See accompanying notes to condensed consolidated financial statements. Page 5 6 MARTIN MARIETTA MATERIALS, INC. AND CONSOLIDATED SUBSIDIARIES FORM 10-Q For the Quarter Ended September 30, 1996 NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS 1. The accompanying unaudited condensed consolidated financial statements of Martin Marietta Materials, Inc. (the "Corporation") have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions to the Quarterly Report on Form 10-Q and to Article 10 of Regulation S-X. The Corporation has continued to follow the accounting policies set forth in the audited consolidated financial statements and related notes thereto included in the Corporation's Annual Report on Form 10-K for the year ended December 31, 1995, filed with the Securities and Exchange Commission on March 27, 1996. In the opinion of management, the interim financial information provided herein reflects all adjustments (consisting of normal recurring accruals) necessary for a fair presentation of the results of operations for the interim periods. The results of operations for the nine months ended September 30, 1996, are not necessarily indicative of the results to be expected for the full year. During 1993, the Board of Directors of Lockheed Martin Corporation ("Lockheed Martin") approved a plan to form a new subsidiary, Martin Marietta Materials, Inc. Under the plan, Lockheed Martin transferred to the Corporation its ownership interest in the construction aggregates business along with its ownership of 100% of the common stock of Martin Marietta Magnesia Specialties Inc. The Corporation, which was incorporated on November 12, 1993, consummated an initial public offering (an "IPO") of 8,797,500 shares (approximately 19%) of its outstanding Common Stock in February 1994. Upon completion of the IPO, Lockheed Martin's beneficial ownership of the Corporation's outstanding Common Stock was reduced to approximately 81%. Lockheed Martin disposed of its remaining ownership in October 1996 by means of a split-off, an exchange offer whereby Lockheed Martin stockholders were given the opportunity to exchange some or all of their shares of Lockheed Martin common stock for a certain number of shares of the Corporation's Common Stock held by Lockheed Martin. For a more detailed discussion of this transaction, see the "Overview" section of the "Management's Discussion and Analysis of Financial Condition and Results of Operations" on page 9. For purposes of these financial statements and the related notes thereto, all references to Lockheed Martin, which was formed as a result of a business combination in March 1995 between the Martin Marietta Corporation and the Lockheed Corporation, are meant to include Martin Marietta Corporation and its consolidated subsidiaries, except where otherwise specified. Additionally, transactions with Lockheed Martin remain classified and accounted for as related party transactions for financial reporting purposes. 2. Inventories:

September 30, December 31, 1996 1995 ------------- ------------ (Dollars in Thousands) 7% Debentures, due 2025 $124,183 $124,177 8-1/2% Notes, due 1996 -- 100,000 Acquisition notes, interest rates ranging from 6% to 10% 88 3,675 Other notes 726 874 -------- -------- 124,997 228,726 Less current maturities (190) (103,740) -------- -------- Total $124,807 $124,986 ======== ========
The 8-1/2% Notes were redeemed by the holders upon their maturity on March 1, 1996. During the period these Notes were outstanding, Lockheed Martin reimbursed the Corporation for the portion of the interest in excess of 5% per annum. In addition to the above stated long-term debt, as of September 30, 1996, the Corporation had borrowed, from a subsidiary of Lockheed Martin, $10.8 million under the terms of its credit agreements. For financial reporting purposes, this amount remains classified with affiliates payable in the accompanying financial statements. These borrowing proceeds were used primarily to help finance the repayment of the 8-1/2% Notes and to assist funding the Corporation's working capital requirements during the first nine months of 1996. As of November 1, 1996, no amount was outstanding under the terms of this agreement. The Corporation's interest payments were approximately $7.6 million in 1996 and $8.3 million in 1995 for the nine months ended September 30. 4. Income Taxes The Corporation's effective income tax rate for the first nine months was 33.9% in 1996 and 35.5% in 1995. The effective rate for the first three quarters of 1996 was lower than the current federal corporate income tax rate of 35%, due to the effect of several partially offsetting factors. The Corporation's year-to-date 1996 effective tax rate reflects the effect of state income taxes which has been more than offset by the favorable impact of differences in book and tax accounting arising from the permanent benefits associated with the depletion allowances for mineral reserves, foreign subsidiaries' operating earnings, and equity earnings in nonconsolidated investments. Page 7 8 MARTIN MARIETTA MATERIALS, INC. AND CONSOLIDATED SUBSIDIARIES FORM 10-Q For the Quarter Ended September 30, 1996 NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Continued) 4. Income Taxes (continued) The results of operations of the Corporation through the effective date of the consummation of the split-off from Lockheed Martin are included in a consolidated federal income tax return with Lockheed Martin. However, following the effective date of the consummation of the split-off, as discussed in Note 1 and in the "Overview" section of the "Management's Discussion and Analysis of Financial Condition and Results of Operations" on page 9, the Corporation will file consolidated federal income tax returns independently from Lockheed Martin. For years ended prior to January 1, 1995, the Corporation's results of operations are included in the consolidated federal income tax returns with Martin Marietta Corporation. Income taxes allocable to the operations of the Corporation are calculated as if it had filed separate income tax returns for the periods presented herein. For all periods following the consummation of the split-off from Lockheed Martin, recognition and measurement of the Corporation's current and deferred income tax liabilities and assets will be presented under the financial accounting and reporting standards for the effects of income taxes that result from the Corporation's activities on a stand-alone basis. The Corporation will file separate income tax returns for all periods following the consummation date of the split-off. The Corporation's income tax payments were approximately $22.9 million in 1996 and $9.8 million in 1995, for the nine months ended September 30. 5. Contingencies In the opinion of management and counsel, it is unlikely that the outcome of litigation and other proceedings, including those pertaining to environmental matters, relating to the Corporation and its subsidiaries, will have a material adverse effect on the results of the Corporation's operations or its financial position. 6. Other Matters In February 1994, the Corporation was authorized by its shareholders and the Board of Directors to repurchase up to 2,000,000 shares of the Corporation's Common Stock for issuance under the Corporation's Amended Omnibus Securities Award Plan. On May 3, 1994, the Board of Directors authorized the repurchase of an additional 500,000 shares for general corporate purposes. As of November 1, 1996, there have been 68,200 shares of Common Stock repurchased by the Corporation under these authorizations. Page 8 9 MARTIN MARIETTA MATERIALS, INC. AND CONSOLIDATED SUBSIDIARIES FORM 10-Q For the Quarter Ended September 30, 1996 MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS Third Quarter and Nine Months Ended September 30, 1996 and 1995 OVERVIEW Martin Marietta Materials, Inc., (the "Corporation") was created after the Board of Directors of Lockheed Martin Corporation ("Lockheed Martin") approved a plan under which Lockheed Martin transferred to the Corporation its ownership interest in the construction aggregates business along with its ownership of 100% of the common stock of Martin Marietta Magnesia Specialties Inc. The Corporation was incorporated on November 12, 1993, and consummated an initial public offering of 8,797,500 shares of its Common Stock in February 1994. Upon completion of the initial public offering, Lockheed Martin's beneficial ownership of the Corporation's Common Stock was reduced to approximately 81% of the Corporation's outstanding Common Stock. Lockheed Martin disposed of its remaining ownership interest in the Corporation in October 1996, by means of a split-off, an exchange offer pursuant to which Lockheed Martin stockholders were given the opportunity to exchange some or all of their shares of Lockheed Martin common stock for a certain number of shares of the Corporation's Common Stock (the "Exchange Offer") on a tax-free basis. As a result of this transaction, all of Lockheed Martin's approximately 81% interest in the Corporation's Common Stock was exchanged with Lockheed Martin stockholders who participated in the Exchange Offer. Consummation of the Exchange Offer did not impact the Corporation's financial position or its results of operations as of the consummation date of the transaction and for the period then ended. For additional discussion in connection with the Exchange Offer, see "Other Matters" on page 15. The Corporation reports operations in two industry reporting segments, aggregates and magnesia-based products. The Corporation is the United States' second largest producer of aggregates used for the construction of highways and other infrastructure projects and for commercial and residential construction. The Corporation's Aggregates division processes or ships aggregates, primarily crushed stone, from a network of approximately 200 quarries and distribution facilities in 19 states in the southeastern, midwestern and central regions of the United States and in the Bahamas and Canada. The Corporation also manufacturers and markets magnesia-based products, including heat-resistant refractory products for the steel industry and magnesia-based chemical products for industrial, agricultural and environmental uses, including wastewater treatment and acid neutralization. The Corporation continued in excellent overall financial condition during the third quarter of 1996 and has adequate capital resources to operate, compete and grow in an increasingly challenging and competitive environment. Net earnings for the third quarter of 1996 were $27.5 million, or $0.60 per share, an increase of 17% over 1995 third-quarter earnings of $23.4 million, or $0.51 per share. Page 9 10 MARTIN MARIETTA MATERIALS, INC. AND CONSOLIDATED SUBSIDIARIES FORM 10-Q For the Quarter Ended September 30, 1996 MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (Continued) Third Quarter and Nine Months Ended September 30, 1996 and 1995 At September 30, 1996, total shareholders' equity reached $466.5 million, and the Corporation's ratio of debt to total capitalization was 23%, compared with a debt-to-capitalization ratio of 35% at year-end 1995. Total debt at year-end reflected a temporary increase in long-term debt associated with the December 1995 sale of the Corporation's $125 million 7% Debentures. The proceeds from the sale of these Debentures were used ultimately to repay the $100 million aggregate principal amount of the Corporation's 8-1/2% Notes upon their maturity on March 1, 1996. RESULTS OF OPERATIONS Net sales for the quarter were $201.5 million, a 5% increase over 1995 third quarter sales of $191.1 million. Net sales for the first nine months of 1996 were $538.5 million, an increase of 8% over net sales for the year-earlier period of $497.0 million. Earnings from operations were up $6.0 million, or 16%, to $43.1 million for the third quarter of 1996 over the same period in 1995, with earnings from operations up $8.9 million, to $91.5 million for the first nine months of 1996, compared with the first nine months of 1995. Consolidated net earnings for the quarter increased 17% to $27.5 million, or $0.60 per share, from 1995 third quarter net earnings of $23.4 million, or $0.51 per share. For the nine-month period ended September 30, 1996, consolidated net earnings were $58.6 million, or $1.27 per share. This represents an increase of 14% over net earnings for the first nine months of 1995 of $51.6 million, or $1.12 per share. Sales for the Aggregates division increased 6% to $169.5 million for the third quarter, compared with the year-earlier period. The division's sales increased 9% to $440.8 million for the first nine months of 1996, compared with the first nine months of 1995. This increase in sales reflects record year-to-date aggregates shipments of 75.3 million tons and an increase in the division's average net selling price, when compared to the same period in 1995. The division's third quarter operating profits were $40.5 million, an increase of 18% over operating profits for the year-earlier period of $34.4 million. The division's operating profits for the first nine months of 1996 increased 9% to $83.7 million from $76.8 million for the first nine months of 1995, despite the effect of Hurricane Fran and subsequent heavy rainfall during September in the southeast and the effect of the adverse weather conditions that existed within most of the markets served by the division during the first quarter of 1996. The Corporation's aggregates business is highly seasonal, due primarily to the effect of weather conditions on construction activity levels, most of which occurs typically in the spring, summer, and early fall. Production costs were negatively affected by the severe winter weather conditions experienced during the first quarter, along with the hurricane and related wet conditions that existed during the third quarter of this year. Management continues to believe that the Corporation's annual production and shipments, excluding any acquisition activities, will see some improvement for the full year ending December 31, 1996, compared with the prior year. The Magnesia Specialties division had third quarter 1996 sales of $32.0 million, a slight increase over the third quarter sales of 1995, and had nine month 1996 sales of $97.7 million, an increase of 4% in 1996 over 1995. The division's operating earnings for the third quarter of $2.5 million were 3% below the operating results for the prior-year period as a result of an explosion and fire in an electrical substation, which occurred at the Woodville, Ohio, lime plant during the latter part of the second quarter of this year. For the nine-month period, the division's earnings from operations increased substantially from $5.9 million in 1995 to $7.8 million in 1996. This increase principally reflects the negative effect of the strike which occurred during 1995 at a major operating location. Page 10 11 MARTIN MARIETTA MATERIALS, INC.

