7.3.1 ▇▇▇▇▇▇ Mechanical shall notify Owner when it believes the Plant has achieved Substantial Completion and, with or before such notice. ▇▇▇▇▇▇ Mechanical shall prepare and issue a Certificate of Substantial Completion that will set forth (i) the date of Substantial Completion of the Work, (ii) the remaining items of Work that have to be completed before Final Completion (omissions of an item from the list shall not be a waiver of the right to have such items of Work done or an admission that it was done), (iii) provisions (to the extent not already provided in the Contract) establishing Owner’s and ▇▇▇▇▇▇ Mechanical’s responsibility for the Plant’s security, maintenance, utilities and insurance pending final payment and (iv) an acknowledgment that warranties commence to run on the date of Substantial Completion, except as may otherwise be

noted in the Certificate of Substantial Completion. Within five (5) days of Owner’s receipt of ▇▇▇▇▇▇ Mechanical’s notice, Owner and ▇▇▇▇▇▇ Mechanical will jointly inspect the Plant Work to verify the Plant has achieved Substantial Completion with permanent equipment installed in operating condition and order required under the Contract, and verify the additional Work necessary to complete before Final Completion and to develop a mutually-agreeable Punch List. Owner shall give notice of objection to the claim of Substantial Completion within seven (7) days of the joint inspection date. Owner shall, within seven calendar days after the inspection deliver to ▇▇▇▇▇▇ Mechanical its proposed Punch List signed by Owner’s Representative. Such Punch List shall clearly designate which items, if any, need to be completed in order to reach Final Completion. ▇▇▇▇▇▇ Mechanical shall within six (6) calendar days of receipt of the Punch List ▇▇▇▇ the list to show ▇▇▇▇▇▇ Mechanical’s disagreement, if any, with any of the items listed by Owner, and return a copy of the list so marked and signed by ▇▇▇▇▇▇ Mechanical to Owner. In the event that Parties do not agree on the items that should be included on the Punch List within eight (8) calendar days thereafter, then either Party may submit the matter to disputes resolution under Section 17 below.

7.3.2 Upon achieving Substantial Completion, Hams Mechanical shall proceed to complete the Work and Delta-T with assistance from ▇▇▇▇▇▇ Mechanical and Owner will continue the Performance Test protocol described at Exhibit C in effort to attain 100% of the performance guarantees as prescribed by Exhibit D for the periods required by Exhibit D. Upon achieving Substantial Completion, Owner shall release to ▇▇▇▇▇▇ Mechanical 90% of the Retainage, and the remaining 10% of the Retainage shall be retained until Final Completion or, if earlier, until the Plant achieves 100% of the performance guarantees as prescribed by Exhibit D for the periods required by Exhibit D. If earlier than Final Completion the Plant achieves 100% of the performance guarantees, the then remaining Retainage shall be released, less an amount equal to 150% of the reasonable value of all remaining or incomplete items of Work as noted in the Certificate of Substantial Completion or as previously documented in writing.

7.3.3 At Substantial Completion, care, custody and control of the Plant, shall pass to Owner. Subsequent to Substantial Completion, Owner will permit ▇▇▇▇▇▇ Mechanical access to the Plant, subject only to restrictions as necessary for security and safety, so that ▇▇▇▇▇▇ Mechanical may conduct Corrective Action and additional Performance

Tests as provided in this Article 7. After Substantial Completion, Owner shall be solely-responsible for providing property insurance coverage of the Plant, provided, however, that (i) a Certificate of Substantial Completion has been issued for the portion of Work addressing the items set forth in Section 7.3.1 above, (ii) ▇▇▇▇▇▇ Mechanical and Owner have obtained the consent of their sureties and insurers, and to the extent applicable, the appropriate government authorities having jurisdiction over the Plant, and (iii) Owner’s use or occupancy will not significantly interfere with ▇▇▇▇▇▇ Mechanical’s completion of the remaining Work.

7.4 Training of Owner’s Personnel: ▇▇▇▇▇▇ Mechanical shall provide the training described in Exhibit A. Except as provided otherwise in Exhibit A, Owner shall provide appropriate personnel, and ▇▇▇▇▇▇ Mechanical shall provide such training, at times mutually agreed by them.

