REED O’CONNOR, District Judge.

After reviewing all relevant matters of record in this case, including the Findings, Conclusions, and Recommendation of the United States Magistrate Judge and any objections thereto, in accordance with 28 U.S.C. § 636(b)(1), the undersigned District Judge is of the opinion that the Findings and Conclusions of the Magistrate Judge are correct and they are accepted as the Findings and Conclusions of the Court.

FINDINGS, CONCLUSIONS, AND RECOMMENDATION OF THE UNITED STATES MAGISTRATE JUDGE

IRMA CARRILLO RAMIREZ, United States Magistrate Judge.

Pursuant to Special Order No. 3-251, this case was referred for pretrial management, including the determination of nondispositive motions, and issuance of findings of fact and recommendation on dis- *559 positive motions. Before the Court are Motion of Chester Shane McVay to Vacate Final Arbitration Award and Brief in Support (doc. 1) (“P. Mot.”), filed June 20, 2007, and HES’ Opposition to McVay’s Motion to Vacate Arbitration Award and Cross-Motion to Confirm the Award and Brief (doc. 5) (“D. Mot.”), filed July 10, 2007. Based on the relevant filings, evidence, and applicable law, the Court recommends that Plaintiffs motion to vacate the final arbitration award be DENIED, Defendant’s cross-motion to confirm the award and its request for prejudgment and post-judgment interest be GRANTED, and Defendant’s request for attorney’s fees be DENIED.

I. BACKGROUND 1

This case arises from an intellectual property (“IP”) agreement between Plaintiff, Chester Shane Mcvay, and his onetime employer, Halliburton Energy Services, Inc. (“HES”). In early 2001, Plaintiff executed an IP agreement with HES and began working there as an employee. A few years later, Plaintiff accepted a job offer from another employer and announced his resignation to HES. During his exit interview, HES asked Plaintiff to return all documents, electronic or otherwise, belonging to HES. Plaintiff responded by claiming intellectual property ownership of a software program that he had worked on while an HES employee. HES subsequently filed a lawsuit and obtained a temporary restraining order against Plaintiff to compel production of the disputed documents. As a result of the restraining order, Plaintiff produced some documents and electronic files but retained possession of others. After substantial legal wrangling, HES initiated arbitration against Plaintiff for breach of their IP agreement. On March 21, 2007, the arbitrator found that Plaintiff had breached the agreement and awarded HES injunctive relief, breach of contract damages, reasonable and necessary attorneys fees, and expert witness costs. Plaintiff now moves the Court to vacate the arbitration award, and HES cross-moves to confirm the award.

II. PLAINTIFF’S MOTION TO VACATE ARBITRATION AWARD

Plaintiff moves for vacatur of the arbitration award on three grounds. He first moves to vacate the final award arguing that the arbitrator was partial in making the award. (P. Mot. at 3-5). Alternatively, he moves to vacate portions of the award, claiming that the arbitrator exceeded her powers and acted in manifest disregard of the law. (P. Mot. at 5-9).

A. Legal Standard

Pursuant to the Federal Arbitration Act (“FAA”), if the parties have agreed that a judgment of the court shall be entered upon the entry of an arbitration award, then upon application by a party, the court must grant such an order unless the award is vacated, modified, or corrected. 9 U.S.C. § 9. The FAA authorizes a district court to vacate an arbitration award where: (1) the award was procured by corruption, fraud, or undue means; (2) there is evidence of partiality or corruption among the arbitrators; (3) the arbitrators were guilty of misconduct which prejudiced the rights of one of the parties; or (4) the arbitrators exceeded their powers. 9 U.S.C. § 10(a). The Court may vacate an arbitration award under the FAA only for these statutory reasons. Hall Street Assocs., L.L.C. v. Mattel, Inc., 552 U.S. 576, 128 S.Ct. 1396, 1403, 170 L.Ed.2d 254 (2008) (holding that § 10 provides the exclusive grounds for expedited vacatur); Citigroup Global Mkts. Inc. v. Bacon, 562 *560 F.3d 349, 358 (5th Cir.2009) (overruling previous non-statutory grounds for supporting vacatur of an arbitration award). The court is to give deference to the arbitrator’s decision and review of an arbitration award is “extraordinarily narrow.” Glover v. IBP, Inc., 334 F.3d 471, 473-74 (5th Cir.2003).

B. Partiality

Plaintiff first moves the Court to vacate the final award claiming that the arbitrator was partial in making the award. (P. Mot. at 3-5).

