 ARTICLE I 
 Establishment
and Purpose 
 Apogee Enterprises, Inc. (the “Company”) has adopted this Apogee Enterprises, Inc. 2021 Deferred Compensation Plan for Non-Employee Directors, applicable to Compensation deferred under Compensation Deferral Agreements submitted on and after the Effective Date. 

The purpose of the Plan is to provide non-employee members of the Board of Directors of the Company with an
opportunity to defer receipt of a portion of directors fees. The Plan is not intended to meet the qualification requirements of Code Section 401(a), but is intended to meet the requirements of Code Section 409A, and shall be operated and
interpreted consistent with that intent. 
 The Plan constitutes an unsecured promise by the Company to pay benefits in the future. Participants in the Plan
shall have the status of general unsecured creditors of the Company. The Plan is unfunded for Federal tax purposes. Any amounts set aside to defray the liabilities assumed by the Company will remain the general assets of the Company and shall remain
subject to the claims of the Company’s creditors until such amounts are distributed to the Participants.

to a Participant from such Account as of the most recent Valuation Date.

	2.7	 Change in Control. Change in Control means, with respect to Company, any of the following events:
(i) a change in the ownership of the Company, (ii) a change in the effective control of the Company, or (iii) a change in the ownership of a substantial portion of the assets of the Company. 



Change in Ownership. For purposes of this Section, a change in the ownership of the Company occurs on the date on which any one person,
or more than one person acting as a group, acquires ownership of stock of the Company that, together with stock held by such person or group constitutes more than 50% of the total fair market value or total voting power of the stock of the Company.
The acquisition by a person or group owning more than 50% of the total fair market value or total voting power of the stock of such Company of additional shares of such Company shall not constitute a “change of the ownership” of such
Company. 
 Change in Effective Control. A change in the effective control of the Company occurs on the date on which either:
(i) a person, or more than one person acting as a group, acquires ownership of stock of the Company possessing 35% or more of the total voting power of the stock of the Company, taking into account all such stock acquired during the 12-month period ending on the date of the most recent acquisition, provided that the acquisition by a person or group owning more than 35% of the total fair market value or total voting power of the stock of such
Company of additional shares of such Company shall not constitute a “change of effective control” of such Company, or (ii) a majority of the members of the Company’s Board of Directors is replaced during any 12-month period by directors whose appointment or election is not endorsed by a majority of the members of such Board of Directors prior to the date of the appointment or election, but only if no other corporation
is a majority shareholder of the Company. 
 Change in Ownership of Substantial Portion of Assets. A change in the ownership of a
substantial portion of assets occurs on the date on which any one person, or more than one person acting as a group, other than a person or group of persons that is related to the Company, acquires assets from the Company that have a total gross
fair market value equal to or more than 40% of the total gross fair market value of all of the assets of the Company immediately prior to such acquisition or acquisitions, taking into account all such assets acquired during the 12-month period ending on the date of the most recent acquisition. A transfer of assets shall not be treated as a “change in the ownership of a substantial portion of the assets” when such transfer is made
to an entity that is controlled by the shareholders of the transferor corporation as determined under Treas. Reg. section 1.409A-3(i)(5)(vii)(B). 

An event constitutes a Change in Control with respect to a Participant only if the Participant performs services for the Company that has
experienced the Change in Control, or the Participant’s relationship to the affected Company otherwise satisfies the requirements of Treasury Regulation Section 1.409A-3(i)(5)(ii).

 ARTICLE III 

Eligibility and Participation 
  

	3.1	 Eligibility and Participation. All non-employee Directors may
enroll in the Plan. Directors become Participants on the date on which the first Compensation Deferral Agreement becomes irrevocable under Article IV. 


  

	3.2	 Duration. Only Directors may submit Compensation Deferral Agreements during an enrollment for a Plan
Year. On and after a Separation from Service, a Participant shall remain a Participant as long as his or her Account Balance is greater than zero (0). All Participants will continue to be credited with Earnings and during such time may continue to
make allocation elections as provided in Section 7.4. An individual shall cease being a Participant in the Plan when his Account has been reduced to zero (0). 



ARTICLE IV 
 Deferrals 

 

	4.1	 Deferral Elections, Generally. 



 

	 	(a)	 A Participant may make an initial election to defer Compensation by submitting a Compensation Deferral
Agreement during the enrollment periods established by the Committee and in the manner specified by the Committee, but in any event, in accordance with Section 4.2. Unless an earlier date is specified in the Compensation Deferral Agreement,
deferral elections with respect to a Compensation source become irrevocable on the latest date applicable to such Compensation source under Section 4.2. 


  


	 	(b)	 A Compensation Deferral Agreement that is not timely filed with respect to a service period or component of
Compensation, or that is submitted by a Participant who Separates from Service prior to the latest date such agreement would become irrevocable under Section 409A, shall be considered null and void and shall not take effect with respect to such
item of Compensation. The Committee may modify or revoke any Compensation Deferral Agreement prior to the date the election becomes irrevocable under the rules of Section 4.2. 



