                              SECOND AMENDMENT TO
                             AMENDED AND RESTATED
                          COOPER CAMERON CORPORATION
                           LONG-TERM INCENTIVE PLAN

     WHEREAS, COOPER CAMERON CORPORATION (the "Company") has heretofore adopted
the AMENDED AND RESTATED COOPER CAMERON CORPORATION LONG-TERM INCENTIVE PLAN
(the "Plan"); and

     WHEREAS, the Company desires to amend the Plan in certain respects;

     NOW, THEREFORE, the Plan shall be amended as follows, effective as of May
13, 1999:

     1.   Section 14.3 shall be added to the Plan:

          "In addition to any other rights or privileges held by a
          holder with respect to an Award that is an option (including
          the provisions of Section 14.2), upon a Change in Control of
          the Company, the holder shall have the right to exchange
          such option for a new option ("New Option") that shall be
          issued according to the following:

          (1)  the New Option shall be immediately exercisable;

          (2)  the New Option shall have a term equal to the remaining
               term of the LTIP Option it replaces (and shall be
               exercisable through such term);

          (3)  the New Option will give the holder the right to
               acquire shares of the publicly traded common equity of
               the Company or any successor or direct or indirect
               parent of either ("Replacement Common Stock") (in the
               event of two or more classes of common equity, the
               common equity used shall be determined by the
               Compensation Committee of the Board of Directors of the
               Company existing prior to a Change in Control);

          (4)  the exercise price used for the New Option ("New
               Exercise Price") for acquiring a share of Replacement
               Common Stock shall be determined at the time of the
               Change in Control by taking (i) the higher of (a) the
               aggregate value (as of the date of the Change in
               Control) equal to the
<PAGE>

               merger or acquisition consideration paid or payable in
               the Change in Control, on a per share basis, or (b) the
               highest price paid for a share of Cooper Cameron common
               stock over the New York Stock Exchange (or other
               primary exchange) during the 12 months prior to the
               Change in Control, and (ii) dividing such amount into
               the per share exercise price of the LTIP Option; with
               the result multiplied by the Replacement Common Stock
               closing price on its principal stock exchange on the
               day of the Change in Control, or if traded in the over-
               the-counter market and not on an exchange, the last bid
               price in such market;

          (5)  the number of shares of Replacement Common Stock subject
               to the New Option shall be the number necessary, using
               the New Exercise Price, to provide an aggregate value
               (as of the date of the Change in Control) equal to the
               higher of (a) the merger or acquisition consideration
               paid or payable in the Change in Control on a per share
               basis, or (b) the highest price paid for a share of
               Cooper Cameron common stock over the New York Stock
               Exchange (or other primary exchange) during the 12
               months prior to the Change in Control;

          (6)  if there is no publicly traded common equity of the
               Company, or any successor or any direct or indirect
               parent of either, then the New Option shall be with
               respect to shares of the direct or indirect parent of
               the Company, and if no such parent then the Company,
               and if the Company no longer exists, then the successor
               to the Company.

     2.   Section 14.4 shall be added to the Plan:

          "The Board may determine, in connection with an event described in
          Sections 14.2 or 14.3, to provide with respect to Awards other
          adjustments, rights or privileges, including adjustments, rights or
          privileges that are alternatives to those provided in Sections 14.2
          and 14.3, but unless such adjustments, rights or privileges are
          cumulative to those in Sections 14.2 and 14.3, they will be applicable
          only with the consent of the holder of an Award.

     3.   As amended hereby, the Plan is specifically ratified and reaffirmed.

                                        /s/ Franklin Myers

(iii)    The consummation of a merger, consolidation or

acquired the ownership of any of the Corporation’s then outstanding voting
securities solely in connection with a public offering of the Corporation’s
securities, (2) the Corporation or an affiliate of the Corporation, or (3) an

less than the F Division Amount and (ii) in the event of a conversion pursuant
to Section 5.1.1(c) the F Current Market Price shall be deemed to be $22.00. The

or other securities which are convertible into or exchangeable, with or without
payment of additional consideration in cash or property, for Common Stock,

day period shall end ten (10) Trading Days after (i) the date the Corporation
sends a press release to the public announcing the termination of the License

date of such termination; provided, however, that if conversion is made pursuant

sales price on the principal exchange on which the Common Stock is listed, or,
if it is not so listed, the Nasdaq National Market or, if it is not so listed,
on the over-the-counter market.

         1.6.    "F
Division Amount" shall mean $10.00 (as adjusted pursuant to Section 5).

         1.7.    "F
Junior Stock" shall mean the Common Stock and any other class or series of

         1.8.   
"License Agreement" shall mean that certain License Agreement dated as of May

prices reflecting such trading are published by the National Association of
Securities Dealers Automated Quotation System.

         2.   
Dividends. Series F Preferred Stock shall not be entitled to receive any
dividends (other than dividends payable in F Junior Stock or distributions
pursuant to Section 5.6).

         3.   
Liquidation or Dissolution.

         3.1.   Rank.
The Series F Preferred Stock of the Corporation shall rank on a parity with the
Series A Preferred Stock, the Series G Preferred Stock and the Series H
Preferred Stock as to distributions upon a liquidation, dissolution or winding
up of the Corporation and any other preferred stock issued by the Corporation.

         3.2.   
Preference. Subject to the prior rights of the Corporation's creditors and
holders of securities senior to the Series F Preferred Stock in respect of
distributions upon liquidation, dissolution or winding-up of the Corporation, in
the event of the voluntary or involuntary liquidation, dissolution or winding-up
of the Corporation, the holders of Series F Preferred Stock shall be entitled to
receive forty dollars $40.00 per share. If, upon any such liquidation,
dissolution or winding-up of the Corporation, the assets distributable among the
holders of Series F Preferred Stock (and any series of preferred stock ranking
in parity with the Series F Preferred Stock in respect of distributions upon
liquidation, dissolution or winding-up of the Corporation) shall be insufficient
to permit the payment in full to such holders of the preferential amount payable
to such holders determined as aforesaid, then the holders of Series F Preferred
Stock (and any such series) will share ratably in any distribution of the
Corporation's assets in proportion to the respective preferential amounts that
would have been payable if such assets were sufficient to permit payment in full
of all such amounts. After payment of the full amount of the liquidating
distribution to which the holders of Series F Preferred Stock are entitled,
holders of F Junior Stock (other than Common Stock) shall be paid any
preferential amounts payable to such holders. Thereafter, the holders of Series
F Preferred Stock will share pro rata with the holders of Common Stock (and the
holders of F Junior Stock entitled to share pro rata with Common Stock in
liquidating distributions), based on the number of shares of Common Stock into
which the Series F Preferred Stock is then convertible, any further distribution
of assets by the Corporation. Under this Section 3, a distribution of assets in
any dissolution, winding-up or liquidation shall not include (a) any
consolidation or merger of the Corporation with or into any other corporation,
(b) any dissolution, liquidation or winding-up of the Corporation immediately
followed by reincorporation of a successor corporation or (c) a sale or other
disposition of all or substantially all of the Corporation's assets in
consideration for the issuance of equity securities of another corporation,
provided that the consolidation, merger, dissolution, liquidation, winding-up,
sale or other disposition (i) does not amend, alter, or change the preferences
or rights of the Series F Preferred Stock or the qualifications, limitations or
restrictions thereof in a manner that adversely affects the Series F Preferred
Stock or (ii) is done in accordance with Sections 5.5, 5.6 or 5.7 hereof.

