[ERNST & YOUNG LLP LETTERHEAD]
Report of Independent Auditors
Martin Marietta Materials, Inc., as Plan Administrator
We have audited the accompanying statements of net assets available for benefits
of the Martin Marietta Materials, Inc. Performance Sharing Plan (the "Plan") as
of December 31, 1997 and 1996, and the related statements of changes in net
assets available for benefits for the year ended December 31, 1997 and for the
period from October 18, 1996 (inception) to December 31, 1996. These financial
statements are the responsibility of Martin Marietta Materials, Inc., as Plan
Administrator. Our responsibility is to express an opinion on these financial
statements based on our audits.
We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
In our opinion, the financial statements referred to above present fairly, in
all material respects, the net assets available for benefits of the Plan at
December 31, 1997 and 1996, and the changes in the net assets available for
benefits for the year ended December 31, 1997 and for the period from October
18, 1996 (inception) to December 31, 1996, in conformity with generally accepted
accounting principles.
Our audits were performed for the purpose of forming an opinion on the financial
statements taken as a whole. The Fund Information in the statements of net
assets available for benefits and the statements of changes in net assets
available for benefits is presented for purposes of additional analysis rather
than to present the net assets available for benefits and changes in net assets
available for benefits of each fund. The Fund Information has been subjected to
the auditing procedures applied in our audits of the financial statements and,
in our opinion, is fairly stated in all material respects in relation to the
financial statements taken as a whole.

Martin Marietta Materials, Inc.
Performance Sharing Plan
Notes to Financial Statements
December 31, 1997
1. ACCOUNTING POLICIES
The financial statements of the Martin Marietta Materials, Inc. Performance
Sharing Plan (the "Plan") are prepared on the accrual basis of accounting. No
liability is recorded for distributions to participants who terminated during
the year but have chosen to defer payments to the following year. The assets of
the plan are held and invested on a commingled basis in the Martin Marietta
Materials, Inc. Defined Contribution Plans Master Trust (the "Master Trust")
along with the assets of the Martin Marietta Materials, Inc. Savings and
Investment Plan for Hourly Employees and the Martin Marietta Materials, Inc.
Money Accumulation Plan for Hourly Employees. The Plan's interest in the Master
Trust is stated at the fair value of the underlying net assets in the Master
Trust. Unrealized appreciation or depreciation in the aggregate and the gain or
loss on disposition of investments during the year are determined using the
average cost of investments. The assets, realized and unrealized gains and
losses and investment income of the Master Trust are allocated among the
participating plans on a pro rata basis. All administrative expenses, a portion
of which are paid by Martin Marietta Materials, Inc., (the "Corporation") are
otherwise paid by the Master Trust and allocated to each of the participating
plans.
Prior to October 1996, the Plan was not part of the Master Trust. Rather, the
Plan's assets were invested in a master trust arrangement established for
various plans affiliated with Lockheed Martin Corporation, the former parent of
Corporation. During October 1996, the Plan's assets were transferred directly
from the master trust arrangement affiliated with Lockheed Martin Corporation
into the Master Trust established for the plans sponsored by the Corporation and
for certain other employees of members of the Corporation's controlled group of
companies, as defined by Section 1563(a)(1) of the Internal Revenue Code ("IRC
Section 1563(a)(1)").
The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions, in
particular the determination of fair values of investments for which market
values are not readily available. Actual results could differ from those
estimates.

