    I.    INTRODUCTION
    Williams Alaska Petroleum owned and operated a refinery, which
    ConocoPhillips Alaska supplied with crude oil pursuant to an Exchange Agreement.
    ConocoPhillips demanded that Williams tender a payment of $31 million as adequate
    assurances of Williams’s ability to perform if an ongoing administrative rate-making
    process resulted in a large retroactive increase in payments that Williams would owe
    ConocoPhillips under the Exchange Agreement. ConocoPhillips offered to credit
    Williams with a certain rate of interest on that principal payment against a future
    retroactive invoice. Williams transferred the principal of $31 million but demanded,
    among other terms, credit corresponding to a higher rate of interest. Williams stated that
    acceptance and retention of the funds would constitute acceptance of all of its terms.
    ConocoPhillips received and retained the funds, rejecting only one particular term in
    Williams’s latest offer but remaining silent as to which rate of interest would apply.
    Years later, after the conclusion of the regulatory process, ConocoPhillips invoiced
    Williams retroactively pursuant to the Exchange Agreement. ConocoPhillips credited
    Williams for the $31 million principal already paid as well as $5 million in interest on
    that principal calculated using the lower of the two interest rates. Williams sued
    ConocoPhillips, arguing that a contract had been formed for the higher rate of interest
    and that it was therefore owed a credit for $10 million in interest on the $31 million
    principal.
    On cross-motions for summary judgment, the superior court initially ruled
    for Williams, concluding that a contract for the higher rate of interest had formed under
    the Uniform Commercial Code (UCC) § 2-207(1) when ConocoPhillips retained the $31
    million while rejecting one offered term but voicing no objection to Williams’s specified
    interest term. On a motion for reconsideration, the superior court again ruled for
    Williams, this time determining that a contract for the higher rate of interest had formed
    based on the behavior of the parties after negotiation under UCC § 2-207(3), or, in the
    alternative, that Williams was entitled to a credit for a different, third rate of interest in
    -2-                                        6874
    quantum meruit. The superior court also ruled in favor of Williams on all issues related
    to attorney’s fees and court costs.
    ConocoPhillips and Williams both appeal. We conclude that the superior
    court was right the first time and that the parties entered into a contract for the higher rate
    of interest under UCC § 2-207(1). Thus, it was incorrect for the superior court to rescind
    its initial summary judgment order as improvidently granted. Accordingly, we do not
    reach the UCC § 2-207(3) or quantum meruit holdings of the superior court’s order on
    reconsideration. Finally, we affirm all of the superior court’s actions with regard to
    attorney’s fees and court costs.
    II.    FACTS AND PROCEEDINGS
    A.     Facts
    1.      The parties and the contract
    In December 1999, BP Oil Supply Company and Williams Energy
    Marketing & Trading Company entered into a contract for the sale of crude oil, called
    an Exchange Agreement. Within months, the rights and duties of the original parties to
    this Exchange Agreement were assigned to the parties to the present case:
    ConocoPhillips and Williams.
    Under the Exchange Agreement, ConocoPhillips would provide Williams’s
    refinery at North Pole with crude oil from the Trans-Alaska Pipeline System. Williams
    would extract valuable components from the crude oil and provide an equal volume of
    lower-quality crude back to ConocoPhillips, and ConocoPhillips would then return the
    crude oil to the pipeline. The Trans-Alaska Pipeline System operates a “Quality Bank,”
    which compensates all pipeline shippers for the degradation in the average quality of
    crude in the pipeline downstream caused by tender of less-valuable crude upstream. The
    Quality Bank Administrator assesses “degradation charges” to shippers tendering
    comparatively lower-value crude to the pipeline based on a quality pricing scheme set
    -3-                                         6874
    by the Federal Energy Regulatory Commission (FERC) and the Regulatory Commission
    of Alaska (RCA). ConocoPhillips, as the shipper tendering lower-quality crude back into
    the pipeline, would be assessed degradation charges by the Administrator.            The
    Exchange Agreement’s pricing provision, on top of a flat per-barrel fee, required
    Williams to reimburse ConocoPhillips for such degradation charges, including any
    retroactive adjustments resulting from new FERC regulations.
    The Exchange Agreement contained two additional provisions relevant to
    this case. First, an adequate-assurances clause specified that when one party “has
    reasonable grounds for insecurity,” that party may demand “adequate security for, or
    assurances of [the other party’s] ability to perform, all of its obligations under the
    Agreement.” If adequate security or assurances were not forthcoming within 48 hours,
    the demanding party would “have the right to liquidate the Agreement” and cease
    performance of its other obligations under the Exchange Agreement. Second, a signed-
    writing clause specified that “[n]o changes, alterations, or modifications . . . of the
    Agreement shall be effective unless agreed to in writing by an authorized representative
    of the Parties.”
    2.    The dispute
    In 2002, ConocoPhillips believed that it had reasonable grounds for
    insecurity. The FERC and the RCA initiated a regulatory rate-making process that could
    result in a retroactive increase in Quality Bank degradation charges to ConocoPhillips
    for its tender of lower-quality crude back into the pipeline. Under the pricing provision
    of the Exchange Agreement requiring reimbursement for retroactive degradation charges,
    Williams could owe ConocoPhillips substantial sums of money, the precise amount of
    which would depend on the agencies’ promulgation of a revised pricing scheme, perhaps
    years in the future. ConocoPhillips, believing Williams and its parent company to be in
    a precarious financial position, doubted Williams’s ability to pay a large, retroactively
    -4-                                     6874
    assessed charge in the future. Invoking the adequate-assurances provision of the
    Exchange Agreement, ConocoPhillips sent Williams an initial demand letter on
    October 4 stating its position that Williams “now owes” $31,268,645 in “Quality Bank
    adjustments to the price of oil” already exchanged over the prior two years under the
    contract. ConocoPhillips proposed a range of options for providing adequate financial
    assurances: a cash payment, a trust with ConocoPhillips as beneficiary, a letter of credit,
    or a senior security interest in Williams’s property. This letter did not mention whether
    or at what rate ConocoPhillips would credit Williams for interest on any such assurance
    payment or security.
    Following a series of telephone calls, Williams sent ConocoPhillips a letter
    on October 8. Williams disputed that it was in financial peril or that ConocoPhillips had
    reasonable grounds for insecurity. Williams also stated its view that potential future
    Quality Bank adjustments “are not currently due,” as ConocoPhillips would have it, but
    rather “may become due in the future upon resolution of the Quality Bank proceedings.”
    Nonetheless, fearing the harm that would come from ConocoPhillips halting the flow of
    crude, Williams offered to settle the dispute in a package deal that included, among other
    terms, wire transfer of $29.01 million to ConocoPhillips. This principal, plus interest
    that would accrue on the principal “calculated at the LIBOR six-month rate,”1 would be
    “held by ConocoPhillips for Williams’[s] account” pending a resolution in the rate-
    making case, at which point “the advance payments to ConocoPhillips, including all
    interest thereon, will be applied toward any Quality Bank Amounts so determined to be
    due from Williams.” On October 11, ConocoPhillips responded, saying it might be
    willing to meet some of Williams’s conditions for settlement but demanding a payment
    1
    LIBOR, or the London Interbank Offered Rate, is the interest rate that large
    London banks charge each other for short-term loans.
    -5-                                       6874
    of $35,245,181. The letter made no mention of Williams receiving credit for interest on
    that sum in the future. In a follow-up letter dated October 17, ConocoPhillips proposed
    that Williams pay $35,245,181 “as a partial preliminary settlement payment” of any
    retroactively assessed Quality Bank degradation charges.            For the first time,
    ConocoPhillips offered to credit Williams for interest earned on the principal at the
    LIBOR rate.
    On October 18, Williams wired $31,268,645 to ConocoPhillips. Later that
    day, Williams sent ConocoPhillips a letter stating that the money was intended to
    “avoid[] litigation and resolv[e] the disputes” over retroactive price modifications under
    the Exchange Agreement. Williams specified that “ConocoPhillips’[s] receipt and
    retention of the $31,268,645 . . . shall constitute ConocoPhillips’[s] agreement with the
    terms set forth in . . . this letter.”   The letter’s terms included three substantive
    provisions: (1) that the “full principal amount” already wired to ConocoPhillips receive
    interest at a “rate prescribed by FERC”2 and that the principal and interest would be held
    by ConocoPhillips for Williams’s account and later be credited toward any final
    retroactive assessments; (2) that ConocoPhillips agree to “continue good faith efforts”
    in “vigorous support” of a preexisting joint-negotiating agreement that would present a
    united front in the FERC rate-making case; and (3) that the parties agree to keep the
    agreement “in strictest confidence.”
    On October 29, ConocoPhillips responded, acknowledging that it had
    “received and retained the Payment as a preliminary partial settlement,” using language
    mirroring Williams’s specification of the mode of acceptance of the terms in its
    October 18 letter. ConocoPhillips stated that it “does not agree with all of the terms
    2
    The parties expected the FERC to impose interest on any retrospectively
    assessed degradation charges. The FERC rate imposed by regulation was expected to
    be substantially higher than the LIBOR rate.
    -6-                                      6874
    stated in [Williams’s October 18 letter]” and “also do[es] not believe it would prove
    productive to conduct a letter writing campaign as to what the Payment represents or
    specific terms and conditions associated with the Payment.” ConocoPhillips did object
    to one term in particular. It noted that it would voluntarily continue to support the joint-
    negotiating efforts in front of the FERC under the terms of the preexisting agreement on
    the issue, but it denied “[any] linkage whatsoever between ConocoPhillips[’s] right to
    adequate assurance under the Agreement and ConocoPhillips’[s] performance with
    respect to” the independent joint-negotiating agreement. ConocoPhillips did not address
    the issue of whether or at what rate the cash payment would accrue interest.
    After ConocoPhillips’s October 29 letter, there was no further
    communication between the parties about the principal payment or accrual of interest
    until the FERC rate-making case finally came to a close in July 2007. In August 2007,
    ConocoPhillips invoiced Williams for reimbursement of the retroactively assessed
    Quality Bank degradation charges amounting to over $167 million, giving Williams
    credit for the $31 million prepayment as well as accrued interest at the LIBOR rate
    amounting to an additional $5 million, yielding a final billed amount of $131 million.
    Williams paid ConocoPhillips about $5 million less than the invoiced amount, claiming
    it deserved credit on the $31 million prepayment at the (higher) FERC interest rate which
    would amount to a $10 million interest credit. ConocoPhillips responded by revising its
    invoice to give no credit for any interest on the $31 million prepayment, claiming that
    no agreement had been reached on the issue.

