Executive Employment Agreement, dated August 13, 2021, by and between Fast Radius, Inc. and Prithvi Gandhi

“Cause” for termination exists at any time (including during the Initial Term) if the Executive: (i) is convicted of any felony or other crime involving dishonesty or moral turpitude (but specifically excluding minor traffic offenses and other similar minor infractions), (ii) materially breaches this Agreement, (iii) refuses to materially perform his duties reasonably requested by the Board and typically performed by Executive for any reason other than mental or physical disability, (iv) materially fails to observe the Company’s written policies that are generally applicable to executives of the Company, a copy of which was provided to the Executive, or (v) engages in gross negligence, gross misconduct or fraud in connection with his employment by the Company; provided, however, that the Board must notify the Executive of the specific deficiencies under clauses (ii) through (v) and afford the Executive thirty (30) days to cure such performance deficiencies before Cause for termination would arise.

“Competing Products” means any web-enabled on-demand manufacturing solution.

“Disability” means that the Executive is unable to perform, by reason of physical or mental incapacity, the essential functions of his position with or without reasonable accommodation for ninety (90) or more days in any one hundred twenty (120)-day period.

“Good Reason” exists for the Executive to terminate his employment if any of the following occurs without the Executive’s consent; (i) a reduction of Executive’s then current Base Salary; (ii) a material diminution in Executive’s title, authority, rank, duties or responsibilities; (iii) the Company materially breaches this Agreement; or (iv) a required relocation of the Executive’s primary work location fifty (50) miles from the Executive’s primary work location as of the Commencement Date; provided, however, the Executive’s voluntary termination of his employment shall be deemed for “Good Reason” only if the Executive has provided the Board written notice (by notice to the Company in accordance with the notice provisions hereof) identifying in reasonable detail the facts giving rise to Good Reason within ninety (90) days of the Executive’s becoming aware thereof, the Board has failed to cure any such issues within thirty (30) days after receipt of such notice, and the Executive’s termination of his employment is effective within sixty (60) days after such notice.

“Restricted Territory” means anywhere in the world.

“Incentive Equity” means all previously granted and future options, RSU and other equity instruments.

The Executive’s employment by the Company shall be for a term commencing on August 18, 2021 (“Commencement Date”) and expiring on the close of business on March 15, 2025 (the “Initial Term”); provided that the Company may terminate this Agreement and Executive’s employment at any time during the Initial Term for Cause or without Cause pursuant to the terms of Section 4 below. Such termination shall not be deemed a breach of this Agreement, nor shall the Company be required to compensate or provide benefits to the Executive for the remaining portion of the Initial Term. After the Initial Term, Executive’s employment shall continue until either party provides written notice of termination (a “Notice of Termination”) (the Initial Term and the period, if any, thereafter, during which the Executive’s employment shall continue are collectively referred to as the “Term”). Any Notice of Termination given under this Section 2 shall specify the date of expiration of the Term (which may not be earlier than the close of business on March 15, 2025) and may be given at any time on or after March 15, 2025. A termination of employment by the giving of a Notice of Termination under this Section 2 shall not be deemed to be a termination without Cause. The date on which the Executive ceases to be employed by the Company, regardless of the reason therefore is referred to in this Agreement as the “Termination Date”.

The Company agrees to hire the Executive as Chief Financial Officer, with duties and authority customarily associated therewith. The Executive shall report to the Chief Executive Officer.

An annual base salary of $400,000 (the “Base Salary”) less all applicable withholdings, paid on the Company’s regularly scheduled payroll dates, and subject to increase but not decrease.

Incentive Equity.

Subject to the approval of the Compensation Committee of the Board of Directors of the Company (the “Compensation Committee”) following the consummation of the Company’s business combination with ECP Environmental Growth Opportunities Corp. (the “Business Combination”) and the filing of a Form S-8 registration statement by the Company with respect to the Fast Radius, Inc. 2021 Equity Incentive Plan (the “2021 Plan”) (such filing, the “S-8 Filing”), the Company will grant to the

In addition to the Initial Grant or grant of other Incentive Equity of comparable value, and conditioned on the approval of the Compensation Committee and the closing of the Business Combination, Executive will be eligible to receive a supplemental grant of 20,000 restricted stock units under the 2021 Plan (the “Second Grant”), which restricted stock units shall be subject to the terms of a grant agreement to be executed between Executive and the Company, including that such restricted stock units will fully vest as of the date that is six (6) months after the closing of the Business Combination.

