(b) Subject to Section 2(c) hereof, the Company and the Subsidiary Guarantors shall use their reasonable best efforts:

(i) to keep any Shelf Registration Statement continuously effective, supplemented and amended as required by the provisions of Section 3(j) hereof, in order to permit the Prospectus forming a part thereof to be usable by Holders until the earlier of: (1) two years from the last date of original issuance of any Securities or (2) such shorter period ending on the date that (x) all of the Holders of Registrable Securities are able to sell all Registrable Securities immediately without restriction pursuant to Rule 144(k) under the Securities Act or any successor rule thereto, (y) all Registrable Securities registered under the Shelf Registration Statements have been sold and (z) all Registrable Securities have ceased to be outstanding (such period being referred to herein as the “Effectiveness Period”);

The Company and the Subsidiary Guarantors shall not be required to take any action to name any Holder as a selling securityholder in the initial Shelf Registration Statement at the time of its effectiveness or to enable any Holder to use the Prospectus forming a part thereof for resales of Registrable Securities unless such Holder has returned a properly completed and signed Election and Questionnaire to the Company in a timely manner.

The Company and each Subsidiary Guarantor, jointly and severally, shall indemnify and hold harmless each Holder, such Holder’s officers, directors, partners and employees and each person, if any, who controls such Holder within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any and all losses, claims, damages,

II-C-10

liabilities and expenses whatsoever as incurred (including, but not limited to, reasonable attorneys’ fees and any and all reasonable expenses whatsoever incurred in investigating, preparing or defending against any litigation, commenced or threatened, or any claim made whatsoever, and any and all amounts paid in settlement of any claim or litigation), joint or several, to which they or any of them may become subject under the Securities Act, the Exchange Act or otherwise, insofar as such losses, claims, damages, liabilities or expenses (or actions in respect thereof) arise out of, or are based upon:

(i) any untrue statement or alleged untrue statement of a material fact contained in the Shelf Registration Statement or any amendment thereto or any related preliminary prospectus or the Prospectus or any amendment thereto or supplement thereof; or

(ii) the omission or alleged omission to state in the Shelf Registration Statement or any amendment thereto or any related preliminary prospectus or the Prospectus or any amendment thereto or supplement thereof any material fact required to be stated therein or necessary to make the statements therein (in the case of any related preliminary prospectus or the Prospectus or any amendment thereto or supplement thereof, in light of the circumstances under which they were made) not misleading;

provided, however, that the Company and each Subsidiary Guarantor shall not be liable to any such indemnified party in any such case to the extent, but only to the extent, that any such loss, claim, damage, liability or expense arises out of, or is based upon, any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information furnished to the Company by or on behalf of such indemnified party expressly for use therein; and provided, further, that the foregoing indemnity agreement with respect to any preliminary prospectus shall not inure to the benefit of any Holder who failed to deliver a Prospectus (as then amended or supplemented, provided by the Company to the Holders in the requisite quantity and on a timely basis to permit proper delivery on or prior to resale) to the person asserting any loss, claim, damage, liability or expense caused by the untrue statement or alleged untrue statement of a material fact contained in any preliminary prospectus, or caused by any omission or alleged omission to state therein a material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, if such material misstatement or omission or alleged material misstatement or omission was cured, as determined by a court of competent jurisdiction, in such Prospectus and such Prospectus was required by law to be delivered at or prior to the written confirmation of the resale of such Registrable Securities to such person. The foregoing indemnity agreement is in addition to any liability that the Company and each Subsidiary Guarantor may otherwise have to any indemnified party. The Company and each Subsidiary Guarantor also shall indemnify underwriters, their directors and officers and each person who controls such underwriters within the meaning of the Securities Act or Exchange Act substantially to the same extent as provided above with respect to the indemnification of Holders if requested by such Holders.

