Upon the request of Borrower made at any time from and after the date hereof until the Termination Date, and so long as no Event of Default has occurred, Lender may, in its sole and absolute discretion, make Advances to Borrower under a revolving credit facility (the Revolving Credit Facility) in an amount up to:

(a)        eighty-five percent (85%) of the aggregate outstanding amount of Eligible Accounts (the Eligible Accounts Loan Value), so long as Dilution is less than three percent (3%); plus

(ii)       Five Million Dollars ($5,000,000); and

provided, however, in no event at any time shall the maximum aggregate principal amount outstanding under the Revolving Credit Facility exceed Eighteen Million Dollars ($18,000,000) (said dollar limit being, the Advance Limit). Lender may create reserves against, or reduce its advance percentages based on Eligible Accounts or Eligible Inventory without declaring an Event of Default if Lender determines, in its good faith discretion, that such reserves or reduction are necessary, without limitation, to protect Lender's interest in the Collateral and/or against diminution in the value of any Collateral and/or to insure that the prospect of payment or performance by Borrower of its Obligations to Lender are not impaired.

2.2     Overadvances. All Advances shall be added to and be deemed part of the Obligations when made. If, at any time and for any reason, the aggregate amount of the outstanding Advances under the Revolving Credit Facility exceeds the dollar or percentage limitations contained in Section 2.1 (any such excess being, an Overadvance), Borrower shall, upon demand by Lender, immediately pay to Lender in cash, the amount of any such Overadvance. Without affecting Borrower's obligation to immediately repay to Lender the amount of each Overadvance, if such Overadvance is not cured within two (2) Business Days after Lender's delivery to Borrower of a written demand therefor, Borrower shall pay Lender a fee (the Overadvance Fee) in an amount to be agreed upon between Lender and Borrower, but in any event, not less than $500.00 per occurrence of an Overadvance, plus interest on such Overadvance amount at the Default Rate set forth below. Further, without affecting Borrower's obligation to immediately repay to Lender the amount of each Overadvance, all Overadvances are deemed Obligations and are secured by the Collateral.

2.3     Authorization to Make Advances. Lender is hereby authorized to make the Advances based upon telephonic or other instructions received from anyone purporting to be an Authorized Officer, or, at the discretion of Lender, if such Advances are necessary to satisfy any Obligations. All requests for Advances shall specify the date on which such Advance is to be made (which day shall be a Business Day) and the amount of such Advance. Requests received after 12:00 p.m. Eastern time on any day shall be deemed to have been made as of the opening of business on the immediately following Business Day. All Advances made under this Agreement shall be conclusively presumed to have been made to, and at the request and for the benefit of, Borrower when deposited or otherwise disbursed in accordance with the instructions of Borrower or in accordance with the terms and conditions of this Agreement. Unless otherwise requested by Borrower, all Advances shall be made by a wire transfer to the Deposit Account of Borrower designated on Schedule 2.3 or to such other account as Borrower shall notify Lender in writing. Borrower shall pay to Lender a funds transfer fee of $35.00 for each Advance, which such fee shall be payable on the first (1st) calendar day of each month of the Term for all Advances made during the preceding month.

¹ Lender shall have the right to order an updated inventory appraisal every twelve (12) months thereafter or upon the existence of an Event of Default, in each case with all costs of any such inventory appraisal to be paid by Borrower.

2.4     Interest.

(a)     Except where specified to the contrary in the Loan Documents, interest shall accrue on the Daily Balance at the per annum rate of one and one-half percentage points (1.5%) above the Prime Rate in effect from time to time, but not less than four and three-quarters percent (4.75%) (the Applicable Rate). At the option of Lender, (i) from and after the occurrence of an Event of Default, and without constituting a waiver of any such Event of Default, and (ii) if the Obligations are not paid in full by the Termination Date, and without waiving the maturity of the Obligations on the Termination Date, the Obligations shall bear interest at the per annum rate of six percentage points (6%) above the Applicable Rate (the Default Rate). All interest payable under the Loan Documents shall be computed on the basis of a three hundred sixty (360) day year for the actual number of days elapsed on the Daily Balance. Interest as provided for herein shall continue to accrue until the Obligations are indefeasibly paid in full.

