                         SECOND AMENDED AND RESTATED
                            OPERATING AGREEMENT
                                    OF
                           SLINGSHOT NETWORKS, LLC

     This SECOND AMENDED AND RESTATED  OPERATING  AGREEMENT (the "Agreement") is
entered  into as of June 21,  2000,  between  Anschutz  Digital  Media,  Inc., a
Colorado corporation ("ADMI"), and U.S. Telesource, Inc., a Delaware corporation
("UST"),  both of which are referred to as the "Members" and  individually  as a
"Member."

     A limited liability company was formed in accordance with the provisions of
the  Delaware  Limited  Liability  Company  Act (the  "Act")  under  the name of
Slingshot  Networks,  LLC (the "Company") pursuant to a Certificate of Formation
filed  July 14,  1999,  with the  Delaware  Secretary  of  State.  An  Operating
Agreement of the Company was entered into as of that same date, under which ADMI
was the sole member.  Pursuant to a Subscription  Agreement by and between Qwest
Communications  International Inc., a Delaware  corporation  ("Qwest"),  and the
Company  dated as of October  22,  1999 (the  "Subscription  Agreement"),  Qwest
agreed to purchase an equity interest in the Company. Additionally,  ADMI agreed
under a  Contribution  Agreement  dated as of October 22, 1999 by and among ADMI
and the Company (the "Contribution Agreement") to contribute certain assets (the
"ADMI Contributed  Assets") to the Company. In conjunction with the Subscription
Agreement  and the  Contribution  Agreement,  on October 22, 1999 ADMI and Qwest
entered into an Amended and Restated Operating  Agreement.  Subsequently,  Qwest
transferred  its  interest in the  Company to its wholly  owned  subsidiary  UST
(references to UST herein shall be deemed to include Qwest as its predecessor in
interest).  On June __, 2000 ADMI and UST entered into a Unit Purchase Agreement
(the "Purchase  Agreement")  pursuant to which UST purchased a portion of ADMI's
equity  interest in the Company in exchange for cash and a promissory  note (the
"Purchase Note"). In light of the foregoing, the Members now desire to amend and
restate  the  Amended  and   Restated   Operating   Agreement  of  the  Company.
Accordingly,  from and after the date hereof, the affairs of the Company will be
governed  by  this  Second  Amended  and  Restated   Operating   Agreement.   In
consideration of the foregoing, and of the mutual promises contained herein, the
Members agree as follows:

          Company shall have two classes of Units:  Class A and Class B. The two
          classes of Units shall be identical  in all respects  except for their
          respective Voting Interests.  The number of Units owned by each Member
          shall be determined  in  connection  with the issuance of a membership
          interest in the Company in exchange for the capital  contribution made
          by such  Member.  Initially  the  Units  shall not be  represented  by

                                CAPITAL CONTRIBUTIONS

     3.1  Initial Capital Contributions.

          (a)  In accordance with the terms of the Contribution Agreement,  ADMI
               contributed  to the Company all of its right,  title and interest
               in and to the  ADMI  Contributed  Assets.  As a  result  of  such
               contribution,  ADMI was initially credited with a capital account
               equal to $84,816,696, and received 84,816,696 Class A Units.

          (b)  In accordance with the terms of the Subscription  Agreement,  UST
               contributed  to the  Company,  a  promissory  note (the  "Capital
               Note") in the amount of  $84,816,696,  and such  amount  shall be
               credited to UST's  capital  account  when and as the  payments of
               principal  are made on the  Capital  Note.  As a result  of UST's
               agreement  to  make  such   contribution   and  pursuant  to  the
               Subscription  Agreement,  UST was  admitted  as a  Member  of the
               Company, and received 84,816,696 Class A Units.

          (c)  Since  October 22,  1999,  each of UST and ADMI have made contri-
               butions of $11,578,518.50 to their respective capital accounts in
               exchange for  11,578,518  Class A Units.  In accordance  with the
               terms of the Purchase Agreement,  UST acquired 48,197,607 Class A
               Units from ADMI in exchange for cash and the Purchase  Note. As a
               result,  48,197,607  Class A Units were  transferred from ADMI to
               UST.

          (d)  As a result of the transactions  described above, the Members own
               the number and classes of Units and have capital account balances
               attributable to the Units as set forth below:


                                                                          

- ------------------------------- ------------------------- ------------------------ -----------------------------------

                                     Class A Units             Class B Units       Capital Account Balance
- ------------------------------- ------------------------- ------------------------ -----------------------------------
ADMI                                   48,197,607                   -0-                        $48,197,607
- ------------------------------- ------------------------- ------------------------ -----------------------------------
UST                                   144,592,821                   -0-                        $59,776,125
- ------------------------------- ------------------------- ------------------------ -----------------------------------


          (e)  Based on the above,  the  Sharing  Ratio of ADMI is 25%,  and the
               Sharing Ratio of UST is 75%.

     3.2  Additional Capital Contributions.

          (a)  If, from time to time in the  reasonable  judgment of the Manage-
               ment Committee,  the Company requires  additional capital for any
               purpose,  the Management  Committee is hereby authorized to cause
               the Company to issue  additional  Units,  on terms and conditions
               and with  repayment  priorities  as  approved  by the  Management
               Committee.  Notwithstanding  the  foregoing,  until a third party
               becomes a Member,  Units  shall not be issued at a price per Unit
               that is less than $1.00.

