(“KPERS”), a Kansas governmental entity, and two affiliated entities, .K.D.F. and Pac-holder Associates, contend that the trial court abused its discretion by overruling their TexJR.Civ.P. 120a special appearances. All three assert that under principles of interstate comity, Texas is obliged to recognize the sovereign immunity of the State of Kansas and therefore to decline to exercise jurisdiction over them.
See generally United Mexican States v. Ashley,
I
KPERS is a Kansas governmental entity. Kan.StatAnn. § 74-4903 (1992). Kansas Debt Fund (“K.D.F.”) is a Kansas General Partnership, created by Commerce Bank of Topeka, Kansas, which holds securities on behalf of KPERS. Pacholder Associates, Inc., KPERS’s independent investment ad-visor, is an Ohio corporation with its principal place of business in Ohio. The Real Parties in Interest are plaintiff Texas Hydrogen Energy Corporation, a Texas corporation wholly owned as a subsidiary, and its parent, plaintiff Hydrogen Energy Corporation, a Utah corporation based in Kansas, (collectively, “Hydrogen”).
This controversy arises out of a loan KPERS made to Hydrogen in November 1989, in return for which Hydrogen executed a promissory note (“Note K”) payable to K.D.F. as KPERS’s agent. The purpose of the loan was to facilitate Hydrogen’s purchase of an oil and gas property in Andrews County, Texas, from a debtor in bankruptcy; Hydrogen used the loan proceeds to purchase another promissory note (“Note H”) from a creditor in the bankruptcy proceedings. A mortgage on the Andrews County oil and gas property secures Note H, and KPERS has secured Note K by taking a security interest in Note H and the mortgage securing it. See Tex.Bus. & Com.Code Ann. §§ 1.201(37), 9.103 & cmt. 4, 9.201 (Vernon 1991 & Supp.1994). From an earlier transaction between the parties, K.D.F. holds a $2,500,000 convertible debenture dated April 2, 1985.
In 1991, Hydrogen sought to sell the Andrews County property to UMC Petroleum Corporation. The sale fell through, Hydrogen claims, after KPERS and K.D.F. reneged on their agreement to release K.D.F.’s security interest in Note H. Hydrogen also alleges that KPERS and K.D.F. impermissi-bly conditioned the release upon Hydrogen’s payment of past due interest on the debenture.
Hydrogen filed suit against KPERS, K.D.F., and Pacholder in Andrews County on December 1991, alleging in its jurisdictional statement that the case involved the rights of creditors to mineral interests in Andrews County. Hydrogen sought damages and in-junctive relief, alleging ordinary and gross negligence, tortious interference with business relations, fraud, defamation, breach of the duty of good faith and fair dealing, and breach of fiduciary duties. Hydrogen later amended its petition to add a claim for usury.
In response, each defendant filed a special appearance. After a hearing, the trial court overruled all objections to jurisdiction. The defendants, as relators, now seek mandamus relief from the trial court’s order overruling their contest to jurisdiction.
II
Initially, we address the parties’ conflicting characterizations of the nature of Hydrogen’s suit and the basis upon which the trial court has assumed jurisdiction over rela-tors. Hydrogen argues that the trial court has exercised its
in rem
jurisdiction and that the issue presented is the right of Texans to sue in Texas courts to establish title to their land. Relators argue that Hydrogen’s suit is one for damages brought “under the guise of a suit to determine the collateral interest of K.D.F. and to restrain a foreclosure.” Hydrogen has sued for fraud, defamation and other torts, for injunctive relief, and for a declaratory judgment determining the effect of contracts between it and the Kansas entities, including the debenture, Note K, and the Note K security agreement. Hydrogen has not brought an action in trespass to try title,
see
Tex.PROp.Code Ann. §§ 22.001-22.-
*592
045 (Vernon 1984), or an action to quiet title.
See
Tex.Civ.Prac. & Rem.Code Ann. § 15.011 (Vernon 1986);
Humble Oil & Refining Co. v. Sun Oil Co.,
Furthermore, Hydrogen is the only party holding any interest in the realty located in Andrews County. The only interest that KPERS and K.D.F. hold is a security interest in “[Hydrogen’s] notes, instruments, general intangibles, deeds of trust, guaranties, financing statements, mortgages, security agreements ... and all extensions thereof.” The Note K collateral includes Note H and any mortgage securing it, but the Andrews County property is not itself collateral for Note K.
