POPOVICH, Judge:
This is an appeal from judgment entered in the Philadelphia County Court of Common Pleas, sitting in equity, awarding appellee Holt’s Cigar Co. (“Holt’s” or “Lessee”) liquidated and lost profits damages in the amounts of $22,000 and $53,716, respectively. The action was one for injunction and breach of commercial lease. Named defendants were appellant Philip J. Banks (“Banks”) and 222 Liberty Associates (a Pennsylvania limited partnership) (“Liberty” or “Lessor”; collectively referred to as “appellant”). We reverse the chancellor and vacate the liquidated damages award finding it an unenforceable penalty; we also reverse and vacate the lost profits award on grounds that relief in the form of unliquidated damages was not pleaded by appellee thereby creating an impermissible variance between the allegata and the probata.
Appellee Holt’s is a Pennsylvania corporation with its principal place of business at 114 South 16th Street, Philadelphia, PA. It is at this location where appellee leased from Liberty commercial property in order to engage in the retail sale of various and sundry smoking products and accessories. As already indicated, Holt’s complaint named 222 Liberty Associates and appellant, Philip J. Banks, as defendants. The complaint further averred (and this was admitted in defendants’ answer) that Banks was a general partner and general contractor of 222 Liberty Asso[581]*581dates during the relevant time period. Complaint and Answer 2-3. Preliminarily, we find the law well-settled in that this admission is suffident to impose joint and several liability on Philip Banks for any wrongful act made in the ordinary course of partnership business. See 15 Pa.C.S.A. §§ 8533(b), 8325 & 8327 (Purdon App.1990); See also Rhodes v. Terheyden, 272 Pa. 397, 116 A. 364 (1922).
On January 1, 1980, Holt’s began a ten-year term lease at the above-mentioned address. This commercial lease was for corner space fronting Sansom and 16th Streets situate on the ground floor of a multi-story building. The dispute arose out of extensive building renovation efforts undertaken by appellant in the midst of Holt’s tenancy (not at Holt’s behest). The body of the chancellor’s opinion is brief enough to be cited in full:
This civil action in equity arose out of the defendant’s performance of extensive renovations to a building in which plaintiff occupied ground floor space pursuant to a lease agreement dated December 31, 1989, [sic] and subsequent riders and addendums thereto. The lease agreement permitted the defendant landlord to conduct repair/renovation activities, however, plaintiff contended in its complaint and demonstrated at trial that the conduct of the defendant, its general partner and contractor, Philip Banks, its subcontractors and others, substantially interfered with and prevented the plaintiff from operating its business profitably. The conduct of the defendant can only be described as the total disregard of plaintiff’s rights as a tenant and in certain cases, bordering on malicious activity. On two occasions, the plaintiff was forced to seek emergency relief in the Court of Common Pleas to force the defendant to provide heat to the leased premises. As [sic] one point, the defendant sought the eviction of the plaintiff but withdrew this request when Judge Gafni personally inspected the premises and permitted the plaintiff to escrow its rent to ensure the defendant’s provided heat. A thorough review of the notes of testimony indicates the extent to which the [582]*582defendant interfered with plaintiffs business activities and totally disregarded the plaintiffs rights as a tenant.
The evidence indicated a liquidated damages provision agreed to by the parties which provided for a payment of $500.00 day where plaintiff was unable to conduct business as a result of defendant’s construction activities. The parties stipulated at trial that the number of business days at issue was 44 [excluding days closed and holidays], although plaintiff contended there were 52 [including days closes and holidays]. Plaintiff also contended that it was entitled to damages for loss of profits during the period of defendant’s business interruption and interference.
This Court found the testimony of the defendant, Philip Banks, to be incredible and highly suspect, while the testimony of plaintiff’s witnesses was credible and worthy of belief. Based upon the testimony and documentary evidence submitted by the parties, the court entered a verdict for plaintiff in the total amount of $75,716.00, which represented per diem damages of $500.00 for 44 days, plus loss of profits in the amount of $53,716.00.
The defendant contended that the plaintiff failed to prove its case by a preponderance of the evidence and that a verdict against the defendant, Philip Banks, individually, was unwarranted and unsupported by the evidence. This Court, sitting without a jury, was free to assess the credibility of the witnesses and to accept or reject testimony presented, [citation omitted]. The fact that this Court did not believe the defendant, Philip Banks, or accept his version of the facts, does not render the evidence insufficient. Likewise, a complete review of the record in this case demonstrates the existence of substantial evidence to support the verdict in plaintiff’s favor____ The verdict and judgment entered against [Banks] should stand accordingly.