 

	 	(c)	 The Committee may permit different deferral amounts for each component of Compensation and may establish a
minimum or maximum deferral amount for each such component. Unless otherwise specified by the Committee in the Compensation Deferral Agreement, Participants may defer a minimum of 25% and a maximum of 100% of deferrable Compensation earned during a
Plan Year. 


  

	 	(d)	 The Participant shall specify on his or her Compensation Deferral Agreement the amount of Deferrals and whether
to allocate Deferrals to one or more Separation Accounts or to one or more Specified Date Accounts. If no designation is made, payment will be made in a lump sum in the calendar year following the year in which Separation from Service occurs.

	4.2	 Timing Requirements for Compensation Deferral Agreements. 



 

	 	(a)	 Initial Eligibility. Newly eligible Directors may enroll within 30 days of the Effective Date or, if
later, the first day of the calendar quarter next following the date the Director is seated as a member of the Board of Directors. 



A Compensation Deferral Agreement filed under this paragraph applies to Compensation earned after the date that the Compensation Deferral
Agreement becomes irrevocable. 
  

	 	(b)	 Prior Year Election. Directors may defer Compensation by filing a Compensation Deferral Agreement no
later than December 31 of the year prior to the year in which the Compensation to be deferred is earned. A Compensation Deferral Agreement filed under this paragraph shall become irrevocable with respect to such Compensation not later than the
December 31 filing deadline. 


  

	 	(c)	 Certain Forfeitable Rights. With respect to a legally binding right to a payment in a subsequent year
that is subject to a forfeiture condition requiring the Participant’s continued services for a period of at least 12 months from the date the Participant obtains the legally binding right, the Committee may permit a Director to defer such
Compensation by filing a Compensation Deferral Agreement on or before the 30th day after the legally binding right to the Compensation accrues, provided that the Compensation Deferral Agreement is
submitted at least 12 months in advance of the earliest date on which the forfeiture condition could lapse. The Compensation Deferral Agreement described in this paragraph becomes irrevocable not later than such 30th day. If the forfeiture condition applicable to the payment lapses before the end of such 12-month period as a result of the Participant’s death or
disability (as defined in Treas. Reg. Section 1.409A-3(i)(4)) or upon a change in control (as defined in Treas. Reg. Section 1.409A-3(i)(5)), the Compensation
Deferral Agreement will be void unless it would be considered timely under another rule described in this Section. 


  

	 	(d)	 “Evergreen” Deferral Elections. The Committee, in its discretion, may provide that
Compensation Deferral Agreements will continue in effect for subsequent years or performance periods by communicating that intention to Participants in writing prior to the date Compensation Deferral Agreements become irrevocable under this
Section 4.2. An evergreen Compensation Deferral Agreement may be revoked or modified in writing prospectively by the Participant or the Committee with respect to Compensation for which such election remains revocable under this
Section 4.2.

A Compensation Deferral Agreement is deemed to be revoked for subsequent years if the Participant is not a Director as of the last permissible date for making elections under this
Section 4.2 or if the Compensation Deferral Agreement is cancelled in accordance with Section 4.5. 

  

	4.3	 Allocation of Deferrals. A Compensation Deferral Agreement may allocate Deferrals to one or more
Separation Accounts or to one or more Specified Date Accounts. The Committee may, in its discretion, establish in a written communication during enrollment a minimum deferral period for the establishment of a Specified Date Account (for example, the
second Plan Year following the year Compensation is first allocated to such Accounts). In the event a Participant’s Compensation Deferral Agreement allocates Compensation to a Specified Date Account that is payable in the year of deferral or
vesting, the Compensation Deferral Agreement shall be deemed to allocate the Deferral to the Participant’s Specified Date Account with the next earliest payment year. If the Participant has no other Specified Date Accounts, the Committee will
establish a Specified Date Account that pays in the second calendar year next following the year the Compensation was earned or, if subject to a vesting schedule, one calendar year after the calendar year in which the award becomes 100% vested.



  

	4.4	 Vesting. Participant Deferrals of cash Compensation shall be 100% vested at all times. Deferrals of
vesting awards of Compensation shall become vested in accordance with the provisions of the underlying award. 


  

	4.5	 Cancellation of Deferrals. The Committee may cancel a Participant’s Deferrals: (i) for the
balance of the Plan Year in which an Unforeseeable Emergency occurs, and (ii) during periods in which the Participant is unable to perform his or her duties due to a mental or physical impairment that can be expected to result in death or last
for a continuous period of at least six months, provided cancellation occurs by the later of the end of the taxable year of the Participant or the 15th day of the third month following the date
the Participant incurs the disability (as defined in this paragraph (ii)). 


 ARTICLE V 

Reserved. 
 ARTICLE VI 

Payments from Accounts 
  

	6.1	 General Rules. A Participant’s Accounts become payable upon the first to occur of the payment
events applicable to such Account under (i) Sections 6.2 or 6.3 (as elected) and (ii) Sections 6.4 through 6.6.

 Apogee Enterprises, Inc. Deferred Compensation Plan for Non-Employee Directors 

 

 Payment events and Payment Schedules elected by the Participant shall be set forth in a valid
Compensation Deferral Agreement that establishes the Account to which such elections apply in accordance with Article IV or in a valid modification election applicable to such Account as described in Section 6.9. 