Hydrogen’s lien is not governed by Article Nine of the Uniform Commercial Code because the collateral securing Note H is real property. Tex.Bus & Com.Code Ann. § 9.104(10). KPERS’s Note K hen, however, is an Article Nine security interest because, under Tex.Bus. & Com.Code Ann. § 9.102(c), “the application of this chapter to a security interest in a secured obligation is not affected by the fact that the obligation is itself secured by a transaction or interest to which this chapter does not apply.” The relevant KPERS security interest for present purposes is a security interest in an instrument, see Tex.Bus. & Com.Code Ann. §§ 3.104, 9.105(a)(9), 9.106, not real property. See Tex.Bus. & Com.Code Ann. § 9.102(c) & cmt. 4. The Note K security interest and the remedies it affords 1 enable KPERS and K.D.F, in the event of foreclosure, to acquire Note H and the associated mortgage interest in Andrews County realty. 2 But Hydrogen is the only party that currently holds a real property interest.
Ill
KPERS is a Kansas statutory entity, a “body corporate and instrumentality” of the Kansas government, Kan.StatAnn. § 74-4903 (1992), created to manage and invest the retirement savings of Kansas state employees. Analogous Texas entities are the Employees Retirement System of Texas, see Tex.Gov’t Code Ann. §§ 811.001-815.501 (Vernon 1994), and the Teacher Retirement System of Texas. See Tex.Gov’t Code Ann. §§ 821.001-825.511 (Vernon 1994). When Kansas created its public employee retirement system, it conditionally waived its sovereign immunity to lawsuits, but required all actions “directly or indirectly” against the system to be filed in Shawnee County, Kansas. Kan.Stat.Ann. § 74-4904 (1992 & Supp. 1993).
A
Mandamus issues to correct a clear abuse of discretion when there is no adequate remedy by appeal.
Walker v. Packer,
*593 CHL points out our decision in United Mexican States v. Ashley,556 S.W.2d 784 (Tex.1977), as support for its claim that mandamus review of a special appearance is appropriate. However, Ashley involved the issue of sovereign immunity, implicating comity and foreign affairs concerns not present in the usual special appearance.
Canadian Helicopters,
This comity exception, enunciated in Ashley and confirmed in Canadian Helicopters, is explained by the risk of harm to interstate and international relations likely to occur if a Texas trial court erroneously exercises jurisdiction over another sovereign. Such potential harm plainly goes beyond the additional time and expense ordinarily required to pursue an appeal, and beyond the immediate interests of the parties to the suit. Therefore, we reaffirm that an appeal does not provide an adequate remedy in this context.
The “clear abuse of discretion” standard is a function of the distribution of decision-making authority among the trial and appellate courts. As we said in
Walker,
“with respect to resolution of factual issues or
matters committed to the trial court’s discretion,
for example, the reviewing court may not substitute its judgment for that of the trial court ... [o]n the other hand, review of the trial court’s determination of the legal principles controlling its ruling is much less deferential.”
Walker,

Whether to recognize Kansas’s sovereign immunity in this case presents an issue of interstate comity, unrelated to the Full Faith and Credit Clause. In
Nevada v. Hall,
It may be wise policy, as a matter of harmonious interstate relations, for states to accord each other immunity or to respect any established limits on liability. They are free to do so.

Comity is a doctrine grounded in cooperation and mutuality. United States courts defer to the sovereignty of foreign nations according to principles of international comity.
See Saudi Arabia v.
Nelson, - U.S. -, -,
Arguing that Texas should not extend comity in this case, Hydrogen directs our attention to two cases in which other states have declined to extend comity to Texas. In the first of these cases,
Peterson v. Texas,
[W]here the injured party is a citizen of this state, injured in this state and sues in the courts of this state, there is no immunity, by law or as a matter of comity, covering a sister state [sic] activities in this state.
Id. at 243. The appellate court did not, however, expressly consider whether Colorado should assess Texas’s liability, if any, under the Texas Tort Claims Act. Tex.Civ. Prac. & Rem.Code Ann. §§ 101.001-101.109 (Vernon 1986 & Supp.1994). Nor did the Colorado court consider the effect of a mandatory venue statute.
In
Ehrlich-Bober & Co. v. University of Houston,
We reject Hydrogen’s argument that, in deciding whether to recognize Kansas sovereignty, we should consider whether some jurisdiction other than Kansas has exercised jurisdiction over the State of Texas in a manner that violates recognized principles of interstate cooperation and mutuality. The issue here is whether
Kansas
has extended comity and recognized the sovereignty of Texas and other states.
