TRANSFER AGREEMENT AND PLAN OF REORGANIZATION

Exhibit 2.3

AND PLAN OF REORGANIZATION

THIS TRANSFER AGREEMENT AND PLAN OF REORGANIZATION (this “Agreement”) is made as of May 31, 2013, by and between GIGAMON SYSTEMS LLC, a California limited liability company (“Transferor”), and Gigamon Inc., a Delaware corporation (“Acquirer”).

Recitals

A. Transferor has elected to be treated as a corporation for federal and state income tax purposes, and holds shares of Acquirer’s common stock, par value $0.0001 per share (“Acquirer’s Common Stock”).

B. Acquirer is the successor of Gigamon LLC, a Delaware limited liability company.

C. Transferor desires to transfer to Acquirer, and Acquirer desires to receive from Transferor, those assets of Transferor listed on Schedule A hereto (collectively, the “Assets”), for the consideration and on the terms set forth in this Agreement, including the issuance by Acquirer to Transferor of 16,851,635 shares of Acquirer’s Common Stock (the “Consideration”). Transferor represents that the Assets constitute substantially all of the assets of Transferor.

D. Certain employees and service providers of Acquirer were originally employed by Transferor, prior to January 2, 2009, and were granted options to acquire shares representing membership interests in Transferor (each a “Transferor Option” and collectively the “Transferor Options”). Acquirer desires to substitute options to purchase Acquirer’s Common Stock for all Transferor Options, as listed on Schedule B hereto, and ensure that each Transferor Option, so substituted by the Acquirer under this Agreement, shall continue to have, and be subject to, the substantially equivalent same terms and conditions (including, if applicable, the vesting arrangements and other terms and conditions set forth in the applicable stock option agreement, with appropriate adjustments to the exercise price and the number of shares of Acquirer’s Common Stock subject to such substituted Transferor Options) as are in effect immediately prior to the Closing Date, except as set forth in Section 2.2 below. The transfer of the Assets contemplated by Recital C above and the substitution of Transferor Options contemplated hereby are sometimes referred to herein collectively as the “Contemplated Transaction.”

E. Immediately after the consummation of the Contemplated Transaction, Transferor will dissolve and, pursuant to a plan of complete liquidation (the “Liquidation Plan”) which will be completed as soon as practicable but in no event later than 12 months after the date of this Agreement, distribute to Transferor’s equityholders their proportionate interests, based on the outstanding capitalization of Transferor, in the Consideration (the “Consideration Distribution”). Equityholders of outstanding shares of Transferor shall be entitled to receive Acquirer’s Common Stock from Transferor as part of such Consideration Distribution. In connection with the Consideration Distribution, cash will be distributed to Transferor’s equityholders in lieu of fractional

shares of the shares of Acquirer’s Common Stock constituting the Consideration. Such fractional shares will be purchased from Transferor by Acquirer.

F. The Acquirer has filed a Registration Statement on Form S-1 (File No. 333-182662) (the “Registration Statement”) with the Securities and Exchange Commission (the “SEC”) and has filed an application with the New York Stock Exchange (the “NYSE”) to have the Acquirer’s Common Stock publicly traded on the NYSE.

G. Transferor desires to enter into this Agreement and consummate the Contemplated Transaction and the Consideration Distribution in order to (i) provide its equityholders and optionees with shares of Acquirer’s Common Stock and/or options to purchase shares of Acquirer’s Common Stock, as applicable, in cancellation and satisfaction of shares Transferor pursuant to the Liquidation Plan or the substitution of options to purchase shares of Transferor with options to purchase shares of Acquirer’s Common Stock, (ii) resolve potential differences and disputes among Transferor’s equityholders relating to Transferor’s strategic direction and dividend policy, (iii) eliminate Transferor’s control over decisions relating to the sale of substantially all of Transferor’s shares of Acquirer’s Common Stock, and (iv) other business reasons.

H. Acquirer desires to enter into this Agreement and consummate the Contemplated Transaction in order to (i) reduce uncertainty as to the market value of shares of Acquirer’s Common Stock caused by the ownership of such shares in an entity which is not an institutional investor, (ii) increase the number of beneficial holders of Acquirer’s Common Stock and, thereby, increase the potential liquidity of shares of Acquirer’s Common Stock, and (iii) other business reasons.

I. For federal income tax purposes, it is intended that the Contemplated Transaction qualify as a “reorganization” within the meaning of Section 368(a)(1)(C) and (D) of the Internal Revenue Code of 1986, as amended (a “Reorganization”).

Between the date of this Agreement and the Closing Date, Transferor and Acquirer will promptly notify one another in writing if such party becomes aware of any fact or condition that causes or constitutes a Breach of any of such party’s representations and warranties as of the date of this Agreement, or if such party becomes aware of the occurrence after the date of this Agreement of any fact or condition that would cause or constitute a Breach of any such representation or warranty had such representation or warranty been made as of the time of occurrence or discovery of such fact or condition. During the same period, Transferor and Acquirer will promptly notify one another of the occurrence of any Breach of any covenant of such party, under this Agreement or of the occurrence of any event that may make the satisfaction of the conditions in Articles VI and VII impossible or unlikely.

