Report of Independent Registered Public Accounting Firm

To the Participants and Administrator of
Pioneer Hi-Bred International, Inc. Savings Plan

In our opinion, the accompanying statements of net assets available for benefits and the related statements of changes in net assets available for benefits present fairly, in all material respects, the net assets available for benefits of Pioneer Hi-Bred International, Inc. Savings Plan (the “Plan”) at December 31, 2007 and 2006, and the changes in net assets available for benefits for the years then ended in conformity with accounting principles generally accepted in the United States of America. These financial statements are the responsibility of the Plan’s management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

Our audits were conducted for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental Schedule of Assets (Held at End of Year) is presented for the purpose of additional analysis and is not a required part of the basic financial statements but is supplementary information required by the Department of Labor’s Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. This supplemental schedule is the responsibility of the Plan’s management. The supplemental schedule has been subjected to the auditing procedures applied in the audits of the basic financial statements and, in our opinion, is fairly stated in all material respects in relation to the basic financial statements taken as a whole.

Notes to Financial Statements

NOTE 1 — DESCRIPTION OF PLAN

The following description of the Pioneer Hi-Bred International, Inc. Savings Plan (“Plan”) provides only general information. Participants should refer to the Plan document for a more complete description of the Plan’s provisions.

General

The Plan is a defined contribution plan subject to the provisions of the Employee Retirement Income Security Act of 1974 (“ERISA”), as amended. The Plan is available to all full-time employees and all temporary employees of Pioneer Hi-Bred International, Inc. (the “Company”), a wholly owned subsidiary of E. I. du Pont de Nemours and Company (“DuPont”), who have completed at least 1,000 hours of service during a consecutive twelve-month period.

The Plan is administered by the Company. Vanguard Fiduciary Trust Company (“VFTC”) is the trustee of the assets of the Plan. As trustee, VFTC has the authority to hold, manage and protect the assets of the Plan in accordance with the provisions of the Plan and the trust agreements.

Contributions

Participants may contribute 1 percent to 100 percent of their eligible earnings, as defined by the Plan. Participants who have attained age 50 before the end of the Plan year are eligible to make catch-up contributions. Participants may also contribute amounts representing distributions from other qualified defined benefit or defined contribution plans. The Company makes a matching contribution of 100 percent of the first 4 percent of each participant’s before-tax contribution. Contributions to the Plan are subject to certain limits imposed by the Internal Revenue Service (“IRS”) and the Plan terms.

Participants direct the investment of their contributions into various investment options offered by the Plan. The Plan offers eight mutual funds, a common/collective trust fund, a DuPont Company Stock fund, and four predefined investment mixes as investment options for participants. The predefined investment mixes represent an investment in five of the investment options in varying percentages based upon the participant’s desired risk/return strategy. The four predefined investment mixes are: (1) Income, (2) Balanced Growth, (3) Growth, and (4) Aggressive Growth.

Participant Accounts

Each participant’s account is credited with the participant’s contribution and allocations of (a) the Company’s contribution and (b) Plan earnings, and charged with an allocation of administrative expenses. Allocations are based on participant earnings or account balances, as defined. The benefit to which a participant is entitled is the benefit that can be provided from the participant’s vested account.

Vesting

Upon entering the Plan, participants are fully vested in their contributions plus earnings thereon. Effective January, 1 2006, any participant who completes an hour of service is immediately vested in their Company match.

Notes to Financial Statements

Participant Loans

Subject to the Plan’s guidelines, participants may borrow from their fund accounts a minimum of $1,000 up to a maximum equal to the lesser of $50,000 (less the participant’s highest outstanding loan balance during the previous twelve months) or 50 percent of their account balance, whichever is less. The loans are secured by the balance in the participant’s account and bear interest at rates that range from 5 percent to 9.25 percent, which are commensurate with local prevailing rates as determined by the Plan administrator. Principal and interest is paid ratably through payroll deductions. A maximum of one loan per participant may be outstanding at any time and loan maturities cannot exceed five years.

Payment of Benefits

An in-service withdrawal of all or a portion of a participant’s account may be made under certain conditions including election by the participant after attaining age 59¹/2. Withdrawals of employee contributions for undue financial hardship are also permitted. Upon termination or retirement a participant who has attained age 55 may elect to take a partial distribution. Upon termination or retirement, prior to age 55, death or disability, a participant may elect to receive a lump-sum distribution equal to the vested value of the participant’s account.

Forfeited Accounts

Upon the participant’s termination of employment, any Company matching contributions and the earnings thereon which are not vested will be forfeited, but will be restored and eligible for additional vesting if the participant again becomes an eligible employee within five years after termination and completes the required years of service. Forfeitures, net of amounts restored, are used to reduce future Company contributions required under the Plan. Forfeitures were not used to offset Company contributions during the years ended December 31, 2007 and 2006. At December 31, 2007 and 2006, forfeited non-vested accounts totaled $55,903 and $45,585, respectively.

