SECTION 8 REGISTRATION RIGHTS The Purchasers shall have the registration rights set forth in the Registration Rights Agreement attached hereto as Exhibit E.

The Company hereby grants to each Purchaser the right of first refusal to purchase all or any part of such Purchaser's pro rata share of New Securities (as defined in this Section 9.1) which the Company may, from time to time, propose to sell and issue. A pro rata share, for purposes of this right of first refusal, is the ratio that the sum of the number of shares of Common Stock then held by such Purchaser and the number of shares of Common Stock issuable upon conversion of the Preferred Stock then held by such Purchaser bears to the sum of (i) the total number of shares of Common Stock then outstanding plus (ii) the number of shares of Common Stock issuable upon conversion of the then outstanding Preferred Stock, plus (iii) the number of shares issuable upon exercise of outstanding options and warrants plus (iv) any shares reserved for future issuance pursuant to plans approved by the Company's Board of Directors. (a) Except as set forth below, "New Securities" shall mean any shares of capital stock of the Company including Common Stock and Preferred Stock, whether now authorized or not, and rights, options or warrants to purchase said shares of Common Stock or Preferred, and securities of any type whatsoever that are, or may become, convertible into said shares of Common Stock or Preferred. Notwithstanding the foregoing, "New Securities" does not include (i) the Shares purchased under this Agreement, including Common Stock issuable upon conversion of the Preferred, (ii) securities offered to the public generally pursuant to a registration statement or pursuant to Regulation A under the Securities Act, (iii) securities issued pursuant to the acquisition of another corporation by the Company by merger, purchase of -13- 18 substantially all of the assets or other reorganization whereby the Company or its shareholders own not less than fifty-one percent (51%) of the voting power of the surviving or successor corporation, (iv) shares of the Company's Common Stock or related options convertible into such Common Stock issued to employees, officers and directors of, and consultants, customers, licensors, and vendors to, the Company, pursuant to any arrangement approved by the Board of Directors of the Company, (v) stock issued pursuant to any rights or agreements including without limitation convertible securities, options and warrants, provided that the rights of first refusal established by this Section 9.1 apply with respect to the initial sale or grant by the Company of such rights or agreements, (vi) stock issued in connection with any stock split, stock dividend or recapitalization by the Company. (b) In the event the Company proposes to undertake an issuance of New Securities, it shall give each Purchaser notice of its intention, describing the type of New Securities, and the price and terms upon which the Company proposes to issue the same. Each Purchaser shall have twenty (20) days from the date of such notice to agree to purchase up to their respective pro rata shares of such New Securities for the price and upon the terms specified in the notice by giving written notice to the Company and stating therein the quantity of New Securities to be purchased. (c) In the event a Purchaser fails to exercise the right of first refusal within said twenty (20) day period, the Company shall have one hundred (100) days thereafter to enter into an agreement and sell the New Securities not elected to be purchased by Purchasers at the price and upon the terms no more favorable to the purchasers of such securities than specified in the Company's notice. In the event the Company has not entered into an agreement and closed the sale of the New Securities within said one hundred (100) day period, the Company shall not thereafter issue or sell any New Securities, without first offering such securities in the manner provided above. (d) The right of first refusal granted under this Agreement shall expire upon the first to occur of the following: (i) upon the closing of a firm commitment underwritten public offering pursuant to an effective registation statement under the Securities Act covering the offer and sale of Common Stock of which the aggregate gross proceeds attributable to sales for the account of the Company exceed $10,000,000 at a per share issuance price of $5.00 per share; or (ii) as to a Purchaser if such Purchaser no longer holds 400,000 shares of Preferred and/or Common Stock issued upon conversion of the Preferred (appropriately adjusted for Recapitalizations). -14- 19 (e) The right of first refusal hereunder is not assignable except by each of such Purchasers to any wholly-owned subsidiary or constituent partner who acquires at least 400,000 shares (appropriately adjusted for Recapitalizations).

Any waiver, permit, consent or approval of any kind or character on the part of any holder of any breach or default under this Agreement, or any waiver on the part of any holder of any provisions or conditions of this agreement, must be in writing and shall be effective only to the extent specifically set forth in such writing.

Brownell - ----------------------------- Robert D. Brownell, Assistant Secretary 28 EXHIBIT A RESTATED CERTIFICATE OF INCORPORATION OF SPECTRX, INC. I. The name of this Corporation is SpectRx, Inc. (the "Corporation"). II. The address of the Corporation's registered office in the State of Delaware is Corporation Trust Center, 1209 Orange Street, in the City of Wilmington, County of New Castle, Zip Code 19801. The name of its registered agent at such address is The Corporation Trust Company. III. The purpose of the Corporation is to engage in any lawful act or activity for which corporations may be organized under the General Corporation Law of Delaware. IV. The Corporation is authorized to issue two classes of capital stock: Preferred Stock, $0.001 par value per share, and Common Stock, $0.001 par value per share. The total number of shares of Preferred Stock which the Corporation shall have the authority to issue is 4,000,000 of which 2,000,000 shares shall be designated Series A Preferred Stock ("Series A Preferred Stock") and 2,000,000 shares shall be designated Series A1 Preferred Stock ("Series A1 Preferred Stock"). The total number of shares of Common Stock which the Corporation shall have the authority to issue is 10,000,000. The Series A Preferred Stock and Series A1 Preferred Stock are herein collectively referred to as the "Preferred Stock." V. The rights, preferences, privileges and restrictions granted to or imposed upon the Common Stock and the Preferred Stock are as follows: 1. Dividends. The holders of Series A Preferred Stock and Series A1 Preferred Stock shall be entitled, when and if declared by the board of directors of the Corporation, to dividends out 29 of assets of the Corporation legally available therefor at the rate of $0.10 and $0.10 per share, per annum, respectively. Dividends on the Preferred Stock shall be payable in preference and prior to any payment of any dividend on the Common Stock of the Corporation. Thereafter, the holders of Common Stock shall be entitled, when and if declared by the board of directors of the Corporation, to dividends out of assets of the Corporation legally available therefor. Notwithstanding anything set forth in this paragraph 1, no dividends shall be payable on any shares of Common Stock issued with respect to shares of Series A1 Preferred Stock issued pursuant to paragraph 4(e)(ii). The right to dividends on shares of Common Stock and Preferred Stock shall not be cumulative, and no right shall accrue to holders of Common Stock or Preferred Stock by reason of the fact that dividends on said shares are not declared in any prior period. 2. Liquidation Preference. (a) Preference. In the event of any liquidation, dissolution or winding up of the Corporation, either voluntarily or involuntarily, the holders of Series A Preferred Stock and Series A1 Preferred Stock shall be entitled to receive, prior and in preference to any distribution of any of the assets or surplus funds of the Corporation to the holders of Common Stock of the Corporation, an amount equal to $1.00 and $1.00 per share, respectively, plus any declared but unpaid dividends. If upon such liquidation, dissolution or winding up of the Corporation, the assets of the Corporation are insufficient to provide for the cash payment described above to the holders of Preferred Stock, such assets as are available shall be paid to the holders of Preferred Stock in proportion to the full preferential amount each such holder is otherwise entitled to receive. After the payment or setting apart of payment to the holders of Preferred Stock of the preferential amounts so payable to them, the holders of Common Stock shall be entitled to receive any remaining assets of the Corporation on a pro rata basis, based upon the number of shares held. (b) Reorganization or Merger. A reorganization or merger of the Corporation with or into any other corporation or corporations, or a sale of all or substantially all of the assets of the Corporation shall be deemed to be a liquidation within the meaning of this paragraph 2; provided that the holders of Preferred Stock and Common Stock shall be paid in cash or in securities received or in a combination thereof (which combination shall be in the same proportions as the consideration received in the transaction). Any securities to be delivered to the holders of the Preferred Stock and Common Stock upon a merger, reorganization or sale of substantially all of the assets of the