INTRODUCTION


The Tax Deferred Compensation Savings Plan (“Plan”) was originally established, effective January 1, 1984, by the Board of Directors of MDU Resources Group, Inc. (formerly known as Montana-Dakota Utilities Co.) for the exclusive benefit of its employees.  It is intended to provide a means for deferred savings and investment by employees and to afford security for their retirement. The Company will make contributions, as provided herein, to be added to such savings.


The Plan is intended to comply with the requirements of the Employee Retirement Income Security Act of 1974 and Section 401(k) of the Internal Revenue Code of 1986, as amended, and the Regulations promulgated thereunder.  Effective as of January 1, 1988, the Plan was amended and restated to reflect the merger, also effective as of that date, of the Plan with the Employee Stock Ownership Plan for which contributions were suspended.  Effective as of October 1, 1990, the Plan was amended and restated to provide additional investment options.  Certain officers, as set forth in Section 16 of the Securities Exchange Act of 1934 and the rules thereunder (“Section 16 Officer(s)”), are subject to special limitations on their ability to make “participant-directed transactions” under the Plan.  These provisions are set forth in Section XII of the Plan and apply to Section 16 Officers notwithstanding any other inconsistent provisions in the Plan. Effective January 1, 1994, the Plan was amended and restated to provide, among other things rollovers into the Plan from qualified sources, and provide the Committee with authority to extend participation rights. Effective April 1, 1994, the Plan was amended to provide increased ability to change investment elections.


Effective January 1, 1995, the Anchorage Sand and Gravel Company, Inc. Profit Sharing/401(k) Plan was merged with the Plan.

Effective January 1, 1997, the Plan was amended to provide, among other things:  daily fund transfers and investment election changes by participants, as well as other changes resulting from a conversion to daily recordkeeping.


Effective January 1, 1998, the Plan was amended and restated to provide, among other things: participant loans.


Effective January 1, 1999, the Plan was amended to provide, among other things: a variable match and profit sharing feature.  Also effective January 1, 1999, the MDU Resources Group, Inc. Tax Deferred Compensation Savings Plan for Collective Bargaining Unit Employees was merged into this Plan, and the Plan was renamed the MDU Resources Group, Inc. 401(k) Retirement Plan.


Effective December 1, 1999, the Plan was amended to allow participating employers the flexibility to provide their Participants with different maximum deferral levels.


Effective April 1, 2000, the LTM, Incorporated 401(k) Employee Savings Plan was merged with the Plan.


Effective February 15, 2001, the Plan was amended to allow matching contributions to be diversified.


Effective January 1, 2003, the Plan was amended to include a Davis-Bacon feature.


Effective August 1. 2005, the Plan was amended to change the form of matching contributions from Common Stock to cash and to allow after-tax employee rollovers.


Effective as of May 25, 2006, the Plan was amended to expand the portion of the Plan intended to qualify as an employee stock ownership plan under Section 4975(e)((7) of the Code.  On and after June 1, 2006, a portion of the Plan is designed to invest primarily in Common Stock, and is intended to satisfy the requirements of a non-leveraged employee stock ownership plan set forth in Sections 401(a), 409, and 4975(e) of the Internal Revenue Code (the “ESOP”).  The remaining portion of the Plan shall consist of all amounts credited to Participants’ Accounts

that are invested in Common Stock.  The Non-ESOP portion of the Plan shall consist of all amounts credited to Participants’ Accounts that are not invested in Common Stock.  The Committee shall maintain such Accounts and subaccounts as are deemed necessary for appropriate to reflect the value of Participants’ Accounts in the ESOP portion of the Plan and the Non-ESOP portion of the Plan.  Effective January 1, 2010, the Plan was amended to provide Retirement Contributions to those employees who were Participants in the MDU Resources Group, Inc. Pension Plan for Non-Bargaining Unit Employees, the Knife River Corporation Salaried Employees’ Pension Plan, and the Williston Basin Interstate Pipeline Company Pension Plan, for which future benefits accruals ended as of December 31, 2009.

The Actual Deferral Percentage for any Plan Year beginning on or after January 1, 1987 of all Eligible Employees who are Highly Compensated Employees shall















  





- 20 -











  


















not exceed, alternatively: (I) 125 percent of the Actual Deferral Percentage for all Eligible Employees who are not Highly Compensated Employees, or (II) 200 percent of the Actual Deferral Percentage for Eligible Employees who are not Highly Compensated Employees, provided that the Actual Deferral Percentage for all Highly Compensated Employees does not exceed the Actual Deferral Percentage for all other Eligible Employees by more than 2 percentage points.



	
  

	
(c)

	
For purposes of this Section 3.5, the Actual Deferral Percentage for a Plan Year shall be the average of the ratios, calculated separately for each Eligible Employee in each group, of the amount of savings contributions credited to the Savings Contribution Account on behalf of each Eligible Employee for such Plan Year to the Eligible Employee’s Section 415 Compensation (as defined in Section 3.7) for such Plan Year.








	
  

	
(d)

	
If a reduction in the amount of savings contributions on behalf of a Participant is required because of the application of (a) above, the reduction shall be treated as taxable earnings to the Participant for the pay period in which the reduction occurs, and the Employer shall withhold any taxes required by law on such taxable earnings.








	
  

	
(e)

	
If a distribution of excess deferral contributions (and related earnings) is required because of the application of (a) above, the Employer shall withhold any taxes required by law on such distribution.








	
  

	
(f)

	
In the event an active Participant is required to reduce savings contributions to the Plan as a result of the application of the provisions of (a) above, the matching contribution under Section 3.3 made on behalf of the Participant for the remainder of the Plan Year shall be applied to the reduced amount of savings contributions.















  





- 21 -











  



















	
  

	
(g)

	
Notwithstanding the foregoing provisions of this Section 3.5, the maximum amount of savings contributions credited to the Savings Contribution Account on behalf of a Participant in any calendar year may not exceed $11,000, as may be adjusted in accordance with regulations prescribed by the Secretary of the Treasury to reflect increases in the cost of living, and any such contributions made to the Savings Contribution Account in excess of such $11,000 amount (as adjusted), plus any related earnings on such excess amount, shall be distributed to the Participant no later than April 15 following the close of the calendar year in which such excess contributions are made. The amount of savings contributions distributed to a Participant pursuant to the immediately preceding sentence shall be reduced by the amount of savings contributions distributed to such Participant pursuant to paragraph (a) above for the same Plan Year.







Savings contributions exceeding the limits of this paragraph (g) shall mean the amount of savings contributions (as defined in Section 3.1) for a calendar year that the Participant designates to the Plan pursuant to the following procedure.  The Participant’s designation shall (1) be submitted to the administrator in writing no later than March 1, (2) specify the Participant’s savings contributions exceeding the limits of this paragraph (g) for the preceding calendar year, and (3) be accompanied by the Participant’s written statement that if such excess savings contribution is not distributed, it will, when added to amounts deferred under other plans or arrangements described in Section 401(k), 408(k), or 403(b) of the Code, exceed the limit imposed on the Participant by Section 402(g) of the Code for the year in which the deferral occurred. Savings contributions exceeding the limits of this paragraph (g) shall mean those savings contributions that are includible in a Participant’s gross income under Section










  





- 22 -











  


















402(g) of the Code to the extent that such Participant’s savings contributions for a taxable year exceed the dollar limitation under such Code section.  Such excess savings contributions, and the income or loss allocable thereto, may be distributed before the end of the calendar year in which the savings contributions were made. A Participant who has such excess savings contributions for a taxable year, taking into account only such savings contributions under the Plan or any other plan of the Employer (including any member of the Employer’s related group), shall be deemed to have designated the entire amount of such excess savings contributions.



