If a Piggyback Registration is an underwritten registration on behalf of Zoom, and the managing underwriters advise Zoom that in their opinion the aggregate number of securities requested to be included in such registration pursuant to Section 4.16(a) (the "Requested Piggyback Shares") creates a substantial risk that the price per share of Zoom's common stock will need to be reduced, Zoom will include in such registration (i) first, any securities Zoom proposes to sell, and (ii) second, the Requested Piggyback Shares.

41

(c) Control by Zoom. Zoom may withdraw any registration statement and abandon any proposed offering initiated by it without the consent of CNCG, notwithstanding the request of CNCG to participate therein in accordance with Section 4.16(a), if the Board of Directors of Zoom determines in its sole discretion that such action is in the best interest of Zoom.

8.3   Fees and Expenses . All Expenses incurred in connection with this Agreement and the transactions contemplated hereby shall be paid by the Party incurring such expenses, whether or not the Purchase or any other related transaction is consummated. As used in this Agreement, "Expenses7.3(a)Expenses" shall include all out-of-pocket expenses (including all fees and expenses of counsel, accountants, investment bankers, financing sources, experts and consultants

51

to a Party hereto and/or any of its affiliates) incurred by a Party or on its behalf in connection with or related to the authorization, preparation, negotiation, execution or performance of this Agreement or any ancillary agreement related hereto, and all other matters related to the consummation of the Purchase. In addition, in the event action is taken in connection with Section 8.13 below, then the Party taking such action shall be entitled to collect from the other non-affiliated Parties reasonable legal fees incurred in taking such actions.

8.4   Amendment . This Agreement may only be amended pursuant to a written agreement signed by all of the Parties hereto.

8.5   Waiver . At any time prior to the Closing Date, subject to applicable law, Parties may in their sole discretion (i) extend the time for the performance of any obligation or other act of any other non-affiliated Parties hereto, (ii) waive any inaccuracy in the representations and warranties by such other non-affiliated Parties contained herein or in any document delivered pursuant hereto, and (iii) waive compliance by such other non-affiliated Parties with any agreement or condition contained herein. Any such extension or waiver shall be valid only if set forth in an instrument in writing signed by all of the Parties to be bound thereby. Notwithstanding the foregoing, no failure or delay by Zoom, Zoom Sub, CNCG or Portables in exercising any right hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise of any other right hereunder.

8.6   Binding Effect; Assignment . This Agreement and all of the provisions hereof shall be binding upon and inure to the benefit of the Parties hereto and their respective successors and permitted assigns. This Agreement shall not be assigned by operation of law or otherwise without the prior written consent of the other Parties, and any assignment without such consent shall be null and void; provided that no such assignment shall relieve the assigning Party of its obligations hereunder.

8.7   Governing Law; Jurisdiction . This Agreement shall be governed by, construed and enforced in accordance with the laws of the State of New York, without regard to the conflict of laws principles thereof. All Actions arising out of or relating to this Agreement shall be heard and determined exclusively in any state or federal court located in New York, New York. The Parties hereto hereby (A) submit to the exclusive jurisdiction of any state or federal court in New York, New York for the purpose of any Action arising out of or relating to this Agreement brought by any Party hereto and (B) irrevocably waive, and agree not to assert by way of motion, defense or otherwise, in any such Action, any claim that it is not subject personally to the jurisdiction of the above- named courts, that its property is exempt or immune from attachment or execution, that the Action is brought in an inconvenient forum, that the venue of the Action is improper, or that this Agreement or the transactions contemplated hereby may not be enforced in or by any of the above-named courts. Each of the Parties agrees that a final judgment in any action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Each of the Parties irrevocably consents to the service of the summons and complaint and any other process in any other action or proceeding relating to the transactions contemplated by this Agreement, on behalf of itself or its property, by personal delivery of copies of such process to such Party. Nothing in this Section 8.7 shall affect the right of any Party to serve legal process in any other manner permitted by law.