    B.     Judicial Proceedings And The Superior Court’s Holdings
    Litigation ensued,3 and in 2009 both parties moved for summary judgment
    on the effect of the October 2002 correspondence with respect to interest credits. Both
    parties agreed that “no issues of material fact prevent[ed] summary resolution of that
    issue.” The superior court applied Ohio’s substantive contract law pursuant to the
    Exchange Agreement’s choice-of-law provision and found that there was no conflict
    with Alaska law because both states had adopted the Uniform Commercial Code.
    The superior court granted summary judgment to Williams. The superior
    court concluded that under the Uniform Commercial Code §§ 2-207(1) & (2)4 the

    In September 2007, the parties entered into a Quality Bank Interest Dispute
    Resolution Agreement in which the parties agreed to “jointly file for a Declaratory
    Judgment Order” and to limit discovery and briefing. As relevant to the attorney’s fee
    dispute in this case, the parties also agreed that “[t]he prevailing Party in the Declaratory
    Judgment proceeding shall be entitled to recover reasonable attorney fees and court
    costs” to be “paid within twenty (20) days after receipt of an invoice for such costs
    containing documentation reasonably supporting the amounts.”

    Sections 2-207(1) & (2) of the Uniform Commercial Code, codified and
    slightly amended at Ohio Rev. Code Ann. § 1302.10(A) & (B) (West 2013), state:
    (1)    A definite and seasonable expression of acceptance or
    a written confirmation which is sent within a reasonable time
    operates as an acceptance even though it states terms
    additional to or different from those offered or agreed upon,
    unless acceptance is expressly made conditional on assent to
    the additional or different terms.
    (2)    The additional terms are to be construed as proposals
    for addition to the contract. Between merchants such terms
    become part of the contract unless:
    (a)     the offer expressly limits acceptance to the
    terms of the offer;

    -8-                                        6874
    October 18 and October 29 letters modified the Exchange Agreement and that the
    resulting contract required ConocoPhillips to credit Williams with interest on the
    prepayment at the higher FERC interest rate proposed by Williams in its October 18
    letter. ConocoPhillips’s October 29 reply letter constituted a “definite and seasonable
    expression of acceptance” of Williams’s October 18 offer. Because ConocoPhillips
    acknowledged receipt and retention of the $31 million prepayment, mirroring the
    conditions of acceptance in Williams’s October 18 offer, and explicitly objected to only
    one term of the offer, while remaining silent as to interest and otherwise just hinting at
    unspecified additional quibbles, the court found that ConocoPhillips “grudgingly but
    definitively assented” to Williams’s reasonable proposal of FERC interest.
    Neither party had briefed the application of UCC § 2-207. ConocoPhillips
    moved for reconsideration, and the superior court ordered further briefing. The superior
    court concluded that it “improvidently granted summary judgment that a contract was
    formed pursuant to [UCC § 2-207(1)]” because ConocoPhillips’s “express rejection of
    Williams’s joint-negotiating provision” renders disputable the material factual inference
    that ConocoPhillips’s letter of October 29, 2002 was a definite and seasonable
    expression of acceptance. Nevertheless, the court again granted summary judgment for
    Williams, this time concluding that the parties’ behavior after October 2002 created an
    implied-in-fact contract under UCC § 2-207(3)5 and that one of the terms of that contract

    Section 2-207(3) of the UCC, codified and slightly amended at Ohio Rev.
    Code Ann. § 1302.10(C) (West 2013), states:
    (continued...)
    -9-                                   6874
    was the FERC interest that Williams had proposed on October 18 and ConocoPhillips
    had objectively accepted on October 29. In the alternative, the superior court held that,
    if this court were to reverse summary judgment as to contract formation, Williams would
    be entitled to recovery in quantum meruit for the benefit to ConocoPhillips of the time-
    value of the $31 million prepayment, measured by the average market rate for
    commercial paper during the relevant period.
    The superior court granted Williams’s motion to enlarge time to file a
    motion for attorney’s fees and subsequently granted Williams full attorney’s fees and
    court costs as the prevailing party under the Dispute Resolution Agreement between
    Williams and ConocoPhillips.
    C.        Arguments On Appeal
    Both parties appeal. ConocoPhillips seeks reversal of summary judgment
    and entry of summary judgment in its own favor on a theory that no contract was formed
    for any interest rate. It also argues that no interest should be paid to Williams under a
    theory of quasi-contract or quantum meruit. Williams seeks reversal of the superior
    court’s order on reconsideration rescinding the initial summary judgment order as
    improvidently granted, arguing that a contract was formed under UCC §§ 2-207(1) & (2)
    as the superior court originally held. Williams also seeks reversal of the superior court’s
    5
    (...continued)
    (3)    Conduct by both parties which recognizes the
    existence of a contract is sufficient to establish a contract for
    sale although the writings of the parties do not otherwise
    establish a contract. In such case the terms of the particular
    contract consist of those terms on which the writings of the
    parties agree, together with any supplementary terms
    incorporated under any other provisions of this Act.
    -10-                                   6874
    alternative quantum meruit holding, arguing that it should receive FERC interest rather
    than commercial-paper interest awarded in quantum meruit.
    As to attorney’s fees and court costs, ConocoPhillips argues that the
    superior court abused its discretion by granting Williams’s motion to enlarge time to file
    a motion for attorney’s fees, by enlarging Williams’s time to file a cost bill with the
    Clerk of Court, and by granting full attorney’s fees and costs without reducing the award
    for various reasons.
    III.   STANDARD OF REVIEW
    We review rulings on motions for summary judgment de novo, “reading the
    record in the light most favorable to the non-moving party and making all reasonable
    inferences in its favor.”6 A party is entitled to summary judgment only if there is no
    genuine issue of material fact and if the party is entitled to judgment as a matter of law.7
    “A genuine issue of material fact exists where reasonable jurors could disagree on the
    resolution of a factual issue.”8 “Whether the evidence presented a genuine issue of
    material fact is a question of law that we independently review.”9 Determinations of

    A.	    UCC § 2-207 Applies To This Case To Determine Whether An
    Original Contract For Sale Of Oil Has Been Modified, And The
    Additional Requirements Of § 2-209 Regarding Modification Have
    Been Satisfied Or Waived.
    The parties vigorously dispute which article and sections of the UCC
    govern this case. We conclude that the superior court correctly held that Article 2 of the
    UCC and § 2-207 apply to this case, notwithstanding ConocoPhillips’s arguments that
    Article 9 or § 2-209 should govern to the exclusion of § 2-207.
    1.	    Article 2 of the UCC, rather than Article 9, applies to this case.
    ConocoPhillips and Williams disagree as to which article of the UCC
    applies in this case: Article 2, which governs “transactions in goods” but not “any

    transaction . . . intended to operate only as a security transaction,” 14 or Article 9, which
    governs transactions that “create[] a security interest in personal property or fixtures.”15
    ConocoPhillips argues that Article 9 should apply because the parties intended to “create
    an interest in the $31 million to secure Williams’[s] future payment obligations.”
    Williams argues that Article 2 should apply because the parties’ correspondence in
    October 2002 was a modification of the original Exchange Agreement for the sale of
    goods and the $31 million was a prepayment of a future obligation under that contract.16
    The superior court concluded that the $31 million was a prepayment as part
    of a contract modifying the original Exchange Agreement for a sale of goods and was
    thus covered by the provisions of Article 2. We agree.
    First, the superior court concluded that the parties intended the $31 million
    and subsequent agreement to constitute a “prepayment of an unliquidated account
    payable” rather than a security transaction. We agree and conclude that there is no
    genuine issue of material fact on this point. ConocoPhillips styled the payment as a
    “preliminary partial settlement” in its letter of October 29. ConocoPhillips now argues
    that it meant to indicate that the payment was a partial settlement of ConocoPhillips’s

    The parties vigorously dispute this preliminary issue because of their
    perception that Article 2 and Article 9 differ substantially in how they would apply to
    this case. ConocoPhillips argues that Article 9 imposes no duty to give credit for interest
    on cash collateral absent any actual interest earned and that any agreement for interest
    would have to be established under traditional common law rules of offer and
    acceptance. Williams seeks to benefit from the relaxed contract-formation provisions of
    § 2-207 to find a contract for FERC interest resulting from the October 2002
    correspondence. Because we hold in favor of Williams under § 2-207(1), we do not
    reach ConocoPhillips’s argument about the outcome of the case under Article 9.

