The Parties intend for the express terms and conditions contained in this Agreement (including any Exhibit and Appendices hereto) and in any subsequently issued Purchase Order to exclusively govern and control each of the Parties' respective rights and obligations regarding the Project and the Parties' agreement is expressly limited to such terms and conditions. Notwithstanding the foregoing, and except with respect to the provisions set forth in Appendix A (Government Flow Downs), if any terms and conditions contained in an invoice, or other communication conflict with any terms and conditions contained in this Agreement, the applicable term or condition of this Agreement or a Purchase Order will prevail and such contrary or different terms will have no force or effect. The terms and conditions of all Purchase Orders are incorporated by reference into this Agreement for all applicable purposes hereunder. Without limitation of anything contained in this Section 2.2, any additional, contrary, or different terms contained in any Confirmation or any of ACRO's invoices or other communications, and any other attempt to modify, supersede, supplement or otherwise alter this Agreement, are deemed rejected by HI-POWER and will not modify this Agreement or be binding on the Parties unless such terms have been fully approved in a signed writing by an Executive Officer of both Parties. 2.3 Purchase Orders. HI-POWER may issue to ACRO one or more Purchase Order(s) for Equipment or Services as provided, herein, each of which shall be incorporated by this reference. HI-POWER shall issue Purchase Orders (containing applicable Basic Purchase Order Terms that are consistent with the terms of this Agreement) to ACRO in written or electronic. By issuing a Purchase Order to ACRO, HI-POWER makes an offer to purchase Equipment, an Automated System(s) and/or Services, as applicable, pursuant to the terms and conditions of this Agreement and the Basic Purchase Order Terms contained in the Purchase Order. For the avoidance of doubt, HI- POWER shall only be obligated to purchase from ACRO, and ACRO shall be obligated to sell to HI-POWER, the Equipment, the Automated System(s) and Services specified in the Initial Order described on Exhibit A or in an accepted Purchase Order. 2.4 Acceptance, Rejection, and Cancellation of Purchase Orders. ACRO shall confirm to HI- POWER the receipt of each Purchase Order issued hereunder (each, a "Confirmation") within five (5) Business Days following ACRO's receipt thereof in written form. Each Confirmation must reference HI-POWER's Purchase Order number, confirm acceptance of the Purchase Order or advise HI-POWER of ACRO's rejection of such Purchase Order (but only solely if permitted under this Section 2.4), the date of acceptance or rejection, and the basis for rejection (if applicable). If ACRO fails to issue a Confirmation within the time set forth in the first sentence of this Section 2.4 or otherwise commences performance under such Purchase Order, ACRO will be deemed to have accepted the Purchase Order. HI-POWER may withdraw any Purchase Order prior to ▇▇▇▇'s acceptance thereof. ACRO may only reject a Purchase Order if: (a) HI-POWER has sent ACRO a notice of termination under Section 14.4 or Section 14.5; or (b) the applicable Purchase Order includes terms and conditions that supplement those contained in this Agreement, which

10 ACRO is unwilling to accept. ACRO may not cancel any previously accepted Purchase Order hereunder. To the extent ACRO is unable to provide the requested Equipment or Work under any Purchase Order issued and accepted hereunder, ACRO shall be in breach of this Agreement. In the event of such breach, and without limiting HI-POWER's other remedies available hereunder under Applicable Laws, HI-POWER shall be entitled to recover all additional costs of purchasing replacement or cover Equipment, Automated Systems and Work for the Project. 2.5 Changes. Any Change to a Purchase Order must be authorized in accordance with Article 9. 2.6 Term. (a) Initial Term.

(b) Renewal Term. Upon expiration of the Initial Term, the term of this Agreement will automatically renew for up to three (3) additional successive one (1) year terms unless both Parties provides written notice of non-renewal at least one-hundred eighty (180) days prior to the end of the then-current term (each, a "Renewal Term" and together with the Initial Term, the "Term"), unless any Renewal Term is earlier terminated pursuant to the terms of this Agreement or Applicable Law. If the Initial Term or any Renewal Term is renewed for any Renewal Term(s) pursuant to this Section 2.6(b), the terms and conditions of this Agreement during each such Renewal Term will be the same as the terms in effect immediately prior to such renewal. In the event both Parties provide timely notice of their intent not to renew this Agreement, then, unless earlier terminated in accordance with its terms, this Agreement terminates on the expiration of the Initial Term or then-current Renewal Term, as applicable. (c) Effect Upon Expiration. For the avoidance of doubt, termination or expiration of this Agreement shall not affect the validity of any Purchase Orders previously issued and accepted, and the terms and conditions of this Agreement shall remain in full force and effect so long as any Work or payment obligations under a Purchase Order is not completed. 2.7 No Right to Manufacture and Sell Similar Products.

ARTICLE 3. PRICE AND PAYMENT 3.1 Price. During the Term, ACRO agrees to be bound by the prices set forth in Exhibit A (Scope of Supply) for the initial Equipment and performance of the applicable Services (the "Initial Order"). The Price of the Initial Order is set forth on Exhibit A (Scope of Supply). HI-POWER may place one or more additional Purchase Orders for Equipment and Work with respect to the Automated Systems from ACRO, at the prices set forth in a Purchase Order. All Prices contained in the Exhibit A (Scope of Supply) or any Purchase Order are firm and are not subject to increase for any reason, including changes in market conditions, increases in raw material, component, labor, or overhead costs or because of labor disruptions or fluctuations in production volumes. ACRO understands that HI-POWER has relied upon Exhibit A (Scope of Supply), and will rely upon future Purchase Orders, in its business decisions regarding the Automated Systems, and that a failure by ACRO to comply with Exhibit A (Scope of Supply) or any Purchase Order would cause direct and material damage to HI-POWER and its Affiliates. ACRO represents and warrants to HI-POWER that Exhibit A (Scope of Supply) is inclusive of all of ACRO's costs and expenses associated the terms of this Agreement and the initial Purchase Order issued and accepted hereunder. ACRO acknowledges the material required to manufacture the Automated Systems may be subject to import duties, including without limitation import tariffs when imported to the United States, and expressly assumes all responsibility for payment of such import duties. ACRO assumes all risk of any increase in import duties and/or the imposition of new import duties on such material. The modification of import duties on such material shall not be cause for an ACRO Change Order Request.

11 3.2 Taxes. The Prices are inclusive of any and all Taxes (exclusive of Excluded Taxes) imposed under Applicable Law on ACRO, the Subcontractors, the Work, the Equipment, or HI-POWER with respect to this Agreement or ACRO's performance of the Work. ACRO shall take reasonable steps requested by HI-POWER to minimize the amount of Excluded Taxes. The Parties agree to reasonably cooperate to minimize each Party’s Tax liability to the extent legally permissible, including providing information relating to Taxes as reasonably requested by any Governmental Authority. To the extent any abatements, exemptions, deferrals, or credits against any Taxes may be available to either Party pursuant to Applicable Laws, the Parties shall reasonably cooperate to secure such abatements, exemptions, deferrals, or credits against any Taxes. 3.3 Payments. The Prices shall be paid by HI-POWER to ACRO as follows: (a) Invoicing for Payment.

(b) HI-POWER's Approval of Invoices. No later than seven (7) Business Days following receipt of any invoice in accordance with Section 3.3(a), HI-POWER shall either approve such invoice or notify ACRO in writing of any inaccuracies, missing documentation or of any other reason why the requirements for approval of the invoice has not been met. If HI-POWER notifies ACRO of inaccuracies, missing documentation, or of any other valid reason that the requirements for approval of the invoice have not been met, ACRO shall, promptly cure any inaccuracies, missing documentation or other issues identified by HI-POWER and resubmit a new invoice. (c) Offset. By written notice to ACRO, HI-POWER may deduct and offset against any part of the balance due to ACRO under this Agreement any undisputed amount due from ACRO to HI-POWER under this Agreement. 3.4 Required Submittals. As a condition precedent to HI-POWER's approval of any invoice submitted by ACRO, the following documents shall be submitted with each invoice, except as expressly stated herein: (a) evidence that ACRO has completed all deliverables expressly required to be performed for which payment is requested; (b) for any Work performed pursuant to an Approved Change Order, supporting documentation demonstrating the Direct Costs incurred by ACRO or any Subcontractors in connection with such Approved Change Order; and (c) any other evidence or documentation reasonably requested by HI-POWER to verify ACRO's progress in performing the Work or to verify that ACRO has paid for all services, materials and labor used in connection with the performance of this Agreement through the period covered by payments received from HI- POWER, including but not limited to an unconditional lien waiver in form and substance reasonably satisfactory to HI-POWER, executed by duly authorized officers or representatives of ACRO and any Subcontractor, as applicable. 3.5 No Mechanic’s Lien. ACRO, by entering into this Agreement, agrees to waive its right to file a claim for a mechanic’s lien against the Equipment and Automated Systems, including any attachments. Further, ▇▇▇▇ agrees to obtain from all persons or third-parties with whom it subcontracts, purchases from, or does business with, in the fulfillment of this Agreement, a written waiver of mechanic’s lien in favor of HI-POWER in form and substance reasonably satisfactory to HI-POWER. ACRO will provide HI-POWER with executed copies of this waiver prior to the undertaking of any activity or Work. ACRO, at its sole expense, agrees to indemnify and defend HI- POWER, and hold it harmless from all losses, including legal fees and expenses, arising from ACRO's failure to obtain the mechanic’s lien waivers. In the event ACRO becomes unable, because of insolvency, or bankruptcy, or for any other reason, to timely compensate its Subcontractors, agents, and other entities whose efforts have been obtained by ACRO in the fulfillment of this Agreement, or is otherwise unable to meet its debt obligations, in addition to any other remedies HI-POWER may avail itself of in law or equity, HI-POWER reserves the right to make payments directly to these entities, bankruptcy court, trustees in bankruptcy, or receivers as it deems necessary, subtracting the amount of these payments plus any legal expenses incurred from any sums owed to ACRO under this Agreement. In this event, ACRO waives any right of further recompense from HI-POWER for the work completed by these entities.

