                            Schedule 3.1           $5.0 million         50.0%

are attached hereto as Exhibits B(1) and B(2), respectively.

         3.2      Other Matters.

         (a) Except as  otherwise  provided in this  Agreement,  no Member shall
demand or receive a return on or of its Capital  Contributions  or withdraw from
the Company without the consent of all Members. Under circumstances  requiring a
return of any Capital Contributions, no Member has the right to receive Property
other than cash except as may be specifically provided herein.

         (b) No Member  shall  receive  any  interest,  salary or  drawing  with
respect to its  Capital  Contributions  or its Capital  Account or for  services
rendered on behalf of the Company,  or  otherwise,  in its capacity as a Member,
except as  otherwise  provided in this  Agreement  or approved by the  Governing

         (e) Each of Magellan and New Crescent  will  contribute  an  additional
$2.5  million to the capital of the Company  within five (5) days after  Closing
("Additional Capital  Contribution").  Additionally,  on the Effective Date, (i)
each of  Magellan  and New  Crescent  shall  agree to loan the  Company up to an
aggregate  of  $17.5  million  each  (a  "Member   Commitment"),   which  Member
Commitments  shall terminate on the fifth anniversary of the Effective Date, and
(ii) the Company shall execute two notes (the "Member  Notes"),  one to Magellan
and one to New Crescent, as security for each such Member Commitment.  Magellan,

to draw down a portion of the Member  Commitments  by providing  written  notice
specifying  the total amount to be drawn,  and the date (which shall not be less
than thirty  Business Days after the date of such notice)of such draw. Each such
draw (a  "Member  Advance")  shall be funded  50% by  Magellan  from its  Member
Commitment  and 50% by New  Crescent  from its Member  Commitment.  Each  Member
Advance  shall bear  interest at a rate of 10% per annum and have a term of five

Advance is made). Notwithstanding

anything  to the  contrary,  neither  Magellan  nor OpCo shall have the right to
require a Member Advance from New Crescent unless Magellan is required to make a
Member  Advance in the same amount as that required for New Crescent.  Until the
Company secures a Senior Facility in an amount of at least $55 million supported
by the Company without a guarantee from New Crescent,  payments under any Member
Advances  which are  required to be made to Magellan  shall be  subordinated  to
payments  under  any  Member  Advances  which  are  required  to be  made to New
Crescent. If either Magellan or New Crescent shall fail to make a Member Advance
pursuant to this paragraph  within  fifteen  Business Days of the date specified
above, with respect to the Additional  Capital  Contribution,  or in such notice
from  Magellan  requiring a Member  Advance and such  failure  continues  for an
additional  ten  Business  Days after  notice from the other  Member,  then such
defaulting  Member shall be deemed to have sold its  membership  interest in the
Company to the other Member upon delivery of payment by such other Member to the
defaulting  Member of the sum of $100.  Except for the  foregoing,  the  Members
shall not be required to make any additional  capital  contributions or loans to
the Company.  Such obligation to make Additional Capital  Contributions or loans
is solely for the benefit of the Members,  and no Person  shall be  considered a
third-party beneficiary of such obligation. The Company shall use all Additional
Capital Contributions and Member Advances for the benefit of the Company in such
manner as Magellan, in its sole discretion, directs.

         (f)      The Directors shall not have any personal liability for the 
repayment of any Capital Contributions of any Member.

         (g) Notwithstanding any other provision of this Agreement,  each Member
agrees to approve such amendments to this Agreement as are necessary to allocate
up to 10% of the Percentage Interests in the Company,  equally from each Member,
for future incentive payments to management.

                                   SECTION 6.

                                   ALLOCATIONS

         6.1      Profits.

         After giving  effect to the special  allocations  set forth in Sections
6.3 and 6.4,  Profits for any Allocation  Year shall be allocated to the Members
in proportion to their Percentage Interests.






                                                                             20

         6.2      Losses.

         After giving  effect to the special  allocations  set forth in Sections
6.3 and 6.4 and subject to Section 6.5,  Losses for any Allocation Year shall be
allocated to the Members in proportion to their Percentage Interests.

         6.3      Special Allocations.

         The following special allocations shall be made in the following order:

         (a) Minimum Gain Charge Back.  Except as otherwise  provided in Section
1.704-2(f)  of the  Regulations,  notwithstanding  any other  provision  of this
Section  6, if there is a net  decrease  in  Company  Minimum  Gain  during  any
Allocation  Year,  each Member  shall be  specially  allocated  items of Company
income  and  gain  for such  Allocation  Year  (and,  if  necessary,  subsequent
Allocation  Years) in an amount equal to such Member's share of the net decrease
in Company  Minimum Gain, as determined in accordance with  Regulations  Section
1.704-2(g).  Allocations  pursuant  to the  previous  sentence  shall be made in
proportion  to the  respective  amounts  required to be allocated to each Member
pursuant thereto. The items to be so allocated shall be determined in accordance
with Sections  1.704-2(f)(6) and 1.704-2(j)(2) of the Regulations.  This Section
6.3(a) is intended to comply with the minimum  gain charge back  requirement  in
Section  1.704-2(f) of the  Regulations  and shall be  interpreted  consistently
therewith.

         (b) Member  Minimum Gain Charge Back.  Except as otherwise  provided in
Section 1.704-2(i)(4) of the Regulations, notwithstanding any other provision of
this  Section 6, if there is a net decrease in Member  Nonrecourse  Debt Minimum
Gain attributable to a Member  Nonrecourse Debt during any Allocation Year, each
Member who has a share of the Member  Nonrecourse Debt Minimum Gain attributable
to  such  Member  Nonrecourse  Debt,   determined  in  accordance  with  Section
1.704-2(i)(5) of the Regulations,  shall be specially allocated items of Company
income  and  gain  for such  Allocation  Year  (and,  if  necessary,  subsequent
Allocation  Years) in an amount equal to such Member's share of the net decrease
in Member  Nonrecourse Debt,  determined in accordance with Regulations  Section
1.704-2(i) (4).  Allocations  pursuant to the previous sentence shall be made in
proportion  to the  respective  amounts  required to be allocated to each Member
pursuant thereto. The items to be so allocated shall be determined in accordance
with Sections  1.704-2(i)(4) and 1.704-2(j)(2) of the Regulations.  This Section
6.3(b) is intended to comply with the minimum  gain charge back  requirement  in
Section  1.704-2(i)(4) of the Regulations and shall be interpreted  consistently
therewith.

         (c)  Qualified  Income  Offset.  In the event any  Member  unexpectedly
receives any adjustments,  allocations,  or distributions  described in Sections
1.704-1(b)(2)(ii)(d)(4),  1.704-1(b)(2)(ii)(d)(5), or 1.704-1(b)(2)(ii)(d)(6) of
the Regulations,  items of Company income and gain shall be specially  allocated
to such Member in an amount and manner  sufficient to  eliminate,  to the extent
required by the Regulations,  the Adjusted Capital Account Deficit of the Member
as quickly as possible;  provided  that an  allocation  pursuant to this Section
6.3(c) shall





                                                                             21

be made only if and to the extent that the Member would have an Adjusted Capital
Account Deficit after all other allocations  provided for in Section 6 have been
tentatively made as if this Section 6.3(c) were not in the Agreement.

         (d) Gross  Income  Allocation.  In the event any  Member  has a deficit
Capital  Account at the end of any Allocation Year which is in excess of the sum
of the amount such Member is deemed to be obligated  to restore  pursuant to the
penultimate  sentences of Regulations Sections  1.704-2(g)(1) and 1.704-2(i)(5),
each such Member shall be specially  allocated  items of Company income and gain
in the amount of such excess as quickly as possible, provided that an allocation
pursuant  to this  Section  6.3(d)  shall be made only if and to the extent that
such Member would have a deficit  Capital Account in excess of such amount after
all  other  allocations  provided  for in this  Section  6 have  been made as if
Section 6.3(c) and this Section 6.3(d) were not in the Agreement.

         (e) Nonrecourse Deductions.  Nonrecourse Deductions for any Allocation 
Year shall be  specially  allocated  to  the  Members  in  proportion  to their
respective Percentage Interests.

         (f) Member Nonrecourse  Deductions.  Any Member Nonrecourse  Deductions
for any Allocation Year shall be specially allocated to the Member who bears the
economic risk of loss with respect to the Member  Nonrecourse Debt to which such
Member  Nonrecourse  Deductions are  attributable in accordance with Regulations
Section 1.704-2(i)(1).