    demands for an adequate security interest, but the record supports the superior court’s
    contrary conclusion. The October 29 letter refers to the payment as a preliminary partial
    settlement, not of ConocoPhillips’s demands for an adequate security interest, but rather
    of a dispute over the pricing provision of the Exchange Agreement with respect to
    retroactive Quality Bank adjustments.17 The course of negotiations provides further
    support for this view. ConocoPhillips’s first demand letter argued that Williams “now
    owes” ConocoPhillips $31 million under the Exchange Agreement’s pricing provision
    due to forthcoming Quality Bank adjustments that would be made retroactive. Williams
    disagreed, arguing in its letter of October 8 that the money was “not currently due” under
    the contract. It was this dispute over when the retroactive assessment charges would
    come due that the parties intended to settle with the wire transfer and subsequent
    agreement.    The superior court correctly interpreted the Exchange Agreement’s
    adequate-assurances provision, not as providing a right to demand security interests, but
    rather as “invit[ing] a negotiation between the parties regarding the nature and extent of
    additional consideration for the [continued] sale of goods” with a “contemplated outcome
    [of] a modification of the original sale contract such that the ground for insecurity be
    abated or ameliorated.” ConocoPhillips treated the adequate-assurances provision
    similarly in its initial demand letter of October 4 when it cited the adequate-assurances
    provision and then laid out a number of options for settling the dispute going beyond
    mere security interests, including making a cash payment, establishing a trust, providing
    a letter of credit, and providing a security interest.
    Second, as a matter of law, the Ohio courts have held that Article 2’s scope,
    covering “transactions in goods,” encompasses far more than just the original contract
    17
    Five years later, ConocoPhillips continued to view the $31 million payment
    as an “advance[],” at least in an internal email.

    for sale and also includes subsequent agreements to modify the original contract, such
    as by establishing new payment schedules.18 Thus, we conclude that the superior court
    correctly determined that, due to the parties’ intent to modify the original contract for the
    sale of goods, Article 2 would apply to the question of contract formation in this case.
    2.	    UCC § 2-207 applies to the contract modification in this case
    alongside the additional requirements of § 2-209.
    ConocoPhillips and Williams also disagree as to which specific sections of
    Article 2 of the UCC, if any, should apply in this case: § 2-209 to the exclusion of
    § 2-207, or § 2-209 in addition to § 2-207? We conclude that the superior court
    correctly held that § 2-209 should apply in addition to § 2-207, and we further conclude
    that the superior court correctly determined that the additional requirements of § 2-209
    have been satisfied in this case.
    As relevant here, UCC § 2-209, titled “Modification, Rescission and
    Waiver,” establishes several important rules governing modification of contracts within
    the scope of Article 2 of the UCC. First, § 2-209(1) abrogates the common law and
    specifies that “[a]n agreement modifying a contract within [Article 2 of the UCC] . . .
    needs no consideration to be binding.”19 Second, § 2-209(2) establishes that “[a] signed
    agreement which excludes modification or rescission except by a signed writing” is
    enforceable and that the agreement “cannot be otherwise modified or rescinded.”20

    sales contract for consumer goods after the buyer defaulted under the original payment
    plan).

    Finally, § 2-209(4) states that even if an attempted modification “does not satisfy the
    requirements of [subsection (2)] . . . it can operate as a waiver.”21
    As discussed in greater detail in section IV.B below, UCC § 2-207, titled
    “Additional Terms in Acceptance or Confirmation,” relaxes the common law mirror-
    image rule, which held that a contract could be formed only if the acceptance was a
    “mirror image” of the offer, replicating all of the terms of the offer without adding
    conflicting or additional terms.22 Instead of requiring a mirror-image acceptance,
    UCC § 2-207(1) permits contract formation whenever “[a] definite and seasonable
    expression of acceptance . . . is sent within a reasonable time . . . even though it states
    terms additional to or different from those offered or agreed upon, unless acceptance is
    expressly made conditional on assent to the additional or different terms.”23
    ConocoPhillips argues that, even if Article 2 of the UCC were to apply in
    this case, UCC § 2-209 should govern to the exclusion of the lenient contract-formation
    rules of § 2-207.24 ConocoPhillips reasons that § 2-207 addresses only initial contract
    formation and that any subsequent modification must satisfy § 2-209. ConocoPhillips

    Williams argues that ConocoPhillips failed to make this argument to the
    superior court and thus should not be able to raise it for the first time in this court. But
    a review of the record reveals that ConocoPhillips did argue to the superior court in its
    motion for reconsideration that “UCC 2-209 preempts UCC 2-207” and styled its
    arguments about UCC § 2-207’s application to this case in the alternative. Thus, the
    superior court was premature in stating in its order on motion for reconsideration that
    “Conoco and Williams now agree that UCC section 2-207 is applicable.” We conclude
    that ConocoPhillips did not waive its § 2-209 argument.
    -16-                                       6874
    contends modifications governed by § 2-209 can gain no help from § 2-207’s limited
    alterations of the common law because § 2-209 leaves untouched the common law
    mirror-image rule for agreements modifying a contract.25
    The superior court held that both § 2-209 and § 2-207 apply to the issue of
    contract modification in this case, and we agree. Precedent indicates that under Ohio
    law, § 2-207 applies to contract formation as well as subsequent contract modification.26
    Nor is Ohio alone in this conclusion; many other jurisdictions agree.27 The text of
    § 2-209 supports this conclusion. It does not purport to supplant any other provisions
    of Article 2; rather, it is best read as providing five additional rules that apply to
    modifications of preexisting contracts, supplementing other applicable rules elsewhere
    25
    ConocoPhillips presses this point because, in its view, § 2-209 and common
    law rules of acceptance would mean that “[e]ven if ConocoPhillips’[s] October 29 letter
    had assented to all terms of Williams’[s] October 18 letter except the FERC interest term,
    UCC § 2-209 would still require that the parties expressly assent to FERC interest.”
    Because we hold that § 2-207 applies to the contract modification in this case, we do not
    address what the outcome would be under common law rules of contract formation and
    modification.

    in the Code. Nothing in § 2-209 purports to restrict the application of § 2-207 to contract
    modifications, nor does anything in § 2-207 indicate that its scope should be restricted
    to initial contract formation to the exclusion of subsequent contract formations modifying
    the initial contract. Therefore, we conclude that § 2-207 may apply alongside § 2-209
    to modifications of a preexisting contract, at least under the facts presented in this case.28
    28
    ConocoPhillips cites no authority for the proposition that § 2-209 displaces
    § 2-207 and requires that all modifications of preexisting contracts satisfy the old
    common law mirror-image rule. Those cases that ConocoPhillips does cite do not
    address this issue but rather establish a distinct proposition: because all modifications
    (like all contracts) require mutual assent, unilateral modification of a preexisting contract
    is impossible and mere silence in the face of an offer to modify a contract is ineffective
    to convey acceptance of the offered modification. See U.S. Surgical 
    Corp., 5 F. Supp. 2d at 1206
    (when seller attached a label to the packaging of surgical equipment purporting
    to limit the customer to a single use of the equipment the buyer had already purchased
    pursuant to contract, no contract modification occurred simply by performing the original
    agreement and opening the package); Ariz. Retail Sys., 
    Inc., 831 F. Supp. at 764
    (when
    seller attached a shrink-wrap license to software packaging that buyer had already
    contracted to purchase, merely opening the package and continuing to perform the
    original contract did not function as a modification for lack of mutual assent); Wachter

    144 P.3d 747
    , 752-55 (Kan. 2006) (same); Jones
    v. Best, 
    950 P.2d 1
    , 5 (Wash. 1998) (when a realtor and seller of real property had a
    preexisting contract for realty services, the realtor’s proposed modification to his
    commission did not effect a modification because the seller’s silence to the proposal did
    not manifest mutual assent); Alaska Pac. Trading Co. v. Eagon Forest Prods., Inc., 
    933 P.2d 417
    , 420 (Wash. App. 1997) (when seller sent a proposal for modification of
    preexisting contract to buyer and buyer did not respond, no contract modification
    occurred because modification requires mutual assent). These cases do not establish
    what type of mutual assent is required to effectuate a contract modification — mirror-
    image acceptance as under the common law or something less as permitted by § 2­
    207(1). Accordingly, ConocoPhillips’s unsupported assertion that § 2-209 displaces § 2­
    207 with regard to contract modification does not affect our conclusion to the contrary,
    which is supported by the case law of Ohio and other jurisdictions as well as a
    commonsense reading of the statute.

    3.	   The additional requirement of § 2-209(2) for a signed writing to
    modify the Exchange Agreement was satisfied or waived.
    ConocoPhillips argues that even if § 2-207 applies in this case, no
    agreement could have been reached to modify the Exchange Agreement because the
    negotiations in October 2002 did not comply with the signed-writing requirement of the
    Exchange Contract as made enforceable by § 2-209(2). Section 2-209(2) states that “[a]
    signed agreement which excludes modification or rescission except by a signed writing
    cannot be otherwise modified or rescinded,”29 and the Exchange Agreement specifies
    that “[n]o changes, alterations, or modifications . . . of the Agreement shall be effective
    unless agreed to in writing by an authorized representative of the Parties.” The superior
    court concluded that the signed-writing requirement was satisfied in this case because
    “the parties communicated their offers by signed letters” or, in the alternative, because
    ConocoPhillips’s actions in accepting and retaining the $31 million and behaving “as if
    a contract had in fact been formed” constituted a waiver of the signed-writing
    requirement as permitted by § 2-209(4).30 We agree.
    ConocoPhillips argues that a signed writing within the meaning of § 2-209
    must include express assent to all proposed terms and that ConocoPhillips never
    explicitly agreed to FERC interest. But nothing in § 2-209 indicates that a signed writing
    must include express assent to all proposals, and we have already concluded that
    § 2-209’s requirements are additions to other Article 2 rules such as those in § 2-207.

