the request of the Collateral Agent, such promissory note, instrument or Chattel
Paper shall be immediately delivered to the Collateral Agent, duly indorsed in a
manner reasonably satisfactory to the Collateral Agent, to be held as Collateral
pursuant to this Agreement.

            4.2 MAINTENANCE OF INSURANCE. Such Grantor shall maintain insurance
policies in accordance with the requirements of Section 6.02 of the Credit

the Collateral Agent, and at the sole expense of such Grantor, such Grantor
shall promptly and duly execute and deliver such further instruments and
documents and take such further action as the Collateral Agent may reasonably
request for the purpose of obtaining or preserving the full benefits of this
Agreement and of the rights and powers herein granted, including, without
limitation, the filing of any financing or continuation statements under the

                                                                              11

Uniform Commercial Code in effect in any jurisdiction with respect to the
security interests created hereby.

            4.4 CHANGES IN LOCATIONS, NAME, ETC. Such Grantor shall not, except
(x) upon prior written notice to the Collateral Agent and delivery to the
Collateral Agent of a written supplement to the Perfection Certificate (duly
executed by a Financial Officer and the chief legal officer of each of UCAR and
the Borrower on behalf of UCAR and the Borrower) showing the additional location
or locations at which Collateral shall be maintained, and (y) if filings under
the UCC or otherwise have been made which maintain in favor of the Collateral
Agent a valid, legal and perfected security interest in such Collateral subject
to no liens, other than Permitted Liens,

            (a) permit any of the Inventory or Equipment owned by it to be kept
      at a location other than those listed in the Perfection Certificate,
      except for Inventory and Equipment in transit between locations described
      in this paragraph (a) or transferred to a foreign Subsidiary in a
      transaction permitted by the Credit Agreement;

            (b) change the location of its chief executive office and chief
      place of business from that specified in Perfection Certificate; or

            (c) change its (i) corporate name or any trade name used to identify
      it in its conduct of business or in the ownership of its properties, (ii)
      identity or (iii) corporate structure to such an extent that any financing
      statement filed in favor of the Collateral Agent in connection with this
      Agreement would become seriously misleading.

            4.5 FURTHER IDENTIFICATION OF COLLATERAL. Such Grantor shall furnish
to the Collateral Agent from time to time statements and schedules further
identifying and describing the Collateral owned by it and such other reports in
connection with such Collateral as the Collateral Agent may reasonably request,

      Permitted Liens) on any material portion of the Collateral; and

            (b) of the occurrence of any other event which could reasonably be
      expected to have a material adverse effect on the security interests
      created hereby or on the aggregate value of (i) the Collateral owned by it
      and (ii) all other Collateral (as such term is defined in the other

                                                                              12

      whole.

            4.8 COLLATERAL AGENT'S LIABILITIES AND EXPENSES; INDEMNIFICATION.
(a) Notwithstanding anything to the contrary provided herein, the Collateral
Agent assumes no liabilities with respect to any claims regarding each Grantor's
ownership (or purported ownership) of, or rights or obligations (or purported
rights or obligations) arising from, the Collateral or any use (or actual or
alleged misuse) whether arising out of any past, current or future event,
circumstance, act or omission or otherwise, or any claim, suit, loss, damage,
expense or liability of any kind or nature arising out of or in connection with
the Collateral or the production, marketing, delivery, sale or provision of
goods or services under or in connection with any of the Collateral. All of such
liabilities shall, as between the Collateral Agent and the Grantors, be borne
exclusively by the Grantors.

            (b) Each Grantor hereby agrees to pay all expenses of the Collateral
Agent and to indemnify the Collateral Agent with respect to any and all losses,
claims, damages, liabilities and related expenses in respect of this Agreement
or the Collateral in each case to the extent the Borrower is required to do so
pursuant to Section 10.03 of the Credit Agreement.

            (c) Any amounts payable by a Grantor as provided hereunder shall be
additional Obligations of it secured hereby and by the other Security Documents.
Without prejudice to the survival of any other agreements contained herein, all
indemnification and reimbursement obligations contained herein shall survive the
payment in full of the principal and interest under the Credit Agreement, the
expiration of the Letters of Credit and the termination of the Commitments or
this Agreement.

            4.9 USE AND DISPOSITION OF COLLATERAL. A Grantor shall not (i) make
or permit to be made an assignment, pledge or hypothecation of the Collateral
owned by it, and shall grant no other security interest in such Collateral
(other than pursuant hereto or except for any Permitted Liens) or (ii) make or
permit to be made any transfer of such Collateral, and shall remain at all times
in possession thereof other than transfers to the Collateral Agent pursuant to
the provisions hereof; notwithstanding the foregoing, such Grantor may use and
dispose of such Collateral in any lawful manner not in violation of the
provisions of this Agreement, the Credit Agreement or any other Loan Document to
which it is a party, unless the Collateral Agent shall, after an Event of
Default shall have occurred and during the continuance thereof, notify such
Grantor not to sell, convey, lease, assign, transfer or otherwise dispose of any
such Collateral other than Inventory in the ordinary course of business,
Permitted Foreign Transfers and other than any other transfers between the

Borrower or a Wholly Owned Subsidiary that is a Grantor and a Borrower or a
Wholly Owned Subsidiary that is a Grantor.

            5.  PROVISIONS RELATING TO ACCOUNTS.

            5.1 GRANTORS REMAIN LIABLE UNDER ACCOUNTS. Anything herein to the
contrary notwithstanding, a Grantor shall remain liable under each of the
Accounts to observe and perform all the conditions and obligations to be
observed and performed by it thereunder, all in accordance with the terms of any
agreement giving rise to each such Account. No Secured Party shall have any
obligation or liability under any Account (or any agreement giving rise thereto)
by reason of or arising out of this Agreement or the receipt by the Collateral
Agent or any Secured Party of any payment relating to such Account pursuant
hereto, nor shall any Secured Party be obligated in any manner to perform any of
the obligations of a Grantor under or pursuant to any Account (or any agreement
giving rise thereto), to make any payment, to make any inquiry as to the nature
or the sufficiency of any payment received by it or as to the sufficiency of any
performance by any party under any Account (or any agreement giving rise
thereto), to present or file any claim, to take any action to enforce any
performance or to collect the payment of any amounts which may have been
assigned to it or to which it may be entitled at any time or times.

