      Agreement and all communications  with the Company regarding the Agreement
      confidential.

      10. Non-Competition and Non-Solicitation.

            10.1.  The Executive  agrees that prior to December 31, 2006 he will
      not,  directly or indirectly,  on behalf of anyone other than the Company,
      solicit or accept  sales or  employment  from (i) any current  information
      services customer of the Company, (ii) any entity which was an information
      services customer of the Company at any time within two (2) years prior to
      the date of this Agreement,  (iii) any entity for which the Company has an
      outstanding  proposal  for  information  services  business  or is in  the
      process of  preparing  such a proposal  as of  February  28,  2005 or (iv)
      Ticketmaster or any of its affiliates.

            10.2. The Executive  agrees that prior to December 31, 2006, he will
      not, directly or indirectly,  solicit any person who is an employee of the
      Company to terminate his or her relationship with the Company.

            10.3. The Executive  agrees that prior to December 31, 2006, he will
      not, directly or indirectly,  acquire any debt, equity, or other ownership
      interest in any person or entity engaged in a business  competitive to the
      Company's  information services business except that the Executive may own
      in the aggregate not more than one percent (1%) of the outstanding  equity
      of any publicly-traded entity engaged in such a competitive business.

            10.4. The Executive  acknowledges  that monetary  damages may not be
      sufficient  to  compensate  the Company for any economic loss which may be
      incurred    by    reason    of    his    breach    of    the     foregoing
      none-compete/non-solicitation agreements. Accordingly, in the event of any
      such breach,  the Company shall, in addition to any remedies  available to
      the Company at law, be entitled to obtain  equitable relief in the form of
      an injunction  precluding the Executive from continuing  such breach.  The
      existence of this right shall

                                       6
<PAGE>

      not  preclude  any other rights and remedies at law or in equity which the
      Company may have. The parties agree that the  restrictions  and agreements
      contained  herein  are  reasonable,   are  the  product  of  arm's  length
      negotiation,  and are  necessary  for the Company to protect its business;
      however, in the event that any part of this Paragraph 10 shall be found to
      be  unenforceable,  but would be valid and enforceable if any part thereof
      were  deleted  or  otherwise  modified,  then  such  restrictions  in this
      Paragraph 10 shall apply with such  modifications,  but only to the extent
      as shall be necessary to make them valid and enforceable.

      11. Breach by the  Executive.  The Company's  obligations to the Executive
under this  Agreement  are  contingent  on the  Executive's  performance  of his
agreements  and  obligations  under  this  Agreement.  Any  material  breach  by
Executive of his  obligations  under this Agreement will result in the immediate
cancellation  of all  Executive  stock  options,  the immediate  termination  of
Executive's employment, as well as entitle the Company to all its other remedies
in law or equity,  including but not limited to a claim for reimbursement of all
amounts paid to the Executive hereunder.

      12.  Executive  Availability.  The Executive  agrees to promptly  supply a
brief summary of open  projects/items  he was working on together with a list of
action items related to such matters and to make himself reasonably available to
the Company to respond to requests by the Company for information  pertaining to
or relating to the Company and/or the Company's  affiliates,  agents,  Officers,
Directors or employees  which may be within the knowledge of the Executive.  The
Executive will cooperate  fully with the Company in connection  with any and all
existing  or future  litigation  or  investigations  brought by or  against  the
Company or any of its past or present affiliates, agents, Officers, Directors or
employees  whether  administrative,  civil or criminal in nature in which and to
the extent the Company deems the Executive's cooperation necessary.  The Company
will reimburse the Executive for reasonable out-of-pocket expenses incurred as a
result of such  cooperation.  If more than 8 hours of his time is required after
February 28, 2005, Executive will be compensated at his currently hourly rate.

      13. Non Disparagement. The Executive agrees that he will not make or cause
to be made any  statements  that  disparage,  are  inimical  to, or  damage  the
reputation   of  the  Company  or  any  of  its  past  or  present   affiliates,
subsidiaries,  agents,  Officers,  Directors  or  employees.  In the event  such
communication is made to anyone,  it will be considered a material breach of the
terms of this Agreement. The Company agrees it will not make or cause to be made
any statements that disparage,  are inimical to, or damage the reputation of the
Executive.

      14.  Severability  of Provisions.  In the event that any provision of this
Agreement is determined to be legally invalid or  unenforceable  by any court of
competent  jurisdiction  and cannot be modified to be enforceable,  the affected
provision  shall be stricken from the Agreement,  and the remaining terms of the
Agreement and its enforceability shall remain unaffected.

      15.  Right to  Revoke  this  Agreement.  The  Executive  may  revoke  this
Agreement  in writing  within  seven (7) days of  signing it . If the  Executive
timely revokes this Agreement in a

                                       7

signed writing delivered to the Chairman of the Board of the Company, all of its
provisions shall be void and unenforceable.

      16. Entire Agreement.

            16.1. This Agreement  constitutes the entire  understanding  between
      the parties.  The parties have not relied on any oral  statements that are
      not included in the Agreement. Any modifications to this Agreement must be
      in writing and signed by the  Executive  and the  Chairman of the Board of
      the Company.

            16.2. The Executive acknowledges and reaffirms the provisions of the
      Employee  Confidentiality  Agreement  he  executed  as an  employee of the
      Company.   Any   conflict   between  the   provisions   of  the   Employee
      Confidentiality Agreement and this Agreement shall be resolved in favor of
      the provisions of this Agreement.

      17.  Governing Law. This  Agreement  shall be construed,  interpreted  and
applied in  accordance  with the laws of the State of Maryland,  without  giving
effect to the choice of law provisions thereof.

such other certifications and evidence as the Company may reasonably require)
that a Note is eligible for resale pursuant to Rule 144(k) under the Securities

(x) sold pursuant to an effective registration statement under the Securities
Act, pursuant to the Registration Rights Agreement or otherwise, or (y) is

Note or Initial Additional Note that is an Offshore Global Note upon termination

beneficial interest) only in accordance with the Indenture and such legend.

                  (i)      Initial Notes for original issue in the aggregate

                  (ii)     Initial Additional Notes from time to time for
         original issue in aggregate principal amounts specified by the Company,
         and

         exchange for a like principal amount of Initial Notes or Initial
         Additional Notes after the following conditions have been met:

                  (1)      Receipt by the Trustee of an Officers' Certificate
         specifying

                           (A)      the amount of Notes to be authenticated and
                  the date on which the Notes are to be authenticated,

                           (B)      whether the Notes are to be Initial Notes,
                  Additional Notes or Exchange Notes,

                           (C)      in the case of Additional Notes, that the
                  issuance of such Notes does not contravene any provision of
                  Article 4,

                           (D)      whether the Notes are to be issued as one or
                  more Global Notes or Certificated Notes, and

                           (E)      other information the Company may determine
                  to include or the Trustee may reasonably request.

                  (2)      In the case of Initial Additional Notes, receipt by
         the Trustee of an Opinion of Counsel confirming that (subject to
         customary assumptions) the Holders of the outstanding Notes will be
         subject to federal income tax in the same amounts, in the same manner
         and at the same times as would have been the case if such Additional
         Notes were not issued.

                  (3)      In the case of Exchange Notes, effectiveness of an
         Exchange Offer Registration Statement and consummation of the exchange
         offer thereunder (and receipt by the Trustee of an Officers'
         Certificate to that effect). Initial Notes or Initial Additional Notes
         exchanged for Exchange Notes will be cancelled by the Trustee.

         Section 2.03. Registrar, Paying Agent and Authenticating Agent; Paying
Agent to Hold Money in Trust. (a) The Company may appoint one or more Registrars
and one or more Paying Agents, and the Trustee may appoint an Authenticating
Agent, in which case each reference in the Indenture to the Trustee in respect
of the obligations of the Trustee to be performed by that Agent will be

                                       31
<PAGE>

deemed to be references to the Agent. The Company may act as Registrar or
(except for purposes of Article 8) Paying Agent. In each case the Company and
the Trustee will enter into an appropriate agreement with the Agent implementing
the provisions of the Indenture relating to the obligations of the Trustee to be
performed by the Agent and the related rights. The Company initially appoints
the Trustee as Registrar and Paying Agent.

         (b)      The Company will require each Paying Agent other than the
Trustee to agree in writing that the Paying Agent will hold in trust for the
benefit of the Holders or the Trustee all money held by the Paying Agent for the
payment of principal of and interest on the Notes and will promptly notify the
Trustee of any default by the Company in making any such payment. The Company at
any time may require a Paying Agent to pay all money held by it to the Trustee
and account for any funds disbursed, and the Trustee may at any time during the
continuance of any payment default, upon written request to a Paying Agent,
require the Paying Agent to pay all money held by it to the Trustee and to
account for any funds disbursed. Upon doing so, the Paying Agent will have no
further liability for the money so paid over to the Trustee.

         Section 2.04. Replacement Notes. If a mutilated Note is surrendered to
the Trustee or if a Holder claims that its Note has been lost, destroyed or
wrongfully taken, the Company will issue and the Trustee will authenticate a
replacement Note of like tenor and principal amount and bearing a number not
contemporaneously outstanding. Every replacement Note is an additional
obligation of the Company and entitled to the benefits of the Indenture. If
required by the Trustee or the Company, an indemnity must be furnished that is
sufficient in the judgment of both the Trustee and the Company to protect the
Company and the Trustee from any loss they may suffer if a Note is replaced. The
Company may charge the Holder for the expenses of the Company and the Trustee in
replacing a Note. In case the mutilated, lost, destroyed or wrongfully taken
Note has become or is about to become due and payable, the Company in its
discretion may pay the Note instead of issuing a replacement Note.

         Section 2.05. Outstanding Notes. (a) Notes outstanding at any time are
all Notes that have been authenticated by the Trustee except for

                  (i)      Notes cancelled by the Trustee or delivered to it for
         cancellation;

                  (ii)     any Note which has been replaced pursuant to Section
         2.04 unless and until the Trustee and the Company receive proof
         satisfactory to them that the replaced Note is held by a protected
         purchaser; and

                  (iii)    on or after the maturity date or any redemption date
         or date for purchase of the Notes pursuant to an Offer to Purchase,
         those Notes

                                       32
<PAGE>

         payable or to be redeemed or purchased on that date for which the
         Trustee (or Paying Agent, other than the Company or an Affiliate of the
         Company) holds money sufficient to pay all amounts then due.

         (b)      A Note does not cease to be outstanding because the Company or
one of its Affiliates holds the Note, provided that in determining whether the
Holders of the requisite principal amount of the outstanding Notes have given or
taken any request, demand, authorization, direction, notice, consent, waiver or
other action hereunder, Notes owned by the Company or any Affiliate of the
Company will be disregarded and deemed not to be outstanding, (it being
understood that in determining whether the Trustee is protected in relying upon
any such request, demand, authorization, direction, notice, consent, waiver or
other action, only Notes which a Responsible Officer of the Trustee knows to be
so owned will be so disregarded). Notes so owned which have been pledged in good
faith may be regarded as outstanding if the pledgee establishes to the
satisfaction of the Trustee the pledgee's right so to act with respect to such
Notes and that the pledgee is not the Company or any Affiliate of the Company.

