and if redeemed at any time thereafter as $50.00 per share, plus, in each case,
an amount equal to accumulations of unpaid dividends thereon to the redemption
date.

                  (2) Redemption in Connection with a Fundamental Transaction.
If any time prior to August 15, 2002 the holders of the outstanding shares of
$4.125 Preferred Stock fail to approve a Fundamental Transaction as required by
paragraph (c)(2)(B) above, such shares may be redeemed in full at the option of
the Corporation for cash at $50.00 per share, plus an amount equal to
accumulations of unpaid dividends thereon to the redemption date. The
Corporation may not exercise the redemption right provided in this paragraph
(f)(2) unless the Corporation proceeds with the Fundamental Transaction which
the holders of $4.125 Preferred Stock failed to approve.

                  (3) Notice Procedures. Not less than 30 nor more than 60 days
prior to the date fixed for any redemption of shares of the $4.125 Preferred
Stock pursuant to this paragraph (f), a written notice specifying the time and
place of such redemption, the redemption price and the number of shares to be
redeemed shall be given by first class mail, postage prepaid, to the holders of
record of the shares of the $4.125 Preferred Stock to be redeemed at their
respective addresses as the same shall appear on the books of the Corporation,
calling upon each such holder of record to surrender to the Corporation on the
redemption date at the place designated in such notice the holder's certificate
or certificates representing the number of shares specified in such notice of
redemption. Neither a failure to mail such notice, nor any defect therein or in
the mailing thereof, to any particular holder shall affect the sufficiency of
the notice or the validity of the proceedings for redemption with respect to the
other holders. Any notice that is mailed in the manner herein provided shall be
conclusively presumed to have been duly given whether or not the holder receives
the notice. On or after the redemption date each holder of shares of the $4.125
Preferred Stock to be redeemed shall present and surrender the certificate or
certificates for such shares to the Corporation at the place designated in such
notice, and thereupon the redemption price of such shares shall be paid to or to
the order of the Person whose name appears on such certificate or certificates
as the owner thereof and each surrendered certificate shall be cancelled. In
case fewer than all the shares represented by any such certificate are redeemed,
a new certificate shall be issued representing the unredeemed shares.


                                      II-8


                  (4) Cessation of Rights as Stockholder. If a notice of
redemption has been given pursuant to subparagraph (f)(3) above and if, on or
before the date fixed for redemption, the funds necessary for such redemption
shall have been deposited by the Corporation, in trust for the pro rata benefit
of the holders of the shares so called for redemption (so as to be and continue
to be available therefor) with a bank or trust company doing business in
Philadelphia, Pennsylvania and having capital, surplus and undivided profits
aggregating at least $100,000,000, then, notwithstanding that any certificates
for such shares have not been surrendered for cancellation, on the redemption
date dividends shall cease to accrue on the shares of the $4.125 Preferred Stock
to be redeemed, and at the close of business on the redemption date the holders
of such shares shall cease to be stockholders with respect to such shares and
shall have no interest in or claims against the Corporation by virtue thereof
and shall have no voting or other rights with respect to such shares (except the
right to receive the moneys payable upon such redemption, without interest
thereon, upon surrender, and endorsement if required by the Corporation, of
their certificates), and the shares evidenced thereby shall not be deemed to be
outstanding shares for the purpose of voting or determining the total number of
shares entitled to vote on any matter. Any moneys so deposited by the
Corporation and unclaimed at the end of two years from the redemption date may
revert to the general funds of the Corporation, and any funds held by any paying
agent may be paid to the Corporation upon request of the Corporation, after
which reversion or payment the holders of such shares so called for redemption
shall look only to the general funds of the Corporation for the payment of the
redemption price. Any interest accrued on funds so deposited shall be paid to
the Corporation from time to time.

                  (5) Partial Redemption Procedures. If fewer than all of the
outstanding shares of the $4.125 Preferred Stock shall be called for redemption
pursuant to this prargraph (f)(1) above, the shares to be redeemed shall be
selected pro rata, as nearly as practicable, or by lot or by such other manner
as may be prescribed by resolution of the Board of Directors of the Corporation
and shall be consistent with the applicable rules of the National Association of
Securities Dealers.

