DOCUMENT 1

AMENDMENT NO. [AMENDMENT NUMBER] TO LEASE

[PREMISES SHORT DESCRIPTION — e.g., "Suite 201, 100 Main Street, Austin, Texas"]

This Amendment No. [AMENDMENT NUMBER] to Lease (the "Amendment") is made effective as of [AMENDMENT EFFECTIVE DATE] (the "Effective Date") between [LANDLORD NAME], [LANDLORD ENTITY TYPE AND STATE — e.g., "a Texas limited liability company" OR "an individual"] (the "Landlord"), and [TENANT NAME], [TENANT ENTITY TYPE AND STATE] (the "Tenant").

The Landlord and the Tenant are parties to a lease dated [ORIGINAL LEASE DATE] [, as amended on PRIOR AMENDMENT DATES, OR DELETE] (the "Lease") of the premises described in the Lease and known as [PREMISES DESCRIPTION] (the "Premises"). Capitalized terms not defined in this Amendment have the meanings given in the Lease. The parties agree to amend the Lease as follows.

Keep the amendments you need from the menu below and delete the rest. Each is complete on its own. The bracketed heading of each one tells you what it is for; delete that heading in the signed document and renumber the paragraphs you keep (1, 2, 3 ...).

[A — Extension of the term]

1. Extension of Term. The Term of the Lease is extended for [EXTENSION PERIOD — e.g., "three (3) years"], so that the Expiration Date is [NEW EXPIRATION DATE]. The extension is on the terms of the Lease as amended by this Amendment. [The renewal option in the Lease is exercised by this Amendment and no further renewal option remains, OR The renewal option in the Lease is unaffected and may be exercised for the period following the new Expiration Date, OR DELETE]

[B — Change of rent]

2. Rent. Beginning on [RENT CHANGE DATE], the Base Rent is $[NEW MONTHLY BASE RENT] per month [, increasing by NEW ANNUAL INCREASE PERCENTAGE% on each anniversary of that date, OR DELETE], payable as the Lease provides. [The Tenant's share of Operating Expenses is changed to NEW EXPENSE SHARE PERCENTAGE% beginning on the same date, OR DELETE] Rent for any partial month is prorated by the number of days.

[C — Rent deferral or abatement]

3. Rent Relief. The Base Rent for the months of [RELIEF PERIOD — e.g., "April through June 2026"] (the "Relief Period") is [abated in full OR reduced to $REDUCED RENT per month OR deferred]. [The deferred amount, $DEFERRED TOTAL, is repaid in NUMBER OF REPAYMENT MONTHS equal monthly installments of $INSTALLMENT AMOUNT, added to the Base Rent beginning on REPAYMENT START DATE, without interest, OR DELETE] If the Tenant defaults under the Lease beyond any cure period during the Relief Period or the repayment period, the relief ends and every abated or deferred amount becomes immediately due. All other rent and charges continue as the Lease provides.

[D — Expansion or reduction of the Premises]

4. Premises. Effective on [SPACE CHANGE DATE], the Premises [are expanded to include OR are reduced by] the space described as [SPACE ADDED OR REMOVED — e.g., "Suite 202, approximately 600 square feet"], so that the Premises thereafter consist of [NEW PREMISES DESCRIPTION AND APPROXIMATE AREA]. [The Landlord delivers the added space broom-clean, with its systems in working order, and the Tenant accepts it as is, OR The Tenant surrenders the removed space on that date in the condition the Lease requires at the end of the Term, OR DELETE] From that date the Base Rent is $[ADJUSTED MONTHLY BASE RENT] per month [and the Tenant's share of Operating Expenses is ADJUSTED EXPENSE SHARE PERCENTAGE%, OR DELETE], and every reference in the Lease to the Premises refers to the Premises as changed by this paragraph.

[E — Change of permitted use or trade name]

5. Permitted Use. The Permitted Use is changed to "[NEW PERMITTED USE]" and no other use. [The Tenant may operate at the Premises under the trade name "NEW TRADE NAME", OR DELETE] The Tenant obtains at its own cost every permit, license and certificate the new use requires, and the Landlord represents only that the Lease does not prohibit the new use.

