Manager or any such Management Committee member or Member of the Company's
property, including, but not limited to, confidential or proprietary information
of the Company entrusted to the Person as a result of that Person's status as a

the Company. Neither the Company nor any Member shall have any right, by virtue
of this Operating Agreement, to share or participate in such other permitted

and Other Agents.

      (a) General. The Company shall fully indemnify in all circumstances to the
extent not prohibited by law any person made, or threatened to be made, a party
to an action or proceeding whether civil or criminal, including an
investigative, administrative or legislative proceeding, including an action by
or in the right of the Company or any corporation, partnership, joint venture,
limited liability company, trust, employee benefit plan or other enterprise, of
any type or kind, domestic or foreign, by reason of that fact that such person,
his testator or intestate, is or was a Manager or member of the Management
Committee, or with the approval of a majority of the members of the Management
Committee is or was serving at the request of the Company, in any corporation,
partnership, joint venture, limited liability company, trust, employee benefit
plan or other enterprise of any type or kind, domestic or foreign, as a
director, officer or in any other capacity, against any and all judgments,
fines, amounts paid in settlement and expenses, including attorneys' fees,
actually or reasonably incurred as a result of or in connection with any such
action or proceeding or related appeal; provided, however, that no
indemnification shall be made to or on behalf of any Manager or member of the
Management Committee if a judgment or other final adjudication adverse to him
establishes that his acts were committed in bad faith or were the result of
active and deliberate dishonesty and were material to the cause of action so
adjudicated, or that he personally gained in fact a financial profit or other
advantage to which he was not legally entitled; and, the Company shall pay
expenses incurred by or on behalf of such a person in defending such a civil or
criminal action or proceeding (including appeals) in advance of the final
disposition of such action or proceeding promptly upon receipt by the

<PAGE>   18

Company, from time to time, of a written demand of such person for such
advancement, together with an undertaking by or on behalf of such person to
repay any expenses so advanced to the extent that the person receiving the
advancement is ultimately found not to be entitled to indemnification for such
expenses; and the right to indemnification and advancement of defense expenses
granted by or pursuant to this Section 5.11 (i) shall not limit or exclude, but
shall be in addition to, any other rights which may be granted by or pursuant to
any statute, certificate of incorporation, by-law, resolution or agreement, (ii)
shall be deemed to constitute a contractual obligation of the Company to any
Manager or member of the Management Committee who serves in such capacity at any
time while this Section 5.11 is in effect, (iii) are intended to be retroactive
and shall be available with respect to events occurring prior to the adoption of
this Section 5.11, and (iv) shall continue to exist after the repeal or
modification hereof with respect to events occurring prior thereto. It is the
intent of this Section 5.11 to require the Company to indemnify the persons
referred to herein for the aforementioned judgments, fines, amounts paid in
settlement and expenses, including attorneys' fees, in each and every
circumstance in which such indemnification could lawfully be permitted by an
express provision, and the indemnification required by this Section 5.11 shall
not be limited by the absence of an express recital of such circumstances.

      (b) Insurance. The Company shall purchase and maintain insurance on behalf
of any person who is or was a Manager, or Management Committee member, and shall
have the power to purchase and maintain insurance on behalf of any person who is
or was an employee or agent of the Company, or is or was serving at the request
of the Company as a member, principal, director, officer, trustee, partner,
fiduciary, employee, or agent of another Entity, pension, or other employee
benefit plan or other enterprise, against any liability asserted against that
person and incurred by that person in any such capacity, or arising out of that
person's status as such, whether or not the Company would have the power to
indemnify that person against such liability under this Section 5.11.

additional Capital Contributions in accordance with this Agreement and with the
Consent of the other Member, the non-contributing Member's Economic Interest
shall be diluted. Dilution shall be based upon the Capital Account balance at
the time additional Capital Contributions are made. A Member's Economic Interest
shall be adjusted proportionally to the relative positive Capital Accounts of
the Members at the time any additional Capital Contributions are made, but
excluding any portion of a Capital Account attributable to a Division.

      (b) Anything to the contrary contained in Section 8.2 notwithstanding, in
the event that the Manager or the Management Committee reasonably determines
that the Company's cash reserves and reasonably anticipated revenues are less
than is needed to satisfy its existing liabilities or its budgeted needs for
capital expenditures and working capital during the succeeding twelve (12)
months, either Member shall be empowered to seek approval from the Members for
additional Capital Contributions, which shall not be unreasonably withheld,
sufficient in the reasonable judgment of the Manager or the Management Committee
to fund the anticipated shortfall.

      (c) Energy East may elect to participate in the Cornell Project and have
it become a part of the Fiber Optic Network and the business and assets of the
Company by making a Capital Contribution equal to fifty percent (50%) of the
capital costs incurred by Telergy to construct and install the Cornell Project.
Energy East may make the election by giving written notice to Telergy at any
time within the one (1) year following the Effective Date. Within fifteen (15)
days of the notice from Energy East, Telergy shall notify Energy East in writing
of the amount of the Capital Contribution to be made, and within the next
fifteen (15) days Energy East shall make its Capital Contribution of cash and
simultaneously therewith, Telergy shall make a Capital Contribution of the
business and assets of the Cornell Project. The cash contributed by Energy East
shall be immediately distributed to Telergy. The Cornell Project shall be
accounted for as part of the business and assets of the Company following these
Capital Contributions by the Members.

      (d) A Participating Member shall make the Capital Contributions necessary
to fund the capital costs for the Segregated Network of a Division.

      8.3 Loans. Telergy shall loan funds to the Company sufficient to install
the fiber cable along the Backbone Network and the Ithaca and Binghamton Spurs.
Telergy may loan funds to the Company to finance costs authorized by the
Company's capital expenditures and/or operating budgets, subject to Section
5.4(a)(vi). All loans by Telergy shall be evidenced by promissory notes given by
the Company, which shall contain an interest rate and maturity date identical to
the terms of the High Yield Note or the MasTec Financing (if either of these
financings were the source of the funds being loaned) and shall require interest
and principal payments which are one business day prior to the corresponding
payment date of the High Yield Note or MasTec Financing. The

<PAGE>   24

promissory notes given by the Company shall be secured by a perfected first lien
against the assets of the Company including the Fiber Optic Network. Prior to
the issuance of the High Yield Note or when MasTec Financing is not available,
any loans from Telergy shall be evidenced by secured demand promissory notes
requiring the payment of Market Interest plus 2%.

      8.4 Capital Accounts.

      (a) A separate Capital Account shall be maintained for each Member in
accordance with the capital accounting rules of Section 704(b) of the Code. The
beginning balance in each Member's Capital Account shall be the amount of such
Member's initial Capital Contribution made pursuant to Section 8.1. Thereafter,
a Member's Capital Account shall be increased by (i) the amount of any
subsequent Capital Contribution to the Company by such Member; (ii) such
Member's distributive share of Net Profit and items in the nature of income or
gain which are allocated pursuant to Section 9.2; and (iii) such other amounts
as may be required for the Capital Account to be determined and maintained in
accordance with the rules of Section 1.704-1(b)(2)(iv) of the Treasury
Regulations (including Section 1.704-1(b)(2)(iv)(g) thereof). A Member's Capital
Account shall be decreased by (i) such Member's distributive share of Net Loss
and items in the nature of loss or deduction allocated pursuant to Section 9.2;
(ii) the amount of cash or the Fair Market Value of any property distributed
from the Company to such Member (reduced by the amount of debt, if any, assumed
by such Member in connection with the distribution); and (iii) such other
amounts as may be required for the Capital Account to be determined and
maintained in accordance with the rules of Section 1.704-1(b)(2)(iv) of the
Treasury Regulations (including Section 1.704-1(b)(2)(iv)(g) thereof). It is the
parties' specific intent that Capital Accounts shall be maintained in accordance
with the capital account maintenance rules contained in section 704(b) of the
Code, including the Treasury Regulations thereunder, and this Section 8.4(a)
shall be construed and applied to achieve such result.

      (b) Upon liquidation of the Company (or any Member's Membership Interest),
liquidating distributions will be made in accordance with the positive Capital
Account balances of the Members in accordance with Section 12.3 after taking
into account all Capital Account adjustments for the Company's Fiscal Year
during which the liquidation occurs. The Company may offset damages for breach
of this Operating Agreement by a Member whose interest is liquidated (either
upon the withdrawal of the Member or the liquidation of the Company) against any
other amount otherwise distributable to such Member.