            (g) Sinking Fund. Except as otherwise provided in this paragraph
(g), the shares of the $4.125 Preferred Stock are not subject to mandatory
redemption requirements.

                  (1) Mandatory Redemption. So long as any share of $4.125
Preferred Stock remains outstanding, on August 15 of each year from 2002 to
2011, inclusive, the Corporation shall redeem 72,000 shares, and on August 15,
2012 shall redeem all shares then outstanding, at a price of $50.00 per share
plus accrued and unpaid cumulative dividends to date of redemption.

                  On or before each such August 15, the Corporation shall,
deposit all finds necessary for the redemption of shares of $4.125 Preferred
Stocks above provided, in trust for the account of the holders of the shares to
be redeemed, so as to be and continue to be available therefor, with a bank or
trust company doing business in Philadelphia, Pennsylvania, and having capital,
surplus and undivided profits aggregating at least $10,000,000. The particular
shares of $4.125 Preferred Stock so to be redeemed


                                      II-9


shall be determined, notice of such redemption shall be given and the deposit of
funds shall be made by the Corporation in the manner and with the effect
provided in paragraph (g) hereof.

                  If the Corporation fails to comply with its sinking fund
obligation as heretofore provided, it shall make good any such deficiency at the
earliest possible time thereafter. The obligation to redeem shares of $4.125
Preferred Stock for the sinking fund as aforesaid shall be cumulative if and to
the extent not satisfied in any year, whether or not there shall be funds
legally available therefor, but without interest on the amount of any
deficiencies.

                  Against the number of shares required to be redeemed in any
year by the provisions of this paragraph (g), the Corporation may credit shares
of $4.125 Preferred Stock which it has purchased or redeemed at any time during
or prior to such year otherwise than through the operation of the sinking fund
provided that any shares so credited shall not theretofore have been used for
the purpose of such credit.

                  (2) Notice Procedures. Not less than 30 nor more than 60 days
prior to any redemption date, a written notice specifying the sinking fund
deposit made or to be made, the redemption date, the time and place of such
redemption, the redemption price and the number of shares to be redeemed shall
be given by first class mail, postage prepaid, to the holders of record of
shares of the $4.125 Preferred Stock at their respective addresses as the same
shall appear on the books of the Corporation, calling upon each such holder of
record to surrender to the Corporation on the redemption date at the place
designated in such notice the holder's certificate or certificates representing
the number of shares specified in such notice of redemption. Neither a failure
to mail such notice, nor any defect therein or in the mailing thereof to any
particular holder shall affect the sufficiency of the notice or the validity of
the proceedings for redemption with respect to the other holders. Any notice
that is mailed in the manner herein provided shall be conclusively presumed to
have been duly given whether or not the holder receives the notice. On or after
the redemption date each holder of shares of the $4.125 Preferred Stock to be
redeemed shall present and surrender the certificate or certificates for such
shares to the Corporation at the place designated in such notice, and thereupon
the redemption price of such shares shall be paid to or to the order of the
Person whose name appears on such certificate or certificates as the owner
thereof and each surrendered certificate shall be cancelled. In case fewer than
all the shares represented by any such certificate are redeemed, a new
certificate shall be issued representing the unredeemed shares.

                  (3) Cessation of Rights as Stockholder. If a notice of
redemption has been given pursuant to subparagraph (g)(2) above and if, on or
before the date fixed for redemption, the funds necessary for such redemption
shall have been deposited pursuant to subparagraph (g)(1) above, then
notwithstanding that any certificates for such shares have not been surrendered
for cancellation, on the redemption date dividends shall cease to accrue on the
shares of the $4.125 Preferred Stock to be redeemed, and at the close of
business on the redemption date the holders of such shares shall cease to be
stockholders with respect to such shares and shall have no interest in or


                                     II-10


claims against the Corporation by virtue thereof and shall have no voting or
other rights with respect to such shares (except the right to receive the moneys
payable upon such redemption, without interest thereon, upon surrender, and
endorsement if required by the Corporation, of their certificates), and the
shares evidenced thereby shall not be deemed to be outstanding shares for the
purpose of voting or determining the total number of shares entitled to vote on
any matter. Any moneys so deposited by the Corporation and unclaimed at the end
of two years from the redemption date may revert to the general funds of the
Corporation, and any funds held by any paying agent may be paid to the
Corporation upon request of the Corporation, after which reversion or payment
the holders of such shares so called for redemption shall look only to the
general funds of the Corporation for the payment of the redemption price. Any
interest accrued on funds so deposited shall be paid to the Corporation from
time to time.