         4.    Voting
Rights. The holders of Series F Preferred Stock shall not be entitled to any
voting rights except as otherwise required by law.

        5.   Conversion Rights.

         5.1.   
Conversion of Series F Preferred Stock. The Series F Preferred Stock shall
convert into fully paid and non-assessable shares of Common Stock as follows:

             
5.1.1.    The Series F Preferred Stock shall convert at the F
Conversion Rate into Common Stock on the earlier of the following; provided that
once the F Current Market Price per share of Common Stock is equal to or greater
than $22, subject to adjustment pursuant to Section 5.5, the F Current Market
Price shall be deemed fixed at $22 (subject to such adjustment) for all
conversions of the Series F Preferred Stock hereunder.

                  
(a)    At the option of a holder of the Series F Preferred Stock,
exercisable on or after May 19, 2004, such holder's Series F Preferred Stock
shall convert;

                  
(b)    (i) Termination of the License Agreement other than
pursuant to Section 5.1.1(b)(ii) below or (ii) termination of the License
Agreement by PFC pursuant to Section 10.3(a) thereof, (in either case, unless
termination of the License Agreement is as a result of the liquidation of the
Corporation, the appointment of a receiver or trustee for substantially all of
the property or assets of the Corporation, or the Corporation makes an
assignment for the benefit of creditors, in each case, in accordance with the
License Agreement);

                  
(c)    At the option of a holder of the Series F Preferred Stock,
such holder’s Series F Preferred Stock shall convert at any time that the F
Current Market Price per share of Common Stock is equal to or greater than
$22.00, subject to adjustment pursuant to Section 5.5; or

                  
(d)    At the option of a holder of the Series F Preferred Stock,
such holder’s Series F Preferred Stock shall convert upon a Change of
Control of the Corporation.

             
5.2.    Issuance Limitation. If, pursuant to Section 5 of
Article 4(g), Section 6 of Article 4(h) or Section 6 of Article 4(i), a
conversion event occurs or a conversion election is made and conversion of
shares of Series F Preferred Stock, Series G Preferred Stock or Series H
Preferred Stock (the shares of the three series collectively, the "Preferred
Shares") subject to such section would, when taken together with the conversion
of any other Preferred Shares, result in the issuance by the Company of a number
of shares (the "Additional Shares") of its Common Stock greater than the
"Issuance Limit," then the Company need not issue the Additional Shares, unless
it first obtains shareholder approval of the issuance of the Additional Shares.
"Issuance Limit" means 9,389,477 shares of Common Stock (that is, 19.9% of the
shares of Common Stock issued and outstanding as of May 16, 2000), as such
number may be adjusted pursuant to Sections 5.5 of Article 4(g), Section 6.5 of
Article 4(h) or Section 6.5 of Article 4(i). If the Company does not obtain
shareholder approval for the issuance of the Additional Shares or, in any event,
does not, prior to the expiration of 120 days after such conversion event or
conversion election, issue the Additional Shares required to be issued as a
result of such conversion event or conversion election, the Company shall pay to
each person entitled to receive such Additional Shares an amount in cash equal
to the aggregate market price of such Additional Shares on the day that the
conversion event occurred or the conversion election was made. The market price
for such day shall be the last reported sales price on the principal exchange on
which the Common Stock is listed, or, if it is not so listed, the Nasdaq
National Market or, if it is not so listed, on the over-the-counter market.

             
5.3.    Conversion Procedure. Upon conversion of Series F
Preferred Stock, the shares so converted shall have the status of authorized and
unissued preferred stock, and the number of shares of preferred stock which the
corporation shall have authority to issue shall include the number of shares of
Series F Preferred Stock so converted. Upon any conversion, certificates
representing the Series F Preferred Stock shall thereafter be deemed to
represent the appropriate number of shares of Common Stock into which such stock
is converted. After conversion the holder of any shares of Series F Preferred
Stock so converted shall deliver to the Corporation during regular business
hours, at such place as may be designated by the Corporation, the certificate or
certificates for the shares to be converted, duly endorsed or assigned in blank,
or to the Corporation (if required by it), accompanied by written notice stating
the name or names (with address) in which the certificate or certificates for
the shares of Common Stock are to be issued.

             
5.4.    Fractional Shares. No fractional shares of Common
Stock or scrip shall be issued upon conversion of shares of Series F Preferred
Stock. If more than one share of Series F Preferred Stock shall be surrendered
for conversion at any one time by the same holder, the number of full shares of
Common Stock issuable upon conversion thereof shall be computed on the basis of
the aggregate number of shares so surrendered. Instead of any fractional shares
of Common Stock which would otherwise be issuable upon any such conversion, the
Corporation shall pay a cash adjustment in respect of such fractional interest
in an amount determined on the basis of the then current fair market value of a
share of Common Stock as determined by the Board of Directors of the
Corporation, in good faith. Fractional interests shall not be entitled to
dividends, and the holders thereof shall not be entitled to any rights as
stockholders of the Corporation in respect of such fractional interests.

             
5.5.   Adjustments for Subdivisions, Stock Dividends,
Combinations, or Consolidations of Common Stock. In the event the
outstanding shares of Common Stock shall be increased by way of stock issued as
a dividend for no consideration or subdivided (by stock split, or otherwise)
into a greater number of shares of Common Stock, the F Division Amount and the
per share amount specified in Section 1.3(ii) and Section 5.1.1(c) then in
effect shall, concurrently with the effectiveness of such increase or
subdivision, be proportionately decreased and the number of shares constituting
the Issuance Limit shall be proportionally increased. In the event the
outstanding shares of Common Stock shall be combined or consolidated, by
reclassification or otherwise, into a lesser number of shares of Common Stock,
the F Division Amount and the per share amount specified in Section 1.3(ii) and
Section 5.1.1(c) then in effect shall, concurrently with the effectiveness of
such combination or consolidation, be proportionately increased and the number
of shares constituting the Issuance Limit shall be proportionally decreased.

             
5.6.   Other Distributions. If for any reason, including
without limitation a merger or sale of assets transaction, the Corporation shall
declare a distribution payable in securities of the Corporation, or in
securities of other persons, evidences of indebtedness issued by the Corporation
or other persons, or assets (excluding cash dividends) then, in each such case
for the purpose of this Section 5.6, the holders of the Series F Preferred Stock
shall be entitled to a proportionate share of such distribution as though they
were the holders of the number of shares of Common Stock of the Corporation into
which their shares of Series F Preferred Stock would be convertible as of the
record date fixed for the determination of the holders of Common Stock of the
Corporation entitled to receive such distribution.

             
5.7.   Reorganizations and Recapitalizations. If at any
time or from time to time there shall be a reorganization or recapitalization of
the Common Stock (other than a subdivision, combination or merger or sale of
assets transaction provided for in Section 5.5 or Section 5.6 above), then, as a
condition of such reorganization or recapitalization, provision shall be made so
that the holders of the Series F Preferred Stock shall thereafter be entitled to
receive upon conversion of the Series F Preferred Stock, the number of shares of
stock or other securities or property of the Corporation or otherwise to which a
holder of Common Stock deliverable upon conversion would have been entitled on
such reorganization or recapitalization. In any such case, appropriate
adjustment shall be made in the application of the provisions of this Section 5
with respect to the rights of the holders of the Series F Preferred Stock after
the reorganization or recapitalization to the end that the provisions of this
Section 5 (including adjustment of the F Conversion Rate and the F Division
Amount then in effect and the number of shares receivable upon conversion of the
Series F Preferred Stock) shall be applicable after that event in as nearly an
equivalent manner as may be practicable.

