EMRO Marketing Company (EMRO) appeals from a final judgment entered in the District Court for the Eastern District of Missouri terminating a lease between EMRO, as lessee, and William Niles Plem-mons (Plemmons), as lessor, due to the breach by EMRO of an implied covenant of continuous operation. For reversal, EMRO argues the district court1 erred in (1) implying a covenant of continuous operation, and (2) refusing to excuse EMRO’s non-performance of the implied covenant due to provisions of the Bankruptcy Code. For the reasons discussed below, we affirm.
BACKGROUND
This appeal involves a suit by EMRO, as lessee, for a declaratory judgment and in-junctive relief regarding the status of a lease of real property. Plemmons owns the property in question, which is located in St. James, Missouri. Greta L. Plemmons, his sister and predecessor in interest, entered into a lease agreement concerning *529the property dated December 13,1966, with EMRO’s predecessor in interest, Nickerson & Nickerson, Inc. (Nickerson). The lease provides for a primary lease term to and including June 1, 1987, and thereafter, at lessee’s option, for six successive renewal lease periods of six years each. The lease also grants the lessee an option to purchase the property for $30,000.00.
The original lessee, Nickerson, intended to use the premises to operate a Nickerson Farms store. The “use” clause of the lease sets forth this intention:
The leased premises are to be used as a site for a Nickerson Farms Store for the sale of food, gifts, candy, petroleum products and other merchandise customarily handled by such stores; and for the conduct of any lawful business; and the Lessee is hereby given the right to sublease or underlet said premises or to assign the whole or any part of the term of this lease.
The lease also provides the lessee the right to remove buildings and other property placed on the premises by the lessee.
Lessee shall, without any obligation or liability whatsoever, have the right, at any time during the continuance, or within thirty days after termination of this lease, or any renewal or extension thereof, either to remove from, or leave upon, the leased premises any, all or any part or parts of any and all buildings, fixtures, equipment and other property owned by Lessee or placed on the leased premises by Lessee during the term of, or any renewal or extension of, this or any previous lease.
The rental term of the lease provides: As rental for this Lease, Lessee agrees to pay One Hundred and no/100 dollars ($100.00) per month on the first day of each month in advance, to Lessor unless otherwise provided herein, and also pay gallonage rental of V2 (one-half cents) per gallon on gasoline sales made by lessee at its Nickerson Farms Store to be located on the premises * * *.
Shortly after executing the lease, Nicker-son constructed a Nickerson Farms store on the premises. Nickerson later assigned the lease to EMRO, who in turn sublet the premises to o.g.y., Inc. (o.g.y.), which then operated on the premises a gas station and store-restaurant similar to the Nickerson Farms operation. O.g.y. subsequently entered bankruptcy reorganization proceedings and ceased business operations on the premises in December of 1984. Since that time EMRO has continued to pay the base monthly rental of one hundred dollars per month to Plemmons. No gallonage rental has been paid during this period, however, because no gasoline retail sales have been made on the premises.
On January 14, 1985, EMRO filed a compliant in the District Court for the Northern District of Illinois alleging that o.g.y. was in default on the sub-lease and seeking to obtain possession of the premises. While that case was pending, o.g.y. filed, on September 23, 1985, a Chapter 11 petition in the Bankruptcy Court for the Northern District of Illinois.
In the midst of the Illinois litigation, Plemmons, on April 1, 1986, informed EMRO that he considered EMRO to be in violation of the lease because of the failure to operate a Nickerson Farms store on the premises and the resultant failure to pay monthly gallonage rentals. EMRO then filed this action for declaratory relief to establish that no breach of the lease had occurred. Plemmons counterclaimed, seeking a declaratory judgment that the lease had been terminated and requesting possession of the premises.
The district court conducted a bench trial on December 17, 1986, and entered judgment in favor of Plemmons on January 14, 1987. The district court found an implied covenant by the lessee to continue the operation of a business generating gasoline sales throughout the term of the lease. Finding a breach of this implied covenant, the district court ordered that the lease be terminated as of April 1,1986. This appeal followed.
