     2.1    The WSPP experiment has been successfully concluded. Its main
            purpose was to determine the feasibility of a marketing arrangement
            which would increase the efficiency of interconnected power system
            operations above that already being accomplished with existing
            agreements through increased market knowledge and market pricing of
            commodities.

     2.2    The Parties now desire to proceed with a similar marketing
            arrangement on a long term basis for prescheduled and real-time
            coordinated power transactions, such as economy energy transactions,
            unit commitment service, firm system capacity/energy sales or
            exchanges. Accordingly, this Agreement, together with any applicable
            Confirmation Agreement, sets forth the terms and conditions to
            implement these services within any applicable rate ceilings set
            forth in the Service Schedules in conformance with FERC orders where
            applicable.

            accuracy of any statement or charge. The Party from which documents
            or data has been requested shall cooperate in providing the
            documents and data within a reasonable time period.

10.  UNCONTROLLABLE FORCES:

            No Party shall be considered to be in breach of this Agreement or
     any applicable Confirmation Agreement to the extent that a failure to
     perform its obligations under this Agreement or any such Confirmation
     Agreement shall be due to an Uncontrollable Force. The term "Uncontrollable
     Force" means an event or circumstance which prevents one Party from
     performing its obligations under one or more transactions, which event or
     circumstance is not within the reasonable control of, or the result of the
     negligence of the claiming Party, and which by the exercise of due
     diligence, the claiming Party is unable to avoid, cause to be avoided, or
     overcome. So long as the requirements of the preceding sentence are met,
     "Uncontrollable Forces" may include and are not restricted to flood,
     drought, earthquake, storm, fire, lightning, epidemic, war, riot, civil
     disturbance or disobedience, labor dispute, labor or material shortage,
     sabotage, restraint by court order or public authority, and action or
     nonaction by, or failure to obtain the necessary authorizations or
     approvals from, any governmental agency or authority.

     Party to settle any strike or labor dispute in which it may be involved.
     Any Party rendered unable to fulfill any of its obligations by reason of an
     Uncontrollable Force shall give prompt notice of such fact and shall
     exercise due diligence, as provided above, to remove such inability within
     a reasonable time period. If oral notice is provided, it shall be promptly
     followed by written notice.

          Notwithstanding the "due diligence" obligations or obligations to
     remove or remedy the causes set forth in the foregoing paragraph (which do
     not apply to this paragraph except as specified below), where the entity
     providing transmission services for transactions under any Service Schedule
     interrupts such transmission service, the interruption in transmission
     service shall be considered an Uncontrollable Force under this Section 10
     only in the following two sets of circumstances:

     (1)  An interruption in transmission service shall be considered an
          Uncontrollable Force if (a) the Parties agreed on a transmission path
          for that transaction at the time the transaction under this Agreement
          was entered into by the Parties' thereto, (b) firm transmission
          involving that transmission path was obtained pursuant to a
          transmission tariff or contract to effectuate the transaction under
          the applicable Service Schedule, and (c) the entity providing
          transmission service curtailed or interrupted such firm transmission
          pursuant to the applicable transmission tariff or contract;

     (2)  if the Parties did not agree on the transmission path for a
          transaction at the time the transaction was entered into, an
          interruption in transmission service shall be

          considered an Uncontrollable Force only if (a) the Party contracting
          for transmission services shall have made arrangements with the entity
          providing transmission service for firm transmission to effectuate the
          transaction under the applicable Service Schedule, (b) the entity
          providing transmission service curtailed or interrupted such
          transmission service due to an event of Uncontrollable Forces or
          provision of like effect, and (c) the Party which contracted for such
          firm transmission services could not obtain alternate energy at the
          delivery point, alternate transmission services, or alternate means of
          delivering energy after exercising due diligence.

          No Party shall be relieved by operation of this Section 10 of any
     liability to pay for power delivered to the Purchaser or to make payments
     then due or which the Party is obligated to make with respect to
     performance which occurred prior to the Uncontrollable Force.

11.  WAIVERS:

          Any waiver at any time by any Party of its rights with respect to a
     default under this Agreement or any Confirmation Agreements, or any other
     matter under this Agreement, shall not be deemed a waiver with respect to
     any subsequent default of the same or any other matter.

            Nothing contained in this Agreement shall give FERC jurisdiction
            over those Parties not otherwise subject to such jurisdiction or be
            construed as a grant of jurisdiction over any Party by any state or

            If, upon filing of this Agreement by Parties subject to FERC
            jurisdiction under the Federal Power Act, FERC orders a hearing to
            determine whether this Agreement or a Service Schedule under this
            Agreement is just and reasonable under the Federal Power Act, the

            Service Schedule to be just and reasonable without changes or new
            conditions unacceptable to the Parties, is no longer subject to
            judicial review. Any changes or conditions imposed by any agency or
            court, including FERC ordering a hearing, shall be cause for
            immediate withdrawal by any nonconsenting Party.

     except to a Successor in Operation of such Party. With regard to the
     transfer of the rights and obligations of any Party associated with
     transactions under the Service Schedules, neither Party may assign such
     rights or obligations unless (a) the other Party provides its prior written
     consent which shall not be unreasonably withheld; or (b) the assignment is
     to a Successor in Operation which provides reasonable creditworthiness
     assurances (see Section 27 for examples of such assurances) if required by
     the non-assigning Party based upon its reasonably exercised discretion. Any
     successor or assignee of the rights of any Party, whether by voluntary
     transfer, judicial or foreclosure sale or otherwise, shall be subject to
     all the provisions and conditions of this Agreement and Confirmation
     Agreements (where applicable) to the same extent as though such successor
     or assignee were the original Party under this Agreement or the

            in order to remain a Party to this Agreement

     16.3   Being a Party to this Agreement shall not serve as a substitute for

            operates a Control Area and any other Party which operates within
            that Control Area.

     16.4   Any entity that becomes a Party to this Agreement which was not a

            prior efforts and costs incurred by the parties to the experimental
            Western Systems Power Pool Agreement, which efforts greatly

            credited to future costs of the WSPP incurred hereunder.

     16.5   In addition to requirements set forth elsewhere in this Agreement
            imposed on Parties as part of their membership in the WSPP, each

                   provided that the foregoing prohibition shall not apply in

                   Notwithstanding any other provision in this Agreement, a
                   Party that seeks to conduct discovery or take testimony in
                   breach of this provision shall compensate the WSPP and its
                   officers, attorneys, and consultants, as applicable, for all

                      hour is less than the applicable hourly Contract Quantity,
                      then the Purchaser shall be liable for (a) the product of
                      the amount (whether positive or negative), if any, by
                      which the Contract Price differed from the Sales Price
                      (Contract Price - Sales Price) and the amount by which the
                      quantity received by the Purchaser was less than the
                      hourly Contract Quantity; plus (b) the amount of

            (b)  The Parties agree that the amounts recoverable under this
                 Section 21.3 are a reasonable estimate of loss and not a
                 penalty, and represent the sole and exclusive remedy for the
                 Performing Party. Such amounts are payable for the loss of
                 bargain and the loss of protection against future risks.

            (c)  Each Party agrees that it has a duty to mitigate damages in a
                 commercially reasonable manner to minimize any damages it may
                 incur as a result of the other Party's performance or

                 of the damages under this Section 21.3, the Non-Performing
                 Party shall pay the full amount of the damages as required by
                 Section 9 of this Agreement to the Performing Party. After
                 informal dispute resolution as required by Section 34.1, any
                 remaining dispute involving the calculation of the damages
                 shall be referred to binding dispute resolution as provided by
                 Section 34.2 of this Agreement. If resolution or agreement
                 results in refunds or the need for refunds to the

                       reject, in whole or in part, or challenge the validity
                       of, any guarantee.

     22.2   REMEDIES FOR EVENTS OF DEFAULT

                 If an Event of Default occurs, the Non-Defaulting Party shall
            possess the right to terminate all transactions between the Parties
            under this Agreement upon written notice (by facsimile or other
            reasonable means) to the Defaulting Party, such notice of
            termination to be effective immediately upon receipt. If the
            Non-Defaulting Party fails to exercise this right of termination
            within thirty (30) days following the time when the Event of Default
            becomes known (or more than thirty days if the Non-Defaulting and
            Defaulting Parties agree to an extension), then such right of
            termination shall no longer be available to the Non-Defaulting Party
            as a remedy for the Event(s) of Default; provided, however, this
            thirty day requirement for exercising termination rights shall not
            apply to defaults pursuant to Sections 22.1(c) and 22.1(e)(iii). The
            Non-Defaulting Party terminating transaction(s) under this Section
            22.2 may do so without making a filing at FERC.

                 Upon termination, the Non-Defaulting Party shall liquidate all
            transactions as soon as practicable, provided that in no event will
            the Non-Defaulting Party be allowed to liquidate Service Schedule A
            transactions. The payment associated with termination ("Termination
            Payment") shall be calculated in accordance with

            of such notice of termination by the Defaulting Party, the
            Non-Defaulting Party may exercise any remedies available to it under
            Section 21.3 of this Agreement or Confirmation Agreement(s), and any
            other remedies available to it at law or otherwise.

                 Upon termination, the Non-Defaulting Party may withhold any
            payments it owes the Defaulting Party for any obligations incurred
            prior to termination under this Agreement or Confirmation
            Agreement(s) until the Defaulting Party pays the Termination Payment
            to the Non-Defaulting Party. The Non-Defaulting Party shall possess
            the right to set-off the amount due it under this Section 22 by any
            such payments due the Defaulting Party as provided in Section
            22.3(d).

     22.3   LIQUIDATION CALCULATION OPTIONS

                 The Non-Defaulting Party shall calculate the Termination
            Payment as follows:

            (a)  The Gains and Losses shall be determined by comparing the value
                 of the remaining term, transaction quantities, and transaction
                 prices under each Terminated Transaction had it not been
                 terminated to the equivalent quantities and relevant market
                 prices for the remaining term either quoted by a bona fide
                 third-party offer or which are reasonably expected to be
                 available in the market under a replacement contract for each
                 Terminated Transaction. To ascertain the market prices of a
                 replacement contract, the Non-Defaulting Party may consider,
                 among other valuations, quotations

                 length of the remaining term and differences in transmission.
                 It is expressly agreed that the Non-Defaulting Party shall not
                 be required to enter into replacement transactions in order to
                 determine the Termination Payment.

            (b)  The Gains and Losses calculated under paragraph (a) shall be
                 discounted to present value using the Present Value Rate as of
                 the time of termination (to take account to the period between

                 amount would have otherwise been due pursuant to the relevant

                 0.50% plus the yield reported on page "USD" of the Bloomberg

                 Losses and Costs exceed its aggregate Gains, the Defaulting
                 Party shall, within three (3) Business Days of receipt of such

                 rate from the time notice of termination was received until
                 paid. If the Non-Defaulting Party's aggregate Gains exceed its

                 set-off as provided in paragraph (d), shall pay the remaining

                 termination was received until the Defaulting Party receives
                 payment.

            (d)  The Non-Defaulting Party shall aggregate or set off, as
                 appropriate, at its election, any or all other amounts owing
                 between the Parties (discounted at the Present Value Rate)

                 the Termination Payment so that all such amounts are aggregated
                 and/or netted to a single liquidated amount. The net amount due

                       the contract(s) being terminated. The Non-Defaulting

                       to the Defaulting Party within three Business Days of the

                       contract(s). That method shall ensure that the Defaulting

                       the term of each contract which allows it to receive the

                       owing money defaults to require that Party to pay all
                       monies owed under all of the contracts subject to this
                       Section 22.3(e) within three Business Days of receipt of
                       the written notice. The monies to be paid under this

     22A.   DEFAULT IN PAYMENT OF WSPP OPERATING COSTS:

            22A.1  A Party shall be deemed to be in default in payment of its

                   Agreement, if any, when payment is not received within ten
                   (10) days after receipt of written notice. A default by any
                   Party in such payment obligations shall be cured by payment
                   of all overdue amounts together with interest accrued at the
                   rate of one percent (1%) per month, or the maximum interest
                   rate permitted by law, if any, whichever is less, prorated by
                   days from the due date to the date the payment curing the
                   default is made unless and until the Executive Committee
                   shall determine another rate.

            22A.2  A defaulting Party, which is in default under Section 22.A1,

                   shall not be revoked, however, unless said Party has received
                   at least thirty (30) days written notice of the
                   non-defaulting Parties' intent to revoke such rights. Said
                   notice shall state the date on which the revocation of rights
                   shall become effective if the default is not cured and shall
                   state all actions which must be taken or amounts which must
                   be paid to cure the default. This provision allowing the
                   non-defaulting Parties to revoke such rights is in addition
                   to any other remedies provided in this Agreement or at law
                   and shall in no way limit the non-defaulting Parties' ability
                   to seek judicial enforcement of the defaulting Party's
                   obligations to pay its share of the operating costs under
                   this Agreement. Upon the effective date of such revocation of
                   rights, the defaulting party shall not be allowed to enter
                   into any new transactions under this Agreement. The
                   defaulting party under the Agreement or any Confirmation
                   Agreements shall be required to carry out all obligations
                   that existed prior to the effective date of such revocation.
                   If a defaulting Party's rights under this Agreement have been
                   revoked, the Executive Committee may restore that Party's
                   rights upon the defaulting Party paying all amounts due and
                   owing under this Agreement.

27.  CREDITWORTHINESS:

          Should a Party's creditworthiness, financial responsibility, or
     performance viability become unsatisfactory to the other Party in such
     other Party's reasonably exercised discretion with regard to any
     transaction pursuant to this Agreement or any Confirmation Agreement, the
     dissatisfied Party (the "First Party") may require the other Party (the
     "Second Party") to provide, at the Second Party's option (but subject to
     the First Party's acceptance based upon reasonably exercised discretion),
     either (1) the posting of a Letter of Credit, (2) a cash prepayment, (3)
     the posting of other acceptable collateral or security by the Second Party,
     (4) a Guarantee Agreement executed by a creditworthy entity; or (5) some
     other mutually agreeable method of satisfying the First Party. The Second
     Party's obligations under this Section 27 shall be limited to a reasonable
     estimate of the damages to the First Party

     (consistent with Section 22.3 of this Agreement) if the Second Party were
     to fail to perform its obligations. Events which may trigger the First
     Party questioning the Second Party's creditworthiness, financial
     responsibility, or performance viability include, but are not limited to,
     the following:

     (1)  The First Party has knowledge that the Second Party (or its Guarantor
          if applicable) are failing to perform or defaulting under other
          contracts.

     (2)  The Second Party has exceeded any credit or trading limit set out in
          the Confirmation Agreement or other agreement between the Parties.

     (3)  The Second Party or its Guarantor has debt which is rated as
          investment grade and that debt falls below the investment grade rating
          by at least one rating agency or is below investment grade and the
          rating of that debt is downgraded further by at least one rating
          agency.

     (4)  Other material adverse changes in the Second Party's financial
          condition occur.

     (5)  Substantial changes in market prices which materially and adversely
          impact the Second Party's ability to perform under this Agreement or
          any Confirmation Agreement occur.

          If the Second Party fails to provide such reasonably satisfactory
     assurances of its ability to perform a transaction hereunder within three
     (3) Business Days of demand therefore, that will be considered an Event of
     Default under Section 22 of this Agreement and the First Party shall have
     the right to exercise any of the remedies provided for under

     that Section 22. Nothing contained in this Section 27 shall affect any
     credit agreement or arrangement, if any, between the Parties.

28.  NETTING:

     28.1   If the Purchaser and the Seller are each required to pay an amount
            to each other in the same calendar month for transactions under this
            Agreement, then such amounts with respect to each Party may be
            aggregated and the Parties may discharge their obligations to pay
            through netting of the respective amounts due, in which case the
            Party, if any, owing the greater aggregate amount may pay to the
            other Party the difference between the amounts owed. Each Party
            reserves to itself all rights, set-offs, counterclaims, and other
            remedies and defenses (to the extent not expressly herein waived or
            denied) which such Party has or may be entitled to arising from or
            out of this Agreement and any applicable Confirmation Agreements.

     28.2   Parties shall net payments (associated with transactions under this
            Agreement and Confirmation Agreement) in accordance with Exhibit A,
            if such Parties have executed the form attached as Exhibit A. The
            Parties obligation to net shall include the netting of all payments
            received by the Parties in the same calendar month. Parties that
            have executed Exhibit A shall provide a signed copy of

            Exhibit A to a representative of the WSPP and to any Party that
            requests a copy and indicate on the WSPP Homepage that they have so
            executed Exhibit A (once the WSPP Homepage possesses the necessary
            capability). If a Party indicated its election to net payments on
            the WSPP Homepage and that Party desires to withdraw its agreement
            to net, that Party shall provide at least 30 days notice on the WSPP
            Homepage of the change in its election to net and also shall
            provide, concurrent with its withdrawal notice, written notice to
            all Parties with which it has ongoing transactions or with which it
            has committed to future transactions under the Agreement at the time
            of the notice. Any such changes in netting status shall apply
            beginning at least 30 days after notice required by this Section
            28.2 is provided and only shall apply to transactions agreed to
            beginning on or after the date the change in netting status becomes
            effective.

     28.3   The Parties may by separate agreement either through a Confirmation
            Agreement or some other agreement set out specific terms relating to
            the implementation of the netting in addition to or in lieu of
            Exhibit A.

     defend, and hold harmless the Purchaser from any claims for such taxes. The
     Contract Price does not include reimbursement for, and the Purchaser is
     liable for and shall pay, cause to be paid, or reimburse the Seller for if
     the Seller has paid, all taxes applicable to a transaction arising at and
     from the delivery point, including any taxes imposed or collected by a
     taxing authority with jurisdiction over the Purchaser. The Purchaser shall
     indemnify, defend, and hold harmless the Seller from any claims for such
     taxes. Either Party, upon written request of the other Party, shall provide
     a certificate of exemption or other reasonably satisfactory evidence of
     exemption if either Party is exempt from taxes, and shall use reasonable
     efforts to obtain and cooperate with the other Party in obtaining any
     exemption from or reduction of any tax. Taxes are any amounts imposed by a
     taxing authority associated with the transaction.

