EXHIBIT 10(d) RESTATED AND AMENDED NOTE PURCHASE AGREEMENT BETWEEN THE COMPANY AND AETHERWORKS CORPORATION DATED JUNE 19, 1996 AETHERWORKS CORPORATION RESTATED AND AMENDED NOTE PURCHASE AGREEMENT THIS RESTATED AND AMENDED AGREEMENT is made and entered into as of June 19, 1996, by and between AetherWorks Corporation, a Minnesota corporation (the "Company"), and Digi International Inc., a Delaware corporation ("Digi"), sometimes referred to individually as a "Party" and collectively as the "Parties." R E C I T A L S As of October 10, 1995, the Company and Digi executed a Note Purchase Agreement (the "1995 Note Purchase Agreement"), pursuant to which Digi purchased, and the Company issued, a convertible secured promissory note, dated October 10, 1995, in the original principal amount of $3,353,235 (the "1995 Convertible Note"). Digi also committed in the 1995 Note Purchase Agreement to purchase an additional convertible secured promissory note in the original principal amount of $1,433,290. Digi has held two seats on the Company's Board of Directors (the "Board of Directors" or the "Board") since October 10, 1995, and has participated in the decisions of the Board, including the election of the fifth member of the Board, the appointment of senior management of the Company, and Board-level decisions regarding the development of the ARMs and Jeeves, and the decision to acquire and develop V.Mach Technology (as hereinafter defined), which was not contemplated at the time of execution of the 1995 Note Purchase Agreement. Digi has expressed interest in purchasing, and the Company desires to have Digi purchase, in part for the development and commercial exploitation of V.Mach Technology, convertible promissory notes of the Company, in the aggregate principal amount of $9,000,000, in addition to one for $1,433,290 originally to be issued pursuant to the 1995 Note Purchase Agreement and the 1995 Convertible Note previously issued pursuant to the 1995 Note Purchase Agreement. In light of the mutual commercial opportunity presented by the V.Mach Technology, in recognition of the greater familiarity and closer relationship of the Parties and in order to provide for the additional development contemplated by the Parties, the Parties desire to amend and restate in its entirety the 1995 Note Purchase Agreement, most particularly to eliminate milestones set forth in the 1995 Note Purchase Agreement and the rights and obligations of the Parties in connection with such milestones, and to delineate the Parties' respective rights and obligations with respect to the V.Mach Technology. A G R E E M E N T NOW, THEREFORE, in consideration of the foregoing premises and the Parties' respective rights and obligations set forth in this Agreement, the Company and Digi hereby agree as follows: 1. AMENDMENT TO 1995 NOTE PURCHASE AGREEMENT AND COROLLARY DOCUMENTS. The 1995 Note Purchase Agreement shall be, and hereby is, amended and restated in its entirety by this Agreement. The 1995 Convertible Note shall be restated and amended in the form attached to this Agreement as Exhibit 1 upon execution of such form (and, as restated and amended, shall for purposes of this Agreement hereinafter be referred to as the "Amended 1995 Note"). Each of the Security Agreement, Manufacturing Agreement and Shareholder Voting Agreement issued pursuant to the 1995 Note Purchase Agreement shall be amended and restated in its entirety in the forms attached to this Agreement as Exhibits 3, 4 and 5, respectively, upon execution of such forms (and, as restated and amended in their entirety, shall, for purposes of this Agreement, hereinafter be referred to as the "Security Agreement," "Manufacturing Agreement" and "Shareholder Voting Agreement," respectively). Each of this Agreement, the Amended 1995 Note, the Notes to be issued under this Agreement, the Security Agreement, the Manufacturing Agreement, the Technology Transfer Agreement and the Shareholder Voting Agreement may be referred to individually a "Transaction Document" and collectively, as the "Transaction Documents".

The shares of Common Stock into which the Notes are convertible and all shares of Common Stock of the Company issued in exchange or substitution therefor are hereinafter sometimes referred to as the "Conversion Stock." Each Note shall be secured by a lien on those assets identified in, and in accordance with the terms of the Security Agreement. Each Note shall be due and payable on December 31, 1998.

Digi further understands that the Notes and Conversion Stock may not be transferred or resold without (a) registration under the Securities Act and any applicable state securities laws, or (b) an exemption from the requirements of the Securities Act and applicable state securities laws.