                  (4) Partial Redemption Procedures. Any shares to be redeemed
pursuant to this paragraph (g) shall be selected pro rata, as nearly as
practicable, or by lot as may be prescribed by resolution of the Board of
Directors of the Corporation and shall be consistent with the applicable rules
of the National Association of Securities Dealers.

                  (5) Default. Unless and until (x) all accumulations of unpaid
dividends on shares of the $4.125 Preferred Stock and any Parity Dividend Shares
at the time outstanding have been paid in full or declared in full and sums set
apart for the payment thereof and (y) the Corporation has fully complied with
all scheduled redemption obligations, sinking fund obligations and all other
redemption obligations relating to the shares of $4.125 Preferred Stock, any
Parity Dividend Shares and any Parity Liquidation Shares at the time
outstanding, the payment of dividends on, and redemptions and purchases of,
shares of the Corporation's capital stock shall be subject to the restrictions
contained in paragraph (h) below.

            (h) Dividend and Redemption Default Provisions. Unless and until (x)
all accumulations of unpaid dividends on shares of the $4.125 Preferred Stock
and any Parity Dividend Shares at the time outstanding have been paid in full or
declared in full and sums set apart for the payment thereof and (y) the
Corporation has fully complied with all scheduled redemption obligations,
sinking fund obligations and all other redemption obligations relating to the
shares of $4.125 Preferred Stock, any Parity Dividend Shares and any Parity
Liquidation Shares at the time outstanding:


                  (1) No dividends may be declared or paid or set aside for
payment and no other distribution may be made in respect of any Common Shares,
Junior Dividend Shares or (except as provided above in subparagraph (d) (4))
Parity Dividend Shares, except dividends or other distributions in Common Shares
or Junior Dividend Shares.

                  (2) No Common Shares, Junior Dividend Shares or Junior
Liquidation Shares may be redeemed, purchased or otherwise acquired for any
Consideration (or any payment made to or available for a sinking fund for the
redemption of any such shares) by the Corporation or any entity controlled by
the Corporation


                                     II-11


(except (i) by conversion into or exchange for stock of the Corporation ranking
junior to shares of the $4.125 Preferred Stock as to dividend and liquidation
rights, (ii) in repurchases of Common Shares, Junior Dividend Shares or Junior
Liquidation Shares from employees or directors of or consultants to the
Corporation pursuant to contractual arrangements entered into at the time such
shares were issued giving the Corporation the right to repurchase such shares
upon the occurrence of certain contingencies and (iii) by acquisition of Common
Shares, Junior Dividend Shares or Junior Liquidation Shares issued in connection
with an acquisition pursuant to an escrow, pledge or similar arrangement under
which the Corporation becomes entitled to receive such shares).

                  (3) No shares of the $4.125 Preferred Stock or any Parity
Dividend Shares or Parity Liquidation Shares may be redeemed unless all
outstanding shares of the $4.125 Preferred Stock are redeemed.

                  (4) No shares of the $4.125 Preferred Stock or any Parity
Dividend Shares or Parity Liquidation Shares may be purchased or otherwise
acquired by the Corporation for value except in accordance with a purchase or
exchange offer made simultaneously by the Corporation to all holders of record
of shares of the $4.125 Preferred Stock, Parity Dividend Shares and Parity
Liquidation Shares which, considering the annual dividend rates and the other
relative rights and preferences of such shares, in the opinion of the Board of
Directors (whose determination shall be conclusive), will result in fair and
equitable treatment among all such shares.

            (i) Status of Redeemed Shares. All shares of the $4.125 Preferred
Stock which are at any time redeemed pursuant to paragraph (f) or (g) above and
all shares of the $4.125 Preferred Stock which are otherwise reacquired by the
Corporation and subsequently cancelled by the Board of Directors shall have the
status of authorized but unissued shares of Preferred Stock, without designation
as to series, subject to reissuance by the Board of Directors as shares of any
one or more other series.

