                        9 7/8% Senior Note due 2008, Series A

          1.  INTEREST. ELGAR HOLDINGS, INC., a Delaware corporation (the
"Company"), promises to pay interest on the principal amount of this Note at the
rate per annum shown above.  Interest on the Notes will accrue from the most
recent date on which interest has been paid or, if no interest has been paid,
from February 3, 1998.  The Company will pay interest semi-annually in arrears
on each Interest Payment Date, commencing August 1, 1998.  Interest will be
computed on the basis of a 360-day year of twelve 30-day months.

          The Company shall pay interest on overdue principal and on overdue
installments of interest from time to time on demand at the rate borne by the
Notes and on overdue installments of interest (without regard to any applicable
grace periods) to the extent lawful.

          2.  METHOD OF PAYMENT.  The Company shall pay interest on the Notes
(except defaulted interest) to the Persons who are the registered Holders at the
close of business on the Record Date immediately preceding the Interest Payment
Date even if the Notes are cancelled on registration of transfer or registration
of exchange (including pursuant to an Exchange Offer (as defined in the
Registration Rights Agreement)) after such Record Date.  Holders must surrender
Notes to a Paying Agent to collect principal payments.  The Company shall pay
principal and interest in money of the United States that at the time of payment
is legal tender for payment of public and private debts ("U.S. Legal Tender").
However, the Company may pay principal and interest by its check payable in such
U.S. Legal Tender or by wire transfer of immediately available funds.  The
Company may deliver any such interest payment to the Paying Agent or to a Holder
at the Holder's registered address.

          3.  PAYING AGENT AND REGISTRAR.  Initially, United States Trust
Company of New York (the "Trustee") will act as Paying Agent and Registrar.  The
Company may change any Paying Agent, Registrar or co-Registrar without notice to
the Holders.

          4.  INDENTURE.  The Company issued the Notes under an Indenture, dated
as of February 3, 1998 (as supplemented by the First Supplemental Indenture
thereto, dated as of February 3, 1998, the "Indenture"), among the Company, the
Subsidiary Guarantor and the Trustee.  This Note is one of a duly authorized
issue of Initial Notes of the Company designated as its 9 7/8%


                                         A-4


Senior Notes due 2008, Series A (the "Initial Notes").  The Notes are limited
(except as otherwise provided in the Indenture) in aggregate principal amount to
$150,000,000, which may be issued under the Indenture; PROVIDED the principal
amount of Initial Notes issued on the Issue Date is $90,000,000.  The Notes
include the Initial Notes, the Private Exchange Notes and the Exchange Notes
issued in exchange for the Initial Notes pursuant to the Registration Rights
Agreement.  The Initial Notes and the Exchange Notes are treated as a single
class of securities under the Indenture.  Capitalized terms herein are used as
defined in the Indenture unless otherwise defined herein.  The terms of the
Notes include those stated in the Indenture and those made part of the Indenture
by reference to the Trust Indenture Act of 1939 (15 U.S. Code Sections
77aaa-77bbbb) (the "TIA"), as in effect on the date of the Indenture.
Notwithstanding anything to the contrary herein, the Notes are subject to all
such terms, and Holders of Notes are referred to the Indenture and said Act for
a statement of them.  The Notes are general unsecured obligations of the
Company.

          Each Holder, by accepting a Note, agrees to be bound by all of the
terms and provisions of the Indenture, as the same may be amended from time to
time in accordance with its terms.

          5.  OPTIONAL REDEMPTION.  The Notes will be redeemable, at the
Company's option, in whole at any time or in part from time to time, on and
after February 1, 2003, upon not less than 30 nor more than 60 days' notice, at
the following redemption prices (expressed as percentages of the principal
amount thereof) if redeemed during the twelve-month period commencing on
February 1 of the years set forth below, plus, in each case, accrued and unpaid
interest thereon and Additional Interest, if any, to the date of redemption:




          Year                        Percentage
          ----                        ----------
                                   
          2003...................     104.938%
          2004...................     103.292%
          2005...................     101.646%
          2006 and thereafter....     100.000%