All tangible property of every description, including supplies, materials, machinery, equipment, drawings, photographic negatives and positives, artwork, copy layout, electronic data, and other items, furnished by HI-POWER or its Affiliates, either directly or indirectly, to ACRO or to any supplier to ACRO in connection with or related to this Agreement, or for Equipment related to an Automated System which

15 ACRO has been at least partially reimbursed by HI-POWER (collectively, "Bailed Property") is and will at all times remain the property of HI-POWER and be held by ACRO on a bailment-at-will basis. (b) Title to Bailed Property. Only HI-POWER has any right, title, or interest in and to Bailed Property, except for ACRO's limited right, subject to HI-POWER's sole discretion, to use the Bailed Property in the performance of ACRO'S obligations under this Agreement. ACRO shall not use the Bailed Property for any other purpose. ACRO shall not commingle Bailed Property with the property of ACRO or with that of a Person other than HI-POWER or ACRO and shall not move any Bailed Property from ACRO's premises without the prior written approval by HI-POWER. HI-POWER may, at any time, for any reason and without payment of any kind, retake possession of any Bailed Property without the necessity of payment or notice to ACRO, or a hearing or a court order, which rights, if any, are waived by ACRO. Upon HI-POWER'S request, Bailed Property will be immediately released to HI-POWER or delivered to HI-POWER by ACRO. ▇▇▇▇'S continued holding of Bailed Property after demand has been made by HI-POWER for delivery will substantially impair the value thereof, and, accordingly, HI-POWER will be entitled to a court order of possession without any need of proving damages or posting of a bond. To the fullest extent permitted by law, ACRO shall not allow any Lien to be imposed on or attach to the Bailed Property through ACRO or as a result of ACRO's action or inaction, and ACRO hereby waives any Lien that it may have or acquire in the Bailed Property. (c) Bailed Property. ACRO acknowledges and agrees that: (i) HI-POWER is neither the manufacturer of the Bailed Property nor the manufacturer's agent; (ii) HI-POWER is bailing Bailed Property to ACRO for ACRO's benefit; (iii) ACRO has inspected the Bailed Property and is satisfied that the Bailed Property is suitable and fit for its intended purposes, of which ACRO is aware; and (iv) HI-POWER HAS NOT MADE AND DOES NOT MAKE ANY REPRESENTATION OR WARRANTY WHATSOEVER, EITHER EXPRESS OR IMPLIED, AS TO THE FITNESS, CONDITION, MERCHANTABILITY, DESIGN OR OPERATION OF THE BAILED PROPERTY OR ITS FITNESS FOR ANY PARTICULAR PURPOSE. Notwithstanding the foregoing, if the bailment relationship described in this Section 6.1 is deemed to be a secured financing transaction, ACRO grants to HI-POWER a continuing security interest in any rights or interests it may have in the Bailed Property. 6.2 Tooling Orders. (a) ACRO may not charge HI-POWER for the cost of manufacturing or procuring any Tooling or other materials used in the production and sale of the Automated Systems unless HI-POWER agrees in writing to reimburse ACRO for ACRO's actual reasonable costs of manufacturing or procuring such Tooling or other materials (a "Reimbursement Authorization"). Payment for such Tooling or materials will be due only after: (i) HI-POWER has successfully completed all testing of such Tooling or materials required by HI-POWER, which will be conducted at ACRO's sole cost and expense; (ii) HI-POWER has successfully conducted a tooling audit in accordance with its customer's requirements; and (iii) ACRO has provided to HI-POWER detailed invoices documenting the actual costs incurred by ACRO for such Tooling or materials, including copies of any invoice issued to ACRO by any third party with respect thereto, and other any other information reasonably requested by HI-POWER with respect to such Tooling or materials (which may include CAD models and drawings). HI-POWER shall pay ACRO only the actual cost of such Tooling or materials, not to exceed the authorized amount, if any, stated in the applicable Reimbursement Authorization. (b) Such Tooling or other materials that are subject to a Reimbursement Authorization provided by HI-POWER will become Bailed Property (and title thereto will vest in HI-POWER) immediately upon completion of all testing required by HI-POWER (provided that HI-POWER will not be relieved of its obligation to pay for such Tooling or materials in accordance with the terms of this Agreement) or if earlier, any payment by HI- POWER to ACRO therefor. Any payments made by HI-POWER for Bailed Property are expressly intended by HI- POWER to be held in trust for the benefit of any subcontractors or suppliers used by ACRO to fabricate the Bailed Property that relates to such payments, and ACRO agrees to hold such payments as trustee in express trust for such subcontractors or suppliers until ACRO has paid the subcontractors or suppliers in full for the Bailed Property. 6.3 Maintenance; Risk of Loss. ACRO shall bear all risk of loss of and damage to Bailed Property. ACRO shall, at its own expense, for the benefit of HI-POWER, insure all Bailed Property with full and extended coverage for all losses, for its full replacement value, in accordance with the terms of Article 13. As and when it is commercially reasonable to do so, ACRO shall, at its sole cost and expense, maintain, repair, refurbish and replace Bailed Property. All replacement parts, additions, improvements, and accessories for such Bailed Property will

16 automatically become HI-POWER's property upon their incorporation into or attachment to the Bailed Property. All replacements of Bailed Property will also be HI-POWER's property. ACRO shall replace any missing components of or inserts to any Bailed Property. 6.4 Inventory. ACRO will maintain a written inventory of all Bailed Property that sets forth a description and the location of all Bailed Property, and provide a copy of this inventory to HI-POWER upon request. ACRO shall mark all Bailed Property permanently and conspicuously to identify it as the property of HI-POWER, and indicate HI-POWER's name and address.

"Substantial Completion" shall mean, with respect to each Automated System, that all of the following have been achieved by ACRO in accordance with the Requirements (or otherwise waived in writing by HI-POWER in writing): (i) all Site Acceptance Tests have been conducted and the requirements with respect thereto have been satisfied; (ii) the Automated System shall have achieved one-hundred percent (100%) of the expected rate of output under the Requirements, as may be amended in accordance with this Agreement; (iii) the Work complies with all Applicable Laws, and has passed all required inspections by any applicable Governmental Authority, and ACRO has performed all the obligations under this Agreement to achieve Substantial Completion; (iv) HI-POWER and ACRO have agreed on a Substantial Completion Punchlist in accordance with Section 7.6(d)(i); (v) Delay Liquidated Damages accruing and then-unpaid by ACRO to HI-POWER in connection with any Guaranteed Milestone (or any prior Guaranteed Milestone) as of the date that ACRO submits the Notice of Substantial Completion have been paid, unless the next payment would require HI-POWER to pay ACRO an amount greater than any then unpaid Delay Liquidated Damages, then HI-POWER will offset such amount against the next payment, all in accordance with Section 7.8(b); and (vi) HI-POWER has delivered a Substantial Completion Certificate as provided in Section 7.6(c). (b) Notice of Substantial Completion. When ACRO has satisfied the requirements for Substantial Completion of an Automated System, ACRO shall deliver a written notice, signed by an authorized representative of ACRO, certifying such completion to HI-POWER and containing a report with sufficient detail to enable HI-POWER to determine whether ACRO has satisfied such requirements, including a certification of the Site Acceptance Test report received by ACRO from HI-POWER or the results of any Inspections, as applicable, along with a list of any unresolved Defects, that do not qualify as Punchlist Items, in the Work of which ACRO is aware and the status of correction of such Defects, and shall also contain a certification that all ACRO Change Order Requests or HI-POWER Change Requests have been resolved other than those pending ACRO Change Order Requests listed therein (the "Notice of Substantial Completion"). (c) Substantial Completion Certificate. Within ten (10) Business Days after receipt by HI- POWER of the Notice of Substantial Completion (and all required submittals), HI-POWER shall either (i) deliver to ACRO a certificate in form and substance reasonably satisfactory to HI-POWER identifying the Substantial Completion Date (the "Substantial Completion Certificate") or (ii) advise ACRO in writing of any reason why the requirements of Substantial Completion have not been met (including missing substantiating information). If HI- POWER accepts that such requirements have been met, then the date that ACRO submitted the Notice of Substantial Completion that is ultimately accepted by HI-POWER shall be deemed to be the Substantial Completion Date, and such date shall be noted on the Substantial Completion Certificate. Upon receipt of any notice from HI-POWER of outstanding requirements to be completed by ACRO according to this Agreement, ACRO shall promptly complete such requirements, and the notice procedure set out in Section 7.6(b) and this Section 7.6(c) shall be repeated until the requirements for Substantial Completion have been met and the Substantial Completion Certificate has been delivered by HI-POWER.

