Ladies and Gentlemen:

The undersigned hereby tenders to CKH Acquisition Corporation, a Delaware corporation (the "Purchaser") and an indirect wholly owned subsidiary of Roche Holding Ltd, a joint stock company organized under the laws of Switzerland, the above-described shares of common stock, par value $0.01 per share (together with the associated preferred stock purchase rights, the "Shares"), of Illumina, Inc., a Delaware corporation (the "Company"), pursuant to the Purchaser's offer to purchase all outstanding Shares at $44.50 per Share, net to the seller in cash, without interest and less applicable withholding taxes, upon the terms and subject to the conditions set forth in the Offer to Purchase dated January 27, 2012, receipt of which is hereby acknowledged, and in this Letter of Transmittal (which, together with any amendments or supplements thereto or hereto, collectively constitute the "Offer"). The Offer expires at 12:00 Midnight, New York City time, at the end of the day on Friday, February 24, 2012, unless extended by the Purchaser as described in the Offer to Purchase (as extended, the "Expiration Date"). The Purchaser reserves the right to transfer or assign, in whole or from time to time in part, to one or more of its affiliates the right to purchase Shares tendered pursuant to the Offer, but any such transfer or assignment will not relieve the Purchaser of its obligations under the Offer or prejudice your rights to receive payment for Shares validly tendered and accepted for payment.

Upon the terms and subject to the conditions of the Offer and effective upon acceptance for payment of and payment for the Shares tendered herewith, the undersigned hereby sells, assigns and transfers to, or upon the order of, the Purchaser all right, title and interest in and to all the Shares that are being tendered hereby (and any and all other Shares or other securities issued or issuable in respect thereof on or after January 27, 2012) and appoints the Depositary the true and lawful agent and attorney-in-fact of the undersigned with respect to such Shares (and all such other Shares or securities), with full power of substitution (such power of attorney being deemed to be an irrevocable power coupled with an interest), to (i) deliver certificates for such Shares (and all such other Shares or securities), or transfer ownership of such Shares (and all such other Shares or securities) on the account books maintained by the Book-Entry Transfer Facility, together, in any such case, with all accompanying evidences of transfer and authenticity, to or upon the order of the Purchaser, (ii) present such Shares (and all such other Shares or securities) for transfer on the books of the Company and (iii) receive all benefits and otherwise exercise all rights of beneficial ownership of such Shares (and all such other Shares or securities), all in accordance with the terms of the Offer.

The undersigned hereby irrevocably appoints Bruce Resnick and Frederick C. Kentz III in their respective capacities as officers of the Purchaser, the attorneys and proxies of the undersigned, each with full power of substitution, to exercise all voting and other rights of the undersigned in such manner as each such attorney and proxy or his substitute shall in his sole discretion deem proper, with respect to all of the Shares tendered hereby which have been accepted for payment by the Purchaser prior to the time of any vote or other action (and any and all other Shares or other securities issued or issuable in respect thereof on or after January 27, 2012), at any meeting of shareholders of the Company (whether annual or special and whether or not an adjourned meeting), by written consent or otherwise. This proxy is irrevocable and is granted in consideration of, and is effective upon, the acceptance for payment of such Shares by the Purchaser in accordance with the terms of the Offer. Such acceptance for payment shall revoke any other proxy or written consent granted by the undersigned at any time with respect to such Shares (and all such other Shares or securities), and no subsequent proxies will be given or written consents will be executed by the undersigned (and if given or executed, will not be deemed to be effective).

The undersigned hereby represents and warrants that the undersigned has full power and authority to tender, sell, assign and transfer the Shares tendered herein (and any and all other Shares or other securities issued or issuable in respect thereof on or after January 27, 2012) and that when the same are accepted for payment by the Purchaser, the Purchaser will acquire good and unencumbered title thereto, free and clear of all liens, restrictions, charges and encumbrances and not subject to any adverse claims. The undersigned will, upon request, execute and deliver any additional documents deemed by the Depositary or the Purchaser to be necessary or desirable to complete the sale, assignment and transfer of the Shares tendered hereby (and all such other Shares or securities).

All authority herein conferred or agreed to be conferred shall survive the death or incapacity of the undersigned, and any obligation of the undersigned hereunder shall be binding upon the heirs, personal representatives, successors and assigns of the undersigned. Except as stated in the Offer, this tender is irrevocable.

The undersigned understands that tenders of Shares pursuant to any one of the procedures described in Section 3 of the Offer to Purchase and in the instructions hereto will constitute an agreement between the undersigned and the Purchaser upon the terms and subject to the conditions of the Offer. Without limiting the

foregoing, if the price to be paid in the Offer is amended, the price to be paid to the undersigned will be the amended price notwithstanding the fact that a different price is stated in this Letter of Transmittal.