Corporation shall be valued as follows: (i) If traded on a securities exchange, the value shall be deemed to be the average of the closing prices of the securities on such exchange over the 30-day period ending three (3) business days prior to the closing; (ii) If actively traded over-the-counter, the value shall be deemed to be the average of the closing bid prices over the 30-day period ending three (3) business days prior to the closing; and -2- 30 (iii) If there is no active public market, the value shall be the fair market value thereof, as mutually determined by the Corporation and the holders of not less than a majority of the outstanding shares of Preferred Stock, provided that if the Corporation and the holders of a majority of the outstanding shares of Preferred Stock are unable to reach agreement, then by independent appraisal by an investment banker hired and paid by the Corporation, but acceptable to the holders of a majority of the outstanding shares of Preferred Stock. (c) Noncash Distributions. If any of the assets of the Corporation are to be distributed other than in cash under this paragraph 2 or for any purpose, then the board of directors of the Corporation shall promptly engage independent competent appraisers to determine the value of the assets to be distributed to the holders of Preferred Stock or Common Stock. The Corporation shall, upon receipt of such appraiser's valuation, give prompt written notice to each holder of shares of Preferred Stock or Common Stock of the appraiser's valuation. 3. Voting Rights. (a) The holder of each share of Preferred Stock shall be entitled to the number of votes equal to the largest number of full shares of Common Stock into which each share of Preferred Stock could be converted on the record date for the vote or written consent of stockholders and, except as otherwise required by law, shall have voting rights and powers equal to the voting rights and powers of the Common Stock. The holder of each share of Preferred Stock shall be entitled to notice of any stockholders' meeting in accordance with the bylaws of the Corporation and shall vote with holders of the Common Stock upon all other matters submitted to a vote of stockholders, except those matters required to be submitted to a class or series vote pursuant to paragraph 5 or by law. Fractional votes shall not, however, be permitted and any fractional voting rights resulting from the above formula (after aggregating all shares of Common Stock into which shares of Preferred Stock held by each holder could be converted) shall be rounded to the nearest whole number (with one-half rounded upward to one). (b) Notwithstanding the foregoing, as long as more than 800,000 shares of Preferred Stock are outstanding, the holders of Preferred Stock, voting as a class, shall have the right to elect two members of the Corporation's board of directors. The holders of Common Stock, voting as a single class, shall have the right to elect all other members of the Corporation's board of directors. Notwithstanding any Bylaw provisions to the contrary, the stockholders entitled to elect a particular director shall be entitled to remove such director or to fill a vacancy in the seat formerly held by such a director, all in accordance with the applicable provisions provided in the General Corporation Law of the State of Delaware. 4. Conversion. The holders of the Preferred Stock shall have conversion rights as follows (the "Conversion Rights"): (a) Right to Convert. Each share of Preferred Stock shall be convertible without the payment of any additional consideration by the holder thereof and, at the option of the holder -3- 31 thereof, at any time after the date of issuance of such share at the office of the Corporation or any transfer agent for the Preferred Stock. Each share of each series of Preferred Stock shall be convertible into the number of fully paid and nonassessable shares of Common Stock which results from dividing the Conversion Price (as hereinafter defined) per share in effect for such series of Preferred Stock at the time of conversion into the per share Conversion Value (as hereinafter defined) of such series. Upon the filing of this Restated Certificate of Incorporation with the Delaware Secretary of State, the Conversion Price per share of Series A Preferred Stock shall be $1.00, and the per share Conversion Value of Series A Preferred Stock shall be $1.00, and the Conversion Price per share of Series A1 Preferred Stock shall be $1.00, and the per share Conversion Value of Series A1 Preferred Stock shall be $1.00. The Conversion Prices of Series A Preferred Stock and Series A1 Preferred Stock shall be subject to adjustments from time to time as provided below. The number of shares of Common Stock into which a share of a series of Preferred Stock is convertible is hereinafter referred to as the "Conversion Rate" of such series. (b) Automatic Conversion. Each share of Preferred Stock shall automatically be converted into shares of Common Stock at its then effective Conversion Rate immediately upon the closing of a firm commitment underwritten public offering pursuant to an effective registration statement under the Securities Act of 1933, as amended, covering the offer and sale of Common Stock of which the aggregate gross proceeds attributable to sales for the account of the Corporation exceed $10,000,000 at a per share issuance price of at least $5.00 per share. (c) Mechanics of Conversion. Before any holder of Preferred Stock shall be entitled to convert the same into shares of Common Stock, such holder shall surrender the certificate(s) therefor, duly endorsed, at the office of the Corporation or of any transfer agent for the Preferred Stock and shall give written notice to the Corporation at such office that the holder elects to convert the same (except that no such written notice of election to convert shall be necessary in the event of an automatic conversion pursuant to paragraph 4(b) hereof). The Corporation shall, as soon as practicable thereafter, issue and deliver at such office to such holder of Preferred Stock certificate(s) for the number of shares of Common Stock to which the holder shall be entitled as aforesaid. Such conversion shall be deemed to have been made immediately prior to the close of business on the date of such surrender of the shares of Preferred Stock to be converted (except that in the case of an automatic conversion pursuant to paragraph 4(b) hereof such conversion shall be deemed to have been made immediately prior to the closing of the offering referred to in paragraph 4(b)) and the person(s) entitled to receive the shares of Common Stock issuable upon such conversion shall be treated for all purposes as the record holder(s) of such shares of Common Stock on such date. (d) Fractional Shares. In lieu of any fractional shares to which the holder of Preferred Stock would otherwise be entitled, the Corporation shall pay cash equal to such fraction multiplied by the fair market value of one share of Common Stock as determined by the board of directors of the Corporation. Whether or not fractional shares of Common Stock are issuable upon such conversion shall be determined on the basis of the total number of shares of Preferred Stock of -4- 32 each holder at the time converting into Common Stock and the number of shares of Common Stock issuable upon such aggregate conversion. (e) Adjustment of Conversion Price. (i) Special Definitions.

(C) "Preferred Stock Pro Rata Share" shall mean the amount determined by multiplying the total number of shares of Common Stock (including securities exercisable for or convertible into Common Stock) offered for sale by the Corporation in a Financing to all parties by a fraction, (x) the numerator of which is the total number of shares of Common Stock (including securities convertible into Common Stock) held by such stockholder and (y) the denominator of which is the total number of shares of Common Stock (including securities convertible into Common Stock) then outstanding plus any shares reserved for issuance pursuant to plans approved by the board of directors of the Corporation. (D) "Series A Dilutive Issuance" shall mean an issuance of Common Stock (including securities exercisable for or convertible into Common Stock) in a Financing for a consideration per share less than the Conversion Price of the Series A Preferred Stock in effect on the date of and immediately prior to such issue. -5- 33 (E) "Participating Investor" shall mean any holder of Series A Preferred Stock that purchases at least its Preferred Stock Pro Rata Share of a Series A Dilutive Issuance.

(iv) If the number of shares of Common Stock outstanding at any time after the date hereof is increased by a stock dividend payable in shares of Common Stock or by a subdivision or split-up of shares of Common Stock, then, on the date such payment is made or such change is effective, the Conversion Price of a series of Preferred Stock shall be appropriately decreased so that the number of shares of Common Stock issuable on conversion of any shares of such series of Preferred Stock shall be increased in proportion to such increase of outstanding shares of Common Stock. -8- 36 (v) If the number of shares of Common Stock outstanding at any time after the date hereof is decreased by a combination of the outstanding shares of Common Stock, then, on the effective date of such combination, the Conversion Price of a series of Preferred Stock shall be appropriately increased so that the number of shares of Common Stock issuable on conversion of any shares of a series of Preferred Stock shall be decreased in proportion to such decrease in outstanding shares of Common Stock.

