Section 5.01(b)(i) is insufficient to allow the Adjusted Capital Account balance
of each Member to equal such Member's share of the LLC Capital, such Net Profits
or Net Losses shall be allocated among the Members in such a manner as to
decrease the differences between the Members' respective Adjusted Capital
Account balances and their respective shares of the LLC Capital in proportion to
such differences.

          (d)  Allocations of Net Profits and Net Losses provided for in this
Section 5.01 shall generally be made as of the end of the fiscal year of the
LLC; provided, however, that allocations of items of Net Profits and Net Losses
     --------- -------
described in clause (vi) of the definition of

                                      -9-
<PAGE>

"Net Profits" and "Net Losses" shall be made at the time deemed realized as
described in the definition of "Capital Account."

     5.02 Regulatory Allocations.
          ----------------------

Notwithstanding the provisions of Section 5.01 above, the following allocations
of Net Profits, Net Losses and items thereof shall be made in the following
order of priority:

          (a)  Items of income or gain (computed with the adjustments contained
in paragraphs (i), (ii) and (iii) of the definition of "Net Profits and Net
Losses") for any taxable period shall be allocated to the Members in the manner
and to the minimum extent required by the "minimum gain chargeback" provisions
of Treasury Regulation Section 1.704-2(f) and Treasury Regulation Section 1.704-
2(i)(4).

          (b)  All "nonrecourse deductions" (as defined in Treasury Regulation
Section 1.704-2(b)(1)) of the LLC for any year shall be allocated to the Members
in proportion to their Percentage Interests; provided, however, that nonrecourse
                                             --------- -------
deductions attributable to "partner nonrecourse debt" (as defined in Treasury
Regulation Section 1.704-2(b)(4)) shall be allocated to the Members in
accordance with the provisions of Treasury Regulation Section 1.704-2(i)(1).

          (c)  Items of income or gain (computed with the adjustments contained
in paragraphs (i), (ii) and (iii) of the definition of "Net Profits and Net
Losses") for any taxable period shall be allocated to the Members in the manner
and to the extent required by the "qualified income offset" provisions of
Treasury Regulation Section 1.704-1(b)(2)(ii)(d).

          (d)  In no event shall Net Losses of the LLC be allocated to a Member
if such allocation would cause or increase a negative balance in such Member's
Adjusted Capital Account (determined, for purposes of this Section 5.02(d) only,
by increasing the Member's Capital Account balance by the amount the Member is
obligated to restore to the LLC pursuant to Treasury Regulation Section 1.704-
1(b)(2)(ii)(c)).

          (e)  In the event that items of income, gain, loss or deduction are
allocated to one or more Members pursuant to any of subsections (a) through (d)
above (the "Original Allocation"), subsequent items of income, gain, loss or
deduction will first be allocated (subject to the provisions of subsections (a)
through (d) above) to the Members in a manner designed to result in each Member
having a Capital Account balance equal to what it would have been had the
Original Allocation not occurred; provided, however, that no such allocation
                                  --------- -------
shall be made pursuant to this subsection (e) if (i) the Original Allocation had
the effect of offsetting a prior Original Allocation or (ii) the Original
Allocation likely (in the opinion of the LLC's accountants) will be offset by
another Original Allocation in the future (e.g., an Original Allocation of
"nonrecourse deductions" under subsection (b) above that likely will be offset
by a subsequent "minimum gain chargeback" under subsection (a) above).

          (f)  Except as otherwise provided herein or as required by Code
Section 704, for tax purposes, all items of income, gain, loss, deduction or
credit shall be allocated to the

                                      -10-
<PAGE>

Members in the same manner as are Net Profits and Net Losses; provided, however,
                                                              --------  -------
that if the Carrying Value of any property of the LLC differs from its adjusted
basis for tax purposes, then items of income, gain, loss, deduction or credit
related to such property for tax purposes shall be allocated among the Members
so as to take account of the variation between the adjusted basis of the
property for tax purposes and its Carrying Value in the manner provided for
under Code Section 704(c).