         Section 2.06. Temporary Notes. Until definitive Notes are ready for
delivery, the Company may prepare and the Trustee will authenticate temporary
Notes. Temporary Notes will be substantially in the form of definitive Notes but
may have insertions, substitutions, omissions and other variations determined to
be appropriate by the Officer executing the temporary Notes, as evidenced by the
execution of the temporary Notes. If temporary Notes are issued, the Company
will cause definitive Notes to be prepared without unreasonable delay. After the
preparation of definitive Notes, the temporary Notes will be exchangeable for
definitive Notes upon surrender of the temporary Notes at the office or agency
of the Company designated for the purpose pursuant to Section 4.02, without
charge to the Holder. Upon surrender for cancellation of any temporary Notes the
Company will execute and the Trustee will authenticate and deliver in exchange
therefor a like principal amount of definitive Notes of authorized
denominations. Until so exchanged, the temporary Notes will be entitled to the
same benefits under the Indenture as definitive Notes.

         Section 2.07. Cancellation. The Company at any time may deliver to the
Trustee for cancellation any Notes previously authenticated and delivered
hereunder which the Company may have acquired in any manner whatsoever, and may
deliver to the Trustee for cancellation any Notes previously authenticated
hereunder which the Company has not issued and sold. Any Registrar or the Paying
Agent will forward to the Trustee any Notes surrendered to it for transfer,
exchange or payment. The Trustee will cancel all Notes surrendered for transfer,
exchange, payment or cancellation and dispose of them in accordance with its
normal procedures or the written instructions of the Company. The Company may
not issue new Notes to replace Notes it has paid in full or delivered to the
Trustee for cancellation.

                                       33
<PAGE>

         Section 2.08. CUSIP and CINS Numbers. The Company in issuing the Notes
may use "CUSIP" and "CINS" numbers, and the Trustee will use CUSIP numbers or
CINS numbers in notices of redemption or exchange or in Offers to Purchase as a
convenience to Holders, the notice to state that no representation is made as to
the correctness of such numbers either as printed on the Notes or as contained
in any notice of redemption or exchange or Offer to Purchase. The Company will
promptly notify the Trustee in writing of any change in the CUSIP or CINS
numbers.

         Section 2.09. Registration, Transfer and Exchange. (a) The Notes will
be issued in registered form only, without coupons, and the Company shall cause
the Trustee to maintain a register (the "REGISTER") of the Notes, for
registering the record ownership of the Notes by the Holders and transfers and
exchanges of the Notes.

         (a)      (i) Each Global Note will be registered in the name of the
Depositary or its nominee and, so long as DTC is serving as the Depositary
thereof, will bear the DTC Legend.

                  (ii)     Each Global Note will be delivered to the Trustee as
         custodian for the Depositary. Transfers of a Global Note (but not a
         beneficial interest therein) will be limited to transfers thereof in
         whole, but not in part, to the Depositary, its successors or their
         respective nominees, except (A) as set forth in Section 2.10(b)(iv) and
         (B) transfers of portions thereof in the form of Certificated Notes may
         be made upon request of an Agent Member (for itself or on behalf of a
         beneficial owner) by written notice given to the Trustee by or on
         behalf of the Depositary in accordance with customary procedures of the
         Depositary and in compliance with this Section and Section 2.10.

                  (iii)    Agent Members will have no rights under the Indenture
         with respect to any Global Note held on their behalf by the Depositary,
         and the Depositary may be treated by the Company, the Trustee and any
         agent of the Company or the Trustee as the absolute owner and Holder of
         such Global Note for all purposes whatsoever. Notwithstanding the
         foregoing, the Depositary or its nominee may grant proxies and
         otherwise authorize any Person (including any Agent Member and any
         Person that holds a beneficial interest in a Global Note through an
         Agent Member) to take any action which a Holder is entitled to take
         under the Indenture or the Notes, and nothing herein will impair, as
         between the Depositary and its Agent Members, the operation of
         customary practices governing the exercise of the rights of a holder of
         any security.

                  (iv)     If (x) the Depositary notifies the Company that it is
         unwilling or unable to continue as Depositary for a Global Note and a

                                       34
<PAGE>

         successor depositary is not appointed by the Company within 90 days of
         the notice or (y) an Event of Default has occurred and is continuing
         and the Trustee has received a request from the Depositary, the Trustee
         will promptly exchange each beneficial interest in the Global Note for
         one or more Certificated Notes in authorized denominations having an
         equal aggregate principal amount registered in the name of the owner of
         such beneficial interest, as identified to the Trustee by the
         Depositary, and thereupon the Global Note will be deemed canceled. If
         such Note was an Offshore Global Note, then the Certificated Notes
         issued in exchange therefore will not bear a Restricted Legend.

         (c)      Each Certificated Note will be registered in the name of the
holder thereof or its nominee.

         (d)      A Holder may transfer a Note (or a beneficial interest
therein) to another Person or exchange a Note (or a beneficial interest therein)
for another Note or Notes of any authorized denomination by presenting to the
Trustee a written request therefor stating the name of the proposed transferee
or requesting such an exchange, accompanied by any certification, opinion or
other document required by Section 2.10. The Trustee will promptly register any
transfer or exchange that meets the requirements of this Section by noting the
same in the register maintained by the Trustee for the purpose; provided that

                  (i)      no transfer or exchange will be effective until it is
         registered in such register and

                  (ii)     the Trustee will not be required (A) to issue,
         register the transfer of or exchange any Note for a period of 15 days
         before a selection of Notes to be redeemed or purchased pursuant to an
         Offer to Purchase, (B) to register the transfer of or exchange any Note
         so selected for redemption or purchase in whole or in part, except, in
         the case of a partial redemption or purchase, that portion of any Note
         not being redeemed or purchased, or (C) if a redemption or a purchase
         pursuant to an Offer to Purchase is to occur after a Regular Record
         Date but on or before the corresponding Interest Payment Date, to
         register the transfer of or exchange any Note on or after the Regular
         Record Date and before the date of redemption or purchase. Prior to the
         registration of any transfer, the Company, the Trustee and their agents
         will treat the Person in whose name the Note is registered as the owner
         and Holder thereof for all purposes (whether or not the Note is
         overdue), and will not be affected by notice to the contrary.

         From time to time the Company will execute and the Trustee will
authenticate additional Notes as necessary in order to permit the registration
of a transfer or exchange in accordance with this Section.

                                       35
<PAGE>

         No service charge will be imposed in connection with any registration
of transfer or exchange of any Note, but the Company or the Trustee may require
payment of a sum sufficient to cover any transfer tax or similar governmental
charge payable in connection therewith (other than a transfer tax or other
similar governmental charge payable upon exchange pursuant to subsection
(b)(iv)).

         (e)      (i) Global Note to Global Note. If a beneficial interest in a
Global Note is transferred or exchanged for a beneficial interest in another
Global Note, the Trustee will (x) record a decrease in the principal amount of
the Global Note being transferred or exchanged equal to the principal amount of
such transfer or exchange and (y) record a like increase in the principal amount
of the other Global Note. Any beneficial interest in one Global Note that is
transferred to a Person who takes delivery in the form of an interest in another
Global Note, or exchanged for an interest in another Global Note, will, upon
registration of transfer or exchange, cease to be an interest in such Global
Note and become an interest in the other Global Note and, accordingly, will
thereafter be subject to all transfer and exchange restrictions, if any, and
other procedures applicable to beneficial interests in such other Global Note
for as long as it remains such an interest.

                  (ii)     Global Note to Certificated Note. If a beneficial
         interest in a Global Note is transferred or exchanged for a
         Certificated Note, the Trustee will (x) record a decrease in the
         principal amount of such Global Note equal to the principal amount of
         such transfer or exchange and (y) deliver one or more new Certificated
         Notes in authorized denominations having an equal aggregate principal
         amount to the transferee (in the case of a transfer) or the owner of

         increase in the principal amount of such Global Note equal to the

         Note, the Trustee will (x) cancel the Certificated Note being
         transferred or exchanged, (y) deliver one or more new Certificated
         Notes in authorized denominations

         such transfer or exchange to the transferee (in the case of a transfer)
         or the Holder of the canceled Certificated Note (in the case of an
         exchange), registered in the name of such transferee or Holder, as
         applicable, and (z) if such transfer or exchange involves less than the
         entire principal amount of the canceled Certificated Note, deliver to
         the Holder thereof one or more Certificated Notes in authorized
         denominations having an aggregate principal amount equal to the
         untransferred or unexchanged portion of the canceled Certificated Note,
         registered in the name of the Holder thereof.

Notes with the net cash proceeds received by the Company from any Public Equity
Offering at a redemption price equal to 107.50% of the principal amount plus
accrued and unpaid interest to the redemption date, in an aggregate principal
amount for all such redemptions not to exceed 35% of the aggregate principal
amount of the Notes originally issued under the Indenture, provided that

after the closing of the related Public Equity Offering, and

         (b)      not less than 65% of the aggregate principal amount of the
Original Notes remains outstanding immediately thereafter.

         Section 3.03. Method and Effect of Redemption. (a) If the Company
elects to redeem Notes, it must notify the Trustee of the redemption date and
the

                                       39
<PAGE>

principal amount of Notes to be redeemed by delivering an Officers' Certificate
at least 60 days before the redemption date (unless a shorter period is
satisfactory to the Trustee). If fewer than all of the Notes are being redeemed,
the Officers' Certificate must also specify a record date not less than 15 days
after the date of the notice of redemption is given to the Trustee, and the
Trustee will select the Notes to be redeemed pro rata, by lot or by any other
method the Trustee in its sole discretion deems fair and appropriate, in
denominations of $1,000 principal amount and multiples thereof. The Trustee will
notify the Company promptly of the Notes or portions of Notes to be called for
redemption. Notice of redemption must be sent by the Company or at the Company's
request, by the Trustee in the name and at the expense of the Company, to
Holders whose Notes are to be redeemed at least 30 days but not more than 60
days before the redemption date.

         (b)      The notice of redemption will identify the Notes to be
redeemed and will include or state the following:

                  (i)      the redemption date;

                  (ii)     the redemption price, including the portion thereof
         representing any accrued interest;

                  (iii)    the place or places where Notes are to be surrendered
         for redemption;

                  (iv)     Notes called for redemption must be so surrendered in
         order to collect the redemption price;

                  (v)      on the redemption date the redemption price will
         become due and payable on Notes called for redemption, and interest on
         Notes called for redemption will cease to accrue on and after the
         redemption date;

                  (vi)     if any Note is redeemed in part, on and after the
         redemption date, upon surrender of such Note, new Notes equal in
         principal amount to the unredeemed portion will be issued; and

                  (vii)    if any Note contains a CUSIP or CINS number, no
         representation is being made as to the correctness of the CUSIP or CINS
         number either as printed on the Notes or as contained in the notice of
         redemption and that the Holder should rely only on the other
         identification numbers printed on the Notes.