      4.3 Series A Preferred Stock. The Corporation is authorized to issue a
series of Preferred Stock, which shall consist of 100,000 shares and is
designated as "Series A Junior Participating Preferred Shares" (the "SERIES A
PREFERRED SHARE"). The powers, preferences, rights, restrictions and other
matters relating to the Series A Preferred Shares are as follows:

            (a) Dividends and Distributions.

                  (1) The rate of dividends payable per share of Series A
Preferred Shares on the first day of January, April, July and October in each
year or such other quarterly payment date as shall be specified by the Board of
Directors (each such data being referred to herein as a "QUARTERLY DIVIDEND
PAYMENT DATE"), commencing on the first Quarterly Dividend Payment Date after
the first issuance of a share or fraction of a share of the Series A Preferred
Shares, shall be (rounded to the nearest cent) equal to the greater of (A)
$10.00 or (B) subject to the provision for adjustment hereinafter set forth,
1,000 times the aggregate per share amount of all cash dividends and 1,000 times
the aggregate per share amount (payable in cash, based upon the fair


                                     II-12


market value at the time the non-cash dividend or other distribution is declared
or paid as determined in good faith by the Board of Directors) of all non-cash
dividends or other distributions other than a dividend payable in shares of
Common Stock or a subdivision of the outstanding shares of Common Stock (by
reclassification or otherwise), declared on the Common Stock, $.001 per value
per share, of the Corporation since the immediately preceding Quarterly Dividend
Payment Date, or, with respect to the first Quarterly Dividend Payment Date,
since the first issuance of any share or fraction of a share of the Series A
Preferred Shares. Dividends on the Series A Preferred Shares shall be paid out
of funds legally available for such purpose. In the event the Corporation shall
at any time after April 14,1995 (the "RIGHTS DECLARATION DATE") (A) declare any
dividend on Common Stock payable in shares of Common Stock, (B) subdivide the
outstanding shares of Common Stock, or (C) combine the outstanding shares of
Common Stock into a smaller number of shares, then in each such case the amounts
to which holders of Series A Preferred Shares were entitled immediately prior to
such event under clause (D) of the preceding sentence shall be adjusted by
multiplying each such amount by a fraction the numerator of which is the number
of shares of Common Stock outstanding immediately after such event and the
denominator of which is the number of shares of Common Stock that were
outstanding immediately prior to such event.

                  (2) Dividends shall begin to accrue and be cumulative on
outstanding Series A Preferred Shares from the Quarterly Dividend Payment Date
next preceding the date of issue of such Series A Preferred Shares, unless the
date of issue of such shares is prior to the record date for the first Quarterly
Dividend Payment Date in which case dividends on such shares shall begin to
accrue from the date of issue of such shares, or unless the date of issue is a
Quarterly Dividend Payment Date or is a date after the record date for the
determination of holders of Series A Preferred Shares entitled to receive a
quarterly dividend and before such Quarterly Dividend Payment Date, in either of
which events such dividends shall begin to accrue and be cumulative from such
Quarterly Dividend Payment Date. Accrued but unpaid dividends shall nor bear
interest. Dividends paid on the Series A Preferred Shares in an amount less than
the total amount of such dividends at the time accrued and payable on such
shares shall be allocated pro rata on a share-by-share basis among all such
shares at the time outstanding.

            (b) Voting Rights. In addition to any other voting rights required
by law, the holders of Series A Preferred Shares shall have the following voting
rights:

                  (1) Subject to the provision for adjustment hereinafter set
forth, each Series A Preferred Share shall entitle the holder thereof to 1,000
votes on all matters submitted to a vote of the stockholders of the Corporation.
In the event the Corporation shall at any time after the Rights Declaration Date
(A) declare any dividend on Common Stock payable in shares of Common Stock, (B)
subdivide the outstanding shares of Common Stock, or (C) combine the outstanding
shares of Common Stock into a smaller number of shares, then in each such case
the number of votes per share to which holders of Series A Preferred Shares were
entitled immediately prior to such event shall be adjusted by multiplying such
number by a fraction the numerator of which is the number of shares of Common
Stock outstanding immediately after such event and the


                                     II-13


denominator of which is the number of shares of Common Stock that were
outstanding immediately prior to such event.

