                                       _________________

       RONALD LEE GILMAN, Circuit Judge. Bruce Stevens worked for Baker Petrolite
Corporation and its predecessor for approximately seven years. When his employment ended,
Stevens signed a contract in which he promised to maintain the confidentiality of Baker
Petrolite’s trade secrets. Baker Petrolite and its parent company, Baker Hughes Incorporated
(collectively, Baker), sued Stevens 18 years after the contract was signed, alleging a breach of
their confidentiality agreement. Stevens’s defense, and the outcome of this case, hinges on the
validity of a broadly worded settlement agreement that was purportedly reached in the interim as
a result of an unrelated lawsuit between the parties. Relying on this settlement agreement, the
district court entered judgment in favor of Stevens.        For the reasons set forth below, we
AFFIRM the judgment of the district court.

                                       I. BACKGROUND

A.     The parties and the disputed settlement agreement

       Baker produces and sells chemicals such as polyethylenes, alcohols, and copolymers.
These operations involve proprietary “ethylene polymerization processes” (the EP Processes),
which allegedly constitute trade secrets under state law.

       Stevens worked for Baker and its predecessor from 1989 until 1996. His employment
involved extensive use of the EP Processes. When Stevens’s employment ended, he signed a
Termination Agreement in which he promised not to disclose any information or data related to
Baker’s business or technology, including trade secrets such as the EP Processes.

       In October 1999, Stevens sued Baker in Oklahoma state court. Stevens alleged that
Baker had failed to fully pay the compensation due him during his employment. The parties
eventually settled Stevens’s lawsuit. In consummation of the settlement, Baker paid Stevens
$10,000, and Stevens dismissed his lawsuit against Baker with prejudice.
No. 15-2413               Baker Hughes, et al. v S&S Chemical, et al.                 Page 3

       The parties dispute the remaining terms of the settlement. In particular, the negotiations
preceding the cash payment to Stevens involved the circulation of several drafts of a proposed
settlement agreement that included a release of all claims.          A purported final draft (the
Settlement) was sent from Baker to Stevens’s attorney, Robert Giles, on March 30, 2000.
Stevens and Giles signed the Settlement the following day. Giles then faxed a copy of the signed
Settlement to Baker’s attorney, Steven Broussard, on April 7, 2000. That same day, Broussard
forwarded a copy of the Settlement to Baker’s in-house counsel, Jeff Shank. The Settlement
contained signature blocks for both Broussard and for a representative of Baker, but the record
has no copy of the Settlement showing that either Broussard or a Baker official ever signed the
document. Instead, the record contains only the copy of the Settlement signed by Stevens and
Giles on March 31, 2000 and faxed to Baker on April 7, 2000.

       The terms of the Settlement are consistent with the above-described resolution of
Stevens’s Oklahoma lawsuit insofar as the Settlement required Stevens to dismiss his complaint
in exchange for $10,000. The Settlement, however, has additional terms. As relevant to the
current appeal, the Settlement contains a general release (the Release Provision) that provides as
follows:

       Except for the obligations set forth in this Agreement, Baker hereby fully and
       forever remises, releases and discharges Stevens and his attorneys, agents, heirs,
       executors, administrators, predecessors, successors and assigns (collectively
       referred to as the “Stevens Release Parties”), of and from any and all claims,
       demands, agreements, contracts, covenants, suits, actions, causes of action,
       obligations, controversies, debts, costs, expenses, damages, judgments, losses and
       liabilities, of whatever kind or nature, in law, equity or otherwise, whether known
       or unknown, concealed or hidden, against any of the Stevens Released Parties
       which Baker has had, may have had or now has, to and including the date of this
       Agreement.

       It is the intention of the parties to this Agreement that the foregoing general
       releases shall be effective as a bar to all actions, causes of action, suits, claims or
       demands of every kind, nature or character whatsoever, known or unknown,
       suspected or unsuspected, fixed or contingent, referred to above. . . .
No. 15-2413               Baker Hughes, et al. v S&S Chemical, et al.            Page 4

B.     Stevens’s subsequent activities

       In or around 1999, Stevens formed S&S Chemical, LLC (S&S) as a Colorado limited
liability company for the purpose of producing polyethylene products. Baker subsequently came
to suspect that S&S was improperly using Baker’s EP Processes in doing so. This caused Baker
to send Stevens a letter in 2002 reminding Stevens that he had previously promised (in the
Termination Agreement) that he would not disclose information relating to the EP Processes or
to Baker’s other trade secrets. Stevens responded that he and his company had independently
developed the processes used to manufacture S&S’s chemicals, and Baker later confirmed that
S&S was not then using Baker’s confidential information.

       Several years later, Baker again came to suspect that Stevens and S&S were using
Baker’s EP Processes. This suspicion arose from a 2013 press release in which S&S announced
that it was producing a new line of polymer chemicals. Baker’s investigation concluded that
S&S’s production likely involved the use of Baker’s trade secrets. In addition, Baker learned
during its investigation that Stevens and S&S had sold certain intellectual property to SPE Wax
Technologies, LLC (SPE). Baker determined that this sale likely involved the disclosure of the
EP Processes or other information that Stevens had previously promised not to divulge.

