available for distribution in connection with future grants of Options and Stock
Purchase Rights under the Plan. Shares that have actually been issued under the
Plan shall not be returned to the Plan and shall not become available for future
distribution under the Plan except that if Shares are repurchased by the Company

                      ---------------------------
the Plan, and in the case of a Committee, subject to the specific duties

accordance with Section 2(l) of the Plan;

                 (ii) to select the Consultants and Employees to whom Options or
Stock Purchase Rights may be granted hereunder;

                 (v)  to approve forms of agreement for use under the Plan;

with the terms of the Plan, of any Option or Stock Purchase Right granted
hereunder. Such terms and conditions include, but are not limited to, the
exercise price, the time or times when Options and Stock Purchase Rights may be
exercised (which may be based on performance criteria), any vesting acceleration
or waiver of forfeiture restrictions, and any restriction or limitation
regarding any Option or Stock Purchase Right or the Shares relating thereto,
based in each case on such factors as the Administrator, in its sole discretion,
shall determine;

                 (vii)  to construe and interpret the terms of the Plan;

                 (viii)  to prescribe, amend and rescind rules and regulations
relating to the Plan;

                 (ix) to determine whether and under what circumstances an
Option or Stock Purchase Right may be settled in cash instead of Shares or
Shares instead of cash;

                 (x)  to modify or amend each Option or Stock Purchase Right

                 (xii)  to allow Optionees to satisfy withholding obligations by
electing to have the Company withhold from the Shares to be issued upon exercise
of an Option or Stock Purchase Right that number of Shares having a Fair Market
Value equal to the amount required to be withheld. The Fair Market Value of the
Shares to be withheld is to be determined by the Board. All elections by an
Optionee to have Shares withheld for this purpose shall be made in such form and
under such conditions as the Administrator may deem necessary or advisable;

                 (xiii)  to determine the terms and restrictions applicable to
Options and Stock Purchase Rights; and

                 (xiv)  to make all other determinations deemed necessary or
advisable for administering the Plan.


                 (c)  Effect of Administrator's Decision.  The Administrator's

                      -------
Options to eligible Consultants and Employees. Each Option shall be evidenced by
a Notice of Grant, which shall be in such form and contain such provisions as
the Administrator shall from time to time deem appropriate. Without limiting the
foregoing, the Administrator may at any time authorize the Company, with the
consent of the respective recipients, to issue new Options in exchange for the
surrender and cancellation of outstanding Options. Option agreements shall
contain the following terms and conditions:

                        (i)  Exercise Price; Number of Shares.  The per share
                             --------------------------------
exercise price for the Shares issuable pursuant to an Option shall be such price
as is determined by the Administrator. The Notice of Grant shall specify the
number of Shares to which it pertains.

                        (ii) Waiting Period and Exercise Dates.  At the time an
                             ---------------------------------
Option is granted, the Administrator will determine the terms and conditions to
be satisfied before Shares may be purchased, including the dates on which Shares
subject to the Option may first be purchased. The Administrator may specify that
an Option may not be exercised until the completion of the service period
specified at the time of grant. (Any such period is referred to herein as the
"waiting period.") At the time an Option is granted, the Administrator shall fix
the period within which the Option may be exercised, which shall not be earlier
than the end of the waiting period, if any.

                        (iii)  Form of Payment.  The consideration to be paid
                               ---------------
for the Shares to be issued upon exercise of an Option, including the method of
payment, shall be determined by the Administrator and may consist entirely of:

                                (1)  cash;

                                (2)  check;

                                (3)  promissory note;

                                (4)  other Shares which (A) in the case of
Shares acquired upon exercise of an Option, have been owned by the Optionee for
more than six months on the date of surrender, (B) have a Fair Market Value on
the date of surrender not greater than the aggregate exercise price of the
Shares as to which said Option shall be exercised, and (C) are of the same class
of stock as the Shares to be purchased;

                                (5)  delivery of a properly executed exercise
notice together with such other documentation as the Administrator and the
broker, if applicable, shall require to effect an exercise of the Option and
delivery to the Company of the sale or loan proceeds required to pay the
exercise price;

                                (6)  any combination of the foregoing methods of
payment; or


                                (7)  such other consideration and method of
payment for the issuance of Shares to the extent permitted by Applicable Laws .

                 (b)  Buyout Provisions.  The Administrator may at any time
                      -----------------
offer to buyout for a payment in cash, promissory note or Shares, an Option
previously granted, based on such terms and conditions as the Administrator
shall establish and communicate to the Optionee at the time that such offer is
made.

                 (c)  Method of Exercise.
                      ------------------

                        (i)  Procedure for Exercise; Rights as a Stockholder.
                             -----------------------------------------------
Any Option granted hereunder shall be exercisable at such times and under such
conditions as determined by the Administrator and as shall be permissible under
the terms of the Plan.