The Company will deliver to Digi: (a) as soon as practicable, but in any event within 30 days after the close of each month, unaudited consolidated balance sheets of the Company as of the end of such month, together with the related consolidated statements of operations and cash flow for such month, all in reasonable detail and certified by the principal accounting officer of the Company; and (b) as soon as practicable, but in any event within 90 days after the end of each fiscal year, a consolidated balance sheet of the Company as of the end of such fiscal year, together with the related consolidated statements of operations, shareholders' equity and cash flow for such fiscal year, all in reasonable detail and duly certified by the Company's independent public accountants, which accountants shall have given the Company an opinion, unqualified as to the scope of the audit, regarding such statements, provided that the audit may contain a qualification regarding the Company's ability to continue as a going concern or any other generally accepted qualifications for a similar ongoing concern; and (c) concurrently with the delivery in each year of the financial statements referred -11- to in paragraph (b) of this Section 7.3, a statement and report signed by the independent public accountants who certified such financial statements to the effect that they have read this Agreement and that in the course of the audit upon which their certificate was based they became aware of no condition or event which constituted an Event of Default of the Company (as hereinafter defined) or which, after notice or lapse of time or both, would constitute an Event of Default of the Company or if such accountants did become aware of any such condition or event, specifying the nature and period of existence thereof.

The Company will: (a) pay and discharge promptly, or cause to be paid and discharged promptly when due and payable, all taxes, assessments and governmental charges or levies imposed upon it or upon its income or upon any of its properties, as well as all material claims of any kind (including claims for labor, material and supplies) which, if unpaid, might by law become a lien or charge upon its property; provided, however, that the Company shall not be required to pay any such tax, assessment, charge, levy or claim if the amount, applicability or validity thereof shall currently be contested in good faith by appropriate proceedings and if the Company shall have set aside on its books reserves (segregated to the extent required by generally accepted accounting principles) deemed adequate by it with respect thereto; and (b) maintain and keep, or cause to be maintained and kept, its properties in good repair, working order and condition, and from time to time make, or cause to be made, all repairs and renewals and replacements which in the opinion of the Company are necessary and proper so that the business carried on in connection therewith may be properly and advantageously conducted at all times; the Company will maintain or cause to be maintained back-up copies of all valuable papers and software. 7.6 INSURANCE. The Company will obtain and maintain in force such property damage, public liability, business interruption, worker's compensation, indemnity bonds and other types of insurance as the Company's executive officers, after consultation with an accredited insurance broker, shall determine to be necessary or appropriate to protect the Company from the insurable hazards or risks associated with the conduct of the Company's business. The Company's executive officers shall periodically report to the Board of Directors on the status of such insurance coverage. All insurance shall be maintained in at least such amounts and to such extent as shall be determined to be reasonable by the Board of Directors; and all such insurance shall be effected and maintained in force under a policy or -12- policies issued by insurers of recognized responsibility, except that the Company may effect worker's compensation or similar insurance in respect of operations in any state or other jurisdiction either through an insurance fund operated by such state or other jurisdiction or by causing to be maintained a system or systems of self-insurance which is in accord with applicable laws. 7.7 PAYMENT OF INDEBTEDNESS AND DISCHARGE OF OBLIGATIONS. The Company will pay or cause to be paid the principal of and interest and premium, if any, on all indebtedness for borrowed money heretofore or hereafter incurred or assumed by it when and as the same shall become due and payable, unless such indebtedness for borrowed money is renewed or extended, except in the case of the existing notes the holders of which will be offered the right to convert the indebtedness evidenced thereby to Common Stock pursuant to the terms of the Private Placement Memorandum previously approved by the Company's Board of Directors. The Company will faithfully observe, perform and discharge all of the material covenants, conditions and obligations which are imposed on it by any and all indentures and other agreements securing or evidencing such indebtedness for borrowed money or pursuant to which such indebtedness for borrowed money is issued, and will not permit the continuance of any act or omission which is or under the provisions thereof may be declared to be a material default thereunder, unless such default is waived pursuant to the provisions thereof. The Company shall not be required to make any payment or to take any other action by reason of this Section 7.7 at any time while it shall be currently contesting in good faith by appropriate proceedings its obligations to make such payment or to take such action provided that the Company shall have set aside on its books reserves (segregated to the extent required by generally accepted accounting principles) deemed adequate by it with respect thereto. For purposes of this Section 7.7, the phrase "indebtedness for borrowed money" shall have the meaning ascribed to it pursuant to Section 5.13 of this Agreement. 