     5.03 Allocations Upon Transfer or Admission. In the event that a Member
          --------------------------------------
acquires an interest in the LLC either by Transfer from another Member or by
acquisition from the LLC, the LLC shall close its books as of the date of the
acquisition and (i) Net Profits, Net Losses, gross income, nonrecourse
deductions and items thereof computed for the portion of the year ending as of
the end of the day on the date of the acquisition shall be allocated among the
Members without regard to such acquisition, and (ii) Net Profits, Net Losses,
gross income, nonrecourse deductions and items thereof computed for the portion
of the year commencing on the day following the date of the acquisition shall be
allocated among the Members taking into account such acquisition. For purposes
of determining the date on which the acquisition occurs, the LLC may make use of
any convention allowable under Section 706(d) of the Code.

                                  ARTICLE VI

     6.01 Management of the LLC. Subject to the provisions of this Agreement,
          ---------------------
the overall management and control of the business and affairs of the LLC shall
be vested in the Directors (each of whom shall be a "manager" of the LLC within
the meaning of the Act), acting collectively as the board of directors (the
"Board of Directors") of the LLC in the manner provided herein, which Board of
Directors (i) may exercise all of the powers of the LLC except as otherwise
provided by law or this Agreement, and (ii) shall make all decisions and
authorize all actions taken by the LLC. The Board of Directors may delegate such
of its rights, powers and authority as it may determine to be necessary or
appropriate to one or more officers of the LLC. No Member shall have any right,
power or authority to act for or on behalf of the LLC, to do any act that would
be binding on the LLC, or to incur any expenditures on behalf of the LLC.
Decisions or actions taken by the Board of Directors in accordance with this
Agreement shall constitute decisions or actions by the LLC and shall be binding
on each Member, Director, officer and employee of the LLC. All management and
other responsibilities not specifically reserved to the Members in this
Agreement shall be vested in the Board of Directors, and the Members shall have
no voting rights except as specifically provided in this Agreement.

     Specifically, but not by way of limitation, but subject to all other
provisions of this Agreement, the Board of Directors shall be authorized in the
name of and on behalf of the LLC, or in its own name and on its own behalf, as
appropriate, to do all things necessary or appropriate, to carry on the business
and purposes of the LLC, including without limitation the following:

                                      -11-
<PAGE>

     (i)    to engage in any kind of activity and to perform and carry out
contracts of any kind necessary to, or in connection with, or incidental to the
accomplishment of the purposes of the LLC;

     (ii)   to hire or employ such agents, employees, managers, accountants,
attorneys, consultants, custodians, subcustodians, and other persons necessary
or appropriate to carry out the business and operations of the LLC, and to pay
fees, expenses, salaries, wages and other compensation to such persons;

     (iii)  to pay, extend, renew, modify, adjust, submit to arbitration,
prosecute, defend or compromise, upon such terms as it may determine and upon
such evidence as it may deem sufficient, any obligation, suit, liability, cause
of action or claim, including taxes, either in favor of or against the LLC;

     (iv)   to determine the appropriate accounting method or methods to be used
by the LLC;

     (v)    to cause the LLC to make or revoke any of the elections referred to
in Sections 108, 704, 709, 754 or 1017 of the Code or any similar provisions
enacted in lieu thereof, or in any other Section of the Code;

     (vi)   to establish and maintain reserves for such purposes and in such
amounts as it deems appropriate from time to time and to pay all organizational
expenses and general and administrative expenses of the LLC;

     (vii)  to pay any and all fees and to make any and all expenditures which
it, in its sole discretion, deems necessary or appropriate in connection with
the organization of the LLC, the management of the affairs of the LLC, and the
carrying out of its obligations and responsibilities under this Agreement,
including, without limitation, fees, reimbursements and expenditures payable to
a Member or Director or their respective Affiliates;

     (viii) to exercise all powers and authority granted by the Act to managers,
except as otherwise provided in this Agreement and to cause the LLC and its
properties and assets to be maintained and operated in such manner as the
Directors may determine, subject, however, to obligations imposed by applicable
laws or by any mortgage or security interest encumbering the LLC and such
properties and assets from time to time, and by any lease, rental agreement or
other agreement pertaining thereto;

     (ix)   to cause to be paid any and all taxes, charges and assessments that
may be levied, assessed or imposed upon any of the assets of the LLC, unless the
same are contested by the Directors; and

     (x)    to perform any other act which the Board of Directors may deem
necessary, convenient or desirable for the LLC or the conduct of its business.

