Exhibit 10.10

DISCRETIONARY AND DEMAND

LINE OF CREDIT AGREEMENT

This Discretionary and Demand Line of Credit Agreement (the “Agreement”) is dated as of October 15, 2025, between HOLTEC INTERNATIONAL, a corporation organized under the laws of the State of Delaware (“Borrower”) and BMO BANK N.A. (“Bank”). The Borrower has applied for, and the Bank has approved the establishment of, a discretionary and demand revolving line of credit facility (the “Loan Facility”) from which the Borrower may from time to time request loans up to the maximum aggregate principal amount of $50,000,000.00 in United States Dollars (the “Maximum Credit”). Subject to the terms and conditions set forth herein, the Borrower may borrow and reborrow under the Loan Facility up to the Maximum Amount and may make principal payments on the outstanding principal of the Loan Facility at any time and in any amount. This Agreement, and the Loan Facility established hereunder, is an uncommitted, discretionary credit facility due and payable on demand by Bank. The Borrower hereby acknowledges and agrees that the Bank, in the Bank’s exercise of the Bank’s sole and absolute discretion may make or decline to make advances under the Loan Facility from time to time.

Section 1. Using the Account. All loans and advances under the Loan Facility are referred to in this Agreement as “Loans;”. Loan requests shall be sent to the Borrower’s BMO Bank Account Officer designated from time to time by Bank in writing to Borrower and may be made by writing or by telephone. As of the date hereof, the Borrower’s “BMO Bank Account Officer” is Jill Alvarez, with an address at 501 E Kennedy Blvd, Tampa, FL 33602, with telephone # (727)-481-4444 and e-mail address at jill.alvarez@bmo.com. In addition to any approvals or other requirements Bank deems necessary (in its sole discretion) to honor a Loan request, Bank may (but shall not be required to) verify any Loan request through its authentication process (or by any other means it deems necessary in its sole discretion to authenticate such Loan request) before funding such requested Loan. Loan proceeds shall be credited to the Borrower’s primary deposit account at the Bank, unless the Bank is directed otherwise by written directions from the Borrower in a form acceptable to the Bank. The proceeds of the Loan Facility may only be used by the Borrower for working capital purposes in the ordinary course of business and in accordance with the terms of this Agreement. Without limiting the foregoing, in no event may the proceeds of the Loan Facility be used for Borrower’s capital expenditures, acquisitions of the equity or assets of any business unit or entity or for making any dividends or distributions. The amount of each Loan requested shall be at least in a minimum principal amount equal to $100,000; and, without limiting the discretionary and demand nature of the Loan Facility, the Bank shall have the right to refuse to honor any Loan requested by the Borrower which is less than such minimum amount, even if the Bank has previously honored a Loan request for less than such minimum amount. The Borrower shall not request any Loan which, when taken together with the Loans then outstanding, would exceed the Maximum Credit. Upon request, the Borrower promises to furnish the Bank a duly executed and completed Form U-1 statement and agrees that the proceeds of Loans from the Loan Facility will not be used to purchase or carry stock, convertible bonds or warrants unless the Borrower has obtained the prior written consent of the Bank.

All Loans shall be made against and evidenced by the Borrower’s promissory note payable to the order of the Bank in a principal amount equal to the Maximum Credit, such note to be in the form of Exhibit A attached hereto (the “Note”). The Bank agrees that, notwithstanding the principal amount of the Note stated on its face, the Note shall evidence only the actual unpaid principal balance of Loans made under the Loan Facility. The Borrower agrees that in any action or proceeding instituted to collect or enforce collection of the Note, the amount shown as owing the Bank on its records shall be prima facie evidence of the unpaid balance of principal and interest on the Note.

Section 2. Interest. The outstanding principal balance of the Loans shall bear interest (which the Borrower hereby promises to pay) at the rate per annum determined by adding 0.75% per annum (the “Margin”) to the SOFR Rate as in effect from time to time, provided that if the Loans or any part thereof are not paid when due (whether by demand or otherwise), the Loans shall bear interest, whether before or after judgment, until payment in full thereof at the rate per annum determined by adding 2.00% to the interest rate which would otherwise be applicable thereto. Interest on the Loans shall be payable in arrears on the first business day of each month in each year; and interest shall also be due and payable upon demand. Interest on the Loans shall be computed on the basis of a year of 360 days for the actual number of days elapsed. The SOFR Rate (without inclusion of the Margin) shall initially be equal to [_]%per annum on the date hereof, and thereafter the SOFR Rate shall be reset on the first business day of every month occurring after the date hereof (herein a “Change Date”) and remain in effect until the next Change Date.

