IMPORTANT: To be effective, this Election Form and Letter of Transmittal, together with the certificate(s) representing the related shares of Union Bankshares Common Stock (or a properly completed Notice of Guaranteed Delivery), must be received by Computershare Trust Co., Inc. (the “Exchange Agent”) NO LATER THAN 5:00 P.M., NEW YORK CITY TIME, ON DECEMBER 20, 2007. Deliveries made to addresses other than the address of the Exchange Agent set forth in Box E will not constitute valid deliveries and the Exchange Agent will have no responsibility for them.

CAMDEN MAY ADJUST AN ELECTION. The election made above will be honored to the extent possible, but because of the requirement that 40% of the total number of shares of Union Bankshares Common Stock outstanding immediately prior to the effective time of the merger will be converted into the right to receive the cash consideration, and 60% of the total number of shares of Union Bankshares Common Stock immediately prior to the effective time of the merger will be converted into the right to receive Camden Common Stock, whether you receive the amount of cash and/or Camden Common Stock that you elect will depend in part on the elections of other Union Bankshares shareholders. Therefore, you may not receive exactly the form of consideration that you elect, and you may instead receive a pro rata amount of cash and Camden Common Stock. Please see the examples set forth in the section of the Proxy Statement/Prospectus dated October 23, 2007, as amended, titled “The Merger Agreement—Allocation Procedures” beginning on page 53.

If you have a preference for receiving either cash or Camden Common Stock or a mixed election for your shares of Union Bankshares Common Stock, you should return this Election Form and Letter of Transmittal indicating your preference. Union Bankshares shareholders who make an election will be accorded priority over those shareholders who make no election in instances where the cash consideration or stock consideration must be re-allocated in order to achieve the required ratio of Union Bankshares shares being converted into the right to receive cash and Camden Common Stock. If you do not make an election, you will be allocated cash and/or Camden Common Stock depending on the elections made by other Union Bankshares shareholders.HOWEVER, EVEN IF YOU DO MAKE AN ELECTION, YOU MIGHT NOT RECEIVE THE MERGER CONSIDERATION THAT YOU ELECTED.

FRACTIONAL SHARE INTERESTS. No fractional shares of Camden Common Stock will be issued in connection with the merger. A holder of Union Bankshares Common Stock who receives Camden Common Stock and is entitled to a fractional share will be paid cash in lieu of such fractional share. Such Union Bankshares holder will be paid an amount of cash (without interest) based on the average last sale price of Camden Common Stock as reported on the American Stock Exchange over the five (5) trading days immediately preceding the effective date of the merger, rounded to the nearest whole cent.

(3) Joint Forms of Election. For purposes of this Election Form and Letter of Transmittal and the allocation procedures described under “CAMDEN MAY ADJUST AN ELECTION” on the Election Form and Letter of Transmittal, holders of shares of Union Bankshares Common Stock who join in making a joint election will be considered to be a single holder of such shares.

Smith” on another) and by persons who may be considered to own each other’s

shares by reason of the ownership attribution rules contained in Section 318(a) of the Internal Revenue Code of 1986, as amended. If the Election Form and Letter of Transmittal are submitted as a joint Election Form and Letter of Transmittal, each record holder of shares of Union Bankshares Common Stock covered thereby must properly sign the Election Form and Letter of Transmittal, attaching additional sheets if necessary. The signatures of such holders will be deemed to constitute a certification that the persons submitting a joint Election Form and Letter of Transmittal are eligible to do so.

However, upon the request of Camden, such record holder will be required to certify to the satisfaction of Camden that such record holder holds such shares of Union Bankshares Common Stock as nominee for the beneficial owners of such shares.

List the stock certificate number and number of shares represented by each Union Bankshares Common Stock certificate surrendered for exchange in the space provided in Box A of the Election Form and Letter of Transmittal.

You do not need to complete the column “Certificate No.” for book-entry shares held in the DRIP. If the space provided is inadequate, use a separate schedule and attach it to the Election Form and Letter of Transmittal. The total number of shares of Union Bankshares Common Stock surrendered for exchange for cash and/or Camden Common Stock plus any shares held in the DRIP should equal the total number of shares of Union Bankshares Common Stock held of record by the holder as indicated on the books of Union Bankshares. The Exchange Agent may delay the exchange until any difference in the number of shares of Union Bankshares Common Stock surrendered and the number of shares of Union Bankshares Common Stock held of record is resolved.

