety by reference to SMH's opinion and should be read together with the full
text of the opinion.

     In arriving at its opinion, SMH has, among other things:

          1. Reviewed a draft of the Agreement and Plan of Merger dated
     September 20,2000;

          2. Reviewed a Letter of Intent from Lamar dated June 15, 2000;

          3. Reviewed Bowlin's audited financials and annual reports for the
     years ended January 31, 2000 and January 31, 1999;

          4. Reviewed Bowlin's unaudited financial statements for the quarters
     ended July 31, 2000 and April 30, 2000;

          5. Reviewed Lamar's audited financial statements for the year ended
     December 31, 1999;

          6. Reviewed Lamar's unaudited financial statements for the six months
     ended June 30, 2000;

          7. Reviewed Lamar's Form S-3 (i.e., prospectus relating to the sale of
     26.2 million shares of Lamar by Clear Channel Communications) dated
     September 8, 2000;

          8. Reviewed Bowlin's Form 10 (i.e., registration statement for the
     travel centers spin-off) draft dated September 14, 2000;

          9. Reviewed Bowlin management's outdoor advertising segment budget for
     the year ending January 31, 2001;

          10. Reviewed historical market prices and trading volume for common
     stocks of both Bowlin and Lamar;

          11. Reviewed recent Lamar equity research reports;

                                       31
<PAGE>   37

          12. Reviewed a 1999 Confidential Memorandum prepared by Miller Capital
     Corporation regarding the sale of Bowlin's travel center segment;

          13. Reviewed Bowlin's December 17, 1996 Prospectus prepared by HD
     Brous & Co., Inc.;

          14. Discussed various assets, liabilities and operations of Bowlin
     involved in the transaction; and

          15. Reviewed such other financial studies and analyses and performed
     such other investigations as SMH deemed appropriate.

     In conducting its analyses, SMH also held discussions with members of
Bowlin's senior management regarding the past and current business operations,
financial condition and future prospects of Bowlin. SMH assumed that the merger
agreement had been executed and delivered by the parties thereto on terms
substantially the same to those contained in the most recent draft thereof
supplied to and reviewed by SMH as of the date of its opinion. SMH relied upon
and assumed the accuracy and completeness of the financial and other information
made available to it and did not assume responsibility for independent
verification of such information. SMH assumed, and the management of Bowlin has
represented, that the information provided by Bowlin, including projections, had
a reasonable basis and reflected the best currently available estimates and
judgments of Bowlin's management as to the recent and likely future performance
of Bowlin. SMH also relied on representations of Bowlin's management that they
were not aware of any information or fact that would make the information
provided to SMH incomplete or misleading.

     In rendering its opinion, SMH assumed and relied upon, without independent
verification, the accuracy and completeness of all information reviewed by it
for the purposes of its opinion. SMH assumed that the transaction would be
consummated on the terms set forth in the merger agreement and that, in the
course of obtaining necessary regulatory and third-party consents for the
transaction, no restriction would be imposed that would have a material adverse
effect on the future results of operations or financial condition of Bowlin. SMH
did not make any independent valuation or appraisal of the assets or liabilities
of Bowlin. SMH's opinion was necessarily based on economic, market, financial
and other conditions as they existed on, and on the information made available
to SMH as of, the date of such opinion. It should be understood that, although
subsequent developments may affect its opinion, except as agreed upon by Bowlin,
SMH does not have any obligation to update, revise or reaffirm its opinion.

     In arriving at its opinion, SMH was not authorized to solicit, and did not
solicit, indications of interest from any potential buyers of part or all of
Bowlin nor did it have discussions with any party other than Bowlin's affiliates
with respect to the acquisition of Bowlin or any of its assets. Furthermore, SMH
was not authorized to negotiate the terms of the transaction and has based its
opinion solely on the terms of the merger agreement as negotiated by others.

     The following is a summary of the most significant factors considered and
the principal financial analyses performed by SMH to arrive at its opinion dated
October 2, 2000:

     (1) Value Range Comparison. SMH's fairness analysis was primarily that the
         value received per share for 100% of Bowlin was equal to or greater
         than the midpoint of the range of fair market value per share for 100%
         of Bowlin's common stock given up by its stockholders. The following
         table summarizes SMH's Value Range Comparison:

<TABLE>
        <S>                                                           <C>
        Estimated Fair Market Value Per Share of Bowlin Stock "Given
          Up".......................................................  $6.00-$7.00
        APPROXIMATE MID-POINT VALUE OF STOCK "GIVEN UP".............        $6.50
        Estimated Fair Market Value Per Share for approximately
          0.165 Shares of Lamar Stock...............................        $6.61(A)
        "Received" for Each Share of Bowlin Stock
        Additional Value Per Share "Received" from Spin-Off of
          Travel Center Division....................................  $1.50-$3.00
        Approximate Mid-Point.......................................        $2.25
        Total Range of "Value Received".............................  $8.11-$9.61
        APPROXIMATE MID-POINT OF TOTAL VALUE "RECEIVED".............        $8.86
        Premium of $8.86 over $6.50.................................           36%
</TABLE>

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

        (A) Based on a minimum Lamar price of $40.00 per share.

        Since the mid-point of the value per share of 100% of Bowlin's common
        stock "given up" by its stockholders was approximately $6.50 and the
        "value received" for (a) the Lamar common stock and (b) the travel
        center spin-off was $8.86 per share, the exchange appeared to be fair to
        Bowlin's stockholders. SMH also noted that Lamar has a much larger
        market capitalization and a more liquid market for its stock than
        Bowlin's stock.

     (2) Analysis of value for Bowlin stock. In valuing Bowlin's stock, SMH
         believed the current stock market price, recent historical stock prices
         as well as past and current Bowlin financials were the best indicators
         of fair market value. Based on Bowlin's October 1, 2000 stock market
         price of $6.50 per share, Bowlin's past trading history and a review of
         Bowlin's financial information, SMH believed the range of fair market
         value for Bowlin's common stock was between $6.00 and $7.00 per share,
         with a mid-point of $6.50.

     (3) Analysis of value for Lamar common stock. Based on Lamar's relatively
         large market capitalization, recent trading history, analyst comments
         and valuations from recent equity research reports on Lamar, and SMH's
         overall business judgment, SMH believed the current fair market value
         per share of Lamar's common stock was approximately $35.00-$45.00, with
         a mid-point of $40.00. In applying this mid-point to BOWLIN stock, SMH
         multiplied 725,000 shares to be issued to Bowlin stockholders by the
         $40.00 mid-point (i.e., $29.0 million) and then divided by 4,390,098
         total outstanding shares of Bowlin stock to arrive at $6.61 per share
         of value "received" per share of Bowlin "given up" by its stockholders.

     (4) Analysis of value for 100% of the Travel Center Division.

        - EBITDA multiple valuation. SMH began by calculating a preliminary
          enterprise value for the travel center division. A range of multiples
          was applied, but a midpoint of 6 was used in the analysis. SMH then
          applied the 6 multiple to the average of the travel center division's
          fiscal 2000 earnings before interest, taxes, depreciation and
          amortization ("EBITDA") and the first 6 months of fiscal 2001
          annualized EBITDA. This gave an implied equity value per share of
          $1.22 ($10.0 million minus $6.6 million of debt plus $1.9 million of
          cash divided by 4.4 million shares) for the travel center division.

        - Discounted Cash Flow Analysis. SMH's primary methodology to value the
          travel center division was a discounted cash flow analysis (i.e., an
          internal rate of return or IRR analysis),

                                       33
<PAGE>   39

          which is one method SMH believes investors use to evaluate similar
          businesses and divisions. SMH discussed appropriate assumptions for
          such analysis with BOWLIN management on September 15, 2000 and on
          September 21, 2000. SMH began with fiscal 2001 estimated EBITDA and
          grew EBITDA at 5% per year based on discussions with management. SMH
          used a pre-tax discount rate of 15% because of the risk involved in
          investments in this industry and used the present value of 4-6 times
          2005 estimated EBITDA as the terminal value. Based on these
          parameters, SMH arrived at an implied fair market value for 100% of
          the division's equity of $10.1 million, or $2.31 per share.

        Based on SMH's valuations of the travel center division, but giving more
        weight to its DCF analysis, SMH believed the travel center division's
        fair market value was $1.50-$3.00 per share. Although the financial
        analyses employed by SMH imply a market value for 100% of the division,
        SMH does not express an opinion on what the travel center division's
        stock might trade for after the spin-off. The values implied by the
        analyses do not purport to suggest future trading prices for the stock
        of the spin-off company.

     (5) Premium Over Recent Stock Prices. SMH believed a premium of 30-40% was
         clearly fair and attractive to a Bowlin stockholder whose alternative
         at the time of SMH's analysis was to sell the stock at $6.50. Such
         premiums can range from zero to more than 100% due to special
         circumstances, but SMH believed a normal range was probably 20-60%
         based on industry and size of operations.

        As reported in Mergerstat Review, average premiums offered for 1999 and
        1998 were 43.3% and 40.7%, respectively. Reported figures for 1999 were
        based on 723 announced public deals and 1998 were based on 523 announced
        public deals. Mergerstat defines premiums offered as price over seller's
        closing market price five days prior to announcement.

     (6) Comparable Company Analysis for Bowlin Travel.  Since the companies
         used in this analysis were not very comparable to Bowlin (due to their
         size and business mix) and the fact that the multiples derived were
         extremely high in comparison to most companies, SMH did not give any
         weight to the analysis. Nevertheless, SMH reviewed certain financial
         ratios for the following public companies:

        - Infinity Broadcasting Corporation

        - Obie Media Corporation

        - Lamar Advertising Company

        The three key valuation multiples used in their analysis were: (1)
        Enterprise Value (i.e., market value of equity plus total debt) to
        EBITDA, (2) Enterprise Value to earnings before interest and taxes
        ("EBIT") and (3) Enterprise Value to Revenues. All of these multiples
        were based on trailing-twelve month financials. In addition to
        individual company multiples, SMH calculated the mean (i.e., average),
        and adjusted mean (i.e., average excluding highest and lowest multiples)
        of each ratio.

        EBITDA multiples for the three guideline companies ranged from 12.5x to
        29.5x on September 26, 2000. The adjusted mean multiple for the three
        guideline companies was 21.2x.

        SMH multiplied 21.2 by the division's trailing-twelve month EBITDA of
        $3,115,000, which resulted in an implied enterprise value of
        $66,038,000.

        The next multiple was Enterprise Value/EBIT. EBIT multiples for the
        three public comparables ranged from 19.2x to 540.7x. The adjusted mean
        multiple for the three guideline companies was 46.1x. SMH multiplied
        46.1 by the division's trailing-twelve month EBIT of $1,178,000, which
        resulted in an implied enterprise value of $54,305,800.

        The next multiple was the ratio of Enterprise Value to trailing-twelve
        month Revenues. The three guideline public companies had a range of
        enterprise value/revenue ratios from 1.5x to 13.3x. The adjusted mean
        revenue multiple for the three guideline companies was 9.9x. SMH then
        multiplied 9.9 by the division's trailing-twelve month Revenue of
        $8,187,000, which resulted in an implied enterprise value of
        $81,051,300.