(b)     The interest rate payable by Borrower under the terms of this Agreement shall be adjusted in accordance with any change in the Prime Rate, from time to time, on the date of any such change. All interest payable by Borrower shall be due and payable on the first (1st) day of each calendar month during the Term. Lender may, at its option, add such interest, fees and charges payable by Borrower under the Loan Documents and all Lender Expenses to the Obligations, and the Obligations (as so increased by the amount of such interest, fees, charges and Lender Expenses), shall thereafter accrue interest at the rate then applicable under this Agreement. Notwithstanding anything to the contrary contained in the Loan Documents, the minimum monthly interest payable by Borrower on the Advances in any month shall be calculated on an average Daily Balance of Three Million Dollars ($3,000,000).

(c)     In no event shall interest on the Obligations exceed the highest lawful rate in effect from time to time. It is not the intention of the parties hereto to make an agreement which violates any applicable state or federal usury laws. In no event shall Borrower pay, nor shall Lender accept or charge, any interest which, together with any other charges on the principal or any portion thereof, exceeds the maximum lawful rate of interest allowable under any applicable state or federal usury laws. Should any provision of this Agreement or any existing or future Notes or Loan Documents between the parties be construed to require the payment of interest or any other fees or charges that could be construed as interest, which, with any other charges upon the principal or any portion thereof and any other fees or charges that could be construed as interest, exceed the maximum lawful rate of interest, then any such excess shall be applied to the remaining principal balance of the Obligations, if any, and any remainder shall be refunded to Borrower.

(d)     Notwithstanding any of the foregoing in this Section 2.4, for purposes of this Agreement, it is the intention of Borrower and Lender that interest shall mean, and be limited to, any payment to Lender which compensates Lender for (i) the extension of credit to Borrower and the availability to Borrower of the Revolving Credit Facility and (ii) any default or breach by Borrower of a condition upon which such credit was extended and such Revolving Credit Facility was made available. Borrower and Lender agree that for the sole purpose of calculating the interest paid by Borrower to Lender, it is the intention of Borrower and Lender that interest shall mean and include, and be expressly limited to, any interest accrued on the aggregate outstanding Daily Balance of the Obligations during the term hereof pursuant to subsections 2.4(a) and 2.4(b), any Overadvance Fee, Facility Fee (as defined below) and late fees charged to Borrower during the term hereof. Borrower and Lender further agree that it is their intention that the following fees shall not constitute interest: any Servicing Fees (as defined below), any Field Examination Fees (as defined below), any attorney fees incurred by Lender, any premiums or commissions attributable to insurance guaranteeing repayment, finders' fees, credit report fees, appraisal fees or fees for document preparation or notarization. To the extent however that New Jersey law excludes from the calculation of interest any fees defined herein as interest or includes as interest any fees or other sums which are intended not to constitute interest, New Jersey law shall supersede and prevail, and all such interest shall be subject to subsection 2.4(c) above.

2.5     Collection of Accounts. Lender or Lender's designee may at any time, with or without notice to Borrower, subject to the second sentence of this Section 2.5, (a) notify customers, Account debtors or other obligors of Borrower that the Accounts and other Collateral have been assigned to Lender and that Lender has a security interest therein and (b) collect the Accounts and other Collateral directly and add the collection costs and expenses thereof to the Obligations; provided, however, unless and until Lender takes such action or gives Borrower other written instructions, Borrower shall notify all Account debtors and other obligors of Borrower to remit payments on the Accounts and other Collateral to a lockbox to be designated by Lender, or in the case of payments to be made by wire transfer, ACH or other electronic means, to an account designated by Lender over which Lender shall have control. In the event Lender or Lender's designee provides notice to customers, Account debtors or other obligors of Borrower as provided for in this Section 2.5, Lender agrees that Lender will use its best efforts to notify Borrower of same within five (5) Business Days. All such payments remitted to the lockbox or made by wire transfer, ACH or other electronic means to the account designated by Lender shall then be credited to a deposit account of Lender into which remittances from Account debtors and other obligors of Borrower and obligors of other customers of Lender may be credited.