         (g)  Section  754  Adjustments.  To the  extent  an  adjustment  to the
adjusted tax basis of any Company asset, pursuant to Code Section 734(b) or Code
Section    743(b)    is    required,    pursuant    to    Regulations    Section
1.704-1(b)(2)(iv)(m)(2) or 1.704-1(b)(2)(iv)(m)(4),  to be taken into account in
determining  Capital  Accounts  as the result of a  distribution  to a Member in
complete  liquidation  of such Member's  interest in the Company,  the amount of
such adjustment to Capital  Accounts shall be treated as an item of gain (if the
adjustment  increases  the  basis  of the  asset)  or loss  (if  the  adjustment
decreases such basis) and such gain or loss shall be specially  allocated to the
Members  in  accordance  with  their  interests  in the  Company  in  the  event
Regulations  Section  1.704-1(b)(2)(iv)(m)(2)  applies, or to the Member to whom
such    distribution    was   made   in   the    event    Regulations    Section
1.704-1(b)(2)(iv)(m)(4) applies.

         (h) Allocations  Relating to Taxable Issuance of Company Interest.  Any
income,  gain, loss or deduction  realized as a direct or indirect result of the
issuance of Interests by the Company to a Member (the "Issuance Items") shall be
allocated among the Members so that, to the extent  possible,  the net amount of
such Issuance Items, together with all other allocations under this Agreement to
each Member,  shall be equal to the net amount that would have been allocated to
each such Member if the Issuance Items had not been realized.






                                                                             22

         6.4      Curative Allocations.

         The  allocations  set  forth  in  Sections  6.3(a)  to (g) and 6.5 (the
"Regulatory  Allocations")  are intended to comply with certain  requirements of
the  Regulations.  It is the intent of the Members that, to the extent possible,
all  Regulatory  Allocations  shall  be  offset  either  with  other  Regulatory
Allocations or with special allocations of other items of Company income,  gain,
loss or deduction pursuant to this Section 6.4.  Therefore,  notwithstanding any
other provision of this Section 6 (other than the Regulatory  Allocations),  the
Governing  Board  shall  make such  offsetting  special  allocations  of Company
income, gain, loss or deduction in whatever manner it determines  appropriate so
that, after such offsetting  allocations are made, each Member's Capital Account
balance is, to the extent  possible,  equal to the Capital  Account balance such
Member  would  have  had if the  Regulatory  Allocations  were  not  part of the
Agreement and all Company items were allocated pursuant to Sections 6.1 and 6.2;
provided,  however,  that the Governing Board shall not make offsetting  special
allocations if and to the extent that such Regulatory Allocations were or likely
will be offset with Regulatory Allocations in prior or future years.

         6.5      Loss Limitation.

         Losses  allocated  pursuant to Section 6.2 hereof  shall not exceed the
maximum  amount of Losses that can be  allocated  without  causing any Member to
have an Adjusted  Capital Account Deficit at the end of any Allocation  Year. In
the event some but not all of the Members  would have Adjusted  Capital  Account
Deficits as a consequence  of an  allocation  of Losses  pursuant to Section 6.2
hereof,  the  limitation  set forth in this  Section  6.5 shall be  applied on a
Member by Member  basis and  Losses not  allocable  to any Member as a result of
such  limitation  shall be allocated to the other Members in accordance with the
positive  balances in such  Members'  Capital  Accounts  so as to  allocate  the
maximum permissible Losses to each Member under Section 1.704- 1(b)(2)(ii)(d) of
the Regulations.

         6.6      Other Allocation Rules.

         (a) For purposes of determining the Profits, Losses, or any other items
allocable  to any  period,  Profits,  Losses,  and any such other items shall be
determined on a daily,  monthly,  or other basis, as determined by the Governing
Board,  using any permissible  method under Code Section 706 and the Regulations
thereunder.

         (b) The  Members  are  aware  of the  income  tax  consequences  of the
allocations  made  by  this  Section  6 and  hereby  agree  to be  bound  by the
provisions  of this  Section 6 in reporting  their shares of Company  income and
loss for income tax purposes.

         (c) For purposes of making all  allocations  pursuant to this Section 6
for any Allocation Year, cash distributed within thirty (30) days after the last
day of such Allocation Year shall be treated as having been  distributed on such
last day pursuant to Section 7.1 hereof.






                                                                             23

         (d) Solely for purposes of determining a Member's  proportionate  share
of the "excess  nonrecourse  liabilities"  of the Company  within the meaning of
Regulations  Section  1.752-3(a)(3),  the Members'  interests in Company profits
shall be in proportion to their Percentage Interests.

         (e)  To  the  extent   permitted  by  Section   1.704-2(h)(3)   of  the
Regulations,  the Governing Board shall endeavor to treat  distributions of cash
as having been made from the  proceeds of a  Nonrecourse  Liability  or a Member
Nonrecourse  Debt only to the  extent  that such  distributions  would  cause or
increase an Adjusted Capital Account Deficit for any Member.

         6.7      Tax Allocations:  Code Section 704(c).

         In accordance with Code Section 704(c) and the Regulations  thereunder,
income,  gain,  loss, and deduction with respect to any Property  contributed to
the capital of the Company shall,  solely for tax purposes,  be allocated  among
the Members so as to take account of any variation between the adjusted basis of
such  Property to the Company for federal  income tax  purposes  and its initial
Gross Asset Value  (computed in  accordance  with the  definition of Gross Asset
Value). Any such variation with respect to the Contributed Assets (as defined in
the  OpCo  Contribution  Agreement)  shall  be  calculated  using  the  remedial
allocation method described in Regulation Section 1.704-3(d).

         In the event the Gross  Asset  Value of any  Company  asset is adjusted
pursuant to subparagraph (b) of the definition of Gross Asset Value,  subsequent
allocations  of income,  gain,  loss,  and deduction  with respect to such asset
shall take account of any variation between the adjusted basis of such asset for
federal  income tax  purposes  and its Gross  Asset  Value in the same manner as
under Code Section 704(c) and the Regulations thereunder.

         Any elections or other decisions  relating to such allocations shall be
made by a  supermajority  (of at least 80%) of the Governing Board in any manner
that   reasonably   reflects  the  purpose  and  intention  of  this  Agreement.
Allocations  pursuant to this  Section  6.7 are solely for  purposes of federal,
state, and local taxes and shall not affect, or in any way be taken into account
in computing,  any Member's Capital Account or share of Profits,  Losses,  other
items, or distributions pursuant to any provision of this Agreement.

                                   SECTION 7.

                                  DISTRIBUTIONS

         7.1  Distribution of Available Cash.  Subject to the provisions of this
Section 7, the Company's  available cash shall be distributed to the Members, in
such amounts and only at such times as  determined by the  Governing  Board,  in
proportion to their respective Percentage Interests.  In no event shall any cash
distribution  be made to the  Members  unless  and  until  rent  due  under  the
Facilities  Lease and fees due under the  Franchise  Agreement are fully paid in
the year of any distribution.






                                                                             24

         7.2 Amounts  Withheld.  Each Member  hereby  authorizes  the Company to
withhold  from or pay on behalf of or with  respect to such Member any amount of
federal, state, local, or foreign taxes that the Governing Board determines that
the  Company  is  required  to  withhold  or pay  with  respect  to  any  amount
distributable or allocable to such Member pursuant to this Agreement, including,
without  limitation,  any taxes  required  to be withheld or paid by the Company
pursuant to Sections 1441,  1442,  1445, or 1446 of the Code. Any amount paid on
behalf of or with respect to a Member shall  constitute a loan by the Company to
such Member,  which loan shall be repaid by such Member within fifteen (15) days
after notice from the Governing  Board that such payment must be made unless (i)
the Company withholds such payment from a distribution  which would otherwise be
made to the Member,  or (ii) the  Governing  Board  determines,  in its sole and
absolute  discretion,  that such payment may be satisfied  out of the  available
funds of the Company which would,  but for such payment,  be  distributed to the
Member. Any amounts withheld pursuant to the foregoing clauses (i) or (ii) shall
be treated  as having  been  distributed  to such  Member.  Each  Member  hereby
unconditionally and irrevocably grants to the Company a security interest (which
shall be  subordinate  to any  pledge  granted  to a  financial  institution  as
contemplated  by Section  12.2) in such Member's  Percentage  Interest to secure
such Member's  obligation to pay to the Company any amounts  required to be paid
pursuant  to this  Section  7.2.  In the  event  that a Member  fails to pay any
amounts owed to the Company pursuant to this Section 7.2 when due, the Governing
Board may, in its sole and absolute discretion, elect to make the payment to the
Company on behalf of such  defaulting  Member and, until repayment of such loan,
shall succeed to all rights and remedies of the Company  against such defaulting
Member (including, without limitation, the right to receive distributions).  Any
amounts  payable by a Member  hereunder  shall bear interest at the base rate on
corporate  loans at large  United  States  money  center  commercial  banks,  as
published  from time to time in the Wall Street  Journal,  plus four  percentage
points (but not higher than the maximum lawful rate) from the date such





                                                                             25

amount is due (i.e.,  fifteen (15) days after  demand) until such amount is paid
in full.  Each Member  shall take such  actions as the Company or the  Governing
Board shall request in order to perfect or enforce the security interest created
hereunder.


