OPINION OF THE COURT

HUTCHINSON, Circuit Judge.

Appellant, Robert D. Schulman ("Schulman"), t/a Maxi's Express ("Maxi's"), appeals an order of the United States District Court for the Eastern District of Pennsylvania granting summary judgment in favor of appellees, J.P. Morgan Investment Management, Inc. ("J.P. Morgan") and Widener Funding Corporation, Inc. ("Widener") (collectively "mortgagee"), on Schulman's claim that the mortgagee intentionally interfered with contractual relations between him, as tenant of a commercial building, and Widener Associates Limited Partnership ("WALP"), the landlord. The order also granted summary judgment to the mortgagee on its counterclaim for a declaratory judgment that no valid, enforceable lease existed.

For the reasons that follow, we hold the district court had subject matter jurisdiction over the question raised in Count I of Schulman's complaint and the portion of J.P. Morgan's amended pleading styled as a counterclaim despite WALP's absence as a party. On the merits of that issue, we conclude that the district court correctly determined there was no existing lease with which the mortgagee could have tortiously interfered. No lease existed between WALP and Schulman because the draft leases on which all of the negotiations between Schulman and WALP were based explicitly required execution by the landlord, an event that never happened. In addition, even if we assume Schulman had a reasonable probability of obtaining a lease absent J.P. Morgan's and Widener's interference Schulman's alternate claim for interference with a prospective contractual relation between himself and WALP fails as a matter of law because Morgan and Widener were acting in good faith to protect their legal and financial interests as mortgagee of the premises Schulman sought to lease from WALP. Accordingly, we will affirm the district court's order in all respects.

I.

In 1990 WALP, the owner of the Widener Building in Philadelphia, began a major renovation of the building to attract upscale tenants. Jeffrey Kelter ("Kelter") was the principal acting on WALP's behalf regarding the renovation. Equitable Life Assurance Society of the United States ("Equitable Life") began funding the building's renovation under a construction loan agreement with WALP dated June 8, 1990. The agreement included among other documents a Mortgage and Assignment of Leases and Rents, both of which were publicly recorded on June 15, 1990 under Pennsylvania's recording laws, 21 Pa.Cons.Stat.Ann. §§ 321-471 (deeds), 621-28 (mortgages) (1955 Supp. 1994). Equitable Life assigned these documents to Widener under an "Assignment of Loan Documents" which was also publicly recorded on July 24, 1990. As recited in the Mortgage, WALP and Widener also executed a Permanent Loan Agreement dated June 8, 1990 in which Widener agreed to loan WALP up to $72 million for renovations, including a takeout of Equitable Life's construction financing. Both the Assignment of Leases and the Permanent Loan Agreement provided WALP would not lease any part of the building without the prior written consent of Widener, the assignee.

As of April 1, 1992, Widener had loaned WALP approximately $63 million to finance the renovations. Anne Pfeiffer, Vice President of both Widener and J.P. Morgan, supervised the loan and was responsible for approving new leases on Widener's behalf.

In the summer of 1990 Kelter and Schulman began discussing plans for Schulman to operate Maxi's, a food establishment in the lobby of the Widener Building. It is undisputed that both Kelter and Schulman anticipated that a lease would be executed for Schulman's establishment at some later date. Under the construction arrangement, the tenants received the first year's rent free of charge, which in Schulman's case amounted to $56,280. Schulman agreed to "contribute" this amount personally to Kelter for construction and obtained an offsetting construction allowance from Kelter. Schulman invested an additional $35,000 towards construction costs.

Kelter participated in and approved the design plans for Maxi's before construction began and forwarded them to Pfeiffer. According to Schulman, Kelter told him that he alone made decisions concerning the premises to be leased and that he never told Schulman that Widener and J.P. Morgan had to approve the lease. Schulman admits, however, that he knew Pfeiffer was connected with the lender and that she wanted to review the draft leases prior to execution. Construction began in September of 1991 despite the fact no lease had yet been signed.

