Apex Corporation pursuant to this Agreement, Apex Corporation shall receive a
fee in an amount equal to the direct and indirect costs incurred by Apex
Corporation in providing such services to the Apex Group (including, without
limitation, personnel costs, travel and expenses for fees and disbursements of
third parties and all overhead expenses), plus ten percent (10%) of such costs
(such fee, the "Service Fee").
                -----------   

                                      -3-

 
          (b) Unless paragraph 5(c) applies, the Service Fee shall be allocated
to each entity comprising the Apex Group in the following manner:  time devoted
to any specific Apex Group entity and time devoted to the Apex Group as a whole.

          (c) The parties hereby agree that if a method of allocating and
apportioning the Service Fee among the members of the Apex Group exists that is
more appropriate than the method set forth in paragraph 5(b) above, such method
shall be implemented and this Agreement shall be modified accordingly.  Factors
to be considered in establishing a different method of allocation and
apportionment shall include, total expenses, asset size, sales, payroll and the
level of expertise of each Apex Group member.

          (d) Apex Corporation shall establish and maintain a system that
identifies all costs related to the services provided under this Agreement.  The

month shall be the prorated portion thereof for the actual number of days.

          (f) In the event that Apex Corporation needs an advance with respect
to the Service Fee in order to render the services set forth herein to the Apex
Group, such advance shall be provided to Apex Corporation upon the consent of
the board of directors of Apex Limited.  Such advance shall be credit against

relevant Apex Group entities) in a manner mutually agreeable by the parties.

          (g) The parties hereto agree that the documentation as required
pursuant to Sections 6038A and 6662(e) of the Code shall be prepared as soon as
practicable and be maintained in order to establish and support the Service Fee.

          ---------------                                                  
restrict Apex Corporation's ability to provide services to parties other than
members of the Apex Group, provided that if any such services rendered to a
party other than a member of the Apex Group are similar to the services rendered
to members of the Apex Group under this Agreement, the provision of such
services shall require the prior consent of the board of directors of Apex
Limited.

     7.   Exculpation and Indemnification of Apex Corporation.  (a)  To the
          ---------------------------------------------------              
fullest extent permitted by law, none of Apex Corporation or its officers,
directors or employees (each an "Exculpated Party") shall be liable to the Apex
                                 ----------------                              
Group for (i) any act or omission taken or suffered by such Exculpated Party in
connection with the conduct of the business of the Apex Group in connection with
this Agreement, (ii) the rendering of advice to the Apex Group, (iii) the
provision of other services by such Exculpated Party in accordance herewith,
(iv) any

                                      -4-

 
action or omission taken or suffered by the Apex Group;  provided, that such
limitation from any liability shall not apply to any Exculpated Party that is
not a natural person to the extent of any such Exculpated Party's gross
negligence, willful misconduct or bad faith (or the gross negligence, willful
misconduct or bad faith of any shareholder, member, officer, director or
employee of such Exculpated Party) in complying with the material terms of this
Agreement.  To the extent that, at law or in equity, any Exculpated Party has
duties (including fiduciary duties) and liabilities relating thereto to the Apex
Group, such Exculpated Party acting under this Agreement shall not be liable to
the Apex Group for its good faith reliance on the provisions of this Agreement.
The provisions of this Agreement, to the extent that they restrict the duties
and liabilities of an Exculpated Party otherwise existing at law or in equity,
are agreed by the parties hereto to modify to that extent such other duties and
liabilities of such Exculpated Party.

          (b) An Exculpated Party may consult with legal counsel, accountants or
professional advisors selected by it with reasonable care, and any act or
omission taken or suffered by it on behalf of the Apex Group in furtherance of
the business of the Apex Group in good faith in reliance on and in accordance
with the advice of such counsel, accountants or professional advisors shall be
full justification for the act or omission, and the Exculpated Party shall be
fully protected in so acting or omitting to act provided such counsel,
accountants or professional advisors were selected with reasonable care.

          (c) Subject to Section 7(e) hereof, to the fullest extent permitted by
law, Apex LDC shall indemnify and save harmless Apex Corporation, and its
officers, directors or employees (each, an "Indemnified Party") from and against
                                            -----------------                   
any and all claims, liabilities, damages, losses, costs and expenses (including
amounts paid in satisfaction of judgments, in compromises and settlements, as
fines and penalties and legal or other costs and expenses of investigating or
defending against any claim or alleged claim but excluding any liabilities for
taxes of any Indemnified Party) of any nature whatsoever, known or unknown,
liquidated or unliquidated, that are incurred by such Indemnified Party and
arise out of or in connection with the business of the Apex Group or the
performance by such Indemnified Party of its responsibilities hereunder
(including, without limitation, those that arise out of or in connection with
the employment by Apex Corporation of advisors, agents or other third parties to
assist Apex Corporation in the performance of its duties pursuant to this
Agreement) (each of the foregoing, a "Claim");  provided, that an Indemnified
                                      -----                                  
Party shall not be entitled to indemnification hereunder to the extent such
Claim arises from such Indemnified Party's gross negligence, willful misconduct
or bad faith with respect to material terms of this Agreement.  The termination
of any proceeding by settlement, judgment, order or upon a plea of nolo
contendere or its equivalent shall not, of itself, create a presumption that an
Indemnified Party was grossly negligent or engaged in willful misconduct or bad
faith.  Any Person entitled to indemnification from Apex LDC hereunder shall
obtain the written consent of Apex LDC (which consent shall not be unreasonably
withheld) prior to entering into any agreement or settlement which would result
in an obligation of the Apex Group to indemnify such Person; provided, that any
Person entitled to indemnification hereunder may enter into an agreement or
settlement without the written consent of Apex LDC on the condition that the
right of such Indemnified Party to indemnification by Apex LDC is irrevocably
waived.

