                           FIRST NATIONAL BANK & TRUST
                              EMPLOYMENT AGREEMENT
                                RICHARD T. NELSON

     THIS EMPLOYMENT AGREEMENT (this "Agreement"), signed as of February 6,
2009, between FIRST COMPANY, FIRST NATIONAL BANK & TRUST (the "Bank") and
Richard T. Nelson ("Executive") and ratified by GLACIER BANCORP, INC. ("GBCI"),
takes effect on the effective date of the pending Merger (the "Effective Date")
referenced below.

                                    RECITALS

A.   First Company and the Bank have entered into a Plan and Agreement Merger
     (the "Merger Agreement") with GBCI, pursuant to which First Company will
     merge with and into GBCI, and the Bank will become a wholly owned
     subsidiary of GBCI (the "Merger").

B.   Executive presently serves as President of the First Company and will
     continue to do so until the Effective Date.

C.   GBCI and the Bank desire Executive to be employed by the Bank from and
     after the Effective Date, under the terms and conditions of this Agreement,
     and Executive desires to be employed by the Bank from and after the
     Effective Date, under the terms and conditions of this Agreement.

                                    AGREEMENT

     In consideration of the promises set forth in this Agreement, the parties

     accepts employment by the Bank on the terms and conditions set forth in
     this Agreement. Executive's title will be President and Chief Executive
     Officer of the Bank.

     a.   Term. The term of this Agreement ("Term") is three years, beginning on

          the Merger Agreement is terminated for any reason.

                                       1

3.   DUTIES. The Bank will employ Executive as its President and Chief Executive
     Officer. Executive will faithfully and diligently perform the duties
     assigned to him, which duties will be consistent with his title and
     position. Executive will report directly to GBCI's President and Chief
     Executive Officer. The Bank's or GBCI's board of directors may, from time
     to time, modify Executive's performance responsibilities to accommodate
     management objectives of the Bank or of GBCI. Executive will assume any
     additional positions, duties, and responsibilities as may reasonably be
     requested of him with or without additional compensation, as appropriate
     and consistent with his title and position.

4.   EXTENT OF SERVICES. Executive will devote all of his working time,
     attention and skill to the duties and responsibilities referenced in
     Section 3. To the extent that such activities do not interfere with his
     duties under Section 3, Executive may participate in other businesses as a
     passive investor, but (a) Executive may not actively participate in the
     operation or management of those businesses, and (b) Executive may not,
     without the Bank's prior written consent, make or maintain any investment
     in a business with which the Bank and/or GBCI has an existing competitive
     or commercial relationship.

5.   SALARY. Executive will receive an annualized salary of $144,051.
     Executive's salary will be paid in accordance with the Bank's regular
     payroll schedule. Subsequent salary increases are subject to the Bank's
     annual review of Executive's compensation and performance.

6.   INCENTIVE COMPENSATION. Until such time as Executive becomes eligible to
     participate in GBCI's short term incentive plan and long term incentive
     plan for bank presidents, Executive's bonuses, if any, will be determined
     by the Bank's board of directors in conjunction with GBCI's President and
     CEO. In making bonus determinations, factors such as Executive's
     performance of his duties and the safety, soundness and profitability of
     the Bank will be considered. Executive's bonus will reflect Executive's
     contribution to the performance of the Bank during the year.

7.   VACATION AND BENEFITS.

     a.   Vacation and Holidays. Executive will receive four weeks of paid
          vacation each year. Executive's ability to carry over or accumulate
          vacation will be governed by the Bank's and/or GBCI's applicable
          policies.

     b.   Benefits. Executive will be entitled to participate in any group life
          insurance, disability, health and accident insurance plans, profit
          sharing plan and in other employee fringe benefit programs the Bank or
          GBCI may have in effect from time to time for its similarly situated
          employees, in accordance with and subject to any policies adopted by
          the Bank's or GBCI's board of directors with respect to the plans or
          programs, including without limitation, any incentive or employee
          stock option plan, deferred compensation plan and 401(k) plan. Neither
          the Bank nor GBCI through this Agreement obligates itself to make any
          particular benefits available to its employees.

                                       2

     c.   Business Expenses. The Bank will reimburse Executive for ordinary and
          necessary expenses which are consistent with past practice at the Bank
          (including, without limitation, travel, entertainment, and similar
          expenses) and which are incurred in performing and promoting the
          Bank's business. Executive will present from time to time itemized
          accounts of these expenses, subject to any limits of Bank policy or
          the rules and regulations of the Internal Revenue Service.

     c.   Bank Automobile. Executive will have exclusive use of a Bank
          automobile and shall maintain appropriate records with respect to such
          use for tax purposes.

8.   TERMINATION OF EMPLOYMENT.

     a.   Termination By Bank for Cause. If the Bank terminates Executive's
          employment for Cause (defined below) or Executive terminates his
          employment without Good Reason (defined below) before this Agreement
          terminates, the Bank will pay Executive the salary earned and expenses
          reimbursable under this Agreement incurred through the date of his
          termination. Executive will have no right to receive compensation or
          other benefits for any period after termination under this Section
          8(a).

     b.   Other Termination By Bank. If the Bank terminates Executive's
          employment without Cause before this Agreement terminates, or
          Executive terminates his employment for Good Reason, then contingent
          upon Executive's execution of a release of any and all claims arising
          out of such termination or his employment, the Bank will pay Executive
          a lump sum payment equal to one times Executive's annual base salary
          at the time of termination.

     c.   Death or Disability. This Agreement terminates (1) if Executive dies
          or (2) if Executive is unable to perform his duties and obligations
          under this Agreement for a period of 90 consecutive days as a result
          of a physical or mental disability arising at any time during the term
          of this Agreement, unless with reasonable accommodation Executive
          could continue to perform his duties under this Agreement and making
          these accommodations would not pose an undue hardship on the Bank. If
          termination occurs under this Section 8(c), Executive or his estate
          will be entitled to receive all compensation and benefits earned and
          expenses reimbursable through the date Executive's employment
          terminated.