      8.5 Withdrawal or Reduction of Members' Contributions to Capital.

      (a) A Member shall not receive out of the Company's property any part of
its Capital Contribution until all liabilities of the Company have been paid.

      (b) A Member, irrespective of the nature of its Capital Contribution, has
only the right to receive cash in return for its Capital Contribution.

<PAGE>   25

      (c) A Member may not withdraw from the Company or assign its Membership
Interest or Economic Interest prior to the dissolution and winding up of the
Company, except as provided in Article X. In no event shall a Member who
voluntarily or involuntarily withdraws from the Company be entitled as a
consequence of such withdrawal to receive the benefits of Section 606 of the
Act.

                                   ARTICLE IX

                     ALLOCATIONS, INCOME TAX, DISTRIBUTIONS,
                             ELECTIONS, AND REPORTS

      9.1 Allocations of Profits and Losses from Operations.

      (a) The Net Profits and Net Losses of the Company for each Fiscal Year
shall be allocated between the Members in proportion to the Economic Interests
held by Members.

      (b) The items of income, gain, and loss and deduction attributable to a
Division shall be allocated to the Participating Member which funded the capital
costs of the Division.

      9.2 Special Allocations to Capital Accounts and Certain Other Income Tax
Allocations. Notwithstanding Section 9.1 hereof:

      (a) In the event any Member unexpectedly receives any adjustments,
allocations, or distributions described in Sections 1.704-1(b)(2)(ii)(d)(4),
(5), or (6) of the Treasury Regulations, which create or increase a Deficit
Capital Account of such Member, then items of Company income and gain
(consisting of a pro rata portion of each item of Company income, including
gross income, and gain for such taxable year and, if necessary, for subsequent
years) shall be specially allocated to such Member in an amount and manner
sufficient to eliminate, to the extent required by the Treasury Regulations, the
Deficit Capital Account so created as quickly as possible. It is the parties'
intent that this Section 9.02(a) be interpreted to comply with the alternate
test for economic effect set forth in Section 1.704-1(b)(2)(ii)(d) of the
Treasury Regulations.

      (b) In the event any Member would have a Deficit Capital Account at the
end of any Company taxable year which is in excess of the sum of any amount that
such Member is obligated to restore to the Company under Section
1.704-1(b)(2)(ii)(c) of the Treasury Regulations and such Member's share of
minimum gain as defined in Section 1.704-2(g)(1) of the Treasury Regulations
(which is also treated as an obligation to restore in accordance with Section
1.704-1(b)(2)(ii)(d) of the Treasury Regulations), the Capital Account of such
Member shall be specially credited with items of Company income (including gross
income) and gain in the amount of such excess as quickly as possible.

<PAGE>   26

      (c) Notwithstanding any other provision of this Section 9.2, if there is a
net decrease in the Company's minimum gain as defined in Treasury Regulation
Section 1.704-2(d) during a taxable year of the Company, then the Capital
Accounts of each Member shall be allocated items of income (including gross
income) and gain for such taxable year (and if necessary for subsequent years)
equal to that Member's share of the net decrease in Company minimum gain. This
Section 9.2(c) is intended to comply with the minimum gain charge-back
requirement of Section 1.704-2 of the Treasury Regulations and shall be
interpreted consistently therewith. If in any taxable year that the Company has
a net decrease in the Company's minimum gain, if the minimum gain charge-back
requirement would cause a distortion in the economic arrangement among the
Members and it is not expected that the Company will have sufficient other
income to correct that distortion, the Tax Matters Member may in its discretion
(and shall, if requested to do so by a Member) seek to have the Internal Revenue
Service waive the minimum gain charge-back requirement in accordance with
Treasury Regulation Section 1.704-2(f)(4).

      (d) Items of Company loss, deduction, and expenditures described in
Section 705(a)(2)(B) of the Code that are attributable to any non-recourse debt
of the Company and are characterized as partner (Member) non-recourse deductions
under Section 1.704-2(i) of the Treasury Regulations shall be allocated to the
Members' Capital Accounts in accordance with said Section 1.704-2(i) of the
Treasury Regulations.

      (e) Beginning in the first taxable year in which there are allocations of
"nonrecourse deductions" (as described in Section 1.704-2(b) of the Treasury
Regulations), such deductions shall be allocated to the Members in the same
manner as Net Profit or Net Loss is allocated for such period.

      (f) In accordance with Section 704(c)(1)(A) of the Code and Section
1.704(b)(2)(i)(iv) of the Treasury Regulations, if a Member contributes property
with a fair market value that differs from its adjusted basis at the time of
contribution, income, gain, loss, and deductions with respect to the property
shall, solely for federal income tax purposes (and not for Capital Account
purposes), be allocated among the Members so as to take account of any variation
between the adjusted basis of such property to the Company and its fair market
value at the time of contribution.

      (g) Any credit or charge to the Capital Accounts of the Members pursuant
to Sections 9.2 (a), (b), (c), (d), and/or (e) hereof shall be taken into
account in computing subsequent allocations of Net Profits and Net Losses
pursuant to Section 9.1, so that the net amount of any items charged or credited
to Capital Accounts pursuant to Sections 9.1 and 9.2 (a), (b), (c), (d), and/or
(e) shall to the extent possible, be equal to the net amount that would have
been allocated to the Capital Account of each Member pursuant to the provisions
of this Article IX if the special allocations required by Sections 9.2 (a), (b),
(c), (d), and/or (e) hereof had not occurred.

<PAGE>   27
      9.3 Distributions. All distributions of Distributable Cash and property
shall be made to the Members in proportion to the percentages of their Economic
Interests on the record date of such distribution, except that the Distributable
Cash of a Division shall be paid to the Participating Member which funded the
capital costs of the Division. Except as provided in Section 9.4 and except as
restricted by a majority of the members of the Management Committee as provided
in Section 5.4(a)(v), all Distributable Cash shall be paid to the Members
periodically throughout the Fiscal Year during which it was earned or otherwise
received by the Company. The final payment of Distributable Cash determined for
each Fiscal Year shall be no later than March 30 following the end of such
Fiscal Year. The Management Committee shall use its best efforts to authorize
payments of Distributable Cash at such times as to enable each Member to pay its
federal and state income taxes determined at the highest effective tax rate
attributable to its share of the Company's taxable income. Except as provided in
Section 9.4, all distributions of property shall be made at such time as
determined by a majority of the members of the Management Committee as provided
in Section 5.4(a)(v).

      9.4 Limitation Upon Distributions. No distribution shall be declared and
paid if, in the determination of a majority of the members of the Management
Committee after giving effect to the distribution:

      (a) the Company would not able to pay its debts as they become due in the
usual course of business; or

      (b) all liabilities of the Company, other than liabilities for which the
recourse of creditors is limited to specified property of the Company, would
exceed the fair value of the Company's assets, except that the fair value of
property that is subject to a liability for which the recourse of creditors is
limited shall be included in the Company's assets only to the extent the fair
value of that property exceeds that liability.

As contemplated by Section 508 of the Act, the members of the Management
Committee may base the determination under this Section on either:

      (a) financial statements prepared on the basis of accounting practices and
principles that are reasonable under the circumstances; or

      (b) a fair valuation or other method that is reasonable under the
circumstances.

The members of the Management Committee shall make their determination under
this Section and authorize any distribution under Section 9.3 in accordance with
the standards of Section 508 of the Act.

      9.5 Accounting Principles. The Net Profits and Net Losses of the Company
shall be determined as provided in Section 1.37 using the accrual method of
accounting applied on a consistent basis.

      9.6 Interest On Capital Contributions. No Member shall be entitled to
interest on

<PAGE>   28

its Capital Contribution, except as otherwise specifically provided for in this
Agreement.