Unless otherwise indicated under "Special Payment Instructions," please issue the check for the purchase price of any Shares purchased, and return any Shares not tendered or not purchased, in the name(s) of the undersigned (and, in the case of Shares tendered by book-entry transfer, by credit to the account at the Book-Entry Transfer Facility). Similarly, unless otherwise indicated under "Special Delivery Instructions," please mail the check for the purchase price of any Shares purchased and any certificates for Shares not tendered or not purchased (and accompanying documents, as appropriate) to the undersigned at the address shown below the undersigned's signature(s). In the event that both "Special Payment Instructions" and "Special Delivery Instructions" are completed, please issue the check for the purchase price of any Shares purchased and return any Shares not tendered or not purchased in the name(s) of, and mail said check and any certificates to, the person(s) so indicated.

INSTRUCTIONS

Forming Part of the Terms and Conditions of the Offer

1. Guarantee of Signatures. Except as otherwise provided below, all signatures on this Letter of Transmittal must be guaranteed by a financial institution (including most banks, savings and loan associations and brokerage houses) that is a member of a recognized Medallion Program approved by The Securities Transfer Association, Inc., including the Securities Transfer Agents Medallion Program (STAMP), the Stock Exchange Medallion Program (SEMP) and the New York Stock Exchange, Inc. Medallion Signature Program (MSP) or any other "eligible guarantor institution" (as such term is defined in Rule 17Ad-15 under the Securities Exchange Act of 1934, as amended) (each an "Eligible Institution"). Signatures on this Letter of Transmittal need not be guaranteed (i) if this Letter of Transmittal is signed by the registered holder(s) of the Shares (which term, for purposes of this document, shall include any participant in the Book-Entry Transfer Facility whose name appears on a security position listing as the owner of Shares) tendered herewith and such holder(s) have not completed the box entitled "Special Payment Instructions" on this Letter of Transmittal or (ii) if such Shares are tendered for the account of an Eligible Institution. See Instruction 5.

2. Delivery of Letter of Transmittal and Shares. This Letter of Transmittal is to be used either if certificates are to be forwarded herewith or, unless an Agent's Message is utilized, if delivery of Shares is to be made by book-entry transfer pursuant to the procedures set forth in Section 3 of the Offer to Purchase. Certificates for all physically delivered Shares, or a confirmation of a book-entry transfer into the Depositary's account at the Book-Entry Transfer Facility of all Shares delivered electronically, as well as a properly completed and duly executed Letter of Transmittal, with any required signature guarantees (or a manually signed facsimile thereof) or, in the case of a book-entry transfer, an Agent's Message, and any other documents required by this Letter of Transmittal, must be received by the Depositary at one of its addresses set forth on the front page of this Letter of Transmittal on or prior to the Expiration Date.

Shareholders whose certificates for Shares are not immediately available or shareholders who cannot deliver their certificates and all other required documents to the Depositary or who cannot comply with the procedures for book-entry transfer on or prior to the Expiration Date may tender their Shares pursuant to the guaranteed delivery procedure set forth in Section 3 of the Offer to Purchase.

Under the guaranteed delivery procedure:

(i): such tender must be made by or through an Eligible Institution;
(ii): a properly completed and duly executed Notice of Guaranteed Delivery substantially in the form provided by the Purchaser with the Offer to Purchase must be received by the Depositary on or prior to the Expiration Date; and
(iii): the certificates for all physically delivered Shares, or a confirmation of a book-entry transfer into the Depositary's account at the Book-Entry Transfer Facility of all Shares delivered electronically, as well as a properly completed and duly executed Letter of Transmittal with any required signature guarantee (or a manually signed facsimile thereof) or, in the case of a book-entry delivery, an Agent's Message and any other documents required by this Letter of Transmittal, must be received by the Depositary within three NASDAQ trading days after the date of execution of such Notice of Guaranteed Delivery, all as provided in Section 3 of the Offer to Purchase.

The method of delivery of Shares, this Letter of Transmittal and all other required documents, including through the Book-Entry Transfer Facility, is at the election and sole risk of the tendering shareholder and delivery will be deemed made only when actually received by the Depositary. If certificates for Shares are sent by mail, we recommend registered mail with return receipt requested, properly insured, in time to be received on or prior to the Expiration Date. In all cases, sufficient time should be allowed to ensure timely delivery.