                      An Option may not be exercised for a fraction of a Share.

                      An Option shall be deemed to be exercised when written
notice of such exercise has been given to the Company in accordance with the
terms of the Option by the person entitled to exercise the Option and full
payment for the Shares with respect to which the Option is exercised has been
received by the Company. Full payment may, as authorized by the Administrator
and permitted by the Option Agreement, consist of any consideration and method
of payment allowable under subsection 7(a)(iii) of the Plan. Until the issuance
(as evidenced by the appropriate entry on the books of the Company or of a duly
authorized transfer agent of the Company) of the stock certificate evidencing
such Shares, no right to vote or receive dividends or any other rights as a
stockholder shall exist with respect to the Optioned Stock, notwithstanding the
exercise of the Option. No adjustment will be made for a dividend or other right
for which the record date is prior to the date the stock certificate is issued,
except as provided in Section 10 of the Plan.

                      Exercise of an Option in any manner shall result in a
decrease in the number of Shares, which thereafter shall be available, both for
purposes of the Plan and for sale under the Option, by the number of Shares as
to which the Option is exercised.


                        (ii) Termination of Employment or Consulting
                             ---------------------------------------
Relationship.  In the event an Optionee's Continuous Status as an Employee or
- ------------
Consultant terminates (other than by reason of becoming an Officer or Director
and other than upon the Optionee's death or Disability), the Optionee may
exercise his or her Option, but only within such period of time as is determined
by the Administrator at the time of grant, and only to the extent that the
Optionee was entitled to exercise it at the date of such termination (but in no
event later than the expiration of the term of such Option as set forth in the
Option Agreement). To the extent that Optionee was not entitled to exercise an
Option at the date of such termination, and to the extent that the Optionee does
not exercise such Option (to the extent otherwise so entitled) within the time
specified herein, the Option shall terminate.

                        (iii)  Disability of Optionee.  In the event an
                               ----------------------
Optionee's Continuous Status as an Employee or Consultant terminates as a result
of the Optionee's Disability, the Optionee may exercise his or her Option, but
only within twelve (12) months from the date of such termination, and only to
the extent that the Optionee was entitled to exercise it at the date of such
termination (but in no event later than the expiration of the term of such
Option as set forth in the Option Agreement). To the extent that Optionee was
not entitled to exercise an Option at the date of such termination, and to the
extent that the Optionee does not exercise such Option (to the extent otherwise
so entitled) within the time specified herein, the Option shall terminate.


                        (iv) Death of Optionee.  In the event of an Optionee's
                             -----------------
death, the Optionee's estate or a person who acquired the right to exercise the
deceased Optionee's Option by bequest or inheritance may exercise the Option,
but only within twelve (12) months following the date of death, and only to the
extent that the Optionee was entitled to exercise it at the date of death (but
in no event later than the expiration of the term of such Option as set forth in
the Option Agreement). To the extent that Optionee was not entitled to exercise
an Option at the date of death, and to the extent that the Optionee's estate or
a person who acquired the right to exercise such Option does not exercise such
Option (to the extent otherwise so entitled) within the time specified herein,
the Option shall terminate.

                 (d)  Other Provisions.  Each Option granted under the Plan may
                      ----------------
contain such other terms, provisions and conditions not inconsistent with the
Plan as may be determined by the Administrator.

          8.  Stock Purchase Rights.
              ---------------------

                 (a)  Rights to Purchase.  Stock Purchase Rights may be issued
                      ------------------
either alone, in addition to, or in tandem with other awards granted under the
Plan and/or cash awards made outside of the Plan. After the Administrator
determines that it will offer Stock Purchase Rights under the Plan, it shall
advise the offeree in writing or electronically, by means of a Notice of Grant,
of the terms, conditions and restrictions related to the offer, including the
number of Shares that the offeree shall be entitled to purchase, the price to be
paid, and the time within which the offeree must accept such offer. In no event
shall the purchase price be less than the minimum price required to assure
compliance with applicable state law. The offer shall be accepted by execution
of a Restricted Stock Purchase Agreement in the form determined by the
Administrator.

                 (b)  Repurchase Option.  Unless the Administrator determines
                      -----------------
otherwise, the Restricted Stock Purchase Agreement shall grant the Company a
repurchase option exercisable upon the voluntary or involuntary termination of
the purchaser's employment with the Company for any reason (including death or
Disability). The purchase price for Shares repurchased pursuant to the
Restricted Stock Purchase Agreement shall be the original price paid by the
purchaser and may be paid by cancellation of any indebtedness of the purchaser
to the Company. The repurchase option shall lapse at a rate determined by the
Administrator.

