OPINION BY President Judge COLINS.
This is an appeal from the Court of Common Pleas of Montgomery County (trial court). Initially, the appeal was before the Superior Court, but was transferred by that court upon a finding that the controlling issue required analysis under the Pennsylvania Municipalities Planning Code (MPC)[1] and local zoning ordinances. The trial court denied Greylock Arms, Inc.'s (Greylock) Motion for Judgment Notwithstanding the Verdict and granted Kroiz's (Republic) Motion to Amend the February 18, 2003 order increasing the amount of damages to Republic. We affirm.[2]
This case arises from a dispute involving a 10-year renewable lease entered into in 1987. Greylock owns a parcel of land upon which a shopping center has been in existence since the 1960s. Greylock agreed to lease a 5-acre portion of its lot to Republic with the understanding that Republic intended to demolish existing buildings on the premises and construct another shopping center that would include a Triangle home improvement warehouse store. The lease was later amended to allow for a retail store of any kind or any other permitted use under the zoning ordinance. In 1988, disputes arose under the amended lease where Republic contended that in addition to the development plans already *866 approved by the municipality, a land subdivision plan was required. Republic requested that Greylock join in its subdivision application pursuant to the lease's cooperation clause before it would commence construction and begin to pay rent on the lease. Greylock refused, demanding that Republic withdraw the amended lease and allow the original ground lease to control and construct a Triangle store. When Republic insisted that subdivision approval was necessary before any specific construction plans could be approved by its lender, Greylock sued Republic for breach of the lease agreement. Greylock lost at the bench trial, and Republic's counterclaim was also denied initially. Greylock then made a Motion for Judgment Notwithstanding the Verdict that was denied. Republic's Motion for Post-Trial Relief was granted, and a verdict in favor of Republic's counterclaim was entered that reversed the earlier denial. The damages were based upon refund of the $150,000.00 security deposit and $101,638.00 of other funds expended in reliance on the lease agreement. The trial court thereby awarded a total of $251,638.00 to Republic, which amount combined with $212,634.00 of interest at the rate of 6% came to an award of $464,262.00 in damages. On appeal, the parties raise five issues.
The first issue is whether the local ordinances of Allentown or the MPC require subdivision approval where an existing shopping center leases part of its lot for the construction of another commercial use intended to be an additional shopping center. The definitions of "land development," "subdivision," and "lot" under the Allentown Zoning Ordinance neither require nor prohibit the use of subdivision on their face.[3] The same is true of the definitions under the MPC.[4] However, in the *867 context of the facts in this case, Greylock has not rebutted Republic's reasons for seeking subdivision. First, Greylock's principal was listed as owner and developer on the Development Plan when Republic was the builder. (Trial Court Finding of Fact No. 45). This is a factual misstatement in the Development Plan that could have altered whether it was approved. Second, the plan failed to define the ground lease, because there was no lease line in the plan. (Trial Court Finding of Fact No. 38). Third, Republic's lenders needed subdivision to protect their investments. All of the above were legitimate issues for Republic to seek subdivision to remedy. Indeed, the evidence of record, particularly the expert testimony, supports the trial court's finding that subdivision was both a simple and preferable solution to Republic's concerns for all parties. (Trial Court Finding of Fact No. 39 and Conclusion of Law No. 12). The trial court is correct that Greylock's failure to cooperate in Republic's reasonable request to seek subdivision was a breach of the cooperation clause of the lease agreement. (Trial Court Conclusion of Law No. 14). Further, the trial court's conclusion that subdivision would be required if Republic had constructed a building on the leased property is also supported by substantial evidence which is adequately explained in the opinion of the Honorable Arthur R. Tilson. (Trial Court Opinion, pp. 5-6). Substantial evidence is such evidence that a reasonable person would consider adequate to support the finding. Snyder v. State Ethics Commission, 686 A.2d 843 (Pa.Cmwlth.1996).
