The Royalty Statement shall be in reasonably specific detail, on a country-by-country basis, and segmented according to sales by Spring Bank and each sublicensee.

(e)

Each Party agrees to assist the other Party in claiming exemption from such deductions or withholdings under any double taxation or similar agreement or treaty from time to time in force.

(h)

Notwithstanding any other provision of this Agreement, if either Party is prevented from paying any payments by virtue of the Applicable Laws of the country from which the payment is to be made, then such payment may be paid by depositing funds in the currency in which it accrued to the Receiving Party’s account in a bank acceptable to the Receiving Party in the country whose currency is involved.

(i)

In the event Spring Bank or its sublicensee(s) receive any non-monetary consideration in connection with the sale of the Product, the Net Sales of such Product, or any Sublicensing Revenue, shall be calculated based on the fair market value of such other consideration. Spring Bank shall disclose the terms of such arrangement to Micrologix and the Parties shall endeavour in good faith to agree on such fair market value as promptly as possible.

Micrologix shall transfer the files relating to the prosecution of the Micrologix Patent Rights listed on Exhibit A to patent counsel of Spring Bank’s choosing immediately after the execution of this Agreement, unless there are filings required or office actions which require a response within thirty (30) days of execution, in which case, Spring Bank may elect to retain Micrologix’ patent attorneys to make such filing or respond to such office action. As of the Effective Date, Spring Bank has elected to assume prosecution of the patent applications in those countries and patent offices listed on Exhibit 1.1(y). With respect to patent applications that are about to enter the national phase, Spring Bank shall notify Micrologix in which countries it intends to pursue prosecution at least 45 days prior to the date that an election is required.

(b)

In the event Spring Bank intends to abandon the prosecution or maintenance of all or any part of Micrologix Patent Rights claiming the Product or ORI-9020 in any country in the Territory (which it shall only be permitted to do in the event it has a reasonable belief that obtaining or maintaining rights are not possible using Commercially Reasonable Efforts), Spring Bank shall notify Micrologix no less than sixty (60) days (or such shorter period of time if there is a shorter period of time required by a the applicable governmental authority) prior to the date it intends to abandon the prosecution or maintenance, as applicable, of any such Micrologix Patent Rights.

Thereafter, Micrologix shall have the right but not the obligation to prosecute or maintain any such Micrologix Patent Right at its expense.

(d)

Micrologix shall, at no cost or expense to Micrologix, make available to Spring Bank or its authorized attorneys, agents or representatives, its employees, agents or consultants necessary or appropriate to enable Spring Bank to file, prosecute and maintain patent applications covering the Product for a reasonable period of time sufficient for Spring Bank to obtain the assistance it needs from such personnel. Spring Bank shall provide Micrologix with copies of all correspondence, documentation and/or submissions provided to, and received from, U.S. PTO and comparable authorities in which Spring Bank is responsible for prosecuting and maintaining the Micrologix Patent Rights.

8.2

Infringement by Others

Each party shall promptly inform the other party of any suspected infringement of any Micrologix Patent Right by a third party. Regardless of which party in fact brings suit, the parties shall reasonably cooperate with each other with respect to any litigation, action, suit, claim or other proceeding under this . Without limiting the generality of the foregoing, the non-litigating party agrees to cooperate reasonably in any such litigation, action, suit, claim or other proceeding as may be requested by or necessary to the litigating party including without limitation, joining any such proceeding as a party, executing all necessary documents, supplying essential documentary evidence and making available essential witnesses then in its employment or engaged as a consultant. Each party shall have the right to institute an action for infringement of the Micrologix Patent Rights against such third party in accordance with the following:

(a)

Within 30 days of notification, if the parties agree to institute suit jointly, the suit shall be brought in both their names, the out-of-pocket costs thereof shall be borne equally, and any recovery or settlement shall be shared equally. The parties shall agree to the manner in which they shall exercise control over such action. Each party may, if it so desires, also be represented by separate counsel of its own selection, the fees for which counsel shall be paid by such party.

(b)

If the parties do not institute suit jointly within 30 days of notification as set forth above, Spring Bank shall be empowered to bring suit in its own name to enjoin such infringement. Spring Bank shall bear the entire cost of such litigation and shall be entitled to retain the entire amount of any recovery or settlement.

(c)

In the event that Spring Bank does not terminate such infringement or initiate steps to do so within six months of learning of such infringement, Micrologix may bring suit against infringer at its sole expense and shall be entitled to retain the entire amount of any recovery or settlement.

(d)

Should either party commence a suit under the provisions of Section 8.2 and thereafter elect to abandon the same, it shall give timely notice to the other party who may, if it so desires, continue prosecution of such suit, provided, however, that the sharing of expenses and any recovery in such suit shall be as agreed upon between the parties.

8.3

Infringement Claimed by Third Parties

(a)

In the event a Third Party commences, or threatens to commence, any proceeding against a party to this Agreement alleging infringement of a Third Party’s intellectual property rights by the manufacture, use, sale, offer for sale, export and/or import by Spring Bank, its Affiliates or sublicensees of the Product, the Party against whom such proceeding is threatened or commenced shall give prompt notice to the other Party (“Infringement Notice”).

(b)

Spring Bank may (but shall have no obligation to do so) control the defense and settlement of any such proceeding under this Section 8.3; provided that Spring Bank notifies Micrologix that it intends to exercise such option at the time Spring Bank gives Micrologix the Infringement Notice or if Spring Bank is not the Party giving an Infringement Notice, then within thirty (30) days after receipt of the Infringement Notice from Micrologix. If Spring Bank fails to notify Micrologix of its intent to exercise such option within the time periods required by this Section 8.3(b) or if Spring Bank notifies Micrologix within such time periods that it does not intend to exercise such option, Micrologix shall then control the defense and settlement of any such proceeding in accordance with the terms hereof.

(c)

The litigating party shall pay all Costs (including unrecovered Costs) in connection with any Proceeding under this Section 8.3. The litigating party shall be entitled to retain the entire amount of any recovery or settlement.

8.4

Co-operation with Other Licensees

Spring Bank acknowledges that Micrologix may grant to licensees rights in the Micrologix Technology in the Territory in respect of fields outside the Field. If Micrologix grants such rights to other licensees, in the event of any litigation in respect of:

(a)

fields outside of the Field that may reasonably affect Spring Bank’s use of the Micrologix Technology in the Field or the use or sale of Products by Spring Bank; or

(b)

the Field that may reasonably affect Micrologix or one or more of Micrologix’s licensee’s use of the Micrologix Technology outside the Field or the manufacture, use or sale of products outside the Field by Micrologix or one or more other such licensee(s);

then Micrologix, Spring Bank and such other licensee(s) will use good faith efforts to determine jointly the course of action, if any, necessary or appropriate to prosecute or defend the litigation. Micrologix will use Commercially Reasonable Efforts to include in its other license agreements, provisions that allow the participation of Spring Bank as contemplated herein. If Micrologix is unable to include in any such other license agreement such provisions, then with respect to the licensee under such other license agreement, Spring Bank shall not be bound by the terms and conditions of this Section 8.4.

Each Party shall promptly notify the other Party upon discovery of any unauthorized use or disclosure of the other Party’s Confidential Information.