         (c)      Once notice of redemption is sent to the Holders, Notes called
for redemption become due and payable at the redemption price on the redemption
date, and upon surrender of the Notes called for redemption, the Company shall

                                       40
<PAGE>

redeem such Notes at the redemption price. Commencing on the redemption date,
Notes redeemed will cease to accrue interest. Upon surrender of any Note
redeemed in part, the Holder will receive a new Note equal in principal amount
to the unredeemed portion of the surrendered Note.

         Section 3.04. Offer to Purchase. (a) An "OFFER TO PURCHASE" means an
offer by the Company to purchase Notes as required by the Indenture. An Offer to
Purchase must be made by written offer (the "OFFER") sent to the Holders. The
Company will notify the Trustee at least 15 days (or such shorter period as is
acceptable to the Trustee) prior to sending the offer to Holders of its
obligation to make an Offer to Purchase, and the offer will be sent by the
Company or, at the Company's request, by the Trustee in the name and at the

         and its Subsidiaries which the Company in good faith believes will
         enable the Holders to make an informed decision with respect to the
         Offer to Purchase, at a minimum to include or incorporate by reference

                  events requiring the Company to make the Offer to Purchase;

                  (vi)     a Holder may tender all or any portion of its Notes,

         offer will be required to surrender such Note at the place or places
         specified in the offer prior to the close of business on the expiration
         date (such Note being, if the Company or the Trustee so requires, duly
         endorsed or accompanied by a duly executed written instrument of

                  (ix)     interest on any Note not tendered, or tendered but
         not purchased by the Company pursuant to the Offer to Purchase, will
         continue to accrue;

                  (x)      on the purchase date the purchase price will become

         of the outstanding Notes and Notes in an aggregate principal amount in
         excess of the purchase amount are tendered and not withdrawn pursuant
         to the offer, the Company will purchase Notes having an aggregate
         principal amount equal to the purchase amount on a pro rata basis, with
         adjustments so that only Notes in multiples of $1,000 principal amount
         will be purchased;

                                       42
<PAGE>

                  (xiii)   if any Note is purchased in part, new Notes equal in
         principal amount to the unpurchased portion of the Note will be issued;
         and

price will become due and payable on each Note accepted for purchase, and
interest on Notes purchased will cease to accrue on and after the purchase date.

                                    COVENANTS

         Section 4.01. Payment of Notes. (a) The Company agrees to pay the
principal of and interest on the Notes on the dates and in the manner provided
in the Notes and the Indenture. Not later than 9:00 A.M. (New York City time) on
the due date of any principal of or interest on any Notes, or any redemption or
purchase price of the Notes, the Company will deposit with the Trustee (or
Paying Agent) money in immediately available funds sufficient to pay such
amounts, provided that if the Company or any Affiliate of the Company is acting
as Paying Agent, it will, on or before each due date, segregate and hold in a
separate trust fund for the benefit of the Holders a sum of money sufficient to
pay such amounts until paid to such Holders or otherwise disposed of as provided
in the Indenture. In each case the Company will promptly notify the Trustee of
its compliance with this paragraph.

         (b)      An installment of principal or interest will be considered
paid on the date due if the Trustee (or Paying Agent, other than the Company or
any Affiliate of the Company) holds on that date money designated for and
sufficient to pay the installment. If the Company or any Affiliate of the
Company acts as Paying

                                       43
<PAGE>

Agent, an installment of principal or interest will be considered paid on the
due date only if paid to the Holders.

         (c)      The Company agrees to pay interest on overdue principal and
overdue installments of interest at the rate per annum specified in the Notes.

         (d)      Payments in respect of the Notes represented by the Global
Notes are to be made by wire transfer of immediately available funds to the
accounts specified by the Holders of the Global Notes. With respect to
Certificated Notes, the Company will make all payments by mailing a check to
each Holder's registered address or, at the Company's option, by wire transfer
of immediately available funds to the accounts specified by the Holders thereof.

         Section 4.02. Maintenance of Office or Agency. The Company will
maintain in the Borough of Manhattan, The City of New York or Wilmington,
Delaware, an office or agency where Notes may be surrendered for registration of
transfer or exchange or for presentation for payment and where notices and
demands to or upon the Company in respect of the Notes and the Indenture may be
served. The Company hereby initially designates the Corporate Trust Office of
the Trustee as such office of the Company. The Company will give prompt written
notice to the Trustee of the location, and any change in the location, of such
office or agency. If at any time the Company fails to maintain any such required
office or agency or fails to furnish the Trustee with the address thereof, such
presentations, surrenders, notices and demands may be made or served to the
Trustee.

         The Company may also from time to time designate one or more other
offices or agencies where the Notes may be surrendered or presented for any of
such purposes and may from time to time rescind such designations. The Company
will give prompt written notice to the Trustee of any such designation or
rescission and of any change in the location of any such other office or agency.

         Section 4.03. Existence. The Company will do or cause to be done all
things necessary to preserve and keep in full force and effect its existence and
the existence of each of its Restricted Subsidiaries in accordance with their
respective organizational documents, and the material rights, licenses and
franchises of the Company and each Restricted Subsidiary, provided that the
Company is not required to preserve any such right, license or franchise, or the
existence of any Restricted Subsidiary, if in the Company's judgment the
maintenance or preservation thereof is no longer desirable in the conduct of the
business of the Company and its Restricted Subsidiaries taken as a whole; and
provided further that this Section does not prohibit any transaction otherwise
permitted by Section 4.13 or Article 5.

                                       44
<PAGE>

         Section 4.04. Payment of Taxes and Other Claims. The Company will pay
or discharge, and cause each of its Subsidiaries to pay or discharge before the
same become delinquent (a) all material taxes, assessments and governmental
charges levied or imposed upon the Company or any Subsidiary or its income or
profits or property, and (b) all material lawful claims for labor, materials and
supplies that, if unpaid, might by law become a Lien upon the property of the
Company or any Subsidiary, other than any such tax, assessment, charge or claim
the amount, applicability or validity of which is being contested in good faith

permit any Restricted Subsidiary to, directly or indirectly, incur or permit to
exist any Lien of any nature whatsoever on any of its properties or assets,
whether owned at the Issue Date or thereafter acquired, other than Permitted
Liens, provided, however, that the foregoing will not apply to the extent the
Company or any Restricted Subsidiary effectively provides that the Notes shall
be secured equally and ratably with (or, if the obligation to be secured by the
Lien is subordinated in right of payment to the Notes or any Note Guaranty,
prior to) the obligations so secured for so long as such obligations are so
secured.

         Section 4.09. Limitation on Dividend and Other Payment Restrictions
Affecting Restricted Subsidiaries. (a) Except as provided in paragraph (b), the

Subsidiary to

                  (i)      pay dividends or make any other distributions on any

         the Indenture or any other agreements in effect on the Issue Date, and
         any extensions, renewals, replacements or refinancings of any of the
         foregoing or of any subsequent extension, renewal, replacement or
         refinancing thereof; provided that the encumbrances and restrictions in
         the extension, renewal, replacement or refinancing are, taken as a
         whole, no more adverse in any material respect to the Noteholders than

         refinanced;

                  (ii)     existing under or by reason of applicable law;

                           (B)      with respect to any Unrestricted Subsidiary
                  at the time it is designated or is deemed to become a
                  Restricted Subsidiary,

         which encumbrances or restrictions (x) are not applicable to any other
         Person or the property or assets of any other Person and (y) were not

         renewals, replacements or refinancings of any of the foregoing, or of
         any subsequent extension, renewal, replacement or refinancing thereof,
         provided the encumbrances and restrictions in the extension, renewal,
         replacement or refinancing are, taken as a whole, no more adverse in
         any material respect to the Noteholders than the encumbrances or
         restrictions being extended, renewed, replaced or refinanced;

                  (iv)     of the type described in clause (a)(iv) arising or

                  the agreements under which such interest is owned or
                  maintained, including, without limitation, options, put and
                  call arrangements, rights of first refusal and similar rights,
                  provided that such restrictions are consistent with the
                  Company's past practice, or

                                       54
<PAGE>

                           (C)      by virtue of any Permitted Lien on, or
                  agreement to transfer, option or similar right with respect
                  to, any property or assets of, the Company or any Restricted
                  Subsidiary;

                  (v)      with respect to a Restricted Subsidiary and imposed
         pursuant to an agreement that has been entered into for the sale or

         (ii), (iii) or (iv) provided for by any credit agreement or security
         document relating to Debt permitted to be incurred under the Indenture;
         provided that such restrictions are not more restrictive than the
         restrictions contained in the Indenture or the Credit Agreement;

                  (vii)    required pursuant to Section 4.06(b)(ii);

                  (viii)   imposed on any Joint Venture pursuant to customary
         limitations contained in the constituent documents and agreements

         document relating to Debt incurred pursuant to clause (b)(x) or (b)(xi)
         under Section 4.06 or Permitted Refinancing Debt in respect thereof;
         provided that (a) such restrictions apply only to the Persons Incurring
         such Debt (including Guarantees thereof) and their Subsidiaries and (b)
         such Debt is not Guaranteed by the Company.

         Section 4.10. Limitation on Sale or Issuance of Equity Interests of
Restricted Subsidiaries. The Company will not, and will not permit any
Restricted Subsidiary to, directly or indirectly, sell or issue any Equity
Interests of a Restricted Subsidiary unless

         Owned Restricted Subsidiary,

                  (b)      the sale or issuance is of Capital Stock representing
         directors' qualifying shares or Capital Stock required by applicable
         law to be held by a Person other than the Company or a Restricted
         Subsidiary,

                  (c)      (i) if, after giving pro forma effect to the sale or
         issuance, the Restricted Subsidiary upon such sale or issuance would no
         longer be a Restricted Subsidiary and all remaining Investments, if
         any, of the Company and the Restricted Subsidiaries in such Person are
         permitted

                                       55
<PAGE>

         under Section 4.07 and (ii) the Company complies with Section 4.13 with
         respect to the sale or issuance, to the extent applicable;

                  (d)      (i) such sale or issuance is a sale or issuance of
         Common Stock of a Restricted Subsidiary that is a Guarantor and remains
         a Restricted Subsidiary that is a Guarantor after giving effect to the
         sale, and (ii) the Company complies with Section 4.13 with respect to
         the sale or issuance, to the extent applicable; or

         Disqualified Stock permitted under Section 4.06.

         Section 4.11. Guaranties by Restricted Subsidiaries. If the Company or
any of its Restricted Subsidiaries acquires or creates a Domestic Restricted
Subsidiary (other than any Foreign-Owned Parent Holding Company) after the Issue
Date, the new Domestic Restricted Subsidiary must provide a Note Guaranty until
such Guaranty is released pursuant to Section 10.09. In addition, from and after
the repayment date, Century Aluminum of Kentucky LLC must provide a Note
Guaranty until such guaranty is released pursuant to Section 10.09.