30.  CONFIDENTIALITY:

     30.1   The terms of any transaction under this Agreement or any other
            information exchanged by the Purchaser and Seller relating to the
            transaction shall not be disclosed to any person not employed or
            retained by the Purchaser or the Seller or their affiliates, except
            to the extent disclosure is (1) required by law, (2) reasonably
            deemed by the disclosing Party to be required to be disclosed in
            connection with a dispute between or among the Parties, or the
            defense of any litigation or dispute, (3) otherwise permitted by
            consent of the other Party, which consent shall not be unreasonably

            to a developer of an index of electric power prices in accordance
            with Section 30.2. In the event disclosure is made pursuant to this
            provision, the Parties shall use reasonable efforts to minimize the
            scope of any disclosure and have the recipients maintain the
            confidentiality of any documents or confidential information covered
            by this provision, including, if appropriate, seeking a protective
            order or similar mechanism in connection with any disclosure. This

            hereafter in the public domain (except as a result of a breach of
            this provision).

     30.2   A Party may disclose the terms of transactions under this Agreement,
            excluding the identities of parties, to any developer of any index
            of electric power prices without violation of the confidentiality
            obligations under Section 30.1 if: (1) the disclosing Party and the
            index developer have entered into a written agreement, prior to the
            disclosure, under which the developer has agreed to use the
            information solely for the development of an index of electric power
            prices for publication and not for any other purpose; and (2) the
            index with respect to which disclosure is made is an aggregation of
            terms of transactions and does not identify terms of single
            transactions or the identities of parties to transactions.

31.  TRANSMISSION TARIFF:

          Pursuant to FERC Order No. 888, issued on April 24, 1996, and FERC
     orders where applicable, the WSPP Default Transmission Tariff has been
     filed and has become effective. The Parties agree to be bound by the terms

32.  TRANSACTION SPECIFIC TERMS AND ORAL AGREEMENTS:

            following methods: (1) provision of pertinent information through

            oral conversation, provided that such oral conversation is recorded
            electronically. By mutual agreement and consistent with and pursuant
            to the provisions of this Section 32, the Parties to a transaction

            this Agreement may agree to modify any term of this Agreement which
            applies to such transaction (but not to provisions regarding the
            operation of the WSPP as an organization including Sections 7 and
            8), such agreement to be reflected in a Confirmation Agreement.
            Written confirmation shall be required for all transactions of one
            week or more. Upon request of the Purchaser or at the election of
            the Seller, the Seller shall provide written confirmation which must
            be received by the Purchaser within five Business Days of the date
            of the agreement or request. The Purchaser shall have five Business
            Days from date of receipt to respond to the confirmation. If the
            Purchaser does not respond within that time period, the Seller's
            written confirmation shall be considered as accepted and final
            except as provided in Section 32.5. If the Seller fails to provide
            any required written confirmation within five Business Days, as
            described above, then the Purchaser may submit a written
            confirmation to the Seller. The Purchaser shall submit such written
            confirmation within five Business Days after the deadline for
            submitting a written confirmation applicable to the Seller as set
            forth above has expired. If the Seller fails to respond to
            Purchaser's confirmation within five Business Days, then the
            Purchaser's written confirmation shall be considered as accepted and
            final except as provided in Section 32.5. Notwithstanding the
            foregoing, any failure of the Seller or the Purchaser to provide
            written confirmation of the transaction shall not invalidate any
            oral agreement of the Parties except for oral agreements prohibited
            by Section 32.5. Nor shall any oral agreement of the Parties be
            considered invalidated

     32.2   The Parties agree not to contest, or assert any defense with respect
            to, the validity or enforceability of any agreement to the terms
            concerning a specific transaction(s), on the basis that
            documentation of such terms fails to comply with the requirements of
            any statute that agreements be written or signed. Each Party
            consents to the recording by the other Party, without any further
            notice, of telephone conversations between representatives of the
            Parties, which contain agreements to or discussion concerning the
            terms of a specific transaction(s). All such recordings may be
            introduced and admitted into evidence for the purpose of proving
            agreements to terms, and any objection to such introduction or
            admission for such purpose is hereby expressly waived. The terms
            documented hereunder, whether stated in a written document or a
            recording, are intended by the Parties as a final expression of
            their agreement with respect to such terms as are included therein
            and may not be contradicted by evidence of any prior agreement, but
            may be supplemented by course of dealing, performance, usage of

            In the event of a conflict between a binding and effective
            Confirmation Agreement and this Agreement, the Confirmation
            Agreement shall govern.

     32.4   The Seller shall not be required to file written confirmations with

            paragraphs (a) - (l) of Exhibit C, those Non-Standard Confirmation
            Provisions shall not be deemed to be accepted pursuant to Section
            32.1 unless agreed to: (i) orally, with that oral agreement recorded
            (provided that such oral agreement option only shall be available

            a particular transaction under this Agreement. Unless the Parties
            expressly state and agree that all the terms and conditions of such

            mediator from a list of ten (10) candidates provided by the Chairman
            of the WSPP Operating Committee or his or her designee. If the

            or indirect interest in either Party or the subject matter of the
            mediation. The WSPP shall establish procedures for the appointment
            of mediators and the conduct of mediation and those procedures shall
            apply to the mediation.

     34.2   BINDING DISPUTE RESOLUTION

                 The Parties to a dispute may elect binding dispute resolution
            using the following process unless binding arbitration of certain
            disputes is required under this Agreement in which event the Parties
            shall use the process set forth in this Section 34.2 to resolve such
            disputes, unless the Parties otherwise agree:

            (a)  WSPP Dispute Resolution: A Party to a dispute (if binding
                 dispute resolution is required) or all Parties to a dispute (if
                 agreement of the Parties is required for binding dispute
                 resolution) may initiate binding dispute resolution under WSPP
                 procedures by notifying the Chairman of the WSPP Operating
                 Committee or his or her designee. The Chairman or his or her
                 designee shall provide the Parties with a list of ten (10)
                 eligible arbitrators. Within ten (10) days of receiving the
                 list, the Parties shall agree on a single arbitrator from the
                 list to conduct the arbitration, or notify the Chairman of the
                 Operating Committee or the designee of their inability to reach
                 agreement. If notified of the Parties inability to reach
                 agreement, then the Chairman or the designee shall choose the
                 arbitrator from the list within five (5) days. Neither the

                 arbitrators for the Parties to choose from or in selecting the
                 arbitrator (if the Parties are unable to do so) shall possess a
                 direct or indirect interest in either Party or the subject
                 matter of the arbitration. The Procedures to be used for this
                 arbitration shall follow the arbitration procedures which shall
                 be developed and maintained by the WSPP and the procedures will
                 be generally consistent with the commercial arbitration rules
                 of the American Arbitration Association though not involving
                 the Association.

                 If the Parties agree to binding dispute resolution under this
            Section 34.2, each Party understands that it will not be able to
            bring a lawsuit concerning any dispute that may arise which is
            covered by this arbitration provision. Notwithstanding the
            foregoing, nothing herein is intended to waive any provision of the
            Federal Arbitration Act, 9 U.S.C. Section 1, et. seq., or any right
            under state statute or common law to challenge an arbitration award
            or to prevent any action to enforce any arbitration award.

                 A Party's liability and damages under any arbitration award
            resulting from the process set forth in this Section 34.2 shall be
            limited as provided in this Agreement or in any Confirmation
            Agreement.

     34.3   COSTS

                 Each Party shall be responsible for its own costs and those of
            its counsel and representatives. The Parties shall equally divide
            the costs of the arbitrator or mediator and the hearing.

     34.4   CONFIDENTIALITY

                 Any arbitration or mediation under this Section 34 shall be
            conducted on a confidential basis and not disclosed, including any
            documents or results which shall be considered confidential, unless
            the Parties otherwise agree or such disclosure is required by law.

35.  FORWARD CONTRACTS:

          The Parties acknowledge and agree that all transactions under the
     Agreement and Confirmation Agreement(s) are forward contracts and that the
     Parties are forward contract merchants, as those terms are used in the
     United States Bankruptcy Code. The Parties acknowledge and agree that all
     of their transactions, together with this Agreement and the related
     Confirmation Agreement(s) form a single, integrated agreement, and
     agreements and transactions are entered into in reliance on the fact that
     the agreements and each transaction form a single agreement between the
     Parties.

36.  TRADE OPTION EXCEPTION

          The Parties intend that any Physically Settled Option under this
     Agreement shall qualify under the trade option exception, 17 C.F.R. Section
     32.4. Accordingly, each Party buying or selling a Physically Settled Option
     agrees and warrants that any such option

37.  ADDITIONAL REPRESENTATIONS AND WARRANTIES:

          Each Party warrants and represents to the other(s) that it possesses
     the necessary corporate, governmental and legal authority, right and power

     transaction or transactions and to perform each and every duty imposed, and
     that the Parties' agreement to buy and sell power under this Agreement and
     the Confirmation Agreement represents a contract. Each Party also warrants
     and represents to the other(s) that each of its representatives executing
     or agreeing through a Confirmation Agreement to a transaction under this
     Agreement is authorized to act on its behalf.

          Each Party further warrants and represents that entering into and
     performing this Agreement and any applicable Confirmation Agreement does
     not violate or conflict with its Charter, By-laws or comparable constituent
     document, any law applicable to it, any order or judgment of any court or
     other agency of government applicable to it or any agreement to which it is
     a party and that this Agreement and applicable Confirmation Agreement(s),
     constitute a legal, valid and binding obligation enforceable against such
     Party in accordance with the terms of such agreements.

          Each Party also represents that it is solvent and that on each
     delivery this representation shall be deemed renewed unless notice to the
     contrary is given in writing by the Purchaser to the Seller before
     delivery.

38.  FLOATING PRICES:

     38.1   In the event the Parties intend that the price for a transaction is
            to be based on an index, exchange or any other kind of variable
            reference price (such price being a "Floating Price"), the Parties
            shall specify the "Floating Price" to be used to calculate the
            amounts in a Confirmation Agreement due Seller for that transaction.

     38.2   Market Disruption. If a Market Disruption Event has occurred and is
            continuing during the Determination Period, the Floating Price for
            the affected Trading Day shall be determined as follows. The Parties
            shall negotiate in good faith to agree on a Floating Price (or a
            method for determining a Floating Price) for the affected Trading
            Day. If the Parties have not so agreed on or before the twelfth
            Business Day following the first Trading Day on which the Market
            Disruption Event occurred or existed, then the Floating Price shall
            be determined in good faith by the Parties based upon (1) quotes
            from Dealers in energy contracts; and/or (2) quotes from Brokers in
            energy contracts. Each Party may obtain up to a maximum of four
            quotes which must be provided to the other Party no later than
            twenty-two Business Days following the first Business Day on which
            the Market Disruption Event occurred or existed. These quotes shall
            reflect transacted prices. The Floating Price for the affected
            Trading Day shall equal a simple average of the quotes obtained and
            provided by the Parties consistent with the provisions of this
            Section 38. Each Party providing quote(s) to the other Party also
            shall

            identify to that other Party the Dealer(s) and/or the Broker(s) who
            provided each of the quotes to allow verification.

            "Determination Period" means each calendar month during the term of
            the relevant transaction; provided that if the term of the
            transaction is less than one calendar month the Determination Period
            shall be the term of the transaction. "Market Disruption Event"
            means, with respect to an index, any of the following events (the
            existence of which shall be determined in good faith by the
            Parties): (a) the failure of the index to announce or publish
            information necessary for determining the Floating Price; (b) the
            failure of trading to commence or the permanent discontinuation or
            material suspension of trading in the relevant options contract or
            commodity on the exchange or market acting as the index; (c) the
            temporary or permanent discontinuance or unavailability of the
            index; (d) the temporary or permanent closing of any exchange acting
            as the index; or (e) a material change in the formula for or the
            method of determining the Floating Price.

            "Trading Day" means a day in respect of which the relevant price
            source published the relevant price or would have published the
            relevant price but for the Market Disruption Event.

     38.3   Calculation of Floating Price. For the purposes of the calculation
            of a Floating Price, all numbers shall be rounded to three (3)
            decimal places. If the fourth (4th) decimal number is five (5) or
            greater, then the third (3rd) decimal number shall be

            increased by one (1), and if the fourth (4th) decimal number is less
            than five (5), then the third (3rd) decimal number shall remain
            unchanged.

     38.4   Corrections. For the purposes of determining the relevant prices for
            any day, if the price published or announced on a given day and used
            or to be used to determine the relevant price is subsequently
            corrected and the correction is published or announced by the person
            responsible for that publication or announcement, either Party may
            notify the other Party of (i) that correction and (ii) the amount
            (if any) that is payable as a result of that correction. If a Party
            gives notice that an amount is so payable, the Party that originally
            either received or retained such amount will pay such amount
            consistent with the provisions of this Section 38.4. The amount that
            is payable as a result of the correction shall be included in the
            billing cycle in which the notice of the correction is provided.

39.  AMENDMENT:

     39.1   This Agreement may be amended upon the submission to FERC and
            acceptance by FERC of that amendment. The Parties through the
            Executive Committee shall direct the filing of any amendments. The

            be amended, provided that the Parties possess the right to challenge
            any amendments at FERC and to exercise any applicable withdrawal
            rights under this Agreement.

     39.2   Unless otherwise stated in the amendment, all amendments shall apply
            only to new transactions entered into or agreed to on or after the
            effective date of the amendment. Preexisting agreements and

                                     NETTING

     Each Party that executes this Exhibit A to the Agreement agrees to net
payments for transactions under WSPP Service Schedule A, B, and C with any other
Party or Parties which also have agreed to net payments by executing a copy of
this Exhibit A. The Party executing this Exhibit A shall indicate below when it
desires that its agreement to net becomes effective. A Party agreeing to net
under this Exhibit A shall comply with the provisions of Section 28.2 of the
Agreement. Defined terms used herein are as defined in the WSPP Agreement.
Netting shall be done in accordance with the following provision:

            If the Purchaser and Seller are each required to pay an amount on
            the payment due date in the same month for transactions under the
            Agreement or Confirmation Agreement, then such amounts with respect
            to each Party will be aggregated and the Parties will discharge
            their obligations to pay through netting, in which case the Party
            owing the greater aggregate amount will pay to the other party the
            difference between the amounts owed consistent with the payment
            times in Section 9.2 of the Agreement, unless the Parties have
            otherwise agreed to a different payment time as allowed by the
            Agreement. Each Party reserves to itself all rights, set-offs,
            counterclaims and other remedies and/or defenses to which it is or
            may be entitled, arising from or out of the Agreement. All
            outstanding payments between the Parties which are to be netted
            pursuant to this Exhibit A for transactions under WSPP Service
            Schedule A, B, and C shall be offset against each other or set off
            or recouped therefrom.

     A.   Informal Mediation. WSPP members with a dispute or a potential dispute
          involving transactions under the WSPP Agreement may request
          non-binding, informal mediation by contacting the WSPP's General

          this Informal Mediation for it to become effective. After this
          contact, a telephonic conference call will be arranged among the
          affected WSPP members and the WSPP's General Counsel, the Chairman of
          the Operating Committee, and/or some other independent and
          knowledgeable person requested by the Chairman of the Operating
          Committee to participate. The purpose of the conference call will be
          to discuss the issues and to have an independent person or persons
          state their views. Best efforts will be made to set up this conference
          call within five Business Days after the WSPP's General Counsel is
          contacted subject to accommodating the schedules of all involved. This
          Informal Mediation shall be considered as satisfying the Mediation

          WSPP Representative shall allow at least one person suggested by each
          Party to be added to the list of Mediators. A brief personal history
          of each person on the list of potential mediators shall be provided to
          the Parties, with that history showing the person's employment over
          the last five years and any other relevant facts. The WSPP

          use best efforts to expedite this process.

     E.   Location for the Formal Mediation. The Parties shall agree on a
          location for the Mediation. If the Parties fail to reach agreement,

          which shall not be more than twenty-one days after the notice
          initiating the Mediation is received after consultation with the
          Parties and any Mediator.

     G.   Conduct of the Formal Mediation. The Mediator shall have the ability
          to conduct the Mediation in any manner which the Mediator believes is
          appropriate to facilitate resolution of the dispute. Each Party shall
          have at least one representative with the authority to settle the
          dispute present at the Mediation. The Mediation shall be private and
          confidential and the Mediator shall have the authority to exclude any
          person not directly involved unless the Parties agree otherwise in
          writing. At the Mediation, each Party shall have the right to make a
          brief presentation of its case and to question the other Party. Each
          Party also may be represented by counsel.

     H.   Replacement of the Mediator. If the Mediator resigns, withdraws or is
          no longer able to serve, then the Parties shall have two Business Days
          in which to agree on a new Mediator. If the Parties are unable to
          agree within such time, the WSPP Representative shall appoint a
          replacement Mediator from the list used to select the first Mediator

B-1  PARTIES:

     This Service Schedule is agreed upon as part of this Agreement by the
     Parties.

B-2  PURPOSE:

     The purpose of this Service Schedule is to define additional specific
     procedures, terms, and conditions for requesting and providing Unit
     Commitment Service.

B-3  TERMS:

     B-3.1  A Party may schedule Unit Commitment Service from another Party by

            statutory requirements and contractual commitments including the
            Agreement and any applicable Confirmation Agreement. Once an
            agreement is reached, then the obligation for Unit Commitment
            Service becomes a firm commitment, for both Parties, for the agreed
            capacity and terms.

     B-3.2  Unless otherwise mutually agreed by the Parties involved in a Unit
            Commitment Service transaction, the terms set forth in this Service
            Schedule B shall govern such transaction.

                               SERVICE SCHEDULE C

                  FIRM CAPACITY/ENERGY SALE OR EXCHANGE SERVICE
                  ---------------------------------------------

C-1  PARTIES:

     This Service Schedule is agreed upon as a part of this Agreement by the
     Parties.

C-2  PURPOSE:

     The purpose of this Service Schedule is to define additional specific
     procedures, terms, and conditions for requesting and providing Firm
     Capacity/Energy Sale or Exchange Service.

