(d) The term "underwriter," as used herein, does not include any Holder. 3. REGISTRATION RIGHTS. (a) If IVT proposes to register any shares of Common Stock for its own account under the Securities Act at any time or times after the Restricted Period and before December 31, 2002 for a public offering, other than an Exempt Offering, in the United States, of those shares for cash (each such public offering, other than an Exempt Offering, being an "Eligible Offering"), then, at each of those times, each then Holder will, subject to the terms and conditions hereof, be entitled to have such number of shares of that Holder's Registrable Common as that Holder may request in accordance with Section 3(c) registered under the Securities Act for disposition by means of the registration statement relating to that Eligible Offering. (b) In the case of each Eligible Offering, IVT will deliver to each then Holder a written notice of that offering (a "Registration Notice") at least 15 days prior to its filing with the SEC of the registration statement, or the amendment thereto, which includes the Red Herring Prospectus for that offering. IVT will briefly describe in each Registration Notice the Eligible Offering to which that notice relates and inform the addressee that it has 10 days within which to request to include shares of its Registrable Common in the registration statement for that offering. (c) Any Holder desiring to participate in any Eligible Offering must deliver to IVT within 10 days after the Holder receives the Registration Notice for that offering a written notice to that effect (a "Request Notice"), specifying the number of shares of the Holder's Registrable Common the Holder desires to have registered under the Securities Act for inclusion in that offering. Any Holder that does not deliver a Request Notice for an Eligible Offering within that 10-day period will be deemed to have waived its right to participate in that offering unless IVT agrees otherwise in writing. (d) Any holder that delivers a Request Notice relating to an Eligible Offering on a timely basis, or as otherwise agreed by IVT, pursuant to Section 3(c) (each such Holder being a "Requesting Holder") will be entitled to offer and sell shares of its Registrable Common in that offering on the terms and conditions on which IVT offers and sells shares of Common Stock in that offering if the Requesting Holder complies with the applicable provisions of Sections 4, 5 and 10; provided, however, that: (i) IVT may reserve to itself the right to be the exclusive grantor of any -4- underwriter's overallotment option; and (ii) the shares of Registrable Common any Requesting Holder will be entitled to offer and sell will be subject to reduction as provided in Section 3(e). (e) IVT will have the right to determine the aggregate size of each Eligible Offering and to limit the number of shares of Registrable Common to be included in that offering without reducing the number of shares of Common Stock to be offered by IVT in that offering, as follows: (i) if the lead managing underwriter selected by IVT for an Eligible Offering (or, if that offering will not be underwritten, a financial advisor to IVT) determines that marketing factors render necessary or advisable a limitation on the number of shares of Registrable Common to be included in that offering, IVT will be required to include in that offering only such number of shares of Registrable Common, if any, as that lead managing underwriter (or financial advisor, as the case may be) believes (as evidenced by its written advice to IVT) will not jeopardize the success of the primary offering by IVT; and (ii) if IVT limits the number of shares of Registrable Common that Requesting Holders may have included in any Eligible Offering pursuant to clause (i), but does not exclude all shares of Registrable Common from that offering, the maximum number of shares of Registrable Common to be included in that offering on behalf of each of those Requesting Holders will be the product of (A) the number of shares of Registrable Common that Requesting Holder has specified in its Request Notice relating to that offering multiplied by (B) the fraction the numerator of which is the number of shares of Registrable Common that Requesting Holder has specified in its Request Notice relating to that offering and the denominator of which is the aggregate number of shares of Registrable Common all those Requesting Holders have specified in their Request Notices relating to that offering. If IVT determines, on the basis of advice of its tax counsel or independent accountants, that the inclusion of a Requesting Holder's shares of Registrable Common in any Eligible Offering likely would jeopardize the nonrecognition status under the Internal Revenue Code of 1986, as amended, of any acquisition transaction effected by IVT, IVT will be entitled to limit the number of shares that Requesting Holder may have included in that offering to such number, if any, as IVT determines will not jeopardize that status. 