GSE SYSTEMS, INC. SENIOR SUBORDINATED SECURED CONVERTIBLE NOTE Issuance Date: May 26, 2005 Principal: U.S. $2,000,000 FOR VALUE RECEIVED, GSE Systems, Inc., a Delaware corporation (the "Company"), hereby promises to pay to the order of Dolphin Direct Equity Partners, LP, or its registered assigns ("Holder"), the amount set forth above as the Principal (as adjusted, pursuant to the terms hereof pursuant to conversion, redemption or otherwise, the "Principal") when due, whether upon the Maturity Date (as defined below), acceleration, redemption or otherwise (in each case in accordance with the terms hereof) and to pay interest ("Interest") on any outstanding Principal at a rate per annum equal to the Interest Rate (as defined below), from the date set out above as the Issuance Date (the "Issuance Date") until the same becomes due and payable, whether upon an Interest Date (as defined below), the Maturity Date, acceleration, conversion, redemption or otherwise (in each case in accordance with the terms hereof). This Convertible Note (including all Convertible Notes issued in exchange, transfer or replacement hereof, this "Note") is duly authorized and issued pursuant to the Securities Purchase Agreement. Certain capitalized terms are defined in Section 26. References herein to the Note or the Warrant mean all such Notes or Warrants to the extent it, any or all of them are reissued, subdivided, transferred, substituted, combined or otherwise restructured in any way, and references to the Holder include all holders of all outstanding such Notes. (1) MATURITY. On the Maturity Date, the Holder shall surrender this Note to the Company and the Company shall pay to the Holder an amount in cash representing all outstanding Principal, accrued and unpaid Interest. The "Maturity Date" shall be March 31, 2009, as may be extended at the option of the Holder in the event that, and for so long as, an Event of Default (as defined in Section 4(a)) shall have occurred and be continuing or any event shall have occurred and be continuing which with the passage of time and the failure to cure would result in an Event of Default. (2) INTEREST; INTEREST RATE. Interest on this Note shall commence accruing at a rate (the "Interest Rate") equal to 8% per annum on the Issuance Date and shall be computed on the basis of a 365-day year and actual days elapsed and shall be payable in arrears on the last day of each calendar quarter and on the Maturity Date during the period beginning on the Issuance Date and ending on, and including, the Maturity Date (each, an "Interest Date") with the first Interest Date being June 30, 2005; provided however that the Interest Rate for each calendar quarter during which the Registration Statement (as defined in the Securities Purchase Agreement) shall have been effective during the entirety thereof shall be as determined above and reduced by the product of (x) 2% multiplied by (y) the whole number quotient, regardless of remainder, of (A) the quotient of (1) the positive amount by which the average Closing Bid for the last ten Trading Days of the then most recently completed calendar quarter exceeds the Co nversion Price (as defined below) as of such date, divided by (2) such Conversion Price, divided by (B) .25. From and after the occurrence of an Event of Default, the Interest Rate shall be increased to twenty-four percent (24%). In the event that such Event of Default is subsequently cured, the increase referred to in the preceding sentence shall cease to be effective as of the date of such cure; provided that the Interest as calculated at such increased rate during the continuance of such Event of Default shall continue to apply to the extent relating to the days after the occurrence of such Event of Default through and including the date of cure of such Event of Default. (3) CONVERSION OF NOTE. This Note shall be convertible into shares of common stock of the Company, par value $.01 per share (the "Common Stock"), on the terms and conditions set forth in this Section 3. (a) Conversion Right. At any time or times on or after the Issuance Date, until any time prior to the close of business on the Business Day prior to the Maturity Date, the Holder shall be entitled to convert any portion of the outstanding and unpaid Conversion Amount (as defined below) in multiples of $1,000 principal amount into fully paid and nonassessable shares of Common Stock in accordance with Section 3(c), at the Conversion Rate (as defined below). The Company shall not issue any fraction of a share of Common Stock upon any conversion. If the issuance would result in the issuance of a fraction of a share of Common Stock, the Company shall round such fraction of a share of Common Stock up to the nearest whole share, or, at the option of the Company, the Company may pay cash to the Holder for the value of any fractional share, based on the Closing Bid Price as of the applicable Conversion Date. The Company shall pay any and all taxes that may be payable with respect to the issuance and delivery of Common Stock upon conversion of any Conversion Amount; provided, however, that the Company shall not be