Kelter sent Schulman three draft leases dated June 4, 1990, March 19, 1991 and August 6, 1991 respectively prior to commencing construction. Schulman reviewed these drafts himself and his counsel, Martin Herring Associates and later Drinker, Biddle Reath, also reviewed at least two of the drafts. Schulman noted several objections on the drafts, some of which were incorporated into subsequent drafts. According to Schulman, the third draft lease dated August 6, 1991, set forth all of the material agreed-upon terms. Schulman never objected to a provision appearing in all of the draft leases that expressly required WALP's approval and signature, as well as delivery of a fully executed lease, before any binding lease agreement would arise.

As construction continued, Schulman repeatedly tried to obtain an executed lease. Kelter reassured him each time that Schulman had a lease and had nothing to worry about. Though neither WALP nor Widener executed any of the draft leases, Schulman contends that a ten-year lease for the premises commenced in October or November 1991 when Schulman began construction of his establishment and the terms of this lease, agreed upon by August 6, 1991, are embodied in a fourth draft dated January 31, 1992 which FKB sent to Schulman on February 4, 1992.

Maxi's opened for business on December 2, 1991 despite the absence of an executed lease. After the renovated Widener Building's official grand opening celebration on December 12, 1991, Pfeiffer told Kelter she did not like Maxi's appearance and called it her "worst nightmare." Appendix to Brief of Robert D. Schulman ("App.") at A-91. Shortly thereafter, according to Schulman, Kelter began, for the first time, to express displeasure about Maxi's aesthetics and appearance and suggested physical and operational improvements. Schulman agreed to the suggestions but could not implement them because of a lack of sufficient funds. Kelter agreed to provide funding for the improvements but never did so.

On February 3, 1992, FKB employee Stephen Butte sent Schulman a letter confirming the amount of rent he now owed "pursuant to the terms of your lease." App. at A-200. On February 4, 1992, another FKB employee, Jennifer Pancoast, sent Schulman a second letter enclosing three "approved execution copies of the Lease Agreement for your space at The Widener Building." App. at A-97.

In March of 1992 Kelter told Schulman he had no lease and ordered him to vacate the premises. Kelter offered to compensate Schulman for his out-of-pocket expenses and prior rent checks. Schulman refused the offer. WALP filed suit for ejectment in the Philadelphia Court of Common Pleas on May 18, 1992. Kelter also moved for a preliminary injunction. After four days of hearings, Kelter abandoned that motion.

In May of 1992 Schulman filed a complaint in the district court against J.P. Morgan and Widener alleging intentional interference with existing or prospective contractual relations. On January 19, 1993, J.P. Morgan and Widener moved to amend their answer to include what they called a counterclaim for a declaratory judgment that Schulman did not have a valid, enforceable lease. Ten days later they moved for summary judgment and sanctions.

On April 22, 1993, the district court granted J.P. Morgan's and Widener's motions to amend their answer and also concluded WALP was not an indispensable party on the counterclaim under Federal Rule of Civil Procedure 19. On August 19, 1993, the court granted the mortgagee's motion for summary judgment against Schulman on all claims, including the so-called counterclaim for a declaratory judgment, but declined to impose sanctions. In its opinion the district court held Schulman could not prevail on his Count I claim for intentional interference with an existing contract because both WALP and Widener were required to consent to any lease and therefore Schulman had no existing lease with WALP. It also held Schulman had no reasonable prospect of obtaining a lease. Alternately, the district court held any interference was privileged because J.P. Morgan and Widener, as mortgagee and assignee of the leases, had both a legal and financial interest in the transaction. Finally, the district court declared Schulman had no valid, enforceable lease for the premises. Schulman filed a timely notice of appeal.

II.

Because Schulman is a Pennsylvania citizen while J.P. Morgan and Widener are New York corporations with their principal places of business in New York and the claimed damages exceed $50,000, the district court had subject matter jurisdiction under 28 U.S.C.A. § 1332(a) (West 1993) when Schulman filed this case. We have appellate jurisdiction over the district court's final order granting summary judgment under 28 U.S.C.A. § 1291 (West 1993). Accordingly, all facts in the record, and all reasonable inferences deduced therefrom, will be construed in the light most favorable to Schulman, the non-moving party. Mellon Bank Corp. v. First Union Real Estate Equity and Mortgage Invs., 951 F.2d 1399, 1404 (3d Cir. 1991).