             
5.8.   Reservation of Shares. The Corporation agrees that,
so long as any share of Series F Preferred Stock shall remain outstanding, the
Corporation shall at all times reserve and keep available, free from preemptive
rights, out of its authorized capital stock, for the purpose of issue upon
conversion of the Series F Preferred Stock, the full number of shares of Common
Stock then issuable upon conversion of all outstanding shares of Series F
Preferred Stock. If the Common Stock shall be listed on any national securities
exchange, the Corporation at its expense shall include in a listing application
all of the shares of Common Stock reserved for issuance upon conversion of the
Series F Preferred Stock, (subject to issuance or notice of issuance to the
exchange) and will similarly apply for and use its best efforts to procure the
listing of any further Common Stock reserved for issuance upon conversion of the
Series F Preferred Stock, at any subsequent time as a result of adjustments in
the F Conversion Rate or otherwise.

             
5.9.   Validity of Shares. The Corporation agrees that it
will from time to time take all such actions as may be requisite to assure that
all shares of Common Stock which may be issued upon conversion of any share of
the Series F Preferred Stock will, upon issuance, be legally and validly issued,
fully paid and non-assessable and free from all taxes, liens and charges with
respect to the issue thereof.

             
5.10.   Taxes. The Corporation will pay all taxes and
other governmental charges that may be imposed in respect of the issue or
delivery (but not transfer) of shares of Common Stock upon conversion of the
Series F Preferred Stock.

             
5.11.   Abandonment of Action. If the Corporation shall
take a record of the holders of its Common Stock for the purpose of entitling
them to receive a dividend or distribution requiring an adjustment pursuant to
Section 5 and shall, thereafter and before the distribution to stockholders
thereof, legally abandon its plan to pay or deliver such dividend or
distribution, then thereafter no adjustment to the holders of Series F Preferred
Stock shall be required by reason of the taking of such record and any such
adjustment previously made in respect thereof shall be rescinded and annulled.

             
5.12.   Notice Provisions.

                  
5.12.1.   Whenever an adjustment is required pursuant to Section
5 hereof, the Corporation shall forthwith deliver to the holders of Series F
Preferred Stock, a certificate signed by an officer of the Corporation, setting
forth, in reasonable detail, the event requiring the adjustment, the method by
which such adjustment was calculated and the adjustments made.

                  
5.12.2.   In case the Corporation shall propose (a) to pay any
dividend payable in stock of any class to the holders of F Junior Stock or to
make any other distribution to the holders of its Common Stock, (b) to offer to
the holders of its Common Stock rights to subscribe for or to purchase any
Convertible Securities, Common Stock or shares of stock of any class or any
other securities, rights or options, (c) to effect any reclassification of its
Common Stock (other than a reclassification involving only the subdivision or
combination of outstanding shares of Common Stock), (d) to effect any capital
reorganization, (e) to effect any consolidation, merger or sale, transfer or
other distribution of all or substantially all its property, assets or business,
or (f) to effect the liquidation, dissolution or winding-up of the Corporation,
then, in each such case, the Corporation shall give to each holder of Series F
Preferred Stock a notice of such proposed action, which shall specify the date
on which a record is to be taken for the purposes of such stock dividend,
distribution or rights, or the date on which such reclassification,
reorganization, consolidation, merger, sale, transfer, disposition, liquidation,
dissolution or winding-up is to take place and the date of participation therein
by the holders of Common Stock, if any such date is to be fixed, and shall also
set forth such facts with respect thereto as shall be reasonably necessary to
indicate the effect of such action on the Common Stock and the F Conversion Rate
and the F Division Amount after giving effect to any adjustment which will be
required as a result of such action. Such notice shall be so given in the case
of any action covered by (a) or (b) above at least ten (10) days prior to the
record date for determining holders of the Common Stock for purposes of such
action and, in the case of any other such action, at least ten (10) days prior
to the date of the taking of such proposed action or the date of participation
therein by the holders of Common Stock, whichever shall be the earlier.

        6.   No
Pre-emptive Rights. No holder of Series F Preferred Stock shall have any
pre-emptive or preferential right of subscription to any shares of stock of the
Corporation, or to options, warrants or other interests therein or therefor, or
to any obligations convertible into stock of the Corporation, issued or sold, or
any right of subscription to any thereof other than such, if any, as the Board
of Directors, in its discretion, from time to time may determine and at such
price or prices as the Board of Directors from time to time may fix pursuant to
the authority conferred by the Corporation’s Certificate of
Incorporation.

        7.   Covenants.
In addition to any other rights provided by law, so long as any shares of Series
F Preferred Stock are outstanding, this Corporation shall not, without first
obtaining the affirmative vote or written consent of the holders of not less
than sixty-six and two-thirds percent (66-2/3%) of the Series F Preferred Stock:

             
(a)    Amend or repeal any provisions of the Corporation's
Certificate of Incorporation which action would adversely affect the rights,
preferences, or privileges of the Series F Preferred Stock; or

             
(b)    Alter or change the designations, powers, rights,
preferences or privileges, or the qualification, limitations or restrictions of
the Series F Preferred Stock; or

             
(c)    Increase the authorized number of shares of Series F
Preferred Stock or other preferred stock of the Corporation; or

             
(d)      Authorize, create, or issue any Series A
Preferred Stock, or any new class or series of stock or any other securities
convertible into equity securities of the Corporation having a preference over
the Series F Preferred Stock with respect to dividends, redemptions or upon
liquidation or dissolution of the Corporation; or

             
(e)    Reclassify the shares of Common Stock or any other F
Junior Stock into shares of any class or series of capital stock (i) ranking
either as to payment of dividends, distribution of assets or redemptions, prior
to or on parity with the Series F Preferred Stock, or (ii) which in any manner
adversely affects the holders of Series F Preferred Stock.

	        (B)   a merger, consolidation or reorganization in which no Person is or becomes
the Beneficial Owner, directly or indirectly, of securities of the Corporation
representing 20% or more of the combined voting power of the Corporation's then

(iv)    The stockholders of the Corporation approve a plan of
complete liquidation of the Corporation or an agreement for the sale or other
disposition by the Corporation of all or substantially all of the Corporation's
assets.

        
      Notwithstanding the preceding provisions of this
definition, a Change in Control shall not be deemed to have occurred if the
Person described in the preceding provisions is (1) an underwriter or
underwriting syndicate that has acquired the ownership of any of the
Corporation's then outstanding voting securities solely in connection with a
public offering of the Corporation's securities, (2) the Corporation or an
affiliate of the Corporation, or (3) an employee stock ownership plan or other

1.5.    "G Redemption Price" shall mean $1,100 per share plus any dividends accrued
on or before the date of the G Redemption Notice.

the National Association of Securities Dealers Automated Quotation System.

