Amendment

Accordingly, EFT and B&V agree as follows:

1.The Agreement is hereby amended as follows:

(a)The first full independent clause before the colon in Section 2 of the Agreement is hereby amended to read as follows:

“ 2.#9;Each year, EFT will pay to B&V a dividend of 30% of the unencumbered royalties (prepaid or running) received by EFT from EFT’s licenses during the preceding calendar year, including any previously received royalties that became unencumbered during the preceding calendar year, subject to the following:”

(b)The first full independent clause before the colon in Section 2(c) of the Agreement is hereby amended to read as follows:

“ (c)#9;Any and all dividend payments (including any earned but unpaid dividend payments) from EFT to B&V hereunder will immediately cease (and, in the case of any earned but unpaid dividend payments, will no longer be due and payable) upon the earlier to occur of the following:”

(c)Section 2(d) of the Agreement is hereby amended to read as follows:

“ (d)#9;Any and all such dividend payments will be paid annually to B&V hereunder and will be due and payable on May 31^st of the following calendar year.”

(d)A new Section 2(g) is hereby added to the Agreement which reads as follows:

“ (g)#9;If EFT does not make all or any portion of any dividend payment due hereunder for any reason, including because such payment would be in violation of any law, rule or regulation applicable thereto, EFT’s COI or EFT’s Bylaws, then EFT shall track the obligation of such earned but unpaid dividend, and EFT shall pay any such earned and unpaid dividend as promptly as legally possible (but in no event later than 30 days after the date that such payment would not be in violation of any law, rule or regulation applicable thereto, EFT’s COI or EFT’s Bylaws, as reasonably determined in good faith by EFT’s board of directors). For any such earned but unpaid dividend, EFT hereby commits to B&V as follows: (i) EFT will use its reasonable efforts to continually assess on a regular basis whether or not the payment of such earned and unpaid dividend would still be in violation of any law, rule or regulation applicable thereto, EFT’s COI or EFT’s Bylaws, and (ii) if at any time EFT reasonably believes that such earned but unpaid dividend can legally be paid, EFT’s president will promptly call a board meeting so that the EFT board of directors can address such matter.”