The Executive will also be eligible to participate generally in the 2021 Plan with the executive team and other employees. Regardless of whether the Business Combination closes, but in any event conditioned on the approval of the Compensation Committee, Executive will be eligible to receive an additional grant of Incentive Equity during the first half of calendar year 2022 and each calendar year thereafter.

Executive will be eligible to receive an annual target incentive bonus of $220,000 (the “Annual Bonus”). The Annual Bonus shall be based upon Executive meeting the annual applicable benchmarks determined by the Board in its sole and absolute discretion and communicated to the Executive. Each Annual Bonus shall not vest and shall be deemed earned only when paid. In cases of any termination event initiated by the Company, other than for Cause, or for a termination event initiated by the Executive for Good Reason, the annual bonus shall be deemed earned ratably on a monthly basis. The total earned portion of each Annual Bonus shall be paid out during the first payroll period of February following the calendar year in which such Annual Bonus is earned; provided, that if the Board determines that payment of the Annual Bonus in cash would be materially detrimental to the survival of the Company, payment of the Annual Bonus may be delayed until the Company is able to pay such delayed Annual Bonus. Executive’s Annual Bonus, if any, for calendar year 2021 will be prorated based on the partial year following the Commencement Date.

Participation in all benefits plans, including welfare benefit and retirement plans and programs, and entitlement to receive fringe benefits and perquisites, in each case in accordance with the Company’s plans from time to time in effect which are made available by the Company to its senior executives and, without duplication, its employees generally; provided, that the Company will obtain standard disability insurance for its senior executives.

Four (4) weeks of vacation per year, and as many holidays, sick days and personal days as are in accordance with the Company’s policy then in effect for its senior executives and, without duplication, its employees generally.

Subject to Section 9(c) of this Agreement and in accordance with the Company time and expense policies, reimbursement for expenses reasonably incurred by the Executive in connection with his employment.

Commuting and Relocation Costs.

In connection with Executive’s employment with the Company, Executive will initially work remotely with travel as needed to the Company’s Chicago, Illinois offices. Executive agrees that Executive will use Executive’s best efforts to relocate permanently to the Chicago, Illinois metropolitan area no later than January 1, 2022.

From the Commencement Date through December 31, 2021, Executive will be eligible to receive reimbursement for the following expenses related to Executive temporarily commuting from Executive’s home in the Toledo, Ohio area to the Company’s offices in Chicago, Illinois: (a) reasonable airfare expenses for travel between Toledo, Ohio and Chicago, Illinois, and (b) overnight accommodations at hotels in the Chicago, Illinois area, in each case as approved by the Company. Any such reimbursements will be subject to the Company’s reimbursement policies, including that appropriate documentation be provided. For purposes of clarity, the Company will not be responsible for reimbursement of local transportation and meal costs during Executive’s travel to the Chicago, Illinois area, which costs will be exclusively Executive’s responsibility. As of January 1, 2022, regardless of whether Executive has actually relocated to the Chicago, Illinois metropolitan area, Executive will no longer be eligible for reimbursement of commuting expenses to Chicago, Illinois, and all such costs (including for airfare and overnight accommodations) will be Executive’s responsibility. Any reimbursement for commuting expenses provided pursuant to this Section shall be paid in 2021 or 2022 (but in any event no later than March 15, 2022).

As payment for Executive’s agreement to relocate Executive and Executive’s family to the Chicago, Illinois metropolitan area, the Company will provide Executive with a relocation bonus in the gross amount of $75,000 (the “Relocation Bonus”) to cover moving expenses and any other costs incurred in moving Executive and Executive’s family to the Chicago, Illinois area, which shall be paid in 2021 within thirty (30) days of the Commencement Date. If Executive has not permanently relocated Executive and Executive’s family to the Chicago, Illinois metropolitan area by January 1, 2022, Executive agrees to repay to the Company the entire Relocation Bonus, no later than January 31, 2022. By Executive’s signature below, Executive further agrees that the Company may deduct, and is hereby authorized to deduct, any such repayment amount owed from

To the extent that any payment or reimbursement provided pursuant to this Section 3(g) will be subject to tax as ordinary income, Executive will be responsible for the employee portion of all such taxes.