            5.2 ANALYSIS OF ACCOUNTS. The Collateral Agent shall have the right
upon the occurrence and during the continuance of an Event of Default to make
test verifications of the Accounts in any manner and through any medium that it
considers reasonably advisable, and each Grantor shall furnish all such
assistance and information as the Collateral Agent may reasonably require in
connection with such test verifications. At any time and from time to time upon
the occurrence and during the continuance of an Event of Default, upon the
Collateral Agent's reasonable request and at the expense of each Grantor, each
Grantor shall cause independent public accountants or others reasonably
satisfactory to the Collateral Agent to furnish to the Collateral Agent reports
showing reconciliations, aging and test verifications of, and trial balances
for, the Accounts. Upon the occurrence and during the continuance of an Event of
Default, the Collateral Agent in its own name or in the name of others may
communicate with account debtors on the Accounts to verify with them to the
Collateral Agent's reasonable satisfaction the existence, amount and terms of
any Accounts.

            5.3 COLLECTIONS ON ACCOUNTS. (a) The Collateral Agent hereby
authorizes each Grantor to collect the Accounts, and the Collateral Agent may
curtail or terminate said authority at any time after the occurrence and during
the continuance of an Event of Default. If required by the Collateral Agent at
any time after the occurrence and during the continuance of an Event of Default,
any payments of Accounts, when collected by a Grantor during the continuance of

<PAGE>

                                                                              14

such an Event of Default, (i) shall be forthwith (and, in any event, within two
Business Days) deposited by such Grantor in the exact form received, duly
indorsed by such Grantor to the Collateral Agent if required, in a Collateral
Account maintained under the sole dominion and control of and on terms and
conditions reasonably satisfactory to the Collateral Agent, subject to
withdrawal by the Collateral Agent as provided in Section 7.3, and (ii) until so
turned over, shall be held by such Grantor in trust for the Secured Parties,
segregated from other funds of such Grantor.

            (b) At the Collateral Agent's reasonable request after the
occurrence and during the continuance of an Event of Default, each Grantor shall
deliver to the Collateral Agent all original and other documents evidencing, and
relating to, the agreements and transactions which gave rise to the Accounts,
including, without limitation, all original orders, invoices and shipping
receipts.

            5.4 REPRESENTATIONS AND WARRANTIES. (a) As of the date hereof, the
place where each Grantor keeps its records concerning the Accounts is at the
location listed in Section 2(b) of the Perfection Certificate.

            (b) As of the date hereof, the amounts owing with respect to
Accounts of obligors which are Governmental Authorities do not constitute more
than 15% of the average aggregate amount owing on the Accounts owing to UCAR and
any Subsidiaries, taken as a whole, during the most recently ended period of
twelve consecutive calendar months.

            5.5 COVENANTS. (a) The amount represented by each Grantor to the
Secured Parties from time to time as owing by each account debtor or by all
account debtors in respect of the Accounts shall at such time be in all material
respects the correct amount actually owing by such account debtor or debtors
thereunder.

            (b) Upon the occurrence and during the continuance of an Event of
Default, a Grantor shall not grant any extension of the time of payment of any
of the Accounts Receivable, compromise, compound or settle the same for less
than the full amount thereof, release, wholly or partly, any person liable for
the payment thereof, or allow any credit or discount whatsoever thereon other
than extensions, credits, discounts, compromises or settlements granted or made
in the ordinary course of business if the Collateral Agent shall have instructed
the Grantors not to grant or make any such extension, credit, discount,
compromise, or settlement under any circumstances during the continuance of such
Event of Default.

            (c) Unless a Grantor shall deliver prior written notice, identifying
the change of location for its books and records, such Grantor shall not remove
its books and records from the location specified in Section 5.4(a).

            6.  PROVISIONS RELATING TO CONTRACTS.

            6.1 GRANTORS REMAIN LIABLE UNDER CONTRACTS. Anything herein to the
contrary notwithstanding, each Grantor shall remain liable under each Contract
to observe and perform all the conditions and obligations to be observed and
performed by it thereunder, all in accordance with and pursuant to the terms and
provisions of such Contract. No Secured Party shall have any obligation or
liability under any Contract by reason of or arising out of this Agreement or
the receipt by any such Secured Party of any payment relating to such Contract
pursuant hereto, nor shall any Secured Party be obligated in any manner to
perform any of the obligations of a Grantor under or pursuant to any Contract,
to make any payment, to make any inquiry as to the nature or the sufficiency of
any payment received by it or as to the sufficiency of any performance by any
party under any Contract, to present or file any claim, to take any action to
enforce any performance or to collect the payment of any amounts which may have
been assigned to it or to which it may be entitled at any time or times.

            6.2 COMMUNICATION WITH CONTRACTING PARTIES. Upon the occurrence and
during the continuance of an Event of Default, the Collateral Agent in its own
name or in the name of others may communicate with parties to the Contracts to
verify with them to the Collateral Agent's satisfaction the existence, amount
and terms of any Contracts.

            7.  REMEDIES.

            7.1 NOTICE TO ACCOUNT DEBTORS AND CONTRACT PARTIES. Upon the request
of the Collateral Agent at any time after the occurrence and during the
continuance of an Event of Default, a Grantor shall notify account debtors on
the Accounts and parties to the Contracts that the Accounts and the Contracts
have been assigned to the Collateral Agent for the ratable benefit of the
Secured Parties and that payments in respect thereof during the continuance of
such an Event of Default shall be made directly to the Collateral Agent.

            7.2 PROCEEDS TO BE TURNED OVER TO COLLATERAL AGENT. In addition to
the rights of the Collateral Agent and the Secured Parties specified in Section
5.3 with respect to payments of Accounts, if an Event of Default shall occur and
be continuing, all Proceeds received by a Grantor consisting of cash, checks and
other near-cash items shall upon the Collateral Agent's request be held by such
Grantor in trust for the Secured Parties, segregated from other funds of such
Grantor, and shall, upon the Collateral Agent's request (it being understood

<PAGE>

                                                                              16

that the exercise of remedies by the Secured Parties in connection with an Event
of Default under Sections VIII(h) and VIII(i) of the Credit Agreement shall be
deemed to constitute a request by the Collateral Agent for the purposes of this
sentence) forthwith upon receipt by such Grantor, be turned over to the
Collateral Agent in the exact form received by such Grantor (duly indorsed by
such Grantor to the Collateral Agent, if required) and held by the Collateral
Agent in a Collateral Account maintained under the sole dominion and control of
the Collateral Agent and on terms and conditions reasonably satisfactory to the
Collateral Agent. All Proceeds while held by the Collateral Agent in a
Collateral Account (or by such Grantor in trust for the Collateral Agent and the
Secured Parties) shall subject to Section 7.3 continue to be held as collateral
security for all the Obligations and shall not constitute payment thereof until
applied as provided in Section 7.3.

