the giving of such notice or report. In any case where notice to Holders is to
be given, neither the failure to send such notice, nor any defect in any
notice, to any particular Holder shall affect the sufficiency of such notice
with respect to other Holders.

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

If by reason of the suspension of regular mail service or by
reason of any other cause it shall be impracticable to give such notice by
mail, such notification as shall be made with the approval of the Trustee shall
constitute a sufficient notification for every purpose hereunder.

the same force and effect as if made on the Interest Payment Date, Redemption
Date or Change of Control Payment Date or at the Stated Maturity, provided that
no interest shall accrue with respect to the payment of principal, premium, if

SECTION 1.14 PARI PASSU PAYMENTS TO SERIES B NOTES

(including Outstanding Additional Series B Notes); provided, however, that if
the Holders of the Series A Notes have declined to be redeemed to the fullest
extent permitted under Section 9.13 of this Indenture upon any Change of
Control, then principal on the Outstanding Series A Notes (including
Outstanding Additional Series A Notes) and on the Outstanding Series B Notes
(including Outstanding Additional Series B Notes) thereafter shall be paid pro
rata (rather than on a dollar-for-dollar basis) among the holders of such
Series A Notes or Series B Notes in the proportion that the aggregate amount of
principal due under such Series A Notes (including Outstanding Additional
Series A Notes) or Series B Notes (including Outstanding Additional Series B
Notes) held by the holder thereof bears to the combined aggregate amount of
principal due under both the Series A Notes (including Outstanding Additional
Series A Notes) and the Series B Notes (including Outstanding Additional Series
B Notes). Thereafter the Series B Notes which remain Outstanding shall be
retired in accordance with the Series B Indenture.

Any payment upon the Series B Notes in violation of this
Section or any other Section of this Indenture impresses a constructive trust
upon the recipients of such payment in an aggregate amount equal to the portion
of such aggregate payment required to have been paid upon the Outstanding
Series A Notes under this Section or such other applicable Section, which trust
may be enforced by the Trustee on behalf of the Outstanding Series A Notes.

plus the aggregate principal amount of Additional Series A Notes issued by the

upon which such Series A Notes are originally issued under this Indenture or
from the most recent Interest Payment Date to which interest has been paid or

A Notes shall be computed on the basis of twelve 30-day months and to be paid
on the actual number of days elapsed in a 360-day year. Interest shall be paid
in cash to the extent that (i) the Operating Company has funds legally
available to pay cash dividends on its preferred stock and payment of such cash
dividends is not prohibited under the Senior Indebtedness or the Bridge Loan
Agreement and (ii) the making of such cash interest payment would not directly
or indirectly (with the passage of time or giving of notice) cause a default or
event of default under the Senior Indebtedness or the Bridge Loan Agreement. To
the extent that the cash interest payment required to be made (after giving
effect to the preceding sentence) is not sufficient to pay the interest
payments due upon any Interest Payment Date under both the Series A Notes and
Series B Notes in full in cash, then the cash shall be allocated to the
interest payments pro rata among the holders of such Series A Notes or Series B
Notes in the proportion that the aggregate amount of interest due under such
Series A Notes or Series B Notes held by the holder thereof bears to the
combined aggregate amount of interest due under both Series A Notes and Series
B Notes. To the extent any interest payment on Series A Notes due upon any
Interest Payment Date is not paid in full in cash, the Company shall pay such
interest payment by the issuance of Additional Series A Notes having a
principal amount equal to the amount of interest not paid in cash on such
Interest Payment Date. Interest shall be payable semi-annually in arrears on
each April 30 and October 31, commencing April 30, 1997 and at Maturity.
Interest shall be payable on any overdue principal and on any overdue interest,
to the extent that the payment of such interest shall be legally enforceable,
at the rate of 14% per annum.

The principal of and premium, if any, and cash interest on the
Series A Notes shall be payable, and any Additional Series A Notes shall be
issued, at the office of the

CSK Group, Ltd. Series A Indenture
23
Company at the address set forth in the notice provision of this Indenture. To
the extent such payments are to be made in cash, such cash payment will be made
in such coin or currency of the United States of America as at the time of
payment is legal tender for the payment of public and private debts; provided,
however, that, at the option of the Company (and provided that comparable
payments on Series B Notes are to be paid in such manner), any payments made in
cash may be made by check mailed to the Person entitled thereto at his address
appearing on the Series A Note Register. Notwithstanding the foregoing, the
principal of and premium, if any, and interest, to the extent such interest is
to be paid in cash, on any Series A Note (other than the final payment of
principal on a Series A Note) at the option of the Holder thereof shall be paid
directly to such Holder, by wire transfer of immediately available funds,
without presentment, to the address designated by such Holder in writing.
Before selling or otherwise transferring any Series A Note, the Holder thereof
shall make a notation thereon of the aggregate amount of all payments of
principal theretofore made, and of the date to which interest has been paid;
the failure of the Holder to do so shall not, however, prejudice the right of
the Company to demonstrate the payment of such principal and interest. The
issuance of Additional Series A Notes in lieu of the payment of cash as
specified herein on any Interest Payment Date shall constitute full payment of
accrued and unpaid interest with respect to such Interest Payment Date.

The Series A Notes shall be issuable in registered form
without coupons in denominations of $1,000 or any integral multiple thereof,
or, in the case of Additional Series A Notes, $100 or any integral multiple
thereof (or any lesser amount to the extent necessary). Every Series A Note
shall be dated the date of its authentication, shall bear interest from the
applicable date and shall be payable on the dates specified on the face of the
form of Series A Note.

The rate of interest payable on any Series A Note shall in no
event exceed the maximum rate permissible under applicable law. If interest
would otherwise be payable to the Holder of a Series A Note in excess of the
maximum lawful amount, the interest payable shall be reduced to the maximum
amount permitted under applicable law; and if the Holder shall ever receive
anything of value deemed interest under applicable law in excess of the maximum
lawful amount, an amount equal to any excessive interest shall be applied to
the reduction of the principal of the Series A Note and not to payment of
interest, or if such excessive interest exceeds the unpaid balance of principal
on the Series A Note, such excess shall be refunded to the Company.

SECTION 2.04. EXECUTION, AUTHENTICATION AND DELIVERY.

The Series A Notes shall be executed on behalf of the Company
by its Chairman of the Board, its Vice Chairman, its President or a Vice
President, under its corporate seal reproduced thereon attested to by its
Secretary or an Assistant Secretary. The signature of any of these officers on
the Series A Notes may be manual or facsimile.

Series A Notes bearing the manual or facsimile signatures of
individuals who were at any time the proper officers of the Company shall bind
the Company, notwithstanding

CSK Group, Ltd. Series A Indenture
24
that such individuals or any of them have ceased to hold such offices prior to
the authentication and delivery of such Series A Notes or did not hold such
offices at the date of such Series A Notes.