(b) Indemnification by the Holders. Each Holder, severally and not jointly, shall indemnify and hold harmless the Company, the Subsidiary Guarantors, the officers, directors and employees of the Company and each Subsidiary Guarantor and each person, if any, who controls the Company or any Subsidiary Guarantor within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any and all losses, claims, damages, liabilities and expenses whatsoever as incurred (including, but not limited to, reasonable attorneys’ fees and any and all reasonable expenses whatsoever incurred in investigating, preparing or defending against any litigation, commenced or threatened, or any claim made whatsoever, and any and all amounts paid in settlement of any claim or litigation), joint or several, to which they or any of them may become subject under the Securities Act, the Exchange Act or otherwise, insofar as such losses, claims, damages, liabilities or expenses (or action in respect thereof) arise out of, or are based upon:

II-C-11

therein (in the case of any related preliminary prospectus or the Prospectus or any amendment thereto or supplement thereof, in light of the circumstances under which they were made) not misleading,

in each case to the extent, but only to the extent, that any such loss, claim, damage, liability or expense arises out of or is based upon any untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information pertaining to such Holder and furnished to the Company by or on behalf of such Holder expressly for use therein. The foregoing indemnity agreement is in addition to any liability that any Holder may otherwise have to any indemnified party.

(c) Notices of Claims, Etc. Promptly after receipt by an indemnified party under subsection (a) or (b) above of notice of any claim or the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify the indemnifying party in writing of the claim or the commencement of that action; provided, however, that the failure to notify the indemnifying party shall not relieve it from any liability that it may have under this Section 5, except to the extent, but only to the extent, that it has been materially prejudiced (including the forfeiture of important rights and defenses). If any such claim or action is brought against any indemnified party, and it notifies the indemnifying party thereof, the indemnifying party will be entitled to participate, at its own expense in the defense of such action, and to the extent it may elect by written notice delivered to such indemnified party promptly after receiving the aforesaid notice from such indemnified party, to assume the defense thereof with counsel reasonably satisfactory to such indemnified party; provided, however, that counsel to the indemnifying party shall not (except with the written consent of the indemnified party) also be counsel to the indemnified party. Notwithstanding the foregoing, the indemnified party or parties shall have the right to employ its or their own counsel (but, in any case, only one counsel for all indemnified parties) in any such case, but the fees and expenses of such counsel shall be at the expense of such indemnified party or parties unless:

(i) the employment of such counsel has been authorized in writing by the indemnifying party;

(ii) such indemnifying party shall not have employed counsel to take charge of the defense of such action within a reasonable time after written notice thereof;

(iii) the indemnifying party does not diligently defend the action after assumption of the defense; or

(iv) such indemnified party shall have reasonably concluded that the representation of such indemnified party by the same counsel representing the indemnifying party would be inappropriate under applicable standards of professional conduct due to actual or potential differing interests between them or where there may be one or more defenses reasonably available to such indemnified party that are different from, additional to or in conflict with those available to the indemnifying party, and in any such event the fees and expenses of such separate counsel shall be paid by the indemnifying party as incurred.

The indemnified parties agree that if there are multiple claims against an indemnifying party that are substantially similar, such parties shall, to the extent practicable, consolidate such claims into one legal proceeding If an indemnifying party has assumed the defense of an action pursuant to this paragraph (c), such indemnifying party shall not be liable for any settlement of any claim or action effected without its written consent, which consent may not be unreasonably withheld. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by paragraph (a) or (b) (and as permitted by paragraph (c)) of this Section 5, then the indemnifying party agrees that it shall be liable for any settlement of the related proceeding effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement and (iii) such indemnified party shall have given the indemnifying party at least 30 days’ prior notice of its intention to settle, including the proposed terms of such settlement. No indemnifying party shall, without the prior written consent of the indemnified parties (which consent shall not be unreasonably withheld or delayed), effect any settlement or compromise of, or consent to the entry of judgment with respect to, any pending or threatened claim, investigation, action or proceeding in respect of which indemnity or

II-C-12

contribution may be or could have been sought by an indemnified party under this Section 5 (whether or not the indemnified party or parties are actual or potential parties thereto) unless (x) such settlement, compromise or judgment (i) includes an unconditional release of such indemnified party from all liability arising out of such claim, action, suit or proceeding and (ii) does not include a statement as to or an admission of fault, culpability or any unlawful failure to act by or on behalf of such indemnified party and (y) the indemnifying party confirms in writing its indemnification obligations hereunder with respect to such settlement, compromise or judgment.