For purposes hereof, the following terms shall have the following meanings:

“Benchmark Transition Event” means the occurrence of any of the following events with respect to the SOFR Rate (as determined by the Bank in its sole discretion): (a) the SOFR Rate is no longer available, representative or published, (b) a regulatory supervisor for the administrator of the SOFR Rate or a governmental authority having jurisdiction over the Bank has made a public statement that the SOFR Rate shall no longer be made available, representative, used or advisable for detennining interest rates of loans; (c) loans are currently being executed containing, or loans that include benchmark replacement language similar to that contained in this Agreement are being executed or modified (as applicable) to incorporate or adopt, a new benchmark interest rate to replace tenn SOFR referred therein.

“SOFR Rate” means, for any day, the one-month forward looking secured overnight financing rate as administered by the CME Group Benchmark Administration Limited (CBA) (or a successor administrator selected by Bank) as quoted for the day that is two (2) U.S. governmental securities business days prior the Change Day. If the SOFR Rate as so determined would be less than 0.00%, the SOFR Rate will be deemed to be 0.00% for the purposes of this Agreement. Notwithstanding anything to the contrary herein, after the occurrence of a Benchmark Transition Event, the Bank may select an alternative index rate to replace the SOFR Rate as the benchmark interest rate hereunder (such rate to be selected in Bank’s sole discretion) and may make any technical, administrative or operational changes to this Agreement and any other loan documents, and may make any adjustments to interest rate spreads, to reflect the adoption and implementation of the substitute index rate and to permit the administration thereof by the Bank, and any amendments to this Agreement or any other loan documents reflecting such conforming changes will be effective without any further action or consent from Borrower.

The Bank shall determine the interest rate applicable to the Loans based on the foregoing, and its determination thereof shall be conclusive and binding except in the case of manifest error. The interest rate payable under this Agreement shall be subject, however, to the limitation that such interest rate shall never exceed the highest rate which the Borrower may contract to pay under applicable law

-2-

Section 3. Fees. In addition to any other amounts due hereunder, if any payment due hereunder is not received by the Bank on or before 1 :00 p.m. (Chicago time) of the tenth ( 10th) day after such payment is due, the Borrower shall pay to the Bank on demand a late fee equal to the greater of (i) five percent (5%) of the amount due and (ii) $15.00. Since this is an uncommitted credit arrangement, no commitment or similar fee will be charged.

Section 4. Payments. All payments shall be made to the Bank at its office at 320 South Canal Street, Chicago, Illinois, (or at such other place as the Bank may specify) no later than 1:00 p.m. (Chicago time) on the date any such payment is due and payable. All such payments shall be made in lawful money of the United States of America, in immediately available funds at the place of payment, without set-off or counterclaim and without reduction for, and free from, any and all present or future taxes, levies, imposts, duties, fees, charges, deductions, withholdings, restrictions, and conditions of any nature imposed by any government or any political subdivision or taxing authority thereof (but excluding any taxes imposed on or measured by the net income of the Bank). The Borrower hereby irrevocably authorizes the Bank to charge from time to time any of the Borrower’s deposit accounts with the Bank and/or make Loans from time to time hereunder, in each case for payment of any amounts then due and payable hereunder (whether for interest then due or otherwise); provided that the Bank shall not be under any obligation to charge any such deposit account or make any such Loan, and the Bank shall incur no liability to the Borrower or any other person or entity for its failure to do so. Payments received by the Bank shall be applied first to accrued interest then due and then to the principal balance of outstanding Loans unless otherwise directed, provided that after demand all payments received shall be applied in such order and manner as the Bank shall determine. If any payment from the Borrower under this Agreement becomes due on a Saturday, Sunday or a day which is a legal holiday for banks in the State of Illinois, Georgia or Florida, such payment shall be made on the next bank business day and any such extension shall be included in computing interest under this Agreement.

Section 5. Representation and Warranties. In consideration of establishing and maintaining the Loan Facility, the Borrower hereby represents and warrants to the Bank on the date of this Agreement, and on each date that credit is to be extended hereunder, that: (a) the Borrower is duly organized, validly existing, and in good standing under the laws of its state of organization; (b) the execution, delivery, and performance by the Borrower of this Agreement and the Note are within its powers, have been duly authorized by all necessary action, and do not contravene the Borrower’s organizational documents (e.g., charter, articles of incorporation and by-laws, articles of association and operating agreement, partnership agreement or any similar organizational documents) or any law or contractual restriction binding on or affecting the Borrower; (c) no authorization or approval or other action by, and no notice to or filing with, any governmental authority or regulatory body is required for the Borrower’s due execution, delivery, and performance of this Agreement or the Note; (d) this Agreement is, and the Note when executed and delivered by the Borrower will be, the Borrower’s legal, valid, and binding obligation enforceable against the Borrower in accordance with its terms; (e) the Borrower is not engaged in the business of extending credit for the purpose of purchasing or carrying margin stock (within the meaning of Regulation U issued by the Board of Governors of the Federal Reserve System), and no proceeds of the Loans will be used to purchase or carry any margin stock or to extend credit to others for the purpose of purchasing or carrying
