Item 3. INCORPORATION OF DOCUMENTS BY REFERENCE
        ---------------------------------------


        The SEC allows us to incorporate by reference the information we file
with them, which means:


        -    incorporated documents are considered part of the prospectus;


        -    we can disclose important information to you by referring you to
             those documents; and


        -    information that we file with the SEC will automatically update and
             supersede this incorporated information.


        We incorporate by reference the documents listed below which were filed
with the SEC under the Securities Exchange Act of 1934:


        (a)  Our Annual Report on Form 10-K for the fiscal year ended December
31, 2000;

        (b)  The description of our Common Stock, par value $1.00 per share,
contained in our Quarterly Report on Form 10-Q for the quarter ended September
30, 1991.

        (c)  The description of the Series A Participating Cumulative Preferred
Stock Purchase Rights contained in our Form 8-A dated February 21, 1996.

        We also incorporate by reference each of the following documents that we
will file with the SEC after the date of this registration statement until this
offering is completed:

        -    reports filed under Section 13(a) and (c) of the Securities
             Exchange Act of 1934;

        -    definitive proxy or information statements filed under Section 14
             of the Securities Exchange Act of 1934 in connection with any
             subsequent stockholders' meeting; and

        -    any reports filed under Section 15(d) of the Securities Exchange
             Act of 1934.


Item 4. DESCRIPTION OF SECURITIES
        -------------------------

        Not applicable; the class of securities to be offered is registered
under Section 12(g) of the Securities Exchange Act of 1934.


Item 5. INTEREST OF NAMED EXPERTS AND COUNSEL
        -------------------------------------

        The validity of the newly issued shares of Common Stock of the Company
will be passed upon by J.M. Jackson, Jr., Vice President, General Counsel and
Secretary. Mr. Jackson owns


shares of the Company directly, and through various employee benefit plans, and
has options to purchase shares.


Item 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS
        -----------------------------------------

        The Virginia Stock Corporation Act permits indemnification of the
Company's directors, officers and employees in a variety of circumstances. Under
Sections 13.1-697 and 13.1-702 of the Virginia Stock Corporation Act, a Virginia
corporation generally is authorized to indemnify its directors, officers and
employees in civil or criminal actions if they acted in good faith and believed
their conduct to be in the best interests of the corporation. In the case of
criminal actions, directors, officers or employees will be indemnified if they
had no reasonable cause to believe that their conduct was unlawful. The Act also
provides mandatory indemnification in Section 13.1-698 for a director against
expenses incurred in the successful defense of a proceeding. Under Section 13.1-
704 of the Virginia Stock Corporation Act, a Virginia corporation is permitted
to grant such further indemnity to its directors, officers and employees as may
be authorized by the articles of incorporation or any bylaw or resolution
adopted by its shareholders unless those persons engaged in willful misconduct
or a knowing violation of the criminal law. The Company's By-laws require
indemnification of directors, officers and employees with respect to certain
liabilities, expenses and other amounts imposed upon them by reason of having
been directors, officers or employees unless they engaged in willful misconduct
or a knowing violation of the criminal law. The Company's Board of Directors or,
under certain circumstances, legal counsel make the determination of whether a
director, officer or employee met the standard of conduct required for
indemnification. Section 13.1-692.1 of the Virginia Stock Corporation Act
permits a Virginia corporation to limit or totally eliminate the liability of a
director or officer for monetary damages in a shareholder or derivative
proceeding unless that director or officer engaged in willful misconduct or a
knowing violation of the criminal law or securities laws. The Company's By-laws
contain a provision intended to eliminate such liability.


        Directors and officers of the Company are insured, subject to certain
exclusions and limits and to the extent not otherwise indemnified by the
Company, against loss (including expenses incurred in the defense of actions,
suits and proceedings in connection therewith) arising from any error,
misstatement, misleading statement, omission or other act made or performed in
their capacity as directors and officers.  The policies also reimburse the
Company for liability incurred in the indemnification of its directors and
officers under common or statutory laws or the Company's By-laws, subject to the
terms, conditions and exclusions of such policies.  In addition, directors,
officers and other employees of the Company who may be "fiduciaries" as that
term is used in the Employee Retirement Income Security Act of 1974 are insured
with respect to liabilities under the Act.


Item 7. EXEMPTION FROM REGISTRATION CLAIMED
        -----------------------------------

       Not applicable.


Item 8. EXHIBITS
        --------

        (a)  The Exhibits to this Registration Statement are listed in the
Exhibit Index to this Registration Statement, which Index is incorporated herein
by reference.

        (b)  The Registrant undertakes that it or its subsidiary will submit or
has submitted the plan and any amendment thereto to the Internal Revenue Service
("IRS") in a timely manner, and has made or will make all changes required by
the IRS in order to qualify the plan.

Item 9. UNDERTAKINGS
        ------------

        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;

             (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; provided that, notwithstanding the foregoing any
                   increase or decrease in volume of securities offered (if the
                   total dollar value of securities offered would not exceed
                   that which was registered) and any deviation from the low or
                   high end of the estimated maximum offering range may be
                   reflected in the form of prospectus filed with the Commission
                   pursuant to Rule 424(b) if, in the aggregate, the changes in
                   volume and price represent no more than a 20 percent change
                   in the maximum aggregate offering price set forth in the
                   "Calculation of Registration Fee" table in the effective
                   registration statement; and

             (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 paragraphs (i) and (ii) above do not
                   apply if the registration statement is on Form S-3 or Form S-
                   8, and the information required to be included in a post-
                   effective amendment by those paragraphs is contained in
                   periodic reports filed with or furnished to the Commission by
                   the Registrant pursuant to section 13 or 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 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 provisions referred to under Item 6,
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 Securities Act of 1933 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 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
Securities Act of 1933 and will be governed by the final adjudication of such
issue.

Registration Statement to be signed on its behalf by the undersigned, thereunto