C.     Baker’s lawsuit

       Based on its investigation, Baker sued Stevens, S&S, and SPE (collectively, Defendants)
in May 2014 in the United States District Court for the Western District of Michigan. Baker
alleged in relevant part that (1) Stevens had breached the Termination Agreement by disclosing
Baker’s trade secrets to SPE, and (2) Defendants had misappropriated Baker’s trade secrets by
using the EP Processes.

       Baker filed an amended complaint in June 2014, and the district court entered a
case-management order in December of that year. The court’s order required the parties to make
their initial disclosures as mandated by Rule 26(a) of the Federal Rules of Civil Procedure by
January 14, 2015. In addition, the court later imposed a deadline of July 30, 2015 for the
completion of lay-witness discovery.
No. 15-2413                Baker Hughes, et al. v S&S Chemical, et al.              Page 5

       Defendants timely made their initial disclosures. The disclosures listed 79 individuals
likely to have discoverable information, but the list did not include Robert Giles, the attorney
who had represented Stevens in the Oklahoma state-court litigation. Giles’s name did not
surface until Baker located and produced a copy of the Settlement during subsequent discovery.

       In April 2015, Baker filed a second amended complaint, again alleging breach of contract
and the misappropriation of trade secrets. Defendants answered the amended complaint the
following month. In doing so, they asserted as an affirmative defense that Baker’s claims were
barred by the Release Provision. As support, Defendants cited the Settlement that the parties had
allegedly entered into in connection with the resolution of Stevens’s 1999 Oklahoma lawsuit
against Baker. They noted that the Settlement’s Release Provision applied to all “demands,
agreements, contracts, . . . [and] obligations . . . of whatever kind or nature.”    As a result,
Defendants asserted that Baker had released Stevens from the confidentiality obligations of the
Termination Agreement, thereby undercutting Baker’s misappropriation and breach-of-contract
claims. Defendants attached as Exhibit A to their answer a copy of the Settlement that Stevens
and Giles had signed on March 31, 2000. At no point, however, did Defendants supplement their
disclosures under Rule 26(a) to identify Giles as a person having information that would be used
to support their claims or defenses.

       In August 2015, Defendants filed a motion for summary judgment on the basis that
Baker’s claims were barred by the Release Provision. Included with the motion were (1) a
declaration from Giles regarding his role in the resolution of the Oklahoma lawsuit, and (2) a
copy of Giles’s billing records from his work on that lawsuit.

       Baker responded to the motion by, among other things, moving to strike Giles’s
declaration and billing records on the grounds that Giles had not been identified in Defendants’
Rule 26(a) disclosures and that Giles’s billing records had not been produced during discovery.
It also asserted that (1) Giles’s declaration was improper under Rule 56(c)(4) of the Federal
Rules of Civil Procedure because it contained speculation and legal conclusions, and (2) the
billing records were inadmissible because they had not been authenticated and/or because they
contained hearsay.
No. 15-2413               Baker Hughes, et al. v S&S Chemical, et al.              Page 6

       The district court granted Defendants’ motion for summary judgment in October 2015.
It first addressed and rejected Baker’s motion to strike Giles’s declaration and billing records.
The court then cited Giles’s declaration and records in concluding that the parties had assented to
the terms of the Settlement and that the Settlement constituted a valid contract under Oklahoma
state law.

       It next proceeded to interpret the terms of the Settlement. The district court determined
that the Release Provision unambiguously released Stevens from the obligations of the
Termination Agreement. As a result, the court concluded that Stevens was not liable for breach
of contract. In addition, the court decided that, without an underlying breach of contract, there
had been no “improper” use or disclosure of Baker’s trade secrets. The court thus concluded that
Defendants were not liable for the alleged misappropriation of Baker’s EP Processes.

       Baker now appeals. It first asserts that the district court erred in concluding that the
Settlement is a valid contract, primarily because the record does not contain a copy of the
Settlement that is signed by Baker. Baker next argues that the court should have struck Giles’s
declaration and records. It maintains that Giles and his records were not disclosed during
discovery, with the consequence that they should have been excluded from the court’s
consideration under Rule 37 of the Federal Rules of Civil Procedure. Baker also asserts that
Giles’s declaration violated Rule 56(c)(4) of the Federal Rules of Civil Procedure because it was
not based on personal knowledge. Finally, Baker contends that the court erred in interpreting the
Settlement by failing to consider the parties’ conduct post-dating the resolution of Stevens’s
Oklahoma lawsuit.

                                         II. ANALYSIS

A.     Standards of review

       Baker first challenges the district court’s grant of summary judgment in favor of Stevens.
We review de novo the court’s decision to grant summary judgment. See Watson v. Cartee,
817 F.3d 299, 302 (6th Cir. 2016). Summary judgment is appropriate when, construing the facts
and drawing all reasonable inferences in favor of the nonmoving party, there is no genuine
dispute regarding any material fact and the moving party is entitled to judgment as a matter of
No. 15-2413                 Baker Hughes, et al. v S&S Chemical, et al.              Page 7

law. Rocheleau v. Elder Living Constr., LLC, 814 F.3d 398, 400 (6th Cir. 2016); Fed. R. Civ. P.
56(a).

