WHEREAS the Parties have entered into a Joint Venture Agreement on 13 November 2002.

WHEREAS the Parties have entered into a First Amendment to the Joint Venture Agreement on 3 December 2003 and a Second Amendment to the Joint Venture Agreement on 28 September 2004.

WHEREAS, the Parties have decided to change the status of Inotera Memories Inc. from a private to a public company and are evaluating a possible IPO of the Company.

NOW, THEREFORE, in consideration of the foregoing, the Parties agree as follows:

1.		Subsection 1.3-5 shall be replaced by the following:
		“SPV: The SPV shall be established under the laws of the Republic of China by the Parties for the sole purpose of buying shares in the Company, administrating and selling these shares to the employees of the Company pursuant to the terms and conditions to be set forth by the Company’s Board of Directors. The SPV shall adopt Articles of Incorporation pursuant to the laws of the Republic of China in the form as attached to this Agreement as Appendix I. The SPV shall be set up by the Parties simultaneously with the establishment of the Company

		and shall be capitalized by the Parties with NT$700 million (equivalent of US$20 million) in equal installments by each Party of NT$350 million (equivalent of US$10 million). The SPV shall then subscribe for 70 million shares of the Company at nominal value of NT$10 per share. Upon affirmative decision of the Parties and subject to the conditions as to be determined by the Board of Directors of the Company and the SPV, the SPV shall later offer the shares in the Company to the Company’s employees, whereby the sales price per share shall be at least NT$15 per share. The exact selling price shall be determined by the Board of the Company and the SPV. Upon completion of this employee participation program, the SPV shall be dissolved and the proceeds from the share sale (equivalent of at least US$30 million) shall be redistributed to the Parties according to their respective shareholding of 50% in the SPV. “
2.		Subsection 1.3-8 shall be deleted.
3.		Subsection 1.3-9 shall be replaced by the following:
		“Before an IPO of the Company, agreement between the Parties shall be necessary to determine the timing and necessity of increases in the capital of the Company. Furthermore, for such agreed capital increases as indicated herein, each Party shall have the right and obligation to subscribe to new shares in the same proportion as its then current ownership of shares. No third party shall subscribe to share capital of the Company unless jointly agreed upon by the Parties or otherwise provided by law. For the avoidance of doubt, this Agreement shall impose no obligation on any Party to provide any additional funding other than what is stipulated herein, whether in the forms of loans, equity or otherwise.”
4.		Subsection 1.4-1 shall be replaced by the following:
		“Within five (5) years after the incorporation of the Company, or until the shares of the Company are listed on Taiwan Stock Exchange, or any stock exchange out of the Republic of China (the “Stock Exchange”), whichever is earlier, neither Party shall, without the prior written consent of the other Party, sell, transfer or otherwise dispose of its shares (except for, (i) transferring all but not part of its shares to an Affiliate, or (ii) transfers of shares to employees under Subsection 1.3-6, each under the terms of this Agreement and in accordance with the provisions of the Articles of Incorporation), or pledge, hypothecate or otherwise use its shares as security, or grant options over its legal and beneficial interest in its shares. Any action of a Party violating this provision shall be void and shall be considered a material breach of this Agreement in accordance with Subsection 7.3 (a).”

5.		The last paragraph of Subsection 1.4-2 shall be replaced by the following:
		“For the purpose of this Subsection 1.4-2, Off-the-Market Sale shall mean the sale of shares of the Company not through the Stock Exchange or not via Depository Receipts.”
6.		Subsection 1.4-9 shall be replaced by the following:
		“Minimum Shareholding
(a)		Notwithstanding anything to the contrary of other provisions set forth in this Article 1, each Party shall own a minimum of 33.5% of the outstanding shares of the Company at any time (the “Minimum Shareholding”); and shall not pledge, hypothecate or otherwise use its shares as security, or grant options over its legal and beneficial interest in these 33.5% of the outstanding shares (“Encumbrance”).
(b)		Any action in violation of this provision shall be considered a material breach of this Agreement according to Subsection 7.3 (a).
(c)		In case the non-breaching Party decides not to terminate this Agreement for material breach according to Subsection 7.3(a), it may choose that each Party’s Output Share shall be adjusted by the following formula: The breaching Party shall be obligated to offer to the non-breaching Party, and the non-breaching Party shall have the right of first refusal to the offer from the breaching Party, a share of the Total Capacity amounting to 1.5[x]% of the Total Capacity of the Company if the breaching Party’s shareholding is [x]% less than 33.5% of the shares of the Company, or if the breaching Party’s shareholding free of any Encumbrance is [x]% less than 33.5% of the shares of the Company. By way of example: If the breaching Party’s shareholding is decreased to 16% of the outstanding shares of the Company, it shall offer to the non-breaching Party 26.25% (1.5[33.5-16])% of the Total Capacity. The terms Output Share and Total Capacity used in this Subsection 1.4-9 shall have the same meaning as defined in the PPCRA and the Parties shall cause the Company to comply with this Subsection 1.4-9.
(d)		Further to the rights of the non-breaching Party to terminate this Agreement pursuant to Section 7.3 (a), or to claim an adjustment of the Output Share pursuant to Subsection 1.4-9 (c), the breaching Party shall on written request of the non-breaching Party:

	–		withdraw one of its appointed directors if the shareholding of the breaching Party drops below 30%;
	–		withdraw two of its appointed directors if the shareholding of the breaching Party drops below 26%;

	–		withdraw three of its appointed directors and its appointed supervisor if the shareholding of the breaching Party drops below 22%;
	–		withdraw four of its appointed directors and its appointed supervisor if the shareholding of the breaching Party drops below 16.75%.”

7.		Subsection 1.4-10 shall be added to the Agreement:
		“1.4-10 Depository Receipts Offering
		Subject to the Minimum Shareholding each Party shall be entitled to dispose of its shareholding in the Company via the offering of depository receipts. If a Party intends to do so, it shall first inform the other Party of the volume of shares to be offered and the anticipated price. The other Party may request within 15 days to participate in such offering, or to buy the first Party’s shares intended to be offered via depository receipts, provided that the Parties can agree on the conditions for such joint offering, or a price for the shares within the 15 days period. In any event and even if there is no agreement within the above 15 days period, the Parties agree to cause their nominees on the board of the Company to support such offerings and to vote affirmatively on any resolution required for such offering. The Parties shall cause the Company to sponsor such offering of depository receipts and to file all necessary applications, in particular with the Securities and Futures Bureau.”
8.		Section 2.2 shall be replaced by the following:
		“2.2 Directors, Supervisors, President and Executive Vice President
