                           [FORM OF FACE OF SECURITY]

[Unless this certificate is presented by an authorized representative of the
Depository Trust Company to the Company or its agent for registration of
transfer, exchange or payment, and any certificate issued is registered in the
name of Cede & Co. or in such other name as is requested by an authorized
representative of the Depository Trust Company (and any payment hereon is made
to Cede & Co. or to such other entity as is requested by an authorized
representative of the depository trust company), any transfer, pledge or other
use hereof for value or otherwise by or to any person is wrongful since the
registered owner hereof, Cede & Co., has an interest herein. This security is a
Global Security within the meaning of the Indenture hereinafter referred to and
is registered in the name of a depositary or a nominee thereof. This security is
exchangeable for securities registered in the name of a person other than the
depositary or its nominee only in the limited circumstances described in the
Indenture and, unless and until it is exchanged in whole or in part for
securities in definitive form, this security may not be transferred except as a
whole by the depositary to a nominee of the depositary or by a nominee of the
depositary to the depositary or another nominee of the depositary or by the
depositary or any such nominee to a successor depositary or a nominee of such
successor depositary.]/1/

[This security (or its predecessor) was originally issued in a transaction
exempt from registration under the United States Securities Act of 1933, as
amended (the "Securities Act"), and this security and the shares of common stock
issuable upon conversion thereof may not be offered, sold or otherwise
transferred in the absence of such registration or an applicable exemption
therefrom. Each purchaser of this security is hereby notified that the seller of
this security may be relying on the exemption from the provisions of Section 5
of the Securities Act provided by Rule 144A thereunder.]/2/

[The holder of this security agrees for the benefit of the company that (a) this
security and the shares of common stock issuable upon conversion thereof may be
offered, resold, pledged or otherwise transferred, only [(i) in the United
States to a person whom the seller reasonably believes is a qualified
institutional buyer (as defined in Rule 144A under the Securities Act) in a
transaction meeting the requirements of Rule 144A,] (ii) outside the United
States in an offshore transaction in accordance with Rule 904 under the
Securities Act, (iii) pursuant to an exemption from registration under the
Securities Act provided by Rule 144 thereunder (if available) or (iv) pursuant
to an effective registration statement under the Securities Act, in each of
cases (i) through (iv) in accordance with any applicable securities laws of any
state of the United States, and (b) the holder will, and each subsequent holder
is required to, notify any purchaser of this security from it of the resale
restrictions referred to in (a) above. In any case, the holder hereof

will not, directly or indirectly, engage in any hedging transactions with regard
to this security except as permitted under the Securities Act.]/2/

[The holder of this security is entitled to the benefits of a Registration
Rights Agreement (as such term is defined in the Indenture referred to on the
reverse hereof) and, by its acceptance hereof, agrees to be bound by and to
comply with the provisions of such Registration Rights Agreement.]/2/

This security may not be sold or transferred to, and each purchaser by its
purchase of this security shall be deemed to have represented and covenanted
that it is not acquiring this security for or on behalf of, and will not
transfer this security to, any pension or welfare plan as defined in Section
3(1) of the Employee Retirement Income Security Act of 1974, as amended
("ERISA") except that such purchase for or on behalf of a pension or welfare
plan shall be permitted:

          (i) to the extent such purchase is made by or on behalf of a bank
     collective investment fund maintained by the purchaser in which no plan
     (together with any other plans maintained by the same employer or employee
     organization) has an interest in excess of 10% of the total assets in such
     collective investment fund, and the other applicable conditions of
     Prohibited Transaction Class Exemption 91-38 issued by the Department of
     Labor are satisfied;

          (ii) to the extent such purchase is made by or on behalf of an

     organization) has an interest in excess of 10% of the total of all assets
     in such pooled separate account, and the other applicable conditions of
     Prohibited Transaction Class Exemption 90-1 issued by the Department of
     Labor are satisfied;

          (iii) to the extent such purchase is made on behalf of a plan by (A)

     fiscal year total assets under its management and control in excess of
     $50.0 million and had stockholders' or partners' equity in excess of
     $750,000, as shown in its most recent balance sheet prepared in accordance

     million as of the last day of its most recent fiscal year, or (C) an
     insurance company which is qualified under the laws of more than one state
     to manage, acquire or dispose of any assets of a pension or welfare plan,
     which insurance company has as of the last day of its most recent fiscal
     year, net worth in excess of $1.0 million and which is subject to
     supervision and examination by a State authority having supervision over
     insurance companies and, in any case, such investment adviser, bank or
     insurance company is otherwise a qualified professional asset manager, as
     such term is used in Prohibited Transaction Class Exemption 84-14 issued by
     the Department of Labor, and the assets of such plan when combined with the
     assets of other plans established or maintained by the same employer (or
     affiliate thereof) or employee organization and managed by such investment
     adviser, bank or insurance company, do not represent more than 20% of the
     total client assets managed by such investment adviser, bank or insurance
     company at the time of the transaction, and the other applicable conditions
     of such exemption are otherwise satisfied;