     d.   Return of Bank Property. If and when Executive ceases, for any reason,
          to be employed by the Bank, Executive must return to the Bank all
          keys, pass cards, identification cards and any other property of the
          Bank or GBCI. At the same time, Executive also must return to the Bank
          all originals and copies (whether in hard copy, electronic or other
          form) of any documents, drawings, notes, memoranda, designs, devices,
          diskettes, tapes, manuals, and specifications which constitute
          proprietary information or material of the Bank or GBCI. The
          obligations in this paragraph include the return of documents and
          other materials that may be in his desk at work, in his car, in place
          of residence, or in any other location under his control.

     e.   Cause. "Cause" means any one or more of the following:

          (1)  Willful misfeasance or gross negligence in the performance of
               Executive's duties;

          (2)  Conviction of a crime in connection with his duties; or

          (3)  Conduct demonstrably and significantly harmful to the Bank, as
               reasonably determined on the advice of legal counsel by the
               Bank's board of directors.

     f.   Good Reason. "Good Reason" means only any one or more of the
          following:

          (1)  Reduction of Executive's salary or reduction or elimination of
               any compensation or benefit plan benefiting Executive, unless the
               reduction or elimination is generally applicable to substantially
               all Bank employees (or employees of a successor or controlling
               entity of the Bank) formerly benefited;

          (2)  The assignment to Executive without his consent of any authority
               or duties materially inconsistent with Executive's position as of
               the date of this Agreement;

          (3)  A relocation or transfer of Executive's principal place of
               employment that would require Executive to commute on a regular
               basis more than sixty (60) miles each way from the Bank's present
               main office location.

9.   CONFIDENTIALITY. Executive will not, after the date this Agreement was
     signed, including during and after its Term, use for his own purposes or
     disclose to any other person or entity any confidential business
     information concerning First Company, the Bank or GBCI or their business
     operations, unless (1) the Bank or GBCI consents to the use or disclosure
     of their respective confidential information; (2) the use or disclosure is
     consistent with Executive's duties under this Agreement; (3) disclosure is
     required by law or court order; or (4) the information is made or otherwise
     becomes public. For purposes of this Agreement, confidential business
     information includes, without limitation, various confidential information
     concerning all aspects of current and future operations, nonpublic
     information on investment management practices, marketing plans, pricing
     structure and technology of either the Bank or GBCI. Executive will also
     treat the terms of this Agreement as confidential business information.

10.  RESTRICTIVE COVENANTS.

     a.   Competitive Activities. During the period of his employment and for
          one year after Executive's employment with the Bank has ended,
          Executive will not, directly or indirectly, as a founder, shareholder,
          director, officer, employee, partner, agent, consultant, lessor,
          creditor or otherwise, provide management, supervisory or other
          similar services to any person or entity engaged in any

                                       4

<PAGE>

          business within Park County, Wyoming or Big Horn County, Wyoming, that
          is competitive with the business of the Bank or GBCI as conducted
          during the term of this Agreement or as conducted as of the date of
          termination of employment, including any preliminary steps associated
          with the formation of a new financial institution.

     b.   Non-Interference. During the period of his employment and for one year
          after Executive's employment with the Bank has ended, Executive will
          not, directly or indirectly, persuade or entice, or attempt to
          persuade or entice, (i) any employee of the Bank or GBCI to terminate
          his/her employment with the Bank or GBCI, or (ii) any person or entity
          to terminate, cancel, rescind or revoke its business or contractual
          relationships with the Bank or GBCI.

11.  ENFORCEMENT.

     a.   The Bank and Executive stipulate that, in light of all of the facts
          and circumstances of the relationship between Executive and the Bank,
          the agreements referred to in Sections 9 and 10 (including without
          limitation their scope, duration and geographic extent) are fair and
          reasonably necessary for the protection of the Bank's and GBCI's
          confidential information, goodwill and other protectable interests. If
          a court of competent jurisdiction should decline to enforce any of
          those covenants and agreements, Executive and the Bank request the
          court to reform these provisions to restrict Executive's use of
          confidential information and Executive's ability to compete with the
          Bank and GBCI to the maximum extent, in time, scope of activities, and
          geography, the court finds enforceable.

     b.   Executive acknowledges the Bank and GBCI will suffer immediate and
          irreparable harm that will not be compensable by damages alone if
          Executive repudiates or breaches any of the provisions of Sections 9
          or 10 or threatens or attempts to do so. For this reason, under these
          circumstances, the Bank, in addition to and without limitation of any
          other rights, remedies or damages available to it at law or in equity,
          will be entitled to obtain temporary, preliminary and permanent
          injunctions in order to prevent or restrain the breach, and the Bank
          will not be required to post a bond as a condition for the granting of
          this relief.

12.  COVENANTS. Executive specifically acknowledges the receipt of adequate
     consideration for the covenants contained in Sections 9 and 10 and that the
     Bank is entitled to require him to comply with these Sections. These
     Sections will survive termination of this Agreement. Executive represents
     that if his employment is terminated, whether voluntarily or involuntarily,
     Executive has experience and capabilities sufficient to enable Executive to
     obtain employment in areas which do not violate this Agreement and that the
     Bank's enforcement of a remedy by way of injunction will not prevent
     Executive from earning a livelihood.

                                       5

13.  ARBITRATION.

     a.   Arbitration. At either party's request, the parties must submit any
          dispute, controversy or claim arising out of or in connection with, or
          relating to, this Agreement or any breach or alleged breach of this
          Agreement, to arbitration under the American Arbitration Association's
          rules then in effect (or under any other form of arbitration mutually
          acceptable to the parties). A single arbitrator agreed on by the
          parties will conduct the arbitration. If the parties cannot agree on a
          single arbitrator, each party must select one arbitrator and those two
          arbitrators will select a third arbitrator. This third arbitrator will
          hear the dispute. The arbitrator's decision is final (except as
          otherwise specifically provided by law) and binds the parties, and
          either party may request any court having jurisdiction to enter a
          judgment and to enforce the arbitrator's decision. The arbitrator will
          provide the parties with a written decision naming the substantially
          prevailing party in the action. This prevailing party is entitled to
          reimbursement from the other party for its costs and expenses,
          including reasonable attorneys' fees.

     b.   Governing Law. All proceedings will be held at a place designated by
          the arbitrator in Yellowstone County, Montana. The arbitrator, in
          rendering a decision as to any state law claims, will apply Wyoming
          law.

     c.   Exception to Arbitration. Notwithstanding the above, if Executive
          violates Section 9 or 10, the Bank will have the right to initiate the
          court proceedings described in Section 11(b), in lieu of an
          arbitration proceeding under this Section 13.