        SMH then averaged the three enterprise values cited above for the
        division to arrive at an average enterprise value of $67,131,700. In
        order to arrive at an implied equity value, SMH subtracted debt and
        added excess cash. As of June 30, 2000, Bowlin had $220,000 in cash and
        $15,426,000 in total debt. This gave the outdoor advertising division an
        implied equity value of $54,925,700 (i.e., $67,131,700 minus $15,426,000
        plus $220,000), or $11.83 per share as of September 26, 2000.

     (7) Comparable Transactions and Premiums.  SMH considered several
         transactions from the past year and a half in the outdoor advertising
         industry, but none were comparable enough to the transaction to make
         their analysis of such transactions more important than the other
         valuation methodologies used. The following table summarizes the
         transactions and price to trailing twelve months EBITDA (prior to
         acquisitions) multiples. Bowlin's outdoor division had trailing twelve
         month ("TTM") EBITDA of $3.1 million as of July 31, 2000, which
         represents a purchase multiple (from $45 million) of 14.7 times. Based
         on the adjusted mean (i.e., excluded highest and lowest multiples)
         price to TTM EBITDA multiple from these transactions of 15.2x compared
         to the price to TTM EBITDA multiple of 14.2x for the outdoor division,
         the multiple Bowlin common stockholders will receive appeared to be
         fair.

</TABLE>

     The preparation of a fairness opinion is a complex process involving
subjective judgments and is not necessarily susceptible to a partial analysis or
summary description. SMH believes that selecting any portion of SMH's analyses,
without considering all analyses, would create a misleading or incomplete view
of the processes underlying the analyses and its opinion. In addition, SMH may
have deemed various assumptions more or less probable than other assumptions, so
that the ranges of valuations resulting for

                                       35
<PAGE>   41

any particular analysis described above should not be taken to be SMH's view of
the actual value of Bowlin, which may be more or less than suggested by the
analyses.

     The analyses performed by SMH are not necessarily indicative of actual
value, which may be significantly more or less favorable than suggested by such
analyses. Such analyses were performed solely as part of SMH's analysis of
whether the consideration to be received pursuant to the Agreement and Plan of
Merger was fair from a financial point of view to Bowlin stockholders, and were
conducted in connection with the delivery of SMH's opinion. The analyses do not
purport to be appraisals or to be indicative of actual values or future results,
or to reflect the prices at which Bowlin or its assets might actually be sold.

     As described above, SMH's opinion provided to the board of directors was
one of a number of factors taken into consideration by the board in making its
determination to recommend adoption of the Agreement and Plan of Merger and the
transaction resulting from it. Consequently, SMH's analyses described above
should not be viewed as determinative of the opinion of the board of directors
or management with respect to the value of Bowlin or its divisions. The Lamar
common stock to be received by the stockholders pursuant to the Agreement and
Plan of Merger was determined through negotiations between representatives of
Bowlin and was approved by the entire board.

     SMH was selected by the board of directors to render a fairness opinion in
connection with the transaction because of SMH's reputation and expertise as an
investment banking firm. SMH, as part of its investment banking business, is
regularly engaged in the valuation of businesses and their securities in
connection with going-private transactions, mergers and acquisitions,
underwritings of equities, private placements and valuations for estate,
corporate and other purposes. In the ordinary course of its business, SMH may
actively trade Bowlin's equity securities for its own account and for the
accounts of customers and, accordingly, may at any time hold a long or
short-term position in such securities.

     In accordance with its engagement letter, the opinion of SMH is addressed
to the board of directors for its use in connection with its review and
evaluation of the proposed transaction. Neither the opinion nor the underlying
SMH analyses may be relied upon by any person other than the members of the
board without the prior written consent of SMH. Accordingly, under the terms of
the engagement letter and the opinion letter prepared pursuant to the engagement
letter, no stockholders of Bowlin may rely or allege any reliance on SMH's
opinion or analysis in connection with the stockholder's consideration of the
merits of the transaction or otherwise. It is SMH's position that its duties in
connection with its fairness opinion are solely to the board of directors, and
that it has no legal responsibility to any other persons, including stockholders
of Bowlin, under the laws of the State of Texas, the governing law of the
engagement letter. SMH would likely assert the substance of this disclaimer as a
defense to claims, if any, that might be brought against it by stockholders of
Bowlin with respect to its fairness opinion. Further, courts interpreting Texas
law have strictly limited the persons who can sue for professional negligence to
the parties to the agreement that provided for the engagement of the
professional. SMH believes that the principles adopted in these cases would
limit its liability solely to the board of directors. However, since no Texas
court has ruled specifically on these issues in the context of SMH's engagement,
they necessarily would have to be resolved by a court of competent jurisdiction.

     Pursuant to the engagement letter agreement between the board of directors
and SMH, dated September 11, 2000, Bowlin agreed to pay SMH (i) a non-refundable
retainer of $25,000 upon execution of the engagement letter and (ii) an
additional $75,000 payable upon submission of SMH's opinion. In addition to any
fees for professional services, SMH will also be reimbursed by Bowlin for
expenses incurred in connection with SMH's assignment. Bowlin has also agreed to
indemnify SMH against specified liabilities, including liabilities under the
federal securities laws, related to, arising out of or in connection with the
engagement of SMH by the board of directors.

POTENTIAL CONFLICTS OF INTEREST OF BOWLIN MANAGEMENT IN THE MERGER

     In considering the merger, you should be aware of the interests executive
officers and directors of Bowlin have in the merger that are different from your
interests and their interests as stockholders. Michael L. Bowlin, Chairman,
President and Chief Executive Officer, beneficially owns approximately 36.8% of
the outstanding common stock. All directors and executive officers as a group
own approximately 58.8% of the outstanding common stock of Bowlin. Directors
have a fiduciary duty to act in the best interest of the stockholders. Officers
have a duty to act in the best interest of the company. However, because the
directors and officers of Bowlin are also stockholders of Bowlin, they might be
inclined to vote to adopt the merger agreement if they believe it is in their
own individual best interests as a stockholder, irrespective of the impact of
that vote on other stockholders. In addition, some directors and officers may
have held options to purchase shares of Bowlin stock at an exercise price that
was less than the current trading price. Although the officers and directors of
Bowlin have not signed any agreements that require them to vote for the merger,
they have indicated their intention to vote in favor of the transaction.

                      THE MERGER AND THE MERGER AGREEMENT

     The following is a summary of significant provisions of the merger
agreement. For a more complete understanding of the merger agreement, you should
read the agreement. The agreement is attached as Annex A and is incorporated
into this proxy statement/prospectus by reference.

GENERAL DESCRIPTION OF THE MERGER

     In the merger, Lamar Southwest Acquisition Corporation, a newly formed,
wholly owned subsidiary of Lamar, will merge with and into Bowlin. Bowlin will
be the surviving corporation and will continue to exist under Nevada law as a
wholly owned subsidiary of Lamar. The articles of incorporation of Bowlin, which
will be amended and restated and filed with the articles of merger, will be the
articles of incorporation of the surviving corporation. The by-laws of Lamar
Southwest, as in effect immediately before the merger, will be the by-laws of
the surviving corporation.

     Bowlin and its subsidiary, Bowlin Travel Centers, Inc., entered into a
contribution agreement dated as of November 1, 2000 in the form attached as
Annex B to this proxy statement/prospectus. This contribution agreement provides
that certain assets and liabilities of Bowlin related to Bowlin's travel centers
line of business will be contributed to Bowlin Travel. Bowlin intends to
distribute the shares of Bowlin Travel to the Bowlin stockholders immediately
prior to the completion of the merger. The business, assets and liabilities of
the travel center's line of business, therefore, will not be acquired by Lamar
in the merger.

  Contribution Agreement

     Under the contribution agreement, Bowlin contributed all of the assets and
liabilities directly associated with the ownership and operation of the travel
centers business to Bowlin Travel Centers, Inc. Bowlin and Bowlin Travel each
represented that it was duly organized, had the authority to enter into the
agreement, and that there were no conflicts or violations resulting from, or
consents required by, the execution and delivery of the agreement. Bowlin Travel
also covenants under the agreement to offer employment to all of the employees
of Bowlin that work in the travel centers business, on the same terms and
conditions of employment they currently enjoy with Bowlin, and to assume all
obligations and liabilities associated with those employees. Under the
agreement, Bowlin Travel agreed to indemnify Bowlin, its directors, officers,
shareholders, employees, affiliates, successors and assigns for any and all
losses, liabilities, claims, demands, penalties, fines, settlements, damages, or
expenses (including, without limitation, interest, penalties, costs of
preparation and investigation, and the reasonable fees, disbursements and
expenses of attorneys, accountants and professional advisors) incurred by any of
the Bowlin indemnitees:

     - arising under federal, state or local environmental laws and arising out
       of or in connection with the travel center business or the ownership or
       operation of any of the assets or assumed liabilities;

     - resulting from any labor or employment dispute arising out of or in
       connection with the operation of the travel center business or otherwise
       involving a travel centers business employee; and

     - any attempt (whether or not successful) by any person to cause or require
       Bowlin to discharge or pay any assumed liability, or otherwise arising
       out of or relating to any assumed liability.

  Tax Sharing and Disaffiliation Agreement

     As part of the Contribution Agreement, Bowlin and Bowlin Travel entered
into a Tax Sharing and Disaffiliation Agreement, which we refer to as the Tax
Agreement. The Tax Agreement sets forth rights and obligations of Bowlin and
Bowlin Travel with respect to taxes imposed on their respective businesses both
before and after the distribution of Bowlin Travel shares to the Bowlin
shareholders and with respect to "Restructuring Taxes." For purposes of the Tax
Agreement, "Restructuring Taxes" are taxes imposed in connection with the
contribution by Bowlin of the travel centers-related assets and liabilities to
Bowlin Travel and the distribution.

                                       38
<PAGE>   44

     General Taxes.  Under the Tax Agreement, Bowlin Travel will be liable for
and indemnify Bowlin against any taxes that are attributable to the travel
centers business (both before and after transfer of such business to Bowlin
Travel), Restructuring Taxes and sales, transfer and other similar taxes
incurred in connection with the contribution and distribution. Bowlin will be
liable for and indemnify Bowlin Travel against any taxes that are attributable
to the outdoor advertising business. The Tax Agreement sets forth additional
rules for determining the tax obligations of Bowlin and Bowlin Travel.

     Restructuring Taxes.  Under the Tax Agreement, Bowlin Travel is generally
responsible for all Restructuring Taxes. Bowlin and Bowlin Travel anticipate
that the contribution will not result in any tax liability and that the
distribution will not result in any tax liability to Bowlin shareholders.
However, Bowlin may be liable for Restructuring Taxes in connection with the
distribution. More specifically, Bowlin will be required to pay tax on gain (if
any) equal to the value of Bowlin Travel on the date of the distribution, less
Bowlin's basis in Bowlin Travel shares immediately before the distribution.
Bowlin and Bowlin Travel plan to base the value of Bowlin Travel on the
first-day trading price of Bowlin Travel shares. Therefore, the amount of this
gain and any consequent Restructuring Taxes will not be determined until the
time of the distribution. Depending upon the value of Bowlin Travel as of the
distribution, the amount of Restructuring Taxes could be substantial. In
addition, it is possible that the IRS may successfully challenge any valuation
of Bowlin Travel for this purpose and thereby assess additional Restructuring
Taxes. As stated previously, under the Tax Agreement, Bowlin Travel is required
to reimburse Bowlin for any Restructuring Taxes.

