hThe plaintiff, Hercules Offshore, Inc. (Hercules), appeals the trial court’s denial of its motion to vacate an order of dismissal finding that Hercules had abandoned its suit for refund against the Lafayette Parish School Board, Sales and Use Tax Department (Department). Finding no manifest error on the part of the trial court in denying Hercules’ motion to vacate, we affirm.
I.
ISSUES
We must decide whether the trial court manifestly erred in denying Hercules’ motion to vacate the court’s order dismissing Hercules’ suit under the law on abandonment.
II.
FACTS AND PROCEDURAL HISTORY
Hercules received a 2004 tax assessment from the Department for unpaid sales and use taxes for 1998 through 2001. Hercules paid the total amount due, $839,698.74 ($192,513.44 — taxes + $99,056.94 — interest + $48,128.36 — penalty) under protest and filed suit on December 5, 2007, for a rede-termination and refund of the taxes.
In November, 2013, the Department’s Collector filed a motion to dismiss Hercules’ suit due to abandonment, asserting that the last step in the litigation, under La.Code Civ. P. art. 561, occurred on September 1, 2009.
The trial court issued an order of dismissal. Hercules filed a motion to vacate the order of dismissal which was denied.

STANDARD OF REVIEW
An appellate court may not set aside a trial court’s findings of fact in absence of manifest error or unless it is clearly wrong. Stobart v. State, Through DOTD, 617 So.2d 880 (La.1993); Rosell v. ESCO, 549 So.2d 840 (La.1989). A two-tiered test must be applied in order to reverse the findings of the trial court. Mart v. Hill, 505 So.2d 1120 (La.1987). The appellate court must find from the record (1) that a reasonable factual basis does not exist for the finding of the trial court and (2) that the record establishes *1180that the finding is clearly wrong (manifestly erroneous). Id.

LAW AND DISCUSSION
At issue is whether Hercules’ 2007 suit to redetermine and refund the tax paid under protest was abandoned. Under La.Code Civ. P. art. 561, an action is abandoned “when the parties fail to take any step in its prosecution or defense in the trial court for a period of three years.” La.Code Civ. P. art. 561(A). A party takes a “step” in the prosecution or defense of a suit when he takes formal action, before the court, intended to hasten the matter to judgment. Chevron Oil Co. v. Traigle, 436 So.2d 530, 532 (La.1983). Formal discovery “served on all parties whether or not filed of record, including the taking of a deposition with or without formal notice, shall be deemed to be a step in the prosecution or defense of an action.” La.Code Civ. P. art. 561(B). Abandonment operates without a formal order, “but, on ex parte motion of any party or other interested person by affidavit which provides that no step has been timely taken in the prosecution or defense of lathe action, the trial court shall enter a formal order of dismissal as of the date of its abandonment.” La.Code Civ. P. art. 561(A)(3).
The Louisiana Supreme Court has interpreted Article 561 as imposing three requirements: (1) a party must take some step in the prosecution or defense of the litigation; (2) the step must be taken in the litigation and must appear in the record, with the exception of formal discovery; and (3) that step - must have been taken within three years of the last step taken by either the plaintiff or defendant. Clark v. State Farm Mut. Auto. Ins. Co., 00-3010 (La.5/15/01), 785 So.2d 779. The two jurisprudential exceptions are (1) a showing of contra non valentem by the plaintiff, or (2) waiver by the defendant.1 Id.
Here, Hercules filed its petition in December 2007.
The 2008 filings consisted of the defendant’s answer, reconventional demand, request for notice, and affidavit. The plaintiffs answer to the reconventional demand was also included.
In 2009, the plaintiff filed a motion to schedule a status conference, and the defendant filed a motion for summary judgment. The parties filed various supporting memoranda and continuances, and the trial court issued judgment in July, 2009, denying partial summary judgment to the defendants based upon issues of fact. The last filing was an August, 2009 order granting the plaintiff an extension of time to answer discovery. The defendants admit that the plaintiff answered discovery on September 1, 2009, which they assert was the last date of activity that qualifies as a step in the litigation under Article 561.
LNothing was filed in 2010 or in 2011. The only filing in 2012 was the June 19, 2012 request for notice filed by the plaintiff. Nothing was filed in 2013 until the defendant’s November 14, 2013 motion to dismiss due to abandonment.