(d) Contribution. If the indemnification provided for in this Section 5 is unavailable or insufficient to hold harmless an indemnified party under subsections (a) or (b) above, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages, liabilities and expenses referred to in subsection (a) or (b) above:

(i) in such proportion as is appropriate to reflect the relative benefits received by the indemnifying party or parties, on the one hand, and the indemnified party, on the other hand, from the registration and sale of the Registrable Securities pursuant to the Shelf Registration Statement; or

(ii) if the allocation provided by the foregoing clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the indemnifying party or parties on the one hand and the indemnified party on the other in connection with the statements or omissions that resulted in such losses, claims, damages, liabilities or expenses as well as any other relevant equitable considerations.

The relative benefits received by the Company and the Subsidiary Guarantors, on the one hand, and a Holder, on the other hand, shall be deemed to be in the same proportion as (i) the total proceeds from the offering of the Securities purchased under the Purchase Agreement (net of discounts but before deducting expenses) received by the Company bear to (ii) the excess of the gross proceeds received by such Holder with respect to its resale of Registrable Securities over the price paid by such Holder in its purchase of such Registrable Securities. The relative fault of the Company and the Subsidiary Guarantors, on the one hand, and of a Holder, on the other hand, shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company and the Subsidiary Guarantors or such Holder and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company, the Subsidiary Guarantors and the Holders agree that it would not be just and equitable if contribution pursuant to this Section 5(d) were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to above. The aggregate amount paid as a result of the losses, claims, damages, liabilities or expenses incurred by an indemnified party and referred to in the first sentence of this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating, preparing or defending against any action or claim which is the subject of this subsection (d). Notwithstanding any other provision of this Section 5(d), (i) in no case shall any Holder be required to contribute any amount in excess of the amount by which the gross proceeds received by such Holder from its sale of Registrable Securities pursuant to the Shelf Registration Statement exceeds the amount of damages that such Holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission and (ii) no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 5(d), each person, if any, who controls a Holder within the meaning of the Securities Act or the Exchange Act shall have the same rights to contribution as such Holder and each person, if any, who controls the Company or any Subsidiary Guarantor within the meaning of the Securities Act or the Exchange Act shall have the same rights to contribution as the Company and the Subsidiary Guarantors. The Holders’ respective obligations to contribute pursuant to this Section 5 are several in proportion to the respective amount of Registrable Securities they have sold pursuant to a Registration Statement and not joint. The remedies provided for in this Section 5 are not exclusive and shall not limit any rights or remedies that may otherwise be available to any indemnified party at law or in equity.

(e) The indemnity and contribution provisions contained in this Section 5 shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, or (ii) any investigation made by or on behalf of any indemnified party.

II-C-13

6. Holder’s Obligations.

Each Holder agrees, by acquisition of the Registrable Securities, that no Holder of Registrable Securities shall be entitled to sell any of such Registrable Securities pursuant to a Shelf Registration Statement or to receive a Prospectus relating thereto, unless such Holder has furnished the Company with a properly completed and signed Election and Questionnaire (including the information required to be included in such Election and Questionnaire) and the information set forth in the next sentence. Each Election Holder agrees promptly to furnish to the Company all information required to be disclosed in order to make the information previously furnished to the Company by such Election Holder correct and not misleading and any other information regarding such Election Holder and the distribution of such Registrable Securities as the Company may from time to time reasonably request. Any sale of any Registrable Securities by any Election Holder shall constitute a representation and warranty by such Election Holder that (x) the information relating to such Election Holder and its plan of distribution is as set forth in the Prospectus delivered by such Election Holder in connection with such disposition, (y) such Prospectus does not as of the time of such sale contain any untrue statement of a material fact relating to or provided by such Election Holder or its plan of distribution and (z) such Prospectus does not as of the time of such sale omit to state any material fact relating to or provided by such Election Holder or its plan of distribution necessary in order to make the statements in such Prospectus, in light of the circumstances under which they were made, not misleading.