          (b)  If the Company desires to issue  additional Units pursuant to (a)
               above,  the  Company  hereby  grants to the  Members the right of
               first refusal to purchase a pro rata share (equaling the Member's
               respective  Sharing Ratio on the day before such additional Units
               are to be  issued)  of the  additional  Units  which the  Company
               proposes  to  issue.  If  the  Company  proposes  to  issue  such
               additional Units, it shall give the Members written notice of its
               intention,  describing the price and terms upon which the Company
               proposes to issue the Units.  Each Member shall have 15 days from
               the date such  notice is sent by the Company to agree to purchase
               the portion of the  additional  Units issued which it is entitled
               to purchase  for the price and upon the terms so specified in the
               notice.  Such notice  shall be in writing  and shall  specify the
               quantity of additional Units to be purchased. If any Member fails
               to exercise the right of first refusal  within the 15-day period,
               the  Company  shall  have the right  thereafter  to sell or issue
               those  additional  Units  upon  terms  no more  favorable  to the
               purchasers  of  the  additional   Units  than  specified  in  the
               Company's notice to Members.

     3.3  Return  of  Capital  Contributions.  Capital  contributions  shall  be
          expended in furtherance of the business of the Company.  All costs and
          expenses  of the  Company  shall be paid from its funds.  No  interest
          shall be paid on  capital  contributions.  No  Manager  shall have any
          personal liability for the repayment of any capital  contribution to a
          Member.

     3.4  Loans.

          (a)  The Company may borrow  additional  capital from any source,  in-
               cluding any Member.  No Member  shall be obligated to make a loan
               to the Company.

          (b)  If from time to time in the  reasonable  judgment  of the Manage-
               ment Committee the Company  requires  additional  capital for any
               purpose  related to the business of the Company,  the  Management
               Committee  is  authorized  to cause the  Company  to borrow  such
               capital,  on terms and  conditions as approved by the  Management
               Committee.  If the  Management  Committee  decides to borrow such
               capital from a Member (the "Loan  Amount"),  each Member shall be
               given the  opportunity,  but shall not be obligated,  to loan its
               share of the Loan Amount to the Company.  A Member's share of the
               Loan Amount shall be the Loan Amount  multiplied  by the Member's
               Sharing  Ratio.  The loans  shall be made  within  10 days  after
               request by the Management Committee to the Members.  Such request
               shall be in  writing  and shall  specify  the  amount of the Loan
               Amount.  If a Member  does not loan its share of the Loan  Amount
               (the "Shortfall Amount") and the other Member does loan its share
               (a "Participating  Member"),  the Participating Member shall have
               the right,  exercisable  within 10 days after notice, to loan the
               Company  the  Shortfall  Amount.  The loans to the Company by the
               Participating Members shall be unsecured, evidenced by promissory
               Note of the Company,  shall accrue  interest at a rate determined
               by the Management Committee, shall be payable on a pro rata basis
               solely from Cash Flow prior to any distributions to Members,  and
               shall not contain any default interest or penalty provisions.

          Members in amounts  deemed  appropriate  by the  Management  Committee

          4.2, all distributions of Cash Flow shall be made among the Members in
          accordance with their respective Sharing Ratios.

     4.2  Liquidating Distributions. All distributions made in connec- tion with
          the sale or exchange of all or substantially all of the Company assets
          and all  distributions  made in connection with the liquidation of the
          Company shall be made to the Members in accordance with their relative
          capital account balances at the time of distribution.

                                        ARTICLE 5

                               ALLOCATION OF PROFIT AND LOSS

     5.1  Determination of Profit and Loss. Profit or Loss shall be de- termined
          on an annual basis and for such other periods as may be required.

     5.2  Loss  Allocation.  Except as  provided in Section  5.4,  Loss shall be
          allocated among the Members in accordance with their relative  Sharing
          Ratios.

     5.3  Profit Allocation.

          (a)  Except as provided  in Section  5.3(b) and  Section  5.4,  Profit
               shall be  allocated  among the Members in  accordance  with their
               relative Sharing Ratios.

          (b)  Any Profit with respect to the sale,  exchange or other  disposi-
               tion of all or  substantially  all of the Company  assets or with
               respect to the  liquidation  of the  Company  shall be  allocated
               among the  Members so that their  capital  account  balances  are
               proportionate to their Sharing Ratios.

          (c)  For  purposes  of Section  5.3(b),  the  capital  accounts of the
               Members  shall  be   determined   (i)  before  giving  effect  to
               distributions  under Section 4.2; (ii) after allocating all other
               items  of  Profit   and  Loss;   and  (iii)   after   making  all
               distributions under Section 4.1.

     5.4  Regulatory Allocations and Curative Provision.

          (a)  The "qualified income offset"  provisions of Treasury  Regulation
               Section  1.704-1(b)(2)(ii)(d)  are  incorporated  herein  by ref-
               erence  and shall  apply to adjust the  allocation  of Profit and
               Loss  otherwise  provided  for under  Sections 5.2 and 5.3 to the
               extent provided in that regulation.

          (b)  The "minimum  gain"  provisions  of Treasury  Regulation  Section
               1.704-2 are  incorporated  herein by reference and shall apply to
               adjust the allocation of Profit and Loss  otherwise  provided for
               under  Sections  5.2  and  5.3 to the  extent  provided  in  that
               regulation.

          (c)  Notwithstanding  the  provisions  of Section  5.2,  if during any
               fiscal  year  of  the  Company  the  allocation  of any  loss  or
               deduction,  net of any income or gain, to a Member would cause or
               increase a negative  balance in a Member's  capital account as of
               the end of that  fiscal  year,  only the  amount  of such loss or
               deduction  that reduces the balance to zero shall be allocated to
               the Member and the  remaining  amount  shall be  allocated to the
               other  Member.  For the  purpose  of the  preceding  sentence,  a
               capital account shall be reduced by the adjustments,  allocations
               and  distributions  described  in  Treasury  Regulations  Section
               1.704-1(b)(2)(d)(4), (5) and (6), and increased by the amount, if
               any,  that the Member is  obligated  to  restore to the  Member's
               capital account within the meaning of Treasury Regulation Section
               1.704-1(b)(2)(ii)(c)  as of that time or is deemed  obligated  to
               restore  under  Treasury  Regulation  Section   1.704-2(g)(1)  or
               Section 1.704-2(i)(5).

