 INTRODUCTION 

This Executive Deferred Compensation Plan of Allegro MicroSystems, LLC (the “Plan”) was authorized by Allegro MicroSystems, LLC (the
“Company”) to be applicable effective on and after April 1, 1995. 
 Since its initial effective date, the Plan has been amended as follows: 

 

	 	•	 	 By restatement effective as of January 1, 2008, to comply with the provisions of Section 409A of the
Internal Revenue Code. 


  

	 	•	 	 By amendment effective as of August 1, 2009, to cease contributions and to pay out certain benefits, as
permitted by the terms of the Plan and of Section 409A of the Internal Revenue Code. 


  

	 	•	 	 By restatement effective as of January 1, 2011, to again permit amounts to be deferred under the Plan and to
make certain other changes desired by the Company. 


  

	 	•	 	 By restatement effective as of January 1, 2013, to provide that elections must be made for each Plan Year or
Performance Period, to limit the amounts that may be deferred from Base Salary to 50%, to permit deferrals to a specified date that may be prior to termination of employment, and make certain other administrative changes in connection with transfer
of the Plan’s administration to a third party administrator and the addition of daily valuation of accounts. 


  

	 	•	 	 By restatement effective as of September 15, 2015, to allow additional forms of payment, provide for
immediate vesting of Company contributions credited to a Member’s account, allow deferrals to be made in dollar amounts in addition to percentages, reflect the Company’s transition to an LLC, to allow Members to defer up to 90% of Base
Salary and make other clarifying changes. 


 The Plan is now amended and restated, effective as of September 15, 2015 (except as
otherwise noted), to allow installment payment elections regardless of account balance, permit payment as soon as administratively feasible but up to 90 days following a payment event, provide for payments upon termination date anniversaries rather
than successive Februarys following termination of employment and clarify that participants are required to make a payment election triggered by their separation date but permitted to also elect a fixed payment date that may occur prior to
separation. 
 The Plan is intended to promote extraordinary contributions by eligible executives towards the success of the Company by providing such
executives with an opportunity to defer a portion of compensation they may receive as base salary or as a bonus under a bonus program maintained by the Company and to restore Safe Harbor Company Matching Contributions lost under the Allegro
MicroSystems, LLC Employees’ Retirement Savings Plan because of the application of the limitation on compensation imposed by Code Section 401 (a)(17) or by reason of the deferral of an eligible executive’s base salary or bonus under
this Plan. 
 The Plan is unfunded and is maintained by the Company for the purpose of providing deferred compensation for a select group of management or
highly-compensated employees. 
 The Plan reads as hereinafter set forth.

August 1, 2009; provided, however, that no portion of his or her Base Salary or Bonus for any period beginning on or after January 1, 2011 was deferred under the Plan unless such Member first filed a Deferral Agreement with the
Administrative Committee on or after October 1, 2010. 


 Effective January 1, 2011, each other Eligible Employee
became a Member as of the earliest of (i) January 1, 2011 if such Member first filed a Deferral Agreement with the Administrative Committee on or after October 1, 2010 and before January 1, 2011, (ii) the date on or after
January 1, 2011 such Member first filed a Deferral Agreement with the Administrative Committee, or (iii) the first day of the first calendar year during which the amount of Safe Harbor Company Matching Contributions made on behalf of an
Eligible Employee under the Savings Plan (as those terms are defined in the Savings Plan) are curtailed due to the limitation on compensation imposed by Code Section 401(a)(17). 

Effective January 1, 2013, each other Eligible Employee shall become a Member as of the earlier of clause (ii) or (iii) of the preceding
paragraph. 
 However, an Eligible Employee’s Deferral Agreement shall be effective for purposes of deferring a Base Salary or Bonus
only as provided in Article 3. 
  

	 	(b)	 A Member’s Deferral Agreement shall be in writing (electronic or otherwise) and be properly completed upon
a form approved by the Administrative Committee, which shall be the sole judge of the proper completion thereof. Such Deferral Agreement shall provide for the deferral of Base Salary or Bonus. The Deferral Agreement may include such other provisions

 ARTICLE 3. DEFERRAL ACCOUNT 

 

	3.01	 Deferral Elections  



Except as otherwise provided in Section 3.02 and subject to the provisions of Section 3.03, an Eligible Employee may elect to defer:

  

	 	(a)	 A portion of his or her Base Salary otherwise earned and payable during a Plan Year. The election to defer the
portion of Base Salary for any Plan Year must be made prior to the last business day of the calendar year preceding the beginning of such Plan Year. 