7.5 Failure to Reach Final Completion for Reasons Beyond ▇▇▇▇▇▇ Mechanical’s Control: If for any reason Owner fails to permit ▇▇▇▇▇▇ Mechanical access to the Plant after the date of Mechanical Completion in order to permit ▇▇▇▇▇▇ Mechanical to do all things necessary to achieve Final Completion, and such failure to permit access continues for an aggregate of thirty (30) days, then Final Completion shall be deemed to occur on the thirtieth day (in the aggregate) that such access is denied.

8. Payment

8.1 Contract Sum: Owner will pay ▇▇▇▇▇▇ Mechanical for the full and satisfactory completion of the Work the Contract Sum of $86,786,045.00, or such other sum as may be determined in accordance with Section 6 or Section 5. The Contract Sum does not include any sales or other tax. If ▇▇▇▇▇▇ Mechanical is; now or in the future, required to collect from Owner or pay any federal, state, local or other tax with respect to all or any part of the Work, then that amount shall be paid by Owner at ▇▇▇▇▇▇ Mechanical’s request, in addition to the Contract sum.

8.2 Payment Terms; Retainage: Owner shall make payment in accordance with this Section 8 and Exhibit ▇. ▇▇▇▇▇▇ Mechanical shall submit Applications for Payment in the form to be mutually agreed upon by the Parties and set forth at Exhibit B requesting payment for all Work performed as of the ▇▇▇▇ of the Application for Payment. The Application for Payment shall be accompanied by all supporting documentation required by the Contract in

the form of pay request, and shall include such other documentation as may be reasonably required by Owner’s lender(s). Five percent (5%) will be retained from all payments made hereunder and retained by Owner as “Retainage.” The 5% Retainage will be held on all payments made by the Owner to ▇▇▇▇▇▇ Mechanical until Final Completion. The Retainage is held in part by Owner as security for ▇▇▇▇▇▇ Mechanical’s performance of the Work. The entire Retainage amount is owed to ▇▇▇▇▇▇ Mechanical as the Final Payment once the Work has achieved Final Completion, less any liquidated damages.

The Application for Payment may request payment for equipment and materials not yet incorporated into the Plant, provided that (i) Owner is satisfied that the equipment and materials are suitably stored at either the Site (or another acceptable location if approved in writing in advance by Owner), (ii) the equipment and materials are protected by suitable insurance and (iii) upon payment, Owner will receive the equipment and materials free and clear of all liens and encumbrances. Applications for payment may also include the value of incremental progress payments owed by ▇▇▇▇▇▇ Mechanical to vendors of major items of equipment.

The Application for Payment shall constitute ▇▇▇▇▇▇ Mechanical’s representation that the Work has been performed consistent with the Contract, has progressed to the point indicated in the Application for Payment, and that title to all Work will pass to Owner free and clear of all claims, liens, encumbrances, and security interests upon the incorporation of the Work into the Plant, or upon ▇▇▇▇▇▇ Mechanical’s receipt of payment, whichever occurs earlier.

If required by Owner, the Application for Payment shall be verified as accurate and notarized and supported by such data substantiating ▇▇▇▇▇▇ Mechanical’s right to payment as Owner may reasonably require. If requested by Owner, ▇▇▇▇▇▇ Mechanical shall provide lien waivers for itself for the current Application for Payment and for Subcontractors, Sub-subcontractors, and Design Consultants for the previous Application for Payments before ▇▇▇▇▇▇ Mechanical has earned or has the right to receive any payment. All lien waivers shall be provided on a mutually agreed upon form. With the Final Application for Payment, ▇▇▇▇▇▇ Mechanical shall furnish final lien waivers to Owner for all Work furnished by ▇▇▇▇▇▇ Mechanical, Subcontractors, Sub-subcontractors, Design Consultants, and other persons furnishing labor or materials for the Work, as a precondition to Final Payment. This Section

shall not limit other obligations of ▇▇▇▇▇▇ Mechanical contained elsewhere to provide lien waivers.

Application for Payment shall not include requests for payment for portions of the Work for which ▇▇▇▇▇▇ Mechanical does not intend to pay a Design Consultant or Subcontractor within thirty (30) days, unless such Work has been performed by others whom ▇▇▇▇▇▇ Mechanical intends to pay within thirty (30) days.