	
  

	
(h)

	
The earnings allocable to distributions of savings contributions exceeding the limits of paragraph (b) or (g) shall be the sum of: (i) the earnings attributable to the Participant’s savings contributions for the year multiplied by a fraction, the numerator of which is the applicable excess amount, and the denominator of which is the balance in the Savings Contribution Account of the Participant on the last day of such year reduced by gains (or increased by losses) attributable to such account for the year; and (ii) ten percent (10%) of the amount determined under (i) multiplied by the number of whole calendar months between the end of the Plan Year and the date of distribution, counting the month of distribution if distribution occurs after the fifteenth (15th) of such month.








	
  

	
(i)

	
All employees who are eligible to make savings contributions under the Plan and who have attained age 50 before the close of the Plan Year shall be eligible to make catch-up contributions in accordance with, and subject to the limitations of, Section 414(v) of the Code, effective for contributions made after December 31, 2001. Such catch-up contributions shall not be taken into account for purposes of implementing the required limitations of Sections 402(g) and 415 of the Code.















  





- 23 -











  


















The Plan shall not be treated as failing to satisfy the requirements of Sections 401(k)(3), 401(k)(11), 401(k)(12), 410(b), or 416 of the Code, as applicable, by reason of the making of such catch up contributions.



	
3.6

	
Special Matching Contribution Limitations








	
  

	
(a)

	
For each Plan Year, the Plan shall comply with Code Section 401(m)(2). Specifically, if the Contribution Percentage (as defined in paragraph (c) below) for Participants who are Highly Compensated Employees is more than the amount permitted under the special limitations set forth under paragraph (b) of this Section 3.6, the Employer matching contributions credited to the Matching Contribution Accounts of those Participants who are Highly Compensated Employees shall be reduced (in the order of the Highly compensated Employees with the highest dollar amount of matching contribution) to the extent necessary to meet the requirements of paragraph (b) below. Any excess matching contributions made to the Trust Fund, plus any related earnings thereof, shall be distributed to such Participants before the end of the Plan Year following the Plan Year in which such excess matching contributions are made. The earnings allocable to distributions of savings contributions exceeding the limits of paragraph (b) or (g) shall be the sum of:  (i) the earnings attributable to the Participant’s savings contributions for the year multiplied by a fraction, the numerator of which is the applicable excess amount, and the denominator of which is the balance in the Savings Contribution Account of the Participant on the last day of such year reduced by gains (or increased by losses) attributable to such account for the year; and (ii) ten percent (10%) of the amount determined under (i) multiplied by the number of whole calendar months between the end of the Plan Year and the date of distribution, counting the month of distribution if















  





- 24 -











  


















distribution occurs after the fifteenth (15th) of such month.  In addition, if the Employer or the Committee determines that contributions or matching contributions would be in excess of the special limitations set forth under paragraph (b) below, the Employer may, in its sole discretion, suspend, in whole or in part, savings contributions to the Plan made on behalf of Participants who are Highly Compensated Employees and, therefore, related matching contributions with respect to such Participants in which case the savings contributions that would ordinarily be contributed to the Trust Fund on the Participants’ behalf in a payroll period shall be paid directly to such Participants.



	
  

	
(b)

	
The Contribution Percentage for any Plan Year of all Eligible Employees who are Highly Compensated Employees shall not exceed, alternatively: (A) 125 percent of the Contribution Percentage for all Eligible Employees who are not Highly Compensated Employees, or (B) 200 percent of the Contribution Percentage for Eligible Employees who are not Highly Compensated Employees, provided that the Contribution Percentage for all Highly Compensated Employees does not exceed the Contribution Percentage for all other Eligible Employees by more than 2 percentage points.








	
  

	
(c)

	
For purposes of this Section 3.6, the Contribution Percentage for a Plan Year shall be the average of the ratios, calculated separately for each Eligible Employee in each group, of the amount of matching contributions to the Matching Contribution Account on behalf of each Eligible Employee for such Plan Year to the Eligible Employee's Section 415 Compensation (as defined in Section 3.7) for such Plan Year.








	
  

	
(d)

	
If a reduction in the amount of savings contributions on behalf of a Participant is required because of the application of paragraph (a) above, the reduction shall















  





- 25 -











  


















be treated as taxable earnings to the Participant for the pay period in which the reduction occurs, and the Employer shall withhold any taxes required by law on such taxable earnings.



	
  

	
(e)

	
If a distribution of excess savings contributions or excess matching contributions (and related earnings) is required because of the application of a) above, the Employer shall withhold any taxes required by law on such distribution.








	
  

	
(f)

	
In the event an active Participant is required to reduce savings contributions to the Plan as a result of the application of the provisions of paragraph (a) above, the matching contribution under Section 3.3 made on behalf of the Participant for the remainder of the Plan Year shall be applied to the reduced amount of savings contributions.








	
3.7

	
Contribution Limitation.  Notwithstanding any provision of the Plan to the contrary, and except to the extent permitted under Section 414(v) of the Code, the “annual additions” (as defined below) to a Participant’s Accounts shall not exceed the lesser of (a) 100 percent of the Participant’s total “Section 415 compensation” (as defined below) or (b) $46,000, as adjusted for cost-of-living increases under Section 415(d) of the Code.  Plan benefits shall be paid in accordance with Section 415 of the Code and applicable Treasury Regulations issued thereunder, the requirements of which are incorporated herein by reference to the extent not specifically provided herein.







The term “annual addition” for any Plan Year means the sum of (a) the savings contributions, matching contributions and profit sharing contributions, if any, credited to a Participant’s Accounts for that year, and (b) the contributions made by an Employer or Affiliate on behalf of such Participant (including contributions made by such Participant pursuant to an election to defer earnings), and any remainders to be credited to his account under any other defined contribution plan maintained by the Employers or










  





- 26 -











  


















Affiliates in which such employee participates.  The Plan Administrator shall take any actions it deems advisable to avoid an annual addition in excess of the limitations set forth in Section 415 of the Code; provided, however, if a Participant’s annual addition for a Plan Year actually exceeds the limitations of this subsection 3.7, the Plan Administrator shall correct such excess in accordance with applicable Treasury Regulations or applicable guidance issued by the Internal Revenue Service.


The term “Section 415 compensation” shall mean the total of all of the wages, salaries and other amounts received by the Participant from an Employer or Affiliate for services rendered to an Employer or Affiliate as reflected on Form W-2, but only to the extent such amounts are includible as compensation under Section 415(c)(3) of the Code and the regulations thereunder (including any amounts includible in a Participant’s income under the rules of Section 409A of the Code or because the amounts are constructively received by the Participant for any year beginning on or after January 1, 2008) and any differential wage payment (as defined in Section 3401(h) of the Code), plus (a) any elective deferrals (as defined in Section 402(g)(3) of the Code) and (b) any amount contributed or deferred by an Employer at the Participant’s election which is excludable from income under Sections 125, 132(f)(4) or 457 of the Code.


