(c)           All costs and expenses incurred in administering the Plan shall be paid by the Company.  The Board or the Plan Administrator may request advice for assistance or employ such other persons as are necessary for proper administration of the Plan.

Section 5.               Eligibility and Participation.

(a)           Any person who qualifies or will qualify as an Eligible Employee on the Date of Participation with respect to a Participation Period may elect to participate in the Plan for such Participation Period.  An Eligible Employee may elect to participate by submitting the prescribed enrollment form.  The enrollment form shall be filed with the Stock Administrator no later than the filing deadline imposed and communicated to Eligible Employees with respect to the Participation Period for which such enrollment form is intended to be effective by the Stock Administrator, and if none is so imposed and/or communicated, then no later than five (5) days before the Participation Period for which such enrollment form is intended to be effective.  The Eligible Employee shall designate on the enrollment form the percentage of his or her Compensation which he or she elects to have withheld for the purchase of Stock, which may be any whole percentage from 1 to 15% of the Participant’s Compensation.

(b)           By enrolling in the Plan, a Participant shall be deemed to have been granted an option on his or her Date of Participation to purchase the maximum number of whole shares of Stock which can be purchased with the amount of the Participant’s Compensation which is withheld during each Purchase Period within the Participation Period for which the Participation is enrolled.  However, with respect to any Purchase Period, no Participant shall be eligible to purchase more than five thousand (5,000) shares of Stock provided that such amount shall not result in the limitations set forth in Section 13 being exceeded.  Notwithstanding the foregoing, effective as of October 1, 2002, the Plan Administrator, or a committee appointed by the Plan Administrator, which committee may be comprised solely of employees of the Company, shall have the right to amend the limit set forth in this Section 5(b) with respect to Purchase Periods commencing after the date of such amendment; provided, however, that in no event shall the limit exceed five thousand (5,000) shares of Stock per Purchase Period or the limitations set forth in Section 13.

(c)           Once enrolled, a Participant will continue to participate in the Plan for each succeeding Purchase Period and each succeeding Participation Period until he or she terminates participation or ceases to qualify as an Eligible Employee.  A Participant who

4

withdraws from the Plan in accordance with Section 9 may again become a Participant in a subsequent Participation Period, if he or she then is an Eligible Employee, by following the procedure described in Section 5(a).

(d)           If the Fair Market Value of a share of Stock on the Date of Participation for the current Participation Period in which a Participant is enrolled is higher than the Fair Market Value of a share of Stock on the first day of any subsequent Participation Period, the Company will (after the Purchase Period), terminate the current Participation Period, and the Participant’s Date of Participation shall be the first day of such subsequent Participation Period until changed in accordance with the terms of this Plan.

Section 6.               Purchase Price.

The Purchase Price for each share of Stock shall be the lesser of (i) eighty–five percent (85%) of the Fair Market Value of such share on the Date of Participation or (ii) eighty–five percent (85%) of the Fair Market Value of such share on the Date of Exercise, for an applicable Participation Period.

Section 7.               Employee Contributions.

A Participant may purchase shares of Stock solely by means of payroll deductions.  Payroll deductions, as designated by the Participant pursuant to Section 5(a), shall commence with the first paycheck issued during the Purchase Period and shall be deducted from each subsequent paycheck throughout the Purchase Period; provided, however, that, with respect to a Participant, the Company shall be entitled to discontinue payroll deductions for such Participant during a Purchase Period to the extent that the Company determines that the payroll deductions for such Participant during such Purchase Period will cause the Participant to exceed the limitations set forth in Sections 5 or 13; provided, further, that the Company will recommence payroll deductions for such Participant on the first day of the next Purchase Period to the extent the limitation set forth in Section 13 has not been exceeded.  If a Participant desires to decrease the rate of payroll withholding during the Purchase Period, he or she may do so one time during a Purchase Period by submitting the prescribed percentage change form with the Stock Administrator.  Such decrease will be effective no later than the first day of the second period, which begins following the receipt of the new percentage change form.  If a Participant desires to increase or decrease the rate of payroll withholding, he or she may do so effective for the next Purchase Period by submitting a new percentage change form with the Stock Administrator on or before the date imposed and communicated to Eligible Employees by the Stock Administrator, and if none is so imposed and/or communicated, then no later than five (5) days before the Purchase Period for which such change is to be effective.

