PART II INFORMATION REQUIRED IN THE REGISTRATION STATEMENT Item 3.

(b) The description of the Registrant's Common Stock contained in the Registrant's Registration Statement on Form 8-B filed with the Commission pursuant to Section 12 of the Securities Exchange Act of 1934 (the "Exchange Act") (as amended on Form 8-B/A filed with the Commission on March 9, 1995), and any amendment or report filed for the purpose of updating such description; (c) Martin Marietta Corporation's Current Report on Form 8-K filed with the Commission on February 13, 1995; (d) Martin Marietta Corporation's Current Report on Form 8-K filed with the Commission on February 17, 1995; (e) Lockheed Corporation's Current Report on Form 8-K filed with the Commission on February 21, 1995; and (f) The Registrant's Current Report on Form 8-K filed with the Commission on March 15, 1995. All documents subsequently filed by the Registrant, Martin Marietta Corporation, Lockheed Corporation or the Plan pursuant to Sections 13(a), 13(c), 14 or 15(d) of the Exchange Act prior to filing of a post-effective amendment which indicates that all securities offered have been sold or which removes from registration all securities then remaining unsold, shall be deemed to be incorporated by reference into this Registration Statement and to be a part hereof from the date of the filing of such documents. Item 4. Description of Securities. ------------------------- Not Applicable - 1 - Item 5. Interests of Named Experts and Counsel. -------------------------------------- The Opinion of Counsel as to the legality of the securities being issued (constituting Exhibit 5) has been rendered by counsel who is a full-time employee of the Registrant. Counsel rendering such opinion is not eligible to participate in the Plan. Item 6. Indemnification of Directors and Officers. ----------------------------------------- The Maryland General Corporation Law authorizes Maryland corporations to limit the liability of directors and officers to the corporation or its stockholders for money damages, except (a) to the extent that it is proved that the person actually received an improper benefit or profit in money, property or services, for the amount of the benefit or profit in money, property or services actually received, (b) to the extent that a judgment or other final adjudication adverse to the person is entered in a proceeding based on a finding that the person's action or failure to act was the result of active and deliberate dishonesty and was material to the cause of action adjudicated in the proceeding or (c) in respect of certain other actions not applicable to the Registrant. Under the Maryland General Corporation Law, unless limited by charter, indemnification is mandatory if a director or an officer has been successful on the merits or otherwise in the defense of any proceeding by reason of his or her service as a director unless such indemnification is not otherwise permitted as described in the following sentence. Indemnification is permissive unless it is established that (a) the act or omission of the director was material to the matter giving rise to the proceeding and was committed in bad faith or was the result of active and deliberate dishonesty, (b) the director actually received an improper personal benefit in money, property or services or (c) in the case of any criminal proceeding, the director had reasonable cause to believe his or her act or omission was unlawful. In addition to the foregoing, a court of appropriate jurisdiction may under certain circumstances order indemnification if it determines that the director or officer is fairly and reasonably entitled to indemnification in view of all the relevant circumstances, whether or not the director or officer has met the standards of conduct set forth in the preceding sentence or has been adjudged liable on the basis that a personal benefit was improperly received in a proceeding charging improper personal benefit to the director or officer. If the proceeding was an action by or in the right of the corporation or involved a determination that the director or officer received an improper personal benefit, however, no indemnification may be made if the individual is adjudged liable to the corporation, except to the extent of expenses approved by a court of competent jurisdiction. Article XI of the charter of the Registrant limits the liability of directors and officers to the fullest extent permitted by the Maryland General Corporation Law. Article XI of the charter of the Registrant also authorizes the Registrant to adopt by-laws - 2 - or resolutions to provide for the indemnification of directors and officers. Article VI of the By-laws of the Registrant provides for the indemnification of the Registrant's directors and officers to the fullest extent permitted by the Maryland General Corporation Law. In addition, the Registrant's directors and officers are covered by certain insurance policies maintained by the Registrant. Item 7. Exemption from Registration Claimed. ----------------------------------- Not Applicable Item 8. Exhibits. -------- 4.

Consent of Ernst & Young, LLP (Los Angeles, CA). 23-C. Consent of KPMG Peat Marwick LLP. 23-D. Consent of Arthur Andersen LLP. 23-E. Consent of Stephen M.

Powers of Attorney (included as an exhibit to a Registration Statement on Form S-8 relating to the Lockheed Martin Corporation Directors Deferred Stock Plan filed by the Registrant with the Commission on March 15, 1995 and incorporated herein by reference). The Registrant hereby undertakes that the Registrant will submit or has submitted the Plan and any amendment thereto to the Puerto Rico Department of Treasury in a timely manner and has made or will make all changes required by the Puerto Rico Department of Treasury in order to qualify the Plan. The Plan is intended to be qualified under Puerto Rico tax laws, but not United States tax laws and, accordingly, no determination letter will be requested from U.S. Internal Revenue Service. Item 9. Undertakings. ------------ (a) The undersigned Registrant hereby undertakes: (1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement: (i) To include any prospectus required by section 10(a)(3) of the Securities Act of 1933; - 3 - (ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post- effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement; (iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement; Provided, however, that subparagraphs (1)(i) and (1)(ii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed by the Registrant pursuant to section 13 or section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement. (2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering. (b) The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the Registrant's annual report pursuant to section 13(a) or section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (c) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its - 4 - counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue. - 5 - SIGNATURES Pursuant to the requirements of the Securities Act of 1933, the Registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-8 and has duly caused this registration statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the County of Montgomery, State of Maryland.