(3) Signature Guarantee. If any Payment Check(s) and/or certificate(s) for Camden Common Stock is to be issued in a name different from that appearing on the face of the surrendered certificate(s), the certificate(s) must be properly endorsed by the registered holder(s) thereof or accompanied by appropriate stock powers properly executed and the signature(s) to the endorsement on the stock power must be guaranteed by a commercial bank or trust company located in the United States or by a firm of brokers having membership in a national securities exchange and Box F — “SIGNATURE(S) GUARANTEED” — on the Letter of Transmittal must be completed.

(4) Issuance of Payment Check(s) and Certificate(s). The Payment Check(s) and/or certificate(s) for shares of Camden Common Stock will be issued in the name of the registered holder(s) as inscribed on the surrendered certificate(s). However, if the name is incorrect or wrong, it may be corrected by following Instruction C(5) below. If the Payment Check(s) and/or certificate(s) for shares of Camden Common Stock are to be issued in the name of someone other than the registered holder(s) of the surrendered certificate(s), you must follow Instruction C(7) below.

Brown,” with the signature guaranteed as described in Instruction C(3) and Box F should be completed.

(6) Special Delivery Instructions.

(7) Transfer of Shares and Rights to Receive Proceeds. If any Payment Check(s) and/or any certificate(s) for shares of Camden Common Stock is to be issued to a person other than the registered holder(s) of the Union Bankshares Common Stock surrendered for exchange, then:

•

The certificate(s) representing shares of Union Bankshares Common Stock surrendered for exchange must be endorsed by the registered holder(s) or accompanied by an appropriate stock power, with the signature(s) guaranteed in the usual form by a bank or brokerage firm acceptable to the Exchange Agent as described in Instruction C(3);

•

Box G — “SPECIAL ISSUANCE INSTRUCTIONS” — on the Election Form and Letter of Transmittal must be completed.

(8) Backup Withholding. Each person surrendering certificate(s) representing shares of Union Bankshares Common Stock to the Exchange Agent is required to provide the Exchange Agent with a correct Taxpayer Identification Number (“TIN”) on Substitute Form W-9, which is provided herein on Box D, and to indicate, if applicable, that such person is not subject to backup withholding. If such person is an individual, the TIN is his or her social security number. If the Exchange Agent is not provided with the correct TIN, such person may be subject to a $50 penalty imposed by the Internal Revenue Service. In addition, failure to provide the information on the form may subject such person to federal income tax withholding on any payment at the then applicable rate. This form may be used to certify that such person is not a United States citizen or resident. If Box G “SPECIAL ISSUANCE INSTRUCTIONS” is completed, the person named in Box G will be considered the person surrendering certificate(s) representing shares of Union Bankshares Common Stock for purposes of backup withholding and such person should complete the Substitute W-9.

Exempt shareholders (including, among others, certain foreign individuals) are not subject to these backup withholding and reporting requirements and should write “Exempt” on the face of the Substitute Form W-9. However, such shareholders should also provide a TIN to avoid erroneous backup withholding.

(9) Notice of Defects; Resolution of Dispute. None of Union Bankshares, Camden or the Exchange Agent will be under any obligation to notify you or anyone else that the Exchange Agent has not received a properly completed Election Form and Letter of Transmittal or that any of such forms are defective in any way.

The Exchange Agent shall have reasonable discretion to determine whether any election, revocation or change of any Election Form and Letter of Transmittal has been properly made and to disregard immaterial defects in any Election Form and Letter of Transmittal, and any good faith decisions of the Exchange Agent regarding such matters shall be binding and conclusive.

(10) Questions and Requests for Information or Assistance. If you have any questions, need assistance to complete the Election Form and Letter of Transmittal or need additional copies of the Election Form and Letter of Transmittal or the Proxy Statement/Prospectus, please contact Georgeson Inc. at (866) 651-3212.

Following the effective time of the merger, the Exchange Agent will make the allocations of cash and Camden Common Stock to be received by holders of Union Bankshares Common Stock or their designees in accordance with the Merger Agreement and the Election Forms and Letters of Transmittal. The Exchange Agent will then issue and mail to you a certificate representing shares of Camden Common Stock and/or a Payment Check for any cash to which you are entitled (and, if applicable, a check for cash in lieu of a fractional share), provided you have delivered the required certificate(s) for your shares of Union Bankshares Common Stock in accordance with the terms of the Election Form and Letter of Transmittal.