No alternative, conditional or contingent tenders will be accepted, and no fractional Shares will be purchased. By executing this Letter of Transmittal (or a manually signed facsimile thereof), the tendering shareholder waives any right to receive any notice of the acceptance for payment of the Shares.

3. Inadequate Space. If the space provided herein is inadequate, the certificate numbers and/or the number of Shares should be listed on a separate signed schedule attached hereto.

4. Partial Tenders (not applicable to shareholders who tender by book-entry transfer). If fewer than all the Shares represented by any certificate delivered to the Depositary are to be tendered, fill in the number of Shares

which are to be tendered in the box entitled "Number of Shares Tendered". In such case, if Shares are purchased, a new certificate for the remainder of the Shares represented by the old certificate will be issued and sent to the person(s) signing this Letter of Transmittal, unless otherwise provided in the appropriate box on this Letter of Transmittal, as promptly as practicable following the expiration of the Offer. All Shares represented by certificates delivered to the Depositary will be deemed to have been tendered unless otherwise indicated.

5. Signatures on Letter of Transmittal; Stock Powers and Endorsements. If this Letter of Transmittal is signed by the registered holder(s) of the Shares tendered hereby, the signature(s) must correspond with the name(s) as written on the face of the certificates without alteration or any change whatsoever.

If any of the Shares tendered hereby is held of record by two or more persons, all such persons must sign this Letter of Transmittal.

If any of the Shares tendered hereby are registered in different names on different certificates, it will be necessary to complete, sign and submit as many separate Letters of Transmittal as there are different registrations of certificates.

If this Letter of Transmittal is signed by the registered holder(s) of the Shares tendered hereby, no endorsements of certificates or separate stock powers are required unless payment of the purchase price is to be made, or Shares not tendered or not accepted for payment are to be returned, in the name of any person other than the registered holder(s). Signatures on any such certificates or stock powers must be guaranteed by an Eligible Institution.

If this Letter of Transmittal is signed by a person other than the registered holder(s) of the Shares tendered hereby, certificates must be endorsed or accompanied by appropriate stock powers, in either case, signed exactly as the name(s) of the registered holder(s) appear(s) on the certificates for such Shares. Signature(s) on any such certificates or stock powers must be guaranteed by an Eligible Institution.

If this Letter of Transmittal or any certificate or stock power is signed by a trustee, executor, administrator, guardian, attorney-in-fact, officer of a corporation or other person acting in a fiduciary or representative capacity, such person should so indicate when signing, and proper evidence satisfactory to the Purchaser of the authority of such person so to act must be submitted.

6. Stock Transfer Taxes. Except as otherwise provided in this Instruction 6, the Purchaser will pay any stock transfer taxes with respect to the sale and transfer of any Shares to it or its order pursuant to the Offer. If, however, payment of the purchase price is to be made to, or Shares not tendered or not accepted for payment are to be returned in the name of, any person other than the registered holder(s), or if a transfer tax is imposed for any reason other than the sale or transfer of Shares to the Purchaser pursuant to the Offer, then the amount of any stock transfer taxes (whether imposed on the registered holder(s), such other person or otherwise) will be deducted from the purchase price unless satisfactory evidence of the payment of such taxes, or exemption therefrom, is submitted herewith.

7. Special Payment and Delivery Instructions. If the check for the purchase price of any Shares purchased is to be issued, or any Shares not tendered or not purchased are to be returned, in the name of a person other than the person(s) signing this Letter of Transmittal or if the check or any certificates for Shares not tendered or not purchased are to be mailed to someone other than the person(s) signing this Letter of Transmittal or to the person(s) signing this Letter of Transmittal at an address other than that shown above, the appropriate boxes on this Letter of Transmittal should be completed. Shareholders tendering Shares by book-entry transfer may request that Shares not purchased be credited to such account at the Book-Entry Transfer Facility as such shareholder may designate under "Special Payment Instructions". If no such instructions are given, any such Shares not purchased will be returned by crediting the account at the Book-Entry Transfer Facility designated above.

8. Substitute Form W-9. Under the U.S. federal income tax laws, unless certain certification requirements are met, the Depositary generally will be required to withhold at the applicable backup withholding rate (currently 28%) from any payments made to certain shareholders pursuant to the Offer. In order to avoid such backup withholding, each tendering shareholder, and, if applicable, each other payee, must provide the Depositary with such shareholder's or payee's correct taxpayer identification number and certify that such shareholder or payee is not subject to such backup withholding by completing the Substitute Form W-9 set forth above. In general, if a shareholder or payee is an individual, the taxpayer identification number is the social security number of such individual. If the shareholder or payee does not provide the Depositary with its correct taxpayer identification number, the shareholder or payee may be subject to a $50 penalty imposed by the Internal Revenue Service.