19 (d) Substantial Completion Punchlist. (i) No later than ten (10) days prior to the date ACRO expects to achieve Substantial Completion, ACRO shall prepare and deliver to HI-POWER a proposed list of Punchlist Items, if any, the proposed schedule within which ACRO shall complete each such Punchlist Item, and an estimated cost to complete each Punchlist Item thereon. Upon its receipt of ACRO's prepared list of such items, (A) HI-POWER shall review such list, (B) at HI-POWER's request, HI-POWER and ACRO shall perform a walk-down of the Automated System, and (C) within three (3) Business Days after receipt by HI-POWER of such proposed list of Punchlist Items, HI-POWER shall notify ACRO in writing of either its acceptance of the list of Punchlist Items or rejection of the list of Punchlist Items; provided, that HI-POWER may only reject the list if (i) the list contains items that do not meet the definition of "Punchlist Items", and (ii) HI-POWER provide reasonable detail as to the basis for such rejection. If HI-POWER directs ACRO to make any appropriate or necessary revisions to same (including removal of items of Work that do not meet the definition of Punchlist Items), ACRO shall promptly correct the proposed list of Punchlist Items and shall issue a revised list to HI-POWER within five (5) days after ACRO's receipt of the comments. If HI-POWER does not accept the list of Punchlist Items in writing within three (3) Business Days following ACRO's resubmission, HI- POWER's Representative or other individual designated by HI-POWER and the Project Manager shall meet and consult in good faith to agree upon the definitive list of Punchlist Items, including items to be performed and a scheduled date of completion for each such item, which information shall be attached to the Substantial Completion Certificate. The list of Punchlist Items that has been agreed upon by HI-POWER and ACRO under this Section shall be the "Substantial Completion Punchlist". (ii) Once the Substantial Completion Punchlist is agreed upon by HI-POWER and ACRO, ACRO shall immediately begin performing the Punchlist Items on the Substantial Completion Punchlist and complete such Punchlist Items on or before the date set forth in the Substantial Completion Punchlist; provided, however, that if ACRO has not commenced performance of such items within thirty (30) days following agreement on the Substantial Completion Punchlist, or has not completed any Punchlist Items on the Substantial Completion Punchlist within the schedule provided therein, HI-POWER shall have the right in its discretion (but not the obligation) to perform or procure the performance of such items at ACRO's expense and offset such expense against any remaining payments due to ACRO. The performance of any Punchlist Item on the Substantial Completion Punchlist by HI- POWER: (A) shall not relieve ACRO of its obligations under this Agreement for one hundred percent (100%) of the Work to be complete in order to achieve Final Acceptance; (B) shall not relieve ACRO of any other obligations under Applicable Laws or under this Agreement or constitute a waiver of any of HI-POWER's rights; and (C) shall not relieve ACRO of its obligation to reimburse HI-POWER for all reasonable and documented Direct Costs incurred by HI-POWER to complete or have completed the Punchlist Items should such amounts exceed amounts that can be withheld and offset by HI-POWER against amounts due to ACRO under this Agreement. In completing the Punchlist Items, ACRO shall not unreasonably interfere with HI-POWER's use and operation of the Automated System or the Project. 7.7 Final Acceptance. (a) Final Acceptance of the Work. "Final Acceptance" shall mean, with respect to each Automated System, that all of the following have been achieved by ACRO in accordance with the Requirements (or otherwise waived in writing by HI-POWER): (i) Substantial Completion has occurred and all conditions thereto continue to be satisfied; (ii) ACRO has completed all hand-off activities for the Automated System; (iii) HI-POWER has received from ACRO and each Subcontractor final lien waivers in form and substance reasonably satisfactory to HI-POWER with respect to the Work or the performance of any services or delivery of any materials that could result in a lien on the Site, the Project, or the Automated System; (iv) all Punchlist Items on the Substantial Completion Punchlist for the Automated System have been completed to HI-POWER's reasonable satisfaction;

20 (v) any then current Defects or other Warranty claims have been corrected and resolved to HI-POWER’s reasonable satisfaction; (vi) ACRO has paid all Delay Liquidated Damages (if any), due under this Agreement; (vii) ACRO has Demobilized; and (viii) HI-POWER has delivered a Final Acceptance Certificate with respect to the Automated System as provided in Section 7.7(c). (b) Notice of Final Acceptance. When ACRO has satisfied the requirements for Final Acceptance (other than Section 7.7(a)(viii)), ACRO shall deliver a written notice, signed by an authorized representative of ACRO, certifying such completion to HI-POWER and containing a report with sufficient detail to enable HI-POWER to determine whether ACRO has satisfied such requirements, and shall also contain a certification that all ACRO Change Order Requests or HI-POWER Change Requests have been resolved and ACRO has no claims against HI-POWER for payment of the Contract Price (except the amounts to be paid in connection with Final Acceptance) or for Changes in the Work, except for disputes formally brought under Section 18.3 as of such date (the "Notice of Final Acceptance"). (c) Final Acceptance Certificate. Within ten (10) Business Days after receipt by HI-POWER of the Notice of Final Acceptance (and all required submittals), HI-POWER shall either (i) deliver to ACRO a certificate in form and substance reasonably satisfactory to HI-POWER identifying the Final Acceptance Date (the "Final Acceptance Certificate") or (ii) advise ACRO in writing of any reason why the requirements of Final Acceptance have not been met (including missing substantiating information). If HI-POWER accepts that such requirements have been met, then the date that ACRO submitted the Notice of Final Acceptance that is ultimately accepted by HI-POWER shall be deemed to be the Final Acceptance Date, and such date shall be noted on the Final Acceptance Certificate. Upon receipt of any notice from HI-POWER of outstanding requirements to be completed by ACRO according to this Agreement, ACRO shall promptly complete such requirements, and the notice procedure set out in Section 7.7(b) and this Section 7.7(c) shall be repeated until the requirements for Final Acceptance have been met and the Final Acceptance Certificate has been delivered by HI-POWER. (d) Demobilization. Unless otherwise directed by HI-POWER in writing, ACRO shall be solely responsible for Demobilization and the removal from the Site and disposal of any equipment not incorporated into the Work following Substantial Completion and which are not spare parts or are otherwise unnecessary for the completion of any Substantial Completion Punchlist items or otherwise required for achievement of Final Acceptance. 7.8 Delay Liquidated Damages. (a) Delay Liquidated Damages. If ACRO fails to achieve any of the Guaranteed Milestones on or before the applicable date, then ACRO shall pay HI-POWER, as liquidated damages and not as a penalty, an amount as set forth in the applicable Purchase Order, with respect to such delay in achieving the Guaranteed Milestone (collectively, the "Delay Liquidated Damages") for each day from and after the applicable date, until the achievement of the Guaranteed Milestone. For the avoidance of doubt, completion of each Guaranteed Milestone on or before the applicable date is a separate and independent guaranty, and ACRO will accrue liability for Delay Liquidated Damages on a cumulative basis for any and all Guaranteed Milestones that are not achieved on or prior to the applicable dates. (b) Payments. Delay Liquidated Damages shall accrue on a daily basis, and ACRO shall pay or HI-POWER will offset Delay Liquidated Damages accruing and then-unpaid with respect to each Guaranteed Milestone concurrent with the due date for the next payment under this Agreement. Notwithstanding anything to the contrary, if the next payment would require HI-POWER to pay ACRO an amount greater than the accrued Delay Liquidated Damages, then HI-POWER will offset such amount against the next progress payment. (c) Delay Liquidated Damages Not a Penalty. The Parties agree that it would be extremely difficult to precisely determine the amount of actual damages that would be suffered by HI-POWER as a result of a delay in achieving the Guaranteed Milestones, but that the Delay Liquidated Damages are a fair and reasonable determination of the amount of actual damages that would be suffered by HI-POWER for delays beyond the applicable dates, and that the Delay Liquidated Damages do not constitute a penalty. It is further understood and agreed between

21 the Parties that: (i) HI-POWER would be damaged in the event that ACRO failed to meet any of the Guaranteed Milestones by the respective dates; (ii) the Delay Liquidated Damages are fair and reasonable considering the damages that HI-POWER would sustain in the event ACRO fails to achieve any Guaranteed Milestone by the respective dates, (iii) except for the remedies of HI-POWER and the liability of ACRO flowing from HI-POWER's exercise of any remedies set forth in Article 14 with respect to a ACRO Event of Default set out in Section 12.2, each with respect to an extended failure to meet any Guaranteed Milestone, payment of Delay Liquidated Damages shall be HI-POWER's sole and exclusive remedy and ACRO's sole and exclusive liability for its failure to achieve the Guaranteed Milestones by the applicable dates. ARTICLE 8. TITLE; LOSS OR DAMAGE; FORCE MAJEURE 8.1 Title and Risk of Loss. (a) Title to Supplies and Components. Title to the supplies and other components of the Work provided by ACRO shall pass to HI-POWER upon the earlier: of (i) the date payment for such supplies or components is received by ACRO, or (ii) the date any such items are delivered to the Site, provided that, ACRO and its Subcontractors do not thereby waive or release their mechanic’s lien or other materialman’s lien rights and retaining such rights is not a breach of the obligation to transfer title. (b) Title to Automated Systems. Title to an Automated System shipped under any Purchase Order passes to HI-POWER upon the earliest to occur of (i) delivery of the Automated System to HI-POWER; (ii) payment of any portion of the Price for such Automated System by HI-POWER, and (iii) HI-POWER's acceptance of the Automated System. Goods will be deemed identified upon ▇▇▇▇’s commencement of production. Title will transfer to HI-POWER even if HI-POWER has not been paid for such Line, provided that HI-POWER will not be relieved of its obligation to pay for the Automated System in accordance with the terms hereof. (c) Risk of Loss. ACRO shall retain care, custody and control and risk of loss of all components of the Work until the Substantial Completion Date, at which time risk of loss to such components of the Work shall pass to HI-POWER. Notwithstanding the transfer of risk of loss to HI-POWER, ACRO shall nevertheless remain liable for any loss or damage to the Work to the extent caused in whole or in part by ACRO or any other ACRO Responsible Party, subject to Article 13. If any loss or damage occurs to the Work following the transfer to HI- POWER of care, custody and control and risk of loss, then ACRO shall replace or repair any such loss or damage and complete the Work in accordance with this Agreement at the sole cost and expense of HI-POWER (subject to Article 13) and with an Approved Change Order (unless such loss or damage was caused by any ACRO Responsible Party, in which case ACRO shall complete the Work at its expense, subject to Article 13. 8.2 Force Majeure.

