 EXHIBIT 1 
 1. Certain Litigation or Potential Litigation Matters. 
 a. On December 10, 2007, the
County of Riverside, California, brought a Complaint In Eminent Domain against the owner of certain real property on which an antenna structure, on which Administrative Borrower is a tenant, is located (County of Riverside v. Royal Street
Communications, et al., Case No. 487075 (Super. Ct. of Riverside Cty.)). As a tenant, Administrative Borrower was named as a defendant. The County seeks to take the underlying property for use as part of a sports complex. The
Complaint was not served on Administrative Borrower until May 2, 2008. Administrative Borrower has identified counsel and due to pending negotiations with the plaintiff, County has not been required to respond to the summons. On August 7,
2008, the court entered an Order for Prejudgment Possession of the Property in favor of the County, which was entitled to take possession of the property on September 2, 2008. The County and Administrative Borrower have finalized a Stipulation
Regarding Assumption Of Lease that would substitute the County as the landlord under the Master Lease Agreement with the tower owner and there would be no changes to Administrative Borrower’s existing site lease agreement with the tower owner.
The Court entered an order approving the fully executed Stipulation on October 20, 2009. 
 b. On June 18, 2008, Administrative
Borrower was served with a summons as an additional defendant in the case of Jason Ortiz v. Southern California Edison, et al., Case No. RIC 485986 (Super. Ct. of Riverside Cty.), a personal injury action by a former employee of
Clotworthy Construction, Inc., with which Administrative Borrower has a construction contract. Administrative Borrower is being defended in this matter by LaFollette Johnson DeHaas Fessler and Ames, which was hired by Administrative Borrower’s
insurance carrier, Travelers Insurance, to defend Administrative Borrower. The case remains pending after the Court, on June 30, 2009, denied Administrative Borrower’s Motion For Summary Judgment. Pre-trial discovery continues. 

c. On July 22, 2008, Administrative Borrower was served with a summons as an additional defendant in the case of Rigoberto Chavez, et al.
v. Xiaogewn Wu, et al., Case No. BC 394867 (Super. Ct. of Los Angeles Cty.), an action by a former owner of the site on which Administrative Borrower has located a cell site claiming that the new owner had assigned its interest in
Administrative Borrower’s lease payments to the plaintiff, but had not received them. On September 22, 2008, Administrative Borrower’s counsel filed an Answer and a Cross Complaint against Wu and Chavez for, among other things,
failure to indemnify Administrative Borrower. Administrative Borrower filed an Amended Cross Complaint on October 29, 2008. Several additional cross pleadings and demurrers have been filed since that date, to which Administrative Borrower has
responded and the case remains pending and discovery has been initiated. A mediation was held in the case on March 18, 2009 and there have been periodic settlement discussions concerning the possible resolution of the case. On November 12,
2009, the parties reached a settlement agreement in principal with the Court setting a return date of December 4, 2009. Settlement agreement signatures and payments are in the process of being collected; the Court has set a Status Conference
after settlement for March 22, 2010, at which time Administrative Borrower expects the case relating to Administraitve Borrower to be fully resolved. 
  

 10 

 d. On or about August 26, 2009, Administrative Borrower was served with a summons in the case of
Ask Associates, LLC v. Royal Street Communications, LLC, Case No. 1044427 (Super. Ct. of Los Angeles Cty), an action by the landlord under a site lease entered into relating to a portion of the premises
located at 22761 Pacific Coast Highway, Malibu, California 90265-5098. The landlord is suing for breach of the lease claiming that Royal Street has improperly terminated the lease and failed to pay rent due. Administrative Borrower engaged counsel
and has now filed a general denial on October 12, 2009. Administrative Borrower settled the case and it was dismissed on February 8, 2010. 
 2. Assignment Of Certain Contracts 
 As of this date, Administrative Borrower has assigned all of the site leases and related
agreements originally entered into in the name of Administrative Borrower to its Operating Subsidiaries, Royal Street Communications California, LLC, and Royal Street Communications Florida, LLC, respectively, as required by Section 5.4 of the
Credit Agreement. However, the terms of many of those leases or other assigned agreements require that the assignor, Administrative Borrower, remain liable for the obligations under the terms of the assigned agreements. 
  

 11 

 EXHIBIT 2 
 1. Assignment Of Certain Contracts 
 As of this date, Administrative Borrower has assigned
all of the site leases and related agreements originally entered into in the name of Administrative Borrower to its Operating Subsidiaries, Royal Street Communications California, LLC, and Royal Street Communications Florida, LLC, respectively, as
required by Section 5.4 of the Credit Agreement. However, the terms of many of those leases or other assigned agreements require that the assignor, Administrative Borrower, remain liable for the obligations under the terms of the assigned
agreements.