See generally Head v. Platte County, Missouri,
*595 IV
A
In the absence of a clear indication to the contrary, we will treat Kansas as a cooperative jurisdiction. Texas will extend comity to the law of a cooperative jurisdiction so long as that law does not violate Texas public policy.
Robertson v. Estate of McKnight,
The Kansas mandatory venue statute does not violate any Texas public policy. Indeed, Texas has similar statutes that serve the same purpose the Kansas statute advances— minimizing the litigation costs that taxpayers must bear by providing state agencies with a convenient venue in which to litigate. 5
Hydrogen argues that Texas public policy would suffer if a Kansas court were to determine the effect of the Note K security interest. Assuming that choice of law principles would require Kansas to apply the same law as Texas to this transaction, Hydrogen cannot claim prejudice solely on the ground that a different court will apply the same law. Moreover, Kansas, like Texas, has adopted the Uniform Commercial Code. See Kan.Stat.Ann. §§ 84-1-101 to 84-10-102 (1983 & Supp.1993). To the extent the UCC governs, the legal standards will be as familiar there as they are here.
Nor is the fact that Hydrogen may find litigation in Kansas less convenient or more expensive sufficient to offset Texas’s interest in promoting interstate comity. The burden imposed on Hydrogen is little different from the burden our own legislature has placed on Texas citizens; mandatory venue statutes require our own citizens, even those who live as far away as El Paso, Beaumont, Brownsville, or Dalhart, to pursue certain claims against state governmental entities in Travis County.
Moreover, the only Texas plaintiff in this case is Texas Hydrogen Energy Corporation, which is a subsidiary of Hydrogen Energy Corporation. Hydrogen Energy Corporation, which is also a plaintiff, has its headquarters in Kansas. Under these circumstances, a Kansas venue appears to be as convenient as one in Texas.
B
Hydrogen further argues that comity is not appropriate in this case because KPERS is engaged in commercial rather than governmental activity. We disagree. Initially, it is not clear to us that investing the retirement savings of state employees can be categorized as purely, or even primarily, a commercial activity. Kansas is not, for example, operating a mutual fund in which the general public may invest. Rather, KPERS exists to permit the Kansas government to fulfill its governmental function as a public employer.
Hydrogen cites
21 Turtle Creek Square, Ltd. v. New York State Teachers’ Retirement Sys.,
Hydrogen’s apparent source for this commercial-governmental dichotomy is the law of international sovereign immunity. The doctrine of “restrictive sovereign immunity” is a concept that has developed in United States foreign affairs largely since 1952.
See Verlinden B.V. v. Central Bank of Nigeria,
461 U.S.
480, 486-88 & nn. 9-10, 103

United Mexican States,
Y
While we have decided that KPERS is entitled to sovereign immunity protection, we must still determine whether K.D.F. and Pacholder may benefit from the sovereign immunity of Kansas. Unlike KPERS, however, K.D.F. and Pacholder are not Kansas governmental entities.
KPERS, K.D.F., and Pacholder point to the Kansas statute, which requires that all lawsuits “directly or indirectly” against KPERS must be brought in Shawnee County. Kan.Stat.Ann. § 74-4904 (1992 & Supp. 1993). Certainly, this language prevents litigants from circumventing the mandatory venue provision by suing KPERS agents or employees in their individual capacities for carrying out instructions of their principal or employer. The same statute further provides “trustees, officers, employees, and agents [of KPERS] shall not be personally hable for acts of the system unless such person acted with willful, wanton or fraudulent misconduct or intentionally tortious conduct.” Id. However, we decline to interpret the “directly or indirectly” statutory language so broadly that any suit is barred outside Shawnee County if a remote possibility exists that some defendant might sue KPERS for contribution. The appropriate distinction between lawsuits “indirectly” against KPERS and legitimate actions against a KPERS agent or employee in his or her individual capacity is found in the statutory language quoted above — whether the actions complained of are “acts of the system.” Id.
We find further guidance in the Kansas Tort Claims Act and the Texas Tort Claims Act as they apply to state employees sued as individuals. The Kansas Act waives all immunity subject to express exceptions. Kan.Stat.Ann. §§ 75-6103, 75-6104 (1989 & Supp.1993). Conversely, the Texas Act constitutes a selective waiver, leaving immunity intact except to the extent waived. Tex.Civ. Prac. & Rem.Code Ann. § 101.025 (Vernon 1986); see also id. §§ 101.021,101.0215,101.-023-101.024, 101.051-101.063 (Vernon 1986 & Supp.1994). Both acts provide that the respective state will be hable for acts or omissions of officials or employees in the performance of the duties of office. Tex.Civ.Prac. & Rem.Code Ann. §§ 104.001-104.003, 108.-001-108.003 (Vernon Supp.1994); Kan.Stat.Ann. § 75-6109 (1989).