     6.02 Board of Directors.
          ------------------

          (a)  The number of Directors which shall constitute the whole Board of
Directors shall be three, of whom one shall be designated by Aspen, initially
Neal Vitale; one shall be designated by Synapse, initially Michael Loeb; and one
shall be designated jointly by Aspen and Synapse, initially, Jeffrey Gilfix.
Such Directors may, but need not, be Members of the LLC. Each person designated
to serve as a Director hereunder shall execute this Agreement, or a counterpart
hereof or amendment hereto, or other writing pursuant to which such person (i)
agrees to be a party to and bound by this Agreement, and (ii) agrees to perform
the duties of a Director hereunder.

          (b)  Any Director may be removed at any time, with or without cause,
by the Member or Members designating such Director pursuant to Section 6.02(a)
by delivering written notice of such removal to each of the other Members. Such
removal shall be effective upon the giving of the notice, unless such notice is
specified to be effective at some other time or upon the occurrence of some
other event. Any Director who has ceased to serve in such capacity for any
reason may be replaced by the Member or Members which designated such Director
pursuant to Section 6.02(a), by designating a replacement Director, as
appropriate, in a written notice given to each of the other Members. Such
designation of a replacement Representative shall be effective upon the giving
of the notice, unless such notice is specified to be effective at some other
time or upon the occurrence of some other event.

          (c)  Any Director may resign by delivering a written resignation to
the LLC at its principal office. Such resignation shall be effective upon
receipt unless it is specified to be effective at some other time or upon the
happening of some other event.

          (d)  Regular meetings of the Board of Directors may be held without
notice at such time and place, either within or without the State of Delaware,
as shall be determined from time to time by the Board of Directors.

          (e)  Special meetings of the Board of Directors may be called by any
Director and held at any time and place, within or without the State of
Delaware, designated by the Director calling such meeting.

          (f)  Notice of any special meeting of the Board of Directors shall be
given to each Director by an officer of the LLC or by the Director calling such
meeting. Notice shall be duly given to each Director (i) by giving notice to
such Director in person or by telephone at least 48 hours in advance of the
meeting, (ii) by sending a facsimile transmission, or delivering written notice
by hand, to his last known business or home address at least 48 hours in advance
of the meeting, or (iii) by mailing written notice to his last known business or
home address at least four days in advance of the meeting. A notice or waiver of
notice of a meeting of the Board of Directors need not specify the purposes of
the meeting.

          (g)  Directors or any members of any committee designated by the Board
of Directors may participate in a meeting of the Board of Directors or such
committee by means of conference telephone or similar communications equipment
by means of which all persons

                                      -13-
<PAGE>

participating in the meeting can hear each other, and participation by such
means shall constitute presence in person at such meeting.

          (h)  At any meeting of the Board of Directors, the affirmative vote of
a majority of the Directors, which shall include the Director designated by
Aspen and the Director designated by Synapse, shall be necessary and sufficient
for the taking of any action, unless a different requirement is imposed by non-
waivable provisions of applicable law, by the Certificate or by this Agreement.

          (i)  Any action required or permitted to be taken at any meeting of
the Board of Directors or of any committee of the Board of Directors may be
taken without a meeting, if the same Directors necessary to authorize an action
at an meeting pursuant to Section 6.02(h) above, consent to the action in
writing, and the written consents are filed with the minutes of proceedings of
the Board of Directors or such committee.

          (j)  Each Director shall be required to devote only such time to the
business and affairs of the LLC as may be reasonably necessary for the
performance of his or her duties hereunder, and no Director shall be required to
devote all or any specified portion of his or her time to the business and
affairs of the LLC. Directors may be paid such reimbursement for expenses of
attendance at meetings and other compensation for services as the Board of
Directors may from time to time determine.

     6.03 Binding the LLC. The signature of each of the Aspen designated
          ---------------
Director and the Synapse designated Director, or of any officer of the LLC if
such authority is so designated by the Board of Directors, on any agreement,
contract, instrument or other document shall be sufficient to bind the LLC in
respect thereof and conclusively evidence the authority of such Directors and
the LLC with respect thereto, and no third party need look to any other evidence
or require the joinder or consent of any other party.

     6.04 Contracts with Members. The LLC may engage in business with, or enter
          ----------------------
into one or more agreements, leases, contracts or other arrangements for the
furnishing to or by the LLC of goods, services or space with any Member or
Affiliate of a Member or of the Director, and may pay compensation in connection
with such business, goods, services or space, provided in each case the amounts
payable thereunder are reasonably comparable to those which would be payable to
unaffiliated persons under similar agreements, and if the Board of Directors
determines in good faith that such amounts are so comparable, such determination
shall be conclusive absent manifest error.