  

	 	(b)	 All or any portion of his or her Bonus earned for services he or she performs in the one-year Performance Period under the Allegro MicroSystems, LLC Annual Incentive Plan. The election to defer all or any portion of Bonus under the Allegro MicroSystems, LLC Annual Incentive Plan must be made on or
before the date that is six months before the end of the Performance Period for such plan. 


  

	 	(c)	 All or any portion of the Bonus earned for services such Eligible Employee performs in the applicable
three-year Performance Period under the Allegro MicroSystems, LLC Long-Term Cash Incentive Plan. The election to defer all or any portion of Bonus under the Allegro MicroSystems, LLC Long-Term Cash Incentive Plan must be made during the annual
salary enrollment window that falls within first year of the Performance Period for such plan. 


  

	3.02	 Special Rules for Initial Deferral Elections  



Subject to the provisions of Section 3.03, if an employee becomes an Eligible Employee after the beginning of any Plan Year or Performance
Period, he or she may elect to defer Base Salary and/or Bonus by filing a Deferral Agreement with the Administrative Committee as follows: 
  

	 	(a)	 With respect to Base Salary or Bonus(es) payable under the Allegro MicroSystems, LLC Annual Incentive Plan, the
Deferral Agreement(s) must be filed within 30 days following the date he or she becomes an Eligible Employee. 


  

	 	(b)	 With respect to Bonus payable under the Allegro MicroSystems, LLC Long-Term Cash Incentive Plan, the Deferral
Agreement must be filed within 30 days following the date he or she becomes an Eligible Employee, provided such date is within the first one-year period of the three-year Performance Period.



 Any deferral of Base Salary for a Plan Year under this Section 3.02 shall apply only to Base Salary to be paid for
services performed in such Plan Year after such election is effective. 
 Any deferral of a Bonus for a Performance Period under this
Section 3.02 shall apply only for the “remaining portion” of the Bonus to be paid for services performed in such Performance Period after the election is effective and for the Bonus paid for services in any Performance Period
beginning after such election is effective for which the deferral election deadline under Section 3.01 has passed. The “remaining portion” of the Bonus shall be determined by multiplying the Bonus for that Performance Period by a fraction,
the numerator of which is the number of days remaining in the Performance Period after the election becomes effective and the denominator is the total number of days in such Performance Period. 

  
 4 














	3.03	 Procedures and Restrictions 



 

	 	(a)	 An Eligible Employee may defer: 



 

	 	(i)	 up to 90% of his or her Base Salary for the Plan Year to which the election applies; and/or



  

	 	(ii)	 up to 100% of any Bonus for the Performance Period to which the election applies. 



Notwithstanding the foregoing, if there will not be sufficient Base Salary or Bonus remaining to deduct mandated tax withholdings and/or
implement other deferral or deduction elections in effect for the Eligible Employee, the deferral election(s) under this subparagraph shall be reduced to the extent necessary to satisfy required withholdings or other elections in effect. Any
deferral elections under this paragraph may be made either in 1% increments or in dollar amounts. In its sole discretion, the Administrative Committee may establish such other maximum or minimum limits on the amount of Base Salary or Bonus an
Eligible Employee may defer as it deems appropriate. Eligible Employees shall be given written notice of any such limits at least ten business days prior to the date they take effect. 

 

	 	(b)	 An Eligible Employee’s election to defer Base Salary for any Plan Year or Bonus for any Performance Period
shall be effective on the last day the deferral of such Base Salary or Bonus may be elected under Section 3.01 or 3.02, as the case may be. An Eligible Employee may revoke or change his or her election to defer Base Salary or Bonus at any time
prior to the date the election becomes effective. 


 Prior to January 1, 2013, deferral elections remained in effect
until revoked or changed by an Eligible Employee. Effective for Plan Years and Performance Periods beginning on and after January 1, 2013, deferral elections shall expire as of the last day of the Plan Year or Performance Period to which they
apply. Accordingly, an Eligible Employee must make a separate election for each Plan Year and Performance Period prior to the deadline prescribed by Section 3.01 or 3.02, as applicable. 