C-3  TERMS:

     C-3.1  A Party may schedule Firm Capacity/Energy Sale or Exchange Service
            from another Party by mutual agreement; provided, however, that each
            Party shall be the sole judge as to the extent to and the conditions
            under which it is willing to provide or receive such service
            hereunder consistent with statutory requirements and contractual
            commitments including the Agreement and any applicable Confirmation
            Agreement. Once an agreement is reached, then the obligation for
            Firm Capacity/Energy Sale or Exchange Service becomes a firm
            commitment, for both Parties, for the agreed service and terms.

     C-3.2  Unless otherwise agreed between the Purchaser and the Seller, all
            transactions shall be prescheduled, subject to any conditions agreed
            to by schedulers.

     C-3.3  Firm capacity transactions shall include buying, selling, or
            exchanging capacity between Parties with or without associated
            energy. Firm capacity is deemed a capacity sale from the Seller's

            capacity reserves.

     C-3.4  Firm energy transactions shall include buying, selling, or
            exchanging firm energy between Parties. Subject to mutual agreement,
            firm energy is deemed a quantity of energy the Seller has agreed to
            sell and deliver and the Purchaser has agreed to buy within a
            specified time period.

     C-3.5  Purchaser shall arrange purchases directly with Sellers.

     C-3.6  The price for Firm Capacity/Energy Sale or Exchange Service shall be
            mutually agreed to in advance between Seller and Purchaser and shall
            not be subject to the rate caps specified in Section C-3.7 in either
            of the following two circumstances:

            (1)  where the Seller is a FERC regulated public utility and that
                 Seller has been authorized to sell power like that provided for
                 under this Service Schedule at market-based rates; or

            (2)  where the Seller is not a FERC regulated public utility.

            A Party is a FERC regulated public utility if it is a "public
            utility" as defined in Section 201(e) of the Federal Power Act, 16
            U.S.C. Section 824(e).

     C-3.7  Except as provided for in Section C-3.6, the price shall not exceed

            highest demand experienced on any day in the seven-day period.
            Exchange ratios among such Parties shall be as mutually agreed
            between the Purchaser and the Seller, but shall not exceed the ratio
            of 1.5 to 1.0. The Seller's forecasted Incremental Cost discussed
            above also may include any transmission and/or ancillary service
            costs associated with the sale, including the cost of any
            transmission and/or ancillary services that the Seller must take on
            its own system. Any such transmission and/or ancillary service
            charges shall be separately identified by the Seller to the
            Purchaser for transactions under this Schedule including exchanges.
            The transmission and ancillary service rate ceiling shall be
            available through the WSPP's Hub or homepage. Any such transmission
            service (and ancillary services provided in conjunction with such
            transmission service) by Seller shall be provided pursuant to any
            applicable transmission tariff or agreement, and the rates therefore
            shall be consistent with such tariff or agreement.

     C-3.8  Firm Capacity/Energy Sale or Exchange Service shall be interruptible
            only if the interruption is: (a) within the recall time or allowed
            by other applicable provisions governing interruptions of service
            under this Service Schedule mutually agreed to by the Seller and the
            Purchaser, (b) due to an Uncontrollable Force as provided in Section
            10 of this Agreement; or (c) where applicable, to meet Seller's
            public utility or statutory obligations to its customers. If service
            under this Service Schedule is interrupted under Section C-3.8(a) or
            (b), neither Seller nor Purchaser shall be obligated to pay any
            damages under this Agreement or Confirmation Agreement. If service
            under this Service Schedule is interrupted for any reason

 ARTICLE 1 
 COMMITMENTS 
  
 1.1. The
Revolving Facility and the Swing Line Facility. 
  
 (a) Subject to the terms and conditions of this Agreement, (i) each Lender severally agrees to make Revolving Loans to the Borrowers (except for Swing Line Loans, which shall be extended only by the Swing Line
Lender), with the maximum amount of each Lender’s obligation being equal to such Lender’s Percentage of the Commitment Amount; and (ii) as set forth more fully in Section 1.1(b) below, the Swing Line Lender will make Swing Line Loans to
the Borrowers. Revolving Loans, including Swing Line Loans, shall bear interest and be payable in accordance with the terms and provisions of the Notes; 
  
 (b) Subject to the terms and conditions of this Agreement, the Swing Line Lender shall make swing line loans (each, a “Swing Line
Loan” and collectively, the “Swing Line Loans”) to the Borrowers from time to time during the Swing Line Commitment Period, in the aggregate principal amount at any one time outstanding not to exceed the Swing Line Commitment Amount;
provided, however, that at no time may the aggregate outstanding principal amount of the Swing Line Loans, plus the aggregate outstanding principal amount of Revolving Loans (including the Dollar Equivalent Amount of the aggregate face amount of all
Letters of Credit outstanding) exceed the lesser of the Revolving Facility Commitment Amount and the Asset Coverage Limit. During the Swing Line Commitment Period, the Borrowers may use the Swing Line Commitment by borrowing, repaying Swing Line
Loans in whole or in part, and reborrowing, all in accordance with the terms of this Agreement. At the request of the Swing Line Lender, and on and as of each Wednesday throughout the Loan term if, as of such Wednesday, Swing Line Outstandings shall
exceed Five Million and No/100 Dollars ($5,000,000.00), in the aggregate, the Administrative Agent may, at any time, on behalf of the Borrowers (which hereby irrevocably direct the Administrative Agent to act on their behalf) request each Lender
having a Percentage of the Revolving Facility, including the Swing Line Lender, to make, and each such Lender, including the Swing Line Lender, shall make an advance under the Revolving Facility, in an amount equal to such Lender’s Percentage
of the Revolving Facility Commitment Amount, of the amount of the Swing Line Outstandings as of the date such request is made. In such event, each such Lender shall make the requested proceeds available to the Administrative Agent for the account of
the Swing Line Lender in accordance with the funding provisions set forth in this Agreement. The proceeds of Revolving Loans advanced pursuant to this Section 1.1(b) shall be immediately applied to repay the Swing Line Outstandings. 
  
 1.2. Use of Proceeds. The Loans shall be
used by the Borrowers only for the following purposes: (i) to refinance certain existing indebtedness of the Borrowers; (ii) to finance any Permitted Merger or Acquisition; and (iii) to finance working capital requirements and general corporate
needs. Each Borrower agrees that it will not use or permit the Loan proceeds to be used for any other purpose without the prior written consent of the Administrative Agent. 
  
 1.3. Maximum Advances. Notwithstanding any term or provision of this Agreement or any
other Loan Document to the contrary, it is understood and agreed that in no event whatsoever shall the Lenders be obligated to advance any amount or issue any Letters of Credit pursuant hereto if such advance or the issuance of such Letter of Credit
would cause the aggregate amount of outstanding Loans (including Swing Line Outstandings), plus the Dollar Equivalent Amount of the aggregate face amount of all outstanding Letters of Credit, to exceed the following amounts: 
  
 (a) as to the Revolving Facility, the lesser of the
Revolving Facility Commitment Amount and the Asset Coverage Limit; 
  

 18 

 (b) as to the Swing Line Facility, the lesser of the Swing Line Facility Commitment
Amount and the Asset Coverage Limit. 
  
 If at any time (a) the outstanding
principal balance of the Revolving Facility (including the maximum Dollar Equivalent Amount of the aggregate face amount of all outstanding Letters of Credit, plus Swing Line Outstandings) shall exceed the lesser of the Revolving Facility Commitment
Amount and the Asset Coverage Limit, or (b) the aggregate amount of all Swing Line Outstandings shall exceed the lesser of the Swing Line Facility Commitment Amount and the Asset Coverage Limit (such excess, in either of the foregoing circumstances,
being referred to herein as an “Asset Coverage Deficiency”), the Borrowers shall immediately make a principal payment in the amount of the Asset Coverage Deficiency. 
  
 1.4. Advances. 
  
 (a) Agreement to Advance and Readvance; Procedure. So long as no Event of Default shall have occurred and be continuing, and no
act, event or condition shall have occurred and be continuing which with notice or the lapse of time, or both, shall constitute an Event of Default, and subject to the terms and provisions of this Agreement, the Lenders (and the Swing Line Lender,
as the case may be) shall advance and readvance the proceeds of the Revolving Facility and the proceeds of the Swing Line Facility from time to time in accordance with this Agreement. Requests for advances with respect to the Revolving Facility
shall be in the form of Exhibit 1 hereto, and requests for advances with respect to the Swing Line Facility shall be in the form of Exhibit 1(a) hereto. Requests for advances may be made via facsimile on any
given Business Day if the Borrowers provide the Administrative Agent, in advance, with a written list of the names of the specific officers authorized to request disbursements by facsimile. Upon request by the Administrative Agent, the Borrowers
shall confirm in an original writing each facsimile request for advance made by any Borrower. Notwithstanding the foregoing, (a) the Lenders shall have no obligation to make any advance with respect to the Revolving Facility after the Maturity Date;
and (b) the Swing Line Lender shall have no obligation to make any advance with respect to the Swing Line Facility after the Swing Line Termination Date. 
  
 (b) The Borrowers hereby authorize the Administrative Agent, on any Business Day, to transfer funds from the Collateral Account (if then
in effect) or any other designated account of the Borrowers to pay down the Obligations and to make advances available to the Borrowers to cover shortages or overdrafts in the Collateral Account (if then in effect), the Borrowers’ operating
account or such other designated account of the Borrowers. All such transfers shall be made pursuant to the Administrative Agent’s standard sweep-to-line account agreements and shall be subject to the availability of Loan proceeds under the
Facility (with respect to advances) and the availability of funds in the Collateral Account (if then in effect) or such other designated account of the Borrowers (with respect to paydowns). The Administrative Agent may, in its discretion,
make such transfers, but shall have no liability for its failure or refusal to do so. 
  
 (c) Interest Rate Election; Certain Advance Procedures and Limits. Amounts advanced in connection with the Loan shall bear interest
either on a Base Rate basis or LIBOR basis, as more fully set forth in the Notes and in the exhibits attached to this Agreement, except that the Swing Line Loans shall only be made available to the Borrowers on a Base Rate basis. Advances bearing
interest on a Base Rate basis shall be in minimum and incremental amounts of One Hundred Thousand and No/100 Dollars ($100,000.00), and shall be made available on a same-day basis, if requested by 12:00 Noon Washington, D.C. time on a Business Day.
Advances bearing interest on a LIBOR basis shall also be in minimum and incremental amounts of One Hundred Thousand and No/100 Dollars 

  

 19 

 
($100,000.00), and shall be made available not less than two (2) Business Days nor more than five (5) Business Days after request therefor. The
Borrowers’ right to request LIBOR based interest, as well as certain additional terms, conditions and requirements relating thereto, are set forth in the Notes and in the exhibits attached to this Agreement, and each Borrower expressly
acknowledges and consents to such additional terms and provisions. In no event whatsoever shall there be more than six (6) LIBOR funding segments remaining unpaid and outstanding at any time. 
  
 1.5. Additional Mandatory Payments. In addition to all
other sums payable by the Borrowers pursuant to any of the Notes, this Agreement or any other Loan Document, the Borrowers shall also make mandatory payments on the Notes (applied first to Swing Line Outstandings (if any), and then to amounts
outstanding under the Revolving Facility, as provided herein below), upon the occurrence of any Excess Cash Event. Notwithstanding the foregoing, no mandatory payment shall be due and payable unless the Net Cash arising from any Excess Cash Event
occurring in any fiscal year, when aggregated with all other Excess Cash Events occurring during fiscal year, exceeds the Annual Excess Cash Limitation, in which event the amount of such mandatory payment shall be equal to the amount by which the
Net Cash arising from such Excess Cash Event exceeds the Annual Excess Cash Limitation; it being understood and agreed, however, that no mandatory payments shall be required to reduce any present or future principal amount(s) subject to one or more
interest rate swap agreements entered into in accordance with this Agreement. 
  
 1.6. Field Audits. The Administrative Agent shall have the right at any time and in its sole discretion to conduct field audits with respect to the Collateral and each Borrower’s accounts
receivable, inventory, business and operations. All field audits shall be at the cost and expense of the Borrowers; it being understood and agreed that, in the absence of an Event of Default, the Borrowers’ maximum liability for field audit
costs and expenses shall be limited to the costs and expenses of only one (1) field audit conducted during any twenty-four (24) month period (unless the Administrative Agent shall conduct a field audit pursuant to Section 1.10 of this Agreement in
connection with the joinder of a new “Borrower” hereunder which has Receivables of the Dollar Equivalent Amount of Ten Million and No/100 Dollars ($10,000,000.00) or more as of the effective date of its acquisition by a Borrower or joinder
to this Agreement (whichever is earlier), in which event the Borrowers shall be liable for the costs and expenses of such field audit as well). Any and all field audits conducted following an Event of Default shall be at the Borrowers’ cost and
expense, with the foregoing limitation on maximum costs and expense being inapplicable. 
  
 1.7. Certain Fees. In addition to principal, interest and other sums payable under the Notes, the Borrowers shall pay the following fees: 
  
 (a) Upfront Fees. Simultaneously with the execution
of this Agreement, the Borrowers shall pay to the Administrative Agent, for the benefit of all Lenders pro-rata based on each Lender’s Percentage, a Loan upfront fee (the “Upfront Fee”) in an aggregate amount equal to one-quarter
percent (.25%) of the Revolving Facility Commitment Amount as of the Restatement Date. Additionally, the Borrowers shall pay to the Administrative Agent for the account of each Incremental Revolving Facility Lender, an upfront fee (an
“Incremental Revolving Facility Upfront Fee”) for the Incremental Revolving Facility Commitment made by such Incremental Revolving Facility Lender pursuant to this Agreement in an amount equal to one-quarter percent (.25%) of the
Incremental Revolving Facility Commitment Amount of such Incremental Revolving Facility Lender. The Incremental Revolving Facility Upfront Fee shall be due and payable in full on the effective date of such Incremental Revolving Facility Commitment.

  
 (b) Commitment Fee. So long as any
amounts remain outstanding in connection with the Facility, or the Lenders have any obligation to make any advance in connection 

  

 20 

 
therewith, the Borrowers agree to pay to the Administrative Agent for the benefit of all Lenders pro-rata based on each Lender’s Percentage, the
Revolving Facility Commitment Fee, calculated on the difference between (i) the Revolving Facility Commitment Amount, and (ii) the sum of the average daily outstanding principal balance of the Revolving Facility and the Swing Line Facility during
the applicable quarter, plus the Dollar Equivalent Amount of the aggregate face amount of all Letters of Credit at any time outstanding during the applicable quarter. The Revolving Facility Commitment Fee shall be calculated on the basis of the
actual number of days elapsed and a three hundred sixty (360) day year, shall be due for any quarter during which the Lenders have any obligation in connection with the Facility, and shall be payable in arrears, commencing on March 31, 2004 and
continuing on the last Business Day of every third (3rd) calendar month thereafter for so long as this Agreement remains in effect. 
  
 (c) Administrative Agent Fees. The Borrowers shall pay to the Administrative Agent, for its own account, (i) a loan administration
fee (the “Administration Fee”), and (ii) a loan arrangement fee (the “Arrangement Fee”), as more fully described in the Arrangement Fee Letter Agreement. The Administration Fee shall be due and payable, in advance, as follows:
(y) Fifty Thousand and No/100 Dollars ($50,000.00) on the Restatement Date; and (z) Seventy-five Thousand and No/100 Dollars ($75,000.00) on each anniversary of the Restatement Date. The Arrangement Fee shall be due and payable as and when specified
in the Arrangement Fee Letter Agreement. 
  
 (d)
Letter of Credit Fees. The Borrowers shall pay any and all Letter of Credit fees as and when such fees become due and payable pursuant to this Agreement. 
  
 (e) Out-of-Pocket Fees and Expenses. The Borrowers shall be liable for and shall timely pay all
reasonable out-of-pocket costs and expenses (including reasonable attorneys’ fees and expenses of counsel for the Administrative Agent, and of other special and local counsel and other experts, if any, engaged by the Administrative Agent) from
time to time incurred by the Administrative Agent in connection with the administration and/or preservation of rights in and enforcement of this Agreement, the other Loan Documents and the transactions contemplated by this Agreement. Without
limiting the generality of the foregoing, the Borrowers shall be liable for all reasonable out-of-pocket costs and expenses associated with any and all amendments, waivers and/or consents relating to any of the Facilities. 
  
 1.8. Increases to the Revolving Facility Commitment
Amount. 
  
 (a) The Borrowers may,
by written notice to the Administrative Agent from time to time after the Restatement Date, request Incremental Revolving Facility Commitments in an amount not to exceed the Uncommitted Incremental Revolving Facility Commitment Amount from one or
more Incremental Revolving Facility Lenders, which may include any existing Lender; provided that each Incremental Revolving Facility Lender, if not already a Lender hereunder, shall be subject to the approval of the Administrative Agent
(which approval shall not be unreasonably withheld). Each such notice shall set forth (i) the amount of the Incremental Revolving Facility Commitments being requested (which shall be in minimum increments of One Million and No/100 Dollars
($1,000,000.00) and a minimum amount of Five Million and No/100 Dollars ($5,000,000.00), or equal to the Uncommitted Incremental Revolving Facility Commitment Amount) and (ii) the date on which such Incremental Revolving Facility Commitments are
requested to become effective (which shall not be less than ten (10) Business Days nor more than sixty (60) days after the date of such notice). Any Revolving Loan made or to be made pursuant to an Incremental Revolving Facility Commitment shall (A)
constitute a Revolving Loan made pursuant to this Agreement, (B) be deemed advanced under the Revolving Facility, (C) bear interest and be repaid in accordance with the terms and provisions of this Agreement applicable to advances made under the
Revolving Facility, without preference or priority, (D) be secured by the 

  

 21 

 
Collateral on a pari passu basis, and (E) be subject to all other terms and provisions of this Agreement applicable to Revolving Loans and advances thereof.

  
 (b) The Borrowers and each Incremental
Revolving Facility Lender shall execute and deliver to the Administrative Agent an Incremental Revolving Facility Assumption Agreement and such other documentation as the Administrative Agent shall reasonably specify to evidence the Incremental
Revolving Facility Commitment of such Incremental Revolving Facility Lender. The Administrative Agent shall promptly notify each Lender as to the effectiveness of each Incremental Revolving Facility Assumption Agreement. Each of the parties hereto
hereby agrees that, upon the effectiveness of any Incremental Revolving Facility Assumption Agreement, this Agreement shall be deemed amended to the extent (but only to the extent) necessary to reflect the existence and terms of the Incremental
Revolving Facility Commitment evidenced thereby. 
  