At any time and from time to time after the execution and
delivery of this Indenture, the Company may deliver Series A Notes executed by
the Company to the Trustee for authentication, together with a Company Order
for the authentication and delivery of such Series A Notes; and the Trustee in
accordance with such Company Order shall authenticate and deliver such Series A
Notes as in this Indenture provided and not otherwise. In the case of a
Company Order relating to the issuance of Additional Series A Notes, such
Company Order shall also demonstrate the computation of the principal amount of
Additional Series A Notes issuable to each Holder.

No Series A Note shall be entitled to any benefit under this
Indenture or be valid or obligatory for any purpose unless there appears on
such Series A Note a certificate of authentication substantially in the form
provided for on Exhibit A, manually executed by the Trustee, and such
certificate upon any Series A Note shall be conclusive evidence, and the only
evidence, that such Series A Note has been duly authenticated and delivered
hereunder.

SECTION 2.05. TEMPORARY SERIES A NOTES.

Pending the preparation of definitive Series A Notes, the
Company may execute and upon Company Order the Trustee shall authenticate and
deliver temporary Series A Notes (which may be printed, lithographed,
typewritten or otherwise produced) in any authorized denomination and
substantially in the form of the definitive Series A Notes in lieu of which
they are issued, but with such appropriate omissions, insertions and variations
as the officers executing such Series A Notes may determine, as evidenced by
their execution of such Series A Notes. Every such temporary Series A Note
shall be executed by the Company and authenticated by the Trustee upon the same
conditions and in substantially the same manner, and with the same effect, as
the definitive Series A Notes. Without unreasonable delay the Company will
execute and deliver to the Trustee definitive Series A Notes and thereupon the
temporary Series A Notes may be surrendered in exchange for definitive Series A
Notes at the Principal Office of the Trustee without charge to the Holder.
Upon surrender for cancellation of any one or more temporary Series A Notes,
the Company shall execute and the Trustee shall authenticate and deliver in
exchange for the temporary Series A Notes an equal aggregate principal amount
of definitive Series A Notes. Until so exchanged, the temporary Series A Notes
in all respects shall be entitled to the same benefits under this Indenture as
definitive Series A Notes.

SECTION 2.06. REGISTRATION, REGISTRATION OF TRANSFER AND EXCHANGE.

All of the Series A Notes issued under this Indenture shall be
registered as to both principal and interest as specified in the Series A
Notes. The Company shall cause to be kept at the Principal Office of the
Trustee a register (the "Series A Note Register") in which, subject to such
reasonable regulations as the Trustee may prescribe, Series A Notes shall be
registered and the transfer of Series A Notes shall be

CSK Group, Ltd. Series A Indenture
25
registered as provided in this Article Two. The Series A Note Register shall
be in written form or in any other form capable of being converted into written
form within a reasonable time. The Trustee hereby is appointed "Series A Note
Registrar" for the purpose of registering Series A Notes and transfers of
Series A Notes as herein provided.

Upon due presentment for registration of transfer of any
Series A Note at any such office or agency maintained by the Company for such
purpose, the Company shall execute and the Trustee shall authenticate and
deliver in the name of the transferee or transferees a new Series A Note or
Series A Notes for an equal aggregate principal amount.

At the option of the Holder, Series A Notes may be exchanged
for a like aggregate principal amount of Series A Notes of other authorized
denominations. Series A Notes to be exchanged shall be surrendered at the
Principal Office of the Trustee and the Company shall execute and the Trustee
shall authenticate and deliver in exchange therefor the Series A Note or Series
A Notes which the Holder making the exchange shall be entitled to receive.

Every Series A Note presented for registration of transfer or
for exchange (if so required by the Company or the Trustee) shall be duly
endorsed by, or be accompanied by a written instrument of transfer in form
satisfactory to the Company and the Series A Note Registrar duly executed by,
the Holder or his attorney duly authorized in writing.

No service charge shall be made for any registration of
transfer or exchange of Series A Notes, but the Company may require payment of
a sum sufficient to cover any tax or other governmental charge that may be
imposed in connection therewith, other than an exchange pursuant to Section
2.05, 8.05, 9.13 or 10.08.

The Company shall not be required to (a) issue, register the
transfer of or exchange any Series A Note during a period beginning at the
opening of business 15 days before the day of the mailing of (i) a notice of
redemption of Series A Notes selected for redemption or (ii) a Change of
Control Offer pursuant to Section 9.13, and ending at the close of business on
the day of such mailing or (b) register the transfer of or exchange of any
Series A Note selected for redemption or to be repurchased pursuant to Section
9.13, in whole or in part, except the unredeemed or unrepurchased portion of
any Series A Note being redeemed or repurchased in part.

All Series A Notes issued upon any registration of transfer or
exchange of Series A Notes shall be valid obligations of the Company,
evidencing the same debt, and entitled to the same benefits under this
Indenture, as the Series A Notes surrendered upon such registration of transfer
or exchange.

CSK Group, Ltd. Series A Indenture

SECTION 2.07. MUTILATED, DESTROYED, LOST OR STOLEN SERIES A NOTES.

If any Series A Note shall become mutilated or be destroyed,
lost or stolen, the Company in its discretion may execute, and upon its request
the Trustee shall authenticate and deliver, a new Series A Note, bearing a
number not contemporaneously Outstanding, in exchange and substitution for the
mutilated Series A Note, or in lieu of and in substitution for the Series A
Note so destroyed, lost or stolen. In every case the applicant for a
substitute Series A Note shall furnish to the Company and to the Trustee such
security or indemnity as may be required by them to save each of them harmless
and, in every case of destruction, loss or theft, evidence to their
satisfaction of the destruction, loss or theft of such Series A Note and of the
ownership thereof.

Upon the issuance of any substitute Series A Note, the Company
may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expense connected therewith. If any Series A Note that has matured or is about
to mature or has been called for redemption shall become mutilated or be
destroyed, lost or stolen, the Company, instead of issuing a substitute Series
A Note, may pay or authorize the payment of the same (without surrender thereof
except in the case of a mutilated Series A Note) if the applicant for such
payment shall furnish to the Company and to the Trustee such security or
indemnity as may be required by them to save each of them harmless and, in case
of destruction, loss or theft, evidence satisfactory to them of the
destruction, loss or theft of such Series A Note and of the ownership thereof.

Every substitute Series A Note issued pursuant to the
provisions of this Section 2.07 by virtue of the fact that any Series A Note is
destroyed, lost or stolen shall constitute an additional contractual obligation
of the Company, whether or not the destroyed, lost or stolen Series A Note
shall be found at any time, and shall be entitled to all the benefits of this
Indenture equally and proportionately with all other Series A Notes duly issued
hereunder.