5.4 Information Statement.

Acquirer shall be responsible for providing the Acquirer Information to Transferor.

(b) Subject to Acquirer’s review and approval, Transferor will cause the Information Statement, at the time it is disseminated to Transferor’s equityholders, to comply as to form in all material respects with the applicable provisions of the Securities Act and the Exchange Act; provided, however, that Transferor shall have no responsibility with respect to the accuracy or completeness of the Acquirer Information.

(c) Each of Acquirer, solely with respect to the Acquirer Information, and Transferor, with respect to all other information in the Information Statement, agrees that it will use its Commercially Reasonable Efforts to ensure that the Information Statement (at the time it is

-13-

disseminated to Transferor’s equityholders and on the Closing Date) will not contain 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. If, at any time prior to the Closing Date, any event with respect to Transferor or Acquirer, or with respect to information included in the Information Statement, occurs and such event is required to be described in an amendment or supplement to the Information Statement, Transferor or Acquirer will promptly notify the other party of such occurrence and will prepare (with the cooperation of the other party) such amendment or supplement and disseminate such amendment or supplement to Transferor’s equityholders.

5.6 No Assumption of Liabilities or Obligations. Acquirer does not assume or agree to pay, satisfy, discharge or perform, and shall not be deemed by virtue of the execution and delivery of this Agreement, or of any instrument, paper or document delivered by it pursuant to this Agreement, or as a result of the consummation of the transactions contemplated by this Agreement, to have assumed, or to have agreed to pay, satisfy, discharge or perform, any liability, obligation or indebtedness of Transferor including liabilities and obligations with respect to Taxes of Transferor (including any Taxes of Transferor of any kind attributable to the Consideration Distribution or the Contemplated Transaction) and liabilities and obligations with respect to representations and warranties previously made by Transferor to any person. It is understood and agreed that Transferor shall retain all liability for, and Acquirer shall not assume or have any obligation with respect to, any liability, obligation or indebtedness of Transferor including liabilities and obligations with respect to Taxes of Transferor (including any Taxes of Transferor of any kind attributable to the Consideration Distribution or the Contemplated Transaction) and liabilities and obligations with respect to representations and warranties previously made by Transferor to any person. As provided in Section 9.2, Transferor shall indemnify Acquirer with respect to (a) such liabilities, obligations and indebtedness and (b) Proceedings and claims resulting from representations and warranties previously made by Transferor to any person.

5.7 Restrictive Legend. Transferor acknowledges that the following restrictive legend will be set forth on the certificates evidencing shares of Acquirer’s Common Stock which are issued pursuant to subsection (b) of Section 2.4 and subsection (b) of Section 2.5:

THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933. THEY MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED OR HYPOTHECATED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT UNDER SAID ACT OR OPINION OF COUNSEL SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED.

5.9 Matters Regarding Transferor’s Equityholders.

(a) Transferor has heretofore provided to Acquirer copies of all questionnaires completed by Transferor’s equityholders in anticipation of the transactions contemplated by this Agreement. The parties acknowledge that the Information Statement shall provide for the completion of such additional stockholder questionnaires, surveys or reviews as the parties deem are necessary in order to reasonably ensure that the Consideration Distribution satisfies the requirements for a private placement of securities as contemplated by Section 4(2) the Securities Act.

8.2 Effect of Termination. Each party’s right of termination under Section 8.1 is in addition to any other rights it may have under this Agreement or otherwise, and the exercise of a right of termination will not be an election of remedies. If this Agreement is terminated pursuant to

-17-

ARTICLE IX

Indemnification

9.1 Survival. The representations and warranties of any of the parties hereto contained in this Agreement shall survive the Closing. Except as otherwise provided in this Agreement, the covenants and agreements of the Parties contained in this Agreement shall survive Closing and shall continue in full force and effect indefinitely or for the shorter period specified in this Agreement. Any breach of representation, warranty, covenant or agreement in respect of which indemnity may be sought under this Agreement shall survive the time at which it would otherwise terminate if notice of the inaccuracy or breach thereof giving rise to such right of indemnity shall have been given to the party against whom such indemnity may be sought prior to such time.

9.2 Indemnification.

(a) From and after Closing, Acquirer hereby indemnifies Transferor and its Affiliates and Representatives against and agrees to hold Transferor harmless from any and all damage, loss, liability and expense (including, without limitation, reasonable expenses of investigation and reasonable attorneys’ fees and expenses in connection with any action, suit or proceeding) (“Damages”) actually incurred or suffered by Transferor arising out of or resulting from any inaccuracy or breach of any representation and warranty (each such inaccuracy and breach, a “Warranty Breach”) or breach of a covenant, in each case of Acquirer contained in this Agreement.

(b) From and after Closing, Transferor and each Systems Member hereby indemnifies Acquirer and its Affiliates and Representatives against and agrees to hold it harmless from any and all Damages actually incurred or suffered by Acquirer (i) arising out of or related in any way to any Warranty Breach or breach of a covenant of Transferor in this Agreement or in the Information Statement (other than Acquirer Information), exhibits, schedules or certificates to, or delivered in connection with, this Agreement; (ii) the consummation of the Contemplated Transaction without compliance with the bulk sales provisions of the Uniform Commercial Code or other statutes in any state having a similar purpose; and (iii) sales or other transfer taxes incurred in connection with the Contemplated Transaction.

9.3 Procedures.

(a) The party seeking indemnification under Section 9.2 (the “Indemnified Party”) agrees to give prompt notice to the party against whom indemnity is sought (the “Indemnifying Party”) of the assertion of any claim, or the commencement of any suit, action or

-18-

proceeding (“Claim”) in respect of which indemnity may be sought under such Section and will provide the Indemnifying Party such information with respect thereto that the Indemnifying Party may reasonably request. The failure to so notify the Indemnifying Party shall not relieve the Indemnifying Party of its obligations hereunder, except to the extent such failure shall have adversely prejudiced the Indemnifying Party.

(b) The Indemnified Party shall obtain the prior written consent of the Indemnifying Party (which shall not be unreasonably withheld, conditioned or delayed) before entering into any settlement of any Claim asserted by any third party (“Third Party Claim”).

(c) Each of Acquirer and Transferor shall cooperate, and cause their respective Affiliates to cooperate, in the defense or prosecution of any Third Party Claim and shall furnish or cause to be furnished such records, information and testimony, and attend such conferences, discovery proceedings, hearings, trials or appeals, as may be reasonably requested in connection therewith.

(d) Each Indemnified Party must mitigate in accordance with applicable Law any loss for which such Indemnified Party seeks indemnification under this Agreement. If such Indemnified Party mitigates its loss after the Indemnifying Party has paid the Indemnified Party under any indemnification provision of this Agreement in respect of that loss, the Indemnified Party must promptly notify the Indemnifying Party and promptly pay to the Indemnifying Party the extent of the value of the benefit (or, if less, the amount of any such loss previously paid by the Indemnifying Party) to the Indemnified Party of that mitigation (less the Indemnified Party’s reasonable costs of mitigation).

(e) Each Indemnified Party shall use reasonable efforts to collect any amounts available under insurance coverage, or from any other person alleged to be responsible, for any Damages payable under Section 9.2.

The right to indemnification, payment of Damages or other remedy based on such representations, warranties, covenants, and obligations will not be affected by any investigation conducted with respect to, or any Knowledge acquired (or capable of being acquired) at any time, whether before or after the execution and delivery of this Agreement or the Closing Date, with respect to the accuracy or inaccuracy of or compliance with, any such representation, warranty, covenant, or obligation. The waiver of any condition based on the accuracy of any representation or warranty, or on the performance of or compliance with any covenant or obligation, will not affect the right to indemnification, payment of Damages, or other remedy based on such representations, warranties, covenants, and obligations.

9.4 Assignment of Claims. If the Indemnified Party receives any payment from an Indemnifying Party in respect of any Damages pursuant to Section 9.2 and the Indemnified Party could have recovered all or a part of such Damages from a third party (other than any Subsidiary of Acquirer or any current or former employee or agent of such persons) (a “Potential Contributor”) based on the underlying Claim asserted against the Indemnifying Party, the Indemnified Party shall assign such of its rights to proceed against the Potential Contributor as are necessary to permit the Indemnifying Party to recover from the Potential Contributor the amount of such payment.

-19-

9.5 Exclusivity. After the Closing, Section 9.2 will provide the exclusive remedy for any misrepresentation, breach of warranty, covenant or other agreement or other claim arising out of this Agreement or the transactions contemplated hereby, other than any claim for gross negligence, intentional misrepresentation, willful misconduct or fraud. Notwithstanding the foregoing, it is understood that nothing herein shall prohibit any party hereto from exercising its rights to seek equitable relief with respect to a breach of covenant or agreement under any Transaction Document.

9.6 Indemnification and Payment of Damages by Systems Members. Anything in this Agreement to the contrary notwithstanding, (a) with respect to each claim for indemnification under this Section 9, Acquirer must first proceed against Transferor, prior to the Consideration Distribution, before proceeding against any equityholder of Transferor (including any of the Systems Members), and (b) the indemnification obligation of a Systems Member under this Section 9 shall be limited to the value, as of the Closing, of the Consideration received by such Systems Member pursuant to the Consideration Distribution.