The provisions of this clause (vi) shall similarly apply to successive reorganizations, reclassifications, consolidations, mergers, sales or other dispositions.

Requested Registration. (a) Request for Registration. In case the Company shall receive from Initiating Holders a written request that the Company effect any registration, qualification or compliance with respect to at least 80% of the shares of Registrable Securities held by them (or any lesser number of shares of Registrable Securities having an expected aggregate offering price, net of underwriting discounts and commissions, greater than $7,500,000), the Company will: (i) promptly give written notice of the proposed registration, qualification or compliance to all other Holders; and (ii) as soon as practicable, use its best efforts to effect such registration, qualification or compliance (including, without limitation, appropriate qualification under applicable blue sky or other state securities laws and appropriate compliance with applicable regulations issued under the Act and any other governmental requirements or regulations) as may be so requested and as would permit or facilitate the sale and distribution of all or such portion of such Registrable Securities as are specified in such request, together with all or such portion of the Registrable Securities of any Holder or Holders joining in such request as are specified in a written request received by the Company within 20 days after receipt of such written notice from the Company. Provided, however, that the Company shall not be obligated to take any action to effect any such registration, qualification or compliance pursuant to this paragraph 2: (1) In any particular jurisdiction in which the Company would be required to execute a general consent to service of process in effecting such registration, qualification or 54 compliance unless the Company is already subject to service in such jurisdiction and except as may be required by the Act; (2) Prior to the earlier of (i) November 1, 1994 or (ii) six months after the effective date of the Company's first registered public offering of its stock; (3) During the period starting with the date sixty (60) days prior to the Company's estimated date of filing of, and ending on the date three (3) months immediately following the effective date of, any registration statement pertaining to securities of the Company (other than a registration of securities in a Rule 145 transaction or with respect to an employee benefit plan), provided that the Company is actively employing in good faith all reasonable efforts to cause such registration statement to become effective; (4) After the Company has effected two such registrations pursuant to this paragraph 2(a), and such registrations have been declared or ordered effective; or (5) If the Company shall furnish to such Holders a certificate signed by the President of the Company that in the good faith judgment of the Board of Directors it would be seriously detrimental to the Company or its shareholders for a registration statement to be filed at such time, then the Company's obligation to use its best efforts to register, qualify or comply under this paragraph 2 shall be deferred for a period not to exceed 90 days from the date of receipt of written request from the Initiating Holders, provided, however, that the Company may not make such certification more than once every calendar year. Subject to the foregoing clauses (1) through (5), the Company shall file a registration statement covering the Registrable Securities so requested to be registered as soon as practicable, after receipt of the request or requests of the Initiating Holders and in any event within one hundred eighty (180) days after receipt of such request. (b) Underwriting. In the event that a registration pursuant to this paragraph 2 is for a registered public offering involving an underwriting, the Company shall so advise the Holders as part of the notice given pursuant to paragraph 2(a)(i). In such event, the right of any Holder to such registration shall be conditioned upon such Holder's participation in the underwriting arrangements required by this paragraph 2, and the inclusion of such Holder's Registrable Securities in the underwriting to the extent requested shall be limited to the extent provided herein. The Company shall (together with all Holders proposing to distribute their securities through such underwriting) enter into an underwriting agreement in customary form with the managing underwriter selected for such underwriting by a majority in interest of the Initiating Holders, but subject to the Company's reasonable approval. Notwithstanding any other provision of this paragraph 2, if the managing underwriter advises the Initiating Holders in writing that marketing factors require a limitation of the number of shares to be underwritten, then the Company shall so advise all holders of Registrable Securities and the number of shares of Registrable Securities that may be included in the registration and 55 underwriting shall be allocated among all Holders thereof (except those Holders who have indicated to the Company their decision not to distribute any of their Registrable Securities through such underwriting) in proportion, as nearly as practicable, to the respective amounts of Registrable Securities held by such Holders at the time of filing the registration statement, provided, however, that the number of shares of Registrable Securities to be included in such underwriting shall not be reduced unless all other securities are first entirely excluded from the underwriting. No Registrable Securities excluded from the underwriting by reason of the underwriter's marketing limitation shall be included in such registration. To facilitate the allocation of shares in accordance with the above provisions, the Company or the underwriters may round the number of shares allocated to any Holder to the nearest 100 shares. If any Holder of Registrable Securities disapproves of the terms of the underwriting, such person may elect to withdraw therefrom by written notice to the Company, the managing underwriter and the Initiating Holders. The Registrable Securities and/or other securities so withdrawn shall also be withdrawn from registration, and such Registrable Securities shall not be transferred in a public distribution prior to 90 days after the effective date of such registration, or such other shorter period of time as the underwriters may require. 3. Company Registration. (a) Notice of Registration. If at any time or from time to time the Company shall determine to register any of its securities, either for its own account or the account of a security holder or holders, other than (i) in connection with the Company's initial public offering, (ii) a registration relating solely to employee benefit plans, or (iii) a registration relating solely to a Commission Rule 145 transaction, the Company will: (i) promptly give to each Holder written notice thereof; and (ii) 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 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 paragraph 3(a)(i). In such event the right of any Holder to registration pursuant to this paragraph 3 shall be conditioned upon such Holder's participation in such underwriting and the inclusion of Registrable Securities in the underwriting to the extent provided herein. 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. 56 Notwithstanding any other provision of this paragraph 3, if the managing underwriter determines that marketing factors require a limitation of the number of shares to be underwritten, the managing underwriter may limit the Registrable Securities or other securities to be included in such registration or exclude them entirely. The Company shall so advise all Holders and other holders distributing their securities through such underwriting and the number of shares of Registrable Securities and other securities that may be included in the registration and underwriting shall be allocated among the holders thereof in proportion, as nearly as practicable, to the respective amounts of Registrable Securities and other securities held by such holders at the time of filing the registration statement. To facilitate the allocation of shares in accordance with the above provisions, the Company may round the number of shares allocated to any Holder or holder to the nearest 100 shares. If any Holder or holder disapproves of the terms of any such underwriting, he 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 not be transferred in a public distribution prior to 90 days after the effective date of the registration statement relating thereto, or such other shorter period of time as the underwriters may require. (c) Right to Terminate Registration. The Company shall have the right to terminate or withdraw any registration initiated by it under this paragraph 3 prior to the effectiveness of such registration whether or not any Holder has elected to include securities in such registration. 