         Baker next challenges the district court’s refusal to strike Giles’s declaration and billing
records in accordance with Rules 37(c)(1) and 56(c)(4) of the Federal Rules of Civil Procedure.
We review such rulings “under the highly deferential abuse-of-discretion standard.” See Ondo v.
City of Cleveland, 795 F.3d 597, 603 (6th Cir. 2015) (internal quotation marks omitted); see also
Briggs v. Potter, 463 F.3d 507, 511 (6th Cir. 2006) (applying the standard to a dispute under
Rule 56(c)(4)’s predecessor). An abuse of discretion occurs if the district court “relies on
erroneous findings of fact, applies the wrong legal standard, misapplies the correct legal standard
when reaching a conclusion, or makes a clear error of judgment.” Ondo, 795 F.3d at 603
(internal quotation marks omitted).

         Baker finally challenges the district court’s interpretation of the Settlement. We review
contractual interpretations de novo. Meridian Leasing, Inc. v. Associated Aviation Underwriters,
Inc., 409 F.3d 342, 346 (6th Cir. 2005).

B.       The district court correctly concluded that the Settlement is a binding contract

         The district court granted summary judgment in favor of Defendants on Baker’s breach-
of-contract and misappropriation claims on the ground that Baker had released Stevens from his
underlying confidentiality obligations. Baker concedes that the Release Provision is applicable
to Stevens’s Termination Agreement if the Settlement is indeed binding on Baker, but it argues
that a genuine factual dispute exists with regard to whether the Settlement was agreed to by
Baker. As explained below, we conclude that no such dispute exists and that the Settlement is
binding.

         1.     Choice of law and principles of contract formation

         The district court had jurisdiction based upon the parties’ diversity of citizenship, so we
apply the choice-of-law rules of the state in which the district court sits—in this case, Michigan.
See Performance Contracting Inc. v. DynaSteel Corp., 750 F.3d 608, 611 (6th Cir. 2014).
Applying Michigan’s rules, the court concluded that Oklahoma law governed its evaluation of
No. 15-2413                Baker Hughes, et al. v S&S Chemical, et al.                  Page 8

the Settlement. The parties do not challenge this conclusion on appeal, so we likewise apply
Oklahoma law. See Wilton Corp. v. Ashland Castings Corp., 188 F.3d 670, 673 n.2 (6th Cir.
1999) (“We need not inquire into choice-of-law issues; the parties did not dispute that Ohio law
applied.”).

       A valid contract in Oklahoma consists of four elements: “Parties capable of contracting,”
“consent,” a “lawful object,” and “[s]ufficient cause or consideration.” Okla. Stat. tit. 15, § 2.
The parties in this case dispute only whether there was mutual consent to the terms of the
Settlement.

       Consent to contractual terms is reached through the process of offer and acceptance.
Garrison v. Bechtel Corp., 889 P.2d 273, 281 (Okla. 1995) (“Every contract results from an offer
and acceptance.”); Nat’l Outdoor Advert. Co. v. Kalkhurst, 418 P.2d 661, 664 (Okla. 1966) (“It
is an elementary rule of law in this jurisdiction that in order to constitute a contract there must be
an offer on the part of one and an acceptance on the part of the other.”).

       An “offer” is an “expression of a person’s willingness to become, according to the terms
expressed, a party to an agreement.” Strahm v. Bd. of Trs. of Benevolent & Protective Order of
Elks, Tulsa Lodge 946, 225 P.2d 159, 161 (Okla. 1950) (citation omitted). To give rise to an
enforceable contract, the offer must contain enough detail that the terms of the contract can be
“ascertained with a reasonable degree of certainty.” Brown v. Bivings, 277 P.2d 671, 673 (Okla.
1954); see also Okla. Stat. tit. 15, § 104 (providing that a contract is void if its terms are “so
vaguely expressed as to be wholly unascertainable”).

       An “acceptance” is an “expression of the intent to accept the offer, by word, sign, writing
or act, communicated or delivered to the person making the offer or the offeror’s agent.”
Garrison, 889 P.2d at 281. A party can demonstrate its acceptance by performing according to
the terms of an offer or by accepting the consideration accompanying the offer. Hardin v. First
Cash Fin. Servs., Inc., 465 F.3d 470, 476 (10th Cir. 2006) (“In general, Oklahoma follows
traditional contract principles in permitting acceptance of an offer by performance:
‘Performance of the conditions of a proposal, or the acceptance of the consideration offered with
a proposal, is an acceptance of the proposal.’” (quoting Okla. Stat. tit. 15, § 70)).
No. 15-2413                Baker Hughes, et al. v S&S Chemical, et al.             Page 9

       To constitute a valid acceptance, the response to an offer must be “unconditional” and
“identical to the offer.” Ollie v. Rainbolt, 669 P.2d 275, 280 (Okla. 1983). If the response
instead imposes conditions or “introduces a new and material term,” then the response
constitutes a counteroffer that the original offeror may accept or reject. Midwest Eng’g &
Constr. Co. v. Elec. Regulator Corp., 435 P.2d 89, 96 (Okla. 1967) (citation omitted).
Acceptance of the counteroffer results in the formation of a valid contract. Id.