7.8 DIRECTORS' AND SHAREHOLDERS' MEETINGS. Until the earliest to occur of (i) repayment in full of the Notes if the Notes are not converted, or (ii) the date of the Company's Initial Public Offering, the Company shall have a Board of Directors the composition of which shall be determined as follows: (a) so long as it is the holder of any Notes or Conversion Stock, Digi shall be entitled to designate two fifths (2/5) of the directors of the Company and to exercise any right of removal or replacement of any such director, (b) the holders of a majority of the outstanding Common Stock exclusive of Digi shall be entitled to designate two fifths (2/5) of the directors of the Company and to exercise any right of removal or replacement of any such director, (c) the remaining director or directors must be approved by both Digi and by the holders of a majority of the outstanding Common Stock exclusive of Digi and shall be a person (or persons) who is (are) not otherwise affiliated with the Company or Digi or any officer or other director of the Company or Digi, and (e) Digi and the Company agree that in submitting to the Company's shareholders or Board of Directors the names of nominees for election as directors or in filling interim vacancies, each will use its best efforts to cause any person designated pursuant to this Section 7.8 to be elected as a director. Failure of any of the persons so designated by the Company or Digi to be so elected shall be an Event of Default of the Company or an Event of Default of Digi respectively within the meaning of Section 11 hereof. The Company shall reimburse all directors elected for the reasonable out-of-pocket expenses incurred by them pursuant to this Section 7.8 in connection with the attending of meetings by their director designee or carrying out any other duties by such director designee that may be specified by the Board of Directors; shall maintain at all times, director and officer liability insurance in an amount of not less than $1 million from a carrier reasonably acceptable to the Board of Directors of the Company; and shall maintain as part of its Articles of Incorporation or Bylaws a provision for the indemnification of its directors to the full extent permitted by law. 7.9 RESERVATION OF SHARES; REPLACEMENT OF NOTES OR CERTIFICATES REPRESENTING CONVERSION STOCK. The Company shall at all times have authorized and reserved a sufficient number of -13- shares of its Common Stock for the purpose of issue upon the conversion of the Notes. Upon receipt of evidence reasonably satisfactory to the Company of the loss, theft, destruction or mutilation of any Notes or certificates representing Conversion Stock, and, in the case of any such loss, theft or destruction, upon delivery of a bond of indemnity satisfactory to the Company, or, in the case of any such mutilation, upon surrender and cancellation of the Notes or certificates representing Conversion Stock, as the case may be, the Company will issue new Notes or certificates representing Conversion Stock of like tenor, in lieu of such lost, stolen, destroyed or mutilated Notes or certificates representing Conversion Stock. 7.10 APPLICATION OF PROCEEDS. Unless otherwise approved by the Company's Board of Directors, the net proceeds received by the Company from the sale of the Notes shall be used to pay the existing payables and indebtedness, for general operating purposes, and for the development of the ARMs, Jeeves and V.Mach. Pending such use of the proceeds, they shall be deposited in a bank or banks having deposits of $150,000,000 or more, invested in money market mutual funds having assets of $500,000,000 or more, or invested in securities issued or guaranteed by the United States Government or the agencies or instrumentalities thereof. 7.11 RETIREMENT PLANS. The Company will cause each retirement plan of the Company in which any employees of the Company participate that is subject to the provisions of ERISA and the documents and instruments governing each such plan to be conformed to when necessary, and to be administered in a manner consistent with, those provisions of ERISA which may, from time to time, become effective and operative with respect to such plans; and at such time as such insurance shall be available at rates deemed commercially reasonable by the Company, maintain insurance against the contingent liability against the net worth of the Company imposed in respect of each such plan by the provisions of ERISA. 7.12 FILING OF REPORTS. The Company will, from and after such time as it has securities registered pursuant to Section 12 of the Securities Exchange Act of 1934, as amended, or has securities registered pursuant to the Securities Act, make timely filing of such reports as are required to be filed by it with the Commission so that Rule 144 under the Securities Act or any successor provision thereto will be available to the security holders of the Company who are otherwise able to take advantage of the provisions of such Rule. 7.13 PATENTS AND OTHER INTANGIBLE RIGHTS. The Company will apply for, or obtain assignments of, or licenses to use, all patents, trademarks, trademark rights, trade names, trade name rights and copyrights which in the opinion of a prudent and experienced businessperson operating in the industry in which the Company is operating are desirable or necessary for the conduct and protection of the business of the Company. 