AGREEMENT AND PLAN OF MERGER

This AGREEMENT AND PLAN OF MERGER (this “Agreement”) is made as of October 5, 2006, by and among VALENTIS, INC., a Delaware corporation (“Parent”), VALENTIS HOLDINGS, INC., a Delaware corporation and direct wholly-owned subsidiary of Parent (“Merger Sub”), and URIGEN N.A., INC., a Delaware corporation (“Urigen,” formerly known as “Urigen Canada”). Certain terms are used herein as defined below in Article 16 or elsewhere in the Agreement.

WHEREAS, Urigen Holdings, Inc. (“Urigen Canada”), a corporation organized and existing under the laws of British Columbia, has been re-domesticated as a Delaware corporation (the “Re-domestication”) under the name “Urigen N.A., Inc.” by filing a Certificate of Domestication with the Secretary of State of Delaware pursuant to Section 388 of the Delaware General Corporation Law (“DGCL”);

WHEREAS, the Boards of Directors of each of Parent, Merger Sub, and Urigen believe that the merger of Merger Sub into Urigen (the “Merger”) would be in the best interest of and beneficial to their respective corporations and stockholders; and

WHEREAS, the parties hereto intend that the Merger shall qualify for U.S. federal income tax purposes as a reorganization within the meaning of Section 368(a) of the U.S. Internal Revenue Code of 1986, as amended (together with the rules and regulations promulgated thereunder, the “Code”).

NOW, THEREFORE, in consideration of the mutual covenants and agreements hereinafter set forth and of other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties hereto agree that Merger Sub shall be merged with and into Urigen and Urigen, as the surviving corporation, shall become a wholly-owned subsidiary of Parent upon the terms and subject to the conditions set forth in this Agreement.

The Merger shall become effective on the date and at the time of the acceptance for record of the Certificate of Merger by the Secretary of State of Delaware in accordance with the DGCL, or at such time specified in the Certificate of Merger (the “Effective Time”).

(b)        Urigen shall continue as the Surviving Corporation, organized under the laws of the State of Delaware, the authorized capital stock of which shall be as set forth in the Certificate of Merger;

(c)        the Certificate of Incorporation and Bylaws of Urigen shall be amended at and as of the Effective Time as set forth in the Certificate of Merger, and as so amended shall be the Certificate of Incorporation and Bylaws of the Surviving Corporation;

ARTICLE 2.   PROCEDURES; FRACTIONAL SHARES; ADJUSTMENTS, ETC.

2.1        Certificates of Urigen Stock.   Certificates that represent shares of Urigen Stock that are outstanding immediately prior to the Effective Time (each a “Certificate”) and are converted into shares of Parent Stock pursuant to Section 1.2(e) shall, after the Effective Time, be deemed to represent the shares of the Parent Stock into which such shares have been converted and shall be exchangeable by the holders thereof in the manner provided in Section 2.2 and Section 2.3 below for new certificates representing the shares of Parent Stock into which such shares of Urigen Stock have been converted.

2.2        Replacement of Certificates.   As promptly as practicable after the Effective Time, Parent or its transfer agent for Parent Stock shall send to each holder of record of shares of Urigen Stock (other than with respect to any such shares held directly or indirectly by Parent, Urigen or dissenting stockholders referred to in Section 2.11 below) outstanding immediately prior to the Effective Time (the “Urigen Stockholders”), transmittal materials for use in exchanging the Certificates for such shares for certificates for the shares of Parent Stock into which such shares of Urigen Stock have been converted pursuant to Section 1.2(e). Upon surrender of a Certificate to Parent (or the transfer agent for Parent Stock), together with a duly executed letter of transmittal and any other required documents, such Certificate shall be cancelled and exchanged for a certificate for the number of shares of Parent Stock to which such holder is entitled in accordance with the provisions and procedures set forth in Section 1.2(e) and this Article 2 (or returned to the presenting Person, if the shares of Urigen Stock formerly represented by such Certificate are held of record by a former Urigen Stockholder who has duly exercised the appraisal rights described in Section 2.4 and Section 2.11 below).

2.3        Dividends and Distribution.   Any Urigen Stockholder holding unsurrendered Certificates (other than Urigen Stockholders who have duly exercised the appraisal rights described in Section 2.4 and Section 2.11 below who shall not be entitled to the dividends or other distributions described herein) shall not receive any dividend or other distribution payable after the Effective Time with respect to Parent Stock

2

---

until such Urigen Stockholder surrenders such Certificate, at which time such Urigen Stockholder shall receive all dividends and distributions, without interest thereon, otherwise payable after the Merger (if any) but withheld from such Urigen Stockholder pursuant hereto.