          (d)  All  allocations  pursuant to the  foregoing  provisions  of this
               Section 5.4 (the  "Regulatory  Allocations")  shall be taken into
               account in computing  allocations  of other items under  Sections
               5.2 and 5.3, including,  if necessary,  allocations in subsequent
               fiscal years,  so that the net amounts  reflected in the Members'
               capital accounts and the character for income tax purposes of the
               taxable income recognized (e.g., as capital or ordinary) will, to
               the extent possible, be the same as if no Regulatory  Allocations
               had been given effect.

                             ALLOCATION OF TAXABLE INCOME AND LOSS

     6.1  In General.

          (a)  Except as provided  in Section  6.2,  each item of income,  gain,
               loss and  deduction  of the Company  for federal  income tax pur-
               poses shall be allocated  among the Members in the same manner as
               such item is allocated for capital account purposes under Article
               5.

          (b)  To the  extent of any  recapture  income (as  defined  below) re-
               sulting from the sale or other taxable  disposition  of a Company
               asset, the amount of any gain from such disposition  allocated to
               (or  recognized  by) a Member (or its  successor in interest) for
               federal  income  tax  purposes  shall be  deemed  to  consist  of
               recapture  income to the extent  such  Member  (or such  Member's
               predecessor  in interest)  has been  allocated or has claimed any
               deduction  directly or indirectly giving rise to the treatment of
               such  gain as  recapture  income.  For this  pu- pose  "recapture
               income"  shall  mean  any gain  recognized  by the  Company  (but
               computed  without regard to any adjustment re- quired by sections
               734 and 743 of the Code) upon the  disposi-  tion of any property
               or asset of the Company that does not constitute capital gain for
               federal  income tax  purposes  because such gain  represents  the
               recapture  of  deductions  previously  taken with respect to such
               property or assets.

     6.2  Allocation of Section  704(c) Items.  The Members  recognize that with
          respect to  property  contributed  to the  Company by a Membe and with
          respect to property  revalued in accordance with Trea- sury Regulation
          Section  1.704-1(b)(2)(iv)(f),  there will be a difference between the
          agreed  values or  "carrying  values" of such  property at the time of
          contribution  or  revaluation  and  the  adjusted  tax  basis  of such
          property at that time. All items of tax  depreciation,  cost recovery,
          amortization,  amount  realized  and gain or loss with respect to such
          assets shall be  allocated  among the Members to take into account the
          book-tax  disparities  in accordance  with the  provisions of sections
          704(b) and 704(c) of the Code and the Treasury Regulations under those
          sections.

     6.3  Integration  With  Section 754  Election.  All items of income,  gain,
          loss,  deduction  and credit  recognized  by the  Company  for federal
          income tax purposes and  allocated to the Members in  accordance  with
          the provisions  hereof and all basis  allocations to the Members shall
          be determined  without regard to any election under section 754 of the
          Code  that  may  be  made  by the  Company;  provided,  however,  such
          allocations,  once made, shall be adjusted as necessary or appropriate
          to take into account the adjustments permitted by sections 734 and 743
          of the Code.

                                       ARTICLE 7

                                       MANAGEMENT

     7.1  Management Committee.

          (a)  Management  of  the  Company  shall  be  vested  in a  management
               committee (the  "Management  Committee").  Until such time as the
               Purchase  Note is paid in  full  by UST in  accordance  with  its
               terms,  the  Management  Committee  shall  consist of six members
               (each, a "Manager"), three of whom shall be appointed by ADMI and
               three  of  whom  shall  be  appointed  by  UST.   Upon  the  full
               satisfaction  of the Purchase Note in accordance  with its terms,
               the Management Committee shall consist of nine Managers, three of
               whom shall be appointed by ADMI,  four of whom shall be appointed
               by UST,  one of  whom  shall  be  appointed  by  ADMI  and UST as
               mutually agreed upon and one of whom shall be the Chief Executive
               Officer of the  Company.  Subject to the  limitations  of Section
               8.9, the Management  Committee shall have the exclusive power and
               authority to conduct the business of the Company.  In  conducting
               the business of the Company,  the Management Committee shall have
               all rights,  duties and powers  conferred  by the Act,  except as
               limited  hereby.  The  Management  Committee is hereby  expressly
               authorized  on behalf of the Company to make all de- cisions with
               respect  to the  Company's  business  and  to  take  all  actions
               necessary to carry out such decisions. No actions shall be taken,
               nor any decisions  made, by any Manager or officer of the Company
               without  the  prior  approval  of,  or  pursuant  to  an  express
               delegation of authority by, the Management Committee.  Subject to
               the limitations of Section 8.9 and clauses (b) and (c) below, the
               act of the  majority of the members of the  Management  Committee
               shall be the act of the Management Committee. Notwithstanding the
               foregoing,  all documents  executed on behalf of the Company need
               only be signed by a Manager or by an officer of the  Company  who
               has been given the power and authority to do so by the Management
               Committee.

