In this suit brought by Moshe Myerow-itz, 1 a chiropractor, to enforce a professional covenant not to compete against another chiropractor, Ellen Howard, the Superior Court (Penobscot County) issued on December 30, 1985, a preliminary injunction restraining defendant from violating that covenant pending the court’s final decision on plaintiff’s prayer for a permanent injunction. Dr. Howard attempts to appeal from that preliminary injunction, but she fails to bring this case within any exception to the final judgment rule. We accordingly dismiss her appeal.
In October 1981 Dr. Howard started in practice by becoming associated with Dr. Myerowitz at his Myerowitz Chiropractic Center in Bangor. On February 25, 1982, she signed an “Associate Doctor Agreement” with Dr. Myerowitz that included, among other things, a covenant not to compete. By that covenant Dr. Howard agreed not to practice chiropractics within a 50-mile radius of the Myerowitz Chiropractic Center for a period of 48 months immediately following the termination of the agreement. Until late 1985, Dr. Howard, as an associate of Dr. Myerowitz, practiced chiropractics and also performed invasive acupuncture treatments, the latter recently constituting about 70% of her practice.
In early November 1985 Dr. Howard terminated her association with Dr. Myerowitz and began to set up her own chiropractic office in Brewer, the city directly across the Penobscot River from Bangor. On November 26, 1985, Dr. Myerowitz filed this suit against Dr. Howard seeking, along with other relief, the issuance of a permanent injunction enforcing the covenant not to compete. Dr. Myerowitz also moved for similar injunctive relief
pendente lite.
On December 30, 1985, the Superior Court, after applying the four factors required by
Ingraham v. University of Maine at Orono,
By the final judgment rule, an interlocutory order such as a preliminary injunction is generally not appealable.
State v. Maine State Employees Association,
The death knell doctrine allows an appeal to be taken from an interlocutory order where “substantial rights of a party will be irreparably lost if review is delayed until final judgment.”
Moffett v. City of Portland,
The collateral order exception to the final judgment rule allows an immediate appeal from an interlocutory order, such as an attachment, where (1) that order involves a claim separable from and collateral to the gravamen of the lawsuit; (2) it presents a major and unsettled question of law; and (3) there would be irreparable loss of the rights claimed in the absence of immediate review.
See Hanley v. Evans,
Since the final judgment rule is a judge-made prudential rule, we are not precluded from fashioning an additional exception “where extraordinary circumstances warrant it.”

sociation,
In conclusion, Dr. Howard has failed to bring her appeal within any of the established exceptions to the final judgment rule or to show any other principled basis upon which we should make a special exception to our customary rule that orders for preliminary injunctions are not appealable.
The entry is:
Appeal dismissed.
All concurring.
Notes
. The named plaintiff in this case is a professional corporation bearing the title "Moshe Myerowitz, D.C., P.A.,” which does business as the "Myerowitz Chiropractic Center.” For convenience, Dr. Moshe Myerowitz, the principal in the corporation bearing his name, will in this opinion be treated as the plaintiff.
. In contrast,
Moffett v. City of Portland,
. On the record before us, there appears now to be no possible inadequacy in the $150,000 security. If Dr. Howard’s aggregate damages should in time threaten to exceed that sum because of litigation delays or otherwise, her proper avenue to relief is a motion in the Superior Court to modify the preliminary injunction to increase the amount of the required security.