To the extent permitted by law, all Series A Notes shall be
held and owned upon the express condition that the foregoing provisions are
exclusive with respect to the replacement or payment of mutilated, destroyed,
lost or stolen Series A Notes and shall preclude any and all other rights or
remedies notwithstanding any law or statute existing or hereafter enacted to
the contrary with respect to the replacement or payment of negotiable
instruments or other securities without their surrender.

SECTION 2.08. PAYMENT OF INTEREST; INTEREST RIGHTS PRESERVED.

Interest on any Series A Note that is payable (including,
without limitation, by issuance of Additional Series A Notes), and is
punctually paid or duly provided for, on any Interest Payment Date shall be
paid to the Person in whose name that Series A Note is registered at the close
of business on the Regular Record Date for such interest.

CSK Group, Ltd. Series A Indenture
27
Any interest on any Series A Note that is payable (including,
without limitation, by issuance of Additional Series A Notes), but is not
punctually paid or otherwise duly provided for, on any Interest Payment Date
("Defaulted Interest") forthwith will cease to be payable to the Holder on the
relevant Regular Record Date by virtue of his having been such Holder; and such
Defaulted Interest may be paid by the Company, at its election in each case, as
provided in clause (a) or (b) below:

(a) The Company may elect to make payment (including,
without limitation, by issuance of Additional Series A Notes) any Defaulted
Interest to the Persons in whose names the Series A Notes are registered on the
Series A Note Register at the close of business on a Special Record Date for
the payment of such Defaulted Interest, which shall be fixed in the following
manner. The Company shall notify the Trustee in writing of the amount of
Defaulted Interest proposed to be paid on each Series A Note and of the
proposed payment date. At the same time the Company shall deposit with the
Trustee funds in an amount (or, to the extent so provided herein, Additional
Series A Notes in a principal amount) equal to the aggregate amount of
Defaulted Interest proposed to be paid, or shall make arrangements satisfactory
to the Trustee for such deposit prior to the date of the proposed payment, such
funds (or Additional Series A Notes) when deposited to be held in trust for the
benefit of the Persons entitled to such Defaulted Interest as provided in this
clause (a). Thereupon the Trustee shall fix a Special Record Date for the
payment of such Defaulted Interest which shall be not more than 15 days and not
less than ten days prior to the date of the proposed payment and not less than
ten days after the receipt by the Trustee of the notice of the proposed
payment. The Trustee promptly shall notify the Company of such Special Record
Date and, in the name and at the expense of the Company, shall cause notice of
the proposed payment of such Defaulted Interest and the Special Record Date
therefor to be mailed, first-class postage prepaid to each Holder at his
address as it appears on the Series A Note Register, not less than ten days
prior to such Special Record Date. Notice of the proposed payment of such
Defaulted Interest and the Special Record Date therefor having been so mailed,
such Defaulted Interest shall be paid to the Persons in whose names the Series
A Notes are registered at the close of business on such Special Record Date and
shall no longer be payable pursuant to the following clause (b).

(b) The Company may make payment of any Defaulted
Interest in any other lawful manner not inconsistent with the requirements of
any securities exchange on which the Series A Notes may be listed, and upon
such notice as may be required by such exchange if, after notice given by the
Company to the Trustee of the proposed payment pursuant to this clause (b),
such manner of payment shall be deemed practicable by the Trustee.

Subject to the foregoing provisions of this Section 2.08, each
Series A Note delivered under this Indenture upon registration of transfer or
in exchange for or in lieu of any other Series A Note shall carry the rights of
interest accrued and unpaid, and to accrue, that were carried by such other
Series A Note.

CSK Group, Ltd. Series A Indenture

SECTION 2.09. PERSONS DEEMED OWNERS.

Prior to due presentment of a Series A Note for registration
of transfer, the Company, the Trustee and any agent of the Company or the
Trustee may treat the Person in whose name such Series A Note is registered as
the owner of such Series A Note for the purpose of receiving payment of
principal of and premium, if any, and (subject to Section 2.08) interest on
such Series A Note and for all other purposes whatsoever, whether or not the
interest, premium, if any, or principal of such Series A Note shall be or have
become due, and none of the Company, the Trustee or any agent of the Company or
the Trustee shall be affected by notice to the contrary.

SECTION 2.10. CANCELLATION.

All Series A Notes surrendered for payment, redemption,
exchange or registration of transfer, if surrendered to any Person other than
the Trustee, shall be surrendered to the Trustee and promptly canceled by it.
The Company at any time may deliver to the Trustee for cancellation any Series
A Note previously authenticated and delivered hereunder that the Company may
have acquired in any manner whatsoever, and all Series A Notes so delivered
promptly shall be canceled by the Trustee. No Series A Note shall be issued in
lieu of or in exchange for any Series A Note canceled as provided in this
Section 2.10, except as expressly permitted by this Indenture. All canceled
Series A Notes held by the Trustee shall be disposed of as directed by a
Company Order. If the Company shall acquire any of the Series A Notes, such
acquisition shall not operate as a redemption or satisfaction of the
indebtedness represented by such Series A Notes unless and until the same are
delivered to the Trustee for cancellation.

at the expense of the Company, shall execute such instruments as the Company
reasonably may request acknowledging satisfaction and discharge of this
Indenture, when:

(A) have become due and payable,

Stated Maturity within one year, or

(C) are to be called for redemption
within one year under arrangements satisfactory to the Trustee for the giving

Company,

and the Company, in the case of (A), (B) or (C) above, has deposited or caused
to be deposited in accordance with this Indenture with the Trustee as trust
funds an amount sufficient to pay and discharge the entire indebtedness on such
Series A Notes not theretofore delivered to the Trustee for cancellation, for
principal, premium, if any, and interest to the date of such deposit (in the
case of Series A Notes that have become due and payable) or to the Stated
Maturity or Redemption Date, as the case may be;

(b) the Company has paid or caused to be paid all other

the obligations of the Trustee to any Authenticating Agent under Section 5.12
and, if funds shall have been deposited with the Trustee pursuant to Section
3.01(a), the obligations of the Trustee under Section 3.02 and the last
paragraph of Section 9.03 shall survive.

SECTION 3.02. APPLICATION OF TRUST FUNDS.

Subject to the provisions of Section 9.03, all funds deposited
with the Trustee pursuant to Section 3.01 shall be held in trust and applied by
it, in accordance with the provisions of the Series A Notes and this Indenture,
to the payment, either directly or through any paying agent (including the
Company if acting as its own paying agent) as the Trustee may determine, to the
Persons entitled thereto, of the principal, premium, if any, and interest for
whose payment such funds have been deposited with the Trustee.

SECTION 4.02. ACCELERATION OF MATURITY; RESCISSION AND ANNULMENT.

If an Event of Default occurs under clause (g), (h) or (j) of
Section 4.01, then the principal of and premium, if any, and the accrued
interest on all the Series A Notes shall become due and payable in cash
immediately. If any other Event of Default occurs and is continuing, then, and
in every such case, the Holders of not less than 40% in aggregate principal
amount of the Series A Notes then Outstanding, by notice in writing to the
Company and to the Trustee, may declare the principal amount of all the Series
A Notes to be due and payable in cash, and upon any such declaration such
principal amount shall become due and payable upon receipt by the Company and
the Trustee of such written notice given hereunder.

At any time after such a declaration of acceleration has been
made and before a judgment or decree for the payment of the amount due has been
obtained by the Trustee as hereinafter provided in this Article Four, the
Holders of a majority in aggregate principal amount of the Outstanding Series A
Notes, by written notice to the Company and the Trustee, may rescind and annul
such declaration and its consequences if:

(a) the Company has paid or deposited with the Trustee a
sum (or Additional Series A Notes to the extent any such amount was originally
payable by the issuance of Additional Series A Notes pursuant to Section 2.03)
sufficient to pay:

(i) the amount of all overdue installments of
interest on all Series A Notes in the case of an Event of Default specified in
Section 4.01(a),

(ii) the principal of and premium, if any, on all
Series A Notes that have become due to the extent such amounts have become due
otherwise than by such declaration of acceleration, and interest thereon (to
the extent that payment of such interest is lawful) at the applicable rate
provided in Section 2.03 in the case of an Event of Default specified in
Section 4.01(b),

(iii) to the extent that payment of such interest
is lawful, interest upon overdue interest at the applicable rate provided in
Section 2.03, and

(iv) all sums paid or advanced by the Trustee
hereunder and the reasonable compensation, expenses, disbursements and advances
of the Trustee, its agents and counsel; and

(b) all Events of Default, other than the nonpayment of
the principal of Series A Notes that have become due solely by such declaration
of acceleration, have been cured or waived as provided in Section 4.13.

No such rescission shall affect any subsequent default or
impair any right consequent thereon.

CSK Group, Ltd. Series A Indenture
33
SECTION 4.03. COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY THE
TRUSTEE.

The Company covenants that if:

(a) default is made in the payment of interest on any
Series A Note when such interest becomes due and payable and such default
continues for a period of 30 days, or

(b) default is made in the payment of the principal of or
premium, if any, on any Series A Note at the Maturity thereof,

the Company, upon demand of the Trustee, will pay to the Trustee in accordance
with this Indenture, for the benefit of the Holders of such Series A Notes, the
defaulted amount then due and payable on such Series A Notes for principal,
premium, if any, and interest, with interest (to the extent that payment of
interest on overdue interest is enforceable under applicable law) upon overdue
interest, at the applicable rate provided in Section 2.03, and, in addition
thereto, such further amount as shall be sufficient to cover the costs and
expenses of collection, including reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel.

If the Company fails to pay such amounts forthwith upon such
demand, the Trustee, in its own name and as trustee of an express trust, at the
request of the Holders of a majority in aggregate principal amount of the
Outstanding Series A Notes, will institute a judicial proceeding for the
collection of the sums so due and unpaid, will prosecute such proceeding to
judgment or final decree and will enforce against the Company or any other
obligor on the Series A Notes and collect the money adjudged or decreed to be
payable in the manner provided by law out of the property of the Company or any
other obligor on the Series A Notes, wherever situated.

If an Event of Default occurs and is continuing, the Trustee
at the request of the Holders of not less than 40% in aggregate principal
amount of the Outstanding Series A Notes will proceed to protect and enforce
its rights and the rights of the Holders by such judicial proceedings as such
Holders shall request to protect and enforce such rights, whether for the
specific enforcement of any covenant or agreement in this Indenture or in aid
of the exercise of any power granted herein, or to enforce any other proper
remedy.

SECTION 4.04. TRUSTEE MAY FILE PROOFS OF CLAIM.

In case of the pendency of any receivership, insolvency,
liquidation, bankruptcy, reorganization, arrangement, adjustment, composition
or other judicial proceeding relative to the Company or any other obligor on
the Series A Notes or the property of the Company or of such other obligor or
their creditors, the Trustee, irrespective of whether the principal of the
Series A Notes shall then be due and payable as therein expressed or by
declaration or otherwise and irrespective of whether the Trustee shall have
made any demand on the Company for the payment of overdue principal or
interest, at the

CSK Group, Ltd. Series A Indenture
34
request of a majority in aggregate principal amount of the Outstanding Series A
Notes, by intervention in such proceedings or otherwise:

(a) will file and prove a claim for the whole amount of
principal, premium, if any, and interest owing and unpaid in respect of the
Series A Notes and file such 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 of the Holders allowed in such judicial
proceedings; and

(b) will collect and receive any funds or other property
payable or deliverable on any such claims and distribute the same;

and any Custodian or similar official in any such judicial proceeding hereby is
authorized by each Holder to make such payments to the Trustee and, in the
event that such payments shall be made directly to the Holders, to pay to the
Trustee any amount due it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any
other amounts due the Trustee under Section 5.07.

Nothing herein contained shall be deemed to authorize 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 Series A Notes or the rights of any Holder or to authorize the Trustee to
vote in respect of the claim of any Holder in any such proceeding.

SECTION 4.05. TRUSTEE MAY ENFORCE CLAIMS WITHOUT POSSESSION OF SERIES A NOTES.

All rights of action and claims under this Indenture or the
Series A Notes may be prosecuted and enforced by the Trustee without the
possession of any of the Series A Notes or the production thereof in any
proceeding relating thereto, and any such proceeding instituted by the Trustee
shall be brought in its own name as trustee of an express trust, and any
recovery of judgment, after provision for the payment of the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, shall be for the ratable benefit of the Holders of the Series A
Notes in respect of which such judgment has been recovered.

SECTION 4.06. APPLICATION OF FUNDS COLLECTED.

Any funds and Additional Series A Notes collected by the
Trustee pursuant to this Article Four shall be applied in the following order,
at the date or dates fixed by the Trustee and, in case of the distribution of
such funds on account of principal, premium, if any, or interest, upon
presentation of the Series A Notes and the notation thereon of the payment if
only partially paid and upon surrender thereof if fully paid:

written notice thereof to the Trustee and to the Company. The Trustee at any
time may terminate the agency of an Authenticating Agent by giving written
notice thereof to such Authenticating Agent and the Company. Upon receiving
such a notice of resignation or upon such a termination, or in case at any time
such Authenticating Agent shall cease to be qualified and eligible in
accordance with the provisions of this Section 5.12, the Trustee may appoint a
successor Authenticating Agent which shall be acceptable to the Company and
shall mail written notice of such appointment by first-class mail, postage
prepaid, to all Holders as their names and addresses appear in the Series A
Note Register. Any successor Authenticating Agent upon acceptance of its
appointment hereunder shall become vested with all the rights, powers and
duties of its predecessor hereunder, with like effect as if originally named as
an Authenticating Agent herein.

time to time reasonable compensation for its services under this Section 5.12,

other offices or agencies (in or outside of the above location) where the

maintain an office or agency in Arizona, for the payment of the Series A Notes.
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 9.03. FUNDS FOR SERIES A NOTE PAYMENTS TO BE HELD IN TRUST.

If the Company at any time shall act as its own paying agent,
on or before each due date of the principal of or premium, if any, or interest

hold in trust for the benefit of the Persons entitled thereto a sum (or
Additional Series A Notes to the extent provided herein) sufficient to pay the
principal, premium, if any, or interest so becoming due until such sums shall
be paid (or such Additional Series A Notes issued) to such Persons or otherwise
disposed of as herein provided and promptly will notify the Trustee of its

default, upon the written request of the Trustee, forthwith pay to the Trustee
all sums and Additional Series A Notes so held in trust by such paying agent.

The Company, at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, may pay
in accordance with this

CSK Group, Ltd. Series A Indenture
51
Indenture, or by Company Order direct any paying agent to pay in accordance
with this Indenture, to the Trustee all funds and Additional Series A Notes
held in trust by the Company or such paying agent hereunder, such funds and
Additional Series A Notes to be held by the Trustee upon the same trusts as
those upon which such funds and Additional Series A Notes were held by the
Company or such paying agent; and upon such payment by the Company or any
paying agent to the Trustee, the Company or such paying agent shall be released
from all further liability with respect to such funds and Additional Series A
Notes.

Any funds or Additional Series A Notes deposited with the
Trustee or any paying agent, or then held by the Company, in trust for the
payment of the principal of or premium, if any, or interest on any Series A
Note and remaining unclaimed for two years after such principal, premium, if
any, or interest has become due and payable shall be paid to the Company on
Company Request or (if then held by the Company) shall be discharged from such
trust; and the Holder of such Series A Note thereafter, as an unsecured general
creditor, shall look only to the Company for payment thereof, and all liability
of the Trustee or such paying agent with respect to such funds and Additional
Series A Notes, and all liability of the Company as trustee thereof, shall
thereupon cease; provided, however, that the Trustee or such paying agent,
before being required to make any such payment or delivery, at the expense of
the Company may cause to be published once, in a newspaper published in the
English language, customarily published on each Business Day and of general
circulation in Phoenix, Arizona, notice that such funds and/or Additional

cause to be done, all things necessary to preserve and keep in full force and
effect its corporate existence, rights (charter and statutory) and franchises;
provided, however, that the Company shall not be required to preserve or cause
to be preserved any such right or franchise if, in the judgment of the Company
or the relevant Significant Subsidiary, it is determined that the preservation
thereof is no longer desirable in the conduct of the business of the Company or
the Significant Subsidiary, as the case may be, and that the loss thereof is
not disadvantageous in any material respect to the Holders.

SECTION 9.05. MAINTENANCE OF PROPERTIES.

The Company will cause all properties used or useful in the
conduct of its and any Significant Subsidiary's business to be maintained and
kept in good condition, repair and working order and supplied with all

the Company or any Significant Subsidiary from discontinuing the operation or

in the conduct of its business and not disadvantageous in any material respect
to the Holders.

SECTION 9.06. PAYMENT OF TAXES AND OTHER CLAIMS.

The Company will pay or discharge or cause to be paid or
discharged, and will cause each Significant Subsidiary to pay, discharge or

property of the Company or such Significant Subsidiary and (b) all lawful,
material claims for labor, materials and supplies that, if unpaid, might by law

such tax, assessment, charge or claim whose amount, applicability or validity
is being contested in good faith by appropriate proceedings.

SECTION 9.07. PROVISION OF REPORTS.

The Company shall furnish to the Trustee copies of semi-annual

practicable after its receipt thereof.

SECTION 9.08. WAIVER OF USURY DEFENSE.

To the extent permitted by applicable law, the Company agrees
that it will not assert, plead (as a defense or otherwise) or in any manner

plead or claim) in any action, suit or proceeding that the effective interest
rate on the Series A Notes (or any interest or other amounts payable pursuant
to Section 2.03 hereof or the Series A Notes) violates present or future usury
or other laws relating to the interest payable on any indebtedness and will not
otherwise avail itself (and will actively resist any attempt to compel it to
avail itself) of the benefits or advantages of any such laws.

SECTION 9.09. WAIVER OF CERTAIN COVENANTS.

The Company may omit in any particular instance to comply with
any covenant or condition set forth in this Article Nine, other than any such

of such Holders, either waive such compliance in such instance or generally
waive compliance with such covenant or condition, but no such waiver shall

CSK Group, Ltd. Series A Indenture
53
extend to or affect such covenant or condition except to the extent so
expressly waived and, until such waiver shall become effective, the obligations
of the Company and the duties of the Trustee in respect of any such covenant or
condition shall remain in full force and effect. If such covenant or condition
inures to the benefit of the Series B Note Holders, such waiver shall not be
effective absent the consent of Series B Holders having at least a majority in
principal amount of Outstanding Series B Notes.

ARTICLE ELEVEN
SUBORDINATION

SECTION 11.01. AGREEMENT OF SUBORDINATION.

The Company covenants and agrees, and each Holder of Series A
Notes by his acceptance thereof likewise covenants and agrees, that all Series
A Notes shall be issued subject to the provisions of this Article Eleven; and
each Person holding any Series A Note,

CSK Group, Ltd. Series A Indenture
60
whether upon original issue or exchange or upon transfer or assignment thereof,
accepts and agrees to be bound by such provisions.

The payment of the principal of and premium, if any, interest
and any other amount due on all Series A Notes, to the extent and in the manner
hereinafter set forth, shall be subordinated and subject in right of payment to
the prior payment in full in cash of all Senior Indebtedness (including
interest accruing after the filing of a petition by or against the Company
under any Bankruptcy Law, whether or not allowed as a claim), whether
outstanding at the date hereof or hereafter incurred.

SECTION 11.02. PAYMENTS TO HOLDERS OF SERIES A NOTES.

In the event and during the continuation of any default in the
payment of principal of, premium, if any, or interest on or any other payment
due under any Senior Indebtedness, then, unless and until such default shall
have been cured or waived, no payment or distribution shall be made by or on
behalf of the Company with respect to the principal of or premium, if any,
interest or any other payment due on or with respect to the Series A Notes or
the Series B Notes.