4. Registration on Form S-3. (a) If any Holder or Holders request that the Company file a registration statement on Form S-3 (or any successor form to Form S-3) for a public offering of shares of the Registrable Securities the reasonably anticipated aggregate price to the public of which, net of underwriting discounts and commissions, would exceed $500,000, and the Company is a registrant entitled to use Form S-3 to register the Registrable Securities for such an offering, the Company shall use its best efforts to cause such Registrable Securities to be registered for the offering on such form and to cause such Registrable Securities to be qualified in such jurisdictions as the Holder or Holders may reasonably request; provided, however, that the Company shall not be required to effect more than one registration pursuant to this paragraph 4 in any calendar year. The substantive provisions of paragraph 3(b) shall be applicable to each registration under this paragraph 4. (b) Notwithstanding the foregoing, the Company shall not be obligated to take any action pursuant to this paragraph 4: (i) in any particular jurisdiction in which the Company would be required to execute a general consent to service of process in effecting such registration, qualification or compliance unless the Company is already subject to service in such jurisdiction and except as may be required by the Act; (ii) if the Company, within ten (10) days of the receipt of the request of the initiating Holders, gives notice of its bona fide intention to effect the filing of a registration statement with the Commission within ninety (90) days of receipt of such request (other than with respect to a registration statement relating to a Rule 145 transaction, an offering solely to employees or any other registration which is not appropriate for the registration of Registrable Securities); (iii) during the period starting with 57 the date sixty (60) days prior to the Company's estimated date of filing of, and ending on the date six (6) months immediately following, the effective date of any registration statement pertaining to securities of the Company (other than a registration of securities in a Rule 145 transaction or with respect to an employee benefit plan), provided that the Company is actively employing in good faith all reasonable efforts to cause such registration statement to become effective; or (iv) if the Company shall furnish to such Holder a certificate signed by the President of the Company stating that in the good faith judgment of the Board of Directors it would be seriously detrimental to the Company or its shareholders for registration statements to be filed at such time, then the Company's obligation to use its best efforts to file a registration statement shall be deferred for a period not to exceed 90 days from the receipt of the request to file such registration by such Holder provided that the Company may not make such certification more than once every calendar year. 5. Expenses of Registration. All Registration Expenses (exclusive of underwriting discounts and commissions or fees of special counsel for a selling Holder) incurred in connection with (i) two registrations pursuant to paragraph 2 and (ii) all registrations pursuant to paragraphs 3 and 4 shall be borne by the Company. 6. 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 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 one hundred and twenty (120) days or until the distribution described in the Registration Statement has been completed; (b) Prepare and file with the SEC 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 1933 Act with respect to the disposition of all securities covered by such registration statement. (c) Furnish to the Holders such numbers of copies of a prospectus, including a preliminary prospectus, in conformity with the requirements of the Act, and such other documents as they may reasonably request in order to facilitate the disposition of Registrable Securities owned by them. (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 jurisdictions. 58 (e) 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. (f) 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 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. (g) Furnish, at the request of any Holder requesting registration of Registrable Securities pursuant to this Agreement, on the date that such Registrable Securities are delivered to the underwriters for sale in connection with a registration pursuant to this Agreement, (i) an opinion, dated such date, of the counsel representing the Company for the purposes of such registration, in form and substance as is customarily given to underwriters in an underwritten public offering, addressed to the underwriters, if any, and to the Holders requesting registration of Registrable Securities and (ii) a letter dated such date, from the independent accountants of the Company, in form and substance as is customarily given by independent accountants to underwriters in an underwritten public offering, addressed to the underwriters, if any, and to the Holders requesting registration of Registrable Securities. 7. Indemnification. (a) The Company will indemnify each Holder, each of its officers and directors and partners, and each person controlling such Holder within the meaning of Section 15 of the 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 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, in light of the circumstances in which they were made, not misleading, or any violation by the Company of any federal, state or common law rule or regulation applicable to the Company in connection with any such registration, qualification or compliance, and the Company will reimburse each such Holder, each of its officers and directors, 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 in connection with investigating, preparing or defending any such claim, loss, damage, liability or action, provided 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 59 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. (b) Each Holder 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 Act, and each other such Holder, each of its officers and directors and each person controlling such Holder within the meaning of Section 15 of the 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 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 (b) shall be limited in an amount equal to the public offering price of the shares sold by such Holder, unless such liability arises out of or is based on willful conduct by such Holder. (c) Each party entitled to indemnification under this paragraph 7 (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, provided, however, that the Indemnifying Party shall bear the expense of independent counsel for the Indemnified Party if the Indemnified Party reasonably determines that representation of both parties by the same counsel would be inappropriate due to actual or potential conflicts of interest, 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. No Indemnifying Party, in the defense of any such claim or litigation, 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 such Indemnified Party of a release from all liability in respect to such claim or litigation. 60 8. 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. 9. 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, after such time as a public market exists for the Common Stock of the Company, the Company agrees to use its best efforts to: (a) Make and keep public information available, as those terms are understood and defined in Rule 144 under the Act, at all times after the effective date that the Company becomes subject to the reporting requirements of the Act or the Securities Exchange Act of 1934, as amended. (b) Use its best efforts to file with the Commission in a timely manner all reports and other documents required of the Company under the Act and the Securities Exchange Act of 1934, as amended (at any time after it has become subject to such reporting requirements); (c) So long as a Purchaser owns any Restricted Securities to furnish to the Purchaser forthwith upon request a written statement by the Company as to its compliance with the reporting requirements of said Rule 144 (at any time after 90 days after the effective date of the first registration statement filed by the Company for an offering of its securities to the general public), and of the Act and the Securities Exchange Act of 1934 (at any time after it has become subject to such reporting requirements), 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 a Purchaser may reasonably request in availing itself of any rule or regulation of the Commission allowing a Purchaser to sell any such securities without registration. 10. Transfer of Registration Rights. The rights to cause the Company to register securities granted Purchasers under paragraphs 2, 3 and 4 may be assigned to a transferee or assignee in connection with any transfer or assignment of Registrable Securities by a Purchaser provided that: (i) such transfer may otherwise be effected in accordance with applicable securities laws, and (ii) such assignee or transferee acquires at least 400,000 Shares and/or the Conversion Stock into which the Shares are convertible. Notwithstanding the foregoing, the rights to cause the Company to register securities may be assigned, in connection with a distribution by such Purchaser, to any parent or subsidiary company or to any partner, former partner, or the estate of any such partner without compliance with item (ii) above, provided written notice thereof is promptly given to the Company. 11. Standoff Agreement. Each Holder agrees, in connection with the Company's initial public offering of the Company's securities that, upon request of the Company or the underwriters managing any underwritten offering of the Company's securities, not to sell, make any short sale of, loan, grant any option for the purchase of, or otherwise dispose of any Common Stock of the Company (other than those 61 included in the registration) without the prior written consent of the Company or such underwriters, as the case may be, for such period of time (not to exceed one hundred eighty (180) days) from the effective date of such registration as may be requested by the underwriters, provided that the officers and directors of the Company enter into similar agreements. 12. Termination of Registration Rights. All rights of the Holders under this Agreement shall terminate four (4) years from the date of the Company's initial public offering. 13. Amendment of Registration Rights. Any provision of the Agreement may be amended and 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 a majority of the Registrable Securities then outstanding. Any amendment or waiver effected in accordance with this paragraph shall be binding upon each holder of any Registrable Securities then outstanding, each future holder of all such Registrable Securities, and the Company. 14. Limitations on Subsequent Registration Rights. From and after the date of this Agreement, the Company shall not, without the prior written consent of the Holders of a majority of the outstanding Registrable Securities, enter into any agreement with any holder or prospective holder of any securities of the Company which would allow such holder or prospective holder (a) to include such securities in any registration filed under Section 2 hereof, unless under the terms of such agreement, such holder or prospective holder may include such securities in any such registration only to the extent that the inclusion of his securities will not reduce the amount of the Registrable Securities of the Holders which is included or (b) to make a demand registration which could result in such registration statement being declared effective prior to the earlier of either of the dates set forth in subsection 2.a.ii(2) or within one hundred twenty (120) days of the effective date of any registration effected pursuant to Section 2. 15. Entire Agreement. This Agreement constitutes the full and entire understanding and agreement among the parties with regard to the subject matter hereof.