Payment amounts are based on Account Balances as of the last Valuation Date of the month next preceding the month actual payment is made. 

 

	6.2	 Specified Date Accounts. 



Commencement. Payment is made or begins in the calendar year designated by the Participant for each Specified Date Account. 

Form of Payment. Payment will be made in a lump sum, unless the Participant elected to receive a Specified Date Account in annual
installments up to five years. 
 Notwithstanding any election of a form of payment by the Participant, upon a Separation from Service the
unpaid balance of any Specified Date Accounts with respect to which payments have not commenced shall be paid in a single lump sum in the calendar year next following the calendar year in which Separation from Service occurs. 

 

	6.3	 Separation from Service. Upon a Participant’s Separation from Service other than death, the
Participant is entitled to receive his or her Separation Accounts. 


 Commencement. All Separation Accounts commence
payment in the calendar year next following the calendar year in which Separation from Service occurs. 
 Form of Payment. Separation
Accounts will be paid in a single lump sum unless the Participant elected to receive a Separation Account in annual installments up to 10 years. 
  

	6.4	 Death. Notwithstanding anything to the contrary in this Article VI, upon the death of the Participant
(regardless of whether such Participant is a Director at the time of death), all remaining vested Account Balances shall be paid to his or her Beneficiary in a single lump sum no later than December 31 of the calendar year following the year of
the Participant’s death. 


  

	 	(a)	 Designation of Beneficiary in General. The Participant shall designate a Beneficiary in the manner and
on such terms and conditions as the Committee may prescribe. No such designation shall become effective unless filed with the Committee during the Participant’s lifetime. Any designation shall remain in effect until a new designation is filed
with the Committee; provided, however, that in the event a Participant designates his or her spouse as a Beneficiary, such designation shall be automatically revoked upon the dissolution of the marriage unless, following such dissolution, the
Participant submits a new designation naming the former spouse as a Beneficiary. A Participant may from time to time change his or her designated Beneficiary without the consent of a previously-designated Beneficiary by filing a new designation with
the Committee.

	 	(b)	 No Beneficiary. If a designated Beneficiary does not survive the Participant, or if there is no valid
Beneficiary designation, amounts payable under the Plan upon the death of the Participant shall be paid to the Participant’s spouse, or if there is no surviving spouse, then to the duly appointed and currently acting personal representative of
the Participant’s estate. 


  

	6.5	 Unforeseeable Emergency. A Participant who experiences an Unforeseeable Emergency may submit a written
request to the Committee to receive payment of all or any portion of his or her vested Accounts. If the emergency need cannot be relieved by cessation of Deferrals to the Plan, the Committee may approve an emergency payment therefrom not to exceed
the amount reasonably necessary to satisfy the need, taking into account the additional compensation that is available to the Participant as the result of cancellation of deferrals to the Plan, including amounts necessary to pay any taxes or
penalties that the Participant reasonably anticipates will result from the payment. The amount of the emergency payment shall be subtracted first from the Separation Accounts and then from the Specified Date Accounts, starting with the Account
having the latest commencement date until fully distributed, then continuing in this manner with the next latest Account until the full amount of the distribution is made. Emergency payments shall be paid in a single lump sum within the 90-day period following the date the payment is approved by the Committee. 


  

	6.6	 Administrative Cash-Out of Small Balances. Notwithstanding
anything to the contrary in this Article VI, the Committee may at any time and without regard to whether a payment event has occurred, direct in writing an immediate lump sum payment of the Participant’s Accounts if the balance of such
Accounts, combined with any other amounts required to be treated as deferred under a single plan pursuant to Code Section 409A, does not exceed the applicable dollar amount under Code Section 402(g)(1)(B), provided any other such
aggregated amounts are also distributed in a lump sum at the same time. 


  

	6.7	 Acceleration of or Delay in Payments. Notwithstanding anything to the contrary in this Article VI, the
Committee, in its sole and absolute discretion, may elect to accelerate the time or form of payment of an Account, provided such acceleration is permitted under Treas. Reg. Section 1.409A-3(j)(4). The
Committee may also, in its sole and absolute discretion, delay the time for payment of an Account, to the extent permitted under Treas. Reg. Section 1.409A-2(b)(7). 



 

	6.8	 Rules Applicable to Installment Payments. If a Payment Schedule specifies installment payments, payments
will be made beginning as of the payment commencement date for such installments and shall continue to be made in each subsequent payment period until the number of installment payments specified in the Payment Schedule has been paid. The amount of
each installment payment shall be determined by dividing (a) by (b),

 Apogee Enterprises, Inc. Deferred Compensation Plan for Non-Employee Directors 

 


	 	
where (a) equals the Account Balance as of the last Valuation Date in the month preceding the month of payment and (b) equals the remaining number of installment payments. For purposes
of Section 6.9, installment payments will be treated as a single form of payment. If an Account is payable in installments, the Account will continue to be credited with Earnings in accordance with Article VII hereof until the Account is
completely distributed. 

  

	6.9	 Modifications to Payment Schedules. A Participant may modify the Payment Schedule elected by him or her
with respect to an Account, consistent with the permissible Payment Schedules available under the Plan for the applicable Account, provided such modification complies with the requirements of this Section 6.9. 



