George Lambert appeals a district court order dismissing his lawsuit for improper venue. We affirm.
I
BACKGROUND
Appellant Lambert owns and operates the Rainbow Fruit Company in Boston, Massachusetts, which sells Christmas trees and wreaths at retail during the holiday season. Appellees Sam and Joan Kysar operate a Christmas tree farm in Woodland, Washington. From 1987 through 1989, Lambert purchased Christmas trees at wholesale from the Kysars pursuant to a written form contract signed by both parties. The front of the order form contained spaces in which the size, grade, quantity, and price of each Christmas tree order could be filled in; a small space at the bottom of the page, denominated “other”, was used by the parties to note additional *1112 terms and conditions. The back of the order form stated the fixed terms of the contract and provided, inter alia, that
“[t]he terms and conditions of the order documents applicable to this transaction shall be interpreted under the case and statutory law of the State of Washington. In the event any action is brought to enforce such terms and conditions, venue shall lie exclusively in Clark County, Washington.”
In July 1989, the Kysars visited Boston to discuss Lambert’s needs for the upcoming Christmas season. On their return to Washington, they sent Lambert an order form, filled out and signed by Joan Kysar. The numbers handwritten on the form by Joan Kysar provided for an order of 2600 Christmas trees at $11.60 apiece. At the bottom of the form, in the space marked “other”, Kysar wrote that the order was “[b]ased on 4 loads of 650 trees each. All trucks will be loaded to capacity. 25% deposit ... balance due on or before 12/10/89.”
Lambert received the order form in late July, but apparently thought that it overstated the quantity of trees needed for the next season. Writing on the same order form submitted by the Kysars, he changed the notation “4 loads of 650 trees each,” to read “3 loads of 550 trees”, and changed the total number ordered from “2600” to “1650.” Lambert also recomputed the total amount due and the amount of the required 25% deposit. He inserted the new figures over Joan Kysar’s handwritten figures at the bottom of the form, and returned the form to the Kysars. He made no change to the $11.60 unit price or to any other contract provision.
On August 21, 1989, in a letter to Sam and Jean Kysar, Lambert enclosed a $4785 check “for payment of the deposit on our tree order”, and stated his understanding “that shipping will be the same as last year. There will be three loads of 1,650 trees at $11.60 for a total cost of $19,140.” The record on appeal does not indicate whether the Kysars received Lambert’s letter, cashed his deposit check, or issued any written response, but on November 20, 25 and 29, in accordance with the instructions on the altered order form, the Kysars sent Lambert the requested 1,650 trees, in three loads, by overland truck. Following delivery of the trees on November 25, 29, and December 1, Lambert’s inspection allegedly revealed that the trees “were dry, not fresh, and appeared old.” Citing the allegedly defective condition of the trees, Lambert refused to pay the balance claimed by the Kysars.
In June, 1991, the Kysars filed suit in Clark County, Washington, to recover the balance claimed due. In September, 1991, Lambert filed the present countersuit against the Kysars in Massachusetts Superior Court, alleging misrepresentation, breach of contract, breach of implied warranty, and unfair business practices under Mass.Gen.L. ch. 93A. The Kysars removed Lambert’s suit to federal district court and moved to dismiss under Federal Rules 12(b)(3) and 12(b)(6), alleging improper venue and failure to state a claim on which relief could be granted. 1
On November 18, 1991, the motion to dismiss was granted without hearing, by margin order: “[The defendants’] motion to dismiss is allowed. According to the terms of contract^] suit must be filed in State Court in Washington.” We review the district court dismissal order
de novo. See Edwards v. John Hancock Mut. Life Ins. Co., 973