NOW, THEREFORE, in consideration of the foregoing and the premises herein contained, Assignor hereby agrees with Lender as follows: 1. To secure the complete and timely satisfaction of all obligations of Assignor under the Note (the "Obligations"), Assignor hereby grants, assigns and conveys to Lender all of its rights, title and interest, resulting from the Assignment to: a) all right, title and interest in and to the technology, patents, software, designs, models, drawings, know-how, trademarks, trade names, and service marks (including the goodwill associated with the trademarks, trade names and service marks), trade secrets, copyrights, registrations and applications therefor, relating to non-invasive means of diagnosing disease through the use of flourescence spectroscopy, including, without limitation, any and all books, records, computer tapes or disks, flow diagrams, specifications sheets, source codes, and object codes relating to the foregoing and other physical manifestations of the foregoing; and b) all right, title, interest, powers, privileges and options in and to, and in accordance with, that certain license agreement dated May 7, 1991, by and between GEORGIA TECH RESEARCH CORPORATION and Seller, including without limitation, all proceeds thereof (such as, by way of example, license royalties and proceeds of infringement suits), the right to sue for past, present and future infringements, and 76 all rights corresponding thereto (collectively called the "Assets"). 2. Assignor agrees that, until all of the Obligations shall have been satisfied in full, it will not enter into any agreement (for example, a license agreement) which is inconsistent with Assignor's obligations under this Agreement, without Lender's prior written consent. 3. Unless and until there shall have occurred and be continuing a breach of the Obligations, Lender hereby grants to Assignor the exclusive, non-transferable right, license, and use of and to the Assets, provided, however, Assignor agrees not to sell, assign, or otherwise encumber its interest in, or grant any sublicense under the Assets, or any part thereof, without the prior written consent of Lender. 4. If any breach of the Obligations shall have occurred and be continuing, Assignor's rights, license, and use of and to the Assets set forth in Section 3, shall terminate forthwith, and the Lender shall have, in addition to all other rights and remedies given it by this Agreement, those allowed by law and the rights and remedies of a secured party under the Uniform Commercial Code as enacted in any jurisdiction in which the Assets may be located and, without limiting the generality of the foregoing, the Lender may immediately, without demand or performance and without other notice (except as set forth next below) or demand whatsoever to Assignor, all of which are hereby expressly waived, and without advertisement, sell at public or private sale or otherwise realize upon, in Atlanta, Georgia, or elsewhere, the whole or from time to time any part of the Assets, or any interest which the Assignor may have therein, and after deducting from the proceeds of sale or other disposition of the Assets all expenses (including all reasonable expenses for brokers' fees and legal services), shall apply the residue of such proceeds toward the satisfaction of the obligations. Any remainder of the proceeds after satisfaction in full of the Obligations shall be paid over to the Assignor. Notice of any sale or other disposition of the Assets shall be given to Assignor at least five (5) days before the time of nay intended public or private sale or other disposition of the Patents is to be made, which Assignor hereby agrees shall be reasonable notice of such sale or other disposition. At any such sale or other disposition, any holder of the Note or Lender may, to the extent permissable under applicable law, purchase the whole or any part of the Assets sold, free from any right of redemption on the part of Assignor, which right is hereby waived and released. 5. If any breach of the Obligations shall have occurred and be continuing, Assignor hereby authorizes and empowers Lender to make, constitute and appoint any officer or agent of Lender, as Lender may select in its exclusive discretion, as Assignor's true and lawful attorney-in-fact, with the power to endorse Assignor's 2 77 name on all applications, documents, papers and instruments necessary for Lender to use the Assets, or any part thereof, or to grant or issue any exclusive or non-exclusive license under the Assets, or any part thereof, to any third person, or necessary for Lender to assign, pledge, convey or otherwise transfer title in or dispose of the Assets, or any part thereof, to any third person. Assignor hereby ratifies all that such attorney shall lawfully do or cause to be done by virtue hereof. This power of attorney is coupled with an interest and shall be irrevocable for the life of this Agreement. 6. At such time as Assignor shall completely satisfy all of the Obligations, this Agreement shall terminate and Lender shall execute and deliver to Assignor all deeds, assignments and other instruments as may be necessary or proper to re-vest in Assignor full title to the Assets, subject to any disposition thereof which may have been made by Lender pursuant hereto. 7. No course of dealing between Assignor and Lender, nor any failure to exercise, nor any delay in exercising, on the part of Lender, any right, power or privilege hereunder or under the Note shall operate as a waiver thereof; nor shall any single or partial exercise of any right, power or privilege hereunder or thereunder preclude any other or further exercise thereof or the exercise of any other right, power or privilege. 8. All of Lender's rights and remedies with respect to the Assets, whether established hereby or by the Note, or by any other agreements or by law shall be cumulative and may be exercised singularly or concurrently. 9. The provisions of this Agreement are severable, and if any clause or provision shall be held invalid and unenforceable in whole or in part in any jurisdiction, then such invalidity or unenforceability shall affect only such clause or provision, or part thereof, in such jurisdiction, and shall not in any manner affect such clause or provision in any other jurisdiction, or any other clause or provision of this Agreement in any jurisdiction. 10. This Agreement is subject to modification only by a writing signed by the parties. 11. The benefits and burdens of this Agreement shall inure to the benefit of and be binding upon the respective successors and permitted assigns of the parties. 12. The validity and interpretation of this Agreement and the rights and obligations of the parties shall be governed by the laws of the State of Georgia. 3 78 WITNESS the execution hereof under seal as of the day and year first above written.

GEORGIA TECH RESEARCH CORPORATION By: --------------------------- Name: ------------------------- Title: ------------------------ By: --------------------------- Name: ------------------------- Title: ------------------------ 3 82 EXHIBIT G LEGAL OPINION 83 [WILSON SONSINI GOODRICH & ROSATI LETTERHEAD] February 5, 1993 To the Investors Listed in Exhibit A to the Spectrx, Inc. Series A Preferred Stock Purchase Agreement dated February 5, 1993 Gentlemen: Reference is made to the Series A Preferred Stock Purchase Agreement, dated as of February 5, 1993 (the "Agreement"), complete with all listed exhibits thereto (together, the "Agreements"), by and among Spectrx, Inc., a Delaware corporation (the "Company"), and the persons and entities listed in Exhibit A to the Agreement (the "Investors"), which provides for the issuance by the Company to the Investors of shares of Series A Preferred Stock of the Company. This opinion is rendered to you pursuant to Section 5.3 of the Agreement, and all terms used herein have the meanings defined for them in the Agreement unless otherwise defined herein. We have acted as counsel for the Company in connection with the negotiation of the Agreements and the issuance of the Series A Preferred Stock. As such counsel, we have made such legal and factual examinations and inquiries as we have deemed advisable or necessary for the purpose of rendering this opinion. In addition, we have examined originals or copies of such corporate records of the Company, certificates of public officials and such other documents which we consider necessary or advisable for the purpose of rendering this opinion. In such examination we have assumed the genuineness of all signatures on original documents, the authenticity and completeness of all documents submitted to us as originals, the conformity to original documents of all copies submitted to us and the due execution and delivery of all documents (except as to due execution and delivery by the Company) where due execution and delivery are a prerequisite to the effectiveness thereof. As used in this opinion, the expression "to our knowledge," "known to us" or similar language with reference to matters of fact 84 means that, after an examination of documents made available to us by the Company, and after inquiries of officers of the Company, but without any further independent factual investigation, we find no reason to believe that the opinions expressed herein are factually incorrect. Further, the expression "to our knowledge", "known to us" or similar language with reference to matters of fact refers to the current actual knowledge of the attorneys of this firm who have worked on matters for the Company. Except to the