       2.      The parties consented to the terms of the Settlement

       Based on the foregoing principles, we conclude that Baker and Stevens consented to the
terms of the Settlement through the process of offer and acceptance. This process began when
the parties entered negotiations in December 1999 to settle Stevens’s Oklahoma lawsuit. Several
months later, on March 30, 2000, Baker sent to Stevens’s attorney a draft of the Settlement that
was titled “Settlement Agreement and Full and Final Mutual Release of Claims.” This draft set
out the terms of the proposed settlement, including the provisions that (1) Baker would pay
Stevens $10,000, (2) Stevens would dismiss his lawsuit with prejudice, and (3) the parties would
release all claims and obligations against each other by assenting to the Release Provision. The
draft thus easily contained enough detail so that the Settlement’s terms could be “ascertained
with a reasonable degree of certainty.” See Brown, 277 P.2d at 673. In addition, Baker’s
conduct in sending the draft to Stevens indicated that Baker was willing to enter into an
agreement with Stevens based on the terms expressed therein. As a result, the transmission of
the Settlement to Stevens constituted an offer. See Strahm, 225 P.2d at 161 (defining an “offer”
as an “expression of a person’s willingness to become, according to the terms expressed, a party
to an agreement”).

       The offer was then accepted. First, Stevens and his attorney signed the draft of the
Settlement, thereby demonstrating their assent to its terms. See Garrison, 889 P.2d at 281
(noting that an “acceptance” may be accomplished “by word, sign, writing or act”). Second,
Stevens did not add or delete any terms or otherwise make any changes to the draft; instead, he
simply signed the copy of the draft that Baker had transmitted. Stevens thus unconditionally
assented to an agreement containing the exact same terms as contained in Baker’s offer.
See Ollie, 669 P.2d at 280 (observing that an acceptance must be “unconditional” and “identical
No. 15-2413               Baker Hughes, et al. v S&S Chemical, et al.              Page 10

to the offer”). Finally, Stevens communicated his acceptance to Baker when his attorney, Giles,
faxed the signed draft of the Settlement to Baker’s counsel.       This transmission completed
Stevens’s acceptance of the Settlement. See Garrison, 889 P.2d at 281 (“[An acceptance] must
be . . . communicated or delivered to the person making the offer or the offeror’s agent.”);
see also Okla. Stat. tit. 15, § 51 (“The consent of the parties to a contract must be
. . . [c]ommunicated by each to the other.”).    As a result of this offer and acceptance, we
conclude that the Settlement—including the Release Provision—is a binding contract between
Baker and Stevens.

       Baker contests this result on several grounds. It first argues that a genuine dispute of
material fact exists because the record does not contain a copy of the Settlement signed by
Baker. This omission from the record ostensibly “creates a strong inference” that Baker did not
assent to the Release Provision, leading Baker to conclude that the district court should have
allowed Baker’s claims to go to a jury.

       We find this argument unpersuasive. First, nothing in the record suggests that Baker’s
offer was expressly conditioned upon Baker later signing the Settlement. Cf. Herren v. Okla.
Nat. Gas Co., 166 P.2d 95, 96 (Okla. 1946) (noting that an offer may be conditioned upon the
happening of later events); Restatement (Second) of Contracts: To Whom an Offer is Addressed
§ 29 cmt. a (Am. Law Inst. 1981) (observing that an offeror may limit an offeree’s power of
acceptance). Second, the Oklahoma Supreme Court has specifically observed that “it is not
always necessary that a written contract be signed by the parties[] to become a binding contract.”
Stewart v. Bd. of Educ., Sch. Dist. No. 2, Stephens Cty., 230 P. 504, 505 (Okla. 1924). We are
therefore unpersuaded by Baker’s argument that the absence of a fully signed copy of the
Settlement necessarily “creates a strong inference” that no mutual consent was reached.

       Moreover, the Oklahoma Supreme Court explained in Stewart that a “contract signed by
but one of the parties thereto is binding upon both, when acts thereunder have been performed by
both parties.” Id. (citation omitted). In the present case, both parties undisputedly performed
according to the terms of the Settlement. Baker paid Stevens $10,000 and Stevens dismissed his
Oklahoma lawsuit, just as the Settlement required. So even if Stevens’s transmission of the
No. 15-2413                Baker Hughes, et al. v S&S Chemical, et al.              Page 11

Settlement to Baker did not in and of itself form a valid contract, the parties’ subsequent conduct
caused the Settlement to become binding. See id.; see also Okla. Stat. tit. 15, § 70.

       Nor are we concerned with whether the parties performed each and every obligation
imposed by the Settlement. This is because “the beginning of performance or a tender of part
performance operates as a promise to render complete performance.” Restatement (Second) of
Contracts: Acceptance of Offer Defined; Acceptance by Performance; Acceptance by Promise
§ 50 cmt. b (Am. Law Inst. 1981); see also Dixon v. Dalton, 12 P.2d 1108, 1109 (Okla. 1932)
(noting that, when one of the parties has “accepted the benefits of partial performance” of a
contract, that party cannot “escape the burdens of the contract”). So when Baker performed at
least part of the requirements of the Settlement by paying Stevens $10,000, Baker became bound
to fulfill all of its obligations under the Settlement—including those in the Release Provision.
The release therefore became binding on Baker by virtue of Baker’s performance according to
the Settlement’s terms.

       Baker next attempts to distinguish Stewart on the ground that the Oklahoma Supreme
Court in that case ultimately allowed the plaintiff’s claims to go to a jury. As a result, Baker
concludes that an unsigned contract necessarily creates a factual dispute that cannot be resolved
on summary judgment.

