Based on our review and the above information as provided by Telecad Wireless, it is our opinion the City of Prior Lake can proceed with approval of this phase of the project the remaining comments have been addressed to the satisfaction of the city. Following approval by the City a pre-construction meeting must be scheduled by the tenant to include the City, SEH, the contractor and Sprint representatives prior to commencement of project construction. If you have any questions regarding our comments, please contact me directly at 651.765.2971.

Ot. 41111 C November 26, 2012 Site Number: MS14XC883 Site Name: Prior Lake Water Tank Site Address: 4741 Tower St, Prior Lake, MN 55372 Structure Type: Existing Water Tower As requested, Selective Site Consultants, Inc. (SSC) has reviewed documents regarding the subject site in order to assess its structural capability to support the proposed antenna loadings. Documents reviewed include SSC Rev 0 drawings dated 09-10-12 and current photos. 1. Interim Configuration: • Elevation 80': (2) existing CDMA antennas, (1) KMW ET-X-TS-70-15- 62-18-IR-RD antenna, (1) RRH-C2A 800 MHz RRU, and (1) RRH-P4 1900 MHz RRU per sector mounted on frames attached to the leg of the existing water tower corresponding to azimuths of 20 and 260 degrees. • Elevation 80': (1) Andrew VHLP2-18 microwave dish mounted on a frame attached to the leg of the existing water tower corresponding to an azimuth of 312 degrees. • Elevation 90': (2) existing CDMA antennas, (1) KMW ET-X-TS-70-15- 62-18-IR-RD antenna, (1) RRH-C2A 800 MHz RRU, and (1) RRH-P4 1900 MHz RRU per sector mounted on a frame attached to the leg of the existing water tower corresponding to an azimuth of 120 degrees. 2. Final Configuration: • Elevation 80': (1) KMW ET-X-TS-70-15-62-18-IR-RD antenna, (1) RRH- C2A 800 MHz RRU, and (1) RRH-P4 1900 MHz RRU per sector mounted on frames attached to the leg of the existing water tower corresponding to azimuths of 20 and 260 degrees. • Elevation 80': (1) Andrew VHLP2-18 microwave dish mounted on a frame attached to the leg of the existing water tower corresponding to an azimuth of 312 degrees. • Elevation 90': (1) KMW ET-X-TS-70-15-62-18-IR-RD antenna, (1) RRH- C2A 800 MHz RRU, and (1) RRH-P4 1900 MHz RRU per sector mounted on a frame attached to the leg of the existing water tower corresponding to an azimuth of 120 degrees. 9900 WEST 109TH STREET,SUITE 300 n 913.438.7700 OVERLAND PARK, KANSAS 66210 1913.438.7777 sSt..US.c(»t The proposed antennas are to be mounted on existing frames attached to the legs of the existing water tower and at the same centerline as the existing antennas. The weight of the antennas and RRUs will be insignificant when compared to the gravity loads carried by the water tower. The additional loads imparted to the water tower by the proposed antennas will create less than a 5% increase in stresses. Per the IBC code section 3403 the structure will be adequate for the proposed loads. The existing frames will also be adequate to support the wind imparted by the proposed antennas. Assuming that the existing structure is built per all applicable codes and adequately supports the existing loads it is the opinion of SSC that the existing structure will be 1 adequate to support the proposed interim and final Sprint installation. Thank you, and please feel free to contact us if you require further information. Sincerely, 2r4ad aiv R .' Michael L. Owens, P.E.