 

	 	(a)	 Time of Election. The modification election must be submitted to the Committee not less than 12 months
prior to the date payments would have commenced under the Payment Schedule in effect prior to modification (the “Prior Election”). 


  

	 	(b)	 Date of Payment under Modified Payment Schedule. The date payments are to commence under the modified
Payment Schedule must be no earlier than five years after the date payment would have commenced under the Prior Election. Under no circumstances may a modification election result in an acceleration of payments in violation of Code
Section 409A. If the Participant modifies only the form, and not the commencement date for payment, payments shall commence on the fifth anniversary of the date payment would have commenced under the Prior Election. 



 

	 	(c)	 Irrevocability; Effective Date. A modification election is irrevocable when filed and becomes effective
12 months after the filing date. 


  

	 	(d)	 Effect on Accounts. An election to modify a Payment Schedule is specific to the Account or payment event
to which it applies, and shall not be construed to affect the Payment Schedules or payment events of any other Accounts. 



ARTICLE VII 
 Valuation of Account
Balances; Investments 
  

	7.1	 Valuation. Deferrals shall be credited to appropriate Accounts on the date such Compensation would have
been paid to the Participant absent the Compensation Deferral Agreement. Valuation of Accounts shall be performed under procedures approved by the Committee. 


  


	7.2	 Earnings Credit. Each Account will be credited with Earnings on each Business Day, based upon the
Participant’s investment allocation among a menu of investment options selected in advance by the Committee, in accordance with the provisions of this Article VII (“investment allocation”).

 Apogee Enterprises, Inc. Deferred Compensation Plan for Non-Employee Directors 

 


	7.3	 Investment Options. Investment options will be determined by the Committee. The Committee, in its sole
discretion, shall be permitted to add or remove investment options from the Plan menu from time to time, provided that any such additions or removals of investment options shall not be effective with respect to any period prior to the effective date
of such change. 


  

	7.4	 Investment Allocations. A Participant’s investment allocation constitutes a deemed, not actual,
investment among the investment options comprising the investment menu. At no time shall a Participant have any real or beneficial ownership in any investment option included in the investment menu, nor shall the Company or any trustee acting on its
behalf have any obligation to purchase actual securities as a result of a Participant’s investment allocation. A Participant’s investment allocation shall be used solely for purposes of adjusting the value of a Participant’s Account
Balances. 


 A Participant shall specify an investment allocation for each of his Accounts in accordance with procedures
established by the Committee. Allocation among the investment options must be designated in increments of 1%. The Participant’s investment allocation will become effective on the same Business Day or, in the case of investment allocations
received after a time specified by the Committee, the next Business Day. 
 A Participant may change an investment allocation on any Business
Day, both with respect to future credits to the Plan and with respect to existing Account Balances, in accordance with procedures adopted by the Committee. Changes shall become effective on the same Business Day or, in the case of investment
allocations received after a time specified by the Committee, the next Business Day, and shall be applied prospectively. 
  

	7.5	 Unallocated Deferrals and Accounts. If the Participant fails to make an investment allocation with
respect to an Account, such Account shall be invested in an investment option, the primary objective of which is the preservation of capital, as determined by the Committee. 



 

	7.6	 Valuations Final After 180 Days. The Participant shall have 180 days following the Valuation Date on
which the Participant failed to receive the full amount of Earnings and to file a claim under Article XI for the correction of such error. 



ARTICLE VIII 
 Administration 

 

	8.1	 Plan Administration. This Plan shall be administered by the Committee which shall have discretionary
authority to make, amend, interpret and enforce all appropriate rules and regulations for the administration of this Plan and to utilize its discretion to decide or resolve any and all questions, including but not limited to eligibility for benefits
and interpretations of this Plan and its terms, as may arise in connection with the Plan. Claims for benefits shall be filed with the Committee and resolved in accordance with the claims procedures in Article XI.

	8.2	 Administration Upon Change in Control. Upon a Change in Control, the Committee, as constituted
immediately prior to such Change in Control, shall continue to act as the Committee. The Committee, by a vote of a majority of its members, shall have the authority (but shall not be obligated) to appoint an independent third party to act as the
Committee. 


 Upon such Change in Control, the Company may not remove the Committee or its members, unless a majority of
Participants and Beneficiaries with Account Balances consent to the removal and replacement of the Committee. Notwithstanding the foregoing, the Committee shall not have authority to direct investment of trust assets under any rabbi trust described
in Section 10.2. 
 The Company shall, with respect to the Committee identified under this Section: (i) pay all reasonable expenses
and fees of the Committee, (ii) indemnify the Committee (including individuals serving as Committee members) against any costs, expenses and liabilities including, without limitation, attorneys’ fees and expenses arising in connection with
the performance of the Committee’s duties hereunder, except with respect to matters resulting from the Committee’s gross negligence or willful misconduct, and (iii) supply full and timely information to the Committee on all matters
related to the Plan, any rabbi trust, Participants, Beneficiaries and Accounts as the Committee may reasonably require. 
  