The district court's conclusion that WALP is not an indispensable party under Federal Rule of Civil Procedure 19(b) is reviewed for abuse of discretion. Janney Montgomery Scott, Inc. v. Shepard Niles, Inc., 11 F.3d 399, 403 (3d Cir. 1993). We exercise plenary review over the district court's grant of summary judgment. Mellon, 951 F.2d 1399, 1404 (3d Cir. 1991); see Fed.R.Civ.P. 56(c). We also review a district court's decision to review or dismiss an action under the Declaratory Judgment Act, 28 U.S.C.A. §§ 2201, 2202 (West 1982 Supp. 1994), for abuse of discretion. See United States v. Pennsylvania, Dep't of Envtl. Resources, 923 F.2d 1071, 1073 (3d Cir. 1991).

III.

In response to the mortgagee's motion to amend its answer to assert as a counterclaim for a declaratory judgment its argument that no lease existed, Schulman argued in the district court that WALP was an indispensable party because its presence was essential to resolving the mortgagee's counterclaim. He also argued that a decision on the mortgagee's counterclaim would expose him to a substantial risk of inconsistent rulings if WALP were not joined because he would be collaterally estopped in the pending state court ejectment action by a declaratory judgment that no lease exists, but WALP would not be collaterally estopped if the district court decided a lease did exist.

The district court granted the mortgagee's motion to add the attack on the lease's existence that was called a counterclaim, expressly rejecting Schulman's contention that WALP was an indispensable party. The district court first noted Schulman would not be prejudiced by the proposed counterclaim because all questions relating to the existence of Schulman's lease were already at issue in Schulman's own claim of intentional interference with contractual relations. It also stated its ruling on the counterclaim would not interfere with or complicate the pending eviction action against Schulman in state court:

Whether Mr. Schulman had an enforceable lease or not is an entirely separate question from the one now in state court of whether Mr. Schulman has any rights against the landlord. Moreover, my ruling need not prompt those parties to dispute the ruling's collateral estoppel effect. If I find, after full and fair litigation on the merits, that there was no lease, Mr. Schulman cannot re-litigate that issue in state court. See Parklane Hosiery Co., Inc. v. Shore, 439 U.S. 322, 328, 99 S.Ct. 645, 650, 58 L.Ed.2d 552 (1979). If, on the other hand, Mr. Schulman is concerned that the landlord will try to re-litigate the issue should I find there was a lease, he can accept the landlord's counsel's proposal that both Mr. Schulman and the landlord waive their rights to re-litigate the existence of the lease.

Schulman v. J.P. Morgan Investment Management, Inc., No. 92-cv-02853 (E.D.Pa. April 22, 1993) (footnote omitted) (order granting motion to amend). Finally, the district court stated "[w]hile the landlord may be an important witness on the issue of whether the requirements of a Widener Building lease were satisfied, he need not be a party to Schulman's suit against the building's lender for intentional interference." Id. (emphasis in original).

Schulman did not argue on appeal that the district court's order granting the mortgagee's motion to amend its answer to assert a counterclaim for a declaratory judgment was erroneous. Nevertheless, prior to oral argument we asked the parties to submit letter memoranda addressing the effect of WALP's non-joinder under Rule 19(b). See Finberg v. Sullivan, 634 F.2d 50, 55 (3d Cir. 1980) (in banc) (this Court on appeal can raise sua sponte problem of joinder without motion of parties) (citing Provident Tradesmens Bank Trust Co. v. Patterson, 390 U.S. 102, 111, 88 S.Ct. 733, 738-39, 19 L.Ed.2d 936 (1968)).

The parties assumed that the only basis for jurisdiction was diversity. Therefore, in both the district court and here they briefed the jurisdictional issue in terms of the Rule 19 distinction between necessary and indispensable parties. In doing so, they overlooked the possibility of supplemental jurisdiction under 28 U.S.C.A. § 1367 (West 1993) that would be present if J.P. Morgan's amended pleading claiming that no lease exists is truly a counterclaim. See 6 Charles A. Wright Arthur R. Miller, Federal Practice and Procedure §§ 1414 at 99, 1422 at 170, 1436 at 274-76 (1990). J.P. Morgan's claim that no lease exists may, however, be no more than a defense to Count I of Schulman's complaint, not a counterclaim. See Fed.R.Civ.P. 8(c) (permitting court to relabel improperly labeled counterclaims and defenses). If this claim is mislabeled, consideration of WALP's status as a necessary or indispensable party under Rule 19 would be required.

