   The undersigned acknowledges receipt of the Prospectus, dated       , 2000
(as it may be supplemented and amended from time to time the "Prospectus") of
ChipPAC International Limited (the "Company") and this Letter of Transmittal
(the "Letter of Transmittal"), which together describe the Company's offer
(the "Exchange Offer") to exchange $1,000 principal amount of its 12 3/4%
Series B Senior Subordinated Notes due 2009 (the "Exchange Notes"), which have
been registered under the Securities Act of 1933, as amended (the "Securities
Act"), pursuant to a Registration Statement, for each $1,000 principal amount
of its outstanding 12 3/4% Senior Subordinated Notes due 2009 (the "Notes"),
of which $150,000,000 principal amount is outstanding. The term "Expiration
Date" shall mean 5:00 p.m., New York City time, on       , 2000, unless the
Company, in its sole discretion, extends the Exchange Offer, in which case the
term shall mean the latest date and time to which the Exchange Offer is
extended. The term "Holder" with respect to the Exchange Offer means any
person in whose name Notes are registered on the books of the Company or any
other person who has obtained a properly completed bond power from the
registered holder. Capitalized terms used but not defined herein have the
respective meanings set forth in the Prospectus.

   This Letter of Transmittal is to be used by holders of Notes if (i)
certificates representing the Notes are to be physically delivered to the
Exchange Agent herewith, (ii) tender of the Notes is to be made by book-entry


transfer to the Exchange Agent's account at The Depository Trust Company (the
"Book-Entry Transfer Facility") pursuant to the procedures set forth in the
Prospectus under the caption "The Exchange Offer--Procedures for Tendering" by
any financial institution that is a participant in the Book-Entry Transfer
Facility and whose name appears on a security position listing as the owner of
Notes to the extent provided herein or (iii) tender of the Notes is to be made
according to the guaranteed delivery procedures described in the Prospectus
under the caption "The Exchange Offer--Guaranteed Delivery Procedures." See
Instruction 2 below. Delivery of documents to the Book-Entry Transfer Facility
does not constitute delivery to the Exchange Agent.

   Notwithstanding the foregoing, valid acceptance of the terms of the
Exchange Offer may be effected by a participant in the Book-Entry Transfer
Facility tendering Notes through the Book-Entry Transfer Facility's Automated
Tender Offer Program ("ATOP") where the Exchange Agent receives an Agent's
Message prior to the Expiration Date. Accordingly, such participant must
electronically transmit its acceptance to the Book-Entry Transfer Facility
through ATOP, and then the Book-Entry Transfer Facility will edit and verify
the acceptance, execute a book-entry delivery to the Exchange Agent's account
at the Book-Entry Transfer Facility and send an Agent's Message to the
Exchange Agent for its acceptance. By tendering through ATOP, participants in
the Book-Entry Transfer Facility will expressly acknowledge receipt of this
Letter of Transmittal and agree to be bound by its terms and the Company will
be able to enforce such agreement against such Book-Entry Transfer Facility
participants.

   The undersigned has completed, executed and delivered this Letter of
Transmittal to indicate the action the undersigned desires to take with
respect to the Exchange Offer. Holders who wish to tender their Notes must
complete this letter in its entirety.

                    NOTE: SIGNATURES MUST BE PROVIDED BELOW
                PLEASE READ ACCOMPANYING INSTRUCTIONS CAREFULLY

Ladies and Gentlemen:

   Subject to the terms and conditions of the Exchange Offer, the undersigned
hereby tenders to the Company, the principal amount of Notes indicated above.

   Subject to and effective upon the acceptance for exchange of the principal
amount of Notes tendered in accordance with this Letter of Transmittal, the
undersigned sells, assigns and transfers to, or upon the order of, the Company
all right, title and interest in and to the Notes tendered hereby. The
undersigned hereby irrevocably constitutes and appoints the Exchange Agent its
agent and attorney-in-fact (with full knowledge that the Exchange Agent also
acts as the agent of the Company) with respect to the tendered Notes with the
full power of substitution to (i) present such Notes and all evidences of
transfer and authenticity to, or transfer ownership of, such Notes on the
account books maintained by the Book-Entry Transfer Facility to, or upon the
order of, the Company, (ii) deliver certificates for such Notes to the Company
and deliver all accompanying evidences of transfer and authenticity to, or
upon the order of, the Company and (iii) present such Notes for transfer on
the books of the Company and receive all benefits and otherwise exercise all
rights of beneficial ownership of such Notes, all in accordance with the terms
of the Exchange Offer.

