Founded with the mission to make sports equipment safer, better and easier to use, Riddell continues to address the evolving protective equipment needs of the athlete. Today, Riddell equipment is seen on football fields from coast-to-coast, protecting every level of playerfrom youth athletes to NFL professionals. Riddell is always working on the next generation of helmet technology. Its newest product introduction, the Riddell InSite Impact Response System, is the latest in a series of recent innovations incorporating state-of-the-art features that are new to the football field. Riddell InSite is a new integrated monitoring and alerting tool designed specifically for the proactive protection of football players. As the first to implement head impact monitoring and recording systems, Riddell developed InSite using data collected by Riddells Sideline Response System (SRS) with Head Impact Telemetry (HITS). Since 2004, Riddell SRS has analyzed millions of impacts from youth to elite football competition, and its data has led to impactful changes to rules, how the game is played and coached, and has informed new helmet designs with enhanced protective benefits. Riddell InSite utilizes new integrated technology to monitor and record significant head impacts sustained during a football game or practice. Coaches and other sideline staff will now have Riddell InSites unique vantage point of what goes on inside the helmet at the time of contact. InSite is designed to alert team staff of high risk single and multiple head impacts, and enable improved identification and management of concussion. You must read this User Guide completely before set-up and use of the InSite Impact Response System. If you need assistance with use of the system, please contact InSite Customer Support at (800) 725-5338 or insitehelp@riddellsports.com. At Riddell, improving athlete protection remains paramount. Helmet technology innovations such as InSite underscore Riddells commitment to designing and manufacturing the best protective equipment for football players at all levels. P/N XXXXX vX.XX Page | 3 WARNINGS Contact in football may result in CONCUSSION-BRAIN INJURY which no helmet can prevent. Symptoms include: loss of consciousness or memory, dizziness, headache, nausea or confusion. If you have symptoms, immediately stop playing and report them to your coach, trainer and parents. Do not return to a game or practice until all symptoms are gone and you have received MEDICAL CLEARANCE. Ignoring this warning may lead to another and more serious or fatal brain injury. Do not use your helmet to butt, ram or spear an opposing player. This is in violation of the football rules and such use can result in severe head or neck injuries, paralysis or death to you and possible injury to your opponent. NO HELMET CAN PREVENT HEAD OR NECK INJURIES A PLAYER MIGHT RECEIVE WHILE PARTICIPATING IN FOOTBALL. Riddell InSite alerts the sideline to significant, single or multiple impacts that MAY result in a concussion or other head injury. Riddell InSite is NOT a medical device. Riddell InSite is NOT a protective device. RIDDELL INSITE DOES NOT DIAGNOSE CONCUSSIONS OR OTHER HEAD INJURIES AND IS NOT INTENDED TO BE USED AS A DIAGNOSTIC DEVICE. Serious injury and/or concussion may occur even if no alert is reported. Riddell InSite transmits alerts at research-based thresholds; however, concussion may occur at impacts below these thresholds. Riddell InSite is intended to be used as a supplement to a teams concussion protocol. Riddell InSite should not be used to replace the existing Safety Plans and Concussion protocols the team, school or organization has in place. In all instances when the Alert Monitor signals an Alert, staff should execute its concussion assessment protocol. The Centers for P/N XXXXX vX.XX Page | 4 Disease Control (CDC, www.cdc.gov/concussion) and USA Football

(http://usafootball.com/health-safety/concussion-awareness) offer concussion management guidelines. Riddell InSite must be properly installed and configured by the user to allow for correct function and transmission of impact Alerts (see Setup Summary for installation instructions). For proper performance, the Riddell Sideline Monitor (RSM) must be used within fifty (50) yards of the instrumented players (see During Play Using Alerts, p.45, for more information). If a Player Unit generates an Alert outside the communication range of fifty yards, the Alert is saved and transmitted when the equipment is again within range. DO NOT MODIFY, CHANGE, OR ALTER THE DEVICE IN ANY WAY. Player units must be reconditioned annually to ensure proper performance. For questions regarding Riddell InSite or reconditioning:

o Email insitehelp@riddellsports.com P/N XXXXX vX.XX Page | 5 PRODUCT OVERVIEW The InSite Impact Response System for Axiom is composed of the following components:

1. InSite Axiom Player Unit (included with new helmet purchase, or retrofit package sold separately) 2. USB Cable and AC Charger 3. Riddell Sideline Monitor INSITE AXIOM PLAYER UNIT Player Units installed within Riddell helmets measure impacts as they occur on field. When an impact exceeds a predetermined threshold specific to the players level of play and playing position, an Alert is sent wirelessly to the Riddell Sideline Monitor on the sidelines. The athletes playing position and level of play are selected by the InSite Impact Response System administrator during setup of player profiles (see Player Setup, p. 33). Each InSite Player Unit is comprised of a flexible sensor array (Sensor) and a small wireless radio transceiver (Transmitter). P/N XXXXX vX.XX Page | 6 Power is provided by a non-rechargeable battery through an advanced power management system that automatically puts the unit into sleep mode when it is motionless, and into active operation once it detects motion. This functionality enables a typical battery life of approximately one year depending on usage. The Player Units battery must be replaced once each year during reconditioning by a Riddell factory-authorized reconditioning center. Please call Riddell Customer Service at (800) 275-5338 for the factory-

authorized reconditioning center nearest you. Failure to replace the battery each year will result in loss of power and the Player Unit will become inoperable. RIDDELL SIDELINE MONITOR The Riddell Sideline Monitor (RSM) is a cell phone with an Android application which allows a user to collect impact event data from one or more Player Units (PUs) as well as perform management functions on individual PUs. The officially supported phone for running RSM is the Samsung Galaxy S10. USB CABLE AND AC CHARGER P/N XXXXX vX.XX Page | 7 The USB cable connects the Riddell Sideline Monitor to a laptop or desktop, which functions to charge the Sideline Monitor batteries. An AC Charger is also included, that plugs into any 110V AC wall outlet. When used together with the USB cable, the AC Charger supplies electricity to recharge the Sideline Monitor batteries. P/N XXXXX vX.XX Page | 8 EQUIPMENT GUIDE AXIOM PLAYER UNIT BATTERY CARE InSite Player Units are powered by a factory installed non-rechargeable battery. The Player Units battery must be replaced once each year during reconditioning by a Riddell factory-authorized reconditioning center. Please call Riddell Customer Service at (800) 275-5338 for the factory-authorized reconditioning center nearest you. Failure to replace the battery each year will result in loss of power and the Player Unit will become inoperable. CONTROLS AND INDICATORS The Player Unit transmitter is located in a protective pouch in each InSite Axiom fixed liner. It is used to transmit impact data to the Riddell Sideline Monitor, and is connected to the sensor pads. The Player Unit has two basic states while powered On idle and sleep. The Player Unit will manage its own power state to maximize battery life based on recent activity detected by a motion sensor. 1) LED A powered and functional player unit will rapidly flash a yellow LED when put in motion after 5 seconds of stationary inactivity. 2) Power button - The button on the player unit is used to power the unit on from shipping mode, and only needs to be accessed during initial setup and after reconditioning. P/N XXXXX vX.XX Page | 9 3) Identification Number (Serial Number) 10-digit number that identifies a particular Player Unit. This number will appear in the Riddell Sideline Monitor application when the Player Unit is added. This number is used to assign individual Player Unit hardware to a Player. TBD TBD INSTALLATION INTO HELMETS Proper installation and setup of the InSite Impact Response System is required for correct product operation. Please keep in mind the following key points and instructions as you prepare for use:

InSite Player Units and Overliners are designed to fit specific Riddell helmet models and sizes (see www.Riddell.com). To ensure player safety and proper impact measurement performance, use InSite only with compatible helmet types. InSite Alert thresholds are assigned based on Playing Position and Skill Level. For correct operation of InSite, Playing Position and Skill Level must be properly assigned to each player when configuring InSite (see Player Setup, p.34).