Accordingly, whether the amended complaint's claim that the lease does not exist is treated as a counterclaim or a redundant defense is immaterial to the district court's jurisdiction over J.P. Morgan's contention that no lease ever existed. Moreover, if it is not a redundant defense, we disagree with the dissent's conclusion that the district court abused its discretion in addressing the merits of that contention and resolving it in favor of J.P. Morgan and against Schulman.

A.

Supplemental jurisdiction under section 1367 would not be available if the mortgagee's attack on the existence of the lease that is the basis of Count I of Schulman's complaint is not a true counterclaim, but consideration of the merits would nevertheless be proper unless WALP is not an indispensable party under Federal Rule of Civil Procedure 19(b). For the reasons hereinafter given, we conclude WALP is not indispensable. Rule 19 sets forth a two step procedure for determining whether a person is an indispensable party. See Sindia Expedition, Inc. v. Wrecked and Abandoned Vessel, 895 F.2d 116, 121 (3d Cir. 1990); Abel v. American Art Analog, Inc., 838 F.2d 691, 694-95 (3d Cir. 1988). Under the rule, a court must consider whether an absent party is "necessary" and "indispensable." We will first consider whether WALP is a "necessary" party to this action.

Schulman argues the landlord is necessary under both Rule 19(a)(2)(i) and Rule 19(a)(2)(ii). Under Rule 19(a)(2)(ii) we ask whether nonjoinder would subject Schulman to a substantial risk of inconsistent obligations if the district court decided there was a lease and WALP subsequently challenged this finding in state court.

We recognize that a decision in this action on the mortgagee's defense to Schulman's claim for tortious interference denying the existence of any lease between Schulman and WALP could affect the pending state court action, but whether WALP would be collaterally estopped is ultimately a matter for the state court to decide when the issue arises. Cf. Janney, 11 F.3d at 407 (declining "to hold that any potential effect the doctrine [of stare decisis] may have on an absent party's rights makes the absent party's joinder compulsory under Rule 19(a) whenever 'feasible'"). Nevertheless, under general principles of collateral estoppel or issue preclusion, a strong argument can be made that WALP would be bound. Moreover, during the district court proceedings WALP agreed to be bound by the district court's determination on the lease's existence. We will therefore assume, without deciding, that WALP is a necessary party under Rule 19(a) and go on to consider whether it is also indispensable under Rule 19(b).

B.

The extent to which a judgment rendered in WALP's absence might be prejudicial to it or to those already parties to this case must be considered under Rule 19(b) as well as 19(a). Prejudice under Rule 19(b), like impairment of an absent party's rights under Rule 19(a)(2)(i), implicates principles of collateral estoppel or issue preclusion. Under Pennsylvania law on issue preclusion, a party may be precluded from relitigating an issue only if:

"(1) the issue decided in the prior adjudication was identical with the one presented in the later action; (2) there was a final judgment on the merits; (3) the party against whom the plea is asserted was a party or in privity with a party to the prior adjudication; and (4) the party against whom it is asserted has had a full and fair opportunity to litigate the issue in question in a prior action."

Janney, 11 F.3d at 409 n. 12 (quoting Sanders v. Sanders, 384 Pa. Super. 311, 558 A.2d 556, 560 (1989) (citation omitted), allocatur denied, 525 Pa. 635, 578 A.2d 930 (1990)). Thus, if the landlord was in privity with J.P. Morgan and Widener and they adequately represented its interests, WALP would be collaterally estopped. See id. at 410. Yet, under Rule 19(b), unlike Rule 19(a), collateral estoppel is only a necessary condition of dismissal, not a necessary and sufficient condition.