2.4        Rights of Holders of Urigen Stock.   After the Effective Time, holders of Urigen Stock shall cease to be, and shall have no rights as, stockholders of Urigen, other than (i) to receive shares of Parent Stock into which such shares have been converted pursuant to the provisions hereof, and (ii) any rights afforded to any such holder who has demanded appraisal rights in compliance with all provisions of the laws of the State of Delaware concerning the right of such holder to dissent from the Merger and demand appraisal of such shares of Urigen Stock.

2.5        No Further Transfer of Shares.   After the Effective Time, there shall be no transfers of Urigen Stock that were outstanding immediately prior to the Effective Time on the stock transfer book of the Surviving Corporation. If, after the Effective Time, Certificates are presented to the Surviving Corporation for transfer, they shall be cancelled and exchanged for Parent Stock as provided in Section 1.2(e) and Section 2.2 hereof.

2.6        No Liability for Abandoned Property.   Neither Parent nor Urigen nor any other Person shall be liable to any former holder of shares of Urigen Stock for any shares or any dividends or distributions with respect thereto properly delivered to a public official pursuant to applicable abandoned property, escheat or similar Laws. Any Merger Consideration remaining unclaimed two years after the Effective Time (or such earlier date immediately prior to such time as such amounts would otherwise escheat to or become property of any governmental entity) shall, to the extent permitted by applicable Law, become the property of Parent free and clear of any claims or interest of any Person previously entitled thereto.

2.7        Lost, Stolen or Destroyed Certificates.   If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and, if required by Parent in its discretion and as a condition precedent to the issuance thereof, the posting by such Person of a bond in such reasonable amount as Parent may direct as indemnity against any claim that may be made against any of Parent, the Surviving Corporation and the transfer agent for Parent Stock with respect to such Certificate, Parent or its transfer agent will deliver in exchange for such lost, stolen or destroyed Certificate a certificate for the applicable shares of Parent Stock deliverable in respect thereof pursuant to Section 1.2(e) and this Article 2, any cash issuable (if any) in lieu of fractional Parent Stock, and unpaid dividends and distributions in respect of or on Parent Stock deliverable in respect thereof, pursuant to this Agreement.

2.8        Transfer of Certificates.   If any certificate representing shares of Parent Stock is to be issued in a name other than that in which the Certificate surrendered in exchange therefore is registered, it shall be a condition to the issuance thereof that the Certificate so surrendered shall be properly endorsed (or accompanied by an appropriate instrument of transfer) and otherwise in proper form for transfer (including a medallion guarantee as to the signature of the transferor if so requested by Parent), and that the Person requesting such exchange shall pay to Parent in advance any transfer or other taxes required by reason of the issuance of a certificate representing shares of Parent Stock in any name other than that of the registered holder of the Certificate surrendered, or required for any other reason, or shall establish to the satisfaction of Parent that such Tax has been paid or is not payable.

2.9        No Fractional Shares.   No fractional share of Parent Stock shall be issued in the Merger. Each Urigen Stockholder who would otherwise be entitled to receive a fractional share of Parent Stock shall receive a cash payment in lieu thereof (without interest) in an amount equal to such fractional share of Parent Stock multiplied by weighted 30-day average price of Parent Stock as quoted on the Nasdaq Capital Market calculated for the 30-day period immediately prior to the first public announcement of the

3

---

transactions contemplated by this Agreement. No such holder shall be entitled to dividends, voting rights or any other rights as a stockholder in respect of any fractional shares of Parent Stock.

2.10     Exercise of Options, Warrants and Conversion of Notes and Preferred Stock.   On or before the Effective Time, all outstanding stock options, warrants and other rights to purchase or acquire capital stock of Urigen shall be exercised or exchanged as provided in Section 7.8 hereof and all outstanding securities exchangeable for or convertible into capital stock of Urigen, including, without limitation, the Urigen Preferred Stock, shall be exchanged and/or converted into capital stock of Urigen. Immediately prior to the Effective Time, the outstanding capital stock of Urigen shall consist only of Urigen Common Stock. For all purposes of this Agreement, the shares of the capital stock of Urigen issued upon exercise or in exchange for such outstanding stock options, warrants and other rights or upon conversion of any other securities exchangeable for or convertible into the capital stock of Urigen shall be deemed the capital stock of Urigen and the recipients thereof shall be deemed to be Urigen Stockholders.

