You must use our required business computer systems, which we may periodically change. Currently, we require you to use OnQ, which connects System Hotels to Hilton’s reservation offices and travel planners worldwide. For OnQ you must have certain hardware, software, installation, and support. We also require you to use our required Guest Internet Access System. For Guest Internet Access you must have certain hardware, software, an internet access circuit, and internet service. In addition, you must have the Connected Room system, the GRO system, the Delphi.fdc system, a Digital Floor Plan, and Digital Key system that meet our Standards and specifications. All of these components must be acquired from either HSS or preferred providers, or may be acquired from other (non-preferred) vendors, depending on the specific product or service and the individual circumstances of your Hotel. We will provide you with our Standards and specifications as appropriate, but we do not issue Standards or technical specifications that are proprietary or confidential without protections in place that we deem sufficient (such as vendor confidentiality agreements). At certain times there might be only one approved or preferred vendor for certain hardware components or software applications, such as the GRO system, the Delphi system, and if your system uses the PEP property management system, the PEP local exchange gateway (LEG) device. See Items 5, 6, and 11 for details. In the future, any of the products or services may be manufactured or provided by an approved supplier who is also our client or supplier. See Item 8 above regarding HSS and other affiliate revenues related to the required business computer systems.

We may require you to install our “Connected Room” system, which provides an assortment of streaming apps and allows guests to control their guest room television using the Hilton Honors App. This system requires a control module that is connected to each in-room television along with certain electrical fixtures, which you must purchase from us or our approved vendors. The cost of this system is currently between $50,225 and $60,025, and the cost of the electrical fixtures is competitive with equivalent standard fixtures. The initial installation costs are paid to the vendor before opening. You must also have maintenance and support from us or an approved vendor, which is paid to us and currently costs between $893 and $1,283 per month ($10,716 to $15,396 per year). These costs are normally not refundable. Delphi System You must use Delphi.fdc, a cloud-based sales and events system powered by Amadeus Hospitality, in a configuration we approve. The set-up costs of this system are between $990 and $41,000. Additional set-up costs may apply, depending on the implementation approach you choose and the specific needs of your Hotel. You will pay the set-up costs to the vendor directly. You must also pay annual license fees and maintenance costs of $858 per user per year. You will pay all Delphi system fees to HSS, which are passed through to the vendor. The optional on- property license fee includes a mark-up of up to 12%, which we keep to help cover our costs in developing and maintaining the Delphi system for Network Hotels. Depending on your Hotel’s technology configuration, you may be required to utilize the MeetingBroker lead distribution platform, which integrates with Delphi.fdc and other group booking systems. MeetingBroker is also powered by Amadeus Hospitality. There are no separate fees for the MeetingBroker lead distribution platform, although you may be required to sign a separate license agreement with Amadeus Hospitality to use it. We are not obligated to provide any maintenance or updates for either of these systems. You must maintain and update them at your cost to remain in compliance with the Standards. There are no limits on the frequency or cost of this obligation. We will have independent access to your Hotel’s event sales information stored in these systems (including accounts, inventory, bookings and other data). There are no contractual limitations on our right to access this information.

Hilton’s Advance Purchase Program provides guests with the ability to pay for hotel reservations in advance in exchange for receiving a discounted room rate. You may but are not required to participate in this optional program. Currently, we charge a fee of 4.5% of the advance payments received (“Advance Purchase Fee”). Guests typically make advance payments using their credit or debit cards. In 2024, we rolled out an enhancement to this program that permits guests to make payments with certain third-party digital payment apps and online services such as Google Pay and Apple Pay. The third-party apps/payment providers may change over time. If you choose to participate in the Advance Purchase Program you will be required to offer digital payments as an option to your guests. You must also open a merchant account and sign a Licensee Merchant Agreement with a third-party vendor called Adyen N.V. (“Adyen”) and a Refund Authorization with us. Adyen provides electronic payment processing services for this program. Currently, you do not have to pay any additional fees to us or to Adyen to enroll in the digital payments option and the Advance Purchase Fee will be waived. However, Adyen may charge certain transaction, processing, or service fees that apply to your account. If you wish to participate in the Advance Purchase Program, we will provide complete details on request. We may modify this program and make this program or some of its components mandatory in the future.

You may acquire the hardware from our affiliate, HSS, or its preferred providers, or you may purchase or lease it from other (non-preferred) third-party vendors. You must acquire the OnQ software components from HSS or our designated vendors because certain elements are proprietary. The property management system component within the OnQ system is called the Hilton Property Management System ("HPMS”). HPMS may also be referred to as the Property Engagement Platform (“PEP®”). We developed HPMS in collaboration with HotelKey, Inc., a third- party technology company. Certain elements of HPMS are proprietary to Hilton. If you purchase the standard OnQ package from HSS, we estimate that it will cost within the range shown here for our prototype size of hotel shown in Item 7. This includes hardware, software, installation and certain other costs and fees, and is based on the size of the Hotel and number of workstations. We are not able to determine a separate market price for the OnQ system because there is no third-party market for OnQ in its entirety. See Item 11 for details.
