At the special meeting, we will ask you to vote on the merger of Indus River and Cabletron Systems, Inc. Cabletron will issue an aggregate of 4,000,000 shares of Cabletron common stock and 50,000 shares of Cabletron series C preferred stock in exchange for all of the shares of Indus River preferred stock, Indus River common stock, and all options and warrants to purchase Indus River stock. Cabletron will also reserve for issuance approximately 100,000 additional shares of Cabletron common stock and 1,100 additional shares of Cabletron series C preferred stock to be issued to holders of additional options granted in exchange for the forfeiting of acceleration rights and some options granted to some employees hired by Indus River after August 18, 2000 with Cabletron's consent. In the merger, you will receive a number of shares of Cabletron series C preferred stock and Cabletron common stock for each share of Indus River preferred stock and Indus River common stock that you own. The exact exchange rate will not be known until five trading days before the closing date of the merger because it depends on the average closing price of Cabletron common stock for the ten trading days ending on and including the fifth trading day before the closing of the merger, and the fair market value of Cabletron series C preferred stock determined as of the fifth trading day before the closing date of the merger by an appraisal, both of which may fluctuate. Based on an average closing price of $17.89 per share of Cabletron common stock for the ten trading days ending on and including December 4, 2000 and an appraised value of $486.40 per share of Cabletron series C preferred stock as of December 4, 2000, and assuming the closing of the merger occurs on January 10, 2001 and a warrant to purchase 60,847 shares of Indus River series D preferred stock is not exercised before the merger: - each holder of Indus River series A preferred stock would receive 0.00271557 shares of Cabletron series C preferred stock and 0.21724568 shares of Cabletron common stock for each share of Indus River series A preferred stock held by that holder; - each holder of Indus River series B preferred stock would receive 0.00373338 shares of Cabletron series C preferred stock and 0.29867074 shares of Cabletron common stock for each share of Indus River series B preferred stock held by that holder; - each holder of Indus River series C preferred stock would receive 0.00448167 shares of Cabletron series C preferred stock and 0.35853378 shares of Cabletron common stock for each share of Indus River series C preferred stock held by that holder; - each holder of Indus River series D preferred stock issued on June 30, 1999 would receive .00514313 shares of Cabletron series C preferred stock and 0.41145079 shares of Cabletron common stock for each share of Indus River series D preferred stock held by that holder; - each holder of Indus River series D preferred stock issued on July 8, 1999 would receive 0.00513886 shares of Cabletron series C preferred stock and 0.41110886 shares of Cabletron common stock for each share of Indus River series D preferred stock held by that holder; and 3 - each holder of Indus River common stock would receive 0.00205897 shares of Cabletron series C preferred stock and 0.16471791 shares of Cabletron common stock for each share of Indus River common stock held by that holder. You will receive cash for any fractional share of Cabletron common stock or Cabletron series C preferred stock that you would be entitled to receive in the merger. The Cabletron series C preferred stock may be converted into Cabletron common stock at the option of the holder at any time after the earliest of: - a spin-off of Cabletron's subsidiary, Enterasys Networks, Inc., the subsidiary to which Cabletron intends to transfer the stock of Indus River after the merger, after the first anniversary of the date the Cabletron series C preferred stock is issued; - a transaction involving Enterasys after which Cabletron no longer controls Enterasys; and - the second anniversary of the date the Cabletron series C preferred stock is issued. If Cabletron establishes a record date for a spin-off of Enterasys before the first anniversary of the date the Cabletron series C preferred stock is issued, and that spin-off is to be completed before that anniversary, then the Cabletron series C preferred stock may be converted into Cabletron common stock at the option of the holder immediately before the spin-off. The Cabletron series C preferred stock may be redeemed at the option of the holder immediately before the first to occur of: - a spin-off of Enterasys after the first anniversary of the date the Cabletron series C preferred stock is issued and before the second anniversary of the issuance of the stock; and - a transaction involving Enterasys after which Cabletron no longer controls Enterasys before the second anniversary of the date the Cabletron series C preferred stock is issued. In a spin-off of Enterasys, Cabletron will pay the redemption price for each share of Cabletron series C preferred stock in shares of Enterasys stock. In a change of control of Enterasys, Cabletron will pay the redemption price for each share of Cabletron series C preferred stock in securities or assets of the surviving corporation immediately after the change of control of Enterasys. If Cabletron establishes a record date for a spin-off of Enterasys before the first anniversary of the date the Cabletron series C preferred stock is issued, holders of Cabletron series C preferred stock will not be able to redeem their shares of Cabletron series C preferred stock in the spin-off. However, they will be able to convert their shares into Cabletron common stock before the spin-off. If Cabletron begins a transaction resulting in a change of control of Enterasys before the first anniversary of the date the Cabletron series C preferred stock is issued, holders of Cabletron series C preferred stock will be able to redeem or convert their shares of Cabletron series C preferred stock in that transaction. If Cabletron conducts a spin-off of Enterasys after the first anniversary of the date the Cabletron series C preferred stock is issued, holders of Cabletron series C preferred stock will be able to redeem or convert their shares of Cabletron series C preferred stock in the spin-off. The terms of the Cabletron series C preferred stock will provide for a more favorable exchange ratio for redemption of the Cabletron series C preferred stock compared to the exchange ratio for conversion of the stock if the holders are able to choose between the two options. Cabletron is not obligated to conduct a spin-off of Enterasys or other disposition of Enterasys. If Cabletron does not do so, then holders of the Cabletron series C preferred stock will not be able to exercise the redemption right, and will not be able to exercise any conversion right until the second anniversary of the date 4 the Cabletron series C preferred stock is issued. A more detailed description of the Cabletron series C preferred stock is contained in the accompanying proxy statement/prospectus. The merger agreement provides that 10% of the shares of Cabletron common stock to be issued in the merger to the Indus River preferred stockholders and founders will be placed in an escrow account to secure the indemnification obligations of those Indus River stockholders under the merger agreement. All of the Cabletron series C preferred stock issued in the merger will be held in an escrow account for up to 30 months to facilitate any conversion or redemption of that stock which may occur within 24 months of the closing. If, after this 30-month period, there has been no redemption or conversion of the shares of Cabletron series C preferred stock, then those shares will be distributed to the stockholders who are entitled to receive them. Cabletron common stock is listed on the New York Stock Exchange under the trading symbol CS and on December 7, 2000, Cabletron common stock closed at $16.56 per share. The Cabletron series C preferred stock will not be listed on any securities exchange and there is no existing trading market for the Cabletron series C preferred stock. The shares of Cabletron series C preferred stock will not be transferable except under the laws of descent and distribution or to the partners of any stockholder which is an entity. Cabletron and Indus River plan to treat the merger as a tax-free reorganization for federal income tax purposes. After the merger, Cabletron plans to transfer all of the stock in Indus River to its subsidiary, Enterasys. Although Cabletron has announced its desire to establish its four operating subsidiaries, including Enterasys, as independent companies, Cabletron is not obligated to do so and continues to consider several possibilities for Enterasys, including retaining Enterasys as a subsidiary of Cabletron. Depending on if, and when, Cabletron conducts a spin-off or other disposition of Enterasys, the IRS may attempt to combine the merger with that other transaction, and take the position that the merger does not qualify as a tax-free organization. If the IRS were successful, you would recognize gain or loss for federal income tax purposes based on the difference between the fair market value of the Cabletron common stock and Cabletron series C preferred stock you received and the tax basis of the Indus River stock that you exchanged for the Cabletron common stock and the Cabletron series C preferred stock. A more detailed analysis of the material federal income tax consequences of the merger is discussed in the accompanying proxy statement/prospectus. Holders of Indus River stock who properly comply with statutory requirements will be entitled to an appraisal under Delaware law if the merger is completed. Completion of the merger requires the approval of the holders of a majority of the outstanding shares of Indus River common and preferred stock, voting together as a single class, and the holders of two-thirds of the outstanding shares of the Indus River convertible preferred stock, voting as a separate class. A number of Indus River stockholders have entered into a voting agreement with Cabletron, and have agreed to vote their shares of Indus River stock for adoption of the merger agreement. These stockholders have also granted to a Cabletron representative an irrevocable proxy and a power of attorney to vote its shares of Indus River stock for adoption of the merger agreement. On the record date, these stockholders in the aggregate owned and were entitled to vote: - 86.3% of the Indus River preferred stock and Indus River common stock, voting together as a single class; and - 95.5% of the Indus River preferred stock, voting as a separate class. Only stockholders who hold shares of Indus River stock at the close of business on December 4, 2000 will be entitled to vote at the special meeting. YOU SHOULD CONSIDER THE MATTERS DISCUSSED UNDER "RISK FACTORS" BEGINNING ON PAGE 13 OF THE ENCLOSED PROXY STATEMENT/PROSPECTUS BEFORE VOTING. PLEASE REVIEW CAREFULLY THE ENTIRE PROXY STATEMENT/PROSPECTUS. 5 AFTER CAREFUL CONSIDERATION, INDUS RIVER'S BOARD OF DIRECTORS HAS UNANIMOUSLY APPROVED THE MERGER AGREEMENT, AS IT HAS BEEN AMENDED, HAS UNANIMOUSLY DETERMINED THAT THE MERGER IS ADVISABLE AND IS FAIR TO YOU AND IN YOUR BEST INTERESTS AND UNANIMOUSLY RECOMMENDS THAT YOU VOTE FOR THE ADOPTION OF THE MERGER AGREEMENT.

Annexes: Annex A Agreement and Plan of Merger Annex B Section 262 of the Delaware General Corporation Law Annex C Form of Escrow Agreement Annex D Form of Stockholder Agreement for Founders Annex E Form of Stockholder Agreement for Preferred Stockholders Annex F Preliminary Appraisal of Adams, Harkness & Hill, Inc. dated December 5, 2000 ii 11 QUESTIONS AND ANSWERS ABOUT THE MERGER AND THE SPECIAL MEETING Q: WHY IS INDUS RIVER MERGING WITH CABLETRON? A: Indus River will join and become part of Cabletron, one of the world's leading developers, manufacturers and marketers of networking systems and technology, and Indus River stockholders will become Cabletron stockholders. Indus River will be joining Cabletron's Enterasys division, a leading provider of global business communication solutions to enterprise customers. By joining Enterasys, Indus River gains access to Enterasys' large installed base of enterprise customers and generally gains access to Enterasys' large distribution channels. Q: WHAT WILL I RECEIVE IN THE MERGER? A: Cabletron will issue an aggregate of 4,000,000 shares of Cabletron common stock and 50,000 shares of Cabletron series C preferred stock in exchange for all of the shares of Indus River preferred stock, Indus River common stock, and all options and warrants to purchase Indus River stock. Cabletron will also reserve for issuance approximately 100,000 additional shares of Cabletron common stock and 1,100 additional shares of Cabletron series C preferred stock to be issued to holders of additional options granted in exchange for the forfeiting of acceleration rights and some options granted to some employees hired by Indus River after August 18, 2000. If the merger is completed, you will receive a specified number of shares of Cabletron common stock and Cabletron series C preferred stock for each share of Indus River common stock and Indus River preferred stock that you own, and cash for any fractional share of Cabletron common stock and any fractional share of Cabletron series C preferred stock you would be entitled to receive in the merger. Holders of Indus River preferred stock are entitled to be paid a liquidation preference payment as part of the merger. Because the dollar amount of the liquidation preference will be determined as of the closing date and because the number of shares of Cabletron series C preferred stock and Cabletron common stock constituting the liquidation preference payment will be determined based on a 10 trading day average closing price of Cabletron's common stock and an appraised value of the Cabletron series C preferred stock, the exact exchange ratios for the number of shares of Cabletron common stock and Cabletron series C preferred stock to be issued in the merger will not be known until the fifth trading day before the closing date. Based on an average closing price of $17.89 per share of Cabletron common stock for the ten trading days ending on and including December 4, 2000 and an appraised value of $496.80 per share of Cabletron series C preferred stock as of December 4, 2000, and assuming that the closing of the merger occurs on January 10, 2001 and a warrant to purchase 60,847 shares of Indus River series D preferred stock is not exercised before the merger: - each holder of Indus River series A preferred stock would receive 0.00271557 shares of Cabletron series C preferred stock and 0.21724568 shares of Cabletron common stock for each share of Indus River series A preferred stock held by that holder; - each holder of Indus River series B preferred stock would receive 0.00373338 shares of Cabletron series C preferred stock and 0.29867074 shares of Cabletron common stock for each share of Indus River series B preferred stock held by that holder; - each holder of Indus River series C preferred stock would receive 0.00448167 shares of Cabletron series C preferred stock and 0.35853378 shares of Cabletron common stock for each share of Indus River series C preferred stock held by that holder; - each holder of Indus River series D preferred stock issued on June 30, 1999 would receive 0.00514313 shares of Cabletron series C preferred stock and 0.41145079 shares of Cabletron common stock for each share of Indus River series D preferred stock held by that holder; 12 - each holder of Indus River series D preferred stock issued on July 8, 1999 would receive 0.00513886 shares of Cabletron series C preferred stock and 0.41110886 shares of Cabletron common stock for each share of Indus River series D preferred stock held by that holder; and - each holder of Indus River common stock would receive 0.00205897 shares of Cabletron series C preferred stock and 0.16471791 shares of Cabletron common stock for each share of Indus River common stock held by that holder. The Cabletron series C preferred stock may be converted into Cabletron common stock at the option of the holder at any time after the earliest of: - a spin-off of Cabletron's subsidiary, Enterasys Networks, Inc., the subsidiary to which Cabletron intends to transfer the stock of Indus River after the merger, after the first anniversary of the date the Cabletron series C preferred stock is issued; - a transaction involving Enterasys after which Cabletron no longer controls Enterasys at any time; and - the second anniversary of the date the Cabletron series C preferred stock is issued. If Cabletron establishes a record date for a spin-off of Enterasys before the first anniversary of the date the Cabletron series C preferred stock is issued, and that spin-off is to be completed before that anniversary, then the Cabletron series C preferred stock may be converted into Cabletron common stock at the option of the holder immediately before the spin-off. The Cabletron series C preferred stock may be redeemed at the option of the holder immediately before the first to occur of: - a spin-off of Enterasys after the first anniversary of the date the Cabletron series C preferred stock is issued and before the second anniversary of the issuance of the stock; and - a transaction involving Enterasys after which Cabletron no longer controls Enterasys before the second anniversary of the date the Cabletron series C preferred stock is issued. In a spin-off of Enterasys, Cabletron will pay the redemption price for each share of Cabletron series C preferred stock in shares of Enterasys stock. In a change of control of Enterasys, Cabletron will pay the redemption price for each share of Cabletron series C preferred stock in securities or assets of the surviving corporation immediately after the change of control of Enterasys. If Cabletron establishes a record date for a spin-off of Enterasys before the first anniversary of the date the Cabletron series C preferred stock is issued, holders of Cabletron series C preferred stock will not be able to redeem their shares of Cabletron series C preferred stock in the spin-off. However, they will be able to convert their shares into Cabletron common stock before the spin-off. If Cabletron begins a transaction resulting in a change of control of Enterasys before the first anniversary of the date the Cabletron series C preferred stock is issued, holders of Cabletron series C preferred stock will be able to redeem or convert their shares of Cabletron series C preferred stock in that transaction. If Cabletron conducts a spin-off of Enterasys after the first anniversary of the date the Cabletron series C preferred stock is issued, holders of Cabletron series C preferred stock will be able to redeem or convert their shares of Cabletron series C preferred stock in the spin-off. The terms of the Cabletron series C preferred stock will provide a more favorable exchange ratio for redemption of the Cabletron series C preferred stock compared to the exchange ratio for conversion of the stock if the holders are able to choose between the two options. Cabletron is not obligated to conduct a spin-off of Enterasys or other disposition of Enterasys. If Cabletron does not do so, then holders of the Cabletron series C preferred stock will not be able to exercise the redemption right at all, and will not be able to exercise any conversion right until the second anniversary of the date the Cabletron series C preferred stock is issued. There is a description of the Cabletron series C preferred stock on pages 59 to 66 of this proxy statement/prospectus. 2 13 The merger agreement provides that 10% of the shares of Cabletron common stock to be issued in the merger to the Indus River preferred stockholders and founders will be placed in an escrow account to secure the indemnification obligations of those Indus River stockholders under the merger agreement. All of the shares of Cabletron series C preferred stock issued in the merger will be deposited in an escrow account for a period of up to 30 months to facilitate any conversion or redemption of that stock. Q: WHAT IS THE ESCROW FUND AND HOW DOES IT WORK? A: If the merger is completed, Cabletron will deposit into an escrow account 10% of the Cabletron common stock to be issued to the preferred stockholders and founders of Indus River. The escrowed shares will be available to compensate Cabletron if it is entitled to indemnification under the merger agreement. The escrow account will be the sole and exclusive source available to compensate Cabletron for damages due to a breach under the merger agreement, other than for any claim of fraud, intentional misrepresentation or other willful conduct. Any escrowed shares not used to indemnify Cabletron and which are not the subject of an unresolved claim for indemnification by Cabletron will be distributed to the Indus River stockholders entitled to receive them after the first anniversary of the merger. If the merger is completed, Cabletron will deposit into a separate escrow account all of the Cabletron series C preferred stock to be issued to all Indus River stockholders. The escrowed shares of Cabletron series C preferred stock will not be used to secure the indemnification obligations of Indus River stockholders, but rather will be held in escrow only to facilitate any conversion or redemption of the shares of Cabletron series C preferred stock occurring within 24 months of the closing. The shares of Cabletron series C preferred stock will remain in the escrow account for up to 30 months. If, after this 30-month period, there has been no redemption or conversion of the shares of Cabletron series C preferred stock, then those shares will be distributed by the escrow agent to the stockholders on whose behalf the shares are being held. Q: WHY IS THE INDUS RIVER BOARD OF DIRECTORS RECOMMENDING THAT I VOTE FOR ADOPTION OF THE MERGER AGREEMENT? A: After considering the support for the merger from its independent directors and the other reasons described on pages 27 to 28 of this proxy statement/prospectus, your board of directors unanimously believes that the terms of the merger agreement are advisable and fair to, and in the best interests of, Indus River and its stockholders. Q: WHAT IS THE VOTE REQUIRED TO ADOPT THE MERGER AGREEMENT? A: The affirmative vote of the holders of: - a majority of the outstanding shares of Indus River common stock and Indus River preferred stock, voting together as a single class; and - two-thirds of the outstanding shares of Indus River preferred stock, voting as a separate class, is required to adopt the merger agreement. You will be able to vote your shares of Indus River common stock and Indus River preferred stock at a special meeting of Indus River stockholders to be held on January 10, 2001 at 10:00 a.m., local time, at the offices of McDermott, Will & Emery, 28 State Street, Boston, Massachusetts 02109. Indus River stockholders holding: - 86.3% of the outstanding shares of Indus River preferred stock and Indus River common stock, voting together as a single class; and - 95.5% of the outstanding shares of Indus River preferred stock, voting as a separate class, have executed stockholder agreements agreeing to vote their shares of Indus River stock for adoption of the merger agreement. These stockholders have also granted an irrevocable proxy and a power of attorney to Cabletron representatives to vote their shares of Indus River stock for adoption of the merger agreement. Thus, the required vote to adopt the merger agreement has been obtained. There is a description of these stockholder agreements on page 22 of this proxy statement/prospectus. 3 14 Q: WHAT IF THE MERGER IS NOT COMPLETED? A: It is possible the merger will not be completed. That might happen if, for example, any of the closing conditions specified in the merger agreement do not occur. Should that occur, Cabletron, Indus River or any third party is not under any obligation to make or consider any alternative proposal to purchase your Indus River stock. The closing conditions specified in the merger agreement are described in pages 45 to 46 of this proxy statement/prospectus. Q: WHAT ELSE WILL HAPPEN AT THE MEETING? A: Although we expect no other matters to come before the special meeting, the stockholders of Indus River may transact any other business that may properly come before the meeting. Q: WHAT DO I NEED TO DO NOW? A: After carefully reading and considering the information contained in this proxy statement/prospectus, PLEASE COMPLETE AND SIGN YOUR PROXY CARD AND RETURN IT IN THE ENCLOSED RETURN ENVELOPE AS SOON AS POSSIBLE SO THAT YOUR SHARES MAY BE REPRESENTED AT THE SPECIAL MEETING. If you sign and send in your proxy card and do not indicate how you want to vote, we will count your proxy as a vote for adoption of the merger agreement. IF YOU ABSTAIN FROM VOTING OR DO NOT VOTE ON THE PROPOSAL, YOUR ABSTENTION OR FAILURE TO VOTE WILL HAVE THE SAME EFFECT AS A VOTE AGAINST ADOPTION OF THE MERGER AGREEMENT. The special meeting will take place on January 10, 2001. You may attend the special meeting and vote your shares in person, rather than signing and mailing your proxy card. Q: WHO MAY VOTE AT THE SPECIAL MEETING? A: All stockholders of record as of the close of business on December 4, 2000 may vote. You are entitled to one vote for each share of Indus River common stock that you own on the record date, and one vote for each share of Indus River preferred stock that you own on the record date. Q: MAY I CHANGE MY VOTE AFTER I HAVE MAILED MY SIGNED PROXY CARD? A: Yes. You may change your vote in one of three ways before your proxy is voted at the special meeting. First, you may send a written notice stating that you would like to revoke your proxy. Second, you may complete and submit a new proxy card. If you choose either of these two methods, you must submit your notice of revocation or your new proxy card to the secretary of Indus River at the address given in the answer to the last question below. Third, you may attend the special meeting and vote in person. Q: SHOULD I SEND IN MY STOCK CERTIFICATES NOW? A: No. After the merger has been completed, you will receive written instructions for exchanging your stock certificates. PLEASE DO NOT SEND IN YOUR STOCK CERTIFICATES WITH YOUR PROXY CARD.

For a more complete understanding of the merger, you should carefully read this entire proxy statement/prospectus and the other documents to which we refer you. You should read the documents attached to this proxy statement/prospectus, including the merger agreement and the amendment to the merger agreement which are attached as annex A, your appraisal rights under Delaware law, which are attached as annex B, the form of escrow agreement which is attached as annex C, the form of stockholder agreement for Indus River founders, which is attached as annex D, the form of stockholder agreement for Indus River preferred stockholders, which is attached as annex E, and the preliminary appraisal of Adams, Harkness & Hill, Inc. dated December 5, 2000 of the Cabletron series C preferred stock, which is attached as annex F. GENERAL WHAT YOU WILL RECEIVE IN THE MERGER Cabletron will issue an aggregate of 4,000,000 shares of Cabletron common stock and 50,000 shares of Cabletron series C preferred stock in exchange for all of the shares of Indus River preferred stock, Indus River common stock, and all options and warrants to purchase Indus River stock. Cabletron will also reserve for issuance approximately 100,000 additional shares of Cabletron common stock and 1,100 additional shares of Cabletron series C preferred stock to be issued to holders of additional options granted in exchange for the forfeiting of acceleration rights and some options granted to some employees hired by Indus River after August 18, 2000. Because each holder of Indus River preferred stock is entitled to a liquidation preference payment as part of the merger, and because the market price of Cabletron common stock fluctuates and the value of the Cabletron series C preferred stock also varies, the exact exchange rate for Indus River preferred stock and Indus river common stock will not be known until five trading days before the closing date of the merger. Based on an average closing price of $17.89 per share of Cabletron common stock for the ten trading days ending on and including December 4, 2000 and an appraised value of $486.40 per share of Cabletron series C preferred stock as of December 4, 2000, and assuming that the closing of the merger occurs on January 10, 2001 and a warrant to purchase 60,847 shares of Indus River series D preferred stock is not exercised before the merger: - each holder of Indus River series A preferred stock would receive 0.00271557 shares of Cabletron series C preferred stock and 0.21724568 shares of Cabletron common stock for each share of Indus River series A preferred stock held by that holder; - each holder of Indus River series B preferred stock would receive 0.00373338 shares of Cabletron series C preferred stock and 0.29867074 shares of Cabletron common stock for each share of Indus River series B preferred stock held by that holder; - each holder of Indus River series C preferred stock would receive 0.00448167 shares of Cabletron series C preferred stock and 0.35853378 shares of Cabletron common stock for each share of Indus River series C preferred stock held by that holder; - each holder of Indus River series D preferred stock issued on June 30, 1999 would receive 0.00514313 shares of Cabletron series C preferred stock and 0.41145079 shares of Cabletron common stock for each share of Indus River series D preferred stock held by that holder; - each holder of Indus River series D preferred stock issued on July 8, 1999 would receive 0.00513886 shares of Cabletron series C preferred stock and 0.41110886 shares of Cabletron common stock for each share of Indus River series D preferred stock held by that holder; and 6 17 - each holder of Indus River common stock would receive 0.00205897 shares of Cabletron series C preferred stock and 0.16471791 shares of Cabletron common stock for each share of Indus River common stock held by that holder. You will receive cash for any fractional share of Cabletron common stock or Cabletron series C preferred stock that you would be entitled to receive in the merger. The Cabletron series C preferred stock may be converted into Cabletron common stock at the option of the holder at any time after the earliest of: - a spin-off of Cabletron's subsidiary, Enterasys Networks, Inc., the subsidiary to which Cabletron intends to transfer the stock of Indus River after the merger, after the first anniversary of the date the Cabletron series C preferred stock is issued; - a transaction involving Enterasys after which Cabletron no longer controls Enterasys at any time; and - the second anniversary of the date the Cabletron series C preferred stock is issued. If Cabletron establishes a record date for a spin-off of Enterasys before the first anniversary of the date the Cabletron series C preferred stock is issued, and that spin-off is to be completed before that anniversary, then the Cabletron series C preferred stock may be converted into Cabletron common stock at the option of the holder immediately before the spin-off. The Cabletron series C preferred stock may be redeemed at the option of the holder immediately before to the first to occur of: - a spin-off of Enterasys after the first anniversary of the date the Cabletron series C preferred stock is issued and before the second anniversary of the issuance of the stock; and - a transaction involving Enterasys after which Cabletron no longer controls Enterasys before the second anniversary of the date the Cabletron series C preferred stock is issued. In a spin-off of Enterasys, Cabletron will pay the redemption price for each share of Cabletron series C preferred stock in shares of Enterasys stock. In a change of control of Enterasys, Cabletron will pay the redemption price for each share of Cabletron series C preferred stock in securities or assets of the surviving corporation immediately after the change of control of Enterasys. If Cabletron establishes a record date for a spin-off of Enterasys before the first anniversary of the date the Cabletron series C preferred stock is issued, holders of Cabletron series C preferred stock will not be able to redeem their shares of Cabletron series C preferred stock in the spin-off. However, they will be able to convert their shares into Cabletron common stock before the spin-off. If Cabletron begins a transaction resulting in a change of control of Enterasys before the first anniversary of the date the Cabletron series C preferred stock is issued, holders of Cabletron series C preferred stock will be able to redeem or convert their shares of Cabletron series C preferred stock in that transaction. If Cabletron conducts a spin-off of Enterasys after the first anniversary of the date the Cabletron series C preferred stock is issued, holders of Cabletron series C preferred stock will be able to redeem or convert their shares of Cabletron series C preferred stock in the spin-off. The terms of the Cabletron series C preferred stock will provide for a more favorable exchange ratio for redemption of the Cabletron series C preferred stock compared to the exchange ratio for conversion of the stock if the holders are able to choose between the two options. Cabletron is not obligated to conduct a spin-off of Enterasys or other disposition of Enterasys. If Cabletron does not do so, then holders of the Cabletron series C preferred stock will not be able to exercise the redemption right, and will not be able to exercise any conversion right until the second anniversary of the date the Cabletron series C preferred stock is issued. The merger agreement provides that 10% of the shares of Cabletron common stock to be issued in the merger to the Indus River preferred stockholders and founders will be placed in an escrow account that may 7 18 be used to compensate Cabletron if it is entitled to indemnification under the merger agreement. The escrow account will be the sole and exclusive source available to compensate Cabletron for damages due to a breach under the merger agreement, other than for any claim of fraud, intentional misrepresentation or other willful conduct. Any escrowed shares not used to indemnify Cabletron and which are not the subject of an unresolved claim for indemnification by Cabletron will be distributed to each Indus River stockholder on whose behalf the escrowed shares are being held after the first anniversary of the merger. All of the shares of Cabletron series C preferred stock will be placed in a separate escrow account with an escrow agent. The Cabletron series C preferred stock will not be used to secure the indemnification obligations of Indus River stockholders, but rather will be held in escrow only to facilitate any conversion or redemption of the Cabletron series C preferred stock occurring within 24 months of the closing. The shares of Cabletron series C preferred stock will remain in the escrow account for up to 30 months. If, after this 30-month period, there has been no conversion or redemption of the shares of Cabletron series C preferred stock, then those shares will be distributed to the stockholders on whose behalf the shares are being held. SIGNIFICANT UNITED STATES FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER Cabletron and Indus River plan to treat the merger as a tax-free reorganization for federal income tax purposes. After the merger, Cabletron plans to transfer all of the stock in Indus River to its subsidiary, Enterasys. Although Cabletron has announced its desire to establish its four operating subsidiaries, including Enterasys, as independent companies, Cabletron is not obligated to do so and continues to consider several possibilities for Enterasys, including retaining Enterasys as a subsidiary of Cabletron. Depending on if, and when, Cabletron conducts a spin-off or other disposition of Enterasys, the Internal Revenue Service may attempt to combine the merger with that other transaction, and take the position that the merger does not qualify as a tax-free reorganization. If the IRS were successful, you would recognize gain or loss for federal income tax purposes based on the difference between the fair market value of the Cabletron common stock and Cabletron series C preferred stock you received and the tax basis of the Indus River stock that you exchanged for the Cabletron common stock and the Cabletron series C preferred stock. RECOMMENDATION OF THE INDUS RIVER BOARD OF DIRECTORS The Indus River board of directors believes that the terms of the merger and the merger agreement are advisable and fair to, and in the best interests of, Indus River and its stockholders and unanimously recommends that stockholders vote for adoption of the merger agreement. APPRAISALS OF CABLETRON SERIES C PREFERRED STOCK BY ADAMS, HARKNESS & HILL, INC. There is no established trading market for the Cabletron series C preferred stock. Indus River has retained Adams, Harkness & Hill, Inc. to deliver an appraisal of the fair market value of the shares of Cabletron series C preferred stock to be paid as the liquidation preference payment due to Indus River preferred stockholders in the merger. At the request of Indus River, Adams, Harkness & Hill delivered a preliminary appraisal on December 5, 2000 that, as of December 4, 2000, the aggregate fair market value of the Cabletron series C preferred stock to be received by the Indus River stockholders in the merger was approximately $24.32 million. It is possible that the valuation determined in the final appraisal could be materially different from that determined in the preliminary appraisal. Adams, Harkness & Hill's appraisal addresses only the fair market value of the Cabletron series C preferred stock to be received under the merger agreement and does not address any other aspect of the merger or constitute a recommendation to any holder of Indus River stock about how to vote at the Indus River stockholder meeting. INTERESTS OF INDUS RIVER DIRECTORS, MANAGEMENT AND EMPLOYEES IN THE MERGER A number of directors, officers and employees of Indus River have interests in the merger as directors, officers or employees that are different from those of a stockholder generally. If we complete the merger, indemnification arrangements for current directors, officers and employees of Indus River will be continued 8 19 and it is anticipated that some employees of Indus River will be retained as employees of Cabletron. It is a condition of the merger that some executives and employees, with stock options, enter into amendments to their stock option agreements to modify the accelerated vesting provisions for those options in exchange for the grant of additional stock options. Two executive officers of Indus River will also receive options to purchase 200,000 shares of stock of Cabletron's subsidiary, Enterasys. APPRAISAL RIGHTS If you do not wish to accept Cabletron common stock and Cabletron series C preferred stock in the merger, you have the right under Delaware law to have the fair value of your shares determined by the Delaware chancery court. This right to appraisal is subject to a number of restrictions and technical requirements. Generally, to exercise your appraisal rights you must: - send a written demand to Indus River for appraisal in compliance with Delaware law before the vote on the merger; - not vote in favor of the merger; and - continuously hold your Indus River stock, from the date you make the demand for appraisal through the closing of the merger. Merely voting against the merger will not protect your rights to an appraisal. If you fail to follow all the steps required by Delaware law you will lose your rights to appraisal.

We are unable to provide information about the market prices of the Cabletron series C preferred stock and the Indus River stock, and the equivalent per share market prices of Cabletron common stock have been omitted, because there is no established trading market for shares of Indus River stock. Cabletron has never paid dividends on its common stock and anticipates it will continue to reinvest earnings to finance future growth. Indus River has never paid dividends on its common stock. THE SPECIAL MEETING The special meeting of Indus River stockholders will be held at the offices of McDermott, Will & Emery, 28 State Street, 34th Floor, Boston, Massachusetts 02109, at 10:00 a.m. local time on January 10, 2001.

RECORD DATE; VOTING POWER Indus River stockholders are entitled to notice of, and to vote at, the special meeting if they owned shares as of the close of business on December 4, 2000 the record date. VOTE REQUIRED The affirmative vote of holders of: - a majority of the outstanding shares of the Indus River common stock and preferred stock, voting together as a single class; and - two-thirds of the outstanding shares of the Indus River preferred stock, voting together as a single class, is required to adopt the merger agreement. WE CANNOT COMPLETE THE MERGER UNLESS THE MERGER PROPOSAL IS ADOPTED BY THE REQUIRED VOTE. 10 21 STOCKHOLDER AGREEMENTS A number of Indus River stockholders have entered into stockholder agreements with Cabletron and have agreed to vote their shares of Indus River stock for adoption of the merger agreement. These stockholders have also granted an irrevocable proxy and a power of attorney to Cabletron representatives to vote that stockholder's shares of Indus River stock for adoption of the merger agreement. On the record date, these stockholders in the aggregate owned and agreed to vote 86.3% of the Indus River preferred stock and Indus River common stock, voting together as a single class, and 95.5% of the preferred stock, voting together as a single class. GOVERNMENT FILINGS Cabletron and Indus River do not believe that any governmental filings are required for the merger, except for the filing of the registration statement with the Securities and Exchange Commission of which this proxy statement/prospectus is a part. 11 22 SELECTED HISTORICAL FINANCIAL DATA -- CABLETRON HISTORICAL

THE INFORMATION IN THIS SECTION SHOULD BE READ WITH CABLETRON'S HISTORICAL FINANCIAL STATEMENTS AND ACCOMPANYING NOTES. 12 23 RISK FACTORS Indus River stockholders should consider carefully the matters described below in determining whether to adopt the merger agreement. RISK FACTORS RELATING TO THE MERGER - DECREASES IN THE PRICE OR VALUE OF CABLETRON COMMON STOCK AND CABLETRON SERIES C PREFERRED STOCK WILL NOT ENTITLE INDUS RIVER STOCKHOLDERS OR OPTIONHOLDERS TO RECEIVE ADDITIONAL CABLETRON SHARES IN THE MERGER. Cabletron will issue a fixed number of shares of Cabletron common stock and Cabletron series C preferred stock in the merger transaction, including to holders of options and warrants to purchase Indus River stock. Changes in the price of Cabletron common stock or in the value of Cabletron series C preferred stock will not result in an adjustment in the total shares of Cabletron common stock and Cabletron series C preferred stock to be issued by Cabletron. If the price or value of Cabletron common stock or Cabletron series C preferred stock declines, then the value to Indus River stockholders of the merger transaction will also decline. The price of Cabletron common stock and the value of Cabletron series C preferred stock may vary because of changes in the business, operations or prospects of Cabletron, the timing of the completion of the merger, the prospects of post-merger operations and general market and economic conditions. Because the date that the merger is completed may be later than the date of the special meeting, the price of Cabletron common stock and the value of Cabletron series C preferred stock on the date of the special meeting may not be indicative of its price on the date the merger is completed. We urge Indus River stockholders to obtain current market quotations for Cabletron common stock. - THE SHARES OF CABLETRON COMMON STOCK THAT WILL BE ISSUED IN THE MERGER TO THE INDUS RIVER PREFERRED STOCKHOLDERS AND FOUNDERS AND PLACED IN ESCROW TO SECURE CABLETRON'S INDEMNIFICATION CLAIMS UNDER THE MERGER AGREEMENT MAY NEVER BE DISTRIBUTED TO THE INDUS RIVER PREFERRED STOCKHOLDERS AND FOUNDERS. The merger agreement provides that the shares of Cabletron common stock placed in escrow will be available to indemnify Cabletron, the surviving corporation and other specified persons after the merger for breaches by Indus River of the merger agreement. If Indus River breaches the merger agreement, Cabletron would be entitled to be paid from the escrow fund the amount necessary to satisfy its damages. Indus River founders and preferred stockholders may not receive any of the shares in the escrow account since those shares might be used to indemnify Cabletron. - DEPENDING ON IF, AND WHEN, CABLETRON CONDUCTS A SPIN-OFF OR OTHER DISPOSITION OF ENTERASYS, THE IRS MAY TAKE THE POSITION THAT THE MERGER IS TAXABLE. Cabletron and Indus River plan to treat the merger as a tax-free reorganization for federal income tax purposes. The federal income tax treatment of the merger depends in part on whether, for federal income tax purposes, the merger would be combined with a spin-off or other disposition of Enterasys by Cabletron, the company to which Cabletron plans to transfer the Indus River stock after the merger. Cabletron has announced its desire to establish its four operating subsidiaries, including Enterasys, as independent companies. Because Cabletron is not obligated to carry out a spin-off or any other disposition of Enterasys and continues to consider several possibilities for Enterasys, including retaining Enterasys as a subsidiary of Cabletron, Cabletron and Indus River plan to treat the merger as a tax-free reorganization. If Cabletron carries out its announced intention to spin off or dispose of Enterasys, and if the IRS were to successfully assert that the spin-off or disposition should be combined with this merger, then this merger would constitute a taxable purchase of stock. You would recognize gain or loss for federal income tax purposes based on the difference between the fair market value of the Cabletron common stock and Cabletron series C preferred stock you received and the tax basis of the Indus River stock that you exchanged for the Cabletron common stock and the Cabletron series C preferred stock. RISK FACTORS RELATING TO THE CABLETRON SERIES C PREFERRED STOCK - BECAUSE THE CABLETRON SERIES C PREFERRED STOCK WILL NOT BE REGISTERED FOR RESALE AND WILL NOT HAVE A LIQUID MARKET, THE HOLDERS OF CABLETRON SERIES C PREFERRED STOCK WILL BE LIMITED IN THEIR ABILITY TO 13 24 TRANSFER OR SELL THEIR SHARES. The Cabletron series C preferred stock will not be registered for resale under the Securities Act and may not be transferred except under the laws of descent and distribution or to the partners or equity holders of any stockholder which is an entity. There is no existing market for the Cabletron series C preferred stock and a liquid market may not develop for the Cabletron series C preferred stock. The holders of Cabletron series C preferred stock may be unable to sell their Cabletron series C preferred stock, and the price at which holders of the Cabletron series C preferred stock may be able to sell their Cabletron series C preferred stock, if at all, is uncertain. Cabletron does not intend to apply for listing of its series C preferred stock on any securities exchange. - THE HOLDERS OF CABLETRON SERIES C PREFERRED STOCK MAY NEVER BE ABLE TO REDEEM THEIR SHARES OF CABLETRON SERIES C PREFERRED STOCK. The terms of the Cabletron series C preferred stock provide that those shares may be redeemed if Cabletron conducts a spin-off of its subsidiary, Enterasys, after the first anniversary of the issuance of the shares and before the second anniversary of the issuance of the shares. These shares may also be redeemed if there is a transaction involving Enterasys after which Cabletron no longer controls Enterasys before the second anniversary of the issuance of the shares. It is possible that Cabletron will not conduct a spin-off of Enterasys within this time frame. Similarly, it is possible that there will not be a change of control of Enterasys within this time frame. The holders of Cabletron series C preferred stock may not able to redeem their shares of Cabletron series C preferred stock. - THE HOLDERS OF CABLETRON SERIES C PREFERRED STOCK MAY NOT BE ABLE TO CONVERT THEIR SHARES FOR A PERIOD OF TWO YEARS. The terms of the Cabletron series C preferred stock provide that those shares may be converted by the holders into shares of Cabletron common stock after the earlier to occur of a spin-off of Enterasys, a transaction involving Enterasys after which Cabletron no longer controls Enterasys, and the second anniversary of the issuance of the Cabletron series C preferred stock. If Cabletron conducts a spin-off of Enterasys within one year of the issuance of the Cabletron series C preferred stock, the shares of Cabletron series C preferred stock may be converted immediately before the spin-off. It is possible that Cabletron will not conduct an Enterasys spin-off before the second anniversary of the issuance of the Cabletron series C preferred stock. Similarly, it is possible that there will not be a change of control of Enterasys within this time frame. The holders of Cabletron series C preferred stock may not be able to convert their shares of Cabletron series C preferred stock until after the second anniversary of the issuance of the shares of Cabletron series C preferred stock. RISK FACTORS RELATING TO CABLETRON Cabletron's business is subject to numerous risks and uncertainties, including those described below. References to Cabletron are to Cabletron and its subsidiaries, through which Cabletron conducts its operations. - IF CABLETRON IS NOT ABLE TO COMPLETE ITS PLANNED TRANSFORMATION ITS PROFITABILITY COULD DECLINE BECAUSE CABLETRON WILL HAVE INCURRED SIGNIFICANT COSTS AND EXPENSES TO ATTEMPT THE TRANSFORMATION. Cabletron has transformed its business by creating four operating subsidiaries and transferring a portion of its operating assets and related liabilities to these four subsidiaries. Cabletron plans to conduct an initial public offering of some or all of the operating subsidiaries followed by a distribution of the remaining shares of the operating subsidiaries to Cabletron's stockholders. Cabletron may also consider selling one or more of its operating subsidiaries. If Cabletron does not complete the transformation as planned, Cabletron's profitability could decline. Cabletron will have devoted significant time and resources to complete the transformation. Cabletron will have already incurred increased expenses for the build-up of management and administrative capacity of each operating subsidiary. Cabletron is not obligated to complete any of these strategic transactions, and it is uncertain when or whether any of these transactions will happen. - EVEN IF CABLETRON SUCCESSFULLY COMPLETES ITS PLANNED TRANSFORMATION, ITS PROFITABILITY COULD DECLINE IF CABLETRON CANNOT OFFSET THE COSTS AND EXPENSES OF THE TRANSFORMATION WITH INCREASED REVENUES, PROFIT MARGINS OR SALES THAT THE TRANSFORMATION IS INTENDED TO PRODUCE. As part of its transformation, Cabletron has announced plans to discontinue several product lines to allow the new subsidiaries to focus on their core technologies. The discontinuance of these products may cause Cabletron's overall 14 25 revenue or profitability to decrease in the future if it is unable to increase sales of other products or if it is unable to increase profit margins. The cost of the transformation, such as the buildup of management and administrative capacity at each subsidiary, could also impair Cabletron's profitability. - NEGATIVE EVENTS IN THE PUBLIC MARKET FOR TECHNOLOGY STOCKS MAY PREVENT CABLETRON FROM COMPLETING ITS PLANNED TRANSFORMATION AND THIS MAY CAUSE CABLETRON'S PROFITABILITY TO DECLINE BECAUSE CABLETRON WILL HAVE INCURRED SIGNIFICANT COSTS AND EXPENSES TO ATTEMPT THE TRANSFORMATION. The public market for technology stocks has recently experienced a significant downturn, with many stocks suffering price declines of 50 percent or more. Trading in these stocks has become extremely volatile. If current market conditions persist, Cabletron may be unable or unwilling to complete initial public offerings or private sales of any of its operating subsidiaries. Cabletron's profitability could decline because it will have already incurred significant costs and expenses to complete the transformation, including the public offerings or sales of the operating subsidiaries. - CABLETRON MAY NOT OBTAIN APPROVAL OF ALL ASPECTS OF ITS PLANNED TRANSFORMATION, OR MAY NOT CARRY OUT ITS INTENT EVEN IF THE APPROVALS ARE OBTAINED AND THIS MAY CAUSE CABLETRON'S PROFITABILITY TO DECLINE BECAUSE CABLETRON WILL HAVE INCURRED SIGNIFICANT COSTS AND EXPENSES TO ATTEMPT THE TRANSFORMATION. Any distribution of shares of a subsidiary to Cabletron's stockholders may depend on receipt from the Internal Revenue Service of a ruling that the distribution would be tax-free to Cabletron's stockholders, that the transaction would qualify as a tax-free reorganization, or other regulatory approvals. Also, a public offering of any shares of a Cabletron subsidiary will depend on factors such as the market conditions for public offerings, the operating performance of that subsidiary, and the prospects of the markets for that subsidiary's goods or services. Any of the strategic transactions related to Cabletron's transformation would be implemented only if Cabletron's board of directors continues to believe that the transaction is in the best interests of Cabletron, its stockholders, and its subsidiaries. Cabletron's profitability could decline because it will have already incurred significant costs and expenses to complete the transformation, including the public offerings or sales of the operating subsidiaries. - CABLETRON FACES SIGNIFICANT COMPETITIVE PRESSURES IN THE DATA NETWORKING INDUSTRY THAT MIGHT CAUSE CABLETRON TO LOSE MARKET SHARE, SUFFER DECREASED REVENUES OR EXPERIENCE FLUCTUATIONS IN OPERATING RESULTS. The data networking industry is subject to intense and increasing levels of competition and consolidation. Cabletron expects substantial increases in future competition from its current competitors, and from new competitors that enter Cabletron's existing or future markets, including, by acquiring data networking companies. Increased competition could result in lower sales, reduced margins and loss of market share. Any of these factors could increase fluctuations in operating results. If Cabletron fails to successfully develop and market new products, enhance existing products or respond adequately to technological changes, new standards or product announcements, Cabletron may lose market share, and may suffer decreased revenues because of the loss of market share. Cabletron's primary competitors are Cisco, Lucent, Nortel, 3Com, Extreme Networks, Foundry Networks and Juniper Networks. Several large telecommunications equipment companies, including Nokia Corp., Alcatel, Ericsson and Siemens have begun to compete in the data networking industry and have recently made investments in or acquired several smaller data networking companies. - IF CABLETRON IS UNABLE TO DEVELOP AND MAINTAIN BRAND RECOGNITION IT MAY HAVE DIFFICULTY ATTRACTING CUSTOMERS. As the data networking industry has grown and matured, customers purchasing decisions have been increasingly influenced by brand recognition. If Cabletron is unable to develop and maintain competitive brand recognition, Cabletron's market share will likely decrease. - IF CABLETRON IS UNABLE TO ACQUIRE DATA NETWORKING COMPANIES OR INVEST IN THEM IT MAY NOT BE ABLE TO INTRODUCE NEW PRODUCTS AND THIS MAY CAUSE CABLETRON TO LOSE MARKET SHARE OR SUFFER DECREASED REVENUES. Cabletron's competitors have pursued and are continuing to pursue a strategy of acquiring and investing in data networking companies possessing advanced networking technologies. This strategy helps Cabletron's competitors secure access to the advanced technologies under development by the data networking companies and enhances their ability to later acquire these companies. This strategy also deters other competitors, including Cabletron, from obtaining access to these companies' products or acquiring these companies. The acquisition of and investment in these companies allows Cabletron's 15 26 competitors to offer new products without the lengthy time delays that occur with internal product development and also permits potential competitors who lack data networking products and technologies to more quickly enter the data networking market. If Cabletron cannot acquire or invest in data networking companies, its access to commercially significant technologies may be limited and Cabletron may not be able to offer products to meet its customers' needs, causing Cabletron's market share to decline. Cabletron may have difficulty acquiring data networking companies because there is significant competition for these acquisitions, causing the prices paid to acquire data networking companies to be extremely high compared to the assets and sales of these companies. Cabletron's competitors may also have greater resources that enable them to compete more effectively for the acquisition of companies. - IF CABLETRON IS UNABLE TO SUCCESSFULLY INTEGRATE ACQUIRED COMPANIES, IT MAY NOT BE ABLE TO SUCCESSFULLY DEVELOP AND MARKET NEW PRODUCTS. Cabletron has partially addressed the need to develop new products by acquiring or investing in other data networking companies. These acquisitions and investments involve risks that include: - - difficulties in assimilating the operations, technologies and products of the acquired companies; - - the diversion of management's attention from other business concerns; - - entering markets in which competitors have established market positions; and - - the potential loss of key employees of the acquired company. The successful combination of companies in the high technology industry may be more difficult to accomplish than in other industries because these companies will require integration of product offerings and coordination of their sales and marketing and research and development efforts. - THE PERFORMANCE OF EARLY STAGE COMPANIES ACQUIRED BY CABLETRON COULD CAUSE CABLETRON'S OVERALL PERFORMANCE TO DECLINE. The acquisition of early stage companies involves risks that other acquisitions do not involve. These companies often have limited operating histories, limited or no prior sales, and may not have achieved profitability. The technologies possessed by these companies are often unproven and the development and marketing of products based upon these technologies may require the investment of substantial time and resources. Despite any investment of time and resources, Cabletron may not develop commercially viable or profitable products. Cabletron may also not experience revenues sufficient to justify its investment. If Cabletron engages in several acquisitions of early stage companies, these risks could be magnified. - IF CABLETRON IS UNABLE TO HIRE AND RETAIN KEY PERSONNEL ITS ABILITY TO COMPETE MAY BE HARMED. Cabletron's success depends greatly upon its key employees and management, including the presidents of the four new operating subsidiaries. Recruiting and retaining skilled personnel, including engineers, is highly competitive. If Cabletron cannot successfully recruit and retain skilled personnel, particularly engineers and sales personnel, its competitive position may be harmed and Cabletron may have difficulty managing its business and meeting key objectives on time. The volatility of Cabletron's common stock can also hamper Cabletron's ability to retain employees. When the Cabletron common stock price is less than the exercise price of stock options granted to employees, turnover is likely to increase, which could have a negative effect on Cabletron's operating results and financial condition. - THE MARKET PRICE OF CABLETRON'S COMMON STOCK IS VOLATILE AND HOLDERS OF CABLETRON COMMON STOCK MAY NOT BE ABLE TO RE-SELL THEIR SHARES AT OR ABOVE THEIR CURRENT VALUE, OR AT ALL. As is frequently the case with the stocks of high technology companies, the market price of the Cabletron's stock has been, and may continue to be, volatile. The price of Cabletron's common stock may be affected by: - - periodic fluctuations in results of operations; - - shortfalls in revenues or earnings from the levels anticipated by securities analysts and others; - - increased competition; 16 27 - - the introduction of new products by the Cabletron or its competitors; - - delays or difficulties in completing Cabletron's transformation into four new companies; - - changes in the mix of sales channels through which Cabletron's products and services are sold; - - the timing of significant customer orders; and - - U.S. and international business trends. The stock market has recently experienced extreme price and volume fluctuations, which have particularly affected the market price for many high-technology companies, but which have not necessarily been related to the operating performance of these companies. Past performance of Cabletron's stock price or of other technology companies' stock prices should not be considered a reliable indicator of future performance of Cabletron's stock price. - CABLETRON'S MARKET IS SUBJECT TO RAPID TECHNOLOGICAL CHANGE REQUIRING LARGE EXPENDITURES FOR RESEARCH AND DEVELOPMENT THAT MAY NOT RESULT IN INCREASED REVENUES. The market for networking products is subject to rapid technological change, evolving industry standards and frequent new product introductions requiring a high level of expenditures for research and development. Cabletron may be required to make significant expenditures to develop new integrated product offerings. If Cabletron encounters delays in developing or introducing new products or product enhancements or if the product enhancements do not gain market acceptance, Cabletron will have difficulty maintaining its competitive position. Even if Cabletron makes significant expenditures to develop new products, customer demand for products may not grow at the rate expected by Cabletron. Cabletron may also not be successful in developing, manufacturing and marketing new products or product enhancements that respond to customer demands or to evolving industry standards and technological change. Cabletron may experience difficulties that could delay or prevent the successful development, introduction, manufacture and marketing of these products. - IF CABLETRON IS UNABLE TO PROTECT ITS PROPRIETARY TECHNOLOGY IT MAY LOSE MARKET SHARE OR SUFFER DECREASES IN PROFITABILITY. Cabletron's success depends on its proprietary technology. Cabletron attempts to protect its proprietary technology through patents, copyrights, trademarks, trade secrets and license agreements. Cabletron's efforts may not be adequate to prevent misappropriation of its technology. Patents issued to Cabletron may be challenged, invalidated or circumvented. The laws of some foreign countries do not protect Cabletron's proprietary rights at the same level as do the laws of the United States. If Cabletron cannot protect its proprietary technology, it may suffer loss of market share, decreased sales or lower profitability. - CABLETRON COULD BE LIABLE FOR SUBSTANTIAL DAMAGES IF A THIRD PARTY SUCCESSFULLY ESTABLISHES THAT CABLETRON'S PRODUCTS INFRINGE ON THAT THIRD PARTY'S INTELLECTUAL PROPERTY RIGHTS. Although Cabletron does not believe that its products infringe the proprietary rights of any third parties, third parties have periodically asserted infringement and other claims against Cabletron and others could assert claims against Cabletron in the future. If these claims are successful, the party making the claims could obtain a judgment awarding substantial damages. This party could also obtain an order which could effectively block Cabletron's ability to license its products in the United States or abroad. Cabletron could also be required to license technology to replace its infringing technology at substantial cost and may be unable to license replacement technology at all. Cabletron could also incur substantial costs and diversion of management resources to defend any claims relating to proprietary rights even if Cabletron did ultimately prevail in the matter. - CABLETRON COULD BE FORCED TO ABANDON A SUCCESSFUL PRODUCT OFFERING IF A THIRD PARTY SUCCESSFULLY ESTABLISHED THAT CABLETRON'S PRODUCTS INFRINGE ON THE THIRD PARTY'S INTELLECTUAL PROPERTY RIGHTS. If a third party threatens to establish or successfully establishes that a Cabletron product infringes on that third party's intellectual property rights, Cabletron might be forced to abandon efforts to sell that product. If this were to happen, Cabletron's revenues or profitability could fall. 17 28 - DISRUPTIONS IN THE SUPPLY OF COMPONENTS USED BY CABLETRON TO MANUFACTURE ITS PRODUCTS COULD AFFECT CABLETRON'S ABILITY TO DELIVER ITS PRODUCTS IN A TIMELY AND COST-EFFECTIVE MANNER. Cabletron's products include components that are available from single or limited sources, some of which require long order lead times. Any reduction in supply, interruption or extended delay in timely supply, variances in actual needs from forecasts for long order lead time components, or change in costs of components could affect Cabletron's ability to deliver its products in a timely and cost-effective manner. With the increasing technological sophistication of new products and related design and manufacturing complexities, Cabletron anticipates that it may need to rely on additional single source or limited suppliers for components or manufacture of products and subassemblies. - DISRUPTIONS IN THE MANUFACTURE OF CABLETRON'S PRODUCTS COULD AFFECT CABLETRON'S ABILITY TO DELIVER ITS PRODUCTS ON TIME. Nearly all of Cabletron's products are manufactured by third-party contract manufacturers. The failure of a third-party manufacturer to manufacture the products, to meet Cabletron's manufacturing standards or to deliver the products in time for Cabletron to meet its delivery requirements could cause Cabletron to suffer reduced revenues and lose market share. RISK FACTORS RELATING TO INDUS RIVER As a stand-alone company, Indus River's business is subject to numerous risks and uncertainties, including those described below. Indus River's stockholders should understand that these risks will continue to apply to Indus River's business if the merger is not completed. - INDUS RIVER HAS EXPERIENCED SIGNIFICANT OPERATING LOSSES THROUGHOUT ITS HISTORY, EXPECTS THESE LOSSES TO CONTINUE AND MAY NOT ACHIEVE PROFITABILITY IN THE FUTURE. Since its formation on August 7, 1996, Indus River has incurred losses. Indus River incurred net losses of $7,039,360 in the year ending December 31, 1998, net losses of $9,766,791 in the year ending December 31, 1999 and net losses of $11,958,832 for the 10-month period ending October 31, 2000. As of October 31, 2000, Indus River had an accumulated deficit of $31.3 million. If Indus River fails to increase revenues substantially, it could fail to achieve profitability. - INDUS RIVER MAY NOT BE ABLE TO OBTAIN ADDITIONAL FINANCING WHEN NEEDED, WHICH COULD REDUCE ITS ABILITY TO FUND OR EXPAND OPERATIONS. If the merger with Cabletron is not completed and Indus River continues as a stand-alone company, Indus River would not have sufficient capital to continue its present business operations. As a stand-alone company, Indus River will need to obtain significant additional funds for research and development and working capital. If Indus River cannot obtain funds, it could be forced to curtail its future business operations, or seek combination with another company on terms less favorable than the terms of the merger with Cabletron. - INDUS RIVER MAY NOT BE ABLE TO PRODUCE SUFFICIENT REVENUES TO OPERATE ITS BUSINESS IF ITS PRODUCTS DO NOT ACHIEVE MARKET ACCEPTANCE. The success of Indus River's products depends on the ability to make potential customers recognize the advantages and cost-effectiveness of its virtual private network hardware and software products. Indus River does not have other products through which it can earn revenue. Many of its customers and potential customers have long-standing relationships with established competitors of Indus River. If Indus River is unable to achieve widespread acceptance of its products, it will have difficulty increasing its revenues. - INDUS RIVER'S LENGTHY SALES CYCLE MAKES IT DIFFICULT TO PREDICT QUARTERLY RESULTS AND MAY CAUSE OPERATING RESULTS TO VARY SIGNIFICANTLY. Indus River typically completes a sale of its product within four to nine months of the initial customer inquiry. Timing of customer purchase decisions is unpredictable and depends on a number of factors outside of Indus River's control, including the technical skills of the customer and its end-users, the size of the network being installed, the complexity of the network environment and the degree of hardware and software configuration required. If Indus River receives purchase orders for significant dollar amounts on an irregular and unpredictable basis, its business operations and financial condition could be harmed. 18 29 - INDUS RIVER EARNS MOST OF ITS REVENUE FROM A SMALL BASE OF CUSTOMERS AND ITS REVENUES MAY DECLINE SIGNIFICANTLY IF ANY CUSTOMER CANCELS OR DELAYS A PURCHASE OF INDUS RIVER'S PRODUCTS. Indus River anticipates that sales of its products to approximately 40 customers will account for a significant portion of its total revenue. If Indus River fails to make sales to a greater number of customers or loses any existing customers its results of operations and financial condition could be harmed. - INDUS RIVER FACES INTENSE COMPETITION AND FAILURE TO COMPETE SUCCESSFULLY COULD MAKE IT DIFFICULT FOR INDUS RIVER TO ACQUIRE AND RETAIN CUSTOMERS. Competitors in the virtual private network market include large companies such as Nortel, Cisco and Checkpoint Systems. Many of these competitors have substantially greater financial, technical, sales, marketing and other resources than Indus River. These competitors also have greater name recognition and larger customer bases. These competitors are able to devote greater resources to the development, promotion, sale and support of their products than Indus River. If Indus River is unable to compete efficiently, its ability to increase its revenue and market share may be harmed. - THE FAILURE OF INDUS RIVER'S SUPPLIERS TO MEET ITS MANUFACTURING NEEDS WOULD SERIOUSLY HARM ITS ABILITY TO TIMELY FILL CUSTOMER ORDERS. Indus River uses Avnet Applied Computing to supply server platforms and Lineo to supply its remote gateway products. If either of these suppliers terminates its relationship with Indus River or is unable to satisfy Indus River's supply requirements, Indus River's ability to fill customer orders on time, its reputation and its operating results will suffer. Qualifying new contract manufacturers and beginning production is expensive and time consuming, and changing contract manufacturers would disrupt Indus River's business, potentially causing Indus River to lose revenue. - THE LOSS OF KEY PERSONNEL COULD HARM INDUS RIVER'S ABILITY TO COMPETE. Indus River's success depends upon the continued contributions of key management, engineering, sales and marketing and manufacturing personnel. Competition for highly skilled personnel is intense and Indus River may not be successful in retaining its existing personnel or attracting additional key personnel. The loss of the services of key personnel, or the inability to attract and retain qualified personnel in the future, particularly engineers and sales personnel could harm Indus River's ability to manage its business and meet key objectives. - INDUS RIVER'S ABILITY TO RETAIN OR ATTRACT CUSTOMERS WILL SUFFER IF IT IS UNABLE TO RESPOND TO RAPID TECHNOLOGICAL CHANGE. The market for Indus River's virtual private network systems and other service delivery products is subject to rapid technological change. The introduction of new products by competitors, market acceptance of products based on new or alternative technologies or the emergence of new industry standards, could cause Indus River's existing or future products to be obsolete. - IF INDUS RIVER IS UNABLE TO PROTECT ITS PROPRIETARY TECHNOLOGY IT MAY BE UNABLE TO COMPETE EFFECTIVELY. Indus River relies on a combination of copyright, trademark and trade secret laws and restrictions on disclosure to protect its intellectual property rights. Indus River also enters into confidentiality or license agreements with its employees, consultants and business partners. Despite Indus River's efforts to protect its proprietary rights, unauthorized parties may attempt to copy or obtain and use its products or technology. Monitoring unauthorized use of Indus River's products is difficult, and if Indus River is unable to prevent unauthorized use of Indus River's technology, its business could be harmed. - IF INDUS RIVER IS UNABLE TO SUCCESSFULLY EXPAND ITS INTERNATIONAL OPERATIONS, IT MAY BE UNABLE TO SUCCESSFULLY COMPETE. Indus River has limited experience in marketing and distributing its products internationally and may be unable to develop international market demand for its products. Indus River may also not be able to take advantage of free local dialing and other key domestic market incentives for its product, which are unavailable internationally. 19 30 THE COMPANIES INDUS RIVER NETWORKS, INC. 31 Nagog Park Acton, Massachusetts 01720 (978) 266-8100 Indus River Networks designs, manufactures and markets enterprise-class network hardware and software that enables organizations of all sizes to install and manage remote access and site to site virtual private networks, or VPNs, with centralized control and remote enforcement of predefined network access policies.

Merely voting against the merger will not protect your rights to an appraisal. Annex B to this proxy statement/prospectus contains a copy of the Delaware statute governing appraisal rights. If you do not follow all the steps required by Delaware law, you will lose your rights to appraisal. The Delaware law requirements for exercising appraisal rights are described in further detail on pages 41 to 44. 23 34 THE MERGER The discussion below summarizes the material terms of the merger. We urge stockholders to read carefully the merger agreement, including the amendment to the merger agreement and the form of escrow agreement which are attached as annexes A and C to this proxy statement/prospectus. BACKGROUND TO THE MERGER At the end of 1999 and the beginning of 2000, management of Indus River made presentations to the Indus River board of directors about Indus River's business model and strategy. These presentations included the timing of and need for additional financing. They also discussed the desirability of identifying potential strategic partners or acquiring companies who could help Indus River reach a larger market for its existing and planned product offerings. At the request of the Indus River board of directors, Per A. Suneby, president and chief executive officer of Indus River and Stephen J. Ricci, a director of Indus River, interviewed several investment banking firms. On February 7, 2000, Indus River retained Deutsche Banc Alex.Brown as a financial advisor. Deutsche Banc was hired primarily to explore strategic alternatives which might lead to a possible sale, merger or joint venture transaction for Indus River and secondarily to advise on financial strategy and to provide assistance with a possible financing. The Indus River board of directors had determined that a sale, merger or a joint venture transaction had the potential to provide Indus River with greater resources to compete with some of its large competitors. Beginning in February 2000, representatives of Indus River and Cabletron held numerous discussions. The purpose of these discussions was to evaluate a range of possible business relationships between Cabletron and Indus River. On February 8, 2000, Garth Rose, vice president of business development for Indus River, and Dan Harding, vice president of business development for Cabletron, held a teleconference to discuss Cabletron's needs for virtual private network equipment. They discussed a range of issues surrounding Cabletron building a business relationship with Indus River. On February 9, 2000, a non-disclosure agreement was executed between Indus River and Cabletron. On February 16, 2000, representatives of Indus River, including Julian W. West, chief technology officer, David Zwicker, vice president of marketing, and Mr. Rose met in Acton, Massachusetts with representatives of Cabletron, including Mr. Harding, Graham Morrison, senior director of corporate development, Ken Pappas, director of wide area network access and virtual private network marketing, and Dick Bussiere, director of engineering. Michael Murray, managing director at Deutsche Banc was also present at the meeting. Indus River presented an overview of Indus River and its products, gave customer examples, and gave a product demonstration. On February 22, 2000, representatives of Indus River, including Mr. West, and Paul Jones, vice president of engineering, met with Mr. Bussiere, and Dana Cook from Cabletron in Acton, Massachusetts. Indus River held an in-depth engineering discussion and gave an in-depth product demonstration. About one week after this meeting, a RiverWorks VPN evaluation system was requested and was installed in Cabletron's offices in Rochester, New Hampshire. On February 25, 2000, Mr. Rose and Mr. West from Indus River met with John Roese, chief technology officer, Ron Oakley, vice president of information technology, Bill Burger, senior director service provider marketing, Mr. Pappas, Mr. Bussiere, and other technical representatives from Cabletron in Rochester, New Hampshire. The objective of the meeting was to demonstrate a typical Indus River sales call to an enterprise customer using Cabletron as the prospect. At the end of the meeting, Cabletron information technology representatives requested a second RiverWorks VPN evaluation system for internal use and testing. A lengthy technical discussion followed the mock sales call and Mr. Jones from Indus River joined that meeting. 24 35 On February 28, 2000, Mr. Rose and Mr. Morrison spoke about the status of the discussions between Indus River and Cabletron. Mr. Morrison asked several questions exploring Indus River's valuation expectations and indicated that Mr. Harding would be calling Deutsche Banc to discuss next steps. During the month of March 2000, numerous discussions occurred between Mr. Harding and Deutsche Banc, primarily with Mr. Murray. Discussions were generally about Cabletron's perception of Indus River's value and Indus River's valuation expectations. During this time, a second RiverWorks VPN system was installed in the Cabletron information technology department in Rochester, New Hampshire. During the months of February and March 2000, Indus River also engaged in strategic discussion with several other companies contacted through executives of Indus River and representatives of Deutsche Banc concerning possible acquisition, joint venture and original equipment manufacturer transactions. On March 27, 2000, Mr. Suneby, David Gamache, chief financial officer, and Mr. Rose of Indus River, and Robert Benner, managing director, Edward Arnstein, associate, and Mr. Murray from Deutsche Banc spoke with the Indus River board of directors to give them a merger and acquisition status update. The board was advised of Cabletron's interest and also about other companies that were expressing interest in Indus River. On March 28, 2000, Mr. Suneby, Mr. Gamache, and Mr. Rose, from Indus River and Mr. Benner from Deutsche Banc met with Mr. Harding and Mr. Roese from Cabletron in Acton, Massachusetts. Mr. Roese presented Cabletron's planned transformation of its four divisions and covered the plans surrounding an Enterasys transformation in detail. Mr. Roese discussed Enterasys' technology vision, internal organizational structure, and the synergy of merging Indus River into Enterasys. Mr. Harding discussed Cabletron's view of Indus River's value and proposed that the structure for the deal combine Cabletron shares and Enterasys warrants. The meeting ended with the understanding that Cabletron would submit a summary of proposed terms to Indus River within several days. On April 3, 2000, Mr. Harding of Cabletron and Mr. Murray talked on the phone. Cabletron had announced quarterly earnings and the status of the planned transformation of four divisions on March 31, 2000. The stock market reacted negatively to the news and Cabletron's stock price had dropped substantially. Mr. Harding indicated that these developments had delayed his preparation of a term sheet. On April 5, 2000, Mr. Harding of Cabletron wrote to Mr. Suneby of Indus River and stated that although Cabletron remained interested in Indus River, Cabletron was not then going to make an acquisition offer for Indus River. During April and May, Mr. Rose and multiple members of the Indus River customer service group actively supported the ongoing RiverWorks VPN evaluations at Cabletron. On June 2, 2000, Cabletron placed a purchase order for a 1,000 user RiverWorks VPN system for internal use at their Enterasys division. On June 6, 2000, Mr. Pappas and Mr. Bussiere from Cabletron met with Mr. Suneby, Mr. West, Mr. Gamache, Mr. Rose, and Mr. Zwicker from Indus River in Acton, Massachusetts. Mr. Pappas expressed interest in signing an original equipment manufacturer deal with Indus River and presented the advantages of an original equipment manufacturer deal with Enterasys. The Indus River team expressed a willingness to discuss an original equipment manufacturer transaction, but also openly questioned if that was the right kind of business relationship between Indus River and Enterasys. On June 22, 2000, Mr. Suneby, and Mr. Rose from Indus River, and Mr. Murray from Deutsche Banc met with Mr. Harding, Mr. Pappas, Mr. Bussiere, and Garry McGuire, vice president of worldwide marketing for Enterasys, in Andover, Massachusetts. The objective of the meeting was to do a full review and status update and to discuss a range of possible business relationships among Indus River, Cabletron and Enterasys. At the meeting Mr. Harding agreed that it made sense to re-explore acquisition as an option. Mr. Pappas asked questions about Indus River's site-to-site virtual private network capabilities and it was agreed to set up a demonstration of Indus River's new site-to-site functionality. 25 36 On June 27, 2000, Mr. Bussiere and Mr. Pappas from Cabletron and Enterasys met with Mr. West, Mr. Zwicker, Mr. Rose, Al Harper, vice president of sales, and several senior Indus River engineers in Acton, Massachusetts. They observed an in-depth demonstration of new site-to-site virtual private network functionality and said they were very pleased with the demonstration. Mr. Zwicker also presented a three-phase strategy of aggressively developing next-generation virtual private network products and quickly bringing them to market through Enterasys' sales channels. On June 30, 2000, Henry Fiallo, president of Enterasys, Mr. Harding, Mr. Pappas, Mr. Morrison, and Mr. Bussiere of Cabletron and Enterasys met with Mr. Suneby, Mr. West, Mr. Zwicker and Mr. Rose of Indus River in Andover, Massachusetts. Piyush Patel, chief executive officer of Cabletron, and Eric Jaeger, executive vice president of corporate affairs for Cabletron, joined the meeting by teleconference. Mr. Fiallo presented Enterasys' vision and the Indus River team presented Indus River's company history and vision of synergy with Enterasys. On July 7, 2000, Mr. Harding of Cabletron called Mr. Suneby of Indus River and indicated that Cabletron wanted to proceed with an acquisition of Indus River. From July 10 to July 12, 2000, multiple conversations occurred between Mr. Harding and Deutsche Banc discussing Cabletron's perception of Indus River's value and Indus River's valuation expectations. On July 12, 2000, Mr. Harding orally outlined to Mr. Benner the terms of an offer to acquire Indus River. On July 12, 2000, at a regularly scheduled meeting of the Indus River board of directors, Mr. Suneby, Mr. Gamache, and Mr. Rose and representatives of Deutsche Banc and McDermott, Will & Emery, Indus River's law firm, discussed the terms of Cabletron's oral offer to acquire Indus River. The representatives of Deutsche Banc presented information concerning Cabletron and Enterasys and information concerning Indus River's competitive position. The representative of McDermott, Will & Emery reviewed some of the legal issues that would have to be addressed in the transaction terms being proposed by Cabletron. After discussion and analysis, the board of directors recommended that Indus River proceed with the discussions with Cabletron. On July 13, 2000, Mr. Suneby and Mr. Zwicker of Indus River met with Mr. Jaeger, Mr. Harding, and Mr. Patel of Cabletron in Rochester, New Hampshire. The objective of the meeting was for Mr. Jaeger and Mr. Patel to become better acquainted with Mr. Suneby and Indus River. On July 19 and 21, 2000, Mr. Suneby, Mr. Gamache, Mr. Rose of Indus River and Mr. Benner of Deutsche Banc met with Mr. Harding of Cabletron at the offices of Ropes & Gray, Cabletron's law firm, in Boston, Massachusetts. Representatives of Ropes & Gray and McDermott, Will & Emery also participated in the meetings. The meetings focused on discussing and negotiating the details of the acquisition. On July 25, 2000, Cabletron submitted a written term sheet to Indus River outlining the terms of an acquisition of Indus River and a special meeting of the Indus River board of directors was held by teleconference to evaluate the term sheet. After discussion and analysis, all of the board members present expressed their approval of moving forward with negotiations with Cabletron. By a unanimous written consent circulated following the meeting, the board of directors authorized the execution of a letter of intent incorporating the term sheet presented by Cabletron. The letter of intent would be non-binding except for the establishment of an exclusive dealing period for the purpose of continuing negotiations and completing due diligence. On July 31, 2000, the letter of intent was executed. It provided for an exclusive dealing period through August 16, 2000. During the last week of July through August 18, 2000, ongoing discussions and negotiations continued primarily between Mr. Harding of Cabletron and Cabletron's legal counsel, Ropes & Gray, and Mr. Gamache of Indus River, Mr. Benner of Deutsche Banc and Indus River's legal counsel, McDermott, Will & Emery. Meetings were held at the offices of Ropes & Gray in Boston, Massachusetts. 26 37 During the week of August 7, 2000, Cabletron completed its business and technical due diligence. During that week, representatives of Ropes & Gray conducted legal due diligence of Indus River at the offices of Indus River in Acton, Massachusetts. On August 14, 2000, a special meeting of the Indus River board of directors was held. Representatives of Deutsche Banc and McDermott, Will & Emery reviewed the terms of the acquisition transaction which had been negotiated and which were substantially similar to the terms included in the letter of intent previously authorized by the board of directors. After discussion and analysis and consultation with Deutsche Banc and McDermott, Will & Emery and for the reasons described under "-- Reasons for the Merger and Board of Directors Recommendation" beginning on page 27 of this proxy statement/prospectus, the Indus River board of directors unanimously authorized management to execute the definitive merger agreement and related agreements. On August 16, 2000, the parties extended the exclusive dealing period through August 23, 2000. In the evening of August 18, 2000, a definitive merger agreement was signed by executives of Indus River and Cabletron. On August 21, 2000, before trading began on the New York Stock Exchange, Cabletron issued a press release announcing the execution of the merger agreement. On December 3, 2000, Indus River and Cabletron amended the merger agreement to extend the termination date to March 1, 2001 from January 15, 2001. REASONS FOR THE MERGER AND BOARD OF DIRECTORS RECOMMENDATION In reaching its decision to approve the merger agreement and the merger and to recommend adoption of the merger agreement by Indus River stockholders, the Indus River board of directors consulted with management, its financial and legal advisors and independently considered the proposed merger agreement and the transactions covered by the merger agreement. The discussion below of the factors considered by the Indus River board of directors in making its decision is not intended to be exhaustive but includes all significant factors considered by the Indus River board of directors. The Indus River board of directors considered the following factors as reasons that the merger will be beneficial to Indus River and its stockholders: - The financial resources of Cabletron and its ability to fund the continued development of Indus River's virtual private network product suite; - The access afforded to Indus River's products through Enterasys' established relationships with large business organizations and enterprises and with major customers, sales and marketing resources and distribution channels; - The strategic fit and complementary nature of Indus River's product suite with Enterasys' security strategy and equipment and hardware; and - The belief that an exchange of Indus River stock for shares of Cabletron common stock and Cabletron series C preferred stock would provide Indus River stockholders with greater future liquidity in a company that could potentially capitalize on the business prospects of Indus River and provide a better return on stockholder investment. The Indus River board of directors reviewed with Indus River management: - Information relating to the business, assets, management, competitive position and operating performance of Indus River, including the prospects of Indus River if it were to continue as an independent company and its requirements for additional funding; - The strategic importance of securing a larger partner for Indus River to better exploit the potential market for virtual private networks and take advantage of Indus River's technological leadership in virtual private networks; 27 38 - The market price and anticipated stability of Cabletron stock; - The likelihood that the merger would be completed; and - The expected qualification of the merger as a reorganization under section 368(a) of the Internal Revenue Code. The Indus River board of directors also identified and considered a number of potentially negative factors in its deliberations concerning the merger, including: - The risk that the operations of Enterasys and Indus River might not be successfully integrated; - The risk that, despite the efforts of Indus River and Enterasys after the merger, key personnel might leave Indus River; - The risk that the potential benefits of the merger might not be fully realized; and - The risk that the market price for Cabletron stock might decline. The Indus River board of directors believed that some of these risks were unlikely to occur, that Indus River could avoid or mitigate others, and that, overall, these risks were outweighed by the potential benefits of the merger. In view of the variety of factors considered in its evaluation of the merger agreement and the merger, the Indus River board of directors did not find it practicable to quantify or assign relative weight to the specific factors considered in reaching its determination. Individual members of the Indus River board of directors may have given different weight to different factors. Recommendation of the Indus River Board of Directors. After careful consideration, the Indus River board of directors unanimously determined that the terms of the merger agreement and the merger are advisable and fair to, and in the best interests of, Indus River and its stockholders and has unanimously approved the merger agreement and the merger. The Indus River board of directors unanimously recommends that the stockholders of Indus River vote for adoption of the merger agreement. APPRAISALS OF CABLETRON SERIES C PREFERRED STOCK BY ADAMS, HARKNESS & HILL, INC. The merger agreement specifies that the number of shares of Cabletron stock issued in the merger that will constitute the liquidation preference payment will be determined based on a 10 trading day average closing price of Cabletron's common stock and an appraised value of the Cabletron series C preferred stock as of five trading days before the closing date of the merger. Adams, Harkness & Hill, Inc. has agreed to deliver this appraisal at the closing. Indus River selected Adams, Harkness & Hill to deliver the appraisal for a number of reasons, including Adams, Harkness & Hill's qualifications, expertise and reputation in the area of valuation and financial advisory work. Indus River placed greatest emphasis on Adams, Harkness & Hill's reputation as a nationally recognized investment banking firm and the fact that Adams, Harkness & Hill is regularly engaged in the valuation of businesses and their securities in mergers, acquisitions, leveraged buyouts, underwritings, private placements and valuations for corporate and other purposes. At the request of Indus River, Adams, Harkness & Hill has also delivered the preliminary appraisal attached as annex F to this proxy statement/prospectus. The sole purpose of this preliminary appraisal is to include in this proxy statement/prospectus, an illustration of the distribution of the shares of Cabletron common stock and Cabletron series C preferred stock to be issued in the merger. Adams, Harkness & Hill expects that the types of information obtained by and the valuation methodologies used by it in delivering its final appraisal will be similar to those used in delivering its preliminary appraisal. The valuation determined in the final appraisal may be materially different from that determined in the preliminary appraisal. On December 5, 2000, Adams, Harkness & Hill delivered its preliminary appraisal that the aggregate fair market value of the Cabletron series C preferred stock to be received by the Indus River stockholders in 28 39 the merger was approximately $24.32 million as of December 4, 2000, based upon and subject to the various considerations described in the preliminary appraisal. The full text of Adams, Harkness & Hill's preliminary appraisal, dated December 5, 2000, is attached as annex F to this proxy statement/prospectus and is incorporated in this proxy statement/prospectus by reference. The preliminary appraisal describes the assumptions made, procedures followed, matters considered and limitations on the scope of the review undertaken by Adams, Harkness & Hill in delivering the preliminary appraisal. Adams, Harkness & Hill's appraisal is directed to the board of directors of Indus River and addresses only the fair market value of the Cabletron series C preferred stock to be received under the merger agreement and does not address any other aspect of the merger or constitute a recommendation to any holder of Indus River stock about how to vote at the Indus River stockholder meeting. The following summary of Adams, Harkness & Hill's preliminary appraisal is qualified in its entirety by reference to the full text of the preliminary appraisal. The discussion below is a summary of the various sources of information and valuation methodologies used by Adams, Harkness & Hill in appraising the fair market value of the Cabletron series C preferred stock. To determine the fair market value of these securities, Adams, Harkness & Hill employed analyses based on: - The financial performance and relative valuations of selected public companies considered to be comparable to Enterasys; and - Discounted cash flow analysis of Enterasys. In preparing its analysis, Adams, Harkness & Hill: - Reviewed publicly available information concerning the business and operations of Cabletron and Enterasys, including Cabletron's recent filings with the Securities and Exchange Commission; - Reviewed the merger agreement in the form presented to the Indus River board of directors; - Compared the financial position and operating results of Enterasys with those of other publicly traded companies that Adams, Harkness & Hill considered to be relevant; and - Held discussions with members of Enterasys' management concerning Enterasys' historical and current financial condition and operating results, and its future prospects. Adams, Harkness & Hill also reviewed relevant industry market research studies, company research reports and general stock market performance. Other than the information discussed above, Adams, Harkness & Hill did not review any additional information in preparing its preliminary appraisal that was independently material to its analysis. The Indus River board of directors did not place any limitation on the procedures followed or factors considered by Adams, Harkness & Hill in delivering its preliminary appraisal. In delivering its preliminary appraisal, Adams, Harkness & Hill assumed and relied upon the accuracy and completeness of all of the financial and other information that was publicly available or provided to Adams, Harkness & Hill by, or on behalf of, Enterasys, and did not independently verify that information. Adams, Harkness & Hill assumed that projections and assumptions were reasonably prepared on a basis not materially different from the best currently available estimates and judgments of the management of Enterasys about the future operating and financial performance of Enterasys. Adams, Harkness & Hill did not obtain an independent evaluation or appraisal of any of the assets or liabilities, whether or not contingent, of Cabletron or Enterasys. Adams, Harkness & Hill's preliminary appraisal was based on economic, market, and financial information existing on, and available to, Adams, Harkness & Hill as of the date of its preliminary appraisal. Adams, Harkness & Hill's preliminary appraisal did not predict or take into account any possible economic, monetary or other changes which may occur, or information which may become available, after the date of its preliminary appraisal. 29 40 Public Company Peer Analysis -- Enterasys Adams, Harkness & Hill established a group of publicly traded companies to address the business areas in which Enterasys operates. The peer group consists of: - 3Com Corporation - ADTRAN, Inc. - Alcatel SA - Applied Digital Solutions - Cisco Systems, Inc. - Copper Mountain Networks, Inc. - Extreme Networks, Inc. - Avaya, Inc. - Marconi, plc - Nortel Networks Corporation - Tut Systems, Inc. Adams, Harkness & Hill compared financial measures and metrics of Enterasys with the financial measures and metrics of the peer group companies. The information included: market capitalization; enterprise value, calculated in the manner described below; price/projected 2000 & 2001 earnings ratios; 2001 projected revenue; last twelve months revenue; enterprise value/2001 projected revenue; enterprise value/last twelve months revenue; last twelve months operating margin; last twelve months gross margin; and year/year quarterly revenue growth. Enterprise value/2001 projected revenue and price/projected 2000 & 2001 earnings ratios imply the range of value that public markets place on companies in a particular market segment. Adams, Harkness & Hill employed an enterprise value valuation in this analysis because this methodology implies value based on a company's operations, regardless of how the company finances those operations. To determine enterprise value, market capitalization is calculated as the product of a company's common stock price per share multiplied by the number of diluted shares outstanding. Adams, Harkness & Hill used a 20 trading day average ending December 4, 2000, for all public company compatible analyses. The market capitalization is then adjusted for a company's debt and cash positions by adding the debt balance and subtracting the cash balance to arrive at an enterprise value. Stated mathematically, enterprise value has been calculated as: (market value of equity) + (debt) - (cash, cash equivalents and short-term investments) The low, high and mean financial ratios for the peer group companies are listed in the table below:
MULTIPLE LOW HIGH AVERAGE -------- --- ----- ------- Enterprise Value/2001 Projected Revenue..................... 0.5 12.7 4.3 2001 Price/Projected Calendar Year 2001 Earnings............ 9.1 108.4 45.9
To arrive at Enterasys' price/earnings multiples for calendar year 2001, Adams, Harkness & Hill relied on guidance from Enterasys' management as a check to validate published external research analysts' projections. Adams, Harkness & Hill then compared the gross margins of the peer group companies to Enterasys' estimated gross margins to narrow the peer group companies to a set of more truly comparable companies. This group of comparable peer group companies consists of: - ADTRAN, Inc. - Avaya, Inc. - Copper Mountain Networks, Inc. 30 41 - Extreme Networks, Inc. - Nortel Networks Corporation - Tut Systems, Inc. The low, high and mean financial ratios for the comparable peer group companies are listed in the table below:
MULTIPLE LOW HIGH AVERAGE -------- --- ----- ------- Enterprise Value/2001 Projected Revenue..................... 0.5 11.3 3.3 Price/Projected 2000 to 2001 Earnings Ratios................ 9.1 108.4 39.6
Applying the mean enterprise value/2001 projected revenue and price/projected 2000 & 2001 earnings ratio multiples of the comparable peer group companies to Enterasys' calendar year 2001 projected revenue of $915 million and calendar year 2001 projected earnings of $51.0 million, Adams, Harkness & Hill calculated the following implied estimated enterprise values for Enterasys: IMPLIED ENTERASYS ENTERPRISE VALUE MULTIPLE (IN MILLIONS) -------- ----------------- Enterprise Value/2001 Projected Revenue..................... $3,017 Price/Projected 2000 to 2001 Earnings Ratios................ $2,019 Since Enterasys is not a publicly traded company, Adams, Harkness & Hill applied an illiquidity discount to the implied enterprise values arrived at using these multiples. Based upon historical studies, Adams, Harkness & Hill used illiquidity discounts ranging between 30 - 40% to arrive at the following adjusted implied range of enterprise values for Enterasys:
IMPLIED ENTERASYS ENTERPRISE VALUES WITH ILLIQUIDITY DISCOUNT (IN MILLIONS) -------------------------- MULTIPLE 40% 35% 30% -------- ------ ------ ------ Enterprise Value/2001 Projected Revenue multiple......... $1,810 $1,961 $2,112 Price/Projected 2000 to 2001 Earnings Ratios............. $1,211 $1,312 $1,413
Discounted Cash Flow Analysis Adams, Harkness & Hill performed a discounted cash flow analysis to estimate the present value of the stand-alone unlevered after-tax cash flows of Enterasys. This means they analyzed after-tax cash flows before interest expense of Enterasys. To perform the discounted cash flow analysis, Adams, Harkness & Hill used the following data sources and assumptions: - Management projections for revenue, gross margin, and operating margin; - Projections by equity analysts of future Enterasys revenue growth; - Enterasys beta, estimated based on the historical behavior of the peer group companies and market research analyst estimates; - Terminal value based upon 7.5 - 8.5% perpetual growth applied to projected 2005 cash flow; and - Cost of capital for Enterasys calculated using a risk free rate of 5.75% and a market risk premium of 7.0%. To determine a range of net present values for Enterasys, Adams, Harkness & Hill performed a sensitivity analysis isolating two key variables: the five-year annualized revenue growth rate, focusing on growth rates between 20-30%, and the terminal value growth rate, focusing on growth rates between 7.5% and 8.5%. Adams, Harkness & Hill used these variables to calculate the following implied range of enterprise values for Enterasys: 31 42 SUMMARY CHART OF DISCOUNTED CASH FLOW RANGE AND RESULTING IMPLIED VALUE
LOW MIDPOINT HIGH ------ -------- ------ Enterprise Value ($ in millions)........................ $3,175 $3,968 $4,980
Conclusion To arrive at a preliminary appraised value for the shares of Cabletron series C preferred stock to be received by the Indus River stockholders in the merger, Adams, Harkness & Hill: - Identified the high, low and midpoint valuations determined from the two multiples analysis and the discounted cash flow analysis; - Performed a weighted average calculation, assigning a 2x weight to each midpoint value from each analysis; and - Multiplied the resulting value by 1%. Taken together, the information and analyses employed by Adams, Harkness & Hill lead to Adams, Harkness & Hill's overall conclusion that, for purposes of the preliminary appraisal, the aggregate fair market value of the 50,000 shares of Cabletron series C preferred stock to be issued in the transaction as of December 4, 2000 is $24.32 million, or $486.40 per share of Cabletron series C preferred stock. INTERESTS OF INDUS RIVER DIRECTORS, MANAGEMENT AND EMPLOYEES IN THE MERGER In considering the recommendation of the Indus River board of directors in favor of the merger, you should be aware that some directors, executive officers and employees of Indus River have interests in the merger that are different from the interests of stockholders of Indus River generally. These interests relate to or arise from: - the continued indemnification of current directors and officers and some employees of Indus River; - the retention of some current officers as employees of Cabletron or Enterasys; - accelerated vesting of rights relating to shares of other Indus River common stock, or Cabletron restricted stock substituted for the Indus River common stock, acquired or to be acquired by executives and employees of Indus River subject to stock option agreements or restricted stock purchase agreements with Indus River; - the grant of additional Indus River stock options to employees who were granted options on May 11, 2000, which contain a two-year vesting term, in exchange for their agreement to modify the accelerated vesting provisions for those options; and - the potential payment of additional bonuses to Indus River employees following the merger. Except as described below those persons have, to the knowledge of Cabletron and Indus River, no material interest in the merger apart from those of stockholders generally. The Indus River board of directors was aware of, and considered the interests of, their directors, executive officers, employees and stockholders when it approved the merger agreement and the merger. INDEMNIFICATION AND INSURANCE. The merger agreement provides that Cabletron will, or will cause the surviving corporation to, fulfill and honor all rights to indemnification or exculpation now existing in favor of the employees, directors or officers of Indus River. These indemnification rights are provided in: the Indus River certificate of incorporation and the Indus River by-laws as these documents existed on August 18, 2000. Cabletron will maintain for six years after the merger executive risk liability insurance for employees, directors and officers for acts or omissions of those persons occurring before the merger under terms and conditions at least as favorable as Indus River's executive risk liability insurance policy in effect on August 18, 2000. INDUS RIVER EXECUTIVE OFFICERS. It is anticipated that some Indus River executive officers will become employees of Cabletron after the merger. 32 43 EMPLOYEE BENEFITS. Cabletron has agreed to provide employee benefit plans, programs and arrangements to those individuals who will continue to be employees of Indus River after the merger. Cabletron has also agreed that: - the eligibility of each employee of Indus River, and that employee's spouse and dependents, to participate in Cabletron's welfare plans after the effective time of the merger will be determined without considering any preexisting condition, waiting period, actively-at-work, or similar exclusion or condition except for any condition or exclusion to which the employee is subject under the applicable welfare plan of Indus River before the effective time of the merger; - employees of Indus River will receive credit under the Cabletron welfare plans in which they participate after the effective time of the merger toward coinsurance and deductibles for any payments made by them during the calendar year in which the merger occurs under the applicable welfare plans of Indus River; and - after the merger, employees of Indus River will receive credit, for purposes of determining eligibility for or vesting under its retirement, welfare, vacation and similar plans or policies, for service with Indus River before the effective time of the merger. If Cabletron so requests, Indus River will cause its 401(k) plan to be terminated before the completion of the merger. Cabletron will then cause its 401(k) plan to accept rollover distributions from Indus River's terminated plan. EMPLOYEE ARRANGEMENTS. Per A. Suneby, the president and chief executive officer of Indus River and Julian W. West, the chief technology officer of Indus River, have entered into employment terms with the surviving corporation and will, as part of their compensation packages, receive options to purchase 200,000 shares of Enterasys stock. Those options will vest 25 percent after one year and then monthly for a period of three years. STOCK OPTIONS AND RESTRICTED STOCK AGREEMENTS Under the merger agreement, Cabletron will assume the Indus River stock incentive program and all stock options granted under that plan. Each stock option outstanding under the plan at the effective time of the merger will be converted into a stock option to acquire Cabletron common stock and Cabletron series C preferred stock on the same terms and conditions as applied to the Indus River stock option. The exact conversion rate will not be known until five trading days before the closing date of the merger. The number of shares of Cabletron common stock to be issued for each Indus River stock option will be equal to the product of: - the number of shares of Indus River common stock that would be issued for that option multiplied by - the number of shares of Cabletron common stock issuable in exchange for each share of Indus River common stock in the merger, rounded down to the nearest whole share. The number of shares of Cabletron series C preferred stock to be issued for each Indus River stock option will be equal to: - the number of shares of Indus River common stock that would be issued for that option, multiplied by - the number of shares of Cabletron series C preferred stock issuable in exchange for each share of Indus River common stock in the merger, rounded down to the nearest whole share. 33 44 The exercise price per Cabletron option issued in exchange for Indus River stock options will be equal to the sum of: - the product of: - the exercise price per share of Indus River common stock for that option immediately before the merger divided by the number of shares of Cabletron common stock issuable in exchange for each share of Indus River common stock in the merger, multiplied by - the ratio of the total fair market value, determined as of the ten trading days ending on and including the fifth trading day before the closing date of the merger, of the Cabletron common stock issuable in the merger to the total fair market value of all Cabletron stock issued in the merger; and - the product of: - the exercise price per share of Indus River common stock for that option immediately before the merger divided by the number of shares of Cabletron series C preferred stock issuable in exchange for each share of Indus River common stock in the merger, multiplied by - the ratio of the total fair market value, determined as of the fifth trading day before the closing date of the merger, of the Cabletron series C preferred stock issuable in the merger to the total fair market value of all Cabletron stock issued in the merger, rounded up to the nearest cent. Based on an average closing price of $17.89 per share of Cabletron common stock for the ten trading days ending on and including December 4, 2000 and an appraised value of $486.40 per share of Cabletron series C preferred stock as of December 4, 2000, as determined by Adams, Harkness & Hill, each Indus River stock option would convert into an option to purchase 0.00205897 shares of Cabletron common stock and 0.16471791 shares of Cabletron series C preferred stock at an average per share exercise price of $0.90. This calculation assumes that the closing of the merger occurs on January 10, 2001. As of the record date, the number of shares of Indus River common stock reserved for issuance under outstanding Indus River stock options under the plan was 2,088,625. After the merger, each restricted stock agreement between an Indus River stockholder and Indus River and each stock option agreement between an Indus River option holder and Indus River will be assumed by Cabletron, subject to the same restrictions and vesting provisions contained in the related Indus River restricted stock or stock option agreement, as any of those agreements may be amended before the merger. Subject to completion of the merger, some of Indus River's employees have agreed to modify the terms of their stock options issued on May 11, 2000, which contain a two-year vesting term, by agreeing to forfeit their right to acceleration for 50% of the shares subject to those options. This acceleration would have been triggered by the merger. In exchange for forfeiting this right, those employees will receive additional grants of stock options that will vest 50 percent on August 21, 2001, with the remaining 50 percent vesting in three equal installments on the last day of each three-month period after August 21, 2001, so long as the employee remains employed by the surviving corporation or any successor in interest. Cabletron will prepare and file with the Securities and Exchange Commission an appropriate registration statement registering the shares of Cabletron common stock and the shares of Cabletron series C preferred stock subject to the assumed Indus River stock options. The registration statement will be kept effective and current under the requirements of the Securities Act and the Securities Exchange Act of 1934, for so long as any assumed Indus River options remain outstanding. ACCOUNTING TREATMENT The merger will be accounted for under the purchase method of accounting under generally accepted accounting principles. Cabletron expects a significant portion of the purchase price to be allocated to goodwill and identifiable intangible assets. Under the purchase method, Cabletron will determine the fair value of 34 45 assets acquired on liabilities assumed. Any premium paid over fair value will be reflected on Cabletron's balance sheet as an intangible asset. FORM OF THE MERGER Subject to the terms and conditions of the merger agreement and the requirements of Delaware law, Acton Acquisition Co., a wholly owned subsidiary of Cabletron, will merge with and into Indus River. Indus River will be the surviving corporation of the merger and a wholly owned subsidiary of Cabletron, and will continue under the same name. MERGER CONSIDERATION Cabletron will issue an aggregate of 4,000,000 shares of Cabletron common stock and 50,000 shares of Cabletron series C preferred stock in exchange for all of the shares of Indus River preferred stock, Indus River common stock, and all options and warrants to purchase Indus River stock. Cabletron will also reserve for issuance approximately 100,000 additional shares of Cabletron common stock and 1,100 additional shares of Cabletron series C preferred stock to be issued to holders of additional options granted in exchange for the forfeiting of acceleration rights described above and some options granted to some employees hired by Indus River after August 18, 2000. The exact exchange rate will not be known until five trading days before the closing date of the merger. Based on an average price of $17.89 per share of Cabletron common stock for the ten trading days ending on and including December 4, 2000 and an appraised value of $486.40 per share of Cabletron series C preferred stock as of December 4, 2000, as determined by Adams, Harkness & Hill, this represents an aggregate of approximately $98 million in total consideration to be paid by Cabletron in the merger. At the effective time of the merger, each holder of Indus River preferred stock will receive the liquidation preference specified in the Indus River certificate of incorporation: - holders of Indus River series A preferred stock will receive $1.00 per share of Indus River series A preferred stock, plus all accrued but unpaid dividends - holders of Indus River series B preferred stock will receive $2.72 per share of Indus River series B preferred stock, plus all accrued but unpaid dividends - holders of Indus River series C preferred stock will receive $4.08 per share of Indus River series C preferred stock, plus all accrued but unpaid dividends - holders of Indus River series D preferred stock will receive $5.34 per share of Indus River series D preferred stock, plus all accrued but unpaid dividends Cabletron will pay this liquidation preference in shares of Cabletron common stock and Cabletron series C preferred stock. The value of Cabletron common stock and Cabletron series C preferred stock paid for the liquidation preference will be determined based on the average closing price of Cabletron common stock on the New York Stock Exchange for the ten trading days ending on and including the fifth trading day before the closing date of the merger, and the appraised fair market value of the series C preferred stock determined as of the fifth trading day before the closing date of the merger by Adams, Harkness & Hill. Cabletron will issue cash for any fractional shares of Cabletron common stock or Cabletron series C preferred stock that Indus River preferred stockholders would be entitled to receive as part of the liquidation preference payment. After the liquidation preference is paid, each holder of Indus River common stock and each holder of Indus River preferred stock will receive, in exchange for the Indus River shares held by that holder, shares of Cabletron series C preferred stock and shares of Cabletron common stock for each share of Indus River stock, whether common stock or preferred stock. The exact exchange rate will not be known until five trading days before the closing date of the merger because it is depends on the average closing price of Cabletron common stock for the ten trading days ending on and including the fifth trading day before the closing date of the merger, and the fair market value of Cabletron series C preferred stock determined as of the fifth trading day before the closing date of the merger by an appraisal conducted by Adams, Harkness & Hill, both of which 35 46 may fluctuate. The market price of Cabletron common stock and the fair market value of Cabletron series C preferred stock will affect the number of shares paid to the holders of Indus River preferred stock as the liquidation preference payment, which will in turn affect the number of shares to be issued to each holder of Indus River common stock and Indus River preferred stock. Cabletron will issue cash for any fractional shares that Indus River stockholders would be entitled to receive in the merger. Based on an average closing price of $17.89 per share of Cabletron common stock for the ten trading days ending on and including December 4, 2000, and an appraised value of $486.40 per share of Cabletron series C preferred stock as of December 4, 2000, as determined by Adams, Harkness & Hill, and assuming that the closing of the merger occurs on January 10, 2001 and a warrant to purchase 60,847 shares of Indus River series D preferred stock is not exercised before the merger, 15,423 shares of Cabletron series C preferred stock and 1,233,839 shares of Cabletron common stock will be issued to Indus River preferred stockholders to pay the liquidation preference. After the payment of the liquidation preference: - each holder of Indus River series A preferred stock would receive 0.00271557 shares of Cabletron series C preferred stock and 0.21724568 shares of Cabletron common stock for each share of Indus River series A preferred stock held by that holder; - each holder of Indus River series B preferred stock would receive 0.00373338 shares of Cabletron series C preferred stock and 0.29867074 shares of Cabletron common stock for each share of Indus River series B preferred stock held by that holder; - each holder of Indus River series C preferred stock would receive 0.00448167 shares of Cabletron series C preferred stock and 0.35853378 shares of Cabletron common stock for each share of Indus River series C preferred stock held by that holder; - each holder of Indus River series D preferred stock issued on June 30, 1999 would receive 0.00514313 shares of Cabletron series C preferred stock and 0.41145079 shares of Cabletron common stock for each share of Indus River series D preferred stock held by that holder; - each holder of Indus River series D preferred stock issued on July 8, 1999 would receive 0.00513886 shares of Cabletron series C preferred stock and 0.41110886 shares of Cabletron common stock for each share of Indus River series D preferred stock held by that holder; and - each holder of Indus River common stock would receive 0.00205897 shares of Cabletron series C preferred stock and 0.16471791 shares of Cabletron common stock for each share of Indus River common stock held by that holder. Upon completion of the merger, all shares of Indus River stock will no longer be outstanding, will automatically be canceled and will cease to exist. Each holder of a certificate representing shares of Indus River stock, other than shares for which appraisal rights have been properly exercised, will cease to have any rights as a stockholder of Indus River except the right to receive Cabletron common stock and Cabletron series C preferred stock, and to receive cash for any fractional share of Cabletron common stock or series C preferred stock that the holder would be entitled to receive. The total number of shares of Cabletron common stock and Cabletron preferred stock to be paid in the merger was determined through arm's-length negotiations between Cabletron and Indus River. CONVERSION OF SHARES; PROCEDURES FOR EXCHANGE OF CERTIFICATES; FRACTIONAL SHARES The conversion of Indus River stock into the right to receive Cabletron series C preferred stock and Cabletron common stock will occur automatically at the effective time of the merger. As of the effective time of the merger, Cabletron will deposit with Boston Equiserve, or another institution selected by Cabletron, the exchange agent, for the benefit of the holders of Indus River stock, certificates representing the shares of the Cabletron common stock to be issued under the merger agreement, less the number of shares of Cabletron common stock to be deposited in an escrow account to secure the indemnification obligations of the Indus River stockholders to Cabletron. After the merger, Cabletron will deposit all of the shares of Cabletron series C preferred stock to be issued under the merger agreement into a separate escrow account. The 36 47 Cabletron series C preferred stock will be held in the escrow account until the earliest to occur of the 30 month anniversary of the closing date of the merger or any conversion or redemption of those shares. As soon as possible after the merger, the exchange agent will send a transmittal letter to each Indus River stockholder. The transmittal letter will contain instructions for obtaining shares of Cabletron common stock and Cabletron series C preferred stock in exchange for shares of Indus River stock. PLEASE DO NOT SEND STOCK CERTIFICATES WITH THE ENCLOSED PROXY CARD. After the merger, each certificate that previously represented shares of Indus River stock will represent only the right to receive the Cabletron series C preferred stock and Cabletron common stock into which those shares were converted in the merger and the right to receive cash for any fractional share of Cabletron series C preferred stock and Cabletron common stock as described below. Until holders of certificates previously representing Indus River stock or the purchase of that stock have surrendered those certificates to the exchange agent for exchange, holders will not receive dividends or distributions on the Cabletron series C preferred stock and the Cabletron common stock into which those shares have been converted with a record date after the merger, and will not receive cash for any fractional shares of Cabletron series C preferred stock and the Cabletron common stock they would be entitled to receive. When holders surrender those certificates, they will receive any unpaid dividends and any cash for any fractional share of Cabletron series C preferred stock and the Cabletron common stock they would be entitled to receive without interest. Upon surrender of certificates previously representing Indus River stock, and the letter of transmittal described above properly executed and any other documents the exchange agent may reasonably require, the holder will be entitled to receive: - a certificate representing the number of whole shares of Cabletron common stock into which the Indus River stock, represented by the surrendered certificates, will have been converted at the effective time of the merger, less the number of shares of Cabletron common stock, if any, to be deposited in the escrow account on behalf of the holder; - notice of the number of whole shares of Cabletron series C preferred stock into which the Indus River stock, represented by the surrendered certificates, will have been converted at the effective time of the merger, and that those shares of Cabletron series C preferred stock have been deposited into an escrow account on behalf of the holder; and - cash instead of any fractional share of Cabletron common stock or Cabletron series C preferred stock, calculated in the manner described in the merger agreement and described below. If there is a transfer of ownership of Indus River stock which is not registered in the records of Indus River's transfer agent, certificates representing the proper number of shares of Cabletron common stock and Cabletron series C preferred stock may be issued to a person other than the person in whose name the certificate so surrendered is registered if: - that certificate is properly endorsed and in proper form for transfer; and - the person requesting the issuance: - - pays to the exchange agent any transfer or other taxes resulting from the issuance of shares of Cabletron stock in a name other than that on the surrendered certificate; or - - establishes to the satisfaction of Cabletron or any agent designated by it that the tax has been paid or is not payable. All shares of Cabletron common stock and Cabletron series C preferred stock issued upon conversion of shares of Indus River stock, including any cash paid for any fractional share of Cabletron stock or Cabletron series C preferred stock, will be issued in full satisfaction of all rights relating to those shares of Indus River stock. 37 48 No fractional share of Cabletron common stock or Cabletron series C preferred stock will be issued to any Indus River stockholder upon surrender for exchange of certificates previously representing Indus River stock. Instead of any fractional share of Cabletron common stock, the Indus River stockholder will receive cash equal to the product obtained by multiplying: - the average closing price for a share of Cabletron common stock on the New York Stock Exchange Composite Transactions Tape for the ten trading days ending on and including the fifth trading day before the closing date of the merger by - the fractional share which the stockholder would be entitled to receive. Instead of any fractional share of Cabletron series C preferred stock, the Indus River stockholder will receive cash equal to the product obtained by multiplying: - the fair market value per share of Cabletron series C preferred stock determined as of the fifth trading day before the closing date of the merger, by an appraisal conducted by Adams, Harkness & Hill by - the fractional share to which the stockholder would be entitled to receive. EFFECTIVE TIME OF THE MERGER The merger will become effective upon the filing of a certificate of merger with the secretary of state of the State of Delaware, or at a later time stated in the certificate of merger or agreed upon by Cabletron and Indus River. The filing of a certificate of merger will occur at the time of the closing of the merger. STOCK EXCHANGE LISTING OF CABLETRON COMMON STOCK It is a condition to completion of the merger that the Cabletron common stock issued to Indus River stockholders in the merger be authorized for listing on the New York Stock Exchange, subject to official notice of issuance. EMPLOYMENT AGREEMENTS It is a condition to the merger that Per A. Suneby and Julian W. West, the president and chief executive officer and chief technology officer of Indus River enter into employment agreements with the surviving corporation and that those agreements be in full force and effect at the effective time of the merger. SIGNIFICANT UNITED STATES FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER The following summary discusses the material federal income tax consequences of the merger to the stockholders of Indus River. This summary is not a complete description of all the tax consequences of the merger and does not address the tax consequences that may be relevant to particular categories of stockholders subject to special treatment under federal income tax laws, such as dealers in securities, banks, insurance companies, tax-exempt organizations, corporate stockholders that are collapsible corporations, non-United States persons, stockholders who acquired shares of Indus River common stock by exercising options or in another manner as compensation, holders of options, warrants or similar rights to acquire Indus River stock, stockholders who are subject to the alternative minimum tax provisions of the Internal Revenue Code of 1986, or stockholders who hold their shares as part of a hedging, straddle, conversion or other risk reduction or constructive sale transaction. This summary is based upon the Internal Revenue Code, applicable Treasury regulations, published administrative rulings and court decisions all as of the date of this proxy statement/prospectus. All of these items are subject to change either prospectively or retroactively, and any change could affect the continuing validity of the tax consequences described below. No information is provided in this proxy statement/ prospectus about the tax consequences of the merger arising under the laws of any state, local or foreign jurisdiction. This summary discusses only the federal income tax consequences of the merger and does not 38 49 discuss the tax consequences of any other transaction that may occur before, after or at the same time as the merger, whether or not any of these transactions are undertaken as part of with the merger. No ruling from the IRS concerning the federal income tax consequences of the merger will be requested. The tax consequences described in this discussion are not binding on the IRS or the courts and contrary positions may be successfully asserted by the IRS or adopted by a court. INDUS RIVER STOCKHOLDERS SHOULD CONSULT THEIR OWN TAX ADVISORS ABOUT THE PARTICULAR TAX CONSEQUENCES TO THEM OF THE MERGER, INCLUDING THE APPLICABILITY AND EFFECT OF ANY FOREIGN, STATE, LOCAL OR OTHER TAX LAWS. CHARACTERIZATION OF THE MERGER FOR FEDERAL INCOME TAX PURPOSES Cabletron and Indus River plan to treat the merger as a tax-free reorganization for federal income tax purposes. This treatment will depend in part on if, and when, Cabletron conducts a spin-off or other disposition of Enterasys, the company to which Cabletron plans to transfer the Indus River stock after the merger, and whether the IRS would attempt to assert that, for federal income tax purposes, a spin-off or other disposition of Enterasys should be combined with the merger. Although Cabletron has announced its desire to establish its four operating subsidiaries, including Enterasys, as independent companies, Cabletron is not obligated to do so and continues to consider several possibilities for Enterasys, including the possibility of retaining Enterasys as a subsidiary of Cabletron. Cabletron might carry out its announced intention to spin off or dispose of Enterasys. If the IRS were to successfully assert that, for federal income tax purposes, this merger should be combined with the spin-off or other disposition of Enterasys, this merger would constitute a taxable purchase and sale of Indus River stock. Federal Income Tax Consequences to Indus River Stockholders Treatment of Merger as a Tax-Free Reorganization. If the merger is treated as a tax-free reorganization, the merger should result in the following federal income tax consequences: - An Indus River stockholder should not recognize gain or loss on the exchange of Indus River stock solely for Cabletron stock. An Indus River stockholder who receives cash proceeds instead of a fractional share interest in Cabletron stock will recognize gain or loss equal to the difference between those proceeds and the tax basis allocated to the fractional share interest. This gain or loss will constitute capital gain or loss if the stockholder's Indus River stock is held as a capital asset at the effective time of the merger. - The aggregate tax basis of the Cabletron stock, including any fractional share of Cabletron stock not actually received and any shares of Cabletron stock held in escrow, received by an Indus River stockholder who exchanges Indus River stock for Cabletron stock will be the same as the stockholder's aggregate tax basis in the Indus River stock surrendered in exchange for Cabletron common stock and Cabletron series C preferred stock. - The holding period of the Cabletron stock received by an Indus River stockholder will include the period during which the shares of Indus River stock surrendered in exchange for Cabletron common stock and Cabletron series C preferred stock were held so long as the Indus River stock is held by the stockholder as a capital asset at the effective time of the merger. - Part of the aggregate shares of Cabletron common stock to be issued in the merger will be held in escrow to satisfy possible indemnification claims. Each former Indus River stockholder who has shares of Cabletron common stock held in escrow should be treated for federal income tax purposes as the owner of the escrow portion of its merger consideration. That stockholder should recognize no gain or loss on the receipt of the Cabletron common stock upon the release to the stockholder of its shares from escrow. However, if the escrow agent pays any of the escrowed shares to Cabletron to indemnify 39 50 Cabletron, each former Indus River stockholder who has shares of Cabletron common stock held in escrow will recognize gain or loss equal to the difference between: - - the fair market value of its portion of the escrowed shares paid to Cabletron; and - - its tax basis in the escrowed shares. Each former Indus River stockholder who has shares of Cabletron common stock held in escrow will increase the tax basis in its remaining Cabletron stock by an amount equal to any indemnification payment. - Indus River stockholders who exercise dissenters' rights and who receive payment for their Indus River stock in cash should recognize gain or loss measured by the difference between the amount of cash received and the stockholder's basis in the shares surrendered. This is true if the payment is neither essentially equivalent to a dividend within the meaning of section 302 of the Internal Revenue Code nor has the effect of a distribution of a dividend within the meaning of section 356(a)(2) of the Internal Revenue Code. A sale of Indus River stock as part of an exercise of dissenters' rights will not be essentially equivalent to a dividend if the stockholder exercising dissenters' rights owns no shares of Cabletron stock or Indus River stock, either actually or constructively within the meaning of section 318 of the Internal Revenue Code, immediately after the merger. If a stockholder's sale for cash of Indus River stock as part of an exercise of dissenters' rights is essentially equivalent to a dividend, then the stockholder may recognize ordinary income for federal income tax purposes in an amount equal to the entire amount of cash received. Treatment of Merger as a Taxable Sale of Indus River Stock. If the merger does not qualify as a tax-free reorganization, an Indus River stockholder will be treated as having sold Indus River stock to Cabletron in exchange for Cabletron stock. Each Indus River stockholder will recognize gain or loss at the effective time of the merger equal to the difference between the stockholder's adjusted tax basis in the Indus River stock and the fair market value of the Cabletron stock received in exchange for the Indus River stock. The gain or loss recognized by Indus River stockholders will be capital gain or loss if the Indus River stock was held as a capital asset in the hands of the stockholder, and will be long-term capital gain or loss if the stockholder has held Indus River stock for more than one year. Long-term gain will in general be subject to a maximum federal income tax rate of 20% for noncorporate taxpayers. An Indus River stockholder's aggregate basis in the Cabletron stock received will equal the fair market value at the effective time of the merger of the Cabletron stock received. The holding period for the Cabletron stock will begin the day after the effective time of the merger. Treatment of Cabletron Series C Preferred Stock. The Cabletron series C preferred stock should be treated for federal income tax purposes as common stock of Cabletron, and holders of Indus River stock should not recognize gain or loss on the exchange of Indus River stock for Cabletron series C preferred stock if the merger is treated as a tax-free reorganization under the Internal Revenue Code. However, because in some circumstances, the Cabletron series C preferred stock is exchangeable for shares of Enterasys and has economic rights that are determined based on the value of Enterasys, it is possible that the IRS might assert that the Cabletron series C preferred stock is nonqualified preferred stock of Cabletron or stock of Enterasys. If the IRS were to prevail in either of these assertions, and even if the merger qualifies as a tax-free reorganization in every other way, holders of Indus River stock would recognize gain at the effective time of the merger equal to the lesser of: - the fair market value of the Cabletron series C preferred stock or - the difference between the fair market value of the Cabletron series C preferred stock and Cabletron common stock received in the merger, and the stockholder's adjusted tax basis in the Indus River stock exchanged for the Cabletron series C preferred stock and Cabletron common stock. If the Cabletron series C preferred stock were determined to be stock of Enterasys and to constitute more than 20% of the aggregate consideration provided in the merger, then the merger would be fully taxable and 40 51 holders of Indus River stock would recognize gain or loss equal to the difference between the fair market value of the Cabletron series C preferred stock and Cabletron common stock received in the merger and their adjusted tax basis in the Indus River stock exchanged for the Cabletron series C preferred stock and the Cabletron common stock. Cabletron and Indus River believe that the Cabletron series C preferred stock should not constitute nonqualified preferred stock or Enterasys stock. However, the IRS has not issued any administrative guidance concerning the scope of the term nonqualified preferred stock or when stock of a parent would be considered stock of the subsidiary and there can be no assurance that this interpretation is correct. If the Cabletron series C preferred stock is treated as stock of Cabletron, its conversion into Cabletron common stock or redemption for Enterasys stock, cash or other property should have the following federal income tax consequences: - Holders of Cabletron series C preferred stock should not recognize any gain or loss on the conversion of their Cabletron series C preferred stock into Cabletron common stock. - Holders of Cabletron series C preferred stock should not recognize any gain or loss on the redemption of their Cabletron series C preferred stock for Enterasys stock, if the redemption is part of Cabletron's distribution of Enterasys stock to the Cabletron stockholders and is governed by section 355 of the Internal Revenue Code. - If the redemption of Cabletron series C preferred stock is not governed by section 355 of the Internal Revenue Code, holders of Cabletron series C preferred stock will have a taxable redemption and should recognize gain or loss on the redemption if the redemption is not essentially equivalent to a dividend within the meaning of section 302 of the Internal Revenue Code, as described above. The amount of gain or loss recognized in a taxable redemption will equal the difference between the cash, if any, and fair market value of other property received as redemption proceeds and the adjusted tax basis in the Cabletron series C preferred stock redeemed. If a stockholder's taxable redemption is essentially equivalent to a dividend, that stockholder may recognize ordinary income in an amount equal to the redemption proceeds, whether or not received in cash. THE PRECEDING DISCUSSION IS INTENDED ONLY AS A SUMMARY OF SIGNIFICANT FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER AND IS NOT A COMPLETE ANALYSIS OR DISCUSSION OF ALL RELEVANT POTENTIAL TAX EFFECTS. INDUS RIVER STOCKHOLDERS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS ABOUT THE SPECIFIC TAX CONSEQUENCES TO THEM OF THE MERGER, INCLUDING TAX RETURN REPORTING REQUIREMENTS AND THE APPLICABILITY AND EFFECT OF FEDERAL, STATE, LOCAL, AND OTHER APPLICABLE TAX LAWS. GOVERNMENT FILINGS Cabletron and Indus River do not believe that any governmental filings in the United States are required for the merger, other than the filing of the registration statement with the Securities and Exchange Commission of which this proxy statement/prospectus is a part. RIGHTS OF STOCKHOLDERS TO APPRAISALS Under the Delaware General Corporation Law, any holder of Indus River stock who does not wish to accept the merger consideration for its shares of Indus River common stock or Indus River preferred stock has the right to dissent from the merger. A stockholder has the right to seek an appraisal of, and to be paid the fair cash value for, its shares of Indus River preferred stock or Indus River common stock, judicially determined, and paid to the stockholder in cash, with a fair rate of interest, if any, only if that stockholder fully complies with the provisions of section 262 of the Delaware General Corporation Law. However, a dissenting Indus River stockholder will not be entitled to receive any cash that represents value arising from the accomplishment or expectation of the merger. A copy of section 262 of the Delaware General Corporation Law is attached as annex B to this proxy statement/prospectus. 41 52 Making sure that you actually perfect your appraisal rights can be complicated. The procedural rules are specific and must be followed precisely. Failure to comply with the procedure may cause a termination of your appraisal rights. The following information is intended as a brief summary of the material provisions of the statutory procedures you must follow to perfect your appraisal right. Please review section 262 for the complete procedure. Indus River will not give you any notice other than what is described in this proxy statement/prospectus and what is required by the Delaware General Corporation Law. APPRAISAL RIGHTS PROCEDURES If you are an Indus River preferred stockholder or an Indus River common stockholder and you wish to exercise your appraisal rights, you must satisfy the provisions of section 262 of the Delaware General Corporation Law. Section 262 requires that: - YOU MUST MAKE A WRITTEN DEMAND FOR APPRAISAL: You must deliver a written demand for appraisal to Indus River before the vote on the merger agreement is taken at the special meeting. This written demand for appraisal must be separate from your proxy card. A vote against the merger agreement alone will not constitute demand for appraisal. - YOU MUST REFRAIN FROM VOTING FOR APPROVAL OF THE MERGER: You must not vote for approval of the merger agreement. If you vote, by proxy or in person, in favor of the merger agreement, this will terminate your right to appraisal. You can also terminate your right to appraisal if you return a signed proxy card and: - fail to vote against approval of the merger; or - fail to note that you are abstaining from voting. If you do either of these two things, then your appraisal rights will be terminated even if you previously filed a written demand for appraisal. - YOU MUST CONTINUOUSLY HOLD YOUR INDUS RIVER SHARES: You must continuously hold your shares of Indus River stock, from the date you make the demand for appraisal through the closing of the merger. If you are the record holder of Indus River stock on the date the written demand for appraisal is made but then transfer the shares before the merger, you will lose any right to appraisal of those shares. You should read the paragraphs below for more details on making a demand for appraisal. A written demand for appraisal of Indus River stock is only effective if it is signed by, or for, the stockholder of record who owns the shares at the time the demand is made. The demand must be signed as the stockholder's name appears on its Indus River preferred stock or common stock certificates. If you are the beneficial owner of Indus River stock, but not the stockholder of record, you must have the stockholder of record sign a demand for appraisal. If you own Indus River stock in a fiduciary capacity, such as a trustee, guardian or custodian, you must disclose the fact that you are signing the demand for appraisal in that capacity. If you own Indus River stock with more than one person, such as in a joint tenancy or tenancy in common, all the owners must sign, or have signed for them, the demand for appraisal. An authorized agent, which could include one or more of the joint owners, may sign the demand for appraisal for a stockholder of record. The agent must expressly disclose who the stockholder of record is and that the agent is signing the demand as that stockholder's agent. If you are a record owner, such as a broker, who holds Indus River stock as a nominee for others, you may exercise a right of appraisal for the shares held for one or more beneficial owners, while not exercising the right for other beneficial owners. You should specify in the written demand the number of shares for which you wish to demand appraisal. If you do not expressly specify the number of shares, Indus River will assume that your written demand covers all the shares of Indus River stock that are in your name. 42 53 If you are an Indus River stockholder who elects to exercise appraisal rights, you should mail or deliver a written demand to: 31 Nagog Park Acton, Massachusetts, 01720 Attention: David P. Gamache It is important that Indus River receive all written demands before the vote concerning the merger agreement is taken at the special meeting. As explained above, this written demand should be signed by, or on behalf of, the stockholder of record. The written demand for appraisal should specify the stockholder's name and mailing address, the number of shares of stock owned, and that the stockholder is demanding appraisal of his shares. If you fail to comply with any of these conditions and the merger becomes effective, you will only be entitled to receive the merger consideration provided in the merger agreement. WRITTEN NOTICE: Within ten days after the closing of the merger, Indus River must give written notice that the merger has become effective to each stockholder who has fully complied with the conditions of section 262. PETITION WITH THE CHANCERY COURT: Within 120 days after the merger, either the surviving corporation or any stockholder who has complied with the conditions of section 262, may file a petition in the Delaware Court of Chancery. This petition should request that the chancery court determine the value of the shares of stock held by all the stockholders who are entitled to appraisal rights. If you intend to exercise your appraisal rights, you should file this petition in the chancery court. Indus River has no intention at this time to file this petition. Because Indus River has no obligation to file this petition, if you do not file this petition within 120 days after the closing, you will lose your rights of appraisal. WITHDRAWAL OF DEMAND: If you change your mind and decide you no longer want appraisal rights, you may withdraw your demand for appraisal rights at any time within 60 days after the closing of the merger. You may also withdraw your demand for appraisal rights after 60 days after the closing of the merger, but only with the written consent of Indus River. If you effectively withdraw your demand for appraisal rights, you will receive the merger consideration provided in the merger agreement. REQUEST FOR APPRAISAL RIGHTS STATEMENT: If you have complied with the conditions of section 262, you are entitled to receive a statement from Indus River. This statement will describe the number of shares that have demanded appraisal rights, and the number of stockholders who own those shares. To receive this statement, you must send a written request to Indus River within 120 days after the merger. After the merger, Indus River has 10 days after receiving a request to mail you the statement. CHANCERY COURT PROCEDURES: If you properly file a petition for appraisal in the chancery court and deliver a copy to Indus River, Indus River will then have 20 days to provide the chancery court with a list of the names and addresses of all stockholders who have demanded appraisal rights and have not reached an agreement with Indus River concerning the value of their shares. The chancery court will then send notice to all the stockholders who have demanded appraisal rights. If the chancery court thinks it is appropriate, the chancery court has the power to conduct a hearing to determine whether the stockholders have fully complied with section 262 and whether they are entitled to appraisal rights under that section. The chancery court may also require you to submit your stock certificates to the Registry in Chancery so that it can note on the certificates that an appraisal proceeding is pending. If you do not follow the chancery court's directions, you may be dismissed from the proceeding. APPRAISAL OF SHARES: After the chancery court determines which stockholders are entitled to appraisal rights, the chancery court will appraise the shares of stock. To determine the fair value of the shares, the chancery court will consider all relevant factors except for any appreciation or depreciation due to the anticipation or accomplishment of the merger. After the chancery court determines the fair value of the shares, it will direct Indus River to pay that value to the stockholders who are entitled to appraisal rights. The chancery court can also direct Indus River to pay interest, simple or compound, on that value if the chancery court determines that interest is appropriate. To receive payment for your shares, you must then surrender your stock certificates to Indus River. 43 54 The chancery court could determine that the fair value of shares of stock is more than, the same as, or less than the merger consideration. If you demand appraisal rights, you could receive less consideration than you would under the merger agreement. COSTS AND EXPENSES OF APPRAISAL PROCEEDING: The costs of the appraisal proceeding may be assessed against Indus River and the stockholders participating in the appraisal proceeding, in whatever manner the chancery court believes is equitable under the circumstances. You may request that the chancery court determine the amount of interest, if any, Indus River should pay on the value of stock owned by stockholders entitled to the payment of interest. You may also request that the chancery court allocate the expenses of the appraisal action incurred by any stockholder pro rata against the value of all the shares entitled to appraisal. LOSS OF STOCKHOLDER'S RIGHTS: If you demand appraisal rights, after the closing of the merger you will not be entitled: - to vote the shares of stock for which you have demanded appraisal rights for any purpose; - to receive payment of dividends or any other distribution on the shares of stock for which you have demanded appraisal, except for dividends or distributions, if any, that are payable to holders of record as of a record date before the effective time of the merger; or - to receive the payment of the consideration provided for in the merger agreement, unless you properly withdraw your demand for appraisal. If no petition for an appraisal is filed within 120 days after the closing of the merger, your right to an appraisal will cease. You may withdraw your demand for appraisal and accept the merger consideration by delivering to Indus River a written withdrawal of your demand, except that: - any attempt to withdraw made more than 60 days after the closing of the merger will require the written approval of Indus River; and - an appraisal proceeding in the chancery court cannot be dismissed unless the chancery court approves.

AMENDMENT'S TO INDUS RIVER'S BY-LAWS The by-laws of Acton Acquisition Co., as in effect immediately before the merger, will be the by-laws of the surviving corporation after the merger. INDEMNIFICATION AND ESCROW AGREEMENT Escrow Fund and Indemnification. The merger agreement provides that 10% of the shares of Cabletron common stock to be issued in the merger to holders of Indus River preferred stock and the founders of Indus River will be placed in escrow with 51 62 an escrow agent as soon as possible after the merger is completed. Those shares of Cabletron common stock held in escrow will be subject to an escrow agreement among State Street Bank and Trust Company, as escrow agent, Stephen J. Ricci, as stockholder representative, and Cabletron, which is attached as annex C to this proxy statement/prospectus. The number of shares of Cabletron common stock to be received by those Indus River stockholders will be reduced by 10% of the shares of Cabletron common stock the stockholders would otherwise be entitled to receive. The escrow account will be the sole and exclusive source available to compensate Cabletron for the indemnification obligations of each Indus River stockholder under the merger agreement, other than for any claim of fraud, intentional misrepresentation or other willful conduct. Indus River has agreed to indemnify Cabletron, the surviving corporation and their subsidiaries and affiliates from and against all claims, damages, costs and expenses, including reasonable legal fees, because of breaches by Indus River of the merger agreement. Cabletron may not seek indemnification until the aggregate amount of all damages for which Cabletron is seeking indemnification is at least $300,000. Cabletron may then seek indemnification for all of its damages. If any claim is required to be paid from the escrow fund containing the shares of Cabletron common stock, the value of the shares of Cabletron common stock held in the escrow fund will be determined based on the average of the closing prices of Cabletron common stock as reported in the Wall Street Journal for the 30 trading days before the date of determination. The escrow fund for the Cabletron common stock will terminate on the first anniversary of the closing date of the merger. The remaining Cabletron common stock in the escrow fund will then be distributed by the escrow agent to the stockholders on whose behalf the shares are being held based on each stockholder's percentage of the escrow fund. Any escrowed shares against which Cabletron has made a claim before the first anniversary of the closing date of the merger that has not been resolved, will not be released until the claim is resolved. The merger agreement provides that Stephen J. Ricci has been appointed as a representative for the Indus River stockholders whose shares are being held in escrow to take all actions necessary or appropriate in his judgment for the accomplishment of the terms of the merger agreement. The holders of a majority in interest of the shares of Cabletron common stock held in the escrow fund may replace the stockholder representative upon at least 10 days' prior written notice to Cabletron. The stockholder representative will not be required to provide a bond and will not receive any compensation for his services. Notices of communications to or from the stockholder representative will constitute notice to or from each Indus River stockholder who has Cabletron common stock deposited in the escrow fund. If Mr. Ricci is no longer able or willing to serve as the stockholder representative, a new stockholder representative will be chosen by stockholders holding a majority of the shares of Cabletron common stock being held in escrow. The stockholder representative will not be liable for any act done or omitted in his capacity as stockholder representative while acting in good faith and in the exercise of reasonable judgment, and any act done or omitted based on the advice of counsel will be conclusive evidence of good faith. Those Indus River stockholders who have executed a stockholder agreement, and whose shares of Cabletron common stock are being held in the escrow account, have agreed to individually indemnify the stockholder representative and hold him harmless against any loss, liability or expense incurred without gross negligence or bad faith on his part and arising out of the acceptance or administration of his duties. Any decision, act, consent or instruction of the stockholder representative will constitute a decision of all Indus River stockholders whose shares of Cabletron common stock are being held in the escrow account and will be final, binding and conclusive upon each stockholder, and the escrow agent and Cabletron may rely upon any decision, act, consent or instruction of the stockholder representative. The escrow agent and Cabletron are relieved from any liability to any person for acts done by them based on a decision, act, consent or instruction of the stockholder representative. Escrow of Shares of Cabletron Series C Preferred Stock. The merger agreement also provides that all of the shares of Cabletron series C preferred stock to be issued in the merger will be placed in a separate escrow account with an escrow agent after the merger is 52 63 completed. The shares of Cabletron series C preferred stock will be subject to the provisions of the escrow agreement, the form of which is attached as annex C to this proxy statement/prospectus. The shares of Cabletron series C preferred stock will be held in escrow only to facilitate any conversion or redemption occurring within 24 months of the date of issuance of the Cabletron series C preferred stock. The shares will remain in the escrow account until any conversion or redemption of the Cabletron series C preferred stock, after which the stockholders on whose behalf the shares are being held will receive; - shares of Cabletron common stock issued upon conversion of Cabletron series C preferred stock; or - shares of Enterasys common stock or other securities issued upon redemption of Cabletron series C preferred stock. If no redemption or conversion occurs within 24 months of the date of issuance of the Cabletron series C preferred stock, the shares held in escrow will be distributed by the escrow agent to the stockholders on whose behalf the shares are being held on or before the 30-month anniversary of the date of issuance of the Cabletron series C preferred stock. The escrow agreement states that the shares of Cabletron series C preferred stock may not be transferred except under the laws of descent and distribution or to the partners or equity holders of any stockholder which is an entity. 53 64 STOCK PRICES AND DIVIDENDS Cabletron common stock is listed for trading on the New York Stock Exchange under the trading symbol CS.

Because the market price of Cabletron common stock fluctuates, the market value of the shares of Cabletron common stock that Indus River stockholders will receive in the merger, may increase or decrease after the receipt of the shares. Because there is no established trading market for the Cabletron series C preferred stock, the market value of the shares of Cabletron series C preferred stock that Indus River stockholders will receive in the merger may be difficult to determine and the market value, if determinable, may increase or decrease after the receipt of the shares.

Each holder of a Cabletron series A and Cabletron series B preferred stock will be entitled to the number of votes for each share of Cabletron series A and Cabletron series B preferred stock it holds equal to the number of shares of Cabletron common stock into which each share of Cabletron series A or Cabletron series B preferred stock, may be converted on the record date for holders entitled to participate in the vote. Any holders of Cabletron series A and Cabletron series B preferred stock will have the following additional voting rights: - the holders of a majority of the then outstanding shares of Cabletron series A and Cabletron series B preferred stock must approve any amendment or restatement of Cabletron's certificate of incorporation or of the certificate of designation for the Cabletron series A and Cabletron series B preferred stock that adversely affects the powers, preferences and rights of the Cabletron series A and Cabletron series B preferred stock; - the holders of a majority of the then outstanding shares of Cabletron series A preferred stock must approve any amendment or restatement of Cabletron's certificate of incorporation or of the certificate of designation for the Cabletron series A and Cabletron series B preferred stock that adversely affects the powers, preferences and rights of the Cabletron series A preferred stock; and - the holders of a majority of the then outstanding shares of Cabletron series B preferred stock must approve any amendment or restatement of Cabletron's certificate of incorporation or of the certificate of designation for the Cabletron series A and Cabletron series B preferred stock that adversely affects the powers, preferences and rights of the Cabletron series B preferred stock. CONVERSION RIGHTS. Each holder of Cabletron series A and Cabletron series B preferred stock may, at its option, convert any of its shares of Cabletron series A and Cabletron series B preferred stock at any time into shares of Cabletron common stock. Cabletron series A and Cabletron series B preferred stock can be converted into Cabletron common stock at an initial rate obtained by multiplying the applicable conversion rate by the number of shares of Cabletron series A and Cabletron series B preferred stock held by the holder that are being converted by the holder. For each share of Cabletron series A and Cabletron series B preferred stock, the applicable conversion rate is determined by dividing $1,000, plus accrued and unpaid dividends, by the applicable conversion value.

The applicable conversion value will be adjusted for stock splits, stock dividends, recapitalizations and other similar events. If Cabletron is unable to redeem the Cabletron series A and Cabletron series B preferred stock as Cabletron is required to do, then the applicable conversion value will be adjusted to equal the product of 90% multiplied by the market price of Cabletron common stock on the date specified for redemption or on the date the holders of Cabletron series A and Cabletron series B preferred stock receive notice that Cabletron cannot conduct a redemption. Generally, the market price of the Cabletron common stock will be equal to the last sale price of the stock on the New York Stock Exchange. Before any corporate change, Cabletron will make appropriate provisions to ensure that each holder of Cabletron series A and Cabletron series B preferred stock will have the right to receive, upon conversion of the holder's preferred stock into Cabletron common stock, the stock, securities or assets that the holder would have been entitled to receive in the corporate change if that holder had converted its preferred stock into Cabletron common stock before the record date for the corporate change. Cabletron will not engage in any corporate change unless, before the corporate change, the successor corporation or the purchasing corporation assumes in writing the obligation to deliver to each holder of Cabletron series A and Cabletron series B preferred stock the shares of stock, securities or assets that the holder is entitled to receive as described above.

Each share of Cabletron series C preferred stock will be entitled to receive dividends at a rate per share equal to the product of the dividend declared on each share of Cabletron common stock and the applicable conversion rate. The applicable conversion rate is currently 10, adjusted for stock splits, stock dividends, recapitalizations and other similar events. The applicable conversion rate will be adjusted in the manner described below in "-- Conversion Rights." The holders of Cabletron series C preferred stock will not be entitled to participate in any extraordinary distribution.

The Cabletron series C preferred stock will be convertible into Cabletron common stock at the option of the holder at any time following the earliest to occur of: - an Enterasys spinoff that occurs on or after the first anniversary of the date the Cabletron series C preferred stock is issued; - an Enterasys transaction at any time; and - the second anniversary of the date the Cabletron series C preferred stock is issued. If Cabletron establishes a record date for an Enterasys spinoff before the first anniversary of the date the Cabletron series C preferred stock is issued, and that spin-off is to be completed before the first anniversary, then the Cabletron series C preferred stock will be convertible into Cabletron common stock at the option of the holder immediately before the Enterasys spinoff. Cabletron may never conduct an Enterasys spinoff or an Enterasys transaction. It is possible that holders of Cabletron series C preferred stock will not be able to convert their shares of Cabletron series C preferred stock until the second anniversary of the date the Cabletron series C preferred stock is issued. A holder of Cabletron series C preferred stock that elects to convert its shares of Cabletron series C preferred stock into Cabletron common stock will receive the number of shares of Cabletron common stock equal to the number of shares of Cabletron series C preferred stock held by that holder multiplied by the applicable conversion rate. The Applicable Conversion Rate. The applicable conversion rate will initially be 10. The applicable conversion rate will be adjusted for a number of circumstances as discussed below. Other than adjustments to the applicable conversion rate for events such as stock splits, stock dividends and combinations discussed under "-- Adjustments to the Applicable Conversion Rate -- Stock Dividends, Stock Splits, Combinations," the applicable conversion rate will never be adjusted to exceed 65. The applicable conversion rate will usually be determined based on the value of the stock of Cabletron's subsidiary, Enterasys. The value will be determined in the manner described below. ADJUSTMENTS TO THE APPLICABLE CONVERSION RATE -- STOCK DIVIDENDS, STOCK SPLITS, COMBINATIONS. If there is: - a subdivision of the outstanding shares of Cabletron common stock into a greater number of shares of Cabletron common stock, such as through a stock split, stock dividend or recapitalization; or - a combination of the outstanding shares of Cabletron common stock into a smaller number of shares of Cabletron common stock, such as through a reverse stock split, then the applicable conversion rate will be adjusted to reflect the stock dividend, stock split or recapitalization. ENTERASYS SPINOFF WITHIN ONE YEAR OF THE DATE OF ISSUANCE OF THE CABLETRON SERIES C PREFERRED STOCK. If Cabletron establishes a record date for an Enterasys spinoff before the first anniversary of the date the Cabletron series C preferred stock is issued, and that spin-off is to be completed before the first anniversary, then the Cabletron series C preferred stock will be convertible into Cabletron common stock at the option of the holder immediately before the Enterasys spinoff. The applicable conversion rate will be permanently adjusted to equal the quotient obtained from the following formula: applicable conversion rate E X P(E) = ------------- 50,000 X P(C)
In this formula: - E is equal to the number of Enterasys shares equal to 1% of the fully-diluted stock of Enterasys, determined as of the day the merger closes, adjusted for stock splits, stock dividends, recapitalizations, extraordinary distributions and other similar events affecting the stock of Enterasys; - P(E) is the market price of the Enterasys stock, determined as of the close of business on the applicable record date; and 60 71 - P(C) is the market price of Cabletron common stock as of the close of business on that record date. For an Enterasys spinoff, the market price of Enterasys stock will usually be equal to the last sale price of the stock on the New York Stock Exchange on the applicable trading day. For an Enterasys transaction, the market price of Enterasys stock will usually be the price at which Enterasys stock is sold in the Enterasys transaction. Generally, the market price of the Cabletron common stock will be equal to the last sale price of the stock on the New York Stock Exchange on the applicable trading day.

If Cabletron conducts an Enterasys spinoff after the first anniversary of the date the Cabletron series C preferred stock is issued and before the second anniversary of that date, or if Cabletron conducts an Enterasys transaction before the second anniversary of the date the Cabletron series C preferred stock is issued, then the Cabletron series C preferred stock will be convertible into Cabletron common stock at the option of the holder after the earlier to occur of that event. After that event, the applicable conversion rate will be permanently adjusted to equal the quotient obtained from the following formula: Applicable Conversion Rate = .9 X E X P(E) ------------- 50,000 X P(C)
In this formula: - E is equal to the number of Enterasys shares equal to 1% of the fully-diluted stock of Enterasys, determined as of the day the merger closes, adjusted for stock splits, stock dividends, recapitalizations, extraordinary distributions and other similar events affecting the stock of Enterasys; - P(E) is the market price of the Enterasys stock distributed in the Enterasys spinoff or the Enterasys transaction determined as of the close of business on the first trading day after the Enterasys spinoff or Enterasys transaction; and - P(C) is the market price of Cabletron common stock as of the close of business on that trading day. For an Enterasys spinoff, the market price of Enterasys stock will usually be equal to the last sale price of the stock on the New York Stock Exchange on the applicable trading day. For an Enterasys transaction, the market price of Enterasys stock will usually be the price at which Enterasys stock is sold in the Enterasys transaction. The market price of the Cabletron common stock will usually be equal to the last sale price of the stock on the New York Stock Exchange on the applicable trading day.

If Cabletron does not conduct either an Enterasys spinoff or an Enterasys transaction before the second anniversary of the date the Cabletron series C preferred stock is issued, then the Cabletron series C preferred stock will be convertible into Cabletron common stock at the option of the holder immediately after the second anniversary of the date the Cabletron series C preferred stock is issued. After this second anniversary, the applicable conversion rate will be permanently adjusted to equal the quotient obtained from the following formula: applicable conversion rate = E X P(E) ------------- 50,000 X P(C)
In this formula: - E is equal to the number of Enterasys shares equal to 1% of the fully-diluted stock of Enterasys, determined as of the day the merger closes, adjusted for stock splits, stock dividends, recapitalizations, extraordinary distributions and other similar events affecting the stock of Enterasys; - P(E) is the market price of the Enterasys stock, determined as of the second anniversary of the date the Cabletron series C preferred stock is issued; and - P(C) is the market price of Cabletron common stock as of the close of business on that day. 61 72 Cabletron's board of directors will determine the market price of Enterasys stock. If the holders of a majority of the outstanding shares of Cabletron series C preferred stock object to the determination by Cabletron's board, then Cabletron will hire an investment banking firm to conduct an appraisal of the fair value of Enterasys stock. The market price of the Cabletron common stock will usually be equal to the last sale price of the stock on the New York Stock Exchange on the second anniversary of the date the Cabletron series C preferred stock is issued. Corporate Change. Before any corporate change, Cabletron will make sure that each holder of Cabletron series C preferred stock will receive, upon conversion of the holder's preferred stock into Cabletron common stock, the stock, securities or assets that the holder would have been entitled to receive in the corporate change if that holder had converted its preferred stock into Cabletron common stock before the record date for the corporate change.

CORPORATE CHANGE BEFORE ENTERASYS SPINOFF, ENTERASYS TRANSACTION OR THE SECOND ANNIVERSARY OF THE DATE OF ISSUANCE OF THE CABLETRON SERIES C PREFERRED STOCK. If a corporate change were to occur before the first to occur of an Enterasys spinoff, an Enterasys transaction and the second anniversary of the date the Cabletron series C preferred stock is issued, then the applicable conversion rate will be adjusted to equal the greater of: - 10, adjusted for stock splits, stock dividends and combinations, as described above under "-- Adjustments to the Applicable Conversion Rate -- Stock Dividends, Stock Splits, Combinations;" and - the quotient obtained from the following formula: applicable conversion rate = E X P(E) ------------- 50,000 X P(C)
In this formula: - E is equal to the number of Enterasys shares equal to 1% of the fully-diluted stock of Enterasys, determined as of the day the merger closes, adjusted for stock splits, stock dividends, recapitalizations, extraordinary distributions and other similar events affecting the stock of Enterasys; - P(E) is the market price of the Enterasys stock, determined as of the effective date of the corporate change; and - P(C) is the market price of Cabletron common stock as of the close of business on that day.

The market price of the Cabletron common stock will usually be equal to the price at which Cabletron common stock is sold in the corporate change. CORPORATE CHANGE AFTER AN ENTERASYS SPINOFF, ENTERASYS TRANSACTION OR THE SECOND ANNIVERSARY OF THE DATE OF ISSUANCE OF THE CABLETRON SERIES C PREFERRED STOCK. If a corporate change were to occur after the first to occur of an Enterasys spinoff, an Enterasys transaction and the second anniversary of the date the Cabletron series C preferred stock is issued, then the applicable conversion rate will be adjusted in the manner described above under "-- Enterasys spinoff or Enterasys transaction within Two Years of the Date of 62 73 Issuance of the Cabletron Series C Preferred Stock" or "-- No Enterasys Spinoff or Enterasys Transaction within Two Years of the Date of Issuance of the Cabletron Series C Preferred Stock."

If the conversion notice does not specify a date, then the conversion date will be considered to be the date on which Cabletron or Cabletron's agent receives the conversion notice.

If any holder of Cabletron series C preferred stock elects to exercise its conversion rights, it will receive the number of fully paid and non assessable shares of Cabletron common stock, determined by using the formula in the certificate of designation for the Cabletron series C preferred stock, and that is described above under "Description of Cabletron Capital Stock -- Preferred Stock -- series C Preferred Stock -- Conversion Rights."

Holders of Indus River common stock have no right to convert their shares into any other securities. Subject to the terms, conditions, limitations and adjustments stated in Indus River's certificate of incorporation, the holders of each series of Indus River preferred stock have the right, at their option, to convert any shares of preferred stock into the number of fully paid and nonassessable shares of Indus River common stock, determined by using the formula in the Indus River certificate of incorporation.

If the redemption right is exercised in an Enterasys spinoff, the redemption price will be paid in shares of Enterasys stock at the beginning of the spin-off. If the redemption right is exercised in an Enterasys transaction, the redemption price will be paid in securities or assets of the surviving corporation immediately after the transaction. The redemption rights for the Cabletron series C preferred stock will terminate immediately after the first to occur of: - an Enterasys spinoff; - an Enterasys transaction; and - the second anniversary of the date of issuance of the series C preferred stock.

The portions of Indus River preferred stock to be redeemed on each redemption date will be: - 33 1/3% on June 30, 2004 - 50% of the remaining outstanding shares on June 30, 2005 and - 100% all remaining outstanding shares on June 30, 2006. If the funds of Indus River legally available for redemption of Indus River preferred stock on any mandatory redemption date are not sufficient to redeem the shares of Indus River preferred stock required to be redeemed, the funds that are legally available for redemption will be used to redeem the maximum possible number of shares of Indus River preferred stock on a pro rata basis. If, at any time, additional funds of Indus River become legally available for redemption of Indus River preferred stock, those funds will be used, at the end of the next fiscal quarter, to redeem, the balance of the shares that are subject to the right of redemption. Indus River's certificate of incorporation also provides for a special mandatory conversion of the Indus River series A preferred stock, Indus River series B preferred stock and Indus River series D preferred stock if the holders of that preferred stock do not exercise rights to participate in a subsequent equity financing.

The Cabletron certificate of incorporation defines a related person as any individual, corporation, partnership, unincorporated association or other person or entity that, with its affiliates and associates, beneficially owns, or during the three-year period immediately before the date on which it is sought to be determined whether that person is a related person, owned 5% or more of the outstanding shares of voting stock of any class of Cabletron's securities. The term related person does not include: - Cabletron or any direct or indirect majority-owned subsidiary of Cabletron; - any person that, with its affiliates and associates, beneficially owned in the aggregate 5% or more of the outstanding shares of voting stock of any class of Cabletron stock at the time of Cabletron's initial public offering, any affiliate or associate of that person or any person that acquired those shares from that person by gift, inheritance or in a transaction in which no consideration was exchanged; or - any person whose ownership of shares in excess of the 5% limitation stated above is the result of action taken solely by Cabletron. However, a person will be a related person if afterwards that person acquires additional shares of voting stock of Cabletron. A person who does this will not be a related person if the additional shares were acquired because of corporate action not caused, directly or indirectly by that person. For the purpose of determining whether a person is a related person, the voting stock of Cabletron considered outstanding shall include stock beneficially owned by the person. However, the voting stock outstanding will not include any other unissued 76 87 stock of Cabletron which may be issuable under any agreement, arrangement or understanding, or upon exercise of conversion rights, warrants or options, or other similar securities. INDUS RIVER. Indus River is a Delaware corporation and is subject to the provisions of the Delaware General Corporation Law described above. The Indus River's certificate of incorporation also provides that if any shares of Indus River preferred stock are outstanding, Indus River may not consolidate or merge with or into any other entity without the approval of the holders of at least two-thirds of the then outstanding shares of Indus River preferred stock, voting or consenting as a single class. ANTI-TAKEOVER PROVISIONS The Delaware General Corporation Law prohibits some transactions between a Delaware corporation and an interested stockholder, which is defined as a person that is directly or indirectly a beneficial owner of 15% or more of the voting power of the outstanding voting stock of a Delaware corporation and affiliates and associates of that person. This provision prohibits some business combinations, which is defined broadly to include mergers, consolidations, sales or other dispositions of assets having an aggregate value in excess of 10% of the consolidated assets of the corporation, and other transactions, between an interested stockholder and a corporation for a period of three years after the date the interested stockholder acquired its stock. However, the prohibition does not apply if either: - the business combination is approved by the corporation's board of directors before the date the interested stockholder acquired its shares; - the interested stockholder acquired at least 85% of the voting stock of the corporation, excluding shares held by directors of the corporation who are also officers and shares held under employee stock plans, in the transaction in which it became an interested stockholder; or - the business combination is approved by a majority of the board of directors and the affirmative vote of two-thirds of the votes entitled to be cast by disinterested stockholders at an annual or special meeting. This law applies automatically to a Delaware corporation unless its certificate of incorporation or bylaws explicitly state that the law will not apply, or if the corporation has less than 2,000 stockholders of record and does not have voting stock listed on a national securities exchange or listed for quotation with a registered national securities association. CABLETRON. Neither the Cabletron certificate of incorporation nor the Cabletron by-laws exempts Cabletron from the provision of the Delaware General Corporation Law limiting transactions with interested stockholders. INDUS RIVER. Indus River is also a Delaware corporation and is subject to the same provisions of the Delaware General Corporation Law. Neither the Indus River certificate of incorporation nor the Indus River by-laws exempts Indus River from the provision of the Delaware General Corporation Law limiting transactions with interested stockholders. STOCKHOLDER DERIVATIVE SUITS Under the Delaware General Corporation Law, a stockholder may bring a derivative action on behalf of the corporation only if the stockholder was a stockholder of the corporation at the time of the transaction in question or if he obtained his stock by operation of law. A stockholder must also first make demand on the corporation that it bring suit and have that demand be refused, unless it is shown that the demand would have been futile. 77 88 INFORMATION CONCERNING INDUS RIVER SECURITY OWNERSHIP OF DIRECTORS, EXECUTIVE OFFICERS AND PRINCIPAL STOCKHOLDERS OF INDUS RIVER The following table provides information about the number of shares of Indus River stock that were beneficially owned as of November 30, 2000 by: - each person that beneficially owns more than 5% of the outstanding shares of Indus River common stock and preferred stock; - each director of Indus River; - Indus River's chief executive officer; - the four other most highly compensated Indus River executive officers who received annual compensation in excess of $100,000, collectively referred to below as the executive officers; and - all Indus River executive officers and directors as a group.

SECTION 1.3 Effect of the Merger. At the Effective Time, the effect of the Merger shall be as provided in this Agreement, the Certificate of Merger and the applicable provisions of the DGCL. Without limiting the generality of the foregoing, and subject thereto, at the Effective Time all the property, rights, privileges, powers and franchises of the Company and Merger Sub shall vest in the Surviving Corporation, and all debts, liabilities and duties of the Company and Merger Sub shall become the debts, liabilities and duties of the Surviving Corporation. SECTION 1.4 Charter; By-Laws. (a) Charter. Unless otherwise determined by the Parent prior to the Effective Time, at the Effective Time, the Certificate of Incorporation of the Surviving Corporation, as in effect immediately prior to the Effective Time, shall be amended and restated to read as did the Certificate of Incorporation of Merger Sub immediately prior to the Effective Time, except that the name of the Surviving Corporation will remain unchanged. (b) By-Laws. Unless otherwise determined by the Parent prior to the Effective Time, at the Effective Time, the By-Laws of the Surviving Corporation, as in effect immediately prior to the Effective Time, shall be amended and restated to read as did the By-Laws of Merger Sub immediately prior to the Effective Time, except that the name of the Surviving Corporation shall remain unchanged.

A-2 100 SECTION 1.6 Effect on Capital Stock. (a) General. Parent will issue 4,000,000 shares of common stock, $.01 par value ("PARENT COMMON STOCK") and 50,000 shares of Series C Participating Convertible Preferred Stock, $1.00 par value (the "PARENT PREFERRED STOCK," and together with the Parent Common Stock, the "PARENT SHARES"), in connection with the acquisition by Parent of the Total Company Outstanding Shares. The total number of Parent Shares shall be issuable in respect of the Total Company Outstanding Shares and, except as provided herein, no adjustment shall be made in the number of Parent Shares issued at the Closing or in the number of Parent Shares issuable upon exercise of Options, including, without limitation, as a result of (x) any increase or decrease in the market price of Parent Common Stock prior to the Effective Time, or (y) any cash proceeds received by the Company from the date hereof to the Closing Date pursuant to the exercise of Options or pursuant to the exercise of any other rights to acquire any capital stock of the Company. (b) Conversion of Securities. (i) Liquidation Preference Payments. Each Company Preferred Share issued and outstanding immediately prior to the Effective Time (excluding any Company Preferred Shares to be canceled pursuant to Section 1.6(d)) shall be entitled to receive the liquidation preference for such Preferred Share, as provided in the Company's Certificate of Incorporation (each, a "LIQUIDATION PREFERENCE PAYMENT," and collectively, the "LIQUIDATION PREFERENCE PAYMENTS"). The Liquidation Preference Payment for each share of Company Preferred Stock shall be payable in a number of shares of (i) Parent Common Stock equal to that share's portion of the aggregate of the Liquidation Preference Payments for that share's series of Company Preferred Stock multiplied by the Common Exchange Ratio and (ii) Parent Preferred Stock equal to that share's portion of the aggregate of the Liquidation Preference Payments for that share's series of Company Preferred Stock multiplied by the Preferred Exchange Ratio, as described below. (A) For each series of the Company Preferred Stock: (1) the Preferred Exchange Ratio for that series equals the Preferred Liquidation Shares for that series divided by the aggregate of the Liquidation Preference Payments for that series; (2) the Preferred Liquidation Shares for that series equals 50,000 multiplied by the quotient of (x) the aggregate of the Liquidation Preference Payments for that series divided by (y) the Total Fair Market Value (as defined herein). (3) the Common Exchange Ratio for that series equals the Common Liquidation Shares for that series divided by the aggregate of the Liquidation Preference Payments for that series; and (4) the Common Liquidation Shares for that series equals the number of shares of Parent Common Stock issuable at Closing pursuant to Section 1.6(a) and reserved at Closing for issuance upon exercise of the Options (excluding Options granted under the Stock Option Plan as contemplated by Sections 4.1(b) and 6.2(h) hereof) multiplied by the quotient of (i) the aggregate of the Liquidation Preference Payments for that series divided by (ii) Total Fair Market Value. (B) For purposes of this Agreement, (1) "TOTAL FAIR MARKET VALUE" equals the sum of (x) the Parent Preferred Stock Fair Market Value (as defined herein) and (y) the Parent Common Stock Fair Market Value (as defined herein); (2) "PARENT PREFERRED STOCK FAIR MARKET VALUE" equals the product of 50,000 multiplied by the fair market value per share of Parent Preferred Stock as determined by an appraisal conducted by Adams, Harkness & Hill, Inc. (or an another appraiser designated by the Company) as of the fifth trading day prior to the Closing Date; A-3 101 (3) "PARENT COMMON STOCK FAIR MARKET VALUE" equals the product of the number of shares of Parent Common Stock issuable at Closing pursuant to Section 1.6(a) and reserved at Closing for issuance upon exercise of the Options (excluding Options granted under the Stock Option Plan as contemplated by Sections 4.1(b) and 6.2(h) hereof) multiplied by the average of the closing price of Parent Common Stock (as reported on the New York Stock Exchange composite tape) for the ten (10) trading days ending on and including the fifth trading day prior to the Closing Date (such average, the "Average Common Price"); (4) "AGGREGATE PREFERRED LIQUIDATION SHARES" is the sum of the Preferred Liquidation Shares for all series of Company Preferred Stock; and (5) "AGGREGATE COMMON LIQUIDATION SHARES" is the sum of the Common Liquidation Shares for all series of Company Preferred Stock. (ii) Additional Merger Consideration. Each Share issued and outstanding immediately prior to the Effective Time (excluding any Shares to be canceled pursuant to Section 1.6(c)) shall be converted, subject to Section 1.6(g), into the right to receive a pro rata portion of the Additional Merger Consideration. The "ADDITIONAL MERGER CONSIDERATION" is the payment to the holders of shares of Company Common Stock (treating the Company Preferred Stock on an as-converted basis (as provided in the Company's Certificate of Incorporation)) of shares of Parent Common Stock and shares of Parent Preferred Stock as follows: Each holder of Shares shall be entitled to receive (A) shares of Parent Preferred Stock equal to the product of the number of Shares held by such holder and the Additional Preferred Exchange Ratio and (B) shares of parent Common Stock equal to the product of the number of Shares held by such holder and the Additional Common Exchange Ratio. The "ADDITIONAL PREFERRED EXCHANGE RATIO" equals (1) 50,000 minus the Aggregate Preferred Liquidation Shares divided by (2) the Total Company Outstanding Shares. The "ADDITIONAL COMMON EXCHANGE RATIO" equals (1) the number of shares Parent Common Stock issuable at Closing pursuant to Section 1.6(a) and reserved at Closing for issuance upon exercise of the Options (excluding Options granted under the Stock Option Plan as contemplated by Sections 4.1(b) and 6.2(h) hereof) minus the Aggregate Common Liquidation Shares divided by (2) the Total Company Outstanding Shares. (c) Stock Options. (i) The employees of the Company have been granted options (each, an "OPTION") to purchase Company Common Stock. At the Effective Time, by virtue of the Merger and without any further action on the part of the holders thereof, each Option shall be assumed by Parent, and shall constitute an option to acquire, on the same terms and conditions as were applicable under the Company's Stock Incentive Program (the "STOCK OPTION PLAN") prior to the Effective Time: (A) the number (rounded down to the nearest whole number) of shares of Parent Common Stock equal to the product of (1) the number of shares of Company Common Stock issuable upon the exercise of such Option immediately prior to the Effective Time (not taking into account whether or not such Option was in fact exercisable, but excluding any Company Common Stock issued prior to the Effective Time pursuant to such Option), multiplied by (2) the Additional Common Exchange Ratio, at a price per share (rounded up to the next highest cent) equal to the Common Exercise Price and (B) the number (rounded down to the nearest whole number) of shares of Parent Preferred Stock equal to the product of the number of shares of Company Common Stock issuable upon the exercise of such Option immediately prior to the Effective Time (not taking onto account whether or not such Option was in fact exercisable, but excluding any Company Common Stock issued prior to the Effective Time pursuant to such Option) and the Additional Preferred Exchange Ratio, at a price per share (rounded up to the next highest cent) equal to the Preferred Exercise Price. A-4 102 The "COMMON EXERCISE PRICE" equals the product of (A) the exercise price per share of the shares of Company Common Stock issuable upon exercise of such Option immediately prior to the Effective Time divided by the Additional Common Exchange Ratio multiplied by (B) Parent Common Stock Fair Market Value divided by Total Fair Market Value. The "PREFERRED EXCHANGE PRICE" equals the product of (A) the exercise price per share of the shares of Company Common Stock issuable upon exercise of such Option immediately prior to the Effective Time divided by the Additional Preferred Exchange Ratio multiplied by (B) the Parent Preferred Stock Fair Market Value divided by Total Fair Market Value. (ii) Conversion of Securities. Parent shall take all corporate action necessary to reserve for issuance a sufficient number of Parent Shares for delivery pursuant to the terms set forth in this Section 1.6(c). (iii) Subject to any applicable limitations under the Securities Act of 1933, as amended (the "SECURITIES ACT"), Parent shall file a Registration Statement on Form S-8 (or any successor form), effective as of the Effective Time, with respect to the Parent Shares issuable upon exercise of the Options (including those additional Options to be granted under the Stock Option Plan as contemplated by Section 4.1(b) and 6.2(h) hereof), and the Parent shall use all reasonable efforts to maintain the effectiveness of such registration statement (and maintain the current status of the prospectus or prospectuses relating thereto) for so long as such Options shall remain outstanding. (iv) Parent shall cause the shares of Parent Common Stock issued pursuant to the Merger and the shares of Parent Common Stock registered on the Form S-8 described above to be approved for listing, upon official notice of issuance, on the New York Stock Exchange. (d) Cancellation. Each Share, if any, held in the treasury of the Company immediately prior to the Effective Time shall by virtue of the Merger and without any action on the part of the holder thereof, shall cease to be outstanding, be canceled and retired without payment of any consideration therefor and cease to exist. (e) Capital Stock of Merger Sub. Each share of common stock, par value $.01, of Merger Sub issued and outstanding immediately prior to the Effective Time shall be converted into and exchanged for one validly issued, fully paid and nonassessable share of common stock, no par value, of the Surviving Corporation. (f) Adjustments to Exchange Ratios. The number of shares to be issued pursuant to this Section 1.6 shall be adjusted to reflect fully the effect of any stock split, reverse split, stock dividend, reorganization, recapitalization or other like change with respect to Parent Shares or Company Common Stock occurring after the date hereof and prior to the Effective Time. (g) Fractional Shares. No certificates or scrip representing less than one Parent Share shall be issued upon the surrender or exchange of a certificate or certificates which immediately prior to the Effective Time represented outstanding Shares (the "CERTIFICATES"). In lieu of any such fractional share, each holder of Shares who would otherwise have been entitled to a fraction of a Parent Share upon surrender of Certificates for exchange shall be paid upon such surrender cash (without interest) as follows: (i) with respect to shares of Parent Common Stock, an amount determined by multiplying (A) the Average Common Price by (B) the fractional interest of Parent Common Stock to which such holder would otherwise be entitled and (ii) with respect to shares of Parent Preferred Stock, an amount determined by multiplying (a) the Average Preferred Price by (B) the fractional interest of Parent Preferred Stock to which such holder would otherwise be entitled. "AVERAGE PREFERRED PRICE" shall be determined by calculating the quotient of the Parent Preferred Stock Fair Market Value divided by 50,000. As soon as practical after determining the amount of cash, if any, to be paid to former holders of Company Common Stock with respect to any fractional Parent Shares, the Exchange Agent (as defined in Section 1.7(a)) shall promptly pay such amounts to such holders in accordance with Article I. Parent will make available to the Exchange Agent the cash necessary for this purpose. A-5 103 (h) Terms of Parent Preferred Stock. The Parent Preferred Stock shall have such terms as are set forth on the Certificate of Designation, Preferences and Rights of the series C Convertible Preferred Stock of Cabletron Systems, Inc. (the "SERIES C CERTIFICATE OF DESIGNATION") substantially in the form attached hereto as Exhibit 1.6(h). SECTION 1.7 Exchange of Certificates. (a) Exchange Agent. At the Effective Time, Parent shall supply, or shall cause to be supplied, to or for the account of Boston Equiserve, or such other bank or trust company as shall be designated by Parent (the "EXCHANGE AGENT"), in trust for the benefit of the holders of Company Common Stock, for exchange in accordance with this Section 1.7, through the Exchange Agent, a sufficient number of certificates evidencing the Parent Shares to effect the payment of the portion of the Aggregate Merger Consideration payable, subject to the provisions of Section 1.6(b) less the number of shares of Parent Common Stock to be deposited into the Escrow Fund (as defined in Section 8.3) and less the number of shares of Parent Preferred Stock to be held in escrow as provided herein. Parent shall cause all Parent Shares and all Shares to be issued in connection with the Merger to be duly authorized, validly issued, fully paid and nonassessable. (b) Exchange Procedures. As soon as reasonably practicable after the Effective Time, Parent will instruct the Exchange Agent to mail to each holder of record of Certificates (i) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon proper delivery of the Certificates to the Exchange Agent and shall be in such form and have such other provisions as Parent may reasonably specify that are not inconsistent with the terms of this Agreement), and (ii) instructions to effect the surrender of the Certificates in exchange for the Aggregate Merger Consideration. Upon surrender of a Certificate for cancellation to the Exchange Agent together with such letter of transmittal, duly executed, and such other customary documents as may be required pursuant to such instructions, the holder of such Certificate shall be entitled to receive in exchange therefor (A) certificates evidencing that number of whole shares of Parent Common Stock which such holder has the right to receive in accordance with the provisions of Section 1.6(b) in respect of the Shares formerly evidenced by such Certificate, less the number of shares of Parent Common Stock to be deposited in the Escrow Fund on such holder's behalf pursuant to Article VIII hereof, (B) certificates evidencing that number of whole shares of Parent Preferred Stock which such holder has the right to receive in accordance with the provisions of Section 1.6(b) in respect of the Shares formerly evidenced by such Certificate, which certificates shall be delivered to State Street Bank & Trust, as escrow agent (the "ESCROW AGENT"), and (C) cash in respect of fractional shares as provided in Section 1.6(g) (the Liquidation Preference Payments, Additional Merger Consideration and cash being collectively, the "AGGREGATE MERGER CONSIDERATION"), and the Certificate so surrendered shall forthwith be canceled. Until so surrendered, each outstanding Certificate that, prior to the Effective Time, represented Shares will be deemed from and after the Effective Time, for all corporate purposes, other than the payment of dividends and subject to Section 1.6(g), to evidence the ownership of the number of full Parent Shares into which such shares of Company Common Stock and Company Preferred Stock shall have been so converted. As soon as practicable after the Effective Time, and subject to and in accordance with the provisions of Section 8.3 hereof, Parent shall cause to be delivered to the Escrow Agent a certificate or certificates representing those shares of Parent Common Stock issued by Parent pursuant to Section 1.6(b) to be held in escrow by Escrow Agent as set forth in Section 1.7(b) of the Company Disclosure Schedule (as defined in Article II) ("ESCROW SHARES"), which shall be registered in the name of the Escrow Agent as nominee for the holders of certificates cancelled pursuant to this Section 1.7. The Escrow Shares shall be comprised entirely of shares of Parent Common Stock. Such shares shall be beneficially owned by such holders and shall be held in escrow and shall be available to compensate Parent for certain damages as provided in Article VIII. The Escrow Shares will appear as issued and outstanding on Parent's balance sheet and will be legally outstanding under applicable state law. All dividends paid on Escrow Shares (excluding any shares of Parent capital stock paid in connection with a stock split or stock dividend) will be distributed currently to each of the exchanging stockholders, and all voting rights of the Escrow Shares A-6 104 will be exercisable by or on behalf of each such stockholder. To the extent not used for such purposes, such shares shall be released, all as provided in Article VIII hereof. As soon as practicable after the Effective, Time, Parent shall cause to be delivered to the Escrow Agent all certificates representing the shares of Parent Preferred Stock (the "PARENT PREFERRED ESCROW SHARES"), which shall be registered in the name of the Escrow Agent as nominee for the holders of certificates cancelled pursuant to this Section 1.7. The entire portion of Parent Preferred Escrow Shares issuable to stockholders pursuant to Section 1.6(a) or Section 1.6(b) shall be deposited with the Escrow Agent. Such shares shall be beneficially owned by such holders and shall be held in escrow until the earliest to occur of the thirty (30) month anniversary of the Closing Date or any conversion or redemption of such shares in accordance with the terms of the Series C Certificate of Designation. The Parent Preferred Escrow Shares will appear as issued and outstanding on Parent's balance sheet and will be legally outstanding under applicable state law. All dividends paid on Parent Preferred Escrow Shares (excluding any shares of Parent capital stock paid in connection with a stock split or stock dividend) will be distributed currently to each of the exchanging Company stockholders, and all voting and other rights of the Preferred Parent Escrow Shares will be exercisable by or on behalf of each such stockholder. (c) Transfers of Ownership. If any certificate for Parent Shares is to be issued in, or any cash is to be paid to, a name other than that in which the Certificate surrendered in exchange therefor is registered, it will be a condition to the issuance or payment thereof that the Certificate so surrendered will be properly endorsed and otherwise in proper form for transfer and that the person requesting such exchange or payment will have paid to Parent or any agent designated by it any transfer or other taxes required by reason of the issuance of a certificate for Parent Shares in, or payment of cash to, any name other than that of the registered holder of the certificate surrendered, or have established to the satisfaction of Parent or any agent designated by it that such tax has been paid or is not payable. SECTION 1.8 Stock Transfer Books. At the Effective Time, the stock transfer books of the Company shall be closed, and there shall be no further registration of transfers of Company Common Stock thereafter on the records of the Company Preferred Stock of Company. SECTION 1.9 No Further Ownership Rights in Shares. The Aggregate Merger Consideration delivered upon the surrender for exchange of Shares in accordance with the terms hereof shall be deemed to have been issued in full satisfaction of all rights pertaining to such Shares, and there shall be no further registration of transfers on the records of the Surviving Corporation of Shares which were outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates are presented to the Surviving Corporation for any reason, they shall be canceled and exchanged as provided in this Article I. SECTION 1.10 Lost, Stolen or Destroyed Certificates. In the event any Certificates shall have been lost, stolen or destroyed, the Exchange Agent shall issue or pay the Aggregate Merger Consideration in exchange for such lost, stolen or destroyed Certificates, upon the making of an affidavit of that fact by the holder thereof; provided, however, that Parent may, in its discretion and as a condition precedent to the payment of the Aggregate Merger Consideration, require the owner of such lost, stolen or destroyed Certificates to deliver an agreement of indemnification in form reasonably satisfactory to Parent, or a bond in such sum as Parent may reasonably direct as indemnity against any claim that may be made against Parent or the Exchange Agent with respect to the Certificates alleged to have been lost, stolen or destroyed. SECTION 1.11 Tax Consequences. It is intended by the parties hereto that the transaction effected by the Merger shall constitute a reorganization within the meaning of Section 368(a) of the Code. The parties hereto hereby adopt this Agreement as a "plan of reorganization" within the meaning of Sections 1.368-2(g) and 1.368-3(a) of the United States Treasury Regulations. SECTION 1.12 Taking of Necessary Action; Further Action. Each of Parent, Merger Sub and, the Company will take all such reasonable and lawful action as may be necessary or appropriate in order to effectuate the Merger in accordance with this Agreement as promptly as possible.

SECTION 1.13 No Liability. Neither Parent, Merger Sub nor the Company shall be liable to any holder of Company Preferred Stock or Company Common Stock for any Aggregate Merger Consideration properly delivered to a public official pursuant to any applicable abandoned property, escheat or similar law following the passage of time specified therein. SECTION 1.14 Withholding Rights. Parent or the Exchange Agent shall be entitled to deduct and withhold from the Aggregate Merger Consideration otherwise payable pursuant to this Agreement to any holder of Company Preferred Stock or Company Common Stock such amounts as Parent or the Exchange Agent is required to deduct and withhold with respect to the making of such payment under the Code, or any provision of state, local or foreign tax law. To the extent that amounts are so withheld by Parent or the Exchange Agent, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the Shares in respect of which such deduction and withholding was made by Parent or the Exchange Agent. SECTION 1.15 Material Adverse Effect. When used in connection with the Company or Parent or any of Parent's subsidiaries, as the case may be, the term "MATERIAL ADVERSE EFFECT" means any change, effect or circumstance that, individually or when taken together with all other such changes, effects or circumstances that have occurred prior to the date of determination of the occurrence of the Material Adverse Effect, (a) is or is reasonably likely to be materially adverse to the business, assets (including intangible assets), prospects, financial condition or results of operations of the Company or Parent and its subsidiaries taken as a whole, or (b) is or is reasonably likely to materially delay or prevent the consummation of the transactions contemplated hereby.

All shares of Parent Common Stock subject to such claims shall remain in the Escrow Fund until the Damages are actually incurred or paid or until the Escrow Agent determines in its reasonably good faith judgment that no Damages will be required to be incurred or paid (in which event such shares shall be distributed to the stockholders of the Company in accordance with Section 8.8 below).

If the Stockholder Representative and Parent should so agree, a memorandum setting forth such agreement shall be prepared and signed by both parties and shall be furnished to the Escrow Agent. The Escrow Agent shall be entitled to rely on any such memorandum and shall distribute the Parent Common Stock or other property from the Escrow Fund in accordance with the terms thereof. (b) If no such agreement can be reached after good faith negotiation, either Parent or the Stockholder Representative may, by written notice to the other, demand arbitration of the matter unless the amount of the Damages is at issue in pending litigation with a third party, in which event arbitration shall not be commenced until such amount is ascertained or both parties agree to arbitration; and in either such event the matter shall be settled by arbitration conducted by the Arbitrator (as defined herein) under the Commercial Arbitration Rules of the American Arbitration Association. Within fifteen (15) days after such written notice is sent, Parent and the Stockholder Representative shall each select one arbitrator, and the two arbitrators so selected shall select a third arbitrator (the "ARBITRATOR"). (c) Judgment upon any award rendered by the arbitrators may be entered in any court having jurisdiction. Any such arbitration shall be held in Boston, Massachusetts under the commercial rules then in effect of the American Arbitration Association.

Ricci is hereby appointed as the representative (the "STOCKHOLDER REPRESENTATIVE") for and on behalf of the stockholders to take all actions necessary or appropriate in the judgment of the Stockholder Representative for the accomplishment of the terms of this Agreement, including the execution of the Escrow Agreement.

(b) The Stockholder Representative shall not be liable for any act done or omitted in such capacity while acting in good faith and in the exercise of reasonable judgment, and any act done or omitted pursuant to the advice of counsel shall be conclusive evidence of such good faith. The Principal Stockholders shall severally indemnify the Stockholder Representative and hold him harmless against any loss, liability or expense (including any expenses of legal counsel retained by the Stockholder Representative) incurred without gross negligence or bad faith on the part of the Stockholder Representative and arising out of or in connection with the acceptance or administration of his duties hereunder. (c) Any decision, act, consent or instruction of the Stockholder Representative shall constitute a decision of all stockholders for whom shares of Parent Common Stock or otherwise issuable to them are A-34 132 deposited in the Escrow Fund and shall be final, binding and conclusive upon every stockholder, and the Escrow Agent and any Indemnitee may rely upon any decision, act, consent or instruction of the Stockholder Representative as being the decision, act, consent or instruction of each and every stockholder. The Escrow Agent and any Indemnitee are hereby relieved from any liability to any person for acts done by them in accordance with such decision, act, consent or instruction of the Stockholder Representative. SECTION 8.10 Distribution Upon Termination of Escrow Period. Within five (5) business days following the Termination Date, the Escrow Agent shall deliver to the stockholders all of the Escrow Shares in the Escrow Fund in excess of any amount of such Escrow Shares reasonably necessary to satisfy any unsatisfied or disputed claims for Damages specified in any Officer's Certificate delivered to the Escrow Agent on or before the Termination Date. As soon as all such claims have been resolved, the Escrow Agent shall deliver to the stockholders all Escrow Shares remaining in the Escrow Fund and not required to satisfy such claims. Deliveries of Escrow Shares to the stockholders pursuant to this section shall be made in proportion to the allocation set forth in Section 8.3. SECTION 8.11 Third-Party Claims. In the event an Indemnitee becomes aware of a third-party claim which such Indemnitee believes may result in a demand against the Escrow Fund, such Indemnitee shall promptly notify the Stockholder Representative of such claim. Such Indemnitee shall have the right to settle any such claim with the written consent of the Stockholder Representative, which consent shall not be unreasonably withheld; provided, however, that the Stockholder Representative may, at his or her option, direct the settlement negotiations other than for claims related to (i) the Company Intellectual Property or (ii) disputes or disagreements with customers of Parent or Company. In the event that the Stockholder Representative consents to any such settlement, neither the stockholders nor the Stockholder Representative shall have any power or authority to object under Section 8.7 or any other provision of this Agreement to the amount of any claim by an Indemnitee against the Escrow Fund for indemnity with respect to such settlement (provided that the stockholders and the Stockholder Representative shall not be precluded from objecting that the claim is not the type of claim (but without objections to the amount of the claim) for which such Indemnitee is entitled to indemnification from the Escrow Fund). If any proceeding is commended, or if any claim, demand or assessment is asserted, in respect of which a claim for indemnification is or might be made against the Escrow Fund based on matters other than (i) the Company Intellectual Property or (ii) claims made by customers of Parent or Company, the Stockholder Representative may, at his or her option, contest or defend any such action, proceeding, claim, demand or assessment, with counsel selected by the Stockholder Representative who is reasonably acceptable to such Indemnitee; provided, however, that if such Indemnitee shall reasonably object to such control, then the Stockholder Representative and such Indemnitee shall cooperate in the defense of such matter; provided further, that the Stockholder Representative shall not admit any liability with respect thereto or settle, compromise, pay or discharge the same without the prior written consent of Parent, which consent shall not be unreasonably withheld. With respect to any claim for indemnification based on matters relating to the Company Intellectual Property, or customers of Company or Parent, an Indemnitee shall have the option to defend any such proceeding with counsel reasonably satisfactory to the Stockholder Representative, which consent shall not be unreasonably withheld. In the event that the Stockholder Representative consents to any such settlement, neither the stockholders nor the Stockholder Representative shall have any power or authority to object under Section 8.8 or any other provision of this Agreement to the amount of any claim by Parent against the Escrow Fund for indemnity with respect to such settlement (provided that the stockholders and the Stockholder Representative shall not be precluded form objecting that the claim is not the type of claim (but without objections to the amount of the claim) for which such Indemnitee is entitled to indemnification from the Escrow Fund). The Stockholder Representative or the Indemnitee, whichever is not controlling the defense of any matter, shall be entitled to participate in such defense, at such Indemnitee's or the stockholders' expense. Any costs of defense of third party claims up to $500,000 and fifty percent (50%) of the costs thereafter (including attorneys' fees), incurred on behalf of the Stockholder Representative or stockholders (calculated on a cumulative basis for all third party claims to which this Section 8.11 applies) shall be submitted to the Escrow Agent and reimbursed with shares from the Escrow Fund. For the purpose of reimbursing such costs, the Parent Common Stock in the Escrow Fund shall be valued at the average of the closing prices as reported in the edition of The Wall A-35 133 Street Journal distributed in New York, NY, of Parent Common Stock for the thirty (30) trading days prior to the date that an invoice for such costs is sent to the Escrow Agent. SECTION 8.12 Maximum Liability and Remedies. The rights of an Indemnitee to make claims upon the Escrow Fund in accordance with this Article VIII shall be the sole and exclusive remedy of such Indemnitee after the Effective Time with respect to any breach by Company under this Agreement and no current or former stockholder, option holder, warrant holder, director, officer, employee or agent of Company shall have any personal liability to an Indemnitee after the Effective Time as a result of such breach; provided, however, that nothing herein limits any potential remedies of Parent or the Surviving Corporation, arising under applicable state and federal laws with respect to any fraud, intentional misrepresentations or other willful misconduct. Nothing in this Agreement shall limit the liability of any Principal Stockholder in connection with any breach by such stockholder of the Stockholder Agreement. SECTION 8.13 Notices.

HARDING ---------------------------------- Name: Daniel J. Harding Title: Vice President of Business Development ACTON ACQUISITION CO. By: /s/ DANIEL J. HARDING ---------------------------------- Name: Daniel J. Harding Title: INDUS RIVER NETWORKS, INC. By: /s/ PER A. SUNEBY ---------------------------------- Name: Per A. Suneby Title: President and Chief Executive Officer A-42 140 ANNEX B SECTION 262 OF THE DELAWARE GENERAL CORPORATION LAW SEC.262. APPRAISAL RIGHTS (a) Any stockholder of a corporation of this State who holds shares of stock on the date of the making of a demand pursuant to subsection (d) of this section with respect to such shares, who continuously holds such shares through the effective date of the merger or consolidation, who has otherwise complied with subsection (d) of this section and who has neither voted in favor of the merger or consolidation nor consented thereto in writing pursuant to sec. 228 of this title shall be entitled to an appraisal by the Court of Chancery of the fair value of the stockholder's shares of stock under the circumstances described in subsections (b) and (c) of this section. As used in this section, the word "stockholder" means a holder of record of stock in a stock corporation and also a member of record of a nonstock corporation; the words "stock" and "share" mean and include what is ordinarily meant by those words and also membership or membership interest of a member of a nonstock corporation; and the words "depository receipt" mean a receipt or other instrument issued by a depository representing an interest in one or more shares, or fractions thereof, solely of stock of a corporation, which stock is deposited with the depository. (b) Appraisal rights shall be available for the shares of any class or series of stock of a constituent corporation in a merger or consolidation to be effected pursuant to sec. 251 (other than a merger effected pursuant to sec. 251(g) of this title), sec. 252, sec. 254, sec. 257, sec. 258, sec. 263 or sec. 264 of this title: (1) Provided, however, that no appraisal rights under this section shall be available for the shares of any class or series of stock, which stock, or depository receipts in respect thereof, at the record date fixed to determine the stockholders entitled to receive notice of and to vote at the meeting of stockholders to act upon the agreement of merger or consolidation, were either (i) listed on a national securities exchange or designated as a national market system security on an interdealer quotation system by the National Association of Securities Dealers, Inc. or (ii) held of record by more than 2,000 holders; and further provided that no appraisal rights shall be available for any shares of stock of the constituent corporation surviving a merger if the merger did not require for its approval the vote of the stockholders of the surviving corporation as provided in subsection (f) of sec. 251 of this title. (2) Notwithstanding paragraph (1) of this subsection, appraisal rights under this section shall be available for the shares of any class or series of stock of a constituent corporation if the holders thereof are required by the terms of an agreement of merger or consolidation pursuant to sec.sec. 251, 252, 254, 257, 258, 263 and 264 of this title to accept for such stock anything except: a. Shares of stock of the corporation surviving or resulting from such merger or consolidation, or depository receipts in respect thereof; b. Shares of stock of any other corporation, or depository receipts in respect thereof, which shares of stock (or depository receipts in respect thereof) or depository receipts at the effective date of the merger or consolidation will be either listed on a national securities exchange or designated as a national market system security on an interdealer quotation system by the National Association of Securities Dealers, Inc. or held of record by more than 2,000 holders; c. Cash in lieu of fractional shares or fractional depository receipts described in the foregoing subparagraphs a. and b. of this paragraph; or d. Any combination of the shares of stock, depository receipts and cash in lieu of fractional shares or fractional depository receipts described in the foregoing subparagraphs a., b. and c. of this paragraph. (3) In the event all of the stock of a subsidiary Delaware corporation party to a merger effected under sec. 253 of this title is not owned by the parent corporation immediately prior to the merger, appraisal rights shall be available for the shares of the subsidiary Delaware corporation. 141 (c) Any corporation may provide in its certificate of incorporation that appraisal rights under this section shall be available for the shares of any class or series of its stock as a result of an amendment to its certificate of incorporation, any merger or consolidation in which the corporation is a constituent corporation or the sale of all or substantially all of the assets of the corporation. If the certificate of incorporation contains such a provision, the procedures of this section, including those set forth in subsections (d) and (e) of this section, shall apply as nearly as is practicable. (d) Appraisal rights shall be perfected as follows: (1) If a proposed merger or consolidation for which appraisal rights are provided under this section is to be submitted for approval at a meeting of stockholders, the corporation, not less than 20 days prior to the meeting, shall notify each of its stockholders who was such on the record date for such meeting with respect to shares for which appraisal rights are available pursuant to subsection (b) or (c) hereof that appraisal rights are available for any or all of the shares of the constituent corporations, and shall include in such notice a copy of this section. Each stockholder electing to demand the appraisal of such stockholder's shares shall deliver to the corporation, before the taking of the vote on the merger or consolidation, a written demand for appraisal of such stockholder's shares. Such demand will be sufficient if it reasonably informs the corporation of the identity of the stockholder and that the stockholder intends thereby to demand the appraisal of such stockholder's shares. A proxy or vote against the merger or consolidation shall not constitute such a demand. A stockholder electing to take such action must do so by a separate written demand as herein provided. Within 10 days after the effective date of such merger or consolidation, the surviving or resulting corporation shall notify each stockholder of each constituent corporation who has complied with this subsection and has not voted in favor of or consented to the merger or consolidation of the date that the merger or consolidation has become effective; or (2) If the merger or consolidation was approved pursuant to sec. 228 or sec. 253 of this title, each constituent corporation, either before the effective date of the merger or consolidation or within ten days thereafter, shall notify each of the holders of any class or series of stock of such constituent corporation who are entitled to appraisal rights of the approval of the merger or consolidation and that appraisal rights are available for any or all shares of such class or series of stock of such constituent corporation, and shall include in such notice a copy of this section; provided that, if the notice is given on or after the effective date of the merger or consolidation, such notice shall be given by the surviving or resulting corporation to all such holders of any class or series of stock of a constituent corporation that are entitled to appraisal rights. Such notice may, and, if given on or after the effective date of the merger or consolidation, shall, also notify such stockholders of the effective date of the merger or consolidation. Any stockholder entitled to appraisal rights may, within 20 days after the date of mailing of such notice, demand in writing from the surviving or resulting corporation the appraisal of such holder's shares. Such demand will be sufficient if it reasonably informs the corporation of the identity of the stockholder and that the stockholder intends thereby to demand the appraisal of such holder's shares. If such notice did not notify stockholders of the effective date of the merger or consolidation, either (i) each such constituent corporation shall send a second notice before the effective date of the merger or consolidation notifying each of the holders of any class or series of stock of such constituent corporation that are entitled to appraisal rights of the effective date of the merger or consolidation or (ii) the surviving or resulting corporation shall send such a second notice to all such holders on or within 10 days after such effective date; provided, however, that if such second notice is sent more than 20 days following the sending of the first notice, such second notice need only be sent to each stockholder who is entitled to appraisal rights and who has demanded appraisal of such holder's shares in accordance with this subsection. An affidavit of the secretary or assistant secretary or of the transfer agent of the corporation that is required to give either notice that such notice has been given shall, in the absence of fraud, be prima facie evidence of the facts stated therein. For purposes of determining the stockholders entitled to receive either notice, each constituent corporation may fix, in advance, a record date that shall be not more than 10 days prior to the date the notice is given, provided, that if the notice is given on or after the effective date of the merger or consolidation, the record date shall be such effective date. If no record date is fixed and the notice is given prior to the effective date, the record date shall be the close of business on the day next preceding the day on which the notice is given. B-2 142 (e) Within 120 days after the effective date of the merger or consolidation, the surviving or resulting corporation or any stockholder who has complied with subsections (a) and (d) hereof and who is otherwise entitled to appraisal rights, may file a petition in the Court of Chancery demanding a determination of the value of the stock of all such stockholders. Notwithstanding the foregoing, at any time within 60 days after the effective date of the merger or consolidation, any stockholder shall have the right to withdraw such stockholder's demand for appraisal and to accept the terms offered upon the merger or consolidation. Within 120 days after the effective date of the merger or consolidation, any stockholder who has complied with the requirements of subsections (a) and (d) hereof, upon written request, shall be entitled to receive from the corporation surviving the merger or resulting from the consolidation a statement setting forth the aggregate number of shares not voted in favor of the merger or consolidation and with respect to which demands for appraisal have been received and the aggregate number of holders of such shares. Such written statement shall be mailed to the stockholder within 10 days after such stockholder's written request for such a statement is received by the surviving or resulting corporation or within 10 days after expiration of the period for delivery of demands for appraisal under subsection (d) hereof, whichever is later. (f) Upon the filing of any such petition by a stockholder, service of a copy thereof shall be made upon the surviving or resulting corporation, which shall within 20 days after such service file in the office of the Register in Chancery in which the petition was filed a duly verified list containing the names and addresses of all stockholders who have demanded payment for their shares and with whom agreements as to the value of their shares have not been reached by the surviving or resulting corporation. If the petition shall be filed by the surviving or resulting corporation, the petition shall be accompanied by such a duly verified list. The Register in Chancery, if so ordered by the Court, shall give notice of the time and place fixed for the hearing of such petition by registered or certified mail to the surviving or resulting corporation and to the stockholders shown on the list at the addresses therein stated. Such notice shall also be given by 1 or more publications at least 1 week before the day of the hearing, in a newspaper of general circulation published in the City of Wilmington, Delaware or such publication as the Court deems advisable. The forms of the notices by mail and by publication shall be approved by the Court, and the costs thereof shall be borne by the surviving or resulting corporation. (g) At the hearing on such petition, the Court shall determine the stockholders who have complied with this section and who have become entitled to appraisal rights. The Court may require the stockholders who have demanded an appraisal for their shares and who hold stock represented by certificates to submit their certificates of stock to the Register in Chancery for notation thereon of the pendency of the appraisal proceedings; and if any stockholder fails to comply with such direction, the Court may dismiss the proceedings as to such stockholder. (h) After determining the stockholders entitled to an appraisal, the Court shall appraise the shares, determining their fair value exclusive of any element of value arising from the accomplishment or expectation of the merger or consolidation, together with a fair rate of interest, if any, to be paid upon the amount determined to be the fair value. In determining such fair value, the Court shall take into account all relevant factors. In determining the fair rate of interest, the Court may consider all relevant factors, including the rate of interest which the surviving or resulting corporation would have had to pay to borrow money during the pendency of the proceeding. Upon application by the surviving or resulting corporation or by any stockholder entitled to participate in the appraisal proceeding, the Court may, in its discretion, permit discovery or other pretrial proceedings and may proceed to trial upon the appraisal prior to the final determination of the stockholder entitled to an appraisal. Any stockholder whose name appears on the list filed by the surviving or resulting corporation pursuant to subsection (f) of this section and who has submitted such stockholder's certificates of stock to the Register in Chancery, if such is required, may participate fully in all proceedings until it is finally determined that such stockholder is not entitled to appraisal rights under this section. (i) The Court shall direct the payment of the fair value of the shares, together with interest, if any, by the surviving or resulting corporation to the stockholders entitled thereto. Interest may be simple or compound, as the Court may direct. Payment shall be so made to each such stockholder, in the case of holders of uncertificated stock forthwith, and the case of holders of shares represented by certificates upon the surrender to the corporation of the certificates representing such stock. The Court's decree may be enforced as B-3 143 other decrees in the Court of Chancery may be enforced, whether such surviving or resulting corporation be a corporation of this State or of any state. (j) The costs of the proceeding may be determined by the Court and taxed upon the parties as the Court deems equitable in the circumstances. Upon application of a stockholder, the Court may order all or a portion of the expenses incurred by any stockholder in connection with the appraisal proceeding, including, without limitation, reasonable attorney's fees and the fees and expenses of experts, to be charged pro rata against the value of all the shares entitled to an appraisal. (k) From and after the effective date of the merger or consolidation, no stockholder who has demanded appraisal rights as provided in subsection (d) of this section shall be entitled to vote such stock for any purpose or to receive payment of dividends or other distributions on the stock (except dividends or other distributions payable to stockholders of record at a date which is prior to the effective date of the merger or consolidation); provided, however, that if no petition for an appraisal shall be filed within the time provided in subsection (e) of this section, or if such stockholder shall deliver to the surviving or resulting corporation a written withdrawal of such stockholder's demand for an appraisal and an acceptance of the merger or consolidation, either within 60 days after the effective date of the merger or consolidation as provided in subsection (e) of this section or thereafter with the written approval of the corporation, then the right of such stockholder to an appraisal shall cease. Notwithstanding the foregoing, no appraisal proceeding in the Court of Chancery shall be dismissed as to any stockholder without the approval of the Court, and such approval may be conditioned upon such terms as the Court deems just. (l) The shares of the surviving or resulting corporation to which the shares of such objecting stockholders would have been converted had they assented to the merger or consolidation shall have the status of authorized and unissued shares of the surviving or resulting corporation.

At the time of such delivery of the Escrow Shares and Parent Preferred Escrow Shares to the Escrow Agent, the Company shall provide the Escrow Agent with a list setting forth the name and address of each such stockholder and the number of Escrow Shares and/or Parent Preferred Escrow Shares which such stockholder is entitled to receive under the Merger Agreement, which list shall be attached hereto as Exhibit A (as amended from time to time pursuant to the terms of this Agreement, "Exhibit A"). The Escrow Agent shall be under no duty to examine such 145 certificates or to determine or inquire whether any such certificate complies with the requirements of the Merger Agreement, and shall have no liability or responsibility for the genuineness, validity or sufficiency of, or title to, any such certificate. 2. Beneficial Ownership, Voting, Dividend Rights, Transfer of Escrow Shares. A. The Escrow Shares and Parent Preferred Escrow Shares shall be beneficially owned by the stockholders of the Company entitled to receive them under the Merger Agreement and all voting rights shall be exercisable by or on behalf of each such stockholder (subject to Section 18(H) of this Agreement). Any and all dividends other than cash distributions (including, without limitation, any distribution of stock or other securities or property by way of a dividend, spinoff, reclassification, recapitalization or similar corporate re- arrangement or subdivision) paid by Cabletron with respect to the Escrow Shares or the Parent Preferred Escrow Shares shall be made to the Escrow Agent on behalf of the stockholders entitled to receive such distribution and such distribution shall be deemed to be a part of the Common Shares Escrow Fund or the Preferred Shares Escrow Fund, as applicable. Any and all cash distributions paid by Cabletron with respect to the Escrow Shares or the Parent Preferred Escrow Shares shall be distributed by Cabletron concurrently to the stockholders to which such shares relate. If any such cash dividends are paid to the Escrow Agent, such cash (i) shall not become part of the Escrow Funds, and (ii) shall be disbursed by the Escrow Agent to the stockholders entitled thereto (based upon Exhibit A). The Escrow Agent shall be under no duty or obligation to invest (or otherwise pay interest on) any such cash dividends received by it from time to time hereunder. B. Until such time as they are distributed as hereinafter provided, no Escrow Shares or Parent Preferred Shares, or any interest therein, shall be transferred, except under the laws of descent and distribution or to the partners or equity holders of any stockholder which is an entity. Any such transfer by a stockholder of Escrow Shares and/or Parent Preferred Escrow Shares shall be effected by delivery to the Escrow Agent, the Stockholder Representative and Cabletron of appropriate written transfer instructions substantially in the form attached hereto as Exhibit B-1, together with a duly executed irrevocable stock power substantially in the form attached hereto as Exhibit B-2. Upon receipt of such written transfer instructions and stock power, duly executed with signatures guaranteed, the Escrow Agent shall amend Exhibit A hereto to include the name of the transferee and the number of Escrow Shares and/or Parent Preferred Escrow Shares to which such transferee is entitled, and shall correspondingly adjust the number of Escrow Shares and/or Parent Preferred Escrow Shares which the transferor is entitled to receive. Any reference to any "stockholder" herein, shall be deemed to include and apply to any transferee pursuant to this Section 2(B) who is, at the relevant time, the beneficial owner of any Escrow Shares or Parent Preferred Shares as reflected on Exhibit A, unless the context otherwise requires. 3. Stockholder Representative. A. For all purposes set forth in this Agreement including the right to receive the Notice (as defined in Section 4(A) below) and to provide the Counter Notice (as defined in Section 4(B) below) and the Non-Dispute Notice (as defined in Section 4(B) below), the Company hereby appoints Stephen J. Ricci as the representative for and on behalf of the stockholders of the Company. Any decision, act, consent or instruction of the Stockholder Representative shall constitute a decision of all stockholders for whom Escrow Shares or Parent Preferred Escrow Shares issuable to them are deposited in the Escrow Funds and shall be final, binding and conclusive upon every stockholder, and the Escrow Agent and any Indemnitee may rely upon any decision, act, consent or instruction of the Stockholder Representative as being the decision, act, consent or instruction of each and every stockholder. Notices of communications to or from the Stockholder Representative shall constitute notice to or from each of the stockholders. B. No bond shall be required of the Stockholder Representative and the Stockholder Representative shall receive no compensation for his services. The Stockholder Representative shall not be liable for any act done or omitted in such capacity while acting in good faith and in the exercise of reasonable judgment, and any act done or omitted pursuant to the advice of counsel shall be conclusive evidence of such good faith. The Escrow Agent and any Indemnitee are hereby relieved from any liability to any person for acts done by them in accordance with such decision, act, consent or instruction of the Stockholder Representative. The Principal C-2 146 Stockholders have agreed to severally indemnify the Stockholder Representative and hold him harmless against any liability, loss or expense (including any expenses of legal counsel retained by the Stockholder Representative) incurred without gross negligence or bad faith on the part of the Stockholder Representative and arising out of or in connection with the acceptance or administration of his duties hereunder and under the Merger Agreement. C. The holders of a majority in interest of Escrow Shares held in the Common Shares Escrow Fund may remove and replace the Stockholder Representative upon not less than ten (10) days' prior written notice to Cabletron and the Escrow Agent. If the Stockholder Representative resigns, dies, or is otherwise no longer able or willing to serve as the Stockholder Representative, a new Stockholder Representative shall be chosen within thirty (30) days of such event, by the holders of a majority in interest of Escrow Shares held in the Common Shares Escrow Fund, and prompt written notice of such replacement shall be given by such holders to Cabletron and the Escrow Agent. Any resignation of the Stockholder Representative shall not be effective until such a successor shall exist. The choice of a successor Stockholder Representative appointed in any manner permitted above shall be final and binding upon all of the stockholders. The decisions and actions of any successor Stockholder Representative shall be, for all purposes, those of the Stockholder Representative as if originally named herein. 4. Distribution of the Escrow Shares. A. At any time and from time to time, on or before the first anniversary of the Closing (the "Termination Date"), Cabletron may provide written notice (a "Notice") to the Escrow Agent specifying in reasonable detail the nature and dollar amount of any Damages incurred subject to indemnification under Article VIII of the Merger Agreement. Such Notice shall consist of a certificate executed by a duly authorized officer of Cabletron, certifying in reasonable detail, (i) that an Indemnitee has incurred, paid or properly accrued (in accordance with GAAP) or knows of facts giving rise to a reasonable probability that it will have to incur, pay or accrue (in accordance with GAAP) Damages in an aggregate stated amount with respect to which such Indemnitee is entitled to payment from the Common Shares Escrow Fund pursuant to the Merger Agreement, and (ii) the individual items of Damages included in the amount so stated, the date each such item was incurred, paid or properly accrued (in accordance with GAAP), or the basis for such anticipated liability and the specific nature of the breach to which such item is related. B. At the time of delivery of any Notice to the Escrow Agent, a duplicate copy of such Notice shall be delivered by Cabletron to the Stockholder Representative. If the Stockholder Representative shall provide written notice to Cabletron and the Escrow Agent disputing any Damages set forth in the Notice (a "Counter Notice") within thirty (30) days following receipt by the Stockholder Representative of such Notice, such dispute shall be resolved as provided in subsection 4(C) below. If no Counter Notice is received by the Escrow Agent within thirty (30) days of the Escrow Agent's receipt of a Notice, or if prior to the expiration of such thirty (30) day period the Escrow Agent shall have received written notification from the Stockholder Representative that it does not dispute the Damages set forth in the Notice (a "Non-Dispute Notice"), then the dollar amount of Damages claimed by Cabletron as set forth in its Notice shall be deemed established for purposes of this Agreement and the Merger Agreement and, after the earlier of the expiration of such thirty (30) day period or receipt by the Escrow Agent of a Non-Dispute Notice, the Escrow Agent shall deliver to such Indemnitee Escrow Shares in an amount necessary to indemnify such Indemnitee for the Damages claimed (based on the applicable Determination Price, as of the date of expiration of such 30 day period, as determined pursuant to Section 4(F) hereof), as nearly practicable, rounded up to the nearest whole share. C. If a Counter Notice is given by the Stockholder Representative in response to a Notice, the Stockholder Representative and Cabletron shall use good faith attempts over a thirty (30) day period to agree upon the rights of the respective parties with respect to each claim for Damages set forth in such Notice. If the Stockholder Representative and Cabletron should so agree within such thirty (30) day period, a memorandum setting forth such agreement shall be prepared and signed by both parties and shall be furnished to the Escrow Agent (which memorandum shall, at a minimum, specify the amount of Damages to be paid from the Common Shares Escrow Fund and the Determination Price to be applied for purposes thereof). The Escrow C-3 147 Agent shall be entitled to rely on any such memorandum and shall distribute the Escrow Shares from the Common Shares Escrow Fund in accordance with the terms thereof. If no such agreement can be reached after good faith negotiation within such thirty (30) day period, either Cabletron or the Stockholder Representative may, by written notice to the other, initiate arbitration of the matter (unless the amount of the Damages at issue is in pending litigation with a third party, in which event arbitration shall not be commenced until such amount is ascertained or both parties agree to arbitration). Within fifteen (15) days after such written notice is sent, Cabletron and the Stockholder Representative shall each select one arbitrator, and the two arbitrators so selected shall select a third arbitrator (collectively, the "Arbitrators"). Judgment upon any award rendered by the Arbitrators may be entered in any court having jurisdiction. Any such arbitration shall be held in Boston, Massachusetts under the commercial rules then in effect of the American Arbitration Association (the "AAA"). The costs of any such arbitration shall be borne one-half for the account of Cabletron and one-half by the stockholders. The Escrow Agent is authorized and directed to make any distribution out of the Common Shares Escrow Fund upon its receipt of written notice from either Cabletron or the Stockholder Representative of a judgment rendered by a court upon any such Arbitrators' award determining that an amount (specified therein) is owed to Cabletron in respect of a claim for Damages, with a copy of such court judgment attached (such distribution to be made on the basis of the applicable Determination Price as of the date on which the Escrow Agent receives such notice, as determined pursuant to Section 4(F) hereof, rounded up to the nearest whole share). D. The Escrow Agent is also directed and authorized to make distributions out of the Common Shares Escrow Fund to Cabletron upon receipt of any court order determining that an amount is owed to Cabletron pursuant to Article VIII of the Merger Agreement (such distribution to be based upon the applicable Determination Price as of the date of the Escrow Agent's receipt of such court order, as determined pursuant to Section 4(F), and rounded up to the nearest whole share). Cabletron shall provide the Stockholder Representative a copy of such court order. The Escrow Agent shall be authorized to act on such court order without further inquiry. E. Within five (5) business days following the Termination Date, the Escrow Agent shall deliver to the stockholders all of the Escrow Shares that remain in the Common Shares Escrow Fund (if any), less the number of Escrow Shares (rounded up to the nearest whole share) in such Common Shares Escrow Fund as is most nearly equal to the amount reasonably necessary to satisfy any unsatisfied or disputed claims for Damages specified in any Notice delivered to the Escrow Agent on or before the Termination Date, which has not been paid or resolved in accordance with Section 4(C) hereof (based upon the Determination Price, determined as of the Termination Date pursuant to Section 4(F) hereof). As soon as all such claims have been resolved pursuant to Section 4(C), the Escrow Agent shall deliver to each of the stockholders on whose behalf the Escrow Shares are held, all Escrow Shares remaining in the Common Shares Escrow Fund and not required to satisfy such claims. Deliveries of Escrow Shares to the stockholders pursuant to this section shall be made in such amounts as are set forth next to each stockholder's name on Exhibit A hereto, or if less than all such Escrow Shares shall be delivered, in proportion to each such stockholder's pro rata percentage of the Escrow Shares remaining in the Common Shares Escrow Fund. F. (i) In determining the number of Escrow Shares to be delivered in respect of any claim for Damages pursuant to this Agreement, the Escrow Shares in the Common Shares Escrow Fund shall be valued at the average of the closing prices as reported in the edition of The Wall Street Journal distributed in New York, NY of Parent Common Stock for the thirty (30) trading days prior to the applicable date as of which such value is to be determined for purposes of, and as provided in, this Agreement (the "Determination Price"). At any time or times when a distribution of Escrow Shares is called for under this Agreement, the Escrow Agent shall be entitled to request and receive from Cabletron or the Stockholder Representative, and shall be entitled to rely conclusively upon, a certificate to the Escrow Agent executed by Cabletron and the Stockholder Representative setting forth the Determination Price (as of the date or dates requested by the Escrow Agent); and the Escrow Agent shall not be liable for any delay or error on the part of Cabletron or the Stockholder Representative in making such determination or providing such certification. If for any reason closing prices for the relevant thirty trading days are not reported in The Wall Street Journal as provided above with respect to any such determination, the Determination Price shall be determined by the mutual agreement of C-4 148 Cabletron and the Stockholder Representative and certified to the Escrow Agent, on which it shall be entitled to rely conclusively, on the basis of such methodology as shall be agreed upon by Cabletron and the Stockholder Representative; and the Escrow Agent shall have no liability for any delay or error on the part of Cabletron or the Stockholder Representative in making such determination or providing such certificate. (ii) The Stockholder Representative shall have the option to compensate an Indemnitee for any Damages, or any portion of such Damages, with cash rather than Escrow Shares. Upon satisfaction of any claim with cash, a number of Escrow Shares shall be released by the Escrow Agent to the Stockholder Representative equal to the total dollar amount of such cash used to pay such claim divided by the Determination Price; provided, however that (i) with respect to an undisputed claim for Damages, the Stockholder Representative shall give written notice to the Escrow Agent executed by the Stockholder Representative and acknowledged in writing by Cabletron (which acknowledgement shall not be unreasonably withheld) of the amount it elects to pay in cash (a "Cash Payment Notice"), and shall pay such cash amount specified therein to the Escrow Agent in immediately available funds by the earlier of thirty (30) days from the Escrow Agent's receipt of a Notice or the Escrow Agent's receipt of a Non-Dispute Notice, and (ii) with respect to a disputed claim for Damages, the Stockholder Representative shall give a Cash Payment Notice to the Escrow Agent, together with payment in immediately available funds of the amount to be paid in cash concurrently with or prior to the Escrow Agent's receipt of the memorandum described in Section 4(C) hereof or decision of Arbitrators described in Section 4(C) hereof or the court order described in Section 4(C) hereof, as the case may be. The Escrow Agent shall not be under any duty or obligation to invest (or otherwise pay interest on) any such cash received by it at any time or times hereunder. G. The rights of an Indemnitee to make claims upon the Escrow Fund shall be the sole and exclusive remedy of such Indemnitee with respect to any breach by Company under the Merger Agreement and the transactions contemplated thereby and no current or former stockholder, option holder, warrant holder, director, officer, employee or agent of Company shall have any personal liability to an Indemnitee as a result of such breach; provided, however, that nothing herein or in the Merger Agreement shall limit any potential remedies of Cabletron or the Surviving Corporation, arising under applicable state and federal laws with respect to any fraud, intentional misrepresentations or other willful misconduct. Nothing in this Agreement or the Merger Agreement shall limit the liability of any Principal Stockholder in connection with any breach by such stockholder of the Stockholder Agreement executed by such Principal Stockholder. 5. Distribution of Parent Preferred Escrow Shares. The Parent Preferred Escrow Shares shall be held by the Escrow Agent in the Preferred Shares Escrow Fund and shall not be distributed except in accordance with the provisions of this Section 5. (i) If, during the one-year period ending with the first anniversary of the Closing Date, Cabletron shall establish a record date with respect to an Enterasys Spinoff or an Enterasys Transaction to be completed prior to the first anniversary of the Closing Date, then pursuant to Section 6 and Section 7 of Cabletron's Certificate of Designation, Preferences and Rights of the Series C Convertible Preferred Stock (the "Series C Designation"), Cabletron shall deliver to each holder of Series C Preferred Stock set forth on Exhibit A, and to the Escrow Agent, not less than thirty (30) days written notice of the record date for the Enterasys Spinoff or the Enterasys Transaction. Such notice shall specify (a) whether it relates to an Enterasys Spinoff or an Enterasys Transaction, (b) in the case of an Enterasys Spinoff, each holder's right to convert its shares of Series C Preferred Stock into Cabletron Common Stock, or, in the case of an Enterasys Transaction, each holder's right to convert or redeem its shares of Series C Preferred Stock, (c) the applicable conversion and redemption prices set forth in the Series C Designation, and (d) the applicable procedures and notice requirements for conversion or redemption set forth herein and in Section 6 and Section 7 of the Series C Designation. Each holder of Series C Preferred Stock shall have fifteen (15) days from the date of such notice to deliver to the Escrow Agent written notice of its intention to convert or redeem, or its objection to any conversion or redemption of its shares of Series C Preferred Stock, as applicable. With respect to an Enterasys Spinoff, promptly following the expiration of such fifteen (15) day period, the Escrow Agent shall deliver to Cabletron the certificate or certificates representing the Parent Preferred Escrow Shares together with a list of each holder of Parent Preferred Escrow Shares set forth on Exhibit A C-5 149 from whom the Escrow Agent has received within such fifteen (15) day period written notice electing to convert such holder's shares of Series C Preferred Stock into Cabletron Common Stock, or from whom the Escrow Agent has not received within such fifteen (15) day period any objection in writing to such conversion, or from whom the Escrow Agent has not received written notice with respect to such conversion (or any notice at all) within such fifteen (15) day period. The Escrow Agent may request, from time to time, written confirmation executed by Cabletron and the Stockholder Representative of the information compiled by the Escrow Agent and set forth on the list delivered to Cabletron. Cabletron shall then, immediately prior to consummation of the Enterasys Spinoff, (i) convert into Cabletron Common Stock the Parent Preferred Escrow Shares of each holder set forth on such list, and deliver such Cabletron Common Stock to such holder, all in the manner provided in the Series C Designation, and (ii) return to the Escrow Agent a certificate, registered in the name of Embassy & Co., as nominee for the Escrow Agent, representing the balance of Parent Preferred Escrow Shares not so converted, together with an amended Exhibit A properly adjusted to reflect such conversion. With respect to an Enterasys Transaction, promptly following the expiration of such fifteen (15) day period, the Escrow Agent shall deliver to Cabletron the certificate or certificates representing the Parent Preferred Escrow Shares together with a list of each holder of Parent Preferred Escrow Shares set forth on Exhibit A from whom the Escrow Agent has received within such fifteen (15) day period written notice electing to redeem such holder's shares of Series C Preferred Stock, or from whom the Escrow Agent has not received within such fifteen (15) day period any objection in writing to such redemption, or from whom the Escrow Agent has not received within such fifteen (15) day period written notice electing to convert such holder's shares of Series C Preferred Stock into Cabletron Common stock, or from whom the Escrow Agent has not received written notice with respect to such conversion or redemption (or any notice at all) within such fifteen (15) day period. The Escrow Agent may request, from time to time, written confirmation executed by Cabletron and the Stockholder Representative of the information compiled by the Escrow Agent and set forth on the list delivered to Cabletron. Cabletron shall then, immediately prior to consummation of the Enterasys Transaction, (i) redeem the Parent Preferred Escrow Shares of any holder set forth on such list, and shall deliver the redemption proceeds therefrom to such holder, in the manner provided in the Series C Designation, and (ii) return to the Escrow Agent a certificate registered in the name of Embassy & Co., as nominee for the Escrow Agent, representing the balance of Parent Preferred Escrow Shares not so redeemed, together with an amended Exhibit A properly adjusted to reflect such redemption. If, within fifteen (15) days of the written notice from Cabletron of the record date for the Enterasys Transaction, the Escrow Agent has received written notice from a holder of Series C Preferred Stock set forth on Exhibit A electing conversion of such holder's Series C Preferred Stock into Cabletron Common Stock, then the Escrow Agent shall promptly after the expiration of such fifteen (15) day period deliver to Cabletron the certificate or certificates representing the Parent Preferred Escrow Shares (unless already delivered to Cabletron pursuant to the preceding paragraph) together with a list of the holders from whom it has received such notice electing conversion. The Escrow Agent may request written confirmation, from time to time, executed by Cabletron and the Stockholder Representative of the information compiled by the Escrow Agent and set forth on the list delivered to Cabletron. Cabletron shall then, immediately following the consummation of the Enterasys Transaction, (i) convert into Cabletron Common Stock the Parent Preferred Escrow Shares of any holder set forth on such list and deliver such Cabletron Common Stock to such holder, all in the manner provided in the Series C Designation, and (ii) return to the Escrow Agent a certificate, registered in the name of Embassy & Co., as nominee for the Escrow Agent, representing the balance of Parent Preferred Escrow Shares not so converted, together with an amended Exhibit A properly adjusted to reflect such conversion. Any Parent Preferred Escrow Shares not so converted or redeemed (whether upon written notice of the holder or as a result of the failure to consummate an Enterasys Spinoff or an Enterasys Transaction, as applicable) shall remain in the Preferred Shares Escrow Fund and shall not be distributed except in accordance with the provisions of this Section 5. (ii) If, during the one-year period ending with the second anniversary of the Closing Date, Cabletron shall establish a record date with respect to an Enterasys Spinoff or an Enterasys Transaction to be completed C-6 150 prior to the second anniversary of the Closing Date, then pursuant to Section 6 and Section 7 of the Series C Designation, Cabletron shall deliver to each holder of Series C Preferred Stock set forth on Exhibit A, and to the Escrow Agent, not less than thirty (30) days written notice of the record date for the Enterasys Spinoff or the Enterasys Transaction, as applicable. Such notice shall specify (a) whether it relates to an Enterasys Spinoff or an Enterasys Transaction, (b) each holder's right to convert its shares of Series C Preferred Stock into shares of Cabletron Common Stock or to redeem its shares of Series C Preferred Stock, (c) the applicable conversion and redemption prices set forth in the Series C Designation, and (d) the applicable procedures and notice requirements for conversion or redemption set forth herein and in Section 6 and Section 7 of the Series C Designation. Each holder of Series C Preferred Stock shall have fifteen (15) days from the date of such notice to deliver to the Escrow Agent written notice of its intention to convert or redeem, or its objection to any conversion or redemption of its shares of Series C Preferred Stock, as applicable. Promptly following the expiration of such fifteen (15) day period, the Escrow Agent shall deliver to Cabletron the certificate or certificates representing the Parent Preferred Escrow Shares together with a list of each holder of Parent Preferred Escrow Shares set forth on Exhibit A from whom the Escrow Agent has received within such fifteen (15) day period written notice electing to redeem such holder's shares of Series C Preferred Stock, or from whom the Escrow Agent has not received within such fifteen (15) day period any objection in writing to such redemption, or from whom the Escrow Agent has not received within such fifteen (15) day period written notice electing to convert such holder's shares of Series C Preferred Stock into Cabletron Common stock, or from whom the Escrow Agent has not received written notice with respect to such conversion or redemption (or any notice at all) within such fifteen (15) day period. The Escrow Agent may request, from time to time, written confirmation executed by Cabletron and the Stockholder Representative of the information compiled by the Escrow Agent and set forth on the list delivered to Cabletron. Cabletron shall then, immediately following the consummation of the Enterasys Spinoff or Enterasys Transaction, as the case may be, (i) redeem the Parent Preferred Escrow Shares of any holder set forth on such list, and shall deliver the redemption proceeds therefrom to such holder, in the manner provided in the Series C Designation, and (ii) return to the Escrow Agent a certificate registered in the name of Embassy & Co., as nominee for the Escrow Agent, representing the balance of Parent Preferred Escrow Shares not so redeemed, together with an amended Exhibit A properly adjusted to reflect such redemption. If, within fifteen (15) days of the written notice from Cabletron of the record date for the Enterasys Spinoff or Enterasys Transaction, as the case may be, the Escrow Agent has received written notice from a holder of Series C Preferred Stock set forth on Exhibit A electing conversion of such holder's Series C Preferred Stock into Cabletron Common Stock, then the Escrow Agent shall promptly after the expiration of such fifteen (15) day period deliver to Cabletron the certificate or certificates representing the Parent Preferred Escrow Shares (unless already delivered to Cabletron pursuant to the preceding paragraph) together with a list of the holders from whom it has received such notice electing conversion. The Escrow Agent may request, from time to time, written confirmation executed by Cabletron and the Stockholder Representative of the information compiled by the Escrow Agent and set forth on the list delivered to Cabletron. Cabletron shall then, immediately following the consummation of the Enterasys Spinoff or Enterasys Transaction, as the case may be, (i) convert into Cabletron Common Stock the Parent Preferred Escrow Shares of any holder set forth on such list and deliver such Cabletron Common Stock to such holder, all in the manner provided in the Series C Designation, and (ii) return to the Escrow Agent a certificate, registered in the name of Embassy & Co., as nominee for the Escrow Agent, representing the balance of Parent Preferred Escrow Shares not so converted, together with an amended Exhibit A properly adjusted to reflect such conversion. Any Parent Preferred Escrow Shares not so redeemed or converted (whether upon written notice of the holder or as a result of the failure to consummate an Enterasys Spinoff or an Enterasys Transaction) shall remain in the Preferred Shares Escrow Fund and shall not be distributed except in accordance with the provisions of this Section 5. (iii) Within thirty (30) days of the two-year anniversary of the Closing Date, Cabletron shall deliver to each holder of Series C Preferred Stock and to the Escrow Agent a written notice in accordance with Section 6 and Section 7 of the Series C Designation. Such notice shall (a) advise such holder of the termination of such holder's redemption right, (b) advise such holder of such holder's right to convert its C-7 151 shares of Series C Preferred Stock into shares of Cabletron Common Stock, (c) specify the applicable conversion price set forth in the Series C Designation, and (d) specify the applicable procedures and notice requirements for conversion set forth herein and in Section 6 and Section 7 of the Series C Designation. Each holder of Series C Preferred Stock shall have fifteen (15) days from the date of such notice to deliver to the Escrow Agent written notice of its intention to convert or its objection to any conversion of its shares of Series C Preferred Stock. Promptly following the expiration of such fifteen (15) day period, the Escrow Agent shall deliver to Cabletron the certificate or certificates representing the Parent Preferred Escrow Shares together with a list of each holder of Parent Preferred Escrow Shares set forth on Exhibit A from whom the Escrow Agent has received within such fifteen (15) day period written notice electing to convert such holder's shares of Series C Preferred Stock, or from whom the Escrow Agent has not received within such fifteen (15) day period any objection in writing to such conversion, or from whom the Escrow Agent has not received written notice with respect to such conversion (or any notice at all) within such fifteen (15) day period. The Escrow Agent may request, from time to time, written confirmation executed by Cabletron and the Stockholder Representative of the information compiled by the Escrow Agent and set forth on the list delivered to Cabletron. Cabletron shall then, (i) convert into Cabletron Common Stock the Parent Preferred Escrow Shares of each holder set forth on such list, and deliver such Cabletron Common Stock to such holder, all in the manner provided in the Series C Designation, and (ii) return to the Escrow Agent a certificate, registered in the name of Embassy & Co., as nominee for the Escrow Agent, representing the balance of Parent Preferred Escrow Shares not so converted, together with an amended Exhibit A properly adjusted to reflect such conversion. Any Parent Preferred Escrow Shares not so converted shall remain in the Preferred Shares Escrow Fund and shall not be distributed except in accordance with the provisions of this Section 5. (iv) Promptly following the thirty (30) month anniversary of the Closing Date (as identified to the Escrow Agent in the Cabletron notice accompanying deposit of the Escrow Shares and Parent Preferred Escrow Shares pursuant to Section 1), the Escrow Agent shall release any Parent Preferred Escrow Shares remaining in the Preferred Shares Escrow Fund and shall distribute such Parent Preferred Escrow Shares to each of the holders to which such Parent Preferred Escrow Shares relate in the amounts set forth on Exhibit A. (v) Notwithstanding anything to the contrary in this Section 5, in the event of the consummation of a Corporate Change (as defined in the Series C Designation) at any time prior to the Termination Date, Cabletron shall deliver to the Escrow Agent the stock, securities or assets to which the holders of Series C Preferred Stock set forth on Exhibit A are entitled as consideration in connection with the Corporate Change, as provided in Section 6.4 of the Series C Designation, accompanied by a certificate (i) stating that such delivery is in connection with a Corporate Change as provided in Section 6.4 of the Series C Designation, (ii) certifying that the stock, securities or assets delivered therewith constitute all of the assets to which the holders of Series C Preferred Stock set forth on Exhibit A are entitled as consideration in connection with such Corporate Change as provided in Section 6.4 of the Series C Designation, (iii) identifying the specific amount(s) or portion(s) of such stock, securities and/or assets (as applicable) to which each such holder set forth on Exhibit A is entitled, respectively, and (iv) directing the Escrow Agent to deliver to Cabletron any and all certificates representing Parent Preferred Escrow Shares then held by the Escrow Agent (a "Corporate Change Notice"); and the Escrow Agent shall concurrently deliver to Cabletron the certificate or certificates representing such holders' Parent Preferred Escrow Shares. Promptly thereafter, the Escrow Agent shall distribute to each of the holders set forth on Exhibit A, the amount of such stock, securities or assets to which each holder is entitled as set forth in the Corporate Change Notice. 6. Duties and Powers of Escrow Agent. A. The Escrow Agent shall not be under any duty to give the Escrow Funds held by it hereunder any greater degree of care than it gives its own similar property and shall not be required to invest any shares or funds held hereunder. Uninvested shares or funds held hereunder shall not earn or accrue interest. C-8 152 B. The Escrow Agent shall be entitled to rely upon any order, judgment, certification, demand, notice, instrument or other writing delivered to it hereunder without being required to determine the authenticity or the correctness of any fact stated therein or the propriety or validity of the service thereof. The Escrow Agent may act in reliance upon any instrument or signature believed by it to be genuine and may assume that the person purporting to give receipt or advice or make any statement or execute any document in connection with the provisions hereof has been duly authorized to do so. The Escrow Agent may conclusively presume that the undersigned representative of any party hereto which is an entity other than a natural person has full power and authority to instruct Escrow Agent on behalf of that party unless written notice to the contrary is delivered to the Escrow Agent. C. The Escrow Agent may act pursuant to the advice of counsel with respect to any matter relating to this Agreement and shall not be liable for any action taken or omitted by it in good faith in accordance with such advice. D. The Escrow Agent does not have any interest in the Escrow Funds deposited hereunder, but is serving as escrow holder only and having only possession thereof. Any payments of income from the Escrow Funds shall be subject to withholding regulations then in force with respect to United States taxes. If requested by the Escrow Agent, the parties hereto will provide the Escrow Agent with appropriate Internal Revenue Service Forms W-9 for tax identification number certification, or non-resident alien certifications at the Closing. Such forms, if requested by the Escrow Agent, shall be provided to the recipient of any distributions from the Escrow Funds by Escrow Agent prior to making any such distributions from the Escrow Funds. E. The other parties hereto authorize the Escrow Agent, for any securities held hereunder, to use the services of any United States central securities depository, including, without limitation, the Depository Trust Company and the Federal Reserve Book Entry System. F. In the event of any disagreement between the other parties hereto resulting in adverse claims or demands being made in connection with the Common Shares Escrow Fund or in the event that the Escrow Agent is in doubt as to what action it should take hereunder, the Escrow Agent shall be entitled to retain the Common Shares Escrow Fund until the Escrow Agent shall have received (i) a final order of the Arbitrators acting in accordance with Section 4(C) hereof directing delivery of the Common Shares Escrow Fund, (ii) a final non-appealable order of a court of competent jurisdiction directing delivery of the Common Shares Escrow Fund, or (iii) a written agreement executed by all of the other parties hereto directing delivery of the Common Shares Escrow Fund, in which event the Escrow Agent shall disburse the Common Shares Escrow Fund in accordance with such order or agreement without further inquiry. The Escrow Agent shall act on such arbitration or court order without further inquiry. 7. Limited Liability. In performing any of its duties hereunder, the Escrow Agent shall not incur any liability to anyone for any damages, losses, or expenses, except for any willful misconduct or gross negligence by the Escrow Agent hereunder, and, accordingly, the Escrow Agent shall not incur any such liability with respect to (i) any action taken or omitted in good faith upon advice of its legal counsel given with respect to any questions relating to the duties and responsibilities of the Escrow Agent under this Agreement or (ii) any action taken or omitted in reliance on any instrument, including any written notice or instruction provided for in this Agreement, not only as to its due execution and authorization, and the validity and effectiveness of its provisions, but also as to the truth and accuracy of any information contained therein, which the Escrow Agent shall in good faith believe to be genuine, to have been signed or presented by a person or persons having authority to sign or present such instrument, and to conform with the provisions of this Agreement. 8.

If the Escrow Agent has not received a designation of a successor escrow agent within thirty (30) days of the notice of resignation or removal, the Escrow Agent's sole responsibility after that time shall be to interplead and deposit the Escrow Funds with the arbitrator whereupon its duties hereunder shall cease. 10.

The headings of sections in this Agreement are provided for convenience only and will not affect its construction or interpretation. C-12 156 G. The Escrow Agent is not a party to, nor is it bound by, nor need it give consideration to the terms or provisions of, any agreement or undertaking among the undersigned or any of them, or between the undersigned or any of them and other persons, including, but not limited to, the Merger Agreement, the Series C Designation, or any agreement or undertaking which may be evidenced by or disclosed by the Escrow Funds, it being the intention of the parties hereto that the Escrow Agent assent to and be obligated to give consideration only to the terms and provisions hereof. The Escrow Agent's receipt of a copy of the Merger Agreement is solely for the purpose of providing to the Escrow Agent access to the defined terms appearing therein. H. Neither the Escrow Agent nor its nominee shall be under any duty to take any action to preserve, protect, exercise or enforce any rights or remedies under or with respect to the Escrow Shares or the Parent Preferred Escrow Shares, or any other securities or assets held in the Escrow Funds at any time or times (including without limitation with respect to the exercise of any voting or consent rights, conversion or exchange rights, defense of title, preservation of rights against prior matters or otherwise). Notwithstanding the foregoing, upon the Stockholder Representative's written request received by the Escrow Agent at least three (3) business days in advance, the Escrow Agent shall execute or cause its nominee to execute, and deliver to the Stockholder Representative a proxy or other instrument in the form supplied to it by the Stockholder Representative for voting or otherwise exercising any right of consent with respect to any of the Escrow Shares held by it hereunder, to authorize therein the Stockholder Representative to exercise such voting or consent authority in respect of the Escrow Shares (provided that the Escrow Agent shall not be obliged to execute any such proxy or other instrument if, in its judgment, the terms thereof may subject the Escrow Agent to any liabilities or obligations in its individual capacity). The Escrow Agent shall not be under any duty or responsibility to forward to any stockholders, or to notify any stockholders with respect to, or to take any action with respect to, any notice, solicitation or other document or information, written or otherwise, received from an issuer or other person with respect to the Escrow Shares or Parent Preferred Escrow Shares, including but not limited to, proxy material, tenders, options, the pendency of calls and maturities and expiration of rights. I. Notwithstanding any term herein to the contrary, the Escrow Agent (i) shall be obligated only for the performance of such duties as are expressly and specifically set forth in this Agreement on its part to be performed, each of which is ministerial (and shall not be construed to be fiduciary) in nature, and no implied duties or obligations of any kind shall be read into this Agreement against or on the part of the Escrow Agent, and (ii) shall not be obligated to take any legal or other action hereunder which might in its judgment involve or cause it to incur any expense or liability unless it shall have been furnished with acceptable indemnification. J. In no event shall the Escrow Agent be liable for indirect, punitive, special or consequential damage or loss (including but not limited to lost profits) whatsoever, even if the Escrow Agent has been informed of the likelihood of such loss or damage and regardless of the form of action. K. The Escrow Agent shall have no more or less responsibility or liability on account of any action or omission of any book-entry depository, securities intermediary, clearing agent or transfer agent than any such book-entry depository, securities intermediary or other agent has to the Escrow Agent, except to the extent that such action or omission of any book-entry depository, securities intermediary or agent was caused by the Escrow Agent's own gross negligence or willful misconduct in breach of this Agreement. L. Notwithstanding anything herein to the contrary, at any time that the Escrow Agent is authorized or directed or otherwise required to make a disbursement or distribution from the Escrow Funds, or from proceeds thereof, as applicable, the Escrow Agent, without liability, may refrain from making such disbursement or distribution if and to the extent that there are any amounts then due or owing to the Escrow Agent under or pursuant to this Agreement by the recipient of such proposed distribution. Upon receipt of payment for such amounts, the Escrow Agent shall promptly make such disbursement or distributions notwithstanding the Escrow Agent's receipt, if any, of a Notice after the date on which such distribution or disbursement otherwise would have been made if the Escrow Agent had not exercised its right to withhold pursuant to the preceding sentence. C-13 157 M. It is understood and agreed that, should any dispute arise with respect to the delivery, ownership, right of possession, and/or disposition of the Escrow Funds, or should any claim be made upon the Escrow Agent or the Escrow Funds by a third party, the Escrow Agent upon receipt of notice of such dispute or claim is authorized and shall be entitled (at its sole option and election) to retain in its possession without liability to anyone, all or any of said Escrow Funds until such dispute shall have been settled either by the mutual written agreement of the parties involved or by a final order, decree or judgment of a court in the United States of America, the time for perfection of an appeal of such order, decree or judgment having expired. The Escrow Agent may, but shall be under no duty whatsoever to, institute or defend any legal proceedings which relate to the Escrow Funds. N. The Escrow Agent shall not be responsible for delays or failures in performance resulting from acts beyond its control. Such acts shall include but not be limited to acts of God, strikes, lockouts, riots, acts of war, epidemics, governmental regulations superimposed after the fact, fire, communication line failures, computer viruses, power failures, earthquakes or other disasters. O. This Agreement and all documents relating thereto, including, without limitation, (a) consents, waivers and modifications which may hereafter be executed, and (b) certificates and other information previously or hereafter furnished, may be reproduced by any photographic, photostatic, microfilm, optical disk, micro-card, miniature photographic or other similar process. The parties agree that any such reproduction shall be admissible in evidence as the original itself in any judicial or administrative proceeding, whether or not the original is in existence and whether or not such reproduction was made by a party in the regular course of business, and that any enlargement, facsimile or further reproduction of such reproduction shall likewise be admissible in evidence. P. Unless the context expressly requires otherwise, any distribution to stockholders under this Agreement shall be made pro rata based upon (i) in the case of Escrow Shares, each stockholder's proportionate amount of ownership of Escrow Shares reflected on Exhibit A, or (ii) in the case of Parent Preferred Escrow Shares, each stockholder's proportionate amount of ownership of Parent Preferred Escrow Shares reflected on Exhibit A; in each case based upon Exhibit A as most recently amended, as of the date of such distribution. Q. Whenever this Agreement calls for distribution of Escrow Shares, such distribution shall be made, unless otherwise expressly provided herein, by the Escrow Agent (or its nominee) making delivery of the certificate or certificates representing such Escrow Shares to Cabletron, with appropriate instruction for the transfer and delivery of such shares (together with an appropriate executed stock power, if necessary). R. In no instance shall the Escrow Agent be responsible or liable for any actions, omissions or delays on the part of Cabletron (including, without limitation, with respect to any redemption, conversion, transfer or delivery of shares), the Stockholder Representative, the Company or other person or entity, including without limitation with respect to any failure by any of the foregoing to comply with the terms of this Agreement (or any agreement referred to herein). S. Any reference in this Agreement to "days" shall mean calendar days, unless otherwise specifically stated. C-14 158 IN WITNESS WHEREOF, the parties hereto have duly signed this Escrow Agreement as of the day and year first above written.

State of Residence: ----------------------------------------- E-7 177 ANNEX F December 5, 2000 Board of Directors Indus River Networks, Inc. 31 Nagog Park Acton, MA 01720 Dear Sirs: On August 14, 2000, Adams, Harkness & Hill, Inc. ("AH&H") was engaged by Indus River Networks, Inc. (together with its subsidiaries and affiliates, the "Client") to provide certain investment banking services in connection with the transaction (the "Transaction") contemplated by that certain Agreement and Plan of Merger, dated as of August 18, 2000 (the "Merger Agreement"), by and among Client, Cabletron Systems, Inc. ("Cabletron"), and Acton Acquisition Co., a wholly-owned subsidiary of Cabletron ("Merger Sub"). Pursuant to the terms of the Merger Agreement, Client's shareholders shall receive, in consideration of all of the outstanding capital stock of Client, aggregate consideration comprising four million (4,000,000) shares of common stock, par value $.01, of Cabletron ("Cabletron Common Stock") and fifty thousand (50,000) shares of Series C Convertible Preferred Stock, par value $1.00, of Cabletron ("Series C Preferred Stock"). AH&H has been engaged by Client to provide its Board of Directors (the "Board") with an appraisal of the value of the shares of Series C Preferred Stock to be issued by Cabletron as of five (5) trading days prior to the consummation of the Transaction (the "Appraisal"). Client has also engaged AH&H to provide the Board with a preliminary appraisal of the value of the Series C Preferred Stock (the "Preliminary Appraisal") for the sole purpose of including in the proxy statement/prospectus filed in connection with the Transaction an illustration of the valuation methodologies to be used by AH&H in delivering its Appraisal. AH&H, as part of its investment banking activities, is continually engaged in the valuation of businesses and their securities in connection with mergers and acquisitions, negotiated underwritings, secondary distributions of listed and unlisted securities, private placements and valuations for corporate and other purposes. In the course of our analysis and valuation, we used publicly available financial and other information regarding Cabletron and, in particular, its Enterasys Networks operating division ("Enterasys"), which we assumed to be reliable. Our conclusion is based on the assumption that such information is complete and accurate in all material respects. In addition to the publicly available information mentioned above, the principal sources of information upon which we relied in performing our valuation included, but were not limited to, the following: - Interviews with certain members of the management teams of Client, Cabletron, and Enterasys respectively; - publicly available information regarding certain companies comparable to Enterasys; - documentation and other materials and information regarding the Transaction and the Series C Preferred Stock; and - such other information and analyses as we deemed necessary or appropriate in order to determine the fair market value of the Series C Preferred Stock. Our valuation methodology included, but was not limited to: (i) an analysis of the terms of the Series C Preferred Stock; (ii) an analysis of Cabletron's current and projected operating model; (iii) an analysis of Enterasys' current and projected operating model; (iv) a discounted cash flow valuation analysis of Enterasys; and (v) a comparable company valuation analysis of Enterasys. Based on the foregoing analyses and valuation methodologies, it is our conclusion that, for purposes of this Preliminary Appraisal, the aggregate fair market value as of December 4, 2000 of the 50,000 shares of Series C Preferred Stock is $24.32 million, or $486.40 per share. F-1 178 This Preliminary Appraisal is limited to the fair market value of the Series C Preferred Stock as of December 4, 2000. We are expressing no opinion as to the fairness, from a financial point of view or otherwise, of the consideration to be received by the shareholders of Client in the Transaction, nor are we expressing any opinion as to the value of the Cabletron Common Stock. Moreover, this Preliminary Appraisal does not constitute a recommendation to any shareholder of Client as to how such shareholder should vote with respect to the Transaction. In reaching our conclusions regarding the valuation expressed herein, we assume there are no hidden or unexpected conditions that could affect the value of Cabletron or Enterasys and accept no responsibility for discovering such conditions. We expect that the types of information analyzed and the valuation methodologies used by us in delivering the Appraisal will be similar to those used in delivering this Preliminary Appraisal. However, the valuation determined in the Appraisal may be materially different from the valuation set forth in this Preliminary Appraisal. This Preliminary Appraisal is rendered on the basis of securities market conditions prevailing as of December 4, 2000 and on the conditions and prospects, financial and otherwise, of Cabletron and Enterasys as known to us on December 4, 2000. We have not conducted, nor have we received copies of, any independent valuation or appraisal of any of the assets of Cabletron or Enterasys. This Preliminary Appraisal has been prepared in accordance with and subject to the engagement letter between AH&H and Client, dated August 14, 2000, and is intended for the use of Client solely for the purpose stated herein and may not be used for any other purpose without our prior written consent, except that this letter may be included in its entirety in any filing made by Cabletron and Client with the Securities and Exchange Commission with respect to the Transaction contemplated by the Merger Agreement.

INDEMNIFICATION OF DIRECTORS AND OFFICERS. Section 145 of the Delaware General Corporation Law, as amended, provides that a corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal or investigative (other than an action by or in the right of the corporation) by reason of the fact that he is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding if such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe such person's conduct was unlawful. Section 145 further provides that a corporation similarly may indemnify any such person serving in any such capacity who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor, against expenses actually and reasonably incurred in connection with the defense or settlement of such action or suit if such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interest of the corporation and except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that the Delaware Court of Chancery or such other court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Court of Chancery or such other court shall deem proper. Section 102(b)(7) of the Delaware General Corporation Law, as amended, permits a corporation to include in its certificate of incorporation a provision eliminating or limiting the personal liability of a director to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, provided that such provision shall not eliminate or limit the liability of a director (i) for any breach of the director's duty of loyalty to the corporation or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) under Section 174 of the Delaware General Corporation Law (relating to unlawful payment of dividends and unlawful stock purchase and redemption) or (iv) for any transaction from which the director derived an improper personal benefit. The registrant's Restated Certificate of Incorporation provides that the registrant's directors shall not be liable to the registrant or its stockholders for monetary damages for breach of fiduciary duty as a director, except to the extent that exculpation from liabilities is not permitted under the Delaware General Corporation Law as in effect at the time such liability is determined. The Restated Certificate of Incorporation further provides that the registrant shall indemnify its directors and officers to the full extent permitted by the law of the State of Delaware.

--------------- * Previously filed. II-3 182 ITEM 22. UNDERTAKINGS. (1) The undersigned registrant hereby undertakes: (i) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement: (a) To include any prospectus required by section 10(a)(3) of the Securities Act of 1933; (b) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20% change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement. (c) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement; (ii) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (iii) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering. (2) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (3) The undersigned registrant hereby undertakes that prior to any public reoffering of the securities registered hereunder through use of a prospectus which is a part of this registration statement, by any person or party who is deemed to be an underwriter within the meaning of Rule 145(c), the registrant undertakes that such reoffering prospectus will contain the information called for by the applicable registration form with respect to reofferings by persons who may be deemed underwriters, in addition to the information called for by the other items of the applicable form. (4) The registrant undertakes that every prospectus (i) that is filed pursuant to the immediately preceding paragraph, or (ii) that purports to meet the requirements of Section 10(a)(3) of the Securities Act and is used in connection with an offering of securities subject to Rule 415, will be filed as a part of an amendment to the registration statement and will not be used until such amendment is effective, and that, for purposes of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (5) That insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforce- II-4 183 able. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy s expressed in the Securities Act and will be governed by the final adjudication of such issue. (6) The undersigned registrant hereby undertakes to respond to requests for information that is incorporated by reference into the prospectus pursuant to Item 4, 10(b), 11, or 13 of this form, within one business day of receipt of such request, and to send the incorporated documents by first class mail or other equally prompt means. This includes information contained in documents filed subsequent to the effective date of the registration statement through the date of responding to the request. (7) The undersigned registrant hereby undertakes to supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in the registration statement when it became effective.