7. Additional Interest.

(a) If:

(i) on or prior to the Shelf Filing Deadline, a Shelf Registration Statement has not been filed with the Commission;

(ii) on or prior to the Effectiveness Target Date, the initial Shelf Registration Statement has not been declared effective by the Commission (and include, without limitation, any information with respect to an Election Holder that has properly completed, executed and delivered an Election and Questionnaire prior to or on the 20^th calendar day after such Holder’s receipt thereof that is required so that such Holder is named as a selling securityholder in the initial Shelf Registration Statement and is permitted to deliver the Prospectus forming a part thereof to purchasers of such Holder’s Registrable Securities);

(iii) after the Effective Time of any Shelf Registration Statement, such Shelf Registration Statement ceases to be effective or usable for the offer and sale of Registrable Securities (other than due to a Suspension Period), and the Company and the Subsidiary Guarantors fail to file and, in the case of a post-effective amendment, have declared effective, within five Business Days, a post-effective amendment to such Shelf Registration Statement, a supplement to the Prospectus contained therein or a report with the Commission pursuant to Section 13(a), 13(c) or 14 of the Exchange Act to make such Shelf Registration Statement effective or such Prospectus usable;

(iv) prior to or on the 45^th calendar day or 60^th calendar day, as the case may be, of any Suspension Period, such suspension has not been terminated, or Suspension Periods exceed an aggregate of 120 calendar days in any 360-calendar day period; or

(v) the Company and the Subsidiary Guarantors shall have failed to timely comply with any of its obligations set forth in Section 3(a)(ii) hereof

(each such event referred to in clauses (i) through (v), a “Registration Default”), the Company and the Subsidiary Guarantors shall be required to pay additional interest (“Additional Interest”), from and including the day following such Registration Default to but excluding the earlier of (x) the day on which such Registration Default is cured and (y) the date the Shelf Registration Statement is no longer required to be kept effective (the “Registration Default Period”), at a rate per annum equal to an additional one-quarter of one percent (0.25%) of the principal amount of the Registrable Securities that are Securities to and including the 90th calendar day following such Registration Default, and one-half of one percent (0.5%) thereof from and after the 91st calendar day following such Registration Default. In the event any Registrable Securities that are Securities are converted into shares of Common Stock during a Registration Default Period, in lieu of Additional Interest, the Company and the Subsidiary Guarantors will

II-C-14

deliver to each Holder converting during the Registration Default Period, with respect to the portion of the conversion obligation the Company settles in Common Stock, 103% of the number of shares of Common Stock the Holder would have otherwise received upon conversion (“Additional Shares”).

(b) Any amounts to be paid as Additional Interest pursuant to Section 7(a) hereof shall be paid in cash semi-annually in arrears, with the first semi-annual payment due on the first Interest Payment Date following the date on which such Additional Interest began to accrue, to the Holders in whose name the Securities are registered at the close of business on January 15 or July 15, whether or not a Business Day, immediately preceding the relevant Interest Payment Date. Such Additional Interest shall be calculated and paid in the same manner as interest is paid under the Indenture in respect of the Notes

(c) Except as provided in Section 10(a) hereof, the Additional Interest or Additional Shares, as the case may be, as set forth in this Section 7 shall be the exclusive remedy available to the Holders of Registrable Securities for any Registration Default. In no event shall the Company be required to pay Additional Interest in excess of a rate per annum equal to one-quarter of one percent (0.25%) of the principal amount of the Registrable Securities that are Securities to and including the 90th calendar day following such Registration Default, and a rate per annum equal to one-half of one percent (0.5%) thereof from and after the 91st calendar day following such Registration Default, as set forth in Section 7(a), regardless of whether one or multiple Registration Defaults exist. All obligations of the Company set forth in this Section 7 that are outstanding with respect to any Registrable Security at the time such security ceases to be a Registrable Security shall survive until such time as all such obligations with respect to such Registrable Security shall have been satisfied in full. Each Registration Default will constitute a Registration Default whatever the reason for any such event and whether it is voluntary or involuntary or is beyond the control of the Company or pursuant to operation of law or as a result of any action or inaction by the Commission.

8. Rule 144A.

In the event the Company is not subject to Section 13 or 15(d) of the Exchange Act, the Company hereby agrees with each Holder, for so long as any Registrable Securities remain outstanding, to make available to any Holder in connection with any sale thereof and any prospective purchaser of such Registrable Securities from such Holder, the information required by Rule 144A(d)(4) under the Securities Act in order to permit resales of such Registrable Securities pursuant to Rule 144A.