                                   SECTION 8.

                                   MANAGEMENT

         8.1      Directors; Governing Board.

         (a) The  management of the Company  shall be vested in the  four-member
Governing Board (the "Governing Board") designated by the Members as provided in
Sections 8.1(c) and (d) hereof.

         (b)  The  number  of  Persons,  each  of whom  shall  be an  individual
(hereinafter  referred to as  "Directors")  on the Governing Board shall be four
(4) unless  otherwise  provided  herein.  Each Director shall be a "Manager," as
defined in the Act, who shall have  authority to act on behalf of the Company as
set forth herein.  The Directors shall serve without  compensation  but shall be
entitled  to  reimbursement  for their  out-of-pocket  costs for their  services
hereunder.

         (c)   Simultaneously   with  the  execution  hereof,   Magellan  hereby
designates  the  individuals  set forth in Items  (1)  through  (2) as  Magellan
Directors and New Crescent hereby  designates the individuals set forth in Items
(3)  through (4) as  Crescent  Directors,  such that the name and address of the
Directors  who shall  serve until their  respective  successors  shall have been
designated and qualified are as follows:


           Name                 Business Address and Telephone Number
- -----------------------    -----------------------------------------------

1.  [Magellan Director]
2.  [ " ]
3.  [Crescent Director]
4.  [ " ]

         (d) No vote of the Members  shall be required to  designate  Directors.
Rather,  Magellan shall have the right to designate two (2) Magellan  Directors,
and New Crescent shall have the right to designate two (2) Crescent Directors. A
Director  shall remain in office until  removed by the Member  designating  such
Director.  With respect to any  Director  other than the initial  Directors  set
forth in Section  8.1(c) hereof,  Magellan or New Crescent,  as the case may be,
shall





                                                                             26

designate  such  Director by  delivering  to the Company  the  Member's  written
statement  designating such Director and setting forth such Director's  business
address and telephone number.

         (e) A  Director  may be removed  at any time,  with or  without  cause,
solely by the Member  originally  designating  such  Director.  Removal shall be
accomplished by delivery of written notice to the Company demanding such removal
and designating the Person who shall fill the position of the removed Director.

         (f) In the event any  Director  dies or is unwilling or unable to serve
as such or is removed from office by the Member that  designated  such Director,
the appropriate Member shall promptly designate a successor to such Director.  A
Director  chosen to fill a  vacancy  shall be  designated  by the  Member  whose
previously designated Director shall have been removed or shall have resigned.

         (g) Each Director shall have one (1) vote. Except as otherwise provided
in Sections 8.2 and 8.3 hereof, the Governing Board shall act by the affirmative
vote of a majority of the total number of Directors on the  Governing  Board.  A
Director may authorize any other Director to act for him by proxy on all matters
in which a Director is entitled to participate,  including waiving notice of any
meeting, or voting or participating at a meeting.  Every proxy must be signed by
the  Director  or its  attorney-in-fact.  No  proxy  shall be  valid  after  the
expiration of eleven (11) months from the date thereof unless otherwise provided
in the proxy.  Every proxy shall be  revocable  at the  pleasure of the Director
executing it.

         (h) The Governing  Board shall have the power to delegate  authority to
such committees of Directors, officers, employees, agents and representatives of
the  Company as it may from time to time deem  appropriate.  Any  delegation  of
authority  to take any action  must be  approved  in the same manner as would be
required for the Governing Board to approve such action directly.

         (i) A Director shall not be liable under a judgment, decree or order of
court,  or in any other  manner,  for a debt,  obligation  or  liability  of the
Company.

         8.2      Major Decisions.

         Notwithstanding  the other  provisions of this Section 8, no officer or
employee of the Company  shall have any authority to cause or permit the Company
or any of its subsidiaries or Affiliates to take any of the following actions or
make any of the following decisions (each, a "Major Decision") without the prior
express  action and approval of at least eighty  percent  (80%) of the Governing
Board:

                  (1) any sale,  lease,  transfer  or other  disposition  of any
         asset of the Company or any  subsidiary  of the Company in an amount in
         excess of $50,000,  to the extent  such sale,  lease,  transfer,  other
         disposition  or  granting  of  security  interest  was  not  previously
         approved in the Annual Budget for the then current Fiscal Year;





                                                                             27

                  (2) the  acquisition  from any Person of any stock or interest
         in any  corporation,  company,  partnership,  association,  business or
         business   division,   whether  by  stock  purchase,   asset  purchase,
         contribution, merger or other business combination or joint venture, or
         otherwise  causing or permitting the Company to be a party to a merger,
         transfer  of assets,  consolidation  or  reorganization  with any other
         Person,  provided,  however,  that the Company  shall have the right to
         invest in  short-term,  highly liquid  investments  (which mature in no
         more than 60 days)  with  appropriate  safety of  principal  including,
         without limitation, U.S. Government securities;

                  (3)  the  filing  of  a  voluntary  petition  for  bankruptcy,
         insolvency or the making of any assignment for the benefit of creditors
         by or of the  Company or any other  action  which  would  constitute  a
         Bankruptcy of the Company, or the substantial equivalent thereof;

                  (4)      the election to dissolve and terminate the Company;

         (c) If the  Governing  Board is unable to agree on the  Annual  Budget,
then  until  such time as the  Governing  Board is able to adopt and  approve an
Annual  Budget,  the Annual  Budget  shall  consist of the items in the proposed
Annual  Budget  which are not in dispute  and,  with  respect to those  items in
dispute, the items and amounts in the prior year's Annual Budget shall be deemed
to constitute  the approved  amounts in the Annual  Budget,  as the case may be;
provided,  however,  that the amount budgeted for  acquisitions or financing for
the  then-current  Fiscal  Year shall be the amount that the parties are able to
agree upon or, if they are unable to agree, then these amounts shall be zero for
the  then-current   Fiscal  Year  unless   necessary  for  ongoing   operations.
Notwithstanding anything contained herein to the contrary, to the extent that an
expenditure is required to be made pursuant to a legally  binding  obligation of
the Company which has been  previously  approved by the  Governing  Board or the
Members (or not required to be approved  pursuant to this  Agreement)  or to the
extent  that any such  expenditure  is beyond  the  Company's  control,  such as

date,  place  (which  shall be at the  principal  office of the  Company  unless
otherwise  agreed to by all Directors) or other means of conducting such meeting
and (ii) the purpose of the meeting to be so held.  No actions  other than those
specified  in  the  notice  may be  considered  at any  special  meeting  unless
unanimously  approved by the  Directors.  Any  Director  may waive notice of any
meeting in  writing  before,  at or after  such  meeting.  The  attendance  of a
Director  at a meeting  shall  constitute  a waiver  of notice of such  meeting,
except when a Director attends a meeting for the express purpose of objecting to
the transaction of any business because the meeting was not properly called.

be  taken  at  a  meeting  held  by  means  of  telephone  conference  or  other
communications  equipment  by means of which all  persons  participating  in the
meeting can hear each other.  Participation  in such a meeting shall  constitute
presence in person at such meeting.

         (e)  Notwithstanding  anything to the contrary in this Section 8.4, the
Governing  Board may take  without a meeting any action that may be taken by the
Governing Board under this Agreement if such action is approved by the unanimous

                                 ROLE OF MEMBERS

         9.1      Rights or Powers.

         The  Members  shall  not  have any  right or power to take  part in the
management  or control of the Company or its  Business and affairs or to act for
or bind the  Company  in any way,  except  the  Members  have all the rights and
powers  specifically  set  forth  in  this  Agreement  and,  to the  extent  not
inconsistent with this Agreement, in the Act. A Member, any Affiliate thereof or
an  employee,  stockholder,  agent,  director  or  officer  of a  Member  or any
Affiliate  thereof,  may also be an  employee  or be retained as an agent of the
Company. The existence of these relationships and acting in such capacities will
not result in the Member's  being deemed to be  participating  in the control of
the  Business of the Company or  otherwise  affect the limited  liability of the
Member.  A Member  shall  not,  in its  capacity  as a Member,  take part in the
operation,  management  or  control  of the  Company's  business,  transact  any
business  in the  Company's  name or have  the  power to sign  documents  for or
otherwise bind the Company.

