Employers Insurance of Wausau (“Wau-sau”) appeals the district court’s 1 order granting the defendant’s motion to dismiss Wausau’s complaint filed pursuant to the Declaratory Judgment Act, 28 U.S.C. § 2201. Wausau argues on appeal that the district court erred in abstaining in favor of a pending state court case which raised essentially identical issues. After careful consideration, we find that the district court did not abuse its discretion and affirm.
I.
This case involves an insurance coverage dispute between an insurance company, Wau-sau, and its insured, Missouri Electric Works, Inc. (“MEW”), over whether an insurance policy includes coverage for costs relating to the environmental cleanup of a piece of land owned by MEW.
Since 1953, MEW has been in the business of buying, selling, repairing, and refurbishing electrical equipment and devices. While doing business, MEW used certain chemicals that contaminated the land on which MEW conducted its operations (“MEW Site”). After testing the MEW Site, the Environmental Protection Agency (“EPA”) ordered MEW and other potentially responsible parties to remedy the contamination. The EPA *1374 also requested that MEW reimburse- it for current and anticipated response costs arising out of the EPA’s involvement with the MEW Site.
On June 1, 1992, MEW sued Wausau in the circuit court of Cape Girardeau County, Missouri. In its petition, MEW alleged that Wausau, as its liability insurer from 1957 through 1969, had a duty to defend and indemnify MEW for claims and costs arising from the contamination of the MEW Site. MEW sought declarations and damages arising from this duty to defend and indemnify. On July 2,1992, Wausau removed the case to the United States District Court for the Eastern District of Missouri. Thereafter, on November 5,1992, Wausau filed a motion for summary judgment. MEW then filed a motion for leave to dismiss the case without prejudice, which the court granted on December 18, 1992.
On that same date, Wausau filed the declaratory judgment complaint which is the subject of this appeal. In its complaint, Wausau asked the court to declare that the insurance policies Wausau had issued to MEW failed to give rise to. a duty to defend or indemnify MEW for expenses incurred in connection with cleaning up the MEW Site. On January 21, 1993, MEW filed a motion to dismiss Wausau’s complaint on the basis that the lawsuit failed to raise any claims that were not already covered by- a lawsuit that MEW had filed in the Circuit Court of Cape Girardeau County in 1989. That lawsuit, to which Wausau was added on December 14, 1992, named other insurance companies who had allegedly provided liability insurance coverage for MEW from 1969 through 1988 and addressed the same issue of liability for response costs.
The district court granted MEW’s motion to dismiss. Specifically, the district court held that exceptional circumstances

existed which warranted abstention.

II.
A district court is not obligated to exercise jurisdiction in a diversity case brought under the Declaratory Judgment Act.
Brillhart v. Excess Ins. Co.,
(1) whether there is a res over which one forum has established jurisdiction, (2) the inconvenience of the federal forum, (3) whether maintaining separate actions may result in piecemeal litigation, unless the relevant law would require piecemeal litigation and the federal court issue is easily settled, (4) which case has priority — not necessarily which case was filed first but a greater emphasis on the relative progress made in the cases, (5) whether state or federal law controls, and (6) the adequacy of the state forum to protect the federal plaintiffs rights.

Applying these factors to this case, the desire to avoid piecemeal litigation and the fact that this issue is controlled by state law all counsel in favor of abstention. 4
Avoiding Piecemeal Litigation
MEW has sued both Wausau and USF & G in the pending state court action for damages and indemnification. Although the poli-ey terms of coverage do not overlap to any great extent in this case, we think it is significant that a Missouri state court will decide this issue regardless of whether we exercise jurisdiction or abstain, making entirely possible conflicting opinions on the issue of whether cleanup costs are considered “damages” within a general liability policy. Conflicting opinions cause unwarranted friction between state and federal courts, a result which is obviously undesirable and avoidable in this instance.
Wausau argues, however, that MEW created the controversy and the possibility for inconsistent interpretations by filing separate suits against separate insurance carriers. In addition, Wausau argues that this case presents the possibility of duplicative, not piecemeal, litigation because the policies involved do not present the same kinds of overlapping terms of coverage as presented in the Syntex case.
We reject Wausau’s arguments for a number of reasons. First, while it is true that MEW originally filed two suits against two separate insurance carriers, these actions are not so egregious that the Court should punish MEW by subjecting it to potentially inconsistent judgments and duplicative litigation expenses. Moreover, even though an argument can be made that the litigation would be merely duplicative, rather than piecemeal, the possibility still exists “ ‘of two interpretations of the same policy language in different courts, leaving the insured possibly with insufficient coverage from the insurers after years of paying premiums.’ ”

Controlling Law
Neither party disputes that this ease involves an interpretation of Missouri law. We acknowledge that the presence of state-law issues weigh in favor of abstention only in “rare circumstances.”
See Moses H. Cone,
For the reasons stated above, we hold that the district court did not abuse its discretion by refusing to exercise jurisdiction in this case. Accordingly, we affirm the judgment of the district court.
Notes
. The Honorable Donald J. Stohr, United States District Judge for the Eastern District of Missouri.
. Under the "exceptional circumstances” test, abstention is the exception, rather than the rule, and a district court has a "virtually unflagging obligation” to exercise jurisdiction and may abstain only when exceptional circumstances exist.
Colorado River Water Conservation Dist. v. United States,
. The district court noted that two apparently conflicting Eighth Circuit opinions exist on the issue of the appropriate test to apply when determining whether to abstain from hearing a diversity case brought under the Declaratory Judgment Act. In

. Factors 1, 2, 4, and 6 are neutral in this case. Wausau argues that neutral factors should weigh against abstention in light of the Supreme Court's holding that a district court should only abstain in exceptional circumstances. Wausau cites