With respect to each Automated System, ACRO warrants and guarantees to HI-POWER that, for the period commencing on the Final Acceptance Date of the Automated System and continuing until the date that is one (1) year after the Final Acceptance Date of the Automated System (the "Workmanship Warranty Period"), all aspects of the Work shall be: (i) performed in a good and workmanlike manner and in accordance with Prudent Industry Standards and all other Requirements; (ii) conducted to ensure that no exclusions or limitations to any manufacturer’s warranty of any component of the Work shall apply; and (iii) constructed to satisfy all Requirements. Any such Work that fails to satisfy the Warranty set forth in this Section 11.1(b) is referred to herein as a "Workmanship Defect". The Workmanship Warranty Period shall be extended with respect to any Workmanship Defect for which ACRO performs Warranty Services to the date that is the later of: (A) is two (2) years after the Final Acceptance Date of the Automated System; or (B) twelve (12) months after ACRO completes such Warranty Service. 11.2 Warranty Liquidated Damages. (a) Warranty Liquidated Damages. If there is a breach of any Warranty during the Warranty Period, then ACRO shall pay HI-POWER, as liquidated damages and not as a penalty, an amount as set forth in the applicable Purchase Order (collectively, the "Warranty Liquidated Damages") for each day from and after any breach of Warranty until the Warranty Service is completed. For the avoidance of doubt, completion of each Warranty Service is a separate and independent guaranty, and ACRO will accrue liability for Warranty Liquidated Damages on a cumulative basis for any and necessary additional Warranty Services. (b) Payments. Warranty Liquidated Damages shall accrue on a daily basis, and ACRO shall pay or HI-POWER will offset Warranty Liquidated Damages accruing and then-unpaid with respect to each Warranty Service concurrent with the due date for the next payment under this Agreement. Notwithstanding anything to the contrary, if the next payment would require HI-POWER to pay ACRO an amount greater than the accrued Warranty Liquidated Damages, then HI-POWER will offset such amount against the next payment. (c) Warranty Liquidated Damages Not a Penalty. The Parties agree that it would be extremely difficult to precisely determine the amount of actual damages that would be suffered by HI-POWER as a result of breach of Warranty, but that the Warranty Liquidated Damages are a fair and reasonable determination of the amount of actual damages that would be suffered by HI-POWER reduced expected rate of output of an Automated System, and that the Delay Liquidated Damages do not constitute a penalty. It is further understood and agreed between the Parties that: (i) HI-POWER would be damaged in the event of a breach of Warranty; (ii) the Warranty Liquidated Damages are fair and reasonable considering the damages that HI-POWER would sustain in the event ACRO fails to deliver an Automated System that maintains the expected rate of output during the Warranty Period, (iii) except for the remedies of HI-POWER and the liability of ACRO flowing from HI-POWER's exercise of any remedies set forth in Article 14 with respect to a ACRO Event of Default set out in Section 12.2, each with respect to a breach of Warranty, payment of Warranty Liquidated Damages shall be HI-POWER's sole and exclusive remedy and ACRO's sole and exclusive liability for its failure for breach of Warranty. 11.3 Remedies Under Warranties. If any Warranty is breached during the Warranty Period, HI- POWER shall provide written notice to ACRO. So long as ACRO has been notified by HI-POWER of a breach of Warranty within the Warranty Period, the obligation of ACRO to provide Warranty Service shall survive expiration of the relevant Warranty Period. ACRO shall perform all Work, supply all materials necessary, and bear all costs arising from or relating to the correction and remediation of such breach (such actions, collectively the "Warranty Service"). ACRO and ACRO Responsible Parties performing on its behalf shall conduct all activities pursuant to this Section 11.3 in a manner that ensures the minimum possible interference with the Project's performance, availability and functionality and will coordinate with HI-POWER as to the time of day that Warranty Service is provided, including providing Warranty Service when the Site is not generating, curtailed, or minimally generating power and providing ancillary services. Subject to the prior sentence, ACRO shall have reasonable access to the Site as necessary

26 to perform its Warranty obligations under this Agreement. Should ACRO fail to commence performance of Warranty Service or its other obligations under this Section 11.3 within five (5) Business Days of receipt HI-POWER’s valid Warranty claim provided hereunder and thereafter diligently pursue the performance of its obligations, HI-POWER shall have the right in its sole discretion to perform (or engage a Third Party to perform) such obligations, and ACRO shall be liable for all Direct Costs incurred by HI-POWER arising from the performance of ACRO's obligations. ACRO's payment of any amount owing to HI-POWER pursuant to this Section 11.3 shall be due no later than thirty (30) days following HI-POWER’s submission of an invoice for such Direct Costs to ACRO. Any late delivery of such payments shall bear interest at the Interest Rate. HI-POWER’s action in correcting Workmanship Defect in accordance with this Section 11.3 shall not void, offset, or relieve any other obligations of ACRO under this Agreement, including ACRO's Warranty obligations. The obligations of ACRO pursuant to this Section 11.3 are in addition to, and not in lieu of, the indemnity obligations of ACRO under Article 12. 11.4 Long Term Service Agreement. The Parties agree that HI-POWER will have an option to execute an extended service, maintenance, monitoring, and performance guarantee of the Automated Systems upon payment of an additional fee and on the terms and conditions as shall be agreed by the Parties in a separately executed long- term service agreement ("LTSA"). ARTICLE 12. INDEMNIFICATION 12.1 Indemnification. Subject to the terms and conditions of this Agreement, ACRO (as “Indemnifying Party”) shall indemnify, reimburse, defend and hold harmless HI-POWER, its Affiliates and its and their Representatives successors and permitted assigns (each, an “Indemnified Party”) against any and all losses, damages, liabilities, deficiencies, claims, actions, judgments, settlements, interest, awards, penalties, fines, costs, or expenses of whatever kind, including reasonable attorneys' fees, fees and the costs of enforcing any right to indemnification under this Agreement and the cost of pursuing any insurance providers, incurred by any Indemnified Party (collectively, "Losses"), relating to, arising out or resulting from any claim alleging: (a) a breach or non-fulfillment of any of Indemnifying Party’s representations, warranties, or covenants set forth in this Agreement; (b) any negligent, reckless, or willful act or omission of Indemnifying Party or any of its Representatives or Subcontractors in connection with Indemnifying Party’s performance under this Agreement; (c) any bodily injury, death of any Person or damage to real or tangible personal property caused by the acts or omissions of Indemnifying Party or any of its Representatives or Subcontractors; (d) any failure by Indemnifying Party or its Personnel, including for the avoidance of doubt Subcontractors, to comply with any Applicable Laws; or (e) that any of Indemnifying Party’s Intellectual Property used in the design or production of the Automated Systems, or that is embodied in the Automated Systems, infringes any Intellectual Property rights of a Third Party. 12.2 Exceptions to Indemnification. Notwithstanding anything to the contrary in this Agreement, Indemnifying Party is not obligated to indemnify or defend any Indemnified Party to the extent a claim brought under this Article 11 or corresponding Losses results directly from, in whole or in part, Indemnified Party's or its Personnel's: (a) gross negligence or more culpable act or omission (including recklessness or willful misconduct); or (b) failure to materially comply with any of its obligations set forth in this Agreement. 12.3 Limitations of Liability. IN NO EVENT SHALL EITHER PARTY OR ITS REPRESENTATIVES BE LIABLE FOR CONSEQUENTIAL, INDIRECT, INCIDENTAL, SPECIAL, EXEMPLARY, PUNITIVE OR ENHANCED DAMAGES, LOST PROFITS OR REVENUES OR

27 DIMINUTION IN VALUE, ARISING OUT OF OR RELATING TO ANY BREACH OF THIS AGREEMENT, REGARDLESS OF (A) WHETHER SUCH DAMAGES WERE FORESEEABLE, (B) WHETHER OR NOT HI-POWER WAS ADVISED OF THE POSSIBILITY OF SUCH DAMAGES AND (C) THE LEGAL OR EQUITABLE THEORY (CONTRACT, TORT OR OTHERWISE) UPON WHICH THE CLAIM IS BASED, AND NOTWITHSTANDING THE FAILURE OF ANY AGREED OR OTHER REMEDY OF ITS ESSENTIAL PURPOSE. ARTICLE 13. INSURANCE 13.1 ACRO Insurance Requirements. During the Term and for so long thereafter as ACRO may have indemnification liability under this Agreement, ACRO shall maintain and keep in force, at its own expense, the following minimum insurance coverages and minimum limits: (a) Workers’ Compensation Insurance providing statutory benefits and Employer’s Liability Insurance with limits of not less than those limits that are required by Applicable Laws. (b) Comprehensive Commercial General Liability Insurance covering claims for bodily injury, death, and property damage, including Premises and Operations, Independent Suppliers, Product and Completed Operations, Personal Injury, Contractual Liability, Fire, Legal Liability, Product Liability Coverage, and Broad form Property Damage liability coverages, with limits as follows: Occurrence/Aggregate Limit of $5 million for bodily injury, death, and property damage, each occurrence, and $10 million general aggregate. (c) Umbrella insurance coverage with an aggregate limit of no less than $10 million; (d) Automobile Liability, $1,000,000.00 per occurrence combined single limit BI/PD; and (e) Unless otherwise instructed by HI-POWER, ACRO shall fully insure any bailed property and the insurance policy shall be in form and in an amount equivalent to the current replacement value and reasonably acceptable to HI-POWER, and shall name HI-POWER as an additional insured and loss payee. ACRO shall deliver to HI-POWER upon HI-POWER’s request the policies of insurance or duplicates thereof or other evidence satisfactory to HI-POWER of the insurance coverage. Each insurer must give HI-POWER 30 days’ prior written notice of the effective date of any alteration or cancellation of coverage. If ACRO fails to obtain such insurance, HI-POWER shall have the right to obtain insurance at ACRO’s expense. In the event ACRO fails to procure and maintain insurance as provided herein, HI-POWER may take whatever steps are necessary to carry out these requirements. 13.2 Evidence of Coverage. ACRO shall provide HI-POWER with a proper certificate of insurance from its insurance carrier prior to commencing performance of the Services. HI-POWER shall be included on the certificate as an additional insured and loss payee with respect to all insurance required by this Agreement (excluding Worker’s Compensation) and shall contain endorsements stating that the policies are primary and not excess over or contributory with any other valid, applicable, and collectible insurance in force for HI-POWER. ACRO shall also provide HI-POWER with certificates of the above described insurance obtained by its subcontractors and suppliers. HI-POWER’s failure to request a copy of the certificate of insurance shall not be considered to be a waiver of ACRO’s obligation to procure and maintain such insurance. 13.3 Cancellation. Each insurance policy shall contain a clause that states that the policy shall not be cancelled by the insurance company without thirty (30) days written notice to HI-POWER of intention to cancel. ▇▇▇▇ understands and agrees that enforcement of all insurance coverage pursuant to this Article is the responsibility of ACRO, including coverage for all applicable subcontractors, and suppliers. 13.4 Subrogation. Subrogation against HI-POWER under ACRO’s insurance coverage pursuant to this Article shall be, and is hereby, waived. Evidence of such waiver satisfactory in form and substance to HI-POWER shall be exhibited in such certificates furnished hereunder.