                                  INTRODUCTION


          The Performance Sharing Plan for Puerto Rico Employees (the "Plan")
was established, effective April 4, 1993, by the Board of Directors of Martin
Marietta Corporation (the "Corporation") to provide its Puerto Rico employees
with the opportunity to participate in a systematic, substantial, and personal
savings and retirement program which will provide a way to reward employees
based on total Corporation performance.

          This Plan and the Trust created thereby are for the exclusive benefit
of participating employees and their beneficiaries.  They are designed to comply
with the Employee Retirement Income Security Act of 1974, as amended, and to
qualify under Section 165(a) of the Puerto Rico Income Tax Act of 1954, as
amended, as a profit-sharing plan with a qualified cash or deferred arrangement
as defined in Section 165(e) of the ITA. Except as provided in the Plan, in no
manner shall any assets in the Trust revert to the Corporation.

                                 CONTRIBUTIONS



(1)  CONTRIBUTION ELECTIONS

     (a) As required by Article II(2)(d), an Employee must enter into an
agreement in a form acceptable to the Plan Administrator under which he elects
CODA Contributions (see Section (2)), Thrift Contributions (see Section (3)), or
both, in order to become a Participant. Subject to the limitations of Sections
(2) and (3) of this Article, the Participant's Contribution election must
specify the percentages of the Participant's Base Salary to be contributed to
the Trust Fund as CODA Contributions and/or Thrift Contributions. The elected
percentages must be in multiples of 1% of Base Salary. A Participant may elect
Supplemental CODA Contributions or Supplemental Thrift Contributions only if the
Basic CODA Contributions and Basic Thrift Contributions which will be made by
him, or on his behalf, are at the maximum level permitted under Sections
(2)(a)(i) and (3)(a) of this Article.

     (b) A Participant's contribution election shall become effective as 
follows:

           (i) The contribution election of an Employee who has suspended
contributions, either voluntarily or as a result of a hardship withdrawal under
Article IV(2), shall be effective as of the first pay period of the month
following the month that the Plan Administrator receives the contribution
election, provided such receipt occurs on or before the 20th of the month. If
the Plan Administrator receives a contribution election after the 20th of any
month, such election shall be effective as of the first pay period of the second
month following the month that the Plan Administrator receives the contribution
election.

           (ii) The contribution election for any Employee who meets the
 eligibility requirements of Article II (other than a Participant described in
 subparagraph (i) above) shall be effective as of the first pay period of the
 month following the month that the Plan Administrator receives the contribution
 election, provided such receipt occurs on or before the 20th of the month. If
 the Plan Administrator receives a contribution election after the 20th of any
 month, such election shall be effective as of the first pay period of the
 second month following the month that the Plan Administrator receives the
 contribution election.

           (iii) The Plan Administrator shall establish such contribution
election procedures for the initial contributions to this Plan as the Plan
Administrator deems reasonable and appropriate under the circumstances and shall
communicate such procedures to all then Employees who have satisfied the
requirements to elect to make contributions to this Plan.

     (c) Subject to the limitations of Sections (2) and (3) of this Article, a
Participant's

                                       9

 
Contribution election shall remain in effect until (i) the Participant changes
or suspends the election as provided in subsection (d) of this Section, or (ii)
the Participant is required to suspend his election to make contributions as a
result of a withdrawal pursuant to Article IV(l) or IV(2). If a Participant
ceases to be an Employee, his Contribution election will be terminated, and no
further CODA and Thrift Contributions will be made under this Article to the
Plan unless and until he again becomes an Employee and a new agreement becomes
effective. In the event of an adjustment in Base Salary, the dollar amount of
Contributions shall thereafter be automatically adjusted in accordance with the
percentages set forth in the Contribution election which is in effect at the
time the adjustment in Base Salary is made.

     (d) A Participant may suspend or change the level of either category of
CODA or Thrift Contributions effective as of the first pay period of the month
after the Plan Administrator or his delegate receives notice of such
modification of Contribution election provided such receipt occurs on or before
the 20th of the month. If the Plan Administrator receives notice of a
contribution modification after the 20th of any month, such modification shall
be effective as of the first pay period of the second month following the month
that the Plan Administrator receives such notice. The notice shall be in
accordance with requirements established by the Plan Administrator for such
purpose. A Contribution election, as so modified, shall thereafter remain in
effect as provided in subsection (c).

     (e) Any CODA Contributions and Thrift Contributions made pursuant to a
Participant's Contribution election shall be paid into the Trust Fund for
investment according to the investment options selected by the Participant. Such
Contributions and earnings thereon shall not be subject to forfeiture.