Section 10(a)(2) of the FAA authorizes a district court to vacate an arbitration award if there is “evident partiality 2 or corruption in the arbitrators.” 9 U.S.C. § 10(a)(2). The party asserting evident partiality has the burden of proof. Mantle v. Upper Deck Co., 956 F.Supp. 719, 729 (N.D.Tex.1997) (Fitzwater, J.). The party carrying this “onerous burden” must produce specific facts. Id. Additionally, “the alleged partiality must be direct, definite and capable of demonstration rather than remote, uncertain, or speculative.” Id. (citations and internal quotations omitted). A party “can establish evident partiality by demonstrating that the arbitrator failed to disclose relevant facts or that he displayed actual bias at the arbitration proceeding.” Weber v. Merrill Lynch Pierce Fenner & Smith, 455 F.Supp.2d 545, 549 (N.D.Tex.2006) (Fitzwater, J.) (citations omitted). Id. Plaintiff seeks to establish evident partiality by showing nondisclosure and actual bias.

1. Non-Disclosure

To evaluate evident partiality in non-disclosure cases, the Fifth Circuit has adopted a “reasonable impression of bias” standard. Positive Software Solutions Inc. v. New Century Mortg. Corp., 476 F.3d 278, 283 (5th Cir.2007). Under this standard, a party seeking to vacate an arbitration award must demonstrate something more than a mere appearance of bias emanating from the arbitrator’s failure to disclose a contact or relationship; it must show a reasonable impression of bias created by the arbitrator’s non-disclosure. See id. at 282-84, see also Bernstein Seawell & Kove v. Bosarge, 813 F.2d 726, 732 (5th Cir.1987). To rise to the level of evident partiality, “[a]n arbitrator’s failure to disclose must involve a significant compromising connection to the parties,” not something “trivial and insubstantial.” Positive, 476 F.3d at 282-83.

Plaintiff argues that the arbitrator demonstrated evident partiality by waiting until after the arbitration hearing to disclose a social relationship. (P. Mot. at 3-4). Plaintiff alleges that the arbitrator and her husband were neighbors with, and had a social relationship with, the son of a named party to the proceeding. He claims that the arbitrator’s husband corresponded with the neighbor and even picked up his mail. He further claims that the arbitrator revealed this social relationship after the arbitration hearing even though the relationship was discoverable a month before the hearing. This suspiciously-timed revelation, he alleges, created a reasonable impression of bias.

Even though the arbitrator disclosed the social relationship two months before she issued the final arbitration award, Plaintiff waited until after the arbitration award to claim partiality based on *561 non-disclosure. Plaintiff waived any objection based on non-disclosure when he failed to object to the continued service of the arbitrator after she disclosed the relationship. See Ergobilt, Inc. v. Neutral Posture Ergonomics, Inc., 2002 WL 1489521, at *5 (N.D.Tex.2002) (Lindsay, J.). A party cannot stand by during arbitration, withhold certain arguments, and upon losing, raise those arguments in federal court. Gateway Techs. Inc. v. MCI Telecomms. Corp., 64 F.3d 993, 998 (5th Cir.1995). Since Plaintiff has waived any objections based on non-disclosure, the Court should not vacate the award on these grounds.

2. Actual Bias

Plaintiff moves to vacate the final award on grounds that the arbitrator displayed actual bias and evident partiality in issuing the award. (P. Mot. at 4-5; doc. 19).

The court uses an objective standard to determine whether the arbitrator displayed actual bias at the arbitration proceeding. Weber, 455 F.Supp.2d at 550 (citing Mantle, 956 F.Supp. at 729). Under this standard, a mere appearance of bias by the arbitrator is not enough. Id. Rather, the party asserting actual bias must produce specific facts to show that “a reasonable person would have to conclude that the arbitrator was partial to one party.” Id. (citations and internal quotations omitted).

Here, Plaintiff claims that the arbitrator displayed actual bias by improperly reviewing HES’ proposed award while not giving him an opportunity to present his own for consideration. He concedes that the arbitrator refused to consider the proposed award when HES submitted it for consideration, but relies on similarities in language in the proposed and final awards to conclude that the arbitrator improperly reviewed the proposed award. Plaintiff does not account for the fact that the final award’s language is much more similar to language in a reply brief that HES properly submitted to the arbitrator for consideration. Given these facts, a reasonable person would not have to conclude that the arbitrator improperly reviewed and relied on HES’ proposed award thus displaying actual bias towards Plaintiff.