   The undersigned hereby represents and warrants that the undersigned has
full power and authority to tender, sell, assign and transfer the Notes
tendered hereby and that the Company will acquire good, valid and unencumbered
title thereto, free and clear of all liens, restrictions, charges and
encumbrances and not subject to any adverse claims, when the same are acquired
by the Company. The undersigned hereby further represents that any Exchange
Notes acquired in exchange for Notes tendered hereby will have been acquired
in the ordinary course of business of the person receiving such Exchange
Notes, whether or not such person is the undersigned, that neither the
undersigned nor any other such person has any arrangement or understanding
with any person to participate in the distribution of such Exchange Notes and
that neither the undersigned nor any such other person is an "affiliate," as
defined in Rule 405 under the Securities Act, of the Company. In addition, the
undersigned and any such person acknowledge that (a) any person participating
in the Exchange Offer for the purpose of distributing the Exchange Notes must,
in the absence of an exemption therefrom, comply with the registration and
prospectus delivery requirements of the Securities Act in connection with a
secondary resale of the Exchange Notes and cannot rely on the position of the
staff of the Securities and Exchange Commission enunciated in no-action
letters and (b) failure to comply with such requirements in such instance
could result in the undersigned or such person incurring liability under the
Securities Act for which the undersigned or such person is not indemnified by
the Company. The undersigned will, upon request, execute and deliver any
additional documents deemed by the Exchange Agent or the Company to be
necessary or desirable to complete the assignment, transfer and purchase of
the Notes tendered hereby. If the undersigned is not a broker-dealer, the
undersigned represents that it is not engaged in and does not intend to engage
in, a distribution of Exchange Notes. If the undersigned is a broker-dealer
that will receive Exchange Notes for its own account in exchange for Notes
that were acquired as a result of market-making activities or other trading
activities, it acknowledges that it will deliver a Prospectus in connection
with any resale of such Exchange Notes, however, by so acknowledging and by
delivering a Prospectus, the undersigned will not be deemed to admit that it
is an "underwriter" within the meaning of the Securities Act. Unless otherwise
notified in accordance with the instructions set forth herein in Box 4 under
"Broker-Dealer Status," the Company will assume that the undersigned is not a
Participating Broker-Dealer.

   For purposes of the Exchange Offer, the Company shall be deemed to have
accepted validly tendered Notes when, as and if the Company has given notice
thereof to the Exchange Agent (such notice if given orally, to be confirmed in
writing).

   If any Notes tendered herewith are not accepted for exchange pursuant to
the Exchange Offer for any reason, certificates for any such unaccepted Notes
will be returned, without expense, to the undersigned at the address shown
below or to a different address as may be indicated herein in Box 3 under
"Special Delivery Instructions" as promptly as practicable after the
Expiration Date.

                                       4


   All authority conferred or agreed to be conferred by this Letter of
Transmittal shall survive the death, incapacity or dissolution of the
undersigned, and every obligation of the undersigned under this Letter of
Transmittal shall be binding upon the undersigned's heirs, personal
representative, successors and assigns.

   The undersigned understands that tenders of Notes pursuant to the
procedures described under the caption "The Exchange Offer--Procedures for
Tendering" in the Prospectus and in the instructions hereto will constitute a
binding agreement between the undersigned and the Company upon the terms and
subject to the conditions of the Exchange Offer, subject only to withdrawal of
such tenders on the terms set forth in the Prospectus under the caption "The
Exchange Offer--Withdrawal of Tenders."

