                             ---------------------
 
                 INFORMATION CONCERNING SOLICITATION AND VOTING
 
GENERAL
 
    A proxy in the accompanying form is solicited by the Board of Directors of
Lattice Semiconductor Corporation (the "Company") for use at the 1997 Annual
Meeting of Stockholders (the "Annual Meeting") to be held at the Portland Hilton
Hotel, 921 SW 6th Ave, Portland, OR 97204, on Monday, August 11, 1997 at 1:00
p.m., Pacific Time, or at any adjournment thereof. The proxy is solicited for
the purposes set forth herein and in the accompanying Notice of Annual Meeting
of Stockholders. The mailing address of the Company's principal executive office
is 5555 NE Moore Court, Hillsboro, Oregon 97124-6421, and the telephone number
at that address is (503) 681-0118.
 
    These proxy solicitation materials were mailed on or about July 1, 1997,
together with the Company's 1997 Annual Report to Stockholders, to all
stockholders entitled to vote at the meeting.
 
    The power of the proxy holders will be suspended if the stockholder of
record executing the proxy is present at the meeting and elects to vote in
person. Any proxy may be revoked prior to its exercise upon written notice to
the Secretary of the Company or upon delivery to the Secretary of the Company of
a duly executed proxy bearing a later date. The shares represented by each
valid, unrevoked proxy will be voted in accordance with the instructions
specified in the proxy, if given. If a signed proxy is returned without
instructions, it will be voted for the nominees for director, for the approval
of the proposals presented, and in accordance with the recommendations of the
Board of Directors on any other business which may properly come before the
meeting or matters incident to the conduct of the meeting.
 
    The Company's outstanding voting securities at the close of business on June
12, 1997 consisted of 23,066,825 shares of Common Stock, $.01 par value per
share (the "Common Stock"), each of which is entitled to one vote on all matters
to be presented at the meeting. Only stockholders of record at the close of
business on June 12, 1997 (the "record date") are entitled to notice of and to
vote at the meeting or any adjournment thereof. The Common Stock does not have
cumulative voting rights.
 
    The required quorum for the transaction of business at the Annual Meeting is
a majority of shares of Common Stock outstanding on the Record Date. Shares that
are voted "FOR", "AGAINST", "ABSTAIN" or "WITHHELD" from a matter are treated as
being present at the meeting for purposes of establishing a quorum and are also
treated as votes eligible to be cast by the Common Stock present in person or
represented by proxy at the Annual Meeting and "entitled to vote on the subject
matter" (the "Votes Cast") with respect to such matter.
 
    Abstentions and votes "withheld" will be counted for purposes of determining
both the presence or absence of a quorum for the transaction of business and the
total number of Votes Cast with respect to a particular matter. Broker non-votes
with respect to proposals set forth in this Proxy Statement will be counted only
for purposes of determining the presence or absence of a quorum and will not be
considered "Votes Cast", and will not affect the determination as to whether the
requisite majority of Votes Cast has been obtained with respect to a particular
matter.

                       PROPOSAL 1: ELECTION OF DIRECTORS
 
DIRECTORS
 
    Pursuant to the Company's Certificate of Incorporation as amended and
restated (the "Certificate"), the Board of Directors is divided into three
classes. The directors are elected to serve staggered three-year terms, such
that the term of one class of directors expires each year. Each class consists
of two directors. Two Class II directors are to be elected at the Annual Meeting
for a three-year term ending in 2000. The proxy holders intend to vote the
proxies received by them for Mr. Hauer and Mr. Strain, who have been nominated
to the Board of Directors. If the nominees for director become unavailable for
election for any reason, pursuant to the proxy the proxy holders will have
discretionary authority to vote for suitable substitutes. The Company is not
aware of any reason that Mr. Hauer or Mr. Strain will be unable or will decline
to serve as a director. The terms of office of the persons elected as director
will continue until their terms expire in 2000 or until successors have been
elected and qualified.
 
    The following table briefly describes the Company's nominees for director
and the directors whose terms will continue. Except as otherwise noted, each has
held his principal occupation for at least five years. There are no family
relationships among any directors or officers of the Company.