          (b)  The  Management   Committee  shall  have  the  power  to  appoint
               individuals  to  serve  as the  Chief  Executive  Officer,  Chief
               Financial Officer and Chief Operating Officer of the Company.  In
               addition,  the  Management  Committee  shall  have  the  right to
               delegate  all or portions of its  management  authority to one or
               more  officers of the Company.  Any officer may be removed or its
               authority  withdrawn  at any  time by the  Management  Committee.
               Notwithstanding  any other provision of this Operating  Agreement
               to the contrary,  until such time as the Purchase Note is paid in
               full by UST in accordance with its terms (i) no individual may be
               appointed  or  terminated  as  Chief  Executive  Officer,   Chief
               Financial  Officer  or Chief  Operating  Officer  of the  Company
               without the prior approval of the Managers appointed by ADMI (the
               "ADMI Managers"),  and (ii) all determinations as to compensation
               and  benefits  to be  paid  or  granted  to the  Chief  Executive
               Officer, Chief Financial Officer or Chief Operating Officer shall
               require the approval of the ADMI Managers.

          (c)  Until  such time as the  Purchase  Note is paid in full by UST in
               accordance with its terms, without the prior approval of the ADMI
               Managers,  the Company may not directly or  indirectly  through a
               subsidiary or other controlled entity (i) incur  Indebtedness (as
               defined below) for an amount  individually or in the aggregate in
               excess of $10 million,  (ii) issue equity interests or securities
               for  consideration  individually or in the aggregate in excess of
               $10 million,  (iii) make any single capital expenditure in excess
               of $2 million,  (iv) acquire or dispose of assets with a value in
               excess of $2 million in any single  transaction,  (v)  approve or
               enact any  annual  budget of the  Company or (vi) amend or repeal
               any material provision of the Company's Operating Agreement.  For
               purposes  of this  Agree-  ment,  "Indebtedness"  shall mean with
               respect to any person,  without duplication,  all indebtedness in
               respect of money  borrowed,  including  without  limitation,  all
               obligations   under   capital   leases,   all   synthetic   lease
               obligations,  the  deferred  purchase  price of any  property  or
               services,  the aggregate face amount of all surety bonds, letters
               of  credit,  and  bankers'  acceptances,   and  all  payment  and
               reimbursement  obligations  in  respect  thereof  whether  or not
               matured,  evidenced  by a  promissory  note,  bond,  debenture or
               similar  written  obligation for the payment of money  (including
               reimbursement  agreements and conditional  sales or similar title
               retention  agreements),  including all such items incurred by any
               partnership or joint venture as to which such person is liable as
               a general  partner or joint  venturer,  other than trade payables
               and accrued expenses incurred in the ordinary course of business.

     7.2  Management Committee Meetings.

          (a)  The  Management  Committee will hold regular  quarterly  meetings
               without  call or notice at such time as will from time to time be
               fixed by standing resolution of the Management Committee.

          (b)  Special meetings of the Management Committee may be called by any
               two  Managers.  All meetings will be held upon 10 days' notice by
               mail or 72 hours' notice delivered personally or by tel- phone or
               facsimile.  A notice need not specify the purpose of any meeting.
               Notice of a special  meeting need not be given to any Manager who
               signs a waiver of notice or a consent to holding  the  meeting or
               an approval of the minutes  thereof,  whether before or after the
               meeting, or who attends the meeting without protesting,  prior to
               its  commencement,  the lack of notice to such Manager.  All such
               waivers,  consents and  approvals  will be filed with the Company
               records or made a part of the minutes of the meeting.

          (c)  Meetings  of the  Management  Committee  may be held at any place
               within or  without  the State of  Delaware  that has been  desig-
               nated in the  notice of the  meeting  or at such  place as may be
               approved by the Management Committee. Managers may participate in
               a  meeting  through  use  of  conference   telephone  or  similar
               communications  equipment,  so long as all Managers participating
               in such meeting can hear one another.  Participation in a meeting
               in such manner constitutes a presence in person at such meeting.

          7.3  Duties.  The Managers shall carry out their duties in good faith,
               in a manner the Managers  believe to be in the best  interests of
               the Company,  and with such care as an ordinarily  prudent person
               in a like  position  would use  under  similar  circumstances.  A
               Manager who so performs its duties  shall not have any  liability
               by reason of being or having been a Manager of the Company.

          7.4  Time  Devoted to  Business.  The Members and the  Managers  shall
               devote such time to the business of the Company as they, in their
               discretion,  deem necessary for the efficient  carrying on of the
               Company's  business.  The Members and the  Managers  shall at all
               times be free to engage  for their own  account  in any  business
               that competes with any business of the Company.

          7.5  Reliance  by Third  Parties.  No  third  party  dealing  with the
               Company  shall be  required to  ascertain  whether any Manager is
               acting in accordance with the provisions of this  Agreement.  All
               third parties may rely on a document executed by a Manager (or an
               officer duly authorized by the Management  Committee to exe- cute
               such document) as binding the Company. The foregoing pro- visions
               shall not apply to third parties who are  affiliates of a Member,
               the Managers,  or an officer of the Company. A Manager or officer
               acting without  authority  shall be liable to the Members for any
               damages arising out of its unauthorized actions.

          7.6  Resignation.  Any  Manager  may be  removed  at any time  with or
               without  cause by the  Member who  appointed  such  Manager.  Any
               Manager  may resign at any time by giving  written  notice to the
               Members.  Unless  otherwise  specified in the notice,  the resig-
               nation  shall take effect upon  receipt by the  Members,  and the
               acceptance of the  resignation  shall not be necessary to make it
               effective. Upon the resignation,  retirement, death or removal of
               any Manager,  the Member who appointed such Manager will nominate
               and appoint a replacement Manager.