      9.7 Accounting Period. The Company's accounting period shall be the Fiscal
Year.

      9.8 Books of Account and Records. At the expense of the Company, the
Manager shall maintain and preserve records and accounts of all operations and
expenditures of the Company for the length of time thereafter as may be required
to meet the records retention requirements of any taxing or regulatory body
having direct or indirect jurisdiction over all accounts, books, and other
relevant Company documents. The books of account shall accurately reflect all
transactions and other matters relating to the Company's business in such detail
and completeness as is customary and usual for businesses of the type engaged in
by the Company. As contemplated by Section 1102 of the Act, at a minimum the
Company shall keep at its principal place of business the following records and
shall be prepared to make such records available to regulatory agencies as may
be required by law:

      (a) a current list and a past list with the full names and last known
mailing addresses of each Member and each member of the Management Committee;

      (b) a copy of the Articles of Organization and all amendments thereto;

      (c) copies of the Company's federal, state, and local income tax returns
and financial statements for the six most recent years;

      (d) copies of the current and all prior Operating Agreements of the
Company, including all amendments thereto;

      (e) a writing setting forth the amount of cash and the Fair Market Value
of property or services contributed by each Member;

      (f) copies of any separate agreements pertaining to a Member's obligation
to contribute cash, property, or services; and

      (g) minutes of meetings of the Members, the Management Committee, or the
Manager and any written consents obtained from Members, the Management
Committee, or the Manager in lieu of a meeting; and

      (h) such other records as the Management Committee deems appropriate.

Upon reasonable advance notice to the Manager, each Member shall have the right,
during ordinary business hours, to inspect and copy such Company documents at
the requesting Member's expense, subject to the Confidentiality provision in
Section 17.16; provided, however, that the Manager shall be authorized, in its
discretion, to withhold from or to restrict or condition the access of one or
more Members to information of the Company

<PAGE>   29

as and to the extent contemplated by Section 1102 (c) of the Act.

      9.9 Returns and other Elections. The Manager shall cause the preparation
and timely filing of all tax returns required to be filed by the Company
pursuant to the Code and all other tax returns deemed necessary and required in
each jurisdiction in which the Company does business. Copies of such returns, or
pertinent information therefrom, shall be furnished to the Members within a
reasonable time after the end of the Company's Fiscal Year. All elections
permitted to be made by the Company under federal or state laws shall be made by
the Tax Matters Member, provided that the Tax Matters Member shall make any tax
election requested by the Management Committee or by a unanimous vote or Consent
of the Members.

                                    ARTICLE X

                                 TRANSFERABILITY

      10.1 General. Except as otherwise specifically provided in this Article X,
without the unanimous vote or Consent of the Members, a Member shall not have
the right to sell, assign, transfer, exchange, or otherwise transfer
(collectively, "Transfer"), whether or not by operation of law, all or any part
of its Membership Interest.

      Notwithstanding the foregoing, a unanimous vote or Consent of the Members
shall not be required in order for a Member to Transfer all or any part of its
Membership Interest, and it shall be permissible for a Member to Transfer all or
part of its Membership Interest and this Agreement, to any wholly-owned
subsidiary, to any second tier wholly owned subsidiary thereof, or in connection
with any merger or consolidation to which the Member is the surviving and
controlling party. Provided further, in the event of a Transfer by a Member to
any such wholly-owned subsidiary or a Transfer that may occur in connection with
any merger or consolidation where the Member is the surviving and controlling
party, the right of first refusal provisions of Section 10.2 shall not apply.

      Each Member hereby acknowledges the reasonableness of the restrictions on
Transfer of Membership Interests imposed by this Operating Agreement in view of
the Company's purposes and the relationship of the Members. Accordingly, the
restrictions on Transfer contained in this Article X shall be specifically
enforceable.

<PAGE>   30

      10.2 Right-of-First Refusal.

      (a) A Member (the "Selling Member") that desires to sell all of its
Economic Interest in the Company to a qualified third party purchaser shall
obtain from such third party purchaser a bona fide written offer to purchase
such Economic Interest, stating the terms and conditions upon which the purchase
is to be made and the consideration offered therefor. The Selling Member shall
give written notice to the other Member of its intention to sell such interest,
which other Member shall have the right to purchase all (but not less than all)
of the Economic Interest proposed to be sold by the Selling Member upon the same
terms and conditions as stated in the aforesaid written offer to purchase by
giving written notice to the Selling Member of its intention to do so within
thirty (30) days after receipt by such other Member of written notice from the
Selling Member. The offer to sell shall be irrevocable during the thirty (30)
day period. If the non-selling Member fails to so notify the Selling Member of
its exercise of this right-of-first refusal within said period, the
right-of-first refusal as to such offer shall terminate and the Selling Member
shall be entitled to consummate the Transfer of its Economic Interest in the
Company to such third party purchaser on the terms set forth in the notice given
to the non-selling Member.

      In the event the non-selling Member gives written notice to the Selling
Member of its exercise of this right of first refusal to purchase all of the
Selling Member's Economic Interest in the Company, the non-selling Member shall
have the right to designate the time, date, and place of closing, provided that
the date of closing shall be within the later of sixty (60) days after the
written notice of acceptance by the non-selling Member or sixty (60) days of
receipt of any required regulatory approval for such transfer; provided,
however, that the non-selling Member shall be required to file for any such
regulatory approval within five (5) days of its written notice of acceptance. If
the non-selling Member fails to so file for any required regulatory approval
within such five (5) day period or fails to close within such sixty (60) day
period, the right-of-first refusal shall terminate and the Selling Member shall
be entitled to consummate the transfer of its Economic Interest in the Company
to such third party purchaser on the terms set forth in the notice given to the
non-selling Member.

      (b) The third party purchaser shall become a Permitted Transferee of the
Selling Member's Economic Interest in the Company and as a condition to
recognizing the effectiveness and binding nature of any such sale as against the
Company or otherwise, the non-transferring Member may require the Selling Member
and the Permitted Transferee to execute, acknowledge, and deliver to the Company
such instruments of transfer, assignment, and assumption and such other
certificates, representations, and documents, and to perform all such other
acts, which the non-transferring Member may reasonably deem necessary or
desirable to:

            (i) constitute such purchaser as a Permitted Transferee;

            (ii) confirm that the Permitted Transferee has accepted, assumed,
      and agreed to be subject to and bound by all of the terms, obligations,
      and conditions

<PAGE>   31

      of the Operating Agreement, as the same may have been further amended;

            (iii) preserve the status of the Company as a foreign or domestic
      limited liability company after the completion of such sale, under the
      laws of each jurisdiction in which the Company is qualified, organized, or
      does business;

            (iv) maintain the status of the Company as a partnership for federal
      tax purposes; and

            (v) assure compliance with any applicable state and federal laws,
      including, without limitation, securities laws and regulations.

      10.3  Transfers by Operation of Law.

      (a) In the event that a Member or Permitted Transferee (i) files a
voluntary petition under any bankruptcy or insolvency law, or a petition for the
appointment of a receiver, or makes an assignment for the benefit of creditors,
or (ii) is subjected involuntarily to such a petition or assignment, or to an
attachment or other legal or equitable interest with respect to its Membership
Interest, and such involuntary petition or assignment, or attachment or other
legal or equitable interest is not discharged within ninety (90) days after its
date, or (iii) is otherwise subject to a transfer of its Membership Interest by
operation of law or pursuant to judicial decree or settlement of judicial
proceedings, (any of the foregoing being a "Bankruptcy" and the Member or
Permitted Transferee being the "Bankrupt Person"), then in such event the
Bankrupt Person shall have only an Economic Interest in the Company, and shall
have no right to vote or participate in management of the Company or to
designate the President or Vice President, as the case may be, or members of the
Management Committee, and shall be deemed to have offered to sell all of its
Economic Interest to the other Member as provided in this Section 10.3. Such
offer of sale shall be irrevocable for a period of ninety (90) days from the
date on which the other Member first learned of the event which gave rise to the
Bankruptcy, and within said time period the other Member may, by delivering a
written notice of acceptance to the Bankrupt Person, accept the offer in respect
of all, but not less than all, of said Economic Interest. If the other Member
does not notify the Bankrupt Person of its decision to purchase the Economic
Interest within the applicable ninety (90) day offering period, said offer to
sell shall be deemed not to have been accepted by the other Member.

      (b) The purchase price at which the other Member may elect to purchase an
Economic Interest in accordance with the provisions of this Section 10.3 shall
be the Fair Market Value of the Bankrupt Person's Economic Interest.