            7.3 APPLICATION OF PROCEEDS. If an Event of Default shall have
occurred and be continuing, and the Collateral Agent shall have requested a
Grantor to take any action set forth in Section 5.3(a) or 7.2 or the Collateral
Agent shall have taken any action pursuant to Section 7.4, the Collateral Agent
shall apply the proceeds as follows:

            FIRST, to the payment of all costs and expenses incurred by the
      Administrative Agent or the Collateral Agent (in its capacity as such
      hereunder or under any other Loan Document) in connection with such
      collection or sale or otherwise in connection with this Agreement or any
      of the Obligations, including all reasonable court costs and the
      reasonable fees and expenses of its agents and legal counsel, the
      repayment of all advances made by the Collateral Agent hereunder or under
      any other Loan Document on behalf of any Grantor and any other costs or
      expenses incurred in connection with the exercise of any right or remedy
      hereunder or under any other Loan Document;

            SECOND, to the payment of all amounts of the Obligations owed to the
      Secured Parties in respect of Loans made by them and outstanding and
      amounts owing in respect of any LC Disbursement or Letter of Credit or
      under any Interest/Exchange Rate Protection Agreement, pro rata as among
      the Secured Parties in accordance with the amount of such Obligations owed
      to them;

            THIRD, to the payment and discharge in full of the Obligations
      (other than those referred to above), pro rata as among the Secured
      Parties in accordance with the amount of such Obligations owed to them;
      and

            FOURTH, after payment in full of all Obligations, to the applicable
      Grantor, or its successors or assigns, or to whomsoever may be lawfully

<PAGE>

                                                                              17

      entitled to receive the same or as a court of competent jurisdiction may
      direct, any Collateral then remaining.

            7.4 CODE REMEDIES. If an Event of Default shall have occurred and be
continuing, the Collateral Agent, on behalf of the Secured Parties may exercise,
in addition to all other rights and remedies granted to them in this Agreement
and in any other instrument or agreement securing, evidencing or relating to the
Obligations, all rights and remedies of a secured party under the Code. Without
limiting the generality of the foregoing, the Collateral Agent, without demand
of performance or other demand, presentment, protest, advertisement or notice of
any kind (except any notice required by law referred to below) to or upon a
Grantor or any other person (all and each of which demands, defenses,
advertisements and notices are hereby waived), may in such circumstances
forthwith collect, receive, appropriate and realize upon the Collateral, or any
part thereof, and/or may forthwith sell, lease, assign, give option or options
to purchase, or otherwise dispose of and deliver the Collateral or any part
thereof (or contract to do any of the foregoing), in one or more parcels at
public or private sale or sales, at any exchange, broker's board or office of
any Secured Party or elsewhere upon such terms and conditions as it may deem
advisable and at such prices as it may deem best, for cash or on credit or for
future delivery without assumption of any credit risk. Any Secured Party shall
have the right upon any such public sale or sales, and, to the extent permitted
by law, upon any such private sale or sales, to purchase the whole or any part
of the Collateral so sold, free of (to the extent permitted by law) any right or
equity of redemption in a Grantor, which right or equity is hereby, to the
extent permitted by law, waived or released. Each Grantor further agrees, at the
Collateral Agent's request, to assemble the Collateral and make it available to
the Collateral Agent at places which the Collateral Agent shall reasonably
select, whether at such Grantor's premises or elsewhere. The Collateral Agent
shall apply the net proceeds of any such collection, recovery, receipt,
appropriation, realization or sale, after deducting all reasonable costs and
expenses incurred therein or incidental to the care or safekeeping of any of
such Collateral or reasonably relating to such Collateral or the rights of the
Collateral Agent and the Secured Parties hereunder, including, without
limitation, reasonable attorneys' fees and disbursements, to the payment in
whole or in part of the Obligations, in accordance with Section 7.3, and only
after such application and after the payment by the Collateral Agent of any
other amount required by any provision of law, including, without limitation,
Section 9-504(1)(c) of the Code, need the Collateral Agent account for the
surplus, if any, to such Grantor. If any notice of a proposed sale or other
disposition of such Collateral shall be required by law, such notice shall be in
writing and deemed reasonable and proper if given at least 10 days before such
sale or other disposition.

            The Collateral Agent shall have absolute discretion as to the time
of application of any such proceeds, moneys or balances in accordance with this
Agreement. Upon any sale of the Collateral by the Collateral Agent (including

<PAGE>

                                                                              18

pursuant to a power of sale granted by statute or under a judicial proceeding),
the receipt of the Collateral Agent or of the officer making the sale shall be a
sufficient discharge to the purchaser or purchasers of the Collateral so sold
and such purchaser or purchasers shall not be obligated to see to the
application of any part of the purchase money paid over to the Collateral Agent
or such officer or be answerable in any way for the misapplication thereof.

            7.5 WAIVER; DEFICIENCY. Each Grantor waives and agrees not to assert
any rights or privileges it may acquire under Section 9-112 of the Code. Each
Grantor shall remain liable for any deficiency if the proceeds of any sale or
other disposition of the Collateral are insufficient to pay (i) in the case of
each of UCAR and Global, its Obligations or those of the Borrower (including as
guarantor) and (ii) in the case of each other Grantor, the Obligations and the
reasonable fees and disbursements of any attorneys employed by any Secured Party
to collect such deficiency.

            8.  COLLATERAL AGENT'S APPOINTMENT AS ATTORNEY-IN-FACT; COLLATERAL
AGENT'S PERFORMANCE OF GRANTORS' OBLIGATIONS.

            8.1 POWERS. Each Grantor hereby irrevocably constitutes and appoints
the Collateral Agent and any officer or agent thereof, with full power of
substitution, during the continuance of an Event of Default, as its true and
lawful attorney-in-fact, with full irrevocable power and authority in the place
and stead of such Grantor and in the name of such Grantor or in its own name
from time to time in the Collateral Agent's discretion, for the purpose of
carrying out the terms of this Agreement, to take any and all appropriate action
and to execute any and all documents and instruments which may be necessary or
desirable to accomplish the purposes of this Agreement, and, without limiting
the generality of the foregoing, such Grantor hereby gives the Collateral Agent
the power and right, on behalf of such Grantor, without notice to or assent by
such Grantor, to do the following upon the occurrence and during the continuance
of an Event of Default:

            (a) in the name of such Grantor or its own name, or otherwise, to
      take possession of and indorse and collect any checks, drafts, notes,
      acceptances or other instruments for the payment of moneys due under any
      Account, Instrument, General Intangible or Contract or with respect to any
      other Collateral and to file any claim or to take any other action or
      proceeding in any court of law or equity or otherwise deemed appropriate
      by the Collateral Agent for the purpose of collecting any and all such
      moneys due under any Account, Instrument, General Intangible or Contract
      or with respect to any other Collateral whenever payable;

