reference pursuant to this Item 3.

ITEM 4.  DESCRIPTION OF SECURITIES

         The following is a summary description of certain of the Company's
securities, and is not intended, and should not be relied upon, as exhaustive.
The description is subject in all respects to the Company's Restated Articles
of Incorporation, the Certificate of Designation, Preferences, Rights and
Limitations of the Company's Series A preferred stock, par value $10.00 per
share (the "Series A Preferred Stock"), and the Rights Agreement dated as of
March 31, 1990 between the Company and Continental Stock Transfer & Trust
Company, as Rights Agent (the "Rights Agreement").  The information set forth
herein is qualified in its entirety by the foregoing reference.

COMMON STOCK

         The Company is authorized by its Restated Articles of Incorporation to
issue 50,000,000 shares of Common Stock of which 35,150,238 shares were issued
and outstanding as of February 3, 1994.  An additional 2,598,668 shares were
reserved for issuance upon the conversion, exchange or exercise of other
outstanding securities or pursuant to various employee benefit plans of the
Company.  As of such date there were 3,789 holders of record of Common Stock.

         VOTING RIGHTS.  The holders of Common Stock are entitled to one vote
for each share held on all matters submitted to a vote of common stockholders.
The Common Stock does not have cumulative voting rights; accordingly, the
holders of a majority of the shares of Common Stock outstanding may elect all
of the nominees for election to the Company's Board of Directors if they choose
to do so.  In such event, the holders of the remaining shares of Common Stock
would not be able to elect any such nominees.

         DIVIDENDS.  Each share of Common Stock is entitled to participate
equally in dividends, if, as and when declared by the Board of Directors, and
in the distribution of assets in the event of liquidation, subject in all cases
to any prior rights of outstanding shares of the Company's preferred stock.
The shares of Common Stock have no preemptive or conversion rights, redemption
provisions or sinking fund provisions.  The outstanding shares of Common Stock
are duly and validly issued, fully paid and nonassessable.





                                      -2-
<PAGE>   3
         LISTING.  The Common Stock is listed for trading on the New York Stock
Exchange.

         TRANSFER AGENT AND REGISTRAR.  Continental Stock Transfer & Trust
Company is the Transfer Agent and Registrar of the Common Stock.

PREFERRED STOCK

         Pursuant to the Company's Restated Articles of Incorporation, the
Company is authorized to issue 5,000,000 shares of preferred stock, and the
Company's Board of Directors by resolution may establish one or more series of
preferred stock having such number of shares, designations, relative voting
rights, dividend rights, liquidation and other rights, preferences and
limitations as may be fixed by the Board of Directors without further
stockholder approval.  The Board of Directors has established the Series A
Preferred Stock with 900,000 authorized shares, none of which were outstanding
as of May 13, 1994.  See "Series A Junior Participating Preferred Stock" below.

PROVISIONS OF THE RESTATED ARTICLES OF INCORPORATION WHICH MAY DELAY OR PREVENT
A CHANGE IN CONTROL

         The provisions of the Company's Restated Articles of Incorporation
summarized in the succeeding paragraphs may delay, defer or prevent a tender
offer or takeover attempt that a stockholder might consider to be in such
stockholder's best interest, including those attempts that might result in a
premium price for the shares held by stockholders.

         The Board of Directors of the Company is divided into three classes
that are elected for staggered three-year terms.  Stockholders may remove a
director at any time, with or without cause, but only by the affirmative vote
of the holders of at least 70% of the outstanding shares of capital stock
entitled to vote for the election of directors; provided, that if the Board of
Directors, by an affirmative vote of at least 80% of the entire Board of
Directors, recommends removal of a director to the shareholders, such removal
may be effected by the affirmative vote of the holders of a majority of the
outstanding shares of capital stock entitled to vote on the election of
directors.

         Pursuant to the Company's Restated Articles of Incorporation, the
Board of Directors by resolution may establish one or more series of Preferred
Stock having such number of shares, designations, relative voting rights,
dividend rights, and liquidation and other rights, preferences and limitations
as may be fixed by the Board of Directors without further stockholder approval.
Such rights, preferences, privileges and limitations as may be established
could have the effect of impeding or discouraging the acquisition of control of
the Company.

         The Company's Restated Articles of Incorporation contain a "fair
price" provision that requires the approval of holders of not less than 66 2/3%
of the outstanding shares of capital stock of the Company entitled to vote in
the election of directors not owned, directly or indirectly, by Control Persons
(as defined below) as a condition for mergers, consolidations and other
business combinations involving the Company and any Control Persons; provided
that the 66 2/3% voting requirement is not applicable if:

         (a)     the business combination is solely between the Company and
another corporation of which 50% or more of the voting stock is owned by the
Company and none of which is owned by a Control Person and each holder of
Common Stock receives the same type of consideration in proportion to his
holdings; or

         (b)     all of the following conditions are satisfied:

                 (i)      the cash or reasonably determined fair market value
         of the property, securities or other consideration to be received per
         share in the business combination by holders of the Common Stock is
         not less than the highest price per share paid by the Control Person
         in acquiring any of its holdings of Common Stock;





                                      -3-
<PAGE>   4
                 (ii)     after becoming a Control Person and before the
         consummation of the business combination;

                          (A)     the Control Person has not acquired any newly
                 issued shares of capital stock, directly or indirectly, from
                 the Company (except upon conversion of convertible securities
                 acquired before becoming a Control Person or as a result of a
                 pro-rata stock dividend or stock split or upon compliance with
                 the provisions of the Company's Restated Articles of
                 Incorporation); and

                          (B)     the Control Person has not received the
                 benefit, directly or indirectly (except proportionately as a
                 shareholder), of any loans, advances, guarantees, pledges or
                 other financial assistance or tax credits provided by the
                 Company or made any major changes in the Company's business or
                 equity capital structure; and

                 (iii)    a proxy statement responsive to the requirements of
         the Exchange Act, regardless of whether the Company is then subject to
         such requirements, is mailed to the public shareholders in the Company
         for the purpose of soliciting shareholder approval of such business
         combination; or

         (c)     the business combination is approved by the affirmative vote
of at least a majority of the directors who held office as directors before the
date on which the Control Person became such.