 (c) Each of the parties hereto hereby agrees that the Administrative Agent may take any and all actions as may be reasonably necessary to ensure that, after giving effect to any Incremental Revolving Facility Commitment pursuant to this
Section 1.8, the outstanding Revolving Loans (if any) are held by the Lenders in accordance with their new pro rata Percentages. This may be accomplished at the discretion of the Administrative Agent (i) by requiring the outstanding Revolving Loans
to be prepaid with the proceeds to a new Revolving Facility borrowing, (ii) by causing the existing Lenders to assign portions of their outstanding Revolving Loans to Incremental Revolving Facility Lenders, (iii) by permitting the Revolving Facility
borrowings outstanding at the time of any increase in the Revolving Facility Commitment Amount pursuant to this Section 1.8 to remain outstanding until the last days of the respective Interest Periods therefor, even though the Lenders would hold
such Revolving Facility borrowings other than in accordance with their new pro rata Percentages, or (iv) by any combination of the foregoing. Any prepayment or assignment described in this subparagraph (c) shall be subject to indemnification by the
Borrowers pursuant to this Agreement, but otherwise without premium or penalty. 
  
 (d) Notwithstanding the foregoing, no Incremental Revolving Facility Commitment shall become effective, unless on the date of such
effectiveness, (i) no Event of Default shall have occurred and be continuing, and no act, event or condition shall have occurred or exist which with notice of the lapse of time, or both, would constitute an Event of Default, and (ii) the
Administrative Agent shall have received (A) a certificate dated such date and executed by the Chief Financial Officer or other duly authorized officer of the Borrowers, certifying that all of the representations and warranties set forth in Article
5 of this Agreement and in each of the other Loan Documents are true and correct in all material respects on and as of the date of the certificate with the same effect as though made on and as of such date (except to the extent that a representation
and warranty relates to an earlier date); (B) a duly executed Note, in form and substance acceptable to the Administrative Agent, which shall evidence the Revolving Loans to be made pursuant to the Incremental Revolving Facility Commitment; (C) UCC,
judgment and tax lien search results for the Borrowers, confirming that no intervening lien, claim or encumbrance (other than Permitted Liens) on any Collateral exists that would affect the legality, validity or priority of the liens in favor of the
Administrative Agent for the ratable benefit of the Lenders with respect to such Collateral; (D) the applicable Incremental Revolving Facility Assumption Agreement, duly executed by the parties thereto, together with such other documents,
instruments and/or agreements reasonably requested by the Administrative Agent; and (E) the applicable Incremental Revolving Facility Upfront Fee payable by the Borrowers to and for the account of the Incremental Revolving Facility Lender.

  
 1.9. Appointment of the Parent Company.
Each Borrower acknowledges that (i) the Lenders have agreed to extend credit to each of the Borrowers on an integrated basis for the purposes herein set forth; (ii) it is receiving direct and/or indirect benefits from each such extension of credit;
and 

  

 22 

 
(iii) the obligations of the “Borrower” or “Borrowers” under this Agreement are the joint and several obligations of each Borrower. To
facilitate the administration of the Loan, each Borrower hereby irrevocably appoints the Parent Company as its true and lawful agent and attorney-in-fact with full power and authority to execute, deliver and acknowledge on such Borrower’s
behalf, each Request for Advance and Certification, Quarterly Covenant Compliance Certificate and all other Loan Documents or other materials provided or to be provided to any of the Agents or Lenders pursuant to this Agreement or in connection with
the Loan. This power-of-attorney is coupled with an interest and cannot be revoked, modified or amended without the prior written consent of the Administrative Agent. On the Restatement Date, and from time to time promptly following the request of
the Administrative Agent, each Borrower shall execute, acknowledge and deliver to the Administrative Agent a form Power of Attorney confirming and restating the power-of-attorney granted herein. 
  
 1.10. Joinder of New Subsidiaries and Affiliates. Any
present or future subsidiary of any Borrower in which such Borrower now or hereafter owns, directly or indirectly, an ownership interest of greater than fifty percent (50%) shall, unless waived in writing by the Administrative Agent, execute and
deliver to the Administrative Agent (a) a Joinder Agreement in the form attached hereto as Exhibit 6 (a “Joinder Agreement”), pursuant to which such subsidiary or Affiliate shall (i) join in and become a party to this
Agreement and the other Loan Documents; (ii) agree to comply with and be bound by the terms and conditions of this Agreement and all of the other Loan Documents; and (iii) become a “Borrower” and thereafter be jointly and severally liable
for the performance of all the past, present and future obligations and liabilities of the Borrowers set forth herein and/or in any of the other Loan Documents; and (b) such other documents, instruments and agreements as may be reasonably required
by the Administrative Agent in connection therewith (including, without limitation, an opinion of counsel), in form and substance acceptable to the Administrative Agent in all respects. Unless the Administrative Agent elects not to do so, the
Administrative Agent shall perform a field audit of the accounts receivable, inventory, business and operations of any present or future subsidiary or Affiliate proposed to be joined as a “Borrower” hereunder, the cost and expense of which
shall be paid pursuant to Section 1.6. 
  
 ARTICLE 2 
 LETTERS OF CREDIT 
  
 2.1. Issuance. The Borrowers and Lenders acknowledge that from time to time the Borrowers may request that Citizens Bank issue or amend
Letter(s) of Credit. Subject to the terms and conditions of this Agreement, and any other reasonable requirements for letters of credit normally and customarily imposed by Citizens Bank, Citizens Bank agrees to issue such requested letters of
credit, provided that no Event of Default has occurred and is continuing, and no act, event or condition has occurred or exists which with notice or the passage of time, or both, would constitute an Event of Default. If any such Letter(s) of Credit
are issued by Citizens Bank, each of the Lenders shall purchase from Citizens Bank a risk participation with respect to such Letter(s) of Credit in an amount equal to such Lender’s Percentage of the Revolving Facility Commitment Amount.
Citizens Bank shall have no obligation to issue or renew any Letter of Credit which has an expiration date beyond the Maturity Date, unless the Borrowers shall have deposited with the Administrative Agent, concurrent with the issuance or renewal of
any such Letter of Credit, cash security therefor in an amount equal to the Dollar Equivalent Amount of the face amount of the Letter of Credit. Any request for a Letter of Credit shall be made by a Borrower submitting to the Administrative Agent an
Application and Agreement for Letter of Credit or Amendment to Letter of Credit (each being herein referred to as a “Letter of Credit Application”) on Citizens Bank’s standard form, at least three (3) Business Days prior to the date
on which the issuance or amendment of the Letter of Credit shall be required, which Letter of Credit Application shall be executed by an authorized officer of a Borrower, and be accompanied by such other supporting documentation and information as
the Administrative Agent may from time to time reasonably request. Each Letter of Credit 

  

 23 

 
Application shall be deemed to govern the terms of issuance of the subject Letter of Credit, except to the extent inconsistent with the terms of this
Agreement. It is understood and agreed that Letters of Credit shall not be issued for durations of longer than one (1) year. Any outstanding Letter of Credit may be renewed from time to time; provided that (i) at least sixty (60) days’ prior
written notice thereof shall have been given by the Borrower to the Administrative Agent; (ii) no default or Event of Default exists under the terms and provisions of the particular Letter of Credit or this Agreement; and (iii) if the renewal period
would expire after the Maturity Date, the Borrower shall have deposited with the Administrative Agent, concurrent with the renewal of any such Letter of Credit, cash security therefor in an amount equal to the Dollar Equivalent Amount of the face
amount of such Letter of Credit. Letters of Credit may be issued in U.S. Dollars or any Foreign Currency. 
  
 2.2. Amounts Advanced Pursuant to Letters of Credit. Upon the issuance of any Letter(s) of Credit (i) any amounts drawn pursuant
thereto shall be deemed advanced ratably under the Revolver Notes, shall bear interest and be payable in accordance with the terms of the Revolver Notes and shall be secured by the Collateral (in the same manner as all other sums advanced under the
Revolver Notes); and (ii) each Lender shall purchase from Citizens Bank such risk participations in the Letter(s) of Credit as shall be necessary to cause each Lender to share the funding obligations with respect thereto ratably in accordance with
its particular Percentage. It is expressly understood and agreed that all obligations and liabilities of the Borrowers to Citizens Bank in connection with any such Letter(s) of Credit shall be deemed to be “Obligations,” and the
Administrative Agent shall not be required to release its security interest in the Collateral until (i) all Notes and all other sums due to the Lenders in connection with the Loan have been paid and satisfied in full, (ii) all Letters of Credit have
been canceled or expired, and (iii) no Lender has any further obligation or responsibility to make additional Loan advances or issue additional Letters of Credit. Furthermore, in no event whatsoever shall Citizens Bank have any obligation to issue
any Letter of Credit which would cause the aggregate face amount of all then outstanding Letters of Credit issued for the benefit of any or all Borrowers to exceed the Dollar Equivalent Amount of Fifteen Million and No/100 Dollars ($15,000,000.00),
in the aggregate, at any time. 
  
 2.3. Letter of Credit
Fees. The Borrowers shall be jointly and severally liable for the payment of: (i) to the Lenders ratably, a Letter of Credit Fee, calculated on the average daily undrawn amount of each Letter of Credit issued or amended pursuant to
this Agreement, and on the basis of the actual number of days elapsed and a three hundred sixty (360) day year; and (ii) to the Administrative Agent, customary issuance and administrative charges (the “Letter of Credit Administration
Fees”). The Letter of Credit Fee shall be due and payable quarterly, in advance, on the date the Letter of Credit is issued or amended for the then current calendar quarter, and on the last day of each and every calendar quarter thereafter for
each succeeding calendar quarter during which such Letter of Credit shall remain issued or outstanding. Letter of Credit Administration Fees shall be due and payable simultaneously with the Administrative Agent’s issuance or amendment of the
particular Letter of Credit. 
  
 ARTICLE 3 
 SECURITY 
  
 3.1. Security Generally. As collateral security for the Loan and all other Obligations, the Borrowers hereby grant and convey to the
Administrative Agent, for the benefit of all of the Lenders ratably, a security interest in all of the following (collectively, the “Collateral”):

 ARTICLE 5 
 REPRESENTATIONS AND WARRANTIES 
  
 To induce the Lenders and Agents to enter into this Agreement, each Borrower jointly and severally represents, warrants, covenants and agrees as follows:

  
 5.1. Corporate Existence and
Qualification. Each Borrower is a corporation duly organized, validly existing and in good standing under the laws of its state of incorporation referenced in this Agreement (or any Joinder Agreement, as the case may be), with all
corporate power and authority and all necessary licenses and permits to own, operate and lease its properties and carry on its business as now being conducted, and as it may in the future be conducted. Each Borrower has only one (1) jurisdiction of
incorporation. Each Borrower is duly qualified and authorized to do business and is in good standing in each jurisdiction in which the nature of its activities or the character of its properties makes qualification necessary. 
  
 5.2. Corporate Authority; Noncontravention. The Parent
Company has been duly appointed by each other Borrower as its attorney-in-fact to execute and deliver this Agreement and all other Loan Documents, legally bind such Borrower to the terms and provisions of this Agreement, the other Loan Documents and
the Obligations, and otherwise perform, from time to time, such obligations of the Borrowers set forth in and/or contemplated by this Agreement, in each case for and on behalf of such Borrower as if such Borrower had duly executed and delivered this
Agreement and the other Loan Documents on its own behalf. The execution and delivery of this Agreement, the Notes and the other Loan Documents by each Borrower (or by the Parent Company on its own behalf and as attorney-in-fact for and on behalf of
each Borrower), and the performance of the obligations of each Borrower set forth in this Agreement, the Notes and the other Loan Documents (i) have been duly authorized by all necessary corporate and/or stockholder action of the Parent Company and
each of the other Borrowers; (ii) do not require the consent of any governmental body, agency or authority; (iii) will not violate or result in (and with notice or the lapse of time will not violate or result in) the breach of any provision of any
Borrower’s Articles/Certificate of Incorporation or By-laws, any material indenture, instrument, agreement or other undertaking to which any Borrower is a party or by which any Borrower is bound, or any order or regulation of any governmental
authority or arbitration board or tribunal; and (iv) except as permitted by the terms and provisions of this Agreement, will not result in the creation of a lien, charge or encumbrance of any nature upon any of the properties or assets of any
Borrower. When the Loan Documents are executed and delivered, they will constitute legal, valid and binding obligations of each Borrower, enforceable against each Borrower in accordance with their respective terms, subject to applicable bankruptcy,
insolvency and other similar laws affecting the rights of creditors generally. 
  
 5.3. Financial Position. The SEC filings of the Parent Company (with respect to itself and each of the Borrowers) present fairly the financial condition of the Borrowers as of the date thereof and
the results of the Borrowers’ operations for the periods indicated therein, were prepared in accordance 

  

 28 

 
with consistently applied accounting principles generally accepted in the United States of America, are true and accurate in all material respects, and are
not misleading in any material respect. All material liabilities, fixed or contingent, are fully shown or provided for on the referenced financial statements or the notes thereto as of the dates thereof. There has been no material adverse change in
the business, properties or condition (financial or otherwise) of the Borrowers, taken as a whole, since the date of the most recent SEC filing of the Parent Company. 
  
 5.4. Payment of Taxes. Each Borrower has filed all tax returns and reports required to be filed by it
with the United States Government and/or with all state and local governments, and has paid in full or made adequate provision on its books for the payment of all taxes, interest, penalties, assessments or deficiencies shown to be due or claimed to
be due on or in respect of such tax returns and reports, except to the extent that the validity or amount thereof is being contested in good faith by appropriate proceedings and the non-payment thereof pending such contest will not result in the
execution of any tax lien or otherwise jeopardize the Administrative Agent’s or the Lenders’ interests in any part of the Collateral. 
  
 5.5. Accuracy of Submitted Information; Omissions. As of the date furnished, all documents, certificates, information, materials and
financial statements furnished or to be furnished to any Lender or the Administrative Agent pursuant to this Agreement or otherwise in connection with the Loan (i) are true and correct in all material respects; (ii) do not contain any untrue
statement of a material fact; and (iii) do not omit any material fact necessary to make the statements contained therein or herein not misleading. No Borrower is aware of any fact which has not been disclosed to the Administrative Agent in writing
which materially adversely affects, or so far as any Borrower can now reasonably foresee, could reasonably be expected to have a material adverse effect on, (a) the properties, business, profit or condition (financial or otherwise) of the Borrowers,
taken as a whole, (b) the ability of any Borrower to perform its obligations set forth in this Agreement or in any other Loan Documents, or (c) any right or remedy available to the Administrative Agent and/or the Lenders pursuant to this Agreement
or any other Loan Document. 
  
 5.6. Government
Contracts. No notice of suspension, debarment or termination for default has been issued by the Government to any Borrower; no Borrower is a party to any pending suspension, debarment or termination for default; and no Borrower is the
target of any Government action or proceeding in connection with any Government Contract, involving allegations of fraud, dishonesty, malfeasance, misappropriation of funds or any other criminal activity. No Borrower is the subject of any cure
notice or show cause notice which could reasonably be expected to have a material adverse effect on the business, properties, profit or condition (financial or otherwise) of the Borrowers, taken as a whole. 
  
 5.7. No Defaults or Liabilities. No Borrower is in
default in any material respect in the performance of any obligation, covenant or condition contained in any material agreement to which it is a party. Additionally, except for the matters disclosed on Schedule 5.9 hereto, there
is no litigation, legal or administrative proceeding or investigation pending against any Borrower, and no litigation, legal or administrative proceeding or investigation has been threatened in writing against any Borrower, which has not been
disclosed to the Administrative Agent and/or the Lenders in writing and which involves amounts in excess of the Dollar Equivalent Amount of One Million and No/100 Dollars ($1,000,000.00) or which could reasonably be expected to prejudice the
Administrative Agent’s or any Lender’s rights under any Loan Document in any material respect. As of the Restatement Date, no judgment lien or tax lien has been filed against any Borrower for past due amounts which remain unpaid and
outstanding. 
  
 5.8. No Violations of Law.
No Borrower is in violation of any Applicable Laws in any material respect; no Borrower has failed to obtain any license, permit, franchise or other governmental authorization necessary to the ownership of its properties or to the conduct of its
business, and each 

  

 29 

 
Borrower has conducted its business and operations in compliance with all Applicable Laws in all material respects. 
  
 5.9. Litigation and Proceedings. Except for the matters
set forth on Schedule 5.9 attached hereto, no action, suit or proceeding against or affecting any or all Borrowers is presently pending, or to the knowledge of any Borrower, threatened, in any court, before any governmental
agency or department, or before any arbitration board or tribunal, which involves the possibility of any judgment or liability (which is not fully covered by insurance or appropriate reserves) in excess of the Dollar Equivalent Amount of (a) One
Million and No/100 Dollars ($1,000,000.00), in the aggregate, with respect to any Borrower, or (b) Ten Million and No/100 Dollars ($10,000,000.00), when aggregated with all other judgments then pending against any or all of the Borrowers. No
Borrower is in default with respect to any order, writ, injunction or decree of any court, governmental authority or arbitration board or tribunal. 
  
 5.10. Security Interest in the Collateral. Each Borrower is the sole legal and beneficial owner of the Collateral owned or purported
to be owned by it, free and clear of all liens, claims and encumbrances of any nature, except for the Permitted Liens and other liens expressly permitted by the terms and provisions of this Agreement and the other Loan Documents. 
  
 5.11. Principal Place of Business; Location of Books and
Records. Each Borrower maintains its principal place of business and the office where it keeps its books and records with respect to Accounts and contracts rights at the locations listed on Schedule 3 hereto. Set
forth on Schedule 5.11 hereto is a list of each Borrower’s business locations as of the Restatement Date, and all places where any of the Collateral is located. The locations set forth on Schedule 5.11
hereto denoted with an asterisk reflect all locations where fixed assets of a Borrower are valued in excess of the Dollar Equivalent Amount of Five Hundred Thousand and No/100 Dollars ($500,000.00). Each Borrower agrees to notify the Administrative
Agent in writing at least ten (10) days prior to any change in its principal place of business, or any change in the location of the office where it keeps its books and records with respect to Accounts and contract rights, or any change of or
addition to the locations where any Collateral is located. 
  