14.  MISCELLANEOUS PROVISIONS.

     a.   Entire Agreement. This Agreement constitutes the entire understanding
          and agreement between the parties concerning its subject matter and
          supersedes all prior agreements, correspondence, representations, or
          understandings between the parties relating to its subject matter.

     b.   Binding Effect. This Agreement will bind and inure to the benefit of
          the Bank's, GBCI's and Executive's heirs, legal representatives,
          successors and assigns.

     c.   Litigation Expenses. If either party successfully seeks to enforce any
          provision of this Agreement or to collect any amount claimed to be due
          under it, this party will be entitled to reimbursement from the other
          party for any and all of its out-of-pocket expenses and costs
          including, without limitation, reasonable attorneys' fees and costs
          incurred in connection with the enforcement or collection.

     d.   Waiver. Any waiver by a party of its rights under this Agreement must
          be written and signed by the party waiving its rights. A party's
          waiver of the other party's breach of any provision of this Agreement
          will not operate as a waiver of any other breach by the breaching
          party.

                                       6

<PAGE>

     e.   Assignment. The services to be rendered by Executive under this
          Agreement are unique and personal. Accordingly, Executive may not
          assign any of his rights or duties under this Agreement.

     f.   Amendment. This Agreement may be modified only through a written
          instrument signed by both parties.

     g.   Severability. The provisions of this Agreement are severable. The
          invalidity of any provision will not affect the validity of other
          provisions of this Agreement.

     h.   Governing Law and Venue. This Agreement will be governed by and
          construed in accordance with Wyoming law, except to the extent that
          certain regulatory matters may be governed by federal law. The parties
          must bring any legal proceeding arising out of this Agreement in
          Yellowstone County, Montana.

     i.   Counterparts. This Agreement may be executed in one or more
          counterparts, each of which will be deemed an original, but all of
          which taken together will constitute one and the same document.

     j.   Counsel Review. Executive acknowledges that he has had the opportunity
          to consult with independent counsel with respect to the negotiation,
          preparation, and execution of this Agreement.

     k.   IRC Section 409A. The provisions of this Agreement are intended to
          comply with Section 409A of the U.S. Internal Code of 1986, as
          amended, U.S. Treasury regulations issued thereunder, and related U.S.
          Internal Revenue Service guidance ("409A Rules"). Such provisions will
          be interpreted and applied in a manner consistent with the 409A Rules
          so that payments and benefits provided to Executive hereunder will
          not, to the greatest extent possible, be subject to taxation under
          such Section 409A. Notwithstanding any contrary provisions hereof,
          this Agreement may be amended if and to the extent GBCI and/or the
          Bank determines that such amendment is necessary to comply with the
          409A Rules.

CONTRIBUTIONS, PAYMENTS AND CLOSING

     Section 2.1 Pre-Closing Matters.

          (a) Pre-Closing Expenditures and Working Capital.

          (i) At least three Business Days before the proposed Closing Date, Regency HIG shall
provide the Investors with its good faith estimate of the Pre-Closing Expenditures (the
“Estimated Pre-Closing Expenditures”) together with any supporting information reasonably
requested by the Investors. At least three Business Days before the proposed Closing Date,
Regency HIG shall provide the Investors its good faith estimate of Working Capital as of the
Closing Date (the “Estimated Working Capital”), together with any supporting information
reasonably requested by the Investors. Attached as Schedule 2.1(a) is an agreed
upon template that includes the methodology that shall be used by Regency HIG in preparing
Estimated Working Capital and Working Capital.

          (ii) As soon as practicable, but in no event later than 90 days after the Closing Date,
Regency HIG shall update and provide to the Investors its calculation of (A) the Pre-Closing
Expenditures and (B) Working Capital as of the Closing Date based on the methodologies set
forth in Schedule 2.1(a).

          (iii) Regency HIG and the Investors shall have full access to documents and information
to the extent reasonably necessary to prepare and evaluate the calculation of the Adjustment
Items. Any Investor may dispute Regency HIG’s calculation of the Adjustment Items by
delivering to Regency HIG and the other Investors, within 20 Business Days of its receipt of
the calculation, a written notice (a “Dispute Notice”), which shall specify the elements of
the calculation of the Adjustment Items that such Investor disputes. Any elements of
Regency HIG’s calculations of the Adjustment Items not so specified as challenged or
disputed in the Dispute Notice shall be deemed accepted by all Parties and shall not be
subject to subsequent challenge by any Party for any purpose.

          (iv) If any Investor timely delivers a Dispute Notice, Regency HIG and the Investors
will seek to resolve the dispute by negotiations among such Parties. Any such resolution
(including any resolution of less than all the items disputed in the Dispute Notice) shall
be binding upon all the Parties. If, however, within 20 days following the delivery of a
Dispute Notice, Regency HIG and the Investors have not fully resolved the Dispute Notice
(each a “Remaining Dispute”), then either Regency HIG or any Investor may initiate binding
arbitration of the Remaining Disputes by giving written notice of an intent to arbitrate to
the other Parties. The arbitrator for such Remaining Disputes shall be a partner in a
nationally recognized firm of independent public accountants mutually acceptable to Regency
HIG and the Investors; if, however, Regency HIG and the GE Investor and the Alinda Investors
have not agreed on the selection of the arbitrator within ten days following the delivery
of a notice of intent to arbitrate, then each such Party shall select (and notify in writing
the other Party of such selection) as a “Selector” a

3

 

partner at a nationally recognized firm of independent public accountants, and these
two Selectors shall select, within ten days of delivery of the last such notice of
selection, a partner in a nationally recognized firm of independent public accountants who
shall serve as the arbitrator to resolve the Remaining Disputes. The Parties will cooperate
with this arbitrator and timely provide him or her with all information as such arbitrator
shall request. The arbitrator shall be directed to resolve the Remaining Disputes as
promptly as practicable and to provide the Parties with a written decision regarding his or
her decision on each Remaining Dispute, but in no case later than 30 days after the
arbitrator has been selected. The decision by the arbitrator selected pursuant to this
Section 2.1(a)(iv) with respect to each Remaining Dispute shall be binding on all
Parties for all purposes.