Notwithstanding the foregoing, Section 415 compensation for a Plan Year shall include compensation paid to the Participant by the later of 2-1⁄2 months after the Participant’s severance from employment with an Employer or the end of the Plan Year that includes the date of the Participant’s severance from employment with such Employer if: (i) the payment is regular compensation for services during the Participant’s regular working hours, or compensation for services outside the Participant’s regular working hours (such as overtime or shift differential), commissions, bonuses, or other similar payments, and, absent a severance from employment, the payments would have










  





- 27 -











  


















been paid to the Participant while the Participant continued in employment with an Employer; (ii) the payment is for unused accrued bona fide vacation time that the Participant would have been able to use if employment had continued; or (iii) the payment is received by the Participant pursuant to a nonqualified unfunded deferred compensation plan, but only if the payment would have been paid at the same time if employment had continued and only to the extent the payment is includible in gross income. Payments other than those described above shall not be considered compensation if paid after severance from employment, even if they are paid by the later of 21⁄2 months after the date of severance from employment or the end of the Plan Year that includes the date of severance from employment, except: (i) payments to an individual who does not currently perform services for an Employer by reason of qualified military service (within the meaning of Section 414(u)(1) of the Code) to the extent these payments do not exceed the amounts the individual would have received if the individual had continued to perform services for the Employer rather than entering qualified military service; or (ii) compensation paid to a Participant who is permanently and totally disabled, as defined in Section 22(e)(3) of the Code, provided that either salary continuation applies to all Participants who are permanently and totally disabled for a fixed or determinable period, or the Participant was not a highly compensated employee immediately before becoming disabled.  Notwithstanding any provision of the Plan to the contrary, Section 415 compensation shall not include amounts in excess of the limitation under Section 401(a)(17) of the Code in effect for the Plan Year.



	
3.8

	
Rollover Contributions.  At the direction of the Committee, and in accordance with such uniform rules as the Committee may from time to time establish, rollovers described in Section 402(c) of the Code, rollovers from an annuity contract described in Section 403(b) of the Code, rollovers from an eligible plan under Section 457(b) of the Code that















  





- 28 -











  


















is maintained by a state, political subdivision of a state, or any agency or instrumentality of a state or political subdivision of a state and that is not tax-exempt, and rollovers from an Eligible Employee under another plan which meets the requirements of Section 401(a) of the Code, including after-tax employee contributions, may be received by the Trustee and will be credited to an Account established in the name of the Eligible Employee. Any rollover contribution made in accordance with the preceding sentence must be made in cash; rollover contributions of property other than cash will not be accepted.  Any amount received by the Trustee for an Eligible Employee in accordance with this Section 3.8 shall be adjusted during each accounting period for their pro rata share of any change in the value of the Investment Funds.  Eligible Employees shall be fully vested in their Rollover Account.

ARTICLE IV


ACCOUNTS; VESTING; DISTRIBUTIONS



	
4.1

	
Participants’ Accounts








	
  

	
(a)

	
The Employer shall maintain, or cause to be maintained, records which reflect the interest of each Participant’s Savings Contribution Account, Matching Contribution Account, ESOP Account, Rollover Account, and Profit Sharing Account, as applicable, including all contributions, income, gains or losses, and withdrawals with respect to such Accounts. Records for the Participants’ Accounts shall be maintained in accordance with procedural rules as determined by the Committee.  As of such valuation dates as the Committee shall determine, but not less frequently than once each Plan Year, the Committee shall determine the value of each Participant’s Accounts.








	
  

	
(b)

	
At least once each Plan Year, the Employer shall cause to be furnished to each Participant a statement of the contributions made by the Employer on the Participant’s behalf, and the value of the Participant’s Accounts, as well as such information as may be necessary to set forth earnings, gains, or losses with respect to the Participant’s Accounts.








	
4.2

	
Vesting








	
  

	
(a)

	
A Participant will, at all times, have a fully vested and nonforfeitable right to the value of the Participant’s Savings Contribution Account, Matching Contribution Account, Rollover Account, and ESOP Account. As described  in any Plan  supplement  adding a  Profit Sharing feature, a number of years of service may be required for the Participant to be fully vested in their Profit Sharing Account.  If a Participant terminates employment before becoming fully or partially vested in their Profit







 










  





- 30 -











  


















Sharing Account, the non-vested portion in such account shall be forfeited as of the last day of the Plan Year in which the Participant terminates employment with the Company and all Affiliates. Any forfeitures which arise under the terms of this paragraph shall be used for any of the following: 1) to reinstate the profit sharing contributions of any reemployed Participants pursuant to the terms of the Plan, 2) to reduce profit sharing contributions to the Plan, and 3) to reduce administrative expenses incurred by the Plan.  In the case of a Profit Sharing Feature or Retirement Contribution Feature requiring a number of years of service for the Participant to be fully vested in his or her Profit Sharing/Retirement Contribution Account, a Participant who dies while performing qualified military service (as defined in Section 414(u) of the Code) will receive service credit for vesting purposes for the period of qualified military service.


 



	
  

	
(b)

	
If a Participant’s employment with the Company and all Affiliates terminates before becoming vested in their Profit Sharing Account, and such Participant is subsequently reemployed by the Company or an Affiliate, the following special rules shall apply:








	
  

	
(i)

	
A “1-Year Break In Service” means a Plan Year in which a terminated Participant completes less than 500 Hours of Service.








	
  

	
(ii)

	
If the Participant was not vested at his or her prior termination of employment, the Participant’s years of vesting service prior to the termination of employment shall be aggregated with years of vesting service accrued upon reemployment only if number of their consecutive 1-Year Breaks in Service is less than five (5).















  





- 31 -











  



















	
  

	
(iii)

	
In the case of a Maternity or Paternity Absence (as defined below), a Participant shall be credited, for the first Plan Year in which they otherwise would have incurred a 1-Year Break In Service (and solely for purposes of determining whether such a Break In Service has occurred), with the Hours of Service which normally would have been credited to the Participant but for such absence (or, if the Committee is unable to determine the hours which would have been so credited, 8 hours for each work day of such absence), but in no event more than 501 hours for any one absence.  A “Maternity or Paternity Absence” means an Employee’s absence from work because of the pregnancy of the Employee or birth of a child of the Employee, the placement of a child with the Employee in connection with the adoption of such child by the Employee, or for purposes of caring for the child immediately following such birth or placement. The Committee may require the Employee to furnish such information as the Committee considers necessary to establish that the Employee’s absence was for one of the reasons specified above.








	
  

	
(iv)

	
If a Participant terminated employment with the Company and all Affiliates before the Participant was fully vested in the Participant’s Profit Sharing Account, and is reemployed by the Company or an Affiliate before incurring five (5) consecutive 1-Year Breaks In Service, the forfeiture which resulted from their earlier termination of employment (unadjusted by subsequent gains or losses if the Participant received a prior distribution from the Plan) shall be recredited to the Participant’s Profit Sharing Account as of the accounting date coincident with or next following the date of their reemployment.















  





- 32 -











  



















	
4.3

	
Distribution








	
  

	
(a)

	
The amount credited to a Participant’s Accounts, to the extent such Participant is vested in such Accounts, shall become payable to the Participant (or the beneficiary, as applicable) subject to Section 4.6 upon any of the following events:








	
  

	
(i)

	
Retirement;








	
  

	
(ii)

	
Disability;








	
  

	
(iii)

	
Death;








	
  

	
(iv)

	
Other termination of employment with the Employer;








	
  

	
(v)

	
As a hardship withdrawal under Section 4.5(a);








	
  

	
(vi)

	
As a withdrawal after age 59 1/2 pursuant to Section 4.5(b).








	
4.4

	
Method of Payment. Participants (or their beneficiaries), in accordance with such uniform rules as the Committee may establish, shall elect distribution of their Accounts in one of the following methods:








	
  

	
(a)

	
as a single sum distribution; or








	
  

	
(b)

	
in annual installments over a period of time, not to exceed five (5) years.







Distributions shall generally be paid in cash; provided, however, that distributions from a Participant’s ESOP Account may, at the Participant’s election, be paid in the form of Common Stock.