        2.   Dividends.
Before any dividends (other than dividends payable in Common Stock) on any G
Junior Stock shall be declared or paid or set apart for payment, the holders of
shares of Series G Preferred Stock shall be entitled to receive cash dividends,
when and as declared by the Board of Directors from the date of issuance through
March 15, 2005, at the annual rate of $82.50 per share, and no more. Dividends
on the Series G Preferred Stock shall accumulate on an annual compounded basis
(based on actual days elapsed over 365/366) and any accumulated dividends shall
be payable to a holder of record on the earlier of: (i) redemption by the
Corporation of such holder’s Series G Preferred Stock or (ii) March 31,
2005. The Series G Preferred Stock shall rank on a parity with the Series H
Preferred Shares as to dividends. Whenever, at any time, the accrued dividends
shall have been paid or declared and set apart for payment on the then
outstanding Series G Preferred Stock, the Board of Directors may declare
dividends on any G Junior Stock, subject to the respective terms and provisions
(if any) applying thereto.

         3.   
Liquidation or Dissolution.

             
3.1.   Rank. The Series G Preferred Stock of the Corporation shall rank on a
parity with the Series A Preferred Stock, the Series F Preferred Stock and the
Series H Preferred Stock as to distributions upon a liquidation, dissolution or
winding up of the Corporation and any other preferred stock of the Corporation.

             
3.2.   Preference. Subject to the prior rights of the
Corporation's creditors and holders of securities senior to the Series G
Preferred Stock in respect of distributions upon liquidation, dissolution or
winding-up of the Corporation, in the event of the voluntary or involuntary
liquidation, dissolution or winding-up of the Corporation, the holders of Series
G Preferred Stock shall be entitled to receive one thousand one hundred dollars
($1,100) per share, plus an amount equal to any accumulated dividends through
the date of such liquidation, dissolution or winding-up. The amount of dividends
"accumulated" on any share of Series G Preferred Stock as at any annual dividend
date shall be deemed to be the amount of any unpaid dividends accumulated
thereon to and including such annual dividend date, whether or not earned or
declared, and the amount of dividends "accumulated" on any share of Series G
Preferred Stock as at any date other than an annual dividend date shall be
calculated in accordance with Section 2 of this Article 4(h). If, upon any such
liquidation, dissolution or winding-up of the Corporation, the assets
distributable among the holders of Series G Preferred Stock (and any series of
preferred stock ranking in parity with the Series G Preferred Stock in respect
of distributions upon liquidation, dissolution or winding-up of the Corporation)
shall be insufficient to permit the payment in full to such holders of the
preferential amount payable to such holders determined as aforesaid, then the
holders of Series G Preferred Stock (and any such series) will share ratably in
any distribution of the Corporation's assets in proportion to the respective
preferential amounts that would have been payable if such assets were sufficient
to permit payment in full of all such amounts. After payment of the full amount
of the liquidating distribution to which the holders of Series G Preferred Stock
are entitled, holders of G Junior Stock (other than Common Stock) shall be paid
any preferential amounts payable to such holders. Thereafter, the holders of
Series G Preferred Stock will share pro rata with the holders of Common Stock
(and the holders of G Junior Stock entitled to share pro rata with Common Stock
in liquidating distributions), based on the number of shares of Common Stock
into which the Series G Preferred Stock is then convertible, any further
distribution of assets by the Corporation. Under this Section 3, a distribution
of assets in any dissolution, winding-up or liquidation shall not include (a)
any consolidation or merger of the Corporation with or into any other
corporation, (b) any dissolution, liquidation or winding-up of the Corporation
immediately followed by reincorporation of a successor corporation or (c) a sale
or other disposition of all or substantially all of the Corporation's assets in
consideration for the issuance of equity securities of another corporation,
provided that the consolidation, merger, dissolution, liquidation, winding-up,
sale or other disposition (i) does not amend, alter, or change the preferences
or rights of the Series G Preferred Stock or the qualifications, limitations or
restrictions thereof in a manner that adversely affects the Series G Preferred
Stock or (ii) is done in accordance with Sections 6.4, 6.5 or 6.6 hereof.

         4.    Voting
Rights. The holders of Series G Preferred Stock shall not be entitled to any
voting rights except as otherwise required by law.

         5.   
Redemption.

             
(a)    At the Corporation's option, from the date the Series G
Preferred Stock is issued until all the Series G Preferred Stock is converted,
all outstanding and unconverted Series G Preferred Stock may be redeemed by the
Corporation pursuant to this Section 5(a), from funds legally available therefor
at the G Redemption Price. The Corporation shall provide at least 10 days and
not more than 30 days advance written notice of redemption to each holder of the
Series G Preferred Stock (a "G Redemption Notice"), which notice shall set forth
the date (the "Redemption Date") fixed for such redemption; provided that any G
Redemption Notice given after March 15, 2005 shall be given at least 30 days and
not more than 45 days in advance of the Redemption Date stated therein.

             
(b)    The entire redemption price of the shares of Series G
Preferred Stock outstanding on a Redemption Date shall be paid in cash on such
Redemption Date. If any portion of the applicable G Redemption Price under
Section 6(a) shall not be paid by the Corporation within ten (10) calendar days
after the date due, interest shall accrue thereon at the rate of 7.5% per annum
until the redemption price plus all such interest is paid in full (which amount
shall be paid as liquidated damages and not as a penalty).

        6.   Conversion Rights.

             
6.1.   Conversion of Series G Preferred Stock. At the
option of a holder of the Series G Preferred Stock, each share of such holder's
Series G Preferred Stock shall convert into one hundred fully paid and
non-assessable shares of Common Stock:

                  
6.1.1.    Until the close of business on the date preceding the
Redemption Date on or after March 15, 2005; or

                  
6.1.2.    Upon a Change of Control of the Corporation.

             
6.2.   Issuance Limitation. If, pursuant to Section 5 of
Article 4(g), Section 6 of Article 4(h) or Section 6 of Article 4(i), a
conversion event occurs or a conversion election is made and conversion of
shares of Series F Preferred Stock, Series G Preferred Stock or Series H
Preferred Stock (the shares of the three series collectively, the "Preferred
Shares") subject to such section would, when taken together with the conversion
of any other Preferred Shares, result in the issuance by the Company of a number
of shares (the "Additional Shares") of its Common Stock greater than the
"Issuance Limit," then the Company need not issue the Additional Shares, unless
it first obtains shareholder approval of the issuance of the Additional Shares.
"Issuance Limit" means 9,389,477 shares of Common Stock (that is, 19.9% of the
shares of Common Stock issued and outstanding as of May 16, 2000), as such
number may be adjusted pursuant to Sections 5.5 of Article 4(g), Section 6.5 of
Article 4(h) or Section 6.5 of Article 4(i). If the Company does not obtain
shareholder approval for the issuance of the Additional Shares or, in any event,
does not, prior to the expiration of 120 days after such conversion event or
conversion election, issue the Additional Shares required to be issued as a
result of such conversion event or conversion election, the Company shall pay to
each person entitled to receive such Additional Shares an amount in cash equal
to the aggregate market price of such Additional Shares on the day that the
conversion event occurred or the conversion election was made. The market price
for such day shall be the last reported sales price on the principal exchange on
which the Common Stock is listed, or, if it is not so listed, the Nasdaq
National Market or, if it is not so listed, on the over-the-counter market.

             6.3.   Conversion Procedure. Upon conversion of Series G Preferred
Stock, the shares so converted shall have the status of authorized and unissued
preferred stock, and the number of shares of preferred stock which the
corporation shall have authority to issue shall include the number of shares of
Series G Preferred Stock so converted. Upon any conversion, certificates
representing the Series G Preferred Stock shall thereafter be deemed to
represent the appropriate number of shares of Common Stock into which such stock
is converted. After conversion the holder of any shares of Series G Preferred
Stock so converted shall deliver to the Corporation during regular business
hours, at such place as may be designated by the Corporation, the certificate or
certificates for the shares to be converted, duly endorsed or assigned in blank,
or to the Corporation (if required by it), accompanied by written notice stating
the name or names (with address) in which the certificate or certificates for
the shares of Common Stock are to be issued.

