Ladies and Gentlemen:

Comtech Group, Inc., a Maryland corporation (the “Company”), proposes to issue and sell and the persons named in Schedule B annexed hereto (the “Selling Stockholders”) propose to sell the underwriters named in Schedule A annexed hereto (the “Underwriters”), for whom you are acting as representatives (the “Representatives”), an aggregate of shares (the “Firm Shares”) of Common Stock, $0.01 par value (the “Common Stock”), of the Company, of which shares are to be issued and sold by the Company and an aggregate of shares are to be sold by the Selling Stockholders in the respective amounts set forth under the caption “Firm Shares” in Schedule B annexed hereto. In addition, solely for the purpose of covering over-allotments, the Selling Stockholders propose to grant to the Underwriters the option to purchase from the Selling Stockholders up to an additional shares of Common Stock (the “Additional Shares”) in the respective amounts set forth under the caption “Additional Shares” in Schedule B hereto. The Firm Shares and the Additional Shares are hereinafter collectively sometimes referred to as the “Shares.” The Shares are described in the Prospectus which is referred to below.

The Company has filed, in accordance with the provisions of the Securities Act of 1933, as amended, and the rules and regulations thereunder (collectively, the “Act”), with the Securities and Exchange Commission (the “Commission”) a registration statement on Form S-1 (File No. 333-124201) including a prospectus, relating to the Shares. The Company has furnished to you, for use by the Underwriters and by dealers, copies of the preliminary prospectuses dated June 28, 2005 (the “Preliminary Prospectus”) relating to the Shares. Except where the context otherwise requires, the registration statement, as amended when it became or becomes effective, including all documents filed as a part thereof, and including any information contained in a prospectus subsequently filed with the Commission pursuant to Rule 424(b) under the Act and deemed to be part of the registration statement at the time of effectiveness pursuant to Rule 430(A) under the Act and also including any registration statement filed pursuant to Rule 462(b) under the Act, is herein called the “Registration Statement,” and the prospectus, in the form filed by the Company with the Commission pursuant to Rule 424(b) under the Act on or before the second business day after the date hereof (or such earlier time as may be required under the Act) or, if no such filing is required, the form of final prospectus included in the Registration Statement at the time it became effective, is herein called the “Prospectus.” As used herein, “business day” shall mean a day on which the New York Stock Exchange is open for trading.

The Company, the Selling Stockholders and the Underwriters agree as follows:

Sale and Purchase. Upon the basis of the representations and warranties and subject to the terms and conditions herein set forth, the Company and each of the Selling Stockholders, severally and not jointly, agrees to issue and sell to the respective Underwriters and each of the Underwriters,

severally and not jointly, agrees to purchase from the Company and each Selling Stockholder the respective number of Firm Shares (subject to such adjustment as you may determine to avoid fractional shares) which bears the same proportion to the number of Firm Shares to be sold by the Company or by such Selling Stockholders, as the case may be, as the number of Firm Shares set forth opposite the name of such Underwriter in Schedule A attached hereto, subject to adjustment in accordance with Section 8 hereof, in each case at a purchase price of $ per Share. The Company and each Selling Stockholder is advised by you that the Underwriters intend (i) to make a public offering of their respective portions of the Firm Shares as soon after the effective date of the Registration Statement as in your judgment is advisable and (ii) initially to offer the Firm Shares upon the terms set forth in the Prospectus. You may from time to time increase or decrease the public offering price after the public offering to such extent as you may determine.