9. Underwritten Offerings.

(a) An Underwriting Majority may, by written notice to the Company, sell its Registrable Securities in an Underwritten Offering pursuant to any Shelf Registration Statement; provided, that no Underwritten Offering shall occur without the prior agreement of the Company.

(b) No Holder may participate in any Underwritten Offering hereunder unless such Holder:

(i) agrees to sell such Holder’s Registrable Securities on the basis provided in any underwriting arrangements approved by the majority of the Holders (calculated in the same manner as an Underwriting Majority ) participating in such Underwritten Offering (the “Participating Majority”); and

(ii) completes and executes all reasonable questionnaires, powers of attorney, indemnities, underwriting agreements, lock-up letters and other documents required under the terms of such underwriting arrangements.

(c) In any such Underwritten Offering, the investment banker or investment bankers and manager or managers that will administer the offering will be selected by the Participating Majority to be included in such Underwriting Offering; provided, that such investment bankers and managers must be reasonably satisfactory to the Company.

II-C-15

10. Miscellaneous.

(a) Specific Performance. The parties hereto acknowledge that there would be no adequate remedy at law if the Company and the Subsidiary Guarantors fail to perform their obligations hereunder and that the Initial Purchaser and the Holders from time to time may be irreparably harmed by any such failure, and accordingly agree that the Initial Purchaser and such Holders, in addition to any other remedy to which they may be entitled at law or in equity and without limiting the remedies available to the Election Holders under Section 7 hereof, shall be entitled to compel specific performance of the obligations of the Company and the Subsidiary Guarantors under this Agreement in accordance with the terms and conditions of this Agreement, in any court of the United States or any State thereof having jurisdiction.

(b) Amendments and Waivers. Except as provided in the next three sentences, this Agreement, including this Section 10(b), may be amended, modified or supplemented and waivers or consents to departures from the provisions hereof may be given, only by a written instrument duly executed by the Company, the Subsidiary Guarantors and a Majority of Holders. In the event of a merger or consolidation or sale, assignment, conveyance, transfer, lease or other disposition of all or substantially all of the properties and assets of the Company and its subsidiaries on a consolidated basis, the Company and the Subsidiary Guarantors shall procure the assumption of its obligations under this Agreement (which it is understood and agreed shall include the registration of any other Applicable Stock on substantially the same terms as provided for the registration of the Common Stock) by the Person (if other than the Company) formed by such consolidation or into which the Company and the Subsidiary Guarantors are merged or the Person who acquires by sale, assignment, conveyance, transfer, lease or other disposition all or substantially all of the properties and assets of the Company and its Subsidiaries on a consolidated basis and this Agreement may be amended, modified or supplemented without the consent of any Holders to provide for such assumption of the Company’s and the Subsidiary Guarantors’ obligations hereunder (including the registration of any other Applicable Stock). Without the consent of any Holders, after the date hereof, on the date that any Subsidiary of the Company becomes a Guarantor under the Indenture, the Company shall cause such Subsidiary to become a party hereto (a “New Subsidiary Guarantor”) by executing a supplemental agreement hereto and delivering the same to the Trustee on behalf of the Holders. Without the consent of each Holder of Securities, no amendment or modification may change the provisions relating to the payment of Additional Interest or the requirement to issue additional shares of Common Stock during a Registration Default Period.

Each Holder of Registrable Securities outstanding at the time of any amendment, modification, supplement, waiver or consent or thereafter shall be bound by any amendment, modification, supplement, waiver or consent effected pursuant to this Section 10(b), whether or not any notice, writing or marking indicating such amendment, modification, supplement, waiver or consent appears on the Registrable Securities or is delivered to such Holder.

(c) Notices. All notices and other communications provided for or permitted hereunder shall be made in writing by hand delivery, by telecopier, by courier guaranteeing overnight delivery or by first-class mail, return receipt requested, and shall be deemed given (i) when made, if made by hand delivery,
(ii) upon confirmation, if made by telecopier, (iii) one Business Day after being deposited with such courier, if made by overnight courier or (iv) on the date indicated on the notice of receipt, if made by first-class mail, to the parties as follows:

or to such other address as such person may have furnished to the other persons identified in this Section 10(c) in writing in accordance herewith.

