Attn: Mr. Barry Sloane

Gentlemen:

We refer to that certain Securities Purchase Agreement, by and among Technology
Investment Capital Corp., CrystalTech Web Hosting, Inc., and Newtek Business
Services, Inc., dated as of March 28, 2005 (the "Agreement"). All capitalized
terms used but not defined herein shall have the meanings ascribed thereto in
the Agreement.

The parties desire to amend Section 1.1 of the Agreement by amending and
restating the definition of "Special Prepayment Window" as follows:

"Special Prepayment Window" shall mean the period of time beginning on the first
day immediately after the first anniversary of the Closing Date and ending on
June 27, 2006."

The parties further desire to confirm their agreement that the Additional
Interest payable on March 31, 2006 in connection with the $4,000,000 optional
prepayment being made that same date (the “March 2006 Prepayment”), shall be
made in cash, in an amount equal to $127,033 (the “Additional Interest
Payment”), in lieu of Newtek delivering Newtek Shares pursuant to Section
2.5(d)(iv) of the Agreement. The Purchaser’s agreement to accept cash in lieu of
Newtek Shares does not alter the Purchaser’s right to receive Newtek Shares with
respect to any further Additional Interest payable under the Agreement.

After giving effect to and upon indefeasible receipt of the March 2006
Prepayment and the Additional Interest Payment: (x) the scheduled principal
payments specified under Section 2.6(a) of the Agreement shall be revised so
that the remaining principal payments due shall be as follows, (a) $2,000,000 on
March 28, 2008, and (b) the then remaining balance of the Notes on March 28,
2009; and (y) Section 2.4 of the Agreement shall be amended and restated in its
entirety as follows:

“Maturity Date. The entire unpaid principal amount of the Notes and any accrued
and unpaid interest thereon shall be due and payable on March 28, 2009 (the
“Maturity Date”), unless such amounts become due and payable earlier upon
acceleration in accordance with the terms hereof or otherwise.”
 
This letter is an amendment of the Agreement under Section 11.4 of the
Agreement. The Agreement remains in full force and effect, except to the extent
expressly modified herein. This letter shall be