Upon such termination by ACRO, HI-POWER shall pay to ACRO such amounts as ACRO would have been entitled to receive in the event of a termination for convenience by HI- POWER pursuant to Section 14.5. Notwithstanding anything to the contrary, ACRO’s sole and exclusive remedy for any breach of, or default under, this Agreement by HI-POWER shall be money damages, and ACRO shall have no right to terminate this Agreement (or to suspend performance of ACRO’s obligations hereunder or any portion thereof) for any such breach or default, except in the case of an uncured HI-POWER Event of Default. 14.4 HI-POWER Remedies Upon ACRO Event of Default. (a) Suspension, Take Over, and Termination. Upon the occurrence and during the continuation of an ACRO Event of Default, in addition to any or all other remedies available under this Agreement or at law or at equity, all of which shall be cumulative, HI-POWER has the right to suspend its or ACRO’s performance, to take over some or all of the Work pursuant to Section 14.4(b), or to terminate this Agreement upon ten (10) Business Days' notice to ACRO. If any termination for cause by HI-POWER pursuant to this Section 14.4 is ultimately determined to have been wrongful, then such termination shall be deemed a termination for convenience pursuant to Section 14.5 and ACRO's sole remedy shall be the receipt of the amounts set forth in Section 14.5(b). (b) ACRO's Obligations Following HI-POWER Take Over. If HI-POWER elects to perform some or all of the Work itself in accordance with Section 14.4(a), ACRO shall cooperate with HI-POWER, and allow HI-POWER to use all Work Product, including information, drawings, specifications documents, patents, and licenses related to the Work and all equipment and materials related to the Work, whether located on the Site or elsewhere, for the construction, installation, operation, maintenance, and commissioning, refurbishment, replacement, modification of, or addition to the Work or for any other purpose directly related to the requirements of the Line, and, if requested, instruct its Subcontractors to take direction from HI-POWER. HI-POWER may, in its sole discretion, perform the Work through Final Acceptance or perform some of the Work and then return care and custody of the appropriate portions of the Work to ACRO. In so doing, HI-POWER may employ any other Person, firm, or corporation to perform the Work by whatever method HI-POWER may deem expedient and may undertake such expenditures as in HI-POWER’s reasonable judgment will best accomplish the timely completion of the Work (including, where necessary, the entry into contracts without prior solicitation of proposals). If HI-POWER returns care and custody of the Work to ACRO, ACRO shall continue to be bound by its obligations hereunder and shall complete all such Work as required under this Agreement. HI-POWER’s exercise of its takeover rights under this Section 14.4 shall not relieve ACRO of any of its obligations hereunder (including ACRO’s Warranty obligations for Work performed by it and other ACRO Responsible Parties supplied by it and other ACRO Responsible Parties) and any other amounts due and payable by ACRO to HI-POWER hereunder (including payment of any Delayed Liquidated Damages incurred prior to HI-POWER’s exercise of its takeover rights under this Section 14.4(b)). In addition to the foregoing, if the Completion Cost exceeds the unpaid portion of the Contract Price for such scope of Work at the time HI-POWER takes over such scope of Work, ACRO shall pay HI-POWER the amount of such excess within ten (10) Business Days following receipt of HI-POWER’s demand for such payment. If the unpaid balance of the Price at the time of completion of the Work exceeds the Completion Costs paid by HI-POWER and not expressly waived, and any other amounts due by ACRO to HI-POWER under this Agreement, such excess shall be paid to ACRO but only for Work performed by ACRO in accordance with this Agreement. Notwithstanding anything to the contrary herein, (i) HI-POWER shall use commercially reasonable efforts to mitigate the costs and expenses it incurs when exercising its rights under this Section 14.4(b) and shall ensure that its other contractors perform their work in a manner so as not to interfere with ACRO’s performance of the Work; and (ii) ACRO shall have no Warranty

30 obligations associated with the work performed by HI-POWER or HI-POWER's other contractors or suppliers or any other responsibility for, or liability in connection with, the actions or omissions of HI-POWER’s other contractors or suppliers. (c) ACRO's Obligations Following HI-POWER's Termination for Cause. If HI-POWER terminates this Agreement pursuant to Section 14.4(a), upon HI-POWER's request, ACRO shall withdraw from the Site, shall assign to HI-POWER its subcontracts, purchase orders and permits as HI-POWER may request, and shall deliver and make available to HI-POWER all ACRO Intellectual Property (whether or not such information, drawings, specifications documents, patents, and licenses are complete) related to the Work reasonably necessary to permit HI- POWER to complete or cause the completion of the Work, and in connection therewith ACRO authorizes HI-POWER and its agents to use such information in completing the Work. ACRO shall act as agent of HI-POWER if requested by HI-POWER to enforce the assigned rights under contracts assigned to HI-POWER pursuant to this Section 14.4(c). HI-POWER shall have the right to take possession of all ACRO’s material, apparatuses and tools located at the Site for the purpose of completing the Work, with such material, apparatus and tools to be returned to ACRO upon the completion of the Work, and ACRO shall remove such materials, equipment, tools, and instruments used by and any debris or waste materials generated by ACRO in the performance of the Work as HI-POWER may direct. HI-POWER shall use reasonable efforts to mitigate the cost for completion of the Work, HI-POWER may employ any other Person, firm, or corporation to finish the Work by whatever method HI-POWER may deem reasonable and may undertake such reasonable expenditures as in HI-POWER’s reasonable judgment will best accomplish the timely completion of the Work (including, where necessary, the entry into contracts without prior solicitation of proposals). ACRO shall not be entitled to receive any further payments under this Agreement except for payments for Work performed in accordance with this Agreement prior to such termination. Termination of this Agreement by HI-POWER pursuant to Section 14.4(a) shall not relieve ACRO of any of its obligations hereunder (including ACRO’s Warranty obligations for Work performed by it and other ACRO Responsible Parties) and any other amounts due and payable by ACRO to HI-POWER hereunder (including payment of any Delayed Liquidated Damages incurred prior to HI-POWER's termination of this Agreement pursuant to Section 14.4(a)). In addition to the foregoing, if the Completion Costs to HI-POWER under this Section 14.4(c) exceeds the unpaid portion of the Price at the time of termination of this Agreement, ACRO shall pay HI-POWER the amount of such excess within ten (10) Business Days following receipt of HI-POWER’s demand for such payment. If the unpaid balance of the Price at the time of completion of the Work exceeds the Completion Costs incurred by HI-POWER and not expressly waived, and any other amounts due and payable by ACRO to HI-POWER under this Agreement, such excess shall be paid to ACRO but only for Work performed by ACRO in accordance with this Agreement. 14.5 Termination for Convenience by HI-POWER. (a) Termination. HI-POWER may terminate this Agreement or any Purchase Order for convenience in whole or in part, and such termination shall be effective upon the later of (x) the date of termination identified in such notice or (y) ten (10) Business Days after the date of such notice. Upon receipt of any such notice, ACRO shall, unless the notice directs otherwise: (i) immediately discontinue the Work on the date and to the extent specified in such notice; (ii) place no further orders or subcontracts for equipment or services except as may be necessary for completion of such portion of the Work as is not discontinued; (iii) promptly make every reasonable effort to procure cancellations upon terms reasonably satisfactory to HI-POWER of all orders, subcontracts, and rental agreements to the extent they relate to the performance of the Work that is discontinued on terms that mitigate the cost thereof; (iv) for the Work discontinued, deliver to HI-POWER all related ACRO Intellectual Property prepared as of the date of the termination and all related materials, parts, and equipment for which payment has been received from HI-POWER and otherwise provide such reasonable assistance, coordination and information as may be requested by HI-POWER to ensure an orderly transition of the discontinued Work to HI-POWER; (v) assign to HI-POWER any warranties of Subcontractors performing any portion of the Work; and