During the Term and for so long thereafter as liability exists with regard to the Executive’s activities during the Term on behalf of the Company, the Company shall defend, indemnify and hold harmless the Executive (other than in connection with the Executive’s gross negligence or willful misconduct) for all actions undertaken by the Executive on behalf of the Company in accordance with the Company’s customary indemnification policies and procedures which are applicable to the Company’s officers and directors.

During the Term, the Company shall cause the Executive to be listed as a named insured, or otherwise covered as an insured person, under such generally applicable directors and officers insurance coverage as it may elect to maintain from time to time. The Company shall use commercially reasonable efforts to cause the Executive to continue to be listed as a named insured, or otherwise covered as an insured person, under such generally applicable directors and officers insurance coverage as it may elect to maintain from time to time for a reasonable period (which shall in no event exceed six (6) years) after the Employment Period, provided that such coverage for the Executive is reasonably available from the Company’s then-existing insurance compan(ies) and is reasonably priced, in each case as determined by the Company in its good faith discretion.

Upon termination of the Executive’s employment, regardless of which party initiates the same and regardless of reason, the Executive shall be entitled to any owed wages, subject to the payment terms set forth in Sections 3(b) and 3(c), plus reimbursement of any unpaid expenses outstanding as of the Termination Date.

If the Executive terminates his employment during the Initial Term without Good Reason, his employment is terminated for Cause, or either party issues a Notice of Termination after the Initial Term, the Executive shall only be paid his earned wages and any reimbursable expenses. Executive agrees that any unvested Incentive Equity in the Company held directly by the Executive shall be automatically forfeited. However, this forfeiture shall not apply if the Executive terminates his employment due to Disability or death.

If the Executive’s employment is terminated due to Disability or death, six (6) additional months of unvested Incentive Equity in the Company held directly by the Executive shall be automatically vested and the remainder of such Incentive

If during the Initial Term the Company terminates the Executive’s employment without Cause (as defined above) or if the Executive terminates his employment with Good Reason (as defined above), and he executes and does not revoke the release of claims attached as Exhibit A so that the release becomes effective in accordance with its terms no later than the sixtieth (60th) day following the date of the Executive’s termination of employment, then, in addition to the payments described in Section 4(a) above, the Executive will receive the following payments and benefits (less all applicable withholdings):

the Executive’s then current Base Salary paid on the Company’s regularly scheduled payroll dates and subject to all applicable withholdings and deductions for six (6) months beginning 60 days after the Termination Date; and the Executive’s prorated Annual Bonus;

if the Executive is eligible for and timely elects continuation coverage under the Company’s group health plan pursuant to the Consolidated Omnibus Budget Reconciliation Act (“COBRA”), then the Company will reimburse Executive for COBRA premiums the Executive pays towards the cost of such continuation coverage for the Executive and the Executive’s eligible dependents (less all applicable tax withholdings) for up to six (6) months of COBRA premiums, or if less, up to the number of months the Executive and his dependents, as applicable, are eligible for such continuation coverage, with such reimbursements to be paid to Executive within thirty (30) days of Executive submitting to the Company such expense for reimbursement under and subject to the Company’s normal expense reimbursement procedures, and provided that Executive submits his reimbursement to the Company within thirty (30) days of payment of such COBRA premium. The Executive understands that obtaining medical insurance coverage through these means will be solely his responsibility, and nothing express or implied in this Agreement creates any obligation on the part of the Executive to enroll in medical coverage as a condition to receiving such payment; and

The Executive shall, upon reasonable notice, furnish the Company with such information as may be in the Executive’s possession or control, and cooperate with the Company, as the Company may reasonably request (with due consideration to

During the Executive’s employment and for six (6) months after termination of employment, the Executive will not directly or indirectly, on behalf of himself or in conjunction with any other person or entity:

own any business (other than less than 2% ownership in a publicly traded company) that sells Competing Products in the Restricted Territory; or

work in the Restricted Territory for any person or entity that sells Competing Products in any role: (i) that is similar to any position held with the Company during the twenty-four (24) months preceding the termination of the Executive’s employment, or (ii) that may cause the Executive to inevitably rely upon or disclose the Company’s Confidential Information.