Chancellor’s Op. 1-4.
On September 18, 1986, over six years into the lease, the parties negotiated an “agreement” calling for a $500 per [583]*583diem stipulated sum to be paid appellee for delayed construction/renovation of the building.1 Relevant portions of the agreement are as follows:
September 18, 1986
To: Mr. Philip Banks
This will confirm our understanding regarding the construction work being done on the outside and inside of our store: 1. You have agreed that if you do not meet the construction schedule attached, you will pay us $500.00 per day for each day delayed. In addition, if we have to close the store, which is not contemplated, there will be an abatement of rent and $1,000.00 per day for each day that we are closed.
If you agree that the above is accurate, please sign a copy of this letter and return it to us.
Very truly yours,
/s/ Robert Levinp[2]
222 Liberty Assoc.
/s/ Philip J. Banks
Philip Banks, general partner

Trial lasted for three days and filled 401 pages of transcript. On June 3, 1988, the chancellor issued the following uncaptioned notice of judgment in favor of appellees: “The court finds in favor of the plaintiff against the defendants 222 Liberty Associates & Philip J. Banks in the amount of $75,716.” Appellant timely filed motions for post-trial relief on June 6, 1988, accompanied by a supporting memorandum. Relief was denied by order of October 4, 1988. Thereafter, upon praecipe, judgment was entered in favor of appellee on January 12, 1989, in the amount of $75,716 as against defendant Banks only. It was not until March 22, 1990, that the chancellor filed an opinion—apparently in response to appellant’s notice of appeal to this court filed February 14, 1989.
Preliminarily, we note that despite one passing reference in the chancellor’s opinion evidencing his recognition of this being an action in equity, the clear inference is that he was at all times operating under the mistaken belief that the rules of procedure governing actions at law applied.3 [585]*585The proof at trial bears this out, for while appellee’s complaint requested both equitable and monetary relief in the form of liquidated damages,4 the evidence at trial was [586]*586limited exclusively to a plea for monetary damages (both liquidated and lost profit). Indeed, equitable relief was unavailable in light of the fact that all renovation efforts ceased before trial. Nonetheless, once equity (subject matter) jurisdiction properly attached, jurisdiction to enter a monetary decree for liquidated damages continued even though no disposition was made of plaintiffs initial application for injunctive relief, see Stryjewski v. Local Union No. 830, Brewery, Etc., 451 Pa. 550, 304 A.2d 463 (1973), and even though the alleged continuing harm ceased before trial. See McGovern v. Spear, 463 Pa. 269, 344 A.2d 826, 828 (1975). It has been said that a preliminary objection (either by defendant, or by the chancellor sua sponte) as to the existence of a full, complete and adequate non-statutory remedy at law, see Pa.R.C.P. 1509(c), goes to the form of the action, is not jurisdictional, and, therefore, can be waived. See Carelli v. Lyter, 430 Pa. 543, 244 A.2d 6, 8 (1968); see also Pa.R.C.P. 1509(c). No such preliminary objection was made below. Accordingly, the chancellor properly addressed appellee’s claim for liquidated damages.
LIQUIDATED DAMAGES AWARD
Appellant first contends that the $22,000 liquidated damages award must be reversed as the enforcement of a penalty. We agree.
Nearly a century ago our supreme court quite aptly articulated the policy against the enforcement of penalties in actions ex contractu:
[Wjhere the breach of agreement admits of compensation, the recovery may be limited to the loss actually sustained, notwithstanding a stipulation for a penalty. [This rule] is founded upon the principle that one party should not be [587]*587allowed to profit by the default of the other, and that compensation and not forfeiture is the equitable rule.
Kunkel & Jordan v. Wherry, 189 Pa. 198, 201, 42 A. 112 (1899) (emphasis added). Hence, the rule of validity of a liquidated damages stipulation was held to comport with the general and overarching principle of contract remedies-— compensation for damages sustained. See, e.g., Kothe v. R.C. Taylor Trust, 280 U.S. 224, 50 S.Ct. 142, 74 L.Ed. 382 (1930) (agreements to pay a fixed sum without any reasonable relation to probable damages for breach “tends to negative any notion that the parties really meant to provide a measure of compensation”); see also Keck v. Bieber, 148 Pa. 645, 646, 24 A. 170 (1892); see generally Restatement (Second) of Contracts, § 356 comment a. (noting centrality of the principle of compensation). Where a stipulated damages clause is intended as a form of punishment with the purpose, in terrorem, to secure compliance, the principles of compensation are subordinated and the provision must fail as an unenforceable penalty. See In re Plywood Company of Pennsylvania, 425 F.2d 151, 155 (3d Cir.1970) (“A penalty is said to be fixed not as a pre-estimate of probable actual damages, but as a punishment, the threat of which is designed to prevent the breach.”).
