OPINION
BURKE, Justice.This case presents the question of whether a stipulation to dismiss with prejudice certain misrepresentation claims precludes a foreclosure on real property when the underlying claims arose from the same transaction. Superior Court Judge Joan M. Katz concluded that the doctrine of res judicata barred the instant nonjudicial foreclosure, and granted plaintiffs summary judgment motion. We affirm.
I. FACTUAL AND PROCEDURAL BACKGROUND
In 1978, Vance Tolstrup and Michael Huffman were involved in a small computer business called Data-Com Systems, Inc. In June 1978, Huffman arranged for an $80,000 loan from Alaska National Bank of the North (ANBN) for Data-Com. Tolstr-up was reluctant to sign the note as a personal co-surety. To protect himself in case he was required to fulfill his guaranty and pay on the note, Tolstrup sought security from Huffman. Huffman pledged to partially indemnify Tolstrup in case Tolstr-up had to pay ANBN on the guarantee.1 Huffman also executed a deed of trust on real property that Huffman owned in Anchor Point, Alaska, in favor of Tolstrup. With this collateral, Tolstrup signed as one of the personal guarantors for the ANBN loan.2 Tolstrup subsequently paid substantial amounts of money to ANBN on his guarantee. In February 1979, the personal and financial problems of Data-Com caused the corporation to close.
In 1979, Huffman filed a third-party complaint against Tolstrup3 alleging unlawful activity in connection with their corporation. In 1982, Tolstrup counterclaimed, alleging that Huffman fraudulently induced him to guarantee the $80,000 loan by misrepresenting the value of the property offered as security. Tolstrup concluded “[a]s a result of the foregoing, defendant has been damaged in the amount of $80,000 *1306plus interest and has been forced to pay approximately $30,000 in repayment.”
In November 1982, Huffman and Tolstr-up agreed to dismiss their claims and counterclaims with prejudice. Their stipulation specifically included a dismissal of Tolstr-up’s counterclaim against Huffman, but the parties disagree about exactly which claims were extinguished.
By August 1983, Tolstrup had paid approximately $34,000 to ANBN for the 1978 loan which he had guaranteed. Huffman had defaulted on his agreement to indemnify Tolstrup.4 Under the terms of the deed of trust, Tolstrup then began a nonjudicial foreclosure on the secured property.5 At that time, the property was owned by plaintiffs Miller, Burkhart, and Osborn (collectively referred to as Miller). They had purchased various ownership rights from Huffman in late 1978, between the time of the loan transaction and Data-Com’s collapse.
Miller sought to enjoin the foreclosure. In her motion for summary judgment, Miller asserted that the 1982 stipulation dismissing Tolstrup’s counterclaims against Huffman barred Tolstrup’s foreclosure action. The superior court granted the summary judgment motion, concluding that the 1982 stipulation involved the identical transaction and that res judicata, thus, precluded the foreclosure. We agree.
II. DISCUSSION
A. Res Judicata
Tolstrup contends that the claim dismissed by the stipulation was for the tort of fraud, while the present foreclosure is based on Huffman’s default on the indemnity agreement. Therefore, he argues, res judicata does not apply and the foreclosure is not barred as a matter of law. Miller, however, argues that res judicata precludes Tolstrup’s foreclosure because it is based on either the same claim or one which could have been raised in the earlier lawsuit between Huffman and Tolstrup.
A stipulation to dismiss claims with prejudice operates as an adjudication upon the merits. Civil Rule 41(a)(1). Other jurisdictions have held that such a stipulation is just as valid as a final judgment resulting from a trial on the merits, and is res judicata as to all issues that were raised or could have been determined under the pleadings. Suttle v. Seely, 94 Ariz. 161, 382 P.2d 570, 572 (App.1963); Bank of America v. Department of Mental Hygiene, 246 Cal.App.2d 578, 54 Cal.Rptr. 899, 903 (1967).6 We agree and hold that the dismissal here had the same res judicata effect as a final judgment after trial.
Under the doctrine of res judica-ta, a final judgment bars a subsequent suit, between the same parties or their privies, upon the same claim or demand. Calhoun v. Greening, 636 P.2d 69, 71-72 (Alaska 1981); Moran v. Poland, 494 P.2d 814, 815 (Alaska 1972). A final judgment extinguishes all claims “with respect to all or any part of the transaction, or series of connected transactions” out of which the previous action arose. Restatement (Second) of Judgments § 24 (1982). In addition, res judicata bars a second suit when the matter therein could have been decided in the first suit. Pankratz v. State, De*1307partment of Highways, 652 P.2d 68, 74 (Alaska 1982).