Performance Sharing Plan
Notes to Financial Statements (continued)
2. DESCRIPTION OF THE PLAN
In October 1996, Lockheed Martin Corporation disposed of its remaining ownership
interest of the Corporation's common stock by means of a split-off, an exchange
offer whereby Lockheed Martin Corporation's shareholders were given the
opportunity to exchange some or all of their common stock of Lockheed Martin
Corporation for shares of the Corporation's common stock. The Corporation
subsequently registered its common stock for use in connection with the Plan.
In connection with the divestiture of Lockheed Martin Corporation's ownership
interest in the Corporation, the Plan was established effective October 18,
1996, as a defined contribution plan providing eligible salaried employees an
opportunity to participate in an individual savings and investment program
providing tax savings and retirement incentives. Martin Marietta Materials,
Inc., is the Plan's sponsor, and also serves as the Plan administrator. Prior to
October 1996, eligible employees participated in the Lockheed Martin Corporation
Performance Sharing Plan, which was sponsored by Lockheed Martin Corporation.
Employees of the Corporation and certain employees of members of the Lockheed
Martin Corporation controlled group of companies, as defined by IRC Section
1563(a)(1), were eligible to participate in the Plan.
Generally, the terms of - as well as the procedures for administering - the new
Plan did not change. However, certain investment option funds available under
the former plan were replaced with similar funds of the same type of risk and
level of return. The risk and return investment objectives for the new funds in
the Plan are similar to the investment objectives that existed in the former
plan. Additionally, the underlying investment option available in the employer's
company common stock fund was changed from Lockheed Martin Corporation common
stock to that of Martin Marietta Materials, Inc. Following the consummation date
of the split-off, Plan participants are no longer able to make any
participant-directed contributions into the Lockheed Martin Common Stock Fund
nor add to an existing balance in a Lockheed Martin Common Stock Fund by
purchasing additional shares of the underlying common stock. For the period
through October 1998, Plan participants may transfer out any balance in the
Lockheed Martin Common Stock Fund and any such balance is available for
withdrawals, as permitted under the Plan. At the end of this period,
participation in the Lockheed Martin Common Stock Fund will be terminated and
any participants' remaining balances will be liquidated and reinvested
automatically in the Yield-Enhanced Short-Term Investment Fund. No other
significant plan changes were made as a result of the split-off transaction.

Performance Sharing Plan
Notes to Financial Statements (continued)
2. DESCRIPTION OF THE PLAN (CONTINUED)
Employees are eligible to enroll in the Plan after six months of service.
Employee participation requires employee basic contributions of 1% to 6% of base
salary (as defined in the Plan and subject to applicable Internal Revenue Code
("IRC") limitations on allowable compensation). For participants with at least
three years of service on January 1 of each applicable Plan year, the maximum
percentage of employee basic contributions may be increased to 7% of base
salary. Participants may also elect to make additional supplemental
contributions which are not considered for purposes of computing the employer
match. A participant's combined basic and supplemental contributions may not
exceed 17% of that participant's base pay. Generally, a participant's before-tax
contributions may not exceed 15% of base pay, subject to certain restrictions
for highly compensated employees, as defined.
The Corporation matches the participants' annual basic contribution (the first
6% or 7% of base pay, depending upon length of service). The amount of the
Corporation's match is equal to 50% of the basic contributions and is credited
to participant accounts monthly. All participants are 100% vested in the value
of their accounts, including employer contributions.
Participants may change the overall percentage of their contributions in 1%
increments and may change investment elections for future before-tax, after-tax
and matching contributions, both up to once per month. Any changes in investment
elections must be made in 5% increments. In addition, participants may change
the investment mix of the accumulated value of prior contributions among the
investment options - excluding the Lockheed Martin Common Stock Fund - daily,
but are limited to 12 changes in a calendar year, however not less than one
transfer in a calendar quarter. The Plan provides for participants to borrow
from the money in his or her own investment account. All loans must meet
specific terms and conditions of the Plan and are subject to applicable IRC
regulations. Personal loans are available to participants in terms of up to 4
1/2 years, and primary residence loans are available for terms of up to 15
years. Such loans bear interest at a fixed rate, established upon loan request,
which is equal to the annual prime rate (based upon corporate borrowing rates
posted by at least 75% of the nation's 30 largest banks, as reported in The Wall
Street Journal on the first business day of the calendar month before loan
application) plus 1%. All loans are due in full immediately upon termination of
employment. Approximately $936,000 was loaned to participants for the year ended
December 31, 1997. Approximately $63,000 was loaned to participants for the
period from October 18, 1996 (inception), through December 31, 1996. Outstanding
loan balances and loan-related activities