         Control Persons include any holder of 20% or more of the outstanding
shares of Common Stock and any affiliate of such holder.

         The Company's Restated Articles of Incorporation further provide that
special meetings of stockholders can be called only by the chairman of the
board, the president, the Board of Directors, or by the holders of 50% of the
shares of capital stock of the Company entitled to vote at the proposed special
meeting.

SHAREHOLDER RIGHTS PLAN

         On June 20, 1990, the Board of Directors of the Company declared a
dividend distribution of one preferred stock purchase right ("Right") for each
outstanding share of Common Stock.  Each right entitles the registered holder
to purchase from the Company one Depositary Preferred Share, which represents
equitable ownership of one one-thousandth of a share of Series A Preferred
Stock at a price of $80.00 per Depositary Preferred Share (the "Exercise
Price"), subject to adjustment.

         The Rights attach to all certificates representing outstanding or
later issued shares of Common Stock, and no separate Rights certificates have
been distributed.  Until the earlier to occur of (i) 10 calendar days (subject
to extension by the Board of Directors) following a public announcement that a
person or group of affiliated or associated persons has acquired beneficial
ownership of 20% or more of the outstanding shares of Common Stock (an
"Acquiring Person"); or (ii) 10 business days (subject to extension by the
Board of Directors) following a public announcement of a tender or exchange
offer, which, if consummated, would result in an Acquiring Person beneficially
owning 20% or more of the shares of Common Stock (the earlier to occur of such
dates is referred to hereafter as the "Distribution Date"), or earlier
redemption or expiration of the Rights, (a) the Rights will be evidenced with
respect to any of the Common Stock certificates outstanding as of July 2, 1990
by the certificates representing such shares and shall be transferred with and
only with the Common Stock; (b) new Common Stock certificates will contain a
notation incorporating the Rights Agreement by reference; and (c) the surrender
for transfer of any certificates representing shares of Common Stock
outstanding also will constitute the transfer of the Rights associated with
such shares of Common Stock.  As soon as practicable following the Distribution
Date, separate certificates representing the Rights ("Rights Certificates")
will be mailed to holders of record of Common Stock as of the close of business
on the Distribution Date.  Thereafter, the Rights Certificates alone will
evidence the Rights, and the Rights will be transferable separate and apart
from the Common Stock.





                                      -4-
<PAGE>   5
         The Rights are not exercisable until the Distribution Date.  Under
certain circumstances set forth in the Rights Agreement, Rights issued to, or
beneficially owned by, a person who is or becomes an Acquiring Person, its
affiliate, or associate, as defined in the Rights Agreement, will become null,
void, and non-transferable.  The Rights will expire at the close of business on
March 31, 2000, unless earlier redeemed by the Board of Directors as described
below.

         The aggregate number of shares of Series A Preferred Stock issuable
upon the exercise of the Rights will be deposited, if, as and when issued, with
Continental Stock Transfer & Trust Company, as depositary (the "Depositary")
under the Depositary Agreement between the Company and the Depositary.  The
Depositary will issue, upon written order, Depositary Receipts, each of which
will represent one or more Depositary Preferred Shares.  Each Depositary
Preferred Share will represent the equitable ownership of one one-thousandth of
a share of Series A Preferred Stock, and will entitle the holder to cast one
vote on all matters upon which the holders of Series A Preferred Stock will be
entitled to vote.

         The Exercise Price payable and the number of Depositary Preferred
Shares properly issuable upon the exercise of the Rights are subject to
adjustment from time to time to prevent dilution (i) in the event of a dividend
payable in, or subdivision or combination of, the Common Stock; (ii) upon the
grant to holders of the Common Stock of rights, options, or warrants entitling
the holder to subscribe for or purchase Common Stock, or securities convertible
into Common Stock, at an exercise price per share of Common Stock less than the
then current market price per share of Common Stock; or (iii) upon the
distribution of evidences of indebtedness, cash (other than a regular periodic
cash dividend out of the retained earnings of the Company), assets (other than
a dividend payable in Common Stock, but including a dividend payable in stock
other than Common Stock) or convertible securities, subscription rights, or
warrants (other than those referred to in clause (ii) above).

         At any time after a person becomes an Acquiring Person, the Board of
Directors may, at its option, exchange all or part of the then outstanding and
exercisable Rights for shares of Common Stock at an exchange ratio of one share
of Common Stock per Right; provided, that the Board of Directors may not effect
such an exchange after the time that any Acquiring Person together with its
affiliates and associates (each as defined in the Rights Agreement) becomes the
beneficial owner of 50% or more of the then outstanding shares of Common Stock.

         If, after any person has become an Acquiring Person, (i) the Company
is acquired in a merger or other business combination transaction, or its
Common Stock is changed into or exchanged for other securities or assets, or
(ii) more than 50% of the Company's assets or earning power is sold, each Right
will entitle the holder to purchase, upon the exercise thereof at the then
current Exercise Price, a number of shares of common stock of the acquiring
company having a market price (as defined in the Rights Agreement) of two times
the Exercise Price.  If any person or group becomes the beneficial owner of 20%
or more of outstanding shares of Common Stock, then each holder (other than an
Acquiring Person) will have the right to receive, at any time on or after the
Distribution Date, upon the exercise thereof at the then current Exercise
Price, a number of Depositary Preferred Shares having a market price (as
defined in the Rights Agreement) of two times the Exercise Price.

         With certain exceptions, no adjustment in the Exercise Price will be
required until cumulative adjustments require an adjustment of at least 1% of
the Exercise Price.  No fractional shares (other than fractions that are
integral multiples of one one- thousandth of a share of Series A Preferred
Stock) will be issued, and in lieu thereof, a payment in cash will be made.

