  Re:      Terms of Employment

Effective as of this date, the terms of your employment with the Company are
modified as follows:

..    Service Bonus, If you remain employed by the Company through October 3
     1, 2001, you will be entitled to receive a lump sum bonus in the amount of
     $50,000 (subject to applicable payroll taxes and withholding). If you
     remain employed through November 30, 2001, you will receive an identical
     lump sum bonus.

..    If you remain employed by the Company through November 30, 2001, then you
     will also receive the following:

     1.  DCI Options. The unvested portion of the three tranches of options
         originally issued to you on or about July 23, 1998 through Dynamic
         Circuits, Inc. having strike prices of $0.0013, $21.79, and $0.0296,
         respectively, of which 1,217 options, 334 options and 1,586 options,
         respectively, are currently unvested, shall be vested in full. These
         options may be exercised at any time within 12 months after termination
         of employment;

     2.  DDi Options. The unvested options in DDi Corp. common stock issued to
         you pursuant to the DDi Corp. 2000 Equity Incentive Plan shall be
         vested on a pro-rata basis calculated by multiplying the number of
         unvested options in each tranche by a fraction, the numerator of which
         equals the number of days from the date of option grant through and
         including November 30, 2001, and the denominator of which equals 365
         days. These options may be exercised at any time within 12 months after
         termination of employment;

     3.  The vested DCI and DDi options currently held by you are hereby amended
         so that they may also be exercised any time within 12 months after
         termination of employment (see attached ASTSTOCKPLAN exercisable stock
         schedule);

     4.  The remaining unpaid Deferred Payments under 6.6 of your Employment
         Agreement shall vest and be paid in accordance with the schedule set
         forth therein, namely, the annual installment payment due under
         subparagraph (a)(ii) shall be made on August 19, 2002, and the
         quarterly installment payment due under subparagraph (b) shall be paid
         on December 31, 2001. The quarterly installment payment due under (a)
         (ii) on September 30, 200l shall be paid on that date;

     5.  The one-year non-compete period described in section 2.1 of that
         certain Non-Compete and Technology Transfer Agreement (the "Non-Compete
         Agreement) dated July 23, 1998 between Details Holdings Corp. (now
         known as DDi Corp.)

<PAGE>

        and you, shall be deemed to start on the date hereof. The Non-Compete
        Agreement shall otherwise remain unchanged;

     6. For the period commencing on December 1, 200l through the end of the
        non-compete period (i.e., the one year anniversary of the date hereof),
        you will receive the sum of $250,000 in equal monthly installments; and

     7. You will receive a sum equal to the fair market value of 10,000 shares
        of DDi common stock (based on the value of the shares at the high trade
        value based on the range in trading from September 18, 2001 through
        November 30, 2001).

..    Your duties from this date forward shall consist of effecting a transition
     of your current responsibilities to your successor. As soon as is
     reasonably practicable (by September 30, 2001), you will resign as a
     Board-elected officer, and the Company will remove your designation as
     Section 16 officer.

..    If the company terminates employment for any reason other than Cause (as
     defined in original employment agreement) prior to November 30, 2001, you
     shall be entitled to all payments, shares and vesting of options provided
     for herein as if you had remained in the employ of the Company through
     November 30, 2001.

These terms may not be altered except by a writing that has been signed by me.
Please indicate your acknowledgement and acceptance of the foregoing by placing
your signature in the block below and returning an executed copy of this letter
to me by facsimile.

Very truly yours,


/s/ Bruce D. McMaster

Bruce D. McMaster