Martin Marietta Materials, Inc.
Performance Sharing Plan
Notes to Financial Statements (continued)
2. DESCRIPTION OF THE PLAN (CONTINUED)
are reflected in the Loan Fund account in the accompanying financial statements.
In addition, the plan provides for in-service withdrawals to participants that
meet specific conditions of financial hardship, as defined in the Plan and in
accordance with current specific regulations under the IRC. Participants who are
still working at the age of 59 1/2 may qualify for special withdrawal rights and
privileges as defined in the Plan.
Upon separation from the Corporation, participants may receive the full current
value of their contributions and the matching employer contributions.
Participants who have attained age 55 may receive their distributions in the
form of a lump-sum payment or in annual installments over a period of up to 25
years. The accounts of participants who receive installment payments remain
invested in the funds indicated by the participant.
During 1996, the Plan received $67,740,000 from the Lockheed Martin Corporation
Performance Sharing Plan. This amount represents the transfer of account
balances of eligible participants pursuant to the establishment of the Plan.
State Street Bank and Trust Company is the trustee of the Master Trust and
recordkeeper of the Master Trust and Plan.
Although the Corporation expects to continue the Plan indefinitely, the Board of
Directors of the Corporation may terminate the Plan for any reason at any time.
If the Plan is terminated, each participant or former participant shall receive
a payment equal to the value of the participant's account.
3. INCOME TAX STATUS
The Plan has received a favorable determination letter from the Internal Revenue
Service (IRS). The determination letter states that the Plan meets the
qualification requirements under the Internal Revenue Code (IRC) Section 401(a)
for tax-exempt status under the IRC Section 501(a). Management believes that the
Plan has been in operational compliance with the IRC Section 401(a)
requirements. Therefore, no provision has been made in the financial statements
for federal income taxes.

Notes to Financial Statements (continued)
4. MASTER TRUST
The Plan's interest in the Master Trust's net assets as of December 31, 1997 and
1996, was 86.55% and 87.21%, respectively. The Plan's interest in the Master
Trust did not fluctuate significantly throughout the year ended December 31,
1997 or the period from October 18, 1996 (inception) through December 31, 1996.
The following audited financial statements of the Master Trust contain
additional information concerning the Plan's interest in the Master Trust.
5. YEAR 2000 ISSUE (UNAUDITED)
The Corporation has established a dedicated information technology task force to
coordinate the identification, evaluation and implementation of modifications
and replacements to the Corporation's information systems and related
applications necessary to achieve a year 2000 date conversion with no effect on
customers or disruption to its business operations. The Corporation's goal is to
be substantially year 2000 compliant on a timely basis. The major systems and
applications carrying potential business impact have been identified and are
being evaluated, and initial conversion efforts are underway. In addition, the
Corporation is communicating with suppliers, customers, financial institutions
and others with which it does business to coordinate the year 2000 conversion
process. The cost of the year 2000 initiatives is not expected to be material to
the Corporation's results of operations or financial position or to the Plan's
operations.
6. PLAN AMENDMENTS
Effective January 1, 1998, salaried employees of the former American Aggregates
Corporation, that was acquired by the Corporation during 1997, are eligible to
participate in the Plan.
Effective January 1, 1998, the following investment options were eliminated:
Intermediate Bond Fund, Investment Company of America and American Balanced
Fund.

