1. OFFER FOR SALE.

All agreements between the Buyer and GERSTEL to purchase the Products and/or Services shall be governed by the terms and conditions herein. The Buyer and GERSTEL agree that any modifications, changes, alterations of the terms and conditions herein must be in writing and signed by the Buyer and GERSTEL. GERSTEL hereby objects to any additional or different terms which may be contained in any of the Buyer’s purchase orders, acknowledgements or other documents or any communications received from the Buyer, and the Buyer and GERSTEL hereby agree that any such attempts shall be null and void and not deemed a part of the terms and conditions hereunder or any resulting order. All purchase orders must reference the applicable GERSTEL quotation number.

Any offer hereunder shall expire thirty (30) days following its date, unless the Products and/or Services are provided by GERSTEL and accepted by the Buyer. No order may be cancelled, modified or altered by the Buyer, without written consent of GERSTEL, which may be withheld in its sole discretion.

2. PRICE AND PAYMENT TERMS.

The prices for the Products and Services are based on GERSTEL’s current prices, in effect at the time of order, for the Products and Services. All prices for Products and Services are in United States dollars. All current prices are subject to change by GERSTEL at any time without prior notice.

All payments for the Products and the Services are payable in only United States Dollars. The Buyer shall make
payment as follows, unless GERSTEL requires payment in advance or upon different terms:

(i) for orders greater than or equal to One Hundred Thousand Dollars ($100,000.00) in the aggregate,
payment of fifty percent (50%) of the amount due at the time of order and payment of the balance of the amount due within thirty (30) days following the date of invoice, or
(ii) for orders less than One Hundred Thousand Dollars ($100,000.00) in the aggregate, payment within thirty
(30) days following the date of invoice.

Payments for all Products and Services are due as set forth above, regardless of whether or not the installation of such Products and Services has been completed.

In the United States of America, payments may be made only in cash or by wire transfer or by automated clearing house (“ACH”) transfer or by certain credit cards. In Canada, payments may be made only in cash or by ACH transfer or by certain credit cards.

Notwithstanding the foregoing, for all countries other than the United States of America and Canada, the Buyer shall make payment in full in advance by wire transfer or by ACH transfer or by certain credit cards.

Notwithstanding the foregoing, at its option at any time, GERSTEL may require the Buyer to make payment by
irrevocable letter of credit or by promissory note secured by purchase money security interest, upon terms and
conditions satisfactory to GERSTEL in its sole discretion, and GERSTEL may defer shipment or cancel any order if the Buyer does not promptly provide such payment.

To assure proper credit to the Buyer’s account, the Buyer is encouraged to send payment notifications, together with the applicable invoice number, to GERSTEL via email at finance@gerstelus.com or such other mail as directed by GERSTEL.

Charges will be assessed on past due accounts as follows: (i) a late charge at a rate equal to the lesser of one and one- half percent (1.5%) each month or the highest rate permitted by applicable law and (ii) reasonable collection costs and expenses, including attorneys’ fees and court costs. The Buyer’s failure to pay in accordance with the provisions of this Section 2 shall entitle GERSTEL, without prejudice to its rights to damages, to suspend or cancel any outstanding orders or require further assurance of payment from the Buyer.

3. TAXES AND OTHER CHARGES.

The Buyer shall pay, in addition to the prices as set forth herein, any and all manufacturer’s tax, occupation tax, use tax, property tax, sales tax, excise tax, value-added tax, duty, custom, inspection or testing fee, or any other tax, fee or charge of any nature whatsoever, except for taxes on GERSTEL’s income, imposed by any governmental authority on or measured by the transaction between GERSTEL and the Buyer. The Buyer shall indemnify, defend and hold harmless GERSTEL against all claims, losses, damages, liabilities, costs and expenses, including reasonable attorneys’ fees, to the extent such claims arise out of any breach of this Section.