          (v) Promptly, but in all events within three Business Days following the agreement or
resolution pursuant to this Section 2.1 of all disputes regarding the calculations
of the Adjustment Items, (A) if the Regency Closing Payment shall be greater than the Total
Adjustment Items, Regency HIG shall pay the Company cash in an amount equal to the positive
difference between the Regency Closing Payment and the Total Adjustment Items; and (B) if
the Total Adjustment Items shall be greater than the Regency Closing Payment, the Company
shall pay Regency HIG cash in an amount equal to the positive difference between the Total
Adjustment Items and the Regency Closing Payment. For avoidance of doubt, any amounts due
from any Party pursuant to this Section 2.1(a)(v) shall not be subject to the
provisions of Article 5.

          (b) Pre-Closing Cash Balances. For the avoidance of doubt, (i) the Parties
acknowledge and agree that all cash balances of RIGS and the Company immediately prior to the
Closing shall be the property of Regency HIG and (ii) notwithstanding any other provisions of this
Agreement to the contrary (including Section 6.7), Regency HIG shall be entitled to cause
RIGS and the Company to distribute all cash balances of RIGS and the Company to Regency HIG prior
to the Closing.

     Section 2.2 Contributions and Payments. Subject to the terms and conditions of this
Agreement, at the Closing, the following contributions, unit issuances and payments shall be made:

          (a) Each Investor shall contribute to the Company in immediately available funds, to an
account designated by the Company to the Investors (which account shall be so designated no later
than two Business Days prior to the Closing), the amount set forth opposite such Investor’s name in
the column entitled “Cash Investment Amount” on Exhibit F in exchange for the number of GP
Units set forth opposite such Investor’s name in the column entitled “GP Units” on Exhibit
F. In its capacity as a holder of such GP Units and as a Partner, each Investor shall have the
obligations set forth in the Company Partnership Agreement with respect to the contribution of
additional capital to the Company, but shall have no other obligation to contribute any additional
capital to the Company, except as otherwise expressly provided in the Company Partnership
Agreement.

          (b) Regency HIG shall contribute to the Company, pursuant to the RIGS Assignment and
Assumption Agreement, all of the RIGS Interests in exchange for the GP Units

4

 

set forth opposite Regency HIG’s name in the column entitled “GP Units” on Exhibit F.
In its capacity as a holder of such GP Units and as a Partner, Regency HIG shall have no obligation
to contribute any additional capital to the Company, except as otherwise expressly provided in the
Company Partnership Agreement.

          (c) The Company shall distribute to Regency HIG in immediately available funds, to an account
designated by Regency HIG to the Company (which account shall be so designated no later than two
Business Days prior to the Closing), an amount equal to the Regency Closing Payment. To avoid
characterization of such distribution as a sale of a portion of the Assets to the Company, Regency
HIG shall provide the Management Committee with information reasonably requested by the Management
Committee to avoid treating such distribution as part of a sale under Code Section 707.

     Section 2.3 Closing. Subject to the terms and conditions of this Agreement, the closing of
the transactions contemplated by this Agreement (the “Closing”) shall take place at the offices of
Vinson & Elkins LLP, First City Tower, 1001 Fannin Street, Suite 2500, Houston, Texas 77002 on

satisfied (other than those conditions that by their nature are to be satisfied at the Closing, but

earlier than the first Business Day that is 11 Business Days after the date on which the conditions
precedent set forth in Section 7.1(c), Section 7.2(d) and Section 7.2(e)
have been satisfied, or if permissible, waived, and Regency HIG has notified the Alinda Investors
that all other conditions to Closing set forth in Article 7 that are not within the control
of the Alinda Investors will be satisfied without undue delay, or (b) at such other place, time and
date as is agreed to in writing by the Parties (the “Closing Date”). The Closing will be deemed

to do business as a foreign partnership, limited partnership or limited liability company, as the
case may be, in each jurisdiction in which the property currently owned, leased or operated by it
or the nature of the business currently conducted by it makes such qualification necessary.

7

 

     Section 3.2 Authority; Enforceability.

          (a) Each Regency Entity has the requisite general partnership, limited partnership or limited
liability company power and authority, as applicable, to execute and deliver the Transaction

the part of such Regency Entity is necessary to authorize the Transaction Documents or to
consummate the Transactions.

          (b) Each of the Transaction Documents to which any Regency Entity is, or will be as of the
Closing, a party has been (or will be, in the case of Transaction Documents to be delivered at the
Closing) duly executed and delivered by such Regency Entity and, assuming the due authorization,
execution and delivery by the other parties thereto, each Transaction Document constitutes (or will
constitute, in the case of Transaction Documents to be delivered at the Closing) the valid and
binding agreement of such Regency Entity, and is (or will be, in the case of Transaction Documents
to be delivered at the Closing) enforceable against such Regency Entity in accordance with its
terms, except as such enforceability may be limited by applicable bankruptcy, insolvency,
fraudulent transfer, reorganization, moratorium and similar Laws relating to or affecting
creditors’ rights generally and by general principles of equity (regardless of whether such
enforceability is considered in a proceeding in equity or at law).