required to pay any tax which may be payable in respect of any transfer involved in the issue or delivery of shares of Common Stock in a name other than that of the Holder and no such issue or delivery to a Person other than the Holder shall be made unless and until the Person requesting such issue and delivery has paid to the Company the amount of any such tax or has established, to the satisfaction of the Company, that such tax has been paid. (b) Conversion Rate. The number of shares of Common Stock issuable upon conversion of any Conversion Amount pursuant to Section 3(a) shall be determined by dividing (x) such Conversion Amount by (y) the Conversion Price (the "Conversion Rate"). (i) "Conversion Amount" means the sum of (A) the portion of the Principal to be converted, redeemed or otherwise with respect to which this determination is being made, and (B) accrued and unpaid Interest with respect to such Principal. (ii) "Conversion Price" means, as of any Conversion Date (as defined below) or other date of determination, and subject to adjustment as provided herein, $1.925, subject to adjustment as provided herein. (c) Mechanics of Conversion. (i) Optional Conversion. To convert any Conversion Amount into shares of Common Stock on any date (a "Conversion Date"), the Holder shall (A) transmit by facsimile (or otherwise deliver) to the Company and the Company shall have received on or prior to 11:59 p.m., New York Time, on such date, a copy of an executed notice of conversion in the form attached hereto as Exhibit I (the "Conversion Notice") to the Company and (B) if required by Section 3(c)(iii), surrender this Note to the Company as soon as practicable on or following such date (or an indemnification undertaking with respect to this Note in the case of its loss, theft or destruction). On or before the second Business Day following the date of receipt of a Conversion Notice (the "Share Delivery Date"), the Company shall execute and deliver, to the address as specified in the Conversion Notice, a certificate, registered in the name of the Holder or its designee, for the number of shares of Common Stock to which the Holder shall be entitled a nd bearing a legend restricting transfer without compliance with applicable securities laws. If this Note is required to be physically surrendered for conversion and the outstanding Principal of this Note is greater than the Principal portion of the Conversion Amount being converted, then the Company shall execute and deliver, at the Company's expense, to the Holder a new Note representing the outstanding Principal not converted. The Person or Persons entitled to receive the shares of Common Stock issuable upon a conversion of this Note shall be treated for all purposes as the record holder or holders of such shares of Common Stock on the Conversion Date. (ii) Company's Failure to Timely Convert. If the Company shall fail to issue a certificate to the Holder for the number of shares of Common Stock to which the Holder is entitled upon conversion of any Conversion Amount on or prior to the date which is five Business Days after the Conversion Date (a "Conversion Failure"), then (A) the Company shall pay damages to the Holder for each date of such Conversion Failure in an amount equal to 1.0% of the product of (I) the sum of the number of shares of Common Stock not issued to the Holder on or prior to the Share Delivery Date and to which the Holder is entitled, and (II) the Closing Sale Price of the Common Stock on the Share Delivery Date and (B) the Holder, upon written notice to the Company, may void its Conversion Notice with respect to, and retain or have returned, as the case may be, any portion of this Note that has not been converted pursuant to such Conversion Notice; provided that the voiding of a Conversion Notice shall not affect the Company's obligations to make any payments which have accrued prior to the date of such notice pursuant to this Section 3(c)(ii) or otherwise. In addition to the foregoing, if within three (3) Trading Days after the Company's receipt of the facsimile copy of a Conversion Notice the Company shall fail to execute and deliver a certificate for the number of shares of Common Stock to which the Holder is entitled upon such Holder's conversion of any Conversion Amount, and if on or after such Trading Day the Holder purchases (in an open market transaction or otherwise) Common Stock to deliver in satisfaction of a sale by the Holder of Common Stock issuable upon such conversion that the Holder anticipated receiving from the Company (a "Buy-In"), then the Company shall, within three Business Days after the Holder's request and in the Holder's discretion, either (i) pay cash to the Holder in an amount equal to the Holder's total purchase price (including brokerage commissions, if any) for the shares of Common Stock so purchas ed (the "Buy-In Price"), at which point the Company's obligation to deliver such certificate (and to issue such Common Stock) shall terminate, or (ii) promptly honor its obligation to issue to the Holder a certificate or certificates representing such Common Stock and pay cash to the Holder in