REQUIRED VOTE The two nominees receiving the highest number of affirmative votes of the Votes Cast at the Annual Meeting on this matter shall be elected as the Class II directors. See "Information Concerning Solicitation and Voting--General". THE BOARD OF DIRECTORS RECOMMENDS THAT THE STOCKHOLDERS VOTE "FOR" DANIEL S. HAUER AND DOUGLAS C. STRAIN AS THE CLASS II DIRECTORS OF THE COMPANY. BOARD MEETINGS AND COMMITTEES In fiscal 1997, the Company's Board of Directors held four regularly scheduled meetings. No member of the Board of Directors attended fewer than 75% of the total number of board and committee meetings of the Board of Directors held during fiscal 1997. The Board of Directors currently has three standing committees: the Compensation Committee, the Audit Committee and the Nominating Committee. The Compensation Committee makes recommendations to the Board of Directors concerning the salaries and other compensation paid to the executive officers, the granting of employee stock options and other compensation-related issues. Mr. Strain and Mr. Sonsini were the compensation committee members through May 1996, when Mr. Sonsini resigned and was replaced by Mr. Merlo. The Compensation Committee met twice in fiscal 1997. The Audit Committee recommends engagement of the Company's independent accountants and is primarily responsible for reviewing and approving the scope of the audit and other services performed by the Company's independent accountants and for reviewing and evaluating the Company's accounting principles and its systems of internal accounting controls. The Audit Committee meets with management and the Company's independent accountants, who have access to the Audit Committee with and without the presence of management representatives. During fiscal 1997, the Audit Committee was composed of Mr. Merlo and Mr. Hauer and met twice. A Nominating Committee comprising Mr. Sonsini and Mr. Tsui exists to identify persons for future nomination for election to the Board of Directors. Two meetings were held in fiscal 1997 by the Nominating Committee. Stockholders who wish to submit names to the Nominating Committee for consideration should do so in writing addressed to the Nominating Committee, c/o Corporate Secretary, Lattice Semiconductor Corporation, 5555 NE Moore Court, Hillsboro, Oregon 97124-6421. DIRECTORS' COMPENSATION Directors who are employees of the Company (currently only Mr. Tsui) receive no additional or special remuneration for serving as directors. Each non-employee director receives an annual retainer of $12,000 plus $1,500 for each board meeting attended and $750 for each committee meeting attended. Non-employee directors also receive options to purchase shares of the Company's Common Stock. Prior to May 1993, these options were issued under the Company's Outside Directors Stock Option Plan (the "1990 Directors Plan"). In August 1993, the stockholders approved the 1993 Outside Directors Stock Option Plan (the "1993 Directors Plan") which replaced the 1990 Directors Plan. The 1993 Directors Plan 3 provides for automatic grants of stock options to non-employee directors. Under this plan, each outside director received a grant of 18,000 shares in August 1993. A new director receives a grant for 18,000 shares on the date he is appointed by the Board of Directors. In addition, each outside director will receive a grant of 18,000 shares on the date any previously granted option becomes fully vested. These shares generally vest quarterly over a four-year period. TRANSACTIONS WITH MANAGEMENT Mr. Hauer, a director of the Company, is the Chairman of S-MOS Systems, Inc. ("S-MOS"). The Company has a manufacturing agreement with S-MOS for the production and delivery of silicon wafers. In July 1994, the Company entered into advance payment and research and development agreements with Seiko Epson Corporation and its affiliate S-MOS. Pursuant to the terms of these agreements, the Company made payments of $44 million to Seiko Epson, in approximately even quarterly amounts from July 1994 to March 1995. A second advance payment agreement between the Company and Seiko Epson Corporation and its affiliate S-MOS was entered into in March 1997. Total payments of approximately $90 million (with an option for an additional $60 million) will be made by fiscal 1999. Repayment for the advance payment portions of these agreements will be made in the form of semiconductor wafers over a multi-year period. In fiscal 1997, approximately $18 million of wafers were delivered to the Company in connection with these advance payment agreements. Additionally, in fiscal 1997, cash wafer purchases by the Company from S-MOS totaled $22.8 million. Mr. Sonsini, a director of the Company, is Chairman of the Executive Committee of Wilson Sonsini Goodrich & Rosati, Professional Corporation, a law firm based in Palo Alto, California. This firm serves as the Company's primary outside legal counsel. EMPLOYMENT AGREEMENTS In September 1988, the Company entered into an employment letter with Mr. Tsui pursuant to which Mr. Tsui serves as President and Chief Executive Officer of the Company. In addition to providing for an annual base salary and bonus arrangements, the letter provides that in the event of a change in control of the Company as described in the letter, then any unvested options to purchase common stock of the Company held by Mr. Tsui shall become fully vested. Additionally, in the event Mr. Tsui is involuntarily terminated other than for cause, the Company will continue to pay his salary for up to six months, or until Mr. Tsui begins employment elsewhere, whichever occurs sooner, and options vesting during that period are exercisable. COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION The members of the Compensation Committee through May of 1996 were Mr. Strain and Mr. Sonsini. During the May 13, 1996 Board Meeting, Mr. Sonsini resigned from the Compensation Committee and was replaced by Mr. Merlo. Mr. Sonsini is Chairman of the Executive Committee of the law firm of Wilson Sonsini Goodrich & Rosati, Professional Corporation, primary outside legal counsel to the Company. REPORT OF THE COMPENSATION COMMITTEE The Compensation Committee sets, reviews and administers the executive compensation program of the Company and is comprised of the individuals noted below, both of whom are non-employee directors of the Company. The role of the Compensation Committee is to establish and approve salaries and other compensation paid to the executive officers of the Company and to administer the Company's stock option plan, in which capacity the Compensation Committee reviews and approves stock option grants to all employees. 