4. DELIVERY.

The Products shall be delivered, unless otherwise agreed to by the parties, freight on board place of shipment upon delivery to the carrier designated by GERSTEL at GERSTEL’s plant in Linthicum, Maryland USA. The Buyer shall be responsible for all transportation expenses from GERSTEL’s plant or other loading point, and the Buyer agrees that such expenses shall be included on the applicable invoice for Products. Delivery of the Products to a carrier at GERSTEL’s plant or other loading point shall constitute delivery to the Buyer; and regardless of shipping terms or freight payment, all risk of loss or damage in transit shall be borne by the Buyer.

GERSTEL reserves the right to make delivery in partial installments, unless otherwise expressly stipulated herein. All such partial installments will be separately delivered and paid for when due, without regard to subsequent deliveries. Any delay in delivery of any partial installment shall not relieve the Buyer of its obligation to accept remaining deliveries.

The Buyer acknowledges that all delivery dates are approximate. In no event shall GERSTEL be liable for any delays in delivery of the Products and/or Services.

The method and route of shipment shall be at the discretion of GERSTEL unless the Buyer shall specify otherwise and pay for any such additional expense.

5. INSPECTION UPON RECEIPT AND RETURNS.

The Buyer must examine the Products when they are received by the Buyer; provided however, that the Buyer must examine the system level Products only after the packaging for such Products is opened by the GERSTEL representative who will install such Products. The Buyer shall make any and all claims for shortages, defects or other errors in delivery in writing to GERSTEL within thirty (30) days of receipt of shipment. Failure to give such notice shall constitute unqualified acceptance of all shipments made prior to GERSTEL’s receipt of the Buyer’s notice of such claims, and shall constitute a waiver of all such claims by the Buyer. Any and all claims for loss or damage to the Products in transit should be made directly to the carrier and not to GERSTEL.

To make any return of the Products to GERSTEL, the Buyer must obtain a return merchandise authorization number by contacting GERSTEL, at (410) 204-7259 or service@gerstelus.com or such other emails directed by GERSTEL, prior to returning any Products to GERSTEL. The Buyer shall pay all costs and expenses related to, and bear the risk of loss and damage for, shipping of returned Products to GERSTEL. GERSTEL’s restocking fees shall apply to all returns. Any returns made on a cash on delivery basis or without a return merchandise authorization number may be refused by GERSTEL, in its sole discretion.

6. TITLE.

Notwithstanding the passing of the risk of loss and damage from GERSTEL to the Buyer as described herein, GERSTEL shall retain title to the Products until it has received payment in full of all such amounts owed by the Buyer to GERSTEL due in connection with the Products delivered hereunder or any other account. Notwithstanding the foregoing, all software products shall be licensed to Buyer subject to the terms and conditions of the applicable license agreement,

7. STORAGE.

If the Products ordered by the Buyer are not shipped within fifteen (15) days after notification to the Buyer that the Products are ready for shipment for any reason beyond GERSTEL’s reasonable control, including without limitation, the Buyer’s failure to give shipping instructions, GERSTEL may store the ordered Products at the Buyer’s risk in any warehouse or yard or upon GERSTEL’s premises, and the Buyer shall immediately pay all handling, transportation and storage charges at the prevailing commercial rates upon submission of invoices by GERSTEL for such handling, transportation and storage charges.

8. CHANGES TO PRODUCTS.

GERSTEL reserves the right to make, at any time, changes in design and construction of the Products or in the scope of the Services as GERSTEL deems appropriate, without prior notice to the Buyer; provided that such changes do not have a material adverse affect on the Products and/or the Services. For example, GERSTEL may provide to the Buyer products and/or services that have the functionality and performance of the Products and/or the Services that the Buyer ordered, but changes in what is provided and what is described in a specification sheet, catalog or description of the Products and/or Services are possible. GERSTEL may furnish suitable substitutes for materials unobtainable because of priorities or regulations established by governmental authority or non-availability of materials from suppliers.