an amount equal to the excess (if any) of the Buy-In Price over the product of (A) such number of shares of Common Stock, times (B) the Closing Bid Price on the Conversion Date. (iii) Book-Entry. Notwithstanding anything to the contrary set forth herein, upon conversion of any portion of this Note in accordance with the terms hereof, the Holder shall not be required to physically surrender this Note to the Company. Following any such conversion of any portion of this Note, the outstanding Principal represented by this Note may be less than the Principal stated on the face of this Note. (iv) Pro Rata Conversion; Disputes. In the event that the Company receives a Conversion Notice from more than one holder of Notes for the same Conversion Date and the Company can convert some, but not all, of such portions of the Notes submitted for conversion, the Company shall convert from each holder of Notes electing to have Notes converted on such date a pro rata amount of such holder's portion of its Notes submitted for conversion based on the principal amount of Notes submitted for conversion on such date by such holder relative to the aggregate principal amount of all Notes submitted for conversion on such date. In the event of a dispute as to the number of shares of Common Stock issuable to the Holder in connection with a conversion of this Note, the Company shall issue to the Holder the number of shares of Common Stock not in dispute and resolve such dispute in accordance with Section 19. (d) Limitation on Conversion. Until the 20-day period referred to in Section 4(c) of the Securities Purchase Agreement has elapsed with the result of permitting the Company to give effect to the Conversion Share Limit Termination (as defined in the Securities Purchase Agreement), or the Company otherwise complies with the Amex Stockholder Approval Requirements (as defined in the Securities Purchase Agreement) with respect to the issuance of this Note, notwithstanding any provision of this Note to the contrary, the Company shall not effect any conversion of this Note, and the Holder of this Note shall not have the right to convert this Note pursuant to Section 3(a), to the extent that giving effect to such conversion would result in the actual issuance of a number of shares of Common Stock, when aggregated with the number of shares of Common Stock actually issued or issuable upon the exercise of the Warrant, in excess of 19.99% of the number of shares of Common Stock outstanding immediately prior to the Subscription Date; provided that the calculation of such percentage at any time shall be made without giving effect to, and assuming the absence of, any adjustment contemplated by Section 7(b) or (c) hereof. (4) EVENT OF DEFAULT. (a) Each of the following events shall constitute an "Event of Default": (i) the suspension from trading or failure of the Common Stock to be listed on an Eligible Market for a period of five (5) consecutive days or for more than an aggregate of ten (10) days in any 365-day period; (ii) the Company's (A) failure to cure a Conversion Failure by delivery of the required number of shares of Common Stock within ten (10) Business Days after the applicable Conversion Date or (B) notice to any holder of the Notes, including by way of public announcement, at any time, of its intention not to comply with a request for conversion of any Notes into shares of Common Stock that are tendered in accordance with the provisions of the Notes; (iii) at any time following the tenth consecutive Business Day that the Holder's Authorized Share Allocation (as defined below) is less than the number of shares of Common Stock that the Holder would be entitled to receive upon a conversion of the full Conversion Amount of this Note (without regard to any limitations on conversion set forth in Section 3(d) or otherwise); (iv) the Company's failure to pay to the Holder any amount of Principal or Interest or other amounts when and as due under this Note or any other Transaction Document; provided (A) in the case of a failure to pay Interest when and as due, that such failure continues for a period of at least five (5) Business Days if no other such failure shall have occurred within twelve months of the date thereof and (B) in the case of a failure to pay any such other amounts (other than Principal and Interest) when and as due, that such failure continues for a period of at least five (5) Business Days after notice is received by the Company specifying such failure if no more than three other such failures cured within such period shall have occurred within twelve months of the date thereof; (v) (A) any of the Company or any of its Subsidiaries shall fail to make any payment (whether of principal or interest and regardless of amount) in respect of any Material Indebtedness, which payment failure individually or when aggregated with all other such payment failures within six months thereof shall be in the amount of at least $25,000, when and as the same shall become due and payable (after giving effect to the expiration of any grace or cure period set forth therein) or (B) any event or condition occurs that