Owner shall, through Owner’s Representative, sign the Certificate for Payment set forth on the Application for Payment for the full payment applied for, unless it believes that all or any part of such amount is not then due. If Owner believes all or part of the amount requested in the Application for Payment is not then due, Owner shall amend the Certificate for Payment contained therein by indicating the amount, if any, that it believes to be due, and shall sign the certificate as amended and deliver the certificate, together with written notice of Owner’s reasons for certifying less than the whole amount of applied for. If for any reason Owner’s Representative fails to deliver to ▇▇▇▇▇▇ Mechanical a signed Certificate for Payment within five (5) days prior to the date payment is due, then Owner shall be deemed to have waived any right it may have had to withhold all or any part of the payment applied for.

Provided ▇▇▇▇▇▇ Mechanical has properly submitted the Application for Payment with required documentation, and subject to Owner’s rights to withhold, Owner shall wire transfer, in immediately available funds, all amounts for which it has issued certificates, or failed to issue timely certificates, and if no time is indicated thereon, within thirty (30) days of the date of its receipt of the Application for Payment, to a bank account to be selected by ▇▇▇▇▇▇ Mechanical, at its sole discretion. Owner’s payment shall constitute a Certificate for Payment if the Certificate for Payment form is not executed by Owner. If Owner does not certify payment in the amount of the Application, and ▇▇▇▇▇▇ Mechanical and Owner cannot agree on a revised amount within five (5) days of the date of the Certificate for Payment for less than the full amount, then either Party may request a demand for arbitration in accordance with Section 17. In any case, when the reasons stated by Owner for withholding payment of any amount for which an application has been made are removed, in whole or in part, Owner shall immediately issue a Certificate for Payment for the amount withheld and make payment, via wire transfer as described in this Section 8.2, of the amount so certified on or before the date that the next payment is due, but in no case more than thirty (30) days after the date that such Certificate for Payment was due. ▇▇▇▇▇▇ Mechanical

shall pay Design Consultants and Subcontractors, in accordance with its contractual obligations to such parties, all the amounts ▇▇▇▇▇▇ Mechanical has received from Owner on account of such parties’ work. ▇▇▇▇▇▇ Mechanical will impose similar requirements on Design Consultants and Subcontractors to pay those parties with whom they have contracted.

8.3 Late Payment: Owner shall pay interest at the rate of Wall Street Prime on all sums past due, not to include those amounts contested in good faith by Owner, which interest shall commence thirty (30) days after payment is due.

8.4 Mechanic’s Lien Waivers and Indemnity: ▇▇▇▇▇▇ Mechanical shall pay promptly for all valid amounts due for all materials, labor and equipment used in or in connection with the performance of this Contract, including those of its subcontractor’s and vendors, when bills or claims become due, and shall indemnify and hold harmless Owner from and against all claims of its subcontractors and vendors for amounts due arising from ▇▇▇▇▇▇ Mechanical’s failure to make any such payments, provided that Owner gives ▇▇▇▇▇▇ Mechanical prompt notice of such claim and cooperates with ▇▇▇▇▇▇ Mechanical in defense of such claim.

8.5 Mechanic’s Liens: ▇▇▇▇▇▇ Mechanical shall keep the real property upon which the Plant is to be located free and clear of laborer’s, materialmen’s and mechanic’s liens arising out of the performance of the Work for which Owner has made payment. Owner shall promptly notify ▇▇▇▇▇▇ Mechanical in writing of any lien so arising of which it has notice or knowledge. ▇▇▇▇▇▇ Mechanical shall obtain and timely provide to Owner a partial release of lien with respect to any partial or progress payment made to relevant subcontractors and shall also obtain and timely provide a complete release of lien and general release with respect to any subcontract for which full and final payment is made. In each case, the release of lien may be for an amount less amounts that will be paid from the payment for which such release of lien is requested. ▇▇▇▇▇▇ Mechanical shall promptly pay each subcontractor upon receipt of payment from Owner of the amount invoiced that is due to such subcontractor.