Other income and expenses, net, for the nine months ended September 30, were $5.2 million in income in 1996 and $4.4 million in income in 1995. In addition to several offsetting amounts, the 1996 amount included nonrecurring pretax gains of approximately $1.2 million associated with the selling of certain assets and approximately $1.2 million of interest income from affiliates loans. The 1995 amount also included a nonrecurring pretax gain of approximately $1.4 million related to certain Page 12 13 MARTIN MARIETTA MATERIALS, INC. AND CONSOLIDATED SUBSIDIARIES FORM 10-Q For the Quarter Ended September 30, 1996 MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (Continued) Third Quarter and Nine Months Ended September 30, 1996 and 1995 asset dispositions in connection with one of the Corporation's equity investments and $0.9 million of interest income from loans to affiliates. It should be noted that interest income from loans to Lockheed Martin has remained classified with transactions with affiliates for financial reporting purposes. Interest expense was approximately $1.0 million, or 16%, higher in the first nine months of 1996 over 1995. The increase in 1996 resulted from the net effect of the additional long-term borrowings by the Corporation in December 1995, when the Corporation publicly offered and sold its $125 million 7% Debentures, offset by the reduction of long-term debt during the period caused by the repayment of the 8 1/2% Notes on March 1, 1996, and the reduced amounts outstanding during the period that were due to Lockheed Martin under the credit agreement. The Corporation's estimated effective income tax rate for the first nine months was 33.9% in 1996 and 35.5% in 1995. See Note 4 of the Notes to Condensed Consolidated Financial Statements. LIQUIDITY AND CAPITAL RESOURCES Net cash flow provided by operating activities during the first nine months of 1996 was $71.9 million, compared with $85.5 million in the comparable period of 1995. The cash flow from operating activities for both 1995 and 1996 was principally from earnings, before deducting depreciation, depletion and amortization, offset by increased demand for working capital. Working capital increases during the first nine months of 1996 were principally due to an increase in accounts receivable balances as a result of growth in aggregates demand. The increased demand on working capital during the first nine months of 1995 was primarily the result of increases in inventory and accounts receivable balances, both of which were offset somewhat by increased trade accounts payable and other liabilities balances. The seasonal nature of the construction aggregates business impacts quarterly net cash provided by operating activities when compared with the year. Accordingly, full year 1995 net cash provided by operating activities was $128.6 million, compared with the $85.5 million provided by operations in the first nine months of 1995. Capital expenditures are expected to be approximately $83 million for 1996, exclusive of acquisitions. Comparable capital expenditures, were $71.6 million in 1995. Page 13 14 MARTIN MARIETTA MATERIALS, INC. AND CONSOLIDATED SUBSIDIARIES FORM 10-Q For the Quarter Ended September 30, 1996 MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (Continued) Third Quarter and Nine Months Ended September 30, 1996 and 1995 The Corporation relies, for its liquidity requirements, upon internally generated funds, access to capital markets, and funds obtained under its cash management agreement and credit agreement, each with its former majority shareholder, Lockheed Martin. Prospectively, management may choose to borrow from third-party lenders or through the Corporation's access to capital markets. The above-referenced credit agreement with Lockheed Martin, which may be extended by mutual consent of both parties, provides for borrowings of up to $55 million. Loans outstanding under the credit agreement bear interest at a published prime interest rate or at LIBOR plus a graduated rate. During the fourth quarter of 1996, management expects to establish a revolving credit facility with a syndicate of banks to replace the current credit agreements with Lockheed Martin. It should be noted, however, that the Corporation has not determined the specific timing when, or method by which, it may establish and access such a banking credit facility. Further, while any such borrowings may be used initially to provide necessary working capital funds, it is anticipated that the Corporation will repay the funds borrowed under its credit agreement with Lockheed Martin with such bank borrowings. Additionally, management may choose at some future time to further access the public debt markets through the issuance of commercial paper or other debt securities. Again, it should be noted that the Corporation has not determined the method or methods by which it may further access the public market. With respect to the Corporation's ability to access the public market, it has an effective shelf registration on file with the Securities and Exchange Commissions for the offering of up to $175 million of debt securities, which may be issued from time to time. The Corporation's ability to issue such debt securities at any time is dependent, among other things, upon market conditions. Based on prior performance and current expectations, the Corporation's management believes that cash flows from internally generated funds and its access to capital markets are expected to continue to be sufficient to provide the capital resources necessary to fund the operating needs of its existing businesses, cover debt service requirements, and allow for payment of dividends. The Corporation may be required to obtain additional levels of financing in order to fund certain strategic acquisitions if any such opportunities arise. Currently, the Corporation's senior unsecured debt is rated "A" by Standard & Page 14 15 MARTIN MARIETTA MATERIALS, INC. AND CONSOLIDATED SUBSIDIARIES FORM 10-Q For the Quarter Ended September 30, 1996 MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (Continued) Third Quarter and Nine Months Ended September 30, 1996 and 1995 Poor's and "A3" by Moody's. In an October 1996 press release, Standard & Poor's affirmed the Corporation's "A" senior debt rating and removed it from CreditWatch -- an action that was taken in March 1996 as a result of its then 81% ownership by Lockheed Martin. Standard & Poor's announced that the October rating action reflects the completion of Lockheed Martin's split-off of its ownership interest in the Corporation. While management believes its credit ratings will remain at an investment-grade level, no assurance can be given that these ratings will remain at the above-mentioned levels. The Corporation may repurchase up to 2.5 million shares of its common stock under authorizations from the Corporation's Board of Directors for use in the Amended Omnibus Securities Award Plan and for general corporate purposes. As of November 1, 1996, there have been 68,200 shares repurchased under these authorizations. OTHER MATTERS In connection with the Exchange Offer, the Corporation's Board of Directors adopted a shareholder rights plan that became effective, and certain terms of which were established, upon consummation of the split-off from Lockheed Martin. The shareholder rights plan provides, among other things, that if any person or group of persons becomes the beneficial owner of 15% or more of the Corporation's Common Stock, all holders of rights issued pursuant to the plan (other than such person or group of persons and their affiliates, associates and transferees) will have the right to acquire shares of the Corporation's Common Stock at 50% of the then current market value. Also in connection with the Exchange Offer, the Board of Directors adopted, and recommended that the shareholders of the Corporation approve at a special meeting called for such purpose, certain amendments to the Corporation's Articles of Incorporation. The amendments reduce the vulnerability of the Corporation to an unsolicited takeover proposal, particularly one that is made at an inadequate price or does not contemplate the acquisition of all of the Corporation's Common Stock. The special meeting of the shareholders to approve such amendments was held on September 27, 1996, and all amendments were approved as proposed. This Quarterly Report on Form 10-Q contains statements which, to the extent that they are not recitations of historical fact, constitute "forward looking statements" within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934.

SECTION 3.  ELIGIBILITY

     Awards may be granted only to exempt salaried Employees of the Corporation
or any Subsidiary who are designated from time to time by the Committee.

     No individual who beneficially owns Stock possessing five percent (5%) or
more of the combined voting power of all classes of stock of the Corporation
shall be eligible to participate in the Plan.

SECTION 4.  AWARDS

     The Committee may grant any of the following types of Awards, either
singly, in tandem or in combination with other Awards, as the Committee may in
its sole discretion determine:

     (a)  Non-qualified Stock Options.  A Non-qualified Stock Option is
          a right to purchase a specified number of shares of Stock during
          such specified time as the Committee may determine at a price not
          less than 100% of the Fair Market Value of the Stock on the date the
          option is granted.

          (i)  The purchase price of the Stock subject to the
               option may be paid in cash. At the discretion of the
               Committee, the purchase price may also be paid by the tender
               of Stock, or through a combination of Stock and cash, or
               through such other means as the Committee determines are
               consistent with the Plan's purpose and applicable law.  No
               fractional shares of Stock will be issued or accepted.
  
          (ii) Without limiting the foregoing, to the extent
               permitted by law (including relevant state law), the Committee
               may agree to accept, as full or partial payment of the
               purchase price of Stock issued upon exercise of options, (A) a
               promissory note of the optionee evidencing the optionee's
               obligation to make future cash payments to the Corporation, or
               (B) any other form of payment deemed acceptable to the
               Committee.  Promissory notes referred to in clause (A) above
               shall be payable as determined by the Committee (but in no
               event later than five years after the date thereof), shall be
               secured by a pledge of shares of Stock purchased, and shall
               bear interest at a rate established by the Committee.

     (b)  Incentive Stock Options.  An Incentive Stock Option is an
          Award in the form of an option to purchase Stock that complies with
          the requirements of Code Section 422 or any successor section.




                                      4

   5


          (i)  To the extent that the aggregate Fair Market                    
               Value (determined at the time of the grant of the Award) of     
               the shares subject to Incentive Stock Options which are         
               exercisable by one person for the first time during a           
               particular calendar year exceeds $100,000, such excess shall    
               be treated as Non-qualified Stock Options.  For purposes of     
               the preceding sentence, the term "Incentive Stock Option"       
               shall mean an option to purchase Stock that is granted          
               pursuant to this Section 4(b) or pursuant to any other plan of  
               the Corporation, which option is intended to comply with        
               Section 422(b) of the Code.                                     

          (ii) No Incentive Stock Option may be granted under this             
               Plan after the tenth anniversary of the date this Plan is       
               adopted, or the date this Plan is approved by the shareholders, 
               whichever is earlier, or be exercisable more than ten years     
               after the date the Award is made.                               

          (iii)The exercise price of any Incentive Stock Option               
               shall be no less than Fair Market Value of the Stock subject    
               to the option on the date the Award is made.                    
                                                                               
          (iv) The Committee may provide that the option price                 
               under an Incentive Stock Option may be paid by one or more of   
               the methods available for paying the option price of a          
               Non-qualified Stock Option.                                     

     (c)  Stock Appreciation Rights.  A Stock Appreciation Right               
          ("SAR") is a right to receive, upon exercise of the right, but       
          without payment by the Participant, an amount payable in cash.  The  
          amount payable with respect to each right shall be equal in value to 
          a percent of the excess, if any, of the Fair Market Value of a share 
          of Stock on the exercise date over the Fair Market Value of a share  
          of Stock on the date the Award was made (or, in the case of a right  
          granted with respect to a previously granted Award, the Fair Market  
          Value of the shares that are the subject of the previously granted   
          Award on the date such previous Award was granted).  The applicable  
          percent shall be established by the Committee.                       

      (d) Restricted Stock.  Restricted Stock is Stock of the                  
          Corporation that is issued to a Participant and is subject to        
          restrictions on transfer and/or such other restrictions or incidents 
          of ownership as the Committee may determine.                         
                                                                               
      (e) Other Stock-based Incentive Awards.  The Committee may from          
          time to time grant Awards under this Plan that provide the           
          Participant with the right to purchase Stock of the Corporation or   
          provide incentive Awards that are valued by reference to the Fair    
          Market Value of Stock of the Corporation (including, but not limited 
          to phantom securities or dividend equivalents).  Such Awards shall   
          be in a form determined by the Committee (and may include terms      
          contingent upon a                                                    
                                                                               
                                      5
                                                                               
                                                                               
   6
                                                                               
           change of control of the Corporation), provided that such Awards    
           shall not be inconsistent with the terms and purposes of the Plan.  

SECTION 5. SHARES OF STOCK AND OTHER STOCK-BASED AWARDS AVAILABLE UNDER PLAN

      (a)  Subject to the adjustment provisions of Section 9 hereof, the
           aggregate number of shares with respect to which Awards payable in
           securities may be granted under the Plan shall be no more than
           2,000,000 and the aggregate number of shares with respect to which
           Non-qualified Stock Options, Incentive Stock Options or SARs may be
           granted to any individual Participant shall be no more than 200,000
           in any one year.  Awards that are cancelled or repriced shall be
           counted against the 200,000 share per year limit to the extent
           required by Section 162(m) of the Code.

      (b)  Any unexercised or undistributed portion of any terminated or
           forfeited Award (other than an Award terminated or forfeited by
           reason of the exercise of any Award granted in tandem therewith)
           shall be available for further Awards in addition to those available
           under Section 5(a) hereof.

      (c)  For the purposes of computing the aggregate number of shares
           with respect to which awards payable in securities may be granted
           under the Plan, the following rules shall apply:

           (i)  except as provided in (v) of this Section, each               
                option shall be deemed to be the equivalent of the maximum    
                number of shares that may be issued upon exercise of the      
                particular option;                                            
                                                                              
           (ii) except as provided in (v) of this Section, each               
                other stock-based Award shall be deemed to be equal to the    
                number of shares to which it relates;                         

          (iii) except as provided in (v) of this Section, where the
                number of shares available under the Award is variable on the
                date it is granted, the number of shares shall be deemed to be
                the maximum number of shares that could be received under that
                particular Award.

           (iv) where one or more types of Awards (both of which
                are payable in Stock or another security) are granted in
                tandem with each other, such that the exercise of one type of
                Award with respect to a number of shares cancels an equal
                number of shares of the other, each joint Award shall be
                deemed to be the equivalent of the number of shares under the
                other; and


                                      6


   7


           (v)  each share awarded or deemed to be awarded under
                the preceding subsections shall be treated as shares of Stock,
                even if the Award is for a security other than Stock.

           Additional rules for determining the aggregate number of shares
           with respect to which awards payable in securities may be granted
           under the Plan may be made by the Committee, as it deems necessary
           or appropriate.

      (d)  No Stock may be issued pursuant to an Award under the Plan
           except to the extent that, prior to such issuance, the Corporation
           shall have acquired shares from its shareholders sufficient to
           fulfill the requirements of the Plan with respect to such issuance.