         At any time before the earlier of (i) 10 calendar days (subject to
extension by the Board of Directors) following the Stock Acquisition Date,
which is defined to mean the date of the first public announcement by the
Company or an Acquiring Person representing that an Acquiring Person has become
such or (ii) the Expiration Date, the Company may redeem the outstanding Rights
in whole, but not in part, at a price of $.001 per Right (the "Redemption
Price").  Immediately upon the election of the Board of Directors to redeem the
Rights, the holder's right to exercise the Rights will terminate, and such
holder will only be entitled to receive the Redemption Price.

         Until a Right is exercised, the holder thereof, as such, will have no
rights as a stockholder of the Company, including, without limitation, the
right to vote or to receive dividends.





                                      -5-
<PAGE>   6
         Before the Distribution Date, any provision of the Rights Agreement
may, at the direction of the Board of Directors, be supplemented or amended
without the approval of the holders of the Rights.  After the Distribution
Date, the Board of Directors may direct the supplementation or amendment of the
Rights Agreement, without the approval of the holders of the Rights
Certificates (i) to cure any ambiguity or to correct or to supplement any
provision of the Rights Agreement which may be defective or inconsistent with
any other provision therein; (ii) to shorten or lengthen any time period
prescribed in the Rights Agreement; or (iii) to amend or to supplement any
provision of the Rights Agreement in any manner which the Company may deem
necessary or desirable and which will not adversely affect the interests of the
holders of the Rights Certificates (other than an Acquiring  Person, its
affiliates, or associates, each as defined in the Rights Agreement).

         The Rights have certain anti-takeover effects.  The Rights will cause
substantial dilution to any person or group which attempts, without the
approval or consent of the Board of Directors, to acquire the Company (except
pursuant to an offer conditioned on the acquisition of a substantial number of
Rights).  The Rights should not interfere with any merger or other business
combination transaction approved by the Board of Directors since the Board of
Directors may, at its option, at any time before the close of business on the
earlier of (i) the tenth day following the Distribution Date or (ii) the
Expiration Date, redeem all, but not less than all, the then outstanding Rights
at $.001 per Right.

SERIES A JUNIOR PARTICIPATING PREFERRED STOCK

         GENERAL.  Shares of the Series A Preferred Stock may be purchased
pursuant to the terms and conditions of the Rights Agreement.  The Series A
Preferred Stock ranks junior to all other series of the Company's preferred
stock as to the payment of dividends and distribution of assets upon
liquidation, unless otherwise specifically provided in connection with the
designation of a subsequent series of preferred stock.

         DIVIDENDS.  Holders of shares of the Series A Preferred Stock are
entitled to receive, when, as and if declared by the Board of Directors,
dividends out of legally available funds; provided, that no dividend will be
declared and paid with respect to the Common Stock (other than in shares of
Common Stock) unless a dividend is simultaneously declared and paid with
respect to the Series A Preferred Stock in an amount equal to 1,000 times
(subject to adjustment for any stock dividend, stock split or combination with
respect to the Common Stock) the amount of the dividend declared as paid with
respect to the Common Stock.

         LIQUIDATION RIGHTS.  In the event of any liquidation, dissolution, or
winding up of the Company, the holders of shares of the Series A Preferred
Stock are entitled to receive, out of assets of the Company available for
distribution to stockholders and before any distribution is made to holders of
shares of the Company's capital stock ranking junior thereto, liquidating
distributions in the amount of $10 per share, plus an amount equal to any
declared but unpaid dividends thereon, to the date of such distribution;
provided, that the holders of shares of the Series A Preferred Stock will be
entitled to receive an aggregate amount per share equal to 1,000 times (subject
to adjustment for any stock dividend, stock split or combination with respect
to the Common Stock) the aggregate amount distributed per share to holders of
shares of the Common Stock.

         REDEMPTION; CONSOLIDATION OR MERGER.  The shares of Series A Preferred
Stock are not redeemable.  If the Company enters into any consolidation,
merger, combination, or other transaction in which the shares of Common Stock
are exchanged for or changed into other stock or securities, cash, or other
property, the shares of Series A Preferred Stock will be similarly exchanged or
changed in an amount per share (subject to adjustment for any stock dividend,
stock split or combination with respect to the Common Stock) equal to 1,000
times the aggregate amount of stock, securities, cash, or other property, as
the case may be, into which or for which each share of Common Stock is
exchanged or changed.

         VOTING RIGHTS.  Each share of Series A Preferred Stock shall entitle
the holder thereof to 1,000 votes on all matters submitted to a vote of the
stockholders of the Company. This number is subject to adjustment in the event
of any stock dividend, stock split or combination with respect to the Common
Stock.  Except as otherwise provided in the Certificate of Designation of the
Series A Preferred Stock or by applicable law, the holders of shares of Series
A Preferred Stock and the holders of shares of Common Stock shall vote together
as one class on all





                                      -6-
<PAGE>   7
matters submitted to a vote of the stockholders of the Company.  Except as
otherwise provided in the Certificate of Designation of the Series A Preferred
Stock, the holders of Series A Preferred Stock have no special voting rights
and their consent is not required (except to the extent they are entitled to
vote with the holders of shares of Common Stock) for taking any corporate
action.  Cumulative voting by the holders of shares of Series A Preferred Stock
is not permitted.

ITEM 5.  INTERESTS OF NAMED EXPERTS AND COUNSEL

         Not Applicable.

ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

         Article 2.02 of the Texas Business Corporation Act (the "TBCA")
provides that a Texas corporation shall have the power to indemnify directors,
officers, employees and agents and to purchase and maintain liability insurance
for those persons.  Article 2.02-1 of the TBCA empowers the Registrant to
indemnify any director or officer for expenses, including attorneys fees,
judgements, fines and amounts paid in settlement actually and reasonably
incurred in the defense of any action, suit or proceeding in which such
director or officer is a party by reason of his position.