In addition, the Selling Stockholders hereby grant to the several Underwriters the option to purchase, and upon the basis of the representations and warranties and subject to the terms and conditions herein set forth, the Underwriters shall have the right to purchase, severally and not jointly, from the Selling Stockholders, ratably in accordance with the number of Firm Shares to be purchased by each of them, all or a portion of the Additional Shares as may be necessary to cover over-allotments made in connection with the offering of the Firm Shares, at the same purchase price per share to be paid by the Underwriters to the Selling Stockholders for the Firm Shares. This option may be exercised by the Representatives jointly on behalf of the several Underwriters at any time and from time to time on or before the thirtieth day following the date hereof, by written notice to the Selling Stockholders. Such notice shall set forth the aggregate number of Additional Shares as to which the option is being exercised, and the date and time when the Additional Shares are to be delivered (such date and time being herein referred to as the “additional time of purchase”); provided, however, that the additional time of purchase shall not be earlier than the time of purchase (as defined below) nor earlier than the second business day after the date on which the option shall have been exercised nor later than the tenth business day after the date on which the option shall have been exercised. The number of Additional Shares to be sold to each Underwriter shall be the number which bears the same proportion to the aggregate number of Additional Shares being purchased as the number of Firm Shares set forth opposite the name of such Underwriter on Schedule A hereto bears to the total number of Firm Shares (subject, in each case, to such adjustment as you may determine to eliminate fractional shares), subject to adjustment in accordance with Section 10 hereof.

Pursuant to powers of attorney, which shall be satisfactory to counsel for the Underwriters, granted by each Selling Stockholder, Jeffrey Kang and Hope Ni will act as representatives of the Selling Stockholders.

The obligations of the several Underwriters hereunder shall be subject to termination in the absolute discretion of the Representatives or any group of Underwriters (which may include the Representatives) which has agreed to purchase in the aggregate at least 50% of the Firm Shares, if (x) since the time of execution of this Agreement or the earlier respective dates as of which information is given in the Registration Statement and the Prospectus, there has been any material adverse change or any development involving a prospective material adverse change in the business, properties, management, financial condition or results of operation of the Company and the Subsidiaries taken as a whole, which would, in the Representatives’ judgment or in the judgment of such group of Underwriters, make it impracticable or inadvisable to proceed with the public offering or the delivery of the Shares on the terms and in the manner contemplated in the Registration Statement and the Prospectus, or (y) there shall have occurred: (i) a suspension or material limitation in trading in securities generally on the New York Stock Exchange, the American Stock Exchange or the NASDAQ; (ii) a suspension or material limitation in trading in the Company’s securities on NASDAQ; (iii) a general moratorium on commercial banking activities declared by either federal or New York State authorities or a material disruption in commercial banking or securities settlement or clearance services in the United States; (iv) an outbreak or escalation of hostilities or acts of terrorism involving the United States or a declaration by the United States of a national emergency or war; or (v) any other calamity or crisis

If the Representatives or any group of Underwriters elects to terminate this Agreement as provided in this Section 9, the Company, the Representatives of the Selling Stockholders and each other Underwriter shall be notified promptly in writing.

If the sale to the Underwriters of the Shares, as contemplated by this Agreement, is not carried out by the Underwriters for any reason permitted under this Agreement or if such sale is not carried out because the Company or the Selling Stockholders, as the case may be, shall be unable to comply with any of the terms of this Agreement, the Company or the Selling Stockholders, as the case may be, shall not be under any obligation or liability under this Agreement (except to the extent provided in Sections 5(n), 7 and 11 hereof), and the Underwriters shall be under no obligation or liability to the Company and the Selling Stockholders under this Agreement (except to the extent provided in Section 9 hereof) or to one another hereunder.

10.

Increase in Underwriters’ Commitments. Subject to Sections 8 and 9 hereof, if any Underwriter shall default in its obligation to take up and pay for the Firm Shares to be purchased by it hereunder (otherwise than for a failure of a condition set forth in Section 8 hereof or a reason sufficient to justify the termination of this Agreement under the provisions of Section 9 hereof) and if the number of Firm Shares which all Underwriters so defaulting shall have agreed but failed to take up and pay for does not exceed 10% of the total number of Firm Shares, the non-defaulting Underwriters shall take up and pay for (in addition to the aggregate number of Firm Shares they are obligated to purchase pursuant to Section 1 hereof) the number of Firm Shares agreed to be purchased by all such defaulting Underwriters, as hereinafter provided. Such Shares shall be taken up and paid for by such non-defaulting Underwriters in such amount or amounts as you may designate with the consent of each Underwriter so designated or, in the event no such designation is made, such Shares shall be taken up and paid for by all non-defaulting Underwriters pro rata in proportion to the aggregate number of Firm Shares set opposite the names of such non-defaulting Underwriters in Schedule A.