     Administrative Matters.  The Tax Agreement also sets forth the obligations
of Bowlin and Bowlin Travel with respect to the filing of tax returns, the
administration of tax contests and other matters.

  Reasons for the Distribution

     The distribution of the Bowlin Travel stock is being carried out for the
purpose of facilitating the tax-free acquisition of Bowlin by Lamar because
Lamar is not interested in acquiring the travel center business.

EFFECTIVE TIME

     We expect to close the merger during the first quarter of 2001. The merger
will be effective upon the filing of articles of merger with the Nevada
Secretary of State, or a later time that we specify in the articles of merger.
We plan to file the articles of merger soon after the Bowlin special meeting.

MERGER CONSIDERATION FOR BOWLIN STOCK AND EXCHANGE RATIO

     At the effective time of the merger, each share of Bowlin stock will be
converted into the right to receive Lamar stock equal to the product of (A) one
share of Lamar stock and (B) the quotient of (x) 725,000, divided by (y) the
total number of shares of Bowlin stock issued and outstanding. Assuming that all
outstanding Bowlin stock options are exercised prior to the closing of the
merger, there would be 4,583,348 shares of Bowlin stock outstanding and the
exchange ratio would be .15818. Cash will be paid for any fractional shares. In
no event will Lamar issue more than 725,000 shares of Lamar stock for the
outstanding shares of Bowlin stock. The exchange formula was agreed to in
arm's-length negotiations between representatives of Lamar and Bowlin.

     The 725,000 shares of Lamar stock issuable in the merger represent
approximately .91% of the total Lamar stock that will be outstanding after the
issuance.

NO FRACTIONAL SHARES

     Lamar will not issue fractional shares in the merger. Instead, Lamar will
pay cash to each Bowlin stockholder who otherwise would be entitled to receive a
fractional share of Lamar stock. The cash amount will equal the fractional share
number multiplied by the average of the closing sales prices of a

                                       39
<PAGE>   45

share of Lamar stock as reported on the Nasdaq National Market System for the 30
trading days ending on the last trading day immediately prior to the closing of
the merger.

EXCHANGE OF BOWLIN STOCK CERTIFICATES

     Promptly after the effective time, the exchange agent will mail transmittal
forms to each person who held shares of Bowlin stock as of the effective time
for use in exchanging Bowlin stock certificates for Lamar stock certificates and
any cash for fractional shares. The transmittal forms will include instructions
specifying details of the exchange.

     DO NOT SEND IN YOUR BOWLIN CERTIFICATES UNTIL YOU RECEIVE A TRANSMITTAL
FORM.

     If certificates for any shares of Bowlin stock have been lost, stolen or
destroyed, the holder must submit appropriate evidence regarding the ownership,
loss, theft or destruction of the certificate, an affidavit to that effect and a
customary indemnification agreement to the exchange agent.

     Lamar will honor a request from a person surrendering a Bowlin stock
certificate that the Lamar stock being given in exchange be issued to a person
other than the registered holder of the certificate on the exchange agent's
books, so long as the requesting person:

     - submits all documents necessary to evidence and effect the transfer to
       the new holder; and

     - pays any transfer or other taxes for issuing shares of Lamar stock to a
       person other than the registered holder of the certificate, unless the
       requesting person satisfactorily establishes to Lamar that any tax has
       been paid or is inapplicable.

     Holders of Bowlin stock exchanged for Lamar stock in the merger will be
entitled to receive dividends and other distributions on Lamar stock (without
interest) that are declared or made with a record date after the effective time.
Dividends or other distributions will not be paid to any former holder of Bowlin
stock, however, until that holder surrenders its shares of Bowlin stock to the
exchange agent.

TREATMENT OF BOWLIN STOCK OPTIONS

     Any options for Bowlin stock that were issued to directors or employees
under Bowlin's option plans that had not been exercised by November 17, 2000
were cancelled and no longer represent the right to receive Bowlin stock or
Lamar stock. On October 17, 2000, Bowlin notified each holder of an option to
purchase Bowlin stock, except HD Brous & Co., Inc., that they had the right to
exercise any and all options to purchase Bowlin stock, whether or not currently
exercisable according to their respective terms, prior to November 17, 2000. A
total of 244,500 of these options were not exercised by November 17, 2000 and
have been automatically terminated. The only options currently outstanding are
options to purchase 10,000 shares of Bowlin stock at an exercise price of $5.00
per share, held by HD Brous & Co., Inc. These options will expire on the earlier
to occur of (i) 5:00 p.m. Arizona time on the business day immediately prior to
the date on which the merger is effectuated, or (ii) 5:00 p.m. Arizona time on
December 31, 2000.

TREATMENT OF BOWLIN BENEFITS

     The Bowlin employees who remain employees of the surviving corporation will
be eligible to participate in Lamar's 401(k) plan and any assets that they have
in the Bowlin plan will be transferred to Lamar's plan. After the spin-off of
Bowlin Travel, Bowlin Travel will continue to maintain the Bowlin 401(k) plan as
a successor employer to those employees who do not remain with the surviving
corporation following the merger.

                                       40
<PAGE>   46

ACCOUNTING TREATMENT

     Lamar will account for the merger using the purchase method of accounting
for a business combination. Under this method of accounting, the assets and
liabilities of Bowlin, including intangible assets, will be recorded at their
fair market values. The results of operations and cash flows of Bowlin will be
included in Lamar's financial statements following the completion of the merger.

MATERIAL UNITED STATES FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER

     The following discussion summarizes the material U.S. federal income tax
consequences of the merger. The discussion is based on the Internal Revenue
Code, related regulations, existing administrative interpretations and court
decisions, all of which may change, possibly with retroactive effect. This
discussion assumes that Bowlin stockholders hold their shares of Bowlin stock as
capital assets within the meaning of Section 1221 of the Internal Revenue Code.
This discussion does not address all aspects of U.S. federal income taxation
that may be important to you either in light of your particular circumstances or
if you are subject to special rules. These special rules include those relating
to:

     - stockholders who are not U.S. citizens or residents or that are foreign
       corporations, partnerships, estates or trusts;

     - financial institutions;

     - tax-exempt organizations;

     - insurance companies;

     - dealers in securities;

     - stockholders who acquired their Bowlin stock by exercising options or
       similar derivative securities or otherwise as compensation; and

     - stockholders who hold their Bowlin stock as part of a hedge, straddle,
       appreciated financial position or conversion transaction.

     This section, as it relates to matters of United States federal income tax
law, constitutes the opinion of Squire, Sanders & Dempsey L.L.P., counsel to
Bowlin. These opinions are based on a number of assumptions, representations and
covenants, including the assumption that the merger will be completed as
described in this document. The opinions neither bind the IRS nor preclude the
IRS from adopting a position contrary to that expressed in the opinions. Bowlin
and Lamar cannot assure you that contrary positions will not be successfully
asserted by the IRS or adopted by a court if the issues are litigated. Neither
of us intends to obtain a ruling from the IRS with respect to the tax
consequences of the merger.

  Tax Consequences to Bowlin Stockholders

     Except as discussed below, Bowlin stockholders will not recognize gain or
loss for U.S. federal income tax purposes on the exchange of Bowlin stock for
Lamar stock in the merger. The aggregate tax basis of Lamar stock received in
the merger will be the same as the aggregate tax basis of the Bowlin stock
surrendered in exchange therefor, reduced by the portion of the tax basis of the
Bowlin stock allocable to fractional shares of Lamar stock for which cash is
received instead. The holding period of Lamar stock received as a result of the
exchange will include the holding period of the Bowlin stock surrendered in
exchange. Bowlin stockholders will recognize gain or loss for U.S. federal
income tax purposes on the cash they receive in place of fractional shares of
Lamar stock. The gain or loss will be measured by the difference between the
amount of cash received and the portion of the tax basis of the Bowlin stock
surrendered in the merger that is allocable to those fractional shares of Lamar
stock.

  Tax Consequences to Lamar and Bowlin

     Lamar, including its merger subsidiary, and Bowlin will not recognize gain
or loss for U.S. federal income tax purposes by reason of the merger. However,
Bowlin may be liable for taxes imposed in connection with the contribution by
Bowlin of the travel centers-related assets and liabilities to Bowlin Travel and
the distribution. More specifically, Bowlin will be required to pay tax on the
gain (if any) equal to the value of Bowlin Travel on the date of the
distribution, less Bowlin's basis in the Bowlin Travel shares immediately before
the distribution. Bowlin Travel has agreed to indemnify Bowlin for these taxes.
See "General Description of the Merger -- Tax Sharing and Disaffiliation
Agreement."

  Backup Withholding

     Unless a stockholder complies with reporting and/or certification
procedures or is an exempt recipient under the backup withholding and
information reporting provisions of the Internal Revenue Code and Treasury
regulations, the holder may be subject to a 31% backup withholding tax on any
cash payments received in the merger. Any amounts withheld under the backup
withholding rules may be allowed as a refund or a credit against the holder's
federal income tax liability, provided the required information is furnished to
the IRS.

     THE FOREGOING DISCUSSION IS ONLY INTENDED TO PROVIDE YOU WITH A GENERAL
SUMMARY. IT IS NOT A COMPLETE ANALYSIS OR DESCRIPTION OF EVERY POTENTIAL U.S.
FEDERAL INCOME TAX CONSEQUENCE OR ANY OTHER CONSEQUENCE OF THE MERGER. IN
ADDITION, THE DISCUSSION DOES NOT ADDRESS TAX CONSEQUENCES THAT MAY VARY WITH,
OR ARE CONTINGENT ON, YOUR INDIVIDUAL CIRCUMSTANCES. MOREOVER, THIS DISCUSSION
DOES NOT ADDRESS ANY NON-INCOME TAX OR ANY FOREIGN, STATE OR LOCAL TAX
CONSEQUENCES OF THE MERGER. ACCORDINGLY, WE STRONGLY URGE YOU TO CONSULT WITH
YOUR TAX ADVISOR TO DETERMINE THE PARTICULAR U.S. FEDERAL, STATE, LOCAL OR
FOREIGN TAX CONSEQUENCES TO YOU OF THE MERGER.

      -- if there is a non-appealable government order prohibiting the
         consummation of the merger; or

      -- if the Bowlin stockholders fail to approve the merger, unless the

                                       46
<PAGE>   52

AMENDMENTS AND WAIVERS

     Generally, Lamar and Bowlin may amend or waive any provision of the merger
agreement before the effective time of the merger. However, if a material
condition is waived, Lamar will amend the registration statement of which this
proxy statement/prospectus forms a part, and Bowlin will resolicit proxies for
the adoption of the merger agreement. In addition, after Bowlin stockholders
have approved the merger, their further approval would be required to modify the
amount or type of consideration that they will receive in the merger, to alter
the charter of the surviving corporation or to otherwise alter the merger
agreement in a manner materially adverse to them.

APPRAISAL OR DISSENTERS' RIGHTS

     Under Nevada law, Bowlin stockholders are not entitled to appraisal or
dissenters' rights in connection with the merger because:

     - Bowlin stock was, as of the record date for the special meeting,
       designated and reported for trading on the American Stock Exchange; and

     - Bowlin stock will be converted into shares of Lamar stock, which will be
       designated and reported for trading on the Nasdaq National Market.

NASDAQ LISTING OF LAMAR STOCK

     Lamar has agreed to file a listing notification with Nasdaq concerning the
Lamar stock to be issued to Bowlin stockholders in the merger.