      (c) If the other Member elects to purchase an Economic Interest in
accordance with the provisions of this Section 10.3, transfer of the Economic
Interest shall be made at the office of the Company on a mutually satisfactory
business day within the later of thirty (30) days of acceptance of the offer to
sell by the other Member or thirty (30) days of receipt

<PAGE>   32

of any required regulatory approvals for such transfer. Delivery of instruments
evidencing such transfer to the other Member, shall be made upon receipt by the
Bankrupt Person of cash representing the aggregate purchase price for the
Economic Interest or, at the option of the purchaser, of a promissory note for
the purchase price.

      10.4  Right of Redemption.

      (a) Following the earlier of (i) completion of the construction and
installation of the Backbone Network and the Ithaca and Binghamton Spurs, and
(ii) the second annual anniversary of the Effective Date, either Member may
elect for Energy East to withdraw from the Company upon the occurrence of a
Stalemate. Either Member may exercise this election by giving written notice to
the other Member, and effective as of the date of such notice (the "Withdrawal
Date") Energy East shall have only an Economic Interest in the Company and shall
have no right to participate in management of the Company or to designate the
Vice President or members of the Management Committee.

      (b) In the event that a Member elects for Energy East to withdraw from the
Company pursuant to this Section 10.4, the Company shall redeem the Membership
Interest of Energy East in accordance with one of the following procedures:

            (i) Energy East shall be distributed an IRU for dark fiber strands
in the Shared Network equal to the lesser of (1) such remaining dark fiber
strands in the Shared Network, or (2) one-half of such total fiber strands in
the Shared Network as of the Withdrawal Date. Energy East shall also be
distributed an IRU for dark fiber strands in any Segregated Network(s) for any
Division(s) in which it was the Participating Member. The IRU shall provide for
Energy East to pay the Company an access and management fee for operating and
maintaining the Fiber Optic Network

            (ii) If Energy East is a regulated telephone company as of the
Withdrawal Date, then following receipt of any necessary PSC approval received
within nine (9) months of the redemption of the Membership Interest of Energy
East and distribution of the IRU provided for in Section 10.4(b)(i), Energy East
shall be distributed from the Company:

                  (A) fifty percent (50%) of the customers utilizing the Shared
Network, Facilities, business and assets of the Company attributable to the
Economic Interest of Energy East as of the Withdrawal Date and including access
to the NYSEG Right-of-Way pursuant to the ROO Agreement, and

                  (B) all of the customers, Facilities, business and assets of
any Division(s) in which Energy East was the Participating Member.

Energy East shall not be distributed any customers, Facilities, business or
assets of any Division(s) in which Telergy was the Participating Member. The IRU
distributed pursuant to

<PAGE>   33

Section 10.4(b)(i) shall be terminated when the distributions are made pursuant
to Section 10.4(b)(ii). The petition to the PSC required by Section 10.4(b)(ii)
shall be made as soon as possible following the Withdrawal Date. The Company
shall retain the ROO Agreement.

      (c) Notwithstanding the foregoing or any other provision of this
Agreement, if Energy East has failed to make its Capital Contribution as and
when required by Section 8.1, Telergy may elect for Energy East to withdraw from
the Company; provided Telergy has given Energy East written notice of such
breach and ten (10) days within which to cure it. Effective on the tenth (10th)
day following such notice if Energy East has not cured its breach and made its
Capital Contribution required by Section 8.1, then the Company shall redeem the
Membership Interest of Energy East upon payment of one dollar ($1) and Energy
East shall withdraw from the Company. The Company shall retain the ROO
Agreement.

      10.5 Pledge. Telergy may pledge, hypothecate or mortgage its Economic
Interest to secure obligations or to guarantee indebtedness of the Company, or
of Telergy which is incurred for the benefit of the Company or a portion of
which is to be loaned to the Company pursuant to Section 8.3.

      10.6 Effecting a Transfer. The Transferring Member agrees, upon request of
the non-transferring Member, to execute such certificates or other documents and
perform such other acts as may be reasonably requested by the non-transferring
Member from time to time in connection with such Transfer or redemption of a
Membership Interest or Economic Interest. A Member who Transfers or purports to
Transfer a Membership Interest or Economic Interest in violation of this Article
X hereby indemnifies the Company and the remaining Member against any and all
loss, damage, or expense (including, without limitation, tax liabilities or loss
of tax benefits) arising directly or indirectly as a result of such Transfer or
purported Transfer.

      10.7 Admission of Substitute Member. The Permitted Transferee of an
Economic Interest may be admitted to the Company as a Substitute Member with the
unanimous approval of the Members. The Substitute Member shall agree in writing
to be bound by the terms of this Agreement and shall have all the rights and
obligations associated with a Membership Interest, including in particular the
right to vote and participate in the management and affairs of the Company as
permitted by this Agreement in accordance with the Voting Interest of the
Transferring Member, the Act and other applicable laws.

                                   ARTICLE XI

                   ADDITIONAL MEMBERS OR PERMITTED TRANSFEREES

      No new Member, Permitted Transferee or Substitute Member shall be entitled
to any retroactive allocation of losses, income, or expense deductions incurred
by the Company. The Manager may, at its option, close the Company books (as
though the Company's tax year had ended) or make pro rata allocations of loss,
income, and expense deductions to a new Member, Permitted Transferee or
Substitute Member for that portion of the Company's Fiscal Year in which it held

            (ii) discharge or make reasonable provision for all liabilities of
      the Company, including liabilities to Members who are also creditors and

                  (1) To each Member, with respect to the cumulative amount of

                        (A) to each Participating Member, that portion of its

<PAGE>   36

      (d) Notwithstanding anything to the contrary in this Agreement, upon a
liquidation, if any Member has a Deficit Capital Account (after giving effect to
all contributions, distributions, allocations, and other Capital Account
adjustments for all Fiscal Years, including the year during which such
liquidation occurs), such Member shall have no obligation to make any Capital
Contribution, and the negative balance of such Member's Capital Account shall
not be considered a debt owed by such Member to the Company or to any other
person for any purpose whatsoever.

      12.4 Return of Capital Contribution - Nonrecourse. Except as provided by
law or as expressly provided in this Agreement, upon dissolution, each Member
shall look solely to the assets of the Company for the return of its Capital

Capital Contribution of a Member, such Member shall have no recourse against any
other Member.

      12.5 Breach of Joint Venture and Operating Agreement; Remedies; Survival.
The parties agree and acknowledge that, in addition to any other remedies
specifically set forth herein, in the event of a breach of any provision of this

be entitled to receive from the breaching Member any and all damages suffered by
them as a result of such breach, together with all expenses incurred in
connection with the enforcement of this Operating Agreement and the collection
of such damages, including reasonable attorneys' fees. Without limitation of any
other means of recourse, in order to collect any amounts owing hereunder, the
Company and such non-breaching Members shall be entitled to set off against,
withhold, proceed against, or collect or receive directly from the Company, as
applicable, any amounts payable to the breaching Member pursuant to this
Operating Agreement. The obligations of the Members hereunder shall survive the
withdrawal of any Member and the dissolution or termination of the Company.

                                  ARTICLE XIII

                         REPRESENTATIONS AND WARRANTIES

      Each Member hereby represents and warrants to the other as follows:

prevent the acquisition of an interest in the Company or the other transactions
contemplated hereby; or (ii) call into question the validity, or materially

                                   ARTICLE XIV

                        DISPUTE RESOLUTION AND INJUNCTION

      Any matters which the Management Committee is unable to authorize by a
majority vote of its members (or such higher percentage as may be required by
this Operating Agreement), and any and all disputes arising out of, under, in
connection with, or relating to this Operating Agreement, the breach or any
alleged breach thereof, including disputes regarding the Economic Interests,
Voting Interests or Capital Accounts may be submitted to the Chief Executive
Officers of the Members who shall then attempt to resolve the dispute. Because
of the unique relationship of the Members in the Company and the unique value of
their interests therein, neither party shall be prevented from applying for and
obtaining injunctive relief in instances where, in the absence thereof, the
rights of such party cannot be otherwise adequately protected.

                                   ARTICLE XV

                                SEPARATE DIVISION

            Section 15.1 - New Projects. In the event a Member wants the Company
to construct a Spur and/or any additional path of the Fiber Optic Network, such
Member shall present the project to the Management Committee for its
consideration. If the Management Committee approves the project and authorizes
the construction and installation of fiber cable and Facilities, it shall also
approve a capital expenditures budget and the Capital Contributions necessary to
fund the capital costs of the project. If the Management Committee does not
approve the project, then the Member which presented the project to the
Management Committee (the "Participating Member") may cause the Company to
construct the Spur and/or the additional path of the Fiber Optic Network (a
"Segregated Network") through a separate Division of the Company to be operated
and accounted for independent of the regular business operations of the Company.