     6.05 Exculpation and Indemnification; Fiduciary Duty.
          -----------------------------------------------

          (a)  The Members' respective obligations to each other are limited to
the express obligations described in this Agreement, which obligations the
Members shall carry out with ordinary prudence and in a manner characteristic of
business persons in similar circumstances. No Member shall be a fiduciary of or
have any fiduciary obligations to the other Members in connection with the LLC
or this Agreement or such Member's performance of its obligations under this
Agreement, and each Member hereby waives to the fullest extent

                                      -14-
<PAGE>

permitted by applicable law any rights it may have to claim any breach of
fiduciary obligation under this Agreement or in connection with the LLC.

          (b)  No Director or its Affiliates shall have any liability to the LLC
or to any Member for any loss suffered by the LLC which arises out of any action
or inaction of any Director or its Affiliates if such Director or its
Affiliates, as the case may be, in good faith, determined that such course of
conduct was within the scope of its authority under this Agreement and such
course of conduct did not constitute gross negligence or willful misconduct of
such Director or its Affiliates.

          (c)  Each Director and its Affiliates shall be indemnified by the LLC
against any losses, judgments, liabilities, expenses and amounts paid in
settlement of any claims sustained by it with respect to actions taken by such
Director or its Affiliates on behalf of the LLC, provided that no
indemnification shall be provided for any person with respect to any matter as
to which he or she shall have been adjudicated in any proceeding (i) not to have
acted within the scope of its authority under this Agreement, or (ii) to have
acted in a manner constituting gross negligence or willful misconduct.

     Without limiting the foregoing, the LLC shall cause such indemnification to
include payment by the LLC of expenses incurred in defending a civil or criminal
action or proceeding in advance of the final disposition of such action or
proceeding, upon receipt of an undertaking by the person indemnified to repay
such payment if he or she shall be adjudicated not to be entitled to
indemnification under this Section 6.05, which undertaking may be accepted
without reference to the financial ability of such person to make repayment. Any
indemnification to be provided hereunder shall be provided although the person
to be indemnified is no longer a Director or an Affiliate of a Director.

          (d)  Any indemnity under this Section 6.05 shall be paid from, and
only to the extent of, LLC assets, and no Member shall have any personal
liability on account thereof.

     6.06 Other Activities. The Members and any Affiliates of any of them, may
          ----------------
engage in and possess interests in other business ventures and investment
opportunities of every kind and description, independently or with others,
including serving as directors, officers, stockholders, managers, members and
general or limited partners of corporations, partnerships or other limited
liability companies with purposes similar to or the same as those of the LLC.
Neither the LLC nor any other Member shall have any rights in or to such
ventures or opportunities or the income or profits therefrom.

     6.07 LLC Services. At the request of Synapse, the LLC shall make the
          ------------
services of its officers available to Synapse for the purpose of performing
accounting, administrative, research, consulting, advisory and related services
to Synapse. For making its officers available to Synapse, Synapse shall pay the
LLC a fee to be mutually agreed upon by the LLC and Synapse.

          -------
of Directors shall furnish all Members with such information as may be needed to
enable the Members to file their federal income tax returns and any required
state income tax return. The cost of all such reporting shall be paid by the LLC
as an LLC expense.

     7.03 Bank Accounts. The Board of Directors shall be responsible for causing

one or more bank or money market accounts, which accounts shall be used for the
payment of the expenditures incurred in connection with the business of the LLC,

short-term investments, including securities issued or fully guaranteed by
United States government agencies, certificates of deposit of banks, money
market funds, interest-bearing time deposits in banks and thrift institutions
and such other similar investments as the Board of Directors may approve. All
such amounts shall be and remain the property of the LLC, and shall be received,
held and disbursed by the Board of Directors for the purposes specified in this
Agreement. There shall not be deposited in any of said accounts any funds other
than funds belonging to the LLC, and no other funds shall in any way be
commingled with such funds. Withdrawals from any LLC bank or similar account
shall be made and other activity conducted on such signature or signatures as

     8.01 General Restrictions on Transfer of Interests by Members.
          --------------------------------------------------------

          (a)  No Member may Transfer his, her or its interest in the LLC
(including without limitation, by resignation as a member of the LLC) unless the
Board of Directors shall have previously approved such Transfer in writing, the
granting or denying of which approval shall be in the Board of Director's
absolute discretion, provided, however, that (i) a successor-in-interest by
merger, consolidation, operation of law or otherwise of the entire business of
either Aspen or Synapse, acquires all interests of such party under this
Agreement without the approval of the Board of Directors and (ii) any transfer
by Synapse or Aspen of its respective interest in the LLC to any lending
institution(s) providing loan facilities to Synapse or Aspen, as the case may
be, or such Member's Affiliates shall not require approval of the Board of
Directors.

