Item 5.          Interests of Named Experts and Counsel.

         Not Applicable.

Item 6.          Indemnification of Directors and Officers.

         Section 2-418 of the Maryland General Corporation Law provides for the
indemnification of directors and officers of a corporation incorporated under
Maryland law under certain circumstances.  A person who was or is a director or
officer of the corporation may be indemnified by the corporation for judgments,
penalties, fines, settlements and reasonable expenses (including attorneys'
fees) actually incurred by the director or officer in connection with any
threatened, pending or completed action, suit or proceeding, whether civil,
criminal, administrative or investigative, to which such director or officer
was or is made a party by reason of service in that capacity unless it is
established that (1) the act or omission of the director or officer was
material to the matter giving rise to the proceeding and (i) was committed in
bad faith or (ii) was the result of active and deliberate dishonesty; (2) the
director actually received an improper personal benefit in money, property or
services; or (3) in the case of any criminal proceeding, the director or
officer had reasonable cause to believe that the act or omission was unlawful.
If a proceeding is brought by or on behalf of the corporation, no
indemnification will be made in connection with such proceeding if the director
or officer was adjudged to be liable to the corporation.

         Article Eighth of the Articles of Incorporation of the Registrant
provides that the Registrant shall indemnify its directors and officers to the
full extent permitted by Maryland Law now or hereafter in force, including the
advance of related expenses, upon a determination by the Board of Directors or
independent legal counsel made in accordance with applicable statutory
standards, and that the Registrant, upon authorization by the Board of
Directors, may indemnify other employees or agents to the same extent. Article
Ninth also contains a provision that eliminates the liability of officers and
directors of the Registrant for money damages to the Registrant or its
stockholders for any act or omission, including conduct of such officers and
directors on behalf of the Registrant constituting gross negligence, unless (1)
the director or officer received an improper benefit in money, property or
services or (2) the action, or failure to act, by the director or officer was
the result of active and deliberate dishonesty which was material to a cause of
action adjudicated in a proceeding against such director or officer.

         Article VIII of the By-Laws of the Registrant provides for the
indemnification of the Registrant's directors and officers.  The Registrant has
an insurance policy indemnifying its officers and directors against claims and
liabilities (with stated exceptions) to which they may become subject by reason
of their positions as directors and officers.

         Insofar as indemnification for liabilities arising under the
Securities Act of 1933 (the 'Securities Act')may be permitted to directors,
officers or persons controlling the Registrant pursuant to the foregoing
provisions, the Registrant has been informed that in the opinion of the
Securities and Exchange Commission such indemnification is against public
policy as expressed in the Securities Act and is therefore unenforceable.

Item 7.          Exemption from Registration Claimed.

         Not Applicable.

Item 8.          Exhibits.

         The following documents are filed as exhibits to this Registration
Statement:

                 5.1      Opinion of David C. Jones regarding 3,000,000 shares
                          of Common Stock.

                 24.1     Consent of independent public accountants to

                 24.2     Consent of counsel (included in the opinion of David
                          C. Jones filed herewith as Exhibit 5.1).

Item 9.          Undertakings.

         The 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 this 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 this
                 Registration Statement; and

                          (iii)  To include any material information with
                 respect to the plan of distribution not previously disclosed
                 in this Registration Statement or any material change to such
                 information in this Registration Statement;

         provided, however, that paragraphs (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 this
         Registration Statement.
<PAGE>   5
                 (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.

                 (4)  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 that is incorporated by reference in this 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.

                 (5)  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 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.

Item 4.          Description of Securities.

         Not Applicable.
3
Item 5.          Interests of Named Experts and Counsel.

         Not Applicable.

Item 6.          Indemnification of Directors and Officers.

         Section 2-418 of the Maryland General Corporation Law provides for the
indemnification of directors and officers of a corporation incorporated under
Maryland law under certain circumstances.  A person who was or is a director or
officer of the corporation may be indemnified by the corporation for judgments,
penalties, fines, settlements and reasonable expenses (including attorneys'
fees) actually incurred by the director or officer in connection with any
threatened, pending or completed action, suit or proceeding, whether civil,
criminal, administrative or investigative, to which such director or officer
was or is made a party by reason of service in that capacity unless it is
established that (1) the act or omission of the director or officer was
material to the matter giving rise to the proceeding and (i) was committed in
bad faith or (ii) was the result of active and deliberate dishonesty; (2) the
director actually received an improper personal benefit in money, property or
services; or (3) in the case of any criminal proceeding, the director or
officer had reasonable cause to believe that the act or omission was unlawful.
If a proceeding is brought by or on behalf of the corporation, no
indemnification will be made in connection with such proceeding if the director
or officer was adjudged to be liable to the corporation.

         Article Eighth of the Articles of Incorporation of the Registrant
provides that the Registrant shall indemnify its directors and officers to the
full extent permitted by Maryland Law now or hereafter in force, including the
advance of related expenses, upon a determination by the Board of Directors or
independent legal counsel made in accordance with applicable statutory
standards, and that the Registrant, upon authorization by the Board of
Directors, may indemnify other employees or agents to the same extent. Article
Ninth also contains a provision that eliminates the liability of officers and
directors of the Registrant for money damages to the Registrant or its
stockholders for any act or omission, including conduct of such officers and
directors on behalf of the Registrant constituting gross negligence, unless (1)
the director or officer received an improper benefit in money, property or
services or (2) the action, or failure to act, by the director or officer was
the result of active and deliberate dishonesty which was material to a cause of
action adjudicated in a proceeding against such director or officer.

         Article VIII of the By-Laws of the Registrant provides for the
indemnification of the Registrant's directors and officers.  The Registrant has
an insurance policy indemnifying its officers and directors against claims and
liabilities (with stated exceptions) to which they may become subject by reason
of their positions as directors and officers.

         Insofar as indemnification for liabilities arising under the
Securities Act of 1933 (the 'Securities Act')may be permitted to directors,
officers or persons controlling the Registrant pursuant to the foregoing
provisions, the Registrant has been informed that in the opinion of the
Securities and Exchange Commission such indemnification is against public
policy as expressed in the Securities Act and is therefore unenforceable.

Item 7.          Exemption from Registration Claimed.

         Not Applicable.

Item 8.          Exhibits.

         The following documents are filed as exhibits to this Registration
Statement:

                 4.1      1993 Stock Option Plan of Lafarge Corporation

                 5.1      Opinion of David C. Jones regarding 3,000,000 shares
                          of Common Stock.

                 24.1     Consent of independent public accountants to
                          incorporation of reports by reference.

                 24.2     Consent of counsel (included in the opinion of David
                          C. Jones filed herewith as Exhibit 5.1).

Item 9.          Undertakings.

         The 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 this 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 this
                 Registration Statement; and

                          (iii)  To include any material information with
                 respect to the plan of distribution not previously disclosed
                 in this Registration Statement or any material change to such
                 information in this Registration Statement;

         provided, however, that paragraphs (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 this
         Registration Statement.
5
                 (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.

                 (4)  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 that is incorporated by reference in this 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.

                 (5)  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 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.