          7.7  Transactions  Between  Company and Managers.  The Members  hereby
               acknowledge that the Company may be required to borrow funds from
               any Manager or such Manager's  affiliates,  from time to time and
               at any time, in connection with the business of the Company. Each
               Manager is hereby  authorized,  without  further  approval by the
               Members,  to execute all documents and take all action  necessary
               to consummate any loans,  secured and/or  unsecured by the assets
               of the Company, to the Company by such Manager or an affiliate of
               such Manager, on terms and conditions that are acceptable to such
               Manager and  consistent  with the  provisions  of Section 3.4. In
               addition,  each Manager is hereby authorized to contract and deal
               with the Company,  or cause any person or entity  affiliated with
               such  Manager to  otherwise  contract  or deal with the  Company,
               provided  such  contracts  and  dealings   either  are  on  terms
               comparable to and competitive with those available to the Company
               from  others   dealing  at  arm's   length  or  are  approved  by
               disinterested  Members having more than 50% of the Sharing Ratios
               of all disinterested Members.

          7.8  Reimbursements.  Each  Manager  and each  officer  shall be reim-
               bursed by the  Company  for any  reasonable  out-of-pocket  costs
               incurred on behalf of the Company and a reasonable charge for the
               cost of general office and administrative  overhead  attributable
               to the performance of their duties to the Company,  together with
               reasonable  interest  that has accrued on such  amounts  from the
               date incurred until paid.

          7.9  Insurance.  The Company shall  maintain for the protection of the
               Company and all of its Members such  insurance as the  Management
               Committee,  in its  sole  discretion,  deems  necessary  for  the
               operations being conducted.

          7.10 Exculpation.  The Management  Committee and any officer appointed
               by the Management Committee shall not be liable to the Company or
               to any Member  for any act or failure to act,  nor for any errors
               of judgment, but only for willful misconduct or gross negligence.
               The Company shall  indemnify and hold harmless each member of the
               Management Committee, each officer and their agents and employees
               against and from any liability  other than such person's  willful
               misconduct or gross negligence. Any such indemnification shall be
               paid only from the assets of the Company, and no Member, Manager,
               officer or third party shall have  recourse  against the personal
               assets of any Member for such indemnification.

          7.11 Informal Action.  Any action required or permitted to be taken by
               the  Management  Committee  may be taken without a meeting if the
               action is evidenced by a written  consent  describing  the action
               taken, signed by each member of the Management Committee.  Action
               taken  under this  section is  effective  when all members of the
               Management Committee have signed the consent,  unless the consent
               specifies a different effective date.

          8.1  Participation.  A Member, in its capacity as a Member, shall take
               no part in the control,  management,  direction or oper- ation of
               the  affairs of the  Company  and shall have no power to bind the
               Company.

          8.2  Quorum.  A majority of the  outstanding  Voting  Interests,  rep-
               resented in person or by proxy,  shall be necessary to constitute
               a quorum at meetings of the Members.  Each of the Members  hereby
               consents and agrees that one or more Members may participate in a
               meeting  of the  Members  by means  of  conference  telephone  or
               similar communication  equipment by which all persons participat-
               ing in the  meeting  can hear one  another at the same time,  and
               such  participation  shall  constitute  presence in person at the
               meeting.  If a quorum is  present,  the  affirmative  vote of the
               majority of the Voting  Interests  represented at the meeting and
               entitled  to vote on the subject  matter  shall be the act of the
               Members,  unless a greater  number is required by the Act. In the
               absence of a quorum,  those  present  may adjourn the meeting for
               any period, but in no event shall such period exceed 60 days.

          8.3  Informal Action.  Any action required or permitted to be taken at

               action is evidenced by a written  consent  describing  the action
               taken, signed by each Member entitled to vote. Action taken under
               this section is effective when all Members  entitled to vote have
               signed the  consent,  unless the  consent  specifies  a different
               effective date.

          8.4  Meetings. Meetings of the Members for any purpose or purposes may
               be called by the  Management  Committee or by holders of not less
               than 10% of all Voting  Interests.  The place of meeting shall be

               authorized  attorney-in-fact.  Such proxy shall be filed with the
               Management  Committee  before or at the time of the  meeting.  No
               proxy  shall be valid  after  eleven  months from the date of its
               execution, unless otherwise provided in the proxy.

          8.7  Conduct of Meeting.  At each meeting of the  Members,  a Chairman
               for that particular meeting shall be elected.  The Chairman shall

                    Agreement that would be reasonably likely to have a material

                    relative  rights or obligations  under this Agreement or (z)

     For purposes of clauses (i) and (x) of this Section 8.9, any  alteration of
the Company's  Operating  Agreement  that would be reasonably  likely to have an
adverse financial impact to ADMI shall be deemed material.

     For purposes of this Section 8.9: (1) "Change in Ownership" means any sale,

reasonable  good faith judgment of the Management  Committee) in any transaction
or series of transactions (other than sales in the ordinary course of business),
and (B) any merger or consolidation to which the Company is a party,  except for
a merger  in  which  the  Company  is the  surviving  entity,  the  terms of the
outstanding  equity interests of all holders thereof are not changed and none of
the  outstanding  equity  interests are exchanged for cash,  securities or other
property,  and after giving effect to such merger,  the holders of the Company's
outstanding  equity  interests  possessing  the  voting  power  (under  ordinary
circumstances)  to  elect  a  majority  of the  Company's  Management  Committee

     Notwithstanding  any other  provision  of this  Operating  Agreement to the
contrary,  all rights of ADMI or its  successors  under this  Section  8.9 shall

equity securities in accordance with the rules and regulations of the Securities
Act of 1933, as amended, by means of an effective  registration  statement under
Form S-1 (or any successor form thereto).