          No assignment of the interest of a Member shall be made if, in the
opinion of counsel to the LLC, such assignment (i) may not be effected without
registration under the Securities Act, (ii) would result in the violation of any
applicable state securities laws, (iii) unless approved by the Board of
Directors, would result in a termination of the LLC under Section 708 of the
Code, (iv) unless approved by the Board of Directors, would result in the
treatment of the LLC as an association taxable as a corporation or as a
"publicly-traded limited partnership" for tax purposes or (v) would cause the
LLC to be required to register as an investment company, as such term is defined
in the Investment Company Act of 1940, as amended. The LLC shall not be required
to recognize any such assignment until the instrument conveying such interest
has been delivered to the Board of Directors for recordation on the books of the
LLC. Unless an assignee becomes a Member in accordance with the provisions of
Section 8.01(b), it shall not be entitled to any of the rights granted to a
Member hereunder, other than the right to receive all or part of the share of
the Gross Income, Net Profits, Net Losses and Nonrecourse Deductions (and items
thereof), its distributions of cash or property or returns of capital to which
its assignor would otherwise be entitled in respect of the interest assigned.

          (b)  An assignee of the interest of a Member, or any portion thereof,
shall become a Member entitled to all the rights of a Member if, and only if:

               (i)  the assignor gives the assignee such right;

               (ii) the Board of Directors approves such substitution, the
     granting or denying of which consent shall be in the Board of Director's
     absolute discretion,

                                      -17-
<PAGE>

     provided, however, that such consent shall not be required for any transfer
     made pursuant to Sections 8.01(a)(i) or 8.01(a)(ii);

               (iii) the assignee pays to the LLC all costs and expenses
     incurred in connection with such substitution, including specifically,
     without limitation, costs incurred in the review and processing of the
     assignment and in amending the LLC's then current Certificate and/or
     Limited Liability Company Agreement, if required; and

               (iv)  the assignee executes and delivers an Amendment to this
     Agreement (and to the Certificate, if required), which Amendment shall be
     executed by the Board of Directors and such assignee, and such other
     instruments, in form and substance satisfactory to the Board of Directors
     as may be necessary, appropriate or desirable to effect such substitution
     and to confirm the agreement of the assignee to be bound by the terms and
     provisions of this Agreement.

          (c)  The LLC and the Board of Directors shall be entitled to treat the
record owner of any LLC interest as the absolute owner thereof in all respects,
and shall incur no liability for distributions of cash or other property made in
good faith to such owner until such time as a written assignment of such
interest has been received and accepted by the Board of Directors and recorded
on the books of the LLC. The Board of Directors may refuse to accept an
assignment until the end of the next successive quarterly accounting period. In
no event shall any membership interest, or any portion thereof, be sold,
transferred or assigned to a minor or incompetent, and any such attempted sale,
transfer or assignment shall be void and ineffectual and shall not bind the LLC
or the Board of Directors.

     8.02 Restrictions as to Certain Matters. Every Transfer of an interest of a
          ----------------------------------
Member of the LLC permitted by this Article VIII shall be subject to the
following restrictions:

          (a)  No Transfer of any interest in the LLC may be made if such
Transfer would cause or result in a breach of any agreement binding upon the LLC
or of then applicable rules and regulations of any governmental authority having
jurisdiction over such Transfer.

          (b)  Any person who acquires in any manner whatsoever an interest (or
any part thereof) in the LLC, whether or not such person has accepted and
assumed in writing the terms and provisions of this Agreement or been admitted
into the LLC as a Member as provided in Section 8.01(b), shall be deemed, by
acceptance of the acquisition thereof, to have agreed to be subject to and bound
by all of the obligations of this Agreement with respect to such interest and
shall be subject to the provisions of this Agreement with respect to any
subsequent Transfer of such interest.

