Re:  Assignment of Promissory Notes

Dear Sirs:

This letter will serve to set forth and confirm our agreement whereby, as of
even date herewith, NetStaff, Inc. ("NetStaff') assigns to Golden Horde
Investments Ltd. ("Golden Horde"), and Golden Horde hereby accepts such
assignment and agrees to assume the obligations of NetStaff with respect to, the
following Promissory Notes, a copy of which are attached hereto for reference:

1. Promissory note, dated July 26, 1999, issued to Lori Hoffer for the sum of
$25,000, plus twelve percent interest per annum, due April 25, 2000;

2. Promissory note, dated July 26, 1999, issued to Wayne Sanders and Bette
Sanders, jointly, for the sum of $50,000, plus twelve percent interest per
annum, due April 25, 2000; and

3. Promissory note, dated June 16, 1999, issued to Sherrin Lim for the sum of
$25,000, plus twelve percent interest per annum, due on March 21, 2000.

In consideration of your accepting this assignment and assuming the repayment
obligations of NetStaff under the aforesaid Promissory Notes, NetStaff agrees
that after its merger and reorganization with a public reporting company, MAS
Acquisition VIII Corp., an Indiana corporation, NetStaff will use its best
efforts to ensure that the Board of the newly reorganized company, issues to
you, or at your direction, warrants to purchase up to an aggregate of two
hundred thousand (200,000) shares of common stock of the newly reorganized
company at a price of US$1.00 per share. Such common stock when issued shall be
duly and fully issued, fully-paid and nonassessable shares.

<PAGE>   2

The warrants will be exercisable at any time between sixty (60) days from the
date the shares of reorganized company are quoted for trading on the OTC
Bulletin Board and the third anniversary of such date (the "Applicable Term").
The aggregate amount of two hundred thousand (200,000) warrants may be
exercisable in whole, in part or in increments at any time during the Applicable
Term.

The shares underlying the warrants shall be entitled to "piggyback" registration
rights in the event that the newly reorganized company files or proposes to file
a registration statement under the US Securities Act of 1933, as amended (other
than a registration statement relating to an SEC Rule 145, or a successor rule,
or a registration on any form which does not permit secondary sales) at any time
during the Applicable Term; provided, however, that in the case of an
underwritten public offering, participation by the holder(s) of the warrants
shall be ratably limited to such number of shares determined by the managing
underwriter as is feasible for sale in such underwritten offering after taking
into account all securities that are to be sold on behalf of the company.

Accepting that the above accurately details our agreement, please execute this
letter agreement where indicated and fax back to me a fully executed copy.

Yours truly, NETSTAFF, INC.

        (iv)        a further 200,000 options as of the date the Company

such triggering events.

or merger is closed without the direct assistance of Contractor, then such
transaction shall not be counted as a "triggering event" such as set forth
above.

Upon termination of the Agreement, any ungranted Options shall terminate.