(2) CODA CONTRIBUTIONS

     (a) CODA Contributions consist of Basic CODA Contributions and Supplemental
CODA Contributions.  A Participant may elect:

           (i) Basic CODA Contributions at a rate of up to 6% (7% for Employees
with three or more years of service as of the beginning of the Plan Year for
which the Contribution is being made) of his Base Salary for the portion of the
Plan Year during which he makes such Basic CODA Contributions,

           (ii) Supplemental CODA Contributions at a rate of up to 4% (3% for
Employees with three or more years of service as of the beginning of the Plan
Year for which the contribution is being made) of Base Salary, and

           (iii) For any Transferred Employee, any additional Basic and
Supplemental CODA Contributions necessary in order to avoid a reduction in CODA
Contributions for the 1993 Plan Year due to a delay, if any, in enrollment of
such Transferred. Employee

                                      10

Administrator.

     (b) Notwithstanding the foregoing, CODA Contributions shall be subject to
the following further limitations:

           (i) The sum of a Participant's total CODA Contributions to this Plan
and elective deferrals to any other plan maintained by the Employer shall not
exceed $7,000 for that Plan Year; and

           (ii) The CODA Contributions of any Highly Compensated Employee shall
be limited as necessary to ensure that the Plan satisfies one of the two tests
relating to elective contributions contained in ITA Section 165(e)(3)(A).

     The Administrative Committee shall undertake to monitor the level of CODA
Contributions under the Plan in a manner that will enable affected Participants
to have advance notice, whenever practicable, as to what level of CODA
Contributions will be accepted consistent with the limitations set forth above.
Notwithstanding any other provisions of this Article, the Administrative
Committee shall reduce the elected percentage of CODA Contributions (beginning
first with any Supplemental CODA Contributions), if the Administrative Committee
determines in its sole discretion that such reduction is necessary to assure
compliance with the limitations set forth above.

     (c) Once any Participant's CODA Contributions under this Plan and any other
plans maintained by the Employer (or, for Plan Year 1993, General Electric
Company) reach the $7,000 limitation; Contributions for the rest of the Plan
Year that would have been CODA Contributions but for such limitation will be
deemed to be Thrift Contributions. If a Participant notifies the Plan
Administrator in writing not later than the first March 1 following the close of
the Participant's taxable year that, notwithstanding the first sentence of this
paragraph, the sum of all the elective deferrals made by the Participant to all
plans in which he participated in that taxable year exceeded the $7,000
limitation, then the amount identified by the Participant as exceeding the
$7,000 limitation and the allocable portion of the income earned on the excess
deferral during the Plan Year in which the Contribution was made shall be
distributed to the Participant.

     (d) If a Participant's elected percentage of CODA Contributions must be
limited under paragraph (ii) of subsection 2(b) above the required reduction
shall be recharacterized as Basic or Supplemental Thrift Contributions and
retained in the Plan. For the purposes of this subsection 2(d), CODA
Contributions (beginning with Supplemental CODA Contributions) will be reduced
for the Highly Compensated Employees with the highest percentage of CODA
Contributions relative to the Employee's compensation as necessary to bring such
CODA Contributions into compliance with the limitations imposed by the ITA. The
amount of the reduction shall be increased by the amount of any income (or
decreased by the amount of any loss) allocable to the Plan

                                      11

 
Year for which the CODA Contribution was made. In determining whether the
limitations set forth above have been met, the Administrative Committee will use
each Participant's compensation for the portion of the Plan Year during which
such individual was eligible to be a Participant. Any reduction of an election
of CODA Contributions under this subsection shall be made on a reasonable and
nondiscriminatory basis. Nothing contained in this subsection shall be
interpreted to limit the Committee's right to reduce, curtail, or make a
distribution of any form of Contributions under the Plan in order to satisfy the
requirements of Article VI(4).

(3) THRIFT CONTRIBUTIONS

     Thrift Contributions consist of Basic Thrift Contributions and Supplemental
Thrift Contributions.  A Participant may elect to make:

           (a) Basic Thrift Contributions at a rate (applied to his Base Salary
for the portion of the Plan Year during which he makes such Basic Thrift
Contributions) up to the difference between 6% (7% for Employees who have at
least three years of service by the beginning of the Plan Year for which the
Contribution is being made) and the rate of Basic CODA Contributions in effect

           (b) Supplemental Thrift Contributions at a rate (applied to his Base
Salary for the portion of the Plan Year during which he makes such Supplemental
Thrift Contributions) up to the difference between 11% (10% for Employees with

and the rate of Supplemental CODA Contributions in effect for the same pay
period; and

           (c) For any Transferred Employee, any additional Basic and
Supplemental Thrift Contributions necessary in order to avoid a reduction in
Thrift Contributions for the 1993 Plan Year due to a delay, if any, in
enrollment of such Transferred Employee following April 4, 1993, in accordance
with procedures established by the Plan Administrator.

           (d) The Administrative Committee shall undertake to monitor the level
of Thrift Contributions under the Plan in a manner that will enable affected
Participants to have advance notice, whenever practicable, as to what level of
Thrift Contributions will be accepted consistent with the limitations set forth
above.

(4)  ROLLOVER CONTRIBUTIONS

           (a) Subject to the approval of the Administrative Committee, a
Participant or a Limited Participant who receives a distribution from an

of each such Participant. The amount of the Matching Contribution for each
Participant shall be 50% of such Participant's Basic CODA and Basic Thrift
Contributions.