DISCUSSION
The order form filled out by Joan Kysar, and amended by Lambert in July 1989, provided, inter alia, that “[i]n the event any action is brought to enforce [the] terms and conditions [of the order documents], venue shall lie exclusively in Clark County, Washington.” The Kysars assert, and the district court impliedly found, that the order form expressed the terms and conditions of the agreement between the parties and that Lambert is bound by the choice of forum made in the order form. Lambert vigorously disagrees. According to Lambert, the changes he made to the quantity term on the Kysars’ order form amounted to a material alteration (and therefore a rejection) of the Kysar offer, paving the way for a counteroffer in the form of Lambert’s August 21 letter. Since the August 21 letter contained neither a forum selection clause nor an express choice-of-law provision, Lambert asserts that venue and choice-of-law rules are to be determined under general common-law and statutory principles. In particular, Lambert asserts, the Massachusetts venue remains proper under the general rules applicable to removed cases in federal courts, ie., 28 U.S.C. § 1441. 2
We agree with the first part of Lambert’s argument. The changes Lambert made to the quantity term amounted to a rejection under Article 2 of the Uniform Commercial Code, and the Kysars’ performance of the new contract amounted to an acceptance of the new terms proposed by Lambert. We disagree with the second part of Lambert’s argument, however. Lambert’s counteroffer was made in July, when he amended the order form containing the Kysars’ original offer, not in Lambert’s August 21 letter. Accordingly, the counteroffer incorporated the unamended terms and conditions contained in the original offer, including its venue and choice-of-law clauses. Since the venue clause—impliedly mandating a Washington forum—is enforceable under both state and federal common law, the district court properly dismissed the action.
*1114 A. The Contract
The parties disagree on whether a Massachusetts court would apply Massachusetts or Washington law to the formation of their contract.
See Klaxon v. Stentor Elec. Mfg. Co.,
Christmas trees are “goods” within the meaning of Uniform Commercial Code, Article II, as adopted in both Massachusetts and Washington. 3 Moreover, the common law of both jurisdictions, which remains in force under the U.C.C. except as displaced, see U.C.C. 1-103, Mass.Gen.L. ch. 106 § 1-103, Wash.Rev.Code 62A.2-103, supports the validity and enforceability of the subject contract, including its forum selection clause.
Under the law of both Massachusetts and Washington, the order form (signed and forwarded to Lambert in July 1989) comprised an offer to contract in accordance with its terms.

It set forth in detail all the material terms essential to the proposed transaction, including the price, quantity and quality of the goods. It provided a space for Lambert’s signature, to indicate that he had “read and accepted] the Terms of Sale on the reverse side of th[e] document.” It included the signature of Joan Kysar, an officer of Lewis River Tree Farm, indicating assent to be bound.
See
Restatement (Second) of Contracts § 24 (offer is “manifestation of willingness to enter into a bargain, so made as to justify another person in understanding that his assent to that bargain is invited and will conclude it”);
Gilbert & Bennett Mfg. Co. v. Westinghouse Elec. Corp.,
Under the law of both Washington and Massachusetts, Lambert’s substitution of a substantially lower quantity term amounted to a rejection of the Kysars’ offer to sell, and a counteroffer to purchase the lesser quantity of trees.

See Minneapolis & St. L.R. v. Columbus Rolling-Mill Co.,
Since Lambert’s alteration of the quantity term amounted to a
rejection
of the original offer, rather than a mere
modification
or
supplementation
of the boilerplate language in the original offer form, this is not an appropriate case for the application of U.C.C. § 2-207-(2), Mass.Gen.L. ch. 106 § 2-207(2), Wash.Rev.Code 62A.2-207(2).

B. The Forum Selection Clause
We turn to the forum selection clause. Federal courts have long enforced forum selection clauses as a matter of federal common law.
See The Bremen v. Zapata Off-Shore Co.,
Relying on early Massachusetts decisions, however, Lambert argues that forum selection clauses which oust the jurisdiction of Massachusetts courts are unenforceable under Massachusetts law.
See Nashua River Paper Co. v. Hammermill Paper Co.,
The viability of
Nute
and
Nashua River
is not determinative in the present case, however, as we think the Massachusetts courts, consistent with the contracting parties' intention, would apply Washington law to determine the enforceability of the forum selection clause.

