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 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. We were not engaged to perform an audit of the Plan's internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Plan's internal control over financial reporting. Accordingly we express no such opinion. An audit also 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. In our opinion, the financial statements referred to above present fairly, in all material respects, the net assets available for benefits of the Plan at December 31, 2005 and 2004, and the changes in its net assets available for benefits for the years then ended, in conformity with U.S. generally accepted accounting principles. Our audits were performed for the purpose of forming an opinion on the financial statements taken as a whole. The accompanying supplemental schedule of assets (held at end of year) as of December 31, 2005, is presented for purposes of additional analysis and is not a required part of the 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. The supplemental schedule is the responsibility of the Plan's management. The supplemental schedule has been subjected to the auditing procedures applied in our audits of the financial statements and, in our opinion, is fairly stated in all material respects in relation to the financial statements taken as a whole.

The plan is subject to the provisions of the Employee Retirement Income Security Act of 1974 (ERISA). On April 1, 2004, Prudential Financial, Inc. (Prudential) completed an acquisition of the retirement business of CIGNA Corporation. As a result of this transaction, the Plan's recordkeeper and custodian functions are now being performed by businesses controlled by or affiliated with Prudential. Participants may contribute up to the lesser of $14,000 in 2005 and $13,000 in 2004 or their annual compensation less FICA taxes. All participants, except those in collective bargaining units, are eligible to receive matching Rogers Corporation (the "Company") contributions. The Company may contribute any factor from 0% to 50% of each participant's contribution, as determined by the Board of Directors. The Company contributed 50% of the first 5% of each participant's annual compensation in 2005 and 2004. All contributions are participant directed. Participants may borrow from their fund accounts a minimum of $1,000 and a maximum equal to the lesser of $50,000 subject to certain IRS restrictions, or 50 percent of their vested account balance. Loan terms range from one month to five years or up to fifteen years for the purchase of a primary residence. The loans are secured by the balance in the participant's account and bear interest at a rate commensurate with local prevailing rates as determined periodically by the Plan administrator. Principal and interest are paid ratably through payroll deductions. Each participant's account reflects the individual's pretax contribution, the Company's contribution (if applicable), an allocation of Plan earnings, and rollovers (if applicable). Total earnings by fund are allocated daily to individual accounts. Participants are 100% vested in their contributions and to the extent a participant is not eligible for retirement he or she is vested as to the Company's contributions at 25% after two years of continuous service, increased by 25% for each additional year of continuous service up to 100%. Upon early retirement, normal retirement, total disability, as defined by the Plan, death, or ceasing to be an Employee of the Company and a participant in the Plan on or after December 1, 2002 as a result of becoming an employee of a joint venture in which the Company has at least 30% ownership, a participant is 100% vested as to the Company's contributions. Any nonvested participant who is terminated and not re-employed with the Company within five years of termination forfeits his or her interest in the nonvested portion of the Company's contributions. If re-employed within five years, the participant will recover his or her rights in this nonvested portion. Forfeitures used to offset Company contributions and administrative expenses were $72,097 and $69,218 during 2005 and 2004, respectively. The forfeiture balance at December 31, 2005 and 2004 was $15,191 and $7,056, respectively. A participant's tax-deferred contributions cannot be withdrawn prior to age 59-1/2 except for an immediate financial hardship, as defined by the Plan. Company contributions can be drawn upon after five years in the Plan and a participant can withdraw funds for any reason upon reaching age 59-1/2. Upon early retirement, normal retirement, total disability, as defined by the Plan, death, or any other termination of employment, a participant may receive the value of the vested portion of his or her total account offset by any outstanding Plan loans. 