       This argument misreads Stewart. In that case, the contract at issue was an employment
agreement between a teacher and a city school board. The Oklahoma Supreme Court described
the facts as follows:

       The city superintendent, for two years prior to the employment here in question,
       had employed the teachers and entered into written contracts with them, and
       thereafter presented the contracts to the school board for approval. Plaintiff had
       taught one year, and was employed for a second term by the city superintendent at
       a salary previously fixed by the board. She, like all other teachers employed for
       that year, signed the written contract presented by the city superintendent, and he
       then indicated his approval by signing it as city superintendent. Under this
       employment, she entered upon her duties as teacher at the opening of the fall
       term, and taught until the 9th of November following, when she was discharged
       by the board. She had been paid her salary for the first month, and had taught
       three or four days on her second month at the time of her discharge. At the time of
No. 15-2413                 Baker Hughes, et al. v S&S Chemical, et al.             Page 12

       her discharge, the contract was still held by the city superintendent and had never
       been presented to the school board for approval.

230 P. at 505.

       After her discharge, the plaintiff in Stewart sued to recover one month of salary that she
was allegedly owed. Id. at 504. The school board defended on the basis that the employment
agreement was not binding because the contract had not been signed by the board and the parties
had not performed according to the agreement. Id. at 505. In particular, the board argued that
any earlier payment to the teacher had been made without the board’s knowledge or approval,
such that those payments did not constitute acceptance through performance.            Id.    (“It is
contended by the defendant that plaintiff’s evidence did not show . . . that the one month’s pay
which she had received was made with the knowledge of the school board or any of its
members.”). The plaintiff, in contrast, contended that the board had in fact “recognized her
employment by authorizing her to be paid one month’s salary.” Id. Based on these contentions,
a factual dispute existed regarding the board’s knowledge, making a trial necessary to resolve the
case. See id.

       The present case presents no analogous factual conflict. Baker itself transmitted the draft
of the Settlement to Stevens, received a copy of the Settlement signed by Stevens and Giles, and
undisputedly paid Stevens the $10,000 specified in the Settlement. Thus, unlike the school board
in Stewart, Baker unquestionably knew of and approved each step that gave rise to the contract at
issue. There accordingly exists no genuine dispute regarding the parties’ knowledge that would
preclude summary judgment.

       3.        Giles’s billing records do not create a genuine dispute of material fact

       Baker next argues that Giles’s billing records preclude summary judgment because they
create uncertainty about the exact terms of the Settlement. This argument relies on (1) records
from February 16, 2000 to April 18, 2000, and (2) records from December 24, 1999 to January
20, 2000.

              a. Records from February through April

      Baker first cites Giles’s billing records from February through April of 2000:

       Baker notes that, based on these records, Giles received the Settlement with “All Changes
made” on March 30, 2000.         The following day, however, Giles allegedly made additional
changes, as indicated by the reference to “[r]eview final changes to release” on March 31.
Likewise, Baker contends that Giles made further changes to the Settlement on April 7, 2000,
relying on the notation that he “[r]eview[ed] and approve[d] last changes to release.” Baker thus
argues, based solely on Giles’s billing records, that the parties were engaged in ongoing
settlement negotiations. The district court, according to Baker, therefore erred in concluding that
the Settlement was a valid contract because the parties’ continuing negotiations might have
resulted in alterations to the terms of the parties’ agreement that were not reflected in the March
30 Settlement.

       We find this argument unpersuasive. Baker speculates that the parties might have entered
into a contract different than the Settlement, but offers no documentary evidence of either a draft
or finalized version of another purported contract. In addition, the district court specifically
noted that Baker’s in-house counsel admitted during his deposition that he did not have “any
factual support” for the contention that the Oklahoma lawsuit was resolved on terms different
than those set forth in the Settlement.       Baker accordingly failed to come forward with
“significant probative evidence,” see Ondo v. City of Cleveland, 795 F.3d 597, 603 (6th Cir.
2015) (citation omitted), indicating that there exists a genuine dispute of material fact with
regard to the Settlement’s validity.

       Moreover, the billing records that Baker cites do not support the inferences that Baker
draws. Baker relies on the entries for March 31 and April 7: “Review final changes to release”
and “Review and approve last changes to release.” These entries, according to Baker, indicate
that additional changes were made to the Settlement after Giles received it from Baker’s
attorney.

       The timing of relevant events, however, does not support Baker’s argument. Giles
received the Settlement on March 30, 2000. One day later, Giles and Stevens signed it. Giles’s
statement that he “[r]eview[ed]” the final changes on March 31 thus reflects nothing more than
Giles discussing the March 30 draft with his client before he and Stevens both signed the draft.
The entry does not indicate that any new or additional changes were made.
No. 15-2413                Baker Hughes, et al. v S&S Chemical, et al.              Page 15

       One week then passed before Giles faxed the signed copy of the Settlement to Baker.
During this time, there are no entries in Giles’s records showing that Giles was communicating
with opposing counsel or actively altering the Settlement. Giles’s entry for April 7 thus does not
refer to any new or additional changes to the Settlement as received from Baker on March 30,
2000. Instead, the entry indicates only that Giles reviewed the changes that had previously been
made one last time before his client accepted Baker’s offer by returning the signed copy of the
March 30 final draft. Giles’s records, in other words, simply reflect his caution in reviewing and
approving the March 30 final draft before he committed himself and his client to its terms.