Though it would be logically inconsistent for J.P. Morgan to succeed in this federal action on its defense that no lease existed with respect to the tortious interference claim, and the landlord to lose in the state court action because the state court decided the parties' actions and oral communications brought a lease into existence, logical inconsistency does not make an absent party indispensable. See Field v. Volkswagenwerk AG, 626 F.2d 293, 301-02 (3d Cir. 1980) ("[T]he possibility of a subsequent adjudication that may result in a judgment that is inconsistent as a matter of logic [does not] trigger the application of Rule 19.") (emphasis added).

In the district court, WALP offered to agree to be bound by any determination of the lease issue, even if not joined, provided Schulman would also agree to be bound. WALP specifically informed the district court that it could

submit an affidavit . . . in which it would agree to be bound by a decision rendered in this action as to the existence of a lease and would expect, in return, plaintiff's acknowledgement and stipulation that he would be bound by [the district court's] determination of the lease issue so that plaintiff would not seek to relitigate the issue in state court. If WALP were to submit such an affidavit and plaintiff such an acknowledgment and stipulation, there would be no need to join WALP as a party defendant and there would be no possibility of further procedural wrangling in the state court on the lease issue.

Letter from Leonard S. Baum, Esq., counsel for mortgagee, to District Court dated February 16, 1993, Exh. "B" of Memorandum of Law of Appellees to this Court dated March 11, 1994. Schulman declined this offer and no such affidavit or stipulation was filed. We think that Schulman, even absent this stipulation, would be bound by the district court's resolution of the issue concerning existence of the lease. Given WALP's willingness to be bound, any judgment rendered in WALP's absence would be mutually dispositive of the case.

C.

Because the mortgagee's counterclaim for a declaratory judgment on the lease's existence mirrors an essential element of Schulman's own claim, i.e. the existence of a lease, we do not think the district court abused its discretion when it concluded Schulman should not be able to demand WALP's presence as a condition of an order adjudicating the merits of the dispute over the lease's existence. Dismissal under Rule 19(b) is subject to a district court's discretionary analysis of equitable considerations, as is its decision to entertain a request for a declaratory judgment. In either case we do not think the district court abused its discretion. The equities favor WALP and the mortgagee, not Schulman, because it was Schulman who chose to divide this dispute between two independent forums and then rejected WALP's proposal to stipulate that any decision in the district court would be binding on both of them in the ongoing state court proceedings. Accordingly, we conclude the district court had subject matter jurisdiction over the merits of whether J.P. Morgan's counterclaim is treated as such or as no more than a redundant defense to Count I of Schulman's complaint. It therefore follows that we also have appellate jurisdiction to decide the issues the parties have raised about the lease's existence on their merits.

IV.

Turning to the merits of that issue, Schulman argues that a valid, enforceable lease exists because he relied on Kelter's assurances that he would obtain one as well as the FKB employees' confirmed acceptance of the final draft. Schulman relies on Emerman v. Baldwin, 186 Pa. Super. 561, 142 A.2d 440 (1958). There, defendants orally agreed to lease a house to plaintiffs for two years at a specified price. Id. at 443. Defendants acknowledged the agreement as to terms by letter but in the letter stated the agreement was nevertheless subject to execution and delivery of defendants' standard lease form. Id. Under the circumstances, the court held that the minds of the parties had met on the essential provisions of the lease and a valid leasehold agreement was made because the form's provisions were known to plaintiffs and the defendants believed the negotiations had resulted in a binding contract. Id. at 445.

Emerman is distinguishable from this case. The defendants in Emerman expressed their willingness to accept the terms agreed upon during the negotiations as a binding contract and objectively indicated they intended the executed standard form would be a mere formality, serving only as evidence of the agreed upon terms. In contrast, here WALP always made clear its intent not to be bound by any lease until a written lease was executed. Paragraph 57 of the January 31, 1992, draft lease, which Schulman contends embodies all of the terms of the purported lease, expressly bars any agreement from taking effect until both the landlord and tenant have signed and delivered it. It provides in a distinctive, capitalized typeface:

57. Delivery For Examination. DELIVERY OF THE LEASE TO TENANT SHALL NOT BIND LANDLORD IN ANY MANNER, AND NO LEASE OR OBLIGATIONS OF LANDLORD SHALL ARISE UNTIL THIS INSTRUMENT IS SIGNED BY BOTH LANDLORD AND TENANT AND DELIVERY IS MADE TO EACH.

