OPINION OF THE COURT.
The appellee, P. F. McDonald, in September, 1915, was in the employ of tbe Stockmen’s Guaranty Loan Company of Albuquerque, N. M., as an agent for tbe sale of its stock under an agreement with the company by which he was to receive, as Ms compensation for stock sold by him, 20 per cent, of the sale price. On the 24th day of September, 1915, tbe appellee procured the appellant Leopoldo Mazon, as a purchaser of 5,000 shares of said stock at and for the price of $2 per share, and at the same time Mazon executed the ■ following written subscription:
“Agreement to purchase stock of Stockmen’s Guaranty Loan) Co. Capital stock $500,000.00.
“To Root & Chase, Fiscal Agents:
“I, L. Mazon, of Albuquerque, do hereby apply for 5,000 shares of the fully paid and non-assessahle capital stock of the Stockmen’s Guaranty Loan Company of Albuquerque, New Mexico, and agree to pay therefor two dollars per share as follows: $2,500, cash, receipt whereof is hereby acknowl-
edged, and note for $7,500 due in twelve months after date. The stock herein subscribed for shall he held by thei Stock-men’s Guaranty Loan' Company as collateral security and delivered when fully paid for in cash.
“Dated and signed this 24th day of Sept., 1915.
Leopoldo Mazon, Subscriber.
“D. F. McDonald, Agent.”
Mazon, in discharge of his obligation under said subscription, exeented and delivered three promissory notes aggregating $10,000, one of said notes being for $7,500, payable to tbe Stockmen’s Guaranty Loan Company, due 12 months after date, two notes in favor of and indorsed by himself in blank, one of which was for the sum of $2,000 and tbe other $500. In pa3un'ent of the appellee’s commission earned in said" transaction, the Stockmen’s Guaranty Loan Company delivered to him the note for $2,000, above mentioned, due 6 months after date, which is the note sued on herein.
On the 30th day of November, 1915, tlie corporation issued a certificate, No. 75, for 5,000 shares of said stock *442to appellant Mazon, but retained. the stock as security for the payment of the note of $7,500 in favor of the company, executed by Mazon in partial discharge of his obligation under his subscription contract. The complaint alleged that on the 18th day of November, 1915, appellant Mazon transferred all his property to his ooappellant, Mazon Estate, Incorporated, and that as a part of the consideration for that transfer the Mazon Estate, Incorporated, assumed the payment of all the debts of the defendant Leopoldo Mazon.
The answer of appellant Leopoldo Mazon was, in substance, as follows: First, he admitted the execution and delivery of the note sued on; second, he alleged that the sole and only consideration for the execution and delivery of the note was in part payment of certain shares of stock in the Stockmen’s Guaranty Loan Company; third, he denied that the} note was acquired' by appellee in due course before maturity for a valuable consideration; and, fourth, alleged that he had received no shares of stock in said company and that by reason of such fact there was and has been no consideration whatever for said note, of which fact the appellee was alleged to have had full knowledge. Issue was joined on the allegations of the answer.
The only issue raised by.the answer of the Mazon Estate, Incorporated, was by its denial of the allegations of the complaint to tine effect that Leopoldo Mazon had transferred all his property to said corporation, and that as a part of the consideration therefor the corporation assumed the payment of all the debts of the defendant Leopoldo Mazon. The issues were thus presented to the lower court for determination, namely: Frst, whether the appellant Mazon received any consideration for the execution and delivery of the note sued on; second, whether the Mazon Estate, Incorporated, assumed the payment of the debts of the defendant Leopoldo Mazon, including the debt evidenced by the note in this case. The court found both issues in favor of the appellee and rendered judgment accordingly, from which this appeal is prosecuted.
