..Object reference not set to an instance of an object.. Error occuring for a public static script variable.

I'm trying to get a middle-man script to read a public float variable from a public static script, then push it to a UI text box attached to the middle-man script. I can get the public static script to debug.log the variable without a problem.

Here's the Middle-man or interpretor script that the error occurs on.

 using UnityEngine;
 using System.Collections;
 using UnityEngine.UI;
 
 public class UnitImportCombat : MonoBehaviour {
 
     public Text button1;
 
     // Use this for initialization
     void Start () {
         button1.text = "01. " + Unit01Data.stats.health;
         Debug.Log(Unit01Data.stats.health);
     }
     
 }

Here's the Unit01Data script... I reduced amount of clutter on it, but please follow up if you think the extra bits are important. They're save and load data stucture stuff.

 using UnityEngine;
 using System.Collections;
 using System;
 using System.Runtime.Serialization.Formatters.Binary;
 using System.IO;
 using UnityEngine.UI;
 
 
 public class Unit01Data : MonoBehaviour {
     public static Unit01Data stats;
 
 
     public float health;
     public float mana;
     public float exp;