4. REGISTRATION PROCEDURES. (a) Whenever IVT is required by Section 3 to include shares of Registrable Common in a registration statement relating to an Eligible Offering, it will, subject to the applicable terms and conditions hereof: (i) cause those shares to be registered under the Securities Act by means of a Seller's Registrable Statement, in either the original filing thereof or in a pre-effective amendment to a previously filed registration statement; (ii) prior to the first to occur of (A) the sale by the Holders thereof, by means of the Sellers' Registration Statement after it becomes effective under the Securities Act, of all the shares of Registrable Common covered by the Sellers' Registration Statement when it becomes effective under the Securities Act and the elapse of the period in which a dealer is required by the Securities Act to deliver a prospectus in connection with its offer and sale of any of those shares and (B) the withdrawal by IVT of the Sellers' Registration Statement pursuant to Securities Act Rule 477, prepare and file with the SEC under the Securities Act -5- such amendments (including post-effective amendments) to the Sellers' Registration Statement and supplements to the related prospectus as are necessary (A) to reflect the plan of distribution contemplated by the Sellers' Registration Statement and (B) so that (1) neither the Sellers' Registration Statement nor that prospectus contains any untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading and (2) both the Sellers' Registration Statement and that prospectus comply in all material respects with all other applicable legal requirements; (iii) provide to each Requesting Holder named as a selling stockholder in the Sellers' Registration Statement (each a "Selling Holder") such number of prospectuses (including preliminary prospectuses) and other documents incident to the offering and sale of that Selling Holder's Registrable Common by means of the Sellers' Registration Statement as that Selling Holder from time to time reasonably may request; (iv) prior to the time the Seller's Registration Statement or any post-effective amendment thereto becomes effective under the Securities Act, provide an opportunity to review and comment with respect to that document to one counsel selected by Selling Holders holding a majority of the shares of Registrable Common covered by that document and reasonably satisfactory to IVT; (v) provide to each Selling Holder, any managing underwriter participating in the distribution of the shares of Registrable Common covered by the Sellers' Registration Statement and any accountant, lawyer or other professional retained by that Selling Holder or managing underwriter (each an "Inspector") reasonable access to appropriate officers and employees of IVT to ask questions and obtain information reasonably requested by that Inspector in connection with that Sellers' Registration Statement; provided, however, that in connection with any such access or request, each Selling Holder will and will cause each of its representative Inspectors to, and IVT may require each other Inspector to, (A) cooperate to the extent reasonably practicable to minimize any disruption in the operation by IVT of its business, (B) keep confidential all records, documents and information IVT advises are confidential or of a proprietary nature (collectively, the "Records") and (C) not use the information it obtains from the Records as a basis for any market transactions in the securities of IVT unless and until that information is in the public domain or otherwise becomes publicly available; (vi) use its good-faith efforts to register and qualify the Registrable Common covered by the Sellers' Registration Statement under the applicable securities or "blue sky" laws (collectively, "Blue Sky Laws") of such jurisdictions as any Selling Holder reasonably may request; provided that it will not be required to (A) qualify generally to do business in any jurisdiction where it otherwise would not be required to qualify but for this paragraph (vi), (B) subject itself to taxation in any such jurisdiction or (C) consent to general service of process in any such jurisdiction; -6- (vii) notify each Selling Holder promptly (A) when it is informed that the Sellers' Registration Statement or any post-effective amendment thereto becomes effective under the Securities Act, (B) of any request by the SEC for an amendment to the Sellers' Registration Statement or a supplement to any related prospectus, (C) of the issuance by the SEC of any stop order suspending the effectiveness of the Sellers' Registration Statement or any order preventing or suspending the use of any related prospectus or the initiation or threat by the