4 COMPENSATION PHILOSOPHY. Lattice's compensation philosophy is that cash compensation should be directly linked to the short-term performance of the Company and that longer-term incentives, such as stock options, should be aligned with the objective of enhancing stockholder value over the long term. The use of stock options clearly links the interests of the officers and employees of the Company to the interests of the stockholders. In addition, the Compensation Committee believes that the total compensation package must be competitive with other companies in the industry to ensure that the Company can continue to attract, retain and motivate key employees who are critical to the long-term success of the Company. COMPONENTS OF EXECUTIVE COMPENSATION. The principal components of executive compensation are base salary, bonuses under the Executive Incentive Plan, participation in the Company-wide Profit Sharing Plan and stock options. Base salary is set based on competitive factors and the historic salary structure for various levels of responsibility within the Company. The Compensation Committee periodically conducts surveys of companies in the industry in order to determine whether the Company's executive base salaries are in a competitive range. Generally, salaries are set at the middle to high end of the range. In addition, the Company relies on variable compensation in order to emphasize the importance of performance. As a result, in the fiscal year ended March 29, 1997, which was a profitable year for the Company, the salaries of the named executive officers (as subsequently defined) comprised only 28% to 41% of their total cash compensation. The Executive Incentive Plan is a bonus plan that is linked directly to the profitability of the Company. This plan in particular emphasizes the Compensation Committee's belief that, when the Company is successful, the executives should be highly compensated, but that, conversely, if the Company is not successful and is not profitable, no bonuses should be paid absent extraordinary circumstances. Each individual executive officer's portion of the total bonus pool is determined by a formula that is based on the executive's base salary and his or her contribution to the Company. With respect to the Chief Executive Officer the formula is based on his salary and the performance of the Company, and the bonus derived from such formula is paid in a combination of stock and cash, pursuant to the 1996 Stock Incentive Plan as approved by the stockholders. With respect to other executives, a cash bonus is based both on the formula and on individual performance relative to key objectives as determined by the Chief Executive Officer. In addition to the Executive Incentive Plan, the Company has a Profit Sharing Plan under which a specified percentage of operating profit is set aside and distributed equally among all employees, including executives. The principal equity component of executive compensation is the stock option program. Stock options are generally granted when an executive joins the Company and on an annual basis thereafter under a replenishment program. Options are occasionally granted for promotions or other special achievements. The initial option granted to the executive vests over a period of four years. The purpose of the annual replenishment option grant program is to ensure that the executive always has options that vest in increments over the following four-year period. This provides a method of retention and motivation for the senior level executives of the Company and also aligns senior management's objectives with long-term stock price appreciation. In addition to the stock option program, executives are eligible to participate in a payroll deduction employee stock purchase plan pursuant to which stock may be purchased at 85% of the fair market value at the beginning or end of each offering period (up to a maximum of $25,000 worth of stock per calendar year or 10% of salary, whichever is less). Other elements of executive compensation are participation in a Company-wide life insurance program as well as a supplemental life insurance program, long-term disability insurance, Company-wide medical benefits, the ability to defer compensation pursuant to a 401(k) plan and a supplemental deferred compensation plan. Discretionary Company contributions to the 401(k) plan of up to 5% of eligible base pay were made in fiscal 1997. 5 The 1996 Stock Incentive Plan was approved by the stockholders at the 1996 Annual Meeting. This Plan allows the Company to grant certain stock-related benefits and to utilize additional tax deductions which may be available under Section 162(m) of the Internal Revenue Code of 1986. Section 162(m) limits to $1 million the deductibility of annual compensation paid by a public corporation to the chief executive officer and the next four most highly compensated executive officers unless such compensation is performance-based within the meaning of Section 162(m) and the regulations thereunder.