Plaintiff also claims actual bias by alleging that the arbitration was “marred with irregularities from files used as evidence having been resaved and modified, personal files going missing from computers after searches, and disregard for the clear terms of a questionably-obtained temporary restraining order.” (P. Mot. at 5). However, he does not provide specific facts to show that the irregularities, if any, were linked to the arbitrator. Plaintiff’s allegations of actual bias are at most remote, uncertain, and speculative rather than direct, definite, and capable of demonstration. See Mantle, 956 F.Supp. at 729. Since Plaintiff has failed to meet his burden to show actual bias, the Court should deny vacatur of the arbitration award on these grounds.

C. Exceeding Powers

Plaintiff moves to vacate portions of the arbitration award on the grounds that the arbitrator exceeded her powers. (P. Mot. at 5).

An arbitration award may be vacated where an arbitrator exceeds his powers. Brook v. Peak Int'l, Ltd., 294 F.3d 668, 672 (5th Cir.2002). To determine whether an arbitrator exceeded his powers, a court must examine the language in the arbitration agreement. Glover, 334 F.3d at 474. When an arbitration agreement gives an arbitrator authority to interpret and apply a contract, the arbitrator’s construction of that contract must be enforced as long as the arbitrator’s decision “draws its essence” from the underly *562 ing contract. Id.; Executone Info. Sys., Inc. v. Davis, 26 F.3d 1314, 1320 (5th Cir.1994). In other words, a court “must affirm the arbitrator’s decision if the decision is rationally inferable from the letter or purpose of the underlying agreement.” Executone, 26 F.3d at 1320. In deciding whether the arbitrator exceeded his authority, a court must resolve all doubts in favor of the arbitrator’s decision. Id. at 1320-21.

Plaintiff moves to vacate the breach of contract damages award on the ground that the arbitrator improperly included expert fees in the award in contravention of HES’ dispute resolution rule (“DRR”) 32.D which provides that “the fees and expenses of experts ... retained or consulted by a Party shall be borne by the party utilizing those services.” (P.App. at Oil). While the arbitrator did include expert fees in her award of breach of contract damages, she characterized them as reasonable and necessary mitigation expenses recoverable under the law 3 in a breach of contract action. (P.App. at 025). The arbitrator’s authority to grant expert fees as mitigation damages is rationally inferable from DRR 30, DRR 33, and § 8 of HES’ dispute resolution plan. (See P.App. at 005-006, 010-011). DRR 30 requires the arbitrator to be bound by applicable law while § 8 of HES’ dispute resolution plan grants her very broad authority to determine applicable law as well as grant any relief, legal or equitable, that a court would grant based on a particular claim. 4 Id. Most significantly, DRR 33 requires the arbitrator to interpret the rules “insofar as they relate to [her] powers and duties.” (P.App. at 011). It is also noteworthy that DRR 32.D does not prohibit the award of expert fees as mitigation damages even if it requires that the parties bear their own expert fees and expenses. (P.App. at Oil). “If an arbitrator is even arguably construing or applying the contract and acting within the scope of his authority, the fact that a court is convinced he committed serious errors does not suffice to overturn his decision.” Major League Baseball Players Ass’n v. Garvey, 532 U.S. 504, 509, 121 S.Ct. 1724, 149 L.Ed.2d 740 (2001). Since the arbitrator’s award of expert fees as mitigation damages derives its essence from the underlying arbitration agreement, the Court should not vacate this award.

Plaintiff next moves the Court to strike down the award of expert witness costs to HES. He alleges that the arbitrator awarded expert witness costs to HES in violation of DRR 32.D which requires parties utilizing the services of experts “retained on consulted” to bear their fees and expenses. (P.App. at Oil). Plaintiff, however, does not take into account DRR 32.A which allows the arbitrator to award “witness” expenses. 5 Id. Based on the language of DRR 32.A and DRR 32.D, it can be inferred that the arbitrator could award expert witness costs, even if she could not award costs for experts consulted or retained for other purposes. Since the arbi *563 trator’s award of expert witness costs is rationally inferable from the underlying arbitration agreement, the Court should not vacate this award. Executone, 26 F.3d at 1320. 6

D. Manifest Disregard of the Law

Plaintiff moves the court to set aside the award of injunctive relief and attorney’s fees on the grounds that the arbitrator made the awards in manifest disregard of the law. (P. Mot. at 7-9).