         Pursuant to Article 2.02-1 of the TBCA, Article IV of the Registrant's
Bylaws contains the following provisions regarding indemnification:

                 Each Director or former Director (for purposes of this
         article, "Director") and each officer or former officer (for purposes
         of this article, "Officer") of this corporation and each person who is
         or who may have served at its request as a director or officer of
         another corporation in which it owned shares of stock or of which it
         is a creditor, or as a partner, venturer, proprietor, trustee,
         employee, agent or similar functionary of another partnership, joint
         venture, sole proprietorship, trust, employee benefit plan, or other
         enterprise, shall be indemnified by the corporation against all
         liabilities imposed upon him and actual expenses reasonably incurred
         by him in connection with any claim made against him or any action,
         suit, or proceeding in which he is or is threatened to be made a named
         defendant or respondent by reason of his being or having been such
         Director or Officer.  In no event, however, shall such Director or
         Officer be entitled to indemnification in any action, suit, or
         proceeding in which such Director shall have been found not to have
         acted in good faith and in the reasonable belief that his conduct as
         such Director was in the corporation's best interests; and, in the
         case of an Officer of the corporation, that such Officer did not act
         in good faith in the reasonable belief that his conduct was at least
         not opposed to the corporation's best interests; and in the case of
         any criminal proceeding, such Director or Officer had no reasonable
         cause to believe his conduct was unlawful.   Moreover, no Director
         shall be indemnified for any obligations arising from any action,
         suit, or proceeding in which (i) such Director is found liable on the
         basis that personal profit was improperly received by him, whether or
         not the action resulted from an action taken in his official capacity,
         or (ii) such director is found liable to the corporation.

                 The corporation shall indemnify such Director or Officer to
         the greatest extent permitted by law for reasonable expenses incurred
         in connection with any action, suit, or proceeding in which such
         Director or Officer has been wholly successful in the defense of the
         proceeding, on the merits or otherwise, except that if such action,
         suit, or proceeding was brought by or on behalf of the corporation,
         indemnification shall be limited to reasonable expenses actually
         incurred by such Director or Officer with respect to such proceeding;
         provided, however, that such indemnity shall be conditioned upon the
         prior determination by a majority of the Board of Directors or a
         committee thereof who are not named defendants or respondents in such
         action, suit, or proceeding, or special legal counsel appointed
         thereby, or, solely in the event the Board of Directors is not able to
         act and unable to select special legal counsel, by vote of those
         shareholders who are not also Directors named as defendant or
         respondent in such action, suit, or proceeding,





                                      -7-

         that such Director or Officer has acted in good faith and in the
         reasonable belief as to the best interests of the corporation
         described above.

                 If any pending, threatened, or completed proceeding is
         settled, amounts paid as indemnification of the settlement shall not
         exceed costs, fees and expenses which would have been reasonably
         incurred if the action, suit, or proceeding had been litigated to a
         conclusion.  The determination by the Board of Directors, or by
         independent counsel, and the payment of amounts by the corporation on
         the basis thereof, shall not prevent a shareholder from challenging
         such indemnification by appropriate legal proceedings.  Neither shall
         a determination by the Board of Directors, a committee thereof, or
         special legal counsel appointed thereby, that indemnification is not
         permissible, prevent a Director or Officer from challenging such
         determination by appropriate legal proceedings.  Reasonable expenses
         of a Director or Officer who was, is, or is threatened to be made a
         named defendant or respondent in any proceeding shall be paid in
         advance before any final disposition upon appropriate written request
         to the corporation.

                 The corporation may purchase and maintain insurance on behalf
         of any person who is or was a Director, Officer, employee, or agent of
         the corporation as a director, officer, partner, venturer, proprietor,
         trustee, employee, agent, or similar functionary of another foreign or
         domestic corporation, partnership, joint venture, sole proprietorship,
         trust, employee benefit plan, or other enterprise, against any
         liability asserted against him in such a capacity or arising out of
         his status as such a person, whether or not the corporation would have
         the power to indemnify him against that liability under this article.

                 The foregoing rights and indemnification shall be construed in
         accordance with the laws of the State of Texas as presently in force
         and as hereafter amended.  In all events, these bylaws shall be deemed
         to grant the Directors and Officers the maximum protection consistent
         with law and shall be deemed amended from time to time to reflect any
         changes in such law.  The foregoing shall not be exclusive of any
         private contractual right of indemnification, nor shall it limit the
         same; provided, however, such contractual agreement shall not be
         inconsistent with the Texas Business Corporation Act as presently in
         force or hereafter enacted.

         The Company's Restated Articles of Incorporation contain provisions
eliminating or limiting the liability of a director for an act or omission in
his capacity as director; however, those provisions do not eliminate or limit
the liability of a director for: (i) a breach of a director's duty of loyalty
to the Company or its shareholders; (ii) an act or omission not in good faith
or that involves intentional misconduct or a knowing violation of the law;
(iii) a transaction from which a director received an improper benefit, whether
or not the benefit resulted from an action taken within the scope of the
director's office; (iv) an act or omission from which the liability of a
director is expressly provided for by statute; or (v) an act related to an
unlawful stock repurchase or payment of a dividend.

         The Company's directors and certain executive officers have entered
into Indemnity Agreements with the Company pursuant to which the Company has
agreed, subject to certain conditions, to indemnify such directors and
executive officers against certain liabilities incurred by such persons arising
out of their activities on behalf of the Company.

         The above discussion of the Company's Restated Articles of
Incorporation and Bylaws, and Texas statutes is not intended to be exhaustive
and is qualified in its entirety by such Articles, Bylaws and statutes.

ITEM 9.          UNDERTAKINGS

         A.      Undertaking to Update

                 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
                          ("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;

                 Provided, however, that paragraphs (A)(1)(i) and (A)(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.

         B.      Undertaking With Respect to Documents Incorporated by Reference

                 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 15(d) of the Exchange Act 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.

         C.      Undertaking With Respect to Indemnification

                 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 Securities Act and will be governed by the
                 final adjudication of such issue.

reference pursuant to this Item 3.