          OPTIONAL REDEMPTION UPON PUBLIC EQUITY OFFERINGS.  At any time, or 
from time to time, on or prior to February 1, 2001, the Company may, at its 
option, use the net cash proceeds of one or more Public Equity Offerings to 
redeem up to 35% of the sum of (i) the initial aggregate principal amount of 
Notes issued in the Offering and (ii) the respective initial aggre-


                                         A-5


gate principal amounts of Notes issued under the Indenture after the Issue 
Date at a redemption price equal to 109.875% of the principal amount thereof 
plus accrued and unpaid interest thereon and Additional Interest, if any, to 
the date of redemption; PROVIDED that at least 65% of the sum of (i) the 
initial aggregate principal amount of Notes issued in the Offering and (ii) 
the respective initial aggregate principal amounts of Notes issued under the 
Indenture after the Issue Date, remains outstanding immediately after any 
such redemption.  In order to effect the foregoing redemption with the 
proceeds of any Public Equity Offering, the Company shall make such 
redemption not more than 120 days after the consummation of any such Public 
Equity Offering.

          OPTIONAL REDEMPTION UPON CHANGE OF CONTROL.  Upon the occurrence of a
Change of Control prior to February 1, 2003, the Notes will be redeemable, in
whole or in part, at the option of the Company, upon not less than 30 nor more
than 60 days prior notice to each holder of Notes to be redeemed, at a
redemption price equal to the sum of (i) the then outstanding principal amount
thereof plus (ii) accrued and unpaid interest thereon and Additional Interest,
if any, to the redemption date plus (iii) the Applicable Premium.

          6.  NOTICE OF REDEMPTION.  Notice of redemption will be mailed at
least 30 days but not more than 60 days before the Redemption Date to each
Holder of Notes to be redeemed at such Holder's registered address.  Notes in
denominations larger than $1,000 may be redeemed in part.

          Except as set forth in the Indenture, if monies for the redemption of
the Notes called for redemption shall have been deposited with the Paying Agent
for redemption on such Redemption Date, then, unless the Company defaults in the
payment of such redemption price plus accrued interest, if any, the Notes called
for redemption will cease to bear interest from and after such Redemption Date
and the only right of the Holders of such Notes will be to receive payment of
the redemption price plus accrued interest, if any.

          7.  OFFERS TO PURCHASE.  Sections 4.14 and 4.15 of the Indenture
provide that, after certain Asset Sales and upon the occurrence of a Change of
Control, and subject to further limitations contained therein, the Company will
make an offer to purchase certain amounts of the Notes in accordance with the
procedures set forth in the Indenture.


                                         A-6


          8.  REGISTRATION RIGHTS.  Pursuant to a Registration Rights Agreement
between the Company and the Initial Purchaser, the Company will be obligated to
consummate an exchange offer pursuant to which the Holder of this Note shall
have the right to exchange this Note for Exchange Notes, which have been
registered under the Securities Act, in like principal amount and having terms
identical in all material respects as the Initial Notes.  The Holders of the
Initial Notes shall be entitled to receive certain additional interest payments
in the event such exchange offer is not consummated and upon certain other
conditions, all pursuant to and in accordance with the terms of the Registration
Rights Agreement.

          9.   DENOMINATIONS; TRANSFER; EXCHANGE.  The Notes are in registered
form, without coupons, and in denominations of $1,000 and integral multiples of
$1,000.  A Holder shall register the transfer of or exchange Notes in accordance
with the Indenture.  The Registrar may require a Holder, among other things, to
furnish appropriate endorsements and transfer documents and to pay certain
transfer taxes or similar governmental charges payable in connection therewith
as permitted by the Indenture.  The Registrar need not register the transfer of
or exchange of any Notes or portions thereof selected for redemption.

          10.  PERSONS DEEMED OWNERS.  The registered Holder of a Note shall be
treated as the owner of it for all purposes.

          11.  UNCLAIMED MONEY.  If money for the payment of principal or
interest remains unclaimed for one year, the Trustee and the Paying Agent will
pay the money back to the Company.  After that, all liability of the Trustee and
such Paying Agent with respect to such money shall cease.