	
4.5

	
Withdrawals by Participants








	
  

	
(a)

	
Hardship Withdrawal.  A Participant may apply for a hardship withdrawal at any time. The withdrawal must be for an immediate and heavy financial need of the Participant for which funds are not reasonably available from other resources of the Participant.  If approved, such withdrawal shall equal the lesser of: 1) the amount required to be distributed to meet the need created by the hardship,















  





- 33 -











  


















(including any amounts necessary to pay any federal, state, or local income taxes or penalties reasonably anticipated to result from the withdrawal), or 2) the value of the Participant’s Savings Contribution Account (excluding earnings credited to such Account after December 31, 1988), Matching Contribution Account, ESOP Account, Rollover Account, and vested portion of the Profit Sharing Account.  Immediate and heavy financial needs are limited to amounts necessary for:



	
  

	
(i)

	
Unreimbursed medical expenses (as defined in Section 213 of the Code, determined without regard to whether the expense exceeds 71⁄2% of adjusted gross income) incurred by the Participant, the Participant’s spouse, or the Participants “dependents” (as defined in Section 152 of the Code without regard to Sections 152(b)(1), (b)(2),    and (d)(1)(B)).








	
  

	
(ii)

	
Preventing foreclosure on or eviction from the Participant’s principal residence.








	
  

	
(iii)

	
Costs directly related to the purchase of the Participant’s principal residence, not including mortgage payments.








	
  

	
(iv)

	
Tuition, room and board, and related educational fees for the next 12 months of post-secondary education for the Participant or the Participant’s spouse, children, or dependents.








	
  

	
(v)

	
Funeral or burial expenses for the Participant’s deceased parent, spouse, children or dependents.








	
  

	
(vi)

	
Expenses for repair of damages to the Participant’s principal residence that would qualify for a casualty loss deduction under Section 165 of the Code (determined without regard to whether the loss exceeds ten percent (10%) of adjusted gross income).















  





- 34 -











  


















If a hardship withdrawal is granted under this Section 4.5(a), the Participant must suspend making savings contributions and contributions to any other qualified or nonqualified plans of deferred compensation maintained by the Company for a minimum period of six months after the hardship distribution is received; such suspension does not include contributions to a health or welfare benefit plan including one that is part of a cafeteria plan within the meaning of Section 125 of the Code.  A hardship withdrawal shall be paid to the Participant in cash as soon as practicable after approval of the Participant’s written request.


A hardship withdrawal may be made only after the Participant has obtained all distributions, other than hardship withdrawals (including distributions of ESOP dividends under Section 404(k) of the Code) and all nontaxable loans currently available under all qualified plans (and any other employee benefit plan specified in Internal Revenue Service rules and regulations applicable to such hardship withdrawals) maintained by the Company or an Affiliate including this Plan.



	
  

	
(b)

	
Withdrawal After Age 59-1/2.  A Participant who has attained age 59-1/2 may withdraw, by written election to the Committee once per Plan Year, all or any portion of the Participant’s Savings Contributions Account, Matching Contribution Account, ESOP Account, Rollover Account, and vested portion of the Profit Sharing Account, in cash or in the form of Common Stock.








	
  

	
(c)

	
Rollover Withdrawal.  A Participant may withdraw, at any time by written election, all or any portion of the Participant’s Rollover Account.








	
4.6

	
Timing of Distributions








	
  

	
(a)

	
When Distributions May Commence.  If a Participant has incurred a distribution event described in Section 4.3 and requests a distribution of the Account, amounts credited to such Participant’s Accounts will be paid as soon as















  





- 35 -











  


















practicable after such amounts are ascertained. In accordance with Section 414(u)(12) of the Code, a Participant receiving a differential wage payment (as defined in Section 3401(h)(2) of the Code) shall be treated as having been severed from employment with the Employers and Affiliates for purposes of taking a distribution of his or her Account during any period the Participant performs service in the uniformed services while on active duty for a period of more than 30 days.  If a Participant elects to receive a distribution pursuant to the preceding sentence, such Participant shall not be permitted to make Savings Contributions under Section 3.1 of the Plan during the six-month period beginning on the date of the distribution.



	
  

	
(b)

	
When Distributions Must Commence








	
  

	
(i)

	
Accounts Not Exceeding $1,000. If a Participant incurs a distribution event described in Section 4.3(a) (i)-(iv) and the value of the Account (excluding any loan offset amount) does not then exceed $1,000, such Account shall be distributed as soon as practicable after such amounts are ascertained without the need for the Participant’s consent to such distribution.








	
  

	
(ii)

	
Accounts in Excess of $1,000.  If a Participant incurs a distribution event described in Section 4.3(a) (i)-(iv) payment of a Participant’s Accounts shall commence not later than the 60th day after the end of the calendar year in which the latest of the following events occurs:








	
  

	
(A)

	
the Participant attains age 62;








	
  

	
(B)

	
the tenth anniversary of the year in which the Participant commenced participation in the Plan occurs; or















  





- 36 -











  



















	
  

	
(C)

	
the Participant terminates employment with the Company and all Affiliates;







provided, however, that the Participant may elect to defer distribution of the Accounts (by not requesting a distribution) until attainment of age 70-1/2.  As a result, if the Participant’s Account (excluding the balance in the Participant’s Rollover Account and any loan offset amount) exceeds $1,000, a distribution will not be made to the Participant before attainment of age 70-1/2 without consent.  Upon a Participant’s attainment of age 70-1/2, distribution of the Account shall commence as soon as practicable after such amounts are ascertained.  If a Participant dies before age 70-1/2 and the Participant’s surviving spouse is the beneficiary, the surviving spouse may elect to defer distribution of the Participant’s Account until the Participant would have attained age 70-1/2.



	
  

	
(c)

	
Minimum Distribution Rules for Employees Who Continue in Service After Attaining Age 70-1/2. All distributions under the Plan shall be made in accordance with Code Section 401(a)(9) and the regulations promulgated thereunder.








	
  

	
(i)

	
5% Owners in Service After Attaining Age 70-1/2  With regard to a Participant who is a 5% owner (as defined in Code Section 416), payment of a benefit under the Plan shall commence no later than the April 1 next following the calendar year in which such Participant attains age 70-1/2, regardless of whether the Participant has retired or otherwise terminated employment as of such date.








	
  

	
(ii)

	
All Other Participants in Service After Attaining Age 70-1/2  With regard to Participants other than 5% owners who continue to be an active















  





- 37 -











  


















employee after attaining age 70-1/2, distribution of their Accounts is not required until they terminate employment.



	
4.7

	
Distributions Made in Accordance with Code Section 401(A)(31).  This Section applies to distributions made on or after January 1, 1993.  Notwithstanding any provision of the Plan to the contrary that would otherwise limit a Distributees election under this Section, a Distributee may elect, at the time and in the manner prescribed by the Plan Administrator, to have any portion of an Eligible Rollover Distribution paid directly to an Eligible Retirement Plan specified by the Distributee in a Direct Rollover.  With respect to any portion of a distribution from the Plan on behalf of a deceased Participant made on or after January 1 2007, if a direct trustee-to-trustee transfer is made to an individual retirement plan described in Section 408(a) or (b) of the Code (an “IRA”), which IRA is established for the purpose of receiving the distribution on behalf of an individual who is a designated beneficiary (as defined by Section 401 (a)(9)(E) of the Code) of the Participant and who is not the surviving spouse of the Participant, then the transfer shall be treated as an eligible rollover distribution for purposes of this Plan and Section 402(c) of the Code. For purposes of this subsection, the IRA of the non-spouse) beneficiary is treated as an inherited IRA within the meaning of Section 408(d)(3)(C) of the Code. The Plan may make a direct rollover to an IRA on behalf of a trust where the trust is the designated beneficiary of a Participant, provided (1) the beneficiaries of the trust meet the requirements of a designated beneficiary described above; (2) the IRA is established in accordance with Internal Revenue Service guidance, with the trust identified as the beneficiary; and (3) the trust meets the requirements set forth in Treasury Regulation Section 1.401(a)(9)-4, Q&A-5. The rules of this Section shall be interpreted consistent with regulations or other guidance prescribed by the Internal Revenue Service under Section 402(c)(11) of the Code.  Solely to the extent permitted in Sections 408A(c)(3)(B),















  





- 38 -











  


















(d)(3) and (e) of the Code and the regulations and other guidance issued thereunder, an eligible Distributee may elect to roll over any portion of an Eligible Rollover Distribution to a Roth IRA (as defined by Section 408A of the Code) in a “Qualified Rollover Contribution” (as defined in Section 408A(e) of the Code), provided that the rollover requirements of Section 402(c) of the Code are met, and provided further that, in the case of an Eligible Rollover Distribution to a non-spouse beneficiary, the Roth IRA is treated as an inherited individual retirement account (within the meaning of Section 408(d)(3)(C) of the Code).  For tax years beginning prior to January 1, 2010, a Distributee will not be eligible to make a Qualified Rollover Contribution unless he or she satisfies the requirements of Section 408A(c)(3)(B) of the Code and the regulations and other guidance issued thereunder.