DELISTING OF BOWLIN STOCK

     If the merger is completed, Bowlin stock will cease to be quoted on the
American Stock Exchange.

NO LISTING OF BOWLIN TRAVEL STOCK

     Bowlin Travel does not intend to apply for the listing of its stock on any
securities exchange.

RESALES OF LAMAR STOCK BY BOWLIN AFFILIATES

     Bowlin stockholders may freely transfer the shares of Lamar stock received
in the merger, unless they are individuals and entities who are deemed to be
"affiliates" of Bowlin before the merger or affiliates of Lamar after the
merger. Persons who may be deemed to be affiliates of Bowlin or Lamar include
individuals or entities that control, are controlled by, or are under common
control with Bowlin or Lamar and may include executive officers and directors as
well as principal stockholders. These affiliates or their brokers may be
characterized as "underwriters" when they sell shares of Lamar stock received in
the merger. The United States securities laws require registration of shares
sold by underwriters. An affiliate and its broker can avoid being characterized
as an underwriter and, therefore, avoid the Securities Act registration
requirements by selling shares in compliance with Rule 145 or Rule 144 under the
Securities Act. Rule 145 covers sales by Bowlin affiliates, and Rule 144 covers
sales by Lamar affiliates. Each rule limits the number of shares an affiliate
can sell in a particular period of time. The merger agreement requires Bowlin to
use its best efforts to cause each of its affiliates to execute and deliver to
Lamar a written agreement to the effect that the affiliate will not offer or
sell or otherwise dispose of Lamar stock issued to the affiliate in the merger
in violation of the Securities Act or the related rules and regulations adopted
by the SEC. The receipt of these "affiliate letters" is a condition to Lamar's
obligation to close the merger.

     This proxy statement/prospectus does not cover resales of Lamar stock
received by any person who may be deemed to be an affiliate of Bowlin and/or
Lamar.

REGULATORY MATTERS

     Under the Hart-Scott-Rodino Antitrust Improvements Act and related rules,
this merger may not be completed unless information and materials about the
companies and the merger are furnished to the Antitrust Division of the
Department of Justice and the Federal Trade Commission and the appropriate
waiting period requirements have been satisfied. Lamar and Bowlin have made the
required filings with both agencies and the required waiting period has expired.
At any time before or after the completion of the merger, however, the
Department of Justice, the Federal Trade Commission or others could take action
under the antitrust laws, including seeking to prevent the merger, to rescind
the merger or to conditionally approve the merger upon the divestiture of
substantial assets of Lamar or Bowlin. Lamar and Bowlin cannot guarantee that a
challenge to the merger on antitrust grounds will not be made or, if a challenge
is made, that it would not be successful.

     Lamar and Bowlin are not aware of any other material governmental or
regulatory requirements that must be complied with regarding the merger, other
than federal securities laws and the filing of documents describing principal
terms of the merger agreement with the secretary of state of Nevada.

     The "Percent of Class" column below is based on 75,392,608 shares of Lamar

deems shares of Lamar stock subject to options that are currently exercisable or
exercisable within 60 days of October 31, 2000, to be outstanding and to be
beneficially owned by the person holding the options for the purpose of
computing the percentage ownership of the person, but does not treat them as
outstanding for the purpose of computing the percentage ownership of any other
person.

     The following table and footnotes set forth certain information regarding
the beneficial ownership of Lamar stock as of October 31, 2000 by (i) persons
known by Lamar to be beneficial owners of more than 5% of either class of common

 (1) The persons and entities named in the table have sole voting and investment
     power with respect to all shares beneficially owned by them, except as
     noted below.

 (2) Upon the sale of any shares of Class B common stock to a person other than
     to a permitted transferee, such shares will automatically convert into
     shares of Class A common stock. Permitted transferees include (i) Kevin P.
     Reilly, Sr.; (ii) a descendant of Kevin P. Reilly, Sr.; (iii) a spouse or
     surviving spouse (even if remarried) of any individual named or described
     in (i)or (ii) above; (iv) any estate, trust, guardianship, custodianship,
     curatorship or other fiduciary arrangement for the primary benefit of any
     one or more of the individuals named or described in (i), (ii) and (iii)

                      FUTURE BOWLIN STOCKHOLDER PROPOSALS

     If the stockholders of Bowlin do not approve the merger agreement or if the
merger is not consummated, Bowlin anticipates holding its next annual meeting of
stockholders as soon as practicable following the special meeting. Stockholder
proposals to be presented at that meeting should be submitted by December 31,
2000, in order to be considered for inclusion in the proxy materials for that
meeting.

                                 OTHER MATTERS

     Bowlin has separated its travel centers business from its outdoor
advertising business. Bowlin contributed its existing travel center business to
Bowlin Travel Centers, Inc., a newly formed subsidiary. Prior to consummation of
the merger, Bowlin intends to distribute all of the capital stock of Bowlin
Travel held by Bowlin to the Bowlin stockholders on a pro rata basis.
Accordingly, each holder of Bowlin's common stock as of the record date would
receive one share of the common stock of Bowlin Travel for each share of the
common stock of Bowlin they own on that date. The record date for the
distribution has not yet been determined. This spin-off must occur prior to the
merger of Bowlin with Lamar. It is anticipated that the stock of Bowlin Travel
will be distributed to stockholders of Bowlin immediately prior to the closing
of the merger with Lamar.

     Neither Lamar nor Bowlin presently intends to bring before the Bowlin
special meeting any matters other than those specified in the notice and
accompanying this proxy statement/prospectus, and neither Lamar nor Bowlin has
any knowledge of any other matters that may be brought up by other persons.
However, if any other matters come before the Bowlin special meeting or any
adjournments of the meeting, the persons named in the enclosed proxy, including
any substitutes, will use their best judgment to vote the proxies.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                  (UNAUDITED)

     1. The consolidated financial statements for the three and six months ended
July 31, 2000 and 1999 are unaudited and reflect all adjustments (consisting
only of normal recurring adjustments) which are, in the opinion of management,
necessary for a fair presentation of the financial position and operating
results for the interim periods. The consolidated financial statements should be
read in conjunction with the consolidated financial statements and notes,
together with management's discussion and analysis of financial condition and
results of operations, contained in Bowlin's annual report on Form 10-K for the
fiscal year ended January 31, 2000. Results of operations for interim periods
are not necessarily indicative of results that may be expected for the year as a
whole.

     2. In May 2000, Bowlin sold certain assets, including land and equipment,
to a third party for $25,000 cash and a note receivable for $400,000. The note
receivable has a stated rate of interest of 8 percent and is payable in annual
installments of $37,500 through 2004 with the balance due in 2005. The assets
sold had a carrying value of $170,258 and the costs incurred to sell the assets
was $6,043. The gain on the sale of the property was $248,699, of which $14,625
was recognized initially and $234,074 was deferred and will be recognized into
income using the installment method as payments are received. The deferred gain
is reflected as a reduction to the note receivable in the accompanying balance
sheet.

     3. Earnings per Share. The following table is a reconciliation of the
numerators and denominators of the basic and diluted per share computations for
income from continuing operations.

     4. Segment Information: Travel center operations, which represents 77
percent of net sales of Bowlin, and outdoor advertising operations, which
represents 23 percent of net sales, are Bowlin's reportable segments under SFAS
No. 131, Disclosure about Segments of an Enterprise and Related Information. The
travel center segment provides for the retail sale of merchandise, food and
gasoline to the traveling public while the outdoor advertising segment operates
billboard advertising displays which are situated on interstate highways,
primarily in the Southwestern United States. No single customer accounted for 10
percent of consolidated net sales in any period.

     Effective February 1, 2000, Bowlin measures its segments' results of
operations (segment profit) based on operating income less allocable interest
expense. Accordingly, segment profit for all periods presented has been
retroactively restated to conform to the new presentation. The accounting
policies used to measure segment results of operations are the same as those
described in note 1 to the consolidated financial statements included in Form
10-K for the year ended January 31, 2000.

(1) Corporate and other results of operations include costs associated with
    certain members of executive management, the corporate accounting and
    finance function and other typical administrative functions not considered
    in assessing segment profit.

(2) There were no inter-segment sales.

(3) Management does not consider interest income, non-operating income and
    expense amounts or income tax expense in the determination of the operating
    performance of the reportable segments. However, the amount reported for
    corporate and other includes interest income and non-operating income and
    expense. The total segment profit agrees to income before income taxes in
    the consolidated statements of income.

     THIS AGREEMENT AND PLAN OF MERGER (this "Agreement"), dated October 3,

removal, or until their respective successors are duly elected or appointed and
qualified, as the case may be.

                                   ARTICLE 2

                       EFFECT ON THE CAPITAL STOCK OF THE
               CONSTITUENT CORPORATIONS; EXCHANGE OF CERTIFICATES

     2.1  Effect on Capital Stock. At the Effective Time, by virtue of the
Merger and without any further action on the part of Lamar, NewCo, Bowlin or the
stockholders of such entities:

          (1) Capital Stock of NewCo. Each issued and outstanding share of
     capital stock of NewCo will be converted into and become one fully paid and
     nonassessable share of common stock of the Surviving Corporation.

          (2) Cancellation of Bowlin Treasury Stock. Each share of Bowlin
     capital stock that is held in treasury by Bowlin (or by any Bowlin
     subsidiary) shall be canceled and no Lamar Common Stock or other
     consideration will be delivered in exchange therefor.

          (3) Conversion of Bowlin Common Stock.

             (1) Subject to Sections 2.1(b) and 2.1(c)(ii), each share of Bowlin
        Common Stock issued and outstanding immediately prior to the Effective
        Time (including shares of Bowlin Common Stock issued upon the exercise
        of options prior to the Effective Time but excluding treasury shares
        cancelled pursuant to Section 2.1(b)) will be converted into the right
        to receive a number of validly issued, fully paid and nonassessable
        shares of Lamar Common Stock equal to the product of (A) one share of
        Lamar Common Stock and (B) the quotient of (x) 725,000, divided by (y) a
        number equal to the total number of shares of Bowlin Common Stock issued
        and outstanding at the Effective Time (including shares of Bowlin Common
        Stock issued upon the exercise of options prior to the Effective Time
        but excluding treasury shares cancelled
                                       A-2
<PAGE>   81

        pursuant to Section 2.1(b)). In no event will Lamar be required to issue
        in connection with the Merger more than 725,000 shares of Lamar Common
        Stock (the "Merger Shares") (except to reflect adjustment for any stock
        splits, combinations or recapitalizations relating to Lamar Common Stock
        effected by Lamar after the date of this Agreement).

             (2) No certificates or scrip representing fractional shares of
        Lamar Common Stock will be issued upon conversion of the shares of
        Bowlin Common Stock, and fractional share interests will not entitle the
        owners of the fractional interests to vote or to any rights of a holder
        of Lamar Common Stock. Any holder of Bowlin Common Stock who would
        otherwise be entitled to receive a fraction of a share of Lamar Common
        Stock (after aggregating all fractional shares issuable to such holder)
        shall, in lieu of such fraction of a share, be entitled to receive an
        amount in cash, without interest and rounded to the nearest cent, equal
        to the product of (A) such fraction and (B) the Average Closing Share
        Price. Payments for fractional shares will be made at the time the
        Merger Shares are delivered to the Bowlin stockholders pursuant to
        Section 2.2.