 5.12. Fiscal Year. Except as described on Schedule 5.12 hereto, each Borrower’s fiscal year ends on December 31. 
  
 5.13. Employee Benefit Plans. Each Borrower is in compliance, in all materials respects, with the
applicable provisions of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”), and the Code and the regulations and published interpretations thereunder. No ERISA Event has occurred or is reasonably expected to occur
that, when taken together with all other such ERISA Events, could reasonably be expected to have a material adverse effect on the properties, business, profits or condition (financial or otherwise) of the Borrowers, taken as a whole. The present
value of all benefit liabilities under each Plan (based on those assumptions used to fund such Plan) did not, as of the last annual valuation date applicable thereto, exceed by more than the Dollar Equivalent Amount of Three Million and No/100
Dollars ($3,000,000.00) the fair market value of the assets of such Plan, and the present value of all benefit liabilities of all underfunded Plans (based on those assumptions used to fund each such Plan) did not, as of the last annual valuation
dates applicable thereto, exceed by more than the Dollar Equivalent Amount of Three Million and No/100 Dollars ($3,000,000.00) the fair market value of the assets of all such underfunded Plans. 
  
 5.14. O.S.H.A. and Environmental Compliance. 

 
 (a) Each Borrower has duly complied in all material
respects with, and its facilities, business assets, property, leaseholds and equipment are in compliance in all material respects 

  

 30 

 
with, the provisions of the Federal Occupational Safety and Health Act (“O.S.H.A.”), the Environmental Protection Act, RCRA and all other
environmental laws which non-compliance with could result in a material adverse effect on the business, condition (financial or otherwise) or results of operations of any Borrower; and there have been no citations, notices, notifications or orders
of any such non-compliance issued to any Borrower or relating to its business, assets, property, leaseholds or equipment under any such laws, rules or regulations; 
  
 (b) each Borrower has been issued all required federal, state and local licenses, certificates and permits
necessary or appropriate in the operation of its facilities, businesses, assets, property, leaseholds and equipment, unless the failure to obtain any such license, certificate or permit would not have a material adverse effect on the business
condition (financial or otherwise) or results of operations of any Borrower; and 
  
 (c) (i) there are no visible signs of releases, spills, discharges, leaks or disposal (collectively referred to herein as
“Releases”) of Hazardous Substances at, upon, under or within any Real Property owned, or to the actual knowledge of any Borrower any premises leased, by any Borrower; (ii) there are no underground storage tanks or polychlorinated
biphenyls on any Real Property owned, or to the actual knowledge of any Borrower any premises leased, by any Borrower; (iii) no Real Property owned, or to the actual knowledge of any Borrower premises leased, by any Borrower has ever been used by
any Borrower (and to the best of each Borrower’s knowledge, any other person) as a treatment, storage or disposal facility for Hazardous Waste; and (iv) no Hazardous Substances are present on any Real Property owned, or to the actual knowledge
of any Borrower any premises leased, by any Borrower, except for such quantities of Hazardous Substances as are handled in all material respects in accordance with all applicable manufacturer’s instructions and governmental regulations, and as
are necessary or appropriate for the operation of the business of the Borrowers. Each Borrower, for itself and its successors and assigns, hereby covenants and agrees to indemnify, defend and hold harmless the Agents and Lenders from and against any
and all liabilities, losses, claims, damages, suits, penalties, costs and expenses of every kind or nature, including, without limitation, reasonable attorneys’ fees arising from or in connection with (i) the presence or alleged presence of any
Hazardous Substance or Hazardous Waste on, under or about any property of any Borrower (including, without limitation, any property or premises now or hereafter owned or leased by any Borrower), or which is caused by or results from, directly or
indirectly, any act or omission to act by any Borrower; and (ii) any Borrower’s violation of any environmental statute, ordinance, order, rule or regulation of any governmental entity or agency thereof (including, without limitation, any
liability arising under CERCLA, RCRA, HMTA or any Applicable Laws). 
  
 5.15. Intellectual Property. All patents, patent applications, trademarks, trademark applications, copyrights, copyright applications, tradenames, trade secrets and licenses necessary for the conduct of the business of
each Borrower are (i) owned or utilized by such Borrower, (ii) valid and, except with respect to licenses, have been duly registered or filed with all appropriate governmental authorities, and (iii) listed on Schedule 5.15 (a)
hereto. Except as disclosed in Schedule 5.15(a) hereto, there is no objection or pending challenge to the validity of any such patent, trademark, copyright, tradename, trade secret or license; no Borrower is aware of any grounds
for any such challenge or objection thereto which could reasonably be expected to have a material adverse effect on the business, properties, profit or condition (financial or otherwise) of the Borrowers, taken as a whole; except as disclosed in
Schedule 5.15(b) hereto, no Borrower pays any royalty to anyone in connection with any patent, trademark, copyright, tradename, trade secret or license; and each Borrower has the right to bring legal action for the infringement
of any such patent, trademark, copyright, tradename, trade secret or license. 
  

 31 

 5.16. Existing or Pending Defaults; Material Contracts. All Material Contracts are listed
on Schedule 5.16(a) hereto, and all Government Contracts (other than Subcontracts) which constitute Material Contracts and have a remaining term of twelve (12) months or longer are listed on Schedule 5.16(b)
hereto. Except as set forth on Schedule 5.9 attached hereto, no Borrower is aware of any pending or threatened litigation, or any other legal or administrative proceeding or investigation pending or threatened, against any
Borrower arising from or related to any Material Contract which could reasonably be expected to have a material adverse effect on (i) the business, condition (financial or otherwise) or results of operations of the Borrowers on a consolidated basis,
or (ii) any lien or security interest of the Administrative Agent or any Lender on, in or to any Collateral. 
  
 5.17. Leases and Real Property. As of the Restatement Date, no Borrower owns any real property. All material leases and other
agreements under which any Borrower occupies real property are in full force and effect and constitute legal, valid and binding obligations of, and are legally enforceable against, the Borrower party thereto and, to the Borrowers’ best
knowledge, are the binding obligations of and legally enforceable against, the other parties thereto. All necessary governmental approvals, if any, have been obtained for each such material lease or agreement, and there have been no threatened
cancellations thereof or outstanding material disputes with respect thereto. The landlord for the premises in which the Parent Company’s headquarters is located has subordinated (or expressly assumed terms, covenants and conditions of
subordination) for the benefit of the Administrative Agent, on terms and conditions reasonably satisfactory to the Administrative Agent, any landlord’s or lessor’s lien which may now or hereafter exist (whether by statute, contract or
otherwise) on any of the Collateral located at such premises. 
  
 5.18. Labor Relations. No Borrower is subject to any pending strikes, work stoppages, grievance proceedings, union organization efforts, employee disputes or other labor-related controversies pending, or to any
Borrower’s knowledge, threatened or reasonably anticipated which could reasonably be expected to have a material adverse effect on the business, properties, profit or condition (financial or otherwise) of the Borrowers, taken as a whole. Each
Borrower has complied and is in compliance in all material respects with all Applicable Laws relating to employment or the workplace, including, without limitation, provisions relating to wages, hours, collective bargaining, safety and health, work
authorization, equal employment opportunity, immigration, withholding, unemployment compensation, employee privacy and right to know. Except as set forth on Schedule 5.18 hereto, there are no collective bargaining agreements
between any Borrower and any of its employees. All material employment agreements between any Borrower and any of its employees and all material professional service agreements not terminable at will relating to the businesses or assets of any
Borrower in each case required to be disclosed in writing to the SEC pursuant to Applicable Law have been disclosed in accordance with Applicable Law. The consummation of the transactions contemplated hereby will not cause any Borrower to incur or
suffer any liability relating to, or obligation to pay, severance, termination or other similar payments to any person or entity. 
  
 5.19. Assignment of Government Contracts. No existing Government Contract of any Borrower (and no present or future interest of any
Borrower, in whole or in part, in, to or under any such Government Contract) is currently assigned, pledged, hypothecated or otherwise transferred to any person or entity (other than in favor of the Administrative Agent for the benefit of the
Lenders ratably). 
  
 5.20. Contribution Agreement.
The Contribution Agreement is in full force and effect, has not been modified, altered or amended in any respect whatsoever (other than to add a new Borrower party thereto from time to time or terminate the obligations set forth therein with respect
to any Borrower listed on Schedule 7.1(c) hereto from time to time), and no Borrower is in default thereunder. 
  

 32

the Parent Company to elect a majority of the board of directors of the Parent Company (or to otherwise exercise control of the Parent Company); (ii) at least fifty-one percent (51%) of all of the issued and outstanding voting stock of the Parent

outstanding capital stock of each other Borrower is owned by either the Parent Company or another Borrower, except as described on Schedule 5.21 hereto. 
  
 5.22. Solvency. Both prior to and after giving effect to the transactions contemplated by the terms and
provisions of this Agreement, (i) each Borrower (other than those Borrowers listed on Schedule 5.22 hereto) owned and owns property (including, without limitation, the Borrower’s rights under the Contribution Agreement)
whose fair saleable value is greater than the amount required to pay all of such Borrower’s Indebtedness (including contingent debts), (ii) each Borrower was and is able to pay all of its Indebtedness as such Indebtedness matures, and (iii)
each Borrower had and has sufficient capital available to carry on its business and transactions and all business and transactions in which it is about to engage. 
  
 5.23. Survival of Representations and Warranties. All representations and warranties made herein shall survive
the making of the Loan, and shall be deemed remade and redated as of the date of each request for an advance or readvance of any Loan proceeds, unless the Borrower is unable to remake and/or redate any such representation or warranty, discloses the
same to the Lenders in writing, and such inability does not constitute or give rise to an Event of Default. 
  
 ARTICLE 6

 ARTICLE 8

 COLLATERAL ACCOUNT 
  
 From and after the occurrence of an Event of Default, the Administrative Agent may request, and at the direction of the Required Lenders, the
Administrative Agent shall request, that the Borrowers deposit or cause to be deposited into a collateral account (the “Collateral Account”) designated by the 

  

 48 

 
Administrative Agent, all checks, drafts, cash and other remittances received by the Borrowers, and the Borrowers shall deposit such items for credit to the
Collateral Account within one (1) Business Day of the receipt thereof and in precisely the form received. Pending such deposit, the Borrowers will not commingle any such items of payment with any of their other funds or property, but will hold them
separate and apart. 
  
 The Borrowers hereby covenant and agree
that the Collateral Account shall secure the Obligations and hereby grants, assigns and transfers to or at the direction of the Administrative Agent, on behalf of the Lenders ratably, a continuing security interest in all of the Borrowers’
right, title and interest in and to the Collateral Account, whenever created or established. Subject to the terms of this Agreement or any other Loan Document, from and after the occurrence of an Event of Default, the Administrative Agent may apply
funds in the Collateral Account to any of the Obligations, including, without limitation, any principal, interest or other payment(s) not made when due, whether arising under this Loan Agreement and/or any other Loan Document, or any other
Obligation of the Borrowers, without notice to the Borrowers, without regard to the origin of the deposits in the account, the beneficial ownership of the funds therein or whether such Obligations are owed jointly with another or severally; the
order and method of such application to be in the sole discretion of the Administrative Agent, subject to the terms of this Agreement and the other Loan Documents. The Administrative Agent’s right to deduct sums due under the Loan Documents
from the Borrowers’ account(s) shall not relieve the Borrowers from their obligation to make all payments required by the Loan Documents as and when required by the Loan Documents, and the Administrative Agent shall not have any obligation to
make any such deductions or any liability whatsoever for any failure to do so. 
  
 ARTICLE 9 
 DEFAULT AND REMEDIES 
  
 9.1. Events of Default. Any one of the following events shall be considered an “Event of
Default”: 
  
 (a) if any Borrower shall fail
to pay any principal, interest or other sum owing on any of the Notes or any other Obligation when the same shall become due and payable, whether by reason of acceleration or otherwise, and such failure shall continue for five (5) days (with no
notice being required); 
  
 (b) if an Asset
Coverage Deficiency shall occur and the Borrowers shall fail, within five (5) days of the happening of such occurrence, without notice or demand therefor, to make a payment to the Administrative Agent in an amount equal to or greater than the Asset

satisfaction of the Administrative Agent, fully bonded, stayed, covered by insurance or covered by appropriate reserves; 
  
 (d) if any warranty or representation set forth herein or in any other Loan Document made by any Borrower or any other party to any of the
Loan Documents shall be misleading or untrue in any material respect when made or remade; 
  
 (e) if there shall be non-compliance with or a breach of Section 7.10(c) of this Agreement (for which there shall be no notice or cure
period); or if there shall be non-compliance with or a breach of any of the Affirmative Covenants or Negative Covenants (other than Section 7.10(c)) 

  

 49 

 
contained in this Agreement and, to the extent that such non-compliance and/or breach is reasonably capable of being cured, such non-compliance or breach
shall continue unremedied for fifteen (15) days after notice thereof from the Administrative Agent to the Borrowers; or if there shall be non-compliance with or a breach of any other covenants or agreements of any Borrower or any other person set
forth herein, in any of the Notes or in any other Loan Document, and such non-compliance or breach shall continue unremedied beyond any applicable notice and/or cure period therefor;

Borrowers listed on Schedule 7.1(c) hereto) shall be liquidated or dissolved or shall discontinue its business; (ii) a trustee or receiver is appointed for any Borrower or for all or a substantial part of its assets; (iii) any
Borrower makes a general assignment for the benefit of creditors; (iv) any Borrower files or is the subject of any insolvency proceeding or petition in bankruptcy, which in the case of an involuntary bankruptcy, remains undismissed for sixty (60)
days; (v) the Parent Company or any other Borrower (other than the Borrowers listed on Schedule 5.22 hereto and any other Borrower(s) whose insolvency, individually or collectively, could not reasonably be expected to have a
material adverse effect on the properties, business, profits or condition (financial or otherwise) of the Borrowers, taken as a whole) shall become insolvent or shall at any time fail generally to pay its debts as such debts become due; or (vi) any
governmental agency or bankruptcy court or other court of competent jurisdiction shall assume custody or control of the whole or any part of the assets of any Borrower; 
  
 (g) if any Borrower’s property or assets, including, without limitation, any deposit accounts, are
levied upon, attached or subject to any other enforcement proceeding, which is not fully bonded or stayed within ten (10) days thereof; 
  
 (h) the reorganization of any Borrower, without the prior written consent of the Administrative Agent; 
  
 (i) if any obligation of any Borrower for the payment of
borrowed money, which involves amounts in excess of the Dollar Equivalent Amount of Five Hundred Thousand and No/100 Dollars ($500,000.00), whether now existing or hereafter created, incurred or arising, becomes or is declared to be due and payable
prior to the expressed maturity thereof, whether such obligation is owed to a Lender or any other person; 
  
 (j) if any Borrower is in default under any contract or agreement, financial or otherwise, between such Borrower and any other person or
entity, involving amounts in excess of the Dollar Equivalent Amount of One Million and No/100 Dollars ($1,000,000.00), and the other party thereto commences exercise of its rights and remedies under such contract or agreement as a consequence of
such default; and/or 
  
 (k) if the Required
Lenders believe there is a material adverse change in the business, assets, properties, condition (financial or otherwise) of the Borrowers, in the aggregate. 
  

9.2. Remedies. Upon the occurrence of the Event of Default set forth in Section 9.1(f)(iv) of this Agreement, all commitments of
the Lenders hereunder shall automatically (and without further notice, demand or other action) terminate, and all principal, accrued and unpaid interest and all other Obligations shall automatically (and without further notice, demand or other
action) become immediately due and payable in full. Without limiting the foregoing, upon the occurrence of any Event of Default, the Administrative Agent, acting on behalf of the Lenders, may exercise any or all of the following remedies:

  
 (a) Withhold disbursement of all or any part
of the Loan proceeds; 
  

 50 

 (b) Terminate the Lenders’ obligation to make further disbursements of the Loan
proceeds; 
  
 (c) Declare all principal, interest
and other sums owing on the Obligations to be immediately due and payable without demand, protest, notice of protest, notice of default, presentment for payment or further notice of any kind; 
  
 (d) Without notice, redirect any and all of the
Borrowers’ deposits to the Collateral Account; 
  
 (e) Without notice, offset and apply against all or any part of the Obligations then owing by any Borrower to any Lender, any and all money, credits, stocks, bonds or other securities or property of any Borrower of any kind or nature
whatsoever on deposit with, held by or in the possession of any Lender in any capacity whatsoever, including, without limitation, any deposits with any Lender or any of its Affiliates, to the credit of or for the account of any Borrower. The
Administrative Agent and Lenders are authorized at any time to charge the Obligations against any Borrower’s account(s), without regard to the origin of deposits to the account or beneficial ownership of the funds. Any and all amounts obtained
by the Administrative Agent or any Lender pursuant to this subsection (e) shall be shared by all of the Lenders ratably, in accordance with each Lender’s Percentage; it being expressly acknowledged and agreed that each Lender, as well as the
Administrative Agent, shall be entitled to exercise the rights of set-off provided in this subsection (e) of this Section 9.2; 
  
 (f) Exercise all rights, powers and remedies of a secured party under the UCC and/or any other applicable law(s), including, without
limitation, the right to (i) require any Borrower to assemble the Collateral (to the extent that it is movable) and make it available to the Administrative Agent at a place to be designated by the Administrative Agent, and (ii) enter upon any
Borrower’s premises, peaceably by the Administrative Agent’s own means or with legal process, and take possession of, render unusable or dispose of the Collateral on such premises; each Borrower hereby agreeing not to resist or interfere
with any such action. The Administrative Agent agrees to give the Borrowers written notice of the time and place of any public sale of the Collateral or any part thereof, and the time after which any private sale or any other intended disposition of
the Collateral is to be made, and such notice will be mailed, postage prepaid, to the principal place of business of the Borrowers, at least ten (10) days before the time of any such sale or disposition. Each Borrower hereby authorizes and appoints
the Administrative Agent and its successors and assigns to (x) sell the Collateral, and (y) declare that each Borrower assents to the passage of a decree by a court of proper jurisdiction for the sale of the Collateral. Any such sale pursuant to (x)
or (y) above is to be made in accordance with the applicable provisions of the laws and rules of procedure of the Commonwealth of Virginia or other applicable law; and/or 
  
 (g) Proceed to enforce such other and additional rights and remedies as the Administrative Agent and/or
Lenders may have hereunder and/or under any of the other Loan Documents, or as may be provided by applicable law. 
  