To assist in making this distinction, our courts have employed certain rules of construction that are commonly thought to provide the best indication of the parties’ intent.
The question [of whether stipulation is a penalty or a valid liquidated damages provision] ... is to be determined by the intention of the parties, drawn from the words of the whole contract, examined in the light of its subject-matter and its surroundings; and in this examination we must consider the relation which the sum stipulated bears to the extent of the injury which may be caused by the several breaches provided against, the ease or difficulty of measuring a breach in damages, and such other matters as are legally or necessarily inherent in the transaction.
[588]*588Commonwealth v. Musser Forests, Inc., 394 Pa. 205, 146 A.2d 714, 717 (1959) (citing March v. Allabough, 103 Pa. 335, 341 (1883)); see also Holmes Electric Protective Co. v. Goldstein, 147 Pa.Super. 506, 24 A.2d 161, 165 (1942). This court also has cited with approval section 339 of the Restatement (First) of Contracts:
(1) An Agreement, made in advance of breach, fixing the damages therefor, is not enforceable as a contract and does not affect the damages recoverable for breach, unless
(a) the amount so fixed is a reasonable forecast of just compensation for the harm that is caused by the breach, and
(b) the harm that is caused by the breach is incapable or very difficult of accurate estimation.
See, e.g., Harris v. Dawson, 239 Pa.Super. 316, 360 A.2d 706 (1976) (citing with approval § 399); Kraft v. Michael, 166 Pa.Super. 57, 70 A.2d 424 (1950) (same).
In light of the foregoing legal principles, conspicuously absent is any indication that the chancellor demonstrably considered whether the per diem stipulation was: (1) chosen due to the difficulties in proving with certainty the precise extent of actual damages for breach, and (2) whether the stipulated sum was agreed to and intended as a good faith pre-estimate of actual damages anticipated from delayed repairs.
We feel that it is incumbent on the trial judge to address these mixed factual and legal questions in the first instance prior to awarding liquidated damages lest we forget that compensation, not punishment, is the guiding rule. See Keck v. Bieber, 148 Pa. 645, 646, 24 A. 170 (1892) (“where [damages are stipulated to in advance] the court will always look into the question whether this is really liquidated damages or only a penalty, the presumption being that it is the latter”); see also Holmes Electric Protective Co. v. Goldstein, 147 Pa.Super. 506, 24 A.2d 161, 165 (1942) (same). While the final determination of whether a stipulated sum is for liquidated damages or a penalty is one of [589]*589law for the court to decide, see Laughlin v. Baltalden, Inc., 191 Pa.Super. 611, 159 A.2d 26, 29 (1960), it should be remembered that the pleadings and evidence reduced to findings of fact supply the court with the information necessary to make informed legal conclusions. That the facts and circumstances of each case control suggests the importance of there being detailed findings made below.
Instantly, various avenues of inquiry were available to the chancellor which might have been of assistance in discerning the parties’ intentions regarding liquidated damages. The chancellor might have examined the subject matter of the contract, particularly the nature and extent of the agreed-to repairs on the building, and the anticipated profits absent breach, to assess whether the stipulated sum was a reasonable pre-estimate of foreseeable damages due to delay. This would have been especially probative where, as here, the contract on its face was vague in its description of appellant’s specific obligations thereunder. The court also might have appropriately chosen to consider the actual amount of damages suffered due to delayed construction relative to the stipulated sum, and, hence, whether the stipulation was so grossly disproportionate to actual damages as to afford appellee a windfall. Finally, we note that parole evidence of prior negotiations offered to describe the manner through which a liquidated damages provision was arrived at, i.e., to explain the terms of a writing, is often probative of the parties’ intent. Abundantly clear from the chancellor’s opinion is that none of these avenues was investigated.
Nevertheless, we are able to glean from the record evidence which compels reversal of the liquidated damages award. Robert Levin testified at trial as to how he arrived at the $500 per diem amount included in the agreement:
We picked that [$500 per diem figure] because I had to pick some figure. We had to have some parameters within which the schedule had to be adhered to and if you went over the schedule there would have to be some sort of penalty. And we picked five hundred dollars a day, [590]*590and that seemed to be perfectly fine with everybody involved if they went over the schedule.