DISCUSSION
We consider first EMRO’s argument that the district court erred in finding an implied covenant by the lessee to contin*530ue the operation of a business generating gasoline sales throughout the term of the lease. The parties agree that Missouri law must govern the resolution of this issue.2
We believe the district court correctly found that the provisions of this lease support an implied covenant of continuous operation. The “use” term of the lease is restrictive in nature — it expressly restricts the lessee’s use of the premises to a site for a Nickerson Farms store. Further, the price term of the lease contemplates payment, in significant part, in the form of gallonage rental, which could only be collected if such a business was operating on the premises. A reading of the contract as a whole, we believe, supports the district court’s conclusion that the parties contemplated a specific and exclusive use of the property.
The lease provisions relied upon by EMRO do not alter this conclusion. The right to sublease, underlease or assign for all or part of the duration of the lease does not support the contention that continuous petroleum sales were not contemplated by the contracting parties. The case cited by EMRO, Crestwood Plaza, Inc. v. Kroger Co., 520 S.W.2d 93 (Mo.App.1974), for the proposition that a subletting provision abrogates a retail percentage as a source of rent is not apposite to this action. Assuming, for the sake of argument, the absence of the requirement in this lease that the “premises are to be used for a Nickerson Farms store for the sale of * * * petroleum products,” the key ingredient in the Crestwood Plaza analysis is “a substantial guaranteed rent.” Id. at 97. Here we do not have that. The guaranteed rent is $100.00 per month. The value of the property at the time the lease was entered into was at least $30,000.00 as determined by the parties. Even though the lessee was to pay the general and special tax assessments, $100.00 per month for a $30,000.00 commercial property cannot be considered “substantial guaranteed rent.”
Likewise, the improvements removal clause is merely a severance provision which permits the lessee to remove buildings, fixtures and other improvements which would ordinarily become the property of the fee holder upon completion of the term of the lease. The contract language simply permits Nickerson or its assigns to determine whether it is economically feasible to remove the improvements or to leave them for the landowner to contend with. It is likely that every well drafted retail gasoline lease in force in America contains such a clause, intended for the purpose stated above. Its presence in this lease is not relevant to the existence of an implied covenant of continuing petroleum product sales.
Simply stated, we agree with the district court that the agreement contemplated an implied covenant of petroleum product sales. The district court was correct in this analysis.
The alternative contention of EMRO, that it has been precluded by bankruptcy law from fulfilling the implied cove' nant, is more problematic. Clearly, EMRO was permitted to sublease. Thus, it should not be penalized for matters beyond its control, for instance, the inability to repossess the leased premises because of bankruptcy law. See 11 U.S.C. §§ 362(a)(1), (3). EMRO had a duty, however, to move expe=. ditiously to seek to lift any stay which precluded repossession. Additionally, in this case it appears that EMRO did not effectively pursue repossession for almost seven months prior to being stayed by the bankruptcy filing.3 - EMRO is not entitled to cure its breach of the implied covenant *531after such a period of time. It may not rely upon these circumstances to support an impossibility defense in this case.
CONCLUSION
The decision of the district court is affirmed.
. The Honorable William L. Hungate, United States District Judge for the Eastern District of Missouri.
. As noted, the lease agreement was prepared by Nickerson, EMRO's predecessor in interest. In fact, the contract consists of a printed form, l-NF-3/66, which form was probably used, with individualized insertions, for all of Nicker-son’s leased business sites. Thus, ambiguities, if any, must be construed against EMRO, as the successor of the drafter of the instrument. Keith v. Tucker, 483 S.W.2d 430, 434 (Mo.App.1972).
. Apparently the subtenant business closed in November 1984 and the sublessee filed for bankruptcy on September 23, 1985. EMRO filed suit on January 14, 1985, after giving notice of breach of the sublease and an opportunity to cure. The stay was not imposed until approximately seven months later.