(6)  LIMIT ON TOTAL CORPORATION CONTRIBUTIONS

     The total amount of Matching Contributions and CODA Contributions for a
taxable year shall not be greater than the maximum amount of Contributions
permitted by law as a tax deductible expense to the Employing Companies for such
taxable year under ITA Section 23(p), or under any other applicable provisions
of the ITA.

(7)  PLAN TO PLAN TRANSFER

     Subject to the approval and direction of the Administrative Committee, the
Trustee may accept as part of the Trust Fund, property transferred from a plan

           (a) A Participant may withdraw an amount from the portion of his
Account attributable to CODA Contributions, Thrift Contributions, or Rollover

incurred a Hardship only if he demonstrates to the satisfaction of the
Administrative Committee that the distribution is necessary on account of an
immediate and heavy financial need of the Participant and is necessary to
satisfy the need. The amount withdrawn may not exceed the amount determined by
the Committee to be required to meet the immediate financial need and not

Hardship, the Committee shall act in accordance with uniform and
nondiscriminatory standards and on the basis of such information and evidence as
it shall reasonably require from the Participant. Any withdrawal on account of
hardship shall be paid first from a Participant's Thrift

Contributions, second from Rollover Contributions, third from income earned on
CODA Contributions, fourth from Supplemental CODA Contributions, and fifth from
Basic CODA Contributions.

           (b) A request for a withdrawal will be considered to be on account of
an immediate and heavy financial need if the withdrawal is for

Section 213(d) of the Code) previously incurred by the employee, the employee's
spouse or any dependents of the employee or necessary for these persons to
obtain medical care (as defined in Section 213(d) of the Code) in advance of
medical treatment;

               (ii) costs directly related to the purchase of a principal

from the employee's principal residence or foreclosure on the mortgage on that
residence; or

               (v) other extraordinary and non-recurring events which in the
opinion of the Administrative Committee constitute a hardship creating an
immediate and heavy financial need.

           c) A withdrawal will generally be considered necessary to satisfy an
immediate and heavy financial need if:

               (i) the distribution is not in excess of the amount of the
immediate and heavy financial need (including, to the extent requested by the
Participant, any amounts necessary to pay any income taxes or penalties
reasonably anticipated to result from the distribution);

               (ii) the employee has obtained all distributions other than
hardship distributions, and all nontaxable loans currently available under all
plans maintained by the Employer; and

need cannot be satisfied through reimbursement or compensation by insurance or
otherwise, liquidation of the employee's assets, cessation of CODA and Thrift
Contributions, other distributions or loans from any Employer's plan, or by
borrowing from Commercial sources on reasonable commercial terms.

                                      15

Accounts because of a Hardship must suspend his election to make any CODA
Contributions or any Thrift Contributions to this Plan for a period of six

and/or CODA Contributions by entering into a new agreement in accordance with
the requirements of Section (1) of Article III.

proportion to the value of the investment of such portion of his Account in such
Fund on such Valuation Date.

          with the Plan's normal processing standards and procedures. The
          Valuation Date for the distribution will be the last day of the month
          preceding the month in which the Participant's payment record is

of age 84, as follows:

          (i) The first annual payment will be made as soon as practicable, on
          or after the last day of the month in which the Participant elects to
          have the installment payment begin, but in no event later than the
          time specified in Section 4(a)(ii). All subsequent installments will
          be paid on each succeeding anniversary of the first installment or as
          soon as practicable thereafter. The amount of each annual payment will
          be determined by

          after the payment of the first installment has been made; provided
          that an Employee who elects such an interim withdrawal may not make
          another interim withdrawal for at least 24 months following the
          Employee's prior interim withdrawal.
          (iii)  In the event that at any Valuation Date, the balance in an
          Employee's Account is $1,000 or less, the entire Account balance will
          be distributed to him on the next date for which an installment
          payment is scheduled or an interim withdrawal is elected. Such
          distribution will be in full satisfaction of such Employee's rights
          under this Plan.
          (iv)  In the event the Participant dies prior to a complete
          distribution of his Account, the balance of his Account will be paid
          in a single lump sum payment to his Beneficiary in accordance with (a)
          or (b) above.
          (v) All payments under this paragraph 4(c) shall be valued as of the
          Valuation Date preceding the month in which the payment is scheduled
          to be made. (vi) Once an Employee has elected the installment option
          provided in this paragraph 4(c), his entire Account balance will be
          transferred to the Fixed Income Fund.

Equity Fund, the Fixed Income Fund, or the Intermediate Term Investment Grade
Bond Fund, distributions shall be made in cash.  With respect to the portion of

be aggregated with the employer under Section 414(b), (c), (m), or (o) of the
Code.