results in any Material Indebtedness becoming due prior to its scheduled maturity or that enables or permits (after giving effect to the expiration of any grace or cure period set forth therein) the holder or holders of any such Material Indebtedness or any trustee or agent on its or their behalf to cause any such Material Indebtedness to become due, or to require the prepayment, repurchase, redemption or defeasance thereof, prior to its scheduled maturity; (vi) the Company or any of its Subsidiaries, pursuant to or within the meaning of Title 11, U.S. Code, or any similar Federal, foreign or state law for the relief of debtors (collectively, "Bankruptcy Law"), (A) commences a voluntary case, (B) consents to the entry of an order for relief against it in an involuntary case, (C) consents to the appointment of a receiver, trustee, assignee, liquidator or similar official (a "Custodian"), (D) makes a general assignment for the benefit of its creditors or (E) admits in writing that it is generally unable to pay its debts as they become due; (vii) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that (A) is for relief against the Company or any of its Subsidiaries in an involuntary case, (B) appoints a Custodian of the Company or any of its Subsidiaries or (C) orders the liquidation of the Company or any of its Subsidiaries; (viii) any representation or warranty made by the Company in any Transaction Document shall have been incorrect in a material way when made; (ix) the Company breaches in any material respect any covenant or other term or condition of any Transaction Document (other than covenants, terms or conditions, the breach of which constitutes an "Event of Default" under any other subsection of this Section 4(a)), provided, in the case of a breach of a covenant which is curable, that such breach continues for a period of at least fifteen (15) consecutive days after such notice is received by the Company specifying such breach if no more than one other such breach cured within such time period shall have occurred within twelve months of the date thereof. (b) Redemption Right. Promptly after the occurrence of an Event of Default, the Company shall deliver written notice thereof via facsimile and overnight courier (an "Event of Default Notice") to the Holders. At any time (i) after the earlier of (A) the Holders' receipt of an Event of Default Notice with respect to an Event of Default and (B) the Holders otherwise becoming aware of an Event of Default and (ii) during the continuance of such Event of Default, any Holder may require the Company to redeem all or any portion of this Note by delivering written notice thereof (the "Event of Default Redemption Notice") to the Company, which Event of Default Redemption Notice shall indicate the portion of this Note the Holder is electing to redeem. Each portion of this Note subject to redemption by the Company pursuant to this Section 4(b) shall be redeemed by the Company at a price equal to the greater of (i) the Conversion Amount to be redeemed and (ii) the product of (A) the Conversion Rate with respect to such Conversion Amount in effect at such time as the Holder delivers an Event of Default Redemption Notice and (B) the Closing Sale Price of the Common Stock on the date immediately preceding such Event of Default (the "Event of Default Redemption Price"). Redemptions required by this Section 4(b) shall be made in accordance with the provisions of Section 8. (5) RIGHTS UPON FUNDAMENTAL TRANSACTION. The Company shall not enter into or be party to a Fundamental Transaction unless (i) the Successor Entity assumes in writing all of the obligations of the Company under this Note in accordance with the provisions of this Section 5 and each other Transaction Document (as defined in the Securities Purchase Agreement) pursuant to written agreements in form and substance reasonably satisfactory to the Majority Holders and approved as such by the Majority Holders prior to such Fundamental Transaction, and (ii) the Successor Entity is a publicly traded corporation whose common stock is quoted on or listed for trading on an Eligible Market. Upon the occurrence of any Fundamental Transaction, the Successor Entity shall succeed to, and be substituted for (so that from and after the date of such Fundamental Transaction, the provisions of this Note referring to the "Company" shall refer instead to the Successor Entity), and may exercise every right and power of, the Company an d shall assume all of the obligations of the Company under this Note with the same effect as if such Successor Entity had been named as the Company herein. Upon consummation of the Fundamental Transaction, the Successor Entity shall deliver to the Holder confirmation that there shall be issued upon conversion of this Note at any time after the consummation of the Fundamental Transaction, in lieu of the shares of the Company's Common Stock (or other securities, cash, assets or other property) purchasable upon the conversion of the Notes prior to such Fundamental Transaction, such shares of stock, securities, cash, assets or any other property whatsoever (including warrants