     2.2  Exchange of Stock Certificates; Record Date.

     (1) Prior to the Effective Time, Lamar will appoint the American Stock
Transfer & Trust Company or another entity (the "Exchange Agent") to arrange for
the exchange of certificates that, immediately prior to the Effective Time,
represented issued and outstanding shares of Bowlin Common Stock (the "Bowlin
Certificates") for the Merger Shares. On or before the Closing Date, Lamar will
deliver to the Exchange Agent, in trust for the benefit of each holder of record
of Bowlin Common Stock, (x) stock certificates representing all of the shares of
Lamar Common Stock issuable pursuant to Section 2.1(c)(i), and (y) sufficient
funds to make cash payments in lieu of fractional Merger Shares pursuant to
Section 2.1(c)(ii). As soon as practicable after the Effective Time, Lamar will
cause the Exchange Agent to mail a notice and letter of transmittal to each
recordholder of Bowlin Common Stock advising such recordholder of the
effectiveness of the Merger and providing instructions for surrendering to the
Exchange Agent the Bowlin Certificates representing Bowlin Common Stock in
exchange for the Merger Shares and any cash payment in lieu of fractional Merger
Shares. Each holder of Bowlin Certificates, upon proper surrender thereof and a
duly completed letter of transmittal to the Exchange Agent, will be entitled to
receive from the Exchange Agent in exchange for the Bowlin Certificates (subject
to any taxes required to be withheld) the number of Merger Shares determined in
accordance with Section 2.1(c). Until properly surrendered, after the Effective
Time each Bowlin Certificate will be deemed for all purposes to evidence only
the right to receive Merger Shares and any cash payment in lieu of fractional
shares. Holders of Bowlin Certificates will not be entitled to receive
certificates representing Merger Shares or any cash payment in lieu of
fractional shares until their Bowlin Certificates are properly surrendered.

     (b) If any Bowlin Certificate has been lost, stolen or destroyed, upon the
making of an affidavit of that fact by the Person claiming the Bowlin
Certificate to be lost, stolen or destroyed (a "Missing Certificate"), Lamar
will direct the Exchange Agent to issue in exchange for the shares of Bowlin
Common Stock represented by the Missing Certificate, the Merger Shares issuable
pursuant to Section 2.1(c) and any cash payment in lieu of fractional shares.
The Board of Directors of Lamar may, in its discretion and as a condition to the
issuance of any Merger Shares or cash payment in lieu of fractional shares to
the owner of shares of Bowlin Common Stock represented by a Missing Certificate,
require the owner to provide Lamar with an affidavit and a bond in a sum as
Lamar may reasonably direct as an indemnity against any claim that may be made
against Lamar or the Exchange Agent with respect to the Missing Certificate.

     2.3  No Further Rights in Bowlin Common Stock.  As of the Effective Time,
all shares of Bowlin Common Stock will no longer be outstanding and will
automatically be canceled and retired and will cease to exist, and each holder
of a Bowlin Certificate representing shares of Bowlin Common Stock as of the
Effective Time will cease to have any rights with respect to the Bowlin Common
Stock, except the right to receive Merger Shares and any cash payment in lieu of
fractional shares as provided in this Agreement.

                                       A-3
<PAGE>   82

     2.4  Distributions with Respect to Unexchanged Shares.  No dividends or
other distributions declared on or after the Effective Time with respect to
shares of Lamar Common Stock will be paid to any Bowlin stockholder with respect
to any Merger Shares that such Bowlin stockholder has the right to receive in
the Merger until the stockholder has properly surrendered shares of Bowlin
Common Stock in exchange for Lamar Common Stock (and any fractional payment) in
accordance with this Article 2. Subject to Applicable Law, following the proper
surrender of any Bowlin Certificate by a Bowlin stockholder and delivery to such
stockholder of a certificate representing whole shares of Lamar Common Stock,
Lamar will pay to such stockholder, without interest, the amount of any
dividends or other distributions declared by Lamar on or after the Effective
Time.

     2.5  Undelivered Merger Consideration.  Any certificates representing
shares of Lamar Common Stock or cash that remain undistributed by the Exchange
Agent to former holders of Bowlin Common Stock as of the date that is one year
after the Effective Date shall be returned by the Exchange Agent to Lamar upon
demand, and any holder of Bowlin Certificates who has not theretofore
surrendered his or her shares of Bowlin Common Stock in accordance with Section
2.2 shall thereafter look only to Lamar for satisfaction of his or her claims
for Lamar Common Stock, cash in lieu of fractional shares of Lamar Common Stock
and any dividends or distributions with respect to Lamar Common Stock.

     2.6  Escheat.  Neither Lamar nor the Surviving Corporation shall be liable
to any holder or former holder of Bowlin Common Stock or to any other Person
with respect to any shares of Lamar Common Stock (or dividends or distributions
with respect thereto), or for any cash amounts, delivered to any public official
pursuant to any applicable abandoned property law, escheat law, or similar legal
requirement.

                                   ARTICLE 3

                    REPRESENTATIONS AND WARRANTIES OF BOWLIN

interest, joint venture interest or other equity interest in any Person. All

to do business and is in good standing in each jurisdiction in which the

exclusively of 100,000,000 shares of common stock, $.001 par value per share, of
which as of September 29, 2000, 4,390,098 shares were outstanding and no shares
were held in treasury. All of the issued and outstanding shares of Bowlin have
been validly issued, are fully paid and nonassessable and are free of preemptive
rights. As of September 29, 2000, (a) 429,750 shares of Bowlin Common Stock were
reserved for issuance pursuant to the exercise of stock options granted and
outstanding under the stock option plan designated Bowlin's Incorporated 1996
Stock Option Plan (the "Option Plan"), which is the only stock option plan
adopted by Bowlin pursuant to which stock options have been or may be granted,
(b) 10,000 shares of Bowlin Common Stock were reserved for issuance to H.D.
Brous & Co., Inc. pursuant to options granted on September 19, 2000 (the options
referred to under (a) and (b), are referred to individually as a "Bowlin Option,
and collectively, as the "Bowlin Options"). Schedule 3.2 sets forth the
following

                                       A-4

information with respect to the Bowlin Options outstanding as of September 29,
2000: (i) the name of the optionee for each outstanding Bowlin Option; (ii) the
number of shares of Bowlin Common Stock subject to such Bowlin Option; and (iii)

     (1) Bowlin will take all action necessary under law to call, give notice of

adopt this Agreement. The Bowlin Stockholders Meeting shall be held (on a date
selected by Bowlin in consultation with Lamar) as promptly as practicable after
the Registration Statement is declared effective under the Securities Act.

     (2) Subject to Section 5.2(c), (i) the Proxy Statement/Prospectus shall

the Board Recommendation may be withdrawn or modified in a manner adverse to
Lamar if: (i) a proposal to acquire (by merger or otherwise) all of the
outstanding shares of Bowlin Common Stock is made to Bowlin and is not
withdrawn; (ii) Bowlin's Board of Directors determines in good faith (based upon
a written opinion of an independent financial advisor of nationally recognized
reputation) that such offer constitutes a Superior Proposal; (iii) Bowlin's
Board of Directors determines in good faith, after having taken into account the
written advice of Bowlin's outside legal counsel, that, in light of such
Superior Proposal, the withdrawal or modification of the Board Recommendation is
required in order for Bowlin's Board of Directors to comply with its fiduciary
obligations to Bowlin's stockholders under applicable law; and (iv) neither
Bowlin nor any of its Representatives shall have violated any of the
restrictions set forth in Section 5.5.

promptly respond to any SEC comments on the Proxy Statement/ Prospectus or
Registration Statement and each of Lamar and Bowlin will use its commercially
reasonable efforts to resolve all SEC comments as promptly as practicable to the
satisfaction of the SEC and to have the Registration Statement declared

jurisdiction in which it is now not so qualified) required to be taken under any
applicable state securities laws in connection with the issuance of the Lamar

all of its assets other than those consumed or disposed of for value in the

encourage, induce or otherwise facilitate the initiation or submission of any
inquiries, proposals or offers that constitute or may reasonably be expected to
lead to an Acquisition Proposal (as defined below), (ii) furnish any information

furnishing nonpublic information regarding any member of the Bowlin Group to, or
entering into discussions with, any Person in response to a Superior Proposal
that is submitted to Bowlin by such Person (and not withdrawn) if (w) neither
Bowlin nor any Bowlin Representative shall have violated any of the restrictions
set forth in this Section 5.5, (x) the Board of Directors of Bowlin concludes in
good faith, after having taken into account the written advise of its outside
legal counsel, that such action is required in order for the Board of Directors
of Bowlin to comply with its fiduciary obligations to Bowlin's stockholders
under applicable law, (y) at or prior to furnishing any such nonpublic
information to, or entering into discussions with, such Person, Bowlin gives

                                      A-20
<PAGE>   99

furnish nonpublic information to, or enter into discussions with, such Person,
and Bowlin receives from such Person an executed confidentiality agreement
containing provisions no less favorable to Bowlin than those contained in the
Confidentiality Agreement (as defined below) between Bowlin and Lamar, and (z)
at or prior to furnishing any such nonpublic information to such Person, Bowlin
furnishes such nonpublic information to Lamar (to the extent such nonpublic
information has not been previously furnished by Bowlin to Lamar). Without
limiting the generality of the foregoing, Bowlin acknowledges and agrees that
any violation of or the taking of any action inconsistent with any of the
restrictions set forth in the preceding sentence by any Bowlin Representative,
whether or not such Bowlin Representative is purporting to act on behalf of
Bowlin, shall be deemed to constitute a breach of this Section 5.5 by Bowlin.

     (2) For purposes of this Agreement, "Acquisition Proposal" means a proposal
for any of the following (other than the transactions contemplated by this

Bowlin Group except Bowlin Travel: (A) any merger, reorganization,
consolidation, share exchange, recapitalization, business combination,
liquidation, dissolution, or other similar transaction involving, or, any sale,
lease, exchange, mortgage, pledge, transfer or other disposition of, all or any
significant portion of the assets or 10% or more of the equity securities of,
any member of the Bowlin Group; (B) any tender offer or exchange offer for 20%
or more of the outstanding shares of capital stock of Bowlin or the filing of a

any public announcement of a proposal, plan or intention to do any of the
foregoing or any agreement to engage in any of the foregoing.

     (3) For purposes of this Agreement, "Superior Proposal" means a bona fide
proposal made by a third party to acquire Bowlin pursuant to an Acquisition
Proposal that the Board of Directors of Bowlin determines in its good faith
judgment (after considering the written advice of Bowlin's independent advisors)
to merit the withdrawal of the Board Recommendation because such third party
proposal has more favorable economic terms than the transactions contemplated by
this Agreement.

     (4) Bowlin will immediately notify Lamar after receipt of any Acquisition
Proposal or any request for nonpublic information relating to any member of the
Bowlin Group in connection with an Acquisition Proposal or for access to any of
the premises, books or records of any member of the Bowlin Group by any person
or entity that informs Bowlin or its Board of Directors, formally or informally,
that it is considering making, or has made, an Acquisition Proposal. Such notice
to Lamar will be made orally and in writing and will indicate in reasonable
detail the identity of the offering party and the terms and conditions of such
proposal, inquiry or contact; except such disclosure will be made to Lamar only
to the extent such disclosure does not violate the fiduciary responsibilities of
the Board of Directors of Bowlin, after being advised by its legal counsel, in
which case Bowlin will provide Lamar with a summary of the terms and conditions
of such proposal, inquiry or contact.