(5)  OTHER DISTRIBUTIONS

     In the event that a loan made to a Participant under Article VIII is in
default and the Administrative Committee determines that it is necessary for a
distribution to be made under the Plan in order to cure such default and that
such a distribution could be made under the terms of this Plan and Section
165(e)(2) of the ITA, the Committee, with notice to the Participant, shall cause
a distribution to be made on behalf of the Participant under the Plan which
shall be applied by the Committee to the unpaid balance of the loan, including
accrued interest.  Such distribution shall be charged against the Participant's

                                      26

Administrator to be a qualified domestic relations order except that payments

employment, then his Account will not be distributed to him prior to his

                             LOANS TO PARTICIPANTS



(1)  AVAILABILITY OF LOANS TO PARTICIPANTS

     (a)  The Administrative Committee may, in its discretion and effective at
such time as it specifies, provide for the availability of loans from the Plan
to Employees on whose behalf CODA Contributions have been made and any other
Participant or Beneficiary who is a party in interest within the meaning of
Section 3(14) of ERISA.  If the Administrative Committee institutes such a loan
program, the loans shall be made pursuant to the provisions and limitations of
this Article.

     (b)  No loan shall be made by the Plan without the approval of the
Administrative Committee or its delegate, whose action thereon shall be final.
No loan shall be made to a Participant who is not an Employee of an Employing
Company or a party in interest within the meaning of Section 3(14) of ERISA at
the time the loan application is made to the Committee.

     (c)  The Administrative Committee may establish rules governing the
granting of loans, provided that such rules are not inconsistent with the
provisions of this Article and that loans are made available to all Participants
on a reasonably equivalent basis.  These rules may limit the number of loans a
Participant may receive, require payment of loan processing fees by the
Participant (either directly or out of his Account) or establish any other
requirements the Administrative Committee determines to be necessary or
desirable.

(2)  TERMS AND CONDITIONS OF LOANS TO PARTICIPANTS

     Any loan by the Plan to a Participant shall satisfy the following
requirements:

     (a)  Amount of Loan.  At the time the loan is made, the principal amount of
          --------------                                                        
the loan, plus the outstanding balance (principal plus accrued interest) due on
any other loans to the Participant from the Plan, shall not exceed the lesser of
(i) $50,000 or (ii) one-half of the value of the Participant's Account, or
$10,000 if larger.  The $50,000 limit shall be reduced by the highest
outstanding balance of all qualified retirement plan loans to the Participant
during the one-year period ending on the day before the date on which the loan
is made.  A "qualified retirement plan loan" is any loan from this Plan or any
other qualified retirement plan of the Employer.

     (b)  Investment Status of Loan.  Each loan shall be treated as an
          -------------------------                                   
investment of the Trust Fund as a whole or, if the Administrative Committee so
directs, as an investment of a specified portion of the Trust Fund, such as a
borrower's Account.

                                      29

 
     (c)  Application for Loan.  The Participant must give the Administrative
          --------------------
Committee adequate notice, as determined by the Committee, of the amount of the
loan being requested and the desired time for receiving the loan.  If a
Participant is married, his Spouse must consent in writing within the 90-day
period prior to the making of a loan.

     (d)  Length of Loan.
          -------------- 

          (i)  The Participant shall be required to repay the loan in
approximately equal installments of principal and interest over a period not in
excess of five years.  The five-year limit shall not apply to any loan the
proceeds of which are applied by the Participant to acquire, construct,
reconstruct, or substantially rehabilitate any dwelling unit that is to be used
within a reasonable time after the loan is made as the principal residence of
the Participant or of a member of his family.  In the latter case, the loan
shall be for a reasonable period, as determined by the Administrative Committee.

          (ii) The principal amount of the loan, together with all accrued
interest, shall, at the Plan Administrator's election, immediately become due
when the Participant is no longer an Employee of an Employing Company or a party
in interest under Section 3(14) of ERISA.

     (e)  Prepayment.  The Participant shall be permitted to repay the loan in
          ----------
whole or in part at any time prior to maturity, without penalty.

     (f)  Notes, Interest, and Withholding.  The Administrative Committee may
          --------------------------------                                   
require that the loan be evidenced by a promissory note executed by the
Participant and delivered to the Administrative Committee, and shall bear
interest at a reasonable rate determined by the Committee.  For this purpose,
the Committee will use a rate of interest which provides the Plan with a return
commensurate with the interest rates charged by persons in the business of
lending money for loans under similar circumstances.  Repayment of principal and
payment of interest will be made in installments not less frequently than
quarterly and normally will be effected through payroll withholding, and the
Participant shall execute any necessary documents to accomplish this as a
condition to approval of the loan.

     (g)  Security.  The loan shall be secured by an assignment of the
          --------                                                    
Participant's right, title and interest in and to his Account in the Plan.  No
more than 50% of the value of the Participant's Account balance may be used to
secure a loan. Security may be required in addition to that automatically
provided under this paragraph.

     (h)  Default.  When the Administrative Committee declares a loan to a
          -------                                                         
Participant to be in default the Administrative Committee shall take reasonable
steps to eliminate the default before causing a distribution to be made to the
Participant under the provisions of Section VII(5).

                                      30

 
          (i)  Other Terms and Conditions.  The Administrative Committee shall
               --------------------------                                     
fix such other terms and conditions of the loan as it deems necessary to comply
with legal requirements, to maintain the qualification of the Plan and Trust
under Section 165(a) of the ITA, to qualify as exempt from the prohibited
transaction rules of ERISA, or to prevent the treatment of the loan for tax
purposes as a distribution to the Participant.  The Committee, in its discretion
for any reason, may fix other terms and conditions of the loan, not inconsistent
with the provisions of this Article VIII.