     Section 3.3 No Violation; Consents and Approvals. Except as set forth on Schedule
3.3:

          (a) The execution, delivery and performance of the Transaction Documents by any Regency Entity

real property interests grant to RIGS the right to construct, operate and maintain the pipeline
contemplated on the Execution Date by the Haynesville Expansion Project in, over, under and across
the property covered by such real property interests, except as would not (i) materially impair or
delay the development and construction of the pipeline as contemplated on the Execution Date as a
whole or any individual material segment thereof or (ii) materially increase the cost to develop,
construct, operate or maintain the pipeline as contemplated on the Execution Date in excess of the
costs thereof set forth in the Haynesville Expansion Budget or the Initial Operating Budget. To
the Knowledge of Regency HIG, there are no impediments to obtaining the real property interests not
currently held by RIGS that are necessary to complete the Haynesville Expansion Project in the
ordinary course without material delay, condition or expense, other than as set forth in the

required to construct and complete the Haynesville Expansion Project that are not in existence on
the Execution Date, including the Firm Transportation Contracts, (all of which, together with the
Existing Haynesville Expansion Contracts, are collectively referred to as the “Haynesville
Expansion Contracts”). Except as set forth on Part F of Schedule 3.21, any Haynesville
Expansion Contract that is required to enable RIGS to construct and complete the Haynesville
Expansion Project that is not obtained by the Execution Date can be obtained in the ordinary course
without material delay, condition or expense, other than as set forth in the Haynesville Expansion
Budget. Regency HIG has provided or made available to the Investors complete and correct copies of
all Existing Haynesville Expansion Contracts. Except as set forth on Part G of Schedule
3.21, each Existing Haynesville Expansion Contract is a legal, valid and binding obligation of
RIGS, and, to the Knowledge of Regency HIG, of each other party thereto in accordance with its
respective terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization,
moratorium and similar Laws relating to or affecting creditors’ rights generally or by principles
of equity (regardless of whether such enforceability is considered in a proceeding in equity or at
law). Except as set forth on Part G of Schedule 3.21, neither RIGS nor, to the Knowledge
of Regency HIG, any other party to any Existing Haynesville Expansion Contract, is (with or without
the lapse of time or the giving of notice, or both) in breach or default thereunder, nor has any
Regency Entity received written notice that Regency HIG is in breach or default thereunder. Except
as set forth on Part G of Schedule 3.21, no Regency Entity has received a notice exercising
a right to terminate an Existing Haynesville Expansion Contract.

          (g) To the Knowledge of Regency HIG, there is no public or political opposition to the
Haynesville Expansion Project that would reasonably be expected to result in a material delay,

in this Agreement, no provision of this Agreement shall be construed to have any effect upon, or to
otherwise limit, any indemnification obligation or other provision contained in the Services
Agreement and the Company Partnership Agreement.

     Section 5.7 Indemnification Procedures.

          (a) Subject to the other provisions of this Article 5, in the event that any action,
suit, claim or proceeding is commenced by a third party involving a claim (a “Third Party Claim”)
in respect of any matter that, if true (without any responsibility for independent investigation of
the facts or law contained in such notice from the third party), would be subject to
indemnification by a Party under Section 5.2, Section 5.3 or Section 5.4
(an “Indemnifying Party”) to a Party entitled to such indemnification (an “Indemnified Party”), the
Indemnified Party shall promptly deliver written notice to the Indemnifying Party of such Third
Party Claim describing in reasonable detail (i) the nature of the Third Party Claim, (ii) if
practicable, the Indemnified Party’s best estimate of the amount of Losses attributable to the
Third Party Claim, (iii) the basis of the Indemnified Party’s request for indemnification under
this Agreement and (iv) a copy of all papers served with respect to such claim (if any) (the “Claim
Notice”). Failure to timely provide such Claim Notice shall not affect the right of the
Indemnified Party’s indemnification hereunder, except to the extent the Indemnifying Party is
prejudiced by such delay or omission.

          (b) If the Indemnifying Party notifies the Indemnified Party that the Indemnifying Party
elects to assume the defense of the Third Party Claim within 30 days of such Indemnifying Party’s
receipt of the Claim Notice (such election to be without prejudice to the right of the Indemnifying
Party to dispute whether such claim is an indemnifiable Loss under this Article 5), then
the Indemnifying Party shall have the right to defend such Third Party Claim with counsel selected
by the Indemnifying Party (who shall be reasonably satisfactory to the Indemnified Party), by all
appropriate proceedings, to a final conclusion or settlement at the discretion of the Indemnifying
Party in accordance with this Section 5.7(b). The Indemnifying Party shall have full
control of such defense and proceedings, including any compromise or settlement thereof; provided,
that the Indemnifying Party shall not enter into any settlement agreement without the written
consent of the Indemnified Party (which consent shall not be

22

 

unreasonably withheld, conditioned or delayed); provided further, that such consent shall not
be required if (i) the settlement agreement contains a complete and unconditional general release
by the third party asserting the claim of all Indemnified Parties affected by the claim and (ii)
the settlement agreement does not contain any sanction or restriction upon the conduct of any
business by any Indemnified Party or its Affiliates. If requested by the Indemnifying Party, the
Indemnified Party agrees to cooperate reasonably with the Indemnifying Party, at the Indemnifying
Party’s cost and expense, and its counsel in contesting any Third Party Claim which the
Indemnifying Party elects to contest, including the making of any related counterclaim against the
Person asserting the Third Party Claim or any cross complaint against any Person. The Indemnified
Party may participate in, but not control, any defense or settlement of any Third Party Claim
controlled by the Indemnifying Party pursuant to this Section 5.7(b), and the Indemnified
Party shall bear its own costs and expenses with respect to such participation.

          (c) If the Indemnifying Party does not notify the Indemnified Party within 30 days of such
Indemnifying Party’s receipt of the Claim Notice that the Indemnifying Party elects to defend the
Indemnified Party pursuant to Section 5.7(b), then the Indemnified Party shall have the
right to defend, and be reimbursed for its reasonable cost and expense (but only if the Indemnified
Party is actually entitled to indemnification hereunder) in regard to the Third Party Claim with
counsel selected by the Indemnified Party, by all appropriate proceedings, which proceedings shall
be prosecuted diligently by the Indemnified Party. In such circumstances, the Indemnified Party
shall defend any such Third Party Claim in good faith and have full control of such defense and
proceedings; provided, however, that the Indemnified Party may not enter into any compromise or
settlement of such Third Party Claim if indemnification is to be sought hereunder, without first
obtaining the written consent of the Indemnifying Party for such proposed settlement (which consent
shall not be unreasonably withheld, conditioned or delayed); provided further, that such consent
shall not be required if (i) the settlement agreement contains a complete and unconditional general
release by the third party asserting the claim of all Indemnifying Parties affected by the claim
and (ii) the settlement agreement does not contain any sanction or restriction upon the conduct of
any business by any Indemnifying Party or its Affiliates. The Indemnifying Party may participate
in, but not control, any defense or settlement controlled by the Indemnified Party pursuant to this
Section 5.7(c), and the Indemnifying Party shall bear its own costs and expenses with
respect to such participation.