ARTICLE 12 ADDITIONAL COVENANTS OF THE PARTIES

12.1

Launch of Competitive Product by Spring Bank

Spring Bank hereby agrees that in the event Spring Bank and/or its Affiliates develop, in-license, market, sell, promote, distribute or have marketed, or have sold any product in the Field (a “Competitive Product”) during the Term, directly for themselves or by a Third Party, licensee or sublicensee on behalf of Spring Bank and/or its Affiliates, Spring Bank’s rights with respect to such country under this Agreement shall terminate and revert to Micrologix. Notwithstanding the foregoing, if Spring Bank or an Affiliate acquires an entity or all or substantially all of the assets of an entity during such period of time and such entity distributes or such assets include a Competitive Product, Spring Bank, or its Affiliate(s), shall have one hundred twenty (120) days in which to divest itself of such Competitive Product or to otherwise cease distribution of such Competitive Product, and Spring Bank shall not be in violation of this Section if it so divests or ceases distribution within such one hundred twenty (120) day period. The Parties mutually agree that Spring Bank’s (or Affiliates’) commercialization, as described above, of any Competitive Product shall not be deemed a breach of this Agreement, and Micrologix sole recourse for such an event shall be that as described in this Section 12.1 only.

12.2

Records and Audits

(a)

Each Party shall keep or cause to be kept true, accurate and complete books and records as are required to determine, in a manner consistent with accrual method of accounting in accordance with GAAP, any sums or credits due under this Agreement during the Term and for a period of three years thereafter or as otherwise required to comply with applicable laws.

(b)

With regard to sums or credits due or related reports, at the request (and expense) of Micrologix, Spring Bank shall permit Micrologix and/or an independent certified public accountant selected by Micrologix and reasonably acceptable to Spring Bank to audit and/or inspect only those books and records of Spring Bank as may be necessary to determine, with respect to any calendar year ending no more than three years prior to Micrologix’s request, the completeness and accuracy of any financial reports made and/or any sums or credits due under this Agreement. Any such independent accounting firm shall be subject to the confidentiality provisions of this Agreement. Such inspection shall be conducted during Spring Bank’s normal business hours, no more than once in any twelve (12) month period and upon at least thirty (30) days prior written notice by Micrologix. If Micrologix concludes that such payments were underpaid during the periods reviewed by Micrologix and/or its accountants, Micrologix shall pay Spring Bank the amount of any such underpayments, plus interest at a rate equal to the Prime Rate of Interest, within thirty (30) days of the date Micrologix delivers to Spring Bank the report so concluding that such payments were underpaid. If Micrologix and/or its accounting firm concludes that such payments were overpaid during such period, Micrologix shall pay to Spring Bank the

amount of any such overpayments, without interest, within thirty (30) days of the date Micrologix delivers to Spring Bank the report so concluding that such payments were overpaid. Micrologix shall bear the full cost of such audit unless such audit discloses an underpayment by more than five percent (5%) of the amount due during such period. In such case, Spring Bank shall bear the full cost of such audit. In the event Spring Bank does not agree with the conclusions of such report, (whether such payments were underpaid or overpaid), then Spring Bank shall notify Micrologix within thirty (30) days after receipt of such report. Thereafter, the Parties shall in good faith try and resolve such differences. If the Parties are unable to reach a mutual agreement within fifteen (15) days after the date of notice then independent auditors of each Party shall meet and select an independent accounting firm (being an accounting firm not used by Micrologix) to make the final determination within fifteen (15) days thereafter. The determination of such independent accounting firm shall be binding and conclusive on the Parties, and the cost of such firm shall be borne by the Party against whom the determination by such firm is made.

12.3

Further Actions

Upon the terms and subject to the conditions hereof, each of the Parties shall use its Commercially Reasonable Efforts to take, or cause to be taken, all appropriate action and do, or cause to be done, all things necessary or advisable under applicable laws or otherwise to consummate and make effective the transactions contemplated by this Agreement.

ARTICLE 14 DISPUTE RESOLUTION/DAMAGES

14.1

Disputes

The Parties recognize that disputes as to certain matters may from time to time arise during the Term which relate to either Party’s rights and/or obligations hereunder or to the interpretation, performance, breach, or termination of this Agreement, (a “Dispute”). It is the objective of the Parties to establish procedures to facilitate the resolution of a Dispute in an expedient manner by mutual cooperation and without resort to litigation. To accomplish this objective, the Parties agree to follow the procedures set forth in this Article 14 if and when a Dispute arises under this Agreement.

Except as provided in Section 14.2, disputes among the Parties will be resolved as recited in this . Any Disputes relating to this Agreement shall be promptly presented to the Chief Executive Officers of Micrologix and Spring Bank, or their respective designees (who must be members of a Party’s senior management) for resolution. From the date of referral of a Dispute to the Chief Executive Officers or their designees of the Parties and until such time as any matter has been resolved by the Parties or has been finally settled by arbitration hereunder, the running of the cure periods (if any) as to which a Party must cure a breach that is part of the subject matter of any Dispute shall be suspended. In the event that the Chief Executive Officers of Micrologix and Spring Bank, or their respective designees, cannot after good faith negotiations resolve the Dispute within 10 days (or such other period of time as mutually agreed to by the Parties in writing) of being requested by a Party to resolve a Dispute, the Parties agree that such Dispute shall be resolved by binding arbitration in accordance with this Section 14.1.

If a Party intends to begin arbitration to resolve such Dispute, such Party shall provide written notice (the “Arbitration Notice”) to the other Party informing such other Party of such intention and the issues to be resolved. Any arbitration hereunder shall be conducted pursuant to the Commercial Arbitration Rules of the American Arbitration Association (“AAA”), including the Supplementary Procedures for Large Complex Disputes (the “AAA Rule”) except as modified herein. The arbitration shall be conducted by a panel of three (3) arbitrators (the “Panel”) to be mutually agreed upon by the Parties and appointed by the AAA. The arbitrators shall be industry experts experienced in the issues comprising the Dispute and shall have no past, present or anticipated future affiliation with either Party. If the Parties are unable to agree upon all or any number of the three (3) mutually acceptable arbitrators within thirty (30) days after the filing of the Arbitration Notice, the AAA shall promptly appoint the arbitrator(s) to complete the Panel in accordance with the criteria set forth in this Section 14.1. The arbitration shall take place in New York, New York. The Panel shall apply the laws of the State of New York, without regard to its conflicts of laws provisions. The Panel shall issue appropriate protective orders to protect each Party’s Confidential Information. If a Party can demonstrate to the Panel that the complexity of the issue or other reasons warrant the extension of one or more timetables in the AAA Rules, the Panel may extend such timetables but in no event shall the proceeding extend more than twelve (12) months from the date of filing of the Arbitration Notice with the AAA. The Panel’s decision shall be in writing. The Panel shall have the authority to award any remedy allowed by law or in equity, including without limitation compensatory damages, pre-judgment interest and to grant final, complete, interim, or interlocutory relief, including without limitation specific performance, injunctions and other equitable relief, but not punitive or other damages set forth in Section 14.3 and each Party shall be deemed to have waived any right to such excluded damages. Each Party shall bear its own costs, fees and expenses in the arbitration and shall share equally the Panel’s fees, unless the Panel determines that its fees are to be paid by the non-prevailing Party.