         A Restricted Subsidiary required to provide a Note Guaranty shall
execute a supplemental indenture substantially in the form of Exhibit B, and
deliver an Opinion of Counsel to the Trustee to the effect that the supplemental
indenture has been duly authorized, executed and delivered by the Restricted
Subsidiary and constitutes a valid and binding obligation of the Restricted
Subsidiary, enforceable against the Restricted Subsidiary in accordance with its
terms (subject to customary exceptions).

         Section 4.12. Repurchase of Notes upon a Change of Control. Not later
than 30 days following a Change of Control, the Company will make an Offer to

         (a)      The Asset Sale is for fair market value, as determined in good
faith by the Board of Directors.

         (b)      At least 75% of the consideration consists of cash received at
closing.

         For purposes of this clause (b):

                                       56
<PAGE>

                  (i)      Debt (other than Subordinated Debt) or other
         obligations of the Company or a Restricted Subsidiary assumed by the
         purchaser pursuant to a customary novation agreement, and

                  (ii)     instruments or securities received from the purchaser
         that are promptly, but in any event within 30 days of the closing,
         converted by the Company to cash, to the extent of the cash actually so
         received shall be considered cash received at closing.

         (c)      An amount equal to the Net Cash Proceeds from the Asset Sale
may be used

                  (i)      to permanently repay Debt under the Credit Agreement,
         secured Debt of the Company or any Guarantor or Debt of any Restricted
         Subsidiary that is not a Guarantor (and in the case of a revolving
         credit, permanently reduce the commitment thereunder by such amount),
         or

                  (ii)     to acquire all or substantially all of the assets of
         a Permitted Business, or a majority of the Voting Stock of another
         Person that thereupon becomes a Restricted Subsidiary engaged in a
         Permitted Business, or to make capital expenditures or otherwise
         acquire long-term assets (including an undivided interest therein) that
         are to be used in a Permitted Business.

         (d)      The Net Cash Proceeds of an Asset Sale not applied pursuant to
clause (c) within 360 days of the Asset Sale constitute "EXCESS PROCEEDS".
Excess Proceeds of less than $10.0 million will be carried forward and
accumulated. When accumulated Excess Proceeds equal or exceed $10.0 million, the
Company must, within 30 days, make an Offer to Purchase Notes having a principal
amount equal to

                  (i)      accumulated Excess Proceeds, multiplied by

                  (ii)     a fraction (x) the numerator of which is equal to the
         outstanding principal amount of the Notes and (y) the denominator of
         which is equal to the outstanding principal amount of the Notes and all
         pari passu Debt similarly required to be repaid, redeemed or tendered
         for in connection with the Asset Sale,

rounded down to the nearest $1,000. The purchase price for the Notes will be
100% of the principal amount plus accrued interest to the date of purchase. Upon
completion of the Offer to Purchase, Excess Proceeds will be reset at zero, and
any Excess Proceeds remaining after consummation of the Offer to Purchase may be
used for any purpose not otherwise prohibited by the Indenture.

         Section 4.14. Limitation on Transactions with Shareholders and
Affiliates. (a) The Company will not, and will not permit any Restricted
Subsidiary to, directly or indirectly, enter into, renew or extend any
transaction or arrangement (including, without limitation, the purchase, sale,
lease or exchange of property or assets, or the rendering of any service) with
(x) any holder, or any Affiliate of any holder, of 5% or more of any class of
Capital Stock of the Company or (y) any Affiliate of the Company or any
Restricted Subsidiary (a "RELATED PARTY TRANSACTION"), except upon fair and
reasonable terms no less favorable to the Company or the Restricted Subsidiary
than could be obtained in a comparable arm's-length transaction with a Person
that is not an Affiliate of the Company.

         (b)      Any Related Party Transaction or series of Related Party
Transactions with an aggregate value in excess of $5.0 million must first be
approved by a majority of the members of the Board of Directors who are
disinterested in the subject matter of the transaction (the "DISINTERESTED
DIRECTORS") pursuant to a Board Resolution delivered to the Trustee. Prior to
entering into any Related Party Transaction or series of Related Party
Transactions with an aggregate value in excess of $25.0 million, the Company
must in addition obtain and deliver to the Trustee a favorable written opinion
from an investment banking, valuation or appraisal firm as to the fairness of
the consideration to be received or paid by the Company and its Restricted
Subsidiaries from a financial point of view. In the event of any Related Party
Transaction that consists of any asset acquisition or disposition and a related
purchase or supply agreement, the transaction shall be considered as a whole in
determining its compliance with this covenant.

         The foregoing paragraphs do not apply to

                  (i)      any transaction between the Company and any of its
         Restricted Subsidiaries or between Restricted Subsidiaries of the
         Company;

                  (ii)     the payment of reasonable and customary regular fees
         to directors of the Company who are not employees of the Company;

                  (iii)    any Restricted Payments of a type described in
         Section 4.07(a)(i) and (ii) if permitted by that covenant;

                  (iv)     transactions or payments pursuant to any employee,
         officer or director compensation or benefit plans or arrangements
         entered into in the ordinary course of business;

                  (v)      the entering into of Hedging Agreements or similar
         arrangements with Glencore or any of its Affiliates, or any amendment,

                                       58
<PAGE>

         modification, replacement, settlement or termination thereof, on a
         basis consistent with past practice and upon fair and reasonable terms
         no less favorable in any material respect to the Company or the
         Restricted Subsidiary than could reasonably be expected to be obtained
         in a comparable arms'-length transaction;

                  (vi)     agreements or arrangements with Glencore or any of
         its Affiliates relating to the procurement or sale of raw materials or
         aluminum products or the tolling of alumina; provided that such
         transactions are upon fair and reasonable terms no less favorable in
         any material respect to the Company or the Restricted Subsidiary than
         could reasonably be expected to be obtained in a comparable
         arms'-length transaction;

                  (vii)    (A) the issuance and sale of Qualified Equity
         Interests of the Company and (B) the sale to any Affiliate of the
         Company of any securities of the Company offered and sold in a broadly
         distributed underwritten offering (whether registered or pursuant to
         Rule 144A or Regulation S); provided that such sale is at a price to
         the Company no lower than the price paid to the Company with respect to
         other securities sold in such offering;

                  (viii)   agreements or arrangements with any Person that owns
         the Gramercy alumina facility or the Jamaican bauxite mining operations
         on the terms described in the Offering Circular under "The Planned
         Gramercy Acquisition", in each case as amended, modified or replaced
         from time to time, including any subsequent replacements, so long as
         the amended, modified or new agreement or arrangement, taken as a
         whole, is not materially less favorable to the Company and its
         Restricted Subsidiaries than the agreements amended, modified or
         replaced;

                  (ix)     transactions between the Company or any Restricted
         Subsidiary and any Joint Venture or Unrestricted Subsidiary of the
         Company entered into in the ordinary course of business; provided that
         such transactions are upon fair and reasonable terms not materially
         less favorable to the Company or the Restricted Subsidiary than could
         be obtained in a comparable arms'-length transaction and are approved
         by the Board of Directors; and

                  (x)      transactions pursuant to any contract or agreement in
         effect on the Issue Date, in each case as amended, modified or
         replaced, from time to time, including any subsequent replacements, so
         long as the amended, modified or new agreement, taken as a whole, is
         not materially less favorable to the Company and its Restricted
         Subsidiaries than those in effect on the Issue Date.

         Section 4.15. Line of Business. The Company will not, and will not
permit any of its Restricted Subsidiaries, to engage in any business other than
a Permitted Business (including indirectly, through its interest in a Joint
Venture that is not a Restricted Subsidiary), except to an extent that so doing
would not be material to the Company and its Restricted Subsidiaries, taken as a
whole.

         Section 4.16. Designation of Restricted and Unrestricted Subsidiaries.
(a) The Board of Directors may designate any Subsidiary, including a newly
acquired or created Subsidiary, to be an Unrestricted Subsidiary if it meets the
following qualifications and the designation would not cause a Default.

                  (i)      Such Subsidiary does not own any Capital Stock of the
         Company or any Restricted Subsidiary or hold any Debt of, or any Lien
         on any property of, the Company or any Restricted Subsidiary.

                  (ii)     At the time of designation, the designation would be
         permitted under Section 4.07.

                  (iii)    To the extent the Debt of the Subsidiary is not
         Non-Recourse Debt, any Guarantee or other credit support thereof by the
         Company or any Restricted Subsidiary is permitted under Section 4.06
         and Section 4.07.

                  (iv)     The Subsidiary is not party to any transaction or
         arrangement with the Company or any Restricted Subsidiary that would
         not be permitted under Section 4.14.

                  (v)      Neither the Company nor any Restricted Subsidiary has
         any obligation to subscribe for additional Equity Interests of the
         Subsidiary or to maintain or preserve its financial condition or cause
         it to achieve specified levels of operating results except to the
         extent permitted by Section 4.06 and Section 4.07.

Once so designated the Subsidiary will remain an Unrestricted Subsidiary,
subject to paragraph (b).

         (b)      (i) A Subsidiary previously designated an Unrestricted
Subsidiary which at any time fails to meet the qualifications set forth in
paragraph (a) will be deemed to become at that time a Restricted Subsidiary,
subject to the consequences set forth in paragraph (d).

                  (ii)     The Board of Directors may designate an Unrestricted
         Subsidiary to be a Restricted Subsidiary if the designation would not
         cause a Default.

         (c)      Upon a Restricted Subsidiary becoming an Unrestricted
Subsidiary,

                                       60
<PAGE>

                  (i)      all existing Investments of the Company and the
         Restricted Subsidiaries therein will be deemed made at that time;

                  (ii)     all existing transactions between it and the Company
         or any Restricted Subsidiary will be deemed entered into at that time;

                  (iii)    it will be released at that time from its Note
         Guaranty, if any; and

                  (iv)     it will cease to be subject to the provisions of the
         Indenture as a Restricted Subsidiary.