The Fifth Circuit previously recognized manifest disregard of the law as a non-statutory or common law ground for vacating an arbitration award. See e.g. Sarofim v. Trust Co. of the West, 440 F.3d 213, 216 (5th Cir.2006). Recently, however, it overruled its own precedent in Citigroup Global and held that manifest disregard of the law is no longer an independent, non-statutory basis for vacating an arbitration award under the FAA. 562 F.3d at 355, 358. Under Citigroup Global, a court may vacate an arbitration award only for reasons provided in § 10 of the FAA. Id. at 358 (citing Hall Street, 128 S.Ct. at 1405).

In this case, Plaintiff raises manifest disregard of the law as a non-statutory basis for vacating the arbitrator’s award of injunctive relief and attorney’s fees. Under the specific holding of Citigroup Global, the Court is foreclosed from reviewing this non-statutory ground. See Saipem Am. v. Wellington Underwriting Agencies, Ltd., 335 Fed.Appx. 377, 379-80 (5th Cir.2009). 7

III. DEFENDANT’S CROSS-MOTION TO CONFIRM THE AWARD

HES moves the Court to confirm the award, and to grant prejudgment interest, post-judgment interest, and attorneys fees and costs for the current litigation. (D. Mot. at 14-15).

Pursuant to the FAA, a court may enter judgment on the arbitration award if the parties have agreed that the court may do so, and the award has not been vacated, modified, or corrected. See 9 U.S.C. § 9; McKee v. Home Buyers Warranty Corp. II, 45 F.3d 981, 985 (5th Cir.1995) (citing 9 U.S.C. § 9). In this case, Plaintiff and HES agree that the Court may enter judgment on the arbitration award. DRR 31.D specifically provides for this agreement when it states that the “Parties to these rules shall be deemed to have consented that judgment upon the award of the arbitrator may be entered and enforced in any federal or state court having jurisdiction of the Parties.” (P.App. at Oil). Given the parties’ consent that the Court may enter judgment on the award and the Court’s ruling that the award should not be vacated, the Court should confirm the arbitrator’s final award.

Plaintiff asserts that a full confirmation of the final award in this case is *564 unwarranted because he has already met a number of directives of the injunctive relief award. Under Fifth Circuit precedent, however, there is no requirement that a party refuse to honor the arbitration award before a court can confirm the award. Variable Annuity Life Ins. Co. v. Bencor, Inc., 2006 WL 1492249, at *4 (S.D.Tex. May 30, 2006). Confirmation is appropriate even where the parties have fully complied with the award. See id. at *3-4 (confirming award even though the party opposing confirmation did not seek modification or vacatur, and had paid the award in full). Plaintiffs assertion therefore is without merit and the Court should fully confirm the award.

A. Prejudgment Interest

HES seeks prejudgment interest from the date the arbitrator made the award through the entry of the final judgment. Id. Texas law governs whether a court should grant prejudgment interest on an arbitration award. See Executone, 26 F.3d at 1329 (applying state law in reviewing a district’s court’s denial of prejudgment interest); Northrop Corp. v. Triad Int’l Mktg., S.A, 842 F.2d 1154, 1155 (9th Cir.1988) (applying state law to the “determination of pre-judgment interest in a diversity suit” under the FAA). Under Texas law, a trial court must grant a prevailing party prejudgment interest on the arbitration award in all but exceptional circumstances. See Executone, 26 F.3d at 1330; Richter, S.A. v. Bank of Am. Nat’l Trust & Sav. Ass’n, 939 F.2d 1176, 1197 (5th Cir.1991) (citing Cavnar v. Quality Control Parking, 696 S.W.2d 549 (Tex.1985); Matthews v. DeSoto, 721 S.W.2d 286, 287 (Tex.1986); Concorde Limousines Inc. v. Moloney Coachbuilders, Inc., 835 F.2d 541, 549 (5th Cir.1987)). The award “bears interest in the same manner as a judgment of a court of last resort in Texas.” Executone, 26 F.3d at 1330 (citing Kermacy v. First Unitarian Church, 361 S.W.2d 734, 735-36 (Tex.Civ.App.-Austin 1962, writ ref'd n.r.e)). Where, as here, the arbitration agreement does not address interest, “interest at the rate of six percent per year is allowed ... beginning on the 30th day after the date on which the amount is due and payable.” Kvaerner Oilfield, Inc. v. Cooper Cameron Corp., 2007 WL 1850014, at *8 (S.D.Tex. June 26, 2007) (citing Tex. Fin.Code § 302.002). Since Plaintiff does not allege any exceptional circumstances warranting its denial, HES is entitled to prejudgment interest at the rate of six percent per year from April 20, 2007 8 to the date of the judgment.