	8.3	 Withholding. The Company shall have the right to withhold from any payment due under the Plan (or with
respect to any amounts credited to the Plan) any taxes required by law to be withheld in respect of such payment (or credit). Withholdings with respect to amounts credited to the Plan shall be deducted from Compensation that has not been deferred to
the Plan. 


  

	8.4	 Indemnification. The Company shall indemnify and hold harmless each employee, officer, or director to
whom are delegated duties, responsibilities, and authority under the Plan or otherwise with respect to administration of the Plan, to the extent permitted or required by the Bylaws of the Company. 



 

	8.5	 Delegation of Authority. In the administration of this Plan, the Committee may, from time to time,
employ agents (including employees of the Company) and delegate to them such administrative duties as it sees fit, and may from time to time consult with legal counsel who shall be legal counsel to the Company.

	8.6	 Binding Decisions or Actions. The decision or action of the Committee in respect of any question arising
out of or in connection with the administration, interpretation and application of the Plan and the rules and regulations thereunder shall be final and conclusive and binding upon all persons having any interest in the Plan. 



ARTICLE IX 
 Amendment and Termination

  

	9.1	 Amendment and Termination. The Company may at any time and from time to time amend the Plan or may
terminate the Plan as provided in this Article IX. Each Company may also terminate its participation in the Plan. 


  

	9.2	 Amendments. The Company, by action taken by its Board of Directors, may amend the Plan at any time and
for any reason, provided that any such amendment shall not reduce the vested Account Balances of any Participant accrued as of the date of any such amendment or restatement (as if the Participant had incurred a voluntary Separation from Service on
such date). The Board of Directors of the Company may delegate to the Committee the authority to amend the Plan without the consent of the Board of Directors for the purpose of: (i) conforming the Plan to the requirements of law;
(ii) facilitating the administration of the Plan; (iii) clarifying provisions based on the Committee’s interpretation of the Plan documents; and (iv) making such other amendments as the Board of Directors may authorize.



  

	9.3	 Termination. The Company, by action taken by its Board of Directors, may terminate the Plan and pay
Participants and Beneficiaries their Account Balances in a single lump sum at any time, to the extent and in accordance with Treas. Reg. Section 1.409A-3(j)(4)(ix). 



 

	9.4	 Accounts Taxable Under Code Section 409A. The Plan is intended to constitute a plan
of deferred compensation that meets the requirements for deferral of income taxation under Code Section 409A. The Committee, pursuant to its authority to interpret the Plan, may sever from the Plan or any Compensation Deferral Agreement any
provision or exercise of a right that otherwise would result in a violation of Code Section 409A. 


 ARTICLE X

 Informal Funding 
  

	10.1	 General Assets. Obligations established under the terms of the Plan may be satisfied from the general
funds of the Company, or a trust described in this Article X. No Participant, spouse or Beneficiary shall have any right, title or interest whatever in assets of the Company. Nothing contained in this Plan, and no action taken pursuant to its
provisions, shall create or be construed to create a trust of any kind, or a fiduciary relationship, between the Company and any Participant, spouse, or Beneficiary. To the extent that any person acquires a right to receive payments hereunder, such
rights are no greater than the right of an unsecured general creditor of the Company.

	10.2	 Rabbi Trust. The Company may, in its sole discretion, establish a grantor trust, commonly known as a
rabbi trust, as a vehicle for accumulating assets to pay benefits under the Plan. Payments under the Plan may be paid from the general assets of the Company or from the assets of any such rabbi trust. Payment from any such source shall reduce the
obligation owed to the Participant or Beneficiary under the Plan. 


 If a rabbi trust is in existence upon the occurrence
of a Change in Control, the Company shall, upon such Change in Control, and on each anniversary of the Change in Control, contribute in cash or liquid securities such amounts as are necessary so that the value of assets after making the
contributions exceed 110% of the total value of all Account Balances. 
 ARTICLE XI 

Claims 
  

	11.1	 Filing a Claim. Any controversy or claim arising out of or relating to the Plan shall be filed in
writing with the Committee which shall make all determinations concerning such claim. Any claim filed with the Committee and any decision by the Committee denying such claim shall be in writing and shall be delivered to the Participant or
Beneficiary filing the claim (the “Claimant”). Notice of a claim for payments shall be delivered to the Committee within 90 days of the latest date upon which the payment could have been timely made in accordance with the terms of the Plan
and Code Section 409A, and if not paid, the Participant or Beneficiary must file a claim under this Article XI not later than 180 days after such latest date. If the Participant or Beneficiary fails to file a timely claim, the Participant
forfeits any amounts to which he or she may have been entitled to receive under the claim. 


  

	 	(a)	 In General. Notice of a denial of benefits (other than claims based on disability) will be provided
within 90 days of the Committee’s receipt of the Claimant’s claim for benefits. If the Committee determines that it needs additional time to review the claim, the Committee will provide the Claimant with a notice of the extension before
the end of the initial 90-day period. The extension will not be more than 90 days from the end of the initial 90-day period and the notice of extension will explain the
special circumstances that require the extension and the date by which the Committee expects to make a decision. 