          12.  DISCHARGE PRIOR TO REDEMPTION OR MATURITY.  If the Company at any
time deposits with the Trustee U.S. Legal Tender sufficient to pay the principal
of and interest on the Notes to redemption or maturity and complies with the
other provisions of the Indenture relating thereto, the Company and each
Subsidiary Guarantor will be discharged from certain provisions of the Indenture
and the Notes (including certain covenants, and including, under certain
circumstances, their obligation to pay the principal of and interest on the
Notes but without affecting the rights of the Holders to receive such amounts
from such deposits).

          13.  AMENDMENT; SUPPLEMENT; WAIVER.  Subject to certain exceptions set
forth in the Indenture, the Indenture or


                                         A-7


the Notes may be amended or supplemented with the written consent of the Holders
of a majority in aggregate principal amount of the Notes then outstanding, and
any past Default or Event of Default or noncompliance with any provision may be
waived with the written consent of the Holders of a majority in aggregate
principal amount of the Notes then outstanding.  Without notice to or consent of
any Holder, the parties thereto may amend or supplement the Indenture or the
Notes to, among other things, cure any ambiguity, defect or inconsistency,
provide for uncertificated Notes in addition to or in place of certificated
Notes, comply with any requirements of the Commission in order to effect or
maintain the qualification of the Indenture under the TIA or comply with Article
Five of the Indenture or make any other change that does not adversely affect
the rights of any Holder of a Note.

               14.  RESTRICTIVE COVENANTS.  The Indenture imposes certain
limitations on the ability of the Company and its Restricted Subsidiaries to,
among other things, incur additional Indebtedness, pay dividends or make certain
other Restricted Payments, consummate certain Asset Sales, enter into certain
transactions with Affiliates, incur liens, impose restrictions on the ability of
a Subsidiary to pay dividends or make certain payments to the Company and its
Subsidiaries, merge or consolidate with any other Person or sell, assign,
transfer, lease, convey or otherwise dispose of all or substantially all of the
assets of the Company.  Such limitations are subject to a number of important
qualifications and exceptions.  Pursuant to Section 4.06 of the Indenture, the
Company must annually report to the Trustee on compliance with such limitations.

          15.  SUCCESSORS.  When a successor assumes, in accordance with the
Indenture, all the obligations of its predecessor under the Notes and the
Indenture, the predecessor, subject to certain exceptions, will be released from
those obligations.

          16.  DEFAULTS AND REMEDIES.  If an Event of Default occurs and is
continuing, the Trustee or the Holders of not less than 25% in aggregate
principal amount of Notes then outstanding may declare all the Notes to be due
and payable in the manner, at the time and with the effect provided in the
Indenture.  Holders of Notes may not enforce the Indenture or the Notes except
as provided in the Indenture.  The Trustee is not obligated to enforce the
Indenture or the Notes unless it has received indemnity reasonably satisfactory
to it.  The Indenture permits, subject to certain limitations therein provided,
Holders of a majority in aggregate principal amount of the Notes then
outstanding to direct the Trustee in its exercise of


                                         A-8


any trust or power.  The Trustee may withhold from Holders of Notes notice of
any continuing Default or Event of Default (except a Default in payment of
principal or interest when due, for any reason or a Default in compliance with
Article Five of the Indenture) if it determines that withholding notice is in
their interest.

          17.  TRUSTEE DEALINGS WITH THE COMPANY AND ITS SUBSIDIARIES.  The
Trustee under the Indenture, in its individual or any other capacity, may become
the owner or pledgee of Notes and may otherwise deal with the Company, its
Subsidiaries or their respective Affiliates as if it were not the Trustee.

          18.  NO RECOURSE AGAINST OTHERS.  No director, officer, employee,
shareholder or incorporator as such, of the Company or any Subsidiary Guarantor,
as such, shall have any liability for any obligation of the Company under the
Notes, the Indenture or the Registration Rights Agreement or for any claim based
on, in respect of, or by reason of, such obligations or their creation.  Each
Holder of Notes by accepting a Note waives and releases all such liability.  The
waiver and release are part of the consideration for the issuance of the Notes.

