# SIGNAL PILOT LETTER OF INTENT

**Date:** June __, 2026
**Between:**
- **STTIL Solutions LLC** ("Provider"), a limited liability company, Kisa Fenn, Managing Member
- **Gaboro DME** ("Partner"), Robert Robinson, Co-Founder and Managing Partner

---

## 1. Purpose

This Letter of Intent ("LOI") sets forth the agreed terms for a 90-day pilot engagement of Signal, a documentation readiness tool developed and operated by STTIL Solutions LLC ("Signal"). This LOI is not a binding contract but reflects the shared intent of both parties to proceed on the terms described herein. A formal Pilot Agreement will be executed prior to the first data upload.

---

## 2. Scope of Pilot

During the pilot period, Partner will upload de-identified order management CSV exports to Signal. Signal will process the CSV data to produce a prioritized documentation worklist showing per-patient status across qualifying visit dates, standing written orders, prior authorization, PECOS enrollment, and supply cycle status. Partner staff will act on the worklist output. Signal identifies documentation conditions; Partner staff conduct all outreach and supply decisions.

Signal does not contact patients or prescribers directly at any time.

---

## 3. Pilot Duration

The pilot period is **90 days** from the date of the first successful CSV upload by Partner ("Pilot Start Date"). The pilot may be extended by written mutual agreement.

---

## 4. Pilot Fee

The pilot period is provided at **no charge**. At Partner's election to continue as a paying subscriber following the pilot, the monthly fee is **$199 per month** for the Signal Worklist tier. This rate is locked for the life of Partner's subscription as a founding pilot partner and will not be subject to standard price increases so long as the subscription remains active.

---

## 5. Data Handling

**De-identified data only.** Partner will upload CSV files containing: an internal patient identifier (the supplier's own MRN or account number), device type, shipment date, and payer name. Partner will not include patient names, Social Security numbers, dates of birth, addresses, or any other direct identifiers in uploaded files.

STTIL Solutions will not store patient names, SSNs, DOBs, addresses, or contact information at any time. The patient identity crosswalk (internal patient_id to real patient identity) remains solely with Partner's staff.

STTIL Solutions will store: hashed patient identifiers, device type, shipment date, payer name, calculated documentation status, and staff-confirmed visit dates (entered by Partner staff via the Signal interface).

Both parties acknowledge that Partner is responsible for ensuring that the data uploaded complies with applicable HIPAA de-identification requirements and Partner's own compliance obligations.

---

## 6. Feedback and Case Study Rights

Partner agrees to provide good-faith feedback on Signal during the pilot period, including but not limited to: functionality, accuracy of documentation status calculations, worklist usability, and feature gaps.

STTIL Solutions may use anonymized, aggregated data from the pilot (with no identifying information about Partner's patients, staff, or business operations) for product improvement and investor reporting.

STTIL Solutions may prepare a case study describing the pilot outcomes. Any case study that identifies Partner by name requires Partner's prior written approval before publication.

---

## 7. Reference Rights

Partner grants STTIL Solutions the right to identify Partner as "an engaged pilot partner of Signal" in investor materials, marketing materials, and conversations with prospective partners and investors. STTIL Solutions will seek Partner's written approval for any specific usage of Partner's name or logo beyond this general reference right. This reference right may be revoked by Partner with 30 days written notice to STTIL Solutions.

---

## 8. Termination

Either party may terminate the pilot engagement with **30 days written notice** delivered by email to the other party's designated contact. Upon termination or conclusion of the pilot:
- STTIL Solutions will delete all Partner data from Signal systems within **10 business days** of the effective termination date.
- STTIL Solutions will provide written confirmation of data deletion upon Partner's request.

---

## 9. Intellectual Property

Signal, including its algorithms, software, and documentation readiness methodology, is and remains the sole intellectual property of STTIL Solutions LLC. Nothing in this LOI grants Partner any license to Signal's underlying technology beyond the right to use Signal as a software service during the pilot period.

Partner retains all rights to its operational data, patient records, and business information shared during the pilot.

---

## 10. Confidentiality

The parties agree to keep the terms of this LOI and all information shared during the pilot confidential. A mutual Non-Disclosure Agreement ("NDA") will be executed concurrently with this LOI and governs the confidentiality obligations of both parties in detail.

---

## 11. No Binding Commitment

This LOI is not a binding legal agreement and does not obligate either party to proceed with a commercial relationship. A formal Pilot Agreement reflecting the terms of this LOI will be prepared for signature prior to the Pilot Start Date.

---

## 12. Governing Law

This LOI and any formal agreements arising from it shall be governed by the laws of the **Commonwealth of Pennsylvania**, without regard to its conflict of law principles.