52

8.8   Waiver of Jury Trial . Each of the Parties hereby waives to the fullest extent permitted by applicable law any right it may have to a trial by jury with respect to any Action directly or indirectly arising out of, under or in connection with this Agreement or the transactions contemplated hereby. Each of the Parties (i) certifies that no representative, agent or attorney of any other party has represented, expressly or otherwise, that such other party would not, in the event of any Action, seek to enforce that foregoing waiver and (ii) acknowledges that it and the other Parties hereto have been induced to enter into this Agreement by, among other things, the mutual waivers and certifications in this Section 8.8.

8.9   Counterparts . This Agreement may be executed and delivered (including by facsimile or other electronic transmission) in one or more counterparts, and by the different Parties hereto in separate counterparts, each of which when executed shall be deemed to be an original but all of which taken together shall constitute one and the same agreement.

8.10   Interpretation . The article and section headings contained in this Agreement are solely for the purpose of reference, are not part of the agreement of the Parties and shall not in any way affect the meaning or interpretation of this Agreement. Whenever the words "include," "includes" or "including" are used in this Agreement, they shall be deemed to be followed by the words "without limitation." The words "hereof," "herein," "hereby" and "hereunder" and words of similar import when used in this Agreement shall refer to this Agreement as a whole and not to any particular provision of this Agreement. The Parties have participated jointly in the negotiation and drafting of this Agreement. Consequently, in the event an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the Parties hereto, and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any provision of this Agreement.

8.11   Entire Agreement . This Agreement and the documents or instruments referred to herein, including any exhibits attached hereto and the Zoom Disclosure Letter and the Portables Disclosure Letter referred to herein, which exhibits and disclosure letters are incorporated herein by reference, and the Confidentiality Agreements, embody the entire agreement and understanding of the Parties hereto in respect of the subject matter contained herein. There are no restrictions, promises, representations, warranties, covenants or undertakings, other than those expressly set forth or referred to herein. This Agreement and such other agreements supersede all prior agreements and the understandings among the Parties with respect to such subject matter.

8.12   Severability . In case any provision in this Agreement shall be held invalid, illegal or unenforceable in a jurisdiction, such provision shall be modified or deleted, as to the jurisdiction involved, only to the extent necessary to render the same valid, legal and enforceable, and the validity, legality and enforceability of the remaining provisions hereof shall not in any way be affected or impaired thereby nor shall the validity, legality or enforceability of such provision be affected thereby in any other jurisdiction. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the Parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible in a mutually acceptable manner in order that the Purchase be consummated as originally contemplated to the fullest extent possible.

53

8.13   Specific Performance . The Parties hereto agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed by Portables, CNCG, Zoom or Zoom Sub in accordance with their specific terms or were otherwise breached. Accordingly, the Parties further agree that prior to the termination of this Agreement in accordance with Section 7.1, each Party shall be entitled to seek an injunction or restraining order to prevent breaches of this Agreement and to seek to enforce specifically the terms and provisions hereof, this being in addition to any other right or remedy to which such Party may be entitled under this Agreement, at law or in equity.

8.14   Non-Exclusive Remedy

8.15   Third Parties . Nothing contained in this Agreement or in any instrument or document executed by any Party in connection with the transactions contemplated hereby shall create any rights in, or be deemed to have been executed for the benefit of, any person that is not a Party hereto or thereto or a successor or permitted assign of such a Party.

8.16   Disclosure Letters . The disclosure of any matter in the Zoom Disclosure Letter or the Portables Disclosure Letter, as the case may be, shall be deemed to be a disclosure on all other sections of the Zoom Disclosure Letter or the Portables Disclosure Letter, as the case may be, if such disclosure is in sufficient detail to make it readily apparent to a reasonable Person that such disclosure applies to the other sections thereof to which such disclosure is responsive. Certain of the information set forth in each of the Zoom Disclosure Letter and the Portables Disclosure Letter is included solely for informational purposes and may not be required to be disclosed pursuant to this Agreement. The disclosure of any information shall not be deemed to constitute an acknowledgement that such information is required to be disclosed in connection with the representations and warranties made by the Parties in this Agreement, nor shall such information be deemed to establish a standard of materiality. If there is any inconsistency between the statements in this Agreement and those in the Zoom Disclosure Letter or Portables Disclosure Letter (other than an exception set forth in such Zoom Disclosure Letter or Portables Disclosure Letter), the statements in this Agreement will control.