          19.  AUTHENTICATION.  This Note shall not be valid until the Trustee
or Authenticating Agent manually signs the certificate of authentication on this
Note.

          20.  GOVERNING LAW.  This Note and the Indenture shall be governed by
and construed in accordance with the laws of the State of New York, as applied
to contracts made and performed within the State of New York, without regard to
principles of conflict of laws.  Each of the parties hereto agrees to submit to
the jurisdiction of the courts of the State of New York in any action or
proceeding arising out of or relating to this Note.

          21.  ABBREVIATIONS AND DEFINED TERMS.  Customary abbreviations may be

          22.  CUSIP NUMBERS.  Pursuant to a recommendation promulgated by the

                        9 7/8% Senior Note due 2008, Series B

          1.   INTEREST.  ELGAR HOLDINGS, INC., a Delaware corporation (the
"Company"), promises to pay interest on the principal amount of this Note at the
rate per annum shown above.  Interest on the Notes will accrue from the most
recent date on which interest has been paid or, if no interest has been paid,
from February 3, 1998.  The Company will pay interest semi-annually in arrears
on each Interest Payment Date, commencing August 1, 1998.  Interest will be
computed on the basis of a 360-day year of twelve 30-day months.

          The Company shall pay interest on overdue principal and on overdue
installments of interest from time to time on demand at the rate borne by the
Notes and on overdue installments of interest (without regard to any applicable
grace periods) to the extent lawful.

          2.   METHOD OF PAYMENT.  The Company shall pay interest on the Notes
(except defaulted interest) to the Persons who are the registered Holders at the
close of business on the Record Date immediately preceding the Interest Payment
Date even if the Notes are canceled on registration of transfer or registration
of exchange after such Record Date.  Holders must surrender Notes to a Paying
Agent to collect principal payments.  The Company shall pay principal and
interest in money of the United States that at the time of payment is legal
tender for payment of public and private debts ("U.S. Legal Tender").  However,
the Company may pay principal and interest by its check payable in such U.S.
Legal Tender or by wire transfer of immediately available funds.  The Company
may deliver any such interest payment to the Paying Agent or to a Holder at the
Holder's registered address.

          3.   PAYING AGENT AND REGISTRAR.  Initially, United States Trust
Company of New York (the "Trustee") will act as Paying Agent and Registrar.  The
Company may change any Paying Agent, Registrar or co-Registrar without notice to
the Holders.

          4.   INDENTURE.  The Company issued the Notes under an Indenture,
dated as of February 3, 1998 (as supplemented by the First Supplemental
Indenture dated as of February 3, 1998, the "Indenture"), among the Company, the
Subsidiary Guarantor and the Trustee.  This Note is one of a duly authorized
issue of Exchange Notes of the Company designated as its 9 7/8% Senior Notes due
2008, Series B (the "Exchange Notes").  The Notes


                                         B-4


include the 9 7/8% Notes due 2008, Series A (the "Initial Notes") and the
Exchange Notes, issued in exchange for the Initial Notes pursuant to a
Registration Rights Agreement.  The Notes are limited (except as otherwise
provided in the Indenture) in aggregate principal amount to $150,000,000, which
may be issued under the Indenture; PROVIDED the principal amount of Initial
Notes issued on the Issue Date was $90,000,000.  The Initial Notes and the
Exchange Notes are treated as a single class of securities under the Indenture.
Capitalized terms herein are used as defined in the Indenture unless otherwise
defined herein.  The terms of the Notes include those stated in the Indenture
and those made part of the Indenture by reference to the Trust Indenture Act of
1939 (15 U.S. Code Sections 77aaa-77bbbb) (the "TIA"), as in effect on the date
of the Indenture.  Notwithstanding anything to the contrary herein, the Notes
are subject to all such terms, and Holders of Notes are referred to the
Indenture and said Act for a statement of them.  The Notes are general unsecured
obligations of the Company.

          Each Holder, by accepting a Note, agrees to be bound by all of the
terms and provisions of the Indenture, as the same may be amended from time to
time in accordance with its terms.