Without relieving any defaulting Underwriter from its obligations hereunder, the Company and each of the Selling Stockholders agrees with the non-defaulting Underwriters that it will not sell any Firm Shares hereunder unless all of the Firm Shares are purchased by the Underwriters (or by substituted Underwriters selected by you with the approval of the Company or selected by the Company with your approval).

If a new Underwriter or Underwriters are substituted by the Underwriters or by the Company for a defaulting Underwriter or Underwriters in accordance with the foregoing provision, the Company or you shall have the right to postpone the time of purchase for a period not exceeding five business days in order that any necessary changes in the Registration Statement and the Prospectus and other documents may be effected.

The term Underwriter as used in this Agreement shall refer to and include any Underwriter substituted under this Section 10 with like effect as if such substituted Underwriter had originally been named in Schedule A.

If the aggregate number of Firm Shares which the defaulting Underwriter or Underwriters agreed to purchase exceeds 10% of the total number of Firm Shares which all Underwriters agreed to purchase hereunder, and if neither the non-defaulting Underwriters nor the Company shall make

arrangements within the five business day period stated above for the purchase of all the Firm Shares which the defaulting Underwriter or Underwriters agreed to purchase hereunder, this Agreement shall terminate without further act or deed and without any liability on the part of the Company to any non-defaulting Underwriter and without any liability on the part of any non-defaulting Underwriter to the Company. Nothing in this paragraph, and no action taken hereunder, shall relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.

11.

(a)

The Company and Comtech Global as a Selling Stockholder, jointly and severally agree to indemnify, defend and hold harmless each Underwriter, its partners, directors and officers, and any person who controls any Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, and the successors and assigns of all of the foregoing persons, from and against any loss, damage, expense, liability or claim (including the reasonable cost of investigation) which, jointly or severally, any such Underwriter or any such person may incur under the Act, the Exchange Act, the common law or otherwise, insofar as such loss, damage, expense, liability or claim arises out of or is based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or in the Registration Statement as amended by any post-effective amendment thereof by the Company) or in a Prospectus (the term Prospectus for the purpose of this Section 11 being deemed to include any Preliminary Prospectus, the Prospectus and the Prospectus as amended or supplemented by the Company), or arises out of or is based upon any omission or alleged omission to state a material fact required to be stated in either such Registration Statement or such Prospectus or necessary to make the statements made therein not misleading, except insofar as any such loss, damage, expense, liability or claim arises out of or is based upon any untrue statement or alleged untrue statement of a material fact contained in and in conformity with information concerning such Underwriter furnished in writing by or on behalf of such Underwriter through you to the Company expressly for use in such Registration Statement or such Prospectus or arises out of or is based upon any omission or alleged omission to state a material fact in connection with such information required to be stated in such Registration Statement or such Prospectus or necessary to make such information not misleading, provided that the Company and Comtech Global shall not be liable to any Underwriter under the indemnity agreement in this subsection (a)(i) with respect to any Preliminary Prospectus or to the extent that any such loss, claim, damage or liability of such Underwriter results from the fact that such Underwriter sold Shares to a person as to whom it shall be established that there was not sent or given, at or prior to the written confirmation of such sale, a copy of the Prospectus or the Prospectus as then amended or supplemented in any case where such delivery is required by the Act, if, in each case, the Company has previously furnished copies thereof in sufficient quantity to such Underwriter and the loss, claim, damage or liability of such Underwriter results from an untrue statement or omission of a material fact contained in the Preliminary Prospectus which was identified in writing at such time to such Underwriter and corrected in the Prospectus or in the Prospectus as then amended or supplemented; and (ii) any untrue statement or alleged untrue statement made by the Company in Section 3 hereof or the failure by the Company to perform when and as required any agreement or covenant contained herein, or (iii) breach of Section 3j, and breach of Section 5w or Section 6f hereof where applicable by the Company or Comtech Global;] provided, however, that such Underwriter shall first seek indemnity against the Company and to the extent, and only to the extent, that the Company shall be unable to compensate such Underwriter in full for such losses, damages, expenses, liability or claim,