	
4.8

	
Loans to Participants. While it is the primary purpose of the Plan to accumulate retirement funds for Participants, it is recognized that under some circumstances it is in the best interest of Participants to permit loans to be made to them while they continue in the active service of the Employer.  Accordingly, the Committee, pursuant to such rules as it may from time to time establish and upon application by a Participant supported by such evidence as the Committee requests, may make loans to Participants subject to the following:








	
  

	
(a)

	
The amount of any loan made to a Participant, when added to the outstanding balance of all other loans made to the Participant from all qualified plans maintained by the Employer and any Affiliates shall not exceed the lesser of:








	
  

	
(i)

	
$50,000, reduced by the excess (if any) of:








	
  

	
(A)

	
the highest outstanding balance during the one-year period ending immediately preceding the date of the loan, over















  





- 39 -











  



















	
  

	
(B)

	
the outstanding balance on the date of the loan, of all such loans from all such plans, or








	
  

	
(ii)

	
one-half of the Participant’s total vested account balances under the Plan.








	
  

	
(b)

	
Each loan must be evidenced by a promissory note prepared in a form approved by the Committee and shall bear interest at a commercially reasonable rate as determined by the Committee; provided however, that the applicable interest rate shall not exceed six percent (6%) during any period that the Participant receiving the loan is on military leave, in accordance with the Service members Civil Relief Act. The repayment of any loan must be made in at least quarterly installments of principal and interest; provided, however, that this quarterly amortization requirement shall not apply while a Participant is on a leave of absence (for a period, not longer than one year), if the following conditions are met: (i) the Participant is on leave either without pay from the Employer, or at a rate of pay (after income and employment tax withholding) that is less than the amount of the installment payments required under the terms of the loan; (ii) the loan must be repaid by the latest date permitted under Section 4.8(c), below, and (iii) the installments due after the leave of absence ends (or if earlier, upon the expiration of the first year of the leave of absence) must not be less than those required under the terms of the original loan.








	
  

	
(c)

	
Each loan shall specify a repayment period that shall not extend beyond five years.  If a Participant’s employment is involuntarily terminated in connection with the sale, outsourcing or other divestiture of an Employer, then the Committee may establish uniform rules pursuant to which a Participant may elect a rollover of his or her outstanding loan to an eligible retirement plan.  However, the five-year limit shall not apply to any loan used to acquire any dwelling unit which,















  





- 40 -











  


















within a reasonable time, is to be used (determined at the time the loan is made) as the principal residence of the Participant, in which event the time limit shall be fifteen years.


If upon a Participant’s retirement or other termination of employment, any loan or portion of a loan made to the Participant under the Plan, together with the accrued interest thereon, remains unpaid, an amount equal to such loan or any part thereof, together with the accrued interest thereon, shall be charged to the Participant’s Accounts.


Interest paid by a Participant on a loan made under this Section 4.8 shall be credited to the Accounts of the Participant as of the accounting date which ends the accounting period of the Plan during which such interest payment is made. Outstanding loan balances will be credited with interest at the rate determined pursuant to Section 4.8(b).


The Committee may allow for suspension of loan repayments under the Plan as permitted under Section 414(u)(4) of the Code.

- 42 -











  



















	
4A.2

	
Time and Manner of Distribution








	
  

	
(a)

	
Required Beginning Date. The Participant’s entire interest will be distributed, or begin to be distributed, to the Participant no later than the Participant’s required beginning date.








	
  

	
(b)

	
Death of Participant before Distributions Begin. If the Participant dies before distributions begin, the Participant’s entire interest will be distributed, or begin to be distributed, no later than as follows:








	
  

	
(i)

	
If the Participant’s surviving spouse is the Participant’s sole Designated Beneficiary, distributions to the surviving spouse will begin by December 31 of the calendar year immediately following the calendar year in which the Participant died, or by December 31 of the calendar year in which the Participant would have attained age 701⁄2, if later.








	
  

	
(ii)

	
If the Participant’s surviving spouse is not the Participant’s sole Designated Beneficiary, and if distribution is to be made over the life or over a certain period not exceeding the life expectancy of the Designated Beneficiary (if permitted under Section 4 of the Plan), distribution to the Designated Beneficiary will begin by December 31 of the calendar year immediately following the calendar year in which the Participant died.








	
  

	
(iii)

	
If there is no Designated Beneficiary as of September 30 of the year following the year of the Participant’s death, or if the provisions of subsection (i) and (ii) do not otherwise apply, the Participant’s entire interest will be distributed by December 31 of the calendar year containing the fifth anniversary of the Participant’s death.








	
  

	
(iv)

	
If the Participant’s surviving spouse is the Participant’s sole Designated Beneficiary and the surviving spouse dies after the Participant but before















  





- 43 -











  


















distributions to the surviving spouse begin, this Section 4A.2(b), other than Section 4A.2(b)(i), will apply as if the surviving spouse were the Participant.


For purposes of Sections 4A.2 and 4A.4, unless Section 4A.2(b)(iv) applies, distributions are considered to begin on the Participant’s required beginning date.  If Section 4A.2(b)(iv) applies, distributions are considered to begin on the date distributions are required to begin to the surviving spouse under Section 4A.2(b)(i).  If distributions under an annuity purchased from an insurance company irrevocably commence to the Participant before the Participant’s required beginning date (or to the Participant’s surviving spouse before the date distributions are required to begin to the surviving spouse under Section 4A.2(b)(i)), the date distributions are considered to begin is the date distributions actually commence.



	
  

	
(c)

	
Forms of Distribution.  Unless the Participant’s interest is distributed in the form of an annuity purchased from an insurance company or in a single sum on or before the required beginning date, as of the first distribution calendar year, distributions will be made in accordance with Sections 4A.3 and 4A.4.  If the Participant’s interest is distributed in the form of an annuity purchased from an insurance company, distributions thereunder will be made in accordance with the requirements of Section 401(a)(9) of the Code and the Treasury regulations.








	
4A.3

	
Required Minimum Distributions During Participant’s Lifetime








	
  

	
(a)

	
Amount of Required Minimum Distribution for Each Distribution Calendar Year.  During the Participant’s lifetime, the minimum amount that will be distributed for each distribution calendar year is the lesser of:















  





- 44 -











  



















	
  

	
(i)

	
the quotient obtained by dividing the Participant’s Account balance by the distribution period in the Uniform Lifetime Table set forth in Section 1.401(a)(9)-9 of the Treasury regulations, using the Participant’s age as of the Participant’s birthday in the distribution calendar year; or








	
  

	
(ii)

	
if the Participant’s sole Designated Beneficiary for the distribution calendar year is the Participant’s spouse, the quotient obtained by dividing the Participant’s Account balance by the number in the Joint and Last Survivor Table set forth in Section 1.401(a)(9)-9 of the Treasury regulations, using the Participant’s and spouse’s attained ages as of the Participant’s and spouse’s birthdays in the distribution calendar year.








