Ladies and Gentlemen:

Aladdin Knowledge Systems Ltd., an Israeli corporation (the “Company”), proposes to issue and sell to the underwriters named in Schedule A annexed hereto (the “Underwriters”), for whom you are acting as representative(s) (the “Representatives”), an aggregate of 2,600,000 ordinary shares (the “Firm Shares”), NIS 0.01 par value, of the Company (the “Ordinary Shares”). In addition, solely for the purpose of covering over-allotments, the persons named in Schedule B hereto (the “Selling Shareholders”) propose to grant to the Underwriters an option to purchase from the Selling Shareholders an additional 390,000 Ordinary Shares (the “Additional Shares”). 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 F-3 (File No. 333-121361) including a prospectus, relating to the Shares, which incorporates by reference documents which the Company has filed or will file in accordance with the provisions of the Securities Exchange Act of 1934, as amended, and the rules and regulations thereunder (collectively, the “Exchange Act”). The Company has furnished to you, for use by the Underwriters and by dealers, copies of one or more preliminary prospectuses and the documents incorporated by reference therein (each such preliminary prospectus, including the documents incorporated therein by reference, being herein called a “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 or incorporated by reference therein, and including any information

-3-

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, including all documents incorporated therein by reference, 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 National Association of Securities Dealers Automated Quotation National Market System (“NASDAQ”) is open for trading.

Each of the Company, the Underwriters and the Selling Shareholders, severally and not jointly, agree as follows:

1.Sale and Purchase. Upon the basis of the representations and warranties and subject to the terms and conditions herein set forth, the Company agrees to issue and sell to the respective Underwriters and each of the Underwriters, severally and not jointly, agrees to purchase from the Company 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 10 hereof, in each case at a purchase price of $_____ per Share. The Company 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 initial public offering to such extent as you may determine. In addition, the Selling Shareholders 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 Shareholders all or a portion of the number of Additional Shares set forth opposite the name of such Selling Shareholder in Schedule B, 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 Company for the Firm Shares. To the extent that the Underwriters exercise the option to purchase fewer than the total number of Additional Shares offered hereunder, the Underwriters shall purchase Additional Shares from each Selling Shareholder in the same proportion that the number of Additional Shares offered by such Selling Shareholder bears to the total number of Additional Shares offered by the Selling Shareholders. This option may be exercised by UBS Securities LLC (“UBS”) on behalf of the several Underwriters at any time and from time to time on or before the thirtieth day following the date of the Prospectus, by written notice to the Company and the Custodian (as defined below). 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 Underwriters 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.

9.Effective Date of Agreement; Termination. This Agreement shall become effective (i) if Rule 430A under the Act is not used, when you shall have received notification of the

-26-

effectiveness of the Registration Statement, or (ii) if Rule 430A under the Act is used, when the parties hereto have executed and delivered this Agreement.

The obligations of the several Underwriters hereunder shall be subject to termination in the absolute discretion of UBS or any group of Underwriters (which may include UBS) 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 operations of the Company and the Subsidiaries taken as a whole, which would, in UBS’ 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) since of execution of this Agreement, 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, the NASDAQ or the TASE; (ii) a suspension or material limitation in trading in the Company’s securities on the NASDAQ or on the TASE; (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 Israel or a declaration by the United States or Israel of a national emergency or war; or (v) any other calamity or crisis or any change in financial, political or economic conditions in the United States, Israel or elsewhere, if the effect of any such event specified in clause (iv) or (v) in UBS’ judgment or in the judgment of such group of Underwriters makes 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 (z) since the time of execution of this Agreement, there shall have occurred any downgrading, or any notice or announcement shall have been given or made of (i) any intended or potential downgrading or (ii) any watch, review or possible change that does not indicate an affirmation or improvement in the rating accorded any securities of or guaranteed by the Company or any Subsidiary by any “nationally recognized statistical rating organization,” as that term is defined in Rule 436(g)(2) under the Act.

If UBS or any group of Underwriters elects to terminate this Agreement as provided in this Section 7, the Company 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 shall be unable to comply with any of the terms of this Agreement, the Company 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 under this Agreement (except to the extent provided in Section 11 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

-27-

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 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. Indemnity and Contribution.