31 (vi) thereafter execute only that portion of the Work that has not been discontinued or only such discontinued Work as may be necessary to preserve and protect Work already in progress and to protect equipment at the Site or in transit thereto. (b) ACRO's Sole Remedies. ACRO waives any claims for damages, including loss of anticipated profits for uncompleted Work due to a termination for convenience by HI-POWER pursuant to this Section 14.5 and shall accept as its sole and exclusive remedy a sum equal to: (i) the value of Work performed and materials furnished to date; plus (ii) ACRO’s actual, reasonable, and demonstrable Demobilization costs plus a markup of 10% for overhead and profit, as demonstrated by documentation reasonably requested by HI-POWER; less (iii) the aggregate of amounts paid to ACRO for the Work prior to such termination; less (iv) the amount of any recoverable deposits paid to suppliers which are in fact recovered, net of any costs (including legal fees and expenses) to recover; less (v) any unpaid amounts due from ACRO to HI-POWER under this Agreement. As a condition precedent to ACRO's payment under this Section 14.5(b), ACRO shall: (A) submit to HI-POWER all documentation required by Section 3.4; (B) submit to HI-POWER an invoice for the amount provided hereunder; and (C) deliver all such documents and take all such steps, including the assignment of ACRO’s and Subcontractor’s contractual rights, as HI- POWER may require for the purpose of fully vesting in HI-POWER all rights, title and interests of ACRO in and to all subcontracts, purchase orders, warranties, guarantees, and other agreements pertaining to the Work completed. (c) Assignment of Warranties. Solely in the event of termination by HI-POWER pursuant to this Section 14.5, and notwithstanding anything to the contrary in this Agreement, including Article 11, ACRO’s sole responsibility with respect to the warranty obligations set forth in Article 11 shall be to assign the warranties, if any, of its Subcontractors pursuant to Section 14.5(a)(v); provided that the foregoing shall not limit ACRO’s obligations to assign subcontracts to HI-POWER as contemplated in Section 12.5. ARTICLE 15. ASSIGNMENT; FINANCING COOPERATION 15.1 General Restriction on Assignment. Subject to Section 15.2, neither Party shall assign, or in any other manner transfer, any of its rights or obligations under this Agreement without the prior written consent of the other Party. No such purported assignment or transfer without such consent, whether voluntary or involuntary, by operation of Applicable Laws, under legal process or proceedings, by receivership, in bankruptcy, or otherwise, shall be valid or effective. Notwithstanding the foregoing, nothing in this Section 15.1 shall prohibit ACRO from subcontracting all or any portion of the Work hereunder in accordance with the provisions of this Agreement (provided that no such subcontracting shall relieve ACRO of any obligation hereunder). For the avoidance of doubt, a change in Control of a Party shall constitute an assignment prohibited by this Section 15.1. 15.2 Permitted Assignments. Notwithstanding Section 15.1, HI-POWER (or its assignee pursuant to this Section 15.2) may, without ACRO's consent, but with written notice to ACRO: (i) assign, in whole or in part, this Agreement to (A) any Interested Party, (B) any Affiliate of HI-POWER, or (C) any special purpose company formed by HI-POWER or a Purchaser, or their respective Affiliates for the purpose of developing, financing, and owning the Project or any portion thereof, or administering construction of the Project (or any portion thereof) under this Agreement; or (ii) collaterally assign this Agreement as security to any Interested Party; provided, however, that any assignment of this Agreement by HI-POWER pursuant to the foregoing subclause (i), but not subclause (ii), shall release HI-POWER from its further liabilities under this Agreement. 15.3 Project Lender and Purchaser Accommodations. ACRO shall provide reasonable cooperation and assurances as HI-POWER shall reasonably request in connection with any debt or equity (including tax equity) financing or refinancing of the development, construction, and/or operation of the Project, any sale of the Project or of all or substantially all of HI-POWER’s assets, or any permitted assignment of this Agreement. Such cooperation shall include the following: (a) with respect to a Project Lender, executing and delivering a consent and acknowledgment substantially in form and substance reasonably satisfactory to Project Lender and HI-POWER, consenting to the pledge or collateral assignment of this Agreement and a first security interest in the Project (collectively, the “Project Lender’s Security Interest”);

32 (b) providing to HI-POWER and Project Lender and/or any Purchaser a favorable written opinion of counsel to ACRO (which may be provided by internal legal counsel to ACRO) covering such matters relating to ACRO and this Agreement as Project Lender and/or any Purchaser shall reasonably request, including: (i) the due execution of, and corporate power and capacity of ACRO to enter into, this Agreement, and (ii) the enforceability of this Agreement and the consent and acknowledgment provided in accordance with Section 15.3(a) above against ACRO; (c) if any changes to the forms of consent and acknowledgement, legal opinion, referred to above in this Section 15.3 are requested by HI-POWER, Project Lender or any Purchaser, ACRO shall act reasonably in negotiating such changes; and (d) participating in meetings with Interested Parties and responding to reasonable requests for information regarding ACRO'S qualifications, creditworthiness, and the status of the Work. For clarity, ACRO will only share its financial information with HI-POWER, Project Lender or other entities that have executed ACRO’s standard nondisclosure agreement. 15.4 Subordination of Liens. ACRO agrees to comply, and use commercially reasonable efforts to cause Subcontractors to comply, with reasonable requests of HI-POWER in connection with the subordination of any and all Liens and other rights and claims to Liens that may be brought by ACRO or any Subcontractor against any or all of the Work, the Site, or the Project, including the execution and delivery of subordination agreements, affidavits or other documents that may be required to demonstrate that HI-POWER's property and premises are free from Liens arising out of the furnishing of Work under this Agreement. ARTICLE 16. REPRESENTATIONS AND WARRANTIES 16.1 Knowledge and Experience. ACRO has (either directly or through its Subcontractors) all the required authority, ability, skill, experience, and capacity necessary to perform the Work and diligently do so in a timely and professional manner, utilizing sound project management procedures, construction procedures, and supervisory procedures, all in accordance with this Agreement, Applicable Laws, Governmental Approvals and Prudent Industry Standards.

Furthermore, neither Party shall disclose any Confidential Information to any Third Party other than (A) to its and its Affiliates officers, employees, Interested Parties, counsel, accountants or advisors (collectively, the "Representatives"); provided, however, that, such Representatives have a need to know such Confidential Information for the purposes permitted by this Agreement and have agreed to keep such terms confidential or are otherwise bound by confidentiality obligations at least as restrictive as those contained herein; or (B) in order to comply with any Applicable Laws or any exchange, control area or independent system operator rule, tariff or agreement, or in connection with any judicial or regulatory proceeding or request by a Governmental Authority; provided, however, that each Party shall immediately notify the other in writing of such proceeding or request and will seek to prevent or limit any such disclosure. For the avoidance of doubt, all of ACRO's confidentiality obligations under that certain Mutual Confidentiality and Non-Disclosure Agreement dated June 6, 2022 between Eos Energy Storage LLC (an Affiliate of HI-POWER) and ACRO remain in full force and effect during the Term and such confidentiality obligations shall survive for a period of five (5) years from the date of termination or expiration of this Agreement, except with respect to trade secrets which in which case such confidentiality obligations shall survive indefinitely. 17.4 Public Announcements. ACRO shall not make any public announcements regarding this Agreement or the transactions contemplated hereby without HI-POWER's prior written approval. ARTICLE 18. MISCELLANEOUS 18.1 Entire Agreement. This Agreement, together with all Exhibits and Appendices hereto, embodies the entire agreement and understanding of the Parties with respect to the subject matter hereof and supersedes all prior or contemporaneous agreements and understandings of the Parties, verbal or written, relating to the subject matter hereof. 18.2 Waiver. Any waiver of the provisions of this Agreement must be in writing signed or acknowledged by the waiving party and shall not be implied by any usage of trade, course of dealing or course of performance. No exercise of any right or remedy by HI-POWER or ACRO shall constitute a waiver of any other right or remedy contained herein or provided by Applicable Laws. Any delay or failure of a Party to exercise, or any partial exercise of, its rights and remedies under this Agreement shall not operate to limit or otherwise affect such rights or remedies nor shall it be construed as a bar to or waiver of any such right or remedy on any future occasion. Any waiver of performance hereunder shall be limited to the specific performance waived and shall not, unless otherwise expressly stated in writing, constitute a continuous waiver or a waiver of future performance or otherwise affect any other requirements or obligations. 18.3 Disputes. (a) Management Negotiations. Following notice from either Party setting forth a dispute arising from or relating to this Agreement (other than disputes related to ACRO Tests, which shall be resolved in accordance with Section 18.3(d)), which notice shall reference this Article 18 ("Senior Management Notice"), the Parties shall use good faith efforts to settle disputes through negotiation between authorized members of each Party's senior management with the power and authority to resolve any such dispute. A meeting at a mutually agreed upon hour and location, whether by phone or in person, between each Party's senior management ("Senior Management Meeting") shall be held within fifteen (15) Business Days following a Party's receipt of any Senior Management Notice. If the dispute is not resolved within thirty (30) days after the delivery of any Senior Management Notice, either Party may, by written notice to the other Party, refer the issues set forth in such Senior Management Notice to meditation pursuant to Section 18.3(b) ("Mediation Notice").

35 (b) Compulsory Mediation and Binding Arbitration. (i) Within 10 Business Days after a Party's receipt of a Mediation Notice, the Parties shall cooperate in selecting a qualified neutral mediator from among a panel of neutral persons proposed by the American Arbitration Association, or any other mutually acceptable organization, and in scheduling the mediation to commence on a date that is no later than thirty (30) days after a Party's receipt of the Mediation Notice. The place of mediation shall be Pittsburgh, Pennsylvania. The Parties agree to participate in the mediation in good faith and to share the costs of the mediation, including the mediator's fee, equally, but such shared costs shall not include each Party's own attorneys' fees and costs, which shall be borne solely by such Party. If the Parties are unable to resolve their dispute through mediation within sixty (60) days following a Party's receipt of the Mediation Notice, then either Party may refer the issues set forth in such Mediation Notice to binding arbitration pursuant to Section 18.3(b)(ii) ("Arbitration Notice"). Notwithstanding anything to the contrary in this Section 18.3(b), in the event ACRO's lien rights under Applicable Law would expire prior to the end of the foregoing sixty-day period, then ACRO shall be entitled to take such actions as are necessary to timely preserve its lien rights under Applicable Law during such sixty- day period. (ii) HI-POWER and ACRO agree that any other matters in question between HI- POWER and ACRO arising out of or relating to this Agreement, or the breach thereof or hereof, that is not resolved through the mediation process set forth in Section 18.3(b)(i), shall be decided by arbitration in accordance with the American Arbitration Association rules then in effect (except as modified herein). In the event that the dispute involves less than $500,000.00 (exclusive of attorneys' fees, costs and interest), HI-POWER and ACRO agree: (1) that the only discovery permitted in connection with the arbitration shall be a mutual exchange of relevant project documents, which shall occur at least fifteen (15) days before the start of the arbitration hearings; and (2) that the arbitration hearings shall proceed on an expedited basis and shall not last more than three (3) days, with the hearing time being split equally between the Parties. The right to arbitration shall be enforceable under Applicable Law, including the U. S. Federal Arbitration Act. The award of the arbitrator(s) shall be final and binding without the right of appeal to the courts. Judgment may be entered upon it in accordance with Applicable Law by any court having jurisdiction thereof. The Parties hereby (i) consent to the personal jurisdiction of the federal courts of the United States or the courts of the Commonwealth of Pennsylvania sitting in the City/County of Pittsburgh, Alleghany County, Pennsylvania in connection with any controversy related to arbitration; (ii) waive any argument that venue in any such forum is not convenient, (iii) agree that any litigation initiated by ACRO or HI-POWER (or their affiliates or designees) in connection with arbitration or otherwise related to this Agreement (subject to the requirement to arbitrate) may be venued in either the federal courts of the United States or the courts of the Commonwealth of Pennsylvania sitting in the City/County of Pittsburgh, Alleghany County, Pennsylvania; and (iv) agree that a final judgment in any such suit, action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. EACH OF THE PARTIES HERETO KNOWINGLY, VOLUNTARILY, INTENTIONALLY, AND IRREVOCABLY WAIVES ANY RIGHT IT MAY NOT OR HEREAFTER HAVE TO A TRIAL BY JURY IN ANY LITIGATION BASED HEREIN, OR ARISING OUT OF, UNDER OR IN RESPECT OF THIS AGREEMENT, OR ANY COURSE OF CONDUCT, COURSE OF DEALING, STATEMENTS (WHETHER ORAL OR WRITTEN) OR ACTIONS OF THE PARTIES HERETO. The foregoing references to litigation are not to be construed as a waiver of the obligation to arbitrate. (c) Confidentiality. All communication, offers and statements, whether oral or written, and documents and other writings exchanged between the Parties in connection with the management negotiations pursuant to Section 18.3(a) and any mediation or arbitration pursuant to Section 18.3(b) shall be confidential and shall not be discoverable, admissible in evidence or used or referred to in any subsequent binding adjudicatory process between the Parties; provided, however, that evidence that is otherwise admissible or discoverable shall not be rendered inadmissible or non-discoverable as a result of its use in such negotiations. (d) Technical Disputes. Any disputes related to (i) the performance of ACRO Tests, or (ii) the validity of a Warranty claim submitted by HI-POWER under this Agreement shall be resolved on an accelerated basis in accordance with this Section 18.3(d). Following written notice from either Party setting forth a dispute relating to a ACRO Test or following ▇▇▇▇’s rejection of a Warranty claim made by HI-POWER, as the case may be, the Parties shall submit such dispute to an independent engineer for resolution within five (5) days of such written notice. Each Party shall provide the independent engineer with a summary of the dispute and a proposed resolution, and each Party may provide relevant information supporting its position and proposed resolution but agrees to appropriately