extent expressly set forth herein or as we otherwise believe to be necessary to our opinion, we have not undertaken any independent investigation to determine the existence or absence of any fact, and no inference as to our knowledge of the existence or absence of any fact should be drawn from our representation of the Company or the rendering of the opinion set forth below. For purposes of this opinion, we are assuming that you have all requisite power and authority, and have taken any and all necessary corporate or partnership action, to execute and deliver the Agreements, and we are assuming that the representations and warranties made by the Investors in the Agreement and pursuant thereto are true and correct. We are also assuming that the Investors have purchased the Shares for value, in good faith and without notice of any adverse claims. We are also assuming that the representations and warrants made by the Company in the Agreement and pursuant thereto are true and correct as to matters of fact. The opinions hereinafter expressed are subject to the following qualifications: (a) We express no opinion as to the effect of applicable bankruptcy, insolvency, reorganization, moratorium or other similar federal or state laws affecting the rights of creditors; (b) We express no opinion as to the effect of rules of law governing specific performance, injunctive relief or other equitable remedies (regardless of whether any such remedy is considered in a proceeding at law or in equity); (c) We express no opinion as to compliance with the anti-fraud provisions of applicable securities laws; (d) We express no opinion as to the enforceability of the indemnification provisions of paragraph 7 of the Registration Rights Agreement to the extent the provisions thereof may be subject to limitations of public policy and the effect of applicable statutes and judicial decisions; (e) We are members of the Bar of the State of California. We express no opinion as to any matter relating to the laws of any jurisdiction other than the federal laws of the United States of America and the laws of the State of California. To the extent this -2- 85 opinion addresses applicable securities laws of states other than the State of California, we have not retained nor relied on the opinion of counsel admitted to the bar of such states, but rather have relied on compilations of the securities laws of such states contained in reporting services presently available to us. Based upon and subject to the foregoing, and except as set forth in the Schedule of Exceptions to the Agreement, we are of the opinion that: 1. The Company is a corporation duly organized and validly existing under, and by virtue of, the laws of the State of Delaware and is in good standing under such laws. The Company has requisite corporate power to own and operate its properties and assets, and to carry on its business as presently conducted. The Company is not qualified to do business as a foreign corporation in any jurisdiction. The Company has no subsidiaries. 2. The Company has all requisite legal and corporate power to execute and deliver the Agreements and the Restated Articles of Incorporation, to sell and issue the Series A Preferred Stock thereunder, to issue the Common Stock issuable upon conversion of the Preferred Stock and to carry out and perform its obligations under the terms of the Agreements and the Restated Articles of Incorporation. 3. Immediately prior to the Closing, the authorized capital stock of the Company consists of 10,000,000 shares of Common Stock, 1,650,000 shares of which are issued and outstanding, and 4,000,000 shares of Preferred Stock, of which 2,000,000 shares are designated Series A Preferred Stock and 2,000,000 shares are designated Series A1 Preferred Stock. Immediately prior to Closing, none of the Preferred Stock is issued and outstanding. The Company has also reserved 500,000 shares of its Common Stock for issuance pursuant to its 1993 Incentive Stock Plan. All such issued and outstanding shares of Common Stock have been duly authorized and validly issued and are fully paid and nonassessable and free of any preemptive or similar rights contained in the Articles of Incorporation or Bylaws of the Company. The Common Stock issuable upon conversion of the Preferred Stock has been duly and validly reserved, and when issued in accordance with the Company's Articles of Incorporation will be validly issued, fully paid and nonassessable. The Series A Preferred Stock issued under the Agreement is validly issued, fully paid and nonassessable and free of any liens, encumbrances and pre-emptive or similar rights contained in the Articles of Incorporation or Bylaws of the Company; provided, however, that the Series A Preferred Stock (and the Common Stock issuable upon conversion of the Preferred) may be subject to restrictions on transfer under state and/or federal securities laws as set forth in the Agreement. To our knowledge, except for rights described in the Agreements and the Articles of Incorporation, there are no other options, warrants, -3- 86 conversion privileges or other rights presently outstanding to purchase or otherwise acquire any authorized but unissued shares of capital stock or other securities of the Company, or any other agreements to issue any such securities or rights. 4. All corporate action on the part of the Company, its directors and shareholders necessary for the authorization, execution and delivery of the Agreements and the Restated Articles of Incorporation by the Company, the authorization, sale, issuance and delivery of the Series A Preferred Stock (and the Common Stock issuable upon conversion of the Preferred Stock) and the performance of the Company's obligations under the Agreement and the Restated Articles of Incorporation have been taken. The Agreements and Restated Articles of Incorporation have been duly and validly executed and delivered by the Company and constitute valid and binding obligations of the Company. 5. The execution, delivery and performance of and compliance with the terms of the Agreements and the Restated Articles of Incorporation, and the issuance of the Series A Preferred Stock (and the Common Stock issuable upon conversion of the Preferred Stock), do not violate any provision of the Articles of Incorporation or Bylaws, or, to our knowledge, any provision of any applicable federal or state law, rule or regulation. To our knowledge, the execution, delivery and performance of and compliance with the Agreements and the Restated Articles of Incorporation, and the issuance of the Series A Preferred Stock (and the Common Stock issuable upon conversion of the Preferred) do not violate, or constitute a default under, any material contract, agreement, instrument, judgment or decree binding upon the Company. 6. To our knowledge, there are no actions, suits, proceedings or investigations pending against the Company or its properties before any court or governmental agency (nor, to our knowledge, has the Company received any written threat thereof), which, either in any case or in the aggregate, are likely to result in any material adverse change in the business or financial condition of the Company or any of its properties, or in any material impairment of the right or ability of the Company to carry on its business as now conducted, or which questions the validity of the Agreement or any action taken or to be taken by the Company in connection therewith. 7. No consent, approval or authorization of or designation, declaration or filing with any governmental authority on the part of the Company is required in connection with the valid execution and delivery of the Agreements and the Restated Articles of Incorporation, or the offer, sale or issuance of the Series A Preferred Stock (and the Common issuable upon conversion of the Preferred) or the consummation of any other transaction contemplated by the Agreements and the Restated Articles of Incorporation, except (a) filing of the Restated Articles of Incorporation in the Office -4- 87 of the Secretary of State of the State of Delaware, and (b) qualification (or taking such action as may be necessary to secure an exemption from qualification, if available) under applicable blue sky laws (but excluding jurisdictions outside of the United States) of the offer and sale of the Shares (and the Common issuable upon conversion thereof) and the modification of rights of shareholders contemplated by the Agreements. The filing referred to in clause (a) above has been accomplished and is effective. Our opinion herein is otherwise subject to the timely and proper completion of all filings and other actions contemplated herein where such filings and actions are to be undertaken on or after the date hereof. 