       Indeed, if Giles had been actively adding or negotiating new terms, the record indicates
that he would have written as much. Giles’s entries in December 1999 and January 2000 include
the following:    (1) “Work on settling case. . . . relay same to client and discuss same,”
(2) “Teleconference with Steve [Broussard] re client’s counter offer. Discuss same,” and
(3) “Talk to defense re their counter offer.” These records show that, when Giles was actively
involved in settlement negotiations, he recorded his communications about those negotiations.
That Giles did not record any such communications in the period from March 30 to April 7 of
2000 thus supports the conclusion that there were no continuing negotiations or other changes to
the Settlement during that time. As a result, Giles’s references to the “changes” in his March 31
and April 7 billing entries can best be interpreted as referring only to his review of changes that
were previously made. The entries do not indicate that Giles changed the terms of the March 30
draft before he accepted those terms by faxing the signed copy of the Settlement to Baker.

       In addition, even if Giles had made subsequent changes to the Settlement, the changes
would have been immaterial. This is because, as noted above, a response to an offer that
contains different or additional terms functions as a counteroffer that the original offeror may
either accept or reject. Midwest Eng’g & Constr. Co. v. Elec. Regulator Corp., 435 P.2d 89, 96
(Okla. 1967). Thus, even if the draft of the Settlement that Giles faxed to Baker on April 7, 2000
contained new or additional terms as compared to the draft of the Settlement that Giles received
on March 30, 2000, the later draft functioned as a counteroffer. See id. Baker then accepted that
counteroffer by performing according to the terms of the contract, with the result that the April 7,
2000 draft of the Settlement became a binding contract between Baker and Stevens. That draft,
No. 15-2413                Baker Hughes, et al. v S&S Chemical, et al.             Page 16

moreover, undisputedly includes the Release Provision, so even if we accept Baker’s contention
that Giles’s records reflect continued settlement negotiations, Baker is still bound by the Release
Provision. The district court therefore did not err in granting summary judgment on the ground
that Baker had released Stevens from his confidentiality obligations.

               b. Records from December and January
       Baker next cites Giles’s billing records from December 1999 and January 2000:

                   Legal Work. Work on settling case.                    0.25

       These records indicate that the parties were negotiating a settlement of the Oklahoma
lawsuit as early as December 1999. Baker then notes that the entry for January 20, 2000 reads
“Notify Court of Settlement.” This entry, according to Baker, establishes that the Oklahoma
lawsuit was settled as of that date. In addition, Baker observes that Giles’s records from this
time period do not reflect any discussions about a release of claims or obligations. Baker thus
contends that the parties settled the Oklahoma lawsuit in January 2000 and did so without any
release of Stevens from his confidentiality obligations.
No. 15-2413                   Baker Hughes, et al. v S&S Chemical, et al.            Page 17

       This argument suffers from two flaws. First, Baker raised this argument only in its reply
brief. The argument is accordingly waived. See United States v. Abboud, 438 F.3d 554, 589 (6th
Cir. 2006) (“An argument first presented to the Court in a reply brief is waived.”); Wright v.
Holbrook, 794 F.2d 1152, 1157 (6th Cir. 1986) (“Since defendant was deprived of an
opportunity to address the issue by plaintiff’s failure to raise this issue in his original brief, we
will consider the issue waived.”).

       Second, Baker’s argument fails on the merits. Even if the parties had reached an oral
agreement or a settlement in principle in January 2000, Giles’s later records—the same records
that Baker itself cites in its opening brief—unambiguously indicate that the parties continued to
refine the terms of their agreement in February and March of 2000. And those records, as
analyzed above, show that the parties did not finalize their agreement (by Stevens dismissing his
lawsuit after receiving payment from Baker) until the Settlement was circulated. This pattern of
notifying the court of a tentative settlement, to be followed by putting the agreement in writing,
is actually quite the norm.

       In addition, Oklahoma law expressly provides that the parties to a contract may
subsequently alter its terms. Okla. Stat. tit. 15, §§ 236-37. Thus, even if Baker and Stevens
originally settled the case without including the Release Provision, that original agreement does
not preclude the parties’ later consent to the terms of the Settlement.

C.     The district court did not commit reversible error in declining to strike Giles’s
       declaration and billing records

       We next turn to Baker’s arguments based on the Federal Rules of Civil Procedure.
Summary judgment in this case was based in part on Giles’s billing records and on a declaration
in which Giles described the course of settlement negotiations between Baker and Stevens.
Baker argues that the district court should have excluded these documents under Rule 26(a)(1)
and (e), Rule 37(c)(1), and Rule 56(c)(4) of the Federal Rules of Civil Procedure.

       1. Rule 26(a)(1) and (e) and Rule 37(c)(1)

       Rule 26(a)(1) requires parties to disclose information regarding “each individual likely to
have discoverable information . . . that the disclosing party may use to support its claims or
No. 15-2413                  Baker Hughes, et al. v S&S Chemical, et al.            Page 18

defenses.” Fed. R. Civ. P. 26(a)(1)(A)(i). In addition, Rule 26(e) requires a party to supplement
its disclosures “if the party learns that in some material respect the disclosure or response is
incomplete or incorrect, and if the additional or corrective information has not otherwise been
made known to the other parties during the discovery process or in writing.” Fed. R. Civ. P.
26(e)(1)(A). A party failing to comply with these rules “is not allowed to use” the information or
person that was not disclosed “on a motion, at a hearing, or at a trial, unless the failure was
substantially justified or is harmless.” Fed. R. Civ. P. 37(c)(1).