(a)The Company 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

-28-

(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 (A) 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 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, or (B) that the indemnity provided in this Section 11(a) shall not inure to the benefit of any Underwriter from whom the person asserting any such loss, damage, expense, liability or claim purchased the Shares concerned, to the extent that any such damage, expense, liability or claim of such Underwriter occurs where it shall be determined by a court of competent jurisdiction by final and non-appealable judgment that (w) delivery of the Prospectus was required under the Act, (x) the Company had previously furnished copies of the Prospectus to the Representatives in sufficient quantity and in sufficient time to enable the Representatives to satisfy their delivery obligations under the Act, (y) the untrue statement or omission of a material fact contained in the preliminary prospectus was corrected in the Prospectus and (z) such loss, claim, damage or liability results solely from the fact that there was not sent or given to such person at or prior to the written confirmation of the sale of such Shares to such person, a copy of the Prospectus), or (ii) any violation or alleged violation by the Company of Section 5 of the Act.

(b)Each Selling Shareholder agrees to indemnify, defend and hold harmless each Underwriter, its partners, directors and officers, and any person who controls the 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 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 which the Selling Shareholder knew or after the exercise of reasonable care should have known, to be untrue or inaccurate, or arises out of or is based upon any omission or alleged omission to state a material fact which the Selling Shareholder knew or after the exercise of reasonable care

-29-

should have known, was required to be stated in either such Registration Statement or such Prospectus or knew or after the exercise of reasonable care should have known was necessary to make the statements made therein not misleading (except (A) 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 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, or (B) that the indemnity provided in this Section 11(a) shall not inure to the benefit of any Underwriter from whom the person asserting any such loss, damage, expense, liability or claim purchased the Shares concerned, to the extent that any such damage, expense, liability or claim of such Underwriter occurs where it shall be determined by a court of competent jurisdiction by final and non-appealable judgment that (w) delivery of the Prospectus was required under the Act, (x) the Company had previously furnished copies of the Prospectus to the Representatives in sufficient quantity and in sufficient time to enable the Representatives to satisfy their delivery obligations under the Act, (y) the untrue statement or omission of a material fact contained in the preliminary prospectus was corrected in the Prospectus and (z) such loss, claim, damage or liability results solely from the fact that there was not sent or given to such person at or prior to the written confirmation of the sale of such Shares to such person, a copy of the Prospectus); provided, however, that, in any event, no Selling Shareholder 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 (net of underwriting discounts but before deduction of expenses) to be received by such Selling Shareholder from the sale of Shares hereunder.

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 the Selling Shareholders pursuant to the foregoing Section 11(a) or (b), such Underwriter or such person shall promptly notify the Company or such Selling Shareholder in writing of the institution of such Proceeding and the Company and such Selling Shareholder (each an “Indemnifying Party”, as the case may be) 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 Indemnifying Party shall not relieve the Indemnifying Party from any liability which the Indemnifying Party 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 Indemnifying Party in connection with the defense of such Proceeding or the Indemnifying Party 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 Indemnifying Party (in which case the Indemnifying Party shall not have the right to direct the defense of such Proceeding on behalf

-30-

of the indemnified party or parties), in any of which events such fees and expenses shall be borne by the Indemnifying Party and paid as incurred (it being understood, however, that the Indemnifying Party 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 Indemnifying Party shall not be liable for any settlement of any Proceeding effected without its written consent but if settled with the written consent of the Indemnifying Party, the Indemnifying Party 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 Shareholder and its directors and officers and any person who controls the Company or any Selling Shareholder 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 Shareholder 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 Shareholder, or any such person in respect of which indemnity may be sought against any Underwriter pursuant to the foregoing paragraph, the Company, the Selling Shareholder 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

-31-

notify such Underwriter shall not relieve such Underwriter from any liability which such Underwriter may have to the Company, any Selling Shareholder or any such person or otherwise. The Selling Company, the Selling Shareholder 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, the Selling Shareholders 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 Shareholder 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) and (b) 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 and the Selling Shareholders 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 or the Selling Shareholders on the one hand and of the

-32-

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 Shareholders 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 Shareholders 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 Shareholders 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, the Selling Shareholders 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, the Selling Shareholders 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 I above. Notwithstanding the provisions of this Section 11, (i) 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 and (ii) no Selling Shareholder shall be required to contribute any amount in excess of the proceeds (net of underwriting discounts but before deducting expenses) to be received by such Selling Shareholder in respect of the Shares sold by such Selling Shareholder hereunder. 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. The Selling Shareholders' obligations to contribute pursuant to this Section 11 are several in proportion to their respective proceeds (net of underwriting discounts but before deducting expenses) to be received by such Selling Shareholder in respect of the Shares sold by such Selling Shareholder hereunder and not joint.