The second issue is whether Greylock was required to provide Republic with a default notice and opportunity to cure, prior to filing suit for breach of contract. Republic's action did not amount to an anticipatory breach of the lease because it was not an absolute and unequivocal refusal to perform, the requirement for anticipatory breach. 2401 Pennsylvania Avenue Corp. v. Federation of Jewish Agencies of Greater Philadelphia, 507 Pa. 166, 172, 489 A.2d 733, 736 (1985). Republic maintained throughout that it could and wished to perform so long as property lines were re-configured to the satisfaction of its lenders and the zoning ordinances of Allentown. Rather than notify Republic that Greylock regarded seeking subdivision as default and providing Republic an opportunity to cure, Greylock simply filed suit. Consequently, Greylock, and not Republic, was the party that terminated the lease. Greylock contends that providing notice of default would have been in vain and, based upon this conjecture, feels there was no duty to provide notice. We disagree. Republic *868 did not repudiate the lease; Republic sought subdivision as a means to perform under the lease. That Greylock did not wish to subdivide was not a means of making Republic's actions a repudiation of the lease. Indeed, the Court notes that the Ground Lease itself contains multiple references to giving notice to the other party if one party were to seek termination of the lease.
The third issue is whether language in the lease was ambiguous as to Republic's alleged duty to construct a 60,000-square-foot building. The language in the lease was unambiguous. Section 7.1 of Article VII of the Ground Lease, entitled "Lessee's Improvements," states in relevant part, "Lessee may, but, subject to the provisions of Section 5.5,[[5]] shall not be required to, construct a building containing a rentable floor area of approximately 60,000 square feet and other improvements on the Premises...." (Emphasis added.) Republic was permitted, not required, to construct such a building. Greylock's arguments to the contrary are without merit as we shall discuss below.
Greylock argues that Section 5.4 of Article V, entitled "Delivery of Possession," constitutes a duty-to-build clause. Section 5.4 of the Ground Lease states that upon delivery of possession, "Lessee shall be entitled to demolish the existing building on the Premises and shall thereafter promptly and diligently pursue construction of the Improvements as set forth in Article VII." As discussed above, the language in Article VII was permissive and not mandatory. In addition, Section 5.4 creates a duty only if Republic demolished the existing buildings on the lot, which under section 5.4 is permissive and not mandatory at any rate. Republic never demolished any buildings, and no duty was activated thereby.
Fourth, was it proper for the trial court to base Greylock's liability, in part, upon Greylock's failure to prove commercial fraud in Republic's obtaining an amendment to the ground lease from Greylock? It was not proper for the trial court to consider Greylock's failure to prove fraud in the inducement to amend the ground lease. The ground lease contained an integration clause in Article XXVI, Section 26.5, entitled "Entire Agreement." Greylock correctly points out that the parol evidence rule bars proof of fraudulent inducement to a contract where the contract is fully integrated. 1726 Cherry Street Partnership v. Bell Atlantic Properties, Inc., 439 Pa.Super. 141, 653 A.2d 663, petition for allowance of appeal denied, 544 Pa. 647, 664 A.2d 976 (1995). The amended lease did not alter the integration clause. The issue of fraud is irrelevant, and we do not affirm on this ground.
The final issue is whether Republic proved its damages at trial. The record reflects that Republic did prove its damages at trial. Greylock did not dispute the proffered expenses evidence when offered at trial. In its brief Greylock admits that it stipulated that if Republic's principal had testified he would have supported the listing of expenses submitted at trial in Defendants' Exhibit 40. (Brief for Appellant, p. 44). Greylock nevertheless complains that Republic's principal did not testify. Id. Yet, Greylock admits in its brief that "Lessee proved the amount of expenses." Id. Greylock cannot credibly maintain, then, that Republic failed to prove its damages when it stipulated to the *869 evidence and admitted that the expenses were proven at trial in its brief.
Accordingly, the orders of the trial court are affirmed.

AND NOW, this 26th day of July 2005, the orders of the Court of Common Pleas of Montgomery County are affirmed.