In the event more than one deferral election is made with respect to the same Base Salary or Bonus deferred for a given Plan Year or
Performance Period, the deferral election made closest in time to the last day the deferral of such Base Salary or Bonus may be elected under Section 3.01 or 3.02, as the case may be, shall control. 

 

	 	(c)	 If a Member ceases to be an Eligible Employee but continues to be employed by the Company, he or she shall
continue to be a Member and his or her Deferral Agreement(s) currently in effect shall be treated as follows: 


  

	 	(i)	 A Deferral Agreement for Base Salary for services performed in the Plan Year shall remain in force for the
remainder of such Plan Year. 


  

	 	(ii)	 A Deferral Agreement for Bonus for services performed in a Performance Period in which the Member ceases to be
an Eligible Employee shall remain in force for the remainder of such Performance Period. 



  
 5 













 The Member shall not be eligible to defer any portion of his or her Base Salary paid for
services performed in a subsequent Plan Year or Bonus for services performed in a subsequent Performance Period, until such time as he or she shall once again become an Eligible Employee and files a new Deferral Agreement with the Administrative
Committee in accordance with the provisions of Section 3.01 or 3.02, as applicable, and this Section 3.03. 
  

	 	(d)	 Notwithstanding anything in the Plan to the contrary, if an Eligible Employee receives a withdrawal of any pre-tax contributions on account of hardship from any plan maintained by the Company or an Affiliated Company and that meets the requirements of Code Section 401(k) (or any successor thereto) and is precluded
from making contributions to such 401(k) plan for at least six months after receipt of the hardship withdrawal (the “six-month Savings Plan suspension period”), the following provisions shall apply:



  

	 	(i)	 An election to defer Base Salary under his or her Deferral Agreement shall be cancelled during any six-month Savings Plan suspension period and no amount shall be deferred under this Plan under the Eligible Employee’s Deferral Agreement with respect to any Base Salary that is paid during a six-month Savings Plan suspension period. Any Base Salary payment that would have been deferred pursuant to a Deferral Agreement but for the application of this Section 3.03(d) shall be paid to the Eligible
Employee as if he or she had not entered into the Deferral Agreement. An Eligible Employee whose Base Salary deferral election under his or her Deferral Agreement is cancelled in accordance with the provisions of this Section 3.03(d)(i) may
elect to defer Base Salary for any Plan Year commencing after he or she is again permitted to contribute to such 401(k) plan by filing a new Deferral Agreement in accordance with the provisions of Section 3.01 or 3.02, as applicable, and this
Section 3.03. 


  

	 	(ii)	 An election to defer Bonus under his or her Deferral Agreement shall be cancelled during any six-month Savings Plan suspension period and no amount shall be deferred under this Plan under the Eligible Employee’s Deferral Agreement with respect to any Bonus that that is paid during a six-month Savings Plan suspension period. Any Bonus payment that would have been deferred pursuant to a Deferral Agreement but for the application of this Section 3.03(d)(ii) shall be paid to the Eligible
Employee as if he or she had not entered into the Deferral Agreement. An Eligible Employee whose Bonus deferral election under his or her Deferral Agreement is cancelled in accordance with the provisions of this Section 3.03(d)(ii) may elect to
defer Bonus for any Performance Period commencing after he or she is again permitted to contribute to such 40l (k) plan by filing a new Deferral Agreement in accordance with the provisions of Section 3.01 or 3.02, as applicable, and this
Section 3.03. 


  

	3.04	 Crediting to Account  



The amount of Base Salary or Bonus which an Eligible Employee has elected to defer shall be credited to his or her Deferral Account no later
than the first business day of the first calendar month following the date the Base Salary or Bonus would have been paid to the Eligible Employee in the absence of a Deferral Agreement with respect to such amount.