[ERNST & YOUNG LLP LETTERHEAD]
Report of Independent Auditors
Martin Marietta Materials, Inc., as Plan Administrator
We have audited the accompanying statements of net assets available for benefits
of the Martin Marietta Materials, Inc. Defined Contribution Plans Master Trust
(the "Master Trust") as of December 31, 1997 and 1996 and the related statements
of changes in net assets available for benefits for the year ended December 31,
1997 and for the period from October 18, 1996 (inception) through December 31,
1996. These financial statements are the responsibility of Martin Marietta
Materials, Inc., as Plan Administrator. Our responsibility is to express an
opinion on these financial statements based on our audits.
We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
In our opinion, the financial statements referred to above present fairly, in
all material respects, the net assets available for benefits of the Master Trust
at December 31, 1997 and 1996, and the changes in the net assets available for
benefits for the year ended December 31, 1997 and for the period from October
18, 1996 (inception) through December 31, 1996, in conformity with generally
accepted accounting principles.
The accompanying statements are those of the Martin Marietta Materials, Inc.
Defined Contribution Plans Master Trust, which is established under the Martin
Marietta Materials, Inc. Performance Sharing Plan, the Martin Marietta
Materials, Inc. Savings and Investment Plan for Hourly Employees and the Martin
Marietta Materials, Inc. Money Accumulation Plan for Hourly Employees
(collectively, the "Plans"); the statements do not purport to present the
financial status of the Plans. The statements do not contain certain information
on net assets available for benefits and other disclosures necessary for a fair
presentation of the financial statements of the Plans in conformity with
generally accepted accounting principles. Furthermore, these statements do not
purport to satisfy the Department of Labor's Rules and Regulations for Reporting
and Disclosure under the Employee Retirement Income Security Act of 1974
relating to the financial statements of employee benefit plans.

<PAGE> 15
Our audits were performed for the purpose of forming an opinion on the financial
statements taken as a whole. The Fund Information in the statements of net
assets available for benefits and the statements of changes in net assets
available for benefits is presented for purposes of additional analysis rather
than to present the net assets available for benefits and changes in net assets
available for benefits of each fund. The Fund Information has been subjected to
the auditing procedures applied in our audit of the financial statements and, in
our opinion, is fairly stated in all material respects in relation to the
financial statements taken as a whole.

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions, in
particular the determination of fair values of investments for which market
values are not readily available. Actual results could differ from those
estimates.

2. DESCRIPTION OF THE MASTER TRUST
Plan assets held by the Master Trust are invested in eleven funds. The
Yield-Enhanced Short-Term Investment Fund, which is managed by the trustee, is
invested in high-quality money market instruments, corporate equity and debt
instruments and U.S. Government secured notes and bonds. The S&P 500 Index Fund,
which is managed by the trustee, invests in the same individual common stocks in
identical proportions to the S&P 500 index. The Martin Marietta Materials Common
Stock Fund is composed of the Corporation's common stock. The Lockheed Martin
Common Stock Fund is composed of the common stock of Lockheed Martin
Corporation. The Harbor Capital Appreciation Fund is designed to seek long-term
growth of capital by investing in stocks of domestic and foreign companies with
high equity capitalization with above average prospects for growth. The
Intermediate Bond Fund, which is managed by the trustee, invests primarily in
U.S. Treasury, Agency, corporate and asset backed bonds. The Investment Company
of America Fund is designed to achieve long-term growth of capital and income by
investing in stocks of well-established "blue-chip" companies of both the U.S.
and abroad, as well as, in U.S. Government securities. The American Balanced
Fund is designed to seek conservation of capital, current income and long-term
growth of capital by investing in a blend of stocks, bonds and other fixed
income securities. The Daily Bond Market Fund, which is managed by the trustee,
invests primarily in U.S. Treasury, Agency, corporate, mortgage backed and asset
backed securities. The Vanguard Windsor Fund is a capital growth and income fund
that will invest primarily in a diversified portfolio of U.S. common stocks
thought to be undervalued. The Vanguard International Growth Fund is designed to
achieve long-term growth of capital by investing in equity securities of
non-U.S. Companies. Effective January 1, 1998, the following investment options
were eliminated: Intermediate Bond Fund, Investment Company of America and
American Balanced Fund.
The Martin Marietta Materials, Inc. Performance Sharing Plan has a loan program
whereby eligible participants may borrow up to the lesser of 50% of their total
account balance less the highest outstanding loan balance from the past twelve
months, or $50,000 with a minimum loan of $500. Loans are repaid monthly over a
term of up to 4 1/2 years for personal loans and up to 15 years for a
residential loan at an interest rate of one percent over the prime rate reported
by at least 75% of the nation's 30 largest banks as reported in The Wall Street
Journal on the first business day of the month before loan application. All
loans are due in full immediately upon termination of employment. Approximately
$1,582,000 and $1,241,000 was loaned to participants at December 31, 1997 and
1996, respectively. Participant loan activity and the net outstanding loan
balances are reflected in the Loan Fund in the accompanying financial
statements.

2. DESCRIPTION OF THE MASTER TRUST (CONTINUED)
Fair values of the underlying securities in the Yield-Enhanced Short-Term
Investment Fund, the S&P 500 Index Fund, the Intermediate Bond Fund, and the
Daily Bond Market Fund are determined by closing prices on the last business day
of the year for those securities traded on national exchanges, at the most
recent sales prices for those securities traded in over-the-counter markets and
at fair value as determined by the Trustee for securities for which there is not
an established market. The fair value of Martin Marietta Materials common stock
and Lockheed Martin Corporation common stock is determined by the closing price
per share on the last business day of the year as reported for New York Stock
Exchange Composite Transactions. Fair values of the Harbor Capital Appreciation
Fund, the Investment Company of America Fund, the American Balanced Fund, the
Vanguard Windsor Fund, and the Vanguard International Growth Fund are determined
by the closing prices on the last business day of the year.
Following the creation of the Master Trust, the Plans' participants are no
longer able to make any participant-directed contributions into the Lockheed
Martin Common Stock Fund nor add to an existing balance in a Lockheed Martin
Common Stock Fund by purchasing additional shares of the underlying common
stock. For the period through October 1998, the Plans' participants may transfer
out any balance in the Lockheed Martin Common Stock Fund and any such balance is
available for withdrawals, as permitted under the Plans. At the end of this
period, participation in the Lockheed Martin Common Stock Fund will be
terminated and any participants' remaining balances will be liquidated and
reinvested automatically in the Yield-Enhanced Short-Term Investment Fund.
Administrative expenses, a portion of which are paid by the Corporation, are
otherwise paid from the Trust and allocated to the Plans on a pro rata basis.
3. INVESTMENTS
The fair values of individual investments that represent 5% or more of the
Master Trust's net assets at December 31, 1997 are as follows (in thousands):

4. INCOME TAXES
The Master Trust was created to hold the assets of the various defined
contribution plans of the Corporation which are listed as participating plans in
the Master Trust Agreement. As Plans participating in the Master Trust have
received favorable determination letters from the Internal Revenue Service that
they are qualified under Section 401(a) of the Internal Revenue Code, and
management believes the Plans to be operating in compliance with all applicable
requirements, there has been no provision for federal income taxes in the
financial statements.
5. YEAR 2000 ISSUE (UNAUDITED)
The Corporation has established a dedicated information technology task force to
coordinate the identification, evaluation and implementation of modifications
and replacements to the Corporation's information systems and related
applications necessary to achieve a year 2000 date conversion with no effect on
customers or disruption to its business operations. The Corporation's goal is to
be substantially year 2000 compliant on a timely basis. The major systems and
applications carrying potential business impact have been identified and are
being evaluated, and initial conversion efforts are underway. In addition, the
Corporation is communicating with suppliers, customers, financial institutions
and others with which it does business to coordinate the year 2000 conversion
process. The cost of the year 2000 initiatives is not expected to be material to
the Corporation's results of operations or financial position or to the Plans'
operations.