         9.3      Meetings of the Members.

given to all Members not less than seven (7) Business  Days nor more than thirty
(30) days prior to the date of such  meeting.  Members  may vote in  person,  by
proxy or by  telephone  at such  meeting  and may waive  advance  notice of such

Percentage  Interests in the Company  constitute a quorum for the transaction of
business at a meeting of the Members. Whenever the vote or consent of Members is
permitted or required under the Agreement,  such vote or consent may be given at
a  meeting  of the  Members  or may be given in  accordance  with the  procedure

proxy must be signed by the Member or its  attorney-in-fact.  No proxy  shall be
valid after the  expiration  of eleven (11) months from the date thereof  unless
otherwise  provided in the proxy. Every proxy shall be revocable at the pleasure
of the Member executing it.

         (c)  Notwithstanding  this Section 9.3, the Company may take any action
contemplated  under this  Agreement  as approved by the consent of the  Members,
such consent to be provided in writing,  or by telephone or  facsimile,  if such
telephone  conversation  or  facsimile  is followed by a written  summary of the
telephone  conversation  or  facsimile   communication  sent  by  registered  or
certified mail,  postage and charges prepaid,  addressed as described in Section
16.2  hereof,  or to such  other  address  as such  Person may from time to time
specify by notice to the Members and Directors.

         9.4      Required Member Consents.

         Notwithstanding  any other  provision of this Operating  Agreement,  no

change in any item of income,  gain,  loss,  deduction,  or credit or Profits or
Losses as previously  reported or in the  allocation of such items of Profits or
Losses. The Tax Matters Member shall be responsible for preparing and filing, or
causing to be prepared and filed, all federal,  state, and local tax returns and
shall  submit all  federal,  state,  and local  income tax returns and any other
material federal, state, and local tax returns to the Governing Board for review

the Company solely by reason of being a Member of the Company. A Member shall be
liable only to make the  Capital  Contributions  described  in Section 3, on the

limitation:

hereof,  a Member  may at any time  Transfer  all (but not less than all) of its
Interest to (i) a wholly  owned  subsidiary  of that Member,  provided  that the
transferee  subsidiary  agrees  to  retransfer  all of  such  Interest  to  such
transferring  Member if such transferee  subsidiary  ceases to be a wholly owned
subsidiary of the transferring  Member,  (ii) the transferor's  administrator or
trustee to whom such Interest is transferred  involuntarily by operation of law,
(iii) any transferee if the transfer is approved by all Members which own twenty
percent (20%) or more of the  outstanding  Percentage  Interests,  in their sole
discretion,  (iv) in the case of New  Crescent,  to a single  transferee if such
transfer is necessary  for Crescent Real Estate  Equities  Company  ("CEI"),  as
currently  operated  or as  operated or proposed to be operated in the future to
avoid jeopardizing its status as a real estate investment trust (a "REIT") under
the Code,  provided that prior to any transfer made by New Crescent  pursuant to
this clause (iv), New Crescent shall provide  Magellan with a written opinion of
counsel that such transfer is necessary to avoid  jeopardizing the qualification

receiving  notice from New  Crescent of its intent to transfer  pursuant to this
clause (iv) and a written opinion of counsel referred to above,  whether it will
exercise such rights,  and, if it elects to exercise such right,  shall complete
the purchase of such Interest  within 25 days after the original notice from New
Crescent  (subject to the right of Magellan to extend the date for completion of
the  purchase  for up to an  additional  20  days if  necessary  to  obtain  any
regulatory  approvals  required in connection  therewith)  and (v) to any Person
upon  compliance  with the  provisions of Section 12.8 hereof (any such Transfer
being  referred  to in  this  Agreement  shall  be a  "Permitted  Transfer").  A
permitted  transferee  or other  transferee  shall be admitted as a  substituted
Member of the Company in accordance with Section 12.6.

         In addition,  a Member may also transfer its  Interest,  except for any
voting rights associated with such Interest (other than voting rights in respect
of the matters  listed in Section 9.4) and the right to  designate  Directors on
the Governing Board (each of which rights will remain with such





                                                                             43

immediately  prior to the creation of such  pledge,  is not an Affiliate of such
Member,  to secure bona fide arms' length  recourse  indebtedness of such Member
and/or its subsidiaries if the pledgee thereof agrees (i) to provide the Company
with all  notices  of  foreclosure  by such  pledgee  and (ii) in the event such
pledgee  becomes  a  Member,  to be bound by the  provisions  of this  Agreement
applicable to its  transferor,  it being  understood that both (x) the making of
such pledge and (y) such financial institution's becoming a Member as the result
of foreclosure on such pledge in full or partial satisfaction of all or any part
of the indebtedness  secured thereby or otherwise as a result of the exercise by
it of its rights and  remedies  with  respect  thereto  shall each  constitute a
Permitted  Transfer and such financial  institution  shall be a "Member" for the
purposes of this Agreement,  subject to the limitations described above. If such
financial  institution  transfers any portion of a Member's Interest pursuant to
the terms of this Agreement,  including pursuant to Section 15.3 in the event of
an Unresolved  Deadlock,  then,  upon the  consummation  of such  transfer,  the
transferee  shall  have  all of the  rights  associated  with  such  transferred
Interest  prior to its transfer to such  financial  institution  (including  all
voting rights and the right to designate  Directors  related to such transferred
Interest or a portion thereof),  and the Member which initially  transferred its
Interest  to such  financial  institution  shall  have no  more  rights  in such
Interest (to the extent transferred by the financial institution).

         12.3     Conditions to Permitted Transfers.

         A Transfer  shall not be treated as a Permitted  Transfer under Section
12.2 hereof unless and until the following conditions are satisfied:

         (a) Except in the case of a Transfer involuntarily by operation of law,
the  transferor  and  transferee  shall  execute and deliver to the Company such
documents and  instruments  of conveyance as may be necessary or  appropriate in
the opinion of counsel to the Company to effect such Transfer and to confirm the
agreement of the  transferee  to be bound by the  provisions of this Section 12,
and to comply with the  requirements  of Code  Section  6050K.  In the case of a
Transfer of Interests  involuntarily  by operation of law, the Transfer shall be
confirmed by presentation to the Company of legal evidence of such Transfer,  in
form and substance  satisfactory to counsel to the Company. In all cases, unless
the  requirements of this sentence have been waived by the Governing  Board, the
Company shall be reimbursed by the  transferor  and/or  transferee for all costs
and expenses that it reasonably incurs in connection with such Transfer.

         (b) The transferor  and  transferee  shall furnish the Company with the
transferee's taxpayer identification number, sufficient information to determine
the transferee's  initial tax basis in the Interest  transferred,  and any other
information  reasonably  necessary  to permit the  Company to file all  required
federal and state tax returns and other legally required information  statements
or returns.  Without limiting the generality of the foregoing, the Company shall
not be  required  to  make  any  distribution  otherwise  provided  for in  this
Agreement  with respect to any  transferred  Interest until it has received such
information.






                                                                             44

         (c)  Either  (i)  the   Transfer   occurs   pursuant  to  an  effective
registration  statement  under  the  Securities  Act  and any  applicable  state
securities law or (ii) the Transfer is exempt from  registration or is otherwise
in compliance with the Securities Act and applicable  state  securities law, and
the transferor has furnished to the Company  evidence (which may but need not in
the discretion of the Governing Board include an opinion of counsel)  reasonably
satisfactory to the Governing Board.

         (d) The  Transfer  will not  cause  the  Company  to be deemed to be an
"investment  company" under the Investment Company Act of 1940, as amended,  and
the  transferor  shall provide an opinion of counsel to such effect,  unless the
Governing  Board waives the  requirement  that such  opinion be  provided.  Such
opinion and counsel shall be reasonably satisfactory to the Governing Board.

         (e) The  Transfer  will not  cause  the  Company  to be  deemed to be a
publicly traded partnership under Code Section 7704.