Certain shareholders or payees (including, among others, all corporations and certain foreign individuals) are not subject to these backup withholding and reporting requirements. In order to satisfy the Depositary that a foreign individual qualifies as an exempt recipient, such shareholder or payee must submit to the Depositary the appropriate properly completed Internal Revenue Service form (generally Form W-8BEN, which the Depositary will provide upon request), signed under penalties of perjury, attesting to that individual's exempt status. Such form can be obtained from the Depositary or the Internal Revenue Service (www.irs.gov/formspubs/index.html). For further information concerning backup withholding and instructions for completing the Substitute Form W-9 (including how to obtain a taxpayer identification number if you do not have one and how to complete the Substitute Form W-9 if Shares are held in more than one name), consult the enclosed Guidelines for Certification of Taxpayer Identification Number on Substitute Form W-9.

Failure to complete the Substitute Form W-9 will not, by itself, cause Shares to be deemed invalidly tendered but may require the Depositary to withhold 28% of the amount of any payments made pursuant to the Offer. Backup withholding is not an additional tax. Rather, the federal income tax liability of a person subject to backup withholding will be reduced by the amount of tax withheld. If withholding results in an overpayment of taxes, a refund may be obtained, provided that the required information is timely furnished to the Internal Revenue Service. Failure to complete and return the Substitute Form W-9 may result in backup withholding of 28% of any payments made to you pursuant to the Offer. Please review the enclosed Guidelines for Certification of Taxpayer Identification Number on Substitute Form W-9 for additional details.

9. Mutilated, Lost, Stolen or Destroyed Certificates. If the certificate(s) representing Shares to be tendered have been mutilated, lost, stolen or destroyed, shareholders should (i) complete this Letter of Transmittal and check the appropriate box above and (ii) contact the Company's transfer agent, Computershare Trust Company, N.A., immediately by calling (800) 251-4215. The shareholder will then be instructed as to the steps that must be taken in order to replace the certificate. This Letter of Transmittal and related documents cannot be processed until the procedures for replacing lost, mutilated, destroyed or stolen certificates have been followed.

10. Questions or Requests for Assistance or Additional Copies. Questions or requests for assistance or additional copies of the Offer to Purchase, this Letter of Transmittal and the Notice of Guaranteed Delivery may be obtained (at Purchaser's expense) from the Information Agent or the Dealer Managers at their respective addresses or telephone numbers set forth below.

11. Waiver of Conditions. The Purchaser reserves the right to waive (in its reasonable discretion in whole or in part at any time or from time to time before the Expiration Date) any of the specified conditions of the Offer in the case of any Shares tendered.

IMPORTANT: This Letter of Transmittal (or a manually signed facsimile thereof) together with any signature guarantees, or, in the case of a book-entry transfer, an Agent's Message, and any other required documents, must be received by the Depositary on or prior to the Expiration Date and either certificates for tendered Shares must be received by the Depositary or Shares must be delivered pursuant to the procedures for book-entry transfer, in each case on or prior to the Expiration Date, or the tendering shareholder must comply with the procedures for guaranteed delivery.

Foreign payees who are not subject to backup withholding should complete the appropriate IRS Form W-8 and return it to the payor.

Privacy Act Notice

Section 6109 of the Code requires most recipients of dividend, interest or other payments to give their correct taxpayer identification numbers to payors who must report the payments to the IRS. The IRS uses the numbers for identification purposes and to help verify the accuracy of tax returns. It 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. It may also disclose this information to other countries under a tax treaty, to federal and state agencies to enforce federal nontax criminal laws, and to federal law enforcement and intelligence agencies to combat terrorism.

Payees must provide payors with their taxpayer identification numbers whether or not they are required to file tax returns. Payors must generally withhold 28% of taxable interest, dividend and certain other payments to a payee who does not furnish a taxpayer identification number to a payor. Certain penalties may also apply.

Penalties

(1) Penalty for Failure to Furnish Taxpayer Identification Number—If you fail to furnish your correct taxpayer identification number to a payor, you are subject to a penalty of $50 for each such failure unless your failure is due to reasonable cause and not to willful neglect.

(2) Civil Penalty for False Information With Respect to Withholding—If you make a false statement with no reasonable basis which results in no imposition of backup withholding, you are subject to a penalty of $500.

(3) Criminal Penalty for Falsifying Information—Willfully falsifying certifications or affirmations may subject you to criminal penalties including fines and/or imprisonment.