             6.4.   Fractional
Shares. No fractional shares of Common Stock or scrip shall be issued upon
conversion of shares of Series G Preferred Stock. If more than one share of
Series G Preferred Stock shall be surrendered for conversion at any one time by
the same holder, the number of full shares of Common Stock issuable upon
conversion thereof shall be computed on the basis of the aggregate number of
shares so surrendered. Instead of any fractional shares of Common Stock which
would otherwise be issuable upon any such conversion, the Corporation shall pay
a cash adjustment in respect of such fractional interest in an amount determined
on the basis of the then current fair market value of a share of Common Stock as
determined by the Board of Directors of the Corporation, in good faith.
Fractional interests shall not be entitled to dividends, and the holders thereof
shall not be entitled to any rights as stockholders of the Corporation in
respect of such fractional interests. 

             6.5.   Adjustments
for Subdivisions, Stock Dividends, Combinations, or Consolidations of Common
Stock. In the event the outstanding shares of Common Stock shall be
increased by way of stock issued as a dividend for no consideration or
subdivided (by stock split, or otherwise) into a greater number of shares of
Common Stock, the number of shares of Common Stock issuable upon conversion of
the Series G Preferred Stock then outstanding shall, concurrently with the
effectiveness of such increase or subdivision, be proportionately increased and
the number of shares constituting the Issuance Limit shall be proportionally
increased. In the event the outstanding shares of Common Stock shall be combined
or consolidated, by reclassification or otherwise, into a lesser number of
shares of Common Stock, the number of shares of Common Stock issuable upon
conversion of the Series G Preferred Stock then outstanding shall, concurrently
with the effectiveness of such combination or consolidation, be proportionately
decreased and the number of shares constituting the Issuance Limit shall be
proportionally decreased.

              6.6.  Other
Distributions. If for any reason, including without limitation a merger or sale
of assets transaction, the Corporation shall declare a distribution payable in
securities of the Corporation, or in securities of other persons, evidences of
indebtedness issued by the Corporation or other persons, or assets (excluding
cash dividends) then, in each such case for the purpose of this Section 6.6, the
holders of the Series G Preferred Stock shall be entitled to a proportionate
share of such distribution as though they were the holders of the number of
shares of Common Stock of the Corporation into which their shares of Series G
Preferred Stock would be convertible as of the record date fixed for the
determination of the holders of Common Stock of the Corporation entitled to
receive such distribution. 

             6.7.   Reorganizations and Recapitalizations. If at any time or from time to time
there shall be a reorganization or recapitalization of the Common Stock (other
than a subdivision, combination or merger or sale of assets transaction provided
for in Section 6.5 or Section 6.6 above), then, as a condition of such
reorganization or recapitalization, provision shall be made so that the holders
of the Series G Preferred Stock shall thereafter be entitled to receive upon
conversion of the Series G Preferred Stock, the number of shares of stock or
other securities or property of the Corporation or otherwise to which a holder
of Common Stock deliverable upon conversion would have been entitled on such
reorganization or recapitalization. In any such case, appropriate adjustment
shall be made in the application of the provisions of this Section 6 with
respect to the rights of the holders of the Series G Preferred Stock after the
reorganization or recapitalization to the end that the provisions of this
Section 6 (including adjustment to the number of shares of Common Stock
receivable upon conversion of the Series G Preferred Stock) shall be applicable
after that event in as nearly an equivalent manner as may be practicable. 

             6.8.   Reservation
of Shares. The Corporation agrees that, so long as any share of Series G
Preferred Stock shall remain outstanding, the Corporation shall at all times
reserve and keep available, free from preemptive rights, out of its authorized
capital stock, for the purpose of issue upon conversion of the Series G
Preferred Stock, the full number of shares of Common Stock then issuable upon
conversion of all outstanding shares of Series G Preferred Stock. If the Common
Stock shall be listed on any national securities exchange, the Corporation at
its expense shall include in a listing application all of the shares of Common
Stock reserved for issuance upon conversion of the Series G Preferred Stock,
(subject to issuance or notice of issuance to the exchange) and will similarly
apply for and use its best efforts to procure the listing of any further Common
Stock reserved for issuance upon conversion of the Series G Preferred Stock, at
any subsequent time as a result of adjustments in the number of shares of Common
Stock issuable upon conversion of the Series G Preferred Stock. 

             6.9.   Validity of
Shares. The Corporation agrees that it will from time to time take all such
actions as may be requisite to assure that all shares of Common Stock which may
be issued upon conversion of any share of the Series G Preferred Stock will,
upon issuance, be legally and validly issued, fully paid and non-assessable and
free from all taxes, liens and charges with respect to the issue thereof. 

             6.10.   Taxes.
The Corporation will pay all taxes and other governmental charges that may be
imposed in respect of the issue or delivery (but not transfer) of shares of
Common Stock upon conversion of the Series G Preferred Stock.

             6.11.   Abandonment
of Action. If the Corporation shall take a record of the holders of its
Common Stock for the purpose of entitling them to receive a dividend or
distribution requiring an adjustment pursuant to Section 6 and shall, thereafter
and before the distribution to stockholders thereof, legally abandon its plan to
pay or deliver such dividend or distribution, then thereafter no adjustment to
the holders of Series G Preferred Stock shall be required by reason of the
taking of such record and any such adjustment previously made in respect thereof
shall be rescinded and annulled. 

             6.12.   Notice Provisions.

                  6.12.1.   Whenever
an adjustment is required pursuant to Section 6 hereof, the Corporation shall
forthwith deliver to the holders of Series G Preferred Stock, a certificate
signed by an officer of the Corporation, setting forth, in reasonable detail,
the event requiring the adjustment, the method by which such adjustment was
calculated and the adjustments made. 

                  6.12.2.    In case the Corporation shall propose (a) to pay any dividend payable in
stock of any class to the holders of G Junior Stock or to make any other
distribution to the holders of its Common Stock, (b) to offer to the holders of
its Common Stock rights to subscribe for or to purchase any Convertible
Securities, Common Stock or shares of stock of any class or any other
securities, rights or options, (c) to effect any reclassification of its Common
Stock (other than a reclassification involving only the subdivision or
combination of outstanding shares of Common Stock), (d) to effect any capital
reorganization, (e) to effect any consolidation, merger or sale, transfer or
other distribution of all or substantially all its property, assets or business,
or (f) to effect the liquidation, dissolution or winding-up of the Corporation,
then, in each such case, the Corporation shall give to each holder of Series G
Preferred Stock a notice of such proposed action, which shall specify the date
on which a record is to be taken for the purposes of such stock dividend,
distribution or rights, or the date on which such reclassification,
reorganization, consolidation, merger, sale, transfer, disposition, liquidation,
dissolution or winding-up is to take place and the date of participation therein
by the holders of Common Stock, if any such date is to be fixed, and shall also
set forth such facts with respect thereto as shall be reasonably necessary to
indicate the effect of such action on the Common Stock and the number of shares
of Common Stock issuable upon conversion of the Series G Preferred Stock after
giving effect to any adjustment which will be required as a result of such
action. Such notice shall be so given in the case of any action covered by (a)
or (b) above at least ten (10) days prior to the record date for determining
holders of the Common Stock for purposes of such action and, in the case of any
other such action, at least ten (10) days prior to the date of the taking of
such proposed action or the date of participation therein by the holders of
Common Stock, whichever shall be the earlier. 