[F — Change of the security deposit or guaranty]

6. Security Deposit and Guaranty. The Security Deposit is [increased to OR reduced to] $[NEW SECURITY DEPOSIT AMOUNT]. [The Tenant pays the difference of $DEPOSIT DIFFERENCE on signing this Amendment, OR The Landlord returns the excess of $DEPOSIT DIFFERENCE within thirty (30) days after the Effective Date, OR DELETE] [GUARANTOR NAME confirms below that the guaranty attached to the Lease continues in force and extends to the Lease as amended, OR The guaranty of FORMER GUARANTOR NAME attached to the Lease is released as of the Effective Date, OR DELETE]

[G — New landlord, new tenant name or new notice addresses]

7. Parties and Notices. [LANDLORD NAME has acquired the Premises from FORMER LANDLORD NAME and is the Landlord under the Lease; the Security Deposit has been transferred to it, OR The Tenant's name is changed to NEW TENANT NAME, the same legal entity, OR DELETE] Notices to the [Landlord OR Tenant] are sent to [NEW NOTICE ADDRESS AND EMAIL] from the Effective Date, and the notice provisions of the Lease are amended accordingly.

[H — Any other change]

8. Section [SECTION NUMBER TO CHANGE] of the Lease is [deleted OR amended by replacing it OR amended by adding at its end] with the following: "[NEW TEXT OF THE SECTION, OR DELETE]".

Provisions that apply to every amendment

9. Effect. Except as this Amendment provides, the Lease continues unchanged and in full force, and the Landlord and the Tenant ratify it. If the Lease and this Amendment conflict, this Amendment governs. The Tenant confirms that, as of the Effective Date, the Landlord is not in default under the Lease and the Tenant has no claim, offset or defense against the rent [, except: TENANT'S EXCEPTIONS, OR DELETE]. The Landlord confirms that the Tenant is not in default under the Lease [, except: LANDLORD'S EXCEPTIONS, OR DELETE].

10. General. This Amendment binds and benefits the parties and their successors and permitted assigns, is governed by the law that governs the Lease, and may be signed in counterparts and electronically, each of which is an original. [The Tenant will pay the Landlord's reasonable attorney's fees for this Amendment, not exceeding $AMENDMENT FEE CAP, OR DELETE]

INSTRUCTION SHEET

Commercial Lease Changes Kit

Lease amendment, sublease, assignment of lease and tenant estoppel certificate · Any U.S. State
Form US-RE-02 · Version 2026.3 · Last reviewed November 2026
READ THIS FIRST — This Instruction Sheet accompanies Form US-RE-02. It explains, in plain language, what each document in the kit does, how to complete each yellow field, and when the kit is not enough for your situation. It is general information, not legal advice. Keystone Legal Forms is not a law firm nor a legal services provider. Consult your own legal and tax advisors and other professionals about these documents before signing.
1. What this kit does and who it is for

A commercial lease rarely stays the same for its whole term. The tenant grows and needs the suite next door, or shrinks and wants to rent out two offices; the business is sold and the buyer needs the lease; the landlord sells the building and its lender wants the tenant's confirmation of the rent; a slow season calls for a few months of deferred rent. This kit contains the four documents those events require, written in plain language, for commercial premises in any U.S. state or the District of Columbia.

Document 1, the Amendment, changes the lease between the same landlord and tenant. Document 2, the Sublease, lets the tenant rent all or part of the space to someone else while staying on the lease; the landlord's consent is attached. Document 3, the Assignment, transfers the whole lease to a new tenant, with the landlord's consent and, if the landlord agrees, a release of the old tenant. Document 4, the Estoppel Certificate, is the tenant's written confirmation of the lease that a lender or buyer of the building asks for.

Use this kit if: the premises are commercial (office, retail, warehouse, workshop), the lease is in writing, and the change is one of those described above.

Use a different form if: the premises are a dwelling; the lease is a ground lease or a lease of a whole building to a single tenant with a purchase option; the sublease is to many subtenants (a coworking or executive-suite operation); or the landlord is a large shopping center or office tower owner that uses its own consent forms — then review its forms against these before signing.

2. How to complete the kit

• Work in Microsoft Word (or any program that opens .docx files). Every field appears in yellow highlight inside square brackets, for example [TENANT NAME]. Replace the whole bracket — including the brackets — with your information, and remove the highlight if you wish. Use Find and Replace for names that appear many times.

• Some fields offer choices, written as "OPTION A" OR "OPTION B", or begin with the word TYPE followed by the alternatives. Pick one, type that text in place of the entire bracket, and delete the alternatives. Never leave both options in the signed document.

• The amendment menu. Document 1 contains eight ready-made amendments, A through H, each introduced by a bracketed heading. Keep the ones you need, delete the rest, delete the bracketed heading of each one you keep, and renumber the paragraphs you keep in order (1, 2, 3 ...), keeping the two closing paragraphs at the end.

• Each document begins on its own page. Delete the documents you are not using, and delete the "Contents of this kit" page and the cover page before signing.