SECTION 6. AWARD AGREEMENTS

     Each Award under this Plan shall be evidenced by an Award Agreement
setting forth the number of shares of Stock, SARs, or units subject to the
Award and such other terms and conditions applicable to the Award as determined
by the Committee.

      (a)  Award Agreements shall include the following terms:

           (i)  Non-assignability:  A provision that no Award
                shall be assignable or transferable except by will or by the
                laws of descent and distribution and that during the lifetime
                of a Participant, the Award shall be exercised only by such
                Participant or by his or her guardian or legal representative.

           (ii) Termination of Employment:  A provision
                describing the treatment of an Award in the event of the
                retirement, disability, death or other termination of a
                Participant's employment with the Corporation or Subsidiary,
                including but not limited to terms relating to the vesting,
                time for exercise, forfeiture or cancellation of an Award in
                such circumstances.

           (iii)Rights as Shareholder:  A provision that a
                Participant shall have no rights as a shareholder with respect
                to any securities covered by an Award until the date the
                Participant becomes the holder of record.  Except as provided
                in Section 9 hereof, no adjustment shall be made for dividends
                or other rights, unless the Award Agreement specifically
                requires such adjustment, in which case, grants of dividend
                equivalents or similar rights shall not be considered to be a
                grant of any other shareholder right.

           (iv) Withholding:  A provision requiring the withholding of
                applicable taxes required by law from all amounts paid in
                satisfaction of an Award.  In the case of an Award paid in
                cash, the withholding obligation shall be satisfied

                                      7


   8

                 by withholding the applicable amount and paying the net       
                 amount in cash to the Participant.  In the case of Awards     
                 paid in shares of Stock or other securities of the            
                 Corporation, a Participant may satisfy the withholding        
                 obligation by paying the amount of any taxes in cash or, with 
                 the approval of the Committee, shares of Stock or other       
                 securities may be deducted from the payment to satisfy the    
                 obligation in full or in part.  The number of shares to be    
                 deducted shall be determined by reference to the Fair Market  
                 Value of such shares on the date the Award is exercised.      


            (v)  Execution:  A provision stating that no Award is
                 enforceable until the Award Agreement or a receipt has been
                 signed by the Participant and the Chairman or the Chief
                 Executive Officer of the Corporation (or his delegate).  By
                 executing the Award Agreement or receipt, a Participant shall
                 be deemed to have accepted and consented to any action taken
                 under the Plan by the Committee, the Board of Directors or
                 their delegates.

            (vi) Holding Period:  In the case of an Award to an
                 Insider, (A)  of an equity security, a provision stating (or
                 the effect of which is to require) that such security must be
                 held for at least six months (or such longer period as the
                 Committee in its discretion specifies) from the date of
                 acquisition; or (B)  of a derivative security with a fixed
                 exercise price within the meaning of Section 16, a provision
                 stating (or the effect of which is to require) that at least
                 six months (or such longer period as the Committee in its
                 discretion specifies) must elapse from the date of acquisition
                 of the derivative security to the date of disposition of the
                 derivative security (other than upon exercise or conversion)
                 or its underlying equity security; or (C) of a derivative
                 security without a fixed exercise price within the meaning of
                 Section 16, a provision stating (or the effect of which is to
                 require) that at least six months (or such longer period as
                 the Committee in its discretion specifies) must elapse from
                 the date upon which such price is fixed to the date of
                 disposition of the derivative security (other than by exercise
                 or conversion) or its underlying equity security; provided,
                 however, that this clause (vi) shall not apply to any Award
                 granted on or after August 15, 1996.

            (vii) Exercise and Payment:  The permitted methods of
                 exercising and paying the exercise price with respect to the
                 Award.

      (b)   Award Agreements may include the following terms:

            (i)  Replacement, Substitution and Reloading:  Any
                 provisions (A)  permitting the surrender of outstanding Awards
                 or securities held by the Participant in order to exercise or
                 realize rights under other Awards, or in exchange

                                      8


   9

                 for the grant of new Awards under similar or different terms  
                 (including the grant of reload options), or, (B) requiring   
                 holders of Awards to surrender outstanding Awards as a        
                 condition precedent to the grant of new Awards under the      
                 Plan.                                                         

            (ii) Other Terms:  Such other terms as are necessary and
                 appropriate to effect an Award to the Participant including
                 but not limited to the term of the Award, vesting provisions,
                 any requirements for continued employment with the Corporation
                 or any Subsidiary, any other restrictions or conditions
                 (including performance requirements) on the Award and the
                 method by which restrictions or conditions lapse, the effect
                 on the Award of a change in control, the price and the amount
                 or value of Awards.

SECTION 7.  AMENDMENT AND TERMINATION

     The Board of Directors may at any time amend, suspend or discontinue the
Plan.  The Committee may at any time alter or amend any or all Award Agreements
under the Plan to the extent permitted by law.  However, no such action may,
without approval of the shareholders of the Corporation, be effective if
shareholder approval would be required to keep the Plan and the Awards made
thereunder in compliance with Rule 16b-3 and Section 162(m).

SECTION 8.  ADMINISTRATION

       (a)  The Plan and all Awards granted pursuant thereto shall be           
            administered by the  Committee.  The members of the Committee shall 
            be designated by the Board of Directors.  A majority of the members 
            of the Committee shall constitute a quorum.  The vote of a majority 
            of a quorum shall constitute action by the Committee.               
                                                                                
       (b)  The Committee shall periodically determine the Participants         
            in the Plan and the nature, amount, pricing, timing, and other
            terms of Awards to be made to such individuals.
                                                                                
       (c)  The Committee shall have the power to interpret and administer the
            Plan.  All questions of interpretation with respect to the Plan,
            the number of shares of Stock, SARs, or units granted, and the
            terms of any Award Agreements shall be determined by the    
            Committee and its determination shall be final and conclusive upon  
            all parties in interest.  In the event of any conflict between an
            Award Agreement and this Plan, the terms of this Plan shall govern. 
                                                                                
       (d)  It is the intent of the Corporation that this Plan and Awards       
            hereunder satisfy and be interpreted in a manner, that, in the case 
            of Participants who are or may be Insiders, satisfies the applicable
            requirements of Rule 16b-3, so that such persons                    

                                      9


   10

            will be entitled to the benefits of Rule 16b-3 or other exemptive
            rules under Section 16 and will not be subjected to avoidable
            liability thereunder.  If any provision of this Plan or of any
            Award would otherwise frustrate or conflict with the intent
            expressed in this Section 8(d), that provision to the extent
            possible shall be interpreted and deemed amended so as to avoid
            such conflict.  To the extent of any remaining irreconcilable
            conflict with such intent, the provision shall be deemed void as
            applicable to Insiders to the extent permitted by law and deemed
            advisable by the Committee.

       (e)  It is the intent of the Corporation that this Plan and Awards       
            hereunder satisfy and be interpreted in a manner, that, in the case 
            of Participants who are or may be Covered Employees, satisfies the  
            applicable requirements of Section 162(m), so that the Corporation  
            will be entitled, to the extent possible, to deduct compensation    
            paid under the Plan and otherwise to such Covered Employees and will
            not be subjected to avoidable loss of deductions thereunder.  If any
            provision of this Plan or of any Award would otherwise frustrate or 
            conflict with the intent expressed in this Section 8(e), that       
            provision to the extent possible shall be interpreted and deemed    
            amended so as to avoid such conflict.  To the extent of any         
            remaining irreconcilable conflict with such intent, the provision   
            shall be deemed void as applicable to Covered Employees to the      
            extent permitted by law and deemed advisable by the Committee.      
                                                                                
       (f)  The Committee may delegate to the officers or employees of          
            the Corporation the authority to execute and deliver such           
            instruments and documents, to do all such acts and things, and to   
            take all such other steps deemed necessary, advisable or convenient 
            for the effective administration of the Plan in accordance with its 
            terms and purpose, except that the Committee may not delegate any   
            discretionary authority with respect to substantive decisions or    
            functions regarding the Plan or Awards thereunder as these relate to
            Insiders or Covered Employees, including but not limited to         
            decisions regarding the timing, eligibility, pricing, amount or     
            other material term of such Awards.                                 

SECTION 9.  ADJUSTMENT PROVISIONS

       (a)  In the event of any change in the outstanding shares of Stock
            by reason of a stock dividend or split, recapitalization, merger or 
            consolidation, reorganization, combination or exchange of shares or 
            other similar corporate change, the number of shares of Stock (or   
            other securities) then remaining subject to this Plan, and the      
            maximum number of shares that may be issued to anyone pursuant to   
            this Plan, including those that are then covered by outstanding     
            Awards, shall (i)  in the event of an increase in the number of     
            outstanding shares, be proportionately increased and the price for  
            each share then covered by an outstanding Award shall be            
            proportionately reduced, and (ii) in the event of a reduction in the
            number of

            each share then covered by an outstanding Award, shall be
            proportionately increased.

       (b)  The Committee shall make any further adjustments as it deems
            necessary to ensure equitable treatment of any holder of an Award as
            the result of any transaction affecting the securities subject to
            the Plan not described in (a), or as is required or authorized under
            the terms of any applicable Award Agreement.

SECTION 10. CHANGE IN CONTROL

       (a)  In addition to its authority under, and subject to, Section
            5, 7 and 9, in the event of a change in control of the Corporation,
            in addition to any action required or authorized by the terms of any
            Award Agreement, the Committee may, in its discretion, take any of
            the following actions as a result of, or in anticipation of, any
            such event to assure fair and equitable treatment of Participants:

            (i)  accelerate time periods for purposes of vesting
                 in, or realizing gain from, any outstanding Award made
                 pursuant to this Plan;

            (ii) cancel any outstanding Award made pursuant to this Plan and
                 pay to the holder thereof its equivalent cash value, as
                 determined by the Committee based upon the highest price per
                 share of Stock received or to be received by other
                 shareholders of the Corporation in the Change in Control, as
                 of the date of the Change in Control; or

           (iii) make other adjustments or modifications to outstanding Awards
                 as the Committee deems appropriate to maintain and protect the
                 rights and interests of Participants   following such Change
                 in Control.

            Any such action approved by the Committee shall be conclusive and
            binding on the Corporation and all Participants.

       (b)  For the purposes of this Section, a "Change in Control" shall
            mean on or after the effective date of the Plan,

            (i)  The acquisition by any individual, entity or group

                Affiliate of the Corporation, or (3) any acquisition by any   
                entity pursuant to a transaction which complies with clauses

          (ii)  Individuals who constitute the Board on the effective date of

                constitute at least a majority of the Board; provided, however,
                that any individual becoming a director subsequent to such
                effective date whose election, or nomination for election by
                the Corporation's shareholders, was approved by a vote of at
                least a majority of the directors then comprising the Incumbent
                Board shall be considered as though such individual were a
                member of the Incumbent Board, but excluding, for this purpose,
                any such individual whose initial assumption of office occurs
                as a result of an actual or threatened election contest with
                respect to the election or removal of directors or other actual
                or threatened solicitation of proxies or consents by or on

                voting power of the then outstanding voting securities entitled
                to vote generally in the election of directors, as the case may
                be, of the corporation resulting from such Business Combination
                (including, without limitation, a corporation which as a result
                of such transaction owns the Corporation or all or

                respectively, the fully diluted shares of common stock of the  
                corporation resulting from such Business Combination, as       
                reflected on such corporation's financial statements, or the   
                combined voting power of the then outstanding voting           
                securities of such corporation except to the extent that such

any applicable waiting period).  If the Company does not maintain a long-term
disability program, or if a Participant does not elect coverage under such
program, Disability shall mean the incapacity of the Participant such that he

consecutive days, as determined in the reasonable judgment of the Committee.

     1.11 "Exchange Act" shall mean the Securities Exchange Act of 1934, as

Stock on the relevant date or, if no sale was made on such date, then on the

listed on the New York Stock Exchange ("NYSE"), as reported in the Wall Street
Journal or (b) if the Common Stock is not listed on the NYSE but is listed on
the NASDAQ National Market System, then as reported on such system, or (c) if

System, as determined by the Board of Directors or Committee.

Years or any other period selected and established by the Committee at the time
the corresponding Awards are granted.

an Award in accordance with Article 2 which Award has neither been fully paid
out nor expired.

     1.16 "Retirement" shall mean Participant's termination of employment with
the Company (a) at a time at which the Participant is entitled to immediately
commence receipt of

   5

benefits from the Company's qualified defined benefit retirement plan or (b) if
the Company does not maintain such a plan at the time, either (i) at or after

any and all regulations promulgated by the Internal Revenue Service thereunder,
as the same may be amended, modified, superseded or replaced from time to time.

ARTICLE 2 - ELIGIBILITY

     All key employees of the Company and any of its direct or indirect
subsidiaries, including officers whether or not members of the Board of
Directors, are eligible for the grant of Awards. The selection of key employees
to receive Awards will be within the discretion of the Committee.