14.2

Injunctive Relief

Nothing in this Agreement shall prevent either Party from seeking a temporary restraining order or injunction against the other Party as required to prevent such other Party’s misuse of the intellectual property or Confidential Information of the other Party seeking such temporary restraining order or injunction. The Parties understand and agree that because of the difficulty in measuring economic losses to the non breaching Party as a result of a breach of the covenants set forth in this Agreement respecting intellectual property and Confidential Information and because of the immediate and irreparable damage that may be caused to the non breaching

Party for which monetary damages would not be a sufficient remedy, the Parties agree that the non breaching Party will be entitled to seek specific performance, temporary and permanent injunctive relief, and such other equitable remedies to which it may then be entitled against the breaching Party. This Section 14.2 shall not limit any other legal or equitable remedies that the non breaching Party may have against the breaching Party.

14.3

No Consequential Damages

IN NO EVENT SHALL EITHER PARTY BE LIABLE TO THE OTHER FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL OR PUNITIVE DAMAGES INCURRED BY EITHER PARTY UNDER THIS AGREEMENT OR OTHERWISE.

ARTICLE 15 MISCELLANEOUS

15.5

Waiver

Except as specifically provided for herein, the waiver from time to time by either of the Parties of any of their rights or their failure to exercise any remedy shall not operate or be construed as a continuing waiver of same or of any other of such Party’s rights or remedies provided in this Agreement.

15.6

Severability

In case any provision of this Agreement shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

Micrologix hereby represents and warrants to the Company as follows:

Authorization. Micrologix has full power and authority to enter into this Agreement and this Agreement constitutes a valid and legally binding obligation of Micrologix. All corporate action on the part of Micrologix, its officers, directors and stockholders necessary for the authorization, execution and delivery of this Agreement, the License Agreement and the performance of Micrologix' obligations hereunder (including the acceptance of the Shares) has been taken, and this Agreement constitutes a valid and legally binding obligation of Micrologix, enforceable in accordance with its terms, except (i) as limited by applicable bankruptcy, insolvency, reorganization, moratorium, and other laws of general application affecting enforcement of creditors' rights generally and (ii) as limited by laws relating to the availability of specific performance, injunctive relief, or other equitable remedies.

4.2

Purchase Entirely for Own Account. This Agreement is made with Micrologix in reliance upon Micrologix' representation to the Company, which by Micrologix execution of this Agreement Micrologix hereby confirms, that it is acquiring the Shares for investment for its own account, not as a nominee or agent, and not with a view to the resale or distribution of any part thereof to any person, including a resale or distribution of any part thereof in the United States or to a Unites States resident, and that Micrologix has no present intention of selling, granting any participation in, or otherwise distributing the same. By executing this Agreement, Micrologix further represents that Micrologix does not have any contract, undertaking, agreement or arrangement with any person to sell, transfer or grant participations to such person, including persons in the United States or to a United States resident, regarding any of the Shares. .

4.3

Reliance Upon Micrologix' Representations. Micrologix understands that the Shares are not registered under the Securities Act on the ground that the issuance of the Shares provided for hereunder is exempt from registration under the Securities Act pursuant to Section 4(2) thereof and/or Regulations D thereunder, and that the Company's reliance on such exemptions is predicated on the Micrologix’ representations set forth herein. Micrologix acknowledges that the basis for the exemption(s) may not be present if, notwithstanding such representations, the Micrologix has in mind merely acquiring the Shares for a fixed or determinable period in the future, for sale if the market rises, or for sale if the market does not rise. Micrologix represents that it has no such intentions.

4.4

Micrologix further represents that it has asked questions and received answers from the Company regarding the Shares and the business, properties, prospects, and financial condition of the Company and to obtain such additional information (to the extent the Company possessed such information or could acquire it without unreasonable effort or expense) necessary to verify the accuracy of any information furnished to Micrologix or to which it had access.

4.5

Investment Experience. Micrologix represents that it is experienced in evaluating and investing in securities of companies in the early stages of product research and development and acknowledges that it able to fend for itself, can bear the economic risk of the total loss in value of the Shares, and has such knowledge and experience in financial and business matters that it is capable of evaluating the merits and risks of the investment in the Shares.

VOTING AGREEMENT. Micrologix agrees that if it or any of its affiliates shall convert the Shares into Common Stock of the Company, and at such time or at any time thereafter, Micrologix and its affiliates shall, in the aggregate, own 20% or more of the capital stock in the Company which entitles them alone or in the aggregate to vote in any election for the Board of Directors of the Company (including a vote to fill a vacancy), then Micrologix and each such affiliate shall execute the Voting Agreement attached hereto as Exhibit C.

(a)

“Initial Public Offering” means an initial public offering of the Company’s Common Stock in the United States pursuant to the Securities Act.

(b)

“Holder” means any holder of the Shares or the Common Stock into which the Shares are convertible.

(c)

Restricted Securities shall mean any of the Shares and the Common Stock issued or issuable upon the conversion of the Shares,all shares of Common Stock issued or issuable in respect thereof by way of stock splits, stock dividends, stock combinations, recapitalizations or like occurrences, and any other shares of Common Stock or other securities of the Company which may be issued hereafter to any of the Holders which are convertible into or exercisable for shares of Common Stock (including, without limitation, other classes or series of Preferred Stock, warrants, options or other rights to purchase Common Stock or convertible debentures or other convertible debt securities) and the Common Stock issued or issuable upon such conversion or exercise of such other securities, which have not been sold (a) pursuant to an effective registration statement filed pursuant to the Securities Act, or (b) pursuant to Rule 144 or Rule 144A promulgated by the Commission under the Securities Act.

(d)

7.2

Demand Registrations.

(a)

At any time, and from time to time, following the six month period following the Company’s Initial Public Offering, Micrologix may request in writing registration under the Securities Act of all or part of its Restricted Shares (a “Demand Registration”). Each request for a Demand Registration shall specify the approximate number of Restricted Shares requested to be registered and the anticipated per share price range for such offering. Subject to Section 7.2(e) below, the Company will include in such registration or prospectus all Restricted Shares with respect to which the Company has received a written request for inclusion within 15 days after the receipt of the Company’s notice. All registrations and qualifications requested pursuant to this Section 7.2(a) are referred to herein as “Demand Registrations.” Subject to Section 7.2(c), Micrologix will be entitled to request two Demand Registrations, for which the Company shall pay all registration expenses to the fullest extent permitted by law, other than any underwriting fees, expenses and discounts, which shall be borne by Micrologix.

(b)

The Company will not include in any Demand Registration any securities which are not Restricted Shares without the prior written consent of Micrologix, which shall not be unreasonably withheld or delayed. If a Demand Registration is an underwritten offering and the managing underwriters advise the Company in writing (with a copy to each party hereto requesting registration or qualification for distribution by prospectus of Restricted Shares) that, in their good faith opinion, the number of Restricted Shares and, if permitted hereunder, other securities requested to be included in such offering, exceeds the number of Restricted Shares and other securities, if any, which can be sold therein without adversely affecting the marketability of the offering, the Company will include in such offering, prior to the inclusion of any securities which are not Restricted Shares, the number of Restricted Shares requested to be included which, in the opinion of such underwriters, can be sold without adversely affecting the marketability of the offering.