App. at A-150. Schulman was on notice of WALP's intent not to be bound until it signed the lease throughout the negotiations. Schulman and his attorneys reviewed each of the four draft leases. All contained this provision and they never objected to it. Schulman's attorney expressly cautioned him on the necessity of formal execution. Schulman concedes WALP never signed any of the draft leases.

Despite the clear language of paragraph 57, Schulman argues that the January 31, 1992, draft lease and the two letters he received from FKB employees in February 1992 create a sufficient writing to evidence the lease terms. His argument might be sufficient to overcome the defense of the statute of frauds, but the issue here is whether parties whose minds had met on the need for a formal fully executed document before any binding contract arose consummated their agreement, not whether there was sufficient written evidence of the proposed terms of that agreement. Paragraph 57 explicitly requires the signing and delivery of the lease itself. The letters' references to the draft as a lease did not transform it into one. Under Pennsylvania law, when one party has expressed an intent not to be bound until a written contract is executed, the parties are not bound until that event has occurred. See Essner v. Shoemaker, 393 Pa. 422, 143 A.2d 364 (1958). In this case, no lease could exist until WALP executed and delivered it. In response to the mortgagee's motion for summary judgment, Schulman points to nothing that could create a genuine issue of fact on the existence of a binding lease. For the same reasons, Schulman's alternate argument based on Valvano v. Galardi, 363 Pa. Super. 584, 526 A.2d 1216, 1220 (1987) that commencement of operations and payment of rent to WALP is part performance sufficient to take the case outside Pennsylvania's statute of frauds, Pa.Stat.Ann. tit. 68, § 250.202 (1994), also fails. The district court did not err by granting summary judgment in favor of the mortgagees on Schulman's claim for intentional interference with existing contractual relations.

V.

Schulman also asserts a claim for intentional interference with prospective contractual relations. To succeed, Schulman must show the prospective contract has an objectively reasonable probability of coming into existence. See Thompson Coal Co. v. Pike Coal Co., 488 Pa. 198, 412 A.2d 466, 471 (1979). We think there is sufficient evidence in this record to withstand summary judgment on the issue of whether Schulman had a reasonable probability of obtaining a lease from WALP absent the mortgagee's interference. We must therefore consider whether the mortgagee's conduct was privileged.

The Pennsylvania Supreme Court has "repeatedly looked to the Restatement as authority for the elements of a cause of action for intentional interference with existing contract relations." Adler, Barish, Daniels, Levins Creskoff v. Epstein, 482 Pa. 416, 393 A.2d 1175, 1182 n. 13 (1978) (adopting Restatement of Torts §§ 766, 767 as definition of intentional interference), appeal dismissed and cert. denied, 442 U.S. 907, 99 S.Ct. 2817, 61 L.Ed.2d 272 (1979). It has also adopted portions of the Restatement relating to intentional interference with prospective contractual relations. See Glenn v. Point Park College, 441 Pa. 474, 272 A.2d 895, 897 (1971). Section 769 of the Restatement (Second) of Torts excuses interference committed by a person with a financial interest in another's business if that interest may be affected by commercial relations between others. Restatement (Second) of Torts § 769 (1979). It provides:

One who, having a financial interest in the business of a third person[,] intentionally causes that person not to enter into a prospective contractual relation with another, does not interfere improperly with the other's relation if he

(a) does not employ wrongful means and

(b) acts to protect his interest from being prejudiced by the relation.

Id. (emphasis added); see also Yaindl v. Ingersoll-Rand Co., 281 Pa. Super. 560, 422 A.2d 611, 625 (1980) (citing Restatement (Second) of Torts § 769 approvingly), abrogation on other grounds recognized by Yetter v. Ward Trucking Co., 401 Pa. Super. 467, 585 A.2d 1022 (1991) (citing Paul v. Lankenau Hosp., 524 Pa. 90, 569 A.2d 346 (1990) and Clay v. Advanced Computer Applications, 522 Pa. 86, 559 A.2d 917 (1989)). As the district court recognized, illustration 1 to that section is similar to this case. Illustration 1 provides:

A provides the financial backing for B's theatrical production. The arrangement is in the form of a loan for the purposes of the production. While B undertakes to repay the loan in any event, in fact the chances of repayment depend upon the success of the play. B is about to engage C to play the leading role. Under the conditions stated in Clauses (a) and (b), A's interference with the prospective relation by causing B not to have C play that role is not improper.