ARTICLE 3 - COMMON STOCK AVAILABLE FOR AWARDS; ADJUSTMENT

     3.1 Number of Shares of Common Stock.  Subject to adjustment as provided
for in Section 3.3, the aggregate number of shares of Common Stock that may be
subject to Awards granted under this Plan shall be 250,000 shares of Common
Stock.  The assumption of awards granted by an organization acquired by the
Company, or the grant of Awards under this Plan in substitution of any such
awards, will not reduce the number of shares of Common Stock available for the
grant of Awards under this Plan.

     Common Stock subject to an Award that expires or is forfeited, terminated,
or canceled will again be available for grant under this Plan, without reducing
the number of shares of Common Stock available for grant of Awards under this
Plan.

     3.2 No Fractional Shares.  No fractional shares of Common Stock will be
issued under the Plan, and the Committee will round the number of shares to
which a Participant is entitled down to the nearest whole share.



                                      5

   6

     3.3 Adjustment.  The aggregate number of shares of Common Stock which may
be issued pursuant to Awards granted hereunder, the number of shares of Common
Stock covered by each outstanding Award and the price per share thereof shall
be appropriately adjusted for any increase or decrease in the number of
outstanding shares of Common Stock resulting from a stock split or other
subdivision or consolidation of shares of Common Stock or for other capital
adjustments or payments of stock dividends or distributions or other increases
or decreases in the outstanding shares of Common Stock without receipt of
consideration by the Company.

     In the event of any change in the outstanding shares of Common Stock by
reason of any recapitalization, merger, consolidation, spin-off, combination or
exchange of shares or other corporate change, or any distributions to common
shareholders other than cash dividends, the Committee shall make such
substitution or adjustment, if any, as it deems to be equitable, as to the
number or kind of shares of Common Stock or other securities issued or reserved
for issuance pursuant to the Plan, and the number or kind of shares of Common
Stock or other securities covered by outstanding Awards, and the price thereof.
In instances where another corporation or other business entity is being
acquired by the Company, and the Company has assumed outstanding employee award
grants and/or the obligation to make future or potential grants under a prior
existing plan of the acquired entity, similar adjustments are permitted at the
discretion of the Committee.  The adjustments provided for in this Section 3.3,
and the manner of their application, shall be determined by the Committee in
its sole discretion.

ARTICLE 4 - ADMINISTRATION

     4.1 Committee.  This Plan will be administered by the Committee.  The
Committee will, subject to the terms of this Plan, have the authority to (a)
select the eligible employees who will receive Awards, (b) grant Awards, (c)
determine the number of Awards to be granted to Participants, (d) determine the
terms, conditions, and restrictions applicable to Awards (including the
establishment of Performance Goals pursuant to Section 5.3), (e) adopt, alter,
and repeal administrative rules and practices governing this Plan, (f)
interpret the terms and provisions of this Plan and any Awards granted under
this Plan, (g) prescribe the forms of any Award Agreement, or other instruments
relating to Awards, and (h) otherwise supervise the administration of this 


                                      6

   7

Plan and exercise such rights and responsibilities as are delegated to it
thereunder.  All decisions by the Committee will be made with the approval of
not less than a majority of its members.                                   

     4.2 Delegation.  The Committee may delegate any of its authority to any
other person or persons that it deems appropriate, provided the delegation does
not cause this Plan or any Awards granted under this Plan to fail to qualify
for the exemption provided by Rule 16b-3 or Section 162(m).

     4.3 Decisions Final.  All decisions by the Committee, and by any other
person or persons to whom the Committee has delegated authority, will be final
and binding on all persons.

ARTICLE 5 - AWARDS

     5.1 General.  The Committee may, in its discretion, grant to Participants
Awards valued by reference to shares of Common Stock that are wholly contingent
on the attainment of performance goals established by the Committee in
accordance with the terms of this Plan.

     5.2 Grant of Awards.  (a) Awards shall be granted to Participants as of
the beginning of a Measurement Period.  The payment with respect to the Awards
shall be conditioned on the satisfaction of the performance goals described in
Section 5.3 at the end of the applicable Measurement Period.  Once established,
the Committee shall not have discretion to modify the terms of the Awards
except with respect to any discretion specifically granted to the Committee
under this Plan.  It is intended that all payments hereunder to Participants
will satisfy the requirements for the exemption under Section 162(m) and
related regulations for "qualified performance-based compensation."

     (b) Not later than 90 days after the beginning of the Measurement Period
(or, if earlier, the date on which 25% of the Measurement Period has elapsed),
the Committee shall grant a specified number of Awards to each Participant with
respect to that Measurement Period.  No Participant may be granted Awards with
respect to a Measurement Period having as a target amount in excess of the
lesser of (i) an aggregate of 20,000 shares of Common Stock or (ii) a dollar
value of $500,000 based on the Fair Market Value of the target number of shares
of Common Stock 



                                      7

   8

subject thereto on the first day of the applicable Measurement Period.         

     (c) At the end of the Measurement Period, the Committee shall determine
the percentage, if any, of the Awards granted to the Participant for that
Measurement Period that are earned by the Participant.  That percentage shall
be based on the degree to which the performance goals for that Measurement
Period are satisfied.  The formula for determining the correlation between the
percentage of the Awards earned and the level of performance for a Measurement
Period shall be established in writing by the Committee at the time the
performance goals are determined.  Prior to the payment of any Awards, the
Committee must certify in writing the degree of attainment of the applicable
performance goals.

     5.3 Performance Goals.  Performance goals used to compute Awards shall be
adopted by the Committee in writing prior to the grant of any Awards to which
such performance goals apply.  The performance goals shall be based on one or
more of the following performance measures:  (a) total return to shareholders,
(b) cash flow, (c) return on equity, (d) return on assets, (e) stock price, and
(f) earnings per share.  Any such performance goals and the applicable
performance measures will be reflected in each Award Agreement to which such
goals and measures relate.  The number of Awards that will be paid out to any
Participant at the end of the applicable Measurement Period will depend on the
extent to which the Company attains the established performance goals, as
established pursuant to Section 5.2(c).

     5.4 Nonforfeitability of the Award.  (a)  General.  Except as provided in
Section 5.4(b) and (c) and Article 6, a Participant must remain employed by the
Company until the end of a Measurement Period to receive payment with respect
to any Award.

     (b) Death or Disability.  Subject to Section 5.4(d), if during a
Measurement Period a Participant terminates employment on account of death or
Disability, (together, a "Qualifying Termination"), such Participant (or in the
case of death, his estate) shall be entitled to a prorated payment with respect
to Awards held by the Participant with respect to that Measurement Period, as
described in the next sentence.  The Participant shall be entitled to payment
with respect to a percentage of such 



                                      8

   9

Awards as set forth below based on the Fiscal Year during the Measurement
Period in which his Qualifying Termination occurs:


FISCAL YEAR PERCENTAGE ----------- ---------- 1st 0% 2nd 33-1/3% 3rd 66-2/3%
For purposes of determining the payment with respect to a Participant's Awards under this Section 5.4(b), it shall be assumed that the Company has achieved the target level of performance it established for the Measurement Period. If the Measurement Period is other than three Fiscal Years, then the Committee shall make appropriate adjustments to the above schedule in its sole discretion. Payment with respect to Awards under this Section 5.4(b), if any, will be made as soon as practicable after the Participant's Qualifying Termination occurs. (c) Retirement and Certain Terminations. Subject to Section 5.4(d), if a Participant holding Awards terminates employment on account of Retirement, or is involuntarily terminated by the Company without Cause before the end of the applicable Measurement Period, the Participant shall be entitled to payment with respect to such Awards at the end of such Measurement Period as if he had remained employed until that time. (d) Committee Negative Discretion. The Committee may, in its sole discretion, decide to reduce or eliminate any amount otherwise payable with respect to an Award under Section 5.4(b) or (c). 5.5 Payment of the Award. A Participant's Award shall be paid as soon as practicable after the end of the Measurement Period (or, in the case of a Participant who dies or incurs a Disability and becomes entitled to payment with respect to an Award pursuant to Section 5.4(b), as soon as practicable following death or the determination of Disability). Payment shall be made in shares of Common Stock or, in the discretion of the Committee, all or in part cash, based on the Fair Market Value of the applicable number of shares of Common Stock on the payment date. 9 10 ARTICLE 6 - CHANGE OF CONTROL 6.1 Effect of Change of Control. Notwithstanding any provision of this Plan to the contrary, in the event that a Change of Control occurs, all conditions applicable to outstanding Awards will be deemed to have been satisfied at the target level as of the date of the Change of Control. Payment with respect to such Awards shall be made as soon as practicable after the Change of Control in accordance with the last sentence of Section 5.5. ARTICLE 7 - GENERAL 7.1 Nonassignability of Awards. No right or interest of a Participant under the Plan shall be subject in any manner to anticipation, alienation, sale, assignment, transfer, encumbrance, pledge, attachment, garnishment by creditors of the Participant or his successors, or shall be transferable by a Participant otherwise than by will or the laws of intestate succession. Any attempt to take an action with respect to an Award which is prohibited by the preceding sentence shall render such Award null and void. 7.2 No Right or Obligation of Continued Employment. Nothing contained in this Plan shall require the Company or a related company to continue to employ a Participant, nor shall the Participant be required to remain in the employment of the Company or a related company. 7.3 Withholding. The Company shall withhold all required local, state and federal taxes from any amount payable in respect of an Award, including withholding of shares of Common Stock otherwise payable pursuant to the Plan. 7.4 Effective Date. This Plan shall be effective as of the latest to occur of (a) approval by the Company's shareholders and (b) the distribution by Lockheed Martin Corporation of such number of shares of Common Stock which results in Lockheed Martin Corporation no longer owning, directly or indirectly, more than fifteen percent (15%) of the outstanding Common Stock (the "Split-Off"). If both of the above conditions do not occur by December 31, 1997, all Awards previously granted shall become null and void. Moreover, no payment shall be made to a Participant pursuant to an Award prior to such shareholder 10 11 approval being obtained and the Split-Off having occurred. This Section 7.4 shall supersede any other provision of the Plan. 7.5 Amendment and Termination of the Plan. The Plan may be amended or terminated at any time by the Board of Directors or by the Committee as delegated by the Board of Directors, provided that such termination or amendment shall not, without the consent of the Participant, adversely affect such Participant's rights with respect to Awards previously awarded to him. Shareholder approval for any amendment is required to the extent necessary to preserve the exemption for "qualified performance-based compensation" under Section 162(m). With the consent of the Participant affected, the Board of Directors, or by delegation of authority by the Board of Directors, the Committee, may amend outstanding Award Agreements in a manner not inconsistent with the Plan. 7.6 Binding on Successors. The obligations of the Company under the Plan shall be binding upon any organization which shall succeed to all or substantially all of the assets of the Company, or into which the Company may merge, and the term "Company," whenever used in the Plan, shall mean and include any such organization after the succession. 7.7 References. Any masculine personal pronoun shall be considered to mean also the corresponding feminine or neuter personal pronoun, as the context requires. 7.8 Applicable Law. The Plan shall be governed by and construed in accordance with the laws of the State of North Carolina. 11 12 IN WITNESS WHEREOF, the Martin Marietta Materials, Inc. Performance Share Plan is, by the authority of the Board of Directors of the Corporation, executed as of the 21st day of October, 1996. MARTIN MARIETTA MATERIALS, INC. By: /s/ Stephen P.