[1] The first point upon which appellants rely for a reversal is that the appellee was not a transferee in duo *443course of the note in question, nor was the note supported by any consideration. As shown in the third paragraph of the answer of Leopoldo Mazon, he admitted that he executed said note in part payment for certain shares of stock in the Stockman’s Guaranty Loan Company; but in the fifth paragraph he alleged that he had received no shares of stock in said company, by reason of which there had been no consideration, and that if there was an apparent consideration it had failed by reason of the fact that no such stock had been issued and delivered to him. The evidence clearly shows that the note in questif n was executed in part payment of the subscription which appellant Mazon had made to the capital stock of the company, and it is likewise clearly shown that in pursuance of such subscription a certificate for 5,000 shares of the stock of the company was issued to Mr. Mazon on the 30th day of November, 1915; the original certificate being produced and introduced in evidence. Mazon bargained for 5,000 shares oJ; stock, for which he agreed to pay $10,000, and as evidence of his indebtedness he executed and delivered the three promissory notes mentioned, aggregating that amount. By so doing he acquired'the right to have the stock for which he bargained issued to, him, and it was issued and ready for delivery upon the payment of the balance of $7,-500 due thereon for which the stock was held as collateral securit3r. The company, under the subscription agreement, had the right to hold the stock as security. The fact that the company saw fit to pay the agent a commission of 20 per cent, for making the sale, and that the agent was contented to take the note for $2,000 in payment of his commission, in lieu of cash, is a matter between the company and appellee, and we fail to see how it alters the fact that Mazon bought 5,000 shares of the stock for which he agreed to pay $10,000; neither does it alter or affect the right of the parties that the salesman knew, at the time of the execution of the note, that he was to take the $2,000 note in payment of his commission. The note being supported by a valid consideration, the question as to- whether the appellee was a trans*444feree in clue course is immaterial under the issues raised by the pleadings.
It is next contended that there was no assumption of the debt in question by the appellant Mazon Estate, Incorporated. Ilpon the trial appellee called O. N. Marrón as a witness. Marrón testified that he was president of the Mazon Estate, Incorporated, in November, 1915, and identified the minutes of the meeting of the board of directors held on the 18th day of that month, which were marked “Exhibit A.” These minutes recite, -in so far as materia], as follows:
“The president them presented the written proposal of Leopoldo Mazon, Jr., and Luz Mazon to assign to the company all the property, real and personal, from them by or through the Leopoldo Mazon Estate as more particularly appears in said proposition which was ordered spread upon the minutes and is as follows: ‘To the Officers and Directors of the Mazon Estate, Incorporated: We hereby offer to convey to the Mazon Estate, Incorporated, all our right,, title and interest in the lands, stock and personal property now owned by us and which belonged to Leopoldo Mazon in his lifetime in exchange for the entire capital stock of the company, same to be issued to' us as fully paid stock. The property to be conveyed to be all of the real estate formerly belonging to the said Leopoldo Mazon, whether the same were his individual property or community property. Dated this 18th day of November, 1915. Luz C. Mazon. Leopoldo Mazoni, Jr.’
“The president also presented a resolution of the stockholders approving said proposal and authorizing and instructing the directors to accept the same and take such action in regard thereto as may be necessary. *
“The following resolution was thereupon moved, seconded, and unanimously adopted: ‘Whereas, the property offered in exchange for the entire capital stock of this company by Leopoldo Mazon, Jr., and Luz C. Mazon, in their proposition to this company is adjudged by this board to be reasonably worth the par value of the shares of stock so proposed for over and above all the debts of the said Luz C. Mazon and Leopoldo Mazon, Jr., which are to be assumed by the company and said property to be necessary for the use and lawful purpose of this company.’ ”
[2] Appellants contend that the minutes of the meeting of the board of directors were never introduced in evidence, and it must be admitted that, while the minutes are incorporated in the bill of exceptions under “Exhibit A,” it does not show that such exhibit was ever formally introduced in evidence. The transcript of the stenograph*445er’s notes, together with copies of all exhibits, including Exhibit A, was, upon motion bjr attorneys for appellants, certified by the court as bill of exceptions in the case, and certainly without the exhibit having been considered by the trial court judgment would not have been rendered for appellee. The exhibit is referred to in the abstract of the record prepared by appellants, and apparently in their brief for the first time, the suggestion was made that this exhibit had not been introduced in evidence. This) question is disposed of by the case of Finnerty v. Stratton’s Estate, 123 Pac. 677, where it is said:
“The record discloses that the written, instruments considered were treated by both counsel and court as having been introduced in evidence. In such circumstances neither party will be heard to say, on review, that they were not, even, though the record fails to disclose a formal Introduction. It was upon the strength of these writing that counsel for the estate objected to the oral testimony excluded. Obviously they must have been regarded as introduced in evidence; otherwise there was no basis for the objection.
