## 2. EXCEPTION LIST
| Exception Type | Provision / Subject | Description | Source(s) | Impact on Reconciliation | Human Review Required |
| ---------------------------------------- | ------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------------------------------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------ |
| Apparent supersession | Lease term | The original March 31, 2026 expiration was expressly extended first to September 30, 2026 and then further to March 31, 2027. This is an observed document relationship, not a legal determination of supersession. | Document 1, Section 2.1; Document 2, Section 2; Document 3, Section 4 | Latest stated expiration is March 31, 2027. | No, for documentary reconciliation; legal review may be appropriate for any legal-control question. |
| Apparent supersession | Base Rent | The original annual rent/escalation framework is expressly supplemented for the post-original-term period by a stated monthly rent beginning April 1, 2026. The Second Amendment then expressly maintains that monthly amount through March 31, 2027. | Document 1, Section 3.1; Document 2, Section 3; Document 3, Section 5 | Latest stated rent for the amended period is $48,125 per month. | No, for documentary reconciliation; legal review may be appropriate regarding interaction with the unmodified portions of Exhibit B. |
| Insufficient evidence / scope limitation | Base Rent schedule | The supplied materials reference Exhibit B but do not provide its detailed rent schedule. The reconciliation therefore does not independently verify the original annual escalation amounts beyond the stated $555,000 Lease Year 1 amount and 2.5% annual increase. | Document 1, Section 3.1 and stated lease summary | Does not prevent reconciliation of the expressly amended rent period, but limits verification of the full historical rent schedule. | Yes, if a complete rent history or comparison to Exhibit B is required. |
| Evidence scope limitation | Document intake / source detail | The supplied materials identify all three documents, their dates, roles, and relevant provisions, but do not provide page numbers or other more granular locators. No such locators were invented. | Documents 1–3 | Source traceability is maintained at the document/section level only. | No, unless more granular citation is required. |
## 3. FINAL RECONCILIATION NOTE
**SUPPORTED RECONCILIATION**

Documents 2 and 3 are **AMENDMENTS** dated September 30, 2022 and February 14, 2024, respectively, and their dated sequence supports the reconciliation order.
The latest stated position in the supplied materials is that the lease term runs through **March 31, 2027**, and Base Rent is **$48,125 per month from April 1, 2026 through March 31, 2027**.

The supplied materials are sufficient for the requested reconciliation, subject to the limitation that the detailed Exhibit B rent schedule was not provided.
