EXHIBIT 10.15.2

SECOND AMENDMENT TO THE
UCAR CARBON
COMPENSATION DEFERRAL PROGRAM

             The UCAR Carbon Compensation Deferral Program (as amended and
restated effective March 31, 2003) (“Plan”), is hereby amended as follows:

    1.       A new Section 1.3 is added to the Plan to read as follows:

“1.3      Notwithstanding any other provision of this Plan, it is intended that
all Post-2004 Deferrals under this Plan satisfy the provisions of Section 409A,
and this Plan shall be interpreted and administered, as necessary, to comply
with such provisions.”

    2.       Section 2.6 of the Plan is amended to add the following at the end
thereof:

  “Notwithstanding the foregoing, with respect to Post-2004 Deferrals only, the
foregoing definition of Change in Control is revised to read as follows:

  A “Change in Control of the Corporation” means the occurrence of any one of
the following events with respect to the Corporation:

  (i) any one person, or more than one person acting as a group, acquires
ownership of stock (as determined under Section 318(a) of the Internal Revenue
Code) of the Corporation that, together with stock held by such person or group,
constitutes more than 50 percent of the total fair market value or total voting
power of the stock of the Corporation; provided, however, that if any one person
or more than one person acting as a group, is considered to own more than 50
percent of the total fair market value or total voting power of the stock of the
Corporation, the acquisition of additional stock by the same person or persons
is not considered to cause a Change in Control of the Corporation. This
paragraph applies only when there is a transfer of stock of the Corporation (or
issuance of stock of the Corporation) and stock in the Corporation remains
outstanding after the transaction.

  (ii) any one person, or more than one person acting as a group, acquires (or
has acquired during the 12-month period ending on the date of the most recent
acquisition by such person or persons) ownership of stock (as determined under
Section 318(a) of the Internal Revenue Code) of the Corporation possessing 35
percent

  or more of the total voting power of the stock of the Corporation; provided,
however, that if any one person or more than one person acting as a group, is
considered to own 35 percent or more of the total voting power of the stock of
the Corporation, the acquisition of additional stock by the same person or
persons is not considered to cause a Change in Control of the Corporation.

  (iii) a majority of members of the Corporation’s Board of Directors (the
“Incumbent Directors”) is replaced during any 12-month period by directors whose
appointment or election is not endorsed by a majority of the Incumbent
Directors, provided that no other corporation is a majority shareholder of the
Corporation.

  (iv) any one person, or more than one person acting as a group, acquires (or
has acquired during the 12-month period ending on the date of the most recent
acquisition by such person or persons) assets from the Corporation that have a
total gross fair market value equal to or more than 40 percent of the total
gross fair market value of all of the assets of the Corporation immediately
prior to such acquisition(s); provided, however, that a transfer of assets by
the Corporation is not treated as a Change in Control if the assets are
transferred to (A) a shareholder of the Corporation (immediately before the
asset transfer) in exchange for or with respect to its stock; (B) an entity, 50
percent or more of the total value or voting power of which is owned, directly
or indirectly, by the Corporation; (C) a person, or more than one person acting
as a group, that owns, directly or indirectly, 50 percent of more of the total
value or voting power of all outstanding stock of the Corporation; or (D) an
entity, at least 50 percent of the total value or voting power of which is
owned, directly or indirectly, by a person described in the previous subsection
(C). For purposes of this paragraph, (1) gross fair market value means the value
of the assets of the Corporation, or the value of the assets being disposed of,
determined without regard to any liabilities associated with such assets, and
(2) a person’s status is determined immediately after the transfer of the
assets.

  For purposes of this definition:

  (a) a “person” shall be as such term is defined in Section 3(a)(9) of the
Securities Exchange Act of 1934 (the “Exchange Act”) and as used in Sections
13(d)(3) and 14(d)(2) of the Exchange Act.

  (b) persons will be considered to be acting as a group if they are owners of a
corporation that enters into a merger, consolidation, purchase or acquisition of
stock, or similar transaction with the Corporation. If a person, including an
entity, owns stock in both

2

  corporations that enter into a merger, consolidation, purchase or acquisition
of stock, or similar transaction, such shareholder is considered to be acting as
a group with other shareholders in the corporation prior to the transaction
giving rise to the Change in Control and not with respect to the ownership
interest in the other corporation. Persons will not be considered to be acting
as a group solely because they purchase or own stock of the Corporation at the
same time, or as a result of the same public offering.”

     3.       Section 2.13 is amended to add the following at the end thereof:

  “With respect to Post-2004 Deferrals only, “Disability” shall mean a
Participant’s inability to engage in any substantial gainful activity by reason
of any medically determinable physical or mental impairment which can be
expected to result in death or can be expected to last for a continuous period
of not less than 12 months; or (2) a Participant’s receiving, by reason of any
medically determinable physical or mental impairment which can be expected to
result in death or can be expected to last for a continuous period of not less
than 12 months, income replacement benefits for a period of not less than three
months under an accident and health plan covering employees of the participant’s
employer.”

     4.       Section 2.32 is amended to add the following at the end thereof:

  “With respect to Post-2004 Deferrals only, “Unforeseen Emergency” shall mean a
severe financial hardship to the Participant resulting from an illness or
accident of the Participant, the Participant’s spouse, or a dependent; loss of
the Participant’s property due to casualty; or other similar extraordinary and
unforeseeable circumstances arising as a result of events beyond the control of
the Participant.”

  5.        The following new Sections 2.35- 2.37 are added to the Plan to read
as follows:

  “2.35 “Initial Deferral Date” shall mean the date a Participant has made an
election to defer amounts to be earned in the following year (or for new
Participants, for the remainder of that year), and for Make-up Contributions and
Additional Matching Contributions under the Plan, Initial Deferral Date shall
mean the December 31st of the year preceding the year in which such
Contributions shall be allocated.

  2.36 “Post-2004 Deferrals” shall mean any and all deferrals and contributions
that are earned by, vested, or allocated to a Participant in the Plan after
December 31, 2004.

  2.37  “Section 409A” shall mean Section 409A of the Code and any regulations
and rulings issued thereunder.