       Baker asserts—and Defendants concede—that Giles and his records were not included in
Defendants’ initial disclosures under Rule 26(a)(1). As a result, Baker contends that Giles and
his records should have been excluded from the district court’s consideration under Rule
37(c)(1).

       In most cases, Baker’s argument would carry significant weight. See Sexton v. Uniroyal
Chem. Co., 62 F. App’x 615, 616 n.1 (6th Cir. 2003) (“Rule 37 is written in mandatory terms and
is designed to provide a strong inducement for disclosure of Rule 26(a) material.” (citation and
internal quotation marks omitted)). The particular facts of the current case, however, make
Baker’s argument unconvincing.

       To start with, Defendants’ counsel explain that they did not learn of Giles’s relevance to
the case at hand until they received a draft of the Settlement (from Baker itself) on February 27,
2015, more than one month after the January 14, 2015 date on which the parties’ disclosures
under Rule 26(a)(1) were due. Their failure to list Giles at the time of the original disclosures is
thus fully understandable.

       Baker next argues that, even if Defendants had a justifiable reason not to identify Giles in
their initial disclosures, Defendants nonetheless should have supplemented their initial
disclosures in accordance with Rule 26(e). Their neglecting to do so, according to Baker, should
have resulted in the exclusion of Giles’s declaration and records under Rule 37.

       Baker’s argument is unavailing because the specific facts of this case demonstrate that
Defendants did in fact comply with Rule 26(e). That Rule, as noted above, requires a party to
supplement its initial disclosures only if the new information “has not otherwise been made
No. 15-2413                Baker Hughes, et al. v S&S Chemical, et al.               Page 19

known to the other parties during the discovery process.” Fed. R. Civ. P. 26(e)(1)(A). Here,
Giles and the information about his role in the settlement negotiations had in fact “otherwise
been made known” to Baker. First, Baker itself produced the Settlement document that first
alerted Defendants’ counsel to Giles’s relevance to the present lawsuit. Baker thus had access to
the very document indicating that Giles played a key role in negotiating the Settlement. Second,
Defendants asserted in their answer to Baker’s second amended complaint that the Settlement
barred Baker’s claims. They also included as an exhibit the Settlement document signed by
Stevens and Giles. Finally, both Giles himself and the negotiations surrounding the Settlement
were discussed during a deposition of Baker’s in-house counsel that took place well before the
discovery deadline.

       The discovery process in this case consequently revealed that (1) Giles was a central
figure in the settlement negotiations between Baker and Stevens, and (2) Giles would clearly
have information relevant to the parties’ claims or defenses. Giles and his role in this case were
accordingly “otherwise . . . made known to [Baker],” so Defendants did not violate either Rule
26(a)(1) or Rule 26(e).

       Baker counters that the disclosure of Giles was insufficient because Defendants allegedly
did not provide an explicit statement that they intended to rely on Giles and his records in
moving for summary judgment. But Baker cites no binding authority for the proposition that
Rule 26(e) requires such an explicit statement and, in any event, this alleged deficiency would
not change our disposition of this issue. This is because Rule 37(c)(1) calls for the exclusion of a
witness as a sanction for violating Rule 26(e) only if the violation was not “substantially justified
or . . . harmless.” Fed. R. Civ. P. 37(c)(1).

       For the reasons previously discussed, Baker was plainly aware of Giles’s role in the
negotiations resulting in execution of the Settlement. Moreover, Defendants’ assertion of the
Settlement as an affirmative defense and the deposition of Baker’s in-house counsel occurred
well before the July 30, 2015 close of discovery. Baker thus had both (1) knowledge of Giles
and his role in this litigation, and (2) ample time to depose Giles or otherwise seek discovery
with respect to Giles and his records. Any failure of Defendants to comply with Rule 26 was
therefore a “harmless” violation that did not require the district court to exclude the Giles-related
No. 15-2413                Baker Hughes, et al. v S&S Chemical, et al.             Page 20

documents. See Fed. R. Civ. P. 37(c)(1); see also Howe v. City of Akron, 801 F.3d 718, 747 (6th
Cir. 2015) (noting that a violation of Rule 26 is likely to be harmless when the opposing party
already has “sufficient knowledge” of the undisclosed information).

       2. Rule 56(c)(4)

       Baker next argues that the district court should have excluded Giles’s declaration under
Rule 56(c)(4) of the Federal Rules of Civil Procedure. That rule provides that a “declaration
used to support or oppose a motion must be made on personal knowledge” and “set out facts that
would be admissible in evidence.” Fed. R. Civ. P. 56(c)(4). Giles’s declaration purportedly did
not satisfy this rule because it contained speculation and legal conclusions that went beyond
anything that Giles “could actually know.”         Baker identifies four allegedly objectionable
statements:

       (1)        As consideration for the execution of the Final Agreement and
                  dismissal of the Case, Baker agreed to pay to Bruce Stevens the Sum
                  of Ten Thousand Dollars ($10,000).
       (2)        The Final Agreement was entered into as of March 31, 2000.
       (3)        The Final Agreement that my office received from Broussard on or
                  around March 30, 2000 was an offer . . . .
       (4)        Stevens and Baker both performed pursuant to the terms of the Final
                  Agreement.