 ARTICLE 4. COMPANY ACCOUNT 

 

	4.01	 Amount of Company Contribution 



The Company intends to make Company 401(k) Restoration Matching Contributions to the Plan each year for each Member up to 5% of his or her
annual eligible compensation. The amount of such contribution shall be the difference between 
  

	 	(a)	 the Member’s “Safe Harbor Company Matching Contribution” under the Savings Plan; and



  

	 	(b)	 the matching contribution calculated as provided under the Savings Plan but based on the Member’s
Compensation (as defined in the Savings Plan) except without regard to the annual compensation limit under Code Section 401(a)(17) ($265,000 in 2015 and 2016) and including any deferrals made to this Plan. 



The amount of such Company 40l (k) Restoration Matching Contribution may be as much as 5% of the Member’s compensation (as determined
under subsection (b) above) and shall be contributed to this Plan and credited to the Member’s Company Account pursuant to Section 4.02. 

The rules described above are illustrated in the following example, which is based on total eligible compensation of $300,000, a $10,000
deferral into the Plan and an $18,000 elective deferral to the Savings Plan (the IRS limit for 2015 and 2016). In the example below, the Plan’s Company 401(k) Restoration Matching Contribution provides an additional $1,750 that could not be
made to the Savings Plan because of IRS compensation limits.

	 	(a)	 As of each Valuation Date, each Deferral Account (and any sub-account

return of one or more indices of investment performance, designated by the Administrative Committee and elected by the Member pursuant to Section 5.02 for purposes of measuring the investment performance of his or her Accounts.



  

	 	(b)	 The Administrative Committee shall designate at least one investment fund or index of investment performance
and may designate other investment funds or investment indices to be used to measure the investment performance of a Member’s Accounts. The designation of any such investment funds or indices shall not require the Company to invest or earmark
their general assets in any specific manner. The Administrative Committee may change the designation of investment funds or indices from time to time, in its sole discretion, and any such change shall not be deemed to be an amendment affecting
Member’s rights under Section 7.02. 


  

	5.02	 Investment Performance Elections  



In the event the Administrative Committee designates more than one investment fund or index of investment performance under Section 5.01,
each Member shall file an investment election with the Administrative Committee with respect to the investment of his or her Accounts within such time period and on such form as the Administrative Committee may prescribe. The election shall
designate the investment fund or funds or index or indices of investment performance which shall be used to measure the investment performance of the Member’s Accounts. The election shall be in increments of 1% or such other increments as the
Administrative Committee shall from time to time provide. In the event a Member does not file an investment election with the Administrative Committee within the time period prescribed, such Member’s Deferral Account and/or Company Account
shall be invested in the appropriate target date fund offered under the Plan based on the Member’s age and expected retirement date. 
  

	5.03	 Changing Investment Elections  



 

	 	(a)	 A Member may change his or her election of the investment fund or funds or index or indices of investment
performance used to measure the investment performance of his or her future amounts credited to his or her Deferral Account and Company Account on a daily basis in accordance with procedures prescribed by the Administrative Committee.



  

	 	(b)	 A Member may change his or her election of the investment fund or funds or index or indices of investment
performance used to measure the future investment performance of his or her existing Deferral Account and Company Account on a daily basis in accordance with procedures prescribed by the Administrative Committee. 



 

	5.04	 Individual Accounts  



The Administrative Committee shall maintain, or cause to be maintained, records showing the balances of each Member’s Deferral Account
(and any sub-account thereof) and Company Account. At least once a year, each Member shall be furnished with a statement setting forth the value of his or her Deferral Account and Company Account. 

  
 10 














	5.05	 Valuation of Accounts 



 

	 	(a)	 The Administrative Committee shall value or cause to be valued each Member’s accounts on each Valuation
Date and there shall be allocated to the accounts of each Member the appropriate amount determined in accordance with Section 5.01. 


  

	 	(b)	 Whenever an event requires a determination of the value of a Member’s Deferral Account (or any sub-account thereof) or his or her Company Account, the value shall be computed as of the Valuation Date coincident with, or immediately following, the date of the event. 