<PAGE>

                                                                              19

            (b) to pay or discharge taxes and Liens levied or placed on or
      threatened against the Collateral (other than Permitted Liens), to effect
      any repairs or any insurance called for by the terms of this Agreement and
      to pay all or any part of the premiums therefor and the costs thereof,

            (c) to execute, in connection with any sale provided for in Section
      7.4 hereof, any endorsements, assignments or other instruments of
      conveyance or transfer with respect to the Collateral; and

            (d)(i) to direct any party liable for any payment under any of the
      Collateral to make payment of any and all moneys due or to become due
      thereunder directly to the Collateral Agent or as the Collateral Agent
      shall direct; (ii) to ask or demand for, collect, receive payment of and
      receipt for, any and all moneys, claims and other amounts due or to become
      due at any time in respect of or arising out of any Collateral; (iii) to
      sign and indorse any invoices, freight or express bills, bills of lading,
      storage or warehouse receipts, drafts against debtors, assignments,
      verifications, notices and other documents in connection with any of the
      Collateral; (iv) to commence and prosecute any suits, actions or
      proceedings at law or in equity in any court of competent jurisdiction to
      collect the Collateral or any thereof and to enforce any other right in
      respect of any Collateral; (v) to defend any suit, action or proceeding
      brought against any Grantor with respect to any Collateral; (vi) to
      settle, compromise or adjust any such suit, action or proceeding and, in
      connection therewith, to give such discharges or releases as the
      Collateral Agent may deem appropriate; and (vii) generally, to use, sell,
      transfer, pledge and make any agreement with respect to or otherwise deal
      with any of the Collateral as fully and completely as though the
      Collateral Agent were the absolute owner thereof for all purposes, and to
      do, at the Collateral Agent's option and at the expense of such Grantor,
      at any time, or from time to time, all acts and things which the
      Collateral Agent reasonably deems necessary to protect, preserve or
      realize upon such Collateral and the Collateral Agent's and the Secured
      Parties' security interests therein and to effect the intent of this
      Agreement, all as fully and effectively as such Grantor might do.

            8.2 PERFORMANCE BY COLLATERAL AGENT OF GRANTOR'S OBLIGATIONS. If any
Grantor fails to perform or comply with any of its agreements contained herein,
the Collateral Agent, at its option, but without any obligation so to do, may
perform or comply, or otherwise cause performance or compliance, with such
agreement.

            8.3 GRANTOR'S REIMBURSEMENT OBLIGATION. The expenses of the
Collateral Agent reasonably incurred in connection with actions undertaken as
provided in this Section 8, together with interest thereon at a rate per annum

<PAGE>

                                                                              19

equal to the default rate of interest set forth in Section 2.12 of the Credit
Agreement, from the date payment is demanded by the Collateral Agent to the date
reimbursed by a Grantor, shall be payable by the Borrower to the Collateral
Agent on demand.

            8.4 RATIFICATION; POWER COUPLED WITH AN INTEREST. Each Grantor
hereby ratifies all that said attorneys shall lawfully do or cause to be done by
virtue hereof. All powers, authorizations and agencies contained in this
Agreement are coupled with an interest and are irrevocable until this Agreement
is terminated and the security interests created hereby are released.

            9. DUTY OF COLLATERAL AGENT. The Collateral Agent's sole duty with
respect to the custody, safekeeping and physical preservation of the Collateral
in its possession, under Section 9-207 of the Code or otherwise, shall be to
deal with it in the same manner as the Collateral Agent deals with similar
property for its own account. No Secured Party nor any of its respective
directors, officers, employees or agents shall be liable for failure to demand,
collect or realize upon any of the Collateral or for any delay in doing so or
shall be under any obligation to sell or otherwise dispose of any Collateral
upon the request of a Grantor or any other person or to take any other action
whatsoever with regard to the Collateral or any part thereof. The powers
conferred on the Secured Parties hereunder are solely to protect the Secured
Parties' interests in the Collateral and shall not impose any duty upon any
Secured Party to exercise any such powers. The Secured Parties shall be
accountable only for amounts that they actually receive as a result of the
exercise of such powers, and neither they nor any of their officers, directors,
employees or agents shall be responsible to any Grantor for any act or failure
to act hereunder, except for their own gross negligence or willful misconduct.

            10. EXECUTION OF FINANCING STATEMENTS. Pursuant to Section 9-402 of
the Code, each Grantor authorizes the Collateral Agent to file financing
statements with respect to the Collateral without the signature of such Grantor
in such form and in such filing offices as the Collateral Agent reasonably
determines appropriate to perfect the security interests of the Collateral Agent
under this Agreement. A carbon, photographic or other reproduction of this
Agreement shall be sufficient as a financing statement for filing in any

INTO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS, AS APPLICABLE, BY, AMONG OTHER
THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 15.

            16. JURISDICTION; CONSENT TO SERVICE OF PROCESS. (a) Each Grantor
hereby irrevocably and unconditionally submits, for itself and its property, to
the nonexclusive jurisdiction of any New York State court or Federal court of
the United States of America sitting in New York City, and any appellate court
from any thereof, in any action or proceeding arising out of or relating to this
Agreement or the other Loan Documents, or for recognition or enforcement of any
judgment, and each of the parties hereto hereby irrevocably and unconditionally
agrees that all claims in respect of any such action or proceeding may be heard
and determined in such New York State or, to the extent permitted by law, in
such Federal court. Each of the parties hereto agrees that a final judgment in
any such action or proceeding shall be conclusive and may be enforced in other
jurisdictions by suit on the judgment or in any other manner provided by law.
Nothing in this Agreement shall affect any right that any Loan Party or any
Secured Party may otherwise have to bring any action or proceeding relating to
this Agreement or the other Loan Documents against any Grantor or any Secured

            (b) Each Grantor and each Secured Party hereby irrevocably and

any suit, action or proceeding arising out of or relating to this Agreement or
the other Loan Documents in any New York State or Federal court. Each of the
parties hereto hereby irrevocably waives, to the fullest extent permitted by
law, the defense of an inconvenient forum to the maintenance of such action or
proceeding in any such court.

            (c) Each party to this Agreement irrevocably consents to service of
process in the manner provided for notices in Section 12. Nothing in this
Agreement will affect the right of any party to this Agreement to serve process
in any other manner permitted by law.

            17. RELEASE. (a) This Agreement and the security interest created
hereunder shall terminate when all Obligations have been fully and indefeasibly
paid and when the Secured Parties have no further Commitments under the Credit
Agreement and no Letters of Credit are outstanding, at which time the Collateral
Agent shall execute and deliver to each Grantor, or to such person or persons as
such Grantor shall reasonably designate, all Uniform Commercial Code termination
statements and similar documents prepared by such Grantor at its expense which
such Grantor shall reasonably request to evidence such termination. Any

                                                                              23

execution and delivery of termination statements or documents pursuant to this
Section 17(a) shall be without recourse to or warranty by the Collateral Agent.