(f)The indemnity and contribution agreements contained in this Section 11 and the covenants, warranties and representations of the Company and the Selling Shareholders 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 Shareholder 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

-33-

Agreement or the issuance and delivery of the Shares. The Company, each Selling Shareholder 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 Shareholders, against any of the Company’s or the Selling Shareholder’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.

12.Information Furnished by the Underwriters. The statements set forth in the last paragraph on the cover page of the Prospectus and the statements set forth in the fourth paragraph under the section "Underwriting", the section "Underwriting -- Price stabilization, short positions", the section "Underwriting -- Over-allotment option" and the first paragraph under the heading "Underwriting -- Commissions and discounts" and the names of the respective underwriters contained on the cover page and the information in the table following the first paragraph under the heading "Underwriting" in the Prospectus constitute the only information furnished by or on behalf of the Underwriters as such information is referred to in Sections 3 and 11 hereof.

13.Notices. Except as otherwise herein provided, all statements, requests, notices and agreements shall be in writing or by telegram and, if to the Underwriters, shall be sufficient in all respects if delivered or sent to UBS Securities LLC, 299 Park Avenue, New York, New York, 10171-0026, Attention: Syndicate Department and, if to the Company, shall be sufficient in all respects if delivered or sent to the Company at the offices of the Company at 15 Beit Oved Street, Tel Aviv 61110, Israel, Attention: Jacob (Yanki) Margalit.

14.Governing Law; Construction. This Agreement and any claim, counterclaim or dispute of any kind or nature whatsoever arising out of or in any way relating to this Agreement (“Claim”), directly or indirectly, shall be governed by, and construed in accordance with, the laws of the State of New York. The Section headings in this Agreement have been inserted as a matter of convenience of reference and are not a part of this Agreement.

15.Submission to Jurisdiction. Except as set forth below, no Claim may be commenced, prosecuted or continued in any court other than the courts of the State of New York located in the City and County of New York or in the United States District Court for the Southern District of New York, which courts shall have jurisdiction over the adjudication of such matters, and the Company and the Selling Shareholders consent to the jurisdiction of such courts and personal service with respect thereto. The Company and the Selling Shareholders 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 UBS or any indemnified party. Each of UBS, the Company and the Selling Shareholders 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 the Selling Shareholders agree 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 the Selling Shareholders and may be enforced in any other courts to the jurisdiction of which the Company and the Selling Shareholders are or may be subject, by suit upon such judgment. The Company and the Selling Shareholders hereby appoint, without power of revocation, Aladdin Knowledge Systems, Inc. (which hereby accepts such appointment), as its agent to accept and

-34-

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.

16.Parties at Interest. The Agreement herein set forth has been and is made solely for the benefit of the Underwriters, the Company and the Selling Shareholders and to the extent provided in Section 9 hereof the controlling persons, partners, directors and officers referred to in such section, and their respective successors, assigns, heirs, personal representatives and executors and administrators. No other person, partnership, association or corporation (including a purchaser, as such purchaser, from any of the Underwriters) shall acquire or have any right under or by virtue of this Agreement.

17.Counterparts. This Agreement may be signed by the parties in one or more counterparts which together shall constitute one and the same agreement among the parties.

18.Successors and Assigns. This Agreement shall be binding upon the Underwriters, the Company and the Selling Shareholders and their successors and assigns and any successor or assign of any substantial portion of the Company’s and the Selling Shareholders and any of the Underwriters’ respective businesses and/or assets.

19.Miscellaneous. UBS, an indirect, wholly owned subsidiary of UBS AG, is not a bank and is separate from any affiliated bank, including any U.S. branch or agency of UBS AG. Because UBS is a separately incorporated entity, it is solely responsible for its own contractual obligations and commitments, including obligations with respect to sales and purchases of securities. Securities sold, offered or recommended by UBS are not deposits, are not insured by the Federal Deposit Insurance Corporation, are not guaranteed by a branch or agency, and are not otherwise an obligation or responsibility of a branch or agency.