(d) Parties in Interest. The parties to this Agreement intend that all Holders of Registrable Securities shall be entitled to receive the benefits of this Agreement and that any Election Holder shall be bound by the terms and provisions of this Agreement by reason of such election with respect to the Registrable Securities that are included in a Shelf Registration Statement. All the terms and provisions of this Agreement shall be binding upon, shall inure to the benefit of and shall be enforceable by, the respective successors and assigns of the parties hereto and any Holder from time to time of the Registrable Securities to the aforesaid extent. In the event that any transferee of any Holder of Registrable Securities shall acquire Registrable Securities, in any manner, whether by gift, bequest, purchase, operation of law or otherwise, such transferee shall, without any further writing or action of any kind, be entitled to receive the benefits of and, if an Election Holder, be conclusively deemed to have agreed to be bound by and to perform all of the terms and provisions of this Agreement to the aforesaid extent.

(i) Survival.

(j) Securities Held by the Company or any Subsidiary Guarantor. Whenever the consent or approval of Holders of a specified percentage of principal amount of Securities is required hereunder, Securities held by the Company or its Affiliates (other than subsequent Holders of Securities if such subsequent Holders are deemed to be Affiliates solely by reason of their holdings of such Securities) shall not be counted in determining whether such consent or approval was given by the Holders of such required percentage.

FORM OF NOTICE OF REGISTRATION STATEMENT AND
SELLING SECURITYHOLDER ELECTION AND QUESTIONNAIRE

Notice

Comtech Telecommunications Corp. (the “Company”) has filed, or intends shortly to file, with the Securities and Exchange Commission (the “Commission”) a registration statement on Form S-3 or such other Form as may be available (the “Shelf Registration Statement”) for the registration and resale under Rule 415 of the Securities Act of 1933, as amended (the “Securities Act”), of the Company’s 2.0% Convertible Senior Notes due 2024 (CUSIP
No. 000000XX0) (the “Notes”), and common stock, par value $0.10 per share, issuable upon conversion thereof (the “Shares” and together with the Notes, the “Transfer Restricted Securities”) in accordance with the terms of the Registration Rights Agreement, dated as of January 27, 2004 (the “Registration Rights Agreement”) between the Company and Bear, Xxxxxxx & Co. Inc. A copy of the Registration Rights Agreement is available from the Company. All capitalized terms not otherwise defined herein have the meanings ascribed thereto in the Registration Rights Agreement.

To sell or otherwise dispose of any Transfer Restricted Securities pursuant to the Shelf Registration Statement, a beneficial owner of Transfer Restricted Securities generally will be required to be named as a Selling Securityholder in the related Prospectus, deliver a Prospectus to purchasers of Transfer Restricted Securities, be subject to certain civil liability provisions of the Securities Act and be bound by those provisions of the Registration Rights Agreement applicable to such beneficial owner (including certain indemnification rights and obligations, as described below). To be included in the Shelf Registration Statement, this Election and Questionnaire must be completed, executed and delivered to the Company at the address set forth herein for receipt prior to or on the 20th calendar day from the receipt hereof (the “Election and Questionnaire Deadline”). Beneficial Owners that do not complete this Election and Questionnaire and deliver it to the Company prior to the Election and Questionnaire Deadline as provided below will not be named as Selling Securityholders in the Shelf Registration Statement at the time it is declared effective and, therefore, will not be permitted to sell any Transfer Restricted Securities pursuant to the Shelf Registration Statement until we prepare and file a prospectus supplement or, if required, a post-effective amendment to the Shelf Registration Statement or an additional Shelf Registration Statement.

Certain legal consequences arise from being named as a Selling Securityholder in the Shelf Registration Statement and the related Prospectus. Accordingly, holders and beneficial owners of Transfer Restricted Securities are advised to consult their own securities law counsel regarding the consequences of being named or not being named as a Selling Securityholder in the Shelf Registration Statement and the related Prospectus.

VI.