          5.   OPTIONAL REDEMPTION.  The Notes will be redeemable, at the
Company's option, in whole at any time or in part from time to time, on and
after February 1, 2003, upon not less than 30 nor more than 60 days' notice, at
the following redemption prices (expressed as percentages of the principal
amount thereof) if redeemed during the twelve-month period commencing on
February 1 of the years set forth below, plus, in each case, accrued and unpaid
interest thereon and Additional Interest, if any, to the date of redemption:




          Year                     Percentage
          -----                    ----------
                                
          2003.................    104.938%
          2004.................    103.292%
          2005.................    101.646%
          2006 and thereafter..    100.000%



          OPTIONAL REDEMPTION UPON PUBLIC EQUITY OFFERINGS.  At any time, or
from time to time, on or prior to February 1, 2001, the Company may, at its
option, use the net cash proceeds of one or more Public Equity Offerings to
redeem up to 35% of the sum of (i) the initial aggregate principal amount of
Notes issued in the Offering and (ii) the respective initial aggregate principal
amounts of Notes issued under the Indenture af-


                                         B-5


ter the Issue Date at a redemption price equal to 109.875% of the principal
amount thereof plus accrued and unpaid interest thereon and Additional Interest,
if any, to the date of redemption; PROVIDED that at least 65% of the sum of
(i) the initial aggregate principal amount of Notes issued in the Offering and
(ii) the respective initial aggregate principal amounts of Notes issued under
the Indenture after the Issue Date, remains outstanding immediately after any
such redemption.  In order to effect the foregoing redemption with the proceeds
of any Public Equity Offering, the Company shall make such redemption not more
than 120 days after the consummation of any such Public Equity Offering.

          OPTIONAL REDEMPTION UPON CHANGE OF CONTROL.  Upon the occurrence of a
Change of Control prior to February 1, 2003, the Notes will be redeemable, in
whole or in part, at the option of the Company, upon not less than 30 nor more
than 60 days prior notice to each holder of Notes to be redeemed, at a
redemption price equal to the sum of (i) the then outstanding principal amount
thereof plus (ii) accrued and unpaid interest thereon and Additional Interest,
if any, to the redemption date plus (iii) the Applicable Premium.

          6.   NOTICE OF REDEMPTION.  Notice of redemption will be mailed at
least 30 days but not more than 60 days before the Redemption Date to each
Holder of Notes to be redeemed at such Holder's registered address.  Notes in
denominations larger than $1,000 may be redeemed in part.

          Except as set forth in the Indenture, if monies for the redemption of
the Notes called for redemption shall have been deposited with the Paying Agent
for redemption on such Redemption Date, then, unless the Company defaults in the
payment of such redemption price plus accrued interest, if any, the Notes called
for redemption will cease to bear interest from and after such Redemption Date
and the only right of the Holders of such Notes will be to receive payment of
the redemption price plus accrued interest, if any.

          7.   OFFERS TO PURCHASE.  Sections 4.14 and 4.15 of the Indenture
provide that, after certain Asset Sales and upon the occurrence of a Change of
Control, and subject to further limitations contained therein, the Company will
make an offer to purchase certain amounts of the Notes in accordance with the
procedures set forth in the Indenture.

          8.   DENOMINATIONS; TRANSFER; EXCHANGE.  The Notes are in registered
form, without coupons, and in denominations


                                         B-6


of $1,000 and integral multiples of $1,000.  A Holder shall register the
transfer of or exchange Notes in accordance with the Indenture.  The Registrar
may require a Holder, among other things, to furnish appropriate endorsements
and transfer documents and to pay certain transfer taxes or similar governmental
charges payable in connection therewith as permitted by the Indenture.  The
Registrar need not register the transfer of or exchange of any Notes or portions
thereof selected for redemption.

          9.   PERSONS DEEMED OWNERS.  The registered Holder of a Note shall be
treated as the owner of it for all purposes.

          10.  UNCLAIMED MONEY.  If money for the payment of principal or
interest remains unclaimed for one year, the Trustee and the Paying Agent will
pay the money back to the Company.  After that, all liability of the Trustee and
such Paying Agent with respect to such money shall cease.