ITEM 4.  DESCRIPTION OF SECURITIES

         The following is a summary description of certain of the Company's
securities, and is not intended, and should not be relied upon, as exhaustive.
The description is subject in all respects to the Company's Restated Articles
of Incorporation, the Certificate of Designation, Preferences, Rights and
Limitations of the Company's Series A preferred stock, par value $10.00 per
share (the "Series A Preferred Stock"), and the Rights Agreement dated as of
March 31, 1990 between the Company and Continental Stock Transfer & Trust
Company, as Rights Agent (the "Rights Agreement").  The information set forth
herein is qualified in its entirety by the foregoing reference.

COMMON STOCK

         The Company is authorized by its Restated Articles of Incorporation to
issue 50,000,000 shares of Common Stock of which 35,150,238 shares were issued
and outstanding as of February 3, 1994.  An additional 2,598,668 shares were
reserved for issuance upon the conversion, exchange or exercise of other
outstanding securities or pursuant to various employee benefit plans of the
Company.  As of such date there were 3,789 holders of record of Common Stock.

         VOTING RIGHTS.  The holders of Common Stock are entitled to one vote
for each share held on all matters submitted to a vote of common stockholders.
The Common Stock does not have cumulative voting rights; accordingly, the
holders of a majority of the shares of Common Stock outstanding may elect all
of the nominees for election to the Company's Board of Directors if they choose
to do so.  In such event, the holders of the remaining shares of Common Stock
would not be able to elect any such nominees.

         DIVIDENDS.  Each share of Common Stock is entitled to participate
equally in dividends, if, as and when declared by the Board of Directors, and
in the distribution of assets in the event of liquidation, subject in all cases
to any prior rights of outstanding shares of the Company's preferred stock.
The shares of Common Stock have no preemptive or conversion rights, redemption
provisions or sinking fund provisions.  The outstanding shares of Common Stock
are duly and validly issued, fully paid and nonassessable.

                                      -2-
3
         LISTING.  The Common Stock is listed for trading on the New York Stock
Exchange.

         TRANSFER AGENT AND REGISTRAR.  Continental Stock Transfer & Trust
Company is the Transfer Agent and Registrar of the Common Stock.

PREFERRED STOCK

         Pursuant to the Company's Restated Articles of Incorporation, the
Company is authorized to issue 5,000,000 shares of preferred stock, and the
Company's Board of Directors by resolution may establish one or more series of
preferred stock having such number of shares, designations, relative voting
rights, dividend rights, liquidation and other rights, preferences and
limitations as may be fixed by the Board of Directors without further
stockholder approval.  The Board of Directors has established the Series A
Preferred Stock with 900,000 authorized shares, none of which were outstanding
as of May 13, 1994.  See "Series A Junior Participating Preferred Stock" below.

PROVISIONS OF THE RESTATED ARTICLES OF INCORPORATION WHICH MAY DELAY OR PREVENT
A CHANGE IN CONTROL

         The provisions of the Company's Restated Articles of Incorporation
summarized in the succeeding paragraphs may delay, defer or prevent a tender
offer or takeover attempt that a stockholder might consider to be in such
stockholder's best interest, including those attempts that might result in a
premium price for the shares held by stockholders.

         The Board of Directors of the Company is divided into three classes
that are elected for staggered three-year terms.  Stockholders may remove a
director at any time, with or without cause, but only by the affirmative vote
of the holders of at least 70% of the outstanding shares of capital stock
entitled to vote for the election of directors; provided, that if the Board of
Directors, by an affirmative vote of at least 80% of the entire Board of
Directors, recommends removal of a director to the shareholders, such removal
may be effected by the affirmative vote of the holders of a majority of the
outstanding shares of capital stock entitled to vote on the election of
directors.

         Pursuant to the Company's Restated Articles of Incorporation, the
Board of Directors by resolution may establish one or more series of Preferred
Stock having such number of shares, designations, relative voting rights,
dividend rights, and liquidation and other rights, preferences and limitations
as may be fixed by the Board of Directors without further stockholder approval.
Such rights, preferences, privileges and limitations as may be established
could have the effect of impeding or discouraging the acquisition of control of
the Company.

         The Company's Restated Articles of Incorporation contain a "fair
price" provision that requires the approval of holders of not less than 66 2/3%
of the outstanding shares of capital stock of the Company entitled to vote in
the election of directors not owned, directly or indirectly, by Control Persons
(as defined below) as a condition for mergers, consolidations and other
business combinations involving the Company and any Control Persons; provided
that the 66 2/3% voting requirement is not applicable if:

         (a)     the business combination is solely between the Company and
another corporation of which 50% or more of the voting stock is owned by the
Company and none of which is owned by a Control Person and each holder of
Common Stock receives the same type of consideration in proportion to his
holdings; or

         (b)     all of the following conditions are satisfied:

                 (i)      the cash or reasonably determined fair market value
         of the property, securities or other consideration to be received per
         share in the business combination by holders of the Common Stock is
         not less than the highest price per share paid by the Control Person
         in acquiring any of its holdings of Common Stock;

                                      -3-

                 (ii)     after becoming a Control Person and before the
         consummation of the business combination;

                          (A)     the Control Person has not acquired any newly
                 issued shares of capital stock, directly or indirectly, from
                 the Company (except upon conversion of convertible securities
                 acquired before becoming a Control Person or as a result of a
                 pro-rata stock dividend or stock split or upon compliance with
                 the provisions of the Company's Restated Articles of
                 Incorporation); and

                          (B)     the Control Person has not received the
                 benefit, directly or indirectly (except proportionately as a
                 shareholder), of any loans, advances, guarantees, pledges or
                 other financial assistance or tax credits provided by the
                 Company or made any major changes in the Company's business or
                 equity capital structure; and

                 (iii)    a proxy statement responsive to the requirements of
         the Exchange Act, regardless of whether the Company is then subject to
         such requirements, is mailed to the public shareholders in the Company
         for the purpose of soliciting shareholder approval of such business
         combination; or

         (c)     the business combination is approved by the affirmative vote
of at least a majority of the directors who held office as directors before the
date on which the Control Person became such.