          (iv) to the extent such plan is a governmental plan (as defined as
     Section 3(33) of ERISA) which is not subject to the provisions of Title 1
     of ERISA or Section 401 of the Internal Revenue Code of 1986, as amended

     (exclusive of separate account liabilities), plus surplus as set forth in
     the National Association of Insurance Commissioners Annual Statement filed
     with the state of domicile of the insurer, in accordance with Prohibited
     Transaction Class Exemption 95-60, and the other applicable conditions of
     such exemption are otherwise satisfied;

          (vi) to the extent purchase is made by an in-house asset manager
     within the meaning of Part IV(a) of Prohibited Transaction Class Exemption

               8% CONVERTIBLE SUBORDINATED NOTES DUE JUNE 15, 2011

1.   Interest
     --------

ChipPAC, Inc. a Delaware corporation (the "Company", which term shall include
any successor corporation under the Indenture hereinafter referred to), promises
to pay interest on the principal amount of this Security at the rate of 8% per
annum. The Company shall pay interest semiannually on June 15 and December 15 of
each year, commencing December 15, 2001. Interest on the Securities shall accrue
from the most recent date to which interest has been paid or, if no interest has
been paid, from June 22, 2001; provided, however, that if there is not an
                               --------  -------
existing Default in the payment of interest and if this Security is
authenticated between a record date referred to on the face hereof and the next
succeeding interest payment date, interest shall accrue from such interest
payment date. Interest will be computed on the basis of a 360-day year of twelve
30-day months. Any reference herein to interest accrued or payable as of any
date shall include any Additional Interest accrued or payable on such date as
provided in the Registration Rights Agreement.

2.   Method of Payment
     -----------------

The Company shall pay interest on this Security (except defaulted interest) to
the person who is the Holder of this Security at the close of business on June 1
or December 1, as the case may be, next preceding the related interest payment
date. The Holder must surrender this Security to a Paying Agent to collect
payment of principal. The Company will 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. The Company may, however, pay principal and interest
in respect of any Certificated Security by check or wire payable in such money;
provided, however, that a Holder with an aggregate principal amount in excess of
--------  -------
$2,000,000 will be paid by wire transfer in immediately available funds at the
election of such Holder. The Company may mail an interest check to the Holder's
registered address. Notwithstanding the foregoing, so long as this Security is
registered in the name of a Depositary or its nominee, all payments hereon shall
be made by wire transfer of immediately available funds to the account of the
Depositary or its nominee.

3.   Paying Agent, Registrar and Conversion Agent
     --------------------------------------------

Initially, Firstar Bank, N.A. (the "Trustee", which term shall include any
successor trustee under the Indenture hereinafter referred to) will act as
Paying Agent, Registrar, Primary Registrar and Conversion Agent. The Company may
change any Paying Agent, Registrar or Conversion Agent without notice to the
Holder. The Company or any of its Subsidiaries may, subject to certain
limitations set forth in the Indenture, act as Paying Agent or Registrar.

4.   Indenture, Limitations
     ----------------------


                                       6

<PAGE>

This Security is one of a duly authorized issue of Securities of the Company
designated as its 8% Convertible Subordinated Notes Due June 15, 2011 (the
"Securities"), issued under an Indenture dated as of June 15, 2001 (together
with any supplemental indentures thereto, the "Indenture"), between the Company
and the Trustee. Capitalized terms herein are used as defined in the Indenture
unless otherwise defined herein. The terms of this Security include those stated
in the Indenture and those required by or made part of the Indenture by
reference to the Trust Indenture Act of 1939, as amended, as in effect on the
date of the Indenture. This Security is subject to all such terms, and the
Holder of this Security is referred to the Indenture and said Act for a
statement of them. The Securities are subordinated unsecured obligations of the
Company. Subject to the conditions set forth in Section 2.15 of the Indenture,
the Company may issue additional Securities ("Add On Securities"). The Indenture
does not limit other debt of the Company, secured or unsecured, including Senior
Indebtedness.