         12.4     Prohibited Transfers.

         Any purported  Transfer of an Interest that is not a Permitted Transfer
shall be null and void and of no force or effect whatever; provided that, if the
Company is required to recognize a Transfer that is not a Permitted Transfer (or
if the Company,  in its sole discretion,  elects to recognize a Transfer that is
not a Permitted Transfer), the Interest transferred shall be strictly limited to
the  transferor's  rights to allocations and  distributions  as provided by this
Agreement  with  respect to the  transferred  Interest,  which  allocations  and
distributions  may be applied  (without  limiting  any other legal or  equitable
rights of the Company) to satisfy any debts,  obligations,  or  liabilities  for
damages  that the  transferor  or  transferee  of such  Interest may have to the
Company.

         In the case of a Transfer or attempted  Transfer of an Interest that is
not a Permitted  Transfer,  the parties engaging or attempting to engage in such
Transfer  shall be liable to  indemnify  and hold  harmless  the Company and the
other  Members from all cost,  liability,  and damage that the Company or any of
such indemnified Members may incur (including,  without limitation,  incremental
tax  liabilities,  lawyers'  fees and  expenses) as a result of such Transfer or
attempted  Transfer and efforts to enforce the  indemnity  granted  hereby.  Any
indemnification  payments  made to the Company  under this Section  12.4, to the
extent paid with respect to costs,  liabilities  or other damages  incurred by a
Member, shall immediately be paid by the Company to such Member.

         12.5     Rights of Unadmitted Assignees.

         A  Person  who  acquires  an  Interest  but  who is not  admitted  as a
substituted  Member  pursuant to Section 12.6 hereof  shall be entitled  only to
allocations and distributions with respect





                                                                             45

to such Interest in accordance  with this  Agreement,  and shall not have any of
the rights of a Member under the Act or this Agreement.

         12.6     Admission of Substituted Members.

         Subject to the other  provisions of this Section 12, a transferee of an
Interest  may be  admitted  to the  Company as a  substituted  Member  only upon
satisfaction of each of the conditions set forth in this Section 12.6:

         (a) (i) The non-transferring  Members consent to such admission,  which
consent  may be given or withheld in the sole and  absolute  discretion  of each
such Member,  or (ii) the Interest with respect to which the transferee is being
admitted was acquired by means of a Permitted Transfer;

         (b) The transferee of an Interest shall, by written  instrument in form
and  substance  reasonably  satisfactory  to the Director  (and,  in the case of
clause (ii) below,  the transferor  Member),  (i) accept and adopt the terms and
provisions  of this  Agreement,  including  this  Section 12 and (ii) assume the
obligations  of the  transferor  Member under this Agreement with respect to the
transferred  Interest.  The  transferor  Member shall be released  from all such
assumed   obligations  except  (i)  those  obligations  or  liabilities  of  the
transferor Member arising out of a breach of this Agreement and (ii) in the case
of a  Transfer  to  any  Person  other  than  a  Member,  those  obligations  or
liabilities  of the  transferor  Member  based on events  occurring,  arising or
maturing prior to the date of Transfer;

         (c) Unless the requirements of this Section 12.6(c) have been waived by
the Governing  Board,  the  transferee  pays or  reimburses  the Company for all
reasonable  legal,  filing,  and  publication  costs that the Company  incurs in
connection  with the admission of the transferee as a Member with respect to the
Transferred Interest; and

         (d) If required by the Governing  Board,  the transferee  (other than a
transferee that was a Member prior to the Transfer) shall deliver to the Company
evidence of the  authority  of such Person to become a Member and to be bound by
all of the  terms and  conditions  of this  Agreement,  and the  transferee  and
transferor  shall  each  execute  and  deliver  such  other  instruments  as the
Governing Board  reasonably  deems necessary or appropriate to effect,  and as a
condition to, such  Transfer,  including  amendments to the  Certificate  or any
other  instrument  filed  with  the  State of  Delaware  or any  other  state or
governmental authority.

         12.7     Distributions and Allocations in Respect of Transferred 
Interests.

         If all  or  any  portion  of an  Interest  is  Transferred  during  any
Allocation  Year in compliance  with the provisions of this Section 12, Profits,
Losses,  each item thereof,  and all other items attributable to the Transferred
Interest for such  Allocation  Year shall be divided and  allocated  between the
transferor  and the  transferee by taking into account their varying  Percentage
Interests





                                                                             46

during  the  Fiscal  Year in  accordance  with Code  Section  706(d),  using any
conventions permitted by law and agreed to by the transferor and transferee. All
distributions  on or  before  the  date of such  Transfer  shall  be made to the
transferor,  and all  distributions  thereafter shall be made to the transferee.
Solely for purposes of making such  allocations and  distributions,  the Company
shall  recognize  such  Transfer  not later than the end of the  calendar  month
during which it is given notice of such Transfer;  provided that, if the Company
is given  notice of a  Transfer  at least ten (10)  Business  Days  prior to the
Transfer,  the  Company  shall  recognize  such  Transfer as of the date of such
Transfer;  and  provided  further  that if the Company does not receive a notice
stating the date such Interest was transferred and such other information as the
Director may  reasonably  require  within  thirty (30) days after the end of the
Allocation Year during which the Transfer  occurs,  then all such items shall be
allocated,  and all distributions shall be made, to the Person who, according to
the books and records of the Company,  was the owner of the Interest on the last
day of such  Allocation  Year.  Neither the Company nor the Director shall incur
any liability for making  allocations and  distributions  in accordance with the
provisions of this Section 12.7,  whether or not the Director or the Company has
knowledge of any Transfer of ownership of any Interest.

         12.8     Right of First Refusal

         (a) In the event that any Member has a binding,  written  offer from an
unrelated  Person for the  Transfer  of its  Interest  other than  pursuant to a
Permitted  Transfer  and desires to accept  such offer to purchase (a  "Proposed
Transfer"),  such Member (the "Selling Member") shall deliver to the Company and
the remaining Members (the "Non-Selling Members") written notice of the material
terms of such offer,  including  the  proposed  purchaser  thereof,  the amount,
nature and payment schedule of the consideration to be received, the conditions,
if any,  associated  therewith  and any other  material  terms of such offer (an
"Offer Notice").  The Offer Notice shall constitute an irrevocable  offer by the
Selling  Member to sell all (but not less than all) of its  Interest  subject to
the Proposed Transfer (i) first, to the Non-Selling  Members and (ii) second, if
and only if at that time there are more than two (2) Members,  to the Company on
terms and  conditions of the Proposed  Transfer,  except that a purchaser  under
this  Section  12.8 shall  have the right to pay cash in an amount  equal to the
Fair Market Value of any Non-Cash Consideration (the "Right of First Refusal").

         (b) During the First Offer Period, each Non-Selling Member may elect to
purchase all or any portion of such  Non-Selling  Member's Offer  Percentage (as
hereinafter  defined)  of the  Interest  subject  to the  Proposed  Transfer  by
delivering  written  notice  of such  election  stating  the  percentage  of the
Interest to be purchased (an  "Election  Notice") to the Company and the Selling
Member prior to the  expiration  of the First Offer  Period.  As used herein,  a
Member's Offer Percentage  shall be a fraction,  the numerator of which is equal
to the Percentage Interest of the Company held by such Member on the date of the
Offer Notice and the  denominator of which is the  Percentage  Interests held on
such date by all Non-Selling Members (the "Offer  Percentage");  provided that a
Member  shall have the right in an Election  Notice to agree to purchase  all or
any portion of the Interest  that could be purchased by other  Members;  and, if
one or more Members do not deliver an Election





                                                                             47

Notice or elect to purchase less than their respective Offer  Percentages,  then
the portion of the Interest that could have been purchased by such Members shall
be purchased by Members  that,  in an Election  Notice,  agreed to purchase such
portion of the Interest,  and each such Member shall purchase the portion of the
Interest indicated in an Election Notice,  unless the sum of the portions of the
Interest  exceeds the  Interest so  available  for  purchase,  in which case the
portions  of the  Interest  shall  be  purchased  pro  rata on the  basis of the
proportionate  amount of the Offer  Percentage  of such  Members that deliver an
Election  Notice.  The failure by any Non-Selling  Member to deliver an Election
Notice  during the First Offer  Period shall be deemed to be an election by such
Member not to purchase any of the Interest subject to the Proposed Transfer.

         (c) If the  Non-Selling  Members do not elect  during  the First  Offer
Period to purchase all of the Interest subject to the Proposed Transfer,  during
any Second  Offer  Period,  the Company may elect to purchase  all (but not less
than all) of the Interest that the Non-Selling Members did not elect to purchase
during the First Offer Period by  delivering  an Election  Notice to the Selling
Member prior to the  expiration of the Second Offer  Period.  The failure by the
Company to deliver an Election  Notice  during any Second  Offer Period shall be
deemed to be an election by the  Company  not to  purchase  any of the  Interest
subject to the Proposed Transfer.