	
  

	
(b)

	
Lifetime Required Minimum Distributions Continue  Through Year of Participant’s Death.  Required minimum distributions will be determined under this Section 4A.3 beginning with the first distribution calendar year and up to and including the distribution calendar year that includes the Participant’s date of death.








	
4A.4

	
Required Minimum Distributions After Participant’s Death








	
  

	
(a)

	
Death on or after Date Distributions Begin.








	
  

	
(i)

	
Participant Survived by Designated Beneficiary.  Subject to the provisions of this Article, if the Participant dies on or after the date distributions begin and there is a Designated Beneficiary, the minimum amount that will be distributed for each distribution calendar year after the year of the Participant’s death is the quotient obtained by dividing the Participant’s Account balance by the longer of the remaining life expectancy of the Participant or the remaining life expectancy of the Participant’s Designated Beneficiary, determined as follows:















  





- 45 -











  



















	
  

	
(A)

	
The Participant’s remaining life expectancy is calculated using the age of the Participant in the year of death, reduced by one for each subsequent year.








	
  

	
(B)

	
If the Participant’s surviving spouse is the Participant’s sole Designated Beneficiary, the remaining life expectancy of the surviving spouse is calculated for each distribution calendar year after the year of the Participant’s death using the surviving spouse’s age as of the spouse’s birthday in that year.  For distribution calendar years after the year of the surviving spouse’s death, the remaining life expectancy of the surviving spouse is calculated using the age of the surviving spouse as of the spouse’s birthday in the calendar year of the spouse’s death, reduced by one for each subsequent calendar year.








	
  

	
(C)

	
If the Participant’s surviving spouse is not the Participant’s sole Designated Beneficiary, the Designated Beneficiary’s remaining life expectancy is calculated using the age of the Beneficiary in the year following the year of the Participant’s death, reduced by one for each subsequent year.








	
  

	
(ii)

	
No Designated Beneficiary.  If the Participant dies on or after the date distributions begin and there is no Designated Beneficiary as of September 30 of the year after the year of the Participant’s death, the minimum amount that will be distributed for each distribution calendar year after the year of the Participant’s death is the quotient obtained by dividing the Participant’s Account balance by the Participant’s remaining















  





- 46 -











  


















life expectancy calculated using the age of the Participant in the year of death, reduced by one for each subsequent year.



	
  

	
(b)

	
Death Before Date Distributions Begin








	
  

	
(i)

	
Participant Survived by Designated Beneficiary.  If the Participant dies before the date distributions begin and there is a Designated Beneficiary, the minimum amount that will be distributed for each distribution calendar year after the year of the Participant’s death is the quotient obtained by dividing the Participant’s account balance by the remaining life expectancy of the Participant’s Designated Beneficiary, determined as provided in Section 4A.4(a).








	
  

	
(ii)

	
No Designated Beneficiary. If the Participant dies before the date distributions begin and there is no Designated Beneficiary as of September 30 of the year following the year of the Participant’s death, distribution of the Participant’s entire interest will be completed by December 31 of the calendar year containing the fifth anniversary of the Participant’s death.








	
  

	
(iii)

	
Death of Surviving Spouse Before Distributions to Surviving Spouse Are Required to Begin.  If the Participant dies before the date distributions begin, the Participant’s surviving spouse is the Participant’s sole Designated Beneficiary, and the surviving spouse dies before distributions are required to begin to the surviving spouse under Section 4A.2(b)(i), this Section 4A.4(b) will apply as if the surviving spouse were the Participant.

5.1

	
Making of Contributions. Once each month, or as otherwise determined by the Committee subject to the Employer’s consent, the Employer will pay over contributions to the Trustee to be held in trust and invested as herein provided and as set out more fully in the Trust Agreement.  The Employer’s matching contributions and Profit Sharing contributions, if any, shall not be made later than the due date for filing the Employer’s federal income tax return for the Tax Year, including any extensions thereof.  The contributions to this Plan when taken together with all other contributions made by the Employer to other qualified retirement plans shall not exceed the maximum amount deductible under Section 404 of the Code.








	
5.2

	
Investment








	
  

	
(a)

	
Each Participant’s Savings Contribution Account and Rollover Account and earnings credited to such Accounts on and after the Effective Date will be invested in one or more of the Investment Funds. Each Participant will designate the proportion (expressed as a percentage in multiples of one percent (1%)) of such Participant’s Savings Contribution Account and Rollover Account to be invested in each Investment Fund.  Such designation, once made, can be changed at any time and will take effect as soon as administratively feasible. Participants may also, at any time and independent of changing their election of investment of future savings contributions, transfer the amount equivalent to the Participant’s interest or any partial interest (expressed as a percentage in multiples of one percent (1%)) from one Investment Fund to another. Any designation made under this Section 5.2(a) shall be made pursuant to the methods described in Section 3.1(c).















  





- 50 -











  



















	
  

	
(b)

	
Each Participant shall have an interest in each Investment Fund in which the Participant has elected to have invested all or any part of the Participant’s savings contributions under Section 3.1.  The Participant’s interest at any time in the Investment Funds shall be equal to such contributions, adjusted from time to time to reflect the proportionate share of the income and losses realized by such Investment Funds and of the net appreciation or depreciation in the value of such Investment Funds.  The Committee shall maintain accounts to reflect the interest of each Participant in each Investment Fund. At such times as the Committee may determine, but in no event less frequent than annually, the Committee shall ascertain from the Trustee the value of each Investment Fund and shall on such basis determine the value of the interests of each Participant. The determinations of the Trustee and the Committee shall be conclusive. Each Participant will be furnished a statement of Account at least annually.








	
  

	
(c)

	
Moreover, for any period in which the Plan is an “applicable defined contribution plan” as defined in Section 401(a)(35) of the Code by virtue of the Plan holding applicable publicly traded employer securities, the Company shall permit Participants, beneficiaries, and alternate payees to direct the investment of their accounts under rules and procedures that comply with Section 401(a)(35) of the Code and applicable Treasury Regulations thereunder.







 



	
5.3

	
Voting of Common Stock of the Company.  Each Participant shall have the right to direct the Trustee as to the manner in which shares of Common Stock allocated to the Participant’s Accounts are to be voted.  The Company shall furnish the Trustee and the Participants with notices and information statements when voting rights are to be exercised, in such time and manner as may be required by applicable law and the















  





- 51 -











  


















Certificate of Incorporation and Bylaws of the Company.  Such statements shall be substantially the same for Participants as for holders of Common Stock in general. The Participant may, in the Participant’s discretion, grant proxies for the exercise of the Participant’s voting rights under this Section 5.3 in accordance with proxy provisions of general application.  The Trustee shall vote such Common Stock in accordance with the direction of the Participant. Fractional shares of Common Stock allocated to Participants Accounts shall be combined to the largest number of whole shares and voted by the Trustee to the extent possible to reflect the voting direction of the Participants holding fractional shares.  Subject to the terms of the immediately following sentence, the Trustee shall vote Allocated Shares of the Company’s Common Stock for which it has not received valid direction proxies (the “Non-Directed Shares”) and any shares that have not been allocated to Plan participants’ accounts in accordance with the Board’s recommendation on all of the matters.