SEC of any proceeding for any of those purposes, (D) of the suspension of the qualification of any shares of Registrable Common covered by the Sellers' Registration Statement for sale in any jurisdiction or the initiation or threat of any proceeding for that purpose and (E) of any determination by it that any event has occurred or fact exists which makes untrue any statement of a material fact included in the Sellers' Registration Statement or any related then current prospectus or which requires the making of a change in the Sellers' Registration Statement or that prospectus in order that the same will not contain any untrue statement of a material fact or omit to state a material fact required to be contained therein or necessary to make the statements therein not misleading; (viii)if any order is issued which (A) suspends the effectiveness of the Sellers' Registration Statement, (B) suspends or prevents the use of any related then-current prospectus or (C) suspends the qualification of any shares of Registrable Common covered by the Sellers' Registration Statement for sale in any jurisdiction, use its reasonable best efforts to obtain the withdrawal of that order; (ix) if the Eligible Offering to which the Sellers' Registration Statement relates is being underwritten by underwriters, (A) enter into agreements customary at the time (including an underwriting or purchase agreement in then-customary form) as those underwriters reasonably may request in order to facilitate the disposition of the shares of Registrable Common in that offering, (B) use reasonable diligence to obtain an opinion of legal counsel (who may be its general counsel) covering such matters as are then customarily covered by opinions addressed to those underwriters by an issuer's counsel and (C) use reasonable diligence to obtain a "comfort" letter or letters from its independent public accountants in their customary form and covering such matters of the type then customarily covered by "comfort" letters as those underwriters reasonably may request; and (x) otherwise use its good-faith efforts to comply with all applicable rules and regulations of the SEC and make available to its security holders, as soon as reasonably practicable, an earnings statement that (A) covers a period of at least 12 months beginning within three months after the effective date of the Sellers' Registration Statement and (B) satisfies the provisions of Section 11(a) of the Securities Act. (b) In connection with each Eligible Offering, IVT, in its sole discretion, will determine whether to proceed with or terminate that offering and to select any underwriter or underwriters to administer that offering. -7- 5. UNDERWRITING ARRANGEMENTS. No Holder will be permitted to participate in any registration hereunder of securities being underwritten and offered for resale by underwriters unless the Holder (i) agrees to sell the Holder's Registrable Common on the basis provided in any underwriting arrangements approved by the Persons entitled hereunder to approve those arrangements, (ii) enters into a written agreement with the managing underwriter or the representative of the underwriters in such form and containing such provisions as are then customary in the securities business for such an arrangement between those underwriters and issuers of IVT's size and investment stature and (iii) completes and executes all questionnaires, powers of attorney, indemnities and other documents, and obtains such spousal or other consents, as are reasonably required under the terms of those arrangements and this Agreement. If a Selling Holder disapproves of the proposed terms of any such underwriting, it may elect to withdraw therefrom by written notice to the Company and the managing underwriter, delivered not less than seven days before the Sellers' Registration Statement is first declared effective under the Securities Act. 6. RULE 144 REPORTING. IVT will: (i) make and keep public information available (as those terms are understood and defined in Rule 144) at all times from and after 90 days following the IPO Closing Date; (ii) use its good-faith efforts to file with the SEC in a timely manner all reports and other documents Section 13 or 15(d) of the Exchange Act, as applicable, requires it to file with the SEC; and (iii) so long as a Holder owns shares of Registrable Common, deliver to the Holder, on the Holder's request, a written statement as to whether it is in compliance with the requirements referred to in clause (ii) above (if it is then subject to those requirements). 