  

	 	(b)	 Contents of Notice. If a claim for benefits is completely or partially denied, notice of such denial
shall be in writing. The notice of denial shall set forth the specific reasons for denial in plain language. The notice shall: (i) cite the pertinent provisions of the Plan document, and (ii) explain, where appropriate, how the Claimant
can perfect the claim, including a description of any additional material or information necessary to complete the claim and why such material or information is necessary. The claim denial also shall include an explanation of the claims review
procedures and the time limits applicable to such procedures, including the right to appeal the decision, the deadline by which such appeal must be filed and a statement of the Claimant’s right to bring a civil action.

	11.2	 Appeal of Denied Claims. A Claimant whose claim has been completely or partially denied shall be
entitled to appeal the claim denial by filing a written appeal with a committee designated to hear such appeals (the “Appeals Committee”). A Claimant who timely requests a review of the denied claim (or his or her authorized
representative) may review, upon request and free of charge, copies of all documents, records and other information relevant to the denial and may submit written comments, documents, records and other information relating to the claim to the Appeals
Committee. All written comments, documents, records, and other information shall be considered “relevant” if the information: (i) was relied upon in making a benefits determination, (ii) was submitted, considered or generated in
the course of making a benefits decision regardless of whether it was relied upon to make the decision, or (iii) demonstrates compliance with administrative processes and safeguards established for making benefit decisions. The review shall
take into account all comments, documents, records, and other information submitted by the Claimant relating to the claim, without regard to whether such information was submitted or considered in the initial benefit determination. The Appeals
Committee may, in its sole discretion and if it deems appropriate or necessary, decide to hold a hearing with respect to the claim appeal. 


  

	 	(a)	 In General. Appeal of a denied benefits claim (other than a disability benefits claim) must be filed in
writing with the Appeals Committee no later than 60 days after receipt of the written notification of such claim denial. The Appeals Committee shall make its decision regarding the merits of the denied claim within 60 days following receipt of the
appeal (or within 120 days after such receipt, in a case where there are special circumstances requiring extension of time for reviewing the appealed claim). If an extension of time for reviewing the appeal is required because of special
circumstances, written notice of the extension shall be furnished to the Claimant prior to the commencement of the extension. The notice will indicate the special circumstances requiring the extension of time and the date by which the Appeals
Committee expects to render the determination on review. The review will take into account comments, documents, records and other information submitted by the Claimant relating to the claim without regard to whether such information was submitted or
considered in the initial benefit determination. 


  

	 	(b)	 Contents of Notice. If a benefits claim is completely or partially denied on review, notice of such
denial shall be in writing. Such notice shall set forth the reasons for denial in plain language. 



  

	
	 Content Copyright ©2021 Newport Group, Inc. All Rights Reserved.

 Apogee Enterprises, Inc. Deferred Compensation Plan for Non-Employee Directors 

 

 The decision on review shall set forth: (i) the specific reason or reasons for the
denial, (ii) specific references to the pertinent Plan provisions on which the denial is based, (iii) a statement that the Claimant is entitled to receive, upon request and free of charge, reasonable access to and copies of all documents,
records, or other information relevant (as defined above) to the Claimant’s claim, and (iv) a statement of the Claimant’s right to bring a civil action. 
  

	11.3	 Claims Appeals Upon Change in Control. Upon a Change in Control, the Appeals Committee, as constituted
immediately prior to such Change in Control, shall continue to act as the Appeals Committee. The Company may not remove any member of the Appeals Committee, but may replace resigning members if 2/3rds of the members of the Board of Directors of the
Company and a majority of Participants and Beneficiaries with Account Balances consent to the replacement. 


 The Appeals
Committee shall have the exclusive authority at the appeals stage to interpret the terms of the Plan and resolve appeals under the Claims Procedure. 

The Company shall, with respect to the Committee identified under this Section: (i) pay its proportionate share of all reasonable expenses
and fees of the Appeals Committee, (ii) indemnify the Appeals Committee (including individual committee members) against any costs, expenses and liabilities including, without limitation, attorneys’ fees and expenses arising in connection
with the performance of the Appeals Committee hereunder, except with respect to matters resulting from the Appeals Committee’s gross negligence or willful misconduct, and (iii) supply full and timely information to the Appeals Committee on
all matters related to the Plan, any rabbi trust, Participants, Beneficiaries and Accounts as the Appeals Committee may reasonably require. 
  

	11.4	 Legal Action. A Claimant may not bring any legal action, including commencement of any arbitration,
relating to a claim for benefits under the Plan unless and until the Claimant has followed the claims procedures under the Plan and exhausted his or administrative remedies under Sections 11.1 and 11.2. No such legal action may be brought more than
twelve (12) months following the notice of denial of benefits under Section 11.2, or if no appeal is filed by the applicable appeals deadline, twelve (12) months following the appeals deadline. 



If a Participant or Beneficiary prevails in a legal proceeding brought under the Plan to enforce the rights of such Participant or any other
similarly situated Participant or Beneficiary, in whole or in part, the Company shall reimburse such Participant or Beneficiary for all legal costs, expenses, attorneys’ fees and such other liabilities incurred as a result of such proceedings.
If the legal proceeding is brought in connection with a Change in Control, the Participant or Beneficiary may file a claim directly with the trustee for reimbursement of such costs, expenses and fees. For purposes of the preceding sentence, the
amount of the claim shall be treated as if it were an addition to the Participant’s or Beneficiary’s Account Balance and will be included in determining the Company’s trust funding obligation under Section 10.2.