         (d)      Upon an Unrestricted Subsidiary becoming, or being deemed to
become, a Restricted Subsidiary,

                  (i)      all of its Debt and Disqualified or Preferred Stock
         will be deemed Incurred at that time for purposes of Section 4.06 but
         will not be considered the sale or issuance of Equity Interests for
         purposes of Section 4.10 or Section 4.13;

                  (ii)     Investments therein previously charged under Section
         4.07 will be credited thereunder;

                  (iii)    it may be required to issue a Note Guaranty of the
         Notes pursuant to Section 4.11; and

<PAGE>

         pursuant to Section 4.12 or Section 4.13, or the Company or any
         Guarantor fails to comply with Article 5;

                  (e)      there occurs with respect to any Debt of the Company

         of money are rendered against the Company or any of its Restricted
         Subsidiaries and are not paid or discharged, and there is a period of
         60 consecutive days following entry of the final judgment or order that
         causes the aggregate amount for all such final judgments or orders
         outstanding and not paid or discharged against all such Persons to
         exceed $10.0 million (in excess of amounts which the Company's
         insurance carriers have agreed to pay under applicable policies) during
         which a stay of enforcement, by reason of a pending appeal or
         otherwise, is not in effect (a "JUDGMENT DEFAULT");

                  (g)      an involuntary case or other proceeding is commenced
         against the Company or any Significant Restricted Subsidiary with
         respect to it or its debts under any bankruptcy, insolvency or other
         similar law now or hereafter in effect seeking the appointment of a
         trustee, receiver, liquidator, custodian or other similar official of

<PAGE>

         official of the Company or any of its Significant Restricted
         Subsidiaries or for all or substantially all of the property and assets
         of the Company or any of its Significant Restricted Subsidiaries or
         (iii) effects any general assignment for the benefit of creditors (an
         event of default specified in clause (g) or (h) a "BANKRUPTCY
         DEFAULT"); or

                  (i)      any Note Guaranty of any Significant Restricted
         Subsidiary ceases to be in full force and effect, other than in
         accordance with the terms of the Indenture, or any such Guarantor
         denies or disaffirms its obligations under its Note Guaranty.

         Section 6.02. Acceleration. (a) If an Event of Default, other than a
bankruptcy default with respect to the Company, occurs and is continuing under
the Indenture, the Trustee or the Holders of at least 25% in aggregate principal
amount of the Notes then outstanding, by written notice to the Company (and to
the Trustee if the notice is given by the Holders), may, and the Trustee at the
request of such Holders shall, declare the principal of and accrued interest on
the Notes to be immediately due and payable. Upon a declaration of acceleration,
such principal and interest will become immediately due and payable. If a
bankruptcy default occurs with respect to the Company, the principal of and
accrued interest on the Notes then outstanding will become immediately due and
payable without any declaration or other act on the part of the Trustee or any
Holder.

         (b)      The Holders of a majority in principal amount of the
outstanding Notes by written notice to the Company and to the Trustee may waive
all past defaults and rescind and annul a declaration of acceleration and its
consequences if

                  (i)      all existing Events of Default, other than the
         nonpayment of the principal of, premium, if any, and interest on the
         Notes that have become due solely by the declaration of acceleration,
         have been cured or waived, and

                  (ii)     the rescission would not conflict with any judgment
         or decree of a court of competent jurisdiction.

         Section 6.03. Other Remedies. If an Event of Default occurs and is
continuing, the Trustee may pursue, in its own name or as trustee of an express
trust any available remedy by proceeding at law or in equity to collect the
payment of principal of and interest on the Notes or to enforce the performance
of any provision of the Notes or the Indenture, and any recovery of judgment
shall be for the ratable benefit of the Holders of the Notes. The Trustee may
maintain a proceeding even if it does not possess any of the Notes or does not
produce any of them in the proceeding.

                                       67
<PAGE>

         Section 6.04. Waiver of Past Defaults. Except as otherwise provided in
Sections 6.02, 6.07 and 9.02, the Holders of a majority in principal amount of
the outstanding Notes may, by notice to the Trustee, waive an existing Default
and its consequences. Upon such waiver, the Default will cease to exist, and any
Event of Default arising therefrom will be deemed to have been cured, but no
such waiver will extend to any subsequent or other Default or impair any right
consequent thereon.

         Section 6.05. Control by Majority. The Holders of a majority in
aggregate principal amount of the outstanding Notes may direct the time, method
and place of conducting any proceeding for any remedy available to the Trustee
or exercising any trust or power conferred on the Trustee. However, the Trustee
may refuse to follow any direction that conflicts with law or the Indenture,
that may involve the Trustee in personal liability, or that the Trustee
determines in good faith may be unduly prejudicial to the rights of Holders of
Notes not joining in the giving of such direction, and may take any other action
it deems proper that is not inconsistent with any such direction received from
Holders of Notes.

         Section 6.06. Limitation on Suits. A Holder may not institute any
proceeding, judicial or otherwise, with respect to the Indenture or the Notes,
or for the appointment of a receiver or trustee, or for any other remedy under
the Indenture or the Notes, unless:

                  (a)      the Holder has previously given to the Trustee
         written notice of a continuing Event of Default;

                  (b)      Holders of at least 25% in aggregate principal amount
         of outstanding Notes have made written request to the Trustee to
         institute proceedings in respect of the Event of Default in its own
         name as Trustee under the Indenture;

                  (c)      Holders have offered to the Trustee indemnity
         reasonably satisfactory to the Trustee against any costs, liabilities
         or expenses to be incurred in compliance with such request;

                  (d)      the Trustee for 60 days after its receipt of such
         notice, request and offer of indemnity has failed to institute any such
         proceeding; and

                  (e)      during such 60-day period, the Holders of a majority
         in aggregate principal amount of the outstanding Notes have not given
         the Trustee a direction that is inconsistent with such written request.

         Section 6.07. Rights of Holders to Receive Payment. Notwithstanding
anything to the contrary, the right of a Holder of a Note to receive payment of

                                       68
<PAGE>

principal of or interest on its Note on or after the Stated Maturities thereof,
or to bring suit for the enforcement of any such payment on or after such
respective dates, may not be impaired or affected without the consent of that
Holder.

         Section 6.08. Collection Suit by Trustee. If an Event of Default in
payment of principal or interest specified in clause (1) or (2) of Section 6.01
occurs and is continuing, the Trustee may recover judgment in its own name and
as trustee of an express trust for the whole amount of principal and accrued
interest remaining unpaid, together with interest on overdue principal and,
overdue installments of interest, in each case at the rate specified in the
Notes, and such further amount as is sufficient to cover the costs and expenses
of collection, including the reasonable compensation, expenses, disbursements
and advances of the Trustee, its agents and counsel and any other amounts due
the Trustee hereunder.

         Section 6.09. Trustee May File Proofs of Claim. The Trustee may file
proofs of claim and other papers or documents as may be necessary or advisable
in order to have the claims of the Trustee (including any claim for the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel, and any other amounts due the Trustee hereunder) and the
Holders allowed in any judicial proceedings relating to the Company or any
Guarantor or their respective creditors or property, and is entitled and
empowered to collect, receive and distribute any money, securities or other
property payable or deliverable upon conversion or exchange of the Notes or upon
any such claims. Any custodian, receiver, assignee, trustee, liquidator,
sequestrator or other similar official in any such judicial proceeding is hereby
authorized by each Holder to make such payments to the Trustee and, if the
Trustee consents to the making of such payments directly to the Holders, to pay
to the Trustee any amount due to it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agent and counsel, and any other
amounts due the Trustee hereunder. Nothing in the Indenture will be deemed to
empower the Trustee to authorize or consent to, or accept or adopt on behalf of
any Holder, any plan of reorganization, arrangement, adjustment or composition
affecting the Notes or the rights of any Holder thereof, or to authorize the
Trustee to vote in respect of the claim of any Holder in any such proceeding.

         Section 6.10. Priorities. If the Trustee collects any money pursuant to
this Article, it shall pay out the money in the following order:

                  First: to the Trustee for all amounts due hereunder;

                  Second: to Holders for amounts then due and unpaid for
         principal of and interest on the Notes, ratably, without preference or
         priority of any kind, according to the amounts due and payable on the
         Notes for principal and interest; and

                                       69
<PAGE>

                  Third: to the Company or relevant Guarantor or as a court of
         competent jurisdiction may direct.

         The Trustee, upon written notice to the Company, may fix a record date
and payment date for any payment to Holders pursuant to this Section.

         Section 6.11. Restoration of Rights and Remedies. If the Trustee or any
Holder has instituted a proceeding to enforce any right or remedy under the
Indenture and the proceeding has been discontinued or abandoned for any reason,
or has been determined adversely to the Trustee or to the Holder, then, subject
to any determination in the proceeding, the Company, any Guarantors, the Trustee
and the Holders will be restored severally and respectively to their former
positions hereunder and thereafter all rights and remedies of the Company, any
Guarantors, the Trustee and the Holders will continue as though no such
proceeding had been instituted.

         Section 6.12. Undertaking for Costs. In any suit for the enforcement of
any right or remedy under the Indenture or in any suit against the Trustee for
any action taken or omitted by it as Trustee, a court may require any party
litigant in such suit (other than the Trustee) to file an undertaking to pay the
costs of the suit in the manner and to the extent provided in the Trust
Indenture Act, and the court may assess reasonable costs, including reasonable
attorneys fees, against any party litigant (other than the Trustee) in the suit
having due regard to the merits and good faith of the claims or defenses made by
the party litigant. This Section does not apply to a suit by a Holder to enforce
payment of principal of or interest on any Note on the respective due dates, or
a suit by Holders of more than 10% in principal amount of the outstanding Notes.

         Section 6.13. Rights and Remedies Cumulative. No right or remedy
conferred or reserved to the Trustee or to the Holders under this Indenture is
intended to be exclusive of any other right or remedy, and all such rights and
remedies are, to the extent permitted by law, cumulative and in addition to
every other right and remedy hereunder or now or hereafter existing at law or in
equity or otherwise. The assertion or exercise of any right or remedy hereunder,
or otherwise, will not prevent the concurrent assertion or exercise of any other
right or remedy.

         Section 6.14. Delay or Omission Not Waiver. No delay or omission of the
Trustee or of any Holder to exercise any right or remedy accruing upon any Event
of Default will impair any such right or remedy or constitute a waiver of any
such Event of Default or an acquiescence therein. Every right and remedy given
by this Article or by law to the Trustee or to the Holders may be exercised from
time to time, and as often as may be deemed expedient, by the Trustee or by the
Holders, as the case may be.

         Section 6.15. Waiver of Stay, Extension or Usury Laws. The Company and
each Guarantor covenants, to the extent that it may lawfully do so, that it will
not at any time insist upon, or plead, or in any manner whatsoever claim or take
the benefit or advantage of, any stay or extension law or any usury law or other
law that would prohibit or forgive the Company or the Guarantor from paying all
or any portion of the principal of, or interest on the Notes as contemplated
herein, wherever enacted, now or at any time hereafter in force, or that may
affect the covenants or the performance of the Indenture. The Company and each
Guarantor hereby expressly waives, to the extent that it may lawfully do so, all
benefit or advantage of any such law and covenants that it will not hinder,
delay or impede the execution of any power herein granted to the Trustee, but
will suffer and permit the execution of every such power as though no such law
had been enacted.

                                    ARTICLE 7
                                   THE TRUSTEE

         Section 7.01. General. (a) The duties and responsibilities of the
Trustee are as provided by the Trust Indenture Act and as set forth herein.
Whether or not expressly so provided, every provision of the Indenture relating
to the conduct or affecting the liability of or affording protection to the
Trustee is subject to this Article.

         (b)      Except during the continuance of an Event of Default, the
Trustee need perform only those duties that are specifically set forth in the
Indenture and no others, and no implied covenants or obligations will be read
into the Indenture against the Trustee. In case an Event of Default has occurred
and is continuing, the Trustee shall exercise those rights and powers vested in
it by the Indenture, and use the same degree of care and skill in their
exercise, as a prudent man would exercise or use under the circumstances in the
conduct of his own affairs.