shall such Underwriter seek indemnity against Comtech Global; provided further, that Comtech Global shall not be responsible either pursuant to this indemnity or as a result of any breach of this Agreement, for losses, damages, expenses, liability or claims for an amount in excess of the proceeds to be received by it (before deducting expenses) from the sale of Shares hereunder, on the condition that Comtech Global will not, directly or indirectly, declare and pay any dividends or other distributions to any of its two shareholders, Jeffrey Kang and Nan Ji out of the proceeds to be received by it (before deducting expenses) from the sale of the Shares hereunder for a period of 18 months after the date hereof, without the prior written consent from the Representatives.

If any action, suit or proceeding (each, a “Proceeding”) is brought against an Underwriter or any such person in respect of which indemnity may be sought against the Company or Comtech Global pursuant to the foregoing paragraph, such Underwriter or such person shall promptly notify the Company and Comtech Global in writing of the institution of such Proceeding and the Company shall assume the defense of such Proceeding, including the employment of counsel reasonably satisfactory to such indemnified party and payment of all fees and expenses; provided, however, that the omission to so notify the Company or Comtech Global shall not relieve the Company or Comtech Global from any liability which the Company or Comtech Global may have to any Underwriter or any such person or otherwise. Such Underwriter or such person shall have the right to employ its or their own counsel in any such case, but the fees and expenses of such counsel shall be at the expense of such Underwriter or of such person unless the employment of such counsel shall have been authorized in writing by the Company or Comtech Global in connection with the defense of such Proceeding or the Company or Comtech Global shall not have, within a reasonable period of time in light of the circumstances, employed counsel to have charge of the defense of such Proceeding or such indemnified party or parties shall have reasonably concluded that there may be defenses available to it or them which are different from, additional to or in conflict with those available to the Company or Comtech Global (in which case the Company or Comtech Global shall not have the right to direct the defense of such Proceeding on behalf of the indemnified party or parties), in any of which events such fees and expenses shall be borne by the Company or Comtech Global and paid as incurred (it being understood, however, that the Company or Comtech Global shall not be liable for the expenses of more than one separate counsel (in addition to any local counsel) in any one Proceeding or series of related Proceedings in the same jurisdiction representing the indemnified parties who are parties to such Proceeding). The Company or Comtech Global shall not be liable for any settlement of any Proceeding effected without its written consent but if settled with the written consent of the Company or Comtech Global, the Company or Comtech Global agrees to indemnify and hold harmless any Underwriter and any such person from and against any loss or liability by reason of such settlement. 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 the second sentence of this paragraph, then the indemnifying party agrees that it shall be liable for any settlement of any Proceeding effected without its written consent if (i) such settlement is entered into more than 60 business days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall not have fully 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. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened Proceeding in respect of which any indemnified

party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such Proceeding and does not include an admission of fault, culpability or a failure to act, by or on behalf of such indemnified party.