We conclude that where both parties upon the trial treat an exhibit as having been introdriced in evidence and upon the facts shown by such exhibit judgment is rendered by the trial court and without such exhibit such judgment could not have been rendered, neither party can, on appeal, contend that such exhibit was not introduced in evidence.
[3] It is contended by appellee that the proposition made to the corporation, Mazon Estate, Incorporated, by the Mazons, accepted by the resolution heretofore quoted, constituted a contract between Leopoldo Mazon and the corporation by which it undertook to pay all the debts which he then owed; that the contract was made for the benefit of his creditors, one of which the appellee was at that time. On the other hand, it is contended by the appellant that the resolution did not amount to an agreement on the part of the corporation to pay the debt in question, and the evidence of ML Marrom who was president of the corporation at the time the stock was exchanged for the property of the Mazons, sheds no light upon the matter. The witness stated that it was the understanding *446that two of the debt of Leopoldo Mazon should be paid, but he was not asked as to what those debts were, and there is no evidence to show that the note in question was one of such debts. It is to be noted that, although the alleged resolution does set forth, by way of recitation, that the property offered to the corporation by Luz C. Mazon and Leopoldo Mazoñ was adjudged by the board of directors to be worth the par value of the stock to be exchanged therefor, over and above all the debts which were to be assumed bjr the company, still there is no recital as to what debts the company was assuming and undertaking to pay. In the proposition referred to, heretofore set out in this opinion, it will be noted that it does not contain any recital as to an assumption by the corporation of any of the debts of Luz C. Mazon and Leopoldo Mazon. The resolution does not state that the corporation does assume the debts .of Luz C. Mazon and Leopoldo Mazon, or that it has assumed them, but merely states that the property is worth the par value of the stock over and above all the debts of said Luz C. Mazon and Leopoldo Mazon, which are to be assumed by the company. What specific debts will constitute all those which are to be assumed ? When' and under what circumstances will that assumption take place ? On these important qiiestions the resolution is silent. Where a party claims rights under a written contract, or agreement represented by separate writings, and the language' of the contract, upon which his rights depend, is ambiguous or uncertain, the burden is upon such party to introduce evidence to explain the ambiguity and to show by extrinsic evidence that the right he claims is conferred upon him by the contract. In Elliott on Contracts, § 1655, it is said:
“Parol evidence is admissible, in the construction of contracts, to_ define the nature and qualities of the sub-ject-matter, the situation and relations of the parties, and all the circumstances, inj order that the courts may put themselves in the place of the parties, see how the terms of the instrument affect the subject-matter, and ascertain the signification which ought to be given to any phrase or term in the contract which is ambiguous or susceptible of .more than one interprettion; and this, although the result of the evidence may be to contradict the usual meaning of the terms and *447phrases used in the contract; but if the words are clear and unambiguous, a contrary contention may not be derived from the circumstances!’
If it be assumed that the language used in the resolution was simply ambiguous and might have been explained by paro'l evidence, nevertheless the evidence offered by appellee failed to give meaning to the language or to explain away the ambiguity. Tbe burden ivas upon the appellee to establish the fact that the corporation had assumed the payment of this particular debt. This burden he failed to meet, and for this reason the trial court, was in error in awarding judgment against the Mazon Estate, Incorporated. There was no error in giving appellee judgment against appellant Leopoldo Mazon, as the facts clearly establish his individual liability on tbe note.
For these reasons the judgment will be affirmed as to Leopoldo Mazon and reversed as to tbe Mazon Estate, Incorporated, with instruction to the trial court to enter judgment in favor of said corporation; and it is so ordered.
