RECITALS A. The respective Boards of Directors of each of the Company, CAIS and Atcom have determined that it is in the best interests of their respective companies and shareholders that the Company and Atcom combine into a single company through the statutory merger of the Company with and into Atcom, with Atcom as the surviving corporation (the "Merger"). B. CAIS, as the sole shareholder of the Company, has approved this Agreement, the Merger and the transactions contemplated by this Agreement pursuant to action taken by unanimous written consent in accordance with the requirements of the General Corporation Law of the State of California ("CGCL") and the Articles of Incorporation and Bylaws of the Company. C. Pursuant to the Merger, among other things, the outstanding shares of Atcom Common Stock shall be exchanged for CAIS Common Stock and all options or warrants for the purchase of Atcom Common Stock shall become options or warrants for the purchase of CAIS Common Stock. D. The parties to the Agreement intend that the Merger qualify as a "merger," within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended (the "Code"), and that Atcom, the Company and CAIS will each be a "party to a reorganization," within the meaning of Section 368(b) of the Code, with respect to the Merger. E. Certain capitalized terms used in this Agreement are defined on Exhibit A. - --------- AGREEMENT In consideration of the agreements, provisions and covenants set forth below, Atcom, the Company and CAIS hereby agree as follows: 1 ARTICLE I. THE MERGER 1.1 The Merger. Subject to the terms and conditions of this Agreement, on the Effective Time (as defined below), the Company shall be merged with and into Atcom, Atcom shall be the surviving corporation (sometimes called the "Surviving Corporation") in such Merger and the separate existence of the Company shall thereupon cease. The Merger shall have the effects set forth in the CGCL. Without limiting the generality of the foregoing, on the Effective Time, all of the property, rights, privileges, powers and franchises of the Company and Atcom shall vest in the Surviving Corporation. 1.2 The Effective Time. The Merger shall become effective when a properly executed certificate or agreement of merger (the "Agreement of Merger"), in such form as may be agreed by the parties hereto and as required by the relevant provisions of the CGCL is duly filed with the Secretary of State of the State of California, which filing shall be made in connection with the closing of the Merger in accordance with Section 2.8 upon satisfaction or waiver of the conditions set forth in Articles VII and VIII. When used in this Agreement, the term "Effective Time" shall mean the date and time at which such Agreement of Merger has been so filed or at such later time as is provided in the Agreement of Merger. 1.3 The Surviving Corporation. (a) The Articles of Incorporation of the Company as in effect at the Effective Time shall be the Articles of Incorporation of the Surviving Corporation until duly amended in accordance with applicable law. (b) The Bylaws of the Company as in effect at the Effective Time shall be the Bylaws of the Surviving Corporation until thereafter amended in accordance with applicable law. (c) (i) The directors of the Company at the Effective Time shall be the initial directors of the Surviving Corporation and shall hold office from the Effective Time until their respective successors are duly elected or appointed and qualified in the manner provided in the Articles of Incorporation and Bylaws of the Surviving Corporation, or as otherwise provided by law. (ii) The officers of the Company at the Effective Time shall be the initial officers of the Surviving Corporation and shall hold office from the Effective Time until removed or until their respective successors are duly elected or appointed and qualified in the manner provided in the Articles of Incorporation and Bylaws of the Surviving Corporation, or as otherwise provided by law. 2 ARTICLE II. TREATMENT OF SHARES 2.1 Certain Definitions. (a) "Exchange Ratio" shall be equal to the quotient of (i) the Per Share Merger Consideration divided by (ii) the Average CAIS Stock Price as of August 2, 1999, or 0.3553. (b) "Per Share Merger Consideration" shall be equal to $6.0934. 2.2 Conversion of Shares. (a) At the Effective Time, by virtue of the Merger and without any action on the part of the holders thereof, and subject to Section 2.4, each ----------- share of Atcom Common Stock that is issued and outstanding immediately prior to the Effective Time (other than dissenting shares of such class and series) shall be converted into the right to receive the number of shares of CAIS Common Stock equal to the Exchange Ratio. (b) All Atcom stock options and warrants to purchase Atcom Common Stock (individually, an "Atcom Option" and collectively, the "Atcom Options") outstanding immediately prior to the Effective Time shall remain outstanding following the Effective Time. At the Effective Time, such Atcom Options shall, by virtue of the Merger and without any further action on the part of Atcom or the holder of any such Atcom Options, be assumed by CAIS. Each Atcom Option assumed by CAIS shall be exercisable upon the same terms and conditions as those pertaining to the option immediately prior to the Effective Time, except that in the case of an Atcom Option to purchase Atcom Common Stock (A) each such Atcom Option shall be exercisable for that whole number of shares of CAIS Common Stock (rounded down to the nearest whole share) into which the number of shares of Atcom Common Stock subject to such Atcom Option immediately prior to the Effective Time would be converted under this Section 2.2, and (B) the option price per share of CAIS Common Stock shall be an amount equal to the option price per share of Atcom Common Stock subject to such Atcom Option in effect immediately prior to the Effective Time divided by the Exchange Ratio (the price per share, as so determined, being rounded upward to the nearest full cent). Within 10 days after the Closing Date, CAIS shall notify each holder of an Atcom Option of the assumption of such options by CAIS and the revisions to the options effected thereby. No payment shall be made for fractional interests. From and after the date of this Agreement, no additional stock options or warrants shall be granted or issued by Atcom. (c) At the Effective Time, by virtue of the Merger and without any action on the part of the holder thereof, each share of the common stock of the Company that is issued and outstanding immediately prior to the Effective Time shall be converted into and continue as one share of the common stock of the Surviving Corporation. 3 2.3 Mechanics of Exchange. (a) At the Effective Time, each holder of Atcom Common Stock (each, a "Shareholder") shall be entitled to surrender the certificate or certificates that immediately prior to the Effective Time represented the Atcom Common Stock (the "Certificates"), and which were converted into the right to receive a portion of the Merger Price, to CAIS for cancellation in exchange for shares of CAIS Common Stock into which such Atcom shares have been converted by virtue of the Merger, less such Shareholder's pro rata portion of the Escrow Amount. It shall be a condition of payment that the Certificates so surrendered shall be properly endorsed or otherwise in proper form for transfer to CAIS. (b) From and after the Effective Time, there shall be no transfers on the stock transfer books of Atcom of Atcom Common Stock which were outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates formerly representing Atcom Common Stock are presented to the Surviving Corporation for payment, they shall be cancelled and exchanged for the shares of CAIS Common Stock into which the Atcom shares represented thereby were converted in the Merger. (c) At or prior to the Effective Time of the Merger, CAIS shall deliver irrevocably to the Escrow Agent shares of CAIS Common Stock in an aggregate amount equal to the Escrow Amount. (d) In the event that any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Shareholder claiming such Certificate to be lost, stolen or destroyed, CAIS will issue or cause to be issued certificates representing CAIS Common Stock in exchange for such lost, stolen or destroyed Certificate in accordance with the conversion ratio set forth in Section 2.2. When authorizing such issuance in exchange therefor, CAIS may, in its discretion and as a condition precedent to the issuance thereof, require such Shareholder to give CAIS a bond in such sum as it may direct as indemnity, or such other form of indemnity, as it shall direct, against any claim that may be made against CAIS with respect to the Certificate alleged to have been lost, stolen or destroyed. (e) If any certificate for CAIS Common Stock is to be issued in a name other than that in which the Certificate surrendered in exchange therefor is registered, it shall be a condition of such exchange that the person requesting such exchange shall (i) pay to CAIS any transfer or other taxes required by reason of the issuance of certificates for such securities in a name other than that of the registered holder of the Certificate surrendered, or (ii) establish to the satisfaction of CAIS that such tax has been paid or is not applicable. (f) Notwithstanding anything in this Agreement to the contrary, neither CAIS nor any other party hereto shall be liable to a holder of shares of Atcom Common Stock for any portion of the Merger Price, or dividend on shares of CAIS Common Stock issued as part of the Merger Price, or in accordance with Section 2.6 the cash payment for any fractional interests, delivered to a public official pursuant to applicable escheat laws following the passage of time specified therein. 4 2.4 Escrow. A total of 291,375 shares of CAIS Common Stock otherwise issuable to the Shareholders pursuant to Section 2.2 (the "Escrow Amount") shall be issued in the names of the Shareholders entitled thereto but shall be delivered to and held in escrow until April 15, 2000 (subject to any pending Claims which exist on such date) pursuant to an Escrow Agreement in the form attached hereto as Exhibit B (the "Escrow Agreement") to secure Claims by Indemnified Parties for - --------- indemnification pursuant to Article XI. Nothing in this Section 2.4 shall be construed as limiting the liability of the Shareholders under Section 10.8 to the amount of the Escrow Amount deposited into escrow. 2.5 Dividends; Transfer Taxes. No dividends that are declared on shares of CAIS Common Stock after the Effective Time (if any) will be paid to persons entitled to receive certificates representing shares of CAIS Common Stock until such Persons surrender their Certificates. Upon such surrender, there shall be paid to the Person in whose name the certificates representing such shares of CAIS Common Stock shall be issued any dividends which shall have become payable with respect to such shares of CAIS Common Stock between the Effective Time and the time of such surrender. In no event shall the person entitled to receive such dividends be entitled to receive interest on such dividends. 2.6 No Fractional Shares. No fraction of a share of CAIS Common Stock shall be issued in the Merger. In lieu of fractional shares, the Shareholders upon surrender of their Certificates as set forth in Section 2.3 shall be paid an amount in cash, without interest, rounded to the nearest cent, determined by multiplying the fractional interest to which such Shareholder would otherwise be entitled by the Average CAIS Stock Price as of August 2, 1999, or $17.16. 2.7 Closing of Atcom Transfer Books. At the Effective Time, the stock transfer books of Atcom shall be closed and no transfer of shares of Atcom Common Stock shall thereafter be made. If, after the Effective Time, Certificates are presented to the Surviving Corporation, they shall be canceled and exchanged for certificates representing shares of CAIS Common Stock and cash in accordance with the terms hereof. At and after the Effective Time, the holders of shares of Atcom Common Stock to be exchanged for shares of CAIS Common Stock pursuant to this Agreement shall cease to have any rights as shareholders of Atcom, except for the right to surrender such Certificates in exchange for shares of CAIS Common Stock as provided hereunder or such dissenters' rights as are provided under applicable law. 2.8 Closing. The closing of the transactions contemplated by this Agreement (the "Closing") shall take place at the offices of Morrison & Foerster LLP, 555 W. Fifth Street, Los Angeles, California 5 90013 at 9:00 a.m., local time, on September 15, 1999 (the "Closing Date"), or as soon thereafter as is reasonable practical; provided, however, that if all of --------- -------- the other conditions set forth in Articles VII and VIII hereof are not satisfied or waived at such date, the Closing Date shall be the business day following the day on which all such conditions have been satisfied or waived, or at such other date, time and place as CAIS and Atcom shall agree. 2.9 Supplementary Action. If, at any time after the Effective Time, any further assignments or assurances in law or any other things are necessary or desirable to vest or to perfect or confirm of record in the Surviving Corporation the title to any property or rights of Atcom, or otherwise to carry out the provisions of this Agreement, the officers and directors of the Surviving Corporation are hereby authorized and empowered on behalf of Atcom in the name of and on behalf of Atcom to execute and deliver any and all things necessary or proper to vest or to perfect or confirm title to such property or rights in the Surviving Corporation, and otherwise to carry out the purposes and provisions of this Agreement. 2.10 Dissenting Shares. (a) Notwithstanding any provisions of this Agreement to the contrary, any shares of Atcom Common Stock held by a Shareholder who has exercised such holder's dissenters' rights in accordance with applicable law and who, as of the Effective Time, has not effectively withdrawn or lost such dissenters' rights ("Dissenting Shares"), shall not be converted into or represent a right to receive the Merger Price, but the holder of the Dissenting Shares shall only be entitled to such rights as are granted by applicable law. (b) Notwithstanding the provisions of subsection (a) above, if any holder of Dissenting Shares shall effectively withdraw or lose (through the failure to perfect or otherwise) such holder's dissenters' rights under the CGCL, then, as of the Effective Time or the occurrence of such event, such holder's shares shall automatically be converted into and represent only the right to receive the Per Share Merger Consideration upon surrender of the applicable Certificate(s) as provided herein. (c) Atcom shall give CAIS and the Company (i) prompt written notice of any written demands for payment with respect to any shares of Atcom capital stock pursuant to dissenters' rights, and any withdrawals of such demands or losses of such rights, and any other instruments served pursuant to the CGCL, and (ii) the opportunity to participate in all negotiations and proceedings with respect to demands for dissenters' rights. Atcom shall not, except with the prior written consent of CAIS and the Company, voluntarily make any payment with respect to demands for dissenters' rights or offer to settle or settle any such demands. 