          11.  DISCHARGE PRIOR TO REDEMPTION OR MATURITY.  If the Company at any
time deposits with the Trustee U.S. Legal Tender sufficient to pay the principal
of and interest on the Notes to redemption and complies with the other
provisions of the Indenture relating thereto, the Company and each Subsidiary
Guarantor will be discharged from certain provisions of the Indenture and the
Notes (including certain covenants, and including, under certain circumstances,
their obligation to pay the principal of and interest on the Notes but without
affecting the rights of the Holders to receive such amounts from such deposit).

          12.  AMENDMENT; SUPPLEMENT; WAIVER.  Subject to certain exceptions set
forth in the Indenture, the Indenture or the Notes may be amended or
supplemented with the written consent of the Holders of a majority in aggregate
principal amount of the Notes then outstanding, and any past Default or Event of
Default or noncompliance with any provision may be waived with the written
consent of the Holders of a majority in aggregate principal amount of the Notes
then outstanding.  Without notice to or consent of any Holder, the parties
thereto may amend or supplement the Indenture or the Notes to, among other
things, cure any ambiguity, defect or inconsistency, provide for uncertificated
Notes in addition to or in place of certificated Notes, comply with any
requirements of the Commission in order to effect or maintain the qualification
of the Indenture under the TIA or comply with Article Five of the Indenture or
make any other change that does not adversely affect the rights of any Holder of
a Note.


                                         B-7


          13.  RESTRICTIVE COVENANTS.  The Indenture imposes certain limitations
on the ability of the Company and its Restricted Subsidiaries to, among other
things, incur additional Indebtedness, pay dividends or make certain other
Restricted Payments, consummate certain Asset Sales, enter into certain
transactions with Affiliates, incur liens, impose restrictions on the ability of
a Subsidiary to pay dividends or make certain payments to the Company and its
Subsidiaries, merge or consolidate with any other Person or sell, assign,
transfer, lease, convey or otherwise dispose of all or substantially all of the
assets of the Company.  Such limitations are subject to a number of important
qualifications and exceptions.  Pursuant to Section 4.06 of the Indenture, the
Company must annually report to the Trustee on compliance with such limitations.

          14.  SUCCESSORS.  When a successor assumes, in accordance with the
Indenture, all the obligations of its predecessor under the Notes and the
Indenture, the predecessor, subject to certain exceptions, will be released from
those obligations.

          15.  DEFAULTS AND REMEDIES.  If an Event of Default occurs and is
continuing, the Trustee or the Holders of not less than 25% in aggregate
principal amount of Notes then outstanding may declare all the Notes to be due
and payable in the manner, at the time and with the effect provided in the
Indenture.  Holders of Notes may not enforce the Indenture or the Notes except
as provided in the Indenture.  The Trustee is not obligated to enforce the
Indenture or the Notes unless it has received indemnity reasonably satisfactory
to it.  The Indenture permits, subject to certain limitations therein provided,
Holders of a majority in aggregate principal amount of the Notes then
outstanding to direct the Trustee in its exercise of any trust or power.  The
Trustee may withhold from Holders of Notes notice of any continuing Default or
Event of Default (except a Default in payment of principal or interest when due,
for any reason or a Default in compliance with Article Five of the Indenture) if
it determines that withholding notice is in their interest.

          16.  TRUSTEE DEALINGS WITH THE COMPANY AND ITS SUBSIDIARIES.  The
Trustee under the Indenture, in its individual or any other capacity, may become
the owner or pledgee of Notes and may otherwise deal with the Company, its
Subsidiaries or their respective Affiliates as if it were not the Trustee.

          17.  NO RECOURSE AGAINST OTHERS.  No director, officer, employee,
shareholder or incorporator as such, of the Company or any Subsidiary Guarantor,
as such, shall have any li-


                                         B-8


ability for any obligation of the Company under the Notes, the Indenture or the
Registration Rights Agreement or for any claim based on, in respect of, or by
reason of, such obligations or their creation.  Each Holder of Notes by
accepting a Note waives and releases all such liability.  The waiver and release
are part of the consideration for the issuance of the Notes.

