     SECTION 3. Agreement. The Company and ChipPAC hereby agree as follows:

          (a) The Company and ChipPAC will use reasonable efforts to issue or
     cause to be issued Permitted Junior Capital on or prior to the Prepayment
     Transactions Date, in an amount sufficient to raise at least $20,000,000 of
     Net Proceeds (as defined below). If such Permitted Junior Capital is issued
     by the Company or ChipPAC prior to the Prepayment Transactions Date, then
     on or prior to the first Business Day following the receipt of such Net
     Proceeds, the Company will prepay the outstanding Term Loans in an
     aggregate principal amount equal to the greater of (i) $20,000,000 and (ii)
     50% of the amount of such Net Proceeds, such prepayment to be applied as
     specified for mandatory prepayments in Subsection 2.4(c) of the Credit
     Agreement. The Required Lenders hereby consent to the foregoing prepayment
     requirement and waive compliance by the Company and ChipPAC with
     Subsections 2.4B(iii)(b) and (c) to the extent such subsections would
     require the application of a greater percentage of the Net Proceeds of
     Permitted Junior Capital issued on or prior to the Prepayment Transactions
     Date, to be applied to the prepayment of the Term Loans.

          (b) As used herein, the following terms shall have the meanings
     specified below:

               "Net Proceeds" shall mean (a) with respect to any issuance of
          Permitted Junior Capital constituting Capital Stock or other equity
          securities, the Equity Proceeds thereof, and (b) with respect to any
          issuance of Permitted Junior Capital constituting Indebtedness, the
          gross cash proceeds thereof (net of any payment of underwriting
          discounts, commissions and other costs and expenses associated
          therewith (including legal costs and expenses)).

               "Permitted Junior Capital" shall mean (a) Capital Stock of

          to the maturity date of the Convertible Subordinated Notes issued
          prior to the Amendment Effective Date (as defined below) and (ii) the
          subordination provisions (in the case of Indebtedness) and other
          non-pricing terms and conditions thereof are no less favorable to
          ChipPAC and its Subsidiaries and the Lenders than the analogous
          provisions of the Subordinated Debt Documents issued prior to the
          Amendment Effective Date.

               "Prepayment Transactions" shall mean, collectively, the issuance
          of the Permitted Junior Capital and the prepayment of the Term Loans
          as required by Section 3 hereof.

Commitment (whether used or unused) and outstanding Term Loans, in each case as
of the Amendment Effective Date. The Amendment Fee shall be payable in
immediately available funds on the Amendment Effective Date. Once paid, the
Amendment Fee shall not be refundable.

"The shares of [Common or Preferred] Stock represented by this certificate are
subject to restrictions on transfer for the purpose of the Company's maintenance
of its status as a real estate investment trust under the Internal Revenue Code
of 1986, as amended (the "Code"), and for certain other purposes under the Code
and the Employee Retirement Income Security Act of 1974, as amended ("ERISA").
No person may (i) Beneficially Own or Constructively Own shares of Common Stock
in excess of 9.9% of the number of outstanding shares of Common Stock, (ii)
Beneficially Own or Constructively Own shares of any class or series of
Preferred Stock in excess of 9.9% of the number of outstanding shares of such
class or series of Preferred Stock, (iii) beneficially own shares of Equity
Stock that would result in the shares of Equity Stock being beneficially owned
by fewer than 100 Persons (determined without reference to any rules of
attribution), (iv) Beneficially own shares of Equity Stock that would result in
the Company being "closely held" within the meaning of Section 856(h) of the
Code, (v) Constructively Own shares of Equity Stock that would cause the Company
to Constructively Own 10% or more of the ownership interests in a tenant of the
Company's real property, within the meaning of Section 856(d)(2)(B) of the Code,
or (vi) Beneficially Own shares of Equity Stock that would result in 25% or more
of any class of the Equity Stock being Beneficially Owned by one or more ERISA
Investors. Any person who attempts to Beneficially Own or Constructively Own
shares of Equity Stock in excess of the above limitations must immediately
notify the Company in writing. If the restrictions above are violated, the
shares of [Common or Preferred] Stock represented hereby will be transferred
automatically and by operation of law to a Trust and shall be designated
Share-in-Trust. All capitalized terms in this legend have the meanings defined
in the Company's Articles of Incorporation, as the same may be further amended
and restated from time to time, a copy of which, including the restrictions on
transfer, will be sent without charge to each shareholder who so requests."