(b)

Each Selling Stockholder (except for Comtech Global which is covered under section 11(a) above), severally and not jointly, agrees to indemnify, defend and hold harmless each Underwriter, its partners, directors and officers, and any person who controls any Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, and the successors and assigns of all of the foregoing persons, from and against any loss, damage, expense, liability or claim (including the reasonable cost of investigation) which, jointly or severally, any such Underwriter or any such person may incur under the Act, the Exchange Act, the common law or otherwise, insofar as such loss, damage, expense, liability or claim arises out of or is based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or in the Registration Statement as amended by any post effective amendment thereof by the Company) or in a Prospectus (the term Prospectus for the purpose of this Section 11 being deemed to include any Preliminary Prospectus, the Prospectus and the Prospectus as amended or supplemented by the Company), or that arises out of or is based upon any omission or alleged omission to state a material fact required to be stated in either such Registration Statement or such Prospectus or necessary to make the statements made therein not misleading, to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Company or the Underwriters by such Selling Stockholder, directly or through such Selling Stockholder’s Representatives, specifically for use in the preparation thereof, provided that the Company and Comtech Global shall not be liable to any Underwriter under the indemnity agreement in this subsection (a)(i) with respect to any Preliminary Prospectus or to the extent that any such loss, claim, damage or liability of such Underwriter results from the fact that such Underwriter sold Shares to a person as to whom it shall be established that there was not sent or given, at or prior to the written confirmation of such sale, a copy of the Prospectus or the Prospectus as then amended or supplemented in any case where such delivery is required by the Act, if, in each case, the Company has previously furnished copies thereof in sufficient quantity to such Underwriter and the loss, claim, damage or liability of such Underwriter results from an untrue statement or omission of a material fact contained in the Preliminary Prospectus which was identified in writing at such time to such Underwriter and corrected in the Prospectus or in the Prospectus as then amended or supplemented; and or (ii) any untrue statement or alleged untrue statement made by such Selling Stockholder in Section 4 hereof or the failure by such Selling Stockholder to perform when and as required any agreement or covenant contained herein; provided, that no Selling Stockholder shall be responsible, either pursuant to this indemnity or as a result of any breach of this Agreement, for loses, expenses, liability or claims arising out of or based upon such untrue statement or omission or allegation thereof based upon information furnished by any other Selling Stockholder and, in any event, no Selling Stockholder shall be responsible, either pursuant to this indemnity or as a result of any breach of this Agreement, for losses, expenses, liability or claims for an amount in excess of the proceeds to be received by such Selling Stockholder (before deducting expenses) from the sale of Shares hereunder.

If any Proceeding is brought against an Underwriter or any such person in respect of which indemnity may be sought against such Selling Stockholder pursuant to the foregoing paragraph, such Underwriter or such person shall promptly notify such Selling Stockholder in writing of the institution of such Proceeding and such Selling Stockholder shall assume the defense of such Proceeding, including the employment of counsel reasonably satisfactory to such indemnified party and payment of all fees and expenses; provided, however, that the omission to so notify the Company shall not relieve such Selling Stockholder from any liability which such Selling Stockholder may have to any Underwriter or any such person or otherwise. Such Underwriter or such person shall have the right to employ its or their own counsel in any such case, but the fees and expenses of such counsel shall be at the expense of such Underwriter or of such person unless the employment of such counsel shall have been authorized in writing by such Selling Stockholder in connection with the defense of such Proceeding or such Selling Stockholder shall not have, within a reasonable period of time in light of the circumstances, employed counsel to have charge of the defense of such Proceeding or such indemnified party or parties shall have reasonably concluded that there may be defenses available to it or them which are different from, additional to or in conflict with those available to such Selling Stockholder (in which case such Selling Stockholder shall not have the right to direct the defense of such Proceeding on behalf of the indemnified party or parties), in any of which events such fees and expenses shall be borne by such Selling Stockholder and paid as incurred (it being understood, however, that such Selling Stockholder shall not be liable for the expenses of more than one separate counsel (in addition to any local counsel) in any one Proceeding or series of related Proceedings in the same jurisdiction representing the indemnified parties who are parties to such Proceeding). Such Selling Stockholder shall not be liable for any settlement of any Proceeding effected without its written consent but if settled with the written consent of such Selling Stockholder, such Selling Stockholder agrees to indemnify and hold harmless any Underwriter and any such person from and against any loss or liability by reason of such settlement. 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 the second sentence of this paragraph, then the indemnifying party agrees that it shall be liable for any settlement of any Proceeding effected without its written consent if (i) such settlement is entered into more than 60 business days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall not have fully 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. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened Proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such Proceeding and does not include an admission of fault, culpability or a failure to act, by or on behalf of such indemnified party.

