¶1Suit upon a promissory note for 2,000 dollars, dated October 13, 1855, given by C. H. Brown, with G. Zimmerman as surety, to Samuel Judah, payable one day after date.
¶2It appears by the answer of the defendant, Zimmermcm, that at the same time that this note was executed, Judah and Brown entered into a contract, by which Brown was to erect for Judah a certain building, to be wholly completed ready for occupancy by the first day of November, 1856. The agreement fixes the amount to be paid, the *287time of payment, &c. The last clause of the agreement is as follows:
“5th. As to the balance, 2,000 dollars, it is agreed as follows: Said Judah herewith advances to said Brown, as and for a loan on a note payable one day after date, the said sum of 2,000 dollars, which note shall be satisfied by the completion of said building as in this contract is provided; and which note, also, shall not become or be payable so long as said Brown shall progress with the preparation of materials, and with the erection of said building, so as to warrant the said superintendent in the reasonable expectation of the progress and completion of the work, as is hereinbefore provided. October 13, 1855.
[Signed “ Charles H. Brown,
“ C. Zimmerman (surety),
“ Samuel Judah.”
¶3It thus appears that the 2,000 dollars specified in the note sued on was substantially a penalty. If the building was proceeded with and completed according to contract, the 2,000 dollar note was never to be paid. If not, it was to be paid.
¶4The answer further shows, that on the 5th day of June, 1856, the following further agreement was made without the knowledge or consent of Zimmerman, viz.: That said Brown and one Stokes should, by the 1st day of November, 1856, put an additional story on the building then under contract between Brown and Judah, for the further consideration of 1,700 dollars, to be paid on the completion thereof.
¶5The answer claims that this agreement was such an alteration of the original agreement, as discharged Zimmerman, the surety.
¶6The plaintiff demurred to the answer; the Court sustained the demurrer, and the plaintiff had judgment.
¶7The record discloses nothing by which we can determine whether the contracts for erecting the building were fulfilled or not. The inference from this second contract is, that the execution of the first had satisfactorily progressed up to the 5th of June, 1856. And there is another letter *288from Mr. Judah, set out in the answer, dated September 10, 1853, which admits due exertion on the part of Brown in the execution of his undertakings. But the decision of the case here, must rest on the single point, as to whether the second contract above set out was such an alteration of the first as to discharge the surety for the performance of it; and we thus conclude:
¶8The second contract required an additional story to be put upon the building. The building could not be finished under the first contract until after that story was put on, as it could not, till after that, be roofed. That contract did, therefore, increase the difficulty and expense of, and tend to delay the completion of, the first contract, and did, therefore, materially affect its execution, though it states that it is not to do so. It, in fact, made Zimmerman surety for the completion by the 1st of November, 1856, of the walls of the additional story provided for by the second contract. See Chit, on Cont., 529, 530; Ind. Dig. 703.
¶9The judgment is reversed with costs.
¶10Cause remanded, &c.