However, indirect liability for the acts of employees is limited in both states. In Texas, a governmental entity’s limited liability is
*597
derivative of the employee’s official immunity. The Texas Tort Claims Act, Tex-Civ.PRAC. & Rem.Code Ann. §§ 101.026, 104.-008 (Vernon 1986), leaves an employee’s common law official immunity intact, and chapters 104 and 108 of the Tort Claims Act provide for indemnification of the employee only for “actual damages, court costs, and attorney’s fees adjudged against” the employee. Tex.Civ.PRAC.
&
Rem.Code Ann. §§ 104.001-104.008, 108.001-108.003 (Vernon 1986 & Supp.1994). Official immunity in Texas is an affirmative defense to negligence claims against state employees that applies when employees exercise discretion in good faith while acting within the scope of their official authority.
City of Lancaster v. Chambers,
The Kansas statute collapses the official immunity defenses of the employee and the state into a single statutory exception: “A governmental entity or an employee acting within the scope of ... employment shall not be liable for ... performance or the failure to exercise or perform a discretionary function.” Kan.Stat.Ann. § 75-6104(e) (1989 & Supp.1993);
Robertson v. City of Topeka,
Thus, in either state, indirect liability on the part of the state will arise from the performance of ministerial functions by a state employee under the control or direction of the state, and not from (1) discretionary acts of the employee, (2) acts of independent contractors, or (3) intentional, grossly negligent, fraudulent, or malicious conduct by the employee. We think it is reasonable to hold that K.D.F. and Pacholder can benefit “indirectly” from the sovereign immunity of Kansas, subject to these same principles. Therefore, an agent of KPERS will not be subject to Texas jurisdiction in an individual capacity for performing essentially ministerial functions under the control and direction of KPERS.
K.D.F. operates solely upon the direction of KPERS, and exercises no discretion in its activities. For jurisdictional purposes, we hold that K.D.F. and KPERS are not distinguishable from one another; a lawsuit against one is a lawsuit against the other.
Pacholder, however, is an Ohio corporation that serves as an investment advisor to KPERS. Pacholder operates as an independent contractor. Its activities necessarily involve considerable discretion. Thus, its role is more in the nature of advising KPERS how to proceed, rather than being subject to the direction and control of KPERS.
Pacholder also points out that it has an indemnity agreement with KPERS, and argues that any lawsuit against it is a lawsuit “indirectly” against KPERS. While damages awarded in a lawsuit against Pacholder may ultimately be paid in full by the Kansas government, this fact alone does not require Texas to decline jurisdiction over Pacholder. While sovereign immunity protects the activities of government entities, no sovereign is entitled to extend that protection ad infini-tum through nothing more than private contracts. Pacholder is not entitled to sovereign immunity protection unless it can demonstrate its actions were actions of the Kansas government, executed subject to the control of KPERS. Of course, Texas’s jurisdiction over Pacholder also necessarily depends on *598 the existence of minimum jurisdictional contacts under the Texas long-arm statute.
For the reasons stated, we conditionally grant the petition for writ of mandamus filed by K.D.F. and KPERS. We deny Pacholder’s petition without prejudice so that it may present its special appearance to Judge Rex for reconsideration in light of this opinion. The clerk is directed to issue the writ only in the improbable event that Judge Rex does not vacate his orders overruling the special appearances of KPERS and K.D.F.
Notes
. Article Nine remedies permit KPERS to foreclose on Note H “when [the] debtor is in default,” subject to the debtor's right of redemption. See Tex.Bus. & Com.Code Ann. §§ 9.501(a), 9.505(a), 9.506.

The Note K security interest may also affect Hydrogen’s ability to assign or extinguish the Note H mortgage interest, and issues of perfection and priority are beyond the scope of this opinion.

Arrayed against that policy which essentially serves administrative convenience, is New York’s recognized interest in maintaining and fostering its undisputed status as the pre-emi-nent commercial and financial nerve center of the Nation and the world.... Indeed, access to a convenient forum which dispassionately administers a known, stable, and commercially sophisticated body of law may be considered as much an attraction to conducting business in New York as its unique financial and communications resources.