 It is expressly understood and agreed that the Lenders and/or the Administrative Agent may exercise their respective rights under this Agreement or under
any other Loan Document without exercising the rights or affecting the security afforded by any other Loan Document, and it is further understood and agreed that the Administrative Agent may proceed against all or any portion of the Collateral in
such order and at such times as the Administrative Agent, in its sole discretion, sees fit; and each Borrower hereby expressly waives, to the extent permitted by law, all benefit of valuation, appraisement, marshaling of assets and all exemptions
under the laws of the Commonwealth of Virginia and/or any other state, district or territory of the United States. Notwithstanding the foregoing delegation of authority by the Lenders to the Administrative Agent, it is agreed that at any time
there are two (2) or 

  

 51 

 
fewer Lender parties to this Agreement, any Lender may request the Administrative Agent to commence enforcement action against the Borrowers and/or
Collateral upon an Event of Default. In this event, if the Administrative Agent fails or refuses to take enforcement action upon the request of a Lender, such Lender may itself commence appropriate enforcement action. Furthermore, if any Borrower
shall default in the performance when due of any of the provisions of this Agreement, the Administrative Agent, without notice to or demand upon the Borrowers (and without any grace or cure period) and without waiving or releasing any of the
Obligations or any default hereunder, under the Notes or under any other Loan Document, may (but shall be under no obligation to) perform the same for each Borrower’s account, and any monies expended in so doing shall be chargeable to the
Borrowers with interest, at a per annum rate equal to the Base Rate, plus the Base Rate Interest Margin, plus two percent (2%), and added to the indebtedness secured by the Collateral. 
  
 All sums paid or advanced by the Administrative Agent in connection with the foregoing or otherwise in connection with the
Loan, and all court costs and expenses of collection, including without limitation, reasonable attorneys’ fees and expenses (and fees and expenses resulting from the taking, holding or disposition of the Collateral) incurred in connection
therewith shall be paid by the Borrowers upon demand and shall become a part of the Obligations secured by the Collateral. The Borrowers agree to bear the expense of each lien search, property and judgment report or other form of Collateral
ownership investigation as the Administrative Agent, in its discretion, shall deem necessary or desirable to assure or further assure to the Lenders and/or the Administrative Agent their respective interests in the Collateral. 
  
 ARTICLE 10 
 THE AGENTS; AGENCY 
  
 10.1. Appointment. Each Lender hereby affirms its irrevocable appointment of Citizens Bank to act as Administrative Agent and KeyBank to act as Documentation Agent for each such Lender pursuant to the provisions of this
Agreement and the other Loan Documents, and affirms its irrevocable authorization given to the Agents to take such action, and exercise such powers and perform such duties as are expressly delegated to or required of the Agents by the terms hereof
or thereof, or are reasonably incidental thereto, including without limitation, executing documents on behalf of the Lenders, as agent. Citizens Bank affirms its agreement to act as Administrative Agent and KeyBank affirms its agreement to act as
Documentation Agent on behalf of the Lenders on the terms and conditions set forth in this Agreement and the other Loan Documents, subject to their right to resign as provided in Section 10.10. Each Lender agrees that the rights and remedies granted
to the Agents under this Agreement and the other Loan Documents shall be exercised exclusively by the Agents, and that no Lender shall have the right individually to exercise any such right or remedy, except to the extent expressly provided herein
or therein. 
  
 10.2. General Nature of Agents’
Duties. Notwithstanding anything to the contrary elsewhere in this Agreement or any other Loan Document: 
  
 (a) The Agents shall have no duties or responsibilities other than those expressly set forth in this Agreement and the other Loan
Documents, and no implied duties or responsibilities on the part of the Agents shall be read into this Agreement or any other Loan Document or shall otherwise exist. 
  
 (b) The duties and responsibilities of the Agents under this Agreement and the other Loan Documents shall be
mechanical and administrative in nature, and the Agents shall not have a fiduciary relationship in respect of any Lender, except with respect to funds or collateral any Agent receives on behalf of any Lender. 
  

 52 

 (c) Each Agent is and shall be solely the agent of the Lenders. Each Agent does not
assume, and shall not at any time be deemed to have, any relationship of agency or trust with or for, or any other duty or responsibility to, any Borrower or any other person (except only for its relationship as agent for, its express duties and
responsibilities as agent for, and its express duties and responsibilities to, the Lenders as provided in this Agreement and the other Loan Documents). 
  
 (d) Neither Agent shall be under any obligation to take any action hereunder or under any other Loan Document if such Agent believes in

 10.3. Exercise of Powers. 
  
 (a) The Agents shall have the authority to take any action
of the type specified in this Agreement or any other Loan Document as being within each Agent’s rights, powers or discretion, as it determines in its sole discretion, except as provided in subsection (b) below, and except as provided in any
other Loan Document which expressly requires the direction or consent of (i) the Required Lenders; or (ii) all of the Lenders, in either of which circumstances such Agent shall not take such action absent such direction or consent. Any action or
inaction pursuant to such direction or consent shall be binding on all of the Lenders.

Agreement or any other Loan Document without the consent or approval of the Required Lenders, or declare an Event of Default, provide formal written notice of default to any Borrower or exercise any rights or remedies against any Borrower without
the prior consent of the Required Lenders. Each Lender agrees that its decision to consent to or reject any request by the Administrative Agent for permission to declare an Event of Default, provide formal notice thereof to any Borrower and/or
exercise any rights or remedies arising by virtue of such default, shall be made as soon as reasonably practicable after the Lender has received all relevant information with respect to such request, but in all events within five (5) Business Days
of the receipt of such information; it being understood and agreed that, unless otherwise provided herein, the Administrative Agent shall exercise any and all rights and responsibilities on behalf of the Lenders in connection with an Event of
Default. Additionally, only with the consent or approval of all of the Lenders, the Administrative Agent may (a) extend the final maturity of the Loan or any Note, reduce the interest rate payable on or extend the time of payment for any installment
of principal, interest or fees payable in connection with the Loan, or issue Letters of Credit which would (i) have an expiration date beyond the Maturity Date, except as otherwise expressly provided in this Agreement, or (ii) cause the aggregate
outstanding amount of all such Letters of Credit issued to exceed the Dollar Equivalent Amount of Fifteen Million Dollars ($15,000,000); (b) except in connection with any Incremental Revolving Facility Commitment (as provided under Section 1.8 of
this Agreement), change the Percentage of the Commitment Amount of any Lender, (c) release all or a substantial portion of the Collateral, except in accordance with the provisions of any applicable Loan Document, (d) amend the definition of the
Required Lenders, (e) consent to the assignment or transfer by any Borrower of any of its rights or obligations hereunder, (f) amend, modify or waive any provisions of this Section 10.3, (g) change the manner of application by the Administrative
Agent of payments made under the Loan Documents, or (h) change the method of calculation used in connection with the computation of interest, commissions or fees. Each Lender agrees that its decision to approve or reject any request for an amendment
or waiver with respect to this Agreement shall be made as soon as reasonably practicable after the Lender has received all relevant information with respect to such request. 
  

 53 

 10.4. General Exculpatory Provisions. Notwithstanding anything to the contrary
elsewhere in this Agreement or any other Loan Document: 
  
 (a) Neither Agent, in its capacity as Agent (but not as a Lender), shall be liable for any action taken or omitted to be taken by it under or in connection with this Agreement or any other Loan Document, unless caused
by its own gross negligence or willful misconduct. 
  
 (b) Neither Agent shall be responsible for (i) the execution, delivery, effectiveness, enforceability, genuineness, validity or adequacy of this Agreement or any other Loan Document, (ii) any recital, representation, warranty, document,
certificate, report or statement in this Agreement or any other Loan Document, (iii) any failure of any Borrower or any Lender to perform any of their respective obligations under this Agreement or any other Loan Document, (iv) the existence,
validity, enforceability, perfection, recordation, priority, adequacy or value, now or hereafter, of any lien or encumbrance or other direct or indirect security afforded or purported to be afforded by any of the Loan Documents, or otherwise from
time to time, or (v) caring for, protecting, insuring or paying any taxes, charges or assessments with respect to any Collateral. 
  
 (c) Neither Agent shall be under any obligation to ascertain, inquire or give any notice relating to (i) the performance or observance of
any of the terms or conditions of this Agreement or any other Loan Document on the part of any Borrower, (ii) the business, operations, condition (financial or otherwise) or prospects of any Borrower, or (iii) except to the extent as may be set
forth in Article 9 hereof, the existence of any Event of Default. 
  
 (d) Neither Agent shall be under any obligation, either initially or on a continuing basis, to provide any Lender with any notices, reports or information of any nature, whether in its possession presently or
hereafter, except for such notices, reports and other information expressly required by this Agreement or any other Loan Document to be furnished by the Agent to such Lender. 
  
 10.5. Administration by the Agent. 
  
 (a) Each Agent may rely upon any notice or other communication of any nature (written or oral, including
telephone conversations, whether or not such notice or other communication is made in a manner permitted or required by this Agreement or any other Loan Document) purportedly made by or on behalf of the proper party or parties, and neither Agent
shall have any duty to verify the identity or authority of any person giving such notice or other communication. 
  
 (b) Each Agent may consult with legal counsel (including in-house counsel for such Agent), independent public accountants and any other
experts selected by such Agent from time to time, and neither Agent shall be liable for any action taken or omitted to be taken in good faith by it in accordance with the advice of such counsel, accountants or experts. 
  
 (c) Each Agent may conclusively rely upon the truth of the
statements and the correctness of the opinions expressed in any certificates or opinions furnished to such Agent in accordance with the requirements of this Agreement or any other Loan Document. Whenever either Agent shall deem it necessary or
desirable that a matter be proved or established with respect to any Borrower or any Lender, such matter may be established by a certificate of such Borrower or such Lender, as the case may be, and such Agent may conclusively rely upon such
certificate. 
  
 (d) Each Agent may fail or
refuse to take any action unless it shall be indemnified to its satisfaction from time to time against any and all amounts, liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses and disbursements of every
kind and nature which may be imposed on, incurred by or asserted against such Agent by reason of taking or continuing to take any such action; provided that no Lender shall be obligated to indemnify such Agent for any portion of such amounts,
liabilities, obligations, losses, damages, penalties, actions, judgments, 

  

 54 

 
suits, costs, expenses and disbursements resulting solely from the gross negligence or willful misconduct of such Agent, as finally determined by a court of
competent jurisdiction. 
  
 (e) Each Agent may
perform any of its duties under this Agreement or any other Loan Document by or through agents or attorneys-in-fact. Neither Agent shall be responsible for the negligence or misconduct of any agents or attorneys-in-fact selected by it with
reasonable care. 
  
 (f) Neither Agent shall be
deemed to have any knowledge or notice of the occurrence of any Event of Default (other than a default in the payment of regularly scheduled principal or interest), unless such Agent has received from a Lender or a Borrower a written notice
referring to this Agreement, describing the Event of Default, and stating that such notice is a “notice of default”. If either Agent receives such a notice, such Agent shall give prompt notice thereof to each Lender. 
  
 (g) Promptly after the Administrative Agent shall have
received the results of any field audit conducted pursuant to Section 1.6 of this Agreement, the Administrative Agent will forward such results to the Lenders. 
  

10.6. Lenders Not Relying on Agent or Other Lenders. Each Lender acknowledges as follows: 
  
 (a) Neither Agent nor any other Lender has made any
representations or warranties to it, and no act taken hereafter by either Agent or any other Lender shall be deemed to constitute any representation or warranty by such Agent or such other Lender to it. 
  
 (b) It has, independently and without reliance upon either
Agent or any other Lender, and based upon such documents and information as it has deemed appropriate, made its own credit and legal analysis and decision to enter into this Agreement and the other Loan Documents. 
  
 (c) It will, independently and without reliance upon either
Agent or any other Lender, and based upon such documents and information as it shall deem appropriate at the time, make its own decisions to take or not take action under or in connection with this Agreement and the other Loan Documents. 

 
 10.7. Indemnification. Each Lender agrees to
reimburse and indemnify each Agent and each Agent’s directors, officers, employees and agents (to the extent not reimbursed by the Borrowers, and without limitation of the obligation of the Borrowers to do so), ratably in accordance with each
Lender’s Percentage, from and against any and all amounts, losses, liabilities, claims, damages, expenses, obligations, penalties, actions, judgments, suits, costs and disbursements of every kind or nature (including the reasonable fees and
disbursements of counsel for each Agent or such other person in connection with any investigative, administrative or judicial proceeding commenced or threatened, whether or not either Agent or such other person shall be designated a party thereto)
that may at any time be imposed on, incurred by or asserted against such Agent or such other person as a result of this Agreement, any other Loan Document, any transaction from time to time contemplated hereby or thereby, or any transaction financed
in whole or in part or directly or indirectly with the proceeds of the Loan; provided that no Lender shall be obligated to indemnify such Agent or such other person for any portion of such amounts, losses, liabilities, claims, damages,
expenses, obligations, penalties, actions, judgments, suits, costs or disbursements resulting solely from the gross negligence or willful misconduct of the person seeking indemnity, as finally determined by a court of competent jurisdiction.

  

 55 

 10.8. Agent in its Individual Capacity; Agents’ Commitment. 
  
 (a) With respect to their commitments and the Obligations
owing to them, Citizens Bank and KeyBank shall have the same rights and powers under this Agreement and each other Loan Document as any other Lender, and may exercise the same as though they were not the Agents. The terms “Lender,”
“holders of Notes” and like terms shall include Citizens Bank and KeyBank in their individual capacities. Citizens Bank and KeyBank and their respective Affiliates may, without liability to account for, make loans to, accept deposits from,
acquire debt or equity interests in, act as trustee under indentures of and engage in any other business with any Borrower and any Affiliate of any Borrower, as though Citizens Bank and KeyBank were not the Agents hereunder. 
  
 (b) The Administrative Agent hereby agrees that it shall at
all times maintain, at a minimum, the lesser of (the “Agent’s Commitment”): 
  
 (i) a Ten Million and No/100 Dollar ($10,000,000.00) interest in the aggregate Commitment Amount; or 
  
 (ii) a Percentage of the Commitment Amount that is at least
equal to ten percent (10%). 
  
 In the event the Administrative Agent fails to
maintain the Agent’s Commitment, the Administrative Agent agrees to resign as the Administrative Agent hereunder, if requested by the Borrowers, pursuant to Section 10.10 of this Agreement; it being expressly acknowledged and agreed that the
Borrowers shall be third party beneficiaries of the Agent’s Commitment requirement set forth in this Section 10.8(b). 
  
 10.9. Holders of Notes. The Administrative Agent may deem and treat any Lender which is the payee of a Note as the owner and holder
of such Note for all purposes hereof unless and until written notice evidencing such transfer shall have been filed with the Administrative Agent. Any authority, direction or consent of any person who at the time of giving such authority, direction
or consent was a Lender shall be conclusive and binding on each present and subsequent holder, transferee or assignee of any Note or Notes payable to such Lender or issued in exchange therefor. 
  
 10.10. Successor Agent. Either Agent may resign at any
time by giving thirty (30) days prior written notice thereof to the Lenders and Borrowers, subject to appointment of a successor Agent (and such appointees acceptance of appointment) as below provided in this Section 10.10. Additionally, either
Agent may be removed for cause (i.e., for conduct constituting gross negligence or willful misconduct) by all of the Lenders (other than such Agent, if such Agent is then a Lender), or the Borrowers may request an Agent’s resignation pursuant
to Section 10.8(b), if removal or resignation, as applicable, is requested in writing (which wording must specifically identify the “cause” for removal), and ten (10) days’ prior written notice of removal or resignation is provided to
such Agent and Borrowers (or Lenders, if applicable). Upon any such resignation or removal, the Lenders shall appoint the other Agent as the successor Documentation Agent or Administrative Agent, as the case may be. All references to the
“Agents” in the Loan Documents shall be deemed to mean the person(s) acting as the Documentation Agent and Administrative Agent, and it is understood that it is possible that the same person may be acting in both capacities. If such other
Agent fails or refuses to accept such appointment within thirty (30) days after such notice of resignation or removal, then the retiring Agent shall, on behalf of the Lenders, immediately appoint, as its successor, another Lender; provided that such
Lender is a commercial bank or trust company organized under the laws of the United States of America or any State thereof and has a combined capital and surplus of at least One Billion and No/100 Dollars ($1,000,000,000.00). In such event, the
Agent’s resignation or removal shall not be effective until the 

  

 56 

 
successor Agent shall have accepted its appointment. Upon the acceptance by a successor Agent of its appointment as Agent hereunder, such successor Agent
shall thereupon succeed to and become vested with all of the properties, rights, powers, privileges and duties of the former Agent, without further act, deed or conveyance. Upon the effective date of resignation or removal of a retiring Agent, such
Agent shall be discharged from its duties under this Agreement and the other Loan Documents, but the provisions of this Agreement shall continue to be binding on and inure to its benefit as to any actions taken or omitted by it while it was Agent
under this Agreement. If for any reason, at any time, there is no Administrative Agent hereunder, then during such period, the Required Lenders shall have the right to exercise the Administrative Agent’s rights and perform its duties hereunder,
except that (i) all notices or other communications required or permitted to be given to the Administrative Agent shall be given to each Lender, and (ii) all payments to be made to the Administrative Agent shall be made directly to the Borrowers or
the Lender for whose account such payment is made. 
  