(c)

The Company will not be obligated to effect any Demand Registration within six (6) months after the effective date or date of final receipt of a previous Demand Registration. The Company may, on no more than one occasion during any 12-month period, postpone for up to an aggregate of 90 days the filing of a prospectus or the effectiveness of a registration statement for a Demand Registration if the Company concludes, following consultation with, and after obtaining the approval of, the board of directors of the Company, that such Demand Registration would reasonably be expected to have a materially adverse effect on any proposal or plan by the Company to engage in any material acquisition of assets (other than in the ordinary course of business) or any financing transaction, merger, amalgamation,

consolidation, tender offer or similar transaction or otherwise would have a material adverse effect on the business, assets, operations, or financial condition of the Company; provided, however, that in such event, the requesting party will be entitled to withdraw such request and, if such request is withdrawn promptly, such Demand Registration will not count as one of the permitted Demand Registrations hereunder and the Company will pay, to the fullest extent permitted by applicable law, all registration expenses in connection with such registration or prospectus, other than any underwriting fees, expenses and discounts, which shall be borne by the requesting party or parties.

(d)

On any Demand Registration, Micrologix, at its sole expense, will have the right to select the investment banker(s) and manager(s) from firms of national reputation in the U.S. to administer the offering, subject to the Company’s approval which will not be unreasonably withheld or delayed.

7.3

Piggyback Registration.

(a)

Each time that the Company proposes for any reason to register any of its securities under the Securities Act, other than pursuant to a Demand Registration or the Company’s initial public offering or pursuant to a registration statement on Form S-8 or similar or successor forms (collectively, “Excluded Forms”), the Company shall promptly give written notice of such proposed registration to all Holders of Restricted Securities, which shall offer such Holders the right to request inclusion of any Restricted Shares in the proposed registration.

(b)

Each Holder of Restricted Securities shall have 30 days from the receipt of such notice to deliver to the Company a written request specifying the number of Restricted Shares such Holder intends to sell and the Holder’s intended method of disposition.

(c)

In the event that the proposed registration by the Company is, in whole or in part, an underwritten public offering of securities of the Company, any request under Section 7.3(b) may specify that the Restricted Shares be included in the underwriting (i) on the same terms and conditions as the shares of Common Stock, if any, otherwise being sold through underwriters under such registration, or (ii) on terms and conditions comparable to those normally applicable to offerings of common stock in reasonably similar circumstances in the event that no shares of Common Stock other than Restricted Shares are being sold through underwriters under such registration.

(d)

Upon receipt of a written request pursuant to Section 7.3(b), the Company shall promptly use reasonable commercial efforts to cause all such Restricted Shares to be registered under the Securities Act, to the extent required to permit sale or disposition as set forth in the written request.

(e)

Notwithstanding the foregoing, if the managing underwriter of any such proposed registration determines and advises in writing that, in their good faith opinion, the inclusion of all Restricted Shares proposed to be included in the underwritten public offering, together with any other issued and outstanding shares of Common Stock proposed to be included therein by holders other than the Holders of Restricted Securities (such other shares hereinafter collectively referred to as the “Other Shares”), would interfere with the successful marketing of the Company’s securities, then the total number of such securities proposed to be included in such underwritten public offering shall be reduced to a number deemed satisfactory by such managing underwriter, provided that the securities to be included shall be determined in the following sequence:

(i)

If the offering was proposed by or for the account of holders of the Company’s securities other than the Holders of Restricted Securities (the "Proposing Holders"): (A) first, the securities requested to be registered by the Proposing Holders, (B) second, the Restricted Shares requested to be registered by the Holders (pro rata based on the amount of Restricted Shares held by such Holders), (C) third, securities requested to be registered by holders of the Company’s securities other than the Holders or the Proposing Holders, and (D) fourth, securities requested to be registered for the account of the Company,

(ii)

If the offering was proposed by or for the account of the Company: (A) first, the securities proposed to be offered for the account of the Company, (B) second, the Restricted Shares requested to be registered by the Holders (pro rata based on the amount of Restricted Shares held by such Holders), and (C) third, securities requested to be registered by the holders of the Company’s securities other than the Holders.

7.4

Preparation and Filing. If and whenever the Company is under an obligation pursuant to the provisions of this Section 3 to use commercially reasonable efforts to effect the registration of any Restricted Shares, the Company shall, as expeditiously as practicable:

(a)

prepare and file with the Securities and Exchange Commission (the “Commission”) a registration statement or prospectus with respect to such securities and use commercially reasonable efforts to cause such registration statement or prospectus to become and remain effective in accordance with Section 7.4(b) hereof;

(b)

prepare and file with the Commission such amendments and supplements to such registration statement and the prospectus used in connection therewith as may be necessary to keep such registration statement effective until the earlier of (i) the sale of all Restricted Shares covered thereby or (ii) nine months;

(c)

furnish to each Holder whose Restricted Shares are being registered pursuant to this Section 7 such number of copies of any summary prospectus or other prospectus, including a preliminary prospectus, in conformity with the requirements of the Securities Act, as the case may be, and such other documents as such Holder may reasonably request in order to facilitate the public sale or other disposition of such Restricted Shares;

(d)

use commercially reasonable efforts to register or qualify the Restricted Shares covered by such registration statement or prospectus under the securities or blue sky laws of such jurisdictions as each holder whose Restricted Shares are being registered pursuant to this Section 7 shall reasonably request and do any and all other acts or things which may be necessary or advisable to enable such Holder to consummate the public sale or other disposition in such jurisdictions of such Restricted Shares; provided, however, that the Company shall not be required to consent to general service of process for all purposes in any jurisdiction where it is not then subject to process, qualify to do business as a foreign corporation where it would not be otherwise required to qualify or submit to liability for state or local taxes where it is not otherwise liable for such taxes;

(e)

at any time when a prospectus covered by such registration statement and relating thereto is required to be delivered under the Securities Act within the appropriate period mentioned in Section 7.3(b) hereof, notify each Holder whose Restricted Shares are being registered pursuant to this Section 7 of the happening of any event as a result of which the prospectus included in such registration, 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, at the request of such holder, prepare, file and furnish to such holder a reasonable number of copies of a supplement to or an amendment of such prospectus as may be necessary so that, as thereafter delivered to the purchasers of such shares, such prospectus shall not include an untrue statement of a material fact or omit 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;

(f)

if the Company has delivered preliminary or final prospectuses to the Holders of Restricted Shares that are being registered pursuant to this Section 7 and after having done so the prospectus is amended to comply with the requirements of the Securities Act, the Company shall promptly notify such holders and, if requested, such holders shall immediately cease making offers of Restricted Shares and return all prospectuses to the Company. The Company shall promptly provide such holders with revised prospectuses and, following receipt of the revised prospectuses, such holders shall be free to resume making offers of the Restricted Shares;

(g)

upon receipt of such confidentiality agreements as the Company may reasonably request, make available for inspection by any Holder and any underwriter participating in any disposition pursuant to such registration statement or prospectus and any attorney, accountant or other agent retained by any Holder or underwriter, all financial and other records, pertinent corporate documents and documents relating to the business of the Company, and cause the Company’s officers, directors, employees and independent accountants to supply all information reasonably requested by any such Holder, underwriter, attorney, accountant or agent in connection with such registration statement or prospectus;