8.6 Final Payment: ▇▇▇▇▇▇ Mechanical shall invoice Owner for the final amount due to it under this Contract upon reaching Final Completion. Payment of all of the Contract Sum remaining unpaid, arid any and all other amounts owing to ▇▇▇▇▇▇ Mechanical under the Contract, shall, unless provided otherwise in Exhibit B, be made within 30 days after Final Completion, subject to adjustment for any liquidated damages.

Owner acknowledges that ▇▇▇▇▇▇ Mechanical, particularly on large or fast-track projects, may not make final selection of some subcontractor or vendors until later in the project, and that ▇▇▇▇▇▇ Mechanical has the right to select subcontractors and vendors as long as the selection would not result in failure to satisfy the requirements of this Contract. The subcontracting, or sub-subcontracting, of any portion of the Work, as described in Exhibit A, shall not relieve ▇▇▇▇▇▇ Mechanical of responsibility for performance of the Work as provided therein. Notwithstanding the foregoing, ▇▇▇▇▇▇ Mechanical shall have the right to subcontract such portions of the Work as it shall determine to be necessary

to others which, in turn, shall have the right to subcontract such portions of the Work assigned to them, if any, as they shall deem necessary.

11.5 Cooperation. ▇▇▇▇▇▇ Mechanical agrees to cooperate at all times as reasonably requested by Owner and any lender or assignee of Owner and their respective agents and representatives in performance of this Contract. ▇▇▇▇▇▇ Mechanical shall sign any document reasonably required by Owner in order to satisfy all lenders or investors providing sources of funds for construction of the Plant. Owner may assign its interest to one or more lenders or financial institutions or investors, providing sources of funds for construction of the Plant, at any time, provided that the party taking the assignment can supply payment assurances acceptable to ▇▇▇▇▇▇ Mechanical.

12. Warranty

12.1 Equipment Warranties: For a period of one (1) year following Substantial Completion, ▇▇▇▇▇▇ Mechanical warrants to Owner that the construction, including all materials and equipment furnished as part of the construction, shall be new unless otherwise specified in Contract, of good quality, in conformance with the Contract, fit for their intended purpose, and free of defects in materials and workmanship. ▇▇▇▇▇▇ Mechanical’s warranty obligation excludes defects caused by abuse, alterations, or failure to maintain Work by persons other than ▇▇▇▇▇▇ Mechanical or anyone for whose acts ▇▇▇▇▇▇ Mechanical may be liable. ▇▇▇▇▇▇ Mechanical shall, for the protection of Owner, assign to Owner all warranties and guarantees supplied by all vendors and subcontractors from who it procured goods or services incorporated into the Project. In addition, ▇▇▇▇▇▇ Mechanical warrants to Owner that the Equipment will be free from mechanical defects, structural defects and defects in material and workmanship until the earlier of twelve (12) months from completion of the Performance Test, eighteen (18) months from Mechanical Completion, or twenty-four (24) months from delivery at the Plant site of that component. OWNER’S SOLE AND EXLCUSIVE REMEDY IN CASE OF BREACH OF THIS WARRANTY SHALL BE REPAIR OR REPLACEMENT AS PROVIDED IN THIS SECTION 12.1. If any defect covered by the above warranties is discovered within the warranty period, ▇▇▇▇▇▇ Mechanical shall, subject to the provisions set forth below, repair or replace the defective material or Equipment. The decision to repair or replace shall be made by Owner. If Owner and ▇▇▇▇▇▇ Mechanical do not agree on whether repair or replacement is the most appropriate remedy, and if the remedy recommended by ▇▇▇▇▇▇ Mechanical would not impair the performance of the Work

or otherwise materially diminish the value of the Work, then ▇▇▇▇▇▇ Mechanical shall not be required to perform the remedy elected by Owner unless Owner pays ▇▇▇▇▇▇ Mechanical the excess cost of performing such remedy over and above the cost of performing the remedy recommended by ▇▇▇▇▇▇ Mechanical. ▇▇▇▇▇▇ Mechanical shall in no case have any liability, under this warranty or otherwise, for any defect or deterioration which results from failure of Owner to provide any feedstock, utilities, or other supplies, services or conditions specified in Exhibit C, force majeure, improper operation or maintenance including damage caused by freezing, foreign substance or impurity introduced into the equipment, or any other matter not within ▇▇▇▇▇▇ Mechanical’s control or the control of its Design Consultants, Subcontractors, or others of those for whom ▇▇▇▇▇▇ Mechanical is responsible. Nothing in this warranty is intended to limit any manufacturer’s warranty which provides Owner with greater warranty rights than set forth in this Section 12.1 or the Contract. ▇▇▇▇▇▇ Mechanical will provide Owner with all manufacturer’s warranties upon Substantial Completion.

12.2 Desiccant Material: ▇▇▇▇▇▇ Mechanical warrants that the molecular sieve desiccant will not deteriorate due to mechanical abrasion to such an extent as to reduce the dehydration capacity of the molecular sieve below the level specified in the Performance Guarantee set forth at Exhibit D for a period of five years from the earlier of twelve (12) months from the completion of the Performance Test or eighteen (18) months from the date of Mechanical Completion. OWNER’S SOLE AND EXCLUSIVE REMEDY UNDER THIS WARRANTY SHALL BE REPLACEMENT OF THE DESICCANT MATERIAL AS PROVIDED IN THIS SECTION 12.2. Replacement shall be made at no cost to Owner in the event of a claim under this warranty within one year after Final Acceptance. With respect to any claim made thereafter, the desiccant replacement cost to Owner shall be pro rated, on a daily basis, on the basis of the number of days remaining in the last four (4) years of the warranty period. As an example, Owner would pay 50% of the cost of replacement desiccant if the original desiccant had to be replaced exactly three .(3) years from the commencement of the warranty period (100% x 730th day/ 1460 total Days).

12.3 Services: ▇▇▇▇▇▇ Mechanical warrants, for a period ending one year after Substantial Completion, or the last date on which ▇▇▇▇▇▇ Mechanical performed work under this Contract if this Contract is terminated for any reason prior to Final Acceptance, that the services provided by it hereunder will be provided with reasonable skill and care of the type normally exercised by other design professionals under similar circumstances. ▇▇▇▇▇▇ Mechanical

shall not have any obligation or liability for failures or defects due to ordinary wear and tear, corrosion or erosion, or as a result of improper operation, improper maintenance or operating conditions more severe than, or different from, those contemplated in the original design of the Work. EXCEPT AS PROVIDED OTHERWISE IN THIS CONTRACT OR OTHER AGREEMENT, OWNER’S SOLE AND EXCLUSIVE REMEDY IN CASE OF BREACH OF THIS WARRANTY SHALL BE TO HAVE ▇▇▇▇▇▇ MECHANICAL REPERFORM THE SERVICES FOUND NOT TO SATISFY THIS WARRANTY.

12.4 Notice of Warranty Claim: Owner shall notify ▇▇▇▇▇▇ Mechanical of any defect covered by the warranty set forth in Section 12 and Exhibit D as provided at Exhibit D, and shall notify ▇▇▇▇▇▇ Mechanical in writing of any defect covered by any other warranty within thirty (30) Days after discovering such defect, and in no case later than thirty (30) Days after expiration of the applicable warranty period. Any claim for breach of warranty not made in writing within the time prescribed in this Section 12 shall be deemed waived. In the event that the Owner has a claim based solely on the acts or omissions of Delta-T or the performance of Delta-T specified/furnished equipment, then the Owner agrees to pursue a claim directly against Delta-T and/or the supplier of the equipment and accept whatever, if anything, that it recovers with regard to such claim in total satisfaction of the claim. To the extent necessary, ▇▇▇▇▇▇ Mechanical will provide the Owner with an assignment of any of ▇▇▇▇▇▇ Mechanical’s rights necessary for the Owner to pursue such claims. This limitation on ▇▇▇▇▇▇ Mechanical’s liability shall not relieve ▇▇▇▇▇▇ Mechanical from the obligation to construct the Work as required by the Project plans and specifications. Notwithstanding anything to the contrary in this Section 12.6, in no event shall Delta-T’s cumulative liability to Owner and ▇▇▇▇▇▇ Mechanical exceed the sum of $*.

12.5 Correction of Defective Work:

12.5.1 ▇▇▇▇▇▇ Mechanical agrees to correct any Work that is found not to be in conformance with the Contract, including that part of the Work subject to Section 12.1 hereof, within a period of one year from the date of Substantial Completion of the Work or any portion of the Work, or within such longer period to the extent required by the Contract.