(12) Includes 14,750 shares issuable upon exercise of options. (13) Includes 1,211,375 shares issuable upon exercise of options. SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE Section 16(a) of the Securities Exchange Act of 1934, as amended, requires the Company's officers and directors, and persons who own more than 10% of a registered class of the Company's equity securities, to file reports of ownership on Form 3 and changes in ownership on Form 4 or Form 5 with the Securities and Exchange Commission ("SEC"). Such officers, directors and 10% stockholders are also required by SEC rules to furnish the Company with copies of all Section 16(a) forms they file. Based solely on its review of the copies of such forms received by it, or written representations from certain reporting persons, the Company believes that, during the fiscal year ended March 29, 1997, all Section 16(a) filing requirements applicable to its officers, directors and 10% stockholders were complied with, with two exceptions. A trust, of which Harry A. Merlo, a Director, is a trustee and disclaims beneficial ownership, inadvertently did not file record of a sale of 10,000 shares by the appropriate Form 4 filing date. The Form 4 was filed within two months of the sale. 13,904 shares of stock granted to Cyrus Y. Tsui in the form of a bonus, pursuant to the 1996 Stock Incentive Plan as approved by stockholders, was inadvertently not reported by the appropriate Form 5 filing date. The Form 5 was filed within 30 days of the required date. PROPOSAL 2: APPROVAL OF AMENDMENT TO EMPLOYEE STOCK PURCHASE PLAN The Employee Stock Purchase Plan (the "Purchase Plan") was adopted by the Board of Directors and approved by the stockholders in 1990. The stockholders approved, in August 1993, an increase of 225,000 shares to the original number of shares reserved for the Purchase Plan. In May 1997, the Board of Directors amended the Purchase Plan, subject to stockholder approval, to increase the shares reserved for issuance from 450,000 shares to 700,000 shares. The Board believes that increasing the number of shares available under the Purchase Plan will enable the Company to continue its policy of encouraging employee equity participation in the Company by enabling employees to purchase the Company's Common Stock at a discount from the market price through voluntary payroll deductions. Employee participation in the Purchase Plan has been broadly-based. Approximately 66% of the Company's eligible employees participated in this plan during the purchase period ending December 31, 1996. The Board believes that the increased opportunity for employee equity participation will promote the attraction, retention and motivation of employees. PURCHASE PLAN ACTIVITY Since the Purchase Plan's inception in 1990, and as of June 12, 1997 (without taking into account the proposed amendment to the Purchase Plan), the Company had issued and sold an aggregate of 392,191 shares of Common Stock pursuant to the Purchase Plan and 57,809 shares of Common Stock were 12 available for future issuance under the Purchase Plan. Participation in the Purchase Plan is voluntary and is dependent on each eligible employee's election to participate and his or her determination as to the level of payroll deductions. Accordingly, future purchases under the Purchase Plan are not determinable. The following table sets forth certain information regarding shares purchased under the Purchase Plan during the Company's last fiscal year by each of the named executive officers, all current executive officers as a group and all non-executive officer employees as a group:

- ------------------------ (1) Represents the market value of the shares on the date of purchase. The purchase price paid by each participant in the Purchase Plan is at least 15% below the market value. See "Summary of Purchase Plan--Right to Purchase Shares". SUMMARY OF THE PURCHASE PLAN The purpose of the Purchase Plan is to provide a convenient and practical means for employees of the Company and its participating subsidiaries to purchase the Company's Common Stock and a method by which the Company may assist and encourage its employees to become stockholders. The Purchase Plan is intended to be a permanent program but the Board of Directors may terminate the Purchase Plan at any time. ELIGIBILITY. Except as described below, all regular-status employees of the Company and its participating subsidiaries who have been so employed for at least six months and work more than twenty hours per week will be eligible to participate in the Purchase Plan. Any employee who owns or would be deemed to own five percent or more of the voting power or value of all classes of stock of the Company will be ineligible to participate in the Purchase Plan. ADMINISTRATION. The Purchase Plan will be administered by the Board of Directors or a committee appointed by the Board of Directors. The Board of Directors may promulgate rules and regulations for the operation of the Purchase Plan, adopt forms for use in connection with the plan, decide any question of interpretation of the plan or rights arising thereunder and generally supervise the administration of the plan. RIGHT TO PURCHASE SHARES. Eligible employees may participate in the Purchase Plan by electing to contribute to the plan by means of a payroll deduction. Participants may contribute to the Purchase Plan from $10 to 10 percent of their total base salary during each pay period in the offering period. No employee's rights to acquire shares of Common Stock may accrue at a rate that exceeds $25,000 per calendar year. The $25,000 limit is based on the fair market value of the shares as of the relevant enrollment date. At the end of each six-month offering period, June 30 and December 31 each year, the Company will apply the amount contributed by the participant during the offering period to the purchase of whole shares of Common Stock reserved under the Purchase Plan. The purchase price per share of Common Stock is equal to the lesser of 85 percent of the fair market value of the Common Stock on the 13 first trading day of the offering period or the last trading day of the offering period. Any cash amount remaining after the purchase of whole shares will be retained in the participant's account for application on the next purchase date. Neither payroll deductions credited to a participant's account nor any rights under the Purchase Plan may be assigned, transferred, pledged or otherwise disposed of in any way by the participant. Upon termination of a participant's employment because of death, retirement or disability, the payroll deductions credited to the participant's account will be used to purchase shares of Common Stock on the next purchase date under the plan. Any remaining balance is returned to the participant or his or her beneficiary. A participant may withdraw the entire accumulated balance in his or her account and terminate participation in the Purchase Plan by giving written notice to the Company, except that no amounts may be withdrawn within 15 days prior to the last day of an offering period. AMENDMENTS. The Board of Directors of the Company may amend the Purchase Plan, except that without stockholder approval, the Board of Directors may not increase the number of shares reserved for issuance under the plan, permit the sale of shares to noneligible employees, materially increase benefits or materially modify eligibility requirements. The Board of Directors may terminate the Purchase Plan at any time. Upon termination, amounts credited to participants' accounts will be returned to participants. UNITED STATES TAX INFORMATION The Purchase Plan, and the right of participants to make purchases thereunder, are intended to qualify under the provisions of Sections 421 and 423 of the Internal Revenue Code of 1986, as amended (the "Code"). Under these provisions, no income will be taxable to a participant until the shares purchased under the Purchase Plan are sold or otherwise disposed of. However, the participant will generally be subject to tax upon the sale or other disposition of the shares. If the shares are sold or otherwise disposed of more than two years from the first day of the offering period and one year from the date the shares are purchased (the "Holding Periods"), the participant will recognize ordinary income measured as the lesser of (a) the excess of the fair market value of the shares at the time of such sale or disposition over the purchase price, or (b) an amount equal to 15 percent of the fair market value of the shares as of the first day of the offering period. Any additional gain will be treated as long-term capital gain. If the shares are sold or otherwise disposed of before the expiration of the Holding Periods, the participant will recognize ordinary income generally measured as the excess of the fair market value of the shares on the date the shares are purchased over the purchase price. Any additional gain or loss on such sale or disposition will be long-term or short-term capital gain or loss, depending on the holding period. The Company is not entitled to a deduction for amounts taxed as ordinary income or capital gain to a participant except to the extent of ordinary income recognized by participants upon a sale or disposition of shares prior to the expiration of the Holding Periods. The foregoing summary of the effect of United States federal income taxation upon the participant and the Company in connection with the Purchase Plan does not purport to be complete, and reference should be made to the applicable provisions of the Code. In addition, this summary does not discuss the provisions of the income tax laws of any municipality, state or foreign country in which the participant may reside. REQUIRED VOTE The approval of the amendment to the Purchase Plan requires the affirmative vote of a majority of the Votes Cast on this matter at the Annual Meeting. See "Information Concerning Solicitation and Voting-- General". THE BOARD OF DIRECTORS RECOMMENDS THAT THE STOCKHOLDERS VOTE "FOR" APPROVAL OF THE AMENDMENT TO THE PURCHASE PLAN. 14 PROPOSAL 3: RATIFICATION OF APPOINTMENT OF INDEPENDENT ACCOUNTANTS On May 13, 1997, the Board of Directors appointed Price Waterhouse LLP to act as the independent accountants of the Company for the fiscal year ending March 28, 1998, subject to ratification of the appointment by the stockholders. Price Waterhouse LLP has served as the Company's independent accountants for the last ten fiscal years. Representatives of Price Waterhouse LLP have been invited and are expected to attend the Annual Meeting, will be given the opportunity to make a statement if they wish to do so and are expected to be available to respond to appropriate questions.