	
5.4

	
Tendering of Stock.  A Participant (or in the event of death, the beneficiary) shall have the right to instruct the Trustee in writing as to the manner in which to respond to a tender or exchange offer in any and all shares of Common Stock credited to such Participant’s Accounts. The Employer shall notify each Participant (or beneficiary) and utilize its best efforts to distribute or cause to be distributed in a timely fashion such information as will be distributed to shareholders of the Employer in connection with any such tender or exchange offer, together with a form requesting confidential instruction to the Trustee as to the manner in which to respond to the tender or exchange offer for any or all shares of Common Stock credited to such Participant’s Accounts. Upon its receipt of such instructions, the Trustee shall tender such shares of such Common Stock as and to the extent so instructed. If the Trustee shall not receive instructions from a Participant (or beneficiary) regarding any such tender or exchange offer for Common Stock, the















  





- 52 -











  


















Trustee shall have no discretion in such matter and shall take no action with respect thereto.



	
5.5

	
Dividend Election.  Effective as of May 25, 2006, each Participant (or, where applicable, a Participant’s Designated Beneficiary or an alternate payee) will have the right to elect to receive a cash payment of the dividends, if any, paid on all shares (vested or unvested) of Common Stock in the Participant’s ESOP Account or to reinvest such vested dividends in Common Stock in the Participant’s ESOP Account.  Participants shall be fully vested in all dividends, if any, paid on the shares of Common Stock held in the Participant’s ESOP Account. If a Participant (or the Participant’s Designated Beneficiary or an alternate payee) does not make an affirmative election under this Section, the Participant will be deemed to have elected to reinvest vested dividends in the ESOP account.  The Committee will establish rules and procedures for the election, including the procedures for determining the number of shares of Common Stock in each Participant’s ESOP Account on the record date of the dividend. Reinvested dividends will be paid to the Plan and credited to the Participant’s ESOP Account.  If a Participant elects to receive dividends in cash, such dividends shall be paid to the Participant by the Plan and shall not constitute Eligible Rollover Distributions under Section 4.7.  Partial elections (i.e., electing to receive part of a dividend in cash and to reinvest part) shall not be permitted.

6.3

	
Benefit Claims Procedure: Review Procedure.








	
  

	
(a)

	
The Committee shall make all determinations as to the right of any such person to a benefit under the Plan. Any Participant, beneficiary, or the authorized representative of either of the foregoing may file a request for benefits under the Plan. Such request shall be deemed filed when made in writing, addressed, or hand-delivered to the Employer.








	
  

	
(b)

	
The Committee shall determine the entitlement of each claimant to the benefit requested within ninety (90) days after the request is filed unless an extension of time for processing is required.  In such event, written notice of the extension shall be furnished to the claimant prior to the expiration of such ninety (90) day period.  In no event may an extension exceed an additional ninety (90) days from the expiration of the end of the initial ninety (90) day period. Any such extension notice shall indicate the special circumstances requiring the extension of time and the date by which the Committee expects to render its decision.  In the event that such Committee does not respond to a claimant within the foregoing time limit, including any extension, the claimant’s request for a benefit shall be deemed to be denied in full and such claimant shall be entitled to proceed to the review stage described in paragraph (d).








	
  

	
(c)

	
In the event that a claimant’s request for benefits is denied in whole or in part, such claimant shall be furnished with a written notice of the Committee’s decision which sets forth (1) the specific reason or reasons for denial, (2) specific reference to the pertinent Plan provisions upon which the denial is based, (3) a description of any additional material or information necessary for the claimant to perfect the claim and an explanation of why any such material or information is















  





- 56 -











  


















necessary,  and (4) appropriate information as to the steps to be taken if the claimant wishes to submit the claim for review.



	
  

	
(d)

	
Any claimant whose request for benefit is denied in whole or in part by the Committee shall be entitled to request the Committee to give further consideration to the claim by filing with such Committee (either by the claimant or through the claimant’s authorized representative) a written request for such a review.  The claimant desiring a review may submit written issues and comments to the Committee for its consideration and shall be entitled to review any documents pertinent to such Committee’s decision.  The Committee, in its sole discretion, may request a meeting to clarify any matters which it deems appropriate. Subject to the limitations of paragraph (e), the Committee shall render its decision on review as soon as practicable.  In the event that no decision is rendered within such limitations, the claimant’s request for benefits shall be deemed denied a review.








	
  

	
(e)

	
Any request for a review of the Committee’s decision must be filed within sixty (60) days after receipt by the claimant of written notification of denial of the request for benefits.  If no request is received within such time limit, the denial of benefits determined by the Committee shall be final.  If a request for review is filed, the Committee shall promptly consider such request and shall render its decision thereon within sixty (60) days after the receipt of the request for review, absent special circumstances (such as the need to hold a hearing), which require an extension of time for processing.  In no event shall the decision be rendered more than one hundred and twenty (120) days after the receipt of a request for a review.  In the event that at the time such a request for review is filed the Committee has established a practice of holding regularly scheduled meetings on















  





- 57 -











  


















at least a quarterly basis, such decision shall be made at the next ensuing regular meeting unless the request for review is filed within thirty (30) days preceding the date of such meeting.  In such event, a decision may be made by the Committee no later than the date of the second ensuing regularly scheduled meeting following the receipt of the request for review, unless special circumstances require a further extension of time for processing.  In no event may the decision be rendered later than the third meeting of the Committee following the receipt of the request for review.



	
  

	
(f)

	
Benefits under this Plan will be paid only if the Committee, or its delegate, determines in its sole discretion that the claimant is entitled to them.  Subject to applicable law, any interpretation of the provisions of the Plan and any decisions on any matter within the discretion of the Committee made by the Committee in good faith shall be binding on all persons.  A misstatement or other mistake of fact shall be corrected when it becomes known and the Committee shall make such adjustment on account thereof as it considers equitable and practicable.








	
  

	
(g)

	
After exhaustion of the Plan’s claim procedures, any further legal action taken against the Plan or its fiduciaries by any claimant for benefits under the Plan must be filed in a court of law no later than 60 days after the Committee’s final decision regarding the claim.

The affirmative designation of any beneficiary and any elected change or revocation thereof by a Participant shall be made on forms provided by the Committee and shall not in any event be effective unless and until filed with the Committee.

Expenses directly related to the investment of a particular Investment Fund (such as brokerage, postage, express and insurance charges, and transfer taxes) shall be paid from that Investment Fund.

Trust Agreement. All assets of the Plan shall be held under the Trust Agreement between the Company and the Trustee designated by the Company which shall serve at the pleasure thereof.  The Trust Agreement shall provide, among other things, for a Trust Fund to be administered by the Trustee to which all contributions shall be paid, and the Trustee shall have such rights, powers, and duties as the Company shall from time to time determine.

The amount of any contribution that may be returned to the Employer must be reduced by any portion thereof previously distributed from the Trust Fund and by any losses of the Trust Fund allocable thereto, and in no event may the return of such contribution cause any Participant’s account balances to be less than the amount of such balances had the contribution not been made under the Plan.

ARTICLE X







GENERAL



	
10.1

	
No Guarantee of Employment.  Nothing contained in the Plan shall be construed as a contract of employment between the Employer and any Eligible Employee or Participant, or a right of any Eligible Employee or Participant to be continued in the employment of the Employer, or as a limitation of the right of the Employer to discharge any of its employees.








	
10.2

	
Nonalienation of Benefits.  Except to the extent otherwise provided by Section 401(a) (13) (C) or by the issuance of a qualified domestic relations order (within the meaning of Section 414(p), or such successor Section, of the Code), benefits payable under the Plan shall not be subject in any manner to anticipation, alienation, sale, transfer, assignment, pledge, encumbrance, charge, garnishment, execution, or levy of any kind, either voluntary or involuntary, including any such liability which is for alimony or other payments for the support of a spouse or former spouse, or for any other relative of the Participant, prior to actually being received by the person entitled to the benefit under the terms of the Plan; and any attempt to anticipate, alienate, sell, transfer, assign, pledge, encumber, charge, or otherwise dispose of any right to benefits payable under the Plan, shall be void.