(h)

otherwise use its reasonable commercial efforts to comply with all applicable rules and regulations of the Commission; (h) advise the Holder promptly after it receives notice or obtains knowledge thereof of the issuance of any stop order suspending the effectiveness of a registration statement which includes the Restricted Shares, or of any order suspending or preventing the use of any related prospectus or cease trading or suspending the qualification of any securities included in such registration statement, for sale in any jurisdiction, or the initiation or threatening of any proceeding for that purpose and promptly use its best efforts to prevent the issuance of any such order or its withdrawal if such order has been issued;

(i)

furnish, at the request of any Holder whose Restricted Shares are being registered or qualified pursuant to this Section 7, on the date that such Restricted Shares are delivered to the underwriters for sale in connection with a registration or qualification pursuant to this Section 7, if such securities are being sold through underwriters, or, on the date that the registration statement with respect to such securities becomes effective, if such securities are not being sold through underwriters, (i) an opinion, dated such date, of the counsel representing the Company for the purposes of such registration or qualification, in form and substance as is customarily given to underwriters in an underwritten public offering, addressed to the underwriters, if any, and to the holder or holders making such request, and (ii) a letter dated such date, from the independent certified public accountants of the Company, in form and substance as is customarily given by independent certified public accountants to underwriters in an underwritten public offering, addressed to the underwriters, if any, and to the holder or holders making such request.

Notwithstanding the foregoing, if, after a registration statement becomes effective, the Company becomes engaged in any activity which, in the good faith determination of the Board of Directors, involves information that would have to be disclosed in the registration statement but which the Company desires to keep confidential for valid business reasons, then the Company may at its option by notice to such Holders of Restricted Shares that have included shares in such registration statement or prospectus, require that such Holders cease sales of such shares under such registration statement or prospectus for a period not in excess of ninety days from the date of such notice, such right to be exercised by the Company not more than once in any 12-month period. If in connection therewith, the Company considers it appropriate for such registration statement or prospectus to be amended, the Company shall so amend such registration statement or prospectus as promptly as practicable and such holders shall suspend any further sales of their shares until the Company advises them that such registration statement or prospectus has been amended. The time periods referred to herein during which such registration statement or prospectus must be kept effective shall be extended for an additional number of days equal to the number of days during which the right to sell shares was suspended pursuant to this paragraph.

7.5

Expenses. The Company shall pay all expenses incurred by the Company in complying with this Section 7, including, without limitation, all registration and filing fees (including all expenses incident to filing with the National Association of Securities Dealers, Inc.), fees and expenses of complying with the securities and blue sky laws of all such jurisdictions in which the Restricted Shares are proposed to be offered and sold, printing expenses and fees and disbursements of counsel (including with respect to each registration effected pursuant to Section 7.2 and 7.3, the reasonable fees and disbursements of one counsel for the Holders of Restricted Securities who may be chosen by a majority in interest of the Restricted Shares being registered in such offering); provided, however, that all underwriting discounts and selling commissions applicable to the Restricted Shares shall be borne by the seller or sellers thereof, in proportion to the number of Restricted Shares sold by each such seller or sellers.

7.6

Indemnification.

(a) (i)

In the event of any registration of any Restricted Shares under the Securities Act pursuant to this Section 7, the Company shall indemnify and hold harmless the seller of such shares their affiliates, officers and directors, each underwriter of such shares, if any, each broker or any other person acting on behalf of such seller and each other person, if any, who controls any of the foregoing persons, within the meaning of the Securities Act (“Holder Indemnitees”), against any losses, claims, damages or liabilities, joint or several (collectively “Claims”), to which any of the foregoing persons may become subject under the Securities Act or otherwise, insofar as such Claims (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in any registration statement under which such Restricted Shares were registered under the Securities Act, any preliminary prospectus or final prospectus contained therein, or any amendment or supplement thereto, or any document incident to registration or qualification of any Restricted Shares, or arise out of or are based upon the 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, with respect to any prospectus, necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, or any violation by the Company of the Securities Act or any state securities or blue sky laws applicable to the Company and relating to action or inaction required of the Company in connection with such registration or qualification under the Securities Act or such state securities or blue sky laws; provided however, that the Company is given prompt written notice of the Claims and is given information, reasonable assistance and sole authority to defend and/or settle the claim and provided further, however that the Company shall not settle or admit liability with respect to any such claim which would result in an admission of liability by a Holder Indemnitee without such Holder Indemnitee’s prior written consent, which will not be unreasonably withheld. The Holder Indemnitees shall cooperate with the Company and may, at their option and expense be represented in any such action or proceeding. In addition, the Company shall not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon (1) an untrue statement or alleged untrue statement or omission or alleged omission made in said registration statement, preliminary or final prospectus or amendment or supplement thereto or any document incident to registration or qualification of any Restricted Shares, in reliance upon and in conformity with written information furnished to the Company by such seller, underwriter, broker, other person or controlling person specifically for use in the preparation thereof, or (2) if the Company provides an amended prospectus which corrects any misstatement or omission, any use of a prospectus which does not contain such correction after such correction is made and the prospectus is provided to such seller.

(ii)

In the event of any registration of any Restricted Shares under the Securities Act pursuant to this Section 7 or registration or qualification of any Restricted Shares, the Holders, jointly but not severally, shall indemnify and hold harmless the Company and its directors, officers, employees, agents and affiliates and any other person, if any, who controls any of the foregoing persons, within the meaning of the Securities Act (collectively, “Company Indemnitees”), against any Claims (or actions in respect thereof) which arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in any registration statement under which such Restricted Shares were registered under the Securities Act, any preliminary prospectus or final prospectus contained therein, or any amendment or supplement thereto, or any document incident to registration or qualification of any Restricted Shares, or arise out of or based upon the 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, with respect to any prospectus, necessary to make statements therein, in light of the circumstances under which they were made, not misleading, or any violation of the Securities Act or any state securities or applicable blue sky laws or Canadian securities laws relating to action or inaction required of the Company in connection with such registration or qualification under the Securities Act or such state securities or blue sky laws arising out of or based upon written information furnished to the Company by any such Holder specifically for use in the preparation thereof, provided however, that the Holders are given prompt written notice of the Claims and are given information, reasonable assistance and sole authority to defend and/or settle the claim and provided further, however that the Holders shall not settle or admit liability with respect to any such claim which would result in an admission of liability by a Company Indemnitee without such Company Indemnitee’s prior written consent, which will not be unreasonably withheld. The Company Indemnitees shall cooperate with the Holders and may, at their option and expense be represented in any such action or proceeding.

(b)

Before Restricted Shares held by any prospective seller shall be included in any registration or qualification pursuant to this Section 7, such prospective seller and any underwriter acting on its behalf shall agree in writing to indemnify and hold harmless (in the same manner and to the same extent as set forth in paragraph (a) above) the Company, each director of the Company, each officer of the Company who signs such registration statement or prospectus and any person who controls the Company within the meaning of the Securities Act, with respect to any untrue statement or omission from such registration statement, any preliminary prospectus or final prospectus, or any amendment or supplement thereto, if such untrue statement or omission was made in reliance upon and in conformity with written information furnished to the Company through an instrument duly executed by such seller or such underwriter specifically for use in the preparation of such registration statement, preliminary prospectus, final prospectus or amendment or supplement.