8. Subject to the accuracy of the Investors' representations in Section 3 of the Agreement and their responses (if any) to the Company's inquiries, we are of the opinion that the offer, sale and issuance of the Shares in conformity with the terms of the Agreements constitute transactions exempt from the registration requirements of Section 5 of the Securities Act of 1933, as amended. This opinion is furnished to the Investors solely for their benefit in connection with the purchase of the Shares, and may not be relied upon by any other person or for any other purpose without our prior written consent. Very truly yours, /S/ WILSON SONSINI GOODRICH & ROSATI WILSON, SONSINI, GOODRICH & ROSATI Professional Corporation -5- 88 EXHIBIT H SAMUELS AGREEMENT 89 SPECTRX, INC. STOCK RESTRICTION AND CO-SALE AGREEMENT THIS AGREEMENT is made and entered into this ____ day of January, 1993 by and among Spectrx, Inc. (the "Company") a Delaware corporation, Mark Samuels (the "Major Shareholder"), and the investors set forth on the signature page of this agreement (the "Investors"). WHEREAS, the Investors have acquired or have expressed an interest in acquiring from the Company shares of its Series A Preferred Stock which are convertible into shares of Common Stock of the Company. WHEREAS, the Major Shareholder is presently the legal or beneficial owner of 434,143 shares of the outstanding Common Stock of the Company (the "Founding Shares"). WHEREAS, the Major Shareholder wishes to provide a further inducement to the Investors to purchase the Company's Series A Preferred Stock by offering, upon the terms and conditions set forth in this Agreement, the Company and the Investors a right to purchase and the Investors an opportunity to participate in subsequent sales of the Common Stock of the Company made by the Major Shareholder. IT IS THEREFORE AGREED AS FOLLOWS: 1. Option to Repurchase on Termination. 1.1 Repurchase Option. a. Terms of Option. In the event of the voluntary or involuntary termination of the Major Shareholder's employment with or services to the Company for any or no reason (including death or disability) the Company shall, upon the date of such termination (as reasonably fixed and determined by the Company) have an irrevocable, exclusive option (the "Repurchase Option") for a period of ninety (90) days from such date to repurchase all or any portion of the Founding Shares which have not been released from the Repurchase Option at such time at the Repurchase FMV (as defined below). The Repurchase Option shall be exercised by the Company by written notice to the Major Shareholder or his executor (with a copy to the Escrow Holder) and, at the Company's option, (i) by delivery to the Major Shareholder or his executor with such notice of a check in the amount of the Repurchase FMV for the Founding Shares being repurchased, or (ii) by cancellation by the Company of an amount of the Major Shareholder's indebtedness to the Company equal to the 90 Repurchase FMV for the Founding Shares being repurchased, or (iii) by a combination of (i) and (ii) so that the combined payment and cancellation of indebtedness equals such Repurchase FMV. Upon delivery of such notice and the payment of the Repurchase FMV in any of the ways described above, the Company shall become the legal and beneficial owner of the Founding Shares being repurchased and all rights and interests therein or relating thereto, and the Company shall have the right to retain and transfer to its own name the number of Founding Shares being repurchased by the Company. b. Repurchase FMV. The "Repurchase FMV" shall be the fair market value of the Founding Shares to be repurchased on the first day of the Repurchase Option, as determined in good faith by the Company's Board of Directors. 1.2 Release of Founding Shares From Repurchase Option. One-half (1/2) of the Founding Shares shall be released from the Company's Repurchase Option on the date of the closing of the Series A Preferred Stock Purchase Agreement of even date herewith by and among the Company and certain investors (the "Closing"), and an additional 1/36th of the Founding Shares not released from the Repurchase Option on the date of Closing shall be released at the end of each full month thereafter until all Founding Shares have been released; provided in each case that the Major Shareholder's employment or services have not been terminated prior to the date of any such release. 1.3 Escrow of Founding Shares. a. Assignment to Escrow. The Founding Shares shall be held by the Secretary of the Company or his designee as escrow holder ("Escrow Holder"), along with a stock assignment executed by the Major Shareholder in blank, until the expiration of the Company's option to repurchase such Founding Shares as set forth above. b. Escrow Instructions. The Escrow Holder is hereby directed to permit transfer of the Founding Shares only in accordance with this Agreement or instructions signed by both parties. In the event further instructions are desired by the Escrow Holder, he shall be entitled to rely upon directions executed by a majority of the Company's Board of Directors. The Escrow Holder shall have no liability for any act or omission hereunder while acting in good faith in the exercise of his own judgment. c. Transfer upon Exercise. If the Company or any assignee exercises its Repurchase Option, the Escrow Holder, upon receipt of written notice of such option exercise from the proposed transferee, shall take all steps necessary to accomplish such transfer. -2- 91 d. Delivery of Founding Shares. When the Repurchase Option has been exercised or expires unexercised or a portion of the Founding Shares has been released from the Repurchase Option, upon the Major Shareholder's request the Escrow Holder shall promptly cause a new certificate to be issued for such released Founding Shares and shall deliver such certificate to the Major Shareholder. e. Shareholder Rights/Additional Securities. Subject to the terms hereof, the Major Shareholder shall have all the rights of a shareholder with respect to such Founding Shares while they are held in escrow, including without limitation, the right to vote the Founding Shares and receive any cash dividends declared thereon. If, from time to time during the term of the Company's Repurchase Option, there is (i) any stock dividend, stock split or other change in the Founding Shares, or (ii) any merger or sale of all or substantially all of the assets or other acquisition of the Company, any and all new, substituted or additional securities to which the Major Shareholder is entitled by reason of his ownership of the Founding Shares shall be immediately subject to this escrow, deposited with the Escrow Holder and included thereafter as "Founding Shares" for purposes of this Agreement. 1.4 Restriction on Transfer of Unreleased Founding Shares. Except for the escrow described in Section 1.3 or transfer of the Founding Shares to the Company or its assignees contemplated by Section 1.1, none of the Founding Shares or any beneficial interest therein shall be transferred, encumbered or otherwise disposed of in any way until the release of the Founding Shares from the Company's Repurchase Option in accordance with the provisions of this Section 1. After such release, the Founding Shares shall be subject to the restrictions set forth in Section 2. 2. Options to Purchase or Sell. 2.1 Restrictions on Transfer. No sale or other disposition (voluntary or involuntary) of Founding Shares released from the Company's Repurchase Option in accordance with the provisions of Section 1 or of other shares of Common Stock of the Company now owned or hereafter acquired by the Major Shareholder (the "Shares") shall be valid unless it is made in accordance with the provisions of this Section 2. 2.2 Right of First Refusal. a. Offer for Sale. In the event, at any time following the date of this Agreement, the Major Shareholder or his transferee -3- 92 desires to accept a bona fide third-party offer to sell or transfer in any manner Shares not or no longer subject to the Company's Repurchase Option, he shall first offer such Shares for sale to the Company at the same price, and upon the same terms (or terms as similar as reasonably possible) upon which he is proposing or is to dispose of such Shares, and shall at the same time provide notice to the Investors of such offer and its terms. Such right of first refusal shall be provided to the Company for a period of twenty-one (21) days following receipt by the Company of written notice by Major Shareholder of the terms and conditions of said proposed sale or transfer, or twenty-one (21) days following the setting of a price under Section 2.2(c) (when the price is determined under that Section). In the event that the Company does not exercise its right of first refusal for the full number of Shares, the Major Shareholder or his transferee shall then offer such remaining Shares to the Investors in the same manner as provided herein to the Company, with the Investors' right of first refusal extending for a similar twenty-one (21) day period. Each Investor shall be entitled to purchase a pro rata share of such remaining Shares equal to the number of shares of Common Stock, and other securities convertible into or exercisable for Common Stock, (together "Common Stock Equivalents") then held by the Investor, divided by the number of Common Stock Equivalents held by those Investors electing to exercise their option. In the event the Shares are not disposed of within ninety (90) days following lapse of the period of the right of first refusal provided to the Investor, they shall once again be subject to the right of first refusal herein provided. b. Involuntary Transfers. In the event, at any time following the date of this Agreement, of any transfer by operation of law or other involuntary transfer (including a transfer pursuant to dissolution of marriage) of all or a portion of the Shares, the Company (or the Investors, if the Company shall refuse its option) shall have an option to purchase all of the Shares transferred. Upon such a transfer, the person acquiring the Shares shall promptly notify the Secretary of the Company and the Investors of such transfer. The right to purchase such Shares shall be provided to the Company for a period of twenty-one (21) days following receipt by the Company of written notice by the person acquiring the Shares.