            Section 15.2 - Construction. The Company shall construct and install
the Segregated Network, including the fiber optic cable and Facilities, at the
direction of the Participating Member.

            Section 15.3 - Management and Allocations. The Division shall be
managed by the Manager and the Management Committee. Revenue and expense
associated with the operation of the Division shall be allocated between the
regular business operations of the Company and those of the Division in the
discretion of the Management Committee on a case-by-case basis, taking into
consideration all relevant factors, including, but not limited to, a customer's
use of the Segregated Network as well as other portions of the Fiber Optic
Network, direct maintenance costs of the Segregated Network, marketing and
related costs attributable to potential customers located along the Segregated
Network.

<PAGE>   39

            Section 15.4 - Special Provisions. Notwithstanding the provisions of
this Operating Agreement, the following special provisions shall apply with
respect to each Division:

            (i) The Participating Member will make Capital Contributions
      necessary to fund the capital costs of the Segregated Network as provided
      in Section 8.2(d), which will be accounted for as assets of the Division.

            (ii) The Participating Member's Capital Account and Membership
      Interest will reflect its sole ownership rights to the assets and revenue
      of the Division.

            (iii) The Participating Member will be specially allocated the
      revenue and expense associated with the operation of the Division, as
      determined by the Management Committee.

            (iv) If the Company leases dark fiber to third parties which
      involves the Segregated Network, the Participating Member will be
      specially allocated (1) all of the lease revenue, if the lease involves
      only the Segregated Network, or (2) a portion of the lease revenue based
      on the ratio of the number of miles being leased which are comprised of
      the Segregated Network to the total miles of the Fiber Optic Network which
      are being leased, but only if the lease involves portions of the Fiber
      Optic Network in addition to the Segregated Network.

            (v) If the Company liquidates and makes an in-kind distribution of
      its assets to its Members, the Participating Member would receive the
      assets of the Division(s), including the Segregated Network, for which it
      funded the capital costs. If the Company sells some or all of its assets,
      the portion of the sale proceeds allocable to the assets of a Division(s),
      including the Segregated Network, will be the sole property of the
      Participating Member which funded the capital costs of the Division, and
      will be distributed to the Participating Member. In the event of a merger
      of the Company with another Person, the portion of the consideration
      received in the transaction which is attributable to the assets of a
      Division(s), including the Segregated Network, will be paid to the
      Participating Member which funded the capital costs of the Division(s).
      The foregoing is not intended to be an exhaustive list, but rather is
      intended to be illustrative for how a Participating Member is to receive
      the benefits of a Division in which it has funded the capital costs.

                                   ARTICLE XVI

                           RELATIONSHIP OF THE PARTIES

      16.1 Recovery of Costs. The parties' agree to use their best efforts to
obtain

<PAGE>   40

long-term leases of dark fiber along the Backbone Network and the Ithaca and
Binghamton Spurs, which leases would cover substantially all of the engineering,
development, construction and any related regulatory costs (but not electronics
costs) associated with the Backbone Network and the Ithaca and Binghamton Spurs.
The parties intend to negotiate any such leases of dark fiber prior to
completion of construction of the Backbone Network and the Ithaca and Binghamton
Spurs. However, this provision does not limit the ability of the Company to
obtain the Capital Contributions or the loans from the Members as provided for
in this Operating Agreement.

      16.2 Revenue Sharing Procedures. The parties understand and agree that the
Company will interconnect the Fiber Optic Network to networks owned and operated
by local and long distance carriers including telephone companies that are
subsidiaries of Telergy. The parties recognize that such interconnection is
required under the Telecommunications Act of 1996 and by the Federal
Communications Commission and the PSC.

      16.3 Solicitation of Employees. Until the expiration of three (3) years
after either party ceases to be a Member of the Company, no party nor their
respective Affiliates will newly employ, engage or seek to employ or engage,
directly or indirectly, any employee of the Company or any employee of the
remaining Members of the Company who are providing services to the Company
without the written consent of the Company, unless such employee has been
discharged by the Company or by such Member or such employee is employed by an
entity that is acquired by a party or one of its Affiliates; provided, however,
that the foregoing provisions shall not apply to any employment or solicitation
of employment by a previous employer (or its Affiliates) of an employee of the
Company.

      16.4 Employee Hires. The parties will insure that the Company and its
subsidiaries will not employ, engage or seek to employ or engage, directly or
indirectly, any employee of a Member or its Affiliate, without the written
consent of such Member, unless such employee has been discharged by such Member
or its Affiliate or such employee is employed by an entity that is acquired,
directly or indirectly, by the Company.

      16.5 Construction Activity. The parties agree that the Company shall use
MasTec North America, Inc. or its subsidiaries as its prime contractor for all
construction activities of the Fiber Optic Network, Segregated Networks and
extensions thereto.

      16.6 Access to Right-of-Way. Subject to and in accordance with the
provisions of the ROO Agreement, the Company intends to construct underground,
buried and aerial fiber optic cables as the Fiber Optic Network, including such
laterals, spurs, loops and extensions in Rights-Of-Way that may be available to
NYSEG and its Affiliates. Such laterals, spurs, loops and extensions shall be
constructed and installed in accordance with the Business Plan as may be amended
from time to time. The parties recognize that the ROO Agreement may require
approval from the PSC and the parties agree to use their best efforts to obtain
such approval once NYSEG files the ROO Agreement with the PSC, which filing
Energy East shall cause to be made within ten (10) days after this Agreement

<PAGE>   41

is executed.

      16.7 Support Service Agreements. The parties currently contemplate that
certain services will be provided to the Company by employees of both of the
Members or by employees of companies which are subsidiaries of the Members. The
Members agree that Telergy shall provide services to the Company relating to
operating and maintaining a telecommunications business, excluding sales and
marketing services which will be performed by employees of the Company, and
Energy East shall provide services to the Company relating to the sale,
marketing and management of energy. The Manager shall be authorized to enter
into Support Services Agreements with Telergy and Energy East, and their
respective Affiliates, in substantially the same form as set forth in Exhibits B
and C, which establish the cost reimbursement procedures for the use by the
Company of the employees and other assets of the Members. The Manager will have
the responsibility to hire or contract for such other services as may be
appropriate and necessary for the proper functioning of the Company, subject to
the limitations on Manager's authority contained in Sections 5.1 and 5.2.

                                  ARTICLE XVII

indemnification shall be made to or on behalf of any Manager or member of the
Management Committee if a judgment or other final adjudication adverse to him

adjudicated, or that he personally gained in fact a financial profit or other
advantage to which he was not legally entitled; and, the Company shall pay
expenses incurred by or on behalf of such a person in defending such a civil or
criminal action or proceeding (including appeals) in advance of the final
disposition of such action or proceeding promptly upon receipt by the Company,

expenses so advanced to the extent that the person receiving the advancement is
ultimately found not to be entitled to indemnification for such expenses; and
the right to indemnification and advancement of defense expenses granted by or
pursuant to this Section 5.11 (i) shall not limit or exclude, but shall be in
addition to, any other rights which may be granted by or pursuant to any
statute, certificate of incorporation, by-law, resolution or agreement, (ii)

intent of this Section 5.11 to require the Company to indemnify the persons
referred to herein for the aforementioned judgments, fines, amounts paid in
settlement and expenses, including attorneys' fees, in each and every
circumstance in which such indemnification could lawfully be permitted by an
express provision, and the indemnification required by this Section 5.11 shall
not be limited by the absence of an express recital of such circumstances.

      (b) Insurance. The Company shall purchase and maintain insurance on behalf
of any person who is or was a Manager, or Management Committee member, and shall
have the power to purchase and maintain insurance on behalf of any person who is

of the Company as a member, principal, director, officer, trustee, partner,
fiduciary, employee, or agent of another Entity, pension, or other employee
benefit plan or other enterprise, against any liability asserted against that
person and incurred by that person in any such capacity, or arising out of that

indemnify that person against such liability under this Section 5.11.