          (c)  Any Transfer in contravention of any of the provisions of this

deemed to be a Member for any purpose. In the event any Member shall at any time
Transfer an interest in the LLC in contravention of any of the provisions of

remedies at law and equity, be entitled to a decree or order restraining and
enjoining such transaction, and the offending Member shall not plead in defense
thereto that there would be an adequate remedy at law; it being expressly hereby
acknowledged and agreed that damages at law would be an inadequate remedy for a
breach or threatened breach of the provisions of this Agreement concerning such
transactions.

                                  ----------

                          DISSOLUTION AND LIQUIDATION
                          ---------------------------

     9.01 Events Causing Dissolution. The LLC shall be dissolved and its affairs
          --------------------------
wound up upon:

          (a)  The sale or other disposition of all or substantially all of the
assets of the LLC, unless the disposition is a transfer of assets of the LLC in
return for consideration other than cash and the Board of Directors determines
not to distribute all or substantially all of such non-cash items to the
Members;

          (b)  The election to dissolve the LLC made in writing by the Board of
Directors;

          (c)  Any consolidation or merger of the LLC with or into any entity
following which the LLC is not the resulting or surviving entity;

          (d)  Upon Synapse's written election, upon the termination of the
Sales Representation Agreement between the LLC and NewSub Special Services,
Inc., dated as of the date hereof;

          (e)  Upon Aspen's written election, upon the termination of the Supply
Agreement between the LLC and Aspen, dated as of the date hereof; or

          (f)  Upon the occurrence of an event specified under the laws of the
State of Delaware as one effecting dissolution, except that where, under the
terms of this Agreement or the Act, the LLC is not to terminate, then the LLC
shall immediately be reconstituted and reformed on all the applicable terms,
conditions, and provisions of this Agreement. The LLC shall not be dissolved
upon the death, insanity, retirement, resignation, expulsion, bankruptcy,
dissolution or occurrence of any other event which terminates the membership of
a Member.

     9.02 Procedures on Dissolution. Dissolution of the LLC shall be effective
          -------------------------
on the day on which occurs the event giving rise to the dissolution, but the LLC
shall not terminate until the Certificate shall have been cancelled and the
assets of the LLC shall have been distributed as provided herein.
Notwithstanding the dissolution of the LLC, prior to the termination of the LLC,
as aforesaid, the business of the LLC and the affairs of the Members, as such,
shall continue to be governed by this Agreement. The Board of Directors or a
liquidator appointed

                                      -19-
<PAGE>

with the consent of the Members, shall liquidate the assets of the LLC, apply
and distribute the proceeds thereof as contemplated by this Agreement and cause
the cancellation of the Certificate.

     9.03  Distributions Upon Liquidation.
           ------------------------------

           (a)  After payment of liabilities owing to creditors, the Board of
Directors or a liquidator appointed with the consent of the Members shall set up
such reserves as it deems reasonably necessary for any contingent or unforeseen
liabilities or obligations of the LLC. Said reserves may be paid over by Board
of Directors or such liquidator to a bank, to be held in escrow for the purpose
of paying any such contingent or unforeseen liabilities or obligations and, at
the expiration of such period as the Board of Directors or such liquidator may
deem advisable, such reserves shall be distributed to the Members or their
assigns in the manner set forth in paragraph (b) below.

           (b)  After paying such liabilities and providing for such reserves,
the Board of Directors or liquidator appointed with the consent of the Members
shall cause the remaining net assets of the LLC to be distributed to and among
the Members in proportion to and to the extent of their positive Capital Account
balances (after such balances have been adjusted to reflect the allocation of
Net Profits, Net Losses and items thereof arising from such event pursuant to
Sections 5.01 and 5.02). In the event that any part of such net assets consists
of notes or accounts receivable or other non-cash assets, the Board of Directors
or liquidator may take whatever steps it deems appropriate to convert such
assets into cash or into any other form which would facilitate the distribution
thereof. If any assets of the LLC are to be distributed in kind, such assets
shall be distributed on the basis of their fair market value net of any
liabilities. Notwithstanding the foregoing, the Members agree that any and all
trademarks developed pursuant to the business of the LLC, and all the good will
associated thereto, shall be assigned to Synapse or its designated Affiliate
upon the occurrence of any event described in Section 9.01.