            (b) A Subsidiary Grantor shall automatically be released from its
obligations hereunder and the Security Interest in the Collateral of such
Subsidiary Grantor shall be automatically released in the event that all the
Capital Stock of such Subsidiary Grantor shall be sold, transferred or otherwise
disposed of to a person that is not an Affiliate of UCAR in a transaction
permitted pursuant to Section 7.05 of the Credit Agreement. Any Collateral
granted hereunder shall be released (automatically and without further action on
the part of the Collateral Agent) upon the sale, transfer or other disposition
of such Collateral to a transferee who is not a "Grantor" hereunder, to the
extent that such sale, transfer or other disposition is permitted under the
Credit Agreement.

            18. SEVERABILITY. Any provision of this Agreement which is
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction. The parties hereunder
shall endeavor in good-faith negotiations to replace the invalid, illegal or
unenforceable provisions with valid provisions, the economic effect of which
comes as close as possible to that of the invalid, illegal or unenforceable
provisions.

            19.  AMENDMENTS IN WRITING; NO WAIVER; CUMULATIVE REMEDIES.

            19.1 AMENDMENTS IN WRITING. None of the terms or provisions of this
Agreement may be waived, amended, supplemented or otherwise modified except by a
written instrument executed by the Grantors and the Collateral Agent; PROVIDED
that any provision of this Agreement may be waived by the Required Lenders
pursuant to a letter or agreement executed by the Collateral Agent or by
telecopy transmission from the Collateral Agent.

            19.2 NO WAIVER BY COURSE OF CONDUCT. No Secured Party shall by any
act (except by a written instrument pursuant to Section 19.1 hereof) or delay be
deemed to have waived any right or remedy hereunder or to have acquiesced in any
Default or Event of Default or in any breach of any of the terms and conditions
hereof. No failure to exercise, nor any delay in exercising, on the part of any
Secured Party, any right, power or privilege hereunder shall operate as a waiver
thereof. No single or partial exercise of any right, power or privilege
hereunder shall preclude any other or further exercise thereof or the exercise
of any other right, power or privilege. A waiver by any Secured Party of any

                                                                              24

right or remedy hereunder on any one occasion shall not be construed as a bar to
any right or remedy which such Secured Party would otherwise have on any future
occasion.

            20. REMEDIES CUMULATIVE. The rights and remedies herein provided are
cumulative, may be exercised singly or concurrently and are not exclusive of any
other rights or remedies provided by law.

            21. SECTION HEADINGS. The section and Section headings used in this
Agreement are for convenience of reference only and are not to affect the
construction hereof or be taken into consideration in the interpretation hereof.

            22. SUCCESSORS AND ASSIGNS. This Agreement shall be binding upon the
successors and assigns of each Grantor and shall inure to the benefit of each
Grantor and the Secured Parties and their successors and assigns; PROVIDED that
this Agreement may not be assigned by any Grantor without the prior written
consent of the Collateral Agent.

            23.  GOVERNING LAW.  THIS AGREEMENT SHALL BE GOVERNED BY, AND
CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

            24.  COUNTERPARTS.  This Agreement may be executed in two or more
counterparts, each of which shall constitute an original but all of which when
taken together shall constitute but one contract.

            25. ADDITIONAL GRANTORS. Pursuant to Section 6.11 of the Credit
Agreement, each Domestic Subsidiary that was not in existence or not a Domestic
Subsidiary on the date thereof is required to enter into this Agreement as a
Grantor upon becoming a Domestic Subsidiary. Upon execution and delivery, after
the date hereof, by the Collateral Agent and such Domestic Subsidiary of an
instrument in the form of Exhibit A-1, such Domestic Subsidiary shall become a
Grantor hereunder with the same force and effect as if originally named as a
Grantor hereunder. The execution and delivery of any such instrument shall not
require the consent of any Grantor hereunder. The rights and obligations of each
Grantor hereunder shall remain in full force and effect notwithstanding the
addition of any new Grantor as a party to this Agreement.

                                                              SECURITY AGREEMENT

                        SUPPLEMENT NO. dated as of [], to the Security Agreement
                  dated as of February 22, 2000 (the "SECURITY AGREEMENT"), made
                  by UCAR INTERNATIONAL INC., a Delaware corporation ("UCAR"),
                  UCAR GLOBAL ENTERPRISES INC., a Delaware corporation
                  ("GLOBAL"), UCAR FINANCE INC., a Delaware corporation (the
                  "BORROWER"), and the subsidiaries of UCAR from time to time
                  party thereto (the "SUBSIDIARY GRANTORS", and together with
                  UCAR and the Borrower, the "GRANTORS") in favor of MORGAN
                  GUARANTY TRUST COMPANY OF NEW YORK as collateral agent for the
                  Secured Parties (such term and each other capitalized term
                  used but not defined herein having the meaning given it in
                  Article I of the Credit Agreement).

            A. Reference is made to the Credit Agreement dated as of February
22, 2000 (as the same may be amended, supplemented or otherwise modified from
time to time, the "CREDIT AGREEMENT") among UCAR, Global, the Borrower, the LC
Subsidiaries from time to time party thereto, the Lenders from time to time
party thereto and Morgan Guaranty Trust Company of New York, as Administrative

            B. The Grantors have entered into the Security Agreement in order to
induce the Lenders to make Loans and the Issuing Bank to issue Letters of Credit
pursuant to, and upon the terms and subject to the conditions specified in, the
Credit Agreement. Pursuant to Section 6.11 of the Credit Agreement, each
Domestic Subsidiary that was not in existence or not a Domestic Subsidiary on
the date thereof is required to enter into the Security Agreement as a Grantor
upon becoming a Domestic Subsidiary. Section 25 of the Security Agreement
provides that additional Domestic Subsidiaries may become Grantors under the
Security Agreement by execution and delivery of an instrument in the form of
this Supplement. The undersigned (the "NEW GRANTOR") is a U.S. Subsidiary and is
executing this Supplement in accordance with the requirements of the Credit
Agreement to become a Grantor under the Security Agreement in order to induce
the Lenders to make additional Loans and the Issuing Bank to issue additional
Letters of Credit and as consideration for Loans previously made and Letters of
Credit previously issued.

            Accordingly, the Collateral Agent and the New Grantor agree as
follows:

                                                                              2

            SECTION 1. In accordance with Section 25 of the Security Agreement,
the New Grantor by its signature below becomes a Grantor under the Security
Agreement with the same force and effect as if originally named therein as a
Grantor and the New Grantor hereby agrees to all the terms and provisions of the
Security Agreement applicable to it as a Grantor thereunder. Each reference to a
"Grantor" in the Security Agreement shall be deemed to include the New Grantor.
The Security Agreement is hereby incorporated herein by reference.