    -19-	                                     6874
    The signed-writing requirement of § 2-209(2) is not a back-door route to reintroduce the
    common law requirements that are modified by § 2-207.
    ConocoPhillips also argues that its October 2002 correspondence could not
    be found to waive the signed-writing clause, citing Saydell v. Geppetto’s Pizza & Ribs
    Franchise Systems, Inc.31 But, as relevant here, that case indicates only that the delay of
    a franchisee in requesting the return of his franchise fee from the franchisor will not be
    held as a waiver of his right to recover the fee under the franchise contract at a later
    date.32 Moreover, that case rests on the common law of contract rather than the UCC.33
    We agree with ConocoPhillips that waiver under § 2-209(4) may be accomplished only
    through affirmative statements or actions indicating intent to waive and not merely by
    silence or inaction of ambiguous import, but we also agree with the superior court that
    ConocoPhillips’s actions and statements in this case could be construed as a matter of
    law only as indicating waiver of a signed-writing requirement. The following facts are
    decisive on this matter:     ConocoPhillips’s characterization of the payment as a
    “preliminary partial settlement” of the dispute over the Exchange Agreement’s pricing
    provision, ConocoPhillips’s use of the “received and retained” language mirroring the
    mode of acceptance laid down in Williams’s offer, and the entire course of conduct
    following these negotiations in which the parties indicated their belief that the deal was
    done and that they could move on to other matters.

    B.	    The Superior Court Did Not Err In Its Initial Grant of Summary
    Judgment to Williams Under UCC § 2-207(1) And Should Not Have
    Rescinded Its Order As Improvidently Granted.
    At common law, a contract could be formed only if the acceptance were a
    “mirror image” of the offer, replicating all of the terms of the offer without adding
    conflicting or additional terms.34 Bowing to the “modern realities of commerce” in
    which parties exchange non-mirroring writings and nonetheless proceed as if the deal is
    done, the UCC abrogated the mirror-image rule and replaced it with the provisions of
    UCC § 2-207.35 UCC § 2-207(1) permits contract formation whenever “[a] definite and
    seasonable expression of acceptance . . . is sent within a reasonable time . . . even though
    it states terms additional to or different from those offered or agreed upon, unless
    acceptance is expressly made conditional on assent to the additional or different terms.”36
    The purpose of UCC § 2-207(1) is to bring commercial practice and legal doctrine closer
    together: “Under this Article . . . a proposed deal which in commercial understanding
    has in fact been closed is recognized as a contract.”37
    When a contract is formed under UCC § 2-207(1), the terms of that contract
    generally include all of the offeror’s terms “which are not contradicted by the

    acceptance.”38 The “additional terms” found in the acceptance “are to be construed as
    proposals for addition to the contract.”39 UCC § 2-207(2) governs the conditions under
    which those proposals for additional terms become part of the contract: When the
    contracting parties are merchants,40 “the terms become part of the contract unless one of
    the following applies: (1) The offer expressly limits acceptance to the terms of the offer.
    (2) They materially alter it. (3) Notification of objection to them has already been given
    or is given within a reasonable time after notice of them is received.”41
    The superior court initially granted Williams’s motion for summary
    judgment on the grounds that ConocoPhillips’s letter of October 29 was a “definite and
    seasonable expression of acceptance” of the offer contained in Williams’s letter of
    October 18, within the meaning of UCC § 2-207(1), and that the contract that formed
    included a term for FERC interest.42 On reconsideration, the superior court concluded

    The superior court’s conclusion depended on six important facts, as
    summarized in its order on motion for reconsideration:
    1.    Contrary to Conoco’s litigation position,
    Conoco’s October 29 letter failed to state it was a rejection of
    and counteroffer to Williams’s October 18 offer.
    2.	    Conoco affirmatively indicated receipt and
    (continued...)
    -22-	                                     6874
    that “it should not have ruled summarily that Conoco’s letter of October 29, 2002 was
    a ‘definite and seasonable expression of acceptance,’ given Conoco’s express rejection
    of Williams’s joint-negotiating provision. The court’s characterization of Williams’s
    term as non-material constitutes a disputable inference, which defeats summary
    judgment.” We conclude that the superior court correctly granted summary judgment
    to Williams on the grounds that ConocoPhillips’s letter of October 29 was a definite and
    42
    (...continued)
    retention of the wire transfer, quoting Williams’s specified
    means of acceptance.
    3.     Conoco stated that while it did not agree with all
    of Williams’s proposed terms, no further negotiation was
    necessary.     It thereby reasonably communicated its
    acceptance of all but the explicitly rejected joint-negotiation
    provision in the Williams counteroffer.
    4.      Conoco explicitly stated that it “received and
    retained the payment as a preliminary partial settlement” of
    Williams’s contingent liability in the FERC proceeding. By
    this rhetoric, Conoco suggested that the matter was settled.
    This would only occur if Conoco accepted Williams’s
    counteroffer.
    5.     Conoco stated no objection to Williams’s
    interest provision. Conoco had previously proposed that the
    payment would accrue interest in its initial offer on
    October 17.
    6.     Conoco closed its letter by indicating
    satisfaction with Williams’s proffered assurance and agreeing
    to continue to honor the exchange agreement, thereby lifting
    its threat to cease deliveries of crude oil to Williams’s
    refinery. This language is inconsistent with a call for further
    negotiation.
    -23-                                  6874
    seasonable expression of acceptance under § 2-207(1), and that its order on
    reconsideration was an understandable error resulting from an overabundance of caution.
    1.	    Under UCC § 2-207(1), ConocoPhillips’s reply letter of
    October 29 was a definite and seasonable acceptance leading to
    contract formation.
    The superior court correctly held in its grant of summary judgment that
    ConocoPhillips’s letter of October 29 43 was a “definite and seasonable expression of
    acceptance” of the offer made in Williams’s letter of October 18, within the meaning of
    UCC § 2-207(1). In that letter, ConocoPhillips acknowledged that it had “received and
    retained the Payment as a preliminary partial settlement” of the disagreement over the
    pricing provision of the oil exchange contract, mirroring the language Williams used in
    its letter of October 18 specifying the mode of acceptance of its offer:
    “ConocoPhillips’[s] receipt and retention of the [money] . . . shall constitute
    ConocoPhillips’[s] agreement with the terms set forth in . . . this letter.” ConocoPhillips
    did not state that its letter was a rejection of and counteroffer to Williams’s offer of
    October 18 but rather indicated that the dispute over the pricing provision of the
    Exchange Agreement was now settled and that no further negotiation was necessary to
    close the deal. ConocoPhillips agreed to continue to honor the Exchange Agreement,
    43
    We note that ConocoPhillips also sent a reply email on October 18
    following receipt of the wire transfer and Williams’s letter specifying the terms of the
    offer, in which ConocoPhillips acknowledged receipt and concluded that it could “now
    focus [its] efforts on getting [the FERC rate-making case] settled.” We do not reach the
    issue of which reply led to contract formation under § 2-207(1): the email of October 18
    or the subsequent letter of October 29. We follow the influential and persuasive
    authority of other jurisdictions in deciding that “[w]e see no need to parse the parties’s
    [sic] various actions to decide exactly when the parties formed a contract” under
    § 2-207(1). Step-Saver Data Sys., Inc. v. Wyse Tech., 
    939 F.2d 91
    , 98 (3d Cir. 1991).
    Rather, the content of both documents informs the analysis and drives our conclusion
    that a contract was formed under § 2-207(1).

    thus lifting the threat to halt crude oil deliveries and indicating satisfaction with
    Williams’s assurance. Finally, ConocoPhillips closed the letter by indicating that the
    matter was settled and the parties could move on with their regular business:
    “ConocoPhillips looks forward to continuing to work with Williams under the parties’
    various agreements.”44 All of these facts indicate that ConocoPhillips gave Williams a
    definite and seasonable expression of acceptance of its offer of October 18.
    Our conclusion is not altered by the fact that ConocoPhillips’s letter of
    October 29 seemed to object to the joint-negotiating provision,45 as well as vaguely hint
    that “ConocoPhillips does not agree with all of the terms stated in your letter.” The
    44
    That ConocoPhillips considered the matter settled as per the October 18
    letter is further supported by an email sent from ConocoPhillips to Williams on
    October 18: “We received your letter and our treasury guys just confirmed receipt of the
    funds. We can now focus our efforts on getting [the] Quality Bank [rate-making case]
    settled.”
    45
    For the purposes of this analysis, we assume arguendo that ConocoPhillips
    actually rejected Williams’s joint-negotiating term. However, on this record, that is far
    from certain. Williams had offered as a term in its letter of October 18 that
    “ConocoPhillips agrees that it will continue good faith efforts to resolve all Quality Bank
    issues through negotiated settlement and vigorous support of the Eight-Party Joint
    Defense Position before FERC and the RCA.” In its reply letter of October 29,
    ConocoPhillips stated that it “is continuing ‘good faith efforts to resolve all Quality Bank
    issues through negotiated settlement and vigorous support for the Eight-Party Joint
    Defense Position before FERC and the RCA,’ ” but it insisted that this obligation was
    “[c]ompletely independent of the Payment” and that “[t]here is no linkage whatsoever”
    between ConocoPhillips demanding adequate assurances and the joint-negotiating
    position in the rate-making case. We note that the superior court concluded that
    ConocoPhillips “rejected” the joint-negotiating term and are mindful of the need to make
    all reasonable inferences in favor of the non-moving party when considering a grant of
    summary judgment. Witt v. State, Dep’t of Corr., 
    75 P.3d 1030
    , 1033 (Alaska 2003).
    But we note that if the best view of the facts were that ConocoPhillips did not reject the
    joint-negotiating provision, our conclusion about contract formation under § 2-207(1)
    would be even stronger.
    -25-                                       6874
    UCC makes clear that a “definite and seasonable expression of acceptance” results in
    contract formation “even though it states terms additional to or different from those
    offered.”46 Indeed, the entire purpose of UCC § 2-207(1) was to abrogate the common
    law mirror-image rule and allow for non-mirroring acceptances to nonetheless result in
    contract formation.47
    To be sure, there is an outer limit to how much a return letter may differ
    from an offer and still result in contract formation under § 2-207(1), and the contours of
    that limit are not entirely clear from the Code, the case law, or treatises. UCC § 2-207(2)
    presupposes that a return document can be an acceptance under § 2-207(1) even though
    it includes additional terms that “materially alter[]” the offer,48 and a respected treatise
    concludes that “it is clear that a document may be an acceptance . . . and yet differ
    substantially from the offer.”49 A Court of Appeals in Ohio has held in Alliance Wall
    Corp. v. Ampat Midwest Corp. that a return letter does not constitute an acceptance under
    § 2-207(1) “where the parties disagree as to ‘dickered for’ terms.”50 The court did not