7. MARKET STANDOFF. Each Holder agrees, to the extent permitted by applicable law, that, for so long as the Holder holds shares of Registrable Common, the Holder will not, except as permitted by Section 2, sell, transfer or otherwise dispose of in a public transaction (including through put or short-sale arrangements) shares of Common Stock in the period (i) beginning 10 days prior to the effectiveness under the Securities Act of any registration statement covering shares of Common Stock being publicly offered in an Eligible Offering or in an Exempt Offering of the type specified in clause (iii) of the definition of Exempt Offering and (ii) ending 90 days following the date of that effectiveness (each such period being a "Lockup Period"). IVT will provide each Holder written notice of any Lockup Period. 8. REGISTRATION EXPENSES. (a) Except as provided in Section 8(b), IVT will pay or otherwise bear all the expense attributable to the registration of Registrable Common under the Securities Act for sale pursuant to Section 2, including all the following: (i) registration and filing fees payable under the Securities Act or Blue Sky Laws; (ii) fees and expenses incurred in complying with Blue Sky Laws, including the reasonable fees and disbursements of counsel incurred in that connection; (iii) printing expenses; (iv) messenger and delivery expenses; (v) the Company's -8- internal expenses, including the salaries and expenses of its employees; (vi) fees and expenses attributable to the listing of the Registrable Common on each securities exchange (including, for this purpose, the NASDAQ national market) on which the Common Stock is then listed at IVT's initiation; (vii) registrar and transfer agents' fees; (viii) fees and disbursements of IVT's counsel and independent certified public accountants; (ix) securities act liability insurance premiums (if IVT elects to obtain that insurance); and (x) fees and expenses of any special experts or other Persons retained by IVT in connection with its compliance with this Agreement. (b) Each Selling Holder will pay or otherwise bear all underwriting commissions and discounts and transfer taxes attributable to that Selling Holder's sale or other disposition of shares of Registrable Common, and each Holder will pay or otherwise bear (i) the fees and expenses of that Holder's counsel and any other special experts or Persons retained by that Holder in connection with any Seller's Registration Statement or the sale or other disposition of that Holder's Registrable Common and (ii) that Holder's internal expenses, including the salaries and expenses of that Holder's employees. 9. TRANSFERS AND ADDITIONAL GRANTS OF REGISTRATION RIGHTS. (a) A Holder may not transfer the registration rights this Agreement affords the Holder to any other Person except as provided in this Section 9: (i) a Holder who is a natural person may transfer those rights to a member of his immediate family or a trust for the benefit of one or more members of his immediate family; (ii) a Holder that is a corporation or other entity may transfer those rights to an Affiliate of the Holder which also is a corporation or other entity; and (iii) a Holder may transfer those rights to any other Holder; provided, that any such transfer will be permitted only if the transferee executes an addendum to this Agreement, in a form satisfactory to IVT, in which that transferee agrees to comply with and otherwise be bound by all the terms and conditions hereof. (b) IVT may, without the consent of any Holder, extend the registration rights this Agreement provides to additional Persons who become holders of Common Stock after the date hereof by entering into one more addenda to this Agreement with those Persons pursuant to which, for all purposes hereof, those Persons will become Holders and any shares of Common Stock referred to in those addenda will become Registrable Common. Nothing herein will limit or otherwise restrict the ability or right of IVT to grant to any Person any registration or similar rights in the future respecting shares of Common Stock or any other securities IVT may issue, whether pursuant to the provisions of this Section 9 or otherwise. 10. INDEMNIFICATION; CONTRIBUTION. (a) INDEMNIFICATION BY IVT. IVT will, to the extent permitted by applicable law, indemnify each Selling Holder who sells shares of Registrable Common by means of a Sellers' Registration Statement and each of that Selling Holder's Related Parties against, and hold each of those Persons harmless from and in respect of, any and all claims, damages, losses, liabilities and expenses (including reasonable legal expenses) whatsoever (collectively, "Claims") that arise from or are based on any untrue statement or alleged untrue statement of a material fact contained in that Sellers' Registration Statement or any prospectus (including any preliminary prospectus) forming a part thereof, or any amendment thereof or -9- supplement thereto, or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances under which they were made, except insofar as those Claims arise out of or are based on any such untrue statement or omission or allegation thereof based on information furnished in writing to IVT