         Control Persons include any holder of 20% or more of the outstanding
shares of Common Stock and any affiliate of such holder.

         The Company's Restated Articles of Incorporation further provide that
special meetings of stockholders can be called only by the chairman of the
board, the president, the Board of Directors, or by the holders of 50% of the
shares of capital stock of the Company entitled to vote at the proposed special
meeting.

SHAREHOLDER RIGHTS PLAN

         On June 20, 1990, the Board of Directors of the Company declared a
dividend distribution of one preferred stock purchase right ("Right") for each
outstanding share of Common Stock.  Each right entitles the registered holder
to purchase from the Company one Depositary Preferred Share, which represents
equitable ownership of one one-thousandth of a share of Series A Preferred
Stock at a price of $80.00 per Depositary Preferred Share (the "Exercise
Price"), subject to adjustment.

         The Rights attach to all certificates representing outstanding or
later issued shares of Common Stock, and no separate Rights certificates have
been distributed.  Until the earlier to occur of (i) 10 calendar days (subject
to extension by the Board of Directors) following a public announcement that a
person or group of affiliated or associated persons has acquired beneficial
ownership of 20% or more of the outstanding shares of Common Stock (an
"Acquiring Person"); or (ii) 10 business days (subject to extension by the
Board of Directors) following a public announcement of a tender or exchange
offer, which, if consummated, would result in an Acquiring Person beneficially
owning 20% or more of the shares of Common Stock (the earlier to occur of such
dates is referred to hereafter as the "Distribution Date"), or earlier
redemption or expiration of the Rights, (a) the Rights will be evidenced with
respect to any of the Common Stock certificates outstanding as of July 2, 1990
by the certificates representing such shares and shall be transferred with and
only with the Common Stock; (b) new Common Stock certificates will contain a
notation incorporating the Rights Agreement by reference; and (c) the surrender
for transfer of any certificates representing shares of Common Stock
outstanding also will constitute the transfer of the Rights associated with
such shares of Common Stock.  As soon as practicable following the Distribution
Date, separate certificates representing the Rights ("Rights Certificates")
will be mailed to holders of record of Common Stock as of the close of business
on the Distribution Date.  Thereafter, the Rights Certificates alone will
evidence the Rights, and the Rights will be transferable separate and apart
from the Common Stock.

                                      -4-
5
         The Rights are not exercisable until the Distribution Date.  Under
certain circumstances set forth in the Rights Agreement, Rights issued to, or
beneficially owned by, a person who is or becomes an Acquiring Person, its
affiliate, or associate, as defined in the Rights Agreement, will become null,
void, and non-transferable.  The Rights will expire at the close of business on
March 31, 2000, unless earlier redeemed by the Board of Directors as described
below.

         The aggregate number of shares of Series A Preferred Stock issuable
upon the exercise of the Rights will be deposited, if, as and when issued, with
Continental Stock Transfer & Trust Company, as depositary (the "Depositary")
under the Depositary Agreement between the Company and the Depositary.  The
Depositary will issue, upon written order, Depositary Receipts, each of which
will represent one or more Depositary Preferred Shares.  Each Depositary
Preferred Share will represent the equitable ownership of one one-thousandth of
a share of Series A Preferred Stock, and will entitle the holder to cast one
vote on all matters upon which the holders of Series A Preferred Stock will be
entitled to vote.

         The Exercise Price payable and the number of Depositary Preferred
Shares properly issuable upon the exercise of the Rights are subject to
adjustment from time to time to prevent dilution (i) in the event of a dividend
payable in, or subdivision or combination of, the Common Stock; (ii) upon the
grant to holders of the Common Stock of rights, options, or warrants entitling
the holder to subscribe for or purchase Common Stock, or securities convertible
into Common Stock, at an exercise price per share of Common Stock less than the
then current market price per share of Common Stock; or (iii) upon the
distribution of evidences of indebtedness, cash (other than a regular periodic
cash dividend out of the retained earnings of the Company), assets (other than
a dividend payable in Common Stock, but including a dividend payable in stock
other than Common Stock) or convertible securities, subscription rights, or
warrants (other than those referred to in clause (ii) above).

         At any time after a person becomes an Acquiring Person, the Board of
Directors may, at its option, exchange all or part of the then outstanding and
exercisable Rights for shares of Common Stock at an exchange ratio of one share
of Common Stock per Right; provided, that the Board of Directors may not effect
such an exchange after the time that any Acquiring Person together with its
affiliates and associates (each as defined in the Rights Agreement) becomes the
beneficial owner of 50% or more of the then outstanding shares of Common Stock.

         If, after any person has become an Acquiring Person, (i) the Company
is acquired in a merger or other business combination transaction, or its
Common Stock is changed into or exchanged for other securities or assets, or
(ii) more than 50% of the Company's assets or earning power is sold, each Right
will entitle the holder to purchase, upon the exercise thereof at the then
current Exercise Price, a number of shares of common stock of the acquiring
company having a market price (as defined in the Rights Agreement) of two times
the Exercise Price.  If any person or group becomes the beneficial owner of 20%
or more of outstanding shares of Common Stock, then each holder (other than an
Acquiring Person) will have the right to receive, at any time on or after the
Distribution Date, upon the exercise thereof at the then current Exercise
Price, a number of Depositary Preferred Shares having a market price (as
defined in the Rights Agreement) of two times the Exercise Price.

         With certain exceptions, no adjustment in the Exercise Price will be
required until cumulative adjustments require an adjustment of at least 1% of
the Exercise Price.  No fractional shares (other than fractions that are
integral multiples of one one- thousandth of a share of Series A Preferred
Stock) will be issued, and in lieu thereof, a payment in cash will be made.