The Board of Directors and the Major Shareholder shall select such analyst within thirty (30) days after receipt of notice that the Major Shareholder is disputing the price set by the Board of Directors. If the Board is not notified of any such dispute within such ten (10) days period, the decision of the Board of Directors as to the purchase price shall be final. Any time required to resolved a dispute shall be added to the twenty-one (21) day period in which the Company may exercise its right to purchase. 2.3 Right of Co-Sale. Within forty-two (42) days after receipt of the offer delivered under Section 2.2(a), each Investor shall also notify the Major Shareholder and the Company whether it exercises its right of co-sale under the provisions of this Section 2.3. In the event that the Company and the Investors do not exercise their right of first refusal set forth in Section 2.2 above for all of the Shares proposed to be sold, and the Major Shareholder continues to hold Shares which he proposes to sell to the prospective purchaser (the "Co-Sale Shares"), then each of the Investors may notify the Major Shareholder of its desire to sell to the prospective purchaser the shares of stock of the Company which such Investor then holds on the same terms as those on which the Major Shareholder proposes to sell the Co-Sale Shares. The maximum number of shares of stock of the Company which an Investor shall be entitled to sell pursuant to this Section 2.3 shall be equal to that number obtained by multiplying (x) the total number of Co-Sale Shares by (y) a fraction, the numerator of which is the total number of shares of Common Stock Equivalents then held by the Investor and the denominator of which is double the total number of shares of Common Stock Equivalents then held in the aggregate by the Major Shareholder and the Investors. If an Investor elects to sell to the prospective purchaser, then the Major Shareholder shall assign as -5- 94 much of his interest in the agreement of sale with the prospective purchaser as the Investor shall be entitled to and shall accept hereunder. 2.4 Sale after Notice. If within forty-two (42) days after receipt by the Investors of copies of the initial written notice pursuant to Section 2.2(a) above, the Investors do not send notice pursuant to Section 2.3 above, then the Major Shareholder shall be free to sell the stock to such prospective purchaser but only on the same terms and conditions as contained in the notice sent to the Investors. In the event the Shares are not disposed of within ninety (90) days following the lapse of the right of co-sale granted pursuant to Section 2.3 to the Investors, they shall once again be subject to the rights of first refusal and co-sale herein provided. 2.5 Excluded Transfers.

All transferees of Shares or any interest therein pursuant to this Section 2.5 shall be required as a condition of such transfer to agree in writing in the form satisfactory to the Company that they will receive and hold such Shares or interests subject to the provisions of this Agreement, including, insofar as applicable, the Company's and the Investor's right of first refusal in Section 2.2 and the Investor's right of co-sale in Section 2.3. Any sale or transfer of the Shares shall be void unless the provisions of this Agreement are met. 2.6 Termination of Rights. a. Transfers in Accordance with Agreement. Any Shares transferred in accordance with the terms of Sections 2.2, 2.3 or 2.4 above, shall no longer be subject to or covered by this Agreement. b. Public Market. The rights of the Company and the Investors pursuant to this Section 2 shall end at such time as a public market exists for the Company's Common Stock (or any other stock issued to the Major Shareholder in exchange for the Shares). For the purpose of this Agreement, a "public market" shall be deemed to exist if (A) such stock is listed on a national securities exchange (as that term is used in the Securities Exchange Act of 1934) or (B) such stock is traded on the over-the-counter market and prices are published daily on business days in a recognized financial journal.

With respect to any stock to be transferred pursuant to Section 2.2(b), the price per Share shall be a price set by the Board of Directors of the Company which will reflect the current value of the Shares in terms of present earnings and future prospects for the Company. The Company shall notify the Major Shareholder or his executor of the price so determined within twenty-one (21) days after receipt by it of written notice of the transfer or proposed transfer of the Shares. If the Major Shareholder or his executor disputes the price as set by the Board of Directors by giving notice to the Company within ten (10) days after being informed of the price, the price of the Shares shall be determined by an independent financial analyst selected jointly by the Board of Directors of the Company and the Major Shareholder, with the cost of such determination to be divided equally between the Company and the Major Shareholder. The Board of Directors and the Major Shareholder shall select such analyst within thirty (30) days after receipt of notice that the Major Shareholder is disputing the price set by the Board of Directors. If the Board is not notified of any such dispute within such ten (10) days period, the decision of the Board of Directors as to the purchase price shall be final. Any time required to resolved a dispute shall be added to the twenty-one (21) day period in which the Company may exercise its right to purchase. (c) Right of Co-Sale. Within forty-two (42) days after receipt of the offer delivered under Section 2.2(a), each Investor shall also notify the Major Shareholder and the Company whether it exercises its right of co-sale under the provisions of this Section 2.3. In the event that the Company and the Investors do not exercise their right of first refusal set forth in Section 2.2 above for all of the Shares proposed to be sold, and the Major Shareholder continues to hold Shares which he proposes to sell to the prospective purchaser (the "Co-Sale Shares"), then each of the Investors may notify the Major Shareholder of its desire to sell to the prospective purchaser the shares of stock of the Company which -5- 113 such Investor then holds on the same terms as those on which the Major Shareholder proposes to sell the Co-Sale Shares. The maximum number of shares of stock of the Company which an Investor shall be entitled to sell pursuant to this Section 2.3 shall be equal to that number obtained by multiplying (x) the total number of Co-Sale Shares by (y) a fraction, the numerator of which is the total number of shares of Common Stock Equivalents then held by the Investor and the denominator of which is double the total number of shares of Common Stock Equivalents then held in the aggregate by the Major Shareholder and the Investors. If an Investor elects to sell to the prospective purchaser, then the Major Shareholder shall assign as much of his interest in the agreement of sale with the prospective purchaser as the Investor shall be entitled to and shall accept hereunder. (d) Sale after Notice. If within forty-two (42) days after receipt by the Investors of copies of the initial written notice pursuant to Section 2.2(a) above, the Investors do not send notice pursuant to Section 2.3 above, then the Major Shareholder shall be free to sell the stock to such prospective purchaser but only on the same terms and conditions as contained in the notice sent to the Investors. In the event the Shares are not disposed of within ninety (90) days following the lapse of the right of co-sale granted pursuant to Section 2.3 to the Investors, they shall once again be subject to the rights of first refusal and co-sale herein provided. (e) Excluded Transfers. The Major Shareholder may transfer all or part of the Shares to an ancestor, descendant, spouse, or a custodian or a trustee, including a trustee of a voting trust, for the account of an ancestor, descendant, spouse, or the Major Shareholder; provided, however, that this Agreement shall be binding upon such transferee. All transferees of Shares or any interest therein pursuant to this Section 2.5 shall be required as a condition of such transfer to agree in writing in the form satisfactory to the Company that they will receive and hold such Shares or interests subject to the provisions of this Agreement, including, insofar as applicable, the Company's and the Investor's right of first refusal in Section 2.2 and the Investor's right of co-sale in Section 2.3. Any sale or transfer of the Shares shall be void unless the provisions of this Agreement are met. (f) Termination of Rights. (i) Transfers in Accordance with Agreement. Any Shares transferred in accordance with the terms of Sections 2.2, 2.3 or 2.4 above, shall no longer be subject to or covered by this Agreement. -6- 114 (ii) Public Market. The rights of the Company and the Investors pursuant to this Section 2 shall end at such time as a public market exists for the Company's Common Stock (or any other stock issued to the Major Shareholder in exchange for the Shares). For the purpose of this Agreement, a "public market" shall be deemed to exist if (A) such stock is listed on a national securities exchange (as that term is used in the Securities Exchange Act of 1934) or (B) such stock is traded on the over-the-counter market and prices are published daily on business days in a recognized financial journal.