Telcom will assign one or more customer service representatives familiar with
GPU Telcom's business activities to be employed by the Company at each of the
New Jersey and Pennsylvania offices. For a period of six (6) months from the
Effective Date, GPU Telcom shall make an employee available to the Company (at
the Company's expense) to handle financial, operational and other administrative
matters relating to the commencement of the Initial Business. GPU Telcom shall
not be required to make any Capital Contributions or otherwise fund the Business
of the Company, including but not limited to any requirement to fund the Company
IRU, the ongoing working capital requirements of the Company, the marketing of
telecommunications products and services on behalf of the Company on a resale
basis or as a facilities-based provider, or otherwise fund the Business of the
Company unless it agrees to do so in its capacity as a Member.

      8.2 Additional Capital Contributions. Each Member shall be obligated to
contribute the amount of capital as authorized by the unanimous vote or Consent
of the Members.

      (a) No Member shall be required to make any Capital Contribution in
addition to those contemplated by Section 8.1(a) or 8.2(b). In the event the
Members are required to make additional Capital Contributions as authorized by
the decision of the Members unanimous vote or Consent, the Members shall
participate in such additional Capital Contributions on a pro rata basis in
accordance with their Economic Interests. No additional Capital Contributions
may be made other than in cash without the approval of the Members. In the event
one Member makes additional Capital Contributions in accordance with this
Agreement and with the Consent of the other

                                       21
<PAGE>   22

Member, the non-contributing Member's Economic Interest shall be diluted as
agreed to by the Members.

      (b) Notwithstanding anything to the contrary contained in this Agreement,
including but not limited to Sections 8.1 and 8.2, in the event that the Manager
or the Management Committee reasonably determines that the Company's cash
reserves and reasonably anticipated revenues are less than is needed to satisfy
its existing liabilities or its budgeted needs for capital expenditures and
working capital during the succeeding twelve (12) months, the Manager, either
Member or the Management Committee shall be empowered to seek approval from the
Members (i) for additional Capital Contributions that are sufficient in the
reasonable judgment of the Manager or the Management Committee to fund the
anticipated shortfall, which approval may be withheld by either Member for any
or no reason, provided however that the failure by either GPU Telcom or TNS to
provide funds sought pursuant to this paragraph shall entitle either Member to
declare a Stalemate which shall be resolved in accordance with the provisions of
Section 7.10 and/or (ii) to obtain loans from third parties or any Member on
commercially reasonable terms.

      8.3 Other Contributions. TNS and GPU Telcom shall contribute their
expertise, name recognition, customer contacts and other intangible assets to
the Company to facilitate the Business of the Company. GPU Telcom hereby
authorizes the Company's use of the GPU Telcom name and reputation in marketing
to customers in the GPU Telcom Territory and to access GPU Telcom customers to
market telecommunications services; provided however, that GPU Telcom shall be
entitled to review and must approve any marketing materials (including written
materials or any prepared script used in oral presentations and subsequently
distributed in writing) that include the GPU Telcom name prior to the use of
such materials by the Company; and provided further that the Company shall not
make any use of the GPU Telcom name that would be reasonably likely to have a
material, detrimental or adverse impact on GPU or any of its Affiliate's
reputation or standing in the business community or their respective
relationship with any regulatory body. Upon receipt by the Company of adequate
revenues or other funding by the Members to pay for the Company IRU under the
Construction Operating Agreement, and upon such payment by the Company to GPU
Telcom for the Company IRU as provided in the Construction Operating Agreement,
GPU Telcom shall deliver the Company IRU and upon such delivery the Company then
shall commence providing facilities-based telecommunications products and
services in the GPU Telcom Territory and the Company or both Members (rather
than TNS alone) shall fund the marketing to customers of facilities-based
telecommunications services on a retail basis, which shall include compensating
TNS for performing certain billing and other services for the Company pursuant
to the Billing and Services Agreement. Neither party shall charge the Company or
be entitled to a credit to their respective Capital Accounts for the intangible
assets contributed hereunder.

      8.4 Capital Accounts.

      (a) A separate Capital Account shall be maintained for each Member in
accordance with the capital accounting rules of Section 704(b) of the Code. The
beginning balance in each Member's Capital Account shall be the amount of such
Member's initial Capital Contribution made pursuant to Section 8.1. Thereafter,
a Member's Capital Account shall be increased by (i) the amount of any
subsequent Capital Contribution to the Company by such Member; (ii) such
Member's allocable share of Net Profit and items in the nature of income or gain
which are allocated pursuant to Section 9.2; and (iii) such other amounts as may
be required for the Capital Account to be determined and maintained in
accordance with the rules of Section 1.704-1(b)(2)(iv) of the Treasury
Regulations (including Section 1.704-1(b)(2)(iv)(g) thereof). A Member's Capital
Account shall be decreased by (i) such Member's allocable share of Net Loss and
items in the nature of loss or deduction allocated pursuant to Section 9.2; (ii)
the amount of cash or the Fair Market Value of any property distributed from the
Company to such Member (reduced by the amount of debt, if any, assumed by such
Member in connection with the distribution); and (iii) such other amounts as may
be required for the Capital Account to be determined and maintained in
accordance with the rules of Section 1.704-1(b)(2)(iv) of the Treasury
Regulations (including Section 1.704-1(b)(2)(iv)(g) thereof). It is the parties'
specific intent that Capital Accounts shall be maintained in accordance with the
capital account maintenance rules contained in section 704(b) of the Code,
including the Treasury Regulations thereunder, and this Section 8.4(a) shall be
construed and applied to achieve such result.

      (b) Upon liquidation of the Company (or any Member's Membership Interest),
liquidating distributions will be made in accordance with the positive Capital
Account balances of the Members and in accordance with Section 12.3 after taking
into account all Capital Account adjustments for the Company's Fiscal Year
during which the liquidation occurs.

      8.5 Withdrawal or Reduction of Members' Contributions to Capital.

      (a) A Member shall not receive out of the Company's property any part of
its Capital Contribution until all liabilities of the Company have been paid.

      (b) A Member, irrespective of the nature of its Capital Contribution, has
only the right to receive cash in return for its Capital Contribution, except
for liquidation distributions under Section 12.

      (c) A Member may not withdraw from the Company or assign its Membership
Interest or Economic Interest prior to the dissolution and winding up of the
Company, except as provided in Article X.

                                   ARTICLE IX

                     ALLOCATIONS, INCOME TAX, DISTRIBUTIONS,
                             ELECTIONS, AND REPORTS

      9.1 Allocations of Profits and Losses from Operations. The Net Profits of
the Company for each Fiscal Year shall be allocated between the Members in
proportion to the Economic Interests held by Members. The Net Losses shall be
allocated between the Members in proportion to their Economic Interests;
provided, however, that if a Member's Capital Account is reduced to zero (0),
any additional Net Losses shall be allocated to the other Member until its
Capital Account is reduced to zero (0).

      9.2 Special Allocations to Capital Accounts and Certain Other Income Tax
Allocations. Notwithstanding Section 9.1 hereof:

      (a) In the event any Member unexpectedly receives any adjustments,
allocations, or distributions described in Sections 1.704-1(b)(2)(ii)(d)(4),
(5), or (6) of the Treasury Regulations, which create or increase a Deficit
Capital Account of such Member, then items of Company income and gain
(consisting of a pro rata portion of each item of Company income, including
gross income, and gain for such taxable year and, if necessary, for subsequent
years) shall be specially allocated to such Member in an amount and manner
sufficient to eliminate, to the extent required by the Treasury Regulations, the
Deficit Capital Account so created as quickly as possible. It is the parties'
intent that this Section 9.2(a) be interpreted to comply with the alternate test
for economic effect set forth in Section 1.704-1(b)(2)(ii)(d) of the Treasury
Regulations.

      (b) In the event any Member would have a Deficit Capital Account at the
end of any Company taxable year which is in excess of the sum of any amount that
such Member is obligated to restore to the Company under Section
1.704-1(b)(2)(ii)(c) of the Treasury Regulations and such Member's share of
minimum gain as defined in Section 1.704-2(g)(1) of the Treasury Regulations
(which is also treated as an obligation to restore in accordance with Section
1.704-1(b)(2)(ii)(d) of the Treasury Regulations), the Capital Account of such
Member shall be specially credited with items of Company income (including gross
income) and gain in the amount of such excess as quickly as possible.