                        EMPLOYMENT PROTECTION AGREEMENT


     THIS AGREEMENT, between Martin Marietta Materials, Inc., a North Carolina

                             W I T N E S S E T H :

     WHEREAS, Employee is a valuable member of management of the Company and
the Company desires to ensure the continuity of its senior management; and

     WHEREAS, it is the determination of the Company that management continuity
is most likely to occur if senior management is financially protected against
involuntary termination following a "Change of Control" (as defined below) of
the Company; and

     WHEREAS, the Company and the Employee have agreed to enter into this
Agreement to provide the Employee with payments and benefits upon certain
terminations of the Employee's employment with the Company in connection with a
Change of Control, in consideration of the Employee's continued service to the
Company (which the parties hereto agree constitutes adequate consideration to
support to the Company's obligations under this Agreement);

     NOW, THEREFORE, in consideration of the premises and mutual covenants
herein contained, it is hereby agreed by and between the Company and the
Employee as follows:

     1. Definitions.  For purposes of this Agreement,

shall be considered "willful" unless done, or omitted to be done, by him not in
good faith and without reasonable belief that his action or omission was in the
best interest of the Company.  The Employee shall not be deemed to have been
terminated for Cause, unless the Company shall have given the Employee (A)
notice setting forth, in reasonable detail, the facts and circumstances claimed
to provide a basis for termination for Cause, (B) a reasonable opportunity for
the Employee, together with his counsel, to be heard before the Board and (C) a

plan (or related trust) sponsored or maintained by the Company or any Affiliate
of the Company or (Z) any acquisition by any entity pursuant to a transaction
which complies with clauses (A), (B) and (C) of subsection (iii) of this
definition; or

             (ii)  Individuals who constitute the Board as of October 18, 1996

and entities who were the beneficial owners, respectively, of the Outstanding
Company Common Stock and Outstanding Company Voting Securities immediately
prior to such Business Combination beneficially own, directly or indirectly,
more than 50% of, respectively, the then outstanding shares of common stock and
the combined voting power of the then outstanding voting securities entitled to
vote generally in the election of directors, as the case may be, of the
corporation resulting from such Business Combination (including, without
limitation, a corporation which as a result of such transaction owns the

through one or more subsidiaries) in substantially the same proportions as
their ownership, immediately prior to such Business Combination, of the
Outstanding Company Common Stock and Outstanding Company Voting Securities, as
the case may be, and (B) no Person (excluding any employee benefit plan (or
related trust) sponsored or maintained by the Company or any Affiliate of the

impairment which qualifies the Employee for benefits under the Company's
long-term disability program.  An Employee shall not be deemed to have incurred
a Disability until such benefits actually become payable (i.e., after any
applicable waiting period).  If the Company does not maintain a long-term
disability program, or if the Employee does not elect coverage under such
program, Disability shall mean the incapacity of the Employee such that he is

ability to carry out his duties and responsibilities with the Company or (B)
has failed to take any action where such failure results in material and
adverse changes in the Employee's position (including titles), authority or
responsibilities with the Company or reduces the Employee's ability to carry

its employees pursuant to an "employee welfare benefit plan" as defined in
Section 3(1) of the Employee Retirement Income Security Act of 1974, as
amended.

     2. Effective Date; Term.  This Agreement shall be effective as of the
Effective Date, and shall remain in effect for three (3) years following the
Effective Date, after which time this Agreement shall expire; provided,
however, that on the third anniversary of the Effective Date, and on each
subsequent anniversary thereof (each an "Anniversary Date"), the Term of
this Agreement shall automatically be extended for one additional year, unless
at least sixty (60) days prior to such Anniversary Date, either party to this
Agreement gives written notice to the other party of an intent to cancel such
automatic extension, in which case this Agreement shall expire upon the
expiration of the then existing Term; further provided, however, that,
notwithstanding the above, (a) if a Change of Control occurs prior to the
termination of this Agreement, or (b) if prior to the termination of this
Agreement the Board becomes aware of any circumstances which in the ordinary
course result in a Change of Control (whether or not with respect to the party
first coming to the Board's attention), then under no circumstances will this
Agreement terminate prior to the date that is 31 days following the second
anniversary of the Change of Control.  Notwithstanding this Section 2, the
Company's obligations under this Agreement shall survive the termination of
this Agreement if all events giving rise to such obligations occurred prior to
such termination.

     3. Obligations of the Company upon Termination. If, during the two year
period following the effective date of a Change of Control, the Company
terminates the Employee's 


                                       5

   6


employment other than for Cause or Disability, or the Employee terminates his
employment for Good Reason or if, during the thirty day period following the
two year anniversary of the effective date of a Change of Control, the Employee
terminates his employment for any reason:

     (a)  the Company shall pay to the Employee in a lump sum within 15 days
following Employee's termination of employment:

                  (i)  if not theretofore paid, an amount equal to any portion
                  of the Employee's earned but unpaid Base Salary (including
                  unused but accrued vacation time) through the date of
                  termination of employment; and

                  (ii) a cash amount equal to twice the sum of:

                        (A) the Employee's annual Base Salary and

                        (B) the Employee's Annual Bonus.

     (b)  the Company shall provide, for the period of two years following the
date of Employee's termination of employment, all Welfare Benefits for the
Employee and his dependents and beneficiaries that are at least as favorable in
all material respects as the benefits provided to such person immediately
preceding the Change of Control and to employees employed by the Company or its
successor in positions following the Change of Control that are similar to the
position the Employee held immediately prior to the Change of Control
("Similarly Situated Active Employees"); provided, however, that, with respect
to this Section 3(b), the Employee shall be required to pay the same share of
the cost of such Welfare Benefits as Similarly Situated Active Employees.

     4. Certain Additional Payments by the Company

     (a) Anything in this Agreement to the contrary notwithstanding, in the
event it shall be determined that any payment or distribution by the Company to
or for the benefit of the Employee, or any benefit provided by the Company to
the Employee (whether paid or payable or distributed or distributable provided
pursuant to the terms of this Agreement or otherwise, but determined without
regard to any additional payments required 


                                       6

   7

under this Section 4) (a "Payment") would be subject to the excise tax imposed
by Section 4999 of the Code (or any successor provision) or any interest or
penalties are incurred by the Employee with respect to such excise tax (such
excise tax, together with any such interest and penalties, are hereinafter
collectively referred to as the "Excise Tax"), then the Employee shall be
entitled to receive an additional payment (a "Gross-Up Payment") in an amount
such that after payment by the Employee of all taxes with respect to the
Gross-Up Payment (including any interest or penalties imposed with respect to
such taxes), including, without limitation, any income taxes (and any interest
and penalties imposed with respect thereto) and Excise Tax imposed upon the
Gross-Up Payment, the Employee retains an amount of the Gross-Up Payment equal
to the Excise Tax imposed upon the Payment.

     (b) Subject to the provisions of Section 4(c), all determinations required
to be made under this Section 4, including whether and when a Gross-Up Payment
is required and the amount of such Gross-Up Payment and the assumptions to be
utilized in arriving at such determination, shall be made by Ernst & Young or
such other nationally recognized accounting firm then auditing the accounts of
the Company (the "Accounting Firm") which shall provide detailed supporting
calculations both to the Company and the Employee within 15 business days of
the receipt of notice from the Employee that there has been a Payment, or such
earlier time as is requested by the Company.  In the event that the Accounting
Firm is serving as accountant or auditor for the individual, entity or group
effecting the Change of Control, or is unwilling or unable to perform its
obligations pursuant to this Section 4, the Employee shall appoint another
nationally recognized accounting firm to make the determinations required
hereunder (which accounting firm shall then be referred to as the Accounting
Firm hereunder).  All fees and expenses of the Accounting Firm shall be borne
solely by the Company.  Any Gross-Up Payment, determined pursuant to this
Section 4, shall be paid by the Company to the Employee within five days of the
receipt of the Accounting Firm's determination.  Any determination by the
Accounting Firm shall be binding upon the Company and the Employee.  As a
result of the potential uncertainty in the application of Section 4999 of the
Code (or any successor provision) at the time of the initial determination by
the Accounting Firm hereunder, it is possible that Gross-Up Payments which will
not have been made by the Company should have been made ("Underpayment"),
consistent with the calculations required 


                                       7

   8


to be made hereunder.  In the event that the Company exhausts its remedies
pursuant to Section 4(c) and the Employee thereafter is required to make a
payment of any Excise Tax, the Accounting Firm shall determine the amount of
the Underpayment that has occurred and any such Underpayment shall be promptly
paid by the Company to or for the benefit of the Employee.

     (c) The Employee shall notify the Company in writing of any claim by the
IRS that, if successful, would require the payment by the Company of the
Gross-Up Payment.  Such notification shall be given as soon as practicable but
no later than 20 business days after the Employee is informed in writing of
such claim and shall apprise the Company of the nature of such claim and the
date on which such claim is requested to be paid.  The Employee shall not pay
such claim prior to the expiration of the 30-day period following the date on
which he gives such notice to the Company (or such shorter period ending on the
date that any payment of taxes with respect to such claim is due).  If the
Company notifies the Employee in writing prior to the expiration of such period
that it desires to contest such claim, the Employee shall:

                  (i)  give the Company any information
                       reasonably requested by the Company relating to such
                       claim,

                  (ii) take such action in connection with
                       contesting such claim as the Company shall reasonably
                       request in writing from time to time, including, without
                       limitation, accepting legal representation with respect
                       to such claim by an attorney reasonably selected by the
                       Company,

                  (iii) cooperate with the Company in good
                       faith in order effectively to contest such claim, and
                                          
                  (iv) permit the Company to participate in
                       any proceedings relating to such claim;

provided, however, that the Company shall bear and pay directly all costs and
expenses (including additional interest and penalties) incurred in connection
with such contest and shall indemnify and hold the Employee harmless, on an
after-tax basis, for any Excise Tax or income tax (including interest and


                                       8


   9

penalties with respect thereto) imposed as a result of such representation and
payment of costs and expenses.  Without limiting the foregoing provisions of
this Section 4(c), the Company shall control all proceedings taken in
connection with such contest and, at its sole option, may pursue or forgo any
and all administrative appeals, proceedings, hearings and conferences with the
taxing authority in respect of such claim and may, at its sole option, either
direct the Employee to pay the tax claimed and sue for a refund or contest the
claim in any permissible manner, and the Employee agrees to prosecute such
contest to a determination before any administrative tribunal, in a court of
initial jurisdiction and in one or more appellate courts, as the Company shall
determine; provided, however, that if the Company directs the Employee to pay
such claim and sue for a refund, the Company shall advance the amount of such
payment to the Employee, on an interest-free basis, and shall indemnify and
hold the Employee harmless, on an after-tax basis, from any Excise Tax or
income tax (including interest or penalties with respect thereto) imposed with
respect to such advance or with respect to any imputed income with respect to
such advance; and further provided that any extension of the statute of
limitations relating to payment of taxes for the taxable year of the Employee
with respect to which such contested amount is claimed to be due is limited
solely to such contested amount.  Furthermore, the Company's control of the
contest shall be limited to issues with respect to which a Gross-Up Payment
would be payable hereunder and the Employee shall be entitled to settle or
contest, as the case may be, any other issue raised by the IRS or any other
taxing authority.

        (d) If, after the receipt by the Employee of an amount advanced by the
Company pursuant to Section 4(c), the Employee becomes entitled to receive any
refund with respect to such claim, the Employee shall (subject to the Company's
complying with the requirements of Section 4(c)) promptly pay to the Company
the amount of such refund (together with any interest paid or credited thereon
after taxes applicable thereto).  If, after the receipt by the Employee of an
amount advanced by the Company pursuant to Section 4(c), a determination is
made that the Employee shall not be entitled to any refund with respect to such
claim and the Company does not notify the Employee in writing of its intent to
contest such denial of refund prior to the expiration of 30 days after such
determination, then such advance shall be forgiven and shall not be required to
be repaid 





                                      9


   10

and the amount of such advance shall offset, to the extent thereof, the amount
of Gross-Up Payment required to be paid.

     5. Other Compensation and Benefits.  The amount payable under this
Agreement in accordance with Section 3(a) shall not be reduced on account of
any compensation received by the Employee from other employment.  From and
after the date the Employee is employed by a third party which provides any of
the benefits described in Section 3(b), the Company shall not be obligated to
provide the benefits to the extent provided by such third party.

     6. Legal Fees and Expenses.  The Company shall promptly reimburse the
Employee for the reasonable legal fees and expenses incurred by the Employee in
connection with enforcing any right of the Employee pursuant to and afforded by
this Agreement; provided, however, that the Company only will reimburse the
Employee for such legal fees and expenses if, in connection with enforcing any
right of the Employee pursuant to and afforded by this Agreement, either (a) a
judgment has been rendered in favor of the Employee by a duly authorized court
of law, (b) a duly authorized court of law determines that the Employee's claim
was not frivolous, or (c) the Company and the Employee have entered into a
settlement agreement providing for the payment to the Employee of any or all
amounts due hereunder.

     7. Confidential Information.  The Employee shall not disclose any secret
or confidential information, knowledge or data relating to the Company or any
of its affiliated companies, and their respective businesses, obtained by the
Employee during his employment by the Company or any of its affiliated
companies and which is not otherwise public knowledge. In no event shall an
asserted violation of the provisions of this Section 7 constitute a basis for
deferring or withholding any amounts or benefits otherwise payable to the
Employee under this Agreement.

     8.  Release from Other Severance Benefits; COBRA.  The Employee hereby
waives and releases the Company from the obligation to pay any severance
benefits to the Employee on account of a termination of employment on or after
a Change of Control, under any termination or severance policy of the Company
other than this Agreement, so long as all payments are made, and benefits
provided, to the Employee pursuant to Sections 3(a) and (b) herein.  To the
extent that the obligation of the Company to provide medical benefits pursuant
to Section 3(b) is fulfilled, 



                                     10

   11

the period in which such medical benefits are provided shall be credited
towards the continued health care coverage required to be offered to the
Employee by COBRA, to the extent allowable under COBRA and the regulations
promulgated thereunder.  In the event that no payment or benefits are required
pursuant to Sections 3(a) and (b), the Employee rescinds any such waiver and
release.

     9. Successors.  (a)  This Agreement is personal to the Employee and,
without the prior written consent of the Company, shall not be assignable by
the Employee otherwise than by will or the laws of descent and distribution.
This Agreement shall inure to the benefit of and be enforceable by the
Employee's legal representatives.