                 (c)  Other Provisions.  The Restricted Stock Purchase Agreement
                      ----------------
shall contain such other terms, provisions and conditions not inconsistent with
the Plan as may be determined by the Administrator in its sole discretion.

                 (d)  Rights as a Shareholder.  Once the Stock Purchase Right is
                      -----------------------
exercised, he purchaser shall have the rights equivalent to those of a
shareholder, and shall be a shareholder when his or her purchase is entered upon
the records of the duly authorized transfer agent of the Company. No adjustment
will be made for a dividend or other right for which the record date is prior to
the date the Stock Purchase Right is exercised, except as provided in Section 10
of the Plan.

          9.  Non-Transferability of Options and Stock Purchase Rights.  Unless
              --------------------------------------------------------
determined otherwise by the Administrator, Options and Stock Purchase Rights may
not be sold, pledged, assigned, hypothecated, transferred or disposed of in any
manner other than by will or by the laws of descent or distribution and may be
exercised, during the lifetime of the Optionee, only by the Optionee. If the
Administrator makes an Option or Stock Purchase Right transferable, such Option
or Stock Purchase Right shall contain such additional terms and conditions, as
the Administrator deems appropriate.


          10.  Adjustments Upon Changes in Capitalization, Dissolution, Merger,
               ---------------------------------------------------------------
Asset Sale or Change of Control.
- -------------------------------

                 (a)  Changes in Capitalization.  Subject to any required action
                      -------------------------
by the stockholders of the Company, the number and type of Shares covered by
each outstanding Option and Stock Purchase Right, and the number and type of
Shares which have been authorized for issuance under the Plan but as to which no
Options or Stock Purchase Rights have yet been granted or which have been
returned to the Plan upon cancellation or expiration of an Option or Stock
Purchase Right, as well as the price per Share covered by each such outstanding
Option or Stock Purchase Right, shall be appropriately adjusted by the Board, in
its discretion, for any increase or decrease in the number or type of issued
Shares resulting from a stock split, reverse stock split, stock dividend,
combination, conversion or reclassification, or any other increase or decrease
in the number of issued DSSG Shares or HDDG Shares. Such adjustment by the Board
shall be final, binding and conclusive. Except as expressly provided herein, no
issuance by the Company of shares of stock of any class, or securities
convertible into shares of stock of any class, shall affect, and no adjustment
by reason thereof shall be made with respect to, the number or price of Shares
subject to an Option or Stock Purchase Right.

                 (b)  Dissolution or Liquidation.  In the event of the proposed
                      --------------------------
dissolution or liquidation of the Company, to the extent that an Option or Stock
Purchase Right has not been previously exercised, it will terminate immediately
prior to the consummation of such proposed action. The Administrator may, in the
exercise of its sole discretion in such instances, declare that any Option or
Stock Purchase Right shall terminate as of a date fixed by the Administrator and
give each Optionee the right to exercise his or her Option or Stock Purchase
Right as to all or any part of the Optioned Stock, including Shares as to which
the Option or Stock Purchase Right would not otherwise be exercisable. In
addition, the Administrator may provide that any Company repurchase option
applicable to any Shares purchased upon exercise of an Option or Stock Purchase
Right shall lapse as to all such Shares, provided the proposed dissolution or
liquidation takes place at the time and in the manner contemplated.

                 (c)  Merger or Asset Sale.  In the event of a merger of the
                      --------------------
Company with or into another corporation, or the sale of substantially all of
the assets of the Company (except as otherwise provided for in Section 10(d)
below), each outstanding Option or Stock Purchase Right shall be assumed or an
equivalent Option or Stock Purchase Right substituted by the successor
corporation or a Parent or Subsidiary of the successor corporation. In the event
that the successor corporation does not agree to assume the Option or Stock
Purchase Right or to substitute an equivalent option or right, the Administrator
shall, in lieu of such assumption or substitution, provide for the Optionee to
have the right to exercise the Option or Stock Purchase Right as to all or a
portion of the Optioned Stock, including Shares as to which it would not
otherwise be exercisable. If the Administrator makes an Option or Stock Purchase
Right exercisable in lieu of assumption or substitution in the event of a merger
or sale of assets, the Administrator shall notify the Optionee that the Option
or Stock Purchase Right shall be exercisable for a period of fifteen (15) days
from the date of such notice, and the Option or Stock Purchase Right will
terminate upon the expiration of such period. For the purposes of this
paragraph, the Option or Stock Purchase Right shall be considered assumed if,
immediately following the merger or sale of assets, the Option or Stock Purchase
Right confers the right to purchase, for each Share of Optioned Stock subject to
the Option or Stock Purchase Right immediately prior to the merger or sale of
assets, the consideration (whether stock, cash, or other securities or property)
received in the merger or sale of assets by holders of Shares for each Share
held on the effective date of the transaction (and if holders were offered a
choice of consideration, the type of consideration chosen by the holders of a
majority of the outstanding Shares); provided, however, that--------if such
consideration received in the merger or sale of assets was not solely common
stock of the successor corporation or its Parent, the Administrator may, with
the consent of the successor corporation and the Optionee, provide for the
consideration to be received upon the exercise of the Option or Stock Purchase
Right, for each Share of Optioned Stock subject to the