For this purpose, the right to purchase Shares accrues on the Purchase Date of an Offering Period. This section shall be interpreted to permit an Employee to purchase the maximum number of Shares permitted under Section 423(b)(8) of the Code and regulations and interpretations adopted thereunder. 3.4 VOLUNTARY PARTICIPATION. Participation in the Plan shall be voluntary. ARTICLE IV PAYROLL DEDUCTIONS -5- 4.1 PAYROLL DEDUCTION AUTHORIZATION. An Employee may contribute to the Plan only by means of payroll deduction. A Payroll Deduction Authorization Form must be filed with the enrolling individual's payroll office not less than 15 days prior to the Enrollment Date as of which the payroll deductions are to take effect. 4.2 AMOUNT OF DEDUCTIONS. A Participant may specify that he or she desires to make contributions to the Plan at a rate not less than $10.00 and not more than ten percent (10%) of the Participant's Compensation during each pay period in the Offering Period, or such other minimum or maximum percentages as the Plan Administrator shall establish from time to time. Such specification shall apply during any period of continuous participation in the Plan, unless modified or terminated as provided in Section 4.5 or as otherwise provided in the Plan. If a payroll deduction cannot be made in whole or in part because the Participant's pay for the period in question is insufficient to fund the deduction after having first withheld all the amounts otherwise deductible from his or her pay, the amount that was not withheld cannot be made up by the Participant nor will it be withheld from subsequent paychecks. If payroll deductions are made by a Participating Subsidiary, that corporation will promptly remit the amount of the deduction to the Corporation. 4.3 COMMENCEMENT OF DEDUCTIONS. Payroll deductions for a Participant shall commence with the first paycheck following the Enrollment Date of the Offering for which his or her Payroll Deduction Authorization Form is effective and shall continue indefinitely, unless modified or terminated as provided in Section 4.5 or as otherwise provided in the Plan. 4.4 ACCOUNTS. All payroll deductions made for a Participant shall be credited to his or her Account under the Plan. Following each Purchase Date, the Plan Administrator shall promptly deliver a report to each Participant setting forth the aggregate payroll deductions credited to such Participant's Account during the preceding six months and the number of Shares purchased. 4.5 MODIFICATION OF AUTHORIZED DEDUCTIONS. (a) Participant may, prior to the commencement of each Offering Period in which he or she will be a Participant, increase or reduce the amount of his or her payroll deduction, effective for all subsequent payroll periods, by completing an amended Payroll Deduction Authorization Form and filing it with his or her payroll office in accordance with Section 4.1; provided, however that no modification in a Participant's payroll deduction shall cause such Participant's contribution to be less than $10.00 or more than ten percent (10%) of such Participant's compensation during any pay period. (b) A Participant may at any time discontinue his or her payroll deductions by completing an amended Payroll Deduction Authorization Form and filing it with his or her payroll office, after which the Participant's participation in the Offering will terminate without automatic re-enrollment under Section 3.2(c), and the payroll deductions credited to such Participant's account shall be returned to the Participant. -6- (c) For purposes of this Section 4.5, an amended Payroll Deduction Authorization Form shall be effective for a specific pay period when filed at least 15 days prior to the last day of such period. ARTICLE V PURCHASES OF SHARES 5.1 PURCHASE OF SHARES. Subject to the limitations of Article VI, on each Purchase Date in an Offering Period the Corporation shall apply the amount credited to each Participant's Account to the purchase of as many full Shares that may be purchased with such amount at the price set forth in Section 5.2, and shall issue such Shares to the Participant. Payment for shares purchased under the Plan will be made only through payroll withholding in accordance with Article IV. 5.2 PRICE. The price of Shares to be purchased under Section 5.1 on any Purchase Date shall be the lower of: (a) Eighty-five percent (85%) of the fair market value of the shares on the Enrollment Date of the Offering; or (b) Eighty-five percent (85%) of the fair market value of the Shares on the Purchase Date of the Offering, provided that in no event shall the price be less than the book value per share of the Shares on the Purchase Date. For this purpose, the book value per share shall equal the aggregate book value of the Corporation on a consolidated basis (total assets minus total liabilities) at the end of the Company's fiscal quarter that is at the midpoint of the Offering Period, divided by the total number of shares of Common Stock (or common stock equivalents) outstanding at the end of the Company's fiscal quarter ended immediately prior to the Purchase Date. 5.3 FAIR MARKET VALUE. (a) The fair market value of the Shares on any date shall be equal to the closing price of such shares on the Valuation Date, as reported on the NASDAQ National Market System or such other quotation system that supersedes it. (b) If prices for the Shares are not publicly quoted, the fair market value of the Shares shall be determined by the Plan Administrator in good faith. Such determination shall be conclusive and binding on all persons. 5.4 UNUSED CONTRIBUTIONS. Any amount credited to a Participant's Account and remaining therein immediately after a Purchase Date because it was less than the amount required to purchase a full Share shall be carried forward in such Participant's Account for application on the next succeeding Purchase Date. No interest will be paid on the amounts accumulated. -7- 5.5 DELIVERY AND CUSTODY OF SHARES. Shares purchased by Employees pursuant to the Plan shall be delivered to the Employee or to an investment or financial firm appointed by the Plan Administrator to act as custodian on behalf of the Employee. ARTICLE VI TERMINATION AND WITHDRAWAL 6.1 TERMINATION OF EMPLOYMENT. Upon termination of a Participant's Employment for any reason other than as set forth in Section 6.2, the payroll deductions credited to such Participant's Account shall be returned to the Participant. A Participant shall have no right to acquire Shares on any Purchase Date subsequent to termination of his or her Employment. 6.2 TERMINATION UPON DEATH, RETIREMENT OR DISABILITY. Upon termination of the Participant's Employment because of his or her Death, Retirement or Disability, the payroll deductions credited to his or her Account shall be used to purchase Shares as provided in Article V on the next Purchase Date.