    UCC § 2-207(2) governs when additional, non-mirroring terms from a
    return letter constituting an acceptance under § 2-207(1) will become part of the contract
    thus formed. UCC § 2-207(2)(b) indicates that, among merchants, non-mirroring terms
    automatically become part of the contract unless those terms “materially alter” the
    contract formed under § 2-207(1). See also 1 W HITE , SUMMERS & H ILLMAN , supra

    contract forms when a purchase order requests a certain amount of a commodity at $0.10
    per pound and the acknowledgment proposes $0.15 per pound.51 Another example
    comes from Alliance Wall itself, where the court concluded that no contract formed
    under § 2-207(1) when time was of the essence, the parties did not reach agreement on
    a delivery date, the delivery date was of utmost importance to each party, and the return
    document struck the offeror’s delivery date and inserted its own.52 We conclude based
    on these authorities that, whatever the precise boundaries of the dickered-for exception
    to § 2-207(1) acceptance, the return document will qualify for that exception only if it
    differs significantly (not just materially) from the offer on a sufficiently important term.53

    . In that particular case, the delivery date appears to
    have been a crucial and hotly disputed term throughout negotiations. Indeed, the
    delivery date “appears to have been more important to the buyer than was the exact
    price” and “[t]he seller appeared to be just as adamant not to be bound to any particular
    date.” 
    Id. 53 The
    parties offer competing interpretations of the scope of the dickered-for
    exception, both of which we reject.
    Williams argues that a dickered-for term is one which is “both material and
    . . . previously negotiated between the parties” and that the joint-negotiating provision
    cannot qualify because it was not negotiated prior to the October 18 letter. Not only does
    Williams not cite any authority for this proposition, but it also conflicts with the
    established example of a dickered-for term in the Alliance Wall case, where the court
    cited as an example of a dickered-for term a price change that had not previously been
    disputed by the parties.

    -27-                                        6874
    ConocoPhillips’s letter of October 29 is clearly outside of those bounds and
    results in contract formation under § 2-207(1). First, the joint-negotiating provision was
    not sufficiently important in the context of the overall transaction to stymie § 2-207(1)
    contract formation. Unlike the delivery date in Alliance Wall, the joint-negotiating
    provision was not of utmost importance to the parties in this case, subjectively or
    objectively: From an objective perspective, it would be difficult to conclude that a term
    merely purporting to reaffirm ConocoPhillips’s commitment to a preexisting joint-
    negotiating agreement is important in the context of the overall settlement. Indeed, the
    53
    (...continued)
    ConocoPhillips argues that dickered-for terms are defined in opposition to
    “standard boiler-plate terms” and encompass all those terms “that are unique to each
    transaction such as price, quality, quantity, or delivery terms as compared to the usual
    unbargained terms on the reverse side [of a form] concerning remedies, arbitration, and
    the like[.]” (Alterations in original.) ConocoPhillips argues that “[i]n this case, all of the
    terms in the parties’ correspondence were ‘dickered for’ terms.” (Emphasis in original.)
    But a distinction between front-side terms and reverse-side or boilerplate terms is not
    useful in this context, where the parties have negotiated every provision of the contract
    rather than engaging in a traditional battle of the forms. Under ConocoPhillips’s theory,
    § 2-207(1) has no application outside of the boilerplate context. Yet nothing in the text
    of § 2-207 would limit itself in such a way, and courts have often applied § 2-207 in
    situations not involving boilerplate forms but rather detailed negotiation among
    sophisticated parties, on the theory that § 2-207 applies whenever an acceptance does not
    mirror an offer. See, e.g., Energy Mktg. Servs., Inc. v. Homer Laughlin China Co., 
    186 F.R.D. 369
    (S.D. Ohio 1999) (stating that, as a matter of Ohio contract law,
    UCC § 2-207(1) applies “when an acceptance differs in terms from an offer,” 
    id. at 374,
    including where the parties had negotiated a contract amendment over the course of
    years, 
    id. at 371-73),
    aff’d, 
    229 F.3d 1151
    (6th Cir. 2000). We reject any interpretation
    of the dickered-for terms exception that would swallow the more general § 2-207(1) rule
    and bring common law rules in through the back door.
    Accordingly, we reject both parties’ proffered definitions of the scope of
    the dickered-for terms exception in favor of our formulation here of the outer bounds of
    the exception, whatever its precise definition.
    -28-                                        6874
    relative unimportance of this provision may explain why the parties indicate little
    subjective interest in the provision. The joint-negotiating term was first introduced into
    negotiations in Williams’s letter of October 18. That the parties considered this
    provision to be relatively unimportant is confirmed by the parties’ actions indicating that,
    in their minds, the deal was done following acceptance of the payment notwithstanding
    ConocoPhillips’s objections.54 Second, the degree of change to the contested term
    proposed by the October 29 acceptance is also relatively small. Unlike the 50% increase
    in price in the treatise hypothetical cited in Alliance Wall, there is relatively little distance
    between the offer to reinscribe a preexisting, independent agreement and the return
    proposal to voluntarily commit to continue performing a preexisting, independent
    agreement.
    Simply put, ConocoPhillips’s rejection of Williams’s joint-negotiating
    provision was a relatively unimportant and relatively small discrepancy within the
    context of the larger deal. The course of negotiation and the parties’ post-negotiation
    behavior indicate that neither party thought the term sufficiently important or the change
    sufficiently great to require additional negotiation.55 In short, the parties thought they
    54
    The superior court concluded that “Conoco accepted the proffered $31
    million and behaved as if a contract had in fact been formed.”
    55
    In addition to ConocoPhillips’s purported rejection of the joint-negotiating
    provision, ConocoPhillips also stated in its letter of October 29 that it “d[id] not agree
    with all of the terms stated in [Williams’s] letter” but that it “also d[id] not believe it
    would prove productive to conduct a letter writing campaign as to what the Payment
    represents or specific terms and conditions associated with the Payment.” In the words
    of the superior court in its order on motion for summary judgment, such “seemingly
    studied ambiguity” hinting at “undisclosed issues with at least one term of Williams’[s]
    counteroffer” cannot preclude the conclusion that there was a definite and seasonable
    expression of acceptance in this case. As the superior court properly concluded, “If
    Conoco perceived no need to further discuss the terms Williams proposed, but elected
    (continued...)
    -29-                                         6874
    were done negotiating, and the purpose of § 2-207(1) is to step in to supply a contract
    in just such a situation.
    Finally, ConocoPhillips garners no help from § 2-207(1)’s narrow
    exception for acceptances “expressly made conditional on assent to the additional or
    different terms.” That exception “has been construed narrowly” by courts56 to apply
    “only to an acceptance which clearly reveals that the offeree is unwilling to proceed with
    the transaction unless he is assured of the offeror’s assent to the additional or different
    terms therein.”57 Here, ConocoPhillips failed to state explicitly in its letter of October 29
    55
    (...continued)
    to retain the $31 million, the reasonable implication is that Conoco grudgingly but
    definitively assented to the Williams terms, except those explicitly rejected.” Vague
    hints of disagreement combined with acceptance of payment in the form prescribed by
    the offer and explicit disagreement with one term cannot be allowed to convert an
    otherwise-definite expression of acceptance into an ineffective counteroffer. To hold to
    the contrary would be to undermine the guiding principle of interpretation of
    UCC § 2-207: preventing one party from obtaining an “unearned advantage.” See
    1 W HITE , SUMMERS & H ILLMAN , supra note 22, § 2:9, at 81. In order for objections in
    a return letter to foreclose contract formation under § 2-207(1), those objections must be
    sufficiently explicit as to which provisions they pertain to, or sufficiently clear as to the
    respondent’s intent to reject the offer in general. See 
    id. § 2:11,
    at 89 (arguing that
    silence in a § 2-207(1) acceptance as to a term in the offer constitutes grudging
    acceptance of that term); 
    id. at 89
    n.1 (collecting cases). Here, ConocoPhillips never
    characterized its letter of October 29 as a rejection in general, and the only specific term
    it registered disagreement with was the joint-negotiating provision. Accordingly, its
    exercise in studied ambiguity cannot succeed where its more specific objections failed.
    As the superior court correctly concluded, “Conoco grudgingly but definitively assented
    to the Williams terms, except those explicitly rejected.”