During the Executive’s employment with the Company and for six (6) months after termination of the Executive’s employment with the Company, the Executive will not directly or indirectly, on behalf of himself or in conjunction with any other person or entity:

solicit business from any customer or prospective customer of the Company with whom the Executive had material contact during the last twenty-four (24) months of employment, if the products or services that customer intends to purchase are similar to products or services offered by the Company;

solicit any employee or independent contractor of the Company who worked for the Company during the six (6) months preceding termination of the Executive’s employment to work for the Executive or the Executive’s new employer.

Assignment of Inventions. The Executive agrees that all right, title, and interest in and to any and all original works of authorship, copyrightable material, concepts, notes, records, drawings, designs, inventions, improvements, developments, discoveries, methods, trademarks, trade names, trade secrets and software (whether or not patentable or registrable under copyright, trademark or similar laws) conceived, discovered, authored, invented, developed or reduced to practice by the Executive, solely or in collaboration with others, during the period of his employment with the Company and related to the business of the Company, or with the use of the Company’s equipment, supplies, facilities, or Company Confidential Information and any and all copyrights, patents, trade secrets, or other intellectual property rights (and related goodwill) relating to the foregoing (collectively, “Inventions”) shall be the sole and exclusive property of the Company. The Executive agrees to promptly make full written disclosure to the Company of any Inventions and to deliver and irrevocably assign fully to the Company all of the Executive’s title and interest in and to all Inventions. The Executive agrees that this assignment of Inventions includes a present conveyance to the Company of ownership of Inventions that are not yet in existence.

Work Made for Hire. The Executive acknowledges that, by reason of being employed by the Company, all of the Inventions are, to the extent permitted by law, “work made for hire” as that term is defined in the United States Copyright Act and are the property of the Company. To the extent that any Inventions are not “work made for hire,” the Executive hereby irrevocably assigns to the Company, for no additional consideration, his entire right, title and interest in and to all Inventions therein. The Executive understands and agrees that the decision whether or not to commercialize or market any Inventions is within the Company’s sole discretion and for the Company’s sole benefit, and that no royalty or other consideration will be due to the Executive as a result of the Company’s efforts to commercialize or market any such Inventions.

Maintenance of Records. The Executive agrees to keep and maintain adequate and current written records of all Inventions made by the Executive (solely or jointly with others) during the term of his employment with the Company. The records may be in the form of notes, sketches, drawings, flow charts, electronic data or recordings, laboratory notebooks, or in any other format. The records will be available to and remain the sole property of the Company at all times. The Executive agrees not to remove such records or any other Confidential Information from the Company’s place of business except as expressly permitted by Company policy which may, from time to time, be revised at the sole election of the Company for the purpose of furthering the Company’s business. The Executive agrees to return all such records (including any copies thereof) to the Company at the time of termination of his employment relationship with the Company or at any time when requested by the Company unless otherwise directed by the Company in writing to destroy such records.

Further Assurances. During and after employment with the Company, the Executive agrees to assist the Company, or its designee, at the Company’s expense, in every proper way to secure the Company’s rights in the Inventions in any and all countries, including the disclosure to the Company of all pertinent information and data with respect thereto, the execution of all applications, specifications, oaths, assignments, and all other instruments that the Company shall deem proper or necessary in order to apply for, register, obtain, maintain, defend, and/or enforce such rights, and in order to deliver, assign and convey to the Company, its successors, assigns, and nominees the sole and exclusive right, title, and interest in and to all Inventions. If the Company is unable for any reason to secure the Executive’s execution of any instrument or papers to apply for or to pursue any application for any United States or foreign patents, copyright or trademark registrations, or other protection of any Inventions, then the Executive irrevocably designates and appoints the Company and its duly authorized officers and agents as his agent and attorney in fact, to act for and in the Executive’s behalf and stead to execute and file any instruments and papers related to such applications and to do all other lawfully permitted acts to further the prosecution and issuance of letters patent, copyright or trademark registrations or other protection of Inventions thereon with the same legal force and effect as if executed by the Executive. The power of attorney is coupled with an interest and shall not be affected by the Executive’s subsequent incapacity.