 10.11.
Additional Agents. If the Administrative Agent shall from time to time deem it necessary or advisable to engage other agents for its own protection in the performance of its duties hereunder or in the interests of the Lenders,
then the Administrative Agent and Borrowers shall execute and deliver a supplemental agreement and all other instruments and agreements necessary or advisable, in the opinion of the Administrative Agent, to constitute another commercial bank or
trust company, or one or more other persons approved by the Administrative Agent, to act as co-Agent or a separate agent with respect to any part of the Collateral, with such powers as may be provided in such supplemental agreement, and with the
power to vest in such bank, trust company or other person (as such co-Agent or separate agent, as the case may be), any properties, rights, powers, privileges and duties of the Administrative Agent under this Agreement or any other Loan Document.

  
 10.12. Calculations. Neither Agent shall
be liable for any calculation, apportionment or distribution of payments made by it in good faith. If such calculation, apportionment or distribution is subsequently determined to have been made in error, the sole recourse of any Lender to whom
payment was due but not made shall be to recover from the Lenders any payment in excess of the amount to which they are determined to be entitled, with interest thereon at the Federal Funds Rate, or, if the amount due was not paid by any Borrower,
to recover such amount from such Borrower, with interest thereon at the rate provided in the applicable Note. 
  
 10.13. Funding by the Administrative Agent. 
  
 (a) Except as otherwise provided in this Agreement, the Administrative Agent alone shall be entitled to make all advances in connection
with the Loan and shall receive all payments and other receipts relating to the Loan; it being understood, however, that the Administrative Agent has reserved the right not to advance any amounts to the Borrowers which the Administrative Agent has
not received from the Lenders. The Administrative Agent will notify each Lender of the date and amount of any requested advance, and if such notification is received by 1:00 p.m. Washington, D.C. time on any given Business Day, the Lenders shall
provide the required funds to the Administrative Agent no later than 4:00 p.m. Washington, D.C. time on such Business Day. At any time and from time to time upon the Administrative Agent’s request, the Administrative Agent and each Lender shall
pay to each other such amounts (the “Equalization Payments”) as may be necessary to cause each Lender to own its applicable Percentage of the Loan and otherwise implement the terms and provisions of this Agreement; it being understood that
each Lender shall be entitled to receive interest on amounts advanced by it only from the date of such Lender’s advance of funds. The obligation of the Administrative Agent and each Lender to make Equalization Payments shall not be affected by
a bankruptcy filing by any Borrower, the occurrence of any Event of Default or any other act, occurrence or event whatsoever, whether the same occurs, before, on or after the date on which an Equalization Payment is required to be made. All
Equalization Payments shall be made by 4:00 p.m. Washington, D.C. time on the date such payment is 

  

 57 

 
required, provided that notice of such Equalization Payment shall have been given to the party obligated to make such payment by 1:00 p.m. Washington, D.C.
time; otherwise such Equalization Payment shall be made on the next Business Day. 
  
 (b) Unless the Administrative Agent shall have been notified in writing by any Lender no later than the close of business on the Business
Day before the Business Day on which an advance requested by the Borrowers is to be made, that such Lender will not make its ratable share of such advance, the Administrative Agent may assume that such Lender will make its ratable share of the
advance, and in reliance upon such assumption the Administrative Agent may (but in no circumstances shall be required to) make available to the Borrowers a corresponding amount. If and to the extent that any Lender fails to make such payment to the
Administrative Agent when required, such Lender shall pay such amount on demand (or, if such Lender fails to pay such amount on demand, the Borrowers shall arrange for the repayment of such amount to the Administrative Agent), together with interest
for the Administrative Agent’s own account for each day from and including the date of the Administrative Agent’s payment, to and including the date of repayment to the Administrative Agent (before and after judgment). Interest (a) if paid
by such Lender (i) for each day from and including the date of the Administrative Agent’s payment to and including the second Business Day thereafter, shall accrue at the Federal Funds Rate for such day, and (ii) for each day thereafter, shall
accrue at the rate or rates per annum payable under the Notes; and (b) if paid by the Borrowers, shall accrue at the rate or rates per annum payable under the Notes. All payments to the Administrative Agent under this Section shall be made to the
Administrative Agent at its office set forth in the preamble of this Agreement (or as otherwise directed by the Administrative Agent), in dollars, in immediately available funds, without set-off, withholding, counterclaim or other deduction of any
nature. 
  
 (c) All borrowings under this
Agreement shall be incurred from the Lenders pro rata on the basis of their respective Percentages (except to the extent advanced (i) as a Swing Line Loan, or (ii) by the Administrative Agent on behalf of any Lender as provided in subsection (a) or
(b) above). It is understood that no Lender shall be responsible for any other Lender’s failure to meet its obligation to make advances hereunder, and that each Lender shall be obligated to make advances required to be made by it hereunder
regardless of the failure of any other Lender to make its advances hereunder. 
  
 (d) Each payment and prepayment received by the Administrative Agent for the account of the Lenders shall be distributed first to the Swing Line Lender for application to any Swing Line Outstandings, and then to each
Lender entitled to share in such payment, ratably in accordance with each Lender’s Percentage. Notwithstanding the provisions of Section 9.2(e) of this Agreement, any Lender who has failed to fund its Percentage of any advance under the Loan
shall not be entitled to share in any such payment(s) until such time as the funding deficiency caused thereby, together with interest thereon (as provided in subsection (b) above), has been paid to the Administrative Agent in accordance with the
terms and conditions of this Agreement. Payments from the Administrative Agent to the Lenders shall be made by wire transfer in accordance with written instructions provided to the Administrative Agent by the Lenders from time to time. Unless the
Administrative Agent shall have received notice from the Borrowers prior to the date on which any payment is due to the Lenders hereunder that the Borrowers will not make such payment in full, the Administrative Agent may assume that the Borrowers
have made such payment in full on such date and the Administrative Agent, in reliance upon such assumption, may cause to be distributed to each Lender on such due date an amount equal to the amount then due such Lender. If and to the extent the
Borrowers shall not have made such payment in full to the Administrative Agent, each Lender shall repay to the Administrative Agent upon its demand therefor such amount distributed to such Lender, together with interest thereon at the overnight
Federal Funds Rate for each day from the date such amount is distributed to such Lender until the date such Lender repays such amount to the Administrative Agent. 
  

 58 

 (e) If any Lender shall obtain any payment (whether voluntary, involuntary, through the
exercise of any right of setoff, or otherwise) in excess of such Lender’s Percentage of payments, such Lender shall forthwith purchase from the other Lender(s) such participations in the Loans made by them as shall be necessary to cause such
purchasing Lender to share the excess payment ratably with each of the other Lender(s); provided, however, if all or any portion of such excess payment is thereafter recovered from such purchasing Lender, such purchase from the other Lender(s) shall
be rescinded and each other Lender shall repay to the purchasing Lender the purchase price to the extent of such recovery, together with an amount equal to such Lender’s ratable share (according to the proportion of (1) the amount of such
Lender’s required repayment, to (2) the total amount so recovered from the purchasing Lender) of any interest or other amount paid or payable by the purchasing Lender in respect of the total amount recovered. Each Borrower agrees that any
Lender purchasing a participation from another Lender pursuant to this Section 10.13(e), to the fullest extent permitted by law, may exercise all of its rights of payment with respect to such participation as fully as if such Lender were the direct
creditor of the Borrowers in the amount of such participation. 
  
 10.14. Benefit of Article. The provisions of this Article 10 are solely for the benefit of the Agents and Lenders. Except as provided in Section 10.8(b) of this Agreement, no Borrower shall have any rights under any of
the provisions of this Article 10; it being understood that the provisions of this Article 10 are not in limitation of any right, power, duty, obligation or liability which the Agents would have to or against any Borrower. 
  
 ARTICLE 11 
 CERTAIN ADDITIONAL RIGHTS AND 
 OBLIGATIONS REGARDING THE COLLATERAL 
  
 11.1. Power of Attorney. Each Borrower hereby reaffirms
its irrevocable appointment of the Administrative Agent, as its agent and attorney-in-fact, with power of substitution, having full power and authority, in its own name, in the name of any Lender(s), in the name of any Borrower or otherwise (but at
the cost and expense of the Borrowers and without notice to any Borrower), but only after the occurrence of an Event of Default which remains uncured beyond any applicable notice and grace period, to (i) notify account debtors obligated on any of
the Receivables to make payments thereon directly to the lockbox referenced in Section 11.2 of this Agreement, and to take control of the cash and non-cash proceeds of any such Receivables; (ii) compromise, extend or renew any of the Collateral
constituting Receivables or deal with any of the Collateral as the Administrative Agent may deem advisable; (iii) release its interest in, make exchanges or substitutions for and/or surrender, all or any part of any Borrower’s interest in all
or any part of the Collateral; (iv) remove from any Borrower’s place(s) of business all books, records, ledger sheets, correspondence, invoices and documents relating to or evidencing any of the Collateral, or without cost or expense to the
Administrative Agent, make such use of any Borrower’s place(s) of business as may be reasonably necessary to administer, control and/or collect the Collateral; (v) repair, alter or supply goods, if any, necessary to fulfill in whole or in part
the purchase order of any Account Debtor; (vi) demand, collect receipt for and give renewals, extensions, discharges and releases of all or any part of the Collateral; (vii) institute and prosecute legal and equitable proceedings to enforce
collection of, or realize upon, all or any part of the Collateral; (viii) settle, renew, extend, compromise, compound, exchange or adjust claims with respect to all or any part of the Collateral or any legal proceedings brought with respect thereto;
and (ix) receive and open all mail addressed to any Borrower, and notify the Post Office authorities to change the address for the delivery of mail to any Borrower to such address as the Administrative Agent may designate; it being understood that
the rights granted to the Administrative Agent in this clause (ix), which are operative on the occurrence of an Event of Default, shall not in any way limit or impair the other rights provided to the Administrative Agent and/or Lenders in this
Agreement or any other Loan Document, including, without limitation, their rights 

  

 59 

 
with respect to the Collateral Account and the below-referenced lockbox. Furthermore, each Borrower hereby reaffirms its irrevocable appointment of the
Administrative Agent, as its agent and attorney-in-fact, with power of substitution, having full power and authority, in its own name, in the name of any Lender(s), in the name of any Borrower or otherwise (but at the cost and expense of the
Borrowers and without notice to any Borrower) and regardless of whether an Event of Default has occurred or any act, event or condition which with notice or the lapse of time, or both, would constitute an Event of Default has occurred, to (a) file
financing statements and continuation statements covering the Collateral and execute the same on behalf of any Borrower; (b) charge against any banking account of any Borrower any item of payment credited to any Borrower’s account which is
dishonored by the drawee or maker thereof; and/or (iii) endorse the name of any Borrower upon any items of payment relating to the Collateral or upon any proof of claim in bankruptcy against any Account Debtor. 
  
 11.2. Lockbox. Each Borrower hereby authorizes the
Administrative Agent to receive and collect any amount or amounts due or to become due on account of any Receivables and, at its discretion, to apply the same to the repayment of the Notes, and each Borrower agrees that, as of the date hereof, it
has established and shall continually maintain on terms and conditions satisfactory to the Administrative Agent in all respects, one or more lockboxes (and, if required by the Administrative Agent, one or more blocked accounts) for the collection of
Receivables. Except as otherwise may be approved by the Administrative Agent in writing, any checks or other remittances received by any Borrower in payment of the Receivables shall be held in trust by each Borrower for the Administrative Agent and
Lenders. Each Borrower represents, warrants, covenants and agrees that it has directed, or shall direct, within thirty (30) days of the date hereof, within thirty (30) days of such Borrower becoming a “Borrower” party to this Agreement and
the other Loan Documents (if applicable) or within such longer period as may be reasonably required by any Borrower, but in all events within ninety (90) days of the date hereof or the joinder date, as the case may be), direct all of its customers
(other than certain customers as may be approved by the Administrative Agent) to make payments directly to the Administrative Agent, and/or include on all of its invoices, a direction to its customer to make all payments directly to the
Administrative Agent, at:

 11.3. Other
Agreements. Except as may otherwise be expressly permitted by the terms of this Agreement, and without limiting any other restrictions or provisions of this Agreement, each Borrower will (i) on demand, subject to any confidentiality and
secrecy requirements imposed by any Government agency, make available in form reasonably acceptable to the Administrative Agent, shipping documents and delivery receipts evidencing the shipment of goods which gave rise to the sale or lease of
inventory or of an account, contract right or chattel paper, completion certificates or other proof of the satisfactory performance of services which gave rise to the sale or lease of inventory or of an account, contract right or chattel paper, and
each Borrower’s copy of any written contract or order from which a sale or lease of inventory, an account, contract right or chattel paper arose; and (ii) when requested, advise the Administrative Agent when an Account Debtor returns or refuses
to retain any goods, the sale or lease of which gave rise to an account, contract right or chattel paper, and of any delay in delivery or performance, or claims made in regard to any sale or lease of inventory, account, contract right or chattel

  

 60 

 
paper. Upon reasonable notice, all such records will be available for examination by authorized agents of the Administrative Agent. 
  
 It is expressly understood and agreed, however, that the Administrative Agent
shall not be required or obligated in any manner to make any inquiries as to the nature or sufficiency of any payment received by it or to present or file any claims or take any other action to collect or enforce a payment of any amounts which may
have been assigned to it or to which it or the Lenders may be entitled hereunder at any time or times. 
  
 ARTICLE 12 
 MISCELLANEOUS 
  
 12.1. Remedies Cumulative. Each right, power and remedy of the Agents or Lenders provided for in this
Agreement or in any other Loan Document or now or hereafter existing at law or in equity, by statute or otherwise, shall be cumulative and concurrent and shall be in addition to every other right, power or remedy provided for in this Agreement or in
any other Loan Document, or now or hereafter existing at law or in equity, by statute or otherwise, and the exercise or beginning of the exercise by the Agents of any one or more of such rights, powers or remedies shall not preclude the simultaneous
or later exercise by the Agents of any or all such other rights, powers or remedies. 
  
 12.2. Waiver. Time is of the essence of this Agreement. No failure or delay by the Administrative Agent to insist upon the strict performance of any term, condition, covenant or agreement set
forth in this Agreement or any other Loan Document, or to exercise any right, power or remedy consequent upon a breach thereof, shall constitute a waiver of such term, condition, covenant or agreement or of any such breach, or preclude the
Administrative Agent from exercising any such right, power or remedy at any later time or times. By accepting payment after the due date of any of the Obligations, neither the Lenders nor the Administrative Agent shall be deemed to have waived
either the right to require prompt payment when due of all other Obligations, or the right to declare a default for failure to make payment of any such other Obligations. 
  
 12.3. Notices. Notices to either party shall be in writing and shall be delivered personally, by
first-class mail, by nationally-recognized overnight delivery service, by facsimile and/or by e-mail, in each case addressed to the parties at the addresses set forth below or otherwise designated in writing:

 Any communication hereunder will be
deemed given and effective (i) when actually received, in the case of hand delivery or nationally recognized courier service, (ii) on the third (3rd) Business Day after being deposited in the United States mail and sent first class, postage prepaid,
(iii) on the next Business Day after being deposited with a courier for overnight delivery, (iv) when completely sent and received, as evidenced by a transmission report from the sender’s facsimile machine, in the case of a facsimile
transmission, or (v) when completely sent and received, as evidenced by a software electronic mail log of the sender, in the case of an e-mail transmission. 
  
 12.4. Entire Agreement. This Agreement and the other Loan Documents constitute the entire agreement of the parties with respect to
the Loan and shall continue in full force and effect for so long as any Borrower shall be indebted hereunder or under any Note, and thereafter until the Administrative Agent shall have actually received written notice of the termination hereof from
the Borrowers, all Letters of Credit shall have been cancelled or expired and all Obligations incurred or contracted before receipt of such notice shall have been fully paid. 
  
 12.5. Relationship of the Parties. This Agreement provides for the extension of financial accommodations by
each Lender, in its capacity as lender, to the Borrowers, in their capacity as borrowers, and for the payment of interest and repayment of the Obligations by the Borrowers. Certain provisions herein, such as those relating to compliance with the
financial covenants, delivery to the Administrative Agent and Lenders of financial statements, and compliance with other affirmative and negative covenants are for the benefit of the Administrative Agent and Lenders to protect the Lenders’
interests in assuring repayment of the Obligations. Nothing contained in this Agreement shall be construed as permitting or obligating the Lenders or Agents to act as a financial or business advisor or consultant to any Borrower, as permitting or
obligating the Lenders or Agents to control any Borrower or to conduct any Borrower’s operations, as creating any fiduciary obligation on the part of any Lender or Agent to any Borrower, or as creating any joint venture, agency or other
relationship between the parties other than as explicitly and specifically stated in this Agreement. Each Borrower acknowledges that it has had the opportunity to obtain the advice of experienced counsel of its own choosing in connection with the
negotiation and execution of this Agreement and to obtain the advice of such counsel with respect to all matters contained herein, including, without limitation, the provision in this Agreement for waiver of trial by jury. Each Borrower further
acknowledges that it is experienced with respect to 

  

 63 

 
financial and credit matters and has made its own independent decision to request the Obligations and execute and deliver this Agreement. 
  
 12.6. Waiver of Jury Trial. Each Borrower hereby (a) covenants
and agrees not to elect a trial by jury of any issue triable by a jury, and (b) waives any right to trial by jury fully to the extent that any such right shall now or hereafter exist. This waiver of right to trial by jury is separately given by each
Borrower, knowingly and voluntarily, and this waiver is intended to encompass individually each instance and each issue as to which the right to a jury trial would otherwise accrue. The Administrative Agent is hereby authorized and requested to
submit this Agreement to any court having jurisdiction over the subject matter and the parties hereto, so as to serve as conclusive evidence of each Borrower’s herein contained waiver of the right to jury trial. Further, each Borrower hereby
certifies that no representative or agent of the Agents or any Lender (including the Agents’ counsel) has represented, expressly or otherwise, to the undersigned that the Agents or Lenders will not seek to enforce this provision waiving the
right to a trial by jury. 
  