(i)     to Borrower and all other parties entitled to receive a notice of disposition under the Code, a notice in writing of the time and place of the public sale or other disposition, or if the sale or other disposition is a private sale or some other disposition other than a public sale, a notice in writing of the time on or after which the private sale or other disposition is to be made; and

9.3     Waivers. If Lender seeks to take possession of any of the Collateral by court process, Borrower hereby irrevocably waives: (a) any bond and any surety or security relating thereto required by any statute, court rule or otherwise as an incident to such possession; (b) any demand for possession prior to the commencement of any suit or action to recover possession thereof; and (c) any requirement that Lender retain possession of, and not dispose of, any such Collateral until after trial or final judgment.

9.4     Commercially Reasonable Sale. Borrower and Lender agree that a sale or other disposition of any Collateral which complies with the following standards will conclusively be deemed to be commercially reasonable (but nothing herein implies that other methods or manners of sale are not commercially reasonable): (a) notice of the sale is given to Borrower at least (10) ten days prior to the sale, and, in the case of a public sale, notice of the sale is published at least seven (7) days before the sale in a newspaper of general circulation in the county where the sale is to be conducted; (b) notice of the sale describes the Collateral in general, non-specific terms; (c) the sale is conducted at a place designated by Lender, with or without the Collateral being present; (d) the sale commences at any time between 8:00 a.m. and 6:00 p.m.; (e) payment of the purchase price in cash or by cashier's check or wire transfer is required; and (f) with respect to any sale of any of the Collateral, Lender may (but is not obligated to) direct any prospective purchaser to ascertain directly from Borrower any and all information concerning the Collateral.

If Borrower fails to pay any monies (whether taxes, assessments, insurance premiums or otherwise) due to third persons or entities, fails to make any deposits or furnish any required proof of payment or deposit or fails to perform any of Borrower's other covenants under any of the Loan Documents, then in its discretion and without prior notice to Borrower, Lender may do any or all of the following: (a) make any payment which Borrower has failed to pay or any part thereof; (b) set up such reserves in Borrower's loan account as Lender deems necessary to protect Lender from the exposure created by such failure; (c) obtain and maintain insurance policies of the type described in Section 6.10 and take any action with respect to such policies as Lender deems prudent; or (d) take any other action deemed necessary to preserve and protect its interests and rights under the Loan Documents. Any payments made by Lender shall not constitute: (i) an agreement by Lender to make similar payments in the future or (ii) a waiver by Lender of any Event of Default. Lender need not inquire as to, or contest the validity of, any such expense, tax, security interest, encumbrance or lien, and the receipt of notice for the payment thereof shall be conclusive evidence that the same was validly due and owing.

11.1     Demand, Protest. Borrower waives demand, protest, notice of protest, notice of default or dishonor, notice of payment and nonpayment, notice of any default, notice of intention to accelerate, notice of acceleration, and notice of nonpayment at maturity and acknowledges that Lender may compromise, settle or release, without notice to Borrower, any Collateral and/or guaranties at any time held by Lender.

Ladies and Gentlemen:

We understand that North Mill Capital LLC, a Delaware limited liability company ("NMC"), proposes to make loans and advances to Borrower (and its subsidiaries), which loans and advances are to be secured by a security interest in the personal property assets of Borrower (and its subsidiaries). As of the date hereof, Borrower is indebted to Pinnacle under a revolving credit facility and term loans heretofore made by Pinnacle to Borrower, which revolving credit facility and term loans are secured by the liens and security interests heretofore granted by Borrower to Pinnacle in Borrower's real and personal property. The real property is described in the real estate documents set forth on Exhibit A attached hereto (collectively, the "Real Estate Documents"), and the personal property assets are the subject of various UCC financing statements set forth on Exhibit B attached hereto (the "Pinnacle Financing Statements").

Pinnacle and Borrower acknowledge that payments by Borrower's account debtors are, if made by check, paid to a post office box of Borrower, and if made by ACH or wire transfer, remitted directly into Borrower's depository account at Pinnacle. Borrower remits payment to Pinnacle under the revolving credit facility and term loans on a monthly basis.

