ITEM 4.          DESCRIPTION OF SECURITIES.

                 Not applicable.


ITEM 5.          INTERESTS OF NAMED EXPERTS AND COUNSEL.

                 Not applicable.


ITEM 6.          INDEMNIFICATION OF DIRECTORS AND OFFICERS.

                 The Registrant's Articles of Incorporation, as amended,
provide that the Registrant shall indemnify its directors and officers whether
serving the Registrant or, at the Registrant's request, another entity, to the
fullest extent required or permitted by the general laws of the State of
Maryland now or hereafter in force, including the advance of expenses under the
procedures provided by such laws.  The Registrant's Articles of Incorporation
also provide that the Registrant shall indemnify its other agents or employees,
whether serving the Registrant, or at its request, another entity, to such
extent as is authorized by the Board of Directors or the By-laws of the
Registrant and as permitted by law.

         The Maryland General Corporation Law provides that a corporation may
indemnify any director made a party to a proceeding by reason of service in
that capacity unless it is established that: (1) the act or omission of the
director was material to the matter giving rise to the proceeding and (a) was
committed in bad faith or (b) was the result of active and deliberate
dishonesty, or (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 had reasonable cause to believe that the act or omission was
unlawful.  To the extent that a director has been successful in defense of any
proceeding, the Maryland General Corporation Law provides that he or she shall
be indemnified against reasonable expenses incurred in connection therewith.  A
Maryland corporation may indemnify its officers to the same extent as its
directors and to such further extent as is consistent with law.

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 Securities Act of 1933 (the "Securities Act");

                          (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.

                 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 Exchange Act that are incorporated by reference in the
Registration Statement.

                 (2) That, for the purpose of determining any liability under
the Securities Act, 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.
<PAGE>   5
                 The undersigned Registrant hereby undertakes that, for
purposes of determining any liability under the Securities Act, each filing of
the Registrant's annual report pursuant to section 13(a) or section 15(d) of
the Exchange Act (and, where applicable, each filing of an employee benefit
plan's annual report pursuant to section 15(d) of the Exchange Act) 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.

Insofar as indemnification for liabilities arising under the Securities Act 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 Commission such indemnification is against
public policy as expressed in the Securities 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.


                                   SIGNATURES

                 Pursuant to the requirements of the Securities Act, 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 City of Beltsville, County of Prince Georges, Maryland
on this 31 day of May, 1996.

                                          Registrant's fiscal year ended June

                                          Registrant's Registration Statement

ITEM 4.          DESCRIPTION OF SECURITIES.

                 Not applicable.

ITEM 5.          INTERESTS OF NAMED EXPERTS AND COUNSEL.

                 Not applicable.

ITEM 6.          INDEMNIFICATION OF DIRECTORS AND OFFICERS.

                 The Registrant's Articles of Incorporation, as amended,
provide that the Registrant shall indemnify its directors and officers whether
serving the Registrant or, at the Registrant's request, another entity, to the
fullest extent required or permitted by the general laws of the State of
Maryland now or hereafter in force, including the advance of expenses under the
procedures provided by such laws.  The Registrant's Articles of Incorporation
also provide that the Registrant shall indemnify its other agents or employees,
whether serving the Registrant, or at its request, another entity, to such
extent as is authorized by the Board of Directors or the By-laws of the
Registrant and as permitted by law.

         The Maryland General Corporation Law provides that a corporation may
indemnify any director made a party to a proceeding by reason of service in
that capacity unless it is established that: (1) the act or omission of the
director was material to the matter giving rise to the proceeding and (a) was
committed in bad faith or (b) was the result of active and deliberate
dishonesty, or (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 had reasonable cause to believe that the act or omission was
unlawful.  To the extent that a director has been successful in defense of any
proceeding, the Maryland General Corporation Law provides that he or she shall
be indemnified against reasonable expenses incurred in connection therewith.  A
Maryland corporation may indemnify its officers to the same extent as its
directors and to such further extent as is consistent with law.

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 Securities Act of 1933 (the "Securities Act");

                          (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.

                 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 Exchange Act that are incorporated by reference in the
Registration Statement.

                 (2) That, for the purpose of determining any liability under
the Securities Act, 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.
5
                 The undersigned Registrant hereby undertakes that, for
purposes of determining any liability under the Securities Act, each filing of
the Registrant's annual report pursuant to section 13(a) or section 15(d) of
the Exchange Act (and, where applicable, each filing of an employee benefit
plan's annual report pursuant to section 15(d) of the Exchange Act) 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.

Insofar as indemnification for liabilities arising under the Securities Act 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 Commission such indemnification is against
public policy as expressed in the Securities 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.

                                   SIGNATURES

                 Pursuant to the requirements of the Securities Act, 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 City of Beltsville, County of Prince Georges, Maryland
on this 31 day of May, 1996.