or other purchase or subscription rights) which the Holder would have been entitled to receive upon the happening of such Fundamental Transaction had this Note been converted immediately prior to such Fundamental Transaction, as adjusted in accordance with the provisions of this Note. The provisions of this Section shall apply similarly a nd equally to successive Fundamental Transactions and shall be applied without regard to any limitations, including as set forth in Section 3(d), on the conversion of this Note. (6) RIGHTS UPON ISSUANCE OF PURCHASE RIGHTS. If at any time the Company grants, issues or sells any Options, Convertible Securities or rights to purchase stock, warrants, securities or other property pro rata to all record holders of any class of Common Stock (the "Purchase Rights"), then the Holder will be entitled to acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which the Holder could have acquired if the Holder had held the number of shares of Common Stock acquirable upon complete conversion of this Note (without taking into account any limitations or restrictions on the convertibility of this Note) immediately before the date on which a record is taken for the grant, issuance or sale of such Purchase Rights, or, if no such record is taken, the date as of which the record holders of Common Stock are to be determined for the grant, issue or sale of such Purchase Rights. (7) RIGHTS UPON ISSUANCE OF OTHER SECURITIES. (a) Adjustment of Conversion Price upon Issuance of Common Stock. If and whenever on or after the Subscription Date, the Company issues or sells, or in accordance with this Section 7(a) is deemed to have issued or sold, except any such issuances or sales or deemed issuances or sales to Dolphin Direct Equity Partners, LP, any shares of Common Stock (including the issuance or sale of shares of Common Stock owned or held by or for the account of the Company, but excluding shares of Common Stock issued or sold or deemed to have been issued or sold by the Company in connection with any Excluded Security) for a consideration per share (the "New Securities Issuance Price") less than a price (the "Applicable Price") equal to the Conversion Price in effect immediately prior to such issue or sale (the foregoing a "Dilutive Issuance"), then immediately after such Dilutive Issuance, the Conversion Price then in effect shall be reduced to an amount equal to the New Securities Issuance Price. For purposes of deter mining the adjusted Conversion Price under this Section 7(a), the following shall be applicable: (i) Issuance of Options. If the Company in any manner grants or sells any Options and the lowest price per share for which one share of Common Stock is issuable upon the exercise of any such Option or upon conversion or exchange or exercise of any Convertible Securities issuable upon exercise of such Option is less than the Applicable Price, then such share of Common Stock shall be deemed to be outstanding and to have been issued and sold by the Company at the time of the granting or sale of such Option for such price per share. For purposes of this Section 7(a)(i), the "lowest price per share for which one share of Common Stock is issuable upon the exercise of any such Option or upon conversion or exchange or exercise of any Convertible Securities issuable upon exercise of such Option" shall be equal to the sum of the lowest amounts of consideration (if any) received or receivable by the Company with respect to any one share of Common Stock upon granting or sale of the Option, upon exercise of the Option and upon conversion or exchange or exercise of any Convertible Security issuable upon exercise of such Option. No further adjustment of the Conversion Price shall be made upon the actual issuance of such share of Common Stock or of such Convertible Securities upon the exercise of such Options or upon the actual issuance of such Common Stock upon conversion or exchange or exercise of such Convertible Securities. (ii) Issuance of Convertible Securities. If the Company in any manner issues or sells any Convertible Securities and the lowest price per share for which one share of Common Stock is issuable upon such conversion or exchange or exercise thereof is less than the Applicable Price, then such share of Common Stock shall be deemed to be outstanding and to have been issued and sold by the Company at the time of the issuance of sale of such Convertible Securities for such price per share. For the purposes of this Section 7(a)(ii), the "price per share for which one share of Common Stock is issuable upon such conversion or exchange or exercise" shall be equal to the sum of the lowest amounts of consideration (if any) received or receivable by the Company with respect to any one share of Common Stock upon the issuance or sale of the Convertible Security and upon the conversion or exchange or exercise of such Convertible Security. No further adjustment of the Conversion Price shall be made upon the actual iss uance of such share of Common Stock upon conversion or exchange or exercise of such Convertible Securities, and if any such issue or sale of such