     (j)  No Prohibited Transactions.  No loan shall be made unless such loan is
          --------------------------                                            
exempt from the tax imposed on prohibited transactions by Section 4975 of the
Code (or would be exempt from such tax if the Participant were a disqualified
person as defined in Section 4975(e)(2) of the Code) by reason of Section
4975(d)(1) of the Code.

Administrative Committee, and shall be fully protected in respect of any action
taken or omitted to be taken by them in good faith in reliance thereon; and any
action so taken or omitted shall be conclusive upon all persons affected
thereby.

(9)  INDEMNIFICATION AND INSURANCE

     To the extent permitted by law, the Employing Companies shall and do hereby
jointly and severally indemnify and agree to hold harmless any and all parties
protected under Section (8), from all loss, damage, or liability, joint or
several, including payment of expenses in connection with defense against any
such claim, for their acts, omissions and conduct, and for the acts, omissions
and conduct of their duly appointed agents, in the administration of the Plan,
which acts, omissions, or conduct constitutes or is alleged to constitute a
breach of such party's fiduciary or other responsibilities under ERISA or any
other law, except for those acts, omissions, or conduct resulting from his own
willful misconduct, willful failure to act, or gross negligence; provided,
however, that if any party would otherwise be entitled to indemnification
hereunder in respect of any liability and such party shall be insured against
loss as a result of such liability by any insurance contract or contracts, such
party shall be entitled to indemnification hereunder only to the extent by which
the amount of such liability shall exceed the amount thereof payable under such
insurance contract or contracts.

                                   ARTICLE X
               AMENDMENT, TERMINATION, MERGER, AND CONSOLIDATION


(1)  AMENDMENT OF PLAN

     The Corporation may, except as provided in Section (4), amend any or all
provisions of this Plan at any time by written instrument identified as an
amendment of the Plan effective as of a specified date.

(2)  TERMINATION OF PLAN

as provided in Section (4), the Corporation shall have the right at any time to
terminate the Plan in whole or in part by suspending or discontinuing
Contributions hereunder in whole or in part, or to otherwise terminate the Plan.
In accordance with any amendment to the Plan that may be adopted in connection
with any such termination, the Corporation may after such termination continue
the Plan and Trust in effect for the purpose of making distributions under the
Plan as they become payable, or may authorize the distribution of all or any
part of the assets of the Trust Fund as to which the Plan has been terminated.
In the event of termination the Committee shall continue to administer the Plan
and the Trustee shall continue to administer the Trust as herein provided for

or liabilities to any other plan and trust, each Participant and Beneficiary in
the Plan must be entitled to receive a benefit immediately after the merger,
consolidation or transfer, if such plan were then terminated, equal to or
greater than the benefit he would have been entitled to receive immediately
before the merger, consolidation, or transfer if the Plan had then been
terminated.  No merger, consolidation, or transfer shall take place unless such
other plan and trust are qualified under ITA Section 165(e), or if such.merger,
consolidation, or transfer would cause this Plan to cease to be a qualified
plan.

(4)  LIMITATION ON AMENDMENT OR TERMINATION

     (a)  The Corporation shall not have the power to amend or terminate the
Plan in such manner as would cause or permit any part of the assets of the Plan
held in the Trust Fund to be diverted to purposes other than for the exclusive
benefit of Participants and Beneficiaries, or as would cause or permit any
portion of such assets to revert to or become the property of the Employing
Companies, except as otherwise provided in Article XI(ll).  The Corporation
shall not have the right to modify or amend the Plan in

                                      35

 
such manner as to reduce the accrued benefit of any Participant or Beneficiary,
to deprive any Participant or Beneficiary of any benefit to which any one of
them was entitled under the Plan by reason of Contributions made prior thereto,
or adversely to affect the rights and duties of the Administrative Committee or
the Trustee without its consent in writing, unless such modification or
amendment is necessary to conform the Plan to, or to satisfy or continue to
satisfy the conditions of, any applicable law, including ERISA, governmental
regulations or rulings, or to cause the Plan to meet or to continue to meet the
requirements for qualification of the Plan under ITA Section 165(a), or any
similar statute enacted as a successor thereto.