Restatement (Second) of Torts § 769 cmt. c, illus. 1. The interest of a mortgage lender is clearly an economic or financial interest that falls within the scope of the privilege. See, e.g., Cloverleaf Dev., Inc. v. Horizon Fin. F.A., 347 Pa. Super. 75, 500 A.2d 163, 167 (1985) (lender acted in its own financial interest by demanding higher interest rate, thereby interfering with sale of mortgage).

Here, the mortgagee who is charged with interference loaned WALP $62 million for renovations; of that amount only $56,280 was allocated to Maxi's. Schulman argues this minimal financial interest is insufficient to justify the mortgagee's conduct. Schulman also argues the mortgagee's aesthetic concerns are invalid because there is no evidence Schulman could not pay the rent as agreed. Schulman misses the point. J.P. Morgan has $62 million tied up in the Widener Building and if the building doesn't succeed in attracting up-scale tenants, J.P. Morgan's ability to recoup its loan is jeopardized. To the extent Maxi's appearance would harm the building's ability to attract first-class tenants, J.P. Morgan's concerns are valid. WALP implicitly acknowledged this by granting the mortgagee the right to disapprove tenants.

Interference is also privileged when the actor believes in good faith that his legally protected interest may otherwise be impaired by the performance of the contract. See Advent Sys., Ltd. v. Unisys Corp., 925 F.2d 670, 673 (3d Cir. 1991); Geofreeze Corp. v. C. Hannah Constr. Co., 588 F. Supp. 1341, 1345 (E.D.Pa. 1984); Cloverleaf, 500 A.2d at 168. Section 773 of the Restatement (Second) of Torts excuses interference by persons protecting legal interests. Restatement (Second) of Torts § 773 (1979). It provides:

One who, by asserting in good faith a legally protected interest of his own or threatening in good faith to protect the interest by appropriate means, intentionally causes a third person not to perform an existing contract or enter into a prospective contractual relation with another does not interfere improperly with the other's relation if the actor believes that his interest may otherwise be impaired or destroyed by the performance of the contract or transaction.

Id. (emphasis added); see also Kelly-Springfield Tire Co. v. D'Ambro, 408 Pa. Super. 301, 596 A.2d 867, 872 (1991) (relying on Restatement (Second) of Torts section 773); Geofreeze, 588 F. Supp. at 1345-46 (citing section 773 approvingly). The Restatement gives an actor this defense only if it has a legally protected interest and, in good faith, asserts the interest or threatens to protect it by appropriate means. Restatement (Second) of Torts § 773 cmt. a.

The Mortgage and Loan Documents WALP and Widener executed expressly prohibit WALP from entering into any lease without Widener's prior written consent. Section 6.01.1 of the Mortgage forbids WALP from executing leases without the mortgagee's written consent. Section 9.01(k) makes WALP's sale, conveyance, encumbrance, or other transfer of control without the mortgagee's prior written consent an event of default. Section 10.01 again forbids transfers of any kind without the mortgagee's prior written consent. WALP also covenanted in section 4(k) of the Assignment of Leases to Equitable Life that it would:

[n]ot lease any part of the Property, or renew or extend the term of any Lease of any part of the Property without, in each case, the prior written consent of the Assignee or as expressly provided for in the Loan Agreement[.]

App. at A-410. In the instant case, Widener acted in good faith pursuant to its own reserved, contractual right in the mortgage and loan documents between it and WALP to oversee the selection of the Widener Building tenants.

Thus, the mortgagee's conduct is not improper based on both its financial and legal interests in the transaction.

VI.

For the foregoing reasons the order of the district court will be affirmed.

HUTCHINSON, Circuit Judge.