Convertible Securities is made upon exercise of any Options for which adjustment of the Conversion Price had been or are to be made pursuant to other provisions of this Section 7(a), no further adjustment of the Conversion Price shall be made by reason of such issue or sale. (iii) Change in Option Price or Rate of Conversion. If the purchase price provided for in any Options, the additional consideration, if any, payable upon the issue, conversion, exchange or exercise of any Convertible Securities, or the rate at which any Convertible Securities are convertible into or exchangeable or exercisable for Common Stock changes (excluding circumstances limited to where such purchase price, additional consideration or rate is only subject to prospective change) at any time, the Conversion Price in effect at the time of such change shall be adjusted to the Conversion Price which would have been in effect at such time had such Options or Convertible Securities provided for such changed purchase price, additional consideration or changed conversion rate, as the case may be, at the time initially granted, issued or sold. For purposes of this Section 7(a)(iii), if the terms of any Option or Convertible Security that was outstanding as of the Closing Date are changed in the manner de scribed in the immediately preceding sentence, then such Option or Convertible Security and the Common Stock deemed issuable upon exercise, conversion or exchange thereof shall be deemed to have been issued as of the date of such change. No adjustment shall be made if such adjustment would result in an increase of the Conversion Price then in effect. (iv) Calculation of Consideration Received. In case any Option is issued in connection with the issue or sale of other securities of the Company, together comprising one integrated transaction in which no specific consideration is allocated to such Options by the parties thereto, the Options will be deemed to have been issued for a consideration of $.01. If any Common Stock, Options or Convertible Securities are issued or sold or deemed to have been issued or sold for cash, the consideration received therefor will be deemed to be the net amount received by the Company therefor. If any Common Stock, Options or Convertible Securities are issued or sold for a consideration other than cash, the amount of the consideration other than cash received by the Company will be the fair value of such consideration, except where such consideration consists of securities, in which case the amount of consideration received by the Company will be the Closing Sale Price of such securities on the date of receipt. If any Common Stock, Options or Convertible Securities are issued to the owners of the non-surviving entity in connection with any merger in which the Company is the surviving entity, the amount of consideration therefor will be deemed to be the fair value of such portion of the net assets and business of the non-surviving entity as is attributable to such Common Stock, Options or Convertible Securities, as the case may be. The fair value of any consideration other than cash or securities will be determined jointly by the Company and the Majority Holders. If such parties are unable to reach agreement within ten (10) days after the occurrence of an event requiring valuation (the "Valuation Event"), the fair value of such consideration will be determined within five (5) Business Days after the tenth day following the Valuation Event by an independent, reputable appraiser jointly selected by the Company and the Majority Holders. The determination of such appraiser shall be deemed binding upon all parties absent manifest error and the fees and expenses of such appraiser shall be borne by the Company. (v) Record Date. If the Company takes a record of the holders of Common Stock for the purpose of entitling them (A) to receive a dividend or other distribution payable in Common Stock, Options or in Convertible Securities or (B) to subscribe for or purchase Common Stock, Options or Convertible Securities, then such record date will be deemed to be the date of the issue or sale of the Common Stock deemed to have been issued or sold upon the declaration of such dividend or the making of such other distribution or the date of the granting of such right of subscription or purchase, as the case may be. (b) Adjustment of Conversion Price upon Subdivision or Combination of Common Stock. If the Company at any time on or after the Subscription Date subdivides (by any stock split, stock dividend, recapitalization or otherwise) one or more classes of its outstanding shares of Common Stock into a greater number of shares, the Conversion Price in effect immediately prior to such subdivision will be proportionately reduced. If the Company at any time on or after the Subscription Date combines (by combination, reverse stock split or otherwise) one or more classes of its outstanding shares of Common Stock into a smaller number of shares, the Conversion Price in effect immediately prior to such combination will be proportionately increased. (c) Other Events. If any event occurs of the type contemplated by the provisions of this Section 7 but not expressly provided for by such provisions (including, without limitation, the granting of stock appreciation rights, phantom stock rights or other rights with equity features, other than pursuant to an Approved Stock Plan), then the Company's Board of Directors will make an appropriate adjustment in the Conversion Price so as to protect the rights of the Holder under this Note; provided that no such adjustment will increase the Conversion Price as otherwise determined pursuant to this Section 7. (d) This Note Deemed Outstanding. If during the period beginning on and including the Subscription Date and ending on the date immediately preceding the Issuance Date, the Company entered into, or in accordance with Section 7(a) would have been deemed to have entered into (had this Note been outstanding at such time), any Dilutive Issuance or if any of the events or actions contemplated by Sections 7(b) or (c) shall have occurred, then solely for purposes of determining any adjustment under this Section 7 as a result of such Dilutive Issuance, deemed Dilutive Issuance, action or event, this Note shall be deemed to have been outstanding at the time of each such Dilutive Issuance, deemed Dilutive Issuance, action or event. (e) Security. This Note is secured to the extent and in the manner set forth in the Security Agreement and the Pledge Agreements and is subordinated to the extent and in the manner set forth in the Subordination Agreement. (f) Non-circumvention. The Company hereby covenants and agrees that the Company will not, by amendment of its Certificate of Incorporation, Bylaws or through any reorganization, transfer of assets, consolidation, merger, scheme of arrangement, dissolution, issue or sale of securities, or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Note, and will at all times in good faith carry out all of the provisions of this Note and take all action as may be required to protect the rights of the Holder of this Note. (g) Reservation of Authorized Shares. (i) Reservation. The Company initially shall reserve out of its authorized and unissued Common Stock a number of shares of Common Stock for each of the Notes equal to 130% of the Conversion Rate with respect to the Conversion Amount of each such Note as of the Issuance Date. So long as any of the Notes are outstanding, the Company shall take all action necessary to reserve and keep available out of its authorized and unissued Common Stock, solely for the purpose of effecting the conversion of the Notes, 130% of the number of shares of Common Stock as shall from time to time be necessary to effect the conversion of all of the Notes then outstanding (the "Required Reserve Amount"). The initial number of shares of Common Stock reserved for conversions of the Notes and each increase in the number of shares so reserved shall be allocated pro rata among the holders of the Notes based on the principal amount of the Notes held by each holder at the Closing (as defined in the Securities Purchase Agreement) or increase in the number of reserved shares, as the case may be (the "Authorized Share Allocation"). In the event that a holder shall sell or otherwise transfer any of such holder's Notes, each transferee shall be allocated a pro rata portion of such holder's Authorized Share Allocation. Any shares of Common Stock reserved and allocated to any Person which ceases to hold any Notes shall be allocated to the remaining holders of Notes, pro rata based on the principal amount of the Notes then held by such holders. (ii) Insufficient Authorized Shares. If at any time while any of the Notes remain outstanding the Company does not have a sufficient number of authorized and unreserved shares of Common Stock to satisfy its obligation to reserve for issuance upon conversion of the Notes at least a number of shares of Common Stock equal to the Required Reserve Amount (an "Authorized Share Failure"), then the Company shall immediately take all action necessary to increase the Company's authorized shares of Common Stock to an amount sufficient to allow the Company to reserve the Required Reserve Amount for the Notes then outstanding. Without limiting the generality of the foregoing sentence, as soon as practicable after the date of the occurrence of an Authorized Share Failure, but in no event later than 90 days after the occurrence of such Authorized Share Failure, the Company shall hold a meeting of its shareholders for the approval of an increase in the number of authorized shares of Common Stock. In connection with such meeting, the Company shall provide each shareholder with a proxy statement and shall use its best efforts to solicit its shareholders' approval of such increase in authorized shares of Common Stock and to cause its board of directors to recommend to the shareholders that they approve such proposal. (8) HOLDER'S REDEMPTIONS. (a) Mechanics. The Company shall deliver the applicable Event of Default Redemption Price to the Holder within five Business Days after the Company's receipt of the Holder's Event of Default Redemption Notice in accordance with the terms hereof.