                                   ARTICLE XI
                                CLAIMS PROCEDURE


(1)  CLAIMS FOR BENEFITS

     Any Participant or Beneficiary who shall believe that he has become
entitled to a benefit hereunder and who, after filing the application referred
to in Article VII(4), shall not have received, or commenced receiving, a
distribution of such benefit, pursuant to the provisions of Article VII, or who
shall believe that he is entitled to a benefit hereunder in excess of the
benefit that he shall have received, or commenced receiving, may file a written
claim for such benefit or increased benefit with the Administrative Committee at
any time up to the end of the calendar year next following the calendar year in
which he allegedly became entitled to receive a distribution of such benefit.
Such written claim shall set forth the Participant's or Beneficiary's name and
address and shall include a statement of the facts and a reference to the
pertinent provisions of the Plan upon which such claim is based.  Within ninety
(90) days after such claim is filed, the Committee shall provide the claimant
with written notice of its decision with respect to such claim. If such claim
shall be denied in whole or in part, the Committee shall, in such written notice
to the claimant, set forth in a manner calculated to be understood by the
claimant, the specific reason or reasons for denial; specific references to
pertinent provisions of the Plan upon which the denial is based; a description
of any additional material or information necessary for the claimant to perfect
his claim and an explanation as to why such material or information is
necessary; and an explanation of the provisions for review of claims set forth
in Section (2) of this Article.  If special circumstances require additional
time, the Committee may extend the period allowed for notice of its decision by
a period not to exceed ninety (90) days. Written notice of such extension,
stating the circumstances requiring the extension and the date by which a final
decision is expected, shall be provided to the claimant before the expiration of
the initial ninety (90) day period.  A claimant who shall not timely file his
claim as required shall to the extent permitted by law be conclusively deemed to
have waived any right to contest the determination of the Administrative
Committee.

(2)  REVIEW OF CLAIM

     A Participant or Beneficiary whose claim for benefits shall have been
denied may appeal such denial to the Vice President, Employee Benefits of the
Corporation and receive a full and fair review of his claim by filing with the
Vice President, Employee Benefits a written application for review at any time
within sixty (60) days after receipt from the Administrative Committee of the
written notice of denial of his claim provided for in Section (1).  A
Participant or Beneficiary who shall submit a timely written application for
review shall be entitled to review any and all documents pertinent to his claim
and may submit issues and comments to the Vice President, Employee Benefits in
writing.  In the discretion of the Vice President, Employee Benefits a hearing
may be held.  Not

                                      37

 
later than sixty (60) days after receipt of a written application for review,
the Vice President of Employee Benefits shall give the claimant written notice
of his decision on review, which shall set forth in a manner calculated to be
understood by the claimant specific reasons for his decision and specific
references to the pertinent provisions of the Plan upon which the decision is
based.  If special circumstances, including but not limited to the need for a
hearing as determined by the Vice President of Employee Benefits, shall require
additional time for making a decision on review, the period for decision may be
extended by not more than sixty (60) days.  Written notice of such extension,
stating the circumstances requiring the extension and the date by which a final
decision is expected, shall be provided to the claimant before the expiration of
the initial sixty (60) day period.  Even if the period for decision is extended
under this Section, a decision shall be made as soon as possible.  The decision
of the Vice President, Employee Benefits shall, to the extent permitted by law,
be final and binding on all parties.

                                      38

 
                                  ARTICLE XII
                                 MISCELLANEOUS


(1)  PROHIBITION AGAINST ALIENATION

     Except as otherwise provided in this Plan, no Participant or Beneficiary
shall have any right to withdraw, assign (either at law or in equity), pledge,
transfer, appropriate, encumber, commute, alienate, or anticipate his interest
in the Plan and Trust, or any payments to be made hereunder, and no benefits,
payments, rights, or interest of such a person under the Plan shall be in any
way subject to any legal or equitable process to levy or execute upon, charge,
garnish, or attach the same for payment of any claim against such person except
pursuant to a Qualified Domestic Relations Order, nor shall any such person have
any right of any kind whatsoever with respect to the Plan and Trust, or any
estate or interest therein, or with respect to any other property or rights,
other than the right to receive such distributions as are made out of the Trust,
as and when the same are or shall become due and payable under the terms of the
Plan.  Any attempt to transfer, pledge, or levy upon or otherwise alienate an
interest of a Participant or Beneficiary shall be invalid unless made pursuant
to a Qualified Domestic Relations Order.

(2)  RELATIONSHIP BETWEEN EMPLOYING COMPANY AND EMPLOYEES

     The adoption and maintenance of the Plan shall not be deemed to constItute
or modify a contract between any Employer and any Employee or Participant or to
be a consideration or inducement for or condition of the performance of services
by any person.  Nothing herein contained shall be deemed to give to any Employee
or Participant the right to continue in the service of any Employer, to
interfere with the right of an Employer to discharge any Employee or Participant
at any time, or to give an Employer the right to require an Employee or
Participant to remain in its service or to interfere with his right to terminate
his service at any time.

(3)  PARTICIPANTS' BENEFIT LIMITED TO ASSETS

     Each Participant, by his participation in the Plan and Trust, shall be
conclusively deemed to have agreed to look solely to the Trust Fund, and not to
any other person, entity, or assets for the payment of any benefit to which he
may be entitled by reason of his participation, and to have consented to all of
the terms and conditions of the Plan, as the same may be amended from time to
time, and shall be bound thereby with the same force and effect as if he were a
party to this Plan.

                                      39

 
(4)  TITLES AND HEADINGS

     The titles and headings of the articles and sections in this Plan are
placed herein for convenience of reference only, and in case of any conflicts,
the text of this Plan, rather than the titles or headings, shall control.

(5)  GENDER AND NUMBER

     The masculine pronoun, wherever used herein, shall include the feminine
pronoun, and the singular shall include the plural, except where the context
requires otherwise.