   Unless otherwise indicated in Box 2 under "Special Registration
Instructions," please issue the certificates representing the Exchange Notes
issued in exchange for the Notes accepted for exchange and any certificates
for Notes not tendered or not exchanged, in the name(s) of the registered
holder of the Notes appearing in Box 1 above. Similarly, unless otherwise
indicated in Box 3 under "Special Delivery Instructions," please send the
certificates, if any, representing the Exchange Notes issued in exchange for
the Notes accepted for exchange and any certificates for Notes not tendered or
not exchanged (and accompanying documents, as appropriate) to the undersigned
at the address shown below in the undersigned's signature(s). In the event
that the box entitled "Special Registration Instructions" and the box entitled
"Special Delivery Instructions" both are completed, please issue the
certificates representing the Exchange Notes issued in exchange for the Notes
accepted for exchange in the name(s) of, and return any certificates for Notes
not tendered or not exchanged to, the person(s) so indicated. The undersigned
understands that the Company has no obligation pursuant to the "Special
Registration Instructions" and "Special Delivery Instructions" to transfer any
Notes from the name of the registered Holder(s) thereof if the Company does
not accept for exchange any of the Notes so tendered.

   Holders who wish to tender their Notes and (i) whose Notes are not
immediately available or (ii) who cannot deliver the Notes, an Agent's
Message, this Letter of Transmittal or any other documents required hereby to
the Exchange Agent prior to the Expiration Date, may tender their Notes
according to the guaranteed delivery procedures set forth in the Prospectus
under the caption "The Exchange Offer--Guaranteed Delivery Procedures." See
Instruction 2 below.

                                       5

name(s) appear(s) on the Notes or by person(s) authorized to become registered
holder(s) by a properly completed bond power from the registered holder(s), a
copy of which must be transmitted with this Letter of Transmittal. If Notes to
which this Letter of Transmittal relates are held of record by two or more

                                 INSTRUCTIONS

                   FORMING PART OF THE TERMS AND CONDITIONS
                             OF THE EXCHANGE OFFER

   1. DELIVERY OF THIS LETTER OF TRANSMITTAL AND CERTIFICATES FOR NOTES OR
BOOK-ENTRY CONFIRMATIONS. Certificates representing the tendered Notes (or a
confirmation of book-entry transfer of such Notes into the Exchange Agent's
account with the Book-Entry Transfer Facility), as well as a properly
completed and duly executed copy of this Letter of Transmittal (or, in the
case of a book-entry transfer, an Agent's Message), a Substitute Form W-9 and
any other documents required by this Letter of Transmittal must be received by
the Exchange Agent at its address set forth herein prior to the Expiration
Date. The method of delivery of certificates for Notes and all other required
documents is at the election and sole risk of the tendering holder and
delivery will be deemed made only when actually received by the Exchange
Agent. If delivery is by mail, registered mail with return receipt requested,
properly insured, is recommended. As an alternative to delivery by mail, the
holder may wish to use an overnight or hand delivery service. In all cases,
sufficient time should be allowed to assure timely delivery. Neither the
Company nor the Exchange Agent is under an obligation to notify any tendering
holder of the Company's acceptance of tendered Notes prior to the completion
of the Exchange Offer.

   2. GUARANTEED DELIVERY PROCEDURES. Holders who wish to tender their Notes
but whose Notes are not immediately available and who cannot deliver their
certificates for Notes (or comply with the procedures for book-entry transfer
prior to the Expiration Date), the Letter of Transmittal and any other
documents required by the Letter of Transmittal to the Exchange Agent prior to
the Expiration Date must tender their Notes according to the guaranteed
delivery procedures set forth below. Pursuant to such procedures:

     (i) such tender must be made by or through a firm which is a member of a
  registered national securities exchange or of the National Association of
  Securities Dealers, Inc., or a commercial bank or trust company having an
  office or correspondent in the United States (an "Eligible Institution");

