Karyopharm 6th Amendment

Modified Gross

Newton, MA

This lease is a sixth amendment to an existing agreement, meaning the document contains no standalone lease terms - only changes to prior provisions. Extracting base rent requires reconciling escalation steps across multiple document layers. The amendment-only format confuses tools that expect a full lease document.

52,000 RSF$2.3M/yr

Bicara Therapeutics Expansion

Modified Gross

Boston, MA

This expansion amendment doubles the tenant's footprint from 4,600 to 9,300 RSF. Extracting the correct square footage requires distinguishing between the original premises, the expansion space, and the combined total. Rent is stated per-square-foot for the expansion space only, requiring calculation of the blended total rent.

9,300 RSF$558K/yr

Extend Health Amendment Chain

Modified Gross

Salt Lake City, UT

This file contains three consecutive amendments plus a landlord assignment document. Extracting the current lease terms requires reconciling changes across four documents, with each amendment superseding portions of the prior agreement. The landlord was also assigned (from original owner to Kilroy Realty), requiring verification that all lease obligations transferred correctly.

28,000 RSF$756K/yr

ATX Technologies Single-Tenant NNN

NNN

Boca Raton, FL

Single-tenant NNN office leases are common in net lease REIT portfolios but require careful extraction of the full NNN expense obligation alongside standard office lease terms. At 58,000 RSF on a 10-year term, this lease represents significant credit tenant exposure and includes a corporate guarantee structure typical of Vereit portfolio leases.

58,000 RSF$1.9M/yr

Infoblox Silicon Valley Sublease

Modified Gross

Santa Clara, CA

Sublease abstractions require extracting two sets of obligations: the sublease terms between sublandlord and subtenant, and the master lease terms that continue to bind the sublandlord. The subtenant's rights are limited by both the sublease and the master lease, and the consent requirements of the master landlord must be tracked.

35,000 RSF$1.4M/yr

ZixCorp Ontario Canada Sublease

Gross

Toronto, ON, Canada

This non-US lease is governed by Ontario, Canada law and references Canadian dollar amounts, provincial tax provisions, and Canadian landlord-tenant regulations that differ substantially from US commercial lease norms. Cross-border extraction must correctly handle currency, legal references, and province-specific provisions.

18,000 RSF$576K/yr

Warehouse, manufacturing, and cultivation facility NNN leases

Corsair Industrial NNN

NNN

Milpitas, CA

This NNN lease includes a 3-month rent abatement at lease commencement and a pro rata share calculation based on a multi-tenant industrial park. The abatement period and pro rata methodology must be extracted accurately for rent roll verification and cash flow modeling.

40,000 RSF$960K/yr

Northann Warehouse

NNN

Fontana, CA

At 106,000 RSF, this is the largest warehouse in the extraction corpus by area. The lease contains multiple rent escalation schedules tied to CPI with a fixed floor and ceiling, and a complex early termination right exercisable in year 4 with a substantial termination fee formula.

106,000 RSF$1.7M/yr

Sutro Biopharma Industrial

NNN

South San Francisco, CA

Sutro Biopharma occupies what is classified as industrial space but operates a biologics manufacturing facility, making this a hybrid industrial/life sciences lease. The escalating rent schedule runs through 7 years with annual 3% bumps. The use clause requires specialized hazardous materials handling provisions that interact with the NNN expense structure.

47,000 RSF$2.5M/yr

Broken Arrow Marijuana Grow Facility

NNN

Broken Arrow, OK

Large-scale marijuana cultivation facilities occupy industrial buildings but require specialized infrastructure (grow lighting, HVAC, water systems) that creates unusual TI provisions and utility cost structures. Oklahoma's medical marijuana program creates state-specific licensing provisions that differ from Colorado and California cannabis leases.

Frequently Asked Questions

What types of case studies does Lextract publish?
Lextract publishes case studies that show real lease extractions across major property types. These cover office, industrial, life sciences, retail, and specialty structures like REIT master leases and datacenter power leases. Each case study documents the lease structure, the extraction challenges, and the 126 structured fields Lextract produced.
How much time does Lextract save on lease abstraction?
Lextract typically processes a commercial lease PDF in 5 to 15 minutes. Manual abstraction usually takes 4 to 8 hours. Lextract costs $15 per lease. Outsourced or manual abstraction services commonly run $90 to $250 per lease.
Are these case studies from real customers?
No. These case studies show how the extraction pipeline handles different lease document types and complexity. They are not customer stories. Named tenants and landlords come from publicly available lease documents, often lease exhibits attached to public SEC filings, or are illustrative names used to frame a scenario. Their inclusion is not a claim that they are Lextract customers or that they endorse the product. The extraction outputs shown, such as fields, values, confidence scores, and red flags, are the actual results Lextract produced on the underlying document.
Can I submit my own case study?
If you have used Lextract on a complex lease and want to share the results, contact us. We feature interesting extractions such as unusual lease structures, multi-amendment chains, or industry-specific provisions that show what the 126-field schema can do.
