<p style="font-family: Times New Roman; font-size: 10pt; font-variant: normal; margin: 0pt;">To the Board of Directors at large:</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family: Times New Roman; font-size: 10pt; font-variant: normal; margin: 0pt;">I am a holder of approximately 385,000 shares of Perma-Pipe (personally, for my children and for a family limited partnership). I am well aware of the results of the recent vote at the annual meeting and the rejection of the candidacy of Jerome Walker. My understanding is that the will of the shareholders is being thwarted and this is unacceptable.</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family: Times New Roman; font-size: 10pt; font-variant: normal; margin: 0pt;">The comment made by Jerome Walker on the annual meeting call that the that stock has performed well is a falsehood not supported by the facts. The Company went public at $8 in 1989 and is still at roughly $8 providing long-term shareholders with no return at all while the Board continues to receive substantial benefits, diluting shareholders year after year. I would suggest before such outlandish statements are made that you perform more effective due diligence.</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family: Times New Roman; font-size: 10pt; font-variant: normal; margin: 0pt;">As far as I am concerned, the only single significantly positive decision that has been made by the Board was the hiring of David Mansfield. David undertook significant actions to straighten out what previously was a corporate mess. The turn around has been achieved by David realigning the corporate credo and directional agenda on day one of his hiring. I have met with David many times and he has done exactly what he said he would do and has achieved the improved results that we now are witnessing.</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family: Times New Roman; font-size: 10pt; font-variant: normal; margin: 0pt;">Realizing David is approaching retirement age, the Board needs to incentivize David to stay on past retirement age and manage the improved operating results to their natural conclusion. In an absence of retaining Mr. Mansfield, the momentum risks a serious negative result, the likes of which shareholders at large will not tolerate.</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family: Times New Roman; font-size: 10pt; font-variant: normal; margin: 0pt;">I believe we all agree that Perma-Pipe's recent results and the expected continued improvement is not reflected in the stock price. Selling at a low multiple of earnings, a lack of premium to book value, a low multiple of EBITDA, etc., reflects the &#8220;micro-cap&#8221; discount that many small companies face. The Board should consider, as the improvement in earnings continues to unfold, that perhaps this Company would recognize improved shareholder value by combining with another like company at some point. The expense of maintaining a duplicative Board of Directors, auditors and other dispensable redundant costs not to mention a useful domestic NOL carry-forward, could provide benefits to a suitor If you fail to retain David, we have a majority of shareholders that will, at a minimum, call a special meeting/proxy contest to replace the entire Board of Directors with a slate of more shareholder-oriented directors. Realizing that David must also agree to stay on, not retaining him would be another failure of the Board and require an immediate proxy contest to replace the Board.</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family: Times New Roman; font-size: 10pt; font-variant: normal; margin: 0pt;">As a Delaware Corporation, your fiduciary duties are to shareholders and not ignoring what will finally drive the positive future of Perma-Pipe. While understanding your decisions currently fall under the business judgement rule, anything less than retaining the successful current management will trigger our seeking to replace the Board, In addition, please take this letter as my demand for a copy of Perma-Pipe&#8217;s charter and bylaws as well as a copy of the shareholder list mailed to the address below. You will find proof of ownership attached.</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family: Times New Roman; font-size: 10pt; font-variant: normal; margin: 0pt;">I would be happy to discuss this with a representative of the Board and express our concern that this Board may not do the right thing for shareholders by retaining David Mansfield. He has orchestrated a significant turn-around that is FINALLY bearing fruit.</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family: Times New Roman; font-size: 10pt; font-variant: normal; margin: 0pt;">Sincerely,</p>
