                                  KEY EMPLOYEE
                              SALE BONUS AGREEMENT

      THIS SALE BONUS AGREEMENT (this "Agreement"), is made and entered into as
of December __, 2004, between DEI HOLDINGS, INC. (the "Company") and
_____________________ (the "Key Employee").

                                    Recitals

      A.    The parties are entering into this Agreement for the purpose of
providing the Key Employee an incentive to increase the value of the Company by
granting him the right to receive a percentage of the proceeds received by the
Company's shareholders as a result of certain liquidity events.

      B.    The parties' intent is that upon specified liquidity events, the
Company pay to the Key Employee a percentage of the proceeds distributable to
common holders (not warrant holders) as follows:

            (i)   the Key Employee shall not receive any percentage of the net
                  proceeds necessary to "repay" a "base equity amount" equal to
                  the sum of (x) $89,750,000 (i.e., the sum of the agreed upon
                  equity value of the Company following its June 2004
                  recapitalization plus the $6.0 million of equity contributed
                  to the Company in September 2004), plus (y) any additional
                  equity contributed after the date hereof, together with a 12%
                  annual "preferred return" on such additional equity; and

            (ii)  the Key Employee shall receive __% of all net proceeds
                  distributable to common holders in excess of such base equity
                  amount.

      C.    Attached as Annex A are certain examples showing the payment due the
Key Employee under various sale scenarios.

                                    Agreement

            (b)   The Sale Bonus shall be satisfied in the same form of
consideration as is received by the Trivest Investors. If the Trivest Investors
receive a combination of cash and property, the Sale Bonus shall be satisfied in
such forms in the same proportion as is received by the Trivest Investors.

            (c)   If all or a portion of the consideration payable by reason of
a Sale Event is payable over time or based upon the existence or occurrence of
events in the future, the amount of the Sale Bonus shall be computed based on
the actual consideration received by the Company's equity holders at closing and
the Sale Bonus shall include the right to receive the percentage of the Proceeds
Available for Distribution to Shareholders applied to such future consideration
as and when such consideration is received.

      5.    Modification to Right. In the event of an extraordinary corporate
transaction, including, by way of example, any material acquisition or
disposition of assets or securities other than in the ordinary course of
business, or any material financing transaction, the Board shall in good faith
review for reasonableness the Sale Bonus formula specified in Section 2 hereof
and shall take such action, if any, as the Board in good faith deems necessary
to adjust such formula in light of the circumstances existing at such time.

      6.    Term. The Company's obligation to pay the Sale Bonus (or portion
thereof) granted hereunder shall terminate upon the earlier to occur of: (a) the
Key Employee's termination for Cause, death or permanent disability, (b) the Key
Employee's voluntary resignation, (c) three (3) months after the Key Employee's
termination without Cause, or (d) seven years from the date hereof.

      7.    Non-Transferability. Key Employee's rights under this Agreement may
not be sold, pledged, assigned, hypothecated, gifted, transferred or disposed of
in any manner either voluntarily or involuntarily by operation of law.

      8.    Withholding. The Company reserves the right to withhold, in
accordance with any applicable laws, from any consideration payable or property
transferable to the Key Employee, any taxes required to be withheld by federal,
state or local law as a result of the entering into this Agreement or the
receipt of cash or property upon a Sale Event. If the amount of any
consideration payable to the Key Employee is insufficient to pay such taxes or
if no consideration is payable to the Key Employee, upon the request of the
Company, the Key Employee shall pay to the Company an amount sufficient for the
Company to satisfy any federal, state or local tax withholding requirements it
may incur, as a result of the entering into of this Agreement or the receipt of
cash or property upon a Sale Event.

      9.    Employment. This Agreement shall not confer upon the Key Employee
any right to continue in the service of the Company or any subsidiary or limit,
in any respect, the right of the Company or any subsidiary to discharge the Key
Employee at any time, with or without Cause and with or without notice.

      10.   Governing Law. This Agreement shall be construed in accordance with
the laws of the State of California, without regard to the application of the
principles of conflicts of laws.

      11.   Amendment. This Agreement may only be amended by a writing signed by
each of the parties hereto.