2.11 Registration of Option Shares CAIS shall, within two (2) weeks after the Closing Date, file a Registration Statement on Form S-8 with the SEC covering the shares of CAIS Common Stock issued or issuable pursuant to options to purchase Atcom Common Stock assumed by CAIS under Section 2.2(b) hereof. 6 2.12 Contingent Consideration (a) CAIS shall pay, within two (2) business days after the completion of a Qualified Financing (as defined below), $1.8280 per share of additional consideration ("Per Share Contingent Consideration") in shares of CAIS Common Stock to the holders (at the Effective Time) of Atcom Common Stock and to the holders of CAIS Common Stock who acquired such shares of CAIS Common Stock pursuant to the exercise of Atcom Options after the Effective Time as provided in Section 2.12(b) and Atcom Options as provided in Section 2.12(c) if a Qualified Financing is completed on or before November 21, 1999 (such payment of Per Share Contingent Consideration shall, in the aggregate, be referred to herein as the "Contingent Consideration"). For purposes of this Section 2.12, a "Qualified Financing" shall mean any sale by CAIS of at least $10 million of its capital stock in a single transaction or a series of related transactions to a strategic partner or partners pursuant to the terms of that certain letter agreement between CAIS and Volpe Brown Whalen & Company the date hereof. (b) In order to effect the aforesaid payment of Contingent Consideration, CAIS shall issue to each holder of Atcom Common Stock immediately prior to the Effective Time and to each holder of CAIS Common Stock who acquired such shares of CAIS Common Stock pursuant to the exercise of an Atcom Option after the Effective Time that number of shares of CAIS Common Stock determined by multiplying each share of Atcom Common Stock owned immediately prior to the Effective Time by the Contingent Consideration Exchange Ratio, which shall be equal to the quotient of (i) the Per Share Contingent Consideration divided by (ii) the Average CAIS Stock Price as of the date of execution of the definitive agreement in respect of the Qualified Financing, and, in the case of shares of CAIS Common Stock acquired pursuant to the exercise of any Atcom Option, by multiplying (x) the quotient of (A) the CAIS Common Stock so acquired divided by (B) the Exchange Ratio, times (y) the Contingent Consideration Exchange Ratio. (c) Notwithstanding anything to the contrary in Section 2.2(b), if CAIS shall become obligated to pay the Contingent Consideration, each Atcom Option assumed by CAIS and outstanding on the date of completion of the Qualified Financing shall be readjusted to give effect to the Contingent Consideration by (i) changing the number of shares subject to such option by multiplying the "Adjusted Exchange Ratio" set forth below by the quotient of (W) the shares still subject to the option divided by (X) the Exchange Ratio, and (ii) changing the option price per share by dividing the product of (Y) the adjusted option price (determined pursuant to Section 2.2(b)(B)) multiplied by (Z) the Exchange Ratio, by the following "Adjusted Exchange Ratio" set forth below: Exchange Ratio + Contingent Consideration Exchange Ratio = Adjusted Exchange Ratio 2.13 Restricted Stock. The shares of CAIS Common Stock issued in connection with the Merger (including the shares issued as part of the additional consideration) will not be registered under the Securities Act, except as provided in the Registration Rights Agreement. Such shares may not be 7 transferred or resold thereafter, except in compliance with the terms of this Agreement and the other Transactional Agreements and following registration under the Securities Act or in reliance on an exemption from registration under the Securities Act.

Notwithstanding the preceding sentence, any claim for indemnification 43 regarding any covenant, agreement, representation or warranty sought under Section 10.2 shall survive the time at which such covenant, agreement, representation or warranty shall terminate pursuant to the preceding sentence, if notice of such claim for indemnification shall have been given to the party against whom such indemnity is sought prior to such time. The covenants, agreements, representations and warranties of each of Atcom, the Company and CAIS and the rights and remedies that may be exercised by any Indemnitee or Shareholder shall not be limited, diminished or otherwise affected by or as a result of any information that may have been provided, any investigation or examination that may have or be made by, or any Knowledge of, any Indemnitee or any other party on behalf of any Indemnitee, or any Shareholder or any other party on behalf of any Shareholder, except as otherwise contemplated herein. 