         (c)      No provision of the Indenture shall be construed to relieve
the Trustee from liability for its own negligent action, its own negligent
failure to act or its own willful misconduct.

         Section 7.02. Certain Rights of Trustee. Subject to Trust Indenture Act
Sections 315(a) through (d):

                  (a)      In the absence of bad faith on its part, the Trustee
         may rely, and will be protected in acting or refraining from acting,
         upon any resolution, certificate, statement, instrument, opinion,
         report, notice, request, direction, consent, order, bond, debenture,
         note, other evidence of indebtedness or other paper or document
         believed by it to be genuine and to have been signed or presented by
         the proper Person. The Trustee need

                                       71
<PAGE>

         not investigate any fact or matter stated in any such document, but, in
         the case of any document which is specifically required to be furnished
         to the Trustee pursuant to any provision hereof, the Trustee shall
         examine the document to determine whether it conforms to the
         requirements of the Indenture (but need not confirm or investigate the
         accuracy of mathematical calculations or other facts stated therein).
         The Trustee, in its discretion, may make further inquiry or
         investigation into such facts or matters as it sees fit.

                  (b)      Before the Trustee acts or refrains from acting, it
         may require an Officers' Certificate or an Opinion of Counsel
         conforming to Section 11.05 and the Trustee will not be liable for any
         action it takes or omits to take in good faith in reliance on the
         certificate or opinion.

                  (c)      The Trustee may act through its attorneys and agents
         and will not be responsible for the misconduct or negligence of any
         agent appointed with due care.

                  (d)      The Trustee will be under no obligation to exercise
         any of the rights or powers vested in it by the Indenture at the
         request or direction of any of the Holders, unless such Holders have
         offered to the Trustee reasonable security or indemnity against the
         costs, expenses and liabilities that might be incurred by it in
         compliance with such request or direction.

                  (e)      The Trustee will not be liable for any action it
         takes or omits to take in good faith that it believes to be authorized
         or within its rights or powers or for any action it takes or omits to
         take in accordance with the direction of the Holders in accordance with
         Section 6.05 relating to the time, method and place of conducting any
         proceeding for any remedy available to the Trustee, or exercising any
         trust or power conferred upon the Trustee, under the Indenture.

                  (f)      The Trustee may consult with counsel, and the written
         advice of such counsel or any Opinion of Counsel will be full and
         complete authorization and protection in respect of any action taken,
         suffered or omitted by it hereunder in good faith and in reliance
         thereon.

                  (g)      No provision of the Indenture will require the
         Trustee to expend or risk its own funds or otherwise incur any
         financial liability in the performance of its duties hereunder, or in
         the exercise of its rights or powers, unless it receives indemnity
         satisfactory to it against any loss, liability or expense.

                  (h)      The Trustee shall not be charged with knowledge of
         any Default or Event of Default with respect to the Notes unless either
         (i) a

                                       72
<PAGE>

         Responsible Officer of the Trustee shall have actual knowledge thereof
         or (ii) a written notice of such Default or Event of Default shall have
         been given to the Trustee by the Company or any Holder of Notes.

                  (i)      The permissive rights of the Trustee to take actions
         enumerated in this Indenture shall not be construed as a duty, and the
         Trustee shall not be answerable for other than its negligence or
         willful misconduct with respect to such permissive rights.

         Section 7.03. Individual Rights of Trustee. The Trustee, in its
individual or any other capacity, may become the owner or pledgee of Notes and
may otherwise deal with the Company or its Affiliates with the same rights it
would have if it were not the Trustee. Any Agent may do the same with like
rights. However, the Trustee is subject to Trust Indenture Act Sections 310(b)
and 311. For purposes of Trust Indenture Act Section 311(b)(4) and (6):

                  (a)      "CASH TRANSACTION" means any transaction in which
         full payment for goods or securities sold is made within seven days
         after delivery of the goods or securities in currency or in checks or
         other orders drawn upon banks or bankers and payable upon demand; and

                  (b)      "SELF-LIQUIDATING PAPER" means any draft, bill of
         exchange, acceptance or obligation which is made, drawn, negotiated or
         incurred for the purpose of financing the purchase, processing,
         manufacturing, shipment, storage or sale of goods, wares or merchandise
         and which is secured by documents evidencing title to, possession of,
         or a lien upon, the goods, wares or merchandise or the receivables or
         proceeds arising from the sale of the goods, wares or merchandise
         previously constituting the security, provided the security is received
         by the Trustee simultaneously with the creation of the creditor
         relationship arising from the making, drawing, negotiating or incurring
         of the draft, bill of exchange, acceptance or obligation.

         Section 7.04. Trustee's Disclaimer. The Trustee (a) makes no
representation as to the validity or adequacy of the Indenture or the Notes, (b)
is not accountable for the Company's use or application of the proceeds from the
Notes and (c) is not responsible for any statement in the Notes other than its
certificate of authentication.

         Section 7.05. Notice of Default. If any Default occurs and is
continuing and is known to the Trustee, the Trustee will send notice of the
Default to each Holder within 90 days after it occurs, unless the Default has
been cured; provided that, except in the case of a default in the payment of the
principal of or interest on any Note, the Trustee may withhold the notice if and
so long as the board of directors, the executive committee or a trust committee
of directors of the Trustee

                                       73
<PAGE>

in good faith determines that withholding the notice is in the interest of the
Holders. Notice to Holders under this Section will be given in the manner and to
the extent provided in Trust Indenture Act Section 313(c).

         Section 7.06. Reports by Trustee to Holders. Within 60 days after each
May 15, beginning with May 15, 2005, the Trustee will mail to each Holder, as
provided in Trust Indenture Act Section 313(c) a brief report dated as of such
May 15, if required by Trust Indenture Act Section 313(a). The Trustee will also
mail to each Holder any report required by Trust Indenture Act Section 313(b).

         Section 7.07. Compensation and Indemnity. (a) The Company will pay the
Trustee compensation as agreed upon in writing for its services. The
compensation of the Trustee is not limited by any law on compensation of a
Trustee of an express trust. The Company will reimburse the Trustee upon request
for all reasonable and documented out-of-pocket expenses, disbursements and
advances incurred or made by the Trustee, including the reasonable compensation
and expenses of the Trustee's agents and counsel.

         (b)      The Company will indemnify the Trustee for, and hold it
harmless against, any loss or liability or expense incurred by it without
negligence or bad faith on its part arising out of or in connection with the
acceptance or administration of the Indenture and its duties under the Indenture
and the Notes, including the reasonable costs and expenses of defending itself
against any claim or liability and of complying with any process served upon it
or any of its officers in connection with the exercise or performance of any of
its powers or duties under the Indenture and the Notes. The Trustee shall
promptly notify the Company of any claim for which it may seek indemnity. The
Company shall defend the claim, and the Trustee shall cooperate in the defense
thereof. The Company shall have no obligation to pay for any settlement of any
such claim without its consent, which consent shall not be unreasonably
withheld.

         (c)      To secure the Company's payment obligations in this Section,
the Trustee will have a lien prior to the Notes on all money or property held or
collected by the Trustee, in its capacity as Trustee, except money or property
held in trust to pay principal of, and interest on particular Notes.

         (d)      When the Trustee incurs expenses or renders services after an
Event of Default specified in clause (g) or (h) of Section 6.01 occurs, the
expenses and the compensation for the services are intended to constitute
expenses of administration to the extent permitted by law under apply applicable
bankruptcy, reorganization, insolvency or other similar law not or hereinafter
in effect.

         The obligations of the Company under this Section 7.07 shall survive
the satisfaction and discharge of this Indenture or the resignation or removal
of the Trustee.

any time by written notice to the Company.

                  (i)      The Holders of a majority in principal amount of the
         outstanding Notes may remove the Trustee by written notice to the
         Trustee.

                  (ii)     If the Trustee is no longer eligible under Section
         7.10 or in the circumstances described in Trust Indenture Act Section
         310(b) any Holder that satisfies the requirements of Trust Indenture
         Act Section 310(b). may petition any court of competent jurisdiction
         for the removal of the Trustee and the appointment of a successor
         Trustee.

         Trustee is no longer eligible under Section 7.10; (B) the Trustee is
         adjudged a bankrupt or an insolvent; (C) a receiver or other public
         officer takes charge of the Trustee or its property; or (D) the Trustee
         becomes incapable of acting.

A resignation or removal of the Trustee and appointment of a successor Trustee
will become effective only upon the successor Trustee's acceptance of
appointment as provided in this Section.

         (b)      If the Trustee has been removed by the Holders, Holders of a
majority in principal amount of the Notes may appoint a successor Trustee with
the consent of the Company. Otherwise, if the Trustee resigns or is removed, or
if a vacancy exists in the office of Trustee for any reason, the Company will
promptly appoint a successor Trustee. If the successor Trustee does not deliver
its written acceptance within 30 days after the retiring Trustee resigns or is
removed, the retiring Trustee, the Company or the Holders of a majority in
principal amount of the outstanding Notes may petition any court of competent
jurisdiction for the appointment of a successor Trustee.

         (c)      Upon delivery by the successor Trustee of a written acceptance

Trustee, subject to the lien provided for in Section 7.07, (ii) the resignation
or removal of the retiring Trustee will become effective, and (iii) the
successor Trustee will have all the rights, powers and duties of the Trustee
under the Indenture. Upon request of any successor Trustee, the Company will

successor Trustee all such rights, powers and trusts. The Company will give
notice of any resignation and any removal of the Trustee and each appointment of
a successor Trustee to all Holders, and include in the notice the name of the
successor Trustee and the address of its Corporate Trust Office.

         (d)      Notwithstanding replacement of the Trustee pursuant to this
Section, the Company's obligations under Section 7.07 will continue for the
benefit of the retiring Trustee.

         (e)      The Trustee agrees to give the notices provided for in, and
otherwise comply with, Trust Indenture Act Section 310(b).

         Section 7.09. Successor Trustee by Merger. If the Trustee consolidates
with, merges or converts into, or transfers all or substantially all of its
corporate trust business to, another corporation or national banking
association, the resulting, surviving or transferee corporation or national
banking association without any further act will be the successor Trustee with
the same effect as if the successor Trustee had been named as the Trustee in the
Indenture.

         Section 7.10. Eligibility. The Indenture must always have a Trustee
that satisfies the requirements of Trust Indenture Act Section 310(a) and has a
combined capital and surplus of at least $100,000,000 as set forth in its most
recent published annual report of condition.