by or on behalf of that Selling Holder expressly for use therein. In connection with any underwritten offering of shares of Registrable Common, IVT will indemnify and hold harmless each participating underwriter and each of that underwriter's Related Parties on either (i) substantially the same basis on which it will indemnify each Selling Holder and that Selling Holder's Related Parties pursuant to this Section 10(a) or (ii) such other basis as is customarily obtained by underwriters from issuers at the time of that offering. Notwithstanding the foregoing, IVT's obligations to indemnify and hold harmless pursuant to this Section 10(a) with respect to any Claim (or action or proceeding in respect thereof) that arises from or is based on any untrue or alleged untrue statement contained in, or any omission or alleged omission from, any preliminary prospectus will not inure to the benefit of any Selling Holder or underwriter or its Related Parties if it is determined that (i) a copy of the prospectus used to confirm the sale of shares of Registrable Common to the Person asserting that claim was not sent or given to that Person at or prior to the written confirmation of that sale, (ii) the untrue statement or alleged untrue statement or the omission or alleged omission was corrected by that prospectus and (iii) it was the responsibility of that Selling Holder or that underwriter (or any dealer acquiring those shares directly or indirectly from that underwriter) to send or give that prospectus to that Person. (b) CONDUCT OF INDEMNIFICATION PROCEEDINGS. Each Person claiming indemnification from IVT pursuant to this Section 10 (an "Indemnified Party") will, promptly after that Indemnified Party becomes aware of any assertion or commencement of any action or proceeding against that Indemnified Party in respect of which indemnity may be sought from IVT (a "Proceeding"), promptly notify IVT in writing of the Proceeding; provided, that an Indemnified Party's failure to so notify IVT will not relieve IVT from any liability it may have to that Indemnified Party otherwise than pursuant to the provisions of this Section 10. If any Proceeding is brought against any Indemnified Party and that Indemnified Party duly notifies IVT thereof: (i) IVT will have the right, at its expense, to assume the defense thereof, including the employment of counsel; and (ii) the Indemnified Party will have the right to employ separate counsel in the Proceeding and participate in the defense thereof, but the Indemnified Party will pay the fees and expenses of that separate counsel unless (A) IVT has agreed in writing to pay those fees and expenses or (B) the named parties to the Proceeding (including any impleaded parties) include both the Indemnified Party and IVT, and counsel advises the Indemnified Party in writing that one or more legal defenses may be available to the Indemnified Party which is or are different from or additional to those available to IVT (in which case, if the Indemnified Party notifies IVT in writing that the Indemnified Party elects to employ separate counsel at the expense of IVT, IVT will not have the right to assume the defense of the Proceeding on behalf of the Indemnified Party; it being understood, however, that IVT will not, in connection with any one Proceeding or separate but substantially similar or related Proceedings in the same jurisdiction and arising out of the same general allegations or circumstances, be liable for the fees and expenses of more than one separate law firm (together with appropriate local counsel) at any time for all Indemnified Parties). IVT will -10- not be liable for any settlement of any Proceeding which any Indemnified Party effects without IVT's written consent. (c) INDEMNIFICATION BY SELLING HOLDERS. Each Selling Holder will, to the extent permitted by applicable law, indemnify IVT and each of its Related Parties against, and hold each of those Persons harmless from and in respect of, Claims to the same extent as the indemnity from IVT to that Selling Holder in Section 10(a), but only with respect to information that is furnished by or on behalf of that Selling Holder expressly for use in a Sellers' Registration Statement or any prospectus (including any preliminary prospectus) forming a part thereof, or any amendment thereof or supplement thereto. If any action or proceeding is brought against IVT or any of its Related Parties in respect of which any of those Persons may seek indemnity from a Selling Holder pursuant to this Section 10(c), that Selling Holder will have the rights and duties given to IVT, and each of those Persons will have the rights and duties given to that Selling Holder and that Selling Holder's Related Parties, by Section 10(b). Each Selling Holder also will, to the extent permitted by applicable law, indemnify and hold harmless the underwriters of the shares of Registrable Common offered by that Selling Holder on substantially the same basis on which IVT will indemnify and hold harmless those Persons pursuant to Section 10(a). (d) CONTRIBUTION. If the indemnification this Section 10 provides for is unavailable to any party intended to be indemnified pursuant to this Section 10 in respect of any Claims referred to herein, the parties who would have indemnified that party in the contemplation of this Section 10 will, in lieu of providing that indemnification, contribute to the amount paid or payable by that party as a result of those Claims, as follows: (i) as between IVT and the Selling Holders, on the one hand, and the underwriters of shares of Registrable Common, on the other hand, (A) in such proportion as is appropriate to reflect the relative benefits received by IVT and the Selling Holders and by those underwriters from the offering of those shares or, if that allocation is not permitted by applicable law, (B) in such proportion as is appropriate to reflect not only those relative benefits, but also the relative faults of IVT and the Selling Holders and of those underwriters in connection with the statements or omissions that resulted in those Claims, as well as any other relevant equitable considerations; and (ii) as between IVT, on the one hand, and each Selling Holder, on the other hand, in such proportion as is appropriate to reflect the relative faults of IVT and of that Selling Holder in connection with those statements or omissions, as well as any other relevant equitable considerations. The relative benefits received by IVT and the Selling Holders, on the one hand, and the underwriters participating in the underwritten offering of shares of Registrable Common, on the other hand, will be deemed to be in the same proportion as the total proceeds from that offering (including shares of Common Stock being offered by IVT), net of underwriting discounts and commissions, but before deducting expenses, bear to the total amount of underwriting discounts and commissions received -11- by those underwriters in that offering, while (i) relative faults of IVT and the Selling Holders and of those underwriters will be determined by reference to, among other facts, whether the statements or omissions that resulted in the Claims in respect of which contribution is being made are or relate to information supplied by IVT and the Selling Holders or by those underwriters and (ii) the relative faults of IVT and of the Selling Holders will be determined by reference to, among other facts, (A) whether those statements or omissions are or relate to information supplied by IVT or by the Selling Holders and (B) those Persons' relative intent, knowledge, access to information and opportunity to correct those statements or omissions or prevent them from being made. IVT and the Selling Holders agree it would not be just or equitable if contribution pursuant to this Section 10(d) were to be determined by pro rata allocation (even if the underwriters, if any, were to be treated as one entity for this purpose) or by any other allocation method that does not take into account the equitable considerations referred to in this Section 10(d). (e) LIMITATIONS ON CONTRIBUTION. No underwriter will be required to contribute to IVT or the Selling Holders, pursuant to Section 10(d) or otherwise, any amount in excess of the amount by which (i) the total price at which the shares of Registrable Common underwritten by it and distributed to the public were offered to the public exceeds (ii) the amount of any damages it otherwise has been required to pay by reason of the statements or omissions that resulted in the Claims in respect of which contribution is being made, and no Selling Holder will be required to contribute to IVT or any underwriter, pursuant to Section 10(d) or otherwise, any amount in excess of the amount by which (i) the total price at which that Selling Holder's shares of Registrable Common were offered to the public exceeds (ii) the amount of any damages that Selling Holder otherwise has been required to pay by reason of those statements or omissions. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) will be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. If indemnification is available under this Section 10, the indemnifying parties will indemnify each indemnified party to the full extent provided in Sections 10(a) and (c) without regard to the relative fault of any Person or any other equitable consideration referred to in Section 10(d). 11. MISCELLANEOUS. (a) AMENDMENTS AND WAIVERS. Except as otherwise provided herein, the provisions of this Agreement may not be amended, modified or supplemented, and waivers or consents to departures from the provisions hereof may not be given, unless IVT has obtained the written consent of Holders of at least 51% of the shares of Registrable Common then outstanding.