(6)  APPLICABLE LAW

     The provisions of this Plan shall be construed according to the laws of the
Commonwealth of Puerto Rico, except to the extent that they are preempted by
ERISA, or by other federal law.  The Plan is intended to comply with ERISA and
the ITA, and to contain a qualified cash or deferred arrangement within the
meaning of ITA Section 165 (e), and shall be interpreted and construed
accordingly.

(7)  INABILITY TO LOCATE PAYEE

     Anything to the contrary herein notwithstanding, if the Administrative
Committee is unable, after a reasonable effort, to locate any Participant or
Beneficiary to whom an amount is distributable hereunder, such amount shall be
forfeited.  Notwithstanding the foregoing, however, such amount shall be
reinstated, by means of an additional Contribution by the Corporation if and
when a valid claim for the forfeited amount is subsequently made by the
Participant or Beneficiary or if the Administrative Committee receives proof of
death of such person, satisfactory to the Committee; in such case, payment of
the reinstated amount shall be made in accordance with the provisions of this
Plan.  No such additional Contribution shall reduce the Matching Contributions
otherwise required.  Any benefits lost by reason of applicable state law
relating to associate or abandoned property shall be considered forfeited but
shall not be subject to reinstatement.

(8)  INCOMPETENCE OF PAYEE

     In the event any benefit is payable to a minor or incompetent, to a person
otherwise under legal disability, or to a person who, in the sole judgment of
the Administrative Committee is by reason of advanced age, illness, or other
physical or mental incapacity incapable of handling the disposition of his
property, the Committee may direct the Trustee to apply the whole, or any part
of such benefit, directly to the care, comfort, maintenance, support, education,
or use of such person, or pay or distribute the whole or any part of such
benefit to (a) the parent of such person, (b) the guardian, committee, or other
legal representative, wherever appointed, of such person, (c) the

                                      40

 
person with whom such person resides, (d) any person having the care and control
of such person, or (e) such person personally.  The receipt by the person to
whom any such payment or distribution is so made shall constitute a full and
complete discharge of the right of affected Participants, former Participants,
and Beneficiaries under the Plan.

(9)  DEALING WITH THE TRUSTEE

     No person dealing with the Trustee shall be obliged to see to the
application of any property paid or delivered to the Trustee or to inquire into
the expediency or propriety of any transaction or the Trustee's authority to
consummate the same, except as may specifically be required of such person under
ERISA.

(10) RETURN OF CONTRIBUTIONS

     (a)  All Contributions to the Plan are expressly conditioned on the
qualification, and continued qualification, of the Plan under Section 165 of the
ITA, and if such qualification shall be denied, the Participants (with respect
to Thrift Contributions) and the Corporation (with respect to all other
Contributions) shall be entitled to receive a return of Contributions made after
the effective date of such denial, net of any losses attributable thereto and
together with any earnings thereon, as soon as practicable but in any event
within one year after the denial of qualification of the Plan.

     (b)  The Corporation's Contributions to the Plan are conditioned upon the
deductibility of such Contributions under Section 404 of the Code and Section
23(p) of the ITA for the taxable year for which made, and the Corporation shall
be entitled to receive a return of any Contribution, net of any losses
attributable thereto, to the extent its deduction is deduction is disallowed,
within one year after such disallowance.

     (c)  If a Contribution is made to the Plan by the Corporation and/or a
Participant by a mistake of fact, the Corporation and/or such Participant shall
be entitled to receive a return of such Contribution, net of any losses
attributable thereto and, in the case of a Participant, together with any
earnings thereon, within one year after the making of such Contribution.

                                      41

 
(11) SEPARABILITY

     If any provision of this Plan is found, held or deemed to be void,
unlawful, or unenforceable under any applicable statute or other controlling
law, the remainder of this Plan shall continue in full force and effect.

          IN WITNESS WHEREOF this amended and restated Plan was
executed as of April 4, 1993.

          Re:  Martin Marietta Corporation Performance Sharing
               Plan for Puerto Rico Employees (the "Plan")

Ladies and Gentlemen:

      I submit this opinion to you in connection with the filing with the 
Securities and Exchange Commission of a registration statement on Form S-8 (the 
"Registration Statement") on the date hereof. The Registration Statement 
registers shares of common stock ("Common Stock") of Lockheed Martin Corporation
(the "Corporation") for use in connection with the Plan. The Plan contemplates 
that Common Stock may be treasury or authorized but unissued shares or may be 
acquired in the open market. As Assistant General Counsel of the Corporation, I 
have examined such corporate records, certificates and other documents and have 
reviewed such questions of law as I deemed necessary or appropriate for the 
purpose of this opinion.

      Based upon that examination and review, I advise you that in my opinion:

      (i)  the Corporation has been duly incorporated and is validly existing 
           under the laws of the State of Maryland; and

      (ii) to the extent that the operation of the Plan results in the issuance
           of Common Stock, such shares of Common Stock have been duly and
           validly authorized and, when issued in accordance with the terms set
           forth in the Registration Statement, will be legally issued, fully
           paid and nonassessable.

      I hereby consent to the filing of this opinion as an exhibit to the 
Registration Statement and to the reference to my opinion in the Registration 
Statement.

                                           Very truly yours,

                                           /s/ Stephen M. Piper