                  (2) In the event that dividends upon the Series A Preferred
Shares shall be in arrears to an amount equal to six full quarterly dividends
thereon, the holders of such Series A Preferred Shares shall become entitled to
the extent hereinafter provided to vote noncumulatively at all elections of
directors of the Corporation, and to receive notice of all stockholders'
meetings to be held for such purpose. At such meetings, to the extent that
directors are being elected, the holders of such Series A Preferred Shares
voting as a class shall be entitled solely to elect two members of the Board of
Directors of the Corporation; and all other directors of the Corporation shall
be elected by the other stockholders of the Corporation entitled to vote in the
election of directors. Such voting rights of the holders of such Series A
Preferred Shares shall continue until all accumulated and unpaid dividends
thereon shall have been paid or funds sufficient therefor set side, whereupon
all such voting rights of the holders of shares of such series shall cease,
subject to being again revived from time to time upon the reoccurrence of the
conditions above described as giving rise thereto.

                  At any time when such right to elect directors separately as a
class shall have so vested, the Corporation may, and upon the written request of
the holders of record of not less than 15% of the then outstanding total number
of shares of all the Series A Preferred Shares having the right to elect
directors in such circumstances shall, call a special meeting of holders of such
Series A Preferred Shares for the election of directors. In the case of such a
written request, such special meeting shall be held within ninety (90) days
after the delivery of such request, and, in either case, at the place and upon
the notice provided by law and in the By-laws of the Corporation; provided, that
the Corporation shall not be required to call such a special meeting if such
request is received less than one hundred twenty (120) days before the date
fixed for the next ensuing annual or special meeting of stockholders of the
Corporation. Upon the mailing of the notice of such special meeting to the
holders of such Series A Preferred Shares, or, if no such meeting be held, then
upon the mailing of the notice of the next annual or special meeting of
stockholders for the election of directors, the number of directors of the
Corporation shall, ipso facto, be increased to the extent, but only to the
extent, necessary to provide sufficient vacancies to enable the holders of such
Series A Preferred Shares to elect the two directors hereinabove provided for,
and all such vacancies shall be filled only by vote of the holders of such
Series A Preferred Shares as hereinabove provided. Whenever the number of
directors of the Corporation shall have been increased, the number as so
increased may thereafter be further increased or decreased in such manner as may
be permitted by the By-laws and without the vote of the holders of Series A
Preferred Shares, provided that no such action shall impair the right of the
holders of Series A Preferred Shares to elect and to be represented by two
directors as herein provided.

                  So long as the holders of Series A Preferred Shares are
entitled hereunder to voting rights, any vacancy in the Board of Directors
caused by the death or resignation of any director elected by the holders of
Series A Preferred Shares, shall, until the next meeting of stockholders for the
election of directors, in each case be filled


                                     II-14


by the remaining director elected by the holders of Series A Preferred Shares
having the right to elect directors in such circumstances.

                  Upon termination of the voting rights of the holders of any
series of Series A Preferred Shares the terms of office of all persons who shall
have been elected directors of the Corporation by vote of the holders of Series
A Preferred Shares or by a director elected by such holders shall forthwith
terminate.

                  (3) Except as otherwise provided herein, in the Certificate of
Incorporation of the Corporation or by law, the holders of Series A Preferred
Shares and the holders of Common Stock (and the holders of shares of any other
series or class entitled to vote thereon) shall vote together as one class on
all matters submitted to a vote of stockholders of the Corporation.

            (c) Reacquired Shares. Any Series A Preferred Shares purchased or
otherwise acquired by the Corporation in any manner whatsoever shall be retired
and canceled promptly after the acquisition thereof. All such shares shall upon
their cancellation become authorized but unissued Series Preferred Stock and may
be reissued as part of a new series of Series Preferred Stock to be created by
resolution or resolutions of the Board of Directors.