     (ii) prior to the Expiration Date, the Exchange Agent must have received
  from the holder and the Eligible Institution a properly completed and duly
  executed Notice of Guaranteed Delivery (by facsimile transmission, mail, or
  hand delivery) setting forth the name and address of the holder, the
  certificate number or numbers of the tendered Notes, and the principal
  amount of tendered Notes and stating that the tender is being made thereby
  and guaranteeing that, within three New York Stock Exchange trading days
  after the Expiration Date, the Letter of Transmittal (or facsimile thereof)
  (or, in the case of a book-entry transfer, an Agent's Message), together
  with the tendered Notes (or a confirmation of book-entry transfer of such
  Notes into the Exchange Agent's account with the Book-Entry Transfer
  Facility) and any other required documents will be deposited by the
  Eligible Institution with the Exchange Agent; and

     (iii) the certificates representing the tendered Notes in proper form
  for transfer (or a confirmation of book-entry transfer of such Notes into
  the Exchange Agent's account with the Book-Entry Transfer Facility),
  together with this Letter of Transmittal (or facsimile thereof), properly
  completed and duly executed, with any required signature guarantees (or, in
  the case of a book-entry transfer, an Agent's Message) and all other
  documents required by the Letter of Transmittal must be received by the
  Exchange Agent within three New York Stock Exchange trading days after the
  Expiration Date.

   Failure to complete the guaranteed delivery procedures outlined above will
not, of itself, affect the validity or effect a revocation of any Letter of
Transmittal form properly completed and executed by a Holder who attempted to
use the guaranteed delivery procedure.

   3. TENDER BY HOLDER. Only a registered holder of Notes may tender such
Notes in the Exchange Offer. Any beneficial owner of Notes who is not the
registered holder and who wishes to tender should arrange with such Holder to
execute and deliver this Letter of Transmittal on such owner's behalf or must,
prior to completing and executing this Letter of Transmittal and delivering
such Notes, either make appropriate arrangements to register ownership of the
Notes in such owner's name or obtain a properly completed bond power from the
registered holder.

                                       7


   4. PARTIAL TENDERS. Tenders of Notes will be accepted only in integral
multiples of $1,000 in principal amount. If less than the entire principal
amount of Notes is tendered, the tendering holder should fill in the principal
amount tendered in the column labeled "Principal Amount Tendered" of the box
entitled "Description of Notes" (Box 1) above. The entire principal amount of
Notes delivered to the Exchange Agent will be deemed to have been tendered
unless otherwise indicated. If the entire principal amount of Notes is not
tendered, Notes for the principal amount of Notes not tendered and Exchange
Notes exchanged for any Notes tendered will be sent to the holder at his or
her registered address, unless a different address is provided in the
appropriate box on this Letter of Transmittal, as soon as practicable
following the Expiration Date.

   5. SIGNATURES ON THE LETTER OF TRANSMITTAL; BOND POWERS AND ENDORSEMENTS;
MEDALLION GUARANTEE OF SIGNATURE. If this Letter of Transmittal is signed by
the registered holder(s) of the Notes tendered herewith, the signatures must
correspond with the name(s) as written on the face of the tendered Notes
without alteration, enlargement, or any change whatsoever.

   If any of the tendered Notes are owned of record by two or more joint
owners, all such owners must sign this Letter of Transmittal. If any tendered
Notes are held in different names on several Notes, it will be necessary to
complete, sign, and submit as many separate copies of the Letter of
Transmittal documents as there are names in which tendered Notes are held.

   If this Letter of Transmittal is signed by the registered holder, and
Exchange Notes are to be issued and any untendered or unaccepted principal
amount of Notes are to be reissued or returned to the registered holder, then,
the registered holder need not and should not endorse any tendered Notes nor
provide a separate bond power. In any other case, the registered holder must
either properly endorse the Notes tendered or transmit a properly completed
separate bond power with this Letter of Transmittal (executed exactly as the
name(s) of the registered holder(s) appear(s) on such Notes), with the
signature(s) on the endorsement or bond power guaranteed by an Eligible
Institution unless such certificates or bond powers are signed by an Eligible
Institution.

   If this Letter of Transmittal or any Notes or bond powers are signed by
trustees, executors, administrators, guardians, attorneys-in-fact, officers of
corporations, or others acting in a fiduciary or representative capacity, such
persons should so indicate when signing and evidence satisfactory to the
Company of their authority to so act must be submitted with this Letter of
Transmittal.

