                                                               EXHIBIT 10.10(a)

                       NEW SAC 2000 RESTRICTED SHARE PLAN

1.       PURPOSE OF THE PLAN

         The purpose of the Plan is to aid New SAC (the "Company") and its
affiliates in securing and retaining key employees, directors and consultants of
outstanding ability and to motivate such employees, directors and consultants to
exert their best efforts on behalf of the Company and its affiliates by
providing incentive through the grant of restricted share awards ("Awards"). The
Company expects that it will benefit from the added interest which such key
employees and directors will have in the welfare of the Company as a result of
their proprietary interest in the Company's success.

2.       SHARES SUBJECT TO THE PLAN

         The total number of ordinary shares, par value $.0001, of the Company
(the "Ordinary Shares") that may be issued under the Plan is [ ] and the total
number of preferred shares, par value $.0001, of the Company (the "Preferred
Shares") that may be issued under the Plan is [ ] (the Ordinary Shares and the
Preferred Shares, together, the "Shares"). If any Shares awarded under the Plan
are forfeited by a Participant pursuant to the Plan, such Shares may thereafter
be reissued under the Plan.

3.       ADMINISTRATION

         The Plan shall be administered by the Compensation Committee of the
Board of Directors of the Company (the "Committee"); provided, however, that any
action permitted to be taken by the Committee may be taken by the Board of
Directors of the Company (the "Board"), in its discretion. The Committee is
authorized to interpret the Plan, to establish, amend and rescind any rules and
regulations relating to the Plan, and to make any other determinations that it
deems necessary or desirable for the administration of the Plan. The Committee
may correct any defect or omission or reconcile any inconsistency in the Plan in
the manner and to the extent the Committee deems necessary or desirable. Awards
may, in the discretion of the Committee, be made under the Plan in assumption
of, or in substitution for, outstanding awards previously granted by the Company
or its affiliates or a company acquired by the Company or with which the Company
combines. The number of Shares underlying such substitute awards shall be
counted against the aggregate number of Shares available for Awards under the
Plan. Any decision of the Committee in the interpretation and administration of
the Plan, as described herein, shall lie within its sole and absolute discretion
and shall be final, conclusive and binding on all parties concerned (including,
but not limited to, participants and their beneficiaries or successors). The
Committee shall have the full power and authority to establish the terms and
conditions of any Award consistent with the provisions of the Plan and to waive
any such terms and conditions at any time.

4.       ELIGIBILITY

         Key management and other employees, directors and consultants
of the Company and its affiliates, who are from time to time responsible for the
management, growth or protection of the business of the Company and its
affiliates, are eligible to be granted Awards under the Plan. The participants
under the Plan shall be selected from time to time by the Committee, in its
discretion, from among those eligible, and the Committee shall determine, in its
discretion, consistent with the terms of the Plan, the terms and conditions of
the Awards granted to each participant.

5.       LIMITATION

         Awards granted under this Plan shall be subject to the
following terms and conditions:

         (a)      The prospective recipient of an Award shall not, with respect
                  to such Award, be deemed to have become a participant or to
                  have any rights with respect to such Award until and unless
                  such recipient (i) shall have executed an Agreement or other
                  instrument evidencing the Award and its terms and conditions
                  and delivered a fully executed copy thereof to the Company,
                  (ii) shall become a signatory to the Management Shareholders
                  Agreement dated as of November 22, 2000 among the Company and
                  certain individuals identified therein and (iii) otherwise
                  complied with the then applicable terms and conditions under
                  the Plan.

         (b)      The name of each participant will be entered into the Register
                  of Members and each participant shall be issued a certificate
                  in respect of restricted shares awarded under the Plan. Such
                  certificate shall be registered in the name of the
                  participant, and shall bear an appropriate legend referring to
                  the terms, conditions and restrictions applicable to such
                  Award substantially in the following form:

                  "THE TRANSFERABILITY OF THIS CERTIFICATE AND THE SHARES
                  REPRESENTED HEREBY ARE SUBJECT TO THE TERMS AND CONDITIONS
                  (INCLUDING FORFEITURE) OF THE NEW SAC 2000 RESTRICTED SHARE
                  PLAN AND AN AGREEMENT ENTERED INTO BETWEEN THE REGISTERED
                  OWNER AND NEW SAC. COPIES OF SUCH PLAN AND AGREEMENT ARE ON
                  FILE IN THE OFFICES OF THE SECRETARY OF NEW SAC."