No Limitations. The Executive represents and warrants that the Executive is not a party to any agreements which would limit the Executive’s ability to assign the Inventions or any related intellectual property rights as required by this Section 7.

Inventions Retained and Licensed. The Executive has attached hereto, as Exhibit B, a list describing with particularity all inventions, original works of authorship, developments, trade secrets and improvements made by the Executive prior to the commencement of his employment with the Company (collectively referred to as “Prior Inventions”), which (i) belong solely to the Executive or belong to the Executive jointly with another, (ii) relate in any way to the Company’s business, and (iii) are not assigned to the Company hereunder (“Prior Inventions”). If no such list is provided, the Executive represents and warrants that the Executive has no rights or interests in or to the Prior Inventions. The Executive further represents and warrants that if any Prior Inventions are included on Exhibit B, those Inventions will not materially affect the Executive’s ability to perform all obligations under this Agreement. The Executive shall inform the Company in writing before incorporating such Prior Inventions into any Inventions or otherwise utilizing such Prior Inventions in the course of the Executive’s employment with the Company, and the Company is hereby granted a nonexclusive, royalty-free, perpetual, irrevocable, transferable worldwide license (with the right to grant and authorize sublicenses) to make, have made, use, import, offer for sale, sell, reproduce, distribute, modify, adapt, prepare derivative works of, display, perform, and otherwise exploit such Prior Inventions, without restriction, including, without limitation, as part of or in connection with such Inventions, and to practice any method related thereto. The Executive will not incorporate any invention, improvement, development, concept, discovery, work of authorship or other proprietary information owned by any third party into any Inventions without the Company’s prior written permission.

Exception to Assignments. The Executive understands that the provisions of this Agreement requiring assignment of Inventions to the Company do not apply to any invention which qualifies fully under the provisions of the Illinois Employee Patent Act 765 ILCS 1060 et seq. The Executive will advise the Company promptly in writing of any inventions that the Executive believes meet the criteria in Illinois Employee Patent Act 765 ILCS 1060 et seq. The Executive acknowledges the statement set forth below:

No amount payable pursuant to this Agreement on account of the Executive’s termination of employment with the Company which constitutes a “deferral of compensation” within the meaning of Section 409A shall be paid unless and until the Executive has incurred a “separation from service” within the meaning of Section 409A. If the Executive incurs a termination of employment that does not constitute a “separation from service” within the meaning of Section 409A, then

The Company and the Executive intend that any right of the Executive to receive installment payments hereunder shall, for all purposes of Section 409A, be treated as a right to a series of separate payments.

With regard to any provision of this Agreement that provides for reimbursement of expenses or in-kind benefits, except for any expense, reimbursement or in-kind benefit provided pursuant to this Agreement that does not constitute a “deferral of compensation,” within the meaning of Section 409A, (i) the right to reimbursement or in-kind benefits shall not be subject to liquidation or exchange for another benefit, (ii) the amount of expenses eligible for reimbursement, or in- kind benefits provided, during any taxable year shall not affect the expenses eligible for reimbursement, or in-kind benefits to be provided, in any other taxable year, provided that the foregoing clause (iii) shall not be deemed to be violated with regard to expenses reimbursed under any arrangement covered by Section 105(b) of the Code solely because such expenses are subject to a limit related to the period the arrangement is in effect, and (iv) such payments shall be made on or before the last day of the Executive’s taxable year following the taxable year in which the expense occurred.

For the purposes of determining when payments may commence after the Executive executes a release in accordance with Section 4 of this Agreement, if the sixtieth (60th) day after the date of termination occurs in the calendar year following the year in which the termination occurs, then no payments or benefits subject to Section 409A shall be paid prior to the first day of such following calendar year, regardless of when the release is executed.