         (d) If the Non-Selling Members and, if applicable,  the Company (either
individually  or  collectively)  do not elect to  purchase  all of the  Interest
subject to the  Proposed  Transfer,  the  Selling  Member  may,  Transfer to the
purchaser  named in the Offer Notice (the "Third Party  Purchaser") all (but not
less than all) of the Interest  subject to the Proposed  Transfer in  accordance
with the terms and conditions set forth in the Offer Notice; provided,  however,
that if the Selling  Member has not  consummated  the Transfer of such  Interest
within the 45 Business Day period following any Second Offer Period,  all of the
restrictions  on Transfer  contained in this Agreement  shall again be in effect
with respect to such Interest.

         (e) If the  consideration  for the sale of  Interest  pursuant  to this
Right of First Refusal is cash  consideration,  the purchase price to be paid by
each of the Non-Selling Members and the Company,  as applicable,  shall be equal
to the  total  consideration  set forth in the Offer  Notice  multiplied  by the
percentage of such Interest being  purchased by such  Non-Selling  Member or the
Company, as applicable.  If the consideration for the Proposed Transfer consists
of consideration  that is other than cash  consideration  payable in immediately
available funds at the closing thereunder ("Non-Cash Consideration") or consists
of a combination of cash consideration and Non-Cash Consideration,  the purchase
price shall be cash in an amount  equal to the total of the cash  consideration,
if any, and the Fair Market Value of the Non-Cash Consideration as determined in
accordance with Section 12.9 hereof.

         (f) The purchase  and sale of Interest  pursuant to this Right of First
Refusal  shall be  consummated  at a closing  that shall occur at the  principal
business  office of the Company within 20 Business Days following the expiration
of the relevant Offer Period,  or at such other place or time as may be mutually
acceptable to the parties.  At such closing,  the Selling Member shall deliver a
certificate or other instrument representing the Interest being purchased,  free
and clear of all liens,





                                                                             48

claims,  encumbrances  (other than as a result of this Agreement) and defects in
title and duly  endorsed  for  Transfer  to the  appropriate  purchaser  and, in
exchange therefor,  the purchaser of such Interest shall pay the purchase price,
as provided in Section 12.8(e) hereof,  at such closing by bank wire transfer of
immediately  available  funds to a bank  account  designated  in  writing by the
Selling Member at least three Business Days prior to such closing.

         12.9     Determination of Fair Market Value.

         In the event that a determination  of the fair market value of Non-Cash
Consideration  is required  pursuant to the Right of First Refusal,  the Selling
Member shall specify in the  applicable  Offer Notice its good faith estimate of
the fair market value of any  Non-Cash  Consideration  to be paid in  connection
with the proposed  transfer.  If a majority of the disinterested  members of the
Governing  Board agrees with the  estimated  fair market value of such  Non-Cash
Consideration,  the  estimate  shall be deemed to be the Fair Market  Value (the
"Fair Market Value")  thereof for purposes of this  Agreement.  If a majority of
the  disinterested  members  of the  Governing  Board  does not  agree  with the
estimated fair market value, the Governing Board shall,  within 10 Business Days
of receipt of the Offer Notice,  deliver to the Selling Member written notice of
its  disagreement  and shall,  for a period of 10 Business Days after delivering
such notice,  negotiate  with the Selling  Member for the purpose of determining
the fair market value of the Non-Cash  Consideration  that is  acceptable to the
Governing Board and the Selling  Member.  If the Governing Board and the Selling
Member  are unable to agree on a fair  market  value  during the  aforementioned
negotiation  period, the Company and the Selling Member shall appoint a mutually
agreeable  appraiser of  recognized  standing  with respect to the nature of the
property constituting the Non-Cash Consideration to complete an appraisal of the
property constituting the Non-Cash Consideration.  Such appraiser shall render a
binding and  non-appealable  appraisal  of the Fair Market Value of the property
constituting  the  Non-Cash  Consideration  within  10  Business  Days  of  such
appraiser's  appointment  or, if it is not reasonably  possible to complete such
appraisal  in such  time  period,  such  longer  period  as shall be  reasonably
necessary  to complete  such  appraisal  (not to exceed 30 Business  Days).  The
Company  and the Selling  Member  each shall bear  one-half of the costs of such
appraisal.

         12.10    Tag-Along and Bring-Along Rights.

         (a)      Exercise of "Tag-Along Right."

                  (i)  Transfers  by the  Majority  Member.  In the  event  that
Magellan's or Crescent's  Percentage  Interest in the Company  decreases to less
than 25%, the other party (the "Majority Member") shall not Transfer all or part
of its Interest without  complying with the provisions of this Section 12.10(a).
If the Majority  Member  desires to Transfer  all or part of its  Interest  (the
"Offered  Interest")  to a  proposed  transferee,  each of the other  Members (a
"Remaining  Member") may elect (the "Tag-Along  Right") to sell to such proposed
transferee,  on the same terms,  consideration (on a Percentage  Interest basis)
and conditions as were offered to the Majority Member,  all of the Interest then
owned by each Remaining Member (if the Majority





                                                                             49

Member is  proposing  to sell all of its  Interest) or a portion of its Interest
(if the Majority  Member is proposing to sell less than all of its  Interest) in
the same proportion as the Interest proposed to be sold by the Majority Member.

                  (ii)  Notification  of Proposed  Transfers.  In the event of a
proposed  Transfer subject to this Section  12.10(a),  the Majority Member shall
notify in writing all Remaining  Members of the proposed  Transfer.  Such notice
shall set forth: (i) the name of the proposed  transferee and the portion of the
Interest that is to be  transferred  by the Majority  Member,  (ii) the proposed
amount and form of consideration  and terms and conditions of payment offered by
such  proposed  transferee,  and (iii)  that the  proposed  transferee  has been
informed of the Tag-Along  Right  provided for in this Section  12.10(a) and has
agreed to purchase additional Interests in accordance with the terms hereof. The
Tag-Along  Right may be  exercised  by any  Remaining  Member by  delivery  of a
written notice to the Company (the "Tag-Along  Notice") within 30 days following
receipt of the notice  specified in the immediately  preceding  sentence stating
that the Remaining Member wishes to participate in such transfer to the proposed
transferee by including such Remaining Member's Interest (or a portion thereof).
The Tag-Along Notice shall also specify, in the event that only a portion of the
Majority  Member's  Interest is being  purchased,  whether or not the  Remaining
Member  wishes  to have  any  additional  portion  (up to  all) of his  Interest
purchased  if any  other  Remaining  Member  does  not  exercise  such  Member's
Tag-Along Right. In the event that any proposed transferee does not purchase the
Interest of the  Majority  Member or  Remaining  Member who has  exercised  such
Member's Tag-Along Right on the same terms,  consideration (if applicable,  on a
Percentage  Interest  basis)  and  conditions  as those set forth in the  notice
delivered  by the Majority  Member then the sale by the  Majority  Member to the
proposed  transferee shall be void ab initio and of no force and effect, and the
Company shall not recognize or give effect to such transfer. Notwithstanding the
foregoing,  if any  Remaining  Member  shall not exercise  its  Tag-Along  Right
provided for herein,  the other  Remaining  Members  shall have the right,  upon
receipt of written  confirmation from the Remaining Members not participating in
the Tag-Along Right, to include in their respective  Tag-Along  Notices,  and to
have purchased by the proposed transferee,  an additional Interest equal to each
such  Member's pro rata  portion of the  Interest not included in the  Tag-Along
Right by the non-electing Remaining Member.

         (b)      Exercise of "Bring-Along Right"

                  (i)  Transfers  by the  Majority  Member.  In the  event  that
Magellan's or New  Crescent's  Percentage  Interest in the Company  decreases to
less than 25% and the  Majority  Member  proposes to Transfer  its Interest to a
proposed third party transferee in an arms-length transaction, then the Majority
Member may, at its option,  require (the "Bring-Along  Right") each other Member
to  sell  all  of its  Interest  (the  "Designated  Interest")  to the  proposed
transferee,  at the  same  time  and  on the  same  terms,  consideration  (on a
Percentage  Interest  basis)  and  conditions  at which the  Majority  Member is
selling its Interest.