36 calibrate the quantity of such information in recognition of the expedited nature of these proceedings. The independent engineer shall render a decision resolving the matter within ten (10) days of receipt of both Parties' proposal. The decision of the independent engineer shall be final and binding upon the Parties, but shall be subject to appeal or review, whether through litigation, arbitration, or otherwise; provided that the Parties shall follow the decision of the independent engineer until such appeal is finally decided. The losing Party shall pay all costs and expenses of the independent engineer and the independent engineer shall not have the authority to award costs or attorneys' fees to either Party. (e) Work Notwithstanding Disputes. Unless otherwise agreed to in writing, ACRO shall diligently carry on the Work during the pendency of any dispute so long as all undisputed amounts due to ACRO hereunder have been paid. Upon resolution of such dispute, whether by agreement of the Parties or through a dispute proceeding, any amounts found to be owing by either Party will be promptly paid by the Party owing payment to the other Party, together with interest at the Interest Rate (or, if lower than the Interest Rate, the highest rate permitted by Applicable Laws) from the day following the date of the overpayment or underpayment, as applicable, until and including the date of repayment in full. 18.4 Governing Law and Forum Selection Clause. This Agreement and all matters arising hereunder or in connection herewith shall be governed by, and interpreted and construed in accordance with, the laws of the United States and the Commonwealth of Pennsylvania, excluding choice of law rules that would result in the application of the laws of another jurisdiction. Any claim or dispute arising out of or in connection with this Agreement must be brought in a federal or state court of competent jurisdiction within the State of Pennsylvania, United States of America, and each Party consents and agrees to submit to the sole and exclusive personal jurisdiction and venue of such courts. 18.5 Reserved. 18.6 Construction. This Agreement is to be construed so as to effectuate the normal and reasonable expectations of a sophisticated buyer and seller of the equipment and services covered by this Agreement and shall not be construed either for or against either Party.

ACRO and its Subcontractors shall be independent contractors to HI- POWER with respect to the Work, irrespective of whether such Subcontractors are approved by HI-POWER, and neither ACRO nor its Subcontractors, nor the employees or agents of either, shall be deemed to be the employees, representatives, or agents of HI-POWER in connection with any matter relating to this Agreement. No provision of this Agreement shall be construed or represented as creating a partnership, trust, joint venture, fiduciary, or any similar relationship between the Parties. ▇▇▇▇ understands and agrees that, as an independent contractor its employees will receive no benefits of any type from HI-POWER. ACRO shall satisfy all responsibilities imposed by Governmental Authorities on employers, and all amounts paid in satisfying such responsibilities are included in the Price. 18.9 No Third-Party Beneficiaries. This Agreement is made and entered into for the sole protection and legal benefit of HI-POWER and ACRO, and their permitted successors and assigns, and, unless otherwise provided herein with respect to the Indemnified Parties, no other Person shall be a direct or indirect legal beneficiary of, or have any direct or indirect cause of action or claim in connection with, this Agreement. 18.10 Further Assurances. Each Party agrees to execute and deliver all further instruments and documents, and take all further action, as may be reasonably necessary to complete performance by the Parties hereunder and to effectuate the purposes and intent of this Agreement. Without limiting the foregoing, each Party, at the reasonable request of the other, will, without further consideration, promptly execute and deliver or cause to be executed and delivered to the other such assistance, or assignments, consents, or other instruments in addition to those required by this Agreement, in form and substance satisfactory to the other, as the other may reasonably deem necessary or desirable to implement any provision of this Agreement.

38753581.v20 APPENDIX 1 GOVERNMENT FLOW DOWNS This Agreement is financed through the Department of Energy’s Loan Guarantee Program. The following clauses are required to be included in this Agreement either by the terms of the DOE loan agreement or by statutes and regulations applicable to Federal financial assistance agreements. 1. ▇▇▇▇▇ ▇▇▇▇▇ and Related Acts (DBRA) All laborers and mechanics employed by contractors and subcontractors in the performance of construction work under this agreement must be paid wages at rates not less than those prevailing on projects of a character similar in the locality as determined by the Secretary of Labor in accordance with subchapter IV of chapter 31 of title 40, United States Code (the “▇▇▇▇▇-▇▇▇▇▇ Act”). ACRO shall comply with the ▇▇▇▇▇-▇▇▇▇▇ Act and all applicable ▇▇▇▇▇-▇▇▇▇▇ Act regulations, including all requirements set forth in 29 CFR Part 5 and the applicable wage determination schedule(s) in performing this agreement. a. Minimum wages. (i) All laborers and mechanics employed or working upon the site of the work (or under the United States Housing Act of 1937 or under the Housing Act of 1949 in the construction or development of the project), will be paid unconditionally and not less often than once a week, and without subsequent deduction or rebate on any account (except such payroll deductions as are permitted by regulations issued by the Secretary of Labor under the ▇▇▇▇▇▇▇▇ Act (29 CFR part 3)), the full amount of wages and bona fide fringe benefits (or cash equivalents thereof) due at time of payment computed at rates not less than those contained in the wage determination of the Secretary of Labor which is attached hereto and made a part hereof, regardless of any contractual relationship which may be alleged to exist between ACRO and such laborers and mechanics. Contributions made or costs reasonably anticipated for bona fide fringe benefits under section 1(b)(2) of the ▇▇▇▇▇– ▇▇▇▇▇ Act on behalf of laborers or mechanics are considered wages paid to such laborers or mechanics, subject to the provisions of paragraph (a)(iv) of this Section; also, regular contributions made or costs incurred for more than a weekly period (but not less often than quarterly) under plans, funds, or programs which cover the particular weekly period, are deemed to be constructively made or incurred during such weekly period. Such laborers and mechanics shall be paid the appropriate wage rate and fringe benefits on the wage determination for the classification of work actually performed, without regard to skill, except as provided in paragraph (d) of this Section. Laborers or mechanics performing work in more than one classification may be compensated at the rate specified for each classification for the time actually worked therein: Provided, That the employer's payroll records accurately set forth the time spent in each classification in which work is performed. The wage determination (including any additional classification and wage rates conformed under paragraph (a)(ii) of this Section) and the ▇▇▇▇▇–▇▇▇▇▇ poster (WH–1321) shall be posted at all times by ACRO and its contractors and subcontractors at the site of the work in a prominent and accessible place where it can be easily seen by the workers. (ii) (A) Any class of laborers or mechanics, including helpers, which is not listed in the wage determination and which is to be employed under the contract shall be classified in conformance with the wage determination. An additional classification and wage rate and fringe benefits therefore will be approved only when the following criteria have been met: (1) The work to be performed by the classification requested is not performed by a classification in the wage determination; and (2) The classification is utilized in the area by the construction industry; and