(c)

In order to provide for just and equitable contribution under the Securities Act in any case in which either (i) any holder of Restricted Securities exercising rights under this Agreement, or any controlling person of any such holder, makes a claim for indemnification pursuant to this Section 7.6, but it is judicially determined (by the entry of a final judgment or decree by a court of competent jurisdiction and the expiration of time to appeal or the denial of the last right of appeal) that such indemnification may not be enforced in such case notwithstanding the fact that this Section 7.5 provides for indemnification in such case, or (ii) contribution under the Securities Act may be required on the part of any such holder or any such controlling person in circumstances for which indemnification is provided under this Section 7.6; then, in each such case, the Company and such Holder will contribute to the aggregate losses, claims, damages or liabilities to which they may be subject as is appropriate to reflect the relative fault of the Company and such Holder in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities, it being understood that the parties acknowledge that the overriding equitable consideration to be given effect in connection with this provision is the ability of one party or the other to correct the statement or omission which resulted in such losses, claims, damages or liabilities, and that it would not be just and equitable if contribution pursuant hereto were to be determined by pro rata allocation or by any other method of allocation which does not take into consideration the foregoing equitable considerations. Notwithstanding the foregoing, no person or entity guilty of fraudulent misrepresentation, within the meaning of Section 11(f) of the Securities Act, shall be entitled to contribution from any person or entity who is not guilty of such fraudulent misrepresentation.

(d)

Notwithstanding any of the foregoing, if, in connection with an underwritten public offering of any Restricted Shares, the Company, the holders of such Restricted Shares and the underwriters enter into an underwriting or purchase agreement relating to such offering which contains provisions covering indemnification among the parties, then the indemnification provision of this Section 7.6 shall be deemed inoperative for purposes of such offering.

7.7

Removal of Securities Legends, Etc. Notwithstanding the foregoing provisions of this Section 7, the restrictions imposed by this Section 7 and Section 4 upon the transferability of any Restricted Securities shall cease and terminate when (a) any such Restricted Shares are sold or otherwise disposed of in accordance with the intended method of disposition by the seller or sellers thereof set forth in a registration statement or such other method that does not require that the securities transferred bear the securities legend set forth in Section 4.8 hereof, including a transfer pursuant to Rule 144 or a successor rule thereof (as amended from time to time), or (b) the holder of Restricted Securities has met the requirements for transfer of such Restricted Securities pursuant to subparagraph (k) of Rule 144 or a successor rule thereof (as amended from time to time) promulgated by the Commission under the Securities Act. Whenever the restrictions imposed by this Section 7 and Section 4 have terminated, a Holder of a certificate for Restricted Shares as to which such restrictions have terminated shall be entitled to receive from the Company, without expense, a new certificate not bearing the restrictive securities legend set forth in Section 4.8 hereof.

7.8

Initial Public Offering. Each Holder, if requested by the Company and the managing underwriter of initial public offering, shall enter into an agreement not to sell or otherwise transfer or dispose of any Restricted Securities or other securities of the Company (excluding securities acquired in the initial public offering or in the public market after such offering) held by such Investor for a period not to exceed 180 days following the effective date of the initial public offering registration statement; provided that:

(a)

all officers, directors and holders of 1% or more of the outstanding shares of Common Stock (on an as-converted basis) of the Company enter into similar agreements;

(b)

the Company use reasonable commercial efforts to ensure that such agreements provide for periodic early releases of the securities subject thereto based upon specified events; and

(c)

the Company use reasonable commercial efforts to ensure that such agreements provide that any discretionary waiver or termination of the restrictions of such agreements by the Company or the managing underwriter and any early release of shares from the restrictions of such agreements shall apply to all persons subject to such agreements on a pro rata basis, based upon the number of Common Stock (on an as-converted basis) held by such persons.

General Rights and Obligations. The rights, obligations and privileges with respect to the Series A Convertible Preferred Stock, no par value per share (the “Series A Preferred Stock”) are governed by and are subject to the Stock Purchase Agreement between Spring Bank Technologies, Inc and Micrologix Biotech, Inc. dated December __, 2003, the terms hereof, applicable provisions of the Chapter 156B of the Massachusetts General Laws (“MGL ch. 156B”), as amended from time to time, and all other laws that are binding on the Company. In addition, the Series A Preferred Stock is subject to the provisions relating thereto in the Company’s Articles of Incorporation, as amended from time to time (“Articles”) and By-laws, as amended from time to time (the "Bylaws").

Dividends. No dividends shall be payable on or in respect to the Series A Preferred Stock.

Liquidation Rights. In the event of any liquidation, dissolution or winding up of the Company, whether voluntary or not, the holder(s) of Series A Preferred Stock shall be entitled to receive, before any amount shall be paid to holders of Common Stock, an amount per share equal to $250.00 (as adjusted for stock splits, combinations or similar events and hereafter referred to as the "Original Issue Price" of the Preferred Shares). If upon the occurrence of a liquidation, dissolution or winding up, the assets and surplus funds distributed to the holder(s) of Series A Preferred Stock shall be insufficient to permit the payment to such holders of the full preferential amount, then the entire assets and surplus funds of the Company legally available for distribution shall be distributed ratably among the holders of the Series A Preferred Stock in proportion to the aggregate amount payable to each of such holders pursuant to the immediately preceding sentence. If upon the occurrence of a liquidation, dissolution or winding up, after the payment to the holders of the Series A Preferred Stock of the preferential amount, assets or surplus funds remain in the Company, the holders of the Company’s Common Stock shall be entitled to receive all such remaining assets and surplus funds.

Voting Rights. Each holder of the Series A Preferred Stock shall have such voting rights as are conferred upon them in MGL ch. 156B, the Articles and the By-laws. The holders of Series A Preferred Stock shall not be entitled to vote for any election of directors of the Company, including elections for the purpose of filling a vacancy, except as may be required by law.

Conversion to Common Stock. The Series A Preferred Stock shall be convertible into Common Stock of the Company as follows:

(a)

Definitions. For purposes of this Section 5 the following definitions shall apply:

(i) "Common Stock Equivalents" means Convertible Securities and rights entitling the Holder thereof to receive directly, or indirectly, additional shares of Common Stock without the payment of any consideration by such Holder for such additional shares of Common Stock or Common Stock Equivalents.

(ii) "Conversion Price" means initially $250 for each share of Series A Preferred Stock, subject to adjustment from time to time pursuant to this Section 5.

(iii) “Conversion Ratio” means the ratio which reflects the number of shares of Common Stock into which one share of Series A Preferred Stock may be converted. The initial Conversion Ratio shall be 1:1 (one share of Common Stock for each share of Series A Preferred Stock), and shall be subject to adjustment from time to time pursuant to Section 5(c)(ii).

(iv) "Convertible Securities" means any indebtedness or shares of stock or other securities convertible into or exchangeable for Common Stock, including without limitation Series A Preferred Stock.

(v) “Issuance Date” means the date upon which the Series A Preferred Stock was first issued to Micrologix.