        7.   No
Pre-emptive Rights. No holder of Series G Preferred Stock shall have any
pre-emptive or preferential right of subscription to any shares of stock of the
Corporation, or to options, warrants or other interests therein or therefor, or
to any obligations convertible into stock of the Corporation, issued or sold, or
any right of subscription to any thereof other than such, if any, as the Board
of Directors, in its discretion, from time to time may determine and at such
price or prices as the Board of Directors from time to time may fix pursuant to
the authority conferred by the Corporation’s Certificate of Incorporation.

        8.   Covenants.
In addition to any other rights provided by law, so long as any shares of Series
G Preferred Stock are outstanding, this Corporation shall not, without first
obtaining the affirmative vote or written consent of the holders of not less
than sixty-six and two-thirds percent (66-2/3%) of the Series G Preferred Stock:

                  (a)   Amend
or repeal any provisions of the Corporation's Certificate of Incorporation which
action would adversely affect the rights, preferences, or privileges of the
Series G Preferred Stock; or

                  (b) Alter or change the designations, powers, rights, preferences or privileges,

or series of stock or any other securities convertible into equity securities of
the Corporation having a preference over the Series G Preferred Stock with
respect to dividends, redemptions or upon liquidation or dissolution of the
Corporation; or

                  (e)
Reclassify the shares of Common Stock or any other G Junior Stock into shares of
any class or series of capital stock (i) ranking either as to payment of
dividends, distribution of assets or redemptions, prior to or on parity with the
Series G Preferred Stock, or (ii) which in any manner adversely affects the
holders of Series G Preferred Stock.

voting securities of the Corporation or such other entity resulting from the
merger, consolidation or reorganization (the "Surviving Corporation")
outstanding immediately after such merger, consolidation or reorganization and
being held in substantially the same proportion as the ownership in the
Corporation's voting securities immediately before such merger, consolidation or
reorganization, and 

	  
	        
(B) a merger, consolidation or reorganization in which no Person is or becomes
the Beneficial Owner, directly or indirectly, of securities of the Corporation
representing 20% or more of the combined voting power of the Corporation's then
outstanding voting securities; or

             (iv)     The stockholders of the Corporation approve a plan of complete liquidation of the
Corporation or an agreement for the sale or other disposition by the Corporation of all or substantially all of
the Corporation's assets.

             Notwithstanding the preceding provisions of this definition, a Change in Control
shall not be deemed to have occurred if the Person described in the preceding
provisions is (1) an underwriter or underwriting syndicate that has acquired the
ownership of any of the Corporation's then outstanding voting securities solely
in connection with a public offering of the Corporation's securities, (2) the
Corporation or an affiliate of the Corporation, or (3) an employee stock
ownership plan or other employee benefit plan maintained by the Corporation or
any of its affiliates that is qualified under the provisions of the United
States Internal Revenue Code of 1986.

             1.2.    "Common Stock" shall mean the shares of the Common Stock of the
Corporation, par value $.01 per share, and any stock into which such Common
Stock may hereafter be changed.

             1.3.   
"Convertible Securities" shall mean evidences of indebtedness, shares of stock
or other securities which are convertible into or exchangeable, with or without
payment of additional consideration in cash or property, for Common Stock,
either immediately or upon the arrival of a specified date or the happening of a
specified event.

             1.4.    "H Junior Stock" shall mean the Common Stock and any other class or series
of capital stock of the Corporation which at the time of issuance is not
declared to be senior to or on a parity with the Series H Preferred Stock as to
rights upon liquidation or dividends.

             1.5.    "H Redemption Price" shall mean $1,100 per share plus any dividends accrued
on or before the date of the H Redemption Notice.

             1.6.    "Person" shall mean any individual, corporation, association, company,
business trust, partnership, joint venture, joint-stock company, trust,
unincorporated organization or association or government or any agency or
political subdivision thereof.

             1.7.    "Series A Preferred Stock" shall mean the authorized Series A Preferred

Common Stock is then listed or admitted to trading on a national securities
exchange, on the principal national securities exchange on which the Common
Stock is then listed or admitted to trading; or (b) if not, in the
over-the-counter-market and prices reflecting such trading are published by the
National Association of Securities Dealers Automated Quotation System.

        2.  Dividends. Before any dividends (other than
dividends payable in Common Stock) on any H Junior Stock shall be declared or
paid or set apart for payment, the holders of shares of Series H Preferred Stock
shall be entitled to receive cash dividends, when and as declared by the Board
of Directors from the date of issuance through September 15, 2005, at the annual
rate of $82.50 per share, and no more. Dividends on the Series H Preferred Stock
shall accumulate on an annual compounded basis (based on actual days elapsed
365/366) and any accumulated dividends shall be payable to a holder of record on
the earlier of: (i) redemption by the Corporation of such holder’s Series H
Preferred Stock or (ii) September 30, 2005. The Series H Preferred Stock shall
rank on a parity with the Series H Preferred Shares as to dividends. Such
dividends shall be cumulative. Whenever, at any time, accrued dividend shall
have been paid or declared and set apart for payment on the then outstanding
Series H Preferred Stock, the Board of Directors may declare dividends on any H
Junior Stock, subject to the respective terms and provisions (if any) applying
thereto. 

        3.  Liquidation or Dissolution.

             3.1.   Rank. The Series H Preferred Stock of the Corporation shall rank on a
parity with the Series A Preferred Stock, the Series F Preferred Stock and the
Series G Preferred Stock as to distributions upon a liquidation, dissolution or
winding up of the Corporation and any other preferred stock of the Corporation.

             3.2.   Preference. Subject to the prior rights of the Corporation's creditors and
holders of securities senior to the Series H Preferred Stock in respect of
distributions upon liquidation, dissolution or winding-up of the Corporation, in
the event of the voluntary or involuntary liquidation, dissolution or winding-up
of the Corporation, the holders of Series H Preferred Stock shall be entitled to
receive one thousand one hundred dollars ($1,100) per share, plus an amount
equal to any accumulated dividends through the date of such liquidation,
dissolution or winding-up. The amount of dividends “accumulated” on
any share of Series H Preferred Stock as at any annual dividend date shall be
deemed to be the amount of any unpaid dividends accumulated thereon to and
including such annual dividend date, whether or not earned or declared, and the
amount of dividends “accumulated” on any share of Series H Preferred
Stock as at any date other than an annual dividend date shall be calculated in
accordance with Section 2 of this Article 4(i). If, upon any such liquidation,
dissolution or winding-up of the Corporation, the assets distributable among the
holders of Series H Preferred Stock (and any series of preferred stock ranking
in parity with the Series H Preferred Stock in respect of distributions upon
liquidation, dissolution or winding-up of the Corporation) shall be insufficient
to permit the payment in full to such holders of the preferential amount payable
to such holders determined as aforesaid, then the holders of Series H Preferred
Stock (and any such series) will share ratably in any distribution of the
Corporation’s assets in proportion to the respective preferential amounts
that would have been payable if such assets were sufficient to permit payment in
full of all such amounts. After payment of the full amount of the liquidating
distribution to which the holders of Series H Preferred Stock are entitled,
holders of H Junior Stock (other than Common Stock) shall be paid any
preferential amounts payable to such holders. Thereafter, the holders of Series
H Preferred Stock will share pro rata with the holders of Common Stock (and the
holders of H Junior Stock entitled to share pro rata with Common Stock in
liquidating distributions), based on the number of shares of Common Stock into
which the Series H Preferred Stock is then convertible, any further distribution
of assets by the Corporation. Under this Section 3, a distribution of assets in
any dissolution, winding-up or liquidation shall not include (a) any
consolidation or merger of the Corporation with or into any other corporation,
(b) any dissolution, liquidation or winding-up of the Corporation immediately
followed by reincorporation of a successor corporation or (c) a sale or other
disposition of all or substantially all of the Corporation’s assets in
consideration for the issuance of equity securities of another corporation,
provided that the consolidation, merger, dissolution, liquidation, winding-up,
sale or other disposition (i) does not amend, alter, or change the preferences
or rights of the Series H Preferred Stock or the qualifications, limitations or
restrictions thereof in a manner that adversely affects the Series H Preferred
Stock or (ii) is done in accordance with Sections 6.5, 6.6 or 6.7 hereof. 

