VENDOR COMPLIANCE TO STATE LAW
The 1985 Session of the Texas Legislature passed House Bill 620 relative to the award of contracts to non-
resident bidders. This law provides that,in order to be awarded a contract as low bidder,non-resident bidders
(out-of-State contractors whose corporate office or principal place of business are outside of the state of
Texas)bid projects for construction,improvements,supplies or services in Texas at an amount lower than the
lowest Texas resident bidder by the same amount that a Texas resident bidder would be required to underbid
a non-resident bidder in order to obtain a comparable contract in the state in which the non-resident's principal
place of business is located. The appropriate blanks in Section A must be filled out by all out-of-state or non-
resident bidders in order for your bid to meet specifications. The failure of out-of-state or non-resident
contracts to do so will automatically disqualify that bidder. Resident bidders must check the blank in Section
B.
A. Non-resident vendors in (give state), our principal place of business, are required to be
percent lower than resident bidders by state law. A copy of the statute is attached.
Non-resident vendors in (give state),our principal place of business,are not required to
underbid resident bidders.
B. Our principal place of business or corporate offices are in the State of Texas:

VENDOR COMPLIANCE TO STATE LAW
.6 The 1985 Session of the Texas Legislature passed House Bill 620 relative to the award of contracts to non-
resident bidders. This law provides that,in order to be awarded a contract as low bidder, non-resident bidders
(out-of-State contractors whose corporate office or principal place of business are outside of the state of Texas)
bid projects for construction,improvements,supplies or services in Texas at an amount lower than the lowest
Texas resident bidder by the same amount that a Texas resident bidder would be required to underbid a non-
resident bidder in order to obtain a comparable contract in the state in which the non-resident's principal place
of business is located. The appropriate blanks in Section A must be filled out by all out-of-state or non-resident
bidders in order for your bid to meet specifications. The failure of out-of-state or non-resident contracts to do so
will automatically disqualify that bidder. Resident bidders must check the blank in Section B.
A. Non-resident vendors in (give state), our principal place of business, are required to be
percent lower than resident bidders by state law. A copy of the statute is attached.
Non-resident vendors in Georgia (give state), our principal place of business, are not
required to underbid resident bidders.
B. Our principal place of business or corporate offices are in the State of Texas:
