STOCK TRANSFER RESTRICTIONS

Any stockholder, including the heirs, assigns, executors or administrators of a deceased stockholder, desiring to sell or transfer such stock owned by him or them, shall first offer it to the corporation through the board of directors in the manner following:

He shall notify the directors of his desire to sell or transfer by notice in writing, which notice shall contain the price at which he is willing to sell or transfer and the name of one arbitrator. Notice given pursuant to this article, to be effective as such, much clearly set forth the price and the name of the arbitrator as aforesaid. Any deficiency in this regard shall render the attempted notice nugatory. The directors shall within thirty days after receipt or thirty-five days after posting whichever shall first occur, either accept the offer, or by notice to him in writing name a second arbitrator, and these two shall name a third. It shall be then the duty of the arbitrators to ascertain the value of the stock, and if any arbitrator shall neglect or refuse to appear at any meeting appointed by the arbitrators, a majority may act in the absence of such arbitrator.

After the acceptance of the offer, or the report of arbitrators as to the value of the stock, the directors shall have thirty days within which to purchase the same at such valuation, but if at the expiration of thirty days, the corporation shall not have exercised the right to so purchase, the owner of the stock shall be at liberty to dispose of the same in any manner he may see fit. Provided, however, that the foregoing restrictions on transfer shall not apply to inter-vivos or testamentary transfers to the spouse, child, spouse of child, or grandchild of the stockholder. With respect to such transfers to spouse, child, spouse of child, or grandchild, there shall be no restriction.

The Corporation shall indemnify any and all persons who may serve or who have served at any time as directors or officers or who at the request of the Board of Directors of the Corporation may serve or at any time have served as directors or officers of another corporation in which the Corporation at such time owned or may own shares of stock or of which it was or may be a creditor, and their respective heirs, administrators, successors and assigns, against any and all expenses, including amounts paid upon judgments actually and necessarily incurred by such persons in connection with the defense or settlement of any claim, action, suit or proceeding in which they, or any of them, are made parties, or a party, or which may be asserted against them or any of them by reason of being or having been directors or officers or a director officer of the Corporation, or of such other corporation, except in relation to matters as to which any shall be adjudged in any action, suit, or proceedings to be liable for his own negligence or misconduct in the performance of his duty. Such indemnification shall be in addition to any other rights to which those indemnified may be entitled under any law, by-law, agreement, vote of stockholders, or otherwise.

To whom it may concern:

Reference is made to a certain corporation, bearing the name Cambridge Technology, Inc., which was dissolved in 1979, and which had as its corporate address 275 Wyman Street, Waltham, Massachusetts.
