This case presents an issue of first impression: whether a guarantor or surety1 is released from his obligation when a creditor settles with and releases the primary obligor while specifically reserving its right of recourse against the guarantor. We hold that the guarantor is not released from his obligation.
William P. Hendershot was president, chief executive officer and majority shareholder of Mastercoach, Inc., a West Virginia corporation engaged in the business of van conversion. On January 14, 1985, Mastercoach entered into a written floor plan security agreement with the Charleston National Bank. The agreement provided Mastercoach with a one million dollar line of credit from the Bank for the purchase of inventory. Hendershot executed a sweeping guaranty agreement on the same day, promising to guarantee personally the performance of Mastercoach under the floor plan security agreement. See Appendix infra.
By signing the agreement, Hendershot agreed to “unconditionally guarantee prompt payment to Bank at maturity, whether by acceleration or otherwise, o[f] any note or other evidence of indebtedness] including interest thereon and all renewals, extensions, refinancings and modifications (including increases in the interest rate), thereof, in whole or in part, however changed in form, manner or amount arising out of the extension of credit.” He also “expressly waive[d] notice of and consented] to renewal, extension, refinancing and modification (including increases in the interest rate) of any note or other evidence of indebtedness secured” by the guaranty agreement.
About two months after the floor plan agreement and guaranty were executed, Mastercoach filed a petition for a Chapter 11 reorganization bankruptcy in the United States Bankruptcy Court for the Southern District of West Virginia. The case was converted to a Chapter 7 liquidation bankruptcy after Hendershot left his position at Mastercoach and moved to Indiana.
The Bank and the bankruptcy trustee for Mastercoach negotiated a compromise of their respective claims. The Bank’s letter offering compromise included the following language:
Such settlement will constitute full satisfaction of all claims of Charleston National Bank against Mastercoach, Inc. and you as Trustee of Mastercoach, Inc., and full satisfaction of all claims by you as Trustee of Mastercoach, Inc., and Mastercoach, Inc. against Charleston National Bank. Upon acceptance by you and the requisite approval by the appropriate court or courts, the parties will cause the above-captioned adversary proceedings to be dismissed with prejudice. Charleston National Bank hereby reserves its rights and recourse against William P. Hendershot as guarantor of the debt to the extent not paid in full pursuant to this agreement.
*548Record at 66 (emphasis added). The bankruptcy court accepted the compromise. The court’s order stated in pertinent part:
ORDERED, that the compromise between the Charleston National Bank and the Trustee as described in the letter agreements attached hereto as Exhibit A be and it hereby is approved; and it is FURTHER ORDERED, that the Trustee shall pay to Charleston National Bank $425,000 and Charleston National Bank shall accept $425,000 in full settlement of its $820,000 secured claim against the Debtor’s estate....
Record at 62. This order left the Bank with a $393,549.91 deficiency on the loan to Mastercoach.
The Bank then sued Hendershot in Indiana to recover the deficiency and accrued interest. After a bench trial, the trial court found that the compromise agreement did not release Hendershot from his obligation as guarantor and entered a judgment against him for $513,970 including interest. The Court of Appeals reversed, holding that “a surety is discharged from any further liability if the principal debtor is fully released by the creditor. An explicit reservation of rights by the creditor against the surety is ineffective when the creditor’s release of the principal cannot be characterized as merely a covenant not to sue the principal.” Hendershot v. Charleston National Bank (1989), Ind.App., 540 N.E.2d 615, 621. We grant transfer.
It is a sound and well-settled principal of law that sureties are not to be made liable beyond their contract and that any agreement with the creditor which varies essentially the terms of the contract without the assent of the surety will discharge the surety from responsibility. Lutz v. Frick Co. (1962), 242 Ind. 599, 181 N.E.2d 14.
Section 122 of the Restatement of Securities articulates a generally accepted exception to the rule:
Where the creditor releases a principal, the surety is discharged, unless
(a) the surety consents to remain liable not withstanding the release, or
(b) the creditor in the release reserves his rights against the surety.
Restatement of Securities § 122 (1941). If the creditor reserves his rights against the surety, the release of the principal will be construed as a covenant not to sue the principal. The creditor’s action will have the effect of notifying the principal that, in spite of the release, the surety may pay the debt and then come to him seeking reim-bursment. Restatement of Securities § 122 comment d.
Hendershot argues that this compromise agreement cannot be construed as a convenant not to sue because “the plain simple and ordinary interpretation of the words of [the Bank’s letter of] offer and the subsequent Order Approving Compromise by the bankruptcy court are a final and complete release of the principal debtor upon the receipt of ‘full satisfaction’ of the creditor’s claims.” Appellant’s Brief in Opposition to Transfer at 5. The Court of Appeals, relying on the Ohio case of Gholson v. Savin2, agreed with Hendershot saying:
The court in Gholson recognized that when the creditor fully settles his rights with the debtor, no rights have been preserved for the surety to assume. When a settlement is not merely a convenant not to sue, but a final release of the creditor’s rights, the reasoning in support of the exception [articulated in § 122(b)] has no vitality. The surety is impaired because he has no subrogated rights preserved with which to pursue the principal debtor, if there is a final and full release. The reservation under *549such circumstances does not prevent the surety from being discharged.
Hendershot, 540 N.E.2d at 619.
We believe that focusing on words like “full satisfaction” and “final release” in an agreement between creditor and debt- or wrongly ignores the reservation of rights against the surety. When the creditor clearly reserves his rights against the surety, the debtor is notified that the release is no more than a covenant not to sue. Consequently, the principal debt remains alive, the surety’s rights to reimbursment and subrogation are unimpaired, and the surety is not discharged. Warner Lambert Pharmaceutical Company v. Sylk, 348 F.Supp. 1039, 1044-45 (E.D.Pa.1971); 10 S. Williston, A Treatise on the Law of Contracts § 1230 (3rd ed. 1967).
The Bank explicitly reserved its rights against Hendershot in its offer to compromise. The letter containing this offer was incorporated into the compromise agreement. Hendershot’s legal rights to reimbursement and subrogation were not impaired by the agreement, and he is not discharged.
We vacate the opinion of the Court of Appeals and affirm the judgment of the trial court.

. 137 Ohio St. 551, 31 N.E.2d 858 (1941). Gholson was litigated before the Restatement of Securities was adopted. As far as we can tell, the intervening half century of caselaw has followed the Restatement and not Gholson. See, e.g., Security Nat’l Bank v. Continental Ins. Co., 586 F.Supp. 139 (D.Kan.1982); Warner Lambert Pharmaceutical Co. v. Sylk, 348 F.Supp. 1039 (E.D.Pa.1971), aff'd without opinion, 475 F.2d 1398 (3rd Cir.1973); Continential Bank & Trust Co. v.