         Section 7.11. Money Held in Trust. The Trustee will not be liable for

         whose payment money or U.S. Government Obligations have been held in

         all sums payable by it hereunder; or

                  (ii)     (A) the Notes mature within one year, or all of them
         are to be called for redemption within one year under arrangements
         satisfactory to the Trustee for giving the notice of redemption,

                  with the Trustee, as trust funds solely for the benefit of the
                  Holders, money or U.S. Government Obligations or a combination
                  thereof sufficient, in the opinion of a nationally recognized
                  firm of independent public accountants expressed in a written
                  certificate delivered to the Trustee, without consideration of
                  any reinvestment, to pay principal of and interest on the

                  relating to the satisfaction and discharge of the Indenture
                  have been complied with.

         (b)      After satisfying the conditions in clause (i), only the
Company's obligations under Section 7.07 will survive. After satisfying the
conditions in clause (ii), only the Company's obligations in Article 2 and
Sections 4.01, 4.02, 7.07, 7.08, 8.05 and 8.06 will survive. In either case, the
Trustee upon request will acknowledge in writing the discharge of the Company's

         Section 8.02. Legal Defeasance. After the 123rd day following the
deposit referred to in clause (a) below, the Company will be deemed to have paid

         independent public accountants expressed in a written certificate
         thereof delivered to the Trustee, without consideration of any
         reinvestment, to pay principal of and interest on the Notes to maturity
         or redemption, as the case may be, provided that any

                                       77
<PAGE>

         redemption before maturity has been irrevocably provided for under
         arrangements satisfactory to the Trustee.

                  (b)      No Default has occurred and is continuing on the date

         following the deposit.

                  (c)      The deposit will not result in a breach or violation
         of, or constitute a default under, the Indenture or any other agreement
         or instrument to which the Company is a party or by which it is bound.

                  (d)      The Company has delivered to the Trustee

                  not recognize income, gain or loss for federal income tax
                  purposes as a result of the defeasance and will be subject to
                  federal income tax on the same amount and in the same manner
                  and at the same times as would otherwise have been the case or
                  (y) an Opinion of Counsel, based on a change in law after the
                  date of the Indenture, to the same effect as the ruling
                  described in clause (x), and

                           (ii)     an Opinion of Counsel to the effect that (x)
                  the creation of the defeasance trust does not violate the
                  Investment Company Act of 1940, (y) the Holders have a valid
                  first priority Note interest in the trust funds (subject to
                  customary exceptions), and (z) after the passage of 123 days

         exchange, the Company has delivered to the Trustee an Opinion of
         Counsel to the effect that the deposit and defeasance will not cause
         the Notes to be delisted.

                  (f)      The Company has delivered to the Trustee an Officers'
         Certificate and an Opinion of Counsel, in each case stating that all
         conditions precedent provided for herein relating to the defeasance

obligations under the Indenture will be discharged. Thereafter, the Trustee upon
request will acknowledge in writing the discharge of the Company's obligations
under the Notes and the Indenture except for the surviving obligations specified

Section 5.02 and each Guarantor's obligations under its Note Guaranty will
terminate, and clauses (c), (d), (e), (f) and (i) of Section 6.01 will no longer
constitute Events of Default; provided the following conditions have been
satisfied:

                  (a)      The Company has complied with clauses (a), (b), (c),
         (d)(ii), (e) and (f) of Section 8.02 and

                  (b)      the Company has delivered to the Trustee an Opinion
         of Counsel to the effect that the Holders will not recognize income,
         gain or loss for federal income tax purposes as a result of the
         defeasance and will be subject to federal income tax on the same amount
         and in the same manner and at the same times as would otherwise have
         been the case.

         Upon satisfaction of the conditions described above, the Company may
omit to comply with the covenants and clauses described above and shall have no
liability in respect thereof, including by reason of any reference to such
covenants or clauses elsewhere in the Indenture. Except as specifically stated
above, none of the Company's obligations under the Indenture will be discharged.

         Section 8.04. Application of Trust Money. Subject to Section 8.05 the
Trustee will hold in trust the money or U.S. Government Obligations deposited
with it pursuant to Section 8.01, 8.02 or 8.03, and apply the deposited money
and the proceeds from deposited U.S. Government Obligations to the payment of
principal of and interest on the Notes in accordance with the Notes and the
Indenture. Such money and U.S. Government Obligations need not be segregated
from other funds except to the extent required by law.

         Section 8.05. Repayment to Company. Subject to Sections 7.07, 8.01,
8.02 and 8.03, the Trustee will promptly pay to the Company upon request any
excess money held by the Trustee at any time and thereupon be relieved from all
liability with respect to such money. The Trustee will pay to the Company upon
request any money held for payment with respect to the Notes that remains
unclaimed for two years, provided that before making such payment the Trustee
may at the expense of the Company publish once in a newspaper of general
circulation in New York City, or send to each Holder entitled to such money,
notice that the money remains unclaimed and that after a date specified in the
notice (at least 30 days after the date of the publication or notice) any
remaining unclaimed balance of money will be repaid to the Company. After
payment to the Company, Holders entitled to such money must look solely to the
Company for payment, unless applicable law designates another Person, and all
liability of the Trustee with respect to such money will cease.

         Section 8.06. Reinstatement. If and for so long as the Trustee is
unable to apply any money or U.S. Government Obligations held in trust pursuant
to Section 8.01, 8.02 or 8.03 by reason of any legal proceeding or by reason of
any order or judgment of any court or governmental authority enjoining,
restraining or otherwise prohibiting such application, the Company's obligations
under the Indenture and the Notes and the Guarantors' obligations under the
Indenture and the Note Guaranties will be reinstated as though no such deposit
in trust had been made. If the Company makes any payment of principal of or
interest on any Notes because of the reinstatement of its obligations, it will
be subrogated to the rights of the Holders of such Notes to receive such payment
from the money or U.S. Government Obligations held in trust.

                       AMENDMENTS, SUPPLEMENTS AND WAIVERS

         Section 9.01. Amendments without Consent of Holders. (a) The Company
and the Trustee may amend or supplement the Indenture and/or the Notes without
notice to or the consent of any Noteholder

                  (i)      to cure any ambiguity, defect or inconsistency in the
         Indenture or the Notes;

                  (ii)     to comply with Article 5

                  (iii)    to comply with any requirements of the Commission in
         connection with the qualification of the Indenture under the Trust
         Indenture Act;

                  (iv)     to evidence and provide for the acceptance of
         appointment hereunder by a successor Trustee;

                  (v)      to provide for uncertificated Notes in addition to or
         in place of certificated Notes, provided that the uncertified Notes are
         issued in registered form for purposes of Section 163(f) of the
         Internal Revenue Code of 1986, or in a manner such that the
         uncertificated Notes are described in Section 163(f)(2)(B) of the
         Internal Revenue Code of 1986;

                  (vi)     to provide for any Guarantee of the Notes, to provide
         security for the Notes or to confirm and evidence the release,
         termination or discharge of any Guarantee of or Lien securing the Notes
         when such release, termination or discharge is permitted by the
         Indenture; or

                  (vii)    to conform any provision to the section in the
         Offering Circular entitled "Description of the Notes".

         Section 9.02. Amendments with Consent of Holders. (a) Except as
otherwise provided in Sections 6.02, 6.04, and 6.07 or paragraph (b), the
Company and the Trustee may amend the Indenture and/or the Notes with the
written consent of the Holders of a majority in principal amount of the then
outstanding Notes, and the Holders of a majority in principal amount of the then
outstanding Notes by written notice to the Trustee may waive future compliance
by the Company with any provision of the Indenture or the Notes.

         (b)      Notwithstanding the provisions of paragraph (a), without the
consent of each Holder affected, an amendment or waiver may not

                  (i)      reduce the principal amount of or change the Stated
         Maturity of any installment of principal of any Note,

                  (ii)     reduce the rate of or change the Stated Maturity of
         any interest payment on any Note,

                  (iii)    reduce the amount payable upon the redemption of any
         Note or change the time of any mandatory redemption or, in respect of
         an optional redemption, the times at which any Note may be redeemed or,
         once notice of redemption has been given, the time at which it must
         thereupon be redeemed,

                  (iv)     after the time an Offer to Purchase is required to
         have been made, reduce the purchase amount or purchase price, or extend
         the latest expiration date or purchase date thereunder,

                  (v)      make any Note payable in money other than that stated
         in the Note,

                  (vi)     impair the right of any Holder of Notes to receive
         any principal payment or interest payment on such Holder's Notes, on or
         after the Stated Maturity thereof, or to institute suit for the
         enforcement of any such payment,

                  (vii)    make any change in the percentage of the principal
         amount of the Notes required for amendments or waivers,

                  (viii)   modify or change any provision of the Indenture
         affecting the ranking of the Notes or any Note Guaranty in a manner
         adverse to the Holders of the Notes, or

                  (ix)     except as provided in Article 10 make any change in
         any Note Guaranty that would adversely affect the Noteholders;

                                       81
<PAGE>

provided that the provisions of Section 4.12 and Section 4.13 may, except as
provided above, be amended or waived with the consent of Holders holding not
less than 66-2/3% in aggregate principal amount of the Notes.

         (c)      It is not necessary for Noteholders to approve the particular
form of any proposed amendment, supplement or waiver, but is sufficient if their
consent approves the substance thereof.

         (d)      An amendment, supplement or waiver under this Section become
effective on receipt by the Trustee of written consents from the Holders of the
requisite percentage in principal amount of the outstanding Notes. After an
amendment, supplement or waiver under this Section becomes effective, the
Company will send to the Holders affected thereby a notice briefly describing
the amendment, supplement or waiver. The Company will send supplemental
indentures to Holders upon request. Any failure of the Company to send such
notice, or any defect therein, will not, however, in any way impair or affect
the validity of any such supplemental indenture or waiver.

         Section 9.03. Effect of Consent. (a) After an amendment, supplement or
waiver becomes effective, it will bind every Holder unless it is of the type
requiring the consent of each Holder affected. If the amendment, supplement or
waiver is of the type requiring the consent of each Holder affected, the
amendment, supplement or waiver will bind each Holder that has consented to it
and every subsequent Holder of a Note that evidences the same debt as the Note
of the consenting Holder.

         (b)      If an amendment, supplement or waiver changes the terms of a
Note, the Trustee may require the Holder to deliver it to the Trustee so that
the Trustee may place an appropriate notation of the changed terms on the Note
and return it to the Holder, or exchange it for a new Note that reflects the
changed terms. The Trustee may also place an appropriate notation on any Note
thereafter authenticated. However, the effectiveness of the amendment,
supplement or waiver is not affected by any failure to annotate or exchange
Notes in this fashion.

         Section 9.04. Trustee's Rights and Obligations. The Trustee is entitled
to receive, and will be fully protected in relying upon, in addition to the
documents required by Section 11.04, an Opinion of Counsel stating that the
execution of any amendment, supplement or waiver authorized pursuant to this
Article is authorized or permitted by the Indenture. If the Trustee has received
such an Opinion of Counsel, it shall sign the amendment, supplement or waiver so
long as the same does not adversely affect the rights of the Trustee. The
Trustee may, but is not obligated to, execute any amendment, supplement or
waiver that affects the Trustee's own rights, duties or immunities under the
Indenture.