7.14 RULE 144A. The Company agrees that, upon Digi's request, the Company shall promptly provide (but in any case within 15 days of a request) to Digi the following information: (a) a brief statement of the nature of the business of the Company and the products and services it offers; (b) the Company's most recent consolidated balance sheets and profit and loss and retained earnings statements, and similar financial statements for such part of the two preceding fiscal years prior to such request as the Company has been in operation (such financial information shall be audited, to the extent reasonably available); and (c) such other information about the Company and its business, financial condition and results of operations as the requesting person shall specify in order to comply with Rule 144A promulgated under the Securities Act and the anti-fraud provisions of the federal and state securities laws. The Company hereby represents and warrants to any such requesting person that the information provided by the Company pursuant to this Section 7.14 will not contain any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements made, in light of the -14- circumstances under which they were made, not misleading. 8. NEGATIVE COVENANTS. Subject to the provisions of Section 13 hereof, the Company will be limited and restricted as follows: 8.1 CONSOLIDATION, MERGER, ACQUISITION, ETC. Without the prior approval of Digi, (a) the Company will not sell, lease, license or otherwise dispose of all or substantially all of its assets or any asset or assets in a manner which would require shareholder approval, and (b) the Company will not consolidate with or merge into any other corporation or entity, or permit any other corporation or entity to consolidate or merge into the Company, or enter into a plan of exchange with any other corporation or entity, or otherwise acquire any other corporation or entity; provided that the foregoing shall not apply to any transaction between the Company and a wholly-owned subsidiary. 8.2 DIVIDENDS ON OR REDEMPTION OF CAPITAL STOCK. Without the prior approval of Digi, which approval shall not be unreasonably withheld, the Company will not declare or pay any dividend or make any other distribution on any shares of capital stock or purchase, redeem or otherwise acquire for any consideration, or set aside a sinking fund or other fund for the redemption or repurchase of any shares of capital stock or any warrants, rights or options to purchase shares of capital stock. 8.3 ISSUANCE OF SECURITIES. Except as provided in the Disclosure Schedules, as disclosed to the Company's Board of Directors prior to the date of this Agreement or pursuant to a stock option plan approved by the Company's Board of Directors, the Company will not, without the prior approval of Digi, issue (i) any additional capital stock of the Company of any class, or securities convertible into any such class, or (ii) any options, warrants or other rights to purchase capital stock of the Company of any class, or securities convertible into shares of any such class. 8.4 CHANGE IN THE NATURE OF THE COMPANY'S BUSINESS.

Except for any registration expressly permitted by Section 10 hereof, the Company will not, without the prior approval of the Company's Board of Directors, agree with the holders of any securities issued or to be issued by the Company to register such securities under the Securities Act nor will it grant any incidental registration rights. 8.6 OTHER RESTRICTIONS. The Company will not without the prior approval of the Company's Board of Directors: (a) guarantee, endorse or otherwise be or become contingently liable in connection with the obligations, securities or dividends of any person, firm, association or corporation, other than endorse negotiable instruments for collection in the ordinary course of business; or (b) make loans or advances to any person (including without limitation to any officer, director or shareholder of the Company), firm, association or corporation, except loans and advances to the Company and advances to suppliers and employees made in the ordinary course of business; or (c) purchase or invest in the stock or obligations of any other person, firm or corporation; or (d) pay compensation, whether by way of salaries, bonuses, participations in -15- pension or profit sharing plans, fees under management contracts or for professional services or fringe benefits to any officer in excess of amounts fixed by the Board of Directors of the Company prior to any payment to such officer. 9. RESTRICTION ON TRANSFER OF SECURITIES. 9.1 RESTRICTIONS. The Notes and the Conversion Stock are transferable only pursuant to (a) a public offering registered under the Securities Act, (b) Rule 144 (or any similar rule then in effect) adopted under the Securities Act, if such rule is available, and (c) subject to the conditions elsewhere specified in this Section 9, any other legally available means of transfer. 9.2 LEGEND. Each Note shall be endorsed with the following legend: "The securities evidenced hereby may not be transferred without (i) the opinion of counsel satisfactory to the Company that such transfer may be lawfully made without registration under the Federal Securities Act of 1933 and all applicable state securities laws or (ii) such registration." Upon the conversion of any Notes, unless the Company receives an opinion of counsel from Digi satisfactory to the Company to the effect that a sale, transfer, assignment, pledge or distribution of the Conversion Stock issuable upon such conversion may be made without registration, or unless such Conversion Stock is being disposed of pursuant to registration under the Securities Act and any applicable state act, the same legend shall be endorsed on the certificate evidencing such Conversion Stock. 