        4.   Voting Rights. The holders of Series H Preferred Stock shall not be entitled
to any voting rights except as otherwise required by law.

        5.   Redemption.

             (a) At the Corporation's option, from the date the Series H Preferred Stock is
issued until all the Series H Preferred Stock is converted, all outstanding and
unconverted Series H Preferred Stock may be redeemed by the Corporation pursuant
to this Section 5(a), from funds legally available therefor at the H Redemption
Price. The Corporation shall provide at least 10 days and not more than 30 days
advance written notice of redemption to each holder of the Series H Preferred
Stock (a "H Redemption Notice"), which notice shall set forth the date (the
"Redemption Date") fixed for such redemption; provided that any H Redemption
Notice given after September 15, 2005 shall be given at least 30 days and not
more than 45 days in advance of the Redemption Date stated therein.

             (b) The entire redemption price of the shares of Series H Preferred Stock
outstanding shall be paid in cash on such Redemption Date. If any portion of the
applicable H Redemption Price under Section 6(a) shall not be paid by the
Corporation within ten (10) calendar days after the date due, interest shall
accrue thereon at the rate of 7.5% per annum until the redemption price plus all
such interest is paid in full (which amount shall be paid as liquidated damages
and not as a penalty).

        6.   Conversion Rights.

             6.1.   Conversion
of Series H Preferred Stock. At the option of a holder of the Series H
Preferred Stock, each share of such holder's Series H Preferred Stock shall
convert into one hundred fully paid and non-assessable shares of Common
Stock:

                  6.1.1.    Until the close of business on the date preceding the Redemption Date on
or after September 15, 2005; or

                  6.1.2.   Upon a Change of Control of the Corporation.

             6.2.   Issuance
Limitation. If, pursuant to Section 5 of Article 4(g), Section 6 of Article
4(h) or Section 6 of Article 4(i), a conversion event occurs or a conversion
election is made and conversion of shares of Series F Preferred Stock, Series G
Preferred Stock or Series H Preferred Stock (the shares of the three series
collectively, the “Preferred Shares”) subject to such section would,
when taken together with the conversion of any other Preferred Shares, result in
the issuance by the Company of a number of shares (the “Additional
Shares”) of its Common Stock greater than the “Issuance Limit,”
then the Company need not issue the Additional Shares, unless it first obtains
shareholder approval of the issuance of the Additional Shares. “Issuance
Limit” means 9,389,477 shares of Common Stock (that is, 19.9% of the shares
of Common Stock issued and outstanding as of May 16, 2000), as such number may
be adjusted pursuant to Sections 5.5 of Article 4(g), Section 6.5 of Article
4(h) or Section 6.5 of Article 4(i). If the Company does not obtain shareholder
approval for the issuance of the Additional Shares or, in any event, does not,
prior to the expiration of 120 days after such conversion event or conversion
election, issue the Additional Shares required to be issued as a result of such
conversion event or conversion election, the Company shall pay to each person
entitled to receive such Additional Shares an amount in cash equal to the
aggregate market price of such Additional Shares on the day that the conversion
event occurred or the conversion election was made. The market price for such
day shall be the last reported sales price on the principal exchange on which
the Common Stock is listed, or, if it is not so listed, the Nasdaq National
Market or, if it is not so listed, on the over-the-counter market. 

             6.3.   Conversion Procedure. Upon conversion of Series H Preferred Stock, the
shares so converted shall have the status of authorized and unissued preferred
stock, and the number of shares of preferred stock which the corporation shall
have authority to issue shall include the number of shares of Series H Preferred
Stock so converted. Upon any conversion, certificates representing the Series H
Preferred Stock shall thereafter be deemed to represent the appropriate number
of shares of Common Stock into which such stock is converted. After conversion
the holder of any shares of Series H Preferred Stock so converted shall deliver
to the Corporation during regular business hours, at such place as may be
designated by the Corporation, the certificate or certificates for the shares to
be converted, duly endorsed or assigned in blank, or to the Corporation (if
required by it), accompanied by written notice stating the name or names (with
address) in which the certificate or certificates for the shares of Common Stock
are to be issued. 

             6.4.   Fractional Shares. No fractional shares of Common Stock or scrip shall be
issued upon conversion of shares of Series H Preferred Stock. If more than one
share of Series H Preferred Stock shall be surrendered for conversion at any one
time by the same holder, the number of full shares of Common Stock issuable upon
conversion thereof shall be computed on the basis of the aggregate number of
shares so surrendered. Instead of any fractional shares of Common Stock which
would otherwise be issuable upon any such conversion, the Corporation shall pay
a cash adjustment in respect of such fractional interest in an amount determined
on the basis of the then current fair market value of a share of Common Stock as
determined by the Board of Directors of the Corporation, in good faith.
Fractional interests shall not be entitled to dividends, and the holders thereof
shall not be entitled to any rights as stockholders of the Corporation in
respect of such fractional interests. 

             6.5.   Adjustments for Subdivisions, Stock Dividends, Combinations, or
Consolidations of Common Stock. In the event the outstanding shares of Common
Stock shall be increased by way of stock issued as a dividend for no
consideration or subdivided (by stock split, or otherwise) into a greater number
of shares of Common Stock, the number of shares of Common Stock issuable upon
conversion of the Series H Preferred Stock then outstanding shall, concurrently
with the effectiveness of such increase or subdivision, be proportionately
increased and the number of shares constituting the Issuance Limit shall be
proportionally increased. In the event the outstanding shares of Common Stock
shall be combined or consolidated, by reclassification or otherwise, into a
lesser number of shares of Common Stock, the number of shares of Common Stock
issuable upon conversion of the Series H Preferred Stock then outstanding shall,
concurrently with the effectiveness of such combination or consolidation, be
proportionately decreased and the number of shares constituting the Issuance
Limit shall be proportionally decreased. 

             6.6.   Other Distributions. If for any reason, including without limitation a
merger or sale of assets transaction, the Corporation shall declare a
distribution payable in securities of the Corporation, or in securities of other
persons, evidences of indebtedness issued by the Corporation or other persons,
or assets (excluding cash dividends) then, in each such case for the purpose of
this Section 6.6, the holders of the Series H Preferred Stock shall be entitled
to a proportionate share of such distribution as though they were the holders of
the number of shares of Common Stock of the Corporation into which their shares
of Series H Preferred Stock would be convertible as of the record date fixed for
the determination of the holders of Common Stock of the Corporation entitled to
receive such distribution. 