     (5) Nothing contained in this Section 5.5 will prevent Bowlin from
complying with Rule 14e-2(a) or Rule 14d-9 promulgated under the Exchange Act,
if applicable, with regard to an Acquisition Proposal made in the form of a
tender offer by a third party.

     (6) Bowlin shall immediately cease and cause to be terminated any

Proposal; provided, however, that any such discussions may be recommenced so
long as Bowlin complies with the provisions of this Section 5.5.

issuing, and provide each other the opportunity to review and comment upon, any
press releases or other public statements with respect to any transactions

press releases or make any such public statement prior to such consultation,
except as may be required by Applicable Law, court process or by obligations
pursuant to a listing agreement with American Stock Exchange or Nasdaq.

each have the right until the Closing to supplement or amend any of the
Schedules described in Articles 3 or 4 with respect to any matter arising or

date of this Agreement, would have been required to be set forth or described in
such Schedules. For all purposes of this Agreement, including for purposes of
determining whether the conditions set forth in Article 6 have been fulfilled,
the Schedules will be deemed to include only that information contained therein
on the date of this Agreement and will be deemed to exclude all information
contained in any supplement or amendment thereto, except to the extent that they
reflect an event or condition that would not have a Material Adverse Effect on
the party making the representation and warranty; provided, however, that if the
Closing will occur, then all matters disclosed pursuant to any such supplement
or amendment will be deemed included in the Schedules at Closing (without
necessity of a written waiver or other action on the part of any party) and to
modify the applicable representations and warranties for all purposes.

                           FORM OF AFFILIATES' LETTER

Mr. Keith Istre, Vice President and Chief Financial Officer
Lamar Advertising Company
5551 Corporate Blvd.
Baton Rouge, LA 70808

Dear Mr. Istre:

     Pursuant to the Agreement and Plan of Merger dated October 3, 2000 (the
"Merger Agreement") by and among Lamar Advertising Company, a Delaware
corporation ("Lamar"), and Lamar Southwest Acquisition Corporation, a Nevada
corporation and a wholly owned subsidiary of Lamar ("NewCo"), on the one hand,
and Bowlin Outdoor Advertising & Travel Centers Incorporated, a Nevada
corporation ("Bowlin"), I will receive shares of Lamar's Class A Common Stock,
$.001 par value per share (the "Lamar Stock"). I am aware and acknowledge that
as a director or executive officer of Bowlin or the beneficial owner of 10% or
more of the outstanding common stock of Bowlin, I may be deemed an "affiliate"
of the Company as that term is defined in the Securities Act of 1933, as amended
(the "Securities Act"), and the regulations promulgated under the Securities
Act.

     I understand that, as a result of my status as an affiliate of Bowlin, I
may not resell or otherwise dispose of the shares of Lamar Stock that I acquire
pursuant to the Merger Agreement (the "Acquired Shares") except in compliance
with Rule 145 promulgated under the Securities Act.

     On the basis of the foregoing, and in consideration of the delivery to me
of the Acquired Shares, I agree that I will not, directly or indirectly, offer,
sell, transfer, pledge or otherwise alienate, encumber or dispose of any of the
Acquired Shares in violation of the Securities Act or the rules and regulations
promulgated under it.

                                            Very truly yours,

     fines, settlements, damages, or expenses (including, without limitation,
     interest, penalties, costs of preparation and investigation, and the
     reasonable fees, disbursements and expenses of attorneys, accountants and

     Bowlin Indemnitees:

                                       B-6
<PAGE>   120

             (i) arising under federal, state or local environmental laws and
        arising out of or in connection with the Travel Center Business or the
        ownership or operation of any of the Assets or Assumed Liabilities;

             (ii) resulting from any labor or employment dispute arising out of
        or in connection with the operation of the Travel Center Business or
        otherwise involving a Travel Centers Business Employee; and

             (iii) any attempt (whether or not successful) by any Person to
        cause or require Bowlin to discharge or pay any Assumed Liability, or
        otherwise arising out of or relating to any Assumed Liability.

          (b) any and all tax liabilities for which the Company provides
     indemnification to BOWLIN as set forth in the Tax Agreement between the
     Company and BOWLIN, dated as of the date of this Agreement and attached
     hereto as Exhibit A.

     5.3  Control of Litigation.

     (a) The BOWLIN Indemnitees agree to give prompt notice to the Company of
the assertion of any third party claim, or the commencement of any third party
suit, action, or proceeding in respect of which indemnity may be sought under
Section 5.2 of this Agreement and of any Loss which any such Indemnitee deems to
be reimbursable under Section 5.2 of this Agreement (specifying with reasonable
particularity the basis therefore) and will give the Company such information
with respect thereto as the Company may reasonably request; provided, however,
that the failure to give such notice by the Indemnitee shall not abrogate
Indemnitee's rights hereunder unless such failure materially impairs the rights
or ability of the Company to defend the suit, action or proceeding or to
otherwise provide indemnification to the Indemnitee. The Company may, at its own
expense, participate in and, upon notice to such Indemnitee, assume the defense
of any such suit, action or proceeding, provided that the Company's counsel is
reasonably satisfactory to such Indemnitee. The Company shall thereafter consult
with such Indemnitee upon such Indemnitee's reasonable request for such
consultation from time to time with respect to such suit, action, or proceeding,
and the Company shall not, without such Indemnitee's consent, which consent
shall not be unreasonably withheld, settle or compromise any such suit, action
or claim. If the Company assumes such defense, such Indemnitees shall have the
right (but not the duty) to participate in the defense thereof and to employ
counsel, at their own expense, separate from the counsel employed by the
Company. In the event that the Company, within ten days after the notice of any
such action or claim, does not assume the defense thereof, the Indemnitee will
have the right to undertake the defense, compromise or settlement of any action,
claim or proceeding for the account of the Company. For any period during which
the Company has not assumed the defense thereof, the Company shall be liable for
the fees and expenses of counsel employed by any Indemnitee. If the Indemnitees
conduct the defense thereof, the Indemnitees shall consult with the Company upon

                                  ARBITRATION

     If any dispute arises out of this Agreement, the Company and BOWLIN shall,
upon the request of either party, attend a meeting in Baton Rouge, Louisiana
(or, if the Merger has not been consummated, in Albuquerque, New Mexico) to
attempt a resolution of the dispute. If the Company and BOWLIN fail to resolve
all differences at the end of the meeting, they will jointly request the
American Arbitration Association to appoint an arbitrator in Baton Rouge,
Louisiana (or, if the Merger has not been consummated, in Albuquerque, New
Mexico) to settle the dispute in accordance with the Commercial Arbitration
Rules of the American Arbitration Association then in effect. If either party
fails to join in making a joint request for arbitration, then the other party
may make the request unilaterally after giving ten days notice to the party
refusing to join in the request for arbitration. The award rendered by the
arbitrator(s) shall be final and judgment upon the award rendered by the
arbitrator(s) may be entered upon it in any court having jurisdiction thereof.
The arbitrator(s) shall possess the powers to issue mandatory orders and
restraining orders in connection with such arbitration. The expenses of the
arbitration shall be borne by the losing party unless otherwise allocated by the
arbitrator(s); provided, however, that if the dispute is resolved by agreement
of the Company and BOWLIN following the designation of an arbitrator, the
Company and BOWLIN each will pay one-half of any costs and expenses of the
arbitrator already designated. The agreement to arbitrate shall be specifically
enforceable under the prevailing arbitration law. During the continuance of any
arbitration proceedings, the parties shall continue to perform their respective
obligations under this Agreement.

failure to insist upon strict compliance with such obligation, covenant,

respect to, any subsequent or other failure. Whenever this Agreement requests or

compliance as set forth in this Section 7.2, with appropriate notice in

in each instance, give notice to BOWLIN of its exercise of the power of attorney

Centers Business on or before the Distribution Date shall be used to offset the

administrative or judicial proceeding, or (c) the completion of the highest

provided, however, that Restructuring Taxes shall be calculated by assuming that
the aggregate fair market value of the Travel Centers' stock distributed by
Bowlin in the Distribution is equal to (a) the product of (i) the mean between
the high bid and low asked prices for Travel Centers' stock on its first trading
day (as reported in The Wall Street Journal or such other source as Travel
Centers deems reliable) and (ii) the total number of outstanding shares of
Travel Centers stock immediately after the Distribution, or (b) such other
amount as determined by Travel Centers in its reasonable discretion. Travel
Centers shall provide Bowlin with written notification of this valuation within
five (5) days after the Distribution Date. Notwithstanding any provision of this
Agreement to the contrary, if a Claim is successfully asserted by the IRS with
respect to Restructuring Taxes, Restructuring Taxes shall be determined in
accordance with the Final Determination in connection with such Claim.

to the contrary, any Restructuring Taxes that are primarily attributable to
Bowlin's breach of its representations and warranties under Sections 2.01(a)-(c)
shall be regarded as Bowlin Taxes. For purposes of the foregoing, Taxes shall be
deemed attributable to the Travel Centers Business to the extent such Taxes are
imposed as a result of Tax Items of Bowlin or Travel Centers directly related to
the Travel Centers Business; provided, however, that net losses (if any)
incurred with respect to the Outdoor Advertising Business on or before the
Distribution Date shall be used to offset the income of Travel Centers for
purposes of determining Travel Centers Taxes and (to the extent available) shall
be used to offset gain in determining the amount of Restructuring Taxes. To the
extent that a Tax Item is not directly related to either the Travel Center
Business or the Outdoor Advertising Business but is indirectly related to both
businesses (such as an item relating to overhead), it shall be deemed
attributable to the Travel Center Business in the proportion that the revenues
of the Travel Center Business bears to the sum of (i) the revenues of the Travel
Center Business plus (ii) the revenues of the Outdoor Advertising Business.

     3.01  Obligations to File Tax Returns

     (a) Bowlin shall timely file or cause to be filed all Tax Returns with
respect to the Bowlin Affiliated Group, which shall include Travel Centers, for
any period beginning prior to the Distribution and ending on the Distribution
Date; provided, however, that Travel Centers shall prepare and forward to Bowlin
all federal and state income Tax Returns with respect to the Bowlin Affiliated
Group for such periods. Bowlin shall be considered the party required to file
and the party filing the Tax Return with respect to any Tax Return prepared by
Travel Centers pursuant to the preceding sentence.

     (b) Travel Centers shall timely file or cause to be timely filed all Tax
Returns with respect to the Travel Centers for all periods beginning after the
Distribution Date.

     3.02  Obligation to Remit Taxes.  Bowlin and Travel Centers shall each
remit or cause to be remitted any Taxes due in respect of any Tax Return it is
required to file or cause to be filed pursuant to Section 3.01, and shall be
entitled to reimbursement for such payments to the extent provided in Section
3.03.