                                       82
<PAGE>

         Section 9.05. Conformity with Trust Indenture Act. Every supplemental
indenture executed pursuant to this Article shall conform to the requirements of
the Trust Indenture Act.

         Section 9.06. Payments for Consents. Neither the Company nor any of its
Subsidiaries or Affiliates may, directly or indirectly, pay or cause to be paid
any consideration, whether by way of interest, fee or otherwise, to any Holder
for or as an inducement to any consent, waiver or amendment of any of the terms
or provisions of the Indenture or the Notes unless such consideration is offered
to be paid or agreed to be paid to all Holders of the Notes that consent, waive
or agree to amend such term or provision within the time period set forth in the
solicitation documents relating to the consent, waiver or amendment.

                                   ARTICLE 10
                                   GUARANTIES

         Section 10.01. The Guaranties. Subject to the provisions of this
Article, each Guarantor hereby irrevocably and unconditionally guarantees,
jointly and severally, the full and punctual payment (whether at Stated
Maturity, upon redemption, purchase pursuant to an Offer to Purchase or
acceleration, or otherwise) of the principal of, premium, if any, and interest
on, and all other amounts payable under, each Note, and the full and punctual
payment of all other amounts payable by the Company under the Indenture. Upon
failure by the Company to pay punctually any such amount, each Guarantor shall
forthwith on demand pay the amount not so paid at the place and in the manner
specified in the Indenture.

         Section 10.02. Guaranty Unconditional. The obligations of each
Guarantor hereunder are unconditional and absolute and, without limiting the
generality of the foregoing, will not be released, discharged or otherwise
affected by

                  (a)      any extension, renewal, settlement, compromise,
         waiver or release in respect of any obligation of the Company under the
         Indenture or any Note, by operation of law or otherwise;

                  (b)      any modification or amendment of or supplement to the
         Indenture or any Note;

                  (c)      any change in the corporate existence, structure or
         ownership of the Company, or any insolvency, bankruptcy, reorganization
         or other similar proceeding affecting the Company or its assets or any
         resulting release or discharge of any obligation of the Company
         contained in the Indenture or any Note;

                                       83
<PAGE>

                  (d)      the existence of any claim, set-off or other rights
         which the Guarantor may have at any time against the Company, the
         Trustee or any other Person, whether in connection with the Indenture
         or any unrelated transactions, provided that nothing herein prevents
         the assertion of any such claim by separate suit or compulsory
         counterclaim;

                  (e)      any invalidity or unenforceability relating to or
         against the Company for any reason of the Indenture or any Note, or any
         provision of applicable law or regulation purporting to prohibit the
         payment by the Company of the principal of or interest on any Note or
         any other amount payable by the Company under the Indenture; or

                  (f)      any other act or omission to act or delay of any kind
         by the Company, the Trustee or any other Person or any other
         circumstance whatsoever which might, but for the provisions of this
         paragraph, constitute a legal or equitable discharge of or defense to
         such Guarantor's obligations hereunder.

         Section 10.03. Discharge; Reinstatement. Each Guarantor's obligations
hereunder will remain in full force and effect until the principal of, premium,
if any, and interest on the Notes and all other amounts payable by the Company
under the Indenture have been paid in full. If at any time any payment of the
principal of, premium, if any, or interest on any Note or any other amount
payable by the Company under the Indenture is rescinded or must be otherwise
restored or returned upon the insolvency, bankruptcy or reorganization of the
Company or otherwise, each Guarantor's obligations hereunder with respect to
such payment will be reinstated as though such payment had been due but not made
at such time.

         Section 10.04. Waiver by the Guarantors. Each Guarantor irrevocably
waives acceptance hereof, presentment, demand, protest and any notice not
provided for herein, as well as any requirement that at any time any action be
taken by any Person against the Company or any other Person.

         Section 10.05. Subrogation and Contribution. Upon making any payment
with respect to any obligation of the Company under this Article, the Guarantor
making such payment will be subrogated to the rights of the payee against the
Company with respect to such obligation, provided that the Guarantor may not
enforce either any right of subrogation, or any right to receive payment in the
nature of contribution, or otherwise, from any other Guarantor, with respect to
such payment so long as any amount payable by the Company hereunder, or under
the Notes remains unpaid.

         Section 10.06. Stay of Acceleration. If acceleration of the time for
payment of any amount payable by the Company under the Indenture or the Notes

                                       84
<PAGE>

is stayed upon the insolvency, bankruptcy or reorganization of the Company, all
such amounts otherwise subject to acceleration under the terms of the Indenture
are nonetheless payable by the Guarantors hereunder forthwith on demand by the
Trustee or the Holders.

         Section 10.07. Limitation on Amount of Guaranty. Notwithstanding
anything to the contrary in this Article, each Guarantor, and by its acceptance
of Notes, each Holder, hereby confirms that it is the intention of all such
parties that the Note Guaranty of such Guarantor not constitute a fraudulent
conveyance under applicable fraudulent conveyance provisions of the United
States Bankruptcy Code or any comparable provision of state law. To effectuate
that intention, the Trustee, the Holders and the Guarantors hereby irrevocably
agree that the obligations of each Guarantor under its Note Guaranty are limited
to the maximum amount that would not render the Guarantor's obligations subject
to avoidance under applicable fraudulent conveyance provisions of the United
States Bankruptcy Code or any comparable provision of state law.

         Section 10.08. Execution and Delivery of Guaranty. The execution by
each Guarantor of the Indenture (or a supplemental indenture substantially in
the form of Exhibit B) evidences the Note Guaranty of such Guarantor, whether or
not the person signing as an officer of the Guarantor still holds that office at
the time of authentication of any Note. The delivery of any Note by the Trustee
after authentication constitutes due delivery of the Note Guaranty set forth in
the Indenture on behalf of each Guarantor.

         Section 10.09. Release of Guaranty. The Note Guaranty of a Guarantor
will terminate upon

                  (a)      a sale or other disposition (including by way of
         consolidation or merger) of the Guarantor or the sale or disposition of
         all or substantially all the assets of the Guarantor (in each case
         other than to the Company or a Restricted Subsidiary) otherwise
         permitted by the Indenture,

                  (b)      the designation in accordance with the Indenture of
         the Guarantor as an Unrestricted Subsidiary, or

                  (c)      defeasance or discharge of the Notes, as provided in
         Article 8.

         Upon delivery by the Company to the Trustee of an Officers' Certificate
and an Opinion of Counsel to the foregoing effect, the Trustee will execute any
documents reasonably required in order to evidence the release of the Guarantor
from its obligations under its Note Guaranty.

                                  MISCELLANEOUS

         Section 11.01. Trust Indenture Act of 1939. The Indenture shall
incorporate and be governed by the provisions of the Trust Indenture Act that
are required to be part of and to govern indentures qualified under the Trust
Indenture Act.

         Section 11.02. Noteholder Communications; Noteholder Actions. (a) The
rights of Holders to communicate with other Holders with respect to the
Indenture or the Notes are as provided by the Trust Indenture Act, and the
Company and the Trustee shall comply with the requirements of Trust Indenture
Act Section 312(a). Neither the Company nor the Trustee will be held accountable
by reason of any disclosure of information as to names and addresses of Holders
made pursuant to the Trust Indenture Act.

         (b)      (i) Any request, demand, authorization, direction, notice,
consent to amendment, supplement or waiver or other action provided by this
Indenture to be given or taken by a Holder (an "ACT") may be evidenced by an
instrument signed by the Holder delivered to the Trustee. The fact and date of
the execution of the instrument, or the authority of the person executing it,
may be proved in any manner that the Trustee deems sufficient.

                  (ii)     The Trustee may make reasonable rules for action by
         or at a meeting of Holders, which will be binding on all the Holders.

         (c)      Any act by the Holder of any Note binds that Holder and every
subsequent Holder of a Note that evidences the same debt as the Note of the
acting Holder, even if no notation thereof appears on the Note. Subject to
paragraph (d), a Holder may revoke an act as to its Notes, but only if the
Trustee receives the notice of revocation before the date the amendment or
waiver or other consequence of the act becomes effective.

         (d)      The Company may, but is not obligated to, fix a record date
(which need not be within the time limits otherwise prescribed by Trust
Indenture Act Section 316(c)) for the purpose of determining the Holders
entitled to act with respect to any amendment or waiver or in any other regard,
except that during the continuance of an Event of Default, only the Trustee may
set a record date as to notices of default, any declaration or acceleration or
any other remedies or other consequences of the Event of Default. If a record
date is fixed, those Persons that were Holders at such record date and only
those Persons will be entitled to act, or to revoke any previous act, whether or
not those Persons continue to be Holders after the record date. No act will be
valid or effective for more than 90 days after the record date.

         Section 11.03. Notices. (a) Any notice or communication to the Company
will be deemed given if in writing (i) when delivered in person or (ii) five
days after mailing when mailed by first class mail, or (iii) when sent by
facsimile transmission, with transmission confirmed. Notices or communications
to a Guarantor will be deemed given if given to the Company. Any notice to the
Trustee will be effective only upon receipt. In each case the notice or
communication should be addressed as follows:

         if to the Company:

                  Century Aluminum Company
                  2511 Garden Road, Building A, Suite 200,
                  Monterey, CA 93940
                  Facsimile: (831) 642-9080
                  Attn: Chief Financial Officer

         if to the Trustee:

                  Wilmington Trust Company
                  Rodney Square North
                  1100 North Market Street

                  Attn: Corporate Capital Markets

The Company or the Trustee by notice to the other may designate additional or
different addresses for subsequent notices or communications.

         (b)      Except as otherwise expressly provided with respect to
published notices, any notice or communication to a Holder will be deemed given
when mailed to the Holder at its address as it appears on the Register by first
class mail or, as to any Global Note registered in the name of DTC or its
nominee, as agreed by the Company, the Trustee and DTC. Copies of any notice or
communication to a Holder, if given by the Company, will be mailed to the
Trustee at the same time. Defect in mailing a notice or communication to any
particular Holder will not affect its sufficiency with respect to other Holders.

         (c)      Where the Indenture provides for notice, the notice may be
waived in writing by the Person entitled to receive such notice, either before
or after the event, and the waiver will be the equivalent of the notice. Waivers
of notice by Holders must be filed with the Trustee, but such filing is not a
condition precedent to the validity of any action taken in reliance upon such
waivers.

Dear Sirs:

         Terms are used in this Certificate as used in Regulation S ("Regulation

                              4.    The proposed transfer of Notes is not part

                                    remuneration in respect of the Notes, and
                                    the proposed transfer takes place during the

                              2.    Unless the circumstances described in
                                    paragraph 1(ii) above are applicable, either
                                    (a) at the time our buy order was
                                    originated, we were outside the United

                                    in, on or through the facilities of a
                                    designated offshore securities market and we
                                    did not pre-arrange the transaction in the
                                    United States.

or any other available exemption from the registration requirements of the

         Prior to the registration of any transfer in accordance with (c) or (d)
above, we acknowledge that a duly completed and signed certificate (the form of