Section 8.               Plan Accounts; Purchase of Shares.

(a)           The Company will maintain a Plan Account on its books in the name of each Participant.  At the close of each pay period, the amount deducted from the Participant’s Compensation will be credited to the Participant’s Plan Account.

5

(b)           As of each Date of Exercise, the amount then in the Participant’s Plan Account will be divided by the Purchase Price, and the number of whole shares which results (subject to the limitations described in Sections 5(b), 8(c) and 13) shall be purchased from the Company with the funds in the Participant’s Plan Account.  The number of shares of Stock so purchased shall be delivered to a brokerage account designated by the Plan Administrator and kept in such account pursuant to the enrollment form (which shall be uniform) between each Participant and the Company and subject to the conditions described therein (which may include, without limitation, restrictions on transferability of the shares of Stock so purchased).

(c)           In the event that the aggregate number of shares which all Participants elect to purchase during a Purchase Period shall exceed the number of shares remaining available for issuance under the Plan, then the number of shares to which each Participant shall become entitled shall be determined by multiplying the number of shares available for issuance by a fraction the numerator of which is the sum of the number of shares the Participant has elected to purchase pursuant to Section 5, and the denominator of which is the sum of the number of shares which all employees have elected to purchase pursuant to Section 5.  Any cash amount remaining in the Participant’s Plan Account under these circumstances shall be refunded to the Participant.

(d)           Any amount remaining in the Participant’s Plan Account caused by a surplus due to fractional shares after deducting the amount of the Purchase Price for the number of whole shares issued to the Participant shall be carried over in the Participant’s Plan Account for the succeeding Purchase Period, without interest.  Any amount remaining in the Participant’s Plan Account caused by anything other than a surplus due to fractional shares shall be refunded to the Participant in cash, without interest.

(e)           As soon as practicable following the end of each Purchase Period, the Company shall deliver to each Participant a Plan Account statement setting forth the amount of payroll deductions, the Purchase Price, the number of shares purchased and the remaining cash balance, if any.

Section 9.               Withdrawal From the Plan.

A Participant may elect to withdraw from participation under the Plan at any time up to the last day of a Purchase Period by submitting the prescribed withdrawal form with the Stock Administrator.  As soon as practicable after a withdrawal, payroll deductions shall cease and all amounts credited to the Participant’s Plan Account will be refunded in cash, without interest.  A Participant who has withdrawn from the Plan shall not be a Participant in future Participation Periods, unless he or she again enrolls in accordance with the provisions of Section 5.

Section 10.             Effect of Termination of Employment or Death.

(a)           Termination of employment as an Eligible Employee for any reason, including death, shall be treated as an automatic withdrawal from the Plan under Section 9.  A transfer from one Participating Company to another shall not be treated as a termination of employment.

6

(b)           A Participant may file a written designation of a beneficiary who is to receive any shares and cash, if any, from the Participant’s Account under the Plan in the event of such Participant’s death subsequent to the purchase of shares but prior to delivery to him or her of such shares and cash.  In addition, a Participant may file a written designation of a beneficiary who is to receive any cash from the Participant’s Account under the Plan in the event of such Participant’s death prior to the last day of a Purchase Period.  Designation of a beneficiary is located on page 2 of the prescribed enrollment form.