     3.03  Tax Sharing Obligations and Prior Agreements

     (a) Travel Centers shall be liable for and pay, and shall defend and hold
harmless Bowlin and any other Bowlin Indemnitee for, from and against, any and
all Losses incurred or suffered by Bowlin or one or more of the Bowlin
Indemnitees in connection with (i) any Travel Centers Taxes, (ii) any inaccuracy
or breach of any warranty, representation or covenant that is made by Travel
Centers pursuant to this Agreement, and (iii) any amount determined to be Travel
Centers' liability under Section 3.03(c). In the event that Bowlin receives any
refund of or credit for Taxes for which Travel Centers is responsible under this
Section 3.03(a), Bowlin shall pay Travel Centers an amount equal to such refund
or credit within five business days of Bowlin's receipt of such refund or
credit.

     (b) Bowlin shall be liable for and pay, and shall indemnify, defend, and
hold harmless Travel Centers and any other Travel Centers Indemnitee for, from
and against, any and all Losses incurred or suffered by Travel Centers or one or
more of the Travel Centers Indemnitees in connection with (i) any Bowlin Taxes
and (ii) any inaccuracy or breach of any warranty, representation or covenant
that is made by Bowlin pursuant to this Agreement. In the event that Travel
Centers receives any refund of or credit for Taxes for which Bowlin is
responsible under this Section 3.03(b), Travel Centers shall pay Bowlin an
amount equal to such refund or credit within five business days of Travel
Centers' receipt of such refund or credit.

     (c) Bowlin and Travel Centers will determine the amount of sales, transfer
or other similar taxes or fees (including, without limitation, all real estate,
patent, copyright and trademark transfer taxes and real estate recording fees,
but excluding Restructuring Taxes) payable in connection with the transactions
contemplated by the Contribution Agreement (the "Transaction Taxes"). Bowlin and
Travel Centers shall each file promptly and timely the Tax Returns for such
Transaction Taxes with the appropriate taxing

                                        4
<PAGE>   131

authorities and remit payment of the Transaction Taxes. Travel Centers shall be
liable for Transaction Taxes.

     (d) Except as set forth in this Agreement and in consideration of the
mutual indemnities and other obligations of this Agreement, any and all prior
Tax sharing agreements or practices between any member of the Bowlin Affiliated
Group (other than Travel Centers) and Travel Centers shall be terminated with
respect to the Travel Centers as of the Distribution Date.

     3.04  Period that Includes the Date of Distribution.  To the extent
permitted by law or administrative practice, the taxable year of Travel Centers
shall be treated as closing at the close of the Distribution Date. If it is
necessary for purposes of this Agreement to determine Travel Centers Taxes or
Bowlin Taxes for a taxable year that begins on or before and ends after the
Distribution Date and is not treated under this Section 3.04 as closing at the
close of the Distribution Date, the determination shall be made by assuming that
such taxable year ended on a "closing of the books" basis at the close of the
Distribution Date, except that exemptions, allowances or deductions that are
calculated on an annual basis shall be apportioned on a time basis.

                                   ARTICLE IV

                                    PAYMENTS

     4.01  General Tax Payments.  With respect to any Taxes for which one party
(the "Liable Party") is liable under Section 3.03 and that are to be remitted in
connection with Tax Returns to be filed by the other party (the "Filing Party")
after the Distribution Date pursuant to Sections 3.01 and 3.02, (a) upon the
request of the Filing Party, the Liable Party shall promptly provide to the
Filing Party all information necessary to enable the Filing Party to file such
Tax Returns and (b) assuming compliance by the Liable Party with the Liable
Party's obligations under clause (a) (or written waiver by the Filing Party of
such compliance), the Filing Party shall, not later than ten (10) days prior to
the due date for remitting such Taxes (or, if the due date is within forty-five
(45) days after the Distribution Date, as promptly following the Distribution
Date as possible) provide the Liable Party with a written request showing in
reasonable detail the calculation of the amount of such Liable Party's Taxes
(and any other amounts) owing by the Liable Party to the Filing Party pursuant
to this Agreement. The Liable Party shall have the right to object in writing to
such calculation on or before thirty (30) days after the date on which such
request is provided to the Liable Party, on the grounds that there is
substantial authority that such calculation is incorrect; provided that if the
Liable Party so objects, (i) the Filing Party and the Liable Party shall
promptly submit the dispute to an independent accounting or law firm acceptable
to both the Filing Party and the Liable Party for prompt resolution, whose
decision shall be final and binding on the Filing Party and the Liable Party,
and (ii) the party that such accounting or law firm determines has lost the
dispute shall pay all of the fees and expenses incurred in connection with
submitting such dispute. The Liable Party shall pay to the Filing Party any
amount not in dispute on or before the tenth (10th) day following the receipt of
such request by the Liable Party, with additional amounts to be paid by the
Liable Party (together with interest at the Applicable Federal Rate accruing
from the date on which the Tax in issue is due) promptly upon resolution of any
objection. Payment under this Section 4.01 of an amount determined by an
independent accounting or law firm will not negate any liability of a Liable
Party pursuant to this Agreement by reason of a Final Determination.

     4.02  Other Payments.  Other payments due to a party under Section 3.03
shall be due not later than twenty (20) days after the receipt of notice of a
Final Determination to the effect that the indemnified party is liable for an
indemnified cost, together with interest at a rate equal to the Applicable
Federal Rate from the date on which the indemnifying party receives such
receipt, credit or notice.

     4.03  Notice.  Bowlin and Travel Centers shall give each other prompt
written notice of any payment that may be due under this Agreement.

                                        5
<PAGE>   132

                                   ARTICLE V

                                   TAX AUDITS

     5.01  General.  Except as otherwise provided in this Agreement, each of
Travel Centers and Bowlin (as the case may be, the "Controlling Party") shall
have sole responsibility for all audits or other proceedings with respect to Tax
Returns that it is required to file under Section 3.01. Except as provided in
Section 5.03, the Controlling Party shall have the sole right to contest the
audit or proceeding and to employ advisors of its choice.

     5.02  Indemnified Claims in General.  Bowlin or Travel Centers shall
promptly notify the other in writing upon the receipt of an actual notice of
assessment by the relevant Taxing authority of any proposed adjustment to a Tax
Return that may result in liability of the other party (the "Indemnitor") under
this Agreement. If the Indemnitor is not also the Controlling Party, the
Controlling Party shall provide the Indemnitor with information about the nature
and amounts of the proposed adjustments and, subject to additional rights of the
Indemnitor in certain circumstances under Section 5.03 of this Agreement, shall
permit the Indemnitor to participate in the proceeding at the Indemnitor's own
expense. The Indemnitor shall pay all reasonable expenses (including, but not
limited to, legal and accounting fees) incurred by the Controlling Party in
connection with the assessment or adjustment within seven (7) days after a
written request by the Controlling Party.

     5.03  Certain Federal Income Tax Claims

     (a) Any issues raised by the IRS in any Tax inquiry, audit, examination,
investigation, dispute, litigation or other proceeding that would result in
liability to the Indemnitor under this Agreement are defined as a Claim (a
"Claim"). Except as provided in Section 5.03(d) and notwithstanding any other
provision of this Agreement that may be construed to the contrary, the
Controlling Party agrees to contest any Claim and not to settle any Claim
without prior written consent of the Indemnitor, provided that (i) the
Controlling Party shall provide notice to Indemnitor pursuant to Section 5.02 of
any Claim, and (ii) within thirty (30) days after such notice is received by the
Indemnitor, the Indemnitor shall request in writing that such Claim be
contested. If the Indemnitor requests that the Claim be contested in accordance
with the preceding sentence and such Claim does not materially prejudice any
other IRS claim with respect to matters unrelated to the Claim, the Indemnitor
shall have the right, upon written notice to the Controlling Party and to the
extent permitted under applicable law (assuming cooperation of the Controlling
Party), to assume the defense of such Claim, including employment of counsel
reasonably satisfactory to the Controlling Party and the payment of the fees and
disbursements of such counsel. For this purpose, a Claim does not materially
prejudice any other IRS claim solely because the Tax Calculation with respect to
the Claim indirectly affects such other claim. In the event, however, that the
Indemnitor declines, fails or is otherwise unable to assume the defense of such
Claim, the Controlling Party may employ counsel to defend such Claim and the
Indemnitor shall agree to pay (and shall pay) on demand all out-of-pocket costs,
losses and expenses (including, but not limited to, legal and accounting fees)
paid or incurred by the Controlling Party in connection with contesting such
Claim. The party that has assumed defense of a Claim, after reasonable
consultation with the other party, shall determine the nature of all actions to
be taken to contest such Claim (assuming such determination does not negatively
impact any other claim that the IRS may have with respect to matters unrelated
to the Claim), including (A) whether any action to contest such Claim shall
initially be by way of judicial or administrative proceeding, or both, (B)
whether any such Claim shall be contested by resisting payment thereof or by
paying the same and seeking a refund thereof, and (C) the court or other
judicial body before which judicial action, if any, shall be commenced. To the
extent the Indemnitor is not participating, the Controlling Party shall keep the
Indemnitor (and, upon request by the Indemnitor, its counsel) informed as to the
progress of the contest.

     (b) If the Indemnitor requests that the Controlling Party accept a
settlement of a Claim offered by the IRS and if such Claim may, in the
reasonable discretion of the Controlling Party, be settled without prejudicing
any claims the IRS may have with respect to matters unrelated to the Claim, the
Controlling Party shall either accept such settlement offer or agree with the
Indemnitor that the Indemnitor's liability
                                        6
<PAGE>   133

with respect to such Claim shall be limited to the lesser of (i) an amount
calculated on the basis of such settlement offer plus interest owed to the IRS
on the date that is no more than 45 days after the date of the Indemnitor's
request that the Controlling Party accept such Settlement, or (ii) the amount
calculated on the basis of a Final Determination.

     (c) If the Indemnitor elects to have the Controlling Party pay the Tax
claimed and seek a refund, the Indemnitor shall lend sufficient funds on an
interest-free basis to the Controlling Party (with no net after-tax cost to the
Controlling Party), to cover any applicable indemnity obligations of the
Indemnitor. To the extent such refund claim is ultimately disallowed, the loan
or portion thereof equal to the amount of the refund claim so disallowed shall
be applied against the Indemnitor's obligation to make indemnity payments
pursuant to this Agreement. To the extent such refund claim is allowed, the
Controlling Party shall pay to the Indemnitor all amounts advanced to the
Controlling Party with respect to the indemnity obligation within ten (10) days
of the receipt of such refund (or if the Controlling Party would have received
such refund but for the existence of a counterclaim or other claim not
indemnified by the Indemnitor under this Agreement, within ten (10) days of the
final resolution of the contest), plus an amount equal to any interest received
(or that would have been received) from the IRS that is properly attributable to
such amount.

     (d) Except as provided below, the Controlling Party shall not settle a
Claim that the Indemnitor is entitled to require the Controlling Party to
contest under Section 5.03(a) without the prior written consent of the
Indemnitor. At any time, whether before or after commencing to take any action
pursuant to this Section 5.03 with respect to any Claim, the Controlling Party
may decline to take action with respect to such Claim and may settle such Claim
without the prior written consent of the Indemnitor by notifying the Indemnitor
in writing that the Indemnitor is released from its obligations to indemnify the
Controlling Party with respect to such Claim (which notification shall release
the Indemnitor from such obligations except to the extent the Indemnitor has
agreed in writing that it would be willing to have its liability calculated on
the basis of a settlement offer, as provided in Section 5.03(b), at that point
in the contest) and with respect to any Claim related to such Claim or based on
the outcome of such Claim. If the Controlling Party settles any Claim or
otherwise takes or declines to take any action pursuant to this paragraph, the
Controlling Party shall pay to the Indemnitor any amounts paid or advanced by
the Indemnitor with respect to such Claim (other than amounts payable by the
Indemnitor in connection with a settlement offer pursuant to Section 5.03(b)),
plus interest attributable to such amounts.

