               BY AND AMONG CAMBEX CORPORATION, SUPER PC MEMORY, INC.,
                   SON T. PHAM, SIMON LE AND RICHARD G. SCHAEFER


	This Amendment, dated as of the 29th day of July, 2002 (the
"Amendment"), is made to the Stock Purchase and Sale Agreement, dated as of
January 31, 2002 (the "Agreement"), by and among Cambex Corporation, a
Massachusetts corporation (the "Buyer"), Super PC Memory, Inc., a California
corporation (the "Company"), Son T. Pham, Simon Le and Richard G. Schaefer,
(each individually a "Seller" and collectively, the "Sellers").

	WHEREAS the parties to this Amendment entered into the Agreement as of
January 31, 2002 and closed on the transactions contemplated in the Agreement
as of March 12, 2002;

	WHEREAS the parties to the Agreement desire to amend certain provisions
thereof and to memorialize such changes in this Amendment; and

	WHEREAS Section 10.03 of the Agreement provides that the Agreement may
be amended by written agreement executed by all of the parties to the
Agreement.

	NOW, THEREFORE, in consideration of these premises, and for other good
and valuable consideration the receipt and sufficiency of which is hereby
acknowledged, the parties hereto agree as follows:
1.	To amend the Agreement as follows:

(a) SECTION 1.02 Purchase Price.

Section 1.02 is deleted in its entirety and replaced with the following:

		SECTION 1.02  Purchase Price.  The total consideration to be
delivered to the Sellers, collectively, in exchange for the Shares (the
"Purchase Price") is 840,000 shares of unregistered common stock, par value
$0.01 per share (the "Common Stock") of the Buyer (the "Cambex Shares").  The
Purchase Price will be paid to the Sellers, with each Seller being provided
with his pro rata share of the Purchase Price based on his ownership interest
in the Company.

(b) SECTION 1.03 Purchase Price Adjustments.

Section 1.03 is deleted in its entirety and replaced with the following:

SECTION 1.03  Net Assets on the Closing Date.  Within 60 days of Closing,
Sellers shall deliver to Buyer an audited balance sheet of the Company as of
the Closing Date prepared by Weinberg & Co., S.E.C. qualified accountants
(the "Closing Date Balance Sheet"), prepared in accordance with generally

<PAGE>
accepted accounting principles, prepared on a basis consistent with the
preparation of the Balance Sheet (as defined in Section 2.08 hereof).  The
Purchase Price to be paid by Buyer to Sellers for the Shares is premised upon
the Company having total assets minus liabilities ("Net Assets") as of the
Closing Date of at least Two Million One Hundred Thousand Dollars
($2,100,000.00) (the "Minimum Net Asset Amount") as set forth on the
Company's Closing Date Balance Sheet.  For purposes of this determination,
Net Assets shall be the sum of all current assets plus other assets all as
set forth in the Closing Date Balance Sheet, reduced by the amount of all
current liabilities and long term liabilities as set forth in the Closing
Date Balance Sheet.  In the event that the Company does not have Net Assets
on the Closing Date of at least the Minimum Net Asset Amount, then Buyer
shall have the right to reduce the monies, including accrued interest, owing
to the officers of the Company pursuant to the "Loan to Officers" referred to
on the Closing Date Balance Sheet (the "Officers' Loan") by the difference
between the Minimum Net Asset Amount and the Net Assets (such difference, the
"Net Asset Shortfall").  Son T. Pham, who is the sole creditor under the
Officers' Loan, hereby agrees to any such reduction in the principal payments
and any accrued interest owing to him in connection with the Officers' Loan
in accordance with the terms of this Section 1.03.  If the Net Asset
Shortfall exceeds the amount of the Officers' Loan, plus accrued interest on
the Officers' Loan, then the Officers' Loan and any accrued interest on the
Officers' Loan will be offset in its entirety.  The terms of this Section
1.03 shall survive the Closing.

(c) SECTION 1.04 Closing.

Subsection 1.04(B)(iv) is deleted in its entirety.  The Security Agreement
attached as Exhibit 1.04B is deleted in its entirety.  The Pledge Agreements
attached as Exhibit 1.04C are deleted in their entirety.  The Escrow
Agreements attached as Exhibit 1.04D are deleted in their entirety.

(d) SECTION 2.08 Financial Statements.

The reference in lines 5 and 6 to "Section 1.03(b)" is deleted and replaced
with the words "Section 1.03".

(e) SECTION 5.12 No Merger.

Section 5.12 is deleted in its entirety.

(f) EXHIBIT 1.02 is deleted in its entirety.

2.	Except as otherwise expressly provided herein, the Agreement is hereby
ratified and confirmed and shall remain in full force and effect.

<PAGE>
3.	This Amendment may be executed in any number of counterparts, each such
counterpart shall be deemed to be an original instrument, and all such
counterparts together shall constitute but one agreement.

4.	Capitalized terms not otherwise defined herein shall have the meanings
ascribed to such terms in the Agreement.

5.	Except as specifically provided herein, nothing in this Amendment shall
be deemed a waiver of any of the rights or obligations of the parties under
the Agreement.