B. Post-Judgment Interest

HES also requests the Court to grant post-judgment interest. (D. mot. at 15). Federal law governs a reward of post-judgment interest. Cycle Sport, L.L.C. v. Dinli Metal Indus. Co., Ltd., 2008 WL 4791544, at *6 (N.D.Tex. Oct. 30, 2008) (citing Hall v. White, Getgey, Meyer Co., LPA 465 F.3d 587, 594-95 (5th Cir.2006)). 28 U.S.C. § 1961(a) specifically provides that post-judgment interest “shall be allowed on any money judgment in a civil case recovered in a district court.” The statute further provides that the “interest shall be calculated from the date of the entry of the judgment, at a rate equal to the weekly average 1-year constant maturity Treasury yield, as published by the Board of Governors of the Federal Reserve System, for the calendar week preceding the date of judgment.” 28 U.S.C. § 1961(a). Because a district court’s confirmation of an arbitration *565 award is equivalent, in every respect, to any other judgment entered by the court, it is also subject to post-judgment statutory interest under § 1961. Kvaerner, 2007 WL 1850014, at *9 (citations omitted). HES is entitled to post-judgment interest on the arbitration award at the rate provided in § 1961 from the date of the judgment until the date the award is paid. See id.

C. Attorney Fees and Costs

HES also seeks attorney’s fees incurred in defending against Plaintiffs motion to vacate. (D. Mot. at 15). A district court may award attorney’s fees against a party if its challenges to an arbitration award “are not cognizable under the FAA, are frivolous, or are without legal justification.” Ergobilt, 2002 WL 1489521, at *10 (citing Int’l Ass’n of Machinists & Aerospace Workers, Dist. 776 v. Tex. Steel Co., 639 F.2d 279, 283 (5th Cir.1981)). The FAA and the Fifth Circuit both recognize Plaintiffs challenges to the arbitration award. Because the challenges are not frivolous, the Court should deny HES’ request for attorney’s fees.

IV. CONCLUSION

Plaintiffs motion to vacate the arbitration award should be DENIED. Defendant’s motion to confirm the award and its request for prejudgment and post-judgment interest should be GRANTED, and its request for attorney’s fees should be DENIED.

SO RECOMMENDED, on this 13th day of November, 2009.

. The background facts are derived from the parties’ pleadings and are not contested.

. Plaintiff first argued that the parties had contracted for a “mere appearance of bias standard” for evaluating the arbitrator’s partiality, and that § 10(a)(2)’s evident partiality standard did not apply. (P. Mot. at 4). He now concedes that under the recent Supreme Court decision in Hall Street, § 10 provides the exclusive regime for judicial review of an arbitration award under the FAA. (See doc. 19).

. In granting expert fees as part of the breach of contract damages award, the arbitrator explained that she relied on case law that HES submitted to her and that allowed a plaintiff in a breach of contract action to recover reasonable and necessary mitigation expenses. (P.App. at 025).

. Specifically, § 8 provides: "In the case of arbitration, the arbitrator shall have the authority to determine the applicable law and to order any and all relief, legal or equitable, including punitive damages which a party could obtain from a court of competent jurisdiction on the basis of the claims made in the proceeding.” (P.App at 005-006).

. DRR 32.A states that "the expenses of witnesses shall be borne by the party producing such witnesses, except as otherwise provided by law or in the award of the arbitrator.” (P.App. at Oil)

. HES contends that Plaintiff waived his "exceeds powers” argument by not raising it to the arbitrator based on Rule 32.D. Even though Plaintiff did not object to the arbitrator's authority based on Rule 32.D, he did object to the award of expert fees under Texas law. (D.App. at 034-036); See NetKnowledge Techs., LLC. v. Rapid Transmit Techs., No. 3:02-CV2406-M, 2007 WL 518548, at *3 (N.D.Tex. Feb. 20, 2007) (since the party maintained throughout arbitration that certain claims were barred by the applicable agreement, his failure to formally object to the arbitrator’s authority did not waive that objection). No waiver occurred.

. In Saipem, the Fifth Circuit was presented with the issue of whether the Supreme Court's decision in Hall Street forecloses a court's review of the arbitration award on non-statutory grounds. Relying on Citigroup Global, the Fifth Circuit held that a court may vacate an arbitration award only if a statutory ground supports the vacatur. It then proceeded to consider the statutory grounds for vacatur presented in that case.

. This date is 30 days from March 23, 2007, when the arbitrator entered the final award against Plaintiff.