                                   ARTICLE VI

                                  COOPERATION

     6.01  General.  Bowlin and Travel Centers shall cooperate with each other
in the filing of any Tax Returns and the conduct of any audit or other
proceeding and each shall execute and deliver such powers of attorney and make
available such other documents as are reasonably necessary to carry out the
intent of this Agreement. Each party agrees to notify the other party in writing
of any audit adjustments that do not result in Tax liability but can be
reasonably expected to affect Tax Returns of the other party or any of its
subsidiaries. Each party agrees to treat the Contribution and Distribution for
all income Tax purposes as not causing the recognition of any income, gain or
loss (except for Restructuring Taxes).

     6.02  Cooperation with Respect to Tax Return Filings, Examinations and Tax
Related Controversies. Each party shall fully cooperate with the other party and
its representatives, in a prompt and timely manner, in connection with the
preparation and filing of, and any inquiry, audit, examination, investigation,
dispute, or litigation involving, any Tax Return required to be filed by any
party pursuant to this Agreement. Such cooperation shall include, but not be
limited to, (a) the execution and delivery of any power of attorney required to
allow each party and its counsel to participate in or control any inquiry, audit
or other administrative proceeding and to assume the defense or prosecution, as
the case may be, of any suit, action or proceeding pursuant to the terms of and
subject to the conditions set forth in Article V of this Agreement, and (b)
making available to the other party, during normal business hours, and within
fifteen (15) days of any written request therefor, all books, records and
information, and the assistance of
                                        7
<PAGE>   134

all officers and employees, necessary or useful in connection with any Tax
inquiry, audit, examination, investigation, dispute, litigation or any other
matter.

                                  ARTICLE VII

                          RETENTION OF RECORDS; ACCESS

     Bowlin and Travel Centers shall:

          (a) retain (for a minimum of five (5) years) records, documents,
     accounting data and other information (including computer data) necessary
     for the preparation and filing of all Tax Returns in respect of Taxes of
     the Bowlin Affiliated Group or Travel Centers or for the audit of such Tax
     Returns; and

          (b) give to the other reasonable access to such records, documents,
     accounting data and other information (including computer data) and to its
     personnel (insuring their cooperation) and premises, for the purpose of the
     current or potential review or audit of such Tax Returns to the extent
     relevant to an obligation or liability of a party under this Agreement or
     applicable law. At any time after the Distribution Date that a party
     proposes to destroy such records, documents, accounting data or other
     information, such party shall first notify the other party in writing and
     such other party shall be entitled to receive such records, documents,
     accounting data or other information proposed to be destroyed.

                                  ARTICLE VIII

                                    DISPUTES

     If Bowlin and Travel Centers cannot agree on any calculation of any
liabilities under this Agreement, such calculation shall be made by any
independent public accounting firm acceptable to both Bowlin and Travel Centers.
The decision of such firm shall be final and binding. The fees and expenses
incurred in connection with such calculation shall be borne by the party that
such independent public accounting firm determines has lost the dispute.

                                   ARTICLE IX

                           TERMINATION OF LIABILITIES

     Notwithstanding any other provision in this Agreement, any liabilities
determined under this Agreement shall survive indefinitely.

                                   ARTICLE X

or supplemented only by written agreement of the parties hereto.

     10.02  Waiver of Compliance; Consents.  Any failure of a party to comply
with any obligation, covenant, agreement or condition herein may be waived by
the other party; provided, however, that any such waiver may be made only by a
written instrument signed by the party granting such waiver, but such waiver or
failure to insist upon strict compliance with such obligation, covenant,
agreement or condition shall not operate as a waiver of, or estoppel with
respect to, any subsequent or other failure. Whenever this Agreement requests or
permits consent by or on behalf of any party hereto, such consent shall be given
in writing in a manner consistent with the requirements for a waiver of
compliance as set forth in this Section 10.02, with appropriate notice in
accordance with Section 10.06 of this Agreement.

be binding upon and inure to the benefit of the parties hereto and their
respective successors and permitted assigns. Any party may assign any of its
rights hereunder but only with the consent of the other party hereto, which
consent shall not be unreasonably withheld, but no such assignment shall relieve
it of its obligations hereunder. Nothing in this Agreement, expressed or
implied, is intended or shall be construed to confer upon any person other than

Board of Directors
BOWLIN Outdoor Advertising & Travel
  Centers, Incorporated
c/o Rudy Miller
Miller Capital Corporation
4909 East McDowell Road
Phoenix, AZ 85008

Attention: Mr. Michael Bowlin
           Chief Executive Officer

Gentlemen:

     You have advised Sanders Morris Harris, Inc. ("SMH") that Lamar Advertising
Company ("Lamar") has proposed to acquire via a merger 100% of the outstanding
common stock of BOWLIN Outdoor Advertising & Travel Centers, Incorporated
("BOWLIN") pursuant to an Agreement and Plan of Merger (the "Agreement"). Under
the Agreement, Lamar proposes to pay a price in the range of approximately $6.30
to $8.00 per share in stock based on the average price of Lamar's common stock
for the 30 days prior to Closing (estimated to be in December, 2000). The
transaction is expected to involve Lamar issuing 725,000 shares of Lamar common
stock. Prior to Closing, certain assets, liabilities and operations of BOWLIN's
corporate offices and travel center business will be "spun off" into a new
public entity. The terms of the transaction are set forth in the September 20,
2000 draft of the Agreement.

     You have requested that SMH act as financial advisor to the Board of
Directors of BOWLIN and issue an opinion ("Opinion") as to the fairness, from a
financial point of view, to the public shareholders of BOWLIN of the terms of
the proposed transaction.

     SMH, as part of its investment banking business, is frequently engaged in
the valuation of businesses and their securities in connection with mergers and
acquisitions, negotiated underwritings, secondary distributions of listed and
unlisted securities, private placements, and valuations for estate, corporate
and other purposes.

     In arriving at our Opinion, we have, among other things:

          1. Reviewed a draft of the Agreement and Plan of Merger dated
     September 20, 2000 (from which we have assumed there will be no material
     changes in the final Agreement);

          2. Reviewed a Letter of Intent from Lamar dated June 15, 2000;

          3. Reviewed BOWLIN audited financials and annual reports for the years
     ended January 31, 2000 and January 31, 1999;

          4. Reviewed BOWLIN unaudited financial statements for the quarters
     ended July 31, 2000 and April 30, 2000;

          5. Reviewed Lamar audited financial statements for the year ended
     December 31, 1999;

          6. Reviewed Lamar unaudited financial statements for the six months
     ended June 30, 2000;

          7. Reviewed Lamar Form S-3 (i.e., prospectus relating to the sale of
     26.2 million shares of Lamar by Clear Channel Communications) dated
     September 8, 2000;

          8. Reviewed BOWLIN Form 10 (i.e., registration statement for the
     travel centers spin-off) draft dated September 14, 2000;

                                       C-1

          9. Reviewed BOWLIN management's outdoor advertising segment budget for
     the year ending January 31, 2001;

          10. Reviewed historical market prices and trading volume for common
     stocks of both BOWLIN and Lamar;

          11. Reviewed recent Lamar equity research reports provided by Lamar
     management;

          12. Reviewed a 1999 Confidential Memorandum prepared by Miller Capital
     Corporation regarding the sale of BOWLIN's travel center segment;

          13. Reviewed BOWLIN's December 17, 1996 Prospectus prepared by HD
     Brous & Co., Inc.;

          14. Discussed various assets, liabilities and operations of BOWLIN
     involved in the Transaction; and

          15. Reviewed such other financial studies and analyses and performed
     such other investigations as we deemed appropriate.

     With your permission, we have assumed and relied upon, without assuming any
responsibility for verification, the accuracy and completeness of all of the
financial and other information provided to, discussed with, or reviewed by or
for us, or publicly available, for purposes of this Opinion, and have further
relied upon the assurances of management of BOWLIN that it is not aware of any
facts that will make such information inaccurate or misleading in any respect
material to our analysis. We have neither made nor obtained any independent
evaluations or appraisals of the assets or liabilities of BOWLIN, nor have we
conducted a physical inspection of the properties and facilities of BOWLIN. We
have assumed that the financial forecasts provided to us by BOWLIN have been
reasonably determined on bases reflecting the best currently available estimates
and judgment of BOWLIN's management as to BOWLIN's future financial performance.
We have further assumed in our analyses that, in, all material respects, such
forecasts and projections will be realized in the amounts and times indicated
thereby. We express no view as to such forecasts or the assumptions on which
they were based. We have relied as to all legal, accounting and tax matters with
respect to the transaction (i.e., the merger and spin-off) on legal counsel,
accountants and other financial advisors of BOWLIN. We were not authorized to
negotiate the terms of the transaction, and we have based our opinion solely
upon the proposed Agreement as negotiated by others. We were not asked to, and
we did not, solicit third party offers to acquire all or part of BOWLIN.

     For purposes of rendering our Opinion, we have assumed, in all respects
material to our analysis, that the representations and warranties of each party
contained in the Agreement are true and correct, that each party will perform
all of the covenants and agreements required to be performed by it under the
Agreement and that all conditions to the consummation of the transaction will be
satisfied without waiver thereof. We have also assumed that all material
governmental, regulatory or other consents and approvals will be obtained and
that in the course of obtaining any necessary governmental, regulatory or other
consents and approvals, or any amendments, modifications or waivers to any
documents to which either BOWLIN or Lamar are party, as contemplated by the
Agreement, no restrictions will be imposed or amendments, modifications or
waivers made that would have any material adverse effect on the consideration to
be received by the public shareholders or the time of such receipt.

     Our Opinion is limited to the fairness, from a financial point of view, of
the proposed transaction to BOWLIN's public shareholders, and we express no
opinion as to the merits of the underlying decision by BOWLIN to engage in the
transaction. We are not expressing an opinion herein as to the prices as which
the Lamar common stock or any other security will trade following the
announcement or consummation of the merger, which may vary depending on any
number of factors, many of which are beyond the control of
                                       C-2

Lamar. We also express no opinion with respect to the price per share or market
for the securities to be received by BOWLIN shareholders in the spin-off. This
Opinion does not constitute a recommendation to any shareholder of BOWLIN as to
how such shareholder should vote with respect to the transaction. Our Opinion
necessarily is based upon market, economic and other conditions as they exist
and can be evaluated on the date hereof, and we assume no responsibility to
update or revise our Opinion based upon circumstances or events occurring after
the date hereof.

     We have acted as financial advisor to the Board of Directors of BOWLIN in
connection with the transaction and will receive a fee for our services,
including for rendering this Opinion. In addition, BOWLIN has agreed to
indemnify us for certain liabilities arising out of our engagement. As we have
previously advised you, in the ordinary course of business, we or our affiliates
may trade in BOWLIN's or Lamar's common stock for our own accounts and for the
accounts of our customers and, accordingly, may at any time hold a long or short
position in such securities.

     Based upon and subject to the foregoing, it is our Opinion that, as of the
date hereof, the financial terms of the proposed transaction are fair to the
public shareholders of BOWLIN from a financial point of view.
