5. That no structure of any kind (including hunting blinds and/or deer feeders) shall be permitted within 300 feet of any public road, 200 feet of any private roadway easement or 100 feet of any property line.

6. No noxious or offensive activity shall be carried on upon any tract nor shall anything be done thereon which may be or become an annoyance or nuisance to any adjoining tract. No tract shall be maintained or utilized in such a manner as to violate any applicable statute, ordinance or regulation of the United States of America, the State of Texas, the County of Terrell, if applicable, or any other governmental agency having jurisdiction thereof.

7. Not more than one residence shall be permitted on any tract. No communal residences shall be permitted.

8. That no commercial swine operation shall be permitted.

9. PURCHASER agrees not to impede the flow of water in existing water lines that cross his property and grants ingress and egress to persons who need to maintain such water lines.

10. That no tract may be subdivided without the express written consent of the SELLER. This restriction will not prevent the Texas Veteran's Land Board (TVLB) from deeding a tract to a veteran for the purpose of a home site.

11. PURCHASER hereby authorizes SELLER and/or Assigns to charge each property owner a maintenance fee of $.50 per acre, per year, not to exceed $150.00 to improve and maintain the highway entrances, roads, wells, water lines, storage tanks and any other maintenance deemed necessary by the Property Owners Association in the Sierra Vista Ranch Subdivision.. Those tracts of land which front exclusively on a state or county maintained road will be charged a maintenance fee of $.25 per acre, per year, not to exceed $75.00. Such charge shall not be assessed against SELLER and/or Assigns. Such charge shall be made by direct billing to the property owner. If PURCHASER refuses to make said payments, PURCHASER hereby authorizes SELLER, at SELLER's option, to deduct such charge from payments made by PURCHASER, and any such charge so deducted will not be credited to the payment on the balance due on the purchase price, principal or interest. It is understood and agreed that this maintenance charge (if not paid within 60 days of billing date) shall become a lien against the tract being conveyed, permitting SELLER and/or Assigns such rights to enforce said liens as may be set forth in Sec. 51.002 of the Texas Property Code, as amended time to time.

12. That at such time as Seller may determine at his sole discretion, the Seller shall have the authority but not the obligation to notify each tract owner of the time, date, and a place of a meeting of all tract owners to be held for the purpose of organizing a Property Owner's Association. A majority of the votes of the tract owners in attendance at such meetings or by written proxy shall be sufficient to transact business at such meeting. Each tract owner, including Seller, attending or represented by written proxy at such meetings shall have one vote for each tract owned by such owner on all business to come before the meeting. Upon the creation and organization of such organization, as non-profit corporation, or otherwise, Seller shall transfer and assign to the association the current balance of the maintenance fee collected, if any. Thereafter such association shall have the power, authority and obligation to maintain the roadways of the development and collect the maintenance assessment. All such assessments upon any tract in the development shall become the personal obligation of the owners of such tract and such association is hereby granted a lien upon each lot to secure the payments of such assessments, permitting said association such rights to enforce said liens as may be set forth in Sec. 51.002 of the Texas Property Code, as amended time to time.

13. No deviation of any kind shall be permitted from these restrictions unless permission is granted in writing by the Seller.
