A. A Member may withdraw from membership upon compliance with such terms and conditions as the Board of Directors may
prescribe, provided, however, no Member shall be permitted to withdraw until its withdrawal has been approved by an affirmative vote of not less than two thirds (2/3) of all the Directors and it has met all its contractual
obligations, debts and liabilities to Old Dominion. Written notice of withdrawal shall be delivered to any officer of Old Dominion or to the Board of Directors at least ninety (90) days prior to the date upon which the withdrawal is proposed to

the Secretary of Old Dominion that such failure makes it liable to expulsion from membership and the failure shall have continued for at least ten (10) days after such notice was given. Within thirty (30) days after the Board shall have
recommended expulsion of a Member, a meeting of the Members shall be held at which such Member shall be given an opportunity to present its case, by counsel or otherwise, and the Board shall have the same opportunity, after which a vote shall be

Section 8.02 Patronage Capital

A. In connection with the furnishing of electric energy, Old Dominions operations shall be so conducted that all Members will,
through their patronage, furnish capital for Old Dominion. In order to induce patronage and to assure that Old Dominion will operate on a non-profit basis, Old Dominion is obligated to account on a patronage basis to all its Members for income
received and receivable from the furnishing of electric energy in excess of operating costs and expenses properly chargeable against the furnishing of electric energy, as herein provided. Amounts received from the furnishing of electric energy in
excess of operating costs and expenses at the moment of receipt by Old Dominion are received with the understanding that they are furnished by the patrons as capital. Other than as provided in subsection C of this Section 8.02, Old
Dominions income, operating costs and expenses shall be determined in accordance with accounting principles generally accepted in the United States of America.

Old Dominion is obligated to pay by credits to a capital account for each Member amounts in excess of operating costs and expenses in
accordance with Old Dominions Margin Stabilization Plan. The books and records of Old Dominion shall be set up and kept in such a manner that at the end of each fiscal year the amount of capital, if any, so furnished by each Member is clearly
reflected and credited in an appropriate record to the capital account of each Member, with each Members capital account reflecting the Members equity investment in Old Dominion. Old Dominion shall, within a reasonable time after the
close of the fiscal year, notify each Member of the amount of capital so credited to its account. All such amounts credited to the capital account of any Member shall have the same status as though they had been paid to the Member pursuant to a
legal obligation to do so and the Member had then furnished corresponding amounts for capital.

B. To the extent Old Dominion
elects to engage in the business of furnishing products and services other than electric service, amounts received and receivable therefrom in excess of operating costs and expenses properly chargeable against the furnishing of such products and
services shall be, insofar as permitted by law, allocated and assigned annually on a patronage basis and credited on the books of Old Dominion as patronage capital to those patrons so furnished such products and services, in substantially the same
manner provided in subsection A with respect to furnishing electric service.

C. In the event that Old Dominion shall not be
exempt from Federal income tax in any taxable year (pursuant to Section 501(c)(12) of the Internal Revenue Code), the provisions of this subsection C shall apply in lieu of the provisions of subsections A and B.



16



---

1. In any year governed by this subsection C, Old Dominions margins shall be computed
by determining the amount of Old Dominions taxable income for such year as computed for Federal income tax purposes (but determined without any deduction or exclusion for the margins allocated by Old Dominion to its Members). Additionally, in
any such year, Old Dominion shall determine the amount of its margins, as so computed, that is allocable to the furnishing of electric energy (electric margins) and allocable to business attributable to other than the furnishing of
electric energy (other margins), either of which may be in excess of Old Dominions margins for the taxable year. If Old Dominions electric margins or other margins shall be negative in any year, the amount of Old
Dominions electric margins or other margins, as the case may be, in subsequent taxable years (when positive) shall be reduced until the amount of such loss shall have been fully recouped against margins of the same character as the prior loss.
If, with respect to any year, Old Dominions taxable income (or the classification of such income as electric margins or other margins) shall be adjusted on audit, the amount of margins allocated by Old Dominion to its Members with respect to
such year in accordance with subsection C(2) will be retroactively increased or decreased to reflect the audit adjustment.



17



---

2. In connection with the furnishing of electric energy, Old Dominions operations
shall be so conducted that all Members will, through their patronage, furnish capital for Old Dominion. In order to induce patronage and to assure that Old Dominion will operate at cost on a cooperative non-profit basis, each year Old Dominion will
allocate to its Members any electric margins that it earns that year (if positive) based on the amounts of the Members respective patronage for the year with respect to the electric energy furnished by Old Dominion during that year. If Old
Dominion elects to engage in the business of furnishing products or services other than electric energy in any year, Old Dominion will allocate to its Members any other margins that it earns that year (if positive) based on the amounts of the
Members respective patronage for the year with respect to such products or services.

3. The books and records of Old
Dominion shall be set up and kept in such a manner that at the end of each fiscal year the amount of margins allocated to each Member in accordance with this subsection C is clearly reflected and credited in an appropriate record to the capital
account of each Member. Old Dominion shall, within a reasonable time after the close of the fiscal year, notify each Member of the amount of margins so credited to its capital account. Until such time as allocated margins are actually paid to the
Members of Old Dominion (as determined in the discretion of the Board of Directors of Old Dominion in accordance with Section 8.03 hereof), all margins credited to the capital account of any Member shall have the same status as though they had
been paid to the Member pursuant to a legal obligation to do so and the Member had then furnished corresponding amounts for capital.

Section 8.03 Retirement of Capital

In the event of dissolution or liquidation of Old Dominion, after all
outstanding indebtedness of Old Dominion shall have been paid, outstanding capital credits shall be retired without priority on a pro rata basis before any payments are made on account of property rights of Members.

If, at any time prior to dissolution or liquidation, the Board of Directors shall determine that the financial condition of Old Dominion
will not be impaired thereby, the capital then credited to Members accounts may be retired in full or in part. Termination of a Members membership shall not accelerate the payment of capital credits.

Section 8.04 Assignability of Capital

Capital credited to the account of each Member shall be assignable only on the books pursuant to written instructions from the assignor and only to successors in interest or successors in occupancy in all
or a part of such

Section 8.05 Classification of Business

In determining and allocating the operating costs and expenses to form the basis of determining, in turn, the respective amounts of capital
furnished by patrons through their patronage, it shall be the duty of the Board of Directors to classify the business done by Old Dominion with all of its patrons into appropriate classes or departments of business or patronage.

Operating margins will be allocated to each Member within each such classes or departments on a patronage basis after full allocation of all
direct and indirect costs associated with service. All patronage margins contributed by patrons within a given class of business shall be assigned to such patrons on a dollar volume basis of patronage, but no patronage capital shall be deemed to
have been contributed by, or shall be allocated to, any patron within any class of business, if the receipts from all patrons within such class do not exceed the costs and expenses chargeable or allocable to such class. The cost allocation
methodologies will be subject to periodic review by the Board of Directors.

Section 8.06 Contractual Character of Operations

The Members of Old Dominion, by dealing with Old Dominion, acknowledge that the terms of the Articles of Incorporation and

provisions.

indemnified by Old Dominion in defending a civil or criminal action, suit or proceeding in advance of the final disposition of such action, suit or proceeding upon receipt of an undertaking, by or on behalf of such person, to repay such amount if it