To decide whether res judicata precludes Tolstrup’s foreclosure, we must determine whether the underlying claim is the same as, or transactionally connected with, the claim extinguished by stipulation in the earlier lawsuit. Tolstrup’s original counterclaim alleged that Huffman misrepresented the value of the secured property, thereby fraudulently inducing him to accept the deed of trust as collateral and co-sign the ANBN loan. Tolstrup sought $80,000 in damages, which was also the principal amount of the ANBN loan. This claim, although pled in tort, concerns the circumstances surrounding the signing of the guaranty. Tolstrup argues that the present foreclosure is based not upon fraud and misrepresentation, but upon Huffman’s default on the indemnity agreement contained in the deed of trust. He contends, therefore, that this is wholly separate from the previous suit.
A mere change in the legal theory is not sufficient to prevent the operation of res judicata. Pankratz, 652 P.2d at 74. We conclude that both the counterclaim for fraud and the nonjudicial foreclosure arose from the same transaction: Huffman’s inducements for Tolstrup’s co-signing on the $80,000 loan. Characterizing the first clai-ma s a tort and the second as a default will not avoid the effects of res judicata when the underlying claims are part of the same transaction. Tolstrup could have, and should have, joined a claim for default damages or judicial foreclosure to his 1982 counterclaim to Huffman’s third-party action against him. The dismissal of the counterclaim waived Tolstrup’s right to proceed later against the deed of trust for the default. The claim for default was part of the same transaction as the prior counterclaim, and he cannot now revive that extinguished claim.7
We agree with the superior court that Tolstrup’s foreclosure action is barred under the general rules of res judicata. First, as a subsequent purchaser of an interest in the property, Miller is in privity with Huffman.8 Second, the stipulation of dismissal with prejudice is a final judgment on the merits for purposes of res judicata. Third, both the dismissed counterclaim and the foreclosure action involve the same transaction, despite the change in legal theory.
B. Attorney’s Fees
Tolstrup argues that the trial court’s award of $5,000 in attorney’s fees to Miller is excessive in light of the limited time spent on the case. Miller contends that $5,000 is a reasonable amount since it complies with the rate schedule set out in Civil Rule 82(a)(1).9
Rule 82(a)(1) grants the trial court discretion to award fees in a reasonable amount. We will not reverse an award of attorney’s fees “unless manifestly unreasonable, arbitrary or designed for a purpose other than justly deserved compensation.” Fairbanks Builders v. Sandstrom Plumbing & Heating, 555 P.2d 964, 966-67 (Alaska 1976) (footnotes omitted). The trial court based the award on the *1308potential liability of $57,000, the amount by which Huffman was in default. $5,000 coincides with the fee schedule in Civil Rule 82(a)(1) for a case “without trial.” There is no evidence that this award of attorney’s fees was manifestly unreasonable. The trial court did not abuse its discretion.
We AFFIRM the grant of summary judgment and the award of attorney’s fees.
.The obligation secured by the deed essentially provided that if Tolstrup became obligated to pay ANBN on his guarantee, Huffman would pay him two-thirds of any amount Tolstrup paid in excess of what Huffman himself might pay as a co-guarantor.
. Tolstrup was one of four co-sureties on this loan; two other officers and Huffman also signed.
. The third-party complaint was filed in a case which Alaska Pacific Bank instituted against Huffman to recover other Data-Com debts.
. Huffman had neither paid ANBN in his capacity as guarantor, nor had he paid Tolstrup according to the terms of the deed of trust. Huffman was in default already at the time of Tolstr-up’s 1982 counterclaim. He remained in default after the stipulated dismissal.
. Tolstrup filed and recorded a notice of default against the property. The notice stated that it would be sold at a public auction unless Huffman paid him $23,000 plus interest and costs. This is two-thirds of the amount that Tolstrup paid to ANBN.
.See also 47 Am.Jur.2d Judgments § 1095 (1967) (a stipulation of dismissal amounts to a decision on the merits barring further litigation on the same subject matter between the parties); Annot., 91 A.L.R.3d 1170 (1979).
.We reach our result solely on the points presented in the parties’ briefs and oral arguments. We do not review points neither raised below nor included in the points on appeal. Saxton v. Splettstoezer, 557 P.2d 1126, 1127 (Alaska 1977). Thus, we express no opinion on whether claim preclusion in general applies to nonjudicial remedies.
We further note that nothing in our decision today would prevent a party to a settlement from expressly reserving a right to foreclose nonjudicially. Such reservation could appear in the stipulated dismissal or in a separately executed settlement agreement. The record here, however, reveals no such reservation.
. Although the three appellees purchased different interests in the property, each is in privity with Huffman as a successor in interest.
. Civil Rule 82 sets out a schedule for computing attorney's fees in average cases according to whether the case was "contested,” "without trial," or "non-contested.”
