Attention:     Gary Ampulski
                    Chief Executive Officer

Dear Mr. Ampulski:

In last Thursday’s investor conference call I expressed my shock (as a significant Tab stockholder) that, after ninety days in the CEO’s seat and despite what you described as “many interactions with the Board,” you have no Board-approved plan to bring Tab immediately to a break even operating level and thereafter to profitability. On the conference call, you noted that such a plan wasn’t “rocket science,” and I agree.

The time to implement a turnaround plan is now. Tab has suffered aggregate operating losses of $23.4 million over the last twenty one months. As a significant Tab stockholder, I insist that the bleeding be stopped now. You must act as though Tab’s cash position did not exist. The business owes it owners and other stakeholders a profit, not further erosion of its asset base.

I recommend that your plan include the following actions:

1. Sell Company-owned dealers. I agree that Tab's manufacturing operations are in good shape. However, I cannot agree that running a dual channel distribution system will be effective. You can remedy the current suboptimal situation by taking one of the following steps:
   
   

   a) Sell or transfer the direct Company-owned dealer operations to a geographically adjoining Tab independent dealer; or

   
   

   b) Sell or transfer the direct Company-owned dealer operations to the branch manager; or

   
   

   c) Take other immediate action to make each Company-owned dealer profitable.

   
   

   I am not aware of any small, profitable specialty office products manufacturers that run their own dealerships. Successful dealerships require entrepreneurial management, which is unlikely to be found in any corporate environment. You do not want to lose the revenue stream, but you must reduce the fixed costs of the direct operations.

2. Reduce all non-essential corporate headquarter costs. The Company has indicated that moving the headquarters from San Jose to Chicago will save it $1 million per year. I cannot understand why all corporate operations cannot be located in Mayville, which would enable the Company to save all travel, communication and other costs related to having a headquarters that is remote from its main facility. Customers and dealers will travel to Mayville, as they have for the past several decades.
   
   

   Mayville is about fifty miles northwest of Milwaukee, which is a very attractive city (recently found, in fact, by a national publication to be the No. 1 most underrated city in the United States) with beautiful northern suburbs. The notion that you cannot attract management talent to work in Mayville, living either in the Mayville area or in suburban north Milwaukee, is based on a specious, big city attitude. Having a remote office is clearly a waste of corporate assets that will produce no incremental return to Tab’s stockholders or its customers.

3. Consolidate all Wisconsin operations into your main manufacturing facility and sell your smaller facility. There is no reason that you need two manufacturing sites north of Milwaukee. Your operations team can consolidate all of Tab’s metal and paper operations into your main facility, which would further reduce Tab’s operating costs. While it would require some capital investment, this would be offset by the cost savings and the proceeds from the sale of Tab’s smaller, Lomira facility.
   
   
4. Reduce other costs until Tab’s current Selling, General & Administrative cost to sales ratio is less than 30%. Tab needs to be profitable TODAY. The expense side of the business has to fit the size of the business as it stands today, not as it may be two years from now. Your current run rate is $100 million annualized, based on bookings of $25 million for the latest quarter, which you indicated on the conference call. You have to operate profitably at your current, not future, run rate.
   
   

   The strategy of deferring expense reductions has already failed, to the tune of $23.4 million in aggregate operating losses in the last twenty one months. You have to take actions as though Tab had no money. The cash on Tab’s balance sheet has given Tab’s management the ability to squander $23.4 million by ducking the hard business decisions that should have been made two years ago.

   In Thursday’s conference call you stated that you have had the experience of working for, and owning stock in companies with CEOs that destroyed shareholder value and that, from the shareholders’ point of view, “it didn’t make [your] day.” The ongoing destruction of shareholder value at Tab through operating losses and dissipation of assets doesn’t make my day, either.

5. Change the commission payment system so that dealers and salespeople get paid after the Company gets paid. Tab’s current system of paying commissions upon shipment has led to accounts receivable that are, on average, between sixty and ninety days old. Everyone involved in the selling and manufacturing process has to have an economic incentive to collect the money owed to Tab. Initially many people will complain, but payment of commissions after collection of an invoice is standard practice in the specialty office products industry.

My advice and strong interest is that you do not wait any longer. Take action NOW. Otherwise, it appears that Tab will continue to incur losses and squander its cash reserves by the end of the year.

Very truly yours,

HAMILTON SORTER CO., INC.