In the event and during the continuation of any default (other
than a default of any payment due) with respect to any Senior Indebtedness
permitting the Senior Lenders thereunder to accelerate the maturity thereof,
then, unless and until such default shall have been cured or waived, no payment
or distribution shall be made by or on behalf of the Company with respect to
the principal of or premium, if any, interest or any other payment due on or
with respect to the Series A Notes or the Series B Notes, if written notice of
such default shall have been given to the Trustee and the Company by the Bank
Agent, during the period commencing on the date on which such notice is
received by the Company and the Trustee and ending on the earlier to occur of
(a) the 179th day thereafter or (b) the day on which such default is cured or
waived; provided, however, that this sentence shall not prohibit any payment of
any installment of principal of or premium, if any, interest or any other
payment due on the Series A Notes for more than 179 days in any 365-day period
and provided, further, that no default that once formed the basis for any such
notice by the Bank Agent shall form the basis of any subsequent notice under
this paragraph. For purposes of the preceding sentence, "default" shall mean
any default or failure to observe or perform any provision of any instrument
with respect to the Senior Indebtedness which ipso facto causes the principal
and interest to be immediately due and payable, or after the giving of notice,
the expiration of any grace periods, or both, so that the Senior Lenders or
administrative agent are entitled to accelerate the maturity thereof.

Indebtedness first shall be paid in full in cash, or payment thereof provided
for in cash in accordance with its terms, before any payment is made on account
of the principal of or premium, if any, interest or any other amount due on or
with respect to the Series A Notes; and upon any such dissolution, winding-up,
liquidation, reorganization, assignment, marshaling or proceedings:

(a) the Senior Lenders shall be entitled to receive
payment in full in cash and cash equivalents of all Senior Indebtedness before
the Holders of the Series A Notes and the Trustee shall be entitled to receive
any payment of principal or premium, if any, or interest on or other amounts
payable with respect to the Series A Notes or the Series B Notes; and

(b) any payment by the Company, or distribution of assets
or securities of the Company of any kind or character, whether in cash,
property or securities, to which the Holders of the Series A Notes or the
Trustee would be entitled except for the provisions of this Article Eleven,
shall be paid by the Company or by any custodian, agent or other Person making
such payment or distribution, or by any Holder, the Trustee, any paying agent
or any depository if received by it, directly to the Senior Lenders or their
representative or representatives, or the trustee or trustees under any
indenture pursuant to which any instruments evidencing any such Senior
Indebtedness may have been issued, as their respective interests may appear, to
the extent necessary to pay all such Senior Indebtedness in full in cash or
cash equivalents, after giving effect to any concurrent payment or distribution
to or for the Senior Lenders.

In the event that, notwithstanding the foregoing, any payment
by or distribution of assets or securities of the Company of any kind or
character, whether in cash, property or securities, prohibited by the
foregoing, shall be received by the Trustee or the Holders before all such
Senior Indebtedness is paid in full in cash, such payment or distribution shall
be held in trust for the benefit of and shall be paid over or delivered to the
Senior Lenders or their representative or representatives, or to the trustee or
trustees under any indenture pursuant to which any instrument evidencing any
such Senior Indebtedness may have been issued, as their respective interests
may appear, for application to the payment of all such Senior Indebtedness
remaining unpaid to the extent necessary to pay all such Senior Indebtedness in
full in cash or cash equivalents in accordance with its terms, after giving
effect to any concurrent payment or distribution to or for the benefit of the

Company into another corporation, or the liquidation or dissolution of the
Company following the conveyance or transfer of its property or assets as an
entirety or substantially as an entirety to another corporation, upon the terms

CSK Group, Ltd. Series A Indenture
63
Notes shall be paid in full; and, for the purposes of such subrogation, no
payments or distributions to the Senior Lenders of any cash, property or
securities to which the Holders of the Series A Notes or the Trustee would be
entitled except for the provisions of this Article Eleven, and no payment over
pursuant to the provisions of this Article Eleven to or for the benefit of the

its creditors other than the Senior Lenders and the Holders, be deemed to be a
payment by the Company to or on account of such Senior Indebtedness. It is
understood that the provisions of this Article Eleven are and are intended
solely for the purpose of defining the relative rights of the Holders on the
one hand and the Senior Lenders on the other hand.

Nothing contained in this Article Eleven or elsewhere in this

creditors other than the Senior Lenders and the Holders, the obligation of the

principal of and premium, if any, and interest on the Series A Notes as and
when the same shall become due and payable in accordance with their terms, or
is intended to or shall affect the relative rights of the Holders and creditors
of the Company other than the Senior Lenders, nor shall anything herein (except
to the extent contemplated by Sections 1.14 and 4.02) or therein prevent the

otherwise permitted by applicable law upon default under this Indenture,
subject to the rights, if any, under this Article Eleven of the Senior Lenders
in respect of cash, property or securities of the Company received upon the
exercise of any such remedy.

Upon any payment or distribution of assets or securities of

provisions of Section 5.01, and the Holders shall be entitled to rely upon any
order or decree made by any court of competent jurisdiction in which such
dissolution, winding-up, liquidation, reorganization, assignment, marshaling or
proceedings are pending, or a certificate of any Custodian, agent or other
Person making such payment or distribution, delivered to the Trustee or to the
Holders, for the purpose of ascertaining the Persons entitled to participate in
such payment or distribution, the Senior Lenders and the holders of other
indebtedness of the Company, the amount thereof or payable thereon, the amount
or amounts paid or distributed thereon and all other facts pertinent thereto or
to this Article Eleven.

SECTION 11.05. AUTHORIZATION BY HOLDERS OF SERIES A NOTES.

for any and all such purposes including, without limitation in the event of any
dissolution, winding-up, liquidation, marshaling of assets and liabilities or
reorganization of the Company (whether in bankruptcy, insolvency, receivership,
reorganization or similar proceedings or upon an assignment for the benefit of
creditors or otherwise) tending towards liquidation of the business and assets
of the Company, the filing of

CSK Group, Ltd. Series A Indenture

interest on and other obligations with respect to the Series A Notes in the
form required in those proceedings.

SECTION 11.06. NOTICE TO TRUSTEE.

The Company shall give prompt written notice to the Trustee of
any fact known to the Company that would prohibit the making of any payment or
distribution to or by the Trustee in respect of the Series A Notes pursuant to
the provisions of this Article Eleven. Notwithstanding the provisions of this
Article Eleven or any other provision of this Indenture, the Trustee shall not
be charged with knowledge of the existence of any fact that would prohibit the
making of any payment or distribution to or by the Trustee in respect of the
Series A Notes pursuant to the provisions of this Article Eleven, unless and
until a Responsible Officer shall have received written notice thereof at the
Principal Office of the Trustee from the Company or a Senior Lender or from any
trustee for Senior Indebtedness or for purposes of Section 11.03 from the
trustee for the Series B Notes; and prior to the receipt of any such written
notice the Trustee, subject to the provisions of Section 5.01, shall be
entitled in all respects to assume that no such facts exist; provided, however,
that if the Trustee shall not have received the notice provided for in this
Section 11.06 within one Business Day prior to the date upon which by the terms
hereof any funds may become payable for any purpose (including without
limitation the payment of the principal of or premium, if any, or interest on
any Series A Note), then, anything herein contained to the contrary
notwithstanding, the Trustee shall have full power and authority to receive
such funds and to apply the same to the purpose for which they were received
and shall not be affected by any notice to the contrary that may be received by
it within one Business Day prior to such date.