Administrative Expenses

Reasonable expenses of administering the Plan, at the election of the Company, may be paid by the Plan. Any remaining expenses will generally be paid by the Company, but may be paid by the Plan. For the years ended December 31, 2007 and 2006, the Plan paid $203,288 and $202,607, respectively, in administrative expenses of the Plan, including recordkeeping related fees. Brokerage fees, transfer taxes, investment fees and other expenses incidental to the purchase and sale of securities and investments are included in the cost of such securities or investments or deducted from the sales proceeds.

NOTE 2 — SUMMARY OF ACCOUNTING POLICIES

Basis of Accounting

The financial statements of the Plan are prepared under the accrual method of accounting.

Pioneer Hi-Bred International, Inc. Savings Plan
Notes to Financial Statements

As described in Financial Accounting Standards Board Staff Position, FSP AAG INV-1, Reporting of Fully Benefit-Responsive Investment Contracts Held by Certain Investment Companies subject to the AICPA Investment Company Audit Guide and Defined Contribution Health and Welfare and Pension Plans (the “FSP”), investment contracts held by a defined contribution plan are required to be reported at fair value. This applies even when the contracts are not held directly by the Plan but are underlying assets in Common Collective Trust (“CCT”) investments held by the Plan. However, contract value is the relevant measurement of net assets available for benefits in a defined contribution plan that holds fully benefit-responsive investment contracts because contract value is the amount participants would receive if they were to initiate permitted transactions under the terms of the Plan. As required by the FSP, the Statement of Net Assets Available for Benefits presents the fair value of the interest in CCT’s relating to fully benefit-responsive investment contracts with an adjustment to contract value. The Statement of Changes in Net Assets Available for Benefits is prepared on a contract value basis.

Use of Estimates

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates that affect the financial statements and accompanying notes. Actual results could differ from those estimates.

Investment Valuation and Income Recognition

The Plan’s investments are stated at fair value. Shares of registered investment companies (“mutual funds”) are valued at the net asset value of shares held by the Plan at year end. Shares of CCT’s are valued at net unit value as determined by the trustee at year end. The Company stock fund is valued at year-end unit closing price (defined as the year-end market price of common stock plus uninvested cash position). Participant loans are valued at their outstanding balances, which approximate fair value.

The Plan holds shares of CCT’s that have investments in fully benefit-responsive investment contracts. For purposes of the Statement of Net Assets Available for Benefits, these CCT’s are stated at fair value. As provided in the FSP, an investment contract is generally required to be reported at fair value, rather than contract value, to the extent it is fully benefit-responsive. The fair value of such investment contracts held by the CCT’s are determined using the market price of the underlying securities and the value of the investment contract.

Purchases and sales of investments are recorded on a trade-date basis. Interest income is recorded on the accrual basis. Dividend income is recorded on the ex-dividend date. Capital gain distributions are included in dividend income.

Payment of Benefits

Benefits are recorded when paid.

Accounting Standards Issued Not Yet Adopted

In September 2006, the Financial Accounting Standards Board (FASB) issued Statement of Financial Accounting Standards (SFAS) No. 157, “Fair Value Measurements,” (SFAS 157) which addresses how companies should measure fair value when required for recognition or disclosure purposes under GAAP. The standard’s provisions will be applied to existing accounting measurements and related disclosures that are based on fair value. SFAS 157 does not require any new fair value measurements. The standard applies a common definition of fair value to be used throughout GAAP, with emphasis on fair value as a “market-based” measurement versus an entity-specific measurement and establishes a hierarchy of fair value measurement methods. The disclosure requirements are expanded to include the extent to which companies use fair value measurements, the methods and assumptions used to measure fair value and the effect of fair value measurements on earnings. SFAS 157 is effective for fiscal years beginning after November 15, 2007. The new standard’s provisions applicable to the Plan will be applied to the Plan’s financial statements prospectively for the period beginning January 1, 2008. The Plan administrator expects that the adoption of SFAS 157 will not have a material effect on the Plan’s net assets available for benefits or changes in net assets available for benefits.

NOTE 9 — RISKS AND UNCERTAINTIES

The Plan invests in various investment securities. Investment securities are exposed to various risks such as interest rate, market and credit risks. Due to the level of risk associated with certain investment securities, it is at least reasonably possible that changes in the values of investment securities will occur in the near term and that such changes could materially affect participants’ account balances and the amounts reported in the statement of net assets available for benefits.