          (d) Subject to the other provisions of this Article 5, a claim for indemnification by
any Indemnified Party for any matter not involving a Third Party Claim shall be asserted by
delivery of a Claim Notice to the Indemnifying Party from whom indemnification is sought promptly
after such Indemnified Party becomes aware of the facts or circumstances giving rise to such claim.

          (e) If Closing occurs, the Parties acknowledge that the Indemnified Subject Litigation is
comprised of Third Party Claims to which this Section 5.7 shall apply.

     Section 5.8 Limits on Indemnification.

          (a) Calculation of Losses. In calculating amounts payable to an Indemnified Party,
including for purposes of Section 5.8(d), the amount of any Losses for which an Indemnified
Party may receive any payment hereunder shall be determined without duplication

23

 

of any other Loss for which an Indemnified Party has received any payment hereunder and shall
be computed net of (i) payments actually recovered by the Indemnified Party under any insurance
policy with respect to such Losses, (ii) any indemnification or reimbursement payments actually
recovered by the Indemnified Party from any Person with respect to such Losses, (iii) any Tax
Benefit actually realized by any Indemnified Party on account of such Losses and (iv) any payment
made by Regency HIG under Section 5.9.

          (b) Limitation on Damages. Notwithstanding any other provision of this Agreement, in
no event shall any Party be liable for punitive, special, incidental, indirect, consequential or
lost profits damages of any kind or nature, regardless of the form of action through which such
damages are sought, except for any such damages recovered by any third party against any Party in
respect of which such Party would otherwise be entitled to indemnification pursuant to the terms
hereof.

          (c) Deductible. If the Closing occurs, none of the GE Covered Persons, the Alinda 1
Covered Persons or the Alinda 2 Covered Persons will be entitled to indemnity under Section
5.2 of this Agreement for Losses with respect to any claim under Section 5.2 until the
aggregate amount of all such claims by such GE Covered Persons, such Alinda 1 Covered Persons or
such Alinda 2 Covered Persons, as applicable, exceeds the applicable Regency HIG Basket Amount, and
thereafter, the Investor Covered Persons shall only be entitled to recover Losses in excess of the
applicable Regency HIG Basket Amount; provided that the foregoing limitation shall not apply with
respect to Losses arising out of or relating to (i) any breach of a Regency Fundamental
Representation, (ii) any breach of any of the covenants or agreements of Regency HIG contained in
this Agreement that are to be performed after the Closing other than the covenants in Section
6.3, (iii) any breach by Regency HIG of the representations and warranties in Section
3.12 or the covenants in Section 6.3 and (iv) the Indemnified Subject Litigation.

          (d) Cap. Notwithstanding anything to the contrary in this Agreement, if the Closing
occurs, in no event will the aggregate payments required to be made by Regency HIG in respect of
its aggregate liability to an Investor Covered Person arising under this Agreement exceed the
applicable Regency HIG Cap; provided that the foregoing limitation shall not apply with respect to
Losses arising out of or relating to (i) any breach of a Regency Fundamental Representation, (ii)
any breach by Regency HIG of any of the covenants or agreements in this Agreement that are to be
performed after the Closing other than the covenants in Section 6.3, (iii) any breach by
Regency HIG of the representations and warranties in Section 3.12 or the covenants in
Section 6.3 and (iv) the Indemnified Subject Litigation.

          (e) Exclusive Remedy. The remedies provided in this Article 5 shall be the
sole and exclusive legal remedies of the Investor Covered Persons, the Regency HIG Covered Persons
and the Covered Persons, from and after the Closing, with respect to this Agreement; provided that
nothing in this Section 5.8(e) shall prevent either Party from seeking specific
performance, injunctive and/or equitable relief for claims of breach or failure to perform
covenants performable under this Agreement at any time after the Closing.

     Section 5.9 Satisfaction of Claims for Indemnification. In lieu of making a direct payment to
an Investor Covered Person for any Losses suffered by an Investor Covered Person,

24

 

the Parties agree that in the event (i) any such Losses are determined to be subject to an
indemnification obligation pursuant to Section 5.2, (ii) such Losses are Losses both of the
Company and the Investors as a result of their ownership interests in the Company and (iii) neither
the Company nor RIGS is insolvent or will become insolvent after giving effect to all of such
Losses, Regency HIG shall satisfy any such Losses by contributing cash to the Company equal to 100%
of the Losses suffered by the Company, and each dollar paid by Regency HIG shall for all purposes
of this Agreement reduce the Regency HIG Cap by an aggregate amount of $1 (with each dollar of
reduction allocated among each Investor’s applicable portion of the Regency HIG Cap pro rata based
on such Investor’s applicable Sharing Ratio). For the avoidance of doubt, contributions made
pursuant to this Section 5.9 shall be treated as capital contributions under the Company
Partnership Agreement. Regency HIG shall not be issued any GP Units in respect of such contribution
to the Company.

     Section 5.10 Independent Investigation; Waiver of Other Representations.

          (a) EACH OF THE INVESTORS HEREBY ACKNOWLEDGES THAT (i) IT HAS MADE ITS OWN INDEPENDENT

ARTICLE 6

COVENANTS

     Section 6.1 Formation of the Company; Joinder; Related Matters.

          (a) Formation of the Company. Regency HIG agrees to cause the Company to be formed as
a Delaware general partnership prior to the Closing. The Parties agree that simultaneous with the
Closing, any Affiliate of Regency HIG that is a general partner in the Company will withdraw from
the Company.

          (b) Joinder of the Company. Prior to the Closing, Regency HIG shall cause the Company
to execute the joinder set forth on the signature pages of this Agreement.

          (c) Company Matters. The Parties agree that all representations and warranties that
relate to the Company and covenants and agreements of the Company set forth in this Agreement shall
not be given any effect for any time period beginning before the date the Company executes and
delivers the joinder referred to in Section 6.1(b).