                                    ARTICLE 9

                             ACCOUNTING AND REPORTING

          9.1  Books.  The  Management  Committee  shall  maintain  complete and
               accurate  books  of  account  at  the  registered  office  of the
               Company.  The Management  Committee  shall provide any Member any
               information  requested  relating to the  business of the Company.
               During  ordinary  business  hours any  Member  or its  authorized
               representative  shall  have  access  to all  books,  records  and
               materials regarding the Company and its activities.

               other  accounts as may be  necessary  or desirable to comply with
               the requirements of applicable laws and regulations.

          9.3  Transfers  During Year.  In order to avoid an interim  closing of
               the  Company's  books,  the share of  profits  and  losses  under
               Article 5 of a Member who  transfers  part or all of its interest
               in the  Company  during  the  Company's  accounting  year  may be
               determined  by taking  its pro rata  share of the  amount of such
               profits and losses for the year. The proration  shall be based on
               the  portion of the  Company's  accounting  year that has elapsed
               prior  to the  transfer  or may be  determined  under  any  other
               reasonable method; provided,  however, that any gain or loss from
               the sale of Company assets shall be allocated to the owner of the
               Company  interest  at the time of such sale.  The  balance of the
               profits  and  losses   attributable   to  the  Company   interest

               end of each fiscal year. As soon as practicable  thereafter,  the
               Management  Committee  shall  deliver  a  written  report to each
               Member,  which shall  include a statement of  receipts,  expendi-
               tures,  profits  and losses  for the year,  a  statement  of each
               Member's  capital  account and such  additional  statements  with
               respect to the status of the  Company's  assets and the distribu-
               tion of Company  funds as are  necessary  to advise  the  Members
               properly  about their  investment in the Company.  Prior to March
               15th of each year, the Members shall also be provided with a copy
               of the Company  federal  income tax return (Form 1065) to b filed

               by the requesting Member.

                                      ARTICLE 10

                              TRANSFERS; RIGHT OF FIRST REFUSAL

          10.1 Additional  Members.  Additional Members shall not be admitted to
               the  Company  without  the  written  consent of Members  having a
               Sharing Ratio of more than 50%.

          10.2 Offer to Other  Members.  If at any time any Member  proposes  to
               sell,  assign  or  otherwise  transfer  all  or any  part  of its
               interest in the Company, such Member ("Offeror") shall first make
               a written offer to sell such interest in the Company to the other
               Members on the same terms and subject to the same con- ditions as
               those on which the Offeror  proposes to transfer  the interest in
               the  Company.  Such offer  shall  state the name of the  proposed
               transferee  and all the  terms  and  conditions  of the  proposed
               transfer,   including  the  price  to  the  proposed  transferee.
               Notwithstanding  anything in this Section  10.2 to the  contrary,
               any Member  shall be free to  transfer  all or any portion of its
               interest  in the  Company  free of the  right  of  first  refusal
               provided  that such Member  transfers  its  interest to an entity
               controlled by the  transferor.  A transferee of a Member pursuant
               to the foregoing  sentence shall be subject to the right of first
               refusal contained in this Section 10.2.

          10.3 Acceptance of Offer. The other Members shall have the right for a
               period of 30 days after receipt of the offer from the Offeror, or
               such longer  period as may be required  under  Section  10.5,  to
               elect to purchase all of the interest in the Company offered.  In
               exercising their right to purchase,  the other Members may divide
               the interest offered in any manner to which they all agree and in
               the absence of agreement  the offered  interest  shall be divided
               among the Members in proportion to the relative Sharing Ratios of
               the Members who choose to partici- pate. To exercise their rights
               to purchase,  the other Members shall give written  notice to the
               Offeror.  Upon the  exercise of a right to purchase  and provided
               the right is exercised with respect to all of the interest in the
               Company offered, the purchase shall be closed and payment made on
               the same  terms  and  conditions  as those on which  the  Offeror
               proposes to transfer the interest in the Company.

          10.4 Failure  to Accept  Offer.  If the other  Members do not elect to
               purchase all of the interest in the Company offered,  the Offeror
               may  transfer  the offered  interest to the  proposed  transferee
               named in the offer to the Company.  However,  if that transfer is
               not made within 90 days after the end of the period  provided for
               in Section  10.3, a new offer shall be made to the other  Members
               and the  provisions of Sections  10.1,  10.2 and 10.3 shall again
               apply.

          10.5 Cash Equivalents. If the proposed offer under Section 10.2 is for
               consideration other than cash or cash plus deferred pay- ments of
               cash,  the  purchasing  Members  may pay the  present  value cash
               equivalent of such other  consideration or may pay using the same
               instrument as contemplated by the proposed offer. The Offeror and
               the  purchasing  Members  shall  attempt  to  agree  upon  a cash
               equivalent  of such other  consideration.  If they  cannot  agree
               within 20 days after the  beginning  of the 30-day  period  under
               Section  10.3,  any of such  Members  may, by five days'  written
               notice  to  the  others,  initiate  arbitration  proceedings  for
               determination of the cash equivalent without regard to income tax
               consequences  to the Offeror as a result of receiving cash rather
               than the other consideration. The purchasing Members may elect to
               purchase the interest at the determined cash equivalent by notice
               of  such  election  to the  Offeror  within  10  days  after  the
               arbitrator's decision.

          10.6 Direct and Indirect  Transfers.  For purposes of this  agreement,
               restrictions  upon the sale,  assignment  or other  transfer of a
               Member's  interest shall extend to any direct or indirect  trans-
               fer including,  without limitation,  an involuntary transfer such
               as a transfer  pursuant to a  foreclosure  sale or a transfer re-
               sulting by operation of law.