	11.5	 Discretion of Appeals Committee. All interpretations, determinations and decisions of the Appeals
Committee with respect to any claim shall be made in its sole discretion, and shall be final and conclusive. 


  

	11.6	 Arbitration. 


  


	 	(a)	 Prior to Change in Control. If, prior to a Change in Control, any claim or controversy between the
Company and a Participant or Beneficiary is not resolved through the claims procedure set forth in Article XI, such claim shall be submitted to and resolved exclusively by expedited binding arbitration by a single arbitrator. Arbitration shall be
conducted in accordance with the following procedures: 


 The complaining party shall promptly send written notice to the
other party identifying the matter in dispute and the proposed remedy. Following the giving of such notice, the parties shall meet and attempt in good faith to resolve the matter. In the event the parties are unable to resolve the matter within 21
days, the parties shall meet and attempt in good faith to select a single arbitrator acceptable to both parties. If a single arbitrator is not selected by mutual consent within ten Business Days following the giving of the written notice of dispute,
an arbitrator shall be selected from a list of nine persons each of whom shall be an attorney who is either engaged in the active practice of law or recognized arbitrator and who, in either event, is experienced in serving as an arbitrator in
disputes between employers and employees, which list shall be provided by the main office of either JAMS, the American Arbitration Association (“AAA”) or the Federal Mediation and Conciliation Service. If, within three Business Days of the
parties’ receipt of such list, the parties are unable to agree on an arbitrator from the list, then the parties shall each strike names alternatively from the list, with the first to strike being determined by the flip of a coin. After each
party has had four strikes, the remaining name on the list shall be the arbitrator. If such person is unable to serve for any reason, the parties shall repeat this process until an arbitrator is selected. 

Unless the parties agree otherwise, within 60 days of the selection of the arbitrator, a hearing shall be conducted before such arbitrator at
a time and a place agreed upon by the parties. In the event the parties are unable to agree upon the time or place of the arbitration, the time and place shall be designated by the arbitrator after consultation with the parties. Within 30 days of
the conclusion of the arbitration hearing, the arbitrator shall issue an award, accompanied by a written decision explaining the basis for the arbitrator’s award. 

In any arbitration hereunder, the Company shall pay all administrative fees of the arbitration and all fees of the arbitrator, except that the
Participant or Beneficiary may, if he/she/it wishes, pay up to one-half of those amounts. Each party shall pay its own attorneys’ fees, costs, and expenses, unless the arbitrator orders otherwise.

The prevailing party in such arbitration, as determined by the arbitrator, and in any enforcement or other court proceedings, shall be entitled, to the extent permitted by law, to reimbursement
from the other party for all of the prevailing party’s costs (including but not limited to the arbitrator’s compensation), expenses, and attorneys’ fees. The arbitrator shall have no authority to add to or to modify this Plan, shall
apply all applicable law, and shall have no lesser and no greater remedial authority than would a court of law resolving the same claim or controversy. The arbitrator shall, upon an appropriate motion, dismiss any claim without an evidentiary
hearing if the party bringing the motion establishes that it would be entitled to summary judgment if the matter had been pursued in court litigation. 

The parties shall be entitled to discovery as follows: Each party may take no more than three depositions. The Company may depose the
Participant or Beneficiary plus two other witnesses, and the Participant or Beneficiary may depose the Company, pursuant to Rule 30(b)(6) of the Federal Rules of Civil Procedure, plus two other witnesses. Each party may make such reasonable document
discovery requests as are allowed in the discretion of the arbitrator. 
 The decision of the arbitrator shall be final, binding, and non-appealable, and may be enforced as a final judgment in any court of competent jurisdiction. 
 This
arbitration provision of the Plan shall extend to claims against any parent, subsidiary, or affiliate of each party, and, when acting within such capacity, any officer, director, shareholder, Participant, Beneficiary, or agent of any party, or of
any of the above, and shall apply as well to claims arising out of state and federal statutes and local ordinances as well as to claims arising under the common law or under this Plan. 

Notwithstanding the foregoing, and unless otherwise agreed between the parties, either party may apply to a court for provisional relief,
including a temporary restraining order or preliminary injunction, on the ground that the arbitration award to which the applicant may be entitled may be rendered ineffectual without provisional relief. 

Any arbitration hereunder shall be conducted in accordance with the Federal Arbitration Act: provided, however, that, in the event of any
inconsistency between the rules and procedures of the Act and the terms of this Plan, the terms of this Plan shall prevail. 
 If any of the
provisions of this Section 11.6(a) are determined to be unlawful or otherwise unenforceable, in the whole part, such determination shall not affect the validity of the remainder of this section and this section shall be reformed to the extent
necessary to carry out its provisions to the greatest extent possible and to

insure that the resolution of all conflicts between the parties, including those arising out of statutory claims, shall be resolved by neutral, binding arbitration. If a court should find that
the provisions of this Section 11.6(a) are not absolutely binding, then the parties intend any arbitration decision and award to be fully admissible in evidence in any subsequent action, given great weight by any finder of fact and treated as
determinative to the maximum extent permitted by law. 
 The parties do not agree to arbitrate any putative class action or any other
representative action. The parties agree to arbitrate only the claims(s) of a single Participant or Beneficiary. 
  

