[¶ 1] Passamaquoddy Tribe appeals from a judgment entered in the Superior Court (Cumberland County, Mills, J.), following a jury-waived trial, granting recovery to Forrest Associates on its claims of breach of contract and unjust enrichment in the amount of $42,449.81. On appeal, the Tribe contends that no contract existed and that Forrest Associates was not entitled to recovery in either quantum meruit or unjust enrichment. We agree and vacate the judgment.
I. CASE HISTORY
[¶ 2] Forrest Associates is a Maine corporation that provides management consulting services and engages in market feasibility studies and project development work. In early 1994, Mark Stickney, a Forrest employee, and Thomas Tureen, legal counsel and advisor to the Tribe, discussed whether Forrest Associates could assist the Tribe in the development of a high stakes bingo operation in Albany Township, Oxford County, Maine. Forrest conducted a market assessment of the operation and submitted it, along with a description of Forrest’s proposed involvement in the project, to Tureen in the form of an engagement letter. The letter set forth Forrest’s proposed role in all phases of the project and provided Forrest’s estimate of its fees and expenses. The letter stated that Forrest agreed to postpone receipt of its fees and expenses for the initial phase of the project, but noted that “[u]pon completion of this phase of the project, it is understood that we will be paid in full for Phase One.” William Forrest, founder and chief executive officer of Forrest Associates, testified at trial that Tureen said that Forrest Associates “would be required to complete this [initial] phase of the project on spec.” That is, “rather than having the tribe commit to *1043 paying the 10 to $15,000 upon completion of the project, [Forrest Associates] would have to assume that risk and ... it would be paid provided the tribe decides to proceed with the project.” 1 Forrest asked the Tribe to sign the engagement letter. The Tribe never did.
[¶ 3] During this initial phase, Tureen asked Forrest to perform some minor additional work that included an assessment of additional revenue opportunities such as off-track betting. Forrest performed the additional work and drafted a revised market assessment. In July 1994, Tureen told Forrest that the Tribe wished to proceed with the project and that Forrest should develop a comprehensive business plan. Forrest then developed a plan that further defined the scope of the project and contained a comprehensive financial schedule that addressed anticipated costs, revenues, and expenses of development. Tureen again told Forrest that if the Tribe chose to proceed with the project, “the fees that had been incurred on spec would be paid,” and that any subsequent fees would be paid as the project progressed. Forrest submitted the plan to the Tribal Council at a meeting in August 1994.
[¶ 4] The plan was discussed in detail at the August meeting. In general terms, the plan described Forrest’s involvement in each stage of the development and operation of the enterprise. It also contained construction and management budgets that included Forrest’s historical and prospective fees. Forrest expected to perform work on the project through August 1995 at a cost to the Tribe of $228,960, with 35-40% of that total representing Forrest’s anticipated profits. The Tribe did not object to either the work Forrest was to perform or the rates Forrest was to charge.
[¶ 5] When Forrest presented the plan to the Council, Tureen asked whether Forrest understood that payment for the initial phase of the project was on a contingent basis such that Forrest would only be paid if the Tribe developed the project. William Forrest responded that he understood that the “recapture of those fees is provided that the project turns into a reality.” William Forrest also indicated that the project needed an immediate infusion of funds from the Tribe. The Council, however, was reluctant to make a financial contribution at that time. A Council member then made a motion “to proceed with pursuing this with Forrest Associates and resolve the contribution questions for later.” Tureen then suggested “that we proceed in accordance with the plan submitted, which doesn’t commit you [the Tribe] today that you would need money, and then the understanding is that there will be a more formal agreement with you later.” The motion was approved.
[¶ 6] The more formal agreement alluded to never materialized. Nevertheless, Forrest continued to work on the project *1044 by soliciting bids from engineers, researching and obtaining presentations from architects, and locating financing for the project. In November 1994, however, the Tribe told Forrest that it would not provide any short-term funding and that weather considerations would soon stop work on the project for the winter. William Forrest testified that he did not believe Forrest performed any work for the Tribe after 1994. The Tribe never paid Forrest for any work, and the facility was never built.