      (c) Notwithstanding any other provision of this Section 9.2, if there is a
net decrease in the Company's minimum gain as defined in Treasury Regulation
Section 1.704-2(d) during a taxable year of the Company, then the Capital
Accounts of each Member shall be allocated items of income (including gross
income) and gain for such taxable year (and if necessary for subsequent years)
equal to that Member's share of the net decrease in Company minimum gain. This
Section 9.2(c) is intended to comply with the minimum gain charge-back
requirement of Section 1.704-2 of the Treasury Regulations and shall be
interpreted consistently therewith. If in any taxable year that the Company has
a net decrease in the Company's minimum gain, if the minimum gain charge-back
requirement would cause a distortion in the economic arrangement among the
Members and it is not expected that the Company will have sufficient other
income to correct that distortion, the Tax Matters Member may in its discretion
(and shall, if requested to do so by a Member) seek to have

                                       24
<PAGE>   25

the Internal Revenue Service waive the minimum gain charge-back requirement in
accordance with Treasury Regulation Section 1.704-2(f)(4).

      (d) Items of Company loss, deduction, and expenditures described in
Section 705(a)(2)(B) of the Code that are attributable to any non-recourse debt
of the Company and are characterized as partner (Member) non-recourse deductions
under Section 1.704-2(i) of the Treasury Regulations shall be allocated to the
Members' Capital Accounts in accordance with said Section 1.704-2(i) of the
Treasury Regulations.

      (e) Beginning in the first taxable year in which there are allocations of
"nonrecourse deductions" (as described in Section 1.704-2(b) of the Treasury
Regulations), such deductions shall be allocated to the Members in the same
manner as Net Profit or Net Loss is allocated for such period.

      (f) In accordance with Section 704(c)(1)(A) of the Code and Section
1.704(b)(2)(i)(iv) of the Treasury Regulations, if a Member contributes property
with a fair market value that differs from its adjusted basis at the time of
contribution, income, gain, loss, and deductions with respect to the property
shall, solely for federal income tax purposes (and not for Capital Account
purposes), be allocated among the Members so as to take account of any variation
between the adjusted basis of such property to the Company and its fair market
value at the time of contribution.

      (g) Any credit or charge to the Capital Accounts of the Members pursuant
to Sections 9.2 (a), (b), (c), (d), and/or (e) hereof shall be taken into
account in computing subsequent allocations of Net Profits and Net Losses
pursuant to Section 9.1, so that the net amount of any items charged or credited
to Capital Accounts pursuant to Sections 9.1 and 9.2 (a), (b), (c), (d), and/or
(e) shall to the extent possible, be equal to the net amount that would have
been allocated to the Capital Account of each Member pursuant to the provisions
of this Article IX if the special allocations required by Sections 9.2 (a), (b),
(c), (d), and/or (e) hereof had not occurred.

      9.3 Distributions. All distributions of Distributable Cash and property
shall be made to the Members in proportion to the percentages of their Economic
Interests on the record date of such distribution. Except as provided in Section
9.4 and except as restricted by a majority of the members of the Management
Committee as provided in Section 5.4(a)(v), all Distributable Cash shall be paid
to the Members periodically throughout the Fiscal Year during which it was
earned or otherwise received by the Company. The final payment of Distributable
Cash determined for each Fiscal Year shall be no later than March 30 following
the end of such Fiscal Year. The Management Committee shall use its best efforts
to authorize payments of Distributable Cash at such times as to enable each
Member to pay its federal and state income taxes determined at the highest
effective tax rate attributable to its share of the Company's taxable income.
Except as provided in Section 9.4, all distributions of property shall be made
at such time as determined by a majority of the members of the Management
Committee as provided in Section 5.4(a)(v).

      9.4 Limitation Upon Distributions. No distribution shall be declared and
paid if, in the determination of a majority of the members of the Management
Committee after giving effect to the distribution:

                                       25
<PAGE>   26

      (a) the Company would not able to pay its debts as they become due in the
usual course of business; or

      (b) all liabilities of the Company, other than liabilities for which the
recourse of creditors is limited to specified property of the Company, would
exceed the fair value of the Company's assets, except that the fair value of
property that is subject to a liability for which the recourse of creditors is
limited shall be included in the Company's assets only to the extent the fair
value of that property exceeds that liability.

            As contemplated by Section 508 of the Act, the members of the
Management Committee may base the determination under this Section on either:

      (a) financial statements prepared on the basis of accounting practices and
principles that are reasonable under the circumstances; or

      (b) a fair valuation or other method that is reasonable under the
circumstances.

            The members of the Management Committee shall make their
determination under this Section and authorize any distribution under Section
9.3 in accordance with the standards of Section 508 of the Act.

      9.5 Accounting Principles. The Net Profits and Net Losses of the Company
shall be determined as provided in Section 1.38 using the accrual method of
accounting applied on a consistent basis.

      9.6 Interest On Capital Contributions. No Member shall be entitled to
interest on its Capital Contribution, except as otherwise specifically provided
for in this Agreement.

      9.7 Accounting Period. The Company's accounting period shall be the Fiscal
Year.

      9.8 Books of Account and Records. At the expense of the Company, the
Manager shall maintain and preserve records and accounts of all operations and
expenditures of the Company for the length of time thereafter as may be required
to meet the records retention requirements of any taxing or regulatory body
having direct or indirect jurisdiction over all accounts, books, and other
relevant Company documents. The books of account shall accurately reflect all
transactions and other matters relating to the Company's business in such detail
and completeness as is customary and usual for businesses of the type engaged in
by the Company. As contemplated by Section 1102 of the Act, at a minimum the
Company shall keep at its principal place of business the following records and
shall be prepared to make such records available to regulatory agencies as may
be required by law:

      (a) a current list and a past list with the full names and last known
mailing addresses of each Member and each member of the Management Committee;

                                       26
<PAGE>   27

      (b) a copy of the Articles of Organization and all amendments thereto;

      (c) copies of the Company's federal, state, and local income tax returns

      (d) copies of the current and all prior Operating Agreements of the
Company, including all amendments thereto;

      (e) a writing setting forth the amount of cash and the Fair Market Value
of property or services contributed by each Member;

      (f) copies of any separate agreements pertaining to a Member's obligation
to contribute cash, property, or services; and

      (g) minutes of meetings of the Members, the Management Committee, or the
Manager and any written consents obtained from Members, the Management
Committee, or the Manager in lieu of a meeting; and

      (h) such other records as the Management Committee deems appropriate.

      Upon reasonable advance notice to the Manager, each Member shall have the
right, during ordinary business hours, to inspect and copy such Company
documents at the requesting Member's expense, subject to the Confidentiality
provision in Section 17.16; provided, however, that the Manager shall be
authorized, in its discretion, to withhold from or to restrict or condition the
access of one or more Members to information of the Company as and to the extent
contemplated by Section 1102 (c) of the Act.

      9.9 Returns and other Elections. The Manager shall cause the preparation
and timely filing of all tax returns required to be filed by the Company
pursuant to the Code and all other tax returns deemed necessary and required in
each jurisdiction in which the Company does business. Copies of such returns, or
pertinent information therefrom, shall be furnished to the Members within a
reasonable time after the end of the Company's Fiscal Year. All elections
permitted to be made by the Company under federal or state laws shall be made by
the Tax Matters Member, provided that the Tax Matters Member shall make any tax
election requested by the Management Committee or by a unanimous vote or Consent
of the Members.

      9.10 Statements and Reports.

      (a) As soon as practicable, but in no event later than ninety (90) days
after the end of each Fiscal Year, the Manager will cause to be prepared and
will have furnished to each of the Members, with respect to such period, (I) a
profit and loss statement, (ii) a statement of cash flows, (iii) a Company
balance sheet as of the close of such period, and (iv) such other statements
showing in reasonable detail each Member's interest in each of the items
described above. The foregoing statements will be prepared in accordance with
GAAP, consistently applied, and audited by an independent certified public
accounting firm of national reputation which shall be designated by the

                                       27
<PAGE>   28

unanimous vote or Consent of the Members in accordance with Section
5.4(a)(xiii), and the cost of preparing the statements and of each such audit
will be paid for by the Company.