            SECTION 2. The New Grantor represents and warrants to the Secured
Parties that this Supplement has been duly authorized, executed and delivered by
it and constitutes its legal, valid and binding obligation, enforceable against
it in accordance with its terms, subject to the effects of applicable
bankruptcy, insolvency or similar laws effecting creditors' rights generally and
equitable principles of general applicability.

            SECTION 3. This Supplement may be executed in two or more
counterparts, each of which shall constitute an original, but all of which, when
taken together, shall constitute but one instrument. This Supplement shall
become effective when the Collateral Agent shall have received counterparts of
this Supplement that, when taken together, bear the signatures of the New
Grantor and the Collateral Agent.

            SECTION 4. Except as expressly supplemented hereby, the Security
Agreement shall remain in full force and effect.

            SECTION 5. THIS SUPPLEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN
ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

            SECTION 6. In case any one or more of the provisions contained in
this Supplement should be held invalid, illegal or unenforceable in any respect,
neither party hereto shall be required to comply with such provision for so long
as such provision is held to be invalid, illegal or unenforceable, but the
validity, legality and enforceability of the remaining provisions contained
herein and in the Security Agreement shall not in any way be affected or
impaired. The parties hereto shall endeavor in good-faith negotiations to
replace the invalid, illegal or unenforceable provisions with valid provisions
the economic effect of which comes as close as possible to that of the invalid,
illegal or unenforceable provisions.

            SECTION 7. All communications and notices hereunder shall be in
writing and given as provided in the Credit Agreement. All communications and
notices hereunder to the New Grantor shall be given to it at the address set
forth under its signature, with a copy to the Borrower.

         agreed to make Loans and to issue Letters of Credit pursuant to, and
         upon the terms and subject to the conditions specified in, the Credit

         (including, without limitation, all monetary obligations of the
         Intercompany Borrowers under the Intercompany Notes and Intercompany
         Borrower Agreements, but only for so long as the Intercompany Notes and
         the rights of the Borrower under the Intercompany Borrower Agreements
         are pledged to the Collateral Agent under one or more Pledge Agreements
         as security for the Obligations), (b) the due and punctual performance
         of all covenants, agreements, obligations and liabilities of the Loan
         Parties under or pursuant to the Credit Agreement and the other Loan
         Documents, (c) unless otherwise agreed upon in writing by the
         applicable Lender party thereto, the due and punctual payment and
         performance of all obligations of the Borrower and the Subsidiaries,
         monetary or otherwise, under each Interest/Exchange Rate Protection
         Agreement entered into with any counterparty that (i) was a Lender (or
         an Affiliate thereof) at the time such Interest/Exchange Rate
         Protection Agreement was entered into or (ii) (A) was a "Lender" (or an
         Affiliate thereof) as defined in the Existing Credit Agreements at the
         time such Interest/Exchange Rate Protection Agreement was entered into
         and (B) was one of the initial lenders under the Credit Agreement (or
         an Affiliate thereof) and (d) all obligations of UCAR and Global under
         the Guarantee Agreements (all of the foregoing obligations
         collectively, the "OBLIGATIONS").

                           Accordingly, UCAR and the Borrower, each Subsidiary
         Guarantor and the Collateral Agent agree as follows:

                           SECTION 1. INDEMNITY AND SUBROGATION. In addition to
         all such rights of indemnity and subrogation as the Subsidiary
         Guarantors may have under applicable law (but subject to Section 3),
         UCAR and the Borrower agree that (a) in the event a payment shall be
         made by any Subsidiary Guarantor under the Guarantee Agreement, UCAR
         and the Borrower shall indemnify such Subsidiary Guarantor for the full
         amount of such payment and such Subsidiary Guarantor shall be
         subrogated to the rights of the person to whom such payment shall have
         been made to the extent of such payment and (b) in the event any assets
         of any Subsidiary Guarantor shall be sold pursuant to any applicable
         security agreement or similar instrument or agreement to satisfy a
         claim of any Secured Party, UCAR and the Borrower shall indemnify such
         Subsidiary Guarantor in an amount equal to the greater of the book
         value or the fair market value of the assets so sold.

                           SECTION 2. CONTRIBUTION AND SUBROGATION. Each
         Subsidiary Guarantor agrees (subject to Section 3) that in the event a
         payment shall be made by any Subsidiary Guarantor under the Guarantee
         Agreement or assets of any Subsidiary Guarantor shall be sold pursuant
         to any applicable security agreement or similar instrument or agreement
         to satisfy a claim of any Secured Party, and such Subsidiary Guarantor
         (the "CLAIMING SUBSIDIARY GUARANTOR") shall not have been indemnified
         by UCAR or the Borrower as provided in Section 1, each other Subsidiary
         Guarantor (a "CONTRIBUTING SUBSIDIARY GUARANTOR") shall indemnify the
         Claiming Subsidiary Guarantor in an amount equal to the amount of such
         payment or the greater of the book value or the fair market value of
         such assets, as the case may be, multiplied by a fraction of which the
         numerator shall be the net worth of the Contributing Subsidiary
         Guarantor on the date hereof and the denominator shall be the aggregate

<PAGE>

                                                                          3

         net worth of all the Subsidiary Guarantors on the date hereof (or, in
         the case of any Subsidiary Guarantor becoming a party hereto pursuant
         to Section 16, the date of the Supplement hereto executed and delivered
         by such Subsidiary Guarantor). Any Contributing Subsidiary Guarantor
         making any payment to a Claiming Subsidiary Guarantor pursuant to this
         Section 2 shall be subrogated to the rights of such Claiming Subsidiary
         Guarantor under Section 1 to the extent of such payment.

                           SECTION 3. SUBORDINATION. Notwithstanding any
         provision of this Agreement to the contrary, all rights of the
         Subsidiary Guarantors under Sections 1 and 2 and all other rights of
         indemnity, contribution or subrogation under applicable law or
         otherwise shall be fully subordinated to the indefeasible payment in
         full of the Obligations. No failure on the part of UCAR, the Borrower
         or any Subsidiary Guarantor to make the payments required by Sections 1
         and 2 (or any other payments required under applicable law or
         otherwise) shall in any respect limit the obligations and liabilities
         of any other Subsidiary Guarantor with respect to any Guarantee, and
         each Subsidiary Guarantor shall remain liable for the full amount of
         the Obligations that such Subsidiary Guarantor has otherwise
         guaranteed.

