REDACTED FOR PUBLIC INSPECTION July 23, 2015 Federal Communications Commission 445 12"" Street, SW Washington, DC 20554 Re: Request for Confidential Treatment MC10, Inc. ("MC10") submits this application for Special Temporary Authority (the "Application") addressing those matters which the Application is required to address under 47 CFR5.61. By separate letter, MC10 requests confidential treatment of certain portions of Exhibit A to the Application. Pursuant to 47 CFR 5.53 and 5.54, the "public redacted" version of Exhibit A to MC10‘s Application is set forth in Exhibit C to the Application.

REDACTED FOR PUBLIC INSPECTION Exhibit C to MC10 Special Temporary Authority Application Detailed explanation of why the STA is needed. The Special Temporary Authority (STA) is required for conducting an experimental study with the Massachusetts General Hospital (MGH) using Proof of Concept devices designed and manufactured by MC10, Inc. The purpose of this study is to further the development of a novel experimental medical device that can assess — for patients with a certain set of BR1 particular, these devices will be useful for characterizing and quantifying sleep data from patients with ofi The Jjcarnings from this experiment will help drive improvements to both device hardware and software architectures, facilitating the pathway for the device to be released to market. Per its Institution Review Board (IRB) application process, MGH has requested that MC10 obtain an STA from the FCC for wireless devices used in experimental studies. While the MC10 device uses a Commercial Off—the—Shelf (COTS) System—on—Chip (SoC) radio solution, the transceiver system with integrated antenna is custom designed and does not currently have an associated FCC ID. To facilitate the execution of the study and further MC1O innovation and technology development, the STA represents the most effective means for completing the study in a reasonable time frame. Furthermore, the six month exemption the STA offers is an ample amount of time for MC1O to properly deploy, use, and evaluate the performance of the devices prior to retrieval from MGH. Detailed explanation on the type of operation that will be performed The study will involve patient volunteers who wear MC1O designed and manufactured Proof of Concept devices that use a Bluetooth® Low Energy (BLE) radio to transmit data to a receiver (e.g. PC laptop or smart device). These devices may be worn on the For the majority oftheir use, the devices will be advertising BLE packets with a low duty cycle (e.g. once every 10 seconds) to minimize radio transmission and power dissipation. No Personally Identifiable Information or Personal Health Information will be telemetered via the MC10 device. The volunteer will wear the device for MRafter which time the device will be returned to MC10 for data processing.

Description of the Geographical location and environment the operation will be performed. The device will be used inside an MGH facility within 1 km of the main campus: Massachusetts General Hospital 55 Fruit Street Boston, MA 02114 NAD 83 Latitude: 42.3631°N = 42° 21‘ 47.2"N Longitude: 71.0694°W = 71° 04‘ 9.8"W Description of any and all associated equipment used during operation. The device will primarily be used with a COTS PC laptop or smart device for transmitting data. Telemetry will be achieved using BLE v4.0 radios. In the case of the PC laptop, the Texas Instruments CC2540EMK—USB evaluation module, or similar, will be used. In the case of a smart device, an i0S device and its integrated BLE radio will be used. 8. Letter requesting confidentiality (if desired). Per CFR Title 47 0.457(d) and 0.459