Ladies and Gentlemen:

This Lock-Up Letter Agreement is being delivered to you in connection with the proposed Underwriting Agreement (the “Underwriting Agreement”) to be entered into by Aladdin Knowledge Systems Ltd. (the “Company”) and you, as Representative of the several Underwriters named therein, with respect to the public offering (the “Offering”) of Ordinary Shares, par value NIS 0.01 per share, of the Company (the “Ordinary Shares”).

In order to induce you to enter into the Underwriting Agreement, the undersigned agrees that for a period of 90 days after the date of the final prospectus relating to the Offering the undersigned will not, without the prior written consent of UBS Securities LLC (“UBS”), (i) sell, offer to sell, contract or agree to sell, hypothecate, pledge, grant any option to purchase or otherwise dispose of or agree to dispose of, directly or indirectly, or file (or participate in the filing of) a registration statement with the Securities and Exchange Commission (the “Commission”) in respect of, or establish or increase a put equivalent position or liquidate or decrease a call equivalent position within the meaning of Section 16 of the Securities Exchange Act of 1934, as amended, and the rules and regulations of the Commission promulgated thereunder with respect to, any Ordinary Shares of the Company or any securities convertible into or exercisable or exchangeable for Ordinary Shares, or warrants or other rights to purchase Ordinary Shares, (ii) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of Ordinary Shares or any securities convertible into or exercisable or exchangeable for Ordinary Shares, or warrants or other rights to purchase Ordinary Shares, whether any such transaction is to be settled

-2-

by delivery of Ordinary Shares or such other securities, in cash or otherwise, or (iii) publicly announce an intention to effect any transaction specified in clause (i) or (ii). The foregoing sentence shall not apply to (a) the registration of or sale to the Underwriters of any Ordinary Shares pursuant to the Offering and the Underwriting Agreement, (b) bona fide gifts, provided the recipient thereof agrees in writing with the Underwriters to be bound by the terms of this Lock-Up Letter Agreement, (c) dispositions to any trust for the direct or indirect benefit of the undersigned and/or the immediate family of the undersigned, provided that such trust agrees in writing with the Underwriters to be bound by the terms of this Lock-Up Letter Agreement or (d) the exercise of stock options granted pursuant to the Company’s stock option/incentive plans or otherwise outstanding on the date hereof, provided that it shall apply to any Ordinary Shares issued upon such exercise.

In addition, the undersigned hereby waives any rights the undersigned may have to require registration of Ordinary Shares in connection with the filing of a registration statement relating to the Offering. The undersigned further agrees that, for a period of 90 days after the date of the final prospectus relating to the Offering, the undersigned will not, without the prior written consent of UBS, make any demand for, or exercise any right with respect to, the registration of Ordinary Shares of the Company or any securities convertible into or exercisable or exchangeable for Ordinary Shares, or warrants or other rights to purchase Ordinary Shares.

Notwithstanding the foregoing, if (1) during the period that begins on the date that is 15 calendar days plus 3 business days before the last day of the 90-day restricted period and ends on the last day of the 90-day restricted period, the Company issues a earnings release or material news or a material event relating to the Company occurs, or (2) prior to the expiration of the 90-day restricted period, the Company announces that it will release earnings results during the 16-day period beginning on the last day of the 90-day period, in either case, the restrictions imposed by this Lock-Up Letter Agreement shall continue to apply until the expiration of the date that is 15 calendar days plus 3 business days after the date on which the issuance of the earnings release or the material news or material event occurs; provided, however, this paragraph will not apply if, within 3 days of the termination of the 90-day restricted period, the Company delivers to UBS a certificate, signed by the Chief Financial Officer or Chief Executive Officer of the Company, certifying on behalf of the Company that the Company’s Ordinary Shares are “actively traded securities,” as defined in Regulation M, 17 CFR 242.101(c)(1). Such notice shall be delivered in accordance with the provisions of the Underwriting Agreement.

If (i) the Company notifies you in writing that it does not intend to proceed with the Offering, (ii) the registration statement filed with the Securities and Exchange Commission with respect to the Offering is withdrawn, or (iii) for any reason the Underwriting Agreement shall be terminated prior to the time of purchase (as defined in the Underwriting Agreement), this Lock-Up Letter Agreement shall be terminated and the undersigned shall be released from its obligations hereunder.

Yours very truly,