                                                                             50

                  (ii)  Notification of Proposed  Transfer.  The Majority Member
shall exercise its  Bring-Along  Right by sending written notice of the exercise
of the  Bring-Along  Right to each of the other  Members.  Such notice shall set
forth:  (i) the name and address of the  proposed  transferee  and the  proposed
amount and form of consideration to be paid by the proposed  transferee and (ii)
the terms and conditions of such  transaction.  Such notice shall be accompanied
by copies of all documents  required to be executed by the Members in connection
with such transaction.  Within 10 days following receipt of the notice,  each of
the other  Members  shall deliver to a  representative  of the Majority  Member,
designated in the notice,  instruments (or other appropriate documents necessary
to transfer the Designated  Interest)  representing the Designated Interest held
by such Member, duly endorsed,  together with fully executed copies of all other
documents  required  to  be  executed  in  connection  with  such  transactions,
including  (if  requested)  customary  legal  opinions  from the counsel to such
Member.  In the event that a Member should fail to deliver such  instruments  to
the Majority Member,  the Company shall cause its books and records to show that
such Designated Interest is bound by the provisions of this Section 12.10(b) and
that such  Designated  Interest  shall be  transferred  only to the third  party
purchaser upon surrender for transfer by the holder thereof. If requested by the
Majority  Member,  each Member  shall also cause a  representative  that is duly
authorized  to execute  documents  and to act on behalf of such Member to attend
the  closing  of the  transaction  and to take such  actions  as are  reasonably
requested by the Majority Member.

                  (iii) Return of Designated Interest. If, within 120 days after
the Majority  Member gives such notice,  the sale of the Designated  Interest by
the Majority Member in accordance herewith has not been completed,  the Majority
Member  shall  return to each  Member  all  instruments  or other  documentation
representing  the  Designated  Interest  that  such  Member  delivered  for sale
pursuant hereto.

                  (iv) Payment for Designated Interest.  Simultaneously with the
consummation  of the sale of the Designated  Interest by the Majority Member and
the other Members pursuant to this Section  12.10(b),  the Majority Member shall
remit,  or cause the transferee to remit, to each of the Members the total sales
price  of the  Designated  Interest  sold  pursuant  thereto  (net of the  other
Members' pro rata share of any  transaction  expenses),  and shall  furnish such
other  evidence of the  completion  and time of completion of such sale or other
disposition  and  the  terms  thereof  as may be  reasonably  requested  by such
Members.


                                   SECTION 13.

                                POWER OF ATTORNEY

         13.1     Directors as Attorneys-In-Fact.

         Each  Member  hereby  makes,  constitutes,  and  appoints  each  of the
Directors,  severally,  with full power of substitution and resubstitution,  its
true and lawful attorney-in-fact for it and in





                                                                             51

its  name,  place,  and  stead and for its use and  benefit,  to sign,  execute,
certify, acknowledge, swear to, file, publish and record (i) all certificates of
formation,  amended name or similar  certificates,  and other  certificates  and
instruments  (including  counterparts  of this  Operating  Agreement)  which the
Governing  Board may deem necessary to be filed by the Company under the laws of
the State of Delaware or any other jurisdiction in which the Company is doing or
intends to do business in order to  preserve  its status as a limited  liability
company or conduct  business  in such  state;  (ii) any and all duly  authorized
amendments,  restatements  or  changes  to  this  Operating  Agreement  and  the
instruments  described  in clause (i), as now or  hereafter  amended,  which the
Governing  Board may deem  necessary to effect a change or  modification  of the
Company in accordance  with the terms of this  Operating  Agreement,  including,
without limitation, amendments, restatements or changes to reflect the admission
of any  substituted  Member and the disposition by any Member of its interest in
the Company;  (iii) all certificates of cancellation and other instruments which
the Liquidator  deems  necessary or appropriate  to effect the  dissolution  and
termination of the Company  pursuant to the terms of this  Operating  Agreement;
and (iv) any other  instrument  which is now or may hereafter be required by law
to be filed on behalf of the  Company or is deemed  necessary  by the  Governing
Board to comply with any laws,  rules or  regulations  or as may be necessary to
enable the Company to carry out fully the provisions of this Operating Agreement
in accordance with its terms. Each Member authorizes each such  attorney-in-fact
to take any further action which such attorney-in-fact  shall consider necessary
in   connection   with  any  of  the   foregoing,   hereby   giving   each  such
attorney-in-fact  full power and  authority to do and perform each and every act
or thing  whatsoever  requisite to be done in  connection  with the foregoing as
fully as such Member might or could do personally, and hereby ratify and confirm
all that any such  attorney-in-fact  shall  lawfully do, or cause to be done, by
virtue thereof or hereof.

         13.2     Nature of Special Power.

         The power of attorney granted to each Director pursuant to this Section
13:

         (a)      Is a special power of attorney coupled with an interest and is
irrevocable;

         (b) May be  exercised  by any  such  attorney-in-fact  by  listing  the
Members executing any agreement, certificate, instrument, or other document with
the single signature of any such attorney-in-fact acting as attorney-in-fact for
such Members; and

         (c) Shall  survive and not be affected  by the  subsequent  Bankruptcy,
insolvency, dissolution, or cessation of existence of a Member and shall survive
the  delivery  of an  assignment  by a Member of the  whole or a portion  of its
interest in the Company  (except that where the  assignment  is of such Member's
entire  interest in the Company and the assignee,  with the consent of the other
Members,  is  admitted as a  substituted  Member,  the power of  attorney  shall
survive the  delivery of such  assignment  for the sole  purpose of enabling any
such  attorney-in-fact  to effect such  substitution)  and shall  extend to such
Member's or assignee's successors and assigns.






                                                                             52

                                   SECTION 14.

                           DISSOLUTION AND WINDING UP

         14.1     Dissolution Events.

         (a)      Dissolution.  The Company shall dissolve and shall commence
winding up and liquidating upon the first to occur of any of the following 
(each a "Dissolution Event"):

                  (1)      The unanimous vote of the Members to dissolve, wind 
         up, and liquidate the Company;

                  (2)      A judicial determination that an event has occurred 
         that makes it unlawful, impossible or impractical to carry on the 
         Business;

                  (3)      The expiration of the Company's term;

                  (4)      The entry of a decree of judicial dissolution; or

                  (5) The  Bankruptcy,  retirement,  resignation or expulsion of
         any  Member;  provided  that  any  such  event  will  not be  deemed  a
         Dissolution  Event if within  ninety  (90) days after such  Dissolution
         Event if the  Company  has one (1) or more  remaining  Members and such
         Member or Members  agree to continue  the  business  and affairs of the
         Company.

         (b)  Reconstitution.  If it is  determined,  by a  court  of  competent
jurisdiction,  that the  Company  has  dissolved  prior to the  occurrence  of a
Dissolution  Event,  then  within an  additional  ninety  (90) days  after  such
determination  (the  "Reconstitution  Period"),  all of the Members may elect to
reconstitute  the  Company  and  continue  its  Business  on the same  terms and
conditions  set  forth in this  Agreement  by  forming a new  limited  liability
company on terms identical to those set forth in this Agreement.  Unless such an
election is made within the  Reconstitution  Period, the Company shall liquidate
and wind up its affairs in  accordance  with  Section  14.2  hereof.  If such an
election is made within the Reconstitution Period, then:

                  (1)      The reconstituted limited liability company shall 
         continue until the occurrence of a Dissolution Event as provided in 
         this Section 14.1(a);

                  (2)  All  necessary  steps  shall  be  taken  to  cancel  this
         Agreement  and  the  Certificate  and to  enter  into  a new  operating
         agreement and certificate of  organization;  provided that the right of
         the  Members to select  successor  Directors  and to  reconstitute  and
         continue the Business  shall not exist and may not be exercised  unless
         the Company has received an opinion of counsel that the exercise of the
         right would not result in the loss of limited  liability  of any Member
         and neither the Company nor the reconstituted limited





                                                                             53

         liability company would cease to be treated as a partnership for U.S. 
         federal income tax purposes upon the exercise of such right to
         continue.