(c)           Such designation of beneficiary may be changed by the Participant at any time by submitting the prescribed designation of beneficiary change form with the Stock Administrator.  In the event of the death of a Participant in the absence of a valid designation of a beneficiary who is living at the time of such Participant’s death, the Company shall deliver such shares and/or cash in accordance with the Participant’s designation of beneficiaries under the Integrated Device Technology, Inc. 401(k) Savings Plan; or, in the absence of such designation, to the executor or administrator of the estate of the Participant; or if no such executor or administrator has been appointed (to the knowledge of the Company), the Company, in its discretion, may deliver such shares and/or cash to the spouse or to any one or more dependents or relatives of the Participant; or if no spouse, dependent or relative is known to the Company, then to such other person as the Company may designate.

Section 11.             Rights Not Transferable.

The rights or interests of any Participant in the Plan, or in any Stock or moneys to which he or she may be entitled under the Plan, shall not be transferable by voluntary or involuntary assignment or by operation of law, or by any other manner other than as permitted by the Code or by will or the laws of descent and distribution.  If a Participant in any manner attempts to transfer, assign or otherwise encumber his or her rights or interest under the Plan, other than as permitted by the Code or by will or the laws of descent and distribution, such act shall be treated as an automatic withdrawal under Section 9.

Section 12.             Recapitalization, Etc.

(a)           The aggregate number of shares of Stock offered under the Plan, the number and price of shares which any Participant has elected to purchase pursuant to Section 5 and the maximum number of shares which a Participant may elect to purchase under the Plan in any Purchase Period shall be proportionately adjusted for any increase or decrease in the number of issued shares of Stock resulting from a subdivision or consolidation of shares or any other capital adjustment, the payment of a stock dividend, or other increase or decrease in such shares affected without receipt of consideration by the Company.

(b)           In the event of a dissolution or liquidation of the Company, or a merger or consolidation to which the Company is a constituent corporation, this Plan shall terminate, unless the plan of merger, consolidation or reorganization provides otherwise, and all amounts which each Participant has paid towards the Purchase Price of Stock hereunder shall be refunded, without interest.

7

(c)           The Plan shall in no event be construed to restrict in any way the Company’s right to undertake a dissolution, liquidation, merger, consolidation or other reorganization.

Section 13.             Limitation on Stock Ownership.

Notwithstanding any provision herein to the contrary, no Participant shall be permitted to elect to participate in the Plan (i) if such Participant, immediately after his or her election to participate, would own stock possessing five percent (5%) or more of the total combined voting power or value of all classes of stock of the Company or any parent or Subsidiary of the Company, or (ii) if under the terms of the Plan the rights of the Employee to purchase Stock under this Plan and all other qualified employee stock purchase plans of the Company or its Subsidiaries would accrue at a rate which exceeds twenty–five thousand dollars ($25,000) of the Fair Market Value of such Stock (determined at the time such right is granted) for each calendar year for which such right is outstanding at any time.  Nothing in this Section shall cause a Participant’s Date of Participation to be other than as would be determined pursuant to the Plan without regard to the limitations set forth in this Section.  For purposes of this Section, ownership of stock shall be determined by the attribution rules of Section 425(d) of the Code, and Participants shall be considered to own any stock which they have a right to purchase under this or any other stock plan.

Section 14.             No Rights as an Employee.

Nothing in the Plan shall be construed to give any person the right to remain in the employ of a Participating Company.  Each Participating Company reserves the right to terminate the employment of any person at any time and for any reason.

Section 15.             Rights as a Stockholder.

A Participant shall have no rights as a stockholder with respect to any shares he or she may have a right to purchase under the Plan until the date of issuance to the brokerage account designated by the Plan Administrator the shares of Stock issued pursuant to the Plan.

Section 16.             Use of Funds.

All payroll deductions received or held by the Company under the Plan may be used by the Company for any corporate purpose, and the Company shall not be obligated to segregate such payroll deductions in separate accounts.

Section 17.             Amendment or Termination of the Plan.

Except as otherwise provided herein, the Board of Directors shall have the right to amend, modify or terminate the Plan at any time without notice.  An amendment of the Plan shall be subject to shareholder approval only to the extent required by applicable laws, regulations or rules.

The Plan shall be governed by, and construed and interpreted in accordance with, the laws of the State of Delaware.