         At any time before the earlier of (i) 10 calendar days (subject to
extension by the Board of Directors) following the Stock Acquisition Date,
which is defined to mean the date of the first public announcement by the
Company or an Acquiring Person representing that an Acquiring Person has become
such or (ii) the Expiration Date, the Company may redeem the outstanding Rights
in whole, but not in part, at a price of $.001 per Right (the "Redemption
Price").  Immediately upon the election of the Board of Directors to redeem the
Rights, the holder's right to exercise the Rights will terminate, and such
holder will only be entitled to receive the Redemption Price.

         Until a Right is exercised, the holder thereof, as such, will have no
rights as a stockholder of the Company, including, without limitation, the
right to vote or to receive dividends.

                                      -5-
6
         Before the Distribution Date, any provision of the Rights Agreement
may, at the direction of the Board of Directors, be supplemented or amended
without the approval of the holders of the Rights.  After the Distribution
Date, the Board of Directors may direct the supplementation or amendment of the
Rights Agreement, without the approval of the holders of the Rights
Certificates (i) to cure any ambiguity or to correct or to supplement any
provision of the Rights Agreement which may be defective or inconsistent with
any other provision therein; (ii) to shorten or lengthen any time period
prescribed in the Rights Agreement; or (iii) to amend or to supplement any
provision of the Rights Agreement in any manner which the Company may deem
necessary or desirable and which will not adversely affect the interests of the
holders of the Rights Certificates (other than an Acquiring  Person, its
affiliates, or associates, each as defined in the Rights Agreement).

         The Rights have certain anti-takeover effects.  The Rights will cause
substantial dilution to any person or group which attempts, without the
approval or consent of the Board of Directors, to acquire the Company (except
pursuant to an offer conditioned on the acquisition of a substantial number of
Rights).  The Rights should not interfere with any merger or other business
combination transaction approved by the Board of Directors since the Board of
Directors may, at its option, at any time before the close of business on the
earlier of (i) the tenth day following the Distribution Date or (ii) the
Expiration Date, redeem all, but not less than all, the then outstanding Rights
at $.001 per Right.

SERIES A JUNIOR PARTICIPATING PREFERRED STOCK

         GENERAL.  Shares of the Series A Preferred Stock may be purchased
pursuant to the terms and conditions of the Rights Agreement.  The Series A
Preferred Stock ranks junior to all other series of the Company's preferred
stock as to the payment of dividends and distribution of assets upon
liquidation, unless otherwise specifically provided in connection with the
designation of a subsequent series of preferred stock.

         DIVIDENDS.  Holders of shares of the Series A Preferred Stock are
entitled to receive, when, as and if declared by the Board of Directors,
dividends out of legally available funds; provided, that no dividend will be
declared and paid with respect to the Common Stock (other than in shares of
Common Stock) unless a dividend is simultaneously declared and paid with
respect to the Series A Preferred Stock in an amount equal to 1,000 times
(subject to adjustment for any stock dividend, stock split or combination with
respect to the Common Stock) the amount of the dividend declared as paid with
respect to the Common Stock.

         LIQUIDATION RIGHTS.  In the event of any liquidation, dissolution, or
winding up of the Company, the holders of shares of the Series A Preferred
Stock are entitled to receive, out of assets of the Company available for
distribution to stockholders and before any distribution is made to holders of
shares of the Company's capital stock ranking junior thereto, liquidating
distributions in the amount of $10 per share, plus an amount equal to any
declared but unpaid dividends thereon, to the date of such distribution;
provided, that the holders of shares of the Series A Preferred Stock will be
entitled to receive an aggregate amount per share equal to 1,000 times (subject
to adjustment for any stock dividend, stock split or combination with respect
to the Common Stock) the aggregate amount distributed per share to holders of
shares of the Common Stock.

         REDEMPTION; CONSOLIDATION OR MERGER.  The shares of Series A Preferred
Stock are not redeemable.  If the Company enters into any consolidation,
merger, combination, or other transaction in which the shares of Common Stock
are exchanged for or changed into other stock or securities, cash, or other
property, the shares of Series A Preferred Stock will be similarly exchanged or
changed in an amount per share (subject to adjustment for any stock dividend,
stock split or combination with respect to the Common Stock) equal to 1,000
times the aggregate amount of stock, securities, cash, or other property, as
the case may be, into which or for which each share of Common Stock is
exchanged or changed.

         VOTING RIGHTS.  Each share of Series A Preferred Stock shall entitle
the holder thereof to 1,000 votes on all matters submitted to a vote of the
stockholders of the Company. This number is subject to adjustment in the event
of any stock dividend, stock split or combination with respect to the Common
Stock.  Except as otherwise provided in the Certificate of Designation of the
Series A Preferred Stock or by applicable law, the holders of shares of Series
A Preferred Stock and the holders of shares of Common Stock shall vote together
as one class on all

                                      -6-
7
matters submitted to a vote of the stockholders of the Company.  Except as
otherwise provided in the Certificate of Designation of the Series A Preferred
Stock, the holders of Series A Preferred Stock have no special voting rights
and their consent is not required (except to the extent they are entitled to
vote with the holders of shares of Common Stock) for taking any corporate
action.  Cumulative voting by the holders of shares of Series A Preferred Stock
is not permitted.

ITEM 5.  INTERESTS OF NAMED EXPERTS AND COUNSEL

         Not Applicable.

ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

         Article 2.02 of the Texas Business Corporation Act (the "TBCA")
provides that a Texas corporation shall have the power to indemnify directors,
officers, employees and agents and to purchase and maintain liability insurance
for those persons.  Article 2.02-1 of the TBCA empowers the Registrant to
indemnify any director or officer for expenses, including attorneys fees,
judgements, fines and amounts paid in settlement actually and reasonably
incurred in the defense of any action, suit or proceeding in which such
director or officer is a party by reason of his position.

         Pursuant to Article 2.02-1 of the TBCA, Article IV of the Registrant's
Bylaws contains the following provisions regarding indemnification:

                 Each Director or former Director (for purposes of this
         article, "Director") and each officer or former officer (for purposes
         of this article, "Officer") of this corporation and each person who is
         or who may have served at its request as a director or officer of
         another corporation in which it owned shares of stock or of which it
         is a creditor, or as a partner, venturer, proprietor, trustee,
         employee, agent or similar functionary of another partnership, joint
         venture, sole proprietorship, trust, employee benefit plan, or other
         enterprise, shall be indemnified by the corporation against all
         liabilities imposed upon him and actual expenses reasonably incurred
         by him in connection with any claim made against him or any action,
         suit, or proceeding in which he is or is threatened to be made a named
         defendant or respondent by reason of his being or having been such
         Director or Officer.  In no event, however, shall such Director or
         Officer be entitled to indemnification in any action, suit, or
         proceeding in which such Director shall have been found not to have
         acted in good faith and in the reasonable belief that his conduct as
         such Director was in the corporation's best interests; and, in the
         case of an Officer of the corporation, that such Officer did not act
         in good faith in the reasonable belief that his conduct was at least
         not opposed to the corporation's best interests; and in the case of
         any criminal proceeding, such Director or Officer had no reasonable
         cause to believe his conduct was unlawful.   Moreover, no Director
         shall be indemnified for any obligations arising from any action,
         suit, or proceeding in which (i) such Director is found liable on the
         basis that personal profit was improperly received by him, whether or
         not the action resulted from an action taken in his official capacity,
         or (ii) such director is found liable to the corporation.

                 The corporation shall indemnify such Director or Officer to
         the greatest extent permitted by law for reasonable expenses incurred
         in connection with any action, suit, or proceeding in which such
         Director or Officer has been wholly successful in the defense of the
         proceeding, on the merits or otherwise, except that if such action,
         suit, or proceeding was brought by or on behalf of the corporation,
         indemnification shall be limited to reasonable expenses actually
         incurred by such Director or Officer with respect to such proceeding;
         provided, however, that such indemnity shall be conditioned upon the
         prior determination by a majority of the Board of Directors or a
         committee thereof who are not named defendants or respondents in such
         action, suit, or proceeding, or special legal counsel appointed
         thereby, or, solely in the event the Board of Directors is not able to
         act and unable to select special legal counsel, by vote of those
         shareholders who are not also Directors named as defendant or
         respondent in such action, suit, or proceeding,

                                      -7-
8
         that such Director or Officer has acted in good faith and in the
         reasonable belief as to the best interests of the corporation
         described above.

                 If any pending, threatened, or completed proceeding is
         settled, amounts paid as indemnification of the settlement shall not
         exceed costs, fees and expenses which would have been reasonably
         incurred if the action, suit, or proceeding had been litigated to a
         conclusion.  The determination by the Board of Directors, or by
         independent counsel, and the payment of amounts by the corporation on
         the basis thereof, shall not prevent a shareholder from challenging
         such indemnification by appropriate legal proceedings.  Neither shall
         a determination by the Board of Directors, a committee thereof, or
         special legal counsel appointed thereby, that indemnification is not
         permissible, prevent a Director or Officer from challenging such
         determination by appropriate legal proceedings.  Reasonable expenses
         of a Director or Officer who was, is, or is threatened to be made a
         named defendant or respondent in any proceeding shall be paid in
         advance before any final disposition upon appropriate written request
         to the corporation.

                 The corporation may purchase and maintain insurance on behalf
         of any person who is or was a Director, Officer, employee, or agent of
         the corporation as a director, officer, partner, venturer, proprietor,
         trustee, employee, agent, or similar functionary of another foreign or
         domestic corporation, partnership, joint venture, sole proprietorship,
         trust, employee benefit plan, or other enterprise, against any
         liability asserted against him in such a capacity or arising out of
         his status as such a person, whether or not the corporation would have
         the power to indemnify him against that liability under this article.

                 The foregoing rights and indemnification shall be construed in
         accordance with the laws of the State of Texas as presently in force
         and as hereafter amended.  In all events, these bylaws shall be deemed
         to grant the Directors and Officers the maximum protection consistent
         with law and shall be deemed amended from time to time to reflect any
         changes in such law.  The foregoing shall not be exclusive of any
         private contractual right of indemnification, nor shall it limit the
         same; provided, however, such contractual agreement shall not be
         inconsistent with the Texas Business Corporation Act as presently in
         force or hereafter enacted.

         The Company's Restated Articles of Incorporation contain provisions
eliminating or limiting the liability of a director for an act or omission in
his capacity as director; however, those provisions do not eliminate or limit
the liability of a director for: (i) a breach of a director's duty of loyalty
to the Company or its shareholders; (ii) an act or omission not in good faith
or that involves intentional misconduct or a knowing violation of the law;
(iii) a transaction from which a director received an improper benefit, whether
or not the benefit resulted from an action taken within the scope of the
director's office; (iv) an act or omission from which the liability of a
director is expressly provided for by statute; or (v) an act related to an
unlawful stock repurchase or payment of a dividend.

         The Company's directors and certain executive officers have entered
into Indemnity Agreements with the Company pursuant to which the Company has
agreed, subject to certain conditions, to indemnify such directors and
executive officers against certain liabilities incurred by such persons arising
out of their activities on behalf of the Company.

         The above discussion of the Company's Restated Articles of
Incorporation and Bylaws, and Texas statutes is not intended to be exhaustive
and is qualified in its entirety by such Articles, Bylaws and statutes.

ITEM 9.          UNDERTAKINGS

         A.      Undertaking to Update

                 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
                          ("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;

                 Provided, however, that paragraphs (A)(1)(i) and (A)(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.

         B.      Undertaking With Respect to Documents Incorporated by Reference

                 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 15(d) of the Exchange Act 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.

         C.      Undertaking With Respect to Indemnification

                 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 Securities Act and will be governed by the
                 final adjudication of such issue.