The Trustee, subject to the provisions of Section 5.01, shall
be entitled to rely on the delivery to it of a written notice by a Person
representing himself to be a Senior Lender (or a trustee or agent on behalf of
a Senior Lender) or from the trustee for the Series B Notes for purposes of
Section 11.03 to establish that such notice has been given by a Senior Lender
or a trustee or agent on behalf of any such Senior Lender. In the event that
the Trustee determines in good faith that further evidence is required with
respect to the right of any Person as a Senior Lender or a holder of the Series
B Notes to participate in any payment or distribution pursuant to this Article
Eleven, the Trustee may request such Person to furnish evidence to the
reasonable satisfaction of the Trustee as to the amount of Senior Indebtedness
held by such Person, or the amount of Series B Notes held, the extent to which
such Person is entitled to participate in such payment or distribution and any
other fact pertinent to the rights of such Person under this Article Eleven,
and if such evidence is not furnished, the Trustee may defer any payment to
such Person pending judicial determination as to the right of such Person to
receive such payment or distribution.

SECTION 11.07. TRUSTEE'S RELATION TO SENIOR INDEBTEDNESS.

The Trustee in its individual capacity shall be entitled to
all the rights set forth in this Article Eleven in respect of any Senior
Indebtedness at any time held by it, to the same

CSK Group, Ltd. Series A Indenture
65
extent as any other Senior Lender, and no provision of this Indenture shall
deprive the Trustee of any of its rights as such Senior Lender.

With respect to the Senior Lenders, the Trustee undertakes to
perform or to observe only such covenants and obligations as are specifically
set forth in this Article Eleven, and no implied covenant or obligation with
respect to the Senior Lenders shall be read into this Indenture against the
Trustee. The Trustee shall not be deemed to owe any fiduciary duty to the
Senior Lenders.

Whenever a distribution is to be made or a notice given to
Senior Lenders, the distribution may be made and the notice given to their
representative(s).

SECTION 11.08. NO IMPAIRMENT OF SUBORDINATION.

No right of any present or future Senior Lender to enforce
subordination as herein provided at any time in any way shall be prejudiced or
impaired by any act or failure to act on the part of the Company or by any act
or failure to act, in good faith, by any such Senior Lender, or by any
noncompliance by the Company with the terms, provisions and covenants of this
Indenture, regardless of any knowledge thereof which any such Senior Lender may
have or otherwise be charged with.

SECTION 11.09. ARTICLE ELEVEN NOT TO PREVENT EVENTS OF DEFAULT.

The failure to make a payment on account of principal,
premium, if any, interest or any other amount due hereunder or on the Series A
Notes by reason of any provision in this Article Eleven shall not be construed
as preventing the occurrence of an Event of Default under Section 4.01 but the
remedies in respect thereof are limited as set forth in Article Four and any
amounts realized through the exercise of such remedies shall be subject to the
provisions of this Article Eleven.

SECTION 11.10. CONTINUING EFFECT.

The foregoing provisions constitute a continuing offer to all
Persons who become, or continue to be, Senior Lenders; and such provisions are
made for the benefit of the Senior Lenders, and such Senior Lenders are hereby
made obligees hereunder the same as if their names were written herein as such,
and they and/or each of them may proceed to enforce such provisions and need
not prove reliance thereon.

SECTION 11.11. INDIVIDUAL RIGHTS OF SENIOR LENDERS.

A Senior Lender in its individual or any other capacity may
become the owner or pledgee of Series A Notes and may otherwise deal with the
Company or any Subsidiary or Affiliate of the Company with the same rights as
if it were not a Senior Lender.

CSK Group, Ltd. Series A Indenture

SECTION 11.12. ARTICLE APPLICABLE TO PAYING AGENTS AND DEPOSITARIES.

In case at any time any paying agent or depository other than
the Trustee shall have been appointed by the Company and be then acting
hereunder, the term "Trustee" as used in this Article shall in such case
(unless the context otherwise requires) be construed as extending to and
including such paying agent or depository within its meaning as fully for all
intents and purposes as if such paying agent or depository were named in this
Article in addition to or in place of the Trustee; provided, however, that
Section 11.07 shall not apply to the Company if it acts as paying agent.

AS STATED IN THE INDENTURE REFERRED TO HEREIN, THE RIGHTS OF THE HOLDER HEREOF
ARE SUBJECT TO SUBORDINATION IN CERTAIN EVENTS TO ALL SENIOR INDEBTEDNESS (AS
DEFINED IN THE INDENTURE) OF THE COMPANY.

CSK Group, Ltd., a Delaware corporation (the "Company", which
term includes any successor corporation under the Indenture hereinafter
referred to), for value received, hereby promises to pay to
_____________________________ _________, or registered assigns, the principal
sum of US $_______________________ on October 31, 2008, and to pay interest
thereon at the rate of 12% per annum from the date this Series A Note was
originally issued under the Indenture or from the most recent Interest Payment
Date to which interest has been paid or duly provided for, as the case may be,
until Maturity. Interest shall be computed for any Interest Payment Date by
annualizing the interest rate and dividing by two, or for any period other than
a full interest period, on the basis of a 360-day year of twelve 30-day months
and to be paid according to the actual number of days elapsed. Interest at
such rate shall be payable in arrears on each April 30 and October 31,
commencing April 30, 1997 and at Maturity. Interest shall be payable at the
rate of 14% per annum on any overdue principal and on any overdue interest, to
the extent that the payment of such interest shall be legally enforceable. The
interest so payable, and punctually paid or duly provided for, on any Interest
Payment Date, will be paid in cash or by issuing Additional Series A Notes
having a principal amount equal to the amount of such interest so payable, as
provided in the Indenture, to the Person in whose name this Series A Note is
registered at the close of business on the Regular

69
Record Date for such interest, which shall be the April 15 and October 15, as
the case may be, next preceding such Interest Payment Date. Any such interest
not so punctually paid or duly provided for on any Interest Payment Date
forthwith will cease to be payable to the Holder on such Regular Record Date by
virtue of his having been such Holder and shall be paid to the Person in whose
name this Series A Note is registered at the close of business on a Special
Record Date for the payment of such Defaulted Interest to be fixed by the
Trustee, notice of which shall be given to Holders not less than ten days prior
to such Special Record Date, or be paid at any time in any other lawful manner
not inconsistent with the requirements of any securities exchange on which the
Series A Notes may be listed, and upon such notice as may be required by such
exchange, all as more fully provided in the Indenture. Payment of the
principal of and premium, if any, and interest on this Series A Note will be
made at the office of the Company at the address set forth in the notice
provision of the Indenture, in such coin or currency of the United States of
America as at the time of payment is legal tender for the payment of public and
private debts or by issuing Additional Series A Notes having a principal amount
equal to the amount of such interest so payable; provided, however, that at the
option of the Company payment may be made by check or Additional Series A Notes
having a principal amount equal to the amount of such interest so payable
mailed to the Person entitled thereto at his address appearing on the Series A
Note Register in accordance with this Indenture. Notwithstanding the
foregoing, at the option of the Holder hereof the principal of and premium, if
any, and interest on this Series A Note (other than the final payment of
principal) which is paid in cash shall be paid directly to such Holder, by wire
transfer of immediately available funds, without presentment, to the address
designated by such Holder in writing. Before selling or otherwise transferring
this Series A Note, such Holder will make a notation hereon of the aggregate
amount of all payments of principal theretofore made, and of the date to which
interest has been paid.

Reference is made to the further provisions of this Series A
Note set forth on the reverse hereof. Such further provisions shall for all
purposes have the same effect as though fully set forth on this front side of
this Series A Note.

THIS SERIES A NOTE SHALL BE DEEMED TO BE A CONTRACT MADE UNDER
THE LAWS OF THE STATE OF NEW YORK, AND FOR ALL PURPOSES SHALL BE CONSTRUED IN
ACCORDANCE WITH AND GOVERNED BY THE LAWS THEREOF.

This Series A Note shall not be valid or become obligatory for
any purpose until the certificate of authentication hereon shall have been
manually signed by the Trustee as provided in the Indenture.

(REVERSE OF SERIES A NOTE)

This Series A Note is one of a duly authorized issue of Series
A Notes of the Company, designated as its 12% Subordinated Series A Notes due
October 31, 2008 (the "Series A Notes"), limited in aggregate principal amount
to not more than $10,000,000, plus the aggregate principal amount of Additional
Series A Notes issued by the Company pursuant to the terms of an Indenture
dated as of October 30, 1996 (the "Indenture"), from the Company to
TransAtlantic Finance, Ltd. (the "Trustee", which term includes any successor
Trustee under the Indenture),and to be issued under such Indenture and to which
Indenture and all indentures supplemental thereto reference is hereby made for
a description of the rights, limitations of rights, obligations, duties and
immunities thereunder of the Trustee, the Company and the Holders of Series A
Notes and of the terms upon which the Series A Notes are, and are to be,
authenticated and delivered.

Subject to the terms of Article Ten and Eleven of the
Indenture, the Series A Notes are subject to redemption at any time or from
time to time, upon not less than 30 days' nor more than 60 days' notice, as a
whole or in part, at the election of the Company, at any time hereafter at One
Hundred and One Percent (101%) of the principal amount redeemed plus accrued
and unpaid interest thereon to the date of such redemption on the amount
redeemed.

Interest that is due and payable on or prior to any such
Redemption Date will be payable to the Holders of such Series A Notes of record
at the close of business on the relevant Record Date referred to on the face
hereof, all as provided in the Indenture.

In the event of redemption of this Series A Note in part only,
a new Series A Note or Series A Notes for the unredeemed portion hereof will be
issued in the name of the Holder hereof upon the cancellation hereof.

The Indenture further provides that, upon the occurrence of a
Change of Control, the Company shall notify the Trustee in writing and shall
promptly make an offer to purchase, on the last day of the next fiscal quarter
of the Company commencing after the Change of Control Date (the "Change of
Control Payment Date"), all Series A Notes then Outstanding at a purchase price
equal to the price specified in this Series A Note for optional redemption,
together with accrued interest to and including the Change of Control Payment
Date subject to certain rights of the holders of the Series B Notes to
participate in such redemption.

If an Event of Default, as defined in the Indenture, shall
have occurred and be continuing, the principal of all Series A Notes may be
declared, and upon such declaration

Exhibit A -- Form of Series A Note
72
shall become, due and payable, in the manner, with the effect and subject to
the conditions provided in the Indenture.

So long as any Senior Indebtedness is outstanding or the
Company shall have any outstanding obligation thereunder, the Company may not
amend or modify in certain respects any of the subordination provisions
contained in the Indenture as against any Senior Lender who has not consented
thereto.

The Indenture contains provisions permitting the Company and
the Trustee, with the consent of the Holders of not less than a majority in
aggregate principal amount of the Series A Notes at the time Outstanding, and
the Series B Holders of not less than a majority in aggregate principal amount
of the Series B Notes at the time Outstanding, in each case evidenced as in the
Indenture provided, to execute supplemental indentures adding any provision to
or changing in any manner or eliminating any provision of the Indenture or of
any supplemental indenture or modifying in any manner the rights of the Holders
of the Series A Notes; provided that no such supplemental indenture shall,
without the consent of the Holder of each Outstanding Series A Note affected
thereby, (a) change the Stated Maturity of the principal of, or Interest
Payment Date with respect to any payment of interest on, any Series A Note, or
reduce the rate or extend the time of payment of interest thereon, or reduce
the principal amount thereof or premium, if any, thereon, or impair the right
to institute suit for the payment on or after the Stated Maturity thereof or
Interest Payment Date therefor, as the case may be (or, in the case of
redemption or repurchase, on or after the Redemption Date or Change of Control
Payment Date), or change the place of payment where, or the coin or currency in
which, the principal, premium, if any, or interest is payable, (b) reduce the
aforesaid percentage in principal amount of the Outstanding Series A Notes the
consent of whose Holders is required to waive compliance with certain
provisions of the Indenture or certain defaults thereunder or to consent to any
such supplemental indenture or (c) modify certain sections of the Indenture or
the Events of Default thereunder. The Indenture also provides that, prior to
any declaration accelerating the maturity of the Series A Notes, the Holders of
not less than 40% of the aggregate principal amount of the Series A Notes at
the time Outstanding on behalf of the Holders of all of the Series A Notes may
waive any past default or Event of Default under the Indenture and its
consequences except a default in the payment of the principal of or premium, if
any, or interest on any of the Series A Notes and certain other defaults. Any
such consent or waiver by the Holder of this Series A Note (unless revoked as
provided in the Indenture) shall be conclusive and binding upon such Holder and
upon all future Holders of this Series A Note and any Series A Note that may be
issued in exchange or substitution herefor, irrespective of whether or not any
notation thereof is made upon this Series A Note or such other Series A Note.

No reference herein to the Indenture and no provision of this
Series A Note or of the Indenture (except to the extent contemplated by
Sections 1.14 and 4.02 of the Indenture) shall alter or impair the obligation
of the Company, which is absolute and

Exhibit A -- Form of Series A Note
73
unconditional, to pay the principal of and premium, if any, and interest on
this Series A Note at the place, at the times, at the rate and in the manner
herein prescribed.