P/N XXXXX vX.XX Page | 40 USING INSITE BEFORE PLAY TBD DURING PLAY - USING ALERTS During a game, Player Units monitor and record significant impacts, and will transmit Alerts to the RSM when impact exposure thresholds are exceeded. If an Alert is generated while the Player Unit is out of communication range (50 yards), the Alert will be stored on the Player Unit until it is successfully transmitted to the RSM. Player name, jersey number, date of impact, time of impact, and alert type (single or multiple) will be displayed on the Sideline Monitor when the Alert is received. The Alert will remain active on the Sideline Monitor until it is acknowledged. HIT SEVERITY PROFILE (HITSP) InSite Player Units monitor impact exposure using a novel impact exposure metric called HITsp (HIT Severity Profile). HITsp combines effects of the following into a single numerical index:

Linear and rotational acceleration, Impact location, and Impact duration Since 2004, Riddell has collected millions of impacts on-field at all levels of play using the Sideline Response System. Based on data collected during this novel research, HITsp and InSite Alert thresholds were developed. While InSite does not diagnose concussions or other head injuries and is not intended to be used as a diagnostic device, P/N XXXXX vX.XX Page | 41 HITsp does provide for a more specific correlation of on-field injuries and impact exposure than single factors alone1. ALERT TYPES InSite provides two types of impact Alerts, Single Impact and Multiple Impact. Both Alert types indicate that atypically high head-impact exposure has been experienced by the player, and that clinical best practices should be used to conduct an assessment for potential head injury (concussion). Alert thresholds are customized based on level of play and playing position on the field. Alerts report atypically high exposure relative to other players of similar level of play at the same playing position. Single Impact Alerts - Alerts impacts whose severities are above the predetermined threshold for the player position and play level as assigned using InSite Player Management software. Single event Alerts exceed the 99th percentile HITsp value for that skill level and playing position (i.e. the top 1%) based on field data collected using the Riddell Sideline Response System. Multiple Impact Alerts - are a proprietary cumulative exposure Alert created by a combination of:

1) Cumulative Impact Exposure Score all impacts exceeding the 95th percentile (i.e. top 5%) are added to a time-

weighted rolling 7-day index. 2) Magnitude of the most recent incoming impact. When the sum of the cumulative index and the most recent incoming impact exceeds a pre-determined cumulative exposure threshold, a Multiple Impact Alert is generated. If a Player has a high cumulative score, relatively small single 1Greenwald RM, Gwin JT, Chu JJ, Crisco JJ., Head impact severity measures for evaluating mild traumatic brain injury risk exposure, Neurosurgery, 2008 Apr, 62(4):789-98, discussion 798. P/N XXXXX vX.XX Page | 42 impacts may result in over-exposure and generation of a Multiple Impact Alert. VIEWING NEW ALERTS TBD ALERT RESPONSE Alerts (either single or multiple) are indicative of higher-than-normal impact exposure. When an Alert is received, you should deploy your programs concussion and head injury assessment protocol immediately. For more information, see CDC concussion guidelines:

http://www.cdc.gov/concussion/

AFTER PLAY EQUIPMENT MANAGEMENT The following steps should be followed after every practice or game:

1) Player Units Leave Player Units in helmets and leave them powered on. The Player Units will enter a sleep state when left motionless for several minutes. 2) Sideline Monitor View information on the Riddell Sideline Monitor and charge as needed. 3) Software Review Alerts using ITT Software. Make any equipment/team configuration changes for the next game or practice, and Sync the Sideline Monitors for all affected teams. P/N XXXXX vX.XX Page | 43 MAINTENANCE To keep your equipment in peak operating condition, perform these maintenance procedures at periodic intervals.