A request for notice, such as that filed by Hercules on June 19, 2012, is not a step intended to hasten the matter to judgment; rather, it is a request for notification in the event that steps are taken. See *1181Haisty v. State, DOTD, 25,670 (La.App. 2 Cir. 3/30/94), 634 So.2d 919. A motion that grants counsel the right to take steps, or to prepare to take steps, toward the prosecution or defense of a case, but does not itself hasten the matter to judgment, is not an Article 561 step. See Chevron, 436 So.2d 530. Thus, where the last undisputed activity, Hercules’ response to formal discovery, was September 1, 2009, steps sufficient to interrupt abandonment had to have occurred by September 1, 2012.
Correspondence
Hercules submitted an affidavit attaching several e-mails dated in September, 2011, which indicate efforts to set up a settlement meeting for the following month. However, “ ‘[ejxtrajudicial efforts,’ such as informal settlement negotiations between the parties, have uniformly been held to be insufficient to constitute a step for purposes of interrupting abandonment.” Clark, 785 So.2d at 790. Correspondence evidencing even extensive settlement negotiations between the parties is deemed insufficient to interrupt abandonment. Chevron, 436 So.2d 530. The reasoning is that ongoing negotiations do not prevent counsel from taking formal action in the trial court within the intent of Article 561. Id.
Counsel for Hercules also attaches a two-paragraph letter from himself to the Tax Director of Hercules dated November 10, 2011, stating that the |sabove settlement meeting was held and that he disagreed with the outcome. Again under the reasoning of Chevron, the plaintiffs retain the ability to set the matter for trial if they feel the negotiations are not progressing satisfactorily. See Id.
A November 19, 2012 letter from Hercules counsel to the Collector is not a step because it concerns settlement discussions and because it is dated after the September 1, 2012 deadline signaling abandonment. This is also true of the letter from the Department’s counsel dated November 30, 2012, offering to settle the tax dispute in an amount that would refund Hercules $18,971.32.
Hercules asserts that verbal discussions and document retrieval was ongoing, and counsel submits an unsupported log of entries showing that some work, such as a phone call, a letter, or review of documents, was done in most months during the three-year period at issue.2 Hercules argues that these events show an intent not to abandon and asserts that the law changed in 2011, changing the traditional analysis “to review certain non-formal actions by Plaintiff as a ‘step’ in the prosecution of a claim.” This assertion is misplaced. Hercules cites La. DOTD v. Oilfield Heavy Haulers, L.L.C., 11-912 (La.12/6/11), 79 So.3d 978, which involved an action by the defendant. Hercules egregiously misquotes the case by stating that abandonment “must” be set aside, wherein Oilfield actually quotes Clark’s 2001 statement that abandonment “may” be set aside by showing a cause outside the record. See Oilfield, 79 So.3d at 985. In its block quote attributed to Oilfield, Hercules further inserts “Plaintiffs” in brackets next to a reference to “defendants” to enlarge the meaning of Oilfield when Oilfield clearly | ^applied its reasoning and Clark’s reasoning to actions by a “defendant” as the party whom the formal action requirement was designed to protect. See Id.
*1182Hercules further misinterprets Oilfield’s partial abrogation of Melancon, 307 So.2d 308, in support of its assertion that the law changed in 2011. This simply is not true. Oilfield in 2011 was not the first time the Louisiana Supreme Court criticized the language in Melancon, as it had previously done so in Clark in 2001, which referred to the court’s mistaken dicta in Melancon in 1975. Melancon, Chevron, Clark, and Oilfield all involved a defendant’s steps in the abandonment procedure, based upon the change in the law in 1960.
As explained in Clark, in 1960 the procedural rules on abandonment were transferred from La. Civ.Code art. 3519, which had addressed only the plaintiffs actions, to La.Code Civ. P. art. 561, which added (1) that abandonment is self-operative, and (2) that failure by the parties to take steps in the prosecution or defense of the suit leads to abandonment. The latter change was construed by Melancon “as codifying the defense-oriented waiver exception as a step in the defense.” Clark, 785 So.2d at 788. However, Melancon indicated that the defendant’s waiver had to incorporate formal action. Thus, the mistaken broad remark in Melancon was, “ ‘extrinsic proof of such a waiver cannot be permitted.’ ” Id. (quoting Melancon, 307 So.2d at 312). The 2001 Clark court made it clear that an unconditional tender of an undisputed amount was not a settlement negotiation, but was a defendant’s acknowledgement of liability to the plaintiff, which constituted waiver, which could be proved by extrinsic evidence.