	 	(b)	 Upon Change in Control. Upon a Change in Control, Section 11.6(a) shall not apply and any legal
action initiated by a Participant or Beneficiary to enforce his or her rights under the Plan may be brought in any court of competent jurisdiction. Notwithstanding the Appeals Committee’s discretion under Sections 11.3 and 11.5, the court shall
apply a de novo standard of review to any prior claims decision under Sections 11.1 through 11.3 or any other determination made by the Company, its Board of Directors, the Company, the Committee, or the Appeals Committee. 



ARTICLE XII 
 General Provisions

  

	12.1	 Assignment. No interest of any Participant, spouse or Beneficiary under this Plan and no benefit payable
hereunder shall be assigned as security for a loan, and any such purported assignment shall be null, void and of no effect, nor shall any such interest or any such benefit be subject in any manner, either voluntarily or involuntarily, to
anticipation, sale, transfer, assignment or encumbrance by or through any Participant, spouse or Beneficiary. Notwithstanding anything to the contrary herein, however, the Committee has the discretion to make payments to an alternate payee in
accordance with the terms of a domestic relations order (as defined in Code Section 414(p)(1)(B)). 


 The Company may
assign any or all of its liabilities under this Plan in connection with any restructuring, recapitalization, sale of assets or other similar transactions affecting the Company without the consent of the Participant. 

 

	12.2	 No Legal or Equitable Rights or Interest. No Participant or other person shall have any legal or
equitable rights or interest in this Plan that are not expressly granted in this Plan. Participation in this Plan does not give any person any right to be retained a Director. The Company makes no representations or warranties as to the tax
consequences to a Participant or a Participant’s beneficiaries resulting from a deferral of income pursuant to the Plan.

	12.3	 No Employment Contract. Nothing contained herein shall be construed to constitute a contract of
employment between a Director and the Company. 


  

	12.4	 Notice. Any notice or filing required or permitted to be delivered to the Committee under this Plan
shall be delivered in writing, in person, or through such electronic means as is established by the Committee. Notice shall be deemed given as of the date of delivery or, if delivery is made by mail, as of the date shown on the postmark on the
receipt for registration or certification. Written transmission shall be sent by certified mail to:

 ATTN: HUMAN RESOURCES 

Any notice or filing required or permitted to be given to a Participant under this Plan shall be sufficient if in writing or hand-delivered,
or sent by mail to the last known address of the Participant. 
  

	12.5	 Headings. The headings of Sections are included solely for convenience of reference, and if there is any
conflict between such headings and the text of this Plan, the text shall control. 


  

	12.6	 Invalid or Unenforceable Provisions. If any provision of this Plan shall be held invalid or
unenforceable, such invalidity or unenforceability shall not affect any other provisions hereof and the Committee may elect in its sole discretion to construe such invalid or unenforceable provisions in a manner that conforms to applicable law or as
if such provisions, to the extent invalid or unenforceable, had not been included. 


  

	12.7	 Lost Participants or Beneficiaries. Any Participant or Beneficiary who is entitled to a benefit from the
Plan has the duty to keep the Committee advised of his or her current mailing address. If benefit payments are returned to the Plan or are not presented for payment after a reasonable amount of time, the Committee shall presume that the payee is
missing. The Committee, after making such efforts as in its discretion it deems reasonable and appropriate to locate the payee, shall stop payment on any uncashed checks and may discontinue making future payments until contact with the payee is
restored. If the Committee is unable to locate the Participant or Beneficiary after five years of the date payment is scheduled to be made the Participant’s Account will be forfeited, provided that a Participant’s Account shall not be
credited with Earnings following the first anniversary of such date on which payment is to be made and further provided, however, that such benefit shall be reinstated, without further adjustment for interest, if a valid claim is made by or on
behalf of the Participant or Beneficiary for all or part of the forfeited benefit.

	12.8	 Facility of Payment to a Minor. If a distribution is to be made to a minor, or to a person who is
otherwise incompetent, then the Committee may, in its discretion, make such distribution: (i) to the legal guardian, or if none, to a parent of a minor payee with whom the payee maintains his or her residence, or (ii) to the conservator or
committee or, if none, to the person having custody of an incompetent payee. Any such distribution shall fully discharge the Committee, the Company, and the Plan from further liability on account thereof. 



 

	12.9	 Governing Law. The laws of the State of Minnesota shall govern the construction and administration of
the Plan. 


  

	12.10	 Compliance With Code Section 409A; No Guarantee. This Plan is intended to be
administered in compliance with Code Section 409A and each provision of the Plan shall be interpreted consistent with Code Section 409A. Although intended to comply with Code Section 409A, this Plan shall not constitute a guarantee to
any Participant or Beneficiary that the Plan in form or in operation will result in the deferral of federal or state income tax liabilities or that the Participant or Beneficiary will not be subject to the additional taxes imposed under
Section 409A. Neither the Company nor any Affiliate shall have any legal obligation to a Participant with respect to taxes imposed under Code Section 409A.