    that its acceptance was conditioned on Williams’s assent to the omission of the joint-
    negotiating provision from the contract. ConocoPhillips instead appeared eager to
    proceed with the transaction as concluded and move on to address other issues. As
    ConocoPhillips told Williams in an email after receiving the $31 million transfer, “We
    can now focus our efforts on getting [the Quality Bank rate-making case] settled.”
    Accordingly, we conclude that the superior court’s initial grant of summary
    judgment in favor of Williams under UCC § 2-207(1) was proper.
    2.	    The terms of the resulting contract included a provision to
    credit the $31 million prepayment with interest at the FERC
    rate.
    When a contract is formed under UCC § 2-207(1), the terms of that contract
    generally include all of the offeror’s terms “which are not contradicted by the
    acceptance.”58 We have previously held that an offeree’s failure to “manifest any
    objection to the terms” of an offer or to “mak[e] its acceptance of the offer conditional
    on [the offeror’s] assent to different terms” results in the offeror’s terms “be[coming] part
    of the contract.”59 This position is amply supported by persuasive authority in other
    jurisdictions.60 It is true that in response to an entire offer, mere silence or inaction

    abrogating the mirror-image rule of the common law: If non-mirroring acceptances were
    construed too liberally as being conditioned on the assent of the offeror, the rigidity of
    the mirror-image rule would re-enter the Code through the back door of an exception to
    § 2-207(1).

    generally do not indicate assent.61 But silence as to one term, coupled with assent to the
    offer as a whole, cannot defeat inclusion of that term in the resulting contract.
    The superior court’s order on summary judgment correctly concluded that,
    on the facts of this case, ConocoPhillips’s acceptance of October 29 formed a contract
    under § 2-207(1), the terms of which included a provision to credit Williams with
    interest on the $31 million principal prepayment at the rate prescribed by the FERC.
    ConocoPhillips’s letter of October 29 was a definite and seasonable expression of
    acceptance resulting in contract formation. ConocoPhillips indicated that no further
    negotiation was necessary, thereby communicating acceptance of all but the explicitly
    rejected terms. ConocoPhillips did not object to Williams’s provision specifying that the
    principal would accrue interest at the FERC rate but rather objected only to the joint-
    negotiating provision.     Moreover, ConocoPhillips had already proposed that the
    prepayment would accrue interest (at the LIBOR rate) on October 17, so as a matter of
    law its silence as to Williams’s counteroffer of October 18 for FERC interest constitutes
    assent to Williams’s proposal. Finally, as the superior court correctly noted, “[t]he
    demand for FERC interest was not an implausible overreach” but rather was a reasonable
    proposal in light of the deal, such that its inclusion in the resulting contract is proper.62

    -32-                                       6874
    We conclude that the contract formed by ConocoPhillips’s acceptance includes a term
    for FERC interest.
    3.	    The superior court was correct in its first entry of summary
    judgment, and thus it should not have rescinded its initial order
    as improvidently granted.
    After granting Williams’s motion for summary judgment and concluding
    that a contract for FERC interest was formed under § 2-207(1), the superior court granted
    ConocoPhillips’s motion for reconsideration and ordered additional briefing on the
    UCC § 2-207 issues because the parties had not briefed them before. ConocoPhillips
    62
    (...continued)
    interest at the administratively prescribed FERC rate rather than the “market rate” of
    LIBOR. ConocoPhillips argues that LIBOR is inherently fair because “[h]ad the parties
    proceeded on this basis, neither party would have gained or lost value” because
    “Williams would have lost the time value of its $31 million, but it would have received
    interest at a market rate from ConocoPhillips to make up for that time value loss.”
    ConocoPhillips confuses the issue by hypothesizing a single market rate of interest and
    thus attempts to make Williams’s demand for FERC interest seem unreasonable. But it
    is axiomatic that there is no single “market rate” of interest; rather, market rates of return
    depend on which market the investor chooses to enter and the concomitant risk the
    investor chooses to assume. See, e.g., Edwin J. Elton & Martin J. Gruber, Modern
    Portfolio Theory, 1950 to Date, 21 J. BANKING & FIN . 1743, 1744 (1997). If Williams
    knew it would be responsible for the higher FERC interest rate on retroactively assessed
    Quality Bank degradation charges, then it would be reasonable for Williams to attempt
    to earn FERC rates of interest on the principal it set aside for such charges by purchasing
    assets in a market with correspondingly high levels of risk and return. Accordingly, it
    might be reasonable for Williams to insist when it transferred ownership of the principal
    corpus to ConocoPhillips that ConocoPhillips agree to credit Williams with the FERC
    rate of interest Williams would have otherwise attempted to earn for itself. Indeed, in
    oral argument, counsel for Williams stated that this was precisely the rationale behind
    Williams’s proposal for FERC interest. Thus, LIBOR interest is not the only “ ‘break
    even’ point” in the transaction, ConocoPhillips’s assertions to the contrary
    notwithstanding. Rather, the prospective time-value of money is an endogenous variable
    susceptible to influence by the actions of the person making investment decisions.
    -33-	                                       6874
    argued: (1) its letter of October 29 was not a definite and seasonable expression of
    acceptance within the meaning of § 2-207(1); (2) a contract under § 2-207(3) was formed
    in the course of performance but only for retention of the transferred money; (3) no
    agreement was reached for interest; and (4) the gap-filling interest provision of
    UCC § 9-207(3), which does not mandate accrual of interest on cash collateral obtained
    in a security transaction, governs this case. Williams supported the original grant of
    summary judgment.
    On reconsideration, the court concluded that it had improvidently granted
    summary judgment because “it should not have ruled summarily that Conoco’s letter of
    October 29, 2002 was a ‘definite and seasonable expression of acceptance,’ given
    Conoco’s express rejection of Williams’s joint-negotiating provision. The court’s
    characterization of Williams’s term as non-material constitutes a disputable inference,
    which defeats summary judgment.”63
    We conclude that the superior court correctly granted Williams summary
    judgment the first time around and erred in concluding on reconsideration that it had
    63
    As an additional reason favoring its reconsideration of the grant of
    summary judgment, the superior court stated that its “characterization of Conoco’s
    rejection of the joint-negotiating term . . . fits awkwardly within the actual wording of
    UCC section 2-207(B) [sic], which speaks of additional terms being construed as
    ‘proposals for addition to the contract.’ ” (Emphasis in original.) The superior court’s
    concerns were inapposite to the question before the court. UCC § 2-207(1) and (2)
    address two distinct issues: (1) addresses the issue of contract formation, while
    (2) addresses the issue of which additional terms from the non-mirroring acceptance
    come into the new contract. The § 2-207(2) question in this case — whether
    ConocoPhillips’s apparent rejection of the joint-negotiating provision would cause that
    provision to fall out of the contract formed under § 2-207(1) or whether, in the
    alternative, the rejection of a term in the offer cannot be effective under § 2-207(2)
    because that section addresses only “additional” terms — has no bearing on the
    § 2-207(1) question in this case — whether the October 29 letter constitutes a definite
    expression of acceptance of Williams’s October 18 offer.
    -34-                                     6874
    improvidently granted summary judgment.64 As we have already noted, the superior
    court’s error was understandable, resulting from an abundance of caution. This is a
    complex case. But as we concluded in section IV.B.1 above, ConocoPhillips’s rejection
    of Williams’s joint-negotiating provision was neither a sufficiently large change in that
    provision nor a sufficiently important part of the overall bargain to vitiate contract
    formation under § 2-207(1). That conclusion of law is not a disputable inference of fact
    that could foreclose summary judgment.65 Indeed, the parties do not dispute any material
    issues of fact, as the superior court correctly noted in its initial order granting Williams
    summary judgment. The only remaining disputes were about the legal conclusions to be
    drawn from those facts. Accordingly, we hold that the superior court’s order rescinding
    summary judgment as improvidently granted was error. We reverse that order and affirm
    the initial order granting summary judgment on the basis of UCC § 2-207(1).66
    64
    Because we conclude that a contract for FERC interest was created in
    October 2002 under UCC § 2-207(1), we decline to reach other issues raised on appeal,
    including whether a contract for FERC interest was reached under § 2-207(3) and
    whether or at what rate Williams is owed interest on a theory of quantum meruit.
    65
    To the extent that the superior court was under the impression that a reply
    letter containing a mere “material” change to the contract could prevent contract
    formation under § 2-207(1), the court erred. UCC § 2-207(2)’s provisions governing
    which non-mirroring terms enter a contract formed under § 2-207(1) make clear that a
    materially different term in the reply letter can nonetheless result in contract formation.
    See O HIO REV . CODE A NN . § 1302.10(B)(2) (West 2013) (codifying U.C.C.
    § 2-207(2)(b)) (stating that, when the parties to a contract formed by acceptance under
    § 2-207(1) are merchants, non-mirroring terms in an acceptance do not automatically
    become part of the resulting contract where those terms “materially alter” the offer).