5.   Provisional and Optional Redemption
     -----------------------------------

     (a) The Company may redeem any portion of the Securities at any time prior
to June 15, 2004 (a "Provisional Redemption"), upon giving notice as set forth
in Section 6, at a redemption price equal to $1,000 per $1,000 principal amount
of the Securities redeemed plus accrued and unpaid interest, if any (such
amount, the "Provisional Redemption Price"), to but excluding the date of
redemption (the "Provisional Redemption Date") if (1) the Closing Price of the
Common Stock has exceeded 150% of the Conversion Price for at least 20 Trading
Days within a period of any 30 consecutive Trading Days ending on the Trading
Day prior to the date of mailing of the notice of Provisional Redemption (the
"Notice Date"), and (2) a shelf registration statement covering resales of the
Securities and the Common Stock issuable upon conversion thereof is effective
and available for use and is expected to remain effective and available for use
for the 30 days following the Provisional Redemption Date unless registration is
no longer required.

          (b) Except as set forth in clause (a) of this Section 5, the Company
shall not have the option to redeem the Securities pursuant to this Section 5
prior to June 15, 2004. Thereafter, the Company shall have the option to redeem
any portion of the Securities (an "Optional Redemption") upon giving notice as
set forth in Section 6. The Optional Redemption Prices (expressed as percentages
of the principal amount) are as follows for Securities redeemed during the
periods set forth below:

Period                                                        Redemption Price
------                                                        ----------------
Beginning on June 15, 2004 and ending on June 14, 2005        104.00%
Beginning on June 15, 2005 and ending on June 14, 2006        103.33%
Beginning on June 15, 2006 and ending on June 14, 2007        102.67%
Beginning on June 15, 2007 and ending on June 14, 2008        102.00%
Beginning on June 15, 2008 and ending on June 14, 2009        101.33%
Beginning on June 15, 2009 and ending on June 14, 2010        100.67%
Beginning on June 15, 2010 and thereafter                     100.00%


                                       7

<PAGE>

in each case together with accrued interest up to but not including the date of
redemption (the "Optional Redemption Date"); provided that if the Optional
                                             --------
Redemption Date falls after an interest payment record date and on or before an
interest payment date, then the interest payment will be payable to the Holders
in whose names the Securities are registered at the close of business on the
relevant record date for payment of such interest.

6.   Notice of Redemption
     --------------------

Notice of redemption will be mailed by first-class mail at least 20 days but not
more than 60 days before the Redemption Date to each Holder of Securities to be
redeemed at its registered address. Securities in denominations larger than
$1,000 may be redeemed in part, but only in whole multiples of $1,000. On and
after the Redemption Date, subject to the deposit with the Paying Agent of funds
sufficient to pay the Redemption Price plus accrued interest, if any, accrued
to, but excluding, the Redemption Date, interest shall cease to accrue on
Securities or portions of them called for redemption.

7.   Purchase of Securities at Option of Holder Upon a Change in Control
     -------------------------------------------------------------------

At the option of the Holder and subject to the terms and conditions of the
Indenture, the Company shall become obligated to purchase all or any part
specified by the Holder (so long as the principal amount of such part is $1,000
or an integral multiple of $1,000 in excess thereof) of the Securities held by
such Holder on the date that is not less than 20 nor more than 30 Business Days
after the date on which the Company provides Holders notice of the occurrence of
a Change in Control (or, if the Company has not provided such, 40 Business Days
following the occurrence of a Change of Control), at a purchase price equal to
100% of the principal amount thereof together with accrued interest up to, but
excluding, the Change in Control Purchase Date. The Holder shall have the right
to withdraw any Change in Control Purchase Notice (in whole or in a portion
thereof that is $1,000 or an integral multiple of $1,000 in excess thereof) at
any time prior to the close of business on the Business Day next preceding the
Change in Control Purchase Date by delivering a written notice of withdrawal to
the Paying Agent in accordance with the terms of the Indenture.

