The foregoing includes, without limitation, actions pending or threatened (or any basis therefor known to the Company) involving prior employment of any of the Company's employees or former employees or their obligations under any agreements with prior employers. The Company is not a party or subject to the provisions of any order, writ, injunction, judgment or decree of any court or governmental agency or instrumentality.

3.10 Title to Properties; Liens and Encumbrances. The Company has good and marketable title to its properties and assets and, with respect to the property and assets leased by the Company, holds valid leasehold interests therein, in each case subject to no mortgage, pledge, lien, security interest, conditional sale agreement, encumbrance or charge, except (i) tax, materialmen's or like liens for obligations not yet due or payable or being contested in good faith by appropriate proceedings, or (ii) liens arising from equipment loans entered into in the ordinary course of business.

3.11 Proprietary Information and Other Rights. The Company owns or has the right to use patents, patent applications, trademarks, service marks, trade names, copyrights, mask works, trade secrets, information, proprietary rights and processes (collectively, "Proprietary Information") necessary for its business as now conducted, and believes it can obtain, on commercially reasonable terms, any additional rights necessary or required for its business as presently proposed to be conducted without, except in the case of patents and patent applications, any conflict with or infringement of the rights of others. To the best of the Company's knowledge, it possesses no licenses, patents or patent applications which conflict with or infringe the rights of others. There are no outstanding options, licenses or agreements of any kind relating to its Proprietary Information, nor is the Company bound by or a party to any options, licenses or agreements of any kind with respect to the patents, patent applications, trademarks, service marks, trade names, copyrights, trade secrets, inventions, franchises, licenses, information, proprietary rights and processes of any other person or entity other than shrink wrap or preinstalled software licensed by the Company in the ordinary course of business. The Company has not received any communications alleging that the Company has violated or, by conducting its business as proposed, would violate any of the patents, trademarks, service marks, trade names, copyrights or trade proprietary rights of any other person or entity. To the best knowledge of the Company, none of its employees is obligated under any contract (including licenses, covenants or commitments of any nature) or other agreement, or subject to any judgment, decree or order of any court or administrative agency, that would interfere with the use of his or her best efforts to promote the interests of the Company or that would conflict with the Company's business as proposed to be conducted. Neither the execution nor delivery of this Agreement, the Articles of Amendment, or the Rights Agreement, nor the carrying on of the Company's business by the employees of the Company, nor the conduct of the Company's business as proposed, will, to the best of the Company's knowledge, conflict with or result in a breach of the terms, conditions or provisions of, or constitute a default under, any contract,

covenant or instrument under which any of such employees is now obligated. The Company does not believe nor does it have any reason to believe that it is or will be necessary to utilize any inventions of any of its employees (or people they currently intend to hire) made prior to the employment of any such person by the Company. Since its organization, the Company has taken reasonable security measures to protect the secrecy, confidentiality and value of its Proprietary Information from not being generally known or known by competitors.

Subject to the truth and accuracy of each Purchaser's representations set forth in this Agreement and the Subscription Agreement signed by each Purchaser (the "Subscription Agreement"), the offer, sale and issuance of the Shares, the Agent's Shares and the Conversion Shares as contemplated by this Agreement and the Articles of Amendment are exempt from the registration requirements of the Act, and from the qualification requirements of the California Corporate Securities Law of 1968, as amended, and of such other states as may have jurisdiction over these transactions.

3.13 Compliance with Other Instruments. The Company is not in any violation or default of any term of the Articles of Amendment pertaining to its Series A, Series B, or the Series C Preferred Stock, its Articles of Continuance, or its Bylaws, any material term of any material agreement to which the Company is a party, including its existing debt instruments, or any judgment, decree, order, statute, rule or regulation to which the Company is subject, that alone or in the aggregate would have a material adverse effect on the condition, financial or otherwise, or operations of the Company. Except as set forth in the Schedule of Exceptions, the issuance of the Shares and the Agent's Shares does not require the vote, approval or consent of the Company's shareholders or of any other party. The execution, delivery and performance of this Agreement, the Rights Agreement and the Articles of Amendment, and the consummation of the transactions contemplated hereby and thereby have not resulted and will not result in any violation or be in conflict with or constitute, with or without the passage of time and giving of notice, either a default under any such provision, instrument, judgment, order, writ, decree or contract or an event that results in the creation of any lien, charge or encumbrance upon any assets of the Company or the suspension, revocation, impairment, forfeiture, or nonrenewal of any material permit, license, authorization, or approval applicable to the Company, its business or operations or any of its assets or properties. The Company has avoided every condition, and has not performed any act, the occurrence of which would result in the Company's loss of any rights granted under any license, distribution or other agreement.

3.14 Employees. To the best of the Company's knowledge, no employee of the Company is in violation of any term of any employment contract, patent disclosure agreement, noncompetition agreement, or any restrictive covenant to a former employer relating to the right of any such employee to be employed by the Company because of the nature of the business conducted or presently proposed to be conducted by the Company.

3.15 Confidential Information Agreement. The Company has entered into a confidentiality agreement in a form previously provided to the Placement Agent's legal counsel with each officer, director, and key employee of the Company. All persons having access to the Company's Proprietary Information have executed and are bound by confidentiality agreements. The Company, after reasonable investigation, is not aware that any of its employees, officers or consultants are in violation thereof, and the Company will use its best efforts to prevent any such violation.

The Company is not aware that any officer or key employee, or that any group of key employees, intends to terminate their employment with the Company, nor does the Company have a present intention to terminate the employment of any of the foregoing.

4. Representations and Warranties of the Purchasers

Each Purchaser hereby represents and warrants, severally and not jointly, to the Company as follows:

4.1 No Registration. Purchaser understands that the Shares, Conversion Shares and the Agent's Shares have not been registered under the Act and are being offered and sold pursuant to an exemption from registration contained in the Act based in part upon each Purchaser's representations below, in the Subscription Agreement and otherwise herein.

4.2 Investment Experience. Purchaser or its professional advisor has substantial experience in evaluating and investing in private placement transactions of securities in companies similar to the Company, and is capable of evaluating the merits and risks of its investment in the Company and has the capacity to protect its own interests. Purchaser is an "Accredited Investor" as defined in the rules promulgated under the Act. Purchaser represents that it has not been organized for the purpose of acquiring the Shares, Conversion Shares or the Agent's Shares, unless the beneficial owners are Accredited Investors.

4.3 Access to Information. Purchaser has had full opportunity to ask questions and receive answers concerning the terms and conditions of the offering, sale and issuance of the Shares and the Agent's Shares; has had full access to the Company's officers and such other information concerning the Company as it has requested; and has received and read the Disclosure Documents and understands the risk factors set forth therein.

4.4 Investment. Purchaser is acquiring the Shares and/or the Agent's Shares to be issued and/or sold hereunder (and the Conversion Shares) for investment in its own account (or a trust account if Purchaser is a trustee), and not as a nominee or agent (except in the case of a custodian for a minor), and not with a view to or for sale in connection with the distribution thereof. Purchaser understands that it must bear the economic risk of this investment indefinitely unless the Shares, the Agent's Shares or the Conversion Shares are registered pursuant to the Act, or an exemption from such registration is available. Purchaser further understands that there is no assurance that any exemption from the Act will be available or, if available, that such exemption will allow Purchaser to dispose of or otherwise transfer any or all of the Shares, the Agent's Shares or the Conversion Shares under the circumstances, in the amounts or at the times Purchaser might propose.

4.5 Authorization. Purchaser has the full power, right and authority to execute and deliver this Agreement and the Rights Agreement, and to perform its obligations hereunder and thereunder. This Agreement and the Rights Agreement, when executed by Purchaser, will constitute valid and legally binding obligations of Purchaser, enforceable in accordance with their terms, subject to laws of general application relating to bankruptcy, insolvency, and the relief of debtors, and rules of law governing specific performance, injunctive relief and other equitable remedies. No consent, approval,

authorization, order, filing, registration or qualification of or with any court, governmental authority or third person is required to be obtained by Purchaser in connection with the execution and delivery of this Agreement and the Rights Agreement or the performance of Purchaser's obligations hereunder and thereunder. The execution, delivery and performance of this Agreement and the Rights Agreement and the consummation of the transactions contemplated herein and therein (including ownership of the Shares, the Conversion Shares and/or the Agent's Shares) by the Purchaser do not violate any provision of, or constitute, with or without the passage of time or the giving of notice, a material breach of or default under, any term, condition or provision of any agreement, indenture or other instrument to which the Purchaser is a party, or by which it or its properties or assets are bound, or of any order, judgment or decree against or binding upon the Purchaser.

4.6 Tax Advisors. Purchaser has reviewed with its own tax advisors the federal, state and local tax consequences of this investment, where applicable, and the transactions contemplated by this Agreement. Purchaser is relying solely on such advisors and not on any statements or representations of the Company or any of its agents and understands that Purchaser (and not the Company) shall be responsible for Purchaser's own tax liability that may arise as a result of this investment or the transactions contemplated by this Agreement.

4.7 Purchaser's Counsel. Purchaser acknowledges that it has had the opportunity to review this Agreement, the exhibits and the schedules attached hereto, the transactions contemplated herein, the Disclosure Documents, and any other information provided herein by Company with its own legal counsel and/or Placement Agent's legal counsel.

4.8 Resale Under Rule 144. Purchaser acknowledges that it is aware of Rule 144 promulgated under the Act, which permits limited public resales of securities acquired in a nonpublic offering, subject to the satisfaction of certain conditions. Purchaser understands that under Rule 144, except as otherwise provided by section (k) of that Rule, the conditions include, among other things: the availability of certain current public information about the issuer, the resale occurring not less than one year after the party has purchased and paid for the securities to be sold, and limitations on the amount of securities to be sold and the manner of sale. Purchaser acknowledges that, in the event all of the requirements of Rule 144 are not met, registration under the Act, compliance with the SEC's Regulation A or an exemption from registration will be required for any disposition of the Shares, the Conversion Shares and the Agent's Shares. Purchaser understands that, although Rule 144 is not exclusive, the SEC has expressed its opinion that persons proposing to sell restricted securities received in a private offering other than in a registered offering or pursuant to Rule 144 will have a substantial burden of proof in establishing that an exemption from registration is available for such offers or sales and that such persons do so at their own risk.

4.9 Residency. The residency of Purchaser (or, in the case of a partnership or corporation, such entity's principal place of business) is correctly set forth on the Purchaser Signature Page hereto.

4.10 Legend. It is understood that the certificates evidencing the Shares, Conversion Shares and the Agent's Shares may bear the following legend:

THE SECURITIES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), OR APPLICABLE STATE LAW, AND NO INTEREST THEREIN MAY BE SOLD, DISTRIBUTED, ASSIGNED, OFFERED, PLEDGED OR OTHERWISE TRANSFERRED UNLESS (i) THERE IS AN EFFECTIVE REGISTRATION STATEMENT UNDER THE ACT AND APPLICABLE STATE SECURITIES LAWS COVERING ANY SUCH TRANSACTION INVOLVING SAID SECURITIES, (ii) THIS CORPORATION RECEIVES AN OPINION OF LEGAL COUNSEL FOR THE HOLDER OF THESE SECURITIES STATING THAT SUCH TRANSACTION IS EXEMPT FROM REGISTRATION OR (iii) THIS CORPORATION OTHERWISE SATISFIES ITSELF THAT SUCH TRANSACTION IS EXEMPT FROM REGISTRATION.

RIGHTS AND PREFERENCES OF
SERIES C CONVERTIBLE
PREFERRED STOCK OF
SOLIGEN TECHNOLOGIES, INC.

9(d) The Series C Convertible Preferred Stock ("Series C Preferred Stock") shall consist of one million (1,000,000) shares having the following particular rights and preferences:

(i) Dividends.

Holders of shares of Series C Preferred Stock shall not be entitled to any fixed or guaranteed dividends, nor to any cumulative dividend rights, but shall be entitled to receive out of the earnings and assets of the Corporation only such dividends as may be lawfully declared on such dates or may be determined in the discretion of the Board of Directors. No dividend or other distribution whatsoever shall be declared or paid on Common Shares or Preferred Shares ranking junior to the rights of the Series C Preferred Stock unless a dividend or other distribution shall be simultaneously paid on each outstanding share of Series C Preferred Stock which is equal to or greater than the product of (i) the dividend or distribution proposed to be declared or paid on each share of Common Shares or such junior Preferred Shares (on an as-converted to Common Shares basis) times (ii) the number of Common Shares into which each such share of Series C Preferred Stock is then convertible under Subsection 9(d)(iii) below. In any event, no dividend or other distribution shall be paid at any time on Series C Preferred Stock, on any other class or series of Preferred Shares (other than "Series B Preferred Stock"), or on Common Shares which would have the effect of reducing the net assets of the Corporation below the aggregate preferential amount (determined in accordance with Subsection 9(d)(ii) below) payable to holders of Series C Preferred Stock upon liquidation or dissolution of the Corporation.

(ii) Liquidation.

(a) Liquidation Preferences. Upon liquidation or dissolution of the Corporation, whether voluntary or involuntary, each share of Series C Preferred Stock shall entitle its holder to receive, out of the assets of the Corporation available for distribution to shareholders, whether from capital, surplus or earnings, and before any distribution of such assets to the holders of Common Shares or Preferred Shares ranking junior to the rights of the Series C Preferred Stock, a liquidation preference of one dollar ($1.00) per share (as adjusted for stock splits, dividends, consolidations, recapitalizations and similar events), plus any unpaid dividends declared pursuant to Subsection 9(d)(i) above. If the assets of the Corporation available for distribution to shareholders are insufficient to satisfy in full the liquidation preferences for Series C Preferred Stock and all the other classes or series of Preferred Shares entitled to a stated liquidation preference, then the holders of Series A and Series B Preferred Stock shall share ratably in such distribution in proportion to their respective stated liquidation preferences, and within each such series, each holder shall be entitled to receive the same distribution for each share of such series. After setting apart or paying in full the liquidation preferences on Series A and Series B Preferred Stock, further distribution of the remaining available assets shall be made pro rata to the holders of Series C Preferred Stock. After setting apart or paying in full the liquidation preference on Series C Preferred Stock, further distribution of the remaining available assets shall be made pro rata to the holders of any other classes or series of Preferred Shares entitled to a stated preference on liquidation, and then pro rata to the holders of Common Shares.

(b) Deemed Liquidations. The sale of all or substantially all of the Corporation's assets, or the acquisition of the Corporation by another entity by means of merger, consolidation, share exchange, reorganization or otherwise, pursuant to which shares of the Corporation's capital stock are converted

into cash, securities or other property of the acquiring entity or any of its affiliates, shall be regarded as a liquidation within the meaning of this Subsection 9(d)(ii); provided, however, that each holder of Series C Preferred Stock shall have the right to elect the benefits of the provisions of Subsection 9(d)(iii) or other applicable conversion provisions in lieu of receiving payment of the liquidation preference in the event of the liquidation, dissolution or winding up of the Corporation pursuant to this Subsection 9(d)(ii); provided, further, that this provision shall not apply if the holders of the Corporation's voting capital stock immediately prior to such merger, consolidation, share exchange or reorganization beneficially own, directly or indirectly, more than fifty percent (50%) of the combined voting power of the capital stock of the corporation resulting from such merger, consolidation, share exchange or reorganization.

(c) Noncash Distribution. Whenever the distribution provided for in this Subsection 9(d)(ii) shall be payable in property other than cash, the value of such distribution shall be the fair market value of such property as determined in good faith by the Corporation's Board of Directors.

(iii) Conversion.

(a) Automatic Conversions. At any time or times, part or all of any holder's shares of Series C Preferred Stock may be converted into Common Shares at the conversion price then in effect, in the manner specified below, and upon delivery by the holder thereof of written notice of conversion to the Corporation at its principal business offices (or at the office of any transfer agent for shares of Series C Preferred Stock or Common Shares) specifying the number of such shares to be converted, accompanied by the certificate or certificates for the shares to be converted, duly endorsed in blank or accompanied by signed instruments appropriate for the transfer thereof. In addition, all of the outstanding shares of Series C Preferred Stock shall, at the election of the Corporation's Board of Directors, be automatically converted into Common Shares in the manner specified below upon the occurrence of either of the following events (an "Automatic Conversion Event"):

(1) Immediately prior to such time as the Corporation shall close a firm commitment underwritten public offering of Common Shares pursuant to a registration statement filed pursuant to the Securities Act of 1933, as amended, ("Securities Act") in which the Corporation receives gross proceeds of at least ten million dollars ($10,000,000) and at a price equal to or greater than one dollar ($1.00) per share (adjusted for stock splits, dividends, consolidations, recapitalizations, and similar events); or

(2) After one (1) year from the date that a share of Series C Preferred Stock is issued, when (a) the Common Shares shall have traded above one dollar ($1.00) per share (as adjusted for stock splits, dividends, consolidations, recapitalizations and similar events) for sixty (60) consecutive trading days on a national securities exchange or NASDAQ, or (b) the closing bid price for the Common Shares quoted by an established quotation service for over-the-counter securities shall be above one dollar ($1.00) per share (as adjusted for stock splits, dividends, consolidations, recapitalizations and similar events) for sixty (60) consecutive trading days; and the cumulative trading volume of the Common Shares during such sixty (60) consecutive trading days is equal to or greater than three million five hundred thousand (3,500,000) Common Shares, if traded on a national securities exchange, or five million (5,000,000) Common Shares, if traded on NASDAQ or traded over-the-counter.

(a) Conversion Procedures. The Common Shares (or other shares, securities or property) into which the outstanding shares of Series C Preferred Stock are convertible as computed in this Subsection 9(d)(iii) shall, promptly after delivery to the Corporation of written notice of any conversion election, or promptly after the occurrence of any Automatic Conversion Event, and upon surrender to the Corporation of the certificates representing the Series C Preferred Stock to be converted, duly endorsed in blank or accompanied by signed instruments appropriate for transfer, be issued and delivered as soon as practicable to the holders of Series C Preferred Stock in due and proper form, and

shall be fully paid and nonassessable; as to any portion of the shares so surrendered which are not subject to such conversion election, the Corporation shall promptly issue to the holder thereof a certificate in due and proper form representing the shares of Series C Preferred Stock which have not been so converted. Conversion shall be deemed to have been made at the close of business on the date the holder gave notice to the Corporation, or on the date that the Corporation's Board of Directors elected to declare an Automatic Conversion Event, irrespective of the date on which such surrender or issuance may occur, and as of such election date each such holder shall be deemed to have become the record holder of such respective number of Common Shares (or other shares, securities or property), and the Series C Preferred Stock so converted shall be deemed forthwith cancelled and shall not thereafter be deemed authorized or subject to reissuance. No adjustment shall be made in the number of Common Shares issuable upon conversion to reflect declared, but unpaid, dividends on Series C Preferred Stock, but such dividends for which the payment date has passed shall be paid in cash as of the date of conversion of the shares of Series C Preferred Stock as to which they are owing. The Corporation shall not be required to issue any fraction of Common Shares upon conversion of Series C Preferred Stock; if any fraction of Common Shares would, except for the foregoing clause, be issuable to any holder on the conversion of Series C Preferred Stock, the Corporation shall pay to each holder of such converted Series C Preferred Stock an amount in cash equal to the then current fair market value of such fractional interest.

(b) Conversion Rates. The number of Common Shares issuable with respect to any share of Series C Preferred Stock shall be determined by dividing one dollar ($1.00) by the conversion price then in effect at the time of conversion for such series which shall initially be ten cents ($0.10) per share (the "Series C Conversion Price"), and which shall thereafter be subject to adjustment from time to time as set forth herein.

(c) Adjustment of Series C Conversion Price Upon Issuance of Common Shares or Convertible Securities. Except as provided in Subsection 9(d)(iii)(e), if, after the first date that a share of Series C Preferred Stock is issued, the Corporation shall issue or sell, or, in accordance with Subsections 9(d)(iii)(d)(1) through 9(d)(iii)(d)(5), is deemed to have issued or sold any Common Shares, or any stock or security convertible into or exchangeable for Common Shares, without consideration or for a consideration per share less than the Series C Conversion Price in effect immediately prior to the time of such issue or sale or deemed issuance or sale, then, forthwith upon each such issue or sale or deemed issuance or sale, the Series C Conversion Price shall be reduced to the price determined by dividing (i) an amount equal to the sum of (x) the number of Common Shares of the Corporation outstanding immediately prior to such issue or sale (including the number of Common Shares issuable pursuant to exercise of all outstanding options and warrants and the conversion of all of the outstanding Preferred Shares at the then existing conversion prices) multiplied by the then existing Series C Conversion Price plus (y) the consideration, if any, received by the Corporation upon such issue or sale, by (ii) the sum of the number of Common Shares outstanding immediately after such issue or sale (including the Common Shares issuable pursuant to conversion or exchange of the securities or stock issued or sold in such issue or sale) plus the number of Common Shares issuable pursuant to exercise of all outstanding options and warrants and the conversion of all of the outstanding Preferred Shares at the conversion prices existing before such issue or sale.

For purposes of this Subsection 9(d)(iii)(d), the following Subsections 9(d)(iii)(d)(1) to 9(d)(iii)(d)(5) shall also be applicable:

(1) Issuance of Rights or Options. In case at any time the Corporation shall in any manner grant (whether directly or by assumption in a merger or otherwise) any options, warrants or other rights to subscribe for or to purchase Common Shares or any stock or security convertible into or exchangeable for Common Shares (such options, warrants and rights being called "Options" and such convertible or exchangeable stock or securities being called "Convertible Securities") whether or not such Options or the right to convert or exchange any such Convertible Securities are

immediately exercisable, and the price per share for which Common Shares are issuable upon the exercise of such Options or upon the conversion or exchange of such Convertible Securities (determined by dividing (i) the total amount, if any, received or receivable by the Corporation as consideration for the granting of such Options, plus the minimum aggregate amount of additional consideration payable to the Corporation upon the exercise of all such Options, plus, in the case of such Options which relate to Convertible Securities, the minimum aggregate amount of additional consideration, if any, payable upon the issue or sale of such Convertible Securities and upon the conversion or exchange thereof, by (ii) the Common Shares issuable upon the exercise of such Options or upon the conversion or exchange of all such Convertible Securities issuable upon the exercise of such Options) shall be less than the Series C Conversion Price in effect immediately prior to the time of the granting of such Options, then the total maximum number of Common Shares issuable upon the exercise of such Options or upon conversion or exchange of the total maximum amount of such Convertible Securities shall be deemed to have been issued for such price per share as of the date of granting of such Options. Except as otherwise provided in Subsection 9(d)(iii)(d)(3), no adjustment of the Series C Conversion Price shall be made upon the actual issuance of the Common Shares or Convertible Securities upon exercise of such Options or upon the actual issuance of such Common Shares upon conversion or exchange of such Convertible Securities.

(2) Issuance of Convertible Securities. In case the Corporation shall in any manner issue (whether directly or by assumption in a merger or otherwise) or sell any Convertible Securities, whether or not the rights to exchange or convert any such Convertible Securities are immediately exercisable, and the price per share for which the Common Shares are issuable upon such conversion or exchange (determined by dividing (i) the total amount received or receivable by the Corporation as consideration for the issuance or sale of such Convertible Securities, plus the minimum aggregate amount of additional consideration, if any, payable to the Corporation upon the conversion or exchange thereof, by (ii) the total maximum number of Common Shares issuable upon the conversion or exchange of all such Convertible Securities) shall be less than the Series C Conversion Price in effect immediately prior to the time of such issue or sale, then the Common Shares issuable upon conversion or exchange of all such Convertible Securities shall be deemed to have been issued for such price per share as of the date of the issuance or sale of such Convertible Securities and thereafter shall be deemed to be outstanding, provided that (a) except as otherwise provided in Subsection 9(d)(iii)(d)(3), no adjustment of the Series C Conversion Price shall be made upon the actual issuance of such Common Shares upon conversion or exchange of such Convertible Securities and (b) if any such issuance or sale of such Convertible Securities is made upon exercise of any Options to purchase any such Convertible Securities for which adjustments of the Series C Conversion Price have been or are to be made pursuant to other provisions of this Subsection 9(d)(iii)(d), no further adjustment of the Series C Conversion Price shall be made by reason of such issuance or sale.

(3) Change in Option Price or Conversion Rate. Upon the happening of any of the following events, namely, if the purchase price provided for in any Option referred to in Subsection 9(d)(iii)(d)(1), or the rate at which Convertible Securities referred to in Subsection 9(d)(iii)(d)(2) are convertible into or exchangeable for Common Shares shall change at any time (including, but not limited to, changes under or by reason of provisions designed to protect against dilution), the Series C Conversion Price in effect at the time of such event shall forthwith be readjusted to the Series C Conversion Price which would have been in effect at such time had such Options or Convertible Securities still outstanding provided for such changed purchase price, additional consideration or conversion rate, as the case may be, at the time initially granted, issued or sold; and on the expiration of any such Option or termination of any such right to convert or exchange such Convertible Securities, the Series C Conversion Price then in effect hereunder shall forthwith be increased to the Series C Conversion Price which should have been in effect at the time of such

expiration or termination had such Option or Convertible Securities, to the extent outstanding immediately prior to such expiration or termination, never been issued.

(4) Consideration for Shares. In case any Common Shares, Options or Convertible Securities shall be issued or sold for cash, the consideration received therefor shall be deemed to be the amount received by the Corporation therefor, without deduction therefrom of any expenses incurred or any underwriting commissions or concessions paid or allowed by the Corporation in connection therewith. In case Common Shares, Options or Convertible Securities shall be issued or sold for a consideration in whole or in part other than cash, the amount of the consideration other than cash received by the Corporation shall be deemed to be the fair market value of such consideration as determined in good faith by the Board of Directors of the Corporation, without deduction of any expenses incurred or any underwriting commissions or concessions paid or allowed by the Corporation in connection therewith. In case any Options shall be issued in connection with the issuance or sale of other securities of the Corporation, together comprising one integral transaction in which no specific consideration is allocated to such Options by the parties thereto, such Options shall be deemed to have been issued for such consideration as determined in good faith by the Board of Directors of the Corporation.

(5) Record Date. In case the Corporation shall take a record of the holders of its Common Shares for the purpose of entitling them (i) to receive a dividend or other distribution payable in Common Shares, Options or Convertible Securities, or (ii) to subscribe for or purchase Common Shares, Options or Convertible Securities, then such record date shall be deemed to be the date of the issuance or sale of the Common Shares 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, and, in each such case, the number of Common Shares into which shares of Series C Preferred Stock may be converted shall be increased in proportion to the increase (through such dividend or distribution) in the number of outstanding Common Shares, by reducing the Series C Conversion Price in the same proportion.

(d) Certain Issues of Common Shares Excepted. Anything herein to the contrary notwithstanding, the Corporation shall not be required to make any adjustment of the Series C Conversion Price pursuant to Subsection 9(d)(iii)(d) in the case of the issuance of: (i) up to an aggregate of ten million five hundred thousand (10,500,000) Common Shares (appropriately adjusted for stock splits, dividends, consolidations, recapitalizations and similar events), pursuant to the Corporation's 1993 Stock Option Plan, as amended, unless the director representing the Series B Preferred Stock or the Series C Preferred Stock votes in favor of the issuance of Common Shares pursuant to such employment compensation plan beyond the aforementioned limit; and (ii) such other securities as the holders of sixty-six and two-thirds percent (66²/3%) of the then outstanding shares of Series C Preferred Stock shall agree in writing may be issued without causing an adjustment in the Series C Conversion Price.

(e) Subdivision or Combination of Common Shares. In case the Corporation shall at any time subdivide (by any stock split, stock dividend or otherwise) its outstanding Common Shares into a greater number of shares, without making a corresponding subdivision of the outstanding shares of Series C Preferred Stock, then the Series C Conversion Price in effect immediately prior to such subdivision shall be proportionately reduced. Conversely, in case the outstanding Common Shares shall be combined into a smaller number of shares without a corresponding adjustment to the number of outstanding shares of Series C Preferred Stock, then the Series C Conversion Price in effect immediately prior to such combination shall be proportionately increased.

(f) Other Distributions. If the Corporation shall declare a distribution payable in securities of other persons (including, but not limited to, spin-offs of a business whereby, for example, an asset of the Corporation is contributed to a subsidiary which is spun-off to the Corporation's shareholders), evidences of indebtedness issued by this Corporation or other persons, assets (excluding cash dividends)

or options or rights not referred to in Subsection 9(d)(iii)(h), then, in each such case for the purpose of this Subsection 9(d)(iii)(g), the holders of the Series C Preferred Stock shall be entitled to a proportionate share of any such distribution as though they were the holders of the number of Common Shares into which their shares of Series C Preferred Stock are convertible as of the record date fixed for the determination of the holders of Common Shares entitled to receive such distribution.

(g) Reorganization or Reclassification. If any capital reorganization or reclassification of the capital stock of the Corporation shall be effected in such a way that holders of Common Shares shall be entitled to receive stock, securities or assets with respect to or in exchange for Common Shares, then, as a condition of such reorganization or reclassification, lawful and adequate provisions shall be made whereby each holder of a share or shares of Series C Preferred Stock shall thereupon have the right to receive, upon the basis and upon the terms and conditions specified herein and in lieu of the Common Shares immediately theretofore receivable upon the conversion of such shares of Series C Preferred Stock, such shares of stock, securities or assets as may be issued or payable with respect to or in exchange for a number of outstanding shares of such Series C Preferred Stock equal to the number of Common Shares immediately theretofore receivable upon such conversion had such reorganization or reclassification not taken place, and in any such case appropriate provisions shall be made with respect to the rights and interests of such holder to the end that the provisions hereof shall thereafter be applicable, as nearly as may be, in relation to any shares of stock, securities or assets thereafter deliverable upon the exercise of such conversion rights.

(h) Notice of Adjustment. Upon any adjustment of the Series C Conversion Price, then, and in each such case, the Corporation shall give written notice thereof as soon as practicable thereafter, by first class, registered or certified mail, postage prepaid, return receipt requested, or by telecopier (to be promptly followed by notice sent by registered or certified mail, return receipt requested, as set forth above), addressed to each holder of shares of Series C Preferred Stock, as the case may be, at the address of such holder as shown on the books of the Corporation, which notice shall state the conversion rate resulting from such adjustment and the manner in which such calculation was made.

(i) Shares to be Reserved. The Corporation will at all times reserve and keep available out of its authorized, but unissued, Common Shares, solely for the purpose of issuance upon the conversion of Series C Preferred Stock as herein provided, such number of Common Shares as shall then be issuable upon the conversion of all outstanding shares of Series C Preferred Stock. The Corporation covenants that all Common Shares which shall be so issued shall be duly and validly issued, fully paid, nonassessable and free from all taxes, liens and charges with respect to the issue thereof. The Corporation will take such action as may be necessary to assure that all Common Shares may be so issued without violation of any applicable law or regulation, or of any requirement of any securities exchange upon which the Common Shares may be listed.

(j) Issue Tax. The issuance of certificates for Common Shares upon conversion of Series C Preferred Stock shall be made without charge to the holders thereof for any issuance tax in respect thereof, provided that the Corporation shall not be required to pay any tax which may be payable in respect of any transfer involved in the issuance and delivery of any certificate in a name other than that of the holder (or its affiliate) of the Series C Preferred Stock.

(iv) Voting.

(a) Shareholder Voting. Holders of the outstanding Series C Preferred Stock shall be entitled to cast, on all matters submitted to a vote of all of the shareholders of the Corporation (including in the election of directors, except as set forth in Subsections 9(b)(iv), 9(b)(v), 9(c)(iv) and 9(c)(v)) and on which shareholders are entitled to vote under the provisions of the Wyoming Business Corporation Act, that number of votes equal to the number of Common Shares into which such outstanding Series C Preferred Stock is then convertible under Subsection 9(d)(iii) at the record date for the determination of shareholders entitled to vote on such matter, and with respect to such vote, shall be entitled, notwithstanding any provision hereof, to notice of any stockholders' meeting in accordance with the Bylaws of this Corporation. Fractional votes shall not, however, be permitted and any fractional voting rights resulting from the aforementioned formula (after aggregating all shares into which shares of Series C Preferred Stock held by each holder could be converted) shall be rounded to the nearest whole number (with one-half rounded upward to one). In addition to their right to elect the Series C Director, as provided below, and except as set forth in Subsections 9(b)(iv), 9(b)(v), 9(c)(iv) and 9(c)(v), holders of Series C Preferred Stock shall vote together with the holders of Series A Preferred Stock, Series B Preferred Stock and Common Shares on all such matters except as otherwise provided herein.

(b) Series B Director/Series C Director.

(1) As long as the holders of Series B Preferred Stock have the right to elect the Series B Director under Subsection 9(c)(iv)(b), and such holders exercise such right, the holders of Series C Preferred Stock shall not have any right to elect a specific member to the Corporation's Board of Directors to represent the holders of Series C Preferred Stock (the "Series C Director").

(2) For so long as more than fifty percent (50%) of all shares of Series C Preferred Stock issued by the Corporation shall be outstanding, and if the holders of Series B Preferred Stock no longer have the right to elect the Series B Director, or if such holders do not exercise such right, then the holders of the Series C Preferred Stock, voting as a separate voting group, shall be entitled to elect one (1) Series C Director at the annual meeting of the Corporation's shareholders and otherwise if there is a vacancy of the directorship held by the Series C Director. If the aforementioned minimum outstanding shares requirement has been met, then at any meeting held for the purpose of electing directors, the presence in person or by proxy of the holders of a majority of the outstanding shares of Series C Preferred Stock shall constitute a quorum of such shares for the election of the Series C Director to be elected. Once elected, the Series C Director shall have a fiduciary obligation to all shareholders pursuant to the Wyoming Business Corporation Act.

(3) Except as otherwise provided by law, the Series C Director shall be elected by a majority of the votes cast by the Series C Preferred Stock at a meeting of shareholders at which a quorum is present. Provided that the minimum outstanding shares requirement in Subsection 9(d)(iv)(b)(2) is met, any vacancy of the Series C Director shall be filled only by the vote or written consent of the holders of a majority of the then outstanding shares of Series C Preferred Stock. Any Series C Director may be removed from office, whether with or without cause, only by the vote or written consent of the holders of a majority of the then outstanding shares of Series C Preferred Stock.

(c) Noncompliance. If the Corporation fails to comply with Subsections 9(d)(iv)(b), then, in addition to any other legal remedies available to the holders of the Series C Preferred Stock, the number of directors that the holders of the then outstanding shares of Series C Preferred Stock shall be entitled to elect under Subsection 9(d)(iv)(b) shall be increased to a total of three (3) directors, effective immediately upon such noncompliance and for as long as such noncompliance exists.

(v) Restrictions.

For so long as more than fifty percent (50%) of all shares of Series C Preferred Stock issued by the Corporation shall be outstanding, except where the vote or written consent of the holders of a greater number of shares of the Corporation is required by law or by the Articles of Incorporation, and in addition to any other vote required by law or the Articles of Incorporation, the Corporation will not take any of the following actions without the approval of the holders of at least sixty-six and two-thirds percent (66²/3%) of the then outstanding shares of Series C Preferred Stock, given in writing or by vote at a meeting, consenting or voting (as the case may be) as a separate voting group:

(a) Engage in any transaction or a series of transactions resulting in a "Change of Control ("Change in Control" shall mean and occur when (i) any "person" as such term is defined in Section 3(a)(9) and 13(d)(3) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), other than a trustee or other fiduciary holding securities under an employee benefit plan of the Corporation, is or becomes a beneficial owner (within the meaning of rule 13d-3 promulgated under the Exchange Act), directly or indirectly, of securities of the Corporation, representing fifty-one percent (51%) or more of the combined voting power of the Corporation's then outstanding securities; or (ii) the shareholders of the Corporation approve a reorganization, merger or consolidation of the Corporation with any other corporation or entity, other than a reorganization, merger or consolidation which would result in the voting securities of the Corporation outstanding immediately prior thereto continuing to represent (either by remaining outstanding or by being converted into voting securities of the surviving entity) at least fifty-one percent (51%) of the combined voting power of the voting securities of the Corporation or such surviving entity outstanding immediately after such reorganization, merger or consolidation; or (iii) the shareholders of the Corporation approve a plan of complete liquidation, dissolution or winding up of the Corporation or an agreement for the sale or disposition by the Corporation of all or substantially all of its assets);

(b) Pay or declare any dividends or make any distribution with respect to any holder of Common or Preferred Shares junior to the Series C Preferred Stock;

(d) Enter into any transactions with any of its affiliates, unless each such transaction is on terms at least as favorable as those available to the Corporation from disinterested third parties and such transaction is approved by the Board of Directors, including the Series B Director or Series C Director (provided that the approval of the Series B Director or the Series C Director is not required if such director is an interested party in such transaction); or

(e) Change the rights, preferences, privileges or restrictions of any shares of Series C Preferred Stock.

(vi) Sinking Fund.

There shall be no sinking fund provision for the payment of dividends, liquidation preferences, or redemption of the shares of Series C Preferred Stock.

(vii) Redemption of Series C Preferred Stock.

(a) Mandatory Redemption. If a Change of Control (as defined in Subsection 9(d)(v)(a)) has occurred, the Corporation shall offer to redeem all of the outstanding shares of Series C Preferred Stock for cash, at a price per share equal to one hundred and fifty percent (150%) of the liquidation preference for Series C Preferred Stock under Subsection 9(d)(ii)(a), plus any declared, but unpaid, dividends under Subsection 9(d)(i), by providing each holder of Series C Preferred Stock with written notice of such redemption ("Redemption Offer Notice") within thirty (30) days of such Change of Control. If any holder of Series C Preferred Stock does not elect in writing within twenty (20) days of

the date of the Redemption Offer Notice ("Election Period") to have all of such holder's shares of Series C Preferred Stock redeemed, then, with respect to the holder's unredeemed shares of Series C Preferred Stock, such holder's mandatory redemption rights hereunder shall terminate as to such Change of Control event. If any of the holders of the outstanding shares of Series C Preferred Stock elects redemption before the expiration of the Election Period, then the Corporation shall notify such holder of the redemption within ten (10) days following the end of the Election Period ("Mandatory Redemption Notice"). Within ten (10) days of the receipt of the Mandatory Redemption Notice, such holder shall surrender to the Corporation the certificate(s) representing such shares of Series C Preferred Stock to be redeemed duly endorsed for transfer to this Corporation, and upon receipt of such certificates, the Corporation shall pay the redemption price for such shares to the order of the person whose name appears on such certificate(s) as the owner thereof, and each surrendered certificate shall be cancelled. As to any portion of the shares of Series C Preferred Stock so surrendered which are not subject to such holder's redemption election, the Corporation shall promptly issue to the person whose name appears on such certificate(s) a certificate in due and proper form representing the shares of Series C Preferred Stock which have not been redeemed. When the redemption price is paid, all rights in respect of the redeemed shares of Series C Preferred Stock shall cease and terminate, and such shares shall no longer be deemed to be authorized, outstanding, or available for reissuance, whether or not the certificates representing such shares have been received by the Corporation.

(b) Optional Redemption. If from and after two years of the date the first share of Series C Preferred Stock is sold and issued by the Corporation, the Common Shares shall have traded above fifty cents ($0.50) per share (as adjusted for stock splits, dividends, consolidations, recapitalizations and similar events) for sixty (60) consecutive days on a national securities exchange or NASDAQ, or the closing bid price quoted by an established quotation service for over-the-counter securities shall be above fifty cents ($0.50) for sixty (60) consecutive days, then the Corporation shall have the right, but not the obligation, to redeem all of the outstanding shares of Series C Preferred Stock for cash, at a price per share equal to one hundred and fifty percent (150%) of the liquidation preference for Series C Preferred Stock under Subsection 9(d)(ii)(a), plus any declared, but unpaid, dividends under Subsection 9(d)(i), by providing each holder of Series C Preferred Stock with written notice of such redemption not less than thirty (30) days prior to the scheduled date of redemption ("Optional Redemption Notice"). In the event of such redemption, and prior to the scheduled date of redemption, holders of Series C Preferred Stock shall surrender to the Corporation the certificate(s) representing such shares of Series C Preferred Stock to be redeemed duly endorsed for transfer to this Corporation, and upon receipt of such certificates, the Corporation shall pay the redemption price for such shares to the order of the person whose name appears on such certificate(s) as the owner thereof, and each surrendered certificate shall be cancelled. When the redemption price is paid, all rights in respect of the redeemed shares of Series C Preferred Stock shall cease and terminate, and such shares shall no longer be deemed to be authorized, outstanding or available for reissuance, whether or not the certificates representing such shares have been received by the Corporation. Nothing herein contained in this Subsection 9(d)(vii)(b) shall prohibit any holder of Series C Preferred Stock from electing the benefits of the provisions of Subsection 9(d)(iii) or other applicable conversion provisions prior to the scheduled date of redemption.

(c) Noncompliance/Conversion Price Adjustment. If (i) any of the holders of Series C Preferred Stock elects redemption under Subsection 9(d)(vii)(a) and complies with the provisions therein; (ii) the Corporation fails to redeem any of such holder's shares of Series C Preferred Stock as required therein; and (iii) such failure is not due to the failure of the holders of Series B Preferred Stock to approve such redemption under Subsection 9(c)(v)(c), then the Series C Conversion Price for those unredeemed shares of Series C Preferred Stock shall be reduced by one percent (1%) on the seventh (7^th) day following such noncompliance and by an additional one percent (1%) every seven (7) days thereafter until the redemption has been made.

(viii) Noncompliance with Registration Rights/Conversion Price Adjustment.

If all of the conditions set forth in Section 5.1 of that certain Investor Rights Agreement between the Corporation and the holders of Series C Preferred Stock have been met (including, but not limited to, the absence of an underwriter's exclusion under Section 5.1(c) of such Investor Rights Agreement) and the Corporation fails to comply with the registration rights provisions set forth in such Section 5.1, then the Series C Conversion Price shall be reduced by one percent (1%) on the seventh (7^th) day following such noncompliance and by an additional one percent (1%) every seven (7) days thereafter until the registration of such shares has been made.

THIS INVESTOR RIGHTS AGREEMENT (the "Agreement") is made as of this 22nd day of February 2001, by and among Soligen Technologies, Inc., a Wyoming corporation (the "Company"), and the parties named on Exhibit A hereto.

A. The Company proposes to enter into a Series C Preferred Stock Purchase Agreement to be dated the date hereof (the "Series C Purchase Agreement") pursuant to which the Company shall sell up to one million (1,000,000) shares of its Series C Convertible Preferred Stock ("Series C Preferred") to the purchasers named therein (the "Series C Purchasers"), and issue in the aggregate to the Company's Placement Agent, ▇.▇. ▇▇▇▇▇▇ & Co., Inc. and its designees, three hundred ninety-three thousand one hundred sixty-seven (393,167) shares of the Company's Common Stock in such closing ("Agent's Shares"); and

B. In order to induce the Series C Purchasers to enter into the Series C Purchase Agreement, the Company has agreed to this Agreement.

NOW, THEREFORE, in consideration of the mutual promises and covenants hereinafter set forth, all parties hereto agree as follows:

1. Certain Definitions.

All capitalized terms used and not otherwise defined herein shall have the meanings given them in the Series C Purchase Agreement. As used in this Agreement, the following terms shall have the following respective meanings:

"Commission" shall mean the Securities and Exchange Commission or any other federal agency at the time administering the Securities Act.

"Common Stock" shall mean the Company's Common Stock.

"Conversion Stock" means the Common Stock issued or issuable pursuant to conversion of the Preferred Stock.

"Holder" shall mean (i) the persons listed on Exhibit A who hold Registrable Securities, and (ii) any person holding Registrable Securities to whom the rights under this Agreement have been transferred in accordance with Section 5.7 hereof.

The terms "register," "registered" and "registration" refer to a registration effected by preparing and filing a registration statement in compliance with the Securities Act, as hereinafter defined, and the declaration or ordering of the effectiveness of such registration statement.

"Registration Expenses" shall mean all expenses, except as stated in Section 5.2 hereof, incurred by the Company in complying with Section 5.1 hereof, including, without limitation, all registration, qualification and filing fees, printing expenses, escrow fees, fees and disbursements of counsel for the Company, blue sky fees and expenses, and the expense of any special audits incident to or required by any such registration (but excluding (i) the compensation of regular employees of the Company which shall be paid in any event by the Company and (ii) Selling Expenses) and, up to $20,000 of fees and expenses of one counsel for all Holders as appointed by the Holders and reasonably acceptable to the Company.

"Restricted Securities" shall mean the securities of the Company required to bear the legend set forth in Section 3 hereof.

"Securities Act" shall mean the Securities Act of 1933, as amended, and the rules and regulations of the Commission thereunder, all as the same shall be in effect at the time.

"Selling Expenses" shall mean all underwriting discounts, selling commissions and stock transfer taxes applicable to the securities registered by the Holders and, except as set forth under "Registration Expenses", all fees and disbursements of counsel for any Holder.

2. Restrictions on Transferability.

The Conversion Stock and the Agent's Shares and any other securities issued in respect of the Conversion Stock or Agent's Shares upon any stock split, stock dividend, recapitalization, merger, consolidation or similar event, shall not be sold, assigned, transferred or pledged except upon the conditions specified in this Agreement, which conditions are intended to ensure compliance with the provisions of the Securities Act. Each Holder will cause any proposed purchaser, assignee, transferee, or pledgee of any such shares held by the Holder to agree to take and hold such securities subject to the provisions and upon the conditions specified in this Agreement.

3. Restrictive Legend.

Each certificate representing (i) the Conversion Stock, and the Agent's Shares and (ii) any other securities issued in respect of the Conversion Stock and the Agent's Shares upon any stock split, stock dividend, recapitalization, merger, consolidation or similar event, shall (unless otherwise permitted by the provisions of Section 4 below) be stamped or otherwise imprinted with a legend in substantially the following form (in addition to any legend required under applicable state securities laws):

THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE SECURITIES LAWS, AND HAVE BEEN ACQUIRED FOR INVESTMENT AND NOT WITH A VIEW TO, OR IN CONNECTION WITH, THE SALE OR DISTRIBUTION THEREOF. SUCH SHARES MAY NOT BE SOLD OR TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION UNLESS THE COMPANY RECEIVES AN OPINION OF COUNSEL REASONABLY ACCEPTABLE TO IT STATING THAT SUCH SALE OR TRANSFER IS EXEMPT FROM THE REGISTRATION REQUIREMENTS OF SAID ACT. COPIES OF THE AGREEMENTS COVERING THE PURCHASE OF THESE SHARES AND RESTRICTING THEIR TRANSFER MAY BE OBTAINED AT NO COST BY WRITTEN REQUEST MADE BY THE HOLDER OF RECORD OF THIS CERTIFICATE TO THE SECRETARY OF THE COMPANY AT THE PRINCIPAL EXECUTIVE OFFICES OF THE COMPANY.

Each Holder consents to the Company's making a notation on its records and giving instructions to any transfer agent in order to implement the restrictions on transfer established in this Agreement.

4. Notice of Proposed Transfers.

The Holder of each certificate representing Restricted Securities by acceptance thereof agrees to comply in all respects with the provisions of this Section 4. Prior to any proposed sale, assignment, transfer or pledge of any Restricted Securities (other than (i) a transfer not involving a change in beneficial ownership, (ii) in transactions involving the distribution without consideration of Restricted Securities to any partners or members, or retired partners or members, or to the estate of a transferor (iii) any transfer to any affiliate controlled by, under common control or under common investment management with, any transferor or (iv) in transactions in compliance with Rule 144), unless there is in effect a registration statement under the Securities Act covering the proposed transfer, the holder thereof shall give written notice to the Company of such holder's intention to effect such transfer, sale, assignment or pledge. Each such notice shall describe the manner and circumstances of the proposed transfer, sale, assignment or pledge in sufficient detail, and shall be accompanied, at such holder's expense by either (i) written opinion of legal counsel, who shall be, and whose legal opinion shall be, reasonably satisfactory to the Company addressed to the Company, to the effect that the proposed transfer of the Restricted Securities may be effected without registration under the Securities Act, or (ii) a "no action" letter from the Commission to the effect that the transfer of such securities without registration will not result in a recommendation by the staff of the Commission that action be taken with respect thereto, whereupon the holder of such Restricted Securities shall be entitled to transfer such Restricted Securities in accordance with the terms of the notice delivered by the holder to the Company. It is agreed that the Company will not request an opinion of counsel for the holder for transactions made in reliance on Rule 144 under the Securities Act except in unusual circumstances, the existence of which shall be promptly determined in good faith by the Board of Directors of the Company. Each certificate evidencing the Restricted Securities transferred as above provided shall bear, except if such transfer is made pursuant to Rule 144, the appropriate restrictive legend set forth in Section 3 above, except that such certificate shall not bear such restrictive legend if in the opinion of counsel for such holder (if required above) and the Company such legend is not required in order to establish compliance with any provision of the Securities Act.

5. Registration.

5.1 Company Registration.

(a) Notice of Registration. If at any time, or from time to time, the Company shall determine to register any of its equity securities, either for its own account or the account of a security holder or holders, other than (i) a registration relating solely to employee benefit plans, (ii) a registration relating solely to a Rule 145 transaction, the Company will:

(1) promptly give to each Holder written notice thereof; and

(2) include in such registration (and any related qualification under blue sky laws or other compliance), and in any underwriting involved therein, all the Registrable Securities specified in a written request or requests, made within twenty (20) days after receipt of such written notice from the Company, by any Holder.

(b) Underwriting. If the registration of which the Company gives notice is for a registered public offering involving an underwriting, the Company shall so advise the Holders as a part of the written notice given pursuant to Section 5.1(a)(1). In such event, the right of any Holder to registration pursuant to this Section 5.1 shall be conditioned upon such Holder's participation in

such underwriting, and the inclusion of Registrable Securities in the underwriting shall be limited to the extent provided herein.

(c) All Holders proposing to distribute their securities through such underwriting shall (together with the Company and the other holders distributing their securities through such underwriting) enter into an underwriting agreement in customary form with the managing underwriter selected for such underwriting by the Company. Notwithstanding any other provision of this Section 5.1, if the managing underwriter determines that marketing factors require a limitation of the number of shares to be underwritten, the managing underwriter may exclude some or all of the Registrable Securities, or securities of other holders of registration rights, other than persons exercising demand registration rights, from such registration. The Company shall advise all Holders, and other holders distributing their securities through such underwriting of any limits imposed on their participation in the underwriting as provided in this Section 5.1. The number of shares of Registrable Securities, or securities of other holders of registration rights other than persons exercising demand registration rights, that may be included in the registration and underwriting in accordance with this Section 5.1 shall be allocated among all the Holders and such other holders of securities not exercising demand registration rights pro rata based on the number of Registrable Securities or securities held by the Holders and such other holders.

(d) If any Holder or other holder disapproves of the terms of any such underwriting, he or she may elect to withdraw therefrom by written notice to the Company and the managing underwriter. Any securities excluded or withdrawn from such underwriting shall be withdrawn from such registration, and shall continue to be subject to the terms of this Agreement, including Section 6 hereof. Furthermore,

(1) Following the date hereof, the Company shall not grant to any shareholder any rights superior to those granted to the Preferred Stockholders pursuant to this Section 5.1 without the prior consent of more than Fifty-One Percent (51%) of (A) the then-outstanding shares of Preferred Stock (on an as-converted basis) and Agent's Shares plus (B) if some or all of the shares of Preferred Stock have been converted into Common Stock, then the Conversion Stock issued pursuant to such conversion.

(2) Right to Terminate Registration. The Company shall have the right to terminate or withdraw any registration initiated by it under this Section 5.1 prior to the effectiveness of such registration whether or not any Holder has elected to include securities in such registration.

5.2 Expenses of Registration. Registration Expenses incurred in connection with all registrations pursuant to Section 5.1 shall be borne by the Company. Selling Expenses shall be borne by the selling shareholders incurring such expenses.

5.3 Registration Procedures. In the case of each registration, qualification or compliance effected by the Company pursuant to this Agreement, the Company will keep each Holder participating therein advised in writing as to the initiation of each registration, qualification and compliance and as to the completion thereof. At its expense, the Company will:

(a) Prepare and file with the Commission a registration statement with respect to such securities and use its best efforts to cause such registration statement to become and remain effective for at least ninety (90) days or until the distribution described in the registration statement has been completed, whichever first occurs; provided, however, that such 90-day period shall be extended for a period of time equal to the period the Holder refrains from selling any securities included in such registration at the request of an underwriter of Common Stock (or other securities) of the Company.

(b) Prepare and file with the Commission such amendments and supplements to such registration statement and the prospectus used in connection with such registration statement as may be necessary to comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such registration statement.

(c) Furnish to the Holders participating in such registration and to the underwriters of the securities being registered such reasonable number of copies of the registration statement, preliminary prospectus, final prospectus and such other documents (including amendments or supplements thereto) as such Holders or underwriters may reasonably request in order to facilitate the public offering of such securities.

(d) Use its best efforts to register and qualify the securities covered by such registration statement under such other securities or Blue Sky laws of such jurisdictions as shall be reasonably requested by the Holders; provided that the Company shall not be required in connection therewith or as a condition thereto to qualify to do business or to file a general consent to service of process in any such states or jurisdiction, unless the Company is already subject to service in such jurisdiction. Furthermore,

(1) In the event of any underwritten public offering, enter into and perform its obligations under an underwriting agreement, in usual and customary form, with the managing underwriter of such offering. Each Holder participating in such underwriting shall also enter into and perform its obligations under such an agreement.

(2) Notify each Holder of Registrable Securities covered by such registration statement at any time when a prospectus relating thereto is required to be delivered under the Securities Act of the happening of any event as a result of which the prospectus included in such registration statement, as then in effect, includes an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing and as promptly as practicable amend or supplement the prospectus to correct such misstatement or omission.

(3) Cause all such Registrable Securities registered pursuant hereunder to be listed on each securities exchange on which similar securities issued by the Company are then listed.

(4) Provide a transfer agent and registrar for all Registrable Securities registered pursuant hereunder and a CUSIP number for all such Registrable Securities, in each case not later than the effective date of such registration.

5.4 Indemnification.

(a) The Company will indemnify each Holder, each of such Holder's officers, directors, members, partners, legal counsel and agent, and each person controlling such Holder within the meaning of Section 15 of the Securities Act, with respect to which registration, qualification or compliance has been effected pursuant to this Agreement, and each underwriter, if any, and each person who controls any underwriter within the meaning of Section 15 of the Securities Act, against all expenses, claims, losses, damages or liabilities (or actions in respect thereof), including any of the foregoing incurred in settlement of any litigation, commenced or threatened, arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained in any registration statement, prospectus, offering circular or other document, or any amendment or supplement thereto, incident to any such registration, qualification or compliance, or based on any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading or any violation by the Company of the Securities Act, the Securities Exchange Act of 1934 (the "1934 Act"), state securities law or any rule or regulation promulgated under such laws applicable to the Company in connection with any

such registration, qualification or compliance, and the Company will reimburse each such Holder, each of such Holder's officers and directors, and members, partners, legal counsel, agents and each person controlling such Holder, each such underwriter and each person who controls any such underwriter, for any legal and any other expenses reasonably incurred, as such expenses are incurred, in connection with investigating, preparing or defending of any such claim, loss, damage, liability or action; provided, however, that the Company will not be liable in any such case to the extent that any such claim, loss, damage, liability or expense arises out of or is based on any untrue statement or omission or alleged untrue statement or omission, made in reliance upon and in conformity with written information furnished to the Company by an instrument duly executed by such Holder, controlling person or underwriter and stated to be specifically for use therein; provided, further, that the indemnity contained in this Subsection 5.4(a) shall not apply to amounts paid in settlement of any such claim, loss, damage, liability, or action if settlement is effected without the consent of the Company (which consent shall not unreasonably be withheld); and provided, further, that this indemnity agreement with respect to a preliminary prospectus shall not inure to the benefit of any Holder from whom the person asserting any such losses, liabilities, claims, damages or expenses purchased Registrable Securities, or any person controlling such Holder, if a copy of the prospectus (as amended or supplemented at the time of sale) was not sent or given by or on behalf of the Holder to such person and if the prospectus (as so amended or supplemented) would have corrected the defect giving rise to such loss, liability, claim, damage or expense.