     (b) This Agreement shall inure to the benefit of and be binding upon the
Company and its successors.  The Company shall cause any successor to its
business, in any transaction in which this Agreement would not be assumed by
such successor by operation of law, to assume this Agreement by contract.

     10. Miscellaneous.  (a)  Applicable Law.  This Agreement shall be governed
by and construed in accordance with the laws of the State of North Carolina,
applied without reference to principles of conflict of laws.

     (b) Notices.  All notices and other communications hereunder shall be in
writing and shall be given by hand delivery to the other party or by registered

     (a) Each Participant must irrevocably elect, in accordance with the
procedure set forth in Section 3, the following:

     (1)  The percentages (up to 100% and in 10% increments) of his
          Annual Fees to be received in the form of Stock and in the form of
          cash;
     
     (2)  A percentage (up to 100% and in 10% increments) of his Annual
          Fees to be received in the form of Stock to be deferred under the
          Plan and credited as Stock Equivalents to his Stock Deferral Account
          and a percentage (up to 100% and in 10% increments) of his Annual
          Fees to be received in the form of cash to be deferred under the
          Plan and credited to his Cash Deferral Account; and
     
     (3)  The date on which such Participant's Stock Deferral Account

     In the event the Annual Fees of a Participant is increased during any Plan
Year, his elections in effect shall apply to the amount of such increase.

     (b) Notwithstanding the Participant's elections made in accordance with
paragraph (a) of this Section, prior to the December 15 preceding a Plan Year,
the Board of Directors may, in


                                       4

   5


its sole discretion, determine the proportion of each Non-Employee Director's
Annual Fees which must be paid in Stock for the next following Plan Year.  If
it does so, the Participant's election under Section 5(a)(1) above with respect
to such Plan Year shall apply to any excess amount of the Annual Fees remaining
after payment is made in accordance with the Board of Directors' determination,
and the Participant's elections under Section 5(a)(2) and (3) above shall
remain in effect and apply to the amount of Annual Fees payable in cash and
Stock after application of the previous sentence.

     (a) Crediting of Annual Fees.  The percentage of each Participant's Annual
Fees which he elects to receive in the form of Stock and defer with respect to
a Plan Year in accordance with Section 5 shall be credited to the Participant's
Stock Deferral Account on each Fee Payment Date during the Plan Year, and shall
be converted into that number of Stock Equivalents (rounded down to the nearest
whole share) equal to the amount so credited divided by the Director Purchase
Price.

     (b) Crediting of Dividend Equivalents.  In the event a dividend is paid in
respect of the Stock, an amount equal to such dividend multiplied by the number
of Stock Equivalents credited to a Participant's Stock Deferral Account as of
the record date for such dividend shall be credited to the Participant's Cash
Deferral Account, effective as of the date such dividend is actually paid on
the Stock.

     (c) Adjustments to Deferral Accounts.  The number of Stock Equivalents
credited to each Participant's Stock Deferral Account shall be appropriately
and equitably adjusted to reflect the occurrence of any merger, consolidation,
recapitalization, stock split, reverse stock split, stock dividend or other
non-cash distribution affecting the outstanding Stock.  Such adjustment shall
be made by the Committee.

     (d) Effect of Payments.  The number of Stock Equivalents and the amount of
cash, if any, credited to a Participant's Stock Deferral Account shall be
reduced by the number of shares of Stock and the amount of cash actually paid
to such Participant or his Beneficiary under the Plan.

     (e) Vesting.  The interest of a Participant in any amounts payable with
respect to a Stock Deferral Account shall be at all times fully vested and
non-forfeitable.

each Participant's Annual Fees which he elects to receive in the form of cash

during the Plan Year.  Dividend Equivalents will be credited to  a
Participant's Cash Deferral Account in accordance with Section 6(b).

     (b) Crediting of Interest.  Interest shall be credited on and posted to
each Cash Deferral Account as of the last day of each calendar month beginning
the first calendar month following the effective date of the first deferral and
ending the last calendar month immediately preceding the date on which such
amounts are distributed to the Participant, at an annual rate as determined by
the Committee.

     (c) Effect of Payments.  The amount of cash credited to a Participant's
Cash Deferral Account shall be reduced by the amount of cash paid to such
Participant or his Beneficiary under the Plan.

     (d) Vesting.  The interest of a Participant in any amounts payable with
respect to a Cash Deferral Account shall be at all times fully vested and
non-forfeitable.

     SECTION 8.  PAYMENTS.

     (a) General.  At each time payment of all or a portion of a Participant's
Stock Deferral Account and/or Cash Deferral Account is due pursuant to an
election made in accordance with Section 5 (or pursuant to the death of a
Participant in accordance with Section 8(d)), the Company shall pay Stock and
cash directly to such Participant or his Beneficiary in an amount equal to the
portion of his Stock Deferral Account and/or Cash Deferral Account which is so
payable.  Payable amounts expressed in the form of Stock Equivalents shall be
paid in Stock, and payable amounts expressed in the form of cash shall be paid
in cash.  The Company shall make such payment directly to the Participant from
its general assets and authorized but unissued Stock; provided, however, that
in the event no authorized but unissued Stock is available, payable amounts
from a Participant's Stock Deferral Account expressed in the form of Stock
Equivalents may be deferred for up to six months at the discretion of the
Committee pending the availability of such Stock, and if payment has not been
made at the end of such six-month period, payment shall be promptly made by the
Company in the form of cash, in an amount equal to the Fair Market Value of the
Stock represented by such Stock Equivalents as of the date of payment.

     (b) Date of Commencement.  The payment of a Participant's Stock Deferral
Account and Cash Deferral Account shall commence on the date selected by the
Participant in the irrevocable election described in Section 5; provided,
however, that in no event shall such payment commence later than the date which
is two years following the date on which the Participant ceases to be a
Non-Employee Director for any reason.

     (c) Form of Payment.  A Participant may elect to receive the payment of
his Stock Deferral Account and Cash Deferral Account in the form of (i) a
single lump sum, or (ii) substantially equal annual installments for a period
of up to five years.

     (d) Payment Upon Death.  If a Participant dies before payment of his Stock
Deferral Account and Cash Deferral Account is completed, the balance remaining
in such accounts shall be paid to the Participant's Beneficiary in one lump sum
as soon as practicable following the Participant's death.


                                      6

     (e) Dividends.  Stock Equivalents credited to a Participant's Stock
Deferral Account shall continue to be credited with dividends as described in
Section 6(b) notwithstanding that such Participant has ceased to be a
Non-Employee Director.

     (f) Interest.  Cash credited to a Participant's Cash Deferral Account
shall continue to be credited with interest as described in Section 7(b)
notwithstanding that such Participant has ceased to be a Non-Employee Director.

     (g) Financial Hardship.  Notwithstanding anything herein to the contrary,
a Participant may request and receive a hardship distribution, provided the
Participant is able to demonstrate, to the satisfaction of the Committee, that
he has suffered a Financial Hardship.  A hardship distribution request must be
made on the form provided by the Committee and is subject to the discretion of
the Committee.  The amount distributed cannot exceed the lesser of (a) the
aggregate of the Participant's Cash Deferral Account and Stock Deferral
Account, or (b) the amount necessary to satisfy the Participant's Financial
Hardship.  No distribution may be made prior to the time the Committee approves
the distribution.

     SECTION 9.  DESIGNATION OF BENEFICIARIES.  A Participant may designate one
or more Beneficiaries to receive the amounts payable from the Participant's
Stock Deferral Account and Cash Deferral Account under the Plan in the event of
such Participant's death.  Such designations shall be made on forms provided by
the Committee.  A Participant may from time to time change his designated
Beneficiaries, without the consent of such Beneficiaries, by filing a new
designation in writing with the Committee.  The Company and Committee may rely
conclusively upon the Beneficiary designation last filed in accordance with the
terms of the Plan.

     SECTION 10.  AMENDMENTS TO THE PLAN; TERMINATION OF THE PLAN.  The Board
of Directors of the Company may amend, alter, suspend, discontinue or terminate
the Plan without the consent of any Participant; provided, however, that no
such amendment, alteration, suspension, discontinuation, or termination of the
Plan shall materially and adversely affect the rights of such Participant with
respect to payment of amounts previously credited to such Participant's Stock
Deferral Account and Cash Deferral Account.  The Plan has no fixed termination
date.

     SECTION 11.  GENERAL PROVISIONS.

     (a) Limits on Transfer of Rights; Beneficiaries.  No right or interest of
a Participant under the Plan shall be subject in any manner to anticipation,
alienation, sale, transfer, assignment, pledge, encumbrance, attachment or
garnishment by creditors of the Participant or his Beneficiary, or shall be
transferable by a Participant otherwise than by will or the laws of descent and
distribution; provided, however, that a Participant may designate a Beneficiary
in accordance with Section 9 to receive any payment under the Plan in the event
of death of the Participant.  A Beneficiary, guardian, legal representative or
other person claiming any rights under the Plan from or through any Participant
shall be subject to all terms and conditions of the Plan applicable to such
Participant.


                                      7

     (b) Status of the Plan.  The Plan is intended to be "unfunded" for Federal
income tax purposes.  The Plan shall not cover any employee of the Company and
is not intended to be subject to ERISA.  With respect to any payment not yet
made to a Participant under the Plan, nothing contained in the Plan shall give
a Participant any rights that are greater than those of a general creditor of
the Company.

     (c) No Rights of a Shareholder.  No Participant shall have any of the
rights or privileges of a shareholder of the Company as a result of the making
of an election under Section 5 of the Plan, or as a result of the establishing
of or crediting of any amounts to a Stock Deferral Account under the Plan,
until Stock is actually distributed to the Participant pursuant to Section 8 of
the Plan.

     (d) No Right to Continued Election as a Director.  Nothing contained in
the Plan shall confer, and no establishment of or crediting of any amounts to a
Stock Deferral Account or Cash Deferral Account shall be construed as
conferring, upon any Participant, any right to continue as a member of the
Board of Directors, or to interfere in any way with the right of the Company to
increase or decrease the amount of the Annual Fees, or any other compensation
payable to Non-Employee Directors.

     (e) Plan Expenses.  All expenses and costs incurred in connection with the
operation of the Plan shall be borne by the Company.

     (f) Governing Law.  The validity, construction and effect of the Plan and
any rules and regulations relating to the Plan shall be determined in
accordance with the laws of North Carolina, without giving effect to principles
of conflicts of laws.

     (g) Interpretation.  Whenever necessary or appropriate in the Plan, where
the context admits, the singular term and the related pronouns shall include
the plural and the masculine gender shall include the feminine gender.

                       SUPPLEMENTAL TAX SHARING AGREEMENT


         This SUPPLEMENTAL TAX SHARING AGREEMENT (this "Agreement"), dated as
of September 13, 1996, is made and entered into by and between LOCKHEED MARTIN
CORPORATION, a Maryland corporation ("Lockheed Martin"), and MARTIN MARIETTA
MATERIALS, INC., a North Carolina corporation ("Materials").

                                    RECITALS

         1.      Materials is a New York Stock Exchange listed corporation.
Lockheed Martin owns, directly or indirectly through its wholly owned
subsidiary, Martin Marietta Investments, Inc., 37,350,000 shares (approximately
81% of the outstanding shares) of Materials Common Stock (as defined in Section
1.1).

         2.      Lockheed Martin has determined to distribute all of the shares
it owns in Materials to Lockheed Martin stockholders by means of a transaction
(the "Transaction") intended to qualify as a Tax-Free Distribution (as defined
in Section 1.1).

         3.      Due to compelling strategic business considerations, Lockheed
Martin's and Materials' Boards of Directors have determined that it is in the
best interests of the corporations and their stockholders and shareholders to
effect the Transaction.

         4.      The Board of Directors of Materials has determined that
Materials will realize significant independent benefits as a result of the
Transaction, which benefits will include, among other things:  (a) facilitating
the future issuance by Materials of its stock to finance strategic acquisitions
in pursuit of its growth strategy; (b) permitting Materials to implement more
effective management stock incentive programs and employee stock compensation
programs; (c) permitting Materials to have direct control over its
administrative costs; and (d) allowing Materials' credit rating to be evaluated
independently of Lockheed Martin's credit rating.

         4.      Lockheed Martin and Materials desire to provide for the
allocation of the tax liabilities that would result in the event of a Failure
(as defined in Section 1.1).


         NOW, THEREFORE, in consideration of the premises and the covenants and
agreements contained herein and for other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, each of Lockheed
Martin and Materials, intending to be legally bound, hereby agrees as follows:

                                   ARTICLE I.
                          DEFINITIONS AND CONSTRUCTION

         Section 1.1      Certain Definitions.  As used in this Agreement, the
following terms shall have the meanings specified below:

         "Code" shall mean the Internal Revenue Code of 1986, as amended, or
any successor thereto, as in effect for the taxable period in question.