(c)

Each Underwriter severally agrees to indemnify, defend and hold harmless the Company, its directors and officers, each Selling Stockholder and any person who controls the Company within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, and the successors and assigns of all of the foregoing persons, from and against any loss, damage, expense, liability or claim (including the reasonable cost of investigation) which, jointly or severally, the Company, any Selling Stockholder or any such person may incur

under the Act, the Exchange Act, the common law or otherwise, insofar as such loss, damage, expense, liability or claim arises out of or is based upon any untrue statement or alleged untrue statement of a material fact contained in and in conformity with information concerning such Underwriter furnished in writing by or on behalf of such Underwriter through you to the Company expressly for use in the Registration Statement (or in the Registration Statement as amended by any post-effective amendment thereof by the Company) or in a Prospectus, or arises out of or is based upon any omission or alleged omission to state a material fact in connection with such information required to be stated in such Registration Statement or such Prospectus or necessary to make such information not misleading.

If any Proceeding is brought against the Company, any Selling Stockholder or any such person in respect of which indemnity may be sought against any Underwriter pursuant to the foregoing paragraph, the Company, any Selling Stockholder or such person shall promptly notify such Underwriter in writing of the institution of such Proceeding and such Underwriter shall assume the defense of such Proceeding, including the employment of counsel reasonably satisfactory to such indemnified party and payment of all fees and expenses; provided, however, that the omission to so notify such Underwriter shall not relieve such Underwriter from any liability which such Underwriter may have to the Company, any Selling Stockholder or any such person or otherwise. The Company, any Selling Stockholder or such person shall have the right to employ its own counsel in any such case, but the fees and expenses of such counsel shall be at the expense of the Company, any Selling Stockholder or such person unless the employment of such counsel shall have been authorized in writing by such Underwriter in connection with the defense of such Proceeding or such Underwriter shall not have, within a reasonable period of time in light of the circumstances, employed counsel to defend such Proceeding or such indemnified party or parties shall have reasonably concluded that there may be defenses available to it or them which are different from or additional to or in conflict with those available to such Underwriter (in which case such Underwriter shall not have the right to direct the defense of such Proceeding on behalf of the indemnified party or parties, but such Underwriter may employ counsel and participate in the defense thereof but the fees and expenses of such counsel shall be at the expense of such Underwriter), in any of which events such fees and expenses shall be borne by such Underwriter and paid as incurred (it being understood, however, that such Underwriter shall not be liable for the expenses of more than one separate counsel (in addition to any local counsel) in any one Proceeding or series of related Proceedings in the same jurisdiction representing the indemnified parties who are parties to such Proceeding). No Underwriter shall be liable for any settlement of any such Proceeding effected without the written consent of such Underwriter but if settled with the written consent of such Underwriter, such Underwriter agrees to indemnify and hold harmless the Company, any Selling Stockholder and any such person from and against any loss or liability by reason of such settlement. 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 the second sentence of this paragraph, then the indemnifying party agrees that it shall be liable for any settlement of any Proceeding effected without its written consent if (i) such settlement is entered into more than 60 business 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. No indemnifying party shall, without the prior written consent of the

indemnified party, effect any settlement of any pending or threatened Proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such Proceeding.

