Section 3.05. Nature of Account. The Stock Purchase Account is established solely for accounting purposes, and all dollar amounts credited to the Stock Purchase Account will remain part of the general assets of the Company or the Participating Affiliate (as the case maybe).

Section 4.01. Number of Shares. As of the Purchase Date next following the Crediting Date, the Plan Administration Agent shall purchase on the open market the number of whole shares of Common Stock that can be purchased at the price specified in Section 4.02 of the Plan with the entire credit balance in all Participants’ Stock Purchase Accounts (excluding any Participant who has notified the Company, in advance of that date and subject to such terms and conditions as the Committee in its sole discretion may impose, of the Participant’s election to receive the distribution of the entire credit balance in cash). The Plan Administration Agent shall purchase shares for all Participants in an omnibus account, with shares allocated to Participants in whole and fractional amounts based on their Account balances.

Section 4.02. Purchase Price. The purchase price for any Common Stock purchased under the Plan shall be the price paid in the open market by the Plan Administration Agent on the relevant purchase date on behalf of all Participants in the Plan.

Section 4.03. Limitations. Any provisions of the Plan to the contrary notwithstanding, no Participant will have the right to purchase shares of Common Stock under the Plan to the extent that, immediately after the grant, such Participant (or any other person whose stock would be attributed to such Participant pursuant to section 424(d) of the Code) would own capital stock of the Company or any parent or subsidiary of the Company and/or hold outstanding options to purchase such stock possessing five percent (5%) or more of the total combined voting power or value of all classes of the capital stock of the Company or of any parent or subsidiary of the Company.

Section 4.04. Reports to Participants. The Plan Administration Agent will issue quarterly statements to each Participant showing the number of shares purchased for his or her Stock Purchase Account in the preceding quarter and the total number of shares in the Participant’s Stock Purchase Account.

Section 4.05. Notice of Acceleration Date. The Company shall use reasonable commercial efforts to notify each Participant in writing at least ten days prior to any Acceleration Date. As of the Purchase Date immediately preceding the Acceleration Date, the Plan Administration Agent shall purchase the number of shares of Common Stock that can be purchased in accordance with Sections 4.01 and 4.02 above, and thereafter the Plan shall automatically terminate. Any payroll deductions set aside and all other cash credited to Stock Purchase Account shall be distributed to the Participants.

Section 5.01. Voluntary Withdrawal. A Participant may, in accordance with such terms and conditions as the Committee in its sole discretion may impose, withdraw from the Plan and cease making payroll deductions by filing with the Company a form provided for this purpose (or through such electronic medium as may be established by the Company). A Participant who withdraws from the Plan may re-enroll at any time to resume making payroll deduction as of any next following Payroll Date, subject to such terms and conditions as the Committee in its sole discretion may impose.

Section 5.02. Death. Subject to such terms and conditions as the Committee in its sole discretion may impose, upon the death of a Participant, no further amounts shall be credited to the Participant’s Stock Purchase Account other than payroll deductions made prior to the Participant’s death but not yet remitted to the Stock Purchase Account. Thereafter, all remaining payroll deductions shall be remitted in the ordinary course and purchases made in accordance with Sections 3.02 and 4.01 of the Plan until the remaining credit balance in such Participant’s Stock Purchase Account is exhausted, unless such Participant’s estate has notified the Company, in advance of that day and subject to such terms and conditions as the Committee in its sole discretion may impose, of its election to have all unremitted payroll deductions and the entire credit balance in such Participant’s Stock Purchase Account distributed in cash within 30 days after the Participant’s death or at such earlier time as the Committee in its sole discretion may decide. Each Participant, however, may designate one or more beneficiaries who, upon death, are to receive the Common Stock or the amount that otherwise would have been distributed or paid to the Participant’s estate and may change or revoke any such designation from time to time. No such designation, change or revocation will be effective unless made by the Participant in writing and filed with the Company during the Participant’s lifetime. Unless the Participant has otherwise specified the beneficiary designation, the beneficiary or beneficiaries so designated will become fixed as of the date of the Participant’s death so that, if a beneficiary survives the Participant but dies before the receipt of the payment due such beneficiary, the payment will be made to such beneficiary’s estate.