In 2011, the Oilfield court quoted extensively from its 2001 decision in Clark, including Clark’s criticism of Melancon regarding extrinsic evidence of waiver, but it did not change the Clark analysis of the law. The Oilfield court |7found that, when the plaintiff failed to answer discovery timely, the defendant’s letter to all parties scheduling a mandatory discovery conference under Louisiana District Court Rule 10.1 constituted a step in the defense of the action because it hastened the matter to trial. Thus, a subsequent dismissal for abandonment obtained by the defendants was vacated when a defendant’s own action was found to have interrupted the abandonment period. Essentially, the Oilfield decision was about waiver, which has long been held an exception that could be proved by extrinsic evidence.
Only two categories of causes outside the record are permitted; namely, those causes falling within the two jurisprudential exceptions to the abandonment rule. Those two exceptions are: (1) a plaintiff-oriented exception, based on contra non valentem, that applies when failure to prosecute is caused by circumstances beyond the plaintiffs control; and (2) a defense-oriented exception, based on acknowledgment, that applies when the defendant waives his right to assert abandonment by taking actions inconsistent with an intent to treat the case as abandoned.
Clark, 785 So.2d at 784-85 (footnote omitted).
While thoroughly discussing Clark, and reiterating the three criteria for abandonment under Article 561 and the above two exceptions to the formal action requirement, the Oilfield court stated as follows:
Thus, the formal action requirement was designed to protect defendants, as “allowing informal, ex parte actions to serve as a step in the prosecution ‘might interrupt prescription against abandonment without the opposing parties formally learning of them for months or years, to their possible prejudice.’ ” Id. (quoting DeClouet [v. Kansas City Southern Ry. Co.], 176 So.2d [471,] 476 [ (La.App. 3 Cir.1965) ]). The Court concluded the absence of defendant’s un*1183conditional tender from the record did not prevent it from constituting waiver, because “[t]he purpose underlying the rule is not present when, as here, it is the defendant taking action and doing |8so in defense of plaintiffs suit to avoid penalties and attorney’s fees.” Id.
We find the reasoning in Clark is equally applicable to the present case. The April 24th letter was sent by defendant OHH and served on the remaining defendants. Further, like the insurer in Clark, OHH sent the letter in defense of the suit, i.e., to obtain discovery responses from DOTD. We conclude the purpose underlying the formal action requirement would not be served in the present case, as all defendants were aware of the letter, and thus, there is no issue of notice.
In reaching its decision in Clark, this Court also criticized our decision in Melancon v. Continental Casualty Co., 307 So.2d 308 (La.1975), which held an agreement by defendant not to take action in state court during the pendency of a federal proceeding was not a waiver, because the agreement was not filed in the state trial court. Id. at 312. Specifically, we found the “broad remark” in Melancon, stating “extrinsic proof of ... waiver cannot be permitted,” was “mistaken to the extent it precludes establishing an acknowledgment by the defendant of an obligation to plaintiff,” as it was “inconsistent with the jurisprudence holding that an order of dismissal based on abandonment may be set aside based upon ‘a showing that a cause outside the record prevented accrual of the [three] years required for abandonment’.... ” Clark, 00-3010, p. 14-15; 785 So.2d at 788-89 (quoting DeClouet, 176 So.2d at 476). Similarly, today, we hold the broad language in Melancon, requiring “any action taken by a party that is alleged to be a step in the prosecution or defense of the suit must appear in the court record” is mistaken to the extent it precludes actions made by defendants and known to all parties from constituting a step in the prosecution or defense of an action sufficient to interrupt abandonment.
Oilfield, 79 So.3d at 985 (emphasis added).
Thus, contrary to Hercules’ assertions, Oilfield did not change the law in 2011, or the Clark analysis in 2001 of the three criteria for abandonment under Article 561, or the Clark conclusion that a defendant’s waiver could be shown with extrinsic evidence of the defendant’s action that is inconsistent with an intent to | ¡¡abandon the case. Hercules has not shown any such action by the defendant. It is undisputed that waiver is not at issue in this case. Rather, Hercules raises the other exception, contra non valentem.
Contra Non Valentem Exception to Abandonment
The plaintiff-oriented exception based on contra non valentem applies when the plaintiff makes a showing that his failure to prosecute was caused by circumstances beyond his control. Clark, 785 So.2d 779. Such circumstances contemplate events which create a legal impediment, such as a plaintiffs active service in the military or confinement to a mental institution, which makes it impossible for the plaintiff to take the necessary steps to prevent abandonment. Id. The exception may apply to the automatic stay attendant with bankruptcy petitions. See Wolf Plumbing, Inc. v. Matthews, 47,822 (La.App. 2 Cir. 9/25/13), 124 So.3d 494, writs denied, 13-2510, 13-2516 (La.1/17/14), 130 So.3d 949, 950. However, when the plaintiff obtains such a stay and leaves it in place, that is not deemed a circumstance beyond his control. Faust v. Greater Lakeside Corp., 03-808 (La.App. 4 *1184Cir. 11/26/03), 861 So.2d 716, writ denied, 04-424 (La.4/2/04), 869 So.2d 887. Courts have found that circumstances beyond the plaintiff’s control include natural disasters but do not include a pro se litigant’s lack of knowledge of applicable deadlines. See Food Perfect, Inc. v. United Fire & Cas. Co., 12-2492 (La.1/18/13), 106 So.Sd 107.
Recently, in Roy v. Belt, 13-1116 (La.App. 3 Cir. 10/8/14), 149 So.3d 957, this court found no error in the trial court’s determination that the death of a judge and the subsequent issue concerning which judge had the authority to hear the case did not create a circumstance beyond the plaintiffs’ control. In Johnson v. 110Calcasieu Parish Sheriff's Dep’t, 06-1179 (La.App. 3 Cir. 2/7/07), 951 So.2d 496, this court found that the plaintiffs’ suits to recover a reward were not abandoned where the reward was dependent upon a conviction, and the conviction was obtained, then overturned, and a re-trial was in the sole discretion of the District Attorney.
■ Here, Hercules has attached in an exhibit the Lafayette Parish Sales and Use Tax Ordinance and has enumerated some of its procedural requirements in an effort to show that the Department controlled the litigation. It further contends that it had no control over when and if the taxpayer’s vendors would cooperate in providing documentation; or thousands of invoices in the hands of third parties; or delays caused by the parish auditors because of multiple ongoing audits. Hercules cites Hyman v. Hibernia Bank & Trust Co., 139 La. 411, 71 So. 598 (La.1916), and asserts that another exception exists when the inability of the plaintiff to act is brought about by the practices of the defendant. The Hyman case is highly distinguishable and inapposite because it involved fraud, concealment, and conspiracy to prevent the filing of suit; thus, Hyman involved different issues, facts, and legal analyses.
Factors that Hercules asserts as beyond its control include the Department’s timing of its 2004 assessment (for taxes owed through 2001) and the Department’s requirement that the assessed taxes be paid within several weeks. Hercules did not file its suit for refund until December, 2007. In terms of policy and the documentation difficulties that Hercules relies upon to show circumstances beyond its control, it seems that document gathering should have started shortly after the assessment in 2004 and should have yielded some results sufficient to claim that a refund was owed when suit was filed in 2007. The Department did not |n seek dismissal of the suit for refund until 2013, nine years after the assessment and twelve years after the tax period ended. This was a lingering matter.
“Abandonment is a device that the Legislature adopted ‘to put an end to the then prevailing practice of filing suit to interrupt prescription, and then letting the suit hang perpetually over the head of the defendant unless he himself should force the issue.’ ” Clark, 785 So.2d at 786 (citing Sanders v. Luke, 92 So.2d 156 (La.App. 1 Cir.1957)). While we understand the complexities involved in collecting documentation from predecessors whose employees and vendors have scattered, the courts have remedies for such problems. We find that these general, business-type delays are not the legal impediments or circumstances described in the jurisprudence that make it impossible for the plaintiff to take steps to hasten his own matter to trial.