    C.	    The Superior Court Did Not Abuse Its Discretion By Granting
    Attorney’s Fees And Court Costs To Williams.
    ConocoPhillips and Williams agreed in a Dispute Resolution Agreement
    at the outset of litigation in 2007 that the “prevailing Party . . . shall be entitled to recover
    reasonable attorney fees and court costs” to be “paid within twenty (20) days after receipt
    of an invoice for such costs containing documentation reasonably supporting the
    amounts.” Both parties agree that Williams is the prevailing party in this litigation
    because Williams “obtained the relief it sought.” But ConocoPhillips argues that the
    superior court abused its discretion by granting Williams’s motion for leave to enlarge
    time to file a motion for attorney’s fees, extending the time to file a cost bill with the
    Clerk of Court, and awarding full attorney’s fees to Williams while rejecting
    ConocoPhillips’s suggested reductions. We affirm the superior court’s actions with
    regard to attorney’s fees and court costs in all respects.

    (citing W.
    Pioneer, Inc. v. Harbor Enters., Inc., 
    818 P.2d 654
    , 658 (Alaska 1991)). But the
    situation before the court today is entirely different. Rather than seeking to roll back the
    tape to summary judgment after having proceeded through trial to resolve disputed facts,
    Williams seeks merely to roll back the tape to the initial grant of summary judgment
    under § 2-207(1) after we find that the order on reconsideration was error as a matter of
    law. Neither Larson nor any other precedent of this court prevents us from reviewing
    a prior motion for summary judgment in this procedural context. Indeed, Larson and
    Western Pioneer support the proposition that review in this context is proper because the
    error in the order on reconsideration was a legal error.

    1.	    The superior court did not abuse its discretion by granting
    Williams additional time to file its motion for attorney’s fees.
    Under Alaska Civil Rule 82, in order to recover an “award of attorney’s
    fees . . . pursuant to contract,” the prevailing party must file a motion “within 10 days
    after the date shown in the clerk’s certificate of distribution on the judgment” or within
    “such additional time as the court may allow.”67 Failure to file a timely motion “shall be
    construed as a waiver of the party’s right to recover attorney’s fees.”68 Alaska Civil
    Rule 6(b) further specifies that, where the Alaska Civil Rules require an act “be done at
    or within a specified time, the court for cause shown may at any time in its discretion . . .
    upon motion made after the expiration of the specified period permit the act to be done
    where the failure to act was the result of excusable neglect.”69 Finally, Alaska Civil
    Rule 94 provides that the Civil Rules “are designed to facilitate business and advance
    justice” and they “may be relaxed or dispensed with by the court in any case where it
    shall be manifest to the court that a strict adherence to them will work injustice.”70
    In this case, the clerk’s certificate of distribution on the final judgment
    shows the date February 9, 2012, and the ten-day period for Williams to file a motion for
    costs and attorney’s fees ended on February 20 or 22, 2012.71 Williams did not file

    The parties disagree as to when the ten-day clock ran in this case. Williams
    argues that it filed its motion to enlarge time to file a motion for attorney’s fees “eight
    days after it was due” on March 1, implying that the clock would have run on
    February 22. (2012 was a leap year.) ConocoPhillips argues that Williams’s motion was
    (continued...)
    -37-	                                      6874
    within that period. On March 1 Williams filed a motion for leave to enlarge time to file
    a motion for attorney’s fees, asking the court to accept an attached motion for
    $469,331.68 in attorney’s fees and several exhibits. Williams argued that its failure to
    meet the ten-day deadline was the result of excusable neglect under Rule 6(b) because
    it did not know that Rule 82’s requirements would apply to its motion for attorney’s fees
    under the Dispute Resolution Agreement. Williams further argued that the delay “does
    not impact the judicial proceedings in this case and it does not prejudice
    ConocoPhillips.” ConocoPhillips argued that an attorney’s mistake as to the applicable
    rules in this context cannot constitute excusable neglect.
    The superior court granted Williams’s motion to enlarge time to file a
    motion for attorney’s fees, finding “excusable neglect and no prejudice.” The superior
    court explained that “[t]he court was inartful” in its Final Judgment, in which the court
    stated that “Williams may move the Court for an award of attorney fees” as the
    “prevailing party . . . pursuant to . . . the parties’ Dispute Resolution Agreement.” The
    superior court explained that it “should also have struck the ‘pursuant to’ . . . clause,
    because the attorney fee entitlement is pursuant to ARCP 82.”
    On appeal, ConocoPhillips argues that the superior court abused its
    discretion when it “took the blame for Williams’[s] failure to timely file its motion.”
    ConocoPhillips reasoned that there was no excusable neglect for the late motion because
    Rule 82(c)’s applicability to contract-based fee motions was clear on the face of the Rule
    and that nothing in the superior court’s final judgment created ambiguity on that issue.

    due by Monday, February 20, 2012 and that its motion was ten days late. Neither party
    adequately explains the legal theory underlying these assertions. But we conclude that
    the two-day difference between being late by eight days (Williams’s theory) and being
    late by ten days (ConocoPhillips’s theory) would not change the outcome of our holding
    in this case.
    -38-                                      6874
    ConocoPhillips also reasoned that the mere lack of prejudice to ConocoPhillips alone
    cannot sustain a finding of excusable neglect. We review a trial court’s disposition of
    a motion to enlarge time for abuse of discretion.72
    We affirm the superior court’s order granting Williams’s motion to enlarge
    time to file a motion for attorney’s fees. The superior court certainly did not abuse its
    discretion in this case. The delay of ten days in this case is well within the zone of
    permissible discretion suggested by our precedent. In T & G Aviation, Inc. v. Footh,73
    we held that the superior court did not abuse its discretion by allowing a party to file a
    motion for attorney’s fees 70 days late, even in the absence of a persuasive explanation
    for the delay.74 Indeed, when there is no showing of prejudice, it may be an abuse of
    discretion not to allow an untimely motion for attorney’s fees on facts such as those
    presented in this case.75   In short, Williams’s neglect in failing to recognize the
    applicability of Rule 82(c)’s deadlines is “that type of excusable inadvertence or neglect

    did not abuse its discretion by granting Williams’s motion to enlarge time to file a
    motion for attorney’s fees.
    2.	    The superior court did not abuse its discretion by granting
    Williams additional time to file its motion for court costs.
    Alaska Civil Rule 79(b) requires77 a prevailing party seeking to recover
    costs to “file and serve an itemized and verified cost bill, showing the date costs were
    incurred, within 10 days after the date shown in the clerk’s certificate of distribution on
    the judgment . . . or such additional time as the court may allow.” The rule further
    specifies that “[f]ailure of a party to file and serve a cost bill . . . will be construed as a
    waiver of the party’s right to recover costs.”78 Just as discussed previously with regard
    to Rule 82(c) motions for attorney’s fees, Rules 6(b) and 94 provide further discretionary

    77
    We assume without deciding that Civil Rule 79(b) applies in this case, even
    though court costs were sought pursuant to contractual entitlement rather than Rule 79
    itself. ConocoPhillips and Williams both couch their arguments as if Rule 79(b)
    provided the relevant deadlines for filing a cost bill. But we note sua sponte that
    Rule 79(b), unlike Rule 82(c), does not purport to require a cost bill filing for an award
    of court costs “under this rule or pursuant to contract.” Alaska R. Civ. P. 82(c). Rather
    than purporting to apply specifically to contract-based awards of court costs, Rule 79(b)
    states flatly that “[t]o recover costs, the prevailing party must file and serve an itemized
    and verified cost bill . . . within 10 days.” Alaska R. Civ. P. 79(b). Whether Rule 79
    applies to contractual court-cost awards, or whether its rules should apply only by
    analogy or by the adoption and stipulation of the parties, we leave for another day when
    that issue is presented to the court squarely. We hold today that, even if Rule 79’s
    requirements apply in full force in this case, the superior court did not abuse its
    discretion in granting leave to Williams to file its cost bill late.

    flexibility on a showing of excusable neglect or when a strict adherence to the ten-day
    limit would “work injustice.”79
    Eight to ten days after it would have been due under Rule 79(b)’s ten-day
    period,80 Williams filed a motion for leave to enlarge the time to file its motion for
    attorney’s fees on March 1, 2012. Although this motion did not mention Civil Rule 79
    by name, it clearly indicated that Williams was seeking compensation for court costs.
    Specifically, that motion mentioned the difficulty Williams experienced assessing fees
    and costs; included a costs calculation of $10,489.05 as an exhibit attached to the motion;
    included a section for the clerk’s ruling on the cost bill and a separate line for
    “recoverable costs” of $10,489.05 in the attached motion for attorney’s fees; and it
    concluded the motion for attorney’s fees by asking for “$479,819.73 as reasonable
    attorney fees and court costs.” ConocoPhillips argued that Williams had waived any
    right to costs because “[c]ost bills are considered by the clerk pursuant to a separate
    procedure, . . . and Williams may not ‘piggyback’ an untimely cost bill onto its attempt
    to file an untimely fee motion.” The superior court granted Williams’s motion for leave
    to enlarge time to file a motion for attorney’s fees and also “deemed filed” the motion
    for attorney’s fees as well as “exhibits supporting [Williams’s motion for attorney’s
    fees],” which included the cost bill.
    79
    Rule 6(b) provides that, where the Alaska Civil Rules require an act “be
    done at or within a specified time, the court for cause shown may at any time in its
    discretion . . . upon motion made after the expiration of the specified period permit the
    act to be done where the failure to act was the result of excusable neglect.” Alaska R.
    Civ. P. 6(b). Rule 94 provides that the Civil Rules “are designed to facilitate business
    and advance justice” and they “may be relaxed or dispensed with by the court in any case
    where it shall be manifest to the court that a strict adherence to them will work injustice.”