2.11     Dissenting Shares.   Notwithstanding Section 1.2(e) and Article 2 hereof, the shares of Urigen Stock that are issued and outstanding immediately prior to the Effective Time and that are held by Urigen Stockholders who did not vote in favor of the Merger and who comply with all of the relevant provisions of Section 262 of DGCL (the “Dissenting Shares”) shall not be converted into Parent Stock, unless and until such Urigen Stockholders shall have waived in writing or failed to perfect or shall have effectively withdrawn or lost their rights to appraisal under Section 262 of DGCL; and any such Urigen Stockholder shall have only such rights in respect of the Dissenting Shares owned by them as are provided by DGCL. If any such Urigen Stockholder shall have waived in writing or failed to perfect or shall have effectively withdrawn or lost such right, such Urigen Stockholder’s Dissenting Shares shall thereupon be deemed to have been converted into and to have become exchangeable, as of the Effective Time, for Parent Stock without any interest thereon, pursuant to the terms of Section 1.2(e) and Article 2. Urigen will promptly comply with its obligations under Section 262 of the DGCL and will give Parent prompt notice of any demands and withdrawals of such demands received by Urigen for appraisals of Dissenting Shares.

2.12     Intentionally Omitted.

2.13     Extraordinary Adjustments.   If subsequent to the date hereof but prior to the Effective Time, Urigen changes the number of shares of Urigen Stock, or Parent changes the number of shares of Parent Stock, issued and outstanding as a result of a stock split, stock combination, dividend of stock or other securities (or a record date within such period with respect to such a dividend), recapitalization, redenomination of share capital or other similar transaction (including, without limitation, the “Reverse Split” as defined below, collectively, the “Stock Transactions”), the Conversion Number and other items dependent thereon shall be appropriately adjusted to provide to the holders of Urigen Stock the same economic effect and percentage ownership of Parent Stock as contemplated by this Agreement prior to such Stock Transaction. Prior to the Closing Date, and subject to the approval of Parent’s stockholders, Parent shall effect a reverse stock split of its capital stock in a range to be determined by Parent’s Board of Directors (after consultation with Urigen) for the purpose of ensuring Parent’s compliance with the listing requirements of the Nasdaq Capital Market (the “Reverse Split”).

2.14     Minimum Liquidity and Net Worth; Purchase Price Adjustment.

(a)        Within five (5) Business Days after the execution of this Agreement and thereafter not later than the twentieth (20th) Business Day of each month after the month in which this Agreement is signed, Parent shall deliver to Urigen a calculation of (1) Parent’s consolidated net worth, including a calculation of the net assets and a calculation of the net liabilities of Parent (“Net Worth”), and (2) a calculation of Parent’s cash and cash equivalents with immediate maturity and convertible to cash net of any penalty (the “Cash Balance”) (such calculations collectively, the “Calculations” and such Calculations as provided below the “Closing Calculations”). Not later than five (5) Business Days prior to the scheduled Closing Date, Parent shall deliver Closing

4

---

Calculations reflecting Net Worth as of such date minus all known or expected changes through the scheduled Closing Date (the “Closing Net Worth”), and Cash Balance as of such date minus all known or expected changes through the scheduled Closing Date (the “Closing Cash Balance”). Except as expressly contemplated by this Agreement, the calculation of Closing Net Worth shall be made in accordance with generally accepted accounting principles in the United States (“U.S. GAAP”).

(b)        At the Closing, the Cash Balance determined pursuant to Section 2.14(a) above shall be compared to a benchmark Cash Balance of $1,000,000, with any difference between actual Cash Balance and such benchmark Cash Balance being referred to herein as the “Cash Balance Difference.” If the Cash Balance is a deficit amount, i.e., below $1,000,000, then the Cash Balance Difference shall be expressed as a positive number (the “Liquidity Shortfall”). If the Cash Balance is a zero or a positive amount, the then the Cash Balance Difference shall be expressed as a negative number.

(c)        At the Closing, the Net Worth determined pursuant to Section 2.14(a) above shall be compared to a benchmark Net Worth of $1,000,000, with any difference between actual Net Worth and such benchmark Net Worth being referred to herein as the “Net Worth Difference.” If Net Worth is a deficit amount, i.e., below $1,000,000, then the Net Worth Difference shall be expressed as a positive number (the “Net Worth Shortfall”). If Net Worth is a zero or a positive amount, the then Net Worth Difference shall be expressed as a negative number.