Option or Stock Purchase Right, to be solely common stock of the successor
corporation or its Parent equal in Fair Market Value to the per share
consideration received by holders of Shares in the merger or sale of assets.

                 (d)  Other Changes to DSSG Shares or HDDG Shares.  In the event
                      -------------------------------------------
of any redemption or conversion of either DSSG Shares or HDDG Shares (including
any partial redemption or conversion), or in the event of the sale of all or
substantially all of the business represented by the either the DSSG or HDDG
Shares, or any other occurrence affecting the majority of outstanding DSSG
Shares or HDDG Shares, the Board may, if it so determines in the exercise of its
sole discretion, (i) make appropriate adjustments to the number and type of
Shares covered by each outstanding Option, Restricted Stock or Stock Purchase
Right, and the number and type of Shares which have been authorized for issuance
under the Plan but as to which no Options or Stock Purchase Rights have yet been
granted or which have been returned to the Plan upon cancellation or expiration
of an Option or Stock Purchase Right, as well as the price per Share covered by
each such outstanding Option or Stock Purchase Right under the Plan, (ii) make
outstanding Options or Stock Purchase Rights fully exercisable and vested prior
to any such redemption, conversion, sale, or other occurrence, and allow any
repurchase rights with respect to Restricted Stock to lapse, (iii) impose a date
of termination for outstanding Options or Stock Purchase Rights to occur no
later than the date of any such redemption, conversion, sale, or other
occurrence or (iv) provide for any combination of (i), (ii) and (iii) above. The
determination of the Board pursuant to this Section 10(d) shall be final,
binding and conclusive.

          11.  Date of Grant.  The date of grant of an Option or Stock Purchase
               -------------
Right shall be, for all purposes, the date on which the Administrator makes the
determination granting such Option or Stock Purchase Right, or such other later
date as is determined by the Administrator. Notice of the determination shall be
provided to each Optionee within a reasonable time after the date of such grant.

          12.  Amendment and Termination of the Plan.
               -------------------------------------

                 (a)  Amendment and Termination.  The Board may at any time
                      -------------------------
amend, alter, suspend or terminate the Plan.

                 (b)  Effect of Amendment or Termination.  No amendment,
                      ----------------------------------
alteration, suspension or termination of the Plan shall impair the rights of any
Optionee, unless mutually agreed otherwise between the Optionee and the
Administrator, which agreement must be in writing and signed by the Optionee and
the Company.

          13.  Conditions Upon Issuance of Shares.
               ----------------------------------

                 (a)  Legal Compliance.  Shares shall not be issued pursuant to
                      ----------------
the exercise of an Option or Stock Purchase Right unless the exercise of such
Option or Stock Purchase Right and the issuance and delivery of such Shares
shall comply with all relevant provisions of law, including, without limitation,
the Securities Act of 1933, as amended, the Securities Exchange Act of 1934, as
amended, the rules and regulations promulgated thereunder, Applicable Laws, and
the requirements of any stock exchange or quotation system upon which the Shares
may then be listed or quoted, and shall be further subject to the approval of
counsel for the Company with respect to such compliance.

                 (b)  Investment Representations.  As a condition to the
                      --------------------------
exercise of an Option or Stock Purchase Right, the Company may require the
person exercising such Option or Stock Purchase Right to represent and warrant
at the time of any such exercise that the Shares are being purchased only for
investment and without any present intention to sell or distribute such Shares
if, in the opinion of counsel for the Company, such a representation is
required.


          14.  Liability of Company.
               --------------------

                 (a)  Inability to Obtain Authority.  The inability of the
                      -----------------------------
Company to obtain authority from any regulatory body having jurisdiction, which
authority is deemed by the Company's counsel to be necessary to the lawful
issuance and sale of any Shares hereunder, shall relieve the Company of any
liability in respect of the failure to issue or sell such Shares as to which
such requisite authority shall not have been obtained.

          15. Reservation of Shares.  The Company, during the term of this Plan,
              ---------------------
will at all times reserve and keep available such number of Shares as shall be
sufficient to satisfy the requirements of the Plan.