          18.  AUTHENTICATION.  This Note shall not be valid until the Trustee
or Authenticating Agent manually signs the certificate of authentication on this
Note.

          19.  GOVERNING LAW.  This Note and the Indenture shall be governed by
and construed in accordance with the laws of the State of New York, as applied
to contracts made and performed within the State of New York, without regard to
principles of conflict of laws.  Each of the parties hereto agrees to submit to
the jurisdiction of the courts of the State of New York in any action or
proceeding arising out of or relating to this Note.

Ladies and Gentlemen:

          In connection with our proposed purchase of 9 7/8% Senior Notes due
2008 (the "Notes") of EHI Holdings, Inc., a Delaware corporation (the
"Company"), we confirm that:

     1.   We have received a copy of the Offering Memorandum (the "Offering
Memorandum"), dated January 30, 1998, relating to the Notes and such other
information as we deem necessary in order to make our investment decision.  We
acknowledge that we have read and agreed to the matters stated in the section
entitled "Transfer Restrictions" of such Offering Memorandum.

     2.   We understand that any subsequent transfer of the Notes is subject to
certain restrictions and conditions set forth in the Indenture relating to the
Notes (the "Indenture") as described in the Offering Memorandum and the
undersigned agrees to be bound by, and not to resell, pledge or otherwise
transfer the Notes except in compliance with, such restrictions and conditions
and the Securities Act of 1933, as amended (the "Securities Act"), and all
applicable State securities laws.

     3.   We understand that the offer and sale of the Notes have not been
registered under the Securities Act, and that the Notes may not be offered or
sold within the United States or to, or for the account or benefit of, U.S.
persons except as permitted in the following sentence.  We agree, on our own
behalf and on behalf of any accounts for which we are acting as hereinafter
stated, that if we should sell any Notes, we will do so only (i) to the Company
or any subsidiary thereof, (ii) inside the United States in accordance with Rule
144A under the Securities Act to a "qualified institutional buyer" (as defined


                                         C-1


in Rule 144A promulgated under the Securities Act), (iii) inside the United
States to an institutional "accredited investor" (as defined below) that, prior
to such transfer, furnishes (or has furnished on its behalf by a U.S.
broker-dealer) to the Trustee (as defined in the Indenture) a signed letter
containing certain representations and agreements relating to the restrictions
on transfer of the Notes (the form of which letter can be obtained from the
Trustee), (iv) outside the United States in accordance with Rule 904 of
Regulation S promulgated under the Securities Act to non-U.S. persons, (v)
pursuant to the exemption from registration provided by Rule 144 under the
Securities Act (if available), or (vi) pursuant to an effective registration
statement under the Securities Act, and we further agree to provide to any
person purchasing any of the Notes from us a notice advising such purchaser that
resales of the Notes are restricted as stated herein.

     4.   We understand that, on any proposed resale of any Notes, we will be
required to furnish to the Trustee and the Company such certification, legal
opinions and other information as the Trustee and the Company may reasonably
require to confirm that the proposed sale complies with the foregoing
restrictions.  We further understand that the Notes purchased by us will bear a
legend to the foregoing effect.

     5.   We are an institutional "accredited investor" (as defined in Rule
501(a)(1), (2), (3) or (7) of Regulation D under the Securities Act) and have
such knowledge and experience in financial and business matters as to be capable
of evaluating the merits and risks of our investment in the Notes, and we and
any accounts for which we are acting are each able to bear the economic risk of
our or their investment, as the case may be.

     6.   We are acquiring the Notes purchased by us for our account or for one
or more accounts (each of which is an institutional "accredited investor") as to
each of which we exercise sole investment discretion.

     States;

          (2)  either (a) at the time the buy offer was originated, the

     States, or (b) the transaction was executed in, on or through the
     facilities of a designated off-shore securities market and neither we nor
     any person acting on our behalf knows that the transaction has been
     pre-arranged with a buyer in the United States;

          (3)  no directed selling efforts have been made in the United States
     in contravention of the requirements of Rule 903(b) or Rule 904(b) of
     Regulation S, as applicable;

          (4)  the transaction is not part of a plan or scheme to evade the