         14.2     Winding Up.

         Upon the occurrence of a Dissolution  Event, the Company shall continue
solely  for the  purposes  of  winding  up its  affairs  in an  orderly  manner,
liquidating its assets,  and satisfying the claims of its creditors and Members,
and no Member shall take any action that is inconsistent  with, or not necessary
to or  appropriate  for, the winding up of the  Company's  business and affairs;
provided  that  all  covenants   contained  in  this  Operating   Agreement  and
obligations  provided for in this Operating Agreement shall continue to be fully
binding upon the Members  until such time as the  Property has been  distributed
pursuant to this Section 14.2 and the Certificate has been canceled  pursuant to
the Act. The Liquidator  shall be responsible  for overseeing the winding up and
dissolution of the Company,  which winding up and dissolution shall be completed
within  ninety  (90)  days  of the  occurrence  of the  Dissolution  Event.  The
Liquidator shall take full account of the Company's liabilities and Property and
shall cause the  Property or the proceeds  from the sale thereof (as  determined
pursuant to Section 12.6), to the extent sufficient therefor,  to be applied and
distributed, to the maximum extent permitted by law, in the following order:

         (a) First,  to  creditors  (including  Members  and  Directors  who are
creditors,  to the extent otherwise  permitted by law) in satisfaction of all of
the Company's Debts and other  liabilities  (whether by payment or the making of
reasonable  provision for payment  thereof),  other than  liabilities  for which
reasonable  provision for payment has been made and liabilities for distribution
to Members under Section 18-601 or 18-604 of the Act;

         (b)      Second, except as provided in this Agreement, to Members and 
former Members of the Company in satisfaction of liabilities for distribution 
under Sections 18-601 or 18-604 of the Act; and

         (c) The balance, if any, to the Members in accordance with the positive
balance in their Capital  Accounts,  after giving  effect to all  contributions,
distributions and allocations for all periods.

         14.3     Rights of Members.

         Except as otherwise provided in this Agreement,  each Member shall look
solely to the Property of the Company for the return of its  investment  and has
no right or power to  demand  or  receive  Property  other  than  cash  from the
Company.  If the assets of the Company  remaining  after payment or discharge of
the  Debts or  liabilities  of the  Company  are  insufficient  to  return  such
investment,  the Members shall have no recourse against the Company or any other
Member or Director.






                                                                             54

         14.4     Notice of Dissolution/Termination.

         (a) In the event a Dissolution  Event  occurs,  the  Liquidator  shall,
within thirty (30) days  thereafter,  provide  written notice thereof to each of
the Members and to all other  parties with whom the Company  regularly  conducts
business (as determined in the discretion of the  Liquidator)  and shall publish
notice thereof in a newspaper of general  circulation in each place in which the
Company  regularly  conducts  business (as  determined in the  discretion of the
Liquidator).

         (b) Upon completion of the  distribution  of the Company's  Property as
provided in this Section 14, the Company shall be terminated, and the Liquidator
shall cause the filing of the  Certificate of  Cancellation  pursuant to Section
18-203 of the Act and shall take all such other  actions as may be  necessary to
terminate the Company.

         14.5     The Liquidator.

         (a) Definition.  The "Liquidator"  shall mean a Person appointed by the
Governing  Board to oversee  the  dissolution  of the Company and shall have the
power of attorney granted to the Directors pursuant to Section 13.

         (b) Fees.  The Company is  authorized  to pay a  reasonable  fee to the
Liquidator  for  its  services  performed  pursuant  to this  Section  14 and to
reimburse  the  Liquidator  for its  reasonable  costs and expenses  incurred in
performing  those  services,  other than a  Liquidator  that is also a Member or
Director.

         (c) Indemnification.  The Company shall indemnify,  save harmless,  and
pay all judgments and claims against such Liquidator or any officers, directors,
stockholders, agents or employees of the Liquidator relating to any liability or
damage incurred by reason of any act performed or omitted to be performed by the
Liquidator, or any officers, directors, stockholders, agents or employees of the
Liquidator  in  connection  with  the  winding  up  of  the  Company,  including
reasonable  attorneys'  fees  incurred  by the  Liquidator,  officer,  director,
stockholder,  agent or  employee  in  connection  with the defense of any action
based  on any  such  act or  omission,  which  attorneys'  fees  may be  paid as
incurred,  except to the extent such liability or damage is caused by the fraud,
intentional  misconduct of, or a knowing violation of the laws by the Liquidator
which was material to the cause of action.

         14.6     Form of Liquidating Distributions.

         For purposes of making  distributions  required by Section 14.2 hereof,
the  Liquidator  may determine  whether to distribute  all or any portion of the
Property  in-kind or to sell all or any portion of the Property  and  distribute
the proceeds therefrom.

                                                                             55

                               MANAGEMENT DEADLOCK

         15.1     Existence of a Deadlock

         A deadlock of the  Governing  Board (a  "Deadlock")  shall be deemed to
exist if the Governing  Board shall be unable to reach agreement by the required
vote on (i) a Major Decision,  (ii) a decision involving the expenditure of more
than $____  million or (iii) a decision  relating to the  election of  Executive
Officers,  provided  that any matter  referred to in (i), (ii) or (iii) has been
submitted for consideration at two successive meetings.

         15.2     Discussions by Chief Executive Officers

         If a Deadlock  exists,  the Members or Governing Board, as appropriate,
shall  negotiate in good faith and use their  respective best efforts to resolve
such Deadlock.  If, however,  after 20 Business Days such Deadlock remains,  any
Member, by giving notice to the other Members, may request that such Deadlock be
referred for resolution to the Chief Executive Officer of Magellan and the Chief
Executive  Officer of New Crescent (the "Chief  Executive  Officers")  (or, if a
Member's Chief Executive  Officer is on the Company's  Governing Board,  another
senior  officer or  director  designated  by the  Member).  The Chief  Executive
Officers shall meet within 20 Business Days thereafter and shall attempt in good
faith to resolve such Deadlock. Any resolution agreed to in writing by the Chief
Executive Officers shall be final and binding on the Company and the Members, so
long as the resolution is not inconsistent with any provision of this Agreement.

         15.3     Buy/Sell Option

         In the event of a failure  to resolve a  Deadlock  pursuant  to Section
15.2  within  forty (40)  Business  Days after a Member  makes the  request  for
resolution by the Chief Executive  Officers (an "Unresolved  Deadlock"),  either
Member, at any time thereafter,  shall be authorized to offer to purchase all of
the Interest of the other  Member  pursuant to the  procedures  set forth in the
following provisions:

         (a) Either  New  Crescent  or  Magellan  (the  initiating  party  being
hereinafter  referred to as the "Offering  Party") may by written  notice to the
other party (the  "Responding  Party") state the aggregate  fair value of all of
the  outstanding  Interests in the Company (the "Stated  Value").  The giving of
such  notice  of  Stated  Value  by the  Offering  Party  shall  constitute  the
irrevocable  offer  of such  party to  purchase  all of the  Responding  Party's
Interest in the Company or to sell to the  Responding  Party all of the Offering
Party's  Interest in the Company for the respective  purchase price provided for
hereinafter.

         (b)  Within  thirty  (30)  days  after  receipt  of  said  notice,  the
Responding Party shall determine  whether it shall sell its Interest or purchase
the Offering  Party's  Interest in the Company as provided herein and shall give
written notice to the Offering Party of its decision and shall designate in that
notice which party will be the "Selling Party" and which party shall be the





                                                                             56

"Purchasing  Party." If the  Responding  Party  shall fail to give notice of its
election  within the said  15-day  period,  then the  Responding  Party shall be
deemed to have given  notice of its  election to sell all of its Interest in the
Company pursuant to the provisions hereof.

         (c) Within  forty-five (45) days after the date on which the Responding
Party receives the notice of Stated Value from the Offering Party,  New Crescent
and Magellan shall close the purchase of all of the Interest in the Company then
owned by the Selling  Party.  The purchase  price for such Interest shall be the
product  obtained by multiplying the Stated Value times the Percentage  Interest
owned by the Selling Party.  The  Purchasing  Party shall pay the purchase price
for such  Interest in cash or by  certified  check at the  closing.  The Selling
Party shall deliver to the  Purchasing  Party at the closing such  documents and
instruments as may be necessary or desirable,  in the opinion of counsel for the
Purchasing  Party, to effect the transfer of the Selling Party's Interest to the
Purchasing Party, which Interest shall be free and clear of all Encumbrances.

         (d) If the  Selling  Party is  Magellan  and,  after  the  close of the
purchase of  Magellan's  Interest by New  Crescent,  the Company fails to pay to
Magellan all amounts due Magellan  under the Franchise  Agreement,  New Crescent
acknowledges  that  Magellan  shall have the rights  granted to  Magellan  under
Section 15 of the Franchise Agreement.

         15.4     Continuation of Business

         During the  pendency of any  Deadlock  relating to the  approval of any
Annual Budget for an ensuing Fiscal Year, the Governing  Board and the President
shall conduct the Business of the Company in accordance  with Section  8.3(c) of
this Agreement.

         No Member  shall take any  action  that could  impair  materially  such
Member's ability to perform its duties and obligations under this Agreement.