Plan of Distribution:

Except as set forth below, the undersigned (including its donees or pledgees) intends to distribute the Transfer Restricted Securities listed above in Item III pursuant to the Shelf Registration Statement only as follows (if at all). Such Transfer Restricted Securities may be sold from time to time directly by the undersigned or, alternatively, through underwriters, broker-dealers or agents. If the Transfer Restricted Securities are sold through underwriters or broker-dealers, the Selling Securityholder will be responsible for underwriting discounts or commissions or agent’s commissions. Such Transfer Restricted Securities may be sold in one or more transactions at fixed prices, at prevailing market prices at the time of sale, at varying prices determined at the time of sale, or at negotiated prices. Such sales may be effected in transactions (which may involve crosses or block transactions):

on any national securities exchange or quotation service on which the Transfer Restricted Securities may be listed or quoted at the time of sale;

in the over-the-counter market;

in transactions otherwise than on such exchanges or services or in the over-the-counter market; or

through the writing of options.

In connection with sales of the Transfer Restricted Securities or otherwise, the undersigned may enter into hedging transactions with broker-dealers, which may in turn engage in short sales of the Transfer Restricted Securities and deliver Transfer Restricted Securities to close out such short positions, or loan or pledge Transfer Restricted Securities to broker-dealers that in turn may sell such securities. State any exceptions here:

Note: In no event will such method(s) of distribution take the form of an underwritten offering of the Transfer Restricted Securities without the prior agreement of the Company.

We advise each Selling Securityholder of the following Interpretation A.65 of the July 1997 SEC Manual of Publicly Available Telephone Interpretations regarding short selling:

“An issuer filed a Form S-3 registration statement for a secondary offering of common stock which is not yet effective. One of the selling shareholders wanted to do a short sale of common stock “against the box” and cover the short sale with registered shares after the effective date. The issuer was advised that the short sale could not be made before the registration statement becomes effective, because the shares underlying the short sale are deemed to be sold at the time such sale is made. There would, therefore, be a violation of Section 5 if the shares were effectively sold prior to the effective date.”

By returning this Supplemental Questionnaire, the Selling Securityholder will be deemed to be aware of the foregoing interpretation.

By signing below, the Selling Securityholder acknowledges that it understands its obligation to comply, and agrees it will comply, with the prospectus delivery requirements and other provisions of the Securities Act and the Exchange Act and the respective rules and regulations promulgated thereunder, particularly Regulation M thereunder (or any successor rules or regulations), in connection with any offering of Transfer Restricted Securities pursuant to the Shelf Registration Statement.

If the Selling Securityholder transfers all or any portion of the Transfer Restricted Securities listed in Item III above after the date on which such information is provided to the Company, the Selling Securityholder agrees to notify the transferee(s) at the time of the transfer of its rights and obligations under this Election and Questionnaire and the Registration Rights Agreement.

By signing below, the Selling Securityholder consents to the disclosure of the information contained herein in its answers to Items I through VI above and the inclusion of such information in the Shelf Registration

II-C-23

Statement and, the related Prospectus and any state securities or “Blue Sky” applications. The Selling Securityholder understands that such information will be relied upon by the Company in connection with the preparation or amendment of the Shelf Registration Statement, the related Prospectus and any state securities or “Blue Sky” applications.

In accordance with the Selling Securityholder’s obligation under the Registration Rights Agreement to provide such information as may be required by law for inclusion in the Shelf Registration Statement, the Selling Securityholder agrees to promptly notify the Company of any inaccuracies or changes in the information provided herein that may occur subsequent to the date hereof at any time while the Shelf Registration Statement remains effective. All notices hereunder and pursuant to the Registration Rights Agreement shall be made in writing at the address set forth below.

Once this Election and Questionnaire is executed by the Selling Securityholders and received by the Company, the terms of this Election and Questionnaire and the representations and warranties contained herein shall be binding on, shall inure to the benefit of and shall be enforceable by the respective successors heirs, personal representatives and assigns of the Company and the Selling Securityholder with respect to the Transfer Restricted Securities beneficially owned by such Selling Securityholder and listed in Item III above. This Election and Questionnaire shall be governed by, and construed in accordance with, the laws of the State of New York without regard to the conflicts-of-laws provisions thereof.

IN WITNESS WHEREOF, the undersigned, by authority duly given, has caused this Election and Questionnaire to be executed and delivered either in person or by its authorized agent.