                           SECTION 4. TERMINATION. This Agreement shall
         terminate when all the Obligations have been indefeasibly paid in full,
         no Letters of Credit are outstanding and the Secured Parties have no
         further Commitments under the Credit Agreement.

                           SECTION 5. CONTINUED EFFECTIVENESS. UCAR, the
         Borrower and each Subsidiary Guarantor further agree that this
         Agreement shall continue to be effective or be reinstated, as the case
         may be, if at any time payment, or any part thereof, of principal of or
         interest on any Obligation is rescinded or must otherwise be restored
         by any Secured Party or any Subsidiary Guarantor upon the bankruptcy or
         reorganization of UCAR, the Borrower, any Subsidiary Guarantor or
         otherwise.

                           SECTION 6. GOVERNING LAW. THIS AGREEMENT SHALL BE
         GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE
         OF NEW YORK.

                           SECTION 7. WAIVERS; AMENDMENT. (a) No failure or
         delay of the Collateral Agent, any Secured Party, or any Guarantor in
         exercising any power or right hereunder shall operate as a waiver
         thereof, nor shall any single or partial exercise of any such right or
         power or any abandonment or discontinuance of steps to enforce such a
         right or power preclude any other or further exercise thereof or the
         exercise of any other right or power. The rights and the remedies of
         the Secured Parties under the other Loan Documents are cumulative and
         are not exclusive of any rights or remedies that they would otherwise
         have. No waiver of any provisions of this Agreement or consent to any
         departure by any Subsidiary Guarantor therefrom shall in any event be
         effective unless the same shall be permitted by paragraph (b) below,
         and then such waiver or consent shall be effective only in the specific
         instance and for the purpose for which given. No notice or demand on

<PAGE>
                                                                        4

         any Subsidiary Guarantor in any case shall entitle such Subsidiary
         Guarantor to any other or further notice or demand in similar or other
         circumstances.

                           (b) Except for the operation of Section 16 of this
         Agreement, neither this Agreement nor any provision hereof may be
         waived, amended or modified except pursuant to a written agreement
         entered into between the Subsidiary Guarantors and the Collateral
         Agent, with the prior written consent of the Required Lenders.

                           SECTION 8. NOTICES. All communications and notices
         hereunder shall be in writing and given as provided in the Credit
         Agreement, except those to any Subsidiary Guarantor that is not an LC
         Subsidiary, which shall be directed to the address set forth under its
         signature below.

                           SECTION 9. BINDING AGREEMENT; ASSIGNMENTS. This
         Agreement shall become effective as to each of UCAR, the Borrower or
         any Subsidiary Guarantor when a counterpart hereof executed on behalf
         of UCAR, the Borrower or such Subsidiary Guarantor shall have been
         delivered to the Collateral Agent and a counterpart hereof shall have
         been executed on behalf of the Collateral Agent, and thereafter shall
         be binding upon each of UCAR, the Borrower or such Subsidiary Guarantor
         and the Collateral Agent and their respective successors and permitted
         assigns, and shall inure to the benefit of such Subsidiary Guarantor
         and the Secured Parties, and their respective successors and permitted
         assigns, except that no Subsidiary Guarantor shall have the right to
         assign its rights hereunder or any interest herein (and any such
         attempted assignment shall be void), except as expressly contemplated
         by this Agreement or the other Loan Documents.

                           SECTION 10. SUCCESSORS AND ASSIGNS. Whenever in this
         Agreement any of the parties hereto is referred to, such reference
         shall be deemed to include the successors and permitted assigns of such
         party, and all covenants, promises and agreements by or on behalf of
         each of UCAR, the Borrower or any Subsidiary Guarantor or the
         Collateral Agent that are contained in this Agreement shall bind and
         inure to the benefit of their respective successors and permitted
         assigns.

                           SECTION 11. SURVIVAL OF AGREEMENT; SEVERABILITY. (a)
         All covenants, agreements, representations and warranties made by each
         of UCAR, the Borrower and each Subsidiary Guarantor herein and in any
         certificates or other instruments prepared or delivered in connection
         with or pursuant to this Agreement or any other Loan Document shall be
         considered to have been relied upon by the Secured Parties and each
         Subsidiary Guarantor and shall survive the making by the Lenders of the
         Loans, the execution and delivery to the Lenders of the Loan Documents
         and the issuance by the Issuing Bank of Letters of Credit, regardless
         of any investigation made by the Secured Parties or on their behalf,
         and shall continue in full force and effect as long as the principal of
         or any accrued interest on any Loan or LC Disbursement or any Fee or
         any other amount payable under, or in respect of, this Agreement or
         under any of the other Loan Documents is outstanding and unpaid and so
         long as any Letter of Credit is outstanding and so long as the
         Commitments have not been terminated.

                                                                        5

                           (b) In the event any one or more of the provisions
         contained in this Agreement or in any other Loan Document should be
         held invalid, illegal or unenforceable in any respect, the validity,
         legality and enforceability of the remaining provisions contained
         herein and therein shall not in any way be affected or impaired thereby
         (it being understood that the invalidity of a particular provision in a
         particular jurisdiction shall not in and of itself affect the validity
         of such provision in any other jurisdiction). The parties shall
         endeavor in good-faith negotiations to replace the invalid, illegal or
         unenforceable provisions with valid provisions, the economic effect of
         which comes as close as possible to that of the invalid, illegal or
         unenforceable provisions.

                           SECTION 12. COUNTERPARTS. This Agreement may be
executed in two or more counterparts, each of which shall constitute an
original, but all of which, when taken together, shall constitute but one
instrument.

                           SECTION 13. RULES OF INTERPRETATION. The rules of
interpretation specified in Section 1.03 of the Credit Agreement shall be
applicable to this Agreement.

                           SECTION 14. JURISDICTION; CONSENT TO SERVICE OF
         PROCESS. (a) Each of UCAR, the Borrower and each Subsidiary Guarantor
         hereby irrevocably and unconditionally submits, for itself and its
         property, to the nonexclusive jurisdiction of any New York State court
         or Federal court of the United States of America sitting in New York
         City, and any appellate court from any thereof, in any action or
         proceeding arising out of or relating to this Agreement, or for
         recognition or enforcement of any judgment related to any such action
         or proceeding, and each of the parties hereto hereby irrevocably and
         unconditionally agrees that all claims in respect of any such action or
         proceeding may be heard and determined in such New York State or, to
         the extent permitted by law, in such Federal court. Each of the parties
         hereto agrees that a final judgment in any such action or proceeding
         shall be conclusive and may be enforced in other jurisdictions by suit
         on the judgment or in any other manner provided by law. Nothing in this
         Agreement shall affect any right that any Loan Party or any Secured
         Party may otherwise have to bring any action or proceeding relating to
         this Agreement against UCAR, the Borrower or any Subsidiary Guarantor
         or any Secured Party or their properties in the courts of any
         jurisdiction.