(d)        If, based on the Closing Cash Balance or the Closing Net Worth, either the Liquidity Shortfall or the Net Worth Shortfall is more than or equal to $200,000, then Urigen shall have the right to terminate this Agreement (which right shall be exercised in no event later than three (3) Business Days after the final determination of the Liquidity Shortfall and the Net Worth Shortfall). By way of clarification and for the avoidance of doubt, Urigen shall not receive any Termination Fee or reimbursement of Expenses, nor shall Urigen be obligated to pay any Termination Fee to, or reimburse any Expenses of, Parent or Merger Sub, if this Agreement is terminated as a result of any Liquidity Shortfall or any Net Worth Shortfall pursuant to this Section 2.14(d). In the event of any Liquidity Shortfall or any Net Worth Shortfall, pursuant to which this Agreement is not terminated, the Merger Consideration will be adjusted by an increase in the number of shares issuable to the holders of Urigen’s Stock by an aggregate amount equal to the amount of the Liquidity Shortfall or Net Worth Shortfall (whichever is greater) divided by the weighted 30-day average price of Parent Stock as quoted on the Nasdaq Capital Market calculated for the 30-day period immediately prior to the first public announcement of the transactions contemplated by this Agreement (the “Shortfall Shares”) and such Shortfall Shares shall be issued pro rata to the Urigen Stockholders (the “Closing Adjustment”). No fractional Shortfall Shares shall be issued and any fractional Shortfall Share amount to which the holders of Urigen’s Stock would be entitled to as a result of such Closing Adjustment shall instead be paid in cash (without interest) in a manner consistent with Section 2.9 of this Agreement.

(e)        Prior to Closing, contemporaneously with each of the Calculations, Parent shall (i) provide Urigen and Urigen’s authorized representatives with full access at all reasonable times, and in a manner so as not to interfere with the normal business operations of Parent, to all relevant books, records, work papers, information and employees of such Persons, and (ii) cooperate fully with Urigen and Urigen’s authorized Representatives, in each case as is necessary or useful for the preparation, calculation and review of the Calculations, or for the resolution of any dispute between the parties relating thereto.

5

---

(f)         The Closing Calculations may be reviewed, at the option and expense of Urigen, by ▇▇▇▇▇ ▇▇▇▇▇▇▇▇, LLP, independent registered public accounting firm for Urigen (“Urigen’s Auditor”), who will be afforded full access to all books and records of Parent and its subsidiaries.

(g)        Unless Urigen disputes the Closing Calculations pursuant to this Section 2.14(g) within two (2) Business Days after receipt from Parent, the Closing Calculations delivered by Parent to Urigen shall be final, binding and conclusive on Urigen and Parent. Urigen may dispute any item shown on the Closing Net Worth or Closing Cash Balance Calculations by sending written notice (a “Dispute Notice”) to Parent within one (1) day prior to the scheduled Closing. The Dispute Notice shall identify each disputed item with respect to the Closing Calculations, as applicable, specify, to the extent practicable, the amount of such dispute and set forth in general terms the basis for such dispute. In the event of such a dispute, the Closing shall be delayed and, subject to Urigen’s termination rights in Section 2.14(d), Urigen and Parent shall attempt in good faith to resolve their differences, and any resolution by them as to any disputed items shall be final, binding, and conclusive on Urigen and Parent. If Urigen and Parent are unable to reach a resolution of all of their differences within ten (10) days after Urigen delivers the Dispute Notice to Parent, then Urigen and Parent shall promptly submit any remaining disputed items to PricewaterhouseCoopers or any other accounting firm mutually acceptable to Urigen and Parent (the “Independent Accounting Firm”). If any remaining disputed items are submitted to the Independent Accounting Firm for resolution, (i) each party will furnish to the Independent Accounting Firm such work papers and other documents and information relating to the remaining disputed items as the Independent Accounting Firm may request and are available to such party, and each party will be afforded the opportunity to present to the Independent Accounting Firm any material relating to the disputed items and to discuss the resolution of the disputed items with the Independent Accounting Firm; (ii) each party will use its good faith best efforts to work with the other parties and the Independent Accounting Firm to resolve the disputed items within twenty (20) days after the submission of the disputed items to the Independent Accounting Firm; (iii) the determination by the Independent Accounting Firm, as set forth in a written notice to Urigen and Parent, shall be final, binding and conclusive on Urigen and Parent, and (iv) the fees and disbursements of the Independent Accounting Firm shall be allocated between Urigen and Parent so that Urigen pays for the percentage of such fees and disbursements equal to the ratio that the amount of the disputed items submitted to the Independent Accounting Firm that is unsuccessfully disputed by Urigen (as finally determined by the Independent Accounting Firm) bears to the total amount of all disputed items submitted to the Independent Accounting Firm, and Parent shall pay the balance of such fees and disbursements; provided, however, that if, following such resolution, Urigen would be entitled to terminate this Agreement (and prior to such resolution Urigen did not have such right), Parent shall pay such fees and disbursements in their entirety if Urigen elects to terminate this Agreement; otherwise, such fees and disbursements for which Parent is responsible shall be treated as a reduction to the Cash Balance and such fees and disbursements for which Urigen is responsible shall be treated as an addition to the Cash Balance, in each case, for purposes of calculation of the Closing Adjustment.