            (d) Liquidation, Dissolution or Winding Up. In the event of any
voluntary or involuntary liquidation, dissolution or winding up of the
Corporation, the holders of Series A Preferred Shares shall be entitled to
receive the greater of (1) $100.00 per share, plus accrued dividends to the date
of distribution, whether or not earned or declared, or (2) an amount per share,
subject to the provision for adjustment hereinafter set forth, equal to 1,000
times the aggregate amount to be distributed per share to holders of Common
Stock. In the event the Corporation shall at any time after the Rights
Declaration Date (A) declare any dividend on Common Stock payable in shares of
Common Stock, (B) subdivide the outstanding shares of Common Stock, or (C)
combine the outstanding shares of Common Stock into a smaller number of shares,
then in each such case the amount to which holders of Series A Preferred Shares
were entitled immediately prior to such event pursuant to clause (2) of the
preceding sentence shall be adjusted by multiplying such amount by a fraction
the numerator of which is the number of shares of Common Stock outstanding
immediately alter such event and the denominator of which is the number of
shares of Common Stock that were outstanding immediately prior to such event.

            (e) Consolidation, Merger, etc. In case the Corporation shall enter
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 and/or any other property, then in any such case the Series A
Preferred Shares shall at the same time be similarly exchanged or changed in an
amount per share (subject to the provision for adjustment hereinafter set forth)
equal to 1,000 times the aggregate amount of stock, securities, cash and/or any
other property (payable in kind), as the case may be, into which or for which
each share of Common Stock is changed or exchanged. In the event the Corporation
shall at any time after the Rights Declaration Date (1) declare any dividend on
Common Stock payable in shares of Common Stock, (2) subdivide the


                                     II-15


outstanding shares of Common Stock, or (3) combine the outstanding shares of
Common Stock into a smaller number of shares, then in each such case the amount
set forth in the Preferred Shares shall be adjusted by multiplying such amount
by a fraction the numerator of which is the number of shares of Common Stock
outstanding immediately after such event and the denominator of which is the
number of shares of Common Stock that were outstanding immediately prior to such
event.

            (f) No Redemption. The Series A Preferred Shares shall not be
redeemable.

            (g) Ranking. The Series A Preferred Shares shall rank junior to all
other series of the Corporation's Series Preferred Stock as to the payment of
dividends and the distribution of assets, unless the terms of any such series
shall provide otherwise.

            (h) Fractional Shares. Series A Preferred Shares may be issued in
fractions of a share which shall entitle the holder, in proportion to such
holder's fractional shares, to exercise voting rights, receive dividends,
participate in distributions and so have the benefit of all other rights of
holders of Series A Preferred Shares.

FIFTH: Board of Directors.

      5.1 Number; Classification. The Board of Directors of the Corporation
shall consist of such number of directors, which number shall not be less than 9
or more than 14, as shall be fixed from time so time by resolution of the Board.
The Board of Directors shall be divided into three classes, which shall be as
nearly equal in number as possible. Directors of each class shall serve for a
term of three years and until their successors shall have been elected and
qualified. The three initial classes of directors shall be comprised as follows:

            (a) Class I shall be comprised of directors who shall serve until
the annual meeting of stockholders in 1993 and until their successors shall have

been elected and qualified.

      5.2 Qualifications. No person shall be appointed or elected a director of
the Corporation unless;

            (a) such person is elected to fill a vacancy in the Board of
Directors (including any vacancy resulting from any increase in the authorized
number of directors) by a vote of the majority of the Board of Directors then in
office, and any


                                     II-16


director so elected shall hold office until the next election of the class for
which such director shall have been elected and until a successor shall have
been elected and qualified; or

            (b) the name of such person, together with such consents and
information concerning present and prior occupations, transactions with the
Corporation or its subsidiaries and other matters as may at the time be required
by or pursuant to the By-laws, shall have been filed with the Secretary of the
Corporation no later than a time faced by or pursuant to the By-laws immediately
preceding the annual or special meeting at which such person intends to be a
candidate for director.

      5.3 Removal of Directors. Directors of the Corporation may only be removed
for cause by a vote of the holders of shares entitled to cast a majority of the
votes which all stockholders are entitled to cast at an election of directors.
No decrease or increase in the size of the Board of Directors shall shorten or
otherwise affect the term of any incumbent director.

      5.4 Elections of Directors. Elections of directors need not be by written
ballot unless the By-laws of the Corporation shall so provide.