                           (b) Each of UCAR, the Borrower, each Subsidiary
         Guarantor and each Secured Party hereby irrevocably and unconditionally
         waives, to the fullest extent it may legally and effectively do so, any
         objection it may now or hereafter have to the laying of venue of any
         suit, action or proceeding arising out of or relating to this Agreement
         in any New York State or Federal court. Each of the parties hereto
         hereby irrevocably waives, to the fullest extent permitted by law, the
         defense of an inconvenient forum to the maintenance of such action or
         proceeding in any such court.

                           (c) Each party to this Agreement irrevocably consents
         to service of process in the manner provided for notices in Section 8.
         Nothing in this Agreement will affect the right of any party to this
         Agreement to serve process in any other manner permitted by law.

                           SECTION 15. WAIVER OF JURY TRIAL. EACH PARTY HERETO
         HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY
         RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION
         DIRECTLY OR INDIRECTLY ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS

         AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR
         OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION,
         SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND
         THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT
         BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS
         SECTION 15.

                           SECTION 16. ADDITIONAL SUBSIDIARY GUARANTORS.
         Pursuant to Section 6.11 of the Credit Agreement, each Domestic
         Subsidiary that was not in existence or not a Subsidiary on the date

                            SUPPLEMENT NO. dated as of [ ], to
                 the Indemnity, Subrogation and Contribution
                 Agreement dated February 22, 2000 (the
                 "INDEMNITY, SUBROGATION AND CONTRIBUTION
                 AGREEMENT"), among UCAR INTERNATIONAL INC.,
                 a Delaware corporation ("UCAR"), UCAR
                 FINANCE INC., a Delaware corporation (the
                 "BORROWER"), each of the Subsidiary
                 Guarantors (each capitalized term used but
                 not defined having the meaning given it in
                 the Indemnity, Subrogation and Contribution
                 Agreement or the Credit Agreement) party
                 thereto and MORGAN GUARANTY TRUST COMPANY OF
                 NEW YORK, as Collateral Agent for the
                 Secured Parties.

                           A. Reference is made to Credit Agreement dated as of
         February 22, 2000 (as the same may be amended, supplemented or
         otherwise modified from time to time, the "CREDIT AGREEMENT"), among
         UCAR, UCAR Global Enterprises Inc., a Delaware corporation ("GLOBAL"),
         the Borrower, the LC Subsidiaries from time to time party thereto, the
         Lenders from time to time party thereto and Morgan Guaranty Trust
         Company of New York, as Administrative Agent, Collateral Agent and
         Issuing Bank.

                           B. Certain Subsidiary Guarantors have entered into
         the Indemnity, Subrogation and Contribution Agreement in order to
         induce the Lenders to make Loans and the Issuing Bank to issue Letters
         of Credit pursuant to, and upon the terms and subject to the conditions
         specified in, the Credit Agreement. Pursuant to Section 6.11 of the
         Credit Agreement, promptly after its creation or acquisition, each
         additional Domestic Subsidiary is required to become a party to the
         Indemnity, Subrogation and Contribution Agreement as a Subsidiary
         Guarantor. Section 16 of the Indemnity, Subrogation and Contribution
         Agreement provides that additional Domestic Subsidiaries may become
         Subsidiary Guarantors under the Indemnity, Subrogation and Contribution
         Agreement by execution and delivery of an instrument in the form of
         this Supplement. The undersigned (the "NEW SUBSIDIARY GUARANTOR") is a
         Domestic. Subsidiary and is executing this Supplement in accordance
         with the requirements of the Credit Agreement to become a Subsidiary
         Guarantor under the Indemnity, Subrogation and Contribution Agreement
         in order to induce the Lenders to make additional Loans and the
         Fronting Banks to issue additional Letters of Credit and as
         consideration for Loans previously made and Letters of Credit
         previously issued.

                           Accordingly, the Collateral Agent and the New
Subsidiary Guarantor agree as follows:

                           SECTION 1. In accordance with Section 16 of the
         Indemnity, Subrogation and Contribution Agreement, the New Subsidiary
         Guarantor by its signature below becomes a Subsidiary Guarantor under

                                                                        2

         the Indemnity, Subrogation and Contribution Agreement with the same
         force and effect as if originally named therein as a Subsidiary
         Guarantor and the New Subsidiary Guarantor hereby agrees to all the
         terms and provisions of the Indemnity, Subrogation and Contribution
         Agreement applicable to it as a Subsidiary Guarantor thereunder. Each
         reference to a "Subsidiary Guarantor" in the Indemnity, Subrogation and
         Contribution Agreement shall be deemed to include the New Subsidiary
         Guarantor. The Indemnity, Subrogation and Contribution Agreement is
         hereby incorporated herein by reference.

                           SECTION 2. The New Subsidiary Guarantor represents
         and warrants to the Secured Parties that this Supplement has been duly
         authorized, executed and delivered by it and constitutes its legal,
         valid and binding obligation, enforceable against it in accordance with
         its terms, subject to the effects of applicable bankruptcy, insolvency
         or similar laws affecting creditors' rights generally and equitable
         principles of general applicability.

                           SECTION 3. This Supplement may be executed in two or
         more counterparts, each of which shall constitute an original, but all
         of which, when taken together, shall constitute but one instrument.
         This Supplement shall become effective when the Collateral Agent shall
         have received counterparts of this Supplement that, when taken
         together, bear the signatures of the New Subsidiary Guarantor and the
         Collateral Agent.

                           SECTION 4. Except as expressly supplemented hereby,
         the Indemnity, Subrogation and Contribution Agreement shall remain in
         full force and effect.

                           SECTION 5. THIS SUPPLEMENT SHALL BE GOVERNED BY, AND
         CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

                           SECTION 6. If any one or more of the provisions
         contained in this Supplement should be held invalid, illegal or
         unenforceable in any respect, neither party hereto shall be required to
         comply with such provision for so long as such provision is held to be
         invalid, illegal or unenforceable, but the validity, legality and
         enforceability of the remaining provisions contained herein and in the
         Indemnity, Subrogation and Contribution Agreement shall not in any way
         be affected or impaired. The parties hereto shall endeavor in
         good-faith negotiations to replace the invalid, illegal or
         unenforceable provisions with valid provisions the economic effect of
         which comes as close as possible to that of the invalid, illegal or
         unenforceable provisions.

                           SECTION 7. All communications and notices hereunder
         shall be in writing and given as provided in the Credit Agreement. All
         communications and notices hereunder to the New Subsidiary Guarantor
         shall be given to it at the address set forth under its signature, with
         a copy to the Borrower.