          (d) Expenses incurred by an Indemnified Party in defense or settlement
of any Claim that may be subject to a right of indemnification hereunder may be
advanced by

                                      -5-

 
Apex prior to the final disposition thereof upon receipt of an undertaking by or
on behalf of the Indemnified Party to repay such amount to the extent that it
shall be determined ultimately that such Indemnified Party is not entitled to be
indemnified hereunder. The right of any Indemnified Party to the indemnification
provided herein shall be cumulative of, and in addition to, any and all rights
to which such Indemnified Party may otherwise be entitled by contract or as a
matter of law or equity and shall be extended to such Indemnified Party's
successors, assigns and legal representatives.

          (e) Promptly after receipt by an Indemnified Party of notice of the
commencement of any action or proceeding or threatened action or proceeding in
connection with any Claim referred to in Section 7(c), such Indemnified Party
shall give written notice thereof to the Apex Group; provided, that the failure
of an Indemnified Party to give such notice shall not relieve Apex LDC of its
obligations pursuant to Section 7(c) hereof, except to the extent that the Apex
Group is actually prejudiced by such failure to give notice.

          (f) In case any action or proceeding is commenced against any
Indemnified Party which may be subject to indemnification pursuant to this
Section 7, the Apex Group shall have the right to assume the defense thereof,
with counsel reasonably satisfactory to such Indemnified Party.  After notice
from Apex LDC to such Indemnified Party of Apex LDC's election to assume the
defense thereof, Apex LDC will be liable for the expenses subsequently incurred
by such Indemnified Party in connection with the defense thereof.  Apex LDC will
not consent to the entry of any judgment or enter into any settlement which does
not include as an unconditional term the giving to such Indemnified Party a
release from all liability in respect of such Claim.

          (g) Any person who is not a party to this Agreement may be required,
prior to being paid any amount under this Section 7, to agree to the provisions
of this Section 7 applicable to Indemnified Parties.

          (h) Any claims which may be the subject of a right of indemnification
pursuant to this Section 7 shall be subject to verification by an independent
accountant acceptable both to the party giving and the party receiving
indemnification.

     8.   Term and Termination.  (a)  This Agreement shall become effective as
          --------------------

termination or removal pursuant to subsections 8(b) and 8(c) below.

     (b)  The Apex Group may terminate this Agreement or remove Apex
Corporation at any time upon 30 days' written notice to Apex Corporation

     (c)  Apex Corporation may terminate this Agreement at any time by
delivering to Apex LDC (with a copy to Apex Limited's Board of Directors) a
notice to that effect (the "Resignation Notice").  Apex Corporation's
                            ------------------                       
resignation shall be effective on the 90th day following the receipt of the
Resignation Notice by Apex LDC (the "Resignation Date").
                                     ----------------   

                                      -6-

 
       (d)  If the Resignation Date is a date other than the end of a calendar
month, at the start of the calendar month in which the Resignation Date will
occur, Apex LDC shall pay to Apex Corporation the amount of its Services Fee
allocable to that portion of the calendar month which is prior to the
Resignation Date.

       (e)  The provisions of Section 7 shall survive the termination of this
Management Services Agreement.

       9.   Independent Contractor Status.    This Agreement is intended to
            -----------------------------                                  
create, and creates, a contractual relationship for services to be rendered by
Apex Corporation acting in the ordinary course of its business as independent
contractor and is not intended to create, and does not create, a partnership,
joint venture or any like relationship among the parties hereto (or any other
parties).

       10.  Arbitration.  Any dispute or disagreement which may arise under, or
            -----------                                                        
as a result of, or in any way relate to, the interpretation, construction or
application of this Agreement shall be determined by binding arbitration.  The
parties may agree to submit the matter to a single arbitrator or to several
arbitrators, may require that arbitrators possess special qualifications or
expertise or may agree to submit a matter to a mutually acceptable firm of
experts for decision.  In the event the parties shall fail to thus agree upon
terms of arbitration within twenty (20) days from the first written demand for
arbitration, then such disputed matter shall be settled by arbitration under the
Rules of the American Arbitration Association, by three arbitrators appointed in
accordance with such Rules.  Such arbitration shall be held in New York, New
York.  Once a matter has been submitted to arbitration pursuant to this section,
the decision of the arbitrators reached and promulgated as a result thereof
shall be final and binding upon all parties.  The cost of arbitration shall be
shared equally by Apex Limited and the Consultant and each party shall pay the
expenses of its attorneys, except that the arbitrators shall be entitled to
award the costs of arbitration, attorneys' and accountants' fees, as well as
costs, to the party that they determine to be the prevailing party in any such
arbitration.