10.2 Indemnification by Shareholders The Shareholders severally and not jointly agree that the Escrow Amount shall be available to the extent provided in this Article X and in the Escrow Agreement to compensate each of CAIS and, effective at and as of the Effective Time, without duplication, the Surviving Corporation and each of their respective subsidiaries and affiliates and each of their respective officers, directors and shareholders (other than the Shareholders) (each in its capacity as an indemnified party, an "Indemnitee") for any and all losses, liabilities, damages, judgments, rulings, assessments and any and all amounts paid in settlement of or related to any claim or litigation or amounts mutually agreed to by CAIS and the Shareholder Representative (collectively, "Actual Damages"), and any and all costs and expenses, interest, penalties, reasonable attorneys' fees and any and all other expenses incurred in investigating, preparing, and defending against any litigation, commenced or threatened, and any claim whatsoever (collectively "Litigation Damages," together with "Actual Damages," "Damages") (Damages in each case shall be net of the amount of any insurance proceeds, indemnity or contribution actually recovered by such Indemnitee and such Indemnitee shall use commercially reasonable efforts to recover such amounts), incurred by such Indemnitee as a result of, arising out of or incident to any of the following with respect to which a claim for indemnification is brought by an Indemnitee within the applicable survival period described in Section 10.1: (i) any breach of any representation or warranty of Atcom set forth herein or in any other Transactional Document, or in any certificate or other document delivered in connection herewith or therewith, or (ii) any breach by Atcom of any covenant, agreement, or obligation contained herein or in the Escrow Agreement, or in any certificate or other document delivered in connection herewith or therewith except to the extent waived in writing by CAIS. 10.3 Indemnification by CAIS and the Company Subject to Section 10.8, CAIS and the Company jointly and severally agree to compensate the Shareholders for any and all Damages (Damages in each case shall be net of the amount of any insurance proceeds, indemnity or contribution actually recovered by such Shareholder and such the Shareholder Representative shall use commercially reasonable efforts to recover such amounts), incurred by the Shareholders as a result of, arising out of or incident to any of the following with respect to which a claim for indemnification is brought by the Shareholder Representative within the applicable survival period described in Section 10.1 for: 44 (i) any breach of any representation or warranty of CAIS or the Company set forth herein or in any other Transactional Agreement to which they are a party, or in any certificate or other document delivered in connection herewith or therewith, or (ii) any breach by CAIS or the Company of any covenant, agreement, or obligation contained herein or in any other Transactional Agreement to which they are a party, or in any certificate or other document delivered in connection herewith in each case, except to the extent waived in writing by the Shareholder Representative; provided, however, that the obligations of CAIS and the Company under this Article X shall in no event exceed in the aggregate an amount equal to the Escrow Amount. 10.4 Third Person Claims Promptly after an Indemnitee or a Shareholder (an "Indemnified Party") has received notice of or has knowledge of any claim by a person not a party to this Agreement ("Third Person") or the commencement of any action or proceeding by a Third Person, the Indemnified Party shall, as a condition precedent to the claim with respect thereto being made under this Article X, give the Shareholder Representative or CAIS, as applicable, written notice of such claim or the commencement of such action or proceeding; provided, however that the failure to give such notice will not affect the Indemnified Parties' right to indemnification hereunder with respect to such claim, action or proceeding, except to the extent that the Shareholder, CAIS or the Company (each, an "Indemnifying Party") has been actually prejudiced as a result of such failure. If the Indemnifying Party notifies the Indemnified Party within 30 days from the receipt of the foregoing notice that it wishes to defend against the claim by the Third Person and if the estimated amount of the claim, together with all other claims made hereunder that have not been settled, is less than the remaining balance of the Escrow Amount, then the Indemnifying Party shall have the right to assume and control the defense of the claim by appropriate proceedings with counsel reasonably acceptable to the Indemnified Party. In the event that the Shareholders are the Indemnified Parties, the Shareholder Representative shall be entitled to reimbursement out of the Escrow Amount for such defense. The Indemnified Party may participate in the defense, at its sole expense, of any such claim for which the Indemnifying Party shall have assumed the defense pursuant to the preceding sentence, provided that counsel for the Indemnifying Party shall act as lead counsel in all matters pertaining to the defense or settlement of such claims, suit or proceedings. The Indemnified Party shall be entitled to indemnification under Sections 10.2 or 10.3 (subject to the limitations set forth in Section 10.6) for the reasonable fees and expenses of its counsel for any periods during which the Indemnifying Party has not assumed the defense of any claim. Whether or not the Indemnifying Party shall have assumed the defense of any claim, neither the Indemnified Party nor the Indemnifying Party shall make any settlement with respect to any such claim, suit or proceeding without the prior consent of the other, which consent shall not be unreasonably withheld or delayed. It is understood and agreed that in situations where failure to settle a claim expeditiously could have an adverse effect on the party wishing to settle, the failure of the party controlling the defense to act upon a request for consent to such settlement within ten business days of receipt of notice thereof shall be deemed to constitute consent to such settlement for purposes of this Article X. 45 10.5 Method of Payment Subject to Section 10.8, the Indemnitees shall be entitled to satisfy claims for indemnification pursuant to this Article X only from the Escrow Amount. To the extent that any Indemnitee is entitled to indemnification hereunder, the Escrow Amount shall be valued as provided in the Escrow Agreement. 10.6 Limitations Notwithstanding any other provision in this Article X, Indemnitees or the Shareholders, as applicable, shall not be entitled to indemnification until the aggregate Damages exceed $50,000 (the "Threshold"), at which point the Shareholders or Indemnitees, as applicable, shall be liable for the full amount of all such claims, including the Threshold. 10.7 Maximum Liability and Remedies Subject to Section 10.8, the rights of the Indemnitees to make claims upon the Escrow Amount in accordance with this Article X shall be the sole and exclusive remedy of the Indemnitees after the Effective Time for any damage, claim, cause of action or right of any nature arising out of or relating to this Agreement, the certificates or other documents executed or delivered in connection herewith (except as expressly provided in the Escrow Agreement) and no Shareholder, and no Person who is or was an optionholder, warrantholder, director, officer, employee or agent of Atcom prior to the Effective Time shall have any personal liability to CAIS or the Surviving Corporation after the Closing Date in connection with the Merger. 10.8 Exceptions to Limitations Notwithstanding anything to the contrary set forth in this Article X or in the Escrow Agreement, none of the provisions of this Article X or the Escrow Agreement shall in any manner limit the liability of CAIS, the Company, Shareholders, or any Person who is or was an optionholder, warrantholder, director, officer, employee or agent of Atcom or any of the foregoing prior to the Effective Time, with respect to (i) claims of fraud or (ii) any criminal matters. 10.9 Shareholder Representative (a) Each Shareholder irrevocably authorizes, directs and appoints Neil Senturia to act as sole and exclusive agent, attorney-in-fact and representative of such Person and such Person's heirs, representatives and successors to (i) take any and all actions (including without limitation executing and delivering any documents), incurring any costs and expenses for the account of the Shareholders and making any and all determinations which may be required or permitted to be taken by the Shareholders in connection with this Article X or the Escrow Agreement; and (ii) exercise such rights, power and authority as are incidental to the foregoing. Any actions, exercises of rights, power or authority and any decisions or determinations made by the Shareholder Representative shall be absolutely and irrevocably binding on each Shareholder as if 46 each such Person personally had taken such action, exercised such rights, power or authority or made such decision or determination in such Person's individual capacity. (b) With respect to the matters covered by or related to this Article X and the Escrow Agreement, (i) each Shareholder irrevocably relinquishes its right to act independently and other than through the Shareholder Representative with respect to such subject matter (except with respect to appointment of a successor Representative), and (ii) no Shareholder shall have any right to institute any suit, action or proceeding against Atcom, CAIS, the Company, the Surviving Corporation or the Escrow Agent with respect to any such matter, any such right being irrevocably and exclusively delegated to the Shareholder Representative. Without limiting the generality of the foregoing, any notice hereunder delivered to CAIS or an Indemnitee by a Shareholder other than through the Shareholder Representative shall be of no effect, and each notice delivered by CAIS or any other Indemnitee to the Shareholder Representative shall be effective as against each Shareholder; provided, that CAIS and the other -------- Indemnitees may elect at their sole discretion to give effect to any notice delivered by any Shareholder. (c) The Shareholder Representative may resign at any time upon thirty (30) days notice by submitting a written resignation to CAIS, with copies to all other Shareholders at their addresses on the stock books of Atcom. In the event of the death, physical or mental incapacity or resignation of the Shareholder Representative, the Shareholders shall promptly (and in any event within thirty (30) days of notice of such event) appoint a successor Shareholder Representative. ARTICLE XI. RESTRICTIONS ON CAIS COMMON STOCK 11.1 Restrictive Legend.