Borrower is indebted to Pinnacle on the date hereof in the following amounts with respect to the revolving credit facility only:

This payoff is based on the principal balance above and may not include any unposted loan payments or advances processed after the date hereof. 

In addition, Borrower must forward signed closing instructions to Borrower's Financial Advisor at Pinnacle via mail, email or fax number to close Borrower's loan account. Borrower should include its name, loan number and the desired closing date.

Payment to Pinnacle of the Total Revolver Payoff Amount shall be made by wire transfer as follows:

[REDACTED WIRE INSTRUCTIONS]

The aforesaid Total Revolver Payoff Amount shall only apply if Pinnacle receives a wire transfer of the aforesaid Total Revolver Payoff Amount on or before 5:00 p.m. (Eastern time) on July 24, 2020. If payment is to be made thereafter, kindly contact us for a current payoff amount.

Effective upon Pinnacle's confirmation to NMC that Pinnacle is in receipt of the Total Revolver Payoff Amount:

(a)     The Credit Agreement shall be terminated;

(b)     Pinnacle's liens upon and security interests in the personal property assets of Borrower shall be terminated, and NMC shall be authorized to file the UCC termination statements with respect to Pinnacle Financing Statements (and as any and all other UCC financing statements against Borrower on which Pinnacle is the secured party), and Pinnacle shall execute and deliver to NMC such other documents as NMC may reasonably request to release Pinnacle's liens of record, if any, against the personal property assets of Borrower, all costs and expenses incurred in connection therewith to be paid by Borrower. For the avoidance of doubt, Pinnacle acknowledges and agrees that the only loan documents that will continue with regard to the remaining obligations of Borrower to Pinnacle (that is under the term loans made by Pinnacle to Borrower, the "Term Loans") will be the notes set forth on Exhibit C attached hereto and the Real Estate Documents, and the only remaining collateral security that Pinnacle holds for the Term Loans is the real property described in in the Real Estate Documents and the fixtures of Borrower, and that with respect to any grant of a lien upon/security interest in the equipment of Borrower, as set forth in the Real Estate Documents (or otherwise), notwithstanding any wording to the contrary therein, is deemed to be against the fixtures of Borrower attached to the real property only, and not against personal property equipment of Borrower and no further financial covenants shall apply to the Term Loans; and

(c)     Pinnacle confirms there is no automatic sweep from Borrower's depository account, and Borrower shall make all payments under the Term Loans directly to Pinnacle.

By its execution of this payoff letter below, until Borrower's account debtors have been notified to make payments on Borrower's accounts receivable to the lockbox and/or blocked account designated by NMC and the cash has been so transitioned to said lockbox/blocked accounts, Borrower agrees to provide NMC with a daily screen shot of Borrower's depository account at Pinnacle (and the other financial institutions where payments on Borrower's account receivables have been received), and Borrower shall (a) forward to directly NMC at the address set forth on Exhibit D attached hereto on a daily basis by reputable overnight carrier all checks received by Borrower at Borrower’s headquarters or in Borrower's post office box, and (b) advise Pinnacle to send by wire transfer to the blocked account designated by NMC and set forth on Exhibit D, all wires/ACH payments received in Borrower's depository account at Pinnacle.

Pinnacle acknowledges to Borrower and NMC that, after payment of the Total Revolver Payoff Amount and termination of the Credit Agreement, no defaults or Events of Default currently exist under the notes evidencing the Term Loans and/or the Real Estate Documents.

Kindly indicate your acceptance of the terms of this letter by signing in the space provided below. This letter may be executed in counterparts and by facsimile or other electronic transmission with each such counterpart, facsimile or other electronic transmission constituting a valid, effective and enforceable agreement. 

If Borrower has any questions regarding this payoff letter, please contact me at [REDACTED PHONE NUMBER].

Thank you for allowing Pinnacle to serve you.

Acknowledged and Agreed to:

NORTH MILL CAPITAL LLC

Borrower hereby (a) acknowledges that it is indebted to Pinnacle in the amounts set forth above, which sums are due and owing without defense, setoff, or counterclaim, (b) acknowledges that the Credit Agreement between Pinnacle and Borrower is terminated and (c) agrees to the terms of the aforesaid payoff letter.