4 NOTES TO FINANCIAL STATEMENTS ROGERS EMPLOYEE SAVINGS AND INVESTMENT PLAN (continued) NOTE A - DESCRIPTION OF THE PLAN (continued) Effective January 1, 2004, the Durel Corporation Voluntary Investment Plan was merged into the Rogers Employee Savings and Investment Plan. All participants employed by Durel immediately prior to Durel's becoming a wholly owned subsidiary of Rogers Corporation in 2003, will be credited with their entire period of service with Durel, and any predecessor entity in interest thereof, for purposes of determining the employee's vesting service. Plan Termination Although it has not expressed any intent to do so, the Company has the right under the Plan to discontinue its contributions at any time and to terminate the Plan subject to the provisions of ERISA. In the event of Plan termination, participants would become 100% vested in their accounts. NOTE B - SIGNIFICANT ACCOUNTING POLICIES Basis of Accounting The accounts of the Plan are reported on the accrual basis. Valuation of Investments Securities traded on a national securities exchange are valued at the last reported sales price on the last business day of the plan year. Investments in pooled separate accounts are stated at fair value based on the year end market value of each unit held, which is based upon the market value of the underlying assets of the funds less investment management fees and asset charges. The investment in Prudential's Guaranteed Income Fund is valued at contract value as estimated by Prudential, which approximates market. Contract value represents contributions made under the contract plus interest at the contract rate, less funds used to pay termination benefits, in-service withdrawals, and to pay for the insurance company's administrative expenses. The interest rate for Prudential's guaranteed long-term fund is determined twice a year and is guaranteed not to change for six months. The average interest rate was 3.7% for 2005 and 3.0% for 2004. The average crediting interest rate was 3.50% in both 2005 and 2004. Use of Estimates The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and changes therein, and disclosure of contingent assets and liabilities. Actual results could differ from those estimates. Administrative Expenses The majority of the costs and expenses incurred in connection with the operation of the Plan have been borne by Rogers Corporation. 5 NOTES TO FINANCIAL STATEMENTS ROGERS EMPLOYEE SAVINGS AND INVESTMENT PLAN (continued) NOTE C - INVESTMENTS The following presents investments that represent five percent or more of the Plan's net assets.

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 statements of net assets available for benefits. NOTE F - INCOME TAX STATUS The Internal Revenue Service has determined and informed the Company by a letter dated October 16, 2002, that the Plan qualifies under Section 401(a) of the Internal Revenue Code (IRC) and is, therefore, not subject to tax under present income tax law. Subsequent to this issuance of the determination letter, the Plan was amended. Once qualified, the Plan, as amended, is required to operate in conformity with the IRC to maintain its qualification. The RESIP Committee is not aware of any course of action or series of events that have occurred that might adversely affect the Plan's qualified status. 6 SCHEDULE H, LINE 4i: SCHEDULE OF ASSETS (HELD AT END OF YEAR) EIN NO: 06-0513860 PLAN NO: 006 ROGERS EMPLOYEE SAVINGS AND INVESTMENT PLAN December 31, 2005 Description of Investment - Including Maturity Date Identity of Issue Rate of Interest, Current or Borrower Par or Maturity Value Value -------------------------------------------------------------------------------------------------------------------- Equity Funds Prudential Pooled Separate Accounts:* Small Cap Growth/TimesSquare 102,553.7732 units of participation $ 2,142,283 Fidelity Equity-Income II Account 118,169.1521 units of participation 6,827,813 Dryden S&P 500 Index Account 49,454.2734 units of participation 3,453,477 Large Cap Growth/Goldman Sachs 172,105.5732 units of participation 1,862,684 Mid Cap Value/Wellington Mgmt 191,139.4605 units of participation 3,506,792 Small Cap Value/TS & W 159,629.4030 units of participation 2,664,741 Mid Cap Growth/Artisan Partners 174,852.3572 units of participation 1,930,512 Lifetime 20 Fund 77,043.3094 units of participation 1,154,828 Lifetime 30 Fund 37,418.7604 units of participation 562,435 Lifetime 40 Fund 132,525.2869 units of participation 1,958,075 Lifetime 50 Fund 48,077.9638 units of participation 712,808 Lifetime 60 Fund 12,310.6888 units of participation 182,537 Oakmark Equity & Income Class 1 43,962.5840 units of participation 1,175,395 International Equity/Julius Baer 251,414.3776 units of participation 4,827,505 LN AP Fund 0 units of participation 69 ----------------- 32,961,954 Fixed Income Funds Guaranteed Income Fund* 950,321.8708 units of participation 25,420,357 Corp Bond/BSAM Fund 2,815.5703 units of participation 43,542 Rogers Stock Fund Rogers Corporation* - Common Stock 382,595.3086 shares 14,990,084 Loan Fund Participant loans * Participant loans, interest from 4.50% 1,446,241 to 10.5% ----------------- $ 74,862,178 ================= * Indicates party-in-interest to the Plan. 7