9.3 STOP TRANSFER ORDER. A stop transfer order shall be placed with the Company's transfer agent preventing transfer of any of the securities subject to the legend referred to in Section 9.2 above pending compliance with the conditions set forth in any such legend. 9.4 REMOVAL OF LEGEND. Any legend endorsed on a certificate or instrument evidencing a security pursuant to Section 9.2 hereof shall be removed, and the Company shall issue a certificate or instrument without such legend to Digi, if such security is being disposed of pursuant to registration under the Securities Act and any applicable state acts or pursuant to Rule 144 or any similar rule then in effect, or if Digi provides the Company with an opinion of counsel satisfactory to the Company to the effect that a sale, transfer, assignment, offer, pledge or distribution for value of such security may be made without registration and that such legend is not required to satisfy the applicable exemption from registration. 10. REGISTRATION OF SECURITIES. 10.1 DIGI DEMAND FOR REGISTRATION. If the Company shall receive a written request therefor from Digi, the Company shall prepare and file a registration statement under the Securities Act covering the Conversion Stock which is the subject of such request and shall use its best efforts to cause such registration statement to become effective; provided, however, Digi may not make such a request prior to the expiration of six (6) months from the date of this Agreement. In addition, if the registration requested by Digi would result in the Company's first registration of securities under the Securities Act, the Company shall have the right to defer filing such registration for a period of not more than twelve (12) months after the Company's receipt of Digi's request. The Company shall be obligated to prepare, file and cause to become effective only one registration statement (other than on Form S-3 or any successor form promulgated by the Commission ("Form S-3")) pursuant to this Section 10.1, and to pay the expenses associated with such registration statements; notwithstanding the foregoing, Digi may require, pursuant to this Section 10.1, the Company to file, and to pay the expenses associated with, any number of registration -16- statements on Form S-3, if such form is then available for use by the Company and such record holder or holders. In the event that Digi determines for any reason not to proceed with a registration at any time before a registration statement has been declared effective by the Commission, and such registration statement, if theretofore filed with the Commission, is withdrawn with respect to the Conversion Stock covered thereby, and Digi agrees to bear its own expenses incurred in connection therewith and to reimburse the Company for the expenses incurred by it attributable to the registration of such Conversion Stock, then Digi shall not be deemed to have exercised its right to require the Company to register Conversion Stock pursuant to this Section 10.1, provided, however, that in such event Digi may not exercise its deferral rights under Section 10.2 should the Company determine to continue with such a registration. If, at the time any written request for registration is received by the Company pursuant to this Section 10.1, the Company has determined to proceed with the actual preparation and filing of a registration statement under the Securities Act in connection with the proposed offer and sale for cash of any of its securities by it or any of its security holders, such written request shall be deemed to have been given pursuant to Section 10.2 hereof rather than this Section 10.1, and the rights of Digi covered by such written request shall be governed by Section 10.2 hereof. 10.2 INCIDENTAL REGISTRATION. Each time the Company shall determine to proceed with the actual preparation and filing of a registration statement under the Securities Act in connection with the proposed offer and sale for cash of any of its securities by it or any of its security holders (other than a registration statement on a form that does not permit the inclusion of shares by its security holders), the Company will give written notice of its determination to Digi. If the registration which is the subject of the notice to Digi by the Company would result in the Company's first registration of securities under the Securities Act, Digi shall have the right to defer filing such registration for a period of not more than twelve (12) months after Digi's receipt of the Company's notice. Upon the written request of Digi given within 30 days after receipt of any such notice from the Company, the Company will, except as herein provided, cause all Conversion Stock for which Digi has requested registration to be included in such registration statement, all to the extent requisite to permit the sale or other disposition by Digi of such Conversion Stock; provided, however, that nothing herein shall prevent the Company from, at any time, abandoning or delaying any such registration initiated by it; provided further, however, that if the Company determines not to proceed with a registration after the registration statement has been filed with the Commission and the Company's decision not to proceed is primarily based upon the anticipated public offering price of the securities to be sold by the Company, and if Digi so requests the Company shall promptly complete the registration for Digi's benefit and Digi shall bear all expenses in excess of $25,000 incurred by the Company as the result of such registration after the Company has decided not to proceed. If any registration pursuant to this Section 10.2 shall be underwritten in whole or in part, the Company may require that the Conversion Stock requested for inclusion pursuant to this Section 10.2 be