          10.7 Substitution of a Member.

               (a)  No  assignee,   legatee,   or  transferee  (by   conveyance,
                    operation of law or  otherwise)  of the whole or any portion
                    of a Member's  interest in the Company  shall have the right
                    to become a sub- stituted Member without the written consent
                    of Members other than the assignor,  legator or  transferor,
                    as the case may be, having a Sharing Ratio of more than 50%.
                    The granting or denial of a request for such written consent
                    shall be within the absolute  discretion  of each Member.  A
                    substituted  Member  shall  succeed  to all the  rights  and
                    interest of its  assignor in the  Company.  An assignee of a
                    Member that is not  admitted  as a Member  shall be entitled
                    only  to the  distributions  to  which  its  assignor  would
                    otherwise be entitled.

               (b)  If a Member shall be dissolved, merged or consolidated,  its
                    successor  in  interest  shall  have  the  same  rights  and
                    obligations  that such  Member  would have had if it had not
                    been  dissolved,  merged or  consolidated,  except  that the
                    successor shall not become a substituted  Member without the
                    prior written  consent of Members other than the predecessor
                    Member having a Sharing Ratio of more than 50%.

               (c)  As  conditions  to its  substitution  as a  Member  (a)  any
                    successor  of  a  Member  shall  execute  and  deliver  such
                    instruments,  in  form  and  substance  satisfactory  to the
                    Management Committee, as the Management Committee shall deem
                    necessary,  and (b) such successor  shall pay all reasonable
                    expenses in  connection  with its admission as a substituted
                    Member.

          10.8 Conditions  to  Transfer.  No  transfer  of any  interest  in the
               Company  otherwise   permitted  under  this  agreement  shall  be
               effective for any purpose  whatsoever  until the transferee shall
               have assumed the  transferor's  obligations  to the extent of the
               interest transferred and shall have agreed to be bound by all the
               terms  and  conditions  hereof,  by  written   instrument,   duly
               acknowledged,  in form and substance  reasonably  satisfactory to
               the Management Committee.

                                   ARTICLE 11

                                TAG-ALONG RIGHTS

     Subject  to the  provisions  of  Section  10,  in the  event a  Member  (an
"Offering  Member")  intends to transfer  all or any part of its interest in the
Company (also referred to as "Offered  Interests"),  such Offering  Member shall
notify each other  Member who has a Sharing  Ratio of more than 10%, in writing,
of such  proposed  transfer  and its terms and  conditions,  including,  without
limitation,  (i)  its  bona  fide  intention  to sell or  transfer  the  Offered
Interests,  (ii) the  number  and  class of Units  of  Offered  Interests  to be
transferred,  (iii) the price  and  terms,  if any,  for  which it  proposes  to
transfer  the Offered  Interests  and (iv) the name and address of the  proposed
purchaser or  transferee  and that such  purchaser or transferee is committed to
acquire  the  stated  number of Units on the stated  price and terms  ("Offering
Member Notice").  Within ten days of the date of such notice, each Member (other
than the  Offering  Member)  shall  notify the  Offering  Member in writing (the
"Co-Sale Notice") if it elects to participate in such transfer. Each Member that
so notifies the Offering  Member shall have the right to sell, at the same price
and on the same terms as the  Offering  Member,  an amount of Units equal to the
Units the third  party  proposes  to  purchase  multiplied  by a  fraction,  the
numerator  of which  shall be the number of Units  owned by such  Member and the
denominator  of  which  shall be the  aggregate  number  of  Units  owned by the
Offering  Member and each Member  exercising  its rights  under this Section 11.
Nothing  contained  in this  Section 11 shall in any way limit or  restrict  the
Offering  Member's  ability to amend,  modify or terminate any agreement  with a
third party with respect to any  transfer of its Units  pursuant to this Section
11, and the  Offering  Member shall have no liability to any Member with respect
to such  amendment,  modification  or  termination  unless any of the  foregoing
breaches this  Agreement.  If no Co-Sale  Notice is received  during the ten-day
period  referred  to above (or if the  Co-Sale  Notice does not cover all of the
Units proposed to be transferred), the Offering Member shall have the right, for
a sixty-day period after the expiration of the ten-day period referred to above,
to  transfer  the Units so  specified  in the  Offering  Member  Notice  (or the
remaining  Units) at the same or a lower price and on other terms and conditions
no more favorable than those stated in the Offering Member Notice.

                                     TERM

                                    ARTICLE 13

                              INITIAL PUBLIC OFFERING

          13.1 Conversion to Corporation.  If the Company decides to initiate an
               initial public offering,  and if that decision  requires that the
               Company  be  restructured  into  a  corporation  (the  "Resulting
               Corporation"),  then,  subject to the approval of the  Management
               Committee pursuant to Section7.1:

               (a)  the Resulting Corporation will be organized and incorporated
                    under the Laws of the State of Delaware;

               (b)  the Certificate of Incorporation and Bylaws of the Resulting
                    Corporation will include  standard and customary  provisions
                    as  will  then  be   applicable   to   public   corporations
                    incorporated  under the Laws of the State of  Delaware,  and
                    such  other   provisions  as  may  be  agreed  upon  by  the
                    Management Committee; and

               (c)  the  Members and the Company  will  negotiate  in good faith
                    with the intent of entering into a  shareholders'  agreement
                    that  will  contain  customary  provisions,  including  "tag
                    along" rights.

                                       ARTICLE 14

                                DISSOLUTION AND TERMINATION

          14.1 Final  Accounting.  In case of the dissolution of the Company,  a
               proper  accounting  shall be made as provided in Section 9.4 from
               the  date  of  the  last  previous  accounting  to  the  date  of
               dissolution.