    Six months later, and eight months following the expiration of the ten-day
    period under Rule 79, the superior court ruled on Williams’s motion for attorney’s fees
    and awarded Williams full attorney’s fees. In that order, the court also noted that
    “Williams should submit its cost bill to the Clerk of Court for a reasonableness review.”
    ConocoPhillips objected that “[t]his sua sponte grant of an 8-month extension of time
    was improper” because Williams had never requested it and because Williams did not
    show excusable neglect. The Clerk of Court granted $6,441.70 in court costs to
    Williams, and the superior court rejected ConocoPhillips’s motion for review of cost
    award. The superior court’s final judgment on attorney’s fees and costs included
    $6,441.70 of court costs.
    ConocoPhillips argues that the superior court abused its discretion when it
    granted Williams an extension of time to file its cost bill. ConocoPhillips reasons that
    Rule 6(b) allows extension after the time period lapses only “ ‘upon motion’ establishing
    that ‘the failure to act was the result of excusable neglect.’ ” Under its view, neither
    condition was met here because the court awarded an extension sua sponte and because
    there was no showing of excusable neglect for such a long delay. Williams argues that
    it sought an extension of the Rule 79 deadline by including costs in its motion for leave
    to enlarge time to file a motion for attorney’s fees and that this same motion showed
    excusable neglect. It argues that the superior court “deemed filed” its cost bill, as an
    attached exhibit, when it granted its motion for leave to enlarge time for filing a motion
    for attorney’s fees, and that the court’s subsequent invitation to file its cost bill with the
    Clerk of Court was within the court’s discretionary authority.
    -42-                                        6874
    We conclude that the superior court did not abuse its discretion in granting
    Williams leave to file a late cost bill with the Clerk of Court. In Vazquez v. Campbell,81
    we confronted a situation in which the prevailing plaintiff timely filed a sufficiently
    detailed cost bill, not as a cost bill presented to the Clerk of Court as required by
    Rule 79(b), but rather as a motion to the superior court.82 We held that the prevailing
    party had “substantially complied with the requirements of rule 79” because “[i]f the
    superior court had wished, it could have referred the question of costs to the clerk for an
    initial decision.”83 Unlike in Vazquez, Williams did not timely file its motion for court
    costs under Rule 79(b) (instead, it filed its cost bill with the Clerk of Court eight months
    late), and it is unclear on this record whether its cost accounting associated with its
    motion for leave to enlarge time to file a motion for attorney’s fees was sufficiently
    detailed to meet the requirements of Rule 79. Nevertheless, we conclude that the
    superior court did not abuse its discretion in granting an extension to Williams to file its
    cost bill with the Clerk of Court. ConocoPhillips does not argue that it was prejudiced
    by the delay.84 It had a chance to object when the final cost bill was submitted, and it
    even succeeded in reducing the bill significantly. In this case, because of the lack of
    prejudice and because the motion for leave to enlarge time to file a motion for attorney’s

    time to seek court costs, we conclude that the superior court did not abuse its discretion
    in granting Williams an extension of the Rule 79(b) deadline.

    reduce the award of attorney’s fees.
    This court reviews an award of attorney’s fees for an abuse of discretion.85
    Under this standard, “[t]he trial court has broad discretion in awarding attorney’s fees;
    this court will not find an abuse of discretion absent a showing that the award was
    arbitrary, capricious, manifestly unreasonable, or stemmed from improper motive.”86
    When evaluating a motion for attorney’s fees, “a court should carefully consider all
    factors relevant to reasonableness.”87 There is no exhaustive list of factors a court may
    consider to determine whether the attorney’s fees claimed are objectively reasonable, but
    the factors listed in Rule 82(b)(3) may be instructive.88 Those factors include “the
    reasonableness of the claims and defenses pursued by each side” and “vexatious or bad

    faith conduct.”89 This court reviews “a trial court’s fact-based determinations regarding
    whether attorney’s fees are reasonable for an abuse of discretion.”90
    After granting Williams’s motion for enlargement of time to file a motion
    for attorney’s fees, the superior court granted Williams’s motion for attorney’s fees in
    the full amount of $465,451. As relevant here, ConocoPhillips had argued that the
    superior court should reduce the attorney’s fee award by 50% because Williams’s legal
    arguments had been rejected by the superior court at every stage of litigation.
    ConocoPhillips also sought an additional reduction for fees spent relative to Williams’s
    (unsuccessful) claim for $30 million in damages resulting from ConocoPhillips’s alleged
    tortious conduct during litigation. The superior court rejected ConocoPhillips’s requests
    for reductions in the award of attorney’s fees. The superior court “decline[d] to adjust
    the fee merely because arguments were ultimately rejected,” reasoning that it would be
    “unfair to reduce the Williams fee by 50 percent, given that it prevailed on the relief it
    sought” because “the case was very difficult” and “[t]he parties’ briefing was high
    quality and helpful.” The superior court noted that “if Williams strayed in its initial
    briefing, so too did Conoco.” The superior court also rejected the request for a reduction
    in fees relative to the tort claim, reasoning that “[b]oth [parties] adopted aggressive
    positions,” that “[n]either party spent great time or energy on these positions,” and that
    it had already concluded that it would “decline[] to adjust the fee merely because
    arguments were ultimately rejected.” ConocoPhillips raises three primary arguments on
    appeal.
    First, ConocoPhillips argues that the superior court abused its discretion by
    not reducing the award of attorney’s fees in light of the fact that the superior court
    89
    Alaska R. Civ. P. 82(b)(3)(F) & (G).

    (citations omitted).
    -45­                                      6874
    resolved the dispute on different legal grounds than those advanced by the prevailing
    party. But ConocoPhillips cites no authority for the proposition that such a reduction
    should be forthcoming simply because the prevailing party advocates a legal position not
    adopted by the court. Indeed, ConocoPhillips states that this is an issue of first
    impression in this court. Whether or not this is truly an issue of first impression, we
    reject ConocoPhillips’s proposed rule. Although the superior court ultimately rested its
    orders on grounds not directly advanced by Williams,91 the superior court necessarily
    considered the issues raised in Williams’s briefs in making its determinations.92 And the
    superior court found that Williams’s briefing was of “high quality and helpful.” We
    conclude that the superior court did not abuse its discretion by refusing to reduce an
    award of attorney’s fees when the court rested its orders on legal grounds not advanced
    by the prevailing party. Fee-shifting contracts and Rule 82 already create ex ante
    uncertainty about who will bear the ultimate burden of litigation expenses; we are
    unwilling to create additional uncertainty as to the ultimate size of litigation expenses
    by telling litigants that they must accurately predict the exact legal basis of the court’s
    holding in order to receive a full award as the prevailing party.
    Second, ConocoPhillips argues that the superior court, in stating that “if
    Williams strayed in its initial briefing, so too did Conoco,” abused its discretion by
    91
    The superior court rested its first grant of summary judgment on
    UCC § 2-207(1), an issue which Williams had not briefed, and the superior court rested
    its order on reconsideration on UCC § 2-207(3), even though Williams had supported

    The superior court must have been informed by Williams’s initial argument
    that a contract had been formed under the common law in reaching its conclusion that
    UCC § 2-207(1) governed the case and displaced the common law, and the superior
    court necessarily considered Williams’s argument on reconsideration that UCC
    § 2-207(1) governed the case before it held that summary judgment was improvidently
    granted under § 2-207(1) and instead granted summary judgment under § 2-207(3).

    “obligat[ing] the losing party to identify the prevailing party’s winning argument.” But
    ConocoPhillips misinterprets the superior court’s statement. The superior court did not
    give ConocoPhillips the burden of identifying the correct legal theory in order to prevail
    on its motion to reduce the award of attorney’s fees for Williams’s failure to identify the
    correct legal theory. Rather, the superior court merely used ConocoPhillips’s parallel
    failure to do so as evidence that the theories advanced by Williams were not
    unreasonable such that no reduction in attorney’s fees would be warranted. Accordingly,
    we reject ConocoPhillips’s argument and conclude that the superior court did not abuse
    its discretion by relying on such a parallel failure as evidence supporting the
    reasonableness of the arguments advanced by the prevailing party.
    Finally, ConocoPhillips argues that the superior court abused its discretion
    by refusing to reduce the award of attorney’s fees by the amount Williams spent pursuing
    its unsuccessful tort claim: $14,888.96. ConocoPhillips reasons that its own litigation
    position (that no contract was formed and no interest credit was due) was reasonable and
    “the central issue in the case” while Williams’s tort claim was “utterly unsupportable,”
    such that the superior court made a clearly erroneous factual finding when it
    characterized both as “aggressive positions” that nonetheless were reasonable in the
    context of the litigation. (Emphasis in original.) But beyond its bare assertion that
    “Williams’[s] attempt to recover $30 million . . . was utterly unsupportable,”
    ConocoPhillips does not offer any reason to believe that the tort claim was frivolous or
    was “not reasonably intended to advance the litigation.”93            We conclude that
    ConocoPhillips has not met its burden of showing that the superior court’s factual
    finding on this issue was clearly erroneous or that its order refusing to reduce attorney’s
    fees was an abuse of discretion.

    V.    CONCLUSION
    Because the superior court’s decision on summary judgment was correct
    and should not have been rescinded on reconsideration, the initial grant of summary
    judgment is REINSTATED and AFFIRMED. Because we conclude that the superior
    court was right in its initial grant of summary judgment, we do not reach the
    UCC § 2-207(3) or quantum meruit holdings from its order on reconsideration. The
    superior court’s rulings on attorney’s fees and costs are AFFIRMED.
