Offer Letter to Jay B. Knoll, dated November 17, 2022

Dear Jay:

We are pleased to offer you the position of Senior Vice President, General Counsel and Secretary, Barnes (“Barnes” or the “Company”) at an annual salary of $460,000 (paid monthly in advance), effective January 1, 2023, or your date of employment. In this position you will report to me and have an office in Bristol, Connecticut. This offer supersedes and replaces any prior written or oral offer of employment.

Effective January 1, 2023 (or the effective date of your employment, if later than 1/1/2023, on a pro-rated basis), you will participate in the Performance-Linked Bonus Plan for Selected Executive Officers. Your target incentive under this plan is 55% of base salary, with a maximum payout of 110% of base salary. Your incentive payout will be based on 100% Barnes Corporate (consolidated) results which are comprised of 60% Earnings Per Share (EPS), 20% Operating Profit, and 20% Revenue. Your total cash compensation package is $713,000 at target and $966,000 at maximum on an annualized basis. Annual incentive payouts are subject to the provisions of the plan and are normally paid in late February of the year immediately following the plan year (i.e., payouts for the 2023 plan year, if any, are expected to be paid in late February 2024). You must be employed on the date bonuses are paid to be eligible for a payout.

You will receive a special one-time cash award, payable within 30 days from your date of employment, in the amount of $240,900 (less applicable tax withholdings) in lieu of your 2022 annual cash incentive award from your prior employer. The cash award is subject to full reimbursement to Barnes should you voluntarily terminate your employment within eighteen (18) months from the date of payment.

As part of your offer, you will be awarded long-term equity during the normal annual grant cycle in February 2023, as follows:

•8,855 Performance Share Awards, with each unit having the equivalent value of one share of Barnes stock. Performance share awards are based on three equally weighted measures and vest based on the performance of Barnes over three years. Two of the performance measures, Total Shareholder Return (TSR) and EBITDA Growth are measured on a relative basis against the Russell 2000 companies. The third measure, Return on Invested Capital (ROIC), is measured on an absolute basis against “pre-established targets” as set by the Compensation and Management Development Committee of the Board of Directors. Shares earned, if any, will be paid out upon vesting. Dividends will accrue on this performance share award and be paid in the same ratio as the underlying shares.

•5,313 Time-vested Restricted Stock Units, with each unit having the equivalent value of one share of Barnes stock. The restrictions will lapse one-third each on the 18th, 30th, and 42nd month anniversaries of the date of grant. You will receive dividends on these restricted stock units as such dividends are declared by the Company.

•10,095 Stock Options, with an exercise price equal to the fair market value of Barnes stock (as defined in the 2014 Barnes Stock and Incentive Award Plan) on the grant date. These options will vest one-third each on the 18th, 30th, and 42nd month anniversaries of the date of grant. Stock options are a speculative financial vehicle driven solely by stock price appreciation. Fair market value stock options have no intrinsic value absent such appreciation.

Your current target value for annual long-term compensation is $690,000. We currently expect these awards to be in the form of stock options, restricted stock units, and performance share awards. All awards are subject to the discretion of the Compensation and Management Development Committee.

In addition, you will also receive a special one-time new hire equity grant, currently valued at approximately $450,000, as follows:

•11,550 Time-vested Restricted Stock Units, with each unit having the equivalent value of one share of Barnes stock. The restrictions will lapse one-third each on the 18th, 30th, and 42nd month anniversaries of the date of grant. You will receive dividends on these restricted stock units as such dividends are declared by the Company.

You will be expected to sign an agreement that provides that, in certain circumstances, you may be subject to a “claw back” of any cash or equity awards earned if the Company restates its financial results lower than those upon which awards were calculated (with the exception of restatements not caused by misconduct or error) to comply with generally accepted accounting principles.

Stock ownership guidelines have been established for our leadership team to ensure that management’s interests are aligned with our stockholders’ interests. The guideline for your position is three times (3x) your base salary. Ownership includes directly and beneficially owned shares, stock retained following the distribution of vested restricted stock units and earned performance share awards, and exercises of stock options, stock unit holdings under the Barnes Retirement Savings Plan (RSP), and stock owned through the Barnes Employee Stock Purchase Plan (ESPP). In addition, two-thirds of the value of unvested restricted stock units will be credited toward ownership guidelines. Shares granted by the Company (100% of the after-tax value of equity grants vesting, or options exercised) must be retained until you have met your ownership guidelines. Once met, your multiple of salary requirement converts into a “fixed” number of shares needed to meet that requirement. Going forward, participants must maintain, at minimum, their “fixed” number of shares while employed with the Company in an ownership designated position. While there is no specific timeframe requirement for achieving the ownership requirement, participants are expected to make steady progress and maintain ownership of any shares realized through vesting of restricted stock units, performance share awards, and stock option exercises.

In addition to your annual salary and incentive compensation, Barnes offers a comprehensive employee benefits package, including:

•Medical and Prescription Drug Insurance (contributory on a pre-tax cost-sharing basis).

•Dental Insurance (contributory on a pre-tax cost-sharing basis).

•Vision Insurance (contributory).

•Employee Stock Purchase Plan featuring a 5% discount off fair market value of Barnes stock, subject to statutory limits.

•Retirement Savings 401(k) Plan with a Company matching contribution of 50% on the first 6% of your pre-tax contributions. The Plan offers a wide range of investment funds to choose from.

•4% Retirement Contribution (Company funded based on eligible earnings) deposited annually into your Retirement Savings 401(k) Account.

•4% Retirement Contribution to the Defined Contribution Retirement Benefit Equalization Plan (DC RBEP) for eligible compensation in excess of annual IRS limits, deposited annually into your Retirement Savings 401(k) Account.