   No medallion signature guarantee is required if this Letter of Transmittal
is signed by the registered holder(s) of the Notes tendered herewith and the
Exchange Notes (and any Notes not tendered or not accepted) are to be issued
directly to such registered holder(s) and neither the "Special Registration
Instructions" (Box 2) nor the "Special Delivery Instructions" (Box 3) has been
completed. In all other cases, all signatures on this Letter of Transmittal
must be guaranteed by an Eligible Institution.

   6. SPECIAL REGISTRATION AND DELIVERY INSTRUCTIONS. Tendering holders should
indicate, in the applicable box, the name and address in which the Exchange
Notes and/or substitute Notes for principal amounts not tendered or not
accepted for exchange are to be sent, if different from the name and address
or account of the person signing this Letter of Transmittal. In the case of
issuance in a different name, the employer identification number or social
security number of the person named must also be indicated and the tendering
holders should complete the applicable box.

   If no such instructions are given, the Exchange Notes (and any Notes not
tendered or not accepted) will be issued in the name of and sent to the
registered holder of the Notes.

   7. TRANSFER TAXES. The Company will pay all transfer taxes, if any,
applicable to the sale and transfer of Notes to it or its order pursuant to
the Exchange Offer. If, however, a transfer tax is imposed for any reason
other than the transfer and sale of Notes to the Company or its order pursuant
to the Exchange Offer, then the amount of any such transfer taxes (whether
imposed on the registered holder or on any other person) will be payable by
the tendering holder. If satisfactory evidence of payment of such taxes or
exemption from taxes therefrom is not submitted with this Letter of
Transmittal, the amount of transfer taxes will be billed directly to such
tendering holder.

                                       8


   Except as provided in this Instruction 7, it will not be necessary for
transfer tax stamps to be affixed to the Notes listed in this Letter of
Transmittal.

   8. TAX IDENTIFICATION NUMBER. Federal income tax law required that a holder
of any Notes which are accepted for exchange must provide the Company (as
payer) with its correct taxpayer identification number ("TIN"), which, in the
case of a holder who is an individual, is his or her social security number.
If the Company is not provided with the correct TIN, the Holder may be subject
to a $50 penalty imposed by Internal Revenue Service. (If withholding results
in an over-payment of taxes, a refund may be obtained.) Certain holders
(including, among other, all corporations and certain foreign individuals) are
not subject to these backup withholding and reporting requirements. See the
enclosed "Guidelines for Certification of Taxpayer Identification Number on
Substitute Form W-9" for additional instructions.

   To prevent backup withholding, each tendering holder must provide such
holder's correct TIN by completing the Substitute Form W-9 set forth herein,
certifying that the TIN provided is correct (or that such holder is awaiting a
TIN), and that (i) the holder has not been notified by the Internal Revenue
Service that such holder is subject to backup withholding as a result of
failure to report all interest or dividends or (ii) the Internal Revenue
Service has notified the holder that such holder is no longer subject to
backup withholding. If the Notes are registered in more than one name or are
not in the name of the actual owner, see the enclosed "Guidelines for
Certification of Taxpayer Identification Number on Substitute Form W-9" for
information on which TIN to report.

   The Company reserves the right in its sole discretion to take whatever
steps are necessary to comply with the Company's obligation regarding backup
withholding.

   9. VALIDITY OF TENDERS. All questions as to the validity, form, eligibility
(including time of receipt), and acceptance of tendered Notes will be
determined by the Company, in its sole discretion, which determination will be
final and binding. The Company reserves the right to reject any and all Notes
not validly tendered or any Notes, the Company's acceptance of which would, in
the opinion of the Company or its counsel, be unlawful. The Company also
reserves the right to waive any conditions of the Exchange Offer or defects or
irregularities in tenders of Notes as to any ineligibility of any holder who
seeks to tender Notes in the Exchange Offer. The interpretation of the terms
and conditions of the Exchange Offer (including this Letter of Transmittal and
the instructions hereto) by the Company shall be final and binding on all
parties. Unless waived, any defects or irregularities in connection with
tenders of Notes must be cured within such time as the Company shall
determine. The Company will use reasonable efforts to give notification of