      (b) Unaudited quarterly financial reports and updates with respect to the
Company's business shall be prepared and furnished to each Member as soon as
practicable after the end of each fiscal quarter, but in no event later than
forty-five (45) days following the end of the fiscal quarter.

      (c) Monthly financial reports and updates with respect to the Company's
business shall be prepared and furnished to each Member as soon as practicable

                                    ARTICLE X

                                 TRANSFERABILITY

      10.1 General. Except as otherwise specifically provided in this Article X,
without the unanimous vote or Consent of the Members, a Member shall not have
the right to sell, assign, transfer, exchange, or otherwise transfer
(collectively, "Transfer"), whether or not by operation of law, all or any part
of its Membership Interest.

      Notwithstanding the foregoing, a unanimous vote or Consent of the Members
shall not be required in order for a Member to Transfer all or any part of its
Membership Interest, and it shall be permissible for a Member to Transfer all or
part of its Membership Interest and this Agreement, to any direct or indirect
parent that wholly-owns the Member or to any wholly-owned direct or indirect
subsidiary thereof, or in connection with any merger or consolidation to which
the Member or its parent is the surviving and controlling party. Provided
further, in the event of a Transfer by a Member to any such parent or
wholly-owned direct or indirect subsidiary or a Transfer that may occur in
connection with any merger or consolidation where the Member or its parent is
the surviving and controlling party, the right of first refusal provisions of
Section 10.2 shall not apply.

      Each Member hereby acknowledges the reasonableness of the restrictions on
Transfer of Membership Interests imposed by this Operating Agreement in view of
the Company's purposes and the relationship of the Members. Accordingly, the
restrictions on Transfer contained in this Article X shall be specifically
enforceable.

      10.2 Right-of-First Offer.

      (a) A Member (the "Selling Member") that desires to sell its Economic
Interest in the Company to a qualified third party purchaser shall at least
thirty (30) days prior to effecting a Transfer, deliver a written notice to the
other Member stating the terms and conditions upon which the sale is to be made
and the consideration offered therefor. The other Member shall have the right to
purchase all (but not less than all) of the Membership Interest proposed to be
sold by the Selling Member upon the same terms and conditions as stated in the
aforesaid written notice of intention to sell by giving written notice to the
Selling Member of its intention to purchase the Selling Member's Membership
Interest within thirty (30) days after receipt by such other Member of written
notice from the Selling Member. The offer to sell shall be irrevocable during
the thirty (30) day period. If the non-selling Member fails to so notify the
Selling Member of its exercise of this right to purchase within said period, the
right to purchase as to such offer shall terminate and the Selling Member shall
be entitled to consummate the Transfer of its Membership Interest in the Company
to a third party purchaser on the terms set forth in the notice given to the
non-selling Member.

      In the event the non-selling Member gives written notice to the Selling
Member of its exercise of this right to purchase all of the Selling Member's
Membership Interest in the Company, the non-selling Member shall have the right
to designate the time, date, and place of closing, provided that the date of
closing shall be within the later of sixty (60) days after the written notice of
acceptance by the non-selling Member or sixty (60) days of receipt of any
required regulatory approval for such transfer; provided, however, that the
non-selling Member shall be required to file for any such regulatory approval
within five (5) days of its written notice of acceptance. If the non-selling
Member fails to so file for any required regulatory approval within such five
(5) day period or fails to close within such sixty (60) day period, the right to
purchase shall terminate and the Selling Member shall be entitled to consummate
the transfer of its Membership Interest in the Company to a third party
purchaser on the terms set forth in the notice given to the non-selling Member.

      (b) The third party purchaser shall become a Permitted Transferee of the
Selling Member's Membership Interest in the Company and as a condition to
recognizing the effectiveness and binding nature of any such sale as against the
Company or otherwise, the non-transferring Member may require the Selling Member
and the Permitted Transferee to execute, acknowledge, and deliver to the Company
such instruments of transfer, assignment, and assumption and such other
certificates, representations, and documents, and to perform all such other
acts, which the non-transferring Member may reasonably deem necessary or
desirable to:

            (i) constitute such purchaser as a Permitted Transferee;

            (ii) confirm that the Permitted Transferee has accepted, assumed,
and agreed to be subject to and bound by all of the terms, obligations, and
conditions of the Operating Agreement, as the same may have been further
amended;

            (iii) preserve the status of the Company as a foreign or domestic
limited liability

                                       29
<PAGE>   30

company after the completion of such sale, under the laws of each jurisdiction
in which the Company is qualified, organized, or does business;

            (iv) maintain the status of the Company as a partnership for federal
tax purposes; and

            (v) assure compliance with any applicable state and federal laws,
including, without limitation, securities laws and regulations.

      10.3 Transfers by Operation of Law.

      (a) In the event that a Member or Permitted Transferee (i) files a
voluntary petition under any bankruptcy or insolvency law, or a petition for the
appointment of a receiver, or makes an assignment for the benefit of creditors,
or (ii) is subjected involuntarily to such a petition or assignment, or to an
attachment or other legal or equitable interest with respect to its Membership
Interest, and such involuntary petition or assignment, or attachment or other
legal or equitable interest is not discharged within ninety (90) days after its
date, or (iii) is otherwise subject to a transfer of its Membership Interest by
operation of law or pursuant to judicial decree or settlement of judicial
proceedings, (any of the foregoing being a "Bankruptcy" and the Member or
Permitted Transferee being the "Bankrupt Person"), then in such event the
Bankrupt Person shall have only an Economic Interest in the Company, and shall
have no right to vote or participate in management of the Company or to
designate the Manager or members of the Management Committee, and shall be
deemed to have offered to sell all of its Economic Interest to the other Member
as provided in this Section 10.3. Such offer of sale shall be irrevocable for a
period of ninety (90) days from the date on which the other Member first learned
of the event which gave rise to the Bankruptcy, and within said time period the
other Member may, by delivering a written notice of acceptance to the Bankrupt
Person, accept the offer in respect of all, but not less than all, of said
Economic Interest. If the other Member does not notify the Bankrupt Person of
its decision to purchase the Economic Interest within the applicable ninety (90)
day offering period, said offer to sell shall be deemed not to have been
accepted by the other Member.

      (b) The purchase price at which the other Member may elect to purchase an
Economic Interest in accordance with the provisions of this Section 10.3 shall
be the Fair Market Value of the Bankrupt Person's Economic Interest.

      (c) If the other Member elects to purchase an Economic Interest in
accordance with the provisions of this Section 10.3, transfer of the Economic
Interest shall be made at the office of the Company on a mutually satisfactory
business day within the later of thirty (30) days of acceptance of the offer to
sell by the other Member or thirty (30) days of receipt of any required
regulatory approvals for such transfer. Delivery of instruments evidencing such
transfer to the other Member, shall be made upon receipt by the Bankrupt Person
of cash representing the aggregate purchase price for the Economic Interest , or
at the option of the purchaser, cash representing 20% of the aggregate purchase
price for the Economic Interest plus a three-year note for the balance of the
purchase price.

      10.4 Stalemate and Right of Redemption.

      (a) Upon the occurrence of a Stalemate, each Member shall use good faith
efforts to resolve the dispute giving rise to the Stalemate in accordance with
Section 7.10 or Section 7.17. If such Stalemate has not been resolved within ten
(10) days of its submission to the Members' principal executive officers (the
"Stalemate Date"), each of TNS and GPU Telcom shall then negotiate in good faith
to achieve a mutually agreeable purchase and sale arrangement at Fair Market
Value such that one Member would thereafter own all of the Membership Interests
in the Company. If the Stalemate Date has occurred on or after the two (2) year
anniversary of the Effective Date, and the Members are not able to negotiate a
purchase and sale arrangement within thirty (30) days after the Stalemate Date,
either Member may, for a period of ninety (90) days thereafter, subject to the
provisions of Section 10.2, seek to obtain a bona fide third party purchaser for
its Membership Interest and consummate a sale. If neither Member consummates a
sale, then each of TNS and GPU Telcom shall have the right, exercisable at any
time thereafter (provided that such Stalemate is continuing at the time of such
exercise) by delivery of written notice (the "Withdrawal Notice") to the other
Member, to elect for the Company to redeem GPU Telcom's Membership Interest in
the Company. The date of such notice shall hereinafter be referred to as the
"Withdrawal Date".

                                       31