(d)

If the indemnification provided for in this Section 11 is unavailable to an indemnified party under subsections (a), (b) or (c) of this Section 11 or insufficient to hold an indemnified party harmless in respect of any losses, damages, expenses, liabilities or claims referred to therein, then each applicable indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, damages, expenses, liabilities or claims (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other hand from the offering of the Shares or (ii) if the allocation provided by clause (i) above 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 Company and the Selling Stockholders on the one hand and of the Underwriters on the other in connection with the statements or omissions which resulted in such losses, damages, expenses, liabilities or claims, as well as any other relevant equitable considerations. The relative benefits received by the Company and the Selling Stockholders on the one hand and the Underwriters on the other shall be deemed to be in the same respective proportions as the total proceeds from the offering (net of underwriting discounts and commissions but before deducting expenses) received by the Company and the Selling Stockholders and the total underwriting discounts and commissions received by the Underwriters, bear to the aggregate public offering price of the Shares. The relative fault of the Company and the Selling Stockholders on the one hand and of the Underwriters on the other shall be determined by reference to, among other things, whether the untrue statement or alleged untrue statement of a material fact or omission or alleged omission relates to information supplied by the Company and/or the Selling Stockholders or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The amount paid or payable by a party as a result of the losses, damages, expenses, liabilities and claims referred to in this subsection shall be deemed to include any legal or other fees or expenses reasonably incurred by such party in connection with investigating, preparing to defend or defending any Proceeding.

(e)

The Company, Comtech Global, the Selling Stockholders and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 11 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in subsection (d) above. Notwithstanding the provisions of this Section 11, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Shares underwritten by such Underwriter and distributed to the public were offered to the public exceeds the amount of any damage which such Underwriter has otherwise been required to pay by reason of such untrue statement or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations to contribute pursuant to this Section 11 are several in proportion to their respective underwriting commitments and not joint.

(f)

The indemnity and contribution agreements contained in this Section 11 and the covenants, warranties and representations of the Company, Comtech Global and the Selling Stockholders contained in this Agreement shall remain in full force and effect regardless of any investigation made by or on behalf of any Underwriter, its partners, directors or officers or any person (including each partner, officer or director of such person) who controls any Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, or by or on behalf of the Company, its directors or officers, any Selling Stockholder or any person who controls the Company within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, and shall survive any termination of this Agreement or the issuance and delivery of the Shares. The Company, each of the Selling Stockholders and each Underwriter agree promptly to notify each other of the commencement of any Proceeding against it and, in the case of the Company or the Selling Stockholders, against any of the Company’s or Selling Stockholder’s officers or directors, as the case may be, in connection with the issuance and sale of the Shares, or in connection with the Registration Statement or the Prospectus.

The Company and each of the Selling Stockholders hereby consents to personal jurisdiction, service and venue in any court in which any Claim arising out of or in any way relating to this Agreement is brought by any third party against the Representatives or any indemnified party. Each of the Representatives, the Selling Stockholders and the Company (on its behalf and, to the extent permitted by applicable law, on behalf of its stockholders and affiliates) waives all right to trial by

jury in any action, proceeding or counterclaim (whether based upon contract, tort or otherwise) in any way arising out of or relating to this Agreement. The Company and each of the Selling Stockholders agrees that a final judgment in any such action, proceeding or counterclaim brought in any such court shall be conclusive and binding upon the Company and may be enforced in any other courts to the jurisdiction of which the Company is or may be subject, by suit upon such judgment. Each of the Selling Stockholders hereby appoints without power of revocation, Jeffrey Kang as its agent to accept and acknowledge on its behalf service of any and all process which may be served in any action, proceeding or counterclaim in any way relating to or arising out of this Agreement.

19.

[No Fiduciary Duty]. Notwithstanding any preexisting relationship, advisory or otherwise, between the parties or any oral representations or assurances previously or subsequently made by the underwriters, the Company and the Selling Stockholders acknowledge and agree that:

(b)

the Underwriters are not acting as advisors, expert or otherwise, to either the Company or the Selling Stockholders in connection with this offering, sale of the Shares or any other services the Underwriters may be deemed to be providing hereunder, including, without limitation, with respect to the public offering price of the Shares;