1.	What is the Election Form and Letter of Transmittal?

The enclosed Election Form and Letter of Transmittal is being mailed to each shareholder holding Union Bankshares stock certificates. The Election Form and Letter of Transmittal does two things. First, it lets us know your preferred form of payment for your shares of Union Bankshares common stock (i.e., shares of Camden common stock and/or cash). Second, it allows you to surrender your certificates for Union Bankshares common stock in order to receive payment for the shares of Union Bankshares common stock you own. If you also hold shares with a brokerage firm, you will receive election instructions from that firm.

2.	How do I complete the “Election Form and Letter of Transmittal”?

The Election Form and Letter of Transmittal is divided into Boxes A through H. Detailed instructions for completing each Box are set forth in the “Instructions for Completing Election Form and Letter of Transmittal.” If you have any questions or need assistance to complete the Election Form and Letter of Transmittal, please contact the Information Agent at (866) 651-3212.

When completed, please send the Election Form and Letter of Transmittal to Computershare Trust Co., Inc. (the “Exchange Agent”) in the enclosed envelope along with your certificates for your shares of Union Bankshares common stock, and any additional documentation that may be required, so that you can make your election to receive cash, shares of Camden common stock or a combination of cash and shares of Camden common stock.

If you do not have the envelope, you may send the Election Form and Letter of Transmittal and any additional documentation to: Computershare Trust Co., Inc., c/o Corporate Actions, P.O. Box 859208, Braintree, MA 02185-9208.Please do not return any documents to Union Bankshares or Camden.

If you are mailing stock certificates, we recommend that they be sent (using the return envelope provided) registered mail, properly insured, with return receipt requested.

If you need to submit the Notice of Guaranteed Delivery, it may be mailed to the Exchange Agent with your Election Form and Letter of Transmittal, or the institution completing and executing the Notice of Guaranteed Delivery may fax it to the Exchange Agent at (781) 930-4900.

3.	What happens if I do not return an Election Form and Letter of Transmittal or miss the Election Deadline?

If you do not respond prior to 5:00 p.m., New York City Time, on December 20, 2007, you will be deemed to have made “No Election” which means you will receive shares of Camden common stock and/or cash in exchange for your shares of Union Bankshares common stock, as determined according to the proration procedures in the merger agreement, such that 40% of the shares of Union Bankshares common stock outstanding prior to the merger will be converted into cash, and 60% of the shares of Union Bankshares common stock outstanding prior to the merger will be converted into Camden common stock. Also, until you submit your certificates for shares of Union Bankshares common stock, the cash and/or shares of Camden common stock cannot be sent to you.

Camden cannot ensure that all Union Bankshares shareholders will receive their election choices. The merger agreement provides that 60% of the outstanding shares of Union Bankshares common stock will be exchanged for Camden common stock and 40% of the outstanding shares of Union Bankshares common stock will be exchanged for cash.Camden will attempt to comply with the election requests of Union Bankshares shareholders. However, if shareholders owning more than 40% of the outstanding shares of Union Bankshares common stock elect to receive cash, the number of shares of Union Bankshares common stock that will be exchanged for cash will be reduced on a pro rata basis.

12.

May I continue to trade my Union Bankshares shares after I surrender my stock certificate(s)?

No. Once you submit your stock certificates, you may no longer trade your shares, though the stock will continue to trade until the merger is effective.

For interest and dividend payments, and certain payments made with respect to readily tradable instruments, generally you will have 60 days to get a TIN and give it to the requester before you are subject to backup withholding on payments. The 60-day rule does not apply to other types of payments. You will be subject to backup withholding on all such payments until you provide your TIN to the requester.

Privacy Notice

Section 6109 of the Internal Revenue Code requires you to provide your correct TIN to persons who must file information returns with the IRS to report interest, dividends, and certain other income paid to you, mortgage interest you paid, the acquisition or abandonment of secured property, cancellation of debt, or contributions you made to an IRA, or Archer MSA or HSA. The IRS uses the numbers for identification purposes and to help verify the accuracy of your tax return. The IRS may also provide this information to the Department of Justice for civil and criminal litigation, and to cities, states, the District of Columbia, and U.S. possessions to carry out their tax laws. We may also disclose this information to other countries under a tax treaty, to federal and state agencies to enforce federal nontax criminal laws, or to federal law enforcement and intelligence agencies to combat terrorism.

You must provide your TIN whether or not you are required to file a tax return. Payers must generally withhold 28% of taxable interest, dividend, and certain other payments to a payee who does not give a TIN to a payer. Certain penalties may also apply.
