You will also likely need a letter of authorization from the network
lending you their space for your upstreams or others.

Here's a usable template that you can customize for your own purposes.
Hope this helps:

Caveats, IPv6? Be sure to consult with lawyers, comply with your
favorite RIR policy and compare the cost of "renting" to "leasing" or
acquiring on the open market. There are a number of sources to acquire
IPv4 address space easily found using your favorite search engine.

You may be also be eligible for a last /22 allocation from RIPE if you
qualify under their current policy. See http://bit.ly/LASTCALL-22 for
further information.