 

	 	(c)	 If a Member’s Deferral Account or Company Account (or any
sub-accounts thereof) are paid in installments pursuant to Section 6.01(b)(iii), such Member’s Deferral Account (or any sub-account thereof) shall continue to
be credited with earnings or losses as described in Section 5.01 during the installment payment period

 ARTICLE 6. PAYMENT OF BENEFITS

Deferral Account and Company Account (and any sub-accounts thereof) made either: 


  

	 	(i)	 In a lump sum payable as of the Member’s Termination of Employment or the first, second or third
anniversary of the Member’s Termination of Employment, as elected by the Member; or 


  

	 	(ii)	 In up to ten annual installments commencing upon the Member’s Termination of Employment or the first,

Plan Year 2017 deferral elections), that his or her Deferral Account and Company Account (and any sub-accounts thereof) be payable in a lump sum in a month and year elected by the Member at the time of the
deferral, which may be prior to such Member’s Termination of Employment, but which may be no earlier than the later of (A) the Plan Year in which such amounts were deferred or (B) the end of the Performance Period to which they apply;
provided that, should a Member elect payment under this Section 6.01(b), in the event such Member has a Termination of Employment prior to payment of his or her Accounts, such unpaid portion of his or her Accounts shall be paid pursuant to
Section 6.01(a) above or, in the event no election was made under 6.01(a), under Section 6.01(c) below. 


  

	 	(c)	 In the event the participant does not elect a time and form of payment and none of the alternative payment
provisions described in Sections 6.02 through 6.06 otherwise apply, distribution of the Member’s Deferral Account and Company Account (or any subaccounts thereof) shall be paid in a lump sum as soon as administratively feasible, but no later
than 90 days following a Member’s Termination of Employment. 


 All payment elections made under this
Section 6.01 must be made in a manner determined by the Administrative Committee and within the time frames specified in Section 3.01 (for contributions to a Member’s Deferral Account) and 4.04 (for contributions to a Member’s
Company Account). Deferral elections shall expire as of the last day of the Plan Year or Performance Period to which they apply. Accordingly, an Eligible Employee must make a separate election for each Plan Year and/or Performance Period, as
applicable. 
 Payment elections not made in compliance with Sections 3.01 or 4.04, as applicable, will be paid in the time and form
specified in Section 6.01 (c). 
  

	6.02	 Subsequent Deferral of Payment Date 



A Member may elect to have payment of his or her Accounts made or commenced no earlier than the fifth anniversary of the benefit commencement
date otherwise determined in accordance with Section 6.01 above. However, any election under this Section 6.02 shall be subject to the following: 

  
 12 














	 	(a)	 Any such election shall must be made at least 12 months prior to the Member’s Termination of Employment
with the Company and all Affiliated Companies; and 


  

	 	(b)	 Any such election shall not become effective until at least 12 months after the date on which the election is
made. 


 Once an election under this Section 6.02 becomes effective, it shall be irrevocable and the Member may not
make a subsequent election under this Section 6.02. 
  

	6.03	 Death Benefits  



If a Member dies before payment of his or her Deferral Account and Company Account commences or before the entire balance of his or her
Deferral Account is paid, an amount equal to the unpaid portion of his or her Deferral Account and of his or her Company Account shall be paid in a single cash lump sum to such Member’s Beneficiary as soon as administratively feasible but no
later than 90 days following the Member’s date of death. 
  

	6.04	 Payments to Specified Employees  



 

	 	(a)	 Notwithstanding any other provision of this Article 6 to the contrary, if the stock of the Company or any
Affiliated Company is publicly traded on an established securities market or otherwise and a Member who is a “specified employee” terminates his or her employment with the Company thereafter for reasons other than death, any payments due
during the first six months following the specified employee’s Termination of Employment shall be withheld by the Plan until the earlier of: 


  

	 	(i)	 the first day of the seventh month following the specified employee’s Termination of Employment with the
Company; or 


  

	 	(ii)	 his death. 



At that time, the withheld amounts shall be paid to the specified employee or, in the event of his or her death, to his or her Beneficiary.
The withheld amounts shall be credited with investment gains or losses or with interest during the period they are withheld. 
  

	 	(b)	 For purposes of this Section 6.04, a “specified employee” shall mean a Member who terminates
employment with the Company and who: 


  

	 	(i)	 met the requirements of Code Section 416 (i)(1)(A)(i), (ii) or (iii), applied in accordance with the
regulations thereunder and disregarding Code Section 416(i)(5), at any time during the 12-month period ending on the identification date; and 



 

	 	(ii)	 terminated his or her employment with the Company at any time during the
12-month period beginning on the April 1st next following the identification date. 



  
 13 













 For purposes of this Section 6.04, the definition of compensation under Treasury
Regulation §1.415(c)-2(a) shall be used when determining whether a Member meets the requirements of clause (i) above, applied without use of any safe harbor provided in Treasury Regulation §1.415(c)-2(d), any of the special timing rules provided in Treasury Regulation §1.415(c)-2(e) or any of the special rules in Treasury Regulation §1.415(c)-2(g) and the identification date shall be the December 31st immediately preceding the date the Participant terminates employment with the
Company. A Member who meets the requirements of clauses (i) and (ii) of this Section 6.04 shall be a specified employee regardless of whether the Member meets the requirements of clause (i) on the date he or she terminates his or her
employment with the Company. 
  

	6.05	 Unforeseeable Emergency 



 

	 	(a)	 While employed by the Company, a Member may, in the event of an unforeseeable emergency, request a withdrawal
from his or her Deferral Account. The request shall be made in a time and manner determined by the Administrative Committee, shall not be for a greater amount than the lesser of: 



 

	 	(i)	 the amount required to meet the unforeseeable emergency, including amounts necessary to pay any federal, state
or local income taxes; or 


  

	 	(ii)	 the amount of his or her Deferral Account, 



and shall be subject to approval by the Administrative Committee. 
  

	 	(b)	 For purposes of this Section 6.05, an unforeseeable emergency shall include a severe financial hardship to
the Member resulting from: 


  

	 	(i)	 sudden and unexpected illness of the Member, his or her spouse or his or her dependents (as defined in Code
Section 152 without regard to Code Sections l52 (b)(l), (b)(2) and (d)(l)(B)); 


  

	 	(ii)	 loss of the Member’s property due to a casualty, 



 

	 	(iii)	 other similar extraordinary circumstances arising as a result of events beyond the control of the Member
approved by the Administrative Committee if such circumstances would result in a present or impending critical financial need which the Member is unable to satisfy with funds reasonably available from other sources. 



 

	 	(c)	 Except as otherwise provided in Section 6.01(b)(ii) or this Section 6.05, a Member may not receive
any portion of his or her Deferral Account or Company Account prior to the Member’s Termination of Employment. 



  
 14 














	6.06	 Payment on Change in Control  



 

	 	(a)	 Notwithstanding the foregoing provisions of this Article 6, upon the occurrence of a “change in
control” (as defined in paragraph (b) below) a Member shall automatically become 100% vested in his or her Company Account and shall automatically receive the balance in his or her Deferral Account and in his or her Company Account in a
single lump sum cash payment. Such lump sum payment shall be made within 90 days after the change in control. If the Member dies after such change in control, but before receiving the payment, payment shall be made to his or her Beneficiary.



  

	 	(b)	 For purposes of this Section 6.06, a change in control shall mean 



 

	 	(i)	 a change in the ownership of Allegro MicroSystems, LLC as defined in Treasury Reg. 1.409A-3(i)(5)(v); 


  

	 	(ii)	 a change in the effective control of Allegro MicroSystems, LLC as defined in Treasury Reg. 1.409A-3(i)(5)(vi); or 


  

	 	(iii)	 a change in the ownership of a substantial portion of the assets of Allegro MicroSystems, LLC as defined in
Treasury Reg. l.409A-3(i)(5)(vii). 


  

	6.07	 Termination of Employment  



 

	 	(a)	 A Member shall have a termination of employment if the Member dies, retires or otherwise ceases to be an
employee of the Company. However, a Member will not be treated as retiring or terminating his or her employment with the Company for purposes of this Article 6 if: 



 

	 	(i)	 the Member is employed by an Affiliated Company; 



 

	 	(ii)	 the Member is on military leave, sick leave or other bona fide leave of absence if the period of such leave
does not exceed six months or, if longer, so long as the Member retains a right to reemployment with the Company or an Affiliated Company under an applicable statute or contract. If a Member’s leave exceeds six months and he or she does not
retain a right to reemployment under an applicable statute or contract, the Member is deemed to have terminated his or her employment with the Company on the first day following the end of the six-month
period; or 


  

	 	(iii)	 the Member continues to provide service to the Company in a capacity other than as an employee if the Member is
providing service at a level that is at least 50% of the average level of services performed by the Member during the immediately preceding 36-month period. 