SIXTH: Unanimous Consent of Stockholders in Lieu of Meeting. Any action required
to be taken at any annual or special meeting of stockholders of the Corporation,
or any action which may be taken at any annual or special meeting of such
stockholders, may be taken without a meeting, without prior notice and without a
vote, if a consent or consents in writing, setting forth the action so taken,
shall be signed by the holders of all of the outstanding stock entitled to vote
to take such action at any annual or special meeting of stockholders of the
Corporation and shall be delivered to the Corporation by delivery to its
registered office in Delaware, its principal place of business, or an officer or
agent of the Corporation having custody of the books in which proceedings of
meetings of stockholders are recorded. Every written consent shall bear the date
of signature of each stockholder who signs the consent and no written consent
shall be effective to take the corporate action referred to therein unless,
within 60 days of the earliest dated consent delivered in the manner required in
this section to the Corporation, written consents signed by the holders of all
of the outstanding stock entitled to vote to take such action are delivered to
the Corporation by delivery to its registered office in Delaware, its principal
place of business, or an officer or agent of the Corporation having custody of
the book in which proceedings of meetings of stockholders are recorded. Delivery
made to the Corporation's registered office shall be by hand or by certified or
registered mail, return receipt requested.

SEVENTH: By-laws. The Board of Directors shall have the power, in addition to
the stockholders, to make, alter, or repeal the By-laws of the Corporation.

EIGHTH: Liability of Directors. A director of the Corporation shall not be
personally liable to the Corporation or its stockholders for monetary damages
for breach of fiduciary duty as a director, except for liability (i) for any
breach of the director's duty of loyalty to the Corporation or its stockholders,
(ii) for acts or omissions not in good faith or which


                                     II-17


involve intentional misconduct or a knowing violation of law, (iii) under
Section 174 of the Delaware General Corporation Law, as the same exists or
hereafter may be amended, or (iv) for any transaction from which the director
derived an improper personal benefit. If the Delaware General Corporation Law is
hereafter amended to authorize corporate action further limiting or eliminating
the personal liability of directors, then the liability of a director to the
corporation shall be limited or eliminated to the fullest extent permitted by
the Delaware General Corporation Law, as so amended from time to time. Any
repeal or modification of this Article EIGHTH shall be by prospective only, and
shall not adversely affect any limitation on the personal liability of a
director of the Corporation existing at the time of such repeal or modification.

NINTH: Indemnification. The Corporation shall, to the fullest extent permitted
by the Delaware General Corporation Law, as the same may be amended and
supplemented, indemnify any and all past, present and future directors and
officers of the Corporation from and against any and all costs, expenses
(including attorneys' fees), damages, judgments, penalties, fines, punitive
damages, excise taxes assessed with respect to an employee benefit plan and
amounts paid in settlement in connection with any action, suit or proceeding,
whether by or in the right of the Corporation, a class of its security holders
or otherwise, in which the director or officer may be involved as a party of
otherwise, by reason of the fact that such person was serving as a director,
officer, employee or agent of the Corporation.

TENTH. Fundamental Transactions.

      10.1 Stockholder Authorization of Fundamental Transactions Recommended by
Management. Whenever any corporate action which constitutes a Fundamental
Transaction is to be taken by vote of the stockholders and such Fundamental
Transaction has been approved by at least two-thirds of the entire Board of
Directors, the proposed Fundamental Transaction shall be authorized upon
receiving the minimum vote required for the authorization of such action by
statute, after taking into account the express terms of any class or any series
of any class of shares of the Corporation with respect to such vote.

      10.2 Stockholder Authorization of Fundamental Transactions Not Recommended
by Management. Except as provided in Section (1) of this Article TENTH, whenever
any corporate action than constitutes a Fundamental Transaction is to be taken
by vote of the stockholders, the proposed Fundamental Transaction shall be
authorized only upon receiving at least two-thirds of the vote which all voting
stockholders, voting as a single class, are entitled to cast thereon and, in
addition, the affirmative vote of the number or proportion of shares of any
class or any series of any class of shares of the Corporation, if any, as shall
at the time be required by statute or the express terms of any such class or
series of any class of shares of the Corporation.

      10.3 Fundamental Transaction Defined. For the purposes of this Article
TENTH, the term "Fundamental Transaction" shall mean:

disposition of all or substantially all of the assets of the Corporation; or the