(b) Each Holder severally, and not jointly will, if Registrable Securities held by such Holder are included in the securities as to which such registration, qualification or compliance is being effected, indemnify the Company, each of its directors and officers, each underwriter, if any, of the Company's securities covered by such a registration statement, each person who controls the Company or such underwriter within the meaning of Section 15 of the Securities Act, and each other such Holder, each of such Holder's officers and directors and each person controlling such Holder within the meaning of Section 15 of the Securities Act, against all claims, losses, damages and liabilities (or actions in respect thereof) arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained in any such registration statement, prospectus, offering circular or other document, or any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse the Company, such Holders, such directors, officers, persons, underwriters or control persons for any legal or any other expenses reasonably incurred, as such expenses are incurred, in connection with investigating or defending any such claim, loss, damage, liability or action, in each case to the extent, but only to the extent, that such untrue statement (or alleged untrue statement) or omission (or alleged omission) is made in such registration statement, prospectus, offering circular or other document in reliance upon and in conformity with written information furnished to the Company by an instrument duly executed by such Holder and stated to be specifically for use therein. Notwithstanding the foregoing, the liability of each Holder under this Subsection 5.4(b), together with any liability under Subsection 5.4(d), shall be limited in an amount equal to the net proceeds received from the sale of the shares sold by such Holder, and the indemnity contained in this Subsection 5.4(b) shall not apply to amounts paid in settlement of any such claim, loss, damage, liability or action if settlement is effected without the consent of such Holder (which consent shall not be unreasonably withheld).

(c) Each party entitled to indemnification under this Subsection 5.4 (the "Indemnified Party") shall give notice to the party required to provide indemnification (the "Indemnifying Party") promptly after such Indemnified Party has actual knowledge of any claim as to which indemnity may be sought, and shall permit the Indemnifying Party to assume the defense of any such claim or any litigation resulting therefrom, provided that counsel for the Indemnifying Party, who shall conduct the defense of such claim or litigation, shall be approved by the Indemnified Party (whose

approval shall not unreasonably be withheld), and the Indemnified Party may participate in such defense at such party's expense, and provided further that the failure of any Indemnified Party to give notice as provided herein shall not relieve the Indemnifying Party of its obligations under this Agreement unless the failure to give such notice is materially prejudicial to an Indemnifying Party's ability to defend such action and provided further, that the Indemnifying Party shall not assume the defense for matters as to which there is a conflict of interest or separate and different defenses.

(d) If the indemnification provided for in this Subsection 5.4 is held by a court of competent jurisdiction to be unavailable to an Indemnified Party with respect to any loss, liability, claim, damage, or expense referred to therein, then the Indemnifying Party, in lieu of indemnifying such Indemnified Party hereunder, shall to the extent permitted by applicable law contribute to the amount paid or payable by such Indemnified Party as a result of such loss, liability, claim, damage, or expense in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party on the one hand and of the Indemnified Party on the other in connection with the statements or omissions that resulted in such loss, liability, claim, damage, or expense as well as any other relevant equitable considerations. The relative fault of the Indemnifying Party and of the Indemnified Party shall be determined by a court of law by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission to state a material fact relates to the information supplied by the Indemnifying Party or by the Indemnified Party and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. Notwithstanding the foregoing, the amount to be contributed by any Holder under this Subsection 5.4(d), together with any liability under Subsection 5.4(b), shall be limited to an amount equal to the net proceeds received from the sale of the shares sold by such Holder.

(e) Notwithstanding the foregoing, to the extent that the provisions on indemnification and contribution contained in the underwriting agreement entered into in connection with the underwritten public offering are in conflict with the foregoing provisions, the provisions in the underwriting agreement shall control.

(f) The obligations of the Company and the Holders under this Section 5.5 shall survive completion of any offering of Registrable Securities in a registration statement and the termination of this Agreement. No Indemnifying Party shall, except with the consent of each Indemnified Party, consent to entry of any judgment or enter into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to each Indemnified Party of a release from all liability in respect to such claim or litigation. No person guilty of fraudulent misrepresentations (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who is not guilty of such fraudulent misrepresentation.

5.5 Information by Holder. The Holder or Holders of Registrable Securities included in any registration shall furnish to the Company such information regarding such Holder or Holders, the Registrable Securities held by them and the distribution proposed by such Holder or Holders as the Company may request in writing and as shall be required in connection with any registration, qualification or compliance referred to in this Agreement.

5.6 Rule 144 Reporting. With a view to making available the benefits of certain rules and regulations of the Commission which may at any time permit the sale of the Restricted Securities to the public without registration, the Company agrees to use all reasonable efforts to:

(a) Make and keep public information available, as those terms are understood and defined in Rule 144 under the Securities Act, at all times after the effective date that the Company becomes subject to the reporting requirements of the Securities Act or the 1934 Act;

(b) File with the Commission in a timely manner all reports and other documents required of the Company under the Securities Act and the 1934 Act (at any time after it has become subject to such reporting requirements); and

(c) So long as the Holder owns any Restricted Securities to furnish to the Holder forthwith upon request a written statement by the Company as to its compliance with the reporting requirements of said Rule 144, and of the Securities Act and the 1934 Act, a copy of the most recent annual or quarterly report of the Company, and such other reports and documents of the Company and other information in the possession of or reasonably obtainable by the Company as the Holder may reasonably request in availing itself of any rule or regulation of the Commission allowing the Holder to sell any such securities without registration.

5.7 Transfer of Registration Rights. The rights to cause the Company to register securities granted to the Holders under Section 5.1 may be assigned to a transferee or assignee in connection with (a) any transfer or assignment of Fifty Thousand (50,000) (as adjusted for stock splits, stock dividends, recapitalizations and the like) or more shares of Registrable Securities by the Holder to one or more persons in a single transaction or series of related transactions, provided that (i) the Company is given notice thereof and the transferee covenants to be bound by the provisions of this Agreement and (ii) such transfer may otherwise be affected in accordance with applicable securities laws or (b) any transfer or assignment of Registrable Securities by the Holder to partners, members or affiliates of such Holder.

5.8 Subsequent Registration Rights. From and after the date of this Agreement, the Company shall not grant any registration rights to subsequent purchasers of the Company's equity securities that are, in the good faith judgment of the Company's Board of Directors, superior to the registration rights granted to the Preferred Stockholders hereunder without the prior written consent of the holders of at least Fifty One Percent (51%) of the Registrable Securities.

6. Amendment.

Any provision of this Agreement may be amended or the observance thereof may be waived (either generally or in a particular instance and either retroactively or prospectively), only with the written consent of the Company and the holders of not less than a majority of the Registrable Securities then outstanding. Any amendment or waiver effected in accordance with this Section 6 shall be binding upon each Preferred Stockholder and each Holder of Registrable Securities at the time outstanding (including securities into which such securities are convertible), each future holder of all such securities, and the Company.

7. Governing Law.

This Agreement and the legal relations between the parties arising hereunder shall be governed by and interpreted in accordance with the laws of the State of California, without respect to rules concerning the conflict of laws which would otherwise require application of the substantive law of another jurisdiction. The parties hereto agree to submit to the jurisdiction of the federal and state courts of the State of California matters with respect to the breach or interpretation of this Agreement or the enforcement of any and all rights, duties, liabilities, obligations, powers, and other relations between the parties arising under this Agreement.

8. Entire Agreement.

This Agreement, together with all Exhibits hereto, constitute the full and entire understanding and agreement between the parties regarding the matters set forth herein. Except as otherwise expressly provided herein, the provisions hereof shall inure to the benefit of, and be binding upon the successors, assigns, heirs, executors and administrators of the parties hereto.

10. Counterparts.