included in the underwriting on the same terms and conditions as the securities otherwise being sold through the underwriters. In the event that the Conversion Stock requested for inclusion pursuant to this Section 10.2 would constitute more than 25% of the total number of shares to be included in a proposed underwritten public offering, and if in the good faith judgment of the managing underwriter of such public offering the inclusion of all of the Conversion Stock originally covered by a request for registration would reduce the number of shares to be offered by the Company or interfere with the successful marketing of the shares of stock offered by the Company, the number of Conversion Stock otherwise to be included in the underwritten public offering may be reduced. Conversion Stock which is thus excluded from the underwritten public offering shall be withheld from the market by Digi for a period not to exceed 90 days, which the managing underwriter reasonably determines is necessary in order to effect the underwritten public offering. 10.3 REGISTRATION PROCEDURES. If and whenever the Company is required by the -17- provisions of Section 10.1 or 10.2 hereof to effect the registration of Conversion Stock under the Securities Act, the Company will: (a) prepare and file with the Commission a registration statement with respect to such securities, and use its best efforts to cause such registration statement to become and remain effective for such period as may be reasonably necessary to effect the sale of such securities, not to exceed nine months; (b) prepare and file with the Commission such amendments to such registration statement and supplements to the prospectus contained therein as may be necessary to keep such registration statement effective for such period as may be reasonably necessary to effect the sale of such securities, not to exceed nine months; (c) furnish to Digi and to the underwriters of the securities being registered such reasonable number of copies of the registration statement, preliminary prospectus, final prospectus and such other documents as such underwriters may reasonably request in order to facilitate the public offering of such securities; (d) use its best efforts to register or qualify the securities covered by such registration statement under such state securities or blue sky laws of such jurisdictions as Digi may reasonably request in writing within 20 days following the original filing of such registration statement, except that the Company shall not for any purpose be required to execute a general consent to service of process or to qualify to do business as a foreign corporation in any jurisdiction wherein it is not so qualified; (e) notify Digi, promptly after it shall receive notice thereof, of the time when such registration statement has become effective or a supplement to any prospectus forming a part of such registration statement has been filed; (f) notify Digi promptly of any request by the Commission for the amending or supplementing of such registration statement or prospectus or for additional information; (g) prepare and file with the Commission, promptly upon the request of Digi, any amendments or supplements to such registration statement or prospectus which, in the opinion of counsel for Digi (and concurred in by counsel for the Company), is required under the Securities Act or the rules and regulations thereunder in connection with the distribution of the Conversion Stock by Digi; (h) prepare and promptly file with the Commission and promptly notify Digi of the filing of such amendment or supplement to such registration statement or prospectus as may be necessary to correct any statements or omissions if, at the time when a prospectus relating to such securities is required to be delivered under the Securities Act, any event shall have occurred as the result of which any such prospectus or any other prospectus as then in effect would include an untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances in which they were made, not misleading; (i) advise Digi, promptly after it shall receive notice or obtain knowledge thereof, of the issuance of any stop order by the Commission suspending the effectiveness of such registration statement or the initiation or threatening of any proceeding for that purpose and promptly use its best efforts to prevent the issuance of any stop order or to obtain its withdrawal if such stop order should be issued; -18- (j) not file any amendment or supplement to such registration statement or prospectus to which Digi shall have reasonably objected on the grounds that such amendment or supplement does not comply in all material respects with the requirements of the Securities Act or the rules and regulations thereunder, after having been furnished with a copy thereof at least five business days prior to the filing thereof, unless in the opinion of counsel for the Company the filing of such amendment or supplement is reasonably necessary to protect the Company from any liabilities under any applicable federal or state law and such filing will not violate applicable law; and (k) at the request of Digi, furnish: (i) an opinion, dated as of the closing date, of the counsel representing the Company for the purposes of such registration, addressed to the underwriters, if any, and to Digi, covering such matters as such underwriters and Digi may reasonably request; and (ii) letters dated as of the effective date of the registration statement and as of the closing date, from the independent certified public accountants of the Company, addressed to the underwriters, if any, and to Digi, covering such matters as such underwriters and Digi may reasonably request. 