	
10.3

	
Missing Persons.  Any communication, statement, or notice addressed and mailed, postage prepaid, to a Participant for beneficiary) at the latest post office address as stated on the books and records of the Company shall, without limitation, constitute an effective notice upon such person for all purposes of the Plan, and the Employer shall not be obligated to search for or ascertain the whereabouts of any such person.

10.4

	
Governing Law.  Except as preempted by federal law, the provisions of the Plan will be construed in accordance with the laws of the State of North Dakota.








	
10.5

	
Merger or Consolidation of Plan.  In the event of any merger or consolidation of the Plan with, or transfer in whole or in part of the assets and liabilities of the Accounts to, another plan, the assets of the Participants’ Accounts shall be transferred to the other plan only if each Participant would, if the Plan or the other plan then terminated, receive a benefit immediately after the merger, consolidation, or transfer which is equal to or greater than the benefit the Participant would have been entitled to receive if the Plan had been terminated immediately before the merger, consolidation, or transfer.








	
10.6

	
Distribution to Alternate Payees.

ARTICLE XI








	
  

	
TOP HEAVY PROVISIONS








	
11.1

	
Top Heavy Plan.  The Plan shall be deemed “Top Heavy” with respect to any Plan Year commencing on or after January 1, 1984 if, as of the last day of the preceding Plan Year (the “Determination Date”), the present value of the cumulative account balances for “Key Employees,” as defined in Code Section 416(i), under the Plan and all other plans in the “Aggregation Group,” as defined below, exceeds 60 percent of the present value, as of the Determination Date, of the cumulative account balances under all such plans for all employees of the Employer.  For purposes of this Section XI, (i) the term “Aggregation Group” shall mean each plan of the Employer in which a Key Employee participates and each other plan of the Employer which enables such plan to meet the requirements of Code Section 401(a)(4) or 410; (ii) the present value of such account balances shall be computed in accordance with Code Section 416(g); and (iii) the above percentage ratio shall be determined as of the Determination Date by a fraction, the numerator of which is the sum of the present value of the account balances of Key Employees under the Plan and all other plans in the Aggregation Group, and the denominator of which is the sum of the present value of the account balances under all such plans, including the Plan, for all employees of the Employer.  The accrued benefits of a Participant who did not perform any services for an Employer during the 1 year period ending on the Determination Date shall be disregarded.








	
11.2

	
Operative Provisions








	
  

	
(a)

	
For any Plan Year with respect to which the Plan is deemed Top Heavy, the Employer shall make a Retirement Contribution on behalf of each Participant who is not a Key Employee with respect to such Plan Year in an amount which, when added to the Employer’s matching contribution, if any, made under the















  





- 69 -











  


















Plan on behalf of such Participant for such Plan Year, equals 3 percent of the Participant’s Compensation.  Any such special Employer contributions that are used to satisfy the minimum contribution requirements shall be treated as matching contributions for purposes of the actual contribution percentage test and other requirements of Section 401(m) of the Code. Notwithstanding the foregoing provisions of this Section 11.2, if a Participant in the Plan is also a Participant in a defined benefit plan of the Employer, then for each Plan Year with respect to which the Plan is Top Heavy, such Participant’s accrual of a minimum benefit under such other defined benefit plan in accordance with Code Section 416(c)(1) shall be deemed to satisfy the special Employer’s contribution requirements of this Section 11.2(a).



	
  

	
(b)

	
In the event the Plan is deemed “Top Heavy” pursuant to Section 11.1, each Participant shall have a nonforfeitable right to the Participant’s entire Account balances, including those amounts attributable to the Retirement Contributions under this Section 11.2.








	
  

	
(c)

	
Notwithstanding the provisions of Section 3.5, if during any Plan Year an employee of the Employer participates in both a defined contribution plan and a defined benefit plan maintained by the employer which comprise a Top Heavy Group, as defined in Code Section 416(9)(2)(B), the denominators of the defined benefit plan fraction and the defined contribution plan fraction, as described in Code Section 415(e), shall be calculated by substituting “1.0” for “1.25” each place it appears in such Section; provided, however, that this Section 11.2(c) shall not apply with respect to a plan in the Top Heavy Group if (a) such plan would satisfy the requirements of Code Section 416(h)(2)(A), and (b) the aggregate cumulative accrued benefits and account balances of Key Employees















  





- 70 -











  


















under all plans in the Top Heavy Group do not exceed 90 percent of the aggregate accrued benefits and cumulative account balances under all such plans for all employees of the Employer.  The provisions of this paragraph shall cease to apply after December 31, 1999.

ARTICLE XII








	
  

	
SPECIAL RULES FOR CERTAIN OFFICERS








	
12.1

	
Notwithstanding the provisions set forth above, Section 16 Officers are subject to special limitations on their ability to effect certain transactions under the Plan, as follows:  The Section 16 Officer may affect “Discretionary Transactions,” as defined below, only in compliance with Rule 16b-3(f) of the Securities Exchange Act of 1934, as amended.







A “Discretionary Transaction” is a transaction pursuant to an employee benefit plan that

is at the volition of a Plan Participant;








	
  

	
(b)

	
is not made in connection with the Participant’s death, retirement, or termination of employment;








	
  

	
(c)

	
is not required to be made available to a Plan Participant pursuant to a provision of the Internal Revenue Code; and








	
  

	
(d)

A Discretionary Transaction shall be exempt only if affected pursuant to an election made at least six months following the date of the most recent election, with respect to any plan of the Company that affected a Discretionary Transaction that was:



	
  

	
(a)

	
an acquisition, if the transaction to be exempted would be a disposition; or








	
  

	
(b)

	
a disposition, if the transaction to be exempted would be an acquisition.

G-6

	
Supplemental Contributions. An Employer, in its sole discretion, may make a supplemental contribution on behalf of any Davis-Bacon Employee, other than a Davis-Bacon Employee who is a Highly Compensated Employee, (a “Davis-Bacon Supplemental Contribution”) (i) in such amount as may be necessary to satisfy the Prevailing Wage Law’s required fringe cost to the extent that the sum of the employer Matching and Profit Sharing Contributions, if any, for a period are insufficient to satisfy the Prevailing Wage Law’s required fringe cost or (ii) in such amount as may be necessary to satisfy the Prevailing Wage Law’s required fringe cost without regard to any employer Matching and Profit Sharing Contributions made on behalf of such Davis-Bacon Employee.  Any Davis-Bacon Supplemental Contributions made on behalf of a Davis-Bacon Employee pursuant to this paragraph G-6 shall be credited to a “Davis-Bacon Supplemental Contribution Account” established for the Davis-Bacon Employee under this Supplement G.  Except as otherwise provided in this Supplement G, Davis-Bacon Employee’s Supplemental Contribution Account shall be treated as an “Account” for all purposes of the Plan and the amounts credited thereto shall be subject to the same restrictions as apply to amounts credited to a Participant’s Profit Sharing Account.

Depositing of Employer Contributions.  Any Employer contribution made on behalf of a Davis-Bacon Employee under the Plan that is intended to satisfy the Prevailing Wage Law’s required fringe cost, including, but not limited to, any matching contributions and any Davis-Bacon Supplemental Contributions described in paragraph G-6 above, will be contributed to the Trust Fund not less frequently than quarterly.

G-10

	
Contribution Limitation.  If the annual additions that would otherwise be allocated to a Davis-Bacon Employee’s Accounts would exceed the limitations described in Section 3.7 of the Plan for any Plan Year, any portion of the excess amount that is attributable to contributions made on behalf of the Davis-Bacon Employee with respect to Davis-Bacon Service shall be held in a suspense account and allocated and reallocated to the Davis-Bacon Employee’s Accounts in subsequent Plan Years to the extent permissible in accordance with Treasury Regulation Section 1.415-6(b)(6).