             
6.7.    Reorganizations and Recapitalizations. If at any
time or from time to time there shall be a reorganization or recapitalization of
the Common Stock (other than a subdivision, combination or merger or sale of
assets transaction provided for in Section 6.5 or Section 6.6 above), then, as a
condition of such reorganization or recapitalization, provision shall be made so
that the holders of the Series H Preferred Stock shall thereafter be entitled to
receive upon conversion of the Series H Preferred Stock, the number of shares of
stock or other securities or property of the Corporation or otherwise to which a
holder of Common Stock deliverable upon conversion would have been entitled on
such reorganization or recapitalization. In any such case, appropriate
adjustment shall be made in the application of the provisions of this Section 6
with respect to the rights of the holders of the Series H Preferred Stock after
the reorganization or recapitalization to the end that the provisions of this
Section 6 (including adjustment to the number of shares of Common Stock
receivable upon conversion of the Series H Preferred Stock) shall be applicable
after that event in as nearly an equivalent manner as may be practicable. 

             
6.8.    Reservation of Shares. The Corporation agrees
that, so long as any share of Series H referred Stock shall remain outstanding,
the Corporation shall at all times reserve and keep available, free from
preemptive rights, out of its authorized capital stock, for the purpose of issue
upon conversion of the Series H Preferred Stock, the full number of shares of
Common Stock then issuable upon conversion of all outstanding shares of Series H
Preferred Stock. If the Common Stock shall be listed on any national securities
exchange, the Corporation at its expense shall include in a listing application
all of the shares of Common Stock reserved for issuance upon conversion of the
Series H Preferred Stock, (subject to issuance or notice of issuance to the
exchange) and will similarly apply for and use its best efforts to procure the
listing of any further Common Stock reserved for issuance upon conversion of the
Series H Preferred Stock, at any subsequent time as a result of adjustments in
the number of shares of Common Stock issuable upon conversion of the Series H
Preferred Stock. 

             
6.9.   Validity of Shares. The Corporation agrees that it
will from time to time take all such actions as may be requisite to assure that
all shares of Common Stock which may be issued upon conversion of any share of
the Series H Preferred Stock will, upon issuance, be legally and validly issued,
fully paid and non-assessable and free from all taxes, liens and charges with
respect to the issue thereof. 

             
6.10.   Taxes. The Corporation will pay all taxes and
other governmental charges that may be imposed in respect of the issue or
delivery (but not transfer) of shares of Common Stock upon conversion of the
Series H Preferred Stock.

             
6.11.   Abandonment of Action. If the Corporation shall
take a record of the holders of its Common Stock for the purpose of entitling
them to receive a dividend or distribution requiring an adjustment pursuant to
Section 6 and shall, thereafter and before the distribution to stockholders
thereof, legally abandon its plan to pay or deliver such dividend or
distribution, then thereafter no adjustment to the holders of Series H Preferred
Stock shall be required by reason of the taking of such record and any such
adjustment previously made in respect thereof shall be rescinded and annulled.

             
6.12.   Notice Provisions.

                  
6.12.1.    Whenever an adjustment is required pursuant to Section
6 hereof, the Corporation shall forthwith deliver to the holders of Series H
Preferred Stock, a certificate signed by an officer of the Corporation, setting
forth, in reasonable detail, the event requiring the adjustment, the method by
which such adjustment was calculated and the adjustments made. 

                  
6.12.2.    In case the Corporation shall propose (a) to pay any dividend payable in
stock of any class to the holders of H Junior Stock or to make any other
distribution to the holders of its Common Stock, (b) to offer to the holders of
its Common Stock rights to subscribe for or to purchase any Convertible
Securities, Common Stock or shares of stock of any class or any other
securities, rights or options, (c) to effect any reclassification of its Common
Stock (other than a reclassification involving only the subdivision or
combination of outstanding shares of Common Stock), (d) to effect any capital
reorganization, (e) to effect any consolidation, merger or sale, transfer or
other distribution of all or substantially all its property, assets or business,
or (f) to effect the liquidation, dissolution or winding-up of the Corporation,
then, in each such case, the Corporation shall give to each holder of Series H
Preferred Stock a notice of such proposed action, which shall specify the date
on which a record is to be taken for the purposes of such stock dividend,
distribution or rights, or the date on which such reclassification,
reorganization, consolidation, merger, sale, transfer, disposition, liquidation,
dissolution or winding-up is to take place and the date of participation therein
by the holders of Common Stock, if any such date is to be fixed, and shall also
set forth such facts with respect thereto as shall be reasonably necessary to
indicate the effect of such action on the Common Stock and number shares of
Common Stock issuable upon conversion of the Series H Preferred Stock after
giving effect to any adjustment which will be required as a result of such
action. Such notice shall be so given in the case of any action covered by (a)
or (b) above at least ten (10) days prior to the record date for determining
holders of the Common Stock for purposes of such action and, in the case of any
other such action, at least ten (10) days prior to the date of the taking of
such proposed action or the date of participation therein by the holders of
Common Stock, whichever shall be the earlier. 

        7.   No
Pre-emptive Rights. No holder of Series H Preferred Stock shall have any
pre-emptive or preferential right of subscription to any shares of stock of the
Corporation, or to options, warrants or other interests therein or therefor, or
to any obligations convertible into stock of the Corporation, issued or sold, or
any right of subscription to any thereof other than such, if any, as the Board
of Directors, in its discretion, from time to time may determine and at such
price or prices as the Board of Directors from time to time may fix pursuant to
the authority conferred by the Corporation’s Certificate of Incorporation.

        8.   Covenants.
In addition to any other rights provided by law, so long as any shares of Series
H Preferred Stock are outstanding, this Corporation shall not, without first
obtaining the affirmative vote or written consent of the holders of not less
than sixty-six and two-thirds percent (66-2/3%) of the Series H Preferred Stock:

             
(a)    Amend or repeal any provisions of the Corporation's
Certificate of Incorporation which action would adversely affect the rights,
preferences, or privileges of the Series H Preferred Stock; or

             
(b)    Alter or change the designations, powers, rights,
preferences or privileges, or the qualification, limitations or restrictions of
the Series H Preferred Stock; or

             
(c)    Increase the authorized number of shares of Series H
Preferred Stock or other preferred stock of the Corporation; or

             
(d)    Authorize, create, or issue any Series A Preferred Stock,
or any new class or series of stock or any other securities convertible into
equity securities of the Corporation having a preference over the Series H
Preferred Stock with respect to dividends, redemptions or upon liquidation or
dissolution of the Corporation; or

             
(e)    Reclassify the shares of Common Stock or any other H
Junior Stock into shares of any class or series of capital stock (i) ranking
either as to payment of dividends, distribution of assets or redemptions, prior
to or on parity with the Series H Preferred Stock, or (ii) which in any manner
adversely affects the holders of Series H Preferred Stock.

8.    The manner in which the foregoing Amendment of the
Certificate of Incorporation was authorized is as follows: The Board of
Directors of the Corporation authorized the Amendment under the authority vested
in said Board under the provisions of the Certificate of Incorporation and of
Section 502 of the Business Corporation Law.