     Section 6.2 Tax Effect. None of the Parties (nor such Parties’ counsel or accountants) has
made or is making any representations to any other Party (nor such Party’s counsel or accountant)
concerning any of the Tax effects of the transactions provided for in this Agreement. Each Party
hereto represents that it has obtained, or may obtain, independent Tax advice with respect thereto
and upon which it, if so obtained, has solely relied.

     Section 6.3 Tax Matters.

          (a) Each of the Parties agrees to cooperate fully with each other Party to enable each Party
to determine its own Tax liability with respect to the Company accurately. Each Party shall
provide and make available to each other Party such records as a Party may reasonably request for
the defense of any audit, examination, administrative appeal or litigation of any Tax Return or
other similar governmental report or form.

27

 

          (b) Regency HIG shall be liable for, and shall indemnify, defend and hold harmless the Company
for, any and all liability for Taxes with respect to RIGS and the ownership or operation of the
Assets or the RIGS Interests for any taxable period ending on or
before the Closing Date (“Pre-Closing Tax Period”) and with respect to any taxable period that
begins on or before and ends after the Closing Date (“Straddle Period”), for the portion thereof
ending at the close of business on the Closing Date. In the case of any Straddle Period, liability
for Income Taxes relating to RIGS or the ownership or operation of the Assets or the RIGS Interests
shall be allocated between Regency HIG and the Company as if all of the books and records relating
to RIGS and the ownership and operation of the Assets were closed as of the close of business on
the Closing Date. In the case of any Straddle Period, the amount of any Non-Income Taxes with
respect to RIGS or the Assets allocable to the portion of the Straddle Period ending on the Closing
Date shall be deemed to be the amount of such Taxes for the entire period (or, in the case of such
Taxes determined on an arrears basis, the amount of such Taxes for the immediately preceding
period) multiplied by a fraction, the numerator of which is the number of calendar days in the
applicable period ending on and including the Closing Date and the denominator of which is the
number of calendar days in the entire relevant period. In the case of ad valorem property Taxes,
“taxable period” means the period beginning on the assessment date for ad valorem property Taxes
through the day before the next assessment date for such Taxes. Upon receipt of the ad valorem
property Tax bills for the taxable period that contains the Closing Date, Regency HIG shall
calculate the prorated ad valorem property Taxes and shall bill the Company for the amount
allocated to the post-Closing period, with the Company making such payment within 20 days of
receipt of such bill. The Company shall promptly forward to Regency HIG any ad valorem property
Tax bills for the taxable period that contains the Closing Date that are received by the Company.
Regency HIG shall be responsible, as between Regency HIG and the Company, for the payment of the
total amount of ad valorem property Taxes imposed on or with respect to the Assets for the taxable
period that contains the Closing Date. Notwithstanding any provision of this Agreement to the
contrary, any Tax receivables included within Current Assets shall be for the benefit of the
Company and shall not reduce or offset any obligation of Regency HIG for Taxes regardless of the
period to which such receivable relates. The Company shall prepare and file all Tax Returns with
respect to RIGS and the ownership or operation of the Assets due after the Closing Date and Regency
HIG shall fully cooperate with the Company, at its own cost, in the preparation of such Tax Returns
relating to any Straddle Period.

     Section 6.4 Further Assurances. From time to time after the Closing Date, and without any
further consideration, the Parties agree to execute and deliver all such additional instruments and
documents, and will do all such other acts and things, all in accordance with applicable Laws, as
may be reasonably necessary to give effect to the transactions consummated by this Agreement.

     Section 6.5 Expenses. Except as otherwise provided in this Section 6.5, each Party
shall bear its own expenses incurred in connection with the Transaction Documents and the
Transactions whether or not the Transactions are consummated, including all fees of its legal
counsel, financial and business advisers and accountants; provided that Regency HIG shall reimburse
the Alinda Investors for reasonable and documented third party expenses paid in connection with the
Transaction Documents and the Transactions if this Agreement is terminated by any Alinda Investor
pursuant to Section 8.1(b). Regency HIG shall bear all transfer, recording, sales and

RIGS, to the offices, properties, books and records of RIGS and to any personnel that provide
services to RIGS, and will furnish each Investor with such additional information concerning the
Company, RIGS, the Business and the Assets as may be reasonably requested, but only to the extent
such information is in the possession of Regency HIG or any of its Affiliates or is otherwise
readily available. Notwithstanding the foregoing, (i) the Investors shall have no right of access

to bids received from others in connection with any of the transactions contemplated by this
Agreement and information and analysis (including financial analysis) relating to such bids, (B)

with the Alinda Investors in order to finalize and close the Transactions. Each of Regency HIG and
the GE Investor agrees (i) to discontinue all discussions with any Person other than the Alinda
Investors concerning any transaction or series of transactions that would impede or preclude the
Transactions being consummated with the Alinda Investors and (ii) none of Regency HIG, the GE
Investor or any of their respective affiliates, officers, employees, directors, stockholders,
advisers and representatives will, directly or indirectly, solicit or otherwise

31

 

encourage the

Investors concerning, or enter into any agreement with respect to the Transactions,
directly or indirectly, or any other transaction that could impede or preclude the
Transactions being consummated with Alinda Investors.

     Section 6.11 Alinda Capital Call. Upon the first Business Day after the Regency Conditions

Parallel Fund GP II, L.P., respectively, to (a) make the requisite capital call pursuant to the
Organizational Documents of Alinda Infrastructure Fund II, L.P. and Alinda Infrastructure Parallel
Fund II, L.P., respectively, necessary to fully satisfy and discharge each of the Alinda Investor’s
payment obligations set forth in Article 2. The Alinda Investors shall notify Regency HIG
when such capital call has been made.

     Section 6.12 Expenses Paid Post-Closing. The Parties agree that all costs incurred after the
Closing in connection with the Haynesville Expansion Project that are approved pursuant to the
Company Partnership Agreement or the Services Agreement shall be borne exclusively by the Company
or RIGS. To the extent any such costs (a) are paid by the MLP or any of its Affiliates (other than
the Company and RIGS) after the Closing and (b) are not otherwise reimbursed to such Person
pursuant to Section 2.1, the Company agrees to reimburse such Person promptly after such
Person provides the Company with documentation that reasonably supports the payment of such costs.