N.T. February 23, 1988, at 169. Moreover, it was Holt’s contention at trial that the per diem amount was intended to apply even on days that Holt’s was not open for business:
Of course, it’s our contention as we made in the opening that we are counting seven days of the week; Holt’s being open six days. But the five hundred dollar per day not being limited to business days.
N.T. February 25, 1988, at 280, 380. Lastly, and in an apparent attempt to recover both stipulated and lost profits damages, Holt’s argued “that [the] contract of September 18, 1986 ... entitled] the plaintiff to a five hundred dollar a day penalty, if you will, not liquidated damages....”5 N.T. February 23, 1988, at 3; see also Brief for Appellee at 9 (noting that “the $22,000 is not a liquidated damage, and is separate and apart from the lost profit damages”).
We find it abundantly clear from the trial testimony and accompanying arguments that Holt’s, acting through Mr. Levin, chose the stipulated sum not as a reasonable forecast of anticipated damages due to delay, but rather solely as a penalty to discourage breach (delay). That the sum was chosen to insure “adherence” with the schedule, that appellee would construe it to apply even on days that the store ordinarily was closed for business, and that appellee repeatedly referred to, and contended that, the stipulation was a “penalty,” clearly forecloses any claim that it was intended as a measure of compensation. Accordingly, we reverse and vacate the award of $22,000 finding the [591]*591liquidated damages stipulation penal in nature and unenforceable on grounds of public policy.6
LOST PROFITS AWARD
In addition to liquidated damages, appellee recovered $53,716 in lost profits damages for breach of commercial lease. At trial, appellant’s attorney responded to appellee’s claim for loss of profits damages suggesting the existence of a variance between the allegata and the probata:
It is further contended by the plaintiffs that they are entitled to lost profits other than the stipulated damage calculation in the amendment to the lease. In fact, that is not pleaded in this complaint in equity. It’s our conten[592]*592tion that this case for money damages is limited solely to the five hundred dollar a day liquidated damages clause.
N.T. February 23, 1988, at 7. Later on at trial, appellant’s attorney twice made similar objections:
Objection, your honor. For the record, I’m objecting to any introduction of any damages other than damages flowing from the five hundred dollar a day contract.
There is no claim for lost profits in the complaint or any other pleading. I don’t know how I can respond to something that is not pled.
N.T. February 23, 1988, at 103, 182.
Appellant properly preserved in post-trial motions the issue of variance from the pleadings. See Motion for Post-Trial Relief at 2, and Memorandum in support thereof at 2. Clearly, appellant could have done no more to apprise the chancellor of the purported variance. Cf. Ingrassia Const. Co., Inc. v. Walsh, 337 Pa.Super. 58, 486 A.2d 478, 481 (1984), (failure to object to variance at trial is a waiver of the right to object to it thereafter); see generally 6 Std.Pa. Pract. § 33:14 (1982) (describing particular time and place for objection on grounds of variance).
The general policy demanding consistency between the allegata and the probata derives from the belief that absent prior notice of what an opponent intends to prove at trial, a party may be surprised at trial and thereby deprived of the opportunity to prepare an adequate defense. See, e.g., Freer v. Parker, 411 Pa. 346, 192 A.2d 348, 349 (1963); Computer Print Systems, Inc. v. Lewis, 281 Pa.Super. 240, 422 A.2d 148, 152 (1980). This policy against prejudicial surprise is furthered substantially under the principles embodied in Pa.R.C.P. 1021 requiring, inter alia, that the relief to which a party deems himself entitled be specified in the pleadings, and, more particularly, that a demand for unliquidated damages be specifically pleaded.7
[593]*593Instantly, it is clear that these legal principles have been compromised sufficiently to warrant reversal of the lost profits award. Plaintiff-appellee pleaded only an action for breach of agreement and claimed relief only in the form of liquidated damages. See Complaint at note 4 supra. Nowhere in the pleadings is there a claimed breach of commercial lease in a more general sense upon which a lost profits award might have been granted, nor is there a claim for unliquidated damages, i.e., lost profits, in conformity with Rule 1021. We hold this to be a material variance from the pleadings and can find no indication from the pleadings or elsewhere to suggest that defendant-appellant had notice that such proof would be offered at trial. Accordingly, we reverse the chancellor and vacate the award for lost business profits.
Judgement reversed; the liquidated damages and lost profits awards are vacated.