See
Michael Gruson,
Forum-Selection Clauses in International and Interstate Commercial Agreements,
1982 U.Ill.L.Rev. 133, 156 & n. 228
[Forum Selection Clauses
] (“most states determine the enforceability of forum-selection clauses under the law governing the contract”). The present contract provides that the interpretation of the “terms and conditions of the order documents,” including the forum selection clause, must be governed by Washington law; and even though Massachusetts law on the enforcement of forum clauses is unsettled, its courts routinely enforce choice-of-law provisions unless the law chosen violates established public policy or bears no reasonable relationship to the contractual transaction between the parties.
See
Mass.Gen.L. 106, § 1-105(1);
Morris v. Watsco, Inc.,
C. Reasonableness of Washington Forum
Under federal law and Washington state law, the contracting parties’ forum selection is to be respected unless the challenging party “clearly show[s] that enforcement would be unreasonable and unjust, or that the clause was invalid for such reasons as fraud or overreaching.”
Zapata,
Lambert does not base the present claim on the ground that the forum selection clause is a “boilerplate” provision. The principal contention is that the forum selection clause should be overturned because it would be “seriously inconvenient” for Lambert. Lambert cites
Exum,
We think Lambert misinterprets
Exum.
The “serious inconvenience” test applied in
Exum
was discussed in detail by the Supreme Court in
Zapata,
which also cited the rule of Restatement (Second) of Conflicts of Laws § 80,
see
[WJhere it can be said with reasonable assurance that at the time they entered the contract, the parties to a freely negotiated private international commercial agreement contemplated the claimed inconvenience, it is difficult to see why any such claim of inconvenience should be heard to render the forum clause unenforceable. We are not here dealing with an agreement between two Americans to resolve their essentially local disputes in a remote alien forum. In such a case, the serious inconvenience of the contractual forum to one or both of the parties ... might suggest that the agreement was an adhesive one, or that the parties did not have the particular controversy in mind when they made their agreement; yet even there the party claiming should bear a heavy burden of proof.
The bases for the parties’ selection of the Washington forum in the present case are quite dissimilar. The Kysars reside and operate their business in Washington. Their interest in selecting a forum — the consolidation of litigation involving far-flung operations — was eminently reasonable. The contract in litigation has strong links to Washington, where it was accepted and largely performed. Moreover, Washington is no more “remote” from Lambert’s place of business than when he executed the order form, either on the occasion of the present agreement or prior agreements between these parties. The forum selection clause was printed clearly on the reverse side of the form, in plain language, and the contract was not so long as to make it difficult or impossible to read.
See D’Antuono v. CCH Computax Sys., Inc.,
D. Application of Forum Selection Clause
Lambert asserts, finally, that even if the district court properly dismissed the
contract
claims under Rule 12(b)(6), the contract-related tort claims were not directly covered by the forum selection clause, and issues of material fact remain in genuine dispute, precluding their summary dismissal under Rule 12(b)(6). Lambert argues, in effect, that he should be permitted to escape the consequences of the parties’ forum selection merely by alleging tortious conduct relating to the
formation
(rather than the performance) of their contract. We cannot accept the invitation to reward attempts to evade enforcement of forum selection agreements through “artful pleading of [tort] claims” in the context of a contract dispute.
Pascalides v. Irwin Yacht Sale North, Inc.,
[the Zapata fraud exception] does not mean that any time a dispute arising out of a transaction is based upon an allegation of fraud ... the clause is unenforceable. Rather, it means that [a] ... forum-selection clause in a contract is not enforceable if the inclusion of that clause in the contract was the product of fraud or coercion.
Id.
at 519 n. 14,
The better general rule, we think, is that contract-related tort claims involv
*1122
ing the same operative facts as a parallel claim for breach of contract should be heard in the forum selected by the contracting parties.

Ill
CONCLUSION
As the forum selection clause is valid, exclusive and enforceable, the present action was properly dismissed.
Affirmed.
Notes
. The Kysars invoked Rule 12(b)(3) as the procedural vehicle for urging dismissal under the forum selection clause in the order form. We have held that such dismissals are founded on Rule 12(b)(6),
see LFC Lessors, Inc. v. Pacific Sewer Maintenance Corp.,
. Lambert’s opposition to the Kysars’ motion to dismiss also seems to assert: (1) that the Kysars waived their right to plead improper venue by filing the removal petition, thereby implicitly acknowledging the district court’s authority to hear the case; and (2) that even if the removal petition did not constitute a
per se
waiver of their right to plead improper venue, in the present case waiver can be implied from the representation made in the removal petition that ”[v]enue in [Massachusetts federal] Court [was] proper under 28 U.S.C. § 1391.” Neither assertion is sound. Although it is axiomatic that a defendant must mount any challenge to venue at the earliest possible opportunity,
see Graver Tank & Mfg. Corp. v. New England Terminal Co.,
This analysis is not altered by the Kysars’ assertion, in their removal petition, that venue in Massachusetts federal district court was proper under 28 U.S.C. § 1391. Even if their assertion could be construed as a waiver of any objection to venue under 28 U.S.C. § 1391, the venue of a removed action is not governed by § 1391, but by 28 U.S.C. § 1441(a). Indeed, removal of an action to a proper forum under § 1441(a) frequently has been considered a waiver or cure of any defect in the original venue of the removed action under 28 U.S.C. § 1391.