     Section 6.13 Historical Financial Statements. In connection with a financing transaction
approved by the Management Committee, Regency HIG agrees that it will use commercially reasonable
efforts to assist a nationally recognized accounting firm in the preparation of up to three years
of audited historical financial statements of the Company and/or RIGS; provided that the Company
shall reimburse Regency HIG and/or its Affiliates for all costs associated with the preparation of
such historical financial statements, including all third party costs and any portion of internal
costs that are allocable to the preparation of such financial statements.

knowing and intentional misrepresentation or omission of a material fact or willful or intentional
breach of this Agreement, including attorneys’ fees and the right to pursue any remedy at law or in

be invalid, illegal, void or unenforceable in any respect, all other provisions of this Agreement,

has been held invalid, illegal, void or unenforceable, shall nevertheless remain in full force and
effect and will in no way be affected, impaired or invalidated thereby. Upon such determination

not give rise to any right of recourse against any directors, members, managers, stockholders,
owners, officers, partners, employees, agents, consultants, attorneys or representatives of any
Party, but nothing herein shall limit any obligation of the Alinda Investor I Parent as set forth

Parent Guarantee.

     Section 9.12 Entire Agreement; Supersedure. This Agreement and the instruments referenced

and such instruments contain the entire understanding of the Parties with respect to the subject

written, is intended to be or shall be included in or form part of this Agreement unless it is
contained in a written amendment hereto executed by the Parties after the Execution Date.

     Section 9.13 Disclosure Schedules. The inclusion of any information (including dollar
amounts) in any of the disclosure schedules attached hereto (collectively, the “Disclosure
Schedules”) shall not be deemed to be an admission or acknowledgment by any Party that such
information is required to be listed on such section of the relevant Disclosure Schedules or is
material to or outside the ordinary course of business of such Party. The information contained in
this Agreement, the Exhibits hereto and the Disclosure Schedules are disclosed solely for purposes
of this Agreement, and no information contained herein or therein shall be deemed to be an
admission by any Party to any third party of any matter whatsoever (including any violation of any

the Closing, Regency HIG shall notify Investors of any changes, additions, or events which cause
any material change in or addition to the Disclosure Schedules promptly in the event Regency HIG
becomes aware of the same by delivery of appropriate updates to the Disclosure Schedules to the
Investors. Such supplemental disclosures shall amend and supplement the Disclosure Schedules
delivered on the Execution Date for all purposes only if Closing occurs.

          (a) Each of the Parties agrees that it has been represented by independent counsel of its
choice during the negotiation and execution of this Agreement and the documents referred to herein,
and that it has executed the same upon the advice of such independent counsel. Each Party and its
counsel cooperated in the drafting and preparation of this Agreement and the documents referred to
herein, and any and all drafts relating thereto shall be deemed the work product of the Parties and
may not be construed against any Party by reason of its preparation. Therefore, the Parties hereto
waive the application of any law, regulation, holding
or rule of construction providing that ambiguities in an agreement or other document will be
construed against the Party drafting such agreement or document.

38

 

          (b) Each of the Investors and the Company acknowledge that Vinson & Elkins L.L.P. has been and
is solely representing the MLP, Regency HIG and Regency Employees Management LLC and not any

     WHEREAS, Alinda Gas Pipeline II, L.P. (“Alinda Investor 2”) has entered into the
Contribution Agreement dated as of February 26, 2009 (the
“Contribution Agreement”) by and
among the Beneficiary, General Electric Capital Corporation, Alinda Gas Pipeline I, L.P.
(“Alinda Investor 1”) and Alinda Investor 2;

     WHEREAS, it is a condition precedent under the Contribution Agreement that Guarantor, as an
affiliate of Alinda Investor 2, provide a guaranty to the Beneficiary on the terms and conditions
hereinafter provided; and

     WHEREAS, Guarantor is willing to enter into this Guaranty to induce the Beneficiary to enter
into the Contribution Agreement, execute the transactions referred to therein and cause the

and unconditionally guarantees the due and punctual payment and performance of the obligations of
Alinda Investor 2 under and in accordance with the Contribution Agreement (such payment and
performance obligations, collectively, the “Guaranteed Obligations”). To the extent that
Alinda Investor 2 fails to pay or perform any Guaranteed Obligation when due, Guarantor shall
promptly pay to the Beneficiary the amount due with respect to such Guaranteed Obligation in cash
or otherwise perform such Guaranteed Obligation, without demand or notice whatsoever. This Guaranty
shall constitute a guarantee of payment and not of collection. The liability of Guarantor under the
Guaranty shall be subject to the following:

	 	a)	 	Subject to Section 1(c), this Guaranty shall terminate and be of no

	 	b)	 	Guarantor shall be subrogated to all rights of the Beneficiary in
respect of any amounts paid by Guarantor pursuant to the provisions of this

subrogation until after the indefeasible payment in cash and performance in full of
the Guaranteed Obligations;
	 
	 	c)	 	This Guaranty shall continue to be effective or be reinstated, as the
case may be, if at any time any payment of any Guaranteed Obligation is rescinded
or must otherwise be returned by the Company (as defined in the Contribution
Agreement) or the Beneficiary, whether as a result of the insolvency, bankruptcy or
reorganization of Guarantor or Alinda Investor 2 or otherwise, all as though such
payment had not been made.

-B-2-1-

 

     Section 2. Obligations Unconditional. Guarantor hereby agrees that its obligations

the Guaranteed Obligations or any security therefor, if any, shall be released or
exchanged in whole or in part or otherwise dealt with; or
	 
	 	d)	 	the release of any other guarantor providing a guaranty pursuant

power or remedy or proceed against Alinda Investor 2 under the Contribution Agreement or any other
agreement or instrument referred to therein, or against any other person under any other guarantee
of, or security for, any of the Guaranteed Obligations. The Guarantor waives any and all notice of
the creation, renewal, extension, waiver, termination or accrual of any of the Guaranteed
Obligations and notice of or proof of reliance by the Beneficiary or the Company upon this Guaranty
or acceptance of this Guaranty, and the Guaranteed Obligations, and any of them, shall conclusively