10.4 EXPENSES. With respect to each registration, including registrations pursuant to Form S-3, requested pursuant to Section 10.1 hereof (except as otherwise provided in such Section with respect to registrations voluntarily terminated at the request of Digi) and with respect to each inclusion of Conversion Stock in a registration statement pursuant to Section 10.2 hereof (except as otherwise provided in Section 10.2 with respect to registrations initiated by the Company but with respect to which the Company has determined not to proceed), the Company shall bear the following fees, costs and expenses: all registration, filing and NASD fees, printing expenses, fees and disbursements of counsel and accountants for the Company, fees and disbursements of counsel for the underwriter or underwriters of such securities (if the Company and/or Digi are required to bear such fees and disbursements), all internal Company expenses, all legal fees and disbursements and other expenses of complying with state securities or blue sky laws of any jurisdictions in which the securities to be offered are to be registered or qualified, and the premiums and other costs of policies of insurance against liability (if any) arising out of such public offering. Fees and disbursements of counsel and accountants for Digi, underwriting discounts and commissions and transfer taxes relating to the shares included in the offering by Digi, and any other expenses incurred by Digi not expressly included above, shall be borne by Digi. 10.5 INDEMNIFICATION. In the event that any Conversion Stock is included in a registration statement under Section 10.1 or 10.2 hereof: (a) The Company will indemnify and hold harmless Digi pursuant to the provisions of this Section 10, its directors and officers, and any underwriter (as defined in the Securities Act) for Digi and each person, if any, who controls Digi or such underwriter within the meaning of the Securities Act, from and against, and will reimburse Digi and each such underwriter and controlling person with respect to, any and all loss, damage, liability, cost and expense to which Digi or any such underwriter or controlling person may become subject under the Securities Act or otherwise, insofar as such losses, damages, liabilities, costs or expenses are caused by any untrue statement or alleged untrue statement of any material fact contained in such registration statement, any prospectus contained therein or any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances in which they were made, not misleading; provided, however, that the Company will not be liable in any such case to the extent that any such loss, damage, liability, cost or expense arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission so -19- made in conformity with information furnished by Digi, such underwriter or such controlling person in writing specifically for use in the preparation thereof. (b) Digi will indemnify and hold harmless the Company, its directors and officers, any controlling person and any underwriter from and against, and will reimburse the Company, its directors and officers, any controlling person and any underwriter with respect to, any and all loss, damage, liability, cost or expense to which the Company or any controlling person and/or any underwriter may become subject under the Securities Act or otherwise, insofar as such losses, damages, liabilities, costs or expenses are caused by any untrue or alleged untrue statement of any material fact contained in such registration statement, any prospectus contained therein or any amendment or supplement thereto, or arise out of or are based upon the omission or the alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances in which they were made, not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was so made in reliance upon and in strict conformity with written information furnished by Digi specifically for use in the preparation thereof. (c) Promptly after receipt by an indemnified party pursuant to the provisions of paragraph (a) or (b) of this Section 10.5 of notice of the commencement of any action involving the subject matter of the foregoing indemnity provisions such indemnified party will, if a claim thereof is to be made against the indemnifying party pursuant to the provisions of said paragraph (a) or (b), promptly notify the indemnifying party of the commencement thereof; but the omission to so notify the indemnifying party will not relieve it from any liability which it may have to any indemnified party otherwise than hereunder. In case such action is brought against any indemnified party and it notifies the indemnifying party of the commencement thereof, the indemnifying party shall have the right to participate in, and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party, provided, however, if the defendants in any action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, or if there is a conflict of interest which would prevent counsel for the indemnifying party from also representing the indemnified party, the indemnified party or parties shall have the right to select separate counsel to participate in the defense of such action on behalf of such indemnified party or parties. After notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party will not be liable to such indemnified party pursuant to the provisions of said paragraph (a) or (b) for any legal or other expense subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation, unless (i) the indemnified party shall have employed counsel in accordance with the proviso of the preceding sentence, (ii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after the notice of the commencement of the action, or (iii) the indemnifying party has authorized the employment of counsel for the indemnified party at the expense of the indemnifying party. 11.