8.   Conversion
     ----------

A Holder of a Security may convert the principal amount of such Security (or any
portion thereof equal to $1,000 or any integral multiple of $1,000 in excess
thereof) into shares of Common Stock at any time prior to the close of business
on June 15, 2011; provided, however, that if the Security is called for
                  --------  -------
redemption or subject to purchase upon a Change in Control, the conversion right
will terminate at the close of business on the Business Day immediately
preceding the Redemption Date or the Change in Control Purchase Date, as the
case may be, for such Security or such earlier date as the Holder presents such
Security for redemption or purchase (unless the Company shall default in making
the redemption payment or Change in Control Purchase Price, as the case may be,
when due, in which case the conversion right shall terminate at the close of
business on the date such default is cured and such Security is redeemed or
purchased). The initial Conversion Price is $9.96 per share, subject to
adjustment under certain circumstances. The number of shares of Common Stock
issuable upon conversion of a Security is determined by dividing the principal
amount of the Security or portion thereof converted by the Conversion Price in
effect on the Conversion Date. No fractional shares will be

                                       8

<PAGE>

issued upon conversion; in lieu thereof, an amount will be paid in cash based
upon the Closing Price (as defined in the Indenture) of the Common Stock on the
Trading Day immediately prior to the Conversion Date. To convert a Security, a
Holder must (a) complete and manually sign the conversion notice set forth below
and deliver such notice to a Conversion Agent, (b) surrender the Security to a
Conversion Agent, (c) furnish appropriate endorsements and transfer documents if
required by a Registrar or a Conversion Agent, and (d) pay any transfer or
similar tax, if required. Securities so surrendered for conversion (in whole or
in part) during the period from the close of business on any regular record date
to the opening of business on the next succeeding interest payment date
(excluding Securities or portions thereof which are either (i) called for
redemption or (ii) subject to purchase following a Change in Control, in either
case, on a date during the period beginning at the close of business on a
regular record date and ending at the opening of business on the first Business
Day after the next succeeding interest payment date, or if such interest payment
date is not a Business Day, the second such Business Day) shall also be
accompanied by payment in funds acceptable to the Company of an amount equal to
the interest payable on such interest payment date on the principal amount of
such Security then being converted, and such interest shall be payable to such
registered Holder notwithstanding the conversion of such Security, subject to
the provisions of this Indenture relating to the payment of defaulted interest
by the Company. Except as otherwise provided in this paragraph, no payment or
adjustment will be made for accrued interest on a converted Security. If the
Company defaults in the payment of interest payable on such interest payment
date, the Company shall promptly repay such funds to such Holder. A Holder may
convert a portion of a Security equal to $1,000 or any integral multiple
thereof. A Security in respect of which a Holder had delivered a Change in
Control Purchase Notice exercising the option of such Holder to require the
Company to purchase such Security may be converted only if the Change in Control
Purchase Notice is withdrawn in accordance with the terms of the Indenture.

9.   Conversion Arrangement on Call for Redemption
     ---------------------------------------------

Any Securities called for redemption, unless surrendered for conversion before
the close of business on the Business Day immediately preceding the Redemption
Date, may be deemed to be purchased from the Holders of such Securities at an
amount not less than the Redemption Price, together with accrued interest, if
any, to, but not including, the Redemption Date, by one or more investment
bankers or other purchasers who may agree with the Company to purchase such
Securities from the Holders, to convert them into Common Stock of the Company
and to make payment for such Securities to the Paying Agent in trust for such
Holders.

10.  Subordination
     -------------

The indebtedness evidenced by the Securities is, to the extent and in the manner
provided in the Indenture, subordinate and junior in right of payment to the
prior payment in full of all Senior Indebtedness of the Company. Any Holder by
accepting this Security agrees to and shall be bound by such subordination
provisions and authorizes the Trustee to give them effect. In addition to all
other rights of Senior Indebtedness described in the Indenture, the Senior
Indebtedness shall continue to be Senior Indebtedness and entitled to the
benefits of the subordination provisions irrespective of any amendment,
modification or waiver of any terms of

                                       9

<PAGE>

any instrument relating to the Senior Indebtedness or any extension or renewal
of the Senior Indebtedness.

11.  Denominations, Transfer, Exchange
     ---------------------------------

The Securities are in registered form without coupons in denominations of $1,000
and integral multiples of $1,000. A Holder may register the transfer of or
exchange Securities in accordance with the Indenture. The Registrar may require
a Holder, among other things, to furnish appropriate endorsements and transfer
documents and to pay any taxes or other governmental charges that may be imposed
in relation thereto by law or permitted by the Indenture.

12.  Persons Deemed Owners
     ---------------------

The Holder of a Security may be treated as the owner of it for all purposes.

13.  Unclaimed Money
     ---------------

If money for the payment of principal or interest remains unclaimed for two
years, the Trustee or Paying Agent will pay the money back to the Company at its
written request. After that, Holders entitled to money must look to the Company
for payment.