          14.2 Liquidation.  Upon the dissolution of the Company, the Management
               Committee  shall select a person to act as  liquidator to wind up
               the Company.  The liquidator  shall have full power and authority
               to sell,  assign and encumber any or all of the Company's  assets
               and to wind up and  liquidate  the  affairs of the  Company in an
               orderly and  businesslike  manner.  All proceeds from liquidation
               shall be distributed in the following  order of priority:  (i) to
               the  payment  of debts and  liabilities  of the  Company  and the
               expenses of liquidation;  (ii) to the setting up of such reserves
               as  the  liquidator   may  reasonably   deem  necessary  for  any
               contingent  liabilities of the Company;  and (iii) to the Members
               in accordance with Article 4.

          14.3 Distribution  in Kind. If the liquidator  shall  determine that a
               Company asset should be distributed in kind, the liquidator shall
               obtain an  independent  appraisal of the fair market value of the
               asset as of a date  reasonably  close to the date of liquidation.
               Any unrealized  appreciation or depreciation with respect to such
               asset shall be allocated  among the Members (in  accordance  with
               the  provisions of Article 5 assuming that the asset was sold for
               the   appraised   value)  and  taken  into  consid-   eration  in
               determining the balance in the Member' capital accounts as of the
               date of liquidation.  Distribution of any such asset in kind to a
               Member shall be considered a  distribution  of an amount equal to
               the asset's fair market value for purposes of Section  14.2.  The
               liquidator, in its sole discretion, may distribute any percentage
               of any asset in kind to a Member eve if such  percentage  exceeds
               the  percentage  in which the Member shares in  distributions  as
               long as the sum of the  cash  and  fair  market  value of all the
               assets  distributed  to each  Member  equals  the  amount  of the
               distribution to which each Member is entitled.

          14.4 Waiver of Right to Court Decree of Dissolution. The Members agree
               that  irreparable  damage  would  be done to the  Company  if any
               Member  brought  an  action  in court to  dissolve  the  Company.
               Accordingly,  each of the Members  accepts the  provisions of thi
               Agreement as its sole  entitlement on termination of the Member's
               membership  in  the  Company.   Each  Member  hereby  waives  and
               renounces all rights to seek a court decree of  dissolution or to
               seek the appointment by a court of a liquidator for the Company.

          14.5 Articles of  Dissolution.  Upon the  completion  of the distribu-
               tion of  Company  assets as  provided  in this  Article  14,  the
               Company shall be  terminated  and the person acting as liquidator
               shall  file  articles  of  dissolution  and shall take such other
               actions as may be necessary to terminate the Company.

                                      ARTICLE 15

                                        NOTICES

          15.1 Method of Notices.  All notices  required  or  permitted  by this
               agreement shall be in writing and shall be hand delivered or sent
               by registered or certified mail,  postage  prepaid,  and shall be
               effective  when  received or, if mailed,  on the date se forth on
               the receipt of registered or certified  mail, or on the fifth day
               after mailing, whichever is earlier.

          15.2 Computation  of Time.  In computing any period of time under this
               agreement,  the day of the act,  event or default  from which the
               designated period of time begins to run shall not be included The
               last day of the period so computed  shall be included,  unless it
               is a Saturday, Sunday or legal holiday, in which event the period
               shall run until the end of the next day which is not a  Saturday,
               Sunday or legal holiday.

                                     ARTICLE 16

                             INVESTMENT REPRESENTATIONS

          16.1 Investment Purpose. In acquiring an interest in the Company, each
               Member  represents  and  warrants  to  the  Company  that  it  is
               acquiring  such interest for its own account for  investment  and
               not  with a  view  to  its  sale  or  distribution.  Each  Member
               recognizes  that  investments  such as those  contemplated by the
               Company are  speculative and involve  substantial  risk. Each Me-
               ber further  represents and warrants that it has not received any
               guaranty or  representation  upon which it has relied  concerning
               the  possibility  or probability of profit or loss as a result of
               its acquisition of an interest in the Company.

          16.2 Investment  Restriction.  Each Member  recognizes  that:  (a) its
               Units have not been registered  under the Securities Act of 1933,
               as amended,  in reliance  upon an exemption  from such  registra-
               tion, (b) a Member may not sell, offer for sale, transfer, pledge
               or hypothecate  all or any part of its interest in the Company in
               the absence of an effective  registration statement covering such
               interest  under the  Securities  Act of 1933, as amended,  unless
               such sale,  offer of sale,  transfer,  pledge or hypothecation is
               exempt from  registration  under the  Securities  Act of 1933, as
               amended,  (c) the  Company  has no  obligation  to  register  any
               Member's  interest  for sale,  or to assist in estab-  lishing an
               exemption  from  registration  for any proposed sale, and (d) the
               restrictions  on transfer may severely  affect the liquidity of a
               Member's investment.

                                      ARTICLE 17

                                   GENERAL PROVISIONS

          17.1 Entire  Agreement.  This  Agreement  embodies  the entire  under-
               standing and agreement  among the parties  concerning the Company

               Agreement,  this  Agreement may not be amended nor may any rights
               hereunder be waived except by an instrument in writing  signed by
               Members having a Sharing Ratio of more than 50% in the aggregate.

          17.3 Applicable  Law. This Agreement  shall be construed in accordance
               with and governed by the laws of the State of Delaware.

          17.4 Pronouns.  References  to a  Member,  including  by use of a pro-
               noun, shall be deemed to include masculine,  feminine,  singular,
               plural,  individuals,  partnerships,  corporations or other legal
               entities where applicable.

               counterparts each of which shall be considered an original.