(vi) “Securities Not Counted for Adjustments” means (A) Common Stock issuable upon conversion of any shares of Series A Preferred Stock; (B) Common Stock issuable pursuant to any securities convertible or exercisable into or exchangeable for Common Stock previously adjusted for pursuant to Section 5(c)(i); (C) options to purchase Common Stock of the Company (including Common Stock issued pursuant to the exercise of such options) issued to directors, officers, employees and consultants of the Company; (D) capital stock of any class issuable upon any subdivision, recombination, split-up or reverse stock split of all outstanding shares of such class of capital stock; (E) Common Stock or securities issued or issuable to banks, lenders or landlords as an incentive or which is required to be issued as a precondition of the loan or lease, as the case may be, provided that the aggregate of such Common Stock or securities does not exceed 5% of the then outstanding shares of the of the capital stock of the Company on an as-converted basis or (F) Common Stock issuable by the Company pursuant to a public offering registered under the Securities Act of 1933, as amended, subsequent to an IPO (as hereinafter defined).

(b) Conversion at Holder’s Option. Each Holder shall have the right (the “Conversion Right”) at any time to convert all or from time to time to convert any part of its Series A Preferred Stock into fully paid shares of Common Stock on the following basis:

(i) Conversion Notice – A Holder may exercise a Holder’s Conversion Right by notice (the “Conversion Notice”) in writing delivered to the Company. The Conversion Notice shall specify the number of Series A Preferred Stock (the “Specified Shares”) the Holder delivering the Conversion Notice wishes to be converted, be signed by the Holder and may be accompanied by the certificates representing the Series A Preferred Stock to be converted.

(ii) Conversion Procedure – Effective as of the date of receipt of a duly signed Conversion Notice and accompanying share certificate or certificates, the Company shall issue and promptly deliver to the Holder tendering the Conversion Notice a certificate representing fully paid and non-assessable shares of Common Stock in the number equal to the Conversion Ratio in effect multiplied by the number of shares of Series A Preferred Stock being converted pursuant to the Conversion Notice. If less than all the shares of Series A Preferred Stock represented by any certificate are converted, the Company shall at its expense promptly issue and promptly deliver a new share certificate to the Holder for the balance of the shares of Series A Preferred Stock not converted.

(c)

Adjustments to Conversion Price and Conversion Ratio. Subject to the other provisions of this Section 5, the Conversion Price and Conversion Ratio in effect from time to time for the Series A Preferred Stock shall be subject to adjustment in certain cases as follows below.

(i) Adjustment for Dilutive Share Issuances. In the event the Company shall at any time after the Issuance Date issue or sell (A) any Common Stock (or shall be deemed to have issued Common Stock pursuant to this Section 5), (B) securities to purchase or acquire Common Stock, (C) or securities convertible or exercisable into or exchangeable for Common Stock, in each case pursuant to a financing or the acquisition of another corporation or entity (or its assets) (collectively a “Dilutive Financing”) then the Conversion Price shall immediately be adjusted to an amount equal to the consideration paid and/or payable for each share of Common Stock issued or issuable pursuant to such Dilutive Financing.

(ii) Stock Splits, Dividends, Distributions and Combinations. In the event the Company shall at any time or from time to time after the Issuance Date fix a record date for the effectuation of a split or subdivision (including reverse splits) of the outstanding shares of Common Stock or the determination of holders of Common Stock entitled to receive any other distribution payable in additional shares of Common Stock or Common Stock Equivalents, then, as of such record date (or the date of such distribution, split or subdivision if no record date is fixed), the Conversion Ratio shall simultaneously be adjusted upon the happening of such event by multiplying the Conversion Ratio in effect immediately prior to such event by the following fraction:

(A) the numerator of which is the number of Common Stock issued and outstanding immediately after completion of the event, and

(B) the denominator of which is the number of Common Stock issued and outstanding immediately prior to the event.

Any such adjustments shall be successive and each resulting new Conversion Ratio shall continue in effect until the next adjustment (if any) is made.

If at any time and from time to time after the Issuance Date, the Common Stock is changed into a different class or classes of shares, whether by reclassification, recapitalization, reorganization, arrangement, amalgamation, or merger, then each Holder shall have the right thereafter to convert its Series A Preferred Stock into the kind and amount of shares and other securities and property receivable upon such change by holders of the number of shares of Common Stock into which the Series A Preferred Stock could have been converted immediately prior to such change.

(iii) Other Events. Upon the occurrence of any event not specifically denominated in this Section 5 as adjusting the Conversion Price of the Series A Preferred Stock or the Conversion Ratio (the “Other Events”) that, in the reasonable exercise of the business judgment of the Board of Directors of the Company requires, on equitable principles, the adjustment of the Conversion Price or Conversion Ratio, such Conversion Price or Conversion Ratio will be equitably adjusted. The Holders of the Series A Preferred Stock may request the Board of Directors of the Company to review adjusting the Conversion Price of the Series A Preferred Stock or the Conversion Ratio for such Other Events.

(iv) Miscellaneous Conversion Matters. The Company shall at all times reserve and keep available out of its authorized but unissued Common Stock the full number of shares of Common Stock deliverable upon conversion of all the then outstanding Series A Preferred Stock and shall, at its own expense, take all such actions and obtain all such permits and orders as may be necessary to enable the Company lawfully to issue such Common Stock upon the conversion of such Series A Preferred Stock.

(v) Excluded Events. Notwithstanding anything in this Section 5 to the contrary, the Conversion Price and the Conversion Ratio of the Series A Preferred Stock shall not be adjusted by virtue of the issuance by the Company of any Securities Not Counted for Adjustments (as defined above).

(vi) Certificate as to Adjustments. Upon the occurrence of each adjustment or readjustment of the Conversion Price of the Series A Preferred Stock or the Conversion Ratio pursuant to this Section 5, the Company, at its expense upon request by any Holder of Series A Preferred Stock, shall compute such adjustment or readjustment in accordance with the terms hereof and prepare and furnish to each Holder of the Series A Preferred Stock a certificate setting forth such adjustment or readjustment and showing in detail the facts upon which such adjustment

or readjustment is based. The Company shall, upon the written request at any time of any Holder of Series A Preferred Stock, furnish or cause to be furnished to such Holder a like certificate setting forth (A) such adjustment and readjustment, (B) the Conversion Price at the time in effect, (C) the Conversion Ratio at the time in effect, and (D) the number of shares of Common Stock and the amount, if any, of other property which at the time would be received upon the conversion of a share of Series A Preferred Stock.

For all purposes of this Section 5(c), the following provisions shall also be applicable:

(A) CASH CONSIDERATION. In the event of the issuance or sale of additional Common Stock or Convertible Securities for cash, the consideration received by the Company therefor shall be deemed to be the amount of cash received by the Company for such securities (or, if such securities are offered by the Company for subscription, the subscription price, or, if such securities are sold to underwriters or dealers for public offering without a subscription offering, the initial public offering price), without deducting therefrom any compensation or discount paid or allowed to underwriters or dealers or others performing similar services or for any expenses incurred in connection therewith.

(B) NON-CASH CONSIDERATION. In the event of the issuance (otherwise than upon conversion or exchange of Convertible Securities) or sale of additional Common Stock or Convertible Securities for a consideration other than cash or a consideration a part of which shall be other than cash, the fair value of such consideration as determined by the Board of Directors of the Company in the good faith exercise of its business judgment, irrespective of the accounting treatment thereof, shall be deemed to be the value, for purposes of this Section 5, of the consideration other than cash received by the Company for such securities.