       Baker contends that the first statement is “pure speculation as to why Baker Hughes
might have paid Stevens.” But the Settlement itself provides that, “[i]n consideration for the
execution of this Release, Baker agrees to pay to Stevens the sum of Ten Thousand Dollars
($10,000).” Thus, even assuming that Giles’s first statement is inadmissible speculation, the
statement has no bearing on the outcome of this case because the documentary evidence in the
record already reflects the substance of the statement.

       Baker next argues that the second statement is a “legal conclusion regarding if and when
a contract was formed.” The Settlement, however, is dated March 31, 2000, and the parties’
conduct, as described above, did in fact result in the formation of a contract. Again, then, other
evidence in the record is consistent with Giles’s statement, such that the statement itself is
unnecessary to resolve any issues in this case.
No. 15-2413                Baker Hughes, et al. v S&S Chemical, et al.             Page 21

       Baker then contends that Giles’s third statement is “pure speculation” about what Baker
intended to accomplish by sending the Settlement. As explained above, however, see Part II.B.2.
above, the language of the document and Baker’s action in sending it establish that the document
was an offer. Giles’s statement on this issue is thus irrelevant.

       Finally, Baker maintains that the fourth statement is also “pure speculation” about why
the parties acted the way they did. The Settlement, however, plainly calls for Baker to pay
Stevens $10,000 and for Stevens to dismiss the lawsuit. Both parties undisputedly fulfilled these
obligations, so the only reasonable inference is that the parties performed the terms of the
Settlement. As a result, Giles’s fourth statement is irrelevant.

       For these reasons, the district court’s consideration of Giles’s affidavit was not necessary
to the court’s decision to grant summary judgment in favor of Defendants. Any error in that
consideration accordingly does not require reversal. See Fed. R. Civ. P. 61 (“At every stage of
the proceeding, the court must disregard all errors and defects that do not affect any party’s
substantial rights.”); see also Brainard v. Am. Skandia Life Assurance Corp., 432 F.3d 655, 667
(6th Cir. 2005) (applying harmless-error analysis to an alleged violation of Rule 56(c)(4)’s
predecessor).

D.     The district court did not err in refusing to consider the parties’ post-settlement
       conduct when interpreting the Settlement

       Baker finally contends that the district court should have considered the interactions
between Baker and Stevens in the years following the execution of the Settlement. It observes
that, as noted above, it accused Stevens in 2002 of breaching his confidentiality obligations. In
addition, Baker explains that it reminded Stevens of his confidentiality obligations in 2008 and
2013. Stevens did not assert in response to any of these accusations or reminders that he had
been released from his obligations by the terms of the Settlement. Baker thus argues that
Stevens’s conduct amounts to a tacit admission that the parties did not consent to the Release
Provision.

       In response, Stevens points out that the interpretation of a contract under Oklahoma law
depends primarily on the language of the contract itself. When that language is unambiguous,

extrinsic evidence such as the parties’ course of conduct may not be used determine the
contract’s meaning. Pitco Prod. Co. v. Chaparral Energy, Inc., 63 P.3d 541, 546 (Okla. 2003)
(“If a contract is complete in itself, and when viewed as a totality, is unambiguous, its language
is the only legitimate evidence of what the parties intended.”). If, in contrast, the language of the
contract is ambiguous, then a court may use extrinsic evidence to interpret that language. State
ex rel. Comm’rs of Land Office v. Butler, 753 P.2d 1334, 1343 n.23 (Okla. 1987) (“Extrinsic
evidence to be used in search of the instrument’s intended meaning is admissible only when the
language used is susceptible of multiple meanings and there is a dispute between the parties as to
the intended meaning of the language in controversy.” (emphasis in original)).

       In the present case, the Release Provision of the Settlement is plainly broad enough to
encompass the confidentiality obligations imposed by Stevens’s Termination Agreement with
Baker. As a result, the district court correctly concluded that the release was not ambiguous and
that the parties’ course of conduct was accordingly irrelevant to its interpretation of the effect of
the release.

       Baker argues that this analysis is incorrect. It maintains that the proper question is not
whether the Release Provision is ambiguous, but whether the parties agreed to enter into a
contract that contained the Release Provision at all. Baker, in other words, acknowledges that it
settled the Oklahoma lawsuit, but maintains that the terms of that agreement were different than
those set out in the Settlement. And because Stevens never asserted in 2002, 2008, or 2013 that
he had been released from his obligations, the actual terms of their agreement—according to
Baker—must not have included any release.

       This argument is unavailing.       For the reasons previously explained, the Settlement
became a binding contract between Baker and Stevens when the two parties consented to its
terms through the process of offer, acceptance, and performance.           See Part II.B.2. above.
The Release Provision is therefore binding on the parties, and Stevens’s subsequent conduct does
not change the meaning of that provision. See Pitco, 63 P.3d at 546 (“If a contract . . . is
unambiguous, its language is the only legitimate evidence of what the parties intended.”).

                                    III. CONCLUSION

      For all of the reasons set forth above, we AFFIRM the judgment of the district court.