 

	 	(b)	 A Member who continues to provide services to the Company shall nevertheless be treated as having terminated
his or her employment with the Company if the Member continues to provide service to the Company at a level that is 20% or less than the average level of services performed by the Member during the immediately preceding 36-month period. 



  
 15 














	 	(c)	 The provisions of this Section 6.07 shall be interpreted in a manner which complies with the requirements
of Code Section 409A. 


  

	6.08	 Designation of Beneficiary 



A Member may, in a time and manner determined by the Administrative Committee, designate a beneficiary and one or more contingent beneficiaries
(which may include the Member’s estate) as his or her Beneficiary under this Plan to receive any benefits which may be payable under this Plan upon his or her death. If the Member fails to designate a Beneficiary or contingent Beneficiary, or
if the Beneficiary and the contingent Beneficiaries fail to survive the Member, such benefits shall be paid to the Member’s estate. A Member may revoke or change any designation made under this Section 6.08 in a time and manner determined
by the Administrative Committee. 
  

	6.09	 Receipt and Release 



Any final payment or distribution to a Member or his or her Beneficiary or his or her legal representative shall be in full satisfaction of all
claims against the Plan, the Administrative Committee and the Company. The Administrative Committee may, in its sole discretion, require the Member or his or her Beneficiary or his or her legal representative to execute a receipt and release, in
such form as the Administrative Committee may determine, upon final payment of all claims under the Plan or distribution, or a receipt to the extent of any partial payment or distribution, as a condition of receiving such payment or distribution.
However, nothing in this Section 6.09 shall cause any required payment or distribution under the Plan to be made later than the last day permitted under Section 6.11. 

 

	6.10	 Delays in Payment 



Notwithstanding anything in this Article 6 to the contrary, payment of a Member’s benefit under the Plan may be delayed beyond the date it
would otherwise have been made under the terms of this Article 6 if the Company reasonably anticipates that making the payment will violate Federal securities laws or other applicable laws. In such an event, payment shall be delayed until the
earliest date the Company reasonably anticipates the payment will not cause such a violation. The inclusion of any amounts in gross income or the application of any penalty or other provision of the Code shall not be a violation for purposes of this
Section. 
  

	6.11	 Administrative Delay 



Payment of a Member’s benefit under the Plan shall be deemed to have commenced on a specified date if the payment commences as soon as
administratively practicable following such date, but no later than the later of: 
  

	 	(i)	 the last day of the Plan Year in which the specified date occurs; or 



 

	 	(ii)	 the 15th day of the third calendar month following the
month the specified date occurs.

the related Deferral Agreements at any time. In the event the Plan and related Deferral Agreements are terminated, the amounts in the Member’s Deferral Account and Company Account shall be paid to the Member in accordance with the provisions of
Article 6. Any action to terminate the Plan by the Manager shall be taken in such manner as may be permitted under the by-laws of the Company. 



 

	 	(a)	 If the Plan is terminated within 12 months of a corporate dissolution taxed under Code Section 331 or with
the approval of bankruptcy court pursuant to 11 U.S.C. 503(b)(l)(A), the Member’s Deferral Account and the vested portion of his or her Company Account will be paid in a lump sum on the first day of the first calendar month following such

	 	(a)	 Allegro MicroSystems, LLC may, by action of the Manager, in his or her sole discretion, amend this Plan and the
related Deferral Agreements in any way on 30 days prior notice to the Members. If any amendment to this Plan or to the Deferral Agreements shall adversely affect the rights of a Member, such individual must consent in writing to such amendment prior
to its effective date. If such individual does not consent to the amendment, the Plan and related Deferral Agreements shall be deemed to be terminated with respect to such individual. Notwithstanding the foregoing, the Administrative
Committee’s change in any investment funds or investment index under Section 5.01, or the restriction of future Bonuses (and the opportunity to defer Bonuses) shall not be deemed to adversely affect any Member’s rights. Any action to
amend the Plan by the Manager shall be taken in such manner as may be permitted under the by-laws of the Company. 


  

	 	(b)	 Notwithstanding anything in Section 7.02(a) to the contrary, the Administrative Committee may amend the
Plan at any time and from time to time, as it deems necessary, in order to comply with the provisions of Code Section 409A or any other applicable statute. 