(C) CONVERTIBLE SECURITIES. In the event the Company shall in any manner issue any Convertible Securities, the total maximum number of shares of Common Stock issuable upon conversion or exchange of the total maximum amount of such Convertible Securities at the time such Convertible Securities first become convertible or exchangeable shall (as of the date of issue or sale of Convertible Securities) be deemed to be issued and to be outstanding for the purpose of Section 5(c)(i) and to have been issued for the sum of the amount (if any) paid for such Convertible Securities and the amount (if any) payable upon conversion or exchange of such Convertible Securities at the time such Convertible Securities first become convertible or exchangeable: provided that, no further adjustment of the Conversion Price of the Series A Preferred Stock shall be made upon the actual issuance of any such Common Stock or Convertible Securities or upon the conversion or exchange of any such Convertible Securities.

(d)

Resolution of Calculation and Adjustment Questions. If at any such time a question arises with respect to adjustments or calculations made under this Section 5, such questions shall be determined by the accountants or auditors of the Company, or, if requested in writing by the Holder, by a single arbitrator pursuant to the Commercial Arbitration Rules of the American Arbitration Association, including the Supplementary Procedures for Large Complex Disputes. The determination of such arbitrator shall be binding upon the Company and the Holder. The arbitration shall take place in New York, New York. The arbitrator shall apply the laws of the State of New York, without regard to its conflicts of laws provisions.

(e)

No Impairment. The Company will not, by amendment of the Articles or through any reorganization, recapitalization, transfer or assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed by the Company under this Section 5, but will at all times in good faith assist in the carrying out of all the provisions of this Section 5 and in the taking of all such action as may be necessary or appropriate in order to protect the conversion and redemption rights of the Holders of Series A Preferred Stock against impairment.

(f)

No Fractional Shares. No fractional shares shall be issued upon conversion of shares of Series A Preferred Stock and the number of shares of Common Stock to be issued shall be rounded to the next smaller whole share. Whether or not fractional shares are issuable upon such conversion shall be determined on the basis of the total number of shares of Series A Preferred Stock the Holder is at the time converting into Common Stock and the number of shares of Common Stock issuable upon such aggregate conversion. The value of any fractional share issuable upon conversion shall be paid in cash by the Company.

(g)

Automatic Conversion. Immediately upon the effectiveness of the Company's initial registration statement on Form S-1 (the “IPO Effective Date”) pursuant to which Common Stock is sold to the public by the Company (or selling stockholders, if any) in a public offering registered under the Securities Act of 1933, as amended (an “IPO”), each share of Series A Preferred Stock then outstanding (other than Series A Preferred Stock which are being redeemed pursuant to Section 6 below) shall, at the option of the Holder, be converted into shares of Common Stock at the Conversion Ratio for such Series A Preferred Stock then in effect. On and after said conversion date, notwithstanding that any certificates for the shares of Series A Preferred Stock shall not have been surrendered for conversion, the shares of Series A Preferred Stock evidenced thereby shall be deemed to be no longer outstanding, and all rights with respect thereto shall forthwith cease and terminate, except only the rights of the Holder (i) to receive the shares of Common Stock to which such Holder shall be entitled upon conversion thereof and (ii) to receive the amount of cash payable in respect of any fractional share of Common Stock to which such Holder shall be entitled. In the event that any Holder of Series A Preferred Stock presents such Holder's certificate therefor for surrender to the Company or its transfer agent upon such conversion, a certificate for the number of shares of Common Stock into which the shares of Series A Preferred Stock surrendered were convertible on such conversion date promptly will be issued and delivered to such Holder.

Redemption.

(a)

Redemption Upon an IPO. The Company shall give notice to the Holders of the Series A Preferred Stock of its intent to effect an IPO (the “IPO Notice”). Each such Holder shall then have the right to request the Company to redeem all or any portion of such Holder’s Preferred Shares. Such Holder shall make such request, stating the number of Preferred Shares such Holder desires to redeem, by delivering a written notice signed by the Holder (the “Redemption Notice”) within twenty (20) days of the date of the IPO Notice. The Company shall redeem the Preferred Shares so requested at a price equal to $250.00 per Preferred Share being redeemed (the “Redemption Price”). Such redemption shall be deemed to have occurred on the IPO Effective Date. The Redemption Price shall be payable by the Company on any date

(the “Redemption Payment Date”) not later than 30 days after the conclusion of the IPO. On and after the IPO Effective Date, any rights of any Holder with respect to those Preferred Shares being redeemed by the Company, shall cease and terminate, except for the right to receive the Redemption Price for such Preferred Shares, and such Preferred Shares shall no longer be deemed to be outstanding, whether or not the certificates representing such Preferred Shares shall have been received by the Company.

(b)

Expiry Redemption. So long as the Series A Preferred Stock has not been converted to Common Stock pursuant to Section 5 above or redeemed pursuant to Section 6(a) above, on December 15, 2011 and on December 15 of each year thereafter (each such date being referred to as the “Series A Preferred Share Expiry Date”), each Holder of Series A Preferred Stock shall then have the right to request the Company to redeem all or any portion of such Holder’s Series A Preferred Shares. Such Holder shall make such request, stating the number of Series A Preferred Shares such Holder desires to redeem, by delivering a notice (the “Expiry Redemption Notice”) to the Company within twenty (20) days of the date of the Series A Preferred Share Expiry Date. The Company shall redeem the Series A Preferred Shares so requested at the Redemption Price. The Redemption Price shall be payable by the Company not later than 30 days after receipt of the Expiry Redemption Notice. On and after the Series A Preferred Share Expiry Date, any rights of any Holder with respect to those shares of Series A Preferred Stock being redeemed by the Company, shall cease and terminate, except for the right to receive the Redemption Price for such shares , and such shares of Series A Preferred Stock shall no longer be deemed to be outstanding, whether or not the certificates representing such shares of Series A Preferred Stock shall have been received by the Company.

(c)

Redemption Subject to Applicable Law. If the Company is not permitted by insolvency provisions or other provisions of applicable law to redeem all or any portion of the Series A Preferred Shares required to be redeemed hereunder (if not otherwise converted, as the case may be), the Company shall, pursuant to the terms of this Section 6, redeem only the maximum number of Series A Preferred Shares (as determined in good faith by the Board of Directors of the Company) it is then permitted to redeem and shall make any payment to the holder of the Series A Preferred Shares required by this Agreement.

Make Whole Obligation. If, upon the Company becoming obligated to redeem or convert any shares of the Series A Preferred Stock pursuant to Section 5 or 6 hereof, the Company is not permitted by applicable law to redeem or convert any portion of the shares the Series A Preferred Stock required to be redeemed (if not otherwise converted as the case may be) or converted, the holders of such shares shall be entitled to retain the shares which have not been permitted to be redeemed or converted, as the case may be.

Transfer. The shares of Series A Preferred Stock shall be freely transferable by the holders thereof except as set forth in the Stock Purchase Agreement, the By-Laws, the Articles, and any other agreement entered into by the holder of such shares which may place restrictions on transfer thereof.