           --------------------------
considered separable. To the extent that any provision of this Agreement is
prohibited or ineffective under the Act, this Agreement shall be considered
amended to the smallest degree possible in order to make the Agreement effective

           ----------

           (i)  By the Board of Directors, without the consent or approval of
     any of the Members, and any such amendment may include, without limitation,
     an amendment providing for capital contributions from, distributions to,
     and allocations of Net Profits and Net Losses (and items thereof) to one or
     more additional classes of Members; provided that (x) no such amendment
     shall increase the liability of or increase the obligations of or adversely
     affect the interest of, any Member without the specific approval of such
     Member; and (y) if any provision of this Agreement provides for the
     approval or consent of a greater number of Members or of Members holding a
     higher percentage of the total Percentage Interests of the Members, any
     amendment effectuated pursuant to such provision, and any amendment to such
     provision, shall require the approval or consent of such greater number of
     Members or of Members holding such higher percentage of Percentage
     Interests.

           (ii) Without limitation of clause (i) above, by the Board of
     Directors acting alone, to modify appropriate provisions of this Agreement
     if the LLC is advised at any time by its legal counsel that the allocations
     of profits and losses and similar items provided for in Article V hereof
     are unlikely to be respected for federal income tax purposes, either
     because of the promulgation and adoption of Treasury Regulations under

                                      -21-
<PAGE>

     Code Section 704 or other developments in applicable law. In making any
     such amendment, the Board of Directors shall use its best efforts to effect
     as little change in the economic and tax arrangements among the Members as
     it shall determine in its sole discretion to be necessary to provide for
     allocations of profits and losses to the Members which it believes will be
     respected for federal income tax purposes. No such amendment shall give
     rise to any claim or cause of action by any Member or the LLC.

           (iii) Without limitation of clause (i) above, by the Board of
     Directors acting alone, to implement the provisions of Sections 8.01 and
     8.02.

     10.9  Entire Agreement. This Agreement embodies the entire agreement and
           ----------------
understanding between the parties hereto with respect to the subject matter
hereof and supersedes all prior agreements and understandings relating to such
subject matter. The Members and Directors hereby agree that each Member and each
Director shall be entitled to rely on the provisions of this Agreement, and no
Member or Director shall be liable to the LLC or any other Member or Director
for any action or refusal to act taken in good faith reliance on the terms of
this Agreement.

     10.10 Waiver of Partition. Each Member agrees that irreparable damage
           -------------------
would be done to the LLC if any Member brought an action in court to dissolve
the LLC. Accordingly, each Member agrees that he, she or it shall not, either
directly or indirectly, take any action to require partition or appraisal of the
LLC or of any of the assets or properties of the LLC, and notwithstanding any
provisions of this Agreement to the contrary, each Member (and his, her or its
successors and assigns) accepts the provisions of the Agreement as his, her or
its sole entitlement on termination, dissolution and/or liquidation of the LLC
and hereby irrevocably waives any and all right to maintain any action for
partition or to compel any sale or other liquidation with respect to his, her or
its interest, in or with respect to, any assets or properties of the LLC. Each
Member agrees that he, she or it will not petition a court for the dissolution,
termination or liquidation of the LLC.

     10.11 Confidentiality.
           ---------------

     (a)   Unless the Members mutually agree otherwise, each Member and each
Director shall hold in strict confidence the terms of this Agreement and any
information it receives hereunder or in connection herewith or otherwise in
connection with the conduct of the LLC's business and affairs regarding the LLC
or the business, affairs, operations or assets of the LLC or of any other Member
(or its Affiliates), whether such information is received from the LLC, a Member

statement from the disclosing Party that it constitutes "Proprietary
Information" (such information hereinafter also referred to as "Proprietary
Information"); provided, however, that a Member shall not be liable for
disclosing information disclosed orally or visually to it prior to such time as
such Member receives such a statement from the disclosing party. During and

                                      -22-
<PAGE>

after the term of this Agreement, the Members shall not disclose the Proprietary
Information except to those of it's agents, employees, subcontractors and
consultants to whom it is necessary in order to carry on its business pursuant
to this Agreement. During and after the term of this Agreement, the Members,
their agents, employees, subcontrators and consultants shall not use the
Proprietary Information for any purpose other than in connection with the
business of the LLC. The Members shall, at their own expense, return any
Proprietary Information as soon as practicable after the date of termination or

otherwise required by law, after giving the Members advance notice, if possible,
of such required disclosure and after assisting any other Member in its
reasonable efforts to prevent or limit such disclosure.