2 (3) The proposed wage rate, including any bona fide fringe benefits, bears a reasonable relationship to the wage rates contained in the wage determination. (B) If ACRO and the laborers and mechanics to be employed in the classification (if known), or their representatives, and HI-POWER (in consultation with the government) agree on the classification and wage rate (including the amount designated for fringe benefits where appropriate), a report of the action taken shall be sent by the by the government through HI-POWER to the Administrator of the Wage and Hour Division, U.S. Department of Labor, Washington, DC 20210. The Administrator, or an authorized representative, will approve, modify, or disapprove every additional classification action within 30 days of receipt and so advise the government or will notify the government within the 30–day period that additional time is necessary. (C) In the event ACRO, the laborers or mechanics to be employed in the classification or their representatives, and HI-POWER (in consultation with the government) do not agree on the proposed classification and wage rate (including the amount designated for fringe benefits, where appropriate), the government (through HI- POWER) shall refer the questions, including the views of all interested parties and the recommendation of the government, to the Administrator for determination. The Administrator, or an authorized representative, will issue a determination within 30 days of receipt and so advise the government or will notify the government within the 30–day period that additional time is necessary. (D) The wage rate (including fringe benefits where appropriate) determined pursuant to paragraphs (a)(ii)(B) or (C) of this Section, shall be paid to all workers performing work in the classification under this contract from the first day on which work is performed in the classification. (iii) Whenever the minimum wage rate prescribed in the contract for a class of laborers or mechanics includes a fringe benefit which is not expressed as an hourly rate, ACRO shall either pay the benefit as stated in the wage determination or shall pay another bona fide fringe benefit or an hourly cash equivalent thereof. (iv) If ACRO does not make payments to a trustee or other third person, ACRO may consider as part of the wages of any laborer or mechanic the amount of any costs reasonably anticipated in providing bona fide fringe benefits under a plan or program, Provided, That the Secretary of Labor has found, upon the written request of ACRO, that the applicable standards of the ▇▇▇▇▇–▇▇▇▇▇ Act have been met. The Secretary of Labor may require ACRO to set aside in a separate account assets for the meeting of obligations under the plan or program. b. Withholding. HI-POWER (or the Department of Energy) shall upon its own action or upon written request of an authorized representative of the Department of Labor withhold or cause to be withheld from ACRO under this agreement or any other Federal contract with the same contractor, or any other federally-assisted contract subject to ▇▇▇▇▇–▇▇▇▇▇ prevailing wage requirements, which is held by the same contractor, so much of the accrued payments or advances as may be considered necessary to pay laborers and mechanics, including apprentices, trainees, and helpers, employed by ACRO or any contractor or subcontractor the full amount of wages required by the contract. In the event of failure to pay any laborer or mechanic, including any apprentice, trainee, or helper, employed or working on the site of the work (or under the United States Housing Act of 1937 or under the Housing Act of 1949 in the construction or development of the project), all or part of the wages required by the contract, the (Agency) may, after written notice to ACRO, sponsor, applicant, or owner, take such action as may be necessary to cause the suspension of any further payment, advance, or guarantee of funds until such violations have ceased. c. Payrolls and basic records.

3 (i) Payrolls and basic records relating thereto shall be maintained by ACRO during the course of the work and preserved for a period of three years thereafter for all laborers and mechanics working at the site of the work (or under the United States Housing Act of 1937, or under the Housing Act of 1949, in the construction or development of the project). Such records shall contain the name, address, and social security number of each such worker, his or her correct classification, hourly rates of wages paid (including rates of contributions or costs anticipated for bona fide fringe benefits or cash equivalents thereof of the types described in section 1(b)(2)(B) of the ▇▇▇▇▇–▇▇▇▇▇ Act), daily and weekly number of hours worked, deductions made and actual wages paid. Whenever the Secretary of Labor has found under 29 CFR 5.5(a)(1)(iv) that the wages of any laborer or mechanic include the amount of any costs reasonably anticipated in providing benefits under a plan or program described in section 1(b)(2)(B) of the ▇▇▇▇▇–▇▇▇▇▇ Act, ACRO shall maintain records which show that the commitment to provide such benefits is enforceable, that the plan or program is financially responsible, and that the plan or program has been communicated in writing to the laborers or mechanics affected, and records which show the costs anticipated or the actual cost incurred in providing such benefits. Contractors employing apprentices or trainees under approved programs shall maintain written evidence of the registration of apprenticeship programs and certification of trainee programs, the registration of the apprentices and trainees, and the ratios and wage rates prescribed in the applicable programs. (ii) (A) ACRO shall submit weekly for each week in which any contract work is performed a copy of all payrolls to HI-POWER for transmission to the Department of Energy. The payrolls submitted shall set out accurately and completely all of the information required to be maintained under 29 CFR 5.5(a)(3)(i), except that full social security numbers and home addresses shall not be included on weekly transmittals. Instead the payrolls shall only need to include an individually identifying number for each employee (e.g., the last four digits of the employee's social security number). The required weekly payroll information may be submitted in any form desired. Optional Form WH–347 is available for this purpose from the Wage and Hour Division Web site at ▇▇▇▇://▇▇▇.▇▇▇.▇▇▇/▇▇▇/▇▇▇/▇▇▇▇▇/▇▇▇▇▇▇▇▇▇▇.▇▇▇ or its successor site. ▇▇▇▇ is responsible for the submission of copies of payrolls by all lower-tier contractors and subcontractors. Contractors and subcontractors shall maintain the full social security number and current address of each covered worker, and shall provide them upon request to HI-POWER for transmission to the Department of Energy or the Wage and Hour Division of the Department of Labor for purposes of an investigation or audit of compliance with prevailing wage requirements. It is not a violation of this section for HI- POWER to require a contractor or subcontractor to provide addresses and social security numbers to HI-POWER for its own records, without weekly submission to the sponsoring government agency (or the applicant, sponsor, or owner). (B) Each payroll submitted shall be accompanied by a "Statement of Compliance" signed by ACRO or contractor or subcontractor or his or her agent who pays or supervises the payment of the persons employed under the agreement and shall certify the following: (1) That the payroll for the payroll period contains the information required to be provided under § 5.5 (a)(3)(ii) of Regulations, 29 CFR part 5 (see paragraph (c)(ii) of this Section), the appropriate information is being maintained under § 5.5 (a)(3)(i) of Regulations, 29 CFR part 5 (see paragraph (c)(i) of this Section), and that such information is correct and complete; (2) That each laborer or mechanic (including each helper, apprentice, and trainee) employed on the contract during the payroll period has been paid the full weekly wages earned, without rebate, either directly or indirectly, and that no deductions have been made either directly or

4 indirectly from the full wages earned, other than permissible deductions as set forth in Regulations, 29 CFR part 3; (3) That each laborer or mechanic has been paid not less than the applicable wage rates and fringe benefits or cash equivalents for the classification of work performed, as specified in the applicable wage determination incorporated into the contract. (C) The weekly submission of a properly executed certification set forth on the reverse side of Optional Form WH–347 shall satisfy the requirement for submission of the “Statement of Compliance” required by this section. (D) The falsification of any of the above certifications may subject ACRO, contractor or subcontractor to civil or criminal prosecution under section 1001 of title 18 and section 231 of title 31 of the United States Code. (iii) ACRO, contractor or subcontractor shall make the records required under paragraph (c)(i) of this Section available for inspection, copying, or transcription by authorized representatives of HI-POWER, the Department of Energy, or the Department of Labor, and shall permit such representatives to interview employees during working hours on the job. If ACRO, contractor or subcontractor fails to submit the required records or to make them available, the Federal agency may, after written notice to HI-POWER, take such action as may be necessary to cause the suspension of any further payment, advance, or guarantee of funds. Furthermore, failure to submit the required records upon request or to make such records available may be grounds for debarment action pursuant to 29 CFR 5.12. d. Apprentices and trainees— (i) Apprentices. Apprentices will be permitted to work at less than the predetermined rate for the work they performed when they are employed pursuant to and individually registered in a bona fide apprenticeship program registered with the U.S. Department of Labor, Employment and Training Administration, Office of Apprenticeship Training, Employer and Labor Services, or with a State Apprenticeship Agency recognized by the Office, or if a person is employed in his or her first 90 days of probationary employment as an apprentice in such an apprenticeship program, who is not individually registered in the program, but who has been certified by the Office of Apprenticeship Training, Employer and Labor Services or a State Apprenticeship Agency (where appropriate) to be eligible for probationary employment as an apprentice. The allowable ratio of apprentices to journeymen on the job site in any craft classification shall not be greater than the ratio permitted to the contractor as to the entire work force under the registered program. Any worker listed on a payroll at an apprentice wage rate, who is not registered or otherwise employed as stated above, shall be paid not less than the applicable wage rate on the wage determination for the classification of work actually performed. In addition, any apprentice performing work on the job site in excess of the ratio permitted under the registered program shall be paid not less than the applicable wage rate on the wage determination for the work actually performed. Where a contractor is performing construction on a project in a locality other than that in which its program is registered, the ratios and wage rates (expressed in percentages of the journeyman's hourly rate) specified in the contractor's or subcontractor's registered program shall be observed. Every apprentice must be paid at not less than the rate specified in the registered program for the apprentice's level of progress, expressed as a percentage of the journeymen hourly rate specified in the applicable wage determination. Apprentices shall be paid fringe benefits in accordance with the provisions of the apprenticeship program. If the apprenticeship program does not specify fringe benefits, apprentices must be paid the full amount of fringe benefits listed on the wage determination for the applicable classification. If the Administrator determines that a different practice prevails for the applicable apprentice classification, fringes shall be paid in accordance with that

5 determination. In the event the Office of Apprenticeship Training, Employer and Labor Services, or a State Apprenticeship Agency recognized by the Office, withdraws approval of an apprenticeship program, the contractor will no longer be permitted to utilize apprentices at less than the applicable predetermined rate for the work performed until an acceptable program is approved. (ii) Trainees. Except as provided in 29 CFR 5.16, trainees will not be permitted to work at less than the predetermined rate for the work performed unless they are employed pursuant to and individually registered in a program which has received prior approval, evidenced by formal certification by the U.S. Department of Labor, Employment and Training Administration. The ratio of trainees to journeymen on the job site shall not be greater than permitted under the plan approved by the Employment and Training Administration. Every trainee must be paid at not less than the rate specified in the approved program for the trainee's level of progress, expressed as a percentage of the journeyman hourly rate specified in the applicable wage determination. Trainees shall be paid fringe benefits in accordance with the provisions of the trainee program. If the trainee program does not mention fringe benefits, trainees shall be paid the full amount of fringe benefits listed on the wage determination unless the Administrator of the Wage and Hour Division determines that there is an apprenticeship program associated with the corresponding journeyman wage rate on the wage determination which provides for less than full fringe benefits for apprentices. Any employee listed on the payroll at a trainee rate who is not registered and participating in a training plan approved by the Employment and Training Administration shall be paid not less than the applicable wage rate on the wage determination for the classification of work actually performed. In addition, any trainee performing work on the job site in excess of the ratio permitted under the registered program shall be paid not less than the applicable wage rate on the wage determination for the work actually performed. In the event the Employment and Training Administration withdraws approval of a training program, the contractor will no longer be permitted to utilize trainees at less than the applicable predetermined rate for the work performed until an acceptable program is approved.