. Christmas trees have been described as “growing crops or other things attached to realty and capable of severance without material harm thereto,” U.C.C. § 2-107, Mass.Gen.L. ch. 106 § 2-107(2) (1979); Wash.Rev.Code 62A.2-107(2).
See Groth v. Stillson,
. As the evidentiary foundation for determining the formation of the parties’ contract was either undisputed or consisted of writings, Lambert’s present challenge raises issues of law for the court.
Ismert & Associates, Inc. v. New England Mut. Life Ins. Co.,
. Our analysis makes it unnecessary to address Lambert’s argument that the same result might be reached by crediting the printed condition on the reverse side of the order form: "No modifications of the terms of this agreement shall be effective unless reduced to writing and executed in writing by both parties hereto."
. Lambert’s August 21, 1989 letter of confirmation ratified and reconfirmed the terms of his counteroffer. The letter referred to "our tree order” and enclosed a deposit for the quantity of trees Lambert ordered. Nowhere did it indicate that the counteroffer was being revoked or made conditional on an assent to any additional term.
.
Roto-Lith
holds, as a matter of Massachusetts law, that a purported acceptance "which states a condition materially altering the obligation solely to the disadvantage of the offeror” operates as a counteroffer expressly conditioned on the of-feror’s assent to the additional term.
The Washington Supreme Court appears not to have ruled on the issue, but in
Hartwig Farms, Inc. v. Pacific Gamble Robinson Co.,

*1116
Wash.App. 539,
543-44,
. Lambert makes no claim that the forum selection clause was insufficiently conspicuous.
. Professor Reese served as Reporter for the Restatement (Second).
. The Supreme Court has yet to provide a definitive resolution of the
Erie
issue,
see Stewart Organization, Inc. v. Ricoh Corp.,
. This approach, which relies on the contracting parties’ choice of law as a basis for determining the enforceability of their forum selection, has been criticized on the ground that “jurisdiction and venue are concerns separate from choice of law, and ... determining the former usually precedes determination of the latter."

Linda S. Mullenix,
Another Choice of Forum, Another Choice of Law: Consensual Adjudicatory Procedure in Federal Court,
57 Fordham L.Rev. 291, 347 (1988);
see abo Instrumentation Assocs.,
It is well established that a forum selection clause does not
divest
a court of jurisdiction or proper venue over a contractual dispute. Rather, a court addressing the enforceability of a forum selection clause is to consider whether it must,
in its dbcretion, decline
jurisdiction and defer to the selected forum.
See Zapata,
. The
Nute
court expressed the view that "the greatest inconvenience [of contractual forum transfers] would be in requiring courts and juries to apply different rules of law in different
*1119
cases, in the conduct of suits,"
We think that modern caselaw developments, including the Massachusetts courts' willingness to entertain motions to dismiss based on the doctrine of forum non conveniens,
see Universal Adjustment Corp.
v.
Midland Bank, Ltd.,
Nashua River,
decided after
Nute,
noted that the rule against enforcement of forum selection clauses "related to a matter as to which uniformity of decision and harmony of law among the several jurisdictions of this country is desirable.”
These historical changes may well explain why the only other rationale for the
Nute
and
Nashua River
precedents — the presumed invalidity of contractual attempts to “oust appropriate courts of their jurisdiction,”
Nashua River,
223 Mass, at 19,
. Later federal cases, in this and other circuits, have sometimes applied an even stricter standard, requiring sophisticated commercial defendants to show that they would suffer such serious inconvenience in litigation in the foreign forum that they would be effectively deprived of their day in court.