A Participant may withdraw the entire amount credited to his or her Account under the Plan and thereby terminate participation in the current Offering at any time by giving written notice to the Corporation, but in no case may a Participant withdraw amounts within the 15 days immediately preceding a Purchase Date for that Offering. Any amount withdrawn shall be paid to the Participant promptly after receipt of proper notice of withdrawal and no further payroll deductions shall be made unless a Payroll Deduction Authorization Form directing further deductions is or has been submitted. ARTICLE VII SHARES PURCHASED UNDER THE PLAN 7.1 SOURCE AND LIMITATION OF SHARES. (a) The Corporation has reserved for sale under the Plan 700,000 shares of its Common Stock, subject to adjustment upon changes in capitalization of the Corporation as provided in Section 9.2. Shares sold under the Plan may be newly issued shares or shares reacquired in private transactions or open market purchases, but all shares sold under the Plan regardless of source shall be counted against the 700,000 Share limitation. -8- (b) If there is an insufficient number of Shares to permit the full exercise of all existing rights to purchase Shares, or if the legal obligations of the Corporation prohibit the issuance of all Shares purchasable upon the full exercise of such rights, the Plan Administrator shall make a pro rata allocation of the Shares remaining available in as nearly a uniform and equitable manner as possible, based pro rata on the aggregate amounts then credited to each Participant's Account. In such event, payroll deductions to be made shall be reduced accordingly and the Plan Administrator shall give written notice of such reduction to each Participant affected thereby. Any amount remaining in a Participant's Account immediately after all available Shares have been purchased will be promptly remitted to such Participant. Determination by the Plan Administrator in this regard shall be final, binding and conclusive on all persons. No payroll deductions shall be permitted under the Plan at any time when no Shares are available. 7.2 DELIVERY OF SHARES. The rights to purchase Shares granted pursuant to this Plan will in all respects be subject to the terms and conditions of the Plan, as interpreted by the Plan Administrator from time to time. The Participant shall have no interest in Shares purchasable under the Plan until payment for the Shares has been completed at the close of business on the relevant Purchase Date. The Plan provides only an unfunded, unsecured promise by the Employer to pay money or property in the future. Except with respect to the Shares purchased on a Purchase Date, an Employee choosing to participate in the Plan shall have no greater rights than an unsecured creditor of the Corporation. After the purchase of the Shares, the Participant shall be entitled to all rights of a stockholder of the Corporation. ARTICLE VIII ADMINISTRATION 8.1 PLAN ADMINISTRATOR. At the discretion of the Board of Directors, the Plan shall be administered by the Board of Directors or by a Committee appointed by the Board of Directors in accordance with Rule 16b-3 under the Securities Exchange Act of 1934, as in effect from time to time.