         "Distribution Tax" shall mean any federal or state tax imposed on a
Person as a result of a Failure, together with any related interest, penalties
or additions to tax.

         "Failure" shall mean the failure of the Transaction for any reason
whatsoever to constitute a  Tax-Free Distribution under Section 355 of the
Code.

         "Fault" shall mean, with respect to each party, and except as
otherwise provided by Section 2.3 of the Tax Assurance Agreement,
responsibility for a Failure where (a) such party engaged in the conduct
described in, or otherwise breached, any of the following sections  of the Tax
Assurance Agreement:  (i) in the case of Materials, Section 2.1, 2.2, 2.4 or
2.5 of the Tax Assurance Agreement or (ii) in the case of Lockheed Martin,
Section 2.5 of the Tax Assurance Agreement and (b) but for such conduct or
breach the Transaction would have been a Tax-Free Distribution; provided,
however, that any misrepresentation by either party made in connection with the
King & Spalding Opinion shall not constitute Fault.  For purposes of clause (b)
of the preceding sentence, in making the determination of whether conduct that
is the subject of this Agreement is the "but for" cause of the Failure, the
only conduct or action that could constitute the "but for" cause of the Failure
is (y) if the government has determined a deficiency and issued a statutory
notice of deficiency, any conduct or action identified in either the statutory
notice of deficiency or the answer to Lockheed Martin's Tax Court petition, or
in the answer to a suit for refund if the issue arises in that posture, as
forming the basis for the government's position that there has been a Failure
and, if a court of competent jurisdiction makes a final determination which is
not subject to appeal that there has been a Failure, any conduct or action
identified in the written decision of that court as a cause of the Failure and
(z) in all other instances, any conduct or action so identified by the
government in writing in connection with its examination of the Lockheed Martin
tax return or any resulting administrative appeal (collectively, the
"Identified Conduct").  For purposes of this Agreement, (a) no conduct or
action other than Identified Conduct may be deemed to have caused the Failure,
(b) the fact that Identified Conduct could constitute the "but for" cause of
the Failure for purposes of this Agreement is not dispositive as to whether any
particular Identified Conduct is in fact the "but for" cause of the Failure and
such determination will be resolved between the parties by agreement or through
litigation, and (c) the Transaction otherwise shall be deemed to have been a
Tax-Free Distribution.





                                     - 2 -

         "King & Spalding Opinion" shall mean the opinions of King & Spalding
which will be delivered in connection with the closing of the Transaction
stating that the Transaction will qualify as a Tax-Free Distribution.

         "Materials Common Stock" shall mean the shares of common stock of
Materials, par value $.01 per share.

         "Opinion of Counsel" shall mean a written opinion of counsel, other
than the King & Spalding Opinion, delivered to Materials relating to the
taxability of the Transaction, which opinion is of a strength and character
appropriate to the issues at stake and which opinion and counsel are reasonably
satisfactory to Lockheed Martin.  For this purpose, the parties agree that
Sutherland, Asbill & Brennan will be deemed satisfactory counsel.  Such Opinion
of Counsel shall be (a) obtained from approved counsel that (i) is engaged by
Materials for the purpose of providing such Opinion of Counsel prior to
Materials' taking substantial steps toward consummating the action that is to
be the subject of the Opinion of Counsel and (ii) is, from the time of its
engagement, actively involved by Materials in Materials' consideration, review
or evaluation of the proposed action or conduct, (b) delivered, together with
copies of supporting documentation relied upon in such Opinion of Counsel, to
Lockheed Martin in sufficient time prior to Materials' consummation of the
action that is the subject of such Opinion of Counsel to allow Lockheed Martin
a reasonable opportunity to review the Opinion of Counsel prior to Materials'
consummation of the action that is the subject of the Opinion of Counsel, and
(c) brought current, with no changes except as expressly agreed by Lockheed
Martin in writing as of the date that Materials consummates the action.  In
addition, such Opinion of Counsel shall expressly provide that Lockheed Martin
is entitled to rely thereon.  Such Opinion of Counsel must state that the
proposed action or conduct, or in the case of a request under Section 2.5(a) of
the Tax Assurance Agreement, the failure to satisfy such request, will neither
cause the Transaction to fail to qualify under Section 355 of the Code nor
cause the distribution to be a disqualified distribution under Section 355(d)
of the Code, without any qualification other than those in the King & Spalding
Opinion or those which are otherwise acceptable to the parties.  Such Opinion
of Counsel (a) may assume the accuracy of the facts and assumptions relied upon
in the King & Spalding Opinion, but only as of the date of the King & Spalding
Opinion, (b) may rely upon written representations, appropriate to the issues
at stake, of parties to the action or conduct which representations have been
subject to due diligence by the approved counsel which due diligence shall be
described in the Opinion of Counsel in reasonable detail, and (c) may assume
that the Transaction would qualify as a Tax-Free Distribution except that such
assumption shall not extend to (i) the action or conduct which is the subject
of the Opinion of Counsel and (ii) other action or conduct of Materials that is
described in Section 2.1, 2.2, 2.4 or 2.5 of the Tax Assurance Agreement and
for which an Opinion of Counsel has not been obtained.  Such Opinion of Counsel
shall be deemed satisfactory to Lockheed Martin unless written notice that it
is unsatisfactory with specifications as to the reasons is given to Materials
as soon as practicable, but no later than 30 days after delivery to Lockheed
Martin pursuant to the notice provisions of Section 3.4 of both such Opinion of
Counsel and the supporting documentation identified in such Opinion of Counsel
as being relied upon.





                                     - 3 -

         "Person" shall mean an individual, a general partnership, a limited
partnership, a limited liability company, an association, a joint venture, a
corporation, a business, a trust, any entity organized under applicable law, an
unincorporated organization or any governmental authority.

         "Tax Assurance Agreement" shall mean the Tax Assurance Agreement, by
and between Lockheed Martin and Materials, entered into in connection with the
Transaction.

         "Tax-Free Distribution" shall mean a distribution qualifying under
Section 355 of the Code that is free from federal income taxes except for taxes
resulting from the recognition of gain or income under the consolidated return
regulations (i.e., taking into account gain from intercompany transactions or
income attributable to excess loss accounts) and gain recognized on the receipt
of cash paid in lieu of fractional shares.  Thus, for example, a distribution
for which gain is recognized as the result of a disqualified distribution
within the meaning of Section 355(d) of the Code is not a Tax-Free
Distribution.

         Section 1.2      Interpretation and Construction of this Agreement.
The definitions in Section 1.1 shall apply equally to both the singular and
plural forms of the terms defined.  Whenever the context may require, any
pronoun shall include the corresponding masculine, feminine or neuter form.
The words "include," "includes" and "including" shall be deemed to be followed
by the phrase "without limitation."  The headings contained in this Agreement
are inserted for convenience only and shall not constitute a part hereof.  All
references herein to Articles and Sections (other than references to Sections
of the Code) shall be deemed to be references to Articles and Sections of this
Agreement unless the context shall otherwise require.  Unless the context shall
otherwise require or provide, any reference to any agreement or other
instrument or statute or regulation is to such agreement, instrument, statute
or regulation as amended and supplemented from time to time (and, in the case
of a statute or regulation, to any successor provision), provided, however,
that no covenant herein shall be deemed to have been breached because of a
change in law or regulation which is enacted or issued subsequent to the
completion of the action or conduct which is the subject of the covenant.  This
Agreement shall be construed in accordance with its fair meaning and shall not
be construed strictly against the drafter.


                                  ARTICLE II.
                                INDEMNIFICATION

         Section 2.1      Indemnification for a Failure for Any Reason Other
Than Fault.  Lockheed Martin and Materials agree that any liability of Lockheed
Martin or Materials for Distribution Taxes to any Person resulting from a
Failure, other than liability arising under Section 2.2 or 2.3, shall be
allocated 81 percent to Lockheed Martin and 19 percent to Materials, provided,
however, that the aggregate liability of Materials under this Section 2.1
(including the sum of the costs, if any, incurred and borne by Materials
pursuant to Section 2.5(a) of the Tax Assurance Agreement), whether such
liability is the result of one or a number of disputes, shall in no event





                                     - 4 -
   5

exceed $25 million.  Lockheed Martin agrees to indemnify and hold harmless
Materials for any liability for Distribution Taxes resulting from a Failure,
other than liability arising under Section 2.2 or 2.3, imposed upon Materials
in excess of the liability allocated to Materials under this Section 2.1.

         Section 2.2      Indemnification for a Failure Because of Fault.
Lockheed Martin and Materials each agrees to indemnify and hold harmless the
other for any liability for Distribution Taxes to any Person resulting from a
Failure as a result of the Fault of the indemnifying party.

         Section 2.3      Indemnification for Liability Arising From a Hostile
Takeover.  Excluding any acquisition of Materials with respect to which it
obtains an Opinion of Counsel, if either Lockheed Martin or Materials is
acquired in a manner that causes a Failure, and the Failure did not result from
the Fault of either party, the liability of Lockheed Martin and Materials for
Distribution Taxes to any Person resulting from such Failure shall be allocated
solely to the party so acquired.  To the extent that this Section 2.3 is
applicable, it shall apply with respect to any liability arising from the
Failure, and Sections 2.1 and 2.2 shall not apply to such extent.

         Section 2.4      Exclusive Remedy.  The remedies provided in this
Article II constitute the sole and exclusive remedies for recoveries by each of
the parties against the other arising out of, based upon, or in connection with
a Failure.  Neither Lockheed Martin nor Materials shall assert any right or
make any claim to recover or seek relief for a Failure on any basis other than
as provided in this Agreement, including, but not limited to, rights or claims
in contract or tort (including fraud and fraudulent misrepresentation), at law
or in equity, under common law or statute, or otherwise.  Each of Lockheed
Martin and Materials waives any and all such rights or claims except for rights
or claims arising pursuant to the express terms of this Agreement and the Tax
Assurance Agreement.

         Section 2.5      Notice of Investigation.  If either Lockheed Martin
or Materials receives any written notice that a taxing authority is considering
treating the Transaction as not qualifying under Section 355 of the Code or as
constituting a disqualified distribution within the meaning of Section 355(d)
of the Code, the party receiving such notice shall promptly give written notice
thereof to the other party.  Each party agrees that from and after such time as
it obtains knowledge that any representative of a taxing authority has formally
begun to investigate or inquire as to the tax-free status of the Transaction,
it will notify the other, consult with the other from time to time as to the
conduct of such investigation or inquiry, and provide the other with copies of
all correspondence between it or its representatives and such taxing authority
pertaining to such investigation or inquiry.  Each party agrees that, from such
time as the taxing authorities have proposed an adjustment based upon the
Transaction not constituting a Tax-Free Distribution, it shall, to the extent
possible, arrange for a representative of the other to be present at all
meetings with such taxing authority or any representative thereof pertaining to
such investigation or inquiry, permit the other to consult with respect to such
disputes, and, if the other party may be liable under Section 2.2 or 2.3,
permit the other to participate in the resolution of any such disputes.

         Section 2.6      Tax Benefit.  In determining any liability for
indemnification under this Article II, the parties shall take into account the
extent of any tax benefit realized by the indemnitee with respect to the
obligation for which there is an indemnification obligation under this
Agreement.


                                  ARTICLE III.
                          PROCEDURAL AND OTHER MATTERS

         Section 3.1      Forms 1099.  Lockheed Martin shall file on behalf of
and at the expense of Materials all Forms 1099 due with respect to the receipt
by Materials' shareholders of any cash paid in lieu of fractional shares in the
Transaction.

         Section 3.2      Form of Payment.  Whenever payment is required under
this Agreement, payment shall be made in cash by wire transfer of immediately
available funds.

         Section 3.3      Character of Payments; Gross-Up.  All payments made
by any party pursuant to this Agreement or Section 2.5(a) of the Tax Assurance
Agreement shall be treated as the discharge of liabilities incurred by such
party in connection with the Transaction.  If, notwithstanding such treatment
by the parties, payment by any party is finally determined to be taxable to the
other party by any taxing authority, there shall be a gross-up with respect to
such payment to such other party to the extent necessary to fully indemnify the
indemnitee on an after-tax basis.  The amount of such gross-up shall be
determined consistent with all of the principles contained in this Agreement
and the Tax Assurance Agreement.  Thus, for example, the gross-up payment, as
well as the amount of the indemnified liability, shall take into account the
extent of the tax benefits, if any, realized by the indemnitee with respect to
the obligation for which there is an indemnification obligation under this
Agreement or the Tax Assurance Agreement, and if the indemnification arises
under Section 2.1 of this Agreement (or Section 2.5(a) of the Tax Assurance
Agreement), all costs and the amount of the gross-up shall be apportioned 81%
to Lockheed Martin and 19% to Materials, subject to any applicable limitations
on the aggregate liability of Materials.  Any such gross-up with respect to the
liabilities that may arise under Section 2.1 or the Tax Assurance Agreement
shall be treated as a liability of Materials for the purpose of determining its
aggregate liability under Section 2.1 such that, notwithstanding such gross-up,
Materials' aggregate liability shall be limited to $25 million.