14.  Amendment, Supplement and Waiver
     --------------------------------

Subject to certain exceptions, the Indenture or the Securities may be amended or
supplemented with the consent of the Holders of at least a majority in principal
amount of the Securities then outstanding, and an existing Default or Event of
Default and its consequence or compliance with any provision of the Indenture or
the Securities may be waived in a particular instance with the consent of the
Holders of a majority in principal amount of the Securities then outstanding.
Without the consent of or notice to any Holder, the Company and the Trustee may
amend or supplement the Indenture or the Securities to, among other things, cure
any ambiguity, defect or inconsistency or make any other change that does not
adversely affect the rights of any Holder.

15.  Successor Corporation
     ---------------------

When a successor corporation assumes all the obligations of its predecessor
under the Securities and the Indenture in accordance with the terms and
conditions of the Indenture, the predecessor corporation will (except in certain
circumstances specified in the Indenture) be released from those obligations.

16.  Defaults and Remedies
     ---------------------

Under the Indenture, an Event of Default includes: (i) default for 30 days in
payment of any interest on any Securities; (ii) default in payment of any
principal (including, without limitation, any premium, if any) on the Securities
when due; (iii) failure by the Company for 60 days after notice to it to comply
with any of its other agreements contained in the Indenture or the Securities;
(iv) failure by the Company to give notice to the Trustee and Holders of a
Change in Control in accordance with the Indenture; and (v) certain events of
bankruptcy, insolvency or

                                       10

<PAGE>

reorganization of the Company. If an Event of Default (other than as a result
of certain events of bankruptcy, insolvency or reorganization of the Company)
occurs and is continuing, the Trustee or the Holders of at least 25% in
principal amount of the Securities then outstanding may declare all unpaid
principal to the date of acceleration on the Securities then outstanding to be
due and payable immediately, all as and to the extent provided in the Indenture.
If an Event of Default occurs as a result of certain events of bankruptcy,

                 OF TRANSFER OF TRANSFER RESTRICTED SECURITIES/5/
                 ---------------------------------------------


Re:  8% Convertible Subordinated Securities Due June 15, 2011
     (the "Securities") of ChipPAC, Inc.

This certificate relates to $_______ principal amount of Securities owned in
(check applicable box)

[ ] book-entry or [ ] definitive form by ________________ (the "Transferor").

     The Transferor has requested a Registrar or the Trustee to exchange or
register the transfer of such Securities.

     In connection with such request and in respect of each such Security, the
Transferor does hereby certify that the Transferor is familiar with transfer
restrictions relating to the Securities as provided in Section 2.12 of the
Indenture, dated as of June 15, 2001, between ChipPAC, Inc. and Firstar Bank,
N.A. (the "Indenture"), and the transfer of such Security is being made pursuant
to an effective registration statement under the Securities Act of 1933, as
amended (the "Securities Act") (check applicable box) or the transfer or
exchange, as the case may be, of such Security does not require registration
under the Securities Act because (check applicable box):

[ ]  Such Security is being transferred pursuant to an effective registration
statement under the Securities Act.

[ ]  Such Security is being acquired for the Transferor's own account, without
transfer.

[ ]  Such Security is being transferred to the Company or a Subsidiary (as
defined in the Indenture) of the Company.

[ ]  Such Security is being transferred to a person the Transferor reasonably
believes is a "qualified institutional buyer" (as defined in Rule 144A or any
successor provision thereto ("Rule 144A") under the Securities Act) that is
purchasing for its own account or for the account of a "qualified institutional
buyer", in each case to whom notice has been given that the transfer is being
made in reliance on such Rule 144A, and in each case in reliance on Rule 144A.

[ ]  Such Security is being transferred pursuant to and in compliance with an
exemption from the registration requirements under the Securities Act in
accordance with Rule 144 (or any successor thereto) ("Rule 144") under the
Securities Act.

[ ]  Such Security is being transferred pursuant to and in compliance with an
exemption from the registration requirements of the Securities Act (other than
an exemption referred to above) and as a result of which such Security will,
upon such transfer, cease to be a "restricted security" within the meaning of
Rule 144 under the Securities Act.

--------
/5/ This certificate should only be included if this Security is a Transfer
    Restricted Security.

<PAGE>
                                      -2-

     The Transferor acknowledges and agrees that, if the transferee will hold
any such Securities in the form of beneficial interests in a global Security
which is a "restricted security" within the meaning of Rule 144 under the
Securities Act, then such transfer can only be made pursuant to Rule 144A under
the Securities Act and such transferee must be a "qualified institutional buyer"
(as defined in Rule 144A).