The grant of a right to purchase Shares pursuant to this Plan shall not affect in any way the right or power of the Corporation to make adjustments, reclassification, reorganizations or other changes of its capital or business structure or to merge or to consolidate or to dissolve, liquidate or transfer all or any part of its divisions, subsidiaries, business or assets. 9.2 RECAPITALIZATION. Subject to any required action by the stockholders, the number of Shares covered by the Plan as provided in Section 7.1 and the price per Share shall be proportionately adjusted for any increase or decrease in the number of issued Shares of the Corporation resulting from a subdivision or consolidation of Shares or the payment of a stock dividend (but only on the Shares). The determination of whether an adjustment shall be made and the manner of any adjustment shall be made by the Plan Administrator without any further approval from the stockholders, which determination shall be conclusive. 9.3 CONSOLIDATION OR MERGER.

Any Employee who leaves the Employer directly to perform services in the Armed Forces of the United States or in the United States Public Health Service under conditions entitling the Employee to reemployment rights provided by the laws of the United States, shall be on military leave. An Employee's military leave shall expire if the Employee voluntarily resigns from the Employer during the leave or if he or she fails to make application for reemployment within the period specified by such law for the preservation of employment rights. In -10- such event, the individual's employment shall terminate by resignation on the day the military leave expires. ARTICLE XI STOCKHOLDER APPROVAL AND RULINGS The Plan is expressly made subject (a) to the affirmative vote of the holders of a majority of the outstanding shares of the Corporation present in person or by proxy at a meeting of stockholders within 12 months after the date the Plan is adopted and (b) at the Corporation's election, to the receipt by the Corporation from the Internal Revenue Service of a ruling in scope and content satisfactory to counsel to the Corporation, affirming the qualification of the Plan within the meaning of Section 423 of the Code.

In that case, the Account of each Participant shall forthwith be paid to the Participant. ARTICLE XII MISCELLANEOUS PROVISIONS 12.1 AMENDMENT AND TERMINATION OF THE PLAN.

Neither payroll deductions credited to a Participant's Account nor any rights with regard to the purchase of Shares under the Plan may be assigned, transferred, pledged or otherwise disposed of in any way by the Participant except as provided in Section 6.2, and any attempted assignment, transfer, pledge, or other disposition shall be null and void. The Corporation may treat any such act as an election to withdraw funds in accordance with Section 6.3. 12.3 USE OF FUNDS. All payroll deductions received or held by the Corporation under the Plan may be used by the Corporation for any corporate purposes and the Corporation shall not be obligated to segregate the payroll deductions. 12.4 EXPENSES.

The Corporation shall make every reasonable effort to effect such registration or qualification or to obtain such consent or approval. 12.7 PLAN NOT A CONTRACT OF EMPLOYMENT. The Plan is strictly a voluntary undertaking on the part of the Employer and shall not constitute a contract between the Employer and any Employee, or consideration for an inducement or a condition of the employment of an Employee. Except as otherwise required by law, nothing contained in the Plan shall give any Employee the right to be retained in the service of the Employer or to interfere with or restrict the right of the Employer, which is hereby expressly reserved, to discharge or retire any Employee at any time, with or without cause and with or without notice.

The Secretary of the Corporation is hereby designated agent for service of legal process on the Plan. -12- 12.9 NOTICE. All notices or other communications by a Participant to the Corporation under or in connection with the Plan shall be deemed to have been duly given when received by the Plan Administrator.