         (c)      All certificates for restricted shares delivered under this
                  Plan shall be subject to such share transfer orders and other
                  restrictions as the Committee may deem advisable under the
                  rules, regulations and other requirements of the Securities
                  and Exchange Commission, any stock exchange upon which the
                  Company's Shares are then listed and any applicable federal or
                  state securities law, and the Committee may cause a legend or
                  legends to be put on any such certificates to make appropriate
                  reference to such restrictions.

         (d)      The Committee may adopt rules which provide that the share
                  certificates evidencing such shares may be held in custody by
                  a bank or other institution, or that the Company may itself
                  hold such shares in custody until the restrictions thereon
                  shall have lapsed, and may require as a


                                       2
<PAGE>

                  condition of any Award that the participant shall have
                  delivered a stock power endorsed in blank relating to the
                  share covered by such Award.

         (e)      Until such time as the Company is subject to the periodic
                  reporting requirements of Section 13 or 15(d) of the
                  Securities Exchange Act of 1934, the Company shall deliver a
                  balance sheet and an income statement at least annually to
                  each individual holding Shares issued under the Plan, unless
                  such individual is a key employee of the Company or its
                  Affiliates whose duties in connection with the Company (or any
                  Affiliate) assure such individual access to equivalent
                  information.

7.       RESTRICTIONS AND FORFEITURES

         The Shares awarded pursuant to the Plan shall be subject to the
following restrictions and conditions:

         (a)      During a period set by the Committee of no more than ten years
                  commencing with the date of an Award (the "Restriction
                  Period"), the participant will not be permitted to sell,
                  transfer, pledge, assign or otherwise dispose of restricted
                  shares awarded pursuant to such Award. If a participant's
                  employment by the Company should terminate for any reason
                  during the Restriction Period, unless otherwise provided by
                  the Committee, the participant shall forfeit the restricted
                  shares and it shall be returned to the Company in full and
                  cancelled. However, such forfeiture provisions shall in all
                  events lapse as to the Shares issued to each participant at
                  the rate not less than twenty percent (20%) of those Shares
                  per year of service over the five (5)-year period measured
                  from the issue date of the Shares and shall immediately lapse
                  as all the Shares issued to the participant upon the
                  termination of his or her service by reason of death or
                  permanent disability. Within these limits the Committee may
                  provide for the lapse of such restrictions in installments
                  where deemed appropriate.

         (b)      Except as provided in Section 7(a), the participant shall have
                  with respect to the restricted shares all of the rights of a
                  shareholder of the Company, including the right to vote the
                  shares and receive dividends and other distributions;
                  provided, however, that distributions (other than tax
                  distributions) with respect Shares subject to the Restriction
                  Period, shall be held by the Company and distributed upon
                  vesting.

         (c)      The Committee may impose any conditions on an Award it deems
                  advisable to ensure the participant's payment to the Company
                  of any federal, state or local taxes required to be withheld
                  with respect to such Award.

         (d)      If the Company provides for the repurchase of the Shares, the
                  purchase price for such Shares shall be deemed reasonable if
                  (1) it is not less than the fair market value of the
                  securities to be repurchased on the date of


                                       3
<PAGE>

                  termination of employment and the right to repurchase is
                  exercised for cash or cancellation of purchase money
                  indebtedness for the Shares within 90 days of termination of
                  employment, and the right terminates when the Company's
                  securities become publicly traded or (2) it is at the original
                  purchase price, provided that the right to repurchase at the
                  original purchase price lapses at the rate of at least 20% of
                  the Shares per year over 5 years from the date the Award is
                  granted and the right to repurchase must be exercised for cash
                  or cancellation of purchase money indebtedness for the Shares
                  within 90 days of termination of employment; provided, that
                  the securities held by an officer, director , or consultant of
                  the Company may be subject to additional or greater
                  restrictions than those provided in (1) and (2) above.

8.       ADJUSTMENTS UPON CERTAIN EVENTS

         Notwithstanding any other provisions in the Plan to the contrary, the

without limitation, the repayment of Company indebtedness by an affiliate or
shareholder, or any distribution to shareholders of Shares or the receipt of
proceeds from the sale or other disposition of a subsidiary of the Company other
than regular cash dividends or any transaction similar to the foregoing, the

if the Award is not assumed, substituted or otherwise continued following the
Change in Control, the restrictions on the Award shall lapse immediately prior

disposition, in one or a series of related transactions, of all, or

consent of a participant, would diminish any of the rights under any Award
theretofore granted to such participant under the Plan; provided, however, that
the Board or the Committee may amend the Plan in such manner as it deems
necessary to permit the granting of Awards meeting the requirements of the Code
or other applicable laws.