 12.7. Submission to
Jurisdiction; Service of Process; Venue. Any judicial proceeding brought against any Borrower with respect to this Agreement or any other Loan Document may be brought in any court of competent jurisdiction in the Commonwealth of
Virginia, and by execution and delivery of this Agreement, each Borrower accepts for itself and in connection with its properties, generally and unconditionally, the non-exclusive jurisdiction of the aforesaid court, and irrevocably agrees to be
bound by any judgment rendered by such court in connection with this Agreement. Each Borrower irrevocably designates and appoints CT Corporation, whose address is 5511 Staples Mill, Richmond, Virginia 23228, as its agent to receive on its behalf
service of all process in any such proceeding in any court in the Commonwealth of Virginia, such service being hereby acknowledged by each Borrower to be effective and binding on it in every respect. A copy of any such process so served shall be
mailed by registered or certified mail to the Borrower at the address to which notices are to be addressed in accordance with this Agreement, except that any failure to mail such copy shall not affect the validity of service of process. Each
Borrower shall at all times maintain an agent for service of process pursuant to this provision. If any Borrower fails to appoint such an agent, or if such agent refuses to accept service, such Borrower hereby agrees that service upon it by mail
shall constitute sufficient notice. Nothing herein shall affect the right to serve process in any other manner permitted by law or shall limit the right of the Administrative Agent or Lenders to bring proceedings against any Borrower in the courts
of any other jurisdiction. 
  
 12.8. Changes in Capital
Requirements/Costs. If any change in, or the introduction, adoption, effectiveness, interpretation, reinterpretation or phase-in of, any law or regulation, directive, guideline, decision or request (whether or not having the force of law) of
any court, central bank, regulator or other governmental authority affects or would affect the amount of capital required or expected to be maintained by the Administrative Agent or any Lender, or person controlling the Administrative Agent or any
Lender, and the Administrative Agent determines (in its sole and absolute discretion) that the rate of return on its, the Lender’s or such controlling person’s capital as a consequence of its commitments or the loans made by the
Administrative Agent or such Lender is reduced to a level below that which the Administrative Agent, such Lender or such controlling person could have achieved but for the occurrence of any such circumstance, then, in any such case upon notice from
time to time by the Administrative Agent to the Borrowers, the Borrowers shall immediately pay directly to the Administrative Agent, for its own account or for the account of such Lender (as the case may be), additional amounts sufficient to
compensate the Administrative Agent, such Lender or such controlling person for such reduction in rate of return or the interest rate on the Notes shall be increased to a rate which shall retain the Lenders’ original rate of return on the
Lenders’ capital. A statement of the Administrative Agent as to any such additional amount(s) or increased rates of interest (including calculations thereof in reasonable detail) shall, in the absence of manifest error, be conclusive and
binding 

  

 64 

 
on the Borrowers. In determining such amount(s) or increased rates of interest, the Administrative Agent may use any method of averaging and attribution that
it (in its sole and absolute discretion) shall deem applicable. 
  
 12.9. Captions. The paragraph headings of this Agreement are for convenience of reference only, and in no way define, limit or describe the scope of this Agreement or the intent of any provision hereof. 
  
 12.10. Modification and Waiver. Neither this Agreement
nor any term, condition, covenant or agreement hereof may be changed, waived, discharged or terminated orally, but that may be accomplished only by an instrument in writing signed by the party against whom enforcement of the change, waiver,
discharge or termination is sought. 
  
 12.11. Successors
and Assigns; Transferability. 
  
 (a) Whenever in
this Agreement any of the parities hereto is referred to, such reference shall be deemed to include the permitted successors and assigns of such party; and all covenants, promises and agreements by or on behalf of the Borrowers, the Administrative
Agent, or the Lenders that are contained in this Agreement shall bind and inure to the benefit of their respective successors and assigns. 
  
 (b) Each Lender may assign to one or more Eligible Assignees all or a portion of its interests, rights and obligations under this Agreement (including all
or a portion of its Percentages of the Revolving Facility Commitments and the Loans at the time owing to it); provided, however, that (i) except in the case of an assignment to a Lender or an Affiliate of a Lender, (x) the Borrowers and the
Administrative Agent must give their prior written consent to such assignment (which consent shall not be unreasonably withheld or delayed); provided, however, that the consent of the Borrowers shall not be required to any such assignment during the
continuance of any Event of Default, and (y) the amount of the Percentages of the Revolving Facility Commitment or Revolving Loan of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Acceptance with
respect to such assignment is delivered to the Administrative Agent) shall not be less than Five Million and No/100 Dollars ($5,000,000.00), if in respect of a Revolving Facility Commitment or a Revolving Loan (or, if less, the entire remaining
amount of such Lender’s applicable Percentage of the Revolving Facility Commitment) or such lesser amount as the Borrowers and the Administrative Agent may from time to time agree (such agreement to be conclusively evidenced by the execution of
the related Assignment and Acceptance by all the parties thereto), (ii) the parties to each such assignment shall execute and deliver to the Administrative Agent an Assignment and Acceptance, together (except in the case of any assignment to an
Affiliate) with a processing and recordation fee of $3,500 and (iii) the Eligible Assignee, if it shall not be a Lender, shall deliver to the Administrative Agent a completed Administrative Questionnaire. Upon acceptance and recording pursuant to
paragraph (e) below, from and after the effective date specified in the particular Assignment and Acceptance, (A) the assignee thereunder shall be a party hereto and, to the extent of the interest assigned by such Assignment and Acceptance, have the
rights and obligations of a Lender under this Agreement and (B) the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Acceptance, by released from its obligations under this Agreement (and, in the case
of an Assignment and Acceptance covering all or the remaining portion of an assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto but shall continue to be entitled to the benefits of any
indemnities hereof intended to survive this Agreement as well as to any Fees accrued for its account and not yet paid). 
  
 (c) By executing and delivering an Assignment and Acceptance, the assigning Lender thereunder and the assignee thereunder shall be deemed to confirm to
and agree with each other and the other parties hereto as follows: (i) such assigning Lender warrants that it is the legal and beneficial owner 

  

 65 

 
of the interest being assigned thereby free and clear of any adverse claim and that its Percentage of the Revolving Facility Commitment, and the outstanding
balances of its Revolving Loans, in each case without giving effect to assignments thereof which have not become effective, are as set forth in such Assignment and Acceptance, (ii) except as set forth in clause (i) above, such assigning Lender makes
no representation or warranty and assumes no responsibility with respect to any statements, warranties or representations made in or in connection with this Agreement, or the execution, legality, validity, enforceability, genuineness, sufficiency or
value of this Agreement, any other Loan Document or any other instrument or document furnished pursuant hereto, or the financial condition of any Borrower or the performance or observance by any Borrower of any of its obligations under this
Agreement, any other Loan Document or any other instrument or document furnished pursuant hereto; (iii) such assignee represents and warrants that it is legally authorized to enter into such Assignment and Acceptance; (iv) such assignee confirms
that it has received a copy of this Agreement, together with copies of the most recent financial statements delivered pursuant to Section 6.3 of this Agreement and such other documents and information as it has deemed appropriate to make its own
credit analysis and decision to enter into such Assignment and Acceptance; (v) such assignee will independently and without reliance upon the Administrative Agent, such assigning Lender or any other Lender and based on such documents and information
as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement; (vi) such assignee appoints and authorizes the Administrative Agent to take such action as agent on its behalf
and to exercise such powers under this Agreement as are delegated to the Administrative Agent by the terms hereof, together with such powers as are reasonably incidental thereto; and (vii) such assignee agrees that it will perform in accordance with
their terms all the obligations which by the terms of this Agreement are required to be performed by it as a Lender. 
  
 (d) The Administrative Agent, acting for this purpose as an agent of the Borrowers, shall maintain at one of its offices, a copy of each Assignment and
Acceptance delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Percentage of the Revolving Facility Commitment of, and principal amount of the Loans owing to, each Lender pursuant to the terms hereof
from time to time (the “Register”). The entries in the Register shall be conclusive and the Borrowers, the Administrative Agent and the Lenders may treat each person whose name is recorded in the Register pursuant to the terms hereof as a
Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrowers and any Lender, at any reasonable time and from time to time upon reasonable prior notice.

  
 (e) Upon its receipt of a duly completed Assignment and
Acceptance executed by an assigning Lender and an Eligible Assignee, an Administrative Questionnaire completed in respect of the assignee (unless the assigned shall already be a Lender hereunder), the processing and recordation feed referred to in
paragraph (b) above and, if required, the written consent of the Borrowers and the Administrative Agent to such assignment, the Administrative Agent shall (i) accept such Assignment and Acceptance and (ii) record the information contained therein in
the Register. No assignment shall be effective unless it has been recorded in the Register as provided in this paragraph (e). 
  
 (f) Each Lender may without the consent of the Borrowers or the Administrative Agent sell participations to one or more Eligible Assignees in all or a
portion of its rights and obligations under this Agreement (including all or a portion of its Percentage of the Revolving Facility Commitment and the Loans owing to it); provided, however, that (i) such Lender’s obligations under this Agreement
shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, (iii) the participating banks or other entities shall be entitled to the benefit of the cost protection
provisions contained in this Agreement and shall be bound by the confidentiality provisions contained in this Agreement to the same extent as if they were Lenders and (iv) the Borrowers, the Administrative Agent and the Lenders shall continue to
deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement, and such 

  

 66 

 
Lender shall retain the sole right to enforce the obligations of the Borrowers relating to the Loans and to approve any amendment, modification or waiver of
any provision of this Agreement (other than amendments, modifications or waivers decreasing any fees payable hereunder or the amount of principal of or the rate at which interest is payable on the Loans, extending any scheduled principal payment
date or date fixed for the payment of interest on the Loans, increasing or extending the Revolving Facility Commitments or releasing all or substantially all the Borrowers or the Collateral). All amounts payable by the Borrowers to any Lender
hereunder in respect of any Loan and the applicability of the cost protection provisions contained in this Agreement shall be determined as if such Lender had not sold or agreed to sell any participation in such Loan, and as if such Lender were
funding the participated portion of such Loan the same way that it is funding the portion of such Loan in which no participation has been sold. 
  
 (g) Any Lender or participant may, in connection with any assignment or participation or proposed assignment or participation pursuant to this Section,
disclose to the assignee or participant or proposed assignee or participant any information relating to the Borrowers furnished to such Lender by or on behalf of the Borrowers; provided that, prior to any such disclosure of information designated by
the Borrowers as confidential, each such assignee or participant or proposed assignee or participant shall execute and agreement whereby such assignee or participant shall agree (subject to customary exceptions) to preserve the confidentiality of
such confidential information on terms no less restrictive than those applicable to the Lenders pursuant to this Agreement and/or applicable law. 
  
 (h) Any Lender may at any time assign all or any portion of its rights under this Agreement to secure extensions of credit to such Lender or in support of
obligations owed by Lender; provided that no such assignment shall release a Lender from any of its obligations hereunder or substitute any such assignee for such Lender as a party hereto. 
  
 (i) Notwithstanding anything to the contrary contained herein, any Lender (a
“Granting Lender”) may grant to a special purpose funding vehicle (an “SPC”), identified as such in writing from time to time by the Granting Lender to the Administrative Agent and the Borrowers, the option to provide to the
Borrowers all or any part of any Loan that such Granting Lender would otherwise be obligated to make to the Borrowers pursuant to this Agreement; provided that (i) nothing herein shall constitute a commitment by any SPC to make any Loan and (ii) if
an SPC elects not to exercise such option or otherwise fails to provide all or any part of such Loan, the Granting Lender shall be obligated to make such Loan pursuant to the terms hereof. The making of a Loan by an SPC hereunder shall utilize the
Percentage of the Revolving Facility Commitment of the Granting Lender to the same extent, and as if, such Loan were made by such Granting Lender. Each party hereto hereby agrees that no SPC shall be liable for any indemnity or similar payment
obligation under this Agreement (all liability for which shall remain with the Granting Lender). In furtherance of the foregoing, each party hereto hereby agrees (which agreement shall survive the termination of this Agreement) that, prior to the
date that is one year and one day after the payment in full of all outstanding commercial paper or other senior indebtedness of any SPC, it will not institute against, or join any other person in instituting against, such SPC any bankruptcy,
reorganization, arrangement, insolvency or liquidation proceedings under the laws of the United States or any State thereof. In addition, notwithstanding anything to the contrary contained in this Section, any SPC may (i) with notice to, but without
the prior written consent of, the Borrowers and the Administrative Agent and without paying any processing fee therefore, assign all or a portion of its interests in any Loans to the Granting Lender or to any Eligible Assignee (consented to by the
Borrowers and Administrative Agent) providing liquidity and/or credit support to or for the account of such SPC to support the funding or maintenance of Loans, and (ii) disclose on a confidential basis any non-public information relating to its
Loans to any rating agency, commercial paper dealer or provider of any surety, guarantee or credit or liquidity enhancement to such SPC. 
  

 67 

 (j) The Borrowers shall not assign or delegate any of their rights or duties hereunder without the prior
written consent of the Administrative Agent and each Lender, and any attempted assignment without such consent shall be null and void. 
  
 (k) In the event that S&P, Moody’s, and Thompson’s BankWatch (or InsuranceWatch Ratings Service, in the case of Lenders that are insurance
companies (or Best’s Insurance Reports, if such insurance company is not rated by Insurance Watch Ratings Service) shall, after the date that any Lender becomes a Lender, downgrade the long-term certificate deposit ratings of such Lender, and
the resulting ratings shall be below (I) with respect to any Lender party to this Agreement as of the Restatement Date, such Lender’s rating as of the Restatement Date, and (II) with respect to any other Lender, BBB-, Baa3 and C (or BB, in the
case of a Lender that is an insurance company (or B, in the case of an insurance company not rated by InsuranceWatch Ratings Service)), then the Administrative Agent shall have the right, but not the obligation at its own expense, upon notice to
such Lender to replace (or to request the Borrowers to use their reasonable efforts to replace) such Lender with an Eligible Assignee (in accordance with and subject to the restrictions contained in paragraph (b) above), and such Lender hereby
agrees to transfer and assign without recourse (in accordance with and subject to the restrictions contained in paragraph (b) above) all its interests, rights and obligations in respect of its Percentage of the Revolving Facility Commitment to such
Eligible Assignee; provided, however, that (i) no such assignment shall conflict with any law, rule and regulation or order of any Governmental and (ii) such Eligible Assignee, as the case may be, shall pay to such Lender in immediately available
funds on the date of such assignment the principal of and interest accrued to the date of payment on the Loans made by such Lender hereunder and all other amounts accrued for such Lender’s account or owed to it hereunder. 
  
 12.12. Governing Law; Binding Effect. This Agreement
shall be governed by and construed in accordance with the laws of the Commonwealth of Virginia (without regard to conflicts of laws provisions), and shall be binding upon each Borrower and inure to the benefit of the parties hereto and their
respective successors and assigns. 
  
 12.13. Gender;
Number. As used herein, the singular number shall include the plural, the plural the singular and the use of the masculine, feminine or neuter gender shall include all genders, as the context may require. 
  
 12.14. Joint and Several Liability. Each Borrower shall
be jointly and severally liable for the payment and performance of all obligations and liabilities hereunder. 
  
 12.15. Materiality. Unless the context clearly indicates to the contrary, determinations regarding the materiality of any act, event,
condition or circumstance shall be in the reasonable judgment of the Administrative Agent. 
  
 12.16. Reliance on the Administrative Agent. Each Borrower shall be entitled to assume that any and all consents, approvals or notices issued or granted by the Administrative Agent pursuant to the terms
and provisions of this Agreement were, to the extent necessary, authorized by the Required Lenders or all of the Lenders, as applicable. 
  
 12.17. The Patriot Act. Each Lender and the Administrative Agent (for itself and not on behalf of any Lender) hereby notifies the Borrowers
that pursuant to the requirements of the Patriot Act, it is required to obtain, verify and record information that identifies the Borrowers, which information includes the name and address of the Borrowers and other information that will allow such
Lender or the Administrative Agent, as applicable, to identify the Borrowers in accordance with the Act. 
  
 12.18. Taxes. All payments by the Borrowers of principal of, and interest on, Revolving Loans and all other amounts payable pursuant to any
Loan Document shall be made free and clear of and 

  

 68 

 
without deduction for any present or future income, excise, stamp or franchise taxes and other taxes, fees, duties, withholdings or other charges of any
nature whatsoever imposed by any taxing authority, but excluding franchise taxes and taxes imposed on or measured by the Administrative Agent’s and/or any Lender’s net income or receipts (such non-excluded items being called
“Taxes”). In the event that any withholding or deduction from any payment to be made by the Borrowers hereunder is required in respect of any Taxes pursuant to any applicable law, rule or regulation, then the Borrowers will: 
  
 (a) pay directly to the relevant authority the full amount
required to be so withheld or deducted; 
  
 (b)
promptly forward to the Administrative Agent an official receipt or other documentation satisfactory to the Administrative Agent evidencing such payment to such authority; and 
  
 (c) pay to the Administrative Agent, for its own account or for the account of such Lender (as the case may
be), such additional amount or amounts as is necessary to ensure that the net amount actually received by the Administrative Agent, for its own account or for the account of such Lender (as the case may be), will equal the full amount the
Administrative Agent or such Lender (as applicable) would have received had no such withholding or deduction been required. 
  
 Moreover, if any Taxes are directly asserted against the Administrative Agent or any Lender with respect to any payment received by the Administrative Agent or any Lender
hereunder, the Administrative Agent or such Lender may pay such Taxes and the Borrowers will promptly pay such additional amount (including any penalties, interest or expenses) as is necessary in order that the net amount received by the
Administrative Agent or such Lender (as the case may be) after the payment of such Taxes (including any Taxes on such additional amount) shall equal the amount the Administrative Agent or such Lender (as the case may be) would have received had not
such Taxes been asserted. 
  
 If the Borrowers fail to pay any Taxes when due to
the appropriate taxing authority or fail to remit to the Administrative Agent the required receipts or other required documentary evidence, the Borrowers shall indemnify the Administrative Agent and the Lenders for any incremental Taxes, interest or
penalties that may become payable by the Administrative Agent or any Lender as a result of any such failure. 
  
 12.19. Counterparts. This Agreement may be executed by facsimile and/or in any number of counterparts, all of which together shall
constitute one and the same document. Each party agrees to be bound by its facsimile signature.