(h)        The Closing Calculations shall be deemed to be final, binding and conclusive on Urigen and Parent upon the earliest of (i) the failure of Urigen to notify Parent of a dispute by the deadline set forth in Section 2.14 (g) after the receipt of the Closing Calculations; (ii) the resolution of all disputes by Urigen and Parent; and (iii) the resolution of all disputes by the Independent Accounting Firm.

6

(i)         Urigen and Parent shall use commercially reasonable efforts to cause the Independent Accounting Firm to render its decision as soon as is reasonably practicable, including, without limitation, prompt compliance with all reasonable requests by the Independent Accounting Firm for information, papers, books, records and the like; provided that Urigen and Parent agree that the purpose of retention of the Independent Accounting Firm shall not include the conduct of its own independent audit of the Closing Calculations, but rather shall be limited to resolving the issues presented to it and matters related thereto. All decisions of the Independent Accounting Firm with respect to the Closing Calculations shall be final and binding upon both Urigen and Parent.

2.15     Withholding.   Parent or its agent shall be entitled to deduct and withhold from any consideration payable or otherwise deliverable pursuant to this Agreement to any holder or former holder of Urigen Stock such amounts as may be required to be deducted or withheld therefrom under this Agreement, under the Code or, any provision of state, local or foreign Tax Law, or under any other applicable Law. To the extent such amounts are so deducted or withheld, such amounts shall be treated for all purposes under this Agreement as having been paid to the person to whom such amounts would otherwise have been paid.

Urigen hereby represents and warrants to Parent and Merger Sub as follows:

3.1        Incorporation; Authority.   Urigen is a corporation duly organized, validly existing and in good standing under the laws of the State of Delaware and has all requisite corporate power and authority to own or lease and operate its properties and to carry on its business as now conducted in all material respects. Urigen has supplied to Parent complete and correct copies of its Certificate of Incorporation and Bylaws and all amendments thereto. Urigen is duly qualified and in good standing as a foreign corporation in each jurisdiction in which the character of the properties owned or leased or the nature of the activities conducted by it makes such qualification necessary, unless the failure to so qualify does not have a material adverse effect on the business, assets or financial condition of Urigen. Urigen has been validly discontinued as a corporation under the Business Corporations Act (British Columbia) and has complied with all requirements of such statute in connection therewith, including but not limited to, notices to stockholders with respect to the Re-domestication and the procedures for exercising dissent or similar rights.

3.2        Corporate Power; Binding Effect.   Subject to Urigen Stockholders’ approval, Urigen has all requisite corporate power and authority to enter into this Agreement and the Certificate of Merger, and to perform all of its agreements and obligations under this Agreement and the Certificate of Merger in accordance with their respective terms.

Upon execution and delivery by Urigen of the Certificate of Merger on the Closing Date, the Certificate of Merger will have been duly authorized, executed and delivered by, and constitute the legal, valid and binding obligation of, Urigen subject to the Enforcement Exceptions. Neither the execution, delivery or performance by Urigen of this Agreement nor of the Certificate of Merger in accordance with their respective terms will result in any violation of or default or creation of any lien under, or the acceleration or vesting or modification of any right or obligation under, or in any conflict with, Urigen’s Certificate of

7

Incorporation or Bylaws or of any agreement, instrument, judgment, decree, order, statute, rule or regulation binding on or applicable to Urigen, except where any of the foregoing would not have a material adverse effect on the business, assets or financial condition of Urigen. Urigen has taken all action necessary to exempt the transactions contemplated by this Agreement from the operation of any applicable “fair price,” “moratorium,” “control share acquisition” or other similar anti-takeover statute or regulation enacted under the state or federal laws of the United States.

Except as set forth in Schedule 3.4, Urigen is neither a party to nor is bound by any outstanding subscriptions, options, warrants, calls, commitments or agreements of any character calling for Urigen to issue, deliver or sell, or cause to be issued, delivered or sold any shares of Urigen Stock or any other equity security of Urigen or any securities convertible into, exchangeable for or representing the right to subscribe for, purchase or otherwise receive any shares of Urigen Stock or any other equity security of Urigen or obligating Urigen to grant, extend or enter into any such subscriptions, options, warrants, calls, commitments or agreements.