Section 5.03. Termination of Employment. Subject to such terms and conditions as the Committee in its sole discretion may impose, upon a Participant’s termination of employment with the Company or a Participating Affiliate, no further amounts shall be credited to the Participant’s Stock Purchase Account other than payroll deductions made prior to the Participant’s termination of employment but not yet remitted to the Stock Purchase Account. Thereafter, all remaining payroll deductions shall be remitted in the ordinary course and purchases made in accordance with Sections 3.02 and 4.01 of the Plan until the remaining credit balance in such Participant’s Stock Purchase Account is exhausted, unless such Participant has notified the Company, in advance of that day and subject to such terms and conditions as the Committee in its sole discretion may impose, of the Participant’s election to receive all unremitted payroll deductions and the entire credit balance in such Participant’s Stock Purchase Account in cash within 30 days after the Participant’s termination of employment. For purposes of this Section 6.03, a transfer of employment to any Participating Affiliate, or a leave of absence which has been approved by the Committee, will not be deemed a termination of employment as a Regular Employee. If shares remain in a Participant’s Stock Purchase Account after three months following termination of employment, the Participant will be sent a letter giving the Participant the option to either (i) direct the Plan Administration Agent to sell the shares, (ii) transfer the shares to a broker selected by the Participant or (iii) transfer the shares to Apogee’s transfer agent.

Section 5.04. Sale of Stock. A Participant may direct the Plan Administration Agent to sell a portion or all of the shares held in his or her Stock Purchase Account. Upon receipt of the direction, the Plan Administration Agent will sell the designated shares at the prevailing market price. Following the second sale in any calendar year by a Participant of shares held in his or her Stock Purchase Account, all payroll deductions and contributions by the Company or the Participating Affiliate will cease for a period of six months, after which time the Participant may resume participation in the Plan. If a Participant makes a third request for the sale of shares in any calendar year, the Participant’s participation in the Plan shall cease, the Participant’s Stock Purchase Account shall be closed, and the Participant shall not be eligible to participate in the Plan for a period of at least six months after the date of the Participant’s third request for such sale of shares.

Section 6.01. Nontransferable Right to Purchase. The right to purchase Common Stock hereunder may not be assigned, transferred, pledged or hypothecated (whether by operation of law or otherwise), except as provided in Section 5.02 of the Plan, and will not be subject to execution, attachment or similar process. Any attempted assignment, transfer, pledge, hypothecation or other disposition or levy of attachment or similar process upon the right to purchase will be null and void and without effect.

Section 6.02. Nontransferable Account. Except as provided in Section 5.02 of the Plan, the amounts credited to a Stock Purchase Account may not be assigned, transferred, pledged or hypothecated in any way, and any attempted assignment, transfer, pledge, hypothecation or other disposition of such amounts will be null and void and without effect.

Section 7.01. Form of Ownership. The Common Stock purchased under the Plan may be evidenced in such manner as the Committee may deem appropriate, including book entry registration or issuance of a stock certificate or certificates, which certificate or certificates shall be held by the Company or held in nominee name by the stock transfer agent or brokerage service selected by the Company to provide such services for the Plan.

Section 7.02. Automatic Dividend Reinvestment. Any and all cash dividends paid on shares of Common Stock held in a Participant’s Stock Purchase Account shall be credited to the Participant’s Stock Purchase Account on the basis of the number of shares in the Participant’s Stock Purchase Account on the date of record of the dividend and shall be reinvested to acquire shares of Common Stock purchased in the open market by the Plan Administration Agent. Purchases of Common Stock under this Section 7.02 will be normally purchased within ten business days of the dividend payment date, depending upon market conditions. The price per share of the Common Stock purchased pursuant to this Section 7.02 shall be the price per share at which the Common Stock is actually purchased in the open market for the relevant period on behalf of all participants in the Plan. All shares of Common Stock acquired under this Section 7.02 will be held in the Plan in the same name as the Common Stock upon which the cash dividends were paid.