 

	7.03	 Uniform Action

uniform and nondiscriminatory manner.

 ARTICLE 8. GENERAL PROVISIONS 

 

	8.01	 Funding 



 

	 	(a)	 All amounts payable in accordance with this Plan shall constitute a general unsecured obligation of the
Company. Such amounts, as well as any administrative costs relating to the Plan, shall be paid out of the general assets of the Company, to the extent not paid by a grantor trust established pursuant to paragraph (b) below.



  

	 	(b)	 The Company may, for administrative reasons, establish a grantor trust for the benefit of Members participating
in the Plan. The assets of said trust will be held separate and apart from other Company funds, and shall be used exclusively for the purposes set forth in the Plan and the applicable trust agreement, subject to the following conditions:



  

	 	(i)	 the creation of said trust shall not cause the Plan to be other than “unfunded” for purposes of Title
I of the Employee Retirement Income Security Act of 1974; 


  

	 	(ii)	 the Company shall be treated as “grantor” of said trust for purposes of Code Section 677; and



  

	 	(iii)	 said trust agreement shall provide that its assets may be used to satisfy claims of the Company’s general
creditors, and the rights of such general creditors are enforceable by them under federal and state law. 


  

	8.02	 No Contract of Employment 



The existence of this Plan or of a Deferral Agreement does not constitute a contract for continued employment between an Eligible Employee or a
Member and the Company. Except as otherwise limited by the terms of any valid employment contract or agreement entered into between the Company and an Eligible Employee or Member, the Company reserve the right to modify an Eligible Employee’s
or Member’s remuneration and to terminate an Eligible Employee or a Member for any reason and at any time, notwithstanding the existence of this Plan or of a Deferral Agreement. 

 

	8.03	 Withholding Taxes 



All payments under this Plan shall be net of an amount sufficient to satisfy any federal, state or local withholding tax requirements. 

 

	8.04	 Nonalienation 



Subject to applicable law, the right to receive any benefit under this Plan may not be transferred, assigned, pledged or encumbered by a

 18 














	 	(b)	 Prior to paying any benefit under this Plan, the Administrative Committee may require the Member, Beneficiary
or contingent Beneficiary to provide such information or material as the Administrative Committee, in its sole discretion, shall deem necessary for it to make any determination it may be required to make under this Plan. The Administrative Committee
may withhold payment of any benefit under this Plan until it receives all such information and material and is reasonably satisfied of its correctness and genuineness, provided, however, that payment shall not be withheld beyond the date specified
under Section 6.11.

claim for benefits under this Plan has been denied, setting forth the specific reasons for such denial. A reasonable opportunity shall be afforded to any such Member, former Member, Beneficiary or contingent Beneficiary for a full and fair review by
the Administrative Committee of its decision denying the claim. The Administrative Committee’s decision on any such review shall be final and binding on the Member, former Member, Beneficiary or contingent Beneficiary and all other interested
persons. 
  

	8.07	 Facility of Payment  



In the event the Administrative Committee shall find that a Member or his or her Beneficiary is unable to care for his or her affairs because
of illness or accident, the Administrative Committee may direct that any benefit payment due, unless claim shall have been made therefore by a duly appointed legal representative, be paid to such Member’s spouse, child, parent or other blood
relative, or to a person with whom the Member resides, and any such payment so made shall be a complete discharge of the liabilities of the Plan therefore. 
  

	8.08	 Limitation of Liability  



The Company, the members of the Administrative Committee, and any officer, employee or agent of the Company shall not incur any liability
individually or on behalf of any other individuals or on behalf of the Company for any act or failure to act, made in good faith in relation to the Plan.

applicable law, be indemnified against any and all liabilities arising by reason of any act, or failure to act, in relation to the Plan including, without limitation, expenses reasonably incurred in the defense of any claim relating to the Plan,
amounts paid in any compromise or settlement relating to the Plan and any civil penalty or excise tax imposed by any applicable statute, if:

 This determination shall be made by the Company and, if such determination is made in good faith and not arbitrarily or
capriciously, shall be conclusive.

obligation hereunder shall be offset to the extent of any otherwise applicable insurance coverage under a policy maintained by the Company or any other person, or other source of indemnification.