12.5.2 ▇▇▇▇▇▇ Mechanical shall, within two (2) days of receipt of written notice from Owner that the Work is not in conformance-with-the-Contract take meaningful steps to commence correction of such nonconforming Work, including the correction, removal or

replacement of the nonconforming Work and any damage caused to other parts of the Work affected by the nonconforming Work. If ▇▇▇▇▇▇ Mechanical fails to commence the necessary steps within such two (2) day period or to complete the necessary steps as soon as possible, Owner, in addition to any other remedies provided under the Contract, may provide ▇▇▇▇▇▇ Mechanical with written notice that Owner will commence correction of such nonconforming Work with its own forces. If Owner does perform such corrective Work, ▇▇▇▇▇▇ Mechanical shall be responsible for all reasonable costs incurred by Owner in performing such correction. If the nonconforming Work creates an emergency requiring an immediate response, the two (2) day periods identified herein shall be deemed inapplicable and ▇▇▇▇▇▇ Mechanical shall commence correction immediately.

12.5.3 The one year period referenced in Section 12.1 above and 12.7.1 above applies only to ▇▇▇▇▇▇ Mechanical’s obligation to correct nonconforming Work and is not intended to constitute a period of limitations for any other rights or remedies Owner may have regarding ▇▇▇▇▇▇ Mechanical’s other obligations under the Contract.

12.5.4 Prior to Final Completion, and as a condition to its approval by Owner, ▇▇▇▇▇▇ Mechanical shall deliver the as-built drawings and specifications with four (4) additional paper copies, arranged in proper order, indexed, and certified as accurate to Owner. Prior to the application for Final Payment, ▇▇▇▇▇▇ Mechanical shall provide any updated as-built drawings or specifications as may be required in the same manner and with the same number of copies.

13. Transfer of Title and Risk of Loss

Title to, and risk of loss of, the Equipment or any part thereof and all materials and components used, or to be used in the Plant, shall pass to Owner upon ‘delivery to the Work site. This provision, however, shall in no case be deemed to alter any of the rights or obligations of any party under any insurance policy provided under this Contract, or any waiver of subrogation set forth in Section 14 below.

14. Insurance; Bonds

14.1 Required Insurance: Each Party shall carry the insurance coverage described- in this Article 14 as insurance to be carried by it.

14.3 Waiver of Subrogation: Owner and ▇▇▇▇▇▇ Mechanical intend that all builder’s risk policies purchased, or required to be purchased, in accordance with this Contract Will protect Owner, ▇▇▇▇▇▇ Mechanical and all subcontractors at any tier, and will provide primary coverage for all losses and damages caused by the perils or causes of loss covered thereby. Owner and ▇▇▇▇▇▇ Mechanical waive all rights against each other and their respective subcontractors, officers, directors, agents and employees of the other arising out of or resulting from any of the perils or causes of loss covered by such policies and any other property insurance during the period prior to Final Completion and payment of all amounts due to ▇▇▇▇▇▇ Mechanical under this Contact. None of the above waivers shall extend to the rights that any Party making such waiver may have to the proceeds of insurance held by Owner as trustee or otherwise payable under any policy so issued. In addition, Owner waives all rights against ▇▇▇▇▇▇ Mechanical, its subcontractors at any tier and the officers, directors and employees and agents of any of them for business interruption and any other consequential damages caused by, arising out of or resulting from any such insured perils or causes of loss. All policies required under the Contract shall be endorsed to include such waivers of subrogation, or confirmation of such waivers shall appear on the certificates of insurance required to be delivered under Section 14.4 below. Owner and the ▇▇▇▇▇▇ Mechanical shall require from each of their contractors and subcontractors who do work on the Project similar waivers, each in favor of the other parties enumerated in this Section.

14.4 Certificates of Insurance: Before commencing the Work, ▇▇▇▇▇▇ Mechanical and Owner shall each furnish the other with certificates evidencing the coverage required under this Article 14 from the insurance company or companies carrying the aforesaid coverage. These certificates will provide that the policies may not be amended or terminated unless at least thirty (30) days prior written notice is given to Owner and ▇▇▇▇▇▇ Mechanical.
