This constitution was later accepted by the US Congress, making Texas a US state on the same day annexation took effect, December 29, 1845 (therefore bypassing a territorial phase). One of the motivations for annexation was the huge debts which the Republic of Texas government had incurred. As part of the Compromise of 1850, in return for $10,000,000 in Federal bonds, Texas dropped claims to territory that included parts of present-day Colorado, Kansas, Oklahoma, New Mexico, and Wyoming. The resolution did include two unique provisions: First, it said up to four additional states could be created from Texas' territory with the consent of the State of Texas (and that new states north of the Missouri Compromise Line would be free states). Though the resolution did not make exceptions to the constitution, the U.S. Constitution does not require Congressional consent to the creation of new states to be "ex post" to applications, nor does the U.S. Constitution require applications to expire. To illustrate the strength of the latter caveat, the 27th Amendment was submitted to the states in 1789, yet was not ratified until 1992—thus, the expressed consent of Congress, via this resolution, to the creation of new states would not expire nor require renewal. Second, Texas did not have to surrender its public lands to the federal government. While Texas did cede all territory outside of its current area to the federal government in 1850, it did not cede any public lands within its current boundaries. Consequently, the lands in Texas that the federal government owns are those it subsequently purchased. This also means the state government controls oil reserves, which it later used to fund the state's public university system through the Permanent University Fund. In addition, the state's control over offshore oil reserves in Texas runs out to 3 nautical leagues (9 nautical miles, 10.357 statute miles, 16.668 km) rather than three nautical miles (3.45 statute miles, 5.56 km) as with other states.