         Section 3.4      Notices.  Any notice, demand, claim or other
communication under this Agreement shall be in writing and shall be deemed to
have been given on the earliest of the following:

            (a)  upon the delivery thereof if delivered personally;

            (b)  on the date on which delivery thereof is guaranteed
                 by the carrier if delivered by a national courier
                 guaranteeing delivery within a fixed number of days
                 of sending; or




                                     - 6 -

            (c)  on the date on which facsimile transmission thereof is
                 confirmed "OK" by the receiving machine if transmitted by
                 facsimile machine and confirmed by delivery by one of the
                 prior methods;

but, in each case, only if addressed to the parties in the following manner at
the following addresses or facsimile numbers ("Fax") (or at such other address
or other facsimile number as a party may specify by written notice to the
other):

other agreement or understanding between the parties dealing with a different
subject matter that was executed contemporaneously with this Agreement.  Except
with respect to any subsequent written modifications of this Agreement, this
Agreement, the Tax Sharing Agreement and the Tax Assurance Agreement supersede
any prior agreements or understandings and abrogate any inconsistent provisions

any power or right under this Agreement will operate as a waiver thereof, nor
will any single or partial exercise of any right or power, or any abandonment
or discontinuance of steps to enforce such right or power, preclude any other
or further exercise thereof or the exercise of any other right or power.

         Section 4.4      Survival.  The covenants and agreements contained

                           TAX ASSURANCE AGREEMENT


         This TAX ASSURANCE AGREEMENT (this "Agreement"), dated as of September
13, 1996, is made and entered into by and between LOCKHEED MARTIN CORPORATION,
a Maryland corporation ("Lockheed Martin"), and MARTIN MARIETTA MATERIALS,
INC., a North Carolina corporation ("Materials").


                                  RECITALS

         1.      Materials is a New York Stock Exchange listed corporation.
Lockheed Martin owns, directly or indirectly through its wholly owned
subsidiary, Martin Marietta Investments, Inc., 37,350,000 shares (approximately
81% of the outstanding shares) of Materials Common Stock.

         2.      Lockheed Martin has determined to distribute all of the shares
it owns in Materials to Lockheed Martin stockholders by means of a transaction
(the "Transaction") intended to qualify as a Tax-Free Distribution.

         3.      Due to compelling strategic business considerations, Lockheed
Martin's and Materials' Boards of Directors have determined that it is in the
best interests of the corporations and their stockholders and shareholders to
effect the Transaction.

         4.      The Board of Directors of Materials has determined that
Materials will realize significant independent benefits as a result of the
Transaction, which benefits will include, among other things: (a) facilitating
the future issuance by Materials of its stock to finance strategic acquisitions
in pursuit of its growth strategy; (b) permitting Materials to implement more
effective management stock incentive programs and employee stock compensation
programs; (c) permitting Materials to have direct control over its
administrative costs; and (d) allowing Materials' credit rating to be evaluated
independently of Lockheed Martin's credit rating.

         5.      It is fundamental to achieving the strategic benefits of the
Transaction that it qualify as a Tax-Free Distribution.

         6.      Lockheed Martin and Materials have mutually agreed to enter
into this Agreement in order to give assurances to each other that the
Transaction will constitute a Tax-Free Distribution.

         NOW, THEREFORE, in consideration of the premises and the covenants and
agreements contained herein and for other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, each of Lockheed 
Martin and Materials, intending to be legally bound, hereby agrees as follows:

                                   COVENANTS

Other Materials Stock (whether from Materials or from one or more shareholders
of Materials), but excluding any conduct undertaken to permit, facilitate or

                 (e)      any redemptions, repurchases or other acquisitions of

acquisitions are made (w) pursuant to a negotiated or private transaction with
respect to which discussions or negotiations commence no earlier than the end

redemptions, repurchases or other acquisitions in a single transaction or a
series of related transactions will not exceed 250,000 shares of Materials
Common Stock or (x) in the open market, (ii) Materials does not have any reason
to believe that such redemptions, repurchases or other acquisitions are made

         Section 2.3.     Exception to Fault.  Notwithstanding anything to the
contrary in this Agreement:

                 (a)      if Materials obtains an Opinion of Counsel with
respect to any conduct, action or inaction that might otherwise constitute
Fault, excluding conduct, action or inaction under Section 2.5(b), Materials
shall not be at Fault with respect to any Failure resulting from the conduct or
action that is the subject of the Opinion of Counsel and Materials' only
indemnification obligation shall be determined pursuant to Sections 2.1 and 2.3
of the Supplemental Tax Sharing Agreement; and

                 (b)      any conduct or action either party is required to
take (or refrain from taking) as a matter of law shall not form a basis for
Fault.

         Section 2.4      Additional Covenant by Materials.  With respect to
any written representation Materials delivers to the approved counsel in
connection with any Opinion of Counsel, and to the extent such representation
pertains to future actions or conduct by Materials (or any Affiliate, agent or
representative of Materials) and is expressly referred to in such Opinion of
Counsel, neither Materials nor any of its Affiliates nor any of their
respective officers, directors, employees, agents or representatives will take
any action (unless Materials receives an Opinion of Counsel with respect to
such action based on principles substantially identical to those set forth in
this Agreement) during the two-year period following the making of such
representation (the "Effective Period") that would have caused such
representation to be untrue if Materials or any such other Person had planned
or intended to take such action at the time Materials made the representation. 
Materials' covenants and agreements contained in this Section 2.4 shall survive
until the later to occur of (a) the expiration of the Restricted Period and (b)
the expiration of all outstanding Effective Periods.

         Section 2.5      Mutual Covenants by Lockheed Martin and Materials.

                 (a)      In addition to the other covenants and agreements set
forth in this Agreement, each party and its Affiliates, officers, directors,
employees, agents and representatives will take, or refrain from taking, as the
case may be, such actions as the other party may reasonably request as
necessary to ensure that the Transaction is a Tax-Free Distribution, including
such actions as may be necessary to obtain or to prevent the withdrawal of the
King & Spalding Opinion.

                          (i)     For purposes of this Section 2.5(a), in
determining what constitutes a reasonable request, all facts and circumstances
shall be considered including, without limitation, (y) the nature of risk to
the status of the Transaction as a Tax-Free Distribution if the request were
not satisfied and (z) the burden, if any, associated with satisfying the
request; in no event shall a request to Materials to take or refrain from
taking certain actions constitute a reasonable request if Materials obtains an
Opinion of Counsel stating that failing to comply with the request 



                                    - 6 -

   7

will neither cause the Transaction to fail to qualify under Section 355 of the
Code nor cause the distribution to be a disqualified distribution under Section
355(d) of the Code.

                          (ii)    Without limiting the generality of the
foregoing, each party shall cooperate with the other if either party determines
to obtain any additional Opinion of Counsel pertaining to whether any actual or
proposed change in facts and circumstances affects the tax status of the
Transaction.

                          (iii)   The incremental costs arising from any action
taken by a party pursuant to one or more requests by the other party under this
Section 2.5(a) shall be borne as follows:  regardless of whether such costs
arise from one or more requests, the first $1 million of such costs (determined
on a cumulative basis) shall be borne entirely by the party of whom such
requests are made and any excess of such costs shall be borne 81% by Lockheed
Martin and 19% by Materials; provided, however, that the incremental costs
incurred and to be borne by Materials pursuant to this Section 2.5(a) shall in
no event exceed $25 million and shall be treated as a liability for purposes of
determining the aggregate liability of Materials under Section 2.1 of the
Supplemental Tax Sharing Agreement.  In determining the incremental costs for
purposes of this Section 2.5(a)(iii), only the actual out-of-pocket costs,
reduced by the incremental actual cash receipts and taking into account all
income tax benefits or costs associated with such costs or receipts, shall be
taken into account.

                          (iv)    To be effective, any request pursuant to this
Section 2.5(a) must be made in accordance with notice provisions of Section 3.2
and must conspicuously bear the following language:  "THIS IS A REQUEST
PURSUANT TO SECTION 2.5(a) OF THE TAX ASSURANCE AGREEMENT RELATING TO ENSURING
THAT THE DISTRIBUTION OF MARTIN MARIETTA MATERIALS IS A TAX-FREE DISTRIBUTION."

announcement or writing disseminated to the public, if such tax return, report,
document, announcement or writing discusses or describes the tax aspects or

understanding of the parties in respect of the subject matter contained herein
and in those documents.  This provision shall not abrogate any other agreement
or understanding between the parties dealing with a different subject matter
that was executed contemporaneously with this Agreement.  Except with respect to
any subsequent written modifications of this Agreement, this Agreement, the Tax
Sharing Agreement and the Supplemental Tax Sharing Agreement supersede any prior
agreements or understandings and abrogate any inconsistent provisions of any
contemporaneous agreements or understandings between the parties with respect to
the subject matter contained in this Agreement, the Tax Sharing Agreement and
the Supplemental Tax Sharing Agreement.

         Section 3.4      Waiver, Amendment, etc.  This Agreement may not be
amended or supplemented, and no waivers of or consents to departures from the
provisions hereof shall be effective, unless set forth in a writing signed by,
and delivered to, each party.  No failure or delay of any party in exercising
any power or right under this Agreement will operate as a waiver thereof, nor
will any single or partial exercise of any right or power, or any abandonment or
discontinuance of steps to enforce such right or power, preclude any other or
further exercise thereof or the exercise of any other right or power.

         Section 3.5      Governing Law.  THIS AGREEMENT SHALL BE INTERPRETED,
AND THE RIGHTS, OBLIGATIONS AND LIABILITIES OF THE PARTIES HERETO DETERMINED,
IN ACCORDANCE WITH THE INTERNAL LAWS (AS OPPOSED TO CONFLICTS OF LAW

         Section 3.6.     Consent to Jurisdiction.  LOCKHEED MARTIN AGREES THAT

MATERIALS AGREES THAT IT WILL BRING ANY ACTION OR PROCEEDING FOR THE
ENFORCEMENT OF ANY RIGHT, REMEDY, OBLIGATION OR LIABILITY ARISING UNDER OR IN

OR PROCEEDING AGAINST THE OTHER EXCEPT IN ACCORDANCE WITH THE PRECEDING
SENTENCES.  EACH PARTY CONSENTS THAT ALL SERVICE OF PROCESS MAY BE MADE BY
REGISTERED OR CERTIFIED MAIL DIRECTED TO THE PARTY AT THE ADDRESS STATED IN
SECTION 3.2.

         Section 3.7      Severability.  The invalidity or unenforceability of
any provision hereof in any jurisdiction will not affect the validity or
enforceability of the remainder hereof in that jurisdiction or the validity or
enforceability of this Agreement, including that provision, in any other
jurisdiction.  To the extent permitted by applicable law, each party waives any
provision of applicable law that renders any provision hereof prohibited or
unenforceable in any respect.  If any 



                                    - 10 -

   11


provision of this Agreement is held to be unenforceable for any reason, it shall
be adjusted rather than voided, if possible, in order to achieve the intent of
the parties to the extent possible.

         Section 3.8      Counterparts.  This Agreement may be executed in one
or more counterparts, each of which shall be deemed to be an original, but all
of which together shall constitute one and the same instrument.

         Section 3.9      Binding Agreement.  This Agreement shall be binding
upon and inure only to the benefit of the parties hereto and their respective
successors and permitted assigns (by merger, acquisition of assets, or
otherwise) to the same extent as if the successor or assign had been an
original party to this Agreement.

         Section 3.10     No Third Party Beneficiaries. This Agreement is not
intended to benefit any Person other than the parties hereto and their
respective successors and permitted assigns, and no such Person shall be a
third party beneficiary hereof.

         Section 3.11     Assignment.  Neither Lockheed Martin nor Materials
shall assign this Agreement or any rights, interests or obligations hereunder,
or delegate performance of any of its obligations hereunder, without the prior
written consent of the other party.

         Section 3.12     Costs and Expenses.  All costs and expenses incurred
by Materials or Lockheed Martin relating to any Opinion of Counsel shall be
paid by the party seeking such Opinion of Counsel, and each party agrees to
indemnify the other against any and all such costs and expenses.

         Section 3.13     Books, Records and Documentation.  Each party shall
keep, maintain and preserve books, records and documentation necessary in or
applicable to the determination of liabilities pursuant to the Supplemental Tax
Sharing Agreement or this Agreement and the establishment of the Transaction as
a Tax-Free Distribution until the expiration of all applicable statutes of
limitations.

         Section 3.14     Termination.  The rights and obligations of the
parties to this Agreement shall terminate, and neither party shall have any
liability under this Agreement, if the Transaction is not consummated.


         IN WITNESS WHEREOF, Lockheed Martin and Materials have caused their
respective duly authorized officers to execute this Agreement as of the day and
year first above written.