[¶ 7] In 1996, the Tribe obtained a financing commitment for the project from Snake River Financing, Ltd. The Tribe contends that it did not use any of Forrest’s work product in obtaining the financing, and that in fact the two projects were substantially dissimilar. Forrest, however, contends that the development costs were virtually the same as the costs in its proposal, and that the Tribe had continued access to the Forrest proposal when making all design decisions for the Snake River facility. Despite the Tribe’s financing agreement with Snake River, the facility has not been bruit because opponents of the project successfully challenged regulatory approval on the ground that the facility would not be erected on “Indian land.” We affirmed in
Kimball v. Land Use Regulation Comm’n,
[¶ 8] In 1997, Forrest brought this suit. The Superior Court (Cumberland County,
Mills,
/.) granted the Tribe’s motion for summary judgment on the ground that both the alleged contract and Forrest’s claims for quantum meruit were barred by 25 U.S.C. § 81 (1983) because they dealt with services to the Tribe relative to their lands and the contract was not approved by the Secretary of the Interior and the Commissioner of Indian Affairs. We vacated and remanded because section 81 does not apply to an agreement concerning land not held in trust by the United States.
See Forrest Assocs. v. Passamaquoddy Tribe,
II. BREACH OF CONTRACT
[¶ 9] The establishment of a contract requires that the parties mutually assent “to be bound by all its material terms; the assent must be manifested in the contract, either expressly or impliedly; and the contract must be sufficiently definite to enable the court to determine its exact meaning and fix exactly the legal liabilities of the parties.”
VanVoorhees v. Dodge,
[¶ 10] Forrest presented the plan to the Council at the August meeting. The plan was discussed in detail. The plan described Forrest’s duties and obligations for the project, established a payment schedule for Forrest’s fees, and further outlined the scope of the project’s development and operation. At the conclusion of the meeting, however, the Tribe voted to move forward with planning for the project with the caveat that any responsibility of the Tribe to contribute its resources for work already performed would be revisited in a more formal agreement at a later
*1045
date. This evidence establishes that the Tribe did not intend to be bound by the vote alone. In effect, therefore, all that existed between the parties was an agreement to work towards an agreement. Such an agreement is unenforceable.
See Ault v. Pakulski,
III. QUANTUM MERUIT
[¶ 11] Quantum meruit describes the extent of liability under a quasi-contract theory and therefore involves the “recovery for services or materials provided under an implied contract.”
Bowden v. Grindle,
[¶ 12] Forrest has failed to establish that it possessed a reasonable expectation of payment. The evidence demonstrates that Forrest provided its services “on spec.” Forrest conceded that payment was contingent on the project turning into a reality. That reality never occurred. Accordingly, Forrest is not entitled to a recovery in quantum meruit because it cannot establish a reasonable expectation of payment.
[¶ 13] In addition, Maine law provides that the Tribe enjoys the same privileges and immunities as a municipality.
3
Municipalities are not liable for the payment of unauthorized services.
See A.F.A.B., Inc. v. Town of Old Orchard Beach,
IV. UNJUST ENRICHMENT
[¶ 14] To sustain a claim for unjust enrichment, a claimant must estab
*1046
lish “that it conferred a benefit on the other party ... that the other party had ‘appreciation or knowledge of the benefit’ ... and ... that the ‘acceptance or retention of the benefit was under such circumstances as to make it inequitable for it to retain the benefit without payment of its value.’ ”
Howard & Bowie v. Cloutier & Briggs,
[¶ 15] In the present case, it is unclear which theory the Superior Court relied on in granting Forrest’s recovery. The judgment concludes that the Tribe “was aware of [Forrest’s] work and has retained the benefit of that work,” thereby referencing the elements of unjust enrichment, yet then relies on a case decided in quantum meruit in support of its conclusion.
See Matthews v. Neal, Greene & Clark,
The entry is:
Judgment vacated.
Notes
. The Tribe contends that the Superior Court erred by admitting Tureen’s statements. We review the trial court’s evidentiary rulings for clear error and an abuse of discretion.
See Maine Shipyard & Marine Ry. v. Lilley,
The record established that Tureen served as the Tribe’s long-time legal counsel, that Tureen met with Forrest throughout the initial phase of the project and that Forrest performed work at Tureen’s request, and that Tureen told Forrest that the Tribe wanted to proceed with the project. Competent evidence exists in the record to support these factual determinations, and thus they are not clearly erroneous. Consequently, the Superi- or Court did not abuse its discretion by admitting Tureen’s statements.
. Forrest contends in its cross-appeal that it is entitled to recover lost profit damages resulting from the Tribe’s breach of contract. Because we conclude that no contract arose between the parties, however, Forrest is not entitled to recovery.
. See 30 M.R.S.A. § 6206(1) (1996). Section 6206 provides, in pertinent part, that "the Passamaquoddy Tribe and the Penobscot Nation, within their respective Indian territories, shall have, exercise and enjoy all the rights, privileges, powers and immunities ... and shall be subject to all the duties, obligations, liabilities and limitations of a municipality ...."Id.
