            sum payment equal to _______ times Executive's monthly base salary
            at the time of termination.

      (c)   Death or Disability. This Agreement terminates (1) if Executive dies

            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
            Employer. If termination occurs under this Section 8(c), Executive

            (1)   Willful misfeasance or gross negligence in the performance of

                  reasonably determined on the advice of legal counsel by
                  Employer's board of directors.

                  any compensation or benefit plan benefiting Executive, unless

                  substantially all of Employer's employees (or employees of a
                  successor or controlling entity of Employer) formerly
                  benefited;

            (2)   A relocation or transfer of Executive's principal place of
                  employment that would require Executive to commute on a

                  CSB-Hamilton's present main office location.

9.    CONFIDENTIALITY. Executive will not, after the date this Agreement is
      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 Employer or Glacier or their business operations,

      confidential information; (b) the use or disclosure is consistent with
      Executive's duties under this Agreement; (c) disclosure is required by law
      or court order; or (d) the information is made or otherwise becomes

      includes, without limitation, trade secrets, 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 Employer or Glacier. 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 Employer has ended,
            Executive will not, directly or indirectly, as a shareholder,
            director, officer, employee, partner, agent, consultant, lessor,
            creditor or otherwise, provide management, supervisory or


                                       4
<PAGE>

                                                                    EXHIBIT 10.4

            other similar services to any person or entity engaged in any
            business within _________ County, Montana, that is competitive with
            the business of Employer or Glacier 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 bank.

      (b)   Non-Interference. For so long as Executive is employed by Employer
            or Glacier and for one year following termination of Executive's
            employment, Executive will not, directly or indirectly, persuade or
            entice, or attempt to persuade or entice, (i) any employee of
            Employer or Glacier to terminate his/her employment with Employer or
            Glacier, or (ii) any person or entity to terminate, cancel, rescind
            or revoke its business or contractual relationships with Employer or
            Glacier.

11.   ENFORCEMENT.

      (a)   Employer and Executive stipulate that, in light of all of the facts
            and circumstances of the relationship between Executive and
            Employer, 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 Employer's and
            Glacier'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
            Employer request the court to reform these provisions to restrict
            Executive's use of confidential information and Executive's ability
            to compete with Employer and Glacier to the maximum extent, in time,
            scope of activities, and geography, the court finds enforceable.

      (b)   Executive acknowledges that Employer and Glacier 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, Employer, 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 Employer 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
      Employer 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 Employer's enforcement of a remedy by way of injunction
      will not prevent Executive from earning a livelihood.

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

      (c)   Exception to Arbitration. Notwithstanding the above, if Executive
            violates Section 9 or 10, Employer 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
            [CDC Bank's],[GBCI Bank's], Glacier'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, that 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.

      (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. Employer or
            Glacier may assign this Agreement to a wholly owned subsidiary of
            Glacier.

      (f)   Amendment. This Agreement may be modified only through a written
            instrument signed by all 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 Montana 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 Missoula County, Montana.

      (i)   Counterparts. This Agreement may be executed in one or